Description

本発明は、洗濯乾燥機に係り、特に水冷式除湿風路を備えた洗濯乾燥機に関するものである。   The present invention relates to a washing / drying machine, and more particularly to a washing / drying machine having a water-cooled dehumidifying air passage.

洗い、脱水および乾燥行程を備えた洗濯乾燥機には、乾燥行程で洗濯兼脱水槽内の洗濯物を乾燥させるため、例えば送風機によって洗濯兼脱水槽内から吸い込んだ湿気を含んだ空気を除湿する手段として、水冷式除湿用熱交換器と、除湿後の空気を加熱して洗濯兼脱水槽内に吹き込むヒーターなどの加熱手段とを備えるものがある。   For a washing and drying machine equipped with a washing, dehydrating and drying process, in order to dry the laundry in the washing and dehydrating tank in the drying process, for example, the air containing moisture sucked from the washing and dehydrating tank is dehumidified by a blower As a means, there is one provided with a water-cooled dehumidifying heat exchanger and a heating means such as a heater for heating the dehumidified air and blowing it into the washing and dewatering tub.

水冷式除湿用熱交換器は、例えば、洗濯兼脱水槽内から吸い込んだ湿潤空気を除湿する除湿ダクト内に、冷却水を供給し、除湿ダクト内を流れる空気の流勢によって冷却水の水滴を跳ね上げて、空気と冷却水の接触による熱交換（冷却除湿）効率を高めるように構成されている。   The water-cooled dehumidification heat exchanger supplies cooling water to a dehumidifying duct that dehumidifies the humid air sucked from the washing and dewatering tub, for example, and drops water of cooling water by the flow of air flowing in the dehumidifying duct. It is configured to increase the heat exchange (cooling and dehumidification) efficiency by splashing up and contacting air and cooling water.

水冷式除湿用熱交換器を用いたものとして、空気を循環させる風路の一部に、熱交換板を風路と平行に配置し、この板面上に冷却水をジグザグ状に流して流下面積を拡大させ、熱交換効率をアップさせるための案内部材を設けたものがある（例えば、特許文献１参照）。   Assuming that a water-cooled dehumidification heat exchanger is used, a heat exchange plate is placed in parallel with the air passage in a part of the air passage that circulates air, and cooling water flows in a zigzag manner on the plate surface. There is one provided with a guide member for enlarging the area and increasing the heat exchange efficiency (for example, see Patent Document 1).

特許第３７１０７２５号公報（図１など）Japanese Patent No. 3710725 (FIG. 1 etc.)

洗濯乾燥機の内装密度を高める観点からすれば、上記のような除湿風路は、洗濯兼脱水槽に隣接配置し、その風路長はなるべく短い方が好ましい。しかしながら、除湿風路を洗濯兼脱水槽に隣接して、その風路長さを短くすると、除湿風路から流れ出た冷却水や除湿水が、洗濯兼脱水槽の脱水槽孔からその内部に入り込んで、乾燥衣類を濡らしてしまうという問題があった。特に、水槽が傾斜しているものにあってはその可能性が高くなる。   From the viewpoint of increasing the interior density of the washing / drying machine, it is preferable that the dehumidifying air passage as described above is disposed adjacent to the washing and dewatering tub and the air passage length is as short as possible. However, if the dehumidifying air passage is adjacent to the washing and dewatering tank and the length of the air passage is shortened, the cooling water and the dehumidifying water flowing out from the dehumidifying air passage will enter the inside of the washing and dewatering tank through the dewatering tank hole. There was a problem that wet dry clothes. In particular, if the water tank is inclined, the possibility is high.

本発明は上記課題に対応するものであり、水冷式除湿風路を洗濯兼脱水槽に隣接配置し、その風路長を従来より短くした洗濯乾燥機において、除湿風路から流れ出た冷却水や除湿水が、洗濯兼脱水槽の脱水槽孔から内部に入り込まないようにした洗濯乾燥機を提供するものである。   The present invention responds to the above-mentioned problem, and in a washing / drying machine in which a water-cooled dehumidifying air passage is disposed adjacent to a washing and dewatering tub and the air passage length is shorter than that in the prior art, the cooling water flowing out from the dehumidifying air passage, It is an object of the present invention to provide a washing / drying machine in which dehumidified water does not enter the inside of the dehydration tank hole of the washing / dehydration tank.

