In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0031] In this application, the word “exemplary” is used to mean “serving as an example, instance, or illustration.” Any embodiment described in this application as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0032] The embodiment of the present application provides an air guide plate 100 and an air conditioner. Figures 8 to 11 As shown, the air conditioner includes a casing 200 and an air guide plate 100. The casing 200 is provided with an air outlet 201. The casing 200 is provided with an air duct 202 connected to the air outlet 201. The air duct 202 is provided with a fan 300. The air guide plate 100 is arranged at the air outlet 201. The air guide plate 100 extends along the length direction of the air outlet 201 and can rotate around the length direction of the air outlet 201.

[0033] like Figures 1 to 7As shown, the wind guide plate 100 includes an wind guide plate body 110 and a soft wind plate body 120. The wind guide plate body 110 is provided with an air outlet hole 111; the soft wind plate body 120 is provided with soft wind holes, which include a first soft wind hole 121, and the inner wall of the first soft wind hole 121 is inclined relative to the thickness direction of the soft wind plate body 120; the soft wind plate body 120 is connected to the wind guide plate body 110, and an air cavity is enclosed between the soft wind plate body 120 and the wind guide plate body 110, and the periphery of the air cavity at least partially forms an air outlet gap 101.

[0034] The air deflector body 110 has an outer surface and an inner surface. The outer surface of the air deflector body 110 refers to the side of the air deflector body 110 facing the outside of the housing 200 when the air conditioner is in soft wind mode. The inner surface of the air deflector body 110 refers to the side of the air deflector body 110 facing the inside of the housing 200 when the air conditioner is in soft wind mode. The inner surface of the air deflector body 110 can guide the airflow out of the air conditioner. The soft wind plate body 120 also has an inner surface and an outer surface. The outer surface of the soft wind plate body 120 refers to the side of the soft wind plate body 120 facing away from the air deflector body 110. The inner surface of the soft wind plate body 120 refers to the side of the soft wind plate body 120 facing the air deflector body 110. The inner surface of the soft wind plate body 120 can guide the airflow out of the air conditioner.

[0035] The air guide plate 100 and air conditioner provided in the embodiment of the present application, when the air guide plate 100 is in the soft wind position, the air flow out of the air conditioner will first impact the inner surface of the air guide plate body 110 and flow to the two sides of the air guide plate body 110 and the air outlet holes 111 respectively, and then the air flow in the air outlet holes 111 continues to impact the inner surface of the soft wind plate body 120 and flow to the air outlet gap 101 and the soft wind holes respectively. In the process of the air flow impacting the air guide plate body 110 and the soft wind plate body 120 respectively, the wind speed and wind pressure of the air flow can be effectively reduced to avoid causing discomfort to the human body; and when the air flow flows out from the first soft wind hole 121, it will be inclined relative to the thickness direction of the soft wind plate body 120, so that the air flow out is more dispersed and the wind speed is softer. At the same time, it can also interfere with several adjacent air flows to increase the turbulence intensity of the air flow out, so that the air flow out can more easily draw in the surrounding air for heat exchange, increase the thickness of the mixed air layer, and make the heat exchange more uniform, thereby improving the cooling and heating effects of the air conditioner.

[0036] Specifically, when the air conditioner is running in soft wind mode, the air guide plate body 110 rotates to the soft wind position so that the inner surface of the air guide plate body 110 faces the air outlet air flow of the air conditioner. The air outlet air flow coming out of the air outlet 201 of the air conditioner first hits the inner surface of the air guide plate body 110, and flows to the two sides of the air guide plate body 110 and the air outlet holes 111 respectively. Then the airflow in the air outlet holes 111 continues to hit the soft wind plate body 120, and flows to the air outlet gap 101 and the soft wind holes respectively. After passing through the first soft wind hole 121, the airflow is further broken up to realize dispersed soft wind, which can effectively reduce the wind speed and wind pressure of the air outlet airflow, and avoid causing discomfort to the human body.

[0037] In some embodiments of the present application, a plurality of first soft wind holes 121 are provided on the soft wind plate body 120, at least one first soft wind hole 121 is set as a first hole 1211, and at least one first soft wind hole 121 is set as a second hole 1212. The inclination direction of the inner wall of the first hole 1211 relative to the soft wind plate body 120 is different from the inclination direction of the inner wall of the second hole 1212 relative to the soft wind plate body 120, thereby achieving staggered soft wind and improving user comfort.

