Description

 Door for a household refrigerator with a cover of a display device forming door closure strip and

 Domestic refrigeration appliance with such a door

The invention relates to a door for a household refrigerator, which has a door outer wall and a door inner wall and extending between the door outer wall and the door inner wall door closure strip. The door further includes an electronic display device located in the door. The display device is positioned so that information is displayed in the area of the door closure strip. Furthermore, the invention also relates to a household refrigerator with such a door.

A corresponding domestic refrigerator is known for example from DE 10 201 1 082 790 A1. There, it is provided that a separate door closure strip is formed, which thus closes or covers the door on a narrow edge at the end. This door closure strip is formed there compulsorily stepped. In a lowered area, a housing of a control electronics is arranged above the door closure strip and locked with this door closure strip. This housing is formed separately from the door closure strip and closed in itself. In terms of size, this housing is arranged practically precisely in the lowered area of the door closure strip.

By such a configuration, however, undesirable gaps arise outwardly between the complexly shaped door closure strip and this housing. Due to the geometry of the door seal strip due to manufacturing tolerances and mounting tolerances possibly even magnifications of this column occur. It can thus collect dust or liquids in these columns. In addition, the assembly is complicated with the locking of the housing of the control electronics at several points of the complex shaped door closure strip. It is an object of the present invention to provide both a door for a household refrigerator and a corresponding household refrigeration appliance, in which such gaps can be avoided. This object is achieved by a door and a household refrigerator according to the independent claims.

A door according to the invention for a household refrigerating appliance comprises a door outer wall and a door inner wall arranged separate and spaced therefrom. The separate door outer wall and the door inner wall are connected by a door closure strip which extends between the door outer wall and the door inner wall. The door also includes an electronic display device located in the door. The display device is positioned so that an optical display of information takes place in the area of the door closure strip. This means that the optical signals of the display device in the area of the door closure strip are delivered outside the door. An essential idea of the invention can be seen in that this display device has a cover that covers the electronic components of the display device after door outside. This cover is also formed by the door closure strip itself. It is thus integrated in a single component, namely the door closure strip, the function cover of the display device and it is thus realized in a single component this multifunctionality. Such a configuration avoids unwanted gaps between a door closure strip and a separate display device. In addition, the number of components is reduced and thus reduces assembly costs. The cover is thus virtually integrated into the door closure strip.

The door closure strip thus forms the outermost component on a narrow edge region of the door, which thus visibly shapes the door.

In an advantageous embodiment, the cover is designed as a U-profile. This is advantageous, because then not only a self-level plate is provided, which virtually closes the door only over a plane and covers the electronic components, but over at least three sides has a corresponding function. The lateral penetration of dust or dirt is avoided. In addition, the mechanically stable attachment of such a geometrically specific component is improved. Just then, if this door closure strip by the additional function of the cover of the display device also accurate position to the electronic components must be arranged and must remain stable in position there in order to then send the optical signals through the door closing strip and the cover positionally accurate, this is advantageous.

Preferably, the electronic components are arranged in a receiving space formed by the U-shape. By virtue of such positioning of these electronic components, which is lowered into the U-shape as it were, these are arranged in a more protected manner. In addition, the distance between the electronic components, in particular also light sources of the display device, to a U-bottom of the U-shape and / or to a U-side wall of the U-shape as low as possible, so that light losses and blurred optical representations are at least significantly reduced can.

