Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and in particular to an all-in-one water purifier and water heater. Background Art

[0002] Although the integrated water purifier and heat machine on the current market can provide purification and heating functions, they are insufficient in water temperature control and water resource utilization efficiency. Especially in winter or cold areas, when the integrated water purifier and heat machine is in standby for a long time and then started to use, the hot water flowing out of the hot water intake end of the faucet is often at a low temperature and needs to be discharged for a period of time before reaching the required use temperature, which leads to a waste of water resources and the water heat energy is not fully utilized. Summary of the invention

[0003] In view of this, the present invention provides an all-in-one water heater and heat pump to solve the problem in the prior art that when the all-in-one water heater and heat pump is started up after being on standby for a long time, the temperature of the hot water flowing out is low and it takes a while to reach the required operating temperature, which not only wastes water resources but also fails to fully utilize the water heat energy.

[0004] The present invention provides a water purification and heating integrated machine, comprising a water purification system, a heating module and a reflux module, the water purification system comprising a water production pipeline and a pre-filter and a fine filter element connected in series to the water production pipeline in sequence, the water purification system is used to produce pure water, the heating module is connected to the water outlet end of the water production pipeline, the heating module is used to heat the pure water flowing out of the water outlet end to a preset temperature value, the water outlet of the heating module is connected to the hot water intake end, the reflux module comprises a reflux branch and a control valve group, one end of the reflux branch is arranged between the heating module and the hot water intake end, the other end of the reflux branch is communicated with the water production pipeline between the pre-filter element and the fine filter element, the control valve group has a first state of conducting the reflux branch and the heating module, based on the outlet water temperature of the heating module being lower than the preset temperature value, the control valve group is in the first state to guide the hot water flowing out of the heating module that does not reach the preset temperature value into the water production pipeline between the pre-filter element and the fine filter element.

[0005] Beneficial effect: The integrated water purifier and heat machine of the present application is provided with a heating module and a reflux module. The heating module can heat the pure water prepared by the water purification system to a preset temperature value so that users can use hot water of the required temperature. When the integrated water purifier and heat machine is on standby for a long time in winter or cold areas and is started for use, the heating module cannot immediately heat the pure water to the preset temperature value. When the outlet water temperature of the heating module is lower than the preset temperature value, the control valve group of the reflux module is in the first state to conduct the reflux branch and the heating module, thereby guiding the hot water that does not reach the preset temperature value out of the heating module into the water production pipeline between the pre-filter element and the fine filter element to realize hot water reflux, thereby avoiding the waste of water resources and heat energy caused by direct discharge of hot water. At the same time, the refluxed hot water can increase the raw water temperature by mixing with the raw water in the water production pipeline, thereby increasing the raw water temperature entering the fine filter element for filtration, ensuring the filtering performance of the fine filter element, and alleviating the situation where the filtering performance of the fine filter element decreases due to too low temperature. In addition, the raw water heating also helps to improve the heating efficiency of the rear-end heating module.

[0006] In some embodiments, the control valve group also has a second state of conducting the heating module and the hot water intake end, and based on the outlet water temperature of the heating module being at the preset temperature value, the control valve group is in the second state.

[0007] Beneficial effect: When the outlet water temperature of the heating module is at the preset temperature value, the heating module and the hot water intake end are connected through the control valve group, so that the hot water taken by the user through the hot water intake end is maintained at the required preset temperature value. Therefore, the air purifier and heat integrated machine of the present application will turn on the reflux mode when the hot water does not meet the water intake demand and will not turn on the hot water intake end until the hot water is at the preset temperature value. This can ensure that the hot water flowing to the hot water intake end is always at the preset temperature value, so that the user can use it directly, reducing the waiting time for water intake.

[0008] In some embodiments, the heating module further includes a temperature detection unit, and the temperature detection unit is capable of controlling the control valve group to switch to the first state when it is detected that the outlet water temperature of the heating module is lower than the preset temperature value.

