DETAILED DESCRIPTION

[0043] 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 do not limit the present application.

[0044] With the continuous development of science and technology, household water purifiers have emerged as the times require. As we all know, water purifiers can be directly used for drinking, in order to meet the needs of users to drink hot water directly, a hot tank assembly is provided in the water purifier to heat the water.

[0045] However, in the related art, the water purifier is provided with a water level detection element to detect the water level in the water purifier, so that the water purifier can be replenished in time, and the water level detection element usually adopts a mechanical float ball or a liquid level float ball, wherein the mechanical float ball is mostly made of plastic, so it cannot be immersed in a solution above 70 degrees Celsius for a long time, and there is a risk of deformation, and installation will cause water level error, affecting performance; the liquid level float ball uses a reed tube process inside, which is a pure manual welding and installation, and there is an installation out-of-position phenomenon, the reed tube is a glass product, and if there is a hidden crack, it is not easy to be found, and the float is prone to failure after long-term use, affecting the detection result, at the same time, the above products are prone to collision during transportation, causing the shell to break, further affecting the use effect.

[0046] Based on this, the embodiment of the present application provides a hot tank assembly and a heat and water purification integrated machine, aiming to improve the stability of the water level detection element.

[0047] Please see Figures 1 to 2 The embodiment of the present application provides a hot tank assembly 20, which comprises a tank body 21, a heating element 22, a water level detection element 23 and a nut 24. The shape of the tank body 21 is various, and the tank body 21 can be cylindrical, square or other shapes, which are not limited here. The tank body 21 can be made of metal material or hard and environmentally friendly plastic, as long as the tank body 21 can not pollute the purified water and can withstand high temperature, which is not limited here. Of course, when the tank body 21 is made of metal material, such as stainless steel, it has the advantages of high structural strength, high temperature resistance and low cost.

[0048] Please see Figures 2 to 3 The tank body 21 has a heating cavity 214 and a mounting hole 215 communicating with the heating cavity 214. The shape of the heating cavity 214 is various, and the heating cavity 214 can be cylindrical, square or other shapes. Preferably, the shape of the tank body 21 is the same as that of the heating cavity 214, so that the thickness of the tank body 21 is uniform, and the volume of the tank body 21 is maximized.

[0049] Please see Figure 2 The heating element 22 is installed in the tank body 21 and located in the heating cavity 214. The heating element 22 is used to heat the purified water in the heating cavity 214, so as to meet the demand of users to drink hot water directly. The type of the heating element 22 is various, and the heating element 22 can be a graphite heating element, a tubular heating element or a silk screen printed metal ceramic track, which is not limited here. The tank body 21 is usually composed of a tank body 211, a tank top cover 212 and a tank bottom cover 213. The heating element 22 can be installed in the tank body 211, the tank top cover 212 or the tank bottom cover 213, which is not limited here. The heating element 22 can be installed in the tank body 21 by welding, screw connection or other ways, which is not limited here.

[0050] Please see Figures 3 to 4The water level detecting element 23 comprises a probe 231 and an insulating mounting base 232. The probe 231 partially extends into the heating cavity 214, and the insulating mounting base 232 is sleeved on the probe 231. The probe 231 is insulated mounted on the tank body 21 through the insulating mounting base 232, so as to avoid the influence of the electrical connection between the probe 231 and the tank body 21 on the detection result of the probe 231. The insulating mounting base 232 has a clamping section 2321 and a threaded section 2322 in the axial direction of the probe 231. The threaded section 2322 passes through the mounting hole 215. It can be understood that the outer periphery of the threaded section 2322 is provided with external threads. The threaded section 2322 can be completely provided with external threads, or can be only partially provided with external threads. As long as the threaded section 2322 is provided with external threads at one end thereof which is away from the clamping section 2321 and passes through the mounting hole 215, no specific limitation is made herein.

[0051] Please refer to Figure 4 The nut 24 is mounted on the threaded section 2322 and located on the two sides of the mounting hole 215 together with the clamping section 2321, so as to insulate the probe 231 on the tank body 21. The internal threads of the nut 24 are matched with the external threads of the threaded section 2322. When the nut 24 is screwed to the final position, the nut 24 and the clamping section 2321 jointly clamp the tank body 21, so as to insulate the probe 231 on the tank body 21. The nut 24 can be made of metal material, or can be made of insulating material, and no specific limitation is made herein.

