When the ice delivery screw 63 starts to rotate, the ice cubes 62a stored in the ice storage container 61 will move to the first crushed ice compartment 68 under the action of the ice delivery screw 63, and flow into the first crushed ice compartment under the action of the guide 67. The interior of ice room 68. After the inflowing ice cubes 62a fall, they are led out to the distributor 27 through the groove 26 . When it is necessary to draw out the small ice cubes 62b, as shown in Figure 8, the controller is used to control the first solenoid valve 75 so that the first blocking plate 71 is in the crushing ice position, and at the same time control the second solenoid valve 95 so that the first 2 The blocking plate 91 is in the open position. When the ice delivery screw 63 starts to rotate, the ice cubes 62a in the ice storage container 61 will flow into the first ice crushing chamber 68, and the inflowing ice cubes 62a will be guided to the first fixed cutter 69 by the first blocking plate 71 superior. At this time, the first rotary cutter 70 can disintegrate the ice cubes 62a on the first fixed cutter 69 and the first blocking plate 71 into ice cubes 62b of a certain size during the rotation process, and the ice cubes after processing 62b will fall in the groove 26 through the 2nd crushed ice chamber 88, and finally draw on the distributor 27. And when it is necessary to draw tiny ice cubes 62c of the same size as ice chips, as shown in Figure 9, the controller can be used to make the first blocking plate 71 and the second blocking plate 91 respectively in the crushed ice position, and simultaneously drive The screw drives the motor 64 so that the ice delivery screw 63 starts to rotate. The ice cubes 62a sent out are first broken into small ice cubes 62b in the first ice crushing device 65, and then fall into the second crushed ice chamber 88, and the fallen small ice cubes 62b are guided to the second fixed ice by the second blocking plate 91. Cutter 89 on. At this moment, utilize controller to control cutter drive motor 92, so that the 2nd rotary cutter 90 rotates, and the small ice cube 62b on the 2nd fixed cutter 89 and the 2nd blocking plate 91 will be cut in the 2nd rotation. Under the rotation of the device 90, it is broken into tiny ice cubes 62c, which are finally drawn out of the refrigerator through the groove 26.
