Description

本発明は、洗濯機からの排水を排出する洗濯機排水配管を、下流側の配管に接続する為の配管接続口を備えた、洗濯機用防水パンに関するものである。 The present invention relates to a waterproof pan for a washing machine provided with a pipe connection port for connecting a washing machine drain pipe for discharging waste water from the washing machine to a downstream pipe.

従来より、洗濯機を配置する場合に、洗濯機からの配管を下流側の配管に接続するための配管接続口を備えた洗濯機用防水パンを用いる方法が知られている。
特許文献１に記載した洗濯機用防水パンは、排水トラップを備えた底壁部と、該底壁部の周囲に設けた側壁部と、底壁部の四隅に設けた架台部と、からなる。この洗濯機用防水パンを床面上に設置し、架台部分の上に洗濯機の脚部を配置すると共に、排水トラップに備えられた配管接続口に洗濯機からの配管を接続することで、洗濯機からの配管を洗濯機用防水パンの底壁部裏側の配管に接続するように構成してなる。即ち、配管接続口は洗濯機用防水パンの表側と裏側とを貫通するように設けられてなる。
特許文献１に記載した従来例では、洗濯機用防水パンの底壁部に、洗濯機用防水パンの表側と裏側とを貫通する開口を設け、この開口に排水トラップを接続した上で、排水トラップに配管接続口を設けることで、洗濯機からの配管を、洗濯機用防水パンの底壁部裏側の配管に接続するように構成されてなる。 Conventionally, when a washing machine is arranged, a method using a waterproof pan for a washing machine provided with a pipe connection port for connecting a pipe from the washing machine to a downstream pipe is known.
The waterproof pan for a washing machine described in Patent Document 1 includes a bottom wall portion provided with a drain trap, a side wall portion provided around the bottom wall portion, and a pedestal portion provided at four corners of the bottom wall portion. . By installing this washing machine waterproof pan on the floor, placing the legs of the washing machine on the pedestal part, and connecting the pipe from the washing machine to the pipe connection port provided in the drain trap, The pipe from the washing machine is configured to be connected to the pipe on the back side of the bottom wall of the waterproof pan for the washing machine. That is, the pipe connection port is provided so as to penetrate the front side and the back side of the waterproof pan for a washing machine.
In the conventional example described in Patent Document 1, an opening that penetrates the front and back sides of the waterproof pan for washing machine is provided in the bottom wall portion of the waterproof pan for washing machine, and a drain trap is connected to the opening. By providing the pipe connection port in the trap, the pipe from the washing machine is connected to the pipe on the back side of the bottom wall portion of the waterproof pan for the washing machine.

また、特許文献２に記載の洗濯機用防水パンは、洗濯機の配管と、下流側の配管の接続を行うと共に、接続箇所の漏水等を受ける防水パンであって、排水トラップを備えた底壁部と、該底壁部の周囲に設けた側壁部と、からなる。この洗濯機用防水パンにおいては、底壁部の下端は、接続されている排水トラップの下端よりも下方にあり、このため排水トラップは床面上に設置され、排水トラップからの配管、即ち配管接続口から下流側となる配管も床面上に配置されるように構成されてなる。
リフォーム等を行う際、洗濯機の配置をリフォーム前から変更しようとすると、床下の洗濯機排水配管が利用できなくなったり、または床下配管をやり直す大規模な工事が必要となる場合がある。しかし、この特許文献２に記載の洗濯機用防水パンでは、床面上に洗濯機用防水パンと配管接続口から下流側となる配管を配置する構成であり、また洗濯機の載置を行わないことを前提とした構成のため、リフォームに際して、洗濯機を床下配管とは関係ない任意の位置に配置し、また洗濯機用防水パンとそれよりも下流側の配管も洗濯機や床下配管と関係ない任意の位置に配置することができる。 A waterproof pan for a washing machine described in Patent Document 2 is a waterproof pan that connects a pipe of a washing machine to a downstream pipe and receives water leakage at a connection location, and has a bottom provided with a drain trap. It consists of a wall part and a side wall part provided around the bottom wall part. In this waterproof pan for a washing machine, the lower end of the bottom wall portion is below the lower end of the connected drain trap, and for this reason, the drain trap is installed on the floor surface. The piping on the downstream side from the connection port is also configured to be arranged on the floor surface.
When performing the renovation or the like, if it is attempted to change the arrangement of the washing machine before the renovation, the underfloor washing machine drainage pipe may become unavailable, or a large-scale construction may be required to redo the underfloor pipe. However, the waterproof pan for a washing machine described in Patent Document 2 has a configuration in which a waterproof pan for a washing machine and a pipe downstream from the pipe connection port are arranged on the floor surface, and the washing machine is placed. Therefore, when renovating, the washing machine is placed in any position not related to the underfloor piping, and the waterproof pan for the washing machine and the downstream piping are also connected to the washing machine and the underfloor piping. It can be placed at any unrelated position.