本発明は、水槽と、前記水槽に内設され、脱水槽孔が側面に設けられると共に底面に脱水槽底板を有した洗濯兼脱水槽と、前記洗濯兼脱水槽に温風を供給する温風供給手段と、前記洗濯兼脱水槽内から前記脱水槽孔を通過して排出された温風を、前記水槽の側面に開口し、上端部が前記脱水槽底板及び前記洗濯兼脱水槽底部のパルセータの上端よりも上方に位置した給気口を介して前記水槽外へ放出する除湿風路と、を備えた洗濯乾燥機において、前記洗濯兼脱水槽の、前記給気口の上端部に対向する位置より上方の側面にのみ前記脱水槽孔を設けたものである。
The present invention includes a water tub, a washing / dehydrating tub provided in the water tub, having a dewatering tub hole provided on a side surface and having a dewatering basin bottom plate on a bottom surface, and hot air for supplying warm air to the washing / dehydrating tub Supply means, and warm air discharged from the washing / dehydrating tub through the dehydrating tub hole is opened in a side surface of the water tub, and the upper end is the dehydration tub bottom plate and the pulsator at the bottom of the washing / dehydrating tub And a dehumidifying air passage that discharges to the outside of the water tank through an air supply port positioned above the upper end of the washing / drying tank, facing the upper end of the air supply port of the washing and dewatering tank The dehydration tank hole is provided only on the side surface above the position.

本発明の洗濯乾燥機によれば、洗濯兼脱水槽の側面の、除湿風路の給気口に対応する位置から洗濯兼脱水槽の底面に対応する位置までの領域に、脱水槽孔が設けられていないため、除湿風路から流れ出た冷却水や除湿水は、洗濯兼脱水槽の内部に入り込むことができず、水槽底部の排水溝から排出される。
また、本発明の洗濯乾燥機によれば、除湿風路内に配した熱交換手段を構成する部材のの下端部を、洗濯兼脱水槽とは反対側の除湿風路の壁面に近接または接触させているため、除湿風路から流れ出た冷却水や除湿水は、洗濯兼脱水槽とは反対側の除湿風路の壁面に沿って流れ、洗濯兼脱水槽の内部に入り込むことなく水槽底部の排水溝から排出される。 According to the washing and drying machine of the present invention, the dehydration tank hole is provided in the region from the position corresponding to the air supply opening of the dehumidification air passage to the position corresponding to the bottom surface of the washing and dehydration tank on the side surface of the washing and dehydration tank. Therefore, the cooling water and the dehumidified water flowing out from the dehumidifying air passage cannot enter the inside of the washing and dewatering tank and are discharged from the drainage groove at the bottom of the water tank.
Further, according to the washing / drying machine of the present invention, the lower end portion of the member constituting the heat exchange means arranged in the dehumidifying air passage is close to or in contact with the wall surface of the dehumidifying air passage on the side opposite to the washing and dewatering tub. Therefore, the cooling water or dehumidified water that flows out from the dehumidifying air passage flows along the wall of the dehumidifying air passage on the opposite side of the washing / dehydrating tub, and does not enter the inside of the washing / dehydrating tub. It is discharged from the drain.

