Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, specifically to water tank modules and drinking water equipment. Background Technology

[0002] With the increasing demand for healthy drinking water, water dispensers, water purifiers, and other drinking water equipment have gained widespread attention due to their high efficiency and convenience. However, traditional drinking water equipment, especially water dispensers that can produce both hot and cold water, has many internal components. These components are mostly connected by silicone tubing to create water circuits, making the internal water routing more complex. This not only increases assembly complexity and the risk of missing or incorrect components, but also makes the silicone tubing prone to aging and developing odors after prolonged use, affecting drinking water quality. Furthermore, leaks at the tubing connections can compromise product reliability and lifespan. Utility Model Content

[0003] In view of this, the present invention provides a water tank module and drinking water equipment to solve the problems of existing drinking water equipment having many internal wiring pipes, complex assembly, low efficiency, easy aging, and high safety hazards.

[0004] In a first aspect, this utility model provides a water tank module for use in drinking water equipment. The drinking water equipment includes a hot water system, a cooling water system, and a water outlet. The water tank module includes:

[0005] The water tank has a water storage chamber inside and a first water outlet and a second water outlet. The first water outlet is suitable for connection to a hot water system, and the second water outlet is suitable for connection to a cooling water system.

[0006] The water tank water circuit board is integrated with the water tank. The water tank water circuit board integrates water circuits for connecting the water tank with the cooling water system and / or, the cooling water system with the water outlet and / or, the hot water system with the water outlet and / or, and the hot water system with the cooling water system.

[0007] Beneficial effects: By adopting an integrated water tank and water circuit board, the step of separately disassembling and assembling the water tank and water circuit board is eliminated, improving the overall assembly efficiency. Furthermore, by integrating water circuits within the water tank and water circuit board to connect the water tank to the cooling water system, and / or, the cooling water system to the water outlet, and / or, the hot water system to the water outlet, and / or, the hot water system to the cooling water system, this replaces the traditional silicone tubing connection method. Multiple water circuits are integrated into a single, efficient, and compact water tank and water circuit board, achieving direct connection between the internal water circuits of the water tank, hot water system, cooling water system, and water outlet. This not only simplifies the structure but also avoids the aging and odor problems associated with silicone tubing, as well as the issues of a chaotic and unsafe water circuit system. It improves the overall sealing, stability, and safety of the machine, solving the problems of numerous internal wiring and piping, complex assembly, low efficiency, easy aging, and high safety hazards in existing drinking water equipment. Furthermore, by assembling the water tank and water circuit board into a module, and integrating multiple water circuits within the water circuit board, different functional modules can be flexibly combined as needed. This greatly simplifies the assembly steps of the water circuit system, improves the production efficiency of drinking water equipment, and also facilitates the later maintenance and upgrade of drinking water equipment. This meets diverse needs while reducing production and maintenance costs.

[0008] In one alternative implementation, the water tank circuit board integrates:

[0009] The inlet of the ice tank is integrated with the second outlet, and the outlet is connected to the inlet of the chilled water system.

[0010] The water outlet of the ice tank is connected to the outlet of the chilled water system at its inlet and to the cold water inlet of the outlet nozzle at its outlet.

[0011] Beneficial Effects: The water circuit board integrates a main body, on which an ice tank inlet water circuit is integrated. The inlet end of the ice tank inlet water circuit is integrated with the second outlet of the water tank, and the outlet end of the ice tank inlet water circuit is connected to the inlet of the chilled water system, thus supplying water to the chilled water system. Furthermore, the main body of the water circuit board also integrates an ice tank outlet water circuit. The inlet end of the ice tank outlet water circuit is connected to the outlet of the chilled water system, and the outlet end of the ice tank outlet water circuit is connected to the cold water inlet of the water outlet, thus delivering the cold water prepared in the chilled water system to the water outlet for user use. The high degree of integration of the ice tank inlet and outlet water circuits on the water circuit board reduces the number of parts and facilitates the assembly of the chilled water system with the water tank and water outlet.

[0012] In one optional embodiment, a first valve is provided on the water outlet of the ice tank, and the water tank includes:

[0013] The cold water solenoid valve, installed at the first valve port, is used to control the opening and closing of the water outlet of the ice tank.

