  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments.

(Embodiment 1)
The dust collector in the 1st Embodiment of this invention is demonstrated using FIGS.

  FIG. 1 is an overall perspective view of a vacuum cleaner equipped with a dust collector in the present embodiment, FIG. 2 is a perspective view of the dust collector, a perspective view with a cover and a lid open, and FIG. Fig. 4 is a front sectional view of the dust collector at the central axis of the upstream filter, Fig. 4 is a sectional view showing the flow of wind in the dust collector, and Fig. 5 is an extension of the upstream filter of the dust collector. It is sectional drawing in the center axis | shaft which showed a mode that dust stayed in the exit part, and the flow of the wind.

  In FIG. 1, a vacuum cleaner equipped with a dust collector in the present embodiment includes a cleaner body 1, a hose 2 connected to a suction port 1 a provided in front of the cleaner body 1, and a tip of the hose 2. A suction pipe 5 having an opening (not shown) that is connected to the distal end of the extension pipe 4 and sucks dust. The vacuum cleaner main body 1 includes an electric blower 6 for sucking dust and a dust collecting device 7 for collecting dust.

2-5, when the dust collector 7 in this Embodiment divides roughly into components, the dust collection case 8 which comprises an outer shell, and the cover 9 comprised so that the upper surface of the dust collection case 8 might be plugged up, The cover 9 includes an upstream filter 12, a downstream filter 10 provided to close the rear portion of the dust collection case 8, and a lid 11 configured to close the lower surface of the dust collection case 8. .

  The upstream filter 12 is integrally formed with the cover 9 or attached to the cover 9 by fitting unevenness. The cover 9 includes a bijou 14 and a bijou 15, and an engaging portion 16 provided on the downstream filter 10 and dust collecting. It is fixed by being fitted to the engaging portion side 18 provided in the case 8.

  Further, the cover 9 and the dust collecting case 8 are configured to be airtight with a packing B20 and a packing C30 shown in FIG. The lid 11 is provided with a packing A19 and is rotatable about a shaft 13 provided on the lid 11. The lid 11 can be fixed to the dust collection case 8 by a stopper 17 and can be airtight with the dust collection case 8 by packing A19. Reference numeral 21 denotes a handle that is gripped when the dust collection case 8 is taken out from the cleaner body 1 or when the dust collection case 8 is carried.

  As shown in FIG. 3, the upstream filter 12 includes an exhaust tube 22 and an extending portion 23 having a plurality of through holes 25 on the outer peripheral side surface. The exhaust tube 22 and the extending portion 23 are separated by a partition surface 31. ing. Further, with the partition surface 31 as a boundary, the upper portion is a separation chamber 42 and the lower portion is a dust collection chamber 41. Further, the outer peripheral side surface of the extending portion 23 extends in the vertical direction with respect to the bottom surface of the dust collection chamber 41. Further, the outer peripheral side surface of the extending portion 23 extends in a direction perpendicular to the bottom surface of the dust collecting chamber 41, and a predetermined interval is provided between the extending portion 23 and the inner wall and bottom surface of the dust collecting chamber 41. A gap is provided.

  The downstream filter 10 is fixed to the dust collecting case 8 by fitting between the vision way 14 and the locking portion 16 and fixing the filter shaft 28 and the bearing portion 32 provided in the dust collecting case 8. As shown in FIG. 4, the air containing dust flowing in from the air inlet 26 by the electric blower 6 provided behind the downstream filter 10 is guided to the exhaust tube 22 side by the wall surface 39, and the induced dust is removed. The contained air is introduced into the separation chamber 42 from the tangential direction of the exhaust tube 22. The introduced air containing the dust is separated in the separation chamber 42 by the exhaust tube 22, and the dust is centrifuged and accumulated in the dust collection chamber 41.

  The dust accumulated in the dust collection chamber 41 is removed by removing the stopper 17 provided on the lid 11, so that the lid 11 rotates about 90 degrees around the hinge portion 13 as a rotation axis, and the dust in the dust collection chamber 41 is discarded. be able to. On the other hand, the air passes through the upstream filter 12, passes through the intake passage B 38 and the intake passage A 37, and passes through the pleated filter 29 disposed in the downstream filter 10. Dust that has not been centrifuged in the separation chamber 42 and has passed through the intake passage B 38 and the intake passage A 37 is collected by the pleated filter 29.

  The dust collected by the pleated filter 29 is peeled off from the pleated filter 29 due to the vibration generated by moving the jog lever 33 disposed in the downstream filter 10 on the rail-shaped holder 34 that fixes the jog lever 33. The dust is stored in the dust chamber 35. The holder 34 is fixed to the downstream filter 10 with screws.

  As shown in FIG. 5, the dust 36 accumulated in the dust collecting chamber 41 tends to fly to the separation chamber 42 side by the air flow. The air that is about to flow up flows from the inside to the outside of the extending portion 23 through the through-hole 25 provided on the side surface of the extending portion 23, so that the dust 36 that has risen by the air flow enters the extending portion 23. Therefore, it is possible to prevent problems such as clogging around the exhaust tube 22 and a reduction in suction force.

Further, the dust 24 that is about to fly up can be retained in the extension portion 23 by the flange 24 disposed on the bottom surface of the extension portion 23, and performance degradation due to return can be prevented.

  In addition, as shown in FIG. 6, if the diameter of the extension part 23 is made larger than the diameter of the exhaust pipe 22, more dust can be kept in the extension part 23, and the performance deterioration due to the return is further reduced. It can be surely prevented.

  Further, as shown in FIG. 7, the extension portion 23 is provided with a screw portion 27 that is screw-fitted to a female screw (not shown) provided on the exhaust tube 22, and the extension portion 23 is detachably attached to the exhaust tube 22. If it can fix to, it can remove and wash | clean only the extension part 23, and can always keep clean.

  Moreover, it goes without saying that an easy-to-use vacuum cleaner can be provided by mounting the dust collector 7 in the above embodiment on the cleaner body 1.

  As described above, the dust collector according to the present invention causes dust such as cotton dust accumulated in the accumulation chamber to enter the extension portion by the flow of air from the inside to the outside through the through hole provided in the extension portion. It can be fastened and prevented from rising, and can be applied to various vacuum cleaners.
