Description

本発明は、水槽内に水平方向もしくは水平方向から傾斜した方向に回転自在に支持された回転ドラム内で洗濯、すすぎ、脱水、乾燥の各行程を行うドラム式洗濯乾燥機に関するものである。   The present invention relates to a drum type washing and drying machine that performs washing, rinsing, dewatering, and drying processes in a rotating drum that is rotatably supported in a water tank in a horizontal direction or in a direction inclined from the horizontal direction.

従来この種のドラム式洗濯乾燥機は、乾燥風を循環供給する循環風路を利用して捕獲したリント(糸くず)を、水洗いによる自動的に除去する方式が提案されている(例えば、特許文献1参照)。   Conventionally, a drum-type washing and drying machine of this type has been proposed that automatically removes lint captured by using a circulation air passage that circulates and supplies drying air by washing with water (for example, a patent) Reference 1).

図3は、特許文献1に記載された従来のドラム式洗濯乾燥機の全体構成縦断面図を示すものである。図3に示すように、多数の透孔4aが形成され洗濯物を収容して回転駆動される回転ドラム4が水槽3内に回転自在に設けられ、水槽3内への給水、排水及び回転ドラム4の回転の制御等により洗濯、すすぎ、脱水の各行程を実施する。   FIG. 3 is a longitudinal sectional view of the entire configuration of a conventional drum-type washing and drying machine described in Patent Document 1. As shown in FIG. As shown in FIG. 3, a rotating drum 4 that is formed with a large number of through holes 4a and is rotationally driven to accommodate laundry is rotatably provided in the water tank 3, and water supply, drainage, and rotating drums into the water tank 3 are provided. 4. Washing, rinsing and dehydrating processes are performed by controlling the rotation of No. 4.

乾燥行程は、水槽3の背面に設けた排気ダクト15に接続配管した循環風路13、蒸発器20、凝縮器19を備えた熱交換ダクト16、送風手段である送風ファン21、水槽3の前面に接続した給気ダクト14、により水槽3内の空気を循環させることにより洗濯物の乾燥を実施するようになっている。   The drying process includes a circulation air passage 13 connected to an exhaust duct 15 provided on the back surface of the water tank 3, a heat exchange duct 16 provided with an evaporator 20 and a condenser 19, a blower fan 21 as a blowing means, and a front surface of the water tank 3. The laundry is dried by circulating the air in the water tub 3 by the air supply duct 14 connected to the air.

熱交換ダクト16と循環風路13との接続部、送風ファン21と給気ダクト14との接続部は、固定されている風路側と揺動する水槽3側との接続であり、ゴム等の柔軟性のある材質で断面蛇腹状の接続体17b、17aにて振動を吸収しつつ接続している。   The connection part between the heat exchange duct 16 and the circulation air passage 13 and the connection part between the blower fan 21 and the air supply duct 14 are the connection between the fixed air passage side and the oscillating water tank 3 side. The connecting members 17b and 17a made of a flexible material and having a bellows cross section are connected while absorbing vibration.

衣類等に付着したり、剥離した糸屑等のリントを除去する為に、熱交換ダクト16の上流側に通路を遮断するようにリントフィルター22を装備してリントを捕獲する。   In order to remove lint such as lint that has adhered to clothes or peeled off, a lint filter 22 is installed on the upstream side of the heat exchange duct 16 to intercept the lint.

さらに、リントフィルター22の上流側の縦面に沿って注水可能とした注水ノズル23を備え、給水弁ユニット25からの給水により捕獲したリントを清掃する為に洗い流す水洗い手段を設け、熱交換ダクト16の最低部位に水抜き口27設け、この水抜き口27よりダクト配水管、排水弁29を介して、主配水管12よりリントの除去が出来るようになっている。   Furthermore, a water injection nozzle 23 capable of water injection along the vertical surface on the upstream side of the lint filter 22 is provided, and a water washing means for washing out the lint captured by the water supply from the water supply valve unit 25 is provided, and the heat exchange duct 16 is provided. The drainage port 27 is provided at the lowest part of the pipe, and the lint can be removed from the main water distribution pipe 12 through the water drainage port 27 and the duct water distribution pipe and the drain valve 29.

