[0043] 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0044] The following is for reference. Figures 1-12 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0045] like Figures 1-3As shown, the air conditioner 100 according to an embodiment of the present utility model includes an air conditioner body 10, the air conditioner body 10 has an air duct 120 and an air outlet 101, and the outlet of the air duct 120 is connected to the air outlet 101.

[0046] like Figure 4 As shown, the air conditioner 100 also includes an air outlet grille 20, which is located at the air outlet 101. The air outlet grille 20 has multiple air outlet zones arranged in its width direction, and the air outlet zones have different air outlet directions. Here, the air outlet grille 20 serves both as an external component of the air conditioner 100 and as a guide for airflow, allowing the air conditioner 100 to outlet air from multiple directions during operation.

[0047] The air outlet grille 20 includes multiple vertical ribs 21 arranged in its width direction. Each vertical rib 21 extends along the length direction of the air outlet grille 20, and there is an air outlet gap between adjacent vertical ribs 21. The width direction of the multiple vertical ribs 21 in the same air outlet area is consistent, while the width direction of the vertical ribs 21 in different air outlet areas is different.

[0048] It should be noted that the longest extension direction of the vertical rib 21 is defined as its length direction, and the width direction of the vertical rib 21 is perpendicular to its length direction. In a cross-section perpendicular to the length direction of the vertical rib 21, the extension direction of the longer side of the cross-section is defined as its width direction, and the extension direction of the shorter side of the cross-section is defined as its thickness direction. Specifically... Figure 4 In this context, for each vertical rib 21, the width direction of the vertical rib 21 is the extension direction between the front and rear sides of the vertical rib 21, and the thickness direction of the vertical rib 21 is the extension direction between the left and right sides of the vertical rib 21.

[0049] In the embodiments of this application, the width directions of multiple vertical ribs 21 in the same air outlet area are consistent. For example, the width directions of multiple vertical ribs 21 in the same air outlet area are all set at the same preset angle relative to the front-back direction. However, the width directions of the vertical ribs 21 in different air outlet areas are different. For example, the angle between the width directions of multiple vertical ribs 21 in one air outlet area and the front-back direction is α, while the angle between the width directions of multiple vertical ribs 21 in another air outlet area and the front-back direction is β. α and β are not equal.

[0050] According to the embodiment of the present utility model, the air conditioner 100 sets the multiple air outlet zones of the air outlet grille 20 to have different air outlet directions, sets the width direction of the multiple vertical ribs 21 in the same air outlet zone to be the same, and sets the width direction of the vertical ribs 21 in different air outlet zones to be different. This can make the airflow coverage at the air outlet 101 wider and more evenly distributed in the indoor space, avoid the situation of local temperature being too low or too high, and help improve the comfort of the indoor space.

[0051] In this embodiment, the air outlet grille 20 is made of materials with high heat resistance, such as ABS plastic (Acrylonitrile Butadiene Styrene copolymer) and PC plastic (Polycarbonate).

[0052] In the embodiments of this application, such as Figure 5 As shown, the air conditioner 100 includes a housing 11, an air duct component 12, a heat exchanger 13, and a fan wheel 14. The housing 11 has an air inlet 102 and an air outlet 101. The air duct component 12 is disposed inside the housing 11 and defines an air outlet 120. The outlet of the air duct 120 is connected to the air outlet 101. The fan wheel 14 is disposed at the inlet of the air duct 120. The heat exchanger 13 is disposed inside the housing 11 and is located between the air inlet 102 and the fan wheel 14.

[0053] When the air conditioner 100 is running, the fan wheel 14 rotates, and the air outside the air conditioner 100 can enter the casing 11 through the air inlet 102, flow through the heat exchanger 13, enter the air duct 120, and finally be discharged to the outside of the air conditioner 100 through the air outlet 101.

[0054] The housing 11 includes a front housing 111 and a rear housing 112. The front housing 111 is connected to the front side of the rear housing 112. An air inlet 102 is located on the rear housing 112, and an air outlet 101 is located on the front housing 111. The front housing 111 includes an air outlet frame 1111 and a front panel 1112. The front panel 1112 serves as an exterior component, covering the outside of the air outlet frame 1111.

