Abstract
A ventilating hood and cooktop system includes safety components to reduce or eliminate the possibility of a fire in the ventilating hood. The system provides elements for sensing the temperature over the cooktop. When the temperature reaches a first predetermined level, the ventilation fan speed is increased. The system includes alarm warning elements which issue different signals depending on the temperature above the cooktop. If a maximum temperature is reached, the system shuts off the fan of the ventilating hood and shuts down the cooktop.
