Dust that this is attracted and air are attracted to the suction connector 57a of collecting unit of dust 50 by prolonging pipe 14 and dust leg 12.Be attracted the dust and the air that so far suck connector 57a and pass through guiding wind path pipe 57, be fed in the separation chamber portion 54 of dust separation portion 52, and in this separation chamber portion 54, be rotated along the counter clockwise direction among Figure 23.

Then, the rotation of utilization in this separation chamber portion 54, and by act on the dust inertia force and and air separation, and air is by the well strainer NF1 (with reference to Figure 10) of dust separator 55 and the well strainer NF2 of opening 154B, by attracting wind path portion 56, be attracted in the storage box 81 of filter house 80 again.

On the other hand, separated dust utilizes inertia force,, is fed in the communication case portion 72 of dust collecting part 70 from the top of separation chamber portion 54 formed importing opening 53A with portion of air.

Dust that this is imported into and air are along the access 71 of the communication case portion 72 that is connected with importing opening 53A and roughly extends in horizontal direction, and roughly along continuous straight runs moves, and is attracted to dust storage chamber 73 by this access 71.

And, moving to the dust of the intake section of dust storage chamber 73, approximate vertical falls down, and puts aside in this dust storage chamber 73.

By this, even because of the dust amount of being put aside in dust collection case portion 74 increases, well strainer NF3 eyelet is stopped up, and air is inhaled in the dust separation portion 52 of dust separative element 400, drop to the dust of also putting aside in the dust storage chamber 73 and also can not be back in the dust separation portion 52, can positively put aside.

That is, even the dust that temporarily drops in the dust storage chamber 73 hikes up because of being inhaled into dust separation portion 52 interior air, also be difficult in the communication case portion 72 that along continuous straight runs extends, flatly move.Therefore, accumulate in the dust storage chamber 73 and can not be back in the dust separation portion 52.

By this, can prevent by the dust separation portion 52 of dust separative element 400 separatedly from air, and the dust of savings in dust collection case portion 74 refluxes.

In addition, be attracted to the opening 170A of the air of dust storage chamber 73, be attracted to attraction wind path portion 56, and then be attracted in the storage box 81 of filter house 80 by the bottom of well strainer NF3 and cover plate 170.

At this moment, the thin dirt that is carried in the air by well strainer NF3 is captured by well strainer NF3, and attached on this well strainer NF3.

Here, well strainer NF3 is by being capped by cover plate 170 on the position of setpoint distance that is separated by, and forms opening 170A in the bottom of cover plate 170, and makes the bottom of the well strainer NF3 more air that flows.Therefore, adhere to dust, stop up and produce eyelet from the downside of well strainer NF3.By this, can make dust begin to put aside from the downside of dust storage chamber 73 in order morely.

Be attracted to the air in the storage box 81,, be attracted to the connection wind path portion 25 of sweeper main body 11, be attracted to the suction opening 24A of electric blowing machine 24 then by the close pleat formula filter 104 of close pleat formula filtering bodies 100.

Be attracted to the air of the suction opening 24A of electric blowing machine 24, in electric blowing machine 24, be discharged from from the exhaust outlet 20H of sweeper main body 11 shown in Figure 2.

As clear away end, then the console switch 13a to operating portion 13A operates, and the driving of electric blowing machine 24 is stopped.After the driving that makes this electric blowing machine 24 stops, control device 200 drive motor M shown in Figure 21.Utilize the driving of motor M, driven wheel Ga is rotated and close pleat filtering bodies 100 is rotated.

Utilize the rotation of this close pleat filtering bodies 100, the projection 88 of the front wall portion 84 of storage box 81 contacts with the protuberance 104Ab of the protuberance 104A of close pleat formula filter 104, when to 104 pairs of close pleat formula filters during with vibration, accompanying dust is shaken on close pleat formula filter 104.This dust is put aside on the dust carrier 86 of storage box 81.

Projection 88 is owing to be arranged on the downside of the pivot of close pleat formula filtering bodies 100, so can pay big vibration to the close pleat formula filter 104 of the lower portion of close pleat formula filtering bodies 100.Therefore, when dust from then on the close pleat formula filter 104 of lower portion shaken and when intactly falling, can therefore can dust be fallen efficient once more attached on the close pleat formula filter 104 in the way of its whereabouts to dust carrier 86.

