[0040] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0041] The wind guide structure 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] like Figure 1 and Figure 2 As shown, the air guide structure 100 according to an embodiment of the present invention includes a first air guide plate 1 and a rotating drum structure 2 .

[0043] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the air guide structure 100 is used for an air conditioner 200. The air conditioner 200 includes a housing 3 having an air outlet 31. The housing 3 is used to form the overall appearance of the air conditioner 200. An air outlet duct 33 is formed inside the housing 3, and the air outlet 31 is connected to the air outlet duct 33. The top of the housing 3 may also be provided with an air inlet 32, which is connected to the air outlet duct 33 to allow air to enter the air outlet duct 33 through the air inlet 32.

[0044] like Figure 1In the example shown, housing 3 is further provided with a heat exchanger 7, a crossflow impeller 6, and louvers 8. In the direction of airflow within air conditioner 200, heat exchanger 7 is upstream of crossflow impeller 6, while louvers 8 are downstream of crossflow impeller 6, i.e., near air outlet 31. Heat exchanger 7 is used to exchange heat with the airflow passing over its surface. Crossflow impeller 6 is used to drive airflow from air inlet 32 ​​to air outlet 31. Louvers 8 adjust the outlet angle of the airflow along the length of air outlet 31.

[0045] During the specific operation of the air conditioner 200, driven by the cross-flow impeller 6, the outside air will enter the air outlet duct 33 in the shell 3 from the air inlet 32. After the heat exchange action of the heat exchanger 7, the heat-exchanged air will flow out of the air conditioner 200 from the air outlet 31 after being guided by the louver 8, so as to ensure the cooling, heating and air supply functions of the air conditioner 200.

[0046] Furthermore, an air guide structure 100 is provided at the air outlet 31 for opening or closing the air outlet 31. A first air guide plate 1 is rotatably provided at the air outlet 31 and has a plurality of spaced-apart through-holes 11 therein. A rotary drum structure 2 is rotatably provided at the air outlet 31. When the air outlet 31 is closed, the first air guide plate 1 and the rotary drum structure 2 are arranged in the width direction of the air outlet 31.

[0047] It is understandable that the first air guide plate 1 and the drum structure 2 can be rotated to open or close the air outlet 31, respectively. Figure 1 In the example shown, when the air guide structure 100 closes the air outlet 31, the first air guide plate 1 and the drum structure 2 are both rotated to the position of closing the air outlet 31, and the first air guide plate 1 and the drum structure 2 are arranged in the width direction of the air outlet 31. Figure 2 and Figure 3 In the example shown, when the air guide structure 100 opens the air outlet 31 , at least one of the first air guide plate 1 and the drum structure 2 rotates to a position where the air outlet 31 is opened.

[0048] Among them, the first air guide plate 1 has a plurality of spaced-apart through holes 11, which can break up the airflow flowing through the first air guide plate 1 and refine it into a smaller air flow, making the airflow more uniform, delicate and soft, which is conducive to achieving the windless air outlet effect of the air conditioner 200, so as to enhance the user experience.

[0049] For example, Figure 1As shown, when the user has a cooling demand but does not want to blow air, the first air guide plate 1 and the drum structure 2 can be rotated to a position where the air outlet 31 is closed together, and the airflow in the air outlet duct 33 is blown out of the air outlet 31 after passing through the first air guide plate 1. The airflow is broken up by the through hole 11 and forms an airflow dispersion, which can improve the turbulent state of the airflow flow process, and at the same time can reduce the airflow velocity and improve the smoothness of the airflow flow, thereby improving the comfort of the air outlet, so that the airflow will not be blown directly to the user after being blown out of the air outlet 31, thereby achieving a windless air outlet effect of the air conditioner 200 to meet the needs of the user, thereby improving the user's comfort and experience.

[0050] Furthermore, if Figure 2 In the example shown, when a user requires cooling but does not want to use direct airflow and requires a high air volume, first air guide plate 1 rotates to close air outlet 31, and drum structure 2 rotates to open air outlet 31. At this point, drum structure 2 can direct air outward from air outlet 31. A portion of the airflow within outlet duct 33 passes through first air guide plate 1 and then out of air outlet 31. This airflow is then dispersed by through-holes 11, forming a diffused flow to ensure a windless airflow from air conditioner 200. Simultaneously, a portion of the airflow within outlet duct 33 passes through drum structure 2 and out of air outlet 31, thereby increasing the air volume.

