Description

Technical Field

[0001] The present application relates to the technical field of building drainage, and in particular to a non-clogging and odor-free heated water trap and an application method thereof. Background Art

[0002] The anti-blocking trap is a component of the building drainage system and is mainly used in the drainage pipes of sanitary equipment such as wash basins, bathtubs, shower rooms, floor drains, etc. It is a device that prevents sewer gas from flowing back into the room.

[0003] The trap under the kitchen sink is prone to clogging due to the accumulation of grease and other impurities after long-term use. The industry typically adopts two main approaches to address this problem. One relies on chemical dissolution, using chemical detergents to dissolve the accumulated grease and impurities. This method is relatively simple to operate, requiring only the detergent to be poured into the trap. The other is mechanical unclogging, using specialized unclogging tools, such as pipe cleaners, to physically remove the blockage. Furthermore, an improved anti-clogging solution uses electric heating. This uses an external power source to heat the trap, preventing the grease from solidifying and thus alleviating the blockage.

[0004] Chemical dissolution methods are not only costly and inefficient, but the use of chemical cleaning agents can also pollute the environment. Mechanical dredging also faces the challenges of high cost and low efficiency, and may cause some damage to the pipe. While electric heating declogging solutions can alleviate blockages to a certain extent, they require an external power supply, which undoubtedly increases energy consumption. These methods have significant shortcomings in terms of energy efficiency and universal applicability. Summary of the Invention

[0005] In order to improve the energy saving and universality of the water trap, the present application provides a blocking-free and odor-free heating water trap and an application method thereof.

[0006] On the one hand, the present application provides a non-blocking and odor-free heating water trap, which adopts the following technical solutions: A non-clogging and odor-free heating water trap, comprising: The trap body includes a water inlet pipe section, a drainage pipe section, and a trap pipe connected between the water inlet pipe section and the drainage pipe section. The trap pipe is located below the water inlet pipe section and the drainage pipe section. The trap pipe includes a curved pipe section and straight pipe sections connected to both ends of the curved pipe section. The straight pipe section is connected to an oil discharge interface. A heating device comprising a heat exchange tube, the heat exchange tube being arranged around the outside of the water trap and being connected to a heat source; An oil collecting tank is connected to an oil collecting pipe and an oil drain pipe, the oil collecting pipe is connected to the oil drain port, a first flow control member is provided on the oil collecting pipe, and the first flow control member is used to control the opening and closing of the oil collecting pipe and the directly connected pipe section, and the oil drain pipe can be opened and closed and is provided at the bottom of the oil collecting tank; The liquid level adjustment component includes a first liquid level detector, a liquid boosting tube and a second flow control component arranged on the liquid boosting tube, the liquid boosting tube is connected to the curved pipe section, and the second flow control component is used to control the connection and disconnection of the liquid boosting tube and the curved pipe section; and the first flow control component and the second flow control component are both electrically connected to the first liquid level detector.

[0007] By adopting the above technical solution, the heat exchange pipe of the heating device is arranged outside the water trap and connected to a heat source. The heat source can be an existing heat source such as a shower hot water pipe or floor heating pipe. The heat exchange pipe is connected to the shower hot water pipe. When the shower hot water pipe is transporting hot water, it can provide hot water to the water trap to continuously soften or melt grease, preventing grease solidification and accumulation in the water trap, thereby preventing clogging. At the same time, the high temperature inhibits the growth of anaerobic bacteria and reduces odor. When grease accumulates in the water trap, water is added to the water trap through the liquid increase pipe to raise the liquid level in the water trap to a preset level. The first flow control element is then activated to allow the grease floating on the surface to be discharged from the oil discharge interface along the oil collection pipe into the oil collection tank. The second flow control element controls the opening and closing of the liquid increase pipe and the pipe section based on the liquid level detected by the first liquid level detector. When the liquid level rises to the preset level, the addition of water to the water trap is stopped to prevent excessive water from being added during oil discharge and causing excessive water to enter the oil collection tank.

