[0022] 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.

[0023] 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.

[0024] Hereinafter, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present invention will be described.

[0025] Reference Figure 1 and Figure 2 The air conditioner 100 includes an air outlet grille 10, which is used for air outlet of the air conditioner 100. Along the airflow direction of the air outlet grille 10, the two sides of the air outlet grille 10 are the inner side and the outer side, respectively. The inner side is the upstream side of the airflow direction of the air outlet grille 10, and the outer side is the downstream side.

[0026] Reference Figure 3 and Figure 4 The air outlet grille 10 includes a grille body 10a and a decorative layer 10b. The grille body 10a includes a plurality of first grille bars 1 and a plurality of second grille bars 2. The length direction of the first grille bars 1 extends along the length direction Z of the air outlet grille 10, and the plurality of first grille bars 1 are spaced apart along the width direction X of the air outlet grille 10. The length direction of the second grille bars 2 extends along the width direction X of the air outlet grille 10, and the plurality of second grille bars 2 are spaced apart along the length direction Z of the air outlet grille 10. The decorative layer 10b can be disposed on the outer surface 1c of the first grille bars 1. It is worth noting that, since the decorative layer 10b is relatively thin, it is shown to overlap with the outer surface 1c of the first grille bars 1 in the accompanying drawings.

[0027] The decorative layer 10b can be a layered structure with certain functions and / or decorations disposed on the outer surface 1c of the first grille 1. The material of the decorative layer 10b is not limited. For example, the material of the decorative layer 10b can be plastic, metal, etc. The way in which the decorative layer 10b is disposed on the outer surface 1c of the first grille 1 is not limited. For example, the decorative layer 10b can be combined with the outer surface of the first grille 1 by spraying, electroplating, vapor deposition, pasting, bonding, hot pressing, magnetic attraction, hot foil stamping, screen printing, offset printing, etc. Of course, the decorative layer 10b can be a single layered structure or a composite layered structure. The setting of the decorative layer 10b can make the air outlet grille 10 have different colors, textures or patterns, to achieve a multi-layered visual effect, while avoiding the decorative layer 10b covering the grille holes 1aa, making the overall appearance of the air conditioner 100 more beautiful. The selection of materials for the decorative layer 10b can also enhance the weather resistance (such as UV resistance and temperature difference resistance) and corrosion resistance of the outer surface of the air outlet grille 10.

[0028] The second grid bar 2 intersects with the first grid bar 1 to form a grid hole 1a between the first grid bar 1 and the second grid bar 2. The length direction of the second grid bar 2 extends along the width direction X of the air outlet grille 10. Multiple second grid bars 2 are spaced apart along the length direction Z of the air outlet grille 10. The length direction Z of the air outlet grille 10 is perpendicular to the width direction X of the air outlet grille 10. The ratio of the distance M2 between two adjacent second grid bars 2 to the distance M1 between two adjacent first grid bars 1 is greater than or equal to 2. The first grid bar 1 and the second grid bar 2 are integrally connected.

[0029] For example, the first grille 1 can be located on the outside of the air outlet grille 10, and the second grille 2 can be located on the inside. The first grille 1 and the second grille 2 are in contact and fixedly connected at the intersection. Alternatively, one of the first grille 1 and the second grille 2 can be completely embedded in the other to form an integrated structure, thereby improving the overall structural strength and surface flatness.

[0030] The ratio of the spacing M2 between two adjacent second grilles 2 to the spacing M1 between two adjacent first grilles 1 is greater than or equal to 2. That is, the second grilles 2 are arranged more sparsely and the first grilles 1 are arranged more densely. In addition, the length direction of the first grille 1 extends along the length direction of the air outlet grille 10. At the same time, a decorative layer 10b is provided on the outer surface 1c of the first grille 1. As a result, the user will first notice the first grille 1 that extends along the length direction of the air outlet grille 10. This makes the overall visual shape of the air outlet grille 10 dominated by the first grille 1. For example, the extension direction of the first grille 1 is consistent with the length direction of the main body of the air conditioner 100, thereby forming a sense of vertical visual extension and enhancing the vertical stretching visual effect of the space.

