Description

Door for a cooking appliance with specific shape of a

Heat protection element for a holding profile, as well as cooking appliance

The invention relates to a door for a cooking appliance with a windscreen and two in

Height direction of the door arranged holding profiles, which are spaced and arranged parallel to each other on an inner side of the windshield. Furthermore, the door has separate heat protection elements, which are arranged at least on mutually facing side walls of the holding profiles. Furthermore, the invention also relates to a cooking appliance with such a door.

From DE 10 201 1 086 273 A1 a household appliance in the form of a baking oven is known, which also has a pyrolysis function. The local door has a disc package with a windscreen, an inner pane and intermediate washers on. On the windscreen are parallel to each other oriented and vertically arranged

Sidebars or holding profiles designed to hold the discs. These holding profiles are made of plastic. In addition, the door additionally has a separate metal shielding plate, which is arranged in a space between an inner pane and a first intermediate pane adjacent thereto. In cross-section, this shield is Z-shaped and covers the space between the inner pane and the first intermediate disc to the holding profile out. This is intended to protect the retaining profile against undesirably high heat load, in particular in pyrolysis operation. This door is limited in terms of the design and arrangement of this shielding and focused the construction of the door on a pyrolysis door. Again, by the design of the construction of the door a possible other use of the door is limited.

It is an object of the present invention to provide a door for a cooking appliance, which is improved with respect to the prevention of unwanted heat transfer to a retaining profile of the door. It is also an object of the present invention to provide a cooking appliance with a corresponding door. One aspect of the invention relates to a door for a cooking appliance. The door has a

Windscreen and two arranged in the height direction of the door holding profiles, which are spaced and arranged parallel to each other on an inner side of the windshield. The windscreen provides the front when looking at the door

Viewer nearest disc is, which is thus an outer pane and thus almost represents a visual component of the door front. On the other hand, an inside of the front side faces away from the observer when the door is viewed from the front. The door also has separate heat protection elements, which are arranged at least on mutually facing side walls of the separate holding profiles. A heat protection element is strip-shaped and formed in cross-section and thus viewed perpendicular to the longitudinal axis of the heat protection element with an L-shape. This embodiment is a more individual and space-saving

Positioning of a heat protection element allows. In addition, such an embodiment also enables an improved mechanical connection to additional components of the door. Not least is given by such a geometric configuration of the heat protection element, the possibility of two different wall portions of the holding profiles against unwanted thermal

To protect admission.

It is preferably provided that a heat protection element with a first wall of the L-shape at least partially covers the side wall of the associated holding profile and with a second wall of the L-shape is angled oriented to the first wall, at least partially covering a rear wall of the associated holding profile. Thus, the above advantages are further improved and very concrete

Wall areas of the L-shape cover very concrete wall areas of a retaining profile. Especially the mutually facing and thus inwardly directed side walls of the retaining profile as well as then viewed in the depth direction of the door rearwardly oriented and thus facing away from the viewer in a frontal view of the door walls of the retaining profiles are thus improved against unwanted

Temperature exposure protected. In addition, a specific edge protection or corner protection for a holding profile is virtually made possible by this design. Preferably, a heat protection element is integrally formed, so that just in this L-shape then the transition between the two angled mutually arranged walls of the L-shape, which then open directly to each other, are formed without interruption. Thus, the corner of the retaining profile is uninterrupted covered by a heat protection element.

It is preferably provided that a heat protection element has a front wall facing away from the rear wall, on which at least one oriented in the depth direction of the door connecting plate is arranged, which has a latching element. The

Connecting tab plunges into the associated retaining profile in the direction of the windscreen and is latched to the retaining profile with the locking element, which is in particular a hole. Such a configuration allows a very specific space-saving mounting option of a heat protection element on the holding profile itself. Moreover, through this specific orientation the

Connecting tab and the then practically submerged and protected locking in the holding profile itself created a secure connection, even then against unwanted mechanical influences, such as an undesirable

Impact of other components, is protected. In addition, this configuration thus virtually achieves a multi-sided encompassing or then also clamping of the heat protection element on the retaining profile, so that the secure, fixed positioning is again improved. Through the latching connection here is a non-destructive detachable connection created that can be easily assembled and disassembled.

