In an embodiment of the present invention, as shown in fig. 1 and 2, the wind deflector 20 includes a plate body 100 and a plurality of wind-shielding blades 200, wherein a plurality of mounting holes are formed through the plate body 100, a plurality of wind-shielding blades 200 extending from inner walls of the mounting holes toward centers of the mounting holes are disposed in each of the mounting holes, one end of each wind-shielding blade 200 is connected to a hole wall of the mounting hole, and the other end of each wind-shielding blade 200 is connected to the other end of the wind-shielding blade; the plurality of wind-shielding blades 200 are arranged along a circular track in a deflection way, and the wind-shielding blades 200 are inclined towards the same hole surface of the mounting hole in the same direction.
Specifically, the principle of achieving the non-wind feeling in the patent is that firstly, since the plurality of wind-shielding blades 200 are inclined towards the same hole surface of the mounting hole in the same direction, and the wind-dispersing gap 300 is formed between two adjacent wind-shielding blades 200, compared with the wind-dispersing hole vertically penetrating through the plate body 100, when the gas passes through the obliquely arranged wind-dispersing gap 300, the gas flowing distance is longer, the kinetic energy loss is more, and the non-wind feeling effect is better; secondly, the plurality of wind-shielding blades 200 are arranged along a circular track in a deflection manner, and the gas flowing out of the deflected wind-dispersing gap 300 changes the gas flow direction, so that the strength of the airflow blown out of the front face of the wind-shielding plate 20 is weakened, and the non-wind-feeling effect of the air-out airflow is improved; finally, the gas that flows out through a plurality of wind gaps 300 that looses can form rotatory air current, and the interaction between a plurality of rotatory air currents is broken up each other, and consequently, when the air current blows to the human body through the deep bead 20 that this patent provided, air current intensity weakens, and the air current comfort level is higher, can avoid the user to suffer from the air conditioner disease.
More importantly, the wind deflector 20 provided by the patent reduces the strength of the air flow mainly through the interaction between the rotating air flows, and realizes no wind feeling, so that the opening rate of the wind deflector 20 is not required to be reduced while the no wind feeling of the outlet air flow of the indoor unit of the air conditioner is improved, namely, the wind shielding area of the wind deflector 20 is not required to be increased (the wind shielding area is the difference between the area of the wind deflector 20 and the area of the air dispersing gap 300), therefore, the wind deflector 20 provided by the patent can avoid a large amount of loss of the supplied air flow, and the air supply effect of the indoor unit of the air conditioner can be improved.
The structure of the wind deflector 20 of this patent will now be described in detail with reference to figures 3 and 4. The shape of the wind deflector 20 is matched with the shape of the air outlet, and for the wall-mounted air conditioner, the air outlet is mostly in a strip shape, so the wind deflector 20 in the embodiment is in a strip shape. The wind-shielding blades 200 are arranged at intervals along the length direction of the wind-shielding plate 20, each group of wind-shielding blades 200 comprises a plurality of wind-shielding blades 200 distributed in a radiation state along the circumferential direction, the inner ends of the length directions of the wind-shielding blades 200 are arranged near the circle center of a circle, and the outer ends of the length directions of the wind-shielding blades 200 are arranged near the circumference of the circle.
Referring to fig. 1, in order to increase the area of the fixed connection of the wind-shielding blades 200 and further improve the bonding strength between the wind-shielding blades 200, considering that the inner ends of the wind-shielding blades 200 are fixed together, the wind-shielding plate 20 further includes a connecting portion 400 disposed in the middle of the mounting hole, and the inner ends of the wind-shielding blades 200 are all fixedly connected to the connecting portion 400. Specifically, the connecting portion 400 is circular, and a plurality of the inner end interval of the wind-shielding blade 200 is fixed in the circumferential side wall of the connecting portion 400, and because the area of the circumferential side wall of the connecting portion 400 is much larger than the area of the inner end of the wind-shielding blade 200, the structural strength of the inner ends of the wind-shielding blades 200 respectively fixed with the connecting portion 400 is larger than the structural strength of the inner end mutual fixed connection of the wind-shielding blades 200.
As a preferable mode, as shown in fig. 2, the connection part 400 is arranged in a circular shape, and the center of the connection part 400 is provided with a through hole, since the distance between the plurality of wind-shielding blades 200 near the inner ends thereof is small, the area of the formed wind-scattering gap is small, and the amount of the air flow passing through is small, the through hole is arranged at the center of the connection part 400 in the present invention, which can make up the above-mentioned defect, and after the through hole is arranged, the middle parts of the plurality of wind-shielding blades 200 can be supplied with air to circulate, so that the air flowing out through the wind-shielding plates 20.
Now, the structure of the wind-shielding blade 200 of this patent will be described in detail with reference to fig. 1, in order to improve the structural strength of the wind-shielding blade 200, the wind-shielding blade 200 is configured as an arc-shaped blade protruding outwards in the clockwise direction or the counterclockwise direction, and since the material usage amount of the arc-shaped blade is more than that of the blade having a planar structure, the structural strength of the wind-shielding blade 200 can be improved, and the service life of the wind-shielding blade 200 can be further prolonged.
