[0054] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0055] Reference below Figures 1-19 The wind guide assembly 1 according to an embodiment of the present invention is described.

[0056] Reference Figure 2 、 Figure 3 and Figure 18According to the first embodiment of the present invention, the wind guide assembly 1 includes a first wind guide component 11 and a second wind guide component 13. The first wind guide component 11 includes a wind guide frame 111 and a plurality of guide blades 115. The wind guide frame 111 is rotatable and the rotation axis of the wind guide frame 111 extends along a first direction. The plurality of guide blades 115 are provided on the wind guide frame 111 and the plurality of guide blades 115 extend along the first direction (for example, see Figure 1 The guide blades 115 are arranged at intervals (in the e1 direction in the figure), each guide blade 115 is fixed relative to the air guide frame 111, and at least some of the guide blades 115 are tilted relative to the reference plane, and the reference plane is perpendicular to the first direction. A plurality of guide blades 115 are provided on the air guide frame 111, and the air guide frame 111 can provide support and fixation for the guide blades 115. The guide blades 115 can regulate and guide the airflow of the air outlet 22, and by driving the air guide frame 111 to rotate, the guide direction of the airflow of the guide blades 115 can be adjusted. There is no need to move each guide blade 115 relative to the air guide frame 111 to adjust the guide direction. The guide direction adjustment method of the guide blades 115 is relatively simple and convenient for processing and manufacturing.

[0057] The second air guide component 13 includes a connecting rod 131 and a plurality of louvers 132 arranged along a first direction. The connecting rod 131 extends along the first direction. Each louver 132 is connected to the connecting rod 131. The connecting rod 131 can move along the first direction to drive the louver 132 to swing in the first direction. The louver 132 is formed with a avoidance opening 133 for avoiding the first air guide component 11. The avoidance opening 133 can facilitate the accommodation of the first air guide component 11 therein, thereby making the assembly between the first air guide component 11 and the louver 132 more convenient and reducing or avoiding the possibility of interference between the louver 132 and the first air guide component 11. By driving the connecting rod 131 to move along the first direction, the amplitude of rotation of the louver 132 can be adjusted, thereby further adjusting the direction and amount of airflow flowing through the air guide assembly 1.

[0058] By driving the air guide frame 111 to rotate to adjust the guide direction of the airflow by the guide blade 115, and driving the louver 132 to rotate along the first direction through the connecting rod 131 to adjust the direction of the airflow, the multi-directional movement combination of the guide blade 115 and the louver 132 can realize the diversification of the air outlet mode, improve the user experience, and make the air outlet mode more flexible to meet the different needs of users.

[0059] For example, the air guide assembly 1 is used in an air conditioner and is disposed in the air outlet duct 23 of the air conditioner. The air guide assembly 1 can guide the airflow in the air outlet duct 23, allowing the airflow to flow more smoothly to the air outlet 22, reducing losses during the flow of the airflow, and facilitating increased airflow. The air guide assembly 1 includes an air guide frame 111 and guide vanes 115. By driving the air guide frame 111 to rotate, the guide vanes 115 can adjust the direction of the airflow in the first direction to achieve air supply to different areas of the room. Furthermore, by driving the connecting rod 131, the louvers 132 can be driven to swing in the first direction to adjust the direction of the airflow in the first direction. By combining the guide vanes 115 and the louvers 132, the air outlet mode can be diversified and made more flexible.

[0060] Taking the first direction as the up-down direction as an example, the air guide assembly 1 of the embodiment of the present utility model is described.

