[0016] In some embodiments, the second wall portion includes a first curved segment, the first curved segment extending from back to front having a length greater than 1 / 2 of the second wall portion extending from back to front. The first curved segment is formed as a curve protruding from the line connecting the front and rear ends of the second wall portion toward a direction away from the second air duct wall, so as to form an air-avoidance space between the extension lines of the second wall portion and the first wall portion.

[0061] 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.

[0062] 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.

[0063] Hereinafter, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present invention will be described.

[0064] like Figures 1-3As shown, the air conditioner 100 extends vertically and has an air outlet 111 on its front side. The air conditioner 100 includes: a cross-flow fan 2, an air duct structure 3, a first air guide plate component 4, and an air outlet grille 5. The axis of the cross-flow fan 2 extends vertically. The air duct structure 3 includes a left air duct wall 31 extending from the cross-flow fan 2 to the left edge 111a of the air outlet, and a right air duct wall 32 extending from the cross-flow fan 2 to the right edge 111b of the air outlet. The first air guide plate component 4 includes a first air guide plate 41 disposed between the left air duct wall 31 and the right air duct wall 32. The first air guide plate 41 is rotatable about a vertical axis extending vertically. The air outlet grille 5 is disposed at the air outlet 111 and is located in front of the first air guide plate 41 (i.e., on the side facing the user). Wherein, the width L of the air outlet 111 in the left-right direction is greater than or equal to 70% of the width W of the air conditioner 100 in the left-right direction; and / or, the width L of the air outlet 111 in the left-right direction is more than twice the diameter D of the cross-flow fan 2.

[0065] The statement that the left duct wall 31 extends from the cross-flow impeller 2 to the left edge 111a of the air outlet means that the extension trend of the left duct wall 31 is from the cross-flow impeller 2 to the left edge 111a of the air outlet, rather than requiring the left duct wall 31 to extend from the surface of the cross-flow impeller 2. The same applies to the right side, which will not be elaborated here.

[0066] Among them, "the width L of the air outlet 111 in the left and right direction is greater than or equal to 70% of the width W of the air conditioner 100 in the left and right direction". For example, the width L of the air outlet 111 in the left and right direction can be 0.7 times, 0.75 times, 0.8 times, 0.85 times, 0.9 times, 0.95 times, etc. of the width W of the air conditioner 100 in the left and right direction.

[0067] Among them, "the width L of the air outlet 111 in the left and right direction is more than twice the diameter D of the cross-flow impeller 2". For example, the width L of the air outlet 111 in the left and right direction is 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3 times, etc. of the diameter D of the cross-flow impeller 2.

[0068] When the width L of the air outlet 111 in the left-right direction is greater than or equal to 70% of the width W of the air conditioner 100 in the left-right direction, it indicates that the width of the air outlet 111 in the left-right direction is relatively large. The air duct structure 3 is set to include a left air duct wall 31 extending from the cross-flow fan 2 to the left edge 111a of the air outlet, and a right air duct wall 32 extending from the cross-flow fan 2 to the right edge 111b of the air outlet. This allows the air blown by the cross-flow fan 2 to be fully blown out of the air outlet 111, with a large air outlet range. Furthermore, the first air guide plate 41 set on the air outlet path facilitates the adjustment and rectification of the air outlet angle in the left-right direction. Moreover, for this case where the air outlet 111 is large, the air outlet grille 5 set on the front side of the first air guide plate 41 can play a certain degree of protection while meeting the air outlet requirements.

[0069] When the width L of the air outlet 111 in the left-right direction is more than twice the diameter D of the cross-flow impeller 2, it indicates that the width of the air outlet 111 in the left-right direction is relatively large. The air duct structure 3 is set to include a left air duct wall 31 extending from the cross-flow impeller 2 to the left edge 111a of the air outlet, and a right air duct wall 32 extending from the cross-flow impeller 2 to the right edge 111b of the air outlet. This allows the air blown by the cross-flow impeller 2 to be fully blown out of the air outlet 111, with a large air outlet range. Furthermore, the first air guide plate 41 set on the air outlet path facilitates the adjustment and rectification of the air outlet angle in the left-right direction. Moreover, for this case where the air outlet 111 is large, the air outlet grille 5 set in front of the first air guide plate 41 can play a certain degree of protective role while meeting the air outlet requirements.

