본 발명은 세척기의 세척제어방법에 관한 것으로서, 특히 식기세척기에서 세척모터가 구동될 경우 세척수의 넘침현상 및 수위감지부의 오동작을 방지하도록 한 세척기의 세척제어방법에 관한 것이다.The present invention relates to a washing control method of the washing machine, and more particularly, to a washing control method of the washing machine to prevent the overflow of the washing water and the malfunction of the water level detection unit when the washing motor is driven in the dishwasher.

제1도는 일반적인 세척기의 세척제어장치에 대한 구성블록도로서, 전체 시스템에 전원을 공급하는 전원부(1)와, 급수 및 배수시 터브내의 세척수위를 감지하는 수위감지부(2)와, 급/배수 밸브 및 세척모터를 구동시키는 부하구동부(3)와, 상기 전원부(1)의 전원을 공급받아 상기 수위감지부(2)와 부하구동부(3)를 제어하는 마이컴(4)으로 이루어진다.1 is a block diagram of a washing control device of a general washing machine, the power supply unit (1) for supplying power to the entire system, the water level detection unit (2) for detecting the water level in the tub during water supply and drainage, A load driver 3 for driving the drain valve and the washing motor, and a microcomputer 4 for controlling the water level sensing unit 2 and the load driving unit 3 by receiving power from the power supply unit 1.

이하, 제2도 및 제3도에 도시된 도면을 참조하여 종래 기술에 따른 세척기의 세척제어방법을 상세히 설명하면 다음과 같다.Hereinafter, the washing control method of the washing machine according to the prior art will be described in detail with reference to the drawings illustrated in FIGS. 2 and 3.

제2도는 종래 기술에 따른 플로우챠트로써, 정상 운전상태일 경우는 제2도 (a)와 같이 전원 인가후 세척모드키를 누르면(S101) 부하구동부(3)에서 배수밸브를 구동하여 잔류하는 세척수를 배수시키고, 급수밸브를 열어(S102) 터브내에 뜨거운 세척수를 정상 세척수위로 도달될 때까지 공급한다(S103).FIG. 2 is a flow chart according to the prior art. In the normal operation state, when the washing mode key is pressed after the power is applied as shown in FIG. 2A (S101), the washing water remaining by driving the drain valve in the load driving unit 3 is shown. Drain, open the water supply valve (S102) and supply the hot wash water in the tub until it reaches the normal washing water level (S103).

상기 세척수가 정상 세척수위까지 도달하면 상기 부하구동부(3)는 급수밸브를 닫고 급수를 종료한다(S104).When the washing water reaches the normal washing water level, the load driving unit 3 closes the water supply valve and ends water supply (S104).

그러면 마이컴(4)은 전체 시스템을 2초 동안 대기한 후 상기 부하구동부(3)에 세척모터를 구동하라는 신호를 입력하여 제3도에 도시된 바와 같이, 비가열시(a) 및 가열시(b)의 본 세척행정을 수행한다(S105).Then, the microcomputer 4 waits the entire system for 2 seconds and inputs a signal to drive the washing motor to the load driving unit 3, as shown in FIG. 3, when not heating (a) and heating (b). Carry out the present washing stroke of (S105).

이 때 세척행정은 뜨거운 세척수를 분사시키는 것이다.At this time, the washing stroke is to spray hot washing water.

한편, 정상 운전중에 도어(Door)를 연 후, 닫았을 경우는 제2도 (b)와 같이 세척기의 세척 운전중에 도어를 열면(S201) 부하구동부(3)의 정지명령에 의해 전체 시스템은 즉시 멈추어 일시 정지상태를 유지하며(S202), 상기 도어를 닫으면 이전 행정이 제3도와 같은 비가열시 및 가열시의 세척모터가 동작하는 세척행정인가를 판단하여 (S203) 마이컴(4)은 전체 시스템을 3초동안 대기시킨 후 상기 부하구동부(3)에 세척모터를 구동하라는 신호를 입력하여 세척행정을 수행하거나(S204) 또는 전체 시스템을 1초동안 대기시킨 후 상기 부하구동부(3)에 해당부하를 구동하라는 신호를 입력하여 이에 대응하는 행정을 수행하고(S205) 종료한다.On the other hand, when the door is opened and then closed during normal operation, when the door is opened during the washing operation of the washing machine as shown in FIG. 2 (b) (S201), the entire system is immediately stopped by the stop command of the load driver 3. Stop and maintain the pause state (S202), and closing the door determines whether the previous stroke is a washing stroke in which the washing motor operates during the non-heating and heating as shown in FIG. 3 (S203) and the microcomputer 4 determines the whole system. After waiting for 3 seconds to perform a washing stroke by inputting a signal to drive the washing motor to the load driver (3) (S204) or after waiting the entire system for 1 second to load the load to the load driver (3) Inputting a signal to drive to perform a corresponding stroke (S205) and ends.

