Description

Refrigerator door

The invention relates to a refrigerator door for a refrigeration device, in particular a

Domestic 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 refrigerator 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 these two lateral vertical door frame strips, between which a decorative plate is provided as a separate component, which borders directly on the heat insulating layer. The decorative plate is therefore intrinsically stiff to the foam pressure during the

Foaming process to withstand deformation. Such decorative panels may, for example, be made of glass material and be back-foamed directly with the heat-insulating layer.

The two door frame strips are in DE 198 56 093 A1 each with an im

Essentially provided in the door depth direction aligned side cheeks, which merges at one, the front front edge forming lateral wide abutting edge in a visible side front portion. The front section of the door frame strip has on the inside a holding profile, in which the decorative plate is inserted. In DE 198 56 093 A1, the door is limited to design variants in which the lateral

Door frame strips at least partially form the front door, since the door frame strips are visible with the front side viewing section in the direction of the customer. Design variants which do not provide the impression of a frameless appliance door with door frame strips which are visually protected in the direction of the customer's view are not provided in the case of the door structure known from DE 198 56 093 A1. The object of the invention is to provide a refrigerator door for a refrigeration device, in which a simple assembly of the outer lining is made possible and at the same time different design variants of the refrigerator door, in particular a frameless refrigerator door, can be realized in a simple manner.

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 adjacent to the heat insulating layer plate member is supported. The two spaced apart in the door side direction vertical door frame strips have according to the characterizing part of claim 1, a holding profile for the plate member, which is formed substantially without lateral offset directly at the front corner of the door frame strips.

According to the invention, in contrast to DE 198 56 093 A1 dispensed with a large-scale and visible front section of the door frame bar and the holding profile provided directly on the front corner of the refrigerator door. This allows the

Impression of a frameless refrigerator door, in which the lateral

Door frame strips are arranged in the direction of view of the customer substantially protected from view.

The door frame strips each have in the door depth direction backward aligned projecting side cheeks, which connect directly to the retaining profile in the front corner of the door. The side cheek of the respective door frame strip can also in front corner area have an obtuse angled gutter, which is connected to the retaining profile. The narrow gutter is almost not perceived in the direction of the customer as a slightly obliquely outwardly extending visible surface laterally outside of the plate member.

The retaining profile may have in one embodiment, an aligned in the Bautiefenrichtung angle leg, which can laterally border the plate element in the installed position. The angle leg can be plane-parallel to the side wall, but laterally offset inwardly, so that there is a gap between the side wall and the Wnkelschenkel. The hollow before the foaming process

Interspace is filled during foaming with the heat insulation layer. This results in the front corner of the refrigerator door despite low

Cost of materials an extremely dimensionally stable sandwich structure consisting of the outer side cheek, the heat insulation layer and the Wnkelschenkel of the holding profile.

The Wnkelschenkel of the holding profile can pass into a recessed support web, which is angled inward in the door side direction. The support web forms during assembly of the outer lining a depth stop on which the plate element is placed.

In addition, the door frame strip may have a molded into the side cheek grip, the vertex is offset over a predetermined distance from the side cheek in the door-side direction inwards. For a particularly stable design of the door frame strip in combination with the heat insulation layer, it is preferred if the support web of the retaining profile is extended with its inner edge at least up to the level of the above-mentioned grip trough vertex or beyond. The distance of the recessed grip vertex to the support web in the Bautiefenrichtung is approximately in the same area as the distance between the side wall and the inwardly facing end of the support web. This results in a further sandwich structure consisting of the support web of the holding profile, the heat insulation layer and a side edge of the recessed grip.

The Wnkelschenkel running parallel to the side wall can also have a

Groove base of the holding profile form, which together with the already mentioned support web and one of them spaced apart by a groove width, visible angle leg forms a receiving groove which is open inwardly in the door side direction. In the installed position of the visible side Wnkelschenkel the receiving groove overlaps the side edge of the

Plate element, wherein the material thickness of the plate member substantially corresponds to the groove width of the receiving groove and this can additionally be glued therein before the foaming process.

Serving as a groove base Wnkelschenkel and the visible angle leg can together with the side cheek in cross-section converge in a common node. This results in spite of missing visual side of the

Door frame strip a particularly rigid component geometry of the door frame strip, which is particularly important in terms of a deformation-free foaming.

By taking place in the foaming force introduction into the common node forces can be transferred into the star-shaped converging side cheek, Wnkelschenkel and visual side Wnkelschenkel, without causing deformations here.

The plate member may have a front edge, which is visible to the customer in the direction of view. The front edge may be in a special design variant in the

Bautiefenrichtung be offset by a Versatzmaß against the abutting edge of the door frame strip. This results in the viewing direction of the customer a visual shadow, in which the door frame strip disappears protected.

The front side set back support bar of the holding profile can be extended with an angled forward inner angle leg. This can form together with the support web and the outer Wnkelschenkel a front open receiving groove in which the support web acts as a groove bottom. In this frontally open receiving groove an angled edge edge of the plate element can be used around a front edge. The groove width of the receiving groove is dimensioned so that in the Vorrahmenierung of the plate element in the door frame strips a only

slight play in the door side direction.

In addition, the above-mentioned inner Wnkelschenkel can pass at an inner abutment edge in a second support web, with which the plate member in combination state of construction is in plant. Depending on the groove height of the receiving groove open at the front, only the support web which is located in the door side direction may possibly serve as a support base for the plate element, while the front-side receiving groove serves for centering in the door side direction. The inner abutment edge between the inner angle leg and the inner receiving groove may be upstream in a design variant in the Bautiefenrichtung by a Versatzmaß relative to the outer edge abutment. The offset dimension may preferably correspond approximately to the material thickness of the plate element, whereby the outer abutting edge can be flush with the viewing side of the plate element, flush with the surface via a viewing joint.

