Such a configuration not only improves the accuracy of water level detection, but also enhances the stability and response speed of the hot tank assembly. However, since the high water level sensor and the low water level sensor need to form a detection loop with the common water level sensor, these belong to the weak current system. The heating element belongs to the strong current system. If the strong and weak currents are not arranged reasonably, the electromagnetic interference generated by the strong current may affect the normal operation of the weak current system, resulting in inaccurate water level detection. In this embodiment, the common water level sensor is insulated from the water outlet pipe, saving space on the tank top cover, and the probe part of the common water level sensor extends into the water outlet pipe, which can effectively isolate the electromagnetic interference generated by the strong current system (such as the heating element), ensure the signal stability of the weak current system (water level detection loop), and improve the accuracy of water level detection.

[0065] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0066] Please refer to Figures 1 to 5The embodiment of the present application provides a water purification and heating all-in-one machine 1, which is a device that integrates purification and heating functions and is generally used for 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 water purification and heating all-in-one machine 1 includes a housing assembly 10, a hot tank assembly 20, a waterway plate 60, a control panel 80, a display panel 90, an adapter 91 and a filter system 50, wherein the control panel 80 is an important part of the control system of the water purification and heating all-in-one machine 1, and the control system also includes a controller.
[0067] The housing assembly 10 has an inner cavity 10a, and the hot tank assembly 20, the waterway plate 60, the control panel 80, the display panel 90, the adapter 91 and the filter system 50 are all installed in the inner cavity 10a, so that the housing assembly 10 can protect the above structures and reduce the probability of damage to the hot tank assembly 20 and the filter system 50. It is understandable that the material of the housing assembly 10 can be at least one of metal and plastic. Exemplarily, the material of the housing assembly 10 can be metal, so that the housing assembly 10 has a higher structural strength as a whole, so as to reduce the probability of damage to the housing assembly 10, and further reduce the probability of damage to the hot tank assembly 20 and the filter system 50, so that the heat and water purifier 1 can have a longer service life.
[0068] The heat-purifying integrated machine 1 can be connected to the faucet 92 through a pipeline. The faucet 92 can be placed in a place where the user can easily access it. The faucet 92 is connected to the hot tank assembly 20 and the filtering system 50. When the faucet 92 is turned on, the hot water in the hot tank assembly 20 or the pure water in the filtering system 50 can flow out through the faucet 92 to provide hot water or pure water to the user. A pure water valve 94 is provided downstream of the flow path of the faucet 92 connected to the filtering system 50. The pure water valve 94 is used to control the flow of filtered pure water, and the water flow can be turned on or off to control the supply of pure water. It can be understood that the heat-purifying integrated machine 1 can have two faucets 92, one faucet 92 is connected to the hot tank assembly 20, and the other faucet 92 is connected to the filtering system 50, so that hot water and pure water can be provided to the user separately. In other embodiments, the faucet 92 can also be connected to the hot tank assembly 20 and the filtering system 50 respectively, and the faucet 92 is controlled by a switch to flow out hot water or pure water.
[0069] It is understandable that the faucet 92 can also be a smart faucet 92, which is provided with a control panel, which may include some buttons or a touch screen interface, and the user can operate the drinking water demand through the control panel, such as taking pure water or hot water. When the user operates on the control panel of the faucet, the control panel will send a signal to the control panel 80 disposed in the housing assembly 10 through an electrical connection (which may be wireless or wired). For example, if the user chooses to take pure water, the control panel 80 will start to output the pure water filtered by the filtration system 50, and the pure water will flow out through the faucet 92. The waiting time of the user is reduced and the user experience is improved.
[0070] In other embodiments, the water heater can be controlled remotely, i.e., by using a smartphone application (APP). The smartphone application communicates wirelessly with the control system of the water heater, allowing the user to remotely operate and monitor the working status of the water heater through the mobile phone APP. Through the application, the user can perform various functions, such as starting or stopping the water filtering and heating process, adjusting the water temperature, monitoring the filter life, and receiving system status notifications.
[0071] like Figure 1 As shown, the hot tank assembly 20 has a heating chamber 21a, which is connected to the faucet 92 and the filtering system 50. The filtering system 50 is used to provide filtered water to the heating chamber 21a of the hot tank assembly 20. The hot tank assembly 20 heats the pure water after being filtered by the filtering system 50, and provides hot water to the user after the faucet 92 is turned on.
[0072] The housing assembly 10 has a filter element cavity 103 (such as Figure 6 ), the filter system 50 is installed in the filter element cavity 103, and the filter system 50 is connected to the tap water pipe. The filter system 50 includes a filter element, a booster pump 70, and a water inlet valve 53. The booster pump 70 and the water inlet valve 53 are both electrically connected to the control board 80. When the control board 80 obtains a pure water taking signal at the faucet 92 or a water replenishment signal from the hot tank assembly 20, it controls the filter system 50 to start water production. When these two signals disappear, the control board 80 controls the filter system 50 to stop water production and enter a standby state. The pure water at the water outlet of the filter system 50 can enter the hot tank assembly 20, and can also flow out directly through the faucet 92.
[0073] Exemplarily, the filtration system 50 may include multiple filter elements and purified water pipes connected to the filter elements. The multiple filter elements may be independently provided or integrated into a composite filter element. It is understandable that if the multiple filter elements are independently provided, the purified water pipe is connected to the filter element of the last filtering 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 transport pure water that can be directly consumed after filtration, and the purified water pipe is connected to the faucet 92.
