Detailed description of the invention
With reference to the accompanying drawings embodiments of the present invention are described.Fig. 1, Fig. 2 and Fig. 3 are the stereogram of micro-particle diffusing device from top view first embodiment, the stereogram observed from below and front view.Micro-particle diffusing device 1 is covered by casing 2, and is configured near the angle, room between an indoor sidewall S and roof T (with reference to Fig. 4).Can casing 2 be arranged on sidewall S, also casing 2 can be arranged on the roof T near sidewall S.
The lower surface of casing 2 offers suction inlet 5.Suction inlet 5 is configured with filter 6.On the front surface top of casing 2, from right side, be arranged in parallel with the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c in the horizontal direction successively towards indoor.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, send air along roof T (with reference to Fig. 4).In detail as described later, the first blow-off outlet 4a sends air to the right from casing 2, and the second blow-off outlet 4b sends air from casing 2 to front, and the 3rd blow-off outlet 4c sends air to the left from casing 2.
Fig. 4, Fig. 5 represent the cross-sectional side view of the A-A section of Fig. 3 and the cross sectional top view of B-B section.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.Fan 8 is configured with in air-supply path 10.Fan 8 is made up of cross flow fan (axial-flow fan), utilizes fan motor 8a to drive moving blade (not shown) to rotate, and configures turning cylinder in the horizontal direction.Utilize the driving of fan motor 8a, fan 8 is from the circumferencial direction air-breathing of moving blade (not shown) and be vented to circumferencial direction.The centrifugal fan that also can be configured in the horizontal direction by turning cylinder is to form fan 8.
In the downstream of fan 8, be disposed with multiple the first segmentation path 10 a, the second segmentation path 10 b and the 3rd split in the horizontal direction and split path 10 c in air-supply path 10.First segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c offer the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c respectively in front end.In addition, the sidewall 10e inside the first segmentation path 10 a and the 3rd segmentation path 10 c and the sidewall 10f in outside is by the Surface forming tilted relative to vertical guide.
In the downstream of fan 8, be formed with vertical direction expansion section 11 and axial expansion section 12 respectively in the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c.Vertical direction expansion section 11 makes flow channel expand gradually along the vertical direction of fan 8 turning cylinder.The downstream of expansion section 11 in the vertical direction, axial expansion section 12 makes flow channel expand gradually along the axis of fan 8 turning cylinder, and vertically reduces gradually.
In addition, the flow channel area of axial expansion section 12 more more expands towards downstream.In addition, the first segmentation path 10 a, the second segmentation path 10 b and the 3rd are split path 10 c and vertical direction expansion section 11 and axial expansion section 12 and are formed continuously.
In the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c, electrode 7a, 7b of particulate generation device 7 expose configuration.Electrode 7a and electrode 7b is configured to respectively be separated by next door 10d in the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c.
Apply in AC wave shape or the voltage of impulse waveform to electrode 7a, 7b.Apply positive voltage to electrode 7a, the moisture of ion in air utilizing ionization to produce is combined, primarily of H +(H 2o) electric charge that m is formed forms positive cluster ion.Apply negative voltage to electrode 7b, the moisture of ion in air utilizing ionization to produce is combined, primarily of O 2 -(H 2o) electric charge that n is formed forms negative cluster ion.Wherein, m, n are random natural number.
H +(H 2o) m and O 2 -(H 2o) n condenses on the surface of aerial flcating germ and smell component, and they is surrounded.Further, as shown in formula (1) ~ (3), " OH " (hydroxyl radical free radical) and H of colliding and making as active group is utilized 2o 2they destroy by the surface that (hydrogen peroxide) cohesion is created on flcating germ and smell component etc.Wherein, m ', n ' are random natural number.Therefore, by producing cation and anion and they being sent from the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c, sterilization and deodorizing can be carried out to indoor.

In the micro-particle diffusing device 1 of said structure, if drive fan 8 and particulate generation device 7, then the air of indoor is drawn in casing 2 from suction inlet 5.After the air be drawn in casing 2 is filtered dust by filter 6, circulate in air-supply path 10 and be directed to fan 8.
The exhaust of fan 8 to the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation 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.Now, if the turning cylinder vertical configuration of fan 8, then make the air-flow on left and right directions uneven because of centrifugal force.Therefore, by the turning cylinder of horizontal arrangement fan 8, the uniform stream of left and right directions can be made.Further, because the sidewall 10e inside the first segmentation path 10 a and the 3rd segmentation path 10 c tilts relative to vertical guide, so can easily make to turn to from the air-flow of fan 8 circumferentially tangential direction straight ahead.
