[0099] 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.

[0100] 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.

[0101] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0102] According to the embodiment of the present utility model, the air conditioner 100, such as Figures 1-3 As shown, the air conditioner 100 has an air outlet grille 1 on its front side, which defines a portion of the air conditioner 100's exterior surface. The length direction of the air outlet grille 1 is consistent with the length direction Y of the air conditioner 100, and the width direction of the air outlet grille 1 is consistent with the width direction X of the air conditioner 100. The outer contour width Kn of the air outlet grille 1 accounts for 30%-100% of the total width Km of the air conditioner 100, and the outer contour length Ln of the air outlet grille 1 accounts for 30%-100% of the total length Lm of the air conditioner 100. The orthographic projection area Δn of the outer contour of the air outlet grille 1 along the front-rear direction accounts for 9%-100% of the orthographic projection area Δm of the outer contour of the air conditioner 100 along the front-rear direction.

[0103] Air conditioner 100 dissipates air through air outlet grille 1. Air outlet grille 1 not only serves a ventilation function but also defines a portion of the exterior surface of air conditioner 100. Specifically, the air outlet grille 1 defines a portion of the exterior surface of air conditioner 100, meaning that a portion of the exterior surface of air conditioner 100 is the outer surface of air outlet grille 1. Since air outlet grille 1 directly functions as an exterior component, structures such as door opening / closing mechanisms and door opening / closing actuators are omitted on the outer side of air outlet grille 1, simplifying the structure of air conditioner 100 and reducing costs.

[0104] Furthermore, since the length and width of the air outlet grille 1 match the length and width of the air conditioner 100, the air conditioner 100 can provide a larger installation space for the air outlet grille 1, which is conducive to increasing the size of the air outlet grille 1, thereby increasing the air outlet range of the air conditioner 100, thus providing a basis for realizing the design of the air conditioner 100's full air outlet.

[0105] Optionally, the outer contour width Kn of the air outlet grille 1 accounts for 30%, 50%, 60%, 95%, 100%, etc., of the total width Km of the air conditioner 100. Optionally, the outer contour length Ln of the air outlet grille 1 accounts for 30%, 50%, 60%, 95%, 100%, etc., of the total length Lm of the air conditioner 100. Optionally, the orthographic projection area Δn of the outer contour of the air outlet grille 1 along the front-back direction accounts for 9%, 25%, 36%, 50%, 90.25%, 100%, etc., of the orthographic projection area Δm of the outer contour of the air conditioner 100 along the front-back direction. The wide range of selectable width and length dimensions of the air outlet grille 1 allows for a wide range of selectable area, making the arrangement of the air outlet grille 1 more flexible.

[0106] According to the embodiment of the present utility model, the air outlet grille 1 of the air conditioner 100 serves as an exterior component, eliminating the need for the door opening and closing mechanism and the door opening and closing drive mechanism, simplifying the air conditioner structure and reducing costs. Furthermore, since the length and width directions of the air outlet grille 1 correspond to the length and width directions of the air conditioner, the front space of the air conditioner 100 can be fully utilized, allowing the size of the air outlet grille 1 to be increased as needed to facilitate large-scale air delivery.

[0107] In some embodiments of this utility model, the air outlet grille 1 satisfies at least one of the first, second, and third conditions. The first condition is that the air outlet grille 1 is centrally located in the width direction X of the air conditioner 100, and the outer contour width Kn of the air outlet grille 1 accounts for 70%-90% of the total width Km of the air conditioner 100. The second condition is that the outer contour length Ln of the air outlet grille 1 accounts for 50%-90% of the total length Lm of the air conditioner 100. The third condition is that the orthographic projection area Δn of the outer contour of the air outlet grille 1 along the front-back direction accounts for 50%-81% of the orthographic projection area Δm of the outer contour of the air conditioner 100 along the front-back direction.

[0108] When the air outlet grille 1 meets the first condition, the air outlet grille 1 is centered in the width direction of the air conditioner 100, and the arrangement of the air outlet grille 1 is more coordinated; and the air outlet grille 1 is wider, which is conducive to increasing the air supply range in the width direction of the air conditioner 100.

[0109] Optionally, the outer contour width Kn of the air outlet grille 1 accounts for 70%, 75%, 80%, 85%, 90% of the total width Km of the air conditioner 100.

[0110] When the air outlet grille 1 meets the second condition, its length is relatively large, which is beneficial to increasing the air supply range in the width direction of the air conditioner 100. Optionally, the outer contour length Ln of the air outlet grille 1 accounts for 50%, 60%, 70%, 80%, 90%, etc. of the total length Lm of the air conditioner 100.

[0111] When the air outlet grille 1 meets the third condition, the area of ​​the air outlet grille 1 is larger, and the air outlet area through the air outlet grille 1 increases, which is beneficial to increasing the air supply range of the air conditioner 100.

[0112] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the front panel 2 is provided on the front side of the air conditioner 100. The front panel 2 defines a part of the appearance surface of the air conditioner 100. The front panel 2 is located on at least one side of the air outlet grille 1 in the length direction. The width direction X of the air conditioner 100 is the lateral direction of the front panel 2. The two lateral edges of the front panel 2 are approximately aligned with the two width edges of the air outlet grille 1. The air conditioner 100 forms a first slit 41 extending along the length direction of the air conditioner 100 on both sides of the width of the air outlet grille 1, and forms a second slit 42 extending along the length direction Y of the air conditioner 100 on both sides of the lateral direction of the front panel 2. The first slit 41 and the second slit 42 are arranged and connected along the length direction of the air conditioner 100 to form a long slit 4a.

[0113] The front panel 2 defines a portion of the exterior surface of the air conditioner 100, meaning that a part of the exterior surface of the air conditioner 100 is the outer surface of the front panel 2. The front panel 2 can be provided on one side of the air outlet grille 1 along its length, or it can be provided on both sides of the air outlet grille 1 along its length.

[0114] The horizontal edges of the front panel 2 and the width edges of the air outlet grille 1 can be aligned in the width direction of the air conditioner 100, or the horizontal edges of the front panel 2 can protrude slightly or be slightly lower than the width edges of the air outlet grille 1 in the width direction.

[0115] The two sides of the air vent grille 1 are spaced apart from the main structure of the air conditioner 100 to form a first slit 41, and the two sides of the front panel 2 are spaced apart from the main structure of the air conditioner 100 to form a second slit 42. The two sides of the front panel 2 are roughly aligned with the two sides of the air vent grille 1, which helps to align the first slit 41 and the second slit 42 and improves the overall integrity of the long slit 4a.

[0116] Because the air conditioner 100 forms a first slit 41 on both sides of the width of the air outlet grille 1 and a second slit 42 on both sides of the width of the front panel 2, the air outlet grille 1 and the front panel 2 have a forward-protruding visual feature, which makes the air conditioner 100 more three-dimensional. Furthermore, the first slit 41 and the second slit 42 are connected along the length direction to form a long slit 4a, which can improve the integrity of the air outlet grille 1 and the front panel 2, thereby making the front appearance of the air conditioner 100 more integrated.