[0074] 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 water inlet end of the water inlet valve 53 is connected to the raw water inlet, the water outlet end of the water inlet valve 53 is connected to the water inlet end of the first filter element 51, the water outlet end of the first filter element 51 is connected to the water inlet end of the booster pump 70, the water outlet end of the booster pump 70 is connected to the water inlet end of the second filter element 52, the water outlet end of the second filter element 52 is connected to the water inlet end of the one-way valve 54, and the water outlet end of the one-way valve 54 is connected to the water outlet end of the filtration system 50.
[0075] The first filter element 51 is used to achieve preliminary filtration of raw water, and can filter out large particles such as mud, rust, worm eggs, and red worms in the raw water. 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, a powdered activated carbon filter element (PAC filter element), etc. This embodiment takes the 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 and can effectively absorb organic matter, chlorine, odor, pigments and other impurities in water. It can also remove impurities that may damage the second filter element 52 in advance, protect the second filter element 52, and extend its service life.
[0076] The second filter element 52 has a reverse osmosis membrane, which can be an artificial semi-permeable membrane. The pore size of the reverse osmosis membrane is very small, which can effectively remove impurities such as dissolved salts, colloids, microorganisms, organic matter, etc. 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.
[0077] Due to the needs of the reverse osmosis process, a certain proportion of waste water will be generated after passing through the second filter element 52. Therefore, a waste water pipe 521 is connected to the second filter element 52, and a waste water valve 522 is provided on the waste water pipe 521 to control the discharge of waste water.
[0078] It should be noted that regular replacement of the first filter element 51 and the second filter element 52 can prevent the first filter element 51 and the second filter element 52 from losing performance due to long-term use. Therefore, the first filter element 51 and the second filter element 52 are partially exposed outside the shell assembly 10, which is convenient for the user to pull out the first filter element 51 and the second filter element 52 from the outside for replacement without disassembling the shell assembly 10 for complicated operations.
[0079] In other embodiments, the filtration system 50 may further include a third filter element, a water inlet end of the third filter element is connected to a water outlet end of the second filter element 52 , and a water outlet end of the third filter element is connected to a water outlet end of the filtration system 50 .
[0080] The third filter element is used to absorb odor and residual chlorine, and can be used to improve the taste of pure water. The third filter element can be an activated carbon filter element.
[0081] like Figure 1 As shown, further, a pipeline machine 95 is also provided between the pure water valve 94 and the one-way valve 54. The pure water treated by the filtration system 50 partially flows into the pipeline machine 95 to replenish the pipeline machine 95. The pipeline machine 95 is mainly responsible for heating and cooling. The water is hot immediately after it comes out, and the temperature can be adjusted in multiple gears. The pipeline machine 95 has high heating efficiency, can heat up quickly in 3 seconds, has fast water output, and can accurately control the temperature; but its water storage capacity is limited, and the single hot water supply is limited. Therefore, the present application is also provided with a hot tank assembly 20.
[0082] A water pressure switch 96 is also provided on the flow path of the filtered pure water flowing into the pipeline machine 95. The main function of the water pressure switch 96 is to detect the water pressure in the pipeline. When the water pressure changes, the film or bellows in the water pressure switch 96 will deform accordingly, pushing the micro switch to close or disconnect the circuit, thereby controlling the operation of the water pump or other related equipment. The water pressure switch 96 has functions such as overpressure protection and underpressure protection, which can ensure the stable operation of the water purification and heating machine 1 and avoid damage to the system due to abnormal water pressure.
[0083] The waterway plate 60 is a bridge connecting various water-related components inside the air-purifier and heat-supplier 1 . It is responsible for guiding the water flow through the filtering system 50 , the booster pump 70 , etc., and finally reaches the hot tank assembly 20 .
[0084] It is understandable that, in order to facilitate the water outlet of the filter system 50 to replenish water for the hot tank assembly 20 and directly provide pure water to the faucet 92, the hot tank assembly 20 may include a water replenishment pipe 25 and a water replenishment valve 251 disposed on the water replenishment pipe 25. Specifically, the hot tank assembly 20 has a water inlet 214, which may be disposed at the top of the hot tank assembly 20. The water replenishment pipe 25 is installed at the water inlet 214 and communicates with the heating chamber 21a, so that the water replenished through the water replenishment pipe 25 is stored in the heating chamber 21a. When the hot tank assembly 20 needs to be replenished with water, the water replenishment valve 251 is opened, and the pure water at the water outlet of the filter system 50 can enter the hot tank assembly 20. When the user needs to take pure water, the water replenishment valve 251 is closed, and the pure water at the water outlet of the filter system 50 can flow out through the faucet 92.
[0085] The hot tank assembly 20 also includes a drain pipe 27 and a drain valve arranged on the drain pipe 27. Specifically, the hot tank assembly 20 has a drain port 217, and the drain port 217 can be arranged at the bottom of the hot tank assembly 20. The drain pipe 27 is installed at the drain port 217 and is connected to 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 in the hot tank body deteriorating or accumulating dirt due to long-term non-use, thereby ensuring the drinking water safety of consumers.
[0086] like Figures 4 to 6 Furthermore, the display panel 90 is disposed adjacent to the housing assembly 10, and the display panel 90 displays relevant signals through the housing assembly 10, such as the life of the first filter element 51 and the second filter element 52, machine failure, and core replacement operation. For example, the display panel 90 may be a front panel 11 that displays an indicator light, and the light of the indicator light on the display panel 90 may pass through the housing assembly 10, and a text or image is printed at the position corresponding to the indicator light on the side of the housing assembly 10 away from the inner cavity 10a to indicate the content displayed by the indicator light, so that the user can clearly understand the display content corresponding to the indicator light.
