Abstract:
1. Convection oven for cooking food, comprising: a muffle with a generally parallelepipedal interior cavity delimited by a lower floor wall, an upper ceiling wall and four peripheral walls, at least one of the peripheral walls being provided with an access door for entry of food to be cooked into the interior cavity of the muffle and its exit therefrom, convection means, driven in rotation by a motor, disposed in the interior cavity of the muffle in the vicinity of the center of an adjacent peripheral wall with no access door, mounted to rotate about a rotation axis perpendicular to the adjacent peripheral wall, and adapted to cause air to circulate in the interior cavity of the muffle, heating means placed in the flow of air upstream or downstream of the convection means, and adapted to heat the air that is propelled into the muffle by the convection means to cook the food, a cooking volume, reserved in the interior cavity of the muffle to receive food to be cooked, wherein: the convection means comprise a centrifugal convection turbine adapted to aspirate air axially toward the center of the adjacent peripheral wall and to discharge it radially toward the edges of the adjacent peripheral wall, the convection turbine and the heating means are placed in the interior cavity of the muffle in direct communication with the cooking volume with no separating wall opposing the circulation of air between the convection turbine and the cooking volume, with no separating wall opposing the circulation of air between the heating means and the cooking volume, with a mechanical protection grid conformed and interposed between the convection turbine and the cooking volume to prevent the contact of a user's hand with the blades of the rotating convection turbine.