On the other hand, when scanning out body 300 and be rotated with close pleat formula filtering bodies 100, the 1st sliding contacting part 303A that scans out member 303 that scans out body 300 moves in the enterprising line slip contact of the inner peripheral surface of the dust carrier 86 of storage box 81.Utilize this sliding-contact to move, the dust that is accumulated on dust carrier 86 has been swept, and along upwards being released on the side face of dust carrier 86, then, when scanning out member 303 and come on the position of outlet opening 84K, outlet opening 84K is opened (with reference to Figure 22), and this dust that is pushed out is discharged to outlet opening 84K, and turns back to by communication member 403 in the separation chamber portion 54 of dust separation portion 52.

Then, when close pleat filtering bodies 100 is carried out for example 1 rotation, when scanning out member 300 and coming on the position of Figure 16, microswitch S1 is converted to the detection of minor diameter part 110A from the detection of the large-diameter portion 110B of the cylindrical portion 110 of close pleat filtering bodies 100, the driving of motor M is stopped, and the rotation of close pleat filtering bodies 100 is stopped.Then, outlet opening 84K covers 450 obturations by obturation as described above.

And under the situation of when scanning out the scanning out member 303 and open outlet opening 84K of body 300 attaching plug being extracted from socket, the driving of motor M stops, and outlet opening 84K stays open.

But, as described above, this electric dust collector 10 is when being connected attaching plug on the socket, drive motor M and close pleat formula filtering bodies 100 is rotated, then after scanning out member 303 and coming on the position shown in Figure 16, the driving of motor M is stopped and making to scan out on the position that member 303 stops at Figure 16.

Therefore, can make outlet opening 84K cover 450 obturations, electric blowing machine 24 is driven, so can prevent to be back to the unsuitable problem that the dust of the separation chamber portion 54 of dust separation portion 52 is attracted from outlet opening 84K by obturation.

In addition, accumulating in the rotation that dust utilization on the dust carrier 86 scans out member 303 moves, and turn back to by communication member 403 in the separation chamber portion 54 of dust separation portion 52, so not be used in the dust collecting part of the special use that close pleat formula filter 104 usefulness are set in the dust collecting part unit 410 from outlet opening 84K.

When in close pleat formula filtering bodies 104, producing the eyelet obstruction owing to long-standing use, dust separative element 400 is pulled down from sweeper main body 11, close pleat formula filter 104 is cleaned.

The dismounting of dust separative element 400, at first be after pulling down dust collecting part unit 410, to carry out from main body box 20, but by setting so that driven wheel Ga becomes lower position from the pivot position of the gear 107 of close pleat formula filtering bodies 100, and make driven wheel Ga can not form obstruction, only need dust separative element 400 is upwards lifted, the gear 107 that can make close pleat formula filtering bodies 100 Ga from the driven wheel breaks away from.Therefore, dust separative element 400 can be removed from the collecting unit of dust chamber 22 of sweeper main body 11 simply.

And, as also when the installation of dust separative element 400, with this dust separative element 400 insertion above collecting unit of dust chamber 22, then driven wheel Ga can not form obstruction, can make the gear 107 of close pleat formula filtering bodies 100 carry out interlock, and dust separative element 400 is installed in the collecting unit of dust chamber 22 like a cork with driven wheel Ga.

More than, at length be illustrated illustrating, but concrete formation is not limited to above-mentioned example about an example utilization of the present invention.The change etc. of design that does not break away from the scope of main idea of the present invention is also contained among the present invention.

For example, in above-mentioned example, be that the dust of being discharged from outlet opening 84K is returned in the separation chamber portion 54 of dust separation portion 52, but be not limited thereto, for example also can return guiding wind path pipe 57 as the upstream of dust separation portion 52.

And, in the above-described embodiments, be by close pleat formula filtering bodies 100 is rotated, accompanying dust falls on the close pleat formula filtering bodies 104 and make, but is not limited thereto, and close pleat formula filtering bodies 100 is rotated, and close pleat formula filtering bodies 104 is paid vibration, dust is fallen.
