[0011] In some embodiments, the grille body is an integrally formed part and further includes horizontal grille bars, there are multiple horizontal grille bars and they are spaced apart along the length direction of the air outlet grille. The horizontal grille bars intersect with the vertical grille bars to form grille holes between the vertical grille bars and the horizontal grille bars. The outer surface of the vertical grille bars protrudes outward relative to the outer surface of the horizontal grille bars.

[0012] In some embodiments, each of the horizontal bars extends along the width direction of the air outlet grille, the distance between two adjacent horizontal bars along the length direction of the air outlet grille is greater than the distance between two adjacent vertical bars along the width direction of the air outlet grille, and at least a portion of the inner surface of at least one horizontal bar protrudes inward relative to the inner surface of the vertical bar.

[0013] In some embodiments, the dimension of the horizontal grille along its own airflow direction is the width of the horizontal grille, at least one of the horizontal grilles is a narrow grille, at least one of the horizontal grilles is a wide grille, the maximum width of the wide grille is greater than the maximum width of the narrow grille, and the wide grille and the narrow grille are alternately arranged along the length direction of the air outlet grille; and / or, at least one of the vertical grilles is a widened grille, and the widened grille widens inward at the junction with the horizontal grille.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0023] Reference Figure 1 and Figure 2 The air conditioner 100 includes an air outlet grille 10 for discharging air from the air conditioner 100. Along the airflow direction of the air outlet grille 10, there are inner and outer sides, respectively. The air outlet grille 10 includes a grille body 10a and a decorative layer 10b. The inner side is the upstream side in the airflow direction of the air outlet grille 10, and the outer side is the downstream side. Because the decorative layer is relatively thin, it is shown in the accompanying drawings as overlapping with the outer surface of the grille body 10a.

[0024] The decorative layer 10b can be a layered structure with certain functions and / or decorations disposed on the outer surface of the grille body 10a. The material of the decorative layer 10b is not limited. For example, the material of the decorative layer 10b can be plastic, metal, etc. For example, the decorative layer 10b can be disposed on the outer surface of the grille body 10a. For example, the decorative layer 10b can be combined with the outer surface of the grille body 10a by means of spraying, electroplating, vapor deposition, pasting, bonding, hot pressing, magnetic attraction, hot foil stamping, screen printing, offset printing, etc.

[0025] Of course, the decorative layer 10b can be a single layer structure or a composite layer structure. The decorative layer 10b can be set to different colors, textures or patterns on the air outlet grille 10, achieving a multi-layered visual effect and making the overall appearance of the air conditioner 100 more beautiful. In addition, by selecting materials for the decorative layer 10b, the weather resistance (such as resistance to ultraviolet rays and temperature difference) and corrosion resistance of the outer surface of the air outlet grille 10 can be enhanced.

[0026] The grille body 10a includes longitudinal grille bars 1. The longitudinal grille bars 1 extend along the length direction F2 of the air outlet grille 10. There are multiple longitudinal grille bars 1 and they are spaced apart along the width direction F1 of the air outlet grille 10. The decorative layer 10b is disposed on the outer surface 1c of the longitudinal grille bars 1. The extension direction of the longitudinal grille bars 1 from the inside to the outside is the air guiding direction. The air guiding directions of any two longitudinal grille bars 1 are parallel.

[0027] The structural dimensions of the longitudinal grid strip 1 are not limited. For example, the width, thickness, air guide length, and spacing between the longitudinal grid strips 1 can all be designed according to the air volume requirements and structural space of the air conditioner 100 to achieve the goals of optimizing the uniform distribution of airflow and reducing wind resistance.

[0028] The longitudinal grating 1 extends along the length direction F2 of the air outlet grille 10. That is, the longitudinal grating 1 is the main grating of the air outlet grille 10. The decorative layer 10b is placed on the outer surface 1c of the longitudinal grating 1, which makes the overall visual shape of the air outlet grille 10 more prominent, thereby enhancing the sense of vertical visual extension and strengthening the vertical stretching visual effect of the space.

[0029] The airflow direction of any two longitudinal grilles 1 is parallel, meaning that the airflow direction of all longitudinal grilles 1 is consistent. This simplifies the structure of the air outlet grille 10, facilitating its production and reducing manufacturing costs and complexity. It also provides convenience for subsequent assembly and maintenance. Furthermore, the consistent airflow direction of the longitudinal grilles 1 allows the air outlet grille 10 to create a more regular and uniform airflow direction, reducing airflow turbulence and dispersion, and improving the concentration and directionality of the airflow. This effectively guides the airflow to a farther area, increasing the air delivery distance of the air conditioner 100.

