Technical Field

The invention relates to a drainage pipeline and a cleaning machine with the drainage pipeline.

Background

The drainage pipes of the water tank are various, and are matched with a single water tank and also matched with a double water tank and a triple water tank. Because the height of the double water tanks with different brands and the distance between the two water tank water outlets do not have a unified standard, each family has own design style, and the existing universal water tank can only be matched with the double water tanks with specific structures and can not be matched with various sizes at the same time.

The existing water tank drainage assembly also has the problems that a drain pipe is easy to block, the drainage efficiency is low, the deodorization effect is not good, and the like. In order to solve the above problems, chinese patent "a double water tank drainage assembly" (application no: CN201520639456.2), entitled publication No. CN205000422U, discloses a structure comprising a first drainage pipeline connected to a drainage port of a first water tank, a second drainage pipeline communicated to a drainage port of a second water tank, and a sewer pipeline, wherein an outlet of the first drainage pipeline is connected to a first port on a main pipe of a three-way pipeline, an outlet of the second drainage pipeline is connected to a second port on a branch pipe of the three-way pipeline, and a third port on the main pipe of the three-way pipeline is connected to the sewer pipeline through a trap; the three-way pipeline is also internally provided with a first clapboard which divides the inner cavity of the three-way pipeline into a first channel communicated with the first port and a second channel communicated with the second port, and the outlets of the first channel and the second channel are communicated with the inlet of the trap.

The drainage assembly with the structure reduces the blockage problem of the drainage pipe to a certain extent. However, in actual use, it is found that such a problem still exists in the user's home: when the functional tank body for cleaning dishes, fruits and vegetables is not frequently used, but another common water tank is frequently used, due to the fact that the water drainage speed is low, oil stains and the like discharged from the common water tank easily flow into the transverse drain pipe of the functional tank body connected with the common water tank, and after a long time, the transverse drain pipe is blocked by a mixture of grease and food residues, so that normal use of the functional tank body is affected, and peculiar smell is generated.

Therefore, further improvements are needed in the current drain assembly structures for double or multiple sinks.
