Description

Technical Field

[0001] This utility model relates to the field of water purification technology, specifically to an integrated water purification and heating machine. Background Technology

[0002] While current integrated water purifiers and heaters on the market offer both purification and heating functions, they fall short in terms of water temperature control and water resource utilization efficiency. Especially in winter or cold regions, when the integrated water purifier and heater has been idle for an extended period before being used, the hot water coming out of the faucet is often at a low temperature, requiring some time to run before reaching the desired operating temperature. This not only wastes water resources but also increases the waiting time for users to obtain hot water. Utility Model Content

[0003] In view of this, the present invention provides an integrated water purifier and heat pump to solve the problem that in the prior art, when an integrated water purifier and heat pump is in standby mode for a long time and then started, the hot water temperature is low and it takes a period of time to reach the required operating temperature, which not only wastes water resources but also increases the waiting time for users to get water.

[0004] The first aspect of this utility model provides an integrated water purification and heating machine, including a water purification system, a heating module, a reflux module, and a first sterilization module. The water purification system is used to produce pure water. The heating module is connected to the outlet of the water purification system and is used to heat the pure water flowing out of the outlet to a set value. The outlet of the heating module is connected to a hot water intake end. The reflux module is used to guide the hot water flowing out of the outlet of the heating module that has not reached the set value into the heating module or upstream of the heating module. The first sterilization module is disposed between the heating module and the hot water intake end.

[0005] Beneficial effects: The integrated water purifier and heater of this application can heat the pure water produced by the water purification system to a set value through the heating module, so that users can use hot water at the required temperature. When the integrated water purifier and heater is used after a long standby time in winter or cold regions, the heating module cannot immediately heat the pure water to the set value. When the water temperature of the heating module is lower than the set value, the return module can guide the hot water that has not reached the set value out of the heating module into the heating module or upstream of the heating module to realize the return of hot water and avoid the waste of water resources and heat energy caused by the direct discharge of hot water that has not reached the set value. The sterilization module can disinfect and sterilize the hot water out of the heating module to eliminate bacteria that grow when the whole machine has not been used for a long time.

[0006] In some embodiments, the reflux module includes: a reflux pipeline, one end of which is connected between the heating module and the hot water inlet, and the other end of which is connected upstream of the heating module; and a control valve group having a first state in which the outlet of the heating module and the reflux pipeline are connected, wherein the control valve group is in the first state based on the fact that the outlet water temperature of the heating module is lower than the set value.

[0007] Beneficial effect: When the outlet water temperature of the heating module is lower than the set value, the control valve group is in the first state to connect the outlet of the heating module and the return pipe, so that the hot water flowing out of the heating module that has not reached the set value is introduced into the upstream of the heating module through the return pipe, realizing hot water return.

[0008] In some embodiments, the control valve assembly also has a second state in which the outlet of the heating module and the hot water intake end are connected, and the control valve assembly is in the second state based on the fact that the outlet water temperature of the heating module is equal to the set value.

[0009] Beneficial effects: When the outlet water temperature of the heating module is equal to the set value, the control valve group is in the second state to conduct the heating module and the hot water outlet, so that the hot water taken by the user through the hot water outlet is kept at the required set value. Therefore, the water purifier and heat pump of this application will open the backflow mode when the hot water does not meet the water demand until the hot water is equal to the set value before conducting the hot water outlet. This can ensure that the hot water flowing to the hot water outlet is always at the set value, so that the user can take it directly and reduce the waiting time for water.

[0010] In some embodiments, the integrated water purifier and heater further includes a temperature sensor for detecting the outlet water temperature of the heating module; based on the temperature sensor detecting that the outlet water temperature of the heating module is lower than the set value, the control valve group is controlled to switch to the first state.

[0011] Beneficial effects: The temperature sensor can detect the hot water temperature of the heating module in a timely manner. When the outlet water temperature of the heating module is detected to be lower than the set value, the control valve group is switched to the first state to automatically start the hot water recirculation mode, thereby improving control efficiency.

[0012] In some embodiments, based on the temperature sensor detecting that the outlet water temperature of the heating module is equal to the set value, the control valve group is controlled to switch to the second state.

