[0053] The washing bladder is installed inside the washing tub 2 and is made of a flexible material. An inner cavity is formed inside the washing bladder, and a washing action wall is formed on the outside of the washing bladder. Filling the inner cavity with fluid causes the washing bladder to gradually expand, and discharging the fluid from the inner cavity causes the washing bladder to gradually contract.

[0054] During washing, the preset washing object is placed inside the washing tub 2 and close to the washing action wall. By controlling the continuous filling and discharging of fluid into the inner cavity, the washing bladder continuously expands and contracts, thereby causing the washing action wall to contact and wash the preset washing object. The structure is simple, the preset washing object is not easily deformed or damaged during the washing process, the washing force covers a large area, and the washing is thorough and sufficient.

[0055] Furthermore, the washing bladder includes a first bladder wall 13, which is a washing action wall and has washing ribs 131 formed thereon; the washing ribs 131 include a plurality of them, and the plurality of washing ribs 131 are spaced apart on the first bladder wall 13.

[0056] During washing, multiple washing ribs 131 contact and wash the preset washing object; the washing ribs 131 contact and can apply washing force to the preset washing object from multiple directions, with a large contact area and high friction washing intensity, resulting in thorough washing;
