Abstract
Description
Technical Field
[0001] This utility model relates to the field of drinking water equipment technology, specifically to a drain pipe board 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.

[0068] The following is combined Figures 1 to 21 The following describes embodiments of the present invention.
[0069] like Figure 1 As shown, according to an embodiment of this utility model, in one aspect, this utility model provides a drain panel for a drinking water device. The drinking water device includes a water tank 10, a heating element 20, and a cooling component 30. The heating element 20 is used to produce hot water for the drinking water device, and the cooling component 10 is used to produce ice water for the drinking water device. The heating element 20 includes, but is not limited to, resistance wire heating elements, electric heating films, electric heating sheets, tubular heating elements, etc.; the cooling component 30 includes, but is not limited to, electronic ice tanks, compressor refrigeration devices, etc.
[0070] Specifically, the heating element 20 is installed in the hot water preparation pipeline of the water drinking equipment, and the cooling element 30 is installed in the ice water preparation pipeline of the water drinking equipment, thereby producing hot water or ice water for the water drinking equipment respectively.
[0071] like Figures 1 to 5 As shown, the drain panel 310 includes: a panel body and a water pipe 317.
[0072] The plate body is used to install the cooling component 30 and the heating element 20; the water pipe 317 is located in the plate body and is used to connect the water tank 10 and the heating element 20; when hot water is used, the water in the water tank 10 enters the heating element 20 through the water pipe 317, is heated by the heating element 20 and then discharged through the hot water pipe 113; when ice water is used, the water in the water tank 10 enters the cooling component 30 for cooling and is discharged through the cold water pipe 115.
[0073] In the above embodiments, the drain panel 310 adopts an integrated drain panel design, with the water pipes 317 housed within it. This not only improves the system sealing and stability of the drinking water equipment but also simplifies the assembly process and increases production efficiency. It also solves the safety issues associated with traditional drinking water equipment using silicone tubing, such as odor, complex assembly, and messy piping. Furthermore, the drain panel 310 itself supports the cooling element 30 and the heating element 20, eliminating the need for a separate support frame.
[0074] Specifically, the drain plate 310 is located at the bottom of the whole machine. As a supporting structure, it directly supports the cooling component 30 and the heating element 20. Therefore, there is no need to design a separate support frame, which reduces the number of parts and saves installation space, which is conducive to the miniaturization of drinking water equipment.
[0075] Furthermore, this embodiment also includes a water tank water circuit board 110 and an upper water circuit board 210, which together with the lower water circuit board 310 form a water circuit board assembly. The water tank water circuit board 110 is integrated into and communicates with the water tank 10, and is also communicated with and installed above the cooling component 30. The upper water circuit board 210 is installed above the lower water circuit board 310 and is connected between the heating element 20 and the water tank water circuit board 110. When hot water is used, the water in the water tank 10 enters the lower water circuit board 310, is heated by the heating element 20, enters the upper water circuit board 210, and is discharged through the hot water channel 113 on the water tank water circuit board 110. When ice water is used, the water in the water tank 10 enters the water tank water circuit board 110, is cooled by the cooling component 30, and is discharged through the cold water channel 115 on the water tank water circuit board 110. Therefore, the drain plate 310 indirectly supports the water tank 10 through the cooling component 30 and the water tank water circuit plate 110 mounted on the cooling component 30. The water tank water circuit plate 110 is integrated into the water tank 10. Specifically, the water tank water circuit plate 110 can be integrally formed and mounted on the water tank 10, or it can be fixed to the water tank 10 by welding, bonding, or other fixed connection methods, further reducing the assembly difficulty of the drinking water equipment. The water tank water circuit plate 110 is connected to the heating element 20, thereby providing a channel for the heating element 20 to guide hot water to the water tank water circuit plate 110 and the hot water circuit 113 of the faucet on it.
[0076] Furthermore, such as Figure 10 , Figure 11As shown, the water tank 10 is equipped with a water storage chamber and an ultraviolet lamp for sterilization. The water storage chamber is sealed by a water tank cover 10a, which is equipped with a level switch 121 and a mechanical float assembly to monitor the water level in the storage chamber. The water tank circuit board 110 is integrated into the water tank body, while the water tank cover 10a is detachably installed on the water tank body. If the level switch 121 and mechanical float assembly of the water tank 10 malfunction, the user can directly remove the water tank cover 10a from the water tank 10 to inspect and maintain the level switch 121 and mechanical float assembly, facilitating user disassembly and maintenance. Furthermore, by integrating the water tank circuit board 110 into the water tank body, the water path connecting the water tank 10 to components such as the heating element 20 and the cooling element 30 is shortened, which benefits the compactness of the drinking water equipment and the water dispensing speed.