[0061] For example, by rotating the air guide frame 111 so that the airflow guided by the guide blades 115 is directed to blow downward, and by driving the louver 132 to swing downward through the connecting rod 131, the guide blades 115 and the louver 132 jointly guide the airflow to flow downward, which can enhance the downward guiding effect of the airflow, so that the airflow is more concentrated in blowing downward. For example, when the air conditioner is in heating mode, the hot air is blown downward to enhance the effect of warming the feet with the hot air, thereby improving the user experience. Of course, it is also possible that the guide blades 115 guide the airflow to blow upward, and the louver 132 also guide the airflow to flow upward, which can enhance the upward guiding effect of the airflow, so that the airflow is more concentrated in blowing upward. For example, when the air conditioner is in cooling mode, the cold air is blown upward, which can utilize the principle of cold air throwing downward, thereby achieving rapid indoor cooling while reducing the discomfort caused by direct blowing.

[0062] For another example, by rotating the air guide frame 111 so that the airflow guided by the guide vanes 115 is directed upward, and by driving the louvers 132 to swing downward via the connecting rod 131 to guide the airflow downward, if the louvers 132 are located above the guide vanes 115, the airflow can be directed more concentratedly toward the space between the louvers 132 and the guide vanes 115, thereby achieving long-distance air supply. Of course, if the guide vanes 115 guide the airflow downward and the louvers 132 guide the airflow upward, if the guide vanes 115 are located above the louvers 132, the airflow can also be directed more concentratedly toward the space between the louvers 132 and the guide vanes 115, thereby achieving long-distance air supply.

[0063] For another example, by rotating the air guide frame 111 so that the airflow directed by the guide blades 115 is directed upward, and by driving the louvers 132 to swing downward via the connecting rod 131 to guide the airflow downward, if the guide blades 115 are located above the louvers 132, the guide blades 115 guide the airflow upward while the louvers 132 guide the airflow downward, thereby dispersing the airflow and reducing the discomfort caused by direct blowing. Of course, if the guide blades 115 guide the airflow downward and the louvers 132 guide the airflow upward, if the louvers 132 are located above the guide blades 115, the guide blades 115 guide the airflow downward while the louvers 132 guide the airflow upward, thereby dispersing the airflow and reducing the discomfort caused by direct blowing.

[0064] In the description of the present invention, “plurality” means two or more.

[0065] According to the embodiment of the utility model, the wind guide assembly 1 includes a first wind guide component 11 and a second wind guide component 13. The first wind guide component 11 and the second wind guide component 13 are combined. The first wind guide component 11 includes an air guide frame 111 and a plurality of guide blades 115 fixed to the air guide frame 111, and at least some of the guide blades 115 are inclined relative to a reference plane. The guide direction of the airflow by the guide blades 115 can be adjusted by rotating the air guide frame 111. The second wind guide component 13 includes a connecting rod 131 and a plurality of louvers 132 arranged along a first direction. The movement of the connecting rod 131 along the first direction can drive the louvers 132 to swing in the first direction. By adjusting the guide direction of the airflow by the guide blades 115 and the guide direction of the airflow by the louvers 132, for example, the guiding directions of the guide blades 115 and the louvers 132 can be made consistent to enhance the air guiding effect, or the guiding directions of the guide blades 115 and the louvers 132 can be made different to achieve diversified air outlet modes.

[0066] Reference Figure 1 According to some embodiments of the present invention, the air guide frame 111 and the connecting rod 131 are driven by different driving structures respectively, so that independent driving of the air guide frame 111 and the connecting rod 131 can be achieved. For example, the driving mechanism includes a first driving mechanism and a second driving mechanism. The first driving mechanism is connected to the air guide frame 111 to drive the air guide frame 111 to rotate, and the second driving mechanism is connected to the connecting rod 131 to drive the connecting rod 131 to move. By driving the air guide frame 111 by the first driving mechanism and driving the connecting rod 131 by the second driving mechanism, the guide blade 115 and the connecting rod 131 can be independently controlled.

[0067] For example, the air guide frame 111 can be driven solely by the first driving mechanism to adjust the airflow guiding direction of the guide blades 115; the connecting rod 131 can be driven solely by the second driving mechanism to drive the louver 132 to swing to adjust the airflow guiding direction of the louver 132; the air guide frame can also be driven by the first driving mechanism to adjust the airflow guiding direction of the guide blades 115, and the louver 132 can be driven to swing by the second driving mechanism via the connecting rod 131 to adjust the airflow guiding direction of the louver 132.

