DETAILED DESCRIPTION

[0032] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0033] Please refer to Figures 1-4 The present embodiment provides a water purification and heating all-in-one machine 1, which comprises a shell assembly 10, a faucet 1A, a hot tank assembly 20 and a filtering system 50.

[0034] The shell assembly 10 has an inner cavity 10A, and the hot tank assembly 20 and the filtering system 50 are installed in the inner cavity 10A, so as to protect the hot tank assembly 20 and the filtering system 50 by the shell assembly 10, and reduce the probability of damage of the hot tank assembly 20 and the filtering system 50. It can be understood that the material of the shell assembly 10 can be at least one of metal and plastic. For example, the material of the shell assembly 10 can be metal, so that the shell assembly 10 has high structural strength as a whole, so as to reduce the probability of damage of the shell assembly 10, and further reduce the probability of damage of the hot tank assembly 20 and the filtering system 50, so that the net heat all-in-one machine 1 can have a long service life. The material of the shell assembly 10 can also be plastic, which can reduce the weight and material cost while ensuring the structural strength.

[0035] The faucet 1A is connected with the shell assembly 10 and communicates with the hot tank assembly 20 and the filtering system 50. When the faucet 1A is opened, the hot water in the hot tank assembly 20 or the normal temperature water in the filtering system 50 can flow out through the faucet 1A to provide hot water or normal temperature water for the user. It can be understood that the net heat all-in-one machine 1 can have two faucets 1A, one of which communicates with the hot tank assembly 20 and the other of which communicates with the filtering system 50, so as to provide hot water and normal temperature water for the user separately. In other embodiments, the faucet 1A can also communicate with the hot tank assembly 20 and the filtering system 50 respectively, and the faucet 1A can be controlled to flow out hot water or normal temperature water by a switch.

[0036] It can be understood that the faucet 1A can also be a smart faucet 1A. When the controller detects a normal temperature water taking signal or a hot tank assembly 20 water replenishing signal at the smart faucet 1A, the controller can control the filtering system 50 to start water making, so as to ensure that the user can take normal temperature water and hot water from the smart faucet 1A in time, reduce the waiting time of the user, and improve the use experience of the user.

[0037] The hot tank assembly 20 communicates with the faucet 1A and communicates with the filtering system 50, so as to heat the normal temperature water filtered by the filtering system 50 and provide hot water for the user when the faucet 1A is opened.

[0038] The filtering system 50 can be connected with a water pipe, and the filtering system 50 comprises a filter element, a booster pump 55, a water inlet electromagnetic valve, and a purified water pipe, the outlet of the filter element is connected with the purified water pipe, and the purified water pipe is further connected with the faucet 1A. The booster pump 55 and the electromagnetic valve are electrically connected with the controller, and the filtering system 50 is controlled to start water production when the controller detects a signal of taking normal-temperature water at the faucet 1A or a signal of water replenishment of the hot tank assembly 20, and the filtering system 50 is controlled to stop water production and enter a standby state when the two signals disappear. The normal-temperature water at the water outlet of the filtering system 50 can enter the hot tank assembly 20 or directly flow out through the faucet 1A. Of course, when the user needs to take normal-temperature water, the water replenishment valve 251 can also be opened, that is, the filtering system 50 can also simultaneously meet the requirements of producing normal-temperature water and replenishing water for the hot tank assembly 20.

[0039] Please refer to Figures 1-4 It can be understood that the faucet 1A can also be installed near the operation panel and be communicated with the hot tank assembly 20 and the filtering system 50 through pipelines, so that the user can control the water outlet of the faucet 1A through the operation panel, thereby facilitating the user to take hot water and normal-temperature water from the faucet 1A.

[0040] For example, the filtering system 50 can comprise a plurality of filter elements, which can be independently arranged or integrated into a composite filter element.

