Description

TECHNICAL FIELD

[0001] The application relates to the technical field of kitchen sewage discharge, and in particular to a kitchen sewage discharge U-shaped pipe. BACKGROUND

[0002] In a drainage system used in a kitchen, in order to avoid the odor of a sewer being emitted into a residence through a pipeline, the pipeline is usually made into a bent pipe shape, and when water is discharged by the action of gravity, water is retained at the bent pipe, so that the water seal prevents the gas in the sewer pipe from leaking into the residence, thereby fundamentally eliminating the problem.

[0003] According to the related technology, the inventor believes that the common U-shaped pipe installation mode is single and not stable enough, and is prone to loosening and displacement due to water flow impact and other factors during long-term use, thereby affecting the drainage effect, and even causing water leakage at the connection, which brings hidden dangers to the kitchen environment, and in addition, the U-shaped pipe is blocked, and the cleaning work is extremely difficult, and impurities such as oil and food residues in the kitchen sewage are attached and accumulated on the pipe wall, and the ordinary U-shaped pipe lacks an effective self-cleaning mechanism, and the user often needs to manually clean with professional tools, which not only consumes a lot of time and energy, but also may cause the blocking problem to repeatedly occur due to incomplete cleaning, therefore, in order to solve the above problems, the application provides a kitchen sewage discharge U-shaped pipe. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the problems in the background art, the application provides a kitchen sewage discharge U-shaped pipe.

[0005] The kitchen sewage discharge U-shaped pipe provided by the application comprises a mounting seat, a U-shaped pipe and a clamping assembly, two straight slot openings for mounting the U-shaped pipe are symmetrically formed on the surface of the mounting seat, a water pump and a water tank containing cleaning liquid are also mounted on the surface of the mounting seat, a water suction pipe is connected to the water suction port of the water pump, the end of the water suction pipe away from the water pump extends into the interior of the water tank, and a drainage hose is connected to the water discharge port of the water pump.

[0006] The clamping assembly comprises a bidirectional screw rod rotatably connected to the exterior of the mounting seat, two sliding blocks are symmetrically screw-connected to the exterior of the bidirectional screw rod, an arc-shaped plate for clamping the U-shaped pipe is mounted on one side of the exterior of the sliding block, and the U-shaped pipe is located in the interior of the straight slot opening.

[0007] One of the top end sidewalls of the U-shaped pipe is connected with a connector, and the end of the drainage hose away from the water pump is connected with a connecting pipe matched with the connector.

[0008] Mounting holes are formed at the edges of the surface of the mounting seat.

[0009] A rotating handle is mounted at one end of the bidirectional screw rod.

[0010] To sum up, the present application includes the following beneficial technical effects:

[0011] 1. By opening a straight slot on the surface of the mounting seat for installing the U-shaped pipe, and providing a clamping assembly, i.e. a bidirectional screw rod connected to the outside of the mounting seat and a sliding block and an arc-shaped plate screwed with the sliding block, the U-shaped pipe can be flexibly adjusted according to the pipe diameter and clamped stably in the straight slot. This design greatly enhances the stability of the U-shaped pipe installation, effectively avoids loosening and displacement during use, reduces drainage failures caused by installation problems, and prolongs the service life of the U-shaped pipe.

[0012] 2. The water pump and the water tank containing cleaning liquid provided on the mounting seat, as well as the water suction pipe and the drainage hose connected thereto, constitute a convenient cleaning system. When the U-shaped pipe is blocked or needs regular maintenance, the water pump can be started to inject the cleaning liquid in the water tank into the U-shaped pipe through the drainage hose, which quickly and effectively removes impurities such as grease and food residues attached to the pipe wall by using the dissolving and flushing action of the cleaning liquid. Compared with the traditional manual cleaning method, it greatly saves the user's time and effort, improves the cleaning efficiency, and ensures the smoothness of the U-shaped pipe drainage.

[0023] Specifically, when the user rotates the rotating handle 14, the bidirectional screw 8 rotates. Since the outside of the bidirectional screw 8 is symmetrically connected with two sliding blocks 9, according to the screw transmission principle, when the screw rotates, the two sliding blocks 9 will move in the opposite or same direction along the axial direction of the bidirectional screw 8.
