Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0063] Please refer to Figures 1 to 5 This application provides an integrated water purifier and heater 1, which is a device that integrates purification and heating functions and is typically used in water treatment. The main function of this device is to provide purified and heated water to meet people's dual needs for water quality and temperature. The integrated water purifier and heater 1 includes a housing assembly 10, a heating tank assembly 20, a water circuit board 60, a control board 80, a display board 90, an adapter 91, and a filtration system 50. The control board 80 is an important part of the control system of the integrated water purifier and heater 1, which also includes a controller.

[0064] The housing assembly 10 has an inner cavity 10a, in which the heating tank assembly 20, water circuit board 60, control board 80, display board 90, adapter 91, and filtration system 50 are all installed. The housing assembly 10 protects these structures, reducing the probability of damage to the heating tank assembly 20 and filtration system 50. It is understood that the housing assembly 10 can be made of at least one of metal and plastic. For example, the housing assembly 10 can be made of metal to give it high structural strength, reducing the probability of damage and consequently reducing the probability of damage to the heating tank assembly 20 and filtration system 50, thus extending the service life of the integrated heat and water purifier 1.

[0065] The integrated water purifier and heat pump unit 1 can be connected to a faucet 92 via a pipe. The faucet 92 can be placed in a location easily accessible to the user. The faucet 92 is connected to the heating tank assembly 20 and the filtration system 50. When the faucet 92 is turned on, hot water from the heating tank assembly 20 or purified water from the filtration system 50 can flow out through the faucet 92, providing the user with hot or purified water. A purified water valve 94 is installed downstream of the flow path of the faucet 92 connected to the filtration system 50. The purified water valve 94 is used to control the flow of filtered purified water, and can turn the water flow on or off to control the supply of purified water. It is understood that the integrated water purifier and heat pump unit 1 can have two faucets 92, one faucet 92 connected to the heating tank assembly 20 and the other faucet 92 connected to the filtration system 50, so that hot water and purified water can be provided to the user separately. In other embodiments, the faucet 92 can also be connected to the heating tank assembly 20 and the filtration system 50 respectively, and the flow of hot or purified water can be controlled by switching the faucet 92 on or off.

[0066] Understandably, faucet 92 can also be a smart faucet 92. A smart faucet 92 has a control panel, which may include buttons or a touchscreen interface. Users can use the control panel to manage their drinking water needs, such as dispensing purified water or hot water. When a user operates the faucet's control panel, the control panel sends a signal to the control board 80 located within the housing assembly 10 via an electrical connection (possibly wireless or wired). For example, if the user selects purified water, the control board 80 will activate the output of purified water filtered by the filtration system 50, which will then flow out through faucet 92. This reduces user waiting time and improves the user experience.

[0067] In other embodiments, control can also be achieved remotely via a smartphone application (APP). This smartphone application wirelessly communicates with the control system of the integrated water purifier and heater, allowing users to remotely operate and monitor the unit's operating status through the app. Through this application, users can perform various functions, such as starting or stopping the water filtration and heating process, adjusting the water temperature, monitoring filter lifespan, and receiving system status notifications.

[0068] like Figure 1 As shown, the hot water tank assembly 20 has a heating chamber 21a, which is connected to a faucet 92 and a filtration system 50. The filtration system 50 is used to supply filtered water to the heating chamber 21a of the hot water tank assembly 20. The hot water tank assembly 20 heats the pure water filtered by the filtration system 50 and provides hot water to the user after the faucet 92 is turned on.

[0069] Housing assembly 10 has filter chamber 103 (e.g. Figure 6The filtration system 50 is installed in the filter cartridge chamber 103 and is connected to a tap water pipe. The filtration system 50 includes a filter cartridge, a booster pump 70, and an inlet valve 53. Both the booster pump 70 and the inlet valve 53 are electrically connected to the control board 80. When the control board 80 receives a signal for pure water dispensing from the faucet 92 or a water replenishment signal from the heating tank assembly 20, it controls the filtration system 50 to start water production. When these two signals disappear, the control board 80 controls the filtration system 50 to stop water production and enter a standby state. The pure water from the outlet of the filtration system 50 can enter the heating tank assembly 20 or flow directly out through the faucet 92.

[0070] For example, the filtration system 50 may include multiple filter elements and a purified water pipe connecting the filter elements. The multiple filter elements may be set independently or integrated into a composite filter element. Understandably, if the multiple filter elements are set independently, the purified water pipe is connected to the filter element of the last filtration process; if the multiple filter elements are an integrated composite filter element, the purified water pipe is connected to the composite filter element. The purified water pipe can deliver pure water that can be directly consumed after filtration, and the purified water pipe is connected to the faucet 92.

[0071] like Figure 1 , Figure 5 and Figure 6 As shown, specifically, the filtration system 50 may include a first filter element 51, a second filter element 52, a booster pump 70, and a one-way valve 54. The inlet end of the inlet valve 53 is connected to the raw water inlet, the outlet end of the inlet valve 53 is connected to the inlet end of the first filter element 51, the outlet end of the first filter element 51 is connected to the inlet end of the booster pump 70, the outlet end of the booster pump 70 is connected to the inlet end of the second filter element 52, the outlet end of the second filter element 52 is connected to the inlet end of the one-way valve 54, and the outlet end of the one-way valve 54 is connected to the outlet end of the filtration system 50.

