Description

The invention relates to a door for a household appliance with a first door glass and at least one spaced second door glass. The door further comprises a retaining element, which is connected to the two door panes and the door windows positionally holds each other.

Such a door is for example from the US 4,041,930 known. There are two mutually parallel and plate-like door panels held by rigid circumferential holding elements to each other. The holding elements have Umgriffsbereiche, embrace the edge sides of the door panes. Between these Umgriffsbereichen extends a spacer element which is integrally connected to these Umgriffsbereichen, so that in a direction perpendicular to the planes of the two door panes by this spacer element, the distance between the door panes is held. The retaining element shown in the prior art is designed as a circumferential rigid frame.

A corresponding embodiment is made US 5,029,571 known. On the one hand, the structure can be held on the one hand by these rigid holding elements, but on the other hand problems arise when the door panes deform and, in particular, bend due to temperature influences during operation of the cooking appliance.

Especially with higher demands on the temperature of the individual door windows of a door these are also ventilated. There are different versions. It is essential that the outside, a viewer facing windows, in particular a windshield or outer pane, the door is kept as cool as possible, to cause any burns when touching the door. On the other hand, the cooking chamber facing the slices, in particular a door inner pane, as possible should not be cooled in order to avoid heat from the cooking chamber. To meet these requirements, various approaches to the flow of air are formed in the spaces between the door panes. In order to only purposeful spaces in the context ventilate and dissipate too much air, which would adversely affect energy efficiency, insulation or targeted air locks are installed. Especially in versions in which only rigid support members are present and then also a door is ventilated accordingly, can result from the deformations of the door panes air gaps or openings through which an undesirable air circulation occurs, so that either door panes are then heated undesirable and / or on the other hand door panes are too cold cooled. The main problem of rigid components for sealing in a oven door are thus leaks in the event of deformation of the panes. This can occur due to the temperature differences on the sides of the glass or due to production fluctuations. Due to these influencing parameters, a corresponding orientation of a deformation is not clearly predictable and predictable, so that individual conditions occur depending on the situation.

It is an object of the present invention to provide a door for a household appliance and such a household appliance, with which or at which at least two door panels of a door are held to each other and on the other hand no unwanted leakage openings for the passage of air flow or heat radiation occurs, especially if the Deform door panels due to manufacturing tolerances and / or temperature effects during operation of the household appliance.

This object is achieved by a door and a household appliance according to the independent claims.

A door according to the invention for a household appliance comprises a first door pane and at least one second door pane spaced therefrom. In addition, the door comprises at least one retaining element, which is connected to the two door panes and holds the two door windows positionally to each other. An essential idea of the invention is to be seen in that at least one cover element is formed, which extends in a space between the door panes and beyond parallel to edge sides of the door panes. The cover element is arranged so that it at least partially covers the space between these edge sides in the direction of the edge sides and in a direction perpendicular to the Levels of the door panels is formed elastically deformable. By such a configuration, on the one hand holding the door panels to each other by the holding element is thus made possible. On the other hand, the possibility is also created by an additional separate cover that no leakage openings form at undesirable locations between these door panels by unwanted deformations or manufacturing tolerances. This is achieved by the shape and the local attachment and the elasticity of the cover. Even if at least one of the door panes is deformed, in particular bent, when the temperature of the domestic appliance is being operated, this change in shape can likewise be performed by the elastically deformable cover element, and the space between the door panes remains closed or covered in the area of the cover element , An undesirable air flow between the cover and a door glass is prevented. The cover is thus also an intermediate part, which covers a gap between the mutually parallel and spaced from each other extending edge sides of the two door panes, said cover depending on the length of this cover over which it extends in the direction of these edge sides depends.

Since, in turn, situation-specific with respect to the configuration of the individual and variable shaped doors different requirements are given in this context, a cover may be sufficient here, which extends only over a partial path or a partial length of these parallel edge sides. In other embodiments, it may be advantageous for such a cover element to extend completely and uninterruptedly over the entire length of these mutually parallel edge sides, in particular over the entire length of a possibly shorter edge side of a door pane in comparison to the parallel edge side of the other door pane.

