[0049] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0050] Next, refer to Figures 1-7Describe a hot water tank module 100 and a drinking water device according to an embodiment of the present utility model.

[0051] The hot water tank module 100 according to the first aspect embodiment of the present utility model is used for a drinking water device and includes: a base 10, a heating tank 20, and a water pipeline assembly 40.

[0052] The base 10 is disposed on the lower side of the heating tank 20 for supporting and fixing the heating tank 20. For example, a hot water tank installation groove 11 is provided on the base 10, and the lower side of the heating tank 20 is received in the hot water tank installation groove 11. By providing the hot water tank installation groove 11 on the base 10 and receiving the lower side of the heating tank 20 in the hot water tank installation groove 11, the heating tank 20 can be more firmly fixed to prevent the heating tank 20 from tipping over. For example, a limiting plate 12 is provided on the base 10, and a plurality of limiting plates 12 are arranged along the circumferential direction of the base 10 and extend upward in the vertical direction. By providing the limiting plate 12 on the base 10, the base 10 can more fully limit the heating tank 20, avoid the heating tank 20 from tipping over, and ensure that the heating tank 20 can be erected and fixed.

[0053] Optionally, the base 10 is an integrally formed part. By making the base 10 integrally formed, the number of parts of the hot water tank module 100 can be reduced, and the assembly difficulty of the hot water tank module 100 can be lowered.

[0054] For example, referring to Figures 1-5 , the hot water tank module 100 includes a water pump 43. The water pump 43 is disposed on the side of the heating tank 20. The base 10 includes a water pump base 13 and a hot water tank base 14. The water pump base 13 is disposed on the lower side of the water pump 43 for supporting and fixing the water pump 43. The hot water tank base 14 is disposed on the lower side of the heating tank 20 for supporting and fixing the heating pipe. The base 10 is an integrally formed part.

[0055] Referring to Figure 4 , the heating tank 20 is installed on the base 10 and includes a tank body 21 and an upper cover assembly 22. A heating cavity 23 is formed inside the tank body 21. When the hot water tank stores water or heats water, the water is received in the heating cavity 23. For example, the tank body 21 includes an outer shell and an inner shell. The heating cavity 23 is defined inside the inner shell, and the water is received in the heating cavity 23. A heat insulation layer is defined between the outer shell and the inner shell for insulating the water inside the tank body 21 to prevent the heat of the heated water from dissipating and causing the water temperature to decrease.

[0056] Optionally, the hot water tank module 100 includes a heating device. The heating device is disposed between the heating tank 20 and the base 10. The heating device includes a heating resistor. By energizing the resistor, the resistor generates heat, and the heat is transferred to the water inside the inner shell to raise the water temperature to achieve the effect of heating the water.

[0057] Optionally, referring to Figure 1, the hot water tank module 100 includes a temperature sensing device. By using the temperature sensing device to sense the temperature of the water in the tank body 21, the heating of the water can be controlled or maintained at the set temperature, which can meet the needs of users. For example, the hot water tank module 100 includes two temperature sensing devices, one of which is arranged at the bottom of the tank body 21, and the other temperature sensing device is connected to the top of the tank body 21 through a fastener.

[0058] Referring to Figures 1-5 , the upper cover plate assembly 22 is covered on the top of the tank body 21, and an exhaust structure 26 is provided on the upper cover plate. The exhaust structure 26 communicates the heating chamber 23 with the external environment. By providing the exhaust structure 26 on the upper cover plate and making the exhaust structure 26 communicate the heating chamber 23 with the external environment, the pressure inside the tank body 21 can be balanced with the atmospheric pressure, avoiding the explosion and rupture of the heating tank 20 caused by the excessive pressure in the tank due to the expansion of the water in the tank body 21 when the water temperature rises; and, since the heating temperature of the water in the heating tank 20 is not limited by the pressure, the heating temperature of the water in the heating tank 20 can be increased, for example, heating the water to boiling, to meet the needs of users for higher water temperatures.

[0059] Referring to Figure 4 , the water pipeline assembly 40 includes a water inlet pipe 41 and a water outlet pipe 42, and both the water inlet pipe 41 and the water outlet pipe 42 are connected to the heating tank 20. Water can enter the heating tank 20 from the water inlet pipe 41 and can leave the heating tank 20 from the water outlet pipe 42. For example, the water outlet pipe 42 is connected to a faucet, and the user can receive the hot water flowing out of the water outlet pipe 42 by opening the faucet.

