Patent documentation 2: special hope 2002-206163 number
But, ion diffuser in the past, the arrival of jet is apart from weak point, and is unfavorable for that fluid is to carrying on a large scale.Therefore, possess the above-mentioned refrigerator of this ion diffuser, with respect to the generation of ion, the diffusivity of ion, promptly to have a diffusivity of fine particle of bactericidal action lower.
In Fig. 37, show in room temperature is 15 ℃ room, ion blow-off outlet 22 is to the indoor ion concentration of room each several part when emitting the cluster ion outside the refrigerator case of refrigerator 200 with ion diffuser 110a in the past.Wherein, confirmed that working as cation concentration is 2000/cm
3More than, and negative ion concentration is 2000/cm
3When above, bactericidal effect is arranged.
In Figure 37, though outside the refrigerator case ion blow-off outlet 22 around have the ion of high concentration, should the zone narrow, not necessarily enough.For example, the ion concentration of the 10mm position, the place ahead of the outer ion blow-off outlet 22 of refrigerator case is about 100,000/cm
3, produced enough ions from ion generating apparatus 14, but the ion that becomes high concentration is stuck near the state the blow-off outlet, and to the diffusion of whole room.
Again, enlarge the high zone of concentration of the fine particle of emitting, get final product, the problem that exists the air-supply noise obviously to increase like this though increase the rotating speed of pressure fan 12.Again, enlarge the high zone of concentration of the fine particle of emitting, though increasing the fine particle growing amount of fine particle generation device gets final product, but for example under the situation of above-mentioned ion generating apparatus, existing not only needs significantly to improve the voltage that is added on the ion generating apparatus 14, and ion produces sound and increases, and other problems such as increases with the produced simultaneously ozone amount of ion explosively.
Again, though on a lot of household appliances, carried the fine particle diffuser that as existing ion diffuser 110a, in air, spreads fine particle, with the above-mentioned the same low problem of diffusivity that all has fine particle.
The present invention makes in view of foregoing problems, the object of the present invention is to provide the arrival distance that can significantly prolong the fine particle that fine particle diffuser emits, and can carry fine particle on a large scale, can improve the effect of fine particle and reduce the fine particle diffuser of noise.And the object of the present invention is to provide refrigerator with this fine particle diffuser.
Summary of the invention
In order to achieve the above object, the invention is characterized in: air-supply passage gradually changes from the aspect ratio of starting point towards terminal point, cross section.Rate of change by suitable this aspect ratio of setting can suppress the velocity attenuation of the wind of emitting from blow-off outlet, thus can prolong the arrival distance of fine particle, and can carry fine particle on a large scale.
Again,, then can obtain the effect of diffuser, improve fine particle and send ability if the amplification degree of above-mentioned aspect ratio or the amplification degree of sectional area are chosen to be suitable value.
Again, the present invention, the aspect ratio AR in the cross section of the destination county by setting air-supply passage is 2≤AR≤20 or 5≤AR≤22, preferably is made as 5≤AR≤20, can suppress the wind speed decay of the jet sent from blow-off outlet, the arrival distance that can prolong fine particle.Therefore, can improve the concentration that is positioned at than the fine particle of distant positions.
And, by air-supply passage being designed to many passages or utilizing wind deflector to cut apart, can not be subjected to size restrictions and easily the aspect ratio of blow-off outlet is set at optimum value, and can evenly emit fine particle, can make uniform fine particle arrive a distant place from blow-off outlet.
In addition, the aspect ratio AR in the cross section at the starting point place of air-supply passage is preferably AR≤2.
Again, the present invention by wind direction alteration board is set near blow-off outlet, can utilizes simple structure to concentrate from the fine particle that the fine particle generation device is sent and emit to the direction of hope, or spread on a large scale.
Again, the present invention utilizes fairing that near the air that flows through the fine particle generation device is carried out rectification and reaches disorderly less state, can prevent that fine particle from producing decrease in efficiency, and reduces the probability that the fine particle that produced collides each other.For example, at the fine particle generation device is when roughly producing the ion generating apparatus of cation and anion equally, can prevent the cation that produces and anion owing to thereby collision loses the situation that electric charge is withered away, therefore, can prevent that the transfer efficiency of ion from descending.That is, rectification is carried out in disorder, can be prevented that fine particle from producing the decline of efficient or the decline of fine particle transfer efficiency by upstream side at configuration fine particle generation device.
Again, the present invention can utilize the section contraction flow region to turbulent rectification, can near the air that flow through the fine particle generation device be carried out rectification and reach disorderly less state.Therefore, do not use special device can realize and above-mentioned much the same effect.
Again, the present invention, if establishing the fine particle of fine particle generation device, to produce the width perpendicular to the direction that flows on the position be that the width of w1, the air-supply passage relative with fine particle generation position is w2, then by being set at 0.7 * w1≤w2≤1.3 * w1, be preferably set to w2=w1, can carry fine particle effectively, and make its diffusion.
Again, the present invention utilizes air cleaner to prevent oil smoke or dust intrusion fine particle diffuser inside, and can prevent dirt attached on the fine particle generation device, and the generation that suppresses fine particle reduces in time.
