Description

Technical Field

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

[0002] Integrated water purifiers and heaters, providing both room-temperature and heated purified water, are gaining popularity and becoming an indispensable household appliance. These units consist of a filter and a heating element. The filter directly outputs purified water from the tap water source, or the heating element heats the water before outputting it, allowing for either room-temperature or hot water when connected to a tap. However, traditional integrated water purifiers have some drawbacks: the heating element heats water to temperatures below boiling (45℃, 60℃, 70℃, etc.), leaving insufficient heat to kill bacteria and microorganisms, resulting in harder water; while the heating element can boil the water, users need to wait for it to cool naturally, which takes too long and makes it difficult to control the temperature, impacting the user experience; and because the heating element needs to heat water to the desired temperature quickly, the limited volume of water that can be heated in a short time results in a smaller water supply.

[0003] To address these issues, integrated water purifiers and heat exchangers with heat exchange devices have emerged. These devices exchange heat between boiling water and room temperature water, cooling the water to approximately 45°C (low-temperature boiled water) or 50°C-90°C (medium-high temperature boiled water). This cooled water undergoes a sterilization process through the instant heating element, resulting in softer, healthier, and more suitable drinking water. Currently, there are two main types of integrated water purifiers and heat exchangers with heat exchange devices: The first type has two hot water exchange paths: one for room temperature water and the other for boiling water heated by the instant heating element, allowing for rapid cooling. The second type also has two hot water exchange paths: one for a high-temperature liquid medium and the other for room temperature water, allowing for heat exchange between the two. The room temperature water is preheated before entering the instant heating element, thus improving heating efficiency and increasing water supply. However, the heat exchange devices of the two types of integrated water purifiers can only form one heat exchange system. Based on this, the first type of integrated water purifier can only quickly prepare cooled boiled water through the heat exchange device, while the second type can only preheat room temperature water through the heat exchange device. This makes the heat exchange function of the integrated water purifier singular and unable to meet the two heat exchange needs at the same time, thus failing to meet people's growing usage needs. Utility Model Content

[0004] This application provides a water circuit structure for an integrated water purifier and heater to improve or solve the technical problems of existing integrated water purifiers and heaters being unable to produce cooled boiled water and having a small hot water supply.

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

[0006] A water circuit structure for an integrated water purifier and heat pump includes a filter element, an instant heating element, a heat exchange module, and an energy storage module. The heat exchange module has a cooling water circuit, a pure water circuit, and a medium water circuit. The cooling water circuit and the medium water circuit are respectively capable of heat exchange with the pure water circuit. The energy storage module includes an energy storage tank for storing liquid energy storage medium and a heating structure for heating the liquid energy storage medium. The pure water outlet of the filter element is connected to the pure water circuit, the pure water circuit is connected to the inlet of the instant heating element, the outlet of the instant heating element is connected to the cooling water circuit and the hot water outlet of the integrated water purifier and heat pump, and the cooling water circuit is connected to the hot water outlet. The liquid energy storage medium in the energy storage tank can flow back to the energy storage tank after passing through the medium water circuit.

[0007] The water circuit structure of the integrated water purifier and heat pump provided in this application also includes the following additional technical features:

[0008] The cooling water circuit is nested within the pure water circuit, and the pure water circuit is nested within the medium water circuit; or, the medium water circuit is nested within the pure water circuit, and the pure water circuit is nested within the cooling water circuit.

[0009] The inlet of the cooling water path is close to the outlet of the pure water path, and the outlet of the cooling water path is close to the inlet of the pure water path, so that the water flow direction in the cooling water path is opposite to the water flow direction in the pure water path.

[0010] The energy storage tank is provided with a medium outlet for supplying liquid energy storage medium to the medium water path and a medium inlet for the liquid energy storage medium to flow back from the medium water path. The medium outlet is positioned higher than the medium inlet on the energy storage tank.

[0011] The energy storage tank is equipped with a medium supply port. The pure water outlet is connected to the medium supply port through a water supply valve, so that the pure water filtered by the filter element can be transported into the energy storage tank to form a liquid energy storage medium.

[0012] The energy storage tank is equipped with a water level detection module for detecting the water level of the liquid energy storage medium. The water level detection module includes a high water level detection sensor and a low water level detection sensor. When the high water level detection sensor detects the target water level, the water supply valve closes, causing the filter element to stop supplying water to the energy storage tank. When the low water level detection sensor detects the target water level, the water supply valve opens, allowing the filter element to supply water to the energy storage tank.

