본 발명은 압축기의 요동방지장치에 관한 것으로서, 더욱 상세하게는 압축기와 케이싱 사이에 개재되어 압축기의 진동을 효율적으로 방지할 수 있는 요동방지장치에 관한 것이다. The present invention relates to an apparatus for preventing oscillation of a compressor, and more particularly, to an apparatus for preventing oscillation interposed between a compressor and a casing so as to effectively prevent vibration of the compressor.

일반적으로 압축기는 공기조화기나 냉장고 등에서 냉매 사이클을 통해 소정 공간의 공기를 냉각시키는데 사용되는 장치이다. Generally, a compressor is a device used to cool air in a predetermined space through a refrigerant cycle in an air conditioner or a refrigerator.

냉매 사이클을 대략적으로 살펴보면, 가스상의 냉매는 압축기에 의해 고온 고압으로 압축된 후 응축기에서 액화되고, 액화된 냉매는 팽창밸브를 통해 압력이 저하된 후 증발기로 유입되어 주위의 열을 빼앗으면서 증발한다. 그리고, 증발한 냉매는 가스상이 되어 다시 압축기에 흡입된다. 냉방은 증발기에 송풍팬을 설치하여 차가워진 공기를 외부로 송풍함으로써 이루어지고, 이와 같은 사이클이 반복됨으로써 공기의 온도가 점진적으로 떨어지게 된다.In the refrigerant cycle, the gaseous refrigerant is compressed to a high temperature and high pressure by the compressor and then liquefied in the condenser, and the liquefied refrigerant is introduced into the evaporator after the pressure is reduced through the expansion valve and evaporates away from the surrounding heat. . The evaporated refrigerant then becomes gaseous and is again sucked into the compressor. Cooling is achieved by blowing a cold air to the outside by installing a blower in the evaporator, and by repeating such a cycle, the temperature of the air gradually drops.

그런데, 이와 같이 냉매 사이클에 사용되는 압축기는 냉방운전 시 진동에 의해 소음이 크게 발생하게 되는데, 이를 저감시키기 위해서 종래에는 도 1에 도시한 한국실용신안출원 제1992-21131호의 압축기 유동방지장치와 같이, 압축기의 하부에 다수의 고정편을 가지는 브라켓(1)을 부착하고, 이 브라켓(1)의 고정편 하부와 케이싱 사이에 방진고무(3)를 개재시킨 후 볼트(2)와 너트(미도시)로 이들을 체결하여 고정 설치하였다. By the way, the compressor used in the refrigerant cycle is a large noise generated by the vibration during the cooling operation, in order to reduce this, conventionally, as in the compressor flow prevention device of the Korea Utility Model Application No. 1992-21131 shown in FIG. A bracket 1 having a plurality of fixing pieces is attached to the lower part of the compressor, and a bolt 2 and a nut (not shown) are interposed between the lower part of the fixing piece of the bracket 1 and the anti-vibration rubber 3 between the casing. ) And fixed them by tightening them.

그러나, 상기와 같은 종래의 압축기 유동방지장치는 냉방운전 중에 발생하는 진동 및 소음을 저감시키는데는 효과적이나, 제품 운반 중에 발생하는 진동에 대해서는 취약한 점이 있었다. 예컨대, 종래의 압축기 유동방지장치는 압축기 내부에서 발생하는 한계응력을 140MPa로 설정하여 마련되는데, 운반 중에 압축기에 가해지는 응력은 수평진동시 285~333MPa로 상기 설정값을 상회한다. 따라서, 공기 조화기의 실외기에 설치되는 압축기와 같이, 압축기의 유동이 심할 경우에는 요동방지장치가 설치되어 있음에도 불구하고 압축기가 크게 진동하게 되고, 이는 결국 진동에 취약한 압축기의 배관에 응력을 집중시켜 순환하는 냉매를 누출시키는 문제점을 유발하였다. However, the conventional compressor flow preventing device is effective to reduce the vibration and noise generated during the cooling operation, but has a weak point against the vibration generated during product transportation. For example, the conventional compressor flow prevention device is provided by setting the limit stress generated inside the compressor to 140MPa, the stress applied to the compressor during transportation exceeds the set value to 285 ~ 333MPa during horizontal vibration. Therefore, like a compressor installed in an outdoor unit of an air conditioner, when the flow of the compressor is severe, the compressor vibrates greatly despite the vibration prevention device, which eventually concentrates stress on the piping of the compressor which is vulnerable to vibration. It caused a problem of leaking circulating refrigerant.