[0087] The adapter 91 can provide stable voltage and current to protect the internal circuit of the air conditioner and heat pump 1 from voltage fluctuations, thereby extending the service life of the equipment. The adapter 91 also includes safety features such as overload protection and short circuit protection to ensure that the power supply can be cut off in time under abnormal circumstances to protect the user's safety.
[0088] Please continue reading Figures 4 to 6 In some embodiments, the shell assembly 10 can be a cube, specifically including a front plate 18 and a back plate 13 relatively arranged in the front-to-back direction, a top plate 14 and a bottom plate 15 relatively arranged in the up-down direction, and two side plates 16 relatively arranged in the left-right direction. It can be understood that 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 up-down 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 above-mentioned inner cavity 10a.
[0089] The display panel 90 is connected to the side of the front panel 18 facing the inner cavity 10a, and parts of the first filter element 51 and the second filter element 52 are exposed on the upper side of the front panel 18. It can be understood that the first filter element 51 and the second filter element 52 are arranged horizontally in the front-to-back direction, and the display panel 90 is located below the first filter element 51 and the second filter element 52. The front panel 18 is usually placed on the side close to the user, which is convenient for the user to contact and view the display panel 90. The first filter element 51 and the second filter element 52 are partially retractable and arranged in the filter element cavity 103, and are partially exposed on the upper side of the front panel 18. The user can directly pull out the first filter element 51 and the second filter element 52 from the outside of the face for replacement without disassembling the water purifier, which improves the convenience of maintenance.
[0090] The back panel 13 is provided with an exhaust interface, a hot water interface, a pure water interface, a pipeline machine interface, a waste water interface, and a tap water interface. By integrating multiple interfaces on the back panel 13, diversified functions are achieved. The faucet 92 can be connected to the hot water interface, the pure water interface, and the exhaust interface through pipelines. Through the special exhaust interface design, the steam generated during the heating process can be effectively released, and the user can conveniently select and use different types of water through the faucet 92, thereby improving the convenience of use.
[0091] Furthermore, the shell assembly 10 also includes a panel 11, which is covered on the above-mentioned front plate 18 to play a protective and decorative role. The panel 11 can be designed to have an appearance coordinated with the top plate 14 and the side plate 16 to enhance the overall aesthetics of the air conditioner and heat machine 1.
[0092] The shell assembly 10 also includes a middle shell 12 vertically connected to the front plate 18 and the back plate 13 in the front-to-back direction. The middle shell 12 is installed in the inner cavity 10a and has the filter element cavity 103 for installing the first filter element 51 and the second filter element 52. The waterway plate 60 is vertically installed on the middle shell 12 in the left-right direction, and the front and rear sides of the middle shell 12 are separated into 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. The length direction of the adapter 91 is arranged in the front-to-back direction, while the length direction of the control board 80 is arranged in the up-down direction. The hot tank assembly 20 is installed in the hot tank cavity 102. Relatively independent filter element cavity 103 and hot tank cavity 102 are provided to respectively install the filter element and the hot tank assembly 20, which can prevent the heat of the hot tank assembly 20 from affecting the filter element.
[0093] Among them, the waterway plate 60 includes two sub-waterway plates 60, and the two sub-waterway plates 60 are assembled into one by screws and sealing rings. While realizing the function, it can reduce costs, facilitate later design changes, and realize the compactness of the waterway plate 60 structure.
[0094] like Figure 5 and Figure 6As shown, further, in order to prevent the temperature of the side of the filter element close to the hot tank assembly 20 from being affected and rising, the shell 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 near the top of the filter element cavity 103, the heat and air purifier 1 also includes a heat insulation member 93, and multiple heat insulation members 93 can be provided. Exemplarily, a heat insulation member 93 is installed between the hot tank cavity 102 and the filter element cavity 103. The main function of this heat insulation member 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 being affected by high temperature, ensuring that the filter element works at an appropriate temperature, and maintaining its filtering performance and service life. Another heat insulating member 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, a large amount of heat can be absorbed by the heat insulating member 93, thereby reducing the flow of hot air into the filter element cavity 103, and dissipating heat through the top plate 14 with a large area, thereby taking away excess heat and preventing the temperature in the filter element cavity 103 from rising too high.
[0095] Among them, the heat insulating member 93 can be a heat insulating cotton, and the heat insulating cotton has many tiny gas holes inside. The air in these pores can prevent the conduction of heat, thereby reducing the loss or inflow of heat. Its thermal conductivity is low, which effectively slows down the heat transfer. In other embodiments, the heat insulating member 93 can also be expanded perlite, foam plastic, aerogel, etc. This application does not limit this.
[0096] Furthermore, the shell assembly 10 further includes a heat insulation cover 17, which is connected to the middle shell 12 and partially encloses the middle shell 12 to form a hot tank cavity 102. The heat insulation cover 17 is covered on a portion of the outer peripheral wall of the hot tank assembly 20. The heat insulation cover 17 can be made of a heat insulation material, such as urethane foam (PU), polystyrene foam (EPS), etc. These materials have low thermal conductivity and can effectively reduce the transfer of heat through the heat insulation cover 17. The outer surface of the heat insulation cover 17 can also be coated with a waterproof coating, such as waterproof paint or a hydrophobic coating, so that the heat insulation cover 17 can be waterproof and heat-insulating.
