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 directly drink hot water, a heat tank assembly is provided in the water purifier to heat the water. Usually, the water in the heating cavity is heated by applying a large current to the heating element.

[0045] However, in the related art, the heating element and the common water level probe are both mounted on the tank body, which makes the large current on the heating element easily affect the common water level probe through the tank body, so that the common water level probe is broken down by the large current, and the water purifier cannot be used.

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

[0047] Please refer to 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 and a common water level probe 27. The shape of the tank body 21 is various, which can be cylindrical, square or other shapes, which is not limited here. The tank body 21 can be made of metal material or hard and environmentally friendly plastic, as long as it 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 refer to Figure 2 The tank body 21 comprises 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, and the tank body 211, the tank top cover 212 and the tank bottom cover 213 jointly constitute a heating cavity 214. The shape of the heating cavity 214 is various, which 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 refer to Figure 2 The heating element 22 comprises a heating pipe 221 and a connecting terminal 222 connected to both ends of the heating pipe 221, and the connecting terminal 222 is mounted on the tank body 211 and used for electrical connection with an external power supply. It should be noted that the external power supply refers to a fixed component outside the hot tank assembly 20, such as the circuit board of the water purification integrated machine, the power supply module of the water purification integrated machine, etc.

[0050] The heating tube 221 is used to heat the purified water in the heating cavity 214, so as to meet the needs of the user to directly drink hot water. The types of the heating tube 221 are various, and the heating tube 221 can be a graphite heating element, a tubular heating element, or a silk screen printed metal ceramic track, which is not specifically limited here. The wiring terminal 222 can be installed on the kettle body 211 by welding, screw connection, or other ways, which is not specifically limited here. The positions of the two wiring terminals 222 on the kettle body 211 are various, and the two wiring terminals 222 can be arranged axially, circumferentially, or both axially and circumferentially, which is not specifically limited here. Preferably, the two wiring terminals 222 are arranged axially, and the centers of the two wiring terminals 222 can be located on the same busbar of the kettle body 211, so as to facilitate the connection of the two wiring terminals 222 with the external power supply.

[0051] The connection part of the heating tube 221 and the wiring terminal 222 can be parallel to the kettle bottom cover 213, or can be arranged at an angle with the kettle bottom cover 213, preferably, please refer to Figure 3 The connection part of the heating tube 221 and the wiring terminal 222 is parallel to the kettle bottom cover 213. In this way, the bottom of the heating tube 221 can be as close to the kettle bottom cover 213 as possible, that is, the distance between the bottom of the heating tube 221 and the kettle bottom cover 213 can be designed to be the smallest, so as to sufficiently heat the water at the bottom end of the heating cavity 214, thereby avoiding the uneven heating of the water in the heating cavity 214, the hot and cold water discharged from the heating cavity 214, and the improvement of the user experience.

[0052] Please refer to Figure 3 The common water level probe 27 is insulatedly installed on the kettle bottom cover 213 and extends into the heating cavity 214. The common water level probe 27 can be directly welded on the kettle bottom cover 213 by arranging an insulation layer on the surface, or can be installed on the kettle bottom cover 213 by sleeving an insulation part and screwing the insulation part with the kettle top cover 212, which is not specifically limited here.

[0053] The wiring terminal 222 and the common water level probe 27 in the embodiments of the present application are respectively installed on the tank body 211 and the tank bottom cover 213, so that the wiring terminal 222 and the common water level probe 27 are far away from each other, and the tank body 211 and the tank bottom cover 213 are not integrally arranged, so that the current has a larger resistance when passing through the tank body 211 to the tank bottom cover 213, thereby avoiding the influence of the large current of the heating element 22 on the common water level probe 27, causing the common water level probe 27 to be broken down, and thereby prolonging the service life of the net heat all-in-one machine 1, so that the stability of the common water level probe 27 is improved.

[0054] Please refer to Figure 3 In some embodiments of the present application, the heating pipe 221 is spirally arranged along the axial direction of the tank body 211, and the end of the common water level probe 27 extending into the heating cavity 214 is located on the inside of the heating pipe 221. In this way, the spirally arranged heating pipe 221 can increase the contact area between the heating pipe 221 and the water in the heating cavity 214, thereby improving the heating efficiency of the heating element 22, and at the same time, the common water level probe 271 extending into the inside of the heating pipe 221 can make full use of the space inside the heating pipe 221.