[0030] In the above technical solution, by making the air guiding direction of the longitudinal grid strips 1 consistent and extending along the length of the air outlet grille 10, not only is the structure of the air outlet grille 10 simpler and easier to manufacture, reducing production costs and difficulty, but also the airflow organization is optimized, reducing airflow turbulence and dispersion, improving the concentration and directionality of the air outlet, thereby increasing the air delivery distance of the air conditioner 100.

[0031] For example, the air outlet grille 10 remains fixed whether the air conditioner 100 is turned on or off. By providing a decorative layer 10b on the air outlet grille 10, the appearance of the air conditioner 100 can be improved. However, this application is not limited to this. In other embodiments of this application, the air outlet grille 10 can also be made movable, which will not be elaborated here.

[0032] refer to Figure 2 In some embodiments, two adjacent vertical gratings 1 form an adjacent grating group 1a. The distance between two vertical gratings 1 in an adjacent grating group 1a along the width direction F1 of the air outlet grille 10 is the grating spacing. In any two adjacent grating groups 1a, the grating spacing of the one closer to the center surface S1 of the air outlet grille 10 is less than or equal to the grating spacing of the one farther from the center surface S1 of the air outlet grille 10. The center surface S1 of the air outlet grille 10 refers to the plane located at the center position in the width direction F2 of the air outlet grille 10, which bisects the air outlet grille 10. It is worth noting that, except for the edge vertical gratings 1, each of the remaining vertical gratings 1 can form an adjacent grating group 1a with the vertical gratings 1 on both sides, that is, it can participate in the formation of two adjacent grating groups 1a.

[0033] For example, the arrangement of the longitudinal bars 1 can be based on the center plane S1 of the air outlet grille 10, with the spacing between adjacent longitudinal bars 1 gradually increasing towards both sides; or, the air outlet grille 10 can be divided into several bar setting areas, with the spacing between adjacent longitudinal bars 1 in each bar setting area being equal, and the spacing between bars in the bar setting areas closer to the two edges of the air outlet grille 10 being larger, thus forming a layout of longitudinal bars 1 that is dense in the middle and sparse on both sides. Of course, all longitudinal bars 1 can also be set at equal intervals along the width direction F1 of the air outlet grille 10.

[0034] For example, such as Figure 2 As shown, the air outlet grille 10 has a first adjacent grille bar group 1a1, a second adjacent grille bar group 1a2, and a third adjacent grille bar group 1a3 that are gradually moved away from the center surface S1 of the air outlet grille 10. The grille bar spacing L1 of the first adjacent grille bar group 1a1 is smaller than the grille bar spacing L2 of the second adjacent grille bar group 1a2, and the grille bar spacing L2 of the second adjacent grille bar group 1a2 is equal to the grille bar spacing L3 of the third adjacent grille bar group 1a3.

[0035] In the above technical solution, the spacing between the grilles is small in the area near the center surface S1, resulting in relatively greater resistance to airflow. Conversely, the spacing between the grilles is large in the area far from the center surface S1, allowing for smoother airflow and a relatively increased air volume. This achieves the effect of increasing the air volume on both sides and reducing direct airflow from the center surface S1, resulting in a more uniform and reasonable airflow distribution and improved air delivery comfort. Furthermore, a reasonable airflow distribution helps reduce noise generated by local turbulence when airflow passes through the grille, improving the quietness of the air conditioner 100.

[0036] refer to Figure 3 In some embodiments, all longitudinal grille bars 1 are equally spaced along the width direction F1 of the air outlet grille 10. For example, as... Figure 3 As shown, the air outlet grille 10 has a fourth adjacent grille bar group 1a4, a fifth adjacent grille bar group 1a5 and a sixth adjacent grille bar group 1a6 that are gradually moved away from the center surface S1 of the air outlet grille 10, wherein the grille bar spacing L4, L5 and L6 of the fourth adjacent grille bar group 1a4, the fifth adjacent grille bar group 1a5 and the sixth adjacent grille bar group 1a6 are all equal.

