Abstract

PURPOSE: A rotary compressor for an air conditioner is provided to improve durability and efficiency and to easily apply a substituted refrigerant by inserting a cylindrical pin between a vane and a roller to minimize frictional loss. CONSTITUTION: Refrigerant gas is flowed into a compressor through a suction aperture by the drive of an air conditioner by being filtered in an accumulator. When a rotational shaft(21) of the compressor is rotated, a roller(11) fixed in the rotational shaft is rotated. A vane(12) contacted with the roller is reciprocated by the roller in a compressing chamber(14) in a cylinder(10). Thus, the refrigerant gas is compressed by separating a high compressed portion and a low pressurize portion. Herein, a pin(12a) formed at the end of the vane is assembled in a cylindrical groove(11a) on one side of the roller. Then, the pin is rotated for the roller to revolve.

Description

에어컨의 로터리 압축기(A rotary compressor of air conditioner)A rotary compressor of air conditioner

본 발명은 에어컨에 설치되는 압축기에 관한 것으로서, 구체적으로는 로터리 압축기의 실린더부에서 편심되어 회전되는 로울러에 원통형의 홈을 형성하고 이 홈에 접촉되어 로울러와 반대방향으로 회전되는 핀이 삽입되어 형성되는 베인을 구성하여 로울러와 베인 사이의 내구성을 증가하며 효율을 향상하도록 하는 로터리 압축기에 관한 것이다.The present invention relates to a compressor installed in an air conditioner. Specifically, a cylindrical groove is formed in a roller that is eccentrically rotated in a cylinder part of a rotary compressor, and the pin is contacted with the groove to be rotated in a direction opposite to the roller. It relates to a rotary compressor to configure the vanes to increase the durability and increase the durability between the roller and the vanes.

일반적으로 에어컨은 공기를 순환시키면서 냉동싸이클과 연동되어 실내공기를 냉각시켜 냉방을 하는 것으로서 그 구성은 크게 실내기와 실외기로 나누어지고 이 실내기와 실외기가 한 몸체에 설치되어 구성된 것을 일체형 에어컨이라 하며, 각각 별도로 분리되어 설치되는 것을 분리형 에어컨이라 한다.In general, the air conditioner cools indoor air by interlocking with a refrigeration cycle while circulating air, and the air conditioner is divided into an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are installed in one body. Separately installed is called a separate type air conditioner.

상기와 같이 실내기와 실외기로 구성되는 에어컨의 실내기에는 증발기와 시로콘 팬의 상호 작용에 의해 실내공기를 흡입하고 토출하는 역할을 하는 것이고, 실외기에는 압축기와 응축기 및 냉각팬이 형성되어 실외공기를 흡입하고 토출하는 역할을 한다.As described above, the indoor unit of the air conditioner composed of the indoor unit and the outdoor unit serves to suck and discharge the indoor air by the interaction between the evaporator and the sirocon fan, and the outdoor unit is configured to suck the outdoor air by forming a compressor, a condenser, and a cooling fan. And discharge.

상기와 같은 에어컨은 냉동 싸이클의 원리 즉, 증발기 내에서의 흡열작용에 의해 기화된 냉매가스는 압축기 내에서 기계적인 작동에 의해 고온고압의 가스가 되고 이 가스는 응축기를 거쳐 응축되면서 액체가 되고 다시 팽창밸브에서 증발기로 보내면 재차 증발되는 흡열작용을 반복하면서 실내공기를 저온으로 낮추는 것이다.In the air conditioner as described above, the refrigerant gas vaporized by the endothermic action in the evaporator becomes a gas of high temperature and high pressure by mechanical operation in the compressor, and this gas becomes a liquid as it condenses through the condenser. When the expansion valve is sent to the evaporator, the endothermic action of evaporation is repeated, and the indoor air is lowered to a low temperature.

상기에서 압축기는 피스톤의 왕복운동으로 냉매기체를 압축한 다음 이를 응축시키고 팽창시켜 냉매가 기화됨으로서 주위의 열을 빼앗는 원리를 이용하여 외부에서 흡입된 공기의 온도를 낮추는 것이다.The compressor compresses the refrigerant gas by reciprocating the piston, and then condenses and expands the refrigerant gas to lower the temperature of the air sucked from the outside by using the principle of taking away the heat of the surroundings by vaporizing the refrigerant.

