The discharge hose 83 may extend out of the cabinet 10. The discharge hose 83 may be connected to a drain pipe separately installed outside the cabinet 10. Therefore, the wet air and condensate of the tub 20 can be discharged to the outside through the discharge hose 83 and the drain pipe.

With this configuration, when the blower fan 55 disposed in the drying duct 50 operates, the wet air in the interior 23 of the tub 20 is connected to the connection chamber of the connection duct 60 through the main connection hose 81 75). The air sucked into the connection chamber 75 may be guided to the drying duct 50 and heated before being circulated into the tub 20 again.

Therefore, the air in the discharge chamber 76 and the air in the suction chamber 77 can exchange heat through the partition wall 78. That is, the high temperature air of the discharge chamber 76 exchanges heat with the air of the relatively low temperature suction chamber 77, so that the air of the discharge chamber 76 is lowered and the temperature of the air of the suction chamber 77 is increased. Can. As a result, the air discharged through the discharge chamber 76 is discharged at a temperature that is not too high, and thus may not cause discomfort to the user, and the air circulated through the suction chamber 77 to the tub 20 is heated to increase in temperature. Energy consumed to reduce energy consumption and drying efficiency may be increased.

A slit 79 may be formed in the partition wall 78 so that heat exchange between the discharge chamber 76 and the suction chamber 77 can be more smoothly performed. Heat can be better exchanged while the air in the discharge chamber 76 and the air in the suction chamber 77 flow through each other through the slit 79.