[0055] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the plurality of air outlet zones include at least a first air outlet zone 201 and a second air outlet zone 202. The air outlet direction of the first air outlet zone 201 is a first direction F1, and the air outlet direction of the second air outlet zone 202 is a second direction F2. The first direction F1 and the second direction F2 are set at a first preset angle.

[0056] like Figure 4 As shown, in some embodiments, the vertical rib 21 includes a first vertical rib 211, and the first air outlet zone 201 has a plurality of first vertical ribs 211, the width direction of each first vertical rib 211 extending along a first direction F1.

[0057] In other words, multiple first vertical ribs 211 are arranged in the width direction of the air outlet grille 20. The length direction of each first vertical rib 211 extends along the length direction of the air outlet grille 20, and the width direction of each first vertical rib 211 extends along the first direction F1. A first air outlet gap is defined between two adjacent first vertical ribs 211. When the airflow passes through the first air outlet gap, it can flow along the first direction F1 under the guidance of the first vertical ribs 211, thereby forming an air outlet effect of flowing along the first direction F1 in the first air outlet area 201.

[0058] like Figure 4 As shown, in some embodiments, the vertical rib 21 includes a second vertical rib 212, and the second air outlet zone 202 has a plurality of second vertical ribs 212, the width direction of each second vertical rib 212 extending along the second direction F2.

[0059] In other words, multiple second vertical ribs 212 are arranged in the width direction of the air outlet grille 20. The length direction of each second vertical rib 212 extends along the length direction of the air outlet grille 20, and the width direction of each second vertical rib 212 extends along the second direction F2. A second air outlet gap is defined between two adjacent second vertical ribs 212. When the airflow passes through the second air outlet gap, it can flow along the second direction F2 under the guidance of the second vertical ribs 212, thereby forming an air outlet effect of flowing along the second direction F2 in the second air outlet area 202.

[0060] The width direction of the first vertical rib 211 is set at a first preset angle with the width direction of the second vertical rib 212.

[0061] In the above technical solution, by setting the air outlet grille 20 to include multiple first vertical ribs 211 and multiple second vertical ribs 212, the multiple first vertical ribs 211 and multiple second vertical ribs 212 can guide the airflow, thereby forming an air outlet effect that flows in different directions in the first air outlet area 201 and the second air outlet area 202.

[0062] like Figure 4 As shown, in some embodiments, the first preset angle α1 is 15°-25°. For example, the first preset angle α1 can be 15°, 20°, 25°, etc. This setting allows the airflow from the second air outlet zone 202 to gradually move away from the airflow from the first air outlet zone 201, thereby increasing the airflow diffusion range, ensuring air supply comfort, and also maintaining the appearance refinement of the air outlet grille 20, enhancing the visual appeal.

[0063] like Figure 3 and Figure 4As shown, in some embodiments, the multiple air outlet zones also include a third air outlet zone 203. The first air outlet zone 201 is located between the second air outlet zone 202 and the third air outlet zone 203. The air outlet direction of the third air outlet zone 203 is the third direction F3, and the third direction F3 and the first direction F1 are set at a second preset angle.

[0064] like Figure 4 As shown, in some specific embodiments, the vertical rib 21 includes a third vertical rib 213, and the third air outlet zone 203 has a plurality of third vertical ribs 213, the width direction of each third vertical rib 213 extending along the third direction F3.

[0065] In other words, multiple third vertical ribs 213 are arranged in the width direction of the air outlet grille 20. The length direction of each third vertical rib 213 extends along the length direction of the air outlet grille 20, and the width direction of each third vertical rib 213 extends along the third direction F3. A third air outlet gap is defined between two adjacent third vertical ribs 213. When the airflow passes through the third air outlet gap, it can flow along the third direction F3 under the guidance of the third vertical ribs 213, thereby forming an air outlet effect of flowing along the third direction F3 in the third air outlet area 203.

[0066] The width direction of the first vertical rib 211 is set at a second preset angle with the width direction of the third vertical rib 213.