[0072] The first filter element 51 is used for preliminary filtration of raw water, removing large particles such as sediment, rust, insect eggs, and red worms. The raw water can be tap water, well water, etc. The first filter element 51 can be a PP cotton filter element (polypropylene melt-blown filter element), a carbon rod filter element, a composite filter element, or a powdered activated carbon filter element (PAC filter element). This embodiment uses a PAC filter element as an example. The PAC filter element mainly uses powdered activated carbon as the filter medium. Activated carbon has an extremely high specific surface area, effectively adsorbing organic matter, chlorine, odors, pigments, and other impurities in the water. It can also pre-remove impurities that may damage the second filter element 52, protecting the second filter element 52 and extending its service life.

[0073] The second filter element 52 contains a reverse osmosis membrane, which can be an artificial semi-permeable membrane. The membrane pore size of the reverse osmosis membrane is very small, which can effectively remove impurities such as dissolved salts, colloids, microorganisms, and organic matter in the water. That is, the second filter element 52 can be a reverse osmosis filter element (RO filter element). In order to drive water through the reverse osmosis membrane, a higher water pressure is required, so a booster pump 70 is required.

[0074] Due to the requirements of the reverse osmosis process, a certain proportion of wastewater will be generated after passing through the second filter element 52. Therefore, a wastewater pipe 521 is connected to the second filter element 52, and a wastewater valve 522 is installed on the wastewater pipe 521 to control the discharge of wastewater.

[0075] It should be noted that regularly replacing the first filter element 51 and the second filter element 52 can prevent the efficiency of the first filter element 51 and the second filter element 52 from decreasing due to long-term use. Therefore, both the first filter element 51 and the second filter element 52 are partially exposed outside the housing assembly 10, making it convenient for users to pull out the first filter element 51 and the second filter element 52 from the outside for replacement without disassembling the housing assembly 10 for complicated operations.

[0076] In other embodiments, the filtration system 50 may further include a third filter element, the inlet of which is connected to the outlet of the second filter element 52, and the outlet of the third filter element is connected to the outlet of the filtration system 50.

[0077] The third filter element is used to adsorb odors and residual chlorine, which can improve the taste of pure water. The third filter element can be an activated carbon filter element.

[0078] like Figure 1 As shown, a water dispenser 95 is further installed between the pure water valve 94 and the one-way valve 54. The pure water treated by the filtration system 50 flows into the water dispenser 95 to replenish it. The water dispenser 95 is mainly responsible for heating and cooling, providing instant hot water with multiple temperature settings. The water dispenser 95 has high heating efficiency, achieving rapid heating in 3 seconds, 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 also includes a hot water tank assembly 20.

[0079] The filtered pure water flows into the pipeline machine 95, where a water pressure switch 96 is installed. The main function of the water pressure switch 96 is to detect the water pressure in the pipeline. When the water pressure changes, the diaphragm or bellows inside the water pressure switch 96 will deform accordingly, pushing the micro switch to close or open the circuit, thereby controlling the operation of the water pump or other related equipment. The water pressure switch 96 has overpressure protection and underpressure protection functions, which can ensure the stable operation of the integrated water purification and heating machine 1 and avoid damage to the system due to abnormal water pressure.

[0080] The water circuit board 60 is a bridge connecting various water-related components inside the integrated water purifier and heat pump 1. It is responsible for guiding the water flow through the filtration system 50, the booster pump 70, etc., and finally reaching the heat tank assembly 20.

[0081] Understandably, to facilitate the replenishment of water to the heating tank assembly 20 from the outlet of the filtration system 50 and to directly supply pure water to the faucet 92, the heating tank assembly 20 may include a water supply pipe 25 and a water supply valve 251 installed on the water supply pipe 25. Specifically, the heating tank assembly 20 has a water inlet 214, which may be located at the top of the heating tank assembly 20. The water supply pipe 25 is installed at the water inlet 214 and communicates with the heating chamber 21a, so that the water replenished through the water supply pipe 25 is stored in the heating chamber 21a. When the heating tank assembly 20 needs to be replenished with water, the water supply valve 251 is opened, and pure water from the outlet of the filtration system 50 can enter the heating tank assembly 20. When the user needs to take pure water, the water supply valve 251 is closed, and pure water from the outlet of the filtration system 50 can flow out through the faucet 92.

[0082] The heating tank assembly 20 also includes a drain pipe 27 and a drain valve disposed on the drain pipe 27. Specifically, the heating tank assembly 20 has a drain outlet 217, which can be disposed at the bottom of the heating tank assembly 20. The drain pipe 27 is installed at the drain outlet 217 and communicates with the heating chamber 21a. The drain pipe 27 and the drain valve can drain the water in the heating chamber 21a under certain special circumstances, effectively solving the problem of water deterioration or dirt accumulation in the heating tank body due to prolonged disuse, thereby ensuring the drinking water safety of consumers.

[0083] like Figures 4 to 6 Furthermore, the display panel 90 is disposed adjacent to the housing assembly 10. The display panel 90 displays relevant signals through the housing assembly 10, such as the lifespan of the first filter element 51 and the second filter element 52, machine malfunctions, filter replacement operations, etc. For example, the display panel 90 can be the front panel 11 of the indicator lights. The light from the indicator lights on the display panel 90 can pass through the housing assembly 10, and the side of the housing assembly 10 opposite to the inner cavity 10a has text or images printed at the position of the corresponding indicator light to indicate the content displayed by the indicator light, so that the user can clearly understand the display content corresponding to the indicator light.

[0084] The adapter 91 can provide stable voltage and current, protecting the internal circuit of the air purifier and heating unit 1 from voltage fluctuations, extending the service life of the equipment. The adapter 91 also includes safety features such as overload protection and short circuit protection, ensuring that the power can be cut off in time in abnormal situations to protect user safety.

