Definitions

  • a known oven ( DE 103 13 916 A1 ) is provided at the rear end of the cooking chamber separated by a baffle a blower chamber in which a fan is located, which sucks the process air from the cooking chamber through an upstream suction and through this through air outlet openings - in different quadrants of the cooking - again in the oven Direction of the front oven door and from there reflective transported around the stored in several levels on Gargutarrin food to the intake of the baffle plate.
  • air guide in the upper and lower quadrant air outlet openings are arranged, behind which are air guide elements for the purpose of alignment of the air outlet opening through the air outlet opening in the direction of the cooking chamber and the cooking chamber floor exiting air flow .
  • air guide elements for the purpose of alignment of the air outlet opening through the air outlet opening in the direction of the cooking chamber and the cooking chamber floor exiting air flow .
  • the present invention has for its object to improve a hot air or convection oven so that with simple constructive measures within the cooking chamber, a flow of heated process air in all areas of the room, i. also in fluidically problematic, very far above and / or below in the cooking chamber food support levels and thus a uniform heat treatment of the food is guaranteed.
  • a hot air or convection oven with a front oven door having cooking chamber with lying in several levels food supports, with a cooking chamber separated by a baffle blower with therein blower, which air baffle a central intake for the fan and has air outlet openings and edge-side flanks, which are inclined to the rear cooking chamber wall at an angle relative to this substantially planar and vertical cooking chamber wall and at least in the upper flank in the direction of the adjacent upper cooking chamber wall facing air outlet openings.
  • the inclined flanks and the air outlet openings therein function functionally as air guiding elements, so that in this respect can be dispensed with additional air guide elements such as reflection surfaces or the like, whereby the furnace construction can be made very simple and cost-saving.
  • the invention enables optimal use of the entire cooking chamber volume for the cooking treatment of food.
  • the air-guiding plate has air outlet openings in all peripheral flanks. It has proven to be advantageous if at least the upper edge of the baffle plate has an angle of inclination of 30 ° to 60 ° relative to the plane of the rear cooking chamber wall. It is assumed that the central, vertical surface part of the air guide plate extends parallel to said cooking chamber wall. This gives a flat upper and possibly also lower flow profile, which extends through the cooking chamber after reflection substantially arcuate.
  • the lateral flanks of the baffle plate have an angle of inclination of 60 ° to 80 ° relative to the plane of the rear cooking chamber wall.
  • air outlet openings can be arranged very far laterally outward, for example, outside the food support, which on the one hand, the best possible use of the existing cooking space volume is made possible and
  • the flow conditions are made largely independent of the geometry of the lateral cooking chamber walls.
  • the in Fig. 1 illustrated hot air oven has the cuboid cooking chamber 1 forming cooking chamber namely a bottom wall 2, an upper ceiling wall 3, a rear cooking chamber 4, side cooking chamber walls 5 and a front wall in the form of a hinged axis 6 in the direction of arrow pivoting oven door 7.
  • Gargutla levels E1 to E4 equipped with suitable management facilities for example large-scale food support for intended for heat treatment, for example, to be cooked food.
  • baffle 8 ventilated separated from a fan 9 with this surrounding electric ring heater 10 containing blower chamber 11.
  • the baffle 8 has at the top and bottom of the rear cooking chamber 4 out angled flanks 12, 13 with where the air guide plate 8 can be attached to the rear cooking chamber wall 4.
  • On the lateral boundaries of the substantially rectangular air guide plate are also integrally formed side flanks 23, 24, which are arranged inclined in the direction of the lateral cooking chamber 5 side.
  • the air guide plate 8 further has a central intake opening 14 in front of the blower 9 for the suction of the cooking chamber 1 to be flowed through process air according to the arrow and in the vertical region of the air baffle 8 upper and lower, illustrated by arrows air outlet openings 15, through which hot air is substantially rectified, ie flows in the outflow direction without intimate contact with the lateral cooking chamber walls 5 and the food in the direction of the oven door 7 and there reflected in contact with the food to the cooking chamber 1 to flow through to the intake port 14.
  • a rod-shaped temperature sensor 16 of a temperature control device 17 in the upper edge 12 is assigned its own air outlet opening 18 through which an air flow directly from the fan chamber 11 to the temperature sensor 16 passes and causes a very immediate temperature control.
  • the lateral flanks 23 and 24 of the baffle 8 with an angle of inclination b of 60 ° to 80 ° are arranged steeply with respect to the plane of the rear cooking chamber wall 4 and thus the vertical central plate surface of the air baffle 8. Also in these flanks and far outside in the said, the suction opening 14 having plate surface air outlet openings 15 may be provided, for example.
