[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0026] This utility model discloses an integrated water purifier and heater, which can be used under the sink as an under-sink water purification device. This integrated water purifier and heater can provide users with purified and pure hot water, which helps to improve the user's cooking experience.

[0027] like Figure 1 As shown, the integrated water purifier and heat pump includes a water filter cartridge 1, a booster pump 2, a heating tank 3, a water outlet mechanism 4, a reversing valve 5, and a hot water pump 6. Specifically, the water filter cartridge 1 includes an RO filter module 102, which is a reverse osmosis filter module used to purify water. The RO filter module 102 has a purified water inlet 105, a pure water outlet 106, and a wastewater outlet 107. The purified water inlet 105 is used to connect to a water source. It should be noted that this connection can be direct, i.e., directly connected to an external water source, or indirect, such as through the pre-filter carbon filter module 101 described below. The water entering the RO filter module 102 through the purified water inlet 105 is purified by the RO filter module 102. The resulting pure water is discharged from the pure water outlet 106, and the concentrated water is discharged from the wastewater outlet 107. Booster pump 2 is connected between the water source and the purified water inlet 105 via the first pipeline 7, providing sufficient power for water to enter the purified water inlet 105. The inlet of the hot water tank 3 is connected to the pure water outlet 106 via the second pipeline 8, and the outlet of the hot water tank 3 is connected to the first valve port of the reversing valve 5 via the third pipeline 9. Hot water pump 6 is mounted on the third pipeline 9. The hot water inlet of the water outlet mechanism 4 is connected to the second valve port of the reversing valve 5 via the fourth pipeline 10, and the third valve port of the reversing valve 5 is connected to the purified water inlet 105 via the fifth pipeline 11. It should be noted that the first valve port is the inlet of the reversing valve 5, and both the second and third valve ports are the outlets of the reversing valve 5. Switching the state of the reversing valve 5 can be done by connecting the first valve port to the second valve port, or by connecting the first valve port to the third valve port.

[0028] This integrated water purifier and heater features a hot tank cleaning mode. When switched to this mode, the first and third ports of the reversing valve 5 connect. Hot water in the hot tank 3 flows sequentially through the hot water pump 6, reversing valve 5, fifth pipeline 11, booster pump 2, and RO filter module 102. After passing through the RO filter module 102, it is split into pure water and concentrated water. The pure water returns to the hot tank 3 through the second pipeline 8, while the concentrated water is discharged through the wastewater outlet 107. This configuration achieves the circulation of hot water in the hot tank 3 within the aforementioned loop. Because the hot water in the hot tank 3 is at a higher temperature, the high-temperature hot water flowing through the aforementioned components and pipelines effectively cleans and sterilizes them, resulting in a more thorough cleaning and better sterilization effect. The hot tank cleaning mode improves the cleanliness of the integrated water purifier and heater, contributing to the health and safety of the user's water supply. It should be noted that by controlling the hot water circulation time to the target duration, multiple circulations of the hot water in the hot tank 3 can be achieved, further enhancing the cleaning and sterilization effects. In one specific embodiment, the target duration is 1.5 minutes, but the time can be adjusted based on the cleaning test results.

[0029] Furthermore, the water purification filter element 1 includes a pre-carbon core module 101, which is used to purify raw water. The pre-carbon core module 101 has a raw water inlet 103 and a purified water outlet 104. The raw water inlet 103 is used to connect to an external water source, such as tap water. The first pipeline 7 connects the purified water outlet 104 and the purified water inlet 105. The third valve port of the reversing valve 5 is connected to the raw water inlet 103 through the fifth pipeline 11. That is, the inlet end of the fifth pipeline 11 is connected to the third valve port of the reversing valve 5, and the outlet end of the fifth pipeline 11 is directly connected to the raw water inlet 103.

[0030] When the integrated water purifier and heat pump is in water purification mode, the raw water entering the pre-filter carbon core module 101 through the raw water inlet 103 is first filtered by the pre-filter carbon core module 101, and the purified water is discharged from the purified water outlet 104. The purified water discharged from the purified water outlet 104 can be passed through the purified water inlet 105 into the RO filter module 102 for purification. The pure water produced is discharged from the pure water outlet 106, and the concentrated water produced can be discharged from the wastewater outlet 107. When the integrated water purifier and heat pump is switched to the hot tank cleaning mode, the hot water in the hot tank 3 flows sequentially through the hot water pump 6, the reversing valve 5, the fifth pipeline 11, the pre-filter carbon core module 101, the booster pump 2, and the RO filter module 102. After passing through the RO filter module 102, it is split into pure water and concentrated water. The pure water flows back to the hot tank 3 through the second pipeline 8, and the concentrated water is discharged through the wastewater outlet 107.

