Description

DOOR FOR A COOKING APPLIANCE WITH A SPECIFIC PANE MOUNT, AND COOKING APPLIANCE The invention relates to a door for a cooking appliance with a front pane and an inner pane arranged at a spacing therefrom. The door additionally comprises a strip-like connecting element by which the inner pane is fixed. This strip-like connecting element as considered in the height direction of the door is arranged in an upper region of the inner pane and extends in width direction. Further, the invention also relates to a cooking appliance with a door of that kind.

A domestic appliance with a corresponding door is known from DE 10 2006 013 521 Al. There, a support device comprises transverse support means provided for the purpose of clamping the front pane and the inner pane. This transverse support means is made of plastics material and formed as an elongate strip. Separately therefrom the door comprises a fastening means which has substantially the form of an L-profile member and which is formed separately from this transverse support means. This transverse support means comprises elements which are constructed as plug means and which can be plugged into complementary plug means in vertically oriented side strips, which are made of sheet metal, so that these transverse support means are secured to these side strips. A screw connection with the front pane is then also carried out by way of these plug means of the transverse support means. However, a door of that kind is constructed only for cooking appliances which do not have pyrolytic operation. This is limited on the one hand by the number of panes and on the other hand by the specific construction of the further components. As a result, the utility of the door is also restricted.

It is an object of the present invention to create a door, which having regard to the construction thereof is simplified with respect to forming variants, for a cooking appliance. It is also an object of the present invention to create a cooking appliance with a corresponding door.

One aspect of the invention relates to a door for a cooking appliance. The door comprises at least a front pane and an inner pane arranged at a spacing therefrom. The panes are constructed as plate-like elements, which are, in particular, transparent at least regionally so that a view therethrough is made possible. In particular, the panes can be constructed from real glass. The panes, which are a component of a pane assembly of the door or form a pane assembly of that kind, are arranged at a spacing from and parallel to one another. The door additionally comprises a strip-like connecting element by which the inner pane is fixed in its position. This strip-like connecting element as considered in the height direction of the door is arranged in an upper region of the inner pane and extends in the width direction of the door. This strip-like connecting element engages over the inner pane at an upper edge of the inner pane so that this inner pane is quasi arranged with its upper edge entering into the connecting element. The connecting element comprises at least one connecting strap by which the connecting element is arranged at a separate holding part of the door. A particularly stable mechanical coupling is thereby created, so that an especially secure positioning of the inner pane is made possible, which is also permanently fixed. This is of particular advantage especially with constructions of the door in which this is designed as a pyrolytic door and thus usable with a cooking appliance with a pyrolytic function. Since relatively high temperatures arise in pyrolytic operation, deformation can occur and, due to the effects caused by the temperature loading, forces also arise which can produce positional change of specific components of the door. This particularly relates to the inner pane, which in the installed state of the door of the cooking appliance is then positioned closest to the cooking chamber and subjected to maximum extent to corresponding temperature. Due to the fact that this inner pane, in particular, is held in a very positionally fixed manner by this improved coupling the above-mentioned aspects can be at least significantly reduced especially in pyrolytic operation. As a result, the door is also permanently functionally capable and has a significantly low degree of wear.

For preference, it is provided that the integral connecting element has a grip channel by which the upper edge of the inner pane is gripped from above. As a result the upper edge is also protected and held in particularly stable manner, so that this can readily accept deformations and forces which arise with respect thereto and act on the inner side, and then also the inner pane is held, especially at the upper edge, by this very stable connecting element in shape.

It is preferably provided that the integral connecting element comprises a cover plate which covers from above an intermediate space between the inner pane and an intermediate pane arranged between the inner pane and the front pane.

In particular, it is provided that the cover plate rests on an upper edge of the intermediate pane. The holding part is formed as, in particular, a transverse strip which thus extends in width direction.

This holding part is preferably of plate-like construction and arranged at an inner side, which faces the inner pane, of the front pane, wherein this holding element comprises a coupling strap for coupling with the connecting strap.

The straps are provided particularly with protruding and preferably freely cantilevered sub-elements which thus enable particularly simple mounting, since they are appropriately accessible with respect thereto and the sub-regions which are to be coupled can be selectively positioned locally relative to one another in simple manner. The straps are preferably strip-like elements which are characterised by appropriate shape specificity and by their exposed position at the respective component.

It is preferably provided that the connecting element and the holding part are connected by way of the straps through a connection, particularly a screw connection, releasable without destruction. These forms of connection are highly stable and can be appropriately loaded over a longer period of time. Moreover, they can also be released again so as to be able to undertake dismantling for exchange purposes or maintenance purposes.

It is preferably provided that the door comprises holding profile members which are separate from the holding part and which are oriented in the height direction and arranged at the inner side of the front side, wherein the inner pane is arranged in width direction between the holding profile members. The holding profile members are preferably made of plastics material. They form the support elements for the panes of the door, particularly the inner pane and optionally an intermediate pane which is present and arranged between the inner pane and the front pane.

