[0054] 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 examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0055] With the continuous development of science and technology, a water purification and heating integrated machine emerges as the times require. As known, the water purification and heating integrated machine can be directly used for drinking, and has the functions of hot water and normal temperature water outlet. The direct drinking machine with the function of hot water outlet necessarily needs a liquid level detection device to detect the height of the water level in the container, so as to know the water level state in the container at any time, and has a water supplement hole to supplement water in the tank when the water level is too low, so as to prevent the heating element from being dry-burned and damage the water purification and heating integrated machine.

[0056] However, in the related art, the water supplement hole and the water level detection element are both arranged on the tank top cover, which causes the water to flow along the tank top cover to the water level detection element under the influence of the wall attachment effect, so that the water film series phenomenon occurs, resulting in the failure of the water level detection element.

[0057] Based on this, the embodiments of the present application provide a hot tank assembly and a water purification and heating integrated machine, aiming to improve the detection accuracy of the water level detection element.

[0058] Please refer to Figures 1-2 The embodiments of the present application provide a hot tank assembly 20, which comprises a tank body 21, a heating element 22, a water level detection element 23 and a protruding part 26. The shape of the tank body 21 is various, which can be cylindrical, square or other shapes, which is not specifically limited here. The tank body 21 can be made of metal material or relatively 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 specifically limited here.

[0059] Referring to Figure 3 The tank body 21 has a heating cavity 214. The heating cavity 214 can have various shapes, such as a cylindrical shape, a square shape, or other shapes. Preferably, the tank body 21 has the same shape as 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.

[0060] Referring to Figure 2 The tank body 21 includes a tank body 211 and a tank top cover 212 connected to the top end of the tank body 211. It can be understood that the tank body 211 and the tank top cover 212 are sealingly connected. The tank body 211 and the tank top cover 212 can be connected by welding, or can be connected by adhesion, without specific limitation.

[0061] Referring to 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 user's demand for directly drinking hot water. The heating element 22 can be a graphite heating element, a tubular heating element, or a screen-printed metal ceramic track, without specific limitation. The tank body 21 usually includes a tank bottom cover 213 connected to the bottom end of the tank body 211. The heating element 22 can be installed in the tank body 211, or can be installed in the tank top cover 212, or can be installed in the tank bottom cover 213, without specific limitation. The heating element 22 can be installed in the tank body 21 by welding, or can be installed in the tank body 21 by screw connection, or can be installed in the tank body 21 by other means, without specific limitation. 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.

[0062] Referring to Figure 3 The water level detection element 23 is insulated and installed in the tank top cover 212, 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 water level detection element 23 can be directly welded to the tank top cover 212 by providing an insulating layer on the surface, or can be installed in the tank top cover 212 by threading the insulating part and the tank top cover 212, without specific limitation.

[0063] Referring to Figure 4The protruding portion 26 is arranged on the surface of the heating cavity 214 of the tank top cover 212 and partially extends into the heating cavity 214, and the water replenishing hole 261 is arranged through the protruding portion 26. It can be understood that the protruding portion 26 is arranged on the upper cavity wall of the heating cavity 214. The protruding portion 26 can be formed in various ways. The protruding portion 26 can be formed by the tank top cover 212 itself, or the protruding portion 26 can be formed by the part of the water replenishing pipe 27 extending into the heating cavity 214 through the tank top cover 212, which is not limited here.

[0064] The technical solution of the present application can separate the water replenishing hole 261 and the surface of the heating cavity 214 of the tank top cover 212 in the axial direction of the tank body 211 by arranging the protruding portion 26, so as to avoid the water film series of the water and the water level detection element 23 when the hot tank assembly 20 replenishes water through the water replenishing hole 261, thereby improving the detection accuracy of the water level detection element 23.

[0065] Please refer to Figure 4 In some embodiments of the present application, the tank top cover 212 is arranged with a avoiding hole 2121, and the hot tank assembly 20 further comprises a water replenishing pipe 27, which extends into the heating cavity 214 to form the protruding portion 26, and the water outlet of the water replenishing pipe 27 forms the water replenishing hole 261. In this way, only the water replenishing pipe 27 needs to pass through the avoiding hole 2121 and extend partially into the heating cavity 214, which facilitates the assembly of the hot tank assembly 20.

