본고안은 임펠러 조립구조에 관한 것이다.This article relates to an impeller assembly structure.

본고안을 더욱 상세히 설명하면, 임펠러에 설치되는 임펠러 날개의 상단에 형성된 결합돌기를 임펠러의 상면에 밀착되게 조립시켜 모터 회전시 임펠러의 공기저항을 감소시키고 공기의 파열을(소음)을 저하시킬수 있게한 것이다.In more detail, the present invention is to assemble the coupling protrusion formed on the upper end of the impeller blade installed on the impeller to be in close contact with the upper surface of the impeller so as to reduce the air resistance of the impeller and reduce the burst of air (noise) when the motor rotates. It is.

주지한 바와같이 종래의 임펠러는 제 5 도와 같이 임펠러(3)의 상판(31)과 하판(32) 사이에 임펠러날개(34)를 취부하는데 이 임펠러날개의 상면과 하면에 형성된 돌기(35)(35-1)를 강재 맞춤으로 끼워 또는 리벳트로 고정설치하는 것이다.As is well known, the conventional impeller mounts the impeller blades 34 between the upper plate 31 and the lower plate 32 of the impeller 3 as shown in FIG. 5 and the protrusions 35 formed on the upper and lower surfaces of the impeller blades ( 35-1) is fitted with steel fittings or fixed with rivets.

이와같이 임펠러의 상판과 하판의 외측에 돌출된 돌기에 의하여 임펠러의 고속 회전시 공기의 저항을 많이 받게되어 모터의 효율을 저하시키고, 또한 공기의 파열음을 가중시켜주므로서 결국에는 저효율의 모터에 고소음화된 모터가 생산되므로 제품의 품질을 저하시키는 결점이 있는 것이다.In this way, protrusions protruding from the upper and lower plates of the impeller receive a lot of air resistance during the high-speed rotation of the impeller, thereby degrading the efficiency of the motor and increasing the bursting sound of the air. Since the motor is produced, there is a drawback of degrading the quality of the product.

본고안은 상기와 같은 종래의 결점을 해소시키기 위하여 안출한 것으로서 임펠러날개의 결합돌기를 임펠러의 상판과 하판에 밀착되게 조립시켜 고효율의 모터와 저소음의 모터를 생산할수 있게한 것으로서 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.This proposal is to solve the above-mentioned drawbacks as described above by assembling the engaging projection of the impeller blade close to the upper and lower plates of the impeller to produce a high-efficiency motor and a low noise motor as shown in the accompanying drawings It will be described in detail as follows.

(1)은 공지의 임펠러이다. 이 임펠러(1)의 상판(2)과 하판(3)에는 다수개의 구멍(4)(4-1)을 천공하였다.(1) is a known impeller. In the upper plate 2 and the lower plate 3 of the impeller 1, a plurality of holes 4 and 4-1 were drilled.

임펠러의 상판(2)과 하판(3)에는 임펠러날개(5)가 설치되는데 이 임펠러날개(5)의 상면(6)과 저면(7)에는 본체의 두께보다 얇은 결합돌기(8)(8-1)가 다수개 형성하여 된 것이다.Impeller blades (5) are installed on the upper plate (2) and the lower plate (3) of the impeller. On the upper surface (6) and the bottom surface (7) of the impeller blades (5), the engaging protrusions (8) (8-) 1) is formed by a plurality.

이와같이 구성된 본고안은 제 3 도에 표현된 바와같이 임펠러(1)의 상판(2)과 하판(3)사이에 임펠러날개(5)를 설치하고 임펠러날개(5)의 상면(6)과 저면(7)에 다수개 형성된 결합돌기(8)(8-1)를 임펠러의 구멍(4)(4-1)에 삽입시킨후 제 3b 도와 같이 이 결합돌기(8)(8-1)를 임펠러(1)의 상판(2)과 하판(3)의 상면에 밀착되게 조립시키는 것이다.As described in FIG. 3, the present invention constructed as described above has an impeller wing 5 installed between the upper plate 2 and the lower plate 3 of the impeller 1, and the upper surface 6 and the bottom surface of the impeller wing 5 ( 7) Insert a plurality of engaging projections (8) (8-1) formed in a plurality of holes into the holes (4) (4-1) of the impeller, and then the engaging projections (8) (8-1) as shown in the 3b diagram. The upper plate 2 and the lower plate 3 of 1) are assembled in close contact with each other.

이와 같이 조립된 임펠러는 고속회전시 이 결합돌기(8)(8-1)가 상판(2)과 하판(3)에 밀착조립되어 있으므로 공기저항이 감소되고 이에 따라 공기의 파열음도 감소되는 것이다.Since the impeller assembled as described above is closely assembled to the upper plate 2 and the lower plate 3 at the time of high speed rotation, the air resistance is reduced and thus the bursting sound of the air is also reduced.

이상에서와 같이 본고안은 임펠러날개의 결합돌기를 임펠러의 상판과 하판에 밀착되게 조립설치하므로서 공기저항감소 공기의 파열음을 감소시키므로서 모터의 성능을 향상시켜 소비자로 하여금 높은 신뢰성을 얻을수 있게한 매우 실용적인 고안인 것이다.As described above, this proposal is to install the coupling protrusion of the impeller close to the upper plate and the lower plate of the impeller to reduce the air resistance to reduce the burst sound of the air to improve the performance of the motor to enable consumers to obtain high reliability It is a practical design.
