Abstract
Method and device of automatically controlling the drying process of a laundry drying system until a given desired degree of dryness is reached, including heating means, a drive for the drying system, a control device for controlling the drive and heating means, and means for supplying system-related fixed data concerning the drying of particular laundry, which includes determining the gradient of rising temperature in the drying system during a given early phase of the drying process, calculating a required operating time for the heating means and the drive from the determined gradient and the system-related fixed data, and feeding the calculated operating time as an input to the control device.

Method of automatically controlling the drying process of a laundry drying system until a given desired degree of dryness is reached, including heating means, a drive for the drying system, a control device for controlling the drive and heating means, and means for supplying system-related fixed data concerning the drying of particular laundry, which comprises determining the gradient of rising air temperature leaving the drying system during a given early phase of the drying process, calculating a required operating time for the heating means and the drive from the determined gradient and the system-related fixed data, and feeding the calculated operating time as an input to the control device.
Device for performing a method of automatically controlling the drying process of a laundry drying system until a given desired degree of dryness is reached, comprising heating means, a drive for the drying system, a process control unit connected to said heating means and drive for controlling the drying process, means for supplying system-related fixed data concerning the drying of particular laundry, means for determining the gradient of rising air temperature leaving the drying system during a given early phase of the drying process, and a computing unit including said temperature gradient determining means and being connected to said fixed data supplying means and said process control unit for calculating a required operating time for said heating means and drive from the determined gradient and the system-related fixed data and feeding the calculated operating time as an input to said process control unit.