[0077] Furthermore, the water tank 10 is equipped with a water storage chamber, a water tank water circuit board 110, a water tank cover 10a, an ice water solenoid valve 80, and an ultraviolet lamp. By integrating the water tank 10 and the water tank water circuit board 110 into a single structure, the technical effect of having both water storage and water flow functions in one component is achieved.
[0078] Furthermore, such as Figure 12 , Figure 14 , Figure 15 As shown, the hot water channel 113 and the cold water channel 115 of the faucet are arranged in the water tank water circuit plate 110. The hot water channel 113 of the faucet is located on the side of the water tank 10; the water channel of the water passage is formed in the water tank water circuit plate 110 by a mold core pulling structure, and the non-outlet of the water passage is sealed by a plug assembly, thereby forming the hot water channel 113 of the faucet.
[0079] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, in some embodiments, the drain panel 310 is provided with a third connecting pipe interface 313, and the water tank 10 is connected to the third connecting pipe interface 313 through the third connecting pipe 103, thereby connecting to the drain panel 310 and the heating element 20 on the drain panel 310.
[0080] In the above embodiment, the water tank 10 is connected to the heating element 20 on the drain plate 310 by the third connecting pipe 103, so that the water in the water tank 10 can enter the heating element 20 for heating under the pumping action of the water pump 70 to form hot water.
[0081] Specifically, the third connecting pipe interface 313 in the drain circuit board 310 is the water inlet of the internal pipes in the drain circuit board 310. Water in the water tank 10 flows through the third connecting pipe 103 and the internal pipes of the drain circuit board 310 connected by the third connecting pipe interface 313 to the heating element 20 for heating. The third connecting pipe 103 is made of odorless PE pipe or Teflon rigid pipe (not silicone flexible pipe).
[0082] Furthermore, the upper end of the third connecting pipe 103 is connected to the drain outlet of the water tank 10 via an L-shaped plug connector, and the lower end of the third connecting 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.
[0083] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 As shown, in some embodiments, the drain panel 310 is also provided with a water pump inlet interface 314 and a water pump outlet interface 311. The third connecting pipe interface 313 and the water pump inlet interface 314 are connected through the pipe in the drain panel 310. A water pump 70 is provided between the water pump inlet interface 314 and the water pump outlet interface 311. The water pump 70 is used to guide hot water.
[0084] In the above embodiment, the water pump inlet 314 and water pump outlet 311 provided in the drain panel 310 are used to stably install the water pump 70. The third connecting pipe interface 313 and the water pump inlet 314 are connected through the pipe in the drain panel 310 so that the water entering the third connecting pipe interface 313 flows to the water pump 70 and further flows to the subsequent heating element 20 for heating.
[0085] Specifically, water entering the drain plate 310 from the water tank 10 flows into the water pump 70 through the water pump inlet 314 and out of the water pump 70 through the water pump outlet 311, and then flows to the subsequent heating element 20 for heating. Multiple second sealing rings 710 are provided between the water pump inlet 314 and the water pump 70 inlet pipe, and between the water pump outlet 311 and the water pump 70 outlet pipe, to achieve sealing of the pipe connections.
[0086] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 9 As shown, in some embodiments, the drain panel 310 is also provided with a heating element interface 315. The water pump outlet interface 311 and the heating element interface 315 are connected through a water pipe 317, and the heating element interface 315 is provided with a heating element 20.
[0087] In the above embodiment, the heating element interface 315 provided in the drain panel 310 is used to stably install the heating element 20. The water pump outlet interface 311 and the heating element interface 315 are connected through the water pipe 317 in the drain panel 310 so that the water flowing out of the water pump 70 can flow to the heating element 20 for heating.
[0088] Specifically, the heating element 20 is vertically oriented, with its inlet end installed at the heating element interface 315 and its outlet end facing upwards. Water entering the drain pipe 310 from the water tank 10 flows through the water pump 70 and, under the pumping action of the water pump 70, flows from the inlet end of the heating element 20 to the outlet end, generating heat during this process. A third sealing sleeve 201 is provided between the heating element interface 315 and the inlet end of the heating element 20 to achieve a seal between the pipes.
