본 고안은 일반 가전기기의 110V/220V겸용 전원회로에 있어서, 입력전원이 절환상태와 무관하게 램프 3개를 동시에 점등시킬 수 있도록 한 램프 결선회로에 관한 것이다.The present invention relates to a lamp connection circuit in a 110V / 220V combined power supply circuit of a general household appliance, which allows three lamps to be simultaneously turned on regardless of a switching state.

110V/220V를 겸용하는 국내의 전원조건에서는 전자레인지를 포함하는 일반가전기기도 대체로 110V/220V겸용 전원회로를 구비하고 있다.In domestic power supply conditions that combine 110V / 220V, general household appliances including microwave ovens are usually equipped with 110V / 220V power supply circuits.

그러나, 종래의 110V/220V겸용 전원회로에서는 홀수개, 특히 3개의 램프를 점등시켜야 할 경우 110V 및 220V의 절환전압의 특성상 정격 및 소비전력이 같은 램프를 4개를 사용하여야 하며, 따라서 1개의 램프가 불필요하게 기기에 장착됨에 의해 불필요한 전력소비를 초래하게 되는 단점이 있다.However, in the conventional 110V / 220V dual power supply circuit, when it is necessary to light an odd number of lamps, especially three lamps, four lamps having the same rating and power consumption must be used because of the switching voltage of 110V and 220V. Has an disadvantage that unnecessary power consumption is caused by being unnecessarily mounted in the device.

본 고안의 목적은 이와같은 단점을 해결하기 위한 것으로 110V 또는 220V의 절환전압과 무관하게 정격 및 소비전력이 같은 홀수개, 특히 3개의 램프를 동시에 점등시킬 수 있도록 한 램프결선회로를 제공하기 위한것이다.The purpose of the present invention is to solve such disadvantages, and to provide a lamp connection circuit capable of simultaneously lighting an odd number of lamps having the same rated power consumption, especially three lamps, regardless of a switching voltage of 110V or 220V. .

이와같은 목적을 달성하기 위하여 본 고안은 110V입력시 3개의 램프가 입력전원에 병렬접속되며, 220V입력시에는 하나의 램프가 병렬접속된 2개의 램프에 직렬 접속되도록 3개의 램프가 연동의 전압절환스위치 접점에 결선된다.In order to achieve this purpose, the present invention has three lamps connected in parallel to the input power supply at 110V input, and three lamps are connected in series so that one lamp is connected in series to two lamps connected in parallel at 220V input. It is connected to the switch contact.

이하, 본 고안의 구체적인 구성 및 작용효과를 첨부도면에 의해 상세히 설명한다.Hereinafter, the specific configuration and effect of the present invention will be described in detail by the accompanying drawings.

제1도는 전자레인지에 적용된 본 고안의 램프결선회로를 나타낸 것으로, 연동의 110V/220V 절환스위치(SW1∼SW7)와 제1,2,3램프(L1∼L3)로 구성된 110V/220V겸용 전원회로의 램프결선 회로에 있어서, 일측 입력전원단이 상기 제1램프(L1)의 일단 및 상기 제2절환스위치(SW2)의 공통접점(c2)에 공접되고, 이 제2절환스위치(SW2)의 110V접점(a2)이 상기 제2램프(L2)의 일단 및 상기 제3절환스위치(SW3)의 공통접점(c3)에 공접됨과 동시에, 그 공통접점(c6)이 상기 제1램프(L1)의 타단에 연결되고 그110V접점(a6)이 타측 입력전원단에 연결된 상기 제6절환스위치(SW6)의 220V접점(b6)에 연결되며, 상기 제3절환스위치(SW3)의 110V접점(a3)이 상기 제4절환스위치(SW4)의 110V접점(a4)에 연결되고, 상기 제3절환 스위치(SW3)의 220V접점(b3)이 상기 제4절환 스위치(SW4)의 공통접점(c4) 및 상기 제3램프(L3)의 일단에 연결됨과 동시에. 그 공통접점(c5)이 상기 제2램프(L3)의 타단에 연결되고 그 220V접점(b5)이 상기 제3램프(L3)의 타단 및 타측 입력전원단에 공접된 제5절환스위치(SW5)의 110V접점(a5)에 연결되어 구성된다.1 shows a lamp connection circuit of the present invention applied to a microwave oven, and a 110V / 220V power supply circuit composed of interlocking 110V / 220V switching switches (SW1 to SW7) and first, second and third lamps (L1 to L3). In the ramp connection circuit of FIG. 1, one input power supply terminal is in common with one end of the first lamp L1 and the common contact c2 of the second switching switch SW2, and 110V of the second switching switch SW2. The contact a2 is in contact with one end of the second lamp L2 and the common contact c3 of the third switching switch SW3, and the common contact c6 is connected to the other end of the first lamp L1. The 110V contact a6 is connected to the 220V contact b6 of the sixth switching switch SW6 connected to the other input power terminal, and the 110V contact a3 of the third switching switch SW3 is connected to the 110V contact a6. Connected to the 110V contact a4 of the fourth switch SW4, the 220V contact b3 of the third switch SW3 is the common contact c4 and the third of the fourth switch SW4. Of the lamp (L3) And at the same time it connected to the stage. The fifth switch SW5 of which the common contact c5 is connected to the other end of the second lamp L3 and the 220V contact b5 is in common with the other end of the third lamp L3 and the other input power supply terminal. It is configured to be connected to the 110V contact (a5) of.

