The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body in the underfloor space is provided on the floor surface. Next, the outlet of the trap body is connected to the sewage side pipe through this opening. Further, the male screw portion of the flange portion is inserted into the opening of the waterproof pan for a washing machine, and then screwed into the female screw of the trap body. Thus, the trap body and the flange member are attached to the washing machine waterproof pan so that the flange lower surface of the flange member and the upper surface of the convex portion of the trap body sandwich the periphery of the opening of the waterproof pan for washing machine. Fixed.
Furthermore, a waterproof pan for a washing machine is fixed on the floor using screws or the like.
In addition, the water bottle is arranged so as to hang inside the flange member, and the deodorizing cylinder in which the washing machine connection pipe is housed is arranged so that the lower end is housed in the water bottle. The upper end is watertightly connected to the inner surface of the flange member. In this state, the opening inside the flange member functions as a drain outlet. Furthermore, after setting the eye plate member at the drain outlet and connecting the washing machine drain hose to the washing machine connection pipe, place the leg of the washing machine on the footrest, and the washing machine waterproof pan and drain The trap and the washing machine are completed.

上記のように構成された洗濯機用防水パンと排水トラップは、以下のようにして使用される。
洗濯機を使用し、洗濯機より排水が生じると、洗濯機からの排水は、洗濯機用排水ホースから、洗濯機用接続管を介し、封水椀内部に流入して溜まり、充分に溜まると封水椀の側面に設けられた開口から溢れ出す。封水椀から流出した排水は、トラップ本体内部から排出口を介して下水側に排出される。
また、洗濯機自体や洗濯機用排水ホースの破損等により、洗濯機用防水パンの底面上に排水が生じると、排水は、排水口の目皿部材を通過し、防臭筒内部、封水椀内部、封水椀の上方の開口、トラップ本体内部、排出口、の順番に通過し、最終的に下水側に排出される。
また、上記のように構成した排水トラップにおいて、排水トラップに排水が行われると、封水椀内部に、側面の開口の下端の高さまで排水が溜まる。これにより、排水口又は洗濯機用接続管から封水椀の側面の開口部下端までの流路に、排水で満たされた部分が形成される。この溜まった排水を封水と呼び、下水側から臭気や害虫類が屋内側に侵入しようとしても、この封水によってそれ以上屋内側に侵入されることを防止ることができる。このように、下水側から臭気や害虫類が屋内側に侵入することを防止する機能をトラップ機能と呼ぶ。
The washing machine waterproof pan and drain trap configured as described above are used as follows.
When wastewater is generated from the washing machine using the washing machine, the wastewater from the washing machine flows into the inside of the sealed water bottle from the washing machine drain hose through the washing machine connection pipe, and accumulates sufficiently. It overflows from the opening provided on the side surface of the water seal. The waste water that has flowed out from the sealed water tank is discharged from the inside of the trap body to the sewage side through the discharge port.
In addition, if drainage occurs on the bottom surface of the waterproof pan for the washing machine due to damage to the washing machine itself or the drainage hose for the washing machine, the drainage passes through the eye plate member of the drainage port, inside the deodorizing cylinder, It passes in the order of the inside, the opening above the water bottle, the inside of the trap body, and the discharge port, and is finally discharged to the sewage side.
Further, in the drain trap configured as described above, when drainage is performed on the drain trap, the drainage collects up to the height of the lower end of the opening on the side surface inside the sealed water trough. Thereby, the part filled with the waste_water | drain is formed in the flow path from a drain outlet or a connecting pipe for washing machines to the lower end of the opening part of the side surface of a water bottle. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

ところで、洗濯機からの排水は、当然に洗濯を行った後の排水であり、油分等の汚れ、毛髪、毛糸屑、砂等様々な汚れ成分と、これを衣類等の洗濯物から分離し除くために使用された洗剤成分が混入している。このため、このような排水が通過する排水トラップの部材にこれらの汚れが付着し、排水トラップの各部材が汚れたり、雑菌が繁殖して異臭を生じたり、汚れ物質が堆積するなどして内部の排水流路が詰まったりする、という問題を生じる。このような問題を解決するため、排水トラップの部材の内、封水椀、防臭筒、洗濯機用接続管、目皿部材等は、トラップ本体から着脱して清掃することが可能に構成されている。しかしながら、実際には、洗濯機用防水パンの上方に洗濯機が配置され、排水トラップの上方が洗濯機に覆われることで、洗濯機用防水パンと洗濯機との間が狭くなり、トラップの部材の取り外し作業を行うために手を差し込む事が困難であったり、洗濯機の周壁の外側に取り出すことができない、といった問題があった。
そこで、特許文献1に記載の洗濯機用防水パンと排水トラップにおいては、足置き台の間部分の周壁を側面視円弧形状とし、足置き台上に載置された洗濯機の下端と、洗濯機用防水パンの周壁上面や底面との間に作業を可能とする隙間を確保すると共に、防臭筒等、比較的に大型の排水トラップの部材を横に倒すことで、洗濯機の周壁の外側に取り出すことができるように構成している。
特許文献1に明記はされてはいないが、排水トラップのトラップ本体及びフランジ部材を洗濯機用防水パンに接続するためにはネジによる接続が一般的に利用される。このため、トラップ本体及びフランジ部材の上方の開口も、ネジの形状に合わせて平面視円形に形成される場合が殆どで、この円形の開口に合わせて配置される封水椀、防臭筒等も平面視円形を成す場合が多い。この特許文献1に記載の洗濯機用防水パンと排水トラップの場合、足置き台の間部分の周壁を側面視円弧形状とすることで、平面視円形を成す封水椀、防臭筒を、横に倒して取り出す作業が容易になるように構成してなる。
By the way, the drainage from the washing machine is a drainage after washing, and various dirt components such as oil stains, hair, yarn waste, sand and the like are separated from the laundry such as clothes and removed. The detergent components used for the purpose are mixed. For this reason, these dirt adheres to the drain trap member through which such drainage passes, and each member of the drain trap becomes dirty, miscellaneous germs grow to produce a strange odor, and dirt substances accumulate, etc. This causes a problem that the drainage flow path of the water is clogged. In order to solve such a problem, the drain trap, the sealing bottle, the deodorizing cylinder, the connecting pipe for the washing machine, the eye plate member, and the like are configured to be removable from the trap body and cleaned. Yes. However, in reality, the washing machine is disposed above the waterproof pan for the washing machine, and the upper portion of the drain trap is covered with the washing machine, so that the gap between the waterproof pan for the washing machine and the washing machine becomes narrow, and the trap There was a problem that it was difficult to insert a hand to perform the removal work of the member, or it was not possible to take it out of the peripheral wall of the washing machine.
Therefore, in the waterproof pan for a washing machine and the drain trap described in Patent Document 1, the peripheral wall between the footrests has an arc shape when viewed from the side, the lower end of the washing machine placed on the footrests, The outside of the peripheral wall of the washing machine is secured by allowing a relatively large drainage trap member such as a deodorizing cylinder to lie down while ensuring a gap between the top and bottom surfaces of the peripheral wall of the machine waterproof pan. It can be taken out.
Although not specified in Patent Document 1, a screw connection is generally used to connect the trap body of the drain trap and the flange member to the waterproof pan for a washing machine. For this reason, the upper openings of the trap body and the flange member are also often formed in a circular shape in plan view in accordance with the shape of the screw. Often has a circular shape in plan view. In the case of the waterproof pan for a washing machine and the drain trap described in Patent Document 1, the peripheral wall of the portion between the footrests has an arc shape when viewed from the side, so that the sealed water bottle and the deodorizing cylinder that form a circular shape when viewed from above It is configured so that it is easy to take it down and take it out.

特開2008−88630号JP 2008-88630 A

上記のような特許文献1に記載の洗濯機用防水パンと排水トラップの場合、以下に記載するような問題点があった。
特許文献1に記載の洗濯機用防水パン含め、通常の洗濯機用防水パンにおいて、周壁の内面や底面上等、洗濯機用防水パンの内部に排水が生じることは、実際にはほとんど無い。
何故なら、洗濯機を支障無く利用する状況では、洗濯機の排水は直接排水トラップの内部に流れ込み、洗濯機用防水パンの内部、特に底面上を排水が流れることはない為である。
洗濯機用防水パンの内部に排水が流れる場合は、洗濯機や洗濯機用ホースが故障・破損し洗濯機用防水パンの内部に排水が漏出するという極めて希な場合か、または段落0005に記載したように、清掃時に封水椀を取り出す際に、封水椀を横倒しにして内部の排水が流出した場合のいずれかの場合に限られる。
洗濯機用防水パンは排水の処理を前提とした部材であり、樹脂材料で成型され、通常の床面に排水が溢れた場合とは異なり、排水が内部に流れ出しても、修復不可能な汚れの染みを生じたり、または破損を生じたり、といった問題を生じることなく排水を下水側に排出する事は可能である。しかしながら、洗濯機用防水パン内部に排水が流れ落ち、そのまま放置すれば、排水の通過跡に一部の排水が留まり、乾燥して汚れ成分がこびり付くようにして残る。汚れの性質は排水の内容によって変化するが、髪の毛や垢などの成分、油分、洗剤成分等を含んでいる場合が多く、このような汚れ部分に雑菌が繁殖し、非衛生的で有ると共に、異臭を生じたりする、という問題が生じる。前述のように排水が洗濯機用防水パンの内部を流れることは希で、排水が繰り返し流れ込むこともほとんど無いため、後から流れ込む排水が、前の排水の汚れを洗い流す、という事もない。従って、洗濯機用防水パン内部に排水が生じた場合は、洗濯機用防水パン内部の清掃を行う必要がある。
この内、洗濯機や洗濯機用ホースが故障・破損し洗濯機用防水パンの内部に排水が漏出した場合は、修理のため洗濯機自体を移動させる必要性が生じるから、洗濯機を移動させ上方に障害物が無くなった洗濯機用防水パンの内部を清掃することに支障は生じない。
一方、特許文献1に記載の洗濯機用防水パンと排水トラップにおいて、清掃のため封水椀等の排水トラップの部材を取り出す場合、洗濯機を洗濯機用防水パン上に載置した状態で行うこととなる(元々、特許文献1の発明は、洗濯機用防水パンの上方に洗濯機を配置した状態のまま、排水トラップの部材を取り出し、清掃するための発明である)。
通常洗濯機用防水パンの内部は、排水トラップを取り付ける開口部に向かって下るように勾配を設定されるが、この勾配は極めて緩やかなため、排水の流れ方はこの勾配よりも封水椀の倒し方に強く影響を受ける。封水椀の倒し方はその時の状況に応じてまちまちだから、洗濯機用防止パン内部の排水がどの様に流れたかもまちまちであり、排水の広がり方は安定しない。洗濯機用防水パンの内部は床面すれすれの極めて低い位置に配置され、更に洗濯機に覆われて内部を視認し難いため、排水が流れた汚れ部分を確認し、汚れ部分のみを選択的に清掃するのは困難である。従って確実な清掃を行うためには、排水で汚れている部分、汚れていない部分に関係なく、洗濯機用防水パンの内部全てを清掃する、等の方法を取らざるを得ない。しかし、洗濯機の下端と洗濯機用防水パンの内部との空間は狭く、この狭隘な空間にて、洗濯機下端と洗濯機用防水パンの周壁上端との間の狭い隙間から手を差し込んで、洗濯機用防水パンの内部全てを清掃することは、極めて困難な作業である。
またホースなどを利用し水道水などを洗濯機用防水パンの内部に流して、排水の汚れを洗い流す方法も考えられるが、これもホースの向きなどによって周壁の上を超えて水道水が溢れ、洗濯機用防水パンの周壁の外側の床面に染みや破損などのダメージを与えたり、洗濯機の下面に水道水が掛かって洗濯機の故障の原因となることが考えられるため、好適な方法とは言えない。
本発明は上記問題点に鑑み発明されたものであって、清掃の際に、洗濯機用防水パンの底面上を汚すことなく、排水トラップの部材の清掃を容易に行うことができる、洗濯機用防水パンと排水トラップを提供するものである。
In the case of the waterproof pan for a washing machine and the drain trap described in Patent Document 1 as described above, there are problems as described below.
In ordinary washing machine waterproof pans including the washing machine waterproof pan described in Patent Document 1, there is virtually no drainage inside the washing machine waterproof pan, such as on the inner surface or bottom surface of the peripheral wall.
This is because in a situation where the washing machine is used without any trouble, the wastewater from the washing machine flows directly into the drain trap, and the drainage does not flow inside the waterproof pan for the washing machine, particularly on the bottom surface.
If drainage flows inside the waterproof pan for washing machines, it is extremely rare that the washing machine or washing machine hose breaks down or breaks down and the drainage leaks into the waterproof pan for washing machines, or as described in paragraph 0005 As described above, when taking out the sealing water bottle at the time of cleaning, it is limited to any case where the sealing water tank is laid down and the internal drainage flows out.
The waterproof pan for washing machines is a component premised on the treatment of wastewater, and it is molded with a resin material. Unlike the case where the wastewater overflows on the normal floor surface, even if the wastewater flows into the interior, it cannot be repaired. It is possible to discharge the waste water to the sewage side without causing a problem such as a stain or damage. However, if the wastewater flows down inside the waterproof pan for a washing machine and is left as it is, a part of the wastewater stays on the passage of the wastewater, and remains so that the dirt component sticks to dryness. The nature of the dirt changes depending on the contents of the drainage, but it often contains ingredients such as hair and dirt, oil, detergent ingredients, etc., and germs grow on these dirt parts and are unsanitary, There is a problem that a strange odor is generated. As described above, the wastewater rarely flows inside the waterproof pan for a washing machine, and the wastewater hardly flows repeatedly. Therefore, the wastewater that flows later does not wash away the dirt of the previous wastewater. Accordingly, when drainage occurs inside the waterproof pan for the washing machine, it is necessary to clean the inside of the waterproof pan for the washing machine.
Of these, if the washing machine or washing machine hose breaks down or breaks down and drainage leaks into the waterproof pan for washing machine, it will be necessary to move the washing machine for repair. There is no problem in cleaning the inside of the waterproof pan for a washing machine with no obstacles above.
On the other hand, in the waterproof pan and drain trap for a washing machine described in Patent Document 1, when a drain trap member such as a sealing tub is taken out for cleaning, the washing machine is placed on the waterproof pan for the washing machine. (Originally, the invention of Patent Document 1 is an invention for taking out and cleaning the drain trap member while the washing machine is disposed above the waterproof pan for washing machine).
Normally, the inside of a waterproof pan for a washing machine is graded so that it goes down toward the opening where the drain trap is installed, but since this slope is extremely gentle, the direction of drainage flows more than the slope. Strongly influenced by how to kill. Since the method of depressing the sealing jar varies depending on the situation at that time, it depends on how the drainage inside the washing pan for the washing machine flows, and the spreading of the drainage is not stable. The inside of the waterproof pan for the washing machine is placed at a position where the floor surface is extremely low, and it is also difficult to see the inside because it is covered with the washing machine, so check the dirty part where drainage has flowed, and select only the dirty part It is difficult to clean. Therefore, in order to perform reliable cleaning, it is necessary to take a method such as cleaning the entire interior of the waterproof pan for a washing machine, regardless of whether it is dirty or not. However, the space between the lower end of the washing machine and the inside of the waterproof pan for the washing machine is narrow, and in this narrow space, insert your hand through the narrow gap between the lower end of the washing machine and the upper peripheral wall of the waterproof pan for the washing machine. Cleaning the entire inside of the waterproof pan for a washing machine is an extremely difficult task.
You can also use a hose to drain tap water, etc., inside the waterproof pan for the washing machine to wash away dirt from the drainage, but this also causes the tap water to overflow over the peripheral wall depending on the direction of the hose, etc. A suitable method because it may cause damage such as stains or damage to the floor surface outside the peripheral wall of the waterproof pan for washing machines, or it may cause tap water on the lower surface of the washing machine and cause malfunction of the washing machine. It can not be said.
The present invention has been invented in view of the above-described problems, and is capable of easily cleaning a drain trap member without soiling the bottom surface of a waterproof pan for a washing machine during cleaning. A waterproof pan and drain trap are provided.