[0060] Optionally, the water inlet pipe 41 includes a water inlet valve, and the water inlet valve can control the connection or disconnection state between the water inlet pipe 41 and the heating tank 20 to control the water supply or stop the water supply to the heating tank 20.

[0061] Optionally, the hot water tank assembly includes a water pump 43, and the water pump 43 is connected in series to the water outlet pipe 42, and the water outlet pipe 42 is connected to a faucet. When the user needs to receive hot water, the water pump 43 starts and pumps the water out of the heating tank 20, and the water flows through the water outlet pipe 42 and flows out of the faucet.

[0062] According to the hot water tank module 100 of the first aspect embodiment of the present invention, by providing the exhaust structure 26 on the upper cover plate and enabling the exhaust structure 26 to communicate the heating chamber 23 with the external environment, the pressure inside the heating tank 20 can be balanced with the external air pressure, avoiding the heating temperature of the water in the heating tank 20 being limited by the pressure and unable to be increased, so that the heating tank 20 can heat the water to a higher temperature to meet the needs of users.

[0063] According to some embodiments of the present invention, referring to Figure 7, the hot water tank module 100 includes an exhaust pipe 60. The exhaust structure 26 includes an exhaust hole 27. The exhaust pipe 60 is connected to the upper cover plate and is in communication with the exhaust hole 27. Gas can enter the exhaust pipe 60 through the exhaust hole 27 and be discharged from the heating tank 20 to relieve the pressure inside the heating tank 20. For example, the exhaust hole 27 is in communication with the external environment. By connecting the exhaust pipe 60 to the upper cover plate and making it in communication with the exhaust hole 27, the gas inside the heating tank 20 can enter the exhaust pipe 60 through the exhaust hole 27 and be discharged to the external environment, so that the pressure inside the heating tank 20 is balanced with the atmospheric pressure. When the heating tank 20 heats the water inside the tank, it can prevent the heating tank 20 from bursting due to excessive pressure inside the heating tank 20, improving the safety of the heating tank 20; when taking water, the exhaust pipe 60 can ensure that the inside of the heating tank 20 is in communication with the atmosphere, and no negative pressure will be generated inside the tank, so that the user can smoothly take out the hot water.

[0064] According to some embodiments of the present invention, referring to Figure 3 , the exhaust pipe 60 is detachably connected to the upper cover plate. By making the exhaust pipe 60 detachably connected to the upper cover plate, the exhaust pipe 60 can be more conveniently disassembled during replacement or cleaning, reducing the maintenance difficulty of the exhaust pipe 60 for maintenance personnel. Moreover, exhaust pipes 60 of different length specifications can also be adopted as needed, so that the exhaust pipe 60 can meet the requirements of more installation environments.

[0065] According to some embodiments of the present invention, referring to Figures 1-3 , the upper cover plate includes a cover plate body 28 and an exhaust seat 29. The exhaust seat 29 is provided on the upper side of the cover plate body 28. An exhaust cavity is provided inside the exhaust seat 29. The exhaust structure 26 includes an exhaust cavity. The exhaust pipe 60 is connected to the exhaust seat 29, and the exhaust cavity communicates the exhaust hole 27 with the exhaust pipe 60. For example, the exhaust seat 29 is integrally formed with the upper cover plate, which can make the connection between the exhaust seat and the upper cover plate more stable. By providing the exhaust seat 29 on the upper cover plate and connecting the exhaust pipe 60 to the exhaust seat 29, the fixing of the exhaust pipe 60 can be made more stable and reliable.

[0066] By making the exhaust cavity communicate the exhaust hole 27 with the exhaust pipe 60, a flow channel can be provided for the gas inside the heating tank 20. The gas can enter the exhaust cavity through the exhaust hole 27 and then be discharged from the exhaust pipe 60, so that the pressure inside the heating tank 20 is balanced with the atmospheric pressure. When the heating tank 20 heats the water inside the tank, it can prevent the heating tank 20 from bursting due to excessive pressure inside the heating tank 20, improving the safety of the heating tank 20.