[0051] and Figure 1 Compared to the example shown, rotating the drum structure 2 to open the air outlet 31 can reduce the wind resistance at the air outlet 31. Under the premise that the speed of the crossflow impeller 6 remains unchanged, the air volume at the air outlet 31 increases, and the time for the airflow in the shell 3 to exchange heat with the heat exchanger 7 is shortened, which can prevent the airflow from being too low in temperature. In addition, it can prevent the supercooled airflow from being dispersed and sinking after passing through the first air guide plate 1, causing discomfort to the user's localized parts near the ground, such as the ankles and calves. At the same time, the drum structure 2 increases the air volume, which can enhance indoor air flow, improve the cooling effect and increase the uniformity of indoor temperature, further improving the user's comfort and experience.

[0052] It should be noted that the cross-sectional shape of the through holes 11 on the first air guide plate 1 can be circular, polygonal, or elongated (i.e., slits), and the specific shape is not limited herein. Multiple through holes 11 can be arranged in an array on the first air guide plate 1. This allows for as many through holes 11 as possible to be arranged on the first air guide plate 1 while ensuring a certain structural strength of the first air guide plate 1. This ensures sufficient ventilation without affecting the airflow dispersion of the first air guide plate 1, thereby ensuring a sufficient airflow rate, and thus ensuring the airflow rate of the air outlet 31.

[0053] According to the air guide structure 100 of the embodiment of the present invention, the air guide structure 100 is arranged at the air outlet 31 of the air conditioner 200 to open or close the air outlet 31, and a rotatable first air guide plate 1 and a rotatable drum structure 2 are arranged at the air outlet 31, wherein the first air guide plate 1 has a plurality of spaced through holes 11. When the first air guide plate 1 closes the air outlet 31, the air conditioner 200 can achieve a windless air outlet effect. In addition, the drum structure 2 can be switched between the open air outlet 31 and the closed air outlet 31 by adjusting the angle of the drum structure 2, thereby adjusting the air outlet volume in the windless mode to meet the different needs of users, thereby improving the user's comfort and experience.

[0054] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, the drum structure 2 includes a first connecting plate, a second connecting plate, and a guide plate 21. The first and second connecting plates are spaced apart along the length of the air outlet 31 and are both rotatably mounted on the housing 3. A plurality of guide plates 21 are spaced apart in the thickness direction of the guide plates 21. A guide channel 22 is defined between two adjacent guide plates 21. The ends of the guide plates 21 in the length direction are connected to the first and second connecting plates, respectively. When the air outlet 31 is closed, one of the guide plates 21 located on either side of the guide plate 21 in the thickness direction is used to close the air outlet 31.

[0055] It is understood that the first and second connecting plates can connect the multiple guide plates 21 together, so that the multiple guide plates 21 form a whole. When the first and second connecting plates rotate, they can drive the multiple guide plates 21 to rotate together, thereby achieving the overall rotatable positioning of the drum structure 2 at the air outlet 31 to open or close the air outlet 31. The structure is simple and the layout is reasonable. The first and second connecting plates can be provided with a rotating shaft. The air conditioner 200 is provided with a drive motor. The output shaft of the drive motor is connected to the rotating shaft to drive the first and second connecting plates to rotate, thereby driving the rotation of the drum structure 2.

[0056] The housing 3 includes an outlet duct 33 connected to the air outlet 31. The guide channel 22 is connected to the outlet duct 33. When the drum structure 2 rotates to a position that closes the air outlet 31, one of the guide plates 21 located on either side of the guide plate 21 in the thickness direction rotates to a position that closes the air outlet 31, thereby preventing the guide channel 22 from connecting to the air outlet 31. When the drum structure 2 rotates to a position that opens the air outlet 31, the guide channel 22 connects to the air outlet 31. At this time, the guide plates 21 can act as a guide, allowing some of the airflow in the outlet duct 33 to flow out of the air outlet 31 through the guide channel 22. This allows the air volume to be increased while maintaining the wind-free airflow of the air conditioner 200 when the first guide plate 1 rotates to a position that closes the air outlet 31.