[0117] In some embodiments of this utility model, the length direction of the air outlet grille 1 is vertical, and front panels 2 are provided on both the upper and lower sides of the air outlet grille 1, such as... Figure 5 As shown, second slits 42 extending vertically are formed on the left and right sides of the front panel 2 located above the air vent grille 1, respectively. Figure 6 As shown, the left and right sides of the air vent grille 1 respectively form a first slit 41 extending in the vertical direction, as... Figure 7 As shown, second slits 42 extending vertically are formed on the left and right sides of the front panel 2 located below the air vent grille 1. Figure 4 As shown, the first slit 41 and the second slit 42 on the left side are connected to form a long slit 4a, and the first slit 41 and the second slit 42 on the right side are connected to form a long slit 4a.

[0118] In some embodiments of this utility model, such as Figures 8-11 As shown, the length direction Y of the air conditioner 100 is the vertical direction, the width direction X of the air conditioner 100 is the horizontal direction, and the dimensional difference Gi between the front panel 2 and the air outlet grille 1 on the left and right sides is 0mm-50mm.

[0119] In some embodiments of this utility model, the length direction of the air conditioner 100 is vertical, and the width direction is horizontal. There are two front panels 2, namely an upper panel 21 and a lower panel 22. The upper panel 21 is located above the air outlet grille 1, and the lower panel 22 is located below the air outlet grille 1. The left and right edges of the upper panel 21 and the lower panel 22 are aligned. There is a dimensional difference between the air outlet grille 1 and the upper panel 21; the dimension of the air outlet grille 1 in the horizontal direction is greater than or less than the dimension of the upper panel 21 in the horizontal direction.

[0120] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the air vent grille 1 includes longitudinal grille bars 11, the front surface of which forms the front surface of the air vent grille 1, and the longitudinal grille bars 11 extend along the length of the air vent grille 1 and extend to the front panel 2 at their ends.

[0121] The longitudinal grille 11 extends along the length of the air outlet grille 1, and the front surface of the longitudinal grille 11 constitutes the front surface of the air outlet grille 1. Therefore, the longitudinal grille 11 also participates in defining a portion of the appearance of the air conditioner 100. By extending the longitudinal grille 11 along the length of the air conditioner 100 to the front panel 2, the front surface of the air outlet grille 1 and the front surface of the front panel 2 are joined together, making the appearance of the air outlet grille 1 and the front panel 2 form a whole, improving the integrity of the air outlet grille 1 and the front panel 2, thereby making the overall appearance of the front of the air conditioner 100 more integrated.

[0122] In some embodiments of this utility model, the front surface of the front panel 2 and the front surface of the air vent grille 1 are approximately coplanar on the same plane or the same arc surface.

[0123] Coplanarity with the same plane or coplanarity with the same arc surface means that, on a projection plane perpendicular to the length direction of the air conditioner 100, the orthographic projection of the front surface of the front panel 2 and the orthographic projection of the front surface of the air outlet grille 1 are collinear.

[0124] The front surface of the front panel 2 is approximately coplanar with the front surface of the air vent grille 1, which means that the front surface of the front panel 2 and the front surface of the air vent grille 1 are at the same height in the front-rear direction, or the front surface of the front panel 2 is slightly protruding or slightly lower than the front surface of the air vent grille 1 in the front-rear direction.

[0125] When the front surface of the front panel 2 and the front surface of the air vent grille 1 are approximately coplanar on the same arc surface, the arc surface can be a forward-convex outward arc surface or a rearward-convex inward arc surface. For example... Figure 5 , Figure 6 and Figure 7 As shown, the width L of the arc surface in the left and right directions is 100mm-350mm, and the arch height K of the arc surface is less than 100mm.

[0126] Optionally, the width L of the curved surface in the left-right direction is 100mm, 150mm, 200mm, 300mm, 360mm, etc.

[0127] Optionally, the arch height K can be 1mm, 20mm, 50mm, 75mm, 100mm, etc.

[0128] In some embodiments of this utility model, such as Figure 12 , Figure 13 and Figure 14As shown, the front surface of the air vent grille 1 and the front surface of the front panel 2 have a dimensional difference Gr in the front-rear direction. The dimensional difference Gr between the front surface of the air vent grille 1 and the front surface of the front panel 2 is 0mm-50mm.

[0129] In some embodiments of this utility model, such as Figure 12 , Figure 13 and Figure 14 As shown, the air conditioner 100 has its length direction in the vertical direction and its width direction in the horizontal direction. It has two front panels 2, namely an upper panel 21 and a lower panel 22. The upper panel 21 is located above the air outlet grille 1, and the lower panel 22 is located below the air outlet grille 1. The front surfaces of the upper panel 21 and the lower panel 22 are coplanar. There is a dimensional difference between the front surface of the air outlet grille 1 and the front surface of the upper panel 21. The front surface of the air outlet grille 1 protrudes beyond the front surface of the upper panel 21 in the longitudinal direction, or the front surface of the air outlet grille 1 is lower than the front surface of the upper panel 21 in the longitudinal direction.

[0130] Optionally, the dimensional difference Gr between the front surface of the air vent grille 1 and the front surface of the front panel 2 is 0mm, 1mm, 5mm, 12mm, 50mm, etc.

[0131] In some embodiments of this utility model, such as Figure 1 As shown, the length of the air conditioner 100 is vertical, and its width is horizontal. There are two front panels 2, namely an upper panel 21 and a lower panel 22. Figure 12 , Figure 15 and Figure 16 As shown, the upper panel 21 is located above the air outlet grille 1, and the lower end of the upper panel 21 covers the front side of the upper end of the air outlet grille 1. The lower panel 22 is located below the air outlet grille 1, and the upper end of the lower panel 22 covers the front side of the lower end of the air outlet grille 1. The upper panel 21 has an upper slit 43 extending in the left-right direction on its top side, and the left and right ends of the upper slit 43 are respectively connected to the upper ends of two long slits 4a. And / or, the lower panel 22 has a lower slit 44 extending in the left-right direction on its bottom side, and the left and right ends of the lower slit 44 are respectively connected to the lower ends of two long slits 4a.

[0132] Optionally, an upper slit 43 is provided on the top side of the upper plate 21; alternatively, a lower slit 44 is formed on the bottom side of the lower plate 22; or alternatively, an upper slit 43 is formed on the top side of the upper plate 21, and a lower slit 44 is formed on the bottom side of the lower plate 22.

[0133] The air conditioner 100 forms a first slit 41 on the left and right sides of the air outlet grille 1, and a second slit 42 on the left and right sides of the top plate 21. The air conditioner 100 also forms a second slit 42 on the left and right sides of the bottom plate 22. The upper and lower ends of the first slit 41 are connected to the second slit 42 to form a long slit 4a. The long slit 4a, the upper slit 43, and the lower slit 44 are connected.

[0134] The lower end of the upper panel 21 covers the upper front side of the air vent grille 1, and the upper end of the lower panel 22 covers the lower front side of the air vent grille 1. The lower panel 22, air vent grille 1, and lower panel 22 are connected to form an integral appearance surface, and the slit forms an integral seam around the outer edges of the upper panel 21, air vent grille 1, and lower panel 22. This gives the upper panel 21, air vent grille 1, and lower panel 22 a forward-protruding visual feature. The connection structure between the upper panel 21, air vent grille 1, and lower panel 22 and the main structure of the air conditioner 100 cannot be directly seen from the front, forming a floating visual feature, which makes the air conditioner 100 more three-dimensional. Furthermore, the upper panel 21, air vent grille 1, and lower panel 22 are visually integrated through the overlapping and contour splicing, thereby improving the overall integrity of the front appearance of the air conditioner 100.