上記のような従来の洗濯機用防水パンには、以下に記載するような問題点があった。
前述のように、リフォームによって濯機用防水パンを新たに配置する場合に、特許文献２の洗濯機用防水パンのように、配管接続口よりも下流側の配管を床面上に配置すると、家具や機器等の設置に配管が邪魔になるため、できれば床下配管を利用して設置したい、という要望がある。
リフォームの際に、全く新しく床下に排水配管を設置し直すことは困難であっても、床面に新たな開口を設け、既設の床下の排水配管からチーズ管やエルボ管等を利用して排水配管を分岐させ、床面の新たな開口の位置に配管の端部を配置するような、単に配管を接続させ任意の位置に配置するだけの作業であれば、比較的容易に行うことができる。
図７及び図８はこのようなリフォーム時の床下配管の一例を示すものである。図７はリフォーム前の床下配管を、図８はリフォーム後の床下配管を説明する参考図である。
既設の配管ＥＰ１は、ガス配管や給湯配管など、リフォームの前後で変更の無い配管である。また、排水配管についても、既設の排水配管ＥＰ２として示した部分は排水主管とその付近の配管であり、リフォームの前後でそのまま使用する排水配管である。尚、図７、図８では、既設の配管ＥＰ１、及び既設の排水配管ＥＰ２の排水主管は、その管体を軸方向視しているものである。
また、この図７、図８の事例では、床面に設ける床下配管の接続用の端部について、リフォーム後の位置は、リフォーム前よりも図面左側に設置位置を変更するものである。
前述のように、床下には排水配管の他に、給水用の配管、都市ガスの配管等、他の機器の配管など既設の配管ＥＰ１が既に配管されている場合が多く、上記のように床下の排水配管を分岐させる場合には、分岐した排水配管がこれら既設の配管ＥＰ１に干渉しないように施工を行う必要がある。
しかし、排水配管は通常勾配を利用して排水を行うため、上記のように他の既設の配管を避けて施工を行う場合に、新たに施工する排水配管部分が、他の配管の下側を通して迂回するように施工すると、逆勾配となってしまう恐れがある。例えば、図８の床下配管の場合、点線で示したように、既設の排水配管ＥＰ２をそのまま水平方向に延長すると、既設の配管ＥＰ１に干渉してしまい、施工できない、または逆勾配となってしまう。
即ち、先述のように、技術的・作業的には既設の排水配管から新たに分岐した排水配管を配管することは比較的容易であるが、床下に配置された他の既設配管を迂回しつつ、且つ排水勾配を確保した配管レイアウトを組むことが極めて困難である、という問題があった。
排水勾配を確保するため、図８に示した床下配管のように、新たに施工する排水配管部分が、他の配管の上側を迂回するように施工できれば、上記逆勾配の問題は解決できるが、このためには、新たに施工する排水配管の、床下空間の端部部分が、なるべく床面の裏側近くの高い位置で略水平方向を向いていることが必要である。
しかし、特許文献１に記載の洗濯機用防水パンのように、底壁部に開口を設け、この開口に排水トラップやエルボ管を固定する構成の洗濯機用防水パンでは、底壁部の開口に排水トラップやエルボ管を固定するためのネジ等の固定機構や接着を行う場合の接着しろが配置され、これらの機構部分では管体を直線形状としなければならない。
そして、洗濯機用防水パンの底壁部と、床面の開口とはほぼ同じ高さ位置となるように配置される。
つまり、床面の開口部近傍では、排水トラップやエルボ管を洗濯機用防水パンに取り付ける固定機構や接着しろが配置され、配管を鉛直方向に直線形状としなければならず、床面の裏側近くの高い位置で配管を屈曲させ略水平方向とすることは困難である。
また、配管接続の際、排水トラップを含む配管は床下空間に配置されるため、施工時に配管を目視しながら作業することができず、洗濯機用防水パンの施工は困難なものとなりがちであった。
また、リフォームの際、床上配管を行う場合においても、次のような問題があった。
排水配管のみならず、ガス配管など床下配管の配管レイアウトなどを設計段階から調整できる新築の場合は床下配管が行われ、床上配管が採用されることはほとんど無い。つまり床上配管はほぼリフォームの場合にのみ採用される配管レイアウトであるが、リフォームの件数は新築ほど多くないため、リフォーム専用の洗濯機用防水パンである床上配管用の洗濯機用防水パンは生産数が少なく、その分大量生産によるコストダウンが困難であった。
本発明は上記問題点に鑑み発明されたものであって、洗濯機用防水パンを設置した床面の開口の近傍から配管を水平方向に延出でき、また水平方向への延出の高さ位置の調整が可能で、施工時の配管接続も目視によって確認でき、且つ床上配管に対応した洗濯機用防水パンを安価とすることができる洗濯機用防水パンを提供するものである。 The conventional waterproof pan for a washing machine as described above has the following problems.
As described above, when a waterproof pan for a rinsing machine is newly arranged by renovation, as in the case of the waterproof pan for a washing machine of Patent Document 2, if a pipe downstream from the pipe connection port is arranged on the floor surface, furniture is obtained. Since piping is an obstacle to the installation of equipment and equipment, there is a desire to install it using underfloor piping if possible.
Even if it is difficult to re-install the drainage pipe under the floor at the time of renovation, a new opening is provided in the floor, and drainage is made from the existing underfloor drainage pipe using a cheese pipe or an elbow pipe. If the work is simply to connect the pipe and place it at any position, such as branching the pipe and placing the end of the pipe at the position of the new opening on the floor, it can be done relatively easily .
