Air conditioner room unit for being provided with the wind deflector, and the air conditioner including the air conditioner room unit.It should be noted that institute
It can be on-hook or cabinet-type air conditioner to state air conditioner room unit.
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
10a is along left and right 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 first described in one
Sub- wind deflector 10b1It is connected with the first air dam 10a, and each first sub- wind deflector 10b1Windward side 11 dorsad
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 relative plate faces, its
In a plate face is generally curved sets, wind deflector 10 is main, and to implement wind-guiding, the i.e. plate face by the arc plate face be that wind-guiding face 13 (is
Convenient statement, defines wind-guiding face 13 upwards, the back side of wind-guiding face 13 downwards, the length direction of wind deflector 10 for left and right to).And
And, it is provided with the wind-guiding face 13 on lug 10c, the lug 10c and is provided with crown of roll 10d, the motor positioned at air outlet side
It is connected 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 sidepieces for contacting air-flow (air-flow of tubular wine wheel blowout) during wind-guiding, first at air outlet are windward side 11, with the sidepiece
Relative 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, its quantity can be 2,3,4 or more, the second wind deflector 10b2Number
Amount can be 1,2,3 or more.The first wind deflector is ordered for X, the second wind deflector is Y, the two left and right to alternating arrange
Mode for cloth is XYX, either XYXY ... XY or XYXY ... YX.It is, the second air dam 10b end can be the first son
Wind deflector 10b1, now, the first sub- wind deflector 10b1Quantity wind deflector 10b than second2Many one of quantity；Certainly, second
Air dam 10b end can be the second sub- wind deflector 10b2, now, 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 in left and right to extension.Certainly, the second son
Wind deflector 10b2Extension mode can be concordant with the first air dam 10a bearing of trend or slightly towards updip
Tiltedly, it can also slope slightly downward.
In the air channel of air conditioner room unit, because the airflow direction that tubular wine wheel is blown out is certain, led for first
For wind portion 10a, wind deflector 10 in switching process, only the first air dam 10a windward side 11 turn to at the beginning of air-flow
Beginning direction it is substantially concordant when, the first air dam 10a wind-guiding direction is just consistent with the inceptive direction of air-flow, and windage now is most
Small, air output is maximum.
For the first sub- wind deflector 10b1For, due to its own torsion, so that, its windup-degree is with itself and the first wind-guiding
The distance between portion 10a increase and gradually increase.So, when wind deflector 10 is overturn, although, airflow direction can not possibly be 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
10a windward side 11 from the inceptive direction flush position of itself and air-flow downwardly turn over when, although the first air dam 10a not with
The inceptive direction of air-flow is concordant.But, the first sub- wind deflector 10b1 is in the range of its windup-degree α, and its windward side 11 is at least
Inceptive direction that partly can be constantly with air-flow is substantially concordant, so as to reduce windage, and then can improve air output.
Further, since the second sub- wind deflector 10b2With the first sub- wind deflector 10b1End (away from the first air dam 10a
One end) linking, so, wind deflector 10b relative to first1For, the second sub- wind deflector 10b2Equivalent to the first sub- wind-guiding of continuity
Plate 10b1Maximum twist angle (with the second sub- wind deflector 10b2Left and right to bearing of trend concordant with the first air dam 10a be
Example).When wind deflector 10 is overturn to the second sub- wind deflector 10b2When consistent with the initial flow direction of air-flow, whole second sub- wind deflector
10b2Wind-guiding face 13 will be with air flow contacts, now, more air-flows can pass through the second sub- wind deflector 10b2Blowout, so that, gas
The windage of stream can reach minimumization.It is, when the first air dam 10a windward side 11 is put down from the inceptive direction of itself and air-flow
When neat position is downwardly turned over, fraction is by the abut the first air dam 10a first sub- wind deflector 10b1Blowout, now, blowout
Gas-flow resistance reduction, air quantity is larger.When wind deflector 10 continues to overturn, with the first sub- wind deflector 10b1Second son of linking
Wind deflector 10b2 wind-guidings, now gas-flow resistance is lower, and air quantity is bigger.Similarly, when wind deflector 10a continues to overturn, air quantity can be slightly
Edge down low, then increase suddenly, so circulation.