[0089] In this embodiment, the drain panel 310 includes two internal pipe sections. First, the pipe between the third connecting pipe interface 313 and the water pump inlet interface 314; second, the pipe between the water pump outlet interface 311 and the heating element interface 315, which is also known as the water passage pipe 317.
[0090] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments, the drain panel 310 is provided with a drain outlet for discharging residual water from the water system of the drinking water device.
[0091] In the above embodiment, a drain outlet is provided in the drain panel 310 to allow users to manually drain residual water from the water system, thereby avoiding water residue in the pipes of each water panel, ensuring the cleanliness of the water system and preventing bacterial growth.
[0092] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments, the drain outlet includes a cold water drain outlet 3121, which is connected to the refrigeration component 30 and is used to drain residual water in the water circuit ice water system of the drinking water device.
[0093] In the above embodiment, a cold water drain outlet 3121 is provided so that the user can manually drain the residual water in the water circuit ice water system of the drinking water equipment.
[0094] Specifically, the cold water drain outlet 3121 is located at the bottom of the refrigeration unit 30 and communicates with the outside, thereby discharging the hot water after high-temperature circulating sterilization to the outside. A second sealing sleeve 320 is provided between the cold water drain outlet 3121 and the drain nozzle position at the bottom of the refrigeration unit 30 to achieve a circumferential sealing connection between the drain nozzle and the cold water drain outlet 3121. The cold water drain outlet 3121 extends towards the bottom of the drain plate 310 to facilitate rapid drainage.
[0095] In one optional embodiment, the drain outlet includes a hot water drain outlet 3122, which is connected to the water pipe 317 and is used to drain residual water in the hot water system of the drinking water equipment.
[0096] In the above embodiment, a hot water drain outlet 3122 is provided so that the user can manually drain the residual water in the hot water system of the drinking water equipment.
[0097] Specifically, the hot water drain outlet 3122 is connected to the water pipe 317 in the drain panel 310 that connects the water tank 10 and the heating element 20. Both the cold water drain outlet 3121 and the hot water drain outlet 3122 extend towards the bottom of the drain panel 310 to facilitate rapid drainage.
[0098] like Figures 1 to 4 , Figure 13 As shown, in some embodiments, the water tank water circuit board 110 is provided with a circulating sterilization water circuit 114 that is connected to the cooling component 30. The hot water heated by the heating element 20 enters the upper water circuit board 210 and is guided by the circulating sterilization water circuit 114 in the water tank water circuit board 110 to the cooling component 30, so that the hot water is circulated and sterilized at high temperature between the cooling component 30, the water tank 10 and the heating element 20.
[0099] In the above embodiment, a circulating sterilization water path 114 is provided in the water tank water circuit board 110 to provide a channel for hot water to flow to the cooling component 30, so that users can perform high-temperature circulating sterilization on various water passage structures in the drinking water equipment, including the cooling component 30, the water tank 10 and the heating element 20.
[0100] Specifically, the water tank water circuit board 110 is integrated on the water tank 10, and the circulating sterilization water circuit 114 is located on the side of the water tank 10 and is arranged side by side with the hot water circuit 113 near the water tap.
[0101] like Figure 1 , Figure 4 , Figure 16As shown, in some embodiments, the water circuit board assembly further includes a three-way solenoid valve 40 having an inlet, a first outlet, and a second outlet. The three-way solenoid valve 40 is installed between the upper water circuit board 210 and the water tank water circuit board 110. The inlet is connected to the heating element 20 through the upper water circuit board 210, the first outlet is connected to the hot water circuit 113 of the water tap, and the second outlet is connected to the circulating sterilization water circuit 114. When the inlet and the first outlet of the three-way solenoid valve 40 are connected, the drinking water equipment produces hot water. When the inlet and the second outlet of the three-way solenoid valve 40 are connected, the drinking water equipment performs high-temperature circulating sterilization.
[0102] In the above embodiment, by setting a three-way solenoid valve 40 to optimize the pipeline design of the drinking water equipment, an independent high-temperature circulation loop is formed in the drinking water equipment to perform high-temperature circulation sterilization on each water passage structure, including the cooling component 30, the water tank 10 and the heating element 20, and heat exchange between the cold and hot water systems of the drinking water equipment is avoided. Thus, while achieving efficient sterilization of the drinking water equipment, the temperature stability of the cold water system and the hot water system of the drinking water equipment is maintained.
