본 발명은 레이저 프린터나 복사기 등 화상형성장치에 관한 것으로, 보다 상세하게는 교류 전원을 이용하여 정착기를 가열하는 정착 램프에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a laser printer or a copying machine, and more particularly, to a fixing lamp for heating a fixing unit using an AC power source.

정착기의 기본 구성요소로는 열원을 발생하는 정착 램프 및 정착 램프의 열원을 받아 인쇄 용지 위에 전사된 토너를 고르게 정착시켜 주는 히트 롤러로 구성된다.The basic components of the fixing unit include a fixing lamp that generates a heat source, and a heat roller that receives the heat source of the fixing lamp and evenly fixes the toner transferred onto the printing paper.

종래의 정착 램프는 할로겐 가스로 채워진 유리관 안에 텅스텐 필라멘트가 감겨 있는 구조로 되어 있다. 위치에 따른 온도편차를 줄이기 위해 유리관 안의 위치에 따라 감겨 있는 필라멘트의 정도가 다르고 용량에 따라서도 감겨있는 수 또는 반경이 다르다. The conventional fixing lamp has a structure in which tungsten filaments are wound in a glass tube filled with halogen gas. In order to reduce the temperature deviation according to the position, the degree of filament wound is different according to the position in the glass tube, and the number or radius of the wound depends on the capacity.

한편, 정착 램프를 포함하는 히트 롤러는 롤러의 중앙에 정착 램프가 위치하고 램프의 표면부터 히트 롤러의 내측면까지의 거리가 상당한 거리만큼 이격되어 있다.On the other hand, in the heat roller including the fixing lamp, the fixing lamp is positioned at the center of the roller, and the distance from the surface of the lamp to the inner surface of the heat roller is spaced apart by a considerable distance.

기존의 레이저 프린터용 정착기 회로에서는 입력 전원부의 AC 전원을 인가 받아 정착 램프가 가열되고, 정착 램프의 복사열에 의해 히트 롤러가 가열됨으로써, 정착에 필요한 온도가 발생하게 된다.In a conventional fuser circuit for a laser printer, a fixing lamp is heated by receiving AC power from an input power supply unit, and a heat roller is heated by radiant heat of the fixing lamp, thereby generating a temperature required for fixing.

그런데, 종래 기술에 의하면, 히트 롤러의 내측면과 정착 램프의 표면 사이의 거리가 멀기 때문에, 복사열로 히트 롤러를 가열시키는 과정에서 열 손실이 크다는 문제점이 있다. 또한, 온도편차를 줄이기 위해 국부적으로 텅스텐 필라멘트의 감긴 수를 조정하고 있으나 세밀한 변화가 어렵기 때문에 온도편차 발생이 불가피하여 정착 램프의 수명을 단축시키는 문제점이 있다.However, according to the prior art, since the distance between the inner surface of the heat roller and the surface of the fixing lamp is far, there is a problem that the heat loss is large in the process of heating the heat roller by radiant heat. In addition, although the number of tungsten filaments wound is adjusted locally to reduce the temperature deviation, there is a problem of shortening the lifespan of the fixing lamp due to the inevitable occurrence of temperature deviation.

본 발명이 이루고자 하는 기술적 과제는 정착기의 효율개선 및 소비전력 저감에 유효한 정착 램프를 제공하는데 있다. The technical problem to be achieved by the present invention is to provide a fixing lamp effective for improving the efficiency of the fixing unit and power consumption.

상기의 과제를 이루기 위해, 본 발명에 의한 정착 램프는 전원을 입력받아 열을 발생하는 코일부, 코일부에서 발생하는 열을 손실 없이 반사하는 반사체부 및 코일부 및 반사체부를 내부에 구비하고, 소정 반경을 갖는 유리관부를 포함하고, 코일부가 반사체부에 감겨져 있다. In order to achieve the above object, the fixing lamp according to the present invention is provided with a coil part for generating heat by receiving power, a reflector part for reflecting heat generated by the coil part without loss, and a coil part and a reflector part therein. A glass tube part having a radius is included, and the coil part is wound around the reflector part.

이하, 본 발명에 의한 정착 램프를 첨부된 도면을 참조하여 상세히 설명한 다. Hereinafter, a fixing lamp according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 의한 정착 램프를 설명하기 위한 일 실시예의 도면으로서, 코일부(100), 반사체부(120) 및 유리관부(140)로 구성된다.1 is a view illustrating an embodiment of a fixing lamp according to the present invention, and includes a coil part 100, a reflector part 120, and a glass tube part 140.

코일부(100)는 전원을 입력받아 열을 발생하는 구성요소이다. The coil unit 100 is a component that generates heat by receiving power.

