This increases the heat dissipation area and improves heat dissipation efficiency, effectively collecting and dissipating the heat generated by the heat tank cavity. Furthermore, the heat insulation structure and housing assembly separate the heat dissipation cavity from the filter cavity, preventing air convection between the filter cavity and the heat tank cavity. This avoids the heat radiation from the heat tank assembly affecting the temperature rise of the filtration system within the filter cavity, preventing the room-temperature water in the filtration system from being heated excessively, and also preventing the filter element from experiencing reduced lifespan due to heat radiation. This reduces the impact of heat generated during heating on the filtration system, improving its lifespan and safety, and enhancing the user experience. Attached Figure Description

[0046] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0051] With economic development and improved living standards, consumers are paying more and more attention to healthy drinking water and have increasingly higher requirements for water usage. As a water treatment device that can deeply filter, purify, and heat water according to usage requirements, the integrated water purifier and heater is gaining increasing recognition and favor from consumers.

[0052] The working principle of an integrated water purifier and heater is as follows: Water first enters the filtration system within the unit and undergoes initial filtration (e.g., using a filter screen) to remove larger impurities. The water then passes through a secondary filtration system (e.g., using activated carbon and a semi-permeable membrane) to further remove impurities and odors, ensuring water purity. Afterward, the purified water is heated to the user-set temperature using rapid heating technology. This heating process can vary depending on the heating method, primarily including instant heating and storage heating (including hot tank heating and heat-concentrating, antibacterial heating).

[0053] In related technologies, the integrated water purifier and heater is equipped with a heating tank component for heating water. During the heating process, the heat from the heating tank component will radiate inside the integrated water purifier and heater. This can easily cause the internal electronic control components to overheat and be damaged. The heat radiation from the heating tank component will also cause the room temperature water in the filtration system to rise, reducing the user experience.

[0054] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3 This application proposes an integrated air purifier and heat pump 1. In the embodiments of this application, the integrated air purifier and heat pump 1 includes a housing assembly 10, a heat insulation structure 17, a filtration system 50, a heat tank assembly 20, and an electrical control assembly.

[0055] To ensure structural strength and effectively support the internal components, the housing assembly 10 can be made of materials such as ceramic or stainless steel. The housing assembly 10 includes an outer shell and a middle shell 11 housed within it. The middle shell 11 is connected to the outer shell, and the connection between the outer shell and the middle shell 11 can be detachable or integral. The connection method includes, but is not limited to, screwing, snap-fitting, or welding. The filtration system 50, the heating tank assembly 20, and the water circuit board 60 are all mounted on the middle shell 11 for convenient installation. The heating tank assembly 20 is connected to the filtration system 50 via water circuits and is electrically connected to the electrical control assembly. The electrical control assembly includes a controller 80, a display panel 81, and an adapter 82. The electrical control assembly can be connected to the housing assembly 10 to protect it and ensure safety.

[0056] Specifically, the outer casing includes a front panel 12 and a back panel 13 arranged opposite each other in the front-to-back direction, a top panel 14 and a bottom panel 15 arranged opposite each other in the vertical direction, and two side panels 16 arranged opposite each other on the left and right sides. The front panel 12, back panel 13, top panel 14, bottom panel 15, and two side panels 16 are arranged together, and the length of the outer casing in both the front-to-back and vertical directions is greater than its length in the horizontal direction, so that the external shape of the integrated air purifier and heating unit 1 is configured as a relatively long and narrow cuboid structure. This configuration makes it easy to embed the integrated air purifier and heating unit 1 into a narrow installation space, improving the installation flexibility and adaptability of the integrated air purifier and heating unit 1. Furthermore, the cuboid structure of the integrated air purifier and heating unit 1 helps to maximize the utilization efficiency of the internal space, providing sufficient space for the various electrical components and piping assemblies inside, while maintaining a compact external size. Of course, the shape of the outer casing can also be a cube or other irregular structural form, and this application does not limit this.

[0057] It should be noted that when describing the specific location of the integrated air purifier and heating unit 1 in this application, in the actual installation process, the side of the integrated air purifier and heating unit 1 facing the user is the front side, and the side opposite to it is the rear side, which is the front-back direction of the integrated air purifier and heating unit 1; the left-right direction can be understood as the direction on the left and right sides of the integrated air purifier and heating unit 1 when the user faces the front side of the integrated air purifier and heating unit 1, and the up-down direction is the height direction of the integrated air purifier and heating unit 1.

[0058] The integrated water purifier and heater 1 typically employs a purely physical filtration method. This means the purifier and heater 1 is equipped with a filtration system 50 that contains no scale inhibitors or other chemical filtration components. Through multiple filtration technologies, it achieves deep purification with high filtration precision, effectively intercepting harmful microorganisms such as coliform bacteria, ensuring drinking water safety, and enhancing the user experience. The filtration system 50 can have a single filter element for single-stage filtration, or it can include multiple filter elements arranged in series for multi-stage filtration. In an embodiment using two-stage filter elements, the filtration system 50 is equipped with a filter element assembly, including a primary filter element 52 and a secondary filter element 53. The primary filter element 52 performs preliminary filtration, removing large particulate impurities such as sediment and rust, while the secondary filter element 53 further filters the water, removing bacteria, heavy metal particles, etc.

[0059] Specifically, the filtration system 50 may include an inlet valve 51, a primary filter element 52, a secondary filter element 53, a booster pump 55, a one-way valve 56, and a pure water outlet pipe connecting to the outlet of the filter element assembly. The inlet end of the inlet valve 51 is connected to the raw water inlet, the outlet end of the inlet valve 51 is connected to the inlet end of the primary filter element 52, the outlet end of the secondary filter element 53 is connected to the inlet end of the booster pump 55, the outlet end of the booster pump 55 is connected to the inlet end of the secondary filter element 53, the outlet end of the secondary filter element 53 is connected to the inlet end of the one-way valve 56, and the outlet end of the one-way valve 56 is connected to the outlet end of the filtration system 50.

