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 to the heating element through the drain pipe. After being heated and boiled, the water flows out from the heating element's outlet, passes through the solenoid valve, and then flows to the tap for drinking. When a user needs ice water, the cold water in the ice tank flows through the ice water outlet solenoid valve and then to the tap for drinking. 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 a heat exchanger, where heat exchange occurs, cooling the water to the user's desired temperature before it flows to the tap for drinking.

[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.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0084] The embodiments of the present application will be described below in conjunction with Figures 1 to 21 .

[0085] As shown in Figure 1 , according to the embodiments of the present application, on the one hand, the present application provides a waterway plate assembly for a drinking water equipment, the drinking water equipment is provided with a water tank 10, a heating body 20 and a refrigeration part 30, the heating body 20 is used for heating water for the drinking water equipment, and the refrigeration part 30 is used for making ice water for the drinking water equipment. The heating body 20 includes but is not limited to a resistance wire heating body, an electric heating film, an electric heating sheet, a tubular heating body, etc.; the refrigeration part 30 includes but is not limited to an electronic ice tank, a compressor refrigeration device, etc.

[0086] Specifically, the heating body 20 is arranged in the hot water preparation pipeline of the drinking water equipment, and the refrigeration part 30 is arranged in the ice water preparation pipeline of the drinking water equipment, so as to respectively prepare hot water or ice water for the drinking water equipment.

[0087] As shown in Figures 2 to 4 , the waterway plate assembly comprises a lower waterway plate 310, a water tank waterway plate 110 and an upper waterway plate 210.

[0088] The lower waterway plate 310 is used for mounting the refrigerating part 30 and the heating body 20, and the water tank 10 and the heating body 20 are communicated through the lower waterway plate 310; the water tank waterway plate 110 is integrated to the water tank 10 and communicated with the water tank 10, and the water tank waterway plate 110 is communicated with the refrigerating part 30 and mounted above the refrigerating part 30; the upper waterway plate 210 is mounted above the lower waterway plate 310, and the upper waterway plate 210 is communicated between the heating body 20 and the water tank waterway plate 110; when hot water is taken, the water in the water tank 10 enters the lower waterway plate 310, is heated by the heating body 20, enters the upper waterway plate 210, and is discharged through the water nozzle hot water channel 113 on the water tank waterway plate 110; when ice water is taken, the water in the water tank 10 enters the water tank waterway plate 110, is cooled by the refrigerating part 30, and is discharged through the water nozzle cold water channel 115 on the water tank waterway plate 110.

[0089] In the above embodiment, the lower waterway plate 310, the water tank waterway plate 110 and the upper waterway plate 210 are respectively designed in an integrated waterway plate module and a modular manner, which not only improves the system sealing and stability of the drinking water equipment, but also simplifies the assembly process of the drinking water equipment and improves the production efficiency of the drinking water equipment. Moreover, the modular design of the drinking water equipment makes the maintenance and upgrading of the drinking water equipment more convenient, and also solves the problems of odor, complex assembly and pipeline mess in the traditional drinking water equipment, which brings low safety.

[0090] Specifically, the lower waterway plate 310 is arranged at the lower position of the whole machine, as a structure for supporting, directly supports the refrigerating part 30 and the heating body 20, and indirectly supports the water tank 10 through the refrigerating part 30 and the water tank waterway plate 110 arranged on the refrigerating part 30; at the same time, the lower waterway plate 310 also provides a mounting position for the upper waterway plate 210 and provides a supporting action for the upper waterway plate 210, so that the upper waterway plate 210 is vertically and stably mounted on the lower waterway plate 310, thus there is no need to separately design a supporting frame, the number of parts is reduced, the installation space is saved, and the miniaturization development of the drinking water equipment is facilitated. The water tank waterway plate 110 is integrally arranged on the water tank 10, and the specific arrangement manner can be that the water tank waterway plate 110 is integrally formed on the water tank 10, or the water tank waterway plate 110 is fixedly arranged on the water tank 10 through a fixed connection manner such as welding and bonding, which further reduces the assembly difficulty of the drinking water equipment. The upper waterway plate 210 is communicated between the heating body 20 and the water tank waterway plate 110, thereby providing a channel for the hot water of the heating body 20 to the water nozzle hot water channel 113 on the water tank waterway plate 110.

[0091] Further, as shown in FIG. 1, Figure 5 , Figure 6As shown, the water tank 10 is provided with a water storage cavity and is provided with a UV lamp for irradiation sterilization. The water storage cavity is closed by the water tank cover 10a, which is provided with a liquid level switch 121 and a mechanical float ball assembly to realize liquid level monitoring in the water storage cavity. Among them, the water tank waterway plate 110 is integrated in the water tank body, and the water tank cover 10a is detachably mounted to the water tank body. If the liquid level switch 121 and the mechanical float ball assembly of the water tank 10 fail to detect, the user can directly remove the water tank cover 10a from the water tank 10 to overhaul and maintain the liquid level switch 121 and the mechanical float ball assembly, which facilitates the user to disassemble and overhaul the liquid level switch and the mechanical float ball assembly. On the other hand, by integrating the water tank waterway plate 110 in the water tank body, the connection waterway between the water tank 10 and the heating body 20, the refrigeration part 30 and other components is shorter, which is beneficial to the space compactness of the drinking water equipment and the water outlet speed of the drinking water equipment.

[0092] Further, the water tank 10 is provided with a water storage cavity, a water tank waterway plate 110, a water tank cover 10a, an ice water electromagnetic valve 80, and a UV lamp. By integrating the water tank 10 and the water tank waterway plate 110 into an integrated structure, the technical effect of having a water storage function and a waterway water function through one part is realized.

[0093] Further, as shown in Figure 7 , Figure 9 , Figure 10 The water nozzle hot water waterway 113 and the water nozzle cold water waterway 115 are arranged in the water tank waterway plate 110. The water nozzle hot water waterway 113 is located at the side of the water tank 10; the waterway forming of the waterway plate is realized by the mold core-pulling structure in the water tank waterway plate 110, and the non-water outlet of the waterway is blocked by the plug assembly, thereby forming the water nozzle hot water waterway 113. The water nozzle cold water waterway 115 is located at the other side of the water tank 10; the waterway forming of the waterway plate is realized by the mold core-pulling structure in the water tank waterway plate 110, and the non-water outlet of the waterway is blocked by the plug assembly, thereby forming the water nozzle cold water waterway 115.

[0095] In the above embodiments, the circulating sterilization waterway 114 in the water tank waterway plate 110 provides a channel for the hot water flowing to the refrigeration part 30, so as to facilitate the user to perform high-temperature circulating sterilization on each water passing structure in the drinking water equipment, including the refrigeration part 30, the water tank 10 and the heating body 20.

[0096] Specifically, the water tank waterway plate 110 is integrally arranged on the water tank 10, and the circulating sterilization waterway 114 is arranged on the side of the water tank 10 and is arranged in parallel with the faucet hot water waterway 113.