[0057] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, multiple deflectors 21 protrude toward the same side in the thickness direction of the deflector 21. The curved surfaces of the multiple deflectors 21 help concentrate airflow and reduce wind resistance, extending the air supply distance and improving the air guiding effect of the multiple deflectors 21. At the same time, the multiple deflectors 21 can form guide channels 22 that protrude toward the same side in the thickness direction of the deflector 21. When the rotary drum structure 2 opens the air outlet 31, the multiple deflectors 21 can follow the direction of the airflow and guide part of the airflow in the air outlet duct 33 to the side of the air outlet 31 in the width direction away from the first air deflector 1 and blow it out, thereby ensuring the effect of increasing the airflow volume. The airflow in the multiple guide channels 22 has a roughly uniform flow direction, which can reduce wind resistance while ensuring the air guiding effect of the deflectors 21, extending the air supply distance of the rotary drum structure 2, and preventing the airflow blown out from the rotary drum structure 2 from directly blowing on the user, thereby ensuring a windless air outlet effect and helping to improve indoor temperature uniformity.

[0058] In addition, it should be noted that the curvature of the multiple guide plates 21 is moderate, so that when the drum structure 2 opens the air outlet 31, it can avoid the formation of negative pressure at the end of the guide plate 21 close to the air outlet duct 33 due to the guide plate 21 being too curved, thereby avoiding the phenomenon of backflow in the drum structure 2.

[0059] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 3As shown, the deflector plate 21 located at the outermost edge of the protruding direction of the deflector 21 among the multiple deflectors 21 is thicker than the thickness of the remaining deflectors 21 and is used to close the air outlet 31. This improves the structural strength of the deflector plate 21 located at the outermost edge of the protruding direction of the deflector 21. When the rotating drum structure 2 closes the air outlet 31, the deflector plate 21 located at the outermost edge of the protruding direction of the deflector 21 can block at least part of the airflow outflow at the air outlet 31, thereby better ensuring the wind-free air outlet effect of the first deflector 1.

[0060] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, the width of the guide channel 22 gradually increases from one end to the other end along the width direction of the guide plate 21, thereby enhancing the wind guiding effect of the drum structure 2 when the drum structure 2 opens the air outlet 31. Figure 1 As shown, when the rotating drum structure 2 closes the air outlet 31, the wider end of the guide channel 22 rotates to the inside of the air outlet 31. At this time, the guide plate 21 at the edge closes the air outlet 31, and no air flows out of the air outlet 31 at the rotating drum structure 2, which can ensure a windless air outlet effect.

[0061] like Figure 2 As shown, when the rotating drum structure 2 opens the air outlet 31, the wider end of the guide channel 22 rotates to the air outlet 31, and the narrower end of the guide channel 22 rotates to the inside of the air outlet 31. This allows the air outlet duct 33, the guide channel 22, and the air outlet 31 to be connected. In the direction of airflow, the guide channel 22 gradually widens, which helps reduce wind resistance and increase the air outlet area, thereby better increasing the air volume and improving the uniformity of indoor temperature. In addition, the air inlet ends of multiple guide plates 21 are closer together, which can ensure the uniformity of airflow within each guide channel 22, thereby avoiding temperature differences caused by low airflow in individual guide channels 22 and preventing condensation on the guide plates 21.

[0062] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 3As shown, the housing 3 has an outlet duct 33 in communication with the air outlet 31. A volute tongue 34 is provided on one of the two inner walls of the outlet duct 33 that face each other in the width direction. The rotor structure 2 is provided on the side of the outlet 31 that is closer to the volute tongue 34 in the width direction. It is understood that, influenced by factors such as the position of the crossflow impeller 6 and the direction of the driving force, the airflow in the outlet duct 33 flows toward the inner wall of the side closer to the volute tongue 34 in the direction from the crossflow impeller 6 to the air outlet 31, that is, toward the direction closer to the rotor structure 2 of the air outlet 31. Therefore, when the rotor structure 2 opens the air outlet 31, the airflow in the outlet duct 33 is facilitated to flow out of the outlet 31 from the rotor structure 2, thereby increasing the air volume, and demonstrating a reasonable structural design.

