IMPELLER AND VACUUM CLEANER MOTOR ASSEMBLY HAVING THE SAME

摘要

PURPOSE: An impeller and a motor assembly of a vacuum cleaner including the same are provided to improve work reliability of the impeller and work efficiency by connecting an upper blade integrally connected on an upper plate and a lower blade integrally connected on a lower plate, forming the impeller, and preventing the stress concentration. CONSTITUTION: An impeller comprises an upper plate (21) and a lower plate (22). The upper plate is integrally formed with an upper blade (21a). A lower blade (22a) where a connecting groove (22b) corresponded to connect the upper blade is formed in the inside is integrally formed at the lower plate. The upper plate and the lower plate are connected in order that the upper blade is inserted into the connecting groove of the lower blade.
