Description

회전압축기의 어큐뮤레이터 고정부재Accumulator fixing member of rotary compressor

본 고안은 공기조화기 등에 장착되는 회전압축기에 관한 것으로, 더욱 상세하게는 밀폐용기의 외부에 어류뮤레이터를 고정하는 고정부재에 관한 것이다.The present invention relates to a rotary compressor mounted on an air conditioner and the like, and more particularly, to a fixing member for fixing a fish mutor to the outside of a sealed container.

일반적으로 회전압축기는 냉매를 매개체로 하여 압축, 응축, 팽창, 증발과정이 연속적으로 수행되는 공기조화기 등의 냉동사이클에서 냉매를 고온 고압으로 압축하여 외부로 내보내는 작용을 한다.In general, the rotary compressor serves to compress the refrigerant to a high temperature and high pressure in a refrigeration cycle such as an air conditioner in which the compression, condensation, expansion, and evaporation processes are continuously performed using the refrigerant as a medium.

이러한 기능을 하는 일반적인 회전압축기는 도 1에 도시한 바와 같이, 밀폐용기(1)에 구동부(미도시)와 압축부(미도시)가 내장되어 있고, 어큐뮤레이터(2)를 통해 기화냉매를 흡입 압축하여 외부로 토출하도록 구성되어 있다.As shown in FIG. 1, a general rotary compressor having such a function includes a driving unit (not shown) and a compression unit (not shown) in the airtight container 1, and vaporize refrigerant through the accumulator 2. It is configured to suction and discharge to the outside.

원통형 케이싱(2a)으로 이루어진 어큐뮤레이터(2)는 일단부가 케이싱(2a)의 저부와 연통되고 타단부는 밀폐용기(1)와 연통된 냉매안내관(2b)을 통해 밀폐용기(1)로 냉매의 유입을 안내하며, 이것은 금속재질의 고정홀더(3b)와 유동홀더(3c)에 의해 밀폐용기(1)의 외측면에 세워설치되어 있는데 이의 고정구조는 다음과 같다. 우선, 밀폐용기(1)의 외측면에는 지지브라켓(3a)의 일단부가 용접수단에 의해 고정되어 있으며, 지지브라켓(3a)의 타단부에는 어큐뮤레이터(2)의 케이싱(2a)을 감싸도록 반원형의 고정홀더(3b)가 마련되어 있다. 그리고 고정홀더(3b)와 대응하는 형상으로 이루어져 양단부가 스크류(3d)체결됨으로써, 케이싱(2a)을 감싸는 유동홀더(3c)가 마련되어 있다.The accumulator (2) consisting of a cylindrical casing (2a) has one end communicating with the bottom of the casing (2a) and the other end passing through the refrigerant guide tube (2b) communicating with the hermetically sealed container (1). It guides the inflow of the coolant, which is installed on the outer surface of the sealed container 1 by the metal holder (3b) and the flow holder (3c), the fixing structure thereof is as follows. First, one end of the support bracket 3a is fixed to the outer side of the sealed container 1 by welding means, and the other end of the support bracket 3a surrounds the casing 2a of the accumulator 2. Semi-circular fixed holder 3b is provided. In addition, a floating holder 3c surrounding the casing 2a is provided by forming a shape corresponding to the fixing holder 3b and fastening both ends by screws 3d.

따라서 어큐뮤레이터(2) 케이싱(2a) 외측면을 고정홀더(3b)에 밀착하고, 유동홀더(3c)의 스크류홀(미도시)을 고정홀더(3b)의 양단부에 천공된 스크류홀(미도시)을 일치시킨 후, 스크류(3d)를 체결하면, 고정홀더(3b)와 유동홀더(3c)에 케이싱(2a)이 감싸져 견고하게 고정된다.Accordingly, the screw hole (not shown) is brought into close contact with the outer surface of the accumulator 2 casing 2a to the fixed holder 3b, and the screw holes (not shown) of the floating holder 3c are drilled at both ends of the fixed holder 3b. After the coincidence, the screw 3d is fastened, and the casing 2a is wrapped around the fixed holder 3b and the floating holder 3c to be firmly fixed.

그러나 어큐뮤레이터(2)를 고정하기 위한 고정홀더(3b)와 유동홀더(3c)가 금속재질로 이루어져 있고 스크류(3d)를 이용하여 체결되어 있기 때문에, 압축기의 작동중에 발생되는 진동에 의해 스크류(3d)가 풀어져 이들의 결합이 헐거워질 염려가 있다. 또한 압축기에서 발생된 진동이 지지브라켓(3a)과 고정홀더(3b)를 통해 어큐뮤레이터(2) 케이싱(2a)까지 전달되어 또다른 작동소음을 발생한다. 심한 경우에는 이러한 진동에 의해 밀폐용기(1)와 결합된 냉매안내관(2b)의 타단부가 손상되어 냉매가 누설되는 경우도 있다.However, since the fixing holder 3b and the floating holder 3c for fixing the accumulator 2 are made of metal and fastened using the screw 3d, the screw is caused by vibration generated during the operation of the compressor. There is a fear that (3d) is released and these bonds become loose. In addition, the vibration generated in the compressor is transferred to the accumulator 2 casing 2a through the support bracket 3a and the fixed holder 3b to generate another operation noise. In severe cases, the other end of the refrigerant guide pipe 2b coupled to the sealed container 1 may be damaged by the vibration, and the refrigerant may leak.

본 고안은 이러한 문제점을 해결하기 위한 것으로, 본 고안의 목적은 신축재로 이루어진 체결밴드를 이용하여 어큐뮤레이터 케이싱을 견고하게 고정함으로써 압축기의 작동중에 풀어지는 것을 방지하며, 압축기의 작동시 발생되는 진동이 어큐뮤레이터로 전달되는 것을 억제하여 압축기의 작동소음을 저감하는 회전압축기의 어큐뮤레이터 고정부재를 제공하는 것이다.The present invention is to solve this problem, the object of the present invention is to secure the accumulator casing by using a fastening band made of a stretchable material to prevent loosening during the operation of the compressor, It is to provide an accumulator fixing member of a rotary compressor that suppresses the transmission of vibration to the accumulator to reduce the operation noise of the compressor.
