ABSTRACT:
A refrigerator includes a door hinged to a housing, and a door opening/closing assist device which aids in opening and closing the door. The device includes a spring-biased roller carried by the door and a guide plate carried by the housing. The guide plate forms a guide curvature against which the roller is elastically biased. The guide curvature is shaped so that during an initial stage of a door opening (or closing) movement the roller is displaced by the guide curvature to cause the spring to store energy, and so that during a final stage of the door opening (or closing) movement, the spring releases energy and forces the door to assist the performance of the final stage.
