Description
Technical field
The present invention relates to the air-flow injecting device and use the drying apparatus for hands of this air-flow injecting device.
Background technique
In air-flow injecting device in the past, make the circulation wind path (for example, with reference to patent documentation 1) of stream branch and link both ends of the surface midway arranging of the ejiction opening that enlarges towards the downstream from suction port from the flowing of high-pressure air of blower device supply for periodic variation.At this, the vibration vibration frequency of high-pressure air can be controlled by the length of change circulation wind path.Particularly, if shorten the length of circulation wind path, it is large that the vibration frequency of then vibrating becomes, if increase the length of circulation wind path, the vibration frequency of then vibrating diminishes.By flowing of periodic variation high-pressure air, can supply with high-pressure air to wide scope.Compare with the situation of a plurality of nozzles of simple configuration, this air-flow injecting device can reduce air quantity keeping under the state of wind speed, thereby reduces power consumption.
Below, the sectional view of reference air-flow injecting device in the past is that Figure 26 describes.As shown in figure 26, by form the ejiction opening 502 of slit-shaped as the diffuser 501 that is expanded into fan-shaped nozzle.Dispose the front ejiction opening 504 of ejection high-pressure air at narrow entrance 503 of diffuser 501.And, in the both ends open section 506,507 that the joint of narrow entrance 503 and front ejiction opening 504 disposes circulation wind path 505, the shunt that possesses cylinder or prism-shaped midway 508 in the expansion section of diffuser 501.
In this air-flow injecting device in the past, the vibration vibration frequency of high-pressure air set hour, circulation wind path 505 is elongated, causes the air-flow injecting device to increase this problem thereby exist.
In addition, when the air-flow injecting device is packed into other whens device, for circulation wind path 505 is accommodated compactly, silicon flexible pipe that can be by softness etc. consists of circulation wind path 505.Yet if apply power from the outside to circulation wind path 505, the distortion such as conquassation easily occur in the wind path 505 that circulates, thereby have the problem of the vibration that can not obtain stable high-pressure air.
In addition, in this air-flow injecting device in the past, when high-pressure air vibrates, owing to producing whirlpool at ejiction opening 502 peripheries, when high-pressure air flows, there is the problem that makes a noise from the whirlpool that produces in the air-flow injecting device.
In addition, in this air-flow injecting device in the past, in order to make the jet stream vibration, shunt 508 is set and promotes the direction of jet stream to change at ejiction opening 502.Even the situation the flow velocity of jet stream also will vibrate slowly narrows down the wind path sectional area by set shunt 508, thereby the pressure loss increases.Therefore, exist the power consumption of blower device to uprise this problem, thereby require to reduce by suppressing the pressure loss rising power consumption of blower device.
In addition, can expect the ejiction opening of this air-flow injecting device use in the past at air regulator, air shower apparatus or drying apparatus for hands etc.When clean air regulator, air shower apparatus, drying apparatus for hands etc., perhaps in the circulation wind path 505 of air-flow injecting device, to accumulate when liquid is arranged because of dewfall, the sectional area that the gas of circulation wind path 505 occupies changes.Consequently, the vibration vibration frequency of gas changes or causes not carrying out vibrating, and can't obtain according to the such problem of removing effect based on gas diffusion effect, water droplet and the dust of gas vibration of design thereby exist.
In addition, in this air-flow injecting device in the past, the high-pressure air from static nozzle is vibrated at emission direction.Yet, supplying with to more wide scope in the situation of high-pressure air from a nozzle, must increase the opening of angle of throw or increase nozzle.In the situation that increases angle of throw, along with away from nozzle center, must increase with the distance of the object of supplying with high-pressure air, thereby wind speed weakens, and therefore has the problem that high-pressure air can't be supplied with to wide scope.
In addition, in the situation that the opening of nozzle increases, if the identical then wind speed of air quantity diminishes, thus must increase air quantity, thereby the problem that exists power consumption to increase.
In addition, about making the movable mode of nozzle, need to be used for making the movable mechanism of nozzle and driving mechanism, so there is the problem that causes the air-flow injecting device to maximize.
