And then, the suction wind being blowed on this main filter 106 is peelled off the dust being attached on main filter 106, and in thick dust arrestment chamber 91 interior to arrow A direction, from rear portion downside after anterior upside curls up, while by main filter 106 trap debris, to filter installation portion 92, flow.By this, curl up, by the thick dust that is included in the block rubbish that sucks in wind etc. by centrifugal force centrifugation (cyclonic separation), on one side towards the compression of the below of front wall portion 104, accumulate on one side.
In addition a part that, sucks wind is at the dust that is captured when communication chamber 93 flows by sidepiece filter 102 and ventilation filter 116.
Suction wind by main filter 106 or communication chamber 93 (sidepiece filter 102 and breather filter 116), when by pleated filter 123, will be not trapped by the fine dust of these filters 102,106,116 trappings.
Then, by sucking the connected entrance of wind via next door 26, to electric blower 27, suck, by this electric blower 27, become exhaust wind, the outside by the exhaust outlet from main body casing 25 to main body of dust collector 13 dumps.
When finishing cleaning, operator operates predetermined setting button 22 and electric blower 27 is stopped.By stopping of this electric blower 27, by each shutter 113 under Gravitative Loads forwards downside rotate, peristome 112 is opened.Under this state, dust is shaken off the 125 action scheduled times of portion, the fine dust being captured on pleated filter 123 is shaken off to remove, via 94 trappings of peristome 112Xiang fine dust dust trapping chamber.In addition, dust shake off portion 125 also can be such as making electric blower 27 wait also action before will starting.
Then, operator's operating line batches button 79, and the power line taking off from socket 31 is batched to spool from line export mouth 77.
In addition; in the situation that be captured in more than dust on dust pocket 36 accumulated scheduled volume; operator opens the lid of main body of dust collector 13 43; dust pocket 36 is pulled down from main body dust storage chamber 35; by controlled opening/closing action button 96 above dustbin etc.; bowl cover 87 is opened, and dumps mouth 95 fine dust that is captured in the thick dust thick dust arrestment chamber 91 and be captured in fine dust dust trapping chamber 94 is dumped from dust.
And then, in the situation that the meshes such as sidepiece filter 102 and breather filter 116 stop up, by being abandoned to mouth 95 from dust, raising middle flask 86 pulls out downwards, from cup main body 85, pull down, carry out the maintenance of each filter 102,116.Now, although mesh can occur main filter 106 hardly, stop up, if in the situation that waiting generation mesh to stop up because of lasting long-term use continuously, dust is removed.
Then, operator is being arranged on raising middle flask 86 under the state on glass main part 85 bowl cover 87 is being closed, and dust pocket 36 is installed to again in the main body dust storage chamber 35 of main body of dust collector 13, and lid 43 is closed.
As mentioned above, in an above-mentioned embodiment, made by helical spring 65 more free to advance or retreat and can contact trailing wheel 52 on the ground under state out with respect to ground F by rear than wheel 51 the rotating shaft 57 that travels, towards ground F to the structure of the direction application of force out.
Therefore, in the situation that such as trailing wheel etc. is located on main body casing with the state of giving prominence to, although can improve the straightaway of main body of dust collector 13, but this trailing wheel etc. becomes resistance and rotatory declines when the rotation of main body of dust collector 13, with respect to this, according to an above-mentioned embodiment, because trailing wheel 52 flexibly contacts on the F of ground, so trailing wheel 52 contacts with suitable contact with respect to ground F by suitable advance and retreat, the rotatory of taking turns 51 main body of dust collector that bring 13 so can not make to travel declines and improves straightawaies with the situation phase specific energys of only travelling by the wheel 51 that travels.
And, because trailing wheel 52 is only provided with 1 on the center of the left and right of main body of dust collector 13 width, thus can be when guaranteeing the balance of straightaway, will be suppressed at Min. with the frictional resistance of ground F, and can guarantee rotatory.
In addition, trailing wheel 52, owing to always flexibly contacting on the F of this ground under the transport condition of the main body of dust collector 13 of wheel 51 ground connection on the F of ground that makes to travel, so trailing wheel 52 can not float from ground F, can improve straightaway reliably.
And then, trailing wheel 52 by rear wheel body 62 axles are supported to the place ahead of rear wheel body 62 and make this rear wheel body 62 with respect to the direction of ground F advance and retreat on the rotatable earth's axis be bearing on the axle support 61 on main body casing 25, when the advancing of main body of dust collector 13, be positioned at than rear wheel body and compare by the situation of rear side with the turning cylinder that for example makes axle support, it is upper that axle support 61 is more difficult for being stuck in ground F, and trailing wheel 52 becomes and more easily rotates.
And, because axle support 61 is bearing in than the line that the travel rotating shaft 57 of wheel 51 and the rotating shaft of rear wheel body 62 are linked on the lower by axle in side view, so axle support 61 diminishes with respect to the angle of inclination of ground F, rear wheel body 62 is suppressed with the contact resistance of ground F, and trailing wheel 52 becomes and more easily rotates.
In addition, by front-wheel 53 rotation is located at freely the ratio of main body casing 25 travel wheel 51 rotating shaft 57 on the front, in the situation that there is the ladder D of barrier etc. during the advancing of main body of dust collector 13, by front-wheel 53, meeting this ladder D above rotates, easily cross over ladder D etc., cleaning work improves.
And then, by travel the wheel portion 56 of wheel 51 contact on the F of ground by soft synthetic resin forms, trailing wheel 52 possesses the flannelette of scraping 67 on the outer peripheral face that contacts the rear wheel body 62 on the F of ground, the wheel 51 that travels is also difficult for sliding with respect to more smooth ground F, and trailing wheel 52 easily slides with respect to ground F, so when guaranteeing straightaway by trailing wheel 52, trailing wheel 52 is difficult for becoming resistance when rotated, can improve rotatory.
And, by arranging in the periphery of the rear wheel body 62 at trailing wheel 52, scrape flannelette 67, in the periphery of the front wheel body 72 of front-wheel 53, to arrange and scrape flannelette 76, can scrape the dust that flannelette 67,76 picks up ground F by these.
In addition, in an above-mentioned embodiment, trailing wheel 52 and front-wheel 53 also can arrange respectively a plurality of.In the case, preferably along left and right width approximate equality, i.e. configuration symmetrically on the width of left and right, to can stably support main body of dust collector 13.
In addition as long as can cross over the ladder D on the F of ground, can be also the structure that front-wheel 53 is not set.
And then, as dust collect plant, used the dust pocket 36 of centrifugation, but such as being the structure by controls of dust such as paper bags or carrying out structure of control of dust etc. by straightaway separation, dust collect plant can at random be selected.Thereby the internal structure of main body of dust collector 13 etc. is not defined to said structure.
The inventive example if suitably used in the moving dust catcher of household electricity etc.
