Description

Refrigerator door

The invention relates to a refrigerator door for a refrigeration appliance, in particular a household refrigerating appliance, according to the preamble of claim 1.

For stand-mounted refrigerators, decoupled appliance doors are widely used. These may have a decorative frame, which is placed on the door outer panel and carries a large-scale decorative element.

From DE 198 56 093 A1 a generic refrigerator door is known, which has a cooling chamber of the refrigeration appliance facing inner lining, an outer lining and an intermediate, produced by foaming heat insulation layer. The door outer lining is not made in one piece, but has two lateral vertical door frame strips, between which a large decorative panel

is provided. This is so intrinsically rigid that it can withstand the foam pressure during the foaming process without deformation. such

Decorative panels can be made of glass material, for example, and be foamed directly with the thermal insulation layer.

The selection of usable decorative elements is therefore limited in DE 198 56 093 A1 to particularly dimensionally stable decorative panels that withstand the foam pressure, while other used in the furniture area thin-walled decorative elements, such as formica, veneer, sheet metal or Plexiglas material due to reduced material stiffness are not suitable.

The object of the invention is to provide a refrigerator door for a refrigeration device, in which all decorative elements used in the furniture sector can be used regardless of their material properties as part of the refrigerator door outer panel.

Under a refrigeration device is in particular a household refrigeration appliance understood, ie a refrigeration appliance for household management in households or possibly in the Catering area is used, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer, a fridge-freezer or a wine storage cabinet.

The object is solved by the features of claim 1. preferred

Further developments of the invention are disclosed in the subclaims.

According to the invention, the refrigeration appliance door has an inner lining facing the cooling space of the refrigeration appliance, an outer lining and an intermediate heat insulation layer produced by foaming. The outer lining is constructed in several parts by a large-area plate element and by lateral door frame strips, between which the large-area plate element is held. The

Plate element is according to the characterizing part of claim 1 is not uniform material and in one piece, but designed as an at least two-piece plate composite. The plate composite has an inherently rigid carrier plate adjacent to the heat insulating layer and an outer side provided on the carrier plate

Decorative element with reduced inherent rigidity. The view protected behind the

Decorative element arranged support plate can be produced without any design claim and designed so that they can withstand the foam pressure during the foaming process for foaming the heat insulation layer readily process reliable. In contrast, the foaming process has no effect on the decorative element, so that the material properties of the decorative element with respect to a

process-safe foaming process play no role. Accordingly, as

Decorative element a thin-walled decorative plate or a foil-like decorative coating are used, which is applied cohesively on the support plate.

Preferably, the edge portions of the support plate and the decorative element of the panel composite according to the invention can be aligned flush with each other at the edge substantially with a continuous transition. The thus formed narrow side or

Edge side of the plate composite is therefore formed without gradation. The provided on the door frame rails holding profile can therefore embrace the plate composite edge without special account adjustment. Alternatively, the edge portions of the support plate and the decorative element on the side edges of the plate assembly can not finish flush, but they can be offset laterally offset by an offset. This results in the plate element edge-side gradation. In this case, if appropriate, only the stepped projection can be encompassed by the retaining profile of the door frame strips, while the recessed edge portion of the plate element remains out of engagement with the retaining profile.

As mentioned above, the side door frame strips may have a holding profile in which the plate assembly is at least partially supported with its side edges. The retaining profile of the side door frame strips may have for receiving the side edges of the plate member facing each other U-shaped grooves. These are each formed by an integrated in the door frame strip groove bottom and by two opposite Wnkelschenkel which are spaced from each other by a groove width. The groove width of the receiving groove, depending on the design of the

Material thickness of the plate composite correspond. Alternatively, the groove width of the grooves in about the material thickness of the above-mentioned stepped

Projection on the side edge of the panel assembly correspond. To form the step-shaped projection, by way of example, the visible-side decorative element can project beyond the carrier plate by a lateral projection. Conversely, the support plate may extend beyond the decorative element by the excess side.

In the event that the support plate and the decorative element terminate substantially flush at the edge, both the support plate and the decorative element can be inserted into the receiving grooves of the door frame strips. In this case, the

Support plate and the decorative element, for example, form a loose plate composite, in which the decorative element can be replaced if necessary, while the

Foam-tight support plate with the heat insulating layer facing, first Wnkelschenkel the receiving groove is connected. In contrast, the decorative element can be loosely held between the support plate and the opposite, second Wnkelschenkel the receiving groove and optionally tool-free disassembled from the retaining profile. By way of example, the decorative element and / or the visible, second Wnkelschenkel the receiving groove may be designed such that under elastically yielding deformation, the decorative element can snap into the retaining profile, that is in Snap connection with the second angle leg of the holding profile can be brought.