[0031] The method of integrated connection is not limited; for example, it can be injection molding, die casting, etc. When the air outlet grille 10 is made of non-metallic material, the integrated connection of the first grille bar 1 and the second grille bar 2 can be achieved using injection molding. For example, the first grille bar 1 and the second grille bar 2 can be injection molded as a single piece, or one can be pre-processed and then the other can be processed by embedding injection molding to achieve the integrated connection of the first grille bar 1 and the second grille bar 2. Integrated connection makes the overall structural strength of the air outlet grille 10 more stable and less prone to deformation.

[0032] In the above technical solution, by setting an air outlet grille 10 at the air outlet position of the air conditioner 100, the opening and closing door can be eliminated under normal circumstances, simplifying the structure and reducing costs. The first grille 1 and the second grille 2 are integrated, making the overall structure of the air outlet grille 10 more stable, and facilitating production and assembly, improving production efficiency, reducing assembly gaps and stress concentration problems that may occur when assembling multiple parts, and enhancing the structural strength of the air outlet grille 10, making it less prone to deformation and damage, and extending the service life of the air outlet grille 10. The second grille 2 is arranged more sparsely, while the first grille 1 is arranged more densely. At the same time, a decorative layer 10b is set on the outer surface 1c of the first grille 1, so that the overall visual shape of the air outlet grille 10 can be dominated by the first grille 1. In addition, the first grille 1 and the second grille 2 intersect to form a grille hole 1a. The grille hole 1a can guide and disperse the airflow blown out by the air conditioner 100, so that the airflow is more evenly distributed in the indoor space, avoiding the airflow from being concentrated in a certain area, and improving the uniformity and comfort of indoor temperature regulation.

[0033] 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.

[0034] Reference Figure 3 In some embodiments, the ratio of the spacing M2 between two adjacent second grid bars 2 to the spacing M1 between two adjacent first grid bars 1 is 3-12. For example, the ratio of the spacing M2 between two adjacent second grid bars 2 to the spacing M1 between two adjacent first grid bars 1 can be 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, etc.

[0035] In the above technical solution, the ratio of the spacing M2 between two adjacent second grilles 2 to the spacing M1 between two adjacent first grilles 1 is 3-12, making the second grilles 2 appear more sparse and further emphasizing the vertical extension effect brought about by the dense arrangement of the first grilles 1. Simultaneously, the larger spacing ratio of the second grilles 2 facilitates airflow through the grille holes 1a, reducing wind resistance and improving air outlet efficiency. Furthermore, this spacing ratio effectively reduces turbulent noise generated during airflow, improving the quietness of the air conditioner's operation. While ensuring structural strength, the aerodynamic performance is optimized, resulting in a softer and more uniform airflow.

[0036] Reference Figure 3 In some embodiments, the spacing M1 between two adjacent first grid bars 1 is 4mm-9mm, and the spacing M2 between two adjacent second grid bars 2 is 40mm-90mm. For example, the spacing M1 between two adjacent first grid bars 1 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc., and the spacing M2 between two adjacent second grid bars 2 can be 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, etc.

[0037] In the above technical solution, the spacing M2 between two adjacent second grille bars 2 is much larger than the spacing M1 between two adjacent first grille bars 1, thus forming a "combination of sparse and dense" air outlet grille structure. The large spacing of the second grille bars 2 can reduce the local resistance when the airflow passes through, while the small spacing of the first grille bars 1 can refine the airflow, making the air outlet of the air conditioner 100 more gentle. In addition, the larger spacing of the second grille bars 2 can reduce the number of second grille bars 2, thereby reducing material costs, while the dense arrangement of the first grille bars 1 can enhance the local rigidity of the grille body 10a and improve the structural stability of the air outlet grille 10.

[0038] Reference Figure 4 and Figure 5 In some embodiments, at least a portion of the inner surface 2d of at least one second grid bar 2 protrudes inward relative to the inner surface 1d of the first grid bar 1.

[0039] In the above technical solution, the protruding part on the inner surface of the second grille 2 increases the structural strength of the second grille 2, which is beneficial to improving the overall structural strength of the air outlet grille 10.

