In order to perform a washing process, a user first puts laundry clothes into a drum of a drum washing machine, and then applies a predetermined input to the drum washing machine. A small amount of water is supplied through the dispenser 310 by a controller (not shown) in the drum washing machine. The tub 120 is introduced into the washing process begins.

Then, the steam generator 200 is operated and the high temperature, high pressure steam is introduced into the drum 130 until a predetermined time (a), and starts to call the laundry.

In this case, the temperature in the drum 130 is gradually increased by the supplied steam, as shown in the graph of Figure 6, the temperature is raised to T1.

Thereafter, a small amount of washing water is supplied again through the dispenser 310, and the washing water is circulated by the circulation pump 400 and then drained (hereinafter, referred to as a water supply circulation drainage process).

Thus, during the a-a1 hour on the graph going through the water supply circulation drainage process, since the wash water is made up of the cooling water, the temperature in the drum 130 is lowered.

Then, the steam generator 200 is operated again to supply the generated steam to the drum 130 for a predetermined time (a1-b) to raise the temperature to T2.                     

Then, the water circulation cycle is again performed for a predetermined time (a1-b).

This process is repeated as shown in the graph of Figure 6, iteratively increasing or decreasing the temperature in the drum step by step while performing the washing process while increasing the temperature in the drum to the desired temperature.

In particular, during the washing step that goes through such a process, but in the washing step, water is supplied in a larger amount of washing water than the previous step washing, and the pump is circulated by the circulation pump 400 to finally separate the contaminants from the clothes and discharge the pollution. This is preferred.

It may be made easier, and the washing water that does not contain detergent during the last water circulation cycle in any water circulation drainage step may be supplied with water, so that the washing stroke and a kind of rinsing stroke may be simultaneously performed.

The reason for washing through the above process is that if the steam is continuously supplied for a predetermined time without the process of circulation or water supply, the temperature in the drum may be too high, which may cause damage to clothing of a certain material. By alternately passing the steam supply and feed water circulation draining steps as described above, it is possible to prevent the temperature in the drum from rising too high, and also to gradually increase the temperature, to circulate a small amount of feed water, Since the washing proceeds, the washing water and the electricity consumption can be two.                     

In addition, since a small amount of water is circulated and the washing proceeds, the washing water and the electric consumption can be reduced, and the washing effect is improved by going through a number of soaking processes and the water circulation circulation process.

In particular, in this case, while the steam generator 200 is operated to supply steam, the drum 130 may be operated at a low rotational speed to maximize the dirt removal and soaking effects.

On the other hand, after the washing process is completed, the drying administration is started after the rinsing and dehydration process.

That is, when the drying operation of the drum washing machine starts, power is applied to the drying heater 182 inside the hot air supply pipe 181.

At this time, as the blowing fan 183 and the heater 182 are operated, the blowing fan 183 blows hot air.

The hot air is introduced into the tub 120 by the guide of the hot air supply pipe 181 and is introduced into the drum 130 through a through hole (not shown).

The hot air in the drum 130 heats the laundry to evaporate the moisture contained in the laundry. At this time, the drum 130 rotates at a low speed to stir the laundry, thereby allowing the laundry to be heated evenly, thereby helping to evaporate the moisture. .

The water evaporated in this way is discharged again in a state contained in the air, to remove the moisture of the laundry introduced into the drum (130).

The air thus dried is introduced into the hot air supply pipe 181 again.                     

The laundry is dried while repeatedly performing this series of procedures.

When such a drying process is performed, it is preferable to provide predetermined moisture by using the steam generator, to prevent wrinkles of laundry, etc., and to bring about effects such as static electricity removal.
