Description

Technical Field

[0001] This application relates to the field of water purifier technology, specifically to a water circuit structure for an integrated water purifier and heat purifier. Background Technology

[0002] Integrated water purifiers and heaters, providing both room temperature and hot water, are gaining popularity and becoming an indispensable household appliance. Common integrated water purifiers on the market include a filter and a heating tank. Their working principle involves the filter directly outputting purified water from the tap water source, or heating the water in the heating tank before outputting it, thus providing either room temperature or hot water when connected to a tap.

[0003] Integrated water purifiers and heaters typically have a water level detection device inside the heating tank. This device limits the maximum water level in the tank. During water replenishment, when the device detects a high water level, it provides feedback, causing the system to stop replenishing the tank. The detection elements (such as floats or electrodes) of the water level detection device are usually located inside the heating tank. Due to limitations in the installation space of the detection elements and the detection method, the maximum water level is generally lower than the top surface of the heating tank. In other words, when water is replenished to the high water level, the tank is not completely full, and a significant amount of air accumulates in the unfilled space at the top of the tank, increasing the risk of bacterial growth. In addition, most integrated water purifiers and heaters use a pump to draw water from the heating tank to the faucet. This method has some problems. For example, the pump is the largest component in the integrated water purifier and heater, taking up most of the installation space. This limitation hinders the development of integrated water purifiers towards thinner and smaller designs. Moreover, the vibration generated by the pump during operation is not conducive to noise reduction in integrated water purifiers and heaters. Utility Model Content

[0004] This application provides a water circuit structure for an integrated water purifier and heater to improve the technical problems of existing integrated water purifiers, such as the easy growth of bacteria when the heating tank is not full, and the large space occupied and high vibration and noise of the water pump used to draw water from the heating tank.

[0005] The technical solution adopted in this application is as follows:

[0006] A water circuit structure for an integrated water purifier and heater includes a filtration unit, a pure water tank, and a hot water tank. The filtration unit includes a filter element and a booster pump for pressurizing water supply to the filter element. The filter element supplies water to the pure water tank through a water supply pipe. The hot water tank has a water supply inlet and a hot water outlet. The pure water tank can fill the hot water tank to full capacity through the water supply inlet and can continue to supply water to the full hot water tank, thereby pushing the hot water in the hot water tank out through the hot water outlet.

[0007] In this technical solution, the purified water filtered by the filter element can enter the purified water tank for storage through the water replenishment pipeline. The purified water in the purified water tank can then replenish the heating tank, filling it to a full state. After the heating tank heats the water when it is full, it can continue to be replenished through the purified water tank, resulting in a water outlet state where room temperature water enters through the water inlet and hot water is pushed out through the hot water outlet. The pushed-out hot water can be delivered to the faucet of the integrated water purifier and heating machine for users to use, while the room temperature water entering the heating tank fills the gap left by the hot water discharge, keeping the heating tank always full. Therefore, this solution utilizes a method of replenishing the hot water tank from the pure water tank and then pushing the hot water out. Firstly, compared to existing methods that use a pump to draw water from the hot water tank, this method eliminates the need for a dedicated pump, thus saving installation space required for such a pump in the integrated water purifier and heater unit, contributing to its miniaturization and noise reduction. Secondly, as most of the hot water in the tank is gradually discharged through the hot water outlet using the push-out action of room-temperature water, the water temperature gradually decreases, turning from hot to warm water. This ensures a consistent supply of both hot and warm water, improving the user experience. Thirdly, maintaining a full tank effectively prevents external air from entering and accumulating inside, reducing bacterial growth. Furthermore, when the pure water tank is depleted, the filter element can simultaneously replenish the pure water tank while the pure water tank continues to replenish the hot water tank, ensuring a constant flow of warm water from the hot water outlet.

[0008] The pure water tank is connected to the water supply inlet via an outlet pipe, and a water supply pump is installed on the outlet pipe. The pure water tank is connected to the ambient temperature water discharge port of the integrated water purifier and heat pump via an ambient temperature water supply pipe.

