DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the 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.

[0030] Please refer to Figures 1-2The embodiment of the present application provides a net heat all-in-one machine 1, which is a device integrating water purification and heating functions. The net heat all-in-one machine 1 comprises a shell assembly 10, a hot tank assembly 20 and a filtering system 50.

[0031] The shell assembly 10 has an inner cavity 101, and the hot tank assembly 20 and the filtering system 50 are both installed in the inner cavity 101; that is, the inner cavity 101 can be divided into a hot tank cavity 102 and a filtering cavity 103, and the hot tank cavity 102 and the filtering cavity 103 are arranged separately, wherein the hot tank assembly 20 is installed in the hot tank cavity 102, and the filtering system 50 is installed in the filtering cavity 103, so as to protect the hot tank assembly 20 and the filtering system 50 by using the shell assembly 10, thereby reducing 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, thereby reducing the probability of damage of the shell assembly 10, and further reducing 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. Of course, the material of the shell assembly 10 can also be plastic, which has the advantages of high structural strength, light weight and low cost.

[0032] Please refer to Figures 2-3 Further, the net heat all-in-one machine 1 further comprises a faucet 2, which can be connected to the shell assembly 10 through a pipeline; that is, the water outlet end of the hot tank assembly 20 and the water outlet end of the filtering system 50 can be arranged on the shell assembly 10, and the faucet 2 is communicated with the water outlet end of the hot tank assembly 20 and the water outlet end of the filtering system 50 on the shell assembly 10 through a pipeline, so that the faucet 2 is communicated with the hot tank assembly 20 and the filtering system 50, and when the faucet 2 is opened, hot water in the hot tank assembly 20 or normal temperature water in the filtering system 50 can flow out through the faucet 2 to provide hot water or normal temperature water for users. It can be understood that the net heat all-in-one machine 1 can have two faucets 2, one of which is communicated with the hot tank assembly 20, and the other of which is communicated with the filtering system 50, so as to provide hot water and normal temperature water for users separately. In other embodiments, the faucet 2 can also be communicated with the hot tank assembly 20 and the filtering system 50 respectively, and the faucet 2 can flow out hot water or normal temperature water by controlling the switch.

[0033] It can be understood that the faucet 2 can also be an intelligent faucet 2, and when the controller 80 detects a normal temperature water taking signal or a hot tank assembly 20 water replenishing signal at the intelligent faucet 2, the controller 80 can control the filtering system 50 to start water making, so as to ensure that users can take normal temperature water and hot water from the intelligent faucet 2 in time, reduce the waiting time of users, and improve the use experience of users.

[0034] The hot tank assembly 20 is in communication with the faucet 2, and the hot tank assembly 20 is in communication with the filter system 50, the hot tank assembly 20 can heat the liquid filtered by the filter system 50, and provide hot water for the user after the faucet 2 is opened.

[0035] Please refer to Figure 3 The filter system 50 can be connected with a tap water pipe, the filter system 50 includes a filter core, a booster pump 54, and a water inlet valve 51. The booster pump 54 and the water inlet valve 51 are electrically connected with the controller 80, and when the controller 80 detects a normal temperature water taking signal at the faucet 2 or a water replenishing signal of the hot tank assembly 20, the controller 80 controls the filter system 50 to start water production, and when the two signals disappear, the controller 80 controls the filter system 50 to stop water production and enter a standby state. The pure water at the water outlet end of the filter system 50 can enter the hot tank assembly 20, or directly flow out through the faucet 2.

[0036] For example, the filter system 50 can include multiple filter cores, which can be independently arranged or integrated into a composite filter core.

[0037] Please continue to refer to Figure 3 Specifically, the filter system 50 can include a water inlet valve 51, a first filter core 52, a second filter core 53, a booster pump 54, and a one-way valve 55. The water inlet end of the water inlet valve 51 is in communication with the raw water inlet, the water outlet end of the water inlet valve 51 is in communication with the water inlet end of the first filter core 52, the water outlet end of the first filter core 52 is in communication with the water inlet end of the booster pump 54, the water outlet end of the booster pump 54 is in communication with the water inlet end of the second filter core 53, the water outlet end of the second filter core 53 is in communication with the water inlet end of the one-way valve 55, and the water outlet end of the one-way valve 55 is in communication with the water outlet end of the filter system 50.

