Definitions
- the present invention relates to a refrigerator, such as a refrigerator or a freezer, with a body and a door attached to the body, which delimit a heat-insulated interior.
- a refrigerator such as a refrigerator or a freezer
- Such refrigeration devices are usually provided with interior lighting which is switched on automatically when the door is opened.
- interior lighting comprises a single luminous element which is attached to a lateral inner wall of the body.
- Such interior lighting illuminates objects in their immediate surroundings very brightly and also emits heat to these objects in an undesirable manner. Objects that are at a greater distance from the lamp, possibly on other shelves in the interior than the one on which the lamp is attached, are poorly illuminated. In addition, with such interior lighting, it is difficult to illuminate objects in the front area of the interior satisfactorily without dazzling a user who looks into the open interior from the front.
- a refrigeration device according to the preamble of claim 1 has become known, in which a plurality of luminous elements are attached to the inside of the body. These luminous elements, which can be attached, inter alia, on opposite sides of the interior or can extend over the greater part of its height, enable homogeneous illumination of the interior.
- the assembly of the refrigeration device is extremely complex since a large number of openings in the inner wall of the body are required in order to mount the lighting fixtures and to make electrical contact.
- waste heat from the lamps used is inevitably given off to the interior of this refrigeration device.
- the object of the present invention is to provide a refrigeration device which enables uniform lighting of the interior without risk of glare for the user with simple means.
- the object is achieved by a refrigeration device with the features of claim 1.
- the at least one luminous element for illuminating the inner space By attaching the at least one luminous element for illuminating the inner space to an inner side of the door facing the inner space, the distance between the luminous element and objects illuminated by it can be made larger, so that uniformly bright illumination can be achieved, and shadowing by objects placed close to the illuminant is excluded.
- the lamp lies outside the main viewing angle of a user who looks inside the opened refrigerator, so that there is hardly any direct glare.
- the luminous element radiate predominantly into an angular region, the apex of which forms the luminous element itself and which, on the one hand, through a perpendicular on the inside of the door and, on the other hand, through a section running from the luminous element to the hinged side of the door is limited from the inside.
- Such a luminous element is preferably arranged centrally in relation to the width direction of the door. So it is always suitably placed, regardless of which side the door is hinged on.
- the light fixture is placed off-center, it is advisable to provide the door with two mounting locations on either side of the center line, to which the light fixture can be mounted, so that it can always be placed appropriately, depending on which side the door is hinged on can.
- the luminous element is preferably mounted on that of the two assembly stations which is located on the side of the center line facing the hinged side of the door.
- the risk of shadowing by the user himself is less than if the luminous element were mounted on the side of the door away from the stop.
- the luminous element on the door can optionally be mounted in two orientations rotated relative to one another by 180 ° about an axis perpendicular to the door. This is particularly expedient if the luminous element is not to radiate preferably in the direction of said axis, but rather in the angular range between the axis and the section of the inside extending from the luminous element to the hinged side of the door.
- the rotation enables the beam direction to be adapted to the selected stop side of the door without changes to the configuration of the luminous element itself being necessary.
- the filament is mounted in the middle of the door, its mounting location should be designed to allow the filament to be fastened in both orientations; With two off-center assembly locations, it may be sufficient if each only allows assembly in one orientation.
- an adjustable beam-shaping element is preferably attached to the luminous element.
- This element can in particular be a reflector or an aperture.
- a refractive element can also be used.
- the interior of the refrigerator is divided into a plurality of compartments, in order to achieve uniform illumination, there should be at least one luminous element at the level of each compartment. This requirement can be met by several light fixtures, which are attached to the door at different heights; a single luminous element is preferred, which extends over the height of several compartments.
- Figure 1 is a perspective view of a refrigerator according to the invention with the door open.
- FIG. 2-5 partial sections through a refrigerator door with different variants of lighting elements according to the invention
- Fig. 6 is a perspective view analogous to FIG. 1 of another unfolding of a refrigerator according to the invention.
- Fig. 1 shows a perspective view of a refrigerator 10 as an example of a refrigerator according to the invention.
- a door 12 is hinged to a body 11 of the refrigerator 10.
- Body 11 and door 12 delimit an interior space 13 which is divided into a plurality of compartments 17 by shelves 16.
- the door 12 has an outer wall 14 made of sheet metal and an inner wall 15 deep-drawn from plastic material, which are connected to one another at the edges and delimit a cavity filled with insulating foam.
- the inner wall 15 has a substantially flat inside 18 which is framed by a circumferential rib 19 which projects slightly into the interior 13 when the door is closed.
- a luminous element 20, of which only an outer screen can be seen in the figure, extends centrally on the inside 18 over its entire height.
- FIG. 2 A first example of a possible internal structure of the luminous element 20 is shown in FIG. 2.
