Description
본 발명은 자외선 램프와 송풍용 팬을 이용하여 식기류 등을 살균 소독하는 자외선 살균기의 전원 공급기술에 관한 것으로, 특히 자외선 램프나 송풍용 팬이 단독으로 구동되는 것을 방지하고, 하나의 안정기 회로를 겸용하는데 적당하도록한 자외선 살균기의 전원 공급회로에 관한 것이다.The present invention relates to a power supply technology of an ultraviolet sterilizer for sterilizing dishes and the like by using an ultraviolet lamp and a blower fan, and particularly, prevents the ultraviolet lamp and the blower fan from being driven alone, and uses a single ballast circuit. The present invention relates to a power supply circuit of an ultraviolet sterilizer suitable for
일반적으로, 자외선 살균기는 자외선을 조사하는 자외선 램프와, 살균된 공기를 순환시키기 위한 송풍용 팬을 이용하여 식기류나 기타 물품 등을 살균 소독하도록 되어 있다.In general, an ultraviolet sterilizer is used to sterilize dishes and other items by using an ultraviolet lamp for irradiating ultraviolet rays and a blowing fan for circulating the sterilized air.
그런데, 종래 기술에 의한 자외선 살균기에 있어서는 자외선을 조사하는 자외선 램프에 전원을 안정적으로 공급하기 위한 안정기 회로가 구비되어 있고, 이와는 별도로 또 다른 전원공급 장치를 이용하여 송풍용 팬에 전원을 공급하게 되어 있었다. 즉, 서로 독립적으로 구동되는 두 개의 전원공급회로를 이용하여 자외선 램프와 송풍용 팬에 각각의 전원을 공급하게 되어 있었다.However, in the ultraviolet sterilizer according to the prior art, a ballast circuit for stably supplying power to an ultraviolet lamp for irradiating ultraviolet rays is provided, and separately, another power supply device is used to supply power to the blower fan. there was. That is, two power supply circuits driven independently of each other were used to supply power to the ultraviolet lamp and the fan for blowing.
이와 같이 종래기술에 의한 자외선 살균기의 전원공급 장치에 있어서는 서로 독립적으로 구동되는 두 개의 전원공급회로를 이용하여 자외선 램프와 송풍용 팬에 각각 전원을 공급하게 되어 있으므로, 단선이나 고장 등으로 인하여 자외선 램프가 소등되어 자외선 살균기능을 발휘할 수 없는 상태에서도 불필요하게 송풍용 팬이 구동되거나, 반대로 송풍팬이 구동되지 않는 상태에서 자외선 램프만 점등되는 경우가 종종 발생되어 전력이 낭비되는 결함이 있고, 더욱이 불필요한 구동으로 인하여 제품의 수명이 단축되는 문제점이 있었다.As described above, in the power supply device of the ultraviolet sterilizer according to the prior art, power is supplied to the ultraviolet lamp and the blower fan by using two power supply circuits driven independently of each other. Is blown out unnecessarily to operate the ultraviolet fan even when the UV sterilization function can not be performed, or conversely, only the ultraviolet lamp is turned on while the blower is not driven. There was a problem that the life of the product is shortened due to the drive.
따라서, 본 발명의 목적은 하나의 전원 공급회로를 이용하여 자외선 램프와 송풍용 팬에 전원을 공급하고, 그 램프나 팬에 이상이 발생되어 어느 하나가 구동되지 않을 때 다른 하나도 자동적으로 구동 정지상태가 되게 하는 전원공급회로를 제공함에 있다.Accordingly, an object of the present invention is to supply power to the ultraviolet lamp and the fan for blowing by using one power supply circuit, and when the lamp or fan is abnormal and one is not driven, the other is automatically stopped. It is to provide a power supply circuit to be.

도 1은 본 발명의 목적을 달성하기 위한 자외선 살균기의 전원 공급회로의일실시 예시도로서 이에 도시한 바와 같이, 입력되는 교류전원을 전파 정류하고 평활하여 직류전원을 출력하는 정류부(1)와; 상기 정류부(1)로부터 직류전원을 공급받아 두 개의 발진기가 반주씩 교번되게 구동되면서 LC공진회로(3)에 소정 주파수의 교류전원을 출력하는 발진부(2)와; 상기 LC공진회로(3)의 2차권선에 유도되는 교류전압을 정류하여 송풍용 팬(FAN)의 구동전원으로 출력하는 팬구동부(4)와; 상기 LC공진회로(3)를 통해 공급되는 전원을 이용하여 자외선 램프(5)를 점등시키는 램프 구동부(6)로 구성한 것으로, 이와 같이 구성한 본 발명의 작용을 상세히 설명하면 다음과 같다.1 is an exemplary embodiment of a power supply circuit of an ultraviolet sterilizer for achieving the object of the present invention, as shown therein, a rectifier 1 for full-wave rectifying and smoothing the input AC power to output a DC power; An oscillator (2) receiving DC power from the rectifier (1) and outputting an AC power of a predetermined frequency to the LC resonance circuit (3) while two oscillators are alternately driven by accompaniment; A fan driver (4) for rectifying the AC voltage induced in the secondary winding of the LC resonant circuit (3) and outputting it to a driving power supply of a fan for blowing; It is composed of a lamp driver 6 for lighting the ultraviolet lamp 5 by using the power supplied through the LC resonant circuit (3), the operation of the present invention configured as described in detail as follows.
