  • Patent number: 6918194
    Abstract: A heating configuration for a drier, particularly for a laundry drier, has a burner with a burner head, a first heating channel with an inlet opening and an outlet opening, and a second heating channel with an inlet opening and an outlet opening. The cross-sectional area of the second heating channel is greater than the cross-sectional area of the first heating channel. The burner head projects into the inlet opening of the first heating channel and the outlet opening of the first heating channel projects into the inlet opening of the second heating channel. The first heating channel is disposed in the lower section of the second heating channel so that a uniform temperature distribution is achieved in the second heating channel.

  • 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.