[0013] The energy storage tank stores liquid energy storage medium through a sealable energy storage cavity. The energy storage tank is equipped with a medium filling port for injecting liquid energy storage medium into the energy storage cavity and a control valve that can open or close the medium filling port. The water circuit structure also includes a pressure relief channel for releasing pressure from the energy storage cavity to the outside. A pressure relief valve is provided on the fluid path of the pressure relief channel.

[0014] The water circuit structure includes a mixing pipe for discharging water to the hot water outlet. The cooling water circuit and the instantaneous heating element are both connected to the hot water outlet through the mixing pipe, so that the water discharged from the instantaneous heating element and the water discharged from the cooling water circuit can be mixed in the mixing pipe and then flow to the hot water outlet.

[0015] The water circuit structure includes a proportional regulating valve, the outlet of which is connected to the mixing pipe, and the cooling water circuit and the instant heating element are respectively connected to the two inlets of the proportional regulating valve, so as to regulate the water supply flow rate to the mixing pipe through the proportional regulating valve.

[0016] The instantaneous heating element is connected to the mixing pipe via a hot water pump, and the cooling water path is connected to the mixing pipe via a warm water pump.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application include at least the following:

[0018] 1. The water circuit structure of the integrated water purifier and heater provided in this application involves the purified water filtered by the filter element being transported to the instant heating element via a pure water circuit. The water heated by the instant heating element has two output paths: one is directly transported to the hot water outlet, and the other is transported to the hot water outlet via a cooling water circuit. Therefore, based on the heat exchange capability between the cooling water circuit and the pure water circuit, boiling water heated by the instant heating element can be transported to the cooling water circuit. This allows the boiling water in the cooling water circuit to exchange heat with the room-temperature water in the pure water circuit. On one hand, the boiling water in the cooling water circuit can be quickly cooled to become cooled boiled water, allowing users to quickly obtain cooled boiled water and shortening the waiting time. On the other hand, through heat exchange, the water in the pure water circuit is preheated, shortening the heating time required for the instant heating element to reach boiling point, thus saving energy consumption of the instant heating element. The energy storage tank and the medium water circuit form a circulation loop. The liquid energy storage medium in the energy storage tank can flow back into the energy storage tank through the medium water path, and the medium water path can exchange heat with the pure water path. This allows the liquid energy storage medium in the energy storage tank to be preheated before being transported to the medium water path, where it transfers heat to the pure water path. Therefore, when the filter element supplies water to the instant heating element through the pure water path, the room temperature water in the pure water path can exchange heat with the liquid energy storage medium in the medium water path, allowing the room temperature water in the pure water path to be preheated quickly before being transported to the instant heating element for rapid heating to boiling water. This significantly shortens the time required for the instant heating element to heat the water to boiling. Boiling water can be directly delivered to the hot water outlet, effectively improving the water output response speed and water volume of the integrated water purifier and heat pump. This not only shortens the waiting time for users to get hot water but also helps save energy.

[0019] 2. As a preferred method, the cooling water circuit is nested within the pure water circuit, and the pure water circuit is nested within the medium water circuit, forming a nested heat exchange. The water flow in the pure water circuit fully surrounds and contacts the outer wall of the cooling water circuit, and the liquid energy storage medium in the medium water circuit fully surrounds and contacts the outer wall of the pure water circuit. This helps to improve the heat exchange efficiency of the heat exchange module, shorten the heat exchange time, and enable the integrated water purifier and heat pump to quickly meet the user's selected outlet water temperature requirements.

[0020] 3. As a preferred method, the water flow direction in the cooling water circuit is opposite to that in the pure water circuit. When the hot water of the instantaneous heat source is delivered to the cooling water circuit, the hot water in the cooling water circuit and the room temperature water in the pure water circuit flow in opposite directions to exchange heat. This can maximize the use of the temperature difference between hot and cold water, so as to achieve the effect of higher temperature rise of room temperature water and lower temperature drop of boiling water.

[0021] 4. As a preferred method, the medium outlet is positioned higher than the medium inlet on the energy storage tank. This facilitates the circulation of hot water between the energy storage tank and the medium water circuit, ensuring that the liquid energy storage medium supplied from the energy storage tank to the medium water circuit is predominantly high-temperature liquid energy storage medium. Consequently, during heat exchange between the medium water circuit and the pure water circuit, the liquid energy storage medium can transfer more and faster heat to the room-temperature water in the pure water circuit, resulting in a higher temperature rise and a larger water volume.

