Alternatively, the condenser pipe is fitted over the second end of the first pipe segment, and both the condenser pipe and the first pipe segment extend vertically, with their centerlines collinear.

[0011] In some embodiments, the tank includes a tank body, a top cover, and a bottom cover. The top cover is connected to the tank body, and the bottom cover is connected to the tank body. The bottom cover, the tank body, and the top cover form a heating chamber.

A portion of the exhaust pipe extends into the heating chamber through the through hole.

[0012] In some embodiments, the hot tank assembly further includes a detection component, which includes a water level detection element, a water quality detection element, and a temperature control element.

The temperature control element is connected to the tank body and communicates with the heating chamber, and is used to detect the temperature of the liquid in the heating chamber.

[0013] In some embodiments, the water level detection element includes a high water level probe and a low water level probe, wherein the high water level probe is used to detect the position of the highest water level in the heating chamber and the low water level probe is used to detect the position of the lowest water level in the heating chamber.

[0014] In some embodiments, the temperature control element includes a temperature control fixing plate and a temperature sensor. The temperature control fixing plate is connected to the tank body, and a second through hole communicating with the heating chamber is provided on the temperature control fixing plate. The temperature sensor extends into the heating chamber through the second through hole to detect the temperature of the liquid in the heating chamber.

[0015] In some embodiments, the heating element is disposed within the heating chamber.

[0016] The second aspect of this application provides an integrated air purifier and heat pump, which includes a housing assembly, a heating tank assembly as described above, and a filtration system. The housing assembly has an inner cavity; the tank, heating element, exhaust pipe, and condenser pipe are all installed in the inner cavity; the filtration system is installed in the inner cavity and is used to provide filtered liquid to the heating chamber of the heating tank assembly.

Furthermore, the inner diameter of the condenser pipe is larger than that of the exhaust pipe, facilitating the formation of condensate. Under gravity, the condensate flows back from the exhaust pipe into the heating chamber, reducing the possibility of dripping water from the faucet and thus minimizing water waste.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] Please see Figures 1-2This application provides an integrated water purifier and heater 1, which is a device that integrates water purification and heating functions. The integrated water purifier and heater 1 includes a housing assembly 10, a heating tank assembly 20, and a filtration system 50.

[0035] The housing assembly 10 has an inner cavity 101, in which the heating tank assembly 20 and the filtration system 50 are both installed. That is, the inner cavity 101 can be divided into a heating tank cavity 102 and a filtration cavity 103, which are spaced apart. The heating tank assembly 20 is installed in the heating tank cavity 102, and the filtration system 50 is installed in the filtration cavity 103. The housing assembly 10 protects the heating tank assembly 20 and the filtration system 50, reducing the probability of damage to them. It is understood that the housing assembly 10 can be made of at least one of metal and plastic. For example, the housing assembly 10 can be made of metal to give it high structural strength, reducing the probability of damage and consequently reducing the probability of damage to the heating tank assembly 20 and the filtration system 50, thus extending the service life of the integrated heat purifier 1. Alternatively, the housing assembly 10 can be made of plastic, which offers advantages such as high structural strength, light weight, and low cost.

[0036] Please see Figures 2-3 Furthermore, the integrated water purifier and heating unit 1 also includes a faucet 2, which can be connected to the housing assembly 10 via a pipe. That is, the water outlet of the heating tank assembly 20 and the water outlet of the filtration system 50 can be located on the housing assembly 10. The faucet 2 is connected to the water outlets of the heating tank assembly 20 and the filtration system 50 on the housing assembly 10 via a pipe, so that the faucet 2 is connected to the heating tank assembly 20 and the filtration system 50. When the faucet 2 is turned on, hot water from the heating tank assembly 20 or room temperature water from the filtration system 50 can flow out through the faucet 2 to provide hot or room temperature water to the user. It is understood that the integrated water purifier and heating unit 1 can have two faucets 2, one connected to the heating tank assembly 20 and the other connected to the filtration system 50, thus providing hot and room temperature water to the user independently. In other embodiments, the faucet 2 can also be connected to both the heating tank assembly 20 and the filtration system 50, and the flow of hot or room temperature water can be controlled by a switch.

[0037] It is understandable that the faucet 2 can also be a smart faucet 2. When the controller 80 detects a signal for taking room temperature water or a water replenishment signal for the hot water tank component 20 at the smart faucet 2, the controller 80 can control the filtration system 50 to start water production, so as to ensure that users can take room temperature water and hot water from the smart faucet 2 in a timely manner, reduce the user's waiting time, and improve the user experience.

