Problems solved by technology

During the dehydration process of the washing machine, as the clothes are gradually dried, the rotation speed of the clothes in the drum gradually slows down. During this process, the rotation speed of the clothes will be close to the natural frequency of the washing machine for a certain period of time. At this time, the washing machine will violently Vibration, at present, the solution to this problem is to arrange a heavy stone in the shell of the washing machine to suppress the vibration of the washing machine; the actual effect is that this method not only makes the washing machine heavy, but the effect is not obvious, and the vibration noise of the washing machine is still very loud.

Embodiment 1

[0018] figure 1 Shown is the first embodiment of this anti-resonance washing machine, which includes a housing 1; the middle and bottom of the housing 1 are respectively provided with a cylinder 2 with a dehydration hole and a drive motor 3; the drive motor 3 directly drives The cylinder 2; the cylinder 2 is enclosed in a water chamber, and a thin-walled cylindrical cavity 4 is formed between the inner wall of the water chamber and the outer wall of the cylinder 2; the thin-walled cylindrical cavity A drain pipe 5 extends upward from the bottom of the chamber 4 , and the drain pipe 5 passes through the middle and upper part of the water chamber and extends to the lower end outside the housing 1 .

[0019] A water pump 51 is also connected in series in the drain pipe 5, and its pumping direction is from the inside of the thin-walled cylindrical cavity 4 to the outside of the housing 1; so that the water in the thin-walled cylindrical cavity 4 cannot be discharged When it is pu...

Embodiment 2

[0023] figure 2 Shown is Embodiment 2 of the present invention, which is different from Embodiment 1 in that: a restraint cylinder 41 is fixed between the cylinder body 2 and the water chamber, and the inner wall of the restraint cylinder 41 is close to the cylinder The outer wall of the body 2, and the surface of the constraining cylinder 41 is covered with water holes, and the constraining cylinder 41 is used to constrain the cylinder body 2 and prevent it from shaking when it rotates.

Abstract

The invention provides a resonance-restrained washing machine, which comprises a shell. The middle part and the bottom part of the shell are respectively provided with a barrel and a drive motor, wherein the barrel is provided with dewatering holes; a thumb wheel at the bottom part of the barrel is driven by the drive motor or the barrel is directly driven by the drive motor; the barrel is enclosed in a water cavity; a thin-walled cylindrical cavity is formed between the inner wall of the water cavity and the outer wall of the barrel; a drain pipe extends upwards at the bottom part of the thin-walled cylindrical cavity; and the drain pipe extends straightly to the lower end of the exterior of the shell after passing through the middle-upper part of the water cavity. Resonance can be restrained during the dewatering process of the washing machine, and therefore, the washing machine is more stable and quiet when in use.

Description

[0001] technical field [0002] The invention relates to the field of household appliances, in particular to a washing machine. [0003] Background technique [0004] Washing machine is a kind of household electrical appliance that is generally used, and there are many types at present, but its principle is similar, all comprises a cylinder that can make clothing rotate inside, and a drive motor. During the dehydration process of the washing machine, as the clothes are gradually dried, the rotation speed of the clothes in the drum gradually slows down. During this process, the rotation speed of the clothes will be close to the natural frequency of the washing machine for a certain period of time. At this time, the washing machine will violently Vibration, at present, the solution to this problem is to arrange a heavy stone in the shell of the washing machine to suppress the vibration of the washing machine; the actual effect is that this method not only makes the washing ma...
