[0037] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0038] Reference is made below to Figures 1-4 Describe the hot water tank module 100 and the water dispenser according to the embodiments of the present utility model.

[0039] The hot water tank module 100 according to the first aspect embodiment of the present utility model is for a water dispenser and includes: a base 50, a heating tank 10, a water pipeline assembly 17, and a water pump 30.

[0040] Refer to Figures 1-2, the base 50 is disposed on the lower side of the heating tank 10 for supporting and fixing the heating tank 10. For example, a hot tank installation groove is provided on the base 50, and the lower side of the heating tank 10 is received in the hot tank installation groove. By providing a hot tank installation groove on the base 50 and receiving the lower side of the heating tank 10 in the hot tank installation groove, the heating tank 10 can be more firmly fixed to prevent the heating tank 10 from tipping over. For example, a limiting plate is provided on the base 50. The limiting plates are multiple and arranged circumferentially along the base 50. The multiple limiting plates and the base 50 jointly define the hot tank installation groove, and the bottom of the heating tank 10 is received in the hot tank installation groove. The limiting plates extend upward in the vertical direction. By providing the limiting plates on the base 50, the base 50 can more fully limit the heating tank 10, avoid the heating tank 10 from tipping over, and ensure that the heating tank 10 can be erected and fixed.

[0041] Optionally, the base 50 is an integrally formed part. By making the base 50 integrally formed, the number of parts of the hot tank module 100 can be reduced, and the assembly difficulty of the hot tank module 100 can be lowered.

[0042] Referring to Figure 3 , the heating tank 10 is installed on the base 50 and includes a tank body and an upper cover plate 14 assembly 12. A heating cavity 11 is provided in the tank body, and the upper cover plate 14 assembly 12 covers the top of the tank body. When the hot tank stores water or heats water, the water is received in the heating cavity 11. For example, the tank body includes an outer shell and an inner shell. The inner shell defines the heating cavity 11, and the water is received in the heating cavity 11; a heat insulation layer is defined between the outer shell and the inner shell for insulating the water in the tank body to prevent the heat of the heated water from dissipating and causing the water temperature to decrease. The heat insulation layer can be an air layer or a vacuum layer or a heat insulation structure made of a heat insulation material.

[0043] Among them, the hot tank module 100 can include a heating component. The heating component is disposed on the heating tank 10. For example, the heating component can include a heating element. The heating element can be disposed in the heating tank 10 to heat the water in the heating cavity 11. The heating component can also include a heating base. The heating base is connected to the heating element and the heating base is used to connect to the control module of the water dispenser. The control module is used to control the opening and closing of the heating component. The heating base can be located outside the heating tank 10. For example, the heating base can be fixed to the bottom of the heating tank 10. When the hot tank module 100 includes the base 50, the heating tank 10 is installed on the base 50, and the heating base can be located between the bottom surface of the heating tank 10 and the base 50. The heating component

[0044] Referring to Figures 1-2, the water pipe assembly 17 is fixed to the upper cover plate 14 assembly 12 and includes a water outlet pipe 18 and a water inlet pipe 19. Both the water inlet pipe 19 and the water outlet pipe 18 are connected to the heating tank 10. Water can enter the heating tank 10 from the water inlet pipe 19 and can be discharged from the heating tank 10 through the water outlet pipe 18. For example, the water outlet pipe 18 is connected to a water outlet faucet, and the user can receive the hot water flowing out of the water outlet pipe 18 by opening the water outlet faucet. For example, the heating tank 10 includes a water inlet and a water outlet. The water inlet pipe 19 is connected to the water inlet, and water can enter the interior of the heating tank 10 through the water inlet pipe 19 and the water inlet; the water outlet is connected to the water outlet pipe 18, and water can enter the water outlet pipe 18 through the water outlet, so as to leave the heating tank 10. By fixing the water pipe assembly 17 on the upper cover plate 14 assembly 12, the water pipe assembly 17 can be relatively fixed to the upper cover plate 14 assembly 12, making the water pipe assembly 17 become a part of the hot water tank assembly, facilitating overall modularization, and thus making the disassembly and assembly of the hot water tank assembly more convenient; moreover, the space occupied by the water pipe assembly 17 can be made smaller, increasing the space utilization rate of the heating tank 10 assembly.

