It would be.

도 1에서는 임펠러(12)와 디퓨저(14)가 압축기 하우징(10)으로부터 분리되어 있는 모습이 개략적으로 도시되어 있다.1 schematically shows the impeller 12 and the diffuser 14 being separated from the compressor housing 10.

도면에서 보듯이, 냉동기의 한 구성 요소인 압축기에서, 압축기 하우징(10)의 내부에는 임펠러(12)와 디퓨저(14)가 수용되는 상태로 각각 결합된다. As shown in the figure, in the compressor, which is a component of the refrigerator, the impeller 12 and the diffuser 14 are respectively coupled to the inside of the compressor housing 10 in a state where the compressor is accommodated.

구체적으로, 상기 임펠러(12)는 사전 설치되어 있는 압축기 하우징(10) 내의 회전축(16)과 결합된다. 상기 디퓨저(14)는 임펠러(12)의 전방에 배치되는 상태로 고정되는데, 이때 상기 디퓨저(14)의 외면 둘레에 형성된 플랜지(15a)의 결합공(15b)으로 결합되는 체결부재(15c)가 압축기 하우징(10)의 체결공(17)으로 체결 조임 되는 구조를 통해 디퓨저(14)가 고정된다.Specifically, the impeller 12 is coupled to the rotating shaft 16 in the compressor housing 10 that is pre-installed. The diffuser 14 is fixed in a state disposed in front of the impeller 12, wherein the fastening member 15c coupled to the coupling hole 15b of the flange 15a formed around the outer surface of the diffuser 14 is The diffuser 14 is fixed through the fastening and fastening structure to the fastening hole 17 of the compressor housing 10.

It can be adjusted to the customized state. As a result, the diffuser can accurately function and maintain the compressor's efficiency and performance in an optimal state.

아래에서는 본 발명에 따른 디퓨저의 위치 조절 장치의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the position adjusting device of the diffuser according to the present invention will be described in detail.

도 2는 본 발명에 따른 냉동기의 압축기 하우징 내부를 보여주는 것으로, 위치 조절 장치가 구비된 디퓨저와 임펠러가 압축기의 하우징으로부터 분리되어 있는 모습을 나타낸 분리 사시도가 도시되어 있고, 도 3은 도 2의 결합된 상태를 나타낸 정면도이다. 아울러, 종래 기술로 설명된 도 1과 동일한 구성 요소는 동일한 부품이므로 동일 부호를 사용한다. Figure 2 shows the inside of the compressor housing of the refrigerator according to the present invention, there is shown an exploded perspective view showing a state in which the diffuser and the impeller with a position adjusting device is separated from the housing of the compressor, Figure 3 is a combination of Figure 2 It is the front view which showed the state. In addition, since the same components as those of FIG. 1 described in the related art are the same parts, the same reference numerals are used.

도면에서 보듯이, 임펠러(14)와 디퓨저(12)는 종래와 마찬가지로 압축기 하우징(10)의 내부에 수용되는 상태로 결합된다.As shown in the figure, the impeller 14 and the diffuser 12 are coupled in a state accommodated inside the compressor housing 10 as in the prior art.

본 발명에 따른 디퓨저(14)의 위치 조절 장치(20)는, 디퓨저(14)의 외면 둘레를 따라 배치된다. 이러한 위치 조절 장치(20)는 디퓨저(14)의 플랜지(15a)에 반경 방향으로 체결되는 체결로드(26)와, 상기 체결로드(26)의 머리부(28)에 구비되 는 패드(30)로 구성된다.The position adjusting device 20 of the diffuser 14 according to the present invention is disposed along the outer circumference of the diffuser 14.