[0038] The first filter core 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. The first filter core 52 can be a PP cotton filter core (polypropylene melt-blown filter core), a carbon rod filter core, a composite filter core, etc.

[0039] The second filter core 53 has a reverse osmosis membrane, which can be an artificial semi-permeable membrane. The membrane pore size of the reverse osmosis membrane is very small, and can effectively remove impurities such as dissolved salts, colloids, microorganisms, and organic matter in water. The water obtained by the user through the faucet 2 after being filtered by the second filter core 53 can be pure water, that is, a pure water outlet pipe is connected between the second filter core 53 and the faucet 1. Of course, a waste water pipe 531 is also connected to the second filter core 53, and a waste water solenoid valve 532 can be provided on the waste water pipe for controlling the discharge of waste water.

[0040] In other embodiments, the filtering system 50 can further comprise a third filter element, a water inlet end of the third filter element being in communication with a water outlet end of the second filter element 53, and a water outlet end of the third filter element being in communication with the water outlet end of the filtering system 50.

[0041] The third filter element is used for adsorbing odor and residual chlorine, and can be used for improving the taste of the normal temperature water. The third filter element can be an activated carbon filter element.

[0042] Of course, in other embodiments, the filtering system 50 can further be in communication with the pipeline machine 3 through a pipeline; that is, the water outlet end of the filtering system 50 and the pipeline machine 3 are connected through the pipeline, so as to provide the pipeline machine 3 with normal temperature water.

[0043] The hot tank assembly 20 will be described in detail below.

[0044] Referring to Figures 4-6 The hot tank assembly 20 can comprise a tank body 21 and a heating element 22. The tank body 21 has a heating cavity 21a which can be used for carrying liquid, and the heating element 22 is connected with the tank body 21 and used for heating the liquid in the heating cavity 21a. It can be understood that the heating element 22 can be installed on or near the outer wall surface of the tank body 21, so as to transfer heat to the liquid in the heating cavity 21a through heat conduction, so that the liquid in the heating cavity 21a can be heated; or the heating element 22 is installed in the heating cavity 21a and connected with the tank body 21, so that the heating element 22 can directly heat the liquid in the heating cavity 21a, and the embodiments of the present application do not make specific limitation thereon.

[0045] Referring to Figure 2 Further, the hot water integrated machine 1 can further comprise a controller 80. When the heating element 22 is located in the heating cavity 21a, the terminal 221 of the heating element 22 can penetrate the tank body 21, so that the terminal 221 extends out of the outer wall surface of the tank body 21, so as to facilitate the electrical connection between the controller 80 and the terminal 221, thereby facilitating the controller 80 to control the heating element 22 to work according to the set program, so as to heat the liquid in the heating cavity 21a.

[0046] Referring to Figure 4 and Figure 6The hot tank assembly 20 further comprises an exhaust pipe 24 connected with the tank body 21 and communicating with the heating cavity 21a. It can be understood that the heating element 22 heats the liquid in the heating cavity 21a when working, so that part of the water in the heating cavity 21a is converted into water vapor, thereby causing the internal pressure of the heating cavity 21a to rise. If the water vapor in the heating cavity 21a cannot be discharged in time, it may cause the internal pressure of the hot tank assembly 20 to be too large, thereby causing safety hazards such as rupture or water leakage of the hot tank assembly 20. Therefore, the exhaust pipe 24 communicating with the heating cavity 21a is arranged in the embodiment of the present application, which can be used to discharge the water vapor generated in the heating process of the liquid in the heating cavity 21a, so as to ensure the safety of the tank body 21. In addition, after the water vapor in the heating cavity 21a is discharged from the exhaust pipe 24, the air content in the heating cavity 21a can be reduced, so that the heat can more concentratedly act on the water molecules, thereby improving the heating efficiency of the tank body 21.

[0047] The material of the exhaust pipe 24 can include silica gel; that is, silica gel material is widely used in the exhaust pipe 24 of the water dispenser due to its excellent high-temperature resistance, corrosion resistance and flexibility. It not only can withstand the impact of high-temperature water vapor inside the tank body 21 and is not easy to deform or damage, but also can adapt to the complex structure layout inside the net heat all-in-one machine 1, ensure tight connection and no air leakage. In addition, the silica gel material is non-toxic and odorless, which meets the food safety standards.