[0070] Specifically, when the width L of the air outlet 111 in the left-right direction is greater than or equal to 70% of the width W of the air conditioner 100 in the left-right direction, and the width L of the air outlet 111 in the left-right direction is more than twice the diameter D of the cross-flow fan 2, it indicates that the width of the air outlet 111 in the left-right direction is relatively large. The air duct structure 3 is set to include a left air duct wall 31 extending from the cross-flow fan 2 to the left edge 111a of the air outlet, and a right air duct wall 32 extending from the cross-flow fan 2 to the right edge 111b of the air outlet. This allows the air blown by the cross-flow fan 2 to be fully blown out of the air outlet 111, resulting in a large air outlet range. Furthermore, the first air guide plate 41 set on the air outlet path facilitates the adjustment and rectification of the air outlet angle in the left-right direction. Moreover, for this case where the air outlet 111 is large, the air outlet grille 5 set on the front side of the first air guide plate 41 can provide a certain degree of protection while meeting the air outlet requirements.

[0071] In some embodiments, combined with Figure 4 and Figure 5The air outlet grille 5 includes a plurality of vertical grilles 51 extending in the vertical direction and spaced apart in the horizontal direction. A plurality of vertical grilles 51 are respectively provided on both sides of the left and right dividing plane S of the air outlet 111. The air guiding surface 510 of at least one vertical grille 51 located on the left side of the left and right dividing plane S extends from back to front at an angle to the left relative to the left and right dividing plane S. The air guiding surface 510 of at least one vertical grille 51 located on the right side of the left and right dividing plane S extends from back to front at an angle to the right relative to the left and right dividing plane S.

[0072] The term "the left and right dividing plane S of the air outlet 111" refers to a vertical plane extending from the center of the air outlet 111 in the left-right direction and along the front-back direction. "Multiple vertical gratings 51 are respectively arranged on both sides of the left and right dividing plane S of the air outlet 111" means that multiple vertical gratings 51 are arranged on the left side of the left and right dividing plane S, and multiple vertical gratings 51 are also arranged on the right side of the left and right dividing plane S. "The air guiding surface 510 of the vertical grating 51" means that the vertical grating 51 extends in the vertical direction, and both the left and right surfaces of the vertical grating 51 extend approximately from back to front to allow airflow to follow them, thus at least one of the left and right surfaces of the vertical grating 51 serves as an air guiding surface 510.

[0073] Therefore, by setting the air guide surface 510 of at least one vertical bar 51 located on the left side of the left-right dividing plane S to extend from back to front relative to the left-right dividing plane S at an angle to the left, it is beneficial for the airflow to diffuse to the left. The air guide surface 510 of at least one vertical bar 51 located on the right side of the left-right dividing plane S to extend from back to front relative to the left-right dividing plane S at an angle to the right, it is beneficial for the airflow to diffuse to the right, thereby increasing the overall air supply range of the air conditioner 100 in the left-right direction.

[0074] For example, the width L of the air outlet 111 in the left-right direction is greater than or equal to 90% of the width W of the air conditioner 100 in the left-right direction, indicating that the width of the air outlet 111 in the left-right direction is relatively larger. The air duct structure 3 is set to include a left air duct wall 31 extending from the cross-flow fan 2 to the left edge 111a of the air outlet, and a right air duct wall 32 extending from the cross-flow fan 2 to the right edge 111b of the air outlet. This allows the air blown by the cross-flow fan 2 to be fully blown out of the air outlet 111, with a large air outlet range. Furthermore, the first air guide plate 41 set on the air outlet path facilitates the adjustment and rectification of the air outlet angle in the left-right direction. Moreover, for this case where the air outlet 111 is large, the air outlet grille 5 set in front of the first air guide plate 41 can provide a certain degree of protection while meeting the air outlet requirements.

[0075] In some embodiments, combined with Figure 4Multiple adjacent vertical gratings 51 form a parallel group 53, and the air guiding surfaces 510 of all vertical gratings 51 in the same parallel group 53 are parallel. Therefore, by setting the air guiding surfaces 510 of multiple adjacent vertical gratings 51 to be parallel, the design and manufacturing process can be simplified. Of course, this application is not limited to this. For example, in other embodiments of this application, the air guiding surfaces 510 of any two vertical gratings 51 can be non-parallel. For instance, the further away from the left and right dividing plane S of the air outlet 111, the greater the angle of inclination of the air guiding surface 510 relative to the left and right dividing plane S.

