Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of drainage systems, and in particular relates to a vertical pipe centralized water seal anti-odor drainage system with water replenishment function. BACKGROUND

[0002] In existing residential bathrooms, shower floor drains, washing machine floor drains, washbasin traps, and bathtub traps are all separately arranged. Once there is no water replenishment for a long time or the air pressure of the drainage network fluctuates, the water seal is prone to dry up and fail, causing the water seal of one or more appliances to be damaged. The damage of a water seal can lead to indoor odor.

[0003] There are two main methods for centralizing water seals in one place. One method is to completely separate the water seals from the vertical drainage pipe and collect them in one place, such as a drainage collector (CN118407493A, CN222936139U). The collector is then connected to the vertical drainage pipe through a pipe. This method requires a large space for the drainage collector, and the connection between the collector and the drainage pipe occupies a height, which is more commonly used for cross-layer drainage and less commonly used for same-layer drainage. The other method is to combine the vertical drainage pipe with the water seal. Although it is integrated, it is still two devices, and the vertical drainage pipe and the centralized water seal are connected through a connecting piece (CN212835700, CN111287263B). This method has the problem of occupying a large space. In addition to the opening of the vertical drainage pipe, a large-sized plate hole needs to be reserved on the floor, which is used to place the centralized water seal. This has a great impact on the space, layout, and pre-embedding of the bathroom. SUMMARY

[0004] In view of the above analysis, the embodiments of the present application aim to provide a vertical pipe centralized water seal anti-odor drainage system with water replenishment function to solve one or more of the above problems in the prior art.

[0005] The purpose of the present application is achieved as follows: A vertical pipe centralized water seal anti-odor drainage system with water replenishment function, comprising: a vertical drainage pipe; a drainage horizontal branch pipe having a horizontal straight pipe section and a winding section, the inlet end of the winding section being in communication with the outlet end of the horizontal straight pipe section, the winding section being wound downward and then upward along the outer periphery of the vertical drainage pipe, and the outlet end of the winding section being in communication with the vertical drainage pipe; the winding section has a water trap, and the centralized water seal formed after the water trap is filled with water has a water seal bottom point and a water seal top point; a water replenishment device for replenishing water to the water seal; wherein the inlet end of the drainage horizontal branch pipe is connected to the drainage ends of multiple water-using appliances through a branch pipe.

[0006] Further, a sleeve is provided, which is sleeved on the outside of the vertical drainage pipe and the winding section.

[0007] Furthermore, it also includes a water-stop joint, which is disposed on the outer wall of the sleeve.

[0008] Furthermore, a water-stop joint is provided every 30cm along the axial direction of the sleeve.

[0009] Furthermore, the water-stop joint at the top of the sleeve is flush with the floor slab, and the bottom end of the sleeve is fixedly connected to the wall by a bracket.

[0010] Furthermore, the outlet end of the winding section is a connecting port, which is located on the pipe wall of the drainage riser. The winding section is integrally formed with the drainage riser.

[0011] Furthermore, the water replenishment device has a pipe body, the two axial ends of which are connected to the horizontal pipe section; an inspection port is provided on the side wall of the pipe body, and an inspection cover plate that can be opened and closed is provided on the inspection port; Furthermore, the inspection cover is provided with a water supply pipe interface, which is connected to a water supply pipe.

[0012] Furthermore, the water supply pipe interface extends 2cm above the top surface of the inspection cover. Furthermore, the diameter of the inspection port is 50mm.

[0013] Furthermore, the water supply pipe is equipped with a solenoid valve.

[0014] Furthermore, the water supply pipe is also equipped with an anti-backflow device.

[0015] Furthermore, the winding segment is wound around the drainage riser in a rounded bend manner.

[0016] Furthermore, the diameter of the drainage riser is De110 or De160; the diameter of the drainage horizontal branch pipe is De50 and De75.

[0017] Furthermore, the height H of the water seal is not less than 50 mm.

[0018] Compared with the prior art, the riser centralized water seal odor prevention and drainage system with water replenishment function provided by the present invention has the following beneficial effects: 1. The water seals of various sanitary ware and floor drains can be centrally installed, making the arrangement of sanitary ware and floor drains more flexible. Under the common building foundation conditions of 90-130mm, and on the premise of ensuring a slope of 0.026 for the drainage horizontal branch pipe, the same-floor drainage in the conventional foundation can be realized. This more effectively avoids the problem of back odor in the entire bathroom caused by the failure of a water seal or the drying of the water seal due to long-term disuse. With automatic water replenishment, the problem of back odor caused by the failure of the water seal can be solved to the greatest extent.

