For being equipped with the air conditioner room unit of the wind deflector, and the air conditioner including the air conditioner room unit.It should be noted that institute
Stating air conditioner room unit can be on-hook, be also possible to cabinet-type air conditioner.
In embodiments of the present invention, as shown in Figure 1 to Figure 3, wind deflector 10 has windward side 11 and air side 12, Yi Jixiang
On wind-guiding face 13.The wind deflector 10 includes the first air dam 10a and the second air dam 10b, wherein first air dam
The edge 10a is controlled to extension.The second air dam 10b includes the first sub- wind deflector 10b1With the second sub- wind deflector 10b2, described
One sub- wind deflector 10b1With the described second sub- wind deflector 10b2In left and right to being arranged alternately and being mutually linked, wherein one described first
Sub- wind deflector 10b1It is connected with the first air dam 10a, and each first sub- wind deflector 10b1Windward side 11 backwards
The first air dam 10a is reversed downwards.
Wind deflector 10 is mounted to the air outlet of air conditioner room unit, and wind deflector 10 has two opposite plate faces,
In the generally curved setting of a plate face, wind deflector 10 mainly by the arc plate face implement wind-guiding, i.e., the plate face be wind-guiding face 13 (for
Facilitate statement, define wind-guiding face 13 upwards, the back side of wind-guiding face 13 is downward, the length direction of wind deflector 10 be left and right to).And
And lug 10c is installed in the wind-guiding face 13, it is provided with crown of roll 10d on the lug 10c, the motor positioned at air outlet side
It is connect by connecting rod with crown of roll 10d, so as to drive wind deflector 10 in air outlet varus transduction wind.In addition, working as wind deflector
10 at air outlet when wind-guiding, and the side for first contacting air-flow (air-flow of tubular wine wheel blowout) is windward side 11, with the side
Opposite the other side is air side 12；Air-flow is blown out after windward side 11, via wind-guiding face 13 from air side 12.
First wind deflector 10b1Have multiple, quantity can be 2,3,4 or more, the second wind deflector 10b2Number
Amount can be 1,2,3 or more.Order the first wind deflector be X, the second wind deflector be Y, the two left and right to alternating row
Mode for cloth is XYX perhaps XYXY ... XY or XYXY ... YX.It is, the end of the second air dam 10b can be the first son
Wind deflector 10b1, at this point, the first sub- wind deflector 10b1Quantity wind deflector 10b than second2Quantity more one；Certainly, second
The end of air dam 10b can be the second sub- wind deflector 10b2, at this point, the first sub- wind deflector 10b1Quantity and the second sub- wind-guiding
Plate 10b2Quantity it is identical.
Second sub- wind deflector 10b2It is and the first sub- wind deflector 10b1Linking, and controlling to extension.Certainly, the second son
Wind deflector 10b2Extension mode can be concordant with the extending direction of the first air dam 10a, be also possible to slightly towards updip
Tiltedly, it can also slope slightly downward.
In the air duct of air conditioner room unit, due to tubular wine wheel blowout airflow direction be it is certain, led for first
For wind portion 10a, wind deflector 10 is in switching process, only at the beginning of the windward side 11 of the first air dam 10a is turned to air-flow
When beginning direction is substantially concordant, the wind-guiding direction of the first air dam 10a is just consistent with the inceptive direction of air-flow, and windage at this time is most
Small, air output is maximum.
Wind deflector 10b for first1For, due to its own torsion, thus, windup-degree is with itself and the first wind-guiding
The increase of the distance between portion 10a and be gradually increased.So when wind deflector 10 is overturn, although airflow direction can not constantly
It is concordant with the first air dam 10a, still, due to the first sub- wind deflector 10b1With certain windup-degree, when the first air dam
When the windward side 11 of 10a is downwardly turned over from the inceptive direction flush position of itself and air-flow, although the first air dam 10a not with
The inceptive direction of air-flow is concordant.But the first sub- wind deflector 10b1, within the scope of its windup-degree α, windward side 11 is at least
Part can be constantly substantially concordant with the inceptive direction of air-flow, to reduce windage, and then air output can be improved.
In addition, due to the second sub- wind deflector 10b2With the first sub- wind deflector 10b1End (far from the first air dam 10a
One end) linking, so, relative to the first sub- wind deflector 10b1For, the second sub- wind deflector 10b2It is equivalent to and continues the first sub- wind-guiding
Plate 10b1Maximum twist angle (with the second sub- wind deflector 10b2Left and right to extending direction concordant with the first air dam 10a be
Example).When the overturning of wind deflector 10 to the second sub- wind deflector 10b2When consistent with the initial flow direction of air-flow, entire second sub- wind deflector
10b2Wind-guiding face 13 will be with air flow contacts, at this point, more air-flow can pass through the second sub- wind deflector 10b2Blowout, thus, gas
The windage of stream can achieve minimumization.It is, when the windward side 11 of the first air dam 10a is flat with the inceptive direction of air-flow from it
When neat position downwardly turns over, fraction is by the abut the first air dam 10a first sub- wind deflector 10b1Blowout, at this point, blowout
Gas-flow resistance reduce, air quantity is larger.When wind deflector 10 continues overturning, with the first sub- wind deflector 10b1Second son of linking
Wind deflector 10b2 wind-guiding, gas-flow resistance is lower at this time, and air quantity is bigger.Similarly, when wind deflector 10a continues overturning, air quantity can be slightly
It edges down low, then increases suddenly, so recycle.
