도 1은 본 발명의 실시예에 따른 세탁기의 제어방법이 도시된 순서도.1 is a flow chart illustrating a control method of a washing machine according to an embodiment of the present invention.

본 발명은 세탁물 처리기기의 제어방법에 관한 것으로서, 특히 배수도중 일시정지되었다가 재구동시 다른 행정에 앞서 배수가 이루어지도록 함으로써, 사이폰 현상을 방지할 수 있는 세탁물 처리기기의 제어방법에 관한 것이다.The present invention relates to a method for controlling a laundry treatment device, and more particularly, to a method for controlling a laundry treatment device which can prevent a siphon phenomenon by allowing water to be drained prior to another stroke during a stop and restart during drainage.

일반적으로 세탁물 처리기기는 물과 세제 및 기계적인 작용 등을 이용하여 의복, 침구 등의 세탁물에 묻은 오염을 떼어 내는 세탁기와, 히터에 의해 가열된 건조한 열풍과 기계적인 작용 등을 이용하여 젖은 포를 건조하는 건조기와, 세탁 기능과 건조 기능을 겸하는 건조겸용 세탁기로 구분된다. In general, a laundry treatment machine uses a washing machine to remove dirt from laundry such as clothes and bedding by using water, detergent, and mechanical action, and dry hot air heated by a heater and mechanical action. It is divided into a dryer to dry, and a dry washing machine which has a washing function and a drying function.

종래 기술에 따른 세탁기는 외관을 형성하는 캐비닛과, 상기 캐비닛의 내측에 설치된 터브와, 상기 터브의 내측에 설치되고 세탁물이 수용되는 드럼과, 상기 드럼을 회전시키는 모터와, 상기 터브내로 세탁수를 급수하는 급수장치와, 상기 터브내의 세탁수를 배수하는 배수장치를 포함한다. The washing machine according to the related art includes a cabinet forming an exterior, a tub installed inside the cabinet, a drum installed inside the tub and receiving laundry, a motor for rotating the drum, and washing water into the tub. A water supply device for supplying water and a drainage device for draining the wash water in the tub.

상기 급수장치는 외부에서 급수되는 물을 단속하는 급수밸브를 포함하고, 상기 배수장치는 상기 터브내의 물을 외부로 펌핑하는 배수펌프를 포함한다. The water supply device includes a water supply valve for regulating water supplied from the outside, and the drainage device includes a drain pump for pumping water in the tub to the outside.

상기와 같이 구성된 세탁기는 상기 드럼 내부에 세탁물을 투입한 후, 상기 급수장치를 통해 세제와 세탁수가 급수되면, 상기 모터가 구동되고 상기 드럼이 회전되면서 세탁행정이 이루어진다. In the washing machine configured as described above, after the laundry is put into the drum, the detergent and the washing water are supplied through the water supply device, the motor is driven, and the drum rotates to perform the washing operation.

상기와 같은 세탁행정이 종료되면 상기 모터는 정지하고, 상기 터브내의 오염된 물을 상기 배수장치를 통해 외부로 배수하는 배수행정이 이루어진다. 이 때, 상기 배수펌프가 상기 터브내의 물을 펌핑하여 배수시킨다. When the washing stroke is completed, the motor stops, and a drainage stroke is performed to drain the contaminated water in the tub to the outside through the drainage device. At this time, the drain pump pumps the water in the tub to drain.

그러나, 종래 기술에 따른 세탁기는 배수가 진행되는 도중에 사용자에 의해 배수가 일시 정지되거나, 전원이 오프되어 세탁기의 동작이 정지될 경우, 상기 배수펌프가 작동하지 않음에도 불구하고 사이폰 현상에 의해 상기 터브내의 물이 서서히 빠져나가는 경우가 발생되고, 이로 인해 세탁기가 재구동되어 급수를 실시하더라도 계속해서 배수가 이루어져 물이 낭비되고 세탁시간이 길어지는 문제점이 있다. However, in the washing machine according to the related art, when the drainage is temporarily stopped by the user while the drainage is in progress, or when the washing machine is stopped due to the power off, the washing machine does not operate due to the siphon phenomenon. When the water in the tub is gradually drained, this causes a problem in that even if the washing machine is restarted and supplied with water, the water is continuously drained and the washing time is long.

