According to the invention, the door border strip (17) has a recessed grip (19) and is made of two parts consisting of a dimensionally stable main part (21) and a decorative panel (23) that at least partly covers a visible user-side inner face of the recessed grip (19).

Description

Refrigerating appliance, in particular household refrigerating appliance

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

In household refrigerators, the appliance door is realized as a hollow body which is filled with a Wärmeisolierschaum. The door outer wall visible from the front can be a stainless steel sheet with a small wall thickness for design reasons. The door inner wall connected thereto can be made of a thermoformed plastic board.

In a generic refrigeration appliance, the appliance door has a cavity filled with Wärmeisolierschaum, which is bounded by a door inner wall and a, the door front-forming door outer wall. The edge of the cavity is closed by at least one door closure strip. In order to avoid any irregularities, such as bulges, in the inner and outer walls of the door and the door closing strip during the foaming process, these are dimensionally stable despite their thinner material thickness. The door closure strip can be formed, for example, from a plastic material of high inherent rigidity. Its visible side can also be elaborately painted to ensure a visually appealing appearance of the door. In addition, the appliance door on an operating handle.

From DE 186 64 17 U a handle for fold-out doors to household appliances is known. The handle is sunk in the door level in the region of a door hinge opposite door edge or retracted inside the door.

The object of the invention is to provide a refrigeration device, in particular household refrigeration appliance, in which the appliance door is constructed in a simple and visually appealing manner. The object is solved by the features of claim 1. Preferred embodiments of the invention are disclosed in the subclaims. In the refrigeration appliance according to the invention, the appliance door has a door inner wall facing the refrigerator compartment and an outer door wall which forms the door front and delimits a cavity filled with heat insulating foam. The cavity is closed at the edge of at least one door closure strip. According to the invention the door closure strip in the sense of a component reduction on a recessed grip. In addition, the door closure strip with the integrated recessed grip is constructed in two parts from a dimensionally stable base body and a decorative cover which at least partially covers a user-visible inner side of the recessed grip. By integrating the recessed grip directly in the door closure strip, installation of a separate grip piece on the appliance door can be omitted. Likewise, elaborate sheet metal forming to form a handle recess in the outer door panel can be avoided. The door closure strip can preferably be produced, for example, as a plastic injection-molded part, on which the recessed grip is injection-molded. The door closure strip can therefore be made of a material of high inherent rigidity, but reduced surface quality. The user-visible areas of the recessed grip can be covered by means of the trim to achieve a visually pleasing appearance of the recessed grip despite the reduced surface quality.

A refrigeration device is understood in particular to mean a domestic refrigeration appliance, that is to say a refrigeration appliance which is used for household management or possibly also in the gastronomy sector, and in particular serves to store food and / or beverages in customary quantities at specific temperatures, such as, for example, a refrigerator. a freezer, a fridge-freezer or a wine storage cabinet. In particular, the door outer wall of the door can be made of a stainless steel sheet. The door outer wall may have laterally angled profile strips, which are connected to the inner door wall. The top and bottom of the door are each closed by separate door closure strips. Preferably, the main body of the two-part door seal strip can be made of a plastic material, which also complex handle recess geometries can be designed in a simple manner. By way of example, the door closure strip can have an outer door closure surface, which is aligned essentially at right angles to the door outer and inner walls. The recessed grip can be recessed in the door frame. This can be roughly be formed shell-shaped with a trough bottom, from which a front side edge in the Bautiefenrichtung and a rear side edge is pulled up. The front side edge forms a handle bar, which can be grasped manually by the user. In contrast, the rear side wall in the depth direction forms a recess-rear wall, which can be aligned approximately parallel to the door front of the door. Depending on the configuration of the door closure strip, the recessed back wall that is recessed in the depth direction with respect to the door front can be particularly obvious to the user. Preferably, therefore, the trim cover specifically cover the trough back wall. As a result, the overall appearance of the door front can be increased in a simple manner despite possibly reduced surface quality of the body. Preferably, the decorative blind can be glued as an insert with the inside of the grip. For this purpose, the main body of the door closure strip may have a trim bed, which is set back in particular by the material thickness of the trim panel. After the decorative panel has been inserted into the trim panel bed, there is thus a substantially flush, ie stepless transition, between the decorative panel and the adjacent surface areas of the recessed grip.

