상기와 같은 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.
먼저, 식기세척기(6)의 세척대(1)에 식기를 세척한 상태에서 식기세척 운전신호를 입력하면, 상기 마이콤(가)에서 입력된 신호에 따라 급수밸브(도시되지 않음)를 통해서 분사구(2)를 통해서 물을 분사하면서 소정의 수위가 도달할때까지 분사하면서 식기를 세척하고, 소정의 수위에 도달하면 상기 마이콤(가)을 급수를 중단하고 상기 순환펌프(5)를 구동하면서 배수구(3)를 통해서 배수된 물을 순환관(4)을 통해서 순환시키면서 세척을 시작하게 된다.First, when the dish washing operation signal is input to the washing table 1 of the dishwasher 6 in a state where the dishes are washed, the spray hole (not shown) is supplied through a water supply valve (not shown) according to the signal input from the microcomputer (a). 2) washing the dishes while spraying water until the predetermined water level is reached while spraying water, and when the water level is reached, the microcomputer stops supply of water and drives the circulation pump 5 to discharge the drain ( The water drained through 3) is circulated through the circulation pipe (4) to start the washing.
이때 상기 마이콤(가)에서는 절스폭 변환수단(나)을 통해서 소정의 기준절스를 변환하면서 상기 배수구(3)와 순환펌프(5) 사이 순환관(4)에 장착된 오염도 감지수단(다)인 포토커플리(PC)의 발광부에 신호를 보내 발광을 하게 된다.At this time, the microcomputer (a) is a pollution degree detection means (c) mounted on the circulation pipe (4) between the drain port (3) and the circulation pump (5) while converting a predetermined reference section through the section width conversion means (b) Signal is emitted to the light emitting part of the photocouple (PC) to emit light.
상기와 같이 발광된 빛은 상기 순환관(4)을 순환하는 식기세척된 물을 투과하여 수광부에 전달하고, 수광된 신호는 상기 마이콤(가)에 입력시키게 된다.The light emitted as described above passes through the dish-washed water circulating through the circulation pipe 4 to be transmitted to the light receiving unit, and the received signal is inputted to the microcomputer.
이때 상기 마이콤(가)에서는 상기 순환관(4)을 순환하는 세척된 물의 오염도를 오염도 감지수단(다)으로 감지되어 입력된 신호(즉 오염도)가 기설정된 프로그램에 의하여 소정의 시간(t)동안 제3도의 (a)와 같은신호가 입력되게 되면, 상기 마이콤(가)에서는 기설정된 오염도에 따른 세척시간을 조절하게 되는바, 즉 상기 제3도의 (a)에 도시한 바와같은 신호로 입력 판단되면 상기 마이콤(가)에서 현재 세척되고 있는 식기가 오염도가 약한 식기로 판단하여 세척시간 짧게하면서 세척을 하게되고 상기 오염도 감지수단(다)에서 감지되어 입력되는 신호가 제 3도의 (b)에 도시한 바와같은 신호이면, 세척되고 있는 식기가 오염도가 감하고, 기름기가 많은 식기로 판단하여 이에 해당하는 세척시간을 길게 조절하여 세척을 진행하며, 상기 오염도 감지수단(다)에서 감지되어 입력되는 신호가 제 3도의 (c)에 도시한 바와같은 신호이면, 세척되고 있는 식기가 오염도가 강하지만 잘 씻기는 식기로 판정하여 이에 해당하는 세척시간을 조절하여 제척을 진행하게되므로, 식기세척시 감지되는 오엄도에 따라 세척시간을 가변조절하면서 세척하게 되어 보다 정결하고 위생적인 식기세척을 할 수 있게 되는 것이다.At this time, the microcomputer (a) detects the pollution level of the washed water circulating through the circulation pipe 4 by the pollution degree detecting means (c), and the input signal (that is, the pollution level) is input for a predetermined time t by a preset program. When a signal such as (a) of FIG. 3 is input, the microcomputer (a) adjusts the washing time according to a predetermined pollution level, that is, the signal is determined as shown in (a) of FIG. When the dish is being washed by the microcomputer (a) as a dish with low contamination, the washing time is shortened and the washing time is shortened. The signal detected and input by the contamination detecting means (c) is shown in FIG. 3 (b). If the signal is one, the dish being washed is less pollution, it is determined that the oily tableware, and the washing time is controlled by adjusting the length of time corresponding to this, and the contamination detection means (c) If the detected and input signal is a signal as shown in (c) of FIG. 3, the dish being washed is determined to be dishwashing with high pollution but well washed, and the cleaning time is controlled by adjusting the washing time. The washing time is controlled by varying the washing time according to the severity detected during washing, which enables more clean and hygienic dish washing.
이상에서 설명한 바와같이 본 발명은 식기세척시 세척되는 물의 오염도를 감지하고, 이 감지된 오염도에 따라 세척시간을 가변제어하면서 식기세척을 하도록 함으로써, 불필요하게 세척시간이 길어지는 것을 방지하므로 소비전력을 줄일 수 있음은 물론 보다 깨끗하고, 위생적인 식기세척을 할 수 있는 효과를 제공하게되는 것이다.As described above, the present invention senses the contamination of the water to be washed during dish washing, and by washing the dish while controlling the washing time according to the detected contamination degree, thereby preventing unnecessary washing time, power consumption is reduced. Not only can it be reduced, but it also provides a cleaner, more hygienic dishwashing effect.
