[0045] This invention provides an air outlet mechanism, please refer to... Figures 1 to 8 The air outlet mechanism includes a housing 10 and an air outlet unit 20. The housing 10 has an installation opening 11. The air outlet unit 20 includes an air outlet pipe 21, an accessory 22, and a drive assembly. The two openings of the air outlet pipe 21 are a first opening and a second opening, respectively. The accessory 22 is sleeved on the outside of the air outlet pipe 21 and installed at the installation opening 11, so that the first opening and the second opening of the air outlet pipe 21 are located inside and outside the housing 10, respectively. At least a portion of the accessory 22 is made of a flexible material, so that the air outlet pipe 21 can be movably arranged along at least one preset direction. Each preset direction is perpendicular to the center line of the installation opening 11. When there are multiple preset directions, the multiple preset directions are arranged sequentially around the center line of the installation opening 11, and any two adjacent preset directions are arranged at an angle. The drive assembly is connected to the air outlet pipe 21 to drive the air outlet pipe 21 to move along at least one preset direction, so that the air outlet pipe 21 can achieve multi-directional air outlet.

[0046] The direction of air outlet is adjusted by controlling the direction of the air outlet duct 21, replacing the traditional air guide plate; and the use of the air outlet duct 21 to outlet the air can increase the air outlet distance, making the air outlet distance longer, thus solving the problem that the air outlet distance of existing air conditioners is not far enough.

[0047] Specifically, the wall of the air outlet duct 21 includes an inner layer and an outer layer. The inner layer is made of hard, corrosion-resistant alloy materials such as copper and steel, and the outer layer is made of high-density damping material to avoid or reduce the noise problem of the air outlet duct 21.

[0048] In this embodiment, the drive assembly includes at least one drive element 23. Optionally, the drive element 23 is a motor.

[0049] Specifically, when there is one preset direction, there is one drive member 23; the output part of the drive member 23 is connected to the air outlet pipe 21 to drive the air outlet pipe 21 to rotate around the preset axis, thereby causing the air outlet pipe 21 to move along the preset direction; wherein, the extension direction of the preset axis is perpendicular to the preset direction.

[0050] Optionally, when the output part of the drive member 23 is an output shaft, and when the preset direction and the drive member 23 are both the same, the output shaft of the drive member 23 is connected to the air outlet pipe 21, and the axial direction of the output shaft of the drive member 23 is perpendicular to the preset direction, so that the drive member 23 drives the air outlet pipe 21 to rotate around the central axis of its output shaft, thereby causing the air outlet pipe 21 to move in the preset direction; the central axis of the output shaft of the drive member 23 is the preset axis.

[0051] Specifically, when there are multiple preset directions, there are multiple driving components 23. Each driving component 23 is configured in a one-to-one correspondence with a preset direction and a one-to-one correspondence with a preset axis. The multiple driving components 23 are arranged sequentially according to a preset order, with the first driving component 23 in the sequence being the first driving component 23. The output of the first driving component 23 is connected to the air outlet duct 21. Among the driving components 23 other than the first driving component 23, the output of each driving component 23 is connected to the body of the driving component 23 preceding it. That is, according to the arrangement order of the multiple driving components 23, any two adjacent driving components 23 are respectively the preceding driving component 23 and the following driving component 23, with the output of the following driving component 23 connected to the body of the preceding driving component 23, so that the following driving component 23 drives the entire preceding driving component 23 to rotate around the corresponding preset axis of the following driving component 23. The extension direction of the corresponding preset axis of each drive member 23 is perpendicular to the corresponding preset direction, so that each drive member 23 drives the air outlet duct 21 to rotate around the corresponding preset axis, thereby causing the air outlet duct 21 to move along the corresponding preset direction.

[0052] Optionally, when there are multiple preset directions and multiple driving components 23, and when the output part of each driving component 23 is an output shaft, the output shaft of the first driving component 23 is connected to the air outlet duct 21; among the multiple driving components 23 except the first driving component 23, the output shaft of each driving component 23 is connected to the body of the driving component 23 above it; that is, according to the arrangement order of the multiple driving components 23, any two adjacent driving components 23 are respectively the previous driving component 23 and the next driving component 23, and the output shaft of the next driving component 23 is connected to the body of the previous driving component 23, so that the next driving component 23 drives the entire previous driving component 23 to rotate around the central axis of the output shaft of the next driving component 23; the axial direction of the output shaft of each driving component 23 is perpendicular to the corresponding preset direction, so that each driving component 23 drives the air outlet duct 21 to rotate around the corresponding preset axis, thereby causing the air outlet duct 21 to move along the corresponding preset direction. The central axis of the output shaft of each driving component 23 is its corresponding preset axis.

