Abstract
The invention provides an electric dust collector capable of preventing suction force from reducing and meanwhile increasing the use convenience, in a structure capable of preventing dust on a floor from being raised. A spray port (19) capable of obliquely spraying air flow upwards is formed on a frame of an electric dust collector (1) below an exhaust port (10). The air flow collides with an exhaust flow from the exhaust port (10) to make the air from the frame (4) flowing upwards to apart from the floor surface (X), so as to prevent the dust on the floor from raising due to exhaust. Because the exhaust port (10) is always opened, the air is smoothly exhausted from the exhaust port (10) to prevent the suction force from being reduced. If an electric blower (5) is driven, the air flow automatically sprays from the spray port (19) to collide with the exhaust flow from the exhaust port (10), thus the dust on the floor is cushily prevented from being raised.

The specific embodiment
Below, with reference to accompanying drawing embodiments of the present invention are described particularly.
Fig. 1 (a) is the right side view of the electric dust collector 1 of one embodiment of the present invention, (b) is the major part right side cross-sectional view of (a).Fig. 2 is the rearview of electric dust collector 1.Below, about the explanation of electric dust collector 1 and structure member thereof, short of explanation especially in advance, for convenience, with the left side among Fig. 1 (a) as the front side, with the right side as rear side, with the front side as the right side, the inboard is described as the left side.In addition, left and right directions is identical with width.
Shown in Fig. 1 (a), electric dust collector 1 possesses main body of dust collector 2 and flexible pipe 3, though not shown, possess at the front end of flexible pipe 3 and to be used to make electric dust collector 1 work and operating portion, pipe arrangement and the suction tool of operation.
In Fig. 1 (a), before and after forming, main body of dust collector 2 grows and is with the box shape of fillet slightly.Main body of dust collector 2 mainly possesses the ducted body that forms its exterior contour and is framework 4, electric blower 5 (having applied the part of the hatching that is made of the oblique line that extends to the upper right side among Fig. 5 described later), is used for the electric wire 6 (with reference to Fig. 2) to electric blower 5 supply capabilities.
On framework 4, be formed with air entry 8 at front surface 7,9 are formed with exhaust outlet 10 in the rear surface, and the air flow circuit 11 (also with reference to Fig. 5) that is communicated with air entry 8 and exhaust outlet 10 is arranged in framework 4 internal separation.Above-mentioned electric blower 5 is configured in the air flow circuit 11 (with reference to Fig. 5).
One end of flexible pipe 3 is connected with air entry 8, and the inside of flexible pipe 3 and air flow circuit 11 are interconnected.
And, be used to make main body of dust collector 2 to separate and the handle 13 that moves rotates the rearward end of the end face 12 that is arranged on framework 4 freely from floor X, the rearward end of the side 14 about wheel 15 is arranged on, Caster 17 is arranged on the front part of bottom surface 16.Wheel 15 and Caster 17 rotate on floor X, and thus, main body of dust collector 2 moves on floor X smoothly.
At this, shown in Fig. 1 (a), when main body of dust collector 2 is in common attitude, promptly the bottom surface 16 of framework 4 from above with floor X under opposed and wheel 15 and Caster 17 and the floor X state of contact, rear surface 9 is general planar vertically.In rear surface 9, be formed with above-mentioned exhaust outlet 10 and conduit outlet 18 (also with reference to Fig. 2) at upper portion, be formed with ejiction opening 19 (also with reference to Fig. 1 (b)) in lower portion (that is the below of exhaust outlet 10 and conduit outlet 18).
As shown in Figure 2, exhaust outlet 10 for example is 9 to be formed with a plurality of apertures in the rear surface, and is whole for being the roughly semi-circular shape that bloats to upside.
Be provided with the tabular air door 22 that is elongated on width at ejiction opening 19.Axle 37 (with reference to Fig. 1 (a)) that air door 22 extends with broad ways are that rotate at the center, thereby open and close freely.In Fig. 1 (b), air door 22 is to close along the mode on first inclined plane 20, with the inboard obturation of ejiction opening 19 from framework 4.
In such electric dust collector 1, when cleaning, the electric wire 6 (with reference to Fig. 2) that electric blower 5 (with reference to Fig. 5) links to each other with socket (not shown) from plug 23 receives outside electric power and is driven, and produces attraction thus.Under the effect of this attraction, dust on the floor X shown in Fig. 1 (a) is inhaled in the above-mentioned suction tool (not shown), by behind suction tool, pipe arrangement (not shown), the flexible pipe 3, sucked the air flow circuit 11 of main body of dust collector 2 from air entry 8 in order.In addition, suction tool (not shown) ambient air also the dust on floor X be inhaled in the air flow circuit 11.