[0055] Please refer to Figure 4 In some embodiments of the present application, the tank bottom cover 213 is provided with a mounting hole 215, the hot tank assembly 20 includes an insulating mounting seat 272 and a nut 24, the common water level probe 27 partially extends into the heating cavity 214, the insulating mounting seat 272 is sleeved on the common water level probe 27, the insulating mounting seat 272 has a clamping section 2721 and a threaded section 2722 in the axial direction of the probe 271, the threaded section 2722 passes through the mounting hole 215, the nut 24 is installed on the threaded section 2722 and is located on the two sides of the clamping section 2721 with respect to the mounting hole 215, so as to install the common water level probe 27 on the tank bottom cover 213. In this way, during the installation of the hot tank assembly 20, the threaded section 2722 is first passed through the mounting hole 215, and then the nut 24 is installed on the end of the threaded section 2722 away from the clamping section 2721 and passing through the mounting hole 215, so that the probe 271 can be insulated and mounted on the tank body 21 by cooperation of the nut 24 and the threaded section 2722, thereby facilitating the assembly of the hot tank assembly 20.

[0056] Further, please refer to Figure 4 The hot tank assembly 20 further includes a sealing ring 25, the sealing ring 25 is sleeved on the threaded section 2722 and located between the nut 24 and the clamping section 2721. 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 avoiding the water in the hot tank from flowing out of the mounting hole 215.

[0057] It should be noted that the sealing ring 25 can be located between the clamping section 2721 and the tank body 21, or 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 chloroprene rubber, which is not specifically limited here.

[0058] Please refer to Figure 4 In some embodiments of the present application, the clamping section 2721 is located in the heating cavity 214, the threaded section 2722 extends from the mounting hole 215, and the nut 24 is mounted at one end of the threaded section 2722 extending out of the heating cavity 214. It can be understood that the common water level probe 27 is insulatedly mounted on the tank body 21 through the mounting hole 215, that is, the common water level probe 27 is insulatedly mounted on the tank top cover 212. In this way, compared with mounting the nut 24 in the heating cavity 214, the threaded section 2722 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 hot tank assembly 20.

[0059] Please refer to Figure 3 In some embodiments of the present application, the hot tank assembly 20 further comprises a high water level detection member 23a and a low water level detection member 23b, both of which are mounted on the tank top cover 212 and extend into the heating cavity 214, and the high water level detection member 23a and the low water level detection member 23b are arranged in a spaced manner. In this way, the high water level detection member 23a and the low water level detection member 23b are arranged independently of each other, thereby effectively avoiding the phenomenon of water film channeling between the high water level detection member 23a and the low water level detection member 23b, which can cause the high water level detection member 23a and the low water level detection member 23b to fail. It should be noted that the high water level detection member 23a and the low water level detection member 23b constitute the water level detection element 23.

[0060] Specifically, the detection end of the high water level detection member 23a is located at the highest water level, the detection end of the low water level detection member 23b is located at the lowest water level, and the common water level probe 27 is lower than 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 and the common water level probe 27 form a loop through the water, that is, a signal is generated. When the water level is higher than the highest water level, the high water level detection member 23a and the common water level probe 27 form a loop through the water, that is, a signal is generated. When the high water level detection member 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, so as to prevent the tank body 21 from being damaged due to excessive water in the hot tank. When the low water level detection member 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, so as to prevent the heating member 22 from being damaged due to dry burning.

[0061] When the heating tube 221 is arranged along the axial direction of the tank body 211, the low water level detection member 23b is arranged at the end close to the tank bottom cover 213 and inside the heating tube 221. In this way, the low water level detection member 23b extends into the inside of the heating tube 221 and can make full use of the space inside the heating tube 221. In the same way, when the tank body 21 and the heating tube 221 are arranged, if the low water level detection member 23b extends into the position between the outside of the heating tube 221 and the tank body 211, the distance between the low water level detection member 23b and the heating tank and the tank body 211 is relatively small and the water film channeling phenomenon is likely to occur. However, when the low water level detection member 23b extends into the inside of the heating tube 221, the distance between the low water level detection member 23b and the tank body 211 is relatively large and the water film channeling phenomenon can be effectively avoided.

[0062] Further, referring to Figure 3 , the low water level detection member 23b is arranged at the center 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 member 23a and the lowest water level of the cover body can be detected by the low water level detection member 23b. Since the high water level detection member 23a and the low water level detection member 23b are both arranged on the tank top cover 212, the length of the low water level detection member 23b is longer than that of the high water level detection member 23a. This makes the low water level detection member 23b more likely to cause the water film channeling phenomenon between the low water level detection member 23b and the tank body 211. Arranging the low water level detection member 23b at the center of the tank top cover 212 can maximize the distance between the low water level detection member 23b and the tank body 211, thereby avoiding the water film channeling phenomenon between the low water level detection member 23b and the tank body 211, which can cause the low water level detection member 23b to fail.

