Abstract

The present invention relates to a kind of gas burner control device, comprising a power supply unit (2) used to supply the electric power required during the operation of the gas burner control device, a flame detection unit (3) that is arranged near the flame ring of the gas burner and is used to transmit the detected message about the burning status of the gas burner to the logic control circuit (1) that will be mentioned later, a valve control unit (4) arranged in the gas supply passage inside the gas switch base (cock) and controlled by the logic control circuit (1) to open or close mechanically to determine whether the gas is supplied, and a logic control circuit (1). Besides, the gas burner control device at least has one set of control panel with a LCD panel used to display the setting and operation status, and several operation push buttons and switches used to be the input interface to control and set the logic control circuit (1), a time control unit (13) having a clock unit and a counter unit with several independent timer settings and capable of driving the said valve control unit (4) to block the gas supply passage, and a flame signal process unit (14) that can logically analyze the signal detected by the said flame detection unit (3). When the burner flame is under normal condition, the valve control unit (4) is controlled to keep the gas supply passage unobstructed. When the burner blaze has gone out abnormally, the valve control unit (4) is controlled to keep the gas supply passage blocked. By the detection for the gas burning condition or the settings of the time control circuit, the gas supply valve is controlled to open or close to promote the safety and convenience of the gas burner operation.