[0135] Furthermore, the slit can be used to expand functionality, such as by using it to vent air or install lighting fixtures.

[0136] In some embodiments of this utility model, such as Figure 8 and Figure 17 As shown, the air conditioner 100 includes a main panel 3, which includes a front frame portion 31 and a side panel portion 32. The upper panel 21, the air outlet grille 1, and the lower panel 22 are all located on the front side of the front frame portion 31. The frame area of ​​the front frame portion 31 defines a portion of the appearance of the air conditioner 100 and is arranged around the upper panel 21, the air outlet grille 1, and the lower panel 22 to define an upper slit 43, a long slit 4a, and a lower slit 44 together with the upper panel 21, the air outlet grille 1, and the lower panel 22. There are two side panels 32, which extend backward from the left and right edges of the front frame portion 31, and the upper and lower ends of the side panels 32 are flush with the upper and lower ends of the front frame portion 31, respectively. The side panels 32 define a portion of the appearance of the air conditioner 100.

[0137] The main panel 3 includes a front frame portion 31 and a side panel portion 32. The front frame portion 31 includes a frame area surrounding the upper panel 21, the air vent grille 1, and the lower panel 22. The frame area defines a portion of the exterior surface of the air conditioner 100. The portion of the frame area above the upper panel 21, together with the upper panel 21, defines an upper slit 43. The portion of the frame area below the lower panel 22, together with the lower panel 22, defines a lower slit 44. The left and right portions of the frame area, together with the upper panel 21, the air vent grille 1, and the lower panel 22, define an elongated slit 4a.

[0138] The front side of the air conditioner 100 is formed by the front frame 31, the upper panel 21, the air outlet grille 1, and the lower panel 22. The upper panel 21, the air outlet grille 1, and the lower panel 22 are visually integrated by the splicing of the outline and the obscuring. The upper panel 21, the air outlet grille 1, and the lower panel 22 have a complete surrounding slit relative to the front frame 31. The upper panel 21, the air outlet grille 1, and the lower panel 22 protrude forward relative to the main panel 3 and the connection structure with the main panel 3 cannot be directly seen from the front. This creates a visual feature that the upper panel 21, the air outlet grille 1, and the lower panel 22 are floating relative to the main panel 3, which makes the air conditioner 100 more three-dimensional.

[0139] like Figure 17 As shown, there are two side panels 32, which extend rearward from the left and right sides of the front frame 31 respectively, and the upper and lower ends of the side panels 32 are flush with the upper and lower ends of the front frame 31 respectively. The side panels 32 define at least a portion of the left and right side exterior surfaces of the air conditioner 100.

[0140] In some embodiments of this utility model, such as Figure 12 and Figure 15 As shown, the upper slit 43 opens forward, and the width Gy of the upper slit 43 in the vertical direction is 2mm-50mm; Figure 12 and Figure 16 As shown, the lower slit 44 opens downwards, and the width Gu of the lower slit 44 in the front-to-back direction is 2mm-50mm, as... Figure 5 and Figure 18 As shown, the long slit 4a opens in the normal direction along the side edge of the air outlet grille 1, and the depth Gt of the long slit 4a in the opening direction is 2mm-50mm.

[0141] The upper slit 43 includes a first slit 41 and a second slit 42 that are connected vertically, such as Figure 5 and Figure 18 As shown, the depth Gt of the second slit 42 formed on the left and right sides of the top plate 21 in the opening direction is 2mm-50mm; Figure 6 and Figure 19 As shown, the depth Gt of the first slit 41 formed on the left and right sides of the air outlet grille 1 in the opening direction is 2mm-50mm; Figure 7 and Figure 20 As shown, the depth Gt of the second slit 42 formed on the left and right sides of the bottom plate 22 in the opening direction is 2mm-50mm.

[0142] The upper panel 21 has an upper slit 43 above it. By opening the upper slit 43 forward, the structure that separates the upper part of the upper panel 21 from the main body of the air conditioner 100 becomes more obvious. Similarly, the lower slit 44 is located below the lower panel 22. The lower slit 44 opens downward so that the lower end of the lower panel 22 is separated from the main body of the air conditioner 100. The long slit 4a is located at the left and right ends of the upper panel 21, the air outlet grille 1 and the lower panel 22. The long slit 4a opens along the normal direction of the side edge of the air outlet grille 1. The side edges of the upper panel 21, the air outlet grille 1 and the lower panel 22 are separated from the main body of the air conditioner 100 in the left and right directions, so that the visual feature of the upper panel 21, the air outlet grille 1 and the lower panel 22 floating relative to the main panel 3 is more prominent.

[0143] The elongated slit 4a opens along the normal direction of the side edge of the air outlet grille 1, and the opening direction of the elongated slit 4a is determined according to the direction of the side edge of the air outlet grille 1. For example, when the air outlet grille 1 extends straight in the left-right direction and the front surface of the air outlet grille 1 is flat, then the elongated slit 4a opens directly forward; another example is... Figure 16 and Figure 19 As shown, when the width direction of the air outlet grille 1 extends in an arc along the left and right direction, and the front surface of the air outlet grille 1 is a curved surface that bulges forward, then the long slit 4a opens towards the front and towards the direction away from the center of the air outlet grille 1; as another example, when the width direction of the air outlet grille 1 extends in an arc along the left and right direction, and the front surface of the air outlet grille 1 is a curved surface that bulges backward, then the long slit 4a opens towards the front and towards the direction close to the center of the air outlet grille 1.

[0144] Optionally, the width Gy of the upper slit 43 in the vertical direction can be 2mm, 5mm, 10mm, 20mm, 50mm, etc.

[0145] Optionally, the width Gu of the lower slit 44 in the front-to-back direction can be 2mm, 4mm, 10mm, 25mm, 50mm, etc.

[0146] Optionally, the depth Gt of the long slit 4a along the opening direction can be 2mm, 8mm, 15mm, 20mm, 50mm, etc.

[0147] In some embodiments of this utility model, such as Figure 17 and Figure 21 As shown, the length direction Y of the air conditioner 100 is vertical, and the width direction X is horizontal. The air conditioner 100 includes a main panel 3, on which an air outlet 33 is formed. The air conditioner 100 has an air duct structure 5 extending to the left and right edges of the air outlet 33, and the air duct structure 5 defines an air duct 51 that communicates with the air outlet 33. Airflow flows through the air duct 51 until it flows out from the air outlet 33.

[0148] like Figure 21 As shown, the air outlet grille 1 is located on the front side of the main panel 3 and covers the air outlet 33. The width of the air outlet grille 1 is smaller than the width of the air outlet 33. The left and right sides of the air outlet grille 1 have edge longitudinal grilles 111 extending in the vertical direction. The left edge of the air outlet 33 and the left edge longitudinal grille 111, and the right edge of the air outlet 33 and the right edge longitudinal grille 111 respectively form a first slit 41 extending in the vertical direction. The first slit 41 is connected to the air duct 51.