[0008] Optionally, an oil-water separation tank is provided in the oil collecting tank, and one end of the oil collecting pipe is connected to the oil-water separation tank; A guide plate is provided in the oil-water separation tank. The guide plate is located at the connection point between the oil receiving pipe and the oil-water separation tank, and the guide plate is tilted downward in a direction away from the oil receiving pipe.

[0009] By adopting the above technical solution, the mixture of grease and oil collected by the water trap body enters the oil-water separation tank in the oil collecting tank through the oil discharge interface and the oil collection pipe. The guide plate can guide the mixture to flow away from the liquid surface, slowing down the flow rate of the liquid entering the oil-water separation tank, preventing the newly entered oil-water mixture from disturbing the separated oil layer, and achieving a better oil-water separation effect.

[0010] Optionally, the bottom of the oil-water separation tank is connected to a drain pipe, and one end of the drain pipe passes through the oil collecting tank, and a third flow control member is provided on the drain pipe; The oil-water separation tank is provided with a second liquid level detector, and the second liquid level detector is electrically connected to the third flow control component.

[0011] By adopting the above technical solution, a drain pipe connected to and passing through the oil collecting tank is set at the bottom of the oil-water separation tank and a third flow control component is installed. In combination with the second liquid level detector and the third flow control component, the drain pipe can be automatically controlled to be open and closed according to the liquid level in the oil-water separation tank to discharge the separated water. The drainage volume can also be controlled so that the water in the oil-water separation tank cannot be completely drained during discharge, thereby preventing the oil in the oil-water separation tank from being discharged along the drain pipe along with the water.

[0012] Optionally, the oil collecting tank is provided with a heat exchange shell, the heat exchange shell is connected to a heat supply inlet pipe and a heat supply outlet pipe, the heat supply inlet pipe is connected to one end of the heat exchange pipe, and the heat supply outlet pipe is connected to the other end of the heat exchange pipe; The heat supply inlet pipe is provided with a fourth flow control member, and the fourth flow control member is used to control the connection and disconnection of the heat supply inlet pipe and the heat exchange pipe; The heat supply inlet pipe is provided with a fifth flow control component, and the fifth flow control component is used to control the connection and disconnection of the heat supply exhaust pipe and the heat exchange pipe.

[0013] By adopting the above technical solution, the heat exchange shell is installed outside the oil collection tank and is connected to the heat exchange tubes through the heat supply inlet pipe and the heat supply outlet pipe. The fourth flow control element controls the opening and closing of the heat supply inlet pipe and the heat exchange tube to achieve temperature regulation of the oil collection tank. When the oil in the oil collection tank needs to be discharged, the fourth and fifth flow control elements are opened to allow the hot water in the heat exchange tubes to flow into the heat exchange shell, thereby heating the oil collection tank and smoothly discharging the oil in the oil collection tank. After the oil in the oil collection tank is discharged, the fourth and fifth flow control elements are closed, and the oil collection tank is no longer heated.

[0014] Optionally, a plurality of annular partitions are provided between the heat exchange shell and the oil collecting tank, and the annular partitions are provided with flow gaps, and the flow gaps of adjacent annular partitions are staggered; A heat exchange channel is formed between the plurality of annular partitions, the inner side wall of the heat exchange shell and the outer side wall of the oil collecting tank. One end of the heat exchange channel is connected to the heat supply inlet pipe, and the other end is connected to the heat supply exhaust pipe.

[0015] By adopting the above technical solution, the heat exchange flow channel is formed by multiple annular partitions and the inner wall of the heat exchange shell, and the flow gaps of adjacent partitions are staggered, which extends the flow path of the heating medium in the heat exchange shell, enhances the heat exchange effect between the oil collecting tank and the heating medium, and better maintains the temperature in the oil collecting tank above the melting point of the oil.

[0016] Optionally, the bottom of the curved pipe section is connected to a sewage valve.