[0014] Beneficial effects: The water tank module also includes a cold water solenoid valve, which facilitates the control of the on / off of the ice tank water outlet. By assembling the cold water solenoid valve, water tank, and water tank circuit board into a module, the assembly steps of the water system are greatly simplified, the production efficiency of the drinking water equipment is improved, and the later maintenance and upgrade of the drinking water equipment are also facilitated.

[0015] In one alternative implementation, the water tank circuit board integrates:

[0016] The circulating sterilization water circuit has its inlet connected to the outlet of the hot water system and its outlet connected to the outlet of the cooling water system.

[0017] Beneficial Effects: By integrating a circulating sterilization water circuit into the water tank's water circuit board, connecting the outlets of the hot water system and the cooling water system, this independent circulating sterilization water circuit allows the high-temperature hot water produced by the hot water system to be passed into the cooling water system for high-temperature sterilization and disinfection. This improves the hygiene performance of the drinking water equipment and enhances the user experience. Furthermore, the hot water system, circulating sterilization water circuit, cooling water system, and water tank form a loop, enabling high-temperature circulating flushing and sterilization of the cooling water system, hot water system, and water tank, further improving the overall hygiene and cleanliness of the machine and ensuring water safety. In addition, the circulating sterilization water circuit formed on the water tank's water circuit board reduces the use of silicone tubing, resulting in a smaller number of silicone tubes and a neater, more aesthetically pleasing structure after assembly.

[0018] In one optional embodiment, the outlet end of the circulating sterilization water path is connected to the ice tank outlet water path located between the cooling water system and the water outlet, and the outlet end of the circulating sterilization water path is located between the cold water solenoid valve on the ice tank outlet water path and the water outlet of the cooling water system.

[0019] Beneficial effects: The outlet of the circulating sterilization water circuit is located upstream of the cold water solenoid valve. Therefore, during the high-temperature sterilization and disinfection of the cooling water system of the drinking water equipment, the hot water produced by the hot water system will not flow through the cold water solenoid valve. On the one hand, this reduces the damage to the cold water solenoid valve caused by the impact of high-temperature and cold water. On the other hand, it reduces the retention of hot water in the cold water solenoid valve, which can lead to temperature cross-contamination in the drinking water equipment. This improves the independence between the cold and hot water systems of the drinking water equipment and avoids heat exchange between them. Thus, while achieving efficient sterilization, it also maintains the temperature stability of both the cold and hot water systems of the drinking water equipment.

[0020] In one alternative implementation, the water tank circuit board also integrates:

[0021] The hot water faucet's inlet is connected to the outlet of the hot water system, and its outlet is connected to the hot water inlet of the faucet.

[0022] Beneficial effects: The cold water inlet of the water outlet is connected to the water outlet of the ice tank, and the hot water inlet of the water outlet is connected to the hot water outlet of the faucet. Cold water and hot water flow to the cold water inlet and hot water inlet of the water outlet respectively through the water outlet of the ice tank and the hot water outlet of the faucet. This can prevent the cold water in the water outlet of the ice tank and the hot water in the hot water outlet of the faucet from mixing. At the same time, the hot water outlet of the faucet formed by the water tank water circuit plate can further reduce the use of silicone tubes, reduce the number of parts, and facilitate assembly.

[0023] In one alternative implementation, the water tank includes:

[0024] The water tank body has an opening at the top, and the water circuit board is integrated with the water tank body.

[0025] The water tank cover is detachably installed at the opening of the water tank body.

[0026] Beneficial effects: The water tank body and water circuit board are integrated into one structure, and the water tank cover is detachably connected to the water tank body, facilitating the disassembly and maintenance of components on the water tank cover, as well as the cleaning of the inside of the water tank body. By integrating the water circuit board into the water tank body, the water path connecting the water tank to components such as the heating element and cooling element is shortened, which is more conducive to improving the space compactness of the drinking water equipment and the water dispensing speed.

[0027] In one optional embodiment, the water tank cover is provided with a vent, and the water tank water circuit board is also integrated with a vent pipe. One end of the vent pipe is connected to the ice bladder water outlet of the water tank water circuit board, and the other end is connected to the vent.

[0028] And / or, the water tank cover is provided with a float valve assembly and / or a level switch.

