Out EP 0 028 328 B1 an oven arrangement is known in which the front of the oven over the entire surface with a cooking appliance door in the form of a glass door is closed.

Out DE 103 49 313 A1 an oven is known, the cooking appliance door has a door interior which is bounded laterally by two extending in the outer direction side cheeks. In the side cheeks air inlet openings are incorporated to allow from the side air into the cavity of the side cheeks. For cooling the door interior in its upper and particularly strong heat underlying door interior lead from the uppermost portion of the side walls door ventilation openings from the side to the door interior, so that the air located in the side walls can get into the upper door interior. The air heated in the door interior can be relieved via top-side door ventilation openings emerge from the cooking appliance door at the top. A disadvantage of such an arrangement is that only the upper region of the cooking appliance door is cooled.

Out DE 198 53 758 C2 is a oven door known, which has three spaced-apart viewing window. To cool the oven door is not closed at the side and in the lower area but open, so that can develop in the spaces between the door panes used air flow for cooling. Out EP 0 255 413 B1 For example, a cooking appliance door is known which has lower-side door ventilation openings and upper-side door ventilation openings, so that air can flow through a door interior. A disadvantage of such cooking appliance doors, however, is that the air is completely uncontrolled due to only a convection caused by heating convection and therefore causes uneven and insufficient cooling of a viewing window.

Out DE 35 18 060 C2 and DE 40 38 796 C2 Cooking appliance doors for a microwave oven are known in which two viewing windows are arranged parallel to each other. For spacing the two viewing windows is arranged between these door plate. The door panel supports in lateral marginal areas of the outer of the window and extends to the outer edge of the inner of the two windows and then a piece in parallel over an outside edge region of the inner window. Accordingly, the inner window is smaller in lateral extent than the outer window.

EP 0 964 208 A1 concerns the area of ovens with refrigerated door. For this purpose, an oven has a muffle, a door, an upper ventilation duct, a blower and at least one inner air passage in the door, wherein: the upper ventilation duct has at least one suction duct and at least one pressure duct; an area for directing air from inside to outside the furnace is located in or above the door, the portion of the area on the inside of the furnace is adjacent to the exit of the pressure channel, the portion of the area on the outside of the furnace is at the level of the wall of the door on the outside of the furnace is; the inner passage has at least one orifice in the guide region and at least one upper orifice adjacent the inlet of the suction channel; and wherein: a first circulation of outside air subsequently passes through the inner passage, its upper opening, the suction passage, the fan, the pressure passage, and the guide portion to open to the outside of the furnace; a second outside air circulation subsequently passes through the internal passage, its orifice and the guide region to open to the outside of the furnace; the air of the second circulation is directed outside the furnace, above the air of the first circulation, at the level of the duct. This type of oven is used in particular for cooking in the home.

It is the object of the invention to improve a cooking appliance door using simple means with a view to a more uniform cooling. The object is achieved by a cooking appliance door according to the respective independent claims. Advantageous embodiments are in particular the dependent claims individually or in combination removed.

According to the invention, accordingly, a cooking appliance door with at least one door ventilation opening on at least one side of the cooking appliance door for introducing air for cooling purposes into a door interior and at least one door ventilation opening for discharging the air from the door interior, wherein arranged in the door interior two louvers for guiding the air flowing inside the door interior are. By means of such air guiding devices, an air stream can also be conducted into regions of the door interior, for example into a lower and central lower region, so that even such regions are cooled by an air flow. The louvers are thus advantageously used for targeted guidance of the air flowing inside the door interior. Such louvers and Luftleitstege can be particularly preferably used in conjunction with side of the cooking appliance door arranged door ventilation openings, but are also advantageously used in conjunction with underside ventilation slots of the cooking appliance door or a lower-side frame member.

According to the invention, the louvers are designed not only in a simple flat but structured manner, in particular with a structured surface, for the purposeful guiding of the air which has entered through the at least one door ventilation opening. Air guiding devices can thus be advantageously designed by means of a special structuring to direct a targeted air flow into desired areas within the door interior or the window opening in order to achieve a desired cooling effect in such areas. In particular, air can thereby be supplied to areas which would not be cooled in the case of a conventional convection flow.