Further, the thickness of the wind-shielding blade 200 is far away from the direction of the center of the mounting hole and is arranged in an increasing mode, so that the area of the wind-shielding blade 200 fixedly connected with the inner hole wall of the mounting hole is larger, the connection strength between the wind-shielding blade 200 and the wind shield 20 can be improved, and the service life of the wind-shielding blade 200 is further prolonged.
With continued reference to fig. 1 and 2, considering that the wind-shielding blades 200 are inclined at a certain angle to enable the airflow flowing out from the adjacent wind-shielding blades 200 to rotate, and the different rotating airflows collide with each other to completely break up the airflow, in an embodiment of the present invention, the range of the axial included angle between the wind-shielding blade 200 and the mounting hole is 0 to 60 degrees, since the wind-shielding blades 200 have an angle with the axial direction of the mounting hole, i.e., the inflow direction of the gas, the deflection of the gas flow is enabled, when the inclination angle of the wind-shielding blades 200 is 0 to 60, the deflection degree of the air flow is moderate after the air flows through the wind-dispersing gap 300 between the wind-shielding blades 200, therefore, the air flows flowing out of different air dispersing gaps 300 can be fully collided, the air mixing effect is improved, and the no-wind feeling of the air outlet flow of the indoor unit 10 of the air conditioner is finally realized.
It should be noted that the no wind feeling means that the strength of the outlet airflow is moderate, so that a user can feel comfortable; 0 ° to 60 ° is the maximum range of the inclination angle of the wind-shielding blade 200 when the air currents flowing out through the plurality of wind-dispersing gaps 300 can have good interaction, and in another embodiment of the present patent, the range of the inclination angle of the wind-shielding blade 200 is preferably 0 ° to 45 °, and if and only if the angle between the wind-shielding blade 200 and the axial direction of the installation hole is 20 °, the non-wind feeling effect is the best.
As a preferable mode, the thickness of the wind-shielding blade 200 is gradually decreased from the middle of the thickness direction of the plate body 100 to both sides of the thickness direction, specifically, the wind-shielding plate 20 has an air inlet surface and an air outlet surface which are oppositely arranged, and since the thickness of the contact position of the wind-shielding blade 200 and the air inlet surface and the air outlet surface is smaller than the thickness of other positions, the connection position of the wind-shielding blade 200 and the air inlet surface and the air outlet surface can form a flared opening, thereby reducing the noise when the air flows into and out of the wind-dispersing gap 300.
Referring to fig. 3 and 4, in order to further increase the amount of air supplied by the indoor unit 10 of the air conditioner, a plurality of air dispersing holes 500 are further formed through the plate body 100 around the air dispersing gap 300, and the air dispersing holes 500 may be configured in a circular shape, a strip shape, an oval shape, or the like, and the circular air dispersing holes 500 are convenient for processing and forming, so in this embodiment, the air dispersing holes 500 are arranged in a circular shape. Since the present embodiment is provided with the plurality of air-dispersing gaps 300 and the plurality of circular air-dispersing holes 500, the present invention can increase the amount of air supplied to the indoor air-conditioning unit 10 and improve the air-supplying effect of the indoor air-conditioning unit 10 while achieving no wind sensation.
In addition, since the air flow flowing out through the air dispersing gap 300 can interact with the air flow flowing out through the air dispersing holes 500, the air flows can be mixed, and a better non-wind effect can be realized.
In order to change the air outlet direction of the air outlet flow, the air dispersing holes 500 extend obliquely (not shown) along the thickness direction of the plate body 100, so that the air flow direction is changed, and the strength of the air flow blown out from the front surface of the wind deflector 20 is weakened; preferably, the inclined direction of the air dispersing hole 500 intersects with the inclined direction of the air dispersing gap 300, so that the air flow flowing out through the air dispersing gap 300 can intersect with the air flow flowing out through the air dispersing hole 500, thereby dispersing the air flow to form a dispersed flow, and further improving the no-wind effect of the air flow from the indoor unit 10 of the air conditioner.
However, the design of the present invention is not limited to this, in other embodiments, the air dispersing holes 500 may also be disposed in an inclined manner toward other directions, for example, toward the outer side of the width direction of the wind shielding plate 20, so as to enlarge the radiation area of the outlet airflow, and further improve the temperature adjusting effect of the indoor air conditioner 10.
As shown in fig. 3, the present invention further provides an air-conditioning indoor unit 10, where the air-conditioning indoor unit 10 includes an air-conditioning indoor unit main body and a wind deflector 20, the air-conditioning indoor unit main body is provided with an air outlet, and the wind deflector 20 is rotatably installed at the air outlet; the specific structure of the wind deflector 20 refers to the above embodiments, and since the air-conditioning indoor unit 10 provided by the present invention adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
