1. A cooking appliance, comprising:
- several cooking devices distributed over a cooking hob, the cooking devices including, at the front of the appliance, two front cooking devices separated by a space and at least one of which is a gas burner including in particular a burner head, and having flame outlet orifices distributed around a peripheral line of a flame distributor ring forming part of the burner head, said orifices constituting the outside end of fuel mixture delivery ducts formed in the ring, said appliance further having;
in orthogonal projection in a mean plane perpendicular to the axis of said at least one of said front burners, the longitudinal directions of the ducts at their intersection with the peripheral line all exhibit an inclination to the same side with respect to this line such that the burner is a burner with flames spiralling about the axis of the burner,the inclination is such that in each said burner generating the spiralling flames, the flames adjacent to the said space separating said two front burners are inclined towards the rear of the appliance such that when at least said two front burners are ignited, the flames are reinforced by convection currents passing between said front burners in the same direction as the flames.

Abstract
The invention concerns a cooking appliance comprising devices for cooking of which at least one burner with spiralling flames. The ducts for delivering the fuel mix towards the external part of the burner with spiralling flames are inclined with respect to a peripheral line on which the flame outlets are distributed. The invention is useful for high-powered gas burners for cooking food.

20. A gas burner for a cooking appliance comprising several cooking devices distributed over a cooking hob, the cooking devices including, at the front of the appliance, two front cooking devices separated by a space and at least one of which is a gas burner including in particular a burner head, and having flame outlet orifices distributed around a peripheral line of a flame distributor ring forming part of the burner head, said orifices constituting the outside end of fuel mixture delivery ducts formed in the ring, said appliance further having:
-
in orthogonal projection in a mean plane perpendicular to the axis of the burner, the longitudinal directions of the ducts, at their intersection with the peripheral line, all exhibit an inclination to the same side with respect to this line, such that the burner is a burner with flames spiralling about the axis of the burner; the inclination being such that the flames adjacent to the said space are inclined toward the rear of the appliance; the angle of said inclination being less than 40°
; andeach block of material separating two consecutive ducts being projected, in a mean plane perpendicular to the axis of the burner, substantially as a quadrilateral having two opposite acute angles and two obtuse angles, each acute angle being adjacent to an obtuse angle and said acute angles being rounded.

21. A method for mounting a gas burner with spiralling flames on a cooking hob designed for at least two cooking devices at the front and for at least one at the rear, comprising placing the burner with spiralling flames at the front of the cooking hob and on a side such that the flames adjacent to the other cooking device located at the front of the cooking hob are inclined towards the rear of the cooking hob, and such that a recess for an accessory of the burner, which causes a local flame attenuation in service, is located on the side facing said other cooking device.