Again, the present invention because blow-off outlet is arranged on the refrigerator top, so fine particle can be diffused into fartherly, can enlarge the space that can kill the microorganisms such as planktonic bacteria that exist in the refrigerator surrounding space.Therefore, planktonic bacteria is invaded outside case in the case in the time of can further preventing to open and close, and realizes environment in the case of health more.
Again, the present invention because blow-off outlet is arranged on refrigerator front surface top, can concentrate the front face side that is diffused into refrigerator with the fine particle with bactericidal action.Therefore, planktonic bacteria is invaded outside case in the case in the time of can further preventing to open and close, and realizes environment in the case of health more.
Again, the present invention owing to respect to the horizontal plane emit fine particle downwards from blow-off outlet, can effectively scatter the fine particle with bactericidal action to the space outside the refrigerator case.Again, because the microorganisms such as planktonic bacteria that exist in the refrigerator surrounding space can accumulate in the bottom, space because of gravity sedimentation in time, so, can more effectively kill these microorganisms by with respect to the horizontal plane emitting ion downwards.Particularly be provided with on top or front surface top the fine particle with bactericidal action disperser, highly arrive for 1700mm under the situation of refrigerator of 1800mm, because can the fine particle with bactericidal action to be spread to apart from ground level effectively be the position of 1300mm to 1500mm, thus can effectively suppress the user by breathing with the situation in the microorganism suction bodies such as virus.
If according to the present invention, then can prolong the arrival distance of the fine particle (having the particulate of bactericidal action etc.) that fine particle diffuser emits significantly by setting the aspect ratio of blow-off outlet for the best, and can carry fine particle on a large scale, can improve the effect of fine particle and reduce noise.

The specific embodiment
Below, embodiments of the present invention are described with reference to the accompanying drawings.For convenience of explanation, the part same with example in the past adopts same Reference numeral, and part same in each embodiment or comparative example also adopts same Reference numeral.
＜the 1 embodiment 〉
The following describes the 1st embodiment.Fig. 1 is the summary top plan view of the fluid generating device of expression present embodiment, and Fig. 2 is the summary sectional side view of the fluid generating device of expression present embodiment.The fluid generating device 1a of present embodiment comprises: send fluids such as gas or liquid fluid supply apparatus 2, carry the fluid of sending from this fluid supply apparatus 2 fluid flow passage 3, be formed on the end of this fluid flow passage 3 and blow-off outlet 5 that fluid is sent with pattern, not shown control part.Fluid flows through fluid flow passage 3 by the driving of fluid supply apparatus 2 and be transferred, and becomes jet from blow-off outlet 5 and emits to the outside.Arrow among the figure is represented flowing of fluid.
Again, in the fluid flow passage 3, the upstream portion of blow-off outlet 5 is made of the 3b of enlarged tube portion, and along with towards blow-off outlet 5, the height of fluid reduces gradually and width increases gradually, becomes the formation that sectional area enlarges smoothly.Again, at fluid supply apparatus 2 tight rears, be the starting point of fluid flow passage 3, the cross sectional shape of the 3b of enlarged tube portion is set at height 45mm, width 45mm, i.e. aspect ratio: AR=1.And, at the terminal point of fluid flow passage 3, be blow-off outlet 5 places, be set at height 10mm, width 360mm, i.e. aspect ratio: AR=36.
At this, so-called aspect ratio is the length parameter ratio each other of decision cross sectional shape, is by aspect ratio: the value of AR=(long parameter)/(short parameter) decision.Therefore, when being rectangle, use aspect ratio in the cross section: AR=(long limit)/(minor face) expression, again, when the cross section is ellipse, use aspect ratio: AR=(major diameter)/(minor axis) expression.For example, when the cross section is square, aspect ratio: AR=1; When the ratio of long limit and minor face is 2: 1 a rectangle, aspect ratio: AR=2; The cross section is positive bowlder, aspect ratio: AR=1.Therefore, the aspect ratio in this specification etc. is got the value more than 1 usually.
And in the 3b of enlarged tube portion, the upstream portion a little from the tight downstream portion of fluid supply apparatus 2 to blow-off outlet 5 is provided with a plurality of guided plates 6, utilizes this guided plate 6 to be divided into a plurality of parts in the 3b of enlarged tube portion.In the present embodiment, the 3b of enlarged tube portion is divided into 4 parts by 3 guided plates 6, and each fluid flow passage 3 of zoning constitutes, and along with near blow-off outlet 5, aspect ratio increases, and is set at about AR=9 near the aspect ratio at the place, end of the guided plate 6 of blow-off outlet 5.Again, 3 guided plates 6 are arranged to, and make that the velocity flow profile longitudinally at blow-off outlet 5 places is all much the same anywhere.Therefore, the velocity flow profile longitudinally at blow-off outlet 5 tight rears is all roughly even in any part of blow-off outlet 5.