これは、リントが多量に詰まると、循環風量が減少し乾燥効率が低下するので、循環風からリントを除去しなければならないためである。   This is because if the lint is clogged in a large amount, the circulating air volume decreases and the drying efficiency decreases, so the lint must be removed from the circulating air.

一方、水槽3底部の後方最下部には、排水口8が形成され途中に排水弁9を備えた槽排水管10が連通接続され、その先端側にフィルタ装置11を構成し、洗濯行程やすすぎ行程での排水中からリントを捕獲除去する。   On the other hand, at the bottom of the rear of the bottom of the water tub 3, a drain port 8 is formed and a tank drain pipe 10 provided with a drain valve 9 is connected in the middle. Captures and removes lint from wastewater during the process.

しかしながら、前記従来の構成では、熱交換ダクト16に備えるフィルタ22にリントを捕獲する以前に、リントが循環風路13の壁面や段差にのりあげたり、壁面の水分や静電気によって異物であるリントが循環風路13の壁面に付着することが多々あり、特にゴム等の材質の接続体17b部分には摩擦係数も高い為付着しやすく、付着したリントが成長することで循環風路13をふさぎ、水槽3への循環送風の風量を減らし、風量の減少によって乾燥効率が落ち、乾燥時間が長くなる、あるいは乾燥ムラが多くなるという課題を有していた。   However, in the above-described conventional configuration, before the lint is captured by the filter 22 provided in the heat exchange duct 16, the lint rises on the wall surface or the step of the circulation air passage 13, or the lint that is a foreign matter due to moisture or static electricity on the wall surface It often adheres to the wall surface of the circulation air passage 13, and especially the connecting member 17b made of rubber or the like has a high friction coefficient so that it adheres easily. There was a problem that the air volume of the circulating air flow to the water tank 3 was reduced, the drying efficiency was lowered due to the reduction of the air volume, the drying time was prolonged, or the drying unevenness was increased.

本発明は、前記従来の課題を解決するもので、循環送風経路を洗浄することで、リントを除去し、乾燥効率が下がらないドラム式洗濯乾燥機を提供することにある。   This invention solves the said conventional subject, and is providing the drum type washing-drying machine which removes lint by wash | cleaning a circulation ventilation path | route, and a drying efficiency does not fall.

上記従来の課題を解決するために、本発明のドラム式洗濯乾燥機は、水槽内に設けられ洗濯物を収容して回転駆動される回転ドラムと、前記水槽内への給水、排水及び前記回転ドラムの回転の制御により洗濯、すすぎ、脱水、乾燥の各行程を制御する制御手段と、洗濯、すすぎ時に循環ポンプにて水を循環させる循環送水経路と、乾燥時に前記水槽内の空気を循環させる送風手段を有する循環送風経路と、前記循環送風経路の途中で異物を捕集するフィルタと、前記循環送風経路を通じて前記水槽に供給された空気を前記水槽から吸い込む吸気口とを備え、前記循環送水経路は、循環水を回転ドラム内に吐出する回転ドラム側吐出口と、前記吸気口近傍の循環送風経路側吐出口とに分岐させるとともに、前記回転ドラム側吐出口と前記循環送風経路側吐出口のいずれか一方から循環水を吐出するための切替え弁を設けたものである。   In order to solve the above-described conventional problems, a drum-type washing and drying machine according to the present invention includes a rotating drum that is provided in a water tub and is driven to rotate by containing laundry, water supply to the water tub, drainage, and the rotation. Control means for controlling each process of washing, rinsing, dehydration and drying by controlling the rotation of the drum, a circulation water supply path for circulating water by a circulation pump at the time of washing and rinsing, and air in the water tank at the time of drying A circulating air passage having a blowing means, a filter for collecting foreign matter in the middle of the circulating air passage, and an intake port for sucking air supplied to the water tank through the circulation air passage, from the water tank. The path branches into a rotary drum side discharge port for discharging circulating water into the rotary drum and a circulation air flow path side discharge port in the vicinity of the intake port, and the rotary drum side discharge port and the circulation feed It is provided with a switching valve for discharging the circulation water from one path side discharge port.

これによって、循環送風経路の壁面に付着した糸くずなどの異物であるリントを循環ポンプによって供給された水によって洗い流すことができる。   As a result, lint, which is a foreign matter such as lint attached to the wall surface of the circulation air passage, can be washed away with water supplied by the circulation pump.

