The cross-sectional side view of the A-A section of Fig. 4, Fig. 5 presentation graphs 3 and B-B section overlook sectional drawing.In casing 2, be provided with air-supply path 10, this air-supply path 10 connects the first blow-off outlet 4a, the second blow-off outlet 4b, the 3rd blow-off outlet 4c and suction inlet 5.In air-supply path 10, dispose fan 8.Fan 8 is made up of cross flow fan (axial-flow fan), and utilize fan motor 8a to drive moving blade (not shown) and rotate, and along continuous straight runs configuration turning cylinder.Utilize the driving of fan motor 8a, fan 8 is air-breathing and to the circumferencial direction exhaust from the circumferencial direction of moving blade (not shown).Also can form fan 8 by the centrifugal fan of turning cylinder along continuous straight runs configuration.
In air-supply path 10 and in the downstream of fan 8, what be disposed with that a plurality of along continuous straight runs cut apart first cuts apart path 10 a, second and cuts apart path 10 b and the 3rd and cut apart path 10 c.First cuts apart path 10 a, second cuts apart path 10 b and the 3rd and cuts apart path 10 c and offer the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c at front end respectively.In addition, first cuts apart path 10 a and the 3rd and cuts apart the sidewall 10f in the inboard sidewall 10e of path 10 c and the outside and formed by the curved surface with respect to the vertical guide inclination.
Cut apart path 10 a, second first and cut apart path 10 b and the 3rd and cut apart in the path 10 c and, be formed with vertical direction expansion section 11 and axial expansion section 12 respectively in the downstream of fan 8.Vertical direction expansion section 11 makes flow channel enlarge gradually along the vertical direction of fan 8 turning cylinders.Axially expansion section 12 makes the axially gradually expansion of flow channel along fan 8 turning cylinders in the downstream of vertical direction expansion section 11, and vertically dwindles gradually.
In addition, axially the flow channel area of expansion section 12 enlarges towards downstream more more.In addition, first cut apart path 10 a, second cut apart path 10 b and the 3rd cut apart path 10 c and vertical direction expansion section 11 and axially expansion section 12 form continuously.
Cut apart path 10 a, second first and cut apart path 10 b and the 3rd and cut apart in the path 10 c, the electrode 7a of particulate generation device 7,7b expose configuration.Electrode 7a and electrode 7b are cut apart path 10 a, second first and are cut apart path 10 b and the 3rd and cut apart and be configured to respectively in the path 10 c separated by next door 10d.
Apply the voltage that is interchange waveform or impulse waveform to electrode 7a, 7b.7a applies positive voltage to electrode, and the ion that utilizes ionization to produce combines with airborne moisture, mainly by H +(H 2O) electric charge of m formation forms positive cluster ion.7b applies negative voltage to electrode, and the ion that utilizes ionization to produce combines with airborne moisture, mainly by O 2 -(H 2O) electric charge of n formation forms negative cluster ion.Wherein, m, n are any natural number.

In the micro-particle diffusing device 1 of said structure, if drive fan 8 and particulate generation device 7 then are drawn into indoor air in the casing 2 from suction inlet 5.After being drawn into air in the casing 2 and being filtered device 6 and filtering dust, in air-supply path 10, circulate and be directed to fan 8.
The exhaust of fan 8 is cut apart path 10 a, second to first and is cut apart path 10 b and the 3rd and cut apart path 10 c shunting, and is directed to the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c respectively.At this moment, if the configuration of the turning cylinder vertical of fan 8 then makes the air-flow on the left and right directions inhomogeneous because of centrifugal force.Therefore, through the turning cylinder of horizontal arrangement fan 8, can make the air-flow of left and right directions even.And because first cut apart path 10 a and the 3rd and cut apart the inboard sidewall 10e of path 10 c and tilt with respect to vertical guide, the air-flow along tangent to periphery direction straight ahead turns to so can easily make from fan 8.
In addition, flow channel broadens in vertical direction expansion section 11 along the vertical direction, and flow channel 12 broadens along left and right directions in axial expansion section.Relying on than axial expansion section 12 in the vertical direction expansion section 11 at the upper reaches, bigger to the centrifugal forces affect of the fan 8 of circumferencial direction exhaust.Therefore, in order to make air-flow, do not broaden about not hoping towards advancing with the vertical direction of fan 8 turning cylinders.And, broaden along the vertical direction in vertical direction expansion section 11 through making flow channel, reclaim the kinetic energy of air-flow and convert static pressure to, thereby improved static pressure.Thus, can improve the draft capacity of micro-particle diffusing device 1.In addition, can make the fixed width of flow channel left and right directions in vertical direction expansion section 11, it is dwindled slightly.At this moment, the flow channel area enlarges towards downstream gradually.
In axial expansion section 12, because under the state that the centrifugal force that is produced by fan 8 dies down, flow channel enlarges along left and right directions, thus can not make the pressure loss become big, thus turn to with can making airflow smooth and broaden along left and right directions.In addition, owing to flow channel narrows down along the vertical direction, thus air-flow is broadened along left and right directions more swimmingly, and can suppress air velocity decline.At this moment, because axially the flow channel area of expansion section 12 enlarges towards downstream gradually, so in axial expansion section 12, also can reclaim kinetic energy and convert static pressure to, thereby can improve static pressure.In addition, can make the width of flow channel above-below direction keep fixing, also can make the flow channel area keep fixing in axial expansion section 12.