[0149] An air outlet grille 1 is installed over the air outlet 33. After the airflow flows out of the air outlet 33, it is guided out through the air outlet grille 1. The width of the air outlet grille 1 is designed to be smaller than the width of the air outlet 33. A first slit 41 extending in the vertical direction is formed between the left edge longitudinal grille 111 of the air outlet grille 1 and the left edge of the air outlet 33. A first slit 41 extending in the vertical direction is also formed between the right edge longitudinal grille 111 of the air outlet grille 1 and the right edge of the air outlet 33. The front side of the first slit 41 is open, and the rear side of the first slit 41 is connected to the air duct 51.

[0150] In this way, the airflow flowing out along the air duct 51 can not only pass through the air outlet grille 1, but also flow out through the first slits 41 on the left and right sides, thereby increasing the air outlet range on the left and right sides and increasing the air volume, which is conducive to achieving a full-area airflow effect.

[0151] In some embodiments of this utility model, such as Figure 21 As shown, the air outlet grille 1 includes a plurality of longitudinal grilles 11 extending vertically and spaced apart horizontally. Two of these longitudinal grilles 11 located on the left and right sides of the air outlet grille 1 are edge longitudinal grilles 111. The distance between the edge longitudinal grilles 111 and the corresponding side edge of the air outlet 33 is greater than the distance between any two adjacent longitudinal grilles 11. Figure 19 and Figure 21 As shown, the edge longitudinal grille 111 includes a straight section 1111 and a bent section 1112 arranged sequentially along the flow direction. The straight section 1111 extends from back to front, and the bent section 1112 is deflected at an obtuse angle relative to the straight section 1111 towards the corresponding side edge near the air outlet 33.

[0152] The straight section 1111 of the left edge longitudinal grille 111 extends from back to front, and the bent section 1112 is deflected relative to the straight section 1111 toward the left edge closer to the air outlet 33. The straight section 1111 of the right edge longitudinal grille 111 extends from back to front, and the bent section 1112 is deflected relative to the straight section 1111 toward the right edge closer to the air outlet 33.

[0153] By designing the edge longitudinal grille 111 to include a straight section 1111 and a bent section 1112, not only can the air guiding effect of the edge longitudinal grille 111 to the left and right be improved, which is beneficial to improving the air outlet range and air volume on the left and right sides, but it can also improve the structural stability and structural strength of the edge longitudinal grille 111. Furthermore, the bent section 1112 extends relative to the straight section 1111 towards the side edge of the air outlet 33, which can block the first slit 41 to a certain extent in the front-back direction, reducing the gap between the air outlet grille 1 and the air outlet 33 as seen from the front, which is beneficial to improving the overall integrity of the air conditioner 100.

[0154] In some embodiments of this utility model, such as Figure 17 As shown, the air conditioner 100 has a vertically oriented cross-flow fan 61, which is located at the inlet of the air duct 51. Figure 21 As shown, the air duct 51 includes a first diffuser section 511 and a second diffuser section 512 along the air outlet direction. The left and right duct walls of the first diffuser section 511 extend in a direction close to each other, while the left and right duct walls of the second diffuser section 512 extend in a direction far apart from each other. The air conditioner 100 includes upper and lower air guide plates 62 at least partially disposed in the first diffuser section 511, and left and right air guide plates 63 at least partially disposed in the second diffuser section 512. The "upper and lower air guide plates 62" refer to air guide plates that can swing up and down to adjust the up and down airflow direction; the "left and right air guide plates 63" refer to air guide plates that can swing left and right to adjust the left and right airflow direction.

[0155] The cross-flow impeller 61 generates airflow. The cross-flow impeller 61 is located at the entrance of the air duct 51. After the airflow is driven into the air duct 51 by the cross-flow impeller 61, it first flows into the first diffuser section 511, then flows into the second diffuser section 512 along the first diffuser section 511, and finally flows out from the air outlet 33.

[0156] The left and right walls of the first diffuser section 511 extend in a direction close to each other, while the left and right walls of the second diffuser section 512 extend in directions far apart from each other. The first diffuser section 511 guides the airflow along its extension direction, while the second diffuser section 512 diffuses the airflow in the left and right directions, thereby increasing the airflow's outlet range in the left and right directions. Thus, the duct 51 is a secondary diffuser, undergoing a sudden expansion in the second diffuser section 512. Compared to a single diffuser channel, this increases the pressure at the outlet 33, which helps reduce noise.

[0157] The first diffuser section 511 is provided with upper and lower air guide plates 62, which can increase the air delivery range in the vertical direction. The second diffuser section 512 is provided with left and right air guide plates 63. The second diffuser section 512 diffuses the airflow in the left and right direction, and the left and right air guide plates 63 can further increase the air delivery range in the left and right direction.

[0158] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the length direction Y of the air conditioner 100 is the vertical direction, and the width direction X is the horizontal direction. The air outlet grille 1 includes a plurality of vertical grilles 11 that extend vertically and are spaced apart horizontally.

[0159] The longitudinal grid bars 11 extend vertically and are spaced apart in the left and right directions. Airflow flows out through the gaps between the multiple longitudinal grid bars 11. The form of the longitudinal grid bars 11 is easy to process and facilitates left and right air guidance through the shape design of the longitudinal grid bars 11.

[0160] In some embodiments of this utility model, such as Figure 22 As shown, at least one of the left and right surfaces of the longitudinal grid bar 11 is a flow-through surface 112. Multiple longitudinal grid bars 11 are provided on both sides of the left and right dividing plane of the air outlet grille 1. The direction of extension of the flow-through surface 112 from back to front relative to the left and right dividing plane is the inclination direction of the flow-through surface 112. The flow-through surface 112 of at least one longitudinal grid bar 11 located on the left side of the left and right dividing plane M is inclined to the left, and the flow-through surface 112 of at least one longitudinal grid bar 11 located on the right side of the left and right dividing plane M is inclined to the right.

[0161] The left and right dividing plane M of the air outlet grille 1 refers to the vertical plane extending from the center of the air outlet grille 1 in the left and right direction and along the front and back direction. Multiple longitudinal gratings 11 are respectively arranged on the left and right sides of the left and right dividing plane M of the air outlet grille 1. At least one of the left and right surfaces of the longitudinal gratings 11 is a flow-through surface 112. The flow-through surface 112 of at least one longitudinal grating 11 located on the left side of the left and right dividing plane M is inclined to the left, thereby facilitating the diffusion of airflow to the left. The flow-through surface 112 of at least one longitudinal grating 11 located on the right side of the left and right dividing plane M is inclined to the right, thereby facilitating the diffusion of airflow to the right, thus increasing the overall air supply range of the air conditioner 100 in the left and right direction.

[0162] Optionally, such as Figure 24 and Figure 25As shown, both the left and right surfaces of the longitudinal grid bar 11 can be flow-through surfaces 112. Both the left and right surfaces of the longitudinal grid bar 11 are inclined as described above, allowing airflow to be guided by both surfaces. Alternatively, one side of the left and right surfaces of the longitudinal grid bar 11 can be a flow-through surface 112, while the other side is not inclined as described above. All of these are within the protection scope of this utility model. It is worth noting that when one side of the left and right surfaces of the longitudinal grid bar 11 is a flow-through surface 112, the left side of the longitudinal grid bar 11 located on the left side of the left-right dividing plane can be a flow-through surface 112, and the right side of the longitudinal grid bar 11 located on the left side of the left-right dividing plane can also be a flow-through surface 112. Similarly, the flow-through surface 112 of the longitudinal grid bar 11 located on the right side of the left-right dividing plane can also be either the left or right side.

