Description

Refrigerating appliance, in particular household refrigerating appliance

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

Such a two-door refrigeration device can be embodied, for example, as a fridge / freezer combination with a lower and an upper appliance door, each of which closes separate refrigerated spaces. From DE 10 2009 027 891 A1 a generic two-door refrigeration device is known, which has at least two device doors arranged one above the other in the device vertical direction. In addition, a control panel is provided on an upper door closure strip of the lower door, wearing the control and display elements. The upper

Door closure strip delimits a cavity of the upper appliance door filled with heat insulation foam. When the appliance doors are closed, the control panel of the upper appliance door is therefore covered by the lower appliance door. Thus, with closed doors neither information about operating parameters can be viewed, nor is it possible to actuate the controls. The object of the invention is to provide a refrigeration device, in which an ergonomically favorable and comfortable operation of the refrigerator is possible.

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

Further developments of the invention are disclosed in the dependent claims.

The refrigeration device according to the invention has at least two device doors arranged one above the other in the device vertical direction, with each of which cooling chambers of the

Refrigeration device are closed. In order to achieve a clear operation of the refrigeration device, the operating and display elements are no longer in the upper

Door trim strip of the lower door, but rather at the upper end of the lower door, in particular on the front of the device lower door. Preferably, therefore, both the display and the operation is immediate allows the front of the device, even with closed doors. In this way, a particularly convenient and ergonomic operation of the refrigerator is ensured from above at the optimum height.

Preferably, the control and display elements can be combined in a common control panel or control bar. The control panel, together with a door outer wall, can form the front panel of the lower unit door. In addition, the

Control panel be designed with only a small height and extend approximately strip-shaped horizontally in the device side direction. The two stacked in the vertical direction device doors are spaced apart by a separating gap. The separating gap ensures that the paths of movement of the laterally hinged doors do not overlap. Each of the appliance doors can each close a separate refrigerator compartment. The lower door can in a conventional manner a peripheral peripheral

Have narrow side of the door, which merges in the Bautiefenrichtung each edge edges in the, the refrigerator compartment bounding door inside and in the front panel. At the upwardly facing, horizontal door narrow side, an upper door closure strip can be provided. This limits together with a lower door closure strip filled with heat insulating foam cavity of the lower door.

The appliance door of a refrigeration appliance can typically be realized as a hollow body which is filled with a heat insulating foam. The hollow body may consist of a front door outer wall formed for example of stainless steel sheet and a

Door inner wall be constructed, which is for example a deep-drawn plastic board. In between, the space filled with Wärmeisolierschaum cavity is limited. The

Door outer wall may have in the device side direction angled profile strips, which are foam-tight connected to the door inner wall. The cavity of the appliance door filled with heat insulating foam is also delimited at the lower and at the upper edge of the door with a lower and an upper door closing strip.

In one embodiment variant, the control panel can be integrated in the same material and in one piece directly in the upper door closure strip of the lower appliance door. From a manufacturing point of view, however, it is preferred if the control panel and the

Door closure strip from each other are separate components. Preferably, the control panel may be part of a control electronics housing. The control electronics housing may be detachably mounted on the outer side of the door closure strip. In this way, in a first manufacturing step, the appliance door cavity with the aid of

Door closure strips, but still without control electronics housing, initially closed foam-tight. Subsequently, in a foaming process, the cavity can be filled with heat insulating foam. Only in a further manufacturing step, the control electronics housing can then be mounted on the door closure strip of the already completed appliance door.

The upper door seal strip of the lower door may have an exposed top surface in which a recessed mounting recess is provided. In the mounting recess, the control electronics housing can be used.