7 and 8 show an example of the underfloor piping at the time of such reforming. FIG. 7 is a reference diagram for explaining the underfloor piping before reforming, and FIG. 8 is a reference diagram for explaining the underfloor piping after reforming.
The existing pipe EP1 is a pipe that does not change before and after the renovation, such as a gas pipe or a hot water supply pipe. As for the drainage pipe, the part shown as the existing drainage pipe EP2 is a drainage main pipe and a pipe in the vicinity thereof, and is a drainage pipe that is used as it is before and after reforming. In FIGS. 7 and 8, the drainage main pipes of the existing pipe EP1 and the existing drainage pipe EP2 are obtained by viewing the pipes in the axial direction.
Moreover, in the case of this FIG. 7, FIG. 8, about the edge part for connection of the underfloor piping provided in a floor surface, the position after renovation changes an installation position to the left side of drawing rather than before renovation.
As described above, in addition to drainage pipes, existing pipes EP1 such as water supply pipes, city gas pipes, and other equipment pipes are often already piped under the floor. When branching the drainage pipe, it is necessary to perform construction so that the branched drainage pipe does not interfere with these existing pipes EP1.
However, because drainage pipes normally drain using a gradient, when construction is performed avoiding other existing pipes as described above, the newly constructed drainage pipe part passes through the lower side of the other pipes. If it is constructed so as to detour, there is a risk that it will have a reverse gradient. For example, in the case of the underfloor piping of FIG. 8, if the existing drainage pipe EP2 is extended in the horizontal direction as it is, as shown by the dotted line, it interferes with the existing pipe EP1 and cannot be constructed or has a reverse gradient. .
That is, as described above, it is relatively easy to pipe a drain pipe that is newly branched from an existing drain pipe in terms of technology and work, but while bypassing other existing pipes arranged under the floor. In addition, there is a problem that it is extremely difficult to construct a piping layout that ensures a drainage gradient.
In order to ensure the drainage gradient, if the drainage pipe part to be newly constructed can be constructed so as to bypass the upper side of other pipes like the underfloor pipe shown in FIG. 8, the above problem of reverse slope can be solved, For this purpose, it is necessary that the end portion of the underfloor space of the drainage pipe to be newly constructed is oriented in a substantially horizontal direction at a high position as close as possible to the back side of the floor surface.
However, as in the waterproof pan for a washing machine described in Patent Document 1, an opening in the bottom wall is provided in the waterproof pan for a washing machine having an opening in the bottom wall and a drain trap or an elbow pipe fixed to the opening. A fixing mechanism such as a screw for fixing the drain trap and the elbow pipe and an adhesive margin for bonding are arranged, and the pipe body must be formed into a straight shape in these mechanism portions.
And the bottom wall part of the waterproof pan for washing machines and the opening of a floor surface are arrange | positioned so that it may become the substantially same height position.
In other words, in the vicinity of the opening on the floor surface, a fixing mechanism for attaching the drain trap or elbow pipe to the waterproof pan for the washing machine and an adhesive margin are arranged, and the pipe must be straight in the vertical direction, near the back side of the floor surface. It is difficult to bend the pipe at a high position so that it is substantially horizontal.
Also, when connecting pipes, pipes including drain traps are placed under the floor, so it is difficult to work while visually observing the pipes during construction, and construction of waterproof pans for washing machines tends to be difficult. It was.
In addition, there are the following problems even when performing on-floor piping during renovation.
In the case of a new construction that can adjust not only the drainage piping but also the piping layout of the underfloor piping such as gas piping from the design stage, the underfloor piping is performed, and the floor piping is rarely adopted. In other words, the piping on the floor is a piping layout that is adopted only in the case of renovation, but the number of renovations is not as large as in the new construction, so the waterproof pan for the washing machine for the floor piping, which is a waterproof pan for the renovation dedicated washing machine, is produced. The number was small, and it was difficult to reduce the cost by mass production.
The present invention has been invented in view of the above problems, and can extend a pipe in the horizontal direction from the vicinity of the opening on the floor surface where the waterproof pan for a washing machine is installed, and the height of the extension in the horizontal direction. The present invention provides a waterproof pan for a washing machine that can be adjusted in position, can be visually checked for piping connection during construction, and can be made cheaper for a waterproof pan for a washing machine that supports floor piping.

請求項６に記載の本発明は、洗濯機Ｓの排水を処理するための洗濯機用防水パンであって、
底壁部２と、該底壁部２の周囲に設けた側壁部３と、床下配管から床面Ｆ上に延出された縦配管ＦＰと、洗濯機Ｓからの配管である洗濯機排水配管１１が接続されると共に、洗濯機用防水パン１の裏側の空間にて縦配管ＦＰと接続する配管接続部５と、から構成されることを特徴とする洗濯機用防水パンである。 The present invention according to claim 6 is a waterproof pan for a washing machine for treating drainage of the washing machine S,
A bottom wall 2, a side wall 3 provided around the bottom wall 2, a vertical pipe FP extending from the underfloor pipe onto the floor surface F, and a washing machine drain pipe that is a pipe from the washing machine S 11 is connected to the vertical pipe FP in the space on the back side of the waterproof pan 1 for a washing machine, and is a waterproof pan for a washing machine.