At this, in air flow circuit 11, be provided with filter 24 (having applied the part of the hatching that is made of the oblique line that extends to the lower right among Fig. 5) in the front of electric blower 5 (upstream side of the flow direction of air in the air flow circuit 11), the air that is drawn into air flow circuit 11 separates in filter 24 with dust.And dust lodges in filter 24, and on the other hand, air is in the downstream of the electric blower on the flow direction of above-mentioned air 5 ejection in air flow circuit 11 under the effect of electric blower 5.Major part is discharged outside equipment from exhaust outlet 10 in the air of ejection, and a part is sprayed onto the electric wire 6 that is positioned at framework 4, discharges outside equipment from conduit outlet 18 afterwards.When under the state of not drawing electric wire 6 fully, using electric dust collector 1, electric wire 6 may be overheated, the part of the exhaust of electric blower 5 is discharged and cooling electric wire 6 to above-mentioned wire spool (not shown) side, and this cooling air is discharged outside equipment from conduit outlet 18 afterwards.
In addition, in Fig. 1, air door 22 is closed and inaccessible ejiction opening 19 (with reference to Fig. 1 (b)), and therefore, the air that sprays under the effect of electric blower 5 can not discharged outside equipment from ejiction opening 19.Wherein, as described later, air door 22 (electric blower 5 is producing in the process of attraction) under the cleaning state is necessarily opened, but in this convenience in order illustrating, to regard as at cleaning state lower wind door 22 and close.
Like this, the air in the air flow circuit 11 is discharged outside equipment from exhaust outlet 10 and conduit outlet 18, but the part of air of discharging descending to floor X side like that shown in thick dashed line arrow among Fig. 1 (a) also rearward flowed simultaneously.At this, conduit outlet 18 towards floor X side (back downside) and successfully (can not block the edge that is suspended in the rear surface 9 conduit outlet 18) and draw electric wire 6 to floor X side, therefore, the air of discharging from conduit outlet 18 flows energetically to floor X side especially.Thus, can produce that dust on the floor X is subjected to from the influence that is sprayed onto the air (discharge currents) on the floor X after exhaust outlet 10 and conduit outlet 18 are discharged and this unfavorable condition of kicking up.
Therefore, in order to solve this unfavorable condition, air door 22 shown in Fig. 1 (b) and ejiction opening 19 performance functions.
Fig. 3 is the state that air door 22 is opened in the presentation graphs 1.
Under the cleaning state, shown in Fig. 3 (b), be open under the effect of the blast that the portion of air of the airborne arrival air door 22 that air door 22 sprays by electric blower 5 in by air flow circuit 11 (with reference to the thick-line arrow among Fig. 3 (b)) produces, rotate in the mode of upside inclination backward.Thus, ejiction opening 19 upside is backward opened, and the air behind the arrival air door 22 becomes air stream, sprays obliquely upward outside equipment towards the back upside from ejiction opening 19.At this, on the wall 39 that constitutes second inclined plane 21 on the framework 4, towards the face (being called guide surface 40) of framework 4 inside (air flow circuit 11) towards ejiction opening 19 and backward upside tilt.Therefore, go up side flow towards the air of ejiction opening 19 backward by guide surface 40 guiding, therefore, discharge obliquely upward towards the back upside reliably from the air (air stream) that ejiction opening 19 is discharged outside equipment from air flow circuit 11.
Shown in Fig. 3 (a), the air stream (with reference to the heavy line arrow) of discharging obliquely to equipment outside towards the back upside from ejiction opening 19 downside and air (exhaust is flowed, with reference to the thick dashed line arrow among Fig. 1 (a)) collision of to equipment outside, discharging in the past like this from exhaust outlet 10 and conduit outlet 18.Thus, the flow direction of the air of discharging outside equipment from exhaust outlet 10 and conduit outlet 18 is corrected, and shown in thick dashed line arrow among Fig. 3 (a), integral body goes up side flow backward.Therefore, can make the air of to equipment outside, discharging in the air flow circuit 11 mobile upward and, thereby prevent this air to be sprayed onto floor X and the situation that causes the dust on the floor X to be kicked up away from floor X.
