본 발명은 드럼 세탁기에 관한 것으로서, 더욱 상세하게는 탈수 행정시 급수밸브의 고장을 출력하여 드럼 세탁기 과부하 제어 장치 및 방법에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to a drum washing machine overload control apparatus and method by outputting a failure of the water supply valve during the dehydration stroke.

일반적으로, 저수형 세탁기는 펄세이터의 회전구동을 통하여 저수조 내의 세탁수에 잠겨진 세탁물을 교반하는 것으로 세탁운전을 실행하는 반면에, 드럼 세탁기는 세탁물이 투입된 드럼을 수평회전시키는 동작으로 세탁운전을 실행하게 된다. 따라서 드럼 세탁기는 일반 저수형 세탁기와는 다른 기계적인 구조를 가지게 된다.In general, the low water type washing machine executes the washing operation by stirring the laundry immersed in the washing water in the water tank by rotating the pulsator, while the drum washing machine executes the washing operation by rotating the drum in which the laundry is put horizontally. Done. Therefore, the drum washing machine has a mechanical structure different from that of a general water washing machine.

이와 같은 드럼세탁기의 동작과정을 보면, 먼저 사용자가 드럼 내에 세탁물을 투입하고 스타트 스위치를 온하면 마이컴은 드럼에 투입된 세탁물의 중량을 검출하여 해당 세탁물의 중량에 적정한 급수량을 결정하고 급수를 시작한다. Looking at the operation of the drum washing machine, when the user first puts laundry in 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 appropriate for the weight of the laundry, and starts water supply.

급수가 진행되어 드럼을 둘러싸고 있는 저수조에 설정된 수위까지 저수되면 모터의 구동에 따라 드럼이 회전하면서 세탁물의 낙차에 의한 세탁이 진행되게 된다. 이러한 세탁은 세탁물의 중량에 의해 설정되는 시간동안 진행한다.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 motor, and washing is performed by the drop of laundry. This washing proceeds for a time set by the weight of the laundry.

이후 세탁행정이 완료되면 저수조의 오염된 세탁수를 배수펌프에 의해 외부로 배출하는 배수동작과 동시에 탈수행정을 실행한 후, 설정된 횟수만큼 다시 급수하고, 세탁행정을 소정 횟수동안 반복한다. 또한, 세탁행정이 완료되면 후속해서 헹굼 행정과 탈수 행정을 수행한다.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 drainage pump. In addition, when the washing administration is completed, the rinsing stroke and the dehydration stroke are subsequently performed.

특히, 탈수 행정은 헹굼 행정 후, 세탁물에 스며있는 세탁수를 배출시키는 것으로서, 드럼이 고속으로 회전하게 되는데, 이 때 급수밸브가 고장나 드럼 내부에 세탁수가 급수되는 경우에는 구동모터에 과부하가 걸려 드럼 세탁기가 고장나는 문제점이 있었다.In particular, the dehydration stroke discharges the wash water permeating the laundry after the rinsing stroke, and the drum rotates at a high speed. At this time, when the water supply valve is broken or the washing water is supplied to the drum, the driving motor is overloaded. There was a problem that the drum washing machine is broken.

본 발명은 전술한 문제점을 개선하기 위해 창안된 것으로서, 탈수 행정 개시 후 설정 시간이 경과하면 드럼의 회전을 정지시키고 수위를 체크하여 수위가 설정 수위 이상이면 급수밸브의 고장을 출력하는 드럼 세탁기 과부하 제어 장치 및 방법을 제공하는 데 그 목적이 있다.The present invention has been made to improve the above-mentioned problems, the drum washing machine overload control to stop the rotation of the drum after the set time after the start of the dehydration stroke and check the water level to output a failure of the water supply valve when the water level is above the set water level It is an object of the present invention to provide an apparatus and method.

이하에서는 본 발명의 실시예를 첨부된 도면을 참조하여 상세하게 설명한다. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 은 본 발명의 실시예에 따른 드럼 세탁기 탈수 행정 제어 장치의 블럭 구성도이다. 1 is a block diagram of a drum washing machine dehydration stroke control apparatus according to an embodiment of the present invention.

본 발명의 실시예에 따른 드럼 세탁기 탈수 행정 제어 장치는 드럼(미도시) 내부의 수위를 검출하는 수위센서(20), 드럼 내부에 세탁수를 급수하는 급수 밸브(30), 드럼을 회전시키는 구동모터(40), 급수밸브의 에러를 출력하는 에러 출력부(50)를 구비한다. Drum washing machine dehydration stroke control apparatus according to an embodiment of the present invention is a water level sensor 20 for detecting the water level inside the drum (not shown), a water supply valve 30 for supplying the wash water in the drum, the drive to rotate the drum An error output unit 50 for outputting an error of the motor 40 and the water supply valve is provided.

