First, about the basic structure of a cyclone separator 10, use Figure 11, Figure 14, Figure 15, Figure 16 and Figure 18 to be described.
One time cyclone separator 10 has: the inflow entrance 11 that the dust laden air from outside flows into; A swirling chamber 12, is formed as substantially cylindrical shape, is tangentially communicated with an inflow entrance 11, makes the dust laden air flowed into from this inflow entrance 11 circle round and be separated air and dust; An outlet 15, discharges the isolated air of dust laden air in this swirling chamber 12.
In addition, also have and be communicated with the Secondary Flow entrance 21 of secondary cyclone separator 20 and a discharge pipe 16 of an outlet 15, and, also have: in an opening portion 13 of the axially opening of a swirling chamber 12; By the dust storage chamber 14 that this opening portion 13 is communicated with swirling chamber 12; Along 0 opening portion 113 of the radial direction opening of a swirling chamber 12; By 0 dust storage chamber 114 that this 0 opening portion 113 is communicated with swirling chamber 12.
0 opening portion 113 is as shown in the amplification plan view of 0 of Figure 18 opening portion 113, and below the opening edge 113a(in the downstream, convolution direction in a swirling chamber 12 is denoted as convolution downstream opening edge) the shape be formed as at least partially with the circle caved on convolution direction.
In said structure, the majority of the rubbish of a swirling chamber 12 is flowed into (hereinafter referred to as rubbish a) by acting on the centrifugal force of rubbish a from an inflow entrance 11, as shown in the rubbish track a in Figure 15, be separated from the swirling air stream in a swirling chamber 12 and become trapped in 0 dust storage chamber 114 by 0 opening portion 113.
But, a part of rubbish (hereinafter referred to as rubbish b) as shown in the rubbish track b in Figure 15, the swirling air stream centrifugation in a swirling chamber 12, but not by 0 opening portion 113, collide convolution downstream opening edge.Now, if make the shape be formed as at least partially with the circle caved on convolution direction of the convolution downstream opening edge 113a in a swirling chamber 12 as described above, then as shown in the arrow in Figure 18, rubbish b moves slidably on convolution downstream opening edge 113a, eliminate and hang to the card of convolution downstream opening edge 113a in the midway of its movement, efficiency can become trapped in 0 dust storage chamber 114 well.
On the contrary, as shown in figure 19, when making convolution downstream opening edge 113a form deviously, rubbish b card hangs over this bending position.In addition, as shown in figure 20, when forming convolution downstream opening edge 113a point-blank, rubbish b blocks the end hanging over this line part sometimes.Like this, when rubbish b card hangs over convolution downstream opening edge 113a, the rubbish b hung with this card is starting point, and the rubbish b flowing into a swirling chamber 12 from inflow entrance 11 afterwards is also accumulated near convolution downstream opening edge 113a, therefore, rubbish a also block hang over convolution downstream opening edge 113a.
Therefore, if make the shape be formed as at least partially with the circle caved on convolution direction of the convolution downstream opening edge 113a in a swirling chamber 12 as described above, suppress rubbish b to hang to the card of convolution downstream opening edge 113a, then efficiency well all rubbish can be trapped 0 dust storage chamber 114.
And as shown in figure 13, outlet 15 is formed highlightedly to the central axis direction of a swirling chamber 12, and the height and position axially at least partially of this outlet 15 is configured in the position lower than the bottom of an inflow entrance 11.By such formation, circle round while there is the speed of central axis direction from the dust laden air of inflow entrance 11 inflow, can from dust laden air separating of garbage efficiently.The shape of 0 opening portion 113 when adopting such structure forms following shape, namely, in order to trap be trapped in 0 opening portion 113 convolution downstream opening edge on rubbish b, in the same manner as the principle of above-mentioned Figure 18, make the shape of the circle caved in the convolution direction being formed as with the swirling air stream in a swirling chamber 12 at least partially of convolution downstream opening edge.That is, owing to producing the swirling air stream of the direction of arrow of Figure 21, the convolution downstream opening edge 113a of 0 opening portion 113 is formed as the shape shown in Figure 21, its result, rubbish b moves slidably on convolution downstream opening edge 113a, eliminate and hang to the card of convolution downstream opening edge 113a in the midway of its movement, 0 dust storage chamber 114 can be become trapped in.
By adopting said structure, with the principle same with above-mentioned explanation, for the rubbish b of speed with axis (direction of arrow of Figure 21), the card to the opening edge of 0 opening portion 113 also can be suppressed to hang, efficiency can become trapped in 0 dust storage chamber 114 well.
