TECHNICAL FIELD

[0002] Currently, the pipeline machine used in the household market mainly consists of a water tank, a controller module, a heating body, an ice tank component, a water pump, a solenoid valve, a waterway system and the like. When a user needs boiled water, the water in the water tank is pumped to the heating body through the downcomer pipe, heated in the heating body, and then flows out from the heating body outlet. After passing through the solenoid valve, the boiled water flows through the water outlet faucet for the user to drink. When the user needs cold water, the cold water in the ice tank flows through the cold water outlet solenoid valve and then flows through the water outlet faucet for the user to drink. When the user needs hot water, the water pump pumps the water in the water tank to the heating body to boil the water. After the boiled water flows through the heat exchanger, heat exchange is performed in the heat exchanger to reduce the water temperature to the temperature required by the user, and then the water flows through the water outlet faucet for the user to drink.

[0003] At present, the waterway system of the pipeline machine is connected by silica gel pipes, stainless steel pipes, PE pipes and the like through various connectors. When boiled water flows through the waterway system connected by silica gel pipes, the water will have the taste of silica gel pipes, which is a user pain point.

[0075] The embodiments of the present application will be described below in conjunction with Figure 1 .

[0076] As shown in Figure 2 to Figure 4 , according to the embodiments of the present application, on the one hand, the present application provides a waterway plate assembly for a water drinking device, the water drinking device 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 water drinking device, and the refrigeration part 30 is used for making ice water for the water drinking device. The heating body 20 includes but is not limited to resistance wire heating body, electric heating film, electric heating sheet, tubular heating body, etc.; the refrigeration part 30 includes but is not limited to electronic ice tank, compressor refrigeration device, etc.

[0077] Specifically, the heating body 20 is arranged in the hot water preparation pipeline of the water drinking device, and the refrigeration part 30 is arranged in the ice water preparation pipeline of the water drinking device, so as to respectively prepare hot water or ice water for the water drinking device.

[0078] As shown in Figure 5 , the waterway plate assembly comprises a lower waterway plate 310 and a water tank waterway plate 110.

[0079] 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 water tank waterway plate 110 is communicated with the heating body 20; 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, 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 refrigerated by the refrigerating part 30, and is discharged through the water nozzle cold water channel 115 on the water tank waterway plate 110.

[0080] In the above embodiment, the lower waterway plate 310 and the water tank waterway plate 110 respectively adopt the integrated waterway plate module and the modular design 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.

[0081] Specifically, the lower waterway plate 310 is arranged at the lower position of the whole machine, as a structure playing a supporting role, directly plays a supporting role for the refrigerating part 30 and the heating body 20, and indirectly plays a supporting role for the water tank 10 through the refrigerating part 30 and the water tank waterway plate 110 arranged on the refrigerating part 30, so that a separate support frame is not needed, 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, further reducing the assembly difficulty of the drinking water equipment. The water tank waterway plate 110 is communicated with the heating body 20, 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.

[0082] Further, the communication manner of the water tank waterway plate 110 and the heating body 20 can also adopt a waterway plate form. Specifically, the waterway plate assembly further includes an upper waterway plate 210 mounted on 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. In this way, the upper waterway plate 210 provides a channel for the hot water of the heating body 20 to the water tank waterway plate 110 and the water nozzle hot water channel 113 thereon, and the lower waterway plate 310 provides a mounting position for the upper waterway plate 210 and provides a supporting role for the upper waterway plate 210, so that the upper waterway plate 210 is vertically and stably mounted on the lower waterway plate 310.

[0083] Further, as shown in Figure 6 、 Figure 7 , the water tank 10 is provided with a water storage cavity and is provided with an ultraviolet lamp for irradiation sterilization. The water storage cavity is closed by the water tank cover 10a, and the water tank cover 10a 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 water circuit board 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 disassemble 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 is convenient for 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 water circuit board 110 in the water tank body, the connection water circuit 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.

[0084] Further, the water tank 10 is provided with a water storage cavity, a water tank water circuit board 110, a water tank cover 10a, an ice water electromagnetic valve 80, and an ultraviolet lamp. By integrating the water tank 10 and the water tank water circuit board 110 into an integrated structure, the technical effect of having a water storage function and a water circuit water function through one part is realized.

