Referring to Figures 2 and 3, the control method of the combined drum washing machine according to the present invention will be described.

First, the user inputs the object to be washed in the drum 11 and then selects an administrative course to be washed. At this time, it is determined whether a non-stop administrative course is input from the user (S10).

As a result of the determination (S10), when the non-stop stroke course is selected, the amount of washing object put into the drum 11 is first detected (S20).

Then, it is determined whether or not the detected quantity is a quantity capable of non-stop stroke, that is, a predetermined quantity or less (S30).

Here, the set quantity is the amount of cloth defined by a small amount (for example, 1 kg or less), it can be changed according to the type and capacity of the washing machine.

As a result of the determination (S30), if the amount of water currently injected into the drum 11 is less than the set amount, a non-stop stroke is possible, and according to a predetermined administrative condition as a non-stop stroke course regardless of the amount and dryness of the object to be washed. Washing, rinsing, dehydration, drying is performed (S40).

Accordingly, the non-stop stroke of the present invention is a stroke for a small amount of laundry having a set amount or less, omitting the process of determining the amount of dryness or dryness during the stroke and performing the non-stop stroke according to a predefined stroke condition. .

As shown in FIG. 3, when entering the non-stop stroke, water is supplied to a predetermined washing level in the non-stop stroke (S41).

Subsequently, the washing and rinsing process is performed according to a preset time or number of times in a state in which both the periodic detection process and the water level detection and resupply process considering the function of the air are omitted (S42).

When the washing and rinsing stroke is completed, the dehydrating stroke is performed at a predetermined dehydration speed for the first set time (S43).

Subsequently, when the first set time elapses (S44), the dehydration stroke is continued for the second set time while driving the heater 31 (S45).

Therefore, by driving the heater 31 together at a predetermined time point (ie, the time point when the first set time elapses) before the dehydration stroke is completed, the dehydration and drying of the fabric can be simultaneously performed.

Then, when the second set time elapses (S46), the dehydration process is terminated, and drying operation is performed by maintaining the driving of the heater 31 for a predetermined drying time in a state in which the drying degree of the fabric is omitted (step S46). S47).

On the other hand, in the determination result of FIG. 2 (S30), if the quantity in the drum 11 is equal to or larger than the set quantity, it is determined that the non-stop stroke is impossible and displays the state of 'non-stop stroke' (S50).

In addition, on the basis of the amount and dryness of the laundry object currently put in the laundry will be carried out a general administration from drying (S60). In other words, by periodically checking the quantity of the laundry object, washing, rinsing, and dehydrating strokes are carried out according to the quantity. After the dehydration is completed, the heater 31 is driven to determine the dryness of the cloth periodically. While controlling the drying stroke time.

The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, modifications can be made by those skilled in the art to which the invention pertains, and such modifications are within the scope of the present invention.