[0019] 2. The drainage horizontal branch pipe naturally forms a centralized water seal by winding with the drainage riser. Only the hole of the conventional drainage riser needs to be enlarged, and there is no need to leave a hole in the structural slab. Attached Figure Description

[0026] Example 1 A specific embodiment of the present invention discloses a riser centralized water seal anti-odor drainage system with water replenishment function, such as... Figures 1 to 14As shown, the system includes a drainage riser 1, a drainage horizontal branch pipe 2, and a water replenishment device. The drainage horizontal branch pipe 2 has a horizontal straight pipe section 21 and a winding section 22. The inlet end of the winding section 22 is connected to the outlet end of the horizontal straight pipe section 21. The outlet end of the winding section 22 winds downwards and then upwards along the outer circumference of the drainage riser 1. The outlet end of the winding section 22 is connected to an interface on the drainage riser 1. The winding section 22 has a water trap 25. The water seal formed after the water trap 25 is filled with water has a water seal bottom point 23 and a water seal apex 24. The water seal formed here is a centralized water seal, and the height H of the water seal is not less than 50mm. The inlet end of the drainage horizontal branch pipe 2 is connected to the drainage end of multiple water appliances through a branch pipe. The water replenishment device is used to replenish water to the water seal.

[0027] In this embodiment, the riser centralized water seal odor prevention and drainage system with water replenishment function also includes a sleeve 3. The sleeve 3 is a circular sleeve, which is sleeved on the outside of the drainage riser and the winding section 22. That is to say, the circular sleeve is set on the outside of the drainage riser and the winding drainage horizontal branch pipe to ensure the integrity of the pipe fittings, while also supporting the winding pipe and integrating the water-stop joint.

[0028] For example, Figure 10 Figures a, b, c, d, and e illustrate the process of the horizontal branch pipe being wound around the drainage riser. The figures show the spatial relationship between the horizontal straight pipe section 21, the wound section 22, and the drainage riser 1. The sleeve is not shown in this figure. The wound section 22 is wound around the drainage riser 1 with rounded corners. The distance from the bottom of the horizontal straight pipe section connecting to the indoor drainage branch pipe to the top of the sleeve 3 is 20mm. Figure 10 In Figure a, the orange section represents the horizontal straight pipe segment, which bends downwards with rounded corners (as shown in Figure a). Figure 10 (As shown in the orange part of Figure b), from the drain horizontal branch pipe entering the sleeve 3, it bends downwards in a clockwise direction and wraps around the drain riser to the water seal bottom point 23 (as shown in Figure b). Figure 10 The lower end of the orange section shown in Figure C is the water seal bottom point. Then, starting from the water seal bottom point 23 of the drainage horizontal branch pipe, bend and wrap the drainage riser pipe upwards in a clockwise direction (as shown in Figure C). Figure 10 (As shown in the orange section of diagram d) reaches the water seal apex 24, ensuring the water seal height is not less than 50mm; continue bending and winding (as shown in the diagram d). Figure 10 (The orange part shown in Figure e) is connected to the drainage riser 1.

[0029] In this embodiment, the riser centralized water seal anti-odor drainage system with water replenishment function also includes a water-stop joint 5, which is disposed on the outer wall of the sleeve 3. In one optional embodiment, a water-stop joint 5 is installed every 30cm along the axial direction of the sleeve 3, laid inside the structural slab, which can prevent water leakage when combined with the floor slab during pouring. The water-stop joint 5 at the top of the sleeve 3 is flush with the floor slab, and the bottom end of the sleeve 3 is fixedly connected to the wall by a bracket.

[0030] In this embodiment, the winding section 22 is integrally formed with the drainage riser 1. The connecting port 4 is the interface on the drainage riser after the drainage horizontal branch pipe is wound. It can also be understood that the outlet end of the winding section 22 is the connecting port 4. The connecting port 4 is located on the pipe wall of the drainage riser 1. The drainage horizontal straight pipe 2 is connected to the water supply device and the indoor horizontal branch pipe. The drainage riser is connected to the drainage risers of the upper and lower floors.