In addition, flow channel in the vertical direction expansion section 11 broadens along the vertical direction, and flow channel broadens in left-right direction in axial expansion section 12.Leaning in upstream vertical direction expansion section 11 than axial expansion section 12, the centrifugal forces affect to the fan 8 of circumferencial direction exhaust is larger.Therefore, in order to make air-flow advance towards the direction vertical with fan 8 turning cylinder, do not wish that left and right broadens.Further, by making flow channel broaden along the vertical direction expansion section 11 in the vertical direction, reclaiming the kinetic energy of air-flow and converting static pressure to, thus improve static pressure.Thus, the draft capacity of micro-particle diffusing device 1 can be improved.In addition, expansion section 11 can make the width of flow channel left and right directions fix in the vertical direction, and it also can be made to reduce slightly.Now, flow channel area expands gradually towards downstream.
In axial expansion section 12, due under the state that dies down at the centrifugal force produced by fan 8, flow channel expands in left-right direction, so the pressure loss can not be made to become large, thus turns to and broadens in left-right direction with can making airflow smooth.In addition, because flow channel narrows along the vertical direction, so air-flow can be made more to broaden in left-right direction swimmingly, and air velocity can be suppressed to decline.Now, because the flow channel area of axial expansion section 12 expands gradually towards downstream, so in axial expansion section 12, also can reclaim kinetic energy to convert static pressure to, thus can static pressure be improved.In addition, the width of flow channel above-below direction can be made in axial expansion section 12 to keep fixing, flow channel area also can be made to keep fixing.
Utilize particulate generation device 7, make in the air-flow of circulation in the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c containing cation and anion.Thus, the air-flow containing cation and anion is sent from the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c.
Fig. 6 represents the state of the air-flow of the indoor D sent from micro-particle diffusing device 1.The the first air-flow A1 sent to the right from the first blow-off outlet 4a circulates along roof T, and declines along the sidewall (the first wall P1) of right.The the second air-flow A2 forwards sent from the second blow-off outlet 4b circulates along roof T, and declines along the sidewall (the second wall P2) right with the sidewall S-phase being configured with micro-particle diffusing device 1.The 3rd air-flow A3 sent to the left from the 3rd blow-off outlet 4c circulates along roof T, and declines along the sidewall (the 3rd wall P3) of left.
The air-flow declined along the first wall P1, the second wall P2 and the 3rd wall P3 circulates on the ground F of indoor, and rear along sidewall S rising, to return micro-particle diffusing device 1 suction inlet 5.Thus, air-flow can be made along indoor each wall circulation and by ion diffuse each corner to indoor.In addition, utilize the air-flow along wall circulation, make ion gently be diffused into the living space of indoor central portion.Because first, second, third air-flow A1, A2, A3 utilizes wall attachment effect to advance along wall, so kinetic energy can be suppressed to be weakened by the air of indoor.Thus, can power consumption be suppressed, and the arrival distance of air-flow can be made to become large.
In addition, can switch by the polarity of the ion of electrode 7a, 7b generation every specified time limit.That is, produce cation from electrode 7a and produce anion from electrode 7b.If through specified time limit, then produce anion from electrode 7a and produce cation from electrode 7b.If again through specified time limit, then produce cation from electrode 7a and produce anion from electrode 7b, and repeating above-mentioned action.
Thus, make the first segmentation path 10 a, left end that the second segmentation path 10 b and the 3rd segmentation path 10 about c broadens the air-flow sent and right-hand member alternately send cation and anion.Therefore, cation and anion can be made to be distributed to the broad range of left and right directions in room with high concentration.
According to present embodiment, there is 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 in the horizontal direction, the first air-flow A1 is sent from the first blow-off outlet 4a, this first air-flow A1 circulates along roof T and declines along the first wall P1, the second air-flow A2 is sent from the second blow-off outlet, this second air-flow A2 circulates along roof T and declines along the second wall P2 right with sidewall S-phase, and send the 3rd air-flow A3 from the 3rd blow-off outlet 4c, the 3rd air-flow A3 circulates along roof T and declines along the 3rd wall P3 relative with the first wall P1.
Thus, first, second, third air-flow A1, A2, A3 utilizes wall attachment effect to advance along wall, so inhibit kinetic energy to be weakened by the air of indoor.That is, when air-flow does not flow along roof T, the upside of air-flow guides surrounding air (air between roof T and air-flow), and kinetic energy is weakened by surrounding air and loses.When air-flow flows along roof T, although make kinetic energy rejection because of the frictional resistance of wall, usually very little compared with the kinetic energy do not lost when roof T flows with air-flow.In the air conditioner in the past that above-mentioned patent document 2 is recorded, owing to not making air-flow flow along roof T, so kinetic energy is weakened by surrounding air, the arrival distance of air-flow correspondingly shortens.
Therefore, present embodiment can make the arrival distance of air-flow become large, and ion diffuse can be made to arrive each indoor corner.Therefore, can power saving be realized, and due to air-flow can not be provided directly to living space, so the uncomfortable sensation of user can be reduced, and make ion be diffused into indoor fully.