Utilize particulate generation device 7, make first to cut apart path 10 a, second and cut apart path 10 b and the 3rd and cut apart in the air-flow of circulation in the path 10 c and contain cation and anion.Thus, see the air-flow that contains cation and anion off from the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c.
The state of the air-flow of the indoor D that Fig. 6 representes to see off from micro-particle diffusing device 1.Circulate along roof T to right-hand first air current A of seeing off 1 from the first blow-off outlet 4a, and descend along right-hand sidewall (the first wall P1).Second air current A of forwards seeing off from the second blow- off outlet 4b 2 circulates along roof T, and the edge sidewall (second wall P2) relative with the sidewall S that disposes micro-particle diffusing device 1 descends.The 3rd air current A of seeing off to left from the 3rd blow-off outlet 4c 3 circulates along roof T, and descends along the sidewall (the 3rd wall P3) of left.
The air-flow that descends along the first wall P1, the second wall P2 and the 3rd wall P3 circulates on indoor ground F, and back along sidewall S rising, as to return micro-particle diffusing device 1 suction inlet 5.Thus, can make air-flow arrive each indoor corner along each indoor wall circulation and with ions diffusion.In addition, utilize, make ion gently be diffused into the living space of indoor central portion along the air-flow of wall circulation.Because first, second, third air current A 1, A2, A3 utilize wall attachment effect to advance along wall, weakened by indoor air so can suppress kinetic energy.Thus, can suppress power consumption, and can make the arrival of air-flow big apart from change.
In addition, can whenever switch the polarity of the ion that produces by electrode 7a, 7b at a distance from specified time limit.That is, produce cation and produce anion from electrode 7b from electrode 7a.If through specified time limit, then produce anion and produce cation from electrode 7b from electrode 7a.If pass through specified time limit again, then produce cation and produce anion, and repeat above-mentioned action from electrode 7b from electrode 7a.
Thus, make first to cut apart path 10 a, second and cut apart path 10 b and the 3rd and cut apart the left end and the right-hand member of the air-flow seen off of broadening about path 10 c and alternately see cation and anion off.Therefore, can make cation and anion be distributed to the broad range of left and right directions in the room with high concentration.
According to this embodiment; Have the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c that along continuous straight runs is set up in parallel; See first air current A 1 off from the first blow-off outlet 4a; This first air current A 1 descends along roof T circulation and along the first wall P1, sees second air current A 2 off from second blow-off outlet, and this second air current A 2 descends along roof T circulation and the edge second wall P2 relative with sidewall S; And seeing the 3rd air current A 3, the three air current A 3 off from the 3rd blow-off outlet 4c descends along roof T circulation and edge the 3rd wall P3 relative with the first wall P1.
Thus, first, second, third air current A 1, A2, A3 utilize wall attachment effect to advance along wall, are weakened by indoor air so suppressed kinetic energy.That is, when air-flow not when roof T flows, the last side directed surrounding air of air-flow (air between roof T and the air-flow), kinetic energy is by surrounding air weakening and lose.When air-flow is mobile along roof T, though, compare very little usually with the kinetic energy that air-flow does not lose when roof T flows because of the frictional resistance of wall makes kinetic energy rejection.In the air conditioner in the past of above-mentioned patent documentation 2 records, because air-flow is flowed along roof T, so kinetic energy is weakened by surrounding air, the arrival distance of air-flow correspondingly shortens.
Therefore, this embodiment can make the arrival of air-flow big apart from change, and can make ions diffusion arrive each indoor corner.Therefore, can realize power saving, and owing to can directly to the living space air-flow be provided, so can reduce user's uncomfortable feeling, and it is indoor that ion is diffused into fully.
In addition; Because the turning cylinder horizontal arrangement of the fan 8 that centrifugal fan or axial-flow fan constitute; And air-supply path 10 has first cutting apart path 10 a, second and cut apart path 10 b and the 3rd and cut apart path 10 c of cutting apart in the downstream of fan; And first cuts apart path 10 a and the 3rd cuts apart the inboard sidewall 10e of path 10 c and tilts with respect to vertical guide, thus can make air-flow on left and right directions evenly, and can easily make along the air-flow of tangent to periphery direction straight ahead and turn to.
In addition; Vertical direction expansion section 11 makes flow channel enlarge gradually along the vertical direction of fan 8 turning cylinders, and axially expansion section 12 make flow channel in the downstream of vertical direction expansion section 11 axially enlarging gradually and vertically dwindle gradually along fan 8 turning cylinders.Thus, can prevent to cause mass flow discrepancy even, and can make air-flow axially broadening along fan 8 turning cylinders because of the centrifugal force of fan 8.
