본 발명은 드럼 세탁기의 탈수운전 제어방법에 관한 것으로서, 보다 상세하게는 드럼 세탁기의 탈수운전 중 본탈수시 세탁조의 수위를 측정하여 급수호스의 불량으로 인한 이상급수로 인해 탈수이상이 발생할 경우 정확한 원인을 표시하고 탈수운전을 중지시킬 수 있도록 한 드럼 세탁기의 탈수운전 제어방법에 관한 것이다. The present invention relates to a method for controlling the dehydration operation of a drum washing machine, and more particularly, the exact cause when dehydration abnormality occurs due to an abnormal water supply due to a poor water supply hose by measuring the level of the washing tank during the main dehydration during the dehydration operation of the drum washing machine. It relates to a dehydration operation control method of the drum washing machine to display and stop the dehydration operation.

일반적으로 수직축 상에서 세탁조를 회전시키는 저수조형 세탁기가 펄세이터의 회전구동을 통하여 저수조 내의 세탁수에 잠겨진 세탁물을 교반 세탁하는 것과는 달리 드럼형 세탁기는 세탁물이 투입된 드럼을 수평회전시키는 동작으로 세탁물을 이동시킨 후 떨어지는 낙차력과 회전하는 드럼과 세탁물간의 마찰을 이용하여 세탁하는 것으로 세탁물의 손상이 거의 없고 세탁물이 서로 엉키지 않으며 두드리고 비벼 빠는 세탁효과가 있다. In general, unlike the water-type washing machine which rotates the washing tank on the vertical axis, the washing machine is agitated to wash the laundry immersed in the washing water in the water tank by rotating the pulsator, and the drum-type washing machine moves the laundry by rotating the drum in which the laundry is inserted. After washing by using the falling power of falling and the friction between the rotating drum and the laundry, there is almost no damage to the laundry and the laundry is not tangled with each other, there is a laundry effect of pounding and scuffing.

도 1은 일반적인 드럼세탁기를 개략적으로 나타낸 단면도이다. 1 is a cross-sectional view schematically showing a general drum washing machine.

여기에 도시된 바와 같이 세탁물(14)을 장입하고 있는 드럼(11) 둘레의 저수조(10)에는 일정수준까지의 수위(15)로 급수되어진 상태를 보이고 있다. 여기에서는, 드럼(11)이 회전하면 세탁수에 잠겨있던 세탁물(14)이 리프터(12)에 걸려 윗쪽으로 이동한 후 일정위치에 이르게 되면 자중에 의해 낙차되게 되며 이때의 낙차력 으로 세탁이 이루어지도록 하고 있다.As shown here, the reservoir 10 around the drum 11, which is loaded with the laundry 14, shows a state in which water is supplied to the water level 15 up to a predetermined level. In this case, when the drum 11 rotates, the laundry 14, which is locked in the wash water, is caught by the lifter 12, moves upward, and reaches a predetermined position. To lose.

또한, 드럼(11) 하부에는 세탁수를 가열하기 위한 세탁히터(13)가 설치되어 삶아 빠는 세탁효과를 얻을 수 있도록 하고 있다. In addition, a washing heater 13 for heating the washing water is installed at the lower part of the drum 11 so as to obtain a washing effect of boiling.

도 2는 일반적인 드럼세탁기의 제어회로를 나타낸 블록구성도이다. 2 is a block diagram showing a control circuit of a general drum washing machine.

여기에 도시된 바와 같이 드럼(11) 내에 장입된 세탁물(14)의 중량값을 측정하기 위한 로드셀센서(21)와, 저수조(10) 내의 세탁수의 수위를 감지하기 위한 수위센서(29)와, 로드셀센서(21)와 수위센서(29)의 값을 입력받아 드럼세탁기의 전체동작을 제어하기 위한 마이컴(20)과, 마이컴(20)의 급수 제어신호에 따라 급수밸브의 작동을 제어하기 위한 급수제어부(22)와, 마이컴(20)의 배수 제어신호에 따라 배수밸브(25)와 배수모터(26)의 작동을 제어하기 위한 배수제어부(24)와, 마이컴(20)의 모터 제어신호에 따라 드럼(11)을 회전시키기 위한 모터(28)의 작동을 제어하기 위한 모터구동제어부(27)와, 마이컴(20)의 제어신호에 따라 세탁수를 가열하기 위한 세탁히터(13)로 이루어진다. As shown here, the load cell sensor 21 for measuring the weight value of the laundry 14 loaded in the drum 11, the water level sensor 29 for detecting the water level of the wash water in the reservoir 10 and For receiving the values of the load cell sensor 21 and the water level sensor 29, the microcomputer 20 for controlling the overall operation of the drum washing machine and the water supply control signal of the microcomputer 20 for controlling the operation of the water supply valve. In response to the water supply control unit 22, the drain control unit 24 for controlling the operation of the drain valve 25 and the drain motor 26 in accordance with the drain control signal of the microcomputer 20, and the motor control signal of the microcomputer 20 Accordingly, the motor driving control unit 27 for controlling the operation of the motor 28 for rotating the drum 11, and the laundry heater 13 for heating the wash water in accordance with the control signal of the microcomputer 20.