In addition, because foreign matter contact from outside and movable nozzle, thereby hinder it normally movable, thus existence can't play stably high-pressure air is supplied with the problem of this effect to wide scope.

Embodiment
Below, with reference to the description of drawings embodiments of the present invention.
(mode of execution 1)
Fig. 1 is the stereogram of the air-flow injecting device of embodiments of the present invention 1, and Fig. 2 is the sectional block diagram of this air-flow injecting device.As shown in Figure 1, air-flow injecting device 11 is made of spray nozzle part 12, circulation wind path 13 and high-pressure air generating means 30.Fig. 2 is the stereogram with the section of the spray nozzle part 12 of the plane A cut-out of Fig. 1.
As shown in Figure 2, spray nozzle part 12 comprises suction port 15, ejiction opening 16, groove 17, primary flow path 18, expansion section 35.At this, suction port 15 is taken into the high-pressure air 14 of supplying with from high-pressure air generating means 30.Ejiction opening 16 is with high-pressure air 14 ejections.Groove 17 is the vibrational stabilization section that is arranged on ejiction opening 16 sides of expansion section 35, and it is the shape that caves in into triangular prism shape.Primary flow path 18 be from suction port 15 to the expansion section 35 stream, the section shape of the direction that it is vertical with the flow direction 31 of high-pressure air 14 is rectangular 32 roughly.At this, the long limit 33 of rectangular 32 is the height of primary flow path 18, and the minor face 34 of rectangular 32 is the width of primary flow path 18.In addition, growing limit 33 is the first surface 20 along the short transverse that consists of primary flow path 18, second 21 limit.
The groove 17 that caves in into triangular prism shape in the bight of bottom with curvature.The central authorities that the position is positioned at top and bottom 36 that arrange as the groove 17 of recess.In addition, groove 17 is arranged to symmetrical with respect to the center line of flow direction 31.In addition, each face in two faces of the tri-prism of formation groove 17 is parallel respectively with expansion section wall 37, and wherein said expansion section wall 37 is walls of the short transverse of expansion section 35.
At this moment, the depth of groove 17 is 0.4 times of length of expansion section 35.At this, utilize the first surface 20 of long limit 33 sides of primary flow path 18, second 21 pressure difference to drive gas in the circulation wind path 13 by the high-pressure air 14 of primary flow path 18.Consequently, pressure difference is put upside down, and gas is driven again, thus, from the high-pressure air 14 of ejiction opening 16 ejection in 19 self-excited vibrations of high-pressure air direction of vibration.
At this, high-pressure air 14 alternately was attached on the first surface 20, second 21 and flows in when vibration.When high-pressure air 14 is attached on a face, for example first surface 20, high-pressure air 14 does not flow at second 21 of opposition side, near the space the mode that air is involved in the high-pressure air 14 that is attached on the first surface 20 enters second 21 from the outside of ejiction opening 16.At this moment, produce whirlpool because high-pressure air 14 and the air that is involved in by high-pressure air 14 occur to interact, thereby become the reason of noise.
According to this structure, by be provided as the groove 17 of vibrational stabilization section at ejiction opening 16, the whirlpool that the high-pressure air 14 because of vibration is produced reduces or disperses.Therefore, can keep the self oscillations of stable high-pressure air 14, and reduce the noise that produces from air-flow injecting device 11.In addition, because can be to wide scope conveying high-pressure air 14, so compare with the situation of a plurality of nozzles of simple configuration, can reduce air quantity keeping under the state of wind speed, thereby can reduce power consumption.
At this, high-pressure air refers to the gas that barometric pressure is above, for example about 3kPa to 12kPa.
In addition, the bight of the bottom by making groove 17 is with curvature, the pressure loss in the time of can reducing high-pressure air 14 by groove 17.
In addition, groove 17 is positioned at the central authorities of top and bottom 36.In addition, groove 17 is arranged to symmetrical with respect to the center line of flow direction 31.Therefore, can make from the high-pressure air 14 of air-flow injecting device 11 ejection according to respect to roughly symmetrical wind speed profile ejection of ejiction opening 16, therefore, can suppress uneven from the wind speed profile of the high-pressure air 14 of air-flow injecting device 11 ejections.
