Design method of anti-collision bucket device for washing machine

Abstract

The invention provides a design method of an anti-collision bucket device for a washing machine. The anti-collision bucket device has a guide rod and a damping sheet, and the guide rod has an unloaded section in the middle and working sections located at both ends of the unloaded section; The above design method is based on the design method of the anti-collision bucket device under the parameters of the washing machine such as the eccentric mass of the washing machine, the minimum distance between the outer cylinder and the cabinet, etc. It is mainly used to provide the damping force in the horizontal direction, which can prevent the washing machine from colliding during low-speed dehydration. It can also ensure that the noise of the whole machine will not increase due to the increased vibration transmitted to the box during high-speed dehydration. This requires that the anti-collision bucket device provide sufficient damping force when the outer cylinder vibrates greatly to avoid The outer cylinder hits the box; at the same time, the anti-collision barrel device gives a small damping force or no damping force when the outer barrel of the washing machine is within the safe amplitude of stable operation; the anti-collision barrel designed for the washing machine is deduced according to the known conditions of the washing machine The main parameters of the device.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a design method of a washing machine anti-collision bucket device. Background technique [0002] During the dehydration process of the top wheel washing machine, the rotation speed increases from zero to 700 rotations or even higher. The eccentric load caused by unbalanced clothes gradually increases with the increase of the speed, and the fundamental frequency of the excitation force corresponding to the eccentric load increases from zero to more than ten Hz. The pulsator washing machine generally has obvious natural modes around 1~3Hz. When the speed of the washing machine passes through its modal frequency, it will cause the washing machine to resonate. If the resonance phenomenon of the washing machine cannot be well controlled, it will cause the washing machine to crash or even be damaged. [0003] In order to solve the washing machine box collision pr...

AI Technical Summary

Problems solved by technology

However, when the speed of the washing machine exceeds its corresponding modal frequency and reaches a stable speed for normal dehydration work, 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