In addition, as shown in figure 15, the configuration of 0 opening portion 113 also can be, the central point of the opening surface of 0 opening portion 113 relative to the planar configuration of the central shaft of link 0 dust storage chamber 114 and the central shaft of a swirling chamber 12 at the convolution direction upstream side of suction gas.
By adopting such structure, the part having flowed into the air-flow of 0 dust storage chamber 114 flows as airflow direction A in the dust storage chamber in Figure 15, therefore, when this air-flow A returns a swirling chamber 12, card can be peeled from convolution downstream opening edge and hang over rubbish b the convolution downstream opening edge of 0 opening portion 113.Therefore, it is possible to suppress rubbish b to hang to the card of convolution downstream opening edge, and efficiency can be trapped 0 dust storage chamber 114 well.
On the contrary, as shown in figure 22, when the central point of the opening surface by 0 opening portion 113 relative to downstream, convolution direction in suction gas of the planar configuration of the central shaft of link 0 dust storage chamber 114 and the central shaft of a swirling chamber 12, the part having flowed into the air-flow of 0 dust storage chamber 114 flows as airflow direction B in the dust storage chamber in Figure 22, therefore, when this air-flow B returns a swirling chamber 12, the rubbish b that card can be hung on the opening edge of convolution downstream is pressed against convolution downstream opening edge further.
In addition, as shown in figure 13, one time outlet 15 is made up of the hole on the sidewall being arranged on a discharge pipe 16 outstanding in a swirling chamber 12, and being formed by the cone 16a of roughly conical shape at least partially of a discharge pipe 16, the height and position axially at least partially in the roughly conical shape face of this cone 16a also can be configured in the opening range axially of 0 opening portion 113.
Like this, by providing holes on sidewall highlightedly in a swirling chamber 12, suppress the inhalation power of the axis in a swirling chamber 12, increase the rotating force acting on rubbish, and, by forming the cone shape face of cone 16a, the distance of 0 opening portion 113 and an outlet 15 can be guaranteed, so, can suppress for be separated to via 0 opening portion 113 rubbish of 0 dust storage chamber 114, from the attraction of an outlet 15, and reliably can trap 0 dust storage chamber 114.
In addition, in a cyclone separator 10 of the reversible type shown in present embodiment, one time discharge pipe 16 becomes from the outstanding structure in the top of a swirling chamber 12, but as described above, the attraction from an outlet 15 for rubbish in a swirling chamber 12 is suppressed, so 0 opening portion 113 can be made close to an outlet 15, its result, owing to 0 opening portion 113 can be arranged on the top of a swirling chamber 12, so the degree of depth of 0 dust storage chamber 114 can be made to deepen, that is, can make to increase from the distance of the bottom of 0 113 to 0 time, opening portion dust storage chamber 114, the size of 0 dust storage chamber 114 entirety can not be made to maximize suppress dispersing again of the rubbish in 0 dust storage chamber 114, trapping performance can be improved.Have the following advantages in addition in addition, that is, because cone 16a is roughly conical shape, so when the rubbish of the isometric wire of hair is wrapped on a discharge pipe 16, by making this rubbish move along extreme direction before circular cone, can easily remove.
In addition, as shown in figure 11, also can form an outlet 15 by the hole on the sidewall being arranged on a discharge pipe 16 outstanding in a swirling chamber 12, this hole is arranged on the position except the part near 0 opening portion 113.
By adopting said structure, the rotating force acting on rubbish is increased owing to suppressing the attraction of the axis in a swirling chamber 12, simultaneously, for being separated to the rubbish of 0 dust storage chamber 114, suppressed from the attraction of an outlet 15 via 0 opening portion 113, so reliably rubbish can be trapped 0 dust storage chamber 114.
In addition, as shown in figure 17, also following structure can be adopted, namely, one time outlet 15 is made up of the hole be arranged on a discharge pipe 16 outstanding in a swirling chamber 12, after discharge pipe 16 adopts the axis had along a swirling chamber 12 to be drawn out, bend to the structure of the bend of approximate right angle, by the discharge direction of the bend shown in Figure 16 as shown in figure 23 such planar configuration relative to the central point of link 0 opening portion 113 and the axle of a swirling chamber 12 in the scope of 45 °, both sides.
The flowing of the air in the discharge pipe 16 formed deviously is in this wise described.As shown in figure 17, the wind path in a discharge pipe 16 is bending (hereinafter referred to as bending wind path) generally perpendicularly, and the bending radius being positioned at the air stream (dotted line) of the inner side of this bending wind path is less, is subject to resistance loss.On the other hand, because the bending radius being positioned at the air stream (solid line) in the outside of bending wind path is comparatively large, so the flowing of air is smooth and easy and not by resistance loss, from the speed of the air stream that swirling chamber 12 sucks, its power is strong.As a result, the distribution of the flow velocity of an outlet 15 and the distribution of attraction produce strong and weak.
