DETAILED DESCRIPTION

[0034] 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.

[0035] Please refer to Figure 1-4 An embodiment of the present application provides a heat and water purification integrated machine 1, which includes a housing assembly 10, a faucet 1A, a hot tank assembly 20 and a filtering system 50.

[0036] The housing assembly 10 has an inner cavity 10A, and the hot tank assembly 20 and the filter system 50 are both installed in the inner cavity 10A, so that the housing assembly 10 can be used to protect the hot tank assembly 20 and the filter system 50, and the probability of damage to the hot tank assembly 20 and the filter system 50 can be reduced. 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 air purifier 1 can have a longer service life. The material of the housing assembly 10 can also be plastic, which can reduce its weight and material cost while ensuring the structural strength.

[0037] The faucet 1A is connected to the housing assembly 10 and is in communication with the hot tank assembly 20 and the filter system 50. When the faucet 1A is turned on, the hot water in the hot tank assembly 20 or the normal temperature water in the filter system 50 can flow out through the faucet 1A to provide hot water or normal temperature water to the user. It is understandable that the heat and water purifier 1 can have two faucets 1A, one faucet 1A is in communication with the hot tank assembly 20, and the other faucet 1A is in communication with the filter system 50, so that hot water and normal temperature water can be provided to the user separately. In other embodiments, the faucet 1A can also be in communication with the hot tank assembly 20 and the filter system 50 respectively, and the faucet 1A is controlled by a switch to flow out hot water or normal temperature water.

[0038] It is understandable that the faucet 1A can also be a smart faucet 1A. When the controller detects a signal for taking normal temperature water at the smart faucet 1A or a water replenishment signal from the hot tank assembly 20, the controller can control the filtration system 50 to start water production to ensure that the user can obtain normal temperature water and hot water from the smart faucet 1A in a timely manner, thereby reducing the user's waiting time and improving the user's experience.

[0039] The hot tank assembly 20 is connected to the faucet 1A and the filtering system 50, and can heat the room temperature water after being filtered by the filtering system 50, and provide hot water to the user after the faucet 1A is turned on.

[0040] The filter system 50 can be connected to the tap water pipe, and the filter system 50 includes a filter element, a booster pump 55, and a water inlet solenoid valve. The booster pump 55 and the solenoid valve are both electrically connected to the controller. When the controller detects that there is a signal for taking normal temperature water at the faucet 1A or a water replenishment signal for the hot tank assembly 20, the filter system 50 is controlled to start water production. When these two signals disappear, the controller controls the filter system 50 to stop water production and enter a standby state. The normal temperature 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 1A. Of course, when the user needs to take normal temperature water, the water replenishment valve 251 can also be opened, that is, the filter system 50 can also meet the needs of making normal temperature water and replenishing water for the hot tank assembly 20 at the same time.

[0041] Please refer to Figure 1-4 It can be understood that the faucet 1A can also be installed near the operation panel and connected to the hot tank assembly 20 and the filtering system 50 through a pipeline, so that the user can control the water output of the faucet 1A through the operation panel, thereby facilitating the use of hot water and room temperature water from the faucet 1A.

[0042] Exemplarily, the filter system 50 may include a plurality of filter elements, and the plurality of filter elements may be independently provided or integrated into a composite filter element.

[0043] Please refer to Figure 3 Specifically, the filtration system 50 may include an 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 inlet valve 51 is connected to the raw water inlet, the water outlet end of the inlet valve 51 is connected to the water inlet end of the first filter element 52, the water outlet end of the first filter element 52 is connected to the water inlet end of the booster pump 55, the water outlet end of the booster pump 55 is connected to the water inlet end of the second filter element 53, the water outlet end of the second filter element 53 is connected to the water inlet end of the one-way valve 56, and the water outlet end of the one-way valve 56 is connected to the water outlet end of the filtration system 50.

[0044] The first filter element 52 is used to achieve preliminary filtration of raw water, and can filter out large particles such as mud, rust, insect eggs, and red worms in the raw water. The raw water can be tap water, well water, etc. 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.

[0045] The second filter element 53 has a reverse osmosis membrane, which can be an artificial semipermeable membrane. The pore size of the reverse osmosis membrane is very small, which can effectively remove impurities such as dissolved salts, colloids, microorganisms, and organic matter in the water. A pure water pipe is connected between the second filter element 53 and the faucet 1, so that the user of this application can obtain pure water, that is, room temperature water, after the water is filtered by the second filter element 53 through the faucet 1A. Of course, a waste water pipe 531 is also connected to the second filter element 53, and a waste water valve 532 can be provided on the waste water pipe 531 to control the discharge of waste water.