[0037] In the above design, all longitudinal gratings 1 are evenly spaced along the width direction F1 of the air outlet grille 10, which greatly simplifies mold design and manufacturing process. For example, the air outlet grille 10 is processed by injection molding, eliminating the need for complex dimensional adjustments and positioning operations for the longitudinal gratings 1 at different positions, thus improving production efficiency, reducing production costs, and ensuring product consistency and quality stability. Furthermore, the evenly spaced longitudinal gratings 1 allow for more uniform force distribution across the width of the air outlet grille 10, thereby enhancing the structural stability and reliability of the entire air outlet grille 10.

[0038] refer to Figure 3 In some embodiments, the length of the longitudinal grid strip 1 extending from the inside to the outside is the air guiding length. Among any two longitudinal grid strips 1, the air guiding length of the one that is relatively closer to the center surface S1 of the air outlet grille 10 is greater than or equal to the air guiding length of the one that is relatively farther away from the center surface S1 of the air outlet grille 10.

[0039] For example, the air guiding length of the longitudinal grid bars 1 can gradually decrease from the center surface S1 of the air outlet grille 10 to both sides. Alternatively, the air outlet grille 10 can be divided into several grid bar setting areas, with the air guiding length of the longitudinal grid bars 1 in each grid bar setting area being equal, and the air guiding length of the longitudinal grid bars 1 in the grid bar setting areas closer to the two side edges of the air outlet grille 10 being smaller, thus forming a layout with a longer air guiding length in the middle and shorter air guiding lengths on both sides. Of course, it is also possible that the air guiding length of all longitudinal grid bars 1 is equal.

[0040] For example, such as Figure 3As shown, the air outlet grille 10 has a first longitudinal grille 1a, a second longitudinal grille 1b, and a third longitudinal grille 1c that are gradually moved away from the center surface S1 of the air outlet grille 10. The air guiding length E1 of the first longitudinal grille 1a is greater than the air guiding length E2 of the second longitudinal grille 1b, and the air guiding length E2 of the second longitudinal grille 1b is equal to the air guiding length E3 of the third longitudinal grille 1c.

[0041] In the above design, the longitudinal bars 1 near the center surface S1 of the air outlet grille 10 have a longer guide length. This longer guide length means a longer connection and support between the longitudinal bars 1 and the surrounding structure, thus improving structural strength and the deformation resistance of the central longitudinal bars 1, thereby enhancing the overall structural reliability of the air outlet grille 10. Furthermore, when the guide length of the longitudinal bars 1 near the center surface S1 is greater than that of the longitudinal bars 1 farther from the center surface S1, the longer guide length of the longitudinal bars 1 near the center surface S1 can, to some extent, increase the airflow resistance in the middle area, directing more airflow to the sides, thereby increasing the airflow volume on both sides. This avoids direct airflow from the middle area causing discomfort, while ensuring sufficient airflow on both sides for temperature regulation.

[0042] refer to Figure 4 and Figure 5 In some embodiments, the air guiding lengths of any two longitudinal grilles 1 are equal. For example, as shown... Figure 4 As shown, the air outlet grille 10 is divided into a first grille setting area A1, a second grille setting area A2, and a third grille setting area A3. The first grille setting area A1 is located between the second grille setting area A2 and the third grille setting area A3. All longitudinal grille bars 1 have equal air guiding lengths, and the grille spacing of the longitudinal grille bars 1 in each grille setting area is equal. The grille spacing of the longitudinal grille bars 1 in the first grille setting area A1 is smaller than the grille spacing of the longitudinal grille bars 1 in the second grille setting area A2 and the third grille setting area A3. For example, as... Figure 5 As shown, the air guiding length of all longitudinal grid bars 1 is equal, and the spacing between all longitudinal grid bars 1 is equal.

[0043] In the above design scheme, the air guiding length of any two longitudinal grilles 1 is equal, which greatly simplifies the mold design and manufacturing process. For example, the air outlet grille 10 adopts the injection molding process, which eliminates the need to adjust the air guiding length for the longitudinal grilles 1 at different positions, improves production efficiency, reduces production costs, and also helps to ensure the consistency and quality stability of the air outlet grille 10, thereby reducing the scrap rate and saving production costs.

[0044] refer to Figure 5 In some embodiments, any two longitudinal grid strips 1 are identical. That is, all longitudinal grid strips 1 have the same structural dimensions, such as width, thickness, and air guide length, and the spacing, shape, and material between them are also the same.

