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.

The present invention discloses a burner cap. The burner cap comprises a main body (1) with an annular wall (10), a plurality of first main fire holes (11) is defined on the upper layer, and a plurality of second main fire holes (12) is defined on the lower layer; the annular wall (10) has an annular groove (2), and the annular wall (10) also has a fire holding channel (21), which connects to the annular groove (2) and connects to the first main fire holes (11), and/or the second main fire holes (12). So that the burner cap can significantly improve the combustion efficiency of the gas range while holding the flame from the first and second main fire holes.

The present invention discloses a cooker burner. The cooker burner comprises a base (1), a first ejector passage (3), a plurality of primary air passages (4), a cap (5) and a transfer passage (6), the base (1) has a chamber (11) and at least one first ejector (12); the first ejector passage (3) has a central chamber (311) and a peripheral chamber (312), the peripheral chamber (312) is used for making primary air around the periphery of the central chamber (311) uniform. With the design of the first ejector passage, the gas in the central chamber is more directly mix with the primary air in the peripheral chamber, improving the mixing uniformity and air intake rate around the periphery of the central chamber. Therefore, yellow flame and backfire can be avoided.

A gas burner device includes an orifice holder including an orifice. The gas burner device also includes a burner body. The burner body includes a venturi tube arranged to receive a gas from the orifice and a burner port discharging the gas supplied through the venturi tube. The venturi tube includes a venturi inlet through which the gas that is jetted from the orifice flows in. The venturi tube also includes a venturi outlet through which the gas flowing in through the venturi inlet is discharged. The venturi tube further includes an acceleration part including a smaller diameter than the venturi inlet and the venturi outlet and includes a cylindrical shape.

A gas burner assembly is provided which includes an air pump that supplies a flow of air into a boost fuel chamber for mixing with a flow of boost fuel before being combusted and directed through a plurality of boost flame ports. An accumulator is positioned between the air pump and the boost burner such that the flow of air passes though the accumulator, thereby dampening pulsations or surges from the air pump before entering the boost fuel chamber.

A cooking appliance is provided, including a gas burner assembly for a cooktop floor of a cooking appliance. The gas burner assembly includes a burner body having a single combustion chamber and a plurality of flame ports in fluid communication with the single combustion chamber, a first mixing tube in fluid communication with the single combustion chamber and configured to supply a first air-gas mixture to the single combustion chamber, and a second mixing tube in fluid communication with the single combustion chamber and configured to supply a second air-gas mixture to the single combustion chamber.

A cooking appliance is provided, including a multi-level gas burner with a body having a lower burner section on a lower side and an upper burner section on an upper side. The lower burner section is separated from the upper burner section. The lower side of the body has a first injection point for receiving a first air-gas mixture for the lower burner section and a second injection point for receiving a second air-gas mixture for the upper burner section. The first injection point is partitioned from the second injection point thereby separating the first air-gas mixture from the second air-gas mixture. The body includes a passageway fluidly connecting the second injection point on the lower side of the body to the upper burner section on the upper side of the body.

A collapsible camp stove having a cover, a chassis having a fuel burner and a pot support; and the pot support and the chassis and the cover are all pivotally interconnected to one another in a parallelogram structure wherein pivotal opening of the cover relative to the chassis causes the pot support to raise upwardly away from a top surface of the chassis while the pot support continuously remains parallel to the top surface of the chassis.

A gas burner assembly for a cooktop appliance and a method for operating the same are provided. The gas burner assembly includes a normally aspirated primary burner, a concentrically-positioned forced air boost burner, a boost valve for regulating a flow of boost fuel to the boost burner, and a forced air supply source for providing a flow of air to the boost burner. The method includes activating the boost burner upon receiving a command and starting a timer. After a predetermined amount of time has passed, e.g., such as ten minutes, the boost burner is extinguished by closing the boost valve to prevent unsafe operating conditions.

A gas burner assembly and a method of operating the same are provided. The gas burner assembly includes a gas burner and a fuel regulating device for providing a flow of fuel to the gas burner to heat a cooking utensil. The method is a closed loop cooking method that includes monitoring the temperature of the cooking utensil and adjusting the power output of the burner accordingly to drive the utensil temperature to a target cooking temperature or profile. However, the burner power is limited to a maximum fuel flow rate, e.g., to ensure safe operation and to prevent the flames from the gas burner from engulfing the sides of the cooking utensil.
