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 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 these two lateral vertical door frame strips, between which a large-area decorative plate is provided as a separate component. 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.

In DE 198 56 093 A1, the two above-mentioned lateral door frame strips as a holding profile on each other in the door side direction facing U-shaped grooves, in which the side edges of the decorative plate are used. The assembly of the outer lining takes place prior to the foaming process assembly technology consuming, in which the decorative plate is inserted from above / below in approximately plane-parallel to the inner lining in the grooves. The decorative panel is prepositioned with little play within the grooves. The movement play is dimensioned so that on the one hand the decorative plate can be inserted without jamming into the receiving grooves and on the other hand a foam-tight connection between the side edges of the decorative plate and the door frame strips is made. In assembly are the

Side edges of the decorative plate on the front overlapped by groove legs of the receiving groove, resulting in stepped between the decorative plate and the door frame strips Transitions result. Design variants of the appliance door with a completely planar door front are therefore not possible in 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 also different design variants of the 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 cladding 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, vertical door frame strips have according to the characterizing part of claim 1 in the door Bautiefenrichtung undercut-free holding profile, in which the plate element can be used in the Bautiefenrichtung. According to the invention, the plate element is therefore no longer technically complicated to insert plane-parallel to the inner lining of the top / bottom in the grooves of the door frame strips, but they can be placed process technology easily in the holding profile. Depending on its material thickness, the plate element inserted in the retaining profile of the door frame strips can be flush-formed with the adjacent visible sides of the door frame strips or can be preceded or set back in the depth direction Be arranged door frame strips. Thus, all design variants are open with the holding profile according to the invention.

The undercut-free retaining profile may have in one embodiment, a front-side open, step-like recess. This can have over the visible side of the door frame strips recessed support webs on the in the

Assembly state, the plate element rests. The support web can be integrated as a separate component of the door frame strips or in the door frame strips. The door frame strips can be produced, for example, as extruded aluminum parts whose profile remains consistently constant in the longitudinal direction.

In terms of component reduction, it is advantageous if the step-like recess is formed directly in the door frame strips. In this case, the retaining profile may be limited by an angle leg projecting rearward in the depth direction and by an adjoining, angled support web. The rearwardly projecting angle leg can pass over an abutting edge in one piece in the visible side of the door frame strip. The protruding back Wnkelschenkel the step-like recess may preferably be arranged in the door side direction outside the Plattenelement- side edges, so that the side edges of the door frame strips are facing each other via a slight parting line. The Wnkelschenkel the door frame strips thus form a frame-like enclosure for the plate element.

In the design of the retaining profile according to the invention, if appropriate, the side edges of the plate element can be visibly exposed on the front side. At the side edges of the plate element can thereby trigger the outside door frame strips. These may preferably be slightly spaced from one another via a visual joint which can be designed as a design feature.

We already mentioned above, is a flush transition between the

Plate element and the door frame strips readily possible. For this purpose, it is necessary that the step height or height of the recess is approximately identical to the material thickness of the plate member. In a further embodiment variant, the retaining profile may have a receiving groove, which is designed to be open in the direction of the depth direction to the front. The receiving groove can basically be made identical to the above-mentioned return. The above-mentioned, rearwardly projecting angle leg and the right adjoining support web here each form a groove side wall and a

Groove base. The support web acting as a groove bottom can be extended by a second wrench leg, which is formed in the opposite direction to the first angle limb and forms the second groove wall, which is spaced from the first worm leg over a predetermined groove width. The first Wnkelschenkel is therefore in the door side direction outside, while the second Wnkelschenkel lies inside. The groove width may preferably be determined by the material thickness of the edge portion of the groove to be inserted into the receiving groove

Align plate element. In order to achieve a good pre-centering of the plate during assembly of the outer lining, however, a possible backlash-free mounting of the plate element in the receiving groove is advantageous. The edge section of the

Plate element may preferably around a plate element front edge in the

Bautiefenrichtung be angled backwards. Depending on the length of the edge portion may be supported with its side edge directly on the groove bottom. Alternatively or additionally, the plate element may be supported on an upper edge of the inner Wnkelschenkels, while optionally the side edge of the plate member is spaced from the groove bottom of the receiving groove. In such a case, the

To increase support base for the plate member, the inner Wnkelschenkel of the holding profile can pass at an inner abutting edge in an inner support web, which can be made much wider compared to the aforementioned first support web.

In a further embodiment, the inner abutting edge between the inner Wnkelschenkel and the inner support web in the Bautiefenrichtung to a

Offset dimension be upstream of the outer abutting edge. The outer abutting edge with the subsequent visible side of the door frame strip is therefore offset towards the front (ie visible side of the plate member) to the rear and therefore lies in the direction of a user in the visual shadow of the plate element, resulting in the impression of a frameless refrigerator door. This impression can also be reinforced if the retaining profile is located directly in the front corner region of the door frame strip, that is to say directly at the transition to the side cheek of the door frame strip. According to a further embodiment, the front edge of the plate element may be upstream in the depth direction by an offset dimension relative to the outer abutting edge, whereby the impression of a frameless refrigerator door is further enhanced.

