Abstract
The present invention provides an improved alarm device which automatically starts accumulation of a heating amount when food items are placed into a cooking liquid and outputs an end-of-cooking signal when the accumulated heating amount reaches a predetermined value. This system makes an operator free from troublesome manual operation as pressing a start pad simultaneously with placing food items into the cooking liquid. The alarm device controls a cooker to start forcible heating irrespectively of its combustion conditions simultaneously with starting accumulation of the heating amount. The system of the invention prevents an undesirable time lag between substantial drop in temperature of the cooking liquid and start of heating and efficiently reduces the temperature fall due to cold food items, thus allowing food items to be cooked desirably.
