The detergent charging unit frame 140 fixes the water injection lid 130 on the upper surface, and stores the detergent storage container 121 in a space 140d formed between the water injection lid 130 so as to be freely drawn out.

洗剤投入部枠体140は、底部に洗剤液供給路141が形成されている。洗剤収容容器121に収容された洗剤に注水蓋体130から水が供給されて混合される。洗剤に水が混合された各種の洗剤混合液は、洗剤液供給路141および洗剤液供給路141に接続された給水経路26を経由して、水槽3内に送給される。   The detergent charging unit frame 140 has a detergent liquid supply path 141 formed at the bottom. Water is supplied from the water injection lid 130 and mixed with the detergent stored in the detergent container 121. Various detergent mixed liquids in which water is mixed with the detergent are fed into the water tank 3 through the detergent liquid supply path 141 and the water supply path 26 connected to the detergent liquid supply path 141.

洗剤収容容器121には、粉末合成洗剤を収容する粉末洗剤収容部122と、液体洗剤や液体漂白剤を収容する液体洗剤収容部123と、液体仕上剤を収容する液体仕上剤収容部124とを備えて構成されている。   The detergent container 121 includes a powder detergent container 122 that contains a powdered synthetic detergent, a liquid detergent container 123 that contains a liquid detergent or a liquid bleach, and a liquid finish agent container 124 that contains a liquid finish. It is prepared for.

収容部蓋板125が、液体洗剤収容部123と液体仕上剤収容部124の上方を覆っており、収容部蓋板125には、液体洗剤収容部123と液体仕上剤収容部124に対向する位置に、それぞれ液体洗剤受入口125aと液体仕上剤受入口125bとが開口されている。   The storage unit cover plate 125 covers the liquid detergent storage unit 123 and the liquid finishing agent storage unit 124, and the storage unit cover plate 125 faces the liquid detergent storage unit 123 and the liquid finishing agent storage unit 124. In addition, a liquid detergent receiving port 125a and a liquid finishing agent receiving port 125b are opened, respectively.

液体洗剤収容部123と液体仕上剤収容部124の底部には、それぞれ管状の液体洗剤投入口123bと液体仕上剤投入口124bが上方にむけて立設されている。収容部蓋板125には、それぞれ液体洗剤投入口123bと液体仕上剤投入口124bを外方より覆い、下端が液体洗剤収容部123と液体仕上剤収容部124の底面に達する円筒形状の一対の管状突出部125cが下方に向けて形成されている。   At the bottom of the liquid detergent container 123 and the liquid finish agent container 124, tubular liquid detergent inlets 123b and liquid finish agent inlets 124b are erected upward. The container cover plate 125 has a pair of cylindrical shapes that respectively cover the liquid detergent inlet 123b and the liquid finishing agent inlet 124b from the outside, and have lower ends reaching the bottom surfaces of the liquid detergent container 123 and the liquid finishing agent container 124. A tubular projecting portion 125c is formed facing downward.

注水蓋体130の下面には、給水路131を経て、液体洗剤投入部123に注水する注水口134と、液体仕上剤収容部124に注水する注水口135が形成されている。   On the lower surface of the water injection lid 130, a water injection port 134 for injecting water into the liquid detergent charging unit 123 and a water injection port 135 for injecting water into the liquid finishing agent storage unit 124 are formed through the water supply channel 131.

しかしながら、前記従来の構成では、注水終了後に注水蓋体の給水路に残った残水が、脱水時の振動などにより注水口部に流れる場合がある。それにより、サイフォン終了後の洗剤収容部に経路内残水が滴下し、留水するということがあった。   However, in the conventional configuration, the remaining water remaining in the water supply channel of the water injection lid after the water injection may flow to the water injection port due to vibration during dehydration. As a result, the residual water in the passage dripped into the detergent container after the siphon was finished, and water was sometimes retained.