[0022] 5. As a preferred method, the pure water filtered by the filter element is transported to the energy storage tank to form a liquid energy storage medium. Water has a large specific heat capacity and thermal conductivity. Using water as a liquid energy storage medium can store more heat and can transfer heat from the medium water circuit to the pure water circuit more quickly, thereby improving heat exchange efficiency.

[0023] 6. As a preferred method, the energy storage tank stores liquid energy storage medium through a sealed energy storage chamber. It is preferable to use liquid energy storage medium with a higher boiling point (such as heat transfer oil) for energy storage. The energy storage temperature is heated to a higher level (generally ≥100℃) by the heating structure, so that the liquid energy storage medium stores more heat energy. This results in a greater temperature difference between the liquid energy storage medium and the room temperature water to be heated in the pure water circuit, thereby obtaining higher heat exchange efficiency. As a result, the water temperature after heat exchange in the pure water circuit is higher, and the hot water output flow rate is larger.

[0024] 7. As a preferred method, the water discharged from the instantaneous heating element and the water discharged from the cooling water circuit can be mixed in the mixing pipe and then flow to the hot water outlet, which facilitates water temperature regulation. For example, the instantaneous heating element can discharge boiling water into the mixing pipe and the cooling water circuit at the same time. The boiling water in the cooling water circuit exchanges heat with the room temperature water in the pure water circuit to form cooled boiled water, and then mixes it with the boiling water directly delivered to the mixing pipe by the instantaneous heating element in proportion, so as to obtain cooled boiled water at different temperatures.

[0037] In the embodiments of this application, a water circuit structure for an integrated water purifier and heat pump is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0038] like Figure 1 and Figure 2 As shown, the water circuit structure of the integrated water purifier and heat pump provided in this application includes a filter element 10, an instant heating element 11, a heat exchange module, and an energy storage module. The heat exchange module is provided with a cooling water circuit 12, a pure water circuit 13, and a medium water circuit 14. The cooling water circuit 12 and the medium water circuit 14 can exchange heat with the pure water circuit 13. The energy storage module includes an energy storage tank 15 for storing liquid energy storage medium and a heating structure 16 for heating the liquid energy storage medium. The pure water outlet of the filter element 10 is connected to the pure water circuit 13. The pure water circuit 13 is connected to the inlet of the instant heating element 11. The outlet of the instant heating element 11 is connected to the cooling water circuit 12 and the hot water outlet 18 of the integrated water purifier and heat pump. The cooling water circuit 12 is connected to the hot water outlet 18. The liquid energy storage medium in the energy storage tank 15 can flow back to the energy storage tank 15 after passing through the medium water circuit 14. Specifically, the pure water outlet of the filter element 10 can be connected to the pure water channel 13 through the pure water pump 17, and the liquid energy storage medium in the energy storage tank 15 can be extracted by the medium pump 19 and transported to the medium channel 14 before flowing back into the energy storage tank 15.