実施の形態１．
図１は本発明の実施の形態１に係る洗濯乾燥機の水槽が傾斜した状態の構成図、図２は図１に対応する洗濯乾燥機の除湿風路部分の構成図である。なお、図１および図２の左側が洗濯乾燥機の前側に対応し、図１および図２の右側が洗濯乾燥機の後側に対応している。
この洗濯乾燥機は、筐体（外箱）１の内部に、洗濯兼脱水槽３を内装した水槽２と、洗濯兼脱水槽３から出た空気を除湿してその除湿した空気を洗濯兼脱水槽３に戻す風路とを備えている。 Embodiment 1 FIG.
FIG. 1 is a configuration diagram of a state in which a water tank of a washing and drying machine according to Embodiment 1 of the present invention is inclined, and FIG. 2 is a configuration diagram of a dehumidifying air passage portion of the washing and drying machine corresponding to FIG. The left side of FIGS. 1 and 2 corresponds to the front side of the laundry dryer, and the right side of FIGS. 1 and 2 corresponds to the rear side of the laundry dryer.
This washing / drying machine has a housing (outer box) 1 with a water tub 2 having a washing / dehydrating tub 3 installed therein, and dehumidifying the air discharged from the washing / dehydrating tub 3 and washing the dehumidified air. And an air passage returning to the water tank 3.

水槽２は、複数の吊り棒４で支持され、吊り棒可動部４Ａによる吊り棒４の上げ下げにより、傾斜可能に構成されている。吊り棒４は、吊り板５および吊り座５Ａを介して筐体１に取り付けられており、水槽２はその吊り棒支持部２Ａにおいて吊り棒４と連結している。水槽２と吊り棒４の連結部には、防振部材６が配置されていて、水槽２に加わる振動の影響を抑制している。   The water tank 2 is supported by a plurality of suspension rods 4 and is configured to be tiltable by raising and lowering the suspension rods 4 by a suspension rod movable portion 4A. The suspension rod 4 is attached to the housing 1 via a suspension plate 5 and a suspension seat 5A, and the water tank 2 is connected to the suspension rod 4 at the suspension rod support portion 2A. An anti-vibration member 6 is disposed at the connecting portion between the water tank 2 and the suspension rod 4 to suppress the influence of vibration applied to the water tank 2.

洗濯兼脱水槽３は、その側面を構成している脱水槽側板３Ａと、その底面を構成している脱水槽底板３Ｄから構成されており、脱水槽側板３Ａには複数の脱水槽孔３Ｂが設けられている。脱水槽側板３Ａの上部周囲には流体バランサ１９が配置され、脱水槽底板３Ｄの上には洗濯時や乾燥時に左右に回転するパルセータ９が取り付けられている。   The washing and dewatering tub 3 is composed of a dewatering tub side plate 3A constituting the side surface and a dewatering tub bottom plate 3D constituting the bottom surface, and the dewatering tub side plate 3A has a plurality of dewatering tub holes 3B. Is provided. A fluid balancer 19 is disposed around the top of the dewatering tank side plate 3A, and a pulsator 9 that rotates to the left and right during washing and drying is mounted on the dewatering tank bottom plate 3D.

水槽２の下側にはモータ７が取り付けられており、このモータ７の動力が回転軸８を介して洗濯兼脱水槽３やパルセータ９に伝達され、それらの回転に利用される。
また、筐体１の上部には、洗濯物の出入口があり、その出入口は扉１０で開閉自在に構成されている。 A motor 7 is attached to the lower side of the water tub 2, and the power of the motor 7 is transmitted to the washing / dehydrating tub 3 and the pulsator 9 through the rotating shaft 8 and used for their rotation.
In addition, there is a laundry doorway at the top of the housing 1, and the doorway is configured to be openable and closable by a door 10.

