[0059] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0060] Below, refer to Figures 1 - 22 Describe the air conditioner according to the embodiment of the present invention.

[0061] Refer to Figures 1 - 7 , for the air conditioner according to the embodiment of the present invention, the air conditioner includes: a housing 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 housing 1. An air inlet and at least one air outlet are formed on the housing 1. For example, one air outlet or multiple air outlets are formed on the housing 1.

[0062] 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 of 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 the refrigeration adjustment or heating adjustment of the air flow.

[0063] Refer to Figures 1 - 7, the air guiding assembly 3 includes a mounting base 32 and a louver mechanism 31 mounted on the mounting base 32. 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 in the first direction and is movable in the first direction. The plurality of air guiding vanes 311 are arranged in the first direction. A first connecting portion 3116 is provided on the air guiding vane 311, and a plurality of second connecting portions 322 connected to the first connecting portion 3116 are provided on the mounting base 32. The first connecting portion 3116 and the second connecting portion 322 are relatively movable.

[0064] The connection point between each air guiding vane 311 and the connecting rod 312 is a transmission connection point. The distance between the first connecting portion 3116 of the air guiding vane 311 and the corresponding transmission connection point is L. The distances L between the first connecting portions 3116 of at least two air guiding vanes 311 and the corresponding transmission connection points are different. Among them, the situation that the distances L between the first connecting portions 3116 of at least two air guiding vanes 311 and the corresponding transmission connection points are different can include the following several cases: For example, among the plurality of air guiding vanes 311, the distances L between the first connecting portions 3116 of two air guiding vanes 311 and the corresponding transmission connection points are different; For another example, the distances L between the first connecting portions 3116 of the plurality of air guiding vanes 311 and the corresponding transmission connection points can be divided into multiple types, and the multiple distances are different. Each distance corresponds to one or more air guiding vanes 311, and multiple types can be two or more; For another example, the distances L between the first connecting portions 3116 of the plurality of air guiding vanes 311 and the corresponding transmission connection points are all different.

[0065] The distance L between the first connecting portion 3116 of the air guiding vane 311 and the corresponding transmission connection point is different. In this way, during the working process 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 transmission connection point is different. When the movement stroke of the connecting rod 312 in the first direction is certain, the angles at which the air guiding vane 311 can swing during the force - induced swing are different. By making the distances between the first connecting portions 3116 of at least two air guiding vanes 311 and the corresponding transmission connection points different, some air guiding vanes 311 can swing at a small angle, while some swing at a large angle. The air guiding effects of the air guiding vanes 311 at different angles are different, so that different air flow patterns can be formed inside the air conditioner, and thus the air outlet direction and air outlet angle of the air flow at the air outlet can be adjusted, so that the air conditioner can blow out air in more different air outlet directions, air outlet angles, etc.

[0066] Optionally, the connecting rod 312 extends in the up-down direction and is movable in the up-down direction. A plurality of air guiding vanes 311 are arranged in 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 in the left-right direction and is movable in the left-right direction. A plurality of air guiding vanes 311 are arranged in the left-right direction, and the plurality of air guiding vanes 311 can swing in the left-right direction.

[0067] Optionally, the first connecting portion 3116 can be formed as a mounting hole, and the second connecting portion 322 can be formed as a connecting shaft. The connecting shaft passes through the mounting hole to connect the air guiding vane 311 to the mounting base 32; optionally, the first connecting portion 3116 can be formed as a connecting shaft, and the second connecting portion 322 can be formed as a mounting hole. The connecting shaft passes through the mounting hole to connect the air guiding vane 311 to the mounting base 32.

[0068] In the air conditioner according to the embodiment of the present invention, by making the distances between the first connecting portions 3116 of at least two air guiding vanes 311 and the corresponding transmission connection points different, during the operation of the louver assembly, the maximum angles at which at least two air guiding vanes 311 can swing are different, so that by making different air guiding vanes 311 swing at different angles, a plurality of air guiding vanes 311 can have multiple different air guiding effects on the air flow in the air conditioner. In this way, the air guiding effect of the louver assembly can be flexibly adjusted, and the louver assembly can form multiple different air flow patterns in the air conditioner. Under the action of the multiple different air guiding effects of the air guiding vanes 311, the air conditioner can have more air outlet modes, for example, it can realize air outlet in more different air outlet directions, air outlet angles, etc., so as to better meet the user's usage requirements.

[0069] Reference Figures 8 - 16 , according to some embodiments of the present invention, the first direction is the up-down direction. A plurality of air guiding vanes 311 are divided into multiple groups of air guiding vane groups arranged at intervals in the up-down direction. Each group of air guiding vane groups includes at least one air guiding vane 311. For example, each group of air guiding vanes 311 includes one or more air guiding vanes 311. The distance L between the first connecting portion 3116 of the air guiding vane 311 of the lower air guiding vane group in two adjacent air guiding vane groups and the corresponding transmission connection point is greater than the distance L between the first connecting portion 3116 of the air guiding vane 311 of the upper air guiding vane group in two adjacent air guiding vane groups and the corresponding transmission connection point.

