[0033] The following describes embodiments of the present invention in detail. Examples of the embodiments 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0034] Reference below Figures 1-8 An air conditioner according to an embodiment of the present invention is described.

[0035] Reference Figure 1-Figure 3According to an embodiment of the present invention, the air conditioner includes a casing 1, a heat exchanger assembly 2, an air duct assembly 3 and an air guide component 4. The casing 1 is formed with an air inlet 12 and an air outlet 11. The air outlet 11 is located on the front side of the casing 1, the heat exchanger assembly 2 is arranged in the casing 1, the air duct assembly 3 is arranged in the casing 1 and the air duct assembly 3 is located between the heat exchanger assembly 2 and the air outlet 11. The air duct assembly 3 includes an air duct volute 31, a wind wheel 32 and an air outlet frame 33. The air duct volute 31 has an air duct 311, at least part of the wind wheel 32 is located in the air duct 311, the air outlet frame 33 is connected to the downstream side of the air duct volute 31 and the air outlet frame 33 has an air outlet channel 332 connected to the air duct 311, the air guide component 4 is rotatably connected to the air outlet frame 33 and the air guide component 4 is located in the air outlet channel 332, and the rotation axis of the air guide component 4 extends in the up and down direction.

[0036] When the air conditioner is operating, the impeller 32 can drive airflow through the air inlet 12 into the housing 1 and toward the heat exchanger assembly 2. After heat exchange in the heat exchanger assembly 2, the air can flow through the air duct 311 within the air duct volute 31 to the air outlet duct 332, and then be blown out into the room through the air outlet 11 to cool or heat the room. The air guide component 4 is located within the air outlet duct 332 and can guide the airflow within the air outlet duct 332, allowing the airflow to flow more smoothly toward the air outlet 11, reducing losses during the flow process and facilitating increased airflow. Furthermore, the air guide component 4 is rotatably connected to the air outlet frame 33. By adjusting the rotation amplitude of the air guide component 4, the direction of the airflow at the air outlet 11 can be adjusted.

[0037] Among them, the plane where the air flow outlet 3322 of the air outlet channel 332 is located is the air outlet surface, the width of the air outlet surface in the left and right direction is L2, the rotation axis of the air guide component 4 is located on the rear side of the air outlet surface and the distance between the rotation axis of the air guide component 4 and the air outlet surface in the front and rear direction is D4, 0.05*L2≤D4≤0.3*L2.

[0038] For example, D4 ​​can be 0.05*L2, 0.12*L2, 0.22*L2, 0.25*L2, 0.3*L2, etc. When D4≥0.05*L2, the space between the rotation axis of the air-guiding component 4 and the air outlet surface can be made large enough. For example, the driving mechanism for driving the air-guiding component 4 to rotate is the first driving mechanism, which can facilitate the first driving mechanism to be accommodated in this part of the space between the rotation axis of the air-guiding component 4 and the air outlet surface; when D4≤0.3*L2, the air-guiding effect of the air-guiding component 4 can be guaranteed, and the distance between the rotation axis of the air-guiding component 4 and the air outlet surface in the front-to-back direction is avoided to be too large, which makes the position of the air-guiding component 4 in the front-to-back direction too far back. The position of the air-guiding component 4 in the front-to-back direction is too far back, which will weaken the air-guiding effect of the air-guiding component 4.

[0039] For example, the first drive mechanism is provided on the casing 1 and the first drive mechanism and the air guide component 4 are arranged in sequence in the up and down directions. By D4≥0.05*L2, the space between the rotation axis of the air guide component 4 and the air outlet surface can be made large enough, and then the corresponding space on the casing 1 component can be made large enough, so that the assembly space of the first drive mechanism is large enough to facilitate the first drive mechanism to be accommodated therein, and the air guide component 4 can be avoided from being too close to the front. For example, a switch door for opening and closing the air outlet 11 is provided at the air outlet 11. By D4≥0.05*L2, the position of the air guide component 4 can be avoided from being too close to the front and interfering with the switch door.

[0040] By satisfying 0.05*L2≤D4≤0.3*L2, the space between the rotation axis of the air guide component 4 and the air outlet surface is large enough to accommodate the first driving mechanism in this space, and the air guiding effect of the air guide component 4 can be better guaranteed.