[0046] 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, and a water outlet end of the third filter element is connected to a water outlet end of the filtration system 50 .

[0047] The third filter element is used to absorb 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.

[0048] 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 normal temperature water to the faucet 1A, 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. When the hot tank assembly 20 needs to be replenished with water, the water replenishment valve 251 is opened, and the normal temperature water at the water outlet of the filter system 50 can enter the hot tank assembly 20. When the user needs to take normal temperature water, the water replenishment valve 251 is closed, and the normal temperature water at the water outlet of the filter system 50 can flow out through the faucet 1A.

[0049] Please refer to Figure 1-4 It can be understood that the heat and water purification machine 1 can also include a pipeline machine 57, and the normal temperature water can also enter the pipeline machine 57 after passing through the one-way valve 56 to supply water to the pipeline machine 57.

[0050] Since the filter system 50 and the hot tank assembly 20 have many parts and the installation sequence lacks systematization, problems such as limited operating space, inaccurate positioning of parts, and difficulty in real-time debugging and testing often occur during the assembly process, 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 framed on the outer periphery of the middle shell 11, and the waterway plate 60, the filter system 50 and the hot tank assembly 20 are all connected to the middle shell 11.

[0051] Based on the above embodiment, by adopting a shell assembly 10 including a middle shell 11 and an outer shell 12, the inner cavity 10A is set in the middle shell 11, and the waterway plate 60, the filter system 50 and the hot tank assembly 20 are all connected to the middle shell 11, which greatly optimizes the assembly process and performance of the heat and air purifier 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 operating space. Workers can more conveniently and accurately position and install the filter system 50 and the hot tank assembly 20, improving assembly efficiency and accuracy. Compared with assembling directly in the outer shell 12, operating on the middle shell 11 can reduce the inconvenience caused by the shape and space limitations of the outer shell 12.

[0052] At the same time, this connection method facilitates the immediate debugging and testing of each component during the assembly process, that is, after the filter system 50 and the hot tank assembly 20 are installed on the middle shell 11, some functional modules on the middle shell 11 can be preliminarily debugged and tested, so that potential problems can be discovered and solved in time, reducing the workload of rework and maintenance, effectively improving the product qualification rate, and reducing production costs. In contrast, if the inspection is carried out after the outer shell 12 is closed, once a problem is found, the outer shell 12 needs to be disassembled for maintenance, which will increase the difficulty and cost of maintenance. From a performance perspective, the stable assembly structure ensures the connection reliability between the waterway plate 60, the filter system 50 and the hot tank assembly 20, ensures the stable transmission of water flow and the effective use of heat, and improves the overall operation stability and reliability of the equipment, thereby providing users with a more stable and efficient integrated heat and clean functional experience.

[0053] Please refer to Figure 1-4 It should be noted that the outer shell 12 and the middle shell 11 are fixed by means of screws or buckles to ensure a tight combination, maintain the stability and protection of the overall structure, and protect the internal components from interference from external factors.

[0054] Please refer to Figure 1-4 Furthermore, the middle shell 11 has an installation cavity 11A and an installation port 11B connected to the installation cavity 11A, and the installation port 11B is used for the filter element of the filter system 50 to pass through and be installed in the installation cavity 11A. It can be understood that when the filter element is passed through the installation port 11B and fixed in the installation cavity 11A, the filter element and the middle shell 11 form a tightly combined integral structure. In this way, the filter element can be effectively prevented from being displaced, loosened or even damaged 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 filtering process can be carried out continuously and efficiently. From the perspective of long-term use, the stable filter element installation method reduces the risk of wear and leakage of the filter medium caused by frequent shaking or displacement of the filter element, extends the service life of the filter element, and reduces the frequency and cost of user replacement of the filter element. At the same time, the stable filtration process also ensures the stability of the purified water quality, provides a solid foundation for the subsequent stable operation of the water plate 60 and the entire heat and water purification machine 1, reduces the potential damage to other parts of the equipment due to water quality fluctuations, reduces the overall maintenance rate and maintenance cost of the heat and water purification machine 1, and improves the durability and performance stability of the heat and water purification machine 1.

[0055] Please refer to Figure 1-4It should be noted that when the filter system 50 includes the first filter element 52 and the second filter element 53, two installation 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 operated in their own independent and adapted spaces, avoiding possible mutual interference and influence between different filter elements, ensuring that each filter element can give full play to its due filtering performance, and improving the filtering accuracy and efficiency of the entire filter system 50.

