Description
Technical Field
[0001] The utility model relates to the technical field of toilet drainage, in particular to a caisson with buffering and drainage functions. Background Art
[0002] For bathrooms with caissons, if there are multiple drainage points such as shower room floor drains, wash basin floor drains, and dry area floor drains, a water trap is usually installed at the drainage transverse pipe of each drainage point. However, it was found during use that this is prone to the following problems: first, since the dry area floor drain and bathtub are used less frequently, the water in the water trap will evaporate and then become smelly; second, when taking a shower in the shower room, it is easy for hair and other impurities to be brought into the water trap, and the water trap will be blocked because the shower room drainage has no impact; third, the caisson needs to pre-embed multiple drainage transverse pipes, and too many interfaces between the floor drain and the drainage transverse pipes may easily leak into the caisson. If water accumulates in the caisson for a long time, it may penetrate into the floor slab at the bottom of the caisson. Utility Model Content

Through the air circulation between the air inlet 11 in the caisson and the secondary drainage pipe 12, the blockage of the secondary drainage pipe 12 caused by the vacuum generated in the caisson is prevented.
[0021] The four-way buffer connector 4 of this embodiment includes a connector body, a transverse pipe opening arranged on one side of the connector body, an upper pipe opening arranged on the upper part of the connector body, a lower pipe opening arranged on the lower part of the connector body, and a buffer extension pipe 1 that is horizontally closed and arranged opposite to the transverse pipe opening. The transverse pipe opening is connected to the drainage transverse pipe 3, the upper pipe opening is connected to the floor drain pipe 5, and the lower pipe opening is connected to the water trap 6. The buffer extension pipe 1 has a length of 150mm-400mm and a diameter of 50mm-110mm. The horizontally closed buffer extension pipe has a buffering function to prevent the floor drain from overflowing when the water is fully drained.
[0022] like Figure 2-3 As shown, the method for connecting the buffer extension tube 1 with the four-way buffer connector 4 includes: the buffer extension tube 1 and the connector body are integrally formed by injection molding through a mold.
[0023] The method for connecting the buffer extension pipe 1 with the four-way connector includes: the four-way buffer connector 4 is made by connecting the four-way connector and the separated buffer extension pipe 1. The buffer extension pipe 1 has an open end and a sealed end, and the open end of the buffer extension pipe 1 is connected to the connection pipe opening of the four-way connector facing the drainage horizontal pipe 3. The connection method can be as follows: Figure 4-5 As shown, the open end of the buffer extension tube 1 is connected to the connecting pipe opening of the cross-connector by means of sleeve-on and gluing or embedding-on and gluing. Figure 6 As shown, the open end of the buffer extension tube 1 is connected to the connecting pipe opening of the cross-connector by means of threads and gluing.
[0024] In this embodiment, the buffer extension tube 1 has a length of 150 mm to 400 mm and a diameter of 50 mm to 110 mm. For example, the buffer extension tube 1 has a length of 150 mm, 180 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm and a diameter of 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm.
[0025] The buffer extension pipe 1 is provided in this embodiment to receive and slow down the wastewater flow rushing from the drainage transverse pipe 3, avoiding the direct impact of the wastewater flow on the inner wall of the four-way buffer connector 4 to cause backflow, thereby ensuring the hygiene of the bathroom. Therefore, the drainage transverse pipe 3 can not only be connected to a drain, but also be provided with multiple oblique pipe ports, which are connected to the horizontal drainage branch pipe 8, and the horizontal drainage branch pipe 8 is set at an angle of 45 degrees to 135 degrees with the drainage transverse pipe 3, such as 45 degrees, 90 degrees, and 135 degrees.

[0026] Usually, the feces branch pipe 13 is provided with a separate sewage riser. When the original building has only one main drainage riser 7 that needs to be shared, the siphon principle can be fully utilized to make the feces discharge from the feces branch pipe 13 smoother, effectively separate the sewage and feces pipes, and at the same time, the secondary drainage pipe 12 can be lowered to the lowest point.
[0027] In this embodiment, the water trap 6 is used at the lower end of the floor drain in the wet area of the shower room, so that the sealing functions of multiple water traps required for multiple drainage points are concentrated in this water trap 6, reducing materials and workload.
[0028] Embodiment 2: Based on Embodiment 1, the inner wall of the buffer extension tube 1 can also be set to have several protruding triangular or trapezoidal spiral edges, which can serve as a reinforcing rib structure. The skeleton formed by it can respond quickly to the impact of water flow, and has higher strength and durability, so as to reduce the impact force of the water flow and slow down the water flow speed, while also reducing the noise in the pipeline.
[0029] The above embodiment is only one implementation of the utility model, but does not constitute a limitation. Any simple modification, change, substitution, combination, or simplification made without departing from the spirit of the utility model is equivalent to an equivalent replacement method and should be within the protection scope of the utility model.
