[0049] With reference to Figures 1 to 3 The utility model provides a kind of air conditioner, comprising:

[0050] Casing 200, the air duct 210 is formed in the casing 200, the air outlet is also provided on the casing 200 and communicated with the air duct 210, the air outlet extends along the up-down direction of the casing 200;And

[0051] Air outlet grille 300, the air outlet grille 300 is installed at the air outlet, the air outlet grille 300 includes multiple groups of vertical ribs arranged along its width direction, the air outlet grille 300 includes first air outlet area 310, second air outlet area 320 and third air outlet area 330, the second air outlet area 320 and the third air outlet area 330 are located at the two sides of the first air outlet area 310 respectively, the multiple groups of vertical ribs include first group of vertical ribs, second group of vertical ribs and third group of vertical ribs, the first group of vertical ribs, the second group of vertical ribs and the third group of vertical ribs are arranged in the first air outlet area 310, second air outlet area 320 and third air outlet area 330 respectively;The air outlet grille 300 is provided with a gilding layer, and the gilding layer is at least provided on the side of the air outlet grille 300 outward.

[0052] The technical scheme of the utility model reduces the abrasion of air conditioner in the process of daily use or carrying, and further reduces the local thinning of air outlet grille 300, and further reduces the risk of fracture of air outlet grille 300, and further improves the service life of air outlet grille 300. Meanwhile, by setting gilding layer on at least the side of air outlet grille 300 outward, the air conditioner is more beautiful, and the grade of air conditioner is improved. It should be noted that the gilding layer can be only provided on the side of air outlet grille 300 outward, and the gilding layer can also wrap and cover the entire air outlet grille 300.

[0053] The process flow of setting gilding layer on air outlet grille 300 is that: first, the surface of air outlet grille 300 is treated by plasma surface treatment to increase the adhesion of the surface of air outlet grille 300, then the air outlet grille 300 of first air outlet area 310 is treated by gilding along the first direction, then the air outlet grille 300 of second air outlet area 320 is treated by gilding along the opposite direction of the first direction, and finally the air outlet grille 300 of third air outlet area 330 is treated by gilding along the first direction, wherein the first direction is the length direction of air outlet grille 300.

[0054] Specifically, the thickness of the gold stamping layer is t, 0.02mm≤t≤0.04mm. Understandably, if t<0.02mm, the gold stamping layer will be too thin, which will still be easy to be worn or scratched during use, and thus will also easily cause the problem of the air outlet grille 300 breaking; and if t>0.04mm, the air outlet grille 300 will be easy to produce light reflection under the irradiation of light or sunlight, which will affect the daily use of the user, and meanwhile, the gold stamping layer being too thick will also cause the plating layer to be uneven or not firm, and thus will reduce the yield. Therefore, by reasonably setting the thickness of the gold stamping layer, the processing of the gold stamping layer is facilitated, the yield of the gold stamping layer is improved, the wear resistance of the air outlet grille 300 is improved, the risk of the air outlet grille 300 breaking is reduced, and the service life of the air outlet grille 300 is improved.

[0055] Specifically, the gold stamping layer comprises a PET layer, a protective layer, a metal layer and a glue layer arranged in sequence, the glue layer is used for pasting and fixing the gold stamping layer to the surface of the air outlet grille 300, the glue layer can adopt any one of hot melt glue, EVA glue, PUR reactive polyurethane glue, pressure sensitive adhesive, high temperature resistant modified acrylic glue, etc., the metal layer can adopt any one of titanium, titanium gold, vacuum aluminum plating, copper (Cu) plating, imitation gold alloy, silver, gold, etc., the protective layer is used for protecting the metal layer from physical damage during daily wiping, dust friction or installation process, and meanwhile, the final visual effect is controlled through a matte or bright coating, i.e. the reflection of light is reduced. The PET layer provides mechanical strength and flexibility, facilitates subsequent processing, ensures uniform adhesion of the subsequent plating layer, and avoids uneven reflection of the metal layer due to uneven substrate.