[0038] The heating tank assembly 20 is connected to the faucet 2 and the filtration system 50. The heating tank assembly 20 can heat the liquid filtered by the filtration system 50 and provide hot water to the user after the faucet 2 is turned on.

[0039] Please see Figure 3 The filtration system 50 can be connected to a tap water pipe. The filtration system 50 includes a filter element, a booster pump 54, and an inlet valve 51. Both the booster pump 54 and the inlet valve 51 are electrically connected to the controller 80. When the controller 80 detects a signal for room temperature water intake from the faucet 2 or a water replenishment signal from the heating tank assembly 20, it controls the filtration system 50 to start water production. When these two signals disappear, the controller 80 controls the filtration system 50 to stop water production and enter standby mode. The purified water from the outlet of the filtration system 50 can enter the heating tank assembly 20 or flow directly out through the faucet 2.

[0040] For example, the filtration system 50 may include multiple filter elements, which may be set up independently or integrated into a composite filter element.

[0041] Please continue reading. Figure 3 Specifically, the filtration system 50 may include an inlet valve 51, a first filter element 52, a second filter element 53, a booster pump 54, and a one-way valve 55. The inlet end of the inlet valve 51 is connected to the raw water inlet, the outlet end of the inlet valve 51 is connected to the inlet end of the first filter element 52, the outlet end of the first filter element 52 is connected to the inlet end of the booster pump 54, the outlet end of the booster pump 54 is connected to the inlet end of the second filter element 53, the outlet end of the second filter element 53 is connected to the inlet end of the one-way valve 55, and the outlet end of the one-way valve 55 is connected to the outlet end of the filtration system 50.

[0042] The first filter element 52 is used for preliminary filtration of raw water. It can filter out large particles such as mud, rust, insect eggs, and red worms from the raw water. The raw water can be tap water, well water, etc. The first filter element 52 can be a PP cotton filter element (polypropylene melt-blown filter element), carbon rod filter element, composite filter element, etc.

[0043] The second filter element 53 contains a reverse osmosis membrane, which can be an artificial semi-permeable membrane. The membrane pore size is extremely small, effectively removing dissolved salts, colloids, microorganisms, organic matter, and other impurities from the water. The water filtered by the second filter element 53 obtained by the user through the faucet 2 is pure water; that is, a pure water outlet pipe is connected between the second filter element 53 and the faucet 1. A wastewater pipe 531 is also connected to the second filter element 53, and a wastewater solenoid valve 532 can be installed on the wastewater pipe 531 to control wastewater discharge.

[0044] In other embodiments, the filtration system 50 may further include a third filter element, the inlet of which is connected to the outlet of the second filter element 53, and the outlet of the third filter element is connected to the outlet of the filtration system 50.

[0045] The third filter element is used to adsorb odors and residual chlorine, and can be used to improve the taste of room temperature water. The third filter element can be an activated carbon filter element.

[0046] Understandably, to facilitate the replenishment of water to the heating tank assembly 20 from the outlet of the filtration system 50, and to directly supply room temperature water to the faucet 2, the heating tank assembly 20 may include an inlet pipe 25 and a water replenishment valve 251 installed on the inlet pipe 25. When the heating tank assembly 20 needs replenishment, the water replenishment valve 251 opens, allowing room temperature water from the outlet of the filtration system 50 to enter the heating tank assembly 20. When the user needs to use room temperature water, the water replenishment valve 251 can be closed, or it can be opened, allowing room temperature water from the outlet of the filtration system 50 to flow out through the faucet 2.

[0047] Please continue reading. Figure 3 Of course. In other embodiments, the filtration system 50 can also be connected to the water dispenser 3 via a pipeline; that is, the water outlet of the filtration system 50 and the water dispenser 3 are connected via a pipeline to provide room temperature water to the water dispenser 3.

[0048] The hot tank assembly 20 will be described in detail below.

[0049] Please see Figures 4-5 The heated tank assembly 20 includes a tank body 21 and a heating element 22. The tank body 21 has a heating chamber 21a, which can be used to hold liquid. The heating element 22 is connected to the tank body 21 to heat the liquid in the heating chamber 21a. It is understood that the heating element 22 can be installed on or near the outer wall of the tank body 21 to transfer heat to the liquid in the heating chamber 21a through thermal conduction, thereby heating the liquid in the heating chamber 21a; or, the heating element 22 can be installed inside the heating chamber 21a and connected to the tank body 21, so that the heating element 22 can directly heat the liquid in the heating chamber 21a. It should be noted that this embodiment of the application uses the heating element 22 being disposed inside the heating chamber 21a as an example.

