[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0020] In related technologies, when an air conditioner delivers air, the air outlet panel of the air outlet assembly has parallel top and bottom walls, forming an air outlet channel between them. An air guide plate is positioned within this channel to adjust the airflow direction. However, in cooling or heating modes, airflow easily generates vortices at the top or bottom walls, leading to poor airflow guidance and control performance of the air outlet assembly.

[0021] The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0022] This application provides an air outlet component, such as... Figure 1-7 As shown, the air outlet assembly includes an air outlet panel 11 and an air guide plate 12.

[0023] The air outlet panel 11 has an air outlet channel and includes a top wall 111 and a bottom wall 112. The top wall 111 includes a first guide surface 1111, a second guide surface 1112 and a third guide surface 1113 connected sequentially from the air inlet side to the air outlet side. The second guide surface 1112 is inclined upward at an angle α of 30° to 60°. The bottom wall 112 includes a fourth guide surface 1121, a fifth guide surface 1122 and a sixth guide surface 1123 connected sequentially from the air inlet side to the air outlet side. The sixth guide surface 1123 is inclined downward at an angle b of 30° to 60°.

[0024] The air guide plate 12 is rotatably installed inside the air outlet panel 11 and close to the air outlet side, and is used to adjust the up and down air direction.

[0025] In the air outlet assembly provided in this application embodiment, the top wall 111 of the air outlet panel 11 includes a first guide surface 1111, a second guide surface 1112, and a third guide surface 1113 connected sequentially from the air inlet side to the air outlet side. The upward tilt angle α of the second guide surface 1112 includes 30°~60°, and the upward tilt angle α of the second guide surface 1112 includes upper and lower limits. The bottom wall 112 includes a fourth guide surface 1121, a fifth guide surface 1122, and a sixth guide surface 1123 connected sequentially from the air inlet side to the air outlet side. The downward tilt angle b of the sixth guide surface 1123 includes 30°~60°, and the downward tilt angle b of the sixth guide surface 1123 includes upper and lower limits. Thus, the dimensions of the air outlet channel in the vertical direction gradually increase from the air inlet side to the air outlet side. The gradual increase in size allows the airflow to gradually diffuse; the smooth transition between each guide surface prevents airflow separation and maintains airflow uniformity; the air guide plate 12 is rotatably installed inside the air outlet panel 11 and close to the air outlet side. In cooling mode, the air guide plate 12 rotates upward to deflect the airflow, and with the tilt angle design of the second guide surface 1112, it can guide the airflow on the air outlet side to travel along the ceiling, improving cooling efficiency; in heating mode, the air guide plate 12 rotates downward to deflect the airflow, and with the tilt angle design of the sixth guide surface 1123, it can guide the airflow on the air outlet side to travel along the ground, improving heating efficiency; it achieves the dual effects of long-distance air delivery and uniform diffusion, and can reduce turbulence and wind resistance, thereby improving the air guiding and control effect.

[0026] Optionally, in this embodiment, the first guide surface 1111 and the fourth guide surface 1121 are parallel to each other and both extend horizontally to ensure the stability of the intake airflow; the second guide surface 1112 is inclined upward at a greater angle than the fifth guide surface 1122 is inclined downward, and the third guide surface 1113 is inclined upward at a less than the sixth guide surface 1123 is inclined downward, thereby forming a gradually expanding guide structure in the air outlet channel, so that the pressure gradient is reasonably distributed during the airflow process, reducing the turbulence intensity of the airflow. Through the synergistic effect of the second guide surface 1112 and the sixth guide surface 1123, the airflow adhesion effect is enhanced, the air delivery distance is extended, and the air guiding accuracy and response speed in the vertical direction are improved, thereby improving the air guiding effect.

[0027] In addition, the third guide surface 1113 and the sixth guide surface 1123 form an asymmetric diffusion angle on the air outlet side, which can effectively guide the airflow to travel along the set trajectory to adhere to the ceiling or the ground, thereby improving the air control effect.

[0028] It should be noted that, in this embodiment, the top wall 111 is closer to the ceiling, and the bottom wall 112 is closer to the ground. In this embodiment, the angle at which each guide surface is tilted upward or downward refers to the angle between the guide surface and the horizontal direction. For example, the angle α at which the second guide surface 1112 is tilted upward refers to the angle between the second guide surface 1112 and the horizontal direction. Figure 3 and Figure 5 The direction of the middle arrow indicates the direction of the airflow, with one side being the air outlet side and the other side being the air inlet side.

