본 고안은 배수펌프의 임펠러에 관한 것으로, 더욱 상세하게는 배수펌프에서 양수시 물의 저항을 현저하게 감소시키어 양수량을 극대화할 수 있는 배수펌프의 임펠러에 관한 것이다.The present invention relates to the impeller of the drain pump, and more particularly to the impeller of the drain pump that can maximize the amount of water by significantly reducing the resistance of the water when pumping in the drain pump.

이미 공지된 바와 같이, 시스템 공기 조화기의 실내 유니트는 냉방 가동시 공기중에 있는 수분이 열교환기에서 물방울로 응축되어 열교환기 하부에 있는 배수팬으로 떨어지며, 이 배수팬에 고인 물은 배수펌프로 방출하도록 되어 있다.As is already known, the indoor unit of the system air conditioner condenses moisture in the air into water droplets in the heat exchanger and drops into the drain pan under the heat exchanger during cooling operation, and the water accumulated in the drain pan is discharged by the drain pump. It is supposed to be.

도 1에 도시된 배수펌프는 모터(1)와 브라켓트(12)에 이 모터(1)의 하단에 연결된 펌프 본체(13)로 구성되고, 상기 펌프 본체(13)는 펌프실(9)과 흡입구(10)와 배수구(11)를 갖춘 펌프 하우징(14)으로 이루어지며, 상기 펌프 하우징(14)은 회전축(3)과, 이 회전축(3)의 중심부에서 평판형이면서 방사상으로 뻗어 있는 복수개의 소경날개(5) 및 대경날개(4)를 갖춘 임펠러(100)를 갖추고 있다.The drain pump shown in FIG. 1 comprises a pump body 13 connected to a motor 1 and a bracket 12 at the lower end of the motor 1, and the pump body 13 includes a pump chamber 9 and an inlet ( 10) and a pump housing (14) having a drain (11), wherein the pump housing (14) comprises a rotating shaft (3) and a plurality of small-sized vanes extending radially at the center of the rotating shaft (3). And an impeller 100 having a large blade 4.

따라서 배수펌프 작동시 흡입구(10)로 빨아올린 물은 화살표 방향을 따라 이동하여 회전하는 임펠러(100)를 거쳐 배수구(11) 쪽으로 방출하도록 되어 있다.Therefore, the water sucked into the suction port 10 during the operation of the drain pump is to be discharged toward the drain port 11 through the impeller 100 to rotate in the direction of the arrow.

한편, 종래 임펠러(100)는 도 5에 도시된 바와 같이 대경날개(105)의 외주면에 링형상으로 감싸는 일부 절개된 원통형 벽부재(107)과 이 원통형 벽부재(107)에 연결된 중심축의 하방으로 갈수록 폭이 감소하는 둥근 접시 모양을 갖는 환상부재(115)로 연결되고, 이 환상부재(115)의 일부를 절개하여 양수를 공급하는 구조로 되어 있는데, 이러한 종래 임펠러 구조는 상기 환상부재(115)에서 물의 저항을 야기하여 원활한 양수 효율을 얻을 수 없는 단점이 있으며, 또한 도 6에 도시된 종래 다른 임펠러도 도 5에 도시된 종래 임펠러와 같은 문제점을 지니고 있었다.Meanwhile, as shown in FIG. 5, the conventional impeller 100 is partially cut in the cylindrical wall member 107 wrapped in a ring shape on the outer circumferential surface of the large-diameter wing 105 and downward of a central axis connected to the cylindrical wall member 107. It is connected to the annular member 115 having a round plate shape that gradually decreases in width, and has a structure in which a part of the annular member 115 is incised to supply amniotic fluid. There is a disadvantage that a smooth pumping efficiency can not be obtained by causing the resistance of the water, and also another conventional impeller shown in FIG. 6 had the same problem as the conventional impeller shown in FIG.

이에 본 고안은 종래와 같은 문제점을 해결하기 위해 안출된 것으로, 배수펌프 가동시 물의 저항을 현저하게 감소시키어 양수량을 증대할 수 있는 개선된 배수펌프의 임펠러를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems as described above, and an object of the present invention is to provide an impeller of an improved drainage pump that can increase the amount of water by significantly reducing the resistance of the water when the drainage pump is operated.

상기와 같은 목적을 달성하기 위한 본 고안은 모터의 구동축에 연결되는 회전축과, 이 회전축의 일측에 등간격으로 방사상으로 배치되는 복수의 대경날개, 이 대경날개들 사이에 방사상으로 배치되는 복수의 소경날개, 상기 대경날개들과 연결되면서 회전축의 하부에 연결되는 보조날개 및, 상기 대경날개와 소경날개의 외주연을 연결하는 원통형 벽부재로 이루어진 배수펌프의 임펠러에 있어서, 상기 원통형 벽부재에는 대경날개와 소경날개를 서로 연결시켜 주는 환상형의 링이 이 원통형 벽부재와 동심원적으로 안쪽으로 배치되어 형성되어 있다.The present invention for achieving the above object is a rotary shaft connected to the drive shaft of the motor, a plurality of large diameter blades radially disposed at equal intervals on one side of the rotary shaft, a plurality of small diameter radially disposed between the large diameter wings In the impeller of the drain pump consisting of a wing, a secondary wing connected to the lower portion of the rotating shaft and connected to the large diameter wings, and a cylindrical wall member connecting the outer circumference of the large diameter wing and the small diameter wing, the cylindrical wall member in the large diameter wing An annular ring which connects the small wing with each other is formed concentrically inward with the cylindrical wall member.

