う欠点があつた。 In the case of a vacuum cleaner equipped with a conventional cyclone device, the fine dust that is centrifuged once in the cyclone body and deposited in the fine dust reservoir provided below on the downward flow flows into the fine dust reservoir. Due to the effect of the swirling air, a small amount of the particles is re-splattered and escapes from the exhaust port of the cyclone body, reducing the collection rate of the cyclone device. As a result,
This had the disadvantage that the filter for collecting fine dust installed behind it became clogged more quickly and the suction power decreased more quickly.

の後部より外部に排出される。 The operation of the above-mentioned embodiment having the above configuration will be explained next. First, when the electric blower 2 is operated, intake air containing dust flows into the coarse dust chamber 11 of the dust collection case 3 through the suction port 4, and relatively large dust, that is, coarse dust, is captured by the net filter 10. Next, the air containing fine dust that has passed through the net filter 10 enters the fine dust chamber 12, is led to the cyclone device 13 through its intake port 18, and is passed through the cylindrical portion 13.
The fine dust is rotated at high speed along the direction a, and the fine dust is separated by centrifugal force and falls by gravity from the dust drop port 26 into the fine dust reservoir 16, slides over the top surface of the protruding wall 25, and is deposited at the bottom. At this time, a part of the air swirling at high speed within the cylindrical portion 13a also flows into the fine dust reservoir section 16, but the swirling air that has flowed into the fine dust reservoir section is narrowed in correspondence with the dust fall port 26. The umbrella-shaped protruding wall 25 provided in the dust trap 16 diffuses the dust in the outer circumferential direction and weakens its swirling force, so that the fine dust deposited in the fine dust trap 16 is dispersed by the swirling air. This eliminates the need for agitation and prevents re-scattering. The air from which fine dust has been separated in this way exits the exhaust port 14 and enters the rear chamber 9, and the fine dust that could not be separated by the cyclone device 13 is removed by the fine dust capture filter 22. After that, it passes through the electric blower 2 and the main body case 1
is discharged to the outside from the rear.

フイルター２２を取外して排出する。 If a large amount of dust is captured in the dust collection case 3, the dust collection case 3 is separated from the main body case 1 and the lid 19 is opened. The fine dust is discharged from the dust disposal port 6. On the other hand, when discarding the fine dust captured in the rear chamber 9, the fine dust capturing filter 22 covering the rear opening 5 of the dust collecting case 3 is removed and discharged.

されるものではない。 In the above embodiment, the protruding wall 25 provided in the fine dust trap 16 is shaped like an umbrella.
As shown in the figure, it may be a spiral protruding wall 25', as long as it has the function of diffusing the momentum of the swirling air flowing into the fine dust trap 16 to the outside and weakening its swirling force. However, the shape is not limited to the shape of the above embodiment.
