AI Technical Summary

Technical Problem

The existing washing machine inlet hoses lack a pre-filtration and easy-to-clean structure for solid particles and impurities at the connection point, which requires personnel to manually remove and install the filter screen for cleaning periodically, making cleaning inconvenient.

Method used

An installation structure for a washing machine inlet hose was designed, including a convenient filter and sewage discharge mechanism. By using the cooperation of a first ball sleeve, a first ball, a T-shaped channel and a filter screen, solid particles can be filtered and intercepted through simple rotation, and easy cleaning without disassembly is achieved. A linkage rotary drive component is used to drive the filter screen to rotate for backwash cleaning. Automatic sewage discharge is achieved by combining a flow discharge component and a sewage discharge hose.

Benefits of technology

It achieves solid particle filtration at the installation connection point to prevent clogging, and the filter screen can be easily cleaned without disassembly by simply rotating it, which improves the convenience and efficiency of cleaning and unblocking, and eliminates the need for manual disassembly and cleaning by personnel.