In addition, according to this structure,, therefore can successfully carry out exhaust, thereby can suppress the reduction of attraction at exhaust outlet 10 because exhaust outlet 10 is opened all the time.And then as long as drive electric blower 5 (with reference to Fig. 5), air stream just can be automatically from ejiction opening 19 ejections, collide with exhaust stream from exhaust outlet 10 and conduit outlet 18, so can prevent without difficultyly that the dust on the floor from kicking up.
Thus, in the electric dust collector 1 with the structure that prevents that the dust on the floor from kicking up, the reduction that can suppress attraction also realizes the raising of ease of use simultaneously.
And, when the driving of electric blower 5 (with reference to Fig. 5) stops, electric blower 5 does not produce attraction, therefore air does not flow in air flow circuit 11, therefore there has not been to push open the air (blast dies down) of air door 22, air door 22 is closed inaccessible once more ejiction opening 19 (also with reference to Fig. 1 (b)) under the effect of deadweight.Thus, can prevent that outside dust from entering in the framework 4 from ejiction opening 19.In addition, under this state, the structure in the framework 4 can not exposed from ejiction opening 19, so aesthetic appearance is good.
Like this, by only utilizing blast and the so simple structure of deadweight, air door 22 can make ejiction opening 19 open and close.
Fig. 4 is the vertical view of electric dust collector 1.
At this, as shown in Figure 4, be provided with integratedly in the rear surface 9 of framework 4 outside framework 4 and (in Fig. 4 for downwards) outstanding a pair of anti-rib pads 25 backward.Above-mentioned anti-rib pads 25 devices spaced apart and broad ways are arranged, and the first above-mentioned inclined plane 20 and second inclined plane 21 are between above-mentioned anti-rib pads 25.Above-mentioned anti-rib pads 25 from width clip the ejiction opening 19 on first inclined plane 20 and air door 22 (in other words, be positioned at ejiction opening 19 and air door 22 around), more side-prominent more backward than first inclined plane 20 and second inclined plane 21.In addition, under this state, observe from width, first inclined plane 20 and second inclined plane 21 are positioned at the inboard (with reference to Fig. 1 (a) and Fig. 3 (a)) of the profile of anti-rib pads 25.
First inclined plane 20, second inclined plane 21 and air door 22 are by above-mentioned anti-rib pads 25 protections.Therefore, even under following situation, air door 22 can not bear external force and breakage yet, described situation is meant: object on every side bumps against main body of dust collector 2, perhaps 9 sides drop to floor X (with reference to Fig. 1 (a)) to main body of dust collector 2 from the rear surface, and main body of dust collector 2 is erected.
Fig. 5 is the right side cross-sectional view of main body of dust collector 2 of the electric dust collector 1 of variation.Fig. 6 is air door 22 closing state in the presentation graphs 5.
(with reference to Fig. 1～Fig. 4) compare, trickle part is different for the main body of dust collector 2 of the electric dust collector 1 of variation shown in Figure 5 and the main body of dust collector 2 of the foregoing description.In addition, in variation, the part with the foregoing description repetition is marked identical symbol and omits its explanation.In Fig. 5, figure is shown with above-mentioned electric blower 5, air flow circuit 11 and filter 24.
In this variation and the foregoing description, in air flow circuit shown in Figure 5 11, the air that is inhaled into air flow circuit 11 from flexible pipe 3 (with reference to Fig. 1 (a)) through filters 24 side flow backward, and is inhaled into electric blower 5 from air entry 8 shown in the thick dashed line arrow.At this, in electric blower 5, be formed with the ejiction opening 26 that is used for the inhaled air ejection at the lower surface of electric blower 5, the air that is drawn into electric blower 5 is by ejiction opening 26 ejections, in air flow circuit 11, temporarily flow downwards thus from electric blower 5.And, in framework 4, be provided with partition wall 38 near the position adjacent ejiction opening 26 of rear side and electric blower 5.Therefore, ejiction opening 26 from electric blower 5 downwards flow air be separated wall 38 and block, thus can be immediately towards rear side, but in air flow circuit 11 temporary transient side flow forward, then with side flow and towards the rear surface 9 of framework 4 backward after the mode that flows around the electric blower 5 rises.