[0085] Please continue reading. Figures 4 to 6In some embodiments, the housing assembly 10 may be cuboid, specifically including a front plate 18 and a back plate 13 arranged opposite each other in the front-back direction, a top plate 14 and a bottom plate 15 arranged opposite each other in the vertical direction, and two side plates 16 arranged opposite each other in the left-right direction. Understandably, the front plate 18 and the back plate 13 are connected to the two side plates 16 on both sides in the left-right direction, and are connected to the top plate 14 and the bottom plate 15 on both sides in the vertical direction, while the top plate 14 and the bottom plate 15 are connected to the two side plates 16 on both sides in the left-right direction. The front plate 18, the back plate 13, the top plate 14, the bottom plate 15 and the two side plates 16 enclose and construct the aforementioned inner cavity 10a.

[0086] The display panel 90 is connected to the front panel 18 on the side facing the inner cavity 10a. Parts of the first filter element 51 and the second filter element 52 are exposed on the upper side of the front panel 18. Understandably, the first filter element 51 and the second filter element 52 are arranged horizontally in the front-to-back direction, while the display panel 90 is located below the first filter element 51 and the second filter element 52. The front panel 18 is typically positioned closer to the user for easy access and viewing of the display panel 90. Parts of the first filter element 51 and the second filter element 52 are removable from the filter cavity 103, with some exposed on the upper side of the front panel 18. Users can directly remove the first filter element 51 and the second filter element 52 from outside their face for replacement without disassembling the water purifier, thus improving maintenance convenience.

[0087] The back panel 13 is equipped with an exhaust port, a hot water port, a pure water port, a water dispenser port, a wastewater port, and a tap water port. By integrating multiple ports on the back panel 13, the functions are diversified. The faucet 92 can be connected to the hot water port, the pure water port, and the exhaust port through pipes. Through the special exhaust port design, the steam generated during the heating process can be effectively released. In addition, users can easily select and use different types of water through the faucet 92, which improves the convenience of use.

[0088] Furthermore, the housing assembly 10 also includes a panel 11, which covers the aforementioned front panel 18 and serves a protective and decorative function. The panel 11 can be designed to coordinate with the appearance of the top panel 14 and the side panel 16, thereby enhancing the overall aesthetics of the integrated air purifier and heat pump unit 1.

[0089] The housing assembly 10 also includes a middle shell 12 vertically connected to the front plate 18 and the back plate 13 in the front-rear direction. The middle shell 12 is installed in the inner cavity 10a and has a filter element cavity 103 for installing the first filter element 51 and the second filter element 52. The water channel plate 60 is vertically installed on the middle shell 12 in the left-right direction and separates the front and rear sides of the middle shell 12 to form a filter element installation space and a hot tank cavity 102, respectively. The control board 80 and the adapter 91 are both installed in the filter element installation space. The adapter 91 is located above the control board 80 and is arranged in the front-rear direction in the length direction, while the control board 80 is arranged in the up-down direction in the length direction. The hot tank assembly 20 is installed in the hot tank cavity 102. The relatively independent filter element cavity 103 and hot tank cavity 102 are set to install the filter element and the hot tank assembly 20 respectively, which can prevent the heat of the hot tank assembly 20 from affecting the filter element.

[0090] The water circuit board 60 includes two sub-water circuit boards 60. The two sub-water circuit boards 60 are assembled into one piece by screws and sealing rings. This can reduce costs and facilitate later design modifications while achieving functionality, and also make the structure of the water circuit board 60 compact.

[0091] like Figure 5 and Figure 6 As shown, further, in order to prevent the temperature of the side of the filter element near the hot tank assembly 20 from being affected and rising, the housing assembly 10 also has a heat dissipation cavity 101. The heat dissipation cavity 101 is connected to the hot tank cavity 102 and is located at the top near the filter element cavity 103. The integrated heat purifier 1 also includes a heat insulation component 93. Multiple heat insulation components 93 can be provided. For example, one heat insulation component 93 is installed between the hot tank cavity 102 and the filter element cavity 103. The main function of this heat insulation component 93 is to prevent the heat generated by the hot tank assembly 20 from being directly transferred to the filter element cavity 103, thereby protecting the filter element from high temperature and ensuring that the filter element works at a suitable temperature to maintain its filtration performance and service life. Another heat insulation component 93 is installed between the heat dissipation cavity 101 and the filter element cavity 103, and is located on the side close to the hot tank cavity 102. After the air heated by the hot tank assembly 20 enters the heat dissipation cavity 101, it can absorb a large amount of heat through the heat insulation component 93, reducing the flow of hot air into the filter element cavity 103, and dissipating heat through the top plate 14 with a large area, carrying away excess heat and preventing the temperature rise in the filter element cavity 103 from being too high.

[0092] The heat insulation element 93 can be heat insulation cotton, which has many tiny air pores inside. The air in these pores can prevent heat conduction, thereby reducing heat loss or inflow. It has a low thermal conductivity, effectively slowing down heat transfer. In other embodiments, the heat insulation element 93 can also be expanded perlite, foam plastic, aerogel, etc. This application does not impose any limitations on this.

[0093] Furthermore, the housing assembly 10 also includes a heat shield 17, which is connected to the middle shell 12 and partially encloses the middle shell 12 to form the hot tank cavity 102. The heat shield 17 covers a portion of the outer peripheral wall of the hot tank assembly 20. The heat shield 17 can be made of heat-insulating materials, such as urethane foam (PU) or polystyrene foam (EPS). These materials have low thermal conductivity and can effectively reduce heat transfer through the heat shield 17. The outer surface of the heat shield 17 can also be coated with a waterproof coating, such as waterproof paint or a hydrophobic coating, to make the heat shield 17 waterproof and heat-insulating.