[0067] According to some embodiments of the present invention, referring to Figure 7, the exhaust holes 27 are multiple and arranged at intervals, and each exhaust hole 27 communicates with the exhaust cavity. By arranging the exhaust holes 27 as multiple and at intervals, the gas in the heating tank 20 can be discharged more easily; moreover, when one of the exhaust holes 27 is blocked, it can ensure that the gas still has a passage to flow to the external environment, improving the safety of the heating tank 20. By making each exhaust hole 27 communicate with the exhaust cavity, each exhaust hole 27 can lead to the exhaust pipe 60 and flow to the external environment.

[0068] According to some embodiments of the present invention, referring to Figure 3 , the upper cover plate includes a cover plate body 28 and a pipe seat 30. The pipe seat 30 is provided on the cover plate body 28, and a first fitting groove 31 is formed on the pipe seat 30. The exhaust pipe 60 is fitted in the first fitting groove 31. By forming the first fitting groove 31 on the pipe seat 30 and fitting the exhaust pipe 60 in the first fitting groove 31, the pipe seat 30 can limit the exhaust pipe 60 to prevent the exhaust pipe 60 from moving and interfering with other components, making the fixation of the exhaust pipe 60 more sufficient.

[0069] According to some embodiments of the present invention, referring to Figure 1 and Figure 7 , a water inlet hole 33 is formed on the upper cover plate. The water inlet pipe 41 is connected to the upper cover plate and communicates with the water inlet hole 33. By providing the water inlet hole 33 on the upper cover plate and making the water inlet hole 33 communicate with the water inlet pipe 41, the heating tank 20 can be replenished with water, ensuring that enough hot water can be stored in the heating tank 20.

[0070] For example, the water inlet pipe 41 includes a water inlet valve, and the water inlet valve can open or close the water inlet pipe 41. By providing the water inlet valve, the volume of water stored in the heating tank 20 can be controlled to avoid the heating tank 20 being permanently full of water. For example, a certain amount of air can be stored in the heating tank 20. When the heating tank 20 heats the water to boiling, part of the air in the heating tank 20 can serve as the space for the water to boil, avoiding part of the water entering the outlet pipe due to the expansion of the water volume.

[0071] According to some embodiments of the present invention, referring to Figure 1 , the upper cover plate includes a cover plate body 28 and a water inlet seat 34. The water inlet seat 34 is provided on the upper side of the cover plate body 28. There is a water inlet cavity in the water inlet seat 34. The water inlet pipe 41 is connected to the water inlet seat 34, and the water inlet cavity communicates the water inlet hole 33 with the water inlet pipe 41. By providing the water inlet seat 34 on the cover plate body 28 and connecting the water inlet pipe 41 to the water inlet seat 34, the connection between the water inlet pipe 41 and the cover plate body 28 can be made more sufficient, ensuring the fixation of the water inlet pipe 41.

[0072] For example, the hot water tank module 100 further includes an exhaust pipe 60. The exhaust structure 26 includes an exhaust hole 27. The exhaust pipe 60 is connected to the upper cover plate and communicates with the exhaust hole 27. An inlet hole 33 is formed on the upper cover plate. The water inlet pipe 41 is connected to the upper cover plate and communicates with the inlet hole 33. The upper cover plate includes a cover plate body 28 and an exhaust seat 29. The exhaust seat 29 is arranged on the upper side of the cover plate body 28. An exhaust cavity is provided in the exhaust seat 29. The exhaust structure 26 includes an exhaust cavity. The exhaust pipe 60 is connected to the exhaust seat 29. The exhaust cavity communicates the exhaust hole 27 with the exhaust pipe 60.

A water inlet cavity is provided in the water inlet seat 34. The water inlet pipe 41 is connected to the water inlet seat 34. The water inlet cavity communicates the inlet hole 33 with the water inlet pipe 41. The water inlet seat 34 is connected to the exhaust seat 29 and the two are integrally formed.

[0073] According to some embodiments of the present invention, referring to Figures 1-5 , the hot water tank module 100 further includes a water pump 43. The water pump 43 is connected in series to the water outlet pipe 42. By connecting the water pump 43 in series to the water outlet pipe 42, the water in the heating tank 20 can be pumped to a higher position by the water pump 43, which is convenient for the user to draw water subsequently. And, the water pump 43 can act as a switch. When the water pump 43 is turned on, water can flow out from the water outlet pipe 42. When the water pump is turned off, water cannot flow out from the water outlet pipe 42.