[0050] Please see Figure 2 as well as Figure 4 Furthermore, the integrated heat and water purifier 1 may also include a controller 80, wherein when the heating element 22 is located in the heating chamber 21a, the terminal 221 of the heating element 22 can penetrate the tank 21 so that the terminal 221 extends out of the outer wall of the tank 21, so that the controller 80 can be electrically connected to the terminal 221, thereby facilitating the controller 80 to control the heating element 22 to work according to the set program, thereby realizing the heating of the liquid in the heating chamber 21a.

[0051] Please see Figures 4-5 The heating tank assembly 20 also includes an exhaust pipe 24, which is connected to the tank body 21 and communicates with the heating chamber 21a. It is understood that when the heating element 22 is working, it heats the liquid in the heating chamber 21a, causing the liquid temperature to gradually rise. This intensifies the activity of water molecules, and some water molecules gain enough energy to break free from the liquid state and transform into a gaseous state. In other words, some water in the heating chamber 21a is converted into water vapor, resulting in an increase in internal pressure. If the water vapor in the heating chamber 21a cannot be discharged in time, it may lead to excessive internal pressure in the heating tank assembly 20, causing safety hazards such as rupture or leakage. Therefore, this embodiment provides an exhaust pipe 24 communicating with the heating chamber 21a. The exhaust pipe 24 can be used to discharge the water vapor generated during the heating process in the heating chamber 21a, ensuring the safety of the tank body 21 during use. In addition, after the water vapor in the heating chamber 21a is discharged from the exhaust pipe 24, the air content in the heating chamber 21a can be reduced, so that the heat can be more concentrated on the water molecules, thereby improving the heating efficiency of the tank 21.

[0052] The exhaust pipe 24 can be made of silicone; that is, silicone, due to its excellent high-temperature resistance, corrosion resistance, and flexibility, is widely used in the exhaust pipe 24 of the integrated water purifier and heat pump 1. It can not only withstand the impact of high-temperature steam inside the tank 21 without easily deforming or being damaged, but also adapt to the complex internal structure of the integrated water purifier and heat pump 1, ensuring a tight connection and preventing air leakage. Furthermore, silicone is non-toxic and odorless, meeting food safety standards. Of course, the exhaust pipe 24 can also be made of other suitable materials.

[0053] In related technologies, the integrated heat and water purifier 1 has a condensation box inside, which is mainly formed by injection molding and welding. This results in a higher manufacturing cost for the integrated heat and water purifier 1 and a larger space occupied by the condensation box, leading to a larger overall size of the integrated heat and water purifier 1.

[0054] Please continue reading. Figures 4-5 To address the aforementioned issues, the heating tank assembly 20 further includes a condenser pipe 28, which is connected to and communicates with the exhaust pipe 24. The inner diameter of the condenser pipe 28 is larger than that of the exhaust pipe 24. Understandably, when water vapor is generated in the heating chamber 21a during heating and is discharged from the exhaust pipe 24, the condenser pipe 28, being connected to the exhaust pipe 24, can condense most of the water vapor discharged from the exhaust pipe 24 into condensate, forming water droplets. Under the influence of gravity, the condensate can flow back into the heating chamber 21a through the exhaust pipe 24, significantly reducing the overflow of water vapor from the water outlet (faucet 2 or water dispenser 3, etc.) and preventing scalding of users by high-temperature steam.

[0055] Furthermore, by setting the inner diameter of the condenser tube 28 to be larger than that of the exhaust pipe 24, water vapor is more easily condensed into condensate and forms water droplets, which facilitates the return of the condensate to the heating chamber 21a. This reduces the possibility of water dripping from the tap, thus minimizing water waste. The material of the condenser tube 28 can include stainless steel, copper, and aluminum, etc., and this embodiment does not specifically limit the material of the condenser tube 28. However, it should be noted that the material of the condenser tube 28 is different from that of the exhaust pipe 24 to ensure that the condenser tube 28 achieves the desired condensation effect on water vapor.