And, in near in the air flow circuit 11 the arrival rear surface 9 the air, portion of air is discharged outside equipment from exhaust outlet 10 or conduit outlet 18 (with reference to Fig. 2) earlier shown in the thick dashed line arrow, on the other hand, remaining air shown in the heavy line arrow towards ejiction opening 19, upwards discharge outside equipment from ejiction opening 19 then.That is, on the flow direction of the air in air flow circuit 11, ejiction opening 19 is positioned at downstream.As mentioned above, the air of upwards discharging outside equipment from ejiction opening 19 will be modified to up from the mobile of air that exhaust outlet 10 and conduit outlet 10 are discharged outside equipment.
At this, we can say that electric blower 5 makes the air after the suction temporarily flow from electric blower 5 downwards, with the mode that around electric blower 5, the flows back guiding exhaust outlet 10 that rises.Thus, can be in framework 4 air be remained on high as far as possible position and then discharge, therefore, can make the air of discharging from exhaust outlet 10 away from floor X by exhaust outlet 10.Therefore, can prevent the situation that the dust on the floor is kicked up because of exhaust reliably.
Next, about variation shown in Figure 5, describe the air door 22 that opens and closes ejiction opening 19 in detail.The rear surface 9 of framework 4 comprises from the upper end (front end) on the first above-mentioned inclined plane 20 the 3rd inclined plane 27 (division face) that upside backward tilts, and forms the recess 28 that caves in (divisions) oriented front side by first inclined plane 20 and the 3rd inclined plane 27 on rear surface 9.Observe from width, recess 28 forms the general triangular shape that attenuates to the front side, and elongated on width.Ejiction opening 19 is arranged at the part of the preceding downside of recess 28 in recess 28.
And the axle 37 that broad ways is extended is inserted logical with respect to the leading section of air door 22, and air door 22 is the center with axle 37, rotates freely between the closed position of the open position of opening ejiction opening 19 (with reference to Fig. 5) and inaccessible ejiction opening 19 (with reference to Fig. 6).When driving electric blower 5, air door 22 is opened under the effect of above-mentioned blast and is positioned at open position, when the driving of electric blower 5 stops, looking clockwise rotating ormal weight and move to closed position, inaccessible ejiction opening 19 (with reference to Fig. 6) under the observation under the effect of above-mentioned deadweight around the right side.
At this, air door 22 rotates in recess 28.Therefore, the open position of air door 22 and the rotary motion trace Y between the closed position (with reference to Fig. 6) are positioned at recess 28.Thus; even something bumps against the rear surface 9 of framework 4 or main body of dust collector 2 and drops to floor X or the user steps near the air door 22 of rear surface 9 from rear surface 9 sides; owing to become protection portion 41 around the recess 28 on the rear surface 9; near air door 22 and ejiction opening 19, air door 22 and ejiction opening 19 are protected; therefore, breakage can not take place in air door 22 and ejiction opening 19 yet.And, around on framework 4, forming recess 28, making recess 28, be arranged on so simple structure in the recess 28 as protection portion 41 and with air door 22 and ejiction opening 19, can prevent reliably that air door 22 and ejiction opening 19 from breaking down.In addition, 9 not outstanding because air door 22 is configured in the recess 28 from the rear surface, therefore can realize the miniaturization of main body of dust collector 2.
And, to observe from width, the air door 22 that is positioned at open position as shown in Figure 5 connects airtight with respect to the 3rd inclined plane 27 from the back downside from axle 37 upside inclination backward.At this moment, the rear end of air door 22 (part that can expose to the outside from recess 28 in the air door 22) is positioned at recess 28 (that is, the positions of 9 depressions from the rear surface), connects airtight with the 3rd inclined plane 27.Therefore, the air door 22 that is positioned at open position can not caught and move by finger tip, can prevent that the air door 22 of open position from by careless moving damaged situation being taken place.
On the other hand, observe from width, the air door 22 that is positioned at the closed position as shown in Figure 6 extends with 20 almost parallel ground, first inclined plane from axle 37 downside inclination backward.At this moment, air door 22 is positioned at the position than first inclined plane, 20 forward downsides (framework 4), in the past the inaccessible ejiction opening 19 (closing) of downside.Promptly, the end face 22A of the back upside that the air door 22 that is arranged in the closed position can expose to the outside from recess 28 is than (to the part of ejiction opening 19 edgeds) the first inclined plane 20 deflection frameworks 4 that are formed with ejiction opening 19, under this state, seamlessly inaccessible ejiction opening 19.Therefore, almost very close to each other between the air door 22 of the edge of the ejiction opening 19 on first inclined plane 20 and closed position, therefore, it is rotated, thereby can prevent the breakage of the air door 22 of closed position.