[0060] This embodiment uses a PAC filter element as the primary filter element 52. The PAC filter element mainly uses powdered activated carbon as the filter medium. Activated carbon has an extremely high specific surface area and can effectively adsorb organic matter, chlorine, odors, pigments, and other impurities in the water. It can also remove impurities that may damage the secondary filter element 53 in advance, protecting the second filter element and extending its service life. In addition, the primary filter element 52 can also be a PP cotton filter element (polypropylene melt-blown filter element), a carbon rod filter element, a composite filter element, etc.

[0061] The secondary filter element 53 is an RO (Reverse Osmosis) filter element. Utilizing an RO membrane, it relies on the natural osmosis phenomenon of liquid passing through a semi-permeable membrane under high pressure, allowing only small water-dissolved molecules to pass through, thus separating the solute from the high-concentration solution and achieving water separation and purification. The RO membrane consists of a thin membrane layer and a supporting material. Water and chemicals in the water are allowed to pass through the semi-permeable membrane by applying operating pressure on the inlet side to overcome the natural osmotic pressure, separating water and other impurities between the semi-permeable membranes. This process removes ions, microorganisms, macromolecular compounds, and other suspended solids from the water, ensuring clean water and improving the user experience. A wastewater pipe 531 is also connected to the secondary filter element 53, and a wastewater valve 532 is installed on the wastewater pipe 531 to control wastewater discharge.

[0062] Furthermore, a water dispenser is installed between the pure water valve and the one-way valve 56. The pure water treated by the filtration system 50 flows into the water dispenser to replenish it. The water dispenser is mainly responsible for heating and cooling, providing instant hot water with multiple temperature settings. The water dispenser has high heating efficiency, achieving rapid heating in 3 seconds, and offers fast water output and precise temperature control; however, its water storage capacity is limited, resulting in a limited supply of hot water per cycle. Therefore, this application incorporates a heating tank assembly 20. A water pressure switch is also installed along the flow path of the filtered pure water into the water dispenser. The main function of the water pressure switch is to monitor the water pressure in the pipeline. When the water pressure changes, the diaphragm or corrugated tube inside the water pressure switch deforms, pushing a microswitch to close or open the circuit, thereby controlling the operation of the water pump or other related equipment. The water pressure switch has overpressure protection and underpressure protection functions, ensuring the stable operation of the integrated water purifier and heat pump 1 and preventing damage to the system due to abnormal water pressure.

[0063] In some embodiments, the integrated water purifier and heating unit 1 further includes a faucet 2, which is connected to the housing assembly 10 and communicates with the heating tank assembly 20 and the filtration system 50. When the faucet 2 is turned on, hot water from the heating tank assembly 20 or room temperature water from the filtration system 50 can flow out through the faucet 2 to provide hot or room temperature water to the user. A pure water valve is provided downstream of the flow path of the faucet 2 connected to the filtration system 50. The pure water valve is used to control the flow of filtered pure water and can turn the water flow on or off to control the supply of room temperature water. It is understood that the integrated water purifier and heating unit 1 can have two faucets 2, one of which is connected to the heating tank assembly 20 and the other is connected to the filtration system 50, so that hot water and room temperature water can be provided to the user separately.

[0064] In other embodiments, the faucet 2 can also be connected to both the heating tank assembly 20 and the filtration system 50, allowing the faucet 2 to dispense hot or room temperature water via a switch. It is understood that the faucet 2 can also be a smart faucet 2. When the controller 80 detects a signal for room temperature water dispensing or a water replenishment signal from the heating tank assembly 20 at the smart faucet 2, the controller 80 can control the filtration system 50 to start water production, ensuring that users can promptly obtain room temperature and hot water from the smart faucet 2, reducing user waiting time and improving the user experience.

[0065] In other embodiments, the filter element assembly of the filtration system 50 may further include a three-stage filter element, with the inlet of the three-stage filter element connected to the outlet of the two-stage filter element, and the outlet of the three-stage filter element connected to the outlet of the filtration system 50. The three-stage filter element is used to adsorb odors and residual chlorine, and can be used to improve the taste of room temperature water. The three-stage filter element may be an activated carbon filter element.

[0066] The housing assembly 10 is divided into a heating chamber 102 and a filter chamber 101. The filtration system 50 and the electrical control component are both located in the filter chamber 101. The heating chamber assembly 20 is located in the heating chamber 102 and is connected to the water circuit of the filtration system 50. The electrical control component is electrically connected to the heating chamber assembly 20. Water filtered by the filtration system 50 or room temperature water from the external water circuit can enter the heating chamber assembly 20 through the water circuit and be heated by the heating chamber assembly 20. The heated water can be provided to the user through the water circuit, realizing the integrated purification and heating functions of the integrated purifier and heater 1 to meet the user's needs.

[0067] Please refer to Figures 2 to 4 The technical solution of this application involves placing a heat insulation structure 17 inside the housing assembly 10, which, together with the inner wall of the housing assembly 10, forms a heat dissipation cavity 10a. The heat dissipation cavity 10a is connected to the heat tank cavity 102. The heat generated by the heat tank assembly 20 during operation, which is stored in the heat tank cavity 102, can flow into the heat dissipation cavity 10a and then be dissipated through the heat insulation structure 17. This increases the heat dissipation area and improves the heat dissipation efficiency, effectively collecting and dissipating the heat generated by the heat tank cavity 102, thus improving the heat dissipation efficiency. Furthermore, the heat insulation structure 17 and the housing assembly 10 separate the heat dissipation cavity 10a from the filter cavity 101, ensuring that the filter cavity 101 and... Air does not convect between the hot tank chambers 102, preventing heat radiation from the hot tank assembly 20 from affecting the temperature rise of the filtration system 50 and electronic control components in the filter chamber 101. This also prevents the room-temperature water in the filtration system 50 from being heated excessively, and avoids the filter element in the filtration system 50 from being affected by heat radiation, thus reducing its service life. The heat generated by the hot tank assembly 20 during heating also reduces the impact on the electronic control components, thereby reducing the risk of performance degradation or damage to the electronic control components due to heat radiation, improving the service life and safety of the filtration system 50 and the electronic control components, and enhancing the user experience.