本発明のドラム式洗濯乾燥機は、循環送風経路への壁面に付着するリントの堆積を防止することにより、乾燥効率の低下を防ぐことが出来る。   The drum type washing / drying machine of the present invention can prevent the drying efficiency from deteriorating by preventing the accumulation of lint adhering to the wall surface to the circulating air blowing path.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(実施の形態1)
図1は、本発明の第1の実施形態に係るドラム式洗濯乾燥機の側断面図を示すものである。本実施の形態1のドラム式洗濯乾燥機は、洗い、すすぎ、脱水等の洗濯行程と、乾燥行程を行う機能を有している。
(Embodiment 1)
FIG. 1 is a side sectional view of a drum type washing / drying machine according to a first embodiment of the present invention. The drum-type washing / drying machine of the first embodiment has a washing process such as washing, rinsing and dehydration, and a function of performing a drying process.

図1において、洗濯機筐体50の内部に揺動自在に水槽51が配設され、水槽51内には、回転ドラム52が回転自在に軸支され、前記回転ドラム52は、水槽51の背面に外側より取り付けられたモータ53により回転駆動される。   In FIG. 1, a water tank 51 is swingably disposed inside a washing machine casing 50, and a rotating drum 52 is rotatably supported in the water tank 51. The rotating drum 52 is a back surface of the water tank 51. The motor 53 is rotatably driven from the outside.

洗濯機本体50の前面上部に設けられる操作パネル60から入力により、制御装置(制御手段)61が、洗濯、脱水、乾燥などの運転制御を行う。   A control device (control means) 61 performs operation control such as washing, dehydration, and drying in response to an input from an operation panel 60 provided on the upper front surface of the washing machine body 50.

洗濯やすすぎ運転時には、給水装置54の電磁弁(図示せず)の開放動作によって図示しない洗剤ケース、給水ホース55を介して実線矢印Aで示すように洗濯水を水槽51内に適時に投入する。   During washing and rinsing operation, washing water is poured into the water tank 51 in a timely manner as indicated by a solid arrow A through a detergent case (not shown) and a water supply hose 55 by opening an electromagnetic valve (not shown) of the water supply device 54. .

排水時には、水槽51底部に排水管56を配管し、排水管56より排水フィルタ57を通過する際、異物を除去して排水系58より排水弁59の開放動作にて機外に洗濯水を排出する。排水フィルタ57に捕捉したリント等の異物は、使用者が適宜清掃する事で除去される。   When draining, a drain pipe 56 is installed at the bottom of the water tank 51, and when passing through the drain filter 57 from the drain pipe 56, foreign matter is removed and the washing water is discharged from the drain system 58 by opening the drain valve 59. To do. Foreign matters such as lint captured by the drainage filter 57 are removed by the user's appropriate cleaning.

また、洗濯やすすぎ運転中に洗剤の溶解を高めたり、すすぎ水の衣類の透過を向上させる等の洗いやすすぎの機能向上を図るため、循環送水経路66にて水槽51内の水を循環させる機能を有している。   In addition, the water in the water tank 51 is circulated in the circulation water supply path 66 in order to improve the function of washing and rinsing, such as increasing the dissolution of the detergent during washing and rinsing operations, and improving the permeation of clothes of rinsing water. It has a function.

即ち、洗濯やすすぎ運転時には、水槽51内部の洗濯水は、循環ポンプ67を駆動させることで、排水管56(水循環系の一部を構成)を経由し、フィルタ57から流入配管68につながる循環ポンプ67を経由して、吐出配管69より切替え弁70および回転ドラム側吐出配管71から、回転ドラム側吐出口72より矢印Cで示すように回転ドラム52の前面開口側から内方に注水して戻すことを繰り返すことにより循環水流を形成する。   That is, during washing and rinsing operation, the washing water in the water tank 51 is circulated from the filter 57 to the inflow pipe 68 through the drain pipe 56 (which constitutes a part of the water circulation system) by driving the circulation pump 67. Water is injected inward from the front opening side of the rotary drum 52 from the switching valve 70 and the rotary drum side discharge pipe 71 through the pump 67 and from the rotary drum side discharge port 72 as indicated by an arrow C. A circulating water stream is formed by repeating the return.