[0063] Referring to Figure 5 , in some embodiments of the present application, the heating tank assembly 20 further comprises a water replenishing pipe 26, which is arranged on the tank top cover 212 and extends into the heating cavity 214, so that the water replenishing hole of the water replenishing pipe 26 is arranged at a distance from the surface of the heating cavity 214 of the tank top cover 212. In this way, the water replenishing hole is arranged at a distance from the surface of the heating cavity 214 of the tank top cover 212 in the axial direction of the tank body 211, thereby avoiding the water film channeling phenomenon between the water replenishing hole and the high water level detection member 23a and the low water level detection member 23b, which can cause the high water level detection member 23a and the low water level detection member 23b to fail when the heating tank assembly 20 replenishes water through the water replenishing hole.

[0064] Specifically, referring to Figure 5The water supply hole of the water supply pipe 26 is arranged at a distance h from the surface of the heating cavity 214 of the tank top cover 212, where h≥3mm. In this way, the water flowing along the outer wall of the water supply pipe 26 under the influence of the wall attachment effect is effectively prevented from reaching the surface of the tank top cover 212 when the hot tank assembly 20 is being supplied with water through the water supply hole, thereby further preventing the water film from causing the high water level detection member 23a and the low water level detection member 23b to fail due to the water film in series.

[0065] Referring to Figure 6 In some embodiments of the present application, the tank body 211 is provided with a drain 28, which is arranged to overlap the heating pipe 221 in the radial direction of the tank body 211. In this way, the drain 28 is arranged close to the heating pipe 221, so that the water discharged from the drain 28 when the user takes water is water near the heating pipe 221, so that the water temperature of the water discharged from the hot tank is higher, thereby improving the user experience.

[0066] Referring to Figure 7 The present application also provides a hot water integrated machine 1, which comprises a shell assembly 10, a filter system 50, a control panel, a water pump 30, and the hot tank assembly 20 described above. 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, and the control panel is electrically connected to the water pump 30, the terminal 222, and the common water level probe 27.

[0067] Referring to Figure 7 In some embodiments of the present application, the hot water integrated machine 1 further comprises a waterway board 60, which is provided with a plurality of connection ports and a waterway connecting the plurality of connection ports. The filter system 50 comprises a pre-treatment filter element and a reverse osmosis filter element. In some forms of arrangement, the filter system 50 can further comprise a post-treatment filter element. The pre-treatment filter element, the reverse osmosis filter element, and the post-treatment filter element are respectively installed in the corresponding connection ports and are in communication with the waterway through the corresponding connection ports. The water inlet of the tank body 21 is in communication with the waterway of the waterway board 60, and the water entering the waterway board 60 passes through the pre-treatment 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 board 60, the number of pipelines of the hot water integrated machine 1 is reduced, thereby facilitating the assembly of the hot water integrated machine 1 as a whole.

[0068] The pre-treatment 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. The pre-treatment filter element can remove visible impurities such as silt, rust, and insect eggs from the water.

[0069] The reverse osmosis filter core can be composed of one or more of cellulose acetate, polyamide, and the like. The main functions of the reverse osmosis filter core 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.

[0070] The post-processing filter core can remove substances such as color, odor, and peculiar smell in the water, and simultaneously adsorb macromolecular organic matter in the water. The post-processing filter core can be a granular activated carbon filter core, and the post-processing filter core can also be a compressed activated carbon filter core, which is not specifically limited herein.

[0071] It should be noted that the water purifying and heating all-in-one machine 1 further includes a faucet, and the filtering system 50 further includes a pure water pipeline, an outlet of the post-processing filter core 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 water channel of the waterway board 60 and the water outlet of the water pump 30. 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 water channel of the waterway board 60, so that the water entering the waterway board 60 directly flows to the faucet through the pre-processing filter core, the reverse osmosis filter core, the post-processing filter core, and the pure water pipeline, thereby enabling the user to obtain cold pure water. 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 board 60 is drawn to the faucet by the water pump 30 through the pre-processing filter core, the reverse osmosis filter core, the post-processing filter core, and the heating cavity 214, thereby enabling the user to obtain hot water. In this way, the user experience is improved.

[0072] Further, referring to Figure 7 , the filter core system and the heating 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 all-in-one machine.

[0073] Referring to Figure 8 , in some embodiments of the present application, the inner diameter of the water suction port 31 of the water pump 30 is reduced in the water suction direction. It can be understood that the water suction port 31 of the water pump 30 is in communication with the water outlet 28 on the tank body 21, and the water pump 30 draws water from the heating cavity 214 to the water outlet of the water purifying and heating all-in-one 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 pump 30 is drawing 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 enables the water vapor drawn by the water pump 30 to move upward along the inner wall surface of the water suction port 31 under the action of buoyancy during the water drawing process, thereby avoiding the water vapor drawn by the water pump 30 from causing air blockage and affecting the normal operation of the water pump 30.

