Summary of the invention
In order to solve the problems and provide a simple and easy replacement of the light source, the invention provides a slidable cover that in one end position makes the adjustment knob accessible for adjustment and in the other end position makes the light source accessible.
By making the cover slidable, replacement of the light source can be made quickly without the use of screwdrivers or the like, and without detaching the cover. The cover is simply shifted towards the one side, where it is parked during replacement of the light source.
The problem regarding unintentional changes of the refrigerator settings is also solved. In one embodiment of the invention the cover always covers either the adjustment knob or the light source, never both at the same time. This means that when the light source is not covered and illuminating the refrigerator, the adjustment knob is covered thus preventing unintentional changes of the refrigerator settings.
With a construction like this the light source is accessible, when the cover is in one end position. In one position the cover does not block the light from the light source, and thus the refrigerator is illuminated. The cover is covering the adjustment knob in the other end, when it is placed in this position. Since the cover is not securely mounted on the light source holder with screws, locking mechanisms etc., but instead is slidable, the light source is easy to gain access to, when it needs to be replaced. The user of the refrigerator only needs to slide the cover a bit. When the cover has been placed in the end position that makes the light source accessible, the adjustment knob has also been covered by the cover. Therefore the user will not make unintentional changes of the refrigerator settings by pushing the adjustment knob, when the light source is being replaced.
It is also possible to make other aspects of the invention, in which the length of the cover is shorter than the length of the bottom part of the illuminating device. One could make a cover that makes it possible to keep the adjusting knob uncovered by the cover at all times. A smaller cover above the light source can be used to protect the light source only. And the fixation structure could also be made in a way that prevents the cover from covering the adjustment knob. This provides an easy access to the adjustment knob at all times, and when the light source needs to be replaced, the user should slide the cover a bit. In a similar manner it is also possible to make a construction of the cover that always keeps the light source uncovered by the cover. This makes the access to the light source easy at all times, and the user has to slide the cover, if the refrigeration settings should be changed.
Preferably the cover is mounted on the illuminating device using a snap fit mechanism. This makes the mounting of the cover easy and it can be done in different ways. Either the cover can be pressed on until snap fit protrusions snaps into recesses in the fixating structure, or the cover can be slid on the recesses from either side of the illuminating device. It is also possible to mount the cover on the illuminating device by press fitting it onto the fixating structure.
Preferably the cover is longitudinal and has open ends. This is advantageous during the assembling of the illuminating device, because it makes the assembly of the cover to the illuminating device much easier. With the open ends of the cover, it can easily be slid into recesses in the illuminating device. The cover is slidable in the recesses in the fixating structure, when the cover is mounted in them using a snap fit mechanism. The open ends are also advantageous when the mounting of the cover is
done using press fit. It lowers the risk of mounting errors since no end surfaces can be pressed against the illuminating device.
Preferably the adjustment knob is connected to a refrigeration thermostat. The adjustment knob makes it possible to control the temperature with the adjustment knob. It is also possible to connect the adjustment knob to the light source, making control of the light source possible. There are several technologies available for the light source. Preferably a light bulb or light emitting diodes (LED's) are used, and they should be detachable and replaceable.
Preferably the cover has an essentially U-shaped cross section. The cover protects the interior against dirt and humidity. Other forms of the cover is possible. For example rectangular, triangular and arc shapes could be used.
In the preferred embodiment the illuminating device comprises a mounting pad for receiving the means for mounting the illuminating device to the refrigeration appliance. Preferably there is a threaded hole for a screw in the mounting pad. It is also possible to glue the illuminating device onto the refrigeration appliance. Preferably a slidable cover is placed above the mounting pad. This cover can protect the screw against humidity that can lead to rust, but it is also advantageous since it is a switch for the light. The slidable cover is connected to a switch for the light by means of f.x. a spring or a pin. The switch activates the light source, when the refrigerator is open. In this way the cover slide out and covers the screw and protects it, when the refrigerator is open.
In another embodiment of the invention the illuminating device comprises a display for displaying the status of the refrigeration appliance. The parameters in this status includes temperature, humidity and light intensity.
This overview of the status would be advantageous for any user of the refrigeration appliance. It also includes an alarm feature, telling the user if there are any malfunctions in the refrigerator. The display could among several possibilities be a liquid crystal display (LCD) or LED. The display is placed on the bottom of the illuminating device, or on the cover. It could be mounted on the bottom on the illuminating device or cover by fastening means such as screws, rivets, clamps or glue.
In the preferred embodiment the cover is made of plastic, but other materials can also be used. Advantageously, a part of the cover transparent is transparent. The covers can also have many different colours. If the transparent part is in the end near the light source, then the light from the light source is not be blocked when the settings of the refrigeration appliance is changed on the adjustment knob. Thus the settings of the refrigeration appliance can be changed without any disturbance in the light. The described embodiments can be combined to other embodiments.
