Oven or Grill Burner

Abstract

The invention relates to an oven or grill burner composed of a flat body delimiting an inner chamber and having fastening protrusions, wherein fastening members are composed of at least a tab made of one piece with a flat body wall or walls. In one embodiment, the burner of the present invention includes mountings for fastening a thermocouple and / or igniter and / or a venturi tube that supplies an air and gas mixture, all included as integral members of the burner. The burner of the present invention is shaped such to increase the even distribution of the air / gas mixture to outlet holes and further includes such constructive characteristics that provide for a reduction in the thickness of the metal sheet used for making the burner without compromising burner strength.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an oven or grill burner. More particularly, the present invention relates to a burner that can be used either for an oven or a grill and that includes a flat box body delimiting an inner chamber and fastening protrusions.BACKGROUND OF THE INVENTION[0002]Burners are known that belong to the so called flat type. These burners can be composed of two half shells and have the advantageous characteristic of including an integrated pilot burner, which is made of one piece by bending the peripheral edges when the two half shells are joined together. Therefore, any drawback associated to proper positioning is obviated. The main gas outlet holes and the holes for supplying gas to the pilot burner are obtained by perforation of one of the two half shells. In another type of flat burner, each half shell has a corrugated edge opposite to that of its respective opposite half shell and the gas / air mixture outlet holes are generated by co...

AI Technical Summary

Benefits of technology

[0004]It is an aim of the present invention to provide a flat burner that can be used either for an oven or a grill and that has improvements over the prior art intended to rationalize and make its manufacturing faster by [[,]] limiting and making assembly steps easier, above all by limiting operations for fastening additional members like connections fastening the burner, thermocouples and igniters, and also by limiting operations for proper positioning.

[0006]It is also an aim of the present invention to improve the distribution of gas and air mixture inside the burner, in order to obtain a more even distribution of the flame.

[0007]It is a further aim of the present invention to limit material waste and to allow the use of thinner metal sheets, which are also easier to handle, without reducing the strength of the burner.

[0017]These contacting areas also form spacing members stiffening larger walls of the burner, limiting the thickness of the metal sheet without compromising stability and strength of the burner.

Problems solved by technology

Therefore, any drawback associated to proper positioning is obviated.

Although in this second type the perforation step is avoided, the holes still have a rather large size, which is further subjected to changes in the heating step, and sealing problems may occur between the two half shells.

Also, unlike tubular burners, flat burners may have inner walls for modulating gas distribution among the various holes, and the lack of these walls might cause unevenness problems, especially at low flame levels.
