HEATING COOKING APPARATUS WITH WEIGHT DETECTING FUNCTION

摘要

PURPOSE:To reduce the effect due to the instrumented error caused by the difference in the position of a foodstuff to be heated and enable to perform the safe heating cooking by a method wherein a part of a tray on which the foodstuff to be heated is placed with high frequency by an operator is conformed to a part having less position difference by arranging the Roberval's mechanism. CONSTITUTION:The Roberval's mechanism is provided for maintaining the both ends of plural plate springs 1 under the parallel condition with pinching a fixing member. The fixing member is arranged between a heating chamber 4 and the bottom part of a main body 5, the fixing member side of one end thereof is faced to the opening side of the heating chamber 4 for facing to an opening for taking-in and out of the foodstuff to be heated, the fixing member side of the other end thereof is positioned at the wall surface side opposing to an opening of the heating chamber. Either side of the fixing member supports a fixing end, while the other side supports the tray 11 and made to be freely movable in accordance with the weight of the foodstuff to be heated placed on the tray. By detecting the movement, the weight of the foodstuff to be heated is calculated.
