Description

Technical field

The present invention relates to a refrigerating apparatus, such as, for example, a home refrigerator or freezer with a cabinet and a door attached to the cabinet, which define a thermally insulated internal cavity. Typically, such refrigerators are equipped with lighting of the internal cavity, which automatically turns on when the door is opened. Typically, such lighting is one single lamp attached to the side inner wall of the housing.

State of the art

Such illumination of the internal cavity illuminates objects in its immediate vicinity, very brightly, and emits unwanted heat to these objects. Objects located at a greater distance from the lamp or not on the shelf on which the lamp is mounted, on the contrary, are poorly lit. In addition, with such illumination of the inner cavity, it is difficult to provide satisfactory illumination of objects located in front of the inner cavity without blinding the user who is looking into the open inner cavity from the front.

A refrigerator is known from EP 0971186 A2, corresponding to the restrictive part of claim 1, in which several luminaires are located on the inside of the housing. These lamps, which, in particular, can be located on opposite sides of the internal cavity or be distributed at a considerable distance along its height, provide uniform illumination of the internal cavity. However, the installation of such a refrigerator is extremely time-consuming, since the installation and electrical connection of the fixtures requires a large number of holes in the inner wall of the housing. In addition, in this refrigerator, the heat generated by the luminaires is inevitably transferred to the internal cavity.

Disclosure of invention

An object of the present invention is to provide a refrigerator which, by simple means, provides uniform illumination of an internal cavity without dazzling a user.

This problem is solved by a refrigerator with the features of paragraph 1 of the claims. If at least one lamp for illuminating the inner cavity is installed on the inner side of the door facing the inner cavity, the distance between the lamp and objects illuminated by it can be increased, which allows for uniform illumination without shadowing by objects located close to the lamp. In addition, the lamp is outside the main field of view of the user who is looking inside the open refrigerator, so that the risk of direct dazzle is practically eliminated.

In order to completely eliminate the possibility of blinding, it is desirable that the lamp radiates within the angle, the top of which is formed by the lamp itself, and which is bounded on one side by a perpendicular to the inner side of the door, and on the other hand by a segment on the inner side of the door, directed from the lamp to that side of the door which is fixed to the housing.

This means that when the door is open and forms a right angle with the body, the radiation of the lamp is directed mainly inside the refrigerator; there is no radiation in the direction of the user standing in front of the open refrigerator that could blind him.

Such a lamp is preferably located in the middle of the door in the direction of its width. At the same time, it will always be located correctly, regardless of which side the door is attached to.

If the lamp is not installed in the middle, then in this case it is advisable to provide two mounting places in the door on both sides of the middle line so that you can optionally install the lamp on one of them so that the lamp is located correctly, on which side the door is attached .

Preferably, in this case, the lamp should be installed on that of the mounting places, which is located on the side of the middle line, which is facing the place of fastening the door to the housing. In this case, the risk of shadowing by the user is less than if the lamp was installed on the side of the door remote from the fixing point.

In a preferred embodiment, the luminaire is mounted on the door of choice with the possibility of orientation in two directions, rotated 180 ° relative to the axis perpendicular to the door. This is especially advisable if the lamp should emit mainly not in the direction of the specified axis, but in the area of the angle between the axis and the segment of the inner side directed from the lamp to the side of the door that is mounted on the housing.

In this case, the rotation allows you to direct the beam to the selected side of the door, without changing the configuration of the lamp itself. If the luminaire is installed on the middle line of the door, the place of its installation must be designed so that it is possible to mount the luminaire with an orientation in both directions; with two mounting locations, it is enough that only one orientation is possible at each location.

In order to ensure a non-blinding orientation of the light beam, an adjustable beam forming element is preferably mounted on the lamp. Such an element, in particular, may be a reflector or screen. It is also possible to use a light-reflecting element.

If the internal cavity of the refrigerator is divided into several compartments, then at least one lamp should be at the height of each compartment to ensure uniform illumination. This requirement can be met with the help of several lamps located on the door at different heights; but one luminaire is preferred, the height of which covers several compartments.

Brief List of Drawings

Other features and advantages of the invention arise from the following description of examples of implementation of the invention with reference to the accompanying drawings, which show:

Figure 1 is a perspective projection of the invention of the refrigerator with an open door;

Figure 2-5 is a partial sectional view of the refrigerator door with various variants of fixtures according to the invention; and

In Fig.6 is a perspective projection, similarly to Fig.1, another embodiment of the refrigerator proposed by the invention.

The implementation of the invention

Figure 1 shows a perspective projection of a home refrigerator 10, as an example, proposed by the invention of the refrigeration apparatus. Door 12 is mounted on the housing 11 of the refrigerator 10 with a possibility of rotation. The housing 11 and the door 12 define an internal cavity 13, which is divided into several compartments by shelves 16. The door 12 has an outer wall 14 of sheet metal and an inner wall 15 made of plastic by the deep hoods, which are interconnected at the edges and limit the cavity filled with heat-insulating foam. The inner wall 15 has a generally smooth inner side 18, framed around the perimeter by a rib 19, which, when the door is closed, protrudes slightly into the inner cavity 13. The lamp 20, from which only the outer screen is visible in the figure, extends in the middle of the inner side 18 along its entire height.