[0056] This embodiment connects and communicates a condenser pipe 28 with an exhaust pipe 24, allowing the condenser pipe 28 to condense most of the water vapor discharged from the exhaust pipe 24 into condensate, significantly reducing the amount of water vapor ejected. This is particularly effective when the integrated water purifier and heater 1 is connected to a faucet 2; because the water vapor is condensed by the condenser pipe 28, the amount of water vapor ejected from the faucet 2 is greatly reduced, thus preventing scalding of the user by high-temperature steam. Furthermore, the inner diameter of the condenser pipe 28 is larger than that of the exhaust pipe 24, facilitating the formation of condensate. Under gravity, the condensate flows back from the exhaust pipe 24 into the heating chamber 21a, reducing the possibility of dripping from the faucet 2 and thus miniaturizing water. Compared to related technologies, this embodiment uses a condenser pipe 28 to condense the water vapor, reducing manufacturing costs and facilitating the miniaturization of the integrated water purifier and heater 1. In summary, the use of the integrated water purifier and heater 1 is improved by incorporating the condenser pipe 28.

[0057] It should be noted that the type of heating element 22 is not specifically limited in this application embodiment. For example, the heating element 22 can be an electric heating wire heating element 22, a Positive Temperature Coefficient (PTC) ceramic plate heating element 22, etc. The electric heating wire heating element 22 uses the thermal effect of electric current to convert electrical energy into heat energy to heat the liquid in the heating chamber 21a; the PTC ceramic plate heating element 22 uses the constant-temperature heating characteristics of a PTC thermistor to achieve constant-temperature heating of the liquid in the heating chamber 21a.

[0058] In some embodiments, the inner diameter of the condenser tube 28 is greater than or equal to 8 mm; that is, the inner diameter of the condenser tube 28 can be 8 mm, 10 mm, 12 mm, etc. In this case, the inner diameter of the condenser tube 28 is relatively large, which allows the water vapor discharged from the exhaust pipe 24 to condense into condensate. Since the condensate is in the form of droplets and is subject to gravity, it is easy for the condensate to flow back into the heating chamber 21a. If the inner diameter of the condenser tube 28 is less than 8 mm, the inner diameter of the condenser tube 28 is relatively small. When the exhaust pipe 24 discharges water vapor, the condensate will easily condense into a water column inside the condenser tube 28 due to the smaller inner diameter. This water column will then be pushed out to the faucet 2 by the water vapor continuously generated in the heating chamber 21a, resulting in a reduction in the exhaust effect of the exhaust pipe 24.

[0059] Please see Figure 6 In some embodiments, the tank body 21 includes a tank body 211, a top cover 212, and a bottom cover 213.

[0060] Specifically, the tank body 21 is typically made of food-grade stainless steel to ensure the safety and hygiene of the liquid. These materials are structurally stable, heat-resistant, and rust-resistant, meeting the usage requirements of the tank body 21. The top cover 212 is connected to the top of the tank body 211, and the bottom cover 213 is connected to the bottom of the tank body 211; that is, the top cover 212, tank body 211, and bottom cover 213 can be connected by welding, screwing, or other methods to achieve a sealed connection. The bottom cover 213, tank body 211, and top cover 212 together form a heating chamber 21a to ensure the sealing of the heating chamber 21a.

[0061] Furthermore, due to the effect of thermal convection, the water vapor generated in the heating chamber 21a during the heating process will naturally rise. In this embodiment, the exhaust pipe 24 is provided on the tank top cover 212; that is, the tank top cover 212 is provided with a first through hole 2121, the exhaust pipe 24 is connected to the tank top cover 212, and another part of the exhaust pipe 24 extends into the heating chamber 21a through the first through hole 2121, so that the exhaust pipe 24 communicates with the heating chamber 21a, so that the water vapor generated in the heating chamber 21a during the heating process can be discharged from the exhaust pipe 24. Moreover, the condenser pipe 28 is located above the exhaust pipe 24; that is, in the height direction of the tank body 21, the height of the condenser pipe 28 is higher than the height of the exhaust pipe 24, so that the condenser pipe 28 can be connected to the exhaust pipe 24 at the end away from the tank body 21, and so that the condensate in the condenser pipe 28 can flow back into the heating chamber 21a through the exhaust pipe 24.

[0062] Please see Figure 4The hot tank assembly 20 also includes a drain pipe 27, which can be installed on the top cover 212 of the tank and is connected to the heating chamber 21a so as to discharge the liquid in the heating chamber 21a out of the heating chamber 21a.