[0076] In some embodiments, multiple parallel groups 53 are provided on the left side of the left-right dividing plane S, and the vertical gratings 51 in the parallel groups 53 closer to the left edge 111a of the air outlet have a larger inclination angle. Similarly, multiple parallel groups 53 are provided on the right side of the left-right dividing plane S, and the vertical gratings 51 in the parallel groups 53 closer to the right edge 111b of the air outlet have a larger inclination angle. Here, "inclination angle of the vertical gratings 51" refers to the angle at which the air guiding surface 510 of the vertical gratings 51 is inclined relative to the left-right dividing plane S. This further increases the airflow range in the left-right direction.

[0077] For example, two parallel groups 53 are provided on the left side of the left-right dividing plane S. In the parallel group 53 closer to the left-right dividing plane S, the air guide surface 510 of the vertical grille 51 is inclined at an angle β2 relative to the left-right dividing plane S. In the parallel group 53 closer to the left edge 111a of the air outlet, the air guide surface 510 of the vertical grille 51 is inclined at an angle β1 relative to the left-right dividing plane S, where β1 > β2. Similarly, two parallel groups 53 can also be provided on the right side of the left-right dividing plane S. These two parallel groups 53 can be arranged symmetrically with respect to the left-right dividing plane S, thus simplifying design and manufacturing.

[0078] In some embodiments, combined with Figure 4 One of the parallel groups 53 is the central group 531. The air guide surface 510 of each vertical grating 51 in the central group 531 extends from back to front parallel to the left-right dividing plane S. The central area of ​​the air outlet 111 in the central group 531, located in the left-right direction, has at least one vertical grating 51 arranged on each of the left and right sides of the left-right dividing plane S. This ensures that at least one vertical grating 51 extending from back to front parallel to the left-right dividing plane S is arranged on each of the left and right sides of the left-right dividing plane S. Thus, the vertical grating 51 directly in front can direct airflow forward, ensuring that the airflow directly in front is not weakened.

[0079] For example, the parallel groups 53 can be five groups, namely a central group 531, two parallel groups 53 located to the left of the central group 531, and two parallel groups 53 located to the right of the central group 531, so as to provide five air outlet angles. The airflow guided by the first air guide plate 41 can also be rectified again by the air outlet grille 5, thereby achieving a larger air supply range.

[0080] In some embodiments, combined with Figure 4 The air guide surface 510 of the leftmost vertical grid bar 51 extends to the left from back to front relative to the left and right dividing plane S, and forms a left air outlet gap G1 with the left edge 111a of the air outlet and the left air duct wall 31. The air guide surface 510 of the rightmost vertical grid bar 51 extends to the right from back to front relative to the left and right dividing plane S, and forms a right air outlet gap G2 with the right edge 111b of the air outlet and the right air duct wall 32.

[0081] It is understandable that an air duct is formed between the left air duct wall 31 and the right air duct wall 32. The left side wall of the left air outlet gap G1 is the left air duct wall 31 and the left edge 111a of the air outlet. The right side wall of the left air outlet gap G1 is the leftmost vertical grid bar 51. The left air outlet gap G1 is connected to the air duct. The left side wall of the right air outlet gap G2 is the rightmost vertical grid bar 51. The right side wall of the right air outlet gap G2 is the right air duct wall 32 and the right edge 111b of the air outlet. The right air outlet gap G2 is connected to the air duct. In this way, the airflow flowing out along the air duct can not only pass through the air outlet grille 5, but also flow out through the left air outlet gap G1 and the right air outlet gap G2, thereby increasing the air outlet range and air volume on both sides, which is conducive to achieving a full-area airflow effect.