[0009] Beneficial effect: The temperature detection unit can detect the hot water temperature of the heating unit in time. When it is detected that the outlet water temperature of the heating unit is lower than the preset temperature value, the control valve group is controlled to switch to the first state to automatically turn on the hot water reflux mode, thereby improving control efficiency.

[0010] In some embodiments, the temperature detection unit can also control the control valve group to switch to the second state when it is detected that the outlet water temperature of the heating module is at the preset temperature value.

[0011] Beneficial effect: When the temperature detection unit detects that the water outlet temperature of the heating unit is at a preset temperature value, the control valve group is controlled to switch to the second state to automatically connect the heating unit and the hot water intake end, which can facilitate users to obtain hot water at the required temperature and improve control efficiency.

[0012] In some embodiments, the control valve group includes a reflux valve and a water intake valve, the reflux valve is arranged in the reflux branch, the water intake valve is arranged between the heating module and the hot water intake end and the water intake valve is located downstream of the reflux branch, in the first state, the reflux valve is in an open state and the water intake valve is in a closed state, in the second state, the reflux valve is in a closed state and the water intake valve is in an open state.

[0013] Beneficial effect: With the above arrangement, when the control valve group is in the first state, it indicates that the outlet water temperature of the heating module is lower than the preset temperature value. Therefore, the hot water flowing out of the heating module flows back to the water production pipeline through the reflux branch and mixes with the raw water. When the control valve group is in the second state, it indicates that the outlet water temperature of the heating module is at the preset temperature value. At this time, the water intake valve connects the heating module and the hot water intake end. When the user opens the water intake end, the hot water of the preset temperature value flowing out of the heating module can flow to the hot water intake end for the user to use.

[0014] In some embodiments, the reflux module further includes a check valve, which is disposed in the reflux branch and is located downstream of the reflux valve.

[0015] Beneficial effect: A check valve is further arranged in the reflux branch to prevent the hot water in the reflux branch from flowing back, and the check valve is located downstream of the reflux valve to protect the reflux valve and prevent the hot water from flowing back into the reflux valve and causing damage to the valve.

[0016] In some embodiments, the water purification system further includes a pressure-stabilizing pump, which is disposed on the water production pipeline between the pre-filter element and the fine filter element, and the connection point between the reflux branch and the water production pipeline is located upstream of the pressure-stabilizing pump.

[0017] Beneficial effect: The pressure-stabilizing pump can increase the pressure of raw water entering the fine filter element. Since the front end (upstream) of the pressure-stabilizing pump is zero pressure or negative pressure, it is more conducive to the return of hot water to the water production pipeline, reducing the difficulty of hot water return.

[0018] In some embodiments, the heating module includes a hot water pipeline and a heating unit arranged in the hot water pipeline, one end of the hot water pipeline is connected to the water outlet end of the water production pipeline, the other end of the hot water pipeline is connected to the hot water intake end, one end of the reflux branch is connected to the hot water pipeline, and the connection point between the reflux branch and the hot water pipeline is located between the heating unit and the hot water intake end.

[0019] Beneficial effect: Pure water flowing out of the water outlet of the water production pipeline flows into the heating unit through the hot water pipeline for heating. If the hot water is heated to the preset temperature value, it flows to the hot water intake end for users to use. If the hot water is not heated to the preset temperature value, it flows into the reflux branch through the hot water pipeline for reflux.

[0020] In some embodiments, the integrated heat and water purification machine further includes a flow regulating device, which is connected to the hot water pipeline and the connection is located upstream of the heating unit, and the flow regulating device is used to regulate the flow of pure water entering the heating unit.

[0021] Beneficial effect: A flow regulating device is provided to regulate the flow of pure water entering the heating unit, thereby adjusting the heating temperature of the pure water by the heating unit, realizing the use of hot water with multiple different preset temperature values, and meeting different water needs.