It is preferably provided that the connecting strap is regionally mechanically positively connected with the holding profile member. A large-area mutual contacting and stable positioning are thereby made possible.

It is preferably provided that the connecting strap has at least one slot oriented in width direction of the door. A functional adjustment in width direction of the door is thereby made possible so that compensation for tolerances which may be present can be made in simple manner.

It is preferably provided that the door has a separate, upper strip-like cover, which is also termed top panel. This strip-like cover covers the at least two panes of the door from above, in which case the connecting strap of the connecting element is connected, particularly screw-connected, with the upper cover.

It can be provided that the connecting element is connected with the upper cover by clip connections or detent connections or snap connections. These can also be provided additionally to at least one screw connection.

It is preferably provided that the door comprises an intermediate pane which is disposed between the front pane and the inner pane and which is arranged by a separate holder of the door at the holding part. The holder is positionally fixed by the connecting element separate therefrom. The strip-like connecting element is thus also increased in its functionality with respect thereto. In addition, there can thus also be contribution quasi in indirect manner to the positional fixing of the intermediate pane without the connecting element directly contacting the intermediate pane.

It is preferably provided that the cover plate has a cut-out -open at the edge -in which the holder extends and by which the holder is fixed in the width direction of the door. Moreover, the invention also relates to a cooking appliance with a door of that kind.

A further aspect of the invention relates to a cooking appliance with a door according to the said aspect or an advantageous embodiment thereof. The cooking appliance comprises, in particular, a housing in which at least one cooking space for preparation of foodstuffs is formed. The cooking chamber is closable by the said door particularly at the front. For that purpose the door can be pivotably arranged at the housing. The door can be arranged at a lower end of the housing and be pivotable relative to the housing about a horizontal axis, which is thus oriented in width direction. The door can in that connection be a flap door so that with respect thereto only a pivot movement of that kind about the axis of rotation is made possible. Even in the completely opened state of the door this door is then arranged outside the housing. However, it can be also provided that the door is a retractable door. This means that the cooking appliance has in the housing, particularly below the cooking chamber, a stowage space which is separate from the cooking chamber and into which the door can be pivoted when opened. Retractable doors of that kind are intrinsically known in general.

However, the door can also be of a kind which is pivotable about a vertical axis relative to the housing. For that purpose, it can be pivotably arranged at the housing on the lefthand side or righthand side (as considered from the front).

The cooking appliance can be a baking oven, which can also have, in particular, a pyrolytic function. The baking oven can additionally also have a microwave cooking function and/or a steam-cooking function. However, the cooking appliance can also be only a microwave cooking appliance or a steam-cooking appliance.

In an advantageous embodiment it can be provided that the cooking appliance additionally has a keeping-warm compartment, such as, in particular, a warming drawer, which is formed below the cooking chamber. This keeping-warm compartment is closable at the front by a separate door, which can be a front wall of a drawer, and is not able to be closed by the door which closes the cooking space. Foodstuffs can be kept warm in this keeping-warm compartment or dishes such as plates or the like can be heated.

A further independent aspect of the invention relates to a door for a cooking appliance. The door comprises a front pane and two holding profile members arranged in the height direction of the door. The front pane is a pane which with respect to its position in the case of viewing the door from the front is closest to the observer. In particular, this can be appropriately seen when the door comprises a pane assembly with at least two separate plate-like pane elements of that kind. Designated as panes are elements of a kind which apart from the plate-like form thereof are also at least regionally transparent so that it is possible to look through the door. In particular, a pane can be constructed from real glass.

The separate holding profile members are arranged at a spacing from and parallel to one another at an inner side of the front pane. The inner side of the front pane is in that case that pane which is remote from the observer when viewing the door from the front. Moreover, the door comprises a holding part which is separate from the front pane and from the holding profile members and which is constructed as a transverse strip. This transverse strip extends in width direction of the door between the holding profile members and is arranged at the inner side of the front pane. This transverse strip is constructed as a pyrolysis-configuration strip so that the door can be configured as a pyrolysis-suitable door for the cooking appliance. This is due to the fact that the pyrolysis-configuration strip has at least one securing part. In particular, at least one pyrolysis auxiliary component, by which the holding profile members constructed from plastics material have temperature protection in the case of pyrolytic operation of the cooking appliance, is mountable on this securing part. By virtue of a design of that kind, a door is thus created which is improved with respect to its universality of use. The door is in principle in its quasi basic form equipped with components in such a way that the door is designed as a door which can be used even in the case of a cooking appliance without a pyrolytic function. On the other hand, through the provision of the pyrolysis-configuration strip the door can then also be developed in simple manner in such a way that it is formed as a pyrolysis door and thus also usable in a cooking appliance having a pyrolytic function. It is thus also made possible here for a door to be provided with a plurality of identical components for the variants of a non-pyrolytic door and also for the variants of a pyrolytic door and then able to be individually configured in such a way that it can be quasi developed as a pyrolytic door. This is also made possible in simple manner by the specifically provided components. Particularly through formation of the holding profile members from plastic, there is formed in that connection for both variants a weight-minimised solution which can be retained even in the case of configuration as a pyrolytic door. Through, specifically, simple mounting of a pyrolysis auxiliary component on a specific actual unit of the pyrolysis-configuration strip, namely on the at least one securing part, a simpler and more modular construction is also made possible here in such a way as to protect the holding profile members of plastics material from undesired heating. The door thus has, through this pyrolysis-configuration strip, a quite specific component which in simple mode and manner enables configuration of the door in the direction of the pyrolytic door. There is then not only made possible simple configuration of a pyrolytic door, but also -particularly through the actual design of the pyrolysis-configuration strip -then an already quite specific separate component part, namely the pyrolysis auxiliary part, can be mechanically mounted in simple manner. Through this preferred pyrolysis auxiliary component a quite specific function can then also be achieved concomitantly, namely thermal screening of the holding profile members of plastic.