上記のように構成された洗濯機用防水パンと排水トラップは、以下のように施工される。尚、特に記載しないが、以下の施工の際、水密的な接続が要求される部分には、必要に応じて接着やパッキングを利用したネジ接続などにより、水密的に接続される。
まず床面Fにトラップ本体9を配置するための開口を設ける。次に、この開口を通してトラップ本体9の排出口9aを下水側配管に接続する。更に、フランジ部材10の筒体部分13aを開口部2aに挿通し、段押し部2bの上面にフランジ部材10のフランジ部10aを収納した上で、フランジ部材10の雄ネジを、トラップ本体9の雌ネジに螺合させる。これにより、フランジ部材10のフランジ部10a下面と、トラップ本体9の凸部9b上面とで、洗濯機用防水パン1の開口部2aの周縁、即ち段押し部2bの底面2を挟持するようにして、トラップ本体9とフランジ部材10が、洗濯機用防水パン1に固定される。
更に床面F上に洗濯機用防水パン1を、ビスなどを使用して固定する。
この時、本実施例では、前述のように、段押し部2bの裏面の下端と、外側の周壁3の下端との上下方向の位置関係については、段押し部2bの裏面の下端の方が、少なくともトラップ本体9の凸部9bの上下方向の厚み分以上の幅を有して上方となるように構成されてなるため、床面Fに排水トラップTを配置するために設ける開口は、トラップ本体9の凸部9bを除く側面形状にのみ合わせて開口するだけで良い物となる。
簡単に説明すると、床面Fの開口と凸部9bの周縁との間に隙間が広く設けられていたり、凸部9bの下方に床面Fが存在しない状態であると、床下空間の通気などが凸部9bの隙間から洩れ、屋内側に不要な通気を生じて居住者に不快感を与えてしまう、等の問題を生じる。これを防止するために、従来例の場合、床面Fの開口は、トラップ本体9の側面の開口に、更に凸部9bの周縁の開口に合わせて段を設ける二段形状にしなければならなかった。しかし、本第一実施例では、凸部9bが床面Fに食い込むことが無くなったため、床面Fを、トラップ本体9の側面形状にのみ合わせて開口するだけで良くなり、作業が簡易となった分、作業性を良い物とすることができる(側面に設けた排出口に対応するため、部分的に大きく切り拡げ、トラップ本体を取り付けた後に板材で余計な開口部分を塞ぐ場合があるが、図1では省略する)。
The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body 9 is provided on the floor surface F. Next, the discharge port 9a of the trap body 9 is connected to the sewage side pipe through this opening. Further, the tubular portion 13a of the flange member 10 is inserted into the opening 2a, and the flange portion 10a of the flange member 10 is accommodated on the upper surface of the stepped portion 2b. Screw onto the female screw. Accordingly, the lower surface of the opening 2a of the waterproof pan 1 for a washing machine, that is, the bottom surface 2 of the stepped portion 2b is sandwiched between the lower surface of the flange portion 10a of the flange member 10 and the upper surface of the convex portion 9b of the trap body 9. Thus, the trap body 9 and the flange member 10 are fixed to the waterproof pan 1 for a washing machine.
Further, the waterproof pan 1 for a washing machine is fixed on the floor surface F using screws or the like.
At this time, in this embodiment, as described above, regarding the vertical positional relationship between the lower end of the back surface of the step pressing portion 2b and the lower end of the outer peripheral wall 3, the lower end of the back surface of the step pressing portion 2b is The opening provided for disposing the drainage trap T on the floor F has a width equal to or greater than the thickness of the convex portion 9b of the trap body 9 in the vertical direction. It becomes a thing which only needs to open according to the side shape except the convex part 9b of the main body 9.
Briefly, if there is a wide gap between the opening of the floor surface F and the peripheral edge of the convex portion 9b, or if the floor surface F does not exist below the convex portion 9b, ventilation in the underfloor space, etc. Leaks from the gap between the convex portions 9b, causing unnecessary ventilation on the indoor side and causing the occupant to feel uncomfortable. In order to prevent this, in the case of the conventional example, the opening of the floor surface F must be formed in a two-stage shape in which a step is provided in accordance with the opening on the side surface of the trap body 9 and the opening on the peripheral edge of the convex portion 9b. It was. However, in the first embodiment, since the convex portion 9b does not bite into the floor surface F, it is only necessary to open the floor surface F according to the side surface shape of the trap body 9, and the operation is simplified. Therefore, workability can be improved (in order to correspond to the discharge port provided on the side surface, it may be partially enlarged and expanded, and after installing the trap body, the extra opening may be blocked with a plate material. , Omitted in FIG. 1).

次に、フランジ部材10内部につり下げるようにして、封水椀12をトラップ本体9内部に配置すると共に、洗濯機用接続管16を内部に収納した防臭筒13の、上端のすり鉢状部分の外周部分を、フランジ部材10内面に対して水密的に接続する。
これにより、洗濯機用接続管16は、T字を上下逆転した状態にて、また、水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するようにして、排水トラップT内部に取り付けることができる。
この状態で、フランジ部材10の内部の開口が、排水口10bとして機能する。更に排水口10bに目皿部材11をセットし、エルボ管E等を利用し洗濯機用接続管16に洗濯機用排水ホースを接続した上で、足置き台4上に洗濯機の脚部を載置する。最後に、凹部5に壁部材8を水密的に取り付けて、洗濯機用防水パンと排水トラップ、及び洗濯機の施工が完了する。
Next, the sealing tub 12 is disposed inside the trap body 9 so as to hang inside the flange member 10 and the mortar-shaped portion of the upper end of the deodorizing cylinder 13 housing the washing machine connection pipe 16 therein. The outer peripheral portion is watertightly connected to the inner surface of the flange member 10.
As a result, the connecting pipe 16 for the washing machine is in a state in which the T-shape is turned upside down, and the ends of the horizontal tube part are slightly outside the outer surface of the cylinder part 13a of the deodorizing cylinder 13 at both ends. Can be attached to the inside of the drain trap T.
In this state, the opening inside the flange member 10 functions as the drain port 10b. Further, the eye plate member 11 is set in the drain port 10b, and the washing machine drain hose is connected to the washing machine connection pipe 16 by using the elbow pipe E or the like. Place. Finally, the wall member 8 is watertightly attached to the recess 5 to complete the construction of the waterproof pan for the washing machine, the drain trap, and the washing machine.

上記のように構成された洗濯機用防水パンと排水トラップは、以下のようにして使用される。
洗濯機Lを使用し、洗濯機Lより排水が生じると、洗濯機Lからの排水は、洗濯機用排水ホースから、洗濯機用接続管16を介し、封水椀12内部に流入して溜まり、充分に溜まると封水椀12の側面に設けられた開口から溢れ出す。封水椀12から流出した排水は、トラップ本体9内部から排出口9aを介して下水側に排出される。この際、洗濯機用接続管16の水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するように構成されてなるため、洗濯機Lからの泡混じりの排水は、まず防臭筒13の筒体部分13aの外部にのみ排出され、防臭筒13の内部には排出されない。そして排水中の泡はその浮力により排水に対して浮き上がるから、防臭筒13の筒体部分13aの外部に排出された排水中の泡はそのまま防臭筒13外側面と封水椀12内側面の間を通過し、封水椀12側面の開口から下流側に排出され、防臭筒13内面から排水口10bに逆流することは無い。
また、洗濯機L自体や洗濯機用排水ホースの破損等により、洗濯機用防水パン1の底面2上に排水が生じると、排水は、少なくとも洗濯機用防水パン1の段部6の底面2上を通過した上で、排水口10bの目皿部材11を通過し、防臭筒13内部、封水椀12内部、封水椀12の上方の開口、トラップ本体9内部、排出口9a、の順に通過し、最終的に下水側に排出される。
尚、周壁3の凹部5には、壁部材8が水密的に取り付けられているため、洗濯機用防水パン1内部に排水が生じても、周壁3の上端にまで排水が溜まらない限り、排水が洗濯機用防水パン1内部より溢れ出る事はない。
また、上記のように構成した排水トラップTにおいて、洗濯機用接続管16又は排水口10bを介し、排水トラップT内に排水が行われると、封水椀12内部に、側面の開口の下端の高さまで排水が溜まる。これにより、排水口10b又は洗濯機用接続管16から封水椀12の側面の開口部2a下端までの流路に、排水で満たされた部分が形成される。この溜まった排水を封水と呼び、下水側から臭気や害虫類が屋内側に侵入しようとしても、この封水によってそれ以上屋内側に侵入されることを防止ることができる。このように、下水側から臭気や害虫類が屋内側に侵入することを防止する機能をトラップ機能と呼ぶ。
The washing machine waterproof pan and drain trap configured as described above are used as follows.
When the washing machine L is used and drainage is generated from the washing machine L, the drainage from the washing machine L flows from the washing machine drain hose through the washing machine connection pipe 16 into the sealed water bottle 12 and accumulates. When it is sufficiently collected, it overflows from the opening provided on the side surface of the sealing tub 12. The waste water that has flowed out of the sealing tub 12 is discharged from the inside of the trap body 9 to the sewage side through the discharge port 9a. At this time, since the ends of the horizontal tube portion of the connecting pipe 16 for the washing machine are configured so that both ends protrude slightly outward from the outer surface of the tube portion 13a of the deodorizing tube 13, the washing machine The bubble-mixed waste water from L is first discharged only to the outside of the cylindrical portion 13 a of the deodorizing cylinder 13 and is not discharged to the inside of the deodorizing cylinder 13. Since the bubbles in the drainage are lifted with respect to the drainage by the buoyancy, the bubbles in the drainage discharged to the outside of the cylindrical portion 13a of the deodorizing cylinder 13 are directly between the outer surface of the deodorizing cylinder 13 and the inner surface of the sealing tub 12. And is discharged downstream from the opening on the side surface of the sealing tub 12 and does not flow backward from the inner surface of the deodorizing cylinder 13 to the drain port 10b.
Further, if drainage occurs on the bottom surface 2 of the washing machine waterproof pan 1 due to damage to the washing machine L itself or the washing machine drain hose, etc., the drainage is at least the bottom surface 2 of the step portion 6 of the washing machine waterproof pan 1. After passing through the top, it passes through the eye plate member 11 of the drainage port 10b, and in the order of the inside of the deodorizing cylinder 13, the inside of the sealing tub 12, the opening above the sealing tub 12, the inside of the trap body 9, and the discharge port 9a. Passes through and is finally discharged to the sewage side.
In addition, since the wall member 8 is watertightly attached to the recess 5 of the peripheral wall 3, even if drainage occurs inside the waterproof pan 1 for a washing machine, as long as the drainage does not accumulate at the upper end of the peripheral wall 3, Does not overflow from the inside of the waterproof pan 1 for a washing machine.
Further, in the drain trap T configured as described above, when drainage is performed in the drain trap T via the washing machine connection pipe 16 or the drain port 10b, the bottom end of the side opening is placed inside the sealing tub 12. Drainage collects up to the height. Thus, a portion filled with drainage is formed in the flow path from the drain outlet 10b or the connecting pipe 16 for the washing machine to the lower end of the opening 2a on the side surface of the sealing tub 12. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

上記のように構成した第一実施例の洗濯機用防水パンと排水トラップにおいて、長期間の使用により、排水トラップT内部に汚れが付着して異臭を生じたり、堆積した毛髪や糸くず等の塵芥、汚れ成分などで管詰まりが生じ、排水トラップTの内部を清掃する必要が生じた場合、以下の方法にて排水トラップTの部材を取り出し、清掃することができる。
まず凹部5から壁部材8を取り外し、周壁3内部に作業者の手を挿入できる隙間空間を確保する。
次に、切り欠きを拡径して、洗濯機用接続管16又は洗濯機用排水ホースから目皿部材11を取り外し、段部6、凹部5を介して周壁3の外部に取り出す。
次に、洗濯機用接続管16と洗濯機用排水ホースとの接続を解除した上で、防臭筒13とフランジ部材10との接続を解除する。
その後、防臭筒13、洗濯機用接続管16、封水椀12をそれぞれ周壁3の外部に取り出す。
この排水トラップTの部材の取り出し作業に際して、清掃作業の作業者は、防臭筒13、封水椀12等の各部材を取り出す際、以下に記載した理由1.乃至理由3.の理由により、底部の開口部2a(本実施例の場合にはフランジ部材10内部の排水口10b)より防臭筒13、封水椀12をそれぞれ上方に取り出し、そのまま傾斜させることなく水平に移動させて、図8に示したように凹部5より取り出し作業を行う事となる。よって、段部6以外の底面2上に封水椀12内の封水(排水)がこぼれることがほぼ確実に無くなる。
理由1.本実施例においては、封水椀12の縦幅は封水椀12の横幅よりも短く、また防臭筒13の縦幅は封水椀12の横幅よりも短くなるように構成してなるため、従来例のように、封水椀12や防臭筒13(特に封水椀12)を傾斜させることにメリットは無く、傾斜させずに水平に移動させて周壁3から取り出す方が好適になるように構成してなる。
理由2.上記清掃作業において、段部6はガイドとして機能し、防臭筒13、封水椀12等の部材が横方向に傾斜するのを防ぐ効果を奏する。
理由3.封水椀12、防臭筒13、及び凹部5の各下端部分を、側面視略水平状となるように構成してなる。これにより、封水椀12、防臭筒13を凹部5から取り出す際、封水椀12、防臭筒13を傾斜することなく取り出すガイドとして機能し、防臭筒13、封水椀12等の部材が横方向に傾斜するのを防ぐ効果を奏する。
In the waterproof pan and drainage trap for the washing machine of the first embodiment configured as described above, due to long-term use, dirt adheres to the inside of the drainage trap T, and a strange odor is produced, such as accumulated hair and lint. When pipe clogging occurs due to dust, dirt components, etc., and it becomes necessary to clean the inside of the drain trap T, the member of the drain trap T can be taken out and cleaned by the following method.
First, the wall member 8 is removed from the recess 5 to secure a clearance space in which the operator's hand can be inserted into the peripheral wall 3.
Next, the diameter of the notch is expanded, the eye plate member 11 is removed from the washing machine connecting pipe 16 or the washing machine drain hose, and taken out to the outside of the peripheral wall 3 through the step 6 and the recess 5.
Next, the connection between the washing machine connection pipe 16 and the washing machine drain hose is released, and then the connection between the deodorizing cylinder 13 and the flange member 10 is released.
Thereafter, the deodorizing cylinder 13, the washing machine connection pipe 16, and the water seal 12 are taken out of the peripheral wall 3.
When the member of the drain trap T is taken out, the cleaning operator takes the following reasons when taking out the members such as the deodorizing cylinder 13 and the water seal 12. To reason 3 For this reason, the deodorizing cylinder 13 and the water seal 12 are taken out from the opening 2a at the bottom (in the case of this embodiment, the drain port 10b inside the flange member 10) and moved horizontally without being inclined. Thus, as shown in FIG. Therefore, it is almost certainly eliminated that the sealed water (drainage) in the sealed water bottle 12 is spilled on the bottom surface 2 other than the step portion 6.
Reason 1. In this embodiment, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, and the vertical width of the deodorizing cylinder 13 is configured to be shorter than the horizontal width of the sealed water jar 12, As in the conventional example, there is no merit in inclining the sealed water bottle 12 or the deodorizing cylinder 13 (especially the sealed water bottle 12), and it is preferable to move it horizontally without being inclined and take it out from the peripheral wall 3. Consists of.
Reason 2 In the cleaning operation, the step portion 6 functions as a guide, and has an effect of preventing members such as the deodorizing cylinder 13 and the water seal 12 from being inclined in the lateral direction.
Reason 3. The bottom ends of the water seal 12, the deodorizing cylinder 13, and the recess 5 are configured to be substantially horizontal when viewed from the side. Thereby, when taking out the sealing water bottle 12 and the deodorizing cylinder 13 from the recessed part 5, it functions as a guide which takes out the sealing water bottle 12 and the deodorizing cylinder 13 without inclining, and members, such as the deodorizing cylinder 13 and the sealing water bottle 12, are sideways. There is an effect of preventing tilting in the direction.

更に本実施例では、段部6以外の底面2から足置き台4上端までの高さ幅を封水椀12及び防臭筒13の高さ幅より狭くすることで、段部6以外の底面2上に封水椀12及び防臭筒13を移動させることが不可能に構成している。これにより、段部6以外の底面2上に封水椀12内の封水(排水)がこぼれることが確実に無くなる。また万一封水をこぼしてしまった場合でも、封水は凹部5に連通する段部6上にのみこぼれるため、清掃が必要な箇所は、視認し易く且つ作業者が手を差し込みやすい凹部5及び段部6のみに限定され、清掃が極めて容易である。   Furthermore, in this embodiment, the bottom surface 2 other than the step portion 6 is made smaller by making the height width from the bottom surface 2 other than the step portion 6 to the upper end of the footrest 4 smaller than the height width of the sealing jar 12 and the deodorizing cylinder 13. It is impossible to move the water seal 12 and the deodorizing cylinder 13 upward. Thereby, it is surely prevented that the sealed water (drainage) in the sealed water bottle 12 is spilled on the bottom surface 2 other than the step portion 6. Even if the spilled water is spilled, the sealed water is spilled only on the stepped portion 6 communicating with the recessed portion 5, so that the portion that needs to be cleaned is easily visible and the operator can easily insert the hand into the recessed portion 5. And it is limited only to the step part 6, and cleaning is very easy.

