Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to 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 connect the water and gas circuits, making the internal water and gas wiring more complex. This not only increases assembly complexity and the risk of omissions or incorrect installations, 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 affect product reliability and lifespan, and interference between the gas and water circuits can also occur. Utility Model Content

[0003] In view of this, the present invention provides a drinking water device to solve the problems of existing drinking water devices having many internal wiring pipes, complex assembly, low efficiency, easy aging and interference between each other, and high safety hazards.

[0004] In a first aspect, this utility model provides a drinking water device, comprising: a water tank, the water tank having a water storage chamber and a water tank vent pipe; a water tank water circuit board, the water tank water circuit board being integrated with the water tank, the water tank water circuit board having an ice tank inlet water circuit and an ice tank outlet water circuit for connecting the water storage chamber, and an vent pipe for connecting the water tank vent pipe; and a refrigeration component, the refrigeration component having an ice tank inlet water port, an ice tank outlet water port and an ice tank vent port, the ice tank inlet water port being configured to connect with the ice tank inlet water circuit, the ice tank outlet water port being configured to connect with the ice tank outlet water circuit, and the ice tank vent port being configured to connect with the vent pipe. Beneficial Effects: By assembling the water tank and water tank circuit board into a single module, and integrating independently configured vent pipes and multiple water passages within the water tank circuit board, this not only replaces the traditional silicone tubing connection method, simplifying the assembly steps of the piping system, but also reduces interference between the water and air passages. It achieves direct connection between the water tank and the internal water and air passages of the refrigeration components, simplifying the structure and avoiding the aging and odor problems associated with silicone tubing, as well as the confusion and safety issues of the water and air systems. This 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, assembling the water tank and water tank circuit board into a single module, and integrating multiple water and air passages within the water tank circuit board, allows for flexible combination of different functional modules as needed. This greatly simplifies the assembly steps of the water and air systems, improves the production efficiency of the drinking water equipment, and facilitates later maintenance and upgrades, meeting diverse needs while reducing production and maintenance costs.

[0005] In one alternative embodiment, the water tank includes: a water tank body with a top opening, and a water tank water circuit board integrated with the water tank body; and a water tank cover, which is detachably installed at the opening of the water tank body.

[0006] 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.

[0007] In one alternative embodiment, the water tank cover is provided with an exhaust port, one end of the water tank exhaust pipe is connected to the exhaust pipe, and the other end of the water tank exhaust pipe is connected to the exhaust port.

[0008] 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 from the ice tank vent and then through the vent pipe and the water tank vent pipe to the external environment, ensuring the cooling effect, improving energy efficiency, and avoiding some potential operational problems of the chilled water system.

[0009] In one optional embodiment, the water tank exhaust pipe is vertically disposed on the inner side wall of the water tank body, and the exhaust pipe is vertically connected to the bottom of the water tank body. The water tank also includes a connecting pipe horizontally disposed at the bottom of the water tank body and connecting the water tank exhaust pipe and the exhaust pipe.

[0010] Beneficial effects: By rationally arranging the positions of the water tank exhaust pipe, vent pipe, and connecting pipe, it is possible not only to reduce the impact of the water tank exhaust pipe on the water storage chamber and various components within the water storage chamber, but also to achieve a centered placement of the water tank and refrigeration components, thereby reducing the space occupied by the water tank and refrigeration components.

[0011] In one optional embodiment, the water tank has a first outlet and a second outlet, wherein the first outlet is adapted to be connected to the hot water system of the drinking water equipment, the second outlet is adapted to be connected to the cooling water system of the drinking water equipment, the inlet end of the ice tank inlet water passage is integrally connected to the second outlet, and the outlet end is connected to the ice tank inlet water passage; the inlet end of the ice tank outlet water passage is connected to the ice tank outlet water passage, and the outlet end is connected to the cold water inlet of the drinking water equipment's outlet.

[0012] Beneficial effects: The water tank is connected to the hot water system and the cooling water system through the first and second water outlets respectively, which not only improves the multi-functionality of the drinking water equipment, but also realizes the integrated setting of the water tank with the hot water system and the cooling water system.

[0013] Specifically, the water tank's water circuit board integrates a main body, on which an ice chamber inlet water circuit is integrated. The inlet end of the ice chamber inlet water circuit is integrated with the second outlet of the water tank, and the outlet end of the ice chamber inlet water circuit is connected to the ice chamber inlet, thus supplying water to the chilled water system. Furthermore, the main body of the water circuit board also integrates an ice chamber outlet water circuit. The inlet end of the ice chamber outlet water circuit is connected to the ice chamber outlet, and the outlet end of the ice chamber outlet water circuit is connected to the cold water inlet of the water outlet, thus delivering the chilled water prepared in the chilled water system to the water outlet for user use.

