Description
Technical field
The present invention relates to a kind of air supply devices for blowing out nozzle and having the blowout nozzle.
Background technique
Air supply device is for example built in the various machines such as drying and washing machine, hair dryer, air blower.As hair dryer, example
As hair dryer disclosed in patent document 1 and 2 can be enumerated.
In existing air supply device, the method for reducing air outlet to increase air supply velocity is used.However, when reducing blow-off outlet
When increasing wind speed, the pressure loss blown in wind path increases, and thus generates air-supply loss and air quantity is reduced.In addition, if wind
Amount is reduced, then wind speed can reduce in the identical situation of blowout area.Therefore, research increases wind speed by improving revolution.So
And, as a result, a possibility that increasing there are power consumption increase or noise.
In the case where the air-supply wind path for the shape for being 1 with aspect ratio, the loss blown in wind path is small, but reaches distance
Shorten.In the case where blow-off outlet is elongated shape, though can increase arrival distance, the loss blown in wind path becomes opposite
It is larger.
For example, to drying and washing machine (such as vertical and drum-type) desirably drying time shortening, lower power consumption, dry
Drying quality good (clothing wrinkles are few), laundry damage reduction etc..Moreover, for example, to hair dryer desirably drying time shorten,
Maximization, hair damage reduction of the air quantity of every power consumption etc..It is, when requiring dry to the air supply device with functions/drying
Between shorten, the damage reduction of dried object and high wind speed and air quantity.
In order to which drying is effectively performed, the rectilinear propagation and wind pressure of wind are needed.If although the arrival of wind is arrived apart from short or wind
It reaches but deficiency in draught, is then unable to fully be dried.If can not be sufficiently dry by dried object, the numerous of bacterium be also resulted in
It grows and the growth of smell etc..By make blow-off outlet between dried object at a distance from approach, can thoroughly dry wind be blown to
Part.However, needing very big air outlet to be applied to entire dried object.Moreover, if making blow-off outlet and being done
Distance between dry object is close, then worries to cause to damage to dried object.For example, in hair dryer, it is also proposed that a kind of purport
Increasing wind speed to be conducive to dry nozzle.It it is known that by the way that difference is arranged in the distribution of the blowout speed of wind, it can
Keep wet topknot loose.Though rapid-curing cutback performance is required to drying machine, in order to obtain big effect, it is necessary to which additional part makes structure
Complicate etc..
For example, in patent document 1, multiple segmentation flow paths are divided by the flow path in the nozzle by hair dryer to be arranged,
And so that wet topknot is scattered and shorten drying time, the multiple segmentation flow path, which is clipping the central axis from nozzle, is in
The two sides of the virtual plane of radiated entend setting separate defined width.In this composition, though it can make wind speed that there is big point
Cloth, but in addition to constituting complexity, the pipe range for the flow path as the pressure loss blown in wind path increases, therefore air quantity reduction can not be kept away
Exempt from.
Moreover, multiple chevron convergence pieces are formed in around shape at the nozzle opening of blowout nozzle in patent document 2,
The valley for restraining the mountain portion of the front end of piece and being formed between adjacent mountain portion alternately and to circumferencial direction is equally spaced formed.
Thereby, it is possible to the switching blowout nozzles between convergence state and disperse state.However, only by mountain is arranged in a circumferential direction
The difference of paddy, wind speed profile is limited, and is possible to keep wind speed uniform before reaching hair.

(composition of blowout nozzle)
Then, the more specific composition that the blowout nozzle 30 of first embodiment is directed at while referring to Figure 2 to Figure 4 is said
It is bright.Fig. 2 is into Fig. 4, to indicate that the blowout nozzle 30 of first embodiment (only blows out nozzle from the state that main part 10 is removed
30 figure).
As shown in Figures 2 and 3, blowout nozzle 30 be made of cylinder, the cylinder at one end (side Z2) have be linked to main body
The suction inlet (opening portion) 34 of the blow-off outlet 12 in portion 10 and the other end (side Z1) have blow-off outlet 35.It is opposite to blow out nozzle 30
It can be loaded and unloaded in main part 10.
Suction inlet (opening portion) 34 has substantially circular.It is sent moreover, the inside for constituting the cylinder of blowout nozzle 30 becomes
Wind wind path 30a.Air-supply wind path 30a extends in the main flow direction of wind.Herein, the main flow direction of wind refers to from air supply device
The main blow-off direction of the wind of blow-off outlet (for example, blow-off outlet 12 of the main part 10 of the hair dryer 1) blowout of main body.In Fig. 3
It is indicated by means of an arrow the main flow direction of wind.The main flow direction is the suction plane generally perpendicular direction with suction inlet 34.