[0070] For example, the multiple air guiding vanes 311 are divided into three groups of air guiding vane groups arranged at intervals in the up-down direction. Each group of air guiding vanes 311 includes at least one air guiding vane 311. The three groups of air guiding vane groups are respectively the first air guiding vane group, the second air guiding vane group, and the third air guiding vane group from top to bottom. The distance L between the first connecting portion 3116 of the air guiding vane 311 of the third air guiding vane group and the corresponding transmission connection point is greater than the distance L between the first connecting portion 3116 of the air guiding vane 311 of the second air guiding vane group and the corresponding transmission connection point. The distance L between the first connecting portion 3116 of the air guiding vane 311 of the second air guiding vane group and the corresponding transmission connection point is greater than the distance L between the first connecting portion 3116 of the air guiding vane 311 of the first air guiding vane group and the corresponding transmission connection point.

[0071] By making the distance L between the first connecting portion 3116 of the air guiding vane 311 of the air guiding vane group located below in two adjacent air guiding vane groups and the corresponding transmission connection point greater than the distance L between the first connecting portion 3116 of the air guiding vane 311 of the air guiding vane group located above in two adjacent air guiding vane groups and the corresponding transmission connection point, when the movement stroke of the connecting rod 312 in the first direction is certain, the angles by which the air guiding vanes 311 of two adjacent air guiding vane groups can swing during the forced swing are different. The swing angle of the air guiding vane 311 of the air guiding vane group located below in two adjacent air guiding vane groups is smaller than the swing angle of the air guiding vane 311 of the air guiding vane group located below in two adjacent air guiding vane groups. In this way, the smaller the swing angle of the air guiding vane 311 of the air guiding vane group located lower, the more conducive to increasing the air supply distance of the lower air guiding vane 311, and the larger the swing angle of the air guiding vane 311 of the air guiding vane group located higher, the more conducive to increasing the angle of the upper air guiding vane 311 pressing the air downward or lifting the air upward, so as to be more conducive to better lifting the cold air of the air conditioner or better pressing down the hot air of the air conditioner, all of which are conducive to improving the comfort of the air conditioner.

[0072] For example, in the cooling mode of the air conditioner, by making the distance L between the first connecting portion 3116 of the air guiding blade 311 of the lower air guiding blade group among two adjacent air guiding blade groups and the corresponding transmission connection point greater than the distance L between the first connecting portion 3116 of the air guiding blade 311 of the upper air guiding blade group among two adjacent air guiding blade groups and the corresponding transmission connection point, the connecting rod 312 moves downward, the air guiding blade 311 swings upward, the upward swing angle of the air guiding blade 311 of the upper air guiding blade group is larger, which is beneficial to lifting more cold air upward, so that more cold air flows out towards the indoor ceiling; the upward swing angle of the air guiding blade 311 of the lower air guiding blade group is smaller, which is beneficial to increasing the air supply distance of these air guiding blades 311 and facilitating long-distance air supply of the air conditioner; all of these are beneficial to improving the cooling comfort of the air conditioner.

[0073] For example, in the heating mode of the air conditioner, by making the distance L between the first connecting portion 3116 of the air guiding blade 311 of the lower air guiding blade group among two adjacent air guiding blade groups and the corresponding transmission connection point greater than the distance L between the first connecting portion 3116 of the air guiding blade 311 of the upper air guiding blade group among two adjacent air guiding blade groups and the corresponding transmission connection point, the connecting rod 312 moves upward, the air guiding blade 311 swings downward, the downward swing angle of the air guiding blade 311 of the upper air guiding blade group is larger, which is beneficial to pressing more hot air downward, so that more hot air flows out towards the indoor ground or through the lower part of the air outlet; the downward swing angle of the air guiding blade 311 of the lower air guiding blade group is smaller, which is beneficial to increasing the air supply distance of these air guiding blades 311 and facilitating long-distance air supply of the air conditioner, and in this way, some of the hot air pressed down by the upper air guiding blade 311 can also be sent to a farther ground in the room; all of these are beneficial to improving the heating comfort of the air conditioner.

[0074] Reference Figures 8 - 16 , according to some alternative embodiments of the present invention, at least one set of air guiding blade groups includes a plurality of air guiding blades 311 arranged in the up-down direction, and the distances between the first connecting portions 3116 of the plurality of air guiding blades 311 in the same air guiding blade group and the corresponding transmission connection points are the same.

[0075] Among them, at least one set of air guiding blade groups includes a plurality of air guiding blades 311 arranged in the up-down direction, and the following situations may be included: for example, one set of air guiding blade groups among multiple sets of air guiding blade groups includes a plurality of air guiding blades 311 arranged in the up-down direction; for another example, several sets of air guiding blade groups among multiple sets of air guiding blade groups include a plurality of air guiding blades 311 arranged in the up-down direction; for yet another example, all of the multiple sets of air guiding blade groups include a plurality of air guiding blades 311 arranged in the up-down direction.