請求項１に記載の本発明においては、洗濯機用防水パンの底壁部よりも高い位置に配管接続部を設けたことで、底壁部よりも高い位置に、排水トラップやエルボ管を固定するためのネジ等の固定機構や接着を行う場合の接着しろを配置することができる。このため、洗濯機用防水パンの底壁部の裏面やその近傍である床面の開口の近傍で排水接続口からの配管（以下、この洗濯機用防水パンの排水接続口よりも下流側となる配管を「パン排水配管」と記載する）を水平方向に屈曲させることが可能となり、パン排水配管が他の配管の上側を通して迂回するように施工することが容易となった。
尚、上記構造であれば、配管接続部の下方側に接続する縦方向の配管の長さを調整すれば、床下空間の任意の高さで配管を水平方向に屈曲させることが可能であり、必ずしも床面の開口の近傍の高さ位置に限定して配管を水平方向に屈曲させる必要は無い。前述のように、床面の開口近傍でパン排水配管を水平方向に屈曲させる方が、排水の為の勾配を確保しやすいが、既設の配管を迂回するためには、床面の開口近傍以外の高さ位置で水平方向に屈曲させる場合もある。本発明は「パン排水配管を、床面の開口近傍に固定して水平方向に屈曲させる発明」では無く、「パン排水配管を、床面の開口近傍を含む任意の高さ位置に調整して水平方向に屈曲させることができる発明」である。
また、配管接続部が、底壁部に対して充分に高い位置にあれば、洗濯機用防水パンを設置した床面よりも高い位置でパン排水配管を水平方向に屈曲させることができる。このため、洗濯機用防水パン内部に溜まった排水が漏水しないように工夫した上で、請求項２に記載したように、パン排水配管を側壁部より延出すれば、パン排水配管を床上配管とした構造に対応することもできる。これにより、床上配管用の洗濯機用防水パンを、床下配管用の洗濯機用防水パンと同じ程度に安価とすることができる。
請求項３に記載の本発明では、接続筒部の側面から側壁部まで、その内部にパン排水配管を覆う配管カバー部を備えたことで、側壁部にパン排水配管を貫通させるための穴を設ける必要が無くなる。このため、洗濯機用防水パン内に溜まった排水があっても、洗濯機用防水パンの外部に漏水することが無い。
請求項４に記載の本発明においては、サイホン効果を利用して排水を効率よく行うことができるとともに、床上配管の場合においては、サイホン効果を利用してパン排水配管の一
部が配管接続部より高い位置にあっても支障なく排水を行うことができる。
請求項５に記載の本発明においては、洗濯機用防水パン内部に溜まった排水を、支障なく排出することができる。
請求項６に記載の本発明においては、床下配管と洗濯機用防水パンとの配管接続において、洗濯機用防水パンのパン排水配管との接続は、床面上に突出した縦配管に対して行われ、配管接続の状況を視認できるため、床下空間において洗濯機用防水パンとパン排水配管とを接続する場合に比べ容易に接続を行うことができる。 In this invention of Claim 1, a drainage trap and an elbow pipe are fixed to a position higher than a bottom wall part by providing a pipe connection part in a position higher than the bottom wall part of the waterproof pan for washing machines. It is possible to dispose a fixing mechanism such as a screw or a bonding margin for bonding. For this reason, piping from the drainage connection port in the vicinity of the back surface of the bottom wall of the waterproof pan for washing machine and the opening of the floor surface in the vicinity thereof (hereinafter referred to as the downstream side of the drainage connection port of the waterproof pan for washing machine) It is possible to bend the pipe in the horizontal direction, and it is easy to construct the pan drain pipe so that it bypasses the other pipe.
In the case of the above structure, if the length of the vertical pipe connected to the lower side of the pipe connection part is adjusted, the pipe can be bent in the horizontal direction at an arbitrary height in the underfloor space. It is not always necessary to bend the pipe in the horizontal direction only at a height position near the opening on the floor surface. As mentioned above, it is easier to ensure the slope for drainage by bending the pan drainage pipe in the horizontal direction near the floor opening, but in order to bypass the existing pipe, There is also a case where it is bent in the horizontal direction at the height position. The present invention is not “an invention in which the pan drain pipe is fixed in the vicinity of the floor surface opening and bent horizontally”, but “the pan drain pipe is adjusted to an arbitrary height position including the vicinity of the floor surface opening. An invention that can be bent horizontally.
Further, if the pipe connection portion is at a sufficiently high position with respect to the bottom wall portion, the pan drainage pipe can be bent in the horizontal direction at a position higher than the floor surface on which the waterproof pan for a washing machine is installed. For this reason, after devising so that the waste water collected inside the waterproof pan for washing machines does not leak, as described in claim 2, if the pan drain pipe is extended from the side wall, the pan drain pipe is connected to the floor pipe. It can also correspond to the structure. Thereby, the waterproof pan for washing machines for floor piping can be made inexpensive as much as the waterproof pan for washing machines for floor piping.
In this invention of Claim 3, by providing the pipe cover part which covers bread | pan drainage piping in the inside from the side surface of a connection cylinder part to a side wall part, the hole for making bread | pan drainage piping penetrate in a side wall part is provided. There is no need to provide it. For this reason, even if there is drainage accumulated in the waterproof pan for washing machines, water does not leak outside the waterproof pan for washing machines.