[0052] It should be noted that the clamping section 2321 can be located in the heating cavity 214. At this time, the threaded section 2322 passes through the mounting hole 215 and extends out of the heating cavity 214, and the nut 24 is mounted on one end of the threaded section 2322 which extends out of the heating cavity 214. The clamping section 2321 can also be located outside the heating cavity 214. At this time, the threaded section 2322 passes through the mounting hole 215 and extends into the heating cavity 214, and the nut 24 is mounted on one end of the threaded section 2322 which extends into the heating cavity 214. Preferably, please refer to Figure 4 The clamping section 2321 is located in the heating cavity 214, the threaded section 2322 extends out of the mounting hole 215, and the nut 24 is mounted on one end of the threaded section 2322 which extends out of the heating cavity 214. In this way, the nut 24 is located outside the heating cavity 214, so as to avoid the influence of the nut 24 on the water in the heating cavity 214. At the same time, the location of the nut 24 outside the heating cavity 214 can provide more mounting space for the connection between the nut 24 and the threaded section 2322, thereby facilitating the assembly of the thermal tank assembly 20.

[0053] The technical scheme of the present application can detect the water level information in the heating cavity 214 through the probe 231, the probe 231 can be suitable for working in a high temperature environment for a long time, thereby improving the stability of the water level detection element 23, and in the installation process of the thermal tank assembly 20, the threaded section 2322 is first inserted through the mounting hole 215, and then the nut 24 is installed at the end of the threaded section 2322 away from the clamping section 2321 and passing through the mounting hole 215, so that the probe 231 can be insulated and installed on the tank body 21 through the cooperation of the nut 24 and the threaded section 2322, facilitating the assembly of the thermal tank assembly 20.

[0054] Please refer to Figure 4 In some embodiments of the present application, the water level detection element 23 further comprises a sealing ring 25, the sealing ring 25 is sleeved on the threaded section 2322 and located between the nut 24 and the clamping section 2321. In this way, after the nut 24 is tightened, the sealing ring 25 will be extruded by the nut 24 to deform and seal the gap at the mounting hole 215, thereby preventing the water in the thermal tank from flowing out of the mounting hole 215.

[0055] It should be noted that the sealing ring 25 can be located between the clamping section 2321 and the tank body 21, or the sealing ring 25 can be located between the nut 24 and the tank body 21, which is not specifically limited here. The sealing ring 25 can be made of many materials, such as nitrile rubber, or it can be made of chlorobutyl rubber, which is not specifically limited here.

[0056] Please refer to Figure 3 In some embodiments of the present application, the tank body 21 comprises a tank body 211 and a tank top cover 212 connected to the top end of the tank body 211, and the mounting hole 215 is arranged on the tank top cover 212. It can be understood that the water level detection element 23 is insulated and installed on the tank body 21 through the mounting hole 215, that is, the water level detection element 23 is insulated and installed on the tank top cover 212. In this way, water is usually located at the bottom end of the tank body 211, and the mounting hole 215 arranged on the tank top cover 212 can effectively prevent water from flowing out of the gap at the mounting hole 215, and compared with installing the nut 24 in the heating cavity 214, the threaded section 2322 extending out of the heating cavity 214 can provide more installation space for the installation of the nut 24, thereby facilitating the assembly of the thermal tank assembly 20.

[0057] Further, please refer to Figure 3, the number of water level detection elements 23 is two, the number of mounting holes 215 is two, the two mounting holes 215 are arranged at intervals, and the two water level detection elements 23 are respectively installed in the two mounting holes 215. It can be understood that the two water level detection elements 23 are separated by the two mounting holes 215 arranged at intervals. In this way, the two water level detection elements 23 are arranged independently of each other, so that the phenomenon of water film channeling between the two water level detection elements 23 can be effectively avoided, thereby preventing the water level detection elements 23 from failing.

