Definitions

  • a convection cooking appliance according to the preamble of protection claim 1 is already known, in which the heat-generating parts are arranged in the hood, i.e. above and opposite the pan.
  • this has the disadvantage that the hood heats up very much and there is a risk of burns from the outside.
  • Another disadvantage is that there is an unattractive sight because the hood is relatively high and is generally opaque in the area where the heat-generating parts are accommodated.
  • Another disadvantage is that when the hood is removed it has to be parked somewhere, and after this hood heats up extremely during operation, there is a risk of burns and damage at the points where the hood is lowered.
  • the innovation is therefore based on the object of further developing a convection oven of the type mentioned at the outset in such a way that a risk of burns on the hood of an appliance in operation is avoided, that the appliance is smaller overall and can be used more reliably.
  • the innovation is characterized by the technical teaching of claim 1.
  • An essential feature of the innovation is that the drive parts and the heating parts are now arranged in the lower part of the device below the pan and that the hood itself is free of internals.
  • the hood can now be designed as a transparent part, so that the entire cooking and grilling process can be observed continuously.
  • the hood will heat up only slightly during operation, because only a heated air stream is pumped through the hood, which is generated by the hot air-producing parts arranged below the pan. So you can touch the hood from the outside during operation of the device because the hood is no longer heated and you can also remove the hood and place it on surfaces without the risk of damaging such surfaces.
  • the air-generating parts are arranged on the lower part of the device and the heating air is circulated in a direct circuit without turbulence in the hood, so that a blow-out opening is provided on one side wall of the hood in a housing surface is while the suction port is arranged in the vicinity of the opposite side wall of the hood in the opposite housing surface. In this way there is a laminar air flow in the hood without generating turbulence.
  • Another important advantage of the invention is that the heat-generating parts are now arranged directly below the pan and are even in conductive contact with the pan, so that a favorable heat transfer to the pan takes place.
  • FIG. 1 cross section through a convection cooking appliance according to the innovation
  • FIG. 1 Detail section according to II in Figure 1 through one side of the cooking device.
  • the cooking device here as a convection cooking device, is shown in a cross section, it being apparent that a motor 14 drives a fan 15 which is located in a container 19.
  • the air flow is heated by a heater 13 and then guided into the hood 1 via the fan 15 via an exhaust slot 21 and fed back to the fan 15 from the hood 2 via a suction opening.
  • the fan 15 is designed as a radial fan and the air flow is guided over an intermediate plate 20, the air flow entering the hood 1 and sweeping over the pan 22 and being discharged via the suction opening 2 and being fed to the food to be cooked via the outlet opening 21.
  • the cooking temperature and the cooking time are set via a controller 18 and a timer 16.
  • the food is either fed directly to the pan 22 or placed there on a rack.
  • the device switches off via a switch 7.
  • the convection oven is shown in its structure, wherein a hood 1 is provided which is seated on a housing 6. Furthermore, a pan 22 is provided within the cooking device, a suction opening 2 to the fan 15 and a blow-out opening 21 being formed on the side.
  • a handle 4 is formed on the hood 1, a switching lug 3 actuating a switching plunger 5 of a switch 7 which is fastened to the housing 6.
  • An insulation sheet 11 with an insulation disk 10 is provided above the bottom 8 of the cooking device for insulation with respect to the heater 13.
  • a drain pipe 9 is formed down towards the bottom 8 of the device.
  • Working fan is referred to, and a cooling fan 12 are provided and a heater 13, these parts being provided in the lower part of the cooking device.
  • the air cycle is through the unit of working fan 15, container 19, intermediate plate 20 and air baffle 28 and the pan 22 and the hood 1 are formed.
  • the active parts such as the motor 14, the fan 15 and the cooling fan 12, are fastened to the base 8 of the cooking device and form a unit there with the heater 13.
  • an air flow is formed starting from the cooling fan 12, the cooling air being passed on via air slots 25, 26 on the outside of the cooking device in the suction area of air slots 22.
  • a suction opening 2 and a blow-out opening 21 are formed, which are arranged in the region of a circumferential air guide bevel 23.
  • the air guide bevel 23 has an angle 24 of preferably 60 ° + 15 °.
  • the pan 22 sits on a peripheral edge.
  • the container edge 29 is located below the housing edge 30.
  • the housing edge 30 itself has a run-off slope 31 of preferably 3 °.

Abstract

L'invention concerne un appareil de cuisson à circulation d'air permettant de faire cuire, de faire rôtir, de faire cuire à l'étouffée et de griller des aliments. Cet appareil comprend une partie inférieure comportant une poêle (22), et un capot (1). Un ventilateur actionné par un moteur (14) et constituant une partie active, ainsi qu'un dispositif de chauffage (13), permettent à un courant d'air chauffé de circuler. Le courant d'air arrive depuis la partie inférieure de l'appareil de cuisson, circule le long de la poêle (22) et à travers le capot (1). La partie active (moteur (14) et ventilateur), de même que le chauffage (13) et un ventilateur de refroidissement, se trouvent dans la partie inférieure de l'appareil de cuisson.