このようにして排水トラップTから部材を取り出し、清掃を行った後、また場合によってはトラップ本体9内部の清掃や、排出口9aから下流側の配管の清掃作業/管詰まりの解消を、機材などを凹部5また排水口10bを介して作業を行い、清掃作業/管詰まりの解消を行った後、段落0021に記載の、洗濯機Lを洗濯機用防水パン1に載置する以外の作業を繰り返すことで、排水トラップTの部材の取り付け作業を完了させ、排水トラップTの清掃作業が完了する。 After removing the member from the drain trap T and cleaning it in this way, in some cases, cleaning the inside of the trap body 9 or cleaning the pipe downstream from the discharge port 9a / resolving clogging of the equipment, etc. After carrying out the work through the recess 5 and the drain port 10b to perform the cleaning work / clogging of the tube, the work other than placing the washing machine L on the waterproof pan 1 for the washing machine described in paragraph 0021 is performed. By repeating, the attachment operation | work of the member of the drain trap T is completed, and the cleaning operation | work of the drain trap T is completed.

封水椀12は、有底筒状にして、上方上面、及び側面上方に開口を備えてなる。またこの封水椀12は、上方部分が、施工時フランジ部材10内部につり下げられるように構成される。
防臭筒13は略円筒状の部材であって、上方部分は、上に行くほど拡径するすり鉢形状を成すすように構成される。また、施工完了時、上端部分は排水口10bに水密的に接続されると共に、下端部分は封水椀12内部であって、封水椀12の側面の開口の下端よりも下方に配置される。
更に本実施例においては、すり鉢形状部分の下面に、封水椀12の側面の開口と係合するツメ部13bを備えてなる。このツメ部13bは封水椀12に対し若干の遊びを有した状態で係合するものであって、施工完了時、封水椀12はフランジ部材10内部につり下げられ、防臭筒13のツメ部13bに対しては浮いた状態に配置される。但し、清掃時等防臭筒13とフランジ部材10との水密的な接続を解除された際、防臭筒13を上方に引き上げると、そのままツメ部13bにて係合された封水椀12を引き上げることができる。
洗濯機用接続管16は、略T字形状に分岐した管体であって、施工時にはT字を上下逆転した状態にて、垂直な管体部分は防臭筒13の筒体部分13aの内部に、水平な管体部分は防臭筒13下端と封水椀12の下壁上面との間に配置される(水平な管体部分は偏平につぶされたような形状を成す)。また、水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するように構成されてなる。施工時、このように構成された洗濯機用接続管16の内、中央の垂直な管体の上端は、洗濯機Lからの排水を排出する洗濯機用排水ホースに接続され、洗濯機Lからの排水を、防臭筒13の外側であって、封水椀12の内部に排出する。尚、施工完了時、洗濯機用接続管16の内、中央の垂直な管体、及び封水椀12、防臭筒13は、同心円状に配置される。
目皿部材11は排水口10bに配置される部材であって、中央部分に洗濯機用接続管16を通す開口を設けると共に、周囲部分には複数の孔を設けて、洗濯機用防水パン1上に排水が生じた場合に、排水中の毛髪や大きなゴミを分離・捕集するように構成されてなる。目皿部材11には周縁から中央の開口まで開口する切り欠きが形成されてなり、目皿部材11の弾性を利用し、該切り欠きを押し広げる事で、洗濯機用接続管16と洗濯機用排水ホースとの接続を解除することなく、目皿部材11を取り出すことができる。
尚、上記各部材の内、封水椀12、防臭筒13、及び洗濯機用接続管16の下端部分は、側面視略水平状となるように構成してなる。前述のように、ここでいう「水平状」とは施工及び各部材の取り付けが完了した状態において、側面視水平面に平行となるような形状に形成されていることを指し示す表現であり、単に「平坦面」を指し示すものでは無い。また、厳密には防臭筒13の下端部分は筒形状であって「面」ではないが、これは筒形状の下端部分を連続することで形成される、仮想的な平坦面が、施工及び各部材の取り付けが完了した状態において、側面視水平面に平行となるような面であることを指し示すものである。
また、封水椀12の縦幅は封水椀12の横幅よりも短く、また防臭筒13の縦幅は封水椀12の横幅よりも短くなるように構成してなる。
更に本実施例では、このように、防臭筒13と封水椀12をツメ部13bにて係合することで、図20に示したような、防臭筒13と封水椀12とで封水ユニット14を構成する。この封水ユニット14の状態では、防臭筒13が封水椀12の蓋をするような位置に配置されるため、封水椀12内部の封水(排水)がこぼれ出ることをより確実に防止することができる。
また、この封水ユニット14の状態においても、封水ユニット14の縦幅は、封水ユニット14の横幅よりも短くなるように構成されてなる。
更に、接続管付き封水ユニット15の状態では、洗濯機用排水接続管が防臭筒13よりも若干上方に突出するように構成されてなる。この封水ユニット14に洗濯機用排水接続管を組み合わせた状態における、洗濯機用排水接続管の上端から封水椀12の下端までの縦幅は、凹部5下端から、足置き台4上端までの高さ幅よりも幅狭となるように構成してなる。
また、前述のように防臭筒13と封水椀12の内部には洗濯機用接続管16が収納されてなり、洗濯機用接続管16の水平な管体部分の端部が、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するように構成されている。このため、洗濯機用接続管16の中央の垂直な管体を摘むようにし、そのまま上方に引き上げると、洗濯機用接続管16の水平な管体部分の両端に防臭筒13が載架した状態となり(水平な管体部分は偏平につぶされたような形状を成すため、上面が平坦であることも、洗濯機用接続管16の水平な管体部分の両端に防臭筒13が安定した状態で載架するために有効に作用する)、且つツメ部13b材により防臭筒13と封水椀12が係合した状態であることから、接続管付き封水ユニット15を水平状体を維持したまま容易に引き上げることができる。
また、洗濯機用防水パン1上に配置される洗濯機Lは、略箱体を成す排水機器(使用により排水を生じる機器)であって、側面に洗濯物などの投入口を有すると共に、下方に4つの脚部を有し、また洗濯機Lの使用により生じた、洗剤や汚れ成分を含んだ排水を排出するための洗濯機用排水ホース(端部となるエルボ管Eのみ図示)を備えてなる。

上記のように構成された洗濯機用防水パンと排水トラップは、以下のように施工される。尚、特に記載しないが、以下の施工の際、水密的な接続が要求される部分には、必要に応じて接着やパッキングを利用したネジ接続などにより、水密的に接続される。
まず床面Fにトラップ本体9を配置するための開口を設ける。次に、この開口を通してトラップ本体9の排出口9aを下水側配管に接続する。更に、フランジ部材10の筒体部分13aを開口部2aに挿通し、段押し部2bの上面にフランジ部材10のフランジ部10aを収納した上で、フランジ部材10の雄ネジを、トラップ本体9の雌ネジに螺合させる。これにより、フランジ部材10のフランジ部10a下面と、トラップ本体9の凸部9b上面とで、洗濯機用防水パン1の開口部2aの周縁、即ち段押し部2bの底面2を挟持するようにして、トラップ本体9とフランジ部材10が、洗濯機用防水パン1に固定される。
更に床面F上に洗濯機用防水パン1を、ビスなどを使用して固定する。
この時、本実施例では、前述のように、段押し部2bの裏面の下端と、外側の周壁3の下端との上下方向の位置関係については、段押し部2bの裏面の下端の方が、少なくともトラップ本体9の凸部9bの上下方向の厚み分以上の幅を有して上方となるように構成されてなるため、床面Fに排水トラップTを配置するために設ける開口は、トラップ本体9の側面形状にのみ合わせて開口するだけで良い物となる。
簡単に説明すると、床面Fの開口と凸部9bの周縁との間に隙間が広く設けられていたり、凸部9bの下方に床面Fが存在しない状態であると、床下空間の通気などが凸部9bの隙間から洩れ、屋内側に不要な通気を生じて居住者に不快感を与えてしまう、等の問題を生じる。これを防止するために、従来例の場合、床面Fの開口は、トラップ本体9の側面に、更に凸部9bの周縁の開口に合わせて段を設ける二段形状にしなければならなかった。しかし、本第二実施例では、凸部9bが床面Fに食い込むことが無くなったため、床面Fを、トラップ本体9の凸部9bを除く側面形状にのみ合わせて開口するだけで良くなり、作業が簡易となった分、作業性を良い物とすることができる(側面に設けた排出口に対応するため、部分的に大きく切り拡げ、トラップ本体を取り付けた後に板材で余計な開口部分を塞ぐ場合があるが、図9では省略する)。
The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body 9 is provided on the floor surface F. Next, the discharge port 9a of the trap body 9 is connected to the sewage side pipe through this opening. Further, the tubular portion 13a of the flange member 10 is inserted into the opening 2a, and the flange portion 10a of the flange member 10 is accommodated on the upper surface of the stepped portion 2b. Screw onto the female screw. Accordingly, the lower surface of the opening 2a of the waterproof pan 1 for a washing machine, that is, the bottom surface 2 of the stepped portion 2b is sandwiched between the lower surface of the flange portion 10a of the flange member 10 and the upper surface of the convex portion 9b of the trap body 9. Thus, the trap body 9 and the flange member 10 are fixed to the waterproof pan 1 for a washing machine.
Further, the waterproof pan 1 for a washing machine is fixed on the floor surface F using screws or the like.
At this time, in this embodiment, as described above, regarding the vertical positional relationship between the lower end of the back surface of the step pressing portion 2b and the lower end of the outer peripheral wall 3, the lower end of the back surface of the step pressing portion 2b is The opening provided for disposing the drainage trap T on the floor F has a width equal to or greater than the thickness of the convex portion 9b of the trap body 9 in the vertical direction. It is sufficient to open only in accordance with the side shape of the main body 9.
Briefly, if there is a wide gap between the opening of the floor surface F and the peripheral edge of the convex portion 9b, or if the floor surface F does not exist below the convex portion 9b, ventilation in the underfloor space, etc. Leaks from the gap between the convex portions 9b, causing unnecessary ventilation on the indoor side and causing the occupant to feel uncomfortable. In order to prevent this, in the case of the conventional example, the opening of the floor surface F has to be formed in a two-stage shape in which a step is provided on the side surface of the trap body 9 in accordance with the opening on the periphery of the convex portion 9b. However, in the second embodiment, since the convex portion 9b does not bite into the floor surface F, it is only necessary to open the floor surface F according to only the side surface shape excluding the convex portion 9b of the trap body 9, Since the work is simplified, workability can be improved (to accommodate the discharge port provided on the side surface, it is partially enlarged, and after installing the trap body, an extra opening is made with a plate. (It is not shown in FIG.

次に、防臭筒13と封水椀12の内部に洗濯機用接続管16を収納した状態で、防臭筒13と封水椀12をツメ部13bにて係合させたことで構成した、接続管付き封水ユニット15を、フランジ部材10の開口部2aから挿通する。この後、封水椀12をフランジ部材10内部につり下げるようにして、トラップ本体9内部に配置すると共に、洗濯機用接続管16を内部に収納した防臭筒13の、上端のすり鉢状部分の外周部分を、フランジ部材10内面に対して水密的に接続する。
これにより、洗濯機用接続管16は、T字を上下逆転した状態にて、また、水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するようにして、排水トラップT内部に取り付けることができる。
この状態で、フランジ部材10の内部の開口が、排水口10bとして機能する。更に排水口10bに目皿部材11をセットし、エルボ管E等を利用し洗濯機用接続管16に洗濯機用排水ホースを接続した上で、足置き台4上に洗濯機Lの脚部を載置する。最後に、凹部5に壁部材8を水密的に取り付けて、洗濯機用防水パンと排水トラップ、及び洗濯機の施工が完了する。
Next, the connection configured by engaging the deodorizing cylinder 13 and the sealing water bottle 12 with the claw portion 13b in a state where the washing machine connection pipe 16 is housed inside the deodorizing cylinder 13 and the sealing water bottle 12. The sealed water unit 15 with a pipe is inserted through the opening 2 a of the flange member 10. Thereafter, the sealing tub 12 is suspended inside the flange member 10 so as to be disposed inside the trap body 9 and the mortar-shaped portion at the upper end of the deodorizing cylinder 13 housing the connecting pipe 16 for the washing machine inside. The outer peripheral portion is watertightly connected to the inner surface of the flange member 10.
As a result, the connecting pipe 16 for the washing machine is in a state in which the T-shape is turned upside down, and the ends of the horizontal tube part are slightly outside the outer surface of the cylinder part 13a of the deodorizing cylinder 13 at both ends. Can be attached to the inside of the drain trap T.
In this state, the opening inside the flange member 10 functions as the drain port 10b. Further, the eye plate member 11 is set in the drain port 10b, and the washing machine drain hose is connected to the washing machine connection pipe 16 using the elbow pipe E or the like, and the leg of the washing machine L is placed on the footrest 4. Is placed. Finally, the wall member 8 is watertightly attached to the recess 5 to complete the construction of the waterproof pan for the washing machine, the drain trap, and the washing machine.

上記のように構成された洗濯機用防水パンと排水トラップは、以下のようにして使用される。
洗濯機Lを使用し、洗濯機Lより排水が生じると、洗濯機Lからの排水は、洗濯機用排水ホースから、洗濯機用接続管16を介し、封水椀12内部に流入して溜まり、充分に溜まると封水椀12の側面に設けられた開口から溢れ出す。封水椀12から流出した排水は、トラップ本体9内部から排出口9aを介して下水側に排出される。この際、洗濯機用接続管16の水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するように構成されてなるため、洗濯機Lからの泡混じりの排水は、まず防臭筒13の筒体部分13aの外部にのみ排出され、防臭筒13の内部には排出されない。そして排水中の泡はその浮力により排水に対して浮き上がるから、防臭筒13の筒体部分13aの外部に排出された排水中の泡はそのまま防臭筒13外側面と封水椀12内側面の間を通過し、封水椀12側面の開口から下流側に排出され、防臭筒13内面から排水口10bに逆流することは無い。
また、洗濯機L自体や洗濯機用排水ホースの破損等により、洗濯機用防水パン1の底面2上に排水が生じると、排水は、洗濯機用防水パン1の底面2上を通過した上で、排水口10bの目皿部材11を通過し、防臭筒13内部、封水椀12内部、封水椀12の上方の開口、トラップ本体9内部、排出口9a、の順に通過し、最終的に下水側に排出される。
尚、周壁3の凹部5には、壁部材8が水密的に取り付けられているため、洗濯機用防水パン1内部に排水が生じても、周壁3の上端にまで排水が溜まらない限り、排水が洗濯機用防水パン1内部より溢れ出る事はない。
また、上記のように構成した排水トラップTにおいて、洗濯機用接続管16又は排水口10bを介し、排水トラップT内に排水が行われると、封水椀12内部に、側面の開口の下端の高さまで排水が溜まる。これにより、排水口10b又は洗濯機用接続管16から封水椀12の側面の開口部2a下端までの流路に、排水で満たされた部分が形成される。この溜まった排水を封水と呼び、下水側から臭気や害虫類が屋内側に侵入しようとしても、この封水によってそれ以上屋内側に侵入されることを防止ることができる。このように、下水側から臭気や害虫類が屋内側に侵入することを防止する機能をトラップ機能と呼ぶ。
The washing machine waterproof pan and drain trap configured as described above are used as follows.
When the washing machine L is used and drainage is generated from the washing machine L, the drainage from the washing machine L flows from the washing machine drain hose through the washing machine connection pipe 16 into the sealed water bottle 12 and accumulates. When it is sufficiently collected, it overflows from the opening provided on the side surface of the sealing tub 12. The waste water that has flowed out of the sealing tub 12 is discharged from the inside of the trap body 9 to the sewage side through the discharge port 9a. At this time, since the ends of the horizontal tube portion of the connecting pipe 16 for the washing machine are configured so that both ends protrude slightly outward from the outer surface of the tube portion 13a of the deodorizing tube 13, the washing machine The bubble-mixed waste water from L is first discharged only to the outside of the cylindrical portion 13 a of the deodorizing cylinder 13 and is not discharged to the inside of the deodorizing cylinder 13. Since the bubbles in the drainage are lifted with respect to the drainage by the buoyancy, the bubbles in the drainage discharged to the outside of the cylindrical portion 13a of the deodorizing cylinder 13 are directly between the outer surface of the deodorizing cylinder 13 and the inner surface of the sealing tub 12. And is discharged downstream from the opening on the side surface of the sealing tub 12 and does not flow backward from the inner surface of the deodorizing cylinder 13 to the drain port 10b.
Further, when drainage occurs on the bottom surface 2 of the washing machine waterproof pan 1 due to damage to the washing machine L itself or the washing machine drain hose, the drainage passes over the bottom surface 2 of the washing machine waterproof pan 1. Then, it passes through the eye plate member 11 of the drain port 10b, passes in the order of the inside of the deodorizing cylinder 13, the inside of the sealed water bottle 12, the opening above the sealed water bottle 12, the inside of the trap body 9 and the discharge port 9a. Discharged to the sewage side.
In addition, since the wall member 8 is watertightly attached to the recess 5 of the peripheral wall 3, even if drainage occurs inside the waterproof pan 1 for a washing machine, as long as the drainage does not accumulate at the upper end of the peripheral wall 3, Does not overflow from the inside of the waterproof pan 1 for a washing machine.
Further, in the drain trap T configured as described above, when drainage is performed in the drain trap T via the washing machine connection pipe 16 or the drain port 10b, the bottom end of the side opening is placed inside the sealing tub 12. Drainage collects up to the height. Thus, a portion filled with drainage is formed in the flow path from the drain outlet 10b or the connecting pipe 16 for the washing machine to the lower end of the opening 2a on the side surface of the sealing tub 12. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