[0076] For example, the multiple air guiding vanes 311 are divided into three groups of air guiding vane groups arranged at intervals in the up-down direction. Each group of air guiding vanes 311 includes multiple air guiding vanes 311. The three groups of air guiding vane groups are, from top to bottom, the first air guiding vane group, the second air guiding vane group, and the third air guiding vane group. The distance L between the first connecting portion 3116 of the air guiding vane 311 in the third air guiding vane group and the corresponding transmission connection point is greater than the distance L between the first connecting portion 3116 of the air guiding vane 311 in the second air guiding vane group and the corresponding transmission connection point. The distance L between the first connecting portion 3116 of the air guiding vane 311 in the second air guiding vane group and the corresponding transmission connection point is greater than the distance L between the first connecting portion 3116 of the air guiding vane 311 in the first air guiding vane group and the corresponding transmission connection point.

[0077] By making the distances between the first connecting portions 3116 of the multiple air guiding vanes 311 in the same air guiding vane group and the corresponding transmission connection points the same, the swinging angles of the air guiding vanes 311 in the same group are approximately the same or the same. The air guiding vanes 311 in the same group can make the local airflow sent out by the air conditioner evenly distributed, which is beneficial to further improving the comfort of the air conditioner; and such a setting makes it impossible for the air guiding vanes 311 in the same group to interfere with each other during the rotation process, and the uniform interval between adjacent two air guiding vanes 311 enables the airflow to flow smoothly, which is also beneficial to reducing noise; in addition, such a setting is also beneficial to reducing the forming difficulty of the air guiding component 3.

[0078] Reference Figures 8 - 16 Referring to

[0079] Among them, at least one group of air guiding vane groups includes multiple air guiding vanes 311 arranged in the up-down direction, and the following situations may be included: for example, one group of air guiding vane groups among multiple groups of air guiding vane groups includes multiple air guiding vanes 311 arranged in the up-down direction; for another example, several groups of air guiding vane groups among multiple groups of air guiding vane groups include multiple air guiding vanes 311 arranged in the up-down direction; for still another example, all multiple groups of air guiding vane groups include multiple air guiding vanes 311 arranged in the up-down direction.

[0080] For example, the multiple air guiding vanes 311 are divided into three groups of air guiding vane groups arranged at intervals in the up-down direction. Each group of air guiding vanes 311 includes multiple air guiding vanes 311. The three groups of air guiding vane groups are, from top to bottom, the first air guiding vane group, the second air guiding vane group, and the third air guiding vane group. The distance between the first connecting portion 3116 of the lower air guiding vane 311 and the corresponding transmission connection point among two adjacent air guiding vanes 311 in the same air guiding vane group is greater than the distance between the first connecting portion 3116 of the upper air guiding vane 311 and the corresponding transmission connection point among two adjacent air guiding vanes 311 in the same air guiding vane group. Moreover, the distance L between the first connecting portion 3116 of any air guiding vane 311 in the third air guiding vane group and the corresponding transmission connection point is greater than the distance L between the first connecting portion 3116 of any air guiding vane 311 in the second air guiding vane group and the corresponding transmission connection point. The distance L between the first connecting portion 3116 of any air guiding vane 311 in the second air guiding vane group and the corresponding transmission connection point is greater than the distance L between the first connecting portion 3116 of any air guiding vane 311 in the first air guiding vane group and the corresponding transmission connection point.

[0081] By making the distance between the first connecting portion 3116 of the lower air guiding vane 311 and the corresponding transmission connection point among two adjacent air guiding vanes 311 in the same air guiding vane group greater than the distance between the first connecting portion 3116 of the upper air guiding vane 311 and the corresponding transmission connection point among two adjacent air guiding vanes 311 in the same air guiding vane group, in the direction from bottom to top, the distance between the first connecting portion 3116 of the multiple air guiding vanes 311 and the corresponding transmission connection point gradually decreases, so that the swing angles of the multiple air guiding vanes 311 gradually increase in the direction from bottom to top. In this way, the air guiding vanes 311 located more in the upper part can more easily achieve a larger downward or upward air pressing angle, which is conducive to gradually lifting the cold air in the air conditioner upward or gradually pressing the hot air of the air conditioner downward, thus being conducive to improving the comfort of the air conditioner; while the air guiding vanes 311 located in the lower part can send the air flow in the air conditioner over a long distance, which is conducive to increasing the air supply distance of the air conditioner to improve the comfort of the air conditioner.