[0063] Please see Figures 6-7 In some embodiments, the exhaust pipe 24 includes a first pipe section 241 and a second pipe section 242.

[0064] Specifically, the first end of the first pipe segment 241 extends into the heating chamber 21a through the first through hole 2121, so that the first pipe segment 241 communicates with the heating chamber 21a; the first end of the second pipe segment 242 is connected to the second end of the first pipe segment 241; that is, the first end of the second pipe segment 242 can be connected to the second end of the first pipe segment 241 by welding, sleeve, or forming into one piece. When the first end of the second pipe segment 242 is sleeved with the first end of the first pipe segment 241, the inner diameter of the second pipe segment 242 is larger than the inner diameter of the first pipe segment 241. The second end of the second pipe section 242 is connected to the condenser pipe 28, and the inner diameter of the condenser pipe 28 is larger than the inner diameter of the second pipe section 242. That is, the water vapor generated in the heating chamber 21a during the heating process flows through the first pipe section 241 and the pipe section to the condenser pipe 28. Since the inner diameter of the condenser pipe 28 is larger than the inner diameter of the second pipe section 242, the condensate formed by the water vapor in the condenser pipe 28 flows back to the heating chamber 21a along the second pipe section 242 and the first pipe section 241.

[0065] Furthermore, the first pipe section 241 extends vertically, and at least part of the second pipe section 242 extends laterally; thus, it is convenient for the condensate in the condenser tube 28 to flow back into the heating chamber 21a along the second pipe section 242 and the first pipe section 241.

[0066] It should be noted that the above-mentioned vertical extension can be understood as extending along the height direction of the tank 21; the above-mentioned lateral extension can be understood as extending along the horizontal direction of the tank 21, or extending in a direction that forms an angle with the horizontal direction of the tank 21.

[0067] Please continue reading. Figures 6-7 In some embodiments, the condenser tube 28 extends vertically; that is, the direction in which the condenser tube 28 extends vertically can be consistent with the height direction of the tank 21, or it can be set at an angle to the height direction of the tank 21, and the condenser tube 28 is located above the exhaust pipe 24. In this way, the condensate formed in the condenser tube 28 can flow back to the exhaust pipe 24, and then flow back to the heating chamber 21a from the exhaust pipe 24.

[0068] Please see Figures 8-9In some embodiments, the projection of the condenser pipe 28 is taken along the height direction of the tank body 21, and the projection of the condenser pipe 28 is located outside the projection of the tank top cover 212. In this way, the connection between the condenser pipe 28 and the exhaust pipe 24 is located outside the tank top cover 212, so as to avoid the arrangement of other components connected to the tank top cover 212 being affected due to the connection between the condenser pipe 28 and the exhaust pipe 24. Thus, the space utilization of the hot tank assembly 20 is improved.

[0069] In other embodiments, the exhaust pipe 24 includes a first pipe section 241, the first end of which extends into the heating chamber 21a via a first through hole 2121, thereby communicating with the heating chamber 21a. The second end of the first pipe section 241 is connected to the condenser pipe 28. This application does not specifically limit the arrangement of the first pipe section 241 and the condenser pipe 28.

[0070] For example, the first pipe section 241 extends vertically, and the center line of the condenser pipe 28 is set at an angle to the center line of the first pipe section 241. The condenser pipe 28 extends upward and away from the center of the tank top cover 212. At this time, the first pipe section 241 is set vertically, and the condenser pipe 28 extends away from the tank top cover 212. The center line of the first pipe section 241 and the center line of the condenser pipe 28 form an angle to accelerate the speed at which condensate flows back into the first pipe section 241.

[0071] For example, the condenser tube 28 is sleeved on the second end of the first pipe section 241, and both the condenser tube 28 and the first pipe section 241 extend vertically and their center lines are collinear; in this way, both the condenser tube 28 and the first pipe section 241 are in the vertical direction, so as to accelerate the speed at which condensate flows back into the first pipe section 241.