As mentioned above, the receiving groove at the transition to the visible side of

Door frame strip an outer edge and on the inside offset angle leg on an inner joint edge, which optionally passes into the second large-scale and inner support web. In a further embodiment, the inner abutting edge between the inner Wnkelschenkel and the large-scale inner

Support web to be reset by a Versatzmaß against the outer edge. The offset dimension may preferably correspond to the material thickness of the plate element. In this case, in assembly position, the plate element flush below

Pass the intermediate layer of a parting line into the visible side of the door frame leg.

In a further embodiment, the plate element may have an edge portion, which projects beyond an excess edge in the lateral direction with respect to a further edge portion of the plate element. This results in a lateral projection in the side edge of the plate element. The lateral projection of the plate member may project beyond the above-mentioned outer joint edge on the retaining profile, whereby it is no longer visible from the outside. Optionally, the lateral projection of the

Plate element overhang the entire front side of the visible side of the door frame strip, which also gives the impression of a frameless refrigerator door can arise. The remaining, recessed edge portion of the plate member may in contrast be immersed in the recess of the retaining profile and secured therein.

As mentioned above, the retaining profile can be directly in the front corner of the

Door frame strip be arranged, which gives the impression of a frameless

Refrigeration appliance door results. In addition, in this case, the holding profile can be extremely rigidly connected to the door frame strip, in comparison to one with a larger

Side offset to the front corner area provided retaining profile. When arranged in the front corner holding profile, the side cheek can connect directly to the holding profile via an obtuse angled gutter. Of the

Gutter of the side cheek goes over the above-mentioned outer edge in the Angle leg of the holding profile over. To further increase the dimensional stability of the door, a space bounded by the angle leg of the holding profile and by the side wall spaced therefrom can be filled with the heat insulation layer. This results in the corner of the door a three-layer composite structure consisting of the outer side wall, possibly with the gutter, and the inner Wnkelschenkel of the holding profile.

In another embodiment, in the first or outer Wnkelschenkel of the holding profile in the device side direction inwardly open receiving groove may be formed. The receiving groove may have a groove width which corresponds approximately to a material thickness of a second, optionally thinner-walled decorative element. The

Holding profile therefore has with the receiving groove in the outer Wnkelschenkel and the front open recess two decorative element recordings that are alternatively usable depending on the selected decorative element.

In particular, in a thin-walled design of the door frame strips, the undercut-free holding profile according to the invention can be due to geometric

Conditions lead to a reduced component stiffness of the door frame strip. Due to the special geometric design of the door frame profile, the

be counteracted. Thus, the rear cheeks projecting side cheeks of the door frame strips can pass directly into the holding profile. The side cheek of the respective door frame strip may also have in the front corner of an obtuse angled gutter, which is connected to the retaining profile, so that there is a gap between the side cheek and the angle leg. The space left in front of the foaming process is during the

Foaming process filled with the heat insulating layer. This results in the front corner of the refrigerator door despite low cost of materials and despite holding profile with reduced stiffness an extremely dimensionally stable sandwich structure consisting of the outer side cheek, the heat insulation layer and the Wnkelschenkel of the holding profile.

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

4 and 5 each further embodiments of the invention in views

in accordance with FIGS. 2 and 3; and Fig. 6 and 7, another embodiment with a holding profile, the recordings for

Having decorative elements of different thicknesses.

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 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 insulating layer 7 connects the inner lining 1 with a

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 largely occupies the front of the door and which in FIG. 1 is a plate composite consisting of a rigid support plate 10 and a visible decorative plate 11. The vertical in mounting position side edges 13 of the plate assembly 9 are supported according to FIG. 1 in a holding section 15 of the side door frame strips 17. The door frame strips 17 are according to the invention, for example, aluminum extruded rails with consistently constant profile. In Fig. 1, the holding profile 15 is directly in the front

Corner 16 of the door frame rails 17 arranged. From the holding section 15 is immediate an aligned in the depth direction y aligned narrow door side wall 19 in the depth direction y angled backwards, 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 assembly position both at its upper edge (Fig. 1) and at its lower edge, not shown, by a horizontally extending end member 23, for example made of plastic injection molding or of metallic

Material, such as aluminum, can be made. The outer contour of the respective end elements 23 is approximately adapted to the contour of the refrigerator door at the upper edge and the lower edge, wherein the inner lining 1 and the

Door frame strips 17 and the plate assembly 19 is encompassed by the respective end member 23. The end elements 23 also have hole-like receptacles 18, which serve to support the door on the refrigerator housing. 2, the plate assembly 9 and the holding section 15 of the door frame strips 17 is shown enlarged. Accordingly, the door frame strips 17 for receiving the side edges 13 of the plate assembly 9 on their sides facing each other on a front side open, step-like recess, which is undercut in the door depth direction y. In the case before the foaming process

