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.

[0032] An air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, the air conditioner 100 according to the embodiment of the present invention includes a housing 3 , a first air guide plate 1 and a second air guide plate 2 .

[0034] Specifically, such as Figures 1-4As shown, the housing 3 has an air outlet 31 extending horizontally. The housing 3 is used to form the overall appearance of the air conditioner 100. An air outlet duct 32 is formed inside the housing 3, and the air outlet 31 is connected to the air outlet duct 32. The housing 3 may also be provided with an air inlet, which is connected to the air outlet duct 32 to allow air to enter the air outlet duct 32 through the air inlet.

[0035] like Figure 1 In the example shown, housing 3 is further provided with a heat exchanger 5, a crossflow impeller 4, and louvers 6. In the direction of airflow within air conditioner 100, heat exchanger 5 is upstream of crossflow impeller 4, while louvers 6 are downstream of crossflow impeller 4, i.e., near air outlet 31. Heat exchanger 5 is used to exchange heat with the airflow passing over it, while crossflow impeller 4 is used to drive airflow from the air inlet to the air outlet 31. Louvers 6 adjust the airflow angle along the length of air outlet 31.

[0036] During the specific operation of the air conditioner 100, driven by the cross-flow impeller 4, the outside air will enter the air outlet duct 32 in the shell 3 from the air inlet. After the heat exchange action of the heat exchanger 5, the heat-exchanged air will flow out of the air conditioner 100 from the air outlet 31 after being guided by the louver 6 to ensure the cooling, heating and air supply functions of the air conditioner 100.

[0037] Furthermore, the first air guide plate 1 is rotatably disposed at the air outlet 31, and the second air guide plate 2 is rotatably disposed at the air outlet 31. The first air guide plate 1 and the second air guide plate 2 are used to open and close the air outlet 31. It is understandable that the first air guide plate 1 and the second air guide plate 2 can be rotated to a position to open or close the air outlet 31, respectively. At the same time, the first air guide plate 1 and the second air guide plate 2 can be rotated to different angles, respectively, so that the first air guide plate 1 and the second air guide plate 2 can guide the airflow to be blown out from the air outlet 31 at different angles. Therefore, with the mutual cooperation of the first air guide plate 1 and the second air guide plate 2, the function and effect of air outlet at different angles of the air conditioner 100 can be achieved, thereby achieving different air supply states of the air conditioner 100, which can meet the diverse needs of users and thereby improve the user's comfort and experience.

[0038] The second air guide plate 2 is provided with a plurality of spaced-apart first through-holes 21. When the air outlet 31 is closed, the first and second air guide plates 1 and 2 are arranged along the width of the air outlet 31, with the first air guide plate 1 positioned above the second air guide plate 2. The first through-holes 21 can break up the airflow passing through the second air guide plate 2 and refine it into smaller air streams, making the airflow more uniform, delicate, and gentle, thereby achieving a windless airflow effect of the air conditioner 100 and enhancing the user experience.

[0039] In the related art, when the air conditioner is in windless mode, the air guide plate with multiple spaced-apart micropores completely closes the air outlet. This ensures a windless air outlet effect, but the wind resistance at the air outlet is large and the air volume is low, resulting in cooling loss. At the same time, when the crossflow impeller speed remains unchanged, the wind resistance at the air outlet is large, which increases the time it takes for the air flow in the shell to exchange heat with the heat exchanger. In high temperature and high humidity environments, the air flow temperature at the air outlet is easily lower than the dew point temperature, resulting in condensation. To avoid condensation, the air conditioner will reduce the compressor frequency, thereby reducing the cooling capacity, so that the air flow temperature at the air outlet is raised above the dew point temperature. However, reducing the compressor frequency will also cause the cooling effect of the air conditioner to deteriorate.

[0040] In the present application, when the user needs cooling but does not want to open the air, the second air guide plate 2 rotates to a position that closes the air outlet 31, and the first air guide plate 1 can rotate to a position that opens the air outlet 31. At this time, the first air guide plate 1 can guide the air to the outside of the air outlet 31. Part of the airflow in the air outlet duct 32 passes through the second air guide plate 2 and is blown out of the air outlet 31. The airflow is broken up by the first through hole 21 and forms a dispersed airflow, which can increase the turbulence state of the airflow, reduce the airflow velocity, and improve the smoothness of the airflow, thereby achieving a windless air outlet effect of the air conditioner 100.

