US 2003/0192530 A1 · Method and apparatus for operating a gas-powered cooking and frying device

Abstract

A method and an apparatus for operating a gas-powered cooking device including an actuator for moving a closure disposed in the gas feed conduit of a burner to an open state and of igniting gas emitted from the burner by an ignition electrode to form a burner flame, the ignition electrode being connected to an ignition voltage for a predetermined first interval of time, a sensor thermo-conductively connected to the burner flame for generating a sensor voltage for maintaining the closure means in its open state if the sensor voltage attains a predetermined level and of initiating subsequent ignitions after a predetermined interval of time where the predetermined level is not attained within a predetermined further interval of time.

Dependent claims

Apparatus for operating a gas-powered cooking device, comprising:

actuating means for moving closure means disposed in a gas feed conduit of a burner to an open state;
an ignition electrode for generating an ignition spark for igniting a combustible gas mixture emitted by the burner to form a burner flame;
a sensor connected to the burner flame by heat conductance for generating an electric sensor voltage over a predetermined temporal course to maintain the closure means in the open state thereof;
a control unit for electrically connecting the ignition electrode to an ignition voltage for a predetermined first interval of time and provided with a first evaluation circuit for processing the sensor voltage to connect the ignition electrode to the ignition voltage in a response to a switching state dependent on the temporal course of the electric sensor voltage.
