Abstract

PURPOSE:To alarm boiling of hot water and to enable to perform an efficient cooking operation, by a method wherein an output of a sound collector, positioned facing and opposite to a cooker, is selected and amplified. CONSTITUTION:If a cooker 1 is set to start heating, a thermal lead relay 10 actuates to supply a current to a circuit. A given boiling sound is obtained through a sound collector 11, and when a comparator 15 decides that it exceeds a given amount, an input of a center of a gate circuit 20 goes to a H-level. After a given time has elapsed, the H-level is outputted from a delay circuit 17, an oscillating circuit 19 actuates by means of the output of the gate circuit 20. This causes a transistor 23 to repeat a turning-ON and turning-OFF operation to activate a sounding body 22.
