A cooking range in which a burner below a glass-ceramic plate is ignited with a glow igniter switched off in response to an ionization detector when combustion products are effected so as to prevent excessive heating of the glow igniter.

Cooking apparatus with at least one glass-ceramic cooking plate

The invention is concerned with a cooking range, especially suitable for mobile homes, which utilizes gas burners, where the exhaust gas draft is held substantially constant and the exhaust duct temperature is kept below a critical temperature by providing temperature-regulated cool air openings on the exhaust gas duct. Reliable regulation is accomplished by closures controlled by bimetallic springs positioned in a swivelable manner in the cool air openings so as to act on the closure flaps, and the closure action further improved by restoring springs exerting pressure on the outside of the closures.

Cooking range

Gas range with at least one burner covered by a glass ceramic plate, wherein the burner has a gas cock and a timed-ignition and monitoring device, such that the output of the burners is adjustable. A gas cock is used with plugs rotatable between a high and a low position with the aid of a knob and a knob shaft, with a spindle connected to the knob shaft, with a valve plate under the gas inlet opening in the plug housing, with a microswitch for the ignition device and with the use of an electromagnet under the valve plate, in the area of the gas supply connection of the further housing. The knob with the knob handle and the spindle is pressable against the action of a return spring in the high position of the plug. This way, the microswitch for the timed ignition device becomes actuatable and the valve plate becomes pressable on the electromagnet against the action of a return spring, thereby opening the combustion gas inlet opening. The monitoring device has thermoelement reaching deeply into the flame of the burner, which generates a thermal current after maximum 10 sec., feeding the electromagnet and holding the valve plate. The design of the thermoelement and of the electromagnet are such that the electromagnet releases the valve plate and interrupts the gas supply when the flame of the burner is interrupted for up to 60 sec. or for more than 60 sec.