[0014] In one optional embodiment, a first valve is provided on the water outlet of the ice tank, and the water tank includes: 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.

[0015] Beneficial effects: The cold water solenoid valve allows for convenient control of the on / off flow of the ice tank outlet. By assembling the cold water solenoid valve, water tank, and water tank circuit board into a single module, the assembly steps of the water system are greatly simplified, improving the production efficiency of the drinking water equipment. It also facilitates the later maintenance and upgrades of the drinking water equipment.

[0016] In one alternative implementation, the water tank circuit board integrates: 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 implementation, 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 and the ice tank outlet on the ice tank outlet water path.

[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: 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. 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.

[0021] In one optional embodiment, the drinking water equipment further includes a hot water production pipeline connected to the first outlet of the water tank at the inlet end, a heating element disposed on the hot water production pipeline, 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 production pipeline. 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.

[0022] Beneficial effects: The three-way solenoid valve enables water dispensers to switch between hot water production mode and high-temperature sterilization mode, thereby realizing the hot water production and high-temperature sterilization operations of the water dispensers. Moreover, the three-way solenoid valve can not only open and close the water circuit, but also connect the water tank circuit board and the heating element, further reducing the use of silicone tubing.

[0023] Specifically, 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, and 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.

[0030] 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.

[0031] The following is combined Figures 1 to 15 The following describes embodiments of the present invention.

[0032] like Figures 1 to 4As shown, according to an embodiment of the present invention, in one aspect, the present invention provides a drinking water device, which includes: a water tank 10, the water tank 10 being provided with a water storage chamber and a water tank exhaust pipe 1006; a water tank water circuit board 110, the water tank water circuit board 110 being integrated with the water tank 10, the water tank water circuit board 110 being integrated with an ice tank inlet water circuit 111 and an ice tank outlet water circuit 112 for connecting the water storage chamber, and an exhaust pipe 115 connecting the water tank exhaust pipe 1006; and a refrigeration component 30, the refrigeration component 30 being provided with an ice tank inlet 301, an ice tank outlet 302 and an ice tank exhaust port 303, the ice tank inlet 301 being configured to connect with the ice tank inlet water circuit 111, the ice tank outlet 302 being configured to connect with the ice tank outlet water circuit 112, and the ice tank exhaust port 303 being configured to connect with the exhaust pipe 115.

[0033] In the above embodiments, by assembling the water tank 10 and the water tank water circuit board 110 into a module, and integrating independently configured exhaust pipes 115 and multiple water circuits within the water tank water circuit board 110, not only can the traditional silicone tube connection method be replaced, simplifying the assembly steps of the pipeline system, but also reducing interference between the water circuit and the air circuit. This achieves direct connection between the water tank 10 and the internal water circuit and air circuit of the cooling component 30, which not only simplifies the structure but also avoids the aging and odor of silicone tubes, as well as the problems of confusion and unsafety in the water circuit system and the air circuit system. It improves the sealing, stability and safety of the whole machine and solves the problems of numerous internal wiring pipelines, complex assembly, low efficiency, easy aging, and high safety hazards in the existing drinking water equipment.

[0034] In addition, the water tank 10 and the water tank water circuit board 110 are assembled into a module, and multiple water circuits and air 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 and the air 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.

[0035] 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 111 for connecting the water tank 10 with the chilled water system, and / or, an ice tank outlet water circuit 112 for connecting the chilled water system with the water outlet 50, and / or, a hot water circuit 113 for connecting the hot water system with the water outlet 50, and / or, a hot water circuit 113 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.

[0036] 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.

[0037] like Figures 5 to 7 As shown, in some embodiments, the water tank 10 includes: a water tank body 1001 with a top opening, a water tank water circuit board 110 integrated with the water tank body 1001; and a water tank cover 1002, which is detachably installed at the opening of the water tank body 1001.

[0038] In the above embodiment, the water tank water circuit board 110 is located below the water tank body 1001, facilitating connection with the cooling water system located below the water tank 10. 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, facilitating the disassembly and maintenance of components on the water tank cover 1002, as well as the cleaning of the interior of the water tank body 1001. By integrating the water tank water circuit board 110 into the water tank body 1001, the water path connecting the water tank 10 and components such as the cooling element 30 is shortened, which is more conducive to improving the space compactness of the drinking water equipment and the water dispensing speed of the drinking water equipment.

[0039] like Figures 1 to 4 As shown, in one optional embodiment, the water tank cover 1002 is provided with an exhaust port 1007, one end of the water tank exhaust pipe 1006 is connected to the exhaust pipe 115, and the other end of the water tank exhaust pipe 1006 is connected to the exhaust port 1007.

