• the air vent 323 in the dust chamber and closing the air vent 323 with the fourth dust removing filter 324 of the metal mesh, it is possible to secure the secondary air path 29 b which is the second air path. it can. Therefore, as described in the second embodiment, when dust is sucked, the coarse dust 51 is captured by the dust storage portion 24. Therefore, an air path is secured around the first dust removal filter 27a and the second dust removal 27b. , You can prevent the decrease in air volume.
• the second dust removal filter 27b is recovered by rolling up the fine dust 51 during cleaning. It is possible to prevent adhesion, and it is possible to more effectively prevent the reduction of the air volume passing through the first air passage main air passage 29a and the second air passage second air passage 29b.
• the vacuum cleaner according to the present invention can provide a vacuum cleaner in which suction power is unlikely to be reduced even when suctioning dust while securing high suction work rate. This makes it possible to greatly reduce maintenance work such as filter cleaning and dust discharge, and it can be used for various types of vacuum cleaners such as commercial vacuum cleaners, which can be handled only with household vacuum cleaners.
