Abstract

1418553 Electric cooker control systems J BARNETT 14 May 1974 [26 June 1973] 30287/73 Heading H2H An electric cooking apparatus is provided with means to indicate whether a hob element of the cooker has been inadvertently left energized after a utensil has been removed from the hob element. A hob element 11 of an electric cooking apparatus is provided at the centre thereof with a normally closed auxiliary switch 13, the switch coming into contact with a cooking utensil when such a utensil is placed on the element 11 to open the contacts thereof. Thus when a main switch 12 is closed to energize the element 11, a buzzer 32 and lamp 33 will only be energized if no utensil is on the hob and the switch 13, in consequence, closed. The buzzer 32 and lamp 33 may be used in conjunction with one or more hob elements, as shown at 11, 21.