[0056] Please refer to Figure 1 , Figure 5 and Figure 6 In one embodiment, the hot tank assembly 20 includes a tank body 21 , a heating element 22 and a water pump 30 .

[0057] The tank body 21 has a heating chamber 21A, a water replenishment port 214 and a water extraction port 216. The water replenishment port 214 and the water extraction port 216 are both connected to the heating chamber 21A. The water replenishment port 214 is connected to the water replenishment pipe 25. The water replenishment port 214 is connected to the water replenishment pipe 25, so that when the water replenishment valve 251 is opened, the normal temperature water at the water outlet end of the filtration system 50 can enter the heating chamber 21A through the water replenishment pipe 25 and the water replenishment port 214.

[0058] The heating element 22 is connected to the tank body 21 and is used to heat the water in the heating chamber 21A. Exemplarily, the heating element 22 can be arranged in the tank body 21 so that the heating element 22 can directly heat the water in the heating chamber 21A. Exemplarily, the heating element 22 can be a heating tube. Specifically, the heating tube can be connected to the tank body 21 and extend into the heating chamber 21A. In other embodiments, the heating element 22 can also be arranged outside the tank body 21 to heat the tank body 21, so that the water in the heating chamber 21A can also be heated by heating the tank body 21. In the embodiment of the present application, there is no specific restriction on the setting position of the heating element 22 on the tank body 21 and the specific form of the heating element 22. It can be understood that the tank body 21 can have a length direction X, and the heating element 22 extends along the length direction X of the tank body 21 to ensure that the water in the heating chamber 21A can be evenly heated.

[0059] The inlet of the water pump 30 is connected to the water suction port 216 of the tank body 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 turned on, 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.

[0060] In addition, the heat and water purifier 1 of the present application can also realize the function of the user obtaining the set temperature water temperature, that is, the user can also obtain the warm water function of the temperature between the normal temperature water and the hot water discharged from the hot tank assembly 20 from the faucet 1A. For this purpose, the heat and water purifier 1 of the present application can further include a first temperature sensor and a second temperature sensor. The first temperature sensor is connected to the tank body 21 and is arranged in the heating chamber 21A to detect the temperature of the hot water in the heating chamber 21A. The second temperature sensor is arranged in the pure water pipeline to detect the normal temperature water temperature of the normal temperature water in the pure water pipeline. The first temperature sensor and the second temperature sensor are both connected to the controller. The controller can receive the detection values ​​of the first temperature sensor and the second temperature sensor, and control the operating power of the water pump 30 and the booster pump 55 to form warm water of the set temperature value at the faucet 1A. It can be understood that the first temperature sensor can also be arranged in the water outlet pipe of the tank body 21 to detect the hot water temperature of the hot water in the water outlet pipe of the tank body 21.

[0061] It can be understood that a warm water control device can be provided on the operation panel, and the warm water control device includes at least one of a button, a knob, a touch screen, etc. The user can operate the warm water control device to select the required warm water temperature, so that the faucet 1A can discharge warm water of the user-selected temperature to meet the user's needs.

[0062] In the embodiments of the present application, the selection of warm water at 45° C. and warm water at 55° C. is taken as an example to explain the specific method steps.

[0063] When the user selects warm water temperature through the warm water control device, the controller obtains the temperature selection signal of warm water; if the temperature selection signal is a 45°C warm water signal, the controller controls the boost pump 55 to adjust the duty cycle to 85%, the controller obtains the current room temperature 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 cycle of the water pump 30 according to the first preset formula, and the controller adjusts the output duty cycle of the water pump 30 according to the first output duty cycle value. At this time, 45°C warm water can flow out of the water outlet of the faucet 1A; when the controller detects that the water level of the tank 21 drops to a low water level, or when the controller receives a closing signal of the faucet 1A, the controller controls the water outlet of the faucet 1A to stop draining water.

[0064] If the temperature selection signal is not a 45°C warm water signal, it indicates that the user selects 55°C warm water. The controller controls the boost pump 55 to adjust the duty cycle to 75%. The controller obtains the current room temperature water temperature through the first temperature sensor, and obtains the current hot water temperature through the second temperature sensor. The second output duty cycle of the water pump 30 is calculated according to the second preset formula. The controller adjusts the output duty cycle of the water pump 30 according to the second output duty cycle value. At this time, 55°C warm water can flow out of the water outlet of the faucet 1A; when the controller detects that the water level of the tank 21 drops to a low water level, or when the controller receives a closing signal from the faucet 1A, the controller controls the water outlet of the faucet 1A to stop draining water.