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

Show it:

1 is a partial exploded view of an upper corner region of the refrigerator door according to the first embodiment;

2 is an enlarged sectional view of the refrigerator door along the sectional plane l-l of FIG. 1.

Figs. 3 and 4 are views corresponding to Fig. 2 different embodiments. In Fig. 1 is a simplified schematic representation of a fragmentary one

Refrigeration appliance door shown, which is constructed mirror-symmetrically to a central axis of symmetry. The refrigerator door has in a conventional manner a

Plastic inner lining 1 with projecting spars 3 on. The inner lining 1 is provided at its free edges 5 with a magnetic seal, not shown, which is insertable in a receptacle 6 of the inner lining 1. Adjacent to the inner lining 1 is a heat insulation 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. The outer panel 8 is constructed in several parts according to FIG. 1 and comprises a, the door front largely engaging plate member, which in Fig. 1 is a plate assembly consisting of a rigid support plate 10 and a visible decorative plate 1 1. The in the

Installation position vertical side edges 13 of the plate assembly 9 are supported according to FIG. 1 in a holding profile of the side door frame strips 17. The door frame strips 17 are according to the invention z. B. aluminum extruded rails with consistently constant profile. In FIG. 1, the holding profile 15 is arranged directly in the front corner region 16 of the door frame strips 17. Starting from the holding profile 15 is immediately followed by a narrow door side cheek 19 in the depth direction y to the rear, the

foam-tight with the free edges 5 of the inner lining 1 is connected. The

Side cheek 19 is arranged in alignment with the depth direction to the rear and has an obtuse angled intermediate web 20 in the front corner region 16, which is connected to the holding profile 15. In the side wall 19 of the door frame strip 17 is formed in accordance with FIG. 1, an approximately triangular profiled continuous recessed grip 21 whose vertex S is offset over a distance a from the side wall 19 inwardly.

The refrigerator door is in the assembly position both at its upper edge (Fig. 1) and at its lower edge, not shown, by a horizontally extending

Cover element 23 covered. In the closing element, a hole-like receptacle 18 is provided, which serves to support the door on the refrigerator housing.

According to FIGS. 1 and 2, the holding profile 15 of the door frame strip 17 is formed by a receiving groove which is open inwardly in the device side direction x. The receiving groove has an outer angle leg 31, which extends plane-parallel to the side wall 19 together with the intermediate web 20 and the side wall 19 defines a gap 22. In the intermediate space 22, the heat insulation layer 7 is filled in the door installation position.

To form the receiving groove 2, the Wnkelschenkel 31 is extended in Fig. 2 with a support web 34 which is angled inward in the door side direction x. A further, visible side Wnkelschenkel 25 is formed opposite to a groove width b thereof, which in FIG. 1 or 2, the side edge 13 of the

Plate element 9 overlaps. As is apparent from Fig. 2, run the intermediate web 20, serving as a groove base angle web 31 and the view side Wnkelsteg 25 in a common node K together, resulting in during the foaming an advantageous

Force distribution between the side wall 19, the Wnkelschenkel 31 and the visible Wnkelschenkel 25 sets. For further stiffening of the refrigerator door according to FIG. 2, the support web 34, starting from the side wall 19, extended by a Längemaß d inwardly, which projects beyond a distance difference a the distance a of the recessed grip vertex S. This results, together with the interposed heat insulation layer 7, an additional sandwich structure section in the region of the holding profile 15, which further supports the rigidity of the refrigerator door.

In Fig. 3, a refrigerator door is shown in a further embodiment, the retaining profile 15 is not formed by a receiving groove, but by a front-side open recess. The return of the retaining profile is limited by the angle leg 31 and by the support web 34. The overall height c of Wnkelschenkels 31 is approximately identical to the material thickness of the plate member 9, resulting in a flush finish between the front abutting edge 33 of the door frame strip and the visible side of the plate element 9 results. Otherwise, the structure and the

Geometry of the refrigerator door identical to the variant shown in Fig. 2.

4, the holding profile is formed as a front-side receiving groove in a further embodiment. In the front open receiving groove of the holding profile, an edge portion 24 of the plate member 9 is inserted. This is angled to the front edge 25 to the rear. In order to form the receiving groove, the support web 34 already shown in the preceding figures is extended with an inner angle limb 26 angled in the opposite direction to the outer knuckle leg 31. The groove width b between two Wnkelschenkeln 26, 31 is slightly larger than the material thickness of the plate element 9 dimensioned. In addition, at a inner abutting edge 39 of the inner Wnkelschenkels 26 a right angled inwardly second closes

Support web 40, with which the plate member 9 is in abutment. 4, the inner abutting edge 39 of the inner Wnkelschenkels 26 in the depth direction y by an offset m ^ with respect to the outer abutting edge 33 of the door frame strip 17th

upstream. The offset m ^ can preferably be chosen so that the side edge 13 from the groove bottom, that is the support web 34, is spaced apart and only on the inner support bar 40 rests. The receiving groove therefore forms an acting in the door side direction x centering, while the inner support web 40 serves as a depth stop when assembling the plate member 9 with the door frame strips 17. The

Plate element 9 may preferably be adhesively bonded to the inner support web 40 via an adhesive bond before the foaming process. By that around the

Offset dimension rrn recessed visible side 27 of the door frame strip 17 also gives an impression of a frameless refrigerator door.