[0031] In this embodiment, the water replenishment device integrates an inspection port and a water replenishment pipe interface, enabling it to function not only for replenishing water but also for maintenance. Specifically, by connecting the water replenishment device to the horizontal and vertical pipe section 21, the centralized water seal can be cleaned and maintained, and water can be replenished to the water seal periodically. In other words, the inspection port and the pipe are combined into a single fitting, and the inspection port can be opened through an inspection cover for pipe cleaning and maintenance.

[0032] In one alternative embodiment, the water replenishment device has a pipe body, the two axial ends of which are connected to the horizontal pipe section 21; an inspection port is provided on the side wall of the pipe body, and an inspection cover 7 that can be opened and closed is provided on the inspection port. The inspection cover 7 can be detachably installed at the pipe wall installation port of the horizontal pipe section 21. Preferably, the inspection cover 7 is provided with a water supply pipe interface 6, which is connected to a water supply pipe 8. The water supply pipe 8 is connected to a water source, and water is supplied to the water seal through the water supply pipe 8. Further, the water supply pipe interface 6 is 2cm above the top surface of the inspection cover; the diameter of the inspection port is 50mm.

[0033] In this embodiment, the water replenishment device is an electrically controlled water replenishment device, which uses electric control to achieve intelligent water replenishment to the centralized water seal. Specifically, one end of the water replenishment pipe 8 is connected to a water source, and the other end is connected to the water replenishment pipe interface 6. The water replenishment pipe 8 can be a DN10 flexible hose, and a solenoid valve 9 is provided on the water replenishment pipe 8. This embodiment can adopt a timed water replenishment method. According to the set time, the solenoid valve is opened, and water flows through the water replenishment pipe to replenish the water seal. When the set time is reached, the solenoid valve is closed. To prevent water seal and sewage backflow into water supply pipe 8, an anti-backflow device 10 is also provided on water supply pipe 8. The function of the anti-backflow device 10 is to allow water in water supply pipe 8 to flow unidirectionally into water seal. The anti-backflow device 10 can be understood as a one-way valve, which can be achieved using existing technology.

[0034] In this embodiment, the diameter of the drainage riser 1 is De110 or De160; the upper end of the drainage riser 1 extends 100mm beyond the top surface of the sleeve, and the lower end extends 30mm beyond the bottom surface of the sleeve.

[0035] In this embodiment, the diameter of the drainage horizontal branch pipe 2 is De50 and De75. The reserved interface of the horizontal and straight pipe section 21 of the drainage horizontal branch pipe is connected to other sanitary ware and floor drains in the house except for the toilet. The distance between the bottom of the horizontal and straight pipe section 21 of the drainage horizontal branch pipe and the top of the sleeve 3 is 20mm.

[0036] In this embodiment, the various pipe fittings used in the riser centralized water seal odor prevention and drainage system with water replenishment function are made of plastic pipes such as PVC, UPVC, and HDPE.

[0037] Depending on the requirements, the riser centralized water seal odor prevention and drainage system with water replenishment function can be divided into two models: Type 75 and Type 50. Among them, the dimensions of the Type 75 sleeve 3 are 322mm in diameter and 359mm in height; the dimensions of the Type 50 sleeve 3 are 272mm in diameter and 284mm in height.

[0038] In this embodiment, the riser centralized water seal odor prevention and drainage system with water replenishment function can be constructed using either of the following two methods: The first construction scheme involves placing the centralized water seal anti-odor drainage system with water replenishment function directly in the designed position during the floor slab pouring, integrating the system with the floor slab. The water-stop joint extends into the floor slab, resulting in good overall integrity. The top water-stop joint of sleeve 3 is flush with the floor slab. The second construction scheme involves pouring the floor slab first, reserving holes for the drainage risers with a hole size of 300mm. After the pipe fittings arrive at the construction site, they are installed in the reserved holes according to the designed position. The top water-stop joint of sleeve 3 is flush with the floor slab, and the bottom of sleeve 3 is fixed to the wall with a bracket.