And, because at 11 places, vertical direction expansion section in fan 8 downstream, the flow channel area can not dwindle, so can fully reclaim the kinetic energy of air-flow and improve static pressure.After this, the speed that has suppressed air-flow at axial 12 places, expansion section descends and air-flow is broadened vertically.Thus, the arrival that the rotating speed of fan 8 is accelerated just can make air-flow is apart from becoming big.Therefore, can realize the province's electrification and the low noiseization of micro-particle diffusing device 1, and it is indoor that ion is diffused into fully.
In addition, at 11 places, vertical direction expansion section, the influence of the centrifugal force of fan 8 is bigger, even the width of flow channel left and right directions broadens gradually, the effect that broadens about air-flow also can descend, and the performance of fan 8 is descended.Therefore, can make the width of flow channel left and right directions keep fixing at 11 places, vertical direction expansion section, it is dwindled slightly.In addition, can make the width of flow channel above-below direction keep fixing at axial 12 places, expansion section.
In addition, because axially the flow channel area of expansion section 12 enlarges towards downstream more more, so in axial expansion section 12, also can reclaim kinetic energy and convert static pressure to, thereby further improve static pressure.In addition, also can make the flow channel area keep fixing at axial 12 places, expansion section.At this moment,, utilize vertical direction expansion section 11 recovery kinetic energy, can improve static pressure with comparing in the past though axially the recover kinetic energy of expansion section 12 descends.
In addition; Cut apart path 10 b and the 3rd and cut apart path 10 c and vertical direction expansion section 11 and link to each other because a plurality of first cuts apart path 10 a, second with axial expansion section 12; And axially cutting apart along fan 8; So air-flow is cut apart path 10 a, second along first and is cut apart the wall circulation that path 10 b and the 3rd is cut apart path 10 c, thereby can make air-flow axially broadening swimmingly along fan 8.
In addition, the turning cylinder horizontal arrangement of fan 8 and with casing 2 be configured in indoor roof T near, and the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c be formed on the upper end of casing 2 and see air-flow off along roof T.Thus, the air-flow of seeing off along roof T utilizes wall attachment effect to circulate along roof T.Therefore, can further make the arrival distance of air-flow elongated.
Then, Fig. 7 representes the cross-sectional side view of the micro-particle diffusing device of second embodiment.For the ease of explanation, adopt identical Reference numeral with said Fig. 1～same part of first embodiment shown in Figure 6.In this embodiment, with first embodiment likewise the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c that are set up in parallel of level in the bottom of casing 2 the front surface opening.In addition, suction inlet 5 is in the upper surface open of casing 2.Other parts are identical with first embodiment.
Have predetermined gap H between the casing 2 of micro-particle diffusing device 1 and the roof T, and be installed on the indoor sidewall S.First cuts apart path 10 a, second cuts apart path 10 b and the 3rd and cuts apart path 10 c (with reference to Fig. 4) square neck is oblique up with predetermined angular with respect to horizontal direction.Thus, first air current A 1, second air current A 2 and the 3rd air current A 3 arrive after the roof T, circulate along roof T.

The 4th air current A of seeing off from the 4th blow-off outlet 4d 4 descends along sidewall S.At this moment, the flow of the 4th air current A 4 for example is below about 10% or 10% of second air current A, 2 flows less than the flow of second air current A 2.Because first, second, third air current A 1, A2, A3 is in whole indoor circulation and return suction inlet 5, so there is near the not enough situation of ion the sidewall S.Therefore, the 4th air current A 4 descends to replenish near the ion the sidewall along sidewall S, and returns suction inlet 5 with first, second, third air current A 1, A2, the A3 that rise along sidewall S.
According to this embodiment, owing to have the 4th blow-off outlet 4d, and flow along the sidewall S that disposes micro-particle diffusing device 1 from the 4th air current A 4 that the 4th blow-off outlet 4d sees off, so can replenish near the ion the sidewall S.At this moment, with respect to first, second, third air current A 1, A2, the A3 that return suction inlet 5, the 4th air current A 4 becomes resistance.But, because the flow of the 4th air current A 4 is less than the flow of second air current A 2, so can suppress the resistance by 4 generations of the 4th air current A.In addition, also can in said second embodiment shown in Figure 7, the 4th blow-off outlet 4d be set.
Then, Fig. 9 representes the cross-sectional side view of the micro-particle diffusing device of the 4th embodiment.For the ease of explanation, adopt identical Reference numeral with said Fig. 1～identical part of first embodiment shown in Figure 6.This embodiment makes second to cut apart path 10 b in the further shunt of front end.Other parts are identical with first embodiment.

The first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c are arranged on the upper end of casing 2, see flow air off along roof T (with reference to Figure 13).Of the back in detail, to the right-hand air of seeing off, the second blow-off outlet 4b forwards sees air off from casing 2 to the first blow-off outlet 4a from casing 2, and the 3rd blow-off outlet 4c sees air from casing 2 off to left.In addition, the 4th blow-off outlet 4d sees air downwards off.
Figure 13, Figure 14 represent cross-sectional side view and the cross-sectional side view of E-E section of the D-D section of Figure 12.In casing 2, dispose the fan 30 that cross flow fan (axial-flow fan) constitutes.Fan 30 is covered the impeller 33 of cross-flow type by first shell 31 and second shell 32.