Fig. 3 be expression as the use-case that makes of fluid generating device 1a, sent and blown out flow velocity the figure of the velocity flow profile when being the air of 1.5m/s.Grid 1 lattice among the figure are represented 0.5m.In addition, even the fluid of sending from blow-off outlet 5 is a liquid, also show much the same tendency qualitatively.If with the making use-case (with reference to Figure 34) then can know discovery of the fluid generating device 100a of aftermentioned comparative example 1, as shown in Figure 3, the arrival of the fluid of sending from blow-off outlet 5 is apart from increase, and can be transported to large-scale zone by the fluid that flow velocity is big.
Below, the fluid generating device 100a of the fluid generating device 1a of present embodiment with respect to comparative example 1 is described, the principle that the ability of fluid generating device significantly improves.The flow velocity of jet is in the decay that will begin in a minute after blow-off outlet 5 blows out.The arrival distance of jet, relevant with potential core's length of jet.Fig. 4 is explanation potential core's a synoptic diagram.Generally, just the velocity flow profile of the jet central portion after blow-off outlet is sent is a homogeneous.The part of this speed homogeneous owing to the food of invading from the free mixed layer of both sides development reduces, disappears in certain distance.This part is a wedge-like, is called the potential core.Following situation is by known: for the free jet that flows out in stationary fluid, potential core's length is according to the blow-off outlet shape, along the state in the boundary layer of blow-off outlet wall, initial disorder etc. and different, but for 2 dimension turbulent jets, be blow-off outlet height or diameter about 5～7 times, for the axial symmetry turbulent jet, be blow-off outlet height or diameter about 5～8 times.Elongated along with this potential core's length, the arrival of jet is apart from prolongation.
In the fluid generating device 1a of present embodiment, the potential core's length that prolongs jet by aspect ratio optimization with blow-off outlet 5, thus suppress the decay of flow velocity, so comparing with prior art (comparative example 1) significantly, the arrival of fluid distance prolongs.For example, then such as already described if establish certain, the transverse width endless of the height of blow-off outlet 5, become 2 dimension turbulent jets, potential core's length is blow-off outlet height or diameter about 5～7 times.Again, then the same with the axial symmetry turbulent jet if establish the height of blow-off outlet identical with transverse width (AR=1), potential core's length is blow-off outlet height and blow-off outlet transverse width about 5～8 times.If aspect ratio optimization with blow-off outlet 5, for example suitably set transverse width with respect to the height of blow-off outlet 5, then potential core's length not only is subjected to the blow-off outlet height also to be subjected to the influence of blow-off outlet transverse width, so potential core's length is about 5～8 times of mean value of blow-off outlet height and the width, the 2 dimension turbulent jets during with identical blow-off outlet height or the situations of axial symmetry turbulent flow are compared significant prolongation.
Fig. 5 and Fig. 6 are among the fluid generating device 1a of expression present embodiment, the figure that concerns between near the aspect ratio in the cross section the blow-off outlet 5 and the potential core's length.■ symbol among Fig. 5 be fixedly blow out flow velocity, blow out flow, the potential core's length when blow-off outlet area and potential core's length when changing aspect ratio (blow-off outlet width/blow-off outlet height) are 1 (blow-off outlet is a square) divided by aspect ratio and nondimensionalization value.The value that zero symbol is is potential core's length of 1 o'clock and nondimensionalization according to potential core's length of blow-off outlet height prediction divided by aspect ratio.The value that the ◇ symbol is is potential core's length of 1 o'clock and nondimensionalization according to potential core's length of the mean value of blow-off outlet height and width prediction divided by aspect ratio.
According to Fig. 5, actual potential core's length, the approaching value of predicting according to the mean value of blow-off outlet height and width before about aspect ratio to 5, when aspect ratio becomes 2 dimension turbulent jets when above and near the value according to the prediction of blow-off outlet height 30, in aspect ratio is 5～30 zone, show the characteristic between aforementioned 2 predicted values of level and smooth binding.According to Fig. 5, aspect ratio more than 2 then dimensionless potential core length to be better than aspect ratio be 1 o'clock, aspect ratio is in then lose ground more than 20 (2≤AR≤20).
The ■ symbol of Fig. 6, be fixedly blow out flow velocity, blow-off outlet height and potential core's length when changing aspect ratio when being 1 (blow-off outlet is a square) divided by aspect ratio potential core's length and nondimensionalization value.In this case, along with aspect ratio increases, blow-off outlet area and blow out flow and increase.According to Fig. 6 as can be known, from dimensionless potential core length, aspect ratio is then becoming 2 dimension turbulent jets more than 30.Again, aspect ratio more than 1 then dimensionless potential core length to be better than aspect ratio be 1 o'clock, aspect ratio is then being lost ground more than 30.What show more obvious advantage is dimensionless potential core length 3 when above, and the aspect ratio of this moment is 5≤AR≤22.
Therefore, satisfy the scope (2≤AR≤20) of the aspect ratio that derives from Fig. 5 simultaneously and the scope of 5≤AR≤20 of the scope (5≤AR≤22) of the aspect ratio that derives from Fig. 6 is only aspect ratio.In addition, the characteristic of Fig. 5, Fig. 6, also sometimes according to the kind (physical characteristic) of fluid, blow-off outlet shape, along the difference of the state in the boundary layer of blow-off outlet wall, initial disorder etc., and the value of causing or characteristic are slightly different.