For preference it is provided that the transverse strip is integrally constructed from metal. It is thereby appropriately mechanically stable and can also fulfil appropriate supporting and holding functions.

It is preferably provided that the transverse strip as considered in depth direction of the door is constructed as thin plate strips so that the constructional space in this depth direction remains very reduced. Although in this embodiment a minimal construction is then created, nevertheless a high degree of stiffness and high level of mechanical load-bearing capability of the transverse strip is given. In particular, it is provided that at the end sides of the strip as considered in height direction enlarged plate regions are formed, which are constructed as multi-component coupling regions for further separate components. This strip is therefore quasi thickened at opposite ends as considered in height direction so that here a locally specific stability and space for the coupling of other, different components, is made possible. By virtue of this design it is then also made possible for a connecting region between these end plate regions to be able to be in turn designed to be relatively small and space-saving, yet the mechanical stability of this transverse strip is not restricted.

It is preferably provided that the components are the pyrolysis auxiliary components and further functional components. By way of example, strip elements can be mentioned as pyrolysis auxiliary components, which strip elements are then oriented in vertical direction and specifically cover the holding profile members towards at least one intermediate space relative to panes of the pane assembly and thermally protect with respect thereto. By way of example, a handle or a cover for at least one pane of the pane assembly, particularly from above, can be regarded as functional components to be understood as different from pyrolysis auxiliary components.

It is preferably provided that the multi-component coupling regions have at least two different coupling hole pairs for selectable securing of different handles as functional components. It is then also made possible, through an embodiment of that kind, by way of this transverse strip to be able to secure different handles thereto in simple manner for variant formation of the door. It is then no longer required to provide different transverse strips to enable securing of different strips, but through this design of one transverse strip with a quasi redundant layout of coupling hole pairs these handle variants can be produced.

It is preferably provided for the pyrolysis-configuration strip to be screw-connected with the front pane. This is a further, very advantageous construction, since a positionally secure and also appropriately long-term load-bearing connection is thus created. An undesired loosening of the pyrolysis-configuration strip from the front pane, such as could be the case through, for example, a glue connection, is thereby excluded.

It is preferably provided that the pyrolysis-configuration strip has coupling straps which engage in the holding profile members for holding the holding profile members so that the holding profile members arranged at the inner side of the front side particularly by glue connections have an additional mounting through coupling with the pyrolysis-configuration strip. This embodiment is particularly advantageous in that the holding profile members can be secured by a simple mechanical connection, namely the glue connection, at the inner side. If a glue connection of that kind were to loosen or fatigue over time, retention of the holding profile members can, however, still be achieved by this specific mechanical coupling with the pyrolysis-configuration strip, since the mechanical connection between the pyrolysis-configuration strip and the holding profile members is appropriately stable.

It is preferably provided that the pyrolysis-configuration strip comprises spacer rods by which the pyrolysis-configuration strip bears against the inner side of the front pane, so that an areal base plate of the pyrolysis-configuration strip is arranged to be spaced from this inner side. This is a further very advantageous construction, since minimal direct contact between the front pane and the configuration strip thus arises. As a result, an undesired transfer of heat from the pyrolysis-configuration strip to the front pane can be avoided.

It is preferably provided that the door comprises an inner pane arranged at a spacing from the front pane and has a strip-shaped separate connecting element. The inner side is fixed with this connecting element. The connecting element is arranged in an upper region of the inner pane in the height direction of the door and extends in the width direction of the door. This strip-like connecting element is secured to, particularly screw-connected with, the pyrolysis-configuration strip. This is a further very advantageous embodiment, since the positional fixing of a specific pane, i.e. specifically the inner pane, is thus achieved particularly advantageously. On the one hand, there is created by this separate connecting element in its strip-like construction a space-saving component which, on the other hand, nevertheless contacts the inner pane over a relatively large length in width direction and has mechanical contact with respect thereto. By virtue of the then specific mechanical coupling of this connecting element to the pyrolysis-configuration strip it is also made possible for this mechanical connection to be stable and positionally secure and on the other hand no further bores, for example through one of the panes or the like, are required. Since this specific pyrolysis-configuration strip is also a very stable support part, this direct coupling of the connecting element to the pyrolysis-configuration strip also has a very advantageous effect on the permanent positionally-fixed arrangement of the inner side.