[0009] In this technical solution, the pure water tank can not only replenish the hot water tank, but also directly discharge water to the ambient temperature water outlet of the integrated water purifier and heater through the ambient temperature water supply pipeline. Compared with the water supply method of the filter cartridge producing water while simultaneously delivering the produced water to the ambient temperature water outlet, the water pre-stored in the pure water tank can supply a large flow rate to the ambient temperature water outlet, increasing the water output per unit time. In addition, when the pure water tank discharges water to both the hot water tank and the ambient temperature water outlet at the same time, the hot water in the hot water tank is also pushed out at the same time as the ambient temperature water outlet, realizing the simultaneous discharge of ambient temperature water and hot water. It can control the mixing of ambient temperature water and hot water in the faucet of the integrated water purifier and heater, achieving a large flow rate of warm water output.

[0010] The pure water tank is equipped with a heating water supply port and a normal temperature water supply port. The water outlet pipe is connected to the heating water supply port, and the normal temperature water supply pipe is connected to the normal temperature water supply port. The normal temperature water supply pipe is equipped with a water pump. The water replenishment pump and the water outlet pump can be operated selectively or together.

[0011] In this technical solution, when the water replenishment pump is running and the water outlet pump is stopped, the pure water tank replenishes water to the hot water tank, pushing the hot water in the hot water tank out, and the integrated water purifier and heat pump dispenses hot water; when the water replenishment pump is stopped and the water outlet pump is running, the pure water tank dispenses water to the ambient temperature water outlet, and the integrated water purifier and heat pump dispenses ambient temperature water; when the water replenishment pump and the water outlet pump are running together, while water is being dispensed from the ambient temperature water outlet, the hot water in the hot water tank is also being pushed out, achieving simultaneous discharge of ambient temperature water and hot water. When the ambient temperature water and hot water mix in the faucet of the integrated water purifier and heat pump, a large flow of warm water is dispensed. Moreover, by adjusting the duty cycle of the water replenishment pump and the water outlet pump, the flow rate of ambient temperature water and hot water can be adjusted, thereby allowing the two to mix and dispense hot water of different temperatures.

[0012] The water circuit structure of the integrated water purifier and heat pump also includes a one-inlet-two-outlet valve. The outlet pipe is connected to the inlet of the one-inlet-two-outlet valve, the first outlet of the one-inlet-two-outlet valve is connected to the water supply inlet, one end of the ambient temperature water supply pipe is connected to the second outlet of the one-inlet-two-outlet valve, and the other end is connected to the ambient temperature water discharge outlet.

[0013] In this technical solution, the pure water tank and the ambient temperature water outlet are selected for water discharge through the adjustment of the inlet and outlet valve. When the first outlet is opened, the pure water tank replenishes water to the hot water tank, pushing the hot water in the hot water tank out, and the integrated water purifier and heat pump dispenses hot water. When the second outlet is opened, the pure water tank discharges water to the ambient temperature water outlet, and the integrated water purifier and heat pump dispenses ambient temperature water.

[0014] The hot water outlet is connected to the hot water outlet of the integrated water purifier and heat pump via a hot water discharge pipe. A hot water outlet valve is provided on the hot water discharge pipe. The pure water tank is connected to an exhaust pipe. The hot water tank is connected to the exhaust pipe via a pressure relief pipe.

[0015] In this technical solution, the hot tank is connected to the exhaust pipe through the pressure relief pipe. As the hot tank is heated, the hot water rises and generates steam. The steam can flow through the pressure relief pipe toward the exhaust pipe, and is discharged after being cooled by the exhaust pipe, thus avoiding injury from hot steam. In addition, some of the steam will condense in the exhaust pipe, and the condensate formed can be controlled to be discharged from the exhaust pipe or controlled to flow back into the pure water tank.

[0016] The hot water outlet is connected to the inlet of the reversing valve, the first outlet of the reversing valve is connected to the hot water outlet of the integrated water purifier and heat pump through the hot water discharge pipe, and the second outlet of the reversing valve is connected to the wastewater discharge pipe of the filter element through the pressure relief pipe.

[0017] In this technical solution, when the first outlet valve is opened, the pure water tank can replenish water to the hot water tank and push out the hot water. The hot water flows to the hot water discharge port through the reversing valve. When the second outlet valve is opened, the pure water tank cannot replenish water to the hot water tank. The steam generated in the hot water tank due to heating can flow to the wastewater discharge pipeline through the reversing valve and be discharged.