[0074] According to some embodiments of the present invention, referring to Figure 4 , the water pump 43 is installed on the base 10. For example, the base 10 includes a hot water tank base 14 and a water pump base 13. The hot water tank base 14 is connected to the water pump base 13. The water pump 43 is installed on the water pump base 13. By installing the water pump 43 on the base 10, the water pump 43 can be fixed relative to the base 10, preventing the water pump 43 from vibrating and moving during operation and interfering with other components.

[0075] According to some embodiments of the present invention, referring to Figure 2 , a water outlet hole 36 is formed at the bottom of the tank body 21. One end of the water outlet pipe 42 is connected to the water outlet hole 36, and the other end of the water outlet pipe 42 extends to the upper cover plate. By forming the water outlet hole 36 at the bottom of the tank body 21, water can still be discharged when the water level in the heating tank 20 is low and the water volume is small. By connecting one end of the water outlet pipe 42 to the water outlet hole 36 and extending the other end of the water outlet pipe 42 to the upper cover plate, the water outlet pipe 42 does not occupy too much space, and at the same time, it can also ensure that the water outlet pipe 42 has the function of guiding and discharging the water passing through the water outlet hole 36.

[0076] According to some embodiments of the present utility model, an avoidance hole for avoiding the water outlet pipe 42 is formed on the base 10.

By dividing the water outlet pipe 42 into the first pipe section 44, the second pipe section 45, and the third pipe section 46, and connecting the first pipe section 44 between the water outlet hole 36 and the pump inlet of the water pump 43, the second pipe section 45 between the pump outlet of the water pump 43 and the third pipe section 46, and the third pipe section 46 being located above the upper cover plate and fixed to the upper cover plate, the water outlet pipe 42 can be prevented from occupying too much space, while also ensuring that the water outlet pipe 42 can guide and discharge the water passing through the water outlet hole 36. By connecting both the first pipe section 44 and the second pipe section 45 to the water pump 43 and fixing the third pipe section 46 to the upper cover plate, the position of each section of the water outlet pipe 42 can be ensured to be fixed.

[0078] For example, the hot water tank module 100 includes a flow meter 48, and the flow meter 48 is connected in series in the second pipe section 45. By providing a flow meter 48 in the water outlet pipe 42 section, the flow rate of the water discharged from the water outlet pipe 42 section can be controlled, avoiding the water flow being too fast or too slow to meet the user's needs.

[0079] According to some embodiments of the present utility model, referring to Figure 3 , the hot water tank module 100 includes an exhaust pipe 60, the exhaust structure 26 includes an exhaust hole 27, the exhaust pipe 60 is connected to the upper cover plate and communicated with the exhaust hole 27. The upper cover plate includes a cover body 28 and a pipe seat 30. The pipe seat 30 is provided on the cover body 28, and a first fitting groove 31 and a second fitting groove 32 are formed on the pipe seat 30. The exhaust pipe 60 is fitted in the first fitting groove 31, and the third pipe section 46 is fitted in the second fitting groove 32. By providing a pipe seat 30 on the upper cover plate, and fitting the exhaust pipe 60 in the first fitting groove 31 and the third pipe section 46 in the second fitting groove 32, both the exhaust pipe 60 and the third pipe section 46 of the water outlet pipe 42 can be limited, enabling the exhaust pipe 60 and the third pipe section 46 of the water outlet pipe 42 to be fully fixed. By providing both the first fitting groove 31 and the second fitting groove 32 on the pipe seat 30, the pipe seat 30 can simultaneously achieve the purpose of limiting both the exhaust pipe 60 and the third pipe section 46 of the water outlet pipe 42, saving space and cost.

[0080] For example, the socket 30 can be integrally formed with the upper cover plate, reducing the number of parts of the hot water tank module 100, reducing the assembly difficulty of the hot water tank module 100, and making the connection between the socket 30 and the heat pipe module more sufficient.

