본 발명은 과열감지기능을 가지는 스크롤압축기에 관한 것으로, 더욱 상세하게는 스크롤압축기의 압축실 내부 이상으로 인한 고온 토출시, 신속한 경고 또는 운전정지가 가능하도록 한 것이다.The present invention relates to a scroll compressor having an overheat detection function, and more particularly, to enable a quick warning or stop of operation during high temperature discharge due to an abnormality inside the compression chamber of the scroll compressor.

일반적으로, 스크롤압축기는 유체를 압축하는 장치로서, 예를들어 공기를 압축하는 스크롤압축기인 경우, 주요 구성요소로서 고정스크롤부재와 선회스크롤부재 가 갖추어져 있다. 이 한쌍의 스크롤부재는 돌출,형성된 팁들이 서로 접촉하고 있는데, 압축과정중 구동기구의 이상으로 고정 및 선회스크롤 팁간 접촉 또는 팁실의 이상으로 인해 과압축이 발생하여 압축실 내부의 과도한 온도상승이 발생하게 된다.Generally, a scroll compressor is a device for compressing a fluid, for example, a scroll compressor for compressing air, and is provided with a fixed scroll member and a swing scroll member as main components. The pair of scroll members are in contact with the protruding and formed tips. During compression, overcompression occurs due to contact between the fixed and swinging scroll tips or abnormality of the tip chamber, or excessive temperature rise inside the compression chamber. Done.

이러한 현상을 방지하기 위해, 종래에는 도 1에 도시된 바와 같이, 고정스크롤부재(10)의 저면 일측에 과도한 온도상승을 방지하기 위한 감지수단으로서, 서어미스터(thermistor)(20)가 갖추어져 있다. In order to prevent such a phenomenon, conventionally, as shown in FIG. 1, a thermistor 20 is provided as a sensing means for preventing excessive temperature rise on one side of the bottom surface of the fixed scroll member 10.

그런데, 고정 및 선회스크롤부재의 랩간의 접촉이 발생하여 압축실 내부 온도가 급격히 상승하는 경우, 상기 서어미스터(20)가 고정스크롤부재(10)의 바디측 하부 일측에 갖추어져 있기때문에, 과열온도를 감지하는데에는 일정한 시간이 경과되어야 경고 또는 정지를 위한 온도에 도달하게 된다. 즉, 사이드에 치우쳐 설치되어 있기때문에 위와 같이 지연시간이 발생하는 것이다.  However, in the case where the contact between the laps of the fixed and swinging scroll members occurs and the compression chamber internal temperature rises sharply, the thermistor 20 is provided on one side of the lower side of the body side of the fixed scroll member 10 so that the overheating temperature is increased. A certain amount of time must pass for detection to reach a temperature for warning or shutdown. That is, the delay time occurs because it is installed on the side.

이런 경우에는 스크롤압축기의 스크롤 랩 부분이 크게 손상되어서 사용 불능상태에 도달할 수 있는 등의 문제점이 있었다. In this case, there is a problem that the scroll wrap portion of the scroll compressor is largely damaged to reach an unusable state.

이에 본 발명은 상기와 같은 종래의 제반 문제점을 해결하기 위해 발명된 것으로서, 스크롤압축기의 압축실 내부 이상으로 인한 과도한 온도상승을 바로 감지하여 기기의 손상을 미연에 방지할 수 있도록 한 과열온도 감지기능을 가지는 스크롤압축기를 제공함에 그 목적이 있다. Accordingly, the present invention has been invented to solve the above-mentioned conventional problems, an overheat temperature detection function that can immediately detect excessive temperature rise due to an internal abnormality of the compression chamber of the scroll compressor to prevent damage to the device. The purpose is to provide a scroll compressor having a.

상기와 같은 목적을 달성하기 위한 본 발명은 고정스크롤부재와, 이 고정스크롤부재와 결합되고 선회운동을 하면서 유체를 압축하는 선회스크롤부재로 이루어진 스크롤압축기에 있어서, 상기 고정스크롤부재의 상부의 토출파이프의 일측면에 과열감지를 위한 감지수단을 장착한 것을 기술적 특징으로 한다.The present invention for achieving the above object is a scroll compressor consisting of a fixed scroll member, and a rotating scroll member coupled to the fixed scroll member and compressing the fluid while the pivoting movement, the discharge pipe of the upper portion of the fixed scroll member It is characterized in that the technical means equipped with a sensing means for detecting overheating on one side of.