[0097] See also Figure 7 and Figure 8In 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 part of the hot tank assembly 20. The tank body 21 is arranged in the hot tank cavity 102 along the up-down direction and has a heating cavity 21a for accommodating liquid to be heated. The heating element 22 is at least partially disposed in the heating cavity 21a to heat the liquid in the heating cavity 21a. During the heating process, water vapor or gas will be generated. Therefore, the tank body 21 also has an exhaust port 215 connected to the heating cavity 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 the faucet 92. The faucet 92 is provided with an air outlet to discharge the gas in the tank body 21 from the air outlet through the exhaust pipe 24. It is used to discharge the gas generated during the heating process, and can effectively discharge the water vapor or other gas generated during the heating process out of the tank, prevent the pressure accumulation in the tank body 21, and improve the safety and stable operation of the hot tank assembly 20.
[0098] The hot tank assembly 20 also includes a detection assembly 23, which includes a mounting bracket 231 and a plurality of sensor units mounted on the mounting bracket 231. The mounting bracket 231 is insulated and connected to the tank body 21 to ensure that the sensor can accurately detect without being affected by the temperature of the tank body 21. The plurality of sensor units include at least two types. The sensor unit is used to detect the liquid in the heating chamber 21a, that is, the probe part of the sensor unit extends into the heating chamber 21a. The detection assembly 23 can be used to detect the state of the liquid in the heating chamber 21a, including but not limited to temperature, liquid level, water quality, etc. In the hot tank assembly 20, a plurality of different sensor units are provided to detect different parameters, such as temperature, pressure, liquid level, water quality, etc. These parameters are crucial to ensure the accuracy and safety of the heating process, and are helpful to diagnose possible faults of the system and take timely measures. The heating process can be controlled more accurately by a plurality of sensor units, overheating or insufficient heating can be avoided, and the heating quality of the water can be ensured. Since a plurality of sensor units need to be installed on the tank body 21, there is a situation where they are installed incorrectly when they are assembled separately.
[0099] In the related art, multiple sensor units are usually installed separately, that is, multiple connecting plates are required to enable the sensor units to be connected to the tank body 21, which results in more parts required and low assembly efficiency. In this embodiment, multiple sensor units are integrated and installed on the mounting bracket 231, and then the mounting bracket 231 is connected to the tank body 21, which has high assembly efficiency and requires fewer parts. The potential unstable factors caused by multiple independent connecting plates are reduced, and the integrated installation reduces the number of sensor units that need to be installed and calibrated separately, thereby simplifying the assembly process and improving production efficiency.
[0100] In this embodiment, at least two types of sensor units are arranged at intervals along the same horizontal direction, so as to reduce signal interference between the sensor units and improve data collection accuracy.
[0101] Specifically, the sensor unit includes at least two of 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 is used to detect the temperature of the liquid in the heating chamber 21a to ensure that the liquid reaches the set heating temperature and prevents overheating or insufficient heating. The water level sensor 232 is used to detect the water level of the liquid in the heating chamber 21a and detect the water level in real time. The water quality sensor 236 is used to detect the water quality to ensure that the provided water quality meets the drinking standard. When the water quality deteriorates, an alarm can be issued in time, and the filter element may need to be replaced or other treatments may be performed. The dissolved oxygen sensor is used to measure the dissolved oxygen content in the water and detect the freshness and quality of the water. The pressure sensor is used to detect the pressure in the heating chamber 21a to prevent the pressure in the tank 21 from being too high, causing equipment damage or safety accidents. Through the coordinated use of the sensor unit, the heat and water purifier 1 can operate more intelligently while providing a safer and more standard use environment.
[0102] like Figure 8 As 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 will send a signal to notify the control panel 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 water outlet of the filtration system 50 to replenish water in the heating chamber 21a, ensuring that the heat and water purifier 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 will send a signal to notify the control panel 80 to control the filtration system 50 to stop replenishing water into the heating chamber 21a, to prevent excessive water inflow, and to avoid excessive water in the heating chamber 21a causing overflow and losses. 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.
[0103] like Figure 8 and Fig. 9As shown, in some embodiments, the tank body 21 includes a tank body 211, a tank top cover 212 connected to the top of the tank body 211, and a tank bottom cover 213 connected to the bottom of the tank body 211. The tank body 211 is cylindrical, and the tank body 211, the tank top cover 212 and the tank bottom cover 213 together constitute a heating chamber 21a, providing good mechanical strength and stability, and ensuring that the tank body 21 is not easily deformed during the heating process. Among them, the mounting bracket 231 can be selectively connected to the tank top cover 212 or the tank bottom cover 213, providing installation flexibility, and the best installation position can be selected according to actual needs and space limitations, which can optimize the equipment layout and save space, especially when the installation space is limited. Different installation positions may be suitable for different application scenarios. For example, in some cases, installing the bracket on the tank top cover 212 may be more convenient for operation and maintenance, while in other cases, installing it on the tank bottom cover 213 may be more appropriate.
[0104] This embodiment is described by taking the connection of the mounting bracket 231 to the tank top cover 212 as a specific application example. The technical solution is also applicable to the connection of the mounting bracket 231 to the tank bottom cover 213. Corresponding adjustments and improvements can be made with reference to this embodiment.
