  • the support frame 20 is formed in a rectangular frame shape.
  • a mounting part 21 for being mounted onto the rear side of the door 4 is provided on the upper surface of one of the long sides of the support frame 20.
  • Support holes 23 for rotation of the ice tray 30 are formed in the short sides of the support frame 20.
  • a hooking threshold (not shown) is provided on one of the short sides of the support frame 20. The hooking threshold horizontally supports the ice tray 30, and simultaneously, allows the ice tray 30 that has rotated by a predetermined angle to be twisted. Since the hooking threshold is an obvious structure in a related art twisting type ice maker, detailed description thereof is omitted.
  • a stopper protrusion 25 is provided to one of the long sides of the support frame 20.
  • the stopper protrusion 25 allows the tray cover 40 to rotate in relative to the ice tray 30.
  • the front end of the stopper protrusion 25 is so located as to deviate from the rotation trace of the ice tray 30 but overlap the rotation trace of the tray cover 40. Therefore, the stopper protrusion 25 does not interfere with rotation of the ice tray 30 but interferes with rotation of the tray cover 40.
  • the ice tray 30 is formed in a rectangular shape corresponding to the inside of the support frame 20.
  • the ice tray 30 includes a plurality of ice cubes 31 storing water for making ice.
  • Rotational shafts 33 are provided to the short sides of the ice tray 30, respectively. Each rotational shaft 33 is inserted into and supported by the support hole 23.
  • the tray cover 40 substantially prevents the water stored in the ice cubes 31 from flooding into an outside.
  • the tray cover 40 selectively opens/closes the ice tray 30, more specifically, the ice cubes 31.
  • the tray cover 40
  • a water supply opening 41 is provided to the tray cover 40.
  • the water supply opening 41 is designed for storing water in the ice cubes 31.
  • the projection of the water supply opening 41 overlaps at least a portion of all the ice cubes 31.
  • a contact rib for selectively contacting the upper edge of the ice tray 30 is provided on the inner periphery of the tray cover 40.
  • the contact rib 43 protrudes from both ends on the inner periphery of the tray cover 40.
  • a height to which the contact rib 43 protrudes may be determined in a range that rotation of the ice tray 30 does not interfere with the contact rib 43.
  • the tray cover 40 is installed to rotate in relative to the ice tray 30.
  • one of the long sides of the tray cover 40 is rotatably connected to one of the long sides of the ice tray 30 by a rotation member 45 (refer to Fig. 5).
  • the long sides of the ice tray 30 and the tray cover 40 connected to each other by the rotation member 45 are the long sides of the ice tray 30 and the tray cover 40 that are separated from the stopper protrusion 25.
  • the rotation member 45 may be a hinge shaft provided to one of the ice tray 30 and the tray cover 40, and a hinge hole provided to the other of the ice tray 30 and the tray cover 40 to receive the hinge shaft.
  • control housing 50 is provided to the outer surface of one of the short sides of the support frame 20.
  • Various parts including a motor (not shown) for rotating the ice tray 30 are provided inside the control housing 50. That is, the ice tray 30 is rotated by driving force delivered from the motor.
  • FIGs. 5 to 8 are vertical cross-sectional views explaining an operating process according to an embodiment.
  • the ice cubes 31 store water for making ice.
  • the water W stored in the cubes 31 is delivered through the water supply opening 41. Therefore, a phenomenon that the water W is flooded into an outside by the tray cover 40 while the water W is supplied to the ice cubes 31 is prevented.
  • the water W stored in the ice cubes 31 is frozen by cooling air circulating through the freezing chamber 2 (refer to Fig. 2), so that ice is made.
  • the ice tray 30 starts to rotate counterclockwise around the rotational shaft 33 using driving force from the motor.
  • the tray cover 40 also rotates counterclockwise around the rotational shaft 33 when seen from the drawing in cooperation with the ice tray 30.
  • the ice tray 30 rotates counterclockwise by a predetermined angle
  • one of the long sides of the tray cover 40 rotating in cooperation with the ice tray 30 is closely attached on the stopper protrusion 25.
  • rotation of the tray cover 40 that operates in cooperation with the rotation of the ice tray 30 interferes with the stopper protrusion 25.
  • ice tray 30 is closely attached on the hooking threshold, and thus the ice tray 30 is twisted, ice I made from the ice cubes 31 is separated from the ice cubes 31.
  • the separated ice I falls down due to its own weight and is stored in the ice bank 60 (refer to Fig. X).
  • FIG. 9 is a perspective view illustrating an ice tray and a tray cover forming an ice maker according to another embodiment.
  • a tray cover 40 for selectively shielding ice cubes 31 of an ice tray 30 rotating around a rotational shaft 33 is formed in a rectangular plate shape. At this point, the tray cover 40 may be formed in a size that can extend to the outside of the ice tray 30. Also, a water supply opening 41 for supplying water to be stored in the ice cubes 31 is formed in the tray cover 40. Since other elements of the embodiment of Fig. 9 are the same as those of the previous embodiment, detailed descriptions thereof are omitted.
  • an ice maker is mounted in a refrigerator door.
  • the ice maker prevents reduction in the storage capacity of a storage space of a refrigerator, so that a larger amount of food can be stored in the refrigerator.
  • a tray cover is provided to prevent water stored in an ice tray from flooding. Accordingly, a phenomenon that the water stored in the ice tray floods by an impact generated when a refrigerator door is opened/closed is prevented, so that a refrigerator can be used more cleanly.
  • an ice bank storing ice can be taken in and out by opening a home bar door without opening a refrigerator door. Accordingly, the ice can be taken out more simply.
