이하, 상기와 같이 구성된 식기세척기의 세척제어방법의 동작과정 및 작용효과를 설명한다.Hereinafter, an operation process and an effect of the washing control method of the dish washing machine configured as described above will be described.

도 3은 본 발명에 의한 식기세척기의 세척제어방법의 동작 흐름도이다.3 is an operation flowchart of a washing control method of the dish washing machine according to the present invention.

세척하고자 하는 식기를 세척조(20) 내부의 식기바구니(22)에 수납한 상태에서 사용자가 세척코스와 세척수온도, 헹굼 추가 등의 운전정보를 선택하면, 사용자가 선택한 운전정보가 입력부(100)를 통해 제어부(110)에 입력된다.When the user selects driving information such as a washing course, washing water temperature, and rinsing while storing the dishes to be washed in the dish basket 22 inside the washing tank 20, the driving information selected by the user is displayed on the input unit 100. It is input to the control unit 110 through.

따라서, 제어부(110)는 입력부(100)로부터 입력된 운전정보에 따라 세척행정을 진행하기 시작하는데, 먼저 예비세척행정인가를 판단한다(S200).Therefore, the control unit 110 starts the washing operation according to the operation information input from the input unit 100, and first determines whether the preliminary washing operation (S200).

예비세척행정인 경우 제어부(110)는 예비세척행정의 추가횟수(Nw)를 0으로 클리어시킨 후(S202), 구동부(120)를 통해 급수밸브(122)를 제어함에 따라 예비세척에 필요한 세척수가 세척수 공급홀(미도시)을 통해 세척조(20) 내부로 공급되기 시작한다(S204).In the case of the preliminary washing stroke, the control unit 110 clears the additional number Nw of the preliminary washing stroke to 0 (S202), and then controls the water supply valve 122 through the driving unit 120 to wash water necessary for the preliminary washing. It starts to be supplied into the washing tank 20 through the washing water supply hole (not shown) (S204).

상기 세척조(20) 내부로 공급되는 세척수는 세척조(20) 하부에 마련된 섬 프(42) 내부로 유입된 후, 섬프(42) 내부 세척펌프(46)의 펌핑작용에 의해 유입된 세척수가 제1 및 제2공급관(28a,28b)을 통해 상단 분사노즐(26a)과 중단 분사노즐(26b) 및 하단 분사노즐(26c)로 이동되어 식기바구니(22)에 수납된 식기에 세척수가 고압으로 분사되는 예비세척을 진행하기 시작한다(S206).After the washing water supplied into the washing tank 20 flows into the sump 42 provided below the washing tank 20, the washing water introduced by the pumping action of the washing pump 46 inside the sump 42 is firstly introduced. And the second injection pipe (28a, 28b) is moved to the upper injection nozzle (26a), the interruption injection nozzle (26b) and the lower injection nozzle (26c) and the washing water is sprayed at a high pressure to the dishes stored in the dish basket 22 The preliminary washing starts to proceed (S206).

예비세척이 진행되면, 세척수 뿐만 아니라 식기에 묻은 오염물도 세척수에 의해 세척되어 섬프(42)로 유입되므로 섬프(42) 내부에 설치된 탁도센서(44)는 포토 커플러를 이용하여 발광부(44a)에서 발광된 빛이 식기 세척된 세척수를 투과하여 수광부(44b)에 수광되는 광 신호를 제어부(110)에 입력하여 예비세척행정 중에 식기 세척된 세척수의 탁도(Tw)를 검출한다(S208).When the preliminary washing is performed, not only the washing water but also the contaminants on the tableware are washed by the washing water and introduced into the sump 42. Thus, the turbidity sensor 44 installed inside the sump 42 is formed at the light emitting unit 44a using a photo coupler. The emitted light passes through the dishwashing wash water and inputs an optical signal received by the light receiving unit 44b to the controller 110 to detect the turbidity Tw of the dishwashing wash water during the preliminary washing operation (S208).

따라서, 상기 제어부(110)는 탁도센서(44)에 의해 검출된 세척수의 탁도(Tw)를 미리 정해진 기준탁도(Ts; 예비세척의 추가 진행여부를 판단하기 위한 세척수의 탁도)와 비교하여(S210), 상기 검출된 세척수의 탁도(Tw)가 기준탁도(Ts) 미만이면 배수펌프(48)의 동작에 따라 오염물이 포함된 세척수를 배수관(50)을 통해 배수시키고(S212) 예비세척을 종료한다.Accordingly, the control unit 110 compares the turbidity Tw of the washing water detected by the turbidity sensor 44 with a predetermined reference turbidity Ts (the turbidity of the washing water to determine whether further preliminary washing is performed) (S210). ), When the detected turbidity Tw of the wash water is less than the reference turbidity Ts, the washing water containing contaminants is drained through the drain pipe 50 according to the operation of the drain pump 48 (S212), and the preliminary washing is terminated. .

한편, 상기 비교결과 검출된 세척수의 탁도(Tw)가 기준탁도(Ts) 이상이면 배수펌프(48)의 동작에 따라 오염물이 포함된 세척수를 배수관(50)을 통해 배수시키고(S214) 예비세척을 추가로 1회 더 진행하기 위해 예비세척행정의 추가횟수(Nw)를 1만큼 증가시킨다(S216).On the other hand, if the turbidity (Tw) of the wash water detected as a result of the comparison is more than the reference turbidity (Ts) according to the operation of the drain pump 48 drains the wash water containing contaminants through the drain pipe 50 (S214) and pre-washing In order to proceed one more time, the additional number Nw of the preliminary washing stroke is increased by one (S216).

이후, 제어부(110)는 증가된 예비세척행정의 추가횟수(Nw)를 미리 정해진 일정횟수(Ns)와 비교하여(S218) 상기 예비세척행정의 추가횟수(Nw)가 일정횟수(Ns) 이하인 경우 일정횟수(Ns)에 도달할 때까지 예비세척행정을 추가로 진행하기 위해 상기 S204로 피드백되어 이후의 동작을 계속한다.Subsequently, the controller 110 compares the increased number of additional preliminary washing strokes Nw with a predetermined predetermined number of times Ns (S218) when the additional number of preliminary washing strokes Nw is less than or equal to a predetermined number of times Ns. In order to proceed with the preliminary washing stroke further until the predetermined number Ns is reached, it is fed back to S204 to continue the subsequent operation.

이때, 제어부(110)는 추가로 진행하는 예비세척행정 중에도 세척수의 탁도(Tw)를 검출하여 검출된 세척수의 탁도(Tw)가 기준탁도(Ts) 미만이면 예비세척을 종료하고, 상기 검출된 세척수의 탁도(Tw)가 기준탁도(Ts) 이상이면 예비세척을 추가로 1회 더 진행하는 과정을 반복하여 오염이 심한 경우 세척이 확실이 이루어질 수 있도록 한다.At this time, the controller 110 detects the turbidity Tw of the washing water even during the further preliminary washing stroke, and ends the preliminary washing if the detected turbidity Tw is less than the reference turbidity Ts. If the turbidity (Tw) is higher than the reference turbidity (Ts), repeat the preliminary washing process once more to ensure that the cleaning is possible in case of severe contamination.

한편, 상기 비교결과 예비세척행정의 추가횟수(Nw)가 일정횟수(Ns)를 초과한 경우 예비세척행정을 더 이상 진행하지 않고 예비세척을 종료한다.On the other hand, when the additional number Nw of the preliminary washing stroke exceeds the predetermined number Ns as a result of the comparison, the preliminary washing is terminated without further proceeding with the preliminary washing stroke.
