[0028] The following describes in detail embodiments of the present invention. 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.

[0029] Reference below Figure 1-Figure 5 An air conditioner according to an embodiment of the present invention is described.

[0030] The air conditioner according to the embodiment of the present invention includes: a casing assembly 2 , a heat exchanger assembly 3 and an air duct assembly 4 .

[0031] For example, the air conditioner is a split-type air conditioner, which is divided into an air conditioner indoor unit 100 and an air conditioner outdoor unit. The air conditioner indoor unit 100 includes a casing component 2, a heat exchange component and an air duct component 4.

[0032] Reference Figure 1-Figure 3 The front of the housing assembly 2 is formed with two air outlets 22 arranged in a left-right direction, and the rear of the housing assembly 2 is formed with an air inlet 21. The heat exchanger assembly 3 is disposed within the housing assembly 2. By providing two air outlets 22 spaced apart in the left-right direction, the air conditioner can adjust the temperature over a wider range of spaces.

[0033] The air duct assembly 4 is disposed within the housing assembly 2 and includes an air duct volute 41 and a fan assembly 44. The air duct volute 41 includes two air ducts 414 arranged in the left-right direction. The two air outlets 22 are respectively connected to the two air ducts 414. The fan assembly 44 includes two fans 444 arranged in the left-right direction. The fans 444 include a wind wheel 441 and a motor 442. The motor 442 is connected to the wind wheel 441. The two wind wheels 441 are respectively located in the two air ducts 414. By making the air duct volute 41 include two front volutes 411 arranged in the left-right direction, and the fan assembly 44 includes two fans 444, and installing the two fans 444 in the two air ducts 414, the air conditioner's air driving ability can be improved, and the air intake and air outlet of the air conditioner can be increased, thereby improving the temperature regulation efficiency. By making the air outlet 22 two air outlets spaced apart in the left-right direction, the air outlet range of the air conditioner that can regulate the temperature can be wider, resulting in higher temperature regulation efficiency.

[0034] For example, if the air conditioner is a vertical split-type air conditioner, the rotation axes of the two impellers 441 extend in the vertical direction. During operation, the two impellers 441 rotate along their respective rotation axes, driving air into the air conditioner through the rear air inlet 21 of the housing assembly 2. After the airflow passes through the heat exchange assembly and exchanges heat with the heat exchange assembly, the impellers 441 drive the airflow along the two air ducts 414 and finally out of the air conditioner through the corresponding air outlet 22.

[0035] Furthermore, the rotation axes of the two wind rotors 441 lie on a plane that is a first plane 83. The angle between the first plane 83 and the first reference plane 87 is greater than zero. The first reference plane 87 is a plane perpendicular to the fore-aft direction. By ensuring that the angle between the first plane 83 and the first reference plane 87 is greater than zero, the rotation axes of the two wind rotors 441 can be staggered in the fore-aft direction, thereby achieving relative balance in the air intake of the left and right air ducts 414 and reducing abnormal airflow noise in the air ducts 414. Furthermore, the spatial distance between the two wind rotors 441 in the left-right direction can be reduced, thereby correspondingly reducing the width of the fuselage in the left-right direction.

[0036] According to the air conditioner of the embodiment of the present invention, the air conditioner includes two wind wheels 441, and the plane where the rotation axes of the two wind wheels 441 are located is the first plane 83. The first reference plane 87 is a plane perpendicular to the front-to-back direction. By making the angle between the first plane 83 and the first reference plane 87 greater than zero, the rotation centers of the wind wheels 441 in the left and right air ducts 414 can be non-collinear in the width direction of the fuselage, which can improve the problem of unbalanced air intake of the left and right air ducts 414, and make the air intake of the left and right air ducts 414 relatively balanced, thereby reducing the abnormal sound in the air duct 414 and improving the user experience; and, since the rotation centers of the left and right wind wheels 441 are not collinear in the width direction of the fuselage, the width of the fuselage in the left and right directions can be reduced.