[0039] Compared with the prior art, the riser centralized water seal odor prevention and drainage system with water replenishment function provided in this embodiment has the following beneficial effects: 1. The present invention relates to a centralized water seal anti-odor drainage system with water replenishment function, wherein the winding section of the horizontal branch pipe connecting the indoor drainage pipe is tightly wound with the drainage riser. The winding section of the horizontal branch pipe naturally forms the water seal height through winding, and the water seal section is spatially located within the floor slab. There is no need to set up a separate centralized water seal device outside the drainage riser. The water seal and the drainage riser tee fitting are integrated to form a new type of centralized water seal anti-odor drainage system. It is also equipped with a water replenishment device with an inspection port and a water replenishment pipe interface. By installing a solenoid valve and an anti-backflow device on the water replenishment pipe, a centralized water seal anti-odor drainage system with automatic water replenishment function is formed.

[0040] 2. The centralized water seal anti-odor drainage system with water replenishment function of this invention eliminates the need for separate water seals for sanitary ware or floor drains, achieving centralized water seals. It also includes a pre-installed water replenishment pipe interface, solving the problem of insufficient drainage slope caused by dispersed water seals occupying height in same-floor drainage, addressing the issue of water seals drying out and failing due to prolonged vacancy of individual sanitary ware or floor drains, and resolving indoor odor backflow. Even if the centralized water seal dries out due to prolonged vacancy, it can be replenished automatically. This invention effectively reduces the space occupied by water seal pipes, minimizing the impact on bathroom space, layout, and pre-installed infrastructure.

[0041] Example 2 Another specific embodiment of the present invention discloses a different type of riser centralized water seal odor prevention and drainage system with water replenishment function, such as... Figures 15 to 23 As shown, the difference from Example 1 lies in the water replenishment method. Specifically, the water replenishment device used in this example is a drainage water seal mechanical water replenishment device, while the water replenishment device in Example 1 is an electrically controlled water replenishment device.

[0042] See Figures 15 to 23 The drainage water seal mechanical water replenishment device of this embodiment includes a water tank 11.10, a water replenishment pipe 11.2, and a sealing device. The water tank 11.10 can be cylindrical. The water replenishment pipe 11.2 has an inlet and an outlet. The outlet is located in the top space of the water tank 11.10, and the inlet is located outside the water tank 11.10 and connected to an indoor water replenishment pipe. The sealing device is configured to seal and open the outlet. The sealing device has a water replenishment sealing cover 11.3 and a lever drive mechanism. The water replenishment sealing cover 11.3 is located at the outlet. One end of the lever drive mechanism is connected to the water replenishment sealing cover 11.3. The other end of the lever drive mechanism floats in the water in the water tank; the liquid level in the water tank is level with the liquid level of the centralized water seal, and the lever drive mechanism achieves the water supply sealing cover 11.3 covering or opening the outlet of the water supply pipe 11.2 by changing the water level in the water tank 11.10; the bottom of the water tank 11.10 is provided with a water supply connection interface 11.1, which is connected to the centralized water seal; optionally, the water tank 11.10 includes two threaded parts, specifically an upper half and a lower half, which are connected by threads, and a sealing ring 11.8 is provided at the connection between the upper half and the lower half.

[0043] In this embodiment, a centralized water seal is formed inside the water trap 25, and a centralized water seal connection interface 12 is provided on the side wall of the water trap 25. The water replenishment connection interface 11.1 is connected to the centralized water seal connection interface 12.

[0044] In this embodiment, the water supply connection interface 11.1 and the centralized water seal connection interface 12 can be plugged in, threaded, or other connection methods. Threaded connection is preferred. For example, the centralized water seal connection interface 12 has an internal thread, and the water supply connection interface 11.1 has an external thread; the two interfaces are connected by threads. The centralized water seal connection interface 12 and the water supply connection interface 11.1 are made of the same material, such as PVC or HDPE.