[0094] Please see Figure 7 and Figure 8 In some embodiments, the hot tank assembly 20 includes a tank body 21, a heating element 22, and an exhaust pipe 24. The tank body 21 is the main body of the hot tank assembly 20 and is arranged vertically within the hot tank cavity 102. It has a heating chamber 21a for containing the liquid to be heated. The heating element 22 is at least partially disposed within the heating chamber 21a to heat the liquid within the heating chamber 21a. During the heating process, water vapor or gas is generated. Therefore, the tank body 21 also has an exhaust port 215 communicating with the heating chamber 21a. The exhaust pipe 24 is connected to the tank body 21 and communicates with the exhaust port 215. The exhaust pipe 24 is also connected to a faucet 92, which has an outlet to discharge the gas in the tank body 21 through the exhaust pipe 24 from the outlet. This is used to discharge the gas generated during the heating process, effectively expelling water vapor or other gases generated during heating from the tank, preventing pressure buildup inside the tank body 21, and improving the safe and stable operation of the hot tank assembly 20.

[0095] The hot tank assembly 20 also includes a detection assembly 23, which includes a mounting bracket 231 and multiple sensor units mounted on the mounting bracket 231. The mounting bracket 231 is insulated from the tank body 21 to ensure accurate sensor detection unaffected by the temperature of the tank body 21. The multiple sensor units include at least two types: those for detecting the liquid within the heating chamber 21a (i.e., the probe portion of the sensor unit extends into the heating chamber 21a), and those for detecting the state of the liquid within the heating chamber 21a, including but not limited to temperature, liquid level, and water quality. In the hot tank assembly 20, multiple different sensor units can detect different parameters, such as temperature, pressure, liquid level, and water quality. These parameters are crucial for ensuring the accuracy and safety of the heating process, aiding in diagnosing potential system malfunctions and enabling timely intervention. Multiple sensor units allow for more precise control of the heating process, preventing overheating or underheating and ensuring the quality of water heating. However, since multiple sensor units need to be mounted on the tank body 21, there is a possibility of incorrect assembly when they are installed separately.

[0096] In related technologies, multiple sensor units are typically installed separately, requiring multiple connecting plates to connect the sensor units to the tank 21. This results in a large number of components and low assembly efficiency. In this embodiment, however, multiple sensor units are integrated and mounted on a mounting bracket 231, which is then connected to the tank 21. This method offers high assembly efficiency and requires fewer components. It reduces potential instability caused by multiple independent connecting plates, and the integrated installation reduces the number of sensor units that need to be installed and calibrated individually, thereby simplifying the assembly process and improving production efficiency.

[0097] In this embodiment, at least two types of sensor units are arranged at intervals along the same horizontal direction to reduce signal interference between sensor units and improve data acquisition accuracy.

[0098] Specifically, the sensor unit includes at least two of the following: a temperature sensor 237, a water level sensor 232, a water quality sensor 236, a dissolved oxygen sensor, and a pressure sensor. The temperature sensor 237 detects the temperature of the liquid inside the heating chamber 21a, ensuring the liquid reaches the set heating temperature and preventing overheating or underheating. The water level sensor 232 detects the water level in the heating chamber 21a in real time. The water quality sensor 236 detects the water quality, ensuring the provided water meets drinking standards and issuing an alarm when the water quality drops, potentially requiring filter replacement or other treatment. The dissolved oxygen sensor measures the dissolved oxygen content in the water, detecting its freshness and quality. The pressure sensor detects the pressure inside the heating chamber 21a, preventing excessive pressure in the tank 21 from causing equipment damage or safety accidents. Through the coordinated use of these sensor units, the integrated water purifier and heater 1 can operate more intelligently, while providing a safer and more standardized operating environment.

[0099] like Figure 8As shown, in some embodiments, the sensor unit includes at least a low water level sensor 234 and a high water level sensor 233. When the water level in the heating chamber 21a drops to the detection standard of the low water level sensor 234, the low water level sensor 234 sends a signal to the control board 80 to control the heating element 22 to stop working, so as to prevent the heating element 22 from continuing to heat without water, thereby avoiding damage to the tank 21 and the heating element 22 or even causing a fire. The low water level sensor 234 can also trigger the outlet of the filtration system 50 to replenish water in the heating chamber 21a, ensuring that the integrated water purifier and heater 1 can continuously supply hot water. When the water level in the heating chamber 21a is higher than the detection standard of the high water level sensor 233, the high water level sensor 233 sends a signal to the control board 80 to control the filtration system 50 to stop replenishing water in the heating chamber 21a, preventing excessive water intake and avoiding overflow and loss due to excessive water in the heating chamber 21a. The low water level sensor 234 and the high water level sensor 233 together constitute a water level detection system, which keeps the water level in the heating chamber 21a within a safe range, while providing necessary safety protection and user feedback.

[0100] like Figure 8 and Figure 9 As shown, in some embodiments, the tank 21 includes a tank body 211, a top cover 212 connected to the top of the tank body 211, and a bottom cover 213 connected to the bottom of the tank body 211. The tank body 211 is cylindrical, and the tank body 211, top cover 212, and bottom cover 213 together form a heating chamber 21a, providing good mechanical strength and stability, ensuring that the tank body 21 is not easily deformed during heating. The mounting bracket 231 can be selectively connected to either the top cover 212 or the bottom cover 213, providing installation flexibility. The optimal installation position can be selected according to actual needs and space constraints, optimizing equipment layout and saving space, especially when installation space is limited. Different installation positions may be suitable for different application scenarios. For example, in some cases, installing the bracket on the top cover 212 may be more convenient for operation and maintenance, while in other cases, installing it on the bottom cover 213 may be more suitable.