The louvers are preferably designed and / or arranged for swirling the air passing therethrough and / or for forming a turbulent flow in the air guided past it.

The louvers are preferably designed and / or arranged for effecting a nozzle effect and / or spraying action for air guided past the door interior and / or into the window cutout.

According to the invention, the louvers form a section running obliquely between two disks arranged adjacent to one another and at a distance from one another, wherein the louvers engage one of the disks and form a narrowed air passage gap to the other of the disks, in particular an inner disk. As a result, a narrowed air passage gap is formed in particular between an opposite lateral edge of the louvers and the other of the disks, in particular an inner disk. In particular, such an arrangement causes a nozzle effect and at the same time directs an air flow directly to the surface of one of the two panes. Since usually the inside of the disks is heated more than the outside of the disks, the air passage gap is advantageously adjacent to the inside of the disks.

The air guiding devices preferably extend in an upward direction over an entire window cutout or over an entire height between mutually adjacent panes, so that a corresponding guiding action for an air flow can be set over the entire corresponding height. In the case of according to the invention two on opposite sides mutually opposite obliquely arranged louvers is formed when viewing the cooking chamber door around the window pane around a panoramic effect.

The louvers preferably direct an air flow into a lower door area and / or to a control module with controls for operating the cooking appliance. This allows especially sensitive areas to be cooled in a more targeted manner.

Stand alone or in combination so advantageous is a cooking appliance door with at least two mutually parallel disks, which form a door interior and / or a window pane between them, and at least one door vent for introducing ambient air into the door interior and at least one door vent for venting air from the Door interior, wherein the at least one side door ventilation opening directs an air inlet into an area of the two lower thirds of the door interior. Not only an upper region of the door interior or the adjacent panes of the cooking appliance door but also directly a lower region is thereby cooled, so that a risk of injury from burning when the lower outer pane is touched is avoided.

By means of a ventilator, air can advantageously be sucked from the upper side of the closed cooking appliance door into a flow space above a cooking space or above a muffle of the cooking appliance, so that a vacuum is created on at least one door ventilation opening in the upper door region of the cooking appliance door. This leads to an active air circulation or an active intake of ambient air through in particular lateral door ventilation openings and the door interior. At least one door ventilation opening is particularly advantageously arranged in the rear upper door region of the cooking appliance door for discharging air from the door interior into the Flow space above a cooking chamber or above a muffle of a cooking appliance closed with the cooking appliance. Such an arrangement is particularly preferred over an upper-side door ventilation opening, as air leaving the door interior no longer has to be conducted around a corner in order to reach the space above the muffle.

In principle, a fan can alternatively also be advantageously used by blowing air through the cooking appliance door instead of sucking it. Such a fan may e.g. be arranged in the doorway. As a further alternative advantageous alternative solution is the possibility to suck or blow air flow in the opposite direction through the door interior, in which case fresh air from the right or left sides and / or is brought directly from the door top.

On each left and right side of the discs, a plurality of side door ventilation openings is preferably formed.

From a cooking appliance closed by means of the cooking appliance, heated exhaust air is advantageously discharged on the underside from a furnace ventilation opening, the door ventilation opening being spaced from the at least one oven ventilation opening in a door frame of the cooking appliance door.

In the cooking appliance door, a thermally separated space is preferably formed for at least one operating module, wherein at least one air guiding device and / or at least one air guiding bar directs an air flow guided through the door interior in the direction of the thermally separated space.

A window opening is advantageously limited in left and right-hand lateral direction by obliquely arranged between the inner and the outer pane arranged aperture, wherein the diaphragms are designed as spoilers. Such an arrangement offers a plurality of advantages in the form of a targeted guidance of an air flow in the region of the window opening and at the same time a visually appealing panoramic effect by designing the panels as screens.

An outer pane preferably extends as a solid glass pane over the entire width and in particular an entire height of the cooking appliance door. This allows not only a structurally simple installation but also an attractive visual appearance and easy cleaning, since projections and transitions between a frame section and a window section are avoided.