[0022] In some embodiments, the flow regulating device includes a controller and a water pump, the controller and the water pump are signal-connected, the water pump is arranged in the hot water pipeline, and the controller can control to reduce the pump pressure of the water pump when the outlet water temperature of the heating module is lower than the preset temperature value, and can control to increase the pump pressure of the water pump when the outlet water temperature of the heating module is higher than the preset temperature value.

[0023] Beneficial effect: When the preset temperature value of hot water needs to be adjusted, the temperature detection unit will first feedback the hot water temperature. When the existing hot water temperature is higher than the preset temperature value, the controller controls to increase the water pump pressure and thereby increase the flow of pure water into the heating unit, so that the hot water temperature drops. When the existing hot water temperature is lower than the preset temperature value, the controller controls to reduce the water pump pressure and thereby reduce the flow of pure water into the heating unit, and the hot water temperature rises, thereby realizing hot water extraction in multiple temperature ranges.

[0024] In some embodiments, the integrated heat and water purification machine also includes a pressure relief module, one end of the pressure relief module is connected to the water production pipeline upstream of the fine filter element, and the other end of the pressure relief module is connected to the water production pipeline downstream of the fine filter element. The pressure relief module is used to introduce part of the clean water prepared by the fine filter element into the water production pipeline upstream of the fine filter element when the heating module is running.

[0025] Beneficial effect: The setting of the pressure relief module can guide part of the clean water prepared by the fine filter element into the water production pipeline upstream of the fine filter element when the heating module is running, so that part of the clean water prepared by the fine filter element can flow back to the front end to reduce the pressure at the rear end of the fine filter element, thereby preventing the water pressure of the water purification system from being too high when taking hot water, causing damage to the pipeline.

[0026] In some embodiments, the water purification system further comprises a post-filter element, wherein the post-filter element is serially connected to the water production pipeline downstream of the fine filter element;

[0027] The pressure relief module includes a pressure relief branch and a pressure relief valve arranged on the pressure relief branch, one end of the pressure relief branch is connected to the water production pipeline between the pre-filter element and the fine filter element, and the other end of the pressure relief branch is connected to the water production pipeline between the post-filter element and the fine filter element, and the pressure relief valve is used to open when the heating module is running to conduct the pressure relief branch.

Part of the clean water prepared by the fine filter element flows into the pressure relief branch under back pressure and flows into the water production pipeline between the pre-filter element and the fine filter element, mixes with the raw water, and then flows into the fine filter element again for circulation filtration.

[0029] In some embodiments, the air conditioner and heat integrated machine also includes a normal temperature water intake module, which includes a normal temperature water pipeline and a normal temperature water inlet valve.

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0048] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0049] According to an embodiment of the present invention, Figures 1 to 3 As shown, a water purification and heating integrated machine is provided, including a water purification system 1, a heating module 2 and a reflux module 3. The water purification system 1 includes a water production pipeline 11 and a pre-filter element 12 and a fine filter element 13 connected in series to the water production pipeline 11 in sequence. The water purification system 1 is used to produce pure water. The heating module 2 is connected to the water outlet end of the water production pipeline 11. The heating module 2 is used to heat the pure water flowing out of the water outlet end to a preset temperature value. The water outlet of the heating module 2 is connected to the hot water intake end 611. The reflux module 3 includes a reflux branch 31 and a control valve group One end of the reflux branch 31 is arranged between the heating module 2 and the hot water intake end 611, and the other end of the reflux branch 31 is connected to the water production pipeline 11 between the pre-filter element 12 and the fine filter element 13. The control valve group has a first state of connecting the reflux branch 31 and the heating module 2. Based on the outlet water temperature of the heating module 2 being lower than the preset temperature value, the control valve group is in the first state to guide the hot water that does not reach the preset temperature value flowing out of the heating module 2 into the water production pipeline 11 between the pre-filter element 12 and the fine filter element 13.