[0029] Alternatively, in one possible implementation of this application, such as Figure 3-4 As shown, in cooling mode, the maximum upward angle c of the air guide plate 12 rotating upward includes 32°~48°.

[0030] In this embodiment, the air guide plate 12 is disposed within the air outlet panel 11 and close to the air outlet side. The air guide plate rotates to form an air outlet. In the air conditioner's cooling mode, the air guide plate 12 rotates upward, with a rotation angle range of 0~48°, including both upper and lower limits. The maximum upward angle c of the air guide plate 12 rotation ranges from 32° to 48°, also including both upper and lower limits. When the air guide plate 12 rotates upward to its maximum angle, the airflow, guided by the second guide surface 1112 and the third guide surface 1113, is blown out through the air outlet and extends close to the ceiling, forming an attached airflow layer. This allows the cold air to be transported over a long distance along the ceiling, increasing the transport distance of the cold air while avoiding direct blowing on the human body and causing discomfort. As the airflow speed decreases, the cold air gradually and naturally sinks, achieving a uniform indoor temperature distribution and avoiding localized overcooling or temperature stratification, thereby increasing comfort.

[0031] Alternatively, in one possible implementation of this application, such as Figure 3-4 As shown, there are at least two air guide plates 12. When the air guide plates 12 are rotated upward to the maximum upward angle c, the minimum distance L between the front end of the uppermost air guide plate 12 and the end of the third guide surface 1113 located on the air outlet side in the vertical direction includes 16~24mm.

[0032] In this embodiment, the vertical direction refers to the vertical direction between the ground and the ceiling. In cooling mode, when the air guide plate 12 rotates upward to its maximum angle, in the vertical direction, the uppermost air guide plate 12 is closest to the top of the third guide surface 1113. The minimum distance L between the uppermost air guide plate 12 and the third guide surface 1113 on the air outlet side includes 16~24mm, and this distance range includes the upper and lower limits. This distance L setting can avoid airflow blockage due to the small gap between the air guide plate 12 and the top of the air outlet (i.e., the third guide surface 1113 on the air outlet side), and can also ensure that the airflow forms a stable wall attachment effect at the air outlet, thereby improving the air delivery efficiency and air guiding accuracy. This design, combined with the upward tilting structure of the second guide surface 1112 and the third guide surface 1113, can optimize the airflow distribution and enhance the long-distance air delivery capability and temperature field uniformity in cooling mode. It should be noted that in cooling mode, the front end of the uppermost air guide plate 12 is the top of the air guide plate 12.

[0033] Alternatively, in one possible implementation of this application, such as Figure 6-7 As shown, in heating mode, the maximum downward angle d of the air guide plate 12 rotating downward includes 48°~72°.

[0034] In this embodiment, during the air conditioner's heating mode, the air guide plate 12 rotates downwards, with a rotation angle range of 0~72°, including both upper and lower limits. The maximum downward angle d of the air guide plate 12 ranges from 48° to 72°, also including both upper and lower limits. When the air guide plate 12 rotates downwards to its maximum angle, the airflow, guided by the fifth guide surface 1122 and the sixth guide surface 1123, extends close to the ground after being blown out of the air outlet, forming an attached airflow layer. This allows the hot air to be transported over a long distance along the ground, increasing the transport distance and improving the heating efficiency of the lower part of the room. This avoids the discomfort of the head being overheated and the feet being cold due to the rising of hot air. As the airflow speed decreases, the hot air gradually and naturally rises, achieving a uniform temperature distribution in the vertical direction of the room and improving the problem of uneven heating. During this process, the lowermost air guide plate 12, together with the fifth guide surface 1122 and the sixth guide surface 1123, guides the airflow downwards, optimizing the air outlet angle and flow field structure, enhancing the downward pressure effect of the hot air, and improving heating comfort.

[0035] Alternatively, in one possible implementation of this application, such as Figure 6-7 As shown, the bottom wall 112 also includes a seventh guide surface 1124 connected to the sixth guide surface 1123.

[0036] The air guide plate 12 has at least two, and when the air guide plate 12 is rotated downward to the maximum downward angle d, the minimum distance H between the front end of the lowermost air guide plate 12 and the end of the sixth guide surface 1123 that is connected to the seventh guide surface 1124 in the vertical direction includes 19.2~28.8mm.