[0068] Furthermore, the filtration system 50 and the electronic control components are jointly installed in the filtration chamber 101. That is, the filtration system 50 and the heating tank assembly 20 are both located on the same side of the heating tank assembly 20. This centralized layout of the filtration system 50 and the electronic control components optimizes space utilization, making the structural design of the integrated air purifier and heating unit 1 more compact and saving installation space. It also prevents air convection between the filtration chamber 101 and the heating tank chamber 102, while isolating the installation space of the filtration system 50 and the electronic control components from the installation space of the heating tank assembly 20, reducing structural redundancy and achieving a reasonable layout.

[0069] It should be noted that the filtration system 50 and the electronic control component can be located in the same cavity within the filtration chamber 101. Of course, the filtration chamber 101 can also include a first sub-cavity and a second sub-cavity. A mounting bracket is provided on the middle shell 11, and the mounting bracket has the first sub-cavity. The inner wall of the middle shell 11 and the outer wall of the mounting bracket enclose the second sub-cavity, so that the first sub-cavity and the second sub-cavity are separated from each other. The electronic control component can be installed on the mounting bracket and located in the first sub-cavity, and the filtration system 50 is installed on the middle shell 11 and located in the second sub-cavity. The electronic control component is further sealed to ensure safety during operation.

[0070] In some embodiments, please refer to Figures 2 to 5 The hot water tank assembly 20 includes a tank body 21 and a heating element 22. The tank body 21 has a heating chamber 210, which is connected to a water tap 2. The heating element 22 is used to heat the water in the heating chamber 210. The hot water tank assembly 20 heats room temperature water filtered by the filtration system 50 and provides hot water to the user when the water tap 2 is turned on. The tank body 21 has an inlet and an outlet 212a that are respectively connected to the heating chamber 210. The outlet 212a is located at the bottom of the tank body 21, allowing water to enter the heating chamber 210 from the bottom of the tank body 21. Heat storage is achieved by utilizing the stratification of high and low temperature water, i.e., water with different densities at different temperatures is in the upper layer of the tank body 21 due to buoyancy, while the lower density water is in the lower layer, forming a temperature transition zone between the two. This design can reduce the mixing of hot and cold water and improve heating efficiency.

[0071] In addition, the tank 21 also includes a water inlet and a water outlet, both of which are connected to the heating chamber 210. The water inlet is connected to the water supply pipe 25, so that when the water supply valve 251 is opened, the room temperature water at the outlet of the filtration system 50 can enter the heating chamber 210 through the water supply pipe 25 and the water inlet.

[0072] Specifically, such as Figure 5 As shown, the tank 21 has a length direction LL, and the heating element 22 extends along the length direction of the tank 21. It should be noted that the length direction LL of the tank 21 refers to the length of the tank 21 when a cross-section is made along the central axis of the tank 21. Similarly, the width of the cross-section is the width direction of the tank 21, and the length direction of the tank 21 is greater than the width direction of the tank 21. In the actual manufacturing process, the tank 21 can be made into a cylindrical, cuboid, or other shapes. In this case, the height direction of the tank 21 is the length direction LL of the tank 21. The heating element 22 extends along the length direction of the tank 21, which allows the heating element 22 to occupy a larger area of ​​the heating cavity 210, thereby improving the heating efficiency of the heating element 22.

[0073] In some embodiments, the heating element 22 of the hot tank assembly 20 is connected to terminals for electrical connection with the electrical control components. In this embodiment, the terminals are exposed above the tank body 21. During actual installation and maintenance, maintenance personnel can perform maintenance work by opening the top plate 14, which facilitates wiring and maintenance, especially in space-constrained environments, thus improving work efficiency. Since high-voltage terminals generate heat when current passes through them, placing the terminals above the tank body 21 helps dissipate heat and prevents heat accumulation at the bottom of the tank body 21, thus affecting the performance and lifespan of the equipment.

[0074] The housing assembly 10 is also provided with an air inlet 105 and a heat dissipation outlet 104, both of which are connected to the hot tank cavity 102. External airflow enters the hot tank cavity 102 through the air inlet 105, and after exchanging heat with the hot airflow inside the hot tank cavity 102, it flows out through the heat dissipation outlet 104. Through natural convection exhaust, external air is used to assist in heat dissipation, which can effectively dissipate the heat inside the hot tank cavity 102, so as to maintain the stability of the internal electrical components and extend their service life. It effectively avoids the safety hazards caused by excessive heat accumulation inside the hot tank cavity 102, and avoids the impact of heat radiation from the hot tank assembly 20 on the filtration system 50 and electrical control components inside the integrated heat purifier 1. At the same time, by setting the air inlet 105 and the heat dissipation outlet 104, the pressure inside and outside the hot tank cavity 102 can be balanced to prevent safety problems caused by pressure changes.

[0075] The air inlet 105 is located at the bottom of the housing assembly 10, and the heat dissipation vent 104 is located at the top of the housing assembly 10. The heat dissipation vent 104 is set higher than the heat tank assembly 20. When the terminals of the heat tank assembly 20 are located above the tank body 21, more heat will accumulate above the tank body 21 during operation. Due to the difference in density caused by the internal temperature difference of the airflow, buoyancy is formed, and the hot air will rise. In this way, through natural convection, the hot air can be efficiently discharged from the heat dissipation vent 104, reducing the accumulation of heat inside the heat tank cavity 102, thereby improving the heat dissipation efficiency and avoiding the impact of heat radiation from the heat tank assembly 20 on other electrical components inside the integrated heat and water purifier 1.