[0058] Specifically, please refer to Figure 2 The two water level detection elements 23 are respectively a high water level detection element 23a and a low water level detection element 23b, and the low water level detection element 23b is arranged at the center position of the tank top cover 212. It can be understood that the highest water level of the tank body 21 can be detected by the high water level detection element 23a, and the lowest water level of the cover body can be detected by the low water level detection element 23b. Since the high water level detection element 23a and the low water level detection element 23b are both installed on the tank top cover 212, the length of the probe 231 of the low water level detection element 23b is longer than the length of the probe 231 of the high water level detection element 23a. This makes it easy for the probe 231 of the low water level detection element 23b to have a water film channeling phenomenon with the tank body 211. Arranging the low water level detection element 23b at the center position of the tank top cover 212 can maximize the distance between the probe 231 of the low water level detection element 23b and the tank body 211, thereby preventing the probe 231 of the low water level detection element 23b from having a water film channeling phenomenon with the tank body 211, which can cause the low water level detection element 23b to fail.

[0059] When the high water level detection element 23a detects that the water in the heating cavity 214 reaches the highest water level, the hot tank assembly 20 can stop replenishing water in the hot water cavity in time to prevent the tank body 21 from being damaged due to excessive water in the hot tank. When the low water level detection element 23b detects that the water in the heating cavity 214 reaches the lowest water level, the hot tank assembly 20 can replenish water in the heating cavity 214 in time to prevent the heating element 22 from being damaged due to dry burning.

[0060] It should be noted that the high water level detection member 23a and the low water level detection member are electrically connected with the circuit board of the water purifier 1. Usually, the high water level detection member 23a and the low water level detection member 23b form a loop with the circuit board to generate an electrical signal. For example, the tank body 21 is electrically connected with the circuit board. When the water level is higher than the lowest water level, the low water level detection member 23b forms a loop with the tank body 211 through the water to generate a signal. When the water level is higher than the highest water level, the high water level detection member 23a forms a loop with the tank body 211 through the water to generate a signal. For another example, a common water level probe 27231 is arranged. The common water level probe 27231 extends into the heating cavity 214 and is below or flush with the lowest water level. When the water level is higher than the lowest water level, the low water level detection member 23b forms a loop with the common water level probe 27231 through the water to generate a signal. When the water level is higher than the highest water level, the high water level detection member 23a forms a loop with the common water level probe 27231 through the water to generate a signal.

[0061] Further, referring to Figure 3 The tank body 21 further comprises a tank bottom cover 213 connected to the bottom end of the tank body 211. The heating member 22 comprises a heating pipe 221 and a terminal 222 connected to the two ends of the heating pipe 221, respectively. The terminal 222 is installed on the tank body 211 and is used for electrical connection with an external power source. The connection part of the heating pipe 221 and the terminal 222 can be parallel to the tank bottom cover 213. The connection part of the heating pipe 221 and the terminal 222 can also be arranged at an angle with the tank bottom cover 213. Preferably, the connection part of the heating pipe 221 and the terminal 222 is parallel to the tank bottom cover 213. In this way, the bottom of the heating pipe 221 can be as close as possible to the tank bottom cover 213, i.e., the distance between the bottom of the heating pipe 221 and the tank bottom cover 213 can be designed to be the smallest. This can sufficiently heat the water at the bottom end of the heating cavity 214, thereby avoiding uneven heating of the water in the heating cavity 214, which can cause the water discharged from the heating cavity 214 to be hot and cold alternately, and thus improve the user experience. It should be noted that the external power source refers to a fixed component outside the hot tank assembly 20, such as the circuit board of the water purifier, the power module of the water purifier, etc.

[0062] The heating tube 221 can be a graphite heating element, a tubular heating element, or a screen-printed metal ceramic track, and the installation of the terminal 222 on the body 211 can be by welding, screwing, or other means. The two terminals 222 can be spaced apart in the axial direction of the body 211, in the circumferential direction of the body 211, or in both directions, and the centers of the two terminals 222 can be on the same generatrix of the body 211.