[0017] By adopting the above technical solution, the remaining impurities deposited at the bottom of the bend section can be regularly cleaned through the drain valve, further reducing the probability of clogging of the water trap body.

[0018] Optionally, an end of the water inlet pipe section away from the water trap is detachably connected to a filter plate.

[0019] By adopting the above technical solution, the water inlet pipe section of the trap body away from the end of the trap pipe can be detachably connected to the filter plate, which can intercept large particles of impurities in the water and prevent them from entering the trap and causing blockage; at the same time, the detachable connection method facilitates the cleaning and replacement of the filter plate, which is beneficial to the maintenance of the trap body.

[0020] Optionally, a mounting ring is fixed in the water inlet pipe section, and the filter plate includes a connecting ring and a filter screen fixed in the connecting ring; An elastic inserting strip is fixed on one side of the connecting ring. One end of the elastic inserting strip gradually increases in size toward the connecting ring. An inserting port for the elastic inserting strip to pass through is provided on the mounting ring.

[0021] By adopting the above technical solution, the water inlet pipe section of the trap body is installed with a filter plate with a filter screen, which can intercept large particles of impurities in the drainage and prevent them from entering the trap and causing blockage; the cooperation between the elastic insert and the plug interface makes the filter plate detachable and connected to the water inlet pipe section, which is convenient for cleaning or replacement of the filter plate.

[0022] Optionally, an adhesive layer is provided between the heat exchange tube and the water trap, and the adhesive layer is made of a heat-conducting material.

[0023] By adopting the above technical solution, the heat exchange tube and the water trap are connected by an adhesive layer. The adhesive layer uses a heat-conducting material, which can more efficiently transfer the heat energy of the heat source in the heat exchange tube to the water trap.

[0024] On the other hand, the present application provides a non-clogging and odor-free heated water trap, which is used for drainage.

[0025] By adopting the above technical solution, the heat source can be used to heat the water trap pipe through the heat exchange tube, so that the heat energy can continuously soften or melt the grease, avoid solid accumulation and reduce maintenance costs. The first liquid level detector and the liquid level adjustment component can be used to ensure the stability of the liquid level in the water trap; the oil collecting tank and the oil-water separation tank can collect and separate the grease. The entire device is easy to install and maintain, and is suitable for a variety of building drainage systems.

[0026] In summary, this application has at least one of the following beneficial effects: 1. This application uses a heat exchange tube wrapped around the outside of the water trap and connected to a heat source, using heat energy to continuously soften and melt grease, preventing grease solidification and accumulation. The existing heat source is used to heat the water trap, eliminating the need for an external power supply, reducing energy consumption, installation complexity, and maintenance costs. 2.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] Example 1: The embodiments of the present application provide a blocking-free and odor-free heating water trap.

[0030] Reference Figure 1Embodiment 1: The blockage-free and odor-free heated water trap provided in the embodiment of the present application includes a water trap body 1 and a heating device 2. Specifically, the water trap body 1 includes an inlet pipe section 11, a drain pipe section 12, and a water trap pipe 13 connected between the inlet pipe section 11 and the drain pipe section 12. The inlet pipe section 11 is used to connect to drainage equipment, such as a kitchen sink, etc.; the drain pipe section 12 is connected to the sewer. The water trap pipe 13 is located below the inlet pipe section 11 and the drain pipe section 12, so that the water forms a certain water level in the water trap pipe 13, thereby blocking odors and harmful gases from the sewer. The water trap pipe 13 includes a curved pipe section 131 and a straight pipe section 132 connected to both ends of the curved pipe section 131. The curved pipe section 131 is specifically configured as a U-shaped tube, and the straight pipe section 132 is configured in a vertical state. The bottom of the curved pipe section 131 is connected to a drain valve 7 through a flange for directly discharging solid impurities deposited at the bottom of the curved pipe section 131.

