A compact non-rotational mounting feature or mechanism is employed for mounting an orifice holder to a support member below a cooktop of a gas cooking appliance. More specifically, the holder and support member include interengaging polygonal structure, such as a key-shaped anti-rotational peg and hole combination, allowing the holder to be initially mated with the support member in a manner which prevents relative rotation and assuring that the holder is appropriately positioned for proper alignment of various gas burner components, such as an orifice, a gas line, electrode, flame spreader and other burner related structure. Upon exacting the positioning of the holder relative to the support member, the holder to fixed in position by a mechanical fastener.

A gas fireplace combustion device structure includes a simulated solid fuel and a combustor under the simulated solid fuel. The combustor has a fire exit hole facing the simulated solid fuel, a combustion air inlet passage under the combustor, and a specific slot at the combustor to define a third combustion air inlet. A partition is installed under the combustor; a second combustion air inlet leading to fire exit hole is formed between the partition and the combustor; the combustion air inlet passage is provided for supplying air to the second and third combustion air inlets; a combustion air slot is formed at the middle of the simulated solid fuel to resupply combustion air to the flame above the simulated solid fuel in order to achieve a two-time sectional combustion. This invention can control and resupply combustion air to the flames in different areas to improve the combustion effect.

A domestic cooking appliance for heating a food item includes a main housing; a cooking compartment in the main housing, the cooking compartment being configured to receive the food item to be heated, the cooking compartment having a first sidewall and a second sidewall; a gas burner that provides heat to the cooking compartment; a burner panel located between the gas burner and the cooking compartment; and a first fin protruding from the first sidewall and into the cooking compartment.

A switch assembly for controlling the ignition of gas burners of a cooking appliance having one or more gas valves. The switch assembly includes at least one first support member, operably couplable to a first gas valve, a spring biased ignition switch operably mountable to the at least one first support member, and an actuating member, having a longitudinal axis and operably couplable to at least the first gas valve between the at least one first support member and at least a control knob of at least the first gas valve. The actuating member is adapted to move between a first position, actuatingly engaged with the ignition switch, and a second position, actuatingly disengaged from the ignition switch, wherein the actuating member is moved towards the first position by at least the control knob, and back towards the second position by the spring biased ignition switch.

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 cooktop appliance includes a gas burner for receiving a cooking utensil and a fuel regulating device for regulating a flow of fuel to the gas burner. A controller receives a command to start a closed loop cooking process and confirms the cooking utensil by obtaining a first utensil identifier from the user and a second utensil identifier from the cooking utensil. If the first utensil identifier and the second utensil identifier match, the cooking process may commence. By contrast, if the first utensil identifier and the second utensil identifier do not match, the controller may stop the cooking process and notify the user.

A gas oven with stations under parallel or synchronous control includes a plurality of temperature sensors, a controller and a plurality of processing stations. An air intake device includes a throttle valve, a gas transmission pipeline and a main gas valve. The throttle valve includes a combined gas control unit and a gas valve controller. The air intake device further includes an external gas supply source, and the gas supply source is connected to the gas transmission pipeline and a bakeware. The main gas valve and the throttle valve are separately arranged on the main gas transmission pipeline. The plurality of processing stations are provided with a plurality of gas sub-transmission pipelines and throttle valve gas main transmission pipelines, respectively. The gas oven further includes a communication module connected to a remote control to control the oven by way of a remote terminal or a mobile phone app.

A control method of stepwise and stepless linear adjustment of a gas oven includes step 1: obtaining the setting temperature of the gas oven; step 2.: obtaining the temperature inside the gas oven; step 3: determining the low temperature threshold, high temperature threshold and preset flame level according to the setting temperature, wherein the high temperature threshold is greater than the low temperature threshold; step 4: ensuring the temperature inside the gas oven is between the low temperature threshold and the high temperature threshold; step 5: if it exceeds, determining the change trend of the temperature inside the gas oven; step 6: when the change trend of the temperature inside the gas oven rises or falls, adjusting the flame level of the gas oven to the preset flame level.

A combination microwave and cooktop has a transparent lid that is movable between a closed position where the lid overlays burners and an open position that exposes the burners. The microwave is located inside an enclosure that affixes the microwave through apertures in a bottom wall of the enclosure. A front trim bezel surrounds the front of the microwave and is affixed to the enclosure. Airflow for ventilation around the microwave is accomplished through vents in the rear wall of the enclosure and apertures in a top portion of the front trim bezel.
