Description

Technical Field

[0001] The utility model relates to the field of building drainage, in particular to a fast-pass P-type water trap. Background Art

[0002] In building drainage systems, the P-trap is a water-sealed accessory installed inside sanitary fixtures or on the fixture drainage pipe section. It prevents odors from branch pipes from entering the room. While meeting a 50mm water seal, the P-trap results in a larger overall size. In drop-down drainage on the same floor, the caisson drop height is generally 350mm. After completing the caisson's lower leveling and waterproofing, the caisson's effective size is less than 300mm. Branch pipes are installed at a slope, and the P-trap is generally set at the starting end. This results in the upper water inlet extending beyond the finished decorative surface during installation, making it impossible to install a floor drain. When a bathroom has a dry area floor drain, a standard P-trap often fails due to evaporation of the water seal due to a lack of water replenishment, causing odors to return to the bathroom.

[0003] In the building's multi-layer drainage system, according to national standards, the net height of the bathroom should not be less than 2.2m. Therefore, after the installation of the drainage branch pipe, the bathroom ceiling height will generally be set above the top of the window or the ceiling height will not exceed 350mm. Generally, the bottom of the ordinary P-type water trap often exceeds the ceiling, making it impossible to construct the fine decoration. Utility Model Content

[0004] In order to solve the problem caused by the large size of the P-type water trap in the prior art, the utility model proposes a fast-pass P-type water trap.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] A fast-pass P-type water trap includes: a water inlet section, a funnel connecting section, a flow channel section and a water outlet section. One end of the flow channel section is upward, and the other end is toward one side, and the other end is higher than the one end. The cross-section of the flow channel section is set to be flat or elliptical. One end of the flow channel section has a sectioned vertical section. A funnel connecting section is set between one end of the flow channel section and the water inlet section, and a funnel connecting section is set between the other end of the flow channel section and the water outlet section.

[0007] Preferably, the cross-section of the flow channel section is U-shaped or V-shaped.

[0008] Preferably, the cross-sectional area of ​​the flow channel section is the same as the water inlet cross-sectional area of ​​the water inlet section and the water outlet cross-sectional area of ​​the water outlet section.

[0009] Preferably, a side pipe section for side water inlet may be provided on one side of the water inlet section above the flow channel pipe, and the diameter of the side pipe section is smaller than or equal to the diameter of the water outlet section.

[0010] Preferably, the diameter of one end of the funnel connecting section is the same as the diameter of the water inlet section or the water outlet section, and the cross-section of the other end is the same as the cross-section of the flow channel section.

[0011] The beneficial effects of the present invention are as follows: the water-passing cross-section of the flow channel section of the present invention is a flat or elliptical structure, and the interval between the inner middle top and the right bottom of the flow channel section is the water seal height. When the water seal height meets 50mm, the vertical height of the water seal channel can be directly reduced, the overall size can be reduced, and the problem caused by the large size of the P-type water trap can be solved. In addition, water flows through the water inlet section into the flow channel section and then flows out through the water outlet section. The water flows through the water inlet section and the funnel connecting section and gathers to the flow channel section. The water flow in the flow channel section spreads to the water outlet section through the funnel connecting section. The water flow of the fast-pass P-type water trap spreads at both ends and gathers in the middle, which accelerates the speed of water entering the flow channel section and the speed of water discharge from the flow channel section.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: Figures 1 to 3 The illustrated quick-pass P-trap comprises an inlet section 1, a funnel connection section 2, a flow channel section 3, and an outlet section 4. One end of the flow channel section 3 faces upward, while the other end faces to one side and is higher than the other end. The flow channel section 3 has an elliptical cross-section and a vertical section at one end. The funnel connection section 2 is provided between one end of the flow channel section 3 and the inlet section 1, and between the other end and the outlet section 4. The flow channel section has a U-shaped cross-section.

[0022] The cross section of the flow channel section can be set to be flat, with the front and rear sides being horizontal and the left and right sides being arc-shaped. The cross section of the flow channel section can also be set to be V-shaped.

[0023] The water seal height of the flow channel section is the distance H between the middle top and the bottom on the other side. Due to the elliptical or flat cross-section of the flow channel section, the vertical height of the water seal channel is reduced without changing the water seal height, thereby reducing the overall size.

[0024] As 1 to Figure 3 As shown, the cross-sectional area of ​​the flow channel section is identical to the inlet and outlet cross-sectional areas of the inlet and outlet sections. The diameter of one end of the funnel connection section is the same as that of the inlet or outlet section, while the cross-sectional area of ​​the other end is identical to that of the flow channel section. The inlet and outlet sections have the same diameter. The inlet and outlet flow rates of the quick-pass P-trap remain consistent.

[0025] Water flows through the cylindrical inlet section, into the elliptical flow channel section, and then out through the cylindrical outlet section. The water flow in the inlet and outlet sections diffuses, while the water flow in the flow channel section converges, accelerating the flow rate of water entering the flow channel section and the speed of water discharge from the flow channel section. The vertical section on the flow channel section can accelerate the convergence of water flow.

[0026] Example 2: Figure 4 The illustrated quick-release P-trap, based on Example 1, features a side pipe section 5 for side water inlet, located above the flow channel, on one side of the water inlet section 1. The diameter of this side pipe section 5 is smaller than or equal to the diameter of the water outlet section 4 and is parallel to the water outlet section, meeting the requirements of different sanitary fixtures and improving product adaptability. This side pipe section can serve as both a water inlet and a water replenishment port.

[0027] Example 3: Figure 5The illustrated quick-release P-trap, based on Example 1, features a side pipe section 5 for side water inlet, located above the flow channel, on one side of the water inlet section 1. The diameter of this side pipe section 5 is smaller than or equal to the diameter of the water outlet section 4 and is perpendicular to the water outlet section, meeting the requirements of different sanitary fixtures and improving product adaptability. This side pipe section can serve as both a water inlet and a water replenishment port.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
