Kind Code:
A2
Abstract:
The present invention relates to a device for assisting the rotation of a door, which supports a door that rotates to be opened/closed. More particularly, the present invention relates to a device which elastically supports a closed door by means of an elastic member thereof, so as to enable the door to be easily opened, and which simultaneously provides a no-load area by means of the elastic member being uncompressed during the early stage of a door closing operation so as to enable the door to be easily closed. The present invention comprises: a hinge shaft fixed onto the main body of an appliance to support the rotation of a door; an elastic member, one end of which is fixed at the hinge shaft and the other end of which is compressed or released in accordance with the rotation of the door; and a restriction member which compresses the elastic member at a predetermined rotation angle of the door when the door is closed, such that elastic force can be accumulated in the elastic member between the position in which the door is opened at a predetermined angle and the position in which the door is closed.
