본 고안은 냉장고, 쇼케이스등에 장착되어 냉동싸이클을 이루면서 순환되는 냉매를 압축시키기 위한 압축기에 관한 것으로 특히 압축기내의 윤활유가 소정온도 이하로되면 가열시켜 일정한 점도를 유지토록함으로써 압축효을을 더욱 향상시킬 수 있도록 된 압축기의 윤활유 가열장치에 관한 것이다.The present invention relates to a compressor for compressing a refrigerant circulated while forming a refrigeration cycle in a refrigerator, a showcase, and the like. In particular, when the lubricating oil in the compressor is below a predetermined temperature, it is heated to maintain a constant viscosity so that the compression effect can be further improved. It relates to a lubricating oil heating device of a compressor.

일반적으로 압축기는 제1도에 도시한 바와 같이 상, 하부셀(1a)(1b)로 이루어지는 본체(1)내에 회전자(2a)및 고정자(2b)로 이루어지는 전동기부(2)가 설치되고, 상기 회전자(2a)의 중앙에 세위 설치된 주축(3)의 하측에는 실린터(4)내로 공급된 냉매를 압축시키기 위한 피스톤(5)이 결합되며, 그 하측의 하부셀(lb)내에는 상기 주축(3)의 주변부에 윤활을 하기 위한 운활유(6)가 저장되어 있다.Generally, as shown in FIG. 1, the motor part 2 which consists of a rotor 2a and a stator 2b is provided in the main body 1 which consists of upper and lower cells 1a and 1b, A piston 5 for compressing the refrigerant supplied into the cylinder 4 is coupled to the lower side of the main shaft 3 installed at the center of the rotor 2a, and in the lower cell lb at the lower side thereof. Lubricating oil 6 for lubricating the peripheral portion of the main shaft 3 is stored.

이와 같이 구성되는 압축기의 작동은 진동기부(2)에 전원이 인가되면 회전자(2a)가 회전됨과 동시에 주축(3)이 회전하게되고, 상기 주축(3)이 회전함에 따라 그 하측에 결합된 피스톤(5)이 실린더(4)내에서 슬라이드하면서 흡입관(7)을 통하여 유입된 냉매가스를 압축시켜 본체(1)의 일측에 형성된 토출관(8)을 통하여 토출시키게 된다.In the operation of the compressor configured as described above, when power is applied to the vibrator unit 2, the rotor 2a rotates and the main shaft 3 rotates at the same time. As the main shaft 3 rotates, The piston 5 slides in the cylinder 4 and compresses the refrigerant gas introduced through the suction pipe 7 to discharge it through the discharge pipe 8 formed on one side of the main body 1.

그런데, 상기 주축(3)이 회전할때는 그 내측에 형성된 급유공(3a)내로 윤활유(6)가 흡입되어 상기 주축(3)을 지지하는 마찰면으로 공급함으로써 상기 주축(3)이 마찰열에 의해 과열되는 것을 방지하고, 작동시 발생되는 진동, 소음등을 저하시키도록 하게 된다.By the way, when the spindle 3 rotates, the lubricating oil 6 is sucked into the oil supply hole 3a formed therein and supplied to the friction surface supporting the spindle 3 so that the spindle 3 is overheated by frictional heat. To reduce the vibration and noise generated during operation.

그러나, 종래의 압축기는 윤활유의 점도가 온도에 따라 변하게 되어 특히 동절기에 기동시에는 윤활유의 점도가 높게됨으로써 주축이 회전이 원활하지 않게됨은 물론 작동시 심한 진동 및 소음을 발생시키고 압축효율이 현저히 저하되며 수명을 단축시킨다고 하는 문제점이 있다.However, in the conventional compressor, the viscosity of the lubricating oil is changed according to the temperature, and especially when starting in winter, the viscosity of the lubricating oil is high, and thus the main shaft is not rotated smoothly. And there is a problem that shortens the life.

본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 이루어진 것으로서, 본 고안의 목적은 윤활유의 점도에 점도에 영향을 미치는 온도를 감지하여 감지된 온도가 소정온도 이하로 되면 히이터 수단의 작동에 따라 윤활유가 가열되어 항상 낮은 점도가 유지되도록 함으로써 작동시 발생되는 진동 및 소음을 최소화하고 압축효율을 더욱 향상시킬 수 있으며 수명이 더욱 연장된 압축기를 얻을 수 있는 압축기의 윤활유 가열장치를 제공하는데 있다.The present invention is made to solve the problems of the prior art as described above, the object of the present invention is to detect the temperature affecting the viscosity on the viscosity of the lubricating oil and to operate the heater means when the detected temperature is below a predetermined temperature Accordingly, the lubricating oil is heated to maintain a low viscosity at all times, thereby minimizing vibration and noise generated during operation, further improving the compression efficiency, and providing a lubricating oil heating device of a compressor that can obtain a compressor having a longer life.

