  • Patent number: 10941514
    Abstract: A drying apparatus according to the present invention and a laundry drying machine including the same circulate only some of humid air introduced from a drum and discharge the remaining humid air through a discharge port, and then introduce mixed air, in which external air introduced through an introduction port and circulated humid air are mixed, into the drying duct to supply the air to the drum. Accordingly, since air in which there is little moisture may be circulated, drying performance of the drying apparatus may be improved. Further, by disposing an introduction fan or a discharge fan adjacent to the discharge port and mixing the humid air with the external air, since the air of which the moisture amount is little may be discharged to the outside of a cabinet, or the air discharged through the discharge port may be quickly discharged to the outside of the cabinet by the discharge fan, occurrence of dew condensation in the cabinet may be prevented.
