Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, specifically to a water supply circuit board module and drinking water equipment. Background Technology

[0002] Currently, household water dispensers mainly consist of a water tank, controller module, heating element, ice tank, water pump, solenoid valve, and water system. When a user needs hot water, the water in the tank is pumped through the drain pipe to the heating element, where it is heated to boiling and then flows out from the heating element's outlet. After passing through the solenoid valve, it flows through the tap for the user to drink. When a user needs cold water, the cold water in the ice tank flows through the cold water outlet solenoid valve and then through the tap for the user to drink. When a user needs boiled water, the water pump pumps the water in the tank to the heating element to boil it. The boiled water then flows through the heat exchanger, where heat exchange occurs, cooling the water to the user's desired temperature before it flows through the tap for the user to drink.

[0003] Currently, many water systems in water dispensers are made by connecting silicone tubes, stainless steel tubes, PE tubes, etc., with various joints. Water systems made with silicone tubes leave a silicone tube taste in the water after boiling water flows through them, which is a pain point for users. Secondly, water systems made with silicone tubes, stainless steel tubes, PE tubes, etc., are also relatively messy inside the product. Because these water systems have many bends or uneven surfaces, they are prone to problems such as air trapping in the water system, resulting in poor water flow and affecting functionality or user experience.

[0064] Currently, many water systems in water dispensers are made by connecting silicone tubes, stainless steel tubes, PE tubes, etc., with various joints. Water systems made with silicone tubes leave a silicone tube taste in the water after boiling water flows through them, which is a pain point for users. Secondly, water systems made with silicone tubes, stainless steel tubes, PE tubes, etc., are also relatively messy inside the product.

[0102] Specifically, when the user needs to connect to cold water, the chilled water solenoid valve 80 opens, such as... Figure 13 As shown, water in water tank 10 enters the ice tank through the ice tank inlet water passage 111 in the water tank water circuit board 110. After being cooled by the ice tank, it flows through the ice tank outlet water passage 112 to the cold water inlet interface 1151 of the outlet, and finally flows out through the outlet 50 for drinking. When the user needs hot water, such as... Figure 14 As shown, the hot water heated by the heating element 20 flows to the water outlet 211 of the heating element, then flows through the first outlet of the three-way solenoid valve 40 to the hot water outlet 113 in the water tank water circuit board 110, then flows to the hot water inlet interface 1152 of the water outlet, and finally flows out through the water outlet 50 for the user to drink.

[0103] In one embodiment, the water tank water circuit board 110 is formed with an inlet interface 118 and an outlet interface 119 of an ice water solenoid valve. The ice tank water outlet circuit 112 includes a first pipe section 1121 and a water tap cold water circuit 115. The first end of the first pipe section 1121 is adapted to be directly opposite the outlet of the refrigeration component 30. The second end of the first pipe section 1121 is connected to the inlet interface 118 of the ice water solenoid valve. The first end of the water tap cold water circuit 115 is connected to the outlet interface 119 of the ice water solenoid valve. The second end of the water tap cold water circuit 115 is connected to the outlet cold water inlet interface 1151 of the water tap.

[0104] In this embodiment, the ice water solenoid valve inlet interface 118 and ice water solenoid valve outlet interface 119 are formed in the water tank water circuit plate 110, which facilitates the quick positioning and installation of the ice water solenoid valve 80.

[0105] In one embodiment, the water tank 10 is provided with an exhaust port 1006, and the water tank water circuit board 110 is formed with an exhaust pipe 120. One end of the exhaust pipe 120 is connected to the first pipe section 1121, and the other end is connected to the exhaust port 1006.

[0106] In this embodiment, since air is present after the water passes through the cooling element 30, it is necessary to vent the air to maintain the pressure balance within the pipeline. This is achieved by providing an vent 1006 in the water tank 10 and forming an vent pipe 120 in the water tank water circuit board 110. One end of the vent pipe 120 is connected to the first pipe section 1121, and the other end is connected to the vent 1006, allowing for timely removal of air from the water flowing out of the cooling element 30. Furthermore, the vent pipe 120 in the water tank water circuit board 110 enhances its integration, reducing the use of silicone tubing. This not only avoids the aging and odor problems associated with silicone tubing but also improves the overall system's sealing and stability, preventing water system chaos and safety issues.

