It penetrates to enter the magnetic core 44. When the switch lever 330 is inserted into the magnetic core 44 to charge the pedestal 10, the switch lever 330 operates the cutoff switch 33 so that the power source of the rechargeable battery is not connected to the heating wire 21. When the 10 is placed horizontally and the object is placed on it, the connection switch 34 is operated through the switch lever 340 by the weight so that the power of the rechargeable battery is supplied to the heating wire 21. The temperature controller 22 has a temperature characteristic of about 90 degrees and is connected when it is 90 degrees or less, and shuts off when it is 90 degrees or more, so that the temperature of the hot plate 20 is kept constant. The charging lamp 31 and the charging completion lamp 32 are disposed to be visible from the outside of the pedestal 10.

충전기는 도 3에 설명하면, 충전제어부(40)에 전기선과 스위치와 전원표시기를 내장하고 유도코일(41)을 연결한다. 유도코일(41) 내부 공간에 자기코어(42)를 삽입하고 유도코일(41)에 전류가 공급될 때 그 자력을 유도코일(35)에 원활히 전달하기 위해 자기코어(45)와 자기코어(44)를 자기코어(42)에 부착하고, 받침대(10)를 자기코어(44)에 삽입할 수 있도록 자기코어(43)는 자기코어(43') 방향으로 벌어질 수 있도록 한다. 하나의 충전기에 여러 개의 받침대를 동시에 충전할 수도 있다.Referring to FIG. 3, the charger has an electric line, a switch, a power indicator, and connects the induction coil 41 to the charge control unit 40. The magnetic core 45 and the magnetic core 44 are inserted to insert the magnetic core 42 into the space inside the induction coil 41 and to smoothly transfer the magnetic force to the induction coil 35 when a current is supplied to the induction coil 41. ) Is attached to the magnetic core 42, and the magnetic core 43 can be opened in the magnetic core 43 'direction so that the pedestal 10 can be inserted into the magnetic core 44. You can also charge several pedestals simultaneously in one charger.

전기적 동작을 도 4에 의해 설명하면, 전기코드(PL1)에서 전원스위치(SW1)를 통해 유도코일(L1)에 전원이 공급되고 전원표시기(LED1)는 저항(R1)을 통해 동작한다. 유도코일(L2)에 유도된 전압은 정류기(D1),(D2),(D3),(D4)와 콘덴서(C1)를 통 해 평활된 직류는 트랜지스터(Q1)와 저항(R4)을 통해 충전지(BAT1)에 공급된다. 콘덴서(C1) 양단의 직류전압은 저항(R2)을 통해 트랜지스터(Q2)를 턴온 시키고 트랜지스터(Q2)의 컬렉터(collector)에 연결된 저항(R3)에 의해 트랜지스터(Q1)는 턴온되어 충전전류 제어용 저항(R4)을 거쳐 충전지(BAT1)에 공급한다. 충전지(BAT1)가 충전된 전압이 충분하면 저항(R5),(R6)에 의해 트랜지스터(Q3)가 턴온하여 트랜지스터(Q2)의 전류를 차단하여 트랜지스터(Q1)를 턴어프 시켜 충전을 차단한다. 충전램프(LED2)는 저항(R8)을 통해 트랜지스터(Q2)가 턴온될 때 충전중임을 알리기 위해 켜지고, 충전완료램프(LED3)는 충전전압이 충분하여 트랜지스터(Q3)가 턴온되면 충전 완료를 알리기 위해 켜진다. 차단스위치(SW2)는 받침대가 충전기에 삽입되면 충전지(BAT1)의 전원이 열선(HT1)으로 연결되는 전원을 차단하고, 연결스위치(SW3)는 받침대 위에 올려놓는 물체의 무게에 의하여 열선(HT1)으로 전원이 연결되도록 하고, 온도제어기(VM1)는 바이메탈방식을 사용하여 열선(HT1)의 온도가 설정온도(약90도)보다 높으면 열선(HT1)에 공급되는 전원을 차단하고 설정온도보다 낮으면 열선(HT1)에 전원을 공급하게 한다.Referring to FIG. 4, electric power is supplied to the induction coil L1 through the power switch SW1 in the electric cord PL1, and the power indicator LED1 operates through the resistor R1. The voltage induced in the induction coil L2 is smoothed through the rectifiers D1, D2, D3, D4, and the capacitor C1, and the direct current is charged through the transistor Q1 and the resistor R4. Supplied to (BAT1). The DC voltage across the capacitor C1 turns on the transistor Q2 through the resistor R2, and the transistor Q1 is turned on by the resistor R3 connected to the collector of the transistor Q2 to control the charging current. It is supplied to the rechargeable battery BAT1 via (R4). When the voltage charged with the battery BAT1 is sufficient, the transistor Q3 is turned on by the resistors R5 and R6 to cut off the current of the transistor Q2 to turn off the transistor Q1 to cut off the charge. The charging lamp LED2 is turned on to indicate that charging is performed when the transistor Q2 is turned on through the resistor R8, and the charging completion lamp LED3 indicates charging completion when the transistor Q3 is turned on because the charging voltage is sufficient. Is turned on. When the base switch is inserted into the charger, the cutoff switch SW2 cuts off the power to which the power of the rechargeable battery BAT1 is connected to the hot wire HT1, and the connection switch SW3 is heated by the weight of the object placed on the base. When the temperature of the heating wire HT1 is higher than the set temperature (about 90 degrees), the temperature controller VM1 shuts off the power supplied to the heating wire HT1 by using a bimetal method. It supplies power to the heating wire HT1.