[0041] According to the air conditioner of the embodiment of the present invention, the plane where the air flow outlet 3322 through the air outlet channel 332 is located is the air outlet surface, the width of the air outlet surface in the left and right direction is L2, and the distance D4 between the rotation axis of the air guide component 4 and the air outlet surface in the front-to-back direction satisfies 0.05*L2≤D4≤0.3*L2, so that the space between the rotation axis of the air guide component 4 and the air outlet surface can be large enough so that the first driving mechanism for driving the air guide component 4 can be accommodated in this part of the space between the rotation axis of the air guide component 4 and the air outlet surface, and the position of the air guide component 4 in the front-to-back direction can be made more reasonable, avoiding interference with the opening and closing door at the air outlet 11 due to the air guide component 4 being too far forward in the front-to-back direction, and also avoiding weakening the air guiding effect of the air guide component 4 due to the air guide component 4 being too far back in the front-to-back direction.

[0042] Reference Figure 2-Figure 4 According to some embodiments of the present invention, an escape groove 335 is formed on the inner wall of the air outlet channel 332 for evading the air guide component 4. The escape groove 335 can be used to avoid the air guide component 4, allowing the air guide component 4 to rotate more smoothly and preventing the air guide component 4 from interfering with the inner wall of the air outlet channel 332.

[0043] By setting D4≤0.3*L2, it is possible to avoid the space between the rotation axis of the air guide component 4 and the air outlet surface being too large. If the space between the rotation axis of the air guide component 4 and the air outlet surface is too large, the overall size of the air guide component 4 will be too large, and the avoidance groove 335 used to avoid the air guide component 4 will be too large. If the avoidance groove 335 is too large, the flow cross-section of the air outlet channel 332 will suddenly become too large, thereby causing surging due to sudden changes in airflow. By setting D4≤0.3*L2, the flow cross-section of the air outlet channel 332 can be made smaller to reduce the surging due to sudden changes in airflow.

[0044] Optionally, refer to Figure 3 The air outlet channel 332 extends obliquely to the left from the back to the front, and the air duct volute 31 includes a front volute tongue 312, which is located in front of the wind wheel 32. The wall of the front volute tongue 312 facing the air duct 311 includes a first volute tongue wall 3121 and a second volute tongue wall 3122 arranged at an angle, and the second volute tongue wall 3122 is connected to the downstream side of the first volute tongue wall 3121 and includes a planar first air duct profile 3123.

[0045] The air outlet channel 332 has a second air duct profile 333 arranged opposite to the second volute tongue wall 3122. The diameter of the wind wheel 32 is D. The circle obtained with the center of the wind wheel 32 as the center and a diameter of 1.45D is the first reference circle. The intersection of the first reference circle and the first air duct profile 3123 is the intersection A. A perpendicular line g is drawn with the intersection A as the foot of the perpendicular. The intersection of the perpendicular line g and the second air duct profile 333 is the intersection B. The line segment formed by the line connecting the intersection A and the intersection B is the line segment AB, and the length of the line segment AB is L1.

[0046] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the duct volute 31 includes a front volute tongue 312, which is located in front of the wind wheel 32. The wall of the front volute tongue 312 facing the duct 311 includes a first volute tongue wall surface 3121 and a second volute tongue wall surface 3122 arranged at an angle. The second volute tongue wall surface 3122 is connected to the downstream side of the first volute tongue wall surface 3121 and includes a first duct profile surface 3123 in a plane. The air outlet channel 332 has a second duct profile surface 333 arranged opposite to the second volute tongue wall surface 3122. The diameter of the wind wheel 32 is D, and a circle obtained by taking the center of the wind wheel 32 as the center and xD as the diameter is the first duct profile surface 3123. Reference circle, 1.35≤x≤1.55, the intersection of the first reference circle and the first air duct profile 3123 is intersection A, a perpendicular line g is drawn with intersection A as the foot of the perpendicular, the intersection of the perpendicular line g and the second air duct profile 333 is intersection B, the line segment formed by the line connecting intersection A and intersection B is line segment AB, the length of line segment AB is L1, in the horizontal direction, the point on the air guide component 4 that is farthest from the rotation axis of the air guide component 4 is point C, the circle obtained with the rotation center of the air guide component 4 as the center and passing through point C is the second reference circle, the diameter of the second reference circle is D5, 1.1*L1≤D5≤0.95*L2, where L1 is smaller than L2.