[0105] like Fig. 9 and Fig.10 As shown, in some embodiments, the tank top cover 212 has at least two positioning holes 212a, wherein the mounting bracket 231 includes a main board body 2311 and at least two probe posts 2312, at least two probe posts 2312 are connected to the main board body 2311, and at least two probe posts 2312 are plugged into the at least two positioning holes 212a in a one-to-one correspondence, and the sensor unit is inserted into the probe posts 2312 to ensure that the sensor unit is accurately positioned at the desired position, thereby improving the accuracy and reliability of the installation, and the wire portion of the sensor unit is exposed outside the positioning hole 212a, and the wire portion of the sensor unit is connected to the probe portion in the probe post 2312, and the wire portion can convert the parameters detected by the probe portion (such as temperature, humidity, pressure, etc.) into electrical signals and transmit them to the subsequent processing unit.
[0106] The main board 2311 can be selectively arranged on the side of the tank top cover 212 facing or away from the heating chamber 21a. When the main board 2311 is installed on the side of the tank top cover 212 facing the heating chamber 21a, it is necessary to assemble the mounting bracket 231 and the tank top cover 212 before the tank top cover 212 is spliced to the tank body 211, and then connect the tank top cover 212 and the mounting bracket 231 to the tank body 211. The main board 2311 is located on the side of the tank top cover 212 facing the heating chamber 21a, which can reduce the external space occupied by the main board 2311 and achieve a more compact design.
[0107] When the main board 2311 is installed on the side of the tank top cover 212 away from the heating chamber 21a, the tank top cover 212 can be first spliced to the tank body 211, and then the mounting bracket 231 and the tank top cover 212 can be assembled. Of course, the mounting bracket 231 can also be connected to the tank top cover 212 first and then spliced to the tank body 211 as a module. The main board 2311 is located on the side of the tank top cover 212 away from the heating chamber 21a, which helps to reduce the impact of heat on the main board 2311, and because the main board 2311 is exposed to the outside, it is easier to perform maintenance and overhaul work. This embodiment can select the installation position according to the installation requirements, providing higher flexibility and adaptability. Whether facing the heating chamber 21a or away from the heating chamber 21a, the normal operation and maintenance of the sensor unit can be ensured.
[0108] In other embodiments, the main board 2311 may also be selectively disposed on a side of the tank bottom cover 213 facing toward or away from the heating chamber 21 a, which will not be described in detail herein.
[0109] The specific application example is described below with the main board body 2311 disposed on the side of the tank top cover 212 facing the heating chamber 21a. The technical solution is also applicable to the case where the main board body 2311 is disposed on the side cover of the tank top cover 212 facing away from the heating chamber 21a. Corresponding adjustments and improvements can be made with reference to this embodiment.
[0110] Please continue reading Fig. 9 and Fig.10 In order to achieve a tight connection between the mounting bracket 231 and the tank top cover 212, the hot tank assembly 20 also includes a connecting piece 28. The tank top cover 212 has a connecting hole 212b. The mounting bracket 231 also includes a connecting column 2313. The connecting column 2313 is connected to the main body 2311 and is located on the side facing the heating chamber 21a. It extends in the direction of the heating chamber 21a. The connecting column 2313 is provided with a connecting blind hole 2313a on the side facing the tank top cover 212. The connecting piece 28 connects the connecting hole 212b and the connecting blind hole 2313a, so that the mounting bracket 231 is connected to the tank top cover 212, thereby 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.
[0111] Since the opening direction of the connecting blind hole 2313a is located on the side facing the tank top cover 212, the connecting member 28 is less likely to contact the liquid in the heating chamber 21a, effectively preventing the connecting member 28 from contaminating the heated liquid, and keeping the liquid in the heating chamber 21a clean and pure. It can also prevent the connecting member 28 from being directly exposed to the high temperature environment in the heating chamber 21a, which helps to protect the connecting member 28 from heat and prolong its service life.
[0112] The connection member 28 may be a screw member, that is, the connection blind hole 2313a is a threaded blind hole, and the screw member may be threaded from above to be connected to the tank top cover 212 and the connection column 2313. In other embodiments, the connection member 28 may also be a self-tapping screw. Understandably, before assembly, the tank top cover 212 and the connection column 2313 do not need to be provided with the connection hole 212b and the connection blind hole 2313a, respectively, because the self-tapping screw will form a thread when screwed in, and the thread formed by the self-tapping screw when screwed into the material can fit the material tightly, thereby enhancing the structural integrity of the connection.
[0113] It should be noted that the number of connection 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 in the same radial direction of the tank top cover 212 and the length direction of the mounting bracket 231, and two connection holes 212b can be provided, respectively arranged on the left and right sides of the above-mentioned radial direction, and are centrally symmetrically arranged. The two connection blind holes 2313a and the two connection holes 212b are respectively arranged in position and arranged along the length direction of the mounting bracket 231 to ensure the balance on the tank top cover 212 and reduce the stress concentration caused by the eccentric load. It can be understood that in other embodiments, the connection holes 212b can be provided with 3, 4 or even more, and can also be arranged in a circumferential array, and this application does not limit this.
[0114] Furthermore, the main body 2311, the probe column 2312 and the connecting column 2313 are integrated components, and the integrated design reduces the number of components, simplifies the overall structure, and reduces the complexity of assembly. It also has better overall rigidity, can reduce deformation that may occur during operation, and improve the stability and reliability of the hot tank assembly 20.
