Abstract
The range has one or more burners. Above these is arranged a glass-ceramic plate. Each burner has a perforate ceramic element that is spaced from the plate by a distance just sufficient to permit the combustion gas to travel through this space. A thermal securing arrangement detects the temperature of the plate, and an adjusting arrangement permits adjusting of the burners, and therefore of the plate, to a plurality of different temperature levels.
Claims24
A gas range, comprising an upper glass-ceramic plate;
- at least one burner below said glass-ceramic plate and including a perforated ceramic element spaced from said plate by substantially 10-15 mm;
- thermal sensor means for sensing the temperature of said plate;
- gas supply means for said burner including control means for periodically activating and deactivating said gas supply means in dependence upon the temperature of said plate sensed by said thermal sensor means;
- and adjusting means for adjusting the temperature of said plate to a plurality of different temperature levels.
1 more element
A gas range as defined in clam 1;
- further comprising a closed air-supply space below said burner and provided with at least one upright shaft for ambient air, said burner being adapted to draw combustion air from said space by a gas injector.