[0047] For example, x can be 1.35, 1.4, 1.45, 1.5, 1.55, etc., and through 1.1*L1≤D5≤0.95*L2, the overall size of the air guide component 4 is moderate to better meet the left air guide effect and the right air guide effect of the air guide component 4, while avoiding the air guide component 4 from interfering with the side wall of the air outlet channel 332 during rotation.

[0048] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the duct volute 31 includes a front volute tongue 312, which is located in front of the wind wheel 32. The wall of the front volute tongue 312 facing the duct 311 includes a first volute tongue wall 3121 and a second volute tongue wall 3122 arranged at an angle. The second volute tongue wall 3122 is connected to the downstream side of the first volute tongue wall 3121 and includes a first duct profile 3123 in a plane. The air outlet channel 332 has a second duct profile 333 arranged opposite to the second volute tongue wall 3122. The diameter of the wind wheel 32 is D, and the center of the wind wheel 32 is the center of the circle and 1.45D is the diameter. The obtained circle is the first reference circle, the intersection of the first reference circle and the first air duct profile 3123 is the intersection A, the perpendicular line g is drawn with the intersection A as the foot of the perpendicular, the intersection of the perpendicular line g and the second air duct profile 333 is the intersection B, the line segment formed by the line connecting the intersection A and the intersection B is the line segment AB, the length of the line segment AB is L1, in the horizontal direction, the point on the air guide component 4 that is farthest from the rotation axis of the air guide component 4 is point C, the circle obtained with the rotation center of the air guide component 4 as the center and passing through point C is the second reference circle, the diameter of the second reference circle is D5, 1.1*L1≤D5≤0.95*L2, where L1 is smaller than L2.

[0049] For example, the diameter D5 of the second reference circle can be 1.1*L1, 0.95*L2, etc. By setting D5≥1.1*L1, the overall size of the air guide component 4 is large enough to better meet the left air guiding effect and the right air guiding effect of the air guide component 4, and avoid the air guiding effect of the air guide component 4 on the airflow being weakened due to the distance between the farthest point on the air guide component 4 and the rotation axis of the air guide component 4 being too small; by setting D5≤0.95*L2, the rotation process of the air guide component 4 is smoother, and avoid the overall size of the air guide component 4 being too large, which causes the air guide component 4 to interfere with the side wall of the air outlet channel 332 during rotation.

[0050] By setting 1.1*L1≤D5≤0.95*L2, the overall size of the air guide component 4 is moderate, so as to better meet the left air guide effect and the right air guide effect of the air guide component 4, while avoiding interference between the air guide component 4 and the side wall of the air outlet channel 332 during rotation.

[0051] Reference Figure 7According to some embodiments of the present invention, the air guide component 4 includes an air guide grille 45, which includes a plurality of spaced-apart grille ribs 451 extending in the vertical direction, with guide channels 452 defined between adjacent grille ribs 451. The spaced-apart arrangement of the plurality of grille ribs 451 can enhance the overall structural strength of the air guide grille 45 to a certain extent. The spaced-apart arrangement of the plurality of grille ribs 451 and the guide channels 452 defined between adjacent grille ribs 451 can guide the airflow through the air guide grille 45 and achieve more uniform airflow distribution.

[0052] In the description of the present invention, “plurality” means two or more.

[0053] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, the air guide component 4 has a left air guide position for guiding air toward the left front and a right air guide position for guiding air toward the right front. In the left air guide position, the air guide grille 45 is used to guide air toward the left front, and in the right air guide position, the air guide grille 45 is used to guide air toward the right front. When the air guide component 4 is rotated to the left air guide position, the air guide grille 45 can be adjusted to guide the airflow toward the left front, and the airflow flows toward the left front of the air outlet 11 through the guide channel 452. When the air guide component 4 is rotated to the right air guide position, the air guide grille 45 can be adjusted to guide the airflow toward the right front, and the airflow flows toward the right front of the air outlet 11 through the guide channel 452.

[0054] Reference Figure 2-Figure 4 According to some embodiments of the present invention, the air guide member 4 has a left air guide position for guiding air toward the left front and a right air guide position for guiding air toward the right front. The air guide member 4 also has a front air guide position. In the front air guide position, the air guide member 4 is used to guide air directly forward.