Impeller 33 is driven by fan motor 33a (with reference to Figure 10) and rotates the turning cylinder horizontal arrangement.Utilize the driving of fan motor 33a, fan 30 is air-breathing and to the circumferencial direction exhaust from the circumferencial direction of impeller 33.First shell 31 and second shell 32 axially are set up in parallel along impeller 33, dispose second shell 32 in the both sides of first shell 31.
In casing 2, be provided with from the first air-supply path 10 of first suction inlet 5a leaked-in air circulation and the second air-supply path 20 of circulating from the second suction inlet 5b leaked-in air.The air flow passage in impeller 33 downstreams in the first air-supply path 10 is formed by first shell 31, and the air flow passage in impeller 33 downstreams in the second air-supply path 20 is formed by second shell 32.
End at first shell 31 offers the first suction side peristome 31a, and about half cycle of impeller 33 is from the outstanding configuration of the first suction side peristome 31a.Near the first suction side peristome 31a, the gap between the impeller 33 and first shell 31 forms minimum.The flow channel area of impeller 33 upstream sides in the first air-supply path 10 is greater than the first suction side peristome 31a.The wall of first shell 31 is with the curvature bending of regulation, and offers the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c at its front end.Thus, form the first air-supply path 10, this first air-supply path 10 connects the first blow-off outlet 4a, the second blow-off outlet 4b, the 3rd blow-off outlet 4c and the first suction inlet 5a.
End at second shell 32 offers the second suction side peristome 32a, and about half cycle of impeller 33 is from the outstanding configuration of the second suction side peristome 32a.Near the second suction side peristome 32a, the gap between the impeller 33 and second shell 32 forms minimum.The flow channel area of impeller 33 upstream sides in the second air-supply path 20 is greater than the second suction side peristome 32a.The wall of second shell 32 is with the curvature bending of regulation, and offers the 4th blow-off outlet 4d at its front end.Thus, form the second air-supply path 20 that connects the 4th blow-off outlet 4d and the second suction inlet 5b.
In addition, from end on observation, near the first suction side peristome 31a of first shell 31, shape that moving center rotates behind the angle θ of regulation is consistent with the second suction side peristome 32a from second shell 32 prescribed limit to be rotated.Thus, the opening surface of the first suction side peristome 31a is configured to different angles in a circumferential direction with the opening surface of the second suction side peristome 32a.
Therefore, can make first shell 31 and second shell 32 be formed at the fan 30 that cross flow fan constitutes, and form the flow channel of the exhaust side in the first air-supply path 10 and the second air-supply path 20 with optimum shape.Thus, the air-flow of circulation can sharply not turn in the first air-supply path 10 and the second air-supply path 20, can reduce the pressure loss and improve air-supply efficient, and can reduce noise.
Figure 15 represent Figure 12 the C-C section overlook sectional drawing.In the first air-supply path 10 and in the downstream of fan 30, what be disposed with that a plurality of along continuous straight runs cut apart first cuts apart path 10 a, second and cuts apart path 10 b and the 3rd and cut apart path 10 c.First cuts apart path 10 a, second cuts apart path 10 b and the 3rd and cuts apart path 10 c and offer the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c at front end respectively.In addition, first cuts apart path 10 a and the 3rd and cuts apart the sidewall 10f in the inboard sidewall 10e of path 10 c and the outside and formed by the curved surface with respect to the vertical guide inclination.
Cut apart path 10 a, second first and cut apart path 10 b and the 3rd and cut apart in the path 10 c, and in the downstream of fan 30, be formed with vertical direction expansion section 11 and axial expansion section 12 (with reference to Figure 14) respectively.Vertical direction expansion section 11 makes flow channel enlarge gradually along the vertical direction of fan 30 turning cylinders.Axially expansion section 12 makes flow channel axially enlarging gradually and vertically dwindle gradually along fan 30 turning cylinders in the downstream of vertical direction expansion section 11.In addition, axially expansion section 12 is oblique with the predetermined angular square neck that makes progress with respect to horizontal direction.
In addition, axially the flow channel area of expansion section 12 enlarges towards downstream more more.In addition, first cut apart path 10 a, second cut apart path 10 b and the 3rd cut apart path 10 c and vertical direction expansion section 11 and axially expansion section 12 form continuously.
Cut apart path 10 a, second first and cut apart path 10 b and the 3rd and cut apart in the path 10 c, electrode 7a, the 7b of particulate generation device 7 same as described above expose configuration.Electrode 7a and electrode 7b are cut apart path 10 a, second first and are cut apart path 10 b and the 3rd and cut apart and be configured to respectively in the path 10 c separated by next door 10d.In addition, as aforementioned shown in Figure 13, in the second air-supply path 20, electrode 7a, the 7b of same particulate generation device 7 also expose configuration.
In the micro-particle diffusing device 1 of said structure, if drive fan 30 and particulate generation device 7 then are drawn into indoor air in the casing 2 from the first suction inlet 5a and the second suction inlet 5b.After being drawn into air in the casing 2 and being filtered device 6 and filtering dust, in the first air-supply path 10 and the second air-supply path 20, circulate and be directed to fan 30.