[0068] Reference Figure 2 、 Figure 7 and Figure 11 According to some embodiments of the present invention, the angle α between the guide vane 115 and the reference surface ranges from 25° to 60°. For example, the angle α between the guide vane 115 and the reference surface can be 25°, 35°, 45°, 55°, 60°, etc. By ensuring that the angle α between the guide vane 115 and the reference surface is not less than 25°, the airflow can be effectively guided so that the airflow is blown out toward the set angle. By ensuring that the angle α between the guide vane 115 and the reference surface is not greater than 60°, the area blocked by the guide vane 115 on the airflow can be minimized, thereby reducing airflow loss. This avoids increasing the area blocked by the guide vane 115 on the airflow due to an excessively large angle α between the guide vane 115 and the reference surface. Correspondingly, a larger airflow blocking area results in a larger airflow loss.

[0069] By setting the included angle α between the guide vane 115 and the reference surface to be in the range of 25° to 60°, the airflow can be effectively guided and the air volume loss can be reduced as much as possible.

[0070] Reference Figure 2 、 Figure 7 and Figure 11 According to some embodiments of the present invention, the angle α between the guide vane 115 and the reference surface ranges from 35° to 45°. For example, the angle α between the guide vane 115 and the reference surface can be 35°, 38°, 40°, 43°, 45°, etc. By ensuring that the angle α between the guide vane 115 and the reference surface is not less than 35°, the guiding effect of the guide vane 115 can be further enhanced. By ensuring that the angle α between the guide vane 115 and the reference surface is not greater than 45°, a small amount of air loss can be ensured, avoiding an increase in air flow resistance caused by an excessively large angle α between the guide vane 115 and the reference surface.

[0071] By setting the included angle α between the guide vane 115 and the reference surface to be in the range of 35° to 45°, the guiding effect of the guide vane 115 on the airflow and the wind resistance can be better balanced.

[0072] Reference Figure 4 、 Figure 5 and Figure 9 According to some embodiments of the present invention, the guide blade 115 is circular, and the edge profile of the guide blade 115 is arc-shaped, which can reduce the possibility of airflow separation, thereby reducing the wind resistance to reduce the air volume loss, which is conducive to increasing the air volume.

[0073] Reference Figure 9 、 Figure 13 and Figure 18 According to some embodiments of the present invention, the projection of the center of the guide vane 115 on the reference plane is a first projection, and the projection of the rotation axis of the air guide frame 111 on the reference plane is a second projection. The first projection and the second projection coincide with each other, or the distance between the first projection and the second projection is less than 5 mm. For example, the distance between the first projection and the second projection can be 0 mm, 1 mm, 2 mm, 3 mm, 5 mm, etc. By making the distance between the first projection and the second projection less than 5 mm, the center of the guide vane 115 can be as close as possible to the rotation axis of the air guide frame 111, so that the guide vane 115 and the air guide frame 111 rotate synchronously. This can reduce the possibility of torque imbalance caused by the center of the guide vane 115 deviating from the rotation axis of the air guide frame 111, which is conducive to enhancing the stability of the guide vane 115. A certain assembly error between the air guide frame 111 and the guide vane 115 is allowed, making the assembly of the guide vane 115 and the air guide frame 111 more convenient.

[0074] Reference Figure 6 、 Figure 7 and Figure 17 According to some embodiments of the present invention, the air guide frame 111 is provided with a plurality of guide blades 115. The plurality of guide blades 115 are arranged at intervals along the first direction, which can make the airflow regulated by the air guide assembly 1 more evenly distributed in the first direction. The plurality of guide blades 115 can also better adjust the direction of the airflow, thereby improving the airflow guidance effect of the air guide assembly 1. The air guide frame 111 is provided with a plurality of guide blades 115. By driving the air guide frame 111 to rotate, the plurality of guide blades 115 can be driven to rotate simultaneously, thereby improving the airflow regulation efficiency of the air guide assembly 1.

