1. and (3) automatic storage: as shown in fig. 1, the liquid water in the water storage layer 222 at the lower end of the ice bin 22 is delivered from the first ice pipe 31 to the inlet B of the ice making unit 10 through the outlet a, and the ice water mixture in a fluid state generated by the ice making unit 10 flows out through the outlet C of the ice making unit 10 and flows into the inlet D of the ice storage layer 224 to enter the ice bin 22, and the mixed ice slurry is automatically layered after flowing into the ice bin 22 because the density of the ice is lower than that of the water. After the ice-water mixture enters the ice bin 22 for layering, the automatic sensing of the water level and the ice level is carried out through the first liquid level sensor 71 and the second liquid level sensor 72 in the ice bin 22, the water quantity in the ice bin 22 is fed back to the controller 70 through the second liquid level sensor 72, the controller 70 automatically outputs a control second switch valve 76 according to the feedback signal to open the water supplementing of the ice bin 22, the water quantity and the ice quantity in the ice bin 22 are increased along with continuous water supplementing and cooling of the ice making unit 10, when the first liquid level sensor 71 is triggered, the first liquid level sensor 71 automatically feeds back the signal to the controller 70, the controller 70 automatically controls the two switch valves 76 to close according to the feedback signal output to stop water supplementing, the water in the water storage layer 222 at the lower part of the ice bin 22 can still continue to circulate with the ice making unit 10 to continuously prepare ice-water mixture, the ice in the upper ice storage layer 224 in the ice bin 22 is accumulated more and more, more water in the ice bin 22 is converted into ice due to the fact that the density of the ice is smaller than that of the water, and the volume of the ice is larger than that of the water under the same mass, so when the upper ice storage layer 224 in the ice bin 22 triggers to a position sensor on the ice pulling unit 60, the position sensor sends a feedback signal to the controller 70, the controller 70 automatically outputs a signal to the ice making unit 10 and the first switch valve 753, finally the ice making cycle is stopped, and the storage state is completed. .