サイフォン方式の液体洗剤収容部および液体仕上剤収容部に多くの残水が滴下して留水している場合、使用者に液体洗剤および液体仕上剤が水槽内に適切に投入されていないと勘違いされる、もしくは次回洗濯機使用時に、液体洗剤および液体仕上剤を投入すると同時にサイフォン現象で流れるという課題があった。   When a large amount of residual water is dripped and retained in the siphon liquid detergent container and liquid finish container, the user misunderstands that the liquid detergent and liquid finish are not properly put into the tank. In the next use of the washing machine, there is a problem that the liquid detergent and the liquid finish are introduced and at the same time the siphon phenomenon flows.

本発明は、前記従来の課題を解決するもので、注水終了後に液体洗剤収容部および液体仕上剤収容部に残水が滴下するのを抑制でき、液体洗剤および液体仕上剤投入を適切に行うことができる洗濯機を提供することを目的とする。   The present invention solves the above-mentioned conventional problems, and can prevent residual water from dripping into the liquid detergent container and the liquid finish agent container after the end of water injection, and appropriately perform the liquid detergent and liquid finish agent input. An object of the present invention is to provide a washing machine that can be used.

上記目的を達成するために、本発明の洗濯機は、筺体と、前記筺体内に揺動自在に防振支持された水槽と、前記筺体に配設された洗剤や液剤が収容可能な洗剤収容容器と、前記洗剤収容容器に給水するための給水路が配管された注水蓋体と、前記給水路と接続された給水弁と、前記洗剤収容容器に設けられた液体仕上剤を投入する液体仕上剤収容部と、前記液体仕上剤収容部内の液体仕上剤を含む液体がサイフォンの原理で前記水槽内に排出される液体仕上剤投入路とを備え、前記注水蓋体は、前記液体仕上剤収容部に給水する注水口が形成された給水路に、前記液体仕上剤収容部の外に通じる水量制御孔を有する水量制御部を形成し、前記水量制御部は、前記給水弁と前記注水口との間に配置され、前記給水弁及び水量制御部と注水口との間に仕切り壁を設けるものである。   In order to achieve the above object, a washing machine of the present invention includes a housing, a water tank that is supported in a vibration-proof manner in the housing, and a detergent container that can accommodate a detergent and a liquid agent disposed in the housing. A liquid finishing lid in which a water supply passage for supplying water to the detergent storage container is piped, a water supply valve connected to the water supply path, and a liquid finish provided in the detergent storage container And a liquid finishing agent charging path through which a liquid containing the liquid finishing agent in the liquid finishing agent storage part is discharged into the water tank by the principle of siphon, and the water filling lid contains the liquid finishing agent A water amount control unit having a water amount control hole communicating with the outside of the liquid finish storage unit is formed in a water supply passage in which a water injection port for supplying water to the unit is formed, and the water amount control unit includes the water supply valve, the water injection port, Between the water supply valve and the water volume control unit and the water inlet. In is intended to provide a partition wall.

これにより、液体仕上剤収容部に給水終了時、最下方の位置に設けられた水量制御孔より、注水蓋体の給水路の残水は最も多く液体仕上剤収容部の外に排出される。このとき、給水弁が閉じられており、密閉であるため、注水蓋体の給水路は負圧となり、負圧解除のため注水口より空気が流入し、水量制御部の水量制御孔の方に水が流れる。従って、注水蓋体の給水路に残った残水は、注水口へ流れることはなく、液体仕上剤収容部に残水が滴下することを抑制できる。   As a result, at the end of water supply to the liquid finishing agent storage portion, the remaining water in the water supply channel of the water injection lid is discharged most outside the liquid finishing agent storage portion from the water amount control hole provided at the lowest position. At this time, since the water supply valve is closed and hermetically sealed, the water supply path of the water injection lid body has a negative pressure, and air flows in from the water injection port to release the negative pressure, toward the water amount control hole of the water amount control unit. Water flows. Therefore, the residual water remaining in the water supply channel of the water injection lid does not flow to the water injection port, and it is possible to suppress the residual water from dripping into the liquid finishing agent container.