A first example of a possible design of the luminaire 20 is shown in FIG. On the inner side 18 there is a recess 21 in the form of a cylindrical segment in which the light source 22 is placed, in this example a fluorescent tube. The ends of the fluorescent tube are connected by brackets 23 to the inner wall 15, along which electric power wires 24 for the lamp 20 also pass. Each of the two required wires of the power wires 24 at the height of the corresponding bracket 23 can be brought into the cavity 25 on the door 12 and from there through the door hinge into the housing 11. Alternatively, one core of the power wire can be stretched in the recess 21 from one bracket 23 to the other, so that both wires pass into one single hole in the inner wall 15 of one and brackets 23.

Instead of a single fluorescent tube, of course, several light sources distributed over the height of the luminaire 20 can be used. In particular, a rod can be installed instead of the tube to which these light sources are attached, for example, halogen lamps or LEDs, and on which there are a pair of connecting clamps for connecting power wires with which these several light sources can be connected in series or in parallel.

The recess 21 is covered by a half-cylinder screen 26, preferably of transparent or translucent plastic. On the outside of the screen 26 is a plate-shaped shutter 27 extending along its entire length, which can be installed along the screen surface in one of two mirror-symmetric positions. In the position in which the shutter 27 is shown in the form of a contour bounded by a solid line, the shutter 27 concentrates the radiation in the angle zone between the line 30 perpendicular to the door at the height of the light source 22 and the part of the inner side 18 of the door lying to the right of it. This position is appropriate for the right installation of the door so as not to blind the user standing to the left of the door. If the door should be mounted on the left, to adjust the backlight, it is enough to move the shutter 27 on the opposite side of the screen 26, to the position shown by the dashed outline.

The luminaire 20 shown in section in FIG. 3 differs from that shown in FIG. 2 in that the shutter 27 is absent, and the screen 26 is made in the form of a sequence of prismatic segments. The segments are arranged so that they deflect the beam extending from the light source 22 in a clockwise direction, as shown in the example beam 28, which is shown in the figure. This also prevents or at least reduces the blindness of the user standing to the left of the door when the door mounted on the right, as assumed in the figure.

To adapt the radiation of this lamp 20 to the change in the side of the door attachment, it is enough to dismantle the screen 26 and install it again by turning 180 ° so that the rays deflect counterclockwise.

In the embodiment of FIG. 4, the light distribution is largely determined by a reflector 29 located in a recess 21 between the light source 22 and the inner wall 15. The reflector, which may have, for example, a parabolic or elliptical cross section, is mounted asymmetrically to direct the radiation mainly in the area between the line perpendicular to the door 39 and the inner surface 18 from the side of the door. The reflector 20 is rigidly connected to the screen 26, so that the entire lamp 20, consisting of a screen 26, a light source 22 and a reflector 29, can be completely removed from the door and mounted again by turning around 180 ° in advance to change the preferred backlight direction if the door should join on the left.

In the embodiment depicted in FIG. 5, the light source 22 and the reflector 31 are surrounded by a cylindrical screen 26. The entire luminaire 20 is completely, with a screen, a reflector and a light source, mounted on the inner side 18 of the door so that it can be manually rotated by its ends, adjusting the direction of radiation depending on which side the door is attached.

Another embodiment of a refrigerator in accordance with the invention is shown in perspective view in FIG. 6. The lamp 20 is shown here separately from the door 12. On the inner side 18 of the door 12 there are two mounting places 32, 33 prepared for the installation of the lamp 20. The mounting places 32, 33 can be made, for example, in the form of recesses corresponding in shape to the lamp 20, in which the latter can be installed using fasteners or other fastening devices, and are indicated by other fastening devices or by affixed or pasted markings. At each mounting location 32, 33, electrical contact means are provided for powering the luminaire 20, in this case in the form of a pair of contact sockets. Contact slots 34 are located at both mounting locations 32, 33 at various heights so that the luminaire can be installed at both mounting locations with 180 ° rotation relative to the normal to the door surface. In this embodiment, the luminaire 20 is also designed so that the radiation is directed preferably with an inclination relative to the normal 30 to the door surface. The luminaire 20 must always be installed on that mounting location 32 or 33, which is located closer to the fixed edge of the door 12, i.e. in the example shown here at the mounting location 32. Just like the luminaires described with reference to FIGS. 2-5, the luminaire 20 in this case is also designed to radiate with a slope relative to the normal 30 to the door surface, namely, so that when installed at the mounting site 32, its radiation with the door 12 open was mainly directed into the cavity 13.

If you want to rearrange the door 12 to the left side of the housing 11, then the lamp 20 needs to be moved to the mounting place 33. Since, due to the appropriate placement of the contact sockets 24, it is possible to rotate the lamp 20, then in this case the lamp will shine inside the cavity 13 without blinding the user.

Instead of a separate luminaire located along the entire height of the door 12, or at least for the most part, it is, of course, possible to provide several luminaires distributed over the height of the door, similarly to that described above.
