[0046] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] The following describes the air guide mechanism 40 according to an embodiment of the present invention with reference to the accompanying drawings.

[0048] Reference Figure 1-Figure 4 According to the air guide mechanism 40 of the first embodiment of the present invention, the air guide mechanism 40 is suitable for being arranged at the air outlet 11 of the air conditioner, and the air guide mechanism 40 includes a connecting rod 41 and at least one air guide louver 42, the connecting rod 41 is rotatably arranged at the air outlet 11, and the rotation axis of the connecting rod 41 extends along the first direction. For example, the above-mentioned air conditioner can be a split air conditioner, the air conditioner includes an air conditioner indoor unit 100 and an air conditioner outdoor unit, the air conditioner indoor unit 100 includes the air outlet 11, and the air guide mechanism 40 is suitable for being arranged at the air outlet 11 of the air conditioner indoor unit 100.

[0049] The air guide louver 42 is fixed to the connecting rod 41 . At least one air guide louver 42 means that the air guide mechanism 40 includes one air guide louver 42 and the air guide louver 42 is fixed to the connecting rod 41 ; or, the air guide mechanism 40 includes multiple air guide louvers 42 and the multiple air guide louvers 42 are all fixed to the connecting rod 41 .

[0050] When there are multiple air guide louvers 42, the multiple air guide louvers 42 are arranged at intervals along the extension direction of the connecting rod 41; wherein, the surface of the air guide louver 42 on at least one side along the thickness direction of the air guide louver 42 forms a guide surface 43, and the guide surface 43 is non-planar, and the air guide louver 42 is driven to rotate by the connecting rod 41 to adjust the air guide direction.

[0051] The guide surface 43 is formed on the surface of at least one side of the air guide louver 42 along the thickness direction of the air guide louver 42, which means that the guide surface 43 is formed on the surface of one side of the air guide louver 42 along the thickness direction of the air guide louver 42; or, the guide surfaces 43 are formed on the surfaces of both opposite sides of the air guide louver 42 along the thickness direction of the air guide louver 42.

[0052] For example, refer to Figure 8According to some embodiments of the present invention, guide surfaces 43 are formed on the surfaces of the air guide louvers 42 on opposite sides along the thickness direction of the air guide louvers 42, and the two guide surfaces 43 are non-planar and parallel, so that the overall thickness of the air guide louvers 42 is relatively uniform, with a thickness of 2 mm to 3 mm; and the two guide surfaces 43 can both adjust the flow direction of the airflow, resulting in a better air guiding effect.

[0053] The connecting rod 41 is rotated to drive the air guide louver 42 to rotate, and the air guide direction is adjusted by rotating the air guide louver 42, so that the blowing direction of the airflow at the air outlet 11 can be adjusted to meet different needs of users.

[0054] The guide surface 43 of the air guide louver 42 can guide the direction of the air flow at the air outlet 11. The guide surface 43 is a non-planar surface. For example, the guide surface 43 can be a curved surface, or the guide surface 43 can be a combination of a curved surface and a flat surface. Therefore, when the air flow flows along the guide surface 43, the guide surface 43 can adjust the flow direction of the air flow, and has a better air guiding effect.

[0055] For example, when the air conditioner is heating, the air guide louver 42 can adjust the airflow to outlet downward, and the air supply range is large, so that the airflow can quickly exchange heat with the indoor air, so as to achieve the purpose of rapid heating, and improve the comfort of different areas of the room; when the air conditioner is cooling, the airflow can be adjusted to outlet upward by rotating the air guide louver 42, and the air supply range is large, so that the airflow can quickly exchange heat with the indoor air, so as to achieve the purpose of rapid cooling, and improve the comfort of different areas of the room.

[0056] In this way, by making the guide surface 43 non-planar, the wind guiding effect of the wind guide louver 42 can be achieved, and the wind guide louver 42 can be prevented from excessively blocking the air outlet 11, thereby ensuring the air outlet area at the air outlet 11, thereby ensuring the air outlet volume at the air outlet 11, and adjusting the indoor temperature more quickly.

[0057] According to the air guide mechanism 40 of the embodiment of the present invention, the air guide louver 42 can be driven to rotate by rotating the connecting rod 41. The surface of the air guide louver 42 on at least one side along the thickness direction of the air guide louver 42 forms a guide surface 43. The guide surface 43 is non-planar. When the airflow flows along the guide surface 43, the guide surface 43 can adjust the flow direction of the airflow, and has a good air guiding effect, so as to achieve the purpose of quickly adjusting the indoor temperature and improve the comfort of different indoor areas; it can also avoid the air guide louver 42 from excessively blocking the air outlet 11, and can ensure the air outlet area at the air outlet 11, thereby ensuring the air outlet volume at the air outlet 11, and can adjust the indoor temperature more quickly.