In the present invention according to claim 4, drainage can be efficiently performed using the siphon effect, and in the case of floor piping, a part of the pan drainage pipe is connected to the pipe connection portion using the siphon effect. Even if it is in a higher position, drainage can be performed without any problem.
In this invention of Claim 5, the waste_water | drain collected in the waterproof pan for washing machines can be discharged | emitted without trouble.
In this invention of Claim 6, in the piping connection of underfloor piping and the waterproofing pan for washing machines, the connection with the pan drainage piping of the waterproofing pan for washing machines is connected to the vertical piping protruding on the floor surface. Since the state of the pipe connection can be visually confirmed, the connection can be easily performed as compared with the case where the waterproof pan for the washing machine and the pan drain pipe are connected in the underfloor space.

設置する床面Ｆには、平面視において洗濯機用防水パン１よりも小さい大きさの床面の開口ＦＯが設けられてなり、この床面の開口ＦＯから床下配管に繋がる塩ビ素材の縦配管ＦＰが垂立して備えられてなる。
この縦配管ＦＰについて詳述すると、上記のようにリフォームを行うに際し、洗濯機用防水パン１を任意の箇所に設置するため、設置個所の床面Ｆに開口を設け、この床面の開口ＦＯから垂立するように床下の既設の排水配管ＥＰ２から分岐させたものである。この際、図８に示したように、開口の位置にて縦配管ＦＰを床面Ｆ上に延出しつつ、且つ既設の給水管やガス配管等の既設の配管ＥＰ１を迂回しながら床下配管の主管まで自然排水の勾配を確保するために、既設の配管ＥＰ１の上側を迂回して配管している。このため、縦配管ＦＰは床面の開口ＦＯ近傍にエルボ管を配置しており、エルボ管の端部に設けたソケット部ＰＳ（縦配管ＦＰとなる直管端部を収納し、接着する際の接着しろとなる部分）は床面の開口ＦＯと同じ高さ、または床面よりも上方の位置に達している。これらの配管は、以下に記載する洗濯機用防水パン１の施工を開始する際に、既に配管作業が完了しており、各接続部分は必要に応じ、接着などの方法で水密的に接続固定されている。また縦配管ＦＰは、後述する洗濯機用防水パン１を接続するのに適切な高さになるよう、その長さを調整した上で配置されている。
尚、図示また詳細な記載等は省くが、これらの配管は、必要に応じて、床面Ｆよりも下方のコンクリート打設面に支持具などで位置決め固定され、水平方向／垂直方向に対し固定されている。 The floor surface F on which the waterproof pan 1 for the washing machine is installed has the following piping structure.
The floor surface F to be installed is provided with a floor surface opening FO having a size smaller than that of the waterproof pan 1 for a washing machine in a plan view, and a vertical piping made of a PVC material that leads from the floor surface opening FO to the underfloor piping. The FP is provided vertically.
The vertical pipe FP will be described in detail. When the renovation is performed as described above, the waterproof pan 1 for a washing machine is installed at an arbitrary place. It is branched from the existing drainage pipe EP2 under the floor so as to be suspended from the floor. At this time, as shown in FIG. 8, the vertical pipe FP is extended on the floor surface F at the position of the opening, and the existing pipe EP1 such as the existing water supply pipe or gas pipe is bypassed while bypassing the underfloor pipe. In order to ensure the gradient of natural drainage to the main pipe, the pipe is bypassed above the existing pipe EP1. For this reason, the vertical pipe FP has an elbow pipe disposed in the vicinity of the opening FO on the floor surface, and the socket part PS provided at the end of the elbow pipe (when the straight pipe end part to be the vertical pipe FP is accommodated and bonded) The portion to be bonded) reaches the same height as the opening FO on the floor surface or a position above the floor surface. These pipes have already been completed when construction of the waterproof pan 1 for a washing machine described below is started, and each connection portion is connected and fixed in a watertight manner by bonding or the like, if necessary. Has been. The vertical pipe FP is arranged after adjusting its length so as to have an appropriate height for connecting a waterproof pan 1 for a washing machine to be described later.
In addition, although illustration and detailed description etc. are omitted, these pipes are positioned and fixed to the concrete placing surface below the floor surface F with a support tool or the like as necessary, and fixed in the horizontal / vertical directions. Has been.