본 발명은 상술한 종래기술의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 냉방운전 시 뿐만 아니라 제품의 운반과 같은 외부 진동에도 압축기가 요동하는 것을 방지하기 위한 압축기의 요동방지장치를 제공하는 데 있다.

또한, 상기 볼트는 상기 케이싱의 바닥에 용접 결합된다. The bolt is also welded to the bottom of the casing.

이하 본 발명의 바람직한 실시예에 따른 압축기의 요동방지장치를 첨부된 도면을 참조하여 상세히 설명하기로 한다. 여기서, 본 실시예는 공기조화기용 압축기를 일례로 예시하였으나, 본 발명은 이에 한정되지 않고 냉장고와 같이 압축기를 사용하는 다른 전자기기에도 적용될 수 있음은 물론이다.Hereinafter, the shaking device of the compressor according to the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. Here, the present embodiment exemplifies an air conditioner compressor as an example, but the present invention is not limited thereto and may be applied to other electronic devices using a compressor such as a refrigerator.

도 2는 본 발명에 따른 압축기의 요동방지장치가 설치된 공기조화기의 실외기를 개략적으로 도시한 도면이다. 도면을 참조하면, 공기조화기의 실외기는 외형을 형성하는 본체 케이싱(10)에 구획판(11)을 구비하여 내부를 열교환기실(S1)과 압축기실(S2)로 구획하고 있으며, 각 구획실에는 실외기를 구성하는 열교환기(12), 송풍팬(3) 및 압축기(15) 등이 효율적으로 분리 배치되어 있다. 2 is a view schematically showing an outdoor unit of an air conditioner in which a shake prevention device of a compressor according to the present invention is installed. Referring to the drawings, the outdoor unit of the air conditioner is provided with a partition plate 11 in the main body casing 10 forming an outer shape, and partitions the inside into a heat exchanger chamber S1 and a compressor chamber S2. The heat exchanger 12, the blower fan 3, the compressor 15, etc. which comprise an outdoor unit are arrange | positioned efficiently.

즉, 열교환실(S1)에는 후방으로 "ㄱ"자 형태로 절곡된 열교환기(12)가 설치되며, 그 전방에는 열교환기(12)의 열교환이 가능하도록 외부 공기를 강제로 흡입하여 송풍하는 송풍팬(13)이 설치된다. 송풍팬(13)은 지지부재(14)에 의해 본체 케이싱(10)의 바닥판에 고정된다. That is, the heat exchanger 12, which is bent in the shape of "a" in the rear, is installed in the heat exchange chamber S1, and the blower forcibly sucks and blows outside air to allow heat exchange of the heat exchanger 12 in front The fan 13 is installed. The blowing fan 13 is fixed to the bottom plate of the main body casing 10 by the supporting member 14.

또한, 압축기실(S2)에는 냉매를 고온 고압으로 압축하는 압축기(15)가 하부에 설치되며, 그 상부에는 각종 부품이 실장된 회로기판(미도시)이 설치된다. 미설명된 참조부호 16은 냉매가 흐르는 배관이다. In the compressor chamber S2, a compressor 15 for compressing a refrigerant at a high temperature and high pressure is installed at a lower portion thereof, and a circuit board (not shown) on which various components are mounted is installed at the upper portion thereof. Unexplained reference numeral 16 is a pipe through which the refrigerant flows.

