Abstract
An over or grill burner includes a hollow body with a supplying port receiving a gaseous fuel mixture and outlet holes emitting the gaseous fuel mixture, and a conveying duct conveying the gaseous fuel mixture toward the hollow body, which has a delivering port and a supplying/mixing port with a first aperture for a fuel gas and a second aperture for a gaseous combusting product, and a reflector conveying a flame produced by combustion of the fuel mixture from the outlet holes. The supplying port of the hollow body and the delivering port of the conveying duct have a substantially circular cross-section and are connected to each other in a freely rotatable manner.
Claims20
An oven or grill burner comprising:
- a hollow box-shaped body having a supplying port receiving a gaseous fuel mixture and outlet holes emitting said gaseous fuel mixture;
- a conveying duct conveying the gaseous fuel mixture toward the box-shaped body, the box-shaped body having a delivering port and a supplying/mixing port provided with a first aperture for a fuel gas and a second aperture for a gaseous comburent;
- and
- a reflector conveying a flame produced, in use, by combustion of the fuel mixture from the outlet holes,
- wherein the supplying port of the box-shaped body and the delivering port of the conveying duct have a substantially circular cross-section and are connected to each other in a freely rotatable manner.
A process for manufacturing an oven or grill burner in combination with a flame arc forming head made separately and obtained by not simply bending half shells of the burner, comprising:
- forming an upper half shell and a lower half-shell by cutting a metal sheet blank, by bending, drawing and trimming contours and making outlet holes for a gas air mixture in the upper half-shell;
- crimping the two half shells for creating the burner body contemporaneously forming a pilot burner such to form a tubular burner body truncated at both the ends;
- locking an end closing and/or flame arc forming head member at the truncated end of the burner body by clutching and mechanical compression deformation;
- and
- locking a rectilinear or curved joint at the opposite truncated end of the burner body, by clutching and mechanical compression deformation.
