PROBLEM TO BE SOLVED: To provide a noiseless electric cleaning appliance, particularly an exhaust baffle for a hand-held vacuum cleaner. SOLUTION: The electric cleaning appliance (1) includes an air flow generator (26) for generating air flow, a separator (6) for separating dirt and dust from the air flow, a power source (22) for supplying electric power to the air flow generator, at least one exhaust vent (16), and the exhaust baffle (32). The exhaust baffle includes a body (36) having an upstream face (38) and a downstream face (40), an air flow route (42) between the upstream face and the downstream face, and a plurality of blades (44) projected from the body. Each of the blades includes a first side edge (46), a second side edge (48) and a front edge (50). COPYRIGHT: (C)2010,JPO&INPIT |
