VACUUM CLEANER HAVING CONNECTING PATH FOR REDUCING NOISE

摘要

A vacuum cleaner having a connecting passage for reducing noise is provided to restrict air passing through the connecting passage from colliding continuously at one place by mounting a partition at a discharge connecting hole of the connecting passage and to decrease low frequency noise by distributing air to the connecting passage and the partition. An intake connecting hole(15a) and an exhaust connecting hole(15b) are formed in a connecting passage(15) of a vacuum cleaner to guide air from a cyclone dust collector to a motor. The intake connecting hole is communicated with the cyclone dust collector, and the exhaust connecting hole is communicated with the motor. A partition is formed in the exhaust connecting hole of the connecting passage to restrict air from be concentrated at one place by centrifugal force in the connecting passage. The partition is vertically installed along the moving direction of air to minimize interference with air flow, and integrally formed with the connecting passage.
