A drainage pipe and a washing machine using the drainage pipe

Abstract

The invention relates to a drainage pipe and a washing machine using the drainage pipe. The drainage pipe comprises a first drainage pipe connected with the drainage port of a first water tank and a second drainage pipe connected with the drainage port of the second water tank; The water outlet end of the first drainage pipe is communicated with the second drainage pipe, and further includes a switching pipe which can be reciprocally arranged in the first drainage pipe, the switching pipe is arranged close to the second drainage pipe, and the switching pipe is arranged in the first drainage pipe. Move into the second drainage pipe to cut off the upstream and downstream of the second drainage pipe, connect the first drainage pipe with the downstream of the second drainage pipe, the switching pipe exits the second drainage pipe to connect the upstream and downstream of the second drainage pipe, and connect the upstream and downstream of the second drainage pipe. The first drain pipe is cut off from the second drain pipe. The present invention opens the corresponding pipeline when it is draining and closes the other non-draining pipeline, thereby avoiding the problem of backwater and further avoiding the problem of pipe blockage caused by backwater.

Description

technical field [0001] The invention relates to a drainage pipe and a washing machine applied with the drainage pipe. Background technique [0002] There are many types of drain pipes for sinks, some are suitable for single sinks, and some are suitable for double sinks. Since there is no uniform standard for the height of the double sinks of different brands and the distance between the two sink drains, each has its own design style. The existing universal sinks can only be adapted to the double sinks of a specific structure, and cannot be suitable for both sinks at the same time. Available in various sizes. [0003] The existing water tank drainage assembly also has problems such as easy blockage of the drain pipe, low drainage efficiency, and poor deodorization effect. In order to solve the above-mentioned problems, the Chinese patent "Dual Water Tank Drainage Assembly" (Application No. CN201520639456.2) with the authorization announcement number CN205000422U discloses a...

AI Technical Summary

Problems solved by technology

[0004] Although the drainage assembly with the above structure reduces the clogging problem of the drain pipe to a certain extent, the problem of easy clogging still exists because the flow cross section of the pipe is only half of the original pipe after the partition is installed.