[0067] In the above technical solution, by setting the air outlet grille 20 to include multiple first vertical ribs 211, multiple second vertical ribs 212 and multiple third vertical ribs 213, the multiple first vertical ribs 211, multiple second vertical ribs 212 and multiple third vertical ribs 213 can guide the airflow, thereby forming an air outlet effect that flows in different directions in the first air outlet area 201, the second air outlet area 202 and the third air outlet area 203.

[0068] like Figure 4 As shown, in some embodiments, the second preset angle α2 is 15°-25°. For example, the second preset angle α2 can be 15°, 20°, 25°, etc. This setting allows the airflow from the third air outlet zone 203 to gradually move away from the airflow from the first air outlet zone 201, thereby increasing the airflow diffusion range, ensuring air supply comfort, and also maintaining the appearance refinement of the air outlet grille 20, enhancing the visual appeal.

[0069] In some specific embodiments, the width direction of the air outlet grille 20 is the left-right direction, and the length direction of the air outlet grille 20 is the up-down direction. The first direction F1, the width direction of the air outlet grille 20, and the length direction of the air outlet grille 20 are arranged perpendicularly to each other. That is to say, the first direction F1 is the front-back direction.

[0070] In the plane perpendicular to the vertical direction, the projections of multiple second vertical ribs 212 and multiple third vertical ribs 213 are symmetrically arranged about the center line of the air outlet grille 20 extending along the first direction F1, that is, the multiple second vertical ribs 212 and multiple third vertical ribs 213 are arranged symmetrically to the left and right in a one-to-one correspondence.

[0071] This configuration allows the air outlets of the second air outlet zone 202 and the third air outlet zone 203 to be symmetrically positioned, thereby improving the air supply comfort of the air conditioner 100 and ensuring the exquisite appearance of the air outlet grille 20, enhancing the visual appeal.

[0072] like Figure 3 and Figure 4 As shown, in some specific embodiments, the multiple air outlet zones also include a fourth air outlet zone 204. The fourth air outlet zone 204 is located on the side of the second air outlet zone 202 away from the first air outlet zone 201. The air outlet direction of the fourth air outlet zone 204 is the fourth direction F4, and the fourth direction F4 and the first direction F1 are set at a third preset angle.

[0073] like Figure 4 As shown, in some examples, the vertical rib 21 includes a fourth vertical rib 214, and the fourth air outlet zone 204 has a plurality of fourth vertical ribs 214, each of which extends in the width direction along the fourth direction F4.

[0074] In other words, multiple fourth vertical ribs 214 are arranged in the width direction of the air outlet grille 20. The length direction of each fourth vertical rib 214 extends along the length direction of the air outlet grille 20, and the width direction of each fourth vertical rib 214 extends along the fourth direction F4. A fourth air outlet gap is defined between two adjacent fourth vertical ribs 214. When the airflow passes through the fourth air outlet gap, it can flow along the fourth direction F4 under the guidance of the fourth vertical ribs 214, thereby forming an air outlet effect of flowing along the fourth direction F4 in the fourth air outlet area 204.

[0075] The width direction of the first vertical rib 211 is set at a third preset angle with the width direction of the fourth vertical rib 214.

[0076] In the above technical solution, by setting the air outlet grille 20 to include multiple first vertical ribs 211, multiple second vertical ribs 212, multiple third vertical ribs 213 and multiple fourth vertical ribs 214, the multiple first vertical ribs 211, multiple second vertical ribs 212, multiple third vertical ribs 213 and multiple fourth vertical ribs 214 can guide the airflow, thereby forming an air outlet effect with airflow in different directions in the first air outlet area 201, the second air outlet area 202, the third air outlet area 203 and the fourth air outlet area 204.

[0077] like Figure 4As shown, in some examples, the third preset angle is 35°-45°. That is, the angle between the width direction of the fourth vertical rib 214 and the width direction of the first vertical rib 211 is greater than the angle between the width direction of the second vertical rib 212 and the width direction of the first vertical rib 211. For example, the third preset angle is 35°, 40°, 45°, etc.