[0075] Reference Figure 3 、 Figure 12 and Figure 19 According to some embodiments of the present invention, the projection of the air guide frame 111 on the reference plane is located within the projection of the guide blade 115 on the reference plane, so that the airflow flowing through the air guide frame 111 can be further regulated by the guide blade 115 as much as possible, thereby enhancing the regulating effect of the air guide assembly 1 on the airflow in multiple directions.

[0076] Reference Figure 4 、 Figure 5 and Figure 17According to some embodiments of the present invention, the air guide frame 111 includes a plurality of air guide ribs 112 arranged in parallel and at intervals, each air guide rib 112 extending along a first direction, and the air guide ribs 112 are provided through a plurality of guide blades 115. The plurality of air guide ribs 112 can enhance the overall structural strength of the air guide assembly 1. The plurality of air guide ribs 112 arranged in parallel and at intervals can guide the airflow passing through the air guide assembly 1, so that the airflow passing through the air guide assembly 1 is directed in a second direction (for example, as can be seen in FIG. Figure 1 By having multiple air guide ribs 112 passing through multiple guide blades 115, the air flow can be guided in multiple directions.

[0077] Reference Figure 17 According to some embodiments of the present invention, the air guide frame 111 further includes two mounting plates 113, which are arranged on opposite sides of the air guide ribs 112 along the first direction and are connected to the air guide ribs 112. A rotating shaft 114 is provided on the mounting plates 113. The mounting plates 113 can support and fix the air guide ribs 112. By connecting the two mounting plates 113 to the air guide ribs 112, the overall structural strength of the air guide frame 111 can be enhanced, thereby reducing or avoiding the possibility of deformation or damage to the air guide frame 111 under the impact of airflow. By providing the rotating shaft 114 on the mounting plates 113, when the rotating shaft 114 rotates, the air guide ribs 112 can be driven to rotate via the mounting plates 113, and the guide vanes 115 can be driven to rotate at the same time, thereby achieving the air guide component 1's guiding effect on the airflow in multiple directions.

[0078] Reference Figure 18 According to some embodiments of the present invention, the guide blade 115 is circular, and the width of the guide rib 112 is greater than the radius R1 of the guide blade 115. The wider guide rib 112 can better guide the airflow, thereby enhancing the effect of guiding the airflow in the second direction. Furthermore, since the width of the guide rib 112 is greater than the radius R1 of the guide blade 115, the guide rib 112 can provide a stronger support force for the guide blade 115, thereby enhancing the stability of the guide blade 115 and helping to reduce or avoid shaking or vibration of the guide blade 115 caused by airflow impact.

[0079] Reference Figure 10 、 Figure 11 and Figure 14 According to some embodiments of the present invention, the first air guide component 11 is an integrally formed component, which can improve the overall structural strength of the first air guide component 11 and eliminate the assembly process between the air guide frame 111 and the multiple guide blades 115.

[0080] Reference Figure 3 、 Figure 18 and Figure 19 According to some embodiments of the present invention, the louver 132 is formed with a clearance opening 133 for avoiding the first air guide component 11. The clearance opening 133 can facilitate the first air guide component 11 to be accommodated therein, thereby facilitating the assembly between the first air guide component 11 and the louver 132 and reducing or avoiding the possibility of interference between the louver 132 and the first air guide component 11.

[0081] Optionally, the louver 132 may be half-open, with the avoidance opening 133 formed at least partially at the open end of the louver 132 ; the louver 132 may also be annular, with the avoidance opening 133 located in the middle of the louver 132 to avoid the first air guide component 11 .