[0040] In the above embodiment, the water tank cover 1002 is provided with an exhaust port 1007; 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 1007. Through the exhaust port 1007 provided on the water tank cover 1002 and the exhaust pipe 115 integrated on the water tank water circuit board 110, when the chilled water system is cooling water, the ambient temperature air inside the cooling component 30 will be discharged from the ice chamber exhaust port 303 and then through the exhaust pipe 115 and the water tank exhaust pipe 1006, and finally discharged to the external environment from the exhaust port 1007, ensuring the cooling effect, improving energy efficiency, and avoiding some potential operational problems of the chilled water system.

[0041] 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 the float valve assembly 1003 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.

[0042] In the above embodiment, through the vent 1007 provided on the water tank cover 1002, when the cooling component 30 of the cooling water system is sterilized at high temperature, the cold air inside the cooling component 30 will enter the water tank 10 along with the water flow when the hot water from the heating element 20 enters the cooling component 30 through the circulating sterilization water path 114. The vent 1007 allows this cold air to be discharged to the external environment. Furthermore, through the float valve assembly 1003 and the level switch 1004 provided 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, and open the inlet to replenish water when the water level drops, preventing the water tank 10 from running dry or overflowing. The level switch 1004 facilitates 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 1004... If the float valve assembly 1003 malfunctions, the user can directly remove the water tank cover 1002 to inspect and maintain the level switch 1004 and the float valve assembly 1003. 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 pre-assembled into a single unit before being connected to the water tank body 1001, thus improving assembly efficiency.

[0043] like Figures 1 to 4 As shown, in one optional embodiment, the water tank exhaust pipe 1006 is vertically disposed on the inner side wall of the water tank body 1001, and the exhaust pipe 115 is vertically connected to the bottom of the water tank body 1001. The water tank 10 also includes a connecting pipe 1008 horizontally disposed at the bottom of the water tank body 1001 and connecting the water tank exhaust pipe 1006 and the exhaust pipe 115.

[0044] In the above embodiments, by reasonably arranging the positions of the water tank exhaust pipe 1006, exhaust pipe 115 and connecting pipe 1008, it is possible not only to reduce the impact of the water tank exhaust pipe 1006 on the water storage chamber and the various components inside the water storage chamber, but also to achieve the central setting of the water tank 10 and the cooling component 30, thereby reducing the space occupied by the water tank 10 and the cooling component 30.

[0045] like Figures 1 to 4As shown, in some embodiments, the water tank 10 has a first outlet 116 and a second outlet 118. The first outlet 116 is adapted to be connected to the hot water system of the drinking water equipment, and the second outlet 118 is adapted to be connected to the cooling water system of the drinking water equipment. The inlet end of the ice tank inlet water passage 111 is integrally connected to the second outlet 118, and the outlet end is connected to the ice tank inlet 301. The inlet end of the ice tank outlet water passage 112 is connected to the ice tank outlet 302. The interior of the refrigeration component 30 is provided with an ice tank outlet pipe 3021, which extends to the bottom of the refrigeration component 30 for absorbing ice water from the bottom of the refrigeration component 30. The outlet end is connected to the cold water inlet of the water outlet 50 of the drinking water equipment.

[0046] In the above embodiment, the water tank 10 is connected to the hot water system and the cooling water system through the first water outlet 116 and the second water outlet 118 respectively. This not only improves the multi-functionality of the drinking water equipment, but also realizes the integrated setup of the water tank 10 with the hot water system and the cooling water system.

[0047] Specifically, the water tank water circuit board 110 integrates a water circuit board body, on which an ice tank inlet water circuit 111 is integrated. The inlet end of the ice tank inlet water circuit 111 is integrally connected to the second outlet 118 of the water tank 10, and the outlet end of the ice tank inlet water circuit 111 is connected to the ice tank inlet 301 to deliver water to the chilled water system. Furthermore, the water circuit board body also integrates an ice tank outlet water circuit 112. The inlet end of the ice tank outlet water circuit 112 is connected to the ice tank inlet 301, and the outlet end of the ice tank outlet water circuit 112 is connected to the cold water inlet of the outlet 50 to deliver the cold water prepared in the chilled water system to the 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.

[0048] 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 50 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.

[0049] like Figures 5 to 7As shown, in some embodiments, a first valve port is provided on the ice tank outlet water passage 112, and the water tank 10 module also includes a cold water solenoid valve 80, which is installed on the first valve port and used to control the opening and closing of the ice tank outlet water passage 112.

[0050] In the above embodiment, the cold water solenoid valve 80 is set to facilitate the control of the opening and closing of the ice tank water outlet 112. By assembling the cold water solenoid valve 80, water tank 10, and water tank water circuit board 110 into a module, the assembly steps of the water circuit 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 convenient.