In addition, due to the turning cylinder horizontal arrangement of the fan 8 that centrifugal fan or axial-flow fan are formed, and path 10 of blowing has the first segmentation path 10 a, second segmentation path 10 b and the 3rd segmentation path 10 c of segmentation in the downstream of fan, and the sidewall 10e inside the first segmentation path 10 a and the 3rd segmentation path 10 c tilts relative to vertical guide, so air-flow can be made even in the lateral direction, and the air-flow of circumferentially tangential direction straight ahead can be easily made to turn to.
In addition, vertical direction expansion section 11 makes flow channel expand gradually along the vertical direction of fan 8 turning cylinder, and axial expansion section 12 makes downstream axially the expanding gradually and vertically reducing gradually along fan 8 turning cylinder of flow channel expansion section 11 in the vertical direction.Thus, can prevent the centrifugal force because of fan 8 from causing mass flow discrepancy even, and air-flow can be made to broaden along the axis of fan 8 turning cylinder.
Further, due to vertical direction expansion section 11 place in fan 8 downstream, flow channel area can not reduce, so can fully reclaim the kinetic energy of air-flow and improve static pressure.After this, inhibit the speed of air-flow decline and air-flow is broadened vertically at axial expansion section 12 place.Thus, the arrival distance not making the rotating speed of fan 8 accelerate just can to make air-flow becomes large.Therefore, power saving and the low noise of micro-particle diffusing device 1 can be realized, and ion can be made to be diffused into indoor fully.
In addition, expansion section 11 place in the vertical direction, the impact of the centrifugal force of fan 8 is comparatively large, even if the width of flow channel left and right directions broadens gradually, the effect broadened about air-flow also can decline, and likely makes the hydraulic performance decline of fan 8.Therefore, expansion section 11 place can make the width of flow channel left and right directions keep fixing in the vertical direction, and it also can be made to reduce slightly.In addition, the width of flow channel above-below direction can be made to keep fixing at axial expansion section 12 place.
In addition, because the flow channel area of axial expansion section 12 more more expands towards downstream, so in axial expansion section 12, also can reclaim kinetic energy to convert static pressure to, thus improve static pressure further.In addition, flow channel area also can be made to keep fixing at axial expansion section 12 place.Now, although the recover kinetic energy of axial expansion section 12 declines, utilize vertical direction expansion section 11 to reclaim kinetic energy, compared with the pastly can improve static pressure.
In addition, because multiple first segmentation path 10 a, the second segmentation path 10 b are connected with axial expansion section 12 with vertical direction expansion section 11 with the 3rd segmentation path 10 c, and split along the axis of fan 8, so air-flow is along the wall circulation of the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c, thus air-flow can be made to broaden swimmingly along the axis of fan 8.
In addition, casing 2 is also configured near indoor roof T by the turning cylinder horizontal arrangement of fan 8, and the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c are formed in the upper end of casing 2 and send air-flow along roof T.Thus, the air-flow sent along roof T utilizes wall attachment effect to circulate along roof T.Therefore, the arrival of air-flow can be made further apart from elongated.
Then, Fig. 7 represents the cross-sectional side view of the micro-particle diffusing device of the second embodiment.For convenience of explanation, same with the first embodiment shown in described Fig. 1 ~ Fig. 6 part adopts identical Reference numeral.In present embodiment, the first blow-off outlet 4a that horizontal alignment is arranged in the same manner as the first embodiment, the second blow-off outlet 4b and the 3rd blow-off outlet 4c are at the bottom front surface opening of casing 2.In addition, suction inlet 5 is in the upper surface open of casing 2.Other parts are identical with the first embodiment.
There is between the casing 2 of micro-particle diffusing device 1 and roof T the gap H of regulation, and be installed on an indoor sidewall S.First segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c (with reference to Fig. 4) tilt with predetermined angular upward relative to horizontal direction.Thus, the first air-flow A1, the second air-flow A2 and the 3rd air-flow A3 circulate along roof T after arriving roof T.
The the first air-flow A1 sent to the right from the first blow-off outlet 4a circulates along roof T, and declines along the sidewall (the first wall P1 (with reference to Fig. 6)) of right.The the second air-flow A2 forwards sent from the second blow-off outlet 4b circulates along roof T, and declines along the sidewall (the second wall P2 (with reference to Fig. 6)) right with the sidewall S-phase being configured with micro-particle diffusing device 1.The 3rd air-flow A3 sent to the left from the 3rd blow-off outlet 4c circulates along roof T, and declines along the sidewall (the 3rd wall P3 (with reference to Fig. 6)) of left.Further, the air-flow declined along the first wall P1, the second wall P2 and the 3rd wall P3 circulates on the ground F of indoor, and after rising along sidewall S, returns suction inlet 5 from the side of micro-particle diffusing device 1.