[0082] Reference Figures 8 - 16, according to some alternative embodiments of the present utility model, the difference range between the distance from the first connecting portion 3116 of the air guiding blade 311 of two adjacent air guiding blade groups to the corresponding transmission connection point is 2 mm to 10 mm. If the difference range between the distance from the first connecting portion 3116 of the air guiding blade 311 of two adjacent air guiding blade groups to the corresponding transmission connection point is less than 2 mm, the swing angles of the air guiding blades 311 of two adjacent air guiding blade groups have a small difference, and the air guiding effects of the air guiding blades 311 of two adjacent air guiding blade groups have a small difference, resulting in limited adjustment effects on the air outlet direction, air outlet angle, etc. of the air outlet. If the distance between the first connecting portion 3116 of the air guiding blade 311 of two adjacent air guiding blade groups and the corresponding transmission connection point is greater than 10 mm, the swing angle of the air guiding blade 311 of the air guiding blade group located above will be larger, and the angle between these air guiding blades 311 and the connecting rod 312 will be smaller, which is not conducive to the smooth flow of air, and the air pressing angle or air lifting angle of the air guiding blade 311 is too large, which is not conducive to the air flowing out of the air outlet.

[0083] By making the difference range between the distance from the first connecting portion 3116 of the air guiding blade 311 of two adjacent air guiding blade groups to the corresponding transmission connection point be 2 mm to 10 mm, the swing angles of the air guiding blades 311 of each air guiding blade group are appropriate, which is conducive to the smooth flow of air in the air conditioner and the smooth outflow of air through the air outlet, and can also effectively adjust the air outlet direction, air outlet angle, etc. of the air outlet of the air conditioner, so that the user can select a suitable air supply mode according to actual needs, which is conducive to improving the comfort of the air conditioner.

[0084] Reference Figures 17 - 20 , according to some alternative embodiments of the present utility model, the air guiding blade 311 has a fixed end and a free end which are oppositely arranged, and the fixed end is connected to the connecting rod 312.

[0085] 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 and 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 swings downward to the lower limit position. At the lower limit position, the air guiding blade 311 extends obliquely downward along the direction from the fixed end to the free end, and the angle between the air guiding blade 311 and the horizontal plane is the maximum air pressing angle. The maximum air pressing angle of the air guiding blade group located below in two adjacent air guiding blade groups is smaller than the maximum air pressing angle of the air guiding blade group located above in two adjacent air guiding blade groups.

[0086] 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 and down direction is fixed. 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 swings upward to the upper limit position. At the upper limit position, the air guiding blade 311 extends obliquely upward in the direction from the fixed end to the free end. The angle between the air guiding blade 311 and the horizontal plane is the maximum air-lifting angle. The maximum air-lifting angle of the air guiding blade group located below in two adjacent air guiding blade groups is smaller than the maximum air-lifting angle of the air guiding blade group located above in two adjacent air guiding blade groups.

[0087] For example, a plurality of air guiding blades 311 are divided into three groups of air guiding blades arranged at intervals in the up and down direction. Each group of air guiding blades 311 includes a plurality of air guiding blades 311. The three groups of air guiding blades are the first air guiding blade group, the second air guiding blade group, and the third air guiding blade group from top to bottom. During the upward movement of the connecting rod 312, the air guiding blade 311 can swing downward. The air guiding blade 311 swings downward to the lower limit position. At the lower limit position, the maximum air-pressing angle of the air guiding blades 311 in the first air guiding blade group is greater than the maximum air-pressing angle of the air guiding blades 311 in the second air guiding blade group, and the maximum air-pressing angle of the air guiding blades 311 in the second air guiding blade group is greater than the maximum air-pressing angle of the air guiding blades 311 in the third air guiding blade group. During the downward movement of the connecting rod 312, the air guiding blade 311 can swing upward. The air guiding blade 311 swings upward to the upper limit position. At the upper limit position, the maximum air-lifting angle of the air guiding blades 311 in the first air guiding blade group is greater than the maximum air-lifting angle of the air guiding blades 311 in the second air guiding blade group, and the maximum air-lifting angle of the air guiding blades 311 in the second air guiding blade group is greater than the maximum air-lifting angle of the air guiding blades 311 in the third air guiding blade group.

[0088] By making the maximum air-pressing angle of the air guiding blade group located below in two adjacent air guiding blade groups smaller than the maximum air-pressing angle of the air guiding blade group located above in two adjacent air guiding blade groups at the lower limit position of the air guiding blade 311, the swinging angle of the air guiding blades 311 in the air guiding blade group located lower is smaller, which is beneficial to increasing the air supply distance of the lower air guiding blades 311. For example, the hot air can be sent to a farther place in the room from the air conditioner. And the swinging angle of the air guiding blades 311 in the air guiding blade group located higher is larger, and the larger air-pressing angle is beneficial to pressing down the hot air of the air conditioner better, so that more hot air in the air conditioner can enter the room through the lower part of the air outlet and flow towards the ground in the room, which is beneficial to improving the heating comfort of the air conditioner.

