A door opening/closing device for an ice dispenser is disclosed. The door opening/closing device includes a DC motor 1 which is rotated in forward and reverse directions, a 2-staged spur gear 3 meshed with a worm gear 2 installed on a driving shaft, a 3-staged spur gear 4 meshed with the 2-staged spur gear 3, and a fan-shaped output gear 5 meshed with the 3-staged spur gear 4 and rotated in forward and reverse directions by interconnection of the motor 1 and the gears 2, 3 and 4. If the output gear 5 is rotated in the forward direction, a rod-shaped boss 5a pushes and rotates a link lever 6a to press a coil spring 8 wound around an opening/closing link 6 and thus open a door 7. If the output gear 5 is rotated in the reverse direction, the coil spring 8 is released from a pressurized state, and the rod-shaped boss 5a rotates in the reverse direction while abutting against the link lever 6a, so that the door 7 is closed without generating impact and sound. |