[0063] Specifically, referring to Figure 2 The heating tube 221 is spirally arranged along the axial direction of the body 211, and the probe 231 of the low-water-level detector 23b is located inside the heating tube 221. In this way, the spirally arranged heating tube 221 can increase the contact area between the heating tube 221 and the water in the heating cavity 214, thereby improving the heating efficiency of the heating assembly 22, and the probe 231 of the low-water-level detector 23b can make full use of the space inside the heating tube 221.

[0064] It can be understood that, in the same arrangement of the body 21 and the heating tube 221, when the probe 231 of the low-water-level detector 23b is located between the heating tube 221 and the body 211, the distance between the probe 231 and the heating tank and the body 211 is relatively small, and water film channeling is likely to occur. However, when the probe 231 of the low-water-level detector 23b is located inside the heating tube 221, the distance between the probe 231 and the body 211 is relatively large, and water film channeling can be effectively avoided.

[0065] Specifically, referring to Figure 2 In some embodiments of the present application, the heating tank assembly 20 further comprises a water outlet 26, which is arranged on the surface of the bottom cover 213 forming the heating cavity 214 and partially extends into the heating cavity 214. The water outlet 26 is provided with a drain port 28 extending along the axial direction of the body 211. In this way, the water outlet 26 can be arranged close to the heating tube 221, and the water near the heating tube 221 is more stable in temperature than the water at the bottom of the heating cavity 214, thereby improving the user experience.

[0066] It should be noted that the hot tank assembly 20 also includes a drain pipe which is in communication with the water pump 30 of the water purification all-in-one machine 1. The water outlet 26 can be formed in various ways. The water outlet 26 can be formed by the tank bottom cover 213. In this case, the water inlet of the drain pipe is located in the water outlet 26. The water outlet 26 can also be formed by the end of the drain pipe which extends into the heating cavity 214 through the tank bottom cover 213. In this case, the water inlet of the drain pipe forms the water outlet 26.

[0067] Please refer to Figure 5 The present application also provides a water purification all-in-one machine 1 which includes a shell assembly 10, a filter system 50, a control panel, a water pump 30, and the above-mentioned hot tank assembly 20. The filter system 50, the control panel, the water pump 30, and the hot tank assembly 20 are all installed in the shell assembly 10. The filter system 50 and the water pump 30 are both in communication with the heating cavity 214. The control panel is electrically connected with the water pump 30, the heating element 22, and the probe 231.

[0068] The detection result of the probe 231 is transmitted to the control panel in the form of an electric signal. The control panel controls the operation of the filter system 50 and the water pump 30 according to the detection result of the probe 231.

[0069] For ease of understanding, the number of water level detection elements 23 is two. The two water level detection elements 23 are a high water level detection element 23a and a low water level detection element 23b. When the high water level detection element 23a detects that the water in the heating cavity 214 reaches the highest water level, the high water level detection element 23a transmits an electric signal to the control panel. The control panel controls the filter system 50 to stop delivering purified water to the hot tank assembly 20, thereby avoiding damage to the water in the tank body 21 due to excessive water. When the low water level detection element 23b detects that the water in the heating cavity 214 reaches the lowest water level, the low water level detection element 23b transmits an electric signal to the control panel. The control panel controls the water pump 30 to stop working and controls the filter system 50 to deliver purified water to the hot tank assembly 20, thereby avoiding damage to the heating element 22 due to dry burning.

[0070] Please refer to Figure 5In some embodiments of the present application, the net heat all-in-one machine 1 further comprises a waterway plate 60, the waterway plate 60 is internally provided with a plurality of connecting ports and a waterway connecting the plurality of connecting ports, the filtering system 50 comprises a pretreatment filter element and a reverse osmosis filter element, and in some forms of arrangement, the filtering system 50 can further comprise a post-treatment filter element, the pretreatment filter element, the reverse osmosis filter element and the post-treatment filter element are respectively installed at the corresponding connecting ports and are in communication with the waterway through the corresponding connecting ports, the water inlet of the tank body 21 is in communication with the waterway of the waterway plate 60, and the water entering the waterway plate 60 passes through the pretreatment filter element, the reverse osmosis filter element and the post-treatment filter element in sequence and enters the heating cavity 214 of the tank body 21. In this way, by arranging the waterway plate 60, the number of pipelines of the net heat all-in-one machine 1 is reduced, thereby facilitating the assembly of the net heat all-in-one machine 1 as a whole.

