A washing machine spring assembly device with a spline-toothed lower spring pad

Abstract

The invention discloses a washing machine spring assembly device provided with a spline-tooth-shaped lower spring pad. The spring assembly device comprises an upper spring pad, a spring and the lower spring pad which form a spring assembly, and a protecting cover is not needed. The spring assembly is assembled between a dehydrating motor assembly and a base assembly. The upper spring pad is of a three-section structure and sequentially comprises a small conical boss, a hexagonal prism provided with a setting hole and rectangular flanges, and a cylindrical boss used for being connected with the upper end of the dehydrating motor assembly and the upper end of the spring. The lower spring pad is of a four-section structure and sequentially comprises a lower spring pad spline-tooth-shaped section, a small cylindrical boss section of the lower spring pad, a chamfered edge large boss section of the lower spring pad and a claw section of the lower spring pad. The lower spring pad is used for being connected with the lower end of the base assembly and the lower end of the spring, and the spline-tooth-shaped section is used for helping the spring assembly to achieve stability and noise reduction effects in the dehydrating operation process of a washing machine, and to achieve the vibration reduction effect in the starting and stopping processes of a dehydrating motor. The washing machine spring assembly device is simple in structure and easy to manufacture, and essentially solves the potential quality hazard existing in the spring assembly.

Description

[0001] Technical field [0002] The present invention relates to the technical field of washing machine devices, in particular to a washing machine spring assembly device with spline tooth-shaped lower spring pads. Background technique [0003] The washing machine is one of the essential household appliances in almost every household. The spring assembly is assembled between the dehydration motor assembly and the base assembly. When the washing machine is dehydrating, the spring assembly should play a role in stabilization and noise reduction; at the same time, the spring assembly should play a role in damping vibration during the start and stop of the dehydration motor. In the existing design, the outer side of the spring in the spring assembly is wrapped with a protective sleeve made of rubber material, which has a damping effect. However, when the dehydration motor is running at high speed, the friction between the spring and the protective sleeve is large, and the protect...

Problems solved by technology

[0005] In order to overcome the existing problems in order to ensure the normal operation of the washing machine for dehydration, when consumers request for repairs, new spring components are replaced, which increases the cost of use; in order to prolong the service life of the protective cover, the thickness of the protective cover is increased, which increases the manufacturing cost. ; Patent CN203214742U application discloses a kind of wear-resistant motor spring assembly protective sleeve, which discloses that the inner surface is a tooth surface protective sleeve, but it only prolongs the service life of the protective sleeve, and does not essentially solve the quality hidden dangers of the spring assembly. Defect, the present invention provides a washing machine spring assembly device with a spline-toothed lower spring pad