Assembly of the outer lining 1, therefore, the plate assembly 9 can be easily inserted in the Bautiefenrichtung y in the front open recess of the retaining profile 15. The recess is formed according to FIGS. 1 and 2 directly on the front door corner region 16, so that only a very narrow view side 27 of the door frame bar 17 forward freely for the user is visible. The visible to the front view side 27 of the door frame strip 17 is in FIG. 2, a joint edge 33 which merges via an inclined intermediate web 20 in the side cheek 19. At its, the side edge 13 of the plate assembly 9 side facing the outer abutment edge 33 merges into a rearwardly projecting leg angle 31, at which an inwardly angled support web 34 connects. The support web 34 provides a large support base for the plate assembly 9. The plate assembly 9 is, as already mentioned above, formed from the adjacent to the heat insulating foam support plate 10 and the decorative element 1 1, which are firmly connected. As a result of the step-like recess which is open towards the front, a front viewable visible joint 35 between the side edge 13 of the panel assembly 9 and the abutting edge 33 of the door frame strip 17 is exposed as shown in FIG. The height c of the recess is dimensioned so that it corresponds approximately to the material thickness of the plate assembly 9. In this way, the result shown in Figs. 1 and 2 flush transition between the plate assembly 9 and the visible side 27 of the door frame strip 17. This special design is in the line of sight of the user

Door frame strip 17 substantially protected behind the panel assembly 9, so that there is the impression of a frameless refrigerator door.

In Fig. 3, the holding profile 15 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. To form the receiving groove is already mentioned in FIG. 2 support web 34 with a counter to the outer

Wnkelschenkel 31 angled inner angle leg 26 extended. The groove width b between two Wnkelschenkeln 26, 31 is slightly larger than the material thickness of the plate element 9 dimensioned. In addition, adjoins an inner abutting edge 39, a right angle inwardly angled second support web 40, with which the

Plate element 9 with its underside in abutment. According to FIG. 3, the inner abutting edge 39 of the inner leg 26 is in the depth direction y about

Offset dimension rrn with respect to the outer abutting edge 33 of the door frame strip 17th

upstream. The offset dimension rrn can preferably be selected such that the side edge 13 is spaced from the groove base, that is to say the support web 34, of the receiving groove and lies only on the inner support web 40. The receiving groove therefore forms an acting in the door direction x centering, while the inner support web 40 as

Depth stop when assembling the plate member 9 with the door frame strips 17 is used. The plate element 9 may preferably be adhesively bonded to the inner support web 40 via an adhesive bond. By the metric offset by the m ^ reset visible side 27 of the door frame strip 17 results in the direction of the user also the impression of a frameless refrigerator door.

In the embodiment of Fig. 4, the holding profile is also formed with a front open receiving groove. In contrast to FIG. 3, in FIG. 4, the visible side 27 of Door frame strip 17 is not offset to the rear, but formed flush with the plate element 9, with the interposition of a visual joint 35, as shown in Fig. 2 already. In contrast to FIG. 3, therefore, in FIG. 4, the inner abutment edge 39 between the second angle leg 26 and the inner support bar 40 is reset by an offset m ₃ with respect to the outer abutment edge 33. The offset m ₃ corresponds approximately to the thickness of the plate element. 9

In Fig. 5, the holding profile 15 of the door frame strip 17 is constructed approximately as shown in FIG. 1 and FIG. 2. In contrast to FIGS. 1 and 2, however, in FIG. 5, an edge section 14 of the decorative element 1 1 in the door side direction x projects beyond the lower support plate 10 with a projection a. The material thickness of the support plate 10 is dimensioned such that it terminates approximately flush with the visible side 27 of the door frame strip 17. As a result, the decorative element 11, with its edge section 14, project beyond the front visible side 27 of the door frame strip 17 in a protected manner. The supernatant a is dimensioned so that the door frame strip 17 is arranged in the viewing direction of the user completely visible behind the edge portion 14 of the decorative element 1 1.

6 and 7, a further embodiment is shown, wherein the holding profile shown therein also have an outer side in the device direction Wnkelschenkel 31, which merges into an angled support web 34. In contrast to the preceding figures is in the aligned in the depth direction y y

Wnkelschenkel 31 introduced an additional receiving groove 43. The groove width of the receiving groove is adapted so that a comparatively thin-walled decorative element 44 can be used. Alternatively, instead of the thin-walled decorative element 44 according to FIG. 7, a thick-walled decorative element may be used whose

Material thickness substantially the height c of the return corresponds. In FIG. 7, therefore, the receiving groove 43 remains inoperative and this is covered by the side edge 13 of the thick-walled decorative element 9. LIST OF REFERENCE NUMBERS