[0013] Beneficial effects: When the temperature sensor detects that the outlet water temperature of the heating module is equal to the set value, the control valve group switches to the second state to automatically connect the heating module and the hot water outlet, which makes it convenient for users to obtain hot water at the required temperature and improves control efficiency.

[0014] In some embodiments, the control valve assembly includes: a valve inlet connected to the outlet of the heating module; a first valve outlet connected to the return pipeline; and a second valve outlet connected to the hot water intake end. When the control valve assembly is in the first state, the valve inlet is connected to the first valve outlet, and when the control valve assembly is in the second state, the valve inlet is connected to the second valve outlet.

[0015] Beneficial effects: When the outlet water temperature of the heating module is detected to be lower than the set value, the control valve group switches to the first state to connect the valve inlet and the first valve outlet. The hot water flowing out of the heating module that has not reached the set value flows through the valve inlet, the first valve outlet and the return pipe and is then introduced upstream of the heating module to realize hot water return for reheating. When the outlet water temperature of the heating module is detected to be equal to the set value, the control valve group switches to the second state to connect the valve inlet and the second valve outlet. The hot water flowing out of the heating module that has reached the set value flows through the valve inlet and the second valve outlet and then flows to the hot water intake end for the user to use.

[0016] In some embodiments, the control valve assembly is a stepless regulating valve, which can control the opening degree of the outlet of the second valve to regulate the water flow rate.

[0017] Beneficial effects: By setting the control valve assembly as a stepless regulating valve, the regulation accuracy can be ensured, and the opening degree of the second valve outlet can be adjusted, thereby regulating the outflow rate.

[0018] In some embodiments, the first sterilization module is located downstream of the control valve assembly.

[0019] Beneficial effects: Due to the setting of the control valve group, it is inevitable that the water source will be polluted to a certain extent. Therefore, by setting the first sterilization module downstream of the control valve group, the hot water flowing out of the control valve group can be disinfected and sterilized to ensure drinking water health.

[0020] In some embodiments, the integrated water purifier and heater further includes a room temperature water outlet module, which is connected to the water outlet of the water purification system and to the room temperature water intake.

[0021] Beneficial effects: By setting up a room temperature water outlet module, when users need to take room temperature water, the pure water flowing out of the water purification system flows to the room temperature water intake end through the room temperature water outlet module, and users can take room temperature water from the room temperature water intake end, meeting different water needs.

[0022] In some embodiments, the integrated water purifier and heater further includes a second sterilization module, which is disposed on the ambient temperature water outlet module and is located near the ambient temperature water intake end.

[0023] Beneficial effects: The second sterilization module can disinfect and sterilize the room temperature water flowing out of the warm water outlet module to improve water safety. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0041] According to embodiments of the present invention, such as Figure 1 As shown, a water purification and heating integrated machine is disclosed, including a water purification system 1, a heating module 2, a reflux module 3, and a first sterilization module 5. The water purification system 1 is used to produce pure water. The heating module 2 is connected to the water outlet of the water purification system 1 and is used to heat the pure water flowing out of the water outlet to a set value. The water outlet of the heating module 2 is connected to a hot water intake 41. The reflux module 3 is used to guide the hot water flowing out of the water outlet of the heating module 2 that has not reached the set value into the heating module 2 or upstream of the heating module 2. The first sterilization module 5 is disposed between the heating module 2 and the hot water intake 41.

[0042] In this embodiment, the integrated water purifier and heater can heat the pure water produced by the water purification system 1 to a set value through the heating module 2, so that the user can use hot water at the required temperature. When the integrated water purifier and heater is used after a long standby time in winter or cold regions, the heating module 2 cannot immediately heat the pure water to the set value. When the outlet water temperature of the heating module 2 is lower than the set value, the return module 3 can guide the hot water that has not reached the set value out of the heating module 2 into the heating module 2 or upstream of the heating module 2 to realize the return of hot water and avoid the waste of water resources and heat energy caused by the direct discharge of hot water that has not reached the set value. The sterilization module can disinfect and sterilize the hot water out of the heating module 2 to eliminate bacteria that grow when the whole machine has not been used for a long time.

[0043] It should be noted that the set value can be adjusted according to the user's needs. For example, the user needs to set the value to 100℃ when brewing tea, and the user needs to set the value to 45℃ to 55℃ when brewing milk. This embodiment does not impose specific limitations.