[0074] It should be noted that the inner diameter of the water suction port 31 of the water suction pump 30 can be linearly reduced in the water suction direction to form a funnel shape, or can be exponentially reduced in the water suction direction to form an arc shape, which will not be listed one by one here.

[0075] Please refer to Figure 9 In some embodiments of the present application, the tank bottom cover 213 is provided with a drain port 28 communicating with the heating cavity 214, the water inlet of the water suction pump 30 communicates with the drain port 28, and the water purification and heating all-in-one machine 1 further comprises a drain pipeline 70, one end of the drain pipeline 70 communicates with the water outlet of the water suction pump 30, and the other end of the drain 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 drain pipeline 70 is partially arranged in the heating cavity 214, so that the drain pipeline 70 is affected by the hot water in the heating cavity 214 and has a certain amount of heat, so that the water sucked by the water suction pump 30 is heated again when passing through the drain pipeline 70, thereby avoiding that the temperature of the water sucked by the water suction pump 30 is too low. At the same time, when the user stops using, part of the water will accumulate in the drain pipeline 70, and the drain pipeline 70 can continuously heat the accumulated water, so that the water accumulated in the drain pipeline 70 has a high water temperature when the user takes water for the first time, thereby improving the user experience.

[0076] It can be understood that the extension direction of the part of the drain pipeline 70 in the tank body 21 can be parallel to the axial direction of the tank body 211, or can be arc-shaped, or can be spiral-shaped, which will not be specifically limited here.

[0077] In addition, please refer to Figure 3 and Figure 10 The water purification and heating all-in-one machine 1 of the present application can also realize the function of obtaining water at a set temperature for the user, 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 1A. To this end, the water purification and heating all-in-one machine 1 of the present application can further comprise a first temperature sensor 1B and a second temperature sensor 1C. The first temperature sensor 1B is connected with the tank body 21 and arranged in the heating cavity 214, and is used to detect the temperature of the hot water in the heating cavity 214. The second temperature sensor 1C is arranged in the pure water pipeline and is used to detect the temperature of the normal temperature water in the pure water pipeline. The first temperature sensor 1B and the second temperature sensor 1C are both connected with the controller, and the controller can receive the detection values of the first temperature sensor 1B and the second temperature sensor 1C, and control the operating power of the water suction pump 30 and the booster pump 55, so as to form water at a set temperature value at the faucet 1A. It can be understood that the first temperature sensor 1B can also be arranged in the water outlet pipe of the tank body 21 to detect the temperature of the hot water in the water outlet pipe of the tank body 21.

[0078] It can be understood that the operation panel can be provided with a warm water control device, and the warm water control device includes at least one of a button, a rotary knob, a touch screen and the like. A user can select a required warm water temperature by operating the warm water control device, so that the faucet 1A can discharge the warm water at the temperature selected by the user to meet the user's use demand.

[0079] In the embodiment of the application, the specific method steps are explained and described by taking 45℃ warm water and 55℃ warm water as examples.

[0080] When the user selects the warm water temperature through the warm water control device, the controller obtains a temperature selection signal of the warm water. If the temperature selection signal is a 45℃ warm water signal, the controller controls the booster pump 55 to adjust the duty ratio to 85%, and 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. The first output duty ratio of the water pump 30 is calculated according to a first preset formula, and the controller adjusts the output duty ratio of the water pump 30 according to the first output duty ratio value. At this time, the water outlet of the faucet 1A can flow out 45℃ warm water. When the controller detects that the water level of the tank 21 drops to a low water level, or the controller receives a closing signal of the faucet 1A, the controller controls the water outlet of the faucet 1A to stop discharging water.

[0081] If the temperature selection signal is not a 45℃ warm water signal, it indicates that the user selects 55℃ warm water. The controller controls the booster pump 55 to adjust the duty ratio to 75%, and 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. The second output duty ratio of the water pump 30 is calculated according to a second preset formula, and the controller adjusts the output duty ratio of the water pump 30 according to the second output duty ratio value. At this time, the water outlet of the faucet 1A can flow out 55℃ warm water. When the controller detects that the water level of the tank 21 drops to a low water level, or the controller receives a closing signal of the faucet 1A, the controller controls the water outlet of the faucet 1A to stop discharging water.

[0082] It can be understood that in other embodiments, the operation panel can also provide other warm water temperature selections, such as 35℃, 50℃ and 60℃, and the like. In the embodiment of the application, this is not specifically limited.
