Description

本発明の実施形態は、洗濯機に関する。 Embodiments of the present invention relate to washing machines.

近年、ユーザの利便性向上の要望に応えるため、洗剤や柔軟剤などの洗濯処理剤をタンク内に予め複数回分貯留しておき、洗濯運転中に必要量をタンクから自動的に水槽内へ投入する洗濯機が開発されている。ユーザがタンクに洗濯処理剤を充填したりタンクを清掃したりする際の作業性を考慮すると、タンクは洗濯機本体から取り外しできる構造であることが好ましい。しかしながらタンク内には複数回分の洗濯処理剤が貯留されるため、洗濯処理剤が充填されたタンクは比較的重くなり易い。 In recent years, in order to meet the demand for improved convenience for users, washing treatment agents such as detergents and fabric softeners are stored in the tank multiple times in advance, and the required amount is automatically charged from the tank into the water tank during the washing operation. Washing machines are being developed. Considering the workability when the user fills the tank with the washing treatment agent or cleans the tank, it is preferable that the tank has a structure that can be removed from the washing machine main body. However, since the washing treatment agent for a plurality of times is stored in the tank, the tank filled with the washing treatment agent tends to be relatively heavy.

この場合、洗濯機本体にタンクを装着する際に、正しい装着位置からずれてしまうと、タンク内の洗濯処理剤の流出不良が生じる可能性もある。そのため、ユーザによる操作を極力容易にして、タンクを確実に正しい位置に装着できることが重要である。 In this case, when the tank is mounted on the washing machine body, if the tank is deviated from the correct mounting position, the washing treatment agent in the tank may not flow out properly. Therefore, it is important to make the operation by the user as easy as possible so that the tank can be reliably mounted in the correct position.

The automatic loading device 40 has a treatment agent tank 60 capable of storing a plurality of times of the washing treatment agent, and a tank accommodating portion 50 provided in the washing machine main body 20 for detachably accommodating the treatment agent tank 60. .. The tank accommodating portion 50 has a connecting portion 51 that communicates the inside and the outside of the tank accommodating portion 50.

処理剤タンク６０は、供給口部６１１と、処理剤タンク６０の外周面を構成するタンク周壁部６１３、６１４、６１５と、傾斜部６１６と、ガイド部６１８、６２３と、を有している。供給口部６１１は、タンク底部６１２に設けられ処理剤タンク６０の外部と内部とを連通している。供給口部６１１は、処理剤タンク６０をタンク収容部５０に挿入した状態でその挿入端において接続部５１に接続される。傾斜部６１６は、タンク周壁部６１３、６１４、６１５の外側に設けられ、接続部５１に対する供給口部６１１の接続方向に対し供給口部６１１側へ向かうにつれて供給口部６１１側に近づくように傾斜している。そして、ガイド部６１８、６２３は、傾斜部６１６に対して供給口部６１１とは反対側に設けられ、接続方向に沿って形成されている。 The treatment agent tank 60 has a supply port portion 611, tank peripheral wall portions 613, 614, 615 forming an outer peripheral surface of the treatment agent tank 60, an inclined portion 616, and a guide portion 618, 623. The supply port portion 611 is provided at the bottom portion 612 of the tank and communicates the outside and the inside of the treatment agent tank 60. The supply port portion 611 is connected to the connecting portion 51 at the insertion end in a state where the treatment agent tank 60 is inserted into the tank accommodating portion 50. The inclined portion 616 is provided on the outside of the tank peripheral wall portions 613, 614, and 615, and is inclined so as to approach the supply port portion 611 side toward the supply port portion 611 with respect to the connection direction of the supply port portion 611 to the connecting portion 51. is doing. The guide portions 618 and 623 are provided on the side opposite to the supply port portion 611 with respect to the inclined portion 616, and are formed along the connection direction.