[0038] Specifically, when the outlet airflow hits the inner surface of the air guide plate body 110, the outlet airflow will flow out from both sides of the air guide plate body 110 and the air outlet holes 111, forming multiple airflows in different directions, among which the airflows on both sides of the air guide plate body 110 are stronger and the wind speed is larger; the airflow in the air outlet holes 111 continues to hit the inner surface of the soft wind plate body 120 and then flows out from the air outlet gap 101 and the soft wind holes. Since the multiple first soft wind holes 121 have different inclination directions, the airflow again forms multiple airflows in different directions. The multiple airflows in different directions impact and interfere with each other, thereby further reducing the flow rate and wind pressure of the outlet airflow, effectively enhancing the turbulence intensity of the outlet airflow, and realizing staggered soft wind.

[0039] Optionally, the soft wind plate body 120 has a first side 123 and a second side 124 relative to each other, the inner wall of the first hole 1211 is inclined toward the first side 123 relative to the thickness direction of the soft wind plate body 120, and the inner wall of the second hole 1212 is inclined toward the second side 124 relative to the thickness direction of the soft wind plate body 120, thereby achieving that the inclination direction of the inner wall of the first hole 1211 relative to the soft wind plate body 120 is different from the inclination direction of the inner wall of the second hole 1212 relative to the soft wind plate body 120.

[0040] For example, combined Figures 2 to 4 and Figure 6As shown, the first hole 1211 is arranged close to the first side 123 and the second hole 1212 is arranged close to the second side 124. The inner wall of the first hole 1211 is inclined toward the first side 123 relative to the thickness direction of the soft wind plate body 120, and the inner wall of the second hole 1212 is inclined toward the second side 124 relative to the thickness direction of the soft wind plate body 120, that is, the inner wall of the first hole 1211 and the inner wall of the second hole 1212 are arranged opposite to each other (as shown in FIG. Figure 6 Alternatively, the first hole 1211 is arranged close to the second side 124 and the second hole 1212 is arranged close to the first side 123, the inner wall of the first hole 1211 is inclined toward the first side 123 relative to the thickness direction of the soft wind plate body 120, and the inner wall of the second hole 1212 is inclined toward the second side 124 relative to the thickness direction of the soft wind plate body 120, that is, the inner wall of the first hole 1211 and the inner wall of the second hole 1212 are arranged opposite to each other (as shown in FIG. Figure 7 shown).

[0041] In some embodiments of the present application, the soft wind hole further includes a second soft wind hole 122, and the inner wall of the second soft wind hole 122 is arranged parallel to the thickness direction of the soft wind plate 120. By providing the second soft wind hole 122, a staggered soft wind effect can be achieved, thereby improving user comfort.

[0042] Specifically, after the outlet airflow hits the inner surface of the air guide plate body 110, the outlet airflow will flow out from both sides of the air guide plate body 110 and the air outlet holes 111, forming multiple airflows in different directions, among which the airflows on both sides of the air guide plate body 110 are stronger and the wind speed is larger; the airflow in the air outlet holes 111 continues to hit the inner surface of the soft wind plate body 120 and then flows out from the air outlet gap 101 and the soft wind holes. Since the inner wall of the first soft wind hole 121 is inclined relative to the thickness direction of the soft wind plate body 120, and the inner wall of the second air outlet hole 111 is parallel to the thickness direction of the soft wind plate body 120, the airflow again forms multiple airflows in different directions. The multiple airflows in different directions impact and interfere with each other, thereby further reducing the flow rate and wind pressure of the outlet airflow, effectively enhancing the turbulence intensity of the outlet airflow, and realizing staggered soft wind.

[0043] Optionally, two groups of first soft wind holes 121 are arranged at intervals on the soft wind plate body 120, each group of first soft wind holes 121 is composed of one or more first soft wind holes 121, and the inclination directions of the inner walls of the two groups of first soft wind holes 121 relative to the soft wind plate body 120 are different; at least one group of second soft wind holes 122 is arranged between the two groups of first soft wind holes 121, and each group of second soft wind holes 122 is composed of one or more second soft wind holes 122.