[0031] Reference Figure 1 The heating device 2 includes a heat exchange tube 21, which is wound around the outside of the water trap 13; in other embodiments, the heat exchange tube 21 can also be surrounded by multiple layers of parallel tape around the outside of the water trap 13. An adhesive layer (not shown in the figure) is connected between the outer walls of the heat exchange tube 21 and the outer walls of the water trap 13, and the adhesive layer fixes the heat exchange tube 21 to the outside of the water trap 13. In order to achieve good heat exchange, the adhesive layer is made of a heat-conducting material. The heat exchange tube 21 is connected to a heat source 22, and the heat source 22 can be an existing heat source 22 such as a shower hot water pipe or a floor heating pipe. This embodiment takes a shower hot water pipe as an example. During actual use, the heat exchange tube 21 is connected to the pipe section of the shower hot water pipe. When the shower hot water pipe transports hot water, the hot water flows in the heat exchange tube 21, which can provide heat to the water trap 13, continuously softening or melting grease, and avoiding the solidification and accumulation of grease in the water trap 13.

[0032] Reference Figure 2 A mounting ring 14 is provided at one end of the water inlet pipe section 11 away from the water trap 13. The mounting ring 14 is fixed to the inner side wall of the water inlet pipe section 11, and a filter plate 8 is provided above the mounting ring 14. The filter plate 8 includes a connecting ring 81 and a filter screen 82 fixed on the inner side wall of the connecting ring 81. An elastic insert 83 is fixed to one side of the connecting ring 81. One end of the elastic insert 83 gradually increases in size toward the connecting ring 81, forming a truncated cone-shaped enlarged head 831. A plurality of elastic inserts 83 are fixed at intervals around the axis of the connecting ring 81. A plurality of plug ports 141 are provided on the mounting ring 14. The plug ports 141 are arranged one-to-one corresponding to the elastic inserts 83. The enlarged head 831 of the elastic insert 83 passes through the plug port 141 to realize the detachable connection of the filter plate 8 in the water inlet pipe section 11.

[0033] The trap body 1 can be made of hard plastic or metal material, which has good corrosion resistance and strength.

[0034] The implementation principle of this embodiment is: the heat exchange tube 21 is wound around the outside of the water trap 13 and connected to the heat source 22, and the heat of the existing heat source 22 is used to heat the water trap 13, avoiding the external power supply and additional circuit system required by the electric heating method, reducing installation complexity and maintenance costs, and reducing energy consumption.

[0035] Example 2 The blockage-free, odor-free heated water trap provided in this embodiment differs from that in Example 1 in that it is further provided with an oil collection tank 3 and a liquid level adjustment assembly 4. Furthermore, each directly connected pipe segment 132 is connected to an oil drain port 133, which can be connected to the directly connected pipe segment 132 by welding or threading.

[0036] Reference Figure 3 and Figure 4 The oil collecting tank 3 is connected to an oil collecting pipe 31 and an oil drain pipe 32. In this embodiment, both straight-connected pipe sections 132 are connected to an oil drain port 133. One end of the oil collecting pipe 31 is connected to two oil collecting branch pipes; each oil collecting branch pipe corresponds to and is in communication with the oil drain port 133. A first flow control component 33 is installed on the oil collecting pipe 31, and an opening and closing component is installed on the oil drain pipe 32. Rubber or plastic tubes can be used for the oil collecting pipe 31 and the oil drain pipe 32 for ease of connection and installation. The first flow control component 33 is specifically configured as a solenoid valve. When the first flow control component 33 is opened, the oil in the trap pipe 13 can flow into the oil collecting tank 3 through the oil drain port 133 and the oil collecting pipe 31. The opening and closing component can be a manual or automatic valve to open and close the oil drain pipe 32, facilitating regular discharge of oil from the oil collecting tank 3. In actual use, the oil collecting tank 3 needs to be installed below the trap body 1.

