도2는 본 발명 거품제거 플로우챠트Figure 2 is the present invention defoam flow chart

본 발명은 투과세탁기에 관한 것으로 특히, 세탁행정과 헹굼행정 사이, 그리고 헹굼행정 사이사이의 간헐탈수 행정시 거품을 감지하여 감지된 거품을 제거해 줌으로서 정상적인 간헐탈수를 하여 헹굼력을 향상시키고 모우터 및 기타 부품들의 손상을 방지하도록 하는 투과세탁기의 간헐탈수시 거품제거방법에 관한 것이다.The present invention relates to a permeable washing machine, and in particular, to detect the bubbles during intermittent dehydration stroke between the washing stroke and rinsing stroke, and between the rinsing stroke to remove the detected bubbles to improve the rinsing power by the normal intermittent dewatering and the motor and The present invention relates to a method for removing bubbles during intermittent dehydration of a permeable washing machine to prevent damage to other components.

일반적으로 투과세탁기는 교반과 통회전을 반복하며 세탁 및 헹굼공정을 진행하는 것은 주지와 같다.In general, the permeable washing machine repeats the stirring and passing through the rotating and proceeds the washing and rinsing process as is well known.

상기 세탁행정을 진행하여 완료된 후에는 헹굼공정을 진행하게 되며, 이때 상기 세탁행정과 헹굼행정 사이에는 간헐탈수 행정을 진행하여 헹굼력을 향상시키게 되지만, 세탁행정시 교반과 통회전중 통회전시에는 교반보다 더 많은 거품이 발 생하게 되어 간헐탈수시 다량의 거품으로 인하여 모우터에 부하가 걸리며 기타 부품들이 손상되는 문제점이 발생하게 된다.After the washing stroke is completed, the rinsing process is performed, and at this time, the rinsing power is improved by performing an intermittent dehydration stroke between the washing stroke and the rinsing stroke, but the stirring during the washing stroke and the general rotation during the general rotation than the stirring More bubbles are generated, which causes the load on the motor due to the large amount of bubbles during intermittent dehydration and damages to other parts.

즉, 상기 교반으로 인하여 발생된 거품과 통회전으로 인하여 발생된 거품은 세탁행정이 완료된 후 배수행정을 진행하게 되어도 세탁수와 함께 배출되지 않고 세탁물의 표면과 세탁외조에 남아있게 되며, 배수행정이 완료된 후 간헐탈수를 하게되면 세탁내조가 회전하며 세탁물에 남아있는 오수를 배출시키게 되지만, 상기 세탁내조와 세탁외조 사이에 있는 거품들이 마찰력을 발생시키며 정상적인 탈수시의 회전수를 발생시키지 못하게 한다.In other words, the foam generated due to the stirring and the bubble generated due to the barrel rotation is not discharged together with the wash water even after the washing stroke is completed, and remains on the surface of the laundry and the outer tub of the washing, When the intermittent dehydration is completed after the completion of the washing tub is rotated to discharge the sewage remaining in the laundry, but the foam between the washing tub and the washing tub to generate a friction force and prevent the rotation speed during normal dehydration.

또한, 상기 헹굼공정 사이사이에도 간헐탈수를 진행하게 되는바, 상기 간헐탈수시에도 남아있는 거품으로 인하여 정상적인 모우터의 회전수가 발생되지 않게 되어 모우터의 수명을 단축시켜 세탁기의 성능을 저하시키게 된다.In addition, the intermittent dehydration is performed between the rinsing steps, and since the bubbles remaining during the intermittent dehydration do not generate the normal rotation speed of the motor, thereby shortening the life of the motor and reducing the performance of the washing machine. .

따라서, 상기 간헐탈수시 세탁내조를 회전시키는 모우터에는 정상적인 회전수를 발생시키기 위해 과부하가 걸리게 되어 모우터에 손상이 발생됨과 동시에 세탁물에 남아있는 오수를 완전히 배출하지 못하게 됨으로서 헹굼력도 저하시키는 문제점을 초래하게 된다.Therefore, the motor that rotates the washing tank during the intermittent dehydration is overloaded to generate a normal number of revolutions, causing damage to the motor and at the same time not completely discharge the sewage remaining in the laundry, thereby reducing the rinsing power. Will result.

이와같은 문제점등을 해결 보완하기 위하여 본 발명은,In order to solve and solve such problems, the present invention,

간헐탈수시 세탁내조와 세탁외조 사이에 있는 거품을 감지하여 감지된 거품을 제거한 후 간헐탈수를 진행하도록 하는 투과세탁기의 간헐탈수시 거품제거방법 을 구현함에 그 목적이 있다.The purpose of the present invention is to realize a method of removing bubbles during intermittent dehydration of a permeable washing machine to detect intermittent dehydration and to detect intermittent dehydration and to detect intermittent dehydration.

상기와 같이 이루어진 구성에 따른 작용효과를 설명하면 먼저, 교반과 통회전을 반복하며 세탁행정을 마치면 간헐탈수가 시작되는 탈수가 시작되고, 상기 탈수가 진행된 후 2분이 경과하게 되면 RPM을 감지하는 단계에서 RPM이 400이상인지를 감지하여 400이상이면 거품이 간헐탈수에 영향을 주지 않으므로 정상적인 탈수 를 진행하게 되고, 상기 RPM이 400이하이면 거품에 의해 모우터에 과부하가 걸린것으로 판단하여 모우터의 RPM을 낮추며 거품제거운전을 하게 된다.Referring to the operation effect according to the configuration made as described above, first, repeating the stirring and passing through the washing cycle after the dehydration starts the intermittent dehydration starts, detecting the RPM when 2 minutes have passed after the dehydration proceeds Detect whether the RPM is 400 or more at 400 If the bubble does not affect the intermittent dehydration proceeds to normal dehydration, and if the RPM is less than 400, it is determined that the motor is overloaded by the foam RPM of the motor Lowers the defoaming operation.

