VACCUM AIR CLEANER

摘要

A vacuum cleaner is provided to reduce the noise generated by a passage resistance by sufficiently securing the area and length of a discharge passage. A vacuum cleaner includes a body, a blowing fan unit(30), an inner case(40), and an outer case(50). The blowing fan unit includes a blowing fan and a motor to generate a suction force in the interior of the body. The inner case surrounds the blowing fan unit. An interior passage is formed in the interior of the inner case. The outer case surrounds the inner case. A discharge passage communicated with the interior passage is formed between the inner case and the outer case. The discharge passage includes a rotating passage branched from the interior passage so as to rotate the air discharged from the blowing fan unit, and a bending passage guiding the air so that the air can be bent several times.