[0078] This configuration allows the airflow from the fourth air outlet zone 204 to gradually move away from the airflow from the first air outlet zone 201 and the second air outlet zone 202, thereby increasing the airflow diffusion range, ensuring air supply comfort, and also maintaining the refined appearance of the air outlet grille 20, enhancing the visual appeal.

[0079] like Figure 3 and Figure 4 As shown, in some examples, the multiple air outlet zones also include a fifth air outlet zone 205, which is located on the side of the third air outlet zone 203 away from the first air outlet zone 201. The air outlet direction of the fifth air outlet zone 205 is the fifth direction F5, and the fifth direction F5 and the first direction F1 are set at a fourth preset angle.

[0080] like Figure 4 As shown, in some specific examples, the vertical rib 21 includes a fifth vertical rib 215, and the fifth air outlet zone 205 has a plurality of fifth vertical ribs 215, each fifth vertical rib 215 extending in the width direction along the fifth direction F5.

[0081] In other words, multiple fifth vertical ribs 215 are arranged in the width direction of the air outlet grille 20. The length direction of each fifth vertical rib 215 extends along the length direction of the air outlet grille 20, and the width direction of each fifth vertical rib 215 extends along the fifth direction F5. A fifth air outlet gap is defined between two adjacent fifth vertical ribs 215. When the airflow passes through the fifth air outlet gap, it can flow along the fifth direction F5 under the guidance of the fifth vertical ribs 215, thereby forming an air outlet effect of flowing along the fifth direction F5 in the fifth air outlet area 205.

[0082] The width direction of the first vertical rib 211 is set at a fourth preset angle with the width direction of the fifth vertical rib 215.

[0083] In the above technical solution, by setting the air outlet grille 20 to include multiple first vertical ribs 211, multiple second vertical ribs 212, multiple third vertical ribs 213, multiple fourth vertical ribs 214 and multiple fifth vertical ribs 215, the multiple first vertical ribs 211, multiple second vertical ribs 212, multiple third vertical ribs 213, multiple fourth vertical ribs 214 and multiple fifth vertical ribs 215 can guide the airflow, thereby forming an air outlet effect with airflow in different directions in the first air outlet area 201, the second air outlet area 202, the third air outlet area 203, the fourth air outlet area 204 and the fifth air outlet area 205.

[0084] like Figure 4 As shown, in some examples, the fourth preset angle is 35°-45°. That is, the angle between the width direction of the fifth vertical rib 215 and the width direction of the first vertical rib 211 is greater than the angle between the width direction of the third vertical rib 213 and the width direction of the first vertical rib 211. For example, the fourth preset angle is 35°, 40°, 45°, etc.

[0085] This configuration allows the airflow from the fifth air outlet zone 205 to gradually move away from the airflow from the first air outlet zone 201 and the third air outlet zone 203, thereby increasing the airflow diffusion range, ensuring air supply comfort, and also maintaining the appearance refinement of the air outlet grille 20, enhancing the visual appeal.

[0086] In some specific examples, the width direction of the air outlet grille 20 is the left-right direction, and the length direction of the air outlet grille 20 is the up-down direction. The first direction F1, the width direction of the air outlet grille 20, and the length direction of the air outlet grille 20 are set perpendicular to each other. That is to say, the first direction F1 is the front-back direction.

[0087] In the plane perpendicular to the vertical direction, the projections of multiple fourth vertical ribs 214 and multiple fifth vertical ribs 215 are symmetrically arranged about the center line of the air outlet grille 20 extending along the first direction F1, that is, the multiple fourth vertical ribs 214 and multiple fifth vertical ribs 215 are arranged symmetrically to the left and right in a one-to-one correspondence.

[0088] This configuration allows the air outlets of the fourth air outlet zone 204 and the fifth air outlet zone 205 to be symmetrically positioned, thereby improving the air supply comfort of the air conditioner 100 and ensuring the exquisite appearance of the air outlet grille 20, enhancing the visual appeal.

