<p>PROBLEM TO BE SOLVED: To solve the problem in a conventional technique in which the arrangement of a spiral channel and a partitioning board to reduce noise from the air suction side of an electric blower increases the fluid resistance of an air course and reduces suction force.SOLUTION: A vacuum cleaner includes: an electric blower; a dust collection device arranged on the upstream side of the electric blower; and a communication component for allowing the dust collection device to communicate with the electric blower. The communication component includes: a dust collection device side surface having a dust collection device side opening that faces the dust collection device; an electric blower side surface having an electric blower side opening that is nearly vertical to the dust collection device side surface and faces the electric blower; and a first surface that faces the dust collection device side surface. The dust collection device side surface includes a second surface on the opposite side of the electric blower side surface with respect to the dust collection device side opening.</p> |
