Abstract
A gas surface range having a downdraft ventilation system with automatic shut off during ignition. A relay is activated by current flowing to the spark coil of the electrical igniter, and has contacts connected in series with the blower motor of the downdraft system. Thus, the downdraft system is disabled during attempted ignition, and is automatically enabled at the completion of ignition.
Claims14
A gas fueled appliance comprising:
- a gas burner;
- an electrical igniter for igniting said gas burner;
- means for actuating said electrical igniter;
- exhaust means for forcing a flow of air past said gas burner to remove cooking effluents;
- and
- means responsive to actuation of said igniter for disabling said exhaust means.
A gas surface range comprising:
- a cooktop surface;
- at least one surface gas fueled burner mounted in an opening in said cooktop surface;
- an electrical igniter for igniting said gas fueled burner;
- means for supplying a flow of electrical current to said igniter to actuate said igniter;
- a down draft duct having an air inlet disposed adjacent to said gas fueled burner at substantially the same level as said cooktop surface;
- a blower coupled to said duct and operable to draw air across said cooktop surface and down into said duct to remove cooking effluents from the region of said range;
- and
- a switch connected in series with said blower and responsive to current flowing to said igniter to disable said blower during igniting of said gas fueled burner.
In a gas surface range having a down draft ventilator adapted for drawing air across a cooktop surface of the range past a burner and a corresponding electrical igniter to a duct having an intake adjacent the cooktop, a method comprising the steps of:
- activating the ventilator to draw the air;
- and
- disabling the ventilator in response to actuation of said igniter.
