상술한 바와같이 구성된 본 발명의 작용 및 효과를 제 3 도를 근거로 상세히 설명하면 다음과 같다.The operation and effects of the present invention configured as described above will be described in detail with reference to FIG.
먼저, 본 회로에 전원이 인가되면 마이컴(50)은 초기화상태를 (S100)거친후 사용자에 의한 농도입력대기를 한다(S101). 이는, 사용자의 다양한 입맛에 따라 입력할 수 있는 바, 즉 농도선택입력부(40)를 통해 진하게 또는 연하게 등을 입력하여 주면 이에 마이컴(50)은 입력단(P3)을 통해 입력받아 농도를 결정하고, 이어 커피통(1)에 커피가루가 투입됨에 비해 마이컴은 커피량을 감지한다(S102).First, when power is applied to the circuit, the microcomputer 50 goes through the initialization state (S100) and waits for the concentration input by the user (S101). This can be input according to the various tastes of the user bar, that is, through the concentration selection input unit 40, such as dark or light input to the microcomputer 50 is input through the input terminal (P3) to determine the concentration and Then, compared to the coffee powder is put into the coffee container 1, the microcomputer detects the amount of coffee (S102).
즉, 제1중량센서(10)에서 커피가루의 투입에 의한 커피통(1)의 중량증가를 A/D컨버터(30)를 통한 디지탈한 전위신호가 입력단(P1)에 입력되므로 이에 마이컴(50)은 커피량의 중량을 측정, 인식케 된다.That is, since the potential signal of the digital weight increase of the coffee container 1 by the input of the coffee powder from the first weight sensor 10 through the A / D converter 30 is input to the input terminal P1, the microcomputer 50 ) Measures and recognizes the weight of coffee.
이와같이 입력된 조건들을 세트한 상태에서 마이컴(50)은 입력된 농도 및 커피량에 따른 물증발량을 산출결정한다(S103). 산출된 증발량에 따라 마이컴(50)은 증발제어토록 하는데, 이때 우선 수조의 물량을 측정하도록 하여 (S104) 물부족여부를 판단한다(S105). 그 제어동작은, 제2중량센서(20)에서 수조내의 물량에 의한 수조(2)의 중량 증가를 A/D컨버터(30)를 통한 디지탈한 전위신호가 입력단(P2)에 입력되므로 이에 마이컴(50)은 물의 중량을 측정, 인식케 된다. 여기서, 산출된 물량과 동일하면 마이컴(50)은 출력단(P6)에 고전위를 인가하여 히터구동부(80)를 구동시켜 히터로서 수조 내의 물을 증발토록 하되(S106), 초기에 결정된 증발량에 도달한 상태이면(S107) 히터구동부(80)를 제어하여 히터를 오프토록 함으로서(S108), 설정된 농도에 따라 물량이 토출되도록 한다.In this state of setting the input conditions, the microcomputer 50 calculates and determines the water evaporation amount according to the input concentration and the amount of coffee (S103). The microcomputer 50 is to control the evaporation according to the calculated amount of evaporation, in which case the amount of water in the tank is first measured (S104) to determine whether the water is insufficient (S105). In the control operation, since the potential signal obtained by digitally increasing the weight of the water tank 2 by the amount of water in the water tank by the second weight sensor 20 is input to the input terminal P2, the microcomputer ( 50) measures and recognizes the weight of water. Here, if it is equal to the calculated quantity, the microcomputer 50 applies a high potential to the output terminal P6 to drive the heater driving unit 80 to evaporate the water in the tank as a heater (S106), and reaches the initially determined amount of evaporation. If it is in one state (S107) by controlling the heater driving unit 80 to turn off the heater (S108), the amount of water to be discharged according to the set concentration.
한편, 산출된 물량에 미치지 못한 상태인 즉 물부족으로 판단되면 마이컴(50)은 경보부(60)와 표시부(70)에 하이전위를 인가하족을 알리도록 하는데(S109)(S110), 그 제어동작은 먼저 경보부(60)는 저항(R1)을 거친 하이전위가 트랜지스터(Q1)를 도통시켜 부져(B)가 동작되도록 하며, 표시부(70)는 인버터(I1)에 의해 반전된 신호로 표시램프(LED)가 점등되도록 한다.On the other hand, if it is determined that the water is short of the calculated quantity, that is, the microcomputer 50 to inform the alarm unit 60 and the display unit 70 to inform the application of the high potential (S109) (S110), the control operation First, the alarm unit 60 causes the high potential through the resistor R1 to conduct the transistor Q1 so that the buoy B is operated, and the display unit 70 is a signal inverted by the inverter I1. LED) lights up.
이는, 결국 외부에서 표시램프(LED)와 부져(B)음으로써 입력된 농도조절이 이루어 졌는가를 판단할 수 있게 된다.This, in turn, it is possible to determine whether the input density adjustment is made by the display lamp (LED) and the buzzer (B) from the outside.
이와같이 본 발명은 커피의 농도를 조절함에 있어서, 설정된 농도를 기준으로 한 커피가루의 첨가량에 따른 정확한 농도가 이루어지는 이점이 있다.As described above, the present invention has an advantage in that the concentration of the coffee is precisely adjusted according to the amount of coffee powder added based on the set concentration.
이상에서 설명은 본 발명의 일실시예에 불과하며, 본 발명의 그 구성 요지 범위내에서 얼마든지 변경이 가능하다.The above description is only one embodiment of the present invention, and any change may be made within the scope of the present invention.