[0071] The pretreatment filter element can be one or more of a stainless steel filter element, a PP cotton filter, a ceramic filter, a compressed filter and an activated carbon filter, without specific limitation here. The pretreatment filter element can remove visible impurities such as silt, rust and insect eggs in water.

[0072] The reverse osmosis filter element can be composed of one or more of cellulose acetate and polyamide, and the main functions of the reverse osmosis filter element include filtering microorganisms, removing suspended solids, removing organic matter, removing heavy metals and the like, thereby effectively purifying water quality and ensuring the safety and hygiene of the water quality.

[0073] The post-treatment filter element can remove substances such as color, odor and odor in water, and simultaneously adsorb macromolecular organic matter in water. The post-treatment filter element can be a granular activated carbon filter element, and the post-treatment filter element can also be a compressed activated carbon filter element, without specific limitation here.

[0074] It should be noted that the net heat all-in-one machine 1 further comprises a faucet, the filtering system 50 further comprises a pure water pipeline, the outlet of the post-treatment filter element is connected with the pure water pipeline, and the pure water pipeline is further connected with the faucet. The faucet is in communication with the waterway of the waterway plate 60 and the water outlet of the water pump 30, and in this way, when a user needs to drink cold water, the user only needs to operate the faucet to connect the faucet with the waterway of the waterway plate 60, so that the water entering the waterway plate 60 passes through the pretreatment filter element, the reverse osmosis filter element, the post-treatment filter element and the pure water pipeline and directly flows to the faucet, thereby enabling the user to obtain cold pure water, and when the user needs to drink hot water, the user only needs to operate the faucet to connect the faucet with the water outlet of the water pump 30, so that the water entering the waterway plate 60 passes through the pretreatment filter element, the reverse osmosis filter element, the post-treatment filter element and the heating cavity 214 and is pumped to the faucet by the water pump 30, thereby enabling the user to obtain hot water, which improves the user experience.

[0075] Further, please refer to Figure 5The filter core system and the hot tank assembly 20 are respectively located on both sides of the waterway board 60. In this way, the space in the shell assembly 10 can be fully utilized, thereby reducing the overall volume of the water purifying integrated machine.

[0076] Please refer to Figure 6 In some embodiments of the present application, the inner diameter of the water suction port 31 of the water suction pump 30 is arranged to decrease in the water suction direction. It can be understood that the water suction port 31 of the water suction pump 30 is in communication with the water outlet 28 on the tank body 21, and the water suction pump 30 sucks water from the heating cavity 214 to the water outlet of the water purifying integrated machine 1. In this way, the inner diameter of the water suction port 31 near the heating cavity 214 is large, and when the water suction pump 30 sucks water, the water mainly gathers on the side of the water suction port 31 away from the heating cavity 214, and the water at the inner wall surface of the water suction port 31 is relatively flat. This makes the water vapor sucked by the water suction pump 30 move upward along the inner wall surface of the water suction port 31 under the action of buoyancy, thereby avoiding the water vapor sucked by the water suction pump 30 causing air blockage and affecting the normal work of the water suction pump 30.

[0077] It should be noted that the inner diameter of the water suction port 31 of the water suction pump 30 can be arranged to increase in the water suction direction, which can be continuous increase, gradual increase, stepwise increase, or a combination of the two, for example, while maintaining the overall increasing trend in the water suction direction, the first section is continuously gradually increased, and the other section is gradually increased. Here, they will not be listed one by one.