本発明の洗濯機は、サイフォン方式を用いた液体仕上剤収容部に、給水路に残った残水が滴下し、留水するのを抑制でき、液体洗剤および液体仕上剤投入を適切に行うことができる。   The washing machine of the present invention is capable of suppressing the remaining water remaining in the water supply channel from dripping and staying in the liquid finishing agent container using the siphon system, and appropriately adding the liquid detergent and the liquid finishing agent. Can do.

第1の発明は、筺体と、前記筺体内に揺動自在に防振支持された水槽と、前記筺体に配設された洗剤や液剤が収容可能な洗剤収容容器と、前記洗剤収容容器に給水するための給水路が配管された注水蓋体と、前記給水路と接続された給水弁と、前記洗剤収容容器に設けられた液体仕上剤を投入する液体仕上剤収容部と、前記液体仕上剤収容部内の液体仕上剤を含む液体がサイフォンの原理で前記水槽内に排出される液体仕上剤投入路とを備え、前記注水蓋体は、前記液体仕上剤収容部に給水する注水口が形成された給水路に、前記液体仕上剤収容部の外に通じる水量制御孔を有する水量制御部を形成し、前記水量制御部は、前記給水弁と前記注水口との間に配置され、前記給水弁及び水量制御部と注水口との間に仕切り壁を設けるものである。   According to a first aspect of the present invention, there is provided a housing, a water tank that is supported in a vibration-proof manner in the housing, a detergent container that can store a detergent and a liquid disposed in the housing, and water supply to the detergent container. A water supply lid connected to the water supply channel, a water supply valve connected to the water supply channel, a liquid finish storage unit for supplying a liquid finish provided in the detergent container, and the liquid finish A liquid finishing agent charging path through which liquid containing the liquid finishing agent in the container is discharged into the water tank by the principle of siphon, and the water injection lid is formed with a water injection port for supplying water to the liquid finishing agent container. A water amount control unit having a water amount control hole communicating with the outside of the liquid finishing agent storage unit, and the water amount control unit is disposed between the water supply valve and the water injection port, and the water supply valve In addition, a partition wall is provided between the water amount control unit and the water inlet.

これにより、液体仕上剤収容部に給水終了時、最下方の位置に設けられた水量制御孔より、注水蓋体の給水路の残水は最も多く液体仕上剤収容部の外に排出される。このとき、給水弁が閉じられており、密閉であるため、注水蓋体の給水路は負圧となり、負圧解除のため注水口より空気が流入し、水量制御部の水量制御孔の方に水が流れる。従って、注水蓋体の給水路に残った残水は、注水口へ流れることはなく、液体仕上剤収容部に残水が滴下することを抑制できる。   As a result, at the end of water supply to the liquid finishing agent storage portion, the remaining water in the water supply channel of the water injection lid is discharged most outside the liquid finishing agent storage portion from the water amount control hole provided at the lowest position. At this time, since the water supply valve is closed and hermetically sealed, the water supply path of the water injection lid body has a negative pressure, and air flows in from the water injection port to release the negative pressure, toward the water amount control hole of the water amount control unit. Water flows. Therefore, the residual water remaining in the water supply channel of the water injection lid does not flow to the water injection port, and it is possible to suppress the residual water from dripping into the liquid finishing agent container.

但し、上記構成においても、給水路の樹脂の表面状態や水の粘性、内部圧力の関係により、表面張力や分子間力が異なる状態が発生し、水量制御孔から確実に水が流れ出ず、給水路内に残水を引き起こす現象があった。   However, even in the above configuration, the surface tension and intermolecular force differ depending on the surface condition of the resin in the water supply channel, the viscosity of the water, and the internal pressure, and water does not flow out of the water volume control hole. There was a phenomenon that caused residual water in the road.

本発明では、そのような状態が発生した場合においても、仕切り壁により注水口側に水が流れることはなく、また、仕切り壁の頂点に空気孔があることにより、空気置換を確実に行われ、注水口側に残水があったとしても空気孔に流れ込むことはなく、液体仕上剤収容部に残水が滴下することを抑制できる。   In the present invention, even when such a state occurs, water does not flow to the water inlet side by the partition wall, and air is reliably replaced by the air hole at the apex of the partition wall. Even if there is residual water on the water inlet side, it does not flow into the air holes, and it is possible to suppress the residual water from dripping into the liquid finishing agent storage unit.