[0103] Specifically, the three-way solenoid valve 40 is installed on the upper water circuit plate 210 with the inlet on one side, and the inlet is connected to the outlet pipe of the heating element 20 installed on the upper water circuit plate 210; the three-way solenoid valve 40 is installed on the water tank water circuit plate 110 with the first outlet and the second outlet on one side, and the first outlet is connected to the hot water circuit 113 of the faucet on the water tank water circuit plate 110, and the second outlet is connected to the circulating sterilization water circuit 114 on the water tank water circuit plate 110; a first sealing sleeve 410 is provided between the outlet pipe of the heating element 20 and the inlet of the three-way solenoid valve 40, between the hot water circuit 113 of the faucet and the first outlet of the three-way solenoid valve 40, and between the circulating sterilization water circuit 114 and the second outlet of the three-way solenoid valve 40, so as to achieve the sealing of the pipe connection.
[0104] Furthermore, the three-way solenoid valve 40 is a one-inlet, two-outlet valve. When the valve core of the three-way solenoid valve 40 blocks the second outlet, the inlet and the first outlet of the three-way solenoid valve 40 are connected for hot water production in the drinking water equipment. When the valve core of the three-way solenoid valve 40 blocks the first outlet, the inlet and the second outlet of the three-way solenoid valve 40 are connected for high-temperature circulating sterilization in the drinking water equipment.
[0105] like Figure 1 , Figure 3 As shown, in some embodiments, the drinking water equipment also includes a water pump 70, and a drain plate 310 is used to install the water pump 70. The water pump 70 is used to produce hot water for the drinking water equipment and to guide the water flow for high-temperature circulation sterilization.
[0106] In the above embodiment, the water pump 70 guides the hot water preparation and high-temperature circulation sterilization in the drinking water equipment, so that the hot water flows smoothly to the hot water outlet at the end of the hot water circuit 113 for the user to use, or performs high-temperature circulation sterilization between the cooling component 30, the water tank 10, the water pump 70 and the heating element 20.
[0107] Specifically, the water pump 70 is located in the water pipe 317 where the heating element 20 is located, and can be located upstream or downstream of the heating element 20. This ensures that when the water pump 70 is working, it guides hot water to the hot water outlet at the end of the hot water pipe 113, or allows the hot water to circulate and sterilize at high temperature between the cooling element 30, the water tank 10, the water pump 70, and the heating element 20.
[0108] like Figure 1 , Figure 3 , Figure 17 As shown, in some embodiments, the upper water circuit plate 210 is provided with a heating element water outlet channel 211, and the upper water circuit plate 210 is connected to the heating element 20 through the heating element water outlet channel 211.
[0109] In the above embodiment, the water outlet channel 211 of the heating element is provided in the water supply plate 210 to provide a channel for the hot water flowing out after the heating element 20 is heated, so that the hot water flowing out after the heating element 20 is heated can smoothly pass through the water supply plate 210 and enter the inlet of the three-way solenoid valve 40.
[0110] Specifically, the heating element water outlet channel 211 is formed inside the upper water channel plate 210 and located at the upper part of the upper water channel plate 210. The inlet of the heating element water outlet channel 211 is connected to the outlet of the heating element 20, and the outlet of the heating element water outlet channel 211 is connected to the inlet of the three-way solenoid valve 40. The water channel is formed in the upper water channel plate 210 through a mold core pulling structure. The non-outlet of the water channel is sealed by a plug assembly, thereby forming the heating element water outlet channel 211.
[0111] like Figure 1 , Figure 3 , Figure 17 , Figure 18 As shown, in some embodiments, the upper water circuit board 210 is provided with an inlet valve port 212 and an outlet valve port 213. The water circuit board assembly also includes an inlet solenoid valve 60 installed on the upper water circuit board 210, and the inlet solenoid valve 60 is connected between the inlet valve port 212 and the outlet valve port 213.
[0112] In the above embodiment, the water supply board 210 is provided with an inlet valve port 212 and an outlet valve port 213 for installing an inlet solenoid valve 60, so as to control the water inlet of the water tank 10.
[0113] Specifically, the inlet valve 212 and the outlet valve 213 are formed in the middle of the upper water circuit plate 210. The inlet solenoid valve 60 of the upper water circuit plate 210 has a threaded groove at its installation position. The inlet solenoid valve 60 is connected to the upper water circuit plate 210 by a first screw 610, thereby achieving stable installation with the upper water circuit plate 210. A first sealing ring 620 is provided between the pipeline between the inlet valve 212 and the outlet valve 213 and the inlet solenoid valve 60 to achieve a seal between the pipelines.