ここで、例えば処理剤タンク６０の外面を、タンク収容部５０の内面に対して隙間なく構成した場合、タンク収容部５０に対して処理剤タンク６０を挿入する際、処理剤タンク６０は、接続方向以外の方向への移動が許容されない。つまりこの場合、ユーザは、タンク収容部５０に対する処理剤タンク６０の挿入方向を、タンク収容部５０の内面に沿った方向に厳密に制御しなければならない。そのため、例えばタンク収容部５０に対して処理剤タンク６０を上下方向に抜き差しするものにおいて、タンク収容部５０を洗濯機１０の後部側に配置すると、ユーザは、洗濯機１０の後部まで手を伸ばした状態で垂直方向に処理剤タンク６０を抜き差ししなければならず、そのため非常に作業し難い。 Here, for example, when the outer surface of the treatment agent tank 60 is configured without a gap with respect to the inner surface of the tank housing portion 50, the treatment agent tank 60 is connected when the treatment agent tank 60 is inserted into the tank storage portion 50. Movement in directions other than the direction is not allowed. That is, in this case, the user must strictly control the insertion direction of the processing agent tank 60 with respect to the tank accommodating portion 50 in the direction along the inner surface of the tank accommodating portion 50. Therefore, for example, in a case where the treatment agent tank 60 is vertically inserted and removed from the tank accommodating portion 50, when the tank accommodating portion 50 is arranged on the rear side of the washing machine 10, the user reaches to the rear part of the washing machine 10. The treatment agent tank 60 must be inserted and removed in the vertical direction in the open state, which makes it very difficult to work.

一方、例えば処理剤タンク６０の外面とタンク収容部５０の内面との間に、処理剤タンク６０の回動などの動きを許容する隙間を形成すれば、ユーザは、タンク収容部５０に対して処理剤タンク６０をある程度傾けた状態で抜き差しすることができるため、タンク収容部５０の内面に沿った方向に厳密な作業が不要となり、処理剤タンク６０の抜き差しが容易になる。 On the other hand, if, for example, a gap is formed between the outer surface of the treatment agent tank 60 and the inner surface of the tank accommodating portion 50 to allow movement such as rotation of the treatment agent tank 60, the user can use the tank accommodating portion 50 with respect to the tank accommodating portion 50. Since the treatment agent tank 60 can be inserted and removed in a state of being tilted to some extent, strict work is not required in the direction along the inner surface of the tank accommodating portion 50, and the treatment agent tank 60 can be easily inserted and removed.

しかし、この構成では、処理剤タンク６０をタンク収容部５０に挿入した際、タンク収容部５０内で処理剤タンク６０が不要な方向に動いてしまい、供給口部６１１と接続部５１との位置が正確に定まらずに接続不良が生じ、その結果、洗濯処理剤の流出不良が生じることがあった。 However, in this configuration, when the processing agent tank 60 is inserted into the tank accommodating portion 50, the processing agent tank 60 moves in an unnecessary direction in the tank accommodating portion 50, and the positions of the supply port portion 611 and the connecting portion 51 are located. However, the connection failure may occur, and as a result, the outflow of the washing treatment agent may occur.

これに対し、本実施形態によれば、処理剤タンク６０は、傾斜部６１６と、ガイド部６１８、６２３と、を有している。これによれば、処理剤タンク６０をタンク収容部５０内に挿入する際、ユーザは、まず図１３に示すように、処理剤タンク６０を、供給口部６１１と接続部５１との接続方向、この場合、上下方向に対して傾けた斜めの姿勢で、タンク収容部５０に挿入することができる。そして、ユーザは、処理剤タンク６０の傾斜部６１６をタンク収容部５０の内面、この場合、収容部奥壁部５４に当てて沿わせながら処理剤タンク６０を更に挿入する。すると、処理剤タンク６０は、図１４に示すように、供給口部６１１が接続部５１側へ向くように傾斜部６１６に沿って回動する。 On the other hand, according to the present embodiment, the treatment agent tank 60 has an inclined portion 616 and guide portions 618 and 623. According to this, when the treatment agent tank 60 is inserted into the tank accommodating portion 50, the user first inserts the treatment agent tank 60 into the connection direction between the supply port portion 611 and the connection portion 51, as shown in FIG. In this case, it can be inserted into the tank accommodating portion 50 in an oblique posture tilted with respect to the vertical direction. Then, the user further inserts the treatment agent tank 60 while applying the inclined portion 616 of the treatment agent tank 60 to the inner surface of the tank storage portion 50, in this case, the back wall portion 54 of the storage portion. Then, as shown in FIG. 14, the treatment agent tank 60 rotates along the inclined portion 616 so that the supply port portion 611 faces the connection portion 51 side.