The refrigerator door, together with the side door frame strips and upper and lower, horizontally extending end elements each form a door frame, which moves the inner lining and the outer lining on the outside. The upper and lower end elements can each encompass the door frame strips and the inner and outer panels. In this case, the loose mounted in the holding profile decorative element can be supported in the installed position directly on the lower end element. By contrast, the upper end element can have a recessed insertion region for mounting or dismounting the decorative element. About the insertion area, the decorative element can be inserted in about plane-parallel to the support plate from above into the receiving grooves of the holding profile or pushed out of these.

As a result, it is possible for the user, if necessary, to replace the decorative element as desired.

For a perfect appearance of the refrigerator door front, it may be advantageous if the visible side of the decorative element substantially continuously, that is flush, merges into the side door frame strips. Such a continuous or flush transition between the decorative element and the lateral

Door frame strips can be achieved in different designs. According to a first alternative, the carrier plate of the plate assembly may be inserted positively and firmly in the already mentioned receiving grooves of the holding profile. The

On the other hand, the decorative element can be arranged outside the receiving grooves and, in particular, lie opposite a front side of the second, visible side curved leg of the receiving groove via a frontally open visual joint. The material thickness of the decorative element is in this case essentially identical to the material thickness of

Wnkelschenkels, whereby a flush transition between the decorative element and the visible Wnkelschenkel the receiving groove of the holding profile is achieved.

Alternatively, the retaining profile may not be formed by a U-shaped receiving groove, but have a front open recess. This can be bounded by a wnkelschenkel projecting in the depth direction of the door backward and an adjoining, inwardly angled Wnkelschenkel on the each one side edge of the plate assembly rests. Depending on the design of the plate composite may be completely immersed in the recess, resulting in a flush transition between the door frame strip and the plate assembly may result.

The rearwardly projecting angle leg is angled away from the visible side of the door frame strip by one abutting edge. Optionally, only the support plate can be inserted into the recess of the retaining profile, while the decorative element protrudes in the Bautiefenrichtung with an excess over the abutting edge of the door frame strip.

Hereinafter, embodiments of the invention are described with reference to the accompanying figures.

6 and 7 respectively third and fourth embodiments of the refrigerator door in

Views corresponding to FIG. 2. In Fig. 1 is a simplified schematic representation of a fragmentary one

Refrigeration appliance door shown, which is constructed symmetrically to a central axis of symmetry. The refrigerator door has in a conventional manner, a plastic inner lining 1 with projecting spars 3. The inner lining 1 is provided at its free edges 5 with a magnetic seal, not shown, in a receptacle 6 of the

Interior trim 1 is used. On the inner lining 1 borders one

Heat insulating layer 7, which is formed by foaming a liquid starting component. The heat insulation layer 7 connects the inner lining 1 with an outer lining 8 to a largely dimensionally stable door body. According to FIG. 1, the outer cladding 8 has a multi-part construction and comprises a plate element 9 which occupies the door front and which according to FIG. 1 is a plate composite consisting of an intrinsically rigid carrier plate 10 and a visible decorative plate 11. The vertical in the installed position side edges 13 of the plate assembly 9 are supported in accordance with FIG. 1 in a holding section 15 of the side door frame strips 17. The door frame rails 17 are according to the invention e.g. Extruded aluminum bars with consistently constant profile. As is apparent from Fig. 1, the holding profile 15 is arranged directly in the front corner area 16 of the door frame strips 17. From the support section 15 is directly a narrow door side wall 19 in the depth direction y angled backward angled, which is foam-tight connected to the free edges 5 of the inner lining 1. In the side cheeks 19 of the door frame strips 17 is an approximately triangular profiled continuous recessed grip 21 is formed.

The refrigerator door is covered in the assembly position both at its upper edge (Fig. 1) and at its lower edge (Fig. 3) by a horizontally extending end member 23, which may be made of plastic injection molding or of metallic material such as aluminum, for example. The outer contour of the respective end elements 23 is approximately adapted to the contour of the refrigerator door at the top and at the bottom edge and surrounds the interior trim 1 and the

Door frame strips 17 and the plate assembly 9. The termination elements 23 also have hole-like receptacles 18, which are used to support the door on

Refrigeration appliance housing serve.