Technical solution of the present invention by by wind deflector 10 in left and right to being divided into the first air dam 10a and the second air dam 10b,
Second air dam 10b divides first be arranged alternately sub- wind deflector 10b again1With the second sub- wind deflector 10b2, also, the first sub- wind-guiding
Plate 10b1It is reversed downwards backwards to the first air dam 10a, so as to so that the first sub- wind deflector 10b1Model is reversed with certain angle
It encloses；During 10 wind-guiding of wind deflector, due to the presence of the angle slew range, so, wind deflector 10 can be kept certain
Slewing area in, the first sub- wind deflector 10b1Windward side always have the position concordant with the inceptive direction of air-flow, to drop
It is low go out wind resistance, and then improve air output.In addition, due to the first sub- wind deflector 10b1 torsion, the second sub- wind deflector 10b2
It is connected with the first sub- wind deflector 10b1 and along left and right to extension, is equivalent to the second sub- wind deflector 10b2 and has continued the first sub- wind deflector
The maximum twist angle of 10b1, so, air-flow is by the second sub- wind deflector 10b2When outflow, resistance can be minimized, thus more
Windage has further been dropped, air output is improved, furthermore, since the second air dam 10b has multiple folding faces, multiple folding faces are promoting wind
While amount, outlet air can be oriented to multiple directions, expand air-out area, reduce wind velocity out, so that wind is softer, weakened
The intensity of air-conditioner wind blow-through promotes user's impression of calm sense.
Referring to Fig. 2, in above-described embodiment, the first sub- wind deflector 10b1Windward side 11 reverse downwards, and first son
Wind deflector 10b2Air side 12 can be with the first sub- wind deflector 10b1The torsion of windward side 11 upwarps, can also be with the first air dam
10a keeps concordant.
Here, considering: if the first sub- wind deflector 10b1Air side 12 it is concordant with the first air dam 10a holding, that
, on the one hand, the first sub- wind deflector 10b1Air side 12 bear stress it is larger, it is easy to crack after being impacted；On the other hand
Also it is unfavorable for being manufactured for wind deflector 10.
Furthermore the first sub- wind deflector 10b1Air side 12 upwarp the whole air outlet angle that can increase wind deflector 10, use
Family may stand in indoor same position, persistently can experience air-flow in a long time.
Finally, the first sub- wind deflector 10b1Air side 12 upwarp, can be by gas for the first air dam 10a
Stream, which is more likely to put down, blows (or blowing upwards), in this way, it is empty to blow to indoor upper layer by the air-flow that the second air dam 10b is blown out
Between, the feeling of cold wind blow-through can be reduced, meanwhile, this part cold air can slowly decline, it can be achieved that the canopy of the heavens under the effect of gravity
Refrigeration, comfortable better effect.
Referring to Fig. 3 and Fig. 4, in above-described embodiment, the second air dam 10b is relative to the first air dam 10a's
Maximum twist angle cannot be too small, otherwise, is promoted to air quantity ineffective.Certainly, the maximum twist angle of the second air dam 10b
Degree can not be excessive, otherwise, influence 10 overall construction of wind deflector (for example, wind deflector 10 it is whole left and right to consistency it is too poor,
Air outlet needs to stop space to wind deflector 10, otherwise in its switching process, may interfere with other component).In this implementation
In example, the second air dam 10b is more than or equal to 5 ° relative to the maximum twist angle of the first air dam 10a and is less than or equal to
30 ° (such as: 5 °, 10 °, 15 °, 20 °, 25 °, 30 ° etc.).
Referring to Figures 1 and 2 since the main function of wind deflector 10 is the air-out direction for changing air-flow, if the second air dam
10b occupies the most of region of wind deflector 10, then, it is ineffective to the change of airflow direction.So in the present embodiment, being
Guarantee the wind effect of wind deflector 10, the second air dam 10b left and right to length should occupy entire wind deflector 10a
It is preferred in left and right to the sub-fraction of length.Here, the first air dam 10a left and right to length be L1, the second air dam 10b
Left and right to length be L2, wherein L2/L1∈ [0.1,0.4].Such as: L2/L1=0.2,0.3 etc..
Furthermore, it is contemplated that the principal element for reducing windage depends on the first sub- wind deflector in the second air dam 10b
10b1, so, the first sub- wind deflector 10b1Left and right to length need to select suitable range.In the present embodiment, Ge Gesuo
State the first sub- wind deflector left and right to length be d1、d2、d3、d4…dn, d1+d2+d3+d4…+dn=d0, wherein d0/L2∈
[0.2,0.8].Such as d0/L2=0.4,0.5,0.6 etc..In identical windup-degree, if d0/L2Be worth it is relatively low, inevitable the
One sub- wind deflector 10b1Windup-degree is steeper, in this way, the first sub- wind deflector 10b1Less than normal, the wind effect with the contact area of air-flow
It is poor, by the first sub- wind deflector 10b1The throughput of outflow is also less than normal.If d0/L2Be worth it is higher, then inevitable first sub- wind deflector
10b1It is longer, on the contrary, the second sub- wind deflector 10b2It is shorter, by the second sub- wind deflector 10b2The throughput of outflow is less than normal, and then overall
Air output can reduce.