[0041] Please refer to Figure 3 Specifically, the filtering system 50 can comprise a water inlet valve 51, a first filter element 52, a second filter element 53, a booster pump 55, and a one-way valve 56, the water inlet end of the water inlet valve 51 is communicated with a raw water inlet, the water outlet end of the water inlet valve 51 is communicated with the water inlet end of the first filter element 52, the water outlet end of the first filter element 52 is communicated with the water inlet end of the booster pump 55, the water outlet end of the booster pump 55 is communicated with the water inlet end of the second filter element 53, the water outlet end of the second filter element 53 is communicated with the water inlet end of the one-way valve 56, and the water outlet end of the one-way valve 56 is communicated with the water outlet end of the filtering system 50.

[0042] The first filter element 52 is used to realize the preliminary filtration of raw water, and can filter out large-particle substances such as silt, rust, insect eggs, and red worms in the raw water. The raw water can be tap water, well water, etc., and the first filter element 52 can be a PP cotton filter element (polypropylene melt-blown filter element), a carbon rod filter element, a composite filter element, etc.

[0043] The second filter element 53 has a reverse osmosis membrane, which can be an artificial semi-permeable membrane. The reverse osmosis membrane has very small membrane pore size, and can effectively remove dissolved salts, colloids, microorganisms, organic matter and other impurities in water. A pure water pipe is connected between the second filter element 53 and the faucet 1, so that the user can obtain the water filtered by the second filter element 53 through the faucet 1A. The water filtered by the second filter element 53 can be pure water, i.e. normal temperature water. Of course, a waste water pipe 531 is also connected to the second filter element 53, and a waste water valve 532 can be arranged on the waste water pipe 531 to control the discharge of waste water.

[0044] In other embodiments, the filtration system 50 can further include a third filter element, the water inlet end of the third filter element being in communication with the water outlet end of the second filter element, and the water outlet end of the third filter element being in communication with the water outlet end of the filtration system 50.

[0045] The third filter element is used to adsorb odor and residual chlorine, and can be used to improve the taste of normal temperature water. The third filter element can be an activated carbon filter element.

[0046] It can be understood that, in order to facilitate the water outlet end of the filtration system 50 to supply water to the hot tank assembly 20 and directly provide normal temperature water to the faucet 1A, the hot tank assembly 20 can include a water supply pipe 25 and a water supply valve 251 arranged on the water supply pipe 25. When the hot tank assembly 20 needs to be supplied with water, the water supply valve 251 is opened, and the normal temperature water at the water outlet end of the filtration system 50 can enter the hot tank assembly 20. When the user needs to take normal temperature water, the water supply valve 251 is closed, and the normal temperature water at the water outlet end of the filtration system 50 can flow out through the faucet 1A.

[0047] Please refer to Figures 1-4 It can be understood that the net hot all-in-one machine 1 can further include a pipeline machine 57, and the normal temperature water can enter the pipeline machine 57 after passing through the one-way valve 56 to supply water to the pipeline machine 57.

[0048] Due to the large number of components of the filtration system 50 and the hot tank assembly 20 and the lack of systematicness in the installation sequence, problems such as limited operation space, inaccurate positioning of components, and difficulty in immediate debugging and testing often occur during assembly, resulting in low assembly efficiency and low product qualification rate. To solve the above problems, the shell assembly 10 of the present application includes a middle shell 11 and an outer shell 12, the outer shell 12 is arranged around the outer periphery of the middle shell 11, a waterway board 60, a filtration system 50 and a hot tank assembly 20 are all connected to the middle shell 11.

[0049] Based on the above embodiments, by adopting the shell assembly 10 including the middle shell 11 and the outer shell 12, the inner cavity 10A is arranged in the middle shell 11, and the waterway plate 60, the filter system 50, and the heat tank assembly 20 are all connected to the middle shell 11, which greatly optimizes the assembly process and performance of the water heating and purifying integrated machine 1. In terms of assembly, the middle shell 11 provides a stable and relatively independent assembly platform for each component, solving the assembly problem caused by limited operation space, and workers can more conveniently and accurately position and install the filter system 50 and the heat tank assembly 20, improving assembly efficiency and accuracy. Compared with direct assembly in the outer shell 12, operation on the middle shell 11 can reduce the inconvenience caused by the shape and space limitations of the outer shell 12.

