And the spatial portion that fine dust that portion 125 removes from pleated filter 123 is accumulated via peristome 112 will be shaken off by fine dust dust trapping chamber 94 by dust.
The action of an above-mentioned embodiment then, is described.
When cleaning, at first, the operator opens the lid 43 of main body of dust collector 13, and dust pocket 36 is installed in the main body dust storage chamber 35, and lid 43 is closed.At this moment, the operator is connected to hose body 16 on the main body suction inlet 83 of upside via tube connector portion 15, is connected to the front of this hose body 16 successively with prolonging pipe 18 and floor cleaner brush 19.
And then the operator pulls out power line 31 from main body of dust collector 13, is connected on the not shown socket.
Then, if the operator controls handle part 21 and the predetermined setting button 22 of operation, then drive electric blower 27 according to the pattern of setting by this setting button 22.Driving by this electric blower 27, each shutter 113 is adsorbed on the front face side of inclined wall portion 111 by the air that has passed through vent openings 107 (lower filter 108), peristome 112 is closed, and the fine dust that become trapped in the fine dust dust trapping chamber 94 can be sucked into filter installation portion 92 (pleated filter 123) side from peristome 112.
Then, while the operator makes main body of dust collector 13 floor cleaner brush 19 be travelled travelling on the F of ground along front and back by controlling handle part 21, dust is sucked with the front of air from floor cleaner brush 19 by the negative pressure of electric blower 27.
At this moment, main body of dust collector 13 by by helical spring 65 application of forces so that the axle support 61 rear side rotate downwards, trailing wheel 52 from nowel 41 earthward the F side come out, become the state of flannelette 67 contacts on the F of ground of scraping of back wheel body 62,51 carry out support, stably straight-line travellings at 3 by this trailing wheel 52 and two wheel that travels.Back wheel body 62 in Elastic Contact under the effect of helical spring 65 on the F of ground, so the vibration of the above-below direction that takes place when the travelling of main body of dust collector 13 is flexible along with this vibration etc. by helical spring 65, trailing wheel 52 is advanced and retreat in the installation portion 63 of main body casing 25 and is absorbed, back wheel body 62 contacts on the F of ground with suitable contact pressure.And then, if when in the travelling of main body of dust collector 13, wanting the ladder D of across obstacle etc., then the preceding wheel body 72 by front-wheel 53 contacts on this ladder D, cross this ladder D easily, and the rear side of the axle support 61 by trailing wheel 52 overcomes the application of force of helical spring 65 and turn to the top above this ladder D etc., prevents that thus trailing wheel 52 (back wheel body 62) is stuck on the ladder D.
In addition, when the operator with pipe portion 12 with respect to main body of dust collector 13 during along horizontal tractive etc., by one travel wheel 51 forwards, another wheel 51 rotation respectively rearward of travelling, main body of dust collector 13 rotations are to follow the direction of draw of pipe portion 12.
Become suction wind from floor cleaner brush 19 with the dust inhaled air, dust is transported to dust pocket 36 from main body suction inlet 83 via prolonging pipe 18 and hose body 16 (tube connector portion 15).
In this dust pocket 36, the suction wind that will suck to air entry 97 from main body suction inlet 83 via aspiration column portion 98 and be communicated with tube portion 103 along the opening direction of air entry 97 with linearity roughly to 91 suctions of thick dust arrestment chamber,, will often peel off with skewed direct winding-up to the upstream side of main filter 106 attached to the dust on this main filter 106.
And then, the suction wind that is blowed on this main filter 106 will be peelled off attached to the dust on the main filter 106, and in thick dust arrestment chamber 91 to the arrow A direction, promptly from the rear portion downside after anterior upside curls up, while flow to filter installation portion 92 by main filter 106 trap debris.Curl up by this, with the thick dust that is included in the block rubbish that sucks in the wind etc. by centrifugal force centrifugation (rotational flow separation), on one side accumulate on one side towards the compression of the below of front wall portion 104.
In addition, suck the part of wind at the dust that when communication chamber 93 flows, is captured 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) by pleated filter 123 time, the fine dust capture that will not capture by these filters 102,106,116.
Then, suck to electric blower 27, become exhaust wind, dumped to the outside of main body of dust collector 13 by exhaust outlet from main body casing 25 by this electric blower 27 with sucking the connected entrance of wind via next door 26.
When finishing cleaning, the operator operates predetermined setting button 22 and electric blower 27 is stopped.By stopping of this electric blower 27, by the downside rotation forwards under the deadweight effect of each shutter 113, peristome 112 is opened.Under this state, dust is shaken off the 125 action scheduled times of portion, and the fine dust that is captured on the pleated filter 123 is shaken off to remove, and captures to fine dust dust trapping chamber 94 via peristome 112.In addition, dust is shaken off portion 125 and also can be is for example made electric blower 27 wait also action before will starting.