[0044] like Figure 1 and Figure 2 As shown, the water purification system 1 includes a water production pipeline 11 and a pre-filter 12, a fine filter 13 and a post-filter 14 connected in series to the water production pipeline 11. The pre-filter 12 performs primary filtration of tap water, the fine filter 13 performs high-precision filtration of the primary filtered tap water to form pure water, and the post-filter 14 filters the pure water again to adjust the drinking taste and pH value of the pure water.

[0045] Water production pipeline 11 is connected to the raw water inlet, which is usually tap water, in order to purify the tap water.

[0046] The pre-filter 12 can be a filter made of PP cotton, activated carbon, and ultrafiltration. It can adsorb impurities such as sediment in the raw water and remove residual chlorine, thus achieving coarse filtration of the raw water.

[0047] The fine filter element 13 has a higher filtration accuracy than the pre-filter element 12, and it is the core treatment filter element of the water purification system 1. The fine filter element 13 is generally one or more of a reverse osmosis membrane filter element (RO filter element), a nanofiltration membrane filter element, or a ceramic membrane filter element, depending on the filtration requirements. This embodiment does not make specific limitations.

[0048] like Figures 2 to 4 As shown, the post-filter 14 can be a filter element made of PP cotton, activated carbon, and ultrafiltration, which can filter pure water again and remove residual chlorine from the water.

[0049] Specifically, the pre-filter 12 has a first inlet 121 and a first outlet 122. The first inlet 121 is connected to the inlet end of the water supply pipe 11, and the first outlet 122 is connected to the fine filter 13.

[0050] The fine filter element 13 has a fine filter element inlet 131, a pure water outlet 132 and a wastewater outlet 133. The fine filter element inlet 131 is connected to the first outlet 122, the pure water outlet 132 is connected to the post filter element 14, and the wastewater outlet 133 is connected to the wastewater pipeline 10.

[0051] The post-filter 14 has a second inlet 141 and a second outlet 142, wherein the second inlet 141 is connected to the pure water outlet 132, and the second outlet 142 is connected to the outlet end of the water production pipeline 11.

[0052] It is understandable that the first water outlet 122 and the fine filter element inlet 131, as well as the fine filter element inlet 131 and the second water inlet 141, are all connected by the water production pipeline 11.

[0053] In some embodiments, a wastewater valve 101 is provided on the wastewater pipeline 10, and the wastewater valve 101 is used to control the opening and closing of the wastewater pipeline 10.

[0054] The pre-filter 12 and post-filter 14 can be integrated into a composite filter or set up separately.

[0055] In addition to the above-described configuration, in some embodiments, the water purification system 1 further includes the following structures:

[0056] Pressure reducing valve 15: Pressure reducing valve 15 is installed on the water production pipeline 11 upstream of the pre-filter 12 and is used to control the opening and closing of the water inlet end of the water production pipeline 11.

[0057] First TDS probe 16: The first TDS probe 16 is installed in the water purification pipeline 11 between the pre-filter 12 and the fine filter 13. The first TDS probe 16 is used to detect the raw water quality so as to facilitate timely understanding of the raw water quality.

[0058] First solenoid valve 17: The first solenoid valve 17 is located in the water production pipeline 11 between the pre-filter 12 and the fine filter 13, and the first solenoid valve 17 is located downstream of the first TDS probe 16. The first solenoid valve 17 is used to control the opening and closing of the water production pipeline 11 in this section, thereby controlling the flow of raw water into the fine filter 13.

[0059] First flow meter 18: The first flow meter 18 is installed in the water production pipeline 11 between the pre-filter 12 and the fine filter 13, and the first flow meter 18 is located downstream of the first solenoid valve 17. The first flow meter 18 is used to detect the raw water flow rate so as to understand the total water purification volume of the whole machine.

[0060] Pressure stabilizing pump 19: The pressure stabilizing pump 19 is installed in the water production pipeline 11 between the pre-filter 12 and the fine filter 13. The pressure stabilizing pump 19 is located downstream of the first flow meter 18. The pressure stabilizing pump 19 is used to pressurize the raw water so that it passes through the fine filter 13, thereby improving the filtration efficiency.

[0061] Check valve 111: Check valve 111 is installed in the water supply line 11 downstream of the post-filter cartridge 14. Check valve 111 is used to prevent pure water from flowing back into the post-filter cartridge 14.