洗濯物の乾燥に供される風路は、この例では、洗濯兼脱水槽３、除湿風路１１、乾燥フィルタ１３、ファン１４およびヒータ１５などから、循環風路として構成されている。
除湿風路１１は洗濯兼脱水槽３の外側に水槽２と一体に形成されており、除湿風路１１の内部には、水冷式除湿用熱交換器として作用する熱交換手段である熱交換板（除湿板）１２が配置されている。この例では、除湿風路１１は洗濯兼脱水槽３と一体成型によるコンパクトな構成とされており、図中では、洗濯兼脱水槽３に近い方（洗濯兼脱水槽側）の除湿風路１１の壁を内側壁２Ｃとして表し、洗濯兼脱水槽３から遠い方（洗濯兼脱水槽の反対側）の除湿風路１１の壁を外側壁２Ｂとして表している。 In this example, the air passage used for drying the laundry is configured as a circulation air passage from the washing and dewatering tank 3, the dehumidifying air passage 11, the drying filter 13, the fan 14, the heater 15, and the like.
The dehumidifying air passage 11 is formed integrally with the water tub 2 outside the washing and dewatering tub 3, and inside the dehumidifying air passage 11 is a heat exchange plate that is a heat exchange means acting as a water-cooled dehumidifying heat exchanger. (Dehumidifying plate) 12 is arranged. In this example, the dehumidifying air passage 11 has a compact structure integrally formed with the washing and dewatering tub 3, and in the figure, the dehumidifying air passage 11 closer to the washing and dewatering tub 3 (on the washing and dewatering tub side). The wall of the dehumidification air passage 11 far from the washing / dehydrating tub 3 (the opposite side of the washing / dehydrating tub) is shown as the outer wall 2B.

除湿風路１１の給気口は、水槽２の輸送時や保管時に重ね置き（スタッキング）ができるように、水槽２の高さ方向の途中に形成されている。これに対応して、熱交換板１２は、その下端が除湿風路１１の給気口よりも高い位置に来るように配置されている。これは、洗濯時などにおいて、水流により熱交換板１２が揺らされ、その圧力による破損を防止するためである。これらの結果として、除湿風路１１の給気口は、図１および図２に示すように、洗濯兼脱水槽３の脱水槽側板３Ａの下端よりも上方に対応した位置に配置された状態となっている。   The air supply opening of the dehumidifying air passage 11 is formed in the middle of the water tank 2 in the height direction so that it can be stacked (stacked) when the water tank 2 is transported or stored. Correspondingly, the heat exchange plate 12 is arranged such that the lower end thereof is positioned higher than the air supply port of the dehumidifying air passage 11. This is to prevent damage due to the pressure of the heat exchange plate 12 being shaken by the water flow during washing. As a result of these, as shown in FIGS. 1 and 2, the air supply port of the dehumidifying air passage 11 is disposed at a position corresponding to the upper side of the lower end of the dewatering tub side plate 3 </ b> A of the washing and dewatering tub 3. It has become.

筐体１の後側上面には給水口１７が設けられており、給水口１７から取り入れられた水は、分岐弁１８を介して、洗濯兼脱水槽３または除湿風路１１に導入される。
なお、図２の中で、符号１６は除湿風路１１を含む循環風路における洗濯兼脱水槽３の空気取入口を表し、符号３０は洗濯兼脱水槽３内の衣類を表している。 A water supply port 17 is provided on the rear upper surface of the housing 1, and water taken from the water supply port 17 is introduced into the washing / dehydrating tub 3 or the dehumidifying air passage 11 through the branch valve 18.
In FIG. 2, reference numeral 16 denotes an air intake port of the washing / dehydrating tub 3 in the circulation air passage including the dehumidifying air passage 11, and reference numeral 30 denotes clothes in the washing / dehydrating tub 3.

次に上記洗濯乾燥機の作用を説明する。この洗濯乾燥機は、洗い、すすぎ、脱水および乾燥を行うことが可能となっているものであり、その際、水槽２は行程に応じてその傾斜状態を決定できる。例えば、洗いやすすぎ行程では、洗濯物の量に応じて直立または傾斜に設定する。脱水行程ではその性質上、水槽２は直立状態とするのが好ましい。一方、乾燥行程では、洗濯物の攪拌を促進させて乾燥効率を上げるために、通常、図１、図２のように、水槽２を傾斜させた状態で行う。
なお、洗い、すすぎ、および脱水行程は、基本的に従来と同様の作用により行われるため、以下では乾燥行程についての作用を説明する。 Next, the operation of the washing / drying machine will be described. This washing / drying machine can perform washing, rinsing, dehydration, and drying. At that time, the water tank 2 can determine the inclined state according to the stroke. For example, in an easy-to-wash process, it is set upright or inclined according to the amount of laundry. In the dehydration process, the water tank 2 is preferably in an upright state due to its nature. On the other hand, in the drying process, in order to promote the stirring of the laundry and increase the drying efficiency, the drying process is usually performed with the water tank 2 inclined as shown in FIGS.
In addition, since washing | cleaning, a rinse, and a spin-drying | dehydration process are fundamentally performed by the effect | action similar to the past, below, the effect | action regarding a drying process is demonstrated.