전원입력단자(BK,WH)를 통해 입력되는 상용의 교류전원이 라인필터(L11,L12)를 통해 전자파나 잡음성분이 제거된 후 브리지다이오드(BD1)에 의해 전파정류된다. 상기 전파정류된 전압이 평활용 콘덴서(C2)에 의해 평활되고, 다이오드(D5-D7) 및 콘덴서(C4)로 이루어진 리플제거회로를 통해 리플성분이 완전히 제거된다. 따라서, 정류부(1)에서 안정된 직류전압이 출력된다.The commercial AC power input through the power input terminals BK and WH is rectified by the bridge diode BD1 after electromagnetic waves or noise components are removed through the line filters L11 and L12. The full-wave rectified voltage is smoothed by the smoothing capacitor C2, and the ripple component is completely removed through the ripple removing circuit composed of the diodes D5-D7 and the capacitor C4. Therefore, stable DC voltage is output from the rectifier 1.
발진부(2)는 상기 정류부(1)로부터 직류전압을 공급받아 자려발진하여 소정 주파수의 교류전원을 발생한다. 즉, 제1발진기(2A)의 트랜지스터(Q1)와 제2발진기(2B)의 트랜지스터(Q2)가 반 주기씩 교번되게 온되면서 1차코일(L21),(L22)의 전압이 2차코일(L23)로 유도된다.The oscillator 2 receives the DC voltage from the rectifier 1 and oscillates to generate AC power having a predetermined frequency. That is, while the transistors Q1 of the first oscillator 2A and the transistors Q2 of the second oscillator 2B are alternately turned on by half periods, the voltages of the primary coils L21 and L22 become secondary coils ( L23).
상기 발진부(2)에서 출력되는 전압이 LC공진회로(3)를 통해 자외선 램프(5)에 공급되는데, 초기 상태에서는 콘덴서(C9,C10) 및 다이오드(D12,D13)로 이루어진 스타트 회로에 의해 그 자외선 램프(5)가 점등되고, 이후에는 콘덴서(C8) 및저항(R7)에 의해 안정화된 구동전압을 공급받게 된다.The voltage output from the oscillator 2 is supplied to the ultraviolet lamp 5 through the LC resonant circuit 3, and in the initial state by the start circuit composed of the capacitors C9 and C10 and the diodes D12 and D13. The ultraviolet lamp 5 is turned on, and then the driving voltage stabilized by the capacitor C8 and the resistor R7 is supplied.
상기와 같은 경로를 통해 자외선 램프(5)가 점등된 상태에서, 상기 LC공진회로(3)의 2차코일(L32)에 유기되는 전압이 다이오드(D11)에 의해 정류되고 콘덴서(C7)에 의해 리플성분이 제거된 다음 송풍용 팬(FAN)에 공급되어 그가 소정의 속도로 회전된다.In the state where the ultraviolet lamp 5 is turned on through the path as described above, the voltage induced in the secondary coil L32 of the LC resonance circuit 3 is rectified by the diode D11 and is caused by the capacitor C7. The ripple component is removed and then supplied to a blowing fan (FAN) which is rotated at a predetermined speed.
그런데, 상기와 같은 경로를 통해 자외선 램프(5)와 송풍용 팬(FAN)에 구동전압이 공급되므로 단선이나 고장에 의해 상기 자외선 램프(5)가 소등되는 경우, 상기 LC공진회로(3)의 출력단이 플로팅 상태가 된다. 이에 따라 상기 LC공진회로(3)의 출력전압이 차단되어 즉, 팬구동부(4)의 입력전압이 차단되어 상기 송풍용 팬(FAN)의 구동이 자동으로 정지된다.However, since the driving voltage is supplied to the ultraviolet lamp 5 and the blowing fan FAN through the path as described above, when the ultraviolet lamp 5 is turned off due to disconnection or failure, the LC resonance circuit 3 The output stage is in a floating state. Accordingly, the output voltage of the LC resonant circuit 3 is cut off, that is, the input voltage of the fan driving part 4 is cut off, and the driving of the blowing fan FAN is automatically stopped.
이상에서 상세히 설명한 바와 같이 본 발명은, 발진회로의 출력전압을 LC공진회로를 통해 자외선 램프측으로 공급하고 다른 한편으로는 그 LC공진회로의 2차코일에 유도되는 전압을 팬구동부에 공급하게 되므로, 단선이나 고장 등의 이유로 인하여 자외선 램프가 소등되는 경우 자동적으로 팬의 구동이 정지되어 팬이 불필요하게 단독적으로 구동되는 일이 발생되지 않고 이로 인하여 전력 낭비가 방지되고 제품의 수명이 연장되는 효과가 기대된다.As described in detail above, the present invention supplies the output voltage of the oscillation circuit to the ultraviolet lamp side through the LC resonant circuit, and on the other hand, supplies the voltage induced in the secondary coil of the LC resonant circuit to the fan driver. If the UV lamp is turned off due to disconnection or failure, the fan will stop automatically and the fan will not be driven alone unnecessarily. This will prevent power waste and extend the life of the product. do.