The air guide grille 45 includes a plurality of spaced-apart grille ribs 451, which extend in the vertical direction. Adjacent grille ribs 451 define a guide channel 452. In the forward air guide position, the air guide grille 45 is configured to guide air forward. When the air guide component 4 is rotated to the forward air guide position, the air guide grille 45 can be adjusted to direct air forward, with the air flowing forward through the guide channel 452.

[0056] Reference Figure 2 According to some embodiments of the present invention, in the front air guiding position, the front-facing side of the air guiding component 4 is the front air guiding side. In the front air guiding position, the maximum distance between the front air guiding side and the air outlet surface in the front-to-back direction is D3, where -0.1*L2≤D3≤0.45*L2. Specifically, in the front air guiding position, when the front air guiding side is located in front of the air outlet surface, the distance between the front air guiding side and the air outlet surface in the front-to-back direction is a positive value; when the front air guiding side is located behind the air outlet surface, the distance between the front air guiding side and the air outlet surface in the front-to-back direction is a negative value.

[0057] For example, D3 can be -0.1*L2, 0.1*L2, 0.2*L2, 0.35*L2, 0.45*L2, etc. By setting D3≥-0.1*L2, the overall size of the air guide component 4 can be made large enough to better meet the left air guide effect and the right air guide effect of the air guide component 4, and avoid the air guide effect of the air guide component 4 on the airflow being weakened due to the distance between the air guide front side and the air outlet surface in the front-to-back direction being too small; by setting D3≤0.45*L2, the rotation process of the air guide component 4 is smoother, and avoid the distance between the air guide front side and the air outlet surface in the front-to-back direction being too large, which causes the air guide component 4 to interfere with the side wall of the air outlet channel 332 during rotation.

[0058] By setting -0.1*L2≤D3≤0.45*L2, the maximum distance between the air-guiding front side of the air-guiding component 4 and the air-outlet surface in the front-to-rear direction is moderate, so as to better meet the left air-guiding effect and the right air-guiding effect of the air-guiding component 4, and at the same time avoid interference between the air-guiding component 4 and the side wall of the air-outlet channel 332 during rotation.

[0059] Reference Figure 6 According to some embodiments of the present invention, the air guide component 4 includes an air guide grille 45 and a louver mechanism 46. The air guide grille 45 is rotatably connected to the air outlet frame 33. The louver mechanism 46 is disposed within the air guide grille 45. The louver mechanism 46 includes a connecting rod 462 and a plurality of louvers 461. The plurality of louvers 461 are arranged in the vertical direction. The plurality of louvers 461 are rotatably connected to the connecting rod 462 and the plurality of louvers 461 are rotatably connected to the air guide grille 45. The louver mechanism 46 is disposed within the air guide grille 45. The air guide grille 45 supports and protects the louver mechanism 46. The louvers 461 are rotatably connected to the air guide grille 45 and the connecting rod 462. The rotation amplitude of the louvers 461 can be adjusted by driving the connecting rod 462, thereby adjusting the flow direction and amount of airflow in the vertical direction.

[0060] Reference Figure 5 and Figure 8According to some embodiments of the present invention, the air guide grille 45 includes a plurality of grille ribs 451 spaced apart from each other. The grille ribs 451 extend in the vertical direction, and adjacent grille ribs 451 define air guide channels 452. At least some of the louvers 461 are formed with clearance notches 464 for circumventing the grille ribs 451. By forming clearance notches 464 for circumventing the grille ribs 451 on at least some of the louvers 461, the space within the air guide grille 45 can be fully utilized, resulting in a compact overall structure of the air guide grille 45 and the louvers 461. The possibility of interference between the louvers 461 and the air guide grille 45 can also be reduced or avoided. Furthermore, the area of ​​the louvers 461 can be increased. The increased area enhances the airflow guiding effect of the louvers 461, thereby further enhancing the overall air guiding effect of the air guide component 4.

[0061] Among them, at least part of the louvers 461 are formed with avoidance gaps 464 for avoiding the grille ribs 451, which may include the following situations: for example, avoidance gaps 464 for avoiding the grille ribs 451 may be formed on part of the louvers 461; for another example, avoidance gaps 464 for avoiding the grille ribs 451 may be formed on all the louvers 461.