In addition, each face of two faces that consists of the tri-prism of groove 17 is distinguished parallel with the expansion section wall 37 as the wall of the short transverse of expansion section 35.Therefore, when high-pressure air 14 was attached to the expansion section wall 37 that is on the high-pressure air direction of vibration 19, a face of tri-prism that consists of groove 17 was parallel with the emission direction of high-pressure air 14.Consequently, can not upset flowing of high-pressure air 14, reduce so can reduce the wind speed of high-pressure air 14.
In addition, the depth of groove 17 is more than 0.01 times below 0.6 times of length of expansion section 35.Therefore, the change of the whirlpool that can establishment produces because of the high-pressure air 14 of vibration by groove 17 is large, can reduce the noise that produces from air-flow injecting device 11.At this, in 0.01 times the situation of depth less than the length of expansion section 35 of groove 17, can not observe significantly and suppress the large effect of whirlpool change, if greater than 0.6 times, then the vibration of high-pressure air 14 becomes unstable, and is therefore not preferred.
(mode of execution 2)
Fig. 3 is the sectional block diagram of structure of the air-flow injecting device of expression embodiments of the present invention 2, and Fig. 4 is the stereogram of the outward appearance of this air-flow injecting device of expression, and Fig. 5 is the plan view of shape of the ejiction opening of this air-flow injecting device of expression.In embodiments of the present invention 2, omit the explanation of the constitutive requirements identical with mode of execution 1, difference mainly is described.
As shown in Figure 3, air-flow injecting device 101 possesses: ejiction opening 102, suction port 103, primary flow path 104, expansion section 123.At this, flow into from suction port 103 from the high-pressure air of supplying with as for example high-speed turbine blower of high-pressure air generating means, and spray to the outside from ejiction opening 102 by primary flow path 104.Expansion section 130 and suction port 103 are communicated with by primary flow path 104.The section shape of ejiction opening 102 and suction port 103 is respectively oblong-shaped.Expansion section 123 is bi-side from primary flow path 104 towards zone that ejiction opening 102 enlarges with about 30 ° angle.
Thus, it is larger than suction port 103 that the opening area of ejiction opening 102 becomes, and the high-pressure air that flows into suction port 103 can spray with wide-angle from ejiction opening 102.And, possessing two control mouths 105 that go out from primary flow path 104 vertical branches in the bi-side of primary flow path 104, each control mouthfuls 105 is communicated with cavity 106.As shown in Figure 4, the joint 107 of pipe arrangement connection usefulness is set in the part of cavity 106, each joint 107 of the left and right sides connects by pipe 108, thereby forms circulation wind path 109.
In addition, 123 top and bottom 124 are provided with the jut 110 as vibrational stabilization section as follows in the expansion section, jut 110 prolongs at the mediad emission direction of the primary flow path 104 that arrives expansion section 123, and section is symmetrical with respect to the face vertical with orientation of oscillation.That is, jut 110 is arranged on the central authorities of the top and bottom 124 that consist of expansion section 123.In addition, jut 110 is with respect to center line 125 symmetries of the width of the primary flow path 104 that arrives expansion section 123.
At this moment, jut 110 is arranged to join with ejiction opening 102, and the sectional area of ejiction opening 102 is not narrowed down.
According to said structure, at the high-pressure air that produces from the high-pressure air generating means from suction port 103 during by primary flow path 104 and from ejiction opening 102 ejection, its become under the effect of attached wall effect (coanda effect) be attached to expansion section 123 about the air-flow on the side arbitrarily.
