A cooking device is provided. The cooking device includes a frame that forms a cooking chamber; a burner provided inside the frame and having a plurality of gas outlet holes; an ignition unit provided inside the frame to ignite a mixed gas discharged from at least one of the plurality of gas outlet holes; and a fixing device to affix a position of the ignition unit with respect to the burner.

Disclosed is an outdoor portable gas stove, which includes a stove cover, a burner, a gas pipeline, an ignition device and a flame-out protection device. The burner is arranged in the stove cover, an annular gas passage is formed in the burner, a gas outlet and combustion hole is defined on an upper end face of the burner, and the gas outlet and combustion hole is communicated with the annular gas passage. The ignition device is arranged above the gas outlet and combustion hole and is configured for igniting gas. The gas pipeline is communicated with the annular gas passage, and a control valve is arranged on the gas pipeline. The flame-out protection device is arranged above the gas outlet and combustion hole and connected with the gas pipeline. The technical proposal of the present application can realize an overall control of gas supply.

A system for igniting a grill can include a solenoid valve, a flame rectification sensor, an igniter, and a control circuit connected to the solenoid valve and the flame rectification sensor. The solenoid valve controls flow of gas to the grill's burner and includes a switch that closes when a handle connected to the switch opens the solenoid valve. The control circuit sends current to the solenoid valve when the switch is closed to hold the solenoid valve open. After the switch closes, the igniter is ignited. After ignition, the control circuit monitors the presence of a flame with a flame rectification sensor. If no flame is detected after a certain amount of time, the control circuit stops sending current to the solenoid valve to close the solenoid valve.

This application provides a gas stove temperature-control system, the gas stove with the same and a method for controlling temperature of the gas stove. The gas stove temperature-control system including a power board and a rechargeable battery supplying power to the power board further includes: a stove cover limit switch connected to the power board; a gas valve connected to the power board; an electromagnetic valve connected to the power board and the gas valve; an ignition pin connected to the power board; a burner connected to the gas valve and the ignition pin and; and a thermocouple connected to the power board.

A gas burner assembly for a cooktop appliance includes a flame ring comprising a plurality of flame ports arranged in an annular array. An outer ring and an inner ring collectively define each flame port of the plurality of flame ports. The outer ring and the inner ring are concentrically aligned and concentrically mated. As a result of this arrangement of the outer ring and the inner ring, the plurality of flame ports are defined by the outer ring and the inner ring. The plurality of flame ports extend radially between the inner ring and the outer ring.