[0037] Reference Figure 3 The liquid level adjustment assembly 4 includes a first liquid level detector 41, a liquid boosting tube 42, and a second flow control member 43 disposed on the liquid boosting tube 42. The liquid boosting tube 42 is connected to the curved pipe section 131. One end of the first liquid level detector 41 is fixed within the curved pipe section 131, and the first flow control member 33 and the second flow control member 43 are both electrically connected to the first liquid level detector 41. The first liquid level detector 41 can be a liquid level sensor, which is used to detect whether the liquid level in the water trap 13 has risen to a preset value after water is boosted. The liquid boosting tube 42 can be connected to a water source, such as a tap water pipe. The second flow control member 43 is specifically a solenoid valve.

[0038] Reference Figure 4 and Figure 5An oil-water separation tank 5 is also fixed within the oil collecting tank 3. One end of the oil receiving pipe 31 is connected to the oil-water separation tank 5. A deflector 51 is installed within the oil-water separation tank 5. Located at the junction of the oil receiving pipe 31 and the oil-water separation tank 5, the deflector 51 is tilted downward, away from the oil receiving pipe 31. The deflector 51 can be a curved plate or a plate with a certain curvature. It guides the mixed liquid entering the oil-water separation tank 5 downward, preventing it from disturbing the already separated oil layer above the deflector 51 during liquid inflow.

[0039] A drain pipe 52 is connected to the bottom of the oil-water separation tank 5, and one end of the drain pipe 52 extends out of the oil collecting tank 3. A third flow control component 53 is installed on the drain pipe 52. A second liquid level detector 54, which is a liquid level sensor, is fixed to the bottom of the oil-water separation tank 5. The second liquid level detector 54 is electrically connected to the third flow control component 53. The drain pipe 52 is typically made of plastic or metal to ensure smooth drainage. The third flow control component 53 is a solenoid valve that automatically controls drainage based on the liquid level detected by the second liquid level detector 54. When the oil collection pipe 31 continuously drains the oil-water separation tank 5 until the second liquid level detector 54 detects that the liquid level in the oil-water separation tank 5 is approaching the tank opening, the second liquid level detector 54 sends a signal to the third flow control component 53, opening it and draining a certain amount of water from the oil-water separation tank 5 through the drain pipe 52, allowing the next oil-water mixture in the oil collection pipe 31 to enter.

[0040] When the second liquid level detector 54 detects that the liquid level in the oil-water separation tank 5 has dropped to a preset level, the third flow control element 53 is controlled to close. During this process, the primary discharge volume from the oil-water separation tank 5 must be kept slightly lower than the primary inflow volume into the oil collection pipe 31. This ensures that once the liquid in the oil-water separation tank 5 has accumulated to a certain level, the primary inflow volume into the oil collection pipe 31 can raise the liquid level in the oil-water separation tank 5 above the tank opening, allowing some of the separated oil to be discharged into the oil collection tank 3.

[0041] Reference Figure 4 and Figure 5 The oil collecting tank 3 is covered with a heat exchange shell 6. A plurality of annular baffles 65 are vertically spaced between the heat exchange shell 6 and the oil collecting tank 3. Each annular baffle 65 has a flow gap 651. The flow gaps 651 of adjacent annular baffles 65 are staggered. A heat exchange channel 66 is formed between the plurality of annular baffles 65, the inner wall of the heat exchange shell 6 and the outer wall of the oil collecting tank 3. Figure 1 and Figure 4 One end of the heat exchange channel 66 is connected to the heat supply inlet pipe 61, and the other end of the heat exchange channel 66 is connected to the heat supply inlet pipe 61. The heat supply inlet pipe 61 is connected to one end of the heat exchange tube 21, and the heat supply exhaust pipe 62 is connected to the other end of the heat exchange tube 21. A fourth flow control element 63 is installed on the heat supply inlet pipe 61, and a fifth flow control element 64 is installed on the heat supply exhaust pipe 62.

