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

[0044] like 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.

[0045] The inner tub of the washing machine of the present embodiment is used as a water tub, so the inner tub adopts a "non-porous" design, and at the same time, the outer tub is cancelled and the water collecting device only collects the drainage of the inner tub for discharge. Therefore, the washing machine of this embodiment has the following technical effects:

[0046] 1. When the volume of the shell remains unchanged, the capacity of the inner tub can be increased to realize the expansion effect of...

Embodiment 2

[0065] like Figure 7-Figure 9 As shown, in this embodiment, there is a drainage device for a washing machine. The washing machine includes an inner tub 500 with a drainage hole at the bottom of the inner tub 500. The drainage sealing device includes a sealing mechanism that can be sealed with the drainage hole. The sealing mechanism It includes a blocking member and a driving member 900. The blocking member includes a blocking member 100 and a supporting member 600. The supporting member 600 is fixedly installed at the bottom of the inner tub and extends to the drainage hole. The blocking member 100 can be relatively slidably installed on the supporting member. On 600:

[0066] When washing or rinsing, the blocking member 100 is sealed with the drainage hole, and the inner tub contains washing water; when draining, the blocking member 100 opens the drainage hole, and the washing water in the inner barrel is discharged from the drainage hole.

[0067] The drainage sealing dev...

Embodiment 3

[0097] like 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 member and a driving member, the blocking member is installed on the water outlet to keep it normally closed, and the driving member has a center along the center of the inner tub. The output end of the reciprocating motion in the direction parallel to the axis, the locking mechanism locks and locates the inner tub, 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 The water collecting device is provided with a common mounting portion for mounting the driving components of the locking mechanism and the sealing mechanism at the same time.

[0098] In this embodiment, the driving components of the locking mechanism and the sealing mechanism are integrally mounted on the common mounting portion of the water collec...

Abstract

The invention provides 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. The water enters the water collecting device and is discharged therefrom; it also includes a drainage device for realizing the drainage of the inner barrel and a water level detecting device for detecting the water level in the water collecting device. The drainage device includes a sealing mechanism and a locking mechanism, and the sealing mechanism includes a sealing mechanism. A blocking part and a driving part, the blocking part is installed on the water outlet to keep it normally closed, the driving part has an output end that reciprocates along the direction parallel to the central axis of the inner tub, and the locking mechanism locks and locates the inner tub, 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 control method of the washing machine of the present invention monitors the water level in the water collecting device during the drainage process to avoid abnormal drainage.

Description

technical field [0001] The invention relates to the technical field of drainage of non-porous inner tub washing machines, in particular to 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 bucket. 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 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. Long-term use will produce bacteria and odors, which will have a greater impact on the washing effect and user experience. [0003] In order to solve the problem of contamination of the inner tub and the outer tub c...
