종래의 식기세척기는 사용자가 씻고자하는 식기의 오염정도에 따라 세정시간을 일일이 조작하여 입력시켜야 할뿐만 아니라, 세척기의 사용에 익숙치 않으면 실지 세척에 필요한 시간보다 짭게하여 완전히 세척이 되지 않거나, 반대로 시간을 너무 길게하여 불필요한 전력소비를 낭비하는 경우가 발생하며, 또한 사용자가 설정할 수 있는 세정시간도 몇가지 되지 않아서 적절한 시간을 맞추기 어렵고 조작하는 것도 어려운 문제점이 있다.Conventional dishwashers not only have to input the cleaning time manually according to the degree of contamination of the dishes that the user wants to wash, but also are not completely washed by making the washing time shorter than the time required for the actual washing if the user is unfamiliar with the use of the washing machine. It is too long to waste unnecessary power consumption, and also the cleaning time that can be set by the user is not a few, it is difficult to adjust the appropriate time and there is also a difficult problem to operate.

DC voltage generator 2 consisting of (BR), transistors (Q 6- Q 9 ), resistors (R 14- R 21 ), cleaning detection sensor (L), coupling capacitors (C 2 , C 3 ) Cleaning condition sensing unit 3 consisting of an orthopedic flip-flop (FF), an absolute humidity sensor (HS) made of an open thermistor and a completely dry air, and an absolute humidity sensor (HS) Acid amplifier (OP 1, OP 2), operational amplifier (OP 4), resistance operational amplifier for comparing for comparing the output of the voltage with the operational amplifier (OP 3) is set delayed by (R 27, R 28) ( OP 4) and Absolute humidity sensor An absolute humidity sensor 4 consisting of a balance calibration resistor (R 29- R 33 ), a thermistor (TH) for detecting water temperature, an operational amplifier (OP 5 ) that is a voltage follower, and a comparator with hysteresis. A temperature sensing unit 5 composed of amplifiers OP 6 and OP 7 , a microcomputer 6 composed of input / output terminals, a temperature sensing unit 5 composed of level sensing switches SW 1 to SW 2 , and the like. , on each input and output terminals microcomputer 6 and the water level sensing switch configured (SW 1 -SW 2) and pull-down (pulldown) resistors (R 42, R '42) and the water level sensing unit (7) consisting of, administration user wants It consists of a key input section (8) which informs the microcomputer (6) of information about.

제2도, 제3도 제4도 제5도를 참조하면, 먼저, 사용자가 키 입력부(8)를 통하여 표준이나 강세정을 눌렀다면, 제4도의 타이밍도와 같은 행정이 행해지게 된다.Referring to FIG. 2, FIG. 3, FIG. 4, and FIG. 5, first, if the user presses the standard or the strong washing through the key input unit 8, the stroke as shown in FIG. 4 is performed.

즉, 배수펌프(DP)가 작동하여 수위 스위치(SW2)가 개방되고 마이크로 컴퓨터 입력단자(I6)가 로우상태가 되면 배수가 끝난상태가 되고, 이때부터 마이크로 컴퓨터 출력단자(O2)가 하이상태가 되어 릴레이(RY2)의 코일을 여자하면, 릴레이(RY2)의 접점이 단락되어 솔레노이드(S)가 작동하며, 밸브가 열려 식기세척기 용기내의 급수가 되게 되는데 이는 수위스위치(SW1)가 단락되어 마이크로 컴퓨터 입력단자(I4)가 하이레벨이 될때까지 계속된다.That is, when the drain pump DP is operated and the water level switch SW 2 is opened and the microcomputer input terminal I 6 becomes low, the drainage is finished. From this time, the microcomputer output terminal O 2 is If then at a high state woman the coil of the relay (RY 2), the contact of the relay (RY 2) is short-circuited solenoid (S) is activated, and the valve is open, there is presented the water in the dishwasher vessel which water level switch (SW 1 ) Is short-circuited until the microcomputer input terminal I 4 becomes high level.

입력단자(I4)가 하이상태가 되면, 급수가 완료되어 급수밸브의 작동은 마이크로 컴퓨터 출력단자(O2)가 로우 레벨로 변함에 릴레이(RY2)의 접점이 떨어지므로 자연히 멈추게 된다.When the input terminal I 4 becomes high, the water supply is completed and the operation of the water supply valve stops naturally because the contact point of the relay RY 2 falls as the microcomputer output terminal O 2 changes to a low level.

그다음으로 출력단자(O3)가 하이레벨로 변하여 릴레이(RY3)를 여자시키면 세정펌프가 작동되어서 실지 식기 세척작업이 행해진다.Next, when the output terminal O 3 changes to a high level and the relay RY 3 is excited, the washing pump is operated to perform the actual dish washing operation.

그러나 사용자가 기름 세정키를 초기에 선택하였다면, 제5도와 같이 급수완료후에 히터(H)를 가동시켜 물이 어느 일정온도(기름의 대·소에 따라 온도가 달라짐)에 도달한 후에야 세척작업이 행해지게 된다.However, if the user initially selects the oil cleaning key, as shown in Fig. 5, after the water supply is completed, the heater (H) is operated so that the cleaning operation is not performed until the water reaches a certain temperature (temperature varies depending on the size of the oil). Will be done.

