US-7966692-B2

用于真空吸尘器,高效分离灰尘。

专利摘要

本发明涉及一种多旋风集尘器和采用该集尘器的真空吸尘器,其形成向上旋转的气流以分离污染物。用于真空吸尘器的多旋风集尘器包括:第一旋风单元,使通过第一旋风单元下部吸入的含尘空气形成第一向上旋转的气流,以通过离心力从含尘空气中分离污染物;以及第二旋风单元,设置在第一旋风单元下方,使从第一旋风单元排出并吸入第二旋风单元下部的部分清洁空气形成第二向上旋转的气流,以通过离心力从部分清洁空气中分离灰尘。

Original abstractThe present invention relates to a multi-cyclone dust collector and a vacuum cleaner employing the same that forms an upwardly whirling air current so as to separate contaminants. The multi-cyclone dust collector for the vacuum cleaner includes a first cyclone unit causing dust-laden air sucked through a lower portion of the first cyclone unit to form a first upwardly whirling air current so as to separate contaminants from the dust-laden air by centrifugal force, and a second cyclone unit disposed under the first cyclone unit and making partially clean air, which is discharged from the first cyclone unit and then sucked in a lower portion of the second cyclone unit, to form a second upwardly whirling air current so as to separate dust from the partially clean air by centrifugal force.