[0101] This embodiment uses the mounting bracket 231 connected to the top cover 212 of the tank as a specific application example for illustration. The technical solution described is also applicable to the mounting bracket 231 connected to the bottom cover 213 of the tank. Please refer to this embodiment for corresponding adjustments and improvements.

[0102] like Figure 9 and Figure 10As shown, in some embodiments, the tank top cover 212 has at least two positioning holes 212a. The mounting bracket 231 includes a main body 2311 and at least two probe posts 2312. The at least two probe posts 2312 are connected to the main body 2311, and the at least two probe posts 2312 are inserted into the at least two positioning holes 212a one by one. The sensor unit passes through the probe post 2312, ensuring that the sensor unit is accurately positioned in the required position, improving the accuracy and reliability of the installation. The wire portion of the sensor unit is exposed outside the positioning hole 212a. The wire portion of the sensor unit is connected to the probe portion inside the probe post 2312. The wire portion can convert the parameters (such as temperature, humidity, pressure, etc.) detected by the probe portion into electrical signals and transmit them to the subsequent processing unit.

[0103] The main body 2311 can be selectively located on the side of the tank top cover 212 facing or away from the heating chamber 21a. When the main body 2311 is installed on the side of the tank top cover 212 facing the heating chamber 21a, the mounting bracket 231 must be assembled with the tank top cover 212 before the tank top cover 212 is joined to the tank body 211. Positioning the main body 2311 on the side of the tank top cover 212 facing the heating chamber 21a reduces the external space occupied by the main body 2311, achieving a more compact design.

[0104] With the main board 2311 mounted on the side of the tank top cover 212 facing away from the heating chamber 21a, the tank top cover 212 can be first assembled to the tank body 211, and then the mounting bracket 231 can be assembled to the tank top cover 212. Alternatively, the mounting bracket 231 can be first connected to the tank top cover 212 and then assembled to the tank body 211 as a module. The main board 2311's location on the side of the tank top cover 212 facing away from the heating chamber 21a helps reduce the impact of heat on the main board 2311, and because the main board 2311 is exposed externally, it is easier to maintain and repair. This embodiment allows for selection of the installation position according to installation requirements, providing greater flexibility and adaptability. Whether facing or facing away from the heating chamber 21a, the normal operation and maintenance of the sensor unit can be ensured.

[0105] In other embodiments, the main body 2311 may also be selectively disposed on the side of the bottom cover 213 facing or away from the heating chamber 21a, which will not be described in detail here.

[0106] The following is a specific application example of the main board body 2311 being located on the side of the tank top cover 212 facing the heating chamber 21a. The same technical solution is also applicable to the side of the tank top cover 212 where the main board body 2311 is located away from the heating chamber 21a. Please refer to this embodiment for corresponding adjustments and improvements.

[0107] Please continue reading. Figure 9and Figure 10 To achieve a tight connection between the mounting bracket 231 and the tank top cover 212, the hot tank assembly 20 also includes a connector 28. The tank top cover 212 has a connection hole 212b, and the mounting bracket 231 also includes a connecting post 2313. The connecting post 2313 is connected to the main body 2311 and is located on the side facing the heating chamber 21a, extending in the direction of the heating chamber 21a. The connecting post 2313 has a connection blind hole 2313a on the side facing the tank top cover 212. The connector 28 connects the connection hole 212b and the connection blind hole 2313a, so that the mounting bracket 231 is connected to the tank top cover 212, improving the firm connection between the mounting bracket 231 and the tank top cover 212 and enhancing the connection stability between the mounting bracket 231 and the tank top cover 212.

[0108] Because the opening direction of the blind hole 2313a is located on the side facing the top cover 212, the contact between the connector 28 and the liquid in the heating chamber 21a is reduced, effectively preventing the connector 28 from contaminating the heated liquid and keeping the liquid in the heating chamber 21a clean and pure. Furthermore, it avoids direct exposure of the connector 28 to the high-temperature environment inside the heating chamber 21a, helping to protect the connector 28 from heat and extending its service life.

[0109] In this embodiment, the connector 28 can be a screw, i.e., the blind hole 2313a is a threaded blind hole, and the screw can be threaded from above to connect the can top cover 212 and the connecting post 2313. In other embodiments, the connector 28 can also be a self-tapping screw. Understandably, before assembly, the can top cover 212 and the connecting post 2313 do not need to be provided with connecting holes 212b and connecting blind holes 2313a, respectively, because the self-tapping screw will form threads when screwed in. The threads formed by the self-tapping screw when screwed into the material can fit tightly with the material, enhancing the structural integrity of the connection.

[0110] It should be noted that the number of connecting holes 212b can be set as needed. In this embodiment, the mounting bracket 231 has a length direction, and at least two types of sensor units are arranged at intervals on the same radial direction of the tank top cover 212 and along the length direction of the mounting bracket 231. Two connecting holes 212b can be provided, respectively located on the left and right sides of the aforementioned radial direction, and are arranged in a centrally symmetrical manner. Two connecting blind holes 2313a are respectively aligned with the two connecting holes 212b and are arranged along the length direction of the mounting bracket 231 to ensure balance on the tank top cover 212 and reduce stress concentration caused by eccentric load. Understandably, in other embodiments, three, four, or even more connecting holes 212b can be provided, or they can be arranged in a circular array. This application does not limit this.

[0111] Furthermore, the main body 2311, probe post 2312, and connecting post 2313 are integrated components. This integrated design reduces the number of parts, simplifies the overall structure, and lowers assembly complexity. It also provides better overall rigidity, reducing potential deformation during operation and improving the stability and reliability of the hot tank assembly 20.