[0050] At the same time, this connection method facilitates immediate debugging and detection of each component during assembly. After the filter system 50 and the heat tank assembly 20 are installed on the middle shell 11, preliminary debugging and detection of some functional modules on the middle shell 11 can be performed, potential problems can be found and solved in a timely manner, and the workload of rework and maintenance is reduced, effectively improving product qualification rate and reducing production cost. In contrast, if detection is performed after the outer shell 12 is closed, once a problem is found, the outer shell 12 needs to be disassembled for maintenance, which increases the difficulty and cost of maintenance. From the performance point of view, the stable assembly structure ensures the connection reliability between the waterway plate 60, the filter system 50, and the heat tank assembly 20, ensures the stable transmission of water flow and the effective utilization of heat, improves the overall operation stability and reliability of the equipment, and thus provides users with a more stable and efficient water heating and purifying integrated functional experience.

[0051] Please refer to Figures 1-4 It should be noted that the outer shell 12 and the middle shell 11 are fixed by screws or buckles, etc., to ensure close combination and maintain the stability and protection of the overall structure, and to protect the internal components from external interference.

[0052] Please refer to Figures 1-4Further, the middle shell 11 has a mounting cavity 11A and a mounting opening 11B in communication with the mounting cavity 11A, and the mounting opening 11B is used for the filter element of the filter system 50 to pass through and be mounted in the mounting cavity 11A. It can be understood that when the filter element passes through the mounting opening 11B and is fixed in the mounting cavity 11A, the filter element and the middle shell 11 form a tightly integrated whole structure. In this way, it can effectively avoid the displacement, loosening or even damage of the filter element due to water flow impact, equipment vibration or other external factors, thereby ensuring the stability and reliability of the filter system 50, so that the filtration process can be continuously and efficiently carried out. From the perspective of long-term use, the stable filter element mounting method reduces the risk of filter medium wear and leakage caused by frequent shaking or displacement of the filter element, prolongs the service life of the filter element, and reduces the frequency and cost of replacing the filter element for the user. At the same time, the stable filtration process also ensures the stability of the water quality, provides a solid foundation for the stable operation of the waterway board 60 and the entire water and heat integrated machine 1, reduces the potential damage to other parts of the equipment caused by water quality fluctuations, reduces the overall maintenance rate and maintenance cost of the water and heat integrated machine 1, and improves the durability and performance stability of the water and heat integrated machine 1.

[0053] Please refer to Figures 1-4 It should be noted that when the filter system 50 includes the first filter element 52 and the second filter element 53, two mounting cavities 11A are correspondingly provided on the middle shell 11 to further optimize the installation and management of the filter elements. This design enables filter elements with different functions to be installed and worked in their respective independent and adapted spaces, avoiding possible mutual interference and influence between different filter elements, ensuring that each filter element can fully exert its due filtering efficiency, and improving the filtering precision and efficiency of the entire filter system 50.

[0054] Please refer to Figure 1 , Figure 5 and Figure 6 In an embodiment, the hot tank assembly 20 includes a tank body 21, a heating element 22, and a water pumping pump 30.

[0055] The tank body 21 has a heating cavity 21A, a water replenishing port 214, and a water pumping port 216, both of which are in communication with the heating cavity 21A. The water replenishing port 214 is in communication with the water replenishing pipe 25, and the water replenishing port 214 is in communication with the water replenishing pipe 25, so that when the water replenishing valve 251 is opened, the normal temperature water at the outlet of the filter system 50 can enter the heating cavity 21A through the water replenishing pipe 25 and the water replenishing port 214.