According to present embodiment, identical with the first embodiment, because first, second, third air-flow A1, A2, A3 utilizes wall attachment effect to advance along wall, so kinetic energy can be suppressed to be weakened by room air.Therefore, the arrival distance of air-flow can be made to become large, and ion diffuse can be made to arrive each indoor corner.Therefore, can power saving be realized, and due to air-flow can not be provided directly to living space, so the uncomfortable sensation of user can be reduced, and ion can be made to be diffused into indoor fully.
In addition, the gap H that the micro-particle diffusing device 1 of the first embodiment specifies apart from roof T can be made, and be arranged on sidewall S.Further, identical with present embodiment, make the first segmentation path 10 a, second split path 10 b and the 3rd segmentation path 10 c and tilt upward with predetermined angular relative to horizontal direction.Thus, can make the first air-flow A1, the second air-flow A2 and the 3rd air-flow A3 after arrival roof T, circulate along roof T.

The 4th air-flow A4 sent from the 4th blow-off outlet 4d declines along sidewall S.Now, the flow of the 4th air-flow A4 is less than the flow of the second air-flow A2, such as, be about 10% or less than 10% of the second air-flow A2 flow.Because first, second, third air-flow A1, A2, A3 returns suction inlet 5, so there is the situation of the ion deficiency near sidewall S in whole indoor circulation.Therefore, the 4th air-flow A4 declines along sidewall S and carrys out the ion of supplementary adjacent sidewalls, and returns suction inlet 5 together with first, second, third air-flow A1, A2, the A3 risen along sidewall S.
According to present embodiment, owing to having the 4th blow-off outlet 4d, and flow, so the ion near sidewall S can be supplemented from the 4th air-flow A4 that the 4th blow-off outlet 4d sends along the sidewall S being configured with micro-particle diffusing device 1.Now, relative to first, second, third air-flow A1, A2, the A3 returning suction inlet 5, the 4th air-flow A4 becomes resistance.But the flow due to the 4th air-flow A4 is less than the flow of the second air-flow A2, so the resistance produced by the 4th air-flow A4 can be suppressed.In addition, also the 4th blow-off outlet 4d can be set in the second embodiment shown in described Fig. 7.
Then, Fig. 9 represents the cross-sectional side view of the micro-particle diffusing device of the 4th embodiment.For convenience of explanation, identical with the first embodiment shown in described Fig. 1 ~ Fig. 6 part adopts identical Reference numeral.Present embodiment makes second segmentation path 10 b further shunt in front end.Other parts are identical with the first embodiment.

Figure 13, Figure 14 represent the cross-sectional side view of the D-D section of Figure 12 and the cross-sectional side view of E-E section.The fan 30 that cross flow fan (axial-flow fan) is formed is configured with in casing 2.Fan 30 covers the impeller 33 of cross-flow type by the first shell 31 and second housing 32.
Impeller 33 is driven by fan motor 33a (with reference to Figure 10) and rotates, turning cylinder horizontal arrangement.Utilize the driving of fan motor 33a, fan 30 is from the circumferencial direction air-breathing of impeller 33 and be vented to circumferencial direction.First shell 31 and second housing 32 are set up in parallel along the axis of impeller 33, at the both sides of the first shell 31 configuration second housing 32.
The first air-supply path 10 from the first suction inlet 5a leaked-in air circulation and the second air-supply path 20 from the second suction inlet 5b leaked-in air circulation is provided with in casing 2.The air flow passage in impeller 33 downstream in the first air-supply path 10 is formed by the first shell 31, and the air flow passage in impeller 33 downstream in the second air-supply path 20 is formed by second housing 32.
Offer the first suction side opening portion 31a in one end of the first shell 31, about half cycle of impeller 33 is from the outstanding configuration of the first suction side opening portion 31a.Near the first suction side opening portion 31a, the gap between impeller 33 and the first shell 31 is formed as minimum.The flow channel area of impeller 33 upstream side in the first air-supply path 10 is greater than the first suction side opening portion 31a.The wall of the first shell 31 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 in 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.
Offer the second suction side opening portion 32a in one end of second housing 32, about half cycle of impeller 33 is from the outstanding configuration of the second suction side opening portion 32a.Near the second suction side opening portion 32a, the gap between impeller 33 and second housing 32 is formed as minimum.The flow channel area of impeller 33 upstream side in the second air-supply path 20 is greater than the second suction side opening portion 32a.The wall of second housing 32 with the curvature bending of regulation, and offers the 4th blow-off outlet 4d in its front end.Thus, the second air-supply path 20 of connection the 4th blow-off outlet 4d and the second suction inlet 5b is formed.