[0085] Further, as shown in Figure 9 、 Figure 10 、 Figure 1 to Figure 4 , the water nozzle hot water circuit 113 and the water nozzle cold water circuit 115 are arranged in the water tank water circuit board 110. The water nozzle hot water circuit 113 is located at the side of the water tank 10; the water circuit forming of the water circuit is realized by the mold core structure in the water tank water circuit board 110, and the non-water outlet of the water circuit is blocked by the plug assembly, thereby forming the water nozzle hot water circuit 113.

[0087] In the above embodiment, the circulating sterilization water circuit 114 in the water tank water circuit board 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.

[0088] Specifically, the hot water after the heating body 20 is heated enters the upper waterway plate 210, then enters the water tank waterway plate 110, and is guided by the circulating sterilization waterway 114 in the water tank waterway plate 110 to the refrigeration part 30, so that the hot water is high-temperature circulating sterilized among the refrigeration part 30, the water tank 10 and the heating body 20. The water tank waterway plate 110 is integrally arranged on the water tank 10, and the circulating sterilization waterway 114 is located at the side of the water tank 10 and arranged side by side with the water nozzle hot water way 113.

[0090] In the above embodiment, by arranging the three-way electromagnetic valve 40, the pipeline design of the drinking water equipment is optimized, an independent high-temperature circulating loop is formed in the drinking water equipment to perform high-temperature circulating sterilization on each water passing structure including the refrigeration part 30, the water tank 10 and the heating body 20, and heat exchange between the cold water system and the hot water system of the drinking water equipment is avoided, so that the high-efficiency sterilization of the drinking water equipment is realized, and the temperature stability of the cold water system and the hot water system of the drinking water equipment is maintained.

[0091] Specifically, the three-way electromagnetic valve 40 is installed between the upper waterway plate 210 and the water tank waterway plate 110, and the water inlet is communicated with the heating body 20 through the upper waterway plate 210. One side of the three-way electromagnetic valve 40 provided with the water inlet is installed on the upper waterway plate 210, and the water inlet is communicated with the water outlet pipeline of the heating body 20 arranged on the upper waterway plate 210; one side of the three-way electromagnetic valve 40 provided with the first water outlet and the second water outlet is installed on the water tank waterway plate 110, the first water outlet is communicated with the water nozzle hot water way 113 on the water tank waterway plate 110, and the second water outlet is communicated with the circulating sterilization waterway 114 on the water tank waterway plate 110; a first sealing sleeve 410 is arranged between the water outlet pipeline of the heating body 20 and the water inlet of the three-way electromagnetic valve 40, between the water nozzle hot water way 113 and the first water outlet of the three-way electromagnetic valve 40, and between the circulating sterilization waterway 114 and the second water outlet of the three-way electromagnetic valve 40, so as to realize the sealing of the pipeline connection.

[0092] Further, the three-way electromagnetic valve 40 is a two-in and one-out valve. When the spool of the three-way electromagnetic valve 40 blocks the second water outlet, the water inlet and the first water outlet of the three-way electromagnetic valve 40 are communicated, which is used for the water heating device to heat water. When the spool of the three-way electromagnetic valve 40 blocks the first water outlet, the water inlet and the second water outlet of the three-way electromagnetic valve 40 are communicated, which is used for the water heating device to perform high-temperature circulation sterilization.

[0093] As shown in Figure 3 , Figure 1 illustrated, in some embodiments, the water heating device further comprises a water pump 70, and the lower water circuit board 310 is used for mounting the water pump 70. The water pump 70 is used for guiding the water flow for the water heating device to heat water and perform high-temperature circulation sterilization.

[0094] In the above-mentioned embodiments, the water pump 70 is used for guiding the hot water for the water heating device to heat water and perform high-temperature circulation sterilization, so that the hot water flows to the hot water outlet at the end of the hot water waterway 113 of the water nozzle for the user to take, or the high-temperature circulation sterilization is performed among the refrigeration part 30, the water tank 10, the water pump 70 and the heating body 20.

[0115] 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.

When the ice water electromagnetic valve 80 is opened, under the action of the liquid level difference, the ice water in the refrigerating part 30 naturally flows out to the water outlet nozzle 50 for the user to drink under the action of gravity, realizing the water channel passage of the water outlet of the refrigerating part 30.