[0056] The heating element 22 is connected to the tank 21 and is used to heat the water in the heating chamber 21A. Exemplarily, the heating element 22 can be disposed inside the tank 21 so that it can directly heat the water in the heating chamber 21A. Exemplarily, the heating element 22 can be a heating pipe. Specifically, the heating pipe can be connected to the tank 21 and extend into the heating chamber 21A. In other embodiments, the heating element 22 can also be disposed outside the tank 21 to heat the tank 21, thereby heating the water in the heating chamber 21A through the heating tank 21. In this application embodiment, there are no specific limitations on the placement position of the heating element 22 on the tank 21 or the specific form of the heating element 22. It is understood that the tank 21 can have a length direction X, and the heating element 22 extends along the length direction X of the tank 21 to ensure uniform heating of the water in the heating chamber 21A.

[0057] The inlet of the water pump 30 is connected to the water outlet 216 of the tank 21, and the outlet of the water pump 30 is connected to the faucet 1A. When the water pump 30 is working and the faucet 1A is open, the water pump 30 can extract the hot water in the heating chamber 21A and pump it to the faucet 1A so that the user can take hot water from the faucet 1A.

[0058] Furthermore, the integrated water purifier and heater 1 of this application can also enable users to obtain a set water temperature. That is, users can also obtain warm water with a temperature between room temperature water and the hot water discharged from the heating tank assembly 20 from the faucet 1A. To this end, the integrated water purifier and heater 1 of this application can further include a first temperature sensor and a second temperature sensor. The first temperature sensor is connected to the tank 21 and is located inside the heating chamber 21A to detect the temperature of the hot water inside the heating chamber 21A. The second temperature sensor is located inside the purified water pipe to detect the room temperature water temperature in the purified water pipe. Both the first and second temperature sensors are connected to a controller. The controller can receive the detection values ​​from the first and second temperature sensors and control the operating power of the water pump 30 and the booster pump 55 to generate warm water at the set temperature value at the faucet 1A. It is understood that the first temperature sensor can also be located in the outlet pipe of the tank 21 to detect the hot water temperature in the outlet pipe of the tank 21.

[0059] It is understandable that the control panel may be equipped with a warm water control device, which may include at least one of buttons, knobs, touch screens, etc. Users can operate the warm water control device to select the desired warm water temperature, so that the faucet 1A can discharge warm water of the selected temperature to meet the user's needs.

[0060] In this embodiment of the application, the specific method steps are explained using 45°C and 55°C warm water as examples.

[0061] When the user selects the temperature of the warm water through the warm water control device, the controller obtains the temperature selection signal of the warm water; if the temperature selection signal is a 45℃ warm water signal, the controller controls the booster pump 55 to adjust the duty ratio to 85%, the controller obtains the current normal water temperature through the first temperature sensor and obtains the current hot water temperature through the second temperature sensor, and calculates the first output duty ratio of the water pump 30 according to the first preset formula, and the controller adjusts the output duty ratio of the water pump 30 according to the first output duty ratio value, at this time, the water outlet of the faucet 1A can flow out 45℃ warm water; when the controller detects that the water level of the tank body 21 drops to a low water level, or the controller receives a closing signal of the faucet 1A, the controller controls the water outlet of the faucet 1A to stop water.

[0062] If the temperature selection signal is not a 45℃ warm water signal, it indicates that the user selects 55℃ warm water, the controller controls the booster pump 55 to adjust the duty ratio to 75%, the controller obtains the current normal water temperature through the first temperature sensor and obtains the current hot water temperature through the second temperature sensor, and calculates the second output duty ratio of the water pump 30 according to the second preset formula, and the controller adjusts the output duty ratio of the water pump 30 according to the second output duty ratio value, at this time, the water outlet of the faucet 1A can flow out 55℃ warm water; when the controller detects that the water level of the tank body 21 drops to a low water level, or the controller receives a closing signal of the faucet 1A, the controller controls the water outlet of the faucet 1A to stop water.

[0063] It can be understood that in other embodiments, the operation panel can also provide other warm water temperature selections, such as 35℃, 50℃ and 60℃, etc., which are not specifically limited in the embodiments of the present application.

