[0053] The embodiments of the present application provide a hot tank assembly and a heat and water purification integrated machine, which can reduce the risk of air blockage in the water pump of the existing heat and water purification integrated machine.

[0054] Specifically, see Figures 1 to 7 , Figure 1 A schematic diagram of the structure of a heat and air conditioning machine provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of a hot tank assembly provided in an embodiment of the present application; Figure 3 Another structural schematic diagram of the hot tank assembly provided in an embodiment of the present application; Figure 4 A schematic diagram of the structure of the hot tank assembly provided in an embodiment of the present application after the tank body is hidden; Figure 5 A schematic diagram of the structure of a hot tank assembly provided in an embodiment of the present application from a top view; Figure 6 for Figure 5 The cross-sectional view along the AA direction; Figure 7 for Figure 3 Enlarged view of point B in the middle.

[0055] The all-in-one air conditioner and heat machine of this embodiment may be a household all-in-one air conditioner and heat machine, such as an under-sink all-in-one air conditioner and heat machine.

[0056] The air conditioner and heat all-in-one machine of this embodiment includes a housing assembly 10 , a filter assembly 50 and a heat tank assembly 20 .

[0057] The shell assembly 10 serves as the external support structure of the heat and air cleaning machine, which may include an outer shell. The shape of the outer shell may be a regular geometric shape, such as a cube or a cuboid. Such regular shapes have many advantages: on the one hand, regular shapes facilitate mold making and standardized assembly of parts during the manufacturing process, which can effectively improve production efficiency and reduce production costs; on the other hand, in installation and use scenarios, the outer shell of a regular shape is easier to adapt to the surrounding environment, whether it is placed in a kitchen cabinet or other specific use location, it can be placed more neatly, save space and be beautiful.

[0058] Two chambers are formed inside the housing assembly 10, namely, a hot tank chamber 102 and a filter element chamber 101. The hot tank chamber 102 is mainly used to accommodate the hot tank assembly 20, providing a stable installation space for the hot tank assembly 20 to ensure its stability during heating, heat preservation and other working processes. The filter element chamber 101 is used to accommodate the filter assembly 50. The two chambers are relatively independent, which can avoid mutual interference between different hot tank assemblies 20 and filter assemblies 50, and also facilitate subsequent maintenance, overhaul or replacement of each assembly.

[0059] The shell assembly 10 serves as the external support and protection structure of the entire hot tank assembly 20. In addition to having functional partitions such as the hot tank chamber 102 and the filter element chamber 101, it also has a heat dissipation function in this embodiment to ensure that the internal hot tank assembly 20 and other components can be stably installed and operate under normal temperature conditions.

[0060] Exemplarily, the housing assembly 10 also has an air inlet 1021 and an air outlet 1022 respectively connected to the hot tank cavity 102, and the air inlet 1021, the hot tank cavity 102 and the air outlet 1022 together constitute a cooling air duct. The air inlet 1021 is arranged at the bottom of the outer housing, and the air inlet 1021 is connected to the bottom of the hot tank cavity 102, so that the cold air from the outside can smoothly enter the area where the hot tank cavity 102 is located from the bottom of the device. The air outlet 1022 is arranged at the top of the outer housing, and is connected to the top of the hot tank cavity 102, so that the hot air generated by the hot tank assembly 20 during operation is discharged from the air outlet 1022 at the top under the action of thermal buoyancy and the like. The layout of the entire cooling air duct forms a heat convection channel. Cold air enters from the bottom air inlet 1021, flows through the hot tank assembly 20, absorbs heat and becomes hot air, and is then discharged from the top exhaust port 1022, thereby effectively taking away the heat emitted by the hot tank assembly 20, maintaining the hot tank assembly 20 and its surrounding environment within a relatively suitable temperature range, and ensuring the normal operation of the equipment.

[0061] The filter assembly 50 of this embodiment is installed in the filter element cavity 101. The filter assembly 50 is provided with a raw water inlet and a pure water outlet. The raw water inlet can be directly connected to the external tap water supply pipeline, and is the entrance for tap water to enter the purifier and heat all-in-one machine for filtering. The pure water outlet is connected to the water inlet 214 of the hot tank assembly 20, so that the filtered pure water can smoothly flow into the hot tank assembly 20 for subsequent heating or heat preservation operations, or directly be taken by the user through the faucet.

