The operation and effects of the drying apparatus for a drum washing machine according to the preferred embodiment of the present invention configured as described above will be briefly described.

When the drying operation is performed in the drum washing machine, first, when the laundry is dried using external air before the heater reaches a predetermined temperature, referring to FIG. 2 again, the first synchronous motor 130 is operated to operate the first washing machine. The valve 120 closes the outlet of the condensation duct 200. At this time, the second synchronous motor 190 operates to close the inlet of the condensation duct 200 while the second valve 180 rotates.

Next, the blower F is operated to suck low-temperature, low-humidity air outside the drum washing machine through the nozzle 110 to pass through the first inlet duct 210 to enter the drum D. At this time, the heater (H) disposed between the first inlet duct 210 and the drum (D) so that the low-temperature, low-humidity external air is in a high-temperature low-humidity state.

Next, the high temperature and low humidity air flowing into the drum (D) absorbs the moisture of the laundry disposed on the drum (D) and changes to a low temperature and humid state to dry the laundry, and the outflow duct coupled to the lower end of the drum (D). It flows out of the drum (D) through the 160. At this time, the air discharged to the outside of the drum washing machine through the outflow duct 160 is changed into a low temperature and humid state and is discharged.

Meanwhile, when the laundry is dried while circulating internal air after the heater H reaches a predetermined temperature, referring to FIG. 3 again, the first synchronous motor 130 is operated to operate the first valve 120 in the nozzle ( The outlet of the 110 is closed and the second synchronous motor 190 is operated to allow the second valve 180 to close the outlet duct 160.

Next, the blower F is operated to suck the low temperature and humid air inside the drum D into the condensation duct 200 through the second inflow duct 170. At this time, the air passing through the condensation duct 200 is in a low temperature and low humidity state in the low temperature and high humidity while passing through the condensation duct 200.

Next, the low temperature and low humidity air flowing into the first inlet duct 210 receives heat from the heater H while passing through the first inlet duct 210 to become a high temperature and low humidity state, and then flows into the drum D. .

The high temperature and low humidity air flowing into the drum (D) absorbs moisture from the laundry, flows out of the drum (D), and circulates again through the second inflow duct (170).

Therefore, the air inside the drum washing machine repeatedly circulates through the drum D, the second inlet duct 170, the condensation duct 200, and the first inlet duct 210, and the high temperature and high humidity, low temperature and low humidity, high temperature low humidity, and high temperature and humidity The laundry disposed on the drum D is dried while repeating one state.

As described above, in the conventional drum washing machine, the air for drying the laundry by circulating the drying device before the heater is heated to a predetermined temperature is a low temperature and low humidity state, so that the drying efficiency of the drying device is low, You spend time. Therefore, the drying apparatus for a drum washing machine according to the present invention dries laundry placed on a drum by sucking external air having a low temperature and low temperature than air circulated inside the drum washing machine before the heater is heated to a predetermined temperature, and the heater reaches a predetermined temperature. Since the laundry is dried by absorbing the moisture of the laundry disposed on the drum until it can improve the drying efficiency of the drying apparatus for the drum washing machine, it is possible to save time spent drying the laundry.