Next, if in case produce air-flow on the side be attached to primary flow path 104, then the flow velocity of the high-pressure air of the intersection of side is fast, therefore, and the control mouth 105 that arranges in the accompanying side's of high-pressure air side and the pressure step-down in the cavity 106.Relative therewith, so the side's that high-pressure air does not adhere to side uprises because of the slow pressure of the flow velocity of high-pressure air.Each control mouth 105 and cavity 106 are communicated with by circulation wind path 109, so pressure is delivered to the control mouth 105 of opposition side by circulation wind path 109.Then, the pressure rise in the side's that high-pressure air is accompanying control mouth 105 and the cavity 106, the pressure drop in the side's that high-pressure air does not adhere to control mouth 105 and the cavity 106.Thus, the mobile pressure decreased that makes in the control mouthfuls 105 that is attached to high-pressure air on a side the side, thus under the effect of attraction force, switch to side attachment to opposition side.By alternately carrying out this motion, thereby jet stream becomes the motion of vibration.
At this, the bi-side of expansion section 123 are so that approximately 30 ° angle is extended.Therefore, the direction of jet stream enlarges and vibrates with about 30 ° angle, when this angle of excessive increase, is difficult to utilize attached wall effect to make high-pressure air to side attachment, so be preferably below 30 °.
In addition, when the flow velocity of the high-pressure air of internal flow was slack-off, the motion of this jet stream vibration was no longer vibrated.Therefore, in order also to carry out oscillatory movement under the flow velocity slowly, the shunt of the column that is connected with the top and bottom of expansion section 123 is set in the prior art, still, because the sectional area of expansion section 123 is dwindled, the pressure loss rises.Therefore, in embodiments of the present invention 2, for the sectional area of ejiction opening 102 being dwindled, preferably in the mode of joining with ejiction opening 102 jut 110 is set with doing one's utmost.Consequently, make the flow direction left and right sides either direction deflection of the high-pressure air that flows in primary flow path 104 by the jut 110 that is arranged on expansion section 123, distance with the side of primary flow path 104 furthers.Therefore, attached wall effect is improved, and high-pressure air easily is attached on the side of primary flow path 104.Even flow velocity is slow, also can makes jet stream vibration and suppress the pressure loss and rise, thereby can reduce the power consumption of high-pressure air generating means and realize energy-saving.
In addition, the shape of jut 110 is with respect to center line 125 symmetries of the width of the primary flow path 104 that arrives expansion section 123.Therefore, all be identical owing to being attached to mobile its flowing resistance in any one side at primary flow path 104 mobile high-pressure airs, so which side jet stream is attached on all can vibrate with identical flow velocity.
And the shape of jut 110 is protruded towards inside from ejiction opening 102, and the section of the direction vertical with respect to the flow direction of primary flow path 104 is triangle.Thus, after high-pressure air that primary flow path 104 flows and jut 110 collisions, to left and right sides separation bubble, therefore in the attached wall effect of raising, can also suppress the reducing of sectional area of ejiction opening 102.Therefore, can further suppress the rising of the pressure loss, reduce the power consumption of high-pressure air generating means, thereby can realize energy-saving.
In addition, the sectional area on the direction that the flow direction with respect to primary flow path 104 of jut 110 is vertical is larger than the inflow side in the ejection side.Thus, become the sectional area of primary flow path 104 with respect to the structure of the slow variation of flow direction, can not produce the pressure loss because rapid sectional area changes, rise thereby can suppress the pressure loss.
Generally speaking, the area of the air that flows and the interface of stream wall is larger, and attached wall effect is higher.Therefore, take the orientation of oscillation of jet stream as laterally, take the direction vertical with orientation of oscillation for vertical, the opening of suction port 103 is arranged to the horizontal length of the longitudinally Length Ratio of suction port 103 long, thereby makes the side of the primary flow path 104 that is provided with control mouthfuls 105 become large.Thus, under the effect of attached wall effect, easily effectively be attached to the side at the high-pressure air of the internal flow of primary flow path 104.In addition, as shown in Figure 5, according to experiment as can be known, preferably making longitudinally, length is horizontal more than 1.2 times of length.
At this, the oscillation frequency that the speed of jet stream vibration is used as the number of times in per 1 second represents, Fig. 6 represents the oscillatory regime of jet stream of the air-flow injecting device of embodiments of the present invention 2, the relation of flow velocity shown in Figure 6 and oscillation frequency.In Fig. 6, the situation that jut 110 is not set is by single-point line expression, and the situation that only at the single face of ejiction opening 102 jut 110 is set is illustrated by the broken lines, and represented by solid line in the two-sided situation that jut 110 is set of ejiction opening 102.