그다음에 세정상태감지부(3)의 플립플롭(FF)의 출력(

Figure kpo00001
)이 마이크로 컴퓨터의 입력단자(T5)로 신호가 입력되는데, 세척작업은 로우레벨이 어느정도 일정시간 이상 계속될때까지 행해진다.Next, the output of the flip-flop FF of the cleaning state detection unit 3 (
Figure kpo00001
The signal is input to the input terminal T 5 of the microcomputer, and the cleaning operation is performed until the low level continues for some time or more.

이때 식기세척으로 인해 물이 더러워져 세정센서에서는 광발산 다이오드(LD)에서 발산되는 빛이 포토트랜지스터(LTR)에 미치지 못하게 되므로 제2도에서와 같은 레벨이 된다.At this time, the water becomes dirty due to the dish washing, so that the light emitted from the light emitting diode LD does not reach the phototransistor LTR in the cleaning sensor, thereby achieving the same level as in FIG. 2.

따라서, 마이크로 컴퓨터(6) 출력단자(O3)가 로우가 되어 세정행정을 멈추게 되면, 출력단자(Q2,Q3)를 상기한 바와 같이 작동시켜서 헹구기 행정이 들어가게 되는데, 이때 시간은 세정상태 감지부(3)의 출력에 관계없이 미리 설정된 일정시간동안 행하여 진다.Therefore, when the microcomputer 6 output terminal O 3 becomes low and stops the washing stroke, the rinsing stroke enters by operating the output terminals Q 2 and Q 3 as described above, wherein the time is in the washing state. Irrespective of the output of the sensing section 3, the operation is performed for a predetermined time.

마이크로 컴퓨터(6)의 출력단자(O4)를 하이 레벨로 하여 배수시키며, 상기한 바와 같이 수위 스위치(SW2)가 로우레벨이 될때까지 배수가 계속되고, 배수가 끝나면 히터(H)가 가동되어 식기 건조작업에 들어가 절대습도 감지부(4)의 출력이 하이레벨이 될때까지 식기를 건조시키게 된다.The output terminal O 4 of the microcomputer 6 is drained to a high level, and drainage is continued until the water level switch SW 2 becomes a low level as described above, and the heater H is activated when the drainage is completed. Into the dish drying operation, the dish is dried until the output of the absolute humidity detecting unit 4 reaches a high level.

개방형 써미스터와 밀폐형 써미스터로 이루어진 절대습도 센서(HS)는, 제3도에서 보는 바와 같이 고정저항(R23,R24)으로 브릿지 회로를 구성하고, 각각의 중점을 볼테지 플로워(OP1,OP2)를 통하여 증폭시켜서, 미리 정해진 레벨과 비교하는데, 이때의 비교치는 최초의 설계자가 실험에 의해서 정할 수 있다.An absolute humidity sensor (HS) composed of an open thermistor and sealed thermistor, third degree viewing fixed resistor (R 23, R 24) to configure a bridge circuit, if bolte to each of the middle point follower (OP 1, and as described in the OP Amplify through 2 ) and compare with a predetermined level. The comparison value can be determined by the first designer by experiment.

절대습도 감지의 원리는 식기에 물이 있는 수분이 절대습도 센서에 접촉되어 기화열이 발생하므로 완전 건조공기로 밀폐되어 있는 밀폐형 써미스터보다 개방형 써미스터의 저항이 커지게 되는데 건조가 될수록 수분이 적어져서 저항(R22,R24)의 중점보다 전위차가 작아진다.The principle of absolute humidity detection is that the moisture in the tableware comes into contact with the absolute humidity sensor to generate vaporization heat, so that the resistance of an open thermistor becomes greater than that of a closed thermistor, which is completely sealed with dry air. The potential difference is smaller than the midpoint of R 22 and R 24 ).

또 습기가 많으면 많을수록 전위차가 커진다.The more moisture there is, the greater the potential difference is.

그러므로 히터가 가열됨에 따라 습기가 증발되어 밀폐형 써미스터와 개방형 써미스터의 저항치가 거의 같을 때 식기가 완전히 건조되어서 자동식기세척 건조행정이 끝난다. 저항(R29-R33)은 식기 세척기의 초기동작과 동시에 절대습도 센서의 초기상태 조정용이며, 온도감지부(5)에서 비교기(OP6,OP7)를 이원화한 것은 기름기가 많고 적음에 따라 수온을 달리하면 세정효과를 내기 위함이다.Therefore, when the heater is heated, the moisture is evaporated and when the resistance of the hermetically sealed thermistor and the open thermistor is about the same, the dishes are completely dried and the automatic dishwashing drying process is completed. Resistor (R 29- R 33 ) is for adjusting the initial state of absolute humidity sensor at the same time as the initial operation of the dishwasher, the duality of the comparators (OP 6 , OP 7 ) in the temperature sensing unit 5 is greasy and less Different water temperature is for cleaning effect.

상기한 전자동 식기세척기는 최초의 배수동작에서 건조동작까지 원터치 전자동으로 이루어지도록 구성되어 사용자의 조작이 간편해졌으며, 적절한 작동시간 조절로 에너지를 절약할 수 있다.The automatic dishwasher is configured to be one-touch fully automatic from the first drain operation to the drying operation to simplify the user's operation, it can save energy by adjusting the appropriate operating time.
