PURPOSE: To compactly accommodate a 'futon' after drying by installing a heater for heating the air discharged from the air discharge port of a motor- driven blower when a selecting means forms the second air flow passage.

CONSTITUTION: When a knob 13 is set and a motor-driven blower 2 operates, an air passage for the communication between an air suction/discharge port 7 and the air discharge port 20 of the motor-driven blower 2 is formed, and air is taken in from outside through a communication hole 27, and the air is supplied into a 'futon' accommodation bag 14. Further, since an electric current flows in a heater 9 and temperature rises in this state, the dried warm air is supplied into the 'futon' accommodation bag 14, and the dried warm air is blown on a 'futon' 16 in the 'futon' accommodation bag 14. Further, if the motor-driven blower is operated when the first air flow passage is formed by a selecting means, the air in the bag is sucked, and the 'futon' in the bag is compressed by the similar principle to the case of vacuum package.
