steam generating means 100 during the drying process of the air may become smaller and hence there may be no big trouble in drying laundry thus the air intake valve or the steam valve is not necessarily required although the blower 210 illustrated in fig5 employs the method of sucking air or steam by rotating wings the present invention is not necessarily limited thereto and any means capable of sucking air and steam such as a gear pump and a piston pump can be applied without any limitation further although the heat supplier 220 may be a hot wire type as illustrated in fig5 the present invention is not limited thereto and a heat pump or any other means capable of removing moisture by heating air can be applied if there is a means capable of removing moisture from air by a chemical method this means can replace the heat supplier 220 thus it is not necessary to essentially provide the heat supplier 220 hereinafter a procedure for heating steam supplied from the steam generating means through the dryer 200 will be described first as the blower 210 rotates this lowers the pressure at the steam valve 250 side at this time if the air intake valve 240 is closed and the steam valve 250 is opened steam is introduced through the steam valve 250 because no air is introduced from the air intake valve 240 the introduced air passes through the heat supplier and is heated by receiving heat at this time to sufficiently raise the temperature of the steam it is possible to use a means for increasing the opportunity to receive heat from the heat supplier 220 by making the length of the drying duct 230.
