And, in the present note, by axleTo as fore-and-aft direction, the quiet wing cell side with respect to aerofoil fan is illustrated to each portion as front sideThe shape and the position relationship that divide. But, not intend to limit and send by the definition of this fore-and-aft directionBlower fan and quiet wing unit setting party in use to.
Fig. 1 is the side view with the fan 1 of quiet wing unit 50. This fan 1 is to pass through motor10 power rotates impeller 40, thus the pressure fan of blowing to axial front. Fan 1 is for example putPut on the floor of family, enjoy the cool for user. As shown in Figure 1, this fan 1 has motor10, motor cover 20, foot 30, impeller 40, quiet wing unit 50 and cover 60. In addition, at figureIn 1, in order to express impeller 40 and quiet wing unit 50, with the STA representation cover 60 having dissectd. SeparatelyOutward, fan 1 also can be arranged on wall or ceiling.
Motor 10 is the power sources that impeller 40 are provided for to the power of rotation. Motor 10 is receivedIn the inside of the motor cover 20 as housing. Motor 10 has along rotation 9 to axial frontThe axle 11 extending. The leading section of axle 11 is more outstanding to axial front than the front surface of motor cover 20. IfProvide drive current to motor 10, by being configured between coil in motor 10 and magnetMagnetic force produces the torque centered by rotation 9. Thus, the axle 11 of motor 10 is with rotating shaftRotation centered by line 9. Solid arrow R0 in Fig. 1 represents the direction of rotation of axle 11.
For example Brushless DC motor is used for to motor 10. Brushless DC motor is owing to not existing because of brushWearing and tearing and the performance degradation that produces is therefore long than the brush motor life-span.

RespectivelyThe ora terminalis of the direction of rotation front side of rotating vane 42 is positioned at than the ora terminalis of direction of rotation rear side by axleRearward position.
If motor 10 is driven, the axle 11 of motor 10 and the impeller 40 that is fixed on axle 11 withCentered by rotation 9 to the direction rotation identical with the direction of rotation R0 of axle 11. So,Gas is accelerated by multiple rotating vanes 42, and around impeller 40, generation is from axial rearward direction to axiallyThe air-flow in front. ,, in this fan 1, formed and produced to axle by motor 10 and impeller 40The aerofoil fan 70 of air-flow forwards.
Impeller 40 is for example the single resin component being obtained by injection mo(u)lding. But, impeller40 also can be made up of multiple parts. For example, cup portion 41 with multiple rotating vanes 42 can be alsoThe parts of split mutually. And impeller 40 can be also the portion being made up of the material except resinPart.
Quiet wing unit 50 is the mechanisms for adjusting the air-flow producing from impeller 40. In other words, quietThe air-flow producing from aerofoil fan 70 is adjusted in wing unit 50. Quiet wing unit 50 is positioned at impeller 40Axially front, and roughly configure coaxially with the rotation 9 of impeller 40. In other words, quiet wing listThe axial front that unit 50 is positioned at aerofoil fan 70, and with the rotation 9 of aerofoil fan 70 roughlyConfiguration coaxially. Quiet wing unit 50 is what to separate with axle 11 and impeller 40. Therefore, at axle 11And impeller 40 is while rotating, quiet wing unit 50 does not rotate and is static. As shown in Figure 1, quiet wing listUnit 50 has: multiple straightener(stator) blades 51; And the switching mechanism of the position of switching straightener(stator) blade 5152。
The user of fan 1 is switched the position of multiple straightener(stator) blades 51 by operation shifting mechanism 52,Can adjust the degree of gathering or the diffusion of the air-flow producing from impeller 40. Below, will with do not have quietThe situation of wing unit 50 is compared the state that the air-flow producing from impeller 40 is assembled and is called " dot pattern ".In other words, dot pattern refers to and make the gas that produces from aerofoil fan 70 compared with there is no quiet wing unit 50The pattern of stream aggregation. In dot pattern, fan 1 can be to being positioned at the making of axial front of fan 1User intensively send stronger wind. And, below, by compared with there is no the situation of quiet wing unit 50The state of the Diffusion of gas stream producing from impeller 40 is called " wide area pattern ". In other words, wide area mouldFormula refers to and make the Diffusion of gas stream that produces from aerofoil fan 70 compared with there is no the situation of quiet wing unit 50Pattern. In wide area pattern, fan 1 can be to being positioned at multiple users of larger scopeSend more slow wind. In other words, switching mechanism 52 switches rectification leaf between dot pattern and wide area patternThe position of sheet 51.