[0040] Furthermore, in some embodiments, the protruding portion of the second grille 2 can also be used to form a mating structure with other components. For example, the protruding portion can engage with a specific structure on the panel component 20 to fix the air outlet grille 10, thereby reducing the possibility of the air outlet grille 10 loosening or shifting during use.

[0041] Reference Figure 4 and Figure 5In some embodiments, the dimension of the second grid bar 2 along its own airflow direction is the width of the second grid bar 2, the dimension of the first grid bar 1 along its own airflow direction is the width of the first grid bar 1, and the maximum width of at least one second grid bar 2 is greater than the maximum width of at least one first grid bar 1.

[0042] In the above technical solution, since the second grid bar 2 is arranged more sparsely and the first grid bar 1 is arranged more densely, in order to ensure the stability of the overall structure of the air outlet grille 10, the maximum width of the second grid bar 2 is greater than the maximum width of the first grid bar 1, which can effectively improve the deformation resistance of the air outlet grille 10 and provide force support for the denser first grid bar 1.

[0043] For example, the second grid bar 2 includes a narrow grid bar 22 and a wide grid bar 21, the maximum width of the second grid bar 2 is the maximum width G2 of the wide grid bar 21, and the first grid bar 1 includes a widening segment 1211, the maximum width of the first grid bar 1 is the maximum width E11 of the widening segment 1211.

[0044] Reference Figure 4 and Figure 5 In some embodiments, the dimension of the second grid bar 2 along its own airflow direction is the width of the second grid bar 2. At least two second grid bars 2 have different widths. At least one second grid bar 2 is a narrow grid bar 22, and at least one second grid bar 2 is a wide grid bar 21. The maximum width G2 of the wide grid bar 21 is greater than the maximum width G1 of the narrow grid bar 22.

[0045] In the above technical solution, the second grid bar 2 includes a narrow grid bar 22 and a wide grid bar 21, which allows for differentiated design based on actual air outlet requirements and structural strength requirements. The wide grid bar 21 can mainly bear the main structural load to enhance the overall structural strength, while the narrow grid bar 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 the wide grid bar 21 and the narrow grid bar 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.

[0046] Reference Figure 4 In some embodiments, wide grille bars 21 and narrow grille bars 22 are alternately arranged along the length direction Z of the air outlet grille 10.

[0047] In the above technical solution, the wide grille 21 and the narrow grille 22 are arranged alternately, so that the air outlet grille 10 has a relatively stable structural support and air guiding function in the length direction Z of the air outlet grille 10. While ensuring the overall structural strength, it can avoid problems such as the air outlet grille 10 being easy to deform due to excessive or insufficient local structure. At the same time, it can improve the airflow guiding function of the air outlet grille 10, making the airflow smoother when passing through the air outlet grille 10, thereby effectively reducing the turbulence and noise of the airflow passing through the air outlet grille 10.

[0048] Reference Figure 6 and Figure 7 In some embodiments, the length direction of the air outlet grille 10 is vertical, and at least one second grille 2 is a guide horizontal grille 23, combined with Figure 8 and Figure 9 At least one of the upper and lower surfaces of the air guide bar 23 is configured as an air guide surface 231, which is inclined upward or downward relative to the horizontal surface in a direction from the inside to the outside.

[0049] The air guide surface 231 is the surface on the air guide horizontal bar 23 that directly contacts and guides the airflow. Either the upper or lower surface of the air guide horizontal bar 23 can be configured as the air guide surface 231, or both surfaces can be configured as the air guide surface 231 to collaboratively guide the airflow upwards or downwards relative to the horizontal surface. The tilt angle of the air guide surface 231 of the second bar 2 can be set according to the air outlet requirements.

[0050] For example, the tilt angle of the air guide surface 231 can be set between 10° and 45° to adapt to the air supply angle adjustment requirements in different scenarios. When the air guide surface 231 is tilted downwards, the airflow can be guided upwards, which is conducive to the sinking of warm air in winter; when the air guide surface 231 is tilted upwards, it helps the cold air to rise in summer, improving the air conditioning energy efficiency and human comfort.