[0081] According to some embodiments of the present invention, referring to Figure 3 , the water pipeline assembly 40 includes a fixing plate 47, and the fixing plate 47 is connected between the outer peripheral wall of the exhaust pipe 60 and the outer peripheral wall of the water outlet pipe 42. The fixing plate 47 is connected to the socket 30 by fasteners. The fixing plate 47 can limit the upward movement of the exhaust pipe 60 and the water outlet pipe 42, preventing the exhaust pipe 60 and the water outlet pipe 42 from moving upward and interfering with other components, and avoiding the bending of the pipes caused by the upward movement of the exhaust pipe 60 and the water outlet pipe 42, which reduces the service life of the pipes. By connecting the fixing plate 47 between the outer peripheral wall of the exhaust pipe 60 and the outer peripheral wall of the water outlet pipe 42, the exhaust pipe 60 and the water outlet pipe 42 can be limited in the upward direction, and the positions of the exhaust pipe 60 and the water outlet pipe 42 are more stable. By connecting the fixing plate 47 to the socket 30 by fasteners, the fixing plate 47 can be fixed relative to the socket 30, and the fixing plate 47 can limit the exhaust pipe 60 and the water outlet pipe 42 more sufficiently.

[0082] According to some embodiments of the present invention, referring to Figure 3 , an avoidance groove 37 for avoiding the fixing plate 47 is formed on the socket 30. By forming an avoidance groove 37 for avoiding the fixing plate 47 on the socket 30 and accommodating the fixing plate 47 in the avoidance groove 37, interference between the socket 30 and the fixing plate 47 can be prevented; and by accommodating the fixing plate 47 in the avoidance groove 37, installation prompts can be given to the user, making the installation of the fixing plate 47 more convenient.

[0083] Wherein, fixing columns 38 are provided on the bottom wall of the avoidance groove 37. Referring to Figure 3 , the fixing plate 47 is connected to the fixing columns 38 by fasteners. For example, the fixing plate 47 is connected to the fixing columns 38 by screws. By connecting the fixing plate 47 to the fixing columns 38 by fasteners, the connection between the fixing plate 47 and the fixing columns 38 can be made more sufficient; and the fixing plate 47 and the fixing columns 38 can be made detachable, facilitating the removal of the fixing plate 47 during maintenance to check or remove the exhaust pipe 60 or the water outlet pipe 42.

[0084] According to some embodiments of the present invention, referring to Figure 3, the hot water tank module 100 includes a water inlet valve for controlling the on-off between the water inlet pipe 41 and the heating chamber 23. If the heating chamber 23 remains full of water, when the user draws water, the water inlet pipe 41 continuously replenishes water, and 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 including a water inlet valve in the heat pipe module, the hot water tank module 100 can control the water volume stored in the heating chamber 23 to prevent water from boiling over; it can also control the water replenishment time in the heating chamber 23. For example, when the user draws water, the water inlet valve is closed, so that the water obtained by the user can meet the temperature requirement.

[0085] According to some embodiments of the present invention, the hot water tank module 100 includes a water outlet valve for controlling the on-off between the water outlet pipe 42 and the heating chamber 23. By including a water outlet valve in the hot water tank module 100, water can be discharged when the user needs it and closed when the user does not need it.

[0086] For example, the hot water tank module 100 further includes a detection device for detecting the opening and closing of the water outlet valve. By enabling the detection device to detect the opening and closing of the water outlet valve, information on whether the user is drawing hot water can be obtained, thereby controlling the opening and closing of the water inlet valve. For example, when the user draws hot water, the water outlet valve opens, and the detection device detects the opening of the water outlet valve and controls the water inlet valve to close, ensuring that the water obtained by the user can meet the temperature requirement. When the user does not draw hot water, the water outlet valve closes, and the detection device detects the closing of the water outlet valve, which can control the water inlet valve to open, ensuring that there is enough water stored in the heating tank 20.

[0087] According to some embodiments of the present invention, referring to Figure 5 , the hot water tank module 100 further includes a water level detection component 50 disposed in the heating tank 20 and used for detecting the water level in the heating chamber 23. The water level in the heating chamber 23 has a maximum water level. When the water level in the heating chamber 23 is at the maximum water level, a cavity is formed above the liquid surface by spacing apart the liquid surface in the heating chamber 23 from the upper cover assembly 22. By spacing apart the liquid surface in the heating chamber 23 from the upper cover assembly 22 to form a cavity above the liquid surface when the water level in the heating chamber 23 is at the maximum water level, the water in the heating chamber 23 will not be in a full water state, avoiding the water in the heating chamber 23 from overflowing when the water is heated to boiling.