Suction inlet 34 is located at the upstream side of the main flow direction of wind.Moreover, blow-off outlet 35 is located at the main flow direction of wind
Downstream side.The cylinder for forming air-supply wind path 30a is respectively provided with the relatively short part of length of main flow direction (it is, short ruler
Very little portion 32) and relatively long part (it is, long size portion 31).Main flow direction is also formed in air-supply wind path 30a as a result,
The relatively short part of length and relatively long part.
Long size portion 31 is with the protruding portion 33 towards the downstream of main flow direction with prominent shape.As shown in Fig. 2 etc.,
The downstream side of protruding portion 33 towards main flow direction is tapered.In the blowout nozzle 30 of present embodiment, long size portion 31 has
There is maximum length L1 (referring to Fig. 3).
The substantially half cycle of short circumferencial direction of the size portion 32 across cylinder and be arranged, have across whole approximately fixed length L2
(referring to Fig. 3).Long size portion 31 has from each end in short size portion 32 gradually protruding portion 33 outstanding forwards.In long size
The forefront portion (end of the side Z1) in portion 31 is provided with top 31a.Moreover, as shown in figure 4, the width (X-direction in long size portion 31
Length) be gradually reduced towards top 31a.
(shape of the air-supply wind path about the arrival distance for increasing wind)
Herein, the loss (loss) to the air quantity in the air-supply wind path of blowout nozzle and the damage from the air quantity after blowout nozzle blowout
Mistake is illustrated.
The loss blown in wind path is according to the sectional area and wet edge length of air-supply wind path (in the main flow of air-supply wind path
On direction, the length of surrounding is surrounded) and change.For example, wet edge length is got over when the sectional area for wind path of blowing is fixed
Long, the frictional resistance of flow path is more, thus the loss blown in wind path increases.That is, when be blow wind path aspect ratio close to 1
Shape and cross sectional shape it is with low uncertainty when, since wet edge length is short, thus have the advantages that blow in wind path lose it is small.
On the other hand, the arrival distance for the air for exporting out from air-supply wind path shortens.Moreover, even if the sectional area of air-supply wind path is solid
Fixed, if air-supply wind path abrupt bend or unexpected width broaden, the flowing of wind can not follow the variation of flow path shape, pressure
Loss increases or causes contraction flow.Therefore, air supply efficiency declines in air-supply wind path.Moreover, if blow-off outlet is set as thin
Long shape, though being then able to extend the arrival distance of blown out wind, the loss blown in wind path becomes relatively large.
In this way, about interfere from blowout nozzle blow out wind arrival apart from the main reason for, (1) can be enumerated by air-supply wind
The reduction of air supply efficiency caused by shape in road, and (2) come out rear wind speed from blowout nozzle and are etched caused air-supply
The decline of ability.
Then, the method for the arrival distance of the wind for improving the blowout in blowout nozzle 30 is illustrated.
The flow velocity of jet flow can decay immediately after the outlet blowout of air-supply wind path.The gesture core of the arrival distance of jet flow and jet flow
Length it is related.In general, it is corroded simultaneously from the jet flow of the outlet outflow of air-supply wind path by the Free Mixing-layer generated from two sides
Reduce, and at a certain distance from disappear.The part is wedge-shaped, and referred to as gesture core.It is freely sprayed what is flowed out into stationary fluid
In the case where stream, the boundary layer of the outlet shapes of the length of gesture core according to air-supply wind path, the outlet wall along air-supply wind path
State, original vortex etc. and it is different, but as the length of the gesture core increases, the arrival distance of jet flow can extend.
Therefore, in the air-supply wind path 30a of the blowout nozzle 30 of present embodiment, the wall configuration of blow-off outlet 35 is carried out
Design, and new energy is assigned to the boundary layer of the wall surface along blow-off outlet 35.Thereby, it is possible to extend the gesture core of jet flow, and
It is able to suppress the decaying of flow velocity.Therefore, compared with existing, the arrival distance of the wind (fluid) blown out from blowout nozzle 30 extends.
