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 6 The air outlet grille 10 includes a grille body 10a and a decorative layer 10b. The grille body 10a includes a first grille bar 1 and a second grille bar 2. The first grille bar 1 and the second grille bar 2 intersect to form a grille hole 1a between the first grille bar 1 and the second grille bar 2. The angle at which the first grille bar 1 and the second grille bar 2 intersect is not limited; it can be an acute angle, a right angle, or an obtuse angle to form a rhomboid, rectangular, or polygonal grille hole 1a, thereby enhancing the aesthetics and airflow guiding effect of the air outlet grille 10. The form in which the first grille bar 1 and the second grille bar 2 intersect is not limited. For example, the first grille bar 1 can be located on the outside of the air outlet grille 10, and the second grille bar 2 can be located on the inside. The first grille bar 1 and the second grille bar 2 contact and are fixedly connected at the intersection point. Alternatively, one of the first grille bar 1 and the second grille bar 2 can be completely embedded inside the other, forming an integrated structure, improving the overall structural strength and surface flatness.

[0027] Reference Figures 3-6 The outer surface 1c of the first grid bar 1 protrudes outward relative to the outer surface 2c of the second grid bar 2. A decorative layer 10b is provided on the outer surface 1c of the first grid bar 1, and the first grid bar 1 and the second grid bar 2 are integrally connected. The decorative layer 10b can be a layered structure with certain functionality and / or decorative features, disposed on the outer surface 1c of the first grid bar 1. The material of the decorative layer 10b is not limited; for example, it can be plastic, metal, etc. The manner in which the decorative layer 10b is disposed on the outer surface 1c of the first grid bar 1 is not limited; for example, it can be combined with the outer surface of the first grid bar 1 by spraying, electroplating, vapor deposition, attachment, 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 decorative layer 10b allows for different colors, textures, or patterns on the air outlet grille 10, achieving a multi-layered visual effect. Simultaneously, it prevents the decorative layer 10b from covering the grille openings 1a, making the overall appearance of the air conditioner 100 more aesthetically pleasing. Furthermore, the choice of materials for the decorative layer 10b can 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. It is worth noting that, due to the relatively thin thickness of the decorative layer 10b, it is shown overlapping with the outer surface 1c of the first grille bar 1 in the attached drawings.

[0028] The outer surface 1c of the first grille 1 is designed to protrude further outward than the outer surface 2c of the second grille 2, meaning the first grille 1 is closer to the user. This allows the decorative layer 10b to be processed only on the outer surface 1c of the first grille 1, ensuring the overall visual shape of the air outlet grille 10 is 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, thus creating a sense of vertical visual extension and enhancing the vertical stretching effect of the space. Simultaneously, since the decorative layer 10b is only provided on the outer surface 1c of the protruding first grille 1, the material used for the decorative layer 10b can be reduced, resulting in lower processing costs and easier achievement of diverse appearances, such as high-gloss, brushed, or metallic textures, enhancing the overall quality of the air conditioner 100. For example, the air outlet grille 10 remains fixed whether the air conditioner 100 is turned on or off. By providing the decorative layer 10b on the air outlet grille 10, the appearance of the air conditioner 100 is improved. However, this application is not limited to this. In other embodiments of this application, the air vent grille 10 may also be configured to be movable, which will not be elaborated here.

[0029] The first grille bar 1 and the second grille bar 2 are integrally connected. The method of integral 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 integral 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 integrally injection molded, or one can be pre-processed and then the other can be processed by embedding injection molding to achieve an integral connection of the first grille bar 1 and the second grille bar 2. The integral connection makes the overall structural strength of the air outlet grille 10 more stable and less prone to deformation.

[0030] In the above technical solution, by setting an air outlet grille at the air outlet position of the air conditioner, 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 outer surface 1c of the first grille 1 protrudes outward relative to the outer surface 2c of the second grille 2, making it easy to process the decorative layer 10b only on the outer surface 1c of the first grille 1, and allowing the overall visual shape of the air outlet grille 10 to be dominated by the first grille 1, improving the aesthetics of the air conditioner 100. In addition, the intersection of the first grille 1 and the second grille 2 forms a grille hole 1a, which can guide and disperse the airflow blown out by the air conditioner 100, making the airflow more evenly distributed in the indoor space, avoiding the airflow from concentrating on a certain area, and improving the uniformity and comfort of indoor temperature regulation.