[0045] In the above design, all longitudinal grilles 1 are identical, further enhancing the manufacturing convenience of the air outlet grille 10. This improves production efficiency, reduces production costs, and also helps ensure the consistency and quality stability of the air outlet grille 10. Simultaneously, the air outlet grille 10 helps create a smoother and more continuous airflow effect, reducing the generation of localized eddies or wind noise.

[0046] refer to Figure 5 In some embodiments, the decorative layer 10b is located on plane S2, with reference to... Figure 6 Alternatively, the decorative layer 10b may be located on a cylindrical surface S3 on which the axis extends along the length direction F2 of the air outlet grille 10.

[0047] In the above technical solution, when the decorative layer 10b is located on the plane S2, the structure of the air outlet grille 10 is relatively simple, which can reduce the manufacturing difficulty and facilitate the setting of the decorative layer 10b on the outer surface 1c of the longitudinal grille 1; the decorative layer 10b is located on the cylindrical surface S3 on which the axis extends along the length direction F2 of the air outlet grille 10, which can adapt to the arc appearance of the air conditioner 100, so that the air outlet grille 10 matches the curvature of the air conditioner 100 casing.

[0048] refer to Figure 7 and Figure 8 In some embodiments, the grille body 10a is a one-piece molded part and also includes horizontal grille bars 2. There are multiple horizontal grille bars 2, spaced F2 apart along the length direction F2 of the air outlet grille 10. The horizontal grille bars 2 intersect with the longitudinal grille bars 1 to form grille holes 1a between the longitudinal grille bars 1 and the horizontal grille bars 2. Figure 9 The outer surface 1c of the vertical grid bar 1 protrudes outward relative to the outer surface 2c of the horizontal grid bar 2.

[0049] The method of integral molding of the grille body 10a is not limited. For example, it can be injection molding, die casting, etc. For example, the air outlet grille 10 includes vertical grille bars 1 and horizontal grille bars 2. When the air outlet grille 10 is made of non-metallic material, the integral connection of the vertical grille bars 1 and horizontal grille bars 2 can be achieved by injection molding. For example, the vertical grille bars 1 and horizontal grille bars 2 can be integrally injection molded, or one can be processed first and then the other can be processed by embedding injection molding to achieve the integral connection of the vertical grille bars 1 and horizontal grille bars 2. The integral connection makes the overall structural strength of the air outlet grille 10 more stable and less prone to deformation.

[0050] In the above technical solution, the grille body 10a is manufactured by an integral molding process, making the entire air outlet grille 10 a continuous and complete structure, which is not prone to deformation and other problems, thus improving the overall structural strength and reliability of the air outlet grille 10. The outer surface 1c of the vertical grille 1 protrudes outward relative to the outer surface 2c of the horizontal grille 2. That is, the vertical grille 1 is closer to the user side, which makes it easier to process the decorative layer 10b only on the outer surface 1c of the vertical grille 1. This allows the overall visual shape of the air outlet grille 10 to be dominated by the vertical grille 1, thereby forming a sense of vertical visual extension and enhancing the vertical stretching visual effect of the space.

[0051] refer to Figures 8-9 In some embodiments, each horizontal slat 2 extends along the width direction F1 of the air outlet grille 10, and the distance M2 between two adjacent horizontal slats 2 along the length direction F2 of the air outlet grille 10 is greater than the distance M1 between two adjacent vertical slats 1 along the width direction F1 of the air outlet grille 10. Figure 7 At least a portion of the inner surface 2d of at least one horizontal grid bar 2 protrudes inward relative to the inner surface 1d of the vertical grid bar 1.

[0052] In the above technical solution, the distance M2 between two adjacent horizontal grilles 2 along the length direction F2 of the air outlet grille 10 is greater than the distance M1 between two adjacent vertical grilles 1 along the width direction F1 of the air outlet grille 10. That is, the horizontal grilles 2 are arranged more sparsely and the vertical grilles 1 are arranged more densely. In addition, the length direction of the vertical grilles 1 extends along the length direction F2 of the air outlet grille 10. As a result, the user will first notice the vertical grilles 1 extending along the length direction F2 of the air outlet grille 10, so that the overall visual shape of the air outlet grille 10 can be dominated by the vertical grilles 1. At least a portion of the inner surface 2d of the horizontal grille 2 protrudes inward relative to the inner surface 1d of the vertical grille 1. The protruding portion of the inner surface of the horizontal grille 2 increases the structural strength of the horizontal grille 2 and does not affect the aesthetics of the outer surface of the air outlet grille 10.