In addition, from end on observation, near the first suction side opening portion 31a of the first shell 31, make prescribed limit consistent around the shape of rotating after the angle θ that center rotating specifies with the second suction side opening portion 32a from second housing 32.Thus, the opening surface of the first suction side opening portion 31a is configured to different angles in a circumferential direction from the opening surface of the second suction side opening portion 32a.
Therefore, the first shell 31 and second housing 32 can be made to be formed at optimum shape the fan 30 that cross flow fan formed, and to form the flow channel of the exhaust side in the first air-supply path 10 and the second air-supply path 20.Thus, in the first air-supply path 10 and the second air-supply path 20, the air-flow of circulation can not sharply turn to, and can reduce the pressure loss and improve air-supply efficiency, and can reduce noise.
Figure 15 represents the cross sectional top view of the C-C section of Figure 12.In the downstream of fan 30, be disposed with multiple the first segmentation path 10 a, the second segmentation path 10 b and the 3rd split in the horizontal direction and split path 10 c in the first air-supply path 10.First segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c offer the first blow-off outlet 4a, the second blow-off outlet 4b and the 3rd blow-off outlet 4c respectively in front end.In addition, the sidewall 10e inside the first segmentation path 10 a and the 3rd segmentation path 10 c and the sidewall 10f in outside is by the Surface forming tilted relative to vertical guide.
In the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation 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 expand gradually along the vertical direction of fan 30 turning cylinder.The downstream of expansion section 11 in the vertical direction, axial expansion section 12 makes flow channel axially expanding gradually and vertically reducing gradually along fan 30 turning cylinder.In addition, axial expansion section 12 tilts with predetermined angular upward relative to horizontal direction.
In addition, the flow channel area of axial expansion section 12 more more expands towards downstream.In addition, the first segmentation path 10 a, the second segmentation path 10 b and the 3rd are split path 10 c and vertical direction expansion section 11 and axial expansion section 12 and are formed continuously.
In the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c, electrode 7a, 7b of particulate generation device 7 same as described above expose configuration.Electrode 7a and electrode 7b is configured to respectively be separated by next door 10d in the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c.In addition, as shown in aforementioned Figure 13, in the second air-supply path 20, electrode 7a, 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 the air of indoor is drawn in casing 2 from the first suction inlet 5a and the second suction inlet 5b.After the air be drawn in casing 2 is filtered dust by filter 6, circulate in the first air-supply path 10 and the second air-supply path 20 and be directed to fan 30.
In the second housing 32 in the second air-supply path 20, the air-flow of circulation blows out from the 4th blow-off outlet 4d to the back lower place.Further, flow down along the sidewall S being provided with micro-particle diffusing device 1.
The air-flow of circulation in first shell 31 in the first air-supply path 10, to the first segmentation path 10 a, the second segmentation path 10 b and the 3rd segmentation path 10 c shunting.Further, 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.Now, if the turning cylinder vertical configuration of fan 30, then because centrifugal force makes the air-flow on left and right directions uneven.Therefore, by making the turning cylinder horizontal arrangement of fan 30, the uniform stream of left and right directions can be made.Further, because the sidewall 10e inside the first segmentation path 10 a and the 3rd segmentation path 10 c tilts relative to vertical guide, so can easily make to turn to from the air-flow of fan 30 circumferentially tangential direction straight ahead.
In addition, flow channel in the vertical direction expansion section 11 broadens along the vertical direction, and flow channel broadens in left-right direction in axial expansion section 12.Leaning in upstream vertical direction expansion section 11 than axial expansion section 12, the impact to the centrifugal force of the fan 30 of circumferencial direction exhaust is larger.Therefore, in order to make air-flow advance towards the direction vertical with fan 30 turning cylinder, do not wish that left and right broadens.By making flow channel expand along the vertical direction expansion section 11 in the vertical direction, reclaiming the kinetic energy of air-flow and being converted to static pressure, thus improve static pressure.Thus, the draft capacity of micro-particle diffusing device 1 can be improved.In addition, can expansion section 11 place be fixed by the width of flow channel left and right directions in the vertical direction, it also can be made to reduce slightly.Now, flow channel area expands gradually towards downstream.
In axial expansion section 12, due under the state that the centrifugal force produced at fan 30 dies down, flow channel expands in left-right direction, so the pressure loss can not be made to become large, thus turns to and broadens in left-right direction with can making airflow smooth.In addition, because flow channel narrows along the vertical direction, so air-flow can be made more to broaden in left-right direction swimmingly, and air velocity can be suppressed to decline.Now, because the flow channel area of axial expansion section 12 expands gradually towards downstream, so in axial expansion section 12, also can reclaim kinetic energy to convert static pressure to, thus improve static pressure.In addition, the width of flow channel above-below direction can be made in axial expansion section 12 to keep fixing, flow channel area also can be made to keep fixing.
