Problems solved by technology

[0005] This drying process is very energy-intensive because the heat absorbed by the process air cooling in the heat exchanger is lost whenever this heat is carried away in the cooling air stream

Embodiment Construction

[0029] Such as figure 1The clothes dryer shown comprises a drum rotatable about a horizontal axis, said drum serving as a drying chamber 3 in which an agitator 4 is mounted to move the laundry during the rotation of the drum. Process air is guided by means of a fan 19 over the heating element 18, through the drum 3, the heat exchangers 11, 12 and the heat pumps 13, 14, 15 in the air duct 2 in a closed circuit (process air circuit 2). After passing through the drum 3, the hydrated, hot process air is cooled and, after condensation of the moisture contained in the process air, the process air is reheated. In this case, the air heated by the heating element 18 is guided into the drum 3 from the rear, ie from the side of the drum 3 opposite the dryer door 5, through the perforated bottom, into contact with the laundry to be dried, And flow through the filling port of the drum 3 to reach the lint filter 6 in the dryer door 5 closing the filling port. The flow of air is then turne...

Abstract

The invention relates to a method for operating a condenser tumble dryer (1) with a drying chamber (3) for the objects to be dried, a process air circuit (2), in which a heating element (18) for heating the process air is situated and heated process air is conducted over the items to be dried using a fan (19), a heat pump circuit (13, 14, 15) comprising an evaporator (13), a compressor (14) and acondenser (15), and sensors (22, 23) for determining the humidity in the objects to be dried. In said method, the humidity is determined and the process air is heated by the condenser (15) until a predetermined value (F) for the humidity ranges between 0 % and 12 %.; If the humidity drops below the predetermined value (F), the heating element (18) is activated and operated in such a way that overa period of at least 5 minutes the air temperature in the drying chamber reaches at least 70 DEG C. The invention also relates to a condenser tumble dryer (1) that is particularly suitable for said method.

Description

technical field [0001] The invention relates to a method of operating a condensation tumble dryer comprising a drying chamber for items to be dried; a process air circuit in which a device for heating the process air is arranged A heating element and said heated air is directed over the item to be dried by means of a fan; a heat pump circuit comprising an evaporator, a compressor and a condenser; and a sensor for detecting the humidity of the item to be dried, the present invention It also relates to a condensation tumble dryer suitable for the method. The method is suitable for the disinfection of objects, especially laundry. Background technique [0002] The working principle of a tumble dryer is based on the process air discharged from the clothes condensing the moisture evaporated from the clothes by the warm process air, such tumble dryers are also called condensation dryers, which do not require a vent hose and Very popular because it can be used in interior bathroom...