[0029] Beneficial effects: By setting the vent on the water tank cover and the vent pipe integrated on the water tank circuit board, when the chilled water system is cooling water, the room temperature air inside the cooling components will be discharged into the ice tank water outlet circuit and then discharged to the external environment through the vent pipe, ensuring the cooling effect, improving energy efficiency, and avoiding some potential operational problems of the chilled water system. Furthermore, by using a float valve assembly and a level switch installed on the tank cover, the float valve assembly can close the inlet when the water level in the tank reaches the set upper limit and open the inlet to replenish water when the water level drops, preventing the tank from running dry or overflowing. The level switch facilitates the detection of the water level in the tank. By assembling both the float valve assembly and the level switch on the tank cover, if the level switch or float valve assembly malfunctions, the user can directly remove the tank cover to inspect and maintain the level switch and float valve assembly, making maintenance and replacement of the float valve assembly and level switch convenient. Moreover, the tank cover, float valve assembly, and level switch can be pre-assembled into a single unit before being connected to the tank body, improving assembly efficiency.

[0030] Secondly, this utility model also provides a drinking water device, including a water tank module according to any of the above embodiments.

[0031] In one optional embodiment, the drinking water device further includes:

[0032] The water outlet has a cold water inlet, a hot water inlet, and a water outlet.

[0033] The chilled water system includes a chiller component, which has a chiller component inlet and a chiller component outlet. The chiller component inlet is connected to the ice bladder inlet water passage of the water tank water passage plate, and the chiller component outlet is connected to the cold water inlet of the outlet nozzle through the ice bladder outlet water passage of the water tank water passage plate.

[0034] The hot water system includes a hot water pipe connected to the first outlet of the water tank at the inlet end, a heating element installed on the hot water pipe, and a water pump, a heating element and a three-way solenoid valve connected in series along the water flow direction on the hot water pipe.

[0035] The three-way solenoid valve has an inlet, a first outlet, and a second outlet. The inlet of the three-way solenoid valve is connected to the outlet end of the hot water pipe. The first outlet is connected to the water outlet through the hot water pipe of the water tank circuit board. The second outlet is connected to the refrigeration unit through the circulating sterilization water pipe of the water tank circuit board.

[0036] Beneficial effects: The inlet of the three-way solenoid valve is sealed and plugged into the outlet of the hot water pipe. The first outlet of the three-way solenoid valve is suitable for sealing and plugging into the inlet end of the hot water pipe of the water tank circuit board. The second outlet of the three-way solenoid valve is suitable for sealing and plugging into the inlet end of the circulating sterilization water pipe of the water tank circuit board. The three-way solenoid valve can not only play the role of opening and closing the water pipe, but also play the role of connecting the water tank circuit board and the heating element, further reducing the use of silicone tubing.

[0069] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0070] The following is combined Figures 1 to 17 The following describes embodiments of the present invention.

[0071] According to an embodiment of the present invention, in one aspect, the present invention provides a water tank module for use in drinking water equipment. The drinking water equipment includes a hot water system, a cooling water system, and a water outlet. The water tank module includes a water tank 10 and a water tank water circuit board 110. The water tank 10 has a water storage chamber and a first water outlet 116 and a second water outlet 118. The first water outlet 116 is suitable for connecting to the hot water system, and the second water outlet 118 is suitable for connecting to the cooling water system. The water tank water circuit board 110 is integrated with the water tank 10. The water tank water circuit board 110 integrates water circuits for respectively connecting the water tank 10 to the cooling water system and / or, the cooling water system to the water outlet 50 and / or, the hot water system to the water outlet 50 and / or, and the hot water system to the cooling water system.

[0072] In the above embodiments, by adopting an integrated water tank 10 and water tank water circuit board 110, the step of separately disassembling and assembling the water tank water circuit board 110 is eliminated, improving the overall assembly efficiency. Furthermore, by integrating water circuits within the water tank water circuit board 110 to connect the water tank 10 with the cooling water system and / or, the cooling water system with the water outlet 50 and / or, the hot water system with the water outlet 50 and / or, and the hot water system with the cooling water system, the traditional silicone tube connection method is replaced. This integrates multiple water circuits into a single, efficient, and compact water tank water circuit board 110, achieving direct connection between the internal water circuits of the water tank 10, the hot water system, the cooling water system, and the water outlet 50. This not only simplifies the structure but also avoids the aging and odor problems of silicone tubes, as well as the problems of chaotic and unsafe water circuit systems. It improves the overall sealing, stability, and safety of the machine, solving the problems of numerous internal wiring and piping, complex assembly, low efficiency, easy aging, and high safety hazards in existing drinking water equipment. In addition, the water tank 10 and the water tank water circuit board 110 are assembled into a module, and multiple water circuits are integrated in the water tank water circuit board 110. This allows different functional modules to be flexibly combined as needed, greatly simplifying the assembly steps of the water circuit system, improving the production efficiency of the drinking water equipment, and also facilitating the later maintenance and upgrading of the drinking water equipment. This meets diverse needs while reducing production and maintenance costs.