上記のように構成した第二実施例の洗濯機用防水パンと排水トラップにおいて、長期間の使用により、排水トラップT内部に汚れが付着して異臭を生じたり、堆積した毛髪や糸くず等の塵芥、汚れ成分などで管詰まりが生じ、排水トラップTの内部を清掃する必要が生じた場合、以下の方法にて排水トラップTの部材を取り出し、清掃することができる。
まず凹部5から壁部材8を取り外し、周壁3内部に作業者の手を挿入できる隙間空間を確保する。
次に、切り欠きを拡径して、洗濯機用接続管16又は洗濯機用排水ホースから目皿部材11を取り外し、段部6、凹部5を介して周壁3の外部に取り出す。
次に、洗濯機用接続管16と洗濯機用排水ホースとの接続を解除した上で、防臭筒13とフランジ部材10との接続を解除する。
その後、接続管付き封水ユニット15を周壁3の外部に取り出す。
この排水トラップTの部材の取り出し作業に際して、清掃作業の作業者は、接続管付き封水ユニット15を取り出す際、以下に記載した理由4.乃至理由6.の理由により、底部の開口部2a(本実施例の場合にはフランジ部材10内部の排水口10b)より接続管付き封水ユニット15を上方に取り出し、図16に示したように、そのまま傾斜させることなく水平に移動させて、凹部5より取り出し作業を行う事となる。よって、底面2上に封水椀12内の封水(排水)がこぼれることがほぼ確実に無くなる。
理由4.本実施例においては、封水椀12の縦幅は封水椀12の横幅よりも短く、また防臭筒13の縦幅は封水椀12の横幅よりも短く、また封水ユニット14においても排水ユニットの縦幅は排水ユニットの横幅より短く構成してなる(接続管付き封水ユニット15の状態においては、縦幅と横幅はほぼ同一で、若干縦幅の方が短い)。
このため、従来例のように、封水椀12や防臭筒13(特に封水椀12)を傾斜させることにメリットは無く、傾斜させずに水平に移動させて周壁3から取り出す方が好適になるように構成してなる。
理由5.封水椀12、防臭筒13、及び凹部5の各下端部分、特に接続管付き封水ユニット15において下端となる封水椀12の下端部分を、側面視略水平状となるように構成してなる。これにより、接続管付き封水ユニット15を凹部5から取り出す際、接続管付き封水ユニット15を傾斜することなく取り出すガイドとして機能し、接続管付き封水ユニット15を構成する防臭筒13、封水椀12等の部材が横方向に傾斜するのを防ぐ効果を奏する。
理由6.接続管付き封水ユニット15において、洗濯機用接続管16の中央の垂直な管体を摘むようにし、そのまま上方に引き上げると、洗濯機用接続管16の水平な管体部分の両端に防臭筒13が載架した状態となり、且つツメ部13b材により防臭筒13と封水椀12が係合した状態であることから、接続管付き封水ユニット15の各部材を水平状体を維持したまま容易に引き上げることができる。この時、防臭筒13、封水椀12、及び洗濯機用接続管16の接続はいずれも固定的なものではなく、単に載架・遊びを有しての係合程度のものでしかないため、洗濯機用接続管16の中央の垂直な管体を摘んで傾斜させようとしても封水椀12の封水が錘のように作用して作業者の思うように傾斜させることができない。
結果、清掃作業者は、封水ユニット14を移動させる際は、封水ユニット14を傾斜させることなく、洗濯機用接続管16の中央の垂直な管体を摘んで、水平状態を維持したまま、移動させる事となる。
In the waterproof pan and drainage trap for the washing machine of the second embodiment configured as described above, due to long-term use, dirt adheres to the inside of the drainage trap T, and a strange odor is produced, such as accumulated hair and lint. When pipe clogging occurs due to dust, dirt components, etc., and it becomes necessary to clean the inside of the drain trap T, the member of the drain trap T can be taken out and cleaned by the following method.
First, the wall member 8 is removed from the recess 5 to secure a clearance space in which the operator's hand can be inserted into the peripheral wall 3.
Next, the diameter of the notch is expanded, the eye plate member 11 is removed from the washing machine connecting pipe 16 or the washing machine drain hose, and taken out to the outside of the peripheral wall 3 through the step 6 and the recess 5.
Next, the connection between the washing machine connection pipe 16 and the washing machine drain hose is released, and then the connection between the deodorizing cylinder 13 and the flange member 10 is released.
Thereafter, the sealing unit with connection pipe 15 is taken out of the peripheral wall 3.
When the member of the drain trap T is taken out, the cleaning operator takes the reason described below when taking out the sealing unit 15 with a connecting pipe. To reason 6 For this reason, the sealing unit with connection pipe 15 is taken out from the opening 2a at the bottom (in the case of the present embodiment, the drain port 10b inside the flange member 10), and is tilted as it is as shown in FIG. It is moved horizontally without taking out from the recess 5. Therefore, the sealed water (drainage) in the sealed water tub 12 is almost certainly not spilled on the bottom surface 2.
Reason 4 In the present embodiment, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, the vertical width of the deodorizing cylinder 13 is shorter than the horizontal width of the sealed water jar 12, and the sealed water unit 14 is also drained. The vertical width of the unit is configured to be shorter than the horizontal width of the drainage unit (in the state of the sealing unit 15 with connecting pipe, the vertical width and the horizontal width are substantially the same, and the vertical width is slightly shorter).
For this reason, there is no merit in inclining the sealed water bottle 12 or the deodorizing cylinder 13 (especially the sealed water bottle 12) as in the conventional example, and it is preferable to move it horizontally without taking it out and to take it out from the peripheral wall 3. It is comprised so that.
Reason 5. The bottom end of each of the water seal 12, the deodorizing cylinder 13, and the recess 5, particularly the bottom end of the water seal 12 that is the lower end of the water seal unit 15 with a connecting pipe is configured to be substantially horizontal when viewed from the side. Become. Thus, when the sealing unit with connection pipe 15 is taken out from the recess 5, it functions as a guide for taking out the sealing unit with connection pipe 15 without tilting, and the deodorizing cylinder 13 constituting the sealing unit with connection pipe 15, sealing There exists an effect which prevents that members, such as the water tank 12, incline to a horizontal direction.
Reason 6 In the sealing unit 15 with connecting pipe, when the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and pulled up as it is, the deodorizing cylinders are attached to both ends of the horizontal pipe portion of the connecting pipe 16 for the washing machine. Since the deodorizing cylinder 13 and the sealing tub 12 are engaged by the claw portion 13b, the members of the sealing unit with a connecting pipe 15 are maintained in a horizontal state. Can be pulled up easily. At this time, the connection of the deodorizing cylinder 13, the water seal 12 and the connecting pipe 16 for the washing machine is not fixed and is merely an engagement degree with mounting and play. Even if the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and tilted, the sealing water of the sealing tub 12 acts like a weight and cannot be tilted as desired by the operator.
As a result, when the cleaning operator moves the sealing unit 14, the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and maintained in a horizontal state without tilting the sealing unit 14. Will be moved.

このようにして排水トラップTから部材を取り出し、清掃を行った後、また場合によってはトラップ本体9内部の清掃や、排出口9aから下流側の配管の清掃作業/管詰まりの解消を、機材などを凹部5また排水口10bを介して作業を行い、清掃作業/管詰まりの解消を行った後、段落0028に記載の、洗濯機Lを洗濯機用防水パン1に載置する以外の作業を繰り返すことで、排水トラップTの部材の取り付け作業を完了させ、排水トラップTの清掃作業が完了する。 After removing the member from the drain trap T and cleaning it in this way, in some cases, cleaning the inside of the trap body 9 or cleaning the pipe downstream from the discharge port 9a / resolving clogging of the equipment, etc. After performing the work through the recess 5 and the drain port 10b to perform cleaning work / clogging of the pipe, work other than placing the washing machine L on the waterproof pan 1 for the washing machine described in paragraph 0028 is performed. By repeating, the attachment operation | work of the member of the drain trap T is completed, and the cleaning operation | work of the drain trap T is completed.

本発明の実施例は以上のようであるが、本発明は上記実施例に限定される物ではなく、主旨を変更しない範囲において自由に変更が可能である。
例えば上記第二実施例においては、段部6を有さない洗濯機用防水パン1に、封水椀12と防臭筒13とが係合することで封水ユニット14となる排水トラップTを採用してなるが、本発明は上記実施例に限定されるものではなく、段部6を有さない洗濯機用防水パン1に、封水椀12と防臭筒13とが係合しない排水トラップTを採用しても良い。この場合でも理由1.、理由2.(又は理由4.及び理由5.)により、この排水トラップTの部材の取り出し作業に際して、清掃作業の作業者は、接続管付き封水ユニット15を取り出す際、底部の開口部2aより防臭筒13、封水椀12等の排水トラップTの部材を上方に取り出し、そのまま傾斜させることなく水平に移動させて、凹部5より取り出し作業を行う事となる。よって、底面2上に封水椀12内の封水(排水)がこぼれることがほぼ確実に無くなる。
The embodiments of the present invention are as described above. However, the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention.
For example, in the second embodiment, the drainage trap T that becomes the sealing unit 14 by engaging the sealing jar 12 and the deodorizing cylinder 13 with the waterproof pan 1 for a washing machine that does not have the stepped portion 6 is adopted. However, the present invention is not limited to the above embodiment, and the drain trap T in which the sealing tub 12 and the deodorizing cylinder 13 are not engaged with the waterproof pan 1 for a washing machine not having the stepped portion 6. May be adopted. Even in this case, Reason 1. Reason 2 (Or Reason 4. and Reason 5.), when the member of the drain trap T is taken out, the worker of the cleaning work takes out the deodorizing cylinder 13 from the opening 2a at the bottom when taking out the sealing unit 15 with the connecting pipe. Then, the member of the drain trap T such as the sealing tub 12 is taken out upward, moved as it is without being inclined, and taken out from the recess 5. Therefore, the sealed water (drainage) in the sealed water tub 12 is almost certainly not spilled on the bottom surface 2.

The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body in the underfloor space is provided on the floor surface. Next, the outlet of the trap body is connected to the sewage side pipe through this opening. Further, the male screw portion of the flange portion is inserted into the opening of the waterproof pan for a washing machine, and then screwed into the female screw of the trap body. Thus, the trap body and the flange member are attached to the washing machine waterproof pan so that the flange lower surface of the flange member and the upper surface of the convex portion of the trap body sandwich the periphery of the opening of the waterproof pan for washing machine. Fixed.
Furthermore, a waterproof pan for a washing machine is fixed on the floor using screws or the like.
In addition, the water bottle is arranged so as to hang inside the flange member, and the deodorizing cylinder in which the washing machine connection pipe is housed is arranged so that the lower end is housed in the water bottle. The upper end is watertightly connected to the inner surface of the flange member. In this state, the opening inside the flange member functions as a drain outlet. Furthermore, after setting the eye plate member at the drain outlet and connecting the washing machine drain hose to the washing machine connection pipe, place the leg of the washing machine on the footrest, and the washing machine waterproof pan and drain The trap and the washing machine are completed.

上記のように構成された洗濯機用防水パンと排水トラップは、以下のようにして使用される。
洗濯機を使用し、洗濯機より排水が生じると、洗濯機からの排水は、洗濯機用排水ホースから、洗濯機用接続管を介し、封水椀内部に流入して溜まり、充分に溜まると封水椀の側面に設けられた開口から溢れ出す。封水椀から流出した排水は、トラップ本体内部から排出口を介して下水側に排出される。
また、洗濯機自体や洗濯機用排水ホースの破損等により、洗濯機用防水パンの底面上に排水が生じると、排水は、排水口の目皿部材を通過し、防臭筒内部、封水椀内部、封水椀の上方の開口、トラップ本体内部、排出口、の順番に通過し、最終的に下水側に排出される。
また、上記のように構成した排水トラップにおいて、排水トラップに排水が行われると、封水椀内部に、側面の開口の下端の高さまで排水が溜まる。これにより、排水口又は洗濯機用接続管から封水椀の側面の開口部下端までの流路に、排水で満たされた部分が形成される。この溜まった排水を封水と呼び、下水側から臭気や害虫類が屋内側に侵入しようとしても、この封水によってそれ以上屋内側に侵入されることを防止ることができる。このように、下水側から臭気や害虫類が屋内側に侵入することを防止する機能をトラップ機能と呼ぶ。
The washing machine waterproof pan and drain trap configured as described above are used as follows.
When wastewater is generated from the washing machine using the washing machine, the wastewater from the washing machine flows into the inside of the sealed water bottle from the washing machine drain hose through the washing machine connection pipe, and accumulates sufficiently. It overflows from the opening provided on the side surface of the water seal. The waste water that has flowed out from the sealed water tank is discharged from the inside of the trap body to the sewage side through the discharge port.
In addition, if drainage occurs on the bottom surface of the waterproof pan for the washing machine due to damage to the washing machine itself or the drainage hose for the washing machine, the drainage passes through the eye plate member of the drainage port, inside the deodorizing cylinder, It passes in the order of the inside, the opening above the water bottle, the inside of the trap body, and the discharge port, and is finally discharged to the sewage side.
Further, in the drain trap configured as described above, when drainage is performed on the drain trap, the drainage collects up to the height of the lower end of the opening on the side surface inside the sealed water trough. Thereby, the part filled with the waste_water | drain is formed in the flow path from a drain outlet or a connecting pipe for washing machines to the lower end of the opening part of the side surface of a water bottle. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

ところで、洗濯機からの排水は、当然に洗濯を行った後の排水であり、油分等の汚れ、毛髪、毛糸屑、砂等様々な汚れ成分と、これを衣類等の洗濯物から分離し除くために使用された洗剤成分が混入している。このため、このような排水が通過する排水トラップの部材にこれらの汚れが付着し、排水トラップの各部材が汚れたり、雑菌が繁殖して異臭を生じたり、汚れ物質が堆積するなどして内部の排水流路が詰まったりする、という問題を生じる。このような問題を解決するため、排水トラップの部材の内、封水椀、防臭筒、洗濯機用接続管、目皿部材等は、トラップ本体から着脱して清掃することが可能に構成されている。しかしながら、実際には、洗濯機用防水パンの上方に洗濯機が配置され、排水トラップの上方が洗濯機に覆われることで、洗濯機用防水パンと洗濯機との間が狭くなり、トラップの部材の取り外し作業を行うために手を差し込む事が困難であったり、洗濯機の周壁の外側に取り出すことができない、といった問題があった。
そこで、特許文献1に記載の洗濯機用防水パンと排水トラップにおいては、足置き台の間部分の周壁を側面視円弧形状とし、足置き台上に載置された洗濯機の下端と、洗濯機用防水パンの周壁上面や底面との間に作業を可能とする隙間を確保すると共に、防臭筒等、比較的に大型の排水トラップの部材を横に倒すことで、洗濯機の周壁の外側に取り出すことができるように構成している。
特許文献1に明記はされてはいないが、排水トラップのトラップ本体及びフランジ部材を洗濯機用防水パンに接続するためにはネジによる接続が一般的に利用される。このため、トラップ本体及びフランジ部材の上方の開口も、ネジの形状に合わせて平面視円形に形成される場合が殆どで、この円形の開口に合わせて配置される封水椀、防臭筒等も平面視円形を成す場合が多い。この特許文献1に記載の洗濯機用防水パンと排水トラップの場合、足置き台の間部分の周壁を側面視円弧形状とすることで、平面視円形を成す封水椀、防臭筒を、横に倒して取り出す作業が容易になるように構成してなる。
By the way, the drainage from the washing machine is a drainage after washing, and various dirt components such as oil stains, hair, yarn waste, sand and the like are separated from the laundry such as clothes and removed. The detergent components used for the purpose are mixed. For this reason, these dirt adheres to the drain trap member through which such drainage passes, and each member of the drain trap becomes dirty, miscellaneous germs grow to produce a strange odor, and dirt substances accumulate, etc. This causes a problem that the drainage flow path of the water is clogged. In order to solve such a problem, the drain trap, the sealing bottle, the deodorizing cylinder, the connecting pipe for the washing machine, the eye plate member, and the like are configured to be removable from the trap body and cleaned. Yes. However, in reality, the washing machine is disposed above the waterproof pan for the washing machine, and the upper portion of the drain trap is covered with the washing machine, so that the gap between the waterproof pan for the washing machine and the washing machine becomes narrow, and the trap There was a problem that it was difficult to insert a hand to perform the removal work of the member, or it was not possible to take it out of the peripheral wall of the washing machine.
Therefore, in the waterproof pan for a washing machine and the drain trap described in Patent Document 1, the peripheral wall between the footrests has an arc shape when viewed from the side, the lower end of the washing machine placed on the footrests, The outside of the peripheral wall of the washing machine is secured by allowing a relatively large drainage trap member such as a deodorizing cylinder to lie down while ensuring a gap between the top and bottom surfaces of the peripheral wall of the machine waterproof pan.