[0053] Optionally, the maximum angle of movement of the air outlet duct 21 in each preset direction is ±75 degrees.

[0054] Specifically, when there are multiple preset directions and multiple driving components 23, the air outlet mechanism also includes a connecting component 25; in any two adjacent driving components 23, the output part of the next driving component 23 and the main body of the previous driving component 23 are connected by the connecting component 25.

[0055] Optionally, the connector 25 is a rod-shaped structure.

[0056] Optionally, when there are multiple preset directions and multiple driving members 23, and when the output part of each driving member 23 is an output shaft, in any two adjacent driving members 23, the output shaft of the next driving member 23 and the main body of the previous driving member 23 are connected by a connector 25.

[0057] For example, the drive assembly includes two drive members 23, namely a first drive member 231 and a second drive member 232; there are two preset directions, namely a first preset direction and a second preset direction; there are two preset axes, namely a first preset axis and a second preset axis; the output part of the first drive member 231 is connected to the air outlet duct 21, and the extension direction of the first preset axis is perpendicular to the first preset direction, so that the first drive member 231 drives the air outlet duct 21 to rotate around the first preset axis, thereby causing the air outlet duct 21 to move along the first preset direction; the output part of the second drive member 232 is connected to the main body of the first drive member 231, and the extension direction of the second preset axis is perpendicular to the second preset direction, so that the second drive member 232 drives both the first drive member 231 and the air outlet duct 21 to rotate around the second preset axis, thereby causing the air outlet duct 21 to move along the second preset direction.

[0058] like Figure 4 As shown, the output portion of the first driving member 231 and the output portion of the second driving member 232 are both output shafts. The output shaft of the first driving member 231 is connected to the air outlet pipe 21. The axial direction of the output shaft of the first driving member 231 is perpendicular to the first preset direction, so that the first driving member 231 drives the air outlet pipe 21 to rotate around the central axis of its output shaft, thereby causing the air outlet pipe 21 to move along the first preset direction. The central axis of the output shaft of the first driving member 231 is the first preset axis.

[0080] Specifically, the air inlet 50 of the air conditioner is located on the outer peripheral surface of the outer casing 10.

[0081] Specifically, the air conditioner also includes an evaporator 30 and a fan 40, both of which are housed within the outer casing 10. Optionally, the fan 40 is a cross-flow fan, with its axis parallel to the axis of the outer casing 10.

[0082] Example 2

[0083] This embodiment also provides an air outlet control method applicable to the air conditioner in Embodiment 1, wherein the axial direction of the outer shell 10 of the air outlet mechanism is parallel to the horizontal direction, and the outer shell 10 is a cylindrical structure.

[0084] Each air outlet pipe 21 of the air outlet mechanism has a first preset direction parallel to the axial direction of the outer casing 10, so that each air outlet pipe 21 can move left and right in the axial direction of the outer casing 10, that is, each air outlet pipe 21 can rotate left and right in the horizontal direction. Each air outlet pipe 21 of the air outlet mechanism has a second preset direction perpendicular to the axial direction of the outer casing 10, so that each air outlet pipe 21 can move up and down in the direction perpendicular to the axial direction of the outer casing 10, that is, each air outlet pipe 21 can rotate up and down in the vertical direction.

[0085] In this embodiment, the air outlet control method includes: establishing the spatial coordinates of the air outlet pipe 21 of each air outlet unit 20 of the human body and the air outlet mechanism; and calculating the movement angle of each air outlet pipe 21 in a first preset direction and a second preset direction based on the spatial coordinates of the human body and the spatial coordinates of each air outlet pipe 21.