[0058] Reference Figure 8According to some embodiments of the present invention, the connecting rod 41 can rotate around its own central axis e1, and the air guide louver 42 can rotate around the rotation axis of the connecting rod 41. Compared with the related art in which the connecting rod moves to drive the air guide louver to move to adjust the air guide direction, the present application drives the air guide louver 42 to rotate by rotating the connecting rod 41 around its own central axis, which can reduce the requirement for the movement space of the connecting rod 41. The space occupied by the connecting rod 41 during the rotation process is small, and the air guide mechanism 40 as a whole occupies less space.

[0059] Reference Fig. 9 and Fig.10 According to some optional embodiments of the present invention, the connecting rod 41 is provided through the air guide louver 42, and the projection of the air guide louver 42 on the reference plane is the first projection, and the reference plane is a plane perpendicular to the rotation axis of the connecting rod 41, for example, the reference plane can be a horizontal plane. The projection of the connecting rod 41 on the reference plane is the second projection, and the second projection is located within the first projection, and the geometric center of the second projection coincides with or is adjacent to the geometric center of the first projection, thereby, when the air guide louver 42 rotates around the rotation axis of the connecting rod 41, the range of movement is not too large, and it does not occupy too much space, and the requirements for the size of the air outlet 11 can be reduced.

[0060] Preferably, the geometric center of the second projection may coincide with the geometric center of the first projection, so that the movable range of the air guide louver 42 when rotating around the rotation axis of the connecting rod 41 is smaller, which can further reduce the requirement on the size of the air outlet 11.

[0061] Reference Fig. 9 and Fig.10 According to some optional embodiments of the present invention, the shape of the projection of the air guide louver 42 on the reference plane is circular, and the reference plane is a plane perpendicular to the rotation axis of the connecting rod 41, for example, the reference plane can be a horizontal plane. By making the shape of the projection of the air guide louver 42 on the reference plane circular, the range of movement of the air guide louver 42 when rotating is not too large, and it does not occupy too much space, which can reduce the requirement on the size of the air outlet 11.

[0062] Reference Fig.11According to some embodiments of the present invention, the air guide louver 42 includes a first air guide portion 421 and a second air guide portion 422 that are connected, the first air guide portion 421 has a first guide surface 431, the second air guide portion 422 has a second guide surface 432, the guide surface 43 includes the first guide surface 431 and the second guide surface 432, and there is an angle between the first guide surface 431 and the second guide surface 432. For example, the airflow can flow from the first guide surface 431 to the second guide surface 432, and the airflow can also flow from the second guide surface 432 to the first guide surface 431. By defining an angle between the first guide surface 431 and the second guide surface 432, when the airflow flows along the first guide surface 431 and the second guide surface 432, the flow direction of the airflow will change, so that the air guiding effect of the air guide louver 42 is better. While ensuring that the air guide louver 42 can play a role in adjusting the air guiding direction, the air guide louver 42 can further reduce the obstruction of the air outlet 11, further ensuring the air outlet area of ​​the air outlet 11, so as to ensure the air outlet volume at the air outlet 11.

[0063] Reference Fig.11 According to some optional embodiments of the present invention, the angle β between the first guide surface 431 and the second guide surface 432 is an obtuse angle. When the airflow flows along the first guide surface 431 and the second guide surface 432, the flow direction of the airflow will change, and the flow distance of the airflow attached to the guide surface 43 is farther, so that the air guiding effect of the air guide louver 42 is better; in addition, the obstruction of the air outlet 11 by the air guide louver 42 can be further reduced, and the air outlet area of ​​the air outlet 11 can be further guaranteed to ensure the air outlet volume at the air outlet 11.

[0064] Reference Figure 8 and Fig.11 According to some optional embodiments of the present invention, the first guide surface 431 is a plane or a curved surface, and the second guide surface 432 is a plane or a curved surface. For example, the first guide surface 431 is a plane, and the second guide surface 432 is a plane; or, the first guide surface 431 is a plane, and the second guide surface 432 is a curved surface; or, the first guide surface 431 is a curved surface, and the second guide surface 432 is a plane; or, the first guide surface 431 is a curved surface, and the second guide surface 432 is a plane; or, the first guide surface 431 is a curved surface, and the second guide surface 432 is a curved surface.

