Description
본 발명은 전자레인지에 관한 것으로, 더욱 상세하게는 조리실을 조명하는 램프의 밝기를 다단계로 제어할 수 있는 램프밝기 조정장치를 구비한 전자레인지와 그 제어방법에 관한 것이다.The present invention relates to a microwave oven, and more particularly, to a microwave oven having a lamp brightness adjusting device capable of controlling the brightness of the lamp for illuminating the cooking chamber in multiple stages and a control method thereof.
일반적으로 전자렌지(Micro wave oven)는 열전도 및 열복사 등을 이용한 외부 가열 방식의 조리가구와는 달리 초고주파에 의하여 조리를 하는 장치이다. 이러한 전자렌지는 마그네트론이라는 초고주파 발진관에 고압전기를 가하여 2,450㎒의 초고주파를 발생시킨다. 마그네트론에서 발생된 2,450㎒의 초고주파는 1초에 24억 5천만번이나 전계의 방향이 바뀌는데, 이 초고주파를 식품에 가하게 되면 식품을 구성하고 있는 분자들은 1초에 24억 5천만번이나 회전하게 되고 많은 마찰열이 발생하게 되며 이 열에 의하여 식품이 조리된다.In general, a microwave oven is a device for cooking by ultra-high frequency unlike an external heating type cooking furniture using heat conduction and heat radiation. The microwave oven generates a high frequency of 2450 MHz by applying a high voltage to a microwave oscillation tube called magnetron. The 2,450MHz high frequency generated from the magnetron changes the direction of the electric field by 2.45 billion times a second. When this high frequency is applied to the food, the molecules that make up the food rotate 2.45 million times a second and a lot of frictional heat. Is generated and food is cooked by this heat.
상기한 종래의 전자레인지는 조리가 시작되면 조리실에 설치된 램프를 온시켜 조리완료시 까지 동일한 밝기로 조리실을 조명하게 된다. 그러나 조리 초기에는 전류소모가 큰 만큼 램프의 밝기를 정격으로 유지하게 되면 램프에서 소비되는 전류만큼 마그네트론의 출력이 저하될 우려가 있어 조리의 완성도가 떨어지는 문제점이 있었다. 또한 다른 전장품으로 공급될 전류를 램프에서 소비하므로 오작동의 우려가 있었다.In the conventional microwave oven, when cooking starts, the lamp installed in the cooking chamber is turned on to illuminate the cooking chamber with the same brightness until the cooking is completed. However, in the early stages of cooking, when the brightness of the lamp is maintained at the rated value as the current consumption is large, there is a concern that the output of the magnetron may be reduced as much as the current consumed by the lamp. In addition, there is a risk of malfunction because the lamp consumes the current to be supplied to other electrical appliances.
본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 조리실을 조명하는 램프의 밝기를 다단계로 제어할 수 있는 램프밝기 조정장치를 구비한 전자레인지와 그 제어방법을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a microwave oven having a lamp brightness adjusting device capable of controlling the brightness of a lamp for illuminating the cooking chamber in multiple stages, and a control method thereof.

Connected.
도 2는 본 발명에 따른 전자레인지의 램프구동부를 설명하기 위한 상세 블록도이다.2 is a detailed block diagram illustrating a lamp driving unit of the microwave oven according to the present invention.
도 2를 참조하면, 본 발명에 따른 램프(71)와 전원(AC)사이에는 램프구동부(70)가 마련되는데, 램프구동부(70)는 램프(71)와 전원(AC) 사이에 병렬로 접속되는 제 1 릴레이(RY1) 및 제 2 릴레이(RY2)를 구비하고, 상기 제 1 릴레이(RY1) 및 제 2 릴레이(RY2)를 구동하는 릴레이구동부(70a)를 포함하며, 상기 제 1릴레이(RY1)에는 전원(AC)을 반파정류하기 위한 다이오드(D)가 직렬로 접속된다.2, a lamp driver 70 is provided between the lamp 71 and the power source AC according to the present invention, and the lamp driver 70 is connected in parallel between the lamp 71 and the power source AC. And a relay driver 70a for driving the first relay RY1 and the second relay RY2, the first relay RY1 being provided with a first relay RY1 and a second relay RY2. ) Is connected in series with a diode D for half-wave rectifying the power supply AC.
