  • Drying rack for a laundry dryer
    Patent number: 6915593
    Abstract: A drying rack can be fixed in the drum of a tumble dryer to dispose items to be dried in a static manner. The items can be, for example, woolens or shoes that should not be rotated with the moving drum during the drying process. To prevent the items to be dried from coming into contact with the rotating drum, the drying rack includes an external casing, which seals the rack off from the periphery of the drum. An internal rack, in particular, including several levels, can be located inside the external casing. The items to be dried can be distributed on the levels.