[0050] The integrated water purifier and heat machine of the present application is provided with a heating module 2 and a reflux module 3. The heating module 2 can heat the pure water prepared by the water purification system 1 to a preset temperature value so that the user can use the hot water of the required temperature. When the integrated water purifier and heat machine is in standby for a long time in winter or cold areas and is started for use, the heating module 2 cannot immediately heat the pure water to the preset temperature value. When the outlet water temperature of the heating module 2 is lower than the preset temperature value, the control valve group of the reflux module 3 is in the first state to conduct the reflux branch 31 and the heating module 2, so that the flow of the heating module 2 is The hot water that does not reach the preset temperature value is introduced into the water production pipeline 11 between the pre-filter element 12 and the fine filter element 13 to realize the reflux of hot water, which not only avoids the waste of water resources and heat energy caused by the direct discharge of hot water, but also the refluxed hot water can increase the temperature of the raw water by mixing with the raw water in the water production pipeline 11, thereby increasing the temperature of the raw water entering the fine filter element 13 for filtration, ensuring the filtering performance of the fine filter element 13, and alleviating the situation where the filtering performance of the fine filter element 13 decreases due to too low temperature. In addition, the heating of the raw water also helps to improve the heating efficiency of the rear-end heating module 2.

[0051] It should be noted that the preset temperature value can be adjusted according to user needs. For example, if a user wants to make tea, the preset temperature value may be 100°C, and if a user wants to make milk, the preset temperature value may be 45°C to 55°C. This embodiment does not impose any specific limitation.

[0052] The fine filter element 13 is generally any one or more of a reverse osmosis membrane filter element (RO filter element) or a nanofiltration membrane filter element or a ceramic membrane filter element, etc., which has a certain osmotic pressure. According to the principle of thermal expansion and contraction, too low a temperature will cause the osmotic pressure of the fine filter element 13 to be too high, resulting in increased difficulty in filtering water through the fine filter element 13. Therefore, in winter or cold areas, the filtering performance of the fine filter element 13 will decrease due to the low temperature. The present application can increase the temperature of the raw water entering the fine filter element 13 by introducing hot water that has not reached the preset temperature value into the front end of the fine filter element 13 and mixing it with raw water, thereby heating the fine filter element 13 through the raw water, thereby improving the activity of the fine filter element 13, ensuring the filtering performance, and realizing the recovery and utilization of heat energy.

[0053] In some embodiments, the control valve group also has a second state of connecting the heating module 2 and the hot water intake end 611. Based on the outlet water temperature of the heating module 2 being at a preset temperature value, the control valve group is in the second state.

[0054] When the outlet water temperature of the heating module 2 is at the preset temperature value, the heating module 2 and the hot water intake terminal 611 are connected by controlling the valve group so that the hot water taken by the user through the hot water intake terminal 611 is maintained at the required preset temperature value. Therefore, the air purifier and heat integrated machine of the present application will turn on the reflux mode when the hot water does not meet the water intake demand and will not turn on the hot water intake terminal 611 until the hot water is at the preset temperature value. This can ensure that the hot water flowing to the hot water intake terminal 611 is always at the preset temperature value, so that the user can directly take it, thereby reducing the waiting time for water intake.

[0055] In some embodiments, the control valve group includes a reflux valve 32 and a water intake valve 24, wherein the reflux valve 32 is arranged in the reflux branch 31, and the water intake valve 24 is arranged between the heating module 2 and the hot water intake end 611 and the water intake valve 24 is located downstream of the reflux branch 31. In a first state, the reflux valve 32 is in an open state and the water intake valve 24 is in a closed state. In a second state, the reflux valve 32 is in a closed state and the water intake valve 24 is in an open state.

[0056] In the above arrangement, when the control valve group is in the first state, it means that the outlet water temperature of the heating module 2 is lower than the preset temperature value, so the hot water flowing out of the heating module 2 flows back to the water production pipeline 11 through the reflux branch 31 and mixes with the raw water. When the control valve group is in the second state, it means that the outlet water temperature of the heating module 2 is at the preset temperature value. At this time, the water intake valve 24 connects the heating module 2 and the hot water intake end 611. When the user opens the water intake end, the hot water with the preset temperature value flowing out of the heating module 2 can flow to the hot water intake end 611 for the user to use.

