A driving motor 71 for driving the drum 30 is provided and a blowing fan 83 for forced circulation of air is provided on the air discharge side of the hot air supply duct 81.

Accordingly, when the laundry is dried, hot air generated by the drying heater 82 and the blowing fan 83 is supplied into the drum 30 to dry the laundry.

With the above arrangement, the contaminated washing water remaining in the gasket 50 can be evaporated and removed after completion of the washing machine operation course such as washing, rinsing, and dewatering without addition of a separate apparatus.

On the other hand, after the driving course of the washing machine is completed, the laundry may be dried as it is in the drum type washing machine 1 for drying and drying. However, when the laundry is taken out from the drying type combined drum washing machine 1 and dried outside (for example, And dried in the same place by exposure to sunlight), the laundry in the dehydrated state is taken out without performing a drying step and dried.

In addition, after the laundry is drawn out from the outside of the drying and combining drum washing machine 1, the power of the drum washing machine is turned off, thereby preventing waste of electric power.

2, the method for removing moisture in the gasket 50 according to the first embodiment of the present invention includes a selection step S10 for selecting a drying cycle, a step S20 for selecting whether to remove moisture from the gasket 50, (Step S30).

First, when the user turns on the power of the dry type combined drum washing machine 1 and selects a general driving course, that is, washing, rinsing and dewatering, each stroke is performed sequentially.

After completion of the dewatering step of the laundry, the drying step of selecting the drying step (S10) is carried out. In this step (S10), there are two following processes that the user can select. That is, the laundry is dried at the outside of the washing machine 1 by selecting the drying cycle of the laundry or taking out the laundry after dehydration.

When the user selects the drying cycle of the laundry in the drying cycle selection step (S10), drying of the dehydrated laundry is performed using the hot air supplied into the drum (30).

Here, when the drying cycle is completed, all the driving courses are completed when the power to the washing and drying drum washing machine 1 is turned off and the dried laundry is taken out of the drum 30.

However, if the user takes out the dehydrated laundry without selecting a drying stroke, the step S20 of selecting whether to remove the moisture of the gasket 50 is performed.

If the user selects to remove moisture in the step S20 of selecting whether to remove moisture in the gasket 50, the moisture removing step S30 of the gasket 50 is performed.

As shown in Fig. 3, the case where the drying cycle is selected in the drying cycle selection step S11 is the same as that in the first embodiment of the present invention shown in Fig.

However, if the user does not select a drying stroke, a gasket 50 including a step S21 of detecting whether or not there is laundry in the drum 30 and a step S31 of sensing whether the door 40 is closed, And a moisture removing step S41 of the gasket 50 are performed.

First, when it is determined that there is laundry in the drum 30, the drying step S11 is performed again.

If it is determined that there is no laundry in the drum 30, a step S31 is performed to detect whether the door 40 is closed. If it is determined in step S31 that the door 40 is opened, The same step S31 is performed again.

If it is determined in step S31 that the door 40 is closed, the moisture removing step S41 of the gasket 50 is performed. This step S41 is performed by supplying the hot air heated by the drying heater 82 to the inside of the drum 30 through the hot air supply duct 81 for a certain period of time.

When the moisture removal step (S41) of the gasket (50) is completed, the door (40) is opened and the power of the dry type combined drum washing machine (1) is turned off. At this time, the doors 40 are opened after the moisture in the gasket 50 is removed. The hot air remaining in the drum 30 is removed.

In order to automatically open the door 40 after the gasket 50 is completely removed from the moisture, an electromagnet member (not shown) operatively associated with a power source supplied to the drying and combining drum washing machine 1 is connected to the periphery of the inlet 11 .

That is, when the power source of the dry type combined drum washing machine 1 is turned off, the electromagnet member may lose magnetism, and at the same time, the door 40 may be opened by coming out from the surface of the inlet 11.

If it is determined that the laundry is present in the drum 30, the step of selecting the drying cycle (S21) is not performed once, but the step of taking out the laundry is performed by the user. After the laundry is taken out, A step S22 of detecting whether laundry is present is performed. At this time, after the laundry is taken out of the drum 30, the step S32 of detecting whether the door 40 is closed is performed without performing the step S22 of detecting whether laundry is present in the drum 30 It is possible.

In this case, the drawn laundry should not be dried in the dry-type drum washing machine 1 but should be exposed to sunlight in a place such as a rooftop.

If it is determined that there is no laundry in the drum 30, a step S32 is performed to detect whether the door 40 is closed. If it is determined in step S32 that the door 40 is opened, And the same step S32 is performed again.

The subsequent steps in which the door 40 is closed in the door closing determination step S32 are the same as those in the second embodiment of the present invention shown in FIG. 3, so that a description thereof will be omitted.

That is, the difference between the second embodiment and the third embodiment of the present invention is that when the laundry is present in the drum 30, the laundry is taken out and dried outside the drum-type washing and drying machine 1, (1) by using a drying process.