It is preferably provided that viewed in the width direction of the door, the heat protection element is arranged laterally next to at least one intermediate disk of the door, in particular in the width direction is arranged without overlapping with the intermediate disc. As a result, viewed in the width direction, such a heat protection element is positioned maximally to the side and thus to the outside. A space or a space between an intermediate disc and another disc is thus virtually free of such a heat protection element. As a result, then the access to the heat protection element is easier. It is in that

Connection then no longer in the space between a washer and a further disc immersed or in particular no longer completely arranged therein, as is the prior art.

In an advantageous embodiment, it is provided that the heat protection element is arranged to remove the intermediate disc disassembly. This is particularly advantageous in connection with the above-mentioned embodiment. This can be a

Washers are removed without a heat protection element would have to be dismantled before. This makes assembly easier and faster.

It is preferably provided that the heat protection element has an angled base plate which has a cross-sectionally L-shape. On this base plate webs, in particular embossed webs are formed. In the assembled state of

Heat protection element on the associated holding profile are the webs on the

Holding profile fitting and the base plate to the holding profile spaced thereto

arranged. By such a configuration is thus achieved that a minimal direct contact between the heat protection element and the holding profile occurs. As a result, an undesirable transfer of heat from the heat protection element to the holding element can be avoided.

It is preferably provided that between a heat protection element and the associated holding profile, a hollow chamber is formed as an isolation chamber, which is defined by at least one opening in the heat protection element and / or at least one opening in the retaining profile can be ventilated. This is another very advantageous embodiment for preventing unwanted heat transfer from a gap between an intermediate disc and another disc on the retaining profile,

in particular via the heat protection element to generate. By this hollow chamber is formed, an additional thermal insulation pad is created between the holding profile and the particular about said webs only line-like heat protection element by the corresponding air space is formed there. By this advantageous embodiment, that here also a defined ventilation and thus a defined air flow can be generated by this hollow chamber, this thermal insulation effect is further improved. This defined air flow through the hollow chamber can by appropriate arrangement and shaping automatically generated by components of the door, so that automatically adjusted due to thermodynamic conditions, the air flow. However, it can also be provided that such a defined air flow is generated by a representational means, such as a small fan, which may be arranged in the door or in the cooking appliance itself.

It can be provided that a heat protection element is a galvanized element and / or has a heat-insulating coating. As a result, the thermal shielding effect of the heat protection element is further improved and thus the retaining profile even better protected against undesired thermal loading.

Preferably, it is provided that the door has a trained as a separate holding part transverse bar which extends in the width direction of the door between the holding profiles and is arranged on the inside of the windshield, wherein a

Heat protection element can be attached to the holding part. This creates an individual and stable connection of the heat protection element to an additional part of the door which is additional to the retaining profile. The positional safety is thereby increased again.

It is preferably provided that the heat protection elements are screwed to this cross bar.

In a further advantageous embodiment it can be provided that the

Heat protection element has at least one holding element or a holder, which is designed to hold at least one intermediate disc of the door. The

Washer, of which at least one is present, is between the

Windscreen and the inner pane and spaced from these two discs arranged. This holding element may be formed as a retaining clip which engages around a lateral edge region of the intermediate disc. The holding element can then be formed in the context of quasi as trough-like element. However, other embodiments of the retaining element are provided by which other holding functions are created, for example, a clamping element may be provided. A door can in addition to the windscreen and the inner pane at least one

Have intermediate disc. It can also be provided two such separate intermediate discs.

Another aspect of the invention relates to a cooking appliance with a door according to the stated aspect or an advantageous embodiment thereof. The cooking appliance has in particular a housing in which at least one cooking chamber is designed for preparing food. The oven is in particular closed at the front by said door. The door can be arranged to pivot on the housing. The door may be disposed at a lower end of the housing and pivotable relative to the housing about a horizontal axis, which is thus oriented in the width direction. The door may be in the context of a hinged door, so that in this case only such a pivoting movement is made possible about this axis of rotation. Even in the fully open state of the door, this door is then outside the

Housing arranged. However, it can also be provided that the door is a retractable door. This means that the cooking appliance in the housing, in particular below the cooking chamber, has a storage space which is separated from the cooking space and in which the door can be pivoted in during opening. Such retractable doors are actually known in the general public.

However, the door may also be one which is pivotable about a vertical axis relative to the housing. For this purpose, it can be arranged on the left side or the right side (when viewed from the front) pivotally on the housing.

