본 발명은 배수펌프, 특히 공기조화기에 설치되는 배수펌프에 관한 것이다. The present invention relates to a drain pump, in particular a drain pump installed in an air conditioner.

공조기의 실내 유닛은, 냉방운전시에 열교환기에 공기 중의 수분이 응축하여 부착되어, 열교환기의 아래쪽에 설치되는 드레인 팬 내로 떨어진다. 이 드레인 팬 내에 고인 응결수를 배수하기 위하여 배수펌프가 사용된다. 이 배수펌프는, 하부에 흡입구를 형성하고, 상부를 개구함과 동시에, 옆쪽에 토출구를 설치한 펌프 본체인 하우징 내에 날개를 회전 자유롭게 설치하고, 이 날개를 하우징의 개구의 상부에 커버를 거쳐 고정한 모터에 의하여 회전시키고 있다. 상기 모터의 구동축은, 커버에 형성된 관통구멍을 회전 자유롭게 관통하여 날개의 샤프트부에 연결되고, 모터를 구동하여 날개가 회전하면 드레인 팬 내에 저류된 응결수는 흡입구 날개의 하단으로부터 흡입되어 원심력에 의하여 하우징 내면을 따라 양수되고, 케이싱의 토출구로부터 외부로 토출된다. The indoor unit of the air conditioner condenses and attaches moisture in the air to the heat exchanger during the cooling operation, and falls into the drain pan provided below the heat exchanger. A drain pump is used to drain the condensed water that has accumulated in this drain pan. The drain pump has a suction port formed at the lower part, opens the upper part, and freely rotates the vane in a housing, which is a pump main body provided with a discharge port at the side, and fixes the vane through the cover at the upper part of the opening of the housing. It is rotating by a motor. The drive shaft of the motor rotates freely through the through hole formed in the cover and is connected to the shaft portion of the blade. When the blade is rotated by driving the motor, the condensed water stored in the drain pan is sucked from the lower end of the inlet blade and is driven by centrifugal force. It is pumped along the inner surface of the housing and discharged to the outside from the discharge port of the casing.

이와 같은 배수펌프는, 예를 들면 본 출원인에 관한 특허문헌 1에 개시되어 있다. Such a drain pump is disclosed by patent document 1 which concerns on this applicant, for example.