It is preferably provided that the connecting element embraces the inner pane at an upper edge of the inner pane and the connecting element comprises at least one connecting strap by which the connecting element is arranged at a separate holding part of the door. As a result, a particularly secure mounting of the inner pane at the connecting element is achieved. This upper edge of the inner pane is quasi received by a channel-like subregion of the connecting element or the upper edge of the inner pane enters this channel-like part of the connecting element. As a result, the inner pane is also arranged to be especially protected and a particularly positionally secure connection between the inner pane and the connecting element is created. This separate holding part is formed by the pyrolysis-configuration strip.

It is preferably provided that the integral connecting element comprises the channel-like sub-unit, which is constructed as a grip channel, already discussed above. The upper edge of the inner pane is embraced from above by this grip channel and is thus covered in quasi roof-like manner. The upper edge of this inner pane is thus also protected.

In a further advantageous embodiment it is provided that the integral connecting element comprises a cover plate which, as considered in height direction, covers from above an intermediate space between the inner pane and an intermediate pane, which is arranged between the inner pane and the front pane, of the door. This is a further very advantageous construction, since the connecting element is thus also formed as a multi-functional part. In that connection there is on the one hand created a secure mechanical coupling in order to be able to arrange the inner pane to be positionally secure and on the other hand an intermediate space between the inner pane and the intermediate pane connected therewith is covered and thus an undesired heat exchange between the intermediate space and the region outside the intermediate space is avoided.

In an advantageous embodiment it is provided that this cover plate of the connecting element rests on the upper edge of the intermediate pane. As a result, secure positioning is advantageously assisted and on the other hand the covering of this intermediate space is made possible in virtually leakage-free and hole-free manner as considered in depth direction.

It is preferably provided that the door comprises a separate, upper strip-like cover which covers the stated panes from above, wherein the upper cover is secured to the pyrolysis-configuration strip. This upper strip-like cover, which is also termed top panel, thus represents a visible upper closure component of the door. Due to the fact that this cover is also secured to the pyrolysis-configuration strip, the mechanically stable coupling is advantageously assisted. This pyrolysis-configuration strip thus then individually represents a multi-coupling component and thus also a central securing part for the securing of further separate components of the door.

This upper strip-like cover is preferably screw-connected with a coupling strap of the pyrolysis-configuration strip. Through a strap of that kind, which is usually oriented to be appropriately protruding or cantilevered, mounting can then be carried out in simple manner and a local, mechanically stable connection created. This is also made possible permanently through the screw connection and, in addition, a reversible joining together and separation are also made possible by a specific connection of that kind which is detachable free of destruction.

It is preferably provided that the upper cover, which in an advantageous embodiment extends in width direction over the entire width of the door, has a receptacle with rib-like boundaries. It is also made possible by this receptacle with the rib-like boundaries that a connecting strap of the connecting element is guided during introduction of the connecting strap into the receptacle. As a result, the target position is rapidly and securely achieved during mounting and then the connecting, particularly the screw-connecting, is also made possible in secure and simple manner.

It can be provided that the connecting element is additionally connected with the upper cover by, in particular, clip connections or snap connections or detent connections. An additional stabilisation of the connection is thereby achieved.

It is preferably provided that the door is configured as a pyrolysis door and the pyrolysis auxiliary components are oriented in height direction, particularly L-shaped screening strips, which are also termed heat protection elements. These heat protection elements are preferably each arranged at an inner side, which faces the other holding profile member, of a holding profile member for thermal screening of the holding profile member.

A further independent aspect of the invention concerns a door for a cooking appliance. The door comprises a front pane and two holding profile members which are arranged in height direction of the door and at a spacing from and parallel to one another at an inner side of the front pane. The front pane in that case represents, when the door is considered from the front side, the pane closest to the observer, which is thus an outer pane and thus quasi also represents a visible component of the door at the front side. An inner side of the front side is accordingly remote from the observer in the case of consideration of the door from the front side. Moreover, the door comprises separate heat protection elements which are arranged at least at mutually facing side walls of the holding profile member separate therefrom. A heat protection element is of strip-shaped construction and has an [-shape as considered in cross-section and thus perpendicularly to the longitudinal axis of the heat protection element. By virtue of this embodiment, a more individual and space-saving positioning of a heat protection element is made possible. In addition, through an embodiment of that kind an improved mechanical coupling to additional components of the door is also made possible. Not least, through such a geometric construction of the heat protection element it also becomes possible to protect two different wall regions of the holding profile members from undesired thermal loading.