[0031] For example, the outer surface 1c of the first grille 1 extends in a straight line along the length direction of the first grille 1. In this way, by setting the length direction of the first grille 1 to extend along the length direction Z of the air outlet grille 10, the overall visual shape of the air outlet grille 10 can be dominated by the first grille 1, highlighting the length of the air outlet grille 10.

[0032] Reference Figure 6 In some embodiments, the length direction of the first grille 1 extends along the length direction Z of the air outlet grille 10. There are multiple first grille 1s, which are spaced apart along the width direction X of the air outlet grille 10. The dimension of the first grille 1 along its own (i.e., the first grille 1) airflow direction is the width of the first grille 1. At least one first grille 1 is a widened grille 12, which widens inward at the intersection P with the second grille 2. The intersection P refers to the position where the two grilles intersect or is nearby, that is, close to the intersection of the two grilles.

[0033] In the above technical solution, since the outer surface 1c of the first grille 1 protrudes outward relative to the outer surface 2c of the second grille 2, the reliability of the connection between the first grille 1 and the second grille 2 needs to be strengthened. Widening the grille 12 gives the first grille 1 higher structural strength at the junction P with the second grille 2, thereby improving the overall structural strength and deformation resistance of the air outlet grille 10. The widening of the grille 12 at the junction P with the second grille 2 towards the inner side (i.e., the upstream side of the air outlet grille 10) can enhance the structural connection strength, while not affecting the overall external visual effect of the air outlet grille 10, reducing the damage to the appearance caused by the widening of the grille 12.

[0034] Reference Figure 3 and Figure 6 In some embodiments, the widened grating 12 is located in the width-direction central region 10c of the air outlet grille 10. Two first gratings 1 located at the two sides of the width of the air outlet grille 10 along the width direction X are respectively side frames 11. The first grating 1 located between the side frames 11 and the widened grating 12 is a conventional grating 13. The maximum width E3 of the conventional grating 13 is less than the maximum width E2 of the widened grating 12. The ratio of the width C of the width-direction central region 10c to the width D of the air outlet grille 10 is 0.2-0.7. Exemplarily, the ratio of the width C of the width-direction central region 10c to the width D of the air outlet grille 10 can be 0.2, 0.3, 0.4, 0.5, 0.6, or 0.7, etc. The larger the width of the width-direction central region 10c and the more widened gratings 12 there are, the more beneficial it is to improving the structural stability of the central region of the air outlet grille 10.

[0035] In the above technical solution, a widened grating 12 is provided in the central region 10c of the width direction X of the air outlet grille 10, which increases the structural strength of the air outlet grille 10 in the width direction and reduces the possibility of deformation and damage. The first grating 1 is divided into a widened grating 12, a conventional grating 13 and a side frame 11 in the width direction X of the air outlet grille 10. The ratio of the width of the central region 10c to the width of the air outlet grille 10 is 0.2-0.7, which can meet the requirements of airflow regulation and structural strength, and also help control the manufacturing cost of the air outlet grille 10. At the same time, the side frame 11 serves as the edge support structure of the air outlet grille 10, forming a cooperative force system with the widened grating 12, improving the overall structural stability and bending resistance of the air outlet grille 10. The conventional grating 13 can effectively reduce material usage and reduce the overall weight of the air outlet grille 10 while ensuring uniform airflow distribution. Of course, the widened grating 12 also has the function of guiding airflow.

[0036] Reference Figure 3 and Figure 6In some embodiments, the second grille bars 2 are multiple and spaced apart along the length direction Z of the air outlet grille 10. The widened grille bar 12 includes sub-grate segments 121 located between two adjacent second grille bars 2, combined with... Figure 7 and Figure 8 The sub-grid segment 121 includes a widened segment 1211 and a main segment 1212. The width E11 of the first grid bar 1 at the widened segment 1211 is greater than the width E12 at the main segment 1212. The widened segment 1211 is connected to both ends of the main segment 1212 in the length direction Z of the air outlet grille 10. The end of the widened segment 1211 away from the main segment 1212 is connected to the second grid bar 2. The width E11 at the widened segment 1211 is the maximum width E2 of the widened grid bar 12. By placing the widened segment 1211 at both ends of the sub-grid segment 121 and connecting it to the second grid bar 2, In the above technical solution, multiple second grid bars 2 are arranged at Z-intervals along the length direction of the air outlet grille 10 and intersect with the first grid bars 1, thus forming a grid-like basic structure of the air outlet grille 10. The widened section 1211 enhances the bonding strength between the first grid bar 1 and the second grid bar 2 at the intersection, thereby improving the structural stability of the air outlet grille 10 at the intersection node. The width E1 of the widened section 1211 is greater than the width E2 of the main body section 1212, that is, the width E2 of the main body section 1212 is less than the width E1 of the widened section 1211, which can reduce the material usage of the sub-grid bar sections 121 and reduce the overall weight. In addition, maintaining a smaller width in the main body section 1212 helps with air outlet and reduces the decrease in air outlet efficiency caused by local obstruction. By reasonably configuring the size ratio of the widened section 1211 and the main body section 1212, the air outlet performance of the air outlet grille 10 can be further improved while meeting the structural strength requirements.