[0044] For example, Figures 1 to 5As shown, the soft wind plate body 120 is provided with two groups of first soft wind holes 121 arranged at intervals along the width direction of the soft wind plate body 120, and each group of first soft wind holes 121 is composed of multiple first soft wind holes 121. For the convenience of description, one group of first soft wind holes 121 is defined as first holes 1211, and the other group of first soft wind holes 121 is defined as second holes 1212. The multiple first holes 1211 are arranged in a row along the length direction of the soft wind plate body 120, and the multiple second holes 1212 are arranged in a row along the length direction of the soft wind plate body 120; a group of second soft wind holes 122 is arranged between the two groups of first soft wind holes 121, and each group of second soft wind holes 122 is composed of multiple second soft wind holes 122, and the multiple second soft wind holes 122 are arranged in a row along the length direction of the soft wind plate body 120.

[0045] Optionally, the air deflector body 110 is provided with one or more air outlet holes 111, and the soft air body is provided with multiple soft air holes, with each air outlet hole 111 corresponding to multiple soft air holes. In other words, one air outlet hole 111 can be provided on the air deflector body 110, and one air outlet hole 111 can correspond to multiple soft air holes; or, multiple air outlet holes 111 can be provided on the air deflector body 110, and each air outlet hole 111 can correspond to multiple soft air holes.

[0046] In some embodiments of the present application, the soft air plate 120 is provided with a plurality of soft air holes, at least two of which are of different shapes and / or sizes. Optionally, the shape of the soft air hole can be circular, oval, round, elongated, square, triangular, or other geometric shapes.

[0047] For example, Figure 2 and Figure 4 As shown, the shapes of the multiple first holes 1211 in the first soft air hole 121 include oval and circular shapes, and the shapes of the multiple second holes 1212 include oval and circular shapes; the shapes of the multiple second soft air holes 122 are all oval, and the sizes of some second soft air holes 122 are different from the sizes of the oval first soft air holes 121.

[0048] Specifically, the air deflector body 110 is rotatably connected to the housing 200. The soft air plate body 120 should be within the radius of a circle drawn with the rotation center of the air deflector body 110 as the center, with the distance between the rotation center of the air deflector body 110 and the outermost side edge of the air deflector body 110 as the radius. This can prevent the soft air plate body 120 from colliding with the air conditioner housing 200 or other components during the rotation of the air deflector body 110. Specifically, both ends of the air deflector body 110 can be rotatably connected to the housing 200 via a rotating shaft structure, and the rotation axis of the air deflector body 110 is set in the middle of the air deflector body 110.

[0049] In some embodiments of the present application, the air deflector 100 has an initial position, a soft wind position, an upper wind guide position, and a lower wind guide position during rotation. That is, the air deflector body 110 can switch between the initial position, the soft wind position, the upper wind guide position, and the lower wind guide position. Accordingly, the air conditioner has a soft wind mode, an upper wind guide mode, a lower wind guide mode, and a normal air flow mode. These four modes are described in detail below with reference to the accompanying drawings:

[0050] like Figure 8 As shown, the air conditioner is configured as follows: in the soft wind mode, the air guide plate 100 rotates to the soft wind position, at which time the inner surface of the air guide plate 100 faces the air flow of the air conditioner, so that part of the air flow passes through the air outlet gap 101 and the soft wind hole of the air guide plate 100 and is blown out.

[0051] like Figure 9 As shown, the air conditioner is configured as follows: in the upper air guide mode, the air guide plate 100 rotates to the upper air guide position, and the inner surface of the air guide plate body 110 faces upward to make the air flow blow upward (i.e., upward air guide).

[0052] like Figure 10 As shown, the air conditioner is configured as follows: in the downward wind guide mode, the wind guide plate 100 rotates to the downward wind guide position, and the inner surface of the wind guide plate body 110 faces rearward and downward to allow the outlet air flow to blow downward (i.e., downward wind guide).

[0053] like Figure 11 As shown, the air conditioner is configured as follows: in normal air outlet mode, the air guide plate 100 rotates to the initial position, at which time the inner surface of the air guide plate body 110 faces downward so that the air flow is blown forward. In this mode, the resistance encountered by the air flow is minimal (i.e., the wind resistance is minimal).

[0054] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0055] The above is a detailed introduction to the air guide plate and air conditioner provided in the embodiments of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