[0073] Specifically, in this embodiment, the water tank 10 and the water tank water circuit board 110 are an integrated structure. The water tank water circuit board 110 integrates an ice tank inlet water circuit for connecting the water tank 10 with the chilled water system, and / or, the water tank water circuit board 110 integrates an ice tank outlet water circuit for connecting the chilled water system with the water outlet 50, and / or, the water tank water circuit board 110 integrates a hot water outlet water circuit for connecting the hot water system with the water outlet 50, and / or, the water tank water circuit board 110 integrates a hot water outlet water circuit for connecting the hot water system with the chilled water system. The water outlet 50 has a cold water inlet, a hot water inlet, and a water intake. The cold water inlet is connected to the chilled water system, the hot water inlet is connected to the hot water system, and the water intake is for users to take water.

[0074] Preferably, in this embodiment, the water dispenser is a pipeline machine; more preferably, it is a hot and cold water pipeline machine. This embodiment, through an innovative modular design integrating the water tank 10 and the water tank circuit board 110, improves the production efficiency of the water dispenser and reduces manufacturing costs, solving problems such as odor, complex assembly, and low reliability inherent in traditional pipeline machines that connect various water lines via silicone tubing.

[0075] In some embodiments, the water tank water circuit board 110 integrates an ice tank inlet water circuit 111, the inlet end of which is integrally connected to the second outlet 118, and the outlet end is connected to the inlet of the chilled water system; the water tank water circuit board 110 also integrates an ice tank outlet water circuit 112, the inlet end of which is connected to the outlet of the chilled water system, and the outlet end of which is connected to the cold water inlet of the outlet nozzle 50.

[0076] In the above embodiment, the water tank water circuit board 110 integrates a water circuit board body, and the water circuit board body integrates an ice tank water inlet water circuit 111. The inlet end of the ice tank water inlet water circuit 111 is integrally connected with the second outlet 118 of the water tank 10, and the outlet end of the ice tank water inlet water circuit 111 is connected to the inlet of the chilled water system to realize the supply of water to the chilled water system. Furthermore, the water circuit board body also integrates an ice tank water outlet water circuit 112. The inlet end of the ice tank water outlet water circuit 112 is connected to the outlet of the chilled water system, and the outlet end of the ice tank water outlet water circuit 112 is connected to the cold water inlet of the water outlet 50 to deliver the cold water prepared in the chilled water system to the water outlet 50 for user use. By integrating the ice tank inlet water passage 111 and ice tank outlet water passage 112 on the water tank water circuit board 110, the integration is high, which can reduce the number of parts and facilitate the assembly of the cooling water system with the water tank 10 and the water outlet 50.

[0077] Specifically, the water outlet 50 has a cold water inlet and a hot water inlet, and the outlet end of the ice tank water outlet passage 112 forms a first interface 1120 suitable for connection with the cold water inlet of the water outlet 50. Preferably, the water outlet also integrates a temperature sensor for monitoring the outlet water temperature. The chilled water system includes a chiller 30, which has a chiller inlet and a chiller outlet. The outlet end of the ice tank water inlet passage 111 is connected to the chiller inlet, and the inlet end of the ice tank water outlet passage 112 is connected to the chiller outlet.

[0078] In some embodiments, a first valve port is provided on the ice tank outlet water passage 112, and the water tank module also includes a cold water solenoid valve 80, which is installed on the first valve port and is used to control the on / off of the ice tank outlet water passage 112.

