[0032] Reference Figures 1 to 3 The present invention provides an air conditioner, comprising:

[0033] A housing 10 having an air duct 11 formed therein and an air outlet connected to the air duct 11, the air outlet extending in a vertical direction of the housing 10; and

[0034] The air outlet grille 20 is installed at the air outlet, and the air outlet grille 20 includes a plurality of vertical ribs 21 spaced apart along its width direction. The air outlet grille 20 includes a straight lead area 231, two first expansion lead areas 232 and two second expansion lead areas 233. The two first expansion lead areas 232 are respectively located on both sides of the straight lead area 231, and the two second expansion lead areas 233 are respectively located on the side of the corresponding first expansion lead area 232 away from the straight lead area 231. The vertical ribs 21 include a first vertical The rib 21a, the second vertical rib 21b and the third vertical rib 21c, the first vertical rib 21a, the second vertical rib 21b and the third vertical rib 21c are respectively arranged in the straight lead area 231, the first expansion lead area 232 and the second expansion lead area 233, the first vertical rib 21a extends along the front and rear directions of the casing 10, and the angle between the third vertical rib 21c and the first vertical rib 21a is greater than the angle between the second vertical rib 21b and the first vertical rib 21a.

[0035] The air conditioner in the technical solution of the present invention includes a casing 10 and an air outlet grille 20. An air duct 11 is formed in the casing 10. An air outlet connected to the air duct 11 is also provided on the casing 10. The air outlet extends in the up and down directions of the casing 10. The air outlet grille 20 is installed at the air outlet. The air outlet grille 20 includes a plurality of vertical ribs 21 spaced apart along its width direction. The air outlet grille 21 includes a straight lead area 231, two first expansion lead areas 232 and two second expansion lead areas. The lead-in area 233, the two first expanded lead-in areas 232 are respectively located on both sides of the straight lead-in area 231, and the two second expanded lead-in areas 233 are respectively located on the side of the corresponding first expanded lead-in area 232 away from the straight lead-in area 231. The vertical ribs 21 include the first vertical ribs 21a, the second vertical ribs 21b and the third vertical ribs 21c. The first vertical ribs 21a, the second vertical ribs 21b and the third vertical ribs 21c are respectively arranged in sequence on the straight lead-in area 231, the first expanded lead-in area 232 and the second expanded lead-in area 233. 232 and the second expansion area 233, the first vertical rib 21a extends along the front-to-back direction of the casing 10, and the angle between the third vertical rib 21c and the first vertical rib 21a is greater than the angle between the second vertical rib 21b and the first vertical rib 21a; therefore, the first vertical rib 21a is extended along the front-to-back direction of the casing 10, so that the wind blown out of the air outlet is blown out directly, and further, the second vertical rib 21b and the third vertical rib 21c are tilted relative to the first vertical rib 21a, thereby increasing the air outlet area of ​​the air outlet grille 20 on the one hand, and compared with the technical scheme in the prior art that all vertical ribs 20 extend along the front-to-back direction, the second vertical rib 21b and the third vertical rib 21c in the technical scheme of the present application are tilted to reduce the air outlet resistance in the expansion area of ​​the air outlet grille 20, thereby reducing the noise of the air outlet grille 20, and thereby improving the air outlet efficiency and user comfort.

[0036] In one embodiment, the air outlet grille 20 is curved. This curved air outlet grille 20 enhances the overall aesthetics and enhances the building's class and style. Furthermore, under high-speed wind pressure, the curved grille experiences a more uniform wind load, effectively reducing deformation and vibration. Of course, in another embodiment, the air outlet grille 20 can also be flat. A flat air outlet grille 20 ensures a more uniform airflow, preventing localized overly strong or weak airflow, thereby improving the air supply efficiency of the air conditioner. Furthermore, the flat air outlet grille 20 is relatively simple to install, requiring no complex adjustment or positioning, thus saving installation time and costs.

[0037] Among them, the material of the air outlet grille 20 is a material with high heat resistance such as ABS or PC. The air conditioner can perform cooling and heating. Therefore, the air outlet grille 20 may experience high-temperature wind flow. Therefore, the use of this type of high-temperature resistant material reduces the odor or deformation of the air outlet grille 20 under high temperature conditions, thereby improving the stability of the air outlet grille 20 and improving the user's comfort.

[0038] Specifically, the angle between the first vertical rib 21a and the front-to-back direction of the casing 10 is α1, 0°≤α1≤3°. It can be understood that there will inevitably be certain errors in the production, processing and installation of the air outlet grille 20. Therefore, the first vertical rib 21a and the front-to-back direction of the casing 10 cannot be completely consistent. Therefore, 0°≤α1≤3° reduces the production and processing accuracy of the air outlet grille 20, reduces the installation difficulty of the air outlet grille 20, and thereby reduces the production and manufacturing costs of the air outlet grille 20 and the air conditioner.

