Zusammenfassung: | Disclosed is a vacuum cleaner capable of effectively changing the direction of flow toward a diffuser and reducing loss caused by flow separation. The vacuum cleaner comprises a suction unit inside a body, wherein: the suction unit comprises an impeller arranged such that air is suctioned in response to the rotation around a shaft, and a plurality of diffuser vanes arranged such that air discharged from the impeller is guided; and the diffuser vanes are provided as one vane body of which the cross section has the shape of an air foil, and include a passage provided to cross through at least a portion of the vane body.
La présente invention concerne un aspirateur pouvant modifier efficacement la direction de l'écoulement vers un diffuseur et réduire la perte causée par la séparation de l'écoulement. L'aspirateur comprend une unité d'aspiration à l'intérieur d'un corps, l'unité d'aspiration comportant une roue disposée de manière à aspirer l'air en réponse à la rotation autour d'un arbre, et une pluralité d'aubes de diffuseur disposées de manière à guider l'air expulsé de la roue ; et les aubes de diffuseur étant constituées d'un corps d'aube dont la section transversale prend la forme d'un déflecteur d'air, et comportant un passage prévu pour traverser au moins une partie du corps d'aube.
디퓨져로 유입된 유동의 방향을 효과적으로 전환하고, 유동 박리에 의한 손실을 줄일 수 있는 진공청소기를 개시한다. 본체 내부에 흡입유닛을 포함하는 진공청소기에 있어서, 흡입유닛은, 축을 중심으로 회전함에 따라 공기를 흡입하도록 배치되는 임펠러와, 임펠러에서 토출되는 공기를 가이드 하도록 배치되는 복수의 디퓨져베인을 포함하고, 디퓨져베인은, 그 단면이 에어 포일 형상인 하나의 베인 바디로 마련되되, 베인 바디의 적어도 일부를 가로지르도록 관통하여 마련되는 통로를 포함한다. |