In the aspect for requiring air supply device to take into account Wind Volume and high wind speed, the blow-off outlet of round inhibits air quantity to reduce,
On the other hand, wind speed reduces.When blow-off outlet is configured to elongated shape, wind speed increases but air quantity is reduced, and the range of air-supply
It is limited to elongated shape.By the main part 10 of hair dryer 1 inside the wind generated by wind pushing mechanism from the blow-off outlet of main part 10
12 flow into the suction inlet 34 of blowout nozzle 30, and further along the medial surface flow direction blowout nozzle 30 of air-supply wind path 30a
Blow-off outlet 35.
According to the composition of blowout nozzle 30, the front with the wind along long size portion 31 narrows, and wind is along the shape to narrow
The width reduction of shape and wind, thus air quantity is gradually converted to wind speed, and wind speed is increasing.As a result, from the long size portion 31 of formation
The top 31a of protruding portion 33 generate longitudinal turbulence ingredient (referring to Fig. 3).The longitudinal turbulence ingredient of wind can be to mentioning in boundary layer
For new kinetic energy, wind can be made to reach farther place by rotation.Moreover, because the decaying of longitudinal turbulence ingredient is slow, institute to prevent
Only main flow is guided air-flow erosion, is easy to maintain gesture core (wind components) separate.It is acted on by these, is sprayed from blowout
The flow velocity for the high speed ingredient (high speed portion) in wind that mouth 30 is blown out subtracts to decline and is inhibited by longitudinal turbulence.
Moreover, being able to maintain that along the wind in the short size portion 32 in the air-supply wind path 30a of blowout nozzle 30 to suction inlet 34
Wind speed when inflow, and sent out without loss as the wind comprising Wind Volume ingredient (Wind Volume portion) at this location.
As previously discussed, blowout nozzle 30 according to the present embodiment, can generate in the case where not damaging Wind Volume
High speed winds and the wind for blowing out hair dryer 1.Moreover, because the shape for blowing out the blow-off outlet 35 of nozzle 30 is not set as elongated shape,
So blowing range can be made relatively large.
Therefore, hair dryer 1 according to the present embodiment can reduce the wind loss in air-supply wind path, and extend wind
Reach distance.Moreover, in the hair dryer 1 of present embodiment, by installing blowout nozzle 30 to main part 10, strong wind can be blown out
The wind of amount and high wind speed.Therefore, when being able to suppress the addition of the part in main part 10 and the complication of structure, and shortening dry
Between.
< second embodiment >
Then, second embodiment of the present invention is illustrated.In second embodiment, the composition and the of nozzle 130 is blown out
One embodiment is different.About composition in addition to this, composition same as the first embodiment can be applied.Therefore, hereinafter,
It is illustrated centered on the composition being different from the first embodiment.
Fig. 5 shows the appearance of the blowout nozzle 130 of second embodiment into Fig. 7.The blowout nozzle of present embodiment
130 in the same manner as first embodiment, is installed to the main part 10 of hair dryer 1 and uses.Fig. 5 is into Fig. 7, from main part
10 states removed indicate blowout nozzle 130 figure of nozzle 130 (only blow out).
Blowout nozzle 130 is made of cylinder, which has the blow-off outlet 12 for being linked to main part 10 at one end (side Z2)
Suction inlet (opening portion) 34 and the other end (side Z1) have blow-off outlet 35.Blowing out nozzle 130 can be relative to main part
10 handling.
Suction inlet (opening portion) 34 has substantially circular.It is sent moreover, the inside for constituting the cylinder of blowout nozzle 130 becomes
Wind wind path 130a.Air-supply wind path 130a extends in the main flow direction of wind.The cylinder for forming air-supply wind path 130a is respectively provided with
The relatively short part of the length of main flow direction (it is, short size portion 32) and relatively long part are (it is, long size portion
131)。
Long size portion 131 is with the protruding portion 133a and 133b towards the downstream of main flow direction with prominent shape.Such as
Shown in Fig. 5 etc., in present embodiment, there are two protruding portion 133a and 133b for setting.Between two protruding portions 133a and 133b
Form valley 133c.The flowing of the wind in the air-supply wind path 130a of blowout nozzle 130 is indicated by means of an arrow in Fig. 7.Moreover, in Fig. 7
Show the speed point of the wind of each section (protruding portion 133a and 133b and valley 133c) blowout along long size portion 131
Cloth.