[0072] The above explains the arrangement of the exhaust pipe 24 on the tank top cover 212. In some other embodiments, the exhaust pipe 24 may also be arranged on the tank body 211. It is understood that the tank body 211 has a through hole, the exhaust pipe 24 is connected to the tank body 211 and located near the tank top cover 212, and a portion of the exhaust pipe 24 extends into the heating chamber 21a through the through hole; that is, a through hole is provided at the top of the tank body 211, and a portion of the exhaust pipe 24 extends into the heating chamber 21a through the through hole, so that the exhaust pipe 24 communicates with the heating chamber 21a. Furthermore, the end of the exhaust pipe 24 away from the tank body 211 is connected to the condenser pipe 28. In this case, the condenser pipe 28 can extend vertically, or the centerline of the condenser pipe 28 can be angled with the centerline of the exhaust pipe 24; this facilitates the return of condensate formed by water vapor in the condenser pipe 28 to the heating chamber 21a.

[0073] Please see Figure 6In some embodiments, in order to ensure the normal operation of the hot tank assembly 20 and the safe heating of the liquid in the heating chamber 21a, the hot tank assembly 20 also includes a detection assembly 23, which includes a water level detection element 232, a water quality detection element, and a temperature control element 237.

[0074] Specifically, the water level detection element 232 is connected to the tank 21 and communicates with the heating chamber 21a, so that the water level detection element 232 can detect the water level in the heating chamber 21a. This embodiment does not specifically limit the type of water level detection element 232. For example, the water level detection element 232 can be one of a float-type water level sensor, an electrode-type water level sensor, or a capacitive water level sensor. The float-type water level sensor detects changes in water level by the up-and-down movement of a float. When the water level rises, the float rises; when the water level falls, the float falls. The movement of the float triggers a switch inside the float-type water level sensor, thereby outputting a corresponding electrical signal to the controller 80 to detect the water level in the heating chamber 21a. The electrode-type water level sensor detects the water level by placing electrodes in the heating chamber 21a and utilizing the conductivity of water. When the water level rises and contacts the electrode, the circuit is activated, outputting an electrical signal to the controller 80 to detect the water level within the heating chamber 21a. The capacitive water level sensor detects the water level by measuring the capacitance between the sensor and the water level. As the water level rises, the capacitance changes, resulting in a corresponding electrical signal being output to the controller 80 for further detection of the water level within the heating chamber 21a.

[0075] Please continue reading. Figure 6 Furthermore, in some embodiments, the water level detection element 232 includes a high water level probe 233 and a low water level probe 234. It is understood that the high water level probe 233 is used to detect the position of the highest water level in the heating chamber 21a, and the low water level probe 234 is used to detect the position of the lowest water level in the heating chamber 21a; that is, when the liquid in the heating chamber 21a rises to the highest water level, the water inlet pipe 25 stops supplying water to the heating chamber 21a to prevent the liquid in the heating chamber 21a from overflowing; when the liquid in the heating chamber 21a drops to the lowest water level, the water inlet pipe 25 supplies water to the heating chamber 21a to prevent the heating chamber 21a from drying out.

[0076] It should be noted that the embodiments of this application do not specifically limit the positions of the high water level probe 233 and the low water level probe 234 on the tank body 21.

[0077] Please continue reading. Figure 6In another embodiment, the water level detection element 232 may include two high water level probes 233 and one low water level probe 234. The two high water level probes 233 may be disposed on the tank top cover 212, and the high water level positions detected by the two high water level probes 233 are not identical; that is, there are first and second high water level positions within the heating chamber 21a, and the first high water level position is higher than the second high water level position in the height direction of the tank body 21. In this case, one high water level probe 233 is used to detect the first high water level position, and the other high water level probe 233 is used to detect the second high water level position. Even if the other high water level probe 233 malfunctions, detection can still be performed using the first high water level probe 233, thereby improving the accuracy of the high water level detection. Furthermore, the low water level probe 234 may be disposed on the tank top cover 212 or the tank bottom cover 213 to detect the lowest water level position within the heating chamber 21a.

[0078] The water quality detection element is connected to the tank 21 and communicates with the heating chamber 21a; that is, the water quality detection element is used to detect the quality of the liquid in the heating chamber 21a to ensure that the user is provided with safe and hygienic liquid. This application embodiment does not specifically limit the type of water quality detection element; for example, the water quality detection element can be an electrochemical sensor, a biosensor, etc.

[0079] The temperature control element 237 is connected to the tank body 21 and communicates with the heating chamber 21a; that is, a portion of the temperature control element 237 extends into the heating chamber 21a so that the temperature control element 237 can detect the temperature of the liquid in the heating chamber 21a. The temperature control element 237 may be disposed on the top cover 212 of the tank or on the body 211 of the tank, and this embodiment does not specifically limit the placement of the temperature control element 237.