Cover 60 is the frameworks that impeller 40 and quiet wing unit 50 are contained in to inner cage shape. Cover 60Allow that the air-flow being produced by impeller 40 passes through, and prevent that user from touching the impeller 40 of rotation. AsShown in Fig. 1, cover 60 has peripheral ring 61, multiple fronts spoke 62 and multiple rears spoke 63.Peripheral ring 61, multiple fronts spoke 62 and multiple rears spoke 63 are formed by metals such as iron respectively.But the surface of these parts also can be covered by resin film.
Peripheral ring 61 is the radial outside of circular encirclement impeller 40. Multiple fronts spoke 62 is quietThe front of wing unit 50 is radial extension. The end of the radial outside of each front spoke 62 is fixedIn peripheral ring 61. And quiet wing unit is fixed in the end of the radially inner side of each front spoke 6250 switching mechanism 52. Multiple rears spoke 63 is radial extension in the axial rearward direction of impeller 40.Peripheral ring 61 is fixed in the end of the radial outside of each rear spoke 63. And, each rear spokeMotor cover 20 is fixed in the end of 63 radially inner side.
Then the more detailed structure of quiet wing unit 50 is described.
Fig. 2 and Fig. 5 are the stereograms of quiet wing unit 50. Fig. 3 and Fig. 6 are quiet wing unit 50Side view. Fig. 4 and Fig. 7 are the front views of quiet wing unit 50. The gas producing from impeller 40Flow as the dotted arrow F 1 in Fig. 2 and Fig. 5 as a whole towards axial front. But,This air-flow have as dotted arrow F 2 in Fig. 2 and Fig. 5 to the direction of rotation of impeller 40The rotational component of the direction rotation that R0 is identical.
As mentioned above, quiet wing unit 50 has: multiple straightener(stator) blades 51; And switching straightener(stator) bladeThe switching mechanism 52 of 51 position.
Multiple straightener(stator) blades 51 upwards roughly equally spaced configure in week around switching mechanism 52.Each straightener(stator) blade 51 extends and forms to radial outside near of rotation 9. Each straightener(stator) blade51 shape both can linearlyly also can be circular-arc. Fig. 2, Fig. 3, Fig. 4, Fig. 5,In the example of Fig. 6 and Fig. 7, each straightener(stator) blade 51 is to the linearly extension of radial outside.
In addition, in the case of the front spoke 62 of cover 60 tilts, also can make each straightener(stator) bladeThe ora terminalis of 51 front spoke 62 sides is along the inclination of front spoke 62 and tilt. For example, forwardlySpoke 62 is with along with to radial outside and in situation about tilting to the mode of axial rearward direction side displacement, eachThe ora terminalis of front spoke 62 sides of straightener(stator) blade 51 also can be with along with to radial outside and to axiallyThe mode of rear side displacement tilts. Thus, can effectively utilize the space of the inside of cover 60Configure quiet wing unit 50. Therefore, fan 1 can axially realized save space.
The outer end that switching mechanism 52 switches straightener(stator) blade 51 is simultaneously circumferential with respect to inner endRelative position (hereinafter referred to as phase angle) and straightener(stator) blade 51 with respect to orthogonal with rotation 9The inclination (hereinafter referred to as pitch angle) of plane. Thus, multistage between dot pattern and wide area patternGround switches the position of straightener(stator) blade 51.
Fig. 2, Fig. 3 and Fig. 4 illustrate the quiet wing unit 50 under dot pattern. As Fig. 2, Fig. 3 andShown in Fig. 4, in dot pattern, the angle of multiple straightener(stator) blades 51 is the shape approaching with axially parallelState. Therefore,, in dot pattern, the component that directly enters of the air-flow producing from impeller 40 is not rectified blade51 diffusions, and as dotted arrow F in Fig. 23, be sent to axial front. And, as shown in Figure 4,The outer end of straightener(stator) blade 51 is positioned at impeller 40 with respect to the circumferential relative position of inner endThe direction that direction of rotation R0 is contrary. Therefore, if the rotational component of the air-flow producing from impeller 40 withStraightener(stator) blade 51 bumps against, and as dotted arrow F in Fig. 44, changes this to radially inner side and flowsDirection, and be gathered near rotation 9.
Therefore,, in dot pattern, directly enter near revolving of the component air-flow with being gathered in rotation 9Turn component stack, can intensively send stronger wind to the user in the axial front that is positioned at fan 1.And, can be by the extremely axially farther place in front of the airflow feeding producing from impeller 40.