[0048] In the related art, the exhaust port of the exhaust pipe 24 communicates with the faucet 2; that is, when the user needs to take hot water, the user opens the faucet 2, and the water vapor is discharged first or the water vapor is discharged together with the hot water. At this time, due to the high temperature of the water vapor, the user is easy to be scalded when the water vapor is sprayed out of the faucet 2; at the same time, when the user does not use the net heat all-in-one machine 1, and a large amount of water vapor is generated in the heating cavity 21a, a large amount of water vapor will flow to the faucet 2 from the exhaust pipe 24, and the temperature at the faucet 2 is lower than the temperature in the heating cavity 21a, so that a large amount of water vapor will become water droplets and be discharged from the faucet 2, thereby causing waste of water source and frequent dripping of the faucet 2.

[0049] Please continue to refer to Figure 4 and Figure 6To solve the above problems, the hot tank assembly 20 further comprises a condensing pipe 28, the condensing pipe 28 has a condensing cavity 281 capable of carrying cooling water, and a part of the exhaust pipe 24 is arranged in the condensing cavity 281, so that the part of the exhaust pipe 24 is located in the condensing cavity 281, so that the water vapor in the exhaust pipe 24 can be cooled and condensed by the cooling water during flowing through the condensing cavity 281, at this time, the water vapor flowing through the condensing cavity 281 is condensed into water droplets, and under the action of gravity, the water droplets flow back to the heating cavity 21a from the exhaust pipe 24; that is, by extending the part of the exhaust pipe 24 into the condensing cavity 281 of the condensing pipe 28, so that the cooling water in the condensing cavity 281 can condense the water vapor flowing through the condensing cavity 281, so that most of the water vapor is condensed into water droplets, so that the amount of water vapor sprayed from the faucet 2 can be greatly reduced to avoid scalding the user by high-temperature water vapor, thereby improving the safety of the water heating integrated machine 1. Furthermore, since the water vapor in the exhaust pipe 24 can be cooled and condensed by the cooling water during flowing through the condensing cavity 281, the water vapor is condensed into water droplets, and under the action of gravity, the water droplets flow back to the heating cavity 21a from the exhaust pipe 24, so that the possibility of frequent dripping of the faucet 2 can be reduced to reduce the waste of water source. The material of the condensing pipe 28 can include stainless steel, copper and aluminum, etc., and the embodiments of the present application do not specifically limit the material of the condensing pipe 28.

[0050] It should be noted that the cooling water can be normal temperature water filtered by the filtering system 50.

[0051] The embodiments of the present application set the part of the exhaust pipe 24 arranged in the condensing cavity 281 of the condensing pipe 28, so that most of the water vapor in the exhaust pipe 24 is cooled and condensed into water droplets by the cooling water in the condensing cavity 281 during flowing through the condensing cavity 281, so that the water droplets flow back to the heating cavity 21a due to gravity, so that the water droplets are reused, thereby reducing the waste of water source and the influence caused by the overflow of water vapor. In particular, when the water heating integrated machine 1 is connected with the faucet 2, due to the arrangement of the condensing pipe 28, not only can the possibility of dripping of the faucet 2 be reduced, but also the amount of water vapor sprayed from the faucet 2 can be greatly reduced to avoid scalding the user by high-temperature water vapor, so that the safety of the water heating integrated machine 1 is improved to improve the use effect of the water heating integrated machine 1.

[0052] It should be noted that the embodiments of the present application do not make specific limitation on the type of the heating element 22. Exemplarily, the heating element 22 can be an electric heating wire heating element 22, a Positive Temperature Coefficient (PTC) ceramic sheet heating element 22, or the like. The electric heating wire heating element 22 converts electric energy into heat energy by using the heat effect of electric current to heat the liquid in the heating cavity 21a; the PTC ceramic sheet heating element 22 uses the constant temperature heating characteristic of PTC thermistor to heat the liquid in the heating cavity 21a at constant temperature.

[0053] Please refer to Figure 6 In some embodiments, the condensing pipe 28 has a water inlet 282 and a water outlet 283, both of which are in communication with the condensing cavity 281, and the water inlet 282 is used to access the cooling water.