[0065] It is understandable that in other embodiments, the operation panel may also provide other warm water temperature options, such as 35°C, 50°C, and 60°C, etc. In the embodiments of the present application, there is no specific limitation on this.

[0066] Please refer to Figure 1 , Figure 5 and Figure 6 In order to facilitate the detection of the water level in the heating chamber 21A, the hot tank assembly 20 further includes 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 connected through the water in the heating chamber 21A, the controller can receive a high water level signal, thereby determining that the water in the heating chamber 21A is in a high water level state. When the high water level probe 233 and the common water level probe 235 are not connected through the water in the heating chamber 21A, and the low water level probe 234 and the common water level probe 235 are connected through the water in the heating chamber 21A, the controller can receive an intermediate water level signal, thereby determining that the water in the heating chamber 21A is in an intermediate water level. When the low water level probe 234 and the common water level probe 235 are not connected through the water in the heating chamber 21A, the controller can receive a low water level signal, thereby determining that the water in the heating chamber 21A is in a low water level.

[0067] It is understandable that in other embodiments, the liquid level in the heating chamber 21A can also be detected by a float. Of course, the liquid level in the heating chamber 21A can also be detected by a Hall sensor. In the implementation of this application, no further details will be given.

[0068] 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. However, since the heating element 22 is also connected to the tank body 21, the working voltage of the heating element 22 is much higher than the working voltage 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 to the ground terminal of the tank body 21, which will cause the common water level probe 235 to be easily broken down by the working voltage of the heating element 22, causing damage to the common water level probe 235, affecting the detection accuracy of the water level height in the heating chamber 21A, and affecting the service life of the heat and water purification machine 1.

[0069] Please refer to Figure 1 , Figure 5 and Figure 6 In the embodiment of 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 connected to the water suction port 216, and the water outlet pipe 31 is connected to the outlet of the pump body 30A; the common water level probe 235 is connected to the water outlet pipe 31, and the common water level probe 235 includes a probe 2352, the probe 2352 is insulated from the tank body 21, and the probe 2352 extends into the water outlet pipe 31, so that the probe 2352 can be connected to the high water level probe 233 and the low water level probe 234 through the water outlet pipe 31, the pump body 30A and the water in the heating chamber 21A, so as to detect the water level in the heating chamber 21A. And because the common water level probe 235 is arranged on the water outlet pipe 31, and the probe 2352 is insulated from the tank body 21, 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, and the air conditioner and heat all-in-one machine 1 can have a longer service life, so as to ensure the accuracy of the water level height in the heating chamber 21A detected by the high water level probe 233, the low water level probe 234 and the common water level probe 235.

[0070] Moreover, when air blockage occurs in the pump body 30A, bubbles exist in the pump body 30A and the water outlet pipe 31. Since the common water level probe 235 is arranged on the water outlet pipe 31, the presence of bubbles will cause 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 will produce abnormal changes, so that the controller can determine that air blockage occurs in the pump body 30A according to the abnormal changes, so as to control the driving part to stop working or reduce the working power, so as to reduce the probability of the driving part idling and burning out, and thus the water pump 30 can have a longer service life, so that the heat and water purification integrated machine 1 can have a longer service life.

[0071] Example 1: Please refer to Figure 1 , Figure 5 and Figure 6In one embodiment, the pump body 30A includes an insulating pump housing 30A1 and a driving member (not shown) disposed in the insulating pump housing 30A1, the insulating pump housing 30A1 is connected to the tank body 21, the water outlet pipe 31 includes 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 to 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 to the tank body 21 through the insulating pump housing 30A1, the common water level probe 235 is insulated from the tank body 21, and further the common water level probe 235 is insulated from the heating element 22, so as to reduce the probability of damage to the common water level probe 235.

[0072] It is understandable that when the common water level probe 235 is in the water outlet pipe 31, since the common water level probe 235 needs to be electrically connected to the high water level probe 233 and the low water level probe 234 through the water outlet pipe 31, the insulating pump housing 30A1 and the water in the heating chamber 21A, it is necessary for the water between the inlet and outlet of the pump body 30A to remain in a connected state. In the embodiment of the present application, the pump body 30A is a water pump without forward and reverse check function, such as a vane pump, and the driving member is a vane disposed in the pump housing.

