Attach the electric current sensor to the heater of the kettle, and when the kettle is placed on the fixed plate, the electric circuit is supplied to the internal circuit. The electric kettle is switched on and the lamp is turned on while the electric heater is flowing. When the water boils and detects that the current flowing in the heater of the kettle is cut off, and relates to generating a melody for a certain time.
종래의 주전자의 경보기는 공기압력을 이용한 것으로 음색이 부드럽지 못한 등의 문제점이 있었다.The alarm of the conventional kettle has a problem that the tone is not smooth as using the air pressure.
본 고안은 전기한 문제점을 해결하기 위하여 안출한 것으로, 전류감지부분은 유도코일을 배선에 삽입하여 전류가 흐를 때 유도되는 미세신호를 에이디변환기(A/D CONVERTER)를 사용하여 전류의 흐름을 판단하고, 전원공급부의 직류정전압은 5.6볼트 정도 되도록하기 위해 콘덴서(C1)의 내부임피던스를 2.7킬로옴(KΩ)정도인 것을 사용하고 제너다이오드(D2)는 5.6볼트를 사용하고, 경보음은 마이크로컨트롤러(MCU)의 프로그램으로 원하는 멜로디를 발생하여 스피커(SP)를 울린다.The present invention was devised to solve the above-mentioned problems, and the current sensing part inserts an induction coil into the wiring to determine the flow of current using an A / D converter using a micro signal induced when current flows. In order to ensure that the DC constant voltage of the power supply is about 5.6 volts, the internal impedance of the capacitor C1 is about 2.7 kiloohms (K Ω ), the zener diode (D2) uses 5.6 volts, and the alarm sound is micro. The program of the controller (MCU) generates the desired melody to ring the speaker (SP).

이하, 본 고안의 실시의 예를 첨부된 도면을 통해 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도면을 참조하면, 본 고안은 전기주전자의 고정판 내부에 장착되며 입력표시부분은 전원코드가 연결되는 부분이고 출력표시부분은 주전자의 히터가 연결되는 부분이며 스위치(SW)는 고정판 위에 주전자가 안착되면 온(ON) 되여 전원공급부(100)에 교류전압이 공급된다.Referring to the drawings, the present invention is mounted inside the fixing plate of the electric kettle, the input display part is the part to which the power cord is connected, the output display part is the part to which the heater of the kettle is connected, and the switch (SW) when the kettle is seated on the fixing plate. When turned on (ON), an AC voltage is supplied to the power supply unit 100.
전원공급부(100)는 내부임피던스 2.7킬로옴(KΩ) 정도의 콘덴서(C1)와저항(R1)과 정류다이오드(D1)에 의해 정류된 전압은 5.6볼트 제너다이오드(D2)와 콘덴서(C2)에 의해 5.6볼트의 직류전압을 유지하며 동작회로의 필요한 전원이 된다.The power supply unit 100 has a voltage of 5.6 volt zener diode (D2) and capacitor (C2) rectified by a capacitor (C1), a resistor (R1), and a rectifier diode (D1) having an internal impedance of about 2.7 kiloohms (K Ω ). This maintains a DC voltage of 5.6 volts and becomes the required power source for the operating circuit.
전류감지부(300)는 주전자의 히터측으로 연결되는 배선에 전류감지센서(SENS)를 삽입하여 에이터변환기(A/D CONVERTER)가 내장된 마이크로 컨트롤러(MCU)에 연결하고, 마이크로컨트롤러(MCU)는 유도되는 전압의 변화를 비교하여 주전자의 히터가 작동하는지를 판단한다.The current detection unit 300 is connected to the microcontroller (MCU) with a built-in A / D converter by inserting a current sensor (SENS) in the wiring connected to the heater side of the kettle, the microcontroller (MCU) The change in induced voltage is compared to determine if the heater of the kettle is working.
육안표시부(400)는 주전자의 히터에 전류가 흐르는 동안 램프(LED)를 켜서 물을 끓이고 있음을 육안으로 확인할 수 있도록 한다.The visual display unit 400 turns on a lamp (LED) while a current flows in the heater of the kettle to visually confirm that the water is boiling.
메로디발생부(500)는 주전자의 히터에 전류가 흐른 후 차단되면 약 10초정도 멜로디를 발생하며 트랜지스터(Q1)를 구동하여 스피커(SP)를 울리게 한다.The melody generating unit 500 generates a melody for about 10 seconds when the electric current flows through the heater of the kettle and drives the transistor Q1 to ring the speaker SP.
이상에서 설명된 바와같이 본고안은 전기주전자 사용시 물이 끓었다는 상태를 아름다운 멜로디로 들을 수 있도록 하고, 물을 끓이는 동안에는 램프를 켜서 주전자의 작동상태를 육안으로 쉽게 식별할 수 있는 효과를 얻을 수 있다.As described above, this proposal allows you to listen to the beautiful melody of water boiling when you use the electric kettle, and turn on the lamp while boiling the water to obtain the effect that can be easily visually identified. .