도 3은 압축기의 요동방지장치를 도시한 분해 사시도이다. 도면을 참조하면, 압축기(15)의 요동방지장치는 메인요동방지수단(20)과 보조요동방지수단(30)으로 이루어진다. Figure 3 is an exploded perspective view showing the shaking device of the compressor. Referring to the drawings, the shaking device of the compressor 15 is composed of a main shaking prevention means 20 and the auxiliary shaking prevention means (30).

메인요동방지수단(20)은 내부 진동으로 인해 압축기(15)가 요동하는 것을 방지하기 위한 것으로서, 여기서 말하는 내부 진동이란 냉매를 반복적으로 흡입, 압축, 및 배출하는 압축기가 냉매를 고온 고압으로 압축시키는 과정 중에 발생하는 진동을 말한다. 따라서, 이러한 메인요동방지수단(20)을 케이싱(10)과 압축기(15) 사이에 개재함으로써 압축기(15)의 요동에 의한 배관(16)의 손상을 방지하게 된다.The main oscillation preventing means 20 is to prevent the compressor 15 from shaking due to internal vibration, and the internal vibration referred to herein refers to a compressor that repeatedly sucks, compresses, and discharges the refrigerant to a high temperature and high pressure. Refers to vibrations that occur during the process. Therefore, the main fluctuation preventing means 20 is interposed between the casing 10 and the compressor 15 to prevent damage to the pipe 16 due to the fluctuation of the compressor 15.

메인요동방지수단(20)은 압축기(15) 저면에 확장 마련된 브라켓(22)과 상기 케이싱(10)의 바닥을 관통하도록 마련되는 고정 볼트(24)와, 상기 브라켓(22)과 케이싱(10)의 사이에 개재됨과 동시에 볼트(24)가 관통하도록 마련된 방진 고무(26)와, 상기 브라켓(22)의 관통공(23)을 관통한 볼트(24)의 단부에 결합되는 너트(28)로 이루어진다. The main fluctuation preventing means 20 includes a bracket 22 extended to the bottom of the compressor 15 and a fixing bolt 24 provided to penetrate the bottom of the casing 10, the bracket 22 and the casing 10. And a nut 28 coupled to an end portion of the bolt 24 penetrating through the through hole 23 of the bracket 22 and a dustproof rubber 26 interposed between the bolts 24 and the bolt 24. .

보조요동방지수단(30)은 외부 진동에 의해 압축기(15)가 요동하는 것을 방지하기 위한 것으로서, 여기서 외부 진동이란 압축기(15)가 운반과 같은 외부 환경 변화에 흔들리는 것을 말한다. 상술한 바와 같이, 이 외부 진동은 메인요동방지수단(20)에 설정되는 최대 응력값인 140MPa을 초과하는 값을 말하는 것으로서, 이 응력값을 초과한 과다 응력이 압축기에 가해진 경우에는, 압축기(15)의 진동이 배관(16)에 전달되어 크랙 등을 형성시킴으로써 냉매 누출을 유발하게 된다. The auxiliary oscillation preventing means 30 is to prevent the compressor 15 from shaking due to external vibration. Here, the external vibration means that the compressor 15 is shaken by an external environment change such as transportation. As described above, this external vibration refers to a value exceeding 140 MPa, which is the maximum stress value set in the main swing preventing means 20, and when an excessive stress exceeding this stress value is applied to the compressor, the compressor 15 Vibration is transmitted to the pipe 16 to form a crack or the like, causing the refrigerant to leak.