[0054] Further, the hot tank assembly 20 further comprises a water inlet pipe 25, one end of which is connected with the tank body 21 and in communication with the heating cavity 21a, and the other end of which is connected with the condensing pipe 28 and in communication with the water outlet 283. It can be understood that, in order to facilitate the injection of liquid into the heating cavity 21a, the hot tank assembly 20 is further provided with the water inlet pipe 25 connected with the tank body 21, and one end of the water inlet pipe 25 is in communication with the heating cavity 21a, and the other end of the water inlet pipe 25 is in communication with the water outlet 283, so that when it is necessary to replenish the tank body 21 with water, the cooling water enters the condensing cavity 281 from the water inlet 282, and then flows into the heating cavity 21a from the water outlet 283 and through the water inlet pipe 25, so as to replenish the heating cavity 21a with water.

[0055] Further, since the other end of the water inlet pipe 25 is in communication with the water outlet 283, and the water outlet 283 is in communication with the condensing cavity 281, after the replenishment of the heating cavity 21a with water is completed, the controller 80 controls the heating element 22 to heat, and after the heating element 22 heats the cooling water in the heating cavity 21a for a period of time, water vapor is generated in the heating cavity 21a, and the water vapor is discharged from the exhaust pipe 24, and since part of the exhaust pipe 24 is located in the condensing cavity 281 at this time, and cooling water is carried in the condensing cavity 281 at this time, the cooling water can condense the water vapor flowing through the condensing cavity 281 and in the exhaust pipe 24, so as to greatly reduce the amount of water vapor sprayed from the faucet 2.

[0056] It should be noted that the cooling water last stored in the condensing cavity 281 will flow into the heating cavity 21a through the water outlet 283 and the water inlet pipe 25 when the heating cavity 21a is replenished with water next time, so as to replace the cooling water in the condensing cavity 281, thereby ensuring the persistence of the condensing effect of the condensing cavity 281.

[0057] In some embodiments, the water inlet 282 and the water outlet 283 are located on the same side or different sides of the condensing tube 28 in the width direction of the condensing tube 28, and the height of the water outlet 283 is higher than the height of the water inlet 282 in the height direction of the condensing tube 28. It can be understood that the position of the water outlet 283 on the condensing tube 28 in the height direction of the condensing tube 28 needs to be higher than the position of the water inlet 282, so that part of the cooling water entering from the water inlet 282 can remain in the condensing cavity 281, thereby facilitating the partial immersion of the exhaust pipe 24 in the cooling water, thereby improving the condensing effect of the condensing tube 28.

[0058] It should be noted that the height of the position of the water inlet 282 on the condensing tube 28 to the position of the water outlet 283 in the height direction of the condensing tube 28 is not specifically limited. And the width direction of the condensing tube 28 and the height direction of the condensing tube 28 are perpendicular to each other.

[0059] In other embodiments, the water inlet 282 is arranged at the bottom of the condensing tube 28 and the water outlet 283 is arranged at the top of the condensing tube 28 in the height direction of the condensing tube 28. It can be understood that the water inlet 282 can be arranged at the top of the condensing tube 28, and the water outlet 283 is arranged at the top of the condensing tube 28, so that more cooling water can remain in the condensing cavity 281, thereby facilitating the partial immersion of the exhaust pipe 24 in the cooling water, thereby improving the condensing effect of the condensing tube 28.

[0060] Please refer to Figures 7-9 In some embodiments, the height of the water inlet pipe 25 is lower than the height of the exhaust pipe 24 in the height direction of the heat tank assembly 20. It can be understood that since the exhaust pipe 24 is partially arranged in the condensing cavity 281, and the other end of the water inlet pipe 25 is communicated with the water outlet 283, the water outlet 283 is communicated with the condensing cavity 281, so by arranging the height of the water inlet pipe 25 to be lower than the height of the exhaust pipe 24, the water inlet pipe 25 is closer to the tank body 21, so that on the one hand, the water supply efficiency to the heating cavity 21a can be improved, and on the other hand, the height of the other end of the water inlet pipe 25 is lower than the end of the exhaust pipe 24 away from the tank body 21, so that when the condensing cavity 281 is filled with cooling water, the cooling water in the condensing cavity 281 will only flow into the water inlet pipe 25 from the water outlet 283, but not from the end of the exhaust pipe 24 away from the tank body 21, so as to avoid the cooling water in the condensing cavity 281 from flowing into the heating cavity 21a from the exhaust pipe 24.