[0062] The filter assembly 50 in this embodiment has a multi-stage filtering function, which may include PAC (polyaluminium chloride) filtration and RO (reverse osmosis) filtration. PAC filtration is a pre-filtration link. By utilizing the flocculation effect of PAC, impurities such as suspended particles and colloids in tap water can be aggregated into larger flocs, which are convenient for subsequent filtration and removal. PAC filtration can effectively intercept large impurities such as silt and rust in water, reduce the burden of subsequent RO filtration, and extend the service life of the RO membrane.

[0063] RO filtration is the core of the entire filtration process. The RO reverse osmosis membrane has an extremely small pore size. Under pressure, it can only allow water molecules to pass through, while intercepting most impurities such as bacteria, viruses, heavy metal ions, etc. in the water, thereby obtaining extremely pure water. Through the synergistic effect of these two levels of filtration, it is ensured that the water flowing out of the pure water outlet of the filter component 50 reaches a very high purity, meeting the user's requirements for healthy and high-quality drinking water.

[0064] During the filtering process, due to the filtering characteristics of the RO reverse osmosis membrane, a small amount of waste water will be generated after the tap water is filtered, and the waste water is discharged through the waste water outlet provided on the filtering component 50 .

[0065] The hot tank assembly 20 in this embodiment is a key part of the heat and water purification integrated machine, which can reduce the risk of air blockage in the water pump.

[0066] Specifically, the hot tank assembly 20 includes a tank body 21, a heating element 22, a water pump 30 and a hot water outlet pipe 27. Among them, the tank body 21 can be cylindrical, rectangular, etc. Exemplarily, the tank body 21 presents a long cylindrical structure with an axial dimension greater than a radial dimension. The design of the long cylindrical tank body 21 has many advantages. From the perspective of space utilization, it has a certain extension length in the vertical direction, and can increase the internal water storage volume on the basis of a limited plane footprint, thereby meeting a certain amount of hot water supply demand, and is suitable for application in various types of equipment that have certain requirements for space layout, such as a heat and water purifier installed in a kitchen cabinet. From the perspective of heat transfer, the long cylindrical structure allows water to form a relatively stable stratification in the tank body 21, which is conducive to a relatively uniform conduction of heat in the vertical direction. Compared with some irregularly shaped or short and thick tank body 21 structures, it can reduce local heat accumulation or heat transfer dead corners.

[0067] Furthermore, the can body 21 includes a can body 211, a can top cover 212 and a can bottom cover 213. The height dimension of the can body 211 is greater than its width dimension. The can body 211 is connected to the can top cover 212 and the can bottom cover 213 respectively, and the three together enclose a heating chamber 201. Among them, the can body 211 constitutes the side of the can body 21, the can top cover 212 constitutes the top of the can body 21, and the can bottom cover 213 constitutes the bottom of the can body 21. Among the can body 211, the can top cover 212 and the can bottom cover 213, the three components can be processed separately by using appropriate processes. For example, the can body 211 can be formed by a rolling process, and the can top cover 212 and the can bottom cover 213 can be made by stamping and other processes, and then sealed and connected, which not only ensures the overall structural strength of the can body 21, but also improves efficiency and reduces costs during the production process.

[0068] The tank body 21 is provided with a water inlet 214 and a water outlet 216 respectively connected to the heating chamber 201. The water inlet 214 is used to introduce pre-treated water (such as filtered pure water) from the outside into the heating chamber 201, and its position can be set on the tank top cover 212 to ensure that the incoming water is first distributed in the upper layer of the hot water, thereby reducing the impact on the middle and lower water layers in the heating chamber 201. The water outlet 216 is set on the side of the tank body 21, that is, the water outlet 216 is set on the tank body 211.

[0069] The heating element 22 is installed on the tank body 21, and can be installed on the tank body 211, the tank top cover 212, etc. The heating element 22 is used to heat the water in the heating chamber 201. The heating element 22 can be in various forms, such as common resistance heating wires, electric heating tubes, etc.

[0070] The water pump 30 is connected to the water outlet 216 of the tank body 21, and is mainly used to provide power for the flow of water in the hot tank assembly 20. When the hot tank assembly 20 is working, the water pump 30 is started to pump out the hot water in the heating chamber 201 from the water outlet 216, and transport it to the hot water outlet pipe 27 through the water pumping port, thereby realizing the transportation of hot water.