상기와 같이 냉매가스를 고온,고압으로 압축하는 종래의 에어컨에 설치되는 로터리 압축기의 구성은 도 3에 도시된 바와 같이 몸체(30)의 외측으로 증발기에서 증발된 저온·저압의 냉매가스를 흡입하는 흡입관(41)이 어큐뮤레이터(40)와 같이 설치되고 몸체(30)의 내부에는 상부로 내주연에 편심부(22)를 갖는 회전축(21)과 회전자(23)가 내장된 전동기(20)가 설치되며 하부에는 상측으로 모터베어링(24)이, 하측으로 펌프베어링(25)이 설치되어 내주연에 상기 회전축(21)의 편심부(22)와 로울러(11)가 일체로 설치되는 실린더(10)가 형성된다.The configuration of the rotary compressor installed in a conventional air conditioner for compressing the refrigerant gas at a high temperature and high pressure as described above is to suck the refrigerant gas of low temperature and low pressure evaporated from the evaporator to the outside of the body 30 as shown in FIG. The suction tube 41 is installed together with the accumulator 40, and the inside of the body 30 has a rotary shaft 21 and a rotor 23 having an eccentric portion 22 at an inner circumference thereof. ) Is installed in the lower part, the motor bearing 24 is installed on the upper side, the pump bearing 25 is installed on the lower side, the eccentric portion 22 and the roller 11 of the rotary shaft 21 is integrally installed on the inner circumference. (10) is formed.

상기 몸체(50)는 외부단자(31)와 토출관(32)이 형성된 상부커버(33)와 체결공이 형성된 베이스 플레이트가 설치되는 하부커버(34) 및 몸통(35)으로 구분된다.The body 50 is divided into an upper cover 33 on which an external terminal 31 and a discharge tube 32 are formed, and a lower cover 34 and a body 35 on which a base plate on which a fastening hole is formed is installed.

상기 실린더(10)에는 일측으로 어큐뮤레이터(40)를 거친 냉매가스가 흡입되게 흡입구(42)가 형성되고 타측에는 압축된 냉매가스가 토출밸브(도시 없음)에 의해 개폐되어 토출되도록 토출구(도시 없음)가 형성되며 상기 로울러(11)의 작동시 고압측과 저압측을 나누기 위해 베인(도시 없음)이 설치되는 구성으로 되어 있다.The cylinder 10 has a suction port 42 formed at one side to suck the refrigerant gas through the accumulator 40 to one side, and the discharge port (not shown) at the other side so that the compressed refrigerant gas is opened and discharged by a discharge valve (not shown). None) is formed and a vane (not shown) is installed to divide the high pressure side and the low pressure side when the roller 11 is operated.

이와 같이 구성되어진 압축기의 작동은 증발기에서 증발된 저온·저압의 냉매가스가 흡입관(41)을 통해 냉매가스에 함유된 액상의 냉매와 이물질등을 제거하기 위해 설치된 어큐뮤레이터(40)를 거쳐 흡입구(42)를 통하여 실린더(10) 내로 흡입된다.The operation of the compressor configured as described above is carried out through the intake port 40 of the refrigerant gas evaporated from the evaporator through the accumulator 40 installed to remove the liquid refrigerant and foreign matter contained in the refrigerant gas through the suction pipe 41. It is sucked into the cylinder 10 through 42.

이렇게 흡입된 냉매가스는 전동기(20)의 모터 회전력이 회전축(21)에 직접 전달되어 회전하면서 흡입구(42)를 통해 유입된 냉매가스를 편심부(22)와 로울러(11)의 유막접촉에 의한 회전으로 인해 압축실(14)에서 압축되어지고, 이 압축된 냉매가스는 토출밸브의 작용에 의해 토출구로 토출하게 되는 것이다.The refrigerant gas sucked in this way is the motor rotational force of the motor 20 is transmitted directly to the rotating shaft 21 to rotate the refrigerant gas introduced through the suction port 42 by the oil film contact between the eccentric portion 22 and the roller 11. It is compressed in the compression chamber 14 due to rotation, and the compressed refrigerant gas is discharged to the discharge port by the action of the discharge valve.