That is,, be same traffic, then be set to the best and can prolong potential core's length, be i.e. the arrival distance of fluid by aspect ratio with blow-off outlet 5 if blow-off outlet area and blow-off outlet flow velocity are identical.In other words, in potential core's length, be the arrival distance of fluid when identical, can reduce flow, so can reduce the consumption electric power and the level of noise of fluid supply apparatus 2.

＜the 6 embodiment 〉
The following describes the 6th embodiment.Figure 14 is the summary top plan view of ion diffuser of expression present embodiment, and Figure 15 is the summary sectional side view of the ion diffuser of expression present embodiment, and Figure 16 is the front view of the refrigerator of the ion diffuser of expression with present embodiment.
The ion diffuser 11a of present embodiment comprises: pressure fan 12, air-supply passage 13, the ion generating apparatus 14 that is provided with towards the mode of air-supply passage 13 with discharge face 14a, not shown control part.The ion that utilizes the driving of ion generating apparatus 14 to produce is transferred by the driving of pressure fan 12, flows through air-supply passage 13 and emits to the outside from disperser blow-off outlet 15.In addition, the arrow among Figure 14 and Figure 15 is represented the situation of the air-flow of this moment.

As described above, by cation and anion being released to case around the refrigerator 20a the place ahead space of living outward, and kill the planktonic bacteria that exists in this living space, the living space of health is provided, and planktonic bacteria is invaded outside case in the case when preventing shutter door 21 switchings, can realize the interior environment of case of health.
Again, air-supply passage 13 has section contraction flow region 13a and the 13b of enlarged tube portion.From pressure fan 12 towards the air-supply passage 13 of disperser blow-off outlet 15, section contraction flow region 13a is arranged on tight the place ahead of discharge face 14a of ion generating apparatus 14, and the sectional area of the air-supply passage 13 that is communicated with from pressure fan 12 presents the shape that reduces smoothly along with near the discharge face 14a of ion generating apparatus 14 at section contraction flow region 13a.Utilize this section contraction flow region 13a that rectification is carried out near the disorder of the air the discharge face 14a that flows through ion generating apparatus 14, and can suppress the deflection that flows that pressure fan 12 downstreams produce, be so-called bias current.
And, be w1 if establish the width of the discharge face 14a of ion generating apparatus 14 perpendicular to the direction that flows, be w2 towards the width of the air-supply passage 13 of discharge face 14a, then set w2=w1.Therefore, the ion concentration in the air-supply passage 13 of ion generating apparatus 14 downstream portions is roughly even in perpendicular to the plane of flow direction.
At this,, then on perpendicular to the direction that flows, produce the discrete of ion concentration, so undesirable if set w2＞1.3 * w1.Particularly the discharge face 14a that makes ion generating apparatus 14 perpendicular to the central authorities of the direction that flows when being in same position towards the central consistent of the air-supply passage 13 of discharge face 14a, ion is the ion concentration height near the central authorities of disperser blow-off outlet 15, and place, two ends ion concentration is low.Again, make discharge face 14a partially by the one-sided structure of air-supply passage 13 if be made as, then, low in the opposite side ion concentration only at the one-sided ion concentration height of disperser blow-off outlet 15.
Again, if establish w2＜0.7 * w1, then the ion of emitting from discharge face 14a can not be stated from the air-flow rather than effectively.Therefore,, preferably be made as w2=w1, can carry ion effectively and make its diffusion by being set at 0.7 * w1≤w2≤1.3 * w1.
Again, 15 part is made of the 13b of enlarged tube portion from ion generating apparatus 14 to the disperser blow-off outlet, constitutes along with from from the structure that enlarges smoothly towards disperser blow-off outlet 15, sectional area in generation device 14.Again, the cross sectional shape of the 13b of enlarged tube portion at ion generating apparatus 14 tight rears is set at, height 10mm, width 30mm, i.e. aspect ratio: AR=3; At the terminal point of the 13b of enlarged tube portion, be disperser blow-off outlet 15 places, be set at height 8mm, width 450mm, i.e. aspect ratio: AR=56.
And, in the 13b of enlarged tube portion, be provided with a plurality of wind deflectors 16 a little upstream portion from the tight downstream portion of ion generating apparatus 14 to disperser blow-off outlet 15, utilize this wind deflector 16 that the inside of the 13b of enlarged tube portion is divided into a plurality of parts.The 13b of enlarged tube portion is divided into 7 parts by 6 wind deflectors 16 in the present embodiment, aspect ratio becomes big to each air-supply passage 13 that zoning is opened along with close disperser blow-off outlet 15, and the aspect ratio at close disperser blow-off outlet 15 1 sides' of wind deflector 16 place, end is set in about 8.Again, 6 wind deflectors 16 are set at, and make that the wind speed profile longitudinally at disperser blow-off outlet 15 places is all roughly the same anywhere.Therefore, the ion concentration of disperser blow-off outlet 15 downstream portions is roughly even in perpendicular to the plane of flow direction.