[0076] The heat dissipation vent 104 can be located on the side plate 16, the top plate 14, or the back plate 13. Similarly, the air inlet 105 can also be located on the side plate 16, the top plate 14, or the back plate 13. Specifically, the heat dissipation vent 104 and the air inlet 105 can be located together on one of the side plate 16, the top plate 14, or the back plate 13, or they can be located on two of the plates respectively, as long as the air inlet 105 is located at the bottom of the housing assembly 10 and the heat dissipation vent 104 is located at the top of the housing assembly 10. This ensures flexibility in practical applications to adapt to different installation environments. Furthermore, the shapes of the heat dissipation vent 104 and the air inlet 105 can be circular, rectangular, or other irregular shapes. The number of heat dissipation vents 104 and air inlets 105 can be one, two, three, or four, etc. This application does not limit the shape, opening size, or number of heat dissipation vents 104 and air inlets 105.

[0077] In another embodiment, a fan may also be provided inside the heat purifier 1, located inside the housing assembly 10 and near the heat dissipation vent 104. This allows the air in the heat tank cavity 102 that has been heated by the heat radiation from the heat tank assembly 20 to be forcibly discharged from the heat dissipation vent 104, increasing exhaust efficiency and further reducing the impact of heat radiation from the heat tank assembly 20 on other electrical components inside the heat purifier 1. It is understood that when the temperature inside the heat purifier 1 reaches a reasonable range, a fan may not be required for forced ventilation, and this application does not impose any restrictions on this.

[0078] In some embodiments, the heat dissipation cavity 10a is connected to the top of the heat tank cavity 102 and is located above the filter cavity 101. The heat generated by the heat tank assembly 20 during operation can be transferred to the heat dissipation cavity 10a through the connecting portion at the top, thereby achieving effective heat dissipation and reducing the impact of heat accumulation in the heat tank cavity 102 on the performance of the heat tank assembly 20. Since the heat dissipation vent 104 is located at the top of the housing assembly 10, the connection between the heat dissipation cavity 10a and the top of the heat tank cavity 102 also facilitates the flow of hot air above the heat tank assembly 20, avoiding excessive impact of hot air on the heat tank assembly 20 itself. It also facilitates the flow of hot air from the heat dissipation vent 104 located at the top of the housing assembly 10, ensuring smooth airflow, improving heat dissipation efficiency, and preventing the heat radiation from the heat tank assembly 20 during operation from affecting other electrical components inside the integrated heat purifier 1.

[0079] In some embodiments, the integrated air purifier and heat pump unit 1 further includes a water circuit board 60 disposed within the housing assembly 10. The water circuit board 60 connects the filtration system 50 and the heating tank assembly 20. Since the water circuit board 60 integrates multiple water circuit interfaces, it reduces the length of the water circuit and the number of interfaces, which helps to improve the stability of the entire water circuit system. It can also optimize the spatial layout, making the integrated air purifier and heat pump unit 1 more compact and saving installation space.

[0080] The water channel plate 60 is located between the filtration system 50 and the hot tank assembly 20, and the heat insulation structure 17, together with the water channel plate 60, separates the housing assembly 10 into the filtration chamber 101 and the hot tank chamber 102. The water channel plate 60 includes a first water channel plate 61 and a second water channel plate 62 that are connected to each other. The first water channel plate 61 is located between the filtration system 50 and the hot tank assembly 20, and the second water channel plate 62 is located between the lower surface of the hot tank assembly 20 and the inner wall of the bottom of the middle shell 11. The inner wall surfaces of the top and sides of the outer shell and the top surface of the second heat insulation member 172 enclose a heat dissipation cavity 10a; the inner wall surfaces of the middle shell 11 facing away from the second heat insulation member 172, the inner wall surfaces of the outer shell side and bottom, and the inner wall surfaces of the first water channel plate 61 and the first heat insulation member 171 facing away from the heat tank assembly 20 cooperate to form a filter cavity 101; the inner wall surfaces of the outer shell side and bottom, and the inner wall surfaces of the first water channel plate 61 and the first heat insulation member 171 facing away from the heat tank assembly 20 cooperate to form a heat tank cavity 102.

[0081] In one structural configuration, the heat insulation structure 17 includes a first heat insulation element 171 and a second heat insulation element 172. Both the first heat insulation element 171 and the second heat insulation element 172 are connected to the middle shell 11. The first heat insulation element 171 is located between the filtration system 50 and the heat tank assembly 20, and the second heat insulation element 172 is located above the filtration system 50. The inner wall surfaces of the top, side plates 16, front plate 12, and bottom plate 15 of the middle shell 11, together with the surface of the first water channel plate 61 and the side of the first heat insulation element 171 facing away from the heat tank assembly 20, form a filtration cavity 101. The inner wall surfaces of the side plates 16, top plate 14, and back plate 13, together with the surface of the first water channel plate 61 and the side of the first heat insulation element 171 facing away from the heat tank assembly 20, form a heat tank cavity 102. Furthermore, there is a gap between the upper surface of the middle shell 11 and the inner wall of the top plate 14, so that the hot airflow in the hot tank cavity 102 can flow into the heat dissipation cavity 10a through the gap and exchange heat with the heat insulation structure 17, thereby avoiding the heat radiation of the hot tank assembly 20 from causing a temperature rise effect on the filter system 50 and the electronic control components in the filter cavity 101.

[0082] In addition, by setting the water inlet on the back panel 13, the water heated by the heating tank assembly 20 can flow to the outside through the water inlet on the rear side for user use. The filter chamber 101 and the heating tank chamber 102 are set at intervals relative to each other in the front-rear direction of the integrated water purifier and heat pump 1, so that the heating tank assembly 20 is set closer to the rear side. This makes it easier to arrange the pipeline, rationally plan the space, and make the layout more compact and beautiful.