[0063] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, the inner wall of the air outlet duct 33, which has the volute 34, has a recessed portion 331. The recessed portion 331 is located at one end of the air outlet duct 33 near the air outlet 31 and is in communication with the air outlet 31. The rotary drum structure 2 is rotatably disposed within the recessed portion 331. This allows for greater utilization of the space within the housing 3, improving space utilization within the housing 3. This allows the rotary drum structure 2 to be positioned entirely within the interior of the air outlet 31, preventing the rotary drum structure 2 from occupying space outside the housing 3 and improving the aesthetic appearance of the air conditioner 200. Furthermore, when the air outlet 31 is opened, the rotary drum structure 2 facilitates directing the airflow within the air outlet duct 33 out of the air outlet 31, thereby enhancing the air guiding effect.

[0064] In some embodiments of the present invention, Figure 2 As shown, the air outlet 31 extends horizontally, and the rotary drum structure 2 is located at the upper end of the air outlet 31. When the air outlet 31 is closed, the rotary drum structure 2 is located above the first air guide plate 1. Therefore, when the first air guide plate 1 rotates to close the air outlet 31 and the rotary drum structure 2 rotates to open the air outlet 31, part of the airflow in the air outlet duct 33 is blown out from above the width of the air outlet 31 through the rotary drum structure 2. This can achieve a long-range air supply effect and prevent the airflow from directly blowing on the user. This increases the airflow volume while ensuring a windless blowing effect. This solves the problem of large temperature differences between the near and far areas of the air conditioner 200, improves the uniformity of the indoor temperature, and thus enhances the user's comfort.

[0065] In some embodiments of the present invention, Figure 1As shown, the air conditioner 200 has a first windless state. In this state, the drum structure 2 and the first air guide plate 1 jointly close the air outlet 31. The airflow in the air outlet duct 33 passes through the first air guide plate 1 and is blown out of the air outlet 31. The airflow is broken up by the through holes 11 and forms a dispersed airflow, which can improve the turbulence state during the airflow flow, reduce the airflow velocity, and improve the smoothness of the airflow, thereby improving the comfort of the airflow. After the airflow is blown out of the air outlet 31, it will not blow directly towards the user. In this way, the air conditioner 200 can achieve a windless air outlet effect to meet the needs of the user, thereby improving the user's comfort and experience.

[0066] In some embodiments of the present invention, Figure 2 As shown, air conditioner 200 has a second, windless state. In this second, windless state, first air guide plate 1 closes air outlet 31, and drum structure 2 directs air toward the outside of air outlet 31. A portion of the airflow within outlet duct 33 passes through first air guide plate 1 and is blown out of air outlet 31. The airflow is dispersed by through-holes 11, forming a diffused flow, ensuring a windless airflow from air conditioner 200. Simultaneously, a portion of the airflow within outlet duct 33 passes through drum structure 2 and is blown out of air outlet 31 from the upper end. This reduces wind resistance at air outlet 31 and increases airflow volume. The airflow from drum structure 2 also creates a long-range air delivery effect, preventing the airflow from directly hitting the user. This increases airflow volume while maintaining a windless airflow effect. This also enhances indoor airflow, facilitates heat exchange, and improves indoor temperature uniformity, further enhancing user comfort and user experience.

[0067] In some embodiments, as Figure 1 As shown, the air conditioner 200 has a shutdown state. In the shutdown state, the first air guide plate 1 and the drum structure 2 jointly close the air outlet 31. At this time, the air conditioner 200 stops discharging air. The first air guide plate 1, the drum structure 2 and the shell 3 constitute the complete appearance of the air conditioner 200. The first air guide plate 1 and the drum structure 2 can play a dust-proof effect, which can improve the cleanliness of the interior of the air conditioner 200 and also improve the appearance of the air conditioner 200.

[0068] In some embodiments, as Figure 3 As shown, the air conditioner 200 has an air outlet state. In the air outlet state, the drum structure 2 is in a state of closing the air outlet 31, and the first air guide plate 1 opens the air outlet 31 and rotates to the bottom of the air outlet 31 in the width direction, which can ensure that the air outlet volume of the air outlet 31 meets the user's blowing needs.

[0069] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 3As shown, a limit plate 4 extending along the length direction of the air outlet 31 is provided at the air outlet 31, and both ends of the limit plate 4 in the length direction are connected to the shell 3 and are spaced apart from both ends in the width direction of the air outlet 31. The rotating drum structure 2 and the first air guide plate 1 are respectively arranged on both sides of the limit plate 4 along the width direction of the air outlet 31. When the air outlet 31 is closed, the end of the first air guide plate 1 close to the rotating drum structure 2 is against the surface of the limit plate 4 facing the outside of the air outlet 31.

