Problems solved by technology

However, when the speed of the washing machine exceeds its corresponding modal frequency and reaches a stable speed and the dehydration works normally, the spring will transmit the vibration on the outer cylinder to the cabinet, causing the cabinet of the washing machine to vibrate and sound, and the noise of the whole machine will increase

Embodiment 1

[0050] Such as Figure 1-3 As shown, this embodiment provides a washing machine, including a box body 1, a washing tub 2 and a water collecting device 3 arranged in the box body 1, and also includes a suspension shock absorber 4 and a shock absorption damper 5, the suspension The suspension shock absorber 4 and the shock absorber 5 are all arranged between the box body 1 and the water collecting device 3, and are respectively connected with the box body 1 and the water collecting device 3, and the suspension shock absorber 4 will collect water The device 3 is suspended in the box body 1, the shock absorber 5 supports the water collecting device 3, and the shock absorbing damper 5 and the suspension shock absorber 4 work together to reduce the friction between the washing tub 2 and the water collecting device 3. shaking.

[0051] The washing tub in this embodiment is an inner tub, and the water collecting device includes an outer tub arranged outside the inner tub. The washing ...

Embodiment 2

[0072] Such as Figure 1-3 As shown, this embodiment is a further limitation of Embodiment 1. The outer tub 3 of this embodiment includes an outer tub bottom 31 and an outer tub body 32, and the outer tub body 32 is connected to the upper part of the outer tub bottom 31; the suspension One end of the shock absorber 4 is connected to the side wall of the outer barrel body 32, and the other end is connected to the box body 1; one end of the shock absorbing damper 5 is connected to the bottom of the outer barrel bottom 31 or the outer peripheral side wall, and the other end is connected to the box body 1. body 1 connection.

[0073] The side wall of the outer barrel body 32 is basically vertically arranged, and an outwardly protruding installation part 9 matched with the damping unit of the suspension shock absorber 4 is arranged on the side wall, and the suspension shock absorber 4 is assembled in the installation part 9 , the suspender 41 will not be hindered, and the shock-ab...

Embodiment 3

[0084] Such as Figure 1-3 As shown, this embodiment is a further limitation of Embodiment 1 or Embodiment 2. The washing machine of this embodiment also includes a horizontal shock absorber 8, and the horizontal shock absorber 8 is horizontally arranged between the outer tub 3 and the box body 1. space, and are respectively connected with the outer barrel 3 and the box body 1, reducing the vibration of the outer barrel 3 and the inner barrel 2 in the horizontal direction.

[0085]Because during the laundry process, when the rotating speed of the inner tub 2 is reduced to a certain range (generally reduced to near the resonance point), the inner tub 2 shakes seriously in the horizontal direction, and it is easy to cause the outer tub 3 to collide with the casing 1, causing the outer tub 3 to collide with the casing 1. and / or damage to enclosure 1. In order to reduce the shaking of the outer tub 3 in the horizontal direction, this embodiment is equipped with a horizontal shock...

Abstract

The invention belongs to the field of washing machines, and relates to a washing machine, comprising a box, a washing tub, a damper and a water collecting device arranged outside the washing tub. Thedamper arranged between the water collecting device and the box and respectively connected with the water collecting device and the box comprises an idle stroke and a damping stroke; when the washingtub of the washing machine is in a high-speed running state, the damper is in the idle stroke; when the washing tub of the washing machine is in a low-speed running state, the damper is in the dampingstroke; when the damper is in the damping stroke, damping force generated to the water collecting device is larger than damping force generated to the water collecting device when the damping damperis in the idle stroke. The washing machine has the advantages that the damper is mounted on the washing machine, larger damping is provided when the washing tub runs at a low speed, vibration is greatly reduced, and resonance between the box and the water collecting device is avoided; when the washing tub runs at a high speed, less damping is provided, and the energy of the water collecting deviceis prevented from being transmitted to the box.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a washing machine. Background technique [0002] A washing machine is designed as a device for washing clothes by using electricity. In general, a washing machine includes: a tub for containing washing water; a rotary tub rotatably installed inside the tub; a pulsator rotatably installed in the rotary tub The bottom; motor and clutch, are configured to rotate the rotating barrel and pulsator. When the rotary tub and the pulsator rotate in a state that laundry and detergent are introduced into the rotary tub, the pulsator agitates wash water together with the laundry introduced into the rotary tub, thereby removing stains on the laundry. [0003] During the washing process of the washing machine, when the clothes are shifted, the tub assembly in the washing machine may hit the cabinet, causing loud noise and even the displacement of the whole washing machine. [0004]...