[0037] In this embodiment, the sixth guide surface 1123 and the seventh guide surface 1124 are connected along the air inlet side to the air outlet side. The seventh guide surface 1124 is parallel to the ground. In the vertical direction, the bottom end of the sixth guide surface 1123 near the air outlet side is connected to the seventh guide surface 1124. The seventh guide surface 1124 is disposed between the sixth guide surface 1123 and the decorative panel 13. The seventh guide surface 1124 abuts against the decorative panel 13 to prevent the decorative panel 13 from collapsing backward and interfering with the air guide plate 12.

[0038] In this embodiment, during heating mode, when the air guide plate 12 rotates downward to its maximum angle, the lowest air guide plate 12 is closest to the top of the sixth guide surface 1123 in the vertical direction. The minimum distance H between the lowest air guide plate 12 and the bottom end of the sixth guide surface 1123 near the air outlet side includes 19.2~28.8mm, and this distance range includes the upper and lower limits. This distance H ensures that a stable airflow channel is formed between the air guide plate 12 and the sixth guide plate 1123. This avoids airflow blockage caused by insufficient gap between the air guide plate 12 and the bottom end of the air outlet (i.e., the bottom end of the sixth guide surface 1123 near the air outlet side), and also ensures that the airflow forms a stable wall adhesion effect at the air outlet, thereby improving air delivery efficiency and air guidance accuracy. This design, combined with the downward tilting structure of the sixth guide surface 1123, optimizes airflow distribution and enhances long-distance air delivery capability and temperature field uniformity in heating mode. It should be noted that, in the embodiments of this application, in the heating mode, the front end of the lowest air guide plate 12 is the top end of the air guide plate 12; since the seventh guide surface 1124 is horizontally set, the minimum distance H between the front end of the lowest air guide plate 12 and the end of the sixth guide surface 1123 used to connect with the seventh guide surface 1124 includes 19.2~28.8mm, that is, the minimum distance H between the front end of the lowest air guide plate 12 and the seventh guide surface 1124 includes 19.2~28.8mm.

[0039] Alternatively, in one possible implementation of this application, such as Figure 1-3 and Figure 5-6 As shown, the air outlet assembly also includes a decorative panel 13; the decorative panel 13 includes a main frame 131 and a grille 132; the main frame 131 is detachably covered on the air outlet side of the air outlet panel 11, and the grille 132 and the air guide plate 12 are both arranged along the length direction of the air outlet panel 11.

[0040] In this embodiment, the air outlet panel 11 further includes a decorative end plate 113, which is disposed on the air outlet side. The decorative end plate 113 is connected to the end of the top wall 111 near the air outlet side and the end of the bottom wall 112 near the air outlet side, respectively. The decorative end plate 113 extends in the length direction of the air outlet panel 11. The air outlet panel 11 also includes two side walls between the top wall 111 and the bottom wall 112. The top wall 111, the bottom wall 112 and the two side walls together form a main frame. The air guide plate 12 is disposed in the main frame. The decorative end plate 113 is hollow, and the decorative end plate 111 is disposed on the air outlet side of the main frame. The decorative panel 13 covers the air outlet side of the decorative end plate 113. The main frame 13 is detachably connected to the decorative end plate 113, and part of the main frame 13 is located in the hollow part of the decorative end plate 113. The grille 132 is arranged in the main frame 131 along the length of the air outlet panel 13 and is fixedly connected to the main frame 131. Along the air inlet side to the air outlet side, the air guide plate 12 is located inside the grille 132, that is, the air guide plate 12 is closer to the air inlet side than the grille 132, making the air outlet assembly more aesthetically pleasing.

[0041] Alternatively, in one possible implementation of this application, such as Figure 3-4 As shown, the air guide plate 12 has at least two. In the cooling mode, when the air guide plate 12 is rotated upward to the maximum upward angle c, the air guide area extends obliquely upward along the uppermost air guide plate 12 and is located above the uppermost grille 132.

[0042] In this embodiment, multiple air guide plates 12 are evenly arranged in the vertical direction, and each air guide plate 12 extends along the length of the air outlet panel 11. In the cooling mode, when each air guide plate 12 rotates synchronously to the maximum upward tilt angle c, the air guiding area corresponding to the air guiding angle of the uppermost air guide plate 12 is located above the uppermost grille 132, which can prevent the uppermost grille 132 from blocking the airflow and ensure that the airflow is smoothly discharged upward, thereby increasing the air volume and wind speed, and thus improving the indoor air circulation efficiency.

