Therefore, on one hand, the washing machine keeps no water between the inner barrel and the outer barrel in the washing/rinsing process, on the other hand, impurities such as silt accumulated in the washing process can be discharged from the water discharging hole 18 in the dewatering process, and the washing efficiency is improved.
The drainage sealing device of the embodiment opens the drainage hole 18 by utilizing the centrifugal force during dehydration, has simple structure and lower cost, and can effectively solve the problem that silt can not be discharged.
As a preferred embodiment of the present invention, the drainage sealing device comprises a sealing device 3 and a centrifugal device:

During washing/rinsing, the centrifugal block is static relative to the inner barrel, the plug body is kept in a communication pipeline between the water inlet end and the water outlet end to keep the drain hole 18 closed, and during dewatering, the centrifugal block moves under the action of centrifugal force to drive the plug body to move out of the communication pipeline between the water inlet end and the water outlet end to open the drain hole 18.
The centrifugal block of the embodiment drives the plug body of the sealing device 3 to move the drain hole to open the drain hole 18 under the centrifugal force during dehydration.

Therefore, the opening force F of the sealing device is larger than pS, which provides a theoretical basis for the selection of the sealing device. For example, when selecting a commonly used valve structure as the sealing device, the valve structure should be selected in consideration of this condition to satisfy the sealing function.
Further, setting the mass of the centrifugal block as m, the distance between the centrifugal block and the rotation center of the inner barrel as a rotation radius r, and the rotation speed of the inner barrel during dehydration as n, the centrifugal force F of the centrifugal block during the dehydration rotation of the inner barrel is mr (2 pi n/60)2；
If the centrifugal force F generated by the centrifugal block is required to be used for opening the sealing device during dehydration, the following requirements are met: f + Fp > F;
the design should consider that the sealing device can be opened even in a low water level or no water state, and the following conditions should be satisfied: f is greater than F;

The plug body of this implementation still includes valve pipe 12, and valve pipe 12 telescopic setting is in valve body 17, and the corresponding setting of valve body 17 is used for the valve opening that valve pipe 12 passed, the valve opening on install valve gap 13 in order to realize sealed. The valve plug 16 of this embodiment is including setting up the valve plug body and the telescopic ripple section in valve pipe 12 one end, and the valve pipe 12 is lived to the ripple section parcel, and the inner wall at valve body 17 is fixed to the one end of bellows, and like this, valve pipe 12 removes and drives the motion realization of valve plug 16 and open/close.

or the bottom of the inner barrel is provided with a flange plate 1, the flange plate 1 extends towards the outside of the inner barrel to form a flange plate plane which is larger than the inner diameter of the inner barrel 7, and the bottom wall of the flange plate plane is provided with a centrifugal device.
The wash port on the upper part of the inner barrel of the embodiment is provided with a feeding opening, a balance ring 8 is arranged on the feeding opening, and one end of the inner barrel, which is close to the balance ring 8, is provided with a circle of dewatering holes. The inner part of the balance ring 1 of the embodiment extends into the inner barrel, and the dewatering holes are arranged right opposite to the balance ring 1, so that the balance ring 1 can shield the circle of dewatering holes, and the appearance of the inner barrel without holes can be kept.
The technical working principle of the washing machine without water between the inner barrel and the outer barrel is as follows:
the drainage sealing device is arranged on the flange plate 1, one end of the drainage sealing device is connected with the inner barrel 7 (if the inner barrel is of a structure that the inner barrel bottom 10 is separated from the barrel body, the drainage sealing device is connected with the inner barrel bottom 10), and the other end of the drainage sealing device is an outlet.
When washing, the inner barrel 7, the flange plate 1, the speed reduction clutch device 2 and the drainage sealing device form a watertight inner barrel, and water is contained in the inner barrel for washing clothes. The sealing device 3 inside the drainage sealing device prevents water in the inner tub from leaking out during washing.
In the washing/rinsing process, if the clothes are contaminated with foreign matters such as silt, the washed silt will sink to the bottom of the inner tub 7 due to the action of gravity.
During dehydration, the washing machine drives the inner tub 7 to rotate at a high speed. At this time, the slider 5 has a constant mass and moves outward in the direction regulated by the slide 6 by the centrifugal force. Because the slide block 5 is connected to the sealing device 3 by the pull rope 4, the sealing device 3 can be pulled apart by the centrifugal force generated by the slide block 5, and silt is discharged from the bottom of the washing machine during dewatering.
The washing machine without water between the inner and outer barrels of the embodiment:
(1) the barrel body, the inner barrel bottom 10, the flange plate 1, the speed reduction clutch device 2 and the drainage sealing device form a watertight inner barrel together, and the mutual connection parts of all the parts are reliably sealed and cannot leak water.
(2) The bottom of the inner barrel is provided with a drain hole 18 and a sealing device, so that water and silt deposited at the bottom of the inner barrel can be drained out of the bottom of the inner barrel.
(3) The key point of the invention is that the drain hole 18 at the bottom of the inner barrel can be opened only by the action of centrifugal force without any other driving device, so that the silt at the bottom of the inner barrel can be smoothly discharged.
(4) In order to exert the centrifugal force to the maximum, the connection between the moving direction of the slide block and the releasing direction of the seal is preferably through the rotation center of the inner barrel (i.e. in any diameter direction of the inner barrel).
The embodiment of the present invention is only used for explaining the principle of the whole invention, and in fact, as long as the bottom sealing of the inner barrel is removed by the action of centrifugal force, the problem of residual silt at the bottom of the inner barrel is solved while the waterless washing between the barrels is realized, and the present invention is within the protection scope of the present invention.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