[0041] At the same time, part of the airflow in the air outlet duct 32 is blown out of the air outlet 31 from above the second air guide plate 2 under the guidance of the first air guide plate 1, which can reduce the wind resistance at the air outlet 31. Under the premise that the speed of the crossflow impeller 4 remains unchanged, the air volume at the air outlet 31 increases, which can effectively reduce the loss of cooling capacity. At the same time, it can enhance the indoor air flow, thereby improving the cooling effect and improving the uniformity of the indoor temperature, thereby improving the user's comfort and experience. In addition, the time for heat exchange between the airflow in the shell 3 and the heat exchanger 5 is shortened, which can prevent the airflow temperature at the air outlet 31 from being lower than the dew point temperature in a high temperature and high humidity environment, thereby avoiding condensation. There is no need to reduce the compressor frequency, which can further ensure the cooling effect of the air conditioner 100.

[0042] In addition, the air volume of the air conditioner 100 in the windless mode can be adjusted by adjusting the rotation angle of the first air guide plate 1, thereby meeting different needs of users.

[0043] It should be noted that the cross-sectional shape of the first through-holes 21 on the second air guide plate 2 can be circular, polygonal, or elongated (i.e., slit-shaped), and the specific shape is not limited herein. Multiple first through-holes 21 can be arranged in an array on the second air guide plate 2. This allows for as many first through-holes 21 as possible to be arranged on the second air guide plate 2 while ensuring a certain structural strength of the second air guide plate 2. This ensures sufficient ventilation without affecting the airflow dispersion of the second air guide plate 2, thereby ensuring a sufficient airflow rate, and thus ensuring the airflow rate of the air outlet 31.

[0044] According to the air conditioner 100 of the embodiment of the present invention, a rotatable first air guide plate 1 and a rotatable second air guide plate 2 are provided at the air outlet 31 to open and close the air outlet 31, wherein the second air guide plate 2 has a plurality of spaced first through holes 21. When the second air guide plate 2 closes the air outlet 31, the air conditioner 100 can achieve a windless air outlet effect. In addition, the first air guide plate 1 can be rotated to a position where the air outlet 31 is opened, which can reduce the wind resistance at the air outlet 31 and increase the air volume, thereby effectively reducing the loss of cooling capacity. At the same time, the indoor air flow can be enhanced, thereby improving the cooling effect and improving the uniformity of the indoor temperature, thereby improving the user's comfort and experience. In addition, in a high temperature and high humidity environment, the generation of condensation can be avoided without reducing the compressor frequency, which can further ensure the cooling effect of the air conditioner 100.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the rotation axis of the first air guide plate 1 is located at one end of the first air guide plate 1 in the width direction. When the first air guide plate 1 closes the air outlet 31, the rotation axis of the first air guide plate 1 is located at one end of the first air guide plate 1 close to the second air guide plate 2.

[0046] It is understood that the first air guide plate 1 is provided with a first rotating shaft 11, and the two ends of the first air guide plate 1 in the width direction are respectively designated as the first end 12 and the second end 13. When the air outlet 31 is closed, the first air guide plate 1 is located above the second air guide plate 2, and the second end 13 is located above the first end 12. The first rotating shaft 11 is located at the first end 12 of the first air guide plate 1. Therefore, when the first air guide plate 1 opens the air outlet 31, the second end 13 of the first air guide plate 1 first rotates to the outside of the air outlet 31, and the upper end of the air outlet 31 in the width direction is opened first, which is more conducive to airflow out of the air outlet 31 and does not interfere with the second air guide plate 2. The structural arrangement is reasonable. At the same time, the rotation axis of the first air guide plate 1 is spaced apart from the two ends in the width direction of the air outlet 31, which can expand the rotation range of the first air guide plate 1, allowing the first air guide plate 1 to guide the airflow in different directions, thereby enhancing the air guiding effect of the first air guide plate 1.

[0047] In some embodiments of the present invention, Figure 2 As shown, the air conditioner 100 has a no-wind mode. In the first no-wind mode, the second air guide plate 2 is in a position to close the air outlet 31, the upper end of the first air guide plate 1 is open toward the outside of the air outlet 31, and the first air guide plate 1 is horizontally arranged or the air outlet end of the first air guide plate 1 is tilted upward.