코일부(100)는 반사체부(120)에 감겨져 있다. 이때, 코일부(100)는 반사체부(120)의 위치에 따라 서로 다른 밀도로 감겨져 있다. 유리관부(140)의 위치에 따라 온도편차가 발생하기 때문에 이러한 온도 편차를 줄이기 위해 유리관 안의 위치에 따라 밀도를 달리하여 코일이 감겨져 있다. 코일부(100)는 반사체부(120)에 감겨져 있기 때문에 종래와 달리, 위치에 따른 코일의 밀도 조정이 자유롭다. 따라서, 종래에 비해 유리관 내에서의 위치에 따른 코일의 밀도를 용이하게 조정할 수 있으므로, 유리관 내의 온도 편차를 최소화할 수 있다. The coil part 100 is wound around the reflector part 120. At this time, the coil unit 100 is wound at different densities depending on the position of the reflector unit 120. Since the temperature deviation occurs according to the position of the glass tube 140, the coil is wound by varying the density according to the position in the glass tube to reduce the temperature deviation. Since the coil part 100 is wound around the reflector part 120, the density of the coil is freely adjusted according to the position unlike the conventional art. Therefore, since the density of the coil can be easily adjusted according to the position in the glass tube as compared with the related art, the temperature variation in the glass tube can be minimized.

코일부(100)는 텅스텐 재질의 필라멘트인 것을 특징으로 한다.The coil unit 100 is characterized in that the filament of tungsten material.

반사체부(120)는 코일부(100)에서 발생하는 열을 손실 없이 반사하는 기능을 한다. 이를 위해, 반사체부(120)는 절연 재질의 반사체인 것을 특징으로 한다. 반사체부(120)의 반경은 유리관부(140)의 크기에 맞게 조정할 수 있다. 따라서, 반경이 큰 유리관부(140)가 요구될 때에, 반사체부(120)의 반경을 크게 함으로써, 반경이 큰 유리관부(140)을 구현할 수 있다.The reflector 120 serves to reflect the heat generated from the coil unit 100 without loss. To this end, the reflector portion 120 is characterized in that the reflector of the insulating material. The radius of the reflector portion 120 may be adjusted according to the size of the glass tube portion 140. Therefore, when the glass tube portion 140 having a large radius is required, the glass tube portion 140 having a large radius can be realized by increasing the radius of the reflector portion 120.

유리관부(140)는 코일부(100) 및 반사체부(120)를 내부에 구비하고 있으며, 소정 반경을 갖는다. 여기서, 유리관부(140)의 소정 반경은 히트 롤러(미도시)의 반경에 따라 조정 가능한 것을 특징으로 한다. 즉, 유리관부(140)의 소정 반경은 히트 롤러의 내측면에 근접하는 반경을 갖는 것을 특징으로 한다. 유리관부(140)가 히트 롤러의 내측면에 근접하는 반경을 갖는다면, 정착 램프에서 발생하는 복사열이 인접하는 히트 롤러에 바로 전달되기 때문에 복사열의 낭비를 방지할 수 있다.The glass tube part 140 has the coil part 100 and the reflector part 120 inside, and has a predetermined radius. Here, the predetermined radius of the glass tube 140 is adjustable according to the radius of the heat roller (not shown). That is, the predetermined radius of the glass tube portion 140 is characterized by having a radius close to the inner surface of the heat roller. If the glass tube part 140 has a radius close to the inner surface of the heat roller, the radiant heat generated in the fixing lamp is transferred directly to the adjacent heat rollers, thereby preventing waste of radiant heat.

이러한 본원 발명인 정착 램프는 이해를 돕기 위하여 도면에 도시된 실시예를 참고로 설명되었으나, 이는 예시적인 것에 불과하며, 당해 분야에서 통상적 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호 범위는 첨부된 특허청구범위에 의해 정해져야 할 것이다.Such a fixing lamp of the present invention has been described with reference to the embodiment shown in the drawings for clarity, but this is only an example, and those skilled in the art that various modifications and equivalent other embodiments are possible. I will understand the point. Therefore, the true technical protection scope of the present invention will be defined by the appended claims.

본 발명에 의한 정착 램프는 열원인 정착 램프와 히트 롤러의 거리가 가깝기 때문에 열이 전달되는 시간이 단축되어 정착시간을 줄일 수 있고, 열 복사과정에서 손실되는 열을 최소화함으로써, 열 효율을 개선할 수 있으며, 정착 램프에 구비되는 코일의 온도 편차에 따른 조정을 세밀하게 할 수 있으므로, 정착램프의 수명 저하를 방지하는 효과가 있다.In the fixing lamp according to the present invention, since the distance between the fixing lamp, which is a heat source, and the heat roller is close, the heat transfer time is shortened, thereby reducing the fixing time, and minimizing the heat lost in the heat radiation process, thereby improving thermal efficiency. In addition, since the adjustment according to the temperature deviation of the coil provided in the fixing lamp can be made fine, there is an effect of preventing the deterioration of the life of the fixing lamp.