It is preferably provided that the U-shaped cover has a transverse to the door outer wall and transverse to the door inner wall extending U-bottom through which a display of information. Optical signals are therefore also emitted by electronic components, in particular light sources of the display device and transmitted through this U-bottom, so that they can be perceived outside the door closure strip accordingly by an observer. In particular, it is provided that the U-shaped cover has a U-side wall extending in the direction of the door outer wall and in the direction of the door inner wall, through which information is displayed. Thus, it is not only possible to send optical signals through the U-bottom virtually upwards, but additionally or instead also to transmit optical signals through such a U-sidewall. As a result, depending on the situation, the respectively best possible presentation surface or presentation page for the optical information can be selected and / or greater variety is offered with regard to the comprehensibility of information to be displayed. It is preferably provided that the U-shape is arranged with its opening facing the door outer wall and the door inner wall. The space between the door outer wall and the door inner wall is characterized hood-like closed by this U-shape. It is preferably provided that an arranged between the door outer wall and the door inner wall and this door outer wall and the door inner wall connecting and in cross-sectionally U-shaped connecting part is arranged at least partially in a receiving space formed by the U-shape of the cover. This separate connection part can thus be an internal door closing part. This can be provided when a gap between the door outer wall and the door inner wall is filled with a thermally insulating material, in particular with an insulating foam, and this should not come into direct contact with the display device. Then, this connection part can form the conclusion of this gap and this thermally insulating material can reach a maximum up to this connection part. This connecting part then constitutes, as it were, a partition wall between the thermally insulating material and the display device, in particular the electronic components of the display device. Preferably, this connecting part is connected directly to the door outer wall and the door inner wall.

On the other hand, however, this connecting part can also serve as a carrier or supporting part of the components of the display device.

It is preferably provided that a U-side wall of the U-shape has a receiving slot into which the inner door wall extends. As a result, a mechanically secure and stable connection between the specifically formed in this regard cover and the inner door wall is formed.

It can be provided in an advantageous embodiment that the U-shaped cover formed in the height direction of the door overlaps the door outer wall and the door inner wall each encompassing each other on the outside. This U-profile is therefore arranged with its U-side walls, the respective facing the cover ends of the door inner wall and the door outer wall on the outside embracing.

It can be provided that the cover is connected directly to the door outer wall and / or the door inner wall. For example, a gluing may be provided here. In an advantageous embodiment, it is provided that the cover extends over at least 90 percent of the width, in particular over the entire width, the door outer wall and the door inner wall. As a result, the aforementioned advantages of the gap freedom and the thus protected arrangement against dust entry or liquid entry on the one hand and the component reduction on the other hand are improved.

It can be provided that the cover extends over at least 90 percent of the depth, in particular over the entire depth, between the door outer wall and the door inner wall. Here, the above benefits apply accordingly.

In particular, therefore, the cover is formed as an integral part, which extends over the entire width and the entire depth of this embodiment with the door outer wall and the door inner wall.

In an advantageous embodiment, it is provided that the cover, at least in the region of the optical displays to be carried out, is permeable to light in the spectral range visible to humans. In an advantageous embodiment, it is provided that the cover is formed from a dyed material which, at least from the outside, does not prevent the electronic components from being optically displayed in a state which does not indicate information, in particular avoiding them. This means that this coloration of the cover is designed so that in the generation of optical signals they can be sent through the cover in this area and can be perceived properly by an observer. On the other hand, if no such generation of optical signals, this cover is not fully transparent and the view to the electronic components is at least significantly limited. In particular, the coloring is such that when no optical signals are generated, the opaque embodiment is realized from the outside to the electronic components. In particular, it is provided that the cover is formed of glass. In addition to the high technical functionality with respect to the mechanically stable design, the corresponding mounting option and the rigidity of this embodiment, the transmission of optical signals is also made possible accordingly. In addition, such a design is also positive in terms of the visual appearance and a high degree of quality thus mediated.

It can also be provided that the cover is made of plastic.

Furthermore, the invention also relates to a household refrigerator with a housing in which a receiving space for food is formed. The domestic refrigerator further comprises a door according to the invention or an advantageous embodiment thereof, which is pivotally mounted on the housing.

With the indications "top", "bottom", "front", "rear", "horizontal", "vertical", "depth direction", "width direction", "height direction" are the intended use and intended arrangement of the door or the Device and given at a then before the door or in front of the device and in the direction of the door or the device looking observer given positions and orientations. Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respectively specified combination but also in other combinations or in isolation, without the frame to leave the invention. Thus, embodiments of the invention are to be regarded as encompassed and disclosed, which are not explicitly shown and explained in the figures, however, emerge and can be produced by separated combinations of features from the embodiments explained. Embodiments and combinations of features are also to be regarded as disclosed, which thus do not have all the features of an originally formulated independent claim. Embodiments of the invention are explained in more detail below with reference to schematic drawings. Show it:

Fig. 1 is a schematic representation of an embodiment of a household refrigerator according to the invention;

2 is a perspective sectional view of a portion of an embodiment of a door according to the invention; and

Fig. 3 is a perspective sectional view of a portion of another embodiment of a door according to the invention.

