[0027] A filter assembly is installed in the filter element cavity and has a raw water inlet and a pure water outlet; and

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0056] 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.

[0057] Specifically, see Figures 1 to 3 , 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 A schematic diagram of the internal structure of a hot tank assembly provided in an embodiment of the present application.

[0058] 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.

[0059] 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 .

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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 .

[0068] 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.

[0069] 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 can be cylindrical, rectangular, etc. Exemplarily, the tank body 21 presents a long cylindrical structure with an axial dimension greater than the 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 with 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 more 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.

[0070] 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.

[0071] 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 the pre-treated external water (such as filtered pure water) 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 hot water, thereby reducing the impact on the middle and lower water layers in the heating chamber 201. The water outlet 216 can be set on the tank body 211 or the tank bottom cover 213. In one embodiment, the water outlet 216 is set on the tank body 211 and is higher than the tank bottom cover 213. By placing the water outlet 216 at a position 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 the expectations, and meet the user's demand for immediate use of hot water, such as being directly used for brewing beverages, etc., greatly improving the user's experience.

[0072] The heating element 22 of this embodiment is installed in the tank body 21, and is used to heat the water in the heating chamber 201. The heating element 22 can be a heating wire, an electric heating tube, a heating rod, etc. In one embodiment, the heating element 22 is arranged in the heating chamber 201, and the water outlet 216 at least partially overlaps with the heating element 22 in the height direction. In this way, when the water flows out from the water outlet 216, the water is already in the area that has been fully heated, ensuring that the temperature of the hot water flowing out is high.

[0073] The water pump 30 of this embodiment plays a key role in the hot water extraction process of the entire hot tank assembly 20. It can provide power for the extraction and delivery of hot water, ensuring that water can flow out of the heating chamber 201 smoothly for users to access and use.

[0074] The water inlet of the water pump 30 is connected to the water outlet 216. Exemplarily, the water outlet 216 is provided on the tank body 211, and the water inlet of the water pump 30 is connected to the water outlet 216 through a water pipe. The water pump 30 is fixed to the shell assembly 10, and the fixing method can be connected by bolts or screws; or, the shell of the water pump 30 forming the water inlet is directly connected to the tank body 211 fixed at the water outlet 216, and no water pipe is required to connect the water inlet of the water pump 30 and the water outlet 216. The drain port of the water pump 30 is connected to the hot water outlet pipe 27. In this way, the heated hot water in the heating chamber 201 can smoothly enter the hot water outlet pipe 27 under the action of the water pump 30, and then flow to the subsequent water intake link.

[0075] One end of the hot water outlet pipe 27 of this embodiment is connected to the drain port of the water pump 30, and the other end is arranged in the heating chamber 201. In particular, the hot water outlet pipe 27 is provided with a reflux port 271 which is interconnected with the heating chamber 201. When the water pump 30 extracts hot water, part of the hot water in the hot water outlet pipe 27 can flow back to the heating chamber 201 through the reflux port 271. Based on the principle of fluid mechanics, the actual lift of the water pump 30 is reduced by changing the hot water flow path. At the same time, part of the hot water outlet pipe 27 arranged in the heating chamber 201 allows the remaining water in the hot water outlet pipe 27 to be continuously in a heating environment.

[0076] In this embodiment, when the water pump 30 is working to extract hot water, the hot water flows along the hot water outlet pipe 27. Since the hot water outlet pipe 27 is provided with a reflux port 271, part of the hot water flows back to the heating chamber 201 through the reflux port 271. According to the principles of fluid mechanics, this is equivalent to reducing the actual head of the water pump 30. The reduction in head reduces the pressure difference between the water inlet 214 and the water outlet 216 of the water pump 30 accordingly. In this relatively low pressure difference environment, the gas dissolved in the water is not easy to escape in large quantities due to pressure changes to form bubbles, thereby effectively reducing the risk of air blockage in the water pump and ensuring the stability and reliability of the operation of the water pump 30.

