VACUUM SUNTION UNIT

摘要

The present invention relates to a vacuum suction unit. A vacuum suction unit according to an aspect includes: a cover with an air inlet; an impeller for enabling air received through the air inlet; a motor with a shaft connected to the impeller; a guide device for guiding the air flow discharged through an outlet of the impeller; and a motor housing receiving the motor and having an air outlet. The guide device includes: a guide body arranged in a lower side of the impeller; a first guide vane formed in a lateral surface of the guide body and guiding the air discharged through the impeller; and a second guide vane formed on the underside of the guide body, connected to the first guide vane, and guiding the air moved by the first guide vane. An angle of an inlet of the first guide vane is within a range of 10-20 degrees. The purpose of the present invention is to provide vacuum suction unit capable of minimizing a flow loss by optimizing the angle of the inlet of the guide vane.