[0045] Optionally, a water inlet valve 20 is provided on the water inlet pipe 19. The water inlet valve 20 can control the communication or disconnection state between the water inlet pipe 19 and the heating chamber 11 to control the water supply to the heating tank 10 or stop the water supply. For example, when the water storage tank is located above the heating tank 10 and the water in the water storage tank flows into the heating chamber 11 of the heating tank 10 under its own gravity, the opening and closing of the water inlet valve 20 can be controlled to realize the control of the water supply to the heating tank 10 or stop the water supply. Among them, the water inlet valve 20 can be an electromagnetic valve, and the water inlet valve 20 can be electrically connected to the above control module, and the control module can control the opening and closing of the water inlet valve 20.

[0046] Refer to Figure 1 , the water pump 30 is installed on the base 50 and connected in series to the water outlet pipe 18. For example, the base 50 includes a water pump base 50 and a hot water tank base 50. The water pump base 50 is arranged on the lower side of the water pump 30 to support and fix the water pump 30, and the hot water tank base 50 is arranged on the lower side of the heating tank 10 to support and fix the heating pipe. The base 50 is an integrally formed part. By installing the water pump 30 on the base 50 and connecting the water pump 30 in series to the water outlet pipe 18, the water pump 30 can be fixed relative to the base 50, facilitating overall modularization, and thus making the disassembly and assembly of the hot water tank assembly more convenient; moreover, when the water pump 30 can meet the working conditions of pumping water out of the hot water tank, the space utilization rate can be improved, and the situation that the water pump 30 forms a separate module and occupies too much space can be avoided.

[0047] According to the hot water tank module 100 of the embodiments of the present utility model, by fixing the water pipeline assembly 17 to the upper cover plate 14 of the assembly 12, and installing the water pump 30 on the base 50 and connecting it in series to the water outlet pipe 18, each component can be integrated into a module, integrating the originally scattered components in the hot water tank module 100, making the structure compact, improving the space utilization rate inside the whole machine, facilitating the miniaturization of the whole machine. In addition, it is also convenient to disassemble and assemble the hot water tank module 100 as a whole, which is convenient for maintenance.

[0048] According to some embodiments of the present utility model, referring to Figure 1 , the water pump 30 is located on the outer peripheral side of the heating tank 10. By arranging the water pump 30 on the outer peripheral side of the heating tank 10, it can make it easier for the water pump 30 to be connected in series with the water outlet pipe 18; and, by arranging the water pump 30 on the outer peripheral side of the heating tank 10, making the water pump 30 closer to the heating tank 10, the water pump 30 and the heating tank 10 can form a whole module together, avoiding the water pump 30 forming a module alone and occupying too much space, and improving the space utilization rate.

[0049] According to some embodiments of the present utility model, referring to Figure 1 , the top of the water pump 30 is lower than the top of the heating tank 10. By making the top of the water pump 30 lower than the top of the heating tank 10, it can avoid the height of the water pump 30 affecting the height of the hot water tank assembly and reduce the overall height of the hot water tank assembly; by making the water level in the heating tank 10 higher than the highest surface of the impeller of the water pump 30, the working ability of the water pump 30 can be fully utilized, enabling the water pump 30 to work better, reducing energy consumption; and it can avoid the water pump 30 from sucking air.

[0050] According to some embodiments of the present utility model, referring to Figure 1 , the water level in the heating chamber 11 has a lowest water level. When the water level in the heating chamber 11 is at the lowest water level, the liquid level in the heating chamber 11 is higher than the highest position of the impeller of the water pump 30. By making the liquid level in the heating chamber 11 higher than the highest position of the impeller of the water pump 30 when the water level in the heating chamber 11 is at the lowest water level, the working ability of the water pump 30 can be fully utilized, enabling the water pump 30 to work better, reducing energy consumption; and, it can avoid the water pump 30 from sucking air.

[0051] According to some embodiments of the present utility model, the hot water tank module 100 includes a water inlet valve 20. The water inlet valve 20 is used to control the on-off between the water inlet pipe 19 and the heating chamber 11. When water needs to be replenished into the heating chamber 11, the water inlet valve 20 is opened to connect the water inlet pipe 19 and the heating chamber 11. When water does not need to be replenished into the heating chamber 11, the water inlet valve 20 is closed to cut off the water inlet pipe 19 and the heating chamber 11. If the heating chamber 11 is continuously full of water, when the user draws water, the water inlet pipe 19 continuously replenishes water, then the user may draw a mixture of normal temperature water and hot water, which cannot meet the user's demand for high-temperature water. By making the heat pipe module include the water inlet valve 20, the hot water tank module 100 can control the water volume stored in the heating chamber 11, avoiding water boiling and overflowing; it can also control the water replenishing time in the heating chamber 11. For example, when the user draws water, the water inlet valve 20 is closed, so that the water obtained by the user can meet the temperature requirement.