[0089] By making the maximum wind-lifting angle of the lower air guide vane group in two adjacent air guide vane groups smaller than that of the upper air guide vane group when the air guide vane 311 is at its upper limit position, the swing angle of the air guide vane 311 in the lower air guide vane group is smaller, which is beneficial to increasing the air supply distance of the lower air guide vane 311. For example, cold air can be sent to a farther place in the room from the air conditioner. And the swing angle of the air guide vane 311 in the upper air guide vane group is larger, and the larger wind-lifting is beneficial to better downward lifting of the cold air of the air conditioner, so that more cold air in the air conditioner can flow out through the air outlet upward into the room and flow towards the ceiling of the room, which is beneficial to improving the refrigeration comfort of the air conditioner.

[0090] Reference Figures 17 - 20 , according to some optional embodiments of the present invention, the difference range of the maximum air-pressing angles of two adjacent air guide vane groups is 10° to 15°. If the difference range of the maximum air-pressing angles of two adjacent air guide vane groups is less than 10°, the difference in the downward pressing angles of the air guide vanes 311 in two adjacent air guide vane groups is small, and the difference in the air guiding effects of the air guide vanes 311 in two adjacent air guide vane groups is small, resulting in limited adjustment effects on the air outlet direction, air outlet angle, etc. If the difference range of the maximum air-pressing angles of two adjacent air guide vane groups is greater than 15°, it is not conducive to the smooth flow of air, and the too large air-pressing angle of the air guide vane 311 is not conducive to the air flowing out through the air outlet, resulting in poor comfort of air conditioning. By making the difference range of the maximum air-pressing angles of two adjacent air guide vane groups be 10° to 15°, the maximum air-pressing angles of each air guide vane group are different but the swing angles are appropriate. In this way, during the operation of the louver assembly, multiple air guide vanes 311 can effectively guide the air flow in the air conditioner, so that the air flow can smoothly flow out through the air outlet into the room, and the air outlet angle of the air flow flowing out through the air outlet is appropriate, which is beneficial to improving the comfort of the air conditioner.

[0091] For example, multiple air guide vanes 311 are divided into three groups of air guide vanes arranged at intervals in the up-down direction. Each group of air guide vanes 311 includes multiple air guide vanes 311. The three groups of air guide vanes are the first air guide vane group, the second air guide vane group and the third air guide vane group from top to bottom. The maximum air-pressing angle of the first air guide vane group is greater than that of the second air guide vane group, and the difference range of the maximum air-pressing angles of the first air guide vane group and the second air guide vane group is 10° to 15°; the maximum air-pressing angle of the second air guide vane group is greater than that of the third air guide vane group, and the difference range of the maximum air-pressing angles of the second air guide vane group and the third air guide vane group is 10° to 15°.

[0092] Reference Figures 17 - 20, according to some alternative embodiments of the present utility model, the difference range of the maximum wind-lifting angles of two adjacent air guiding vane groups is 10° to 15°. If the difference range of the maximum wind-lifting angles of two adjacent air guiding vane groups is less than 10°, the difference in the upward angles of the air guiding vanes 311 of two adjacent air guiding vane groups is small, and the difference in the air guiding effects of the air guiding vanes 311 of two adjacent air guiding vane groups is small, resulting in limited adjustment effects on the air outlet direction, air outlet angle, etc. If the difference range of the maximum wind-pressing angles of two adjacent air guiding vane groups is greater than 15°, it is not conducive to the smooth flow of air, and the too large wind-pressing angle of the air guiding vane 311 is not conducive to the air flowing out through the air outlet, resulting in poor comfort of air conditioning. By making the difference range of the maximum wind-lifting angles of two adjacent air guiding vane groups be 10° to 15°, the maximum wind-lifting angles of each air guiding vane group are different but the swing angles are appropriate. In this way, during the operation of the louver assembly, multiple air guiding vanes 311 can effectively guide the air flow in the air conditioner, so that the air flow can smoothly flow out through the air outlet into the room, and the air outlet angle of the air flow flowing out through the air outlet is appropriate, which is beneficial to improving the comfort of the air conditioner.

[0093] For example, multiple air guiding vanes 311 are divided into three groups of air guiding vane groups arranged at intervals in the up-down direction. Each group of air guiding vanes 311 includes multiple air guiding vanes 311. The three groups of air guiding vane groups are the first air guiding vane group, the second air guiding vane group, and the third air guiding vane group from top to bottom. The maximum wind-lifting angle of the first air guiding vane group is greater than the maximum wind-lifting angle of the second air guiding vane group, and the difference range of the maximum wind-lifting angles of the first air guiding vane group and the second air guiding vane group is 10° to 15°; the maximum wind-lifting angle of the second air guiding vane group is greater than the maximum wind-lifting angle of the third air guiding vane group, and the difference range of the maximum wind-lifting angles of the second air guiding vane group and the third air guiding vane group is 10° to 15°.

