[0054] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0055] The following refers to Figures 1 - 18 Describe an air conditioner according to an embodiment of the present utility model.

[0056] Refer to Figures 1 - 7 According to an embodiment of the present utility model, an air conditioner includes: a cabinet 1, a heat exchange and air supply assembly, and an air guiding assembly 3. The heat exchange and air supply assembly and the air guiding assembly 3 are arranged in the cabinet 1. An air inlet and at least one air outlet are formed on the cabinet 1. For example, one air outlet or multiple air outlets are formed on the cabinet 1.

[0057] The heat exchange and air supply assembly includes a fan component 22 and a heat exchanger component 21. The fan component 22 is used to drive the indoor air flow to enter the housing 1 through the air inlet and drive the air flow in the housing 1 to flow out through the air outlet and enter the room. The heat exchanger component 21 is used to exchange heat with the air flow in the housing 1 to achieve cooling or heating adjustment of the air flow.

[0058] The air guiding assembly 3 includes a mounting base 32 and a louver mechanism 31. The mounting base 32 is fixed to the housing 1. The louver mechanism 31 is an integrally formed part and includes a connecting rod 312 and a plurality of air guiding vanes 311. The connecting rod 312 extends along a first direction and is movable along the first direction. The plurality of air guiding vanes 311 are arranged along the first direction. The air guiding vane 311 has a fixed end and a free end which are oppositely arranged. The fixed end is connected to the connecting rod 312. The air guiding vane 311 includes a vane body 3113 and a first connecting portion 3115. The mounting base 32 is provided with a plurality of second connecting portions 322 connected to the first connecting portion 3115. The first connecting portion 3115 and the second connecting portion 322 are relatively movable. Among them, the distance between the first connecting portion 3115 and the fixed end is L1, and the range of L1 is 20 mm to 60 mm. Optionally, the distance between the first connecting portion 3115 and the fixed end is 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, etc.

[0059] The distances between the first connecting portion 3115 and the fixed end of the air guiding vanes 311 are different. In this way, during the operation of the louver assembly, the distance between the force application position of the second connecting portion 322 on the air guiding vane 311 and the fixed end is different, so that when the moving stroke of the connecting rod 312 along the first direction is certain, the angles at which the air guiding vanes 311 can swing during the force-induced swing are different. When the distance range between the first connecting portion 3115 and the fixed end of the plurality of air guiding vanes 311 is 20 mm to 60 mm, the swing angles of the plurality of air guiding vanes 311 are appropriate.

[0060] Optionally, the connecting rod 312 extends along the up-down direction and is movable along the up-down direction. The plurality of air guiding vanes 311 are arranged along the up-down direction, and the plurality of air guiding vanes 311 can swing in the up-down direction; optionally, the connecting rod 312 extends along the left-right direction and is movable along the left-right direction. The plurality of air guiding vanes 311 are arranged along the left-right direction, and the plurality of air guiding vanes 311 can swing in the left-right direction.

[0061] Optionally, the first connecting portion 3115 may be formed with a mounting hole 3116, and the second connecting portion 322 may be formed as a connecting shaft that passes through the mounting hole 3116 to connect the air guiding vane 311 to the mounting base 32; optionally, the first connecting portion 3115 may be formed as a connecting shaft, and the second connecting portion 322 may be formed as a mounting hole 3116, and the connecting shaft passes through the mounting hole 3116 to connect the air guiding vane 311 to the mounting base 32.

[0062] In the air conditioner according to an embodiment of the present invention, by making the range of the distance L1 between the first connecting portion 3115 and the fixed end of the air guiding vane 311 be 20 mm to 60 mm, during the process of the air guiding vane 311 swinging under force, the swinging angle of the air guiding vane 311 is relatively appropriate, so that the air outlet angle and the air outlet direction of the air flow in the air conditioner under the guiding action of the air guiding vane 311 are relatively appropriate, which is beneficial to improving the comfort of the air conditioner.

[0063] Optionally, the first direction is the up and down direction, and the plurality of air guiding vanes 311 are divided into multiple groups of air guiding vane groups arranged at intervals in the up and down direction, and the distances between the first connecting portions 3115 and the fixed ends of the air guiding vanes 311 in the multiple groups of air guiding vane groups are different. Optionally, the distances between the first connecting portions 3115 and the fixed ends of the air guiding vanes 311 in the same group of air guiding vanes 311 are the same.