[0051] In the above technical solution, the second grid bar 2 is a guide horizontal grid bar 23. Thus, the second grid bar 2 not only undertakes the structural support function, but also has the function of guiding air. By guiding the airflow through the inclined air guide surface 231 on its surface, the air outlet angle in the vertical direction can be adjusted, thereby improving the practicality of the air conditioner 100.

[0052] Reference Figure 6 and Figure 7 In some embodiments, the air outlet grille 10 is divided into two parts above and below the dividing line S1, with at least one air guide horizontal bar 23 provided above and below the dividing line S1, respectively. Figure 8 and Figure 9The air guide surface 231 of the air guide bar 23 located above the dividing line S1 is inclined upward relative to the horizontal surface in the direction from the inside to the outside, and the air guide surface 231 of the air guide bar 23 located below the dividing line S1 is inclined downward relative to the horizontal surface in the direction from the inside to the outside.

[0053] For example, the air guide surface 231 of the air guide bar 23 above the dividing line S1 can gradually increase in the upward angle relative to the horizontal plane along the direction from the inside to the outside. That is, the inclination angle b2 of the air guide bar 23 is greater than b1. Similarly, the air guide surface 231 of the air guide bar 23 below the dividing line S1 can gradually increase in the downward angle relative to the horizontal plane along the direction from the inside to the outside. That is, the inclination angle h1 of the air guide bar 23 is greater than h2. Thus, the gradient design of the inclination angle of the air guide surface 231 in the upper and lower sections enables the airflow to form a multi-layered diffusion in the vertical direction, effectively reducing the direct blowing sensation caused by concentrated airflow and improving the uniformity and comfort of air delivery.

[0054] In the above technical solution, by dividing the air outlet grille 10 into upper and lower parts, and making the air guide surface 231 of the upper air guide bar 23 inclined upward and the air guide surface 231 of the lower air guide bar 23 inclined downward, the vertical air guiding range of the air conditioner 100 can be expanded, making the indoor air circulation more uniform and improving the uniformity of indoor air conditioning. Because the air guide surface 231 of the air guide bar 23 is inclined, the airflow will not directly impact surrounding objects or people when it flows out of the grille, thereby reducing the discomfort caused by direct cold air blowing, and at the same time reducing the noise generated by airflow disturbance.

[0055] Reference Figure 10 and Figure 11 In some embodiments, the outer surface 1c of the first grid bar 1 protrudes outward relative to the outer surface 2c of the second grid bar 2, that is, the first grid bar 1 is closer to the user side, so that the decorative layer 10b can be processed only on the outer surface 1c of the first grid bar 1.

[0056] Reference Figure 10 The decorative layer 10b is located on a plane S1, at which point the outer surface 1c of the first grid bar 1 is located in the same plane; or refer to Figure 3 The decorative layer 10b is located on a cylindrical surface S2, the axis of which extends along the length direction Z of the air outlet grille 10, and the outer surface 1c of the first grille 1 is located in the same cylindrical surface.

[0057] Reference Figure 11 The decorative layer 10b is located on a plane S1. The structure of the air vent grille 10 is relatively simple, which can reduce the manufacturing difficulty. (Refer to...) Figure 3The decorative layer 10b is located on a cylindrical surface S2, which can adapt to the curved appearance of the air conditioner 100, increase the air outlet range and angle, and make the air outlet grille 10 match the curvature of the air conditioner 100 casing.

[0058] Reference Figure 6 In some embodiments, the ratio of the length L of the air outlet grille 10 to the width M of the air outlet grille 10 is greater than or equal to 2. For example, the ratio of the length L of the air outlet grille 10 to the width M of the air outlet grille 10 can be 2, 3, 4, 5, 6, 7, 8, etc., thus suitable for air conditioners 100 with elongated air outlets 71.

[0059] In the above technical solution, the ratio of the length L to the width M of the air outlet grille 10 is greater than or equal to 2, and the length direction of the first grille 1 extends along the length direction Z of the air outlet grille 10, thereby facilitating the setting of the decorative layer 10b on the outer surface of the first grille 1 and achieving a visual extension effect in the length direction Z of the air outlet grille 10.