[0086] In this embodiment, the method for establishing the spatial coordinates of the air outlet pipe 21 of each air outlet unit 20 of the human body and the air outlet mechanism includes: setting the coordinates of the air outlet pipe 21 of each air outlet unit 20 of the air outlet mechanism to (Xs, Ys, Zs); and setting the spatial coordinates of the human body to include the spatial coordinates of the upper boundary of the human body (X1, Y1, Z1), the spatial coordinates of the lower boundary of the human body (X4, Y4, Z4), the spatial coordinates of the first boundary of the human body (X2, Y2, Z2), and the spatial coordinates of the second boundary of the human body (X3, Y3, Z3); wherein, The distribution direction of the first and second boundaries of the human body is parallel to the X-axis; the Z-axis is parallel to the vertical direction; both the X-axis and Y-axis are parallel to the horizontal plane; multiple air outlet units 20 of each air outlet group are distributed at intervals along the X-axis; the axial direction of the outer shell 10 is the same as the X-axis; the first boundary of the human body is the left or right boundary of the human body, that is, the leftmost or rightmost boundary of the human body; the second boundary of the human body is the right or left boundary of the human body, that is, the rightmost or leftmost boundary of the human body; the top of the human body is the upper boundary of the human body, and the bottom of the human body is the lower boundary of the human body.

[0087] In the specific implementation process, the human body boundary coordinates are taken from the coordinates of the top, bottom, left and right points of the human body.

[0088] In this embodiment, the air outlet mechanism includes three air outlet groups, which are arranged sequentially from top to bottom as the first air outlet group 201, the second air outlet group 202, and the third air outlet group 203.

[0089] It should be noted that for each air outlet duct 21, when the angle of movement of the air outlet duct 21 in the first preset direction is 0, the air outlet direction of the air outlet duct 21 is parallel to the vertical plane. For each air outlet unit 20, the plane perpendicular to the surface where the mounting opening 11 is located is the preset vertical plane of the air outlet unit 20. For each air outlet duct 21, when the angle of movement of the air outlet duct 21 in the second preset direction is 0, the air outlet direction of the air outlet duct 21 is parallel to the preset vertical plane of the air outlet unit 20 to which the air outlet duct 21 is located.

[0090] Optionally, when the outer casing 10 is a cylindrical structure, the preset vertical plane of the air outlet unit 20 of the second air outlet group 202 is parallel to the horizontal plane; the preset vertical plane of the air outlet unit 20 of the first air outlet group 201 is set at an angle to the horizontal plane, and the angle is set obliquely upward; the preset vertical plane of the air outlet unit 20 of the third air outlet group 203 is set at an angle to the horizontal plane, and the angle is set obliquely downward.

[0091] Optionally, when all the air outlet units 20 of the air outlet mechanism are installed on the side of the housing 10 that is parallel to the vertical plane, the preset vertical plane of all the air outlet units 20 is parallel to the horizontal plane; for example, the cross section of the housing 10 perpendicular to its axis is rectangular or other polygonal.

[0092] A preset boundary divides the multiple air outlet units 20 of each air outlet group into two air outlet groups, with each air outlet group having two air outlet groups, namely the first air outlet group and the second air outlet group; each air outlet group includes at least one air outlet unit 20; the first air outlet groups of all three air outlet groups are located on the same side of the preset boundary, and the second air outlet groups of all three air outlet groups are located on the same side of the preset boundary. The orientation of the first air outlet group to the second air outlet group is the same as the orientation of the first boundary to the second boundary of the human body.

[0093] Optionally, the number of air outlet units 20 in the first air outlet group of the three air outlet groups is equal, and the number of air outlet units 20 in the second air outlet group of the three air outlet groups is equal.

[0094] Optionally, in each air outlet group, the number of air outlet units 20 in the first air outlet group is equal to the number of air outlet units 20 in the second air outlet group.

[0095] Optionally, the preset boundary line is a straight line extending in the vertical direction.

[0096] For example, Figure 2 Each air outlet group includes eight air outlet units 20, the first air outlet group of each air outlet group includes four air outlet units 20, and the second air outlet group of each air outlet group includes four air outlet units 20. Figure 2 The straight line L in the diagram is a preset boundary line.

[0097] In this embodiment, when the air conditioner is in cooling mode, such as Figure 2 and Figure 9 As shown, the air outlet control methods include:

[0098] For the first air outlet group 201: by moving the air outlet pipe 21 of each air outlet unit 20 in a second preset direction, the air outlet pipe 21 of each air outlet unit 20 is made to emit air obliquely upward relative to the horizontal plane at an elevation angle arctan(|Z1-Zs| / |Y1-Ys|).