[0043] In some embodiments, in cooling mode, when the air guide plate 12 rotates upward to the maximum angle c, pointing from the air inlet side to the air outlet side, the minimum distance between the end of the air guide plate 12 closest to the main frame 131 and the surface of the main frame 131 away from the air guide plate 12 includes 7mm, so as to ensure that the air guide plate 12 maintains a reasonable gap with the main frame 131 at the maximum upward angle, thereby avoiding motion interference.

[0044] Alternatively, in one possible real-time mode of this application, such as Figure 6-7As shown, the air guide plate 12 has at least two air guide areas that extend obliquely downward along the lowest air guide plate 12 when the air guide plate 12 is rotated downward to the maximum downward angle d in the heating mode, and are located below the lowest grille 132.

[0045] In this embodiment of the application, when each air guide plate 12 rotates synchronously to the maximum downward tilt angle d in the heating mode, the air guide area corresponding to the air guide angle of the lowest air guide plate 12 is located below the lowest grille 132. This can avoid the lowest grille 132 from blocking the airflow, ensuring that the hot airflow can be fully discharged downwards, gradually rise after approaching the ground, form a uniform temperature field, and improve heating comfort.

[0046] In some embodiments, in heating mode, when the air guide plate 12 rotates downward to the maximum angle d, pointing from the air inlet side to the air outlet side, the minimum distance between the end of the air guide plate 12 closest to the main frame 131 and the surface of the main frame 131 away from the air guide plate 12 includes 8.8mm, ensuring that there is a reasonable gap between the air guide plate 12 and the main frame 131 at the maximum downward angle, avoiding motion interference, and ensuring the safe and reliable operation of the structure.

[0047] Alternatively, in one possible real-time mode of this application, such as Figure 6-7 As shown, in heating mode, when the air guide plate 12 is rotated downward to the maximum downward angle, the grille 132 below the air guide plate 12 is located on the extension line of the air guide plate 12.

[0048] In this embodiment, in the vertical direction, the corresponding air guide plate 12 is located above the corresponding grille 132. For example, the lowermost air guide plate 12 is located above the lowermost grille 132, and the uppermost air guide plate 12 is located above the uppermost grille 132. In heating mode, when the air guide plate 12 rotates downward to its maximum downward angle, the corresponding grille 132 is located on the extension line of the corresponding air guide plate 12. For example, the lowermost grille 132 is located on the extension line of the lowermost air guide plate 12. This avoids the grille 132 obstructing the airflow from the air guide plate 12, thereby increasing the airflow volume and speed, and improving the efficiency of hot air delivery.

[0049] Based on the same inventive concept, this application provides a duct air conditioner, which includes an air outlet component as described in any of the above embodiments and a duct air conditioner body.

[0050] It should be noted that since the duct air conditioner of this application embodiment includes the air outlet component of this application embodiment, the duct air conditioner of this application embodiment also has the above-mentioned beneficial effects of the air outlet component of this application embodiment, which will not be repeated here.

[0051] By applying the embodiments of this application, at least the following beneficial effects can be achieved: 1. In the air outlet assembly provided in this application embodiment, the top wall 111 of the air outlet panel 11 includes a first guide surface 1111, a second guide surface 1112, and a third guide surface 1113 connected sequentially from the air inlet side to the air outlet side. The second guide surface 1112 is inclined upward at an angle α of 30° to 60°. The bottom wall 112 includes a fourth guide surface 1121, a fifth guide surface 1122, and a sixth guide surface 1123 connected sequentially from the air inlet side to the air outlet side. The sixth guide surface 1123 is inclined downward at an angle b of 30° to 60°. Thus, the size of the air outlet channel in the vertical direction gradually increases from the air inlet side to the air outlet side, enabling the airflow to gradually diffuse. The guide surfaces are level with each other. The smooth transition prevents airflow separation and maintains airflow uniformity. The air guide plate 12 is rotatably mounted inside the air outlet panel 11 and close to the air outlet side. In cooling mode, the air guide plate 12 rotates upward to deflect the airflow. Combined with the tilt angle design of the second air guide surface 1112, it can guide the airflow on the air outlet side to travel along the ceiling, improving cooling efficiency. In heating mode, the air guide plate 12 rotates downward to deflect the airflow. Combined with the tilt angle design of the sixth air guide surface 1123, it can guide the airflow on the air outlet side to travel along the ground, improving heating efficiency. It achieves the dual effects of long-distance air delivery and uniform diffusion, and can also reduce turbulence and wind resistance, thereby improving the air guiding and control effects.
