DUST COLLECTION DEVICE AND VACUUM CLEANER

摘要

PROBLEM TO BE SOLVED: To restrain an increase in pressure loss in an air passage in a dust collection device.SOLUTION: A dust collection device 100 comprises: a first centrifugal separation part 70 that separates first dust in dust-containing air; a second centrifugal separation part 80 that is provided at an upper stage than the first centrifugal separation part 70 and separates smaller second dust than the first dust in the dust-containing air passed through the first centrifugal separation part 70; and a dust collection container 111 that collects the first and second dust. A discharge air passage from an air outflow port 83a in the second centrifugal separation part 80 to a discharge port 135 of the dust collection device 100 is provided above the second centrifugal separation part 80.