[0078] Please refer to Figure 7 In some embodiments of the present application, the tank body 21 includes a tank body 211, a tank top cover 212 connected to the top end of the tank body 211, and a tank bottom cover 213 connected to the bottom end of the tank body 211. The tank bottom cover 213 is provided with a water outlet 28 in communication with the heating cavity 214, and the water inlet of the water suction pump 30 is in communication with the water outlet 28. The water purifying integrated machine 1 further includes a water drainage pipeline 70, one end of the water drainage pipeline 70 is in communication with the water outlet of the water suction pump 30, and the other end of the water drainage pipeline 70 extends out of the tank top cover 212 after sequentially penetrating through the tank bottom cover 213 and the heating cavity 214. In this way, the water drainage pipeline 70 is partially in the heating cavity 214, so that the water drainage pipeline 70 will be affected by the hot water in the heating cavity 214 and thus have a certain amount of heat. Therefore, the water sucked by the water suction pump 30 will be heated again when passing through the water drainage pipeline 70, thereby avoiding the temperature of the water sucked by the water suction pump 30 being too low. At the same time, when the user stops using, part of the water will accumulate in the water drainage pipeline 70, and the water drainage pipeline 70 can continuously heat the accumulated water, so that the water accumulated in the water drainage pipeline 70 when the user first takes water also has a high water temperature. In this way, the user's experience is improved.

[0079] It is understandable that the extension direction of the portion of the drain pipe 70 inside the tank 21 can be parallel to the axial direction of the tank body 211, or it can be arc-shaped or spiral-shaped, without any specific limitation here.

[0080] In addition, please refer to the following: Figure 3 as well as Figure 8 The integrated water purifier and heater 1 of this application can also enable users to obtain a set water temperature. That is, users can obtain warm water with a temperature between room temperature water and the hot water discharged from the heating tank assembly 20 from the faucet 1A. To this end, the integrated water purifier and heater 1 of this application can further include a first temperature sensor 1B and a second temperature sensor 1C. The first temperature sensor 1B is connected to the tank 21 and is located inside the heating chamber 214 to detect the temperature of the hot water inside the heating chamber 214. The second temperature sensor 1C is located inside the pure water pipeline to detect the room temperature water temperature in the pure water pipeline. Both the first temperature sensor 1B and the second temperature sensor 1C are connected to a controller. The controller can receive the detection values ​​from the first temperature sensor 1B and the second temperature sensor 1C and control the operating power of the water pump 30 and the booster pump 55 to generate warm water at the set temperature value at the faucet 1A. It is understood that the first temperature sensor 1B can also be located in the outlet pipe of the tank 21 to detect the hot water temperature in the outlet pipe of the tank 21.

[0081] It is understandable that the control panel may be equipped with a warm water control device, which may include at least one of buttons, knobs, touch screens, etc. Users can operate the warm water control device to select the desired warm water temperature, so that the faucet 1A can discharge warm water of the selected temperature to meet the user's needs.

[0082] In this embodiment of the application, the specific method steps are explained using 45°C and 55°C warm water as examples.

[0083] When the user selects a warm water temperature through the warm water control device, the controller receives the warm water temperature selection signal. If the temperature selection signal is a 45℃ warm water signal, the controller controls the booster pump 55 to adjust its duty cycle to 85%. The controller obtains the current ambient water temperature through the first temperature sensor 1B and the current hot water temperature through the second temperature sensor 1C. The controller calculates the first output duty cycle of the pump 30 according to the first preset formula. The controller adjusts the output duty cycle of the pump 30 according to the first output duty cycle value. At this time, 45℃ warm water can flow from the outlet of the faucet 1A. When the controller detects that the water level in the tank 21 has dropped to a low level, or when the controller receives a shut-off signal from the faucet 1A, the controller controls the outlet of the faucet 1A to stop discharging water.

[0084] If the temperature selection signal is not the 45℃ hot water signal, it indicates that the user selects 55℃ hot water, the controller controls the booster pump 55 to adjust the duty ratio to 75%, the controller obtains the current normal water temperature through the first temperature sensor 1B and obtains the current hot water temperature through the second temperature sensor 1C, and the second output duty ratio of the water pump 30 is calculated according to the second preset formula, the controller adjusts the output duty ratio of the water pump 30 according to the second output duty ratio value, at this time, the water outlet of the faucet 1A can flow out 55℃ hot water; when the controller detects that the water level of the tank 21 drops to the low water level, or the controller receives the closing signal of the faucet 1A, the controller controls the water outlet of the faucet 1A to stop water.

[0085] It can be understood that in other embodiments, the operation panel can also provide other hot water temperature selections, such as 35℃, 50℃ and 60℃, etc., which are not specifically limited in the embodiments of the present application.