It is preferably provided that a heat protection element with a first wall of the L-shape at least regionally covers the side wall of the associated holding profile member and together with a second wall of the [-shape, which is oriented at an angle with respect to the first wall, at least regionally covers a back wall of the associated holding profile member. The above-mentioned advantages are thus further enhanced and quite specific wall regions of the L-shape cover quite specific wall regions of a holding profile member. Particularly the mutually facing and thus inwardly directed side walls of the holding profile member as well as the walls, which are oriented rearwardly as considered in the depth direction of the door and thus remote from an observer in the case of considering the door from the front side, of the holding profile members are thereby protected in improved manner from undesired temperature loading. Moreover, a quasi specific edge protection or corner protection for a holding profile member is also made possible by this embodiment.

A thermal protection element is preferably of integral construction, so that specifically in the case of this L-shape the transition between the two walls, which are arranged at an angle with respect to one another, of the L-shape, which also then directly communicate with one another, is then also formed to be free of interruption. The corner region of the holding profile member is thus covered in interruption-free manner by a heat protection element.

It is preferably provided that a heat protection element comprises a rear wall which is remote from the front pane and at which at least one connecting strap, which is oriented in depth direction of the door and has a detent element, is arranged. The connecting strap enters the associated holding profile member in direction towards the front pane and is detented with the detent element, which is, in particular, a hole, at the holding profile member. Through an embodiment of that kind a very specific space-saving possibility of securing a heat protection element to the holding profile member itself is made possible. Moreover, through this specific orientation of the connecting strap and the detenting, which is then virtually recessed and protected, in the holding profile member itself there is created a secure connection which is also then protected from undesired mechanical influences, for example undesired hitting by other components. Moreover, through this embodiment a quasi multi-sided embracing or also clamping of the heat-protection element to the holding profile member is thus also achieved so that the securely fixed position is further improved. A connection, which is releasable without destruction and can be simply mounted and demounted, is also created here by the detenting connection.

It is preferably provided that the heat protection element as considered in the width direction of the door is arranged laterally adjacent to at least one intermediate pane of the door, particularly arranged to be free of overlapping with the intermediate pane in width direction. As a result, a thermal protection element of that kind as considered in width direction is positioned maximally towards the side and thus towards the outside. An intermediate space or a constructional space between an intermediate pane and a further pane is thereby quasi free of a heat protection element of that kind. Access to the heat protection element is thereby then also simpler. In that connection, there is then no longer entry into the intermediate space between an intermediate pane and a further pane or, in particular, no longer complete arrangement therein, as in the prior art.

In an advantageous embodiment it is provided that the heat protection element is arranged to be free of demounting for the purpose of removal of the intermediate pane. This is advantageous particularly in connection with the above-mentioned construction. As a result, an intermediate pane can be removed without a heat protection element having to be demounted beforehand. Mounting is thereby simplified and made more rapid.

It is preferably provided that the heat protection element has an angled base plate which has an L-shape in cross-section. Webs, particularly stamped webs, are formed on this base plate. In the mounted state of the heat protection element on the associated holding profile member the webs bear against the holding profile member and the base plate is arranged at a spacing from the holding profile member. It is thus achieved through an embodiment of that kind that there is minimal direct contact between the heat protection element and the holding profile member. Undesired heat transfer from the heat protection element to the holding element can thereby be avoided.

It is preferably provided that there is formed between a heat protection element and the associated holding profile member a cavity as an insulation cavity which can be ventilated in defined manner by at least one opening in the heat protection element and/or by at least one opening in the holding profile member. This is a further very advantageous embodiment in order to generate an undesired thermal heat transfer from an intermediate space between an intermediate pane and a further pane at the holding profile member, particularly by way of the heat protection element. Due to the fact that this cavity is formed, an additional thermal insulation cushion is created between the holding profile member and the heat protection element, which particularly by way of the mentioned webs bears thereagainst only linearly, in that the corresponding air space is formed thereat. Through this advantageous embodiment, such that here in addition a defined throughflow of air and thus a defined air stream through this cavity can be produced, this thermal insulation effect is further improved. This defined air flow through the cavity can be automatically produced by appropriate arrangement and shaping of components of the door, so that the air flow automatically arises due to thermodynamic conditions. However, it can also be provided that a defined air flow of that kind is produced by physical means such as, for example, a small fan which can be arranged in the door or in the cooking appliance itself.

It can be provided that a heat protection element is a galvanised element and/or has a thermally insulating coating. As a result, the thermal screening effect of the heat protection element is further improved and thus the holding profile member protected to an enhanced extent from undesired thermal loading.

It is preferably provided that the door comprises a transverse strip which is constructed as a separate holding part and which extends in width direction of the door between the holding profile members and is arranged at the inner side of the front pane, in which case a heat protection element can be secured to the holding part. An individual and stable coupling of the heat protection element to a separate part, which is additional to the holding profile member, of the door is thereby created. Positional security is thereby further increased.

It is preferably provided that the heat protection elements are screw-connected with this transverse strip.

In a further advantageous embodiment it can be provided that the heat protection element comprises at least one holding element or a holder, which is constructed for holding at least one intermediate pane of the door. The intermediate pane, of which at least one is present, is arranged between the front pane and the inner pane and spaced from these two panes. This holding element can be constructed as a holding clip which engages over a lateral edge region of the intermediate pane. The holding element can in that connection then be constructed quasi as a channel-like element. However, other forms of the holding element can also be provided, by which other holding functions are created, for example a clamping element can also be provided.

