Definitions

  • the present invention relates to a cooking appliance with a cooking space and a fan space with a rear wall, wherein a fan wheel is arranged in the fan space, which is surrounded by at least one heating device, and fresh air can be supplied to the fan space via a feed line in the rear wall.
  • Cooking devices are generally known from the prior art. They usually include a cooking space and a fan space, which are usually separated from one another by an air baffle.
  • a fan wheel is arranged inside the fan chamber, which draws air from the cooking chamber and redirects it radially to the surrounding walls, in order to generate an air flow within the cooking device.
  • a heating device is often arranged concentrically around the fan wheel, so that circulated air is also passed through this heating device in order to heat the circulated air.
  • Air circulated within the cooking device during a cooking process contains solid and / or liquid particles, in particular fat. These solid and / or liquid particles of the circulation are thus also passed through the heating device, where they can be separated and burned by the heating device, which can lead to a reduction in the quality of the food and to an unpleasant smell.
  • DE-U 90 05 858 discloses a device for separating solid and / or liquid particles from a gas stream within a cooking device, which device comprises an impact surface onto which a gas stream prevailing in the gas volume impinges, the solid and / or at least partially separate liquid particles on impact and run to a first discharge area.
  • the devices known from the prior art do not take into account the fact that fresh air can or must also be supplied to a cooking appliance, this supply generally taking place via a supply line in the rear wall of the fan space.
  • the fresh air then enters a space between the rear wall and the fan wheel and flows to the side outlets surrounding this space in order to be absorbed into the circulated air flow within the cooking space. It can happen that the fresh air supplied exits the space between the rear wall and fan wheel, the solid and / or liquid particles that are to be separated on the rear wall, swirled again and can be separated on the heating device.
  • the fresh air supplied practically entrains the solid and / or liquid particles to be separated on the rear wall, and since the fresh air supplied can flow unhindered through the heating device, the solid and / or liquid particles are separated on the heating device, which has the disadvantages described above is.
  • the present invention is therefore based on the object of providing a generic cooking appliance which overcomes the disadvantages of the prior art, in particular prevents fresh air which is introduced into a cooking appliance from circulating air in the cooking appliance which contains solid and / or liquid particles , can freely steer onto the heating device.
  • the object of the invention is achieved by a disk between the rear wall and the fan wheel with a diameter such that the heating device is essentially completely covered by the disk with respect to the rear wall.
  • a preferred embodiment of the invention provides that the disk is designed as a carrier disk for the fan council and is firmly connected to the fan wheel.
  • the disk has at least one opening in the area of the fan wheel.
  • Another 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 towards the disc.
  • the fan wheel 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 arrangement of a disk between the rear wall and the fan wheel overcomes the disadvantages of the prior art if the disk also has a diameter, so that the heating device surrounding the fan wheel is essentially completely covered with respect to the rear wall is. If fresh air flows through the supply line into the space between the rear wall and the pane in the cooking device according to the invention, the fresh air is guided laterally outwards and can only emerge from the space between the rear wall and the pane when the fresh air can no longer directly hit the heating device. This means that the fresh air supplied cannot entrain solid and / or liquid particles that are to be separated on the rear wall or the pane.
  • the cooking device according to the invention thus ensures that significantly fewer solid and / or liquid particles, in particular Fat to be deposited on the heater where it would be burned. This significantly increases the quality of the food and drastically reduces the smell.
  • FIG. 1 shows a cross-sectional view of a section of a cooking device according to the invention.
  • the figure shows a section of a fan space of a cooking device according to the invention.
  • a fan wheel 1 is arranged inside the fan space and can be driven by a motor, not shown, which is arranged on the outside of a rear wall 2. In the figure, only the position of a shaft 3 of the motor is indicated, the shaft 3 of the motor being guided through the rear wall 2 into the interior of the cooking device. If the fan wheel 1 is driven by the motor, an essentially radially outward flow of the air in the cooking device is generated.
  • a heating device is provided concentrically around the fan wheel 1, which is preferably constructed from heating coils 4.
  • the fan wheel 1 in the embodiment shown in the figure further comprises a ring 5 concentrically surrounding the fan wheel, which is inclined in the direction of the rear wall 2.
  • a space 7 is formed, via which fresh air can be introduced radially into the fan space or the cooking device.
  • a disc 8 is further arranged according to the invention, the diameter of which is designed such that the heating device 4 is covered by the disc 8 substantially completely with respect to the rear wall 2.
  • This disk 8 can either be fixed to the rear wall 2 or in the form of a carrier disk to the fan wheel 1.
  • the disk 8 preferably has at least one opening in the region of the fan wheel 1.
  • a cooking process is carried out in the cooking device according to the invention, the advantages achieved with the cooking device according to the invention are shown as follows:
  • fresh air is introduced via the supply line 6 into the space 7 between the rear wall 2 and the pane 8.
  • This fresh air reaches the sides of the room 7 through the flow prevailing within the cooking device and can only enter the fan room when the fresh air can no longer reach the heating device 4 directly. Since the pane 2 essentially completely covers the heating device 4 with respect to the rear wall 2, the fresh air supplied cannot absorb solid and / or liquid particles from the circulated air inside the cooking device and pass them on to the heating device 4.
  • the ring 5 also causes the air sucked in by the fan wheel 1 to be conveyed essentially onto the disk 8 or the rear wall 2 (in the direction of the arrow in the figure), so that the solids and / or contained in the circulated air Liquid particles can also not be deposited directly on the heating device 4. This ensures that significantly fewer solid and / or liquid particles are burned on the heating device 4, whereby the food quality can be significantly increased and the odor pollution can be significantly reduced. A swirling of solid and / or liquid particles and fresh air can only take place outside the heating device 4.