[0018] The water inlet is located at the bottom of the hot water tank, and the hot water outlet is located at the top of the hot water tank.

[0019] In this technical solution, when the pure water tank replenishes water to the hot water tank, room temperature water enters from the water inlet at the bottom of the hot water tank, and hot water is pushed out from the hot water outlet at the top of the hot water tank. Since the density of room temperature water is greater than that of hot water, the hot water mainly concentrates in the upper part of the hot water tank, while the replenished room temperature water mainly concentrates in the lower part of the hot water tank. Therefore, this helps to slow down the mixing of hot water and room temperature water and ensures that during the process of replenishing water from the pure water tank to the hot water tank, the water discharged from the hot water outlet is as much as possible hot water at a high temperature.

[0020] The hot tank is equipped with a water-blocking part. The projection of the water-blocking part on the horizontal plane covers the projection of the water inlet on the horizontal plane, so that the water-blocking part stops the water flow entering from the water inlet and changes the flow direction of the water.

[0021] In this technical solution, the room temperature water added to the hot water tank from the pure water tank is blocked by the water baffle, which changes the flow direction of the room temperature water. The room temperature water turns from its original vertical upward direction to avoid directly rushing towards the hot water at the top, thereby slowing down the mixing of room temperature water and hot water, so as to ensure that as much of the water pushed out from the hot water outlet is at a high temperature.

[0022] Both the water inlet and the hot water outlet are located at the top of the hot water tank. The water inlet is connected to a water guide pipe, which is used to guide the water entering through the water inlet to the bottom of the hot water tank.

[0023] In this technical solution, when the pure water tank replenishes water to the hot water tank, room temperature water enters from the water inlet at the top of the hot water tank and flows to the bottom of the hot water tank under the guidance of the water pipe. The room temperature water pushes the hot water out from the bottom of the hot water tank and the water discharged from the hot water outlet is as hot as possible.

[0024] The hot water tank is equipped with a heating element for heating, which can heat the water as the pure water tank replenishes the hot water tank.

[0025] In this technical solution, during the process of replenishing water from the pure water tank to the hot water tank and pushing out the hot water, the heating element can be controlled to be in a heating state continuously, forming a working mode of heating while water is being dispensed, ensuring that warm water is dispensed throughout the entire water dispensing process.

[0026] The filter element is connected to the ambient temperature water outlet of the integrated air purifier and heat dissipation unit via an ambient temperature water discharge pipe, and an ambient temperature water outlet valve is provided on the ambient temperature water discharge pipe.

[0027] In this technical solution, the filter element can directly discharge water to the ambient temperature water outlet through the ambient temperature water discharge pipe. When this solution is combined with the aforementioned solution where the pure water tank is connected to the ambient temperature water outlet of the integrated water purifier and heater through the ambient temperature water supply pipe, the booster pump can be controlled to run while the water supply pump and the water outlet pump are running together. At this time, while ambient temperature water is discharged from the ambient temperature water outlet and hot water in the hot water tank is pushed out, the filter element also directly discharges ambient temperature water to the ambient temperature water outlet. Water is discharged from all three water lines at the same time. When the water from the three water lines mixes in the faucet of the integrated water purifier and heater, a super-large flow of warm water is achieved, which greatly increases the water flow rate. Moreover, the water discharged from the pure water tank and the water discharged from the hot water tank can dilute the high TDS value water discharged from the filter element, thereby reducing the TDS value of the discharged water.

