Problems solved by technology

[0008] However, a gap is required for the two valve bodies to float, and the damper becomes longer, making it difficult to make a small drum-type washing machine
In addition, there may be a conflicting sound when the valve body and the piston are in contact

Embodiment 1

[0033] Embodiments of the present invention will be described below using FIGS. 1 to 13 . Fig. 1 is a side view of the inside of the drum type washing machine of the present invention. Fig. 2 is a front view of the interior of the drum-type washing machine of the present invention. In addition, FIG. 3 is an external view of a hanger in which a spring supporting a water cylinder and a damper are combined. The present invention is not limited to a drum type washing machine, and may be applied to a drum type washing and drying machine equipped with a drying device such as a heater or a fan.

[0034] There is an inlet for laundry in front of the cabinet 1 of the washing machine, and a door 2 is provided. By opening and closing the door 2, laundry can be taken out or put in. In addition, inside the housing 1 , the inlet side is inclined upward by 0° to 30° from the horizontal line, and a cylindrical water tank 3 with an opening on the inlet side is disposed. The opening of the ...

Abstract

The invention provides a tumbling-box washing machine which has the advantages of miniaturization, low-vibration and low noise. The tumbling-box washing machine at least comprises a water channel (3) arranged in the chassis (1) of the machine and supported by a spring and a oscillator damper (7), a washing barrel (4) which is rotatablely arranged in the water channel (3) and stores washing, and a electric motor (5) drives the washing barrel (4). The invention utilizes the oscillator damper (7) to suppress oversized vibration according to the size of the vibration of the wash channel (3), wherein, the oscillator damper (7) has the property that the vibration can be converted into large damping force of the wash channel (3) only during the wash channel (3) moves upward. Simultaneously, when the vibration is small, the aim of reducing transmitting of the vibration is attained by decreasing the damping force.

Description

technical field [0001] The invention relates to an anti-vibration device of a drum type washing machine. Background technique [0002] A general drum-type washing machine is composed of a water tub elastically supported in the washing machine cabinet, a rotatable washing tub with a rotation shaft set in the water tub at an angle of 0 to 30° relative to the horizontal line, and a washing tub arranged at the rear of the water tub and rotating to drive the washing tub. The motor structure of the cylinder is provided, and an opening for clothes is provided on the front of the case. [0003] Clothes are put into the washing tub for washing. To dry washed laundry, it is necessary to remove as much moisture as possible from the laundry before drying it. Therefore, there are many small holes on the side of the washing tub, so that the washing tub is rotated at a high speed for centrifugal dehydration. [0004] When performing centrifugal dehydration, it is difficult to disperse t...