[0048] In this way, part of the airflow in the air outlet duct 32 is blown out of the air outlet 31 after passing through the second air guide plate 2, and the airflow is broken up by the first through hole 21 to form an airflow dispersion, so as to ensure the windless air outlet effect of the air conditioner 100. At the same time, part of the airflow in the air outlet duct 32 is blown out from above the width direction of the air outlet 31 under the guidance of the first air guide plate 1, thereby reducing the wind resistance at the air outlet 31 and increasing the air volume, thereby effectively reducing the cooling loss. The first air guide plate 1 can guide the airflow to blow out of the air outlet 31 in a horizontal or obliquely upward direction, which can prevent the airflow from dropping rapidly after being blown out of the air outlet 31, thereby achieving a long-distance air supply effect and effectively preventing the airflow from blowing directly onto the user, thereby ensuring a windless blowing effect while increasing the air volume. At the same time, it can enhance the indoor air flow, help improve the cooling efficiency and improve the uniformity of the indoor temperature, thereby improving the user's comfort and experience.

[0049] In some embodiments of the present invention, Figure 4 As shown, the air conditioner 100 has a heating mode. In the heating mode, the second air guide plate 2 opens the air outlet 31, and the second air guide plate 2 rotates to the bottom of the air outlet 31 in the width direction, and the end of the first air guide plate 1 away from the rotation axis rotates to the inside of the air outlet 31, and the air outlet end of the first air guide plate 1 tilts downward.

[0050] It is understood that in the heating mode, the second air guide plate 2 rotates to the bottom of the air outlet 31 to fully open the air outlet 31. The bottom of the air outlet 31 in the width direction is completely open and will not interfere with the hot air blown downward. The shell 3 has an air outlet duct 32 connected to the air outlet 31. The air inlet end of the first air guide plate 1 is spliced ​​or close to the upper side wall of the air outlet duct 32. The air outlet end of the first air guide plate 1 is located below or obliquely below the air inlet end of the first air guide plate 1. As a result, the first air guide plate 1 can guide the hot air flow at the air outlet 31 downward, so that the hot air flow is blown downward, which is conducive to the expansion and rise of hot air and the descent of cold air, accelerating the alternation of hot and cold air flows and air circulation in the room, thereby accelerating the indoor temperature rise rate to improve the heating effect of the air conditioner 100.

[0051] In some embodiments, as Figure 1 As shown, the air conditioner 100 has an off state. In this off state, the first air guide plate 1 and the second air guide plate 2 jointly close the air outlet 31, and the air conditioner 100 stops discharging air. The first air guide plate 1 and the second air guide plate 2 are arranged along the width of the air outlet 31, with the first air guide plate 1 located above the second air guide plate 2. The first air guide plate 1, the second air guide plate 2, and the housing 3 constitute the complete appearance of the air conditioner 100. The first air guide plate 1 and the second air guide plate 2 can prevent dust, improve the cleanliness of the interior of the air conditioner 100, and enhance the appearance of the air conditioner 100.

[0052] In some embodiments, as Figure 3 As shown, the air conditioner 100 has a cooling mode. In the cooling mode, the first air guide plate 1 and the second air guide plate 2 both open the air outlet 31. The end of the first air guide plate 1 that is away from the rotation axis of the first air guide plate 1 opens toward the outside of the air outlet 31, and the end of the second air guide plate 2 that is away from the rotation axis of the second air guide plate 2 opens toward the outside of the air outlet 31. The air outlet end of the first air guide plate 1 and the air outlet end of the second air guide plate 2 are tilted downward. At this time, the first air guide plate 1 and the second air guide plate 2 can become extensions of the air outlet duct 32, which can reduce the wind resistance at the air outlet 31 inside the air outlet duct 32 to ensure the air output of the air outlet 31. The airflow at the air outlet 31 can be blown into the room under the wind guiding action of the first air guide plate 1 and the second air guide plate 2, thereby ensuring the air output and cooling effect of the air conditioner 100.

[0053] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the rotation axis of the second air guide plate 2 is located at one end of the second air guide plate 2 in the width direction. When the second air guide plate 2 closes the air outlet 31, the rotation axis of the second air guide plate 2 is located at the end of the second air guide plate 2 away from the first air guide plate 1.

