In the related art, the cold tank and the hot tank of the water supply equipment are connected through the water system, and the air in the water system is not circulated, which is a good growth environment for bacteria. For a long time, it is easy to cause the bacteria in the water supply equipment to exceed the standard, which will cause health problems to the human body.

The water supply assembly provided according to the embodiment of the first aspect of the present application, please refer to FIG. 1 to FIG. 6 , includes a transfer water circuit board 100 and a circulating water circuit 110 .

The water supply equipment includes but is not limited to vertical drinking fountains, wall-mounted drinking fountains, and pipeline drinking fountains.

It should be noted that the water supply assembly is directly connected to the faucet 220 and the water supply port 212 of the waterway assembly 210, and the connection between the waterway assembly 210 and the waterway assembly 220 does not need to be connected by a hose, which can avoid missing connections, wrong connections, discounts, and high-temperature odors. In addition, the transfer waterway plate 100 does not need manual binding or fastening, and the airtightness is better during use.

At the same time, the transfer water circuit board 100 can be installed on the front shell of the water supply equipment. When assembling the front shell and the side shell of the water supply equipment, the water supply assembly can be quickly connected with the water circuit assembly 210 and the side shell, and the assembly efficiency is high. And a high degree of automation.

A plurality of water-guiding waterways 102 are formed inside the transfer waterway plate 100 , and each water-guiding waterway 102 is formed with a water inlet 104 and a water outlet 106 . The waterway assembly 210 is formed with a plurality of water supply ports 212, and different water supply ports 212 can provide drinking water of different temperatures. The water inlets 104 of the plurality of water guiding channels 102 are adapted to be connected to the water supply ports 212 of the water channel assembly 210 in one-to-one correspondence. The water outlet 106 of the transfer water circuit board 100 is suitable to be connected to the faucet 220, and drinking water of different temperatures can be delivered to the faucet 220, and the user can take water from the faucet 220 as required.

Referring to FIG. 1 to FIG. 6 , the water supply assembly provided by the embodiment of the present application further includes a circulating water channel 110 , and the circulating water channel 110 is connected to at least two of the plurality of water guiding channels 102 .

It is understandable that the interior of the waterway system is interconnected, and some waterways may be provided with structures such as valves. Adjusting the working status of the valves can keep the interior of the waterway system unimpeded.

The circulating waterway 110 can make the liquid in one or more water guiding waterways 102 flow to other water guiding waterways 102, and can form a self-circulating waterway system. The circulating waterway 110 can circulate the liquid inside the waterway system, and can fully flush the waterway system, thereby avoiding the breeding of bacteria in the waterway system and helping to improve the cleanliness of drinking water.

It should be noted that the on-off of the circulating water channel 110 can be controlled, and can be switched between a conduction state and a blockage state.

In the blocked state, the liquids among the plurality of water guiding channels 102 cannot communicate with each other, and the water guiding channels 102 realize the basic function of water supply.

In the conduction state, a self-circulating waterway system can be formed. The water guiding waterway 102 does not supply water to the faucet 220, and only flushes inside the waterway system. After flushing, the circulating liquid can be discharged through one or more water outlets 106. Of course, when the flushing frequency is high, there will be no bacteria in the water system, and the circulating water can continue to be used.

In some embodiments, the circulating waterway 110 and the transfer waterway plate 100 are integrally formed. The first aspect can reduce the production cost of the water supply assembly, the second aspect can improve the assembly efficiency of the water supply assembly, and the third aspect reduces the connection between pipelines. The structure can avoid water leakage of the water supply components.

In some other embodiments, the circulating water channel 110 is an independent pipeline, the circulating water channel 110 is arranged on one side of the transfer water channel plate 100 , and the circulating water channel 110 is connected to different water guiding channels 102 . Of course, the circulating waterway 110 may include multiple branches so as to be connected to multiple water guiding waterways 102 .

It can be understood that the circulating water channel 110 is a soft silicone tube or a plastic tube or the like.

In some embodiments, the multiple water guide channels 102 at least include a hot water channel 1022, a cold water channel 1024, and a warm water channel 1026. The hot water channel 1022 is used to provide hot water to users, and the water temperature is between 70 degrees Celsius and 90 degrees Celsius. The cold water channel 1024 is used to provide users with cold water, and the water temperature is between 2 degrees Celsius and 10 degrees Celsius. The warm water channel 1026 is used to provide users with warm water, and the water temperature is between cold water and hot water.

The circulating waterway 110 is connected to the hot waterway 1022 and the cold waterway 1024, so that the liquid in the hot waterway 1022 can flow into the cold waterway 1024, and the hot water can be used to flush and sterilize the waterway system.

It can be understood that when the circulating waterway 110 flushes the waterway system, the flow direction of the hot water is determined, and the high-temperature hot water can eliminate bacteria in the waterway system and inhibit the survival and reproduction of other microorganisms. The circulating water channel 110 extracts the hot water in the hot water channel 1022, and the hot water flows along the circulating water channel 110 to the cold water channel 1024, and then flows back to the cold tank 0130, and the liquid in the cold tank 0130 flows to the warm water channel 1026 and the hot tank 0140 again , The waterway system uses hot water to form a self-circulation sterilization, which fully improves the cleanliness and sanitation of the waterway system.

It should be noted that the hot water circulated in the waterway system can be reused or discharged at the water outlet 106 .

When the circulating water pump 120 is started, the circulating water channel 110 is turned on, and the liquid flow direction in the circulating water channel 110 is determined, for example, hot water is pumped to the cold water channel 1024 . When the circulating water pump 120 is turned off, the circulating water channel 110 is blocked, and there is no liquid flow between different water guiding channels 102 , which can avoid the phenomenon of temperature crossover.