そして、ユーザが処理剤タンク６０を更に挿入すると、ガイド部６１８、６２３がタンク収容部５０の内面、この場合、収容部奥壁部５４のガイド受部５４１に当たり、タンク収容部５０内における処理剤タンク６０の前後方向の位置が定まる。これにより、処理剤タンク６０がタンク収容部５０の正しい位置に収容され、供給口部６１１と接続部５１とが正しく接続される。 Then, when the user further inserts the treatment agent tank 60, the guide portions 618 and 623 hit the inner surface of the tank accommodating portion 50, in this case, the guide receiving portion 541 of the accommodating portion back wall portion 54, and the treatment agent in the tank accommodating portion 50. The position of the tank 60 in the front-rear direction is determined. As a result, the treatment agent tank 60 is accommodated in the correct position of the tank accommodating portion 50, and the supply port portion 611 and the connecting portion 51 are correctly connected.

このように、本実施形態によれば、傾斜部６１６の作用により、タンク収容部５０に対して処理剤タンク６０を傾けた斜めの姿勢で抜き差しできるため、ユーザの操作性を向上することができる。更に、タンク収容部５０に対して処理剤タンク６０を挿入する際には、ガイド部６１８、６２３の作用により、処理剤タンク６０がタンク収容部５０の正しい位置に収容されるため、供給口部６１１と接続部５１との位置が正確に定まることができる。これらの結果、ユーザの操作性を向上しつつ、接続不良を抑制して洗濯処理剤の流出不良を抑制することができる。 As described above, according to the present embodiment, the treatment agent tank 60 can be inserted and removed in an inclined posture with respect to the tank accommodating portion 50 by the action of the inclined portion 616, so that the user's operability can be improved. .. Further, when the treatment agent tank 60 is inserted into the tank storage portion 50, the treatment agent tank 60 is housed in the correct position of the tank storage portion 50 by the action of the guide portions 618 and 623, so that the supply port portion The positions of the 611 and the connecting portion 51 can be accurately determined. As a result, it is possible to suppress poor connection and prevent poor outflow of the laundry treatment agent while improving the operability of the user.

処理剤タンク６０は、リブ６１７を有している。リブ６１７は、タンク周壁部６１３、６１４、６１５、この場合、タンク奥壁部６１４から外方に突出し、供給口部６１１と接続部５１との接続方向へ沿って伸びる棒状又は板状に形成されている。そして傾斜部６１６は、このリブ６１７の端面に設けられている。すなわち、本実施形態では、リブ６１７において、タンク収容部５０の内面と対向する端面を傾斜部６１６としている。 The treatment agent tank 60 has ribs 617. The ribs 617 are formed in a rod shape or a plate shape that protrudes outward from the tank peripheral wall portions 613, 614, 615, in this case, the tank back wall portion 614, and extends along the connection direction between the supply port portion 611 and the connection portion 51. ing. The inclined portion 616 is provided on the end surface of the rib 617. That is, in the present embodiment, in the rib 617, the end surface facing the inner surface of the tank accommodating portion 50 is an inclined portion 616.

これによれば、傾斜部６１６がタンク収容部５０の内面この場合タンク奥壁部６１４と接触する面積を極力小さいものとすることができる。そのため、傾斜部６１６とタンク奥壁部６１４との摺動による摩擦を低減することができ、処理剤タンク６０をより滑らかに挿入することができる。 According to this, the area where the inclined portion 616 contacts the inner surface of the tank accommodating portion 50 in this case, the tank back wall portion 614, can be made as small as possible. Therefore, the friction due to the sliding between the inclined portion 616 and the tank back wall portion 614 can be reduced, and the treatment agent tank 60 can be inserted more smoothly.