[0094] Reference Figures 17 - 20, according to some alternative embodiments of the present utility model, the plurality of air guiding vanes 311 are divided into a first air guiding vane group, a second air guiding vane group, and a third air guiding vane group that are arranged at intervals in sequence along the direction from top to bottom. The maximum air pressing angle of the first air guiding vane group is α1, and the maximum air lifting angle is β1. The ranges of both the maximum air pressing angle α1 and the maximum air lifting angle β1 are 55° - 65°. The maximum air pressing angle of the second air guiding vane group is α2, and the maximum air lifting angle is β2. The ranges of both the maximum air pressing angle α2 and the maximum air lifting angle β2 are 45° - 50°. The maximum air pressing angle of the third air guiding vane group is α3, and the maximum air lifting angle is β3. The ranges of both the maximum air pressing angle α3 and the maximum air lifting angle β3 are 30° - 40°. Such a setting makes the air pressing angles and air lifting angles of the first air guiding vane group, the second air guiding vane group, and the third air guiding vane group appropriate during the operation of the air guiding vanes 311. Moreover, the first air guiding vane group can effectively press down or effectively lift a part of the air flow inside the air conditioner. The third air guiding vane group can send a part of the air flow inside the air conditioner to a long distance through the air outlet. The second air guiding vane group can make a part of the air flow inside the air conditioner flow out to the room through the air outlet at this air outlet angle. The three air guiding vane groups cooperate with each other, enabling the louver mechanism 31 to have a good air guiding effect.

[0095] Reference Figures 8 - 20 , according to some alternative embodiments of the present utility model, the distance between two adjacent air guiding vane groups is d1, and the distance between two adjacent air guiding vanes 311 in the same air guiding vane group is d2, and d1 is greater than d2.

[0096] By making the distance d1 between two adjacent air guiding vane groups greater than the distance d2 between two adjacent air guiding vanes 311 in the same air guiding vane group, a larger installation space 5 is formed between two adjacent air guiding vane groups, which is convenient for arranging other components of the air conditioner and avoiding interference between the air guiding vanes 311 and other components of the air conditioner during the up-and-down swinging process. Additionally, by making d1 greater than d2, this helps to effectively utilize aerodynamics and can adjust the wind speed of the air flow, etc. in different air guiding vane groups. For example, making d1 greater than d2 makes the wind speed between two adjacent air guiding vanes 311 in the same air guiding vane group greater than the wind speed between two adjacent air guiding vane groups, thereby realizing the adjustment of the wind speed of the air flow flowing out through the air outlet, which is beneficial to improving the comfort of the air conditioner.

[0097] Reference Figures 8 - 20, according to some alternative embodiments of the present utility model, the distance between two adjacent air guiding vanes 311 in the lower air guiding vane group among two adjacent air guiding vane groups is greater than the distance between two adjacent air guiding vanes 311 in the upper air guiding vane group among two adjacent air guiding vane groups. By making the distance between two adjacent air guiding vanes 311 in the lower air guiding vane group among two adjacent air guiding vane groups greater than the distance between two adjacent air guiding vanes 311 in the upper air guiding vane group among two adjacent air guiding vane groups, the arrangement of the air guiding vanes 311 in the upper air guiding vane group is denser, which is beneficial to optimizing the air guiding effect of this air guiding vane group. For example, in the cooling mode of the air conditioner, the upper air guiding vane group can press more cold air downward, facilitating more cold air to flow out towards the indoor ground.

[0098] Reference Figures 8 - 20 , according to some alternative embodiments of the present utility model, the difference between the distance between two adjacent air guiding vanes 311 in the lower air guiding vane group among two adjacent air guiding vane groups and the distance between two adjacent air guiding vanes 311 in the upper air guiding vane group among two adjacent air guiding vane groups is greater than or equal to 5 mm. By making the difference between the distance between two adjacent air guiding vanes 311 in the lower air guiding vane group among two adjacent air guiding vane groups and the distance between two adjacent air guiding vanes 311 in the upper air guiding vane group among two adjacent air guiding vane groups greater than or equal to 5 mm, if the difference in this distance is less than 5 mm, the difference in the air guiding effect between the two adjacent air guiding vane groups is not obvious, and the improvement effect on the air guiding effect of the upper air guiding vane group is not obvious.

[0099] Reference Figures 1 - 7 , according to some embodiments of the present utility model, the first connecting portion 3116 is a mounting hole, the second connecting portion 322 is a connecting shaft, and the connecting shaft passes through the mounting hole and is movable relative to the mounting hole. By making the first connecting portion 3116 a mounting hole and the second connecting portion 322 a connecting shaft, the stiffness of the mounting substrate is usually higher than that of the air guiding vane 311, so the stiffness of the connecting shaft is higher, which is beneficial to improving the stability and reliability of the connection relationship between the mounting base 32 and the air guiding vane 311. In this way, under the driving action of the connecting rod 312, the air guiding vane 311 can swing stably to adjust the air flow direction inside the air conditioner, thus being beneficial to the stable operation of the louver mechanism 31.