[0053] refer to Figure 7 and Figure 9 In some embodiments, the dimension of the horizontal bar 2 along its own airflow direction is the width of the horizontal bar 2. At least one horizontal bar 2 is a narrow bar 22, and at least one horizontal bar 2 is a wide bar 21. The maximum width G2 of the wide bar 21 is greater than the maximum width G1 of the narrow bar 22. The wide bar 21 and the narrow bar 22 are alternately arranged along the length direction F2 of the air outlet grille 10.

[0054] In the above technical solution, the horizontal grating 2 includes narrow grating 22 and wide grating 21, which allows for differentiated design based on actual air outlet requirements and structural strength requirements. The wide grating 21 is mainly used to bear the main structural load to enhance overall strength, while the narrow grating 22 is mainly used to reduce the overall weight of the air outlet grille 10 and guide the air outlet to optimize airflow distribution and reduce wind resistance. By rationally arranging the position and number of wide grating 21 and narrow grating 22, the material consumption of the air outlet grille 10 can be effectively reduced while maintaining the structural strength of the air outlet grille 10, further reducing manufacturing costs. The alternating arrangement of wide grating 21 and narrow grating 22 provides relatively stable structural support and air outlet guidance for the air outlet grille 10 in the length direction F2. This ensures overall strength while avoiding problems such as easy deformation of the air outlet grille 10 due to weak local structures. At the same time, it enhances the airflow guidance function of the air outlet grille 10, making the airflow smoother when passing through the air outlet grille 10, thereby effectively reducing turbulence and noise when the airflow passes through the air outlet grille 10.

[0055] refer to Figure 7 and Figure 9 In some embodiments, at least one vertical grid bar 1 is a widened grid bar 12, which widens inward at the intersection P with the horizontal grid bar 2. The intersection position refers to the location where the two grid bars intersect, or the vicinity of the intersection.

[0056] In the above technical solution, the widened grille 12 is widened inward at the intersection P with the horizontal grille 2, so that the vertical grille 1 has higher structural strength at the intersection P with the horizontal grille 2, thereby improving the overall strength and deformation resistance of the air outlet grille 10; at the same time, it does not affect the overall external visual effect of the air outlet grille 10.

[0057] In some embodiments, the grille body 10a is a one-piece injection-molded plastic part, thereby reducing costs and weight. For example, the grille body 10a is a one-piece injection-molded plastic part, and a decorative layer 10b is provided, thereby achieving the desired aesthetic effect while reducing costs.

[0058] In some embodiments, the decorative layer 10b includes at least one of the following: a hot stamping foil layer, a heat transfer layer, a UV screen printing layer, a UV oil layer, a vacuum evaporation layer, a screen printing color layer, and an offset printing layer. That is, the decorative layer 10b can be a single-layer structure or a multi-layer composite structure, achieving rich visual effects and textures through different process combinations.

[0059] Foil stamping is a decorative printing technique that transfers foil (such as metallic foil or colored foil) to the surface of a substrate using heat and pressure. The foil layer can be made of metallic or non-metallic materials. Metallic foils are primarily composed of metals (aluminum, copper, etc.), and the metal layer is deposited onto a base film via vacuum evaporation. Common examples include gold foil, silver foil, and copper foil, which produce a pure metallic luster. Non-metallic foils do not contain metallic components and rely on coatings to achieve decorative effects. These include colored foils (solid color, gradient, pearlescent coatings), holographic foils (laser coatings with 3D / iridescent effects), and matte foils (frosted coatings), thus achieving a metallic or special texture (including matte, frosted, brushed, pearlescent, fluorescent, etc.). Depending on the form of the outer surface 1c of the vertical grid strip 1 (e.g., flat or cylindrical), foil stamping techniques such as flat stamping, roll stamping, and cold stamping can be used to place the foil layer on the outer surface of the vertical grid strip 1, achieving overall visual unity or local embellishment effects.

[0060] For example, the decorative layer 10b can be a heat transfer layer, which utilizes the metal coating on the heat transfer film to be transferred to the outer surface 1c of the longitudinal grid strip 1 by hot pressing.