이에 따라 상기 제 1 릴레이(RY1)가 온되면 전원(AC)은 다이오드(D)에 의해 반파정류되어 전원(AC) 전압의 절반정도의 전압이 램프(71)에 인가된다. 또한 상기제 2 릴레이(RY2)가 온되면 전원(AC)의 전체 전압이 램프(71)에 인가된다. 즉, 상기 제 1 릴레이(RY1) 및 제 2 릴레이(RY2)의 스위칭을 제어함으로써 램프(71)에 인가되는 전압을 다단계로 제어할 수 있어 램프(71)의 밝기를 다단계로 제어할 수 있다.Accordingly, when the first relay RY1 is turned on, the power source AC is half-wave rectified by the diode D, and a voltage about half of the voltage of the power source AC is applied to the lamp 71. In addition, when the second relay RY2 is turned on, the total voltage of the power source AC is applied to the lamp 71. That is, by controlling the switching of the first relay RY1 and the second relay RY2, the voltage applied to the lamp 71 can be controlled in multiple stages, so that the brightness of the lamp 71 can be controlled in multiple stages.
이하에서는 본 발명에 따른 램프밝기 조정방법에 대하여 설명하도록 한다.Hereinafter, a lamp brightness adjusting method according to the present invention will be described.
도 3은 본 발명에 따른 전자레인지의 제어방법을 설명하기 위한 제어 흐름도이다.3 is a control flowchart illustrating a control method of the microwave oven according to the present invention.
도 3을 참조하면, 사용자는 입력부(10)를 통하여 조리설정을 한다(S10). 그리고 제어부(30)는 입력부(10)를 통하여 조리시작명령이 입력되는지를 판단한다(S20).Referring to FIG. 3, the user sets cooking through the input unit 10 (S10). In addition, the controller 30 determines whether a cooking start command is input through the input unit 10 (S20).
단계(S20)에서 입력부(10)를 통하여 조리시작명령이 입력된다고 판단되면 제어부(30)는 마그네트론구동부(41)를 제어하여 마그네트론(42)을 구동함으로써 고주파를 발생(S30)시키며, 팬구동부(51)를 제어하여 냉각팬(52)을 구동한다.If it is determined in step S20 that the cooking start command is input through the input unit 10, the controller 30 controls the magnetron driver 41 to drive the magnetron 42 to generate high frequency (S30), and the fan driver ( 51 is driven to drive the cooling fan 52.
그리고 제어부(30)는 모터구동부(61)를 제어하여 트레이모터(62)를 구동시킨다. 트레이모터(62)가 구동되면 트레이모터(62)의 회전축에 설치된 조리접시가 회전을 하게 된다(S40).The controller 30 controls the motor driver 61 to drive the tray motor 62. When the tray motor 62 is driven, the cooking plate installed on the rotating shaft of the tray motor 62 rotates (S40).
그리고 제어부(30)는 램프(71)의 밝기가 1단계가 되도록 램프구동부(70)를 제어한다(S50). 램프구동부(70)는 제어부(30)의 제어에 따라 릴레이구동부(71)를 통하여 제 1 릴레이(RY1)를 온시킨다. 이때 제 2 릴레이(RY2)는 오프상태이다.In addition, the controller 30 controls the lamp driver 70 so that the brightness of the lamp 71 becomes one level (S50). The lamp driver 70 turns on the first relay RY1 through the relay driver 71 under the control of the controller 30. At this time, the second relay RY2 is off.
상기 제 1 릴레이(RY1)가 온되면 전원(AC), 제 1 릴레이(RY1), 다이오드(D) 및 램프(71)사이에 폐회로가 형성된다. 이에 따라 전원(AC)은 다이오드(D)에 의해 반파정류되어 원래 전압의 절반 정도의 크기를 가지는 전압이 램프(71)에 인가된다.When the first relay RY1 is turned on, a closed circuit is formed between the power source AC, the first relay RY1, the diode D, and the lamp 71. Accordingly, the power source AC is half-wave rectified by the diode D, and a voltage having a magnitude of about half of the original voltage is applied to the lamp 71.
