<P>PROBLEM TO BE SOLVED: To provide a dust collecting bag for a vacuum cleaner which can avoid or suppress a pressure loss caused by an impermeable part, while following a technique of sucked air control by the impermeable part of which the structure and attachment and detachment are simple. <P>SOLUTION: The dust collecting bag includes an inlet side bag wall 5 which has an inlet 1, 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 a shaft 6x which is formed on the sucked-in side bag wall 2, in projection toward the inlet. A disk-shaped air flow control guide 6, having a projecting part 400 which performs diversion of intake air sucked in from the inlet 1 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, is provided rotatably on the shaft 6x. By the projecting part 400 of the air flow control guide 6, the diversion of the intake air flowing in from the inlet 1 is performed, with a high flow diversion strength, in two or more specified directions, e.g. in the upward and downward and right and left directions, or in the direction of the whole of the periphery, toward the lateral periphery bag wall from the central part of the projecting part, so as to produce a strong inverted air flow toward the inlet side bag wall 5, and thus dust collection performance can be improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