[0066] Further, please refer to Figure 4 The avoiding hole 2121 is arranged with a convex ring portion 2122 towards the surface of the heating cavity 214, the convex ring portion 2122 is arranged around the avoiding hole 2121, and the water replenishing pipe 27 extends into the heating cavity 214 through the convex ring portion 2122. In this way, the convex ring portion 2122 can guide the water replenishing pipe 27, so as to avoid the water replenishing pipe 27 being inclined when passing through the avoiding hole 2121, which causes the water replenishing hole 261 to be directed towards the water level detection element 23 and causes the water level detection element 23 to fail.

[0067] Specifically, please refer to Figure 4 The diameter of the avoiding hole 2121 gradually decreases from the direction close to the heating cavity 214, and the water replenishing pipe 27 extends into the heating cavity 214 through the avoiding hole 2121. In this way, the avoiding hole 2121 can guide the water replenishing pipe 27, which facilitates the water replenishing pipe 27 to extend into the heating cavity 214 through the avoiding hole 2121.

[0068] Please refer to Figure 5In another embodiment of the present application, the tank top cover 212 is protruded to form a protrusion 26, and the hot tank assembly 20 further comprises a water replenishing pipe 27, the water replenishing pipe 27 extends into the protrusion 26, and the water outlet of the water replenishing pipe 27 is located in the protrusion 26. In this way, the water replenishing pipe 27 only needs to extend into the protrusion 26, and the orientation of the water outlet of the water replenishing pipe 27 does not need to be considered, thereby facilitating the assembly of the hot tank assembly 20.

[0069] Please refer to 4 to Figure 5 In some embodiments of the present application, the distance h between the water replenishing hole 261 and the tank top cover 212 is greater than or equal to 3 mm. In this way, the water in the hot tank assembly 20 is effectively prevented from flowing along the outer circumferential wall of the protrusion 26 to the surface of the tank top cover 212 under the influence of the wall attachment effect, thereby further preventing the water film from being in series with the water level detection element 23 to cause the water level detection element 23 to fail.

[0070] Please refer to 3 and Figure 6 In some embodiments of the present application, the tank top cover 212 is provided with a mounting hole 215, the water level detection element 23 comprises a probe 231 and an insulating mounting seat 232, the probe 231 partially extends into the heating cavity 214, the insulating mounting seat 232 is sleeved on the probe 231, and the insulating mounting seat 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, and the hot tank assembly 20 further comprises a nut 24, the nut 24 is mounted on the threaded section 2322, and the clamping section 2321 is located on both sides of the mounting hole 215, so as to insulate the probe 231 and mount it on the tank body 21.

[0071] In this way, the probe 231 is used to detect the water level information in the heating cavity 214, and the probe 231 can be used for long-time work in a high-temperature environment. During the installation of the hot tank assembly 20, the threaded section 2322 is first passed through the mounting hole 215, and then the nut 24 is mounted on 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 insulatively mounted on the tank body 21 through the cooperation of the nut 24 and the threaded section 2322, thereby facilitating the assembly of the hot tank assembly 20, and the water is usually located at the bottom end of the tank body 211, and the mounting hole 215 is arranged on the tank top cover 212, which can effectively prevent the water from flowing out from the gap of the mounting hole 215.

[0072] It can be understood that the outer periphery of the threaded segment 2322 is provided with external threads, the threaded segment 2322 can be completely provided with external threads, the threaded segment 2322 can be only partially provided with external threads, as long as the threaded segment 2322 is provided with external threads at one end away from the clamping segment 2321 and penetrating the mounting hole 215, which is not specifically limited herein. The insulating mounting seat 232 can be made of various materials, and the insulating mounting seat 232 can be made of rubber material or plastic material, as long as it is an insulating material, which is not specifically limited herein. The internal threads of the nut 24 are matched with the external threads of the threaded segment 2322, and the nut 24 clamps the tank body 21 together with the clamping segment 2321 when the nut 24 is screwed to the final position, so as to insulate the probe 231 and install it on the tank body 21. The nut 24 can be made of various materials, and the nut 24 can be made of metal material or insulating material, which is not specifically limited herein.