[0064] Reference Figures 11 - 13 , according to some embodiments of the present invention, the blade body 3113 includes a thinning area 3118, the area of the blade body 3113 other than the thinning area 3118 is a non-thinning area 3119, the thickness of the thinning area 3118 is less than the thickness of the non-thinning area 3119, and the thinning area 3118 is more easily deformed than the non-thinning area 3119. The thinning area 3118 is located between the first connecting portion 3115 and the fixed end. During the process of the connecting rod 312 driving the blade body 3113 to move in the first direction, in the direction from the fixed end to the free end, the size of the thinning area 3118 is L2, and the range of L2 / L1 is 0.6 to 1. Optionally, L2 / L1 may be 0.6, 0.65, 0.7, 0.8, 0.83, 0.85, 0.9, 0.95 or 1, etc. By making the range of L2 / L1 be 0.6 to 1, when the blade body 3113 is in a stressed state, deformation is likely to occur between the first connecting portion 3115 and the fixed end, so that the blade body 3113 is easily swung.

[0065] Optionally, when the thinning area 3118 has a continuous structure in the direction from the fixed end to the free end, the size of the thinning area 3118 in the direction from the fixed end to the free end is L2; if the thinning area 3118 includes a plurality of sub-thinning areas 3118, and the plurality of sub-thinning areas 3118 are arranged at intervals in the direction from the fixed end to the free end, the size L2 of the thinning area 3118 is the sum of the sizes of the plurality of sub-thinning areas 3118 arranged at intervals.

[0066] Reference Figures 14 - 16 , according to some alternative embodiments of the present invention, the area on the blade body 3113 other than the thinning area 3118 is a non-thinning area 3119, the thickness of the thinning area 3118 is D1, the thickness of the non-thinning area 3119 is D2, and the range of D1 / D2 is 0.2 to 0.7. Optionally, D1 / D2 can be 0.2, 0.3, 0.35, 0.5, 0.55, 0.6 or 0.7, etc.

[0067] If the range of D1 / D2 is less than 0.2, the thickness of the thinning area 3118 is small, which may result in low strength of the thinning area 3118. In this way, during the operation of the louver mechanism 31, when the guiding vane 311 swings in the first direction, cracking or tearing is more likely to occur, and the service life of the louver mechanism 31 is short; if the range of D1 / D2 is greater than 0.7, the degree of thinning of the thinning area 3118 is small, which may make it still difficult for the thinning area 3118 to deform, and it is not easy for the first connecting portion 3115 of the guiding vane 311 and the fixed end to deform, further restricting the swing angle of the guiding vane 311, resulting in an unsatisfactory air guiding effect of the guiding vane 311. By making the range of D1 / D2 be 0.2 to 0.7, within this range, the thickness of the thinning area 3118 is appropriate, the thinning area 3118 is easy to deform and has good strength, so that the louver mechanism 31 can have a good air guiding effect and is also beneficial to improving the service life of the louver mechanism 31.

[0068] Reference Figures 14 - 16 , according to some alternative embodiments of the present invention, the area on the blade body 3113 other than the thinning area 3118 is a non-thinning area 3119, the thickness of the thinning area 3118 is D1, the range of D1 is 0.35 mm to 0.7 mm, the thickness of the non-thinning area 3119 is D2, and the range of D2 is 1 mm to 1.75 mm. Optionally, the thickness D1 of the thinning area 3118 can be 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.6 mm or 0.7 mm, etc. Optionally, the thickness D2 of the non-thinning area 3119 can be 1 mm, 1.05 mm, 1.1 mm, 1.2 mm, 1.25 mm, 1.3 mm, 1.5 mm, 1.6 mm, 1.65 mm or 1.75 mm, etc.

[0069] By making the range of D1 be 0.35 mm to 0.7 mm, the thinning area 3118 within this thickness range is prone to deformation and has good strength, so that the louver mechanism 31 can have a good air guiding effect and is also beneficial to improving the service life of the louver mechanism 31.

[0070] Optionally, taking the vertical plane perpendicular to the front-rear direction as the reference plane, the projection of the first connecting portion 3116 of the air guiding blade 311 in the reference plane is the first projection, and the range of the minimum distance between each first projection and the projection of the corresponding fixed end on the reference plane is 20 mm to 45 mm.

[0071] Reference Figures 11 - 16 , according to some optional embodiments of the present invention, during the upward movement of the connecting rod 312, the air guiding blade 311 can swing downward. The movement stroke of the connecting rod 312 in the up-down direction is certain. When the connecting rod 312 moves upward to the highest point, the air guiding blade 311 swings downward, and the position where the free end of the air guiding blade 311 is located is the lower limit position. The air guiding blade 311 can swing downward to the lower limit position. At the lower limit position, the angle between the air guiding blade 311 and the horizontal plane is the maximum air compression angle, and the range of the maximum air compression angle is 30° to 65°. Optionally, the maximum air compression angle can be 30°, 35°, 40°, 45°, 50° or 55°.