[0065] Reference Fig.11 The wind guide louver 42 includes a third wind guide portion 423, which is connected between the first wind guide portion 421 and the second wind guide portion 422. The third wind guide portion 423 has a third guide surface 433, which is connected between the first guide surface 431 and the second guide surface 432. The guide surface 43 includes the third guide surface 433, which is a curved surface, which helps to improve the smoothness of the airflow flowing along the guide surface 43.

[0066] Reference Figure 8-Figure 10According to some optional embodiments of the present invention, the connecting rod 41 is rotatable around its own central axis, and the air guide louver 42 is rotatable around the rotation axis of the connecting rod 41, which can reduce the requirement for the movement space of the connecting rod 41. The connecting rod 41 occupies less space during rotation, and the air guide mechanism 40 as a whole occupies less space.

[0067] Reference Figure 8 and Fig.11 The first direction is the up and down direction, the second air guide portion 422 is connected to the bottom of the first air guide portion 421, and when the airflow at the air outlet 11 flows along the first air guide portion 421 to the second air guide portion 422, the airflow can be guided to be discharged downward; when the airflow at the air outlet 11 flows along the second air guide portion 422 to the first air guide portion 421, the airflow can be guided to be discharged upward, thereby adjusting the airflow in different outlet directions to meet different needs of users. For example, when the air conditioner is heating, the connecting rod 41 is rotated so that the air flow flows along the first guide surface 431 to the second guide surface 432, so that the air guide louvers 42 can guide the hot air to be discharged downward, and the hot air is easy to float up, so that the hot air can diffuse upward to adjust the temperature of areas at different heights; when the air conditioner is cooling, the connecting rod 41 is rotated so that the air flow flows along the second guide surface 432 to the first guide surface 431, so that the air guide louvers 42 can guide the cold air to be discharged upward, and the cold air is easy to settle, so that the cold air can diffuse downward to adjust the temperature of areas at different heights.

[0068] In some optional embodiments of the present invention, the projection of the first air guide portion 421 on the reference plane is the third projection, the projection of the second air guide portion 422 on the reference plane is the fourth projection, the third projection and the fourth projection do not overlap, and the reference plane is a plane perpendicular to the rotation axis of the connecting rod 41. Thus, it can be ensured that the airflow is discharged toward the front side of the air outlet 11, and the shielding of the air outlet 11 by the air guide louver 42 can be further reduced, and the air outlet area of ​​the air outlet 11 is further ensured, so as to ensure the air outlet volume at the air outlet 11.

[0069] Reference Figure 8 and Fig.11 In some optional embodiments of the present invention, in the direction from the third projection to the fourth projection (for example, refer to the direction e2 in the attached figure), the first guide surface 431 extends downwardly and the second guide surface 432 extends downwardly and when the airflow at the air outlet 11 flows along the first guide surface 431 to the second guide surface 432, the airflow can be guided to be discharged downwardly; when the airflow at the air outlet 11 flows along the second guide surface 432 to the first guide surface 431, the airflow can be guided to be discharged upwardly. Therefore, the guide surface 43 has a good wind guiding effect, so as to adjust different outlet directions of the airflow to meet different needs of users.

[0070] Reference Fig.11In some optional embodiments of the present invention, the projection of the air guide louver 42 on the reference plane is a first projection, the first projection includes a third projection and a fourth projection, and in the direction from the third projection to the fourth projection, the extension length of the first projection is L, and the range of L is 60 mm to 80 mm. For example, L can be 60 mm, 65 mm, 70 mm, 75 mm or 80 mm.

[0071] By setting L to be no greater than 80 mm, the movable range of the air guide louver 42 during rotation will not be too large and will not take up too much space, thereby reducing the requirement on the size of the air outlet 11. By setting L to be no less than 60 mm, the extension length of the guide surface 43 in the direction from the third projection to the fourth projection can be ensured, so that the guide distance of the guide surface 43 is longer and the guide effect is better. When the air conditioner is heating, the hot air can be ensured to fall to the ground smoothly, which helps to reduce the temperature difference in different height areas of the indoor space and improve comfort.