Preferably, the upper door closure strip in cross-section may be designed in approximately step-shaped, with a forward open in the Bautiefenrichtung

Mounting recess. The mounting recess may be defined by a mounting base and by side walls, which merge at a transition edge in the exposed top of the door seal strip. The control electronics housing can be used contour-adapted in the mounting recess. This means that preferably the overall height and depth of the

Mounting recess corresponds to the housing height and the housing depth. In this case, the housing top can be substantially flush with the above-mentioned visible surface of the door closure strip. Accordingly, the

Housing front wall essentially flush with the front of the device. The housing cover wall and the housing front wall are characterized by, in the

Control electronics housing formed edge edge of each other locally separated. The control panel is provided here alone on the housing front wall. The control electronics housing may be spaced by lateral offset dimensions of the side, upper door door corners of the lower door, in which the

Narrow sides of the door converge. With regard to a door stop change, it is advantageous if the control electronics housing with respect to a vertical device Central axis is arranged symmetrically. This means that preferably also the two offset dimensions can be identical. In the device side direction laterally outside of the control electronics housing, the front upper peripheral edge of the lower door can be formed directly by the upper door closing strip. In contrast, the peripheral edge in the central region can no longer be formed by the upper door closure strip, but by the control electronics housing itself.

The control electronics housing can via any form-fitting and / or

Frictional connections are in particular detachably mounted on the door closure strip. By way of example, screws or screws can be attached to the control electronics housing

Be provided locking elements, which can be brought with corresponding mating contours in the door closure strip in screw or latching connection.

In an alternative embodiment, the control electronics housing, the

Cover the door sealing strip substantially completely protected from view. In this case, therefore, in contrast to the previous embodiment, the door closure strip is provided without upwardly exposed visible surface. Rather, the

Door closure strip on its top a mounting surface on, the depth in the

Essentially corresponds to the depth of the door narrow side. In addition, the depth of the control electronics housing can extend over the entire depth of the door narrow side. Overall, therefore, results in a door that is extended edge up with the control electronics housing.

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.

Show it: Figure 1 is a front view of a fridge freezer with two superposed cooling chambers, which can be closed with separate appliance doors.

2 is an enlarged perspective sectional view along the

Sectional plane l-l of Fig. 1;

Fig. 3 is a sectional view taken along the sectional plane II-II of Fig. 1; and

4 and 5 are views corresponding to FIG. 3 of further

Embodiments.

In Fig. 1 is shown as a refrigerator, a refrigerator / freezer combination, in which a lower door 1 and a top door 3 each separate separate refrigerated spaces. The two appliance doors 1, 3 are each laterally about a vertical

Swivel axis 5 articulated and spaced apart in the device vertical direction z via a slight separating gap 7. Each of the appliance doors 1, 3 is constructed as a hollow body whose cavity 9 (FIG. 2) is filled during a foaming process with a heat insulating foam (not shown). The cavity 9 is limited according to the following figures 2 to 5 of a device front forming the door outer wall 13 and a door inner wall 14. At the respective Tuerber- and -oberseiten the cavity 9 is closed foam-tight with each other by lower and upper door closure strips 17.

As is further apparent from Fig. 1, a horizontally elongated in the device side direction x control electronics housing 15 is provided on the door top of the lower door 1. The housing 15 is spaced from the lateral upper corner doors 10 of the lower door 1 with approximately equally large offset dimensions a, b and arranged symmetrically to a vertical center axis M of the door 1. In addition, the housing 15 in an edge-upwardly open recess 20 (Fig. 3) of z. B. made of stainless steel sheet door front wall 13 edged. In the control electronics housing 15 dash-dotted line electronics components 12 and each control and display elements 16, 18 are provided for the operation of the refrigerator. The control electronics housing 15 is exposed device front side with a housing front wall 37, a user-side control panel or control bar forms in the display elements 18, such as seven-segment displays or other visual displays, as well

Control elements 16 are summarized. The narrow control strip extends horizontally in the device side direction x at the upper edge of the lower door 1. According to FIG. 2, lower and upper door seal strips 17 are provided on the horizontal door narrow sides 19 of the appliance doors 1, 3 facing each other. The facing door narrow sides 19 go according to FIG. 2 at the edge edges 21 in each case in the door inner wall 14 and in the door outer wall 13 via. In the

Device side direction x laterally outside of the control electronics housing 15, these marginal edges 21 are formed directly by the door closure strips 17 (Fig. 2).

