At the later stage of drying, the water content of the clothes is low, the ambient temperature in the internal circulation is higher, if the difference value between the temperature of a heating source and the temperature of air outlet is smaller than a set threshold T, the dehumidification efficiency is low at the moment, the rotating speed of the first impeller 6 can be properly increased to N3, the clothes are penetrated through by large air quantity, the moisture on the position difficult to dry or fold on the clothes is taken away, the drying uniformity is improved, the clothes at the later stage are basically shaped, the inversion frequency of a drying cylinder can be reduced, the advantages of double impellers are fully exerted, and the air quantity is increased.
Further, the amount of moisture is the amount of water carried away from the clothes when the air passes through the clothes, and the amount of dehumidification is the amount of water converted from condensation of water vapor when the air passes through a condensing device (evaporator, water cooling, etc.), assuming that the relative humidity of the air before entering the clothes is A, the relative humidity after passing through the clothes is B, and the relative humidity after passing through the condensing device is C. The air is generally short in path to the condensing device after passing through clothes, the intermediate loss is less, the relative humidity before entering the condensing device is also equal to B, the moisture carrying capacity is B-A, the dehumidifying capacity is B-C, namely, the numerical values of A and C are compared, and the factors different from the two are mainly the temperature of the air heated by the heating source, the weight of the underwear and the temperature of the condensing device.