[0080] Furthermore, in some embodiments, the temperature control element 237 includes a temperature control fixing plate 2371 and a temperature sensor 2372. Specifically, the temperature control fixing plate 2371 is connected to the tank body 21; that is, when the temperature control element 237 is installed on the tank body 211, the temperature control fixing plate 2371 can be fixed to the tank body 211, the tank top cover 212, or the tank bottom cover 213 by welding, screwing, snapping, or bonding. The temperature control fixing plate 2371 is provided with a second through hole 2373 communicating with the heating chamber 21a. This allows the temperature sensor 2372 to extend into the heating chamber 21a through the second through hole 2373, so that the temperature sensor 2372 can detect the temperature of the liquid in the heating chamber 21a. When the temperature of the liquid is too high, the controller 80 can control the heating element 22 to stop heating, thereby protecting the tank body 21.

[0081] In some embodiments, the integrated air purifier and heating unit 1 also includes a silicon controlled rectifier (SCR), which is a high-power semiconductor device with a four-layer structure having three PN junctions. The SCR operates based on a composite structure formed by the mutual coupling of its PNP and NPN transistors. When a forward voltage is applied to the anode and a forward trigger voltage is applied to the gate electrode, the NPN transistor inside the SCR first conducts, subsequently causing the PNP transistor to conduct as well. Because these two transistors are mutually coupled, the positive feedback after conduction causes a rapid increase in current, ultimately bringing the entire SCR to a low-resistance state, thus achieving conduction. Once triggered, the SCR remains in the conducting state even if the trigger voltage at the gate electrode disappears, until the anode current drops below a specific sustaining current, at which point it returns to the off state.

[0082] Furthermore, a thyristor is mounted on the controller 80, wherein the thyristor is electrically connected to the heating element 22 to control the heating power of the heating element 22. It can be understood that the output terminal of the thyristor is electrically connected to the terminal 221 of the heating element 22, so that the thyristor controls the heating power of the heating element 22; that is, when the heating element 22 needs to heat the liquid in the heating chamber 21a, the thyristor controls the heating power of the heating element 22 to be greater than or equal to 150W, so as to accelerate the heating speed of the liquid in the heating chamber 21a; when the heating element 22 heats the liquid in the heating chamber 21a to above 95 degrees Celsius, the thyristor can control the heating power of the heating element 22 to be less than 150W, thus reducing the heat transferred to the liquid in the heating chamber 21a in the same time, thereby reducing the water vapor content in the heating chamber 21a.

[0083] Please refer to 6- Figure 7 In some embodiments, the integrated water purifier and heat pump 1 also includes a water outlet assembly 90 and a water pump 30.

[0084] Specifically, the water outlet assembly 90 and the water pump 30 are both installed inside the housing assembly 10, and the housing assembly 10 serves to protect the water outlet assembly 90 and the water pump 30. The water pump 30 is installed in the inner cavity 101 and is connected to the heating cavity 21a to pump water from the heating cavity 21a to the water outlet assembly 90. It is understood that the water pump 30 is installed inside the heating tank chamber 102 and is connected to the heating chamber 21a. The working principle of the water pump 30 is based on the conversion of negative pressure and pressure, and the drive of the electric motor. That is, when the user needs hot water, the controller 80 controls the electric motor of the water pump 30 to work. The electric motor drives the piston or impeller inside the water pump 30 to rotate, so as to form a negative pressure in the pump chamber. This negative pressure causes the liquid in the heating chamber 21a to be drawn into the pump chamber. As the piston or impeller continues to rotate, the liquid in the pump chamber is compressed and pressure is generated. This pressure pushes the water flow to the water outlet assembly 90. The water outlet assembly 90 is connected to the faucet 2, so the liquid pumped by the pressure pump is delivered to the faucet 2 through the water outlet assembly 90 for the user to use hot water.

[0085] Furthermore, in some embodiments, the integrated water purifier and heat pump 1 further includes an exhaust connection pipe, which connects to the condenser pipe 28 and the water outlet assembly 90; that is, the end of the condenser pipe 28 away from the exhaust pipe 24 is connected to the exhaust connection pipe, which is also connected to the water outlet assembly 90, and the water outlet assembly 90 is connected to the faucet 2, so that both water vapor and hot water flow out from the faucet 2. Of course, in another embodiment, the housing assembly 10 has an air outlet 104 and a hot water outlet 105, and the integrated water purifier and heat pump 1 further includes an exhaust connection pipe, one end of which is connected to the condenser pipe 28, and the other end of which is connected to the air outlet 104; while the water outlet assembly 90 is connected to the hot water outlet 105. In this way, the faucet 2 can be connected to the air outlet 104 and the hot water outlet 105 through the pipe, thereby realizing the connection between the faucet 2 and the exhaust connection pipe and the water outlet assembly 90, so that both water vapor and hot water can flow out from the faucet 2.