[0061] It should be noted that the height direction of the heat tank assembly 20 described above can be understood as the height direction of the condensing tube 28.

[0062] Please refer to Figure 6 and Figure 8In some embodiments, the condensing pipe 28 comprises a condensing section 284 having a first condensing opening 2841 and a second condensing opening 2842. It can be understood that a condensing cavity 281 can be formed inside the condensing section 284, and the condensing cavity 281 is in communication with the first condensing opening 2841 and the second condensing opening 2842, so that the exhaust pipe 24 passes out of the second condensing opening 2842 after passing through the condensing cavity 281 from the first condensing opening 2841, so that part of the exhaust pipe 24 is located in the condensing cavity 281, thereby facilitating the condensing water in the condensing cavity 281 to condense the water vapor in the exhaust pipe 24 passing through the condensing cavity 281.

[0063] In addition, after part of the exhaust pipe 24 passes through the condensing section 284, the exhaust pipe 24 and the first condensing opening 2841 and the second condensing opening 2842 need to be sealed, on the one hand, to achieve water vapor separation, and on the other hand, to prevent the cooling water in the condensing cavity 281 from flowing out of the condensing pipe 28 from the first condensing opening 2841 or the second condensing opening 2842.

[0064] Please continue to refer to Figure 6 and Figure 8 Further, in some embodiments, the condensing pipe 28 further comprises a supporting pipe section 285, one end of the supporting pipe section 285 is connected to one end of the condensing section 284 close to the tank 21, the supporting pipe section 285 is in communication with the first condensing opening 2841, so that the exhaust pipe 24 passes through the supporting pipe section 285 and extends into the condensing cavity 281; and one end of the supporting pipe section 285 abuts against the tank 21, so as to support the condensing section 284.

[0065] Please continue to refer to Figure 6 and Figure 8 Further, in some embodiments, the condensing pipe 28 further comprises an air outlet pipe section 286, one end of the air outlet pipe section 286 is connected to one end of the condensing section 284 away from the tank 21, the other end of the air outlet pipe section 286 is in communication with the faucet 2, and the air outlet pipe section 286 is in communication with the second condensing opening 2842, so that one end of the exhaust pipe 24 away from the tank 21 extends into the air outlet pipe section 286 through the second condensing opening 2842, thereby achieving the extension of part of the exhaust pipe 24 into the air outlet pipe section 286.

[0066] It should be noted that the connection mode of the condensing section 284, the supporting pipe section 285 and the air outlet pipe section 286 is not limited in the embodiments of the present application.

[0067] Please continue to refer to Figure 6 and Figure 8Exemplarily, the condensing section 284, the supporting tube section 285 and the air outlet tube section 286 are an integral component; that is, the condensing section 284, the supporting tube section 285 and the air outlet tube section 286 can be integrally formed by one-time injection molding, so that on the one hand, the exhaust pipe 24 can be conveniently extended into the condensing pipe 28, and on the other hand, the stability and sealing performance of the connection between the condensing section 284, the supporting tube section 285 and the air outlet tube section 286 can be improved, so as to avoid the cooling water in the condensing cavity 281 from flowing out of the condensing pipe 28.

[0068] Exemplarily, the condensing section 284, the supporting tube section 285 and the air outlet tube section 286 are connected by welding, so as to realize the connection between the one end of the condensing section 284 close to the tank body 21 and the supporting tube section 285, and the connection between the other end of the condensing section 284 away from the tank body 21 and the air outlet tube section 286.

[0069] After the exhaust pipe 24 is extended into the air outlet tube section 286, in order to realize the sealed connection between the supporting tube section 285 and the air outlet tube section 286 and the part of the exhaust pipe 24, therefore, in some embodiments, the supporting tube section 285 and the air outlet tube section 286 are tightly fitted with the exhaust pipe 24; that is, the inner diameter of the supporting tube section 285 and the inner diameter of the air outlet tube section 286 are equal to the outer diameter of the exhaust pipe 24, so that the outer tube wall of the exhaust pipe 24 is respectively sealed with the inner tube wall of the supporting tube section 285 and the inner tube wall of the air outlet tube section 286, thereby improving the sealing performance of the connection between the exhaust pipe 24 and the supporting tube section 285 and the air outlet tube section 286, so as to avoid the cooling water in the condensing cavity 281 from flowing out of the condensing pipe 28, and realize water vapor separation. Of course, in other embodiments, the supporting tube section 285 and the air outlet tube section 286 can be sealed and connected with the part of the exhaust pipe 24 by a silica gel sealing element.