On the structure that air door 22 is closed because of deadweight being opened by blast like that as mentioned above, for frivolous tabular, strength ratio is lower.Therefore, when something bumped against air door 22 or forces mobile air door 22, air door 22 may be damaged.Yet; as mentioned above; by air door 22 being configured in the recess 28 or utilizing anti-rib pads 25 protection air doors 22; thereby prevent the breakage of air door 22; therefore, the intensity of air door 22 need not be brought up to more than necessity, in addition; also need not use the structure of the complexity of having utilized motor or spring etc., just can realize opening and closing the structure of air door 22 by blast and deadweight.
Fig. 7 represents the state that the main body of dust collector 2 of the electric dust collector 1 of variation erects.
When after cleaning, taking in electric dust collector 1 or make in order to clean high position air entry 8 towards above the time, as shown in Figure 7, on the framework 4 not to be bottom surface 16 but rear surface 9 erects main body of dust collector 2 from top and the opposed mode of floor X.
At this, in the main body of dust collector 2 of the electric dust collector 1 of variation shown in Figure 7, on the rear surface 9 of framework 4, above-mentioned anti-rib pads 25 not only is arranged on width two outsides (with reference to Fig. 4) of air door 22, also is arranged on the upside (being the right side in Fig. 7) of exhaust outlet 10.Therefore, when main body of dust collector 2 is erected, on rear surface 9, only above-mentioned anti-rib pads 25 is from top and floor X butt, therefore, part beyond the anti-rib pads 25 is with respect to the state of floor X for separating, thereby can prevent exhaust outlet 10, conduit outlet 18 (with reference to Fig. 2) and ejiction opening 19 because floor X and the situation of obturation.Certainly, anti-rib pads 25 can prevent when main body of dust collector 2 erects also that air door 22 from bumping against floor X and damaged situation.
Fig. 8 is the major part right side cross-sectional view of main body of dust collector 2 of the electric dust collector 1 of variation.
Fig. 8 represents the lower portion of framework 4 in the main body of dust collector 2.
The lower portion of framework 4 constitutes framework bottom 29, have above-mentioned bottom surface 16, about side 14 (with reference to Fig. 4) and the lower portion of rear surface 9.In addition, framework 4 possesses the cover 30 with above-mentioned first inclined plane 20, second inclined plane 21 and air door 22, and cover 30 can 29 separation from the framework bottom.
At this, cover 30 is the ducted bodies that form the general triangular that attenuates to rear side from the observed cross section of width, and width is long.And, cover 30 has the vertical plane 31 between the lower end on the upper end of generally perpendicularly extending and being erected at first inclined plane 20 and second inclined plane 21 in Fig. 8, mark off cross sectional shape (profile) from the observed cover 30 of width by first inclined plane 20, second inclined plane 21 and vertical plane 31.
And the lower portion 31A of this vertical plane 31 is more side-prominent forward than upper portion 31B, this lower portion 31A be formed with cover 30 internal communication expose mouthfuls 32.Expose mouth 32 and be the long essentially rectangular shape of width.In addition, in cover 30, the position identical with the upper portion 31B of vertical plane 31 is provided with cancellate frame 33 on fore-and-aft direction.Frame 33 from rear side with to expose mouthfuls 32 opposed.
In addition, with cover 30 explicitly, be formed with the opening 34 that is communicated with air flow circuit 11 (with reference to Fig. 5) in the rear side upper end of framework bottom 29.Opening 34 forms the long essentially rectangular shape of width, but littler than exposing mouth 32 on above-below direction.
Be installed under the state of framework bottom 29 at cover 30, exposing of cover 30 mouthfuls 32 is communicated with opening 34, when attraction (produce above-mentioned) part of flow air in air flow circuit 11 (with reference to Fig. 5) flows into afterwards and covers in 30 in order by opening 34 and expose mouthfuls 32 during electric dust collector 1 running.At this, in cover 30, dispose silencer-filter 35 (with putting the part that all is coated with a little).Silencer-filter 35 forms and forms long block-shaped of width by polyurethane etc.The air that flows in the cover 30 is discharged outside equipment at ejiction opening 19 by silencer-filter 35 backs.When air passed through silencer-filter 35, the mobile sound of air was absorbed by silencer-filter 35 and disappears.Therefore, the sound (exhaust sound) of the air of discharging from ejiction opening 19 is very little.