[0060] Reference Figure 12 In some embodiments, the air conditioner 100 includes a panel component 20 on which an air outlet 71 is formed. An air outlet grille 10 is detachably mounted on the panel component 20 and located at the air outlet 71 (wherein, the detachable connection method is not limited, for example, it can be a snap-fit, screw connection, or connection through a quick-release structure, etc.), thereby facilitating the cleaning of the air outlet grille 10.

[0061] The air conditioner 100 includes an air guide plate 30, which is located inside the air outlet grille 10. The length of the air guide plate 30 extends along the length Z of the air outlet grille 10. Figure 13 and Figure 14 The air guide plates 30 are multiple and spaced apart along the width direction of the air outlet grille 10. The panel component 20 includes a ventilation beam 74 located inside the air guide plate 30. The air guide plate 30 and the ventilation beam 74 are rotatably engaged (for example, the ventilation beam 74 is provided with a shaft hole, the air guide plate 30 is provided with a rotating shaft, and the rotating shaft is inserted into the shaft hole in the radial direction to achieve rotatable engagement). The ventilation beam 74 is formed with a ventilation opening 741 that runs through the length direction Z of the air outlet grille 10.

[0062] In the above technical solution, the air conditioner 100 includes an air guide plate 30, which is located inside the air outlet grille 10. The air guide plate 30 can guide and regulate the airflow before it passes through the air outlet grille 10, thereby improving the uniformity and comfort of the airflow. The air guide plate 30 extends along the length direction Z of the air outlet grille 10, consistent with the extension direction of the first grille, which helps the airflow to be blown out smoothly longitudinally, reducing airflow turbulence and improving air delivery efficiency.

[0063] In the above technical solution, the panel component 20 includes a ventilation beam 74 located inside the air guide plate 30. The ventilation beam 74 provides stable support and rotational coordination for the air guide plate 30, ensuring smooth operation of the air guide plate 30 during rotation. Simultaneously, a ventilation opening 741 extending along the Z-direction of the air outlet grille 10 and connected to the air outlet 71 is provided on the ventilation beam 74, allowing airflow to pass through the ventilation beam 74. This reduces the obstruction effect of the ventilation beam 74 on airflow, allowing cold air to flow obliquely upwards through the ventilation opening 741 or hot air to flow obliquely downwards. This ensures that cold air reaches a higher height and hot air reaches a lower area, improving temperature uniformity along the room's height and enhancing comfort.

[0064] 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.

[0065] Hot 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 D / 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 first grid strip 1 (e.g., flat or cylindrical), hot 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 first grid strip 1, achieving overall visual unity or local embellishment effects.

[0066] 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 first grid 1 by hot pressing.

[0067] 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 first grid 1 by screen printing technology, and then cured by ultraviolet light to form a coating with special visual effects and functions.

[0068] 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 first grid 1 through a UV curing process.

[0069] 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 first grid 1 in a high vacuum environment using physical vapor deposition technology to form a dense and uniform decorative film layer. Alternatively, the decorative layer 10b can 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 first grid 1.

[0070] 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 first grid 1 using an offset printing process.

[0071] 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-layered and multi-process synergistic decorative effect, making the product appearance more layered and technological.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] In some embodiments, the first grid bar 1 and the second grid bar 2 are integrally injection-molded plastic parts, thereby reducing costs and weight. For example, the first grid bar 1 and the second grid bar 2 are integrally injection-molded plastic parts, and a decorative layer 10b is provided, thereby achieving the desired appearance effect while reducing costs.

[0077] Reference Figure 1 In some embodiments, the air conditioner 100 is a cabinet air conditioner, and the length direction Z of the air outlet grille 10 is vertical. As a result, the air conditioner 100 has a larger air outlet range and angle in the vertical direction. The length direction of the first grille 1 extends in the vertical direction, thereby creating a sense of vertical visual extension and enhancing the vertical stretching visual effect of the air conditioner cabinet.

[0078] The location of the air outlet grille 10 is not limited. For example, the air outlet grille 10 can be located in the center of the front of the air conditioner unit, in which case the width of the air outlet grille 10 can be set relatively large. Alternatively, the air outlet grille 10 can be located on the left or right sides of the air conditioner unit, in which case the width of the air outlet grille 10 can be set relatively small.

[0079] 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.).