[0083] It is understood that the internal water circuit design of the integrated water purifier and heat dissipation unit 1 in this application embodiment may not use a water circuit board 60. Instead, it may integrate multiple water circuit interfaces and control components (such as inlet water valve, waste water valve, flow meter, check valve 56, and high-pressure switch) into one unit, reducing the use of water pipes and connectors, simplifying the water circuit system, reducing the risk of leakage, and improving production efficiency and cost-effectiveness. Alternatively, it may utilize a modular splicing water circuit, which includes multiple independent water circuit board 60 modules, each equipped with water circuit pipes. This design can be combined and installed as needed, providing flexibility and ease of maintenance. This application does not impose any limitations on this.

[0084] Since the terminals are exposed above the tank 21, a passage 103 is provided between the water circuit board 60 and the shell assembly 10 for the wires between the heating tank assembly 20 and the electrical control assembly to pass through, in order to facilitate the wiring layout. Specifically, the passage 103 is defined between the upper wall surface of the top of the first water circuit board 61 and the lower wall surface of the top of the middle shell 11, so that the wires between the heating tank assembly 20 and the electrical control assembly can be routed from above the water circuit board 60, and the terminals of the heating tank assembly 20 are also located above the tank 21, which facilitates the wiring layout. The heat insulation structure 17 is provided at the passage 103 to prevent air convection between the filter chamber 101 and the heating tank chamber 102, and to prevent heat convection between the filter chamber 101 and the heating tank chamber 102 through the passage 103, thereby effectively preventing heat transfer between the two spaces and preventing the heat radiation from the heating tank assembly 20 during operation from causing a temperature rise to the filter system 50 and the electrical control assembly located in the filter chamber 101.

[0085] In the structure of the heat insulation structure 17, which includes a first heat insulation element 171 and a second heat insulation element 172, the first heat insulation element 171 is disposed at the passage 103 and is located between the middle shell 11 and the water channel plate 60. Specifically, the surface of the first heat insulation member 171 facing the hot tank assembly 20 is in contact with the surface of the first water channel plate 61 facing away from the hot tank assembly 20. The surface of the first heat insulation member 171 facing away from the hot tank assembly 20 is in contact with the surface of the middle shell 11 facing the hot tank assembly 20 in the front-back direction, so as to seal the outlet 103 between the middle shell 11 and the water channel plate 60. The second heat insulation member 172 is located above the filtration system 50, and one side surface of the second heat insulation member 172 is in contact with the surface of the middle shell 11 facing away from the filtration system 50 in the vertical direction. The other side surface of the second heat insulation member 172 is opposite to the inner wall surface of the top plate 14. There is also a gap between the upper part of the first heat insulation member 171 and the inner wall surface of the top plate 14, so that the hot airflow in the hot tank cavity 102 flows into the upper part of the filtration cavity 101 through the gap and is dissipated by the second heat insulation member 172, thereby further increasing the heat dissipation area and improving the heat dissipation efficiency.

[0086] In order to ensure that the wires between the hot tank assembly 20 and the electrical control assembly can be electrically connected through the port 103, the first heat insulation member 171 is provided with a wire hole for the wires to pass through. The wire hole can be opened in the middle of the first heat insulation member 171 or at the periphery of the first heat insulation member 171. This application does not limit this.

[0087] By setting the first heat insulation component 171 and the second heat insulation component 172, air convection between the filter chamber 101 and the hot tank chamber 102 can be prevented, and heat convection between the filter chamber 101 and the hot tank chamber 102 through the port 103 can be avoided. This prevents the heat radiation from the hot tank assembly 20 during operation from affecting the filter system 50 and the electrical control components installed in the filter chamber 101, prevents the filter system 50 and the electrical control components from being heated and rising in temperature, ensures that the water temperature in the filter system 50 will not be overheated, and improves the service life and safety of the filter system 50 and the electrical control components.

[0088] Furthermore, the surface area of ​​the second heat insulation component 172 that is in contact with the middle shell 11 can be adapted to be larger, so as to completely cover the surface of the middle shell 11 that is away from the filter system 50. This can further increase the heat dissipation area of ​​the second heat insulation component 172 and improve the heat dissipation efficiency of the heat dissipation cavity 10a, thereby further reducing the impact of heat radiation from the heat tank assembly 20 on other electrical components in the integrated heat and water purifier 1.

[0089] In some embodiments, the integrated heat purifier 1 further includes a heat insulation cover 18, which is located in the hot tank cavity 102 and covers the outside of the hot tank assembly 20. This prevents heat radiation from the hot tank assembly 20 during operation from affecting other electrical components within the integrated heat purifier 1, reduces heat loss from the hot tank assembly 20 to the surrounding environment, improves thermal efficiency, and reduces energy waste. The heat insulation cover 18 also reduces noise during operation, enhancing the user experience. The heat insulation cover 18 can be made of polyetheretherketone (PEEK), graphitized ceramics, etc., possessing high heat resistance and chemical stability, enabling it to operate for extended periods in high-temperature and corrosive environments without deformation, aging, or damage.

[0090] In some embodiments, please refer to Figure 5 and Figure 6 The tank body 21 includes a tank body 211, a top cover 212, and a bottom cover 213. The tank body 211 is connected to the top cover 212 and the bottom cover 213 respectively to enclose and form a heating chamber 210. The tank body 211, the top cover 212, and the bottom cover 213 can be processed into an integral structure by means of heat deformation, etc., or can be connected by means of welding, etc., to improve the structural strength and the airtightness of the tank body 21 and prevent leakage.