[0115] Please continue reading Fig. 9 and Fig.10 In some embodiments, the detection assembly 23 further includes a seal 238, which is disposed between the main body 2311 and the tank top cover 212. The seal 238 is used to seal the gap between the main body 2311 and the tank top cover 212, and the seal 238 has an opening disposed opposite to the positioning hole 212a and the connecting hole 212b. It is understandable that the purpose of providing the seal 238 is to prevent the internal gas from overflowing from the positioning hole 212a and the connecting hole 212b, that is, the seal 238 can improve the sealing of the heating chamber 21a, prevent the liquid in the heating chamber 21a from overflowing, and further reduce heat loss and improve the energy efficiency of the device. It can also prevent external pollutants such as dust and bacteria from entering the interior of the heating chamber 21a, and keep the internal environment clean.
[0116] The seal 238 can be an integrated seal 238 or a split seal 238. The integrated seal 238 can evenly distribute the spring tightening force to different positions, reduce the aging speed and wear of the integrated seal 238, and thus extend the service life. The split seal 238 is arranged in a split manner, and multiple sub-seals 238 are arranged to correspond to at least two positioning holes 212a and at least one connecting hole 212b. The use of the split seal 238 includes multiple sub-seals 238, and any sub-seal 238 can be replaced separately when it is damaged, without replacing the entire seal 238, thereby reducing maintenance costs.
[0117] Furthermore, the seal 238 can be a rubber part, a silicone part, 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 a high temperature environment and withstand long-term use without being easily damaged.
[0118] See also Fig.10 In some embodiments, the hot tank assembly 20 further includes a first water pump 30 and a water outlet pipe 31, and the water inlet end of the first water pump 30 is connected to the heating chamber 21a. In one configuration, the first water pump 30 is installed and fixed on the side of the tank body 21, and specifically, the water outlet 216 is opened on the tank body 211, wherein specifically, the pump housing of the first water pump 30 is directly fixedly connected to the tank body 211 through fasteners, and a sealing ring is provided between the pump housing and the tank body 211. Alternatively, the inlet and the water outlet 216 of the first water pump 30 are connected through a water pipe.
[0119] In another setting form, the first water pump 30 is installed and fixed on the tank bottom cover 213 of the tank body 21, that is, the water outlet 216 is opened on the tank bottom cover 213, wherein specifically, the pump casing of the first water pump 30 is directly fixedly connected to the tank bottom cover 213 through fasteners, and a sealing ring is arranged between the pump casing and the tank bottom cover 213.
[0120] The water outlet of the first water pump 30 is connected to the water outlet pipe 31. The first water pump 30 is used to pump the liquid in the heating chamber 21a to the water outlet pipe 31. Compared with the natural flow, the first water pump 30 can provide a more stable and rapid water flow, improve the efficiency of hot water output, and prevent the hot water from flowing back to the heating chamber 21a. The water 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 users to use.
[0121] It should be noted that the air purifier and heat integrated machine 1 of the present application can also realize the function of users obtaining the set water temperature, that is, the user can also obtain warm water with a temperature between normal temperature water and hot water discharged from the hot tank assembly 20 from the faucet 92. To this end, the air purifier and heat integrated machine 1 of the present application can further include a temperature detector, the sensor unit is at least used to detect the temperature in 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 boost pump 70 to form warm water with a set temperature value at the faucet 92.
[0122] Specifically, after multi-stage filtration (such as the first filter element 51 and the second filter element 52), the filtration system 50 outputs pure water at room temperature that can be directly drunk. The temperature of the water at room temperature is detected by the temperature detector and fed back to the controller. The water at room temperature is usually close to the ambient temperature, such as 20°C. The heating chamber 21a of the hot tank assembly 20 heats the filtered pure water through the heating element 22 and outputs hot water. The temperature of the hot water is detected by the sensor unit and fed back to the controller to ensure that the temperature of the hot water reaches the set value (such as 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 water at room temperature according to the target temperature set by the user, so that the temperature of the mixed water reaches 60°C.
[0123] When the user sets the required water temperature through the control panel of the faucet 92 or the mobile phone APP, the controller will calculate the required flow ratio of hot water and pure water according to this set value. The controller can adjust the flow of hot water by controlling the operating power of the first water pump 30, thereby affecting the water temperature at the faucet 92. The waterway plate 60 is responsible for guiding the flow path of hot water and normal temperature water, and mixing the two and delivering them to the faucet 92. By controlling the operating power of the booster pump 70, the flow of raw water entering the reverse osmosis filter element can be adjusted, thereby affecting the flow of pure water after filtration. By accurately controlling the operating power of the first water pump 30 and the booster pump 70, the appropriate mixing of hot water and pure water can be achieved, thereby outputting warm water of the set temperature value at the faucet 92.
[0124] Please continue reading Fig.10The hot tank assembly 20 also includes a common water level sensor 235, which is used in conjunction with a high water level sensor 233 and a low water level sensor 234. The common water level sensor 235 can form a water level detection loop with the high water level sensor 233 and the low water level sensor 234. Such a 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 verify data with each other to ensure 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 devices to trigger early warnings and execute emergency measures.
[0125] However, since the high water level sensor 233 and the low water level sensor 234 need to form a detection circuit with the common water level sensor 235, these belong to the weak current system. The heating element 22 belongs to the strong current system. If the strong and weak currents are not arranged reasonably, the electromagnetic interference generated by the strong current may affect the normal operation of the weak current system, resulting in inaccurate water level detection. And when the water level detection circuit is close to the heating element 22, there is a risk of being broken down by the strong current, which will cause the water level detection circuit to fail and affect the accuracy and reliability of water level detection. Further, when air blockage occurs at the water inlet end of the first water pump 30, it may cause the resistance between the common water level sensor 235 and the low water level sensor 234 to increase, but since the resistance changes in the air blockage and low water level situations are similar, it may cause misjudgment and fail to accurately distinguish between air blockage and low water level situations.