[0077] The above-mentioned way of inserting the hot water outlet pipe 27 in the heating chamber 201 of this embodiment has many benefits. First, the hot water outlet pipe 27 is inserted into the heating chamber 201, and can be inserted from the bottom cover 213 of the tank according to the actual structural design requirements, or can be inserted from different positions of the tank body 211, and can also be inserted from the corresponding position of the tank body 211, or can be inserted from the top cover 212 of the tank. Regardless of how the specific insertion and exit positions are selected, the purpose is to allow the residual water in the hot water outlet pipe 27 to be in the heating environment in the heating chamber 201. After the user takes water, water will inevitably remain inside the hot water outlet pipe 27. If there is no reasonable treatment method, these residual water will cause the problem of low water temperature in the first cup of water when taking water next time. When the hot water outlet pipe 27 is inserted into the heating chamber 201, when the heating is started again, these residual water can be heated by the heat emitted by the heating element 22 in the heating chamber 201, and then in the case of a long interval or when taking water for the first time, the residual cold water will not be directly discharged, avoiding a bad user experience for the user. Secondly, for the cold water at the bottom of the hot tank, which is originally at a lower temperature, the heat in the heating chamber 201 can be used to fully heat the cold water with a lower temperature during the process of flowing through the heating chamber 201 through the hot water outlet pipe 27. In one embodiment, the hot water outlet pipe 27 and the heating element 22 that are inserted through the heating chamber 201 at least partially overlap in the height direction. In this way, by utilizing the partially overlapping position relationship between the hot water outlet pipe 27 and the heating element 22, the cold water flowing through the hot water outlet pipe 27 is fully heated, further improving the overall temperature of the hot water that finally flows out, ensuring that the hot water received by the user can be maintained at a relatively high and stable temperature level, meeting the needs of various hot water usage scenarios.

[0078] Furthermore, one end of the hot water outlet pipe 27 extends from the tank bottom cover 213 into the heating chamber 201 and passes through the tank top cover 212. On the one hand, since the hot water outlet pipe 27 runs through the entire heating chamber 201 from the tank bottom cover 213 to the tank top cover 212, the hot water outlet pipe 27 is longer in the heating chamber 201, and has a larger contact area with the hot water in the heating chamber 201 and the heat emitted by the heating element 22, and can absorb heat more fully. When the user takes water, the water remaining in the hot water outlet pipe 27 can be heated more comprehensively and more effectively during the next heating process, thereby better solving the problem of low temperature of the first cup of water caused by the residual water in the hot water outlet pipe 27. On the other hand, the hot water outlet pipe 27 runs through the tank body 21 in the vertical direction. Compared with some complex and circuitous waterway layouts, its vertical arrangement is more regular, which can effectively save the space inside the tank body 21 and make the overall structure of the hot tank assembly 20 more compact.

[0079] Furthermore, the tank top cover 212 is provided with an exhaust port 217, and the hot water outlet pipe 27 passes through the exhaust port 217, and there is a gap between the hot water outlet pipe 27 and the wall of the exhaust port 217. During the hot tank heating process, high-temperature steam will be generated in the tank body 21, and a discharge channel is required to maintain the pressure balance in the tank body 21 to avoid safety hazards caused by excessive pressure or affecting the normal operation of the equipment. The hot water outlet pipe 27 is passed through the exhaust port 217 with a gap, and this space is cleverly used to realize the steam discharge function. The high-temperature steam can be smoothly discharged from the tank body 21 along the gap between the hot water outlet pipe 27 and the wall of the exhaust port 217, which not only ensures the effective discharge of steam, but also does not need to set up an additional large-area exhaust channel separately, further saving the design space of the tank body 21.

[0080] See also Figure 3 , Figure 4 and Figure 5 , Figure 4 A schematic diagram of the structure of the three-way pipe 26 and the exhaust pipe 24 provided in the embodiment of the present application; Figure 5 for Figure 3 Enlarged view of point A in the middle.

[0081] In some embodiments, the hot tank assembly 20 further includes a three-way pipe 26, which has a first joint 261, a second joint 262 and a third joint 263 that are connected. The first joint 261 is directly opposite to the second joint 262, and the inner diameter of the first joint 261 is larger than the inner diameter of the second joint 262. The first joint 261 is connected to the exhaust port 217, and the hot water outlet pipe 27 passes through the first joint 261 and partially extends into the second joint 262. The partially extended hot water outlet pipe 27 is sealed and connected to the inner wall of the second joint 262. Through this sealed connection, the hot water outlet pipe 27 is connected to the second joint 262, and the first joint 261 and the second joint 262 are blocked, ensuring that the hot water can flow from the hot water outlet pipe 27 to the second joint 262 and then out according to the predetermined path, avoiding the hot water from leaking to other parts that should not appear, and ensuring the stability and accuracy of the hot water discharge.