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 10b1Dorsad the first air dam 10a is reversed downwards, so as to so that the first sub- wind deflector 10b1Model is reversed with certain angle
Enclose；During the wind-guiding of wind deflector 10, 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, so as to drop
It is low to go out wind resistance, and then improve air output.Further, since the first sub- wind deflector 10b1 is reversed, the second sub- wind deflector 10b2
It is connected with the first sub- wind deflector 10b1 and along left and right to extension, wind deflector 10b2 equivalent to second has continued the first sub- wind deflector
10b1 maximum twist angle, so, air-flow is by the second sub- wind deflector 10b2During outflow, its resistance can be minimized, so that more
Windage has further been dropped, air output is improved, furthermore, because the second air dam 10b has multiple folding faces, multiple folding faces are in lifting wind
While amount, air-out can be oriented to multiple directions, expand air-out area, reduce and wind velocity so that wind is softer, weakened
The intensity of air-conditioner wind blow-through, lifts user's impression of calm sense.
In reference picture 2, 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 10b1Windward side 11 is reversed and upwarped, 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 holdings, that
, on the one hand, the first sub- wind deflector 10b1The stress that bears of air side 12 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 and can increase the overall air outlet angle of wind deflector 10, use
Family may stand in indoor same position, can persistently 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, the upper strata that can blow to interior by the second air dam 10b air-flows blown out is empty
Between, the sensation of cold wind blow-through can be reduced, meanwhile, this part cold air can slowly decline under gravity, and the canopy of the heavens can be achieved
Refrigeration, it is comfortable better.
In reference picture 3 and Fig. 4, above-described embodiment, the second air dam 10b is relative to the first air dam 10a's
Maximum twist angle can not be too small, otherwise, and the effect lifted to air quantity is not good.Certainly, the second air dam 10b maximum twist angle
Degree can not be excessive, otherwise, influence wind deflector 10 unitary construction (for example, wind deflector 10 it is overall left and right to uniformity it is too poor,
Air outlet needs to stop space to wind deflector 10, otherwise in its switching process, may interfere with miscellaneous part).In this implementation
In example, maximum twist angles of the second air dam 10b relative to the first air dam 10a is more than or equal to 5 ° and is less than or equal to
30 ° (for example：5 °, 10 °, 15 °, 20 °, 25 °, 30 ° etc.).
Referring to Figures 1 and 2 because the main function of wind deflector 10 is the air-out direction of change air-flow, if the second air dam
10b occupies the most of region of wind deflector 10, then, the change effect to airflow direction is not good.So, in the present embodiment, it is
Ensure the wind effect of wind deflector 10, the second air dam 10b left and right to length should occupy whole 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 in the second air dam 10b, the principal element of reduction windage depends on the first sub- wind deflector
10b1, so, the first sub- wind deflector 10b1Left and right to length need to select suitable scope.In the present embodiment, each institute
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 the case of identical windup-degree, if d0/L2Value is relatively low, and inevitable the
One sub- wind deflector 10b1Windup-degree is steeper, in this way, the first sub- wind deflector 10b1Contact area with air-flow is less than normal, wind effect
It is poor, by the first sub- wind deflector 10b1The throughput of outflow is also less than normal.If d0/L2Value 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 be reduced.
