Drying Machine

A drying machine comprising:

• a drum rotatably provided to hold clothes therein;
• a passage to circulate air to enable air exhausted from the drum to be re-supplied to the drum;
• a heater and a circulation fan which are provided in the passage;
• a heat exchanger provided in the passage to exchange heat with the air circulating in the passage and to condense moisture from the air circulating in the passage;
• a moisture absorption unit to absorb moisture from the air circulating in the passage;
• and
• a renewable passage to supply air outside the passage to the moisture absorption unit after passing the heat exchanger.

A drying machine comprising:

• a clothes holding unit to hold clothes therein;
• a drying passage including a heater to supply heated air to the clothes holding unit;
• a dehumidification passage to remove moisture from air exhausted from the clothes holding unit and to supply dehumidified air to the drying passage;
• a heat exchanger to condense moisture from air exhausted from the clothes holding unit;
• a moisture absorption unit including a desiccant to absorb moisture from the air exhausted from the clothes holding unit;
• a circulation fan provided in the drying passage or the dehumidification passage to circulate air;
• and
• a renewable passage to supply heat absorbed from the heat exchanger to the moisture absorption unit to renew the desiccant.
