It can be achieved an advantageous sealing of the usable space without additional, the door in the closing direction incriminating elements. Furthermore, an advantageous second usable space can be achieved below the storage space of the door, in which, for example, baking trays or other accessories can be stored.

If the guide element is arranged at one end of the door, which pivots in the direction of storage space when the door is opened, installation space can be saved and the door can be guided directly into the storage space at its end. However, it is also possible to attach the guide element with a certain distance in front of the end of the door.

If the door can be held in at least one position via at least one holding mechanism, in particular in its closed position, unwanted movement of the door, for example an opening movement in the closed state, can be reliably prevented. The holding mechanism also makes it easy to integrate a child safety lock. In addition to a closed position, the door can be kept on a holding mechanism in further, the skilled person seem appropriate positions, such as in a position in which the door can be advantageously used as a tray and / or drip protection, etc. Furthermore, with the holding mechanism a Operator certain positions of the door are signaled. The operator can thereby move the door quickly and safely to a desired position.

The holding mechanism may be formed by various devices that appear reasonable to those skilled in the art, but particularly advantageously by a latching mechanism, with the structurally simple a comfortable for a user holding mechanism is feasible. The latching mechanism may comprise elastically deformable latching elements or preferably one or more spring-loaded rockers, via which the door in the closed state can advantageously be loaded in its closing direction.

If the pivot axis formed by at least two rolling elements and / or the guide element is formed by a rotatably mounted on the door rolling elements, friction and wear can be reduced and required operating forces can be reduced.

Further advantages emerge from the following description of the drawing. In the drawing, an embodiment of the invention is shown. The drawing, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.