[0042] The heat exchanger housing 6 is typically made of metal, such as stainless steel or aluminum alloy, with excellent thermal conductivity. The heat inlet pipe 61 and heat outlet pipe 62 can be rubber or metal tubes. The fourth and fifth flow control elements 63 and 64 are solenoid valves or manual valves. When heating the oil collection tank 3 is required, the fourth and fifth flow control elements 63 and 64 are opened, allowing the hot water in the heat exchange tubes 21 to enter the heat exchanger housing 6 through the heat inlet pipe 61 and then flow out of the heat outlet pipe 62, thereby heating the oil in the oil collection tank 3 and preventing it from solidifying.

[0043] The principle behind this embodiment is that heat exchange tube 21 is routed around the outside of trap 13 and connected to heat source 22. Heat from existing heat source 22 is utilized to heat trap 13, eliminating the need for an external power source and additional circuitry required for electric heating. This reduces installation complexity, maintenance costs, and energy consumption. The presence of oil collection tank 3 and liquid level adjustment assembly 4 allows for the timely discharge of grease from trap 13 and maintains a stable liquid level within the trap, further preventing blockage and odor generation, and enhancing the stability and reliability of the entire drainage system.

[0044] Example 3: This embodiment of the present application provides an application method of a non-blocking and odor-free heated water trap, which uses the non-blocking and odor-free heated water trap in Example 2 for drainage. The method includes the following steps: S1. Install the non-clogging and odor-free heating trap. Connect the water inlet pipe section 11 of the trap body 1 to the drainage equipment and the drain pipe section 12 to the sewer. Route the heat exchange tube 21 around the trap pipe 13 and connect it to the heat source 22. Connect the oil collection pipe 31 to the oil discharge port 133 of the trap pipe 13. The oil discharge pipe 32 is located at the bottom of the oil collection tank 3. Connect the liquid injection pipe 42 to the bent pipe section 131. During installation, ensure that all connections are properly sealed to prevent water leakage.

[0045] When the heat exchange tube 21 is connected to the heat source 22 , the heat exchange tube 21 can be directly connected in series to the shower hot water pipe.

[0046] S2, check the connection status of each component to ensure that the first flow control member 33, the second flow control member 43, the third flow control member 53, the fourth flow control member 63 and the fifth flow control member 64 can all work normally, and the first liquid level detector 41 and the second liquid level detector 54 can accurately detect the liquid level.

[0047] During inspection, the first flow control member 33, the second flow control member 43, the third flow control member 53, the fourth flow control member 63 and the fifth flow control member 64 can be manually operated to observe whether their switch states are normal; the first liquid level detector 41 and the second liquid level detector 54 can be simulated for liquid level detection to see whether they can accurately send signals.

[0048] S3, when the heat source 22 supplies hot water, the hot water flows in the heat exchange tube 21, heats the water trap 13, and softens or melts the grease in the water trap 13.

[0049] At step S4, when the first liquid level detector 41 detects that the liquid level in the trap 13 is too low, the second flow control element 43 opens, adding water to the trap 13 through the liquid boosting pipe 42. When the oil in the trap 13 needs to be drained, the second flow control element 43 also opens, adding a certain amount of water to the trap 13 through the liquid boosting pipe 42 to raise the liquid level and allow the upper layer of oil in the trap 13 to be discharged through the oil drain port 133. During operation, pay attention to the detection results of the first liquid level detector 41 and the operation of the second flow control element 43 to ensure normal liquid level regulation.

[0050] In step S5, the oil-water mixture entering the oil collecting tank 3 is first allowed to stand in the oil-water separation tank 5 to separate the oil and water. When the second liquid level detector 54 detects that the liquid level in the oil-water separation tank 5 is approaching or has reached the tank opening, the third flow control member 53 opens, draining a certain amount of water through the drain pipe 52. The third flow control member 53 is then closed. Only then can the oil-water mixture be discharged into the oil-water separation tank 5 again.

[0051] S6, regularly open the oil drain pipe 32 at the bottom of the oil collecting tank 3 to drain the grease in the oil collecting tank 3.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