[0056] Further, in an embodiment, the gold stamping layer is arranged at least on the outward side of the vertical rib 400, thereby increasing the wear resistance of the surface of the vertical rib 400, thereby reducing the local thinning of the vertical rib 400, thereby reducing the risk of the vertical rib 400 breaking, and thereby improving the service life of the vertical rib 400. Of course, in other embodiments, the gold stamping layer can wrap the entire vertical rib 400.

[0057] Further, the gold stamping layer is arranged at the chamfered corner of the outward side of the vertical rib 400. Understandably, the chamfered corner of the outward side of the vertical rib 400 is also easy to be worn during daily use, and therefore, by further arranging the gold stamping layer at the chamfered corner of the vertical rib 400, the wear of the chamfered corner of the vertical rib 400 during daily carrying and use is avoided, thereby improving the wear resistance of the chamfered corner of the vertical rib 400, thereby reducing the risk of the vertical rib 400 breaking, and thereby improving the service life of the vertical rib 400.

[0058] In an embodiment, the width of the gilding layer corresponding to a single vertical rib 400 is greater than the width of the inward side of the vertical rib 400. Understandably, the gilding layer on the outward side is directly exposed to sunlight and the external environment, and a wider gilding layer can completely cover the exposed surface of the vertical rib 400, preventing the substrate from yellowing or embrittlement due to ultraviolet radiation, thereby prolonging the service life of the vertical rib 400.

[0059] Specifically, the length of the gilding layer corresponding to a single vertical rib 400 is a1, 1200mm≤a1≤1400mm, so that the gilding layer can cover the entire vertical rib 400 in the length direction, thereby avoiding the outward side of the vertical rib 400 being directly exposed to the outside, thereby improving the wear resistance of the vertical rib 400, reducing the risk of the vertical rib 400 breaking, prolonging the service life of the vertical rib 400, and improving the aesthetics of the air outlet grille 300.

[0060] Further, the width of the gilding layer corresponding to a single vertical rib 400 is w1, 3mm≤w1≤4mm. Thus, the gilding layer can cover the entire vertical rib 400 in the width direction, thereby avoiding the outward side of the vertical rib 400 being directly exposed to the outside, thereby improving the wear resistance of the vertical rib 400, reducing the risk of the vertical rib 400 breaking, prolonging the service life of the vertical rib 400, and improving the aesthetics of the air outlet grille 300.

[0061] In an embodiment, the air outlet grille 300 further comprises two air guide ribs 460, and the two air guide ribs 460 are respectively located on the two sides of the second air outlet area 320 and the third air outlet area 330 away from each other. The air guide rib 460 comprises a first air guide section 450 and a second air guide section 450 connected thereto. The two first air guide sections 450 extend along the front-rear direction of the cabinet 200, and the distance between the two second air guide sections 450 gradually increases away from the air outlet. By extending the first air guide section 450 in the front-rear direction, i.e., the distance between the two first air guide sections 450 remains unchanged, thereby optimizing the air flow of the air outlet grille 300, making the air outlet grille 300 air outlet more uniform, while also reducing the resistance area between the air flow blown out of the air outlet and the first air guide section 450, reducing the air outlet resistance, thereby improving the air supply distance, while also reducing the noise generated between the air flow and the first air guide section 450, thereby improving the user experience. The distance between the two second air guide sections 450 gradually increases away from the air outlet, i.e., the second air guide section 450 is flared, thereby increasing the air supply area of the air outlet grille 300, thereby further improving the user experience.

[0062] Specifically, the two air guide ribs 460 are provided with the gold plating layer on the side facing away from each other. It can be understood that the side of the air guide ribs 460 facing away from each other is located on both sides of the air outlet grille 300, so that the two air guide ribs 460 are more likely to be contacted during the daily handling and use of the air outlet grille 300, or during the installation and disassembly of the air outlet grille 300. Therefore, by providing the gold plating layer on the two sides of the air guide ribs 460 facing away from each other, the wear resistance of the side of the air guide ribs 460 facing away from each other is improved, thereby reducing the risk of breakage of the air guide ribs 460, and thereby improving the service life of the air guide ribs 460 and the air outlet grille 300.

