본 발명은 드럼세탁기에 관한 것으로 특히, 모터를 오프시킨 후에 수위가 잔 잔해질 때까지 기다렸다가 수위를 감지하므로써 수위감지의 안정성을 향상시키는 드럼세탁기의 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum washing machine, and more particularly, to a control method of a drum washing machine which improves stability of water level detection by waiting for the water level to remain calm after turning off the motor.

일반적으로 드럼세탁기는 세제와 세탁수 및 세탁물이 드럼내에 투입된 상태에서 모터의 구동력을 전달받아 회전하는 드럼과 세탁물의 마찰력을 이용하여 세탁을 행하는 방식으로서, 세탁물의 손상이 거의 없고, 세탁물이 서로 엉키지 않으며, 두드리고 비벼빠는 세탁효과를 낼 수 있다.In general, the drum washing machine is a method of washing by using the rotating drum and the friction of the laundry by receiving the driving force of the motor in the state in which detergent, washing water and laundry are put into the drum, there is almost no damage to the laundry, the laundry is not tangled with each other Tapping and rubbing can have a washing effect.

이하, 첨부된 도면을 참조하여 종래 기술을 설명하면 다음과 같다.Hereinafter, the prior art will be described with reference to the accompanying drawings.

도 1은 일반적인 드럼 세탁기의 구조도이다.1 is a structural diagram of a general drum washing machine.

도면에 도시된 바와 같이, 드럼세탁기는 하우징(50)과, 상기 하우징(50) 내부에 댐퍼(51) 및 스프링(52)으로 지지되는 터브(53)와, 상기 터브(53) 내면에 회전 가능하게 설치된 드럼(54)과, 상기 드럼(54)에 연결됨과 아울러 모터(55)에 벨트(56)로 연결된 풀리(57)로 구성되어 있다.As shown in the drawing, the drum washing machine is rotatable to the housing 50, the tub 53 supported by the damper 51 and the spring 52 inside the housing 50, and the inner surface of the tub 53 And a pulley 57 connected to the drum 54 and connected to the motor 55 by a belt 56.

또한, 상기 터브(53) 및 드럼(54)에 세탁수를 공급하기 위해 설치된 급수배관(58) 및 급수밸브(59)와, 상기 세탁수가 세탁시 순환되도록 순환펌프(60)를 개재하여 설치된 순환배관(61)과, 상기 순환배관(61)에서 물을 배수시키기 위해 설치된 배수펌프(62)로 구성되어 있다.In addition, the tub 53 and the drum 54 is provided with a water supply pipe 58 and a water supply valve 59 installed to supply the wash water, and the circulation is installed through the circulation pump 60 so that the wash water is circulated during washing It consists of a piping 61 and the drain pump 62 provided in order to drain water from the said circulation pipe 61. As shown in FIG.

특히, 상기 터브(53) 내부에는 세탁수를 가열하기 위하여 히터(63)가 설치되어 있고, 드럼(54)을 간헐 개폐시키도록 도어(64)가 설치되어 있으며, 드럼(54)에는 세탁수의 드럼(54) 내부 순환을 위해 리프터(65)가 설치되어 있다.In particular, the tub 53 is provided with a heater 63 to heat the wash water, a door 64 is installed to intermittently open and close the drum 54, the drum 54 of the wash water A lifter 65 is provided for circulation of the drum 54.

상기한 드럼세탁기의 동작을 살펴보면 다음과 같다. Looking at the operation of the drum washing machine as follows.                         

도 2는 종래 기술에 따른 드럼세탁기의 동작을 나타낸 순서도이다. 2 is a flow chart showing the operation of the drum washing machine according to the prior art.

사용자가 세탁을 하기 위하여 도어(64)를 열고 세탁물을 드럼(54) 내부에 투입하고 도어(64)를 닫은 후에 드럼세탁기를 동작시키면 외부로부터 세탁수가 공급되게 된다.When the user opens the door 64 for washing, puts laundry into the drum 54, closes the door 64, and operates the drum washing machine, washing water is supplied from the outside.

급수가 완료되면(S201), 모터(55)와 순환펌프(60)가 구동되어 드럼(54)내의 세탁물에 세탁수가 고르게 적셔지게 된다(S202).When the water supply is completed (S201), the motor 55 and the circulation pump 60 is driven to wash the washing water evenly in the laundry in the drum 54 (S202).