[0039] The water circuit structure of the integrated water purifier and heat exchanger in this application includes a heat exchange module and an energy storage module. The cooling water circuit 12 of the heat exchange module can exchange heat with the pure water circuit 13, and the pure water circuit 13 can also exchange heat with the medium water circuit 14. The liquid energy storage medium stored in the energy storage tank 15 can be heated to a high temperature by the heating structure 16 to achieve energy storage. The pure water outlet of the filter element 10 is connected to the pure water circuit 13 through the pure water pump 17, and is connected to the inlet of the instantaneous heating element 11 through the pure water circuit 13, so that the pure water filtered by the filter element 10 can be transported to the instantaneous heating element 11 through the pure water circuit 13 under the operation of the pure water pump 17. The outlet of the instant heating element 11 is connected to the cooling water path 12 and the hot water outlet 18. The cooling water path 12 is connected to the hot water outlet 18, so that the water heated by the instant heating element 11 has two output paths: one is directly delivered to the hot water outlet 18, and the other is delivered to the hot water outlet 18 through the cooling water path 12. Therefore, based on the fact that the cooling water path 12 and the pure water path 13 can exchange heat, the boiling water heated by the instant heating element 11 can be delivered to the cooling water path 12, so that the boiling water in the cooling water path 12 can exchange heat with the room temperature water in the pure water path 13. On the one hand, the boiling water in the cooling water path 12 can be quickly cooled to form cool boiled water, so that users can quickly obtain cool boiled water and shorten the waiting time. On the other hand, through heat exchange, the water in the pure water path 13 is preheated and heated, which can shorten the heating time for entering the instant heating element 11 to be heated to boiling water, thus saving energy consumption of the instant heating element 11. The energy storage tank 15, the medium water channel 14, and the medium pump 19 are connected in series. The energy storage tank 15 and the medium water channel 14 form a circulation loop. The liquid energy storage medium in the energy storage tank 15 can be pumped to the medium water channel 14 by the medium pump 19 and then flow back to the energy storage tank 15. The medium water channel 14 can exchange heat with the pure water channel 13, allowing the liquid energy storage medium in the energy storage tank 15 to be preheated before being transported to the medium water channel. This allows the liquid energy storage medium to transfer heat to the pure water channel 13. Therefore, in When the filter element 10 supplies water to the instant heating element 11 through the pure water circuit 13, it can use the room temperature water in the pure water circuit 13 to exchange heat with the liquid energy storage medium in the medium water circuit 14, so that the room temperature water in the pure water circuit 13 can be rapidly heated and preheated before being sent to the instant heating element 11 for rapid heating to boiling water. This greatly shortens the time required for the instant heating element 11 to heat the water to boiling and directly send it to the hot water outlet 18, effectively improving the water output response speed and water output of the integrated water purifier and heat pump. This not only shortens the waiting time for users to get hot water, but also helps to save energy.

[0040] Specifically, such as Figure 1As shown, the water circuit structure also includes an inlet valve 20, a booster pump 21, a wastewater valve 22, and a room temperature water outlet valve 23. The inlet valve 20 is used to control the water intake of the water circuit structure. The booster pump 21 pressurizes the incoming water before it enters the filter element 10. The wastewater valve 22 controls the filter element 10 to discharge wastewater. The room temperature water outlet valve 23 controls the filter element 10 to discharge room temperature water to the room temperature water outlet 24 of the whole machine. When the user selects room temperature water, the inlet valve 20 and the room temperature water outlet valve 23 are opened, and the booster pump 21 starts to work. The tap water passes through the inlet valve 20, the booster pump 21, and the filter element 10 in sequence and is filtered into pure water. The room temperature pure water then flows through the room temperature water outlet valve 23 and flows to the room temperature water outlet 24. Furthermore, since the amount of pure water filtered by the filter element 10 per unit time is much greater than the amount of water used for heating by the instantaneous heating element 11, the water circuit structure can also be equipped with a pressure reducing valve 25 and a first one-way valve 26. The pressure reducing valve 25 controls the amount of water discharged from the filter element 10 to the pure water circuit 13, and the excess water filtered out can be returned to the booster pump 21 through the first one-way valve 26. A flow meter 27 for monitoring the flow rate can be installed in the upstream water circuit of the instantaneous heating element 11. The inlet and outlet of the instantaneous heating element 11 are respectively connected to a first temperature sensor 28 and a second temperature sensor 29 to detect the inlet and outlet water temperatures, respectively. A third temperature sensor 30 for detecting the temperature of the liquid energy storage medium is installed in the energy storage tank 15. When the third temperature sensor 30 senses that the temperature of the liquid energy storage medium in the energy storage tank 15 is lower than the set temperature, the machine automatically controls the heating structure 16 to heat the liquid energy storage medium; when the third temperature sensor 30 senses that the temperature of the liquid energy storage medium has been heated to the set temperature, the heating structure 16 stops heating. The heating structure 16 can be an existing structure such as an electromagnetic heating plate or a heating wire.

[0041] As a preferred embodiment of this application, such as Figure 2 As shown, the cooling water path 12 is nested within the pure water path 13, and the pure water path 13 is nested within the medium water path 14, forming a nested heat exchange. The water flow in the pure water path 13 fully surrounds the outer wall of the cooling water path 12, and the liquid energy storage medium in the medium water path 14 fully surrounds the outer wall of the pure water path 13. This helps to improve the heat exchange efficiency of the heat exchange module, shorten the heat exchange time, and enable the integrated water purifier and heat pump to quickly meet the user's selected outlet water temperature requirements. Specifically, regarding the specific structure of the heat exchange module, for example, the heat exchange module can include three water pipes, which are nested layer by layer. The innermost water pipe forms the cooling water path 12, the middle water pipe and the innermost water pipe form the pure water path 13, and the middle water pipe and the outermost water pipe form the medium water path 14. Of course, the heat exchange module can also use other suitable structures to form the cooling water path 12, the pure water path 13, and the medium water path 14, which is not limited here. As an alternative, the cooling water path 12 and the medium water path 14 can be swapped, that is, the medium water path 14 is nested within the pure water path 13, and the pure water path 13 is nested within the cooling water path 12.