도 4는 본 발명의 일 실시예에 따른 보조요동방지수단을 도시한 것이다. 도면을 참조하면, 보조요동방지수단(30)은 소정의 고정 볼트(32)와 이 볼트(32)의 끝단에 설치되는 방진 캡(34)으로 이루어진다. 볼트(32)는 케이싱(10)의 바닥에 용접 등과 같은 방식에 의해 고정 설치된다. Figure 4 illustrates an auxiliary rocking prevention means according to an embodiment of the present invention. Referring to the drawings, the auxiliary rocking prevention means 30 is composed of a predetermined fixing bolt 32 and a dustproof cap 34 installed at the end of the bolt 32. The bolt 32 is fixed to the bottom of the casing 10 by welding or the like.

방진 캡(34)은 통상의 고무 재질로 이루어져 외부 진동시 볼트(32)로 전달되는 진동을 완충시키게 된다. 이를 위해, 방진 캡(34)의 내부에는 볼트(32) 끝단이 인입되는 요홈부(36)가 마련되며, 볼트(32)에는 방진 캡(34)과의 결합을 제한하는 단턱부(38)가 마련된다. Dust cap 34 is made of a conventional rubber material to cushion the vibration transmitted to the bolt 32 during external vibration. To this end, the groove 36 is provided in the end of the anti-vibration cap 34, the end of the bolt 32 is provided, the stepped portion 38 to limit the coupling with the anti-vibration cap 34 is provided in the bolt 32 Prepared.

본 실시예에 따르면, 보조요동방지수단(30)은 도 5에 도시된 바와 같이 평상시에는 소정 거리(S) 이격되어 있다가 과도한 외부 진동이 발생할 경우에는 압축기(15)와 케이싱(10)의 바닥을 접촉시키도록 마련된다. 이것은 보조요동방지수단(30)이 메인요동방지수단(20)과 마찬가지로 압축기(15)와 케이싱(10)의 바닥을 항상 접촉시키게 되면 평상시의 진동이 케이싱(10)에 전달될 수 있기 때문이다. 따라서, 이와 같이 보조요동방지수단(30)을 압축기(15)와 이격 설치함으로써 과도한 외부 응력이 발생할 경우에만 작용하도록 할 수 있다.According to the present embodiment, the auxiliary oscillation preventing means 30 is normally spaced a predetermined distance S as shown in FIG. 5, but when excessive external vibration occurs, the bottom of the compressor 15 and the casing 10 are separated. It is provided to contact. This is because the auxiliary oscillation preventing means 30 can always transmit the vibration to the casing 10 when the compressor 15 and the bottom of the casing 10 are always in contact with each other, as in the main oscillation preventing means 20. Thus, by installing the auxiliary oscillation preventing means 30 spaced apart from the compressor 15 in this way it is possible to act only when excessive external stress occurs.

또한, 이러한 보조요동방지수단(30)은 압축기(15)의 요동을 어느 방향으로도 지지할 수 있도록 복수개로 이루어지는데, 통상적으로 복수개로 이루어지는 상기 메인요동방지수단(20)의 사이사이에 마련됨으로써 압축기의 과다 진동을 효율적으로 방지하게 된다. In addition, the auxiliary oscillation preventing means 30 is composed of a plurality of so as to support the swing of the compressor 15 in any direction, it is provided between the main oscillation preventing means 20 which is usually made of a plurality To avoid excessive vibration of the compressor effectively.

도 6는 본 발명의 다른 실시예에 따른 보조요동방지수단을 도시한 단면도이다. 도면을 참조하면, 이 보조요동방지수단(40)은 상술한 일 실시예의 보조요동방지수단(30)과 마찬가지로 소정의 고정 볼트(42)와 고무재질의 방진 캡(44)으로 이루어지는 것은 동일하나 다음의 점에 있어서 상이하다. 6 is a cross-sectional view showing the auxiliary rocking prevention means according to another embodiment of the present invention. Referring to the drawings, the auxiliary oscillation preventing means 40 is the same as the auxiliary oscillation preventing means 30 of the above-described embodiment is made of a predetermined bolt 42 and the rubber dustproof cap 44 of the same, but the following It differs in the point of.

