Patent ID: 8181477

Claim:
An ice making device comprising: an ice tray; a drive mechanism for moving the ice tray to a water-supply position where water is supplied to the ice tray and to an ice making position where the water in the ice tray is frozen; cooling bodies which are entered into the ice tray from an upper side of the ice tray at the ice making position to freeze the water; two guide plates which are disposed with a predetermined distance between the two guide plates and each of which is formed with a guide groove for guiding the ice tray to the water-supply position and to the ice making position; two engaging projections which are provided on the ice tray and each of which is engaged with one of the guide grooves; and two cranks, each of which is formed with a drive groove with which the engaging projection is engaged, and each of which is connected with the drive mechanism to be turned for moving the ice tray; wherein the water supply position is located at a position which is separated from the ice making position in a horizontal direction generally orthogonal to a vertical direction with respect to a normal operating position of the ice making device, and the two engaging projections are provided on the ice tray so that axial centers of the two engaging projections are substantially coaxial with each other, and a center of gravity of the ice tray is located below the two engaging projections; and wherein each guide groove includes a first groove part for guiding the ice tray in a downward direction from the ice making position and a second groove part connected with a lower end of the first groove part for guiding the ice tray in an upward direction to the water-supply position.