以下に、本発明の第一実施例の洗濯機用防水パン１の施工方法を、図面を参照しつつ説明する。尚、特に詳述しないが、以下の施工の際には、必要に応じ接続箇所はパッキングや接着剤を利用して水密的に接続されてなる。
まず、洗濯機用防水パン１の取付口４ｂ周縁の鍔部４ａの上面に、接続部材８の筒部分を挿通し、接続部材８のフランジ部８ａ下面と取付口４ｂ周縁の鍔部４ａ上面とが当接するように配置する。
次に、継手部材９を洗濯機用防水パン１の下方から取付口４ｂ周縁に配置し、接続部材８の雄ネジを継手部材９の雌ネジに螺合させて、フランジ部８ａ下面と継手部材９上面とで鍔部４ａを挟持させ、接続部材８及び継手部材９を洗濯機用防水パン１に接続固定する。この接続部材８及び継手部材９を接続筒部４上端に接続固定したことによって、接続筒部４上端に配管接続部５が形成される。前述の通り、接続筒部４は底壁部２より上方に延出されているため、配管接続部５は底壁部２よりも高い位置に設けられてなる。
次に、配管接続部５の接続部８ｂに、逆流防止弁部材１０の弁部材挿入部１０ｂを挿入し嵌合接続する。尚、当然ながら、この接続に際して、逆流防止弁部材１０の排水口１０ｃは、洗濯機用防水パン１の側壁部３の上端よりも低い位置となるように設計されてなる。
次に、配管接続部５の受入部９ａ内面または床面の開口ＦＯから延出された縦配管ＦＰの上端外面のいずれか一方に接着剤を塗布した上で、受入部９ａ内に縦配管ＦＰの端部を挿入しつつ、洗濯機用防水パン１を床面Ｆ上に設置する。この作業は、設置の際に縦配管ＦＰの位置を横方向から視認しつつ行うことができるため、容易に行うことができる。
これにより、配管接続部５が、床下配管から床面Ｆ上に延出された縦配管ＦＰと、洗濯機用防水パン１の裏側の空間にて接続され、以降、縦配管ＦＰから下流側の配管はパン排水配管Ｐとなる。
尚、床面の開口ＦＯから延出している縦配管ＦＰの下端であって、床面の開口ＦＯと同じ高さ、または床面よりも上方の高さ位置には、図８に示したように、エルボ管の端部に設けたソケット部ＰＳが存在するが、図１より明らかなように、配管接続部５において縦配管ＦＰが挿入される受入部９ａは、洗濯機用防水パン１の底壁部２よりも充分高い接続筒部４の上端の位置にあり、上記縦配管ＦＰと受入部９ａとの接続に際し、受入部９ａとソケット部ＰＳは上下方向に充分な距離があるため、互いに干渉することは無い。
次に、ビスなどを利用し、洗濯機用防水パン１を床面Ｆ上の設置場所に固定する。
次に、洗濯機Ｓを床面Ｆ上の任意の場所に設置する。洗濯機Ｓの位置は、洗濯機用防水パン１の上方でも良いし、それ以外の床面Ｆ上でも良い。
更に洗濯機Ｓの洗濯機排水配管１１のエルボ部材１１ｂの端部を、洗濯機用防水パン１の逆流防止弁部材１０の弁部材接続部１０ａを接続させ、逆流防止弁部材１０を介して、洗濯機用防水パン１の配管接続部５と洗濯機排水配管１１を接続させて、本実施例の洗濯機用防水パン１の施工が完了する。 Below, the construction method of the waterproof pan 1 for washing machines of the first embodiment of the present invention will be described with reference to the drawings. Although not described in detail, in the following construction, the connection locations are connected in a watertight manner using packing or an adhesive as necessary.
First, the cylindrical portion of the connection member 8 is inserted into the upper surface of the flange 4a at the periphery of the attachment port 4b of the waterproof pan 1 for a washing machine, and the lower surface of the flange 8a of the connection member 8 and the upper surface of the flange 4a at the periphery of the attachment port 4b Are arranged so that they abut.
Next, the joint member 9 is disposed on the periphery of the attachment port 4b from the lower side of the waterproof pan 1 for a washing machine, and the male screw of the connection member 8 is screwed into the female screw of the joint member 9, so that the lower surface of the flange portion 8a and the joint member 9 The upper part 4a is clamped with the upper surface, and the connection member 8 and the joint member 9 are connected and fixed to the waterproof pan 1 for a washing machine. By connecting and fixing the connection member 8 and the joint member 9 to the upper end of the connection tube portion 4, the pipe connection portion 5 is formed at the upper end of the connection tube portion 4. As described above, since the connection cylinder portion 4 extends upward from the bottom wall portion 2, the pipe connection portion 5 is provided at a position higher than the bottom wall portion 2.
Next, the valve member insertion portion 10b of the backflow prevention valve member 10 is inserted into the connection portion 8b of the pipe connection portion 5 and connected. Of course, the drain port 10c of the backflow prevention valve member 10 is designed to be lower than the upper end of the side wall portion 3 of the waterproof pan 1 for a washing machine.
Next, after applying an adhesive to one of the inner surface of the receiving portion 9a of the pipe connecting portion 5 and the outer surface of the upper end of the vertical piping FP extending from the opening FO on the floor surface, the vertical piping FP is placed in the receiving portion 9a. The waterproof pan 1 for a washing machine is placed on the floor surface F while inserting the end of. This operation can be easily performed because the position of the vertical pipe FP can be viewed from the lateral direction during installation.
Thereby, the pipe connection part 5 is connected in the space behind the vertical pipe FP extended on the floor surface F from the underfloor pipe and the waterproof pan 1 for the washing machine, and thereafter the downstream side from the vertical pipe FP. The piping becomes a pan drainage piping P.
As shown in FIG. 8, the lower end of the vertical pipe FP extending from the opening FO on the floor surface is at the same height as the opening FO on the floor surface or a height position above the floor surface. In addition, the socket part PS provided at the end of the elbow pipe exists, but as is apparent from FIG. 1, the receiving part 9a into which the vertical pipe FP is inserted in the pipe connection part 5 is the waterproof pan 1 for the washing machine. At the position of the upper end of the connecting cylinder part 4 that is sufficiently higher than the bottom wall part 2, and when the vertical pipe FP and the receiving part 9a are connected, the receiving part 9a and the socket part PS have a sufficient distance in the vertical direction. They do not interfere with each other.