[0099] For the first air outlet group of the second air outlet group 202 and the first air outlet group of the third air outlet group 203: by moving the air outlet pipe 21 of each air outlet unit 20 in a first preset direction, the air outlet pipe 21 of each air outlet unit 20 is made to emit air relative to the vertical plane at an angle arctan(|X2-Xs| / |Y2-Ys|), that is, the angle of movement of the air outlet pipe 21 of each air outlet unit 20 in the first preset direction is arctan(|X2-Xs| / |Y2-Ys|), and the angle between the air outlet direction of the air outlet pipe 21 of each air outlet unit 20 and the X-axis is arctan(|Y2-Ys| / |X2-Xs|) or 180°-arctan(|Y2-Ys| / |X2-Xs|).

[0100] For the second air outlet group of the second air outlet group 202 and the second air outlet group of the third air outlet group 203: by moving the air outlet pipe 21 of each air outlet unit 20 in a first preset direction, the air outlet pipe 21 of each air outlet unit 20 is made to emit air relative to the vertical plane at an angle arctan(|X3-Xs| / |Y3-Ys|), that is, the angle of movement of the air outlet pipe 21 of each air outlet unit 20 in the second preset direction is arctan(|X3-Xs| / |Y3-Ys|), and the angle between the air outlet direction of the air outlet pipe 21 of each air outlet unit 20 and the X-axis is arctan(|Y3-Ys| / |X3-Xs|) or 180°-arctan(|Y3-Ys| / |X3-Xs|).

[0101] In the specific implementation process, each air outlet unit 20 of the first air outlet group 201 ensures that the air outlet is higher than the user's head, and there are no requirements for the left and right movement angle in the first preset direction, with uniform air supply logic as the standard. The vertical movement angle of each air outlet unit 20 in the second air outlet group 202 and the third air outlet group 203 is not required in the second preset direction, with uniform air supply logic as the standard.

[0102] In this embodiment, when the air conditioner is in heating mode, such as Figure 2 and Figure 10 As shown, the air outlet control methods include:

[0103] For the third air outlet group 203: by moving the air outlet pipe 21 of each air outlet unit 20 in the second preset direction, the air outlet pipe 21 of each air outlet unit 20 is made to discharge air obliquely downward relative to the horizontal plane at a depression angle of -arctan(|Z4-Zs| / |Y4-Ys|).

[0104] For the first air outlet group of the second air outlet group 202 and the first air outlet group 201: by moving the air outlet pipe 21 of each air outlet unit 20 in a first preset direction, the air outlet pipe 21 of each air outlet unit 20 is made to emit air relative to the vertical plane at an angle arctan(|X2-Xs| / |Y2-Ys|), that is, the angle of movement of the air outlet pipe 21 of each air outlet unit 20 in the first preset direction is arctan(|X2-Xs| / |Y2-Ys|), and the angle between the air outlet direction of the air outlet pipe 21 of each air outlet unit 20 and the X-axis is arctan(|Y2-Ys| / |X2-Xs|) or 180°-arctan(|Y2-Ys| / |X2-Xs|).

[0105] For the second air outlet group of the second air outlet group 202 and the second air outlet group of the first air outlet group 201: by moving the air outlet pipe 21 of each air outlet unit 20 in the second preset direction, the air outlet pipe 21 of each air outlet unit 20 is made to emit air relative to the vertical plane at an angle of arctan(|X3-Xs| / |Y3-Ys|), that is, the angle of movement of the air outlet pipe 21 of each air outlet unit 20 in the second preset direction is arctan(|X3-Xs| / |Y3-Ys|), and the angle between the air outlet direction of the air outlet pipe 21 of each air outlet unit 20 and the X-axis is arctan(|Y3-Ys| / |X3-Xs|) or 180°-arctan(|Y3-Ys| / |X3-Xs|).

[0106] In the specific implementation process, each air outlet unit 20 of the third air outlet group 203 ensures that the air outlet blows to the user's feet. There are no requirements for the left and right movement angle in the first preset direction, and the uniform air supply logic is taken into account. There are no requirements for the up and down movement angle of each air outlet unit 20 in the second air outlet group 202 and the first air outlet group 201 in the second preset direction, and the uniform air supply logic is taken into account.

