HIGH EFFICIENCY GAS COOKER Russian patent published in 2023 - IPC F24C15/10 F24C3/08 

FIELD: energy.

SUBSTANCE: invention relates to the field of energy. A household cooker comprises a frame on which a primary tube, one or more nozzles, one or more handles, one or more mixing tubes, one or more burner nozzles, one or more burner grates, one or more heat reflectors and a plurality of legs are installed. Each injector is fluidly connected to the primary tube to receive fuel and introduce fuel into the mixing tube at a controlled rate using each handle connected to the injector via an injector holder assembly. Each mixing tube is hydraulically connected to each injector for receiving injected fuel from the injector, wherein the mixing tube provides primary air entry through one or more slots and mixes the primary air with the injected fuel, and wherein the mixing tube modulates the pressure gradient of the air-fuel mixture through venturi, and the air-fuel mixture passes through the mixing tube towards the burner nozzle. Each burner nozzle is positioned coaxially above the mixing tube cap and is in fluid communication with the mixing tube, in which the burner nozzle contains a set of internal nozzles and external nozzles located on the circumferential surface of the burner nozzle to receive an air-fuel mixture from the mixing tube, in which the obtained the air-fuel mixture is ignited for combustion. Each burner grate is fixed to the frame with pin holes for coaxial alignment of the burner grate with the burner head, in which the burner grate contains a round metal element with a plurality of metal static strips supporting the lower surface of the body to be heated. Each heat deflector is coaxial with the burner head and sits on a frame, in which the heat deflector promotes optimum introduction of secondary combustion air and reduces the annular gap between the heat deflector's inner circumference and the burner head's outer circumference to minimize heat loss, in which the heat deflector has a curved orientation to reduce heat transfer down and generates vortices to increase heat transfer down the case. The legs are located under the frame of the domestic cooker, in which each leg has a predetermined height to maintain a gap between the top surface of the table and the bottom surface of the air inlet frame.

EFFECT: invention allows to increase thermal efficiency.
