Abstract
A holder assembly for a burner of a gas cooking appliance. According to one embodiment, the assembly includes a gas conduit, an injector partially housed at a first end of the gas conduit. The assembly further includes a burner base and an injector base arranged below the burner base, the injector base having a through hole in which portion of the first end of the gas conduit is arranged such that the injector is oriented towards the burner base. The through hole of the injector base has at least one non-circular coupling segment, and the gas conduit has a plastically deformed intermediate segment covering the coupling segment.
Claims20
A holder assembly for a burner of a gas cooking appliance, the holder assembly comprising:
- a holder including a burner base and an injector base arranged below the burner base, the injector base including a through hole, the through hole including a coupling segment having a non-circular cross-section delimited by an inner wall;
- a gas conduit having a first end, the first end including an intermediate segment that is plastically deformed inside the coupling segment such that an outer surface of the intermediate segment abuts the inner wall of the coupling segment, the non-circular cross-section of the coupling segment preventing the first end of the gas conduit from rotating inside the coupling segment;
- and
- an injector partially housed at the first end of the gas conduit, the injector having a central through opening with a gas outlet facing in a direction of the burner base.
A method of making a holder assembly for a gas burner of a cooking appliance, the method comprising:
- obtaining a holder that includes a burner base and an injector base arranged below the burner base, the injector base including a through hole, the through hole including a coupling segment having a non-circular cross-section delimited by an inner wall;
- inserting a first end of a gas conduit into the through hole of the injector base, the first end of the gas conduit having an outer diameter less than an inner diameter of the through hole;
- plastically deforming an intermediate segment of the gas conduit inside the coupling segment such that an outer surface of the intermediate segment abuts the inner wall of the coupling segment, the non-circular cross-section of the segment preventing the first end of the gas conduit from rotating inside the coupling segment;
- and
- attaching an end of an injector to the first end of the gas conduit in an airtight manner, the injector having a central through opening with a gas outlet, the injector being attached to the first end of the gas conduit so that the gas outlet faces in a direction of the burner base.