上記のような特許文献1に記載の洗濯機用防水パンと排水トラップの場合、以下に記載するような問題点があった。
特許文献1に記載の洗濯機用防水パン含め、通常の洗濯機用防水パンにおいて、周壁の内面や底面上等、洗濯機用防水パンの内部に排水が生じることは、実際にはほとんど無い。
何故なら、洗濯機を支障無く利用する状況では、洗濯機の排水は直接排水トラップの内部に流れ込み、洗濯機用防水パンの内部、特に底面上を排水が流れることはない為である。
洗濯機用防水パンの内部に排水が流れる場合は、洗濯機や洗濯機用ホースが故障・破損し洗濯機用防水パンの内部に排水が漏出するという極めて希な場合か、または段落0005に記載したように、清掃時に封水椀を取り出す際に、封水椀を横倒しにして内部の排水が流出した場合のいずれかの場合に限られる。
洗濯機用防水パンは排水の処理を前提とした部材であり、樹脂材料で成型され、通常の床面に排水が溢れた場合とは異なり、排水が内部に流れ出しても、修復不可能な汚れの染みを生じたり、または破損を生じたり、といった問題を生じることなく排水を下水側に排出する事は可能である。しかしながら、洗濯機用防水パン内部に排水が流れ落ち、そのまま放置すれば、排水の通過跡に一部の排水が留まり、乾燥して汚れ成分がこびり付くようにして残る。汚れの性質は排水の内容によって変化するが、髪の毛や垢などの成分、油分、洗剤成分等を含んでいる場合が多く、このような汚れ部分に雑菌が繁殖し、非衛生的で有ると共に、異臭を生じたりする、という問題が生じる。前述のように排水が洗濯機用防水パンの内部を流れることは希で、排水が繰り返し流れ込むこともほとんど無いため、後から流れ込む排水が、前の排水の汚れを洗い流す、という事もない。従って、洗濯機用防水パン内部に排水が生じた場合は、洗濯機用防水パン内部の清掃を行う必要がある。
この内、洗濯機や洗濯機用ホースが故障・破損し洗濯機用防水パンの内部に排水が漏出した場合は、修理のため洗濯機自体を移動させる必要性が生じるから、洗濯機を移動させ上方に障害物が無くなった洗濯機用防水パンの内部を清掃することに支障は生じない。
一方、特許文献1に記載の洗濯機用防水パンと排水トラップにおいて、清掃のため封水椀等の排水トラップの部材を取り出す場合、洗濯機を洗濯機用防水パン上に載置した状態で行うこととなる(元々、特許文献1の発明は、洗濯機用防水パンの上方に洗濯機を配置した状態のまま、排水トラップの部材を取り出し、清掃するための発明である)。
通常洗濯機用防水パンの内部は、排水トラップを取り付ける開口部に向かって下るように勾配を設定されるが、この勾配は極めて緩やかなため、排水の流れ方はこの勾配よりも封水椀の倒し方に強く影響を受ける。封水椀の倒し方はその時の状況に応じてまちまちだから、洗濯機用防止パン内部の排水がどの様に流れたかもまちまちであり、排水の広がり方は安定しない。洗濯機用防水パンの内部は床面すれすれの極めて低い位置に配置され、更に洗濯機に覆われて内部を視認し難いため、排水が流れた汚れ部分を確認し、汚れ部分のみを選択的に清掃するのは困難である。従って確実な清掃を行うためには、排水で汚れている部分、汚れていない部分に関係なく、洗濯機用防水パンの内部全てを清掃する、等の方法を取らざるを得ない。しかし、洗濯機の下端と洗濯機用防水パンの内部との空間は狭く、この狭隘な空間にて、洗濯機下端と洗濯機用防水パンの周壁上端との間の狭い隙間から手を差し込んで、洗濯機用防水パンの内部全てを清掃することは、極めて困難な作業である。
またホースなどを利用し水道水などを洗濯機用防水パンの内部に流して、排水の汚れを洗い流す方法も考えられるが、これもホースの向きなどによって周壁の上を超えて水道水が溢れ、洗濯機用防水パンの周壁の外側の床面に染みや破損などのダメージを与えたり、洗濯機の下面に水道水が掛かって洗濯機の故障の原因となることが考えられるため、好適な方法とは言えない。
本発明は上記問題点に鑑み発明されたものであって、清掃の際に、洗濯機用防水パンの底面上を汚すことなく、排水トラップの部材の清掃を容易に行うことができる、洗濯機用防水パンと排水トラップを提供するものである。
In the case of the waterproof pan for a washing machine and the drain trap described in Patent Document 1 as described above, there are problems as described below.
In ordinary washing machine waterproof pans including the washing machine waterproof pan described in Patent Document 1, there is virtually no drainage inside the washing machine waterproof pan, such as on the inner surface or bottom surface of the peripheral wall.
This is because in a situation where the washing machine is used without any trouble, the wastewater from the washing machine flows directly into the drain trap, and the drainage does not flow inside the waterproof pan for the washing machine, particularly on the bottom surface.
If drainage flows inside the waterproof pan for washing machines, it is extremely rare that the washing machine or washing machine hose breaks down or breaks down and the drainage leaks into the waterproof pan for washing machines, or as described in paragraph 0005 As described above, when taking out the sealing water bottle at the time of cleaning, it is limited to any case where the sealing water tank is laid down and the internal drainage flows out.
The waterproof pan for washing machines is a component premised on the treatment of wastewater, and it is molded with a resin material. Unlike the case where the wastewater overflows on the normal floor surface, even if the wastewater flows into the interior, it cannot be repaired. It is possible to discharge the waste water to the sewage side without causing a problem such as a stain or damage. However, if the wastewater flows down inside the waterproof pan for a washing machine and is left as it is, a part of the wastewater stays on the passage of the wastewater, and remains so that the dirt component sticks to dryness. The nature of the dirt changes depending on the contents of the drainage, but it often contains ingredients such as hair and dirt, oil, detergent ingredients, etc., and germs grow on these dirt parts and are unsanitary, There is a problem that a strange odor is generated. As described above, the wastewater rarely flows inside the waterproof pan for a washing machine, and the wastewater hardly flows repeatedly. Therefore, the wastewater that flows later does not wash away the dirt of the previous wastewater. Accordingly, when drainage occurs inside the waterproof pan for the washing machine, it is necessary to clean the inside of the waterproof pan for the washing machine.
Of these, if the washing machine or washing machine hose breaks down or breaks down and drainage leaks into the waterproof pan for washing machine, it will be necessary to move the washing machine for repair. There is no problem in cleaning the inside of the waterproof pan for a washing machine with no obstacles above.
On the other hand, in the waterproof pan and drain trap for a washing machine described in Patent Document 1, when a drain trap member such as a sealing tub is taken out for cleaning, the washing machine is placed on the waterproof pan for the washing machine. (Originally, the invention of Patent Document 1 is an invention for taking out and cleaning the drain trap member while the washing machine is disposed above the waterproof pan for washing machine).
Normally, the inside of a waterproof pan for a washing machine is graded so that it goes down toward the opening where the drain trap is installed, but since this slope is extremely gentle, the direction of drainage flows more than the slope. Strongly influenced by how to kill. Since the method of depressing the sealing jar varies depending on the situation at that time, it depends on how the drainage inside the washing pan for the washing machine flows, and the spreading of the drainage is not stable. The inside of the waterproof pan for the washing machine is placed at a position where the floor surface is extremely low, and it is also difficult to see the inside because it is covered with the washing machine, so check the dirty part where drainage has flowed, and select only the dirty part It is difficult to clean. Therefore, in order to perform reliable cleaning, it is necessary to take a method such as cleaning the entire interior of the waterproof pan for a washing machine, regardless of whether it is dirty or not. However, the space between the lower end of the washing machine and the inside of the waterproof pan for the washing machine is narrow, and in this narrow space, insert your hand through the narrow gap between the lower end of the washing machine and the upper peripheral wall of the waterproof pan for the washing machine. Cleaning the entire inside of the waterproof pan for a washing machine is an extremely difficult task.
You can also use a hose to drain tap water, etc., inside the waterproof pan for the washing machine to wash away dirt from the drainage, but this also causes the tap water to overflow over the peripheral wall depending on the direction of the hose, etc. A suitable method because it may cause damage such as stains or damage to the floor surface outside the peripheral wall of the waterproof pan for washing machines, or it may cause tap water on the lower surface of the washing machine and cause malfunction of the washing machine. It can not be said.
The present invention has been invented in view of the above-described problems, and is capable of easily cleaning a drain trap member without soiling the bottom surface of a waterproof pan for a washing machine during cleaning. A waterproof pan and drain trap are provided.

However, the vertical positional relationship between the lower end of the back surface of the step pressing portion 2b provided on the periphery of the opening 2a and the lower end of the outer peripheral wall 3 on the bottom surface 2 of the step portion 6 is as follows. The lower end of the back surface is configured to be higher than the lower end of the outer peripheral wall 3. Further, at this time, the height width of both is configured to provide at least a width equal to or greater than the thickness of the convex portion 9b of the trap body 9 in the vertical direction.
Moreover, the height width from the bottom face 2 of the recessed part 5 and the bottom face 2 of the step part 6 to the upper end of the footrest 4 is wider than the vertical width of the sealing tub 12 and the deodorizing cylinder 13 of the drain trap T described later. In addition, the height width H2 from the bottom surface 2 other than the step portion 6 to the upper end of the footrest 4 is configured so as to be narrower than the vertical width of the sealing jar 12 and the deodorizing cylinder 13.
Further, the bottom surface 2 other than the step portion 6 and the bottom surface 2 of the step portion 6 are connected to each other by a side wall of the step portion 6 that is substantially suspended, and the side wall of the step portion 6 is connected to the wall surface of the side surface of the recess 5. While forming the return portion 7 which is a wall surface slightly inward from the side surface, the connection is made continuously.
The wall member 8 is a substantially plate-like member that is attached to the recess 5 of the waterproof pan 1 for a washing machine in a watertight and detachable manner. The outer side surface and the upper end of the peripheral wall 3 around the recess 5 are the peripheral wall 3. It is attached so as to be continuous.
Except for the wall member 8 (and a fixing screw member and a packing for watertight connection), the waterproof pan 1 for a washing machine is molded as an integral member with a resin material such as FRP.
The drainage trap T includes the trap body 9, the flange member 10, the water seal 12, the deodorizing cylinder 13, the washing machine connection pipe 16, and the eye plate member 11 described below.
The trap body 9 has a substantially cylindrical shape with a bottom, is provided with an opening at the top, and a discharge port 9a for connecting a drain pipe on the sewage side to the side surface. The upper end portion inner peripheral surface is provided with a female screw and a convex portion 9b protruding from the upper end portion in the outer peripheral direction along the peripheral edge.
The flange member 10 has a substantially cylindrical shape, and has an outer surface provided with a male screw threadedly engaged with a female screw of the trap body 9 and a flange portion 10a protruding along the peripheral edge in the outer peripheral direction at the upper end portion. . The flange member 10 configured as described above forms a drain port 10b when the construction is completed.
The water seal 12 has a bottomed cylindrical shape and is provided with openings on the upper upper surface and the upper side surface. Moreover, this sealing water tank 12 is comprised so that an upper part may be suspended inside the flange member 10 at the time of construction.
The deodorizing cylinder 13 is a substantially cylindrical member, and the upper portion is configured to have a mortar shape that increases in diameter as it goes upward. Further, when the construction is completed, the upper end portion is connected to the drain port 10b in a watertight manner, and the lower end portion is disposed inside the sealing tub 12 and below the lower end of the opening on the side surface of the sealing tub 12. .
The connecting pipe 16 for the washing machine is a tubular body branched into a substantially T-shape, and the vertical tubular body portion is placed inside the tubular body portion 13a of the deodorizing cylinder 13 with the T-shape turned upside down during construction. The horizontal tube portion is disposed between the lower end of the deodorizing cylinder 13 and the upper surface of the lower wall of the sealing tub 12 (the horizontal tube portion is shaped flat). Moreover, the end part of a horizontal pipe part is comprised so that it may protrude a little outside rather than the outer surface of the cylinder part 13a of the deodorizing cylinder 13 in both ends. At the time of construction, the upper end of the central vertical pipe body of the connecting pipe 16 for the washing machine configured as described above is connected to a drain hose for the washing machine that discharges drainage from the washing machine, and drains from the washing machine. Is discharged to the outside of the deodorizing cylinder 13 and inside the sealed water bottle 12.
The eye plate member 11 is a member disposed in the drainage port 10b, and has an opening through which the washing machine connection pipe 16 is passed in the central portion and a plurality of holes in the peripheral portion so that the waterproof pan 1 for the washing machine is provided. When drainage occurs on the top, it is configured to separate and collect hair and large garbage in the drainage. The eye plate member 11 is formed with a notch that opens from the peripheral edge to the central opening. By utilizing the elasticity of the eye plate member 11 and expanding the notch, the connecting pipe 16 for the washing machine and the washing machine are formed. The eye plate member 11 can be taken out without releasing the connection with the water drain hose.
Of the above members, the lower end portions of the water seal 12, the deodorizing cylinder 13, and the connecting pipe 16 for the washing machine are configured to be substantially horizontal when viewed from the side. As described above, the term “horizontal” as used herein is an expression indicating that it is formed in a shape that is parallel to the side view horizontal plane in a state where construction and attachment of each member are completed. It does not indicate a “flat surface”. Strictly speaking, the lower end portion of the deodorizing cylinder 13 has a cylindrical shape and is not a “surface”, but this is a virtual flat surface formed by continuing the cylindrical lower end portion. This indicates that the surface is parallel to the side view horizontal plane in the state where the attachment of the member is completed.
Further, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, and the vertical width of the deodorizing cylinder 13 is configured to be shorter than the horizontal width of the sealed water jar 12.
The washing machine L disposed on the waterproof pan 1 for a washing machine is a drainage device (a device that generates drainage by use) that has a substantially box shape, and has a loading port for laundry on the side surface, With four legs and a washing machine drain hose (only the elbow pipe E is shown) for discharging waste water containing detergent and dirt components generated by using the washing machine L It becomes.