[0107] In one specific embodiment, the vent 1006 is located on the water tank cover 1002.

[0108] In one embodiment, the side wall of the first pipe section 1121 is provided with an opening 11211, and the circulating sterilization water path 114 is connected to the first pipe section 1121 through the opening 11211. The opening 11211 is lower than the inlet interface 118 of the ice water solenoid valve.

[0109] In this embodiment, by providing an opening 11211 on the side wall of the first pipe section 1121, it is convenient to connect the circulating sterilization water path 114 with the ice tank outlet water path 112. Furthermore, the opening 11211 is lower than the inlet interface 118 of the ice water solenoid valve. Therefore, when the high-temperature water in the circulating sterilization water path 114 enters the first pipe section 1121, it will flow into the interior of the refrigeration component 30 under the action of gravity.

[0110] In one embodiment, the water tank 10 has a drain outlet 116, which is adapted to be connected to the water pump 70 via a drain pipe 103.

[0111] In one embodiment, the drain outlet 116 is located at the lower end of the water tank 10, and the drain outlet 116 is connected to an L-shaped adapter 117, which is connected to the drain pipe 103.

[0112] Specifically, the upper end of the drain pipe 103 is connected to the drain outlet 116 of the water tank 10 via an L-shaped adapter 117, and the lower end of the drain pipe 103 is connected to the drain circuit board 310 via a quick connector, thus realizing the water passage from the water tank 10 to the drain circuit board 310. The water from the water tank 10 to the drain circuit board 310 is pumped by the water pump 70 to the inlet end of the heating element 20 of the drain circuit board 310, thus realizing the water tank 10 supplying water to the heating element 20. The water flows out from the outlet end of the heating element 20 and enters the upper water circuit board 210. The water flowing out from the upper water circuit board 210 passes through the three-way solenoid valve 40 (one inlet, two outlets). Then, the water flows out from the first outlet of the three-way solenoid valve 40 and enters the hot water circuit 113 of the water tank circuit board 110, and finally flows out from the outlet 50 for user use; the water flows out from the second outlet of the three-way solenoid valve 40 and enters the circulating sterilization water circuit 114 in the water tank circuit board 110, then flows to the ice tank outlet water circuit 112, then enters the refrigeration component 30, and then flows out from the refrigeration component 30, and flows into the water tank 10 through the ice tank inlet water circuit 111, realizing the circulation of water from the water tank 10 and back to the water tank 10, and achieving the effect of high-temperature circulating sterilization after multiple cycles.

[0113] In one embodiment, the water tank 10 includes a water tank body 1001 and a water tank cover assembly. The water tank body 1001 and the water tank water circuit board 110 are integral structures, and the water tank cover assembly is detachably connected to the water tank body 1001.

[0114] In one embodiment, the water tank cover assembly includes a water tank cover 1002, a float valve assembly 1003, and a level switch 1004. The water tank cover 1002 is detachably connected to the water tank body 1001, the float valve assembly 1003 is disposed on the water tank cover 1002, and the level switch 1004 is disposed on the water tank cover 1002.

[0115] In one embodiment, the water tank 10 is provided with an ultraviolet lamp assembly 1005.

[0116] Specifically in one embodiment, such as Figure 11 As shown, the water tank body 1001 is formed with a UV lamp mounting port 1007, which facilitates fixing the UV lamp assembly 1005 to the water tank body 1001.

[0117] 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.

[0118] 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.

[0119] The water flow path when taking cold water is: water tank 10 → refrigeration unit 30 → ice water solenoid valve 80 → water outlet 50. Among them, the water level in water tank 10 is higher than the height of refrigeration unit 30 and water outlet 50. When the user takes ice water, the ice water solenoid valve 80 is opened, and the water flows out naturally under the action of gravity.

[0120] 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.

[0121] In one specific embodiment, the drinking water equipment is a pipeline machine.

[0122] 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.

[0123] 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 scope defined by this application.
