본 고안의 압축기의 과부하 보호장치 개선구조, 더욱 상세하게는 압축기에 극전환 모터를 사용할 경우 이를 제어할 수 있는 압축기의 과부하 보호장치 개선구조에 관한 것이다.Improved structure of the overload protection device of the compressor of the present invention, and more particularly, to improve the structure of the overload protection device of the compressor that can control when using a pole switching motor in the compressor.
일반적으로, 공기조화기에 설치된 압축기는 증발기에서 유입되는 저온, 저압의 기체 냉매를 흡입하여, 고온, 고압의 기체 냉매로 압축시키는 작용을 한다.In general, the compressor installed in the air conditioner sucks the low-temperature, low-pressure gas refrigerant flowing from the evaporator, and serves to compress the high-temperature, high-pressure gas refrigerant.
이러한 압축기는 냉매를 고압으로 압축하기 위해 비교적 높은 회적속도와 토오크를 요구하게 되므로 이 과정에서 많은 열이 발생되었고, 특히 초기 운전시 또는 재기동시에는 과전류가 유기되면서 과부하와 과열이 빈번히 발생하였다.Since the compressor requires a relatively high rotational speed and torque to compress the refrigerant to a high pressure, a lot of heat is generated in this process. In particular, overload and overheating frequently occur while overcurrent is induced during initial operation or restart.
상기 과열 현상은 기기의 내부에 설치된 고정자를 손상시켜 압축성능을 저해하는 주요 요인이 되므로 과부하와 과열을 미연에 방지하기 위해 압축기의 동작시 집중적인 과열이 발생되는 상부에 과열상태를 감지한 후 그 동작을 제어하여 기기를 보호하는 과부하 보호장치를 설치하였다.The overheating phenomenon is a main factor that impairs the compression performance by damaging the stator installed inside the device, so that after detecting the overheating state in the upper part where intensive overheating occurs during the operation of the compressor to prevent overload and overheating. An overload protection device is installed to protect the equipment by controlling its operation.
제1도는 종래의 압축기를 나타낸 측면도이고, 제2도는 종래의 과부하 보호장치를 나타낸 확대 단면도로서, 압축기 몸체(1)의 상부를 밀폐시키는 상부캡(2)에 설정온도 이상의 과열발생시 정지신호를 보내는 과부하 보호장치(3)가 착설된다.FIG. 1 is a side view showing a conventional compressor, and FIG. 2 is an enlarged cross-sectional view showing a conventional overload protection device, which sends a stop signal when an overheat occurs above a set temperature to an upper cap 2 which seals an upper portion of the compressor body 1. An overload protection device 3 is installed.
상기 과부하 보호장치(3)는 접속부(9)(9')가 일측단에 형성된 접점단자(8)(8')와, 접점단자(8)(8')가 끼워져 고정된 하우징(4)과, 상기 접점단자(8)(8')에 각각 접촉되는 접점부(5')(5'')가 형성된 디스크(5)와, 상기 하우징(4)에 상기 디스크(5)를 고정시키는 고정볼트(6)와 고정너트(7)로 구성되어 있었다.The overload protection device 3 includes a contact terminal 8, 8 ′ having a connection portion 9, 9 ′ formed at one end thereof, and a housing 4 in which contact terminals 8, 8 ′ are fitted and fixed. A disk 5 having contact portions 5 'and 5 " in contact with the contact terminals 8 and 8', and a fixing bolt for fixing the disk 5 to the housing 4; (6) and fixing nuts (7).
따라서, 압축기의 상부캡(3)으로 부터 전도되는 온도를 감지하여 동작되는 디스크(5)의 접점부(5')(5'')가 정상동작시 접점단자(8)(8')에 접촉되고 과열시나 과부하시에는 디스크(5)가 팽창되어 접점단자(8)(8')와 떨어져 전원공급을 차단함에 따라 보호하게 된다.Accordingly, the contact portions 5 'and 5' 'of the disk 5, which operate by sensing the temperature conducted from the upper cap 3 of the compressor, come into contact with the contact terminals 8 and 8' during normal operation. In the case of overheating or overloading, the disk 5 expands and is separated from the contact terminals 8 and 8 'to protect the power supply.
그러나, 상기 과부하장치에 디스크가 하나만 설치되어 있어서, 다수개의 접속단자가 필요한 극전환 모터가 장착된 압축기에서는 과부하 보호장치가 제 기능을 발휘하지 못하는 문제점이 있었다.However, since only one disk is installed in the overload device, there is a problem in that the overload protection device does not function properly in a compressor equipped with a pole switching motor requiring a plurality of connection terminals.
본 고안은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로, 극전환 모터를 사용하는 압축기에서도 사용할 수 있도록 과부하장치의 구조를 개선하여 압축기내에 설치된 모터를 보호하고 제품의 신뢰도를 향상시킬 수 있는 압축기의 과부하 보호 장치 개선구조를 제공함을 목적으로 한다.The present invention has been made to solve the above-mentioned conventional problems, by improving the structure of the overload device for use in a compressor using a pole switching motor to protect the motor installed in the compressor and improve the reliability of the product An object of the present invention is to provide an overload protection device for the compressor.
상기와 같은 목적을 달성하기 위하여 본 고안은, 과부하보호장치의 내부에 바이메탈로 된 디스크를 두개소 설치하여 극전환 모터가 사용되는 압축기에서도 제 기능을 발휘할 수 있고, 아울러 부품을 단순화하여 제조단가를 낮출 수 있도록 구성된 것을 특징으로 한다.In order to achieve the above object, the present invention, by installing two bimetal disks inside the overload protection device can perform a function even in a compressor using a pole switching motor, and at the same time simplify the parts to reduce the manufacturing cost Characterized in that configured to be lowered.
이하, 본 고안의 실시예의 압축기의 과부하보호장치 개선구조를 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter, the overload protection device improved structure of the compressor of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

') Is formed to include contact terminals 8, 8', 20 and 20 'fixed to the housing 4, respectively.
상기 접점단자(8)(8')(20)(20')는 ㄴ자형으로 형성되어 있다.The contact terminals 8, 8 ', 20 and 20' are formed in a N-shape.
상기와 같이 구성된 본 고안의 과부하 보호장치는 압축기의 구동에 의해 발생되는 열이 상부캡(3)을 통해 과부하를 감지하는 바이메탈로 된 디스크(5)(30)에 전도되어 감지된 온도가 정상범위 이내일 경우 디스크(5)(30)의 접점부(5')(5'')(30')(30'')가 접점단자(8)(8')(20)(20')와 떨어지면서 전원을 차단하여 압축기를 보호하는 통상적인 작용을 한다.In the overload protection device of the present invention configured as described above, the heat generated by driving the compressor is conducted to the bimetal disks 5 and 30 that detect the overload through the upper cap 3, and the detected temperature is in a normal range. If within the contact points 5 ', 5', 30 'and 30' of the disks 5 and 30, they are separated from the contact terminals 8, 8 ', 20 and 20'. It protects the compressor by shutting off the power supply.
