Problems solved by technology

In this case, the inner tub cannot rotate relative to the outer tub; when the load in the inner tub shakes due to the rotation of the laundry, there is also a hidden danger of shaking in the sealing structure, which may cause water leakage
[0004] In addition, with the improvement of living standards, users have higher and higher requirements for the washing effect of clothes. The existing washing machines basically use the pulsator to rotate and stir the water flow to wash clothes during the washing or rinsing process. The water flow formed by this washing method Relatively simple, the washing effect needs to be improved

Embodiment 1

[0040] Such as Figure 1-Figure 6 As shown, the washing machine of this embodiment includes an inner tub 500 and a water collecting device 800. A drainage hole is provided at the bottom of the inner tub 500. During the washing process, there is no water between the inner tub 500 and the water collecting device 800. During the drainage process and the dehydration process, the inner tub 500 The water in the water enters the water collecting device 800 and is discharged therefrom.

[0041] The inner bucket of the washing machine in this embodiment is used as a water bucket, so the inner bucket adopts a "non-porous" design, and the outer bucket is canceled and the water collecting device only collects the drainage of the inner bucket for discharge. Therefore, the washing machine of this embodiment has the following technical effects:

[0042] 1. The capacity of the inner tub can be increased while the volume of the shell remains unchanged, so as to realize the expansion effect of ...

Embodiment 2

[0060] Such as Figure 7-Figure 9 As shown, the drainage device of a washing machine in this embodiment, the washing machine includes an inner tub 500, and a drainage hole is provided at the bottom of the inner tub 500, and the drainage sealing device includes a sealing mechanism that can be sealed and matched with the drainage hole, and the sealing mechanism Including a blocking part and a driving part 900, the blocking part includes a blocking part 100 and a support part 600, the support part 600 is fixedly installed at the bottom of the inner tub and extends to the drain hole, and the blocking part 100 can be relatively slidably installed on the support part 600 on:

[0061] When washing or rinsing, the sealing member 100 is tightly fitted with the drainage hole, and the inner bucket contains washing water; when draining, the sealing member 100 opens the drainage hole, and the washing water in the inner bucket is discharged from the drainage hole.

[0062] The drainage sea...

Embodiment 3

[0092] Such as Figure 10-Figure 13 As shown, the drainage device of this embodiment includes a sealing mechanism and a locking mechanism. The sealing mechanism includes a blocking part and a driving part. The blocking part is installed on the drain to keep it normally closed. The driving part has a The output end of the reciprocating movement in the direction parallel to the axis, the locking mechanism locks and positions the inner barrel, the output end of the driving part reciprocates, the blocking part is pushed out to open the drain hole / reset to close the drain hole; The water collecting device has a common installation part for installing the driving parts of the locking mechanism and the sealing mechanism at the same time.

[0093] In this embodiment, the driving parts of the locking mechanism and the sealing mechanism are integrated and installed on the common installation part of the water collecting device, which simplifies the overall structure of the water collect...

Abstract

The invention provides a drainage device for a washing machine, a washing machine and a control method thereof. The washing machine includes an inner tub and a water collecting device. A drainage hole is provided at the bottom of the inner tub. During the washing process, there is no water between the inner tub and the water collecting device, and the drainage process and dehydration During the process, the water in the inner bucket enters the water collecting device and is discharged therefrom. The drainage device includes a sealing mechanism and a locking mechanism. The sealing mechanism includes a blocking part and a driving part. The blocking part is installed on the drain to keep it normally closed, and the driving part has a reciprocating motion along a direction parallel to the central axis of the inner tub. The locking mechanism locks and positions the inner barrel, the output end of the driving part reciprocates, and the blocking part is pushed out to open the drain hole / reset to close the drain hole; the water collecting device has a Install the common mounting part of the driving parts of the locking mechanism and the sealing mechanism at the same time.

Description

technical field [0001] The invention relates to the technical field of drainage of a washing machine with a non-porous inner tub, in particular to a drainage device for a washing machine, a washing machine and a control method thereof. Background technique [0002] The structure of the existing washing machine generally includes two parts, an inner barrel and an outer barrel. The inner barrel and the outer barrel are connected. The inner barrel is provided with a dehydration hole for dehydration, and the outer barrel is closed as a water tank. In this way, when the washing machine is working, the area between the inner tub and the outer tub is full of water. During the long-term use and operation of the washing machine, the area between the inner tub and the outer tub will be covered with dirt and lint in the water. Years of use will produce bacteria and odors, which will have a great impact on the washing effect and user experience. [0003] In order to solve the pollution...