[0052] According to some embodiments of the present utility model, the hot water tank module 100 includes a water outlet valve 21. The water outlet valve 21 is used to control the on-off between the water outlet pipe 18 and the heating chamber 11. When water needs to be discharged, the water outlet valve 21 can be controlled to open to connect the water outlet pipe 18 and the heating chamber 11. When water does not need to be discharged, the water outlet valve 21 can be controlled to close to cut off the water outlet pipe 18 and the heating chamber 11. By making the hot water tank module 100 include the water outlet valve 21, water can be discharged when the user needs it and closed when the user does not need it. Among them, the water outlet valve 21 can be a solenoid valve, and the water outlet valve 21 can be electrically connected to the above control module, and the control module can control the opening and closing of the water outlet valve 21.

[0053] For example, when the water outlet valve 21 is a solenoid valve, it can be judged whether the water outlet valve 21 is open according to whether the solenoid valve is energized, so as to obtain information on whether the user is drawing hot water, and then control the opening and closing of the water inlet valve 20. For example, when the user draws hot water, the water outlet valve 21 is opened. At this time, the water inlet valve 20 can be controlled to close to ensure that the water obtained by the user can meet the temperature requirement. When the user does not draw hot water, the water outlet valve 21 is closed, and when water needs to be replenished, the water inlet valve 20 can be controlled to open to ensure that there is enough water stored in the heating tank 10.

[0054] According to some embodiments of the present utility model, refer to Figures 3-4, the hot water tank module 100 further includes a water level detection component 40. The water level detection component 40 is installed on the upper cover plate 14 of the assembly 12, and the water level detection component 40 is used to detect the water level in the heating chamber 11. By including the water level detection component 40 in the hot water tank module 100, the water level in the heating chamber 11 can be monitored and controlled. For example, the water level detection component 40 is electrically connected to the water inlet valve 20. When the water level detection component 40 detects that the water level in the heating chamber 11 is too high, the water inlet valve 20 is controlled to close to stop the water inlet, so as to control the water level in the heating chamber 11 from being too high and prevent the water in the heating chamber 11 from overflowing and spraying out, causing injury to the user; when the water level detection component 40 detects that the water level in the heating chamber 11 is too low, the water inlet valve 20 is controlled to open to start water replenishment, preventing the water level in the heating chamber 11 from being lower than the impeller of the water pump 30, so that the water pump 30 pumps air.

[0055] For example, both the water level detection component 40 and the water inlet valve 20 are electrically connected to the control module, so that the electrical connection between the water level detection component 40 and the water inlet valve 20 can be realized. Since the water level detection component 40 is electrically connected to the water inlet valve 20, when the water level in the heating chamber 11 is detected to reach the highest water level, the water inlet valve 20 is closed to cut off the water inlet pipe 19 and the heating chamber 11.

[0056] At least a part of the water level detection component 40 is located in the heating chamber 11. For example, the water level detection component 40 includes a water level probe 41. By directly contacting the water with the water level probe 41, the water level in the heating chamber 11 is detected. By making at least a part of the water level detection component 40 located in the heating chamber 11, the water level detection component 40 can directly detect the water level in the heating chamber 11, and the detected data is more accurate.

[0057] According to some embodiments of the present invention, refer to Figure 3 , the water level detection component 40 is detachably installed on the upper cover plate 14 of the assembly 12. For example, the water level detection component 40 is installed on the upper cover plate 14 of the assembly 12 through fasteners such as screws. By making the water level detection component 40 detachably installed on the upper cover plate 14 of the assembly 12, the disassembly and replacement of the water level detection component 40 can be made more convenient, and the maintenance difficulty of the water level detection component 40 can be reduced.

[0058] According to some embodiments of the present invention, refer to Figure 3 , an installation hole 13 is formed on the upper cover plate 14 of the assembly 12, and the water level detection component 40 passes through the installation hole 13. By providing the installation hole 13 on the upper cover plate 14 of the assembly 12 and making the water level detection component 40 pass through the installation hole 13, the water level detection component 40 can be limited in the left-right and front-back directions relative to the upper cover plate 14, preventing the water level detection component 40 from moving and rotating, resulting in interference between the water level detection component 40 and other components and causing damage to the water level detection component 40, and the service life of the water level detection component 40 can be extended.