[0070] It is understandable that the limiting plate 4 can divide the air outlet 31 into two parts in the width direction of the air outlet 31, thereby limiting the first air guide plate 1 and the drum structure 2, and at the same time increasing the structural stability of the shell 3 at the air outlet 31. When the air guide structure 100 closes the air outlet 31, the end of the first air guide plate 1 close to the drum structure 2 abuts against the surface of the limiting plate 4 facing the outside of the air outlet 31, and the side surface of the guide plate 21 of the drum structure 2 used to close the air outlet 31 close to the first air guide plate 1 abuts against the end surface of the limiting plate 4 facing away from the first air guide plate 1. This ensures that the first air guide plate 1 and the drum structure 2 have a closing effect on the air outlet 31, thereby improving the dust prevention effect.

[0071] In some embodiments of the present invention, the first air guide plate 1 has a first region and a second region, which are arranged in the width direction of the first air guide plate 1. When the air outlet 31 is closed, the first region is located on the side of the second region near the drum structure 2. Both the first and second regions are provided with through holes 11, and the density of through holes 11 in the first region is less than that in the second region. As a result, the wind resistance of the first region is greater than that of the second region, and the air volume of the first region near the drum structure 2 is less than that of the second region. This can further enhance the wind-free airflow effect of the air conditioner 200 based on actual user experience. For example, if the first region is arranged above the second region, when the air outlet 31 is closed by the air guide structure 100, the air volume of the air outlet near the top of the air outlet 31 can be reduced in the width direction of the air outlet 31, thereby further improving the wind-free airflow effect and user comfort.

[0072] In another embodiment, along the length direction of the first air guide plate 1, the density of the through holes 11 at the ends of the first air guide plate 1 along the length direction is greater than the density of the through holes 11 in the middle region of the first air guide plate 1. Thus, along the length direction of the first air guide plate 1, the wind resistance at the ends of the first air guide plate 1 along the length direction is less than the wind resistance in the middle region of the first air guide plate 1, and the air volume at the ends of the first air guide plate 1 along the length direction is greater than the air volume in the middle region of the first air guide plate 1. This can better prevent the airflow from the air outlet in the middle region of the first air guide plate 1 from directly blowing onto the user, further enhancing the windless air outlet effect of the air conditioner 200, and thus further improving the user's comfort.

[0073] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, the air guide structure 100 further includes a second air guide plate 5, which is rotatably disposed at the air outlet 31. When the air outlet 31 is closed, the second air guide plate 5 is located inside the first air guide plate 1. The width of the second air guide plate 5 is smaller than that of the first air guide plate 1. The second air guide plate 5 can change the air guide direction by rotating, directing the airflow within the air outlet duct 33 of the air conditioner 200 in different directions at the air outlet 31. This can achieve the function and effect of air outlet at different angles of the air conditioner 200, thereby realizing different air supply states of the air conditioner 200, improving the richness of the air conditioning air outlet effect, meeting the diverse needs of users, and thereby improving the user's comfort and experience.

[0074] The air conditioner 200 according to the embodiment of the present invention includes: the above-mentioned air guide structure 100 .

[0075] According to the air conditioner 200 of the embodiment of the present invention, the air guide structure 100 is arranged at the air outlet 31 of the air conditioner 200 to open or close the air outlet 31, and a rotatable first air guide plate 1 and a rotatable drum structure 2 are arranged at the air outlet 31, wherein the first air guide plate 1 has a plurality of spaced through holes 11. When the first air guide plate 1 closes the air outlet 31, the air conditioner 200 can achieve a windless air outlet effect. In addition, the drum structure 2 can be switched between the open air outlet 31 and the closed air outlet 31 by adjusting the angle of the drum structure 2, thereby adjusting the air outlet volume in the windless mode to meet the different needs of users, thereby improving the user's comfort and experience.

[0076] Other components of the air conditioner 200 according to the embodiment of the present invention, such as the heat exchanger 7 , the crossflow impeller 6 and the louvers 8 , are well known to those skilled in the art and will not be described in detail here.