상기 토출구를 거쳐 토출되는 고온·고압의 냉매가스는 몸통(35)내를 거쳐 상부커버(33)에 형성된 토출관(32)을 통해 응축기로 토출되는 것이다.The high temperature and high pressure refrigerant gas discharged through the discharge port is discharged to the condenser through the discharge pipe 32 formed in the upper cover 33 through the body 35.

도 4는 도 3에서 실린더부의 평 단면도로서, 실린더(10)의 내부로 편심된 회전축(21)에 장착되어 회전되는 로울러(11)와 이 로울러(11)에 접촉되며 스프링(12b)을 장착한 베인(12)에 의하여 압축실(14)을 고압측과 저압측으로 나누어진다.FIG. 4 is a cross sectional view of the cylinder portion in FIG. 3, in which the roller 11 is mounted on the rotating shaft 21 eccentrically into the cylinder 10 and is in contact with the roller 11 and the spring 12b is mounted. The vane 12 divides the compression chamber 14 into a high pressure side and a low pressure side.

즉, 종래의 로터리 압축기는 베인(12) 배면의 고압에 의해 로울러(11)와 베인(12) 사이의 부하가 큰데 비해 윤활이 원활치 못한 장소여서 경계윤활 과부하시는 금속간 접촉까지 되므로 내구성 및 이 부위의 누설로 인해 효율이 저하되는 문제점이 있었다.That is, the conventional rotary compressor has a large load between the roller 11 and the vane 12 due to the high pressure of the back of the vane 12, but it is a place where lubrication is not smooth. There was a problem that the efficiency is lowered due to leakage.

특히 대체냉매 사용시에는 기존 냉매에 비해 냉매 자체의 윤활성이 없으므로 더욱 문제가 커지게 되는 것이다.In particular, when using a replacement refrigerant, the problem is further increased because there is no lubricity of the refrigerant itself compared to the existing refrigerant.

본 발명은 상기와 같은 종래의 로터리 압축기에서의 문제점을 개선하기 위한 것으로서, 로터리 압축기의 베인과 로울러사이는 미끄럼운동과 구름운동이 복합되어 있어 로울러가 공전만 하고 자전하지 못하도록 하여 미끄럼운동을 없애주고 베인과 로울러 사이에 원통형 핀을 삽입하여 마찰손실을 최소화하여 내구성향상과 효율도모 및 환경보호 관련 대체냉매 적용을 용이화 할 수 있는 에어컨의 로터리 압축기를 제공하는 것에 그 목적이 있다.The present invention is to improve the problems of the conventional rotary compressor as described above, between the vane and the roller of the rotary compressor is a sliding and rolling motion is complex, so that the roller is not rotating and do not rotate to eliminate the sliding motion It is an object of the present invention to provide a rotary compressor of an air conditioner that inserts a cylindrical pin between vanes and rollers to minimize frictional losses, thereby facilitating the application of alternative refrigerants related to improved durability, efficiency, and environmental protection.

상기와 같은 목적을 달성하기 위하여 본 발명은 증발기로부터의 저온·저압의 냉매가스를 흡입관을 통하여 어큐뮤레이터를 거쳐 흡입구로 흡입되어 고온·고압으로 압축된 다음 토출관으로 토출되어 응축기로 보내지는 에어컨의 로터리 압축기에 있어서, 실린더의 내부로 편심된 회전축에 장착되어 회전되는 로울러의 일측으로 원통형의 홈을 형성하며, 이 로울러의 홈에 접촉되어 로울러와 반대방향으로 회전되는 핀이 삽입되며 베인홀에 장착되어 스프링에 의하여 왕복운동하며 압축실을 고압부와 저압부로 분리하는 베인으로 구성되는 것을 특징으로 하는 것이다.In order to achieve the above object, the present invention provides a low-temperature, low-pressure refrigerant gas from the evaporator is sucked into the inlet through the accumulator through the suction pipe, compressed to high temperature and high pressure, then discharged to the discharge pipe is sent to the condenser In the rotary compressor of the cylinder, a cylindrical groove is formed on one side of the roller which is mounted on the rotating shaft eccentrically into the cylinder, and the pin is contacted with the groove of the roller and rotated in the opposite direction to the roller is inserted into the vane hole.