즉, 상기 모터(55) 구동에 의해 드럼(54)이 회전되고, 상기 터브(53)의 저면으로 흐르는 세탁수는 순환배관(61)을 통해 순환펌프(60)로 유입되고 순환펌프(60)에 의해 다시 터브(53) 상면으로 강제 순환되어 드럼(54) 내에 뿌려지면서 세탁물에 세탁수가 고르게 적셔지게 된다. That is, the drum 54 is rotated by the driving of the motor 55, and the wash water flowing to the bottom surface of the tub 53 flows into the circulation pump 60 through the circulation pipe 61 and the circulation pump 60. By the forced forced circulation back to the top surface of the tub 53 is sprinkled in the drum 54, the washing water is evenly soaked in the laundry.

이어, 모터(55)가 온(ON) 상태인지를 확인한다(S203).Next, it is checked whether the motor 55 is in an ON state (S203).

포적심 행정 동안에 모터(55)는 계속해서 구동하지 않고 온/오프(on/off)를 4차례 정도 반복한다.The motor 55 repeats on / off four times without continuing to drive during the packing stroke.

이때, 상기 순환펌프(60)는 모터(55)의 온(ON)/오프(OFF)에 관계없이 계속해서 구동한다. At this time, the circulation pump 60 is continuously driven regardless of the ON (ON) / OFF (OFF) of the motor 55.

상기 스텝 203의 확인 결과, 모터(55)가 온(ON) 상태이면 상기 스텝 202(S202)로 리턴하여 모터(55)와 순환펌프(60)를 계속 구동시킨다.As a result of checking in step 203, if the motor 55 is in an ON state, the motor 55 returns to step 202 (S202) to continue driving the motor 55 and the circulation pump 60.

반면, 모터(55)가 오프(OFF) 상태이면 수위감지센서(도시하지 않음)를 이용하여 수위를 감지한다(S204).On the other hand, when the motor 55 is in an OFF state, the water level is sensed using a water level sensor (not shown) (S204).

이어, 상기 스텝 202(S202) 에서 스텝 204(S204)의 과정을 4차례 정도 반복 실시한 후에 포적심 행정을 완료한다.Subsequently, the process of step 204 (S204) is repeated about four times in step 202 (S202), and then the braking stroke is completed.

포적심 행정이 완료되면, 히터(63)에 전원이 인가되어 세탁수가 가열되고 본격적인 세탁이 이루어지게 된다.When the foaming stroke is completed, power is applied to the heater 63 so that the washing water is heated and washing is performed in earnest.

이상에서 설명한 바와 같이, 종래 기술에서는 모터가 오프(OFF)되면 세탁수의 수위를 감지하고 있다. As described above, in the prior art, the water level of the washing water is detected when the motor is turned off.

그런데, 모터가 오프되더라도 모터 구동시에 생긴 수류로 인해 한동안 세탁수가 잔잔하지 않기 때문에 수위감지가 불안정하다.However, even when the motor is off, the water level detection is unstable because the washing water does not remain for a while due to the water flow generated when the motor is driven.

또한, 모터가 오프(OFF)되어 있는 동안에도 순환펌프(60)는 구동되기 때문에 세탁수가 계속 순환하므로 순환펌프(60) 및 순환배관(61)에 들어있는 물의 양만큼 수위는 낮아지게 된다.In addition, since the circulation pump 60 is driven even while the motor is OFF (OFF), since the washing water continues to circulate, the water level is lowered by the amount of water contained in the circulation pump 60 and the circulation pipe 61.

뿐만 아니라, 순환되는 물이 드럼(54) 내로 뿌려지게 되는데, 이 물에 의해 세탁수가 불안정하게 요동치게 되므로 수위감지가 불안정해 진다.In addition, the circulated water is sprinkled into the drum 54, and the washing water is unstable by this water, so that the water level detection becomes unstable.

본 발명은 상기한 바와 같은 문제점들을 해결하기 위하여 안출한 것으로 수위 감지의 안정성을 향상시키기 위한 드럼세탁기의 제어방법을 제공하는데 그 목적이 있다.An object of the present invention is to provide a control method of a drum washing machine for improving the stability of the water level detection to solve the problems as described above.