[0091] The integrated water purifier and heater 1 also includes a water pump 30 and a water outlet pipe 27. Both the pure water outlet pipe and the water outlet pipe 27 are connected to the faucet 2. The water obtained by the user through the faucet 2 after being filtered by the secondary filter element 53 can be pure water. That is, a pure water outlet pipe is connected between the secondary filter element 53 and the faucet 2. One end of the pure water outlet pipe is connected to the secondary filter element 53, and the other end has two branches. One branch delivers pure water to the heating chamber 210, and the other branch delivers pure water directly to the faucet 2, where it intersects with the water outlet pipe 27 at the faucet 2.

[0092] The outlet of the water pump 30 is connected to the outlet 212a, and the outlet pipe 27 is also connected to the outlet 212a. In this embodiment, the water pump 30 can be directly connected to the tank body 211 via screws and a sealing ring, eliminating the need for a water pipe connection. This eliminates the risk of air bubbles clogging the water pipe, effectively preventing air blockage, and resulting in a more compact structure. The water pump 30 pumps the liquid in the heating chamber 210 to the outlet pipe 27. Compared to natural flow, the water pump 30 provides a more stable and faster water flow, improving the efficiency of hot water output and preventing hot water from flowing back into the heating chamber 210. The outlet pipe 27 can be connected to the faucet 2 to deliver the hot water pumped by the water pump 30 to the faucet 2 for user use.

[0093] The heating element 22 can be installed on or near the outer wall of the tank 21 to transfer heat to the liquid in the heating chamber 210 through heat conduction, so that the liquid in the heating chamber 210 can be heated; or, the heating element 22 can be installed in the heating chamber 210 and connected to the tank 21, so that the heating element 22 can directly heat the liquid in the heating chamber 210. The heating element 22 can be in the form of an electric heating wire, etc., and this application embodiment does not specifically limit it.

[0094] In the configuration where the heating element 22 is located within the heating chamber 210 and near the bottom cover 213, the water in the tank 21 is prone to stratification due to the heating effect of the heating element 22. The cold water at the bottom is insufficiently heated, resulting in a lower water temperature at the bottom and a higher water temperature at the top. When the water pump 30 is connected to the tank 211, with the inlet located at the bottom cover 213 and the outlet 212a located at the top cover 212, the water drawn directly from near the bottom will have a lower than expected temperature for the first cup of water, affecting the consistency of the water temperature. In some embodiments, along the height direction of the tank 21, the water outlet pipe 27 passes through the tank 21 and at least partially overlaps with the heating element 22 in the height direction. That is, one end of the water outlet pipe 27 is connected to the outlet of the water pump 30, and the other end extends from the bottom cover 213 into the heating chamber 210 and exits from the top cover 212. This allows the insufficiently heated water to exchange heat with the hot water in the heating chamber 210 within the water outlet pipe 27, thereby increasing the water temperature. It can make more effective use of the heat in the heating chamber 210, reduce energy waste, improve energy efficiency, and also reduce heat loss of hot water during transportation, maintain water temperature, and mitigate the problem of low temperature in the first cup of water.

[0095] It should be noted that since there will be residual water in the water outlet pipe 27, the residual water in the water outlet pipe 27 passing through the heating chamber 210 can be reheated during the next heating. Therefore, when the user takes water at long intervals or when taking water for the first time, the residual cold water will not be directly discharged, but will be heated to improve the consistency of water temperature.

[0096] In one configuration, the tank top cover 212 is also provided with an exhaust port 241, through which a water outlet pipe 27 extends. The outer wall of the water outlet pipe 27 has a gap with the wall of the exhaust port 241. Specifically, the integrated heat and water purifier 1 also includes an exhaust pipe 24, which communicates with the heating chamber 210 through the exhaust port 241. The exhaust pipe 24 is fitted onto the water outlet pipe 27, and a gap exists between the inner wall of the exhaust pipe 24 and the outer wall of the water outlet pipe 27. This effectively allows water vapor or other gases generated during the heating process in the heating chamber 210 to be discharged outside the tank through the gap between the inner wall of the exhaust pipe 24 and the outer wall of the water outlet pipe 27, preventing excessive pressure inside the tank and ensuring safe operation of the equipment. It also simplifies the structure of the tank top cover 212, reduces the number of parts, and lowers manufacturing costs. Furthermore, after the water vapor in the heating chamber 210 is discharged from the exhaust pipe 24, the air content inside the heating chamber 210 is reduced, allowing heat to be more concentrated on the water molecules, thereby improving the heating efficiency of the tank 21.

[0097] In the structure where the water outlet pipe 27 extends through the exhaust port 241, the integrated water purifier and heater 1 also includes a three-way pipe 26. The three-way pipe 26 has an exhaust chamber and a first interface 261, a second interface 262, and a third interface 263 communicating with the exhaust chamber. The water outlet pipe 27 passes through the first interface 261 and partially extends into the second interface 262. The outer wall of the water outlet pipe 27 extending into the second interface 262 is sealed to the inner wall of the second interface 262, thereby connecting the water outlet pipe 27 and the second interface 262 and sealing the first interface 261 and the second interface 262. The outer wall of the exhaust pipe 24 is sealed to the inner wall of the first interface 261, so that the gap between the inner wall of the exhaust pipe 24 and the outer wall of the water outlet pipe 27 communicates with the third interface 263. The gas in the heating chamber 210 can be discharged sequentially through the exhaust port 241, the exhaust chamber, and the third interface 263. Specifically, the three-way pipe 26 is a three-way flexible pipe that can simultaneously fasten one end of the water outlet pipe 27 and one end of the exhaust pipe 24, avoiding welding when the water outlet pipe 27 passes through the tank top cover 212, making maintenance and replacement easier, eliminating the need for complicated welding operations, and reducing the difficulty and cost of maintenance.

