Abstract: 본 발명은 다방향 배출이 가능한 날개없는 선풍기에 관한 것으로, 보다 상세하게는, 날개없는 선풍기이 내부에 각각의 바람을 생성하여, 각각의 바람이 배출되도록 하는 구조를 통해 선풍기의 본연의 목적을 그대로 유지함과 동시에, 바람의 생성 시 흡입력을 높일 수가 있어 배출되는 바람을 증폭되어 보다 강한 바람 및 최종적으로 외부로 배출되는 바람이 수평방향으로 360°모두에 걸쳐 배출되되 균일하게 배출되어 불필요한 회전구조를 갖지 않아도 되어 경제적 효율성과 사용자에게 시원함을 제공하고, 나아가 받침대를 통해 선택적으로 높이 조절을 하여 사용상의 편리성을 부여할 수 있는 유용한 발명이다.

Abstract: A compressor is provided for use in domestic appliances. The compressor comprises: an impeller comprising an inlet, an outlet, a hub defining a rotational axis of the impeller, a plurality of impeller blades that extend from the hub, and a shroud that at least partially surrounds the impeller blades; a housing that at least partially surrounds the shroud and that is coaxially arranged with respect to the rotational axis of the impeller to allow the impeller to rotate within the housing; a leakage flow path defined between the shroud and the housing leading from a leakage flow path inlet to a leakage flow path outlet; a labyrinth seal arrangement provided in the leakage flow path; and a flow straightening arrangement having an inlet at an outlet of the labyrinth seal arrangement.
