Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of kitchen and bathroom supplies, and particularly refers to a three-way sewer pipe. Background Art
[0002] At present, in the kitchens of modern families, usually two or more sinks are configured to facilitate the use requirements of the kitchen. And in the common double-sink design styles, both sinks are provided with independent drain outlets, and the bellows pipes connected to the bottoms of the two drain outlets finally converge through a three-way pipe and then flow out from a single drain bellows pipe.
[0003] However, the traditional three-way pipe has a relatively simple structure, and the designed structure is unreasonable. The reason is that due to considering the universality of the three-way pipe, it usually includes a vertical pipe, and a horizontal pipe is provided on the side wall of the vertical pipe and is connected. The ends of the vertical pipe and the horizontal pipe are respectively connected to the bottoms of the two sinks through bellows pipes. An anti-odor structure is usually configured at the bottom of the vertical pipe, but the kitchen waste falling into the vertical pipe is likely to splash into the horizontal pipe, resulting in the easy growth of bacteria and the generation of odor in the horizontal pipe. Summary of the Invention
[0004] The purpose of the utility model is to provide a three-way sewer pipe, which can effectively achieve the anti-odor effect, and has a simple structure and is convenient for installation.
[0005] The purpose of the utility model is achieved as follows:
[0006] A three-way sewer pipe includes a vertical pipe and a horizontal pipe connected to the side wall of the vertical pipe. An anti-odor pipe is abutted inside the opening at the outer end of the horizontal pipe. An anti-odor through hole is provided on the side of the anti-odor pipe close to the vertical pipe and is inclined. A flip cover for sealing the anti-odor through hole is hinged at the upper end of the anti-odor through hole.
[0007] The utility model is further provided that the horizontal pipe and the vertical pipe form an inclined angle less than 90°, and the kitchen waste in the horizontal pipe flows into the vertical pipe through the inclined angle.
[0008] The utility model is further provided that an overflow pipe communicating with the inside of the horizontal pipe is provided at the upper end of the horizontal pipe, and the overflow pipe is located between the vertical pipe and the flip cover.
[0009] The utility model is further provided that the vertical pipe, the horizontal pipe and the overflow pipe are integrally injection-molded.
[0010] The utility model is further provided that installation threads are provided at the upper and lower ends of the vertical pipe, the outer end of the horizontal pipe and the upper end of the overflow pipe.
[0011] The utility model is further provided that an installation bent pipe communicating with the vertical pipe is formed at the top of the vertical pipe.
[0012] The utility model is further configured such that the anti-odor pipe is disposed in the horizontal pipe in a detachable manner. A limiting notch is formed on the pipe wall at the top of the anti-odor pipe, and a limiting end adapted to the limiting notch is formed on the inner pipe wall of the horizontal pipe.
[0013] The prominent and beneficial technical effects of the utility model compared with the prior art are as follows:
[0014] For the three-way sewer pipe provided by the utility model, an anti-odor pipe is arranged in the horizontal pipe, and a flip cover is hinged at the end of the anti-odor pipe. On the premise of meeting the function of draining water in the horizontal pipe, the flip cover can effectively achieve the effect of anti-odor; and the flip cover can effectively block the garbage accumulated at the end of the horizontal pipe due to splashing in the vertical pipe, and effectively isolate the odor of this part of the garbage, avoiding the generation of peculiar smell in the horizontal pipe.

[0023] The following further describes the utility model with specific embodiments in conjunction with the drawings. Refer to Figure 1 — Figure 3 :
[0024] A three-way sewer pipe includes a vertical pipe 1 and a horizontal pipe 2 connected to the side wall of the vertical pipe 1. An anti-odor pipe 3 is abutted inside the opening at the outer end of the horizontal pipe 2. An inclined anti-odor through hole 30 is formed on the side of the anti-odor pipe 3 close to the vertical pipe 1, and a flip cover 4 for sealing the anti-odor through hole 30 is hinged at the upper end of the anti-odor through hole 30.
[0025] In the implementation process, the upper end of the vertical pipe is connected to the bottom of a water tank through a corrugated pipe, and the outer end of the horizontal pipe is connected to the bottom of another water tank through a corrugated pipe. During the water discharge process of the water tank connected to the vertical pipe, kitchen waste will splash onto the connection between the horizontal pipe and the vertical pipe. Garbage is likely to accumulate at the connection, resulting in odors. The provided odor-proof pipe 3 relies on the flip cover 4 to isolate odors. The flip cover itself falls by gravity, blocking the garbage at the connection while ensuring the normal water discharge of the water tank connected to the horizontal pipe.
[0026] Preferably, the horizontal pipe 2 and the vertical pipe 1 form an inclined angle 20 less than 90°, and the kitchen waste in the horizontal pipe 2 flows into the vertical pipe 1 through the inclined angle 20. In order to reduce the accumulated garbage at the connection, the provided inclined angle 20 can facilitate the sliding of the garbage into the vertical pipe by gravity.
[0027] Preferably, an overflow pipe 5 communicating with the inside of the horizontal pipe 2 is provided at the upper end of the horizontal pipe 2, and the overflow pipe 5 is located between the vertical pipe 1 and the flip cover 4. The overflow pipe is usually used for overflow water discharge when the water tank is full.
[0028] Preferably, the vertical pipe 1, the horizontal pipe 2, and the overflow pipe 5 are integrally injection-molded to ensure the overall structural strength and sealing performance.
[0029] Preferably, installation threads 10 are provided at both the upper and lower ends of the vertical pipe 1, the outer end of the horizontal pipe 2, and the upper end of the overflow pipe 5.
[0030] During the implementation process, the installation threads 10 are used for the threaded installation of the corrugated pipe and the odor-proof end.
[0031] Preferably, an installation bent pipe 11 communicating with the vertical pipe 1 is formed at the top of the vertical pipe 1. In the specific implementation process, the installation bent pipe 11 has a certain length, which can provide sufficient installation length for connecting to the bottom of the water tank and reduce the demand for corrugated pipes.
[0032] Preferably, the odor-proof pipe 3 is detachably arranged in the horizontal pipe 2. A limiting notch 31 is formed on the outer wall of the top of the odor-proof pipe 3, and a limiting end 21 adapted to the limiting notch 31 is formed on the inner wall of the horizontal pipe 2. The flip cover is first hinged to the odor-proof pipe 3, and then fixed in the horizontal pipe in a plug-in form. When plugging and fixing, the limiting notch abuts against the limiting end 21.
[0033] The above embodiments are only the preferred embodiments of the present invention and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