[0057] Specifically, the reflux valve 32 and the water intake valve 24 can be set as solenoid valves, and the on and off can be conveniently controlled by controlling the power supply of the solenoid valves, but it is not limited to this. For example, the reflux valve 32 and the water intake valve 24 can also be set as stop valves and other valves that can control the on and off of the pipeline.

[0058] In other embodiments, the control valve group includes a pipeline switching valve, which includes an inlet, a first outlet and a second outlet. The inlet is connected to the water outlet of the heating module 2, the first outlet is connected to the reflux branch 31, and the second outlet is connected to the hot water intake end 611. When the control valve group is in a first state, the inlet is connected to the first outlet. At this time, the hot water in the heating module 2 that has not reached the preset temperature value flows through the inlet and the first outlet through the reflux branch 31 and then flows back to the water production pipeline 11. When the control valve group is in a second state, the inlet and the second outlet are connected. At this time, the hot water with the preset temperature value in the heating module 2 flows through the inlet and the second outlet to the hot water intake end 611.

[0059] The pipeline switching valve is specifically a three-way valve.

[0060] In some embodiments, the reflux module 3 further includes a check valve 33 , which is disposed in the reflux branch 31 and is located downstream of the reflux valve 32 .

[0061] A check valve 33 is further provided in the reflux branch 31 to prevent the hot water in the reflux branch 31 from flowing back, and the check valve 33 is located downstream of the reflux valve 32 to protect the reflux valve 32 and prevent the hot water from flowing back into the reflux valve 32 and causing valve damage.

[0062] Preferably, the check valve 33 is disposed close to the reflux valve 32 , so as to prevent the hot water in the reflux branch 31 from flowing back to the reflux valve 32 in time.

[0063] In some embodiments, the water purification system 1 also includes a pressure-stabilizing pump 19, which is arranged on the water production pipeline 11 between the pre-filter element 12 and the fine filter element 13, and the connection point between the reflux branch 31 and the water production pipeline 11 is located upstream of the pressure-stabilizing pump 19.

[0064] The pressure-stabilizing pump 19 can increase the pressure of the raw water entering the fine filter element 13. Since the front end (upstream) of the pressure-stabilizing pump 19 is at zero pressure or negative pressure, it is more conducive to the reflux of hot water into the water production pipeline 11, reducing the difficulty of hot water reflux.

[0065] In some embodiments, the heating module 2 includes a hot water pipeline 21 and a heating unit 22 arranged on the hot water pipeline 21, one end of the hot water pipeline 21 is connected to the water outlet end of the water production pipeline 11, the other end of the hot water pipeline 21 is connected to the hot water intake end 611, one end of the reflux branch 31 is connected to the hot water pipeline 21, and the connection point between the reflux branch 31 and the hot water pipeline 21 is located between the heating unit 22 and the hot water intake end 611.

[0066] The pure water flowing out of the water outlet end of the water production pipeline 11 flows into the heating unit 22 through the hot water pipeline 21 for heating. If the hot water is heated to a preset temperature value, it flows to the hot water intake end 611 for user use. If the hot water is not heated to the preset temperature value, it flows into the reflux branch 31 through the hot water pipeline 21 for reflux.

[0067] In this embodiment, the water intake valve 24 is arranged in the hot water pipeline 21 and is located between the reflux branch 31 and the hot water intake end 611 . Closing of the water intake valve 24 does not affect the conduction between the reflux branch 31 and the heating unit 22 .

[0068] Preferably, the heating unit 22 is configured as a rare earth thick film heating body, which can achieve instant and rapid heating of water and more uniform heating, but is not limited thereto. For example, in other embodiments, the heating unit 22 can also be a structure such as an electric heating wire or a heating rod.

[0069] In some embodiments, the heating module 2 further includes a temperature detection unit 23. The temperature detection unit 23 can control the control valve group to switch to the first state when it detects that the outlet water temperature of the heating unit 22 is lower than a preset temperature value.