본 발명은 세탁물 처리기기의 구동시 사이폰 현상이 방지될 수 있는 세탁물 처리기기의 제어방법을 제공하는데 그 목적이 있다.An object of the present invention is to provide a control method of a laundry treatment device that can prevent the siphon phenomenon when the laundry treatment device is driven.

상기한 과제를 해결하기 위한 본 발명은 세탁물 처리기기의 구동이 시작되면, 배수펌프를 온시키는 온시키는 배수펌프 온 단계와, 상기 배수펌프가 온되는 동안 터브내의 수위를 감지하고, 감지된 수위가 기설정된 수위 이하인지 판단하는 수위 판단단계와, 상기 수위 판단단계에서 감지된 수위가 기설정된 수위 이하라고 판단되면, 판단시점으로부터 소정의 시간을 경과한 후 상기 배수펌프를 오프시키는 배수펌프 오프단계를 포함하고, 상기 배수펌프 오프 단계 이후에는 입력된 행정을 시작하는 세탁물 처리기기의 제어방법을 제공한다. According to the present invention for solving the above problems, the operation of the laundry treatment device is started, the drain pump on step of turning on the drain pump, the water level in the tub while the drain pump is turned on, the detected water level is A water level determination step of determining whether the water level is lower than a predetermined level, and if the water level detected in the water level determination step is equal to or lower than a predetermined water level, a drain pump off step of turning off the drainage pump after a predetermined time elapses from the determination point It includes, and provides a control method of the laundry treatment machine to start the input stroke after the drain pump off step.

상기 배수펌프 온 단계는 세탁물 처리기기가 배수행정 중에 일시정지되었다가 재구동이 시작되었을 때 수행되는 것을 포함한다.The drain pump on step may be performed when the laundry treatment device is paused during the drain stroke and restarted.

상기 기설정된 수위는 상기 터브내에 물이 없는 공수위를 포함한다.The predetermined water level includes an air level without water in the tub.

이하, 본 발명의 실시 예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 세탁기의 제어방법이 도시된 순서도이다. 1 is a flowchart illustrating a control method of a washing machine according to an embodiment of the present invention.

먼저, 세탁기에 전원이 인가되고 사용자에 의해 세탁, 헹굼, 탈수, 건조 행정 중 어느 한 행정이 입력되면(S1), 제어부는 행정이 입력되기 이전에 상기 세탁기가 배수행정을 진행하다가 일시정지된 적이 있는지를 판단한다.(S2)First, when power is supplied to the washing machine and any one of washing, rinsing, dehydrating, and drying strokes is input by the user (S1), the control unit pauses while the washing machine proceeds to a drainage stroke before the stroke is input. (S2)

즉, 상기 세탁기가 터브내의 세탁수를 배수하는 도중에 사용자가 일시정지 버튼을 눌러 상기 세탁기의 구동을 정지시켰거나, 정전이나 기타 사용자의 부주의에 의해 전원이 오프되어 상기 세탁기의 구동이 정지되어, 상기 세탁기가 재구동되는 것인지를 판단한다. That is, while the washing machine drains the wash water in the tub, the user presses the pause button to stop the driving of the washing machine, or the power is turned off due to power failure or other user's carelessness to stop the driving of the washing machine. Determine whether the washing machine is restarted.

상기 세탁기가 재구동되었다고 판단되면, 사용자가 입력한 행정을 수행하기 이전에 배수펌프를 온시키는 배수펌프 온 단계를 수행한다.(S3) If it is determined that the washing machine is restarted, a drain pump on step of turning on the drain pump before performing the stroke input by the user is performed.