[0100] Reference Figures 1 - 20, according to some alternative embodiments of the present utility model, the air guiding vane 311 includes a vane body 3113 and a mounting block 3115. The air guiding vane 311 has a fixed end and a free end which are oppositely arranged, and the fixed end is connected to the connecting rod 312. The vane body 3113 has a first side and a second side which 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 mounting base 32 than the second side. The mounting block 3115 is connected to the first side, and a mounting hole is formed on the mounting block 3115. By making the air guiding vane 311 include the vane body 3113 and the mounting block 3115, and connecting the mounting block 3115 to the first side of the vane body 3113 close to the mounting base 32, such a setting facilitates the connecting shaft on the mounting base 32 to pass through the mounting hole formed on the mounting block 3115. The setting of the mounting block 3115 is also beneficial to enhancing the strength and rigidity of the air guiding vane 311, etc., so as to reduce or avoid damage situations such as cracks or tears at the mounting hole of the air guiding vane 311 during the movement of the louver mechanism 31, which is beneficial to extending the service life of the air guiding vane 311; and under the stress state of the air guiding vane 311, the matching relationship between the mounting block 3115 and the connecting shaft is more stable, and the connecting shaft is not easily disengaged from the mounting hole of the mounting block 3115, thereby being beneficial to further improving the connection stability between the mounting base 32 and the air guiding vane 311.

[0101] Optionally, during the swinging of the air guiding vane 311 in the up and down direction, the connecting shaft can slide relative to the mounting hole 3116. For example, during the upward swinging 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.

[0102] Reference Figures 1 - 13 , according to some alternative embodiments of the present utility model, the central axis of the mounting hole extends in the direction from the first side to the second side. By making the central axis of the mounting hole extend in the direction from the first side to the second side, and the mounting base 32 is close to the first side, such a setting enables the staff to easily align the mounting hole of the air guiding vane 311 with the connecting shaft on the mounting base 32 during the installation and production of the air conditioner, thereby being beneficial to improving the assembly efficiency.

[0103] Reference Figures 1 - 13, according to some alternative embodiments of the present utility model, an installation notch 3114 is formed on the first side edge, and the installation block 3115 is installed in the installation notch 3114 and connected to the inner wall of the installation notch 3114. By forming the installation notch 3114 on the first side edge and installing the installation block 3115 at the installation notch 3114, the installation notch 3114 can avoid the connecting shaft passing through the installation hole, preventing interference between the connecting shaft and the blade body 3113. Additionally, by installing the installation block 3115 in the installation notch 3114, during the upward or downward swing of the air guiding blade 311, the acting force received by the air guiding blade 311 from the connecting shaft causes the swing angle range in the up and down directions to be relatively close and uniform, making the air guiding effects of the air guiding blade 311 in the upward and downward directions more uniform, which is beneficial to improving the comfort of the air conditioner.

[0104] Reference Figure 6 , according to some alternative embodiments of the present utility model, a first limiting protrusion 3221 and a second limiting protrusion 3222 are formed on the outer peripheral wall of the second connecting portion 322 at intervals along the axial direction of the second connecting portion 322, and the installation block 3115 is located between the first limiting protrusion 3221 and the second limiting protrusion 3222 along the axial direction of the connecting shaft. By forming the first limiting protrusion 3221 and the second limiting protrusion 3222 on the outer peripheral wall of the second connecting portion 322 at intervals along the axial direction of the second connecting portion 322, the first limiting protrusion 3221 and the second limiting protrusion 3222 form a limiting effect on the installation block 3115 in the axial direction to enhance the connection stability between the second connecting portion 322 and the installation block 3115.

[0105] Reference Figures 1 - 4 , according to some alternative embodiments of the present utility model, an air outlet frame 11 is provided inside the housing 1. The air outlet frame 11 is located on the downstream side of the heat exchange and air supply assembly and defines an air outlet passage with the installation base 32. The air outlet frame 11 can guide the air flow flowing through the heat exchange and air supply assembly inside the air conditioner towards the direction of the air outlet passage, and the louver mechanism 31 is installed on the side of the installation base 32 facing the air outlet passage. The air outlet frame 11 can guide the air flow flowing through the heat exchange and air supply assembly inside the air conditioner towards the direction of the air outlet passage, so that the air flow flows out of the air conditioner through the air outlet after flowing through the air outlet passage. By installing the louver mechanism 31 on the side of the installation base 32 facing the air outlet passage, it is convenient for the louver mechanism 31 to effectively adjust the air flow direction in the air flow passage through movement, thereby realizing the effective adjustment of the air outlet direction of the air outlet by the louver mechanism 31.