[0073] It should be noted that the clamping segment 2321 can be located in the heating cavity 214, at this time, the threaded segment 2322 penetrates the mounting hole 215 and extends out of the heating cavity 214, and the nut 24 is installed at one end of the threaded segment 2322 extending out of the heating cavity 214. The clamping segment 2321 can also be located outside the heating cavity 214, at this time, the threaded segment 2322 penetrates the mounting hole 215 and extends into the heating cavity 214, and the nut 24 is installed at one end of the threaded segment 2322 extending into the heating cavity 214. Preferably, the clamping segment 2321 is located in the heating cavity 214, the threaded segment 2322 extends out of the mounting hole 215, and the nut 24 is installed at one end of the threaded segment 2322 extending out of the heating cavity 214, so that the nut 24 is located outside the heating cavity 214, thereby avoiding the influence of the nut 24 on the water in the heating cavity 214, and at the same time, the nut 24 located outside the heating cavity 214 can provide more installation space for the connection of the nut 24 and the threaded segment 2322, facilitating the assembly of the hot tank assembly 20.

[0074] Further, please refer to Figure 6 The water level detection element 23 further comprises a sealing ring 25, which is sleeved on the threaded segment 2322 and located between the nut 24 and the clamping segment 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, so as to avoid the water in the hot tank from flowing out of the mounting hole 215.

[0075] It should be noted that the sealing ring 25 can be located between the clamping segment 2321 and the tank body 21, or between the nut 24 and the tank body 21, which is not specifically limited herein. The sealing ring 25 can be made of various materials, and the sealing ring 25 can be made of, for example, nitrile rubber material or chloroprene rubber, which is not specifically limited herein.

[0076] Please refer toFigure 2 In some embodiments of the present application, the number of water level detecting elements 23 is two, the number of mounting holes 215 is two, the two mounting holes 215 are spaced apart, and the two water level detecting elements 23 are respectively mounted in the two mounting holes 215. It can be understood that the two water level detecting elements 23 are separated by the two spaced apart mounting holes 215. In this way, the two water level detecting elements 23 are arranged independently of each other, so that the phenomenon of water film channeling between the two water level detecting elements 23 can be effectively avoided, thereby preventing the water level detecting elements 23 from failing.

[0077] Specifically, referring to Figure 2 , the two water level detecting elements 23 are respectively a high water level detecting element 23a and a low water level detecting element 23b, and the low water level detecting element 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 detecting element 23a, and the lowest water level of the cover body can be detected by the low water level detecting element 23b. Since the high water level detecting element 23a and the low water level detecting element 23b are both mounted on the tank top cover 212, the length of the probe 231 of the low water level detecting element 23b is longer than the length of the probe 231 of the high water level probe 231. This makes it easy for the probe 231 of the low water level detecting element 23b to have a water film channeling phenomenon with the tank body 211. Arranging the low water level detecting element 23b at the center of the tank top cover 212 can maximize the distance between the probe 231 of the low water level detecting element 23b and the tank body 211, thereby preventing the probe 231 of the low water level detecting element 23b from failing due to the water film channeling phenomenon with the tank body 211.

[0078] When the high water level detecting 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 detecting 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.

[0079] Further, referring to Figure 2The tank body 21 further comprises a tank bottom cover 213 connected to the bottom end of the tank body 211, and the heating element 22 comprises a heating pipe 221 and wire terminals 222 connected to the two ends of the heating pipe 221 respectively, the wire terminals 222 are installed on the tank body 211, and the wire terminals 222 are used for electrical connection with an external power supply. The connection part of the heating pipe 221 and the wire terminals 222 can be parallel to the tank bottom cover 213, or the connection part of the heating pipe 221 and the wire terminals 222 can be arranged at an angle with the tank bottom cover 213. Preferably, the connection part of the heating pipe 221 and the wire terminals 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, that is, the distance between the bottom of the heating pipe 221 and the tank bottom cover 213 can be designed to be the smallest, so that the water at the bottom end of the heating cavity 214 can be fully heated, thereby avoiding that the water discharged from the heating cavity 214 is unevenly heated, and further improving the user experience. It should be noted that the external power supply refers to a power supply component outside the hot tank assembly 20, for example, a circuit board of a water purifying all-in-one machine, a power supply module of the water purifying all-in-one machine, etc.

