The water exchange between the inner cylinder and the inner cylinder may cause bacteria to remain and cause harm to human skin. Therefore, the inner drum of the current washing machine is set in a non-porous form, that is, the inner drum is provided with a drain outlet with a drain valve. Only when draining or dehydrating, water can be discharged from the drain outlet through the drain valve without causing any damage to the outer drum. Water enters the inner cylinder, so that the water between the inner and outer cylinders will not communicate with each other to avoid bacterial residue.

It should be noted that the drain valve provided at the drain outlet can open and close the drain outlet mainly by controlling the opening and closing of the drain valve. More specifically, the drain valve assembly includes a valve core, a driving mechanism, a valve seat, and seals. When used specifically, the valve core is used to seal the drain port. The valve core has a drainage position for opening the drain outlet and a sealing position for sealing the drain outlet, and the driving mechanism drives the valve core to switch between a sealing position for sealing the drain outlet and a drainage position for opening the drain outlet. During the washing process or when drainage is not required, the valve core is in the sealing position, sealing the drain outlet, and the water in the inner cylinder will not be drained; when drainage or dehydration is required, the valve core switches from the sealing position to the drainage position. , the drain port opens, and the water in the inner cylinder can be discharged through the drain port. For the specific structure and control principle of the drain valve, please refer to the description in the related art. This embodiment only provides a brief description of this.

However, when current washing machines are draining or dehydrating, part of the water in the inner cylinder may remain in the inner cylinder, resulting in poor drainage or dehydration effects and poor user experience.