In contrast, in the lower door 1 in the depth direction y front edge 21 in the middle region is no longer formed by the upper door closing strip 17, but by the control electronics housing 15 itself (Fig. 3). The

Control electronics housing 15 is designed in the figures as a rectangular closed hollow profile, which encloses the space for the electronic components 12. Alternatively, the control electronics housing 15 can also be designed as an open angle profile or as a flat profile, which encloses the installation space for the electronic components 12 together with the door closure strip 17. The upper door narrow side 19 of the lower appliance door 1 will be described in more detail below: Thus, the upper door narrow side 19 by means of the upper

Door closure strip 17 and the control electronics housing 15 are formed, which form a detachable two-piece unit. As is apparent from Fig. 3, the upper door closing strip 17 of the lower door 1 is angled forward stepwise to form a mounting recess 23. In the mounting recess 23 of the upper door trim strip 17 of the lower door 1, the control electronics housing 15 is inserted. The mounting recess 23 is bounded by a vertical side wall 25 and by a horizontal mounting base 27. The side wall 25 is shown in FIG. 3 at a transition edge 29 in an exposed upward visible surface 31 of the upper door trim strip 17 of the lower door 1 via. In contrast, the

Mounting bottom 27 in the Bautiefenrichtung y forward in solid connection with an angled edge web 33 of the example formed of stainless steel

Door outer wall 13 of the lower appliance door 1. The depth shown in FIG. 3 t of Mounting base 27 and the height h of the side wall 25 are dimensioned such that the top wall 35 and the front 37 of the control electronics housing 15 approximately flush, ie continuously, to form transition joints with the visible surface 31 of the door seal strip 17 and the door outer wall 13 of lower appliance door 1 are aligned.

As already mentioned, the operating elements 16 and the display elements 18 are all arranged in the housing front side 37 of the control electronics housing 15, which forms the user-side control panel of the refrigeration device. The control panel is bounded at the top by the peripheral edge 21, at which the front panel 13 merges into the upper door narrow side 19. Even with closed doors 1, 3, therefore, the control panel is readily visible and operable.

The control electronics housing 15 shown in FIG. 3 is releasably supported by latching elements 39 on corresponding counter-contours of the side wall 25 and the mounting base 27 of the mounting recess 23.

Alternatively or in addition to the latching connection shown in FIG. 3, the control electronics housing 15 can also have a direction indicated in FIG. 4

Screw 41 is mounted, in which a lower housing of the

Control electronics housing 15 via a bolt, not shown, with a Schraubdom 43 of the upper door trim strip 17 of the lower door 1, is screwed. For this purpose, the screw dome 43 is provided in the mounting base 27 of the mounting recess 23. In addition, in FIG. 4, those shown in FIG

Locking elements 39 of the control electronics housing 15 with corresponding

Contour contours on the vertical side wall 25 and on the mounting base 27 of

Mounting recess 23 be in locking engagement.

5, a further embodiment is shown, in which the control electronics housing 15 is connected via snap-in connections 39 with the upper door closing strip 17 of the lower door 1. Unlike the previous ones

Embodiments, the control electronics housing 15 extends over the entire overall depth of the upper narrow side of the door 19. The top of the door closure strip 17 therefore serves - not omitting the visible surface 31 - not only partially, as in FIGS. 3 and 4, but rather completely as a mounting surface on which the control electronics housing 15 can be mounted. As a result, the door closure strip 17 is completely covered by the control electronics housing 15 at the top. The upper narrow side of the door 19 of the lower door 1 is therefore completely formed by the upwardly exposed housing top wall 35.