In the situation that jut 110 is arranged on ejiction opening 102, compare with the situation that does not have jut 110, can obtain following effect, namely, be provided with the structure of jut 110 in the situation that identical its oscillation frequency of flow velocity is higher, even and flow velocity is slower also can vibrate.And, compare with the situation that jut 110 is arranged on the single face, if jut 110 be arranged on two-sided on, then more easily vibration, even the flow velocity of jet stream also can make its vibration slowly, and suppress the pressure loss and rise, can reduce the power consumption of high-pressure air generating means thus and realize energy-saving.
As an example, be that the length of 4mm * 13mm, circulation wind path 109 is that 700mm, jut 110 form in the situation of vertical 5mm, horizontal 5mm, height 5mm in the sectional area of primary flow path 104, oscillation frequency under the flow velocity of 100m/sec in the situation that not have jut 110 be 25Hz for 20Hz, in the situation of jut 110 (single face), in the situation that jut 110 (two-sided) is 33Hz, higher in the effect of the two-sided structure that is provided with jut 110.
In addition, as the method for change oscillation frequency, if increase the length of circulation wind path 109, oscillation frequency step-down then, if shorten the length of circulation wind path 109, then oscillation frequency uprises.In embodiments of the present invention 2, circulation wind path 109 108 is made of pipe, and be configured to joint 107 dismounting freely, thus, can change according to purposes the length of pipe 108, can change the oscillation frequency of jet stream.
(mode of execution 3)
Fig. 7 is the sectional block diagram of structure of the air-flow injecting device of expression embodiments of the present invention 3.Give identical symbol for the constitutive requirements identical with embodiment of the present invention 2, and omit detailed description thereof.
The first control mouthfuls 111 that goes out with primary flow path 104 vertical branches being provided with of primary flow path 104 midway is being provided with and the second control of primary flow path 104 branches mouthfuls 112 of the expansion section 123 that enlarges towards the downstream with about 30 ° angle midway.Circulation wind path 109 possesses two systems altogether so that the first control mouthful the 111 and second control mouthful 112 modes that are communicated with are respectively arranged a system about primary flow path 104.
The central authorities of 123 top and bottom possess the jut 110 that protrudes towards the inboard in the expansion section.
According to said structure, the part of air that is attached to the side of primary flow path 104 flows into the second control mouthfuls 112.When the pressure in the second control mouth 112 uprises, air is in the 109 interior transmission of circulation wind path, thereby the pressure in the first control mouthfuls 111 uprise, so that the high-pressure air that is attached on the side of primary flow path 104 extruded to opposition side, thereby switch to side attachment to opposition side.Make the jet stream vibration by repeating this phenomenon.
This situation is also same with embodiments of the present invention 2, the high-pressure air and 123 juts that possess, 110 collisions in the expansion section that flow in primary flow path 104.Then, either direction deflection to the left and right, thereby under the effect of attached wall effect, be attached near distance a side the side and flow, thereby jet stream is vibrated.
In addition, by suction port 103, primary flow path 104, expansion section 123, ejiction opening 102 and circulation wind path 109 are set at grade, primary flow path 104 and circulation wind path 109 are arranged to along not crooked up and down.Therefore, compare with mode of execution 2, can suppress the pressure loss of high-pressure air when internal flow and rise, reduce the power consumption of high-pressure air generating means, thereby can realize energy-saving.
(mode of execution 4)
In embodiments of the present invention 4, give identical symbol to the constitutive requirements identical with mode of execution 3, omit detailed description thereof.
Fig. 8 is the stereogram of structure of the drying apparatus for hands of expression embodiments of the present invention 4, and Fig. 9 is the side view cutaway drawing of this drying apparatus for hands of expression.