[0163] In some embodiments of this utility model, such as Figure 22 , Figure 23 , Figure 24 and Figure 25 As shown, multiple adjacent longitudinal bars 11 form a parallel group 11a, and the flow surfaces 112 of all longitudinal bars 11 in the same parallel group 11a are parallel. Thus, the air guiding direction of the longitudinal bars 11 in multiple parallel groups 11a is consistent, which can improve the air guiding effect. Furthermore, by making the flow surfaces 112 of all longitudinal bars 11 in the same parallel group 11a parallel, the design and manufacturing process can be simplified.

[0164] In some embodiments of this utility model, such as Figure 22 and Figure 23 As shown, one of the parallel groups 11a is the central group 11a1. The flow surface 112 of each longitudinal bar 11 in the central group 11a1 extends from back to front parallel to the left and right dividing plane. The central group 11a1 has at least one longitudinal bar 11 arranged on each of the left and right sides of the left and right dividing plane; as shown Figure 22 , Figure 24 and Figure 25 As shown, multiple parallel groups 11a are arranged on the left and right sides of the central group 11a1. The parallel groups 11a located on both sides of the central group 11a1 are inclined groups 11a2. Among the multiple inclined groups 11a2 on the same side of the central group 11a1, the inclined group 11a2 further away from the central group 11a1 has a larger inclination angle of the flow surface 112 of the longitudinal grid bar 11.

[0165] The flow surface 112 of each longitudinal bar 11 of the central group 11a1 extends from back to front parallel to the left-right dividing plane M, and at least one of the longitudinal bars 11 of the central group 11a1 is located on the left and right sides of the left-right dividing plane M. The longitudinal bars 11 of the central group 11a1 are used to guide the airflow forward, which helps to increase the forward air delivery distance of the air conditioner 100.

[0166] Multiple inclined groups 11a2 are respectively arranged on the left and right sides of the central group 11a1, thereby increasing the overall air supply range of the air conditioner 100 in the left and right directions. Among the multiple inclined groups 11a2 located to the left of the central group 11a1, the inclined group 11a2 further away from the central group 11a1 has a larger inclination angle of the flow surface 112 of the longitudinal grid 11, which is conducive to the airflow diffusing to the left. Similarly, among the multiple inclined groups 11a2 located to the right of the central group 11a1, the inclined group 11a2 further away from the central group 11a1 has a larger inclination angle of the flow surface 112 of the longitudinal grid 11, which is conducive to the airflow diffusing to the right, thereby increasing the overall air supply range of the air conditioner 100 in the left and right directions.

[0167] In some specific embodiments of this utility model, such as Figure 22 , Figure 24 and Figure 25 As shown, in the two inclined groups 11a2 located to the right of the central group 11a1, the inclination angle b of the flow surface 112 of the longitudinal grid bar 11 in the inclined group 11a2 that is closer to the central group 11a1 is smaller than the inclination angle c of the flow surface 112 of the longitudinal grid bar 11 in the inclined group 11a2 that is farther away from the central group 11a1.

[0168] In some embodiments of this utility model, such as Figures 23-25 As shown, the dimension of the longitudinal grid bar 11 from the air inlet end to the air outlet end is the flow dimension. Among the multiple inclined groups 11a2 on the same side of the central group 11a1, the flow dimension of the longitudinal grid bar 11 in the inclined group 11a2 that is farther away from the central group 11a1 is smaller, and the thickness of the longitudinal grid bar 11 in the inclined group 11a2 that is farther away from the central group 11a1 is smaller.

[0169] The flow-through dimension refers to the length of the longitudinal grille 11 from the air inlet to the air outlet. The longitudinal grille 11 in the inclined group 11a2 tilts to the left or right along the front-to-back direction, which guides the airflow from front to back but also increases wind resistance. Furthermore, the tilt angle of the flow-through surface area 112 of the longitudinal grille 11 in the inclined group 11a2, which is further away from the central group 11a1, is larger, resulting in greater wind resistance. Therefore, by reducing the flow-through dimension and thickness of the longitudinal grille 11 in the inclined group 11a2, and making the flow-through dimension and thickness of the longitudinal grille 11 in the inclined group 11a2 smaller the further away from the central group 11a1, it is possible to maintain the left-right airflow guidance of the inclined group 11a2 while reducing wind resistance and improving the air supply efficiency of the air conditioner 100.

[0170] In some embodiments of this utility model, such as Figure 23 and Figure 30As shown, the longitudinal grid bar 11 in the central group 11a1 has the largest flow dimension Wa, and the longitudinal grid bar 11 in the central group 11a1 has the largest thickness Ta; in the two inclined groups 11a2 located to the right of the central group 11a1, as... Figure 24 and Figure 33 As shown, the overcurrent dimension Wb of the longitudinal grid bar 11 in the inclined group 11a2, which is relatively closer to the central group 11a1, is less than Wa, and the thickness Tb of the longitudinal grid bar 11 in the inclined group 11a2, which is relatively closer to the central group 11a1, is less than Ta; as Figure 25 and Figure 36 As shown, the flow dimension Wc of the longitudinal grid bar 11 in the inclined group 11a2, which is relatively far from the central group 11a1, is less than Wb, and the thickness Lc of the longitudinal grid bar 11 in the inclined group 11a2, which is relatively far from the central group 11a1, is less than Lb.

[0171] In some embodiments of this utility model, such as Figure 26 , Figure 27 and Figure 28 As shown, there are five parallel groups 11a, one of which is the central group 11a1, and four of which are inclined groups 11a2. The flow dimension of the longitudinal grid bar 11 is 3-30mm.

[0172] The central group 11a1 directs the airflow forward, which helps to increase the forward air delivery distance of the air conditioner 100. Two inclined groups 11a2 are respectively arranged on the left and right sides of the central group 11a1, which helps to diffuse the airflow to the left and right sides respectively, increasing the overall air delivery range of the air conditioner 100 in the left and right directions. The central group 11a1 and the inclined groups 11a2 achieve the effect of uniform airflow distribution and guidance, transforming the single-direction, small-angle airflow blown out of the duct 51 into multi-directional, large-angle scattered airflow.

[0173] In some embodiments of this utility model, such as Figure 26 and Figure 28 As shown, among the inclined groups 11a2 located on the left and right sides of the central group 11a1, the inclined group 11a2 that is relatively closer to the central group 11a1 is the first inclined group 11a21, and the one that is relatively farther away from the central group 11a1 is the second inclined group 11a22. The two first inclined groups 11a21 are symmetrically arranged along the left and right dividing plane M, and the structural features of the two first inclined groups 11a21 are mirror images of each other. The two second inclined groups 11a22 are symmetrically arranged along the left and right dividing plane M, and the structural features of the two second inclined groups 11a22 are mirror images of each other.

[0174] like Figure 26As shown, the lines with arrows represent the airflow directions of the five parallel groups 11a. The airflow angle between the adjacent central group 11a1 and the first inclined group 11a21 on the right is θab°, the airflow angle between the first inclined group 11a21 on the right and the second inclined group 11a22 on the right is θbc°, the airflow angle between the adjacent central group 11a1 and the first inclined group 11a21 on the left is θad°, and the airflow angle between the first inclined group 11a21 on the left and the second inclined group 11a22 on the left is θde°.

