ABSTRACT:
A food warmer (10) has a cover (14) hinged on a frame (11) by means of opposing side hinges (16,17,18,19,22,23) for rotating it around an axis of rotation between a closed position and a fully open position. At least one of the S hinges comprises coupling means (16,18) between the cover and the frame which rotate integrally with the cover against the action of reaction means (20) mounted on the frame. In this manner the action of the reaction means supplies virtual balancing of the moment produced by the weight of the cover.