[0028] Due to the adoption of the above technical solution, the technical effect achieved by this application is as follows: the pure water filtered by the filter element can enter the pure water tank for storage through the water replenishment pipeline. The pure water in the pure water tank can replenish the heating tank, filling it to a full state. After the heating tank heats the water when it is full, it can continue to be replenished through the pure water tank, forming a water outlet state where room temperature water enters through the water replenishment inlet and hot water is pushed out through the hot water outlet. The pushed-out hot water can be delivered to the faucet of the integrated water purifier and heating machine for users to use, while the room temperature water entering the heating tank makes up for the gap left by the hot water discharge, keeping the heating tank always full. Therefore, this solution utilizes a method of replenishing the hot water tank from the pure water tank and then pushing the hot water out. Firstly, compared to existing methods that use a pump to draw water from the hot water tank, this method eliminates the need for a dedicated pump, thus saving installation space required for such a pump in the integrated water purifier and heater unit, contributing to its miniaturization and noise reduction. Secondly, as most of the hot water in the tank is gradually discharged through the hot water outlet using the push-out action of room-temperature water, the water temperature gradually decreases, turning from hot to warm water. This ensures a consistent supply of both hot and warm water, improving the user experience. Thirdly, maintaining a full tank effectively prevents external air from entering and accumulating inside, reducing bacterial growth. Furthermore, when the pure water tank is depleted, the filter element can simultaneously replenish the pure water tank while the pure water tank continues to replenish the hot water tank, ensuring a constant flow of warm water from the hot water outlet.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0038] In the embodiments of this application, a water circuit structure for an integrated water purifier and heat pump is provided, specifically providing... Figure 1 An embodiment of the water circuit structure of the integrated water purifier and heat pump shown is as follows: Figure 2 The illustrated water circuit structure of the integrated water purifier and heat pump is another embodiment. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0039] The water circuit structure of the integrated water purifier and heat pump provided in this application includes a filtration unit, a pure water tank 10, and a hot water tank 11. The filtration unit includes a filter element 12 and a booster pump 13 for pressurizing water into the filter element 12. The filter element 12 replenishes water to the pure water tank 10 through a water supply pipe 14. The hot water tank 11 is provided with a water supply inlet 111 and a hot water outlet 112. The pure water tank 10 can replenish the hot water tank 11 to a full state through the water supply inlet 111, and can continue to replenish water to the full state of the hot water tank 11, thereby pushing the hot water in the hot water tank 11 out from the hot water outlet 112.

[0040] In a preferred embodiment, filter element 12 can be a reverse osmosis filter element or a composite filter element composed of a reverse osmosis membrane and other filter media to improve the filtration effect. The inlet end of booster pump 13 is connected to raw water inlet valve 15. The pure water outlet of filter element 12 can be connected to the inlet end of booster pump 13 through pure water return pipeline 16. The pure water return pipeline 16 is equipped with a first check valve 17. By setting up the pure water return pipeline 16, after the integrated water purifier and heat pump stops discharging water, the reverse osmosis membrane can be flushed with the returned pure water to wash away the inorganic salts, organic pollutants, scale, etc. accumulated on the reverse osmosis membrane, thereby improving the filtration effect of the reverse osmosis membrane and significantly reducing the increase in TDS value of pure water due to the infiltration of inorganic salts into the pure water end of the reverse osmosis membrane when the integrated water purifier and heat pump is stopped. Filter element 12 can also discharge wastewater through wastewater discharge pipeline 18, which is equipped with wastewater valve 19. When the raw water inlet valve 15 is opened, tap water can enter the water circuit structure of the integrated water purifier and heater. Under the pressure of the booster pump 13, it enters the filter element 12 and is filtered into pure water. When the wastewater valve 19 is opened, wastewater can be discharged. The pure water produced by the filter element 12 can enter the pure water tank 10 for storage through the water supply pipe 14. The pure water stored in the pure water tank 10 can be transported to the heating tank 11. In addition, a water tank supply valve 36 can be installed on the water supply pipe 14. When the water tank supply valve 36 is opened, the filter element 12 can replenish water into the pure water tank 10.