In Fig. 1 a baking oven door 1 of a baking oven is shown, in which a control module 2 is inserted. The oven door 1 covers the front of the oven completely, so that it does not have to have a separate control panel. The oven door 1 has on its outer side or front side a full-surface outer glass pane 4 held only by a narrow metal frame 3. For thermal insulation, the oven door 1 further comprises an inner glass pane 5, whereby a door interior is formed between the panes 4, 5. There may be more glass panes in parallel. In this door interior, a panel 6 is used, which serves as a screen and air flow line, among other things. Through a window cutout as a section 7 in the aperture 6, a viewing window is defined. In the panel 6 ventilation slots 8 are introduced to supply fresh air in the lower part. The upper vent slots are not shown here. The oven door 1 is laterally openable and closable by the handle 9.

Fig. 2 shows an oven 10 with one to Fig. 1 the cooking chamber 11 of the oven 10 is delimited by a muffle 12 open to the front, which is covered by an insulating layer 13. Between the insulating layer 13 and an outer oven panel 14 there is a flow space 15 through which air can flow, preferably substantially moved by a fan 16 in the form of a cross-flow fan. Included in the cooling air circuit is the oven door 1, in particular in that in this embodiment, the oven door can be vented through lateral openings with fresh air, as indicated schematically by the arrows P1. The fresh air flowing into the interior of the door 17 is heated up and flows upward through heat convection and, if necessary, by means of suction through the fan 16, as indicated by the arrows P2. In the upper part of the cooking appliance door 1 are door ventilation slots 18, through which the then warmed up air leaves the cooking appliance door 1. Sucked in by the fan 16, the air then continues to flow around the cooking chamber 11 in the flow space 15, as indicated by the arrows P3, until it leaves the oven 10 through lower oven ventilation openings 19. The associated heating elements, etc. are not shown for clarity.

In this embodiment, located in the oven or cooking appliance door 1 above the cooking chamber 11 and the door ventilation slots 18 a Bedienmodulaufnahmebereich 20, in which a recess in a rear part of the control module 2 is inserted. The operating module receiving area 20 is separated from the cooking chamber 11 opposite region 21 of the cooking appliance door 1 by a bar 22.

The relatively cold control module receiving area 20 is thus kept cooler than the relatively warm door area 21 opposite the cooking space 11, firstly that the hot air is dissipated, as indicated by the arrows P2, and secondly the operating module receiving area 20 is thermally isolated from the door interior 17. In addition, at least one ventilation opening 23, which leads to the flow space 15, is provided on the rear side of the operating module receiving area 20 in the upper side of the cooking appliance door 1. This ventilation opening 23 has the advantage that the operating module 2 is further cooled and at the same time the air temperature in the flow space 15 decreases.

The arrangement shown here also has the advantage that the air inlet openings in particular laterally in the cooking appliance door 1 and above the cooking appliance door 1 spatially from the Ofenauslassöffnungen 19 are separated, so that firstly, the fresh air is sufficiently cool and secondly no escape from a Wrasenöffnung 24 from the cooking chamber 11 escaping vapor can enter the ventilation circuit, which otherwise could lead to a difficult to clean contamination of the interior of the cooking appliance door 1.

The operating module 2 has an inserted into an open-top recess of the front glass front part 25 and an outwardly or forward projecting part 26, which also goes laterally downward beyond the recess. On the externally protruding part 26 controls not shown are present.

In the preferred embodiment of an oven 10, in which now the control module 2 is actively cooled in a cooking appliance door 1. Unlike in Fig. 2 . shown cooking appliance door, in which the present in the top of the cooking appliance door 1 ventilation opening 23 is separated from the Bedienmodulaufnahmebereich 20 through the inner glass 5, this is now sealed by a sealing element 39. By contrast, there is now a ventilation opening 40 for the operating module receiving area 20, as well as an associated vent opening. As indicated by the arrows P4, cooling air is directed through the ventilation opening 40 onto the part 25 of the operating module 2 inserted into the recess and then continues through the vent opening into the flow space 15. This embodiment cools the operating module 2 particularly effective.

Fig. 3 shows in plan view only a section of a cooking appliance door, wherein on the left in the figure, the inside of the cooking appliance door is shown, which closes the muffle 12 and the cooking chamber 11. In a door frame 49, various typical components are used, but these are not all essential for implementation.