상술한 바와 같이 종래 기술에 따른 세척기의 세척제어방법은 세척모터가 구동되어 터브내에 뜨거운 세척수가 분사되거나 또는 세척기의 도어를 열고 닫은 후, 세척모터가 재구동되어 뜨거운 세척수가 분사되면 터브내의 공기가 급격히 팽창하여 두곳의 토출구로 한꺼번에 배출될 수 없기 때문에, 도어하단부의 틈새로 팽창된 공기와 함께 세척수 누수현상이 발생한다.As described above, in the washing control method of the washing machine according to the related art, after the washing motor is driven and hot washing water is injected into the tub or the door of the washing machine is opened and closed, the washing motor is restarted and hot washing water is sprayed. Since it is rapidly expanded and cannot be discharged at the same time through two outlets, washing water leakage occurs with the air expanded in the gap at the bottom of the door.

또한 수위를 감지하기 위한 수위감지부에도 압력이 전달되어 공급된 세척수보다 훨씬 많은 세척수가 공급된 것으로 오인하여 오감지하는 문제점도 있다.In addition, there is a problem in that the water level detection unit for detecting the water level is misunderstood by the fact that much more washing water is supplied than the supplied washing water.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로, 세척행정시 뜨거운 세척수를 기준수온 이하로 낮추어 공기팽창율을 감소시킴으로써 세척수 누수현상 및 수위감지부의 오동작을 방지하도록 한 세척수의 세척제어방법을 제공함에 목적이 있다.The present invention has been made to solve the above problems, and provides a washing control method of washing water to prevent the leakage of water and the malfunction of the water level detection unit by reducing the rate of air expansion by lowering the hot wash water to less than the reference water temperature during the washing administration. There is a purpose.

또한 세척기 도어가 닫힐 때까지 전체 부하를 정지시키는 제1단계와, 설정온도보다 높은 현 세척수의 세척행정에서 일정시간 간헐 세척한 후 본 세척을 수행하는 제2단계와, 상기 세척행정이외의 행정에서 해당 부하를 구동시키는 제3단계로 이루어짐을 특징으로 한다.In addition, the first step of stopping the overall load until the washing machine door is closed, the second step of performing the main cleaning after a certain time intermittent washing in the washing stroke of the current washing water higher than the set temperature, and in the stroke other than the washing stroke Characterized in that the third step of driving the load.

이하, 제4도 및 제5도에 도시된 도면을 참조하여 본 발명에 따른 세척기의 세척제어방법을 설명하면 다음과 같다.Hereinafter, the washing control method of the washing machine according to the present invention with reference to the drawings shown in FIGS. 4 and 5 are as follows.

제4도는 본 발명에 따른 플로우챠트로써 정상운전 상태일 경우는 제4도 (a)와 같이 전원 인가후 세척모드키를 입력하면(S301) 부하구동부(3)에서 배수밸브를 구동하여 잔류하는 세척수를 배수시키고, 급수밸브를 열어(S302) 터브내에 뜨거운 세척수를 정상 세척수위로 도달될 때까지 공급한다(S303)4 is a flow chart according to the present invention, in the normal operation state, if the washing mode key is input after the power is applied as shown in FIG. 4 (a) (S301), the drain water is driven from the load driving unit 3 to remain in the washing water. To drain the water, open the water supply valve (S302) and supply the hot wash water in the tub until it reaches the normal washing water level (S303)

상기 세척수가 정상 세척수위까지 도달하면 상기 부하구동부(3)는 급수밸브를 닫고,급수를 종료한 후 전체 시스템을 2초 정지하여 일시 대기한다(S304).When the wash water reaches the normal wash water level, the load driving unit 3 closes the water supply valve, and stops the whole system for 2 seconds after the water supply is finished (S304).

