Abstract

The reheating time required by the oven depends partly on the weight and is determined by use of a weighting platform within the oven cavity. The microwave oven (12) has a door (14) through which access is gained to place the food dishes on a platform (16). This is mounted by suspension supports (22) onto a balance (20) external to the oven cavity. The cursor (24) of the balance displaces on a lever arm (26) to indicate the mass. The movement of the pointer from zero starts a motor by operation of a microswitch and the time of operation is determined by a cable displaced by the cursor. A disc (48) is rotated by a motor and returns to an initial position decided by the cursor and cable in the required time period.