On the outside, the door frame 49 receives the outer glass pane 4, which extends according to a particularly preferred embodiment over the entire width and optionally also height of the cooking appliance door. At a distance from the outer glass pane 4 and spaced therefrom by a door interior 17, an inner glass pane 5 is arranged in the door frame 49. In addition, in the door frame 49 optionally inside the inner glass pane 5 more inside glass panes 5 a used, the different glass panes 4, 5, 5a are each spaced by a free space to each other. Components between the outer glass pane 4 and the inner glass pane 5 can accordingly also be inserted between the other of the different glass panes 4, 5, 5a.

For ventilation and cooling of the door interior 17 ventilation slots 8 are formed in a lower region of the cooking appliance door, which allow an air flow from a bottom into the door interior 17. In the case of a cooking appliance door according to Fig. 1 in which a viewing area or window cutout 7 does not extend to the lower edge of the cooking appliance door, it is advantageously possible, instead of or in addition to bottom-side ventilation openings in the cooking appliance door 1, to introduce an airflow from the outer space of the cooking appliance through one or more lateral door ventilation openings 50 the ventilation slots 8 to flow into a lower and central portion of the window section 7. In particular, an air supply to the lower ventilation slots 8 from the side by a lower frame member or aperture member allows the supply of fresh air from a region away from a bottom-side oven ventilation opening.

Particularly preferred is an air flow P0, which through this or other lateral door ventilation openings 50 from a side region of the cooking appliance door 1 laterally in the door interior 17 and in particular in the region of the window opening can flow, as indicated schematically by further arrows P0. The door ventilation openings 50 are preferably formed in a middle and lower lateral region of the cooking appliance door. Due to the lateral intake of fresh air, in particular in embodiments of cooking appliance door with a furnace ventilation opening in the region of the underside of the cooking appliance door 1, it is avoided that heated air, possibly contaminated by vapor, is sucked in again and passed through the door interior 17.

In order to improve the air circulation and / or the directional conduction of air through the door interior 17 and in particular through the region of the window cutout 7, air guiding devices 51, 52 in the form of orifices 51 and / or air guiding webs 52 are arranged in the cooking appliance door 1. Particularly preferred is an arrangement in which a louver 51 in the form of a flat element, for example a flat sheet, rests against one of the two glass panes and leads obliquely through the door interior 17 in the direction of the other glass pane. In the illustrated embodiment, the air guide 51 leads in a first section and preferably door frame 49 slightly spaced first along the inside of the outer glass pane 4 along along, then angled or bent to lead obliquely in the direction of the inner glass pane 5.

The louver 51 preferably extends over the entire height of the window opening 7 or possibly also over the entire height of the mutually adjacent outer and inner glass sheets 4, 5, so that its fluidic effect on the correspondingly required height in particular of the window section 7, but preferably the entire outer glass pane 4 is enough. However, the air guiding device 51 preferably does not extend or, if appropriate, in the region of openings, does not extend all the way to the inner one Glass pane 5 but remains with its lateral edge 54 spaced by a distance from the inner glass pane 5. As a result, one or more air passage gaps d are formed between the lateral edge 54 of the air guiding device 51 and the inner glass pane 5. Such an arrangement causes an air flow from the side directly on the inner glass pane 5, so that it is cooled purposefully. By means of appropriate structuring or shaping measures, such an air-guiding device 51 can also supply specific sections of the window section 7 with an air flow in a targeted manner.

The window opening 7 is delimited in particular by the lateral edge 54 of the louver 51, provided that the louver 51 is formed of an opaque material. The use of opaque materials results in a visually interesting effect with the effect of a panoramic window. In the illustrated embodiment, the louver 51 is not quite up to the side door frame 49, which is why the outer glass 4 is coated on the back with a diaphragm layer 55 to allow a homogeneous design. In principle, however, transparent materials can also be used to form the air guiding device 51.

Conveniently, side door ventilation openings 50 and one or more such louver 51 are not only arranged and formed on one side of the cooking appliance door 1 but also on the opposite side of the cooking appliance door 1. In principle, an arrangement of such louvers 51 in the upper and especially in the Area of the lower side of the cooking appliance door 1 and the window section 7 advantageously used. In the latter case, the ventilation slots would 8 according to Fig. 1 and 3 correspondingly closer to one of the glass sheets 4, 5 arranged. According to first investigations However, the underside ventilation slots 8 may possibly be completely eliminated if by the louver 51, 52 a correspondingly targeted and optimized air flow within the door interior 17 and in particular within the window section 7 is achieved.