ここで、接続方向におけるガイド部６１８、６２３の厚みを厚くすることで、処理剤タンク６０の挿入の際のガタつきを少なくでき移動が安定する。しかし、ガイド部６１８、６２３は、前後方向の位置決めの精度を得るために、ガイド受部５４１に極力密接するように構成されているため、ガイド部６１８、６２３とガイド受部５４１との隙間は小さい。このため、ガイド部６１８、６２３の厚みが厚くなるほど、処理剤タンク６０の下方に溜まった空気がガイド部６１８、６２３とタンク収容部５０の内面との間から抜け難くなる。すると、処理剤タンク６０に圧縮された空気が反発力を生じて挿入に大きな力を要することになる。 Here, by increasing the thickness of the guide portions 618 and 623 in the connection direction, rattling at the time of inserting the treatment agent tank 60 can be reduced and the movement is stable. However, since the guide portions 618 and 623 are configured to be as close as possible to the guide receiving portion 541 in order to obtain the accuracy of positioning in the front-rear direction, there is a gap between the guide portions 618 and 623 and the guide receiving portion 541. small. Therefore, the thicker the guide portions 618 and 623 are, the more difficult it is for the air accumulated below the treatment agent tank 60 to escape from between the guide portions 618 and 623 and the inner surface of the tank accommodating portion 50. Then, the air compressed in the treatment agent tank 60 generates a repulsive force, and a large force is required for insertion.

これに対し、本実施形態によれば、タンク収容部５０は、２組のリブ規制部５６を有している。２つのリブ６１７は、処理剤タンク６０がタンク収容部５０に挿入された状態で、タンク収容部５０の内面に設けられた各組の２つのリブ規制部５６のそれぞれの間に嵌る位置に設けられている。処理剤タンク６０は、各リブ６１７がそれぞれ２組のリブ規制部５６の間に嵌り込むことで、リブ６１７とリブ規制部５６との作用によって、接続方向に対するずれ、つまり幅方向の移動が規制される。これにより、処理剤タンク６０の幅方向の中心が、タンク収容部５０の幅方向の中心と一致するように、タンク収容部５０に対する処理剤タンク６０の幅方向の位置が規定される。これによれば、タンク収容部５０に対する処理剤タンク６０の幅方向の位置も正確に定めることができる。 On the other hand, according to the present embodiment, the tank accommodating portion 50 has two sets of rib regulating portions 56. The two ribs 617 are provided at positions where the treatment agent tank 60 is inserted into the tank accommodating portion 50 and is fitted between the two rib restricting portions 56 of each set provided on the inner surface of the tank accommodating portion 50. Has been done. In the treatment agent tank 60, each rib 617 is fitted between two sets of rib regulating portions 56, and the action of the rib 617 and the rib regulating portion 56 regulates the deviation with respect to the connection direction, that is, the movement in the width direction. Will be done. Thereby, the position of the treatment agent tank 60 in the width direction with respect to the tank housing portion 50 is defined so that the center in the width direction of the treatment agent tank 60 coincides with the center in the width direction of the tank housing portion 50. According to this, the position of the treatment agent tank 60 in the width direction with respect to the tank accommodating portion 50 can be accurately determined.

このため、本実施形態によれば、ガイド部６１８、６２３及びガイド受部５４１によって前後方向の位置を正確に定めることができるだけでなく、更に幅方向の位置も正確に定めることができる。そのため、処理剤タンク６０を抜き差しする際の移動方向が安定するため、接続方向つまり上下方向におけるガイド部６１８、６２３の厚みを薄くすることができる。その結果、処理剤タンク６０の下方に溜まった空気がガイド部６１８、６２３とタンク収容部５０の内面との間から抜け易くなる。これにより、処理剤タンク６０のタンク底部６１２で空気が圧縮されることを抑制でき、小さな力で処理剤タンク６０をタンク収容部５０内に挿入することができる。 Therefore, according to the present embodiment, not only the position in the front-rear direction can be accurately determined by the guide portions 618 and 623 and the guide receiving portion 541, but also the position in the width direction can be accurately determined. Therefore, since the moving direction when inserting and removing the treatment agent tank 60 is stable, the thickness of the guide portions 618 and 623 in the connecting direction, that is, the vertical direction can be reduced. As a result, the air accumulated below the treatment agent tank 60 can easily escape from between the guide portions 618 and 623 and the inner surface of the tank accommodating portion 50. As a result, it is possible to suppress the compression of air at the tank bottom 612 of the treatment agent tank 60, and the treatment agent tank 60 can be inserted into the tank accommodating portion 50 with a small force.

