Hydraulic damper of drum washing machine

Abstract

The invention discloses a hydraulic damper of barrel washing machine, comprising hollow cylinder, forming oil cavity in the bosom; a cylinder rod penetrating and baring one end of cylinder; a wash barrel holdfast setting in another end of cylinder; a chassis support which set on the end bare cylinder of cylinder rod; as well as doing sliding movement in the bosom of cylinder, also connected in the end of cylinder rod placing inside the cylinder, and consisted by pistons of forming many oil-hole on its surface, thereinto there is at least one injection molding thing in the component part mentioned above. The hydraulic damper of barrel washing machine via improving the hydraulic damper structure of barrel washing machine, making the material of main component parts can adopt plastic injection, evidently reducing making cost of antivibrator. At the same time can produce in scores, so that improving production efficiency; the invention also improving the quality reliability of whole hydraulic damper by improving the quality of all component parts.

Description

technical field [0001] The invention relates to a drum washing machine. In particular, it relates to a hydraulic damper suitable for drum washing machines. Background technique [0002] Generally speaking, a washing machine is a household appliance that uses chemical decomposition and mechanical impact to remove stains on clothes. [0003] Washing machines are generally divided into front-load washing machines and pulsator-type washing machines. Compared with pulsator-type washing machines whose drums are rotated upright, the drum-type washing machines have a lower overall product height, and the laundry hardly entangles with each other. phenomenon, so its demand is gradually increasing. [0004] The structure of the existing drum washing machine will be described in detail below in conjunction with the accompanying drawings. [0005] figure 1 It is a structural schematic diagram of a drum washing machine in the prior art. Such as figure 1 As shown, the drum washing ma...

AI Technical Summary

Problems solved by technology

[0018] The material of the existing hydraulic damper D' of the above structure is all metal, its manufacturing cost is high, and welding process is also required, and the production efficiency is also low

At the same time, when the hydraulic damper D' is working, the resistance of the piston is relatively large, and the reliability of the product is low.

In short, there are many inconveniences in the application of hydraulic dampers