乾燥行程では、送風ファン１４の作用によって、洗濯兼脱水槽３内の衣類３０から放出された水分を含んだ空気を水槽３の底部の開口から排出し、除湿風路１１の給気口から除湿風路１１内に取り込む。そして、除湿風路１１で除湿された空気を乾燥フィルタ１３でフィルタリングし、ヒータ１５で加熱した後、その加熱空気を空気取入口１６から洗濯兼脱水槽３内に導入して衣類の乾燥に供するという、空気の循環を行っている。
このとき、除湿風路１１内には、分岐弁１８の切替により上方から冷却水が流下され、熱交換板１２の面上に沿って流れる。これにより、除湿風路１１内で、上方に向かう湿潤空気と流下する冷却水の接触による熱交換（冷却除湿）が行われて、湿潤空気の除湿が進行する。 In the drying process, the air containing the moisture released from the clothes 30 in the washing and dewatering tub 3 is discharged from the opening at the bottom of the water tub 3 by the action of the blower fan 14, and dehumidified from the air supply port of the dehumidifying air passage 11. The air is taken into the air passage 11. Then, after the air dehumidified in the dehumidifying air passage 11 is filtered by the drying filter 13 and heated by the heater 15, the heated air is introduced into the washing and dewatering tub 3 from the air intake port 16 to be used for drying clothes. The air is circulated.
At this time, in the dehumidifying air passage 11, the cooling water flows down from above by switching the branch valve 18 and flows along the surface of the heat exchange plate 12. As a result, heat exchange (cooling dehumidification) is performed in the dehumidifying air passage 11 by contact with the moist air flowing upward and the cooling water flowing down, and dehumidification of the moist air proceeds.

しかしながら、図１および図２に示すように、除湿風路１１を洗濯兼脱水槽３に近接させ、その風路長さを短くしている場合、除湿風路１１から流れ出た冷却水や除湿水が、洗濯兼脱水槽３の脱水槽孔３Ｂから内部に入り込んで、洗濯兼脱水槽３内部の衣類３０を濡らしてしまうおそれがある。
そこで本実施の形態では、少なくとも、洗濯兼脱水槽３の脱水槽側板３Ａの、除湿風路１１の給気口に対応する位置から洗濯兼脱水槽３の底面（脱水槽底板３Ｄの上側面）に対応する位置までの領域３Ｃには、脱水槽孔３Ｂを設けないようにしている。この構成によれば、除湿風路１１から流れ出た冷却水や除湿水は、洗濯兼脱水槽３の内部に入り込むことができなくなり、水槽２の底部の排水溝から排出されるため、冷却水や除湿水による乾燥衣類の濡れを防止できる。 However, as shown in FIGS. 1 and 2, when the dehumidifying air passage 11 is brought close to the washing and dewatering tub 3 and the length of the air passage is shortened, the cooling water and the dehumidifying water flowing out from the dehumidifying air passage 11 are used. However, there is a possibility that the clothes 30 inside the washing / dehydrating tank 3 may get wet through the dehydrating tank hole 3B of the washing / dehydrating tank 3 and get wet.
Therefore, in the present embodiment, at least the bottom surface of the washing and dewatering tank 3 (the upper surface of the dewatering tank bottom plate 3D) from the position corresponding to the air supply port of the dehumidifying air passage 11 of the dewatering tank side plate 3A of the washing and dewatering tank 3. The dewatering tank hole 3B is not provided in the region 3C up to the position corresponding to. According to this configuration, the cooling water and the dehumidifying water flowing out from the dehumidifying air passage 11 cannot enter the inside of the washing and dewatering tub 3 and are discharged from the drainage groove at the bottom of the water tub 2. Prevents dry clothing from getting wet by dehumidified water.