[0072] Reference Fig.11 In some optional embodiments of the present invention, the projection of the air guide louver 42 on the reference plane is a first projection, the first projection includes a third projection and a fourth projection, in the direction from the third projection to the fourth projection, the extension length of the first projection is L, the extension length of the third projection is L1, L1, L satisfy: 0≤L1≤2L / 3. L1, L satisfy: 0≤L1≤2L / 3, which means that in the direction from the third projection to the fourth projection, the extension length L1 of the third projection is not greater than 2 / 3 of the extension length L of the first projection, for example, the extension length L1 of the third projection is equal to 1 / 3 of the extension length L of the first projection.

[0073] In the direction from the third projection to the fourth projection, the extension length L1 of the third projection is not greater than 2 / 3 of the extension length L of the first projection, so that the extension length of the fourth projection is not too small. In this way, the guide distance of the second guide surface 432 is longer and the guide effect is better. When the air conditioner is heating, the downward wind guide effect is better, which can ensure that the hot air falls smoothly, reduce the temperature difference in the vertical direction of the indoor space, and improve comfort.

[0074] Reference Fig.11 In some optional embodiments of the present invention, the projection of the air guide louver 42 on the reference surface is a first projection, the first projection includes a third projection and a fourth projection, in the direction from the third projection to the fourth projection, the extension length of the first projection is L, the extension length of the fourth projection is L2, L2, L meet: 0≤L2≤2L / 3. L2, L meet: 0≤L2≤2L / 3, which means that in the direction from the third projection to the fourth projection, the extension length L2 of the fourth projection is not greater than 2 / 3 of the extension length L of the first projection, for example, the extension length L2 of the fourth projection is equal to 2 / 3 of the extension length L of the first projection.

[0075] In the direction from the third projection to the fourth projection, the extension length L2 of the fourth projection is not greater than 2 / 3 of the extension length L of the first projection, so that the second guide surface 432 can be ensured to have a longer guide distance, so that the second guide surface 432 has a better effect of guiding the wind downward, and when the air conditioner is heating, it can ensure that the hot air falls smoothly to the ground, reduce the temperature difference in the vertical direction of the indoor space, and improve comfort; and the extension length of the third projection is not too small, so that the first guide surface 431 can better cooperate with the second guide surface 432 to adjust the outlet direction of the airflow to meet the different needs of users.

[0076] Reference Fig.11 According to some optional embodiments of the present invention, the angle α1 between the first guide surface 431 and the horizontal plane is 0°~15°. For example, when the first guide surface 431 is a plane, the angle α1 between the first guide surface 431 and the horizontal plane is 0°~15°; when the first guide surface 431 is a curved surface, the angle α1 between the tangent plane of the first guide surface 431 and the horizontal plane is 0°~15°. For example, the angle α1 between the tangent plane of the end of the first guide surface 431 away from the second guide surface 432 and the horizontal plane is 0°~15°. α1 can be 2°, 5°, 7°, 10° or 12°.

[0077] By ensuring that the angle α1 between the first guide surface 431 and the horizontal plane is no greater than 15°, it is possible to avoid the first air guide portion 421 from tilting downward too much and causing excessive blocking of the air outlet 11, thereby ensuring the air outlet area at the air outlet 11 and the air outlet volume of the air conditioner at the air outlet 11; and the first guide surface 431 has a better rectifying effect.

[0078] Reference Fig.11 , the angle α2 between the second guide surface 432 and the horizontal plane is 30° to 60°. For example, when the second guide surface 432 is a plane, the angle α2 between the second guide surface 432 and the horizontal plane is 30° to 60°; when the second guide surface 432 is a curved surface, the angle α2 between the tangent plane of the second guide surface 432 and the horizontal plane is 30° to 60°, for example, the angle α2 between the tangent plane of the end of the second guide surface 432 away from the first guide surface 431 and the horizontal plane is 30° to 60°, and α2 can be 30°, 34°, 40°, 45° or 50°.

[0079] By ensuring that the angle α2 between the second guide surface 432 and the horizontal plane is not greater than 60°, it is possible to avoid the second air guide portion 422 from tilting downward at too large an angle and causing excessive obstruction of the air outlet 11, thereby ensuring the air outlet area at the air outlet 11 and the air outlet volume of the air conditioner at the air outlet 11; by ensuring that the angle α2 between the second guide surface 432 and the horizontal plane is not less than 30°, the air guiding effect of the second guide surface 432 can be ensured, so that the second guide surface 432 has a better effect of guiding air downward, and when the air conditioner is heating, it can ensure that the hot air falls to the ground smoothly, thereby reducing the temperature difference between different height areas in the indoor space and improving comfort.

