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ことがあり、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。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。   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, etc. In some cases, residual water in the route dropped and retained. 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ことなく、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している。   The present invention solves the above-mentioned conventional problems, and can appropriately charge liquid detergent and liquid finish without dripping residual water into the liquid detergent container and liquid finish container after completion of water injection. The purpose is to provide a washing machine.

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、前記水槽に内包された回転ドラムと、前記筺体の上部に配設された洗剤投入部枠体と、前記洗剤投入部枠体内に引き出し自在に収納された洗剤や液剤が収容可能な洗剤収容容器と、前記洗剤投入部枠体の上方に載設され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抜き孔を有する水抜き口部を形成し、前記水抜き口部は、前記給水弁と前記注水口との間に配置されるとともに、前記水抜き孔は、前記注水口の高さより低い位置に設けられる構成としたものである。 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, a rotating drum contained in the water tank, and an upper part of the housing. Detergent container frame installed, a detergent container that can be stored in the detergent container frame so that it can be pulled out freely, and a detergent container that can accommodate the detergent and liquid agent, and the detergent container placed above the detergent container frame A water injection lid provided with a water supply channel for supplying water to the container, a water supply valve connected to the water supply channel, a liquid finishing agent container for charging a liquid finishing agent provided in the detergent container, and A liquid finishing agent charging path through which a liquid containing the liquid finishing agent in the liquid finishing agent storage unit is discharged into the water tank by the principle of siphon, and the water injection lid is supplied with water to the liquid finishing agent storage unit Outside the liquid finish containing part in the water supply channel formed with Forming a drain port having a drain hole, and the drain port is disposed between the water supply valve and the water inlet, and the drain hole is higher than a height of the water inlet. It is set as the structure provided in a low position.

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抜き孔より、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、抜き口部の水抜き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。   Thereby, at the time of completion of water supply to the liquid finishing agent storage part, the remaining water in the water supply channel of the water injection lid is discharged most outside the liquid finishing agent storage part from the drain hole provided at the lowest position. At this time, since the water supply valve is closed and hermetically sealed, the water supply passage of the water injection lid body has a negative pressure, air flows in from the water injection port to release the negative pressure, and toward the water drain hole of the water outlet. 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 storage unit.

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ことなく、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。   In the washing machine of the present invention, the liquid detergent and the liquid finish can be appropriately charged without dripping the remaining water remaining in the water supply channel into the liquid finish containing the siphon system.

At the end of water supply to the liquid finish agent container, the remaining water in the water supply channel of the water injection lid is discharged most outside the liquid finish agent container from the drain hole provided at the lowermost 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, air flows in from the water injection port to release the negative pressure, and water flows toward the water drain hole of the water outlet. Flowing. 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.

第二の発明は、特に、第１の発明の水抜き口部は、先端に向かって細くなる略逆ハ字状に形成した構成とすることにより、注水蓋体の水抜き孔からの残水排出時、水抜き孔先端からの大気侵入を阻止することとなり、水抜き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。   In the second aspect of the invention, in particular, the water drain port portion of the first aspect of the invention is configured to have a substantially inverted C shape that narrows toward the tip, thereby remaining water from the drain hole of the water injection lid. At the time of discharge, air intrusion from the tip of the drain hole is blocked, there is no release of negative pressure from the drain hole, air flows smoothly from the water inlet, and residual water is discharged from the water inlet of the water inlet lid. It can prevent dripping.
