Abstract:
1. A refrigerator and/or freezer unit comprising: a door; an apparatus for detecting a position of the door, the apparatus having a magnet, a sensing element responsive to a magnetic field generated by the magnet, and a ferromagnetic material; and a movable slider rail arranged at a carcass of the unit and configured to move substantially horizontally in dependence on the position of the door, wherein the magnet, the sensing element, and the ferromagnetic material are positioned such that different states of the sensing element are generated in dependence on a position of the magnet, the sensing element, and the ferromagnetic material with respect to one another; wherein the magnet and the sensing element are arranged stationary on the carcass of the unit and the ferromagnetic material is disposed on the slider rail and is movably actuated by the door, such that the ferromagnetic material is removed from between the magnet and the sensing element when the door is open, and extends between the magnet and the sensing element when the door is in a closed position, and wherein the slider rail is spring-loaded, with a spring coupled between the slider rail and the carcass, such that the ferromagnetic material is removed from between the magnet and the sensing element with lack of influencing by the door of the unit.
