A cooking appliance has a multi-section cooking surface that is expandable to provide a larger depth cooking surface by slideably extending a moveable front burner section of the cooking surface. The cooking appliance includes a base section extending below the cooking surface, the base section providing structure and physical support for the cooking surface. The cooking appliance includes a multi-sectioned cooking surface having a stationary rear burner section and a movable front burner section. The stationary rear burner section includes at least one rear/back burner, and the moveable front burner section includes at least one front burner. The moveable front burner section translates/slides forward away from the stationary rear burner section to provide additional/larger separation spacing between the at least one rear burner and the at least one front burner. A block insert panel is inserted into the space created between the rear burner section and the extended front burner section.

A gas burner for a household cooking appliance includes a burner casing including a plurality of mixture outlet openings configured to guide out, during operation of the gas burner, a mixture of combustion gas and primary air into an area surrounding the gas burner for producing a burner flame. A mixture distribution chamber evenly distributes the mixture of combustion gas and primary air to the mixture outlet openings. Fluidly connected with the mixture distribution chamber is a storage chamber for storing, during operation of the gas burner, part of the mixture of combustion gas and primary air. The storage chamber includes an ignition flame opening configured to guide out the mixture of combustion gas and primary air that is stored in the storage chamber into the surrounding area for producing an ignition flame.

A gas burner includes a base with a first body and a raised annular band on an upper surface of the first body. A flange is formed about an outer periphery of the first body wherein the raised annular band and the flange define a first annular recess therebetween. A first notch is formed in a lower surface of the first body and extends through the flange and communicates with the first annular recess. The first notch is adapted to accommodate spark ignitor therein. A slot is formed in the raised annular band. A first cap includes a peripheral side wall having a distal end dimensioned to be received within the first annular recess. A gap between the distal end and a bottom wall of the first annular recess when the first cap is received therein provides fluid communication between the slot and the first notch.

A gas burner assembly includes a gas burner. A grate with a plurality of fingers is positioned above the gas burner. A sensor finger of the plurality of fingers defines an open downward facing slot at a bottom of the sensor finger. A temperature sensor is mounted to the sensor finger at a first end portion of the slot. A pogo pin terminal block is mounted to the grate at a second end portion of the slot. A wire extends between the temperature sensor and the pogo pin terminal block within the slot.

A burner assembly includes a spreader and a burner cap coupled to the spreader. The burner cap includes a sheet metal base bounded by a peripheral lip and a sheet metal top extending over the sheet metal base to define a gap and having a peripheral rim that wraps about at least a portion of the peripheral lip. The sheet metal base defines at least one port configured to allow air to flow into and out of the gap.

A burner of a gas stove includes a burner body, a partition member, and at least one flame cover. The burner body includes an inlet portion and a base. The inlet portion has at least one inlet passage for injecting gas and air, and the base has at least one mixture passage for mixing the gas and the air. The at least one mixture passage communicates with the at least one inlet passage. The partition member has a plurality of through holes and covers the at least one mixture passage. The at least one flame cover has a plurality of flame holes and covers the partition member. Whereby, the size of the burner of the gas stove could be reduced significantly, and the gas could mix with the air effectively and uniformly.

A gas hob comprising a top sheet, a port, a gas burner arranged on the top sheet and releasably connected to the port, the port being configured to supply the gas burner with fuel gas, and an extraction unit configured to extract fumes, the extraction unit being retractable into the top sheet.

A burner assembly for a cooktop comprises a spreader comprising (i) a central portion through which an axis extends, the central portion with a bottom surface, (ii) a plurality of apertures through the spreader, the plurality of apertures disposed further away from the axis than the central portion, and (iii) a ridge projecting from the bottom surface, the ridge disposed further from the axis than the central portion but closer to the axis than the plurality of apertures.

A tabletop cooking assembly for preparing foods thereon includes a burner element, a pan surrounding the burner element, a grill adjacent to the burner element, and an exhaust plenum adjacent to the grill having a plurality of apertures for drawing smoke away from the grill and an outlet for exhausting smoke therefrom. The exhaust plenum forms a defined volume around the grill to draw the smoke into the exhaust plenum and away from the grill such that the smoke does not pass through the grill or about the burner element. An exhaust duct and at least one filter assembly having at least one filter disposed therein are in fluid communication with the exhaust plenum for filtering grease. The subject invention also includes a blower for exhausting the smoke from the exhaust duct to an area outside of and immediately adjacent to the tabletop cooking assembly.

A grill for cooking food with a down firing burner affixed to the interior of the lid, above the food cooking surface. Below the food cooking surface is a clear panel that is easy to clean and may include a drain. There is no heat source below the cooking surface. Mechanical or electronic sensors automatically reduce the burner output when the lid begins to open or the handle is grasped anticipating that the lid is about to be opened.