[0062] Second TDS probe 112: The second TDS probe 112 is located in the water purification pipeline 11 downstream of the post-filter cartridge 14, and the second TDS probe 112 is located downstream of the check valve 111. The second TDS probe 112 is used to detect the pure water quality, so as to facilitate timely understanding of the drinking water quality, prevent water quality from exceeding the standard, and ensure drinking water health.

[0063] Temperature sensor 113: The temperature sensor 113 is located in the water purification pipeline 11 downstream of the post-filter cartridge 14, and the temperature sensor 113 is located downstream of the second TDS probe 112. The temperature sensor 113 is used to detect the pure water temperature so as to facilitate timely understanding of the drinking water temperature.

[0064] Second flow meter 114: The second flow meter 114 is installed in the water production pipeline 11 downstream of the post-filter cartridge 14, and the second flow meter 114 is located downstream of the temperature sensing bulb 113. The second flow meter 114 is used to detect the pure water flow rate, so as to facilitate timely detection of water intake and realize quantitative water intake. It can also facilitate understanding of the total water production of the water purification system 1, which helps to determine the service life of the water purification system 1.

[0065] It should be noted that both the first TDS probe 16 and the second TDS probe 112 are used to detect the TDS content in the water to obtain the TDS value. The water quality can be determined by the range of the TDS value.

[0066] For example, the TDS value of purified water is usually below 50, which is considered a safe drinking standard. When the TDS value of purified water detected by the second TDS probe 112 is greater than 50, an alarm will be issued to remind the user to avoid drinking water with excessive quality.

[0067] like Figure 2 As shown, in some embodiments, the integrated water purifier and heater also includes a pressure relief module 20. One end of the pressure relief module 20 is connected to the water production pipeline 11 upstream of the fine filter element 13, and the other end of the pressure relief module 20 is connected to the water production pipeline 11 downstream of the fine filter element 13. The pressure relief module 20 is used to introduce part of the pure water prepared by the fine filter element 13 into the water production pipeline 11 upstream of the fine filter element 13 when the heating module 2 is running.

[0068] The pressure relief module 20 can guide part of the pure water produced by the fine filter element 13 into the water production pipeline 11 upstream of the fine filter element 13 when the heating module 2 is running, thereby realizing the return of part of the pure water produced by the fine filter element 13 to the front end, so as to reduce the pressure at the rear end of the fine filter element 13 and prevent the pipeline from being damaged due to excessive water pressure in the pure water system when hot water is taken.

[0069] In some embodiments, the pressure relief module 20 includes a pressure relief branch 201 and a pressure relief valve 202 disposed on the pressure relief branch 201. One end of the pressure relief branch 201 is connected to the water supply pipeline 11 between the pre-filter 12 and the fine filter 13, and the other end of the pressure relief branch 201 is connected to the water supply pipeline 11 between the post-filter 14 and the fine filter 13. The pressure relief valve 202 is used to open to conduct the pressure relief branch 201 when the heating module 2 is running.

[0070] When the heating module 2 is running, the pressure relief valve 202 opens and the pressure relief branch 201 is opened. Some of the pure water produced by the fine filter element 13 flows into the pressure relief branch 201 under back pressure and flows into the water production pipeline 11 between the pre-filter element 12 and the fine filter element 13. After mixing with the raw water, it flows back into the fine filter element 13 for circulation filtration.

[0071] Preferably, the connection point of the pressure relief branch 201 with the water production pipeline 11 between the pre-filter 12 and the fine filter 13 is located upstream of the pressure stabilizing pump 19, so as to facilitate pure water reflux under the action of zero pressure or negative pressure at the front end of the pressure stabilizing pump 19.

[0072] The pressure relief module 20 also includes a pressure relief solenoid valve 203, which is installed in the pressure relief pipeline and is used to automatically control the opening and closing of the pressure relief pipeline.

[0073] like Figure 1 and Figure 5 As shown, in some embodiments, the return module 3 includes a return pipe 31 and a control valve group 32. One end of the return pipe 31 is connected between the heating module 2 and the hot water inlet 41, and the other end of the return pipe 31 is connected upstream of the heating module 2. The control valve group 32 has a first state in which the outlet of the heating module 2 and the return pipe 31 are connected. Based on the fact that the outlet water temperature of the heating module 2 is lower than the set value, the control valve group 32 is in the first state.