The air-flow of circulation blows out to the back lower place from the 4th blow-off outlet 4d in second shell 20 in the second air-supply path 20.And, flow down along the sidewall S that micro-particle diffusing device 1 is installed.
The air-flow of circulation in first shell 31 in the first air-supply path 10 is cut apart path 10 a, second to first and is cut apart path 10 b and the 3rd and cut apart path 10 c shunting.And each air-flow is directed to the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c.At this moment, if the configuration of the turning cylinder vertical of fan 30 then makes the air-flow on the left and right directions inhomogeneous because of centrifugal force.Therefore, through making the turning cylinder horizontal arrangement of fan 30, can make the air-flow of left and right directions even.And because first cut apart path 10 a and the 3rd and cut apart the inboard sidewall 10e of path 10 c and tilt with respect to vertical guide, the air-flow along tangent to periphery direction straight ahead turns to so can easily make from fan 30.
In addition, flow channel broadens in vertical direction expansion section 11 along the vertical direction, and flow channel 12 broadens along left and right directions in axial expansion section.Relying on than axial expansion section 12 in the vertical direction expansion section 11 at the upper reaches, bigger to the influence of the centrifugal force of the fan 30 of circumferencial direction exhaust.Therefore, in order to make air-flow, do not broaden about not hoping towards advancing with the vertical direction of fan 30 turning cylinders.Through flow channel is enlarged in vertical direction expansion section 11 along the vertical direction, reclaim the kinetic energy of air-flow and convert static pressure into, thereby improved static pressure.Thus, can improve the draft capacity of micro-particle diffusing device 1.In addition, can make the fixed width of flow channel left and right directions, it is dwindled slightly at 11 places, vertical direction expansion section.At this moment, the flow channel area enlarges towards downstream gradually.
In axial expansion section 12, because under the state that the centrifugal force that fan 30 produces dies down, flow channel enlarges along left and right directions, thus can not make the pressure loss become big, thus turn to with can making airflow smooth and broaden along left and right directions.In addition, owing to flow channel narrows down along the vertical direction, thus air-flow is broadened along left and right directions more swimmingly, and can suppress air velocity decline.At this moment, because axially the flow channel area of expansion section 12 enlarges towards downstream gradually, thus in axial expansion section 12, also can reclaim kinetic energy and convert static pressure to, thus static pressure improved.In addition, can make the width of flow channel above-below direction keep fixing, also can make the flow channel area keep fixing in axial expansion section 12.
Utilize particulate generation device 7, make in the air-flow that circulates in the first air-supply path 10 and the second air-supply path 20 and contain cation and anion.Thus, see the air-flow that contains cation and anion off from the first blow-off outlet 4a, the second blow-off outlet 4b, the 3rd blow-off outlet 4c and the 4th blow-off outlet 4d.
The state of the air-flow of the indoor D that Figure 16 representes to see off from micro-particle diffusing device 1.Circulate along roof T to right-hand first air current A of seeing off 1 from the first blow-off outlet 4a, and descend along right-hand sidewall (the first wall P1).Second air current A of forwards seeing off from the second blow- off outlet 4b 2 circulates along roof T, and the edge sidewall (second wall P2) relative with the sidewall S that disposes micro-particle diffusing device 1 descends.The 3rd air current A of seeing off to left from the 3rd blow-off outlet 4c 3 circulates along roof T, and descends along the sidewall (the 3rd wall P3) of left.
The 4th air current A of seeing off from the 4th blow-off outlet 4d 4 descends along the sidewall S that disposes micro-particle diffusing device 1.At this moment, the flow of the 4th air current A 4 for example is about 10% of second air current A, 2 flows less than the flow of second air current A 2.
The air-flow that descends along the first wall P1, the second wall P2 and the 3rd wall P3 circulates on indoor ground F, and first back along sidewall S rising, as the to return micro-particle diffusing device 1 suction inlet 5a.In addition, indoor portion of air is returned the second suction inlet 5b from the top of micro-particle diffusing device 1.Thus, can make air-flow arrive each indoor corner along each indoor wall circulation and with ions diffusion.In addition, utilize, make ion gently be diffused into the living space of indoor central portion along the air-flow of wall circulation.Because first, second, third air current A 1, A2, A3 utilize wall attachment effect to advance along wall, weakened by indoor air so can suppress kinetic energy.
That is, when air-flow not when roof T flows, the last side directed surrounding air of air-flow (air between roof T and the air-flow), kinetic energy is by surrounding air weakening and lose.When air-flow is mobile along roof T, though, compare very little usually with the kinetic energy that air-flow does not lose when roof T flows because of the frictional resistance of wall makes kinetic energy rejection.Thus, can suppress power consumption also can make the arrival of air-flow big apart from change.
In addition, because first, second, third air current A 1, A2, A3 is in whole indoor circulation and return the first suction inlet 5a, so there is near the not enough situation of ion the sidewall S.Therefore, the 4th air current A 4 descends along sidewall S, can replenish near the ion of sidewall.At this moment, because the flow of the 4th air current A 4 is less than the flow of second air current A 2, so can suppress the resistance by 4 generations of the 4th air current A.
