Definitions
- the invention relates to a household refrigerator with an at least partially transparent door according to the preamble of claim 1.
- the lighting in the refrigerator is usually only activated when the refrigerator door is opened to access the refrigerator. When the door is closed, the lighting is switched off, so that the refrigerator compartment is only lit insufficiently above the transparent door.
- Such refrigerators are known as wine storage cabinets, which are used both as a stand and as built-in appliances.
- a constant temperature is to be maintained, on the other hand, however, the wine connoisseur should be given an overview of his stored bottles, so that he can choose a wine with the door closed.
- An example of such a refrigeration device is disclosed in DE 202 20 797 U1.
- the invention has the object of providing the most efficient lighting for refrigerators with a transparent door in such a way that an optimal presentation of the refrigerated or frozen goods, which is located behind the door, permanently enabled.
- the stored refrigerated goods is optionally illuminated by the action of a user with the refrigerator door closed and so in the cold room at poor lighting conditions in the vicinity of the refrigerator safely localized, especially when the refrigerator is equipped with vertically spaced superposed refrigerated goods storage for storing the refrigerated goods.
- at least one lighting device is associated with the compartments generated by the distance of the refrigerated goods shelves.
- the refrigerator compartment is particularly energy-efficient, but can also be illuminated with optimum lighting, if the brightness of the interior lighting is adjustable in steps or infinitely variable. This can be accomplished advantageously by the use of an electronic control circuit.
- the control circuit is particularly advantageously designed if it is programmable by a user until then, that the interior lighting is switched off for at least a previously determinable period of time and after this period, the electronic control circuit automatically resumes the interior lighting.
- the presentation ofdetial. Frozen food is used, LED used. These have a much lower temperature development than filament lamps and thus have a significantly better energy efficiency. Especially in this type of refrigerators, in which the interior lighting is turned on not only when the door is open but often for many hours a day, but especially the high durability of the LED, which almost excludes a failure of the lighting.
- the LED are connected to electronic circuits, via which they can be switched on and off or optionally reduced in their intensity. Since LEDs are very simple and quick to switch, a variety of lighting effects can be realized, depending on which refrigerated goods to illuminate, what external conditions prevail or can be controlled according to the time of day or taste of the operator of the refrigerator. This can be particularly easily realized by the control of the LED can be operated via the control electronics of the refrigerator. It would also be conceivable to provide a motion sensor which the Lighting changes in color or brightness as soon as someone approaches the refrigerator.
- colored LEDs are used to realize a lighting for the presentation of the refrigerated goods in a desired color.
- a particularly effective presentation can be achieved, which can also take into account the characteristics of the goods. It is conceivable to combine LEDs of different colors or white and colored LEDs in order to achieve desired color effects. Especially when the control is realized so that LEDs of different colors can be switched independently of each other, a variety of color mixtures could be produced in a refrigerator, so that an ideal match of presentation light and cooling or frozen food is guaranteed.
- LEDs can be easily mounted, fitted or inserted on almost all interior surfaces of the refrigeration device, such as intermediate floors, side walls or ceilings. As a result, parts or entire inner walls of the refrigerator with LED and thus lighting can be equipped for presentation, so that a uniform illumination of the entire refrigerator can be guaranteed. This has a particularly advantageous effect that LEDs require very little space and are therefore particularly easy to integrate.
- interior surfaces of the refrigeration device have recesses into which LEDs are inserted. These are covered with transparent surfaces, so that the LEDs are protected and on the surface of the interior surfaces creates a smooth, easy-to-clean surface.
- the transparent areas may be used as refractive surfaces, e.g. Lenses be formed.
- the transparent surface can thus optimize the emission of the LED and at the same time reduce the risk that the lighting will be damaged when removing items to be refrigerated or frozen.
- the lighting is protected integrated into the surface of the refrigeration device interior.
- LEDs preferably a plurality of LEDs are simultaneously placed on heat sink, which directly removes the heat generated by them.
- heat sink can advantageously be arranged behind the interior surfaces, especially with integrated LEDs. It makes sense if it is connected to the cooling circuit.
- it is itself equipped with fastening elements, such as openings or projections, so that it, and with it the LED attached to it, can be attached directly to the interior surface.