The cooking appliance may be an oven, which in particular may also have a pyrolysis function. The oven may additionally also have a microwave cooking function and / or a steam cooking function. However, the cooking appliance may also be just a microwave cooking appliance or only a steam cooking appliance.

In an advantageous embodiment it can be provided that the cooking appliance additionally has a heat tray, in particular a heat drawer, which is below the

Cooking chamber is formed. This heat compartment is preferably closed by a separate door, which may be a front wall of a drawer, the front side and can not be closed by the door that closes the cooking chamber. In this warmth compartment Food can be kept warm or dishes such as plates or the like can be heated.

Another independent aspect of the invention relates to a door for a cooking appliance. The door has a windscreen and two arranged in the height direction of the door holding profiles. The windshield is with respect to their position in a front-side view of the door closest to the viewer disc. In particular, this is to be seen accordingly when the door has a disc package with at least two separate, such plate-like disc elements. As discs such elements are referred to, in addition to their plate-like configuration and at least partially transparent, so it can be seen through the door. In particular, a pane made of real glass can be formed.

The separate holding profiles are spaced and arranged parallel to each other on an inner side of the windshield. The inside of the windscreen is the side that faces away from the viewer when viewing the front of the door. The door also has a separate to the windscreen and the holding profiles holding part, which is designed as a cross bar. This cross bar extends in the width direction of the door between the holding profiles and is on the inside of the windscreen

arranged. This cross bar is designed as pyrolysis configuration bar, so that the door is configurable as pyrolysetaugliche door for the cooking appliance. This is given to the effect that the pyrolysis configuration strip has at least one fastening part. In particular, at least one additional pyrolysis component can be attached to this fastening part, with which the retaining profiles formed from plastic are attached

Pyrolysebetrieb the cooking appliance are protected from temperature. By such

Design is thus created a door that in terms of their diverse

Use is improved. The door is basically component-equipped in its quasi-basic design that make the door as a door that can be used in a cooking appliance without a pyrolysis function. On the other hand, by providing the pyrolysis configuration bar, the door is then simply expandable to the extent that it is designed as a pyrolysis door and thus can also be used in a cooking appliance which has a pyrolysis function. It is therefore also possible here that a door is provided with a plurality of equal components for the variant of a non-pyrolysis door as well as for the variant of a pyrolysis door and then individually configurable so that it is virtually expandable as a pyrolysis door. This is then easily made possible by the specifically provided components. Just by the design of the holding profiles made of plastic in the context of a weight-minimized solution for both variants is designed, which also in the

Configuration can be maintained as a pyrolysis door. By then simply attaching a Pyrolysezusatzbauteils to a specific representational unit of Pyrolysekonfigurationsleiste, namely on the at least one fastening part, again a simple modular structure is made possible to protect the plastic retaining profiles formed from unwanted heating again. Thus, the door has a very specific component through this pyrolysis configuration bar, which in a simple way allows the door to be configured towards the pyrolysis door. It is then not only the simple configuration of a Pyrolysetür allows, but in particular by the objective embodiment of the Pyrolysekonfigurationsleiste then already a very specific separate component part, namely the Pyrolysezusatzbauteil, simply mechanically attachable. By this preferred

Pyrolysezusatzbauteil is then also a very specific function to achieve, namely the thermal shielding of the plastic retaining profiles.

It is preferably provided that the transverse strip is integrally formed from metal. As a result, it is mechanically stable accordingly and can also fulfill appropriate carrying and holding functions.

Preferably, it is provided that the transverse strip viewed in the depth direction of the door is designed as a thin plate strip, so that the space remains very reduced in this depth direction. Although here in this embodiment, a minimal structure is generated, yet a high rigidity and high mechanical strength of

Cross ledge given. In particular, it is provided that viewed at the end sides of the strip in the height direction enlarged plate areas are formed, which are formed as multi-component attachment areas for further separate components. This strip is therefore quasi thickened at opposite ends viewed in the vertical direction, so that locally specified stability and space for the connection of other different components is made possible. Through this

Embodiment, it is then also possible that a connection area between them end plate areas in turn can be made relatively small and space-saving, yet the mechanical stability of this cross bar is not limited.