[0071] The hot water outlet pipe 27 of this embodiment is a key component for solving the problem of air blockage of the water pump 30. Specifically, the hot water outlet pipe 27 includes an outlet pipe 271, one end of which is connected to the water inlet of the water pump 30, and the other end is connected to the water outlet 216. The inner diameter of the outlet pipe 271 of this embodiment is designed to increase in the direction from the water inlet of the water pump 30 toward the water outlet 216 of the tank body 21, that is, the inner wall of the upper part of the outlet pipe 271 presents an inclined shape rising toward the heating chamber 201. The increase in inner diameter can be a step-like increase, that is, the inner diameter of the pipe increases in a step-like form at different positions; it can also be a continuous gradual increase, that is, the inner diameter of the pipe gradually and continuously increases from the water inlet of the water pump 30 to the water outlet. This method makes the transition of water flow in the outlet pipe 271 smoother and reduces the turbulence and resistance of the water flow. The inner diameter design of the outlet pipe 271 is the key to solving the problem of air blockage of the water pump 30 in the hot tank assembly 20. When the water pump 30 starts to extract hot water, the gas dissolved in the water escapes due to pressure changes to form bubbles. In the traditional pipeline structure, these bubbles are easy to gather at the water pumping port, thereby causing air blockage. In the present hot tank assembly 20, since the inner diameter of the water outlet pipe 271 is increased along the direction from the water pumping port of the water pump 30 to the water outlet 216 of the tank body 21, the inner wall is inclined upward, and the bubbles generated at the water pumping port during the water pumping process of the water pump 30 will be guided by the inclined direction of the inner wall and float upward along the inner wall. As the bubbles float up, they will eventually enter the heating chamber 201. In this way, the gathering of bubbles at the water pumping port is effectively avoided, thereby greatly reducing the risk of air blockage caused by the water pump 30, ensuring that the water pump 30 can work continuously and stably, and ensuring the normal operation of the hot tank assembly 20.

[0072] Furthermore, the inner wall of the water outlet pipe 271 is partially inclined upward in the direction from the water outlet of the water pump 30 toward the water outlet 216. When the water pump 30 is started and hot water is extracted, the gas dissolved in the water will escape and form bubbles under the pressure change. Due to the inclined design of the inner wall of the water outlet pipe 271, these bubbles will float upward along the inclined inner wall. In this way, the buoyancy of the bubbles and the flow characteristics of the water are utilized to guide the bubbles to move upward. Compared with the traditional horizontal or vertical inner wall, the inclined inner wall provides a natural rising channel for the bubbles, so that the bubbles can leave the water outlet area of ​​the water pump 30 more smoothly, avoiding the bubbles from gathering at the water outlet, thereby effectively reducing the risk of air blockage in the water pump 30.

[0073] In some embodiments, the central axis of the water outlet pipe 271 is perpendicular to the central axis of the tank body 211. This vertical relationship helps to optimize the layout of the hot water outlet pipe 27 in the tank body 21, so that the hot water outlet pipe 27 is more reasonable when it cooperates with the tank body 211. On the one hand, the vertical arrangement can facilitate the installation of the water pump 30; on the other hand, this layout is conducive to the flow of water in the water outlet pipe 271, reducing water flow turbulence and energy loss caused by unreasonable structural layout, and improving the efficiency of hot water transportation. It can be understood that in the actual manufacturing or installation process, due to the existence of human errors, even if there is a certain deviation in the vertical relationship between the central axis of the water outlet pipe 271 and the central axis of the tank body 211, as long as it is within a reasonable tolerance range (for example, a deviation of ±5°), they can still be considered perpendicular to each other.

[0074] In one embodiment, the water outlet 216 is at a preset distance from the tank bottom cover 213, and the preset distance is not less than 5 mm. In this way, water is avoided from being taken directly from the bottom of the hot tank, because the water at the bottom of the hot tank is usually at a lower temperature in the early stage of heating. By placing the water outlet 216 at a position at least 5 mm higher than the tank bottom cover 213, the water flowing out of the heating chamber 201 comes from a relatively high temperature area, thereby solving the problem of low temperature of the first cup of water, ensuring that the temperature of the first cup of water received by the user can meet expectations, and satisfying the user's demand for immediate use of hot water.

[0075] In one embodiment, the heating element 22 is disposed in the heating chamber 201 and extends toward the tank bottom cover 213 without contacting the tank bottom cover 213. During the heating process of the hot tank, the traditional heating method may cause the water at the bottom of the hot tank to heat up too slowly, because the heat needs to be gradually transferred downward from the location of the heating element 22 to the water at the bottom of the tank, the distance is far and there is a certain time delay in the heat transfer. In this embodiment, the heating element 22 is disposed close to the tank bottom cover 213, which can make the heat transfer to the water at the bottom of the hot tank more directly and quickly, significantly accelerating the heating speed of this part of the water.

