Definitions

  • the present invention relates to an oven that enables the food placed therein to be cooked more homogeneously and effectively.
  • One or more heaters are provided in ovens wherein the cooking process is performed by means of convection, and the food is cooked by the heat transfer created between the air heated by the said heater and the foods to be cooked.
  • the temperature of the cooking chamber is relatively higher near the heater and is lower in the distant parts. Therefore, the cooking process cannot be performed homogeneously.
  • a fan is disposed on the rear wall of the cooking chamber, providing the air heated by the heater to be distributed in the cooking chamber homogeneously by the actuation of the fan and to increase the heat transfer between the hot air to the food to be cooked.
  • a rear wall is utilized that divides the cooking chamber volume into two such that a compartment containing the fan and the heater is formed for directing the air activated by the fan and maintain a homogeneous air distribution in the cooking chamber.
  • Patent No US4357522 guiding means are provided on the rear wall for directing the air activated by the fan.
  • the aim of the present invention is the realization of an oven wherein the foods (to be cooked) are cooked effectively and evenly by maintaining a homogeneous air circulation in the cooking chamber.
  • the oven realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a depression containing suction holes thereon, the base of which projects out of the uppermost and lowermost positions wherein the trays can be placed, including the portion of the rear wall corresponding to the area swept by the fan.
  • the base of the depression is shaped elliptically.
  • the ellipse shape is advantageous since configuration of the depression can be thin, long and with curved sides, with a width that does not project to the side portions of the rear wall containing the blowing holes thereon. By means of the curved sides, a more effective air flow can be maintained towards the suction holes.
  • a fan is disposed at the level of both focuses of the ellipse and the suction holes on the depression are positioned to be opposite the fans.
  • channels are formed such that the air blown from the blowing holes on the rear wall are directed towards the suction holes.
  • the channels are preferably arranged symmetrically around the depression and configured to be curvedly compatible to the rotational direction of the fan.
  • the air blown from the blowing holes after maintaining heat transfer with the food to be cooked, proceeds from the channels by suction effect of the fan, reaching the depression and the suction holes from there.
  • Figure 3 - is the front view of the rear wall and the trays.
  • Figure 4 - is the perspective view of the rear wall and the trays.
  • Figure 5 - is the detailed perspective view of the rear wall.
  • Figure 6 - is the perspective view of the depression in another embodiment of the present invention.
  • the oven (1) comprises
  • the rear wall (4) is a plate configured to comprise suction holes (7) for aspirating air from the cooking chamber (3) and blowing holes (8), for the air activated by the fan (6) to be blown into the cooking chamber (3) ( Figure 2).
  • the rear wall (4) furthermore comprises a depression (9) sized to also include the portion corresponding to the sweeping area of the fan (6) and extending to at least above the uppermost and below the lowermost positions wherein the tray (T) can be placed, having suction holes (7) thereon ( Figure 2 and Figure 3).
  • the base of the depression (9) is shaped elliptically.
  • the flow is more effectively directed towards the suction holes (7) by means of the ellipse shaped curved configuration of the depression (9) base.
  • a fan (6) each is disposed at the level of the focuses of the ellipse shaped base of the depression (9) and the suction holes (7) are distributed on the depression (9) to correspond to the areas swept by both of the fans (6).
  • the air heated by the heater (5) is activated by the fan (6) and delivered to the front side of the cooking chamber (3) from the blowing holes (8).
  • the air contacting with the food to be baked and contributing to the cooking process is aspirated later on from the suction holes (7) to behind the rear wall (4).
  • the air particularly in the upper and lower regions of the cooking chamber (3) can be aspirated more effectively due to the depression (9) extending to those regions also.
  • the rear wall (4) comprises channels (10) at the sides of the blowing holes (8) that direct the air towards the suction holes (7).
  • the channels (10) are preferably positioned symmetrically around the depression (9) and have a curved configuration compatible to the rotational direction of the fan (6).

Abstract

La présente invention porte sur un four (1) qui comprend un creux (9) formé sur la paroi arrière (4) et présentant des trous d'aspiration (7) sur celle-ci, dimensionnés pour comprendre la partie correspondant à la zone de balayage du ventilateur (6) et s'étendant au moins jusqu'au-dessus de la position la plus élevée et au-dessous de la position la plus basse, le plateau (T) pouvant être placé pour cuire l'aliment de façon efficace et uniforme par le maintien d'une circulation homogène d'air dans la chambre de cuisson (3).