[0114] like Figure 1 , Figure 4 , Figure 17 As shown, in some embodiments, the water circuit board assembly further includes a first connecting pipe 101 and a second connecting pipe 102; one end of the first connecting pipe 101 is connected to an external water source, and the other end is connected to an inlet valve 212; one end of the second connecting pipe 102 is connected to an outlet valve 213, and the other end is connected to a water tank 10.
[0115] In the above embodiment, by setting the first connecting pipe 101 and the second connecting pipe 102, the external water source is introduced into the water tank 10 through the water inlet solenoid valve 60, thereby realizing the water filling operation of the water tank 10.
[0116] Specifically, the first connecting pipe 101 and the second connecting pipe 102 are made of odorless PE pipe or Teflon rigid pipe (not silicone flexible pipe).
[0117] like Figure 1 , Figure 4 , Figure 10 , Figure 11 As shown, in some embodiments, the water tank water circuit board 110 is provided with an ice tank inlet water circuit 111 and an ice tank outlet water circuit 112. The ice tank inlet water circuit 111 is connected to the water tank 10, and the ice tank outlet water circuit 112 is connected to the cold water outlet at the end of the water tap cold water circuit 115. The refrigeration component 30 is connected between the ice tank inlet water circuit 111 and the ice tank outlet water circuit 112.
[0118] In the above embodiment, the water tank water circuit board 110 is provided with an ice tank inlet water circuit 111 and an ice tank outlet water circuit 112 for stable installation of the refrigeration component 30; at the same time, the ice tank inlet water circuit 111 and the ice tank outlet water circuit 112 also provide support for the water tank water circuit board 110 and the water tank 10 on it, so that the water tank 10 is stably installed on the upper part of the refrigeration component 30 through the water tank water circuit board 110.
[0119] Specifically, the ice tank inlet water passage 111 and the ice tank outlet water passage 112 are located at the bottom of the water tank water passage plate 110. The ice tank inlet water passage 111 and the ice tank outlet water passage 112 are arranged close to each other so as to connect with the inlet and outlet of the refrigeration component 30.
[0120] like Figure 1 , Figure 4 , Figure 10 , Figure 19 As shown, in some embodiments, the water circuit board assembly also includes an ice water solenoid valve 80 installed on the water tank water circuit board 110, the ice water solenoid valve 80 being connected between the ice tank outlet water circuit 112 and the water tap cold water circuit 115.
[0121] In the above embodiment, the water tank water circuit board 110 provides an installation position for the ice water solenoid valve 80. The ice water solenoid valve 80 is connected between the ice tank outlet water circuit 112 and the water tap cold water circuit 115 so that the user can take the ice water cooled by the refrigeration component 30 at the appropriate time.
[0122] Specifically, the chilled water solenoid valve 80 is fixed to the water tank circuit board 110 by two upper and lower pressure plates 810 and two upper and lower second screws 820; a third sealing ring 830 is provided at the connection position between the chilled water solenoid valve 80 and the water tank circuit board 110 to improve the sealing performance. A cold water channel 115 connected to the water tap cold water channel 115 is provided on the water tank circuit board 110, and the chilled water solenoid valve 80 is connected between the ice tank outlet water channel 112 and the water tap cold water channel 115.
[0123] like Figure 2 , Figure 3 , Figure 20 As shown, in a second aspect, this utility model provides a drinking water device, including: a device body and a water circuit board assembly.
[0124] The main body of the equipment includes a water tank 10, a heating element 20, and a cooling element 30. A water circuit board assembly is installed on the main body of the equipment. The water circuit board assembly includes a lower water circuit board 310 as described in the above embodiment, a water tank water circuit board 110, and an upper water circuit board 210. The lower water circuit board 310 is equipped with the cooling element 30 and the heating element 20, and the water tank 10 and the heating element 20 are connected through the lower water circuit board 310. The water tank water circuit board 110 is integrated into the water tank 10 and connected to the water tank 10. The water tank water circuit board 110 is connected to the cooling element 30 and installed above the cooling element 30. The upper water circuit board 210 is installed above the lower water circuit board 310 and is connected between the heating element 20 and the water tank water circuit board 110.