Next, the waterproof pan 1 for a washing machine is fixed to an installation location on the floor surface F using a screw or the like.
Next, the washing machine S is installed at an arbitrary location on the floor surface F. The position of the washing machine S may be above the waterproof pan 1 for the washing machine, or may be on the other floor surface F.
Furthermore, the end part of the elbow member 11b of the washing machine drain pipe 11 of the washing machine S is connected to the valve member connection part 10a of the backflow prevention valve member 10 of the waterproof pan 1 for the washing machine, and the backflow prevention valve member 10 is connected. The piping connection part 5 of the waterproof pan 1 for washing machines and the washing machine drain pipe 11 are connected, and the construction of the waterproof pan 1 for washing machines of this embodiment is completed.

洗濯機Ｓの使用により洗濯機排水配管１１から排水が行われた場合、排水は洗濯機排水配管１１から、逆流防止弁部材１０、配管接続部５、の順に通過し、パン排水配管Ｐである縦配管ＦＰから床下配管を介して下水側に排出される。尚、逆流防止弁部材１０内を排水が通過する際には、逆流防止弁１０ｄが作用するため、洗濯機用防水パン１内に排水が逆流することは無い。
また、配管の接続箇所等から若干の漏水が洗濯機用防水パン１内に発生した場合には、漏水は洗濯機用防水パン１内に留まり、他の床面Ｆ上に流出することは無いため、床面Ｆ上が汚損されることを防止できる。
また、洗濯機排水配管１１が故障したなどの理由で洗濯機用防水パン１内に大量の排水が発生した場合、溜まった排水の水位が接続筒部４上端の排水口１０ｃに達した時点で、逆流防止弁１０ｄが開口し、洗濯機用防水パン１内の排水は、排水口１０ｃから縦配管ＦＰ及び床下配管を介して下水側に排出される。 When the washing machine S is drained from the washing machine drain pipe 11, the drainage passes through the washing machine drain pipe 11 in the order of the backflow prevention valve member 10 and the pipe connection portion 5, and is the pan drain pipe P. It is discharged from the vertical pipe FP to the sewage side through the underfloor pipe. In addition, when the wastewater passes through the backflow prevention valve member 10, the backflow prevention valve 10d acts, so that the wastewater does not flow back into the washing machine waterproof pan 1.
Further, when a slight water leak occurs in the waterproof pan 1 for a washing machine from a connecting point of the piping, the water leak stays in the waterproof pan 1 for a washing machine and does not flow out on the other floor surface F. Therefore, it is possible to prevent the floor surface F from being soiled.
Further, when a large amount of drainage is generated in the waterproof pan 1 for the washing machine due to a failure of the washing machine drainage pipe 11 or the like, when the accumulated drainage water level reaches the drainage port 10c at the upper end of the connecting tube portion 4. The backflow prevention valve 10d is opened, and the waste water in the waterproof pan 1 for the washing machine is discharged from the drain port 10c to the sewage side through the vertical pipe FP and the underfloor pipe.

Next, the pan drain pipe P is bent vertically upward along the outer wall surface of the bathroom, is bent horizontally at the height position of the through hole BH on the bathroom wall surface, and the pipe is passed through the through hole BH. In the bathroom, the pipe is bent vertically downward along the inner wall surface of the bathroom. Finally, the end of the pan drainage pipe P is placed in the bathroom and on the bathroom washroom. Moreover, the edge part inside the bathroom of the bread | pan drainage piping P is extended to the height position from which the lower end becomes lower than the upper end of the connection member 8 of the waterproofing bread 1 for washing machines.
Next, the waterproof pan 1 for a washing machine is fixed to an installation location on the floor surface F using a screw or the like.
Next, the washing machine S is installed at an arbitrary location on the floor surface F. The position of the washing machine S may be above the waterproof pan 1 for the washing machine, or may be on the other floor surface F.
Further, the end of the elbow member 11b of the washing machine drain pipe 11 of the washing machine S is connected to the connection part 8b, and the pipe connection part 5 of the waterproof pan 1 for washing machine and the washing machine drain pipe 11 are connected to each other. The construction of the waterproof pan 1 for a washing machine of the embodiment is completed. As described in paragraph 0014, the inner surface of the connection member 8, the joint member 9, the elbow member 11b, and the vertical pipe portion FP is connected without a step when the construction is completed.

