FIG.

As shown in Figure 4, when the control method of the drum washing machine according to an embodiment of the present invention, the user turns on the power switch, put the laundry into the drum washing machine and then jog dial according to the basic state of the laundry Rotate to select one of the three courses: Standard, Rapid, Quilt Wash, Stinky Wash, Wool, etc. (109).

When the course is selected by the operation mode 109, a predetermined washing time is set in the microcomputer according to the course, and rinsing frequency and time, dehydration intensity and time are sequentially set.

If the preset washing method, the number of rinsing times, and the time required for dehydration are suitable for the user's requirements, and it is determined that a separate time change is unnecessary, the user presses the operation button without inputting the administrative selection button. Accordingly, the washing 121, the rinsing 122, and the dehydration 123 process are sequentially performed during the time required according to the selected washing course, and the washing is completed.

However, if it is determined that the time already set is not appropriate in view of the state of the laundry, for example, it is determined that the amount of the laundry is small, so that it will take less time than the time set in the course corresponding to the laundry, In some cases, it may be determined that more time is required for the soak course.

In this case, when the user selects the stroke by operating the stroke selection button (110), the microcomputer determines which stroke is the selected stroke (111).

However, in this case, the order of stroke selection is preferably made of washing, rinsing, and dehydration. If the stroke selection button is pressed once, the washing stroke is pressed, and the stroke selection button is pressed again without pressing the time addition button or the time reduction button in that state. The rinse stroke is selected, and dehydration is selected by pressing the stroke select button again without changing the time in the rinse stroke selection state.

In addition, when the stroke selection button is pressed again in the dehydration administration selection state, the flow returns to the initial washing administration selection state, and the subsequent processes are the same as the above processes.

For example, if it is determined that the selected administration is the washing administration, and the set time is added (112), the required time of the preset washing administration is changed in the microcomputer, and it is set to the time added than the existing time (113). If it is determined that the set time is input to be reduced (112), the time is set to be reduced than the existing time (114).

Thereafter, if the user determines that it is not necessary to change the set time for the administration other than the washing administration, the user does not need to operate the administration selection button any more, and the microcomputer determines that there is no administration selection, and when the user presses the operation button in that state, After the washing time 121, the rinsing 122, the dehydration 123 to the set time.

However, if the user selects one stroke and adjusts the time, and if it is determined that the time needs to be changed for another stroke, the user must press the stroke selection button again to select the required stroke. It is determined whether there is a selection (110), and it is determined which of these strokes is selected (111).

For example, if it is determined that the dehydration stroke is added after the change of the washing administration time (118), the microcomputer adds or decreases the time as the time is added or decreased. 119, 120).

In addition, this process is equally applicable to the rinsing stroke.

Thus, all the time addition / decrement for the stroke to be changed is made, and if the operation button is pressed without any further administration selection button washing (121), rinsing (122), and dehydration (123) are made for the changed time.

As a specific example of this control method, the user selects 'standard' in the washing course, the 'standard' course is repeated three times, each with 55 minutes of washing time, 10 minutes of rinsing time, and dehydration is set to 7 minutes. Although the degree of contamination or the amount of the laundry is relatively small, the washing machine control will be described when the washing time is 40 minutes, the rinsing time is 5 minutes, and the dehydration time is 3 minutes.

The user first puts laundry into the drum washing machine, and then rotates the jog dial to set the washing course to 'standard'. According to this input, the microcomputer recognizes that the drum washing machine is initially driven three times, each with a washing time of 55 minutes and a rinsing time of 10 minutes, and the dehydration intensity is 'medium' for 7 minutes. The total time required here is 92 Minutes.

However, since the user judged that such a washing course was inadequate in view of the state of the laundry, the user once selected the washing administration by pressing the administration selection button and then pressed the time reduction button 15 times to set the washing time to 40 minutes. When lowered, these results are shown on the display.

In addition, since it is necessary to change the rinsing stroke and the dehydrating stroke in addition to the washing stroke, press the stroke selection button again to select the rinsing stroke, press the time reducing button five times, and then select the dehydrating stroke and enter the time reducing button four times. After pressing the operation button, the washing, rinsing, and dehydration processes are performed for a desired time, and as shown in the above example, the total time is reduced from 92 minutes to 65 minutes.

If it is necessary to increase the time according to the condition of the laundry, it is necessary to select the corresponding stroke by using the administration selection button and operate the time addition button. Can be changed freely.

According to the present invention as described above, by eliminating the inconvenience of having to choose only a few courses and the time according to the microcomputer, by allowing the user to select the required washing time according to the amount of laundry and the degree of contamination, the user Not only can satisfy the demand for time selection of the user, since the washing is completed at the time desired by the user, there is an advantage that a time or energy saving effect can be obtained.
