Abstract

A refrigerator with interior lighting (6), fitted with a control circuit (3) for adjusting the intensity of said interior lighting (6) according to a brightness value detected by a light-sensitive element (4).

Description


  



   Refrigerator with interior lighting The present invention relates to a refrigerator with interior lighting.



  Refrigeration devices such as refrigerators or freezers are conventionally provided with interior lighting which is automatically switched on and off by a switch arranged on the door of the device.



  The illuminants currently used for the interior lighting of refrigeration appliances actually only convert a small fraction of their electrical power consumption into light output; the vast majority of the power consumption is converted into heat, which undesirably heats up and dissipates the interior. This heat input could of course be avoided by dispensing with interior lighting; on the other hand, the lighting is felt to be necessary in order to be able to find a desired object quickly in the interior.



  The object of the present invention is to provide a refrigeration device in which the heating of the interior can be reduced by illuminating it, without this having to be bought with a reduction in comfort for the user. On the contrary, comfort for the user can even be increased with skillful use.



  The object is achieved by a refrigeration device with interior lighting, which is equipped with a control circuit for controlling the output of the interior lighting as a function of a brightness value detected by a light-sensitive element.



  Such a control circuit allows the control, in particular the reduction, of the output of the interior lighting if the ambient brightness is sufficient to also adequately illuminate the interior of the refrigerator when the door is open.



  According to a first embodiment of the invention, the light-sensitive element is arranged on an outside of the refrigeration device in order to directly detect the intensity of the light in the vicinity of the refrigeration device. The light-sensitive element is preferably located on an operating panel of the refrigeration device, which together with the door forms the visible side of the refrigeration device and is thus exposed to an ambient light intensity that also falls into the interior of the refrigeration device when the door is open. The attachment to the control panel is also preferred because this allows the wiring of the light-sensitive element with the associated control circuit with little effort, together with the wiring of other control elements.



  According to a second embodiment of the invention, the light-sensitive element is arranged in the interior of the refrigerator, so that it is exposed to the combined intensity of the interior lighting and the ambient light (with the door open).



  This configuration allows in particular the regulation of the performance of the interior lighting depending on the degree of opening of the door or the shading of the interior by a user standing in front of it.



  In this embodiment, the light-sensitive element and the control circuit can be connected to the interior lighting to form a structural unit which can be installed as a prefabricated element in the interior. The effort for the assembly of such an element is not higher than that for the assembly of a conventional interior lighting.



  The control circuit is preferably equipped with an actuator for setting the dependence between the detected brightness value and the power of the interior lighting. By setting such an actuator, a user can adapt the behavior of the control circuit to his personal needs. So z.

   B. the control can be carried out in such a way that the power of the interior lighting set by the control circuit supplements the luminous intensity incident from the outside, so that an essentially constant brightness in the interior is always achieved regardless of the brightness of the surroundings, d. H. the power set by the control circuit changes in the opposite direction to a change in the ambient brightness; However, it is also conceivable to regulate the output of the interior lighting in a manner consistent with the ambient brightness with the aim of achieving a brightness in the interior that is proportional to the ambient brightness to a certain extent.

   If the room in which the refrigerator is installed is extremely brightly lit, for example by direct sunlight, and a user's eyes are adapted to this illuminance, he needs a higher illuminance in order to be able to find objects comfortably in the refrigerator in this as if he were looking into the refrigerator in a dim environment.



  Further features and advantages of the invention result from the following description of exemplary embodiments with reference to the attached figures. 1 shows a schematic section through a refrigeration device according to the invention; and FIG. 2 shows a view of a housing for interior lighting according to a second
Embodiment of the invention.



  Fig. 1 shows a schematic section through a refrigerator according to a first embodiment of the invention. Above the door 1 of the refrigerator there is a control panel 2 on its front, on which various setting and display elements, not shown in the FIG. B. are arranged for the temperature of the interior.



  Behind the control panel 2 is a control electronics 3, with which the various control and display elements are connected, and the z. B. controls the operation of a (not shown) coolant circuit in a conventional manner.



  Behind a translucent window of the control panel 2, a photodiode 4 is mounted as a light-sensitive element and supplies a photocurrent representative of the brightness in the vicinity of the refrigerator to the control electronics 3.



  The control electronics 3 is also provided with a switch 5 for detecting the opening or



  Closing door 1 connected. When the switch 5 indicates an open state of the door 1, the control electronics 3 supplies the interior lighting 6 with a current, the power of which it regulates as a function of the photocurrent of the photodiode 4.



  Examples of a possible control behavior of the control electronics 3 are shown as characteristic curves of the supply power P for the interior lighting as a function of the intensity of the ambient lighting or of the photocurrent I. In the case of low ambient brightness (I close to 0), the power P supplied to the interior lighting 6 is the nominal power Pmax of the illuminant of the interior lighting 6; With increasing ambient brightness I, the power P decreases and finally reaches the value 0 when the ambient brightness has reached such a value that it can be assumed that it is also sufficient to illuminate the interior of the refrigerator.



  Curve b shows an opposite control behavior: in the case of low ambient brightness (I close to 0), the interior is first illuminated with a low power Pmin, and with increasing brightness the lighting output also increases until it finally reaches the nominal output Pmax for which the interior lighting 6 is designed. This type of control is based on the consideration that, in the case of a low ambient brightness, the eyes of a user will generally be accommodated to such a brightness that excessive indoor lighting could dazzle him, while conversely, strong indoor lighting is also desirable in a very bright environment can be.



  Which of the two control strategies is ultimately perceived by a user as more pleasant and appropriate may depend on the user's habits and the conditions under which the refrigerator is installed. It is therefore expedient to provide an adjusting device which allows the user to choose between the control strategies according to curve a or b or which allows the setting of stepless transitions between these two curves, as shown in FIG.



  2 shown in dashed lines, allowed.



  FIG. 2 shows a housing 10 for interior lighting of a refrigeration device, which is suitable for realizing a second embodiment of the present invention. The housing 10 comprises a transparent housing part 11, behind which an illuminant 12, such as a conventional light bulb or halogen bulb, is installed, and an opaque housing part 13, which receives the socket of the illuminant and a control circuit for the electrical power with which the illuminant 12 supplies becomes.

   A light-sensitive element connected to the control circuit is arranged behind a window 14 on a side of the opaque housing part 13 facing away from the illuminant 12, so that light which falls on the light-sensitive element through the window 14 of the housing mounted in a refrigerator is overlaid by the open door of the refrigerator is outside light and light generated by the interior lighting itself and scattered on the walls of the interior and nearby objects.



  The housing 10, together with the components contained therein, forms a structural unit which can be mounted on the inner wall of a refrigeration device with little effort. In particular, a single pair of lines is sufficient for the electrical supply of the entire assembly, which is switched by a door switch such as switch 5, because the control circuit only requires a supply current when the lamp is also in operation.



  A rotary switch 15 for setting the slope of the P / I characteristic curve is mounted on the housing part 13.



  In contrast to the exemplary embodiment described with reference to FIG. 1, where the performance of the interior lighting is controlled in an open circuit, in this configuration regulation takes place in a closed circuit, since the light-sensitive element also detects light generated by the interior lighting itself. This makes it possible to regulate the overall brightness in the interior to a constant value that is independent of the ambient brightness by suitably adjusting the slope of the P / l characteristic curve or to specify the extent of the increase in overall brightness in the interior as the ambient brightness increases.



  Another controller, not shown in the figure, can be provided for setting the P axis section of the P / I characteristic.