[0061] For example, the decorative layer 10b can be a UV screen printing layer, in which UV ink containing a photosensitive agent is transferred to the outer surface 1c of the longitudinal grid strip 1 by screen printing technology, and then cured by ultraviolet light to form a coating with special visual effects and functions.

[0062] For example, the decorative layer 10b can be a UV oil layer, which forms a high-gloss or matte protective layer on the outer surface 1c of the longitudinal grid strip 1 by a UV curing process.

[0063] For example, the decorative layer 10b can be a vacuum evaporation layer, in which metal or non-metal materials are evaporated and adhered to the surface of the vertical grid strip 1 in a high vacuum environment using physical vapor deposition technology to form a dense and uniform decorative film layer. For example, the decorative layer 10b can also be a screen-printed color layer, in which different colored inks are superimposed through multiple screen printing processes to transfer the pattern to the outer surface 1c of the vertical grid strip 1.

[0064] For example, the decorative layer 10b can be an offset printing layer, in which the pattern is directly printed onto the outer surface 1c of the longitudinal grid strip 1 using an offset printing process.

[0065] In the above technical solution, the decorative layer 10b can be any combination of the above processes to form a multi-layer composite structure, so as to achieve more complex patterns, color gradients and three-dimensional textures, and improve the weather resistance, wear resistance and adhesion of the decorative layer 10b. For example, a metallic base color can be formed by vacuum evaporation first, and then UV screen printing can be combined to achieve local high-gloss patterns, etc., to achieve a multi-layer and multi-process synergistic decorative effect.

[0066] In some embodiments, decorative layer 10b is a hot stamping layer, wherein the hot stamping layer is a foil layer made of metal foil and / or a metal-effect layer.

[0067] Among them, the imitation metal effect layer is a decorative layer 10b that is processed by physical or chemical processes to make the surface of non-metallic or metallic substrates present a similar metallic luster, texture and color. The imitation metal effect means that the decorative layer 10b has the characteristics of strong reflectivity (having the "mirror reflection" or "soft metallic reflection" unique to metal) and heavy texture.

[0068] It's worth noting that achieving a metallic effect with hot stamping doesn't necessarily require metal foil. Metal foil, non-metal foil, or other auxiliary processes can all be used. For example, non-metal foil (metallic coating) can simulate metallic luster by adding metallic pigments (such as aluminum or copper powder) to the foil coating. Other auxiliary processes can also be employed, such as applying a layer of high-gloss UV varnish after hot stamping on non-metal foil, which enhances the gloss of the metallic finish and further replicates the texture of metal foil.

[0069] In the above technical solution, the decorative layer 10b is a hot-stamping layer, which can increase the gloss of the outer surface of the air vent grille 10, giving it a metallic texture and enhancing its visual appeal, thereby improving the user experience. The air vent grille 10 can be manufactured using non-technical materials, thus reducing its production cost. Simultaneously, the hot-stamping layer effectively resists scratches and environmental aging during daily use, and also enhances the weather resistance (such as UV resistance and temperature difference resistance) and corrosion resistance of the outer surface of the air vent grille 10.

[0070] Reference Figure 1 In some embodiments, the air conditioner 100 is a cabinet air conditioner, the length direction F2 of the air outlet grille 10 is the up and down direction, and the air outlet grille 10 is located at the center of the front side of the air conditioner 100, or on the left and right sides of the air conditioner 100.

[0071] In the above technical solution, the length direction F2 of the air outlet grille 10 is vertical, so the air conditioner 100 has a larger air outlet range and angle in the vertical direction. The air outlet grille 10 is located in the center of the front side of the air conditioner 100. The width of the air outlet grille 10 can be set to be relatively large. The air outlet grille 10 is located on the left and right sides of the air conditioner 100, so it can send air to the left and right sides, thereby increasing the air outlet range of the air conditioner 100. The width of the air outlet grille 10 can be set to be relatively small.

[0072] Of course, this application is not limited to this. Air conditioner 100 can also be other types, such as wall-mounted air conditioner, air conditioner integrated unit (such as kitchen air conditioner or window air conditioner, etc.).

[0073] Other components of the air conditioner 100 according to the present invention, such as the fan and heat exchanger, as well as its operation, are known to those skilled in the art and will not be described in detail here.