[0080] Therefore, by setting the included angle α2 between the second guide surface 432 and the horizontal plane to 30°~60°, the wind guiding effect of the second guide surface 432 can be ensured, and when the air conditioner is heating, the hot air can be ensured to fall to the ground smoothly and the temperature difference in the vertical direction of the indoor space can be reduced. At the same time, the second air guide part 422 can be prevented from excessively blocking the air outlet 11, so as to ensure the air outlet area at the air outlet 11 and the air outlet volume of the air conditioner at the air outlet 11.

[0081] According to some optional embodiments of the present invention, the air guide louver 42 has a first air guide position. In the first air guide position, the guide surface 43 faces away from the air outlet 11, and the airflow is suitable for flowing from the first guide surface 431 to the second guide surface 432. The second air guide portion 422 is connected to the lower part of the first air guide portion 421, and the second guide surface 432 can be located below the first guide surface 431. The airflow is suitable for flowing from the first guide surface 431 to the second guide surface 432, so that the airflow can be guided to flow downward. When the air conditioner is heating, the airflow at the air outlet 11 is discharged downward, which can heat up the area at a lower position of the indoor space. According to the principle that hot air floats, the area at a higher position of the indoor space can also be heated, thereby reducing the temperature difference between areas at different heights, thereby improving the overall comfort of the indoor space.

[0082] In some optional embodiments of the present invention, the wind guide louver 42 also has at least one of a second wind guide position and a third wind guide position, for example, the wind guide louver 42 also has a second wind guide position; or, the wind guide louver 42 also has a third wind guide position; or, the wind guide louver 42 also has a second wind guide position and a third wind guide position.

[0083] In the second air guiding position, the guide surface 43 faces the air outlet 11, and the airflow is suitable for flowing from the second guide surface 432 to the first guide surface 431. The second air guiding portion 422 is connected to the bottom of the first air guiding portion 421. The second guide surface 432 can be located below the first guide surface 431. The airflow flows from the second guide surface 432 to the first guide surface 431, so as to guide the airflow to flow upward. When the air conditioner is cooling, the airflow at the air outlet 11 is discharged upward, which can cool the higher area of ​​the indoor space. According to the principle of cold air sedimentation, the lower area of ​​the indoor space can also be cooled, thereby reducing the temperature difference between areas at different heights, thereby improving the overall comfort of the indoor space.

[0084] In the third air guiding position, the guide surface 43 faces the side wall of the air outlet 11, and the airflow is suitable for flowing out of the air outlet 11 along the first guide surface 431 and the second guide surface 432 at the same time. With the guide surface 43 facing the side wall of the air outlet 11, the air guide louver 42 has less obstruction to the air outlet 11, and the air outlet 11 has a larger air outlet area. In this way, the airflow flows out of the air outlet 11 along the first guide surface 431 and the second guide surface 432 at the same time, and horizontal air supply can be achieved, which can increase the air outlet volume at the air outlet 11.

[0085] Reference Figure 1 , Figure 8 and Fig.11 In some optional embodiments of the present invention, the connecting rod 41 is rotatable around its own central axis, and the air guide louver 42 is rotatable around the rotation axis of the connecting rod 41, and the rotation axis of the connecting rod 41 extends along the first direction; the air outlet 11 extends along the first direction and the extension length is H, and the extension length of the air guide louver 42 in the first direction is H1, and H1 and H satisfy: 0.04≤H1 / H≤0.07.

[0086] For example, the air outlet 11 extends in the up and down directions. When the extension length H of the air outlet 11 along the first direction is 910 mm, H1 is 36 mm to 64 mm, and H1 is preferably 40 mm to 60 mm. For example, H1 can be 45 mm, 48 mm, 50 mm, 55 mm, 58 mm or 60 mm.

[0087] It can be understood that, when the extension length H of the air outlet 11 along the first direction is constant, the larger the extension length H1 of the air guide louver 42 in the first direction is, the easier it is to block the air outlet 11, reducing the air outlet area, thereby affecting the air outlet volume; if the extension length H1 of the air guide louver 42 in the first direction is too small, when the air conditioner is heating, the air guide louver 42 guides the airflow to flow downward for a shorter distance, and the hot air has a longer distance before it falls to the ground, increasing the time it takes for the hot air to fall to the ground. It is easy to dissipate in the process of hot air flow and diffusion, and the hot air floats, resulting in poor heating effect in lower areas of the indoor space and large temperature difference between different height areas of the indoor space.