이와 같은 목적을 실현하기 위하여 이루어진 본 고안에 따른 압축기의 윤활유 가열장치는 본체의 일측벽에 고정설치되는 하우징내에 삽입설치된 형상기억 합금과 상기 형상기억 합금에 탄발설치되고 타측에 스프링을 개재시켜 이동가능케되는 작동봉과, 상기 하우징의 외측에 결합된 단자 케이스내에 고정설치되는 고정단자 및 이 고정단자와 대향하여 탄발설치되는 가변단자와, 상기 고정 가변단자의 접속에 따라 전원이 인가되어 발열하는 히이터 수단을 갖추어서 항상 급유가 원활히 되는 저점도를 유지함으로써 진동 및 소음의 발생을 최소화하고 압축 효율을 증대시키며 수명을 더욱 연장시킬 수 있게 된다.The lubricating oil heating device of the compressor according to the present invention made to achieve the above object is elastically installed in the shape memory alloy and the shape memory alloy installed in a housing fixedly installed on one side wall of the main body, and is movable through a spring on the other side. A working rod to be fixed, a fixed terminal fixedly installed in a terminal case coupled to an outer side of the housing, a variable terminal elastically installed to face the fixed terminal, and heater means for generating heat by applying power according to the connection of the fixed variable terminal. By maintaining a low viscosity to ensure smooth lubrication at all times, it is possible to minimize the generation of vibration and noise, increase the compression efficiency and further extend the life.

이하에 본 고안의 바람직한 실시예를 첨부된 도면 제2도 내지 제4도에 따라서 더욱 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to FIGS. 2 to 4.

도면 제2도는 본 고안에 따른 압축기의 가열장치를 나타내는 횡단면도이고, 제3도는 본 고안의 요부를 나타내는 종단면도이며, 제4도는 본 고안의 작동상태를 나타내는 종단면도로서, 도면에서 부호(10)은 압축기 본체를 나타내고 있다.Figure 2 is a cross-sectional view showing a heating device of the compressor according to the present invention, Figure 3 is a longitudinal cross-sectional view showing the main part of the present invention, Figure 4 is a longitudinal cross-sectional view showing the operating state of the present invention, the reference numeral 10 in the figure Represents the compressor main body.

상기 압축기 본체(10)의 내측에는 전원(11)이 인가됨에 따라 발열하여 윤활유(6)의 온도를 상승시켜 점도가 낮아지도록하는 히이터 수단(12)이 설치되어 있고, 그 일측벽에는 상기 윤활유(6)의 온도변화에 따라 전원을 인가시키기 위한 온도감지수단(13)이 부착되어 있다.Heater means 12 is installed inside the compressor main body 10 so as to generate heat as the power source 11 is applied to increase the temperature of the lubricating oil 6, so that the viscosity is lowered. Temperature sensing means 13 for applying power in accordance with the temperature change of 6) is attached.

상기 온도감지수단(13)은 제3도의 도시와 같이 상기 본체(10)의 일측벽에는 내측에 중공부(14a)가 형성된 하우징(14)이 삽입되어 용접수단등에 의해 고정설치되고, 그 내측에는 코일형상으로 권선된 형상기억합금(15)이 삽입 설치되며, 상기 형상기억합금(15)의 선단에는 일측에 스프링(16)을 삽입설치한 작동봉(17)이 탄발설치되고, 상기 하우징(14)의 외측에는 단자 게이스(18)가 나사결합되어 있다.As shown in FIG. 3, the temperature sensing means 13 has a housing 14 having a hollow portion 14a formed therein in one side wall of the main body 10, and is fixedly fixed by welding means. The shape memory alloy 15 wound in a coil shape is inserted and installed, and an operating rod 17 having a spring 16 inserted therein is installed at one end of the shape memory alloy 15, and the housing 14 is installed. The terminal case 18 is screwed on the outer side.

그리고, 상기 단자케이스(18)내에는 일측에 고정단자(19a)가 고정설치되고, 그 대향측에는 상기 작동봉(I7)의 선단부(17a)가 접촉된 가변단자(19b)가 탄발설치되며, 상기 고정단자(19a) 및 가변단자(19b)는 상기 전원(11)가 접속되어 있다.In addition, a fixed terminal 19a is fixedly installed at one side in the terminal case 18, and a variable terminal 19b in which the tip 17a of the operating rod I7 is in contact with the opposite side is elastically installed. The power supply 11 is connected to the fixed terminal 19a and the variable terminal 19b.

여기에서 상기 형상기억 합금(15)은 윤활유(6)의 온도가 소정온도 이하로 되면 압축되어 상기 작동봉(17)이 스프링(16)의 탄발력에 의해 본체(10)측으로 이동됨으로써, 상기 고정 및 가변단자(19a),(l9b)가 접속되어 상기 히이터수단(12)에 전원이 인가됨에 따라 윤활유(6)를 가열시켜 점도가 낮아지도륵 하게되는 것으로 니켈,티탄 합금 또는 구리, 아연, 알루미늄합금등으로 이루어져 소성온도 이하에서는 압축되어 그 형상이 변하게 되는 것이다.Here, the shape memory alloy 15 is compressed when the temperature of the lubricating oil 6 is lower than a predetermined temperature, and the working rod 17 is moved to the main body 10 side by the elastic force of the spring 16, thereby fixing the above. And the variable terminals 19a and l9b are connected to heat the lubricating oil 6 as the power is applied to the heater means 12, thereby lowering the viscosity of nickel, titanium alloys or copper, zinc, aluminum. It is made of an alloy or the like and is compressed below the firing temperature to change its shape.