[0041] In this technical solution, the pure water filtered by the filter element 12 can enter the pure water tank 10 for storage through the water supply pipe 14. The pure water in the pure water tank 10 can be added to the heating tank 11, filling the heating tank 11 to a full state. After the heating tank 11 heats the water when it is full, it can continue to be replenished through the pure water tank 10, forming a state where room temperature water enters through the water supply inlet 111 and hot water is pushed out from the hot water outlet 112. The pushed-out hot water can be delivered to the faucet of the integrated water purifier and heat pump for users to use, while the room temperature water entering the heating tank 11 makes up for the gap left by the hot water discharge, so that the heating tank 11 is always kept full. Therefore, in this solution, the method of replenishing water to the hot water tank 11 through the pure water tank 10 and pushing out the hot water has several advantages. First, compared to the existing method of drawing water from the hot water tank using a pump, it saves the water pump used to draw water from the hot water tank 11, thus saving the installation space reserved for the water pump in the integrated water purifier and heat pump unit. This contributes to the thinner, smaller size, and vibration and noise reduction of the integrated water purifier and heat pump unit. Second, as most of the hot water in the hot water tank 11 is gradually discharged from the hot water outlet 112 under the action of pushing out the room temperature water, the temperature inside the hot water tank 11 gradually decreases, slowly turning from hot water to warm water. This ensures that the hot water tank 11 outputs hot water at the beginning and warm water at the end, guaranteeing a large supply of hot water and warm water at temperatures higher than room temperature, thus improving the user experience. Third, since the hot water tank 11 is always kept full of water, it effectively prevents external air from entering and accumulating inside the hot water tank 11, thereby reducing bacterial growth. In addition, when the water in the pure water tank 10 is depleted, the filter element 12 can replenish the pure water tank 10 while the pure water tank 10 continues to replenish the water into the hot water tank 11. At the same time, the hot water tank 11 continues to heat the water, so that warm water is always discharged from the hot water outlet 112.

[0042] In a preferred embodiment of this application, the pure water tank 10 is connected to the water supply inlet 111 through the water outlet pipe 20, the water outlet pipe 20 is equipped with a water supply pump 21, and the pure water tank 10 is connected to the ambient temperature water discharge port 23 of the integrated water purifier and heat pump through the ambient temperature water supply pipe 22. In this technical solution, the water replenishment pump 21 on the water outlet pipe 20 is used to draw water from the pure water tank 10 to replenish the hot water tank 11. Moreover, the pure water tank 10 can not only replenish water to the hot water tank 11, but also directly discharge water to the ambient temperature water outlet 23 of the integrated water purifier and heat pump through the ambient temperature water supply pipe 22. Compared with the water supply method of the filter element 12 producing water while delivering the produced water to the ambient temperature water outlet 23, the water pre-stored in the pure water tank 10 can be supplied to the ambient temperature water outlet 23 in a large flow rate, increasing the water output per unit time. In addition, when the pure water tank 10 discharges water to the hot water tank 11 and the ambient temperature water outlet 23 at the same time, the hot water in the hot water tank 11 is also pushed out at the same time as the water is discharged from the ambient temperature water outlet 23, realizing the simultaneous discharge of ambient temperature water and hot water. It can control the mixing of ambient temperature water and hot water in the faucet of the integrated water purifier and heat pump, realizing a large flow of warm water output.

[0043] Regarding the method by which the pure water tank 10 supplies water to the ambient temperature water outlet 23 and the hot water tank 11, the following embodiment 1 or embodiment 2 can be adopted.

[0044] Example 1: As Figure 1 As shown, the pure water tank 10 is provided with a heating water supply port 101 and a normal temperature water supply port 102. The water outlet pipe 20 is connected to the heating water supply port 101, and the normal temperature water supply pipe 22 is connected to the normal temperature water supply port 102. The normal temperature water supply pipe 22 is provided with a water outlet pump 24. The water replenishment pump 21 and the water outlet pump 24 can be operated selectively or together. In this technical solution, when the water supply pump 21 is running and the water outlet pump 24 is stopped, the pure water tank 10 supplies water to the hot water tank 11, pushing out the hot water in the hot water tank 11, and the integrated water purifier and heat pump dispenses hot water; when the water supply pump 21 is stopped and the water outlet pump 24 is running, the pure water tank 10 discharges water to the ambient temperature water outlet 23, and the integrated water purifier and heat pump dispenses ambient temperature water; when the water supply pump 21 and the water outlet pump 24 are running together, while the ambient temperature water outlet 23 is discharging water, the hot water in the hot water tank 11 is also pushed out, realizing the simultaneous discharge of ambient temperature water and hot water. When the ambient temperature water and hot water are mixed in the faucet, a large flow of warm water is dispensed. Moreover, by adjusting the duty cycle of the water supply pump 21 and the water outlet pump 24, the flow rate of ambient temperature water and hot water can be adjusted, thereby mixing the two to produce hot water of different temperatures.