Then, operator's operating line batches button 79, and the power line 31 that will take off from socket batches to spool from line export mouth 77.
In addition; accumulated under the situation more than the scheduled volume at the dust that is captured on the dust pocket 36; the operator opens the lid 43 of main body of dust collector 13; 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 mouthfuls 95 from dust and will be captured in the thick dust the thick dust arrestment chamber 91 and the fine dust that is captured in the fine dust dust trapping chamber 94 dumps.
And then, under the situation that meshes such as sidepiece filter 102 and breather filter 116 stop up,, raising middle flask 86 pulls out downwards by being abandoned mouth 95 from dust, pull down from cup main body 85, carry out the maintenance of each filter 102,116.At this moment, stop up, if, dust is removed waiting under the situation that the mesh obstruction takes place because of continuing for a long time use continuously though mesh can take place main filter 106 hardly.
Then, the operator closes bowl cover 87 under the state that raising middle flask 86 is installed on glass main part 85, dust pocket 36 is installed to once more 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 and will under and the state that coming out more free to advance or retreat by the rear, can contact on the ground trailing wheel 52, towards the structure of ground F to the direction application of force of coming out with respect to ground F than wheel 51 the rotating shaft 57 that travels.
Therefore, trailing wheel etc. is located at outstanding state under the situation on the main body casing, though can improve the straightaway of main body of dust collector 13, but this trailing wheel etc. becomes resistance and rotatory descends 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 by suitable advance and retreat and with respect to ground F with suitable contact pressure contact, so the rotatory of wheel 51 main body of dust collector that bring 13 that travel is descended with only by travel wheel 51 situations of travelling mutually specific energy improve straightaway.
And, because trailing wheel 52 only is provided with 1 on the center of the left and right sides 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 is owing in that wheel 51 ground connection of travelling are always flexibly being contacted on the F of this ground under the transport condition of the main body of dust collector on the F of ground 13, so trailing wheel 52 can not float from ground F, can improve straightaway reliably.
And then, trailing wheel 52 by will 62 of the wheel bodies in back support to the place ahead of back wheel body 62 and make this back wheel body 62 with respect to the direction of ground F advance and retreat on the rotatable earth's axis be bearing on the support 61 on the main body casing 25, when the advancing of main body of dust collector 13, be positioned at than back wheel body with the turning cylinder that for example makes a support and compare by the situation of rear side, axle support 61 more is difficult for being stuck on the F of ground, the trailing wheel 52 easier rotation that becomes.
And, because axle support 61 is bearing in below line that the rotating shaft than will travel wheel 51 rotating shaft 57 and back wheel body 62 links leans on by axle in side view, so axle support 61 diminishes with respect to the angle of inclination of ground F, back wheel body 62 is suppressed with the contact resistance of ground F, the trailing wheel 52 easier rotation that becomes.
In addition, by the ratio that front-wheel 53 rotation is located at freely main body casing 25 travel wheel 51 rotating shaft 57 on the front, when the advancing of main body of dust collector 13, have under the situation of ladder D of barrier etc., meeting this ladder D by front-wheel 53 upward rotates, cross over ladder D etc., cleaning work raising easily.
And then, contact by the wheel 51 that travels is formed by soft synthetic resin in the wheel portion 56 on the F of ground, trailing wheel 52 possesses the flannelette of scraping 67 in contact on the outer peripheral face of the back wheel body 62 on the F of ground, travel wheel 51 with respect to also being difficult for sliding than flat ground surface F, and trailing wheel 52 slides easily 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,, can scrape the dust that flannelette 67,76 picks up ground F by these by scraping flannelette 76 being provided with on the periphery of the back wheel body 62 of trailing wheel 52 to scrape to be provided with on flannelette 67, the periphery at the preceding wheel body 72 of front-wheel 53.
In addition, in an above-mentioned embodiment, trailing wheel 52 and front-wheel 53 also can be provided with a plurality of respectively.In the case, preferably along left and right sides width approximate equality, i.e. configuration symmetrically on the width of the left and right sides, so that can stably support main body of dust collector 13.
In addition, as long as can cross over ladder D on the F of ground, also can be the structure that front-wheel 53 is not set.
And then, having used the dust pocket 36 of centrifugation as dust collect plant, but for example be the structure by controls of dust such as paper bags or separate to come structure of control of dust etc. by straightaway, 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.