[0088] Therefore, by setting 0.04≤H1 / H≤0.07, H1 will not be too large, and the air outlet area at the air outlet 11 can ensure the air outlet volume; and H1 will not be too small, and the air guide louver 42 can guide the airflow to flow downward for a longer distance, thereby reducing the landing time of the hot air, ensuring the heating effect of the lower position area of ​​the indoor space, and reducing the temperature difference between different height areas of the indoor space.

[0089] Reference Figure 1 and Figure 8 According to some embodiments of the present invention, the connecting rod 41 is rotatable around its own central axis, the air guide louver 42 is rotatable around the rotation axis of the connecting rod 41, the air outlet 11 extends along the first direction and the extension length is H, the connecting rod 41 extends along the first direction, and along the first direction, among two adjacent air guide louvers 42, the distance between the lowest point of the air guide louver 42 located on the upper side and the highest point of the air guide louver 42 located on the lower side is H2, and H2 and H satisfy: 0.045≤H2 / H≤0.085.

[0090] For example, when the extension length H of the air outlet 11 along the first direction is 910 mm, H2 is 40 mm to 77 mm, and H2 is preferably 50 mm to 75 mm. For example, H2 may be 55 mm, 57 mm, 60 mm, 65 mm, 70 mm or 75 mm.

[0091] It is understandable that, when the extension length H of the air outlet 11 along the first direction is constant, the larger the distance H2 between the lowest point of the upper air guide louver 42 and the highest point of the lower air guide louver 42 of two adjacent air guide louvers 42, the fewer the number of air guide louvers 42 that can be accommodated by the air outlet 11, which easily leads to a decrease in the wind speed at the air outlet 11, increases the difficulty of hot air falling to the ground, and increases the temperature difference between different height areas in the indoor space. However, when H2 is too small, the number of air guide louvers 42 at the air outlet 11 is large, which easily blocks the air outlet 11, reduces the air outlet area, and thus affects the air volume.

[0092] Therefore, by adjusting 0.05≤H2 / H≤0.085, H2 is not too large, so as to ensure that the number of air guide louvers 42 at the air outlet 11 of different sizes can be within an appropriate range, thereby avoiding affecting the wind speed and air outlet area at the air outlet 11. When the air conditioner is heating, it can reduce the difficulty of hot air falling to the ground, reduce the temperature difference between different height areas in the indoor space, and ensure the air outlet volume at the air outlet 11.

[0093] Reference Figure 1-Figure 3The air conditioner according to the second embodiment of the present invention comprises: a casing 10, a heat exchanger component 20, an air duct component 30 and an air guide mechanism 40, the casing 10 having an air inlet and an air outlet 11; the heat exchanger component 20 and the air duct component 30 are arranged in the casing 10; the air guide mechanism 40 is the air guide mechanism 40 of the first embodiment of the present invention, and the air guide mechanism 40 is arranged at the air outlet 11 to adjust the air outlet.

[0094] The air conditioner may be a split floor-standing air conditioner, and the air conditioner may include an air conditioner indoor unit 100 and an air conditioner outdoor unit. For example, the air conditioner indoor unit 100 may be a cabinet unit, and the air conditioner indoor unit 100 includes the above-mentioned housing 10, a heat exchanger component 20, an air duct component 30, and an air guide mechanism 40. The air inlet is located at the rear side of the housing 10, and the air outlet 11 is formed at the front side of the housing 10 and is arranged in two intervals along the left and right directions. The heat exchanger component 20 is arranged at the front side of the air inlet, and the air duct component 30 is arranged between the heat exchanger component 20 and the air outlet 11. The air duct component 30 has an air duct cavity 32 and two crossflow impellers 33 arranged in the air duct cavity 32. The air outlet 11 is connected to the air duct cavity 32.

[0095] For example, the air conditioner indoor unit 100 further includes a switch door 12, which is rotatably arranged at the air outlet 11 to open and close the air outlet 11. The switch door 12 can also adjust the outlet direction of the airflow at the air outlet 11, for example, it can guide the airflow to be discharged in the left and right directions. Two switch doors 12 are arranged at each air outlet 11, and the switch doors 12 have an open position and a closed position. When the switch door 12 is in the open position, the air outlet 11 is opened, and the air at the air inlet enters the housing 10 under the drive of the crossflow impeller 33 and exchanges heat with the heat exchanger component 20. The airflow after heat exchange enters the air duct cavity 32 and is blown into the room through the air outlet 11; when the switch door 12 is in the closed position, the air outlet 11 is closed. During the process of switching from the closed position to the open position, the two switch doors 12 in the same air outlet 11 rotate in the direction away from each other, and the rotation angles of the two switch doors 12 are both 45° to 55°; during the process of switching from the open position to the closed position, the two switch doors 12 in the same air outlet 11 rotate in the direction close to each other, and the rotation angles of the two switch doors 12 are both 45° to 55°.