It is preferably provided that the components are the pyrolysis additional components and further functional components. As a pyrolysis additional components, for example, bar elements may be mentioned, which are then oriented in the vertical direction and specifically the holding profiles to at least one space to slices of

Cover disc packs and thermally protect in this regard. When

Functional components which are to be understood differently from pyrolysis additional components can, for example, be a handle or a cover for at least one disc of the

Disc packages, especially from above, are considered.

It is preferably provided that the multicomponent attachment regions have at least two different attachment hole pairs for selectively securing different handles as functional components. By such

Design, it is then by this cross bar also allows for

Variations of the door different handles can be easily attached to it. It is then no longer necessary to provide different transverse strips that allow the attachment of different handles, but by this design of a transverse bar with quasi a redundant design of connection hole pairs, these handle variants can be generated.

It is preferably provided that the Pyrolysekonfigurationsleiste is screwed to the windscreen. This is a further very advantageous embodiment, since thus a positionally secure and durable and correspondingly reliable connection is created. An undesired release of the pyrolysis configuration strip from the windshield, as might be the case for example by an adhesive bond, is thereby

locked out.

It is preferably provided that the pyrolysis configuration strip has coupling lugs which engage in the holding profiles for holding the holding profiles, so that the arranged on the inside of the front side in particular with adhesive bonds

Holding profiles by coupling with the Pyrolysekonfigurationsleiste have an additional support. This embodiment is particularly advantageous in that the io

Holding profiles by a simple mechanical connection, namely the adhesive connection, can be attached to the inside. If such an adhesive bond would become loose or become permanently fatigued, retaining the retaining profiles can still be achieved by means of this specific mechanical coupling with the pyrolysis configuration strip, since the mechanical connection between the pyrolysis configuration strip and the retaining profiles is correspondingly stable.

It is preferably provided that the pyrolysis configuration strip has spacer rods, with which the pyrolysis configuration strip bears against the inside of the front pane, so that a flat base plate of the pyrolysis configuration strip is arranged at a distance from this inside. This is another very advantageous embodiment, since thus a minimum direct contact between the windscreen and the

Configuration bar occurs. As a result, an undesirable heat transfer from the pyrolysis configuration strip to the windshield can be avoided.

It is preferably provided that the door has an inner pane spaced apart from the front pane and has a strip-like, separate connecting element. With this connecting element, the inside is fixed. The

Connecting element is in the height direction of the door in an upper area of the

Inner pane arranged and extends in the width direction of the door. This

strip-like connecting element is attached to the Pyrolysekonfigurationsleiste, in particular screwed. This is a further very advantageous embodiment, since thus the position fixing of a specific disk, specifically the inner disk, is achieved particularly advantageously. On the one hand is through this separate

Connecting element in its strip-like design created a space-saving component, on the other hand, the inner pane but contacted over a relatively large length in the width direction and in this regard has mechanical contact. By then still specific mechanical connection of this connecting element to the

Pyrolysekonfigurationsleiste this mechanical connection also stable and secure position allows, on the other hand, no further holes, for example by one of the discs or the like required. Because of this

Pyrolysekonfigurationsleiste is also a very stable support member, this direct connection of the connecting element to the Pyrolysekonfigurationsleiste also has a very beneficial effect on the permanently fixed position arrangement of the inside. Preferably, it is provided that the connecting element surrounds the inner pane at an upper edge of the inner pane, and the connecting element has at least one connecting tongue, with which the connecting element is arranged on a separate holding part of the door. As a result, a particularly secure mounting of the inner pane is achieved on the connecting element. By a trough-like portion of the connecting element, this upper edge of the inner pane is quasi taken or the upper edge of the inner pane dives into this groove-like part of the connecting element. As a result, the inner pane is also particularly supported and a particularly secure position connection between the inner pane and the connecting element is provided. This separate holding part is formed by the pyrolysis configuration bar.

It is preferably provided that the one-piece connecting element has the above-mentioned trough-like subunit, which is designed as Umgriffsrinne. The upper edge of the inner pane is encompassed by this Umgriffsrinne from above and thus virtually roof-like covered. As a result, the upper edge of this inner pane is also protected.