洗濯機Ｓの使用により洗濯機排水配管１１から排水が行われた場合、排水は洗濯機排水配管１１から、配管接続部５、パン排水配管Ｐの順に通過し、浴室の洗い場内に排出され、浴室の洗い場排水口を介して下水側に排出される。
パン排水配管Ｐの、貫通孔ＢＨ部分の配管の高さ位置は、床面Ｆ上に配置した配管よりも高い位置に配置されているが、洗濯機Ｓを使用し排水が大量に流れた際には、一時的に洗濯機Ｓの内部であって、貫通孔ＢＨよりも高い位置から排水が生じ、貫通孔ＢＨの高さ位置の配管を超えて浴室内に排水が行われる。また、この時には、パン排水配管Ｐが排水のみで満たされた満管状態となり、サイホン効果が発生する。このサイホン効果は、接続部材８と継手部材９、エルボ部材１１ｂ、及び縦管部ＦＰにおいて、その内面が段差なく接続されていることで排水の流れがスムーズとなり、また空気だまりも発生しないため、特に発生し易くなっている。
パン排水配管Ｐの、浴室内の端部は、接続部材８の上端よりも下方となる高さ位置のため、サイホン効果により、パン排水配管Ｐ内が満管状態を維持する限り、排水は貫通孔ＢＨの高さ位置を超えて、支障なく浴室内に排出される。
また、配管などの接続部８ｂから若干の漏水が洗濯機用防水パン１内に発生した場合には、漏水は洗濯機用防水パン１内に留まり、他の床面Ｆ上に流出することは無いため、床面Ｆ上が汚損されることを防止できる。 When drainage is performed from the washing machine drainage pipe 11 by using the washing machine S, the drainage passes through the washing machine drainage pipe 11 in the order of the pipe connection portion 5 and the pan drainage pipe P, and is discharged into the bathroom washroom. It is discharged to the sewage through the bathroom washroom drain.
The height of the pipe in the through-hole BH portion of the pan drainage pipe P is arranged higher than the pipe arranged on the floor surface F, but when a large amount of drainage flows using the washing machine S In the washing machine S, drainage is temporarily generated from a position higher than the through hole BH, and drained into the bathroom beyond the pipe at the height position of the through hole BH. At this time, the pan drainage pipe P is filled with only drainage, and a siphon effect is generated. This siphon effect is because the flow of drainage is smooth because the inner surface of the connecting member 8, the joint member 9, the elbow member 11b, and the vertical pipe portion FP is connected without any step, and no air accumulation occurs. This is particularly likely to occur.
Since the end of the pan drainage pipe P in the bathroom is at a height lower than the upper end of the connecting member 8, drainage passes through the siphon effect as long as the inside of the pan drainage pipe P remains full. Beyond the height position of the hole BH, it is discharged into the bathroom without hindrance.
In addition, when some water leakage occurs in the waterproofing pan 1 for the washing machine from the connecting portion 8b such as a pipe, the leakage remains in the waterproofing pan 1 for the washing machine and does not flow out onto the other floor surface F. Therefore, the floor surface F can be prevented from being soiled.

上記第二実施例では、床下配管を行う第一実施例と同じ洗濯機用防水パン１を使用しつつ、床上配管に対応することができる。床下配管用の洗濯機用防水パン１と床上配管用の洗濯機用防水パン１とを、同じ洗濯機用防水パン１で兼用できるため、床上配管に対応した洗濯機用防水パン１を、床下配管に対応した洗濯機用防水パン１と同じ程度の安価な価格で提供できる。 In the said 2nd Example, it can respond to floor piping, using the waterproofing pan 1 for washing machines same as 1st Example which performs underfloor piping. Since the waterproof pan 1 for a washing machine for underfloor piping and the waterproof pan 1 for a washing machine for floor piping can be shared by the same waterproof pan 1 for a washing machine, the waterproof pan 1 for a washing machine corresponding to the floor piping is It can be provided at the same low price as the waterproof pan 1 for a washing machine corresponding to piping.

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、要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、上記実施例では、洗濯機用防水パン１は平面視略長方形形状に構成されてなるが、本発明は上記実施例に限定されるものでは無く、平面視略正方形形状など、必要に応じて円形や略多角形形状に構成しても良い。
また略長方形形状の場合、上記実施例のように、短辺にのみ配管カバー部６を延出し、対応する切出溝７ａを設けるのではなく、長辺のみ、または短辺と長辺の両方にそれぞれ配管カバー部６を延出し、それに対応する切溝部を設けるようにしてもよい。
また、上記実施例では、外壁部３ｂに切出溝７ａを設け、この切出溝７ａに沿って外壁部３ｂを切断することで、床下配管と床上配管の両方に対応する構造としているが、本発明は上記実施例に限定することなく、入れ子式と呼ばれる金型を採用することで、一組の金型で床下配管と床上配管の両方に対応した洗濯機用防水パン１を製造することができる。
入れ子式金型とは、金型の一部分だけを交換可能とした金型であり、本発明の場合、上記切欠部７ｂの周辺部分について、切欠部７ｂのある金型と切欠部７ｂの無い金型の２種類を用意し、必要に応じて交換することで、一組の金型で、切欠部７ｂのある床上配管用の洗濯機用防水パン１と、切欠部７ｂの無い床下配管用の洗濯機用防水パン１をそれぞれ生産することができる。入れ子式金型とすることによる金型代のコストアップはわずかであるから、この入れ子式金型の場合でも、床上配管に対応した洗濯機用防水パン１を、床下配管に対応した洗濯機用防水パン１と同じ程度の安価な価格で提供できる。
また、上記第一実施例においてはパン排水配管Ｐは単なる排水の流路のみ形成してなるが、必要に応じ、下流側からの臭気や害虫類の屋内側への侵入を防止する排水トラップを流路上に設けて、臭気や害虫類の屋内側への侵入を防止するようにしてもよい。 The embodiments of the present invention are as described above.
