And; this wall portion 161 under state chorista 86 being installed to above housing section 85 by sealing gasket 163 being crimped on the inclination face 101 of housing section 85; in other words; by flange part 163b being clamped in to the tip side of wall portion 161 and tilting between face 101, between the outer circumferential side of the inside of spatial portion 96, housing section 85 and wall portion 161 (under than the central shaft position of the 2nd centrifugation portion 93 (the cylinder portion 141 of circling round) part) outside zoning accumulate with the 2nd centrifugation portion 93 separated dust be the dust reservoir 165 of thin dirt D.
This dust reservoir 165 is positioned at the 1st centrifugation portion 90 upsides around, is positioned at the outside of the stream of the air by dust collect plant 27, drives electric blower 39 and in fact the negative pressure that produces does not act on this dust reservoir 165, and air does not flow.
And; this wall portion 161 utilize thin dirt D that this inclination has made by each the 2nd centrifugation portion 93 separation go to each the 2nd centrifugation portion 93 below (under)---the position of departing from respect to the Bu Xiang side, central shaft position of these the 2nd centrifugation portions 93, guiding dust reservoir 165.
Ventilation air channel portion 92 is the part that the 1st centrifugation portion 90 is connected airtightly with each the 2nd centrifugation portion 93, spread all between the cylinder portion 132 of the 1st air channel body 121 and pipe section 133 and the 2nd air channel body 122 and import the connecting cylinder portion 135 of air channel body 123 and convolution portion 136 between zoning airtightly, by convolution portion 136, be communicated with each the 2nd centrifugation portion 93 (inside of the cylinder portion 141 of circling round).
This ventilation air channel portion 92 makes the flow of dust laden air form from upstream side (downstream of the 1st centrifugation portion 90) side (upstream side of the 2nd centrifugation portion 93) throttling downstream rectification ground.
Each the 2nd centrifugation portion 93 is, radius of gyration by making dust laden air is less and the velocity ratio that makes to circle round is large in the convolution speed of the 1st centrifugation portion 90 than the radius of gyration in the 1st centrifugation portion 90, by having passed through ratio in the dust laden air of the 1st centrifugation portion 90, by the little dust of dust (relatively) of the 1st centrifugation portion 90 centrifugations, be thin dirt D centrifugation, the unit falling to spatial portion 96.
In other words, each the 2nd centrifugation portion 93 be by dust laden air can not the dust centrifugation of separation in the 1st centrifugation portion 90 unit.And, these the 2nd centrifugation portions 93 by zoning above the 1st centrifugation portion 90, import between the convolution cylinder portion 141 of the convolution portion 136 of air channel body 123 and exhaust portion 137 and separated air channel body 124.
By the dust laden air that has passed through ventilation air channel portion 92 from convolution portion 136 along the tangential direction helically of convolution cylinder portion 141 inner peripheral surfaces import to inside, in the interior convolution of cylinder portion 141 of circling round; the thin dirt D that centrifugation goes out is fallen in spatial portion 96 from bottom; via wall portion 161 to dust reservoir 165 guiding, and by separation thin dirt D, in fact containing the air of dust, from exhaust portion 137, to air channel portion 94, discharge and form (with reference to Fig. 2).
And the central shaft that these spaced-apart intervals about equally of the 2nd centrifugation portion 93 are circular-arc is configured in dust collect plant 27 (the 1st centrifugation portion 90) is around on the position except rear portion (air channel portion 94) (on same circumference).
The cylinder portion 132 of air channel portion 94 use the 1st air channel body 121 and pipe section 133 airtightly zoning in each exhaust portion 137 from the 2nd centrifugation portion 93 to upper cover part 125 and the 2nd air channel body 122.; this air channel portion 94 is communicated with the downstream of all the 2nd centrifugation portion 93; the flow that the side of these the 2nd centrifugation portions 93 of direction from each the 2nd centrifugation portion 93---this example makes air for the 2nd centrifugation Bu93 center that is arranged in circular-arc (sub-circular) gradually throttling ground is continuously, and rearward crooked.
The cleaning action that an above-mentioned example carries out is then described.
When starting cleaning, first chorista 86 is installed to assembling integratedly in housing section 85.Now; by being that lower end side clings to via sealing gasket 163 the inclination face 101 of housing section 85 by the tip side from the outstanding wall portion 161 of chorista 86, by spatial portion 96 zoning dust reservoir 165 between housing section 85 and the outer circumferential side of wall portion 161 of housing section 85.
Then, the dust collect plant 27 this being assembled is installed in body shell 26.That is, make the positioning support portion aligned in position of positioning convex portion etc. and body shell 26 sides and insert outstanding support 32 upper supports by dust collect plant 27 mountings to body shell 26.And by dust collect plant is engaged in the locking opening 153 of body shell 26 with locking claw 152 insertions of clamper 148, dust collect plant 27 is engaged in body shell 26.By the locking of dust collect plant 27, the introducing port 97 of dust collect plant 27 and exhaust port 144 are tightly connected with open communication portion 45 and the air-breathing peristome 46 of body shell 26 respectively.Therefore, dust collect plant 27 is installed in body shell 26 being connected to airtightly under the suction side of electric blower 39 and the state between main body suction inlet 52.