In the figures, identical or functionally identical elements are provided with the same reference numerals. In Fig. 1, a household refrigeration device 1 is shown in a perspective view, which is designed for receiving food and which may be, for example, a refrigerator or a freezer or a fridge-freezer combination unit.

The household refrigerator 1 comprises a housing 2 in which at least one receiving space 3 for food is formed. On the housing 2, a door 4 is pivotally mounted. With the door 4, the receiving space 3 can be closed.

2, a first embodiment of the door 4 is shown in a perspective sectional view. This comprises a door inner wall 5 and a door outer wall 6 spaced therefrom. The door inner wall 5 faces the receiving space 3 in the closed state of the door 4.

Between the door inner wall 5 and the door outer wall 6, a gap 7 is formed, which is filled with a thermally insulating material 8, for example, an insulating foam.

At the door outer wall 6, a handle 9 is arranged in the embodiment. In the illustration according to FIG. 2, the door 4 is closed in an upper area with a door closure strip 10. The door closure strip 10 thus represents the outer component at this narrow upper edge of the door 4.

The door closure strip 10 is also at the same time also a cover 1 1 of an electronic display device 12, which generates optical information to be displayed in the direction of the door closure strip and transmits through the door closure strip to the outside. The electronic display device 12 therefore has no further own and the door seal strip 10 additional and separate cover. The electronic display device 12 is formed in the door 4 and comprises electronic components 13, which are arranged, for example, on a circuit carrier 14. In this context, the electronic components 13 also comprise a plurality of light sources which emit optical signals in the direction of the door seal strip 10 and thus also the cover 11. The cover 1 1 is thus integrated into the door closure strip 10, wherein this door closure strip 10 is formed as a one-piece component, in particular made of glass. As can be seen, the door closure strip 10 extends over the entire width (extension in the z-direction) between the door inner wall 5 and the door outer wall 6.

In addition, this door closure strip 10 extends over the entire width (x-direction) of the door 4 and thus also over the width of the door inner wall 5 and the door outer wall. 6

In the embodiment shown, the one-piece door closure strip 10 is formed as a U-profile, which has a U-bottom 15 and U-side walls 16 and 17. The U-shape is oriented so that it is oriented with the opening of the U-shape in the direction of the gap 7 and thus oriented to the door inner wall 5 and the door outer wall 6 out.

As can also be seen, a receiving space 18 is formed by the U-shape, in which the electronic components 13 are accommodated.

In addition, it can be seen that the emission of the optical signals in the direction of the U-bottom 15 and / or in the direction of the receiving space 3 facing away from the outer or front U-side wall 17 can take place. Thus, optical information can be radiated through the U-bottom 15 and / or the U-side wall 17 and presented or perceived outside the door.

The receiving space 3 facing U-side wall 16 has a receiving slot 19, in which the door inner wall 5 extends into and is held therein.

In addition, it can be seen that the U-side walls 16 and 17 in the vertical direction and thus in the y-direction with upper ends of the door inner wall 5 and the door outer wall 6 are arranged overlapping and overlap or overlap on the outside.

The cover 1 1 and thus also the door closure strip 10 are formed in the region of the optical displays to be transparent to light in the visible to humans spectral range. The cover 1 1 and thus also the door closure strip 10 are moreover made of a dyed and the view from the outside to the electronic components 13 in a non-information optically indicating state of the display device 12 at least hindering, especially avoiding material formed. In the embodiment shown here, the insulating foam 8 extends to the display device 12.

In Fig. 3, a further embodiment is shown in which, in contrast to the illustration of FIG. 2, an additional separate connection part 20 is present, which closes the gap 7 of the display device 12 out. The connecting part 20 is connected to the door inner wall 5 and the door outer wall 6 and thus also closes this gap 7 from. In this embodiment, moreover, it is also provided that the door inner wall 5 does not extend into a slot 19, which is not formed here in the U-side wall 16. In addition, it can be seen that the door closure strip 10 and thus also the cover 1 1 receives the connection part 20 or this connection part 20 is surrounded on the outside of the door closure strip 10.