By extending this cover element into the intermediate space, on the one hand a compact design and also a protected arrangement of this cover element, in particular of the elastic part region, is achieved. An undesirable deformation or damage by other forces on this cover can be prevented. In addition, by such positionelle Arrangement of the cover also allows a circumferential mechanical contacting of the two door panes, so that a uniform possible concerns over the length of the cover is made possible on the door panels here as well.

Since the deformability of the door panes occurs in particular in a direction perpendicular to the planes of the door panes, the specific indication of the direction in which the cover element can be elastically deformed is particularly suitable for counteracting these negative circumstances.

The elastic deformability of this cover member is to be understood in particular as meaning that it can change its height dimensioned in the direction perpendicular to the planes of the door panes at specific locations, whereby this may occur only locally due to the local deformation of the door panes. This means that in an elastic deformation not the entire cover over its entire length performs an identical change in height, but that this can also occur locally. Likewise, this means that the cover with respect to its elastic deformability can not only be curved and in this curved position then over the entire length in each case the same height, but that this local height variation is particularly advantageous.

It is preferably provided that the cover element is formed like a rail. The above-mentioned advantages in terms of deformability, compactness and an advantageous, inherent longitudinal stiffness is then particularly favored.

It is preferably provided that the cover element is U-shaped in cross-section and with a leg of the U-shape on one of the second door glass facing surface side of the first door glass and with a second leg of the U-shape on a first door glass facing surface side of the second door glass is applied. This is a particularly advantageous embodiment, as this is on both sides of the U-shape as uniform as possible or the same mechanical contact with the door panels and in view of the deformation and the distance of the door panes, the cover can act particularly highly functional. Basically, by such a design and arrangement of the cover and already one of the preferred direction of deformation of the door glasses counteracting force generated by the cover, so that alone by this shaping and positional arrangement of the cover the above-mentioned negative deformation effect can be counteracted and basically such Deformation can be offered a counterforce.

It is preferably provided that the cover has at least one clip tab, with which the cover engages around an edge side of a door glass and is held on this door glass. On the one hand, this embodiment achieves a fastening possibility of the cover element on a door pane that is very easy to assemble and disassemble. On the other hand, this possibility of attachment of the cover is also very stable and permanently functional, so that the cover is positionally secure on a door glass, which then also attacks the staple tab is held.

Preferably, a plurality of individual and mutually spaced apart clip tabs are provided over the entire length of the cover, so that an improvement in the slip resistance is achieved and an undesirable tilting of the cover in the plane of this door glass is prevented. It is thus achieved at least two-point attachment of the cover on a door glass.

It is preferably provided that at least two separate cover elements are formed, which are arranged extending on respectively opposite edge sides of the door panes in the intermediate space. In particular, these cover elements extend to the opposite and with the door closed vertically oriented edge sides of the door panes.

However, it can also be provided that four such cover elements are provided, each extending in the spaces between two mutually parallel edge sides of the quadrangular and thus four-sided door panes.

Preferably, it is provided that the holding element in a ground state of the door panes, which is characterized by a positional and form-specific state Characterized in that, starting from this then results in deformed when temperature of the door panes or deformed state, this door windows positionally holds such that the cover is compressed in the direction perpendicular to the planes of the door panes biased biased. This is also a very advantageous embodiment, since on the one hand held the positional arrangement of the cover again improved and consistent, on the other hand by biasing a quasi-sided pressures on the door panels and thus would result in a quasi pushing apart the door glasses. As a result of this configuration, the above-mentioned advantages with regard to a force which already counteracts undesired deformation are brought about on the door panes and, on the other hand, if necessary, improved by deforming the door panes. Deforming of the cover element is achieved, since at least one door pane is deformed by the pre-stressing a further complete concern of the cover is achieved on this door glass.

This bias is thus designed to the effect that the two legs of the U-shape are moved toward each other compared to the unloaded ground state.

It is preferably provided that a plurality of holding elements are formed, which are arranged at least in corner regions of the door panes. As a result, a very symmetrical configuration relative to the holding positions of the door panes relative to one another is achieved.