[0076] like Figure 2 and Figure 4As shown, the heating element 22 is arranged in a spiral shape, and the two ends of the spiral heating element 22 are parallel to each other, and the two ends extend out of the tank body 211 and are installed on the same busbar L of the tank body 211. The two ends can be connected to the wiring terminals respectively to realize the power-on function, provide electric energy to the heating element 22 to generate heat, and then heat the water in the heating chamber 201. The two ends extend out in parallel with each other and are installed on the same busbar L of the tank body 211, which means that they are located on a vertical plane. Such a design has many benefits: first, the bottom of the spiral heating element 22 tends to be close to the plane, so that the heating element 22 can be arranged as close to the tank bottom cover 213 as possible. Because when the bottom is close to the plane, the distance between the heating element 22 and the tank bottom cover 213 can be more evenly and stably close to the water at the bottom of the tank under the premise of ensuring non-contact, so that the heat can be transferred to the water at the bottom of the tank more efficiently, speeding up the heating speed of the water at the bottom of the hot tank, solving the problem of slow heating of the bottom water in the traditional design, and further ensuring the uniformity of the overall heating of the water in the hot tank. Secondly, the two ends are located on the same busbar L, which facilitates the installation process of the heating element 22 on the tank body 211. During the production and assembly process, the operator can fix the heating element 22 on the tank body 211 more conveniently and accurately based on the installation position requirements of this clear rule, thereby improving production efficiency and helping to ensure the stability of the installation of the heating element 22.

[0077] Furthermore, the water outlet 216 at least partially overlaps with the heating element 22 in the height direction. In this way, when water flows out of the water outlet 216, the water is already in a fully heated area, ensuring that the temperature of the hot water flowing out is high.

[0078] Furthermore, the spiral center line of the heating element 22 coincides with the central axis of the tank body 211. When the spiral center line of the heating element 22 coincides with the central axis of the tank body 211, the heat generated by the heating element 22 can be evenly dissipated to the surrounding water around the center of the tank body 211. In this way, the water at each position in the hot tank can receive the same amount of heat in a similar time, avoiding the situation where the local water temperature is too high or too low due to uneven heating.

[0079] In one embodiment, please continue to see Figure 2 and Figure 3 The hot water outlet pipe 27 further includes a drain pipe 272, which is connected to the drain port of the water pump 30. The drain pipe 272 is also connected to a return branch pipe 273, one end of which is connected to the drain pipe 272, and the other end of which is connected to the heating chamber 201. Exemplarily, the return branch pipe 273 is connected to the tank top cover 212 and connected to the heating chamber 201.

[0080] In this embodiment, when the water pump 30 extracts hot water, the drain pipe 272 discharges the hot water, and at the same time, part of the hot water flows back to the heating chamber 201 through the reflux branch pipe 273, so that the hot water forms a cycle during the flow process, thereby improving the utilization efficiency of the hot water.

[0081] The reflux branch pipe 273 of this embodiment is a key part of the hot water outlet pipe 27, and the reflux branch pipe 273 plays an important role in reflux. When the water pump 30 is working, part of the hot water in the drain pipe 272 can flow back to the heating chamber 201 through the reflux branch pipe 273. According to the principles of fluid mechanics, the reflux of part of the hot water reduces the actual head of the water pump 30, thereby reducing the pressure difference between the water inlet 214 and the water outlet 216 of the water pump 30. In a lower pressure difference environment, the gas dissolved in the water is not easy to escape in large quantities due to pressure changes to form bubbles, which effectively reduces the risk of gas blockage in the water pump 30.

[0082] When the hot tank assembly 20 starts working, the external water source enters the heating chamber 201 through the water inlet 214 of the tank body 21, and the heating element 22 heats the water. After the water pump 30 is started, on the one hand, the hot water in the heating chamber 201 is pumped out from the water outlet 216, and the hot water supply or other subsequent operations are carried out through the drain pipe 272; on the other hand, part of the hot water flows back to the heating chamber 201 through the reflux branch pipe 273. The hot water reflux design reduces the actual head of the water pump 30 and reduces the pressure difference between the water inlet 214 and the water outlet 216 of the water pump 30. According to the principles of fluid mechanics, the lower pressure difference environment inhibits the escape of dissolved gas in the water, thereby avoiding the formation of a large number of bubbles and reducing the risk of air blockage in the water pump 30. At the same time, the reflux of hot water also helps to maintain the uniformity of water temperature in the heating chamber 201 and improve the overall utilization efficiency of hot water.