In a further advantageous embodiment, it is provided that the one-piece

Connecting element has a cover plate, which viewed in the height direction from above a gap between the inner pane and one between the

Inner pane and the windscreen arranged intermediate disc covers the door. This is another very advantageous embodiment, since thus the connecting element is designed as a multi-functional part. It is created on the one hand for safe mechanical connection in order to position the inner pane positionally safe, on the other hand to cover a gap between the inner pane and the adjoining intermediate disc and thus an undesirable

Heat exchange between the gap and the area outside of the

To avoid gap.

In an advantageous embodiment, it is provided that this cover plate of

Connecting element rests on an upper edge of the intermediate disc. Thereby the secure positioning is advantageously supported, on the other hand, the covering of this gap in the direction of depth considered virtually leakage-free and hole-free allows.

Preferably, it is provided that the door has a separate, upper and strip-like cover which covers said disks from above, wherein the upper cover is attached to the pyrolysis configuration strip. This upper strip-like cover, which is also referred to as top panel, thus represents an upper

final visual component of the door. By also this cover at the

Pyrolysis configuration bar is attached, the mechanically stable connection is supported advantageous. This Pyrolysekonfigurationsleiste thus represents individually a multi-binding component and thus also a central fastening part for the attachment of other separate components of the door.

Preferably, this upper strip-like cover is screwed to a connection lug of the pyrolysis configuration strip. By such a tab, the

Usually oriented according to projecting or free-standing, then the assembly can be easily done and a local mechanically stable connection can be created. In particular, by screwing this is also permanently enabled and also allows by such a specific non-destructive detachable connection and a reversible assembly and separation.

It is preferably provided that the upper cover, which extends in an advantageous embodiment in the width direction over the entire width of the door, having a receptacle with rib-like boundaries. By this recording with the rib-like boundaries is also possible that a connecting strap of the

Connecting element is guided during insertion of the connecting strap into the receptacle. As a result, the target position is achieved quickly and safely during assembly and then the connection, in particular screwing, safe and easy.

It can be provided that the connecting element with the upper cover in particular additionally by clip connections or

Snap connections or locking connections is connected. This achieves additional stabilization of the connection. Preferably, it is provided that the door is configured as a pyrolysis door and the

Pyrolysezusatzbauteile oriented in the height direction, in particular L-shaped

Abschirmleisten are, which are also referred to as heat protection elements.

Preferably, these heat protection elements are each arranged on an inner side of a holding profile facing the other holding profile for thermal shielding of the holding profile.

Another independent aspect of the invention relates to a door for a cooking appliance. The door has at least one windscreen and an inner disk spaced therefrom. The discs are designed as plate-like elements, which are in particular at least partially transparent, so that it is possible to look through them. In particular, the panes can be made of real glass. The discs, which are part of a disc package of the door or form such a disc package are spaced and arranged parallel to each other. The door also has a strip-like connecting element with which the inner pane is fixed in its position. This strip-like connecting element is viewed in the height direction of the door arranged in an upper region of the inner pane and extends in the width direction of the door. This strip-like connecting element surrounds the inner pane at an upper edge of the inner pane, so that this inner pane is quasi immersed with its upper edge dipping into the connecting element. The connecting element has at least one connecting strap, with which the connecting element is arranged on a separate holding part of the door. As a result, a particularly stable mechanical connection is created, so that a particularly secure positioning of the inner pane is possible, which is also permanently fixed. Especially in versions of the door, in which this is designed as a pyrolysis door and thus can be used in a cooking appliance with pyrolysis, this is particularly advantageous. As in the

Pyrolysis operation relatively high temperatures occur, it can come to deformations and due to the effects of the temperature-induced effects also come to forces that would cause a change in position of certain components of the door. In particular, this also applies to the inner pane, which is then positioned closest to the cooking space in the installed state of the door on the cooking appliance and is subjected to the maximum appropriate temperature. By just this inner pane is kept very fixed position by this improved connection, especially in pyrolysis, the above aspects can at least significantly reduced become. As a result, the door is permanently functional and achieved a high level of low wear.

It is preferably provided that the one-piece connecting element a

Has Umgriffsrinne with which the upper edge of the inner pane is embraced from above. As a result, the upper edge is also protected and held particularly stable, so that occurring deformations and forces acting on the inside, can be very well received and even then kept the inner pane, especially at the top, by this very stable connection element in shape is.

It is preferably provided that the one-piece connecting element a

Cover plate, which arranged from above a gap between the inner pane and one between the inner pane and the front glass

Cover washer of the door.