본 발명에 따른 드럼세탁기의 제어방법은 급수가 완료되면 모터와 순환펌프를 구동시키는 제 1 단계와, 모터가 온 상태인지를 확인하는 제 2 단계와, 상기 제 2 단계의 확인 결과 모터가 온 상태이면 상기 제 1 단계로 리턴하고, 모터가 오프 상태이면 순환 펌프를 오프시키는 제 3 단계와, 모터가 오프된 상태이면 모터 오프 구간 종료 시점까지 대기하는 제 4 단계 그리고, 모터 오프 구간 종료 시점이 되면 수위를 감지하는 제 5 단계로 이루어짐을 특징으로 한다.The control method of the drum washing machine according to the present invention includes a first step of driving the motor and the circulation pump when water supply is completed, a second step of checking whether the motor is on, and a result of the checking of the second step, the motor is turned on If the motor is in the off state, the third step of turning off the circulation pump, if the motor is off, the fourth step of waiting until the end of the motor off period, and the end of the motor off period And a fifth step of detecting the water level.

바람직하게, 상기 제 5 단계는 세탁수가 설정수위에 도달하였는지를 판단하는 제 6 단계와, 상기 제 6 단계의 판단 결과, 설정수위에 도달하지 못한 경우에는 재급수한 후에 상기 제 6 단계로 리턴하고 설정수위에 도달한 경우에는 모터와 순환펌프를 재구동시키는 제 7 단계로 이루지는 것을 특징으로 한다.Preferably, the fifth step is a sixth step of determining whether the wash water has reached the set water level, and if the set water level does not reach the set water level as a result of the determination of the sixth step, returns to the sixth step after re-watering and setting When the water level is reached, the motor and the circulating pump are driven in a seventh step.

본 발명의 다른 목적, 특징 및 이점들은 첨부한 도면을 참조한 실시예들의 상세한 설명을 통해 명백해 질 것이다.Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 3은 본 발명에 따른 드럼세탁기의 제어 방법을 나타낸 순서도이다.3 is a flowchart illustrating a method of controlling a drum washing machine according to the present invention.

사용자가 세탁을 하기 위하여 도어(64)를 열고 세탁물을 드럼(54) 내부에 투입하고 도어(64)를 닫은 다음에 드럼세탁기를 동작시키면 외부로부터 세탁수가 공급되게 된다.When the user opens the door 64 for washing, puts laundry into the drum 54, closes the door 64, and then operates the drum washing machine, washing water is supplied from the outside.

급수가 완료되면(S301), 모터(55)와 순환펌프(60)가 구동되어 드럼(54)내의 세탁물이 고르게 적셔지게 된다(S302).When the water supply is completed (S301), the motor 55 and the circulation pump 60 is driven to uniformly wet the laundry in the drum 54 (S302).

즉, 상기 모터(55) 구동에 의해 드럼(54)이 회전되고, 상기 터브(53)의 저면으로 흐르는 세탁수는 순환배관(61)을 통해 순환 펌프(60)로 유입되고 순환 펌프(60)에 의해 다시 터브(53) 상면으로 강제 순환되어 드럼(54) 내에 뿌려지면서 세탁물이 고르게 적셔지게 된다.That is, the drum 54 is rotated by the driving of the motor 55, and the wash water flowing to the bottom surface of the tub 53 flows into the circulation pump 60 through the circulation pipe 61 and the circulation pump 60. By the forced force circulated back to the tub 53 by the top sprayed in the drum 54, the laundry is evenly wet.

이어, 모터(55)가 온(ON) 상태인지를 확인한다(S303).Subsequently, it is checked whether the motor 55 is in an ON state (S303).

포적심 행정 동안에 모터(55)를 계속해서 구동하지 않고 온/오프(on/off)를 4차례 정도 반복한다.The on / off is repeated about four times without continuously driving the motor 55 during the packing stroke.

상기 스텝 303의 확인 결과, 모터(55)가 온(ON) 상태이면 상기 스텝 302(S302)로 리턴하여 모터(55)와 순환펌프(60)를 계속 구동시킨다.As a result of checking in step 303, if the motor 55 is in an ON state, the motor 55 returns to step 302 (S302) to continue driving the motor 55 and the circulation pump 60.

반면, 모터(55)가 오프(OFF) 상태이면 순환펌프(60)를 오프(OFF)시킨다(S304).On the other hand, when the motor 55 is in an OFF state, the circulation pump 60 is turned off (S304).

상기 모터(55)와 순환펌프(60)가 오프됨에 따라서 세탁수가 강제 순환되지는 않지만 그간의 모터(55) 및 순환펌프(60) 구동에 따른 수류에 의해 드럼(54) 내의 세탁수는 잔잔하지 않고 요동칠 것이다.The washing water is not forcedly circulated as the motor 55 and the circulation pump 60 are turned off, but the washing water in the drum 54 is not calm due to the water flow caused by the motor 55 and the circulation pump 60. Will not shake.