上記の図１、図２では、水槽２を傾斜した状態で乾燥行程を行う場合を説明したが、水槽２を直立とした状態で乾燥行程を行う場合にも同様の構成となるようにする。図３は水槽が直立した状態の図２に対応する構成図である。図３に示すように、水槽２が直立した状態においても、洗濯兼脱水槽３の脱水槽側板３Ａの、除湿風路１１の給気口に対応する位置から洗濯兼脱水槽３の底面（脱水槽底板３Ｄの上側面）に対応する位置までの領域３Ｃには、脱水槽孔３Ｂを設けないようにしている。   In FIG. 1 and FIG. 2 described above, the case where the drying process is performed in a state where the water tank 2 is inclined has been described. However, the same configuration is also provided when the drying process is performed in a state where the water tank 2 is upright. FIG. 3 is a configuration diagram corresponding to FIG. 2 in a state where the water tank stands upright. As shown in FIG. 3, even when the water tub 2 is upright, the bottom surface of the washing and dewatering tub 3 is removed from the position corresponding to the air supply port of the dehumidifying air passage 11 of the dewatering tub side plate 3A of the washing and dewatering tub 3. The dewatering tank hole 3B is not provided in the region 3C up to the position corresponding to the upper surface of the water tank bottom plate 3D.

ここで、洗濯兼脱水槽３の脱水槽側板３Ａの、除湿風路１１の給気口に対応する位置とは、除湿風路１１の内側壁２Ｃの最下端を通る仮想水平線を引いた時に、その仮想水平線が脱水槽側板３Ａと交わる位置である。したがって、本実施の形態のように、水槽２が傾斜可能に構成されている場合には、水槽２が傾斜しているときと、水槽２が直立しているときでは、その位置が少し異なる。ただし、図１や図２のような水槽２の傾斜時を基準に、洗濯兼脱水槽３の脱水槽側板３Ａの、除湿風路１１の給気口に対応する位置を決定しておけば、洗濯兼脱水槽３が直立した状態もカバーできる構成となる。
一方、洗濯兼脱水槽３の脱水槽側板３Ａの、洗濯兼脱水槽３の底面（脱水槽底板３Ｄの上側面）に対応する位置とは、脱水槽底板３Ｄの上側面を通る仮想水平線を引いた時に、その仮想水平線が脱水槽側板３Ａと交わる位置である。 Here, the position of the dewatering tub side plate 3A of the washing and dewatering tub 3 corresponding to the air supply opening of the dehumidifying air passage 11 is drawn when a virtual horizontal line passing through the lowermost end of the inner wall 2C of the dehumidifying air passage 11 is drawn. The virtual horizontal line is a position where the dehydration tank side plate 3A intersects. Therefore, when the water tank 2 is configured to be tiltable as in the present embodiment, the position is slightly different when the water tank 2 is inclined and when the water tank 2 is upright. However, if the position corresponding to the air supply opening of the dehumidifying air passage 11 of the dewatering tank side plate 3A of the washing and dewatering tank 3 is determined based on the inclination of the water tank 2 as shown in FIG. 1 and FIG. The washing and dewatering tub 3 is configured to cover the upright state.
On the other hand, the position corresponding to the bottom surface of the washing and dewatering tank 3 (the upper surface of the dehydration tank bottom plate 3D) of the dewatering tank side plate 3A of the washing and dewatering tank 3 is drawn with a virtual horizontal line passing through the upper surface of the dewatering tank bottom plate 3D. The virtual horizontal line intersects the dehydration tank side plate 3A.

