Definitions

  • the invention relates to an oven according to the preamble of claim 1.
  • a fan wheel of a convection fan is arranged in a blower chamber formed by a cover wall on the one hand and by the rear wall of the cooking space on the other hand, and on both sides of the cover wall near the side walls of the cooking space there are elongated, vertical Blow-out slots, to which substantially narrower, further blow-out slots are assigned immediately adjacent.
  • edges or bends projecting into the flow path are provided on the first-mentioned blowout slots as well as on special air guiding elements in the interior of the blower chamber. The turbulence of the outflowing air is further increased by the second-mentioned narrow slots.
  • the invention is based on the object, in a baking oven of the type mentioned in the preamble of claim 1, the flow of the air blown out through the exhaust slots in relation to the food to be found in the cooking space, in particular in the central region of the cooking space, without additional, expensive To improve air control elements.
  • the design should be suitable for cooking using microwave energy.
  • blow-out slots Due to the configuration of the blow-out slots according to the invention, the possibility is given to influence the flow conditions at the opposite blow-out slots depending on the direction of rotation of the circulating air fan by appropriate dimensioning and number of webs and slot sections. In this way, in particular, the air flow can be made more uniform and the air flow improved, particularly in the central region of the oven. This eliminates the need for additional air baffles or the like inside the blower chamber.
  • the special design of the blow-out slots achieves microwave tightness of the blower chamber, the successive slot sections separated by webs being able to be relatively large if the blow-out slots face the adjacent cooking space walls, i.e. are located in the side area of the cover wall.
  • a cooking space 1 is delimited by a cuboid oven muffle 2, which can be closed by an oven door (not shown).
  • a radiant heater 4 is located directly below the upper cooking chamber wall 3.
  • a heating element 6 forming the bottom heat of the oven is arranged below the lower cooking chamber wall 5.
  • rib-like supports 9 are fastened, for example, at two different heights, on which, for example, two rust-like or pan-like food supports 10 or baking trays with a supporting frame can be mounted.
  • a trough-like cover wall 12 Located in front of the rear cooking chamber wall 11 is a trough-like cover wall 12, which partially limits the cooking chamber 1 towards the rear and forms a blower chamber 13 between the rear cooking chamber wall and this cover wall 12.
  • the cover wall 12 consists of an essentially flat trough base 14, from substantially rectangular side and flat trough edges, for example 15 and 16 (FIGS. 2, 3), and from trough flanges, for example 17, 18, which are connected and run parallel to the trough base 14 and are flat or rest flush against the rear wall 11 of the cooking space.
  • the cover wall 12 essentially covers the entire rear cooking chamber wall 11.
  • blow-out slots 21 and 22 which are arranged at different heights depending on the direction of rotation of the fan wheel 20, such that the blow-out slot 21 is higher than the blow-out slot due to the downward-directed partial air flow 22 for the upward air control component (Fig. 1).
  • the blow-out slots 21 and 22 consist of successive slot sections 21a and 22a which are separated from one another by narrow webs 21b and 22b.
  • the webs of the metallic cover wall 12 are metallically connected to the opposite slot longitudinal edges of the blow-out slots 21, 22 and act in the microwave case as short-circuit bars, which prevent microwave leakage from the oven chamber 1 into the blower chamber 13.
  • These blow-out slots 21, 22 lie opposite the adjacent side cooking chamber walls 7 and 8, so that the essentially laminar air flow emerging from the blow-out slots hits these side cooking chamber walls directly and is reflected and swirled into the interior of the cooking chamber 1, as by flow arrows illustrated in Fig. 1.
  • the blow-out slots 21, 22 or the number and size of the slot sections and the webs can be varied.
  • blow-out slots at other locations on the cover wall or, in addition to the blow-out slots shown in the exemplary embodiment, further blow-out slots to provide, for example, a flow in the direction of the upper radiator or a temperature sensor.