[0098] In another structural form, the exhaust port 241 is connected to the faucet 2. That is, when the user needs hot water, the user opens the water outlet 212a, and the steam will be discharged first or the steam will be discharged together with the hot water. At this time, because the temperature of the steam is too high, the user may be scalded when the steam sprays out from the water outlet 212a. At the same time, when the user does not use the water purifier and heat pump 1 and a large amount of steam is generated in the heating chamber 210, a large amount of steam will flow from the exhaust pipe 24 to the water outlet 212a. The temperature at the water outlet 212a is lower than the temperature inside the heating chamber 210, so that a large amount of steam will turn into water droplets and be discharged from the water outlet 212a, resulting in water waste and frequent dripping of the water purifier and heat pump 1.

[0099] Therefore, please refer to Figures 7 to 9 The integrated water purifier and heater 1 also includes an exhaust pipe 24, a condenser pipe 28, and a water supply pipe 25. The exhaust pipe 24 is connected to the heating chamber 210 through an exhaust port 241. The exhaust pipe 24 passes through the condenser pipe 28, which has a condensation chamber capable of holding cooling water. One end of the water supply pipe 25 is connected to the tank 21 and communicates with the heating chamber 210. The other end of the water supply pipe 25 is connected to the condenser pipe 28 and communicates with the condensation chamber, allowing cooling water in the condensation chamber to flow into the heating chamber 210 through the water supply pipe 25. By setting the exhaust pipe 24 to pass through the condensation chamber of the condenser pipe 28, the water vapor from the exhaust pipe 24 is cooled by the cooling water in the condensation chamber and condenses into water droplets. These water droplets then flow back into the heating chamber 210 due to gravity, preventing water from dripping from the faucet 2 and preventing water vapor from scalding the user. This improves the safety of using the integrated water purifier and heater 1.

[0100] During the operation of the water pump 30, the local pressure drops below the vapor pressure of the liquid, causing bubbles to easily form in the water. These bubbles collapse rapidly after reaching the high-pressure area with the flow, generating shock waves and causing air blockage. Over a long period of time, this may damage the water pump 30.

[0101] In one embodiment of this application, the water outlet pipe 27 includes a connected water outlet section 271 and a water inlet section 272. The water inlet section 272 is connected to the outlet of the water pump 30 and to the water inlet. The water outlet section 271 extends from the bottom cover 213 into the heating chamber 210 and exits from the top cover 212. At least a portion of the water inlet section 272 near the water outlet 212a extends towards the water outlet 212a, and the inner diameter of the water inlet section 272 decreases from the direction away from the water outlet section 271. It should be noted that the decrease in the inner diameter of the water inlet section 272 can be continuous, that is, the inner wall of the water inlet end 272 gradually decreases from the direction away from the water outlet section 271, or it can be in a stepped form. Of course, it can also be a combination of the above two methods. For example, while maintaining an overall decreasing trend in the direction away from the water outlet section 271, a certain segment has a continuous gradual decrease, while the other two adjacent segments have a stepped extension trend. This application does not limit this. By designing the inner diameter of the water inlet section 272 of the water outlet pipe 27 to be reduced, it helps to reduce the flow rate of water in the water inlet section 272 and facilitates the rise of air bubbles through the narrowed inner wall of the water inlet section 272 into the hot tank cavity 102, reducing the sharp drop in local pressure and thus reducing the possibility of air blockage.

[0102] In addition, the integrated water purifier and heater 1 of this application can also enable users to obtain the set water temperature. That is, users can also obtain warm water with a temperature between room temperature water and hot water discharged from the hot water tank component 20 from the faucet 2.

[0103] Therefore, the integrated water purifier and heat pump 1 of this application may further include a controller 80, a first temperature sensor, and a second temperature sensor. The first temperature sensor may be installed in the tank 21 and is used to detect the temperature inside the heating chamber 210 and feed the data back to the controller 80. The second temperature sensor is installed in the pure water outlet pipe and is used to detect the temperature of the pure water in the pure water outlet pipe and feed the data back to the controller 80. The controller 80 may receive the detection values ​​of the first and second temperature sensors and, based on these temperature detection data, control the operating power of the water pump 30 and the booster pump 55 to form warm water at the set temperature value at the faucet 2, thereby realizing the adjustment of the flow rate of hot water and pure water, and finally forming water at the user-set temperature value at the faucet 2.

[0104] Specifically, the booster pump 55 is connected to the pure water outlet pipe. The booster pump 55 can be frequency-controlled or a non-frequency-controlled pump can be used. By adjusting its own duty cycle, the operating power is controlled, thereby outputting different pure water flow rates. The duty cycle can be determined by the temperature setting selected by the user. The faucet 2 serves as the water terminal, used to receive pure water from the pure water outlet pipe and hot water from the outlet pipe 27, and mix the two to form warm water at the set temperature.

[0105] In this embodiment, the controller 80 controls the operating power of the water pump 30 and the booster pump 55 by controlling their duty cycles. For example, the user selects a specific temperature setting on the operating interface of the integrated water purifier and heater 1, such as the common 45℃ or 55℃, according to their desired water temperature.

[0106] When the user selects a temperature setting, the controller 80 adjusts the duty cycle of the booster pump 55 according to a preset correspondence. For example, when the user selects a 45℃ temperature setting, the duty cycle of the booster pump 55 is set to 85%; if the user selects a 55℃ temperature setting, the duty cycle is set to 75%. Through this duty cycle adjustment, the booster pump 55 can deliver pure water to the faucet 2 at a corresponding flow rate. Adjusting the duty cycle essentially controls the operating time of the booster pump 55, thereby controlling the flow rate of pure water and ensuring that an appropriate amount of low-temperature pure water is involved in the mixing process.

[0107] While the booster pump 55 begins supplying pure water, the first temperature sensor continuously monitors the temperature of the hot water in the heating chamber 210, and the second temperature sensor simultaneously detects the temperature of the pure water in the pure water outlet pipe. These two temperature sensors acquire temperature data in real time and transmit it to the controller 80, providing temperature data for the calculation and control of the duty cycle of the subsequent water pump 30.