[0088] For example, the water level detection component 50 includes water level probes, and multiple water level probes are spaced apart. The water level probes include a common probe 51, a high water level probe 52, and a low water level probe 53. The high water level probe 52 is used to detect whether the water in the heating chamber 23 exceeds the maximum water level, and the low water level probe 53 is used to detect whether the water in the heating chamber 23 is lower than the minimum water level.

[0089] The hot water tank module 100 further includes a water inlet valve for controlling the on-off between the water inlet pipe 41 and the heating chamber 23. The water level detection component 50 is electrically connected to the water inlet valve to close the water inlet valve to cut off the water inlet pipe 41 and the heating chamber 23 when the water level in the heating chamber 23 reaches the highest water level. By closing the water inlet valve to cut off the water inlet pipe 41 and the heating chamber 23 when the water level in the heating chamber 23 reaches the highest water level, the hot water tank module 100 can control the amount of water stored in the heating chamber 23 and prevent the water in the heating chamber 23 from overflowing when the water is heated to boiling. For example, when the water level in the heating chamber 23 is at the highest water level, a cavity is formed above the liquid level between the liquid level in the heating chamber 23 and the upper cover assembly 22. At this time, by controlling the water inlet valve to stop water inlet, a cavity can be formed above the liquid level, thus preventing the water in the heating chamber 23 from overflowing when the water is heated to boiling and ensuring the safety of the heating tank 20.

[0090] According to some embodiments of the present invention, when the water level in the heating chamber 23 is at the highest water level, the distance in the vertical direction between the liquid level in the heating chamber 23 and the upper cover assembly 22 is a, and the range of a is 10 mm to 40 mm. For example, the value of a can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, etc. By making a not less than 10 mm, there is enough space between the water in the heating chamber 23 and the top of the hot water tank to ensure that the water will not overflow when heated to boiling. By making a not more than 40 mm, more water can be accommodated in the heating chamber 23, avoiding waste of the space of the heating chamber 23.

[0091] According to some embodiments of the present invention, the water level in the heating chamber 23 has a lowest water level, which is lower than the highest water level. The water level detection component 50 is used to open the water inlet valve to connect the water inlet pipe 41 and the heating chamber 23 when the water level in the heating chamber 23 is detected to be lower than the lowest water level. By opening the water inlet valve to connect the water inlet pipe 41 and the heating chamber 23 when the water level in the heating chamber 23 is lower than the lowest water level, the heating chamber 23 can have sufficient water to meet the water consumption requirements of users; and it can prevent dry burning due to no water in the heating chamber 23, which may cause the heating tank 20 to continuously heat up and pose a danger; in addition, it can also prevent the water pump 43 from pumping air.

[0092] According to some embodiments of the present invention, when the water level in the heating chamber 23 is at the lowest water level, the distance in the vertical direction between the liquid level in the heating chamber 23 and the bottom wall of the tank body 21 is b, and the value range of b is 5 mm to 20 mm. By making the value of b not less than 5 mm, it can be avoided that the water in the heating chamber 23 is too little to meet the water consumption requirements of users; by making the value of b not more than 20 mm, it can be avoided that the water replenishment is too frequent, resulting in too frequent heating of the water and wasting energy.

[0093] Among them, when the water level in the heating chamber 23 is at the lowest water level, the water level surface inside the hot water tank is higher than the highest surface of the impeller of the water pump 43. By making the water level surface inside the hot water tank higher than the highest surface of the impeller of the water pump 43, it can ensure that the water pump 43 can work normally.

[0094] According to some embodiments of the present invention, referring to Figure 6 , the hot water tank module 100 includes a water outlet faucet 70. An outlet water pipe 72 and an exhaust pipe 60 are formed in the water outlet faucet 70 and are separated from each other. If the water in the outlet water pipe 72 enters the exhaust pipe 60, it may cause blockage of the exhaust pipe 60 and hinder the discharge of gas; if the water vapor in the exhaust pipe 60 enters the outlet water pipe 72 and is discharged from the water outlet end 76, since the temperature of the water vapor is relatively high, it may accidentally injure the user. By separating the outlet water pipe 72 and the exhaust pipe 60 of the water outlet faucet 70 from each other, it is possible to avoid the interference of water or gas between the outlet water pipe 72 and the exhaust pipe 60, ensure the smooth discharge of the water vapor in the exhaust pipe 60, and also avoid accidental injury to the user.

