Definitions

  • the present invention relates to a cooking appliance with a cooking chamber and a fan chamber with rear wall, wherein in the fan chamber, a fan is arranged, which is surrounded by at least one heater, and fresh air to the fan chamber via a feed line in the rear wall can be fed.
  • Cooking appliances are well known in the art. They usually include a cooking chamber and a fan room, which are usually separated by a baffle. Within the fan chamber, a fan wheel is arranged, which sucks air from the cooking chamber and redirects radially to the surrounding walls, so as to generate an air flow within the cooking appliance. Concentric around the impeller, a heater is often arranged so that recirculated air is also passed through this heater to heat the recirculated air.
  • circulated air contains solid and / or liquid particles, in particular fat. This solid and / or liquid particles of the circulation thus also passed through the heater where they can be deposited and burned by the heater, which can lead to a reduction in food quality and an odor nuisance. This problem arises in particular when the air is circulated permanently within the cooking appliance, in which case the solid and / or liquid particles are constantly held in the gas volume by the circulating air flow.
  • DE-U 90 05 858 discloses a device comprising an impingement surface on which a gas stream prevailing in the gas volume impinges, whereby the solids and / or or at least partially deposit liquid particles on impact and run to a first discharge area.
  • the patent GB-A 2373714 shows an oven with a fan wheel, which has a cutting disc.
  • the supplied fresh air practically ruptures the solids and / or liquid particles to be separated off on the rear wall, and since the supplied fresh air can flow unhindered through the heating device, the solid and / or liquid particles are deposited on the heating device, which is associated with the above-described disadvantages is.
  • the present invention is therefore an object of the invention to provide a generic cooking appliance, which overcomes the disadvantages of the prior art, in particular prevents fresh air, which is introduced into a cooking appliance, in the cooking appliance circulated air, which contains solid and / or liquid particles , can move freely to the heater.
  • the object of the invention is achieved by a disc between the rear wall and the fan with a diameter such that the heater is covered by the disc substantially completely opposite the rear wall.
  • a preferred Ausfixhrungsform of the invention provides that the disc is designed as a carrier disk for the fan and fixedly connected to the fan.
  • the disc has at least one opening in the region of the fan wheel.
  • a further embodiment of the invention provides that the fan wheel is concentrically surrounded on its side facing the disk by a ring extending away from the fan wheel.
  • the ring is inclined in the direction of the disc.
  • the fan is a rotor, a radial fan or the like.
  • the heating device comprises heating coils.
  • the invention is based on the surprising finding that the disadvantages of the prior art are overcome by the arrangement of a disc between the rear wall and fan, when the disc further has a diameter, so that the heater surrounding the fan essentially completely covered with respect to the rear wall is.
  • Fresh air flows in the cooking appliance according to the invention through the feed line into the space between the rear wall and the pane, the fresh air is led laterally outwards and can only emerge from the space between the rear wall and the pane when the fresh air can no longer strike the heating device directly.
  • the supplied fresh air can not entrain solids and / or liquid particles to be deposited on the rear wall or the disc.
  • the cooking appliance according to the invention thus ensures that significantly less solid and / or liquid particles, in particular Grease, deposited on the heater where they would be burned. As a result, the food quality increases significantly and odor nuisance is drastically reduced.
  • a particularly advantageous solution to the problems of the prior art is achieved if, in addition to the use of a disc and a fan surrounding the surrounding inclined ring is provided, which ensures that the solid and / or liquid particles to the rear of the disc or the Rear wall are deposited.
  • FIG. 1 shows a cross-sectional view of a detail of a cooking appliance according to the invention.
  • the figure shows a section of a fan room of a cooking appliance according to the invention.
  • a fan wheel 1 is arranged, which can be driven by a motor, not shown, which is arranged on the outside of a rear wall 2.
  • a shaft 3 of the motor is indicated, wherein the shaft 3 of the motor is guided through the rear wall 2 in the interior of the cooking appliance.
  • a heating device is provided, which is preferably constructed of heating coils 4.
  • the fan wheel 1 further comprises a ring 5 which concentrically surrounds the fan wheel and which is inclined in the direction of the rear wall 2.
  • a space 7 is formed, can be introduced via the fresh air radially into the fan room and the cooking appliance.
  • a disc 8 according to the invention is further arranged, whose diameter is designed so that the heater 4 is covered by the disc 8 substantially completely opposite the rear wall 2.
  • This disc 8 can either be firmly connected to the rear wall 2 or in the form of a carrier disk firmly connected to the fan 1.
  • the disk 8 preferably has at least one opening in the area of the fan wheel 1.
  • the advantages achieved with the cooking appliance according to the invention are as follows: During a cooking process, fresh air is introduced via the feed line 6 into the space 7 between the rear wall 2 and the pane 8. This fresh air passes through the prevailing within the cooking flow to the sides of the room 7 and can only enter the fan room when the fresh air can not get directly to the heater 4. Since the disk 2 substantially completely covers the heating device 4 with respect to the rear wall 2, the supplied fresh air can not absorb solids and / or liquid particles from the circulated air within the cooking appliance and forward them to the heating device 4.
