본 고안은 전자렌지에 관한 것으로, 더 상세하게는 회로기판에 장착되어 전기소자로 공급되는 전압을 감압하는 저압트랜스를 회로기판에 견실하게 고정하는 전자렌지에 관한 것이다.The present invention relates to a microwave oven, and more particularly, to a microwave oven for firmly fixing a low-voltage transformer for reducing the voltage supplied to an electric element mounted on a circuit board to the circuit board.
전자렌지는 고주파를 조사하여 피조리물을 조리하는 것으로, 이러한 전자렌지에는 작동 및 조리방법 등을 제어하기 위한 회로기판이 장착된다. 회로기판에는 명령의 입력과 제어를 위한 다수의 전기소자와 전기소자로 공급되는 전압을 소자에 알맞게 감압하는 저압트랜스가 탑재된다. 도1은 저압트랜스의 장착을 보인 도면이다. 이에 도시한 바와 같이, 저압트랜스(1)가 탑재된 회로기판(2)이 제어판넬(3)의 후면에 형성된 보스(4)에 나사(5)결합을 통하여 장착된다. 저압트랜스(1)는 회로기판(2)에 나사(6)결합되어 탑재된다.The microwave oven cooks a cooked object by irradiating a high frequency wave, and the microwave oven is equipped with a circuit board for controlling an operation and a cooking method. The circuit board is equipped with a plurality of electric elements for inputting and controlling commands and a low voltage transformer for reducing the voltage supplied to the electric elements appropriately for the elements. 1 is a view showing the mounting of the low-voltage transformer. As shown in the drawing, the circuit board 2 on which the low voltage transformer 1 is mounted is mounted to the boss 4 formed on the rear surface of the control panel 3 through the screw 5 coupling.

There was a fear that the circuit board, which consists of plates, was weak. As a result, the connection of the low voltage transformer was broken, and there was a fear that the microwave oven would not operate.
따라서 본 고안은 상기한 문제를 해결하기 위한 것으로, 본 고안의 목적은 저압트랜스를 회로기판이 장착되는 보스에 직접 체결하여 저압트랜스을 견실하게 장착함으로써 저압트랜스의 접속이 파괴되는 것을 방지할 수 있는 전자렌지를 제공하는 것이다.Therefore, the present invention is to solve the above problems, an object of the present invention is to fasten the low-voltage transformer directly to the boss on which the circuit board is mounted to securely mount the low-voltage transformer electronics that can prevent the connection of the low-voltage transformer is destroyed To provide a stove.

도2는 본 고안이 적용된 전자렌지의 내부구성을 보인 도면이다. 이에 도시한 바와 같이, 전자렌지는 피조리물이 수납되는 조리실(20)과 조리실(20)로 고주파를 조사하여 피조리물이 조리되도록 하는 마그네트론(31)을 포함한다. 이를 상세하게 설명하면, 본체케이스(10)의 내부에는 조리실(20)과 전장품실(30)이 서로 구획되어 형성된다. 조리실(20)의 전면은 개구되어 조리실(20)의 입구를 형성한다. 전장품실(30)에는 조리실(20)로 고주파를 조사하는 마그네트론(31)과 마그네트론(31)으로 고압을 공급하기 위한 고압트랜스(32)와 고압캐패시터(33)가 함께 수용설치된다. 그리고 전장품실(30)의 전면에는 전자렌지의 작동을 제어하기 위한 제어박스(40)가 설치된다. 제어박스(40)는 본체케이스(10)에 형성된 설치공에 결합되는 제어판넬(41)과 제어판넬(41)의 전면에 결합설치되는 전면판넬(42)과 제어판넬(41)의 후면에 결합설치되는 회로기판(43)을 포함한다. 이때 회로기판(43)은 제어판넬(41)의 후면에 나사(47)결합되는데, 여기에는 제어와 명령의 입력을 위한 다수개의 전기소자(46)가 탑재된다.2 is a view showing the internal configuration of a microwave oven to which the present invention is applied. As shown in the drawing, the microwave oven includes a cooking chamber 20 in which a cooking object is stored and a magnetron 31 for irradiating high frequency to the cooking chamber 20 to cook the cooking object. In detail, the cooking chamber 20 and the electrical equipment compartment 30 are partitioned from each other in the body case 10. The front surface of the cooking chamber 20 is opened to form an entrance of the cooking chamber 20. In the electrical equipment room 30, a magnetron 31 for irradiating high frequency to the cooking chamber 20 and a high voltage transformer 32 and a high voltage capacitor 33 for supplying a high pressure to the magnetron 31 are housed together. And a control box 40 for controlling the operation of the microwave oven is installed on the front of the electrical equipment room 30. The control box 40 is coupled to the rear panel of the control panel panel 41 and the control panel panel 41 coupled to the front of the control panel panel 41 and the control panel 41 coupled to the installation hole formed in the main body case 10 And a circuit board 43 to be installed.

That is, the boss 45 protruding backward from the rear of the control panel 41 is integrally formed, and the screw 47 is fastened to the boss 45 and the circuit board 43 so that the circuit board 43 is connected to the control panel. 41 is mounted. In addition, the circuit board 43 is equipped with a low voltage transformer 44 for appropriately reducing the voltage supplied to the plurality of electric elements 46. Since the low voltage transformer 44 is composed of a plurality of iron plates, the weight is considerable compared to the volume. Has In order to reliably mount the heavy low pressure transformer 44, a holder 50 surrounding the low pressure transformer 44 is installed, and both ends of the holder 50 are extended to correspond to the boss 45 so as to be connected by a screw 47. The low pressure transformer 44 is coupled to the boss 45 integrally with the substrate 43 so that the force by the load of the low pressure transformer 44 having a weight per upper end is applied directly to the sturdy boss 45 through the screw 47. The circuit board 43 is prevented from being damaged by the load.
이와 같이 구성된 본 고안에 따른 전자렌지는 조리실(20)에 수납된 피조리물은 마그네트론(31)에서 조사되는 고주파에 의하여 조리된다.The microwave oven according to the present invention configured as described above is cooked by the high frequency irradiated from the magnetron 31 to be housed in the cooking chamber 20.
이상에서 상세하게 설명한 바와 같이, 본 고안에 따른 전자렌지는 상당한 무게를 가지는 저압트랜스를 보스에 직접 체결함으로써 하중의 집중에 의한 회로기판의 파손을 방지할 수 있다. 이로써 저압트랜스를 견실하게 고정할 수 있어 저압트랜스의 유동에 의한 단선 등을 방지할 수 있다.As described in detail above, the microwave oven according to the present invention can directly prevent the breakage of the circuit board due to the concentration of load by fastening a low-voltage transformer having a considerable weight directly to the boss. As a result, the low pressure transformer can be firmly fixed, and disconnection due to the flow of the low pressure transformer can be prevented.
