advantageous Embodiments and developments of the module and the cooking appliance according to the invention arise from the dependent ones Claims.

In a particularly advantageous embodiment are at least two exhaust channels (or: Ausblasarme) provided, namely a first blow-out and a second blow-out, wherein the second blow-out at least one, preferably in one or formed by a constriction region of the second blow-out channel Dust area for generating an overpressure or a stagnation in the gas flow in the storage area and wherein the passage opening in the storage area of the second Ausblaskanals is arranged.

Thereby can the gas flow under the overpressure in the jam area through the passage opening into another area transferred to the cooking appliance be or flow. This is particularly advantageous for cooling other parts of the cooking appliance, preferably a microwave waveguide in the presence of a microwave function of the cooking appliance. Furthermore can prevent the penetration of vapor from the cooking chamber into the waveguide be prevented or reduced by generating overpressure in the waveguide.

It may now be designed so that the gas flow at least approximately rectilinear and thus comparatively undisturbed or the flow direction remains substantially the same, and / or the second blow-out be designed so that the gas flow is curved or the Strö flow direction a curved Course takes. As a result, it is possible to increase the blocking effect in the second blow-out channel and to increase the volume flow or throughput in the second outlet Lower possibly blow channel with respect to the first blow-out or remove the exhaust air focus with the greater moisture content on the rectilinear blow-out.

The two blow-out channels preferably branch from a core channel region of the blow-out channel starting at the production side of the blower immediately connected, and / or flow especially in associated separate blow-out areas.

Of the or each intake duct is in general, especially in the built-in cooking appliance Condition of the module, at a bottom of or below the exhaust duct arranged and / or immediately adjacent to the exhaust duct, in particular to the core channel area arranged. This will save a lot of space Construction realized.

Conveniently, sucks the blower In operation, ambient air to mix and cool the from the cooking appliance or cooking space sucked air.

at a cooking appliance, the at least one thermal cooking mode, but no steam cooking mode and has no microwave cooking mode, the through hole is in Ausblaskanal expediently permanently closed or not available or generated.

at a cooking appliance, the at least one microwave cooking mode has, is the through hole in the exhaust duct with a waveguide for conducting the microwaves connected or connectable for blowing air into the waveguide, so that due to the resulting overpressure little or no Steam or vapor and thus no moisture can penetrate. This is particularly advantageous because consequently also the sensitive Magnetron protected becomes.

at a cooking appliance, the at least one steam cooking mode has, preferably (also) the passage opening with the cooking chamber of the cooking appliance in fluid communication brought. In general, now a first closing device (or: closure member) for closing the passage opening in a closed state and at least partially open the passage opening in an open state and a second closing device for closing the Intake duct in a closed state and at least partially open the Intake duct provided in an open state, and preferably also a control device for activating the first closing device and the second closing device. Preferably, the first and the second closing device designed as a gate valve or valve, the / in a final position the corresponding air transfer openings covers. This allows a simple and kosteni conditions Closing mechanism. A short-built shut-off is also space-saving accommodate.

The Operation in steam mode is now generally such that especially about the control device, in the steam cooking operation both closing devices be brought into the closed state or both the intake passage as also the passage opening be closed. This will cause the escape of steam from the oven (at least when the door is closed) prevented. After the steam cooking operation then both closing devices returned to its open state to drain the steam from the oven.

Thus, in operation, one can distinguish three cases occurring alternatively or in any combination:
Case 1: in a thermal cooking mode of the cooking appliance, air and vapor or other gas are sucked out of the cooking chamber by the blower via the intake duct of the module and blown out through the at least one blow-off duct, preferably at least predominantly via the first blow-out duct, and the at least one blow-out region ,
Case 2: in a microwave cooking mode of the cooking appliance, air and vapor or other gas are sucked out of the cooking chamber by the fan via the intake duct of the module and out through the at least one blow-off duct, preferably at least predominantly via the first blow-out duct, and the at least one blow-out area blown out and at least some of the air sucked in by the fan, if necessary with steam, or of the other gas is blown into or onto a waveguide for the microwaves, preferably for generating an overpressure in the waveguide,
Case 3: in a steam cooking mode of the cooking appliance, the through-hole of the blow-off channel on the one hand and the suction channel, in particular on a suction port or on a cooking chamber opening, on the other hand closed and after completion of the steam cooking mode, the through-hole and the suction channel for discharging the excess steam from the cooking chamber again opened and blown on the one hand air, possibly with vapor content, through the passage opening in the cooking chamber and on the other hand aspirated air with steam from the cooking chamber through the intake.

When the intake duct is located directly under the first blow-out duct, the humid air is discharged from the cooking compartment box over this center of gravity. The over the second Air outlet air thus contains a lower moisture content, here outweighs a introduced from the fan ambient air. Advantageously, the substantially drier air guided in the second blow-out channel deviates beyond the passage opening and thus enters the cooking chamber. Due to the faster air exchange, the vapor reduction can be accelerated accordingly, so that when opening the door of the cooking hardly steam exits In a development of the second blow-out via at least one pressure channel with the connection channel or the cooking chamber in combination. The overpressure generating steam is thus also discharged through the second blow-out. To control the steam temperature in the cooking chamber, the overpressure channel advantageously has a steam thermostat, so that a proper operation of the steamer is guaranteed.

