Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bathroom products, and concretely relates to a tee bend water drainer with replaceable joint. BACKGROUND

[0002] With the increase of household appliances, the pipeline for drainage is also increasing, for example, water purifier, dishwasher, washing machine, wall-mounted washing machine, dryer, sweeper, etc. all need to occupy a place in the drainage pipeline. When building a house, the number of sewer outlets is limited. If each drainage pipe is separately installed with a sewer outlet, not only the occupied area is large, but also the appearance is affected, and the decoration cost will also be greatly increased. If each drainage pipe is directly inserted into the same sewer outlet, it is difficult to fix each drainage pipe, and there is also the problem of reverse odor, peculiar smell, and the drainage pipe may even come out of the sewer outlet, causing sewage overflow.

[0003] Therefore, many integrated sewer devices have been introduced on the market, such as the tee bend drain joint disclosed in Chinese patent CN211006968U, which includes a first connecting part for connecting with the washing machine drainage pipe, a second connecting part for connecting with other drainage pipes, and a third connecting part for connecting with the sewer drain.