[0079] In the above embodiment, the water tank module also includes a cold water solenoid valve. The cold water solenoid valve facilitates the control of the opening and closing of the ice tank outlet water passage 112. By assembling the cold water solenoid valve 80, water tank 10, and water tank water passage plate 110 into a module, the assembly steps of the water system are greatly simplified, the production efficiency of the drinking water equipment is improved, and the later maintenance and upgrading of the drinking water equipment are also facilitated.

[0080] In some embodiments, the water tank water circuit board 110 also integrates a circulating sterilization water circuit 114, the inlet end of which is connected to the outlet end of the hot water system, and the outlet end is connected to the outlet of the cooling water system.

[0081] In the above embodiment, the circulating sterilization water path 114 integrated into the water tank water circuit board 110 is connected between the outlet of the hot water system and the outlet of the cooling water system. This independent circulating sterilization water path 114 allows the high-temperature hot water produced by the hot water system to be passed into the cooling water system for high-temperature sterilization, improving the hygiene performance and user experience of the drinking water equipment. Furthermore, the hot water system, circulating sterilization water path 114, cooling water system, and water tank 10 form a loop, enabling high-temperature circulating flushing and sterilization of the cooling water system, hot water system, and water tank 10, further improving the overall hygiene and cleanliness of the machine and ensuring water safety. In addition, the circulating sterilization water path 114 formed on the water tank water circuit board 110 further reduces the use of silicone tubing, resulting in a smaller number of silicone tubes and a neater, more aesthetically pleasing structure after assembly of the entire drinking water equipment.

[0082] Of course, in other alternative implementations, a switch valve can be installed on the ice tank inlet water passage 111. When the cooling water system is sterilized at high temperature, the switch valve is controlled to close the ice tank inlet water passage 111, so that hot water only flows into the cooling component 30 and does not flow into the water tank 10. After sterilization, the drain port on the cooling component 30 is opened to discharge the sterilized water.

[0083] In some embodiments, the inlet of the circulating sterilization water path 114 is connected to the outlet of the hot water system, and the outlet is connected to the outlet of the ice tank water path 112. The outlet of the circulating sterilization water path 114 is located between the cold water solenoid valve 80 on the ice tank outlet water path 112 and the outlet of the chilled water system, that is, the outlet of the circulating sterilization water path 114 is located upstream of the cold water solenoid valve. Specifically, the ice tank outlet water path 112 is provided with a circulating water inlet, which is located upstream of the cold water solenoid valve, that is, the circulating water inlet is located between the outlet of the hot water system and the cold water solenoid valve, and the outlet of the circulating sterilization water path 114 is connected to the circulating water inlet.

[0084] In the above embodiment, the outlet of the circulating sterilization water path 114 is located upstream of the cold water solenoid valve 80. Therefore, during the high-temperature sterilization and disinfection of the cooling water system of the drinking water equipment, the hot water generated by the hot water system will not flow through the cold water solenoid valve 80. On the one hand, this can reduce the damage of hot water to the cold water solenoid valve and reduce the phenomenon of damage to the cold water solenoid valve 80 due to the impact of high-temperature water and cold water. On the other hand, it reduces the retention of hot water in the cold water solenoid valve 80, which would cause the drinking water equipment to experience cross-temperature, improves the independence between the cold and hot water of the drinking water equipment, and avoids heat exchange between the cold and hot water systems of the drinking water equipment. Thus, while achieving efficient sterilization of the drinking water equipment, it maintains the temperature stability of the cold water system and the hot water system of the drinking water equipment.

[0085] In one specific embodiment, the cold water solenoid valve 80 is fixed to the water tank circuit board 110 by a pressure plate 90 and screws.

[0086] In one specific embodiment, the cold water solenoid valve 80 and the ice tank outlet water passage 112 are sealed by two O-rings 91.

[0087] In some embodiments, the water tank water circuit board 110 also integrates a hot water faucet circuit 113, the inlet end of which is connected to the outlet end of the hot water system, and the outlet end is connected to the hot water inlet of the outlet faucet 50.

[0088] In the above embodiment, the cold water inlet of the water outlet is connected to the ice tank water outlet passage 112, and the hot water inlet of the water outlet is connected to the hot water passage 113. Cold water and hot water flow through the ice tank water outlet passage 112 and the hot water passage 113 to the cold water inlet and hot water inlet of the water outlet 50, respectively. This can prevent the cold water in the ice tank water outlet passage 112 and the hot water in the hot water passage 113 from mixing. At the same time, the hot water passage 113 formed by the water tank water circuit plate 110 can further reduce the use of silicone tubes, reduce the number of parts, and facilitate assembly.