이와 같이 구성된 드럼세탁기의 동작을 설명하면 다음과 같다. Referring to the operation of the drum washing machine configured as described above are as follows.

먼저, 드럼세탁기의 도어를 열고 세탁물을 투입한 후 세탁운전 스타트 스위치를 온 시키면 드럼(11) 내에 투입된 세탁물(14)의 중량을 로드셀센서(21)에 의해 검출된다. 이렇게 로드셀센서(21)에 의해 검출된 세탁물의 중량은 마이컴(20)에 입력된다.First, when the door of the drum washing machine is opened and the laundry is put in and the washing operation start switch is turned on, the load cell sensor 21 detects the weight of the laundry 14 put into the drum 11. The weight of the laundry detected by the load cell sensor 21 is input to the microcomputer 20.

이에 따라 마이컴(20)은 메모리 테이블을 참조하여 급수량을 결정하고 급수제어부(22)에 제어명령을 출력하여 급수밸브(23)가 열려지도록 함으로써 급수가 시 작된다. 이렇게 급수가 진행되면 저수조(20)의 일측에 마련된 수위센서(29)에 의해 수위를 모니터링하여 그 검출수위값을 마이컴(20)에 제공한다. 그러면, 마이컴(20)은 입력되는 수위센서(29)로부터의 검출수위값을 통해 설정된 수위값에 도달하였는지 여부를 판단하여 검출수위값이 설정수위값에 도달하였으면 급수제어부(22)를 통해 급수밸브(23)를 차단하여 급수를 중단시킨다.Accordingly, the microcomputer 20 determines the water supply amount by referring to the memory table and outputs a control command to the water supply control unit 22 so that the water supply valve 23 is opened to start the water supply. When the water supply proceeds as described above, the water level is monitored by the water level sensor 29 provided at one side of the reservoir 20, and the detected water level value is provided to the microcomputer 20. Then, the microcomputer 20 determines whether the set water level value is reached based on the detected water level value from the input water level sensor 29. When the detected water level value reaches the set water level value, the water supply valve 22 supplies the water supply valve. Shut off (23) to stop water supply.

이렇게 드럼세탁기의 저수조(20)에 세탁물(14)에 대응하는 적정량의 세탁수가 저수 완료되고 나면 마이컴(20)은 내부의 세탁운전 프로그램에 따라 모터구동제어부(27)에 제어신호를 출력하여 모터(28)를 회전구동 시킨다. After the appropriate amount of washing water corresponding to the laundry 14 is stored in the water storage tank 20 of the drum washing machine, the microcomputer 20 outputs a control signal to the motor driving control unit 27 according to the internal washing operation program to supply the motor ( Rotate 28).

모터(28)가 회전 구동하면 저수조(20)내의 세탁 드럼(11)도 따라서 회전하게 되며 드럼(11) 내부의 리프터(12)에 의한 세탁물의 순차이동 및 낙차를 이용한 드럼세탁이 실행되게 된다.When the motor 28 is driven to rotate, the washing drum 11 in the reservoir 20 also rotates accordingly, and the drum washing using the sequential movement and washing of the laundry by the lifter 12 inside the drum 11 is performed.

이와 같이 세탁운전을 완료한 후에는 세탁물(14)에 포함된 세탁수를 제거하기 드럼(11)을 고속회전시켜 원심력에 의한 세탁물(14)에 포함된 세탁수를 제거하는 탈수운전을 수행하게 된다. After the washing operation is completed as described above, the drum 11 is rotated at a high speed to remove the washing water contained in the laundry 14, and the dehydration operation of removing the washing water contained in the laundry 14 by centrifugal force is performed. .

