Description

Technical field

The invention relates to a refrigerator with at least one illuminated area.

State of the art

Modern kitchens usually have, along with central lighting (for example, ceiling lights or a halogen general lighting fixture), worktop lighting. Usually it is located on the lower side of the upper cabinets and basically completely illuminates the entire working surface. Individual lighting solutions also include other lighting devices, for example, lighting a rack or a table for eating built-in kitchen equipment, or directional lighting of noteworthy corners, objects, paintings, etc.

Finally, it is generally known that full illumination by point or tubular built-in light sources of the interior of kitchen equipment such as refrigerators, freezers, ovens, microwave ovens, etc. This interior lighting allows the user to find objects in the interior and navigate it.

Disclosure of invention

The basis of the invention is to propose a lighting solution that fundamentally goes beyond the known lighting concepts, emphasizing individual parts of the refrigerator, and has significantly expanded design capabilities

This problem is solved by a lighting device for lighting the interior of the refrigerator, which consists of a large number of white light-emitting diodes and at least one light diffuser located near the luminescence zone to distribute the directional light emitted by the LEDs over a large surface. At the same time, an inductive transmitting device is provided on the side wall and / or door of the refrigerator or freezer cabinet for inductive power supply of white light emitting diodes in several predetermined positions.

In a preferred embodiment of the invention, on the side edges, and / or on the upper edge, and / or on the lower edge, or near these edges, diffusely reflecting, in particular, the dull white back wall of the inner space, or the side wall of the inner space, or the inner side the door is located essentially linear system of white light emitting diodes with the direction of radiation at an acute angle, in particular, almost flat to the plane of the rear wall of the inner space, or the side wall of the inner space, or the inside of the door. The linear system of LEDs is arranged in such a way that it diffusely reflects the light emitted by the LEDs on a large part of its surface.

In addition, a large area light guide element and a substantially linear system of white light emitting diodes with a radiation direction substantially parallel to the plane of the light guide element can be provided on the rear wall of the interior space, or the side wall of the interior space, or the inside of the door, at least along one of its lateral edges. In this case, at least on a part of the rear wall of the inner space, or the side wall of the inner space, or the inner side of the door, an exit to a large area of light of the LEDs introduced through the edge zone into the light guide element is caused.

Preferably, the planar light guide element substantially forms or overlaps the entire rear wall of the interior space, or the side wall of the interior space, or the inside of the door.

In the refrigerator, at least one panel may be provided in the form of a planar light guide element. At least on one edge of the tablar, in particular on the leading edge with a metal or plastic edging, a substantially linear system of white light emitting diodes can be arranged with the radiation direction essentially parallel to the plane of the tablar, so that the light of the LEDs introduced through the edge or edges , is radiated at least over one plane of the tablar.

In addition, a substantially linear system of white light emitting diodes with a sharp angle, in particular almost flat to the plane of the inner side of the door, can be located on the rear edge of the door shelf adjacent to the inner side of the door, so that it diffuses over a large part of its surface reflects light emitted by LEDs.

For inductive power supply of white light-emitting diode systems located on the edges of tabs or door shelves, low-voltage contact means are provided in several preset positions of the tabs and door shelves, which are located in the side wall and / or in the corners of the tabs and door shelves of the refrigerator or freezer.

The refrigerator according to the invention may be provided with a surface comprising a color hologram on the front side or in the interior.

It is possible to make a refrigerator in the form of a domestic refrigeration unit, especially in the form of a free-standing refrigerator.

The proposed solution, along with the planned expansion of aesthetic possibilities, can improve consumer properties due to the "direction of the user with light."

Advantages and useful properties of the invention arise from the dependent claims and from the following description and indications of preferred embodiments with reference to the figures.

Figure 1 explains the main idea of the invention in the form of schematic diagrams, namely, the presence of active or passive glow edges or planes on the front side of the elements of kitchen equipment, including a refrigerator capable of glowing. Figure 2 specifically indicates the use of passively glowing edges as emergency lighting, enabling the user to navigate in the kitchen in the event of a power outage, as well as to deliberately create soft intimate lighting, which, however, emphasizes certain elements and allows you to confidently handle with kitchen equipment.

On figa-3C also in the form of schematic schematic drawings presents the possibility of surface coating of the edges, planes and manipulators of the refrigerator. Such coatings can be realized as mechanically and chemically resistant coatings especially for manipulators and controls that are often used. On figa shows a passive luminous coating, on figv - resistant color holograms, and figs shows active and passive luminous surface materials.

From the examples shown in FIGS. 1-3C, it becomes clear that in the first embodiment of the invention, the edge of the door, drawer or housing is provided as a luminous edge, mainly in the form of a linear row of LEDs. In another embodiment, the inner edges of the insert shelf or other element of the interior space are provided as the luminous edge, mainly in the form of a linear row of LEDs. In addition, the edges of the handles can be provided as a luminous edge, mainly in the form of a linear row of LEDs.

The mentioned versions of execution can be further modified in such a way that instead of active lighting (in particular, using the aforementioned series of LEDs), passive lighting with surfaces using reflected light is used.

Both possibilities can be used further to illuminate the surface of the refrigerator, especially the front surface of the door or drawer, as well as the working surface or the inner walls of these elements. Lighting the surface is also possible by placing on this surface a discharge lamp with a large surface and a shallow depth, which in the limit can completely cover or form this surface.

While colored light accents (known in other fields of application) can be created using colored LEDs or colored fluorescent tubes, color-neutral illumination of the edges and surfaces of kitchen elements can be realized in a particularly energy-efficient way using the recently appeared white LEDs Sveta. Very high energy efficiency and low operating voltage of these elements make it possible to realize a very simple connection of these elements and refuse any cooling.

On figa-4I using a large number of schematic diagrams shown examples of the possibilities of implementing the concept of the invention on refrigerated furniture and refrigeration units. These figures in particular include claims 2 to 7 of the claims, which together with the drawings show preferred embodiments of the invention as applied to kitchen refrigeration appliances.

At the same time, FIGS. 4F-4I specifically consider lighting options for the ice maker, as a special functional area of the refrigerator, which is desirable to highlight with light, both from functional and aesthetic considerations.

Using the agreed lighting parameters (for example, color and / or luminous intensity and / or width of light strips, etc.), one can emphasize the generality or similarity of functions and distinguish this functional area from others. Similar possibilities of differentiating the hot and cold functional areas of a refrigerator within the framework of the “box concept” are indicated by the schematic drawing of FIG. 5.

Figures 6 to 9 show, in the form of schematic drawings, specific examples of placement of light sources for realizing the above-mentioned luminous surfaces, especially for the interior of the refrigerator. At the same time, Figures 6 and 7 show designs with one or (preferably) several tubular lamps. It can be either luminescent or halogen tubes known per se, or rows of LEDs placed in the tubes. In particular, Fig. 8 shows such lamps which can be rotated or have a rotatable reflector having the shape of a part of a cylinder.

In Fig. 9, the possibility of forming a luminous surface (for example, a completely luminous shelf of a refrigerator) using narrow sources of light located at the edges is shown sketchily. A linear row of LEDs can be used as such a light source, and the “deflection” and scattering of the light emitted by them occurs very effectively in planar elements with light-conducting properties, which are known to be used in displays of electronic devices (laptop computers, mobile phones).

It should be strongly noted that the invention, along with the above-mentioned and sketchy examples presented in the figures, can be implemented in many other forms. It is further emphasized that any combination of aspects and options depicted in the figures should also relate to the field to which the invention is protected.