[0175] The longitudinal bars 11 of different central groups 11a1 face different angles. When a small-angle wind blows from the air duct 51 to the air outlet grille 1, the longitudinal bars 11 of different central groups 11a1 will guide and disperse the small-angle wind into winds of different angles, which will achieve the effect of evenly scattering the wind and softening the wind feeling, making the heat output more uniform and the wind feeling softer. The human body will not feel a strong wind, but will feel cool or warm, and the comfort will be greatly improved.

[0176] In some embodiments of this utility model, such as Figure 23 , Figure 24 and Figure 25 As shown, the longitudinal grid bar 11 includes an inlet section 113 and an outlet section 114 arranged sequentially along the flow direction. The width of the inlet section 113 gradually decreases against the flow direction, while the width of the outlet section 114 remains uniform along the flow direction.

[0177] The inlet end features a conical air guide structure, which achieves uniform airflow distribution and guidance, transforming the single-direction, small-angle airflow blowing out of the air duct 51 into multi-direction, large-angle scattered airflow, resulting in more uniform heat output and a smoother airflow. The outlet section 114 has a straight structure with a uniform and constant width, which allows the airflow to be stably delivered along the extension direction of the outlet section 114, reducing turbulence and improving airflow fluidity.

[0178] In some embodiments of this utility model, such as Figure 23 , Figure 24 and Figure 25 As shown, the outer end faces of the exit section 114 are coplanar, sharing the same plane or the same arc surface.

[0179] In some embodiments of this utility model, such as Figure 4 and Figure 27As shown, the air outlet grille 1 also includes a plurality of horizontal grille bars 12 extending in the left-right direction and spaced apart in the up-down direction. The vertical grille bars 11 of the central group 11a1 include connecting sections 115 and cutting sections 116 arranged vertically. The connecting section 115 is located on the side of the cutting section 116 near the horizontal grille bars 12. The rear end face of the cutting section 116 is forward relative to the rear end face of the connecting section 115, and the distance Wq between the rear end face of the cutting section 116 and the rear end face of the connecting section 115 in the front-back direction is 1mm-29mm.

[0180] The central group 11a1 directs the airflow forward, while the inclined group 11a2 diffuses the airflow to the left and right sides respectively. By providing a reduction section 116 on the longitudinal bars 11 of the central group 11a1, the size of the longitudinal bars 11 in the front-to-back direction is reduced, which can reduce wind resistance and facilitate the dispersion of airflow towards the inclined group 11a2. The longitudinal bars 11 of the central group 11a1 are provided with a connecting section 115. The connecting section 115 has a large size in the front-to-back direction, which can improve the connection strength between the longitudinal bars 11 and the transverse bars 12, and help improve the structural stability of the longitudinal bars 11.

[0181] Optionally, the distance Wq between the rear end face of the cutting section 116 and the rear end face of the connecting section 115 in the front-rear direction can be 1mm, 3mm, 5mm, 15mm and 29mm, etc.

[0182] In some embodiments of this utility model, there are five parallel groups 11a, one of which is a central group 11a1, and four of which are inclined groups 11a2. Among the inclined groups 11a2 located on the left and right sides of the central group 11a1, the inclined group 11a2 that is relatively closer to the central group 11a1 is the first inclined group 11a21, and the one that is relatively farther away from the central group 11a1 is the second inclined group 11a22. The two first inclined groups 11a21 are symmetrically arranged along the left and right mid-plane M, and the structural features of the two first inclined groups 11a21 are mirror images of each other. The two second inclined groups 11a22 are symmetrically arranged along the left and right mid-plane M, and the structural features of the two second inclined groups 11a22 are mirror images of each other.

[0183] Figures 29-31 For the longitudinal grating 11 of the central group 11a1, Figures 32-34 For the longitudinal grating strip 11 of the first inclined group 11a21, Figures 35-37 The thicknesses Ta of the longitudinal grid strips 11 of the central group 11a1, Tb of the longitudinal grid strips 11 of the first inclined group 11a21, and the thicknesses Tc of the longitudinal grid strips 11 of the second inclined group 11a22 satisfy the following: 3mm≤Ta≤30mm, 3mm≤Tb≤30mm, and 3mm≤Tc≤30mm.

[0184] In some embodiments of this utility model, such as Figure 38and Figure 39 As shown, the longitudinal grille 11 extends from the upper end of the air outlet grille 1 to the lower end of the air outlet grille 1, and the front surface of the longitudinal grille 11 constitutes the front surface of the air outlet grille 1; wherein, the spacing Js between adjacent longitudinal grille 11 is 5mm to 90mm; and / or, the front surfaces of all longitudinal grille 11 are coplanar with the same plane or the same arc surface.

[0185] The small spacing between adjacent vertical bars 11 prevents users from reaching their hands into the air conditioner 100 through the air vent grille 1.

[0186] Optionally, the spacing Js between adjacent longitudinal bars 11 can be 5mm, 20mm, 50mm, 60mm, 80mm, 90mm, etc.

[0187] All the front surfaces of the longitudinal grilles 11 are coplanar, on the same plane or the same arc surface, giving the longitudinal grilles 11 a strong sense of integrity and improving their visual appeal and airflow guiding effect.

[0188] In some embodiments of this utility model, such as Figure 38 and Figure 39 As shown, the air outlet grille 1 includes an inner grille 1a and an outer grille 1b. The inner grille 1a includes an inner grille bar 1a1, and the outer grille 1b includes an outer grille bar 1b1. The outer grille bar 1b1 extends in a different direction than the inner grille bar 1a1. The outer grille bar 1b1 is integrally connected to the inner grille bar 1a1 or is connected separately. At least a portion of the outer grille bar 1b1 protrudes from the front side of the inner grille bar 1a1, and the front surface of the outer grille bar 1b1 constitutes the front surface of the air outlet grille 1.

[0189] By connecting the outer grille 1b1 and the inner grille 1a1 with different extending directions to form the air outlet grille 1, and the inner grille 1a1 and the outer grille 1b1 interlacing to form a grid shape, the structural strength of the air outlet grille 1 can be improved. Furthermore, since the outer grille 1b1 is convex, it is convenient to process the front surface of the outer grille 1b1, which also makes it convenient to process the appearance surface of the air outlet grille 1.

[0190] In some embodiments of this utility model, such as Figures 39-43 As shown, the angle ∠hs between the extension direction of the outer grid strip 1b1 and the extension direction of the inner grid strip 1a1 is 10°-90°; there are multiple inner grid strips 1a1, all of which are arranged in parallel, or they are divided into multiple groups, and the inner grid strips 1a1 in each group are arranged in parallel; there are multiple outer grid strips 1b1, all of which are arranged in parallel, or they are divided into multiple groups, and the outer grid strips 1b1 in each group are arranged in parallel.

[0191] The parallel arrangement of inner grid bars 1a1 means that the extension direction of multiple inner grid bars 1a1 is consistent, and the parallel arrangement of outer grid bars 1b1 means that the extension direction of multiple outer grid bars 1b1 is consistent.