[0095] Among them, the outlet water pipe 72 is connected to the water outlet pipe 42. Referring to Figure 6 , a ventilation hole 73 is formed on the water outlet faucet 70. The ventilation hole 73 communicates the exhaust pipe 60 with the external environment, and the exhaust pipe 60 is connected to the exhaust pipe 60. By connecting the outlet water pipe 72 to the water outlet pipe 42, it can ensure that the user can draw hot water from the water outlet pipe 42. By making the ventilation hole 73 communicate the exhaust pipe 60 with the external environment and the exhaust pipe 60 is connected to the exhaust pipe 60, it can ensure that the gas in the heating chamber 23 can be connected to the external environment, balance the pressure in the heating chamber 23 with the atmospheric pressure, and avoid bursting due to excessive pressure in the heating chamber 23.

[0096] According to some embodiments of the present invention, referring to Figure 6 , the water outlet faucet 70 includes a first water outlet section 74 and a second water outlet section 75 arranged at an angle. The first water outlet section 74 is connected between the water outlet pipe 42 and the second water outlet section 75. The free end of the second water outlet section 75 forms a water outlet end 76. The ventilation hole 73 is formed in the second water outlet section 75 and is adjacent to the connection between the first water outlet section 74 and the second water outlet section 75. By making the free end of the second water outlet section 75 form a water outlet end 76 and making the ventilation hole 73 be formed in the second water outlet section 75 and adjacent to the connection between the first water outlet section 74 and the second water outlet section 75, the ventilation hole 73 can be made to be far away from the water outlet end 76, which can avoid the interference of water or gas between the outlet water pipe 72 and the exhaust pipe 60, ensure the smooth discharge of the water vapor in the exhaust pipe 60, and also avoid accidental injury to the user.

[0097] For example, the water outlet pipe 72 and the exhaust pipe 60 are separately accommodated in the water outlet faucet 70. One end of the water outlet pipe 72 communicates with the second water outlet end 76, so that hot water can be discharged from the second water outlet end 76 for users to use; one end of the exhaust pipe 60 communicates with the vent hole 73, so that the gas in the heating cavity 23 is communicated with the atmosphere, avoiding the explosion and damage caused by excessive pressure in the heating cavity 23 when heating water in the heating cavity 23, and ensuring the safety in the heating cavity 23.

[0098] For example, the first water outlet section 74 is placed horizontally, and the second water outlet section 75 is placed vertically. By placing the second water outlet section 75 vertically, when the user does not draw water, the water can fall back by gravity, so that when the faucet is closed, the hot water is located in the heating cavity 23 that can keep warm, and no hot water is stored in the second water outlet section 75, ensuring that the hot water can be fully insulated. When the user needs to draw hot water, the temperature of the water can meet the user's needs.

[0099] According to some embodiments of the present invention, the exhaust structure 26 always communicates the heating cavity 23 with the external environment. By making the exhaust structure 26 always communicate the heating cavity 23 with the external environment, the pressure in the heating tank 20 can always be balanced with the external air pressure, avoiding the potential safety hazard caused by excessive pressure in the heating tank 20 and further ensuring the safety of the heating tank 20.

[0101] According to the drinking water device of the embodiment of the present utility model, by including the hot tank module 100 of the first aspect embodiment of the present utility model, and the exhaust structure 26 of the hot tank module 100 communicates the heating cavity 23 with the external environment, the hot tank module 100 can heat the water to a higher temperature, thereby meeting the needs of users.

[0102] For example, the drinking water device can be an under-counter drinking machine, or it can also be a water purifier, a water dispenser or a drinking water device with heating or refrigeration functions.

[0103] Optionally, the drinking water device has a water purification function.

[0104] Optionally, on the basis of realizing the function of providing hot water, further, the drinking water device can also have the function of providing cold water. Further, the drinking water device can also have the function of providing normal temperature water.