[0126] To solve the above problems, in this embodiment, the public water level sensor 235 is insulated from the water outlet pipe 31, saving space on the tank top cover 212, and the probe part of the public water level sensor 235 extends into the water outlet pipe 31, which can effectively isolate the electromagnetic interference generated by the strong electric system (such as the heating element 22), ensure the signal stability of the weak electric system (water level detection circuit), and improve the accuracy of water level detection. In addition, the probe part of the public water level sensor 235 extends into the water outlet pipe 31, away from the heating element 22, reducing the risk of electrical breakdown caused by a fault in the strong electric system, and ensuring the long-term stable operation of the water level detection circuit.
[0127] Further, when the common water level sensor 235 detects an increase in resistance, the control system will receive this signal and determine that air blockage may have occurred. After air blockage occurs, the heat and air purifier 1 will automatically stop the operation of the first pump 30, allowing the bubbles in the air blockage to float away naturally, thereby clearing the blockage. After shutdown, the control system will recheck the resistance value between the common water level sensor 235 and the low water level sensor 234. If the recheck result shows that the resistance value remains high, this indicates that the tank body 21 has reached a low water level, and the system is shut down normally at this time to avoid the first pump 30 from idling. If the resistance value returns to a low resistance value, the control system will determine that it is an air blockage situation, and the first pump 30 will continue to power on and discharge water, and resume normal operation. Through this setting, the control system can effectively distinguish between air blockage and actual low water level situations, avoiding misjudgment caused by air blockage and potential damage to the first pump 30. The design of the common water level sensor 235 located in the outlet pipe 31 enables it to directly detect the working state of the first pump 30, thereby improving the accuracy of water level detection. This coordinated use method enhances the adaptive capability and fault diagnosis capability of the hot tank assembly 20 , and improves the overall operating efficiency and reliability of the hot tank assembly 20 .
[0128] The heating element 22 is usually located on one side of the heating chamber 21a near the tank bottom cover 213. Due to the heating effect of the heating element 22, the water in the tank body 21 is prone to stratification, and the cold water at the bottom is not heated enough, that is, the water temperature at the bottom is low, while the water temperature at the top is high. When the first water pump 30 is set at the tank bottom cover 213 or on a side close to the tank bottom cover 213, since the water close to the bottom is directly pumped, this will cause the temperature of the first cup of water to be lower than expected, affecting the consistency of the water temperature.
[0129] like Fig.11 As shown, in some embodiments, along the height direction of the tank body 21, part of the water outlet pipe 31 is arranged in the heating chamber 21a and extends out of the tank top cover 212, that is, part of the water outlet pipe 31 is connected to the outside of the tank body 21, and the water outlet pipe 31 can be arranged in the heating chamber 21a by bending, so that the insufficiently heated water in the water outlet pipe 31 has the opportunity to exchange heat with the hot water in the heating chamber 21a, thereby increasing the water temperature. The heat in the heating chamber 21a can be more effectively utilized, energy waste can be reduced, energy efficiency can be improved, and heat loss of hot water during transportation can be reduced, the water temperature can be maintained, and the problem of low temperature of the first cup of water can be weakened.
[0130] 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 heated again during the next heating. Therefore, when the user takes water at a long interval or takes water for the first time, the residual cold water will not be directly discharged but heated to improve the consistency of the water temperature.
[0131] If the exhaust pipe 24 and the water outlet pipe 31 intersect and are connected, when taking hot water, the faucet 92 may spray steam. This phenomenon is usually caused by the flow of hot water driving the water vapor in the exhaust pipe 24 to flow out together, resulting in the user not only having hot water but also steam spraying out when using the faucet 92, affecting the user experience and possibly causing safety hazards.
[0132] To solve the above problems, Fig.10 As shown, in some embodiments, the exhaust pipe 24 is connected to a condenser 29, which can liquefy the water vapor in the exhaust pipe 24. The condenser 29 is vertically arranged above the tank top cover 212. When the water vapor is liquefied, it can flow into the exhaust pipe 24 along the wall of the condenser 29 and then enter the heating chamber 21a, thereby reducing the discharge of water vapor, that is, reducing the problem of steam spraying from the faucet 92 when the user takes hot water. The liquefied water in the exhaust pipe 24 flows back into the heating chamber 21a, which is equivalent to increasing the amount of water in the heating chamber 21a, thereby reducing the waste of water resources.
[0133] It should be noted that the inner diameter of the condenser 29 is greater than 8 mm, which is greater than the inner diameter of the exhaust pipe 24. The larger inner diameter of the condenser 29 can increase the contact area of the flowing gas, enhance the convective heat transfer, improve the condensation heat exchange performance, increase the effect of liquefaction of the gas flowing through the condenser 29, and reduce the gas spray phenomenon of the faucet 92.
[0134] Please continue reading Fig.10 In one configuration, the condenser 29 is connected to the exhaust pipe 24 in sequence, and the condenser 29 is located above the exhaust pipe 24 so that the gas in the exhaust pipe 24 will be condensed by the condenser 29 before passing to the faucet 92.
[0135] like Fig.14 As shown, in another configuration scheme, the condenser 29 is covered on the outer peripheral wall of the exhaust pipe 24, that is, the exhaust pipe 24 is inserted into the condenser 29, and part of the outer peripheral wall of the condenser 29 is spaced apart from the exhaust pipe 24. The condenser 29 is connected to the water supply pipe 25, so that the pure water in the water supply pipe 25 can first flow through between the condenser 29 and the exhaust pipe 24, and then flow into the heating chamber 21a. By using pure water to exchange heat with the high-temperature water vapor in the exhaust pipe 24, the water vapor can be effectively condensed, and the pure water is preheated when flowing through the condenser 29. The preheated water enters the heating chamber 21a, which can reduce the time required for heating to the set temperature, further improve the thermal efficiency, and reduce the waste of heat.