In addition, because the axial expansion section 12 in the first air-supply path 10 is oblique with the predetermined angular square neck that makes progress with respect to horizontal direction,, circulate along roof T so can make first air current A 1, second air current A 2 and the 3rd air current A 3 after arriving roof T.But first air current A 1, second air current A 2 and the 3rd air current A 3 are before arriving roof T, and kinetic energy is weakened.Therefore, shorten, preferably gap H is set in below the 30cm, and the angle of inclination that preferably makes the air-flow of circulation in the axial expansion section 12 is below 20 °, so that airflow smooth ground flows along roof T in order to make apart from the distance of roof T.
In addition, can whenever switch the polarity of the ion that produces by electrode 7a, 7b at a distance from specified time limit.That is, produce cation and produce anion from electrode 7b from electrode 7a.If through specified time limit, then produce anion and produce cation from electrode 7b from electrode 7a.If pass through specified time limit again, then produce cation and produce anion, and repeat above-mentioned action from electrode 7b from electrode 7a.
Thus, make first to cut apart path 10 a, second and cut apart path 10 b and the 3rd and cut apart the left end and the right-hand member of the air-flow seen off of broadening about path 10 c and alternately see cation and anion off.Therefore, can make cation and anion be distributed to the broad range of left and right directions in the room with high concentration.
According to this embodiment; Because first, second shell 31,32 axially being set up in parallel of the covering impeller 33 of fan 30 along impeller 33; And the blow-off direction that flows through air-flow wherein respectively is different, so just can see air-flow off to a plurality of directions through simple structure.Therefore, can easily make ions diffusion arrive each indoor corner.In addition, because air-flow can sharply not turn to, reduce, thereby improve air-supply efficient, and can reduce noise so can prevent the pressure loss.
In addition; First shell 31 at one end offers the first suction side peristome 31a that impeller 33 is given prominence to; And extend to the exhaust side of impeller 33, second shell 32 at one end offers the second suction side peristome 32a that makes impeller 33 outstanding, and extends to the exhaust side of impeller 33.And the opening surface of the opening surface of the first suction side peristome 31a and the second suction side peristome 32a is configured to different angles on the circumferencial direction of impeller 33.Thus, can simply first, second shell 31,32 be formed the low optimum shape of the pressure loss with respect to fan 30.In addition, can be easily the blow-off direction (front upper place) of the air-flow that flows through first shell 31 and the blow-off direction (back lower place) that flows through the air-flow of second shell 32 be formed and differ more than 90 °.
In addition; Because end on observation from impeller 33; First shell 31 apart from the first suction side peristome 31a prescribed limit; Consistent with the shape of second shell 32 after the center of rotation of impeller 33 is rotated apart from the second suction side peristome 32a prescribed limit, so can form first, second shell 31,32 of optimum shape more simply.
In addition and since utilize first shell 31 towards the front upper place to the indoor air-flow of seeing off, and utilize second shell 32, so can easily make ions diffusion arrive each indoor corner towards the indoor air-flow of seeing off of lower direction.In addition, when gap H hour, also can utilize first shell 31 to blow out air-flow to horizontal direction.
In addition and since utilize first shell 31 towards the front upper place to the indoor air-flow of seeing off, and utilize second shell 32, so can easily make indoor air circulation to each corner towards the indoor air-flow of seeing off of lower direction.In addition, when gap H hour, also can utilize first shell 31 to blow out air-flow towards horizontal direction.
Also can omit particulate generation device 7 in first～the 5th embodiment, but adopt circulator, this circulator utilising first, second, third, fourth air current A 1, A2, A3, A4 make indoor air-flow circulation.At this moment,, weakened by indoor air, thereby the arrival that can make air-flow is apart from becoming big so can suppress kinetic energy because first, second, third air current A 1, A2, A3 utilize wall attachment effect to advance along wall.Therefore, can realize power saving, and owing to can directly to the living space air-flow be provided, so can reduce user's uncomfortable feeling, and can make indoor air circulation fully.
Then, Figure 17, Figure 18 represent the stereogram and the cross-sectional side view of the micro-particle diffusing device of the 6th embodiment.For the ease of explanation, adopt identical Reference numeral with said Fig. 1～identical part of first embodiment shown in Figure 6.Micro-particle diffusing device 1 is covered by casing 2, and this casing 2 is formed by resin forming product.The bottom surface of casing 2 becomes the face that is provided with indoor ground F butt, thereby micro-particle diffusing device 1 is placed on the F of ground.In addition, micro-particle diffusing device 1 can be configured near the angle, room between a sidewall S and the ground F.
Bottom at casing 2 front surfaces and the back side offers suction inlet 5, and this suction inlet 5 is drawn into indoor air in the casing 2.On the upper surface relative of casing 2, offer first blow-off outlet 43 and second blow-off outlet 53 that blow out air-flow with the face that is provided with.In detail as the back said, be configured in the rear portion first blow-off outlet 43 aperture area less than the configuration fore second blow-off outlet 53 aperture area.
In casing 2, dispose fan 40.Figure 19 representes the front sectional drawing of fan 40.Fan 40 comprises motor 9, and this motor 9 has the turning cylinder 9a of direction extension to the left and right, and first, second impeller 41,51 is installed on turning cylinder 9a.Thus, first, second impeller 41,51 arranged coaxial, and driven and rotate by motor 9.
