A multiple burner cooking assembly for portable cooking includes a table and a plurality of burners that is each of the burners is coupled to the table for having a cooking pot positioned thereon for cooking. A plurality of conduits is each of the conduits is coupled to the table and each of the conduits is fluidly coupled to a respective one of the burners. A plurality of valves is each fluidly coupled to a respective one of the conduits and each of the valves is in fluid communication with a respective one of the burners. A supply hose is fluidly coupled to the plurality of conduits and the supply hose is attachable to a fuel source to deliver the fuel in the fuel source to the conduits.

A gas collapsible stove includes an expandable combustion chamber formed from nested annular rings that can collapse to about the height of a single ring and expand into a combustion chamber for burning combustible materials. Ventilation holes at the bottom of the combustion chamber provide airflow into the combustion chamber. The combustion chamber is frustoconical and narrows at the top which increases air flow into the combustion chamber via the Venturi effect. Combustible fuels can be added and ignited in the combustion chamber and cookware containing food can be placed onto an associated top plate suspending the combustion chamber. A gas head with a plurality of gas apertures can be inserted through a bottom plate secured to the bottommost annular ring to allow a combustible gas to be used as a combustible fuel in the combustion chamber.

An eductor for a gas burner includes a mixing body that defines a mixing chamber. The mixing body also has a fuel line coupling. The mixing chamber is configured for receiving a flow of forced air and a flow of fuel. The fuel line coupling is configured for supporting a fuel line through which the flow of fuel enters the mixing body. A fuel metering orifice is mounted to the mixing body. The fuel metering orifice is spaced from the fuel line coupling on the mixing body. The fuel metering orifice is configured for directing the flow of fuel into the mixing chamber of the mixing body. The fuel metering orifice is separable from the mixing body when the fuel line is coupled to the mixing body at the fuel line coupling.

A domestic cooking appliance includes: a main housing; a cooking compartment; a gas burner that provides heat to the cooking compartment; a cooling air passageway located between the cooking compartment and a rear wall of the main housing, the cooling air passageway being separated from the cooking compartment by a rear wall of the cooking compartment; and a gas flue. The gas flue has an exhaust gas inlet open to the cooking chamber, the exhaust inlet being located in a lower panel of the gas flue, a cooling air inlet open to the cooling air passageway, an outlet located above the exhaust gas inlet, above the cooling air inlet, and above an uppermost portion of the cooking compartment, and an upper deflector located above the outlet and angled relative to vertical at a non-zero first angle such that the upper deflector extends over at least a portion of the outlet.

A gas cooker includes a housing delimiting an upper and a lower compartment divided by a plate and communicating through slits formed in the plate; a hob having a plurality of burners; an oven housed in the lower compartment and having a front opening, a pivoting door selectively closing the lower compartment, and a grill device; a front panel having controls elements connected to the burners and the oven; and an exhaust path for fumes and combustion products of the oven. The gas cooker further includes a folded metal sheet disposed in the upper compartment by the slits and having lateral edges contacting the plate to define a conduit between the slits and the exhaust path, and separate the exhaust path from the rest of the upper compartment which houses the control element, so as to prevent the control elements and the front panel from overheating.

A gas cooker that includes a case defining an interior area, the case including an opening to the interior area; a plate covering, fully or in part, the opening of the case; a burner that is located in the interior area of the case, wherein the burner includes a heating element that is heated using gas; a vent that is located at a first position of the case and that is configured to discharge burned gas from the interior area of the case to an exterior of the case; an insulating case that is coupled to the burner and that is configured to hold the burner; and a first insulator that is coupled between the insulating case and the plate and that is configured to seal an interior space of the burner is disclosed.

A heat exchange system for commercial kitchen installations, having a dedicated plenum to receive combustion emissions separate from cooking emissions, where the plenum has a heat exchange structure that efficiently and directly draws heat from the combustion emissions. The plenum heat exchange structure reduces the air volume that a ventilation hood covering the kitchen appliances needs to process and filter, while concurrently obtaining heat from combustion emissions without interference from cooking emission effluents such as grease, smoke, or particulate matter. Heat drawn out of the combustion emissions can be stored in a thermal reservoir for powering other parts of the commercial kitchen or other uses. The diverted airstream from combustion emissions, once passed through the heat exchange structure, can further ventilate through an additional heat exchanger, to provide tempered air to an interior location, such as the commercial kitchen via an air supply duct in the cooking emission ventilation hood.