The holding elements are preferably rigid in itself, so that there is no elastic deformation effect to compensate for a door windshield deformation. By at least disposing of the holding elements at the corner regions, a very uniform positional mounting of the door panes relative to one another is also possible on the circumference.

It can be provided that the holding elements are adapted in a form-specific manner to the corner regions in an essentially L-shaped manner and are designed and arranged only in these corner regions. In such an embodiment, it is then provided that extends parallel to the respective edge sides of the door panes between each two holding elements, a cover, so that here in the composite between the cover elements and the holding elements a quasi all around and thus circumferentially sealed disc package results. The seal is to be understood in the context that no unwanted air flows due to leakage due to the deformation of the door panes between such a door glass and a cover occurs. It is therefore not a gas-tight seal to understand and required, but only to understand an embodiment including, in the unwanted leakage air currents, which could have an undesirable positive or negative temperature influence on one or more door panels is prevented.

However, it can also be provided that two cover elements and two retaining elements are provided in an embodiment of quadrangular door windows with thus four edge sides. In such an embodiment, it is then preferably provided that a holding element is U-shaped and extends over the entire length of one edge side of two parallel edge sides of the door panes and still encompasses the corner areas adjoining these edge sides. The holding elements are thus designed as a kind of U-shaped bracket. This is then preferably also at the opposite and extending parallel to further edge sides of the two door panes by a further holding element, which is designed and shaped accordingly provided. Cover elements then extend as connecting parts between the two retaining elements, so that even in such an embodiment, in turn, in particular, a completely circumferential structure is formed from the retaining elements and the cover elements. Again, then a completely sealed design in the sense of the above explanation is achieved.

In an advantageous embodiment, it is thus provided that the holding element is designed in a plane parallel to a door glass or in a plane of the door glass U-shaped. The cover, however, is formed in a plane perpendicular to the planes of the door panes and thus in a plane perpendicular to a longitudinal axis of such a cover U-shaped.

It is preferably provided that a holding element is strip-like and surrounds parallel edge sides of the door panes. This encompassing is then again in a plane perpendicular to the two door windows to understand so that this holding element is quasi a certain edge protection or edge protection for the door panels.

In addition to the relevant protective function, the relative position of the door panes is favored by this configuration, the other.

It is preferably provided that a first retaining element surrounds at least the upper horizontal edge sides of the door panes and a second retaining element engages around at least the lower horizontal edge sides of the door panes. The holding elements are thus formed in this embodiment as upper horizontally extending parts and lower horizontally extending parts.

Preferably, it is provided that a horizontal edge side of a door closer to a cooking chamber of a household appliance door from the at least two door windows over at least 80%, in particular at least 90%, the length of the edge side, is encompassed by the holding element. Since the retaining element in the direction of its longitudinal axis by the shape is very stable and thus very well withstand bending against the longitudinal axis, a very rigid part is provided by this configuration, which also a deformation of a door glass and thus bending the door glass from his Counteracts level out.

It is preferably provided that the holding element holds edge sides of the door panes to be held with play. However, this design involving play is to be understood as meaning that only relatively small movement tolerances are permitted in order to be able to give way to undesirable stresses in the case of temperature influences on the door panes if an immediately rigid reception and spreading of the door panes occurs in the grip areas of the holding elements. As a result, cracking in the door panes can be avoided if necessary. In addition, just by this defined and intended small game-affixed attachment and the functionality of the cover member is taken better account, so that here then the corresponding deformation elasticity of the cover can be improved to advantage.

Preferably, it is provided that a holding element has edge sides of the door panes encompassing gripping areas and at least one spacer bar which extends from a gripping area encompassing the edge of a door pane extends freely cantilevering in the direction of the other gripping area and rests in the mounted state on the door pane surrounded by the other gripping area. As a result, the spacer of the door glass is favored again. On the other hand, this spacer is not vertical and thus perpendicular to the door panels standing element, which would then be rigid in itself. Rather, this spacer bracket is preferably an inclined and / or angled bracket, which then rests with a curved end portion on the inside of the opposite door glass. As a result, relative movements between the spacer bracket of the door glass can be done without them being scratched or damaged. Also, slight movement tolerances can be carried out here, without the spacer bracket applying undesired forces, which would then even act very punctually, on the door glass.

