Description

전자렌지의 팬모터 구동회로Microwave fan motor driving circuit

본 고안은 전자렌지의 팬모터 구동회로에 관한 것으로, 좀더 상세하게는 마그네트론의 동작 주기에 따라 팬모터를 주기적으로 동작시켜 팬모터의 소비전력을 감소시키고, 팬모터의 수명을 연장시킬 수 있는 전자렌지의 팬모터 구동회로에 관한 것이다.The present invention relates to a fan motor driving circuit of a microwave oven, and more specifically, to operate the fan motor periodically according to the operation period of the magnetron to reduce the power consumption of the fan motor and to extend the life of the fan motor. It relates to a fan motor driving circuit of the range.

일반적으로, 전자렌지는 열전도 및 열복사등을 이용한 종래의 외부 가열방식의 조리 기구와는 달리 마그네트론이라는 마이크로파 발진관에 고압전기를 가하여 마이크로파를 발생시키고, 이러한 마이크로파를 음식물에 가하여 음식물을 가열조리한다.In general, a microwave oven generates microwaves by applying a high-voltage electric power to a microwave oscillation tube called magnetron, unlike a conventional cooking apparatus of a conventional external heating method using heat conduction and heat radiation.

상기와 같이 음식물에 마이크로파를 가하면 음식물을 구성하고 있는 분자들이 빠른 속도로 회전함에 따라 많은 마찰열이 발생하게 되고, 이 열에 의하여 식품을 가열조리하는 것이다.When microwave is applied to the food as described above, a lot of frictional heat is generated as the molecules constituting the food rotate at a high speed, and the food is heated and cooked by this heat.

상기와 같은 원리에 의해 동작되는 전자렌지 구동회로는 도1에 도시된 바와 같이, 노이즈필터와, 저압변압기(LVT), 고압변압기(HVT) 및, 각종 릴레이로 이루어진 전원부(1)와, 마그네트론(2), 팬모터(3), 램프, 회전접시구동모터 등을 포함하는 기타부하부(4), 입력키이(5) 및, 제어부(6)로 이루어져 있다.As shown in FIG. 1, the microwave driving circuit operated according to the above principle includes a noise filter, a low voltage transformer (LVT), a high voltage transformer (HVT), a power supply unit 1 consisting of various relays, and a magnetron ( 2) a fan motor 3, a lamp, a rotational plate driving motor, etc., including other load portion 4, the input key (5), and the control unit (6).

상기 전원부(1)는 외부로부터 인가된 상용교류전원을 상기 제어부(6)의 제어에 의해 마그네트론(2), 팬모터(3), 기타부하부(4)에 공급하여 전자렌지를 동작시킨다.The power supply unit 1 supplies a commercial AC power applied from the outside to the magnetron 2, the fan motor 3, and the other load unit 4 under the control of the control unit 6 to operate the microwave oven.

상기 마그네트론(2)은 상기 전원부(1)로부터 고압을 인가받아 마이크로파를 발생시키고, 이 마이크로파가 조리실내의 음식물에 가해져서 음식물을 가열조리한다.The magnetron 2 receives microwaves from the power supply unit 1 to generate microwaves, and the microwaves are applied to food in the cooking chamber to heat food.

상기 팬모터(3)는 상기 마그네트론(2)이 고온으로 상승하는 것을 방지하기 위해 상기 마그네트론(2)에 송풍하여 마그네트론(2)에서 발생한 열을 식힌다.The fan motor 3 cools the heat generated by the magnetron 2 by blowing the magnetron 2 to prevent the magnetron 2 from rising to a high temperature.

그리고, 상기 제어부(6)는 사용자가 상기 입력키이(5)를 통해 입력한 조리선택명령에 따라 전원부(1) 내에 구비되어 있는 각종 릴레이(도시하지 않음) 예를 들어, 메인릴레이, 파워릴레이. 인러쉬릴레이등을 제어하여 마그네트론(2), 팬모터(3), 기타부하부(4)의 구동을 제어함으로써, 전자렌지의 운전을 제어한다.In addition, the control unit (6) is a variety of relays (not shown) provided in the power supply unit 1 according to the cooking selection command input by the user through the input key (5), for example, main relay, power relay. The operation of the microwave is controlled by controlling the inrush relay and the like to control the driving of the magnetron 2, the fan motor 3, and the other load portion 4.

그러나, 상기와 같은 종래의 전자렌지 구동회로는, 음식물 조리시 마그네트론이 일정주기로 구동되는 반면에, 팬모터는 마그네트론의 마이크로파발진 여부에 관계없이 조리시작시부터 조리 종료시 까지 일정한 회전속도로 구동시켰다.However, in the conventional microwave driving circuit as described above, the magnetron is driven at a constant cycle during food cooking, while the fan motor is driven at a constant rotation speed from the start of cooking to the end of cooking regardless of whether the magnetron is microwaved or not.

따라서, 마그네트론의 온도 상승에 능동적으로 대처하지 못하고 필요 이상으로 팬 모터가 구동됨으로써, 팬모터의 소비전력이 클뿐만 아니라 팬모터의 수명이 감소되는 문제점이 있었다.Therefore, since the fan motor is driven more than necessary without actively coping with the temperature increase of the magnetron, the power consumption of the fan motor is large and the life of the fan motor is reduced.

본 고안은 상기와 같은 종래의 제 문제점을 해소하기 위한 것으로, 마그네트론의 출력에 따라 팬모터를 주기적으로 동작시켜, 팬모터의 소비전력을 감소시킴과 동시에 팬모터의 수명을 연장시킬 수 있는 전자렌지의 팬모터 구동회로를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems of the prior art, by operating the fan motor periodically according to the output of the magnetron, reducing the power consumption of the fan motor and at the same time can extend the life of the fan motor. The purpose of the present invention is to provide a fan motor driving circuit.