A door can have at least one intermediate pane additionally to the front pane and the inner pane. Two separate intermediate panes of that kind can also be provided.

Identical or functionally identical elements are provided in the figures with the same reference numerals.

A cooking appliance 1 constructed for preparation of foodstuffs is shown in Fig. 1 in a simplified illustration. The cooking appliance 1 can be a baking oven. The baking oven can additionally have a microwave cooking function and/or steam-cooking function. In particular, the cooking appliance 1 also has a pyrolytic function. However, the cooking appliance 1 can also be constructed as a pure microwave cooking appliance or as a pure steam-cooking appliance.

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

In addition, the cooking appliance 1 comprises a door 4 arranged for closing the cooking chamber 3 at the front side. The door 4 is arranged at the housing 2 to be movable. The door 4 can be a flap door or a retractable door. The door can also have, in particular, a handle 5. The cooking appliance 1 can, moreover, comprise a control and/or indicating device, which is not shown here.

An embodiment of a door 4 in an exploded illustration is shown in Fig. 2. The door 4 can be constructed as non-pyrolytic door. However, in advantageous manner it can be constructed as a pyrolytic door and thus be incorporated in a cooking appliance 1 having a pyrolytic function. The pyrolytic door can be configured on the basis of the non-pyrolytic door in that, in particular, additional components with suitability for pyrolysis can be installed to supplement the same components.

The door 4 comprises a front pane 6 which is a plate-shaped element and preferably constructed from real glass. In the closed state of the door 4 the front pane 6 is that which in the case of viewing from the front (in negative depth direction and thus in negative z direction) is the pane closest to the viewer. This front pane 6 thus preferably also represents an outer part or a frontal visible component of the door 4.

The door 4 additionally comprises an inner pane 7. Particularly when the door 4 is a nonpyrolytic door, a pane assembly of the door 4 is formed by, for example, only these two panes 6 and 7.

If, however, the door 4 is a pyrolytic door then preferably at least one further intermediate pane 8 is provided, preferably two intermediate panes 8 and 9 of that kind. The pane assembly then comprises three or four separate plate-like, spaced-apart panes oriented parallelly to one another.

The door 4 additionally comprises a first holding profile member 10 which [is oriented] in height direction (y direction) of the door 4, which is also the height direction of the cooking appliance 1. Further, the door 4 comprises a second holding profile member 11 which is similarly oriented in height direction and is arranged parallel to and at a spacing from the first holding profile member 10. The two holding profile members 10 and 11 are constructed for holding the panes. The holding profile members 10 and 11 are constructed from plastics material in the illustrated example. In particular, the holding profile members 10 and 11 are secured to an inner side 6a of the front pane 6 by adhesive connections. In addition, the door 4 comprises a strip-like separate connecting element 12, which is an integral, separate component. This strip-like separate connecting element 12 is constructed from, in particular, metal.

Moreover, in an advantageous embodiment the door 4 comprises a separate holding member which is constructed as a transverse strip 13, which thus extends in width direction. In particular, this transverse strip 13 is of integral construction, particularly of metal. This transverse strip 13 is also especially constructed as a pyrolysis-configuration strip. The door 4 can thereby be configured as a pyrolysis-suitable door for the cooking appliance 1. For that purpose this transverse strip 13 in its function as a pyrolysis-configuration strip has at least one securing part which is integrated and thus constructed integrally therewith. In particular, there can be mounted at this at least one securing part of this pyrolysis-configuration strip a pyrolysis auxiliary component separate therefrom. For example, a pyrolysis auxiliary component can be a strip-like cover for a holding member 10, 11.

The transverse strip 13 has a middle web 14 with which there is connected at each end a plate region 15 or 16 thickened in height direction (y direction). In particular, as considered in depth direction this transverse strip 13 is constructed as a thinner plate strip. The plate regions 15 and 16, which are enlarged at these ends of the strip and which are examples of securing parts, are constructed particularly as multi-component coupling regions 17, 18 so that preferably a respective plurality of further separate components of the door 4 can be arranged thereat, particularly connected therewith.

In that regard it can also be provided that these multi-component coupling regions 17 and 18 each comprise two different coupling fans so that at least two different coupling hole pairs are created. These can then be oriented for selectable fastening of different handles 5 to the door 4. A handle 5 additionally represents a functional component which is, in particular, a component different from a pyrolysis auxiliary component. The connection of different kinds of components to this transverse strip 13 is thus made possible, which thus represents a central coupling element of the door 4.

In particular, it is provided that the transverse strip 13 is screw-connected with the front pane 6. For that purpose, screw holes 19 and 20 are provided in the front pane 6, by way of which the screw-connection with the transverse strip 13 by screws 12 is effected. In particular, the handle 5 is then also screw-connected with the transverse strip 13 by way of these screw holes 19 and 20.