Utilize particulate generation device 7, make in the air-flow of circulation in the first air-supply path 10 and the second air-supply path 20 containing cation and anion.Thus, the air-flow containing cation and anion is sent 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.
Figure 16 represents the state of the air-flow of the indoor D sent from micro-particle diffusing device 1.The the first air-flow A1 sent to the right from the first blow-off outlet 4a circulates along roof T, and declines along the sidewall (the first wall P1) of right.The the second air-flow A2 forwards sent from the second blow-off outlet 4b circulates along roof T, and declines along the sidewall (the second wall P2) right with the sidewall S-phase being configured with micro-particle diffusing device 1.The 3rd air-flow A3 sent to the left from the 3rd blow-off outlet 4c circulates along roof T, and declines along the sidewall (the 3rd wall P3) of left.
The 4th air-flow A4 sent from the 4th blow-off outlet 4d declines along the sidewall S being configured with micro-particle diffusing device 1.Now, the flow of the 4th air-flow A4 is less than the flow of the second air-flow A2, such as, be about 10% of the second air-flow A2 flow.
The air-flow declined along the first wall P1, the second wall P2 and the 3rd wall P3 circulates on the ground F of indoor, and the first rear along sidewall S rising, to return micro-particle diffusing device 1 suction inlet 5a.In addition, indoor portion of air returns the second suction inlet 5b from the top of micro-particle diffusing device 1.Thus, air-flow can be made along indoor each wall circulation and by ion diffuse each corner to indoor.In addition, utilize the air-flow along wall circulation, make ion gently be diffused into the living space of indoor central portion.Because first, second, third air-flow A1, A2, A3 utilizes wall attachment effect to advance along wall, so kinetic energy can be suppressed to be weakened by the air of indoor.
That is, when air-flow does not flow along roof T, the upside of air-flow guides surrounding air (air between roof T and air-flow), and kinetic energy is weakened by surrounding air and loses.When air-flow flows along roof T, although make kinetic energy rejection because of the frictional resistance of wall, usually very little compared with the kinetic energy do not lost when roof T flows with air-flow.Thus, power consumption can be suppressed and the arrival distance of air-flow can be made to become large.
In addition, because first, second, third air-flow A1, A2, A3 returns the first suction inlet 5a, so there is the situation of the ion deficiency near sidewall S in whole indoor circulation.Therefore, the 4th air-flow A4 declines along sidewall S, can supplement the ion of adjacent sidewalls.Now, the flow due to the 4th air-flow A4 is less than the flow of the second air-flow A2, so can suppress the resistance produced by the 4th air-flow A4.
In addition, because the axial expansion section 12 in the first air-supply path 10 tilts with predetermined angular upward relative to horizontal direction, so can make the first air-flow A1, the second air-flow A2 and the 3rd air-flow A3 after arrival roof T, circulate along roof T.But the first air-flow A1, the second air-flow A2 and the 3rd air-flow A3 are before arrival roof T, and kinetic energy is weakened.Therefore, in order to make the distance apart from roof T shorten, preferably gap H is set in below 30cm, and preferably makes the angle of inclination of the air-flow of circulation in axial expansion section 12 below 20 °, to flow along roof T with making airflow smooth.
In addition, can switch by the polarity of the ion of electrode 7a, 7b generation every specified time limit.That is, produce cation from electrode 7a and produce anion from electrode 7b.If through specified time limit, then produce anion from electrode 7a and produce cation from electrode 7b.If again through specified time limit, then produce cation from electrode 7a and produce anion from electrode 7b, and repeating above-mentioned action.
Thus, make the first segmentation path 10 a, left end that the second segmentation path 10 b and the 3rd segmentation path 10 about c broadens the air-flow sent and right-hand member alternately send cation and anion.Therefore, cation and anion can be made to be distributed to the broad range of left and right directions in room with high concentration.
According to present embodiment, because first, second shell 31,32 of the covering impeller 33 of fan 30 is set up in parallel along the axis of impeller 33, and the blow-off direction respectively flowing through air-flow is wherein different, so just can send air-flow to multiple directions by simple structure.Therefore, ion diffuse can be easily made to arrive each indoor corner.In addition, because air-flow can not sharply turn to, so can prevent the pressure loss from increasing, thus improve air-supply efficiency, and can noise be reduced.
In addition, first shell 31 at one end offers the first suction side opening portion 31a making impeller 33 outstanding, and extend to the exhaust side of impeller 33, second housing 32 at one end offers the second suction side opening portion 32a making impeller 33 outstanding, and extends to the exhaust side of impeller 33.Further, the opening surface of the first suction side opening portion 31a and the opening surface of the second suction side opening portion 32a are circumferentially configured to different angles at impeller 33.Thus, simply first, second shell 31,32 can be formed as the low optimum shape of the pressure loss relative to fan 30.In addition, easily the blow-off direction (back lower place) of the blow-off direction (front upper place) flowing through the air-flow of the first shell 31 and the air-flow that flows through second housing 32 can be formed as difference more than 90 °.