In particular, it is provided that the cover plate on an upper edge of

Washer rests. The holding part is in particular designed as a transverse strip, which thus extends in the width direction.

This holding part is preferably plate-like and arranged on one of the inner pane facing inside the windshield, said holding element has a coupling tab for coupling with the connecting plate.

Tabs are in particular provided in the form of projecting and preferably cantilevered sub-elements, which thus allow a particularly simple assembly, since they are in this respect appropriately accessible and the subregions to be coupled can be easily positioned locally to each other targeted.

Preferably, tabs are strip-like elements which are correspondingly shape-specific and characterized by their exposed position on the respective component.

It is preferably provided that the connecting element and the holding part on the tabs by a non-destructive detachable connection, in particular a

Screw connection, are connected. These types of connections are highly stable and permanently correspondingly resilient. In addition, they can also be solved again in order to make a replacement for replacement purposes or maintenance.

It is preferably provided that the door to the holding part has separate holding profiles, which are oriented in the vertical direction and are arranged on the inside of the front side, wherein the inner pane is arranged in the width direction between the holding profiles. The holding profiles are preferably made of plastic. They form the support elements for the panes of the door, in particular the inner pane and optionally an existing intermediate disc which is arranged between the inner pane and the front pane.

Preferably, it is provided that the connecting strap is arranged in regions form-fitting manner on a retaining profile. As a result, a large-scale concern and stable positioning is possible.

It is preferably provided that the connecting link at least one in

Width direction of the door oriented slot has. As a result, a function adjustment is made possible in the width direction of the door, so that any existing tolerances can be easily compensated.

It is preferably provided that the door has a separate, upper and strip-like cover, which is also referred to as a top panel. These strip-like

Cover covers the at least two panes of the door from above, with the

Connecting tab of the connecting element is connected to the upper cover, in particular screwed.

It can be provided that the connecting element with the upper cover by clip connections or latching connections or

Snap connections is connected. These can also be provided in addition to at least one screw connection.

Preferably, it is provided that the door has a washer arranged between the windshield and the inner disk, which with a separate holder of Door is arranged on the holding part. The holder is fixed in position by the separate connecting element. The strip-like connecting element is therefore also expanded in this respect in its functionality. In addition, it is thus possible to contribute, as it were, also in an indirect manner to the position fixing of the intermediate disk, without the connecting element contacting the intermediate disk directly.

Preferably, it is provided that the cover plate has a free edge open at the edge, in which the holder extends and through which the holder in

Width direction of the door is fixed. Furthermore, the invention also relates to a cooking appliance with such a door.

The oven can also have a microwave cooking function and / or a

Steaming feature. In particular, the cooking appliance 1 also has a

Pyrolysis function on. However, the cooking appliance 1 can also be designed as a pure microwave cooking appliance or as a pure steam cooking appliance.

The cooking appliance 1 has a housing 2, in which at least one cooking chamber 3 is formed, which is bounded by walls of a muffle, not shown. The muffle is received in the housing 2.

In addition, the cooking appliance 1 has a door 4, which is arranged for the front-side closing of the cooking chamber 3. The door 4 is arranged movably on the housing 2. The door 4 may be a hinged door or a retractable door. The door may in particular also have a handle 5. The cooking appliance 1 may also have an operating and / or display device, not shown here.

2, an embodiment of a door 4 is shown in an exploded view.

The door 4 may be formed as a non-pyrolysis door. However, it can be advantageously designed as a pyrolysis door and thus be installed in a cooking appliance 1, which has a pyrolysis function. The pyrolysis door can be configured on the basis of the non-pyrolysis door by additionally fitting additional components to the equal components for the pyrolysis suitability.

The door 4 has a front window 6, which is a plate-like element and

is preferably made of real glass. In the closed state of the door 4, the front window 6 is the one which, when viewed from the front (in the negative depth direction and thus in the negative z direction), is the pane closest to the viewer.

Preferably, this windscreen 6 thus also represents an outer part or a front-side visible component of the door 4. The door 4 also has an inner pane 7. In particular, when the door 4 is a non-pyrolysis door, a disk package of the door 4 is formed, for example, only by these two disks 6 and 7.

However, if the door 4 is a pyrolysis door, it is preferably at least one more
