Definitions
- the invention relates to a cooking device with a catalyst.
- a device for separating solid and / or liquid particles from a gas volume with at least one impact surface is known, for example, from DE 42 06 846 C2.
- DE 198 24 172 discloses a cooking device with an energy storage and energy extraction system which is connected to a measuring and control system already present in a conventional cooking device, so that heating power can be reduced on the one hand and waste heat can be used on the other.
- An energy storage device can be used during breaks, as is always the case in batch operation or as a result of the cooking process, and or in a prior cooking phases, in which a cooking process requires little or no energy, by means of an, if necessary, additional heating, controlled via the measurement and control system, according to a priority hierarchy to ensure an undisturbed sequence of a cooking process, or are charged by the heat from the exhaust air or excess steam escaping from the cooking space, and then more than in hyperior cooking phases in which the cooking process requires a lot of energy the heating installed to heat the food can deliver energy from the energy storage.
- EP 0 772 514 B1 describes self-cleaning surfaces which are created by artificially implementing a microscopic surface structure as described for the Lotus flower is known, can be realized in hydrophobic polymers or durable hydrophobized materials.
- the object of the present invention is to add a cooking device in which the cooking chamber atmosphere can be cleaned of odors and fat swaths in an energy-saving manner with a simple and compact construction.
- a cooking device with a cooking chamber, a ventilation device, such as in the form of a fan wheel or the like, a heating device and a catalyst, on which air, finally, fats, odor particles and / or hydrocarbons from the cooking chamber can be finely atomized by the ventilation device , which cleans the air directed at it with the release of energy and from which the cleaned air and / or the energy released during cleaning in the form of heat can be distributed into the cooking space via the ventilation device.
- a ventilation device such as in the form of a fan wheel or the like
- a heating device and a catalyst
- the catalyst is arranged at least in areas essentially concentrically around the ventilation device.
- An embodiment of the invention is characterized in that the catalyst is designed in the form of a large number of catalyst elements attached to a catalyst housing.
- an impact surface be arranged at least approximately essentially concentrically around the ventilation device, preferably in the rear third of the cooking space, in the blow-out direction.
- the impact surface is designed in the form of a separating ring for separating solid and / or liquid particles from a gas volume. It is also proposed according to the invention that the heating device is arranged essentially concentrically around the ventilation device, the catalyst is arranged essentially concentrically around the heating device, and the heating direction is arranged at least partially in the flow shadow of the impact surface.
- the heating device is designed in the form of at least one, preferably two, ring-shaped radiators.
- a further development of the invention is characterized by an energy storage system or energy system with catalyst properties.
- the cooking space, the energy storage and / or energy extraction system and / or the heating device is or are at least partially equipped and / or coated with a catalyst.
- the catalyst has a surface with a surface structure in dimensions of up to a maximum of 500 ⁇ m and is self-cleaning.
- the catalyst comprises aluminum oxide and / or platinum.
- the invention is therefore based on the surprising finding that by means of a fan wheel or the like, air, including fat swaths, odor particles and / or hydrocarbons, can be directed in a simple manner onto a catalyst which is converted by fat swaths, smell particles and / or hydrocarbons, in particular by oxidation greases, allows air to be cleaned and, at the same time, generates heat, which on the one hand enables the cooking chamber atmosphere to be cleaned and on the other hand enables the cooking chamber to be heated in an energy-saving manner.
- the catalyst can be used on the one hand in the form of individual, separate catalyst elements and / or on the other hand as a (partial) coating of the chamber and / or of an energy storage and / or energy extraction system.
- the catalyst itself can be designed in accordance with the invention in such a way that its surface structure is dirt-repellent.
- a heating device is arranged in the flow shadow of an impact surface between the fan wheel and the catalytic converter, so that air can be directed even more specifically onto the catalytic converter and at the same time contamination of the heating device is avoided
- Figure 1 is a partial longitudinal sectional view of the cooking device according to the invention.
- FIG. 2 is a cross-sectional view of the cooking device according to the invention of Figure
- a cooking device 1 comprises in particular a cooking space 2, which is separated from a blower space 4 via an air baffle 3.
- the air baffle 3 has at least one inlet and outlet opening (not shown) for air circulation between the cooking space 2 and the blower space 4.
- a fan wheel 10, two heating elements 11, 12, a large number of catalyst elements 14 attached to a catalyst housing 13 and a working surface for separating solid and / or liquid particles in the form of a separating ring 15 are arranged in the blower chamber 4.
- An inner heater 11 is arranged concentrically to the fan wheel 10
- an outer heater 12 is arranged concentrically to the inner heater 1
- the separator ring 15 is arranged concentrically to the outer heater 12
- the catalyst elements 14 are arranged concentrically to the separator ring 15.
- the fan wheel 10 then ensures that the odor particles and fats from the cooking space 2 into the blower space 4 and there onto the Catalyst elements 14 are passed so as to convert the To enable odor particles and the fats into clean, moist air, which can then be fed back into the cooking space 2. Due to the special arrangement of the impact surface of the separating ring 15 and the heating device 11, 12 in the flow shadow of the impact surface, air can be directed very specifically onto the catalyst element 14, so that, in particular, contamination of the heating device 11, 12 can be avoided.
- the cooking device 1 thus makes it possible to dispose of greases and other hydrocarbons which arise during a cooking process with energy gain. Since the energy content of animal fats is, for example, of the order of 1 kWh per 100 g, inexpensive and energy-saving air purification can be obtained with the structure according to the invention without the heating device in particular being contaminated.