- the inside 18 has a cylindrical segment-shaped recess 21, in which an illuminant 22, here a fluorescent tube, is held.
- the fluorescent tube is in each case connected at its longitudinal ends by support arms 23 to the inner wall 15, through which an electrical supply line 24 for the luminous element 20 also extends.
- an electrical supply line 24 for the luminous element 20 also extends.
- the supply line 24 for the luminous element 20 also extends.
- one wire of the supply line can be guided from one support arm 23 to the other within the recess 21, so that both wires run through a single opening in the inner wall 15 on one of the support arms 23.
- a single fluorescent tube it would of course also be possible to use a plurality of illuminants distributed over the height of the luminous element 20.
- a rod-shaped support can be provided, on which these several light sources, for example halogen bulbs or light-emitting diodes, are mounted, and which has a pair of connection terminals for connection to the supply line, to which these several light sources are connected in parallel or in series ,
- the recess 21 is covered by a semi-cylindrical screen 26, preferably made of a transparent or translucent plastic.
- a strip-shaped diaphragm 27 Arranged on the outside of the screen 26 is a strip-shaped diaphragm 27 which extends over its entire height and which can be displaced along the surface of the screen 26 between two positions opposite one another in mirror image.
- the diaphragm 27 concentrates the radiation on an angular range between the line 30 standing vertically on the door at the level of the illuminant 22 and the part of the inside of the door 18 to the right of this Door makes sense to avoid glare to a user standing to the left of the door. If the door is to be hinged on the left, it is sufficient to adjust the light emission to move the diaphragm 27 to the opposite side of the screen 26 into the position shown as a dashed outline.
- the lamp 20 shown in section in FIG. 3 differs from that of FIG. 2 in that there is no diaphragm 27 and that the screen 26 is constructed as a sequence of prism-shaped segments.
- the segments are arranged such that they deflect a light beam emanating from the illuminant 22 in a clockwise direction, as shown by way of example in the figure on a light beam 28. This is also effective in order to prevent or at least reduce the glare of a user standing on the left of the door assumed to be hinged on the right.
- this luminous element 20 In order to adapt the radiation of this luminous element 20 to a change of stop of the door, it is sufficient to dismantle the screen 26 and to re-mount it rotated by 180 °, so that the rays are deflected counterclockwise.
- the light distribution is essentially determined by a reflector 29 mounted between the illuminant 22 and the inner wall 15 in the recess 21.
- the reflector which may have a parabolic or elliptical cross section, for example, is arranged asymmetrically in order to achieve a light emission predominantly in the region between the line 30 perpendicular to the door and the part of the inside 18 on the stop side.
- the reflector 20 is anchored to the screen 26, so that the entire filament 20, consisting of the screen 26, the illuminant 22 and the reflector 29, is separated as a unit from the door and rotated by 180 ° around the line 30 can be reassembled to change the preferred direction of radiation if the door is to be hinged on the left.
- the illuminant 22 and a reflector 31 are surrounded by a cylindrical screen 26 all around.
- the complete luminous body 20 with shade, reflector and illuminant is rotatably held at its longitudinal ends on the inside 18 of the door and, depending on which side the door 12 is attached to, can be rotated by hand in order to adapt the direction of radiation.
- FIG. 6 Another embodiment of the refrigerator according to the invention is shown in FIG. 6 as a perspective view.
- the luminous element 20 is shown separately from the door 12 here.
- the assembly sites 32, 33 can e.g. be defined as a recess adapted to the shape of the luminous body 20, in which the latter can be latched or otherwise fastened, by other fastening means or by a recorded or glued-on marking.
- electrical contact means here in the form of a pair of sockets, are provided for the power supply of the luminous element 20.
- the sockets 34 are located at the two assembly locations 32, 33 at different heights, so that the luminous element can be mounted at the two assembly locations in each case rotated through 180 ° about the surface normal of the door.
- the luminous element 20 is constructed in such a way that it radiates preferably obliquely to the surface normal 30.
- the luminous body 20 should always be installed at the assembly site 32 or 33 that is closer to the struck edge of the door 12, in the case shown here at the assembly site 32. The illuminant described with reference to FIGS.
- the luminous body 20 is constructed in such a way that it radiates at an angle to the surface normal 30, specifically in such a way that, when it is installed at the assembly site 32, it preferably radiates into the interior 13 when the door 12 is open.
- the luminous element 20 must also be moved to the assembly site 33. By doing required due to the placement of the bushings 24 rotation of the luminous body 20 ensures that it radiates in this position is open, 'door into the interior space 13 without a user to blind.
- a single luminous element which extends over the entire height of the door 12 or at least a large part thereof, it is of course also possible to provide a plurality of luminous elements distributed over the height of the door in an analogous manner to that described above.