[0045] Example 2: As Figure 2 As shown, the water circuit structure of the integrated water purifier and heat pump also includes a one-in-two-out valve 25. The outlet pipe 20 is connected to the inlet 251 of the one-in-two-out valve 25, the first outlet 252 of the one-in-two-out valve 25 is connected to the water supply inlet 111, one end of the ambient temperature water supply pipe 22 is connected to the second outlet 253 of the one-in-two-out valve 25, and the other end is connected to the ambient temperature water outlet 23. In this technical solution, the one-in-two-out valve 25 adjusts the pure water tank 10, the hot water tank 11, and the ambient temperature water outlet 23 to choose one to discharge water. When the first outlet 252 is open, the pure water tank 10 replenishes water to the hot water tank 11, pushing out the hot water in the hot water tank 11, and the integrated water purifier and heat pump discharges hot water; when the second outlet 253 is open, the pure water tank 10 discharges water to the ambient temperature water outlet 23, and the integrated water purifier and heat pump discharges ambient temperature water.

[0046] When hot water is ejected at hot water outlet 112, regarding the method of achieving hot water discharge, in a preferred embodiment, as follows: Figure 1As shown, the hot water outlet 112 is connected to the hot water outlet 27 of the integrated water purifier and heat pump unit via a hot water discharge pipe 26. A hot water outlet valve 28 is installed on the hot water discharge pipe 26. The pure water tank 10 is connected to an exhaust pipe 29, and the heat tank 11 is connected to the exhaust pipe 29 via a pressure relief pipe 30. In this technical solution, the hot water outlet valve 28 is used to control the opening and closing of the hot water discharge pipe 26. When the hot water outlet valve 28 is open, the hot water pushed out of the hot water outlet 112 can be discharged. The heating tank 11 is connected to the exhaust pipe 29 via the pressure relief pipe 30. As the heating tank 11 heats up, the hot water rises and generates steam. The steam can flow through the pressure relief pipe 30 toward the exhaust pipe 29, where it is cooled and then discharged, preventing hot steam from causing injury. Some of the steam will condense in the exhaust pipe 29, and the resulting condensate can be controlled to either be discharged from the exhaust pipe 29 or flow back into the pure water tank 10. For example, the outlet end of the exhaust pipe 29 can be higher than the inlet end, allowing the condensate to flow back into the pure water tank 10 under gravity. Preferably, a pressure relief valve 31 can be installed on the pressure relief pipe 30. The pressure relief valve 31 has a preset trigger pressure value. When the inlet water pressure from the pure water tank 10 to the heating tank 11 is less than the trigger pressure value, the pressure relief valve 31 closes, preventing hot water from flowing into the exhaust pipe 29 through the pressure relief pipe 30.

[0047] When hot water is ejected at hot water outlet 112, regarding the method of achieving hot water discharge, in another preferred embodiment, such as... Figure 2 As shown, the hot water outlet 112 is connected to the inlet 321 of the reversing valve 32. The first outlet 322 of the reversing valve 32 is connected to the hot water outlet 27 of the integrated water purifier and heat pump unit via the hot water discharge pipe 26. The second outlet 323 of the reversing valve 32 is connected to the wastewater discharge pipe 18 of the filter element 12 via the pressure relief pipe 30. In this technical solution, when the first outlet 322 is open, the pure water tank 10 can replenish water to the heating tank 11, pushing out hot water, which flows through the reversing valve 32 to the hot water outlet 27 for discharge. When the second outlet 323 is open, the pure water tank 10 cannot replenish water to the heating tank 11, and the steam generated in the heating tank 11 due to heating can flow through the reversing valve 32 to the wastewater discharge pipe 18 for discharge. Preferably, the pressure relief pipe 30 can be equipped with a second check valve 35 to prevent wastewater from flowing towards the reversing valve 32 through the pressure relief pipe 30 when the filter element 12 discharges wastewater through the wastewater discharge pipe 18.