The gripping strip forming the front side edge of the recessed grip can merge at a front transition edge in an edge web. This at least partially defines a front-side engagement opening of the recessed grip. In the further course forward can connect to the edge web of the recessed grip a connecting flange with which the door outer wall is connected. In contrast, the rear side wall flank, which defines the recess rear wall in the depth direction, can transition at a rear transition edge into the above-mentioned right-angled door closure surface or base plate of the door closure strip. The door closing surface is also connected via a connecting flange on the door inner wall of the appliance door. With such a structure, the overall height of the front side edge of the recessed grip can be less by a height difference than the height of the rear side edge of the recessed grip, whereby a front accessible engagement region is realized. To increase the feel, the front side flank of the recessed grip, together with the door outer wall, can form a stiff double-wall structure, with interposed heat insulating foam. The grip behind the user by the user handle is thus carried out a total of three layers, with the door outer wall, the intermediate Wärmeisolierschaum and the front side edge of the door closure strip. The grip recess integrated in the door closure strip can preferably be mirror-symmetrical to a vertical center axis. Extensive conversion measures during a stop change can thus be avoided. In addition, the handle length of the handle recess in the device side direction substantially correspond to the door width of the device. The cup-shaped recessed grip can be completed in the device side direction in each case by lateral end walls, which are integrated in the base body of the door closure strip. In the installation position, the trim panel can be positioned so that it extends substantially over the entire handle length and / or occupies the entire height of the rear side edge, which forms the trough rear wall in the vertical direction. In the above-specified geometry of the recessed grip results in the Bautiefenrichtung behind the handle an undercut, which casts shadows and therefore not readily visible from the outside by the user. Preferably, the decorative cover extends in the vertical direction into the undercut of the recessed grip, whereby the surface of the main body of the door closure strip is largely visible within the recessed grip.

In a particular embodiment, the refrigeration device has separate and stacked cooling chambers, each of which can be closed with a separate appliance door. Preferably, the recessed handle set forth above may be mirror-symmetrical in each case in the door end strips facing each other in the vertical direction. For a component reduction, it is sufficient if two identical door closure strips are kept, which are each rotated by 180 ° mounted on the envelope at the upper and lower edges of the device doors facing each other. This results in a comparatively large engagement opening at the transition area between the appliance doors, which is defined in each case by the edge web of the lower and the upper door closure strip.

The advantageous embodiments and / or further developments of the invention explained above and / or reproduced in the dependent claims can be used individually or else in any desired combination with one another, for example in the case of clear dependencies or incompatible alternatives. The invention and its advantageous embodiments and further developments and advantages thereof are explained in more detail below with reference to drawings.

1 shows a front view of a refrigerator / freezer combination with two superposed cooling chambers, which can be closed with separate appliance doors;

2 shows in an enlarged sectional view a transition region between the two superimposed device doors. and

Fig. 3 is an enlarged perspective sectional view of the upper door seal strip of the lower door.

