AI Technical Summary

Technical Problem

In multi-drum washing machines, both the main drum and the auxiliary drum are equipped with independent shock absorbers and suspension spring structures, resulting in a large number of parts, high cost, and a high probability of drum collision under extreme operating conditions.

Method used

By rigidly connecting the secondary tube to the frame assembly, vibration reduction is achieved using the inertial damping effect, reducing the number of dampers and suspension spring structures and avoiding collisions between the secondary tube and the frame assembly.

Benefits of technology

It reduces material costs, increases the safety distance between the auxiliary and main cylinders to avoid cylinder collisions, and provides more internal space for functional modules without increasing the overall size of the machine.

Abstract

The application provides a clothes processing device, and belongs to the technical field of cleaning devices. The clothes processing device comprises a drum assembly and a frame assembly, and comprises a main drum and at least one auxiliary drum. The main drum and the auxiliary drum are arranged in the frame assembly, and the auxiliary drum is rigidly connected with the frame assembly. The clothes processing device provided by the application is rigidly connected with the frame assembly, compared with the damping mode of the auxiliary drum adopting a shock absorber and a hanging spring structure, the distance between the auxiliary drum and the frame assembly required by the vibration of the auxiliary drum does not need to be reserved, and the possibility of collision between the auxiliary drum and the frame assembly does not need to be considered. In addition, since the auxiliary drum is rigidly connected with the frame assembly, the vibration amplitude of the auxiliary drum is small. In the case of not increasing the overall size of the clothes processing device, compared with the damping mode of the auxiliary drum adopting a shock absorber and a hanging spring structure, the safety distance between the auxiliary drum and the main drum is increased, and the collision between the main drum and the auxiliary drum in extreme working conditions is avoided.
