A washing machine 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1 to 6, the washing machine 1 according to the embodiment of the present invention includes a tub 10, a dehydration tub 20, and a drain sealing mechanism 30.
The drain sealing mechanism 30 includes a drain sealing valve 31, a pulling wire 32, and an actuator 33.
First, the drain seal valve 31 according to the embodiment of the present invention is described with reference to the drawings.
As shown in fig. 1 to 6, the drain sealing valve 31 according to the embodiment of the present invention includes a valve body 100, a sealing valve plug 200, a first elastic member 300, and a second elastic member 400.
At least a portion of the sealing valve plug 200 is retractable with respect to the valve body 100, where it is understood that at least a portion of the sealing valve plug 200 is extended with respect to the valve body 100, i.e., at least a portion of the sealing valve plug 200 moves away from the valve body 100; when at least a portion of the sealing valve plug 200 is retracted relative to the valve body 100, at least a portion of the sealing valve plug 200 moves in a direction adjacent to the valve body 100. The first elastic member 300 is coupled to the valve body 100 and the at least one portion of the sealing valve plug 200, respectively, and the first elastic member 300 provides a pushing force to extend the at least one portion of the sealing valve plug 200 with respect to the valve body 100.

The valve body 100 is mounted to the tub 10 and seals the at least one portion of the valve plug 200 to correspond in position to the drain opening 21.
Specifically, when the pulling wire 32 is pulled by the actuator 33, the pulling wire 32 pulls the second resilient member 400, and the second resilient member 400 transmits a pulling force that retracts the at least a portion of the sealing valve plug 200 relative to the valve body 100 such that the at least a portion of the sealing valve plug 200 opens the drain opening 21. When the pulling wire 32 is released by the driving unit 33, the pulling force applied to the second elastic member 400 is removed, and the at least one portion of the sealing valve plug 200 is protruded with respect to the valve body 100 by the pushing force of the first elastic member 300, so that the at least one portion of the sealing valve plug 200 closes the drain opening 21.
For example, the drive device 33 may be a motor that pulls the wire 32 in the forward direction and releases the wire 32 in the reverse direction.
According to the drain sealing valve 31 of the embodiment of the present invention, not only the opening and closing of the drain port 21 of the dehydration barrel 20 can be realized, but also the opening and closing operation can be realized by the elastic force of the first elastic member 300 and the elastic force of the second elastic member 400, compared with the related art in which the structure of the cam link and the valve rod is adopted, the structure is simpler, the transmission path of the force is simplified, the transmission is simpler, the requirement for the matching precision is reduced, and the stability of the transmission is greatly improved. In addition, the first elastic member 300 provides the sealing valve plug 200 with a pushing force for closing the drain opening 21, which is more continuously and reliably provided and is less affected by other factors (e.g., vibration, etc.), so that the sealing effect is more reliable. Therefore, the drain seal valve 31 for the washing machine according to the embodiment of the present invention has advantages of simple structure, stable transmission, reliable sealing, etc.
The drain sealing mechanism 30 for the washing machine according to the embodiment of the present invention has the advantages of simple structure, stable transmission, reliable sealing, etc. by using the drain sealing valve 31 for the washing machine according to the above-described embodiment of the present invention.

In some embodiments of the present invention, the washing machine 1 further includes a blocking mechanism (not shown) switchable between a state of blocking the rotation of the spin-drying tub 20 and a state of allowing the rotation of the spin-drying tub 20, the blocking mechanism being mounted to the tub 10.
Specifically, when the washing machine 1 is ready to be supplied with water and washed, the blocking mechanism is switched to a state of blocking the rotation of the dehydration barrel 20, the dehydration barrel 10 is stopped, the dehydration barrel 10 is in a stationary state, the drainage seal valve 31 closes the drainage port 21, the washing water is completely sealed in the dehydration barrel 10, only the dehydration barrel 10 contains water, and after the washing is finished, the drainage port 21 is opened by the drainage seal valve 31, and the water is drained from the drainage port 21. Thus, the washing water is only kept in the dehydration tub 10 during washing, and the water-saving feature is provided. During drainage and dehydration, the drainage port 21 is opened by the drainage seal valve 31, and most of sediment such as silt, thread scraps, particles, dirt, and the like are discharged from the drainage port 21.
The structure of the blocking mechanism is known to those skilled in the art, such as the structure described in the background of the invention, and will not be described herein.

The outer surface of the at least a portion of the sealing valve plug 200 is provided with a sealing ring 220 extending in the circumferential direction of the sealing valve plug 200, and the sealing ring 220 surrounds the drain opening 21 to improve sealability when the drain sealing valve 31 closes the drain opening 21.