一方、乾燥運転時には、水槽51および回転ドラム52内の空気を、水槽51上部の吸気口65より送風機62によって吸引(矢印B“)し、破線で示すように乾燥系63に送風し(矢印B)、乾燥系63内方の除湿部(図示せず)および加熱部(図示せず)にて乾燥加熱した空気を給気口64より水槽51内部に戻す(矢印B‘)という循環送風を繰り返して回転ドラム52内部の衣類を乾燥する。   On the other hand, during the drying operation, the air in the water tank 51 and the rotary drum 52 is sucked by the blower 62 from the air inlet 65 above the water tank 51 (arrow B ") and blown to the drying system 63 as indicated by the broken line (arrow B). ), And circulating air that repeatedly returns the air dried and heated by the dehumidifying part (not shown) and the heating part (not shown) inside the drying system 63 to the inside of the water tank 51 (arrow B ′) through the air supply port 64 is repeated. The clothes in the rotary drum 52 are dried.

なお、吸気口65から送風機62に至る循環送風経路74途中には、フィルタ73を外部から取外し可能に配し、衣類から発生した異物やリントを捕獲した後、乾燥系63に送風することにより、乾燥効率の低下を防止する。フィルタ73に堆積したリント等の異物は、使用者が適当な時期に取り外して清掃等で排除する作業を繰り返す。   In the middle of the circulation air flow path 74 from the air inlet 65 to the blower 62, the filter 73 is arranged so as to be removable from the outside, and after capturing foreign matter and lint generated from clothing, the air is sent to the drying system 63, Prevents drying efficiency from decreasing. Foreign matter such as lint accumulated on the filter 73 is removed by the user at an appropriate time and removed by cleaning or the like.

また、回転ドラム52の回転により揺動する水槽51と、洗濯機本体50に構成した固定側部材である循環送風経路74との接続部には、屈曲性を有するゴム材質等で構成した蛇腹状の屈曲接続部75で接続配管する。   In addition, the connection portion between the water tank 51 that swings due to the rotation of the rotating drum 52 and the circulation air passage 74 that is a fixed-side member configured in the washing machine body 50 has a bellows shape that is formed of a flexible rubber material or the like. The connecting pipe is connected at the bent connecting portion 75.

なお、循環送水経路66に構成した切替え弁70は、洗濯やすすぎ行程時、既述したように回転ドラム側吐出配管71側に洗濯水が流れるように切替えているが、乾燥行程時には、切替え弁70を循環送風経路側排出配管76に切り替える。   Note that the switching valve 70 configured in the circulating water supply path 66 is switched so that the washing water flows to the rotary drum side discharge pipe 71 side during the washing and rinsing process, as described above, but during the drying process, the switching valve 70 is switched. 70 is switched to the circulation ventilation path side discharge piping 76.

循環送風経路側排出配管76上方の循環送風経路側吐出口77からは、矢印Dに示すように循環送風経路74の吸気口65および屈曲接続部75の内径部に向けて循環水流が吐出するように構成されている。   As shown by an arrow D, the circulating water flow is discharged from the circulation fan path side discharge port 77 above the circulation fan path discharge pipe 76 toward the intake port 65 of the circulation fan path 74 and the inner diameter portion of the bent connection part 75. It is configured.

以上のように構成されたドラム式洗濯乾燥機について以下その動作、作用を説明する。   The operation and action of the drum type washing and drying machine configured as described above will be described below.

乾燥行程時、水槽51内部の湿った空気を送風機62により吸気口65から循環送風経路74に吸引する動作を行うとともに、循環ポンプ67で駆動している循環送水経路66の循環水流を、切替え弁70にて循環送風経路側排出配管76に切り替える。これにより吸気口65および屈曲接続部75に付着、堆積している糸屑などのリントを循環送風経路側吐出口77からの注水にて洗い流し、堆積することを防止する。   During the drying process, the air inside the water tank 51 is sucked from the intake port 65 to the circulation air flow path 74 by the blower 62, and the circulation water flow in the circulation water supply path 66 driven by the circulation pump 67 is changed over to the switching valve. At 70, switching to the circulation air passage side discharge pipe 76 is performed. As a result, lint such as lint that adheres to and accumulates on the intake port 65 and the bent connection portion 75 is washed away by water injection from the discharge port 77 on the circulation air passage side and is prevented from accumulating.