[0070] Please refer to Figure 10 In some embodiments, the tank body 21 comprises a tank body 211, a tank top cover 212 and a tank bottom cover 213.

[0071] Specifically, the material of the tank body 21 is usually food-grade stainless steel material, so as to ensure the safety and hygiene of the liquid. These materials have the characteristics of stable structure, high temperature resistance and rust resistance, so as to meet the use requirements of the tank body 21. The tank top cover 212 is connected with the top of the tank body 211, and the tank bottom cover 213 is connected with the bottom of the tank body 211; that is, the tank top cover 212, the tank body 211 and the tank bottom cover 213 can be connected by welding, screwing or the like, so as to realize the sealed connection of the tank top cover 212, the tank body 211 and the tank bottom cover 213, and the tank bottom cover 213, the tank body 211 and the tank top cover 212 are arranged to form a heating cavity 21a, so as to ensure the sealing performance of the heating cavity 21a.

[0072] Further, due to the effect of thermal convection, the water vapor generated in the heating process in the heating cavity 21a will naturally rise, and the embodiment of the present application sets the exhaust pipe 24 on the tank top cover 212; that is, the tank top cover 212 is provided with a first through hole 2121, the exhaust pipe 24 is connected with the tank top cover 212, and another part of the exhaust pipe 24 extends into the heating cavity 21a through the first through hole 2121, so that the exhaust pipe 24 communicates with the heating cavity 21a, so as to facilitate the water vapor generated in the heating process in the heating cavity 21a to be discharged from the exhaust pipe 24.

[0073] Furthermore, the setting of the exhaust pipe 24 on the tank top cover 212 can prevent the liquid in the heating cavity 21a from backflowing; that is, if the exhaust pipe 24 is set at the bottom of the heat tank, when the external pressure (water pressure of the water supplement) is greater than the pressure of the heating cavity 21a, water may backflow into the heating cavity 21a through the exhaust pipe 24, causing pollution and damage to the heating cavity 21a.

[0074] Please continue to refer to Figure 10 In some embodiments, in order to ensure the normal operation of the heat tank assembly 20 and the safe heating of the liquid in the heating cavity 21a, the heat tank assembly 20 further comprises a detection assembly 23, which comprises a water level detection element 232, a water quality detection element, and a temperature control element 237.

[0075] Specifically, the water level detection element 232 is connected with the tank body 21 and communicates with the heating cavity 21a, so that the water level detection element 232 can detect the water level condition in the heating cavity 21a. The type of the water level detection element 232 is not specifically limited in the embodiment of the present application. For example, the water level detection element 232 can be one of a floating ball type water level sensor, an electrode type water level sensor, and a capacitive type water level sensor. The floating ball type water level sensor detects the change of the water level by the up and down floating of the floating ball. When the water level rises, the floating ball also rises; when the water level falls, the floating ball falls. The floating of the floating ball triggers the switch inside the floating ball type water level sensor, thereby outputting a corresponding electrical signal to the controller 80, so as to detect the water level condition in the heating cavity 21a. The electrode type water level sensor detects the water level by setting electrodes in the heating cavity 21a and using the conductivity of water. When the water level rises and contacts the electrodes, the circuit is turned on, thereby outputting an electrical signal to the controller 80, so as to detect the water level condition in the heating cavity 21a. The capacitive type water level sensor detects the water level by measuring the capacitance value formed between the sensor and the water level. When the water level rises, the capacitance value changes, thereby outputting a corresponding electrical signal to the controller 80, so as to detect the water level condition in the heating cavity 21a.

[0076] Please continue to refer to Figure 10Further, in some embodiments, the water level detecting element 232 comprises a high water level probe 233 and a low water level probe 234. It can be understood that the high water level probe 233 is used to detect the position of the highest water level in the heating cavity 21a, and the low water level probe 234 is used to detect the position of the lowest water level in the heating cavity 21a; that is, when the liquid in the heating cavity 21a rises to the highest water level, the water inlet pipe 25 stops supplying water to the heating cavity 21a to prevent the liquid in the heating cavity 21a from overflowing; when the liquid in the heating cavity 21a drops to the lowest water level, the water inlet pipe 25 supplies water to the heating cavity 21a to prevent the heating cavity 21a from being dry-burned.