[0039] Specifically, the angle between the second vertical rib 21b and the front-to-back direction of the housing 10 is α2, and the angle between the third vertical rib 21c and the front-to-back direction of the housing 10 is α3, with 15°≤α2≤25°, and 35°≤α3≤45°. The angle between the second vertical rib 21b and the front-to-back direction of the housing 10 is between 15° and 25°, and the angle between the third vertical rib 21c and the front-to-back direction of the housing 10 is between 35° and 45°. This increases the air outlet area of ​​the first expansion zone 232 and the second expansion zone 233 while further reducing the turbulence and eddies generated when the airflow passes through the grille, thereby reducing the air outlet resistance of the air outlet grille 20, thereby reducing the noise of the air outlet grille 20, and thereby improving air outlet efficiency and user comfort.

[0040] Preferably, the span of the vertical ribs 21 along the front-to-back direction of the casing 10 is gradually reduced from the middle of the air outlet grille 20 toward the two sides in the width direction of the air outlet grille 20. Since the vertical ribs 21 on both sides of the air outlet grille 20 have a certain angle with the front-to-back direction of the casing 10, that is, the vertical ribs 21 on both sides of the air outlet grille 20 have a certain angle with the air outlet direction of the air outlet, the span of the vertical ribs 21 on both sides of the air outlet grille 20 along the front-to-back direction of the casing 10 is reduced, thereby reducing the projection of the vertical ribs 21 on both sides of the air outlet grille 20 in the air outlet direction of the air outlet, that is, reducing the air outlet resistance, thereby reducing the noise of the air outlet grille 20, and thereby improving the air outlet efficiency and user comfort.

[0041] Reference Figures 4 to 6Specifically, the maximum span of the first vertical rib 21a along the front-to-back direction of the housing 10 is H1, with a value of 10 mm ≤ H1 ≤ 11 mm. The vertical rib 21 with the largest span is located in the straight-in area 231 of the air outlet grille 20. The wide range of 10 mm to 11 mm reduces the machining accuracy of the air outlet grille 20 and, in turn, the manufacturing cost of the air outlet grille 20.

[0042] Specifically, the minimum span of the third vertical rib 21c along the front-to-back direction of the housing 10 is H2, with a range of 6 mm ≤ H2 ≤ 7 mm. The vertical rib 21 with the minimum span is located in the second expansion region 233, and the larger span range of 6 mm to 7 mm reduces the machining accuracy of the air outlet grille 20, thereby reducing the manufacturing cost of the air outlet grille 20.

[0043] Furthermore, the plurality of vertical ribs 21 are spaced apart along the width direction of the air outlet grille 20, and the interval between two adjacent vertical ribs 21 is s1, 5mm≤s1≤7mm, thereby increasing the air guiding effect of the vertical ribs 21 and the air outlet area of ​​the air outlet grille 20, thereby improving the air supply efficiency of the air conditioner and the user experience, and also reducing the possibility of external debris entering the interior of the air conditioner.

[0044] Reference Figure 7 In one embodiment, the air outlet grille 20 further includes transverse ribs 22, which are connected to the vertical ribs 21. By providing the transverse ribs 22, the stability of the vertical ribs 21 is improved, and the deformation of the vertical ribs 21 during the air outlet process is reduced, thereby improving the strength and stability of the air outlet grille 20.

[0045] Specifically, multiple transverse ribs 22 are spaced apart along the length of the air outlet grille 20, with the spacing between adjacent transverse ribs 22 being s2, where 60 mm ≤ s2 ≤ 80 mm. The 60 to 80 mm spacing of the transverse ribs 22 further enhances the strength of the air outlet grille 20, thereby further reducing the deformation of the vertical ribs 21 during airflow.

[0046] In one embodiment, the vertical ribs 21 include a main section 211 and an air guide section 212. The main section 211 is connected to the transverse ribs 22, and the air guide section 212 is connected to the side of the main section 211 facing the air outlet. The width of the air guide section 212 gradually decreases as it approaches the air outlet. The provision of the air guide section 212 reduces the resistance of the air flowing out of the air outlet through the vertical ribs 21, thereby reducing the airflow resistance of the air outlet grille 20, improving the air supply efficiency of the air outlet grille 20, reducing the noise level of the air outlet grille 20, and improving user comfort.

[0047] Reference Figure 1 Specifically, the length of the air outlet along the length direction of the casing 10 is L1, and the length of the air outlet grille 20 along the length direction of the casing 10 is L2, and L2>L1. A longer air outlet grille 20 may be more visually attractive, especially in areas with a larger spatial area, which can increase the overall decorative effect and better integrate with the interior decoration style, thereby enhancing the overall aesthetics of the indoor environment. When the length of the air outlet grille 20 is greater than the air outlet, the air exchange area increases accordingly, which is conducive to faster indoor and outdoor air exchange and improved indoor air quality. Furthermore, a longer air outlet grille 20 may help to evenly distribute airflow over a larger range. It can improve the efficiency of the air-conditioning system by changing the wind direction and wind speed, reducing vortices and dead corners.
