Abstract

The U-shaped pipe anti-overflow structure comprises a pipe body part with the upper end open and the lower end closed, a water inlet is formed in the upper end of the pipe body part, and a water outlet is formed in the side wall of the pipe body part; the top end of the first partition plate part is higher than the lower edge of the water outlet, the bottom end of the first partition plate and the bottom of the pipe body part are arranged in a spaced mode, and a first water seal cavity and a second water seal cavity with the bottoms communicated are formed in the two sides of the first partition plate part respectively; the first water seal chamber is communicated with the water inlet, and the second water seal chamber is communicated with the water outlet; and the second partition plate part is used for separating the water inlet from the water outlet, a ventilation opening communicated with the water inlet is formed between the first partition plate part and the second partition plate part, and the ventilation opening is located in the second water seal cavity. According to the U-shaped pipe anti-overflow structure, the water seal can prevent foam from overflowing from the water inlet, meanwhile, the ventilation opening can balance air pressure on the two sides of the U-shaped pipe when the pressure in the cylinder is too large, it is guaranteed that the pressure difference on the two sides is not too large, and smooth water inflow can be guaranteed when water enters again.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a U-shaped pipe overflow prevention structure and a washing machine. Background technique [0002] The existing drum washing machines generally have a water inlet device, and most of the hoses connecting the water inlet device and the outer cylinder are U-shaped pipes, which can play the role of connecting the detergent box and the inner and outer cylinder assemblies. After the U-shaped tube is adopted, the bottom of the U-shaped tube can store water and seal to provide a sealed environment for the inner cylinder. When the drum washing machine is running for drying or high-temperature heating and washing, there will be hot and humid airflow sprayed from the drum. The water seal of the U-shaped tube can prevent water vapor from overflowing into the sink, and can also prevent foam from overflowing. However, this solution is easy to cause the internal pressure of the washi...