[0096] For example, according to some optional embodiments of the present invention, the air conditioner may have a cooling mode, a heating mode and an air supply mode. In the cooling mode, the switch door 12 may be in an open position, the air guide louver 42 may be in a second air guide position, the guide surface 43 faces the air outlet 11, and the airflow may flow from the second guide surface 432 to the first guide surface 431, so that the airflow at the air outlet 11 is discharged upward; in addition, the switch door 12 may also be moved between an open position and a closed position, and the air guide louver 42 may also be rotated 360° around the rotation axis of the connecting rod 41. During the rotation of the air guide louver 42, the airflow may flow from the second guide surface 432 to the first guide surface 431, or from the first guide surface 431 to the second guide surface 432, or flow along the first guide surface 431 and the second guide surface 432 at the same time, so that the airflow may be guided left and right while the airflow may be guided up and down and horizontally supplied. In the heating mode, the switch door 12 can be in the open position, the air guide louver 42 can be in the first air guide position, the guide surface 43 is facing away from the air outlet 11, the airflow can flow from the first guide surface 431 to the second guide surface 432, and the airflow at the air outlet 11 is discharged downward; in addition, the switch door 12 can also move between the open position and the closed position, and the air guide louver 42 can also rotate 360° around the rotation axis of the connecting rod 41. During the rotation of the air guide louver 42, the airflow can flow from the second guide surface 432 to the first guide surface 431, and the airflow can also flow from the first guide surface 431 to the second guide surface 432. The airflow can also flow along the first guide surface 431 and the second guide surface 432 at the same time, so that the airflow can be guided left and right while the upward and downward airflow and horizontal air supply can be achieved. In the air supply mode, the switch door 12 can be in the open position, and the air guide louver 42 can be located at the third air guide position to achieve horizontal air supply; in addition, the switch door 12 can also move between the open position and the closed position, and the air guide louver 42 can also rotate 360° around the rotation axis of the connecting rod 41. In this way, while achieving left and right air flow guidance, up and down air guidance and horizontal air supply can be achieved.

[0097] According to the air conditioner of the embodiment of the present invention, by setting the above-mentioned air guide mechanism 40, the air guide louver 42 can be driven to rotate by rotating the connecting rod 41, and the surface of the air guide louver 42 on at least one side of the thickness direction of the air guide louver 42 forms a guide surface 43, and the guide surface 43 is a non-planar surface. When the airflow flows along the guide surface 43, the guide surface 43 can adjust the flow direction of the airflow, and has a good air guiding effect, so as to achieve the purpose of quickly adjusting the indoor temperature and improve the comfort of different indoor areas; it can also avoid the air guide louver 42 from excessively blocking the air outlet 11, and can ensure the air outlet area at the air outlet 11, thereby ensuring the air outlet volume at the air outlet 11, and can adjust the indoor temperature more quickly.

[0098] Refer to the following Figure 1-Figure 11The wind guide mechanism 40 according to one embodiment of the present invention will be described.

[0099] Reference Figure 1-Figure 11 The air guide mechanism 40 is used for an air conditioner, which is a split floor-standing air conditioner. The air conditioner includes an air conditioner indoor unit 100 and an air conditioner outdoor unit. The air conditioner indoor unit 100 is a cabinet unit and the air guide mechanism 40 is arranged at the air outlet 11 of the air conditioner indoor unit 100. The air guide mechanism 40 includes a connecting rod 41 and a plurality of air guide louvers 42. The connecting rod 41 is rotatably arranged at the air outlet 11. The connecting rod 41 is rotatable along its own central axis. The rotation axis of the connecting rod 41 extends along a first direction, and the first direction is an up-and-down direction.

[0100] A plurality of air guide louvers 42 are fixed to the connecting rod 41, and the plurality of air guide louvers 42 are arranged at intervals along the extension direction of the connecting rod 41. The surfaces of the air guide louvers 42 on opposite sides along the thickness direction of the air guide louvers 42 form guide surfaces 43. Both guide surfaces 43 are non-planar and parallel. The thickness of the air guide louvers 42 is 2 mm to 3 mm. The air guide louvers 42 are driven to rotate by the connecting rod 41 to adjust the air guide direction. The air guide louvers 42 can rotate around the rotation axis of the connecting rod 41.