[0083] In one embodiment, please continue to see Figure 3 and Figure 6 The hot tank assembly 20 further includes a detection assembly 23 for detecting the water level of the heating chamber 201, and the detection assembly 23 includes a high water level probe 233 and a low water level probe 234. The high water level probe 233 and the low water level probe 234 are spaced apart on the tank top cover 212 and extend into the heating chamber 201.

[0084] The arrangement of the high water level probe 233 and the low water level probe 234 on the tank top cover 212 at intervals and relatively independently is of great significance. In a humid environment, water easily forms a water film on the surface of an object. If the distance between the probes is too close or the layout is unreasonable, the water film may cause a short circuit between the two probes, thereby affecting the accuracy and reliability of water level detection. By arranging the probes independently at intervals, it is possible to effectively avoid the water film from forming a conductive path between the two probes, ensuring that they can each accurately detect water level changes, thereby improving the accuracy and stability of water level detection.

[0085] Furthermore, the end of the high water level probe 233 is higher than the heater 22, and the low water level probe 234 is lower than the highest position N of the heater 22. The highest position N of the heater 22 refers to the position of the end surface of the heater 22 close to the tank top cover 212.

[0086] The above-mentioned position design is mainly used to prevent the hot pot assembly 20 from dry burning. When the water level rises to the position of the high water level probe 233, it indicates that the water in the heating chamber 201 has reached a higher water level. At this time, the control system can reasonably control the water inlet operation according to the signal fed back by the high water level probe 233 to avoid excessive water overflow. When the water level drops to the position of the low water level probe 234, it means that the amount of water in the heating chamber 201 is already at a low level, close to the critical state that may cause the heating element 22 to dry burn. At this time, the low water level probe 234 will send a signal to the control system in time. After receiving the signal, the control system will immediately stop the heating work of the heating element 22, thereby effectively preventing the heating element 22 from dry burning without water coverage, protecting the safety of the heating element 22 and the entire hot pot assembly 20.

[0087] In one embodiment, see Figure 3 , Figure 8 and Fig. 9 , Figure 8 A schematic diagram of the structure of the exhaust pipe and the condenser provided in the embodiment of the present application; Fig. 9 A schematic diagram of the internal structure of the exhaust pipe and the condenser provided in an embodiment of the present application.

[0088] The hot tank assembly 20 also includes an exhaust pipe 24 and a condenser pipe 28. The exhaust pipe 24 is connected to the tank top cover 212 and communicates with the heating chamber. During the hot tank heating process, high-temperature steam is generated in the tank body 21, and the high-temperature steam is discharged through the exhaust pipe 24 to maintain the pressure balance in the tank body 21, avoiding safety hazards caused by excessive pressure or affecting the normal operation of the equipment.

[0089] The condenser 28 of this embodiment has a condensation chamber 280, and the exhaust pipe 24 is arranged in the condensation chamber 280. Since the high-temperature steam generated by the hot tank during the heating process will be discharged outward through the exhaust pipe 24, and the high-temperature steam has a high temperature, it is very easy to cause scalding hazards if it is directly discharged, which brings safety risks to users. In this embodiment, by setting up the condenser 28, the condensation chamber 280 inside it is used to cool the high-temperature steam flowing through the exhaust pipe 24. When the high-temperature steam enters the condensation chamber 280 through the exhaust pipe 24, it exchanges heat with the cooling water in the condensation chamber 280, and the heat is transferred out, so that the steam temperature can be reduced, effectively avoiding the scalding problem that may be caused by the direct discharge of high-temperature steam, and greatly improving the safety of the use of the equipment.

[0090] Furthermore, the condenser 28 also has an inlet joint 281 and an outlet joint 282 respectively connected to the condensing chamber 280, and the outlet joint 282 is connected to the water inlet 214 of the tank body 21. The cooling water can be pure water filtered from the filter assembly 50. This method of using filtered pure water as cooling water not only ensures the purity of the cooling water and avoids contamination inside the equipment, but also makes full use of the existing resources of the equipment itself. Pure water enters the condensing chamber 280 from the inlet joint 281, exchanges heat with high-temperature steam in the condensing chamber 280, absorbs the heat of the steam, and then flows out from the outlet joint 282, and then enters the heating chamber 201 through the water inlet 214. In this way, the heat of the high-temperature steam is utilized to a certain extent, and the energy utilization efficiency of the entire equipment is improved.