[0106] Reference Figures 1 - 11, Optionally, the air conditioner further includes a louver driving device 4 disposed in an installation space 5 defined between the air guiding assembly 3 and the housing 1. A first guiding hole 321 is formed on the installation base 32. The louver driving device 4 includes a louver driving mechanism 41 and a transmission arm 42. The louver driving mechanism 41 is installed on the installation base 32. The transmission arm 42 passes through the first guiding hole 321 and is connected to the connecting rod 312 to drive the louver mechanism 31 to move.

[0107] Reference Figures 21 - 22 , The louver driving mechanism 41 includes a driving motor 411 and a gear-rack transmission mechanism. The gear-rack transmission mechanism includes a transmission gear 412 and a transmission rack 413 that mesh with each other. The transmission rack 413 extends in the up-down direction and is movable in the up-down direction. The transmission gear 412 is connected to the motor shaft of the driving motor 411. The transmission arm 42 is connected to the transmission rack 413. The louver driving device 4 further includes a driving housing 43. The louver driving mechanism 41 is disposed in the driving housing 43. A chute 432 extending in the up-down direction is provided in the driving housing 43. A slider is provided on the transmission rack 413, and the slider is slidably received in the chute 432 in the up-down direction.

[0108] Reference Figures 1 - 4 , According to some optional embodiments of the present invention, the first direction is the up-down direction. The air outlet includes a first air outlet 12 and a second air outlet 13 arranged at intervals in the left-right direction. The air outlet passage includes a first air outlet passage 14 and a second air outlet passage 15 arranged left and right. The first air outlet passage 14 corresponds to and communicates with the first air outlet 12, and the second air outlet passage 15 corresponds to and communicates with the second air outlet 13.

[0109] Each louver blade 311 includes a first sub-louver blade 3111 and a second sub-louver blade 3112 arranged left and right. First connection portions 3116 are provided on both the first sub-louver blade 3111 and the second sub-louver blade 3112. The first sub-louver blade 3111 is located in the first air outlet passage 14, and the second sub-louver blade 3112 is located in the second air outlet passage 15. The connecting rod 312 is located between the first sub-louver blade 3111 and the second sub-louver blade 3112 and is connected to both the first sub-louver blade 3111 and the second sub-louver blade 3112.

[0110] The plurality of second connection portions 322 are divided into two groups of second connection portion groups arranged at intervals in the left-right direction. Each group of second connection portion groups includes a plurality of second connection portions 322 arranged at intervals up and down. The second connection portions 322 of the two groups of second connection portion groups are respectively connected to the first sub-louver blade 3111 and the second sub-louver blade 3112.

[0111] By making the air guide vane 311 include a first sub-air guide vane 3111 and a second sub-air guide vane 3112, and arranging the connecting rod 312 between the first sub-air guide vane 3111 and the second sub-air guide vane 3112 and connecting it to both the first sub-air guide vane 3111 and the second sub-air guide vane 3112, the first sub-air guide vane 3111 and the second sub-air guide vane 3112 are driven to move by the same connecting rod 312, which can reduce the number of connecting rods 312. All of these can reduce the number of components of the air conditioner, simplify the structure, thereby reducing the installation steps and the required time, which is beneficial to reducing the production cost of the air conditioner and improving the production efficiency of the air conditioner. In addition, reducing the number of connecting rods 312 can also correspondingly reduce the number of driving devices for driving the connecting rods 312.

[0112] For example, in the heating mode of the air conditioner, the louver driving device 4 drives the connecting rod 312 to move upward, and the connecting rod 312 drives the plurality of air guide vanes 311 to move and swing the plurality of air guide vanes 311 downward. The first sub-air guide vane 3111 guides the air flow in the first air outlet channel 14 downward, and the second sub-air guide vane 3112 guides the air flow in the second air outlet channel 15 downward, so that the air flow flows downward in the room through the first air outlet 12 and the second air outlet 13 to perform heating adjustment on the room.

[0113] For example, in the cooling mode of the air conditioner, the louver driving device 4 drives the connecting rod 312 to move downward, and the connecting rod 312 drives the plurality of air guide vanes 311 to move and swing the plurality of air guide vanes 311 upward. The first sub-air guide vane 3111 guides the air flow in the first air outlet channel 14 upward, and the second sub-air guide vane 3112 guides the air flow in the second air outlet channel 15 upward, so that the air flow flows upward in the room through the first air outlet 12 and the second air outlet 13 to perform cooling adjustment on the room.

[0114] Optionally, the connecting rod 312 has a first air guiding surface and a second air guiding surface oppositely arranged in the left-right direction. The first air guiding surface is adjacent to the first air outlet channel 14 and is used to guide the air flow to the first air outlet channel 14, and the second air guiding surface is adjacent to the second air outlet channel 15 and is used to guide the air flow to the second air outlet channel 15. By enabling the connecting rod 312 to have a flow splitting function, the air flow can be respectively guided to the first air outlet channel 14 and the second air outlet channel 15, which can eliminate the need for a separate flow splitting component, further reduce the number of components of the air conditioner and the corresponding installation steps, simplify the structure and reduce the cost, and improve the installation production efficiency.
