Diffuser 23 in the front side that diffuser keeps body 38, is for example fixed by screw, and the shell aperture portion 27 of covering body housing 22 is to seal.And to shown in Figure 4, this diffuser 23 has as Fig. 2: diffuser body 56, and it has predetermined diameter dimension as the current plate body; Upstream rectifying plate 57, its from the front principle face of this diffuser body 56 towards the front side, promptly towards centrifugal cutter 24 side-prominent settings; And downstream current plate 58, its from the back principle face of this diffuser body 56 towards rear side, promptly towards motor 21 side-prominent settings.
In addition, on the periphery of this diffuser body 56, equally spaced cut the notch 62 that is formed with a plurality of general triangular of expanding gradually to the central side width along Zhou Fangxiang, periphery forms flexuose.
Upstream rectifying plate 57 near therefrom septum cordis the periphery of the distance of the size more bigger than the diameter dimension of centrifugal cutter 24, forms the circular arc wall shape with respect to diffuser body 56 approximate vertical, and be plane whirlpool shape, mutually roughly equally spaced dispose a plurality of.
In addition, the end edge of the central side that is positioned at diffuser body 56 of these upstream rectifying plates 57 is relative with centrifugal cutter 24, in the inboard of upstream rectifying plate 57, roughly is the cylindric fan accommodation section 64 of accommodating centrifugal cutter 24 that marks off.
The end of the upstream rectifying plate 57 of the peripheral side of diffuser body 56, be positioned at not on the outer periphery of the locational diffuser body 56 that is cut by notch 62, between upstream rectifying plate 57,57, divide and form guiding wind path 66, it is on the peripheral direction of diffuser body 56, and width is expanded gradually and is connected with notch 62.
Here, along with upstream rectifying plate 57 is big from the outstanding quantitative change of diffuser body 56, air quantity also increases, if overhang diminishes, then degree of vacuum increases, and therefore in the present embodiment, the outstanding size t1 (Fig. 3) from diffuser body 56 sets for upstream rectifying plate 57, is the prearranging quatity that 9.5mm～10mm reduces than the upstream rectifying plate of electric blower in the past from the outstanding size of diffuser body, for example is 9mm.
In addition, on upstream rectifying plate 57, in the end of the outer circumferential side that is positioned at diffuser body 56 and be positioned on the edge in the outside, be provided with along the periphery curvature of diffuser body 56 and cut the bearing surface 68 that forms.And, on upstream rectifying plate 57, in the end of fan accommodation section 64 sides that are positioned at the central side that becomes diffuser body 56 and be positioned in the outer ledge portion, be provided with guiding plane of inclination 69, it is along with forming thin-walled near central side, and guide guides air in wind path 66, and can not produce turbulent flow in the edge section.
Here, quantity minimizing when upstream rectifying plate 57, and the width dimensions of guiding wind path 66,66 is when enlarging, the air that blows out from centrifugal cutter 24 can not be the outer circumferential side that the whirlpool shape is directed to diffuser body 56 effectively, causes electric blower efficient to reduce, on the other hand, quantity increase when upstream rectifying plate 57, and the width dimensions of guiding wind path 66 is when reducing, and increases with the surface friction drag of air flowing and causes electric blower efficient to reduce, and noise also increases simultaneously.Therefore, by upstream rectifying plate 57 being set at for example 13, thereby when can guaranteeing electric blower efficient, can reduce noise to greatest extent.
On the other hand, downstream current plate 58 forms the circular arc wall shape with respect to diffuser body 56 approximate vertical, and is going up in the opposite direction with the whirlpool side of upstream rectifying plate 57, is plane whirlpool shape and roughly equally spaced disposes a plurality of mutually.Between these downstream current plates 58,58, divide to be formed with and flow through wind path 71.
In addition, on downstream current plate 58, in the end of the outer circumferential side that is positioned at diffuser body 56 and be positioned at the edge part in the outside, be provided with and flow through plane of inclination 72, its with respect to the periphery curvature almost parallel of diffuser body 56 be cut open formation, and guiding air in flowing through wind path 71, and can not produce turbulent flow in the edge section.
And downstream current plate 58 is set at prearranging quatity, for example 13mm from the outstanding size t2 (Fig. 3) of diffuser body 56.Be that downstream current plate 58 is set to, bigger from the overhang of diffuser body 56 than the overhang of upstream rectifying plate, be about 1.44 times.