接続部５１と供給口部６１１との接続方向、すなわち供給口部６１１を接続部５１に接続する際の処理剤タンク６０の移動方向は、水平方向のベクトル成分よりも鉛直方向のベクトル成分の方が大きくなるように設定されている。本実施形態の場合、接続方向は、鉛直方向に設定されている。これによれば、処理剤タンク６０をタンク収容部５０に挿入する際、処理剤タンク６０内に貯留された洗濯処理剤の重量によって接続方向への力が作用する。これにより、ユーザは、処理剤タンク６０を大きな力で押し込むことなく処理剤タンク６０をタンク収容部５０内に挿入し供給口部６１１を接続部５１に接続させることができる。 The connection direction between the connection portion 51 and the supply port portion 611, that is, the movement direction of the processing agent tank 60 when the supply port portion 611 is connected to the connection portion 51 is the vertical vector component rather than the horizontal vector component. Is set to be large. In the case of this embodiment, the connection direction is set to the vertical direction. According to this, when the treatment agent tank 60 is inserted into the tank accommodating portion 50, a force acts in the connection direction due to the weight of the washing treatment agent stored in the treatment agent tank 60. As a result, the user can insert the treatment agent tank 60 into the tank accommodating portion 50 and connect the supply port portion 611 to the connection portion 51 without pushing the treatment agent tank 60 with a large force.

ここで、処理剤タンク６０に傾斜部６１６を設けることで、前後方向に見た場合に非対称となるため、処理剤タンク６０に洗濯処理剤を貯留した状態における重心位置が、処理剤タンク６０の前後方向の中心位置から前側にずれてしまう。そこで、供給口部６１１は、処理剤タンク６０の中心位置に対して傾斜部６１６とは反対側寄りつまり前側寄りに設けられている。これによれば、供給口部６１１を、処理剤タンク６０に洗濯処理剤を貯留した状態の処理剤タンク６０の重心を通る鉛直線Ｊ上に近い位置に配置することができる。供給口部６１１には、処理剤タンク６０内の洗濯処理剤の重量による下方への力がより大きく作用するため、供給口部６１１と接続部５１とをより軽い力で確実に接続させることができる。 Here, since the treatment agent tank 60 is provided with the inclined portion 616, the position of the center of gravity in the state where the washing treatment agent is stored in the treatment agent tank 60 is the position of the center of gravity of the treatment agent tank 60 because it becomes asymmetric when viewed in the front-rear direction. It shifts from the center position in the front-back direction to the front side. Therefore, the supply port portion 611 is provided on the side opposite to the inclined portion 616, that is, on the front side with respect to the center position of the treatment agent tank 60. According to this, the supply port portion 611 can be arranged at a position close to the vertical line J passing through the center of gravity of the treatment agent tank 60 in the state where the washing treatment agent is stored in the treatment agent tank 60. Since a downward force due to the weight of the washing treatment agent in the treatment agent tank 60 acts on the supply port portion 611 more, it is possible to securely connect the supply port portion 611 and the connection portion 51 with a lighter force. can.

また、本実施形態において、処理剤タンク６０は、取手部６２４を有している。取手部６２４は、洗濯機本体２０の上面に設けられた段部２４４を構成する上段面部２４１の後方でかつ上段面部２４１の下方に設けられている。 Further, in the present embodiment, the treatment agent tank 60 has a handle portion 624. The handle portion 624 is provided behind the upper step portion 241 constituting the step portion 244 provided on the upper surface of the washing machine main body 20 and below the upper step portion 241.

これによれば、取手部６２４を段部２４４に隠してユーザから見え難くすることができる。その結果、取手部６２４を目立たないようにすることができ、洗濯機１０全体の意匠性を向上させることができる。 According to this, the handle portion 624 can be hidden in the step portion 244 to make it difficult for the user to see. As a result, the handle portion 624 can be made inconspicuous, and the design of the washing machine 10 as a whole can be improved.