[0089] like Figure 3 As shown, in some embodiments, the air outlet grille 20 further includes a plurality of horizontal ribs 22, which are spaced apart along the length of the vertical ribs 21, and each horizontal rib 22 is connected to the plurality of vertical ribs 21.

[0090] Specifically, taking the side surface of the horizontal rib 22 facing away from the air duct 120 as the reference surface, the vertical rib 21 partially protrudes from the reference surface. That is to say, the side surface of the vertical rib 21 facing away from the air duct 120 is further away from the air duct 120 than the side surface of the horizontal rib 22 facing away from the air duct 120, thus forming a step at the connection between the side surface of the vertical rib 21 facing away from the air duct 120 and the side surface of the horizontal rib 22 facing away from the air duct 120.

[0091] In the above technical solution, by setting multiple horizontal ribs 22, multiple vertical ribs 21 can be connected together, thereby improving the structural strength of the air outlet grille 20 and preventing the air outlet grille 20 from deforming due to long-term use; by making the vertical ribs 21 at least partially protrude from the side surface of the horizontal ribs 22 away from the air duct 120, the air outlet grille 20 can be used as an appearance component, visually achieving the effect of hiding the horizontal ribs 22 and improving the appearance refinement of the air outlet grille 20.

[0092] like Figure 4 As shown, in some examples, the surfaces of multiple vertical ribs 21 facing away from the air duct 120 are on the same cylindrical surface. That is, multiple air outlet zones are arranged in the circumferential direction of the cylindrical surface.

[0093] For example, multiple air outlet zones include a first air outlet zone 201, a second air outlet zone 202, a third air outlet zone 203, a fourth air outlet zone 204, and a fifth air outlet zone 205. These zones are arranged circumferentially on the cylindrical surface. The air outlet direction of the first air outlet zone 201 is from back to front. The second air outlet zone 202 and the fourth air outlet zone 204 are located to the left of the first air outlet zone 201, and the second air outlet zone... The air outlet direction of 202 forms an angle of 20° with the air outlet direction of the first air outlet area 201. The air outlet direction of the fourth air outlet area 204 forms an angle of 40° with the air outlet direction of the first air outlet area 201. The third air outlet area 203 and the fifth air outlet area 205 are located to the right of the first air outlet area 201, and the air outlet direction of the third air outlet area 203 forms an angle of 20° with the air outlet direction of the first air outlet area 201, and the air outlet direction of the fifth air outlet area 205 forms an angle of 40° with the air outlet direction of the first air outlet area 201.

[0094] The first air outlet area 201 has a plurality of first vertical ribs 211, which are arranged circumferentially on the cylindrical surface at intervals, and the width direction of each first vertical rib 211 extends along a first direction F1. The second air outlet area 202 has a plurality of second vertical ribs 212, which are arranged circumferentially on the cylindrical surface at intervals, and the width direction of each second vertical rib 212 extends along a second direction F2. The third air outlet area 203 has a plurality of third vertical ribs 213, which are arranged circumferentially on the cylindrical surface at intervals, and the width direction of each third vertical rib 213 extends along a third direction F3. The fourth air outlet area 204 has a plurality of fourth vertical ribs 214, which are arranged circumferentially on the cylindrical surface at intervals, and the width direction of each fourth vertical rib 214 extends along a fourth direction F4. The fifth air outlet zone 205 has multiple fifth vertical ribs 215, which are arranged circumferentially on the cylindrical surface. The width direction of each fifth vertical rib 215 extends along the fifth direction F5.

[0095] In the above technical solution, by setting the surface of the multiple vertical ribs 21 facing away from the air duct 120 to be on the same cylindrical surface, on the one hand, the air blown out by the air conditioner 100 can be more evenly distributed in the room, reducing airflow dead angles, making the indoor temperature more balanced, and ensuring air supply comfort. On the other hand, the surface of the air outlet grille 20 can be more modern and smooth, enhancing the appearance of the air conditioner 100.

[0096] For example, the two corners of the vertical rib 21 on the side away from the air duct 120 have rounded corners. This design effectively avoids potential damage from sharp corners and facilitates cleaning. In addition, when airflow passes through the air outlet grille 20, the rounded corners make the airflow smoother, reducing airflow resistance and turbulence at the air outlet grille 20, and also enhancing the aesthetics of the air outlet grille 20.