[0082] In some embodiments, combined with Figure 3 and Figure 4 The leftmost vertical bar 51 and the rightmost vertical bar 51 are both edge vertical bars 511. The lateral spacing between the edge vertical bar 511 and the corresponding side edge of the air outlet 111 is greater than the lateral spacing between any two adjacent vertical bars 51. The length of the edge vertical bar 511 extending from back to front is greater than the length of any other vertical bar 51 extending from back to front. The edge vertical bar 511 includes a straight section 5111 and a bent section 5112 arranged sequentially from back to front. The bent section 5112 is obtusely deflected relative to the straight section 5111 towards the corresponding side edge of the air outlet 111. That is, the bent section 5112 is deflected relative to the straight section 5111 towards the corresponding side edge near the air outlet 111, and the angle β3 between the bent section 5112 and the straight section 5111 is an obtuse angle. For example, β3 can be greater than 90° and less than 120°, such as 90°, 95°, 100°, 105°, 110°, 115°, 120°, etc.

[0083] That is, the straight section 5111 of the left edge vertical grille 511 extends from back to front parallel to the left-right dividing plane S, and the bent section 5112 of the left edge vertical grille 511 bends from the front end of the straight section 5111 toward the left edge 111a near the air outlet 111, with the angle between the bent section 5112 and the straight section 5111 being an obtuse angle less than 120°. The straight section 5111 of the right edge vertical grille 511 extends from back to front parallel to the left-right dividing plane S, and the bent section 5112 of the right edge vertical grille 511 bends from the front end of the straight section 5111 toward the right edge 111b near the air outlet 111, with the angle between the bent section 5112 and the straight section 5111 being an obtuse angle less than 120°.

[0084] Therefore, the edge vertical grid strips 511 have good structural strength, and the straight section 5111 can play a certain role in blocking, while the bent section 5112 can play a role in guiding the flow.

[0085] In some embodiments, combined with Figure 2 , Figure 4 and Figure 6 The length direction of the air outlet grille 5 is vertical, and the width direction of the air outlet grille 5 is horizontal. The width U of the air outlet grille 5 from the leftmost vertical bar 51 to the rightmost vertical bar 51 is greater than or equal to 90% of the width L of the air outlet 111 in the horizontal direction. The air outlet grille 5 also includes a plurality of horizontal bars 52 extending in the horizontal direction and spaced vertically. The horizontal spacing T1 between adjacent vertical bars 51 is less than 1 / 3 of the vertical spacing T2 between adjacent horizontal bars 52. The vertical bars 51 protrude from the front side of the horizontal bars 52.

[0086] Among them, "the width U of the air outlet grille 5 from the leftmost vertical bar 51 to the rightmost vertical bar 51 is greater than or equal to 90% of the width L of the air outlet 111 in the left-right direction". For example, the width U of the air outlet grille 5 from the leftmost vertical bar 51 to the rightmost vertical bar 51 can be 0.9 times, 0.91 times, 0.92 times, 0.93 times, 0.94 times, 0.95 times, etc. of the width L of the air outlet 111 in the left-right direction.

[0087] Among them, "the horizontal spacing T1 of adjacent vertical bars 51 is less than 1 / 3 of the vertical spacing T2 of adjacent horizontal bars 52". For example, the horizontal spacing T1 of adjacent vertical bars 51 can be 0.3 times, 0.25 times, 0.2 times, 0.15 times, 0.1 times, 0.05 times, etc. of the vertical spacing T2 of adjacent horizontal bars 52.

[0088] Therefore, the vertical grille bars 51 are spaced closer together and protrude from the front of the horizontal grille bars 52, making the horizontal grille bars 31 hidden behind the vertical grille bars 32. This makes it difficult for users to observe the horizontal grille bars 31, improving the visual effect and overall appearance. It also facilitates surface treatments on the front surface of the vertical grille bars 51, such as gold plating. In addition, the small spacing and dense arrangement of the vertical grille bars 51 can effectively prevent larger foreign objects from entering the air conditioner, providing protection and protecting the heat exchanger, fan, and other components inside the air conditioner from damage, thus extending the service life of the air conditioner 100.

[0089] In some embodiments, combined with Figure 2 and Figure 7 The air conditioner 100 includes a panel component 1, which includes a panel body 11, a display panel 12, and a shielding panel 13. An air outlet 111 is formed on the panel body 11. An air outlet grille 5 is detachably connected to the panel body 11. The display panel 12 is installed on the panel body 11 and located above the air outlet grille 5. The shielding panel 13 is detachably installed on the panel body 11 and located below the air outlet grille 5, and shields the connection unlocking part between the air outlet grille 5 and the panel body 11. That is, after removing the shielding panel 13, an unlocking operation can be performed to release the connection lock between the air outlet grille 5 and the panel body 11, thereby enabling the removal of the air outlet grille 5.

