<P>PROBLEM TO BE SOLVED: To provide a dust collecting bag for a vacuum cleaner which has a high dust collection efficiency and reduces an offensive smell of exhaust air. <P>SOLUTION: The dust collecting bag includes an inlet side bag wall 5 on the side of an inlet 1 through which intake air flows in, a sucked-in side bag wall 2 which is opposite to the inlet 1, a lateral periphery bag wall 4 which forms the part between the inlet 1 and the sucked-in side bag wall 2, and an air flow control guide 6 which is provided inside the sucked-in side bag wall 2 and which performs diversion of the intake air toward the lateral periphery bag wall 4 and produces an inverted air flow toward the inlet side bag wall 5 along the lateral periphery bag wall 4. A ventilation part 7 is retained in the peripheral part of the air flow control guide 6, while a powdery material 600 having a deodorizing effect and/or an antibacterial-disinfectant effect is stored in a floating space 46 between the sucked-in side bag wall 2 and the air flow control guide 6. Since sucked air is inverted by the air flow control guide 6, dust collection is facilitated on the side of the inlet 1 in the lateral periphery bag wall 4 and, besides, the powdery material 600 is emitted into the dust collecting bag 100 from the ventilation part 7 and the deodorization and disinfection of dust 38 can be performed effectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