[0042] Furthermore, the inlet of the cooling water path 12 is close to the outlet of the pure water path 13, and the outlet of the cooling water path 12 is close to the inlet of the pure water path 13, so that the water flow direction in the cooling water path 12 is opposite to the water flow direction in the pure water path 13. This allows the hot water in the cooling water path 12 and the room temperature water in the pure water path 13 to flow in opposite directions and exchange heat when the hot water from the instantaneous heat exchanger 11 is delivered to the cooling water path 12. This maximizes the use of the temperature difference between the hot and cold water, so as to achieve the effect of higher temperature rise of room temperature water and lower temperature drop of boiling water.

[0043] As a preferred embodiment of this application, such as Figure 1 As shown, the energy storage tank 15 is provided with a medium outlet 151 for conveying liquid energy storage medium to the medium water channel 14 and a medium inlet 152 for the liquid energy storage medium to flow back from the medium water channel 14. The medium outlet 151 is positioned on the energy storage tank 15 higher than the medium inlet 152. Those skilled in the art will understand that for most liquid fluids, the density at high temperatures is usually lower than that at room or low temperatures. When the liquid energy storage medium used also meets this condition, the characteristics of the liquid energy storage medium, where the higher the density, the more concentrated it is at the bottom of the energy storage tank 15, and the lower the density, the more concentrated it is at the top of the energy storage tank 15, can be utilized. Thus, when the medium outlet 151 is positioned higher than the medium inlet 152 on the energy storage tank 15, it is convenient for the liquid energy storage medium supplied from the energy storage tank 15 to the medium water path 14 during the circulation of hot water between the energy storage tank 15 and the medium water path 14 to be as high-temperature liquid energy storage medium as possible. This allows the liquid energy storage medium to transfer more and faster heat to the room-temperature water in the pure water path 13 during heat exchange between the medium water path 14 and the pure water path 13, resulting in a higher temperature rise and a larger volume of water.

[0044] Regarding the specific source of the liquid energy storage medium, in a preferred embodiment, such as Figure 1 As shown, the energy storage tank 15 is provided with a medium supply port 153. The pure water outlet is connected to the medium supply port 153 through a water supply valve 31, so that the pure water filtered by the filter element 10 can be transported into the energy storage tank 15 to form a liquid energy storage medium. Those skilled in the art will understand that water has a large specific heat capacity and thermal conductivity. Using water as a liquid energy storage medium can store more heat and transfer heat from the medium water path 14 to the pure water path 13 more quickly, improving heat exchange efficiency. Specifically, the energy storage tank 15 can be provided with an exhaust port 154, which is connected to an exhaust pipe. The exhaust pipe is equipped with a second one-way valve 32.

[0045] Furthermore, such as Figure 1As shown, the energy storage tank 15 is equipped with a water level detection module 33 for detecting the water level of the liquid energy storage medium. The water level detection module 33 includes a high water level detection sensor and a low water level detection sensor. When the high water level detection sensor detects the target water level, the water supply valve 31 closes, causing the filter element 10 to stop supplying water to the energy storage tank 15. When the low water level detection sensor detects the target water level, the water supply valve 31 opens, allowing the filter element 10 to supply water to the energy storage tank 15. Specifically, the target water level detected by the high water level detection sensor can be set to a high water level, and the target water level detected by the low water level detection sensor can be set to a low water level. Thus, the water level detection module 33 controls the water level of the liquid energy storage medium in the energy storage tank 15 to be neither higher than the high water level nor lower than the low water level. When the integrated water purifier and heat pump is powered on for the first time, or when the low water level detection sensor installed in the energy storage tank 15 detects that the water level in the energy storage tank 15 is insufficient, the integrated water purifier and heat pump will automatically replenish the water in the energy storage tank 15. The inlet valve 20 and the replenishment valve 31 will open, and the booster pump 21 will start working. The tap water at room temperature will pass through the inlet valve 20, the booster pump 21, and the filter element 10 to be filtered into pure water. The pure water will then enter the energy storage tank 15 after passing through the replenishment valve 31. When the high water level detection sensor installed in the energy storage tank 15 detects that the water level in the energy storage tank 15 has reached the set high water level, the booster pump 21 will stop working, and the inlet valve 20 and the replenishment valve 31 will close, stopping the replenishment of water to the energy storage tank 15.

