본 고안은 전자렌지의 2차 릴레이 소형화 회로에 관한 것으로, 보다 상세하게는 전자렌지의 2차 릴레이를 고압트랜스의 2차측에 설치한 전자렌지의 2차 릴레이 소형화회로에 관한 것이다.The present invention relates to a secondary relay miniaturization circuit of a microwave oven, and more particularly, to a secondary relay miniaturization circuit of a microwave oven in which a secondary relay of a microwave oven is installed on a secondary side of a high voltage transformer.
일반적으로, 전자렌지의 2차 릴레이는 고압트랜스의 1차측에 설치함에 따라 고압트랜스에서 사용되는 대전류를 수용할 수 있는 고전류용 릴레이를 사용하고 있는데 이에 따라 부피가 커지고 생산가가 증가되는 단점이 있었다.In general, as the secondary relay of the microwave oven is installed on the primary side of the high voltage transformer, a high current relay capable of accommodating a large current used in the high voltage transformer has a disadvantage in that the volume is increased and the production cost is increased.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 전자렌지의 2차측 릴레이로서 소용량의 저전류용 릴레이를 사용할 수 있는 전자렌지의 2차측 릴레이 소형화 회로를 제공하는 것을 그 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a microwave secondary relay miniaturization circuit that can use a low-capacity low current relay as a secondary relay of a microwave oven.
상기와 같은 목적을 달성하기 위하여 본 고안은, 램프, 팬모터, 고압트랜스 및 마그네트론으로 이루어진 전자렌지에 있어서, 상기 고압트랜스의 2차측에 소용량의 전자렌지의 2차측 릴레이를 설치한 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that in the microwave oven consisting of a lamp, a fan motor, a high voltage transformer and a magnetron, a secondary relay of a small capacity microwave oven is installed on the secondary side of the high voltage transformer. .
이하, 본 고안의 실시예를 종래의 사용예와 함께 도면에 따라 비교설명한다.Hereinafter, embodiments of the present invention will be described with reference to the drawings along with a conventional use example.
제1도는 종래의 전자렌지 회로도로, 전자렌지의 도어가 닫히면 1차 릴레이(REL1')가 오프되고 1차 전원스위치(SW1')와 2차 전원스위치(SW2')가 온되며 안전스위치(SSW')는 오프되어 사용자의 구동명령에 따라 동작될 수 있는 대기 상태가 된다.1 is a conventional microwave circuit diagram. When the door of the microwave oven is closed, the primary relay REL1 'is turned off, the primary power switch SW1' and the secondary power switch SW2 'are turned on, and the safety switch SSW. ') Is off and becomes a standby state that can be operated according to a user's driving command.
상기와 같은 대기상태에서 전자렌지에 구동명령이 인가되면 오프상태 이던 1차 릴레이(REL1')가 온 되고 다시 2차 릴레이(REL2')도 온되며 이러한 과정에서 고압트랜스(T)에 공급되는 교류전압이 안정화된다.When the driving command is applied to the microwave in the standby state as described above, the primary relay REL1 'that is in the off state is turned on, and the secondary relay REL2' is also turned on, and AC is supplied to the high voltage transformer T in this process. The voltage stabilizes.
상기와 같이 1차 릴레이(REL1')와 2차 릴레이(REL2')외에 2차 릴레이 접점과 직렬로 된 서지전류의 바이패스 저항이 병렬로 연결된 접점을 가진 서지릴레이를 사용한 전자렌지로 공지되어 있다.In addition to the primary relay REL1 'and the secondary relay REL2' as described above, a microwave oven using a surge relay having a contact in which a bypass resistance of a surge current in series with a secondary relay contact is connected in parallel is known. .
상기 과정에서 1차 릴레이(REL1')는 연속적인 온 상태를 유지하는 반면, 2차 릴레이(REL2')는 조리의 선택기능에 따라, 예를 들어 음식물의 해동기능을 수행하는 동안 상기 2차 릴레이의 온 상태를 일시적으로 오프시켰다가 다시 온 시키는 등의 반복적인 스위칭 동작을 할 수 있도록 하여 연속적인 가열상태를 제어하는 동작을 한다.In the process, the primary relay REL1 'maintains a continuous on state, while the secondary relay REL2' is in accordance with a selection function of cooking, for example, during the defrost function of the food. It is possible to control the continuous heating state by enabling the repeated switching operation such as temporarily turning off the on state and turning it on again.
그러나, 상기와 같은 전자렌지의 2차측 릴레이(REL2')는 회로의 구성상 대전류를 수용할 수 있는 고전류용 릴레이를 사용하는 것이 불가피하였다.However, the secondary relay REL2 ′ of the microwave oven as described above has inevitably used a high current relay capable of accommodating a large current.
제2도는 본 고안의 실시예의 회로도로서,2 is a circuit diagram of an embodiment of the present invention,
램프(LAMP), 팬모터(FM), 타이머 모터(TM), 마그네트론(MA)으로 이루어진 전자렌지에 있어서,In the microwave oven consisting of a lamp (LAMP), a fan motor (FM), a timer motor (TM), a magnetron (MA),
고압트랜스(T)의 2차측에 소용량의 2차측 릴레이(REL2)를 설치한 전자렌지의 2차측 릴레이 소형화 회로를 제공한다.Provided is a miniaturization circuit for a secondary side relay of a microwave oven provided with a small capacity secondary side relay REL2 on the secondary side of the high voltage transformer T.
다음에는 상기와 같은 구성으로 이루어진 본 고안의 작용 및 효과를 설명한다.Next will be described the operation and effect of the present invention made of the configuration as described above.
전자렌지의 도어가 닫히면 1차 릴레이(REL1)가 오프되고 1차 전원스위치(SW1)와 2차 전원스위치(SW2)는 온되며 안전스위치(SSW)는 오프되어 사용자의 구동 명령에 따라 동작될 수 있는 대기상태가 된다.When the door of the microwave oven is closed, the primary relay REL1 is turned off, the primary power switch SW1 and the secondary power switch SW2 are turned on, and the safety switch SSW is turned off to operate according to a user's driving command. It is in a waiting state.
상기와 같은 상태에서 전자렌지를 구동하기 위해 구동스위치를 온하면 1차 릴레이(REL1)가 온되고, 2차 릴레이(REL2)도 온되어 전자렌지가 구동하게 되는데, 이때 2차 릴레이(REL2)가 고압트랜스(T)의 2차측에 설치됨에 따라 2차 릴레이(REL2)가 소용량이라도 2차 릴레이(REL2)에는 접지의 전위에 가까운 작은 전류가 흐르므로 하등의 문제가 없다.When the driving switch is turned on to drive the microwave in the above state, the primary relay REL1 is turned on, and the secondary relay REL2 is turned on to drive the microwave oven. In this case, the secondary relay REL2 is turned on. Since the secondary relay REL2 has a small capacity as the secondary relay REL2 is installed on the secondary side of the high voltage transformer T, there is no problem because a small current close to the potential of the ground flows.
상기와 같이 본 고안은 소용량의 2차 릴레이를 고압트랜스의 2차측에 설치함으로써 소용량으로써 주어진 기능을 충분히 수행할 수 있어 시스템의 생산가를 절감하는 효과가 있다.As described above, the present invention can effectively perform a given function as a small capacity by installing a small capacity secondary relay on the secondary side of the high voltage transformer, thereby reducing the production cost of the system.