[0037] According to some embodiments of the present invention, referring to Figure 3 The angle α between the first plane 83 and the first reference plane 87 is 3° to 9°. For example, the angle α between the first plane 83 and the first reference plane 87 can be 3°, 4°, 5°, 6°, 7°, 8°, 9°, etc. By making the angle α between the first plane 83 and the first reference plane 87 not less than 3°, the degree of misalignment of the rotation axes of the left and right wind wheels 441 in the front-to-back direction can be sufficiently large, which can more fully compensate for the difference in the air intake volume on the left and right sides, make the air intake of the left and right air ducts 414 more relatively balanced, and better reduce the abnormal noise of the air duct 414. By making the angle α between the first plane 83 and the first reference plane 87 not greater than 9°, it can be avoided that the misalignment of the rotation axes of the left and right wind wheels 441 in the front-to-back direction is too large, which can avoid unbalanced air intake in the left and right air ducts 414.

[0038] According to some embodiments of the present invention, referring to Figure 3 and Figure 5 The rotation axis of the wind wheel 441 on the right side is the right rotation axis 81, and the rotation axis of the wind wheel 441 on the left side is the left rotation axis 82. The right rotation axis 81 is located to the right and front of the left rotation axis 82. Since the air inlet 21 of the air conditioner is asymmetrical in the left-right direction, the area of ​​the air inlet 21 to the right of the air conditioner's central axis is larger, and the area of ​​the air inlet 21 to the right of the air conditioner's central axis is also larger. By positioning the right rotation axis 81 to the right and front of the left rotation axis 82, the wind wheel 441 on the left side can be brought relatively closer to the air inlet 21, thereby compensating for the smaller air intake volume on the left side of the air conditioner than on the right side. This ensures that the air intake of the left and right air ducts 414 is relatively balanced, thereby better reducing the abnormal noise in the air duct 414.

[0039] According to some embodiments of the present invention, referring to Figure 3 and Figure 5The rotation axis of the impeller 441 on the right side is the right rotation axis 81, and the rotation axis of the impeller 441 on the left side is the left rotation axis 82. The housing includes a front panel 25. The distance between the right rotation axis 81 and the front panel 25 in the front-to-back direction is a first distance a, and the distance between the left rotation axis 82 and the front panel 25 in the front-to-back direction is a second distance b. The first distance a is less than the second distance b. Since the air inlet 21 of the air conditioner is asymmetrical in the left-to-right direction, the area of ​​the air inlet 21 to the right of the air conditioner's central axis is larger, and the area of ​​the air inlet 21 to the right of the air conditioner's central axis is larger. By making the first distance a smaller than the second distance b, that is, the right impeller 441 is positioned further forward and the left impeller 441 is positioned further back, the left impeller 441 can be brought relatively closer to the air inlet 21, thereby compensating for the smaller air intake volume on the left side of the air conditioner than on the right side. This ensures that the air intake of the left and right air ducts 414 is relatively balanced, thereby effectively reducing abnormal noise in the air duct 414.

[0040] According to some embodiments of the present invention, referring to Figure 4-Figure 5 The duct volute 41 includes a detachably connected front volute 411 and a duct baffle 413. The duct baffle 413 is connected to the front volute 411 and together defines two ducts 414. The duct baffle 413 is located between the two ducts 414. The heat exchanger assembly 3 is located between the duct assembly 4 and the air inlet 21 and includes a heat exchanger 32. The rear end surface of the duct baffle 413 is spaced apart from the heat exchanger 32 in the front-to-back direction. By spacing the rear end surface of the duct baffle 413 apart from the heat exchanger 32 in the front-to-back direction, interference between the rear end surface of the duct baffle 413 and the heat exchanger 32, which could cause damage to the duct baffle 413 or the heat exchanger 32, can be avoided. This also makes assembly of the duct baffle 413 easier.

[0041] According to some embodiments of the present invention, referring to Figure 3 The distance between the rear end face of the air duct baffle 413 and the heat exchanger 32 in the front-to-back direction is c, and the value range of c is 2mm to 7mm. For example, the value of the distance c between the rear end face of the air duct baffle 413 and the heat exchanger 32 in the front-to-back direction can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, etc. By ensuring that the distance c between the rear end face of the air duct baffle 413 and the heat exchanger 32 in the front-to-back direction is not less than 2mm, interference between the rear end face of the air duct baffle 413 and the heat exchanger 32 can be more effectively avoided; by ensuring that the distance c between the rear end face of the air duct baffle 413 and the heat exchanger 32 in the front-to-back direction is not greater than 7mm, it can be avoided that the gap is too large, causing the air flow between the left and right air ducts 414 to circulate through the gap and generate noise.