[0073] It can be understood that in order to ensure that the common water level probe 235 can form a detection circuit 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, thereby ensuring 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 chamber 21A.

[0074] It is understandable that the insulating pump housing 30A1 is a pump housing made of insulating material, and the insulating material may be, but is not limited to, polyvinyl chloride (PVC), polyethylene (PE), epoxy resin (EP), fiber reinforced plastics (FRP), glass fiber, and silicone rubber. Similarly, the insulating water outlet pipe 312 is a water outlet pipe 31 made of insulating material. Similar statements in the following text will not be repeated.

[0075] Please refer to Figure 1 , Figure 5 and Figure 6In another specific embodiment, the pump body 30A includes a metal pump shell 30A2 and a driving component arranged in the metal pump shell 30A2, the metal pump shell 30A2 is connected to the tank body 21, the water outlet pipe 31 includes an insulating water outlet pipe 312, and the common water level probe 235 is connected to the insulating water outlet pipe 312, which can also insulate the common water level probe 235 from the tank body 21, and further insulate the common water level probe 235 from the heating element 22 to reduce the probability of damage to the common water level probe 235.

[0076] Please refer to Figure 1 , Figure 5 and Figure 6 In another specific embodiment, the pump body 30A includes a metal pump shell 30A2 and a driving component arranged in the metal pump shell 30A2, the metal pump shell 30A2 is connected to the tank body 21, the water outlet pipe 31 includes a metal water outlet pipe 311, the common water level probe 235 also includes an insulating sheath 2351, the probe 2352 passes through the insulating sheath 2351, and the insulating sheath 2351 is connected to the metal water outlet pipe 311, which can also insulate the probe 2352 from the tank body 21, and further insulate the probe 2352 from the heating element 22, so as to reduce the probability of damage to the common water level probe 235.

[0077] It is understandable that when the common water level probe 235 includes the insulating covering shell 2351 , the pump body 30A may also include an insulating pump shell 30A1 , and the water outlet pipe 31 may also include an insulating water outlet pipe 312 , which will not be elaborated herein.

[0078] Please refer to Figure 1 , Figure 5 and Figure 6 In another specific embodiment, the pump body 30A includes a metal pump shell 30A2 and a driving component arranged in the metal pump shell 30A2, the metal pump shell 30A2 is connected to the tank body 21, the water outlet pipe 31 includes a metal water outlet pipe 311, and the hot tank assembly 20 also includes a first insulating mounting structure 28, the first insulating mounting structure 28 is connected to the metal water outlet pipe 311, and the common water level probe 235 is connected to the first insulating mounting structure 28, so that the common water level probe 235 can be insulated from the tank body 21, and the probe 2352 and the heating element 22 are insulated to reduce the probability of damage to the common water level probe 235.

[0079] Please refer to Figure 1 , Figure 5-7 It can be understood that when the common water level probe 235 is insulated from the tank body 21 through the first insulating mounting structure 28, the pump body 30A may also include an insulating pump casing 30A1, and the water outlet pipe 31 may also include an insulating water outlet pipe 312, which will not be elaborated herein.

[0080] Please refer to Figure 1 , Figure 5-7 Specifically, the water outlet pipe 31 may have a first mounting hole 31A, the first insulating mounting structure 28 includes a first insulating seal 28A, the first insulating seal 28A is connected to the inner wall of the first mounting hole 31A, the first insulating seal 28A has a first connecting hole 28A1, the common water level probe 235 is connected to the inner wall of the first connecting hole 28A1, and the probe 2352 of the common water level probe 235 passes through the first connecting hole 28A1 and the first mounting hole 31A, and is arranged in the water outlet pipe 31, thereby achieving an insulation setting between the probe 2352 of the common water level probe 235 and the tank body 21. Exemplarily, the first insulating seal 28A may be an insulating sealing ring, which is sleeved on the outer peripheral side of the common water level probe 235, and the outer peripheral side of the insulating sealing ring is connected to the inner wall of the first mounting hole 31A.

[0081] It is understood that the hot tank assembly 20 may also include a mounting bracket 29 (see Fig.12 ), the mounting bracket 29 is connected to 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 to the insulating cover 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 this case, a suitable common water level probe 235 form can be selected according to the pump housing 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.

[0082] Example 2: Please refer to Figure 1 and Figure 8 In one embodiment, the hot tank assembly 20 may further include a wire 2354, at least one of the water outlet pipe 31 and the pump casing includes a metal segment 2353, the metal segment 2353 is insulated from the tank body 21, the wire 2354 is connected to the metal segment 2353, the wire 2354 and the metal segment 2353 together constitute a common water level probe 235, which can also cooperate with the high water level probe 233 and the low water level probe 234 to realize water level detection of the heating chamber 21A.