Such as Fig. 8 and shown in Figure 9, the main body 113 that is fixed on the wall possesses: the hand drying room 114 with the space that can insert hand; To the 114 interior ejections of hand the drying room approximately embodiments of the present invention 2 of the high speed jet stream of 70～120m/s or 3 spray nozzle part 115.In addition, main body 113 possesses: to the air flow path 116 of spray nozzle part 115 conveying high-pressure air; To the high-pressure air generating means 117 of air flow path 116 pressure conveying high-pressure air, be taken into the suction port 118 of extraneous gas.In addition, in main body 113, control device 119 as the running of controlling high-pressure air generating means 117 for example possesses the circuit substrate that is equipped with microcomputer, possesses for example infrared sensor as the detection unit 120 of high-pressure air generating means 117 being switched on for detection of inserting the hand in the drying room 114 in one's hands.
In said structure, when the hand with adhesional wetting inserts hand drying room 114, detect the existence of hand by detection unit 120, to control device 119 transmitted signals, make 117 actions of high-pressure air generating means by control device 119.Thus, suck outside air from the suction port 118 that is arranged on hand drying room 114, and the high-pressure air after will boosting by high-pressure air generating means 117 sprays from spray nozzle part 115 via air flow path 116.At this moment, the jet stream that sprays from spray nozzle part 115 vibrates, and thus, wind and the hand integral body of stretching out is collided equably, can make hand dry rapidly.
At this, in embodiments of the present invention 4, the angle that the opening of the expansion section 123 of spray nozzle part 115 is expanded towards the downstream is 30 °, at five ejiction openings 102 of orientation of oscillation configuration of jet stream, makes thus that the hand that inserts in the drying room 114 in one's hands is whole to be bumped with wind facies.The configuration quantity that expands angle and ejiction opening 102 of this jet stream is preferably suitably set according to the actual use of drying apparatus for hands.
In drying apparatus for hands in the past, collide equably in order to make wind and hand integral body, need to use the nozzle of the slit-shaped that does not have gap, air quantity must increase, so the power consumption of high-pressure air generating means 117 also increases.Yet, in the drying apparatus for hands of embodiments of the present invention 4, owing to jet stream vibrates, so even the quantity of spray nozzle part 115 is few, wind and hand integral body are collided and can reduce air quantity, thereby can reduce the power consumption of high-pressure air generating means 117 and realize energy-saving.In addition, because flow velocity is very fast for about 70～120m/sec, so compare the more remarkable effect that it reduces the pressure loss with the shunt of the column of aforesaid prior art.

Figure 10 is the stereogram of the air-flow injecting device of embodiments of the present invention 5, and Figure 11 is the sectional block diagram of the spray nozzle part of this air-flow injecting device, and Figure 12 is the exploded view of the circulation wind path section of this air-flow injecting device.Need to prove, Figure 11 is the figure that cuts off the air-flow injecting device of Figure 10 with plane B.In embodiments of the present invention 5, omit the explanation of the constitutive requirements identical with mode of execution 1～4, difference mainly is described.
As shown in figure 10, air-flow injecting device 211 possess by joint 226 be arranged to can dismounting spray nozzle part 212 and circulation wind path section 213.Such as Figure 11 and shown in Figure 12, spray nozzle part 212 comprises: be taken into the suction port 215, OBL ejiction opening 216 of high-pressure air 214, be communicated with primary flow path 217 and the expansion section 240 of expansion sections 240 from suction port 215.Primary flow path 217 is rectangulars take the width of primary flow path 217 as minor face, take the height of primary flow path 217 as long limit with respect to the section shape of the Vertical direction of the flow direction 241 of high-pressure air 214.Expansion section 240 is zones that 216 stream enlarges from primary flow path 217 to ejiction opening.
Circulation wind path section 213 is housed in the inside of casing 218.Circulation wind path section 213 possesses circulation wind path 221, this circulation wind path 221 is first surface 219 branches of the long side of rectangular primary flow path 217 from section shape, and be communicated with second 220 of the long side of the primary flow path 217 of opposition side, and its internal surface has water proofing property.Like this, in the air-flow injecting device 211 of embodiments of the present invention 5, circulation wind path 221 is housed in the casing 218.
