Draining filtering apparatus and household electrical appliance

Abstract

The invention discloses a draining filtering apparatus including an impeller driven by a motor, a housing and a filter, a drainage chamber for receiving the impeller and a filter chamber for receiving the filter are arranged in the housing, a water inlet is arranged in the filter chamber, a water outlet for communicating the filter chamber and the drainage chamber is arranged in the filter, and the draining filtering apparatus is characterized in that the filter includes a buffer part for buffering the water flow entered into the water inlet and a filtering part for filtering impurities in the water flow. During the filtering drainage, the water flow enters into the filter chamber in a rush, and the buffer part can buffer the rushed water flow to make the water flow directly hit the filtering part smoothly, so that the impurities in the water flow cannot pass through the filtering part and can deposit naturally in the filter chamber. Therefore, the filtering effect of the filtering apparatus can be greatly improved. The invention further discloses a household electrical appliance with the draining filtering apparatus.

Description

technical field [0001] The invention relates to a household appliance operated with water, in particular to a drainage filtering device in a washing machine or a dishwasher. Background technique [0002] Generally, the front-loading washing machine adopts the upper drainage method, and the water in the bucket is discharged out of the machine through the drainage pump and the drainage pipe. When the washing machine drains water, the water in the washing machine will directly enter the housing of the drain pump, and the fibers and coins falling from the laundry will enter the housing, which will not only damage the drain of the washing machine, but also damage the drain pump. impeller, which affects the drainage efficiency of the drainage pump or the drainage pump is prone to failure. Therefore the Chinese invention patent application with publication number CN102588352A and the Chinese utility model with publication number CN202559120U have all proposed different filtration ...

AI Technical Summary

Problems solved by technology

When the washing machine drains, the water in the washing machine will directly enter the casing of the drain pump, and the fibers and coins falling from the laundry will enter the casing, which will not only damage the drain of the washing machine, but also damage the drain pump. The impeller, which affects the drainage efficiency of the drainage pump or the drainage pump is prone to failure

Therefore the Chinese invention patent application with publication number CN102588352A and the Chinese utility model with publication number CN202559120U have all proposed different filtration schemes at the above problems, but still cannot reach the effect of filtering foreign matter well, and the drainage pump is draining water simultaneously The sound produced during the process is too loud