이와 같이 구성되는 본 고안에 따른 압축기의 윤활유 가열장치는 본체(10)내에 저장된 윤활유(6)의 온도가 저온으로 되어 점도가 높을때에는 상기 윤활유(6)와 접촉되어 있는 하우징(l4)내에 삽입된 형상기억합금(15)이 그 온도를 감지하여 제4도의 도시와 같이 압축됨으로써, 상기 형상기억합금(15)에 접촉된 작동봉(17)이 스프링(16)의 탄발력에 의해 본체(10)측으로 이동됨과 동시에 상기 작동봉(17)의 선단부 (17a)에 접촉된 가변단자(19b)가 이와 대향설치된 고정단자(19a)와 접촉되어진다.The lubricating oil heating device of the compressor according to the present invention configured as described above is inserted into the housing l4 in contact with the lubricating oil 6 when the temperature of the lubricating oil 6 stored in the main body 10 becomes low and the viscosity is high. When the shape memory alloy 15 senses the temperature and is compressed as shown in FIG. 4, the operating rod 17 in contact with the shape memory alloy 15 is driven by the spring force of the spring 16. The variable terminal 19b which is moved to the side and is in contact with the tip portion 17a of the operating rod 17 is in contact with the fixed terminal 19a which is installed opposite thereto.

즉, 상기 형상기억합금(15)에 의해 탄발된 작동봉(17)이 윤활유(6)의 온도에 의해 형상이 변형되어 압축되면, 상기 작동봉(17)의 선단부(17a)에 의해 상기 고정단자(19a)와 일정거리를 유지하고 있던 가변단자(19b)가 자체의 탄발력에 의해 이동되어 상기 고정단자(19a)와 접촉됨으로써 히이터수단(12)에 전원(11)을 인가시키게 된다.That is, when the shape of the operating rod 17 elasticized by the shape memory alloy 15 is deformed and compressed by the temperature of the lubricating oil 6, the fixed terminal by the front end portion 17a of the operating rod 17 The variable terminal 19b, which has been kept at a constant distance from 19a, is moved by its elastic force and is brought into contact with the fixed terminal 19a to apply the power source 11 to the heater means 12.

상기 히이터수단(12)에 전원이 인가됨에 따라 열이 발생되면 윤활유(6)는 가열이 되어 온도가 상승됨과 동시에 점도가 낮아지게 되어 원활한 윤활유(6)의 공급이 가능케 되고, 이에따라 동절기의 기동시에도 윤활유의 공급이 원활하게 되어 작동에 따른 진동 및 소음의 발생을 최소화함과 동시에 압축효율이 향상되고, 더욱 압축기의 수명의 연장시킬 수 있는 것이다.When heat is generated as power is applied to the heater means 12, the lubricating oil 6 is heated to increase its temperature and at the same time the viscosity is lowered, so that smooth supply of the lubricating oil 6 is possible. In addition, smooth supply of lubricating oil minimizes the occurrence of vibration and noise according to the operation and at the same time improves the compression efficiency, and further extends the life of the compressor.

한편, 상기 히이터 수단(12)의 작동에 따라 윤활유(6)가 가열되어 온도 및 점도가 증가되며 다시 상기 형상기억합금(15)의 형상은 변화되어 팽참됨으로써 상기 작동봉(17)을 이동시켜 고정 및 가변단자(19a),(19b)를 이격시킴과 동시에 상기 히이터 수단(12)에 인가되던 전원을 차단시키게 된다.On the other hand, according to the operation of the heater means 12, the lubricating oil 6 is heated to increase the temperature and viscosity, and again, the shape of the shape memory alloy 15 is changed and bulged so that the operating rod 17 is moved and fixed. And the variable terminals 19a and 19b are separated from each other, and at the same time, the power applied to the heater means 12 is cut off.

이와 같이 본 고안에 따른 압축기의 윤활유 가열장치에 의하면 윤활유의 온도에 따라 형상기억합금의 형상이 변화되면서 히이터 수단에 인가되는 전원을 온, 오프시킴에 따라 상기 윤활유가 항상 공급이 용이하게 되는 점도를 유지토록 함으로써 작동시 발생되는 진동 및 소음을 최소화 할 수 있고, 냉매의 압축효율을 더욱 증대시킬수 있을 뿐만 아나라 압축기의 수명을 더욱 연장시킬 수 있는 이점을 갖는다.As described above, according to the lubricating oil heating device of the compressor according to the present invention, the shape of the shape memory alloy is changed according to the temperature of the lubricating oil, thereby turning on and off the power applied to the heater means a viscosity at which the lubricating oil is always easily supplied. By maintaining it, the vibration and noise generated during operation can be minimized, and the compression efficiency of the refrigerant can be further increased, and the life of the compressor can be further extended.
