Washing machine anti-collision barrel device and washing machine

Abstract

The invention provides a washing machine anti-collision barrel device and a washing machine. The anti-collision barrel device comprises a guiding sleeve and a guiding rod of which one end extends intothe guiding sleeve, the inner side of the guiding sleeve is provided with a damping piece cooperating with the guiding rod to generate a damping force, the guiding rod has an empty section in the middle and working sections at both ends of the empty section, the diameter of the empty section is smaller than the inner diameter of the damping piece, and the diameter of the working sections is larger than the inner diameter of the damping piece; by providing the empty section and the working sections, a variable damping force is provided, and when an outer tube vibrates greatly, the anti-collision barrel device gives sufficient damping force to prevent the outer tube from colliding with a box; in the safety amplitude of stable operation of the outer tube of the washing machine, the anti-collision barrel device gives less damping force or no damping force, which can prevent the washing machine from colliding with the box at the time of low-speed dehydration, and can ensure that the noiseof the whole machine is not increased if the vibration transmitted to the box is increased when the high-speed dehydration is performed.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to an anti-collision barrel device for a washing machine and a washing machine with the anti-collision barrel device. Background technique [0002] At present, the vibration reduction of the washing machine is mainly to hang the inner and outer tubs of the washing machine by hanging the booms at the four corners of the washing machine. During the washing and dehydration process, the inner and outer tubs reduce the vibration by compressing the booms, and the booms consume the inner and outer tubs through their own damping. vibration. However, the use of the boom can only buffer the vibration in the vertical direction, and cannot reduce the lateral vibration, resulting in a collision under large eccentricity, which affects the volume ratio and starting ability of the washing machine. [0003] During the dehydration process of the top wheel washing machine, the ro...

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
