본 고안 전자레인지에 있어서, 입력전원을 110V/220V 겸용으로 사용할 수 있는 전원겸용회로에 관한 것이다.In the microwave oven of the present invention, it relates to a power supply dual circuit that can be used as an input power supply 110V / 220V.

TM ') and the output control motor (DM') are connected in parallel, and when the power is AC220V, the oven lamp (L 11 ) (L 12 ) is connected in series, and the timer motor (TM ') and the output control motor are connected in series. In case of using a DC (DM ') connected in series or using AC220V, the input voltage is lowered to AC110V by using a low voltage transformer, and an oven lamp, timer motor and output control motor are used to increase the cost of the product. In addition, there have been closures such as wasting unnecessary power.

본 고안은 이와 같은 폐단을 해결하기 위해 오븐램프의 저항값과 동일한 저항값을 갖는 저항을 사용하고 또한, 고압트랜스 1차측의 중간탭에서 전압을 인출하여 하나의 오븐램프 및 타이머모우터만으로도 AC110V/220V 겸용으로 사용할 수 있도록 고안한 것으로서, 이하 첨부도면에 의해 본 고안의 구성 및 작용효과를 설명하면 다음과 같다.The present invention uses a resistor having the same resistance value as that of the oven lamp in order to solve such a closed end, and draws the voltage from the middle tap of the primary side of the high voltage transformer, so that only one oven lamp and the timer motor are AC110V / Designed to be used as a dual 220V, the following describes the configuration and effect of the present invention by the accompanying drawings.

(L) and Timer Motor (TM) are supplied with AC110V voltage respectively to drive lamp (L) and Timer Motor (TM) .When AC 220V is used, common contact (C 1 ) of selection switch (SW 1 ) (SW 2 ) ) (C 2) according to the contact (a 1) (are connected to a 2) the lamp (L) and lamp (R) resistance (R having the same resistance value and the resistance value of the self) is series connected lamps (L ) And the resistor R are supplied with a voltage of 110 VAC, respectively, to drive the lamp L. In addition, the timer motor TM is supplied with an AC 110V voltage drawn from the middle tap of the high voltage transformer HT to drive the timer motor TM.
