Embodiment 1

[0025] figure 1 It is a configuration diagram of the anti-vibration damper of the drum-type washing machine in Embodiment 1 of the present invention. The other components of this drum-type washing machine are the same as those of the existing drum-type washing machine, and will not be described in detail here.

[0026] Such as figure 1 As shown, the anti-vibration damper 20 in Embodiment 1 includes: a hydraulic damping mechanism 21 in which hydraulic oil is sealed in a hydraulic cylinder, and a coil spring mechanism 22 coaxially arranged with the hydraulic damping mechanism 21 . The lower end of the hydraulic damping mechanism 21 is fixed with a supporting shaft 23, and the outer periphery of the supporting shaft 23 is provided with a coil spring mechanism 22, and is fixed on the bottom 14 of the fixed side of the washing machine body 8 by means of a liquid-enclosed lower buffer material 25. In addition, the (upper) second support shaft 23a constituting the hydraulic dampe...

Embodiment 2

[0038] image 3 It is a structural schematic diagram of the anti-vibration damper 30 in Embodiment 2 of the present invention. The other components of the drum washing machine are the same as Figure 6 The prior art shown in is the same, so it will not be repeated here.

[0039] Such as image 3 As shown in , the anti-vibration damper 30 in this embodiment includes: a hydraulic damping mechanism 31 formed by sealing hydraulic oil in a hydraulic cylinder, and a coil spring mechanism 32 arranged coaxially with the hydraulic damping mechanism 31 . The lower end of the hydraulic damping mechanism 31 is fixed with a support shaft 33, and the outer periphery of the support shaft 33 is provided with a coil spring mechanism 22, and is fixed to the bottom of the washing machine body 8 by a cushioning material 35 arranged to clamp the bottom 14 of the washing machine body 8 up and down. 14. In addition, the second support shaft 33a in the hydraulic damper mechanism 31 is also fixed b...

Embodiment 3

[0054] Figure 5A It is a partial structural schematic diagram of the anti-vibration damper of the drum-type washing machine in Embodiment 3 of the present invention, and other components are the same as in Embodiment 1 and Embodiment 2, so no further description is given here. Such as Figure 5A As shown, at the lower end of the support shaft 33 of the anti-vibration damper, gaskets 37 are placed above and below the bottom 14, and two layers of cushioning materials 36 are arranged between the gaskets 37. These cushioning materials 36 are in the shape of the bottom 14. Clamped form.

[0055] The above-mentioned cushioning material 36 is formed in a double-ring shape, and a first cushioning material 36a is provided on the inner side of the support shaft 33 side, and a second cushioning material 36b is provided on the outside of the first cushioning material, forming different loss coefficients or different hardnesses. Double construction. Moreover, the shape of the 2nd buffe...

Abstract

The invention provides a drum type washing machine capable of restraining the shock transmitted to a washing machine body and effectively attenuating the shock of a water container unit. A liquid filled buffering rubber (26) is arranged at the outside of a supporting axle (23) to buffer lower materials or upper materials, so that the damping property is fully exerted in the dehydration starting process when the supporting axle moves in rotation (inclined) direction or rotates in grinding rod manner, the rotation shock of the water container unit (5) is effectively attenuated and restrained, and the shock transmitted to washing machine body and the shock of a water container unit in the dehydration starting process are restrained to realize low shock.

Description

technical field [0001] The present invention relates to a drum-type washing machine that rotates a drum containing laundry to perform various laundry operations such as washing, rinsing, and dehydration. Background technique [0002] Figure 6 A sectional view of a supporting structure of a tub unit 5 in a conventional drum type washing machine 1 is shown in . Such as Figure 6 As shown in , the structure of the above-mentioned water tank unit 5 is as follows: the water tank 3 accommodates the rotating drum 2, the rotating shaft 2a of the rotating drum 2 is supported by the bearing 6 arranged at the rear of the water tank 3, and the rotating shaft 2a and the rotating drum The driving motor 7 is connected. The tub unit 5 is installed obliquely in the washing machine body 8 with its front part tilted, and its weight is supported by two left and right anti-vibration dampers 9 mounted on the base 14 of the washing machine body 8 . At the same time, a first coil spring 10 and a...