[0077] It should be noted that the embodiments of the present application do not specifically limit the positions of the high water level probe 233 and the low water level probe 234 on the tank body 21.

[0078] Please continue to refer to Figure 10 In another embodiment, the water level detecting element 232 can comprise two high water level probes 233 and one low water level probe 234, wherein the two high water level probes 233 can be arranged on the tank top cover 212, and the positions of the high water levels detected by the two high water level probes 233 are inconsistent; that is, the heating cavity 21a has a first high water level position and a second high water level position, and in the height direction of the tank body 21, the first high water level position is higher than the second high water level position, at this time, one high water level probe 233 is used to detect the first high water level position, and the other high water level probe 233 is used to detect the second high water level position, when the other high water level probe 233 fails, the detection can still be performed through one high water level probe 233 to improve the accuracy of the detection of the high water level probe 233. Furthermore, the low water level probe 234 can be arranged on the tank top cover 212 or on the tank bottom cover 213 to detect the position of the lowest water level in the heating cavity 21a.

[0079] The water quality detecting element is connected with the tank body 21 and communicates with the heating cavity 21a; that is, the water quality detecting element is used to detect the quality of the liquid in the heating cavity 21a to ensure that the user is provided with safe and healthy liquid. The embodiments of the present application do not specifically limit the type of the water quality detecting element, and exemplarily, the water quality detecting element can be an electrochemical sensor, a biological sensor, etc.

[0080] The temperature control element 237 is connected with the tank body 21 and communicates with the heating cavity 21a; that is, part of the temperature control element 237 extends into the heating cavity 21a so that the temperature control element 237 detects the temperature of the liquid in the heating cavity 21a. The temperature control element 237 can be arranged on the tank top cover 212 or on the upper part of the tank body 211, and the embodiments of the present application do not specifically limit this.

[0081] Please continue to refer to Figure 10Further, in some embodiments, the temperature control element 237 comprises a temperature control fixing plate 2371 and a temperature sensor 2372. Specifically, the temperature control fixing plate 2371 is connected with the tank body 21; that is, when the temperature control element 237 is installed on the tank body 211, the temperature control fixing plate 2371 can be fixed on the tank body 211 or the tank top cover 212 or the tank bottom cover 213 by welding, screwing, clamping, bonding or the like. The temperature control fixing plate 2371 is provided with a second through hole 2373 in communication with the heating cavity 21a, so that the temperature sensor 2372 can extend into the heating cavity 21a through the second through hole 2373, so that the temperature sensor 2372 detects the temperature of the liquid in the heating cavity 21a, and when the temperature of the liquid is too high, the controller 80 can control the heating element 22 to stop heating, so as to protect the tank 21.

[0082] Please continue to refer to Figure 10 In some embodiments, the net heat all-in-one machine 1 further comprises a water outlet assembly 90.

[0083] Specifically, the water outlet assembly 90 is installed on the shell assembly 10 and connected with the water pump 30, and the shell assembly 10 protects the water outlet assembly 90; under the action of the water pump 30, the liquid in the heating cavity 21a is pumped to the water outlet assembly 90. It can be understood that the working principle of the water pump 30 is based on the conversion of negative pressure and pressure and the driving of the motor; that is, when the user needs to take hot water, the controller 80 controls the motor of the water pump 30 to work, and the motor drives the piston or impeller in the water pump 30 to rotate to form a negative pressure in the pump cavity, which makes the liquid in the heating cavity 21a be sucked into the pump cavity; and with the continuous rotation of the piston or impeller, the liquid in the pump cavity is compressed and generates pressure, which pushes the water flow to the water outlet assembly 90; and the water outlet assembly 90 is in communication with the faucet 2, so the liquid pumped by pressure is delivered to the faucet 2 through the water outlet assembly 90, and the faucet 2 is opened for the user to take hot water.

[0084] Please refer to Figure 1 Further, the shell assembly 10 has an air outlet interface 104 and a hot water interface 105, wherein the end of the condensing pipe 28 away from the tank body 21 is in communication with the air outlet interface 104, and the water outlet assembly 90 is in communication with the hot water interface 105, so that the faucet 2 can be in communication with the air outlet interface 104 and the hot water interface 105 through the pipeline, so as to realize the communication of the faucet 2 with the condensing pipe 28 and the water outlet assembly 29, so that water vapor and hot water can flow out of the faucet 2.