[0059] According to some embodiments of the present invention, the water level detection component 40 is adapted to be installed on the upper cover plate 14 assembly 12 from top to bottom and is adapted to be removed from the upper cover plate 14 assembly 12 from bottom to top. By enabling the water level detection component 40 to be installed on the upper cover plate 14 assembly 12 from top to bottom and removed from the upper cover plate 14 assembly 12 from bottom to top, the upper cover plate 14 assembly 12 can limit the water level detection component 40 upward, preventing the water level detection component 40 from falling into the heating chamber 11 and losing the function of detecting the water level; and, the water level detection component 40 can be disassembled from the upper cover plate 14, making the disassembly and replacement of the water level detection component 40 more convenient and reducing the maintenance difficulty of the water level detection component 40.

[0060] According to some embodiments of the present invention, with reference to Figure 4 , the water level detection component 40 includes a mounting seat 45 and a plurality of water level probes 41. The plurality of water level probes 41 are arranged on the mounting seat 45, and the mounting seat 45 is fixed to the upper cover plate 14 assembly 12. By mounting the water level probes 41 on the mounting seat 45 and fixing the mounting seat 45 to the upper cover plate 14 assembly 12, the water level probes 41 can be fixed relative to the upper cover plate 14 assembly 12, ensuring that the data read by the water level probes 41 is more accurate; and, it can prevent the water level probes 41 from moving or rotating, resulting in interference between the water level detection component 40 and other components and damaging the water level detection component 40, and can extend the service life of the water level detection component 40.

[0061] The water level probes 41 can be a plurality of spaced-apart ones. For example, the water level in the heating chamber 11 has a lowest water level and a highest water level. The water level probes 41 include a common probe 42, a high water level probe 4341, and a low water level probe 4441. The high water level probe 4341 is used to cooperate with the common probe 42 to detect whether the water in the heating chamber 11 exceeds the highest water level; the low water level probe 4441 is used to cooperate with the common probe 42 to detect whether the water in the heating chamber 11 is lower than the lowest water level. The common probe 42 is used in combination with the high water level probe 4341 and the low water level probe 4441 to detect the water level in the heating chamber 11.

[0062] For example, the water level probes 41 can include a plurality of high water level probes 4341, and two high water level probes 4341 are spaced apart. By enabling the water level probes 41 to include two high water level probes 4341, when one of the high water level probes 4341 is damaged, the other can still work normally, ensuring the operation of the high water level probes 4341, thereby ensuring that the water in the heating chamber 11 is lower than the highest water level and preventing the water in the heating chamber 11 from being too full and boiling, resulting in excessive pressure in the chamber, rupture, and leakage, causing danger.

[0063] According to some embodiments of the present invention, the hot water tank module 100 includes a water inlet valve 20, and the water inlet valve 20 is used to control the on-off between the water inlet pipe 19 and the heating chamber 11.

[0064] If the heating chamber 11 remains in a full water state continuously, when the user draws water, the water inlet pipe 19 replenishes water continuously, then the user may draw a mixture of normal temperature water and hot water, which cannot meet the user's demand for high-temperature water. By making the heat pipe module include a water inlet valve 20, the hot water tank module 100 can control the water volume stored in the heating chamber 11, avoiding water boiling over; it can also control the water replenishing time in the heating chamber 11. For example, when the user draws water, the water inlet valve 20 is closed, so that the water obtained by the user can meet the temperature requirement.

[0065] Wherein, the water level detection component 40 is used to open the water inlet valve 20 to connect the water inlet pipe 19 and the heating chamber 11 when detecting that the water level in the heating chamber 11 is lower than the lowest water level. By opening the water inlet valve 20 to connect the water inlet pipe 19 and the heating chamber 11 when the water level in the heating chamber 11 is lower than the lowest water level, the heating chamber 11 can have sufficient water to meet the user's water consumption requirement; and it can prevent dry burning due to no water in the heating chamber 11, which may cause the heating tank 10 to continuously heat up and lead to danger; in addition, it can also avoid the water pump 30 from pumping air.