Again, the 13b of enlarged tube portion is along with downward-sloping near disperser blow-off outlet 15.That is, ion ion blow-off outlet 22 outside the refrigerator case is with respect to the horizontal plane sent downwards.In the present embodiment, the outer ion blow-off outlet 22 of refrigerator case is arranged on overhead about 1700mm place, so by with respect to the horizontal plane sending ion downwards, ion effectively can be spread in the outer space of refrigerator case.Again, be present in the microorganisms such as planktonic bacteria in the refrigerator space on every side, the sedimentation in time owing to gravity, savings is in the bottom, space, so by with respect to the horizontal plane sending ion downwards, can more effectively kill these microorganisms.Particularly under the situation of present embodiment, ion can be spread to effectively overhead height and be 1300mm to the position of 1500mm, so can effectively prevent the user from passing through to breathe with in the microorganism suction bodies such as virus.

mIon, the ion concentration of room each several part when being so-called cluster ion.Figure 18 is the figure that the position between the measurement point of refrigerator and indoor ion concentration distribution of expression present embodiment concerns.The size in room is 8 close sizes of couch couch (height 2400mm, width 3600mm, depth 3600mm), and measurement point is that the height apart from ground, room is the cross section of 1700mm shown in single-point line among Figure 18.Again, the wind speed of the outer ion blow-off outlet 22 of refrigerator case this moment all is roughly uniform 1.5mm/s in any longitudinally position of blow-off outlet, and the arrow of Figure 18 is represented the state of air-flow this moment.And this moment, the level of noise at 1m place, refrigerator the place ahead was 22dB.
In addition, when cation concentration be 2000/cm
3More than, and negative ion concentration is 2000/cm
3When above, confirm to have above-mentioned bactericidal effect.
According to Figure 17, the ion that ion blow-off outlet 22 blows out outside the refrigerator case has arrived the end in room, and this point relatively shows clearly with the ion diffuser 110a of aftermentioned comparative example 2.Again, the ion concentration of the outer 10mm position, ion blow-off outlet 22 the place ahead of the refrigerator case of present embodiment is about 10,000/cm
3, can as comparative example 2, not be stuck near the blow-off outlet by the ion of high concentration yet.And as can be known, demonstrating cation concentration in about zone more than 60% in the room of 8 close sizes of couch couch is 2000/cm
3More than and negative ion concentration be 2000/cm
3Above ion concentration, the zone that shows bactericidal effect is much bigger than comparative example 2.
Below, the principle that the ions diffusion ability of ion diffuser 11a of present embodiment significantly improves with respect to the ion diffuser 110a of comparative example 2 is described.The 1st, the 13b of enlarged tube portion is designed to have the effect of diffuser, therefore, the kinetic energy of air-flow can be converted into static pressure, can assist the draft capacity of pressure fan 12, so with not shown air cleaner, section contraction flow region 13a, and other air-supply passages 13 in pressure losses of producing compare air output when all being added on the pressure fan 12 and increase, noise also descends.Therefore comparing with comparative example 2 is that air-flow with bigger air quantity is carried ion, so diffuser efficiency especially improves.The air quantity of ion diffuser 11a is about 2 times of comparative example 2, this moment 1m place, refrigerator 29a the place ahead level of noise and comparative example 2 the same be 22dB.
The 2nd, utilize this section contraction flow region 13a that rectification is carried out near the disorder of the air the discharge face 14a that flows through ion generating apparatus 14, and can suppress the deflection that flows that pressure fan 12 downstreams produce, promptly so-called bias current is subjected to significantly suppressing so the disorder of air-flow is compared with comparative example 2.Thereby ion is withered away owing to losing electric charge with wall or the collision of other barriers.Again, when ion generating apparatus 14 produces cation and anion with the ratio of equivalent roughly, thereby cation and anion collision ion are withered away.Promptly, if air turbulence, then because of barrier and ion collision with and/or ion between the ion extinction amount that causes of collision many, and if air-flow by rectification, then because of barrier and ion collision with and/or ion between the ion extinction amount that causes of collision reduce, so ion lifetime is elongated.In comparative example 2, ion concentration decays to 1/e in about 3 seconds, and is relative therewith, and the time lengthening that decays to 1/e in the present embodiment was by about 5 seconds.
The 3rd, owing to suppressed to flow through near the disorderly or deflection of the air the discharge face 14a of ion generating apparatus 14, so flow through near the air discharge face 14a of ion generating apparatus 14 homogeneous that becomes.Thereby the ion on the discharge face 14a of ion generating apparatus 14 produces efficient to be improved.That is, can utilize low-voltage or low air quantity to guarantee the ion generation of wishing, also help the reduction noise.
The 4th, by the position relation of air-supply passage 13 with ion generating apparatus 14 is set at, make ion generating apparatus 14 discharge face 14a the width perpendicular to the direction that flows, equate with width towards the air-supply passage 13 of discharge face 14a, suppress dispersing perpendicular to the ion concentration on the direction that flows, ion concentration in the air-supply passage 13 of ion generating apparatus 14 downstream portions becomes roughly even in the plane perpendicular to flow direction, can make ion be stated from air-flow effectively.Therefore, can effectively carry ion and make its diffusion.