[0097] For example, the vertical rib 21 has a apex angle on the side near the air duct 120. With this configuration, when the airflow passes through the air outlet grille 20, the apex angle can split the airflow, allowing the airflow to flow from the air outlet gaps on both sides of the vertical rib 21.

[0098] like Figure 3 As shown, in some examples, the distance L between two adjacent horizontal ribs 22 is 60mm-80mm. For example, the distance L between two adjacent horizontal ribs 22 can be 60mm, 65mm, 70mm, 75mm, 80mm, etc.

[0099] In the above technical solution, by limiting the distance between two adjacent horizontal ribs 22 to the above range, the structural strength of the air outlet grille 20 can be guaranteed, while avoiding the impact on the air volume and appearance of the air conditioner 100 due to too many horizontal ribs 22.

[0100] like Figure 3 As shown, in some examples, the distance M between two adjacent vertical ribs 21 is 5mm-7mm. For example, the distance M between two adjacent vertical ribs 21 can be 5mm, 6mm, 7mm, etc.

[0101] In the above technical solution, by limiting the distance between two adjacent vertical ribs 21 to the above range, while ensuring that the vertical ribs 21 have the minimum resistance to airflow, the horizontal ribs 22 can be visually hidden, thereby improving the appearance of the air conditioner 100 and improving the appearance quality of the air conditioner 100.

[0102] like Figure 2As shown, according to some embodiments of the present invention, the width A1 of the air outlet grille 20 is smaller than the width A2 of the air outlet 101. There is a flow gap 210 between the two sides of the air outlet grille 20 in the width direction and the two sides of the air outlet 101 in the width direction. The flow gap 210 connects the ventilation duct 120 and the external space of the air conditioner 100.

[0103] In other words, the airflow in the duct 120 can flow to the external space of the air conditioner 100 through the air outlet grille 20, or through the flow gap 210 between the air outlet grille 20 and the air outlet 101.

[0104] Compared with the air conditioner 100 in the related technology, this application increases the width of the air outlet 101 to be greater than the width of the air outlet grille 20, which can ensure the air volume of the air outlet 101 and thus ensure the air supply effect of the air conditioner 100.

[0105] like Figure 2 As shown, in some embodiments, the air conditioner 100 further includes an upper panel 30, which is mounted on the upper front side of the air conditioner body 10 and is located above the air outlet 101. The upper panel 30 has a first gap 301 between its two sides in the width direction and its upper end and the air conditioner body 10. The upper panel 30 can be a display panel or a control panel, etc.

[0106] The air conditioner 100 also includes a lower panel 40, which is installed on the lower front side of the air conditioner body 10 and is located below the air outlet 101. The lower panel 40 has a second gap 401 between its two sides in the width direction and its lower end and the air conditioner body 10.

[0107] The air vent grille 20 is located between the upper panel 30 and the lower panel 40. The two sides of the upper panel 30 in the width direction are flush with the two sides of the air vent grille 20 in the width direction, and the two sides of the lower panel 40 in the width direction are flush with the two sides of the air vent grille 20 in the width direction.

[0108] In other words, the air outlet grille 20 is located between the upper panel 30 and the lower panel 40. The two sides of the air outlet grille 20 in the width direction are respectively flush with the two sides of the upper panel 30 and the two sides of the lower panel 40 in the width direction. The flow gap 210 connects the first gap 301 and the second gap 401. This arrangement allows the upper panel 30, the air outlet grille 20 and the lower panel 40 to form a floating panel structure, making the front surface of the air conditioner 100 more modern and improving the aesthetic appearance of the air conditioner 100.

[0109] In some embodiments, the width of the first gap 301 is greater than the distance between two adjacent vertical ribs 21, and the width of the second gap 401 is greater than the distance between two adjacent vertical ribs 21.

[0110] According to some embodiments of this utility model, the length of the air outlet grille 20 is greater than the length of the air outlet 101 to prevent affecting the air outlet effect.