[0083] It can be understood that the height of the metal segment 2353 near one end of the tank body 21 is lower than the end height of the low water level probe 234, thereby ensuring 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 chamber 21A.

[0084] Please refer to Figure 1 and Figure 8In a specific embodiment, the pump body 30A includes an insulating pump casing 30A1, which is connected to the tank body 21. The water outlet pipe 31 at least includes a metal water outlet pipe 311, which is connected to the insulating pump casing 30A1, and the wire 2354 is connected to the metal water outlet pipe 311; the metal water outlet pipe 311 is a metal segment 2353, so that the metal water outlet pipe 311 can form a common water level probe 2355 with the wire 2354, and is insulated from the tank body 21 by the insulating pump casing 30A1 to reduce the probability of damage to the common water level probe 2355.

[0085] Please refer to Figure 1 and Figure 8 In another specific embodiment, the pump body 30A includes a metal pump shell 30A2, the metal pump shell 30A2 is connected to the tank body 21, the water outlet pipe 31 includes an insulating water outlet pipe 312 and a metal water outlet pipe 311, the insulating water outlet pipe 312 is connected to the metal pump shell 30A2, the metal water outlet pipe 311 is communicated with the insulating 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 can form a common water level probe 235 with the wire 2354, and is insulated from the tank body 21 through the insulating water outlet pipe 312 to reduce the probability of damage to the common water level probe 2355.

[0086] Please refer to Figure 1 , Figure 6 and Figure 8 In one embodiment, in order to increase the temperature of the first cup of water taken by the user, the tank body 21 includes 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 a heating chamber 21A. The water extraction port 216 can be set on the tank body 211 (please refer to Figure 6 ), the water extraction port 216 can also be brought closer to the heating element 22, so that the temperature of the extracted water can be higher, thereby increasing the temperature of the first cup of water taken by the user.

[0087] It is understandable that the specific form of connection between the inlet of the pump body 30A and the tank body 211 can be at least one of screw connection, clamping connection and welding. In other embodiments, the inlet of the pump body 30A can also be connected to the tank body 211 through a pipeline and communicated with the water suction port 216. In the embodiment of the present application, the connection form between the inlet of the pump body 30A and the tank body 211 is not limited.

[0088] It is understandable that the water extraction port 216 can also be convexly arranged on the tank bottom cover 213, so that the water extraction port 216 can be closer to the heating element 22, so that the temperature of the water extracted by the pump body 30A can be higher, and then the temperature of the first cup of water taken by the user can be increased, so as to improve the user's experience of getting hot water. In this case, the pump body 30A is directly bolted to the tank bottom cover 213, so that the inlet of the pump body 30A is connected to the water extraction port 216.

[0089] Please refer to Figure 1 , Figure 6 and Figure 8 For example, the height difference between the center of the water extraction port 216 and the tank bottom cover 213 is H1. When H1 satisfies 5mm≤H1≤10mm, the water extraction port 216 can be closer to the heating element 22, so that the temperature of the water extracted by the pump body 30A is higher, thereby improving the temperature of the first cup of water taken by the user. In addition, the user can take as much hot water in the heating chamber 21A as possible, which can improve the utilization rate of the hot water in the heating chamber 21A.

[0090] If H1 is less than 5 mm, the water extraction port 216 is far away from the heating element 22 , resulting in a lower temperature of the water extracted by the pump body 30A, and a lower temperature of the first cup of water taken by the user.

[0091] If H1>10mm, the water outlet 216 is higher, so when the user cannot get hot water from the faucet 1A, there is still a lot of hot water remaining in the heating chamber 21A, resulting in a low utilization rate of the hot water in the heating chamber 21A, which easily causes a waste of resources.

[0092] Please refer to Figure 1 , Fig. 9 and Fig.10 In another embodiment, in order to increase the temperature of the first cup of water taken by the user, the present application can also pass the water outlet pipe 31 through the tank body 21, and then connect the pipe with the faucet 1A, so as to use the water in the heating chamber 21A to perform secondary heating on the water in the water outlet pipe 31, and also keep the residual water in the water outlet pipe 31 warm, so that the temperature of the first cup of water taken by the user from the faucet 1A can be higher, so as to improve the user's experience of taking hot water.

