Description

Technical Field

[0001] The invention relates to the technical field of drainage pumps, in particular to a rotary sleeve type double-outlet drainage pump. Background Art

[0002] In modern family life, washing machines, as a common household appliance, have greatly reduced people's laundry burden. During the operation of the washing machine, the drainage system plays a vital role. It needs to discharge the sewage generated during the washing process in a timely and effective manner. Traditional washing machine drainage pumps usually adopt a single outlet design, which can meet basic drainage needs to a certain extent.

[0003] As people's living standards improve and demands for washing machine functions diversify, some washing machine drain pumps with dual water outlets have gradually entered the market. This type of drain pump can discharge sewage to different locations according to different needs. For example, in some cases, relatively clean rinse water can be collected for other purposes, while washing sewage containing more dirt can be discharged into a specific sewage pipe. This dual water outlet design provides users with more convenience and choices.

[0004] However, there are still many problems with the existing dual-outlet drainage pumps. For example, the switching structure of some drainage pumps is relatively complicated, requiring users to perform tedious manual operations, such as disassembling and reconnecting pipes, which is not only inconvenient to operate, but also prone to water leakage and other problems. In addition, although some drainage pumps use electric switching devices, due to unreasonable design, the switching process is not smooth enough, and there may even be jamming or incomplete switching, which affects the user experience;

[0005] In addition, after long-term use, a large amount of impurities such as dirt, hair and fiber are likely to accumulate inside the drain pump of the washing machine. If these impurities are not cleaned in time, they will block the drainage pipe, affect the drainage effect, and even cause damage to the drain pump. However, the existing double-outlet drain pump has great difficulties in cleaning and maintenance. Due to the limitations of its structural design, the small internal space and the unreasonable setting of the cleaning interface, it is difficult for users to fully and effectively clean the inside of the drain pump.