[0074] When the outlet water temperature of heating module 2 is lower than the set value, control valve group 32 is in the first state to connect the outlet of heating module 2 and return pipe 31, so that the hot water flowing out of heating module 2 that has not reached the set value is introduced into the upstream of heating module 2 through return pipe 31 to realize hot water return.

[0075] Of course, in other embodiments, the other end of the return pipe 31 can also be directly connected to the heating module 2, so that the hot water flowing out of the heating module 2 that has not reached the set value can be introduced into the heating module 2 through the return pipe 31 to achieve reheating.

[0076] In some embodiments, the control valve assembly 32 also has a second state in which the outlet of the heating module 2 and the hot water intake end 41 are connected. The control valve assembly 32 is in the second state based on the fact that the outlet water temperature of the heating module 2 is equal to the set value.

[0077] When the outlet water temperature of heating module 2 equals the set value, control valve group 32 is in the second state to connect heating module 2 and hot water outlet 41, so that the hot water taken by the user through hot water outlet 41 is kept at the required set value. Therefore, the water purifier and heat pump of this application will open the backflow mode when the hot water does not meet the water demand until the hot water equals the set value before connecting hot water outlet 41. This ensures that the hot water flowing to hot water outlet 41 is always at the set value, so that the user can take it directly and reduce the waiting time for water.

[0078] In some embodiments, the integrated water purifier and heater also includes a temperature sensor 23, which is used to detect the outlet water temperature of the heating module 2. Based on the temperature sensor 23 detecting that the outlet water temperature of the heating module 2 is lower than a set value, the control valve group 32 is controlled to switch to a first state.

[0079] Temperature sensor 23 can detect the hot water temperature of heating module 2 in a timely manner. When the outlet water temperature of heating module 2 is detected to be lower than the set value, the control valve group 32 is switched to the first state to automatically start the hot water recirculation mode and improve control efficiency.

[0080] In some embodiments, based on the temperature sensor 23 detecting that the outlet water temperature of the heating module 2 is equal to a set value, the control valve group 32 is controlled to switch to the second state.

[0081] When the temperature sensor 23 detects that the outlet water temperature of the heating module 2 is equal to the set value, it controls the control valve group 32 to switch to the second state to automatically connect the heating module 2 and the hot water inlet 41, so that users can conveniently obtain hot water at the required temperature and improve control efficiency.

[0082] Specifically, the controller controls the switching of the control valve group 32. The temperature sensor 23 feeds back the information that the outlet water temperature of the heating module 2 is lower than the set value to the controller. The controller controls the control valve group 32 to switch to the first state based on the feedback information. The temperature sensor 23 feeds back the information that the outlet water temperature of the heating module 2 is equal to the set value to the controller. The controller controls the control valve group 32 to switch to the second state based on the feedback information.

[0083] like Figure 5 and Figure 6 As shown, in some embodiments, the control valve assembly 32 includes a valve inlet 321, a first valve outlet 322, and a second valve outlet 323. The valve inlet 321 is connected to the outlet of the heating module 2, the first valve outlet 322 is connected to the return pipe 31, and the second valve outlet 323 is connected to the hot water intake end 41. When the control valve assembly 32 is in a first state, the valve inlet 321 and the first valve outlet 322 are connected. When the control valve assembly 32 is in a second state, the valve inlet 321 and the second valve outlet 323 are connected.

[0084] When the outlet water temperature of heating module 2 is detected to be lower than the set value, the control valve group 32 is switched to the first state to connect the valve inlet 321 and the first valve outlet 322. The hot water flowing out of heating module 2 that has not reached the set value flows through valve inlet 321, first valve outlet 322 and return pipe 31 and is introduced upstream of heating module 2 to realize hot water return for reheating.

[0085] When the water temperature at the outlet of the heating module 2 is detected to be equal to the set value, the control valve group 32 is switched to the second state to connect the valve inlet 321 and the second valve outlet 323. The hot water flowing out of the heating module 2 that has reached the set value flows through the valve inlet 321 and the second valve outlet 323 and then flows to the hot water intake end 41 for the user to use.

