Benefits of technology

[0006]According to a first aspect of the present invention, there is provided a door for a cold storage device such as a refrigerator or freezer, comprising a frame and a pane fitted to the frame, characterized by at least one light emitting diode (LED) arranged such that heat generated by the LED(s) during operation of the LED(s) is conducted to the pane to reduce moisture-forming on the pane.
[0007]The invention is based on the understanding that instead of just being lost or otherwise deflected, heat generated by the LEDs can be used for heating the pane to prevent generation of moisture. Preferably, the LEDs are adapted to illuminate the interior of the cold storage device. Thus, no dedicated heating elements are required, which decreases the power consumption. Also, the invention provides for a more compact construction of the door, since the illumination and heating (and optionally grip) functionalities can be integrated.
[0008]In an embodiment the at least one light emitting diode is arranged such that heat generated by the LED(s) during operation of the LED(s) is conducted to the frame and the pane to reduce moisture-forming on the pane.

Problems solved by technology

Thus, no dedicated heating elements are required, which decreases the power consumption.

Embodiment Construction

[0017]FIG. 1 is a partial top view of a door 10 of a cold storage device, such as a refrigerator or freezer, according to an embodiment of the invention. The door 10 comprises a frame 12 to which a pane 14, e.g. a transparent glass or plastics plate, is fitted. The pane 14 makes it possible to inspect the interior of the cold storage device from the outside.

[0018]The door 10 further comprises a plurality of LEDs 16. In FIG. 1, the LEDs 16 are mounted in a reflector profile 18, which in turn is mounted to the frame 12. The reflector profile 18 serves to direct light from the reflector profile 18 as indicated by ray-traces 20. The light is preferably directed towards the interior of the cold storage device, for illumination of the same.

[0019]The reflector profile 18 also serves to conduct heat generated by the LEDs 16 during operation to the frame 12 and on to the pane 14. This is illustrated by arrows 22. To this end, the reflector profile 18 and the frame comprise a heat conducting ...

Abstract

The present invention relates to a door (10) for a cold storage device such as a refrigerator or freezer. The door comprises a frame (12) and a pane (14) fitted to the frame. The door is characterized by at least one light emitting diode (LED) (16) arranged such that heat generated by the LED(s) during operation of the LED(s) is conducted to the pane to reduce moisture-forming on the pane.The present invention also relates to a cold storage device (24), such as a refrigerator or freezer, comprising such a door.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a door for a cold storage device such as a refrigerator or freezer, comprising a frame and a pane fitted to the frame. The present invention also relates to a cold storage device, such as a refrigerator or freezer, comprising such a door.BACKGROUND OF THE INVENTION[0002]Freezer units used in retail are often provided with glass doors so that a customer can see the products in the freezer through the door. However, the temperature difference between the inside of the freezer and the outside tends to cause generation of moisture on such glass doors, obstructing the view through the glass.[0003]One known solution to this problem is to add dedicated heating elements for heating the glass door, whereby the moisture generation is diminished. However, a drawback with this solution is that powering the heating elements requires extra energy, thereby increasing the overall cost of operating the freezer.SUMMARY OF THE INVENTION[0004...