[0054] It is understood that the second air guide plate 2 is provided with a second rotating shaft 22, and the two ends of the second air guide plate 2 in the width direction are respectively marked as the third end 23 and the fourth end 24. When the air outlet 31 is closed, the first air guide plate 1 is located above the second air guide plate 2, the fourth end 24 is located above the third end 23, and the second rotating shaft 22 is located at the third end 23 of the second air guide plate 2. Therefore, when the second air guide plate 2 opens the air outlet 31, the fourth end 24 of the second air guide plate 2 first rotates to the outside of the air outlet 31, which can reduce the wind resistance of the second air guide plate 2 at the air outlet 31, further facilitate the airflow out of the air outlet 31, and will not interfere with the first air guide plate 1 above, and the structural arrangement is reasonable.

[0055] In some embodiments of the present invention, Figures 1-4 As shown, the first air guide plate 1 is curved. When the first air guide plate 1 closes the air outlet 31, the first air guide plate 1 protrudes toward the outside of the air outlet 31. When the first air guide plate 1 guides air, the curved surface of the first air guide plate 1 helps concentrate the airflow and reduce wind resistance, allowing air to be delivered over a longer distance, enhancing the air supply capacity of the air conditioner and thus improving air circulation efficiency. It also allows the airflow to flow more smoothly, reducing air stagnation on the first air guide plate 1, reducing wind resistance and noise, and contributing to improved user comfort.

[0056] In some embodiments of the present invention, the first air guide plate 1 is a flat plate structure, which is simple in structure and easy to process and maintain, and can effectively reduce the materials required to produce the first air guide plate 1, thereby helping to reduce production costs.

[0057] In some embodiments, the first air guide plate 1 includes a first plate body and a second plate body stacked in the thickness direction of the first air guide plate 1, the two ends of the first plate body in the width direction are connected to the two ends of the second plate body in the width direction, and a cavity is defined between the first plate body and the second plate body. Dividing the first air guide plate 1 into the first plate body and the second plate body facilitates processing the first plate body and the second plate body into arc surfaces respectively, and then assembling and connecting them, so that the first air guide plate 1 forms a double-sided concave arc surface structure in the thickness direction, which is convenient for processing and production, and can further enhance the air guiding effect of the first air guide plate 1. At the same time, the cavity defined between the first plate body and the second plate body can effectively prevent condensation from occurring on both sides of the first air guide plate 1 in the thickness direction due to excessive temperature difference during the air guiding process. Structures such as sponges can also be provided in the cavity to further enhance the anti-condensation effect.

[0058] In some embodiments of the present invention, Figures 1-4 As shown, the second air guide plate 2 is curved. When the second air guide plate 2 closes the air outlet 31, the second air guide plate 2 protrudes toward the outside of the air outlet 31. When the second air guide plate 2 guides air, the curved surface of the second air guide plate 2 helps concentrate the airflow and reduce wind resistance, allowing air to be delivered over a longer distance, enhancing the air supply capacity of the air conditioner and thus improving air circulation efficiency. It also allows the airflow to flow more smoothly, reducing air stagnation on the second air guide plate 2, reducing wind resistance and noise, and contributing to improved user comfort.

[0059] In some embodiments of the present invention, the second air guide plate 2 is a flat plate structure, which is simple in structure and easy to process and maintain, and can effectively reduce the materials required to produce the second air guide plate 2, thereby helping to reduce production costs.

[0060] In some embodiments of the present invention, Figures 1-4 As shown, the first air guide plate 1 and the second air guide plate 2 have the same width. When the first air guide plate 1 and the second air guide plate 2 open the air outlet 31, the first air guide plate 1 and the second air guide plate 2 of the same width can ensure a more uniform air supply range and reduce the difference in air supply effect between the first air guide plate 1 and the second air guide plate 2, thereby improving the air supply effect and helping to improve the uniformity of the indoor temperature.

[0061] In some embodiments of the present invention, Figures 1-4 As shown, the first air guide plate 1 is a non-porous plate structure, which can improve the wind guiding effect of the first air guide plate 1 and is more conducive to achieving long-distance air supply under the guidance of the first air guide plate 1. In cooperation with the second air guide plate 2, it can better ensure the windless effect and increase the air supply volume.