특히, 에러 출력부(50)는 부저를 통해 경고음을 출력하거나 드럼 세탁기의 키패널에 설치된 디스플레이 패널을 통해서 경고하는 것을 모두 포함한다.In particular, the error output unit 50 includes a warning sound through the buzzer or includes a warning through the display panel installed on the key panel of the drum washing machine.

마지막으로, 마이컴(10)은 상기한 드럼 세탁기 탈수 행정 제어 장치를 전반적으로 제어하는 것으로서, 탈수 행정 개시 후, 설정 시간이 경과하면 구동모터(40)를 제어하여 드럼의 회전을 정지시키고, 수위센서(20)를 통해 드럼 내부의 수위를 검출하도록 하여 이 때 수위가 기 설정된 설정 수위 이상이면 에러 출력부(50)로 급수 밸브 고장 및 과부하 발생 위험성을 경고한다.Finally, the microcomputer 10 generally controls the above-described drum washing machine dehydration stroke control device. After the start of the dehydration stroke, the microcomputer 10 controls the driving motor 40 to stop the rotation of the drum and the water level sensor. The water level inside the drum is detected through 20, and if the water level is higher than the preset level, the error output unit 50 warns of a risk of water supply valve failure and overload occurrence.

이러한 마이컴(10)의 제어과정은 도 2 를 통해서 상세하게 설명한다. The control process of the microcomputer 10 will be described in detail with reference to FIG. 2.

도 2 는 본 발명의 실시예에 따른 드럼 세탁기 탈수 행정 제어 방법의 순서도이다. 2 is a flowchart of a drum washing machine dewatering stroke control method according to an embodiment of the present invention.

본 발명의 실시예에 따른 드럼 세탁기 탈수 행정 제어 방법은 최초, 탈수 행정이 개시(S10)되면 시간을 카운트하고 구동모터(40)를 제어하여 드럼을 회전시킨다.In the drum washing machine dehydration stroke control method according to an embodiment of the present invention, when the dehydration stroke is started (S10), the drum is counted by controlling the time and controlling the driving motor 40.

이 후, 설정시간이 경과하는 지를 판단(S20)하여 설정시간을 경과하면, 구동모터(40)를 제어하여 드럼의 회전을 정지(S30)시킨다. After that, it is determined whether the set time has elapsed (S20), and when the set time has elapsed, the driving motor 40 is controlled to stop the rotation of the drum (S30).

드럼의 회전이 정지되면, 수위센서(20)를 제어하여 드럼 내부의 수위를 검출(S40)하고, 이 때 검출된 수위가 기 설정된 설정 수위 이상인 지를 판단(S50)한다. When the rotation of the drum is stopped, the water level sensor 20 is controlled to detect the water level inside the drum (S40), and at this time, it is determined whether the detected water level is equal to or greater than the preset level.

검출된 수위가 설정 수위 미만이면, 구동모터(40)을 제어하여 드럼을 회전(S60)시키고 탈수 행정이 종료할 때까지 통상의 탈수 행정을 수행(S70)한다. If the detected water level is lower than the set water level, the drive motor 40 is controlled to rotate the drum (S60) and the normal dewatering stroke is performed until the dewatering stroke is completed (S70).

한편, 검출된 수위가 설정 수위 이상이면, 에러 출력부(50)를 제어하여 경고음 또는 키 패널의 디스플레이를 통해서 현재 급수밸브(30) 고장이 있음을 표시(S55)함과 더불어 탈수 행정 수행시 과부가 걸릴 수 있음을 사용자에게 경고한다.On the other hand, if the detected water level is higher than the set water level, the error output unit 50 is controlled to display that there is a current water supply valve 30 failure through the warning sound or the display of the key panel (S55) and at the time of performing the dehydration stroke. Warns the user that it may take.

본 발명은 전술한 실시예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수 있다.The present invention is not limited to the above-described embodiments and can be carried out in various modifications within the scope of the technical idea of the present invention.

이와 같이 구성되는 본 발명에 따르면, 탈수 행정 개시 후 설정 시간이 경과 하면 드럼의 회전을 정지시키고 수위를 체크하여 수위가 설정 수위 이상이면 급수밸브의 고장 및 과부하 위험을 경고할 수 있다.According to the present invention configured as described above, if the set time elapses after the start of the dehydration stroke, the drum stops rotating and the water level is checked to warn of a failure of the water supply valve and an overload risk when the water level is higher than the set water level.