[0086] In addition, the water purifier and heater 1 of this application can also enable users to obtain the set water temperature; that is, users can also obtain warm water with a temperature between room temperature water and hot water discharged from the heating tank component 20 from the faucet 2.

[0087] Specifically, the integrated water purifier and heater 1 in this embodiment also includes a first temperature sensor and a second temperature sensor; the filter assembly 50 also includes a pure water outlet pipe, one end of which is connected to the second filter element 53, and the other end has two branches, one branch which delivers pure water to the heating chamber 21a, and the other branch which delivers pure water directly to the faucet 2, and intersects with the water outlet assembly 90 at the faucet 2.

[0088] The booster pump 54 is connected to the pure water outlet pipe. By adjusting its own duty cycle, it controls the operating power and outputs different pure water flow rates. The duty cycle can be determined by the temperature setting selected by the user.

[0089] The faucet 2 serves as a water-using terminal, used to receive pure water from the pure water outlet pipe and hot water from the water outlet component 90, and to mix the two to form warm water at the set temperature.

[0090] The first temperature sensor can be installed in the tank 21 or the water outlet assembly 90 to monitor the temperature of the hot water in the heating chamber 20a and feed the data back to the controller 80.

[0091] The second temperature sensor is installed in the pure water outlet pipe to detect the temperature of the pure water in the outlet pipe and feed the data back to the controller 80.

[0092] The controller 80 receives data from the first and second temperature sensors and, based on this temperature data, controls the operating power of the water pump 30 and the booster pump 54 to regulate the flow of hot and pure water, ultimately producing water at the user-set temperature at the faucet 2. In this embodiment, the controller 80 controls the operating power of the water pump 30 and the booster pump 54 by controlling their duty cycles.

[0093] For example, users can select a specific temperature setting on the operation interface of the water purifier and heater 1 according to their water temperature requirements, such as the common 45℃ or 55℃.

[0094] When the user selects a temperature setting, the controller 80 adjusts the duty cycle of the booster pump 54 according to a preset correspondence. For example, when the user selects a 45℃ temperature setting, the duty cycle of the booster pump 54 is set to 85%; if the user selects a 55℃ temperature setting, the duty cycle is set to 75%. Through this duty cycle adjustment, the booster pump 54 can deliver pure water to the faucet 2 at a corresponding flow rate. Adjusting the duty cycle essentially controls the operating time of the booster pump 54, thereby controlling the flow rate of pure water and ensuring that an appropriate amount of low-temperature pure water is involved in the mixing process.

[0095] While the booster pump 54 begins supplying pure water, the first temperature sensor continuously monitors the temperature of the hot water in the heating chamber 20a, and the second temperature sensor simultaneously detects the temperature of the pure water in the pure water outlet pipe. These two temperature sensors acquire temperature data in real time and transmit it to the controller 80, providing temperature data for the calculation and control of the duty cycle of the subsequent water pump 30.

[0096] After receiving the detected values ​​of the pure water temperature and the hot water temperature, the controller 80 calculates the required duty cycle of the water pump 30 based on its internal preset control algorithm. According to the calculated duty cycle of the water pump 30, the controller 80 controls the water pump 30 to deliver hot water to the faucet 2 at a corresponding hot water flow rate. In this way, the flow rate of the hot water matches the predetermined flow rate of the pure water, ensuring that the two waters mix at the faucet 2 to reach the user-set temperature.

[0097] Pure water from the pure water outlet pipe and hot water from the water outlet assembly 80 meet and mix thoroughly at the faucet. Because the flow rates of pure water and hot water were adjusted in the preceding steps by controlling the duty cycles of the booster pump 54 and the water pump 30, the mixing process, based on heat transfer and mixing principles, produces warm water at the set temperature. For example, at the 45℃ warm water setting, after the appropriate flow rate of pure water mixes with the corresponding flow rate of hot water, a stable 45℃ warm water temperature is ultimately output from faucet 2, thus meeting the user's needs.