이렇게 탈수되는 물은 드럼(11) 원주벽에 형성된 수많은 미세한 구멍을 통해 저수조(20)로 빠져나오면 배수밸브(25)와 배수모터(26)가 작동되어 밖으로 배수된다. The dewatered water is discharged to the reservoir 20 through a number of fine holes formed in the circumferential wall of the drum 11 so that the drain valve 25 and the drain motor 26 are drained out.

그러나, 탈수운전을 수행하면서 세탁수가 정상적으로 배수되지 않거나 급수호스의 불량으로 이상급수가 발생할 경우 세탁수가 드럼의 회전을 방해함에 따라 과부하가 발생하여 탈수운전이 중지되고 에러를 표시하게 된다. However, if the wash water is not drained normally during the dehydration operation or abnormal water supply occurs due to a poor water supply hose, an overload occurs as the wash water interferes with the rotation of the drum, and the dewatering operation is stopped and an error is displayed.

그런데, 이때 발생되는 에러는 단순히 배수펌프에 이상이 있다는 에러로만 표시되기 때문에 정확한 원인을 용이하게 파악할 수 없는 문제점이 있다. However, the error generated at this time is simply displayed as an error that there is an error in the drainage pump, so there is a problem in that the exact cause cannot be easily grasped.

본 발명은 상기와 같은 문제점을 해결하기 위해 창작된 것으로서, 본 발명의 목적은 드럼 세탁기의 탈수운전 중 본탈수시 세탁조의 수위를 측정하여 급수호스의 불량으로 인한 이상급수로 인해 탈수이상이 발생할 경우 정확한 원인을 표시하고 탈수운전을 중지시킬 수 있도록 한 드럼 세탁기의 탈수운전 제어방법을 제공함에 있다. The present invention was created to solve the above problems, an object of the present invention is to measure the water level of the washing tank during the dehydration operation during the dehydration operation of the drum washing machine when the dehydration abnormality due to the abnormal water supply due to the poor water supply hose The present invention provides a method of controlling the dehydration operation of a drum washing machine to display the exact cause and to stop the dehydration operation.

상기와 같은 목적을 이루기 위한 본 발명은 드럼 세탁기에 있어서 밸런스 탈수를 수행한 후 본탈수를 수행하는 드럼 세탁기의 탈수운전 제어방법에 있어서, 밸런스 탈수를 수행한 후 본탈수시 현재 RPM과 목표 RPM의 RPM 편차를 측정하는 단계와, RPM 편차를 측정하여 일정값 이상 차이가 발행할 경우 세탁수위를 측정하는 단계와, 세탁수위를 측정하여 일정수위 이상일 경우 에러 메시지를 표시하고 탈수를 정지시키며 일정수위 미만일 경우 밸런스 탈수를 수행하는 단계를 포함하여 이루어진 것을 특징으로 한다. In order to achieve the above object, the present invention provides a method for controlling dehydration operation of a drum washing machine that performs dehydration after performing a balance dehydration in a drum washing machine. Measuring the deviation of the RPM, Measuring the deviation of the RPM measuring the water level when the difference is more than a certain value, and measuring the washing water level, if the water level is above a certain level to display an error message and stop dehydration In the case characterized by comprising a step of performing a balance dehydration.

본 발명에서 RPM 편차는 70 RPM인 것을 특징으로 한다. RPM deviation in the present invention is characterized in that 70 RPM.

본 발명에서 일정수위 이상으로 에러를 표시할 때 급수호스 불량으로 표시하 는 것을 특징으로 한다. In the present invention, when the error is displayed above a certain level, it is characterized by displaying as a water supply hose failure.

이와 같이 이루어진 본 발명은 드럼 세탁기의 탈수운전시 본탈수를 진행하면서 현재 RPM이 목표 RPM에 도달하지 못할 경우 세탁수위를 측정하여 급수가 이루어지고 있는지 판단하여 일정수위 이상의 수위가 측정될 경우 계속해서 급수가 이루어지고 있는 것으로 판단하여 급수호스 불량을 표시할 뿐만 아니라 탈수운전을 중지시켜 탈수운전에서의 이상원인을 정확하게 판단할 수 있도록 한다. The present invention made as described above proceeds with the main dehydration during the dehydration operation of the drum washing machine, if the current RPM does not reach the target RPM to determine whether the water supply is made by measuring the washing water level if the water level above a certain level is continuously measured In addition, it indicates that the water supply hose is defective and stops the dehydration operation so that the cause of abnormality in the dehydration operation can be accurately determined.