[0062] Reference Figure 6 According to some embodiments of the present invention, the air outlet frame 33 includes an air outlet frame body 331 and a partition block 334. The air outlet frame body 331 defines an air outlet channel 332. The partition block 334 is disposed within the air outlet channel 332 to divide the air outlet channel 332 into multiple air outlet zones arranged in a vertical direction. Each of the multiple air outlet zones is provided with a rotatable air guide member 4. The partition block 334 divides the air outlet channel 332 into multiple air outlet zones arranged in a vertical direction, and each air outlet zone is provided with a rotatable air guide member 4, which allows the airflow direction within each air outlet zone to be adjusted separately.

[0063] Reference Figure 6 According to some embodiments of the present invention, the driving mechanism for driving the air guide component 4 to rotate is a first driving mechanism, there are multiple first driving mechanisms, and the number of the first driving mechanisms is the same as that of the air guide components 4, and the first driving mechanisms and the air guide components 4 correspond one-to-one, and each first driving mechanism is connected to the corresponding air guide component 4. The first driving mechanism can drive the air guide component 4 to rotate to adjust the direction of the airflow at the air outlet 11. By having multiple first driving mechanisms, the number of the first driving mechanisms is the same as that of the air guide components 4, and the first driving structure corresponds one-to-one to the air guide components 4, the rotation angle of the air guide component 4 in each air outlet area can be driven separately, and then the independent adjustment of the airflow direction in each air outlet area can be achieved, so that the user can adjust the airflow direction of each air outlet area according to actual conditions, which is conducive to improving the user experience.

[0064] For example, the air guide components 4 in each air outlet area can rotate synchronously; for another example, the air guide components 4 in each air outlet area can rotate differentially in the same direction; for another example, the air guide components 4 in each air outlet area can rotate in different directions.

[0065] Reference Figure 6 According to some embodiments of the present utility model, each air guide component 4 includes an air guide grille 45 and a louver mechanism 46. The air guide grille 45 is rotatably connected to the air outlet frame 33. The louver mechanism 46 is provided on the air guide grille 45. The louver mechanism 46 includes a connecting rod 462 and a plurality of louver blades 461. The plurality of louver blades 461 are arranged in the up and down directions. The plurality of louver blades 461 are rotatably connected to the connecting rod 462 and the louver blades 461 are rotatably connected to the air guide grille 45. The connecting rods 462 in two adjacent air guide components 4 are connected by a connecting column 463. The connecting rods 462 in two adjacent air guide components 4 are rotatably connected to the corresponding connecting column 463. The driving mechanism for driving the louver mechanism 46 to move is a second driving mechanism. The louver mechanisms 46 of multiple air guide components 4 share one second driving mechanism.

[0066] The second drive mechanism can drive the connecting rod 462 to move, thereby adjusting the rotation amplitude of the louver 461, thereby adjusting the flow direction and airflow volume of the airflow through the air guide grille 45, and further adjusting the airflow direction at the air outlet 11. Because the connecting rods 462 in two adjacent air guide components 4 are rotatably connected to the corresponding connecting posts 463, and the louver mechanisms 46 of multiple air guide components 4 share a single second drive mechanism, a single second drive mechanism can be used to drive the louver 461 in multiple air guide components 4 to move synchronously, thereby further adjusting the airflow direction and volume in each air outlet area.

[0067] For example, when the air guide components 4 in adjacent air outlet areas rotate in different directions, the connecting rods 462 in the two adjacent air guide components 4 are rotatably connected to the corresponding connecting columns 463, and a second driving mechanism can also be used to drive the louvers 461 in adjacent air outlet areas to move synchronously.

[0068] Reference Figure 6According to some embodiments of the present invention, the air guide grille 45 has first surfaces 41 on both sides along the vertical direction. A rotating shaft 411 is provided on the first surface 41. The air outlet frame body 331 and the partition block 334 are each provided with a rotating hole. The rotating shaft 411 is rotatably received in the corresponding rotating hole. The rotating shaft 411 has a through-hole 412 for the connecting post 463 to pass through. The rotating hole facilitates the receiving of the rotating shaft 411, thereby facilitating the assembly of the air outlet frame 33 and the air guide grille 45 and making the overall structure of the air outlet frame 33 and the air guide grille 45 more compact. The through-hole 412 facilitates the assembly of the connecting post 463 on the air guide grille 45 and makes the overall structure of the connecting post 463 and the air guide grille 45 more compact.