The 5th, by aspect ratio optimization, prolong the potential core of jet, and suppressed the decay of wind speed blow-off outlet, so comparing with comparative example 2 significantly, the arrival of air-flow distance prolongs.The arrival of the air-flow that causes about potential core's explanation and because of potential core's prolongation is apart from the principle and the effect that prolong, and is the same with the 1st embodiment.Therefore, if blow-off outlet area and blow-off outlet wind speed are identical, promptly, air quantity is identical, then by making aspect ratio the best of blow-off outlet, can prolong potential core's length, i.e. the arrival distance of air-flow.In other words, identical in potential core's length, i.e. when the arrival of air-flow distance is identical, can reduce air quantity, so can reduce the consumption electric power and the level of noise of pressure fan 12.
＜the 7 embodiment 〉
The following describes the 7th embodiment.Figure 19 is the summary top plan view of the ion diffuser of expression present embodiment, and Figure 20 is the summary sectional side view of the ion diffuser of expression present embodiment.
Present embodiment has been removed the section contraction flow region 13a of the 6th embodiment, and on the air-supply passage 13 of the upstream of the discharge face 14a of ion generating apparatus 14 fairing 17 is set.Thus, can carry out rectification near the disorder of the air the discharge face 14a that flows through ion generating apparatus 14, so can obtain the effect of the section contraction flow region 13a in the 6th embodiment, and eliminate the pressure loss that produces owing to section contraction flow region 13a in the 6th embodiment, can reduce the pressure loss that produces on the air-supply passage 13, so can increase the air quantity of pressure fan 12 and/or the noise of reduction pressure fan 12.Again, removed the wind deflector 16 of the 13b of enlarged tube portion, replaced, air-supply passage 13 has been divided into a plurality of enlarged tube 13b of portion from the tight downstream portion of ion generating apparatus 14.In the present embodiment, air-supply passage 13 is divided into 5 parts on left and right directions, is divided into 3 parts on above-below direction, adds up to be divided into 15 13b of enlarged tube portion, and therefore, disperser blow-off outlet 15 is provided with 15.Again, constitute, the fluid flow passage of being scratched by cut section 3 and each 13b of enlarged tube portion are along with aspect ratio increases near blow-off outlet 5, and the aspect ratio of disperser blow-off outlet 5 each air-supply passage of position is set at about 8.
Other structures are the same with the 6th embodiment, constitute the same with the 6th embodiment, the outer ion blow-off outlet 22 of the refrigerator case that air-supply passage 13 and disperser blow-off outlet 15 and shutter door 21 tops of the front surface setting of refrigerator 20a have is communicated with, and emits outside the refrigerator case, diffusion ion.
The distribution of the ion of present embodiment is different with the 6th embodiment.That is, thereby because the pressure loss of air-supply passage 13 reduces the air quantity increase, ion increases slightly to the arrival distance in refrigerator the place ahead, can make the ion concentration of above-below direction in the refrigerator front space more even, and the ion concentration of refrigerator forward lower part is increased.
In addition, the shape of the outer ion blow-off outlet 22 of disperser blow-off outlet 15 and refrigerator case is not limited to height＜width.
＜the 8 embodiment 〉
The following describes the 8th embodiment.Figure 21 is the stereogram of the ion diffuser of expression present embodiment.
In the present embodiment, the fluid flow passage 3 of the fluid generating device 1d of the air-supply passage 13 of the 7th embodiment and disperser blow-off outlet 15 and the 3rd embodiment and blow-off outlet 5 similarly form.Therefore, the shape of disperser blow-off outlet 15 is height＞width, and air-supply passage 13 is divided into 7 parts on left and right directions, is divided into 2 parts on above-below direction, add up to be divided into 14 13b of enlarged tube portion, and its result, disperser blow-off outlet 15 is provided with 14.Again, constitute, the air-supply passage of being scratched by cut section 3 and each 13b of enlarged tube portion are along with aspect ratio increases near blow-off outlet 5, and the aspect ratio of disperser blow-off outlet 5 locational each air-supply passage (being blow-off outlet height/blow-off outlet width in this case) is set at about 8.
Other structures are the same with the 7th embodiment, with the 7th embodiment similarly, the outer ion blow-off outlet 22 of the refrigerator case that air-supply passage 13 and disperser blow-off outlet 15 and shutter door 21 tops of the front surface setting of refrigerator 20a have is communicated with, and emits outside the refrigerator case, diffusion ion.
The ion distribution of present embodiment is different with the 6th embodiment.Promptly, though reduce a little in the ions diffusion zone of ion left and right directions in the arrival in refrigerator the place ahead distance and refrigerator front space, but the ions diffusion zone of above-below direction significantly enlarges in the refrigerator front space, can make the ion concentration of above-below direction more even, and the ion concentration of the forward lower part of refrigerator is increased.That is, can make ions diffusion in the extensive area of the direction up and down in ion diffuser 11c the place ahead.