[0090] The display panel 12 forms an upper left gap G3 and an upper right gap G4 between its left and right sides and the panel body 11, respectively. The shielding panel 13 forms a lower left gap G5 and a lower right gap G6 between its left and right sides and the panel body 11, respectively. The upper left gap G3 and the lower left gap G5 are connected to the upper and lower sides of the left air outlet gap G1, respectively, and the three gaps have the same width. The upper right gap G4 and the lower right gap G6 are connected to the upper and lower sides of the right air outlet gap G2, respectively, and the three gaps have the same width.

[0091] Therefore, the upper left gap G3, the left side air outlet gap G1, and the lower left gap G5 are arranged sequentially from top to bottom and connected, forming a continuous gap on the left side; similarly, the upper right gap G4, the right side air outlet gap G2, and the lower right gap G6 are arranged sequentially from top to bottom and connected, forming a continuous gap on the right side, thus improving the overall visual effect. For example, the upper left gap G3 and the upper right gap G4 are arranged in a recessed shape, which facilitates the installation of light-emitting components to achieve a light-emitting effect. For example, the lower left gap G5 and the lower right gap G6 are arranged in a recessed shape, which facilitates the holding and disassembly of the shielding panel 13.

[0092] For example, combined Figure 1 and Figure 7The air conditioner 100 may also include a display module 8, a rear housing 71, a top cover 72, and a base 73. The display module 8 is located on the rear side of the display panel 12, the panel component 1 is installed on the front side of the rear housing 71, the top cover 72 is located on the top of the rear housing 71, and both the panel component 1 and the rear housing 71 are located on the top of the base 73.

[0093] In some embodiments, combined with Figure 3 and Figure 8 One of the left air duct wall 31 and the right air duct wall 32 is designated as the first air duct wall 3a, and the other as the second air duct wall 3b. That is, when the first air duct wall 3a serves as the left air duct wall 31, the second air duct wall 3b serves as the right air duct wall 32; or, when the first air duct wall 3a serves as the right air duct wall 32, the second air duct wall 3b serves as the left air duct wall 31. For simplicity, the following description will use the example of the first air duct wall 3a serving as the left air duct wall 31 and the second air duct wall 3b serving as the right air duct wall 32.

[0094] Combination Figure 8 The first air duct wall 3a includes a first wall portion 3a1 and a second wall portion 3a2 that are smoothly connected along the air outlet direction. The second air duct wall 3b includes a third wall portion 3b1 and a fourth wall portion 3b2 that are smoothly connected along the air outlet direction. The third wall portion 3b1 extends in a straight line from the rear to the front. The front and rear ends of the first wall portion 3a1 and the third wall portion 3b1 are flush with each other. That is, the rear end of the first wall portion 3a1 is flush with the rear end of the third wall portion 3b1 (i.e., the distance from the center of the cross-flow impeller 2 in the front-rear direction is equal to that of the third wall portion 3b1), and the front end of the first wall portion 3a1 is flush with the front end of the third wall portion 3b1 (i.e., the distance from the center of the cross-flow impeller 2 in the front-rear direction is equal to that of the third wall portion 3b1).

[0095] Combination Figure 8 A first diffusion section 3d is formed between the first wall portion 3a1 and the third wall portion 3b1. The extension line M1 of the second wall portion 3a2 extends away from the second air duct wall 3b relative to the first wall portion 3a1. The extension line M2 of the fourth wall portion 3b2 extends away from the first air duct wall 3a relative to the third wall portion 3b1. A second diffusion section 3e is formed between the second wall portion 3a2 and the fourth wall portion 3b2. The first air guide plate 41 is disposed in the second diffusion section 3e.

[0096] For example, the first air duct wall 3a includes a volute tongue structure 3c, the second air duct wall 3b includes a volute shell structure 3g, the rear end of the third wall portion 3b1 is smoothly connected to the volute shell structure 3g, the rear end of the first wall portion 3a1 is smoothly connected to the volute tongue structure 3c, the front end of the third wall portion 3b1 and the front end of the fourth wall portion 3b2 extend to the left and right edges of the air outlet 111 respectively, and the airflow can flow into the first diffuser section 3d along the volute shell structure 3g after flowing out from the cross-flow impeller 2, and then flow into the second diffuser section 3e along the first diffuser section 3d, and then flow out from the air outlet 111.

