Gas burner system for a gas cooking hob

A gas cooking hob comprising:

• a gas burner having a plurality of flame ports;
• a pot support for supporting a pot at a distance above said flame ports of said gas burner;
• a supply air fan beneath said gas burner for generating an air flow toward the gas burner;
• a gas regulator for controlling a gas flow from a gas inlet to said gas burner;
• a thermocouple configured to detect flames emitted from said flame ports;
• a mixer unit configured to receive said gas flow from said gas regulator and at least a portion of said air flow from said supply air fan, and to deliver an air-gas mixture to said burner in order to yield said flames emitted from said flame ports;
• a controller operatively coupled to said thermocouple for receiving a flame signal therefrom indicative of the presence of said flames, to said supply air fan for controlling said air flow, and to said gas regulator for controlling said gas flow;
• said controller being adapted to operate said supply air fan in response to at least one of an automatic cooking program, detection that no pot is resting on said pot support, or a user input, in order to increase said air flow sufficiently to deflect said flames so that said flames are no longer detected by said thermouple resulting in said flame signal indicating an absence of said flames,
• wherein in response to said flame signal indicating said absence of said flames said controller actuates said gas regulator to turn off said gas flow from said gas inlet.