[0093] Please refer to Figure 1 , Fig. 9 and Fig.10Specifically, the tank bottom cover 213 has a first through hole 213A, the tank top cover 212 has a second through hole 212A, the water outlet pipe 31 includes a first pipe section 313 and a second pipe section 314, the first pipe section 313 is connected to the outlet of the pump body 30A, and the first pipe section 313 is arranged outside the tank body 21; the second pipe section 314 is connected to the first pipe section 313, and the second pipe section 314 penetrates into the heating chamber 21A from the first through hole 213A, and passes out of the heating chamber 21A from the second through hole 212A, and then connects to the faucet 1A, so that when the user turns on the faucet 1A, the pump body 30A can pump out the water in the heating chamber 21A and pass through the heating chamber 21A again in the water outlet pipe 31, so that the temperature of the first cup of water when the user takes hot water can be higher, so as to improve the user's experience of taking hot water.

[0094] Please refer to Figure 1 , Fig. 9 and Fig.10 In one embodiment, the common water level probe 235 is disposed in the first pipe section 313 .

[0095] Please refer to Figure 1 , Fig. 9 and Fig.10 In a specific embodiment, the probe 2352 extends into the first pipe section 313 so that the probe 2352 can come into contact with water, thereby enabling the probe 2352 to communicate with the high water level probe 233 and the low water level probe 234 via the first pipe section 313, the pump housing, and the water in the heating chamber 21A, thereby enabling the high water level probe 233 and the low water level probe 234 to cooperate with the common water level probe 235 to detect the liquid level in the heating chamber 21A.

[0096] Please refer to Figure 1 , Fig. 9 and Fig.10 In a specific embodiment, the first pipe segment 313 includes a first metal pipe segment 3131, the second pipe segment 314 includes a second metal pipe segment 3141, and the insulating sheath 2351 is connected to the first metal pipe segment 3131 so that the probe 2352 can maintain an insulated setting from the tank body 21, thereby reducing the probability of damage to the common water level probe 235.

[0097] Please refer to Figure 1 , Fig. 9 and Fig.10In another specific embodiment, the first pipe segment 313 includes a first metal pipe segment 3131, and the second pipe segment 314 includes a second metal pipe segment 3141; the hot tank assembly 20 also includes a second insulating mounting structure (not shown in the figure), which is connected to the tank bottom cover 213 and the tank top cover 212, and is arranged at the first through hole 213A and the second through hole 212A, and is connected to the second metal pipe segment 3141, so that the second metal pipe segment 3141 can remain insulated from the tank body 21, thereby allowing the probe 2352 to be insulated from the tank body 21.

[0098] Specifically, the second insulating installation structure may include two second insulating seals (not shown in the figure), the two second insulating seals are respectively connected to 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, each second insulating seal has a second connection hole 281A1, and the second metal pipe section 3141 is penetrated through the second connection hole 281A1, thereby ensuring the insulation setting between the probe 2352 of the common water level probe 235 and the tank body 21. Exemplarily, the second insulating seal may be an insulating sealing ring, the two insulating sealing rings are both sleeved on the outer peripheral side of the second metal pipe section 3141, and the outer peripheral sides of the two insulating sealing rings are respectively connected to the inner wall of the first through hole 213A and the second through hole 212A.

[0099] It is understandable that when the second metal pipe section 3141 is connected to the tank body 21 through the second insulating seal, the first pipe section 313 may further include a first insulating pipe section 3132, and the second pipe section 314 may further include a second insulating pipe section 3142. No further details will be given here.

[0100] It can be understood that when the first pipe segment 313 includes the first insulating pipe segment 3132, the second pipe segment 314 can include at least one of the second metal pipe segment 3141 and the second insulating pipe segment 3142, and the common water level probe 235 is connected to the first insulating pipe segment 3132, so that the probe 2352 can remain insulated from the tank body 21.

[0101] Please refer to Figure 1 , Fig. 9 and Fig.10 In one embodiment, the metal segment 2353 may be disposed on the first pipe segment 313 so that the wire 2354 can form a common water level probe 235 when connected to the metal segment 2353 .

[0102] Please refer to Figure 1 , Fig. 9 and Fig.10In a specific embodiment, the first pipe segment 313 includes a first metal pipe segment 3131, the second pipe segment 314 includes a second metal pipe segment 3141, and the metal segment 2353 is arranged on the first metal pipe segment 3131; at this time, the second metal pipe segment 3141 is connected to the inner wall of the first through hole 213A and the second through hole 212A through a second insulating mounting structure, so that the common water level probe 235 can maintain an insulated setting from the tank body 21.