給水終了時、注水蓋体の給水路の残水は、給水路の最下方の位置に設けられた水量制御孔より、最も多く液体仕上剤収容部の外に排出される。このとき、給水弁が閉じられており、密閉であるため、注水蓋体の給水路は負圧となり、負圧解除のために注水口より空気が流入し、水量制御部の水量制御孔の方に水が流れる。従って、注水蓋体の給水路に残った残水は、注水口へ流れることはなく、液体仕上剤収容部に残水が滴下することを防止できる。   At the end of the water supply, the remaining water in the water supply channel of the water injection lid is discharged most out of the liquid finish agent accommodating portion through the water amount control hole provided at the lowermost position of the water supply channel. At this time, since the water supply valve is closed and hermetically sealed, the water supply path of the water injection lid body has negative pressure, air flows in from the water injection port to release the negative pressure, and the water amount control hole of the water amount control unit Water flows into the water. Therefore, the remaining water remaining in the water supply channel of the water injection lid body does not flow to the water injection port, and it is possible to prevent the residual water from dripping into the liquid finishing agent container.

水量制御部は、先端に向かって細くなる略円錐形状に形成した構成としているので、注水蓋体の水量制御孔からの残水排出時、水量制御孔先端からの大気侵入を阻止することとなり、水量制御孔からの負圧解除がなく、注水口よりの空気流入が円滑に図られ、注水蓋体の注水口より残水が滴下することを防止できる。   Since the water amount control unit is configured to have a substantially conical shape that narrows toward the tip, when discharging residual water from the water amount control hole of the water injection lid, it will prevent air from entering from the tip of the water amount control hole, There is no release of negative pressure from the water volume control hole, air can be smoothly introduced from the water injection port, and residual water can be prevented from dripping from the water injection port of the water injection lid.

特に、水量制御部の水量制御孔は、鉛直方向に対して斜めに傾斜させた開口を備え、液体仕上剤収容部の液体仕上剤を含む液体がサイフォンの原理で水槽内に排出される液体仕上剤投入路の斜め後方に向けて形成した構成としている。これにより、水槽内に排出される液体仕上剤投入路を流れる液体仕上剤を含む液体に阻害されることなく、注水蓋体の給水路に残った残水を水量制御孔からの円滑に排出され、注水蓋体の注水口より残水が滴下することを防止できる。   In particular, the water amount control hole of the water amount control unit has an opening inclined obliquely with respect to the vertical direction, and the liquid finishing liquid in which the liquid finishing agent in the liquid finishing agent container is discharged into the water tank by the principle of siphon. It is the structure formed toward the diagonally back of the agent charging path. As a result, the remaining water remaining in the water supply channel of the water injection lid is smoothly discharged from the water amount control hole without being obstructed by the liquid containing the liquid finish flowing in the liquid finish agent charging channel discharged into the water tank. The residual water can be prevented from dripping from the water inlet of the water injection lid.

以上のように構成されたドラム式洗濯機について、以下その動作、作用を説明する。   About the drum type washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

洗い工程が終わった後のすすぎ工程において、注水口33から液体仕上剤受入口25bを介して液体仕上剤収容部24に注水される。注水された水により、スタート前に予め液体仕上剤収容部24に投入された液体仕上剤が希釈拡散した状態の仕上液となる。仕上液は、管状突出部25cと液体仕上剤投入口24bとの間に形成された隙間を介して、サイフォンの原理により液体仕上剤投入口24bに導入され、液体仕上材投入口24bの下流側に形成された洗剤液供給路41を経由して、水槽3内に送給される。   In the rinsing step after the washing step is completed, water is poured from the water filling port 33 into the liquid finishing agent storage unit 24 through the liquid finishing agent receiving port 25b. With the poured water, the finished liquid is in a state in which the liquid finish previously introduced into the liquid finish storage unit 24 before the start is diluted and diffused. The finishing liquid is introduced into the liquid finishing agent inlet 24b by the siphon principle through a gap formed between the tubular protrusion 25c and the liquid finishing agent inlet 24b, and is downstream of the liquid finishing material inlet 24b. Then, the water is fed into the water tank 3 through the detergent liquid supply path 41 formed in the above.