[0031] In some embodiments, the pre-filter carbon core module 101 and the RO filter module 102 are integrated together to form an integrated water purification filter. By integrating the pre-filter carbon core module 101 and the RO filter module 102 together, the integration of the integrated water purification and heating machine is greatly improved, which helps to reduce the space requirements for installing the integrated water purification and heating machine under the sink.

[0032] Optionally, the reversing valve 5 is a three-way solenoid reversing valve. Optionally, the hot water pump 6 is a centrifugal pump. Regarding the structure of the hot water tank 3, it includes a tank body and a heating plate and a liquid level probe located inside the tank body. The heating plate can heat the pure water entering the tank body to a set stable temperature, such as 55°C or 99°C. The liquid level probe can obtain the liquid level of the pure water in the tank body so as to replenish water in a timely manner.

[0033] Optionally, the water outlet mechanism 4 is a display faucet, which can display the water temperature on its screen for greater user convenience. Optionally, the display faucet has multiple water inlets, allowing water of different qualities or temperatures to enter the faucet and be discharged through its drain outlet.

[0034] Continue to refer to Figure 1 As shown, the raw water inlet 103 is connected to an external water source through the water inlet pipe 26. A water inlet valve 27 is installed on the water inlet pipe 26, which can control the opening and closing of the water inlet pipe 26. Optionally, the water inlet valve 27 is a solenoid valve.

[0035] Continue to refer to Figure 1 As shown, the integrated air purifier and heat pump also includes a wastewater discharge pipe 17 and a wastewater valve 18. One end of the wastewater discharge pipe 17 is connected to the wastewater outlet 107, and the other end forms a drain outlet. The wastewater valve 18 is located on the wastewater discharge pipe 17 and is used to control the opening and closing of the wastewater discharge pipe 17. This improves the convenience of wastewater discharge. Optionally, the wastewater valve 18 is a solenoid valve. Optionally, the wastewater discharge pipe 17 and the wastewater outlet 107 are detachably connected. The detachable connection method includes snap-fit, magnetic attraction, etc., which facilitates the replacement and storage of the wastewater discharge pipe 17.

[0036] Continue to refer to Figure 1 As shown, in some embodiments, the integrated water purifier and heater also includes a pure water return pipe 12 and a pure water return valve 13. One end of the pure water return pipe 12 is connected to the pure water outlet 106, and the other end of the pure water return pipe 12 is connected to the first pipe 7, with the connection point located at the front end of the booster pump 2. The pure water return valve 13 is installed on the pure water return pipe 12 and is used to control the on / off state of the pure water return pipe 12. Through the above configuration, the integrated water purifier and heater has a one-button emptying mode for the hot water tank.

[0037] When the water purifier filter 1 of the integrated water purifier and heat pump unit only includes the RO filter module 102, in the one-button emptying mode of the hot water tank 3, the hot water in the hot water tank 3 flows sequentially through the hot water pump 6, the reversing valve 5, the fifth pipeline 11, the booster pump 2, the RO filter module 102, the pure water return pipeline 12, and the pure water return valve 13, and then passes through the booster pump 2 and the RO filter module 102 again before being discharged from the fully open wastewater outlet 107. However, when the water purifier filter 1 of the integrated water purifier and heat pump unit includes both the RO filter module 102 and the pre-filter carbon filter module 101, in the one-button emptying mode of the hot water tank 3, the hot water in the hot water tank 3 flows sequentially through the hot water pump 6, the reversing valve 5, the fifth pipeline 11, the pre-filter carbon filter module 101, the booster pump 2, the RO filter module 102, the pure water return pipeline 12, and the pure water return valve 13, and then passes through the booster pump 2 and the RO filter module 102 again before being discharged from the fully open wastewater outlet 107. This design not only enables the use of hot water in the heating tank 3 to clean, sterilize, and remove stains from the components and pipes it flows through, but also allows for one-button emptying of the hot water in the heating tank 3, preventing pure water from remaining in the tank for extended periods and affecting the user's subsequent experience due to water quality degradation. It should be noted that the hot water in the heating tank 3 can be warm water at 50℃, or water at other temperatures, such as boiling water at 99℃.

[0038] Continue to refer to Figure 1 As shown, a first check valve is also installed on the pure water return pipeline 12. The first check valve ensures that pure water can only flow from the pure water outlet 106 to the first pipeline 7, and cannot flow in the reverse direction.

[0039] Continue to refer to Figure 1 As shown, the integrated water purifier and heater also includes a purified water direct outlet pipe 14 and a purified water control valve 15. The water outlet mechanism 4 has a purified water inlet. One end of the purified water direct outlet pipe 14 is connected to the purified water outlet 104, and the other end of the purified water direct outlet pipe 14 is connected to the purified water inlet. The purified water control valve 15 is installed on the purified water direct outlet pipe 14 and is used to control the on / off state of the purified water direct outlet pipe 14. This configuration allows users to directly select and use the purified water discharged from the purified water outlet 104 according to their needs, without having to purify all the purified water into pure water. This improves the water output rate and reduces the number of times the RO filter module 102 is used, thus extending the service life of the RO filter module 102. Optionally, the purified water control valve 15 is a solenoid valve.