First impeller 41 has: plectane 41a, and 9a is connected with turning cylinder; And a plurality of blade 41b, on radial two surfaces that uprightly are arranged on plectane 41a.Equally, second impeller 51 has: plectane 51a, and 9a is connected with turning cylinder; And a plurality of blade 51b, on radial two surfaces that uprightly are arranged on plectane 51a.
First impeller 41 and second impeller 51 are configured in respectively in first shell 42 and first shell 52 that forms air flow passage.Between first, second shell 42,52 and casing 2 and first, second shell 42, be formed with the gap of ormal weight between 52, the gap of this ormal weight makes from suction inlet 5 (with reference to Figure 17) leaked-in air circulation in casing 2.
First shell 42 has the first cylindrical portion 42a and first and blows out passage 42c.The first cylindrical portion 42a is cylindric for the cardinal principle that covers first impeller 41, and offers the first air entry 42b in axial both ends of the surface.First blows out passage 42c extends along the tangent to periphery direction towards the top from the periphery of the first cylindrical portion 42a, and offers first blow-off outlet 43 (with reference to Figure 18) at front end.
Equally, first shell 52 has the second cylindrical portion 52a and second and blows out passage 52c.The second cylindrical portion 52a is cylindric for the cardinal principle that covers second impeller 11, offers the second air entry 52b in axial both ends of the surface.Second blows out passage 52c extends along the tangent to periphery direction towards the top from the periphery of the second cylindrical portion 52a, and offers second blow-off outlet 53 (with reference to Figure 18) at front end.
Thus, fan 40 constitutes the centrifugal fans (Sirocco fan or turbofan) that join more, and utilizes the rotation of first, second impeller 41,51, and is air-breathing and to the circumferencial direction exhaust to axially from first, second air entry 42b, 52b.
Shown in figure 18, the first cylindrical portion 42a and the second cylindrical portion 52a are configured to observe from the side unanimous on the whole.And first blows out direction and second that passage 42c extends from the first cylindrical portion 42a, and to blow out passage 52c different in a circumferential direction from the direction of second cylindrical portion 52a extension.The direction of the air-flow that blows out from first, second blow- off outlet 43,53 thus, is different.That is, shown in arrow B 1, towards the vertical top or with respect to seeing air-flow off towards square after a while back upper place above the vertical, shown in arrow B 2, see air-flow off to the front upper place from second blow-off outlet 53 from first blow-off outlet 43.
In addition, first blow out passage 42c flow channel is enlarged along square with the axis direction at the upstream portion 42d in the first cylindrical portion 42a downstream gradually.In addition, the downstream portion 42e in upstream portion 42d downstream dwindled flow channel gradually along square with the axis direction before arriving first blow-off outlet 43.Second blows out passage 52c enlarges flow channel gradually along square with the axis direction between the second cylindrical portion 52a and second blow-off outlet 53.Thus, the width of the direction that first blow-off outlet 43 is square with the axis is less than the width of the square with the axis direction of second blow-off outlet 53, and the aperture area of first blow-off outlet 43 is less than the aperture area of second blow-off outlet 53.
In first, second blew out passage 42c, 52c, a plurality of electrodes (not shown) of particulate generation device 7 same as described above exposed configuration.
In the micro-particle diffusing device 1 of said structure, if motor of drive fan 40 9 and particulate generation device 7 then are drawn into indoor air in the casing 2 from suction inlet 5.The air that sucks in the casing 2 passes through first, second air entry 42b, 52b, flows in first, second shell 42,52.The air that flows into first, second shell 42,52 is discharged to circumferencial direction from first, second cylindrical portion 12a, 22a, and in first, second blows out passage 42c, 52c, circulates.The air that in first, second blows out passage 42c, 52c, circulates contains ion, and blows out towards the direction of arrow B 1, B2 respectively from first, second blow- off outlet 43,53.
At this moment and since flow channel first blow out passage 42c the upstream portion 42d edge direction vertical with turning cylinder 9a broaden, so can reclaim the kinetic energy of air-flow and convert static pressure to, thereby improve static pressure.Thus, can improve the draft capacity of fan 40.In addition, because the flow channel downstream part 42e edge direction vertical with turning cylinder 9a narrows down, descend so can suppress the speed of air-flow.Thus, can see high speed airflow off from the first less blow-off outlet 43 of aperture area.
Therefore, the air that blows out towards above the vertical or back upper place from first blow-off outlet 43 rises along near the sidewall S the micro-particle diffusing device 1.And above-mentioned air flows through roof, sidewall and the ground F relative with micro-particle diffusing device 1, and returns micro-particle diffusing device 1.In addition, utilize, make ion gently be diffused into the living space of indoor central portion along the air-flow of wall circulation.Thus, can make air-flow along each indoor wall circulation, and make ions diffusion arrive each indoor corner.
