AI Technical Summary

Problems solved by technology

This leads to a large difference in baking results between the food product present in the central area of ​​the food preparation chamber and the food product present along the inner walls
Although the cyclonic air flow pattern requires more kinetic energy, it leads to worse and less consistent results

Embodiment Construction

[0022] refer to figure 1 , the device comprises an outer housing 1, which may be made of plastic material. Within said housing 1 , a double-walled food preparation chamber 2 is defined surrounded by an inner wall 3 and an outer wall 4 . In the bottom of the inner wall, the inner wall 3 is provided with an air-permeable bottom portion 5 . On top of the inner wall, the inner wall is provided with outlet openings 6 for air.

[0023] Above the discharge opening 6 is arranged a fan 7 driven by an electric motor 8 (the speed of which may be controllable). By the low pressure induced on one side of said fan 7 , air is sucked from the food preparation chamber 2 through the outlet opening 6 and delivered at high pressure in the channel 9 defined between the inner wall 3 and the outer wall 4 . Air is thus forced through said channels 9 , towards and through the inner wall 3 permeable to the bottom part 5 to reach the food preparation chamber 2 again.

[0024] It is worth noting that...

Abstract

An apparatus for preparing food comprises a food preparation chamber with an air-permeable bottom wall and an upper air discharge opening, a fan for moving hot air succesively through the bottom wall, the food preparation chamber and the discharge opening, an air channel for returning the air from the discharge opening towards the bottom wall separate from the food preparation chamber, a heat radiator positioned in the upper part of the food preparation chamber and an air guide below the food preparation chamber and on top of a bottom part for directing the air flow essentially upwards into food present in the food preparation chamber. Said air guide comprises at least one air guide rib arranged along a curved line extending substantially towards a central region of said bottom part, wherein said air guide rib is provided with a concave side which, as seen in a vertical section through said air guide rib, along at least part of its extension along said curved line includes an angle with the bottom part smaller than 90°.

Description

technical field [0001] The present invention relates to an apparatus for preparing food comprising: a food preparation chamber having an air permeable bottom wall and an upper air discharge opening; a fan for continuously moving hot air through Bottom wall, food preparation chamber and discharge opening; air guide separate from the food preparation chamber for returning air from the discharge opening towards the bottom wall; heat radiation device arranged in the food preparation chamber in the upper part; and air guiding means below the food preparation chamber and on top of the bottom for introducing air flow substantially upwards into the food product present in the food preparation chamber. Background technique [0002] This type of equipment provides a method for the preparation of food in which the food is simultaneously heated by convection (by air flow) from below and by radiation (by heat radiation means) from above. The air heated by the heat radiation means circul...