[0085] In addition, the net heat all-in-one machine 1 of the present application can also realize the function of the user obtaining water at a set temperature; that is, the user can also obtain water at a temperature between normal temperature water and hot water discharged by the hot tank assembly 20 from the faucet 2.

[0086] Specifically, the net heat all-in-one machine 1 of the embodiment further comprises a first temperature sensor and a second temperature sensor; the filtering assembly 50 further comprises a pure water outlet pipe, one end of which is connected with the second filter element 53, and the other end has two branches, one of which delivers pure water into the heating cavity 21a, and the other directly delivers pure water to the faucet 2 and meets the water outlet assembly 90 at the faucet 2.

[0087] The booster pump 54 is connected with the pure water outlet pipe and outputs different pure water flow rates by adjusting its duty cycle to control the operation power, which can be determined by the warm water level selected by the user.

[0088] The faucet 2 is used as a water terminal to receive pure water from the pure water outlet pipe and hot water from the water outlet assembly 90, and to mix them to form warm water of a set temperature.

[0089] The first temperature sensor can be installed on the tank 21 or the water outlet assembly 90 to monitor the temperature of the hot water in the heating cavity 20a and feed back the data to the controller 80.

[0090] The second temperature sensor is installed on the pure water outlet pipe to detect the temperature of the pure water in the pure water outlet pipe and feed back the data to the controller 80.

[0091] The controller 80 is used to receive the data of the first temperature sensor and the second temperature sensor, and based on the temperature data, to control the operation power of the water pump 30 and the booster pump 54, so as to adjust the flow rates of the hot water and the pure water, and finally to form water of a temperature value set by the user at the faucet 2. In the embodiment, the controller 80 controls the operation power of the water pump 30 and the booster pump 54 by controlling the duty cycle thereof.

[0092] For example, the user selects a specific warm water level on the operation interface of the net heat all-in-one machine 1 according to the demand for water temperature, such as a common 45℃ or 55℃, etc.

[0093] When the user selects a warm water level, the controller 80 controls the duty cycle of the booster pump 54 according to a preset corresponding relationship. For example, when the user selects a 45℃ warm water level, the duty cycle of the booster pump 54 is set to 85%; if the user selects a 55℃ warm water level, the duty cycle of the booster pump 54 is set to 75%. By adjusting the duty cycle, the booster pump 54 can deliver pure water to the faucet 2 at a corresponding flow rate. The adjustment of the duty cycle actually controls the working time ratio of the booster pump 54, and thus controls the flow rate of the pure water, to ensure that there is a suitable amount of low-temperature pure water participating in the mixing process.

[0094] When the booster pump 54 starts to deliver pure water, the first temperature sensor continues to monitor the temperature of the hot water in the heating cavity 20a, and the second temperature sensor synchronously detects the temperature of the pure water in the pure water outlet pipe. The two temperature sensors obtain temperature data in real time and transmit the data to the controller 80, so as to provide temperature data for subsequent calculation and control of the duty cycle of the water pump 30.

[0095] After receiving the detected values of the pure water temperature and the hot water temperature, the controller 80 calculates the required duty cycle of the water pump 30 according to the internal preset control algorithm. According to the calculated duty cycle of the water pump 30, the controller 80 controls the water pump 30 to deliver hot water to the faucet 2 at a corresponding hot water flow rate. In this way, the flow rate of the hot water can be matched with the determined flow rate of the pure water, so that the mixed water at the faucet 2 reaches the user-set temperature.

[0096] The pure water delivered from the pure water outlet pipe and the hot water delivered from the water outlet assembly 80 meet and mix at the faucet. Due to the adjustment of the flow rates of the pure water and the hot water by controlling the duty cycles of the booster pump 54 and the water pump 30 in the previous steps, the mixed water can reach the set temperature according to the heat transfer and mixing principle. For example, at the 45℃ warm water level, the pure water with a suitable flow rate and the hot water with a corresponding flow rate are mixed, and finally the warm water with a temperature of 45℃ is stably output at the faucet 2, thereby meeting the user's demand.