Furthermore, in an advantageous embodiment it is provided that the transverse strip 13 additionally has coupling straps 23 and 24. These coupling straps 23 and 24 extend in, in particular, width direction and thus in the plane in which quasi a base plate 22 of the transverse strip 13 extends. The base plate 22 is formed by, especially, the web 14 and the plate regions 15 and 16.

In the embodiment these coupling straps 23 and 24 are integrally formed at the outermost ends of the plate regions 15 and 16.

In addition, the transverse strip 13 comprises two connecting straps 25 and 26 which are preferably constructed as strip-like elements at the outer ends of the plate regions 15 and 16. These connecting straps 25 and 26 extend rearwardly in the depth direction of the door 4 and protrude in free cantilever manner with respect thereto.

In advantageous manner it is provided that the connecting element 12 has individual integrated connecting straps 27 and 28 which bear directly against these connecting straps 25 and 26, in particular are connected together at these connecting straps, particularly screw-connected.

The connecting straps 27 and 28 are arranged at the opposite ends of the strip-like connecting element 12 and are similarly formed as strip-like freely projecting elements.

Moreover, in an advantageous embodiment the door 4 comprises a further, separate component in the form of an upper strip-like cover 29, which is also termed head panel. This upper cover 29 in the installed state of the door 4 covers the pane assembly from above. This upper cover 29 also has, for example, several openings 30 through which air can escape from the door 4, particularly the intermediate spaces between the panes 6 to 9.

This upper cover 29 is preferably secured to the transverse strip 13, particularly screw-connected. This upper cover 29 represents a further example of a functional component.

Furthermore, in an advantageous embodiment, when the door 4 is to be constructed and configured or is configured as a pyrolytic door, it can be provided that the door 4 comprises two further separate heat protection elements 31 and 32. These heat protection elements 31 and 32 are preferably formed from metal and as strip elements. They are formed to be L-shaped in a cross-section and thus perpendicularly to the longitudinal axis thereof.

If these heat protection elements 31, 32, which are constructed as thermal screening elements at the holding profile members 10 and 11, are installed, then in an advantageous embodiment they can, apart from direct securing to the holding profile members 10 and 11, in an optional design also be additionally secured to the transverse strip 13. Here, for example, a mounting or clamping thereat can then be provided. In addition, a screw-connection can be provided.

The door 4 is shown in partly assembled state in Fig. 3, but with the upper cover 29 and the strip-like connecting element 12 still shown in the demounted state. Moreover, here, too, still further holders 33 and 34 are shown, by which at least one intermediate pane is held and is secured to, particularly screw-connected with, further holding straps 35, 36 (Fig. 2) of the transverse strip 13. The holding straps 35, 36 are, particularly like the connecting straps 25, 26, further examples of securing parts of the pyrolysis-configuration strip.

As can also be seen in Fig. 3, the connecting straps 27 and 28 also extend perpendicularly to the longitudinal direction of the strip-shaped connecting elements 12 and, in particular, in the depth direction of the door 4.

An enlarged detail of Fig. 3 is shown in Fig. 4 in a perspective illustration. It can be seen here that the base plate 22 is arranged at the transverse strip 13 at a spacing from the inner side 6a. For that purpose it is provided that webs 37, particularly stamped webs 37, by which the transverse strip 13 bears directly against the inner side 6a are formed. As a result, there is only minimal direct contact between the transverse strip 13 and pane 6. As can additionally be seen, the coupling strap 24, which is oriented in width direction, enters into a slot-like cut-out 38 in a vertical side wall 39 of the holding profile member 11, whereby the positional securing already discussed above is achieved. Even if an adhesive connection, by which the holding profile member 11 is glued over a front wall 40 to the inner side 6a, is at least diminished in its holding effect the positional location at least in height direction is maintained by way of the preferably screw-connected transverse strip 13 and the plug connection, which is interengaging with respect thereto, in the coupling strap 24 and the entrance 38. The coupling strap 23 is correspondingly also formed to be engaging in a corresponding slot-like opening in the holding profile member 10 in width direction.

The door 4 together with its components according to Fig. 3 and to Fig. 4 as viewed from above is shown in Fig. 5. It can be seen here that the connecting element 12 rests by its connecting strap 27 on the connecting strap 26 so that the respective bores align. The screw-connection can be effected by way of these.

Moreover, it can be seen that this connecting element 12 has an integrated grip channel 41, which thus is a preferably U-shaped profile member. This grip channel 41 embraces from above the upper edge 42 (Figs. 2, 3 and 4) of the inner pane 7. This upper edge 42 is thus grasped by the grip channel 41 and thus this upper edge 42 enters into this grip channel 41. The connecting element 12 has, directly connected with or communicating with the grip channel 41, a cover plate 43 which extends in depth direction and covers from above an intermediate space 47 (Figs. 8, 9) between the inner pane 7 and the directly following first intermediate pane 8. As can be seen in Fig. 5, this cover plate 43 rests on an upper edge 44 of this intermediate pane 8.