[0089] Specifically, the outlet end of the hot water circuit 113 of the faucet forms a second interface 1130 suitable for connecting with the hot water inlet of the faucet.

[0090] In some embodiments, the water tank 10 includes a water tank body 1001 with an opening at the top and a water storage cavity inside. A first water outlet 116 and a second water outlet 118 are formed on the water tank body 1001. A water tank water passage plate 110 is integrated with the water tank body 1001. Preferably, the water tank water passage plate 110 is integrally formed with the water tank body 1001. More preferably, the water tank water passage plate 110 is located below the water tank body 1001 to facilitate connection with a cooling water system located below the water tank 10. The water tank 10 also includes a water tank cover 1002, which is detachably installed at the opening of the water tank body 1001.

[0091] In the above embodiments, the water tank body 1001 and the water tank water circuit board 110 are an integral structure, and the water tank cover 1002 is detachably connected to the water tank body 1001, which facilitates the disassembly and maintenance of the components on the water tank cover 1002, as well as the cleaning of the inside of the water tank body 1001. By integrating the water tank water circuit board into the water tank body, the water connection between the water tank and components such as the heating element and the cooling element is shortened, which is more conducive to improving the space compactness of the drinking water equipment and the water output speed of the drinking water equipment.

[0092] Furthermore, the water tank cover 1002 is provided with an exhaust port; the water tank water circuit board 110 also integrates an exhaust pipe 115, one end of which is connected to the ice chamber water outlet 112 of the water tank water circuit board 110, and the other end is connected to the exhaust port. Through the exhaust port on the water tank cover and the exhaust pipe 115 integrated on the water tank water circuit board, when the chilled water system is cooling water, the ambient temperature air inside the cooling components is discharged into the ice chamber water outlet and then through the exhaust pipe 115 to the external environment, ensuring cooling effect, improving energy efficiency, and avoiding some potential operational problems of the chilled water system.

[0093] Specifically, the ice tank outlet water passage 112 includes a first cold water passage 1121 and a second cold water passage 1122. One end of the first cold water passage 1121 is connected to the outlet of the refrigeration component 30, and the other end is connected to the inlet of the cold water solenoid valve 80. One end of the second cold water passage 1122 is connected to the outlet of the cold water solenoid valve 80, and the other end is connected to the first interface 1120. The first interface 1120 is connected to the cold water inlet of the outlet nozzle 50. The vent pipe 115 is located inside the water tank body 1001. One end of the vent pipe 115 is connected to the first cold water passage, and the other end extends upward to a position higher than the highest water level of the water tank body 1001, so as to connect with the vent on the water tank cover 1002.

[0094] Furthermore, the water tank cover 1002 is provided with a water inlet, and the cover assembly also includes a float valve assembly 1003 and / or a level switch 1004 disposed on the water tank cover 1002. Specifically, the float valve assembly 1003 is located at the water inlet and can move up and down with the water level change in the water tank 10 to close or open the water inlet; the level switch 1004 is disposed on the water tank cover 1002 and is used to monitor the liquid level information in the water tank 10.

[0095] In the above embodiment, by providing an exhaust port on the water tank cover, when the cooling components of the cooling water system are sterilized at high temperature, the cold air inside the cooling components will enter the water tank along with the water flow when the hot water from the heating element enters the cooling components through the circulating sterilization water path. The exhaust port can then discharge the cold air to the external environment. Furthermore, by using the float valve assembly and level switch installed on the tank cover, the float valve assembly 1003 can close the inlet when the water level in the water tank 10 reaches the set upper limit water level, and open the inlet to replenish water when the water level drops, preventing the water tank 10 from running out of water or overflowing. The level switch 1004 is designed to facilitate the detection of the water level in the water tank 10. By assembling both the float valve assembly 1003 and the level switch 1004 on the water tank cover 1002, if the level switch and float valve assembly malfunction, the user can directly remove the water tank cover to inspect and maintain the level switch and float valve assembly. This not only facilitates the maintenance and replacement of the float valve assembly 1003 and the level switch 1004, but also allows the water tank cover 1002, the float valve assembly 1003, and the level switch 1004 to be assembled into a whole before being connected to the water tank body 1001, which can improve assembly efficiency.