[0103] Please refer to Figure 1 , Fig. 9 and Fig.10 It can be understood that the second pipe section 314 can also include a second insulating pipe section 3142, which can also be connected to the inner walls of the first through hole 213A and the second through hole 212A through a second insulating mounting structure, and can also enable the common water level probe 235 to remain insulated from the tank body 21.

[0104] Please refer to Figure 1 and Figure 4 Since the heating element 22 easily generates gas in the heating chamber 21A when heating the water in the heating chamber 21A, causing the pressure in the heating chamber 21A to increase, in order to facilitate the exhaust of the heating chamber 21A, the tank top cover 212 can be connected to an exhaust pipe 24, and the exhaust pipe 24 is connected to the heating chamber 21A to facilitate the exhaust of the gas in the heating chamber 21A.

[0105] It is understandable that the exhaust pipe 24 can be directly discharged to the atmosphere, or it can be connected to the faucet 1A to exhaust when the faucet 1A is turned on. In the embodiment of the present application, there is no specific limitation on the way in which the heating chamber 21A is exhausted through the exhaust pipe 24.

[0106] Please refer to Figure 1 , Figure 5 and Figure 9-11 In the embodiment of the present application, in order to simplify the pipeline structure of the tank top cover 212, the hot tank assembly 20 further includes a three-way pipe 26, the three-way pipe 26 has a tube cavity 26A and an air inlet 26B, an exhaust port 26C and a water outlet 26D connected to the tube cavity 26A, the air inlet 26B is connected to the second through hole 212A; the end of the second pipe section 314 away from the first through hole 213A passes through the second through hole 212A and the air inlet 26B, and is arranged in the tube cavity 26A, and is connected to the water outlet 26 D is connected, one end of the second pipe section 314 away from the first through hole 213A is sealed and connected to the inner wall of the water outlet 26D, and the inner wall of the second through hole 212A and the inner wall of the air inlet 26B are both spaced apart from the outer wall of the second pipe section 314; wherein, the inner wall of the tube cavity 26A and the outer wall of the second pipe section 314 are surrounded to form an exhaust channel 26E, and the gas in the heating cavity 21A can be discharged in sequence through the second through hole 212A, the air inlet 26B, the exhaust channel 26E and the exhaust port 26C.

[0107] It is understandable that the three-way tube 26 can be a silicone tube to improve the tightness of the connection between the three-way tube 26 and the inner wall of the second through hole 212A, and also ensure that the probe 2352 and the tank body 21 are kept insulated.

[0108] Please refer to Figure 1 , Fig.12 and Fig.13 In one embodiment, in order to drain the hot water in the heating chamber 21A and clean the heating chamber 21A, the hot tank assembly 20 may further include a drain pipe 27 and a drain valve (not shown in the figure), and the tank bottom cover 213 is provided with a drain port 217 (see Figure 6 ), the drain port 217 is connected to the heating chamber 21A, and the drain pipe 27 is connected to the drain port 217. When the heating chamber 21A does not need to be cleaned, the drain valve is closed. When the heating chamber 21A needs to be cleaned, the drain valve is opened to drain the hot water in the heating chamber 21A through the drain pipe 27, thereby facilitating the cleaning of the heating chamber 21A, and providing reliable protection for the user's drinking water health.

[0109] Example 3: Please refer to Figure 1 , Fig.12 and Fig.13 In one embodiment, the common water level probe 235 can also be disposed in the drain pipe 27, and the probe 2352 extends into the drain pipe 27 and is insulated from the tank body 21. The probe 2352 can be connected to the high water level probe 233 and the low water level probe 234 via the drain pipe 27 and the water in the heating chamber 21A, thereby detecting the water level in the heating chamber 21A.

[0110] Please refer to Figure 1 , Fig.12 and Fig.13 In a specific embodiment, the drain pipe 27 includes a metal drain pipe 271, which is connected to the drain port 217; the common water level probe 235 is insulated and connected to the metal drain pipe 271, and the probe 2352 extends into the metal drain pipe 271 so that the probe 2352 can be connected to the high water level probe 233 and the low water level probe 234 via the metal drain pipe 271 and the water in the heating chamber 21A.

[0111] Please refer to Figure 1 , Fig.12 and Fig.13 Specifically, the common water level probe 235 can be connected to the metal drain pipe 271 via the insulating covering shell 2351, thereby achieving an insulation setting with the tank body 21.
