Abstract
Abstract A bed clothes drying device comprises a hot air supplier having a blower and a heater which is connected to an air inlet and a hot air outlet and a bag which is connected through a joint pipe to the hot air outlet and filled out under a blow pressure given by feeding a hot air from the hot air supplier to discharge the hot air through the sheet of the bag and which has flexibility and air-permeability with a resistance of 1.75 to 3.75 mmH 2 O to air flow of 0.7 to 1 m 3 /min. The bag is disposed between a bed and a coverlet to dry the bed and the coverlet with the hot air and the bag has an improved structure.