And, will cover 30 when making main body of dust collector 2 etc. when being installed to framework bottom 29, at first, silencer-filter 35 is installed to and covers 30 from exposing mouthfuls 32.At this, silencer-filter 35 is bigger slightly than exposing mouth 32.Therefore, silencer-filter 35 exposes mouthfuls 32 and be assembled on the cover 30 by being pressed into temporarily,, is contained in the cover 30 from exposing under mouthfuls 32 states that expose to the front side at front end face.At this moment, above-mentioned frame 33 contacts with silencer-filter 35 from rear side, and therefore, silencer-filter 35 is side shifting backward not.
Next, exposing mouth 32 under rear side and opening 34 opposed states, will cover 30 from rear side and be installed to framework bottom 29.So, in the framework bottom 29 to the upper end of opening 34 and the part of lower end edged (being called edge 29A) from the place ahead with from exposing mouthful 32 silencer-filters that expose, 35 butts.Thus, silencer-filter 35 is in by the state of the frame 33 of the edge 29A of framework bottom 29 and cover 30 from the front and back clamping, and locatees on fore-and-aft direction.That is, if cover 30 is installed on framework bottom 29, then the position of silencer-filter 35 is fixing automatically.
Thus, silencer-filter 35 not being fixed in cover 30 or framework bottom 29 even do not utilize special-purpose parts or band, also can be by only will covering 30 operations that are installed on framework bottom 29, the position of silencer-filter 35 is completely fixed.
Because the position of silencer-filter 35 is completely fixed like this, therefore, as mentioned above, at air during by silencer-filter 35, silencer-filter 35 not can because of this air from cover 30 and framework bottom 29 peel off or come off.
The present invention is not limited to the embodiment of above explanation, can carry out various changes within the scope of the claims.For example, the present invention also can be applicable to the rechargeable electric dust collector that does not possess electric wire 6 and conduit outlet 18.
In addition, about air door 22, also can be suitable for variation shown in Figure 9.In Fig. 9, be the major part right side cross-sectional view of main body of dust collector 2 of the electric dust collector 1 of variation (a), (b)～(d) be the major part enlarged drawing of (a).
At this, in Fig. 9, in air door 22 towards the leading section of the lower surface 22B of air flow circuit 11 be provided with integratedly observe from width under with lower surface 22B roughly quadrature and the aileron 42 to air flow circuit 11 in, given prominence to.Aileron 42 forms elongated lamellar of width.In Fig. 9 (a), the air door 22 of closing downside backward tilts, and on the other hand, aileron 42 downside forward extends.
Under the situation that is provided with such aileron 42, under air door 22 closing state, (in other words, the wind speed of exhaust) variation and changing, air door 22 also can open to greatest extent (maximum angle) all the time even above-mentioned blast is along with the output of electric blower 5 (with reference to Fig. 5).
Specifically, shown in thick-line arrow, when flow air in the air flow circuit 11 arrives air door 22 shown in Fig. 9 (b), bump against the lower surface 22B of air door 22, as mentioned above, push air door 22 open towards air door 22.At this moment, strong if air will be pushed the power (above-mentioned blast) of air door 22 open, then air door 22 can be fast and is opened to (with reference to Fig. 9 (d)) to greatest extent reliably, but under the situation a little less than the blast, shown in Fig. 9 (c), only opens to midway.At this moment, air door 22 is with respect to flow air in air flow circuit 11 (with reference to big thick-line arrow in two thick-line arrow shown in Fig. 9 (c)) almost parallel, therefore, flow air in air flow circuit 11 (blast) can't be impacted air door 22 effectively, and air door 22 is difficult to further open from the state that opens to midway.
At this, towards shown in two medium and small thick-line arrow of thick-line arrow of part of air shown in Fig. 9 (c) of air door 22 like that, main body of dust collector 2 in, flow and, bump against aileron 42 around the front side of arriving air door 22 along the wall 43 of dividing air flow circuit 11.At this moment, aileron 42 forms to become with respect to this a part of air and hinders such (with respect to this a part of air mobile not parallel) attitude, therefore, aileron 42 also bears blast except that lower surface 22B, further push air door 22 thus open, even a little less than the above-mentioned blast, the result also shown in Fig. 9 (d) like that, can open to greatest extent.
