Abstract:
A gas cooktop, comprising:at least one cooking zone having: a gas burner for receiving a gas supply and for distributing flames at a flame area; a flow adjuster fluidically connected to said gas burner and selectively supplying gas to said gas burner; a cooking vessel support; a sensing device for measuring a temperature of a cooking vessel placed on said cooking vessel support, said temperature sensing device having: an optical channel; and at least one infrared sensor for measuring temperature-dependent infrared radiation of the cooking vessel; a setpoint generator for setting a setpoint value; an electric circuit connected to said sensing device, to said setpoint generator, and to said flow adjuster, said circuit setting a level of the gas supply to said burner through said flow adjuster dependent upon said setpoint value received from said setpoint generator and dependent upon a measured temperature of the cooking vessel received from said sensing device; and a shielding disposed between said optical channel and said flame area, said shielding thermally separating said optical channel and the flames from one another.