[0046] Regarding the specific source of the liquid energy storage medium, in another preferred embodiment, such as Figure 3 As shown, the energy storage tank 15 stores liquid energy storage medium through a sealable energy storage cavity. The energy storage tank 15 is equipped with a medium filling port 155 for injecting liquid energy storage medium into the energy storage cavity and a control valve 34 for opening or closing the medium filling port 155. The water circuit structure also includes a pressure relief channel for depressurizing the energy storage cavity, and a pressure relief valve 35 is provided on the fluid path of the pressure relief channel. In this scheme, the sealable condition of the energy storage cavity can be utilized to store energy using a liquid energy storage medium with a higher boiling point (such as heat transfer oil). The heating structure 16 is used to heat the energy storage temperature to a higher level (generally ≥100℃), so that the liquid energy storage medium stores more heat energy, resulting in a larger temperature difference between the liquid energy storage medium and the room temperature water to be heated in the pure water circuit 13, thereby obtaining higher heat exchange efficiency. This results in a higher water temperature after heat exchange in the pure water circuit 13 and a larger hot water outflow rate. When it is necessary to drain the liquid energy storage medium or when there are other needs, the pressure relief valve 35 can be opened in advance to depressurize the energy storage chamber.

[0047] As a preferred embodiment of this application, such as Figure 1As shown, the water circuit structure includes a mixing pipe 36 for discharging water to the hot water outlet 18. The cooling water circuit 12 and the instant heating element 11 are both connected to the hot water outlet 18 through the mixing pipe 36, so that the water discharged from the instant heating element 11 and the water discharged from the cooling water circuit 12 can be mixed in the mixing pipe 36 and then flow to the hot water outlet 18. By setting up a mixing pipe 36, the water discharged from the heating element 11 and the water discharged from the cooling water path 12 can be mixed in the mixing pipe 36 and then flow to the hot water outlet 18, which facilitates water temperature adjustment. For example, when the user selects the integrated water purifier and heat pump to discharge medium-high temperature cooled boiled water (50℃-90℃), the heating element 11 can simultaneously discharge boiling water into the mixing pipe 36 and the cooling water path 12. The boiling water in the cooling water path 12 exchanges heat with the room temperature water in the pure water path 13 to form low temperature cooled boiled water (generally ≤45℃), and then mixes with the boiling water directly delivered to the mixing pipe 36 by the heating element 11 in proportion, thereby obtaining high temperature cooled boiled water. When the user selects the integrated water purifier and heat pump to discharge low temperature cooled boiled water, the boiling water in the heating element 11 can be completely delivered to the cooling water path 12 and exchange heat with the pure water path 13, which can quickly form low temperature cooled boiled water. Specifically, a fourth temperature sensor 37 can be installed on the mixing pipe 36 to detect the outlet water temperature.

[0048] Since controlling the discharge of cooled boiled water at different temperatures by the integrated water purifier and heater requires adjusting the ratio of cooled boiled water and hot water discharged from the cooling water path 12 and the instant heating element 11 into the mixing pipe 36, in a preferred embodiment, as... Figure 1 As shown, the water circuit structure includes a proportional regulating valve 38. The outlet of the proportional regulating valve 38 is connected to the mixing pipe 36. The cooling water circuit 12 and the instant heating element 11 are respectively connected to the two inlets of the proportional regulating valve 38, so as to regulate the water flow rate to the mixing pipe 36 through the proportional regulating valve 38. The proportional regulating valve 38 is a valve that can adjust the opening size of the valve port. By adjusting the opening size of the two inlets, the mixing ratio of cooled boiled water and boiled water can be adjusted to achieve temperature regulation.

[0049] As an alternative embodiment, such as Figure 4 As shown, the instant heating element 11 is connected to the mixing pipe 36 via a hot water pump 39, and the cooling water path 12 is connected to the mixing pipe 36 via a warm water pump 40. Specifically, the outlet water temperature can be controlled by adjusting the water volume of the two paths, boiling water and cooled boiled water, by regulating the input voltage of the hot water pump 39 and the warm water pump 40.
