When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the present disclosure, unless otherwise stated, the use of the directional words such as "up and down" means up and down in the space in which the washing machine 1 is in use. "inner and outer" refer to the inner and outer contours of a component or structure itself. In addition, it should be noted that terms such as "first", "second", and the like are used for distinguishing one element from another, and have no order or importance.