なお、図１〜図３において、脱水槽側板３Ａの、除湿風路１１の給気口に対応する位置から下側全域にわたって、脱水槽孔３Ｂを設けないようにすれば、除湿風路１１の給気口から流れ出た冷却水や除湿水が、洗濯兼脱水槽３内に入るのをより確実に防止できるのは言うまでもない。   In FIGS. 1 to 3, if the dehydration tank hole 3 </ b> B is not provided from the position corresponding to the air supply port of the dehumidification air passage 11 to the entire lower side of the dehydration tank side plate 3 </ b> A, It goes without saying that cooling water and dehumidified water flowing out from the air supply port can be surely prevented from entering the washing and dewatering tank 3.

実施の形態２．
図４は本発明の実施の形態２に係る洗濯乾燥機の除湿風路部分の構成図である。実施の形態２は、図４に示すように、洗濯兼脱水槽３の側面を構成する脱水槽側板３Ａと、洗濯兼脱水槽３の底面を構成する脱水槽底板３Ｄとの接合面に、洗濯兼脱水槽３の内部と外部とを連通させる排水孔３Ｅを設けたものである。その他の点では実施の形態１と同じである。このようにすることで、脱水槽側板３Ａの下部領域に脱水槽孔３Ｂを無くしたことにともなう、洗濯兼脱水槽３の排水能力の低下を補うことが可能となる。
なお、脱水槽側板３Ａと脱水槽底板３Ｄとの接合部を示す図４に対応する断面図を、図７に参考として示した。 Embodiment 2. FIG.
FIG. 4 is a configuration diagram of a dehumidifying air passage portion of the washing / drying machine according to Embodiment 2 of the present invention. In the second embodiment, as shown in FIG. 4, the washing surface on the joint surface between the dewatering tub side plate 3 </ b> A constituting the side surface of the washing / dehydrating tub 3 and the dewatering tub bottom plate 3 </ b> D constituting the bottom surface of the washing / dehydrating tub 3 A drainage hole 3E is provided for communicating the inside and outside of the cum dewatering tank 3 with each other. The other points are the same as those of the first embodiment. By doing in this way, it becomes possible to compensate for the decline in the drainage capacity of the washing and dewatering tank 3 due to the elimination of the dewatering tank hole 3B in the lower region of the dewatering tank side plate 3A.
In addition, sectional drawing corresponding to FIG. 4 which shows the junction part of 3 A of dehydration tank side plates and 3D of dehydration tank bottoms was shown for reference in FIG.

図５は本発明の実施の形態３に係る洗濯乾燥機の除湿風路部分の構成図である。実施の形態３は、図５に示すように、洗濯兼脱水槽３の側面を構成する脱水槽側板３Ａと、洗濯兼脱水槽３の底面を構成する脱水槽底板３Ｄとの接合面に、排水孔３Ｅを設け、さらに、脱水槽側板３Ａに、排水孔３Ｅに連通する横孔３Ｆを設けたものである。このようにしても、脱水槽側板３Ａの下部領域に脱水槽孔３Ｂを無くしたことにともなう、洗濯兼脱水槽３の排水能力の低下を補うことが可能となる。
なお、図５では、横孔３Ｆを、脱水槽側板３Ａと脱水槽底板３Ｄを固定するネジ２０の上側に設けたが、図６に示すように、横孔３Ｆをネジ２０の下側に、または、ネジ２０の上側と下側の両方に設けてもよい。 Embodiment 3 FIG.
FIG. 5 is a configuration diagram of a dehumidifying air passage portion of the washing and drying machine according to the third embodiment of the present invention. In the third embodiment, as shown in FIG. 5, the drainage tank side plate 3A constituting the side surface of the washing and dewatering tank 3 and the dewatering tank bottom plate 3D constituting the bottom surface of the washing and dewatering tank 3 are drained. A hole 3E is provided, and further, a lateral hole 3F communicating with the drain hole 3E is provided in the dewatering tank side plate 3A. Even in this case, it is possible to compensate for a decrease in the drainage capacity of the washing and dewatering tank 3 due to the elimination of the dewatering tank hole 3B in the lower region of the dewatering tank side plate 3A.