[0045] In one alternative embodiment, the outlet of the water supply pipe 11.2 is arranged facing upwards, and the water supply sealing cover 11.3 is placed over the outlet. The lever drive mechanism has a lever 11.4 and a float valve 11.7. The lever fulcrum 11.5 of the lever 11.4 is suspended and fixed to the lower surface of the top cover 11.9 by a fulcrum fixing member 11.6. The float valve 11.7 floats in the water in the water tank and is connected to one end of the lever 11.4. The other end of the lever 11.4 is connected to the water supply sealing cover 11.3. The water supply sealing cover 11.3 is opened and closed by the up and down movement of the float valve 11.7. In other words, the water supply pipe 11.2 has a U-shaped structure with its two ends at different heights. The two ends of the water supply pipe 11.2 are the inlet and the outlet, respectively. The inlet of the water supply pipe 11.2 is higher than the outlet. The upper inlet connects to the indoor water supply pipe, and the lower outlet is equipped with a water supply sealing cap 11.3. The water supply sealing cap 11.3 is connected to a lever drive mechanism. The lever drive mechanism controls the water level in the water tank 11.10 to open or close the water supply sealing cap 11.3 at the outlet of the water supply pipe 11.2. Normally, the outlet of the water supply pipe 11.2 is sealed by the water supply sealing cap 11.3. When the water supply sealing cap 11.3 is opened, water is supplied to the water tank 11.10 through the outlet, and then to the water seal through the water supply connection interface 11.1 at the bottom of the water tank 11.10. The lever 11.4 is roughly parabolic or inverted √ shape. The fulcrum 11.5 of the lever 11.4 is located at the vertex of the parabola or the inflection point of the inverted √ shape. The lever 11.4 is divided into two parts, a first segment and a second segment, at the fulcrum 11.5. The water supply sealing cap 11.3 is connected to the end of the first segment, and the float valve 11.7 is connected to the end of the second segment. The length of the first segment is shorter than the length of the second segment. Both the first segment and the second segment can be arc-shaped, and both can be composed of a combination of straight segments and arc-shaped segments.

[0046] In this embodiment, the top of the water tank 11.10 is also provided with a top cover 11.9. The top cover 11.9 is provided with a pipe penetration opening 11.92 and a water supply vent 11.93. The pipe penetration opening 11.92 is for the water supply pipe 11.2 to pass through, and the water supply vent 11.93 is used to balance the air pressure inside and outside the water tank. The water supply pipe 11.2 passes through the pipe penetration opening 11.92 of the top cover 11.9 and exits the top surface of the mechanical water supply device 11, connecting to the indoor water supply pipe; the outlet of the water supply pipe 11.2 enters the water tank 11.10 of the mechanical water supply device 11 through the pipe penetration opening 11.92; the water supply vent 11.93 serves to balance the air pressure.

[0047] Furthermore, the top cover 11.9 is also provided with a cross rib 11.91. The function of the cross rib 11.91 is to connect the water supply connection interface 11.1 of the mechanical water supply device 11 and the centralized water seal connection interface 12 together by rotating the cross rib 11.91.

[0048] In this embodiment, the centralized water seal connection interface 12 is located at the bottom of the centralized water seal, and between the bottom point 23 and the top point 24 of the water seal. Preferably, the centralized water seal connection interface 12 is at least 10 mm higher than the bottom point 23 of the water seal.

[0049] During implementation, the lower part of the mechanical water supply device 11 enters the interior of the sleeve 3 through the reserved hole on the top surface of the sleeve 3, and is connected to the centralized water seal connection interface 12 at the bottom of the water trap 25 by means of threads. The water supply pipe 11.2 passes through the pipe penetration reserved port 11.92 of the top cover 11.9 of the water tank 11.9 and exits the top surface of the mechanical water supply device 11, connecting to the indoor water supply pipe. When the water seal height is normal, the liquid level in the water tank is level with the centralized water seal liquid level. When the water seal liquid level of the centralized water seal drops, the float valve 11.7 drops, the water supply sealing cover 11.3 opens, and tap water enters the water tank 11.10 through the water supply pipe 11.2, raising the water level in the water tank 11.10 and replenishing the water seal through the water supply connection interface 11.1, causing the water seal liquid level to rise. When the normal water seal height is reached, the float valve 11.7 rises, and the linked water supply sealing cover 11.3 closes, stopping the water inlet.

[0050] Compared with the prior art, the riser centralized water seal odor prevention and drainage system with water replenishment function provided in this embodiment, in addition to having the same beneficial effects as Embodiment 1, also has the following beneficial effects: 1. It can automatically replenish water to water seals or centralized water seals without the need for electrical control, eliminating the need for an electrical control system, resulting in low cost and high reliability.

[0051] 2. Since no additional electrical control system is required, the impact on existing buildings is minimal.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