そして、サイフォンの原理による供給終了後に、注水蓋体30の第2の給水路31bに残った残水は、最下方に配置された水量制御部35の水量制御孔36より液体仕上剤収容部24よりも外に排出される。このとき、注水蓋体30の給水路は、給水弁7が閉じられており、密閉であるため、負圧となり、負圧解除のため、注水口33より空気が流入し、水量制御部35の方に水が流れる。従って、注水蓋体30の給水路に残った残水は、注水
口33へ流れることはなく、液体仕上剤収容部24に残水が滴下することを防止できる。
And after completion | finish of the supply by the principle of siphon, the residual water which remained in the 2nd water supply path 31b of the water injection cover body 30 is liquid finishing agent accommodating part 24 from the water quantity control hole 36 of the water quantity control part 35 arrange | positioned in the lowest part. Is discharged outside. At this time, the water supply channel of the water injection lid 30 is closed because the water supply valve 7 is closed, and thus has a negative pressure. In order to release the negative pressure, air flows in from the water injection port 33 and the water amount control unit 35 Water flows to the direction. Therefore, the remaining water remaining in the water supply channel of the water injection lid 30 does not flow to the water injection port 33, and it is possible to prevent the residual water from dripping into the liquid finishing agent storage unit 24.

以上のように、本実施の形態においては、注水蓋体30は、液体仕上剤収容部24に給水する注水口33が形成された第2の給水路31bに、液体仕上剤収容部24の外に通じる水量制御孔36を有する水量制御部35を形成している。水量制御部35は、給水弁7と注水口33との間に配置するとともに、水量制御孔36は、注水口33の高さより低い位置に設けている。水量制御部35は、水量制御孔36を底部に形成した水量制御凹部42を設け、水量制御凹部42の高さは水量制御凹部42の長辺径の2倍以上に設定することにより、第2の給水路31bに残った残水が、液体仕上剤収容部24に滴下することを防止できる。   As described above, in the present embodiment, the water filling lid 30 is disposed outside the liquid finishing agent storage unit 24 in the second water supply path 31b in which the water injection port 33 for supplying water to the liquid finishing agent storage unit 24 is formed. The water quantity control part 35 which has the water quantity control hole 36 which leads to is formed. The water amount control unit 35 is disposed between the water supply valve 7 and the water injection port 33, and the water amount control hole 36 is provided at a position lower than the height of the water injection port 33. The water amount control unit 35 is provided with a water amount control concave portion 42 formed with a water amount control hole 36 at the bottom, and the height of the water amount control concave portion 42 is set to be not less than twice the long side diameter of the water amount control concave portion 42. It is possible to prevent the remaining water remaining in the water supply channel 31b from dripping into the liquid finishing agent storage unit 24.

また、水量制御部35は、先端に向かって細くなる略円錐形状に形成された水量制御凹部42の底部に水量制御孔36を形成している。これにより、注水蓋体30の水量制御孔36からの残水排出時、水量制御孔36先端からの大気侵入を阻止することとなり、水量制御孔36からの負圧解除がなく、注水口33よりの空気流入が円滑に図られ、注水蓋体30の注水口33より残水が滴下することを防止できる。   In addition, the water amount control unit 35 has a water amount control hole 36 formed at the bottom of the water amount control recess 42 formed in a substantially conical shape that narrows toward the tip. As a result, when residual water is discharged from the water amount control hole 36 of the water injection lid 30, air intrusion from the front end of the water amount control hole 36 is prevented, the negative pressure is not released from the water amount control hole 36, and the water injection port 33 The air can be smoothly flowed in, and residual water can be prevented from dripping from the water injection port 33 of the water injection lid 30.