[0086] Regarding the type of control valve assembly 32, in some embodiments, the control valve assembly 32 is a stepless regulating valve, which can control the opening degree of the second valve outlet 323 to regulate the water flow rate.

[0087] By setting the control valve assembly 32 as a stepless regulating valve, the regulation accuracy can be ensured, and the opening degree of the second valve outlet 323 can be adjusted, thereby achieving the regulation of the water flow rate.

[0088] It should be noted that the working principle of a stepless control valve is to drive the valve core to make continuous or segmented linear movements within the valve body through an actuator (such as an electric actuator or a pneumatic actuator), thereby changing the flow area between the valve core and the valve seat and achieving precise regulation of parameters such as fluid flow rate and pressure.

[0089] In some embodiments, the heating module 2 includes a hot water pipe 21 and a heating unit 22 disposed on the hot water pipe 21. One end of the hot water pipe 21 is connected to the outlet end of the water supply pipe 11, and the other end of the hot water pipe 21 is connected to the hot water intake end 41. One end of the return pipe 31 is connected to the hot water pipe 21 upstream of the heating unit 22.

[0090] Pure water flowing out of the outlet 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 the set value, it flows to the hot water intake end 41 for the user to use. If the hot water is not heated to the set value, it flows back into the hot water pipeline 21 upstream of the heating unit 22 through the return pipeline 31 for return.

[0091] Preferably, the heating unit 22 can be a heating element, which can achieve instantaneous and rapid heating of water, but is not limited to this.

[0092] For example, in other embodiments, the heating unit 22 may also be an electric heating wire or a heating rod, etc.

[0093] The temperature sensor 23 can be a temperature sensing element 113, which is installed on the hot water pipe 21 downstream of the heating unit 22 to detect the hot water flowing out of the heating unit 22, but is not limited to this.

[0094] For example, in other embodiments, the temperature sensor 23 can also be directly disposed on the heating unit 22, which can also realize the detection of the outlet water temperature of the heating unit 22.

[0095] In addition to the above-mentioned settings, in some embodiments, the heating module 2 also includes a second solenoid valve 211. The second solenoid valve 211 is disposed in the hot water pipe 21 and is used to control the opening and closing of the hot water pipe 21. When the second solenoid valve 211 is opened, the heating module 2 is started, and pure water flows through the hot water pipe 21 into the heating unit 22 for heating.

[0096] In some embodiments, the heating module 2 further includes a zero-pressure valve 212, which is disposed in the hot water pipe 21 and is located downstream of the second solenoid valve 211.

[0097] In some embodiments, the heating module 2 further includes a water pump 213, which is disposed in the hot water pipe 21 and is located downstream of the zero-pressure valve 212. The water pump 213 provides power for the flow of water so that the pure water flowing out of the water purification system 1 flows into the hot water pipe 21.

[0098] In some embodiments, the first sterilization module 5 is located downstream of the control valve assembly 32.

[0099] Due to the setting of the control valve group 32, the control valve group 32 will inevitably cause a certain degree of pollution to the water source. Therefore, by setting the first sterilization module 5 downstream of the control valve group 32, the hot water flowing out of the control valve group 32 can be disinfected and sterilized to ensure drinking water health.

[0100] In some embodiments, the integrated water purifier and heater also includes a room temperature water outlet module 6, which is connected to the outlet of the water purification system 1 and to the room temperature water intake end 42.

[0101] By setting up a room temperature water outlet module 6, when a user needs to take room temperature water, the pure water flowing out of the water purification system 1 flows through the room temperature water outlet module 6 to the room temperature water intake end 42, and the user can take room temperature water from the room temperature water intake end 42, thus meeting different water needs.

[0102] The ambient temperature water outlet module 6 includes an ambient temperature water pipeline 61 and a third solenoid valve 62. One end of the ambient temperature water pipeline 61 is connected to the outlet end of the water production pipeline 11, and the other end of the ambient temperature water pipeline 61 is connected to the ambient temperature water intake end 42. The third solenoid valve 62 is installed in the ambient temperature water pipeline 61.

[0103] When a user needs room temperature water, the third solenoid valve 62 is opened, and the second solenoid valve 211 is closed. The pure water flowing from the outlet of the water pipe 11 flows from the room temperature water pipe 61 to the room temperature water intake end 42 for the user's use.

