Washing machine is made of inner barrel and outer barrel in the related technology, and there are gap between inner barrel and outer barrel, this gap is being washed
Clothing machine can have washing accumulation of mud residual after being used for a long time.In order to solve this problem, most of washing machine manufacturer is rolling
A self-cleaning function is provided on cylinder, this function is usually to inject more water in bucket and heated, while interior bucket carries out height
In the rotation of 50rpm, to reach certain cleaning effect.However, this scheme cannot completely remove be deposited in inner tank theca,
Dirt on tripod, outer barrel inner wall, for this purpose, when using non-porous inner cylinder, owning there has been proposed the solution of non-porous inner cylinder
Water all inside inner cylinder, there is no water between inner cylinder and outer barrel, would not accumulate dirt yet.Wherein, in non-porous inner cylinder scheme why
Water when being dehydrated is discharged outside bucket sample, is one of problem to be solved.
Embodiment according to a first aspect of the present invention according to an embodiment of the present invention is described in detail below with reference to Fig. 1 to Fig. 8
Dehydration control assembly 100 for washing machine.
Referring to figs. 1 to Fig. 4, the dehydration control assembly 100 according to an embodiment of the present invention for washing machine, comprising: shell
1, sealing device 2 and return unit 3.
Specifically, being formed with closed cavity 11 in shell 1, and dewatering hole 12 and drainage hole 13 are formed on shell 1,
Dewatering hole 12 and drainage hole 13 are connected to cavity 11.Allow the water of washing machine during the dehydration process via dewatering hole 12 in this way
Cavity 11 is flowed through, is then discharged again via drainage hole 13.
As shown in Figures 1 to 4, sealing device 2 (is joined in open position along longitudinal direction (up and down direction referring to fig. 1)
According to the location of sealing device 2 in Fig. 4) and blocking position (referring to the location of sealing device 2 in Fig. 3) between it is removable
Ground is located in shell 1, and at the open position, dewatering hole 12 and drainage hole 13 are connected sealing device 2, and sealing device 2 is in institute
State blocking position partition dewatering hole 12 and drainage hole 13.As a result, in the open position, water in washing machine can be via
Dewatering hole 12 flows through cavity 11, is then discharged again via drainage hole 13, convenient for the water in washing machine to be discharged；In the partition position
It sets, makes washing machine that there is preferably sealing performance, so that the washing to clothing be better achieved.
Fig. 3 and Fig. 4 is simultaneously combined referring to Fig. 2, return unit 3 is connected with sealing device 2, and return unit 3 is filled often with there is driving to seal
Set 2 to the blocking position power.That is, washing machine normally washing state or it is static when, sealing device 2 is resetting
The blocking position is often under the action of part 3, so that washing machine has preferably sealing performance, convenient for cleaning clothing.
Wherein, sealing device 2 includes clump weight 21, and clump weight 21 is in dehydration control assembly 100 around being transversely to the machine direction (its
In, longitudinally can refer to up and down direction shown in Fig. 3) axis rotation revolving speed when reaching the first revolving speed, in the work of centrifugal force
Under, clump weight 21 is moved to the open position with dynamic sealing device 2.At this point, dewatering hole 12 and drainage hole 13 are connected, laundry
Machine is in dewatering state, to be easy to the water discharge in washing machine.And return unit 3 is configured in dehydration control assembly 100
When being lower than the second revolving speed around the revolving speed of the axis (the i.e. above-mentioned axis being transversely to the machine direction) rotation, sealing device 2 is located at described
Blocking position.At this point, dewatering hole 12 and drainage hole 13 separate, washing machine is in washing state or stationary state, so that washes
Clothing machine has preferably sealing performance, so as to preferably clean clothing.
Wherein, second revolving speed is lower than first revolving speed.Specifically, washing machine is generally low in static or washing
Fast (the second revolving speed) rotation, revolving speed is about 50rpm, and due to the effect of return unit 3, sealing device 2 is located at the top of cavity 11, this