그리고, 상기 거품제거운전을 시작하게 되면 먼저, 모우터를 정지시킨 후 냉수밸브를 개방하여 세탁외조 내부로 세탁수를 공급하게 되고 다시 모우터를 동작시켜 1분이 경과되었는지 감지하게 되며, 상기 감지에서 1분이 경과되면 모우터를 정지시키고 1분 30초가 경과됨을 감지하여 다시 간헐탈수행정을 진행하게 된다.When the bubble removing operation is started, first, the motor is stopped and then the cold water valve is opened to supply the washing water to the inside of the washing tank, and the motor is operated again to detect whether 1 minute has elapsed. When 1 minute has elapsed, the motor is stopped, and when 1 minute 30 seconds has elapsed, the intermittent dehydration process is performed again.

이때, 상기 간헐탈수 행정으로 모우터가 2분동안 회전하면 RPM을 감지하여 400이상인지를 판단하게 되는데, 상기 RPM이 400이상이면 거품이 제거된 것으로 판단하여 정상적인 탈수행정에 들어가지만, 400이하로 감지되면 다시 거품제거운전단계로 돌아가 거품을 제거하게 되며, 또한 상기 거품제거운전을 2회이상 반복하였을 경우에는 다량의 거품이 발생되어 제거되지 않음을 판단하여 간헐탈수행정을 삭제하고 헹굼행정으로 들어가게 된다.At this time, when the motor rotates for 2 minutes by the intermittent dehydration stroke, it detects RPM and determines whether it is 400 or more. If the RPM is 400 or more, it is determined that bubbles are removed and enters a normal dehydration stroke, but is less than 400. When it is detected, it returns to the bubble removing operation step again to remove bubbles, and if the bubble removing operation is repeated two or more times, it is determined that a large amount of bubbles are not removed and the intermittent dehydration stroke is deleted and the rinsing stroke is entered. .

그리고, 상기 간헐탈수는 헹굼행정 사이사이도 진행하게 되므로 간헐탈수행정시 2회이상 거품제거운전을 하여도 거품이 제거되지 않으면 다음의 단계로 넘어가게 된다.In addition, the intermittent dehydration proceeds between rinsing strokes, so if bubbles are not removed even if the bubble removing operation is performed two or more times during the intermittent dehydration stroke, the process proceeds to the next step.

따라서, 본 발명은 간헐탈수시 거품을 제거하며 간헐탈수를 하게 됨으로서, 종래 거품을 제거하지 않고 간헐탈수를 하여 모우터에 과부하가 걸림으로 인한 모우터의 손상 및 기타 부품들의 손상을 방지할 수 있게 되고, 또한 종래 거품으로 인해 정상적인 회전수로 탈수하지 못하여 세탁물에 오수가 남아 헹굼력이 저하되는 것 또한 방지함으로서, 고장이 없어 투과세탁기를 장기간 사용할 수 있게 되고, 헹 굼력의 향상으로 제품의 이미지를 향상시킬 수 있게 된다.Therefore, the present invention is to remove the bubbles during intermittent dehydration and intermittent dehydration, to prevent the damage of the motor and damage of other parts due to the overload of the motor by intermittent dehydration without removing the conventional foam Also, it prevents dehydration at normal rotational speed due to the conventional foam and prevents the rinsing power from being lowered, thereby preventing the malfunction of the washing machine. It can be improved.

본 발명 거품제거운전단계는 간헐탈수시 세탁내조와 세탁외조 사이의 거품을 제거하는 단계로서, 상기의 설명에서와 같이 특정한 범위 및 단계가 아닌 세탁기의 용량에 따라, 그리고 사용조건에 따라 그 범위 및 단계를 설정하여도 된다.The defoaming operation step of the present invention is a step of removing bubbles between the washing tank and the outer tub during intermittent dehydration, not according to the specific range and step as described above, but depending on the capacity of the washing machine and the use conditions. You may set a step.

이와같이 된 본 발명은 간헐탈수를 진행한 후 일정시간 경과후에 임의로 지정된 회전수에 도달됨을 감지하여 거품의 유무를 감지한 후 감지된 거품을 제거하고 다시 간헐탈수를 진행하도록 함으로서 세탁수에 남아있는 오수를 완전히 배출하여 헹굼력을 향상시키는 한편, 정상적인 모우터의 회전수를 발생시킬 수 있으므로 모우터에 과부하가 걸리는 것을 방지하여 모우터 및 기타 부품들의 손상을 방지할 수 있는 유용한 효과를 갖는다.In the present invention, the intermittent dehydration detects the presence of a predetermined number of revolutions after a certain period of time after the intermittent dehydration, detects the presence of bubbles, removes the detected bubbles, and proceeds to intermittent dehydration. It is possible to prevent the overload of the motor to prevent damage to the motor and other parts, so as to improve the rinsing power by completely exhausting the rinsing power, while generating a normal rotation speed of the motor.