[0070] The temperature detection unit 23 can timely detect the hot water temperature of the heating unit 22. When it is detected that the outlet water temperature of the heating unit 22 is lower than the preset temperature value, the control valve group is controlled to switch to the first state to automatically turn on the hot water reflux mode to improve the control efficiency.

[0071] In some embodiments, the temperature detection unit 23 can also control the control valve group to switch to the second state when it is detected that the outlet water temperature of the heating module 2 is at a preset temperature value.

[0072] When the temperature detection unit 23 detects that the water outlet temperature of the heating unit 22 is at a preset temperature value, the control valve group is controlled to switch to the second state to automatically connect the heating unit 22 and the hot water intake end 611, which can facilitate users to obtain hot water of the required temperature and improve control efficiency.

[0073] Specifically, the controller controls the switching of the control valve group, the temperature detection unit 23 feeds back the information that the outlet water temperature of the heating unit 22 is lower than the preset temperature value to the controller, and the controller controls the control valve group to switch to the first state based on the feedback information, the temperature detection unit 23 feeds back the information that the outlet water temperature of the heating unit 22 is at the preset temperature value to the controller, and the controller controls the control valve group to switch to the second state based on the feedback information.

[0074] In some embodiments, the temperature detection unit 23 can be set as a temperature sensing bag, which is set in the heating unit 22 to detect the water outlet temperature of the heating unit 22 in real time, but it is not limited to this. For example, in other embodiments, the temperature detection unit 23 can also be set as a temperature sensor, or the temperature detection unit 23 can also be set in the hot water pipeline 21.

[0075] In some embodiments, the air conditioner and heat unit also includes a flow regulating device, which is connected to the hot water pipeline 21 and the connection is located upstream of the heating unit 22. The flow regulating device is used to regulate the flow of pure water entering the heating unit 22.

[0076] A flow regulating device is provided to regulate the flow of pure water entering the heating unit 22, thereby adjusting the heating temperature of the pure water by the heating unit 22, and realizing the use of hot water with multiple different preset temperature values ​​to meet different water needs.

[0077] Specifically, when the preset temperature value of the hot water needs to be adjusted, the temperature detection unit 23 first feeds back the hot water temperature. When the existing hot water temperature is higher than the preset temperature value, the flow regulating device increases the flow of pure water entering the heating unit 22, so that the hot water temperature drops. When the existing hot water temperature is lower than the preset temperature value, the flow regulating device reduces the flow of pure water entering the heating unit 22, so that the hot water temperature rises, thereby realizing the use of hot water in multiple temperature ranges.

[0078] In some embodiments, the flow regulating device includes a controller and a water pump 213, the controller and the water pump 213 are signal-connected, the water pump 213 is arranged in the hot water pipeline 21, and the controller can control to reduce the pump pressure of the water pump 213 when the outlet water temperature of the heating module 2 is lower than the preset temperature value, and can control to increase the pump pressure of the water pump 213 when the outlet water temperature of the heating module 2 is higher than the preset temperature value.

[0079] When the preset temperature value of the hot water needs to be adjusted, the temperature detection unit 23 first feeds back the hot water temperature. When the existing hot water temperature is higher than the preset temperature value, the controller controls to increase the pump pressure of the water pump 213 and thereby increase the flow rate of pure water flowing into the heating unit 22, so that the hot water temperature drops. When the existing hot water temperature is lower than the preset temperature value, the controller controls to reduce the pump pressure of the water pump 213 and thereby reduce the flow rate of pure water flowing into the heating unit 22, and the hot water temperature rises, thereby realizing the use of hot water in multiple temperature ranges.

[0083] When the heating module 2 is running, the pressure relief valve 42 opens and the pressure relief branch 41 is conducted. Part of the clean water prepared by the fine filter element 13 flows into the pressure relief branch 41 under back pressure and flows into the water production pipeline 11 between the pre-filter element 12 and the fine filter element 13, mixes with the raw water, and then flows into the fine filter element 13 again for circulation filtration.