[0072] During the downward movement of the connecting rod 312, the air guiding blade 311 can swing upward. The movement stroke of the connecting rod 312 in the up-down direction is certain. When the connecting rod 312 moves downward to the lowest point, the air guiding blade 311 swings upward, and the position where the free end of the air guiding blade 311 is located is the upper limit position. The air guiding blade 311 can swing upward to the upper limit position. At the upper limit position, the angle between the air guiding blade 311 and the horizontal plane is the maximum air lifting angle, and the range of the maximum air lifting angle is 30° to 65°. Optionally, the maximum air lifting angle can be 30°, 35°, 40°, 45°, 50°, 55°, 60° or 65°.

[0073] If the maximum air compression angle or the maximum air lifting angle is less than 30°, during the operation of the louver assembly, the swinging range of the air guiding blade 311 is small, and the guiding effect on the upward or downward air flow is not obvious; if the maximum air compression angle or the maximum air lifting angle is greater than 65°, the angular relationship between the air guiding blade 311 and the air outlet is unreasonable, which may cause part of the air flow to flow towards the top plate or the bottom plate of the air conditioner, resulting in the inability of this part of the air flow to smoothly flow out of the air outlet into the room. By setting the range of the maximum air compression angle of the air guiding blade 311 to be 30° - 65°, and the range of the maximum air lifting angle to be 30° - 65°, during the operation of the louver assembly, the swinging angle ranges of the multiple air guiding blades 311 are appropriate, which can effectively guide the air flow in the air conditioner, so that the air flow can smoothly flow out of the air outlet into the room, and the air outlet angle of the air flow flowing out of the air outlet is appropriate, which is beneficial to improving the comfort of the air conditioner.

[0074] For example, the multiple air guiding blades 311 are divided into a first air guiding blade group, a second air guiding blade group, and a third air guiding blade group that are sequentially arranged at intervals in the up-down direction. The ranges of both the maximum air compression angle and the maximum air lifting angle of the first air guiding blade group are 55° - 65°, the ranges of both the maximum air compression angle and the maximum air lifting angle of the second air guiding blade group are 45° - 50°, and the ranges of both the maximum air compression angle and the maximum air lifting angle of the third air guiding blade group are 30° - 40°.

[0075] Reference Figures 1 - 16 , according to some alternative embodiments of the present utility model, an installation hole 3116 is formed on the first connection portion 3115, the second connection portion 322 is a connecting shaft, the connecting shaft passes through the installation hole 3116 and is movable relative to the installation hole 3116. The blade body 3113 has a first side and a second side that are oppositely arranged, and both the first side and the second side are located between the fixed end and the free end. Among them, the first side is closer to the installation base 32 than the second side, and the first connection portion 3115 is connected to the first side. By connecting the first connection portion 3115 of the air guiding blade 311 to the first side of the blade body 3113 that is close to the installation base 32, this setting facilitates the connecting shaft on the installation base 32 to pass through the installation hole 3116 formed on the first connection portion 3115. The setting of the first connection portion 3115 is also beneficial to enhancing the strength and stiffness of the air guiding blade 311, etc., so as to reduce or avoid damage such as cracks or tears at the installation hole 3116 of the air guiding blade 311 during the movement of the louver mechanism 31, which is beneficial to extending the service life of the air guiding blade 311; and under the stress state of the air guiding blade 311, the cooperation relationship between the first connection portion 3115 and the connecting shaft is more stable, and the connecting shaft is not easily disengaged from the installation hole 3116 of the first connection portion 3115, thereby being beneficial to further improving the connection stability between the installation base 32 and the air guiding blade 311.

[0076] Optionally, during the up-and-down swinging process of the air guiding vane 311, the connecting shaft can slide relative to the mounting hole 3116. For example, during the upward swinging process of the air guiding vane 311, the connecting shaft slides relative to the mounting hole 3116 in the direction from the free end to the fixed end.

[0089] Optionally, the multiple air guiding vanes 311 and the connecting rods 312 of the louver mechanism 31 are integrally formed, and the multiple air guiding vanes 311 are flexible vanes.

[0090] By making the air guiding vane 311 include the first sub - air guiding vane 3111 and the second sub - air guiding vane 3112, and making the connecting rod 312 located between the first sub - air guiding vane 3111 and the second sub - air guiding vane 3112 and connected to both the first sub - air guiding vane 3111 and the second sub - air guiding vane 3112, the first sub - air guiding vane 3111 and the second sub - air guiding vane 3112 are driven to move by the same connecting rod 312, which can reduce the number of connecting rods 312.
