Clothes tumble dryer and method for controlling the same

摘要

A condenser-type clothes tumble dryer comprising temperature sensor means (5, 6) to detect a temperature difference value between the drying air entering the condenser (4) and the drying air exiting the condenser (4), humidity sensor means (5) to detect a humidity value of the drying air entering the condenser, control means coupled to said humidity sensor means (5), memory means for storing a threshold temperature-difference value (”T TH ) and a threshold relative-humidity value (RH inTH ), which are representative of a pre-determined dryness degree of the load and depend on the particular drying cycle selected by the user, the control means are further adapted to compare said values for switching off said heating means (3) when at least said temperature difference value (”T) reaches up to said threshold temperature-difference value (”T TH ) or at least said relative humidity value (RH in ) reaches down to said threshold relative-humidity value (RH inTH ).
