Definitions

  • an ice crushing device comprises a housing assembly, the housing assembly comprising a housing and an ice bank supported within the housing; an ice crushing mechanism disposed in the ice bank and comprising an ice cutter shaft, several movable ice cutters and several stationary ice cutters disposed on the ice cutter shaft at an interval; a driving mechanism for driving the ice bank or ice cutter shaft to rotate, at least a portion of the driving mechanism being mounted in the housing; the housing assembly further comprises an ice-discharging substrate provided at the bottom of the ice bank, the ice-discharging substrate is provided with an ice-discharging port communicated with the ice bank, and ice cubes prepared by the ice maker are crushed by the ice crushing mechanism in the ice bank and then discharged through the ice-discharging port; a stop assembly disposed in the ice bank; when the ice crushing device is in a first state, the stop assembly is in an initial state and
  • the restoring member is a torsion spring which is disposed on the fixed portion and located at an end away from the housing.
  • a first preferred embodiment according to the present invention discloses a refrigerator.
  • the refrigerator comprises a cabinet and a door body for opening or closing the cabinet.
  • the cabinet defines storage compartments.
  • the number and structure of the storage compartments may be configured according to different needs.
  • the storage compartments usually comprise a refrigerating compartment and a freezing compartment.
  • the cylindrical gear 31 and the second bevel gear 33 are disposed coaxially and relatively fixedly, that is, the motor drives the first bevel gear 32 to rotate, and the cylindrical gear 31 and the second bevel gear 33 rotate synchronously, to thereby realize the transmission of a torque from the motor to the ice bank 12.
  • the overall size of the driving mechanism may be reasonably designed, so that the engagement between the motor and the gear assembly is more compact such that the overall volume of the ice crushing device becomes smaller.
  • the driving mechanism may also be other transmission structures, such as a belt transmission mechanism, a chain transmission mechanism, a worm wheel-worm mechanism etc.
  • the gear mechanism is not limited to bevel gears, but may also be spur gears, helical gears, herringbone gears, curved gears, and so on.
  • the housing assembly 10 further comprises a bottom plate 14, the bottom of the second portion 11b is open, and the bottom plate 14 covers the bottom of the second portion 11b to seal the cylindrical gear 31 between the second portion 11b and the bottom plate 14.
  • the bottom of the ice-discharging substrate 13 is provided with a clamping slot 133.
  • the bottom plate 14 is provided with a bump 143 that is shaped to fit in the clamping slot 133.
  • the bump 143 is fitted in the clamping slot 133.
  • both the bump 143 and the clamping slot 133 are both set in a fish shape to enable a better overall sealing perform of the ice crushing device.
  • the stopper 73 comprises a stopping portion 732 and a fixed portion 731.
  • the stopping portion 732 is a plate-like structure having a predetermined height in the vertical direction and a predetermined length in the horizontal direction, and forms a stopping surface with its own structure to thereby prevent the ice cubes from falling.
  • the fixed portion 731 is generally cylindrical and comprises a first through hole 731b and a stepped surface 731a.
  • the stepped surface 731a serves as a first fixed end face for fixing the elastic member 72.
  • the first through hole 731b is used to mate with the ice cutter shaft 51. In the present embodiment, the shaft core 515 of the ice cutter shaft 51 passes through the first through hole 731b.
  • the stop assembly When the ice crushing device 100 is in the first state, the stop assembly is in the initial state and a stopping surface is formed at the ice-discharging port 131 to stop the ice cubes from falling; when the ice crushing device 100 is in the second state, the stop assembly displaces under the action of an external force (namely, an external force applied by the movable ice cutters 52 pushing the ice cubes on the stopper 73) to release the stopping surface. After the external force disappears, the stop assembly returns to the initial state.
  • the stop assembly has a function of effectively preventing the fall of the crushed ice without affecting the entire ice supply rate, as well as automatically returning to the initial state.
  • the torsion spring is abutted against by the ice cutter shaft 51, and the other end of the torsion spring is abutted against by the connection of the fixed portion 731 and the stopping portion 732.
  • the fixed portion 731 is snap-fitted into the snap-fitting portion 132, and the spring is sleeved on the end of the fixed portion 731 adjacent to the ice cutter shaft 51.
  • the object driven by the driving mechanism 30 may also be replaced with the ice cutter shaft 51, that is, the driving mechanism 30 drives the ice cutter shaft 51 to rotate, whereas the ice bank 12 is fixed relative to the housing 11. Since the ice crushing manner in which the driving mechanism 30 drives the ice cutter shaft 51 to rotate whereas the ice bank 12 is fixed relative to the housing 11 is of the prior art ( CN105509391A ), it will not be described in detail any more here.