このとき、乾燥行程時に給水装置54より給水を行うこととなるが、給水量は洗濯時やすすぎ時よりも少量であり、図示しない水位検知手段により水槽51の底部であって回転ドラム52内に水が達しない程度の水位となるように給水を行うこととする。   At this time, water is supplied from the water supply device 54 during the drying process, but the amount of water supply is smaller than that during washing and too much, and the water level detection means (not shown) is located at the bottom of the water tank 51 and in the rotating drum 52. Water supply will be performed so that the water level will not reach.

なお、循環送風経路側吐出口77や屈曲接続部75内部から洗い流された糸屑等のリントは、水槽51底部の排水管56より排水フィルタ57を通過する際、異物を除去されるので、衣類に再付着することを防止できる。   Note that lint such as lint washed away from the inside of the circulation air passage route side discharge port 77 and the bent connection portion 75 is removed from foreign matter when passing through the drainage filter 57 from the drainage pipe 56 at the bottom of the water tank 51. Can be prevented from re-adhering.

以上のように、本実施の形態においては、吸気口65や屈曲接続部75部分に付着したり静電気や壁面の水分で付着するリント等の異物が堆積して管路を塞いで循環送風量が減少し乾燥効率を低下させ、乾燥時間が長くなるという不具合を防止できる。   As described above, in the present embodiment, foreign matter such as lint that adheres to the intake port 65 and the bent connection portion 75, or adheres due to static electricity or moisture on the wall surface accumulates to block the pipe, and the circulating air flow rate is increased. This reduces the drying efficiency and prevents the problem that the drying time becomes longer.

(実施の形態2)
図2は、本発明の第2の実施形態に係るドラム式洗濯乾燥機の側断面図を示すものである。
(Embodiment 2)
FIG. 2 is a side sectional view of a drum type washing / drying machine according to a second embodiment of the present invention.

図2において、循環送風経路側排出配管76は、上方に延設部80を構成し、循環送風経路74と接続口81にて屈曲接続部75の上方で接続する。   In FIG. 2, the circulation ventilation path side discharge pipe 76 constitutes an extending portion 80 upward, and is connected to the circulation ventilation path 74 and the connection port 81 above the bent connection portion 75.

従って、乾燥行程時に循環送風経路側排出配管76を流れる循環水は、屈曲接続部75の上方から矢印Eのように屈曲接続部75の内部を下方に流れる構成である。その他の構成は実施の形態1と同様である。   Therefore, the circulating water flowing through the circulation air passage path side discharge pipe 76 during the drying process flows downward from the bent connection portion 75 as indicated by an arrow E from the upper side of the bent connection portion 75. Other configurations are the same as those of the first embodiment.

以上のように構成された本実施の形態によれば、ゴム材質等で構成した蛇腹状の屈曲接続部75は摩擦係数が高くリント等が付着し、溜まりやすいが、上方より注水されることにより、付着したリントが洗い流されるものである。   According to the present embodiment configured as described above, the bellows-like bent connection portion 75 made of a rubber material or the like has a high coefficient of friction, and lint or the like adheres easily. The attached lint is washed away.

また、従来のドラム式洗濯機の洗濯やすすぎ時の機能向上するために多用される循環ポンプを使用することで、乾燥行程での循環送風経路のリント堆積を防止するので、水を供給するために新たに循環ポンプを増やす等のコスト上昇を招くこと無く乾燥効率の低下を防止できる。   In addition, by using a circulation pump that is frequently used to improve the functions of conventional drum-type washing machines when washing and rinsing, it prevents lint accumulation in the circulation air passage during the drying process, so that water is supplied. Further, it is possible to prevent a decrease in drying efficiency without incurring a cost increase such as newly increasing a circulation pump.

以上のように、本発明にかかるドラム式洗濯乾燥機は、循環送風経路への壁面に付着するリントの堆積を防止することにより、乾燥効率の低下を防ぐことが出来るので、洗濯乾燥機の分野で有用である。   As described above, the drum-type washing and drying machine according to the present invention can prevent a decrease in drying efficiency by preventing lint from adhering to the wall surface to the circulation air flow path. It is useful in.