＜the 9 embodiment 〉

Illustrate and be used for and the 1st embodiment comparative example relatively.Figure 32 is the summary top plan view of the fluid generating device of expression comparative example 1, and Figure 33 is the summary sectional side view of the fluid generating device of expression comparative example 1.The fluid generating device 100a of comparative example 1 comprises: fluid supply apparatus 2, fluid flow passage 3, produce the blow-off outlet 5 of jet, not shown control part.Fluid by the driving of fluid supply apparatus 2 and be transferred, flows through fluid flow passage 3, becomes jet from blow-off outlet 5 and emits to the outside.Arrow among the figure is represented flowing of fluid.
Again, Figure 34 be expression as the use-case that makes of above-mentioned fluid generating device 100a, the figure of the velocity flow profile when the blow-off outlet of the shape that is height 60mm, width 60mm sends that to blow out flow velocity be the air of 1.5m/s.Grid 1 lattice among the figure are represented 0.5m.In addition, even the fluid of sending from blow-off outlet is that liquid also has much the same tendency.Can find that from Figure 34 the fluid generating device 100a of comparative example 1 exists the arrival of jet apart from short problem.
And find that there is the problem that is unfavorable for to carrying fluid on a large scale in the fluid generating device 100a of comparative example 1.Generally, use the blow-off outlet shape of the fluid generating device of prior art, be mostly low aspect ratio, the jet that blows out from such blow-off outlet is difficult to expand on a large scale, even hypothesis has expanded on a large scale, flow velocity also can significantly reduce.
＜comparative example 2 〉
The following describes and be used for and the 6th embodiment comparative example 2 relatively.Figure 35 is the front view of refrigerator that expression has the ion diffuser of comparative example 2, and Figure 36 is the summary top plan view of the ion diffuser of expression comparative example 2.The ion diffuser 110a that has comparative example 2 at the top of the refrigerator 200 of the comparative example 2 of Figure 35.
The ion diffuser 110a of comparative example 2 comprises: pressure fan 12, air-supply passage 13, the ion generating apparatus 14 that is provided with towards the mode of air-supply passage 13 with discharge face 14a, not shown control part.The ion that utilizes the driving of ion generating apparatus 14 to produce is transferred by the driving of pressure fan 12, flows through air-supply passage 13 and emits to the outside from disperser blow-off outlet 15.In addition, the arrow among Figure 36 is represented the state of air-flow this moment.Again, have ion blow-off outlet 22 outside the refrigerator case that is communicated with aforementioned air-supply passage 13 and disperser blow-off outlet 15, make ion emit, be diffused into outside the refrigerator case on the top of the shutter door 21 of refrigerator 200.In addition, in the suction inlet upstream of the pressure fan 12 of ion diffuser 110a, inner and be provided with not shown air cleaner in order to prevent that oil smoke or dust from invading ion diffuser 110a.
Live outward in the space by as described above cation and anion being released to case around refrigerator 200 the place aheads, can kill the planktonic bacteria that exists in this living space, the living space of health is provided, and planktonic bacteria is invaded outside case in the case in the time of preventing shutter door 21 switchings, realizes the interior environment of case of health.
It is in 15 ℃ the room that Figure 37 is illustrated in room temperature, and ion blow-off outlet 22 becomes H to indoor emitting outside the refrigerator case of the refrigerator 200 of ion diffuser 110a with comparative example 2

mIon, the ion concentration of room each several part when being so-called cluster ion.The size in room is 8 close sizes of couch couch (height 2400mm, width 3600mm, depth 3600mm), and measurement point is that the height apart from ground, room shown in single-point line among Figure 18 is the cross section of 1700mm.Again, the wind speed of the outer ion blow-off outlet 22 of Ci Shi refrigerator case is 1.5mm/s.And this moment, the level of noise at 1m place, refrigerator the place ahead was 22dB.In addition, the control method of Ci Shi ion generating apparatus 14 is the same with the 6th embodiment.
As can be seen from Figure 37, though the ion that has high concentration on every side of the outer ion blow-off outlet 22 of refrigerator case, its zone is narrow, and is not necessarily enough.The ion concentration of the outer 10mm position, ion blow-off outlet 22 the place ahead of the refrigerator case of comparative example 2 is 100,000/cm
3Though, having produced enough ions from ion generating apparatus 14, the ion that becomes high concentration is stuck near the state of blow-off outlet, to the whole diffusion in room.That is, have the refrigerator 200 of the ion diffuser 110a of comparative example 2, have the low problem of diffusivity of ion with respect to the generation of ion.
Enlarge the high zone of ion concentration, get final product, if problem such then that exist the air-supply noise obviously to increase though increase the rotating speed of the pressure fan 12 of ion diffuser 110a.Again, enlarge the high zone of ion concentration, though increasing the ion growing amount of ion generating apparatus 14 gets final product, but exist in this case and not only must significantly improve the voltage that is added on the ion generating apparatus 14, and ion produces sound and increases, and with problems such as the produced simultaneously ozone amount of ion increases explosively.
The product same with the ion diffuser 110a of comparative example 2 and/or ion generating apparatus 14 carries on a lot of household appliances, but all with the above-mentioned the same low problem of diffusivity that has ion.
