VACUUM CLEANER INCLUDING NEGATIVELY CHARGED PARTICLE GENERATOR

摘要

PROBLEM TO BE SOLVED: To solve the problem of a conventional vacuum cleaner, wherein the interior atmosphere for operating the vacuum cleaner is made offensive due to a temperature rise of discharged air. SOLUTION: This vacuum cleaner includes a negatively charged particle generator 8 disposed in an exhaust passage 4 of a fan motor 3 in a body part 1. The generator 8 is composed of a photoelectron generating material and an ultraviolet ray source for radiating ultraviolet rays to the surface of the photoelectron generating material. Thus, the air containing minus particles can be discharged without generation of ozone, so that the interior atmosphere for operating the vacuum cleaner will not be offensive. COPYRIGHT: (C)2004,JPO