In addition, in the situation that dust collect plant 27 is for to be installed to the state in body shell 26, these operations are unwanted.
Under this state, pipe portion 12 is connected on the main body suction inlet 52 of main body of dust collector 13 (body shell 26).Be specially, tube connector portion 15 inserted and is connected to main body suction inlet 52, and extension tube 18 and floor brush 19 are connected to the tip side of operating portion 17 on hand successively.Under this state, the control circuit portion in the setting button 22 of operating portion 17 and main body of dust collector 13 (body shell 26) etc. is electrically connected on hand.
And user, the socket of extracting power line and wall etc. from cable export mouth out is connected, sets the pattern of electric blower 39 by operating the desirable setting button 22 of handle part 21.
The pattern of control circuit portion and this setting is controlled the input of electric blower 39 accordingly, with the pattern of setting, starts electric blower 39.
The negative pressure that starts this electric blower 39 and produce acts on to pipe portion 12 by filter chamber 37 (filter portion 42), connection air channel portion 38, air-breathing peristome 46, exhaust port 144, air channel portion 94, the 2nd centrifugation portion 93, ventilation air channel portion 92, the 1st centrifugation portion 90, introducing port 97, open communication portion 45, main body air channel portion 33 and main body suction inlet 52.
The effect of user by this negative pressure sucks dust from floor brush 19, extension tube 18 with the top of operating portion 17 (upstream) side on hand together with air.
To be dust laden air import to introducing port 97 via main body suction inlet 52, main body air channel portion 33 and open communication portion 45 from pipe portion 12 this air that comprises dust, from this introducing port 97 to dust collect plant 27 in the i.e. interior suction of the 1st centrifugation portion 90.
In the 1st centrifugation portion 90, dust laden air convolution in convolution air channel 106, the especially thick dirt in dust laden air is centrifuged separation, along the inner peripheral surface 85a of housing section 85, falls, and accumulates in bottom.In addition, the part that this thick dirt is flowed by dust laden air is transported to the occlusion part 109 of inner core 91 from convolution air channel 106, dust laden air by the compression through occlusion part 109 with opening 117 and compressed filter 118 in the interior compression of occlusion part 109.
The separated dust laden air separated filter 112 when the opening 111 of the aiutage portion 108 by inner core 91 falling of thick dirt filters.And then the dust laden air that has passed through this separator-filter 112 by along bottom surface sections 113 downstream side be upside rectification and transport to ventilation air channel portion 92.
Then, flow is by throttling rectification gradually in this ventilation air channel portion 92 for this dust laden air, and by each convolution portion 136, in each the 2nd centrifugation portion 93, (in convolution cylinder portion 141) difference branch also flows into.
In these the 2nd centrifugation portions 93 (convolution cylinder portion 141); dust laden air is along inner peripheral surface (inner peripheral surface of convolution cylinder portion 141) convolution; thin dirt D in this dust laden air is centrifuged separation; along the 2nd centrifugation portion 93 (inner peripheral surface of convolution cylinder portion 141), fall, by wall portion 161, to dust reservoir 165, guided and accumulate.
And, thin dirt D is centrifuged separation, in fact containing the air of dust, from the exhaust portion 137 of each the 2nd centrifugation portion 93 central portions, to air channel portion 94, does not discharge and collaborate, flow is by these air channel portion 94 throttlings rearward guiding, and discharge the outside from exhaust port 144 to dust collect plant 27.
After this, this air is from the air-breathing peristome 46 successively filter 68,69 by connection air channel portion 38 and filter portion 42, to electric blower 39, suck, at the internal cooling of this electric blower 39 and by becoming discharge wind, from electric blower 39, by steam vent 48, to the outside of body shell 26, discharge.
If cleaning finishes, the setting button 22 of user's operating provision, declines the input of electric blower 39 by control circuit portion, and electric blower 39 is stopped.
The in the situation that of having accumulated a certain amount of dust in dust collect plant 27, user lifts dust collect plant and with the operation shank 151 of clamper 148, makes to lock claw 152 and keep out of the way from locking opening 153, and dust collect plant 27 is taken off from body shell 26.
Then; if chorista 86 is taken off from housing section 85; inner core 91 is extracted out from housing section 85 integratedly with chorista 86; and remove wall portion 161 (sealing gasket 163) being close to the face 101 that tilts; the thin dirt D that accumulates in dust reservoir 165 falls along the inside that is tilted to housing section 85 of the face 101 that tilts, and drops to the upside that accumulates in the thick dirt in this housing section 85 and mixes (Fig. 1 (a) and Fig. 1 (b)) with this thick dirt.
