Embodiment 1
The present embodiment provides a kind of air-conditioning internal machine wind deflector, including wind deflector main body 1, wind deflector main body 1 is equipped with noise reduction
Hole 11 and cavity 12, cavity 12 are connected to noise reduction hole 11, and wind deflector main body 1 includes rear narrow side 13, and rear narrow side 13 is wind-guiding
Narrow side on 1 length direction of plate main body, noise reduction hole 11 are located in rear narrow side 13.
The lesser rectangular plate-like structure of the generally thickness of wind deflector main body 1 has four narrow sides, and two of them are in wind deflector
On the length direction of main body 1, two other is in the width direction of wind deflector main body 1, in the case where ignoring its thickness, wind-guiding
Plate ontology 1 is just a rectangle, and the longer sides direction of rectangle is the length direction of wind deflector main body 1, the shorter edge institute of rectangle
It is the width direction of wind deflector main body 1 in direction.After wind deflector main body 1 is installed on indoor unit, when it is at work
When full open position, the narrow side of length direction of the wind deflector main body 1 at air outlet of indoor set is rear narrow side 13.In conjunction with
Shown in Fig. 1-3, in the present embodiment, wind deflector main body 1 is elongated rectangular hollow plate structure, and hollow space is cavity
12, in the rear narrow side 13 of the length direction of wind deflector main body 1 be equipped with several noise reduction holes 11, each noise reduction hole 11 with
Cavity 12 is directly connected to.
In this way, the air-flow blown in the rear narrow side 13 of wind deflector main body 1 is entered in cavity 12 by noise reduction hole 11, cavity
Gas in 12 mutually liquidates with the air generation being blown into noise reduction hole 11, cuts down the sound energy of air-flow, effectively reduces outlet air
Noise.
When indoor mechanism cold or heating, wind deflector main body 1 is opened, and rear narrow side 13 is close to air outlet, so that from going out
The air of air port blowout can flow through the rear narrow side 13 of wind deflector main body 1, since rear narrow side 13 is equipped with several noise reduction holes 11,
Portion of air can flow into noise reduction hole 11, lead between the cavity 12 of wind deflector main body 1 and outer wall that there are non-uniform pressure point
Cloth, this non-uniform pressure is distributed changeable gas speed, therefore can weaken air-flow to a certain extent for leading
The impact on 1 surface of aerofoil main body reduces noise；Meanwhile from the air-flow that noise reduction hole 11 is blown into cavity 12 in cavity 12 shape
At round-trip flowing, and the rubbing action that this round-trip flowing generates disappears the energy to air-flow, and also can achieve reduces noise
Effect.
Further, the narrow side far from the length direction at air outlet when wind deflector main body 1 being in full open position
As leading edge narrow side 14, two sides and the leading edge narrow side 14 of the width direction of wind deflector main body 1 are sealed.In this way, from noise reduction
Hole 11 is blown into the air-flow in cavity 12 and forms round-trip flowing in cavity 12, and the rubbing action that this round-trip flowing generates disappears
The energy of air-flow has been supported, also can achieve the effect for reducing noise.
Embodiment 2
Air-conditioning internal machine wind deflector as described above, the present embodiment are different from place and are, the noise reduction in the present embodiment
The extending direction in hole 11 is parallel with the width direction of wind deflector ontology 1.
Noise reduction hole 11 is uniform columnar hole, and the shape of both ends open is identical, and its both ends open is formed by geometry
Line between the central point of figure is the axis in noise reduction hole 11, the direction where axis, the as extending direction in noise reduction hole 11.
As shown in connection with fig. 4, one of opening in noise reduction hole 11 is located in rear narrow side 13, another is located at the connection with cavity 12
Place, the extending direction in noise reduction hole 11 is parallel with the width direction of wind deflector ontology 1, so that noise reduction hole 11 is perpendicular to wind deflector ontology
1 length direction setting.
In this way, increasing into the throughput in cavity 12, wind noise is largely reduced out, so that air-conditioning internal machine
The noise reduction effect of wind deflector is more preferably.
Air-conditioning internal machine wind deflector at work, blows to the air flow direction in 1 rear narrow side 13 of wind deflector ontology and noise reduction hole
11 axial less parallel so that blow to air-flow in 1 rear narrow side 13 of wind deflector ontology it is most of by noise reduction hole 11 directly into
Enter into cavity 12, mutually liquidates with the gas generation in cavity 12, cut down the sound energy of air-flow.

In the inlet of cavity 12 mutual offset can occur for two strands of air-flows that noise reduction hole 11 enters, while also send out with the gas in cavity 12
Life mutually liquidates, and has further cut down the sound energy of air-flow；When air conditioner indoor unit opens left and right swing flap mode, (indoor unit is to the left
Swing flap is the left direction swing flap into Fig. 5, and swing flap is the right direction swing flap into Fig. 5 to the right), the gas that left direction scans out
It is most of to be entered in cavity 12 by the inclined noise reduction hole 11 in lower section to the left after stream is blown in 1 rear narrow side 13 of wind deflector ontology, to
It is most of by inclined noise reduction hole 11 to the right after the air-flow that right direction scans out is blown in 1 rear narrow side 13 of wind deflector ontology
Into in cavity 12, mutually liquidates with the gas generation in cavity 12, significantly cut down left and right swing flap mode downstream
Sound energy.
Optionally, as shown in connection with fig. 6, in the rear narrow side 13 of the left-half of 1 length direction of wind deflector ontology, noise reduction
Hole 11 is obliquely installed towards lower left (or lower right), and in the rear narrow side 13 of right half part, noise reduction hole 11 is towards right
Lower section (or lower left) is obliquely installed, with the noise reduction effect of many-sided, multi-angle raising air-conditioning.