[0111] like Figure 6 and Figure 7 As shown, according to some embodiments of the present invention, the air conditioner 100 further includes a drive motor 23, which is connected to the air outlet grille 20 and is used to drive the air outlet grille 20 to swing within a preset angle range.

[0112] When the air conditioner 100 is running, the drive motor 23 can be controlled to drive the air outlet grille 20 to swing within a preset angle range to achieve air sweeping, thereby further increasing the diffusion range of the air outlet and ensuring air delivery comfort.

[0113] In some embodiments, the swing axis of the air outlet grille 20 is located at the middle of the air outlet grille 20 in its width direction, and the swing angle of the air outlet grille 20 is -20° to 20°.

[0114] Specifically, when the air outlet grille 20 is in its initial state, it is symmetrically arranged about the center line of the air conditioner 100 extending in the front-rear direction. When the air outlet grille 20 is in its initial state, it is defined that the air outlet grille 20 is located at the 0° position. The air outlet grille 20 can swing to the left by 20° under the drive of the drive motor 23, thereby swinging the air outlet grille 20 to the left to the first extreme position. The air outlet grille 20 can swing to the right by 20° under the drive of the drive motor 23, thereby swinging the air outlet grille 20 to the right to the second extreme position.

[0115] In the above technical solution, by limiting the swing range of the air outlet grille 20, the air supply effect of the air conditioner 100 can be controlled on the one hand, and the interference between the air outlet grille 20 and other components in the air duct 120 during the swing process can be avoided, which is conducive to ensuring the operational reliability of the air conditioner 100.

[0116] According to some embodiments of the present invention, in the airflow direction, the air duct 120 includes a first air duct section 1200 and a second air duct section 1201. The second air duct section 1201 connects the air outlet 101 and the first air duct section 1200, and the width of the second air duct section 1201 increases abruptly relative to the width of the first air duct section 1200. That is, the portion of the air duct 120 near the air outlet 101 has the second air duct section 1201 with a sudden increase in width.

[0117] The second air duct section 1201 is provided with multiple air guide plates 15, which are arranged in the width direction of the air outlet grille 20. Each air guide plate 15 can swing in the width direction of the air outlet grille 20.

[0118] In this configuration, some of the multiple air guide plates 15 are linked together, while others are linked together, so that some air guide plates 15 swing synchronously, and others swing synchronously. Alternatively, all of the multiple air guide plates 15 are linked together, so that all of the multiple air guide plates 15 swing synchronously.

[0119] Compared with the air conditioner 100 in the related technology, this application sets a part of the air duct 120 as a second air duct section 1201. On the one hand, it can ensure the air volume of the air outlet 101, thereby ensuring the air supply effect of the air conditioner 100. On the other hand, with the cooperation of the second air duct section 1201 and the air guide plate 15, it can achieve diffusion, so that the airflow coverage at the air outlet 101 is wider and can be more evenly distributed in the indoor space, avoiding the situation of local temperature being too low or too high, which helps to improve the comfort of the indoor space.

[0120] In some embodiments, the air duct 120 includes a first air duct section 1200 and a second air duct section 1201. The second air duct section 1201 connects the first air duct section 1200 and the air outlet 101. In the cross-section of the air conditioner 100, the first air duct section 1200 has two first air duct walls 120a arranged opposite to each other in the width direction of the air conditioner 100, and the second air duct section 1201 has two second air duct walls 1201a arranged opposite to each other in the width direction of the air conditioner 100. The connection between one of the first air duct walls 120a and the corresponding second air duct wall 1201a forms an inflection point of the air duct wall of the air duct 120, or the connection between the two first air duct walls 120a and the two corresponding second air duct walls 1201a both form inflection points of the air duct wall of the air duct 120.