上記のように構成された洗濯機用防水パンと排水トラップは、以下のように施工される。尚、特に記載しないが、以下の施工の際、水密的な接続が要求される部分には、必要に応じて接着やパッキングを利用したネジ接続などにより、水密的に接続される。
まず床面Fにトラップ本体9を配置するための開口を設ける。次に、この開口を通してトラップ本体9の排出口9aを下水側配管に接続する。更に、フランジ部材10の筒体部分13aを開口部2aに挿通し、段押し部2bの上面にフランジ部材10のフランジ部10aを収納した上で、フランジ部材10の雄ネジを、トラップ本体9の雌ネジに螺合させる。これにより、フランジ部材10のフランジ部10a下面と、トラップ本体9の凸部9b上面とで、洗濯機用防水パン1の開口部2aの周縁、即ち段押し部2bの底面2を挟持するようにして、トラップ本体9とフランジ部材10が、洗濯機用防水パン1に固定される。
更に床面F上に洗濯機用防水パン1を、ビスなどを使用して固定する。
この時、本実施例では、前述のように、段押し部2bの裏面の下端と、外側の周壁3の下端との上下方向の位置関係については、段押し部2bの裏面の下端の方が、少なくともトラップ本体9の凸部9bの上下方向の厚み分以上の幅を有して上方となるように構成されてなるため、床面Fに排水トラップTを配置するために設ける開口は、トラップ本体9の凸部9bを除く側面形状にのみ合わせて開口するだけで良い物となる。
簡単に説明すると、床面Fの開口と凸部9bの周縁との間に隙間が広く設けられていたり、凸部9bの下方に床面Fが存在しない状態であると、床下空間の通気などが凸部9bの隙間から洩れ、屋内側に不要な通気を生じて居住者に不快感を与えてしまう、等の問題を生じる。これを防止するために、従来例の場合、床面Fの開口は、トラップ本体9の側面の開口に、更に凸部9bの周縁の開口に合わせて段を設ける二段形状にしなければならなかった。しかし、本第一実施例では、凸部9bが床面Fに食い込むことが無くなったため、床面Fを、トラップ本体9の側面形状にのみ合わせて開口するだけで良くなり、作業が簡易となった分、作業性を良い物とすることができる(側面に設けた排出口に対応するため、部分的に大きく切り拡げ、トラップ本体を取り付けた後に板材で余計な開口部分を塞ぐ場合があるが、図1では省略する)。
The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body 9 is provided on the floor surface F. Next, the discharge port 9a of the trap body 9 is connected to the sewage side pipe through this opening. Further, the tubular portion 13a of the flange member 10 is inserted into the opening 2a, and the flange portion 10a of the flange member 10 is accommodated on the upper surface of the stepped portion 2b. Screw onto the female screw. Accordingly, the lower surface of the opening 2a of the waterproof pan 1 for a washing machine, that is, the bottom surface 2 of the stepped portion 2b is sandwiched between the lower surface of the flange portion 10a of the flange member 10 and the upper surface of the convex portion 9b of the trap body 9. Thus, the trap body 9 and the flange member 10 are fixed to the waterproof pan 1 for a washing machine.
Further, the waterproof pan 1 for a washing machine is fixed on the floor surface F using screws or the like.
At this time, in this embodiment, as described above, regarding the vertical positional relationship between the lower end of the back surface of the step pressing portion 2b and the lower end of the outer peripheral wall 3, the lower end of the back surface of the step pressing portion 2b is The opening provided for disposing the drainage trap T on the floor F has a width equal to or greater than the thickness of the convex portion 9b of the trap body 9 in the vertical direction. It becomes a thing which only needs to open according to the side shape except the convex part 9b of the main body 9.
Briefly, if there is a wide gap between the opening of the floor surface F and the peripheral edge of the convex portion 9b, or if the floor surface F does not exist below the convex portion 9b, ventilation in the underfloor space, etc. Leaks from the gap between the convex portions 9b, causing unnecessary ventilation on the indoor side and causing the occupant to feel uncomfortable. In order to prevent this, in the case of the conventional example, the opening of the floor surface F must be formed in a two-stage shape in which a step is provided in accordance with the opening on the side surface of the trap body 9 and the opening on the peripheral edge of the convex portion 9b. It was. However, in the first embodiment, since the convex portion 9b does not bite into the floor surface F, it is only necessary to open the floor surface F according to the side surface shape of the trap body 9, and the operation is simplified. Therefore, workability can be improved (in order to correspond to the discharge port provided on the side surface, it may be partially enlarged and expanded, and after installing the trap body, the extra opening may be blocked with a plate material. , Omitted in FIG. 1).

次に、フランジ部材10内部につり下げるようにして、封水椀12をトラップ本体9内部に配置すると共に、洗濯機用接続管16を内部に収納した防臭筒13の、上端のすり鉢状部分の外周部分を、フランジ部材10内面に対して水密的に接続する。
これにより、洗濯機用接続管16は、T字を上下逆転した状態にて、また、水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するようにして、排水トラップT内部に取り付けることができる。
この状態で、フランジ部材10の内部の開口が、排水口10bとして機能する。更に排水口10bに目皿部材11をセットし、エルボ管E等を利用し洗濯機用接続管16に洗濯機用排水ホースを接続した上で、足置き台4上に洗濯機の脚部を載置する。最後に、凹部5に壁部材8を水密的に取り付けて、洗濯機用防水パンと排水トラップ、及び洗濯機の施工が完了する。
Next, the sealing tub 12 is disposed inside the trap body 9 so as to hang inside the flange member 10 and the mortar-shaped portion of the upper end of the deodorizing cylinder 13 housing the washing machine connection pipe 16 therein. The outer peripheral portion is watertightly connected to the inner surface of the flange member 10.
As a result, the connecting pipe 16 for the washing machine is in a state in which the T-shape is turned upside down, and the ends of the horizontal tube part are slightly outside the outer surface of the cylinder part 13a of the deodorizing cylinder 13 at both ends. Can be attached to the inside of the drain trap T.
In this state, the opening inside the flange member 10 functions as the drain port 10b. Further, the eye plate member 11 is set in the drain port 10b, and the washing machine drain hose is connected to the washing machine connection pipe 16 by using the elbow pipe E or the like. Place. Finally, the wall member 8 is watertightly attached to the recess 5 to complete the construction of the waterproof pan for the washing machine, the drain trap, and the washing machine.

上記のように構成された洗濯機用防水パンと排水トラップは、以下のようにして使用される。
洗濯機Lを使用し、洗濯機Lより排水が生じると、洗濯機Lからの排水は、洗濯機用排水ホースから、洗濯機用接続管16を介し、封水椀12内部に流入して溜まり、充分に溜まると封水椀12の側面に設けられた開口から溢れ出す。封水椀12から流出した排水は、トラップ本体9内部から排出口9aを介して下水側に排出される。この際、洗濯機用接続管16の水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するように構成されてなるため、洗濯機Lからの泡混じりの排水は、まず防臭筒13の筒体部分13aの外部にのみ排出され、防臭筒13の内部には排出されない。そして排水中の泡はその浮力により排水に対して浮き上がるから、防臭筒13の筒体部分13aの外部に排出された排水中の泡はそのまま防臭筒13外側面と封水椀12内側面の間を通過し、封水椀12側面の開口から下流側に排出され、防臭筒13内面から排水口10bに逆流することは無い。
また、洗濯機L自体や洗濯機用排水ホースの破損等により、洗濯機用防水パン1の底面2上に排水が生じると、排水は、少なくとも洗濯機用防水パン1の段部6の底面2上を通過した上で、排水口10bの目皿部材11を通過し、防臭筒13内部、封水椀12内部、封水椀12の上方の開口、トラップ本体9内部、排出口9a、の順に通過し、最終的に下水側に排出される。
尚、周壁3の凹部5には、壁部材8が水密的に取り付けられているため、洗濯機用防水パン1内部に排水が生じても、周壁3の上端にまで排水が溜まらない限り、排水が洗濯機用防水パン1内部より溢れ出る事はない。
また、上記のように構成した排水トラップTにおいて、洗濯機用接続管16又は排水口10bを介し、排水トラップT内に排水が行われると、封水椀12内部に、側面の開口の下端の高さまで排水が溜まる。これにより、排水口10b又は洗濯機用接続管16から封水椀12の側面の開口部2a下端までの流路に、排水で満たされた部分が形成される。この溜まった排水を封水と呼び、下水側から臭気や害虫類が屋内側に侵入しようとしても、この封水によってそれ以上屋内側に侵入されることを防止ることができる。このように、下水側から臭気や害虫類が屋内側に侵入することを防止する機能をトラップ機能と呼ぶ。
The washing machine waterproof pan and drain trap configured as described above are used as follows.
When the washing machine L is used and drainage is generated from the washing machine L, the drainage from the washing machine L flows from the washing machine drain hose through the washing machine connection pipe 16 into the sealed water bottle 12 and accumulates. When it is sufficiently collected, it overflows from the opening provided on the side surface of the sealing tub 12. The waste water that has flowed out of the sealing tub 12 is discharged from the inside of the trap body 9 to the sewage side through the discharge port 9a. At this time, since the ends of the horizontal tube portion of the connecting pipe 16 for the washing machine are configured so that both ends protrude slightly outward from the outer surface of the tube portion 13a of the deodorizing tube 13, the washing machine The bubble-mixed waste water from L is first discharged only to the outside of the cylindrical portion 13 a of the deodorizing cylinder 13 and is not discharged to the inside of the deodorizing cylinder 13. Since the bubbles in the drainage are lifted with respect to the drainage by the buoyancy, the bubbles in the drainage discharged to the outside of the cylindrical portion 13a of the deodorizing cylinder 13 are directly between the outer surface of the deodorizing cylinder 13 and the inner surface of the sealing tub 12. And is discharged downstream from the opening on the side surface of the sealing tub 12 and does not flow backward from the inner surface of the deodorizing cylinder 13 to the drain port 10b.
Further, if drainage occurs on the bottom surface 2 of the washing machine waterproof pan 1 due to damage to the washing machine L itself or the washing machine drain hose, etc., the drainage is at least the bottom surface 2 of the step portion 6 of the washing machine waterproof pan 1. After passing through the top, it passes through the eye plate member 11 of the drainage port 10b, and in the order of the inside of the deodorizing cylinder 13, the inside of the sealing tub 12, the opening above the sealing tub 12, the inside of the trap body 9, and the discharge port 9a. Passes through and is finally discharged to the sewage side.
In addition, since the wall member 8 is watertightly attached to the recess 5 of the peripheral wall 3, even if drainage occurs inside the waterproof pan 1 for a washing machine, as long as the drainage does not accumulate at the upper end of the peripheral wall 3, Does not overflow from the inside of the waterproof pan 1 for a washing machine.
Further, in the drain trap T configured as described above, when drainage is performed in the drain trap T via the washing machine connection pipe 16 or the drain port 10b, the bottom end of the side opening is placed inside the sealing tub 12. Drainage collects up to the height. Thus, a portion filled with drainage is formed in the flow path from the drain outlet 10b or the connecting pipe 16 for the washing machine to the lower end of the opening 2a on the side surface of the sealing tub 12. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

上記のように構成した第一実施例の洗濯機用防水パンと排水トラップにおいて、長期間の使用により、排水トラップT内部に汚れが付着して異臭を生じたり、堆積した毛髪や糸くず等の塵芥、汚れ成分などで管詰まりが生じ、排水トラップTの内部を清掃する必要が生じた場合、以下の方法にて排水トラップTの部材を取り出し、清掃することができる。
まず凹部5から壁部材8を取り外し、周壁3内部に作業者の手を挿入できる隙間空間を確保する。
次に、切り欠きを拡径して、洗濯機用接続管16又は洗濯機用排水ホースから目皿部材11を取り外し、段部6、凹部5を介して周壁3の外部に取り出す。
次に、洗濯機用接続管16と洗濯機用排水ホースとの接続を解除した上で、防臭筒13とフランジ部材10との接続を解除する。
その後、防臭筒13、洗濯機用接続管16、封水椀12をそれぞれ周壁3の外部に取り出す。
この排水トラップTの部材の取り出し作業に際して、清掃作業の作業者は、防臭筒13、封水椀12等の各部材を取り出す際、以下に記載した理由1.乃至理由3.の理由により、底部の開口部2a(本実施例の場合にはフランジ部材10内部の排水口10b)より防臭筒13、封水椀12をそれぞれ上方に取り出し、そのまま傾斜させることなく水平に移動させて、図8に示したように凹部5より取り出し作業を行う事となる。よって、段部6以外の底面2上に封水椀12内の封水(排水)がこぼれることがほぼ確実に無くなる。
理由1.本実施例においては、封水椀12の縦幅は封水椀12の横幅よりも短く、また防臭筒13の縦幅は封水椀12の横幅よりも短くなるように構成してなるため、従来例のように、封水椀12や防臭筒13(特に封水椀12)を傾斜させることにメリットは無く、傾斜させずに水平に移動させて周壁3から取り出す方が好適になるように構成してなる。
理由2.上記清掃作業において、段部6はガイドとして機能し、防臭筒13、封水椀12等の部材が横方向に傾斜するのを防ぐ効果を奏する。
理由3.封水椀12、防臭筒13、及び凹部5の各下端部分を、側面視略水平状となるように構成してなる。これにより、封水椀12、防臭筒13を凹部5から取り出す際、封水椀12、防臭筒13を傾斜することなく取り出すガイドとして機能し、防臭筒13、封水椀12等の部材が横方向に傾斜するのを防ぐ効果を奏する。
In the waterproof pan and drainage trap for the washing machine of the first embodiment configured as described above, due to long-term use, dirt adheres to the inside of the drainage trap T, and a strange odor is produced, such as accumulated hair and lint. When pipe clogging occurs due to dust, dirt components, etc., and it becomes necessary to clean the inside of the drain trap T, the member of the drain trap T can be taken out and cleaned by the following method.
First, the wall member 8 is removed from the recess 5 to secure a clearance space in which the operator's hand can be inserted into the peripheral wall 3.
Next, the diameter of the notch is expanded, the eye plate member 11 is removed from the washing machine connecting pipe 16 or the washing machine drain hose, and taken out to the outside of the peripheral wall 3 through the step 6 and the recess 5.
Next, the connection between the washing machine connection pipe 16 and the washing machine drain hose is released, and then the connection between the deodorizing cylinder 13 and the flange member 10 is released.
Thereafter, the deodorizing cylinder 13, the washing machine connection pipe 16, and the water seal 12 are taken out of the peripheral wall 3.
When the member of the drain trap T is taken out, the cleaning operator takes the following reasons when taking out the members such as the deodorizing cylinder 13 and the water seal 12. To reason 3 For this reason, the deodorizing cylinder 13 and the water seal 12 are taken out from the opening 2a at the bottom (in the case of this embodiment, the drain port 10b inside the flange member 10) and moved horizontally without being inclined. Thus, as shown in FIG. Therefore, it is almost certainly eliminated that the sealed water (drainage) in the sealed water bottle 12 is spilled on the bottom surface 2 other than the step portion 6.
Reason 1. In this embodiment, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, and the vertical width of the deodorizing cylinder 13 is configured to be shorter than the horizontal width of the sealed water jar 12, As in the conventional example, there is no merit in inclining the sealed water bottle 12 or the deodorizing cylinder 13 (especially the sealed water bottle 12), and it is preferable to move it horizontally without being inclined and take it out from the peripheral wall 3. Consists of.
Reason 2 In the cleaning operation, the step portion 6 functions as a guide, and has an effect of preventing members such as the deodorizing cylinder 13 and the water seal 12 from being inclined in the lateral direction.
Reason 3. The bottom ends of the water seal 12, the deodorizing cylinder 13, and the recess 5 are configured to be substantially horizontal when viewed from the side. Thereby, when taking out the sealing water bottle 12 and the deodorizing cylinder 13 from the recessed part 5, it functions as a guide which takes out the sealing water bottle 12 and the deodorizing cylinder 13 without inclining, and members, such as the deodorizing cylinder 13 and the sealing water bottle 12, are sideways. There is an effect of preventing tilting in the direction.

更に本実施例では、段部6以外の底面2から、足置き台4上端までの高さ幅H2を封水椀12及び防臭筒13の高さ幅より狭くすることで、段部6以外の底面2上に封水椀12及び防臭筒13を移動させることが不可能に構成している。これにより、段部6以外の底面2上に封水椀12内の封水(排水)がこぼれることが確実に無くなる。また万一封水をこぼしてしまった場合でも、封水は凹部5に連通する段部6上にのみこぼれるため、清掃が必要な箇所は、視認し易く且つ作業者が手を差し込みやすい凹部5及び段部6のみに限定され、清掃が極めて容易である。 Furthermore, in this embodiment, the height width H2 from the bottom surface 2 other than the step portion 6 to the upper end of the footrest 4 is made narrower than the height width of the sealing jar 12 and the deodorizing cylinder 13, so It is impossible to move the water seal 12 and the deodorizing cylinder 13 on the bottom surface 2. Thereby, it is surely prevented that the sealed water (drainage) in the sealed water bottle 12 is spilled on the bottom surface 2 other than the step portion 6. Even if the spilled water is spilled, the sealed water is spilled only on the stepped portion 6 communicating with the recessed portion 5, so that the portion that needs to be cleaned is easily visible and the operator can easily insert the hand into the recessed portion 5. And it is limited only to the step part 6, and cleaning is very easy.

このようにして排水トラップTから部材を取り出し、清掃を行った後、また場合によってはトラップ本体9内部の清掃や、排出口9aから下流側の配管の清掃作業/管詰まりの解消を、機材などを凹部5また排水口10bを介して作業を行い、清掃作業/管詰まりの解消を行った後、段落0021に記載の、洗濯機Lを洗濯機用防水パン1に載置する以外の作業を繰り返すことで、排水トラップTの部材の取り付け作業を完了させ、排水トラップTの清掃作業が完了する。 After removing the member from the drain trap T and cleaning it in this way, in some cases, cleaning the inside of the trap body 9 or cleaning the pipe downstream from the discharge port 9a / resolving clogging of the equipment, etc. After carrying out the work through the recess 5 and the drain port 10b to perform the cleaning work / clogging of the tube, the work other than placing the washing machine L on the waterproof pan 1 for the washing machine described in paragraph 0021 is performed. By repeating, the attachment operation | work of the member of the drain trap T is completed, and the cleaning operation | work of the drain trap T is completed.

