しかしながら、前記特許文献１、２に記載された従来の構成では、排水口を複数有する場合、各々の排水口に対応して設けた複数の排水弁によって排水を制御し、複数の排水弁の下流で排水を合流させて排出するため、複数の排水弁を同時に開くと合流部分で排水の流れに衝突が生じ、排水を円滑に行うことが難しく、加えて、排水経路中に複数の排水弁を設けるため、構成が複雑化するという問題があった。 However, in the conventional configuration described in Patent Documents 1 and 2, when there are a plurality of drain ports, the drainage is controlled by a plurality of drain valves provided corresponding to each drain port, and downstream of the plurality of drain valves. In order to discharge the wastewater by combining the drainage at the same time, if multiple drainage valves are opened at the same time, there will be a collision in the drainage flow at the junction and it will be difficult to drain smoothly. Therefore, there is a problem that the configuration becomes complicated.

That is, in the conventional configuration described in Patent Document 3, since the drain port of the dewatering tank is connected to the downstream side of the drain valve, in the configuration in which the drain port is provided in each of the plurality of water reservoirs, one drain port is provided. It cannot be operated with each drain opening closed by the drain valve.

また、前記特許文献４に記載された従来の構成では、洗濯槽の排水弁の下流側に接続した分岐排水管に、洗濯槽と脱水槽の各々から流入した排水の流出側に第２の弁が設けられており、この弁を押し下げて各々の末端出口から流出するようにしたものであり、分岐排水管を通過する排水の円滑な流れが妨げられる。 Moreover, in the conventional structure described in the said patent document 4, it is a 2nd valve in the outflow side of the waste_water | drain which flowed in from each of the washing tub and the dehydration tub to the branch drain pipe connected to the downstream of the drain valve of a washing tub. The valve is pushed down so that it flows out from each end outlet, and the smooth flow of drainage passing through the branch drainage pipe is hindered.
