Washing machine

A washing machine includes: a main body; an outer tank supported in the main body in a vibration-isolating manner; a washing and dewatering tank rotatably supported in the outer tank; a liquid agent housing (5) which is formed in a substantially box shape and which supplies the liquid agent introduced therein to the outer tank or the washing/dewatering tank; and a water injection device that injects water into the liquid agent housing (5). The inside of the liquid agent housing (5) is provided with a discharge path which is formed in a substantially inverted U shape and discharges the liquid inside to the outside by the siphon principle, and a wall (31) extending vertically is formed between the position where water in the water injection device falls and the discharge path. 本发明的洗衣机具备：主体；外槽，其隔振支承于主体内；洗涤兼脱水槽，其旋转自如地支承于外槽内；液剂壳体(5)，其形成为大致箱状，将被投入至内部的液剂向外槽或洗涤兼脱水槽内供给；以及注水装置，其向液剂壳体(5)注水。在液剂壳体(5)的内部设有排出路径，该排出路径形成为大致倒字母U形，通过虹吸原理将内部的液体向外部排出，在注水装置的水落下的位置与排出路径之间形成有沿上下延伸的壁(31)。