[0107] The airflow control method in this embodiment enables the air conditioner to surround the user with airflow, providing a comfortable temperature without the user feeling any draft. Specifically, by locking the user's position using a human sensor, all air outlets 21 are adjusted to prevent airflow from blowing directly onto the user, thus delivering air outside the user's body's boundaries.

[0108] In practice, considering the scattering of wind, the angle needs to be corrected; each of the above-mentioned air outlet angles needs to be compensated by 'a' in a direction away from the human body to ensure that the wind completely avoids the user. Figure 9 and Figure 10 The dashed box surrounding the human figure represents the calculation boundary. Figure 9 and Figure 10 The solid line frame around the human body represents the compensated boundary.

[0109] Specifically, the spatial coordinates of the human body are measured and established using radar.

[0110] In the specific implementation process, such as Figure 11 and Figure 12 As shown, the above air outlet angles can also be compensated by b towards the direction closer to the human body so that the air can blow to the human body, thereby enabling the air conditioner to have the function of blowing air onto people. Figure 11 and Figure 12 The dashed box surrounding the human figure represents the calculation boundary. Figure 11 and Figure 12 The solid line frame around the human body represents the compensated boundary.

[0111] The air outlet control method of this embodiment, which combines the human sense detection device and the multi-angle air supply of the air outlet duct 21, achieves various comfort functions.

The second preset direction of each air outlet pipe 21 of the air outlet mechanism is perpendicular to the axial direction of the outer casing 10, so that each air outlet pipe 21 can move up and down in the direction perpendicular to the axial direction of the outer casing 10, that is, each air outlet pipe 21 can rotate up and down in the vertical direction.

[0131] In practice, the angles mentioned above can be taken as integer multiples of 5, based on the angle values ​​given above.

[0132] In this embodiment, as Figure 13 As shown, the following method is adopted for the movable angle of each air outlet pipe 21 of the air outlet mechanism in the first preset direction:

[0133] The preset boundary divides the multiple air outlet units 20 of each air outlet group into two air outlet groups, and each air outlet group includes at least one air outlet unit 20.

[0134] When an air outlet group includes multiple air outlet units 20, the multiple air outlet units 20 of the air outlet group include an outermost air outlet unit and an innermost air outlet unit; in each air outlet group, the innermost air outlet unit of each air outlet group is located on the side of its outermost air outlet unit that is closer to another air outlet group.

[0135] In each air outlet group, by moving the air outlet pipe 21 of each air outlet unit 20 in a first preset direction, the angle between the air outlet direction of the air outlet pipe 21 of the multiple air outlet units 20 and the vertical plane decreases sequentially from the outermost air outlet unit to the innermost air outlet unit in each air outlet group of the air outlet group; and the air outlet units 20 of the two air outlet groups of the air outlet group are made to outlet air towards both sides of the vertical plane.

[0136] Specifically, making the air outlet units 20 of the two air outlet groups of the air outlet group outlet air out to both sides of the vertical plane means that in each air outlet group, the air outlet units 20 of the two air outlet groups outlet air out to the left and right sides of the vertical plane respectively.

[0137] like Figure 13 As shown, each air outlet group includes eight air outlet units 20; the eight air outlet units 20 are respectively the first air outlet unit 1, the second air outlet unit 2, the third air outlet unit 3, the fourth air outlet unit 4, the fifth air outlet unit 5, the sixth air outlet unit 6, the seventh air outlet unit 7 and the eighth air outlet unit 8; the first air outlet unit 1, the second air outlet unit 2 and the third air outlet unit 3 form one air outlet group, and the first air outlet unit 1 and the third air outlet unit 3 are respectively the outermost air outlet unit and the innermost air outlet unit of the air outlet group; the fourth air outlet unit 4, the fifth air outlet unit 5, the sixth air outlet unit 6, the seventh air outlet unit 7 and the eighth air outlet unit 8 form another air outlet group, and the eighth air outlet unit 8 and the fourth air outlet unit 4 are respectively the outermost air outlet unit and the innermost air outlet unit of the air outlet group.