[0063] Specifically, the plurality of vertical ribs 400 are located on the same arc surface. Thus, the air flow of the air outlet grille 300 is optimized, so that the air flow blown out through the air outlet grille 300 is more uniform, thereby improving the air outlet effect of the air outlet grille 300; at the same time, the appearance of the air outlet grille 300 is also improved, thereby improving the user experience.

[0064] In an embodiment, the air outlet grille 300 is provided in plurality. Among them, the plurality of air outlet grilles 300 can be two distributed above and below, or three distributed above, middle and below, or two distributed on the left and right, or three distributed on the left, middle and right. In embodiment 1, the air outlet grille 300 is directly connected with the cabinet 200, and the adjacent two air outlet grilles 300 are abutted or spaced apart; in embodiment 2, the air outlet grille 300 is directly connected with the cabinet 200, and the adjacent two air outlet grilles 300 can also be directly connected; of course, at least one air outlet grille 300 can be connected with the cabinet 200, and the other air outlet grilles 300 can be connected with this air outlet grille 300. Of course, in other embodiments, the plurality of air outlet grilles 300 can be provided in 3x3, which will not be listed one by one here.

[0065] Specifically, the air outlet grille 300 further comprises an upper edge plate 470 and a lower edge plate 480, both ends of the vertical rib 400 in the length direction are connected to the upper edge plate 470 and the lower edge plate 480 respectively, and the vertical rib 400 protrudes from the upper edge plate 470 and the lower edge plate 480 in the front-rear direction of the cabinet 200. The distance between the vertical rib 400 and the upper edge plate 470 and / or the lower edge plate 480 in the front-rear direction of the cabinet 200 is c1, and c1≥1mm. Thus, when the gold plating layer is provided on the side of the vertical rib 400 facing outward, the gold plating layer will not be plated on the upper edge plate 470 and the lower edge plate 480, thereby reducing the process difficulty of providing the gold plating layer on the vertical rib 400, and thereby improving the production and processing efficiency of the vertical rib 400.

[0066] Specifically, the length of the air outlet grille 300 is a2, and 1200mm≤a2≤1600mm, and the width of the air outlet grille 300 is w2, and 200mm≤w2≤280mm. By reasonably setting the length and width of the air outlet grille 300, the air outlet area of the air outlet grille 300 is reasonably increased, the air volume and air speed are balanced, the airflow is evenly diffused, the user's body comfort is improved, and the reasonable length and width of the air outlet grille 300 also improve the appearance of the air outlet grille 300, thereby improving the user's use experience. If the air outlet grille 300 is too long, the airflow passing through the narrow gap is prone to high-frequency whistling; if the air outlet grille 300 is too wide, the air outlet grille 300 may vibrate abnormally due to insufficient support.

[0067] Referring to Figure 3 and Figure 4 In an embodiment, the air outlet grille 300 further comprises a transverse rib 500 connected to the vertical rib 400. By providing the transverse rib 500, the stability of the vertical rib 400 is improved, and the deformation amount of the vertical rib 400 during air outlet is reduced, thereby improving the strength and stability of the air outlet grille 300.

[0068] Specifically, the outward side of the vertical rib 400 protrudes from the transverse rib 500, and the distance between the outward side of the vertical rib 400 and the outward side of the transverse rib 500 in the front-rear direction of the cabinet 200 is c2, and c2≥2mm. Therefore, when a gold stamping layer is provided on the outward side of the vertical rib 400, the gold stamping layer will not be stamped on the transverse rib 500, thereby reducing the process difficulty of providing the gold stamping layer on the vertical rib 400, and thereby improving the production and processing efficiency of the vertical rib 400.