It is preferably provided that the holding element and the cover are non-destructively releasably connected, in particular latched. As a result, it is also possible for these separate parts to be held in a certain positional fixation with respect to one another and, especially in the case of a design in which a completely circumferential concept is realized in the composite of these holding elements and cover elements, the mechanical support of the entire components with respect to one another can also be improved. Last but not least, the above-mentioned sealing concept is improved by such a configuration.

By such a non-destructive detachable connection, which may be an advantageous locking connection, a very quick and user-friendly assembly and disassembly is possible. In an advantageous embodiment, as already mentioned, the total number of cover elements and the total number of holding elements form a peripheral frame.

It can also be provided that the cover and the holding element are non-destructively formed nondestructive.

Furthermore, the invention relates to a household appliance for preparing food, which has a door according to the invention or an advantageous embodiment, and which is designed and arranged for closing a cooking chamber of the household appliance.

In an advantageous embodiment, it is provided that this disc package with the at least two door panes and the at least provided holding elements and at least provided cover elements independently of the door and the household appliance as such is preassembled and can be provided with respect to already pre-assembled assembly for further assembly. It can be provided that a cover made of plastic or metal, for example, as a thin sheet steel or spring plate is formed. A covering element which extends adjacent to an edge side or parallel to the edge sides of door panes is preferably formed in one piece.

Likewise it can be provided that the Umgriffsbereiche a holding element by additional components made of metal or plastic, such as silicone, are formed and mounted between the support member and the respective door glass, in particular to avoid rattling. It can also be provided that more than two separate door panes are held positionally relative to each other by such cover elements and holding elements and that the respective spaces formed by the spacing of the parallel plate-like door panes are correspondingly covered.

The aspects achieved by the holding elements and the cover elements and thus also their functional interaction have a positive influence on the temperature development of the individual door panes, on the energy consumption of the household appliance and thus also on the cooking result. The ventilation of the door can be defined by the respective individual spaces between the door panes. By the effect of the cover also other components, such as side panels of the door are protected from the high temperature from the oven and can be made of less expensive materials. In addition, such a solution creates the freedom to replace more costly sealing materials with more common and less expensive materials, such as spring steel sheet or thin steel sheets.

Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features mentioned above in the description and Combinations of features, as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respectively indicated combination but also in other combinations or alone, without departing from the scope of the invention. Thus, embodiments of the invention are to be regarded as encompassed and disclosed, which are not explicitly shown and explained in the figures, however, emerge and can be produced by separated combinations of features from the embodiments explained.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 is a household appliance 1 for preparing food, such as an oven, shown. The household appliance 1 comprises a housing 2, which surrounds a muffle 3. The muffle 3 limits with its walls a cooking chamber 4, in which food can be introduced for preparing. The muffle 3 has on the front side a charging opening, which can be closed by a door 5. The door 5 is in the exemplary embodiment a flap door which is pivotable about a horizontal axis A. The household appliance 1 further comprises in position and embodiment, for example only shown an operating device 6 with a display unit 7 and controls 8 and 9. The household appliance 1 may also have a hob with cooking zones.

The household appliance 1 can also be equipped with a pyrolysis function.

In Fig. 2 the door 5 is shown in a further schematic representation with sub-components. It has a windscreen or an outer disk 10, which faces the viewer 5 in the closed state of the door 5 and faces away from the cooking chamber 4. In addition, the door 5 comprises an inner pane 11 which, in the closed state of the door 5, is the pane closest to the cooking space 4. In addition, the door 5 comprises at least one, in the exemplary embodiment two, intermediate disks 12 and 13 which are arranged between the front screen 10 and the inner disk 11. The discs 10 to 13 are plate-shaped and oriented parallel to each other, each with a gap 14, 15 and 16 between formed adjacent discs. It is provided that the door 5 is ventilated specifically, on the one hand to keep the windshield 10 as cool as possible, on the other hand, the inner disk 11 as little as possible to cool. For this purpose, very specific air ducts through the door 5 are specified.