次に、本発明の第二実施例について、図面を参照しつつ説明する。
図9乃至図20に示した、本発明の第二実施例の洗濯機用防水パン及び排水トラップは、請求項3乃至請求項9に対応する実施例であって、以下に記載する、洗濯機用防水パン1及び排水トラップTより構成されてなり、以下に記載する洗濯機Lに利用される。
洗濯機用防水パン1は、平面視略正方形形状を成す、開口部2aを有する底面2と、該底面2の四隅に設けた足置き台4と、底面2の周囲から上方に向かって立設する周壁3と、から構成されてなる。尚、周壁3の一部は足置き台4と一体に構成されてなる。但し、足置き台4の上端は、隣接する周壁3の上端よりも高い位置に設けられてなり、このため足置き台4上端が周壁3上端よりも高い位置となるように構成されている、と言える。
開口部2aは底面2上に設けられた平面視円形の開口であり、その周囲には後述する排水トラップTのフランジ部材10のフランジ部10aを収納して、フランジ部10a上面が底面2上面とほぼ同じ高さ位置となるようにするための、下方に窪んだ段押し部2bを備えてなる。
周壁3は、図9乃至図11に示したように、板状の部材を断面が上方に凸となるようにして折り返した、略V字形状に構成されてなる。この内、内側の周壁3の下端は底面2に連続してなり、外側の周壁3は、底面2、特に開口部2a周辺の段押し部2bの裏面の下端に対し、後述するトラップ本体9の凸部9bの上下方向の厚み分以上の幅を有するようにして、より下方となる高さ位置まで設けられてなる。
詳述すると、開口部2a周辺に設けた段押し部2bの裏面の下端と、外側の周壁3の下端との上下方向の位置関係については、段押し部2bの裏面の下端の方が、外側の周壁3の下端よりも上方となるように構成される。またこの時の両者の高さ幅については、少なくともトラップ本体9の凸部9bの上下方向の厚み分以上の幅を設けるように構成してなる。
また、該凹部5の下端部分は、図9、図16に示したように、側面視略水平状となるように構成されてなる。尚、ここでいう「水平状」とは施工及び各部材の取り付けが完了した状態において、側面視水平面に平行となるような形状に形成されていることを指し示す表現であり、単に「平坦面」を指し示すものでは無い。
また本実施例において、後述する排水トラップTの封水椀12及び防臭筒13を組み合わせた封水ユニット14の状態に、更にその内部に洗濯機用排水接続管を収納した状態(以下「接続管付き封水ユニット15」と記載)では、洗濯機用排水接続管が防臭筒13よりも若干上方に突出するように構成されてなる。この接続管付き封水ユニット15における、洗濯機用排水接続管の上端から封水椀12の下端までの縦幅は、凹部5下端から、足置き台4上端までの高さ幅H1よりも幅狭となるように構成されてなる。
壁部材8は、洗濯機用防水パン1の凹部5に、水密的且つ着脱自在に取り付けられる略板状の部材であって、凹部5周辺の周壁3に対し、外側の側面及び上端が周壁3と連続するようにして取り付けられる。
尚、上記壁部材8(及び固定の為のビス部材や、水密的な接続を行うパッキング)を除き、洗濯機用防水パン1は、FRP等の樹脂材料によって一体の部材として成型されてなる。
排水トラップTは、以下に記載した、トラップ本体9、フランジ部材10、封水椀12、防臭筒13、洗濯機用接続管16、目皿部材11、より構成されてなる。
トラップ本体9は、有底略円筒状にして、上方に開口を備え、側面に下水側の排水管を接続する排出口9aを備えてなる。また、上端部分内周面には雌ネジを備えると共に、上端部分から外周方向に周縁に沿って突出した凸部9bを備えてなる。
フランジ部材10は、略円筒形状にして、外側面にトラップ本体9の雌ネジと螺合する雄ネジを備えると共に、上端部分に、外周方向に周縁に沿って突出したフランジ部10aを備えてなる。上記のように構成したフランジ部材10は、施工完了時内部に排水口10bを形成する。
封水椀12は、有底筒状にして、上方上面、及び側面上方に開口を備えてなる。またこの封水椀12は、上方部分が、施工時フランジ部材10内部につり下げられるように構成される。
防臭筒13は略円筒状の部材であって、上方部分は、上に行くほど拡径するすり鉢形状を成すすように構成される。また、施工完了時、上端部分は排水口10bに水密的に接続されると共に、下端部分は封水椀12内部であって、封水椀12の側面の開口の下端よりも下方に配置される。
更に本実施例においては、すり鉢形状部分の下面に、封水椀12の側面の開口と係合するツメ部13bを備えてなる。このツメ部13bは封水椀12に対し若干の遊びを有した状態で係合するものであって、施工完了時、封水椀12はフランジ部材10内部につり下げられ、防臭筒13のツメ部13bに対しては浮いた状態に配置される。但し、清掃時等防臭筒13とフランジ部材10との水密的な接続を解除された際、防臭筒13を上方に引き上げると、そのままツメ部13bにて係合された封水椀12を引き上げることができる。
洗濯機用接続管16は、略T字形状に分岐した管体であって、施工時にはT字を上下逆転した状態にて、垂直な管体部分は防臭筒13の筒体部分13aの内部に、水平な管体部分は防臭筒13下端と封水椀12の下壁上面との間に配置される(水平な管体部分は偏平につぶされたような形状を成す)。また、水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するように構成されてなる。施工時、このように構成された洗濯機用接続管16の内、中央の垂直な管体の上端は、洗濯機Lからの排水を排出する洗濯機用排水ホースに接続され、洗濯機Lからの排水を、防臭筒13の外側であって、封水椀12の内部に排出する。尚、施工完了時、洗濯機用接続管16の内、中央の垂直な管体、及び封水椀12、防臭筒13は、同心円状に配置される。
目皿部材11は排水口10bに配置される部材であって、中央部分に洗濯機用接続管16を通す開口を設けると共に、周囲部分には複数の孔を設けて、洗濯機用防水パン1上に排水が生じた場合に、排水中の毛髪や大きなゴミを分離・捕集するように構成されてなる。目皿部材11には周縁から中央の開口まで開口する切り欠きが形成されてなり、目皿部材11の弾性を利用し、該切り欠きを押し広げる事で、洗濯機用接続管16と洗濯機用排水ホースとの接続を解除することなく、目皿部材11を取り出すことができる。
尚、上記各部材の内、封水椀12、防臭筒13、及び洗濯機用接続管16の下端部分は、側面視略水平状となるように構成してなる。前述のように、ここでいう「水平状」とは施工及び各部材の取り付けが完了した状態において、側面視水平面に平行となるような形状に形成されていることを指し示す表現であり、単に「平坦面」を指し示すものでは無い。また、厳密には防臭筒13の下端部分は筒形状であって「面」ではないが、これは筒形状の下端部分を連続することで形成される、仮想的な平坦面が、施工及び各部材の取り付けが完了した状態において、側面視水平面に平行となるような面であることを指し示すものである。
また、封水椀12の縦幅は封水椀12の横幅よりも短く、また防臭筒13の縦幅は封水椀12の横幅よりも短くなるように構成してなる。
更に本実施例では、このように、防臭筒13と封水椀12をツメ部13bにて係合することで、図20に示したような、防臭筒13と封水椀12とで封水ユニット14を構成する。この封水ユニット14の状態では、防臭筒13が封水椀12の蓋をするような位置に配置されるため、封水椀12内部の封水(排水)がこぼれ出ることをより確実に防止することができる。
また、この封水ユニット14の状態においても、封水ユニット14の縦幅は、封水ユニット14の横幅よりも短くなるように構成されてなる。
更に、接続管付き封水ユニット15の状態では、洗濯機用排水接続管が防臭筒13よりも若干上方に突出するように構成されてなる。この封水ユニット14に洗濯機用排水接続管を組み合わせた状態における、洗濯機用排水接続管の上端から封水椀12の下端までの縦幅は、凹部5下端から、足置き台4上端までの高さ幅H1よりも幅狭となるように構成してなる。
また、前述のように防臭筒13と封水椀12の内部には洗濯機用接続管16が収納されてなり、洗濯機用接続管16の水平な管体部分の端部が、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するように構成されている。このため、洗濯機用接続管16の中央の垂直な管体を摘むようにし、そのまま上方に引き上げると、洗濯機用接続管16の水平な管体部分の両端に防臭筒13が載架した状態となり(水平な管体部分は偏平につぶされたような形状を成すため、上面が平坦であることも、洗濯機用接続管16の水平な管体部分の両端に防臭筒13が安定した状態で載架するために有効に作用する)、且つツメ部13b材により防臭筒13と封水椀12が係合した状態であることから、接続管付き封水ユニット15を水平状体を維持したまま容易に引き上げることができる。
また、洗濯機用防水パン1上に配置される洗濯機Lは、略箱体を成す排水機器(使用により排水を生じる機器)であって、側面に洗濯物などの投入口を有すると共に、下方に4つの脚部を有し、また洗濯機Lの使用により生じた、洗剤や汚れ成分を含んだ排水を排出するための洗濯機用排水ホース(端部となるエルボ管Eのみ図示)を備えてなる。

As described above, the term “horizontal” as used herein is an expression indicating that it is formed in a shape that is parallel to the side view horizontal plane in a state where construction and attachment of each member are completed. It does not indicate a “flat surface”. Strictly speaking, the lower end portion of the deodorizing cylinder 13 has a cylindrical shape and is not a “surface”, but this is a virtual flat surface formed by continuing the cylindrical lower end portion. This indicates that the surface is parallel to the side view horizontal plane in the state where the attachment of the member is completed.
Further, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, and the vertical width of the deodorizing cylinder 13 is configured to be shorter than the horizontal width of the sealed water jar 12.
Further, in this embodiment, the deodorizing cylinder 13 and the sealing water bottle 12 are engaged with each other at the claw portion 13b as described above, so that the water is sealed between the deodorizing cylinder 13 and the sealing water bottle 12 as shown in FIG. The unit 14 is configured. In the state of the sealing water unit 14, the deodorizing cylinder 13 is arranged at a position that covers the sealing water bottle 12, so that the sealing water (drainage) inside the sealing water bottle 12 is more reliably prevented from spilling out. can do.
Even in the state of the sealed water unit 14, the vertical width of the sealed water unit 14 is configured to be shorter than the horizontal width of the sealed water unit 14.
Furthermore, in the state of the sealing unit 15 with the connecting pipe, the drain connecting pipe for the washing machine is configured to protrude slightly above the deodorizing cylinder 13. The vertical width from the upper end of the drainage connection pipe for washing machine to the lower end of the sealing tub 12 in the state where the drainage connection pipe for washing machine is combined with the sealing water unit 14 is from the lower end of the recess 5 to the upper end of the footrest 4. The height is configured to be narrower than the width H1 .
Further, as described above, the washing machine connecting pipe 16 is housed inside the deodorizing cylinder 13 and the water seal 12, and the end of the horizontal tube portion of the washing machine connecting pipe 16 is deodorized at both ends. The cylinder 13 is configured to protrude slightly outward from the outer surface of the cylindrical portion 13a. Therefore, when the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked up and pulled up as it is, the deodorizing cylinder 13 is mounted on both ends of the horizontal pipe portion of the connecting pipe 16 for the washing machine. (Since the horizontal tube portion is flattened, the top surface is flat, and the deodorizing cylinder 13 is stable at both ends of the horizontal tube portion of the connecting pipe 16 for the washing machine. In addition, since the deodorizing cylinder 13 and the sealing water bottle 12 are engaged by the claw portion 13b, the sealing unit with a connecting pipe 15 is maintained in a horizontal state. It can be easily pulled up.
The washing machine L disposed on the waterproof pan 1 for a washing machine is a drainage device (a device that generates drainage by use) that has a substantially box shape, and has a loading port for laundry on the side surface, With four legs and a washing machine drain hose (only the elbow pipe E is shown) for discharging waste water containing detergent and dirt components generated by using the washing machine L It becomes.

上記のように構成された洗濯機用防水パンと排水トラップは、以下のように施工される。尚、特に記載しないが、以下の施工の際、水密的な接続が要求される部分には、必要に応じて接着やパッキングを利用したネジ接続などにより、水密的に接続される。
まず床面Fにトラップ本体9を配置するための開口を設ける。次に、この開口を通してトラップ本体9の排出口9aを下水側配管に接続する。更に、フランジ部材10の筒体部分13aを開口部2aに挿通し、段押し部2bの上面にフランジ部材10のフランジ部10aを収納した上で、フランジ部材10の雄ネジを、トラップ本体9の雌ネジに螺合させる。これにより、フランジ部材10のフランジ部10a下面と、トラップ本体9の凸部9b上面とで、洗濯機用防水パン1の開口部2aの周縁、即ち段押し部2bの底面2を挟持するようにして、トラップ本体9とフランジ部材10が、洗濯機用防水パン1に固定される。
更に床面F上に洗濯機用防水パン1を、ビスなどを使用して固定する。
この時、本実施例では、前述のように、段押し部2bの裏面の下端と、外側の周壁3の下端との上下方向の位置関係については、段押し部2bの裏面の下端の方が、少なくともトラップ本体9の凸部9bの上下方向の厚み分以上の幅を有して上方となるように構成されてなるため、床面Fに排水トラップTを配置するために設ける開口は、トラップ本体9の側面形状にのみ合わせて開口するだけで良い物となる。
簡単に説明すると、床面Fの開口と凸部9bの周縁との間に隙間が広く設けられていたり、凸部9bの下方に床面Fが存在しない状態であると、床下空間の通気などが凸部9bの隙間から洩れ、屋内側に不要な通気を生じて居住者に不快感を与えてしまう、等の問題を生じる。これを防止するために、従来例の場合、床面Fの開口は、トラップ本体9の側面に、更に凸部9bの周縁の開口に合わせて段を設ける二段形状にしなければならなかった。しかし、本第二実施例では、凸部9bが床面Fに食い込むことが無くなったため、床面Fを、トラップ本体9の凸部9bを除く側面形状にのみ合わせて開口するだけで良くなり、作業が簡易となった分、作業性を良い物とすることができる(側面に設けた排出口に対応するため、部分的に大きく切り拡げ、トラップ本体を取り付けた後に板材で余計な開口部分を塞ぐ場合があるが、図9では省略する)。
The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body 9 is provided on the floor surface F. Next, the discharge port 9a of the trap body 9 is connected to the sewage side pipe through this opening. Further, the tubular portion 13a of the flange member 10 is inserted into the opening 2a, and the flange portion 10a of the flange member 10 is accommodated on the upper surface of the stepped portion 2b. Screw onto the female screw. Accordingly, the lower surface of the opening 2a of the waterproof pan 1 for a washing machine, that is, the bottom surface 2 of the stepped portion 2b is sandwiched between the lower surface of the flange portion 10a of the flange member 10 and the upper surface of the convex portion 9b of the trap body 9. Thus, the trap body 9 and the flange member 10 are fixed to the waterproof pan 1 for a washing machine.
Further, the waterproof pan 1 for a washing machine is fixed on the floor surface F using screws or the like.
At this time, in this embodiment, as described above, regarding the vertical positional relationship between the lower end of the back surface of the step pressing portion 2b and the lower end of the outer peripheral wall 3, the lower end of the back surface of the step pressing portion 2b is The opening provided for disposing the drainage trap T on the floor F has a width equal to or greater than the thickness of the convex portion 9b of the trap body 9 in the vertical direction. It is sufficient to open only in accordance with the side shape of the main body 9.
Briefly, if there is a wide gap between the opening of the floor surface F and the peripheral edge of the convex portion 9b, or if the floor surface F does not exist below the convex portion 9b, ventilation in the underfloor space, etc. Leaks from the gap between the convex portions 9b, causing unnecessary ventilation on the indoor side and causing the occupant to feel uncomfortable. In order to prevent this, in the case of the conventional example, the opening of the floor surface F has to be formed in a two-stage shape in which a step is provided on the side surface of the trap body 9 in accordance with the opening on the periphery of the convex portion 9b. However, in the second embodiment, since the convex portion 9b does not bite into the floor surface F, it is only necessary to open the floor surface F according to only the side surface shape excluding the convex portion 9b of the trap body 9, Since the work is simplified, workability can be improved (to accommodate the discharge port provided on the side surface, it is partially enlarged, and after installing the trap body, an extra opening is made with a plate. (It is not shown in FIG.