[0042] According to some embodiments of the present invention, referring to Figure 4The air duct volute 41 includes a detachably connected front volute 411 and an air duct partition 413. The air duct partition 413 is connected to the front volute 411 and together define two air ducts 414. The air duct partition 413 includes a detachably connected middle partition 4131 and a rear partition 4132. The middle partition 4131 is detachably connected to the front volute 411. The middle partition 4131 is connected between the rear partition 4132 and the front volute 411 and is located between the two air ducts 414 in the left-right direction. By making the air duct partition 413 comprise two parts, the middle partition 4131 and the rear partition 4132, which are detachable in the front-to-back direction, the manufacturing process of the air duct partition 413 can be simplified. By making the middle partition 4131 detachably connected to the front volute 411, the disassembly and installation process of the air conditioner can be simplified, making it easier to maintain or repair.

[0043] By making the air duct partition 413 comprise a middle partition 4131 and a rear partition 4132 that are detachable in the front-to-rear direction, the material of the middle partition 4131 can be changed independently. For example, the middle partition 4131 can be made of PP to reduce abnormal noise caused by thermal expansion and contraction of the middle partition 4131.

[0044] For example, the middle partition 4131 and the rear partition 4132 can be connected by a snap connection. By connecting the middle partition 4131 and the rear partition 4132 by a snap connection, the middle partition 4131 and the rear partition 4132 do not need to use fasteners, which can reduce the number of parts in the air conditioner, reduce assembly time, and improve assembly efficiency.

[0045] For example, the middle partition plate 4131 and the front volute 411 can be connected by a snap connection. By connecting the middle partition plate 4131 and the front volute 411 by a snap connection, the middle partition plate 4131 and the front volute 411 do not need to use fasteners, which can reduce the number of parts in the air conditioner, reduce assembly time, and improve assembly efficiency.

[0046] According to some embodiments of the present invention, referring to Figure 3The line connecting the projections of the rotation axes of the two wind wheels 441 on the second reference plane is the first line 84, the second reference plane is parallel to the horizontal plane, the first line 84 is a line segment and the midpoint of the first line 84 is the first midpoint 85, the plane passing through the first midpoint 85 and perpendicular to the left and right directions is the second plane 86, and the rear partition 4132 is located on the right side of the second plane 86. Since the air inlet 21 of the air conditioner is not symmetrical in the left-right direction, the area of ​​the air inlet 21 on the right side of the central axis of the air conditioner is larger, and the area of ​​the air inlet 21 on the right side of the central axis of the air conditioner is even larger. By making the rear partition 4132 on the right side of the second plane 86, that is, the area of ​​the right air duct 414 facing the air inlet 21 is smaller, and the area of ​​the left air duct 414 facing the air inlet 21 is larger, the air intake on the left side can be increased to compensate for the difference in the smaller air intake on the left side than on the right side caused by the left-right asymmetry of the air inlet 21 of the air conditioner, so that the air intake of the air ducts 414 on the left and right sides is relatively balanced, and the effect of reducing the abnormal noise of the air duct 414 is better.

[0047] According to some embodiments of the present invention, referring to Figure 3 The distance between the rear partition 4132 and the second plane 86 in the left-right direction is d, and the value range of d is 6mm to 18mm. For example, the value of d can be 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, etc. By making the value of the distance d between the rear partition 4132 and the second plane 86 in the left-right direction not less than 6mm, the offset of the rear partition 4132 in the left-right direction can be made large enough to fully compensate for the difference in the smaller air intake on the left side than on the right side caused by the left-right asymmetry of the air inlet 21 of the air conditioner; by making the value of the distance d between the rear partition 4132 and the second plane 86 in the left-right direction not more than 18mm, it can be avoided that the offset of the rear partition 4132 in the left-right direction is too large, resulting in the air intake on the left side being larger than that on the right side, and the air intake imbalance of the left and right air ducts 414 can be avoided.

[0048] According to some embodiments of the present invention, referring to Figure 5 The cross section of the rear partition 4132 is V-shaped or Y-shaped. By making the cross section of the rear partition 4132 Y-shaped or V-shaped, the rear partition 4132 and the middle partition 4131 can be connected at two points, making the connection between the rear partition 4132 and the middle partition 4131 more stable.