In addition, as indicated on one side, a door profile 17 is provided, which is arranged on the windshield 10, and which serves as a carrier for the further discs 11 to 13. A corresponding door profile is also formed on the left opposite side.

By manufacturing tolerances, but in particular by applying temperature during operation of the household appliance 1, the door panes deform, in particular the very hot discs 11 and 12. This is in Fig. 2 shown schematically exaggerated, in which context the inner pane and an intermediate disc correspondingly bulge and thus the completely flat configuration in itself and the completely parallel orientation of the discs is no longer given to each other.

In order to continue to ensure in the context of the ventilation concept, as mentioned above, the best possible and allow no unwanted leakage air currents between the discs and in the interstices 14 to 16, specific measures are taken with representational components.

This is in Fig. 3 in a schematic partial sectional view of an embodiment of components of the door 5 shown. Here, it is provided that at least one cover element 18 is arranged at least between two panes, for example the inner pane 11 and the then directly following first intermediate pane 12. The cover member 18 extends into the gap 14 between the two adjacent discs 11 and 12. The cover 18 is also formed in a straight line and strip-like and extends in this respect perpendicular to the plane of the figure in the y-direction. The cover member 18 extends in the context thus also in a straight line in the direction of the mutually parallel edge sides 11a and 12a of the square door panels 11 and 12. The space 14 is through this Covering element 18 completely covered in the z-direction between these edge sides 11a and 12a and covered in the direction of the longitudinal extent, which is dimensioned in the y-direction, of the cover element 18 at least over the length of the cover element 18. Preferably, the cover member 18 is at least as long as the shorter in the y direction edge or the shorter of the two edge sides 11a and 12a.

In addition, it is provided that the cover member 18 in the z-direction and thus in a direction perpendicular to the planes of the door panes 11 and 12, which span in the x-y plane, is elastically deformable or springs formed. The cover member 18 is preferably configured in one piece and molded from plastic or a metal. It is in the cross section perpendicular to the planes in which the door panels 11 and 12 span, and thus formed in an x-z plane with a U-shaped part 19. It is provided that a first leg 19a on one of the first door glass designated inner disk 11 facing surface side 12b of the intermediate disc 12 abuts and another leg 19b of the U-shape on an intermediate disc 12 facing surface side 11b of the inner disc 11 abuts. This U-shape can be compressed in the z-direction, so that the height measured in the z-direction is variable.

In addition, the cover element 18 comprises at least one, preferably a plurality of clip tabs 20, 21 and 22 (FIG. Fig. 4 ). The clip tabs 20 to 22 are also U-shaped in the cross section shown and surround the edge 12a of the washer 12, so that the cover 18 is also held on this washer 12.

By the in Fig. 3 shown dashed lines and the double arrows, the respective elasticity and possibility of movement of the sub-elements is indicated.

In Fig. 4 an embodiment of a cover 18 is shown in a perspective view. It is there, as well as in Fig. 3 , that the leg 19b facing away from the staple flap 20 is longer in the x-direction than the leg 19a. The cover member 18 is according to the embodiment in Fig. 4 also shaft-like or channel-shaped and thus covers over its entire length the gap 14 in the z-direction between the door panes 11 and 12 from.

In Fig. 5 is shown in a further perspective view of an assembled state of two separate cover members 18 and the door panes 11 and 12. In Fig. 3 is the sectional view along the section line III-III in Fig. 5 shown. It can be seen that the two identically constructed cover elements 18 are arranged on respectively opposite, parallel edge sides of the door windows 11 and 12. In this connection, the left-side cover element 18 is arranged parallel to the edge sides 11a and 12a, which represent vertical edge sides in the closed state of the door 5. In contrast, the right-side cover member 18 is arranged to extend parallel to the two edge sides 11c and 12c.

