- the stop portion 732 includes an end 732 a away from the ice ejection substrate 13 and a junction end 732 b that intersects the substrate surface 135 of the ice ejection substrate 13.
- the cross-sectional thickness of the stopper 732 gradually decreases along the direction from the junction end 732b to the end 732a, thereby effectively balancing the blocking force for blocking the broken ice and the elastic force required for rounding the ice.
- the height of the stopper 732 is lower than the vertical height of the lowermost movable ice blade 52.
- the fixing portion 731 is in close contact with the side wall portion 134 of the ice discharging substrate 13 to fix the stopper 73 on the end surface of the ice discharging substrate 13.
- the fixing part 731 may be integrally formed with the stop part 732.
- the stopper 73 and the housing 11 are two-shot injection molded.
- the movable ice blade 52 When the ice is rounded, the movable ice blade 52 will push the ice cubes to drive the stopper 73 to elastically deform. When the ice cubes reach the ice discharge port 131, the whole ice will fall; after the ice rounding is completed, the stopper 73 will be elastic. Under the action of restoring force, return to the initial position. When the ice box is taken out, the stopper 73 is not subject to external force and does not deform. Due to the stopper effect of the stopper 73, the broken ice can be effectively prevented from falling from the ice discharge opening 131.
- the rounded ice state is defined as the second state, and the states other than the rounded ice state are defined as the first state.
- the first state includes the state of taking out the ice box from the refrigerator or the state of vibration generated by the user when opening and closing the door of the refrigerator.
- the stopper 73 When the ice crushing device 100 is in the first state, the stopper 73 is in the initial state and forms a stop surface at the ice discharge port 131 for preventing the ice from falling; when the ice crushing device 100 is in the second state, the external force Under the action of (that is, the external force exerted on the stopper 73 by the movable ice blade 52 pushing the ice cube), the stopper 73 changes in shape to release the stop surface, and under the external force (ie, the movable ice blade 52 pushes the ice cube against the stopper 73). After the external force applied by 73) disappears, the stopper 73 returns to the initial state under the action of its own elasticity.
- the stopper 73 not only can effectively prevent the broken ice from falling, but also does not affect the ice-forming rate, and has the function of automatically returning to the initial state through its own elastic properties.
- the driving object of the driving mechanism 30 can also be replaced with the ice blade shaft 51, that is, the driving mechanism 30 drives the ice blade shaft 51 to rotate, and the ice bucket 12 is fixed relative to the housing 11. Since the drive mechanism 30 drives the ice blade shaft 51 to rotate and the ice bucket 12 is fixed relative to the housing 11, the ice crushing method is the prior art, and will not be repeated here.
