Description

Technical Field

[0001] This invention relates to the field of drinking water equipment technology, specifically to water circuit board assemblies 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. Summary of the Invention

[0004] In view of this, the present invention provides a water circuit board assembly and a drinking water device to solve the problems of chaotic and unsafe water circuit systems in existing pipeline machines.

[0005] In a first aspect, the present invention provides a water circuit board assembly, comprising: a water tank water circuit board module and an upper water circuit board module, wherein the water tank water circuit board module comprises:

[0006] Water tank, with a water tank outlet;

[0007] The water tank water circuit board is an integral structure with the water tank. The water tank water circuit board is formed with a part of ice water circuit, a part of hot water circuit and a part of circulating sterilization water circuit. The part of ice water circuit is connected to the water outlet of the water tank. The part of hot water circuit on the water tank water circuit board includes a hot water faucet circuit.

[0019] Beneficial effects: The second end of the ice tank inlet water passage is located at the lower end of the water tank circuit board and is suitable for direct alignment with the inlet of the refrigeration component. The first end of the ice tank outlet water passage is located at the lower end of the water tank circuit board and is suitable for direct alignment with the outlet of the refrigeration component. Therefore, it is convenient to connect the ice tank inlet water passage with the inlet of the refrigeration component and the ice tank outlet water passage with the outlet of the refrigeration component. No connecting pipe is required, which facilitates assembly and can improve the assembly efficiency of the drinking water equipment.

[0027] Beneficial effects: Since air is present in the water after passing through the cooling components, it is necessary to vent it to maintain the pressure balance within the pipeline. By incorporating a vent in the water tank and a vent pipe in the water tank's manifold, one end of the vent pipe connects to the first pipe section, and the other end connects to the vent, allowing for the timely removal of air from the water flowing out of the cooling components. Furthermore, the vent pipe in the water tank's manifold enhances its integration, reducing the use of silicone tubing.

[0078] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0079] 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 to the heating element through the drain pipe. After being heated and boiled in the heating element, the water flows out from the outlet of the heating element, passes through the solenoid valve, and then flows through the tap for drinking. 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 drinking. When a user needs boiled water, the water pump pumps the water in the tank to the heating element, boils the water, and then the boiled water flows through the heat exchanger. Heat exchange occurs in the heat exchanger, and the water temperature is lowered to the user's desired temperature before flowing through the tap for drinking.

[0080] 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.

[0097] In this embodiment, the water outlet interface includes a cold water inlet interface 1151 and a hot water inlet interface 1152. The cold water inlet interface 1151 is connected to the ice tank water outlet channel 112, and the hot water inlet interface 1152 is connected to the hot water channel 113. This can prevent the water in the ice tank water outlet channel 112 and the water in the hot water channel 113 from mixing.

[0098] In one embodiment, the water tank water circuit board module further includes an ice water solenoid valve 80, which is located on the ice tank outlet water circuit 112 and downstream of the connection between the partial circulating sterilization water circuit 114 and the ice tank outlet water circuit 112.

[0099] In this embodiment, the water tank water circuit board module also includes an ice water solenoid valve 80. The ice water solenoid valve 80, the water tank 10, and the water circuit board are assembled into a module, which greatly simplifies the assembly steps of the water circuit system, improves the production efficiency of the drinking water equipment, and also facilitates the later maintenance and upgrading of the drinking water equipment.

[0100] In one specific embodiment, the water tank 10 is located above, the cooling component 30 is located below, and the height of the water outlet 50 is lower than the water level in the water tank 10. When the ice water solenoid valve 80 is opened, under the action of the water level difference in the water tank 10, the cold water in the cooling component 30 flows out to the water outlet 50 after passing through the ice water solenoid valve 80 for the user to drink.

[0101] In this embodiment of the water circuit board assembly, when the user needs to connect cold water, the chilled water solenoid valve 80 opens, such as... Figure 11 As shown, water in water tank 10 enters the ice chamber through the ice chamber inlet water passage 111 in the water tank water circuit board 110. After being cooled by the ice chamber, water flows through the ice chamber outlet water passage 112 to the outlet port, and finally flows out through the outlet 50 for drinking. When the user needs hot water, such as... Figure 12 As shown, the hot water heated by the heating element 20 flows through the heating element outlet water passage 211 to the hot water tap 113 in the water tank water passage plate 110, and finally flows out through the outlet 50 for the user to drink.

[0102] Specifically, when high-temperature cyclic sterilization is required, such as Figure 13 As shown, the hot water heated by the heating element 20 flows through the heating element outlet water passage 211 to the partial circulating sterilization water passage 114 in the water tank water passage plate 110, then flows to the ice tank outlet water passage 112, then enters the refrigeration component 30, and then flows into the water tank 10 from the ice tank inlet water passage 111 of the electronic ice tank. This realizes the circulation of water flowing out of the water tank 10 and back to the water tank 10. After multiple cycles, the effect of high-temperature circulating sterilization is achieved.

[0103] In one specific embodiment, the ice water solenoid valve 80 is fixed to the water tank circuit board 110 by a pressure plate 90 and screws.

