    cooking operation, at least one other baking operating state and / or at least one other pyrolytic operating state.
    The cooking appliance device comprises at least one induction heating unit 20 (see also Figure 5). The induction heating unit 20 is arranged next to the wall of cooking appliance 14. In the present case, the induction heating unit 20 is made as a grill induction heating unit, and has a thermal power of 1,200 W minimum, preferably, 1,800 W minimum, and 5,400 W maximum, preferably 3,600 W maximum. The induction heating unit 20 is intended to induce eddy currents and, therefore, to cause inductive heating.

In addition, the induction heating unit 20 is provided in the second heating operating state at least partially to heat the cooking appliance housing 12 to at least 400 °, preferably at least 450 ° and, advantageously, at least 500 °.

    30
    a large part of the housing unit 50 is arranged above the wall of the cooking apparatus 14 with respect to the direction of the force of gravity 70. The housing unit 50 is provided to partially or completely guide an air flow of exit 18.
    Next, the housing unit 50 is described in more detail with reference to Figures 2 to 4. The housing unit 50 is made at least essentially duct-shaped and approximately or exactly "S" shaped. In addition, the unit of housing 50 is in fluid connection with an interior area of the housing following cooking space 16. In the present case, the housing unit 50 is provided to guide the outlet air stream 18 by a length of 80 mm minimum and 150 mm maximum, preferably 110 mm minimum and 120 mm maximum.
    The outlet air stream 18 connects the cooking space 16 as regards the fluid technique with the outside area (not shown) of the cooking apparatus 10. The outlet air stream 18 is intended to transport the outlet air from the cooking space 16 to the outside area. The exhaust air is a mixture of air, a steam and / or at least one smoke gas. In addition, the outlet air stream 18 is provided to enable compensation of the pressure between the cooking space 16 and the outside area in the heating operating states. As an alternative, the cooking appliance device could have several housing units to guide the output air flow. In addition, a housing unit could be arranged under a wall of cooking apparatus with respect to the direction of the force of gravity. It is also conceived that the housing unit is made in the form of "I", in the form of "L", with a semicircular shape and / or otherwise.

    Likewise, the housing unit 50 has another passage opening 54. The other passage opening 54 is made as an exit opening, has, for example, a round cross section, and defines an output area of the housing. The outlet air stream 18 leaves the housing unit 50 through the other passage opening 54.
    In addition, the housing unit 50 wraps into an intermediate housing area 56. The intermediate housing area 56 connects the passage opening 52 with the other passage opening 54 as regards the fluid technique. In this case, the intermediate housing area 56 has an elongated cross section. Thus, the section of the housing unit 50 that delimits the intermediate housing area 56 is flat, whereby a flat construction can be advantageously achieved. Alternatively, the housing unit could comprise a housing element or more than two housing elements. In addition, the housing elements could be detachable together.

The catalyst unit 30 is intended to influence a chemical reaction in the outlet air stream 18. In the present case, the catalyst unit 30 is provided to facilitate and / or accelerate the chemical reaction. In addition, the catalyst unit 30 is provided to partially neutralize the smell of the outlet air in the heating operating states by means of the chemical reaction. The chemical reaction causes the decomposition and / or destruction of smoke and / or smell particles as well! as of the smoke and / or odorous molecules emitted in the heating operating states. The maximum catalytic effect of the catalyst unit 30 is achieved in this case at a temperature of more than 300 ° and, preferably, more than 350 °. As an alternative, the catalyst unit could be partially or completely made in one piece with the housing unit. Advantageously, at least one inner wall side of the housing unit, which delimits an intermediate area of the housing unit and directed towards the outlet air stream, could be at least partially coated with a catalyst layer and / or be made as a catalyst element.

    The catalyst unit 30 has a catalyst element 32. Observed in the direction of the outlet air stream 18, the catalyst element 32 is arranged in the area of the passage opening 52. In addition, the catalyst element 32 is in contact with the housing unit 50. The catalyst element 32 is connected to the housing unit 50 at least in a drive. In addition, the catalyst element 32 comprises a catalyst layer (not shown). The catalyst layer is made of a catalytically active material. In addition, the catalyst element 32 comprises a catalyst support (not shown). The catalyst support is made of a catalytically inactive material. Observed in the direction of the outlet air stream 18, the catalyst support has a grid-shaped structure. The catalyst support is traversed through multiple openings in parallel to the direction of the outlet air stream 18. The catalyst layer is applied on the catalyst support.
    In addition, the housing unit 50 has a fixing element 58, which fixes the catalyst element 32. The fixing element 58 fixes the catalyst element 32 against the direction of the force of gravity 70. Alternatively, the catalyst element could be fully arranged inside or outside the area of the passage opening. In addition, the catalyst element could be made without contact with the housing unit. Likewise, the catalyst element could be fixed to or housed next to the carriage unit in force drag and / or otherwise. On the other hand, the fixing element could fix the catalyst element in a direction perpendicular to the direction of the force of gravity. In addition, the catalyst support could have a reticular, spongy and / or honeycomb structure. In principle, it is also conceived that the catalyst support does not have openings.
    In the present case, the catalyst unit 30 further comprises another catalyst element 34. Observed in the direction of the outlet air stream 18, the other catalyst element 34 is disposed in the area of the other passage opening 54. In addition, the Another catalyst element 34 is in contact with the housing unit 50. The other catalyst element 34 is connected with the housing unit 50 in shape and force drag. In addition, the other catalyst element 34 comprises another catalyst layer (not shown). The other catalyst layer is made of a catalytically active material, in this case, the same catalytically active material as the catalyst layer. In addition, the other catalyst element 34 comprises another catalyst support. The other support of