[0192] All the inner bars 1a1 of the inner grille 1a can be arranged in parallel, or they can be divided into multiple groups, with the inner bars 1a1 of each group arranged in parallel; all the outer bars 1b1 of the outer grille 1b can be arranged in parallel, or they can be divided into multiple groups, with the outer bars 1b1 of each group arranged in parallel, thus allowing for the design of air outlet grilles 1 with various mesh shapes.

[0193] Optionally, the angle ∠hs formed by the extension direction of the outer grid strip 1b1 and the extension direction of the inner grid strip 1a1 can be 10°, 35°, 45°, 60°, 90°, etc.

[0194] like Figure 40 As shown in Embodiment 1, all inner grid bars 1a1 are arranged in parallel, and all outer grid bars 1b1 are arranged in parallel. The inner grid bars 1a1 extend in the horizontal direction, and the outer grid bars 1b1 extend in the vertical direction. The angle ∠hs formed by the extension direction of the outer grid bars 1b1 and the extension direction of the inner grid bars 1a1 is 90°.

[0195] like Figure 41 As shown in Embodiment 2, all inner grid strips 1a1 are arranged in parallel, and all outer grid strips 1b1 are arranged in parallel. The inner grid strips 1a1 extend in the horizontal direction, and the angle ∠hs formed between the extension direction of the outer grid strips 1b1 and the extension direction of the inner grid strips 1a1 is 45°.

[0196] like Figure 42 As shown in Embodiment 3, all inner grid strips 1a1 are arranged in parallel, and all outer grid strips 1b1 are arranged in parallel. The angle ∠hs formed by the extension direction of the outer grid strip 1b1 and the extension direction of the inner grid strip 1a1 is 10°.

[0197] like Figure 43 As shown in Embodiment 3, all inner grid strips 1a1 are arranged in parallel, and outer grid strips 1b1 are divided into multiple groups with the inner grid strips 1a1 as the boundary. The outer grid strips 1b1 in each group are arranged in parallel, and the angle ∠hs formed by the extension direction of the outer grid strip 1b1 and the extension direction of the inner grid strip 1a1 is 45°.

[0198] In some embodiments of this utility model, such as Figure 39 As shown, the spacing Jh between adjacent inner grille bars 1a1 is more than twice the spacing Js between adjacent outer grille bars 1b1. The front surface of the outer grille bars 1b1 constitutes the main element of the appearance of the air outlet grille 1, while the inner grille bars 1a1 serve to support the outer grille bars 1b1, improve the structural stability of the outer grille bars 1b1, and reduce the deformation of the outer grille bars 1b1. Therefore, there are more outer grille bars 1b1 arranged relatively closely. There are fewer inner grille bars 1a1 arranged relatively loosely, which reduces the obstruction to airflow and helps to improve the air guiding effect.

[0199] In some embodiments of this utility model, the spacing Js between adjacent outer grid bars 1b1 is 5mm-90mm, and the spacing Jh between adjacent inner grid bars 1a1 is 5mm-500mm.

[0200] Optionally, the spacing Js between adjacent outer grid bars 1b1 can be 5mm, 10mm, 50mm, 60mm, 90mm, etc.

[0201] Optionally, the spacing Jh between adjacent inner bars 1a1 can be 5mm, 80mm, 100mm, 200mm, 500mm, etc.

[0202] In some embodiments of this utility model, the protrusion height of the outer grid bar 1b1 protruding from the inner grid bar 1a1 is 0.5mm-50mm.

[0203] The inner grid 1a1 serves as a supporting structure, and its main function is to ensure overall strength and improve the efficiency of mold injection. It is not a major appearance element, and its visual visibility should be minimized. Therefore, the outer grid 1b1 is designed to protrude at least partially from the front of the inner grid 1a1, forming a forward-protruding height difference.

[0204] Optionally, the protrusion height of the outer grid bar 1b1 protruding forward from the inner grid bar 1a1 is 0.5mm, 1mm, 5mm, 10mm, 25mm, 50mm, etc.

[0205] In some embodiments of this utility model, such as Figure 38 and Figure 44 As shown, the outer grille 1b1 is a longitudinal grille 11 extending along the length of the air outlet grille 1, and the inner grille 1a1 is a horizontal grille 12 extending along the width of the air outlet grille 1. The horizontal grilles 12 located at both ends of the length of the air outlet grille 1 are edge horizontal grilles 121, as shown. Figure 47 and Figure 50 As shown, the protrusion height Ge of the vertical grating 11 protruding from the edge horizontal grating 121 is 0.5mm-50mm, as... Figure 52 As shown, the protrusion height Gw of the vertical grating 11 protruding from the other horizontal grating 12 is 1mm-20mm.

[0206] The edge horizontal grille 121 is located at both ends of the length of the air outlet grille 1. As the edge component of the air outlet grille 1, the edge horizontal grille has a stronger supporting effect than the other horizontal grilles. Therefore, the protrusion height Ge of the vertical grille 11 protruding from the edge horizontal grille 121 can be larger, which can improve the connection strength between the edge horizontal grille 121 and the vertical grille 11 and improve the structural stability of the long edge of the air outlet grille 1.

[0207] Optionally, the protrusion height Ge of the longitudinal grid strip 11 protruding from the edge transverse grid strip 121 is 0.5mm, 2mm, 20mm, 40mm, 50mm, etc.

[0208] Optionally, the protrusion height Gw of the longitudinal grating 11 protruding from the other transverse grating 12 is 1mm, 5mm, 10mm, 15mm, 20mm, etc.

[0209] In some embodiments of this utility model, such as Figure 57 As shown, the edge horizontal grille 121 protrudes forward more than the other horizontal grille 12, which can improve the connection strength between the edge horizontal grille 121 and the vertical grille 11 and improve the structural stability of the long edge of the air outlet grille 1.

[0210] In some embodiments of this utility model, the front surface of the outer grid strip 1b1 has a decorative layer, which is at least one of a hot stamping layer, a UV layer, a spraying layer, and a transfer layer.

[0211] At least a portion of the outer grille 1b1 protrudes from the front side of the inner grille 1a1. The front surface of the outer grille 1b1 constitutes the front surface of the air outlet grille 1. The main appearance of the air outlet grille 1 is a regular mesh grille structure. The arrangement of the outer grille 1b1 is regular and occupies a large projected area, which makes it highly recognizable in terms of appearance. It can also be used as an appearance design element. Differentiated style designs can be made by applying different surface treatment processes and colors to the front surface of the outer grille 1b1, such as hot stamping, UV coating, spraying, transfer printing, etc. Differentiated style designs can also be made by partially disassembling the structure.

[0212] In some embodiments of this utility model, such as Figure 44 As shown, the air outlet grille 1 includes edge horizontal grille 121, edge vertical grille 111, and end fixing structure 13. The edge horizontal grille 121 extends along the width direction of the air outlet grille 1 and is located at both ends of the length of the air outlet grille 1. The edge vertical grille 111 extends along the length direction of the air outlet grille 1 and is located on both sides of the width of the air outlet grille 1. The end fixing structure 13 is provided at both ends of the length of the air outlet grille 1 for installation of the air outlet grille 1.

[0213] The outer frame of the air outlet grille 1 is a quadrilateral structure, and the main frame is composed of two edge longitudinal grilles 111 and two edge horizontal grilles 121, which improves the structural stability of the air outlet grille 1.