＜comparative example 3 〉
The following describes and be used for and the 6th embodiment comparative example 3 relatively.Figure 38 is the summary top plan view of the ion diffuser of expression comparative example 3, and Figure 39 is the summary sectional side view of the ion diffuser of expression comparative example 3.
In the ion diffuser 110b of comparative example 3, removed the section contraction flow region 13a of the 6th embodiment.Therefore, the pressure loss of air-supply passage 3 descends, but can not carry out rectification near the disorder of the air the discharge face 14a that flows through ion generating apparatus 14, and can not suppress the deflection that flows that pressure fan 12 downstreams produce, promptly so-called bias current.Promptly, because the disorder of air-flow causes the collision rate between the ion and rises, so ion extinction amount increases, the lifetime of ion, and because the disorderly or deflection of air-flow, make and flow through near the air heterogeneity of discharge face 14a, the ion on the discharge face 14a of ion generating apparatus 14 produces decrease in efficiency.That is, guarantee voltage that the generation of the ion of wishing not only must be higher or bigger air quantity, nor be beneficial to the reduction noise.Flow through the 13b of enlarged tube portion and send because the air-flow band of deflection ion, so the wind speed profile longitudinally at disperser blow-off outlet 15 places also produces deviation from disperser blow-off outlet 15 again.Therefore, the ion concentration of disperser blow-off outlet 15 downstream portions also produces deflection in perpendicular to the plane of flow direction, and the diffusivity of ion descends.
＜comparative example 4 〉
The following describes and be used for and the 6th embodiment comparative example 4 relatively.Figure 40 is the summary top plan view of ion diffuser of expression comparative example 4, and summary sectional side view and the 6th embodiment shown in Figure 15 are just the same.
The ion diffuser 110c of comparative example 4 compares with the ion diffuser 11a of the 6th embodiment, and the shape and the configuration of discharge face 14a and near its air-supply passage 13 are different.If the width perpendicular to the direction that flows of the discharge face 14a of ion generating apparatus 14 is w1, be w2 towards the width of the air-supply passage 13 of discharge face 14a, be set at w2=2 * w1, and, make ion generating apparatus 14 discharge face 14a perpendicular to the central authorities of flow direction with towards the central consistent of the air-supply passage 13 of discharge face 14a and be in same position.Therefore, on perpendicular to the direction that flows, produce the discrete of ion concentration, near the ion concentration height central authorities of disperser blow-off outlet 15, ion concentration is low at two ends.Particularly the deflection of the air of sending from pressure fan 12 is big, when air-flow is mobile along a certain side's in the left and right sides of air-supply passage 13 wall, the wind speed of the disperser blow-off outlet 15 in the downstream of the wall that is carried over is big, and the local wind speed beyond disperser blow-off outlet 15 diminishes.Therefore, the ion concentration of the downstream area of the part that wind speed is little descends, and the big air-flow of wind speed also declines to a great extent so ion produces efficient by the discharge face 14a of ion generating apparatus 14, and the diffusivity of ion reduces.
＜comparative example 5 〉
The following describes and be used for and the 6th embodiment comparative example 5 relatively.Figure 41 is the summary top plan view of ion diffuser of expression comparative example 5, and summary sectional side view and the 6th embodiment shown in Figure 15 are just the same.
The ion diffuser 110d of comparative example 5 has removed the wind deflector 16 of the ion diffuser 11a of the 6th embodiment.Therefore, air-flow is peeled off from the left and right sides wall of the 13b of enlarged tube portion, can not obtain the effect of diffuser, and produces the whirlpool zone in the zone of C shown in Figure 41, the air-supply decrease in efficiency.Again, air-flow is the long range diffusion on the direction to the left and right not, but flows near the central authorities of deflection disperser blow-off outlet 15, thus the ion long range diffusion of direction to the left and right, but only distribute in one direction.And, because the aspect ratio at disperser blow-off outlet 15 places does not have optimization, so the arrival of air-flow distance also shortens.Therefore, the diffusivity of ion descends.
＜comparative example 6 〉
The following describes and be used for and the 6th embodiment comparative example 6 relatively.Figure 42 is the summary top plan view of the ion diffuser of expression comparative example 6, and Figure 43 is the summary sectional side view of the ion diffuser of expression comparative example 6.
The ion diffuser 110e of comparative example 6 is for further having changed the structure that the position is set of ion generating apparatus from comparative example 3.That is, in comparative example 3, with vertically disposing of ion generating apparatus 14 perpendicular to the mode that flows of air-flow, relative with it, in comparative example 6, what make ion generating apparatus 14 is parallel to flowing of air-flow, and is configured on the sidewall on right side of the 13b of enlarged tube portion.Therefore, on the basis of the problem of comparative example 3, also can produce following problems: the concentration height of the ion of sending from the right side downstream, disperser blow-off outlet 15 of the sidewall on the right side of the 13b of enlarged tube portion that is provided with ion generating apparatus 14, and the concentration of the ion of sending from the left side and the central portion of disperser blow-off outlet 15 is low.That is, ion is not the long range diffusion of direction to the left and right, but only is distributed in a direction (to right), so the diffusivity of ion descends.