Because the air-flow that blows out from first blow-off outlet 43 utilizes wall attachment effect to advance along wall, weakened by indoor air so suppressed kinetic energy.That is, when air-flow not when wall flows, the side surface side guiding surrounding air (air between wall and the air-flow) of air-flow, kinetic energy is weakened by surrounding air and loses.When air-flow is mobile along wall, though, compare very little usually with the kinetic energy that air-flow does not lose when wall flows because of the frictional resistance of wall makes kinetic energy rejection.Thus, can suppress power consumption also can make the arrival of air-flow big apart from change.In addition, also can first blow out passage 42c downstream portion 42e place, make the width of the direction vertical of flow channel keep fixing with turning cylinder 9a.
In addition, second blow out passage 52c flow channel is broadened to second blow-off outlet 53, the edge direction vertical with turning cylinder 9a from the second cylindrical portion 52a.Therefore, reclaim the kinetic energy of air-flow and convert static pressure to, thereby improve static pressure.Thus, can further improve the draft capacity of micro-particle diffusing device 1.And, see the air-flow of low speed off from the second bigger blow-off outlet 53 of aperture area.
The air that utilization blows out to the front upper place from second blow-off outlet 53 replenishes ion to the living space of indoor central portion.In addition, because the air-flow that blows out from second blow-off outlet 53 is a low speed, cause uncomfortable feeling so can prevent the user who directly contacts the living space because of wind.
In addition, can be whenever at a distance from the polarity of switching specified time limit by the ion of each electrode generation of particulate generation device 7.That is, produce cation and produce anion from another electrode from an electrode.If through specified time limit, then produce anion and produce cation from another electrode from an electrode.If pass through specified time limit again, then produce cation and produce anion, and repeat above-mentioned action from another electrode from an electrode.
Thus, alternately see cation and anion off at the left end and the right-hand member of air-flow.Therefore, can make cation and anion be distributed to the broad range of left and right directions in the room with high concentration.
According to this embodiment, utilize a motor 9 to drive first, second impeller 41,51 of arranged coaxial.And; First blows out direction and second that passage 42c extends from the periphery of the first cylindrical portion 42a that covers first impeller 41 blows out the direction of passage 52c from the periphery extension of the second cylindrical portion 21a that covers second impeller 51; Different in a circumferential direction, the blow-off direction (B1) of the air-flow that blows out from first blow-off outlet 43 is different with the blow-off direction (B2) of the air-flow that blows out from second blow-off outlet 53.Thus, just can see air-flow off through simple structure to a plurality of directions.In addition, because air-flow can sharply not turn to, increase, thereby can improve air-supply efficient and reduce noise so can prevent the pressure loss.
In addition, because the aperture area of first blow-off outlet 43 is less than the aperture area of second blow-off outlet 53, so can make the wind speed of the wind speed of first blow-off outlet 43 greater than second blow-off outlet 53.The arrival that thus, can make the air-flow that first blow-off outlet 43 blows out is apart from becoming big.In addition, when indoor living space is seen off, can prevent that the user from feeling uncomfortable at the air-flow that second blow-off outlet 53 is blown out.
In addition, because the width of first blow-off outlet, 43 square with the axis directions is less than the width of second blow-off outlet, 53 square with the axis directions, so can make the wind speed of the wind speed of first blow-off outlet 43 greater than second blow-off outlet 53 simply.
In addition, first blow out passage 42c upstream portion 42d flow channel is enlarged along square with the axis direction gradually, and downstream portion 42e makes flow channel keep fixing or dwindle gradually along square with the axis direction.Therefore, because the upstream portion 42c in first impeller, 41 downstream narrows down the flow channel area, thus can fully reclaim the kinetic energy of air-flow and improve static pressure, thus air-supply efficient can be improved.After this, the speed that downstream part 42e suppresses air-flow descends, and blows out air-flow from aperture area less than first blow-off outlet 43 of second blow-off outlet 53.Thus, the rotating speed of fan 40 is accelerated, the arrival that just can make the air-flow that first blow-off outlet 43 blows out is apart from becoming big.
And second blows out passage 52c makes flow channel enlarge gradually along square with the axis direction, and blows out air-flow from the second bigger blow-off outlet 53 of aperture area.Thus, can fully reclaim the kinetic energy of air-flow and improve static pressure, thereby can improve air-supply efficient, and can easily blow out the air-flow of comparing low speed with first blow-off outlet 43 from second blow-off outlet 53.
In addition, by first shell 42 from first blow-off outlet 43 towards vertical top or the back upper place see air-flow off, and see air-flow from second blow-off outlet 53 off to the front upper place by first shell 52.Therefore, if micro-particle diffusing device 1 is arranged near the angle, room of an indoor sidewall S and ground F, the high velocity air that then blows out from first blow-off outlet 43 flows through this sidewall S, roof, relative sidewall and ground F.Therefore, it is indoor ion to be diffused into fully.And, blow out the air-flow of low speed from second blow-off outlet 53 to indoor living space, thereby can replenish the ion of living space, and can prevent that the user from feeling under the weather.
In addition; Because first, second impeller 41,51 has blade 41b, 21b on two surfaces of plectane 41a, 21a; And first, second air entry 42b, 52b are separately positioned on two axial surfaces of first, second cylindrical portion 42a, 52a, so can easily obtain fan 40 small-sized and that air quantity is bigger.