[0080] The heating pipe 221 can be a graphite heating element, a tubular heating element or a silk screen printed metal ceramic track, which is not limited here. The wire terminals 222 can be installed on the tank body 211 by welding, screw connection or other ways, which is not limited here. The two wire terminals 222 can be arranged at an interval in the axial direction of the tank body 211, at an interval in the circumferential direction of the tank body 211, or at an interval in both the axial direction and the circumferential direction of the tank body 211, which is not limited here. Preferably, the two wire terminals 222 are arranged at an interval in the axial direction of the tank body 211, and the centers of the two wire terminals 222 can be located on the same bus of the tank body 211, so as to facilitate the connection of the two wire terminals 222 with the external power supply.

[0081] Specifically, referring to Figure 3 The heating pipe 221 is arranged in a spiral along the axial direction of the tank body 211, and the end of the probe 231 of the low water level detection element 23b close to the tank bottom cover 213 is located on the inside of the heating pipe 221. In this way, the spiral arrangement of the 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 meanwhile, the probe 231 of the low water level detection element 23b extending into the inside of the heating pipe 221 can make full use of the space in the inside of the heating pipe 221.

[0082] It can be understood that, in the same setting of the tank body 21 and the heating pipe 221, when the probe 231 of the low water level detection piece 23b extends to the position between the outside of the heating pipe 221 and the tank body 211, the distance between the probe 231 of the low water level detection piece 23b and the heating tank and the tank body 211 is relatively small, and the water film channeling phenomenon is easy to occur, and when the probe 231 of the low water level detection piece 23b extends to the inside of the heating pipe 221, the distance between the probe 231 of the low water level detection piece 23b and the tank body 211 is relatively long, and the water film channeling phenomenon can be effectively avoided.

[0083] Please refer to Figure 3 In some embodiments of the present application, the heating piece 22 comprises a heating pipe 221 and a wiring terminal 222 connected to the two ends of the heating pipe 221 respectively, the wiring terminal 222 is installed on the tank body 211, and the wiring terminal 222 is used for electrical connection with an external power supply; the tank body 211 is provided with a drain port 28, and the drain port 28 is arranged to overlap with the heating pipe 221 in the radial direction of the tank body 211. In this way, the drain port 28 is close to the heating pipe 221, so that the water discharged from the drain port 28 is the water near the heating pipe 221 when the user takes water, so that the water temperature of the water discharged from the heating tank is higher, and the use experience of the user is improved.

[0084] Please refer to Figure 7 The present application also provides a pure heat all-in-one machine 1, which comprises a shell assembly 10, a filtering system 50, a control panel, a water pump 30 and the above-mentioned heating tank assembly 20, the filtering system 50, the control panel, the water pump 30 and the heating tank assembly 20 are all installed in the shell assembly 10, the filtering system 50 and the water pump 30 are all communicated with the heating cavity 214, and the control panel is electrically connected with the water pump 30, the heating piece 22 and the water level detection element 23.

[0085] The detection result of the water level detection element 23 is transmitted to the control panel in the form of an electric signal, and the control panel controls the filtering system 50 and the water pump 30 to work according to the detection result of the water level detection element 23.

[0086] In order to facilitate understanding, the number of the water level detection element 23 is two, and the two water level detection elements 23 are respectively a high water level detection piece 23a and a low water level detection piece 23b. When the high water level detection piece 23a detects that the water in the heating cavity 214 reaches the highest water level, the high water level detection piece 23a transmits an electric signal to the control panel, and the control panel controls the filtering system 50 to stop delivering purified water to the heating tank assembly 20, so as to avoid that the water in the tank body 21 is too much and damaged. When the low water level detection piece 23b detects that the water in the heating cavity 214 reaches the lowest water level, the low water level detection piece 23b transmits an electric signal to the control panel, and the control panel controls the water pump 30 to stop working and controls the filtering system 50 to deliver purified water to the heating tank assembly 20, so as to avoid that the heating piece 22 is damaged by dry burning.