[0091] Furthermore, the water outlet joint 282 is higher than the water inlet joint 281, and the water inlet joint 281 and the water outlet joint 282 are arranged roughly diagonally. This layout makes the flow path of the cooling water in the condensation chamber 280 longer and more evenly distributed, increases the contact area between the cooling water and the high-temperature steam, and thus improves the condensation effect. Compared with a simple parallel arrangement or other conventional arrangements, the diagonal arrangement allows the cooling water to flow fully in the condensation chamber 280, more comprehensively absorbs the heat of the high-temperature steam, ensures that the steam discharged from the exhaust pipe 24 is more fully cooled, and further reduces the risk of scalding.

[0092] In some of the embodiments, the air conditioner and heat all-in-one machine of this embodiment can also enable the user to obtain the set water temperature.

[0093] Specifically, the filter assembly 50 of this embodiment also includes a pure water outlet pipe, one end of which is connected to the pure water outlet of the RO filter element, and the other end has two branches, one branch transports pure water to the heating chamber 201, and the other branch transports pure water to the booster pump and the faucet, and intersects with the hot water outlet pipe 27 at the faucet.

[0094] The air conditioner and heat all-in-one machine also includes a booster pump, a faucet, a first temperature sensor, a second temperature sensor and a controller.

[0095] Among them, the booster pump is connected to the pure water outlet pipe, and controls the operating power by adjusting its own duty cycle, thereby outputting different pure water flow rates. The duty cycle can be determined by the warm water gear selected by the user.

[0096] The faucet is used as a water use terminal to receive pure water from the pure water outlet pipe and hot water from the hot water outlet pipe 27, and mix the two to form warm water of a set temperature.

[0097] The first temperature sensor can be installed in the tank body 21 or in the hot water outlet pipe 27 to monitor the temperature of the hot water in the heating chamber 201 and feed the data back to the controller.

[0098] The second temperature sensor is installed on the pure water outlet pipe to detect the pure water temperature in the pure water outlet pipe and feed back the data to the controller.

[0099] The controller is used to receive data from the first temperature sensor and the second temperature sensor, and based on the temperature data, control the operating power of the water pump 30 and the booster pump, so as to adjust the flow of hot water and pure water, and finally form water with a user-set temperature value at the faucet. In this embodiment, the controller controls the operating power of the water pump 30 and the booster pump by controlling their duty cycle.

[0100] For example, the user selects a specific warm water level on the operating interface of the air conditioner and heat machine according to the water temperature requirement, such as the common 45°C or 55°C.

[0101] When the user selects the warm water gear, the controller will control the duty cycle of the booster pump according to the preset corresponding relationship. For example, when the user selects the 45℃ warm water gear, the duty cycle of the booster pump is set to 85%; if the 55℃ warm water gear is selected, the duty cycle of the booster pump is set to 75%. Through this duty cycle adjustment, the booster pump can deliver pure water to the faucet at a corresponding pure water flow rate. The adjustment of the duty cycle is actually controlling the working time ratio of the booster pump, and then controlling the flow rate of pure water, ensuring that an appropriate amount of low-temperature pure water is involved in the mixing process.

[0102] When the booster pump starts to deliver pure water, the first temperature sensor continuously monitors the temperature of the hot water in the heating chamber 201, and the second temperature sensor synchronously detects the temperature of the pure water in the pure water outlet pipe. The two temperature sensors obtain temperature data in real time and transmit it to the controller to provide temperature data for the subsequent calculation and control of the duty cycle of the water pump 30.

[0103] After receiving the detection values ​​of the pure water temperature and the hot water temperature, the controller calculates the duty cycle required by the water pump 30 according to the internal preset control algorithm. According to the calculated duty cycle of the water pump 30, the controller controls the water pump 30 so that the water pump 30 delivers hot water to the faucet at the corresponding hot water flow rate. In this way, the flow rate of hot water can match the determined pure water flow rate, so that the two can reach the user-set temperature after mixing at the faucet.

[0104] The pure water delivered from the pure water outlet pipe and the hot water delivered from the hot water outlet pipe 27 meet at the faucet and are fully mixed. Since in the previous steps, the flow rates of pure water and hot water are adjusted by controlling the duty cycle of the booster pump and the water pump 30, the two can form warm water of the set temperature according to the heat transfer and mixing principle when mixed. For example, at the 45°C warm water gear, after the pure water of the appropriate flow rate is mixed with the hot water of the corresponding flow rate, warm water with a temperature of 45°C is finally stably output at the faucet, thereby meeting the needs of users.

[0105] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
