That is, the first water supply assembly and the second water supply assembly are disposed at both sides of the water pump 222 in a crossing manner.

Preferably, as shown in fig. 3 and 4, the first end 2211 of the water supply pipe 221 of the water pump is respectively communicated with the first water inlet pipe 234 and the second water outlet pipe 245 through a first pipe connector 250. Specifically, the first inlet conduit 234 and the second outlet conduit 245 are both connected to the first end 2211 of the water supply pipe 221 of the water pump, and a first pipe connector 250 is required to connect the three conduits. The first pipe connector 250 includes a first water inlet 251, a first water outlet 252 and a second water outlet 253, wherein the first water inlet 251 is communicated with the first water inlet pipe 234, the first water outlet 252 is communicated with the first end 2211 of the water supply pipe 221 of the water pump, and the second water outlet 253 is communicated with the second water outlet pipe 245. Specifically, the first conduit connector 250 is disposed at the first end 2211 of the water pump supply pipe 221, so that when the water pump 222 drives water to circulate in the first water supply assembly, water can flow into the water pump supply pipe 221 through the first water inlet pipe 234; and when the water pump 222 drives the water to circulate in the second water supply assembly, the water can flow from the water pump supply pipe 221 into the second water outlet pipe 245. The first pipeline connector 250 can be a tee pipe fitting, the tee pipe fitting is simple in structure, and three water pipes can be communicated with each other.

Preferably, as shown in fig. 3 and 5, the second end 2212 of the water supply pipe 221 of the water pump is respectively communicated with the second water inlet pipe 244 and the first water outlet pipe 235 through a second pipe connector 260. The second pipe connector 260 includes a second water inlet 261, a third water outlet 262 and a fourth water outlet 263, the second water inlet 261 is communicated with the second water inlet pipe 244, the third water outlet 262 is communicated with the second end 2212 of the water supply pipe 221 of the water pump, and the fourth water outlet 263 is communicated with the first water outlet pipe 235. Specifically, the second pipe connector 260 is disposed at the second end 2212 of the water pump supply pipe 221, so that when the water pump 222 drives water to circulate in the first water supply assembly, water can flow from the water pump supply pipe 221 into the first water outlet pipe 235; and water may flow from the second water inlet pipe 244 into the water pump supply pipe 221 when the water pump 222 drives water to circulate within the second water supply assembly. Similarly, the second pipe connector 260 may be a tee, which has a simple structure and can connect three water pipes.

Further, a third check valve 236 is disposed on the flow path of the first water outlet pipe 235, and the third check valve 236 is configured to allow water in the water pump supply pipe 221 to flow from the second end 2212 to the first water outlet pipe 235 in a single direction. A fourth check valve 246 is further disposed on the flow path of the second water outlet pipe 245, and the fourth check valve 246 is configured to allow water in the water supply pipe 221 of the water pump to flow from the first end 2211 to the second water outlet pipe 245 in a single direction. The third check valve 236 prevents water from the first outlet end 232 from flowing back to the pump supply pipe 221, and the fourth check valve 246 prevents water from the second outlet end 242 from flowing back to the pump supply pipe 221, thereby further ensuring that the two supply pipe assemblies can supply water separately without interfering with each other.

Specifically, when the water pump 222 rotates in a clockwise direction, water is driven to circulate in the first water supply assembly, and when the water pump 222 rotates in a counterclockwise direction, water is driven to circulate in the second water supply assembly. Alternatively, water may be driven to circulate within the first water supply assembly when the water pump 222 is rotated in a counterclockwise direction, and may be driven to circulate within the second water supply assembly when the water pump 222 is rotated in a clockwise direction.

In the embodiment of the present invention, when the water pump 222 rotates clockwise, since the first check valve 233 allows the water in the water tank 210 to flow from the first water inlet end 231 to the water pump water supply pipe 221 in one direction, and the third check valve 236 allows the water in the water pump water supply pipe 221 to flow from the second end 2212 to the first water outlet pipe 235 in one direction, the water pump 222 drives the water in the water tank 210 to flow from the first water inlet end 231 of the first water inlet pipe 234 to the water pump water supply pipe 221, and continues to enter the first water outlet end 232 of the first water outlet pipe 235 through the water pump water supply pipe 221, and finally enters the ice maker 103. In addition, when the water flows at the second end 2212 of the water pump supplying pipe 221, some water may flow to the second water inlet pipe 244, but the water does not flow back to the water tank 210 through the second water inlet pipe 244 because the second check valve 243 is in the blocking state in the direction from the second water inlet pipe 244 to the water tank 210.

When the water pump 222 rotates clockwise, the second check valve 243 allows the water in the water tank 210 to flow from the second water inlet end 241 to the water pump water supply pipe 221 in one direction, and the fourth check valve 246 allows the water in the water pump water supply pipe 221 to flow from the first end 2211 to the second water outlet pipe 245 in one direction, so that the water pump 222 drives the water in the water tank 210 to flow from the second water inlet end 241 of the second water inlet pipe 244 to the water pump water supply pipe 221, and continuously enters the second water outlet end 242 of the second water outlet pipe 245 through the water pump water supply pipe 221, and finally enters the water taking device 104. In addition, when the water flows at the first end 2211 of the water pump supplying pipe 221, some water may flow to the first water inlet pipe 234, but the first check valve 233 is in a blocking state in the direction from the first water inlet pipe 234 to the water tank 210, so that the water does not flow back to the water tank 210 through the first water inlet pipe 234.

Therefore, the waterway system disclosed by the invention enables the water pump to be started in different directions under the coordination of the first one-way valve, the second one-way valve, the third one-way valve and the fourth one-way valve of the water supply pipe device, so as to realize the respective water supply for the ice maker and the water taking device. Because the first check valve, the second check valve, the third check valve and the fourth check valve are all check valves which do not need to be powered after being installed, the structure is simple, and the installation and the use are easy, the installation of the electromagnetic valve is omitted, and the potential safety hazard brought to the whole refrigerator waterway system due to the fact that the electromagnetic valve needs to use strong electricity is avoided. Utilize the tee bend pipe fitting, can realize communicateing respectively the first end and the second end of water pump delivery pipe and first water supply pipe subassembly, second water supply pipe subassembly.