Fig. 5, Fig. 6 and Fig. 7 illustrate the quiet wing unit 50 under wide area pattern. As Fig. 5, Fig. 6 withAnd shown in Fig. 7, in wide area pattern, the angle of multiple straightener(stator) blades 51 is close to hanging down with axialStraight state. Therefore, in wide area pattern, the air-flow producing from impeller 40 directly enter component by wholeStream blade 51 spreads, and as dotted arrow F in Fig. 55, is sent to radial outside. And, asShown in Fig. 7, the outer end of straightener(stator) blade 51 with respect to the circumferential relative position of inner end be positioned atThe identical direction of direction of rotation R0 of impeller 40. The rotation of the air-flow therefore, producing from impeller 40If component bumps against with straightener(stator) blade 51, as the dotted arrow F 6 in Fig. 7 to radial outsideChange flow direction, and diffusion.
Therefore, in wide area pattern, the air-flow producing from impeller 40 directly enter component and rotation pointAmount is all diffused, can be to being positioned at multiple users in a big way in axial front of fan 1Send more slow wind.
So, in this fan 1, directly the entering component and revolve of the air-flow producing from aerofoil fan 70Turn component by bumping against with each straightener(stator) blade 51 of quiet wing unit 50, change direction. Therefore,By switching phase angle and the pitch angle of this straightener(stator) blade 51, can change the diffusion of air-flow or gatherThe degree of collection.
Multiple straightener(stator) blades 51 have breach 51B at radial inner end respectively. In more detail, manyIndividual straightener(stator) blade 51 has forniciform breach 51B at radial inner end. Thus, multiple rectification leavesNear the air-flow inner end of sheet 51 easily leads to axial front. Therefore, can make rotation 9Near air quantity increases. As shown in Figure 2, preferably breach 51B straightener(stator) blade 51 radially inEnd and be positioned at the axial front side of straightener(stator) blade 51 in dot pattern. Thus, even at dot patternIn, also can make straightener(stator) blade 51 and impeller 40 maintain a certain distance, thereby make from impeller 40The air-flow producing bumps against with straightener(stator) blade 51 equably.
And multiple straightener(stator) blades 51 have multiple projection 51A at the mask of aerofoil fan 70 sides respectively.Specifically, as shown in Fig. 2, Fig. 3, Fig. 5 and Fig. 6, multiple straightener(stator) blades 51 exist respectivelyThe mask of impeller 40 sides has multiple projection 51A. Multiple projection 51A can produce from impeller 40In a part for air-flow, form trickle turbulent flow, suppress to produce because air-flow departs from straightener(stator) blade 51The peeling off of a large amount of air-flows. Thus, can suppress the wind noise that produces due to peeling off of air-flow,Noise while reducing air-supply. In the example of Fig. 2, Fig. 3, Fig. 5 and Fig. 6, attached in outer endNear the ora terminalis of the axial front side along each straightener(stator) blade 51 of near and inner end arranges projection 51A. ButAlso can identical projection 51A be set in other positions of straightener(stator) blade 51.
Then the more detailed structure of switching mechanism 52 is described.
Switching mechanism 52 switches the position of multiple straightener(stator) blades 51. It is many that switching mechanism 52 has connectionThe single functional unit of individual straightener(stator) blade 51. By functional unit is operated, straightener(stator) blade51 outer end with respect to the circumferential relative position of inner end and straightener(stator) blade 51 with respect to revolveThe pitch angle of the orthogonal plane of shaft axis 9 is switched simultaneously. Switching mechanism 52 is the multiple rectifications of supportingBlade 51, and multistage the phase angle of each straightener(stator) blade 51 and the mechanism of pitch angle of switching. In other words,Switching mechanism 52 is that two-stage is switched the outer end of straightener(stator) blade 51 with respect to the week of inner end with ShangdiTo relative position and straightener(stator) blade 51 with respect to the pitch angle of the orthogonal plane of rotation 9Mechanism. Fig. 8 and Fig. 9 are the figure that the structure of switching mechanism 52 is schematically shown. In addition, existIn each figure after Fig. 8, in order to express switching mechanism 52, only indicate a straightener(stator) blade 51,But be in fact connected with one or more straightener(stator) blade 51 at single switching mechanism 52.