In addition, due to the end on observation from impeller 33, apart from the first shell 31 of the first suction side opening portion 31a prescribed limit, consistent with the shape of second housing 32 after the center of rotation of impeller 33 is rotated apart from the second suction side opening portion 32a prescribed limit, so first, second shell 31,32 of optimum shape can be formed more simply.
In addition, owing to utilizing the first shell 31 to send air-flow towards front upper place to indoor, and second housing 32 is utilized to send air-flow to indoor downward, so can easily make ion diffuse arrive each indoor corner.In addition, when gap H is less, the first shell 31 also can be utilized to horizontal direction blowout air-flow.
In addition, owing to utilizing the first shell 31 to send air-flow towards front upper place to indoor, and second housing 32 is utilized to send air-flow to indoor downward, so can easily make indoor air be circulated to each corner.In addition, when gap H is less, the first shell 31 also can be utilized to blow out air-flow in the horizontal direction.
Also can omit particulate generation device 7 in first ~ five embodiment, but adopt circulator, this circulator utilising first, second, third, fourth air-flow A1, A2, A3, A4 make indoor airflow circulating.Now, because first, second, third air-flow A1, A2, A3 utilizes wall attachment effect to advance along wall, so kinetic energy can be suppressed to be weakened by the air of indoor, thus the arrival distance of air-flow can be made to become large.Therefore, can power saving be realized, and due to air-flow can not be provided directly to living space, so the uncomfortable sensation of user can be reduced, and indoor air circulation can be made fully.
Then, Figure 17, Figure 18 represent stereogram and the cross-sectional side view of the micro-particle diffusing device of the 6th embodiment.For convenience of explanation, identical with the first embodiment shown in described Fig. 1 ~ Fig. 6 part adopts identical Reference numeral.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 installation surface abutted with the ground F of indoor, thus is placed on the F of ground by micro-particle diffusing device 1.In addition, micro-particle diffusing device 1 can be configured near the angle, room between a sidewall S and ground F.

In first, second blowout passage 42c, 52c, multiple electrodes (not shown) of particulate generation device 7 same as described above expose configuration.
In the micro-particle diffusing device 1 of said structure, if the motor 9 of drive fan 40 and particulate generation device 7, then the air of indoor is drawn in casing 2 from suction inlet 5.The air sucked in casing 2 passes through first, second air entry 42b, 52b, flows in first, second shell 42,52.The air flowing into first, second shell 42,52 is discharged from first, second cylindrical portion 42a, 52a to circumferencial direction, and circulates in first, second blowout passage 42c, 52c.The air circulated in first, second blowout passage 42c, 52c contains ion, and blows out towards the direction of arrow B 1, B2 respectively from first, second blow-off outlet 43,53.
Now, because the upstream portion 42d of flow channel at the first blowout passage 42c broadens along the direction vertical with turning cylinder 9a, so the kinetic energy of air-flow can be reclaimed and convert static pressure to, thus static pressure is improved.Thus, the draft capacity of fan 40 can be improved.In addition, because flow channel narrows, so the speed of air-flow can be suppressed to decline along the direction vertical with turning cylinder 9a at downstream portion 42e.Thus, air-flow at a high speed can be sent from the first blow-off outlet 43 that aperture area is less.
Therefore, from the first blow-off outlet 43 above vertical or back upper place blowout air rise along the sidewall S near micro-particle diffusing device 1.Further, above-mentioned air flows through roof, the sidewall relative with micro-particle diffusing device 1 and ground F, and returns micro-particle diffusing device 1.In addition, utilize the air-flow along wall circulation, make ion gently be diffused into the living space of indoor central portion.Thus, air-flow can be made along indoor each wall circulation, and make ion diffuse arrive each indoor corner.
Because the air-flow blown out from the first blow-off outlet 43 utilizes wall attachment effect to advance along wall, so inhibit kinetic energy to be weakened by the air of indoor.That is, when air-flow does not flow along wall, the side surface side of air-flow guides surrounding air (air between wall and air-flow), and kinetic energy is weakened by surrounding air and loses.When air-flow flows along wall, although make kinetic energy rejection because of the frictional resistance of wall, usually very little compared with the kinetic energy do not lost when wall flows with air-flow.Thus, power consumption can be suppressed and the arrival distance of air-flow can be made to become large.In addition, also can, at the downstream portion 42e place of the first blowout passage 42c, the width in the direction vertical with turning cylinder 9a of flow channel be made to keep fixing.