[0121] Specifically, the second air duct wall 1201a is located on the side of the extension surface 120b of the first air duct wall 120a away from the center of the air duct 120. Here, the extension surface 120b of the first air duct wall 120a refers to an imaginary surface that extends and stretches along the original trend of the first air duct wall 120a. The second air duct wall 1201a can gradually move away from the corresponding extension surface 120b of the first air duct wall 120a from back to front, thereby causing the size of the second air duct section 1201 in the width direction of the air conditioner 100 to increase abruptly, and multiple air guide plates 15 are arranged in the width direction of the second air duct section 1201.

[0122] For example, with the cooperation of the second air duct section 1201 of the air duct 120 and the air guide plate 15, the airflow can be diffused through the second air duct section 1201 of the air duct 120, so that the airflow diffusion width at the air outlet 101 can be increased from 97mm to 237mm; under the action of the air outlet grille 20, the airflow can be diffused again through the air outlet grille 20, so that the airflow diffusion width at the air outlet 101 can be increased to 255mm, thereby making the airflow coverage at the air outlet 101 wider and more evenly distributed in the indoor space.

[0123] In some examples, the air duct 120 is also provided with multiple swing blades 16, which are linked together between the impeller 14 and the air guide plate 15, so that the multiple swing blades 16 can swing synchronously.

[0124] like Figures 8-12 As shown, according to some embodiments of the present invention, the lower end of the air outlet grille 20 in the length direction is provided with a first mating part 24, and the air conditioner body 10 is provided with a support part 173, which is located below the air outlet 101.

[0125] The air outlet grille 20 is provided with a locking member 241, which is movably disposed on the first mating part 24 in the vertical direction. The support part 173 is provided with a first insertion hole 171, which is positioned with its opening facing upward. The first mating part 24 can be supported on the support part 173, and the locking member 241 can be inserted into the first insertion hole 171 from top to bottom, so that the lower end of the air outlet grille 20 in the length direction is connected to the air conditioner body 10.

[0126] Alternatively, the air conditioner body 10 is provided with a locking member 241 that can move up and down. The first mating part 24 includes a first insertion hole 171 with the opening of the first insertion hole 171 facing downward. The air outlet grille 20 can be supported on the support part 173. The locking member 241 can be inserted into the first insertion hole 171 from bottom to top, so that the lower end of the air outlet grille 20 in the length direction is connected to the air conditioner body 10.

[0127] In some embodiments, the upper end of the air outlet grille 20 in the length direction is provided with a second mating part 25, the second mating part 25 being an upwardly extending pin, and the air conditioner body 10 is provided with a second insertion hole 172 with the opening facing downward. The pin can be inserted into the second insertion hole 172 from bottom to top, so that the upper end of the air outlet grille 20 in the length direction is connected to the air conditioner body 10.

[0128] In some embodiments, the air outlet grille 20 has a rearwardly protruding third mating part 26 at the middle of its length direction, and the air outlet 101 has a crossbeam 1113 extending along the width direction of the air outlet grille 20. The crossbeam 1113 has a locking hole 1114. The third mating part 26 can move from front to back to engage with the locking hole 1114, so that the middle of the air outlet grille 20 in the length direction is connected to the crossbeam 1113.

[0129] Therefore, the air vent grille 20 not only cooperates with the air conditioner body 10 at both ends in the length direction, but also cooperates with the air conditioner body 10 in the middle of the length direction, which improves the assembly stability of the air vent grille 20, and can reduce the occurrence of the middle protrusion of the air vent grille 20, reduce the gap between the air vent grille 20 and the air outlet 101, and improve the overall integrity.

[0130] Specifically, during installation, the air outlet grille 20 can be tilted relative to the air conditioner body 10. The second mating part 25 at the upper end of the air outlet grille 20 is inserted into the second insertion hole 172 from bottom to top. Then, the air outlet grille 20 is flipped to fit against the air conditioner body 10, so that the first mating part 24 at the lower end of the air outlet grille 20 is supported by the support part 173 on the air conditioner body 10. The third mating part 26 in the middle of the length direction of the air outlet grille 20 is engaged with the snap hole 1114 on the crossbeam 1113. Finally, the locking member 241 is moved so that the locking member 241 is inserted into the first insertion hole 171, thereby fixing the air outlet grille 20 to the air conditioner body 10, which is convenient for connection.