As shown in FIG. 8 and 9, switching mechanism 52 has fixed base 521 and can rotating ring 522.In more detail, switching mechanism 52 have fixed base 521, can rotating ring 522 and be connected in wholeThe connecting portion 540 of stream blade 51. Can centered by rotation 9, connect rotatably by rotating ring 522Be connected to fixed base 521. And the either party in fixed base 521 and connecting portion 540 hasThe first anti-delinking part 531. The opposing party in fixed base 521 and connecting portion 540 has first anti-De-portion remains first stopper section 541 that can rotate. Can rotating ring 522 and connecting portion 540 inEither party has and is configured in the axial front of the first anti-delinking part 531 or the second anti-delinking part of axial rearward direction532. Can rotating ring 522 and connecting portion 540 in the opposing party have the second anti-delinking part 532 keptFor second stopper section 542 that can rotate. In the present embodiment, fixed base 521 and can rotating ring522 have respectively anti-delinking part. The anti-delinking part below fixed base 521 being had is called the first anti-delinking part531, the anti-delinking part can rotating ring 522 having is called the second anti-delinking part 532.
There is connecting portion 540 at straightener(stator) blade 51. Connecting portion 540 has respectively and the first anti-delinking part531 and the stopper section of the second anti-delinking part 532 correspondences. In the example of Fig. 8 and Fig. 9, connecting portion540 a pair of stopper section is arranged in the different direction of direction of extending from the inner end of straightener(stator) blade 51.Connecting portion 540 can be both and the parts of straightener(stator) blade 51 one resin formings, and can be alsoBe installed on the parts of straightener(stator) blade 51 as point body component. Below, will be right with the first anti-delinking part 531The stopper section of answering is called the first stopper section 541, and the stopper section corresponding with the second anti-delinking part 532 is calledThe second stopper section 542.
The mode that the second stopper section 542 can slide axially with the second anti-delinking part 532 is formed as edgeAxially extended tubular space. And in the first stopper section 541, the first anti-delinking part 531 along axleTo slip be limited. So, in this example, the shape of the first stopper section 541 and second onlyThe shape of stopper 542 is different.
Figure 10 is the cutaway view that is inserted with the connecting portion 540 under the state of anti-delinking part in stopper section. AsShown in Figure 10, anti-delinking part has: spherical anticreep top ends 53A; And from anticreep top ends 53AThe anticreep axial region 53B extending to rotation 9 sides. In other words, the outer surface of the first anti-delinking part 531Or the inner surface of described the first stopper section 541 is spherical, the outer surface of the second anti-delinking part 532 orThe inner surface of two stopper sections 542 is spherical. Anticreep top ends 53A rotating in stopper sectionState be kept. And, inside in the footpath of the first stopper section 541 and the second stopper section 542Side is provided with opening 543. Anticreep axial region 53B in the scope of opening 543 can with anticreep topThe 53A of portion together rotates.
In addition, in the example of Figure 10, the shape of anticreep top ends 53A is spherical, but as long as anti-De-top ends 53A is the state that can rotate in stopper section, also can be other shapes. For example,It is hemispherical or polyhedron-shaped that anticreep top ends 53A also can be. But, preferably anticreep top endsEither party in the outer surface of 53A or the inner surface of stopper section is dome shape.
By rotating by rotating ring 522, the outer end of straightener(stator) blade 51 is circumferential with respect to inner endRelative position and straightener(stator) blade 51 with respect to the pitch angle of the orthogonal plane of rotation 9 by withIn time, switches. More particularly, if user catch as functional unit can rotating ring 522 and make canRotating ring 522 is rotating in a circumferential direction, and in the inside of the first stopper section 541, revolve the first anti-delinking part 531Turn, the inner end of straightener(stator) blade 51 is with the tie point of the first anti-delinking part 531 and the first stopper section 541For fulcrum is in circumferential displacement. And, simultaneously in the inside of the second stopper section 542, the second anti-delinking partSlide in 532 spaces that rotate the tubular of the second stopper section 542,532 1 edge, the second anti-delinking part on one side.Thus, straightener(stator) blade 51 keeps relative angle with connecting portion 540 and tilts. So, each rectification leafThe angle of sheet 51 and the inclination of radial inner end correspondingly change. Consequently, straightener(stator) blade 51Phase angle and pitch angle side by side switched. In other words, can rotate by rotating ring 522 if make, withThe first stopper section 541 and the second stopper section 542 shape are separately corresponding, the first anti-delinking part 531Or second anti-delinking part 532 rotate and slide axially, thus the outer end of straightener(stator) blade 51 with respect toThe circumferential relative position of inner end and straightener(stator) blade 51 with respect to orthogonal flat of rotation 9The pitch angle of face is switched simultaneously.
Figure 11, Figure 12, Figure 13 and Figure 14 are the rearviews of switching mechanism 52.