[0062] In some embodiments of the present invention, the first air guide plate 1 is provided with a plurality of spaced-apart second through-holes. These second through-holes can break up the airflow passing through the first air guide plate 1 and refine it into smaller air streams, making the airflow more uniform, delicate, and gentle, thereby facilitating a windless airflow effect for the air conditioner 100 and enhancing the user experience. Furthermore, the airflow area at the air outlet 31 of the air conditioner 100 in windless mode can be increased, thereby increasing the windless air volume and reducing cooling loss.

[0063] It should be noted that the cross-sectional shape of the second through-holes 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 second through-holes can be arranged in an array on the first air guide plate 1. This allows for as many second through-holes as possible to be arranged on the first air guide plate 1 while maintaining 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 air flow rate, and thus ensuring the air output from the air outlet 31, thereby ensuring the air supply effect of the air conditioner 100.

[0064] In some embodiments of the present invention, along the length of the second air guide plate 2, the second air guide plate 2 is divided into a first region and a second region, arranged sequentially. In the direction from the inner surface to the outer surface of the first air guide plate 1, the first through-holes 21 in the first region and the first through-holes 21 in the second region are inclined in directions away from each other. Thus, when the air conditioner 100 is in windless mode, the second air guide plate 2 closes the air outlet 31, and at least a portion of the airflow in the air duct 32 passes through the second air guide plate 2 and then blows out of the air outlet 31. The first through-holes 21 in the first region and the first through-holes 21 in the second region can guide the airflow in directions away from each other, i.e., the airflow passing through the second air guide plate 2 flows toward both ends of the length of the second air guide plate 2. This can further prevent the airflow from blowing directly onto the user, further enhancing the windless airflow effect of the air conditioner 100 while ensuring the airflow volume, thereby enhancing the user's comfort and experience.

[0065] In some embodiments of the present invention, the second air guide plate 2 includes a third region and a fourth region. The third and fourth regions are arranged across the width of the second air guide plate 2. When the air outlet 31 is closed, the third region is located on the side of the fourth region closest to the first air guide plate 1. Both the third and fourth regions are provided with first through-holes 21, and the density of first through-holes 21 in the third region is lower than that in the fourth region. This results in a greater wind resistance in the third region than in the fourth region, and a lower air volume in the third region near the first air guide plate 1 than in the fourth region. This further enhances the wind-free airflow of the air conditioner 100 based on actual user experience. For example, if the third region is positioned above the fourth region, when the air outlet 31 is closed on the second air guide plate 2, the air volume near the upper portion of the air outlet 31 is reduced across the width of the air outlet 31, further enhancing the wind-free airflow and user comfort.

[0066] In another embodiment, along the length direction of the second air guide plate 2, the density of the first through holes 21 at the ends of the second air guide plate 2 in the length direction is greater than the density of the first through holes 21 in the middle region of the second air guide plate 2. Thus, along the length direction of the second air guide plate 2, the wind resistance at the ends of the second air guide plate 2 in the length direction is less than the wind resistance in the middle region of the second air guide plate 2, and the air volume at the ends of the second air guide plate 2 in the length direction is greater than the air volume in the middle region of the second air guide plate 2. This can better prevent the airflow from the air outlet in the middle region of the second air guide plate 2 from directly blowing onto the user, further enhancing the windless air outlet effect of the air conditioner 100, and thus further improving the user's comfort.

[0067] In some embodiments of the present invention, the air conditioner 100 further includes a third air guide plate, which is rotatably disposed at the air outlet 31. When the first air guide plate 1 and the second air guide plate 2 close the air outlet 31, the third air guide plate is located inside the first air guide plate 1 and the second air guide plate 2. The width of the third air guide plate is smaller than that of the first air guide plate 1 and the second air guide plate 2. The third air guide plate can change the air guide direction by rotating, directing the airflow within the air outlet duct 32 of the air conditioner 100 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 100, thereby achieving different air supply states of the air conditioner 100, 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.

[0068] Other components of the air conditioner 100 according to the embodiment of the present invention, such as the heat exchanger 5 , the crossflow impeller 4 and the louvers 6 , are well known to those skilled in the art and will not be described in detail here.