도 3은 본 발명에 의한 드럼 세탁기의 탈수운전 제어방법을 설명하기 위한 흐름도이다. 3 is a flowchart illustrating a dehydration operation control method of a drum washing machine according to the present invention.

먼저, 세탁운전 및 헹굼운전을 마친 후 탈수운전을 수행하게 되면 밸런스 탈수를 수행하여 세탁물을 좌우 교반운전을 통해 뭉쳐있는 포를 펼친 후 일정한 속도로 회전시켜 포를 드럼 내벽에 골고루 붙여 가속하여 밸런스를 판단하게 된다(S10). First, when dehydration operation is performed after washing and rinsing operation, balance dehydration is performed to spread the laundry through the left and right stirring operation, and then rotate the cloth at a constant speed to accelerate the balance evenly by attaching the cloth to the inner wall of the drum. It is determined (S10).

이때 밸런스가 맞지 않을 경우에는 밸런스 탈수를 반복 수행하게 된다(S12). If the balance is not correct at this time, the balance dehydration is repeated (S12).

이렇게 밸런스 탈수를 수행하여 밸런스를 맞춘 후 본탈수를 수행하게 된다 (S14). After performing balance dehydration as described above, the balance is performed (S14).

본탈수를 수행하면서 현재 RPM을 측정하여 목표 RPM과 현재 RPM의 RPM 편차를 판단하게 된다(S16). 이때 약 70RPM 정도의 편차가 발생하는가 판단한다(S18). While performing the dehydration, the current RPM is measured to determine the RPM deviation between the target RPM and the current RPM (S16). At this time, it is determined whether a deviation of about 70 RPM occurs (S18).

이렇게 RPM 편차를 판단하여 RPM 편차가 발생하지 않을 경우에는 본탈수 운전 방법에 따라 탈수운전이 완료될 때까지 최고 RPM 까지 상승하여 탈수운전을 수행하여 탈수운전이 완료될 경우 탈수운전을 중지시키게 된다(S28)(S26). If the RPM deviation does not occur by judging the RPM deviation, the dehydration operation is stopped when the dehydration operation is completed by rising to the maximum RPM until the dehydration operation is completed according to the main dehydration operation method. S28) (S26).

그러나, RPM 편차가 70RPM 이상 차이가 발생할 경우에는 세탁수위를 측정하게 된다(S20). However, when the RPM deviation is more than 70RPM difference is measured the washing level (S20).

이때 측정한 세탁수위가 일정수위 이상 발생할 경우에는 급수호스의 불량으로 판단하여 급수호스 불량의 에러 메시지를 표시하고 모터를 정지시켜 탈수운전을 중지시키게 된다(S24)(S26). At this time, if the measured washing water level is above a certain level, it is determined that the water supply hose is defective and displays an error message of a water supply hose failure, and stops the motor to stop the dehydration operation (S24) (S26).

반면 측정한 세탁수위가 일정수위 이상 발생하지 않았을 경우에는 밸런스 이상에 의해 RPM 편차가 발생한 것으로 판단하여 밸런스 탈수를 다시 수행하게 된다(S10). On the other hand, if the measured washing level does not occur above a certain level, it is determined that the RPM deviation is caused by the balance abnormality, and the balance is dehydrated again (S10).

이와 같이 본탈수시 세탁수위를 측정하여 급수호스의 불량등에 의해 급수가 이루어지고 있는 경우를 판단하여 탈수운전의 이상원인을 정확하게 경고할 수 있게 된다. In this way, by measuring the washing water level during the main dehydration, it is possible to accurately warn the cause of the abnormal operation of the dehydration operation by determining the case where the water supply is made due to the failure of the water supply hose.

상기한 바와 같이 본 발명은 드럼 세탁기의 탈수운전 중 본탈수시 세탁조의 수위를 측정하여 급수호스의 불량으로 인한 이상급수로 인해 탈수이상이 발생할 경우 정확한 원인을 표시하고 탈수운전을 중지시켜 안정된 탈수운전을 수행할 수 있는 이점이 있다. As described above, the present invention measures the water level of the washing tank during the dehydration operation of the drum washing machine to display the exact cause when the dehydration abnormality occurs due to the abnormal water supply due to the failure of the water supply hose, and stops the dehydration operation to stabilize the dehydration operation. There is an advantage to this.
