Problems solved by technology
However, since the non-ventilated part greatly blocks the ventilation area of the suction side of the dust bag, the ventilation resistance, that is, the pressure loss is large.
In addition, due to the small ventilation area, it is prone to clogging
If the pressure loss is large, the suction capacity of the electric vacuum cleaner will decrease, so it is necessary to increase the load capacity of the blower
In addition, in order to reduce the pressure loss, it is necessary to use the breathable part of the dust bag to make up for the lack of ventilation area caused by the non-ventilated part.
That is, since the total area of the dust bag increases, the size of the dust bag increases and the cost increases

The present invention provides a dust collector and an electric dust collector with the same. The dust collection bag is composed of the following components: a suction port side bag wall with a suction port, a sucked side bag wall which is opposite with the suction port side bag wall, and a side periphery bag wall which is formed between the suction port side bag wall and the sucked side bag wall. The dust collection bag is provided with an air flow control guiding member at the sucked side bag wall. The air flow control guiding member is provided with a projection which generates reversing air flow which faces the suction port side bag wall through shunting the suction air that is sucked from the suction port to the side periphery bag wall. Through the reversing air flow, the dust is sucked efficiently at the suction port side bag wall side. Furthermore the suction air which becomes the reversing air flow is discharged to the outside of the dust collection bag through a ventilation part. Therefore, the blocking of the sucked side bag wall can be prevented, and furthermore the increase of pressure loss is suppressed.
Description
technical field [0001] The present invention relates to a dust collecting bag for an electric vacuum cleaner and an electric vacuum cleaner using the dust collecting bag. Background technique [0002] As an electric vacuum cleaner using a dust bag, for example, the electric vacuum cleaner described in Unexamined-Japanese-Patent No. 2002-291663 (patent document 1) is demonstrated. The electric vacuum cleaner described in Patent Document 1 accommodates a dust collecting bag having a suction port in a dust collecting chamber. The direction of the suction wind entering from the suction port is obliquely eccentric with respect to the axis of the suction port. As a result, the suction wind forms a swirling flow along the side peripheral bag wall toward the suctioned side bag wall facing the suction port. The swirling flow of the suction wind centrifugally separates the dust accompanying the suction wind. As a result, the dust collection rate on the side peripheral bag wall can ...
