Abstract
An ice discharging apparatus of an ice dispenser comprises an openable door normally urged resiliently to a closed state by means of a torsion coil spring and adapted to be openable by a door actuator under the control of a control apparatus. The torsion coil spring includes an intermediate coil portion substantially of a cylindrical form and at least one end coil portion having an inner diameter greater than an average diameter of the intermediate coil portion in the unloaded state. The torsion coil spring has at least one arm extending from an end of the coil spring and having an extension secured in contact with a stationary part of the apparatus or a part of the openable door at an intermediate portion thereof and subsequently bent to constitute an inactive portion in which an annular mounting member for mounting the torsion coil spring is formed at the free end thereof. The torsion coil spring includes at least one annular portion formed at an end of an arm extending from the spring, the annular portion being linked to an anti-drop wire ring member mounted on a stationary part of the ice discharging apparatus or on the openable door. The torsion coil spring is difficult to break. Fragments resulting from breakage is prevented from dropping into ice being discharged.