[0096] In some embodiments, the water tank 10 includes an ultraviolet sterilization device 1005, which is disposed inside the water tank 10 and is used to sterilize the water in the water storage chamber with ultraviolet light.

[0097] In the above embodiment, the ultraviolet sterilization device 1005 installed in the water tank 10 can sterilize the water in the water tank 10 and prevent bacteria from growing in the water inside the water tank 10.

[0098] Preferably, the ultraviolet sterilization device 1005 is installed on the bottom wall of the water tank 10, and the ultraviolet sterilization device 1005 includes an ultraviolet lamp. (In conjunction with...) Figure 1 , Figure 11 , Figure 17 As shown, the water tank body 1001 is provided with an ultraviolet lamp mounting port 119 for installing the ultraviolet sterilization device 1005.

[0099] According to an embodiment of the present invention, in another aspect, a drinking water device is provided, including a water tank module of any of the above embodiments.

[0100] In some embodiments, the drinking water equipment further includes a water outlet 50, a cooling water system, and a hot water system. The water outlet 50 has a cold water inlet, a hot water inlet, and a water intake.

[0101] Furthermore, the chilled water system includes a chiller 30, which has a chiller inlet and a chiller outlet. The chiller inlet is connected to the ice tank inlet water passage 111 of the water tank water circuit board 110, and the chiller outlet is connected to the cold water inlet of the outlet nozzle 50 through the ice tank outlet water passage 112 of the water tank water circuit board 110. A circulating sterilization water passage 114 connects the hot water system and the chiller 30. Preferably, the chiller 30 is an electronic ice tank.

[0102] Furthermore, the hot water system includes a hot water pipe connected at its inlet end to the first outlet 116 of the water tank 10, and a water pump 70, a heating element 20, and a three-way solenoid valve 40 connected in series along the water flow direction on the hot water pipe.

[0103] Furthermore, the circulating sterilization water circuit 114 is connected between the three-way solenoid valve 40 and the refrigeration unit 30. The three-way solenoid valve 40 has an inlet, a first outlet, and a second outlet. The inlet of the three-way solenoid valve 40 is connected to the outlet end of the hot water pipe. The first outlet is connected to the water outlet 50 through the hot water circuit 113 of the water tank circuit board 110. The second outlet is connected to the refrigeration unit 30 through the circulating sterilization water circuit 114 of the water tank circuit board 110.

[0104] Specifically, the inlet end of the hot water pipe is connected to the first outlet 116, and the outlet end is connected to the inlet of the three-way solenoid valve 40. The inlet end of the hot water pipe 113 of the first outlet water tank water circuit board 110 of the three-way solenoid valve 40 is connected to the water tap, thereby realizing the connection between the hot water system and the outlet 50.

[0105] In the above embodiment, the inlet of the three-way solenoid valve 40 is sealed and plugged into the outlet of the hot water pipe. The first outlet of the three-way solenoid valve 40 is suitable for sealing and plugging into the inlet end of the hot water pipe 113 of the water tank water circuit board 110. The second outlet of the three-way solenoid valve 40 is suitable for sealing and plugging into the inlet end of the circulating sterilization water pipe 114 of the water tank water circuit board 110. The three-way solenoid valve 40 can not only play the role of opening and closing the water circuit, but also play the role of connecting the water tank water circuit board 110 and the heating element 20, further reducing the use of silicone tubes.

[0106] In some embodiments, sealing sleeves 410 are provided on the outer side of the inlet of the three-way solenoid valve 40, the outer side of the first outlet of the three-way solenoid valve 40, and the outer side of the second outlet of the three-way solenoid valve 40. The inlet of the three-way solenoid valve 40 is inserted into the outlet of the hot water pipe, the first outlet of the three-way solenoid valve 40 is inserted into the hot water pipe 113 of the faucet, and the second outlet of the three-way solenoid valve 40 is inserted into the circulating sterilization water pipe 114.