[0214] End fixing structures 13 are provided at both ends of the length of the air outlet grille 1, i.e., on the edge horizontal grille 121, for the installation of the air outlet grille 1. Connecting the two ends of the length of the air outlet grille 1 to the main structure of the air conditioner 100 can improve the connection stability of the air outlet grille 1.

[0215] In some embodiments of this utility model, such as Figure 46 and Figure 47As shown, the length direction of the air outlet grille 1 is vertical, and a top fixing structure 131 is provided on the upper edge horizontal grille 121, as shown. Figure 49 and Figure 50 As shown, a bottom fixing structure 132 is provided on the lower edge horizontal grid strip 121.

[0216] In some embodiments of this utility model, such as Figure 51 and Figure 52 As shown, the air outlet grille 1 includes a plurality of longitudinal grille bars 11 extending along the length direction of the air outlet grille 1 and spaced apart along the width direction of the air outlet grille 1. The longitudinal grille bars 11 located at the two wide edges are called edge longitudinal grille bars 111. The flow-through size and / or thickness of the edge longitudinal grille bars 111 is greater than the flow-through size and / or thickness of at least one other longitudinal grille bar 11. The wider flow-through size of the edge longitudinal grille bars 111 can improve the air guiding effect and improve the structural stability of the air outlet grille 1. The greater thickness of the edge longitudinal grille bars 111 can also improve the structural stability of the air outlet grille 1.

[0217] like Figure 51 and Figure 57 As shown, the air outlet grille 1 includes a plurality of horizontal gratings 12 extending along the width direction and spaced apart along the length direction of the air outlet grille 1. The horizontal gratings 12 located at the two long edges are edge horizontal gratings 121, and the width and / or thickness of the edge horizontal gratings 121 is greater than the width and / or thickness of at least one of the other horizontal gratings 12. The width of the horizontal grating 12 refers to its dimension along the vertical direction. The wider edge horizontal gratings 121 improves the structural stability of the air outlet grille 1. The greater thickness of the edge horizontal gratings 121 also improves the structural stability of the air outlet grille 1.

[0218] In some embodiments of this utility model, such as Figure 51 As shown, the length direction of the air outlet grille 1 is vertical, and the horizontal grille 12 includes an upper edge horizontal grille 121 and a lower edge horizontal grille 121, as shown. Figure 54 and Figure 57 As shown, the width W1 of the upper edge horizontal grille 121 ranges from 5mm to 60mm. Figure 55 and Figure 57 As shown, the width W2 of the lower edge horizontal grille 121 ranges from 5mm to 60mm. Figure 52 and Figure 57 As shown, the width W3 of the remaining horizontal bars 12 satisfies: 2mm≤W3≤W1, and also satisfies: 2mm≤W3≤W2.

[0219] In some embodiments of this utility model, such as Figure 44 and Figure 56As shown in the figure, the horizontal grid bars 12 include a central horizontal grid bar 122 located in the central area in the length direction of the air outlet grille 1. The width and / or thickness of the central horizontal grid bar 122 is greater than that of any horizontal grid bar 12 other than the edge horizontal grid bars 121. The width and / or thickness of the edge horizontal grid bars 121 is greater than that of any horizontal grid bar 12 other than the central horizontal grid bar 122. The air outlet grille 1 further includes a central limiting structure 14. The central limiting structure 14 is provided at the rear side of the central horizontal grid bar 122 and is in limiting cooperation with the carrier member of the air outlet grille 1.

[0220] A central limiting structure 14 is provided at the rear side of the central horizontal grid bar 122. The air outlet grille 1 is not only installed at both ends of its length but also installed at the middle part, which can improve the installation stability of the air outlet grille 1.

[0221] Moreover, the width of the central horizontal grid bar 122 is relatively wide. The two edge vertical grid bars 111 and the two edge horizontal grid bars 121 serve as the main outer frame structure and together with the central horizontal grid bar 122 in the middle form a stable "day" - shaped frame structure, which plays a role in maintaining the overall structural stability. Therefore, the width and thickness dimensions of these five grid bars are wider than those of other grid bars, and their strength is also better.

[0222] In some embodiments of the present utility model, the horizontal grid bars 12 located at the two long - side edges are edge horizontal grid bars 121. The width of the edge horizontal grid bars 121 is greater than the thickness of any horizontal grid bar 12 other than the central horizontal grid bar 122. The horizontal grid bar 12 located in the central area in the length direction of the air outlet grille 1 is the central horizontal grid bar 122. The thickness of the central horizontal grid bar 122 is greater than the thickness of any horizontal grid bar 12 other than the edge horizontal grid bars 121, which can improve the structural stability of the air outlet grille 1.

[0223] In some embodiments of the present utility model, as Figure 51 shown, the length direction of the air outlet grille 1 is the up - down direction. The horizontal grid bars 12 include edge horizontal grid bars 121 located at the upper end and edge horizontal grid bars 121 located at the lower end. As Figure 47 and Figure 57 shown, the thickness T1 of the edge horizontal grid bar 121 located at the upper end ranges from 5 mm to 60 mm. As Figure 50 and Figure 57 shown, the thickness T2 of the edge horizontal grid bar 121 located at the lower end ranges from 5 mm to 60 mm. As Figure 57 shown, the thickness T3 of the central horizontal grid bar 122 ranges from 5 mm to 60 mm. As Figure 57 shown, the thickness T5 of the remaining horizontal grid bars 12 satisfies: T5 ≤ T1, T5 ≤ T2 and T5 ≤ T3.

[0224] The existing air conditioner panel assembly structure is mainly based on louvers + air guide plate + door opening structure or louvers + roller structure + door opening structure. During operation, it can only swing left and right within a fixed air swing range to deliver air. Its air delivery mode is single and uneven, resulting in inconsistent cooling / heating speeds at different angles within the same distance range in the actual use environment, and the comfort of the human body needs to be improved.

[0225] To address the limitations of existing air conditioner panel components, a floating-style air outlet grille structure is designed. This structure consists of a mesh-like grille component with an arc or flat cross-section along its length, placed on the outermost side of the air outlet. This design combines aesthetic appeal with effective and uniform airflow distribution.

[0226] 1. As an exterior decorative component fixed to the panel assembly, its unique grid-like appearance, the grille surface can be a bare part without surface treatment or a surface treatment such as hot stamping, spraying, UV coating, etc. It can also be a structural decorative component in the form of a disassembled part, all of which have a good style recognition. In addition, with the concave or convex shape treatment of the panel assembly, the appearance style is highly expandable.

[0227] 2. The air guiding mechanism inside the air duct of the panel assembly has various forms, usually consisting of a combination of louvers, air guide plates, door opening and closing mechanisms, and roller drum structures. However, their air outlet range is all at a fixed angle and the angle is relatively small. Now, a grid-shaped air outlet grille structure is designed and placed on the outermost side of the air outlet of the air duct. The uneven small-angle air formed in the air duct 51 by the air guiding action of louvers, air guide plates, and roller drum is transformed by the air outlet grille 1 into a large-angle air with a larger radiation angle and more uniformity. This makes the cooling / heating rate of different angles within the space more consistent, avoids the problem of uneven heating and cooling in different areas of the space, and improves the user's comfort experience.