[0069] Further, in an embodiment, the gold stamping layer is provided at least on the outward side of the transverse rib 500, thereby increasing the wear resistance of the surface of the transverse rib 500, thereby reducing the risk of fracture of the transverse rib 500, thereby improving the service life of the transverse rib 500. Of course, in other embodiments, the gold stamping layer can wrap the entire transverse rib 500.

[0070] Specifically, the transverse rib 500 is provided in multiple along the length direction of the air outlet grille 300, and the interval between two adjacent transverse ribs 500 is d1, and 40mm≤d1≤90mm. The transverse rib 500 with an interval of 60mm to 80mm further improves the strength of the air outlet grille 300, thereby further reducing the deformation amount of the vertical rib 400 during air outlet.

[0071] In an embodiment, the vertical ribs 400 include a main section 440 connected to the horizontal ribs 500 and a wind guide section 450 connected to the main section 440 on a side of the main section 440 facing the air outlet. The wind guide section 450 gradually decreases in width in a direction close to the air outlet. By arranging the wind guide section 450, the resistance of the air blown out by the air outlet to flow through the vertical ribs 400 is reduced, thereby reducing the air outlet resistance of the air outlet grille 300, improving the air supply efficiency of the air outlet grille 300, reducing the noise of the air outlet grille 300, and improving the comfort of the user.

[0072] Specifically, the first group of vertical ribs includes a plurality of first vertical ribs 410, the second air outlet area 320 and the third air outlet area 330 each include a first expansion area 340 and a second expansion area 350, respectively, the second group of vertical ribs and the third group of vertical ribs each include a plurality of second vertical ribs 420 and a plurality of third vertical ribs 430, respectively, the second vertical ribs 420 and the third vertical ribs 430 are arranged in the first expansion area 340 and the second expansion area 350, respectively, the first vertical ribs 410 extend in the front-rear direction of the cabinet 200, and the angle between the third vertical ribs 430 and the first vertical ribs 410 is greater than the angle between the second vertical ribs 420 and the first vertical ribs 410. Therefore, the first vertical ribs 410 are arranged to extend in the front-rear direction of the cabinet 200, so that the air blown out by the air outlet is directly blown out. Further, the second vertical ribs 420 and the third vertical ribs 430 are arranged to be inclined relative to the straight first vertical ribs 410, thereby increasing the air outlet area of the air outlet grille 300, and compared with the prior art in which all vertical ribs 400 extend in the front-rear direction, the second vertical ribs 420 and the third vertical ribs 430 are arranged to be inclined in the present application, thereby reducing the air outlet resistance of the expansion area of the air outlet grille 300, thereby reducing the noise of the air outlet grille 300, thereby improving the air outlet efficiency and the comfort of the user.

[0073] In an embodiment, the air outlet grille 300 is arranged in an arc shape. The arc-shaped air outlet grille 300 looks more beautiful as a whole, which can improve the grade and quality of the building. Meanwhile, under high-speed wind pressure, the wind load on the arc-shaped grille is more uniform, which can effectively reduce the deformation and vibration of the grille. Of course, in another embodiment, the air outlet grille 300 can also be arranged in a planar shape. The planar air outlet grille 300 can ensure that the airflow is more uniform when passing through, thereby improving the air supply efficiency of the air conditioner. Meanwhile, the planar air outlet grille 300 is relatively simple to install, does not need complex adjustment and positioning, and can save installation time and cost.

[0074] The material of the air outlet grille 300 is ABS or PC or other high-temperature-resistant material. The air conditioner can perform cooling and heating. Therefore, the air outlet grille 300 may be subjected to high-temperature air flow. Therefore, such high-temperature-resistant material is used to reduce the odor or deformation of the air outlet grille 300 under high-temperature conditions, thereby improving the stability of the air outlet grille 300 and the comfort of the user.