[0125] In the above embodiments, the drain circuit board 310, the water tank circuit board 110, and the water inlet circuit board 210 adopt integrated circuit board modules and modular designs, respectively. This not only improves the system sealing and stability of the drinking water equipment but also simplifies the assembly process and increases production efficiency. Furthermore, the modular design of the drinking water equipment makes maintenance and upgrades more convenient, while also solving the problems of odor, complex assembly, and low safety caused by messy pipelines in traditional drinking water equipment using silicone tubing.
[0126] Specifically, the heating element 20, in conjunction with the water circuit board assembly, is used to produce hot water or perform high-temperature circulation sterilization for the drinking water equipment, while the cooling element 30, in conjunction with the water circuit board assembly, is used to produce ice water for the drinking water equipment, thereby realizing the multiple water intake functions of the drinking water equipment.
[0127] like Figure 2 , Figure 3 , Figure 4 , Figure 13 , Figure 14 As shown, in some embodiments, the water circuit board assembly is provided with a hot water channel 113 and a cold water channel 115; the main body of the equipment also includes a water outlet 50, which is connected to the hot water outlet at the end of the hot water channel 113 and the cold water outlet at the end of the cold water channel 115 respectively, and the height of the water outlet 50 is lower than the height of the bottom plate of the water tank 10.
[0128] In the above embodiment, the height of the water outlet 50 is lower than the height of the bottom plate of the water tank 10, so that the height of the water outlet 50 is lower than the lowest water level in the water tank 10. When the ice water solenoid valve 80 is opened, under the action of the liquid level difference, the ice water in the refrigeration unit 30 flows out naturally to the water outlet 50 under the action of gravity, which is used to provide drinking water to the user, thus realizing the water passage for the refrigeration unit 30 to produce water.
[0129] Specifically, the water outlet 50 has two inlets and one outlet. The two inlets are connected to the hot water outlet at the end of the hot water path 113 and the cold water outlet at the end of the cold water path 115, respectively. The outlet provides users with hot or cold water. By separating the hot and cold water channels of the water outlet 50 into the hot water path 113 and the cold water path 115, the phenomenon of cross-temperature mixing of hot and cold water at the water outlet 50 is reduced.
[0130] like Figure 20 , Figure 21 As shown, in some embodiments, the drinking water equipment also includes a water dispenser 100, which has a front shell assembly 200 and a rear shell assembly 300 arranged opposite to each other, forming a receiving cavity between the front shell assembly 200 and the rear shell assembly 300, and the equipment body and the water circuit board assembly are disposed in the receiving cavity.
[0131] Specifically, the rear housing assembly 300 includes a rear housing 301 and a power adapter 302 and a controller 303 disposed on the rear housing 301.
[0132] The water flow paths of the drinking water equipment provided in this embodiment under various working states are as follows:
[0133] When filling with water: First connecting pipe 101 → water inlet solenoid valve 60 on water supply circuit board 210 → second connecting pipe 102 → water tank 10.
[0134] When producing hot water: Water tank 10 → Third connecting pipe 103 → Water pump 70 on drain pipe 310 → Water pipe 317 in drain pipe 310 → Heating element 20 on drain pipe 310 → Water outlet 211 of heating element in water supply pipe 210 → Three-way solenoid valve 40 (first outlet) between water supply pipe 210 and water tank water supply pipe 110 → Hot water faucet 113 in water tank water supply pipe 110 → Water outlet 50 on water tank water supply pipe 110.
[0135] During ice water making: Water tank 10 → Ice chamber inlet water passage 111 in water tank water circuit board 110 → Refrigeration component 30 → Ice chamber outlet water passage 112 in water tank water circuit board 110 → Ice water solenoid valve 80 in water tank water circuit board 110 → Cold water passage 115 in water tap in water tank water circuit board 110 → Water outlet 50 on water tank water circuit board 110.
[0136] During high-temperature circulating sterilization: Water tank 10 → Third connecting pipe 103 → Water pump 70 on the drain circuit board 310 → Water pipe 317 in the drain circuit board 310 → Heating element 20 on the drain circuit board 310 → Heating element outlet water passage 211 in the upper water circuit board 210 → Three-way solenoid valve 40 (second outlet) between the upper water circuit board 210 and the water tank water circuit board 110 → Circulating sterilization water passage 114 in the water tank water circuit board 110 → Ice tank outlet water passage 112 in the water tank water circuit board 110 → Refrigeration component 30 → Ice tank inlet water passage 111 in the water tank water circuit board 110 → Water tank 10.
[0137] 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 the appended claims.