[0064] Please refer to Figure 1 , Figure 5 and Figure 6 , in order to facilitate the detection of the water level height in the heating cavity 21A, the hot tank assembly 20 further comprises a high water level probe 233, a low water level probe 234 and a common water level probe 235. When the high water level probe 233 and the common water level probe 235 are conducted through the water in the heating cavity 21A, the controller can receive a high water level signal, so as to determine that the water in the heating cavity 21A is in a high water level state. When the high water level probe 233 and the common water level probe 235 are not conducted through the water in the heating cavity 21A, and the low water level probe 234 and the common water level probe 235 are conducted through the water in the heating cavity 21A, the controller can receive an intermediate water level signal, so as to determine that the water in the heating cavity 21A is in an intermediate water level. When the low water level probe 234 and the common water level probe 235 are not conducted through the water in the heating cavity 21A, the controller can receive a low water level signal, so as to determine that the water in the heating cavity 21A is in a low water level.

[0065] It can be understood that in other embodiments, the liquid level in the heating cavity 21A can also be detected by a floating ball. Of course, the liquid level in the heating cavity 21A can also be detected by a Hall sensor. In the present application, no more details are given.

[0066] In the related art, the high water level probe 233, the low water level probe 234 and the common water level probe 235 are all arranged on the tank body 21 for easy installation, but since the heating element 22 is also connected with the tank body 21, the working voltage of the heating element 22 is much higher than that of the high water level probe 233, the low water level probe 234 and the common water level probe 235, and the common water level probe 235 is also connected with the ground end of the tank body 21, which can cause the common water level probe 235 to be easily broken down by the working voltage of the heating element 22, resulting in damage to the common water level probe 235 and affecting the detection accuracy of the water level in the heating cavity 21A and the service life of the water heating all-in-one machine 1.

[0067] Please refer to Figure 1 , Figure 5 and Figure 6 In the present application, the water pump 30 includes a pump body 30A and a water outlet pipe 31, the inlet of the pump body 30A is communicated with the water suction port 216, and the water outlet pipe 31 is communicated with the outlet of the pump body 30A; the common water level probe 235 is connected with the water outlet pipe 31, and the common water level probe 235 includes a probe 2352 which is arranged in insulation between the tank body 21 and the probe 2352 and extends into the water outlet pipe 31, so that the probe 2352 can be conducted through the water outlet pipe 31, the pump body 30A and the water in the heating cavity 21A and the high water level probe 233 and the low water level probe 234, thereby being able to detect the water level in the heating cavity 21A. And since the common water level probe 235 is arranged on the water outlet pipe 31 and the probe 2352 is arranged in insulation between the tank body 21 and the probe 2352, the probability of damage to the common water level probe 235 can be reduced, so that the common water level probe 235 can have a longer service life, so that the water heating all-in-one machine 1 can have a longer service life, so as to ensure the accuracy of the water level in the heating cavity 21A detected by the high water level probe 233, the low water level probe 234 and the common water level probe 235.

[0068] And, when the pump body 30A is air blocked, bubbles exist in the pump body 30A and the water outlet pipe 31, and since the common water level probe 235 is arranged on the water outlet pipe 31, the existence of the bubbles causes abnormal changes in the resistance between the common water level probe 235 and the low water level probe 234 and the high water level probe 233, so that the water level data obtained by the controller is abnormally changed, so that the controller can determine that the pump body 30A is air blocked according to the abnormal changes, so that the controller can control the driving member to stop working or reduce the working power, so as to reduce the probability of the driving member being burned out by idling, and thus the water pump 30 can have a longer service life, so that the water heating all-in-one machine 1 can have a longer service life.