[0075] Specifically, the angle between the first vertical rib 410 and the front-rear direction of the cabinet 200 is θ1, and 0°≤θ1≤3°. Understandably, there will be certain errors in the production and installation of the air outlet grille 300. Therefore, the first vertical rib 410 cannot be completely consistent with the front-rear direction of the cabinet 200. Therefore, 0°≤θ1≤3° reduces the production and processing precision of the air outlet grille 300, reduces the installation difficulty of the air outlet grille 300, and further reduces the production and manufacturing cost of the air outlet grille 300 and the air conditioner.

[0076] Specifically, the angle between the second vertical rib 420 and the front-rear direction of the cabinet 200 is θ2, and the angle between the third vertical rib 430 and the front-rear direction of the cabinet 200 is θ3, 15°≤θ2≤25°, and 35°≤θ3≤45°. The angle between the second vertical rib 420 and the front-rear direction of the cabinet 200 is between 15° and 25°, and the angle between the third vertical rib 430 and the front-rear direction of the cabinet 200 is between 35° and 45°. Therefore, while increasing the air outlet area of the first and second expansion regions 340 and 350, the turbulent flow and vortex flow generated when the air flow passes through the grille are further reduced, thereby reducing the air outlet resistance of the air outlet grille 300, further reducing the noise of the air outlet grille 300, and further improving the air outlet efficiency and the comfort of the user.

[0077] Preferably, the span of the vertical rib 400 along the front-rear direction of the cabinet 200 gradually decreases from the middle of the air outlet grille 300 to both sides of the air outlet grille 300 in the width direction. Since the vertical rib 400 on both sides of the air outlet grille 300 has a certain angle with the front-rear direction of the cabinet 200, i.e., the vertical rib 400 on both sides of the air outlet grille 300 has a certain angle with the air outlet direction of the air outlet, the span of the vertical rib 400 on both sides of the air outlet grille 300 along the front-rear direction of the cabinet 200 is reduced, thereby reducing the projection of the vertical rib 400 on both sides of the air outlet grille 300 in the air outlet direction, i.e., reducing the air outlet resistance, further reducing the noise of the air outlet grille 300, and further improving the air outlet efficiency and the comfort of the user.

[0078] Reference Figures 4 to 6Specifically, the maximum span of the first vertical rib 410 along the front-rear direction of the cabinet 200 is b1, and 10mm≤b1≤11mm. The vertical rib 400 with the maximum span is located at the straight guide area of the air outlet grille 300, and the size range of 10mm to 11mm is large, thereby reducing the machining precision of the air outlet grille 300, and further reducing the production manufacturing cost of the air outlet grille 300.

[0079] Specifically, the minimum span of the third vertical rib 430 along the front-rear direction of the cabinet 200 is b2, and 6mm≤b2≤7mm. The vertical rib 400 with the minimum span is located at the second expansion guide area 350, and the size range of 6mm to 7mm is large, thereby reducing the machining precision of the air outlet grille 300, and further reducing the production manufacturing cost of the air outlet grille 300.

[0080] Further, the plurality of vertical ribs 400 are arranged at intervals along the width direction of the air outlet grille 300, and the interval between two adjacent vertical ribs 400 is d2, and 5mm≤d2≤7mm, thereby increasing the air guiding effect of the vertical rib 400, increasing the air outlet area of the air outlet grille 300, and further 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.

[0081] With reference to Figure 7 Specifically, the length of the air outlet along the length direction of the cabinet 200 is a3, the length of the air outlet grille 300 along the length direction of the cabinet 200 is a2, and a2>a3. The longer air outlet grille 300 may be more visually attractive, especially in areas with a large space area, which can increase the overall decoration effect and better integrate with the indoor decoration style, thereby enhancing the overall aesthetics of the indoor environment. When the length of the air outlet grille 300 is greater than that of the air outlet, the air exchange area is correspondingly increased, which is beneficial to more quickly complete the air exchange between indoor and outdoor, and improve the indoor air quality. Further, the longer air outlet grille 300 may be helpful to uniformly distribute airflow in a larger range, which can change the wind direction and wind speed, reduce vortex and dead angle, and improve the efficiency of the air conditioning system.
