Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0033] Figures 1 to 8 The preferred embodiments and variant embodiments of the windshield of the present invention are shown, and there are multiple improvements in these embodiments; in the specific description, each improvement is described as an embodiment, and the technical features of the following embodiments can be freely combined without structural interference and conflict. When the combination of technical solutions is contradictory or cannot be realized, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope of the present invention.

[0034] The present invention provides a wind shield, and an indoor unit of an air conditioner (such as Figure 1 and Figure 8 ), and an air conditioner including the air conditioner indoor unit. The air conditioner can be a wall mounted unit or a cabinet unit, and the following content will specifically take the wall mounted unit as an example for detailed description. In addition, the wind shield is installed at the air duct of the indoor unit of the air conditioner, and can be installed at the air outlet or in the air duct (inside the air outlet).

[0035] In the embodiment of the present invention, Figures 1 to 3 As shown, the windshield 10 includes a board body 11 and a plurality of louvers 12, wherein the board body 11 extends in the left-right direction, and the board body 11 includes a left board body (not shown in the figure) and a right board body (not shown in the figure) connected to each other. The plurality of louvers 12 are arranged in the left-right direction on the board body 11, and the plurality of louvers 12 include a plurality of first louvers 12a installed on the left board body, and a plurality of second louvers 12b installed on the right board body.

[0036] The first louvers 12a are all inclined toward the left, and the second louvers 12b are all inclined toward the right. An opening 110 is provided on the plate body 11 on the left side of each of the first louvers 12a and on the plate body 11 on the right side of each of the second louvers 12b.

[0037] Specifically, before the louvers 12 are installed, when the airflow is blown out from the opening 110, the airflow is not guided and blown out directly from the opening 110, and its airflow direction does not change. After the louvers 12 are installed, the airflow can be blown out along the extension direction of the louvers 12.

[0038] When the indoor unit of the air conditioner equipped with the wind shield 10 is working, after the airflow blows toward the opening 110, it can flow in opposite directions along the first louver 12a and the second louver 12b, so that the blown airflow will not blow directly to the user. In addition, since the above-mentioned airflow flows in opposite directions, under the action of fluid pressure, the air near the middle of the outer side of the wind shield 10 will enter between the first louver 12a and the second louver 12b in the middle of the wind shield 10, and then flow toward both sides of the wind shield 10, and merge with the cold airflow blown out from the opening 110, thereby increasing the air output. Furthermore, since the cold airflow merges with the indoor air, the temperature of the airflow finally blown out by the air conditioner is relatively mild, not too cold, and the user experience is excellent.

[0039] The technical solution of the present invention is to set multiple openings 110 on the plate body 11 and install multiple louvers 12. By tilting the louvers 12 in opposite directions, the airflow blown out from the multiple openings 110 can flow in opposite directions, so that the blown airflow will not blow directly on the user.

[0040] When the crossflow impeller is running, the left and right side walls of the air duct of the hanging machine have a lagging force on the airflow, so the airflow in the middle of the air outlet is larger and smaller on both sides. Figure 2 and Figure 3 In order to reduce the wind resistance in the middle of the wind shield 10, in this embodiment, the opening between two adjacent louvers 12 gradually increases from both ends to the middle. Therefore, when the airflow blown out from the middle flows to both sides, it can drive the airflow on both sides of the air duct to blow out from the opening 110 (after the airflow blows out from the middle opening 110, it blows out to both sides. Since the airflow flowing out of the middle opening 110 has a faster flow rate, the fluid pressure at both ends of the front side of the wind shield 10 is relatively low. Under the effect of the pressure difference, the airflow on the rear side of the wind shield 10 will flow out to the front side). The opening between two adjacent wind shields 10 can be reduced by 5% to 10% from the middle to both sides.

[0041] Continue to refer to Figure 2 and Figure 3 Different from the above embodiment, in this embodiment, the inclination angle of the louver 12 gradually decreases from both ends to the middle. For example, the inclination angle of the louver 12 decreases by 5° to 10° from both sides of the plate body 11 to the middle.

