First, the washing function will be described as follows. The washing function is substantially the same as the operation of a conventional washing machine. That is, the washing stroke, the rinsing stroke and the dehydrating stroke are sequentially performed to wash the laundry.

The drying process begins when washing and dehydration are complete. When the drying process is started, the air of the inner tank 5 is introduced into the circulation duct 20 by the blowing fan 22, heated by the heater 15 to be in a high temperature state, and supplied to the inner tank 5. Heated air supplied to the inner tank (5) heats the laundry to dry the laundry, the temperature is relatively low and the humidity is increased.

If such humid air is circulated in such a state, the drying efficiency is lowered. Therefore, moisture contained in the air should be removed during the air circulation. That is, the outside air of relatively low temperature is supplied to the inside of the washing machine through the outside air supply duct 60 by the outside air fan 62. The supplied outside air is heat-exchanged while passing through the cooling fins 24 of the circulation duct 20, and thus dehumidification is performed in humid air flowing in the circulation duct 20.

Then, the water flows down along the inner wall of the circulation duct 20 and exchanges heat with humid air circulating in the circulation duct 20 to condense water vapor contained in the air. At this time, the water supplied from the outside is also provided to the outer cover 50 through the water supply auxiliary duct (42). The water provided in the outer tub cover 50 is provided to the wall surface of the outer tub 3 through the sprinkler 58 so that dehumidification is performed in the same principle.

Meanwhile, the water dehumidified by the dehumidifying action in the circulation duct 20 and the outer tub 3, that is, the condensed water, is discharged to the outside of the washing machine via the outer tub 3 and the drain duct 11. The dehumidified and relatively low humidity air is heated by the heater 15 and supplied to the inner tank 5 again.

As described above, the heated air circulates the inner tank 5 to dry the laundry in the inner tank 5, and the drying process is completed after a predetermined time cycle.

The present invention has been described above only one embodiment, but as can be seen in the appended claims, those skilled in the art to which the present invention pertains may be modified without departing from the spirit of the present invention. It will be understood that it belongs to the scope of the invention.