상기 감지수단은 서어미스터로 이루어져 있다. The sensing means consists of a thermistor.

이하 본 발명의 바람직한 실시예를 첨부된 예시도면에 의거 상세히 설명한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 고정스크롤부재에 장착된 감지수단을 나타낸 개략적인 단면도이다. 도면에 도시된 바와 같이, 고정스크롤부재(10)는 종래와 동일한 구조를 가지고 있다. 즉, 고정스크롤부재(10)는 랩(11)이 형성되고, 도면상 상부에는 중앙에서 압축된 고온/고압의 압축공기를 배출하는 토출파이프(30)가 갖추어져 있다. 이 토출파이프(30)의 일측면에 과열온도를 감지할 수 있는 감지수단인 서어미스터(40)를 구비한 구조이다. Figure 2 is a schematic cross-sectional view showing a sensing means mounted to a fixed scroll member according to the present invention. As shown in the figure, the fixed scroll member 10 has the same structure as the prior art. That is, the fixed scroll member 10 has a wrap 11 is formed, the upper portion is provided with a discharge pipe 30 for discharging the compressed air of the high temperature / high pressure compressed in the center. On one side of the discharge pipe 30 is a structure provided with a thermistor 40, which is a sensing means for sensing the overheat temperature.

이러한 구성을 가지는 본 발명은 고정스크롤부재(10)와 결합되는 선회스크롤부재(미도시)가 선회운동을 하면, 고정스크롤부재(10)와 선회스크롤부재 사이의 밀폐면적이 변화하게 되어서 외곽에서 중심쪽으로 압력이 증가되고, 고정스크롤부재의 중심부에 형성된 토출파이프(30)를 통해서 압축공기가 배출된다. According to the present invention having such a configuration, when the swinging scroll member (not shown) coupled to the fixed scroll member 10 makes a pivoting movement, the sealed area between the fixed scroll member 10 and the swinging scroll member is changed to a center at the outside. The pressure is increased toward the side, and compressed air is discharged through the discharge pipe 30 formed at the center of the fixed scroll member.

이때, 압축과정에서 압축실 내부에는 온도가 상승하게되고, 과도한 온도상승이 발생하는지의 여부를 상기 서어미스터(40)를 통해 바로 확인가능하다. 이러므로써, 과열되는경우, 스크롤압축기의 운전을 정지시키도록 하는 것이다. At this time, the temperature rises inside the compression chamber during the compression process, and it is immediately possible to check whether the excessive temperature rise occurs through the thermistor 40. Thus, when overheating, the operation of the scroll compressor is to be stopped.

본 발명에 따른 서어미스터(40)에 의해 감지된 온도는 통상의 제어부를 거쳐서 스크롤압축기의 운전상태를 제어할 수 있도록 구성되어 있는바, 측정 하고자 하는 부분의 온도를 감지할 수 있는데, 서어미스터(40)에서 감지한 온도 차를 저항 변화로 나타내어 기판과 연결된 마이컴에서 A/D 변환 과정을 통하여 전압으로 읽어들여 제어를 하도록 되어있다. The temperature sensed by the thermistor 40 according to the present invention is configured to control the operation state of the scroll compressor through a conventional control unit, and can sense the temperature of the part to be measured. The temperature difference detected in 40) is expressed as a change in resistance, and the microcomputer connected to the board reads the voltage through the A / D conversion process and controls it.

이와 같이 본 발명은 고정스크롤부재의 토출파이프 일측에 온도감지수단인 서어미스터를 부착하여 공기가 압축되는 과정에서 압축실 내부의 온도가 상승하는 것을 바로 감지하여 기기의 손상을 미연에 방지할 수 있도록 하는 효과가 있다. As described above, the present invention attaches a thermistor, which is a temperature sensing means, to one side of the discharge pipe of the fixed scroll member so that the internal temperature of the compression chamber is increased in the process of compressing air, thereby preventing damage to the device. It is effective.

본 발명은 편의상 첨부된 예시도면에 의거 본 발명의 일 실시예를 설명하였지만, 이에 국한되지 않고 본 발명의 기술적 사상의 범주내에서 여러가지 변형 및 수정이 가능함은 자명한 사실이다.Although the present invention has been described with reference to one embodiment of the present invention based on the accompanying drawings for convenience, it is obvious that various modifications and changes are possible within the scope of the technical idea of the present invention.