볼트(42)는 플랜지(43)와 나사 결합되어 케이싱(10)의 바닥에 마련되는 관통공(미도시)에 고정 설치되며, 방진 캡(44)은 내부에 볼트(42)의 끝단이 인입되는 요홈부(46)를 구비하여 볼트(42)와 결합된다. 또한, 요홈부(46)의 내경과 볼트(42) 끝단의 직경은 서로 다르게 마련되고, 그 사이에는 탄성부재(49)가 개재된다. The bolt 42 is screwed to the flange 43 and fixedly installed in a through hole (not shown) provided at the bottom of the casing 10, and the dust cap 44 has an end of the bolt 42 inserted therein. The groove 46 is coupled to the bolt 42. In addition, the inner diameter of the recess 46 and the diameter of the end of the bolt 42 are provided different from each other, the elastic member 49 is interposed therebetween.

즉, 이러한 보조요동방지수단(40)은 방진 캡(44)이 볼트(42)와 완전히 밀착 결합된 상태가 아니라, 내부에 직경차에 의한 유격이 형성되어 탄성부재(49)가 개재되고, 이 탄성부재(49)의 탄성력에 의해 방진 캡(44)과 볼트(42)가 상하로 소정거리(S) 이격 형성된다. That is, the auxiliary fluctuation preventing means 40 is not in a state in which the dust cap 44 is tightly coupled to the bolt 42, but a clearance is formed by a diameter difference therein, and the elastic member 49 is interposed therebetween. By the elastic force of the elastic member 49, the dust cap 44 and the bolt 42 are formed spaced apart a predetermined distance (S) up and down.

따라서, 본 실시예의 보조요동방지수단(40)은 상기 일 실시예와 달리 탄성부재(49)가 방진 캡(44)을 압축기(15)측으로 탄성 바이어스하기 때문에, 보조요동방수단(40)이 압축기(15)에 접촉되도록 설치된다. 그래서, 평상시에는 탄성부재(49)가 진동을 완충시키지만, 과도한 외부 진동이 발생하게 되면 방진 캡(44)과 볼트(42)의 끝단(48)이 서로 접촉됨으로써 보조요동방지수단(40)이 압축기(15)를 흔들리지 않도록 지지하게 된다. Therefore, the auxiliary oscillation preventing means 40 of the present embodiment, unlike the above embodiment, since the elastic member 49 elastically biases the dust cap 44 toward the compressor 15, the auxiliary oscillating means 40 is a compressor. It is installed to contact 15. Thus, the elastic member 49 buffers the vibration in normal times, but when excessive external vibration occurs, the dust cap 44 and the end portion 48 of the bolt 42 come into contact with each other, thereby preventing the auxiliary swing means 40 from being compressed. It will support 15 so as not to shake.

이상 상세히 설명한 바와 같이, 본 발명에 따른 압축기의 요동방지장치는 압축기의 운전에 의해 발생하는 내부 진동은 메인요동방지수단으로, 제품 운반과 같은 외부 진동에 의해 발생하는 진동은 보조요동방지수단으로 방지할 수 있기 때문에 압축기의 설치 상태를 안정적으로 유지할 수 있다. As described in detail above, in the vibration preventing device of the compressor according to the present invention, the internal vibration generated by the operation of the compressor is prevented by the main fluctuation means, and the vibration generated by the external vibration such as the product transport is prevented by the auxiliary fluctuation prevention means. As a result, the installation state of the compressor can be maintained stably.

또한, 보조요동방지수단은 평상시에는 압축기와 케이싱을 직접 접촉시키지 않고 있다가 과도한 외부 진동이 발생할 경우에만 접촉시키기 때문에, 압축기에서 발생하는 불필요한 진동을 케이스로 전달하지 않는다.In addition, the auxiliary oscillation preventing means does not normally contact the compressor and the casing, but only when excessive external vibration occurs, so that unnecessary vibration generated in the compressor is not transmitted to the case.
