It is a means to solve the problem by inclining so as to spread.

A certain amount of water always remains in the conventional bag-shaped annular groove 243 after washing and drying are completed, giving a user an unpleasant feeling. In addition, there is a problem that foreign substances such as buttons and coins enter the groove after the operation is completed. With the configuration of the present embodiment, the water in the annular groove 243 always flows toward the drum 2.

Therefore, it is possible to prevent water from remaining in the lower part of the annular groove 243 after the operation is completed, to prevent the clothes from being dehydrated and wet when the clothes are taken out, and to prevent foreign matters such as buttons and coins from being removed. It can be prevented from entering the annular groove 243. Further, since there is no need to change the connection method between the outer box 1 and the water tank 4, there is no need to largely review the structure.
