Referring to fig. 1 to 6, the water supply assembly provided in the embodiment of the invention further includes a circulation waterway 110, and the circulation waterway 110 is connected to at least two of the plurality of water diversion waterways 102.

It can be understood that the waterway system is internally communicated with each other, and a part of the waterway system may be provided with a valve and other structures, so that the waterway system can be kept smooth by adjusting the working state of the valve.

The circulation waterway 110 may enable the liquid in one or more of the water diversion waterways 102 to flow to other water diversion waterways 102, and may form a self-circulation waterway system. The circulation waterway 110 can circulate the liquid in the waterway system, so as to comprehensively wash the waterway system, further avoid bacteria breeding in the waterway system, and help to promote the clean degree of the drinking water.

The on/off state of the circulation water path 110 may be controlled, and may be switched between a conductive state and a blocking state.

In the blocking state, the liquid between the plurality of water diversion waterways 102 cannot flow mutually, and the water diversion waterways 102 realize the basic water supply function.

In the on state, a self-circulating waterway system can be formed, the water diversion waterway 102 does not supply water to the tap 220, only the inside of the waterway system is flushed, and the circulating liquid can be discharged through one or more water outlets 106 after the flushing is finished. Of course, when the flushing frequency is higher, the waterway system has no bacteria breeding, and the circulating water can be continuously utilized.

In some embodiments, the circulation waterway 110 and the adapting waterway board 100 are integrally formed, so that the production cost of the water supply assembly can be reduced in the first aspect, the assembly efficiency of the water supply assembly can be improved in the second aspect, the connection structure between the pipelines is reduced in the third aspect, and the water leakage phenomenon of the water supply assembly can be avoided.

In other embodiments, the circulation waterway 110 is a separate pipeline, the circulation waterway 110 is disposed on one side of the adapting waterway board 100, and the circulation waterway 110 is connected to different water diversion waterways 102. Of course, the circulation waterway 110 may include a plurality of branch ports so as to be connected to a plurality of water diversion waterways 102.

When the circulating water pump 120 is inserted into the circulating water channel 110, the circulating water pump 120 is fixed in the limiting piece 122 through a screw or other easily detachable structure, so that on one hand, the stability of the circulating water pump 120 can be improved, and on the other hand, the circulating water pump 120 can be replaced quickly.

According to the water supply assembly provided by the embodiment of the invention, the circulating waterway 110 is communicated with at least two water guide waterways 102 of the adapting waterway plate 100, so that a waterway system for self-circulation flushing can be formed, bacterial growth in the waterway system can be inhibited, and the quality of drinking water is further improved.

In some embodiments, the water supply assembly further includes a sterilizing member 150, wherein a sterilizing line is formed inside the sterilizing member 150, the sterilizing line being in communication with the water outlet 106.

In some embodiments, the valves 140 are solenoid valves that electrically control the switching of the water conduit 102 between the conductive state and the blocking state.

Under the condition that the water guide waterway comprises a hot water waterway 1022, a cold water waterway 1024 and a warm water waterway 1026, a plurality of touch switches are arranged on the casing 200 of the water supply equipment and are connected to the valve 140 in a one-to-one correspondence manner, and the hot water waterway 1022, the cold water waterway 1024 and the warm water waterway 1026 are respectively controlled to discharge water.

When the temperature of the water in the hot tank 0140 increases, the volume of the hot water expands, and when the temperature of the water is heated to 90 degrees celsius or higher, the expansion coefficient of the hot water is 5% to 10%. Therefore, when the hot tank 0140 is filled with water, the heated and expanded hot water flows back along the third water channel 0122, which results in the rising of the water temperatures in the third water channel 0122, the fourth water channel 0124 and the cold tank 0130, namely, the temperature-crossing phenomenon, which seriously affects the use experience of the user and increases unnecessary energy consumption.

Assuming that the trap 0150 has a capacity of Q1, the hot tank 0140 has a capacity of Q2, the expansion coefficient after water heating is K, and the expansion coefficient K is between 5% and 10% when the water is heated to 90 degrees celsius or higher. When the temperature of the water in the hot tank 0140 increases, the following relationship needs to be satisfied in order to avoid backflow of the hot water:

Q1≥K*Q2

Q1≥2*K*Q2

that is, trap 0150 reserves 2 times the expansion capacity.
