Definitions
- the invention relates to a cooking appliance with a cooking space, a blower space, an air baffle, a ventilation device, such as in the form of a fan wheel or the like, a heating device and a catalyst, wherein the air baffle at least one inlet and Has outlet opening for air circulation between the cooking space and the blower space, air on the catalytic converter including swaths of fat, odor particles and / or hydrocarbons the catalyst can be finely atomized from the cooking chamber by the ventilation device cleans the air directed at it, releasing energy, from the catalyst cleaned air and / or the energy released during cleaning in the form of heat the ventilation device can be distributed into the cooking space, the catalyst essentially is arranged concentrically around the heater, and the heater substantially is arranged concentrically around the ventilation device.
- a baking or roasting oven with an oven muffle in which a motor-driven impeller is arranged adjacent to the rear wall. Concentric for this purpose there is a heating element in the flow direction and one for the fan wheel conveyed air permeable catalyst arranged. To have a high catalyst effect To achieve, the catalyst is designed like a sponge, its effective Surface is coated with a catalytically active coating.
- a device for separating solid and / or liquid particles from a Gas volume with at least one impact surface is, for example, from DE 42 06 846 C2 known.
- DE 198 24 172 describes a cooking device with an energy storage and energy extraction system discloses that with a measuring and already existing in a conventional cooking device Control system is connected, so that heating power can be reduced on the one hand and on the other hand Waste heat is usable.
- An energy storage device can be used during cooking breaks, as in the case of a Batch operation always occur or are due to the cooking process, and / or in aprioren Cooking phases in which a cooking process requires little or no energy by means of, if necessary additional, heating, controlled by the measuring and control system, according to a priority hierarchy to ensure an undisturbed sequence of a cooking process, or by the Exhaust air or excess steam escaping from the cooking space to be charged, then in hyperior cooking phases, in which the cooking process takes a lot of energy required, more than the heating installed to heat the food can deliver to be able to take from the energy storage.
- EP 0 772 514 B1 describes self-cleaning surfaces which through the artificial implementation of a microscopic surface structure, as used for the Lotus bloom is known in hydrophobic polymers or durable hydrophobic materials are realizable.
- the object of the present invention is the generic cooking appliance to further develop the disadvantages of the prior art, in particular Coarse dirt, grease splashes and / or the like can be caught and does not hit the heater, so that the heater is protected becomes.
- an impact surface which essentially is arranged concentrically around the heating device, the heating device at least is partially arranged in the flow shadow of the impact surface.
- the catalyst in the form of a variety of catalyst elements attached to a catalyst housing.
- An embodiment of the invention is characterized by an air supply line, via the fresh air can be introduced in a controlled manner, in particular to oxidize fats and odor particles and / or to drive hydrocarbons.
- the impact surface in the rear area of the cooking space is arranged in the blow-out direction.
- the impact surface in the form of a separating ring for separating solid and / or liquid particles from a gas volume is trained.
- the heating device in the form of at least one, preferably two, annular radiators is formed.
- an energy storage and / or energy extraction system is also included Catalyst properties proposed.
- the cooking space, the energy storage and / or Energy extraction system, and / or the heating device with a catalyst, at least in some areas equipped and / or coated.
- the catalyst has a surface with a Surface structure in dimensions of up to a maximum of 500 ⁇ m and self-expanding is.
- the catalyst is aluminum oxide and / or Includes platinum.
- the invention is therefore based on the surprising finding that the special Arrangement of the impact surface such that the heating device is at least partially in the flow shadow the impact surface is arranged, this heating device before wear by depositing dirt, grease and / or the like can be spared, since the impact surface such dirt, grease splashes and / or the like.
- the over the impact surface so to speak, pre-cleaned flow aimed at the catalyst to increase whose efficiency will be judged.
- the catalyst can be in the form of individual, separate ones Catalyst elements and / or on the other hand as a (partial) coating of the cooking space and / or an energy storage and / or energy extraction system are used.
- the catalyst itself can be designed according to the invention that Surface structure is dirt-repellent.
- a cooking appliance 1 according to the invention comprises in particular a cooking chamber 2, which is separated from a blower chamber 4 via an air baffle 3.
- the air baffle 3 has at least one inlet and outlet opening, not shown Air circulation between the cooking space 2 and the blower room 4.
- a fan wheel 10 In the blower chamber 4 are a fan wheel 10, two radiators 11, 12, a plurality of one Catalyst housing 13 attached catalyst elements 14 and an impact surface for Separation of solid and / or liquid particles in the form of a separation ring 15 arranged.
- An inner radiator 11 is concentric with the fan wheel 10 to the inner radiator 11, an outer radiator 12, concentric to the outer radiator 12 the separator ring 15 and concentric to the separator ring 15 the catalyst elements 14 arranged.
- the fan wheel 10 then ensures that odor particles and fats from the cooking space 2 into the blower space 4 and passed there to the catalyst elements 14 in order to convert the Allow odor particles and the fats into pure, moist air, which then returns to the Cooking space 2 can be fed. Due to the special arrangement of the impact surface of the separator ring 15 and the heating device 11, 12 in the flow shadow of the impact surface is air very specifically aimed at the catalyst elements 14, so that in particular contamination the heating device 11, 12 can be avoided.
- the cooking device 1 according to the invention in particular fats and other hydrocarbons generated during a cooking process with energy gain dispose.
- the energy content of animal fats is of the order of 1 kWh per 100 g is an inexpensive and energy-saving air purification receive the structure according to the invention without in particular polluting the heating device becomes.
