Preferably, the blocking component 24 further comprises a sealing gasket 25, and the sealing gasket 25 is disposed on the annular sealing portion.

In order to maintain the self-sealing of the blocking component 24 and the return sealing after the water outlet is opened, the sealing mechanism comprises an elastic component 27, one end of the elastic component 27 is abutted against the supporting component 26, the other end of the elastic component 27 is abutted against the blocking component 24, and the elastic component 27 is deformed when the blocking component 24 slides to a state of being separated from the water outlet, so that the elastic return sealing of the blocking component 24 is realized.

Preferably, the resilient member 27 is initially in a compressed state to maintain a sealing engagement between the closure member 24 and the drain opening.

In an embodiment of the present invention, the elastic member 27 is a compression spring, the compression spring is sleeved in the hollow slide of the sheathing part, one end of the compression spring abuts against the sheathing part, and the other end abuts against the blocking member 24.

This embodiment the shutoff part including the top cap, the upper end of top cap is the arc surface, the lower terminal surface of top cap have with the sealed complex sealing of outlet.

The working principle of sealing is as follows: the compression spring is compressed, one end acts on the supporting part 26, the other end acts on the fixing buckle 28, the fixing buckle 28 is transmitted to the whole blocking part 24 through the central rod of the blocking part 24, and the blocking part 24 presses the water outlet at the bottom of the barrel under the action of the spring force to achieve the sealing effect. As shown in fig. 8.

The working principle of drainage is as follows: when the water is to be drained, the inner barrel realizes the position coincidence of the sealing structure and the driving mechanism through a locking mechanism, at the moment, the output end 29 of the driving mechanism is pressed against the fixing buckle 28 to drive the top cover to move upwards, and a gap is generated between the top cover and the water outlet to realize the water drainage. The compression spring is also compressed to the extreme position at this time. After the discharge is complete, the output 29 of the drive mechanism is retracted and the top cap reseals the discharge opening under the influence of the spring force. As shown in fig. 9.

The drainage sealing device of the embodiment adopts a conical design for the inner barrel and the sealing gasket, so that when clothes are gathered near the drainage outlet, the foreign matters can be more conveniently discharged under the impact of water flow and the gravity of the foreign matters. And is also favorable for preventing the accumulation of thread scraps in long-time operation.

The sealed rubber pad is fixed on the top of the whole sealing structure, and when the foreign matters are tightly attached to the bottom of the inner barrel to be discharged, the friction damping of the inner barrel is smaller than the friction resistance of the rubber because the inner barrel is made of metal stainless steel, so that the foreign matters can be discharged more conveniently. And is also favorable for preventing the accumulation of thread scraps in long-time operation.

The support member 26 has a saddle-shaped structure to prevent foreign materials from being caught more if they contact the holder, assuming that the holder is flat, when the foreign materials are discharged out of the inner tub. The damping of the semicircular structural design is reduced, and the accumulation of the thread scraps in long-time running is also favorably prevented.

The sleeving part of the supporting part 26 can be in excessive fit with the central rod of the plugging part 24, so that thread scraps and foreign matters are effectively prevented from entering the spring cavity, and the spring is clamped when working.

Preferably, the driving mechanism may select a drain valve, and the abutting force of the drain valve is larger than the diameter of the inner cylinder of the fixing buckle 700, so as to ensure that the abutting thrust of the drain valve acts on the fixing buckle, and prevent the thrust from directly acting on the central rod of the plugging component 100, which may cause a falling-off problem. Here, the fixing can also be realized by screw thread fit and elastic buckle.

Further, as shown in fig. 5, a locking hole 16 for locking the inner tub by cooperating with a locking mechanism 17 is formed in an outer wall of a bottom of the inner tub, and the washing machine further includes a locking mechanism mounted on the water collecting device, the locking mechanism having a locking rod moving up and down, the locking rod moving up and being inserted into the locking hole to lock the inner tub, and then an output end of the driving device is extended to push the sealing mechanism open to drain water.