水量制御部35の水量制御孔36は、鉛直方向に対して斜めに傾斜させた開口を備えている。水量制御部35の水量制御孔36は、液体仕上剤収容部24の液体仕上剤を含む液体がサイフォンの原理で水槽3内に排出される。水量制御部35の水量制御孔36は、開口を液体仕上剤投入路24aの斜め後方に向けた構成としている。これにより、水槽3内に排出される液体仕上剤投入路24aを流れる液体仕上剤を含む液体に阻害されることなく、注水蓋体30の第2の給水路31bに残った残水が水量制御孔36から円滑に排出され、注水蓋体30の注水口33より残水が滴下することを防止できる。   The water amount control hole 36 of the water amount control unit 35 includes an opening that is inclined obliquely with respect to the vertical direction. In the water amount control hole 36 of the water amount control unit 35, the liquid containing the liquid finishing agent in the liquid finishing agent storage unit 24 is discharged into the water tank 3 by the siphon principle. The water amount control hole 36 of the water amount control unit 35 is configured such that the opening is directed obliquely rearward of the liquid finish agent charging path 24a. Thereby, the remaining water remaining in the second water supply path 31b of the water injection lid 30 is controlled by the amount of water without being obstructed by the liquid containing the liquid finishing agent flowing through the liquid finishing agent charging path 24a discharged into the water tank 3. It is possible to prevent the residual water from dripping from the water injection port 33 of the water injection lid 30 by being smoothly discharged from the hole 36.

但し、上記構成においても、第2の給水路31bの表面状態や給水の粘度、表面張力により、負圧解除を発生させる現象が起きる可能性があり、第2の給水路31bに残水を発生させ、注水口33より給水終了後及び洗濯機運転終了後に注水口33より残水滴下することが想定された。   However, even in the above configuration, there is a possibility that a negative pressure release may occur due to the surface state of the second water supply channel 31b, the viscosity of the water supply, and the surface tension, and residual water is generated in the second water supply channel 31b. It was assumed that residual water was dripped from the water injection port 33 after the water supply end 33 and after the washing machine operation was completed.

本発明においては、上記負圧構成に加え、水量制御孔36から確実に残水流出を行うために、注水蓋体のより高い位置に空気を導入する空気孔50を設けている。また、万が一残水が発生しても、注水口33より残水滴下しない仕切り壁51を第2の給水路31bの空間高さ、または、天面壁よりも高い位置まで伸ばした寸法に形成している。これにより、経年変化等により初期状態から想定外の変化が起きても、注水口33からの残水滴下を防止することを実現した。   In the present invention, in addition to the above-described negative pressure configuration, an air hole 50 for introducing air to a higher position of the water injection lid is provided in order to reliably discharge residual water from the water amount control hole 36. In addition, even if residual water is generated, the partition wall 51 that does not drop residual water from the water injection port 33 is formed to have a dimension that extends to the height of the space of the second water supply path 31b or higher than the top wall. Yes. Thereby, even if an unexpected change has occurred from the initial state due to secular change or the like, it has been realized that dripping of residual water from the water inlet 33 is prevented.

なお、本実施の形態は、ドラム式洗濯機に基づいて説明したが、縦型洗濯機に採用してもよい。   In addition, although this Embodiment demonstrated based on the drum type washing machine, you may employ | adopt for a vertical washing machine.

以上のように、本発明にかかる洗濯機は、注水蓋体の構成により、給水路に残った残水が、脱水時の振動などでサイフォン方式を用いた洗剤収容部に滴下するのを防止できるため、サイフォン方式の洗剤収容部を持つ洗剤収容容器を備えたドラム式洗濯機のみならず、縦型洗濯機など他の洗濯機や、洗濯乾燥機の用途に適用できる。   As described above, the washing machine according to the present invention can prevent the residual water remaining in the water supply channel from dripping into the detergent container using the siphon system due to vibration during dehydration or the like due to the structure of the water injection lid. Therefore, the present invention can be applied not only to a drum-type washing machine having a detergent container having a siphon-type detergent container, but also to other washing machines such as a vertical washing machine and a washing / drying machine.