In addition, the second blowout passage 52c makes flow channel from the second cylindrical portion 52a to the second blow-off outlet 53, broadens along the direction vertical with turning cylinder 9a.Therefore, reclaim the kinetic energy of air-flow and convert static pressure to, thus improving static pressure.Thus, the draft capacity of micro-particle diffusing device 1 can be improved further.Further, the air-flow of low speed is sent from the second blow-off outlet 53 that aperture area is larger.
Utilize the air from the second blow-off outlet 53 forward upward blowout, the living space to indoor central portion supplements ion.In addition, because the air-flow blown out from the second blow-off outlet 53 is low speed, so can prevent because wind directly contacts the user of living space and cause uncomfortable sensation.
In addition, can switch by the polarity of the ion of each electrode generation of particulate generation device 7 every specified time limit.That is, produce cation from an electrode and produce anion from another electrode.If through specified time limit, then produce anion from an electrode and produce cation from another electrode.If again through specified time limit, then produce cation from an electrode and produce anion from another electrode, and repeating above-mentioned action.
Thus, cation and anion is alternately sent at the left end of air-flow and right-hand member.Therefore, cation and anion can be made to be distributed to the broad range of left and right directions in room with high concentration.
According to present embodiment, a motor 9 is utilized to drive first, second impeller 41,51 of arranged coaxial.And, first blowout passage 42c blows out the direction that passage 52c extends from the periphery of the second cylindrical portion 52a of covering second impeller 51 from the direction and second that the periphery of the first cylindrical portion 42a of covering first impeller 41 extends, different in a circumferential direction, different from the blow-off direction (B2) of the air-flow blown out from the second blow-off outlet 53 from the blow-off direction (B1) of the air-flow of the first blow-off outlet 43 blowout.Thus, just air-flow can be sent to multiple directions by simple structure.In addition, because air-flow can not sharply turn to, so can prevent the pressure loss from increasing, thus air-supply efficiency can be improved and reduce noise.
In addition, the aperture area due to the first blow-off outlet 43 is less than the aperture area of the second blow-off outlet 53, so the wind speed of the first blow-off outlet 43 can be made to be greater than the wind speed of the second blow-off outlet 53.Thus, the arrival distance of the air-flow that the first blow-off outlet 43 can be made to blow out becomes large.In addition, when the air-flow blown out by the second blow-off outlet 53 is sent to the living space of indoor, can prevent user from feeling uncomfortable.
In addition, the width due to the first square with the axis direction of blow-off outlet 43 is less than the width in the second square with the axis direction of blow-off outlet 53, so the wind speed of the first blow-off outlet 43 can be made simply to be greater than the wind speed of the second blow-off outlet 53.
In addition, the upstream portion 42d of the first blowout passage 42c makes flow channel expand gradually along square with the axis direction, and downstream portion 42e makes flow channel keep fixing along square with the axis direction or reduce gradually.Therefore, owing to making flow channel area narrow at the upstream portion 42c in the first impeller 41 downstream, so can fully reclaim the kinetic energy of air-flow and improve static pressure, thus air-supply efficiency can be improved.After this, suppress the speed of air-flow to decline at downstream portion 42e, and blow out air-flow from the first blow-off outlet 43 that aperture area is less than the second blow-off outlet 53.Thus, do not make the rotating speed of fan 40 accelerate, the arrival distance of the air-flow that the first blow-off outlet 43 just can be made to blow out becomes large.
Further, the second blowout passage 52c makes flow channel expand gradually along square with the axis direction, and blows out air-flow from the second blow-off outlet 53 that aperture area is larger.Thus, can fully reclaim the kinetic energy of air-flow and improve static pressure, thus air-supply efficiency can be improved, and easily can blow out the air-flow of low speed compared with the first blow-off outlet 43 from the second blow-off outlet 53.
In addition, by the first shell 42 from the first blow-off outlet 43 above vertical or back upper place send air-flow, and send air-flow by second housing 52 from the second blow-off outlet 53 forward upward.Therefore, if by near the angle, room of a sidewall S and ground F disposed in the interior for micro-particle diffusing device 1, then the high velocity air blown out from the first blow-off outlet 43 flows through this sidewall S, roof, relative sidewall and ground F.Therefore, ion can be made to be diffused into indoor fully.Further, from the second blow-off outlet 53 to the air-flow of the living space of indoor blowout low speed, thus the ion of living space can be supplemented, and can prevent user from feeling under the weather.
In addition, because first, second impeller 41,51 has blade 41b, 51b on two surfaces of plectane 41a, 51a, and first, second air entry 42b, 52b are separately positioned on two surfaces of first, second cylindrical portion 42a, 52a axis, so the small-sized and fan 40 that air quantity is larger easily can be obtained.