[0037] Reference Figure 6 and Figure 7 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.

[0038] In the above technical solution, the protruding part on the inner surface of the second grid bar 2 increases the structural strength of the second grid bar 2, thereby improving the support strength of the second grid bar 2 for the first grid bar 1.

[0039] 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 vent grille 10, thereby reducing the possibility of the air vent grille 10 loosening or shifting during use.

[0040] Reference Figure 6 and Figure 7In 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 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, combined with Figure 8 The maximum width G1 of the narrow grid bar 22 is less than the maximum width G2 of the wide grid bar 21. Exemplarily, the inner surface of the narrow grid bar 22 is flush with the inner surface of the widened section 1211, forming a continuous and flat surface on the inner side of the narrow grid bar 22 and the widened section 1211. This helps reduce airflow resistance and improves airflow smoothness. At least a portion of the inner surface of the wide grid bar 21 protrudes inward relative to the inner surface 1d of the first grid bar 1, thereby increasing the support strength of the wide grid bar 21 for the first grid bar 1.

[0041] 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.

[0042] Reference Figure 6 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.

[0043] 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.

[0044] Reference Figure 9 In some embodiments, the decorative layer 10b is located on a plane S1, in which case the outer surface 1c of the first grating 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.

[0045] Reference Figure 9 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 3 The 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.

[0046] Reference Figure 10 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. Exemplarily, the ratio of the length to the width of the air outlet grille 10 can be 2, 3, 4 or 5, etc., thus suitable for air conditioners 100 with elongated air outlets 71.

[0047] In the above technical solution, the length-to-width ratio of the air outlet grille 10 is greater than or equal to 2, and the length direction of the first grille bar 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 bar 1 and achieving a visual extension effect in the length direction Z of the air outlet grille 10. Moreover, since the length L of the air outlet grille 10 is greater than or equal to 2, it is beneficial to increase the air outlet range along the length direction Z of the air outlet grille 10.

[0048] 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.

[0049] Combination Figure 10 and Figure 11 A support strip 4 extending along the width direction X of the air outlet grille 10 is provided at the center of the grille 10 in the length direction Z. The outer surface 1c of the first grille 1 protrudes outward relative to the outer surface of the support strip 4. The inner side of the support strip 4 has a first connecting structure 41, which is combined with... Figure 13 The panel component 20 includes a support beam 73 located inside the air outlet grille 10. The support beam 73 is disposed opposite to the support strip 4, and the support beam 73 has a second connecting structure 731. The first connecting structure 41 and the second connecting structure 731 are connected in cooperation. For example, the first connecting structure 41 is a buckle, and the second connecting structure 731 is a slot. The quick connection between the support strip 4 and the support beam 73 is achieved through the cooperation of the buckle and the slot.

[0050] In the above technical solution, for the detachable air outlet grille 10, a connecting structure is provided on the support bar 4 and the support beam 73, so that the middle part of the air outlet grille 10 in the Z-direction of its length forms a fixed connection structure with the panel component 20. This makes the air outlet grille 10 less prone to loosening or falling off, effectively improving the stability and reliability of the installation. At the same time, the support bar 4 is located in the middle of the air outlet grille 10, which can stabilize the overall structure of the air outlet grille 10 in the middle, reducing the possibility of deformation or damage to the air outlet grille 10.

[0051] Reference Figures 12-15 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 mounted on the panel component 20 and located at the air outlet 71. The air conditioner 100 includes an air guide plate 30, which is located inside the air outlet grille 10. The length direction of the air guide plate 30 extends along the length direction Z of the air outlet grille 10. Figure 14 and Figure 15 Multiple air guide plates 30 are arranged at intervals along the width direction X 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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 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 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] In some embodiments, the 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] Reference Figure 1In 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.

[0068] 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.

[0069] 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.).