In FIG. 1, a refrigerator / freezer combination is shown as a refrigeration appliance, in which an upper appliance door 1 and a lower appliance door 3 respectively close separate cooling chambers. The two appliance doors 1, 3 are each hinged laterally about a vertical pivot axis 5 and spaced apart in the device vertical direction z via a slight separating gap 7. As can be seen from the further figures, each of the appliance doors 1, 3 is constructed as a hollow body whose cavity 9 (FIGS. 2 and 3) is filled with a heat insulating foam 11 during a foaming process. The cavity 11 is bounded in accordance with FIGS. 2 and 3 by a door outer wall 13 forming the appliance front and a door inner wall 15. At the respective TÜberber- and lower edges of the cavity 9 is each foam-tight closed by Türabschlussleisten 17. In FIGS. 1 and 2, a recessed grip 19, which extends in the device side direction x with a handle length I, which is almost the total width of the appliance doors 1, 3, is integrated into the door closing strips 17 facing each other in the vertical direction z. The two door closure strips 17 are in this case designed to be mirror-symmetrical about a horizontal axis of symmetry and about a vertical center axis. In the present case, the two door closing strips 17 are constructed in the same way and each rotated by 180 ° to each other mounted on the envelope in the lower edge of the upper door 1 and the upper edge of the lower door 3. The door outer wall 13 can be produced, for example, from a stainless steel sheet, while the respective door closing strip 17 is invented. According to the two parts of a dimensionally stable base body 21 and a trim panel 23 is constructed. The rigid base body 21 is made of a plastic injection molded part, the plastic material has a high inherent rigidity. As a result, on the one hand, a comparatively complex grip recess geometry in the door closure strip 17 can be realized. On the other hand, the door closing strip 17 is sufficiently dimensionally stable even with reduced material thickness compared with the foaming pressure prevailing in the foaming process. The design of the door closure strips 17 with low material thickness is in view of the only very limited available space in the separating gap 7 of great importance. The geometry of the recessed grip 17 according to the invention is described below on the basis of the upper door closing strip 17 of the lower appliance door 3 according to FIG. 3. The opposite in the device side direction x, not shown corner region is designed mirror-symmetrically. Thus, the recessed grip 19 is cup-shaped with a trough bottom 25, of which in the Bautiefenrichtung y a front side edge 26 and a rear side edge 27 projects upwards. The front side edge 26 forms a handle bar 29 described below. The rear side edge 27 of the recessed grip 19 forms a user-visible from the outside trough-rear wall. The thus designed recessed grip 19 is embedded in a horizontally planar base plate 31 of the base body 21. According to FIG. 3, the base plate 31 of the main body 21 lying in the horizontal plane merges with the transitional edge 33 into the rear side flank 27 of the recessed grip 19. In addition, the thus limited recessed grip 19 in the device side direction x is limited by lateral end walls 35, which are also integrally integrated in one piece and integral with the main body 21 of the door closing strip 17. In contrast to the rear side flank 27, the front side flank 26 projects only above a height h ₂ reduced by a height offset h h relative to the overall height and merges into an edge web 38 at an upper transition edge 37. 3 limits the lower region of an engagement opening 39. As is further apparent from FIGS. 2 and 3, the grip strip 29 formed in this way has a total of three layers, namely with the outer door wall 13, an intermediate foam layer of the thermal insulating foam 1 1 and the front side edge 26 of the recessed grip 19. Both the rear in the depth direction y base plate 31 and the front edge web 38th the door closing strip 17 are foam-tightly connected to the door outer wall 13 and the door inner wall 15 via connecting flanges 41.

Through the engagement opening 39 therethrough, the side wall forming the trough-rear wall 27 is freely visible on the user side. The side edge 27 is therefore covered over the entire surface by the trim 23. Accordingly, an optionally inferior appearing surface of the main body 21 can be laminated in a simple manner. For a secure mounting of the trim panel 23, a trim panel bed 43 may be provided in the side edge 27, which is so set back by a Materialstäke the trim panel 23. The trim panel 23 may be permanently inserted in its decorative bed 43 via a non-illustrated adhesive layer. According to FIG. 2, the ornamental panel 23 glued in this manner extends from the trough bottom 25 to the upper transitional edge 33. The uncovered surface area of the basic body 21 remaining within the recessed grip 19 is therefore arranged essentially in the undercut 28 situated behind the grip strip 29 However, it casts shadows that prevent immediate viewing of the body surface within the recessed grip 19.
