The air is sucked into the suction side of the electric blower 3 from the mouth.

  If the bag 31 is not attached to the partition wall 26, the coarse dust that has flowed into the coarse dust collection air passage 29 when the suction air passes from the intake port 43 to the entire opening 27 is collected. Fine dust is collected by the filter 28 when the suction air collected in the dust air passage 29 passes through the opening 27 and passes through the pleat filter 46. After the dust is collected, the dust is sucked from the exhaust port to the suction side of the electric blower 3.

  On the other hand, the fine dust flowing into the fine dust collecting air passage 25 is collected by the pleated filter 46 when passing through the pleated filter 46 along the vertical direction. Then, the suction air in which the fine dust is collected is sucked from the exhaust port to the suction side of the electric blower 3.

  Then, the suction air sucked into the electric blower 3 passes through the electric blower 3 to become exhaust air, and is exhausted from the exhaust hole to the outside of the cleaner body 2.

  Furthermore, when the bag 31 is attached and cleaned, the operator removes the dust collecting cup 4 from the cleaner body 2 with the electric blower 3 stopped, and as shown in FIG. The cup opening / closing lid 22 is opened while the bag 31 is attached to the cleaner body 2 side, and the upper side of the accommodating portion clamp 38 is pushed to rotate the accommodating portion clamp 38 to the front side to thereby engage the engaging portion 38a and the claw The engagement with the portion 63a is released, and the bag housing portion 32 is rotated downward about the hinge portion 65.

  Then, the handle portion 62c is slid vertically to bring the brush member 62f into sliding contact with the surface of the filter 28 and dropped into the bag body 31 collected by the filter 28, and then the bag body 31 together with the pressing member 53. Is removed from the partition wall 26, the partition wall member 55 and the clamping member 56 are removed, the bag body 31 is removed from the pressing member 53, and the dust D accommodated in the bag body 31 is discarded together with the bag body 31 in a trash box or the like. .

  Thereafter, the operator pulls out the bag body 31 pulled out from the slit 66 again, and attaches the opening 31a of the bag body 31 to the partition wall 26 together with the pressing member 53.

  When the bag body 31 stored in the bag body storage portion 32 is exhausted, the knob 67 of the lid portion 64 is picked while the bag body storage portion 32 is rotated downward, and this is removed from the storage portion main body 63. The lid portion 64 is removed, the folded bag body 31 is replenished into the housing portion main body 63, and the lid portion 64 is closed.

  When cleaning is performed without attaching the bag 31, the operator removes the dust cup 4 from the dust cup fitting recess 14 of the vacuum cleaner body 2 and operates the lid clamp 36 on the trash can. Then, the cup opening / closing lid 22 is opened and the dust D accumulated in the dust collecting air passage 29 for coarse dust is discarded.

  The operator closes the cup opening / closing lid 22 and then attaches the dust collecting cup 4 to the dust collecting cup fitting recess 14 of the cleaner body 2 again.

  As described above, according to the above-described embodiment, the opening of the bag body 31 is formed in the intake port 43 of the dust collecting air passage 29 for coarse dust that communicates with the separation unit 24 and the opening 27 that is opened in the partition wall 26. 31a is connected in an airtight manner so that the bag body 31 can be accommodated in the dust collection air passage 29 for coarse dust. 31a is connected to the air inlet 43 and the opening 27 in an airtight manner and can prevent a pressure difference between the inside and outside of the bag 31.For example, a general bag that is not a dedicated dust collection pack having air permeability is used. Since it can be used, the cost during use can be reduced compared with the case where a dedicated dust collection pack is used, and it is not necessary to keep a dust collection pack or the like.

  In addition, when the bag 31 is attached to the partition wall 26, the coarse dust that has flowed into the dust collecting air passage 29 for coarse dust is collected in the bag 31 to prevent dirt in the dust collecting air passage 29 for coarse dust. In addition, since the collected dust can be discarded together with the bag body 31, it is also possible to prevent the dust from scattering during the disposal.

  Further, even when the bag 31 is attached to the partition wall 26 and is not accommodated in the coarse dust collection air passage 29, coarse dust can be collected by the coarse dust collection air passage 29 and the fine dust collection air passage 25. Can collect fine dust.

  As a result, according to the one embodiment, the usability of the electric vacuum cleaner 1 is improved.

  In addition, the clogging of the filter 28 can be surely prevented by providing the dust dropping member 62 that can remove the dust collected by the filter 28.

  Furthermore, by holding the dust drop member 62 with the pressing member 53 that allows the bag body 31 to be attached to and detached from the partition wall 26, for example, the number of parts can be reduced compared to a case where a member for holding the dust drop member is provided separately. Further, the dust of the filter 28 removed by the dust removing member 62 can be easily collected in the bag 31 and can be prevented from scattering in the dust collecting air passage 29 for coarse dust.

  In addition, by arranging the dust drop member 62 in the coarse dust containing air passage 29 that is outside the bag body 31, the dust drop member 62 is not contaminated with dust. Thus, the operator can clean the filter 28 without getting his hands dirty, and it becomes hygienic.For example, a part of the dust drop member is led out of the dust collecting cup to collect dust without getting his hands dirty. Compared with the case where it can be operated from the outside of the cup, leakage of air from the dust collection cup 4 to the outside, that is, leakage can be suppressed, and the mechanism of the dust drop member 62 can be simplified.

  Further, by making the dust collecting cup 4 detachable from the cleaner body 2, it becomes easy to attach and detach the bag 31 or to dispose of dust, and the usability is further improved.

  Further, by providing the dust collecting cup 4 with a bag housing portion 32 for housing the bag body 31, when the bag body 31 is replaced, the bag body 31 is searched again, or the bag body 31 is placed at the place where the bag body 31 is placed. Saves time and effort and improves usability.