[0097] The first wall portion 3a1 and the third wall portion 3b1 extend in roughly the same direction (e.g., both extend from back to front to the left front) and there is a certain difference in the extension angle (i.e. there is a small angle between the two extension directions), which is the expansion angle formed between the first wall portion 3a1 and the third wall portion 3b1; the second wall portion 3a2 and the fourth wall portion 3b2 extend in roughly opposite directions (e.g., one extends from back to front to the left front, and the other extends from back to front to the right front).

[0098] Therefore, the air duct adopts a secondary diffusion form, undergoing a sudden expansion in the second diffusion section 3e. Compared with a single diffusion channel, this increases the pressure at the outlet 111, which helps reduce noise. Furthermore, the smooth connection between the first wall portion 3a1 and the second wall portion 3a2 (connected by a smooth curve), and the smooth connection between the third wall portion 3b1 and the fourth wall portion 3b2 (connected by a smooth curve), reduces vortices and noise when the airflow enters the second diffusion section 3e from the first diffusion section 3d, improving aerodynamic performance and reducing noise. This facilitates the connection of a larger outlet 111, improving overall airflow performance in the left and right directions. When combined with the aforementioned rotatable first air guide plate 41 and the multi-angle air outlet grille 5, it further enhances overall airflow performance and improves comfort. With a single diffusion channel, increasing the airflow volume requires increasing the duct length, thus increasing the overall length. However, with a dual diffusion channel, this can be achieved without increasing the duct length.

[0099] In some embodiments, reference Figure 8 The third wall portion 3b1 extends from back to front with a length of L4, and the first diffuser section 3d has a dimension of h1 in the front-rear direction, wherein L4 > D / 2 (e.g., L4 can be 0.55D, 0.6D, 0.7D, 0.8D, D, 1.2D, 1.5D, etc.) and / or h1 > D / 3 (e.g., h1 can be 0.35D, 0.4D, 0.45D, 0.5D, 0.6D, 0.7D, 0.8D, D, 1.2D). The diffusion angle formed between the first wall portion 3a1 and the third wall portion 3b1 is 10°-20° (for example, the diffusion angle can be 10°, 12°, 14°, 16°, 18°, 20°, etc.), and the dimension of the second diffusion section 3e in the front-rear direction is h2, 0.8≤h2 / h1≤1.5 (for example, h2 / h1 can be 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, etc.). Therefore, the airflow velocity flowing into the first diffusion section 3d along the volute structure 3g is relatively stable, reducing noise.

[0100] In some embodiments, reference Figure 8The shortest distance from the volute tongue structure 3c to the second duct wall 3b is L1. The left-right dimension of the front end of the first diffuser section 3d is L2, and the left-right dimension of the front end of the second diffuser section 3e is L3. 0.6 ≤ L1 / D ≤ 0.8 (e.g., L1 / D can be 0.6, 0.65, 0.7, 0.75, 0.8, etc.); 1.5 ≤ L2 / D ≤ 2 (e.g., L2 / D can be 1.5, 1.6, 1.7, 1.8, 1.9, 2, etc.); 2.2 ≤ L3 / D ≤ 2.5 (e.g., L3 / D can be 2.2, 2.3, 2.4, 2.5, etc.). Therefore, the secondary diffusion effect can be optimized, facilitating large-area, comprehensive air supply and reducing noise.

[0101] In some embodiments, reference Figure 8 The second wall portion 3a2 includes a first curved segment 3a21. The length of the first curved segment 3a21 extending from back to front is greater than half the length of the second wall portion 3a2 extending from back to front. The first curved segment 3a21 is formed as a curve that bulges away from the second air duct wall 3b relative to the line M3 connecting the front and rear ends of the second wall portion 3a2, thereby creating a clearance space 3f between the extension line M1 of the second wall portion 3a2 and the first wall portion 3a1. This facilitates increasing the sudden expansion effect of the second diffusion section, which is beneficial for pressurization and noise reduction.