[0082] Reference Figure 4 、 Figure 5 and Figure 19 According to some embodiments of the present invention, the projection of the avoidance opening 133 on the reference surface is the third projection, the projection of the first air guide component 11 on the reference surface is the fourth projection, and the overlapping area of ​​the fourth projection and the third projection is greater than 1 / 2 of the area of ​​the fourth projection. For example, the ratio of the overlapping area of ​​the fourth projection and the third projection to the area of ​​the fourth projection can be 2 / 3, 3 / 4, 4 / 5, 5 / 6, etc. By ensuring that the overlapping area of ​​the fourth projection and the third projection is greater than 1 / 2 of the area of ​​the fourth projection, the airflow can flow through the louver 132 and the first air guide component 11 as much as possible, thereby enhancing the guiding effect of the air guide assembly 1.

[0083] Reference Figure 3 、 Figure 6 and Figure 12 According to some embodiments of the present invention, the louvers 132 are partially located upstream of the first air guide component 11 in the direction of airflow. This location of the louvers 132 upstream of the first air guide component 11 can pre-regulate the airflow toward the first air guide component 11, facilitating more precise adjustment of airflow distribution. The louvers 132 and the first air guide component 11 work together to achieve multi-level adjustment in the direction of airflow, improving the airflow guidance effect of the air guide assembly 1.

[0084] Reference Figure 11 、 Figure 14 and Figure 17According to some embodiments of the present invention, the plurality of guide blades 115 are divided into a plurality of guide blade groups 116. The plurality of guide blade groups 116 are arranged at intervals along a first direction. Each guide blade group 116 includes one or more guide blades 115 arranged at intervals along the first direction. Louvers 132 are located between two adjacent guide blade groups 116. Louvers 132 are provided between two adjacent guide blade groups 116. The louvers 132 can initially regulate the airflow passing between the two adjacent guide blade groups 116, which is then further regulated by the guide blades 115 within the guide blade groups 116. The combination of the louvers 132 and the guide blade groups 116 can achieve diversified airflow patterns to meet the different needs of users.

[0085] Reference Figure 11 and Figure 14 According to some embodiments of the present invention, a louver 132 is provided between two adjacent groups of guide blades 116, which can better balance the guiding effect of the louver 132 on the airflow and the wind resistance. While the louver 132 and the guide blade group 116 work together to improve the guiding effect of the air guide component 1 on the airflow, the air volume loss can be reduced as much as possible, and the increase in the airflow blocking area due to an excessive number of louvers 132 can be reduced or avoided. Correspondingly, the smaller the airflow blocking area, the less wind resistance and the less air volume loss.

[0086] Reference Figure 17 According to some embodiments of the present invention, the spacing between two adjacent guide blades 115 in the same guide blade group 116 in the first direction is smaller than the spacing between two adjacent guide blade groups 116 in the first direction, so that the flow area of ​​the airflow between the two adjacent guide blade groups 116 can be sufficiently large, which can facilitate the joint action of the louver 132 and the guide blade group 116 to enhance the wind guiding effect or realize the diversification of the air outlet mode.

[0087] Reference Figure 17 According to some embodiments of the present invention, the number of guide blades 115 in each guide blade group 116 is 1 to 3. For example, the number of guide blades 115 in each guide blade group 116 can be 1, 2, or 3. By having at least one guide blade 115 in each guide blade group 116, the airflow passing through the guide blade group 116 can be effectively guided. By having no more than three guide blades 115 in each guide blade group 116, airflow loss can be minimized, reducing or avoiding an increase in the airflow blocking area due to an excessive number of guide blades 115. Accordingly, a smaller airflow blocking area results in less airflow loss.

[0088] By having 1 to 3 guide blades 115 in each guide blade group 116 , the airflow guiding effect of the guide blade group 116 and the air outlet resistance can be better balanced.

