Washing and drying integrated machine

The invention discloses a washing and drying integrated machine which comprises a washing barrel, a heating air duct, a drying draught fan, a condenser, an optical detecting device and a controller. One side of the heating air duct is communicated with the washing barrel. A heater is arranged in the heating air duct. One side of the condenser is communicated with the washing barrel. The other side of the condenser is communicated with the other side of the heating air duct through the drying draught fan. The condenser comprises a transparent detecting part. The optical detecting device is arranged on the outer surface of the transparent detecting part and used for emitting light rays to the transparent detecting part and receiving reflected light rays of the transparent detecting part to obtain clothes drying detection signals. The controller is connected with the optical detecting device and used for judging the drying level according to the clothes drying detection signals and conducting drying control according to the drying level and a preset drying level. The washing and drying integrated machine can judge the clothes drying degree and is instantly stopped when drying is completed, and control accuracy is improved.