[0108] After receiving the detected values ​​of the pure water temperature and the hot water temperature, the controller 80 calculates the required duty cycle of the water pump 30 based on its internal preset control algorithm. According to the calculated duty cycle of the water pump 30, the controller 80 controls the water pump 30 to deliver hot water to the faucet 2 at a corresponding hot water flow rate. In this way, the flow rate of the hot water matches the predetermined flow rate of the pure water, ensuring that the two waters mix at the faucet 2 to reach the user-set temperature.

[0109] The purified water from the purified water outlet pipe and the hot water from the hot water outlet pipe 27 meet and mix thoroughly at the faucet. Because the flow rates of the purified water and hot water were adjusted in the preceding steps by controlling the duty cycles of the booster pump 55 and the water pump 30, the two waters can mix to form warm water at the set temperature based on the principles of heat transfer and mixing. For example, at the 45℃ warm water setting, after the appropriate flow rate of purified water mixes with the corresponding flow rate of hot water, a stable 45℃ warm water temperature is ultimately output from faucet 2, thus meeting the user's needs.

[0110] In some embodiments, the integrated water purifier and heater 1 further includes a detection component 23, which includes at least one of a water level detection element 232, a water quality detection element, and a temperature control element 237. The water level detection element 232, the water quality detection element, and the temperature control element 237 are all connected to the tank 21 and communicate with the heating chamber 210. The water level detection element 232 is used to detect the water level in the heating chamber 210, the water quality detection element is used to detect the mass of the water in the heating chamber 210, and the temperature control element 237 is used to detect the temperature of the water in the heating chamber 210.

[0111] Specifically, the water level detection element 232 is connected to the tank 21 and communicates with the heating chamber 210, so that the water level detection element 232 can detect the water level in the heating chamber 210. This embodiment does not specifically limit the type of water level detection element 232. For example, the water level detection element 232 can be one of a float-type water level sensor, an electrode-type water level sensor, or a capacitive water level sensor. The float-type water level sensor detects changes in water level by the up-and-down movement of a float. When the water level rises, the float rises; when the water level falls, the float falls. The movement of the float triggers a switch inside the float-type water level sensor, thereby outputting a corresponding electrical signal to the controller 80 to detect the water level in the heating chamber 210. The electrode-type water level sensor detects the water level by placing electrodes in the heating chamber 210 and utilizing the conductivity of water. When the water level rises and contacts the electrode, the circuit is activated, outputting an electrical signal to the controller 80 to detect the water level within the heating chamber 210. The capacitive water level sensor detects the water level by measuring the capacitance between the sensor and the water level. As the water level rises, the capacitance changes, resulting in a corresponding electrical signal being output to the controller 80 for further detection of the water level within the heating chamber 210.

[0112] Furthermore, in some embodiments, the water level detection element 232 includes a high water level probe 233 and a low water level probe 234, which are spaced apart on the tank top cover 212 and extend into the heating chamber 210 towards the tank bottom cover 213. It is understood that the high water level probe 233 is used to detect the position of the highest water level in the heating chamber 210, and the low water level probe 234 is used to detect the position of the lowest water level in the heating chamber 210; that is, when the liquid in the heating chamber 210 rises to the highest water level, the water supply pipe 25 stops supplying water to the heating chamber 210 to prevent the liquid in the heating chamber 210 from overflowing; when the liquid in the heating chamber 210 drops to the lowest water level, the water supply pipe 25 supplies water to the heating chamber 210 to prevent the heating chamber 210 from drying out. It should be noted that the embodiments of this application do not specifically limit the position of the high water level probe 233 and the low water level probe 234 on the tank body 21.

[0113] In another embodiment, the water level detection element 232 may include two high water level probes 233 and one low water level probe 234. The two high water level probes 233 may be disposed on the tank top cover 212, and the high water level positions detected by the two high water level probes 233 are not identical; that is, there are first and second high water level positions within the heating chamber 210, and the first high water level position is higher than the second high water level position in the height direction of the tank body 21. In this case, one high water level probe 233 is used to detect the first high water level position, and the other high water level probe 233 is used to detect the second high water level position. Even if the other high water level probe 233 malfunctions, detection can still be performed using the first high water level probe 233, thereby improving the accuracy of the high water level detection. Furthermore, the low water level probe 234 may be disposed on the tank top cover 212 or the tank bottom cover 213 to detect the lowest water level position within the heating chamber 210.

[0114] The water quality detection element is connected to the tank 21 and communicates with the heating chamber 210; that is, the water quality detection element is used to detect the quality of the liquid in the heating chamber 210 to ensure that the user is provided with safe and hygienic liquid. This application embodiment does not specifically limit the type of water quality detection element; for example, the water quality detection element can be an electrochemical sensor, a biosensor, etc.

[0115] The temperature control element 237 is connected to the tank body 21 and communicates with the heating chamber 210; that is, a portion of the temperature control element 237 extends into the heating chamber 210 so that the temperature control element 237 can detect the temperature of the liquid in the heating chamber 210. The temperature control element 237 may be disposed on the top cover 212 of the tank or on the body 211 of the tank, and this embodiment does not specifically limit the placement of the temperature control element 237.

[0116] Furthermore, in some embodiments, the temperature control element 237 includes a temperature control fixing plate and a temperature sensor. Specifically, the temperature control fixing plate is connected to the tank body 21; that is, when the temperature control element 237 is installed on the tank body 211, the temperature control fixing plate can be fixed to the tank body 211 by welding, screwing, snapping, bonding, or other methods. The temperature control fixing plate is provided with a through hole communicating with the heating chamber 210, so that the temperature sensor can extend into the heating chamber 210 through the through hole, so that the temperature sensor can detect the temperature of the liquid in the heating chamber 210. When the temperature of the liquid is too high, the controller 80 can control the heating element 22 to stop heating, thereby protecting the tank body 21.

[0117] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