[0087] 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 purification all-in-one machine 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 detection member is provided. The common water level detection member extends into the heating cavity 214 and 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 forms a loop with the common water level probe 231 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 231 through the water to generate a signal.

[0088] Please refer to Figure 7 In some embodiments of the present application, the water purification all-in-one machine 1 further comprises a waterway board 60. The waterway board 60 is provided with a plurality of connection ports and waterways 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 waterways through the corresponding connection ports. The water inlet of the tank body 21 is in communication with the waterways of the waterway board 60. 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, the number of pipelines of the water purification all-in-one machine 1 is reduced by providing the waterway board 60, thereby facilitating the assembly of the water purification all-in-one machine 1 as a whole.

[0089] 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 in the water.

[0090] The reverse osmosis filter element can be composed of one or more of cellulose acetate and polyamide. The main functions of the reverse osmosis filter element include filtering microorganisms, removing suspended solids, removing organic matter and removing heavy metals, thereby effectively purifying the water quality and ensuring the safety and hygiene of the water quality.

[0091] The post-treatment filter element can remove substances such as color, odor and odor in the water, and simultaneously adsorb macromolecular organic matter in the water. The post-treatment filter element can be a granular activated carbon filter element. The post-treatment filter element can also be a compressed activated carbon filter element, without specific limitation.

[0092] It should be noted that the net heat all-in-one machine 1 also includes a faucet, and the filter system 50 also includes 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 also connected with the faucet. The faucet is in communication with the water channel of the waterway plate 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 plate 60, so that the water entering the waterway plate 60 directly flows to the faucet after passing through the pre-treatment filter element, the reverse osmosis filter element and the post-treatment filter element, 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 plate 60 is pumped to the faucet by the water pump 30 after passing through the pre-treatment filter element, the reverse osmosis filter element, the post-treatment filter element and the heating cavity 214, thereby enabling the user to obtain hot water. In this way, the user experience is improved.

[0093] Further, please refer to Figure 7 The filter element system and the hot tank assembly 20 are respectively located on both sides of the waterway plate 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.

[0094] Please refer 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 pumps water from the heating cavity 214 to the water outlet of the net heat 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 pumps 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 pumped by the water pump 30 to move upward along the inner wall surface of the water suction port 31 under the action of buoyancy, thereby avoiding the water vapor pumped by the water pump 30 from causing air blockage and affecting the normal work of the water pump 30.

[0095] It should be noted that the inner diameter of the water suction port 31 of the water pump 30 can be linearly reduced in the water suction direction to be funnel-shaped, or the inner diameter of the water suction port 31 of the water pump 30 can be exponentially reduced in the water suction direction to be arc-shaped. Here, they will not be listed one by one.

[0096] Please refer to Figure 9In some embodiments of the present application, 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, the tank bottom cover 213 is provided with a drain port 28 communicating with the heating cavity 214, the water inlet of the water pump 30 communicates with the drain port 28, the water heating and purifying 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 pump 30, 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 in the heating cavity 214, so that the drain pipeline 70 will be affected by the hot water in the heating cavity 214 and thus has a certain amount of heat, so that the water pumped out by the water pump 30 will be heated again when passing through the drain pipeline 70, thereby avoiding that the temperature of the water pumped out by the water 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 also has a high water temperature when the user takes water for the first time, thereby improving the user experience.

[0097] 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 is not specifically limited here.

[0098] In addition, referring to Figure 3 and Figure 10 , the water heating and purifying 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, for this purpose, the water heating and purifying 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 is arranged in the heating cavity 214, for detecting the temperature of the hot water in the heating cavity 214, the second temperature sensor 1C is arranged in the pure water pipeline, for detecting the normal 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, 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 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 hot water temperature of the hot water in the water outlet pipe of the tank body 21.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.