Moreover, it can be seen in Fig. 5 that the connecting element 12, particularly this cover plate 43, has a cut-out 45 which is open at the edge and into which the holder 34 enters. An advantageous arrangement is thereby also created here, so that the holder 34 is also positionally located in a specific manner in width direction (x direction) by this connecting element 12), wherein in addition a more compact and space-saving construction is achieved in depth direction.

The illustration in Fig. 5 is shown in Fig. 6 in a somewhat rotated perspective different therefrom.

The upper cover 29 with a view into the interior of this upper cover 29 is shown in Fig. 7 in a perspective part illustration. In addition, the connecting element 12 is also shown.

As can be seen here, this upper cover 29 has a receptacle 46, which is laterally bounded by boundary walls 48 and 49. These boundary walls 48 and 49 are constructed as integrated ribs. In that respect a specific guidance of the connecting strap 27 is thus also achieved.

The door 4 is shown in a perspective sectional illustration in Fig. 8, wherein here the upper embracing of the grip channel 41 at the upper edge 42 of the inner pane 7 can be seen. Furthermore, the covering, which is achieved from above, of the intermediate space 47 between the inner pane 7 and the first intermediate pane 8 by the cover plate 43 of the connecting element 12 is shown here.

The vertical sectional illustration of the door 4 is fully shown in Fig. 9.

The door 4 is shown in Fig. 10 in completely assembled state.

In turn, a part detail of the door 4 is shown in Fig. 11, in which the secured state of the protection element 31 at the holding profile member 10 can be additionally seen.

As can be seen here, the heat protection element 31 has a first wall 50.

This first wall 50 of the L-shape of the form of the heat protection element 31 covers an inner side wall 51 of the holding profile member 10 relative to the intermediate space, particularly between the inner pane 7 and the first intermediate pane 8 and thus towards this intermediate space 47. Moreover, this heat protection element 31 has a second wall 52 which completes the L-shape and which is thus oriented to be angled, particularly by 90°, with respect to the first wall 50 and communicates therewith. A connecting strap 54 is integrally formed at this further second wall 52, which at least partly covers this rear wall 53 at a rear side of the holding profile member 10 from the outside or from behind. A detent element 54a, which is here constructed as a cut-out, is formed at this connecting strap 54. A mating detent element 55, which is arranged at the inner side or in the cavity region of the holding profile member 10, detents in this detent element 54a. This connecting strap 54 is oriented in depth direction and thus forwardly towards the front pane 6 and enters into a cavity 56 of the holding profile member 10. The securing and, in particular, this detenting are thus present in this cavity 56 of the holding profile member 10.

Correspondingly, the further heat protection element 32 is arranged at the holding profile member 11.

The door 4 is shown in perspective view in the region of the holding profile member 10 in Fig. 12. This heat protection element 31 can be seen. It thus bears at the inner side and rear side and therefore also directly adjacent, in covering manner, to the corner region between the inner side wall 51 and the rear wall 53 of the holding profile member 10. It can also be provided that the heat protection element 31 is additionally connected with the transverse strip 13, in particular screw-connected. Here, too, by way of example a coupling to the connecting strap 25 can be provided.

The illustration in Fig. 12 is shown from above in Fig. 13, but the upper cover 29 is here removed. In addition, the connecting element 12 is also removed here. The two connecting straps 54 preferably provided here are shown.

It is preferably provided that the walls 50 and 52 of the heat protection element 31 form a base plate of the heat protection element 31 at which webs, particularly stamped webs, are formed. As a result, the heat protection element 31 does not bear over the whole area against the holding profile member 10, but only by way of these webs. It is thereby achieved that the walls 50 and 52 are arranged at a spacing from the holding profile member 10, particularly the inner side wall 51 and the rear wall 53.

A cavity as a thermal insulation chamber is formed, in particular, between the heat protection element 31 and the holding profile member 10, particularly between the base plate, which is formed by the walls 50 and 52, and the holding profile member 10. As a result, in advantageous manner transfer of heat to the holding profile member is avoided in enhanced manner. In particular, it can also be provided that this cavity can be ventilated in defined manner. For that purpose, preferably at least one opening can additionally be formed in a wall 50 and/or 52 of the heat protection element 31 and/or at least one opening can be formed in the holding profile member 10, particularly at one of the boundary walls adjoining in that respect the holding profile member 10.

It can also be provided in an advantageous embodiment that the connecting straps 27 and 28 of the connecting element 12 have slots oriented in width direction so that the positioning of the connecting element 12 in width direction relative to the other components, particularly the transverse strip 13, is adjustable.

In advantageous manner the heat protection elements 31 and 32 as considered in width direction of the door 4 are arranged laterally adjacent to at least one intermediate pane 8, 9, in particular are arranged to be free of overlapping the intermediate panes 8 and 9 in width direction. It is especially provided that the heat protection elements 31 and 32 are arranged to be free of demounting for the purpose of removal of the intermediate pane 8 and/or the intermediate pane 9. This means that for removal of an intermediate plane 8 and/or 9 these heat protection elements 31 and 32 do not have to be demounted.