[0069] Embodiment one: please refer to Figure 1 , Figure 5 and Figure 6 In an embodiment, the pump body 30A comprises an insulating pump shell 30A1 and a driving member (not shown in the figure) arranged in the insulating pump shell 30A1, the insulating pump shell 30A1 is connected with the tank body 21, the water outlet pipe 31 comprises at least one of a metal water outlet pipe 311 and an insulating water outlet pipe 312, and the common water level probe 235 is connected with at least one of the metal water outlet pipe 311 and the insulating water outlet pipe 312. Since the water outlet pipe 31 is connected with the tank body 21 through the insulating pump shell 30A1, the common water level probe 235 is insulated from the tank body 21, and thus the common water level probe 235 is insulated from the heating member 22, so as to reduce the probability of the common water level probe 235 being damaged.

[0070] It can be understood that when the common water level probe 235 is on the water outlet pipe 31, since the common water level probe 235 needs to be electrically connected with the high water level probe 233 and the low water level probe 234 through the water in the water outlet pipe 31, the insulating pump shell 30A1 and the heating cavity 21A, the water between the inlet and the outlet of the pump body 30A needs to be kept in a communicating state. In the embodiment of the present application, the pump body 30A is a water pump without forward and reverse check function, for example, a vane pump, and the driving member is a vane arranged in the pump shell.

[0071] It can be understood that in order to ensure that the common water level probe 235 can form a detection loop with the high water level probe 233 and the low water level probe 234 through the water in the tank body 21, the probe 2352 of the common water level probe 235 should be lower than the end height of the low water level probe 234, so as to ensure that the common water level probe 235 can cooperate with the low water level probe 234 to detect the low water level state of the heating cavity 21A.

[0072] It can be understood that the insulation pump shell 30A1 is a pump shell made of an insulating material, which can be but is not limited to polyvinyl chloride (PVC), polyethylene (PE), epoxy resin (EP), fiber reinforced plastic (FRP), glass fiber, and silicone rubber.

The probe 2352 is insulated from the heating member 22, thereby reducing the probability of damage to the common water level probe 235.

[0075] It can be understood that when the common water level probe 235 includes the insulating cover shell 2351, the pump body 30A can also include the insulating pump shell 30A1, and the water outlet pipe 31 can also include the insulating water outlet pipe 312, which will not be described in detail here.

[0076] Please refer to Figure 1 , Figure 5 and Figure 6In still another specific embodiment, the pump body 30A comprises a metal pump shell 30A2 connected with the tank body 21, and a driving member arranged in the metal pump shell 30A2, the water outlet pipe 31 comprises a metal water outlet pipe 311, and the hot tank assembly 20 further comprises a first insulating mounting structure 28 connected with the metal water outlet pipe 311, and the common water level probe 235 is connected with the first insulating mounting structure 28, so that the common water level probe 235 is also insulated from the tank body 21, and the probe 2352 is insulated from the heating element 22, so as to reduce the probability of damage of the common water level probe 235.

[0079] It can be understood that the hot tank assembly 20 can further comprise a mounting bracket 29 (please refer to Figure 5 ), which is connected with the tank body 21 and the common water level probe 235. When the mounting bracket 29 is a metal bracket, the metal bracket is connected with the insulating covering shell 2351, so that the probe 2352 is insulated from the tank body 21. The mounting bracket 29 can also be an insulating bracket, in which case a suitable form of the common water level probe 235 can be selected according to the pump shell and the water outlet pipe 31 to ensure that the probe 2352 is insulated from the tank body 21, which will not be described in detail here.

[0081] It can be understood that the height of the end of the metal segment 2353 close to the tank body 21 is lower than the height of the end of the low water level probe 234, so as to ensure that the common water level probe 235 can cooperate with the low water level probe 234 to detect the low water level state of the heating cavity 21A.

[0082] Please refer to Figure 9 and Figure 10 In a specific embodiment, the pump body 30A comprises an insulated pump housing 30A1 connected to the tank body 21, the water outlet pipe 31 comprises at least a metal water outlet pipe 311 connected to the insulated pump housing 30A1, and the wire 2354 is connected to the metal water outlet pipe 311; the metal water outlet pipe 311 is the metal segment 2353, so that the metal water outlet pipe 311 and the wire 2354 form the common water level probe 235, and the common water level probe 235 is insulated from the tank body 21 through the insulated pump housing 30A1, so as to reduce the probability of damage to the common water level probe 235.

