The present invention relates to a drum washing machine, and more particularly, to a drum washing machine driving control method to skip the stroke according to the selection to reduce the time required for washing.

In general, the low-type washing machine performs a washing operation to agitate the laundry immersed in the wash water in the reservoir through the rotational drive of the pulsator, while the drum washing machine to perform the washing operation by rotating the drum in which the laundry is put horizontally do. Therefore, the drum washing machine has a mechanical structure different from that of a general water washing machine.

Referring to the operation of the drum washing machine, first, when the user puts laundry into the drum and turns on the start switch, the microcomputer detects the weight of the laundry put into the drum, determines the amount of water suitable for the weight of the laundry, and starts water supply.

When the water supply proceeds to the water level set in the water tank surrounding the drum, the drum rotates according to the driving of the driving motor, and washing is performed by the drop of laundry. This washing proceeds for a time set by the weight of the laundry.

After the washing stroke is completed, the dehydration stroke is executed at the same time as the drainage operation of discharging the contaminated washing water of the reservoir to the outside by the drain valve, and the water is supplied again a predetermined number of times, and the washing stroke is repeated for a predetermined number of times. In addition, when the washing administration is completed, the rinsing stroke and the dehydration stroke are subsequently performed.

Such washing administration, rinsing administration, and dehydration administration usually require a user to put laundry into a drum and enter a washing key, and according to the weight of the laundry, washing administration, rinsing administration, and dehydration administration according to a pre-stored administrative sequence. Or it will be automatically executed by administrative recovery.

In addition, even in the heating washing, the temperature of the washing water is automatically set, the washing water is heated to this set temperature, and then the washing administration is performed.

However, in the point that washing is automatically executed, it may provide convenience to the user. However, since all strokes are performed according to a predetermined order, there is a disadvantage in that it takes a lot of time.

In particular, in the case of the heating washing in winter, when the washing water temperature is set to 90 ℃ heating time takes too much, there was a problem that the overall washing time is very long.

SUMMARY OF THE INVENTION The present invention has been made to improve the above-described problem, and has an object of reducing the time required for washing by skipping the current administration according to the user's selection and performing the next administration.

The configuration of the present invention, which is invented to achieve the above-described object, is as follows. In the drum washing machine driving control method of the present invention, when the washing start instruction is input, the drum washing machine driving control method for washing the laundry at a predetermined stroke time and stroke times according to a predetermined stroke sequence, When a skip key signal for skipping is input, the current stroke is skipped and the next stroke of the skipped stroke is performed, but if the current stroke is a rinsing stroke, only the rinsing stroke is skipped once, and the currently ongoing stroke is skipped. When the rinsing stroke is the last number of times, the rinsing stroke is skipped and the draining process is performed.

Drum washing machine driving device according to another embodiment of the present invention washing machine microcomputer 110, temperature sensor 120, memory unit 130, heating device 140, key input unit 150, water supply valve 160, A drain valve 170 and a drive motor 180 are provided.

First, the temperature sensor 120 senses the temperature of the wash water and outputs it to the microcomputer 110, and the memory unit 130 stores various programs and data necessary for driving the drum washing machine.

The heating device 140 heats the washing water during a heating washing so that washing can be performed at a predetermined heating temperature, for example, 30 ° C., 40 ° C., 60 ° C., and 90 ° C., or by heating air during a drying stroke. To be fed into the drum.

The key input unit 150 includes a skip key 152 for outputting a key signal of a key selected by the user to the microcomputer 110 so as to skip the current stroke.

The water supply valve 160 is turned on / off according to the control signal of the microcomputer 110 to supply the washing water to the drum, and the drain valve 170 is turned on / off according to the control signal of the microcomputer 110 so that the drum The wash water to the outside.

Finally, the drive motor 180 is to rotate the drum in accordance with the control signal of the microcomputer 110, the drum rotational speed is preset for each course washing and each stroke to rotate the drum according to this rotational speed.

Lastly, the microcomputer 110 controls the drum washing machine driving control method according to an embodiment of the present invention. When the skip key signal is input during washing, the microcomputer 110 skips the current stroke and performs the next stroke. do.

In the drum washing machine driving control method according to an embodiment of the present invention, if the first user inputs laundry start signal through the key input unit 150 after the laundry is put into the drum, the microcomputer 110 may store the memory unit according to the weight of the laundry. After reading the predetermined stroke, time, number of strokes, etc. from 130, washing is started according to this data (S10).

After commencement of washing, the microcomputer 110 determines whether a skip key signal is input from the skip key 152 of the key input unit 150 (S20). If the skip key signal is input at this time, the current stroke is suspended (S30). And proceed to the next administration (S40).

As described above, stopping the current stroke and executing the next stroke upon inputting the skip key signal will be described with reference to FIGS. 3 and 4.

3 and 4 illustrate a washing machine that takes a relatively long time during washing.

First, referring to the washing order of the heating washing, the washing water supplied through the water supply valve 160 to heat the washing water temperature to any one of the first preset heating temperature, for example, 30 ℃, 40 ℃, 60 ℃, 90 ℃ The water is heated using the heating device (140).

Along with this, the temperature of the washing water is sensed through the temperature sensor 120, and when the detected washing water temperature reaches a set heating temperature, the driving motor 180 is driven to rotate the drum, thereby washing the washing operation. To perform.

When the main washing is completed, the washing water in the drum is drained through the drain valve 170, and when the draining is completed, the driving motor 180 is rotated at a predetermined revolution (pervolutions per minute) to wash the washing water permeating the laundry. Perform an intermediate dehydration process to dehydrate.

After the intermediate dewatering, the washing water is supplied through the water supply valve 160 and the driving motor 180 is rotated at a predetermined rpm to rinse.

Here, the intermediate dehydration, water supply and rinsing process are referred to as rinsing stroke.

This rinsing stroke is not limited to three times but is usually repeated three times, and may be variously set according to the weight of laundry. The number of rinsing cycles in this embodiment is three times.

When the rinsing cycle is performed three times in this way, the washing water in the drum is drained through the drain valve 170, and the driving motor 180 is rotated at a high speed to dehydrate the washing water that oozes into the laundry. Perform the administration.

Various programs and the like necessary for this washing process are stored in the memory unit 130.

In the heating laundry, when the user inputs the skip key 152 of the key input unit 150, the skip key signal is input, that is, the current stroke is skipped. FIG. 3 shows the main laundry, that is, the washing administration. As the main laundry is in progress, a skip key is input to stop the main laundry and the draining process is performed.

On the other hand, Figure 4 shows that skipping the rinsing stroke, since the rinsing stroke is normally repeated n times, if the skip key is input, the number of rinsing strokes are skipped once without skipping the whole rinsing stroke.

Therefore, no intermediate dewatering, watering, and rinsing procedures are performed once.

In addition, if the current rinsing administration is the last number of times, the drainage process is performed.

That is, the drum washing machine driving control method of the present invention can reduce the washing time required for washing by skipping the current stroke according to the user's selection.