Therefore, due to the position relationship (be the scope of both sides 45 ° in relative to the plane of the central point of link 0 opening portion 113 and the axle of a swirling chamber 12) of the bending direction of an above-mentioned discharge pipe 16 and 0 opening portion 113, namely, if bent to the direction of 0 opening portion 113, what then the velocity flow profile of an outlet 15 was weak is partly arranged near 0 opening portion 113, and the part that attraction is strong is not configured near 0 opening portion 113, therefore, can suppress for the rubbish being separated to 0 dust storage chamber 114, from the inhalation power of an outlet 15, improve separating property.
In addition, for obtaining above-mentioned effect, in an outlet 15, make velocity flow profile produce strong and weak, be therefore not limited to above-mentioned structure, the angle of bend of the bend 16c of a discharge pipe 16 also can be the situation beyond approximate right angle.
In addition, as shown in figure 13, in a discharge pipe 16, also an outlet 15 can be formed in the region except the part except (the part A that dotted line surrounds) near an inflow entrance 11.
By adopting said structure, can suppress directly to be inhaled into an outlet 15 from the suction gas of inflow entrance 11 inflow, and the flowing that can strengthen further towards convolution direction in a swirling chamber 12, improve the centrifugal force acting on rubbish, improve trapping performance further.
In addition, as shown in figure 13, a part for the sidewall of a discharge pipe 16 also can be made up of the cylinder 16b of cone 16a and the substantially cylindrical shape with a large amount of minute aperture.
Form a discharge pipe 16 as described above, the air-flow entered from inflow entrance 11 can circle round swimmingly a swirling chamber 12 in, therefore, it is possible to improve the centrifugal force acting on rubbish, and improves and traps performance.
In addition, as shown in figure 13, also the altitude range on the rotary shaft direction of an inflow entrance 11 swirling chamber 12 can be made to be positioned at the altitude range axially of cylinder 16b, and the height and position axially of cone 16a also can be configured in beyond the opening range axially of described 0 opening portion 113.
By adopting said structure, cone 165a is configured in opening range on the rotary shaft direction of a swirling chamber 12 of 0 opening portion 113, the distance of the minute aperture of the sidewall of 0 opening portion 113 and outlet body 15 can be guaranteed more reliably, therefore, can suppress for the rubbish dispersed to 0 dust storage chamber 114, from the attraction of the minute aperture of outlet body 15, and improve the catching of rubbish.
In addition, as shown in figure 13, cyclone separator 10 also can have at an opening portion 13 of the lower openings of a swirling chamber 12 and the dust storage chamber 14 of below being configured in a described opening portion 13.
By adopting said structure, can be captured in 0 dust storage chamber 114 not by the rubbish trapped completely by a dust storage chamber 14.And, if make an outlet 15 become the shape with above-mentioned cone 16a, then circle round and arrive the below of a swirling chamber 12 air-flow reversion, can be taken into by cone 16a the air-flow (hereinafter referred to as ascending air) risen in the central authorities of a swirling chamber 12 swimmingly, and improve while gyration airflow can not be upset the trapping performance of rubbish.In addition, by arranging an outlet 15 at the side wall surface of cone 16a, ascending air spreads a little in the horizontal direction, so, the impact of the ascending air that the rubbish dispersed again because of certain reason after being trapped by a dust storage chamber 14 is spread in the horizontal direction and swirling flow, the power risen while convolution.Therefore, then the rubbish dispersed circle round in a swirling chamber 12 while rise, therefore, it is possible to capture 0 dust storage chamber 114.
In addition, as shown in figure 13,0 opening portion 113 also can be arranged between an opening portion 13 and an outlet 15.
By adopting said structure, the rubbish that can will disperse again from dust storage chamber 14, captures 0 dust storage chamber 114 in the midway of rising towards an outlet 15 near.
In addition, as shown in figure 13, the sidewall of a swirling chamber 12 also can by of substantially cylindrical shape time cylindrical portion 12b and time conus portion 12a, and the shape of a conus portion 12a is the shape behind the front end of cutting away more less close to point diameter roughly circular cone.
By adopting said structure, rubbish by self inertia force and centrifugal force along a swirling chamber 12 inwall convolution while arrive the below of a swirling chamber 12, now, its convolution speed reduces because of wall friction and air drag, but by the wall of the roughly conical shape of a conus portion 12a, radius of gyration is reduced, thus, can guarantee to be directly proportional to the quadratic power of convolution speed and the centrifugal force be inversely proportional to radius of gyration, therefore, it is possible to rubbish is trapped a dust storage chamber 14 efficiently.And, there is following effect: the amount suppressing the air of an inflow dust storage chamber 14, and suppress dispersing again of the rubbish of an arrival dust storage chamber 14.