[0112] Please continue reading. Figure 9 and Figure 10 In some embodiments, the detection component 23 further includes a seal 238, which is disposed between the main body 2311 and the top cover 212. The seal 238 is used to seal the gap between the main body 2311 and the top cover 212, and has an opening opposite to the positioning hole 212a and the connecting hole 212b. Understandably, the purpose of providing the seal 238 is to prevent internal gas from overflowing from the positioning hole 212a and the connecting hole 212b. That is, the seal 238 can improve the sealing performance of the heating chamber 21a, prevent liquid overflow from the heating chamber 21a, further reduce heat loss, and improve the energy efficiency of the equipment. It can also prevent external contaminants such as dust and bacteria from entering the heating chamber 21a, maintaining a clean internal environment.

[0113] The aforementioned seal 238 can be either an integral seal 238 or a split seal 238. An integral seal 238 can evenly distribute the spring tightening force to different locations, reducing the aging rate and wear of the integral seal 238, thereby extending its service life. A split seal 238, through its split design, provides multiple sub-seals 238, each corresponding to at least two positioning holes 212a and at least one connecting hole 212b. Using a split seal 238 includes multiple sub-seals 238, allowing for individual replacement of any damaged sub-seal 238 without replacing the entire seal 238, thus reducing maintenance costs.

[0114] Furthermore, the seal 238 can be made of rubber, silicone, etc., all of which have good elasticity and flexibility, can adapt to different shapes and sizes, provide effective sealing, and can maintain its performance in high-temperature environments and withstand long-term use without being easily damaged.

[0115] Please see Figure 10In some embodiments, the heated tank assembly 20 further includes a first water pump 30 and a water outlet pipe 31, with the inlet of the first water pump 30 connected to the heating chamber 21a. In one configuration, the first water pump 30 is mounted and fixed to the side of the tank body 21, specifically with the outlet 216 located on the tank body 211. Specifically, the pump casing of the first water pump 30 is directly fixed to the tank body 211 via fasteners, and a sealing ring is provided between the pump casing and the tank body 211. Alternatively, the inlet and outlet 216 of the first water pump 30 are connected via a water pipe.

[0116] In another configuration, the first water pump 30 is mounted and fixed on the bottom cover 213 of the tank body 21, that is, the outlet 216 is opened on the bottom cover 213. Specifically, the pump casing of the first water pump 30 is directly fixedly connected to the bottom cover 213 by fasteners, and a sealing ring is provided between the pump casing and the bottom cover 213.

[0117] The outlet end of the first water pump 30 is connected to the outlet pipe 31. The first water pump 30 is used to pump the liquid in the heating chamber 21a to the outlet pipe 31. Compared with natural flow, the first water pump 30 can provide a more stable and faster water flow, improve the efficiency of hot water output, and prevent hot water from flowing back into the heating chamber 21a. The outlet pipe 31 can be connected to the faucet 92 to deliver the hot water pumped by the first water pump 30 to the faucet 92 for user use.

[0118] It should be noted that 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 heating tank component 20 from the faucet 92. To this end, the integrated water purifier and heater 1 of this application can further include a temperature detector. The sensor unit is used to detect the temperature inside the heating chamber 21a, and the temperature detector is used to detect the temperature in the purified water pipe. The controller can receive the detection values ​​of the sensor unit and the temperature detector, and control the operating power of the first water pump 30 and the booster pump 70 to form warm water with the set temperature value at the faucet 92.

[0119] Specifically, after multi-stage filtration (such as the first filter element 51 and the second filter element 52), the filtration system 50 outputs room-temperature purified water that is safe to drink directly. The temperature of the room-temperature water is detected by a temperature sensor and fed back to the controller. Room-temperature water is typically close to ambient temperature, such as 20°C. The heating chamber 21a of the hot water tank assembly 20 heats the filtered purified water through the heating element 22, outputting hot water. The temperature of the hot water is detected by a sensor unit and fed back to the controller to ensure that the hot water temperature reaches the set value (e.g., 90°C). If the user wants to obtain warm water at a target temperature, such as 60°C, the controller calculates the mixing ratio of hot water and room-temperature water according to the user's target temperature setting, so that the mixed water temperature reaches 60°C.

[0120] When a user sets the desired water temperature via the control panel of faucet 92 or a mobile app, the controller calculates the required flow ratio of hot and purified water based on this setting. The controller adjusts the hot water flow rate by controlling the operating power of the first water pump 30, thus affecting the water temperature at faucet 92. The water circuit board 60 guides the flow path of hot and room temperature water, mixing them before delivering them to faucet 92. By controlling the operating power of the booster pump 70, the flow rate of raw water entering the reverse osmosis filter can be adjusted, thus affecting the flow rate of filtered purified water. Through precise control of the operating power of the first water pump 30 and the booster pump 70, proper mixing of hot and purified water can be achieved, resulting in the output of warm water at the set temperature at faucet 92.

[0121] Please continue reading. Figure 10 The hot tank assembly 20 also includes a common water level sensor 235, which works in conjunction with a high water level sensor 233 and a low water level sensor 234. The common water level sensor 235, together with the high water level sensor 233 and the low water level sensor 234, forms a water level detection loop. This configuration not only improves the accuracy of water level detection but also enhances the stability and response speed of the hot tank assembly 20. The design of the water level detection loop allows the three sensor units to mutually verify data, ensuring the accuracy of water level control. When the common water level sensor 235 detects a change in water level, it transmits the information to the control board 80 in real time, while the high water level sensor 233 and the low water level sensor 234 serve as auxiliary sensors, triggering early warnings and implementing emergency measures.

