A double flow rate gas solenoid valve has an inlet and at least a first outlet in a housing. First and second solenoids are selectively operable relative to first and second valve seats to establish first and second gas flow paths, respectively. The second flow path has a restriction thereby resulting in a lower gas flow rate through the second flow path than the first flow path. When connected to a common inlet of a burner, at least two, if not three flow rates can be provided by the valve.

The present disclosure relates to a cooking apparatus including a heating device, a gas passage to guide gas supplied from the outside to the heating device, a gas valve configured to supply gas to the gas passage, a modulating valve configured to adjust the degree of opening of the gas passage, a boosting passage formed to be branched from a first portion of the gas passage and joined to a second portion of the gas passage positioned in the rear of the first portion along a direction in which gas in the gas passage flows, a boosting valve configured to open and close the boosting passage, a first nozzle disposed between the first portion and the second portion of the gas passage, and a second nozzle disposed between the second portion of the gas passage and the heating device.

Portable grills are disclosed. An example portable grill includes a frame, a leg unit, and a leg latch assembly. The leg unit is coupled to the frame. The leg latch assembly includes a post rigidly coupled to the leg unit, and a swing plate pivotally coupled to the frame. The swing plate includes an opening to receive the post when the portable grill is in a collapsed configuration. The opening includes a first post-receiving portion having a first diameter, and a second post-receiving portion having a second diameter less than the first diameter. The swing plate is pivotable to selectively locate the post in the first post-receiving portion or the second post-receiving portion. The swing plate is separable from the post when the post is located in the first post-receiving portion, and inseparable from the post when the post is located in the second post-receiving portion. The leg latch assembly latches the leg unit in a fixed position relative to the frame when the post is located in the second post-receiving portion, and unlatches the leg unit from the fixed position when the post is located in the first post-receiving portion.

A regulator assembly is disclosed. The regulator assembly can include a regulator having a gas inlet and a gas outlet. The regulator assembly can also include an extension pipe having a proximal end and a distal end. The regulator assemble can also include an orifice disposed in the extension pipe for modification of the gas flow.

Portable grills are disclosed. An example portable grill movable between an erected configuration and a collapsed configuration includes a frame and a leg unit coupled to the frame. The leg unit includes a first leg, a second leg spaced apart from the first leg, and a support bar coupled to and extending between the first and second legs. The support bar further extends at an angle away from the first and second legs. The support bar is configured to contact an underlying surface to support the portable grill when the portable grill is in the collapsed configuration and oriented horizontally relative to the underlying surface. The support bar is further configured to provide a handle by which the portable grill can be hung when the portable grill is in the collapsed configuration and oriented vertically relative to the underlying surface.

Example dual-burner assemblies for cookboxes of gas grills are disclosed. An example dual-burner assembly includes a first burner tube and a second burner tube. The first burner tube has a first maximum heat output. The second burner tube has a second maximum heat output. The second burner tube is spaced apart from the first burner tube by a distance of no more than 0.750 inches. The second maximum heat output is less than the first maximum heat output.

A gas valve for a cooking appliance is provided and includes a valve housing defining a valve chamber therein. A plug is disposed within the valve chamber. A valve stem interacts with the plug such that rotation of the valve stem correspondingly rotates the plug to selectively permit a flow of gas through the gas valve. The valve stem is axially translatable between a locked position wherein rotation thereof is inhibited and an unlocked position wherein rotation thereof is permitted. A first spring exerts a compressive force against the valve stem, toward the plug, to bias the valve stem into the locked position. A second spring exerts a compressive force against the plug in order to seat the plug within the valve chamber regardless whether the valve stem is in the locked or the unlocked position.

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.

A method of controlling a gas furnace comprising a gas valve for supplying a fuel gas to a manifold; a burner through which the fuel gas discharged from the manifold passes; an igniter for igniting a mixture of fuel gas passed through the burner and air; and an inducer for generating a flow in which a combustion gas generated by the burning of the mixture is discharged to an exhaust pipe via a heat exchanger, wherein the gas furnace performs a heating operation according to a heating signal or a heating stop according to a stop signal, includes the steps of: (a) receiving any one of the heating signal or the stop signal; (b) transmitting a signal to operate the inducer when the heating signal is received; (c) operating the igniter; (d) transmitting a signal to open the gas valve; (e) detecting whether the gas valve is opened or closed; (f) detecting a flow rate of the fuel gas in the manifold; and (g) displaying a normal operation of the heating operation, based on information detected in the steps (e) and (f).

A gas grill is disclosed having a gas control valve with a push to sear feature. The gas control valve has a housing with a valve core rotatably disposed within the housing. A sear valve is disposed within the valve core. A user rotates the valve core within the housing to selectively align a gas inlet port with an inlet passage and to align a sear gas port and a sear gas flow passage. The sear valve has a sear valve element which is selectively movable relative to the valve core to selectively pass a sear gas through a sear gas port and a sear flow passage to the forward end of the valve housing, and then to the grill. A bias member, preferably a coil spring, is mounted between the sear valve element and the valve core for urging the sear valve element to a closed position.