따라서, 이 시점에서의 수위를 감지하기가 어렵고 감지하더라도 정확도가 떨어질 것이다.Therefore, it is difficult to detect the water level at this point and the accuracy will be reduced even if it is detected.

이에, 본 발명에서는 모터(55)를 오프시키고 나서 바로 수위를 감지하지 않고 모터(55)를 오프(OFF)시킨 다음에 모터(55) 오프(OFF) 구간 종료 시점까지 대기하여 수위가 안정될 때까지 기다렸다가 수위를 감지하고자 한다.Therefore, in the present invention, when the water level is stabilized by waiting until the end of the motor 55 OFF section after turning off the motor 55 without sensing the water level immediately after turning off the motor 55. Wait until you want to detect the water level.

즉, 상기 순환펌프(60)를 오프시킨 후에 모터(55) 오프(OFF) 구간 종료 시점에 도달하였는지를 지속적으로 확인한다(S305).That is, after turning off the circulation pump 60, it is continuously checked whether the end point of the motor 55 OFF section is reached (S305).

상기 확인 결과, 모터(55) 오프 구간 종료 시점에 도달하지 않았으면 모터(55)와 순환펌프(60)를 모두 오프(OFF)시킨 상태로 대기한다. As a result of the check, if the end of the motor 55 off section is not reached, the motor 55 and the circulation pump 60 are both turned off.                     

이 대기 시간동안에는 모터(55)와 순환펌프(60)에 의한 강제 순환이 없으므로 세탁수는 차츰 잔잔해 질 것이다.During this waiting time, there is no forced circulation by the motor 55 and the circulation pump 60, so the washing water will gradually be calm.

이후, 모터(55) 오프 구간 종료 시점에 도달하면 수위감지센서(도시하지 않음)를 이용하여 수위를 감지한다.Thereafter, when the end of the motor 55 off section is reached, the water level is sensed using a water level sensor (not shown).

즉, 세탁수가 설정수위에 도달하였는지 여부를 판단하여(S306), 설정수위에 도달하지 않았으면 재급수를 실시한 다음에(S307), 상기 스텝 306(S306)으로 리턴하여 세탁수가 설정수위에 도달하였는지 여부를 다시 판단한다.That is, it is determined whether the washing water has reached the set water level (S306). If the washing water level has not been reached (S306), the water is supplied again (S307), and then returned to step 306 (S306) to see if the washing water has reached the water level. Determine again.

판단 결과, 세탁수가 설정수위에 도달되었으면 수위 감지를 마치고, 모터(55)와 순환펌프(60)를 재구동시킨다(S308).As a result of the determination, when the wash water reaches the set water level, the water level is sensed, and the motor 55 and the circulation pump 60 are driven again (S308).

그리고, 포적심이 충분히 이루어질 수 있도록 상기 스텝 302(S302)에서 스텝 307(S307)의 과정을 4차례 정도 반복한다.Then, in step 302 (S302), the process of step 307 (S307) is repeated about four times so that the foaming can be sufficiently performed.

이후, 포적심 행정이 완료되면 히터(63)에 전원이 인가되어 세탁수가 가열되고 본격적인 세탁이 이루어지게 된다.Subsequently, when the foaming stroke is completed, power is applied to the heater 63 so that the washing water is heated and full washing is performed.

상기와 같은 본 발명의 드럼세탁기의 제어방법은 다음과 같은 효과가 있다.The control method of the drum washing machine of the present invention as described above has the following effects.

첫째, 모터가 오프된 후에 수위가 잔잔해질 때까지 대기하였다가 수위를 감지하므로 안정된 수위감지가 가능하다.First, since the motor waits until the water level becomes calm after the motor is turned off, the water level is sensed so that stable water level detection is possible.

둘째, 모터뿐 아니라 순환펌프도 정지된 상태에서 수위를 감지하기 때문에 안정된 수위감지가 가능하다.Secondly, not only the motor but also the circulation pump detects the water level in the stopped state, which enables stable water level detection.

셋째, 순환펌프를 정지시킨 다음에 수위를 감지하기 때문에 세탁수가 세탁수 순환으로 인해 수위가 낮아지는 현상을 방지할 수 있다.Third, since the water level is sensed after stopping the circulation pump, washing water can be prevented from being lowered due to the water circulation.

이상 설명한 내용을 통해 당업자라면 본 발명의 기술 사상을 이탈하지 아니하는 범위에서 다양한 변경 및 수정이 가능함을 알 수 있을 것이다.Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.