In addition, here is a first closure member 12 in the air suction channel 9 arranged. The first closing organ 12 is formed in this embodiment as a longitudinal section T-shaped slide over, wherein a cross bar of the slider within the Luftabsaugkanals 9 , directly on the air transfer opening 10 can be applied to the air transfer port 10 to close.

In the 2c illustrated second side view of the ventilation / cooling module 1 shows, similar to in 1c , again the second blow-out 4 , This is in this case with the second air transition opening 11 formed, via which a connecting channel 13 to the back box 7 leads. The air transfer opening 11 is with a second closure member 14 closed, this is also designed as a longitudinal section T-shaped slide. A crossbar of the slider is within the second Ausblasarmes 4 directly on the air transition opening 11 applicable to keep them closed during the baking and steaming operation. From the connection channel 13 extends overpressure channel 15 with a steam thermostat arranged thereon 16 in the direction of the second Ausblasarmes 4 and flows through a third air transition opening 17 in these.

Because the 2a to 2c . 3a to 3c and 4a to 4c the same embodiment, namely a ventilation / cooling module used in a baking appliance with Dampfgarfunktion 1 in the various functional stages, will be referred to below only on the various operating conditions. Regarding the construction of the in the

3a to 3c and 4a to 4c shown device is at this point to the description of 2a to 2c directed.

In the baking operation of this embodiment ( 2a to 2c ), the ventilation and / or cooling of the baking appliance with Dampfgarfunktion according to the first preferred embodiment. To ensure this, is the first closure member 12 arranged so that the first air transfer opening 10 is open. At the same time that closes in the second Ausblasarm 4 provided second closure member 14 the second air transfer port 11 on the one hand the heat loss in the back box 7 To keep small and on the other hand to avoid that the vaporizing mixture flows back into the oven.

During the steam cooking process, ie during steam generation ( 3a to 3c ) the steam gets in through the door 5 , the first closing organ 12 and the second closure member 14 closed back box 7 held. The fan 8th only sucks in air from the environment to cool the baking machine. This cooling air is delivered via the air outlet channel 2 ie over the first blower arm 3 and the second blow-out arm 4 between the door 5 and the control panel 6 blown out of the baking unit. The by the steam generation in the back box 7 forming pressure escapes through the connecting channel 13 , via the overpressure channel 15 , through the air transfer opening 17 in the second blow-out 4 and is blown out of the baking unit. The steam temperature in the back box 7 is over the steam thermostat 16 controllable.

After completion of a time-defined steam (steam) operation, the steam extraction phase is initiated ( 4a to 4c ). For this purpose, the first closure member 12 of the door 5 closed baking box 7 open, leaving the fan 8th over the air suction channel 9 the no longer needed steam in the back box 7 suck off and over the air exhaust duct 2 can blow out of the baking device. Since the vapor leading Luftabsaugkanal 9 immediately below the first blow-out arm 3 is located, the steam is mainly discharged via this. The over the second Ausblasarm 4 Accordingly, air to be discharged contains a lower moisture content, here one outweighs the blower 8th introduced ambient air. Simultaneously with the first closure member 12 also becomes the second closing organ 14 open. Now in the second blow-out 4 guided, substantially drier air due to the arrangement of the connecting channel 13 at the the storage area 4S having second Ausblasarm 4 over the second air transition opening 11 Dodge and get into the back box 7 , This allows a faster exchange of air in the back box 7 and thus an accelerated vapor degradation. When opening the door of the back box 7 Steam hardly exits from this through the feed opening.

The 5a to 5c show a third preferred embodiment in which the ventilation / cooling module 1 is provided in a baking device with microwave function. In the 5a illustrated plan view of the ventilation / cooling module 1 essentially corresponds

1a and 2a and will therefore not be explained further. 5b shows a first side view of the ventilation / cooling module 1 according to the third preferred embodiment, which is substantially 1b equivalent.

In the 5c illustrated second side view of the ventilation / cooling module 1 shows, similar to in 1c , the second blower arm 4 , Below the second blower arm 4 is a microwave waveguide 18 arranged immediately adjacent and parallel to the Ausblasarm 4 Gradient. A magnetron 19 is located below the microwave waveguide 18 at its fan-side end. Between the second blower arm 4 and the microwave waveguide 18 there is a fourth air transition opening 20 ,

The ventilation and / or cooling of the baking device with microwave function is realized by the same principle as it is used in the classical baking device. It will therefore be the vapors through the first air transition opening 10 over the air suction channel 9 with the help of the blower 8th aspirated. At the same time the fan sucks 8th Air from the environment to the forming lukewarm mixture through the air blower 2 to blow out of the oven. The fourth air transition opening 20 is in the jam area 4S the second Ausblasarms 4 arranged so that here the jammed, substantially dry air over the opening 20 in the microwave waveguide 18 can dodge. This causes the microwave waveguide 18 forms a small overpressure that prevents it from the back box 7 Steam in the microwave waveguide 18 penetrates. In addition, this avoids that the temperature in the microwave waveguide 18 exceeds a bearable measure. The overpressure protects the magnetron 19 also from moisture.