Air duct inner sidewall (positioned at air duct or so to inner sidewall) be affected to air-flow velocity, close to air duct or so two
In a inner sidewall regional scope, closer to the air-flow of inner sidewall, flow velocity is smaller.Referring to figs. 1 to Fig. 3, if the second air dam
The end of 10b is the first sub- wind deflector 10b1, since it is reversed downwards, it is clear that by the first sub- wind deflector 10b1The throughput of outflow
Less, more air-flows can be influenced with by air duct inner sidewall.If the end of the second air dam 10b is the second sub- wind deflector
10b2, that is, the first sub- wind deflector 10b1With the described second sub- wind deflector 10b2Quantity it is identical, when wind deflector 10 rotate
To the second sub- wind deflector 10b2Air-out direction it is consistent with air-flow inceptive direction when, due to the second sub- wind deflector 10b2Be it is straight,
So the air-flow in air duct inner sidewall regional scope, bigger a part can be directly by the second sub- wind deflector 10b2Blowout,
Windage substantially reduces.
Referring to Fig. 4, the windward side 11 of the first sub- wind deflector 10b1 has one controlling to the side of extension, defines the side
Far from the first air dam 10b one end be P point (windup-degree of P point is in the first sub- wind deflector 10b1Upper maximum), definition
The side is Q point close to one end of the first air dam 10a (windup-degree of Q point is minimum on the first sub- wind deflector).At this
There is dynamic point K, K a point to be moved in Q point process on side from P point, K point relative to Q point windup-degree to gradually decreasing,
Finally when K point is moved to Q point, the corresponding windup-degree of K point is minimized.
Windup-degree of the K point relative to Q point, accounting for P point relative to the percentage of the windup-degree of Q point is y (such as P point phase
Windup-degree for Q point is 10 °, and K point is 5 ° relative to the windup-degree of Q point, at this point, 50%) y takes.
K point and P point are defined in left and right at a distance from, account for P point and Q point left and right to the percentage of spacing be x (for example, K
Point and P point are 2cm at a distance from left and right, P point and Q point left and right to spacing be 4cm, at this time 50%) x takes, here, y is with x
Increase and be gradually reduced.Y, which can be, linearly to successively decrease with x linear correlation, that is, y with the increase of x.Certainly, y can be with
It can be the curved line relations such as conic section, sine or cosine with the relationship of x, it is, y curved successively decreases with the increase of x.
Referring to table 1 and Fig. 5, the relationship of y and x may is that y=-x+1 for linear correlation in above-described embodiment,
In this way, the first sub- wind deflector 10b1Angle reverse the trend and be unlikely to also to be unlikely to put down suddenly.Because of the first sub- wind deflector 10b1
Left and right to length it is certain in the case where, will lead to that wind deflector 10 is whole to need to occupy biggish rotation space suddenly excessively, it is excessively flat
Air quantity can be promoted ineffective.
The relationship of y and x can also be y=-xc1+1(c1At ∈ (1 ,+∞)) for such situation, for example, y=-x2+ 1,
Increase with x, y reduces amplitude for straight line, and beginning is smaller, and the later period is larger.It is, the angle of the first sub- wind deflector 10b1
Degree torsion is first smooth, after it is relatively steep.In this way, the second air dam 10b is connected preferably with the first air dam 10a, the first air dam 10a with
Second junction air dam 10b stress is smaller, not easily damaged.
The relationship of y and x can also be y=-xc2+1(c2In ∈ (0,1)), such as y=-x0.5+ 1, for such situation, with
X increases, and y reduces amplitude for straight line, and beginning is larger, and the later period is smaller.In this way, the first sub- wind deflector 10b1Effect windward
Fruit is preferable, and air quantity is bigger.
In 10 rotation process of wind deflector, for y with the increase of x curved the case where successively decreasing, the first son can be made to lead
Aerofoil 10b1It can be constantly substantially concordant with air-flow inceptive direction with more large area.To the promotion significant effect of air quantity.
Together referring to Fig. 6, in a further preferred embodiment, y and x relationship can also be y=0.5cos (x π)+0.5.Such as
This, which has both above-mentioned y=-xc1+ 1 and y=-xc2+ 1 beneficial effect.Namely first sub- wind deflector 10b1Not only after
It has held and has been connected the smoother and lesser effect of resistance with the first air dam 10a, moreover, also inheriting the effect of excellent effect windward
Fruit.Furthermore it is curved when successively decreasing with the increase of x also to inherit y, the first sub- wind deflector 10b1It can be constantly with more large area
The advantage substantially concordant with air-flow inceptive direction, thus, air output is greatly improved in synthesis.