取手部６２４は、洗濯機本体２０の表面から外方へ突出せずに洗濯機本体２０の内部側へ窪んだ凹形状に形成されている。この場合、取手部６２４は、バックカバー２４の上段面部２４１、下段面部２４２、及び垂直面部２４３のいずれからも突出しておらず、バックカバー２４の内方へ窪んだ凹形状に形成されている。これによれば、取手部６２４をより目立たないようにすることができ、洗濯機１０全体の意匠性を更に向上させることができる。 The handle portion 624 is formed in a concave shape that is recessed toward the inside of the washing machine main body 20 without protruding outward from the surface of the washing machine main body 20. In this case, the handle portion 624 does not protrude from any of the upper surface portion 241 of the back cover 24, the lower surface portion 242, and the vertical surface portion 243, and is formed in a concave shape recessed inward of the back cover 24. According to this, the handle portion 624 can be made less noticeable, and the design of the washing machine 10 as a whole can be further improved.

取手部６２４は、処理剤タンク６０の内部側においてユーザ側つまり前側へ向かって更に窪んだ形状に形成されている。この場合、取手部６２４は、タンク蓋６３の下方に潜り込むようにして形成されている。これによれば、ユーザは、取手部６２４の前側へ向かって更に窪んだ部分に手をかけて処理剤タンク６０を引き出すことができるため、操作性の向上を図ることができる。 The handle portion 624 is formed in a shape further recessed toward the user side, that is, the front side on the inner side of the treatment agent tank 60. In this case, the handle portion 624 is formed so as to slip under the tank lid 63. According to this, the user can pull out the treatment agent tank 60 by putting his / her hand on the recessed portion toward the front side of the handle portion 624, so that the operability can be improved.

また、図６に示すように、処理剤タンク６０がタンク収容部５０に収容された状態において、傾斜部６１６が設けられたタンク周壁部６１４における供給口部６１１側の端部と、タンク収容部５０との間に隙間Ｓ１を有している。すなわち、処理剤タンク６０がタンク収容部５０に収容された状態において、タンク周壁部６１４の下端部分と、収容部奥壁部５４との間、及びリブ６１７の下端部分と収容部奥壁部５４との間には、それぞれ隙間Ｓ１、Ｓ２が形成されている。 Further, as shown in FIG. 6, in a state where the treatment agent tank 60 is accommodated in the tank accommodating portion 50, the end portion of the tank peripheral wall portion 614 provided with the inclined portion 616 on the supply port 611 side and the tank accommodating portion. It has a gap S1 between it and 50. That is, in a state where the treatment agent tank 60 is accommodated in the tank accommodating portion 50, between the lower end portion of the tank peripheral wall portion 614 and the accommodating portion back wall portion 54, and between the lower end portion of the rib 617 and the accommodating portion back wall portion 54. Gap S1 and S2 are formed between the two.

これによれば、処理剤タンク６０をタンク収容部５０から抜き出す際に、タンク奥壁部６１４やリブ６１７の下端部分と収容部奥壁部５４との干渉を避けて処理剤タンク６０を回動させる余地を確保することができる。このため、ユーザは、より早い段階で処理剤タンク６０を手前側つまりユーザ側に回動させることができる。その結果、処理剤タンク６０をタンク収容部５０から抜き出す際の操作性を向上させることができる。 According to this, when the treatment agent tank 60 is taken out from the tank housing portion 50, the treatment agent tank 60 is rotated while avoiding interference between the lower end portions of the tank back wall portion 614 and the rib 617 and the storage portion back wall portion 54. It is possible to secure room for interference. Therefore, the user can rotate the treatment agent tank 60 toward the front side, that is, the user side at an earlier stage. As a result, the operability when the treatment agent tank 60 is taken out from the tank accommodating portion 50 can be improved.