[0089] Reference Figure 17 and Figure 18 According to some embodiments of the present invention, in the flow direction of the airflow, part of the louver 132 is located on the upstream side of the first air guide component 11, the projection of the guide blade 115 on the reference plane is the fifth projection, the projection of the louver 132 on the reference plane is the sixth projection, the minimum distance between the fifth projection and the sixth projection is d1, the guide blade 115 is circular and the radius of the guide blade 115 is R1, the part of the louver 132 located on the upstream side of the first air guide component 11 is the upstream portion 134, the upstream portion 134 is suitable for connecting with the casing component 2a of the air conditioner, the projection of the upstream portion 134 on the reference plane is the seventh projection, the sixth projection includes the seventh projection, the maximum distance between the side of the seventh projection and the center of the fifth projection is R2, the spacing between two adjacent groups of guide blade groups 116 in the first direction is d2, and d2 satisfies: 0.92*(R2-R1-d1)≤d2≤3.5*(R2-R1-d1).

[0090] For example, d2 can be 0.92*(R2-R1-d1), 1.5*(R2-R1-d1), 2.3*(R2-R1-d1), 2.85*(R2-R1-d1), 3.5*(R2-R1-d1), etc. By ensuring that 0.92*(R2-R1-d1)≤d2, the wind resistance can be reduced as much as possible to reduce the air volume loss, and the increase in the flow resistance of the airflow due to the small spacing d2 between two adjacent groups of guide blade groups 116 in the first direction is avoided; by ensuring that d2≤3.5*(R2-R1-d1), the guiding effect of the airflow when the two adjacent groups of guide blade groups 116 are combined with the louver 132 can be ensured, and the weakening of the guiding effect on the airflow due to the large spacing between the two adjacent groups of guide blade groups 116 is avoided.

[0091] By satisfying 0.92*(R2-R1-d1)≤d2≤3.5*(R2-R1-d1), the spacing d2 of the guide blade assembly 116 in the first direction can be made more reasonable, so as to take into account both the airflow guiding effect and the air outlet resistance of the air guide assembly 1.

[0092] Reference Figure 1 、 Figure 6 and Figure 19According to some embodiments of the present invention, the louver 132 is a flexible member. Driven by the connecting rod 131, the louver 132 can be deformed to a certain extent to adjust the airflow direction of the louver 132. For example, by driving the connecting rod 131 to deform the louver 132 to a certain extent, the louver 132 can be aligned parallel to the guide vanes 115, thereby reducing airflow resistance and enhancing the airflow guidance effect.

[0093] When the louver 132 is a flexible member, the louver 132 also relies on deformation to achieve swinging of the louver 132 in the first direction to adjust the air guide direction of the louver 132. However, relying solely on the deformation of the louver 132 itself to achieve swinging in the first direction generally results in a small swing angle and cannot be increased. By using the louver 132 and the guide vane assembly 116 together, the inclination angle of the guide vane 115 can be set to a larger angle. In this way, the guide vane 115 can have a larger guide angle relative to the louver 132, which can compensate for the small swing angle of the flexible louver 132.

[0094] Taking the first direction as the up and down direction as an example, as mentioned above, due to the characteristics of the flexible louver 132, the swing angle of the flexible louver 132 in the up and down directions is small. For example, the upward swing angle and the downward swing angle of the flexible louver 132 are both small. By setting the inclined guide blade 115, the guide blade 115 can have a larger guide angle in the upward or downward direction. In this way, through the combination of the louver 132 and the guide blade 115, a larger guide range and guide angle can be provided in the up and down directions, and the wind guiding effect is better.

The second air-guiding component 13 includes a connecting rod 131 and a plurality of louvers 132 arranged along a first direction. The movement of the connecting rod 131 along the first direction can drive the louvers 132 to swing in the first direction. By adjusting the guiding direction of the airflow by the guide vanes 115 and the guiding direction of the airflow by the louvers 132, for example, the guiding directions of the guide vanes 115 and the louvers 132 can be made consistent to enhance the air-guiding effect, or the guiding directions of the guide vanes 115 and the louvers 132 can be made different to achieve diversified air outlet modes.