    Catalyst is made of a catalytically inactive material, in this case, the same catalytically inactive material as the catalyst support. Observed in the direction of the outlet air stream 18, the other catalyst support has a grid-shaped structure. The other catalyst support is traversed through multiple openings in parallel to the direction of the outlet air stream 18. The other catalyst layer is applied on the other catalyst support.
    The catalyst element 32 and the other catalyst element 34 interact for the catalysis of the outlet air stream 18. Alternatively, the catalyst unit could have only one catalyst element or at least three catalyst elements. Advantageously, at least one catalyst element, advantageously, a catalyst support element, could be made at least as part of a housing unit, in particular, of a housing wall that advantageously delimits an intermediate area. In addition, the housing unit could have another fixing element that fixed another catalyst element against the direction of the force of gravity.
    Also, the cooking appliance device has a heat transmitter unit 40. In this case, the heat transmitter unit 40 is made in one piece. The heat transmitting unit 40 is arranged in an area close to the induction heating unit 20. In this case, the heat transmitting unit 40 is in contact with the induction heating unit 20. In addition, the heat transmitting unit 40 is made in one piece with the housing unit 50 and is made separate from the catalyst unit 30. The heat transmitter unit 40 is thermally coupled with the catalyst unit 30, in particular, with the catalyst element 32 and the other element Catalyst 34. The heat transmitter unit 40 is here composed largely or entirely of a thermoconducting material. In the present case, the heat transmitter unit 40 is composed largely or completely of a ferromagnetic material. Alternatively or additionally, the heat transmitting unit could have several partial parts joined detachably. Also, the heat transmitting unit could be made separate from the housing unit. In addition, the heat transmitting unit could be made in one piece with a catalyst unit and / or with a catalyst element. The heat transmitting unit could also be composed of an alloy of thermoconductive and / or ferromagnetic metals.
    The induction heating unit 20 is provided to inductively heat the heat transmitter unit 40 in the heating operating states. In this case, the heat transmitter unit 40 is provided in the operating states of

    heating to transmit to the catalyst unit 30 a thermal energy caused by the induction heating unit 20. Here, the heat transmitter unit 40 is provided at least to transmit heat by thermal conduction. Therefore, the induction heating unit 20 is provided to heat the catalyst unit 30 by means of the heat transmitter unit 40 such that the catalyst unit 30 reaches a temperature of 350 ° in a maximum time range of 3 min, preferably , in a maximum time margin of 2 min and, advantageously, in a maximum time margin of 1 min. Alternatively or additionally, the heat transmitting unit could be provided to transmit heat by convection and / or thermal radiation. In addition, other heating units, namely induction heating units, could be provided to at least partially heat the heat transmitting unit in the heating operating states. In addition, an induction heating unit and / or another heating unit could be specifically provided, in particular, exclusively, for heating the heat transmitting unit. Basically, it is also conceived that an induction heating unit and / or another heating unit is provided to directly heat a catalyst unit.
    To heat the catalyst unit 30 through the induction heating unit 20, the heat transmitter unit 40 in this case comprises, for example, two heat transmitting elements 42, 44. The heat transmitting elements 42, 44 are connected each other in one piece and are intended to interact with each other to heat the catalyst unit 30. Alternatively, the heat transmitting unit could only have one heat transmitting element or more than two heat transmitting elements. In addition, the heat transmitting elements could be made separated from each other. Also, each of the heat transmitting elements could cause the heating of a catalyst unit separately.
    The first heat transmitting element 42 of the heat transmitting elements 42, 44 is made as a flat heat transmitting element 42. The main extension plane of the first heat transmitting element 42 is arranged approximately or exactly parallel to the main extension plane of the induction heating unit 20. The first heat transmitting element 42 is disposed in the area of the heating unit by induction 20. In this case, the first heat transmitting element 42 is in contact with one of the insulating elements 24, 26 of the induction heating unit 20. Observed in a direction perpendicular to the main extension plane of the unit induction heating 20, the first heat transfer element 42 and
    induction heating unit 20 overlap. In addition, the first element