[0122] However, since the high-level sensor 233 and the low-level sensor 234 need to form a detection loop with the common water level sensor 235, these belong to the low-voltage system. The heating element 22, on the other hand, belongs to the high-voltage system. If the high-voltage and low-voltage systems are not properly arranged, electromagnetic interference generated by the high-voltage system may affect the normal operation of the low-voltage system, leading to inaccurate water level detection. Furthermore, the water level detection loop is at risk of being damaged by the high-voltage system when it is close to the heating element 22, which could cause the water level detection loop to fail, affecting the accuracy and reliability of water level detection. Moreover, when air blockage occurs at the inlet of the first water pump 30, it may cause an increase in the resistance between the common water level sensor 235 and the low-level sensor 234. However, since the resistance changes are similar under air blockage and low water level conditions, this may lead to misjudgment, making it impossible to accurately distinguish between air blockage and low water level conditions.

[0123] To address the aforementioned issues, in this embodiment, the common water level sensor 235 is insulated from the outlet pipe 31, saving space on the tank top cover 212. Furthermore, the probe portion of the common water level sensor 235 extends into the outlet pipe 31, effectively isolating electromagnetic interference generated by the high-voltage system (such as the heating element 22), ensuring signal stability in the low-voltage system (water level detection circuit), and improving the accuracy of water level detection. Moreover, the probe portion of the common water level sensor 235, extending into the outlet pipe 31 and away from the heating element 22, reduces the risk of electrical breakdown due to high-voltage system failures, ensuring the long-term stable operation of the water level detection circuit.

[0124] Furthermore, when the common water level sensor 235 detects an increase in resistance, the control system receives this signal and determines that an airlock may have occurred. Upon airlock occurrence, the integrated water purifier and heater 1 automatically stops the first water pump 30, allowing the air bubbles in the airlock to dissipate naturally, thus clearing the blockage. After shutdown, the control system rechecks the resistance value between the common water level sensor 235 and the low water level sensor 234. If the recheck shows a high resistance value, it indicates that the water level in the tank 21 has reached a low level, and the system shuts down normally to prevent the first water pump 30 from running dry. If the resistance value returns to a low value, the control system determines it is an airlock, and the first water pump 30 will continue to operate normally. This design effectively distinguishes between airlock and actual low water level conditions, avoiding misjudgments and potential damage to the first water pump 30 caused by airlock. The common water level sensor 235's location within the outlet pipe 31 allows it to directly detect the operating status of the first water pump 30, improving the accuracy of water level detection. This combined use enhances the adaptability and fault diagnosis capabilities of the hot tank assembly 20, improving its overall operating efficiency and reliability.

[0125] The heating element 22 is typically located inside the heating chamber 21a on the side near the bottom cover 213. Due to the heating effect of the heating element 22, the water inside the tank 21 is prone to stratification, with insufficient heating of the cold water at the bottom, resulting in a lower water temperature at the bottom and a higher water temperature at the top. When the first water pump 30 is located on or near the bottom cover 213, it directly draws water from the bottom, which can cause the temperature of the first cup of water to be lower than expected, affecting the consistency of the water temperature.

[0126] like Figure 11As shown, in some embodiments, along the height direction of the tank body 21, a portion of the water outlet pipe 31 passes through the heating chamber 21a and extends out of the tank top cover 212. That is, a portion of the water outlet pipe 31 is connected to the outside of the tank body 21. However, by bending the pipe, a portion of the water outlet pipe 31 can pass through the heating chamber 21a, allowing insufficiently heated water to exchange heat with the hot water in the heating chamber 21a, thereby increasing the water temperature. This allows for more efficient utilization of the heat in the heating chamber 21a, reducing energy waste and improving energy efficiency. It also reduces heat loss during hot water transportation, maintains the water temperature, and mitigates the problem of low initial water temperature.

[0127] It should be noted that since there will be residual water in the water outlet pipe 31, the residual water in the water outlet pipe 31 passing through the heating chamber 21a 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.

[0128] If the exhaust pipe 24 and the water outlet pipe 31 intersect and connect, steam may spray from the faucet 92 when hot water is dispensed. This phenomenon usually occurs because the hot water flow carries the water vapor in the exhaust pipe 24 out with it, causing the user to experience not only hot water but also steam spraying out when using the faucet 92, affecting the user experience and potentially causing safety hazards.

[0129] To solve the above problems, such as Figure 10 As shown, in some embodiments, a condenser pipe 29 is connected to the exhaust pipe 24, which liquefies the water vapor inside the exhaust pipe 24. The condenser pipe 29 is vertically positioned above the tank top cover 212. When the water vapor liquefies, it flows along the wall of the condenser pipe 29 into the exhaust pipe 24 and then into the heating chamber 21a, reducing the amount of water vapor emitted and thus reducing the problem of steam spraying from the faucet 92 when the user obtains hot water. Furthermore, the liquefied water in the exhaust pipe 24 flows back into the heating chamber 21a, effectively increasing the water volume in the heating chamber 21a and reducing water waste.

[0130] It should be noted that the inner diameter of the condenser tube 29 is greater than 8mm, which is greater than the inner diameter of the exhaust tube 24. The larger inner diameter of the condenser tube 29 can increase the contact area of ​​the flowing gas, enhance convective heat transfer, improve condensation heat exchange performance, increase the liquefaction effect of the gas flowing through the condenser tube 29, and reduce the gas spray phenomenon of the faucet 92.

[0131] Please continue reading. Figure 10 In one configuration, the condenser 29 and the exhaust pipe 24 are connected in sequence, with the condenser 29 located above the exhaust pipe 24, so that the gas from the exhaust pipe 24 will be condensed by the condenser 29 before reaching the faucet 92.