[0083] Please refer to Figure 1 and Figure 9 In another specific embodiment, the pump body 30A comprises a metal pump housing 30A2 connected to the tank body 21, the water outlet pipe 31 comprises an insulated water outlet pipe 312 and a metal water outlet pipe 311, the insulated water outlet pipe 312 is connected to the metal pump housing 30A2, the metal water outlet pipe 311 is in communication with the insulated water outlet pipe 312, and the wire 2354 is connected to the metal water outlet pipe 311; the metal water outlet pipe 311 is the metal segment 2353, so that the metal water outlet pipe 311 and the wire 2354 form the common water level probe 235, and the common water level probe 235 is insulated from the tank body 21 through the insulated water outlet pipe 312, so as to reduce the probability of damage to the common water level probe 235.

[0084] Please refer to Figure 10 , Figure 1 and Figure 9 In one embodiment, in order to improve the temperature of the first cup of water taken by the user, the tank body 21 comprises a tank body 211, a tank top cover 212 and a tank bottom cover 213, the tank top cover 212 and the tank bottom cover 213 are connected to the tank body 211 to form the heating cavity 21A, and the water suction port 216 can be arranged on the tank body 211 (please refer to Figure 10), and can also make the water extraction opening 216 closer to the heating element 22, so that the temperature of the water extracted by the pump body 30A is higher, and thus the temperature of the first cup of water taken by the user is higher.

[0085] It can be understood that the specific form of the connection between the inlet of the pump body 30A and the tank body 211 can be at least one of screwing, clamping, and welding. In other embodiments, the inlet of the pump body 30A can also be connected to the tank body 211 through a pipe and communicate with the water extraction opening 216. In the embodiments of the present application, the form of the connection between the inlet of the pump body 30A and the tank body 211 is not limited.

[0086] It can be understood that the water extraction opening 216 can also be protruded on the tank bottom cover 213, so that the water extraction opening 216 is closer to the heating element 22, so that the temperature of the water extracted by the pump body 30A is higher, and thus the temperature of the first cup of water taken by the user is higher, and the user's experience of taking hot water is improved. At this time, the pump body 30A is directly bolted to the tank bottom cover 213, so that the inlet of the pump body 30A communicates with the water extraction opening 216.

[0087] Please refer to Figure 1 , Figure 9 and Figure 10 . For example, when the height difference between the center of the water extraction opening 216 and the tank bottom cover 213 is H1, and H1 satisfies 5mm≤H1≤10mm, the water extraction opening 216 can be closer to the heating element 22, so that the temperature of the water extracted by the pump body 30A is higher, and thus the temperature of the first cup of water taken by the user is higher. Moreover, the user can take as much hot water in the heating cavity 21A as possible, and the utilization rate of the hot water in the heating cavity 21A is improved.

[0088] If H1<5mm, the water extraction opening 216 is far away from the heating element 22, the temperature of the water extracted by the pump body 30A is lower, and the temperature of the first cup of water taken by the user is lower.

[0089] If H1>10mm, the water extraction opening 216 is higher, and when the user cannot take hot water from the faucet 1A, there is still a lot of hot water in the heating cavity 21A, which leads to a low utilization rate of the hot water in the heating cavity 21A, and resource waste is caused.

[0096] Specifically, the second insulation mounting structure can comprise two second insulation sealing members (not shown in the figure), which are respectively connected with the tank bottom cover 213 and the tank top cover 212, and are respectively arranged at the first through hole 213A and the second through hole 212A, and each second insulation sealing member has a second connecting hole 281A1, and the second metal pipe segment 3141 is arranged in the second connecting hole 281A1, thereby ensuring the insulated arrangement between the probe 2352 of the common water level probe 235 and the tank body 21.