It blows out in nozzle 130, is formed there are two protruding portion, there through long 131 side of size portion in air-supply wind path 130a
Wind be divided into two parts.As shown in fig. 7, passing through the speed of the wind of long 131 side of size portion in each of protruding portion 133a and 133b
Near top becomes maximum.Moreover, generating longitudinal turbulence respectively at this point, branching into two-part high speed winds (referring to Fig. 7).By
This, the arrival distance of wind becomes longer.
The projected direction of two protruding portions 133a and 133b shown in Fig. 7 are tilted than main flow direction gently towards center.?
It is exactly that each protruding portion 133a and 133b is not parallel each other, but with towards the downstream side of main flow direction, it is close to each other
Direction is prominent.It is blown out slightly inwardly along the wind that each protruding portion 133a and 133b flows as a result,.These are branched to two-part
High speed winds cross near downstream side, and thus the maximum wind velocity in downstream side further increases.Even if being generated in a protruding portion high
Fast wind, some erosion that high speed winds also can be slow by wind speed, crosses in downstream side but if branching into two-part high speed winds, then damages
It loses (erosion) and is less than the high speed winds only generated in a protruding portion, thus obtain higher wind speed.
Moreover, the speed of the wind (it is, near valley 133c) two the protruding portions 133a and 133b with wear
The wind facies for crossing the top of protruding portion 133a and 133b is smaller (referring to Fig. 7).In this way, according to the composition of blowout nozzle 130, it can
Biggish unevenness is set in wind speed profile.Thereby, it is possible to improve the effect for making the dispersions such as wet topknot.
Moreover, as shown in figure 5, long size portion 131 accounts on the circumferencial direction of the air-supply wind path 130a of blowout nozzle 130
According to the range B that occupies of range A and short size portion 32 each about half.Moreover, between long size portion 131 and short size portion 32
It connects smoothly.
According to this constitution, function and short size portion by the high speed of the wind in about half ground long size portion 131 of division
The function of strong wind quantization in 32, can be with well balanced model split Wind Volume portion and high wind speed portion.Moreover, in high speed portion
It can be realized the further raising of wind speed, further strong wind can be promoted to quantify in Wind Volume portion.
Moreover, the wind passed through in air-supply wind path 130a is flowed along the wall surface of air-supply wind path 130a.Therefore, because air-supply wind
Wall surface in the 130a of road is smoothly formed, and is able to suppress the degree of air quantity reduction.
Herein, on one side referring to Fig. 8 to Figure 12, on one side to the area (inhalation area X (ginseng of the suction inlet 34 of blowout nozzle 130
According to Fig. 8)) it is illustrated with the ratio between the area of blow-off outlet 35 (blowout area Y (referring to Fig. 9 (b))).
In addition, blowout area Y is defined as, by the entire periphery of blow-off outlet 35 (it is, the blowout of blowout nozzle 130
The entire periphery of the end of side) the most downstream position of blowout nozzle 130 is projected to (it is, each protruding portion 133a and 133b
Top) at the resulting shape in the face vertical with the main flow direction of wind area.The mainstream of wind indicated by an arrow in Fig. 9 (a)
Dynamic direction.The main flow direction is the suction plane generally perpendicular direction with suction inlet 34.
Figure 10 is shown into Figure 12 when the area ratio of inhalation area X occurs respectively for blowout area Y in blowout nozzle 130
Wind speed, air quantity and the measurement result of drying time when kind change.The wind speed (m/s) of hair dryer 1 is shown in Figure 10 for face
Variation of the product than Y/X.Air quantity (the m of hair dryer 1 is shown in Figure 113/ minute) variation for area ratio Y/X.Figure 12 is table
Show curve graph of the drying time (minute) for the variation of area ratio Y/X of hair dryer 1.Conduct is also shown into Figure 12 by Figure 10
Cylindrical shape is installed in the case where 10 monomer of main part (no nozzle) using hair dryer 1 of comparison other and in main part 10
Nozzle in the case where result.
It can be confirmed according to these results, by the way that blowout area Y is set as 0.6 or more 1.3 for the area ratio of inhalation area X
In following range, drying time it can will shorten 5% or more.And confirm, in blowout nozzle 130, and nozzle is not installed
The case where (3.85 minutes) compare, when area ratio Y/X is set as 0.9, the drying time (3.17 minutes) of hair dryer 1 can shorten
15%.
As described above, according to the hair dryer 1 for the blowout nozzle 130 for being equipped with present embodiment, it can flow into and send
The speed of wind in wind wind path 130a is different according to the position in air-supply wind path 130a.Therefore, wet topknot can be made to scatter, and