[0136] It should be noted that the water supply pipe 25 is inserted into the tank top cover 212 and extends more than 3 mm toward the heating chamber 21a. Extending the water supply pipe 25 can prevent water from flowing back because the extended part will form a certain height difference in the water supply pipe 25, making it impossible for water to flow back through the siphon effect.
[0137] like Fig.15 and Fig.16 As shown, in another arrangement, the portion of the water outlet pipe 31 extending from the tank top cover 212 is passed through the exhaust pipe 24 and communicated with the exhaust pipe 24, and the water outlet pipe 31 and the exhaust pipe 24 are spaced apart to form an outlet passage, and the hot tank assembly 20 further includes a three-way pipe 26, the three-way pipe 26 having 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 the water outlet pipe 31 passing through the exhaust pipe 24 and communicated with the water outlet pipe 31, and the third interface 263 is connected to the air outlet channel, and the gas in the heating chamber 21a is discharged from the third interface 263, and the three-way pipe 26 is a three-way elastic tube, which can be fastened and ringed on one end of the water outlet pipe 31 and one end of the exhaust pipe 24 at the same time to prevent the gas in the heating chamber 21a from entering the hot water outlet channel from the gap between the water outlet pipe 31 and the second interface 262. The provision of the three-way pipe 26 can avoid welding when the water outlet pipe 31 is passed through the tank top cover 212, making maintenance and replacement easier without the need for complicated welding operations, thereby reducing the difficulty and cost of maintenance.
[0138] like Fig.11 As shown, in order to reduce the occurrence of low temperature of the first cup of water, in some embodiments, the tank body 211 has a water outlet 216 connected to the water inlet end of the first water pump 30 and the heating chamber 21a, wherein along the height direction of the tank body 21, the position of the water outlet 216 is higher than the bottom end of the heating element 22. During the heating process, water may be stratified due to density differences, with hotter water rising and colder water sinking. If the water outlet 216 is located at the bottom end of the heating element 22, then a cold water layer that is not fully heated may be extracted. Setting the water outlet 216 at a position higher than the bottom end of the heating element 22 helps to extract water from the middle and upper layers with better mixing, that is, the higher position of the water outlet 216 can ensure that when taking water, the hotter water in the heating chamber 21a is taken out first, thereby reducing the problem of low temperature of the first cup of water.
[0139] In some embodiments, Figure 8As shown, the heating element 22 includes a heating tube 222 and two wiring terminals 221, the two wiring terminals 221 are respectively connected to the two ends of the heating tube 222, and the wiring terminals 221 extend outside the tank body 21 to connect to an external power source, so that the connection and disconnection of the heating tube 222 are more convenient. The plane where the bottom end of the heating tube 222 is located is basically parallel to the tank bottom cover 213, so that the bottom end of the heating tube 222 can be arranged as close to the tank bottom cover 213 as possible, and it will not be as in the related art that the heating tube 222 is spirally tilted and spiraled in the heating chamber 21a, resulting in a large distance between the bottom end of the heating tube 222 and the tank bottom cover 213. The heating tube 222 in this embodiment can be arranged 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, making the water temperature in the entire tank body 21 more uniform, and the temperature of the first cup of water will be improved, avoiding the problem of low water temperature of the first cup of water caused by the direct outflow of cold water from the bottom.
[0140] like Figure 1 , Fig.12 and Fig.13 As shown, in one embodiment, the hot tank assembly 20 also includes a reflux pipe 291, which is connected to the tank top cover 212 and communicated with the heating chamber 21a. The reflux pipe 291 also intersects and communicates with the water outlet pipe 31. The first water pump 30 can pump out the liquid in the heating chamber 21a near the tank bottom cover 213, and a reversing valve is provided between the reflux pipe 291 and the water outlet pipe 31. The water temperature of the liquid just pumped out may not reach the target temperature. The water outlet end of the first water pump 30 is connected to the reflux pipe 291 through the reversing valve, and the liquid flows back to the heating chamber 21a for reheating. When the preset time is reached, the water outlet end of the first water pump 30 can be connected to the water outlet pipe 31 through the reversing valve, and the hotter liquid is delivered to the faucet 92 for user reference.
[0141] Understandably, in another embodiment, the reversing valve may not be provided, that is, the return pipe 291 and the water outlet pipe 31 are separate water paths, and the hot tank assembly 20 is provided with a second water pump 292, the second water pump 292 is connected to the tank bottom cover 213, and the water inlet end of the second water pump 292 is communicated with the heating chamber 21a, so as 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 water outlet end of the second water pump 292, and the other end is connected to the tank top cover. 212, so that the liquid can flow back to the heating chamber 21a through the reflux pipe 291 and be reheated. The liquid in the heating chamber 21a near the tank bottom cover 213 can be pumped out by the second water pump 292, and then flow back to the heating chamber 21a through the reflux pipe 291 and be reheated. This helps to improve the water temperature stratification phenomenon in the tank and make the water temperature more uniform, that is, reduce the direct outflow of cold water at the bottom, and send the colder water back to the heating chamber 21a through the reflux pipe 291 for heating, thereby increasing the temperature of the first cup of water.