[0104] In some embodiments, the integrated water purifier and heat pump also includes a water outlet 4, with a hot water inlet 41 and a room temperature water inlet 42 both located at the water outlet 4.

[0105] In some embodiments, the integrated water purifier and heater further includes a second sterilization module 7, which is disposed on the ambient temperature water outlet module 6 and is located near the ambient temperature water inlet 42.

[0106] The second sterilization module 7 can disinfect and sterilize the room temperature water flowing out of the warm water outlet module to improve water safety.

[0107] Specifically, the second sterilization module 7 is installed in the ambient temperature water pipe 61 to disinfect and sterilize the ambient temperature water flowing through the ambient temperature water pipe 61.

[0108] Both the first sterilization module 5 and the second sterilization module 7 can be ultraviolet sterilization devices, which eliminate microorganisms and bacteria in the water through ultraviolet light, but are not limited to this.

[0109] In some embodiments, the first sterilization module 5 and the second sterilization module 7 can be integrated into the same housing to improve structural compactness.

[0110] To facilitate understanding of the integrated air purifier and heating unit in this embodiment, the usage process of the integrated air purifier and heating unit will now be described in conjunction with the accompanying drawings:

[0111] When the heating module 2 or the ambient temperature water outlet module 6 is running, the water purification system 1 will also operate to purify the raw water into pure water before it flows to the heating module 2 or the ambient temperature water outlet module 6 for the user to use.

[0112] like Figures 1 to 4 As shown, when the water purification system 1 is running: raw water (tap water) flows in from the raw water inlet and is first pre-treated by the pre-filter 12 to filter out impurities such as mud, rust, and solid pollutants in the water. Then, it flows into the fine filter 13 through the water production pipeline 11 for filtration to filter out bacteria, viruses, and other small pollutants in the water. The filtered water flows out from the pure water outlet 132 and is further filtered by the post-filter 14 to adsorb residual odors and discoloration in the water, improve the taste, and obtain pure water. Finally, it is discharged from the outlet of the water production pipeline 11 into the heating module 2 for heating or the room temperature water intake module for users to use.

[0113] like Figure 1 and Figure 5 , Figure 6As shown, when a user needs hot water, the heating module 2 operates, the second solenoid valve 211 opens, and the third solenoid valve 62 closes. Pure water flows from the water production pipeline 11 into the hot water pipeline 21, and then flows sequentially through the second solenoid valve 211, the zero-pressure valve 212, and the water pump 213 before entering the heating unit 22 for heating. The temperature sensor 23 monitors the hot water temperature in real time. When the hot water temperature is lower than the set value, the control valve group 32 switches to the first state, so that the valve inlet 321 and the first valve outlet 322 are connected, and the hot water flowing out of the heating module 2 that has not reached the set value... After passing through the valve inlet 321, the first valve outlet 322, and the return pipe 31, the hot water is introduced upstream of the heating module 2 to achieve hot water return for reheating. When the outlet water temperature of the heating module 2 is detected to be equal to the set value, the control valve group 32 is switched to the second state to connect the valve inlet 321 and the second valve outlet 323. The hot water flowing out of the heating module 2 that has reached the set value flows through the valve inlet 321 and the second valve outlet 323 and then flows through the first sterilization module 5. After being disinfected and sterilized by the first sterilization module 5, it flows to the hot water intake end 41 for the user to use.

[0114] like Figure 1 and Figure 2 As shown, during the operation of the heating module 2, the pressure relief module 20 is in operation, that is, the pressure relief valve 202 and the pressure relief solenoid valve 203 are both open. A portion of the purified water flowing out from the fine filter element 13 flows back to the water production pipeline 11 at the front end of the pressure stabilizing pump 19 through the pressure relief branch 201 and mixes with the raw water before flowing back into the fine filter element 13 for filtration again, thereby avoiding excessive pressure at the outlet of the water production pipeline 11 that could damage the pipeline.

[0115] When a user needs to take room temperature water, the room temperature water outlet module 6 is activated, the third solenoid valve 62 is opened and the second solenoid valve 211 is closed, and the pure water flowing out of the water outlet of the water production pipeline 11 flows through the room temperature water pipeline 61 and through the second sterilization module 7. After being disinfected and sterilized by the second sterilization module 7, it flows to the room temperature water intake end 42 for the user's use.

[0116] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