[0082] The gap that originally existed between the hot water outlet pipe 27 and the wall of the exhaust port 217 is connected to the third joint 263 after being connected to the three-way pipe 26. In this way, the high-temperature steam generated during the hot tank heating process can enter the third joint 263 along the gap between the hot water outlet pipe 27 and the wall of the exhaust port 217, and then be smoothly discharged from the tank body 21. The design of the three-way pipe 26 effectively distinguishes the discharge paths of hot water and high-temperature steam, so that the two can be discharged separately and independently, avoiding mutual interference. It not only ensures that the temperature of the hot water received by the user is not affected by the steam, but also ensures that the high-temperature steam in the tank body 21 can be discharged in a timely and smooth manner.

[0083] Furthermore, the hot tank assembly 20 also includes an exhaust pipe 24 connected to the exhaust port 217, and the exhaust pipe 24 can be fixed to the exhaust port 217 by welding to ensure the firmness and sealing of the connection and prevent steam leakage. The first joint 261 of the three-way pipe 26 is sleeved on the exhaust pipe 24 to form a stable and reliable sleeve connection, and the gap between the hot water outlet pipe 27 and the inner wall of the exhaust pipe 24 is connected to the third joint 263 of the three-way pipe 26. In this way, the high-temperature steam generated during the hot tank heating process first flows along the gap between the hot water outlet pipe 27 and the inner wall of the exhaust pipe 24, and then is smoothly discharged from the tank body 21 through the connected third joint 263.

[0084] Please continue reading Figure 5 In one embodiment, the height of the return port 271 is not lower than the lowest position M of the exhaust pipe 24. When the return water flows out from the return port 271, the inner wall of the exhaust pipe 24 will block it, so that the return water will not directly splash onto the electrical components in the heating chamber 201, such as the water level probe, thereby effectively preventing the water level probe from short-circuiting due to water splashing, ensuring the normal operation of the water level detection function and the overall stability of the hot tank assembly 20.

[0085] Furthermore, the exhaust pipe 24 partially extends into the heating chamber 201, and this part of the structure plays a drainage role. The return water will flow vertically back to the heating chamber 201 along the exhaust pipe 24, avoiding the generation of radial water flow at the lower edge of the exhaust pipe 24. This vertical flow method effectively protects other electrical components in the heat chamber and reduces the risk of damage to electrical components due to water splashing.

[0086] In one embodiment, the height of the return port 271 is not higher than the height of the third joint 263. In this way, the return water can be prevented from splashing out from the third joint 263, thereby avoiding possible safety hazards and ensuring the reasonable flow of water inside the hot tank assembly 20 and the stable operation of the system.

[0087] See also Figure 6 and Figure 7 , Figure 6 A schematic diagram of the structure of the condenser 28 and the third joint 263 provided in the embodiment of the present application; Figure 7 Schematic diagram of the internal structure of the condenser 28 and the third joint 263 provided in an embodiment of the present application.

[0088] In some of the embodiments, the hot pot assembly 20 also includes a condenser 28, and the condenser 28 has a condensation chamber 280, and the third joint 263 is passed through the condensation chamber 280. Since the high-temperature steam generated by the hot pot during the heating process will be discharged outward through the third joint 263, and the high-temperature steam has a high temperature, it is very easy to cause scalding hazards if it is discharged directly, which brings safety risks to users. In this embodiment, by setting a condenser 28, the condensation chamber 280 inside it is used to cool the high-temperature steam flowing through the third joint 263. When the high-temperature steam enters the condensation chamber 280 through the third joint 263, 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.

[0089] 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.

[0090] 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 cooling water in the condensation chamber 280 longer and more evenly distributed, increases the contact area between cooling water and high-temperature steam, and thus improves the condensation effect. Compared with a simple parallel arrangement or other conventional arrangements, the diagonal arrangement allows cooling water to flow fully in the condensation chamber 280, more comprehensively absorbs the heat of high-temperature steam, ensures that the steam discharged from the third joint 263 is more fully cooled, and further reduces the risk of scalding.

[0091] Please continue reading Figure 3 The hot pot assembly 20 of this embodiment 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 pot top cover 212 and extend into the heating chamber 201.

[0092] 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.

[0093] Furthermore, the end of the high water level probe 233 is higher than the heating element 22, and the low water level probe 234 is lower than the highest position of the heating element 22. The above 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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 the data back to the controller.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.