    25

    35
    Heat transmitter 42 is made as a fastening element of the heat transmitter unit 40. The induction heating unit 20 is provided to inductively heat the first heat transmitter element 42 in the heating operating states. For this, the first heat transfer element 42 is composed of a thermoconducting and ferromagnetic metal. The first heat transfer element 42 is provided to transform the electromagnetic energy of the induction heating unit 20 into a thermal energy by eddy currents. Likewise, the first heat transmitting element 42 is provided to indirectly heat the catalyst unit 30. Alternatively, the first heat transmitting element could be arranged distanced from an induction heating unit. In principle, the first heat transmitting element could also be provided to directly heat a catalyst unit.
    The second heat transmitting element 44 of the heat transmitting elements 42, 44 is made as part of the housing unit 50, namely, as the housing side wall of the intermediate housing area 56. The second heat transmitting element 44 is provided to directly heat the catalyst unit 30. For this, the second heat transfer element 44 is in direct contact with the catalyst unit 30. In addition, the second heat transmitter element 44 is provided to transmit heat from the first heat transmitter element 42 to the catalyst unit 30. To this end, the second heat transmitting element 44 is in direct contact with the first heat transmitting element 42. In addition, in this case, the induction heating unit 20 is provided to heat the second transmitting element of heat 44 in the heating operating states. For this, the second heat transfer element 44 is composed of a thermoconductive and ferromagnetic material. Alternatively or additionally, the heat transmitting unit could have at least one heat transmitting element that is made as a catalyst support and / or that is heated by an induction heating unit in at least one heating operating state. In principle, the second heat transfer element could also be provided to indirectly heat the catalyst unit. For this, the second heat transmitting element could be indirectly connected with the catalyst unit. It is also conceived that the second heat transfer element is made of a material that is not inductively heated. In addition, the second heat transfer element could be provided exclusively for transmitting heat.
    The cooking device also includes a regulating unit 60 (see
    Figures 6 to 8). Observed in the direction of the outlet air stream 18, the unit
    18
    5
    10

    25
    30
    regulator 60 is connected behind the housing unit 50. The regulator unit 60 is intended to regulate the current velocity of the outlet air stream 18. In addition, the regulator unit 60 is intended to adjust in the second operating state of heating, configured as a pyrolytic operating state, a lower current velocity than in the first heating operating state, configured as a baking operating state. Alternatively, the regulator unit could be connected in front of the housing unit. In addition, the regulator unit could adjust the speed of the current regardless of the heating operating states.
    The regulating unit 60 comprises a closing element 64. The closing element 64 is shown in its open state in Figure 7. In the open state, the closing element 64 allows the exit of the outlet air stream 18. In this case, the closure element 64 is made as a cover. In addition, the closure element 64 is mobilely housed next to a gluttony element 66.
    The regulator unit 60 also has a drive unit 68. The drive unit 68 is intended to move the closure element 64 along a predetermined movement path by the glut element 66. In addition, the drive unit 68 is intended to move the closing element 64 from the open state to the closed state, or from the closed state to the open state. In the second heating operating state, the drive unit 68 is provided to move the closing element 64 to the closed state. Furthermore, the drive unit 68 is provided in the first heating operating state to move the closing element 64 to the open state. As an alternative, the regulatory unit could present several closing elements. In addition, a closing element could be made as a sliding door and / or as a panel.
    In addition, the regulator unit 60 has a passage opening 62 (see Figure 7). The passage opening 62 is open continuously in both heating operating states and is intended to enable compensation of the pressure between the cooking space 16 and the outside area. In addition, the passage opening 62 allows, in the closed state of the closing element 64, that the outlet air stream 18 leaves more slowly than in the open state.
    In the open state, the outlet air stream 18 has a current velocity
    at least 0.7 m / s, preferably at least 1.0 m / s, and a maximum of 1.6 m / s,
    preferably, 1.2 m / s maximum. In the closed state of the closure element 64,
    19
    the outlet air stream 18 has a current velocity of at least 0.2 m / s, preferably at least 0.25 m / s and at most 0.4 m / s, preferably at most 0 , 35 m / s. In the present case, the output air entrained in the outlet air stream 18 has a longer contact time with the catalyst unit 30 due to the slowed speed of the current in the closed state of the closure element 64. In this way , the catalytic effect of the catalyst unit 30 is intensified, and at the same time the exchange of fluids between the cooking space 16 and the outer area becomes possible. As an alternative, the regulatory unit could have several passage openings. In addition, a passage opening could be locks.
