A cooktop and appliance is provided that may include a first hob zone having a fixed gas receptacle, a first interchangeable burner, a second interchangeable burner, and a first gas flow switch. The first interchangeable burner may be selectively positionable at the first hob zone and define a fuel output area. The second interchangeable burner may also be selectively positionable at the first hob and may define a fuel output area smaller than the fuel output area of the first interchangeable burner. The first gas flow switch may be disposed at the first hob zone to selectively engage one of burners. The first gas flow switch may include a valve upstream of the fixed gas receptacle to selectively restrict gas flow upon engagement of the first gas flow switch with one of the first interchangeable burner or the second interchangeable burner.

The invention relates to a barbeque gas burner assembly (1) comprising inner (2) and an outer (3) gas burners and inner (3) and outer (5) heat directing shields, wherein the inner burner (2) is located within a boundary defined by the outer burner (3) and in a spaced-apart relationship thereto; the outer heat-directing shield (5) comprises a collar (21) with an outwardly extending rim (23) at one end thereof that is angled away from the collar (21), with the collar (21) and rim (23) complimentary shaped and sized to the outer burner (3) for the rim (23) to be supportable by the outer burner (3); the inner heat-directing shield (4) comprises a collar (24) that is complimentary shaped and sized to the inner burner (2) to be supportable thereby, and the collar (24) includes an outwardly extending rim (26) at one end thereof that is angled away from the collar (24); operatively for the rim (23) of the outer heat-directing shield (5) to be supported by the outer burner (3) with the collar (21) extending upwards from the outer burner (3), the inner heat-directing shield (4) to be located within the collar (21) of the outer heat-directing shield (5) with the collar (24) of the inner heat-directing shield (4) supported by the inner burner (2) to define an annular heat directing channel between the inner (4) and outer (5) heat-directing shields and to at least party shield each of the inner (2) and outer burners (3) against falling food debris.

An orifice holder includes a body that defines an inner chamber and inner wall portions. The inner wall portions each have a first width that is defined relative to the upper portion of the body. A first cup extends outwardly from the inner wall portions. A second cup extends outwardly from the inner wall portions and interconnects with the first cup through the inner wall portions. An airflow path is defined to the inner chamber from the first and second cups.

A fire pit apparatus is provided. The fire pit apparatus includes an enclosure; a burner assembly comprising a burner, wherein the burner is positioned on or at least partially within the surface of the enclosure; at least one control assembly; an elongate hollow member extending from the burner assembly to a distal end, the elongate hollow member being operatively and fluidly connected to the burner assembly and control assembly; and wherein, the enclosure defines a first aperture and a first compartment and a second aperture and a second compartment, wherein the first aperture provides access to the first compartment and the second aperture provides access to the second compartment and wherein the second compartment defines a third aperture that provides access to the first compartment.

A six-burner cooktop has front and rear heat sources on a left side, front and rear heat sources on a right side, and front and rear heat sources in a middle between the left side and the right side. A maximum power output of the rear middle heat source is greater than maximum power outputs of the left side and right side heat sources, and a maximum power output of the front middle heat source is less than the maximum power outputs of the left side and right side heat sources.

A method and apparatus for a gas burner head with at least a first burner region and a second burner region, an ignitor located near the gas burner, and a burner drive that is configured to generate relative rotation between the first and second burner regions of the gas burner to transfer a flame between the first and second burner regions during the relative rotation.

A gas-powered oven includes a cooking surface and a heat deflecting frame, such that the cooking surface and heat deflecting frame collectively define at least a portion of a cooking chamber. An outer housing extends around the cooking surface and the heat deflecting frame, with the outer housing having an opening formed therein and in communication with the cooking chamber. A first burner is connectable to a gas source and is located within the outer housing and spaced from the cooking chamber. The first burner is elongate and includes a first array of openings formed therein. A second burner is connectable to the gas source and extends into the cooking chamber toward a portion of the heat deflecting frame. The second burner includes a tapered passageway and an expanding passageway downstream of the tapered passageway to achieve desired flow characteristics of the gas flowing through the second burner.

A kiln includes a stage, a stove, a gas supply assembly, and a combustion device wherein, the stage includes a stage body and a carrier member. The stage body has a first chamber, while the carrier member is detachably disposed at the stage body. The stove is joined to the stage body and has an entry and a second chamber. The gas supply assembly is disposed at the stage body, and part of the gas supply assembly is located in the first chamber. The combustion device is located in the second chamber. The carrier member can be detached from the stage body and be moved out of the stove from the entry so that the first chamber communicates with the second chamber. In this way, the working space inside the kiln can be increased, which is convenient for users to repair and maintain the gas supply assembly or the combustion device.

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.