また、図７に示すように、収容部周壁部５３、５４、５５のうちユーザから見て奥側の収容部周壁部である収容部奥壁部５４は、ユーザから見て手前側の収容部周壁部である収容部前壁部５３よりも、収容部底部５２からの高さ寸法が小さい。すなわち、収容部底部５２を基準とした収容部奥壁部５４の高さ寸法Ｈ１は、収容部底部５２を基準とした収容部前壁部５３の高さ寸法Ｈ２よりも小さい。 Further, as shown in FIG. 7, of the accommodating portions peripheral wall portions 53, 54, 55, the accommodating portion back wall portion 54, which is the accommodating portion peripheral wall portion on the back side when viewed from the user, is the accommodating portion on the front side when viewed from the user. The height dimension from the bottom portion 52 of the accommodating portion is smaller than that of the front wall portion 53 of the accommodating portion, which is the peripheral wall portion. That is, the height dimension H1 of the accommodating portion back wall portion 54 based on the accommodating portion bottom portion 52 is smaller than the height dimension H2 of the accommodating portion front wall portion 53 based on the accommodating portion bottom portion 52.

これによれば、図１６に示すように、タンク収容部５０から処理剤タンク６０を抜き出す際に、タンク前壁部６１３の下端部が収容部前壁部５３の上端部の上方へ抜けるよりも早く、タンク奥壁部６１４の下端部が収容部奥壁部５４の上端部の上方へ抜ける。そのため、処理剤タンク６０は、タンク奥壁部６１４の下端部が収容部奥壁部５４の上端部の上方へ抜けることで、収容部前壁部５３の上端部を支点に手前側へ大きく回動できるようになる。これにより、ユーザは、処理剤タンク６０をより早く手前に引き抜くことができるようになり、その結果、操作性の更なる向上を図ることができる。 According to this, as shown in FIG. 16, when the treatment agent tank 60 is taken out from the tank accommodating portion 50, the lower end portion of the tank front wall portion 613 is pulled out above the upper end portion of the accommodating portion front wall portion 53. The lower end of the tank back wall 614 quickly comes out above the upper end of the accommodation back wall 54. Therefore, in the treatment agent tank 60, the lower end portion of the tank back wall portion 614 is pulled out above the upper end portion of the accommodating portion back wall portion 54, so that the treatment agent tank 60 is largely rotated toward the front side with the upper end portion of the accommodating portion front wall portion 53 as a fulcrum. You will be able to move. As a result, the user can pull out the treatment agent tank 60 toward the front more quickly, and as a result, the operability can be further improved.

収容部周壁部５３、５４、５５のうちユーザから見て手前側の収容部周壁部である収容部前壁部５３は、接続方向に対し収容部底部５２へ向かうにつれて接続部５１に近づくように傾斜している。これによれば、処理剤タンク６０がタンク収容部５０に抜き差しされる際に、タンク収容部５０は、傾斜した収容部前壁部５３に沿って移動する。したがって、タンク収容部５０に対する処理剤タンク６０の着脱がより容易になる。 Of the accommodating portions peripheral wall portions 53, 54, 55, the accommodating portion front wall portion 53, which is the accommodating portion peripheral wall portion on the front side when viewed from the user, approaches the connecting portion 51 toward the accommodating portion bottom 52 in the connection direction. It is tilted. According to this, when the treatment agent tank 60 is inserted into and removed from the tank accommodating portion 50, the tank accommodating portion 50 moves along the inclined accommodating portion front wall portion 53. Therefore, the treatment agent tank 60 can be easily attached to and detached from the tank accommodating portion 50.

なお、上記実施形態でいわゆる縦型の洗濯機について説明したが、本実施形態は縦型の洗濯機に限られず、回転槽の回転軸が水平又は後方へ向かって下降傾斜したいわゆる横軸型のドラム式洗濯機であっても良い。
また、上記実施形態において、タンク本体６１と枠部材６２とを一体に構成しても良い。この場合、第１ガイド部６１８及び第２ガイド部６２３は１つのガイド部となる。
また、リブ６１７及びリブ規制部５６の数は上述したものに限られない。例えばタンク本体６１は１つのリブ６１７を備え、タンク収容部５０は、この１つのリブ６１７に対応した２つで１組のリブ規制部５６を備える構成でも良い。 Although the so-called vertical washing machine has been described in the above embodiment, the present embodiment is not limited to the vertical washing machine, and the rotating shaft of the rotary tub is of the so-called horizontal shaft type in which the rotating shaft is tilted horizontally or backward. It may be a drum type washing machine.
Further, in the above embodiment, the tank body 61 and the frame member 62 may be integrally configured. In this case, the first guide unit 618 and the second guide unit 623 are one guide unit.