Under this state, user is by making upside overthrow obliquely housing section 85 downwards controlling dust collect plant handle portion 98 transports dust collect plant 27 to discarded positions such as dustbins after, and the thick dirt accumulating in housing section 85 with compressed state goes out of use together with the thin dirt D mixing with this thick dirt.
According to illustrated above example; chorista 86 is being installed under the state in housing section 85; from having, that the outstanding wall portion 161 of chorista 86 that has passed through the 2nd centrifugation portion 93 of dust separation less than the dust of the 1st centrifugation portion 90 separation the dust laden air of the 1st centrifugation portion 90 is clung to this housing section 85 (face 101 tilts) is upper, and between housing section 85 and wall portion 161, zoning is accumulated the dust reservoir 165 by the separated thin dirt D of the 2nd centrifugation portion 93.
By this dust reservoir 165 of zoning, by the dust of the 1st centrifugation portion 90 separation, be that thick dirt can accumulate in the 1st centrifugation portion 90 (housing section 85), the dust of the 2nd centrifugation portion 93 separation is that thin dirt D can accumulate in dust reservoir 165.
Therefore, thin dirt D and thick dirt separately can be accumulated under the state of isolation mutually, because thin dirt D is positioned at the outside of the stream of the air by dust collect plant 27, therefore when again driving electric blower 39 grade, thin dirt D can not kick up or again to 93 circulations of the 2nd centrifugation portion because of negative pressure.
And, because dust laden air is in the interior convolution of the 1st centrifugation portion 90, therefore at the inner peripheral surface 85a of housing section 85, easily produce static, but because thin dirt D is not positioned at the 1st centrifugation portion 90 (housing section 85), therefore thin dirt D can reduce the visibility in the 1st centrifugation portion 90 because static is attached on the inner peripheral surface 85a of housing section 85.
And; if take off chorista 86 from housing section 85; housing section 85 (face 101 tilts) is left by wall portion 161; dust reservoir 165 is communicated with the 1st centrifugation portion 90 (housing section 85); the thin dirt D accumulating in dust reservoir 165 falls to the 1st centrifugation portion 90 along the face 101 that tilts, and falls on the thick dirt accumulating in the 1st centrifugation portion 90 and mixes.
Therefore, when discarded dust, by the upside that has taken out the housing section 85 of chorista 86 is tilted to overthrow downwards, the thin dirt D that the state with compression can be accumulated in to the thick dirt in housing section 85 and mix with this thick dirt is simultaneously discarded, compare with opening respectively discarded their situation, discarded labour and time are few.
And because thin dirt D mixes under the state of falling on thick dirt, therefore when the upside of housing section 85 is overthrown downwards obliquely, thick dirt becomes lid and be positioned at the upside of thin dirt D, in the time of therefore can suppressing discarded, thin dirt D's flies upward.
And, by making the diameter dimension of chorista 86 larger than the diameter dimension of housing section 85, owing to can making the inclination more approaching vertical (vertical) of wall portion 161, therefore can positively prevent that the 2nd thin dirt D separated and that fall of centrifugation portion 93 is attached in wall portion 161 residual.
And; by making wall portion 161 be close to the inner side of the inclination face 101 from perimeter sides to the center side housing section 85 that square neck is oblique down chorista 86 being installed under the state in housing section 85; when chorista 86 is taken off from housing section 85, can be more positively tilted to 1st centrifugation portion 90 (housing section 85) the side guiding of the thin dirt D of dust reservoir 165 along the face 101 that tilts will be accumulated in.
And; by possessing the sealing gasket of being close to position 163 of inaccessible wall portion 161 and housing section 85 (face 101 tilts); can more positively block dust reservoir 165 and the 1st centrifugation portion 90 sides, can more positively prevent from accumulating in thin dirt D in dust reservoir 165 and fall, circulate because of the driving of electric blower 39 to the 1st centrifugation portion 90 (housing section 85) side.
And sealing gasket 163 is clamped between wall portion 161 and housing section 85 (face 101 tilts) by flange part 163b, can more positively block dust reservoir 165 and the 1st centrifugation portion 90 sides.
And; because flange part 163b is side-prominent towards the central portion one of the 1st centrifugation portion 90 (housing section 85), the thin dirt D that therefore can prevent from accumulating in dust reservoir 165 enters between the tip side (being mounted the 163a of portion) and flange part 163b of wall portion 161.
In addition, in an above-mentioned example, electric dust collector 11 is not limited to the pattern from external power source with wire coil device, can be also such as the so-called radio-type using batteries such as rechargeable batteries as on-chip power.
And, as electric dust collector 11, be not limited to horizontally, also can be corresponding floor brush 19 be connected to the vertical type of what is called of the bottom of the longilineal body shell 26 of above-below direction for example and use.
And, although understand an example of the present invention, but this example is just as an example proposition, does not limit the intention of invention scope.This new example can be implemented with other various forms, in the scope that does not exceed invention aim, can carry out all omissions, displacement, change.This example and distortion thereof are not only included in scope of invention and aim, are also contained in the scheme recorded in the scope of claim and impartial scope thereof.