In addition, circulation wind path section 213 possesses: silicon chip 222, its sealing mechanism for being used for preventing that air from leaking from circulation wind path 221; O RunddichtringO 223, it is used for preventing occurring air leakage when joint 226 links with spray nozzle part 212.Each casing 218 in the hole 224 by screw threads for fastening and integrated.
At this, the high-pressure air 214 of for example 10kPa by primary flow path 217 utilizes first surface 219 at the long side of primary flow path 217, second 220 pressure difference to drive gas in the circulation wind path 221.Consequently, pressure difference is put upside down, and gas is driven again, thus, and from high-pressure air 214 self-excited vibration on high-pressure air direction of vibration 225 of ejiction opening 216 ejections.
At this moment, the sectional area of circulation wind path 221 is arranged to more than 0.25 times of sectional area of primary flow path 217.In the situation that sectional area is less than 0.25 times, high-pressure air 214 vibrates astatically, and is therefore not preferred.As the upper limit of the sectional area of circulation wind path 221, so long as in the design of air-flow injecting device 211, allow just do not have what problem in the scope of size.
According to this structure, by at the size that is defined as expectation 64cm for example
3About the inside of casing 218 of size take in circulation wind path 221, thereby can suppress the maximization of air-flow injecting device 211.
In addition, because circulation wind path 221 is formed on the inside of casing 218, so even apply power from the outside, the shape of circulation wind path 221 can not change yet.Therefore, high-pressure air 214 is stably vibrated, can be to wide scope conveying high-pressure air 214.Consequently, compare with the situation of a plurality of nozzles of simple configuration, can reduce air quantity in the situation that keep wind speed, thereby can reduce power consumption.
In addition, circulation wind path 221 is turned back in the inside of casing 218 repeatedly three-dimensionally.By the quantity that increase is turned back, can in the casing 218 of arbitrary shape, accommodate circulation wind path 221, thereby can improve the design freedom of air-flow injecting device 211.
In addition, spray nozzle part 212 can be in joint 226 dismounting with circulation wind path section 213.That is, circulation wind path 221 can be from primary flow path 217 dismounting.Therefore, produce undesirable conditions in the situation that foreign matter enters circulation wind path 221 interior grades at air-flow injecting device 211, can easily place under repair by changing casing 218, thereby can improve the maintainability of air-flow injecting device 211.Example as connecting means shows following method, and is namely that the cylindrical duct that is arranged in spray nozzle part 212 and the circulation wind path section 213 is inserted into each other, is fixed by the O RunddichtringO 223 that is arranged on circulation wind path section 213.Yet, so long as do not produce the method for air leakage at joint 226, also can use other method.
In addition, because casing 218 can decompose, so produce undesirable conditions in the situation that foreign matter enters circulation wind path 221 interior grades at air-flow injecting device 211, the repairing such as casing 218 interior partial solutions can be cleaned, thereby can improve the maintainability of air-flow injecting device 211.
In addition, leak from circulation wind path 221 owing to can prevent air, so high-pressure air 214 is stably vibrated.
In addition, the sectional area of circulation wind path 221 is set as more than 0.25 times of sectional area of primary flow path 217, produces thus high-pressure air 214 is changed at the enough pressure of circulation wind path 221 internal vibrations, and high-pressure air 214 is stably vibrated.At this, if the sectional area of circulation wind path 221 increases, then can cause the maximization of air-flow injecting device 211 with involving, so, be limited to the scope that aspect the designed size of air-flow injecting device 211, allows on the sectional area of circulation wind path 221.
In addition, because the internal surface of circulation wind path 221 has water proofing property, so, even in the contaminated situation in the inside of circulation wind path 221, also can easily rub off the dirt, thereby can improve the maintainability of air-flow injecting device 211.At this, water proofing property refers to, the wrapping angle of water is the surface state below 180 ° more than 90 °.As the creating method of the surface state of water proofing property, be that polymeric compound or silicone are the known method of polymeric compound etc. as long as use the coating fluororesin.