In addition, as shown in figure 13, conus portion 12a also can be roughly the same relative to the angle of inclination of the axis of centres of a swirling chamber 12 with cone 16a or be below it relative to the angle of inclination of the axis of centres of a swirling chamber 12.
By adopting said structure, the wind path sectional area of the convolution wind path (wind path except except a discharge pipe 16) in a swirling chamber 12 does not reduce in a conus portion 12a, thus, the pressure loss can be suppressed, and guarantee the wind path of the upwelling of swirling chamber 12 central authorities, therefore, it is possible to prevent the interference of swirling flow and ascending air, and improve trapping performance.In addition, owing to ensure that the distance between the wall of a conus portion 12a and cone 16a, so the rubbish that the internal face along a conus portion 12a circles round can be suppressed to be inhaled into from cone 16a.
Below, about the structure of secondary cyclone separator 20, Figure 10, Figure 12, Figure 16 is used to be described.Secondary cyclone separator 20 has: the Secondary Flow entrance 21 being taken into dust laden air from discharge pipe 16; Secondary swirling chamber 22, is roughly tangentially connected with Secondary Flow entrance 21, thus, from the dust laden air convolution that Secondary Flow entrance 21 imports.Circle round making the suction gas flowed into from Secondary Flow entrance 21 and after isolating dust, this suction gas discharged from secondary outlet 25.In addition, there is the secondary discharge pipe 26 guided to exhaust wind path 51 by the Exhaust Gas from this secondary outlet 25.
In addition, secondary discharge pipe 26 is formed as follows, that is, its axle is roughly consistent with the axle of secondary swirling chamber 22, and it is outstanding in secondary swirling chamber 22, has secondary outlet 25 in its bottom.
In addition, the sidewall of secondary swirling chamber 22 is made up of the cylindrical portion 22b of substantially cylindrical shape and the conus portion 22a of roughly conical shape.In addition, the secondary opening portion 23 formed while there is a part of opening of conus portion 22a and the secondary dust storage chamber 24 be communicated with secondary swirling chamber 22 via secondary opening portion 23.
About the action of secondary cyclone separator 20, its summary is described.Secondary cyclone separator 20 is taken into dust laden air via a discharge pipe 16 from Secondary Flow entrance 21, and this dust laden air comprises the rubbish that could not be captured in a cyclone separator 10.This dust laden air substantially horizontally flows into along the sidewall of secondary swirling chamber 22, therefore becomes gyration airflow, forms the forced vortex region near central shaft and the semi-free vortex stream region of its outer circumferential side, by its path configuration and gravity, flows downward meanwhile.Now, because centrifugal action is in rubbish, so the rubbish be not captured completely in a cyclone separator 10 be pressed against secondary swirling chamber 22 inwall on and be separated from suction gas, after entering the below of secondary swirling chamber 22 along with the swirling flow declined, become trapped in secondary dust storage chamber 24 via secondary opening portion 23.The air being removed rubbish rises along the central shaft of secondary swirling chamber 22, discharges from secondary outlet 25.The air of discharging from secondary outlet 25 is imported into exhaust wind path 51 by secondary discharge pipe 26.
In addition, as shown in the embodiment, by carrying a cyclone separator 10 and secondary cyclone separator 20 on electric dust collector 100, can reliably from dust laden air separating of garbage dust.Therefore, due to the quantity of the filter in filter or minimizing wind path can not used in wind path, so the electric dust collector 100 being not easy to cause air quantity to reduce because of plugged filter can be provided.In addition, even if only carry the cyclone suitable with cyclone separator 10 on electric dust collector 100, or only carry the cyclone suitable with secondary cyclone separator 20, also can obtain above-mentioned effect.
In addition, in the above-described embodiment, the electric dust collector having carried secondary cyclone separator 20 is illustrated, but also only can carries a cyclone separator 10, or multiple cyclone separator (secondary cyclone separator, three cyclone separators are set ...).In addition, the present invention relates to the structure of cyclone dust collecting unit, the form of electric dust collector is not limited to the electric dust collector of the pot type illustrated in present embodiment.
In addition, in the above-described embodiment, make the minute aperture of cone 16a and cylinder 16b become connection there is the inside and outside hole of certain thickness wall and be illustrated, but be not limited thereto, such as, structure that also can be such by the cancellated structure of pasting filter in framework forms minute aperture.
Industrial applicibility
The present invention can be applicable to cyclone separator and carry the electric dust collector of cyclone separator.