[0040] In some embodiments, the integrated water purifier and heat pump unit further includes a first flow meter 16, which is disposed on the purified water direct outlet pipe 14. The flow rate of the purified water direct outlet pipe 14 can be obtained using the first flow meter 16.

[0041] Furthermore, the purified water direct outlet pipe 14 and the first pipe 7 share a section of pipe to simplify the piping system of the entire integrated water purification and heating unit.

[0042] Continue to refer to Figure 1 As shown, the integrated water purifier and heat pump also includes a wastewater return pipe 19 and a wastewater return valve 20. One end of the wastewater return pipe 19 is connected to the wastewater outlet 107, and the other end is connected to the first pipe 7, with the connection point located at the front end of the booster pump 2. The wastewater return valve 20 is installed on the wastewater return pipe 19 and is used to control the opening and closing of the wastewater return pipe 19. The integrated water purifier and heat pump has a wastewater return mode. In the wastewater return mode, the wastewater discharged from the wastewater outlet 107 flows sequentially through the wastewater return pipe 19, the wastewater return valve 20, the booster pump 2, and the RO filter module 102 to further purify the wastewater, thereby increasing the water output rate. Optionally, the wastewater return valve 20 is a solenoid valve.

[0043] In some embodiments, one end of the wastewater return pipe 19 is connected to the wastewater outlet 107, and the other end of the wastewater return pipe 19 is connected to the purified water direct outlet pipe 14, so that the wastewater flowing out of the wastewater outlet 107 can be discharged through the wastewater return pipe 19, the purified water direct outlet pipe 14, and the water outlet mechanism 4. The wastewater discharged from the water outlet mechanism 4 can be reused, for example, as mopping water or toilet water.

[0044] In some embodiments, a second check valve is also provided on the wastewater return pipeline 19. The second check valve is provided so that wastewater can only flow from the wastewater outlet 107 to the first pipeline 7 and cannot flow in the reverse direction.

[0045] In some embodiments, a first TDS meter is also provided on the first pipeline 7, and the TDS (total dissolved solids) value of the water in the first pipeline 7 can be obtained by using the first TDS meter.

[0046] Continue to refer to Figure 1 As shown, the integrated water purifier and heater also includes a pure water / room temperature pipe 21 and a room temperature water valve 22. One end of the pure water / room temperature pipe 21 is connected to the pure water outlet 106, and the other end is connected to the room temperature water inlet of the water outlet mechanism 4. The room temperature water valve 22 is located on the pure water / room temperature pipe 21 and is used to control the on / off state of the pure water / room temperature pipe 21. This configuration allows users to directly select to use pure water discharged from the pure water outlet 106 according to their needs, without the need to heat the pure water, allowing users to use room temperature pure water. Optionally, the room temperature water valve 22 is a solenoid valve.

[0047] Optionally, one end of the pure water ambient temperature pipeline 21 is connected to the second pipeline 8. This arrangement simplifies the piping system of the entire integrated water purifier and heat pump unit. Further optionally, a second flow meter 23 is installed upstream of the connection point between the second pipeline 8 and the pure water ambient temperature pipeline 21, allowing the flow rate of the pure water outlet 106 to be obtained. Further optionally, a second TDS meter is installed upstream of the connection point between the second pipeline 8 and the pure water ambient temperature pipeline 21, allowing the TDS value (total dissolved solids) of the water in the second pipeline 8 to be obtained.

[0048] Continue to refer to Figure 1 As shown, the integrated water purifier and heat pump also includes a third flow meter 24, which is installed on the fourth pipe 10. The flow rate of the hot water inlet can be obtained by using the third flow meter 24.

[0049] Continue to refer to Figure 1 As shown, the exhaust port of the hot tank 3 is connected to the steam inlet of the water outlet mechanism 4.

[0050] Continue to refer to Figure 1 As shown, the integrated water purifier and heat pump unit also includes a water dispenser interface for connecting the water dispenser 25 to the outside. Optionally, the integrated water purifier and heat pump unit also includes a sixth pipe 26, one end of which is connected to the pure water outlet 106, and the other end forms the water dispenser interface. Optionally, a third check valve is provided on the sixth pipe 26, which ensures that the pure water entering the sixth pipe 26 can only flow towards the water dispenser 25 and cannot flow in the opposite direction.

[0051] In this embodiment, the integrated air purification and heating unit also includes a control mechanism. The control mechanism can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers.