미설명 부호중 FS는 휴우즈, TH1,TH2는 온도스위치, SF는 안전스위치, FM은팬모우터, SW은 110V/220V연동 절환스위치, HVT는 고압트랜스, HVD는 고압다이오드, MGT는 마그네트론이다.Unless indicated, FS is fuse, TH1, TH2 is temperature switch, SF is safety switch, FM is fan motor, SW is 110V / 220V interlocking switch, HVT is high voltage transformer, HVD is high voltage diode and MGT is magnetron.

제2도는 전자레인지의 110V/220V겸용 전원회로에 있어서, 종래의 램프결선회로블 도시한 것으로서, 110V또는 220V의 입력전원에 따라 연동의 절환스위치(SW1∼SW7)를 절환시켜줌으로서 고압트랜스(HVT)에 일정고압을 유기시켜 마그네트론(MGT)을 구동시킴과 함께 각 램프(L1∼L4)를 점등시키게 된다.2 shows a conventional lamp wiring circuit in a 110V / 220V combined power supply circuit of a microwave oven, by switching the interlocking switching switches SW1 to SW7 according to an input power supply of 110V or 220V. ) To induce a constant high pressure to drive the magnetron (MGT) and to light each lamp (L1 to L4).

그러나, 전자레인지에 있어서는 홀수개, 특히 3개의 램프만을 점등시킬 필요가 있는데, 110V 및 220V의 전압특성상 절환전압과 무관하게 3개의 램프를 점등시킬 수가 없으므로 4개의 램프(L1∼L4)를 사용하고 있다.However, in the microwave oven, it is necessary to light only an odd number of lamps, especially three lamps. Since three lamps cannot be lit regardless of the switching voltage due to the voltage characteristics of 110V and 220V, four lamps (L1 to L4) are used. have.

즉, 연동의 절환스위치(SW1∼SW7)를 110V로 절환시키면 양측 입력전원단 사이에 각 램프(L1∼L4)가 병렬접속되고, 상기 절환 스위치를 220V로 절환시키면 양측 입력전원단 사이에 램프(L1)(L2) 및 램프(L3)(L4)가 각각 직력접속되도록 결선되어야 하기 때문에 이중 하나의 램프는 불필요하게 장착되어 점등되게게 된다.That is, when the interlocking switch SW1 to SW7 is switched to 110V, each lamp L1 to L4 is connected in parallel between the input power terminals of both sides, and when the switch is switched to 220V, the lamp ( Since the L1) L2 and the lamps L3 and L4 must be connected so as to be directly connected to each other, one of the lamps is unnecessarily mounted and turned on.

제3도(a)는 제1도의 회로에서 절환스위치(SW1∼SW7)가 110V로 절환된 상태를 나타낸 것이다.FIG. 3 (a) shows a state in which the switching switches SW1 to SW7 are switched to 110V in the circuit of FIG.

각 램프(L1∼L3)는 110V의 정격을 가지며, 이 경우 각 램프(L1∼L3)는 110V입력전원단 사이에 병렬접속되도록 결선되어 정상적으로 점등된다.Each lamp L1 to L3 has a rating of 110V. In this case, each lamp L1 to L3 is connected so as to be connected in parallel between the 110V input power supply terminals and is normally turned on.

제3도(b)는 절환스위치(SW1∼SW7)가 220V로 절환된 상태를 나타낸 것으로서, 220V입력전원단 사이에 병렬접속된 램프(L2)(L3)와 램프(L1)가 직렬접속됨으로써 각 램프(L1∼L3)는 정상적으로 점등된다.FIG. 3 (b) shows a state in which the switching switches SW1 to SW7 are switched to 220V, and lamps L2 and L3 and L1 connected in parallel between the 220V input power terminals are connected in series. The lamps L1 to L3 light up normally.

이상과 같이 본 고안은 110V/220V겸용 전원회로에서 절환 전압과 무관하게 홀수개, 특히 3개의 프를 동시에 점등시킬 수 있기 때문에 종래의 램프결선회로에 비하여 추가적인 램프의 설치가 불필요한 전력소비를 방지할수 있는 등의 잇점이 있다.As described above, the present invention can light an odd number, especially three lamps simultaneously, regardless of the switching voltage in the 110V / 220V power supply circuit, thereby preventing unnecessary power consumption compared to the conventional lamp wiring circuit. There is such an advantage.