이러한 목적을 달성하기 위한 본 고안에 따른 전자렌지의 팬모터 구동회로는, 팬모터에 전원을 선택적으로 공급하기 위한 릴레이와, 마그네트론을 연속적으로 구동시킬 때는 팬모터가 연속적으로 구동되도록 상기 릴레이를 제어하고, 마그네트론을 주기적으로 구동시킬 때는 팬모터가 주기적으로 구동되도록 상기 릴레이를 제어하는 제어부를 포함하여 구성된 것을 특징으로 한다.The fan motor driving circuit of the microwave oven according to the present invention for achieving this purpose, the relay for selectively supplying power to the fan motor, and when the magnetron is continuously driven to control the relay so that the fan motor is continuously driven And, when driving the magnetron periodically, it characterized in that it comprises a control unit for controlling the relay so that the fan motor is driven periodically.

도2는 본 고안에 따른 전자렌지 구동회로의 개략적인 블록 구성도로서, 본 고안에 따라 전자렌지 구동회로는, 노이즈필더와, 저압변압기(LVT), 고압변압기(HVT) 및, 각종 릴레이로 이루어진 전원부(1)와, 마그네트론(2), 팬모터(3), 램프, 회전접시구동모터 등을 포함하는 기타부하부(4), 입력키이(5), 제어부(7) 및, 릴레이(8)로 이루어져 있다.2 is a schematic block diagram of a microwave driving circuit according to the present invention, the microwave driving circuit according to the present invention, a noise filter, a low voltage transformer (LVT), a high voltage transformer (HVT), and various relays Other load part 4, input key 5, control part 7 and relay 8 including power supply part 1, magnetron 2, fan motor 3, lamp, rotary plate driving motor, etc. Consists of

상기 전원부(1)는 외부로부터 인가된 상용교류전원을 상기 제어부(7)의 제어에 의해 마그네트론(2), 팬모터(3), 기타부하부(4)에 공급하여 전자렌지를 동작시키도록 되어 있다.The power supply unit 1 supplies a commercial AC power supplied from the outside to the magnetron 2, the fan motor 3, and the other load unit 4 under the control of the control unit 7 to operate the microwave oven. have.

상기 마그네트론(2)은 상기 전원부(1)로부터 고압을 인가받아 마이크로파를 발생시키도록 되어 있고, 이 마이크로파가 조리실내의 음식물에 가해져서 음식물을 가열조리한다.The magnetron 2 is applied with a high pressure from the power supply unit 1 to generate microwaves, and the microwaves are applied to food in the cooking chamber to heat food.

상기 팬모터(3)는 상기 마그네트론(2)이 고온으로 상승하는 것을 방지하기 위해 상기 마그네트론(2)으로 송풍하여 마그네트론(2)에서 발생된 열을 식히도록 되어 있다.The fan motor 3 is blown to the magnetron 2 in order to prevent the magnetron 2 from rising to a high temperature to cool the heat generated by the magnetron 2.

그리고, 상기 제어부(7)는 사용자가 상기 입력키이(5)를 통해 입력된 조리선택명령에 따라 전원부(1) 내에 구비되어 있는 각종 릴레이(도시하지 않음) 예를 들어, 메인릴레이, 파워릴레이, 인러쉬릴레이등을 제어하여 마그네트론(2), 팬모터(3), 기타부하부(4)의 구동을 제어함으로써, 전자렌지의 운전을 제어한다.In addition, the controller 7 may include various relays (not shown) provided in the power supply unit 1 according to a cooking selection command inputted through the input key 5, for example, a main relay, a power relay, and the like. The operation of the microwave is controlled by controlling the inrush relay and the like to control the driving of the magnetron 2, the fan motor 3, and the other load portion 4.

또한, 상기 제어부(7)는 마그네트론(2)을 연속적으로 구동시킬 때는 팬모터(3)가 연속적으로 구동되도록 릴레이(8)를 제어하고, 마그네트론(2)을 주기적으로 구동시킬 때는 팬모터(3)가 주기적으로 구동되도록 릴레이(8)를 제어한다.In addition, the controller 7 controls the relay 8 so that the fan motor 3 is continuously driven when the magnetron 2 is continuously driven, and the fan motor 3 is driven when the magnetron 2 is periodically driven. Control the relay 8 to be driven periodically.

즉, 마그네트론(2)이 연속적으로 동작시에는 팬모터(3)를 연속적으로 회전시켜 마그네트론(2)에서 발생된 열을 빠르게 식히고, 마그네트론이 주기적(예를 들어, 10초" 온" 20초 "오프")으로 동작시에는 릴레이(8)를 주기적으로 온/오프시켜 팬모터(3) 역시 주기적으로 동작시킴으로써 팬모터의 회전속도를 낮추는 것이다.That is, when the magnetron 2 is continuously operated, the fan motor 3 is continuously rotated to cool the heat generated by the magnetron 2 quickly, and the magnetron is periodically (for example, 10 seconds "on" 20 seconds " OFF "), the relay 8 is periodically turned on and off, and the fan motor 3 is also periodically operated to lower the rotational speed of the fan motor.

이상에서 살펴본 바와 같이 본 고안에 따르면, 마그네트론의 출력에 따라 팬모터를 연속 또는 주기적으로 동작시킴으로써, 팬모터의 소비전력을 감소시킬 수 있을 뿐만 아니라 팬모터의 수명을 연장시킬 수 있는 효과가 있다.As described above, according to the present invention, by continuously or periodically operating the fan motor according to the output of the magnetron, it is possible to reduce the power consumption of the fan motor as well as to extend the life of the fan motor.