Air channel madial wall (be located at air channel or so to madial wall) influences larger to air-flow velocity, close to air channel or so two
In individual madial wall regional extent, closer to the air-flow of madial wall, its flow velocity is smaller.Referring to figs. 1 to Fig. 3, if the second air dam
10b end is the first sub- wind deflector 10b1, because it is reversed downwards, it is clear that by the first sub- wind deflector 10b1The throughput of outflow
Less, more air-flows can be with being influenceed by air channel madial wall.If the second air dam 10b end is the second sub- wind deflector
10b2That is, the first sub- wind deflector 10b1With the described second sub- wind deflector 10b2Quantity it is identical, when wind deflector 10 is rotated
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 the madial wall regional extent of air channel, a bigger part can be directly by the second sub- wind deflector 10b2Blowout,
Windage is substantially reduced.
Reference picture 4, the first sub- wind deflector 10b1 windward side 11 have one in left and right to the side of extension, define the side
(windup-degree of P points is in the first sub- wind deflector 10b for P points one end away from the first air dam 10b1Upper maximum), definition
The side is Q points (windup-degree of Q points minimum on the first sub- wind deflector) close to the first air dam 10a one end.At this
On side have dynamic point K, K a point in Q point process is moved to from P points, K points relative to Q points windup-degree to gradually reducing,
Finally when K points are moved to Q points, the corresponding windup-degree of K points is minimized.
K points are relative to the windup-degree of Q points, and the percentage for accounting for windup-degree of the P points relative to Q points is y (such as P point phases
Windup-degree for Q points is 10 °, and K points are 5 ° relative to the windup-degree of Q points, and now, 50%) y takes.
Define K points and P points left and right to distance, account for P points and Q points left and right to the percentage of spacing be x (for example, K
Point and P points left and right to distance be 2cm, P points and Q points left and right to spacing be 4cm, now 50%) x takes, here, y is with x
Increase and be gradually reduced.Y can linearly be successively decreased with x increase with x linear correlations, that is, y.Certainly, y can be with
The curved line relations such as the relation with x can be conic section, sinusoidal or cosine, it is, y curved successively decreases with x increase.
Y and x relation in reference table 1 and Fig. 5, above-described embodiment, for linear correlation, Ke Yishi：Y=-x+1,
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 the first sub- wind deflector 10b1
Left and right to length it is certain in the case of, can cause wind deflector 10 is overall to need to occupy larger rotation space suddenly excessively, it is excessively flat
Effect can be lifted to air quantity not good.
Y and x relation can also be y=-xc1+1(c1In ∈ (1 ,+∞)) for such a situation, for example, y=-x2+ 1,
Increase with x, y reduces amplitude for straight line, and beginning is smaller, and the later stage is larger.It is, the first sub- wind deflector 10b1 angle
Degree reverse first it is smooth, after it is steeper.In this way, the second air dam 10b is connected preferably with the first air dam 10a, the first air dam 10a with
Second air dam 10b junctions stress is smaller, not easily damaged.
Y and x relation can also be y=-xc2+1(c2In ∈ (0,1)), such as y=-x0.5+ 1, for such a situation, with
X increases, and y reduces amplitude for straight line, and beginning is larger, and the later stage is smaller.In this way, the first sub- wind deflector 10b1Effect windward
Preferably, air quantity is bigger for fruit.
In the rotation process of wind deflector 10, for y with x increase the curved in the case of of successively decreasing, can lead the first son
Aerofoil 10b1Can be constantly substantially concordant with air-flow inceptive direction with more large area.So as to which the lifting effect to air quantity is notable.
Reference picture 6 in the lump, in a further preferred embodiment, y can also be y=0.5cos (x π)+0.5 with x relationship.Such as
This, the curve has above-mentioned y=-x concurrentlyc1+ 1, and y=-xc2+ 1 beneficial effect.Namely first sub- wind deflector 10b1Not only after
Hold and be connected the smoother and less effect of resistance with the first air dam 10a, moreover, also inheriting the effect of excellent effect windward
Really.Furthermore, it is curved when successively decreasing with x increase also to inherit y, the first sub- wind deflector 10b1Can be constantly with more large area
With air-flow inceptive direction substantially concordant advantage so that, it is comprehensive on greatly improve air output.
The y values of each function of table 1 and x value corresponding tables