[0101] The connecting rod 41 is inserted through the air guide louver 42. The projection of the air guide louver 42 on the reference plane is a first projection.

The guide surface 43 includes a first guide surface 431, a second guide surface 432 and a third guide surface 433. There is an angle β between the first guide surface 431 and the second guide surface 432, and the angle β between the first guide surface 431 and the second guide surface 432 is an obtuse angle; the first guide surface 431 is a plane, the second guide surface 432 is a plane, and the third guide surface 433 is a curved surface. An included angle α1 between the first guide surface 431 and the horizontal plane is 0° to 15°, and an included angle α2 between the second guide surface 432 and the horizontal plane is 30° to 60°.

[0103] The projection of the first air guide portion 421 on the reference surface is the third projection, and the projection of the second air guide portion 422 on the reference surface is the fourth projection. The third projection does not overlap with the fourth projection, and the first projection includes the third projection and the fourth projection. In the direction from the third projection to the fourth projection, the first guide surface 431 extends obliquely downward, and the second guide surface 432 extends obliquely downward. In the direction from the third projection to the fourth projection, the extension length of the first projection is L, and the range of L is 60mm to 80mm; the extension length of the third projection is L1, and L1 and L satisfy: 0≤L1≤2L / 3; the extension length of the fourth projection is L2, and L2 and L satisfy: 0≤L2≤2L / 3.

[0104] The wind guide louver 42 has a first wind guide position, a second wind guide position and a third wind guide position. In the first wind guide position, the guide surface 43 faces away from the air outlet 11, and the airflow is suitable for flowing from the first guide surface 431 to the second guide surface 432; in the second wind guide position, the guide surface 43 faces the air outlet 11, and the airflow is suitable for flowing from the second guide surface 432 to the first guide surface 431; in the third wind guide position, the guide surface 43 faces the side wall of the air outlet 11, and the airflow is suitable for flowing out of the air outlet 11 along the first guide surface 431 and the second guide surface 432 at the same time.

[0105] The air outlet 11 extends along the first direction and the extension length is H.

[0106] Reference Fig.12 , Fig.12 The comparison between the numerical simulation of the air guiding effect of the air guiding mechanism 40 of the embodiment of the present invention and the air guiding effect of the air guiding mechanism in the related art is shown. Figure 12-1 When the air conditioner in the related technology is heating, the air guide louvers at the air outlet extend downward, and the air flow generates a large vortex between two adjacent air guide louvers, which reduces the effective flow area of ​​the air outlet and the air volume. The wind speed at the air outlet is low, and the hot air escapes after flowing out of the air outlet. The hot air delivery distance is too short, resulting in the hot air being unable to fall to the ground, which in turn leads to a large temperature difference in different height areas of the indoor space, reducing the heating comfort of the air conditioner.

[0107] Reference Figure 12-2The air guide louver 42 designed according to the above parameters (α1=0°~15°, α2=30°~60°, 0≤L1≤2L / 3, 0≤L2≤2L / 3, L=60mm~80mm, and H1=50mm~75mm) is used for the air conditioner. When the air conditioner is heating, the first guide surface 431 has a rectifying effect, so that the eddy current between two adjacent air guide louvers 42 is significantly reduced, the effective flow area of ​​the air outlet 11 is larger, the air volume and wind speed at the air outlet 11 are better than those of the air conditioner in the related art, the hot air is sent out over a longer distance, and the hot air is easier to land, which can effectively reduce the temperature difference between different height areas in the indoor space and improve the heating comfort of air conditioning.

[0108] The method for testing the temperature difference is as follows: first, the temperature of multiple points can be tested on a horizontal plane with a height of 0.1m in the indoor space, and the average temperature T1 of the multiple points can be calculated; and the temperature of multiple points can be tested on a horizontal plane with a height of 1.7m in the indoor space, and the average temperature T2 of the multiple points can be calculated; finally, the temperature difference between the area with a height of 1.7m in the indoor space and the area with a height of 0.1m can be obtained by calculating the difference between T1 and T2.

[0109] When the air conditioner in the related technology is heating, the temperature difference between the area with a height of 1.7m in the indoor space and the area with a height of 0.1m is 8.16°; when the air conditioner in the embodiment of the present invention is heating, the temperature difference between the area with a height of 1.7m in the indoor space and the area with a height of 0.1m is 3.53°, which effectively reduces the temperature difference between areas of different heights in the indoor space to improve comfort.