For attachment of the louver 51, an exemplary mounting assembly 53 is outlined, which consists of rods which extend vertically through the door interior 17 and to which the louver 51 is attached with clip-like elements. However, any other fastening devices and fasteners can be used up to adhesives.

By way of example, at the rear side of the air-guiding device, in the manner of a diaphragm 51, on one of the fastening arrangements 53, an air-conducting web 52 is sketched as another exemplary air-guiding element. Air guide webs 52 alone or such an air guide in the manner of a shutter 51 can be used to assist in making a fine tuning of a desired flow. In particular, such Luftleitstege 52 can allow fine adjustment of air flow.

Already the use of simply designed air guiding devices 51 enables an advantageous flow of air into the door interior 17 and in particular into the window cutout 7. If required, such an air flow can be further optimized by appropriate structuring and shaping of the walls of such air guiding devices in the form of orifices 51 and air guiding webs 52.

The air flow can also be influenced by the angle of the air guiding device 51 running obliquely through the door interior 17. In addition to the angle of approximately 10 ° -20 ° shown by way of example in the drawing, a course in another is also shown Angle range can be used. Also with a view to an optical design in the sense of a panorama window, the angle of the louver 51 can advantageously be varied.

Fig. 4 shows in exploded view another exemplary embodiment possibility of such Gargerätetür 1 *. This cooking appliance door 1 * in turn consists of a door frame 49, in which an inner glass pane 5 and optionally further inner glass panes are used. For forming the louvers 51, a preferably one-piece guide plate is used with a central recess for forming the window cutout 7 in the door frame 49. Shown are also two more, slightly arched structured and extending in the height direction louvers 51 *, which are used in addition to the integrated integrated in the guide baffles 51. On the outside, after insertion of these components, an outer glass pane 4 is placed, after the fixation in the door frame 49, the cooking appliance door 1 * is assembled in a simple manner substantially ready to install.

In particular, when using a control module 2 in the upper region of the outer glass pane 4 for controlling the functionality of the cooking appliance door, the air flow in the door interior 17 is directed so that the control module 2 undergoes sufficient cooling of preferably both the sides and from below.

Particularly advantageous is in particular the formation of door ventilation openings 18 in the upper rear region of the door frame 49, so that the control module 2 is back-flowed by cooling air. Such rear door ventilation openings 18 in the upper region of the cooking appliance door, in particular in the region of the door frame 49 in each case also allows a discharge of the guided through the door interior 17 Air in the rear direction in the flow space 15, which is formed above the cooking chamber 11.

Advantageously supportive can be as in Fig. 2 sketched fan 16 are used, which is arranged in the region of the flow space 15 and sucks air from the upper front opening of the flow space 15 in this. This creates at the same time a negative pressure at or the door ventilation openings 18, which in turn generates a corresponding negative pressure in the door interior 17, so that the fan 16 ultimately an active air flow through the lateral or optionally further door ventilation openings 50, the door interior 17, the window 7 and the door ventilation openings 18 in the flow space 15 causes.

Fig. 5 shows two exemplary representations of air flows within such Gargerätetür 1, the right illustrations outlined the case of side door ventilation openings 50 over the preferably total lateral height of the cooking appliance door 1 with reference to the illustrated lines. A central and lower region of the window opening 7 is not or only insufficiently flowed through by air in such an arrangement, so that optionally takes place a heat transfer to the outer glass pane 4 and injury to the lower part of the cooking appliance door or the outer glass 4 is. The left-hand illustration shows a particularly preferred embodiment using air guiding devices in the form of orifices 51 and / or air guiding webs 52, which effect an air flow through preferably the entire door interior 17 and the entire window cutout 7. Airflows which not only run along homogeneous flow lines but also form air vortices within the window cutout 7 are particularly advantageous, so that the air flowing through the window cutout 7 can absorb more heat and, if appropriate, can not otherwise be achieved in terms of flow technology Sections can arrive.