次に、防臭筒13と封水椀12の内部に洗濯機用接続管16を収納した状態で、防臭筒13と封水椀12をツメ部13bにて係合させたことで構成した、接続管付き封水ユニット15を、フランジ部材10の開口部2aから挿通する。この後、封水椀12をフランジ部材10内部につり下げるようにして、トラップ本体9内部に配置すると共に、洗濯機用接続管16を内部に収納した防臭筒13の、上端のすり鉢状部分の外周部分を、フランジ部材10内面に対して水密的に接続する。
これにより、洗濯機用接続管16は、T字を上下逆転した状態にて、また、水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するようにして、排水トラップT内部に取り付けることができる。
この状態で、フランジ部材10の内部の開口が、排水口10bとして機能する。更に排水口10bに目皿部材11をセットし、エルボ管E等を利用し洗濯機用接続管16に洗濯機用排水ホースを接続した上で、足置き台4上に洗濯機Lの脚部を載置する。最後に、凹部5に壁部材8を水密的に取り付けて、洗濯機用防水パンと排水トラップ、及び洗濯機の施工が完了する。
Next, the connection configured by engaging the deodorizing cylinder 13 and the sealing water bottle 12 with the claw portion 13b in a state where the washing machine connection pipe 16 is housed inside the deodorizing cylinder 13 and the sealing water bottle 12. The sealed water unit 15 with a pipe is inserted through the opening 2 a of the flange member 10. Thereafter, the sealing tub 12 is suspended inside the flange member 10 so as to be disposed inside the trap body 9 and the mortar-shaped portion at the upper end of the deodorizing cylinder 13 housing the connecting pipe 16 for the washing machine inside. The outer peripheral portion is watertightly connected to the inner surface of the flange member 10.
As a result, the connecting pipe 16 for the washing machine is in a state in which the T-shape is turned upside down, and the ends of the horizontal tube part are slightly outside the outer surface of the cylinder part 13a of the deodorizing cylinder 13 at both ends. Can be attached to the inside of the drain trap T.
In this state, the opening inside the flange member 10 functions as the drain port 10b. Further, the eye plate member 11 is set in the drain port 10b, and the washing machine drain hose is connected to the washing machine connection pipe 16 using the elbow pipe E or the like, and the leg of the washing machine L is placed on the footrest 4. Is placed. Finally, the wall member 8 is watertightly attached to the recess 5 to complete the construction of the waterproof pan for the washing machine, the drain trap, and the washing machine.

上記のように構成された洗濯機用防水パンと排水トラップは、以下のようにして使用される。
洗濯機Lを使用し、洗濯機Lより排水が生じると、洗濯機Lからの排水は、洗濯機用排水ホースから、洗濯機用接続管16を介し、封水椀12内部に流入して溜まり、充分に溜まると封水椀12の側面に設けられた開口から溢れ出す。封水椀12から流出した排水は、トラップ本体9内部から排出口9aを介して下水側に排出される。この際、洗濯機用接続管16の水平な管体部分の端部は、両端とも防臭筒13の筒体部分13aの外側面よりも若干外側に突出するように構成されてなるため、洗濯機Lからの泡混じりの排水は、まず防臭筒13の筒体部分13aの外部にのみ排出され、防臭筒13の内部には排出されない。そして排水中の泡はその浮力により排水に対して浮き上がるから、防臭筒13の筒体部分13aの外部に排出された排水中の泡はそのまま防臭筒13外側面と封水椀12内側面の間を通過し、封水椀12側面の開口から下流側に排出され、防臭筒13内面から排水口10bに逆流することは無い。
また、洗濯機L自体や洗濯機用排水ホースの破損等により、洗濯機用防水パン1の底面2上に排水が生じると、排水は、洗濯機用防水パン1の底面2上を通過した上で、排水口10bの目皿部材11を通過し、防臭筒13内部、封水椀12内部、封水椀12の上方の開口、トラップ本体9内部、排出口9a、の順に通過し、最終的に下水側に排出される。
尚、周壁3の凹部5には、壁部材8が水密的に取り付けられているため、洗濯機用防水パン1内部に排水が生じても、周壁3の上端にまで排水が溜まらない限り、排水が洗濯機用防水パン1内部より溢れ出る事はない。
また、上記のように構成した排水トラップTにおいて、洗濯機用接続管16又は排水口10bを介し、排水トラップT内に排水が行われると、封水椀12内部に、側面の開口の下端の高さまで排水が溜まる。これにより、排水口10b又は洗濯機用接続管16から封水椀12の側面の開口部2a下端までの流路に、排水で満たされた部分が形成される。この溜まった排水を封水と呼び、下水側から臭気や害虫類が屋内側に侵入しようとしても、この封水によってそれ以上屋内側に侵入されることを防止ることができる。このように、下水側から臭気や害虫類が屋内側に侵入することを防止する機能をトラップ機能と呼ぶ。
The washing machine waterproof pan and drain trap configured as described above are used as follows.
When the washing machine L is used and drainage is generated from the washing machine L, the drainage from the washing machine L flows from the washing machine drain hose through the washing machine connection pipe 16 into the sealed water bottle 12 and accumulates. When it is sufficiently collected, it overflows from the opening provided on the side surface of the sealing tub 12. The waste water that has flowed out of the sealing tub 12 is discharged from the inside of the trap body 9 to the sewage side through the discharge port 9a. At this time, since the ends of the horizontal tube portion of the connecting pipe 16 for the washing machine are configured so that both ends protrude slightly outward from the outer surface of the tube portion 13a of the deodorizing tube 13, the washing machine The bubble-mixed waste water from L is first discharged only to the outside of the cylindrical portion 13 a of the deodorizing cylinder 13 and is not discharged to the inside of the deodorizing cylinder 13. Since the bubbles in the drainage are lifted with respect to the drainage by the buoyancy, the bubbles in the drainage discharged to the outside of the cylindrical portion 13a of the deodorizing cylinder 13 are directly between the outer surface of the deodorizing cylinder 13 and the inner surface of the sealing tub 12. And is discharged downstream from the opening on the side surface of the sealing tub 12 and does not flow backward from the inner surface of the deodorizing cylinder 13 to the drain port 10b.
Further, when drainage occurs on the bottom surface 2 of the washing machine waterproof pan 1 due to damage to the washing machine L itself or the washing machine drain hose, the drainage passes over the bottom surface 2 of the washing machine waterproof pan 1. Then, it passes through the eye plate member 11 of the drain port 10b, passes in the order of the inside of the deodorizing cylinder 13, the inside of the sealed water bottle 12, the opening above the sealed water bottle 12, the inside of the trap body 9 and the discharge port 9a. Discharged to the sewage side.
In addition, since the wall member 8 is watertightly attached to the recess 5 of the peripheral wall 3, even if drainage occurs inside the waterproof pan 1 for a washing machine, as long as the drainage does not accumulate at the upper end of the peripheral wall 3, Does not overflow from the inside of the waterproof pan 1 for a washing machine.
Further, in the drain trap T configured as described above, when drainage is performed in the drain trap T via the washing machine connection pipe 16 or the drain port 10b, the bottom end of the side opening is placed inside the sealing tub 12. Drainage collects up to the height. Thus, a portion filled with drainage is formed in the flow path from the drain outlet 10b or the connecting pipe 16 for the washing machine to the lower end of the opening 2a on the side surface of the sealing tub 12. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

上記のように構成した第二実施例の洗濯機用防水パンと排水トラップにおいて、長期間の使用により、排水トラップT内部に汚れが付着して異臭を生じたり、堆積した毛髪や糸くず等の塵芥、汚れ成分などで管詰まりが生じ、排水トラップTの内部を清掃する必要が生じた場合、以下の方法にて排水トラップTの部材を取り出し、清掃することができる。
まず凹部5から壁部材8を取り外し、周壁3内部に作業者の手を挿入できる隙間空間を確保する。
次に、切り欠きを拡径して、洗濯機用接続管16又は洗濯機用排水ホースから目皿部材11を取り外し、段部6、凹部5を介して周壁3の外部に取り出す。
次に、洗濯機用接続管16と洗濯機用排水ホースとの接続を解除した上で、防臭筒13とフランジ部材10との接続を解除する。
その後、接続管付き封水ユニット15を周壁3の外部に取り出す。
この排水トラップTの部材の取り出し作業に際して、清掃作業の作業者は、接続管付き封水ユニット15を取り出す際、以下に記載した理由4.乃至理由6.の理由により、底部の開口部2a(本実施例の場合にはフランジ部材10内部の排水口10b)より接続管付き封水ユニット15を上方に取り出し、図16に示したように、そのまま傾斜させることなく水平に移動させて、凹部5より取り出し作業を行う事となる。よって、底面2上に封水椀12内の封水(排水)がこぼれることがほぼ確実に無くなる。
理由4.本実施例においては、封水椀12の縦幅は封水椀12の横幅よりも短く、また防臭筒13の縦幅は封水椀12の横幅よりも短く、また封水ユニット14においても排水ユニットの縦幅は排水ユニットの横幅より短く構成してなる(接続管付き封水ユニット15の状態においては、縦幅と横幅はほぼ同一で、若干縦幅の方が短い)。
このため、従来例のように、封水椀12や防臭筒13(特に封水椀12)を傾斜させることにメリットは無く、傾斜させずに水平に移動させて周壁3から取り出す方が好適になるように構成してなる。
理由5.封水椀12、防臭筒13、及び凹部5の各下端部分、特に接続管付き封水ユニット15において下端となる封水椀12の下端部分を、側面視略水平状となるように構成してなる。これにより、接続管付き封水ユニット15を凹部5から取り出す際、接続管付き封水ユニット15を傾斜することなく取り出すガイドとして機能し、接続管付き封水ユニット15を構成する防臭筒13、封水椀12等の部材が横方向に傾斜するのを防ぐ効果を奏する。
理由6.接続管付き封水ユニット15において、洗濯機用接続管16の中央の垂直な管体を摘むようにし、そのまま上方に引き上げると、洗濯機用接続管16の水平な管体部分の両端に防臭筒13が載架した状態となり、且つツメ部13b材により防臭筒13と封水椀12が係合した状態であることから、接続管付き封水ユニット15の各部材を水平状体を維持したまま容易に引き上げることができる。この時、防臭筒13、封水椀12、及び洗濯機用接続管16の接続はいずれも固定的なものではなく、単に載架・遊びを有しての係合程度のものでしかないため、洗濯機用接続管16の中央の垂直な管体を摘んで傾斜させようとしても封水椀12の封水が錘のように作用して作業者の思うように傾斜させることができない。
結果、清掃作業者は、封水ユニット14を移動させる際は、封水ユニット14を傾斜させることなく、洗濯機用接続管16の中央の垂直な管体を摘んで、水平状態を維持したまま、移動させる事となる。
In the waterproof pan and drainage trap for the washing machine of the second embodiment configured as described above, due to long-term use, dirt adheres to the inside of the drainage trap T, and a strange odor is produced, such as accumulated hair and lint. When pipe clogging occurs due to dust, dirt components, etc., and it becomes necessary to clean the inside of the drain trap T, the member of the drain trap T can be taken out and cleaned by the following method.
First, the wall member 8 is removed from the recess 5 to secure a clearance space in which the operator's hand can be inserted into the peripheral wall 3.
Next, the diameter of the notch is expanded, the eye plate member 11 is removed from the washing machine connecting pipe 16 or the washing machine drain hose, and taken out to the outside of the peripheral wall 3 through the step 6 and the recess 5.
Next, the connection between the washing machine connection pipe 16 and the washing machine drain hose is released, and then the connection between the deodorizing cylinder 13 and the flange member 10 is released.
Thereafter, the sealing unit with connection pipe 15 is taken out of the peripheral wall 3.
When the member of the drain trap T is taken out, the cleaning operator takes the reason described below when taking out the sealing unit 15 with a connecting pipe. To reason 6 For this reason, the sealing unit with connection pipe 15 is taken out from the opening 2a at the bottom (in the case of the present embodiment, the drain port 10b inside the flange member 10), and is tilted as it is as shown in FIG. It is moved horizontally without taking out from the recess 5. Therefore, the sealed water (drainage) in the sealed water tub 12 is almost certainly not spilled on the bottom surface 2.
Reason 4 In the present embodiment, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, the vertical width of the deodorizing cylinder 13 is shorter than the horizontal width of the sealed water jar 12, and the sealed water unit 14 is also drained. The vertical width of the unit is configured to be shorter than the horizontal width of the drainage unit (in the state of the sealing unit 15 with connecting pipe, the vertical width and the horizontal width are substantially the same, and the vertical width is slightly shorter).
For this reason, there is no merit in inclining the sealed water bottle 12 or the deodorizing cylinder 13 (especially the sealed water bottle 12) as in the conventional example, and it is preferable to move it horizontally without taking it out and to take it out from the peripheral wall 3. It is comprised so that.
Reason 5. The bottom end of each of the water seal 12, the deodorizing cylinder 13, and the recess 5, particularly the bottom end of the water seal 12 that is the lower end of the water seal unit 15 with a connecting pipe is configured to be substantially horizontal when viewed from the side. Become. Thus, when the sealing unit with connection pipe 15 is taken out from the recess 5, it functions as a guide for taking out the sealing unit with connection pipe 15 without tilting, and the deodorizing cylinder 13 constituting the sealing unit with connection pipe 15, sealing There exists an effect which prevents that members, such as the water tank 12, incline to a horizontal direction.
Reason 6 In the sealing unit 15 with connecting pipe, when the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and pulled up as it is, the deodorizing cylinders are attached to both ends of the horizontal pipe portion of the connecting pipe 16 for the washing machine. Since the deodorizing cylinder 13 and the sealing tub 12 are engaged by the claw portion 13b, the members of the sealing unit with a connecting pipe 15 are maintained in a horizontal state. Can be pulled up easily. At this time, the connection of the deodorizing cylinder 13, the water seal 12 and the connecting pipe 16 for the washing machine is not fixed and is merely an engagement degree with mounting and play. Even if the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and tilted, the sealing water of the sealing tub 12 acts like a weight and cannot be tilted as desired by the operator.
As a result, when the cleaning operator moves the sealing unit 14, the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and maintained in a horizontal state without tilting the sealing unit 14. Will be moved.

このようにして排水トラップTから部材を取り出し、清掃を行った後、また場合によってはトラップ本体9内部の清掃や、排出口9aから下流側の配管の清掃作業/管詰まりの解消を、機材などを凹部5また排水口10bを介して作業を行い、清掃作業/管詰まりの解消を行った後、段落0028に記載の、洗濯機Lを洗濯機用防水パン1に載置する以外の作業を繰り返すことで、排水トラップTの部材の取り付け作業を完了させ、排水トラップTの清掃作業が完了する。 After removing the member from the drain trap T and cleaning it in this way, in some cases, cleaning the inside of the trap body 9 or cleaning the pipe downstream from the discharge port 9a / resolving clogging of the equipment, etc. After performing the work through the recess 5 and the drain port 10b to perform cleaning work / clogging of the pipe, work other than placing the washing machine L on the waterproof pan 1 for the washing machine described in paragraph 0028 is performed. By repeating, the attachment operation | work of the member of the drain trap T is completed, and the cleaning operation | work of the drain trap T is completed.

本発明の実施例は以上のようであるが、本発明は上記実施例に限定される物ではなく、主旨を変更しない範囲において自由に変更が可能である。
例えば上記第二実施例においては、段部6を有さない洗濯機用防水パン1に、封水椀12と防臭筒13とが係合することで封水ユニット14となる排水トラップTを採用してなるが、本発明は上記実施例に限定されるものではなく、段部6を有さない洗濯機用防水パン1に、封水椀12と防臭筒13とが係合しない排水トラップTを採用しても良い。この場合でも理由1.、理由2.(又は理由4.及び理由5.)により、この排水トラップTの部材の取り出し作業に際して、清掃作業の作業者は、接続管付き封水ユニット15を取り出す際、底部の開口部2aより防臭筒13、封水椀12等の排水トラップTの部材を上方に取り出し、そのまま傾斜させることなく水平に移動させて、凹部5より取り出し作業を行う事となる。よって、底面2上に封水椀12内の封水(排水)がこぼれることがほぼ確実に無くなる。
The embodiments of the present invention are as described above. However, the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention.
For example, in the second embodiment, the drainage trap T that becomes the sealing unit 14 by engaging the sealing jar 12 and the deodorizing cylinder 13 with the waterproof pan 1 for a washing machine that does not have the stepped portion 6 is adopted. However, the present invention is not limited to the above embodiment, and the drain trap T in which the sealing tub 12 and the deodorizing cylinder 13 are not engaged with the waterproof pan 1 for a washing machine not having the stepped portion 6. May be adopted. Even in this case, Reason 1. Reason 2 (Or Reason 4. and Reason 5.), when the member of the drain trap T is taken out, the worker of the cleaning work takes out the deodorizing cylinder 13 from the opening 2a at the bottom when taking out the sealing unit 15 with the connecting pipe. Then, the member of the drain trap T such as the sealing tub 12 is taken out upward, moved as it is without being inclined, and taken out from the recess 5. Therefore, the sealed water (drainage) in the sealed water tub 12 is almost certainly not spilled on the bottom surface 2.
