Appl. No.:
6/238695
Inventors:

International Classification:
H05B 102
US Classification:
340568
Abstract:
An alarm system for use in a stove having a burner and control device for turning on and off the burner is provided, including an audio/visual alarm device and an alarm circuit for activating the alarm device. A low-voltage power supply energizes the alarm circuit. A sensor is mounted with the burner for sensing the presence and absence of a utensil thereon. A first switch in the alarm circuit closes a first set of contacts in response to the control device being in the burner-on position. A second switch in the alarm circuit closes a second set of contacts in the absence of a utensil on the burner, thereby completing the alarm circuit and activating the audio/visual alarm device.
