Abstract
A door opening/closing device for an ice dispenser is disclosed. The door opening/closing device includes a DC motorwhich is rotated in forward and reverse directions, a 2-staged spur gearmeshed with a worm gearinstalled on a driving shaft, a 3-staged spur gearmeshed with the 2-staged spur gear, and a fan-shaped output gearmeshed with the 3-staged spur gearand rotated in forward and reverse directions by interconnection of the motorand the gearsand. If the output gearis rotated in the forward direction, a rod-shaped bosspushes and rotates a link leverto press a coil springwound around an opening/closing linkand thus open a door. If the output gearis rotated in the reverse direction, the coil springis released from a pressurized state, and the rod-shaped bossrotates in the reverse direction while abutting against the link lever, so that the dooris closed without generating impact and sound.