[0042] Reference Figure 3 In the above embodiment, the first louver 12a and / or the second louver 12b can be arranged to extend in a straight line and be inclined. Figure 2, the first louver 12a and / or the second louver 12b can also be arranged to extend in an arc. For the louver 12 extending in a straight line, the airflow velocity derived therefrom is relatively rapid, the wind loss is relatively serious, and the noise is relatively large. For the louver 12 extending in an arc, when the airflow flows from the opening 110 to the louver 12, it can flow along the arc of the louver 12, the airflow velocity is relatively slow, the wind loss is small, the noise is small, and the back-blowing effect is also better. Of course, in order to prevent the airflow velocity blown out from the opening 110 from being too rapid, the louver 12 can also be arranged in a wavy shape, so that the flow path of the airflow on the louver 12 is lengthened, and the airflow velocity derived from the louver 12 is more moderate.

[0043] In the above embodiment, continue to refer to Figure 2 and Figure 3 , the inclination angle of the louver 12 cannot be too large or too small. If the inclination angle of the louver 12 is too large (the inclination angle refers to the angle formed by the louver tilting or bending toward one side from the position when it is perpendicular to the plate body; for curved louvers, the inclination angle refers to the angle between the tangent at the end of the louver and the louver when it is perpendicular to the plate body), for example, the inclination angle is greater than 60°, then the airflow derived from the louver 12 will mainly gather near the plate body 11, and the airflow will mainly circulate around the indoor unit of the air conditioner, which seriously affects the cooling efficiency, and will also form vortices due to the limited space at the air outlet, resulting in high noise. Of course, the inclination angle cannot be too small, for example, the inclination angle is less than 10°, so the airflow back-blowing effect is poor, and the windless effect is greatly reduced. In view of this, in this embodiment, the inclination angles of the first louver 12a and the second louver 12b in the left and right directions are 10° to 60°.

[0044] The indoor unit of the air conditioner has multiple air supply modes. When the crossflow impeller rotates faster, the airflow blows to the louver 12 and is blocked by the wind deflector 10. The air pressure in the air duct is high and the airflow is difficult to be delivered. In this way, on the one hand, the heat exchanger in the indoor unit will frost quickly, seriously affecting the cooling efficiency. On the other hand, the vortex in the air duct is serious and the noise is loud, affecting the user experience. In view of this, in this embodiment, reference is made to Figure 4 The material of the louver 12 is an elastic material. Thus, when the high-pressure airflow blows toward the louver 12, the louver 12 can be elastically deformed, thereby increasing the opening between two adjacent louvers 12, thereby achieving the purpose of pressure relief.

[0045] In addition, in order to make the pressure relief effect of the shutter 12 better, in this embodiment, Figure 5, the louver 12 is flexibly connected to the plate body 11 (the thickness of the connection L between the louver 12 and the plate body 11 is less than the thickness of the louver 12 itself). In this way, once the louver 12 is subjected to a large airflow thrust, the louver 12 can rotate relative to the plate body 11, thereby expanding the opening. Of course, if the louver 12 is flexibly connected to the plate body 11 and the material of the louver 12 itself is an elastic material, then its pressure relief effect will be better.

[0046] Reference Figure 6 In order to make the wind shield 10 have a better windless effect, in another preferred embodiment, the louver 12 is provided with a wind dispersion hole 120. In this way, on the one hand, the louver 12 is convenient for relieving the pressure of the airflow in the air duct, and on the other hand, the airflow guided by the wind shield 10 is more dispersed, and the windless effect is better.

[0047] Reference Figure 7 , since the first louver 12a is tilted to the left and the second louver 12b is tilted to the right, when the airflow is back-blown, the air near the middle of the outer side of the wind shield 10 will enter between the first louver 12a and the second louver 12b in the middle of the wind shield 10, thereby causing condensation water to be generated on the first louver 12a and the second louver 12b in the middle of the wind shield 10. In view of this, in this embodiment, a ventilation hole 111 is provided on the plate body 11 corresponding to the first louver 12a on the far right and the second louver 12b on the far left.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