[0051] 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 1121, 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 1007 on the water tank cover 1002.

[0052] like Figures 8 to 11 As shown, in some embodiments, the water tank water circuit board 110 also integrates a circulating sterilization water circuit 114. The inlet end of the circulating sterilization water circuit 114 is connected to the outlet end of the hot water system, and the outlet end is connected to the outlet 302 of the ice tank.

[0053] 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.

[0054] 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.

[0055] like Figures 11 to 15 As shown, 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 ice tank outlet 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 cooling water system, that is, 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 ice tank outlet 302. 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 80, that is, the circulating water inlet is located between the outlet of the hot water system and the cold water solenoid valve 80, and the outlet of the circulating sterilization water path 114 is connected to the circulating water inlet.

[0056] 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 80 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.

[0057] 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.

[0058] 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.

[0059] like Figures 11 to 15 As shown, in some embodiments, the water tank water circuit board 110 also integrates a hot water faucet circuit 113. The inlet end of the hot water faucet circuit 113 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. In the above embodiment, the cold water inlet of the water outlet 50 is connected to the ice tank water outlet passage 112, and the hot water inlet of the water outlet 50 is connected to the hot water faucet passage 113. Cold water and hot water flow to the cold water inlet and hot water inlet of the water outlet 50 respectively through the ice tank water outlet passage 112 and the hot water faucet passage 113. This can prevent the cold water in the ice tank water outlet passage 112 and the hot water in the hot water faucet passage 113 from mixing. At the same time, the hot water faucet 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.

[0060] Specifically, the outlet end of the hot water path 113 of the faucet forms a second interface 1130 suitable for connection with the hot water inlet of the outlet 50.

[0061] like Figures 5 to 7 As shown, 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.

[0062] 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.

[0063] 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. The water tank body 1001 is provided with an ultraviolet lamp mounting port 119 for installing the ultraviolet sterilization device 1005.

[0064] like Figures 11 to 15 As shown, in some embodiments, the drinking water equipment also includes a hot water pipe connected to the first outlet 116 of the water tank 10 at its inlet end, 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; the three-way solenoid valve 40 has an inlet, a first outlet and a second outlet, wherein 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 pipe 113 of the water tank water circuit board 110, and the second outlet is connected to the cooling element 30 through the circulating sterilization water pipe 114 of the water tank water circuit board 110.

[0065] In the above embodiment, the cooling water system includes a cooling component 30, which has a cooling component 30 inlet and a cooling component 30 outlet. The cooling component 30 inlet is connected to the ice tank inlet water passage 111 of the water tank water circuit board 110, and the cooling component 30 outlet is connected to the cold water inlet of the water outlet 50 through the ice tank outlet water passage 112 of the water tank water circuit board 110. A circulating sterilization water passage 114 is connected between the hot water system and the cooling component 30. Preferably, the cooling component 30 is an electronic ice tank.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] In some embodiments, sealing sleeves 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.

[0071] In some embodiments, the refrigeration component 30 is located below the water tank 10 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 30. 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 30. This design facilitates the connection between the ice tank inlet water passage 111 and the inlet of the refrigeration component 30, and facilitates the connection between the ice tank outlet water passage 112 and the outlet of the refrigeration component 30, eliminating the need for connecting pipes, simplifying assembly, and improving the assembly efficiency of the drinking water equipment.

[0072] 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.

[0073] like Figures 7 to 10 As shown, in some embodiments, the drinking water device further includes a water circuit board assembly, which includes a water tank 10 module and an upper water circuit board 210 module. The upper water circuit board 210 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 water 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 210 module also includes an inlet solenoid valve 60, which is located in the upper water circuit.

[0074] 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.

[0075] like Figures 11 to 15 As shown, in some embodiments, the water tank water circuit board 110 module is located above the cooling component 30, and the upper water circuit board 210 module is located on one side of the cooling component 30. This compact layout 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 tubing connections between different water circuit functional units, thus solving the technical problems of traditional silicone tubing aging, odor generation, and impact on drinking water quality after prolonged use.

[0076] like Figure 1 , Figure 9 and Figure 10 As shown, in some embodiments, the drinking water device 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.

[0077] 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 50. Among them, the three-way solenoid valve 40 is in the first working state.

[0078] The water flow path when taking cold water is as follows: water tank 10 → cooling component 30 → cold water solenoid valve 80 → water outlet 50. The water level in the water tank 10 is higher than the height of the cooling component 30 and the water outlet 50. When the user takes cold water, the cold water solenoid valve 80 opens, and the water flows out naturally under the action of gravity.

[0079] 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.

[0080] In one specific embodiment, the drinking water equipment is a pipeline machine.

[0081] 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.

[0082] 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.