[0102] In some embodiments, reference Figure 8 The first air guide plate 41, located near the first air duct wall 3a, is positioned so that it can extend into the open space 3f. This improves the airflow regulation effect at the sudden expansion location.

[0103] In some embodiments, reference Figure 8 The fourth wall portion 3b2 bends away from the first air duct wall 3a relative to the third wall portion 3b1, and the angle γ between the line M4 connecting the front and rear ends of the fourth wall portion 3b2 and the third wall portion 3b1 is obtuse. The fourth wall portion 3b2 includes a second curved segment 3b21 extending forward from the rear end of the fourth wall portion 3b2. The extension length of the second curved segment 3b21 from back to front is greater than 1 / 2 of the extension length of the fourth wall portion 3b2 from back to front. The second curved segment 3b21 is formed as a curve that bulges towards the first air duct wall 3a relative to the line M4 connecting the front and rear ends of the fourth wall portion 3b2. This facilitates the smooth flow of air through the first diffuser section 3d into the second diffuser section 3e, reducing eddies, noise, and other problems, and improving aerodynamic performance.

[0104] In some embodiments, reference Figure 8 The second wall portion 3a2 extends from back to front in a double-wavy shape and transitions tangentially to the first wall portion 3a1. This facilitates a smooth flow of air through the first diffuser section 3d into the second diffuser section 3e, reducing eddies, noise, and other problems, and improving aerodynamic performance.

[0105] In some embodiments, reference Figure 8 The fourth wall portion 3b2 extends from back to front in a single-wave shape and transitions tangentially to the third wall portion 3b1. This facilitates a smooth flow of air through the first diffuser section 3d into the second diffuser section 3e, reducing eddies, noise, and other problems, and improving aerodynamic performance.

[0106] In some embodiments, reference Figures 8-10 The air conditioner 100 also includes a second air guide plate component 6, which includes a second air guide plate 61, at least most of which is located in the first diffuser section 3d. The second air guide plate 61 is rotatable about a horizontal axis extending in the horizontal direction. That is, all or most of the second air guide plate 61 is located within the first diffuser section 3d. Since the second air guide plate 61 is rotatable about a horizontal axis extending in the horizontal direction, it can rotate up and down to adjust the up and down air supply angle, and thus improve the air supply range of the whole unit in the vertical direction.

[0107] The composition of the second air guide plate component 6 is not limited. For example, it may include a plurality of second air guide plates 61 arranged at intervals in the vertical direction. The plurality of second air guide plates 61 can be connected by a second connecting rod 62 extending vertically, so that the second connecting rod 62 can be pulled up and down by a drive motor, thereby driving the plurality of second air guide plates 61 to rotate up and down synchronously.

[0108] In some embodiments, reference Figure 9 The air conditioner 100 also includes a protective net 9, which is located in the second diffuser section 3e and upstream of the first air guide plate 41 and downstream of the second air guide plate 61. This improves safety and meets safety regulations without affecting airflow.

[0109] In some embodiments, reference Figure 11 and Figure 12 The first air guide plate 41 is multiple and arranged in the left-right direction. The first air guide plate component 4 includes multiple linkage units 40 arranged in the left-right direction. Each linkage unit 40 includes multiple first air guide plates 41 arranged adjacent to each other. Each linkage unit 40 also includes a first connecting rod 42 connected to all the first air guide plates 41 in the same linkage unit 40. The first connecting rod 42 pulls each first air guide plate 41 in the linkage unit 40 to rotate synchronously. The multiple linkage units 40 are driven by separate motors.

[0110] In the above technical solution, multiple first air guide plates 41 in the same linkage unit 40 are connected by a first link 42, so that all the first air guide plates 41 in the entire linkage unit 40 move synchronously. Thus, only one drive motor is needed to realize the linkage adjustment of multiple first air guide plates 41, and the consistency of multiple first air guide plates 41 when adjusting the angle can be guaranteed. This makes the airflow guidance in the same linkage unit 40 more coordinated. Compared with equipping each first air guide plate 41 with a separate drive motor, the control and production costs are reduced.

[0111] Furthermore, employing multiple linkage units 40 reduces the number of drive motors required and enables independent control of different linkage units 40, thereby allowing for the combination of more air delivery effects and achieving a larger air delivery range. There can be two or three linkage units 40, and the number of first air guide plates 41 included in each linkage unit 40 can be two, three, four, or five, etc.