Here, the quantity of these downstream current plates 58 forms the non-integral multiple of upstream rectifying plate 57, and more than the quantity of this upstream rectifying plate 57.These downstream current plates 58, for example be under 16 the situation, the maximum value of noise reduces, the strong noise that occurs also reduces on the predetermined frequency band of peak shape, therefore by downstream current plate 58 is set at 16, thereby when guaranteeing electric dust collector efficient, can also reduce noise to greatest extent.
Therefore, as shown in Figure 4, the spacing P1 of downstream current plate 58,58 is littler than the spacing P2 of upstream rectifying plate 57,57, and spacing P2 is the non-integral multiple of spacing P1.Therefore, as each opening H1 of the upstream side of the inflow side of downstream current plate 58, and near the position as each opening H2 in the downstream side of the outflow side of upstream rectifying plate 57 this opening H1, the Zhou Fangxiang that constitutes at diffuser 23 relatively staggers.
In addition, the opening area S1 of each opening H1 of the upstream side of downstream current plate 58, be that sectional area between the outer periphery portion of downstream current plate 58,58 forms, than the opening area S2 of each opening H2 of downstream side of upstream rectifying plate 57, promptly the sectional area between the outer periphery portion of upstream rectifying plate 57,57 is big.Particularly, downstream current plate 58 is 13mm from the outstanding size t2 (Fig. 3) of diffuser body 56, when the beeline between the outer periphery portion of downstream current plate 58,58 was 4mm, opening area S1 was set at the product of above-mentioned two sizes, i.e. S1=13 * 4=52mm
2Upstream rectifying plate 57 is 9mm from the outstanding size t1 (Fig. 3) of diffuser body 56, and when the beeline between the outer periphery portion of upstream rectifying plate 57,57 was 4.5mm, opening area S2 was set at the product of above-mentioned two sizes, i.e. S2=9 * 4.5=40.5mm
2Therefore, the gross area of the upstream side opening of downstream current plate 58 is S1 * 16=832mm
2, the gross area of the downstream side opening of upstream rectifying plate 57 is S2 * 13=526.5mm
2, the gross area of the upstream side opening of downstream current plate 58 become upstream rectifying plate 57 the downstream side opening the gross area about 158%.
Turn back to Fig. 1, centrifugal cutter 24 for produce by rotation and air between the heat that produces of friction have heat resistance, and inertia and weight when considering rotation are for example formed by aluminum alloy etc., above-mentioned centrifugal cutter 24 has: discoideus lower plate 75; Separate predetermined gap and opposed upper plate 76 with this lower plate 75; And be bonded on fan blade 77 between these lower plates 75 and the upper plate 76.
Fan blade 77 forms the both sides of the edge that make its length direction and engages with lower plate 75 and upper plate 76 respectively and be the wall shape, and is formed on the whirlpool side of the fan blade 77 of centrifugal cutter 24 and goes up in the opposite direction.In addition, this fan blade 77 in the both sides of the edge of length direction, outstanding is provided with that a plurality of insertions are separately positioned in the slit on lower plate 75 and the upper plate 76 and by welding the not shown claw that (welding) etc. and lower plate 75 are connected with upper plate 76.And, between lower plate 75 and upper plate 76, connect and fuse by this fan blade 77, mark off a plurality of circinate air inlet wind paths 81 by opposed lower plate 75 and upper plate 76 and fan blade 77.
Here, it is as follows that upstream rectifying plate 57 is set at 13 and result that the relation between electric blower efficient and the noise is experimentized: though be less than in fan blade 77 under 9 the situation, electric blower efficient has the tendency of raising, but noise increases simultaneously, find that particularly the noise with more predetermined frequency becomes big peak shape part, and, in the stage less to the input voltage of electric blower 6, the noise climbing is bigger, the inclination that is the peak increases, and finds to begin just to have the tendency that becomes big noise from the less stage of input voltage.Particularly when fan blade 77 was 7 and 8, the climbing of noise was bigger.
Therefore, according to the efficient and the noise properties of these electric blowers, under the condition of the diameter dimension of above-mentioned diffuser 23 and centrifugal cutter 24 etc., preferably fan blade 77 is set at 9.
In addition, centrifugal cutter 24, by the lining (sleeve) 84 chimeric with rotor shaft 48, and with the hexagon nut 86 that the screw section 85 of the toe lateral that is formed on this rotor shaft 48 screws togather, be clamped between the packing ring 87,87, and be fixed on the front end of armature 46.