이하, 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail based on the accompanying drawings.

도 1은 본 고안에 따른 임펠러가 배수펌프에 장착된 상태를 나타낸 사용 상태도이고, 도 2 내지 도 4는 본 고안에 따른 임펠러의 부분절개 사시도와 측면도 및 평면도이다.1 is a use state diagram showing a state in which the impeller according to the present invention is mounted on the drain pump, Figures 2 to 4 is a partial cutaway perspective view and a side view and a plan view of the impeller according to the present invention.

본 고안은 도면에 도시된 바와 같이 모터(1)의 구동축(2)에 연결되는 회전축(3)과, 이 회전축(3)의 일측에 등간격으로 방사상으로 배치되는 다수의 대경날개(4), 이 대경날개(4)들 사이에 등각도의 방사상으로 배치되는 소경날개(5), 이 대경날개(4)들과 연결되면서 회전축(3)의 하부에 연결되는 보조날개(6) 및, 상기 대경날개(4)와 소경날개(5)의 외주연을 연결하는 원통형 벽부재(7)로 이루어진 배수펌프의 임펠러에 있어서, 상기 원통형 벽부재(7)의 안쪽에는 대경날개(4)와 소경날개(5)들을 서로 연결해 주는 환상형의 링(8)이 이 원통형 벽부재(7)와 동심적으로 배치되어 형성된 구조로 되어 있다.The present invention is a rotary shaft 3 connected to the drive shaft 2 of the motor 1, as shown in the drawing, and a plurality of large-diameter wings 4 radially disposed at equal intervals on one side of the rotary shaft 3, Small-diameter wings 5 are radially disposed between the large-diameter wings 4, auxiliary blades 6 connected to the lower axis of the rotary shaft 3 while being connected to the large-diameter wings 4, and the large diameter. In the impeller of the drain pump consisting of a cylindrical wall member (7) connecting the outer periphery of the blade (4) and the small diameter wing (5), inside the cylindrical wall member (7) a large diameter wing (4) and a small diameter wing ( An annular ring 8 which connects 5 to each other is arranged concentrically with this cylindrical wall member 7.

즉 본 고안에 따른 임펠러는 회전축(3)에 직접 연결되어 방사상 방향으로 배치되는 대경날개(4)와 이 회전축(3)에 이격되어 방사상 방향으로 배치되는 소경날개(5)들의 외주연을 원통형 벽부재(7)로 연결시키고, 이 원통형 벽부재(7)와 동심원으로 안쪽에 배치되는 환상형의 링(8)으로 이들 대경날개(4)와 소경날개(5)를 연결시킨 구조를 갖춤에 따라 종래와 같이 환상부재를 완전히 제거함에 따라 소음감소와 양수 효율의 증대를 추구할 수가 있다.In other words, the impeller according to the present invention is a cylindrical wall having the outer circumference of the large-diameter wings 4 which are directly connected to the rotary shaft 3 and disposed in the radial direction and the small-diameter wings 5 which are spaced apart from the rotary shaft 3 and disposed in the radial direction. By connecting the member 7 and having a structure in which these large diameter blades 4 and the small diameter blades 5 are connected by an annular ring 8 arranged concentrically with the cylindrical wall member 7. By completely removing the annular member as in the prior art, it is possible to seek noise reduction and increase of pumping efficiency.

이어 본 고안의 작용을 설명한다.Next, the operation of the present invention will be described.

모터(1)의 구동력이 구동축(2)으로 전달되면, 임펠러(100)가 회전하게 되고. 이 임펠러(100)의 회전하는 보조날개(6)에 의하여 펌프실(9)의 흡입구(10)로 유입된 물은 대경날개(4)와 소경날개(5) 사이를 통하여 이송되어 이 대경날개(4)와 소경날개(5)에 부딪히면서 펌프실(9)의 배수구(11)을 통하여 도 1의 화살표 방향처럼 외부로 배출되어 진다.When the driving force of the motor 1 is transmitted to the drive shaft 2, the impeller 100 is rotated. The water flowing into the suction port 10 of the pump chamber 9 by the auxiliary auxiliary blades 6 of the impeller 100 is transported between the large-diameter blade 4 and the small-diameter blade 5, and the large-diameter blade 4 ) And the small diameter wing (5) is discharged to the outside through the drain hole 11 of the pump chamber (9) as shown in the arrow direction of FIG.

상기와 같이 본 고안에 따른 배수펌프의 임펠러는 종래의 임펠러에서 물의 흐름저항을 야기하는 둥근접시모양을 갖는 환상부재를 제거한 개량된 개선 구조를 갖춤에 따라, 이 임펠러로 유입되는 양수의 흐름저항을 최소화하여 양수효율을 증대시키며, 구조의 단순화로 작동시 소음저감 효과도 갖는 잇점이 있다.As described above, the impeller of the drain pump according to the present invention has an improved improvement structure in which the annular member having the round plate shape causing the flow resistance of water in the conventional impeller has been improved, thereby improving the flow resistance of the amniotic fluid flowing into the impeller. Minimization increases pumping efficiency, and the structure has the advantage of reducing noise during operation.