[0104] In one specific embodiment, the ice water solenoid valve 80 and the ice tank outlet water passage 112 are sealed by two O-rings 91.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] In one specific embodiment, the vent 1006 is located on the water tank cover 1002.

[0110] In one embodiment, the side wall of the first pipe section 1121 has an opening 11211, through which part of the circulating sterilization water path 114 is connected to the first pipe section 1121. The opening 11211 is lower than the inlet port 118 of the ice water solenoid valve. Specifically, when the user needs to get cold water, the ice water solenoid valve 80 is opened, and the water in the water tank 10 enters the interior of the cooling element 30 through the ice tank inlet water path 111 in the water tank water circuit board 110. After being cooled by the cooling element 30, the water flows through the ice tank outlet water path 112 to the cold water inlet port 1151 of the water outlet, and finally flows out through the water outlet 50 for the user to drink. When the user needs to get hot water, the hot water heated by the heating element 20 flows through the heating element outlet water path 211 to the hot water path 113 of the water outlet in the water tank water circuit board 110, then flows to the hot water inlet port 1152 of the water outlet, and finally flows out through the water outlet 50 for the user to drink.

[0111] 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.

[0112] 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.

[0113] In this embodiment, since a cooling component 30 is provided below the water tank 10, the drain outlet 116 is connected to an L-shaped adapter 117, which can adjust the position of the drain pipe 103 and avoid interference with the cooling component 30.

[0114] 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 and two outlets) and 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 partial 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 after flowing out of the refrigeration component 30, it flows into the water tank 10 through the ice tank inlet water circuit 111, realizing the circulation of water flowing out of the water tank 10 and back to the water tank 10. After multiple cycles, the effect of high-temperature circulating sterilization is achieved.

[0115] 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.

[0117] In one embodiment, the water tank cover assembly includes a water tank cover 1002, a float valve assembly 1003, and a level switch 1004.

[0118] In this embodiment, the float valve assembly 1003 and the level switch 1004 are designed to facilitate the detection of the liquid level in the water tank 10. By assembling the float valve assembly 1003 and the level switch 1004 onto the water tank cover 1002, the water tank cover 1002, the float valve assembly 1003 and the level switch 1004 can be pre-assembled into a whole and then connected to the water tank body 1001, which can improve assembly efficiency.

[0119] In one embodiment, the water tank 10 is provided with an ultraviolet lamp assembly 1005.

[0120] In this embodiment, by installing an ultraviolet lamp assembly 1005 in the water tank 10, the water in the water tank 10 can be sterilized to prevent bacteria from growing in the water inside the water tank 10.

[0121] Specifically in one embodiment, such as Figure 8 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.

[0122] In one embodiment, the upper water circuit board 210 is integrally formed with a partial water inlet channel 212, the inlet of the partial water inlet channel 212 is adapted to connect to the water inlet pipe 101, and the outlet of the partial water inlet channel 212 is adapted to communicate with the water tank 10.

[0123] In this embodiment, the upper water circuit board 210 is integrally formed with a portion of the water inlet channel 212, which has a high degree of integration and can further reduce the number of parts, making assembly easier. Compared with the prior art, it reduces the use of silicone tubes, which not only avoids the aging and odor problems of silicone tubes, but also improves the sealing and stability of the entire system.

[0124] In one embodiment, the water inlet board module further includes a water inlet solenoid valve 60, which is located in part of the water inlet channel 212.

[0125] In this embodiment, the inlet solenoid valve 60, the three-way solenoid valve 40, and the water supply circuit 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.

[0126] In one specific embodiment, the water inlet solenoid valve 60 is fixed to the water inlet plate 210 by a pressure plate 90 and screws.

[0127] In one specific embodiment, the outlet of part of the water inlet channel 212 is connected to the water tank 10 via the water supply pipe 102.

[0128] According to an embodiment of the present invention, another aspect provides a drinking water device, including an ice-making module, a water circuit board assembly provided in the above embodiment, and a heating element 20.

[0129] The ice-making module includes a refrigeration component 30; a water tank water circuit board module is located above the refrigeration component 30, and an upper water circuit board module is located on one side of the refrigeration component 30. Part of the ice water circuit includes an ice tank inlet water circuit 111 and an ice tank outlet water circuit 112. Part of the circulating sterilization water circuit 114 is connected to the ice tank outlet water circuit 112. The first end of the ice tank inlet water circuit 111 is connected to the water tank outlet, the second end of the ice tank inlet water circuit 111 is connected to the inlet of the refrigeration component 30, and the first end of the ice tank outlet water circuit 112 is connected to the outlet of the refrigeration component 30.

[0130] In this embodiment, the water tank water circuit board module is located above the cooling component 30, and the upper water circuit board 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. This avoids the traditional silicone tubing connection method, solving the technical problems of traditional silicone tubing aging, developing odors, and affecting drinking water quality after prolonged use.

[0131] Furthermore, by directly connecting all water circuit functional units through the internal water circuits of the water circuit board module, the system sealing and stability of the drinking water equipment can be improved, the possibility of water leakage can be reduced, the system stability of the drinking water equipment can be enhanced, and the product lifespan of the drinking water equipment can be extended.

[0132] 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.