[0048] As a preferred embodiment of this application, such as Figure 1As shown, the water inlet 111 is located at the bottom of the heating tank 11, and the hot water outlet 112 is located at the top of the heating tank 11. In this technical solution, when the pure water tank 10 replenishes water to the heating tank 11, room temperature water enters from the water inlet 111 at the bottom of the heating tank 11, and hot water is pushed out from the hot water outlet 112 at the top of the heating tank 11. Since the density of room temperature water is greater than that of hot water, the hot water mainly concentrates in the upper part of the heating tank 11, while the replenished room temperature water mainly concentrates in the lower part of the heating tank 11. Therefore, this helps to slow down the mixing of hot water and room temperature water, ensuring that the water discharged from the hot water outlet 112 during the process of replenishing water from the pure water tank 10 to the heating tank 11 is as much hot water as possible. Furthermore, a water-blocking part can be provided inside the heating tank 11. The projection of the water-blocking part on the horizontal plane covers the projection of the water inlet 111 on the horizontal plane, so that the water-blocking part stops the water flow entering through the water inlet 111 and changes the flow direction of the water. In this technical solution, the room temperature water added to the hot water tank 11 from the pure water tank 10 is blocked by the water baffle, which changes the flow direction of the room temperature water. The room temperature water turns from its original vertical upward direction to avoid directly rushing to the hot water at the top, thereby slowing down the mixing of room temperature water and hot water, so as to ensure that as much of the water pushed out from the hot water outlet 112 is in a high temperature state as possible.

[0049] In another preferred embodiment, such as Figure 2 As shown, the water inlet 111 and the hot water outlet 112 can also be located at the top of the hot water tank 11. The water inlet 111 is connected to a water guide pipe 113, which guides the water entering through the water inlet 111 to the bottom of the hot water tank 11. In this technical solution, when the pure water tank 10 replenishes water to the hot water tank 11, room temperature water enters from the water inlet 111 at the top of the hot water tank 11 and flows to the bottom of the hot water tank 11 under the guidance of the water guide pipe 113. The room temperature water pushes the hot water out from the bottom of the hot water tank 11 and exits through the hot water outlet 112. Since the room temperature water at the bottom is far from the hot water outlet 112, it takes a long time to flow to the top of the hot water tank 11. Therefore, the water discharged from the hot water outlet 112 is as much hot water as possible.

[0050] In a preferred embodiment of this application, the hot water tank 11 is equipped with a heating element 114 for heating. The heating element 114 can perform heating operations during the process of water being replenished from the pure water tank 10 to the hot water tank 11. In this technical solution, during the process of water being replenished from the pure water tank 10 to the hot water tank 11 and hot water being pushed out, the heating element 114 can be controlled to be in a heating state continuously, forming a working mode of heating while water is being dispensed, ensuring that warm water is dispensed throughout the entire water dispensing process.

[0051] As a preferred embodiment of this application, such as Figure 1As shown, the filter element 12 is connected to the ambient temperature water outlet 23 of the integrated air purifier and heat pump through the ambient temperature water outlet pipe 33, and the ambient temperature water outlet pipe 33 is equipped with an ambient temperature water outlet valve 34. In this technical solution, the filter element 12 can directly discharge water to the ambient temperature water outlet 23 through the ambient temperature water discharge pipe 33. When this solution is combined with the aforementioned solution where the pure water tank 10 is connected to the ambient temperature water outlet 23 of the integrated water purifier and heat pump through the ambient temperature water supply pipe 22, the booster pump 13 can also be controlled to run while the water supply pump 21 and the water outlet pump 24 are running together. At this time, while ambient temperature water is discharged from the ambient temperature water outlet 23 and hot water in the hot water tank 11 is pushed out, the filter element 12 also directly discharges ambient temperature water to the ambient temperature water outlet 23. Water is discharged from the three water lines at the same time. When the water from the three water lines mixes in the faucet, a super-large flow of warm water is achieved, which greatly increases the water flow rate. Moreover, the water discharged through the pure water tank 10 and the water discharged through the hot water tank 11 can dilute the high TDS value water discharged by the filter element 12, thereby reducing the TDS value of the discharged water. Furthermore, when filter element 12 discharges room temperature water into room temperature water outlet 23, while water supply pump 21 stops and water supply pump 24 starts, water supply pump 24 draws room temperature water from pure water tank 10. This allows the room temperature water from filter element 12 and pure water tank 10 to be mixed at the faucet before discharge, achieving a large flow rate of room temperature water. Conversely, when filter element 12 discharges room temperature water into room temperature water outlet 23, while water supply pump 24 stops and water supply pump 21 starts, water supply pump 21 draws hot water from hot water tank 11. This allows the room temperature water from filter element 12 to be mixed with the hot water from hot water tank 11 before discharge, achieving a large flow rate of warm water.