이 때 터브내의 세척수 온도를 감지한다.At this time, the temperature of the wash water in the tub is sensed.

그러면 현재 세척수의 온도가 마이컴(4)에 설정된 기준수온(43℃∼47℃)보다 크고, 같은가를 판단하여(S305) 본 세척행정코스로 진행하거나(S307) 또는 세척수 온도를 감소시키기 위해 제5도와 같은 세척모터구동 타이밍으로 간헐세척을 10∼15초 정도 실행한 후(S306) 본 세척행정코스로 진행하여(S307) 세척모드를 종료한다.Then, it is determined whether the temperature of the current wash water is greater than the reference water temperature (43 ° C. to 47 ° C.) set in the microcomputer 4 (S305) and proceeds to the present washing administration course (S307) or to reduce the wash water temperature. After the intermittent washing is performed for about 10 to 15 seconds at the same timing as the washing motor driving timing (S306), the process proceeds to the washing administration course (S307) and ends the washing mode.

한편 정상운전중에 도어(Door)를 연(open) 후 닫았을 경우는 제4도 (b)와 같이 세척기의 세척운전중에 도어를 열면(S401) 부하구동부(3)의 정지명령에 의해 전체 시스템을 즉시 멈추어 일시 정지상태를 유지한다(S402).On the other hand, when the door is opened and closed during normal operation, as shown in FIG. 4 (b), when the door is opened during the washing operation of the washing machine (S401), the entire system is stopped by the stop command of the load driving unit 3. Immediately stop and maintain a pause state (S402).

상기 도어를 닫으면 이전 행정이 세척행정코스인가를 판단하여(S403) 아닐 경우, 마이컴(4)은 전체 시스템을 1초동안 정지시켜 대기시킨 후(S408) 상기 부하구동부(3)에 해당 부하를 구동하라는 신호를 입력하여 이에 대응하는 행정을 수행한다(S409).When the door is closed, it is determined whether the previous stroke is the washing administration course (S403). If not, the microcomputer 4 stops the whole system for one second and waits (S408) to drive the load in the load driving unit 3. To input a signal to perform a corresponding stroke (S409).

또한 세척행정코스일 경우, 전체 시스템을 3초동안 정지시켜 대기시키고(S404) 이 때, 터브내의 세척수 온도를 감지한다.In addition, in the case of the washing administration course, the whole system is stopped for 3 seconds to stand by (S404), at this time, to sense the temperature of the washing water in the tub.

이어, 현재 세척수의 온도가 마이컴(4)에 설정된 기준수온(43℃∼47℃)보다 크고 같은가를 판단하여(S405) 본 세척행정코스로 진행하거나(S407) 또는 세척수 온도를 감소시키기 위해 제5도와 같은 세척모터 구동타이밍으로 간헐세척을 10∼15초 정도 실행한 후(S406) 본 세척행정코스로 진행하여(S407) 세척모드를 종료한다.Subsequently, it is determined whether the temperature of the current wash water is greater than or equal to the reference water temperature (43 ° C. to 47 ° C.) set in the microcomputer 4 (S405), and proceeds to the present washing administration course (S407) or to reduce the wash water temperature. After the intermittent washing is performed for about 10 to 15 seconds with the same washing motor driving timing as in FIG. (S406), the process proceeds to the present washing administration course (S407) and ends the washing mode.

상술한 바와 같이, 본 발명에 따른 세척기의 세척제어방법은 수위감지부에서 정상수위를 이상수위로 오감지하는 현상과, 도어 하단부로 세척수가 누수되는 현상을 제거하여 원활하고 안정된 세척행정을 진행하는 효과가 있다.As described above, the washing control method of the washing machine according to the present invention removes a phenomenon in which the normal water level is detected as an abnormal water level in the water level detection unit and a phenomenon in which the water is leaked to the lower part of the door to proceed a smooth and stable washing operation.