In Fig. 6 is an embodiment of the door 5 is shown in a further perspective view. In contrast to the representation in Fig. 5 Here, in addition to the already explained two vertically extending cover elements 18, an arrangement of holding elements 23 and 24 is shown. In this embodiment shown, it is provided that the holding elements 23 and 24 extend on the one hand over the entire length of the horizontally extending edge sides 11d and 12d and the horizontal edge sides 11e and 12e of the door panes 11 and 12. They are therefore arranged at the top and bottom of the door panels 11 and 12 and extending horizontally. In addition, it is provided in the embodiment shown that the holding elements 23 and 24, which are rigid in itself and in contrast to the cover 18 is not elastically deformable, in the xy plane are also U-shaped. In contrast, the already mentioned and explained U-shape of the cover 18 but realized in the xz plane.

By means of said specific shaping of the holding elements 23 and 24, these are also arranged around the corner regions 12f, 12g, 12h and 12i of the intermediate plate 12. In this embodiment, moreover, it is provided that is provided by the two cover members 18 which extend only in a straight line in the y-direction, and the two holding elements 23 and 24 a circumferentially encircling the four edge sides of the door panes, sealing frame. The seal does not refer here to a gas tightness, but to a tightness with respect to unwanted leakage flows of the ventilation flows generated in the door 5.

The holding elements 23 and 24 provided as separate components on the one hand and the two cover elements 18 on the other hand are non-destructively releasably connected, in particular latched.

In Fig. 7 is in a sectional view along the section line VII-VII in Fig. 6 an embodiment of a holding element shown. In this embodiment, the holding element 23 is designed as multiply angled and thus stepped component, whereby it has a very high rigidity. It comprises wraparound areas 23a and 23b. The Umgriffsbereiche 23a and 23b in turn surround edge sides of the discs 11 and 12. In addition, the holding member 23 comprises a spacer bracket 23c. This extends from the Umgriffsbereich 23b toward the other Umgriffsbereich 23 cantilevered, and he lies in the assembled state, as in Fig. 7 is shown, at the encompassed by the other Umgriffsbereich 23 a door glass. The spacer bow 23c is bent several times, so that it also has a certain elasticity and thereby also in the z-direction is deformable.

In Fig. 8 is in a further perspective view of the door 5, as shown in Fig. 6 is shown in the upper area. The holding element 23 and a lateral cover element 18 can be seen.

In Fig. 9 is an enlarged view of the area I in Fig. 6 shown. Here it can be seen that the holding element 24 is locked with a cover 18 at a Verraststelle 25. For this purpose, a latching nose 26 snaps onto the cover element 18 into a latching receptacle 27 in the holding element 24.

It is preferably provided that the holding element 24 is designed in its shape such that an inner side 11j of the inner pane 11 facing the cooking chamber is encompassed by the gripping area 24a such that preferably a web 24d extends over the entire length of the encompassed edge side, so that Here, too, a certain support and dimensional stability for the inner pane 11 is given.

On the other hand, it is advantageously provided that the Umgriffsbereiche 23 a and 23 b are dimensioned so that the discs 11 and 12 are received therein with a defined play. As a result, a certain movement deformation is allowed.

With regard to the explanation too Fig. 9 is also to mention that so far too Fig. 3, Fig. 5 . Fig. 6 and Fig. 7 such as Fig. 8 The explanations given and explained are also valid in that the two disks 11 and 12 are reversed and thus, as in Fig. 9 set out, then the Umgriffsbereich 23b surrounds the inner pane 11, and the Umgriffsbereich 23a, the intermediate disc 12 engages around.

In Fig. 10 an embodiment is shown in which both an upper support member 23 and a lower support member 24 as shown in FIG Fig. 9 are formed and have corresponding flanges or webs 23d and 24d. These are formed on the previously described Umgriffsbereichen 23a and 24a.

In Fig. 11 a further embodiment of the door 5 is shown in a perspective view. In this embodiment, the holding element 23 and 24 are not designed as U-shaped moldings, but designed only as L-shaped angled parts. They are arranged in the context only in the corners 12f to 12i. In addition, then each separate cover 18 extend between these four holding elements 23 and 24, so that four cover elements 18 and four holding elements 23 and 24 are provided in this embodiment. Again, the respective separate components are locked together, so that here is a circumferentially closed frame formed by these four cover members 18 and these four holding elements 23 and 24 respectively.