[0107] In some embodiments, the refrigeration component 30 is located below the water tank module. The outlet end of the ice tank inlet water passage 111 is located below the water tank water circuit board 110 and is adapted to be directly opposite the inlet of the refrigeration component. The inlet end of the ice tank outlet water passage 112 is located below the water tank water circuit board 110 and is adapted to be directly opposite the outlet of the refrigeration component. This design facilitates the connection between the ice tank inlet water passage 111 and the refrigeration component inlet, and between the ice tank outlet water passage 112 and the refrigeration component outlet, eliminating the need for connecting pipes, simplifying assembly, and improving the assembly efficiency of the drinking water equipment.

[0108] In some embodiments, the hot water supply system includes a first pipe connecting the first outlet 116 of the water tank 10 and the water pump 70. The first outlet 116 is located at the lower end of the water tank 10 and is connected to an L-shaped adapter 117. Since a cooling component 30 is located below the water tank 10, connecting the first outlet 116 to the L-shaped adapter 117 allows adjustment of the position of the first pipe, preventing interference with the cooling component 30. The hot water supply system also includes a second pipe connecting the water pump 70 and the heating element 20, and a third pipe 211 connecting the heating element 20 and the three-way solenoid valve 40.

[0109] In some embodiments, the drinking water equipment further includes a water circuit board assembly, which includes a water tank module and an upper water circuit board module. The upper water circuit board module includes an upper water circuit board 210 and a three-way solenoid valve 40. The upper water circuit board 210 is integrally formed with an upper water circuit and a third pipe 211. The inlet of the upper water circuit is adapted to connect to an external water source inlet pipe 101, and the outlet of the upper water circuit is adapted to connect to the inlet of the water tank 10. The inlet of the third pipe 211 is adapted to connect to the outlet of the heating element 20, and the outlet is connected to the inlet of the three-way solenoid valve 40. The upper water circuit board module also includes an inlet solenoid valve 60, which is located in the upper water circuit.

[0110] In the above embodiment, the inlet solenoid valve 60, the three-way solenoid valve 40 and the water supply board 210 are assembled into a module, which greatly simplifies the assembly steps of the water system, improves the production efficiency of the drinking water equipment, and also facilitates the later maintenance and upgrading of the drinking water equipment.

[0111] In some embodiments, the water tank water circuit board 110 module is disposed above the cooling component 30, and the upper water circuit board module is disposed on one side of the cooling component 30. The water tank water circuit board 110 module being disposed above the cooling component 30 and the upper water circuit board module being disposed on one side of the cooling component 30 results in a compact layout and facilitates the connection between the water tank water circuit board 110 and the cooling component 30. Furthermore, the modular design of the drinking water equipment in this embodiment eliminates the need for silicone tube connections between various water circuit functional units, thus avoiding the traditional silicone tube connection method and solving the technical problems of traditional silicone tubes aging easily after prolonged use, producing odors, and affecting drinking water quality.

[0112] In some embodiments, the drinking water equipment further includes a drain plate 310, on which the cooling component 30 and the heating element 20 are disposed. The drain plate 310 is used to support the cooling component 30 and the heating element 20, and to connect the water tank 10 and the heating element 20.

[0113] In this embodiment of the drinking water device, the water flow path when hot water is dispensed is: water tank 10 → water pump 70 → heating element 20 → three-way solenoid valve 40 (first outlet) → water outlet. The three-way solenoid valve 40 is in its first operating state.

[0114] The water flow path when drawing cold water is as follows: water tank 10 → cooling component 30 → cold water solenoid valve 80 → water outlet. The water level in water tank 10 is higher than the height of cooling component 30 and the water outlet. When the user draws cold water, the cold water solenoid valve 80 opens, and the water flows out naturally under gravity.

[0115] High-temperature circulating sterilization process: Water tank 10 → Water pump 70 → Heating element 20 → Three-way solenoid valve 40 (second outlet) → Refrigeration component 30 → Water tank 10. Among them, the three-way solenoid valve 40 is in the second working state.

[0116] In one specific embodiment, the drinking water equipment is a pipeline machine.

[0117] This application's embodiments, by adopting an integrated water circuit board module and a modular design concept, solve the problems of odor, complex assembly, and low reliability inherent in traditional drinking water equipment. The integrated water circuit board module not only improves the system sealing and stability of the drinking water equipment but also simplifies the assembly process, increasing production efficiency. The modular design of the drinking water equipment makes maintenance and upgrades more convenient, significantly improving the overall performance and user experience. This not only enhances product quality but also reduces production costs, strengthening the product's market competitiveness.

[0118] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