[0097] The zero pressure valve 212 is disposed in the hot water pipeline 21 and is located downstream of the water pump 213 .

[0098] In addition to the above-mentioned configuration, in some embodiments, the integrated heat and water purification machine further includes a pipeline machine branch 7, which is connected to the water outlet end of the water production pipeline 11. The pipeline machine branch 7 is used to connect the pipeline machine to facilitate the introduction of pure water flowing out of the water production pipeline 11 into the pipeline machine for user use.

[0099] To facilitate understanding of the integrated heat and air purifier of this embodiment, the following is an introduction to its use process:

[0100] When the heating module 2 or the normal temperature water intake module 5 is in operation, the water purification system 1 operates to produce water, so as to purify the raw water into pure water, which then flows to the heating module 2 or the normal temperature water intake module 5 for users to take;

[0101] When the water purification system 1 is in operation, raw water flows in from the raw water inlet, first passes through the pre-filter element 12 for pre-treatment, filters out impurities such as silt, rust, and solid pollutants in the water, and then flows into the fine filter element 13 through the water production pipeline 11 for filtration treatment, filtering out bacteria, viruses and other fine pollutants in the water. After the filtration treatment, the purified water flows out from the pure water port 132 and is further filtered through the post-filter element 14 to absorb residual odors and discoloration in the water, improve the taste, and obtain pure water, which is finally discharged from the water outlet of the water production pipeline 11 into the heating module 2 or the normal temperature water intake module 5;

[0102] When the user needs to take hot water, the heating module 2 is operated, the third water inlet valve 211 is opened, and the normal temperature water inlet valve 52 is closed, pure water flows from the water production pipeline 11 into the hot water pipeline 21, and flows through the third water inlet valve 211, the water pump 213, and the zero-pressure valve 212 in sequence to flow into the heating unit 22 for heating, and the temperature detection unit 23 detects the hot water temperature in real time. When the hot water temperature is lower than the preset temperature value, the reflux valve 32 is opened and the water intake valve 24 is closed. The hot water that does not reach the preset temperature value flows into the water production pipeline 11 at the front end of the pressure-stabilizing pump 19 through the reflux branch 31, mixes with the raw water, and then flows into the fine filter element 13 for filtration again. After filtration, the pure water enters the heating unit 22 for further heating. When the hot water temperature is at the preset temperature value, the reflux valve 32 is closed and the water intake valve 24 is opened. The hot water of the preset temperature value flows into the hot water intake end 611 through the hot water pipeline 21 for the user to take;

[0103] During the operation of the heating module 2, the pressure relief module 4 is in operation, that is, the pressure relief valve 42 and the pressure relief solenoid valve 43 are both open, and a portion of the clean water filtered out by the fine filter element 13 flows back to the water production pipeline 11 at the front end of the pressure regulating pump 19 through the pressure relief branch 41, mixes with the raw water, and then flows into the fine filter element 13 for further filtration, thereby avoiding excessive pressure at the outlet end of the water production pipeline 11 causing damage to the pipeline;

[0104] When the preset temperature value needs to be adjusted, the temperature of the hot water is detected by the temperature detection unit 23. If the temperature of the hot water is higher than the preset temperature value, the controller controls to increase the pump pressure of the water pump 213 and thereby increase the flow rate of pure water flowing into the heating unit 22, so that the temperature of the hot water decreases. When the temperature of the hot water is lower than the preset temperature value, the controller controls to reduce the pump pressure of the water pump 213 and thereby reduce the flow rate of pure water flowing into the heating unit 22, so that the temperature of the hot water increases, thereby realizing the use of hot water in multiple temperature ranges.

[0105] When the user needs to take normal temperature water, the normal temperature water intake module 5 is in operation, the normal temperature water inlet valve 52 is opened and the third inlet valve 211 is closed, and the pure water flowing out of the outlet end of the water production pipeline 11 flows through the normal temperature water pipeline 51 to the normal temperature water intake end 612 for user use.

[0106] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present application.