2, the plate assembly 9 and the holding section 15 of the door frame strips 17 is shown enlarged. Consequently, the door frame strips 17 for receiving the Side edges 13 of the plate assembly 9 each U-shaped, facing each other

Grooves 24 on. These each have a groove bottom 22 and two

Angle leg 25, 26, which are spaced apart by a groove width b. According to FIG. 2, both the decorative element 11 and the carrier plate 10 are in the

Receiving groove 24 used. The carrier plate 10 and the decorative element 11 are dimensioned so that there is a stepless or flush transition to the plate composite side edge 13. The edge portions 12, 14 of the support plate 10 and the decorative element 1 1 are aligned in the depth direction y in alignment with each other. In Fig. 2, the decorative element 11 is not stored in a fixed connection with the support plate 10, but in the gap between the visible angle leg 25 and the support plate 10 loosely. Its gap width is dimensioned so that the decorative element 11 is vertically displaceable in the grooves 24, while the support plate 10 fixed about about an adhesive layer with the heat insulating layer 7 facing

Wnkelschenkel 26 is connected. To increase the support base is the

Plate composite 9 under cross Wnkelschenkel 26 in door side direction x compared to the visible side Wnkelschenkel 25 greatly extended.

In the embodiment shown in FIGS. 1 to 4, the refrigerator door is designed so that the decorative element 11 can be easily replaced by the user. For this purpose, according to FIG. 1, an insertion region 29 is recessed in the upper end element 23, via which the decoration element 11 can be pushed in or pushed out from above in a plane-parallel manner to the support plate 10 in the receiving grooves 24 of the side door frame strips 17. The lower end element 23 shown in FIG. 3, on the other hand, closes the receiving grooves 24 of the holding profile 15 vertically downward, so that the decorative plate 11 can be supported on the lower end element 23.

Alternatively or additionally, according to FIG. 4, the decorative element and / or the visible side leg 25 of the retaining profile 15 can be dimensioned such that under elastically yielding deformation (indicated by arrows in FIG. 4)

Decorative element 11 and / or Wnkelschenkels 25, the decorative element 11 in

Snap connection can occur with the holding profile 15. As can be seen from FIGS. 1 to 4, in the assembled state between the decorative element 11 and the visible side leg 25 of the door frame strip 17 there is a step-shaped transition whose step height h (FIG. 2) corresponds to the thickness of the material

visible side leg 25 corresponds. The peripheral edge of the decorative element 11 is therefore covered by the Wnkelschenkel 25 visible. In contrast, in FIG. 5, an approximately flush transition between the decorative element 11 and the door frame strips 17 can be achieved. In FIG. 5, the retaining profile 15 has no U-shaped grooves 15, but instead a front-side step-like recess. The front open recession is bounded laterally by a wnkelschenkel 31 projecting in the door depth direction y backwards. This is angled around an abutment edge 33 from the visible side 27 (FIG. 5) of the door frame strip 17. At the Wnkelschenkel 31 is followed by a right angle angled support web 34, on which the plate assembly 9 rests. Unlike the previous one

Embodiment, the support plate 10 and the decorative element 1 1 are not in

Los contact, but firmly connected. As a result of the step-like recess which is open towards the front, according to FIG. 5, a visible joint 35 is exposed between the side edge 13 of the panel assembly 9 and the abutting edge 33.

6, another embodiment of a refrigerator door is shown, the door frame strip 17 has a holding profile 15 which is constructed substantially identical to the return shown in FIG. In contrast to FIG. 5 are the

Edge portions 12, 14 of the support plate 10 and the decorative element 1 1 in the lateral direction x not aligned flush with each other. Rather, the edge portion 14 of the decorative element 1 1 in Fig. 6 dominates the edge portion 12 of the support plate 10 to a

Offset m. This results in the side edge 13 of the plate assembly 9, a step-shaped projection which is placed in Fig. 6 as a negative mold on the return of the holding profile 15. The overall height c of the recess is identical to the material thickness of the support plate 10, while the offset m of the decorative element 11 is dimensioned such that its outer edge in the depth direction y is aligned flush with the side cheek 19 of the door frame strip 17. In the direction of the user, therefore, the side cheek 19 is substantially protected behind the decorative element 11, so that the impression of a frameless

Refrigeration appliance door results. In the embodiment shown in FIG. 7, the holding profile 15 of the

Door frame strips 17 formed approximately as shown in FIG. 2. in the

In contrast to FIG. 2, however, the edge section 12 of the carrier plate 10 in the lateral direction x projects beyond the edge section 14 of the decorative element 1 1 by an offset m, so that only the protruding carrier plate 10 is inserted into the receiving groove 24 of the holding profile 15 in FIG , The recessed in the lateral direction decor element 11, however, is disposed outside of the receiving groove 24 and spaced by a forward exposed visual joint 32 of the end face 37 of the visible angle leg 25. The material thickness of the decorative element 1 1 is designed in Fig. 7 so that between the front visible side of the door frame strip 17 and the decorative element 1 1 results in a substantially flush transition.