[0132] like Figure 14 As shown, in another configuration, the condenser tube 29 is covered by the outer peripheral wall of the exhaust pipe 24, that is, the exhaust pipe 24 is inserted into the condenser tube 29, and part of the outer peripheral wall of the condenser tube 29 is spaced apart from the exhaust pipe 24. The condenser tube 29 is connected to the water supply pipe 25, so that the pure water in the water supply pipe 25 can first flow between the condenser tube 29 and the exhaust pipe 24, and then flow into the heating chamber 21a. By using the pure water to exchange heat with the high-temperature water vapor in the exhaust pipe 24, the water vapor can be effectively condensed. The pure water is preheated when it flows through the condenser tube 29. The preheated water enters the heating chamber 21a, which can reduce the time required to heat to the set temperature, further improve thermal efficiency, and reduce heat waste.

[0133] It should be noted that the water supply pipe 25 is inserted into the top cover 212 of the tank and extends more than 3mm toward the heating chamber 21a. The extended water supply pipe 25 can prevent water backflow because the extended part will form a certain height difference in the water supply pipe 25, so that the water cannot flow back through the siphon effect.

[0134] like Figure 15 and Figure 16 As shown, in another configuration, the portion of the water outlet pipe 31 extending from the tank top cover 212 passes through and communicates with the exhaust pipe 24. The water outlet pipe 31 and the exhaust pipe 24 are spaced apart to form an air venting channel. The hot tank assembly 20 also includes a three-way pipe 26, which has a first interface 261, a second interface 262, and a third interface 263. The first interface 261 is connected to the exhaust pipe 24, the second interface 262 is connected to and communicates with the water outlet pipe 31 extending from the exhaust pipe 24, and the third interface... 263 is connected to the gas outlet channel. The gas in the heating chamber 21a is discharged from the third interface 263. The three-way pipe 26 is a three-way flexible pipe that can simultaneously fasten the ring around one end of the water outlet pipe 31 and one end of the exhaust pipe 24 to prevent the gas in the heating chamber 21a from entering the hot water outlet channel through the gap between the water outlet pipe 31 and the second interface 262. In addition, the three-way pipe 26 can avoid welding when the water outlet pipe 31 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.

[0135] like Figure 11As shown, to reduce the occurrence of low initial water temperature, in some embodiments, the tank body 211 has a water inlet 216 connecting the inlet of the first water pump 30 and the heating chamber 21a. The water outlet 216 is positioned higher than the bottom of the heating element 22 along the height direction of the tank body 21. During the heating process, water may stratify due to density differences, with hotter water rising and colder water sinking. If the water outlet 216 is located at the bottom of the heating element 22, it may draw out the unheated cold water layer. Setting the water outlet 216 above the bottom of the heating element 22 helps to draw water from the better mixed upper and middle layers. That is, the higher position of the water outlet 216 ensures that the hotter water in the heating chamber 21a is drawn first when drawing water, reducing the problem of low initial water temperature.

[0136] In some embodiments, such as Figure 8 As shown, the heating element 22 includes a heating tube 222 and two terminals 221. The two terminals 221 are respectively connected to the two ends of the heating tube 222. The terminals 221 extend to the outside of the tank body 21 to connect to an external power source, making it easier to connect and disconnect the heating tube 222. The plane where the bottom end of the heating tube 222 is located is basically parallel to the bottom cover 213 of the tank, so that the bottom end of the heating tube 222 can be placed as close as possible to the bottom cover 213 of the tank. Unlike the related technology, where the heating tube 222 is spirally inclined and coiled in the heating chamber 21a, resulting in a large distance between the bottom end of the heating tube 222 and the bottom cover 213, the heating tube 222 in this embodiment can be placed closer to the bottom of the tank body 21, so that the cold water at the bottom can be fully heated, thereby reducing the phenomenon of cold water stratification and making the water temperature in the entire tank body 21 more uniform. The temperature of the first cup of water will be increased, avoiding the problem of low water temperature in the first cup of water caused by the direct flow of cold water from the bottom.

[0137] like Figure 1 , Figure 12 and Figure 13 As shown, in one embodiment, the hot tank assembly 20 further includes a return pipe 291, which is connected to the top cover 212 and communicates with the heating chamber 21a. The return pipe 291 also intersects and communicates with the outlet pipe 31. The first water pump 30 can pump out the liquid in the heating chamber 21a near the bottom cover 213. A reversing valve is provided between the return pipe 291 and the outlet pipe 31. The liquid that has just been pumped out may not reach the target temperature. By connecting the outlet of the first water pump 30 with the return pipe 291 through the reversing valve, the liquid flows back into the heating chamber 21a for reheating. When the preset time is reached, the hotter liquid can be delivered to the faucet 92 for the user to drink by connecting the outlet of the first water pump 30 with the outlet pipe 31 through the reversing valve.

[0138] Understandably, in another embodiment, a reversing valve may not be provided, i.e., the return pipe 291 and the outlet pipe 31 are separate water circuits. The heating tank assembly 20 is equipped with a second water pump 292, which is connected to the tank bottom cover 213. The inlet of the second water pump 292 is connected to the heating chamber 21a and is used to pump out the liquid in the heating chamber 21a near the tank bottom cover 213. One end of the return pipe 291 is connected to the outlet of the second water pump 292, and the other end is connected to the tank top cover. 212, so that the liquid flows back to the heating chamber 21a through the return pipe 291 for reheating. The second water pump 292 pumps out the liquid near the bottom cover 213 of the heating chamber 21a and then returns it to the heating chamber 21a through the return pipe 291 for reheating. This helps to improve the water temperature stratification phenomenon in the tank and make the water temperature more uniform. That is, it reduces the situation of cold water flowing out directly from the bottom. The colder water is sent back to the heating chamber 21a for heating through the return pipe 291, thereby increasing the temperature of the first cup of water.