[0112] In some embodiments, reference Figure 11 and Figure 12 One of the left air duct wall 31 and the right air duct wall 32 is the first air duct wall 3a, and the other is the second air duct wall 3b. The inlet end of the first air duct wall 3a is formed as a volute tongue structure 3c. The linkage unit 40 consists of two units, the first linkage unit 40a and the second linkage unit 40b, which are arranged in the direction from the first air duct wall 3a to the second air duct wall 3b. All the first air guide plates 41 are evenly distributed. The number of first air guide plates 41 included in the first linkage unit 40a is less than the number of first air guide plates 41 included in the second linkage unit 40b.

[0113] In the above technical solution, when the airflow is sent out between the left air duct wall 31 and the right air duct wall 32, it is easier to flow towards the first linkage unit 40a. By setting the number of first air guide plates 41 included in the first linkage unit 40a to be less than the number of first air guide plates 41 included in the second linkage unit 40b, the amount of airflow out of the second linkage unit 40b is increased, thereby making the airflow through the first linkage unit 40a and the second linkage unit 40b relatively balanced, improving the uniformity of airflow on the left and right sides, and improving the user experience.

[0114] For example, the first linkage unit 40a includes two first air guide plates 41, and the second linkage unit 40b includes three first air guide plates 41. Both the first linkage unit 40a and the second linkage unit 40b are individually controlled by a drive motor to turn left and right. In this embodiment, when the first air guide plate 41 in the first linkage unit 40a turns to the left at its maximum angle, and the first air guide plate 41 in the second linkage unit 40b turns to the right at its maximum angle, the airflow can be directed out over a wider range and more evenly, which is beneficial for achieving full-area airflow.

[0115] The following describes an air conditioner 100 according to a specific embodiment of the present invention.

[0116] The air duct structure 3 defines the air duct, which includes a left air duct wall 31 and a right air duct wall 32 extending from the air duct inlet to the air duct outlet. The cross-flow impeller 2 is located at the air duct inlet, and the air duct outlet extends to the air outlet 111. The left air duct wall 31 and the right air duct wall 32 are composed of multiple arc segments and straight segments, respectively, with the arcs and straight lines being tangent. The air duct is divided into an annular air duct and a circumferential air duct. The annular air duct is defined by a volute tongue structure 3c and a volute shell structure 3g. The annular air duct is set in an arc shape, and the cross-flow impeller 2 is located inside the annular air duct. The air drawn in by the cross-flow impeller 2 can enter the circumferential air duct more smoothly. The circumferential air duct consists of a first diffuser section 3d and a second diffuser section 3e.

[0117] The first diffusion section 3d is defined by the first wall portion 3a1 of the left duct wall 31 and the third wall portion 3b1 of the right duct wall 32. The diffusion angle formed between the first wall portion 3a1 and the third wall portion 3b1 is controlled within the range of 10°-20°, which can make the airflow velocity entering the circumferential duct of the circumferential duct most stable and reduce noise.

[0118] The second diffuser section 3e is defined by the second wall portion 3a2 of the left duct wall 31 and the fourth wall portion 3b2 of the right duct wall 32. The second wall portion 3a2 has a double-wavy shape, and its arc segment transitions tangentially to the first wall portion 3a1. The fourth wall portion 3b2 has a single-wavy shape and also transitions tangentially to the third wall portion 3b1. Air exiting the first diffuser section 3d enters the passage of the second diffuser section 3e along the arc segment. The end of the second diffuser section 3e extends to the air outlet 111.

[0119] The same airflow entering the aforementioned circumferential duct, passing through two diffuser channels, increases the pressure at the outlet 111 compared to a single diffuser channel. With a single diffuser channel, increasing the airflow requires increasing the duct length, thus increasing the overall length. The dual diffuser channel technology achieves this without requiring additional duct length. In summary, this design, with a larger outlet 111 and a dual diffuser duct, increases the airflow area in the left and right directions, improves aerodynamic performance, and reduces noise. Combined with multiple first air guide plates 41 and multi-angle airflow grilles, it facilitates comprehensive airflow, resulting in a large airflow area and angle, thus enhancing comfort.