상기 배수펌프가 온되면, 배수중 일시정지로 인해 상기 터브내에 남아있는 세탁수가 펌핑되어 배수된다. When the drain pump is turned on, the wash water remaining in the tub is pumped and drained due to a pause during drainage.

그리고, 배수가 진행되는 동안에, 상기 터브내의 수위 변화를 감지하는 바, 즉, 상기 터브내의 수위를 감지하여(S4) 감지된 수위가 기설정된 수위 이하인지를 판단하는 수위 판단단계를 수행한다.(S5) 여기서, 상기 기설정된 수위는 상기 터브내의 세탁수가 모두 배수되어 상기 터브내에 세탁수가 없는 공수위이다. 따라서, 상기 감지된 수위가 공수위에 도달하면, 상기 터브내의 세탁수는 모두 배수되었다고 판단한다. In addition, while the drainage is in progress, the water level change in the tub is detected, that is, the water level in the tub is detected (S4) and the water level determination step of determining whether the detected water level is below the predetermined level is performed. S5) Here, the predetermined water level is an air supply level in which the wash water in the tub is drained so that the wash water is not in the tub. Therefore, when the detected water level reaches the airborne level, it is determined that the wash water in the tub has been drained.

이 때, 상기 감지된 수위가 공수위에 도달한 시점으로부터 소정의 시간을 경과할 때까지 배수가 계속해서 진행되도록 한다.(S6) 상기 소정의 시간은 상기 배수펌프와 배수벨로우즈 등에 남아있는 세탁수를 완전히 배수하기 위해 필요한 시간으로, 본 실시예에서는 20초로 설정한다. At this time, the drainage continues to proceed until a predetermined time elapses from the time when the detected water level reaches the airborne level. (S6) The predetermined time is for washing the water remaining in the drain pump and the drain bellows. The time required for complete drainage is set to 20 seconds in this embodiment.

소정의 시간이 경과하여 세탁수가 완전히 배수되고 나면, 상기 배수펌프를 오프시키는 배수펌프 오프단계가 수행된다.(S7) After the predetermined time has elapsed and the wash water is completely drained, a drain pump off step of turning off the drain pump is performed.

상기 배수펌프가 오프되면, 사용자가 입력한 행정을 수행한다.(S8) When the drain pump is turned off, the stroke input by the user is performed. (S8)

따라서, 사용자가 입력한 행정을 수행하는 동안에 사이폰 현상에 의해 세탁수가 배수되는 것이 사전에 방지될 수 있다. Therefore, the drainage of the wash water by the siphon phenomenon while performing the stroke input by the user can be prevented in advance.

또한, 세탁기가 배수 도중에 일시정지된 후 재구동된 경우에, 입력된 행정에 앞서 배수펌프를 온 시키기 때문에, 세탁기의 작동시간이 과도하게 길어지는 것이 방지된다. In addition, when the washing machine is paused in the middle of drainage and then restarted, the drainage pump is turned on prior to the input stroke, so that an excessively long operation time of the washing machine is prevented.

상기와 같이 구성되는 본 발명에 따른 세탁물 처리기기의 제어방법은 세탁물 처리기기의 구동시 사용자가 입력한 행정을 시작하기 이전에, 배수펌프를 온시켜 터브내의 세탁수를 배수시킴으로써, 행정 진행중에 사이폰 현상에 의해 배수되는 현상을 방지하여, 물과 에너지의 낭비를 방지함과 아울러 세탁시간이 증대되는 것을 방지할 수 있는 효과가 있다. According to the control method of the laundry treatment machine according to the present invention configured as described above, before starting the stroke input by the user during the operation of the laundry treatment machine, the drain pump is turned on to drain the wash water in the tub. By preventing the phenomenon of drainage by the phone phenomenon, it is possible to prevent the waste of water and energy, and to increase the washing time.
