Is done. The inside diameter of the ventilation pipe 16 is the drain hose 1
5 is much smaller than the inner diameter of the pipe 5 and the pipe extends in a direction intersecting the water flow at the time of drainage.
The water flowing through the pipe 5 is hard to enter the inside of the ventilation pipe 16. However, by any chance, water may enter the ventilation pipe 16 and reach the water inlet 10. For example, in the case where pre-washing is performed with water to which detergent is not added prior to the washing operation, if the water that has flowed back into the detergent container 50 as described above at the time of drainage after the end of the pre-washing, the detergent or finishing is performed. The agent leaks undesirably, making it impossible to wash properly when washing or rinsing. However,
In the washing machine of the present embodiment, since the position of the connecting portion of the ventilation pipe 16 is considered as described above, such an undesired outflow of the detergent can be avoided.