[0066] According to some embodiments of the present invention, the hot water tank module 100 includes a water inlet valve 20. The water inlet valve 20 is used to control the on-off between the water inlet pipe 19 and the heating chamber 11. The water level detection component 40 is electrically connected to the water inlet valve 20. For example, both the water level detection component 40 and the water inlet valve 20 are electrically connected to the above control module, so as to realize the electrical connection between the water level detection component 40 and the water inlet valve 20. Since the water level detection component 40 is electrically connected to the water inlet valve 20, when it is detected that the water level in the heating chamber 11 reaches the highest water level, the water inlet valve 20 is closed to cut off the water inlet pipe 19 and the heating chamber 11. By closing the water inlet valve 20 to cut off the water inlet pipe 19 and the heating chamber 11 when the water level in the heating chamber 11 reaches the highest water level, the hot water tank module 100 can control the water volume stored in the heating chamber 11, avoiding the water in the heating chamber 11 from overflowing when the water is heated to boiling. For example, when the water level in the heating chamber 11 is at the highest water level, there is a cavity formed above the liquid level between the liquid level in the heating chamber 11 and the upper cover plate 14 assembly 12. At this time, by controlling the water inlet valve 20 to stop water inlet, a cavity can be formed above the liquid level, thus avoiding the water in the heating chamber 11 from overflowing when the water is heated to boiling and ensuring the safety of the heating tank 10.

[0067] According to some embodiments of the present invention, refer to Figure 4, the upper cover plate 14 assembly 12 includes an upper cover plate 14. An inlet hole 15 is formed on the upper cover plate 14. A water inlet pipe 19 is connected to the upper cover plate 14 and communicates with the inlet hole 15. By providing the inlet hole 15 on the upper cover plate 14 and making the inlet hole 15 communicate with the water inlet pipe 19, the heating tank 10 can be replenished with water, ensuring that enough hot water can be stored in the heating tank 10.

[0068] According to some embodiments of the present invention, referring to Figure 1 , the upper cover plate 14 assembly 12 includes an upper cover plate 14.

One end of an outlet pipe 18 is connected to the outlet hole 16, and the other end of the outlet pipe 18 extends to the upper cover plate 14 and is fixed to the upper cover plate 14. By forming the outlet hole 16 at the bottom of the tank body, the water in the heating tank 10 can still be discharged when the water level is low and the water volume is small. By connecting one end of the outlet pipe 18 to the outlet hole 16 and extending the other end of the outlet pipe 18 to the upper cover plate 14, the outlet pipe 18 can not occupy too much space; and the outlet pipe 18 can become a part of the hot water tank assembly, facilitating overall modularization, thereby making the disassembly and assembly of the hot water tank assembly more convenient.

[0069] According to some embodiments of the present invention, referring to Figure 2 , an avoidance hole for avoiding the outlet pipe 18 is formed on the base 50. By making the base 50 include the avoidance hole for avoiding the outlet pipe 18, interference between the base 50 and the outlet pipe 18 can be prevented; and by accommodating the outlet pipe 18 in the avoidance hole, the base 50 can limit the position of the outlet pipe 18, making the position of the outlet pipe 18 fixed.

[0070] According to some embodiments of the present invention, referring to Figures 1-3 , the outlet pipe 18 includes a first pipe section 22, a second pipe section 23, and a third pipe section 24. The first pipe section 22 is connected between the outlet hole 16 and the pump inlet of the water pump 30. The second pipe section 23 is connected between the pump outlet of the water pump 30 and the third pipe section 24. The third pipe section 24 is located above the upper cover plate 14 and the third pipe section 24 is fixed to the upper cover plate 14. By dividing the outlet pipe 18 into the first pipe section 22, the second pipe section 23, and the third pipe section 24, and connecting the first pipe section 22 between the outlet hole 16 and the pump inlet of the water pump 30, connecting the second pipe section 23 between the pump outlet of the water pump 30 and the third pipe section 24, and making the third pipe section 24 located above the upper cover plate 14 and fixed to the upper cover plate 14, the outlet pipe 18 can not occupy too much space, and at the same time, it can also ensure that the outlet pipe 18 has the function of guiding and discharging the water passing through the outlet hole 16. By connecting both the first pipe section 22 and the second pipe section 23 to the water pump 30 and fixing the third pipe section 24 to the upper cover plate 14, the position of each section of the outlet pipe 18 can be ensured to be fixed.

[0071] For example, the hot water tank module 100 includes a flow meter, which is connected in series in the second pipe section 23. By arranging a flow meter in the water outlet pipe 18, the flow rate of the water flowing out of the water outlet pipe 18 can be monitored to avoid the water flowing out too fast or too slow, so as to meet the needs of users.