- a translucent cover which e.g. made of glass or plastic can be realized. This also protects the LED from damage caused by refrigeration or frozen food or the user when cleaning the device, at the same time provides protection against contamination and can be designed in a particularly advantageous manner so that it optimally distributes the light of the LED over the illuminated interior.
- the transparent cover can also be designed as a light-scattering luminous surface, into which the light of the LED is coupled and from which it is distributed over a large area, so that a large part of the interior can be illuminated with a few LEDs.
- the LED is designed as an organic LED.
- These light-emitting diodes are particularly well suited for implementation in large-area light sources, so that I can be achieved particularly simple uniform illumination of the interior of the refrigerator.
- Fig. 1 shows schematically the inner housing of an inventive refrigeration device with mounted intermediate plates in a 3D view
- Fig. 4 shows the bottom of an intermediate plate with a mounted light strip in the rear view.
- Figure 1 shows an inventive refrigeration device, which is designed as a cooling device and the cooled interior 1 of an inner housing 2 with a ceiling 3 and a door 4 is limited.
- the door 4 consists of a frame 5 and a transparent pane 6.
- the pane 6 is chosen so large that it gives the user a good overview of the interior 1 and the refrigerated goods stored therein.
- the frame 5 is only a narrow edge, which is wide enough, a seal not visible here, which seals the door 4 to the inner housing 2, and to receive the stopper 7.
- the interior 1 of the refrigerator is divided by shelves 8, which are shaped so that they can accommodate lying on top of bottles. Between individual shelves 8 are intermediate plates 9. These intermediate plates 9 are fixedly connected to the inner housing 2.
- the intermediate plate 9 consists inter alia of a lower part 10 and a top part, not shown here.
- FIG. 2 shows the lower part 10 of an intermediate plate 9 in plan view.
- each lower part 10 of the intermediate plates 9 has in the vicinity of its front edge mounting direction openings 11, are inserted through the lights 12, the bulbs are designed as LED 19 and their light through a
- Plastic lens 20 emerges.
- the lighting direction of the lights 12 is in the installation direction from top to bottom.
- the luminaires 12 are integrated into the lower part 10 of the intermediate plates 9 or the ceiling 3 of the cooling device such that the edge 13 delimiting the front side of the luminaire 12 is flush with the outer surface 14 of the lower part 10 or flush with the surface of the ceiling 3 concludes. This ensures easy cleaning of the outer surface 14 of the base 10 and prevents the lamp 12 from being damaged by careless insertion or removal of a bottle.
- a plastic lens 20 as the front end of the luminaire 12, the light emitted by the LED 19 can be used. witnessed light in the cooled interior 1 are distributed so that the entire interior 1 is illuminated.
- the LED 19 are, as shown in Figure 3, placed on a rail 16.
- This can be made of aluminum or another, good heat conductive material, such as copper or brass, and serves as a heat sink and holder for the LED 19.
- the rail 16 serves as a fastening tape.
- openings 18 in the rail 16 through which the fastening means 17 shown in Figure 4 are inserted in order to attach the light strip 15 to the lower part 10 of the intermediate plate 9.
- FIG 4 shows the lower part 10 of the intermediate plate 9 described in Figure 2 in rear view.
- the light strip 15, as well as the permanently connected to him LED 19 inclusive electronic conductor tracks are connected by means of fastening means 17 with the lower part 10.
- the distance of the LED 19 on the fastening band 16 is selected so that the lights 12 through the openings 1 1 in the lower part 10 fit
- the purpose of the refrigerator is to cool and present goods - especially bottles - at the same time.
- they are irradiated by means of the lamps 12 which are located in the intermediate plates 9 and the ceiling 3.
- the lights 12 are integrated in a simple manner in the intermediate plates 9 and 3 ceiling, whereby the smooth user-friendly surface of this is maintained.
- the use of only one rail 16 both as a holder for LED 19 or assembly line, as well as a heat sink for multiple LED 19 ensures easy installation and a significant cost savings.
- the plastic lenses 20 also have a multiple function. On the one hand, they protect the LED 19 from damage and ensure a smooth finish with the outer surface 14 of the intermediate plate 9, on the other hand, they are used for targeted light emission. LIST OF REFERENCE NUMBERS