단계(S50)에서 램프(71)의 밝기를 1단계로 제어한 후, 제어부(30)는 미리 설정된 소정시간이 경과했는지를 판단한다(S60). 상기 소정시간은 약 2분으로써, 조리 진행시 소비전류가 안정되어 잉여전류가 발생되는 미리 설정된 시간이다.After controlling the brightness of the lamp 71 in one step in step S50, the controller 30 determines whether a predetermined time has elapsed (S60). The predetermined time is about 2 minutes, which is a preset time when the consumption current is stabilized and a surplus current is generated during cooking.
단계(S60)에서 상기 소정시간이 경과했다고 판단되면 제어부(30)는램프(71)의 밝기가 상기 1단계 보다는 밝은 2단계가 되도록 램프구동부(70)를 제어한다(S70).If it is determined in step S60 that the predetermined time has elapsed, the controller 30 controls the lamp driving unit 70 so that the brightness of the lamp 71 becomes two levels brighter than the first step (S70).
램프구동부(70)는 램프(71)를 2단계 밝기로 구동할 수 있도록 제어부(30)의 제어에 따라 릴레이구동부(71)를 통하여 제 2 릴레이(RY2)를 온시킨다. 이때 제 1 릴레이(RY1)는 오프상태이다.The lamp driver 70 turns on the second relay RY2 through the relay driver 71 under the control of the controller 30 to drive the lamp 71 at two levels of brightness. At this time, the first relay RY1 is off.
상기 제 2 릴레이(RY2)가 온되면 전원(AC), 제 2 릴레이(RY2), 다이오드(D) 및 램프(71)사이에 폐회로가 형성된다. 이에 따라 전원(AC)은 전체 전압이 램프(71)에 인가된다. 따라서 램프(71)의 밝기는 단계(S50)의 1단계 보다 더 밝게 빛을 발산하게 된다.When the second relay RY2 is turned on, a closed circuit is formed between the power source AC, the second relay RY2, the diode D, and the lamp 71. Accordingly, the power source AC is supplied with the full voltage to the lamp 71. Therefore, the brightness of the lamp 71 emits light brighter than step 1 of step S50.
제어부(30)는 조리시간이 완료되었는지를 판단한다(S80). 단계(S80)에서 조리시간이 완료되었다고 판단되면 제어부(30)는 마그네트론구동부(41)를 제어하여 마그네트론(42)의 구동을 정지시킨다(S90).The controller 30 determines whether the cooking time is completed (S80). When it is determined in step S80 that the cooking time is completed, the controller 30 controls the magnetron driver 41 to stop driving of the magnetron 42 (S90).
그리고 제어부(30)는 모터구동부(61)를 제어하여 트레이모터(62)의 구동을 정지시킨다. 이에 따라 트레이모터(62)의 회전축에 설치된 조리접시의 회전이 정지된다(S100).The controller 30 controls the motor driver 61 to stop driving of the tray motor 62. Accordingly, the rotation of the cooking plate provided on the rotation shaft of the tray motor 62 is stopped (S100).
전술한 바와 같이 본 발명에 따른 램프밝기 조정장치를 구비한 전자레인지와 그 제어방법에 의하면, 전류소모가 큰 조리초기의 램프의 밝기와, 조리가 소정시간 진행 후의 램프의 밝기를 다단계로 제어함으로써, 램프 사용에 의한 조리 초기의 전자레인지 출력저하를 방지하여 조리의 완성도를 높일 수 있다.As described above, according to the microwave oven having the lamp brightness adjusting device according to the present invention and a control method thereof, by controlling the brightness of the lamp of the initial cooking stage with a large current consumption and the brightness of the lamp after the cooking has been progressed for a predetermined time in multiple stages. In addition, it is possible to increase the degree of completion of cooking by preventing the decrease in microwave output at the beginning of cooking due to the use of a lamp.
