In addition, when cleaning narrow places such as door rails where the floor brush 11 cannot enter due to its width, the extension pipe 8 is detached from the cleaner main body 2 and dust is sucked in from the front end of the extension pipe 8 .

Furthermore, when cleaning the tabletop etc., the connection pipe part 6 is detached from the grip pipe part 7, and dust is sucked in from the front-end|tip part of this connection pipe part 6. As shown in FIG.

The air sucked together with the dust becomes suction wind, and the suction wind passes through the hose body 5 , passes through the suction port 14 and the ventilation port 33 , and then flows into the separation part 16 .

In addition, the suction wind is throttled (winded) by the separation main body part 17 to be accelerated, and among the dust contained in the suction wind, coarse dust with a larger specific gravity or size passes through the separation main body part 17 linearly together with the suction wind W1. And flow into the air passage 31 for coarse dust, the smaller fine dust of specific gravity or size is separated along the circumferential direction of the separation main body 17 and flows into the auxiliary opening 18, a part of the fine dust is caught by the mesh filter screen 18a, and at the same time, passes through The fine dust of the mesh filter 18a flows into the air passage 32 for fine dust together with the suction wind W2.

The coarse dust flowing into the air passage 31 for coarse dust is collected when the suction wind W1 flowing into the air passage 31 for coarse dust passes through the lower mesh filter 34 , and is accommodated in the air passage 31 for coarse dust. Furthermore, the suction wind W1 having collected the coarse dust passes through the pleated filter 38 , passes through the exhaust communication port 37 , flows from the exhaust port 15 into the communication air passage 19 , and flows to the suction side of the electric blower 3 .

On the other hand, the fine dust that has flowed into the air passage 32 for fine dust is collected by the pleated filter 38 when the suction wind W2 flows in the vertical direction and passes through the pleated filter 38 . Furthermore, the suction wind W2 which collected the fine dust flows into the communication air path 19 from the exhaust port 15 through the exhaust communication port 37 , and flows toward the suction side of the electric blower 3 .

Furthermore, the suction wind flowing into the electric blower 3 passes through the inside of the electric blower 3, becomes exhaust wind, and is discharged to the outside of the vacuum cleaner main body 2 through the exhaust hole.

In addition, after the cleaning is completed, the dust falling device 43 is driven by a motor not shown, and the fine dust collected by the pleated filter 38 falls from the pleated filter 38 and passes through the inclined plate 41 to accommodate into the dust container 42.

Furthermore, by detaching the dust collecting part 4 from the vacuum cleaner main body 2 under the state that the electric blower 3 is stopped, and operating the cover part buckle to open the opening and closing cover part 27, the air passage 31 for coarse dust and the fine dust storage part are respectively accommodated. The dust in the unit 42 is discarded to a dustbin (not shown) outside the dust collecting unit 4 or the like.

Thereafter, the dust collecting part 4 is mounted on the cleaner main body 2 again for use.

As described above, in the above-mentioned one embodiment, the coarse dust separated by the separation unit 16 passes through the coarse dust air passage 31 together with the suction wind W1, and the fine dust separated by the separation unit 16 passes through the remaining suction wind W2. The wind path 32 for the fine dust, on the dividing plate 26 between the wind path 31 for the coarse dust and the wind path 32 for the fine dust, forms a communication port 35 along the opening of the wind path 31 for the coarse dust, which is used to flow the coarse dust into the air path 32. The suction wind W1 of the air passage 31 for the dust is discharged from the air passage 31 for the coarse dust, and a lower mesh filter 34 is provided at the communicating port 35, which is used to prevent the dust collected by the air passage 31 for the coarse dust from Coarse dust escapes with wind path 31.

As a result, for example, compared with the case where the lower mesh filter is formed in a direction intersecting with the air passage 31 for coarse dust, it is not necessary to increase the cross-sectional area of the air passage 31 for coarse dust or the size of the cleaner main body 2, etc. Space can be saved, and the area of the lower mesh filter 34 can be easily ensured.

In particular, in the above-mentioned one embodiment, the separation part 16 has a substantially linear cylindrical separation body part 17 and an auxiliary opening 18 penetratingly provided around the separation body part 17. Straight-line (straight) separation can further reduce the size of the separation unit 16 and the electric vacuum cleaner 1 compared to, for example, a cyclone separation unit that swirls the suction wind to centrifugally separate dust.

In addition, since the air duct 31 for coarse dust has a dust collecting function for receiving passing dust, the cleaner main body 2 can be downsized compared with the case where a dust collecting part is provided separately from the air duct 31 for rough dust.

Furthermore, by making the air passages 31, 32 parallel in the vertical direction, and making the air passage 31 for coarse dust have a dust collecting function at the lower part, the dust flowing into the air passages 31, 32 falls by its own weight and easily stays in the main body part 25. The lower part makes it easy to separate the suction wind from the dust.

Furthermore, by setting the pleated filter screen 38 along the wind path 32 for fine dust at the position corresponding to the lower mesh filter screen 34, the air path resistance becomes larger because of these filter screens 34, 38, and the dust collection can be improved. While improving performance, it is also possible to make these filter screens 34, 38 difficult to be blocked.

In addition, by forming the pleated filter 38 in a pleated shape along the air passage 32 for fine dust, the surface area of the pleated filter 38 through which the suction wind W2 passes can be ensured, and the dust collection efficiency can be improved.

Furthermore, by placing the suction port 14 and the exhaust port 15 at positions opposite to the rear of the storage body part 25 of the dust collecting part 4 as the same side, when the dust collecting part 4 is attached to the cleaner body 2, only the The rear part of the dust collecting part 4 only needs to be provided with a packing. Therefore, for example, the sealing performance can be improved compared with the case where the packing is provided at both the front part and the rear part of the dust collecting part 4 .

Furthermore, by making the pleated filter screen 38 face to the front side and incline downward, at the same time, below the pleated filter screen 38, an inclined plate 41 continuous with the upper part of the dust storage part 42 is provided, so that when driving the falling dust When the device 43 is installed, the fine dust falling from the pleated filter 38 can be reliably accommodated in the fine dust storage portion 42 .

In addition, by applying the above-mentioned dust collecting part 4 to the upright electric vacuum cleaner, the shape of the cleaner body 1 that is long in the vertical direction can be effectively utilized, and the increase in size of the cleaner body 1 can be prevented.

In addition, in the above-mentioned one embodiment, as long as the separation unit 16 can separate dust according to specific gravity or size, it is not limited to the above-mentioned configuration.

Likewise, the details of the electric vacuum cleaner 1 are not limited to the above structure.

Furthermore, the electric vacuum cleaner 1 can be applied not only to a long-handled vacuum cleaner but also to a canister vacuum cleaner and the like.

The present invention is particularly suitable for, for example, an upright electric vacuum cleaner or the like.