[0138] The air outlet pipe 21 of the first air outlet unit 1 has a movable angle of 45 degrees in the first preset direction, so that the air outlet direction of the first air outlet unit 1 forms a 45-degree angle with the vertical plane; the air outlet pipe 21 of the second air outlet unit 2 has a movable angle of 30 degrees in the first preset direction, so that the air outlet direction of the second air outlet unit 2 forms a 30-degree angle with the vertical plane; the air outlet pipe 21 of the third air outlet unit 3 has a movable angle of 0 degrees in the first preset direction, so that the air outlet direction of the third air outlet unit 3 is parallel to the vertical plane; the air outlet pipe 21 of the fourth air outlet unit 4 has a movable angle of 15 degrees in the first preset direction, so that the air outlet direction of the fourth air outlet unit 4 forms a 15-degree angle with the vertical plane; the fifth... The air outlet pipe 21 of the air outlet unit 5 has a movable angle of 30 degrees in the first preset direction, so that the air outlet direction of the fifth air outlet unit 5 forms a 30-degree angle with the vertical plane; the air outlet pipe 21 of the sixth air outlet unit 6 has a movable angle of 45 degrees in the first preset direction, so that the air outlet direction of the sixth air outlet unit 6 forms a 45-degree angle with the vertical plane; the air outlet pipe 21 of the seventh air outlet unit 7 has a movable angle of 60 degrees in the first preset direction, so that the air outlet direction of the seventh air outlet unit 7 forms a 60-degree angle with the vertical plane; the air outlet pipe 21 of the eighth air outlet unit 8 has a movable angle of 75 degrees in the first preset direction, so that the air outlet direction of the eighth air outlet unit 8 forms a 75-degree angle with the vertical plane.

[0139] Specifically, the first air outlet unit 1, the second air outlet unit 2, and the third air outlet unit 3 outlet air to the left side of the vertical plane, while the fourth air outlet unit 4, the fifth air outlet unit 5, the sixth air outlet unit 6, the seventh air outlet unit 7, and the eighth air outlet unit 8 outlet air to the right side of the vertical plane.

[0140] Optionally, the first air outlet unit 1 is located on the side of the eighth air outlet unit 8 closest to the wall.

[0141] The air outlet control method in this embodiment enables the air conditioner to achieve uniform airflow. Upon normal startup, it defaults to whole-room airflow, using multiple air outlets 21 at multiple angles to ensure uniform indoor temperature. To achieve uniform indoor temperature, considering the different air densities during cooling and heating, the heating and cooling scenarios are discussed separately.

[0142] Example 4

[0143] This embodiment also provides an air outlet control method applicable to the air conditioner in Embodiment 1. When the outer casing 10 is a cylindrical structure, preferably a circular structure, the air inlet 50 of the air conditioner is located on one side of the air outlet mechanism along the circumference of the outer casing 10.

[0144] The air outlet control method includes: in order to more quickly raise (during heating) or lower (during cooling) the temperature of the indoor heat exchanger, the air outlet units 20 of at least one air outlet group of the air outlet mechanism are directed as far as possible toward the air inlet 50, so that the air blown out by the air outlet units 20 of at least one air outlet group of the air outlet mechanism can enter the air conditioner through the air inlet 50, forming an airflow short circuit, thereby rapidly raising (during heating) or lowering (during cooling) the temperature of the entire indoor evaporator, and thus helping the air conditioning system establish a high-low pressure difference between the compressor suction port and the exhaust port when the compressor is running at low frequency, and simultaneously establishing a temperature difference between the outlet air temperature and the indoor air temperature; after the compressor frequency increases, all air outlet units 20 of the air outlet mechanism are immediately opened to reduce the temperature preheating or precooling time of the indoor heat exchanger after the compressor frequency increases. The air outlet control method of this embodiment can shorten the start-up time of cooling and heating, thereby achieving rapid cooling and heating, so that the air conditioner has the function of rapid cooling and heating.

[0145] like Figure 14 As shown, the air outlet mechanism includes three air outlet groups, which are arranged sequentially from top to bottom as the first air outlet group 201, the second air outlet group 202, and the third air outlet group 203; the air inlet 50 is located at the lower part of the outer shell 10, which is the air intake method of the lower air inlet; the third air outlet group 203 is the air outlet group closest to the air inlet 50, and mainly relies on the air blown out by the air outlet unit 20 of the third air outlet group 203 to enter the air inlet 50.

[0146] In the specific implementation process, all air outlet units 20 of the air outlet mechanism can be moved downward in the second preset direction so that each air outlet unit 20 can move to its maximum angle of movement in the second preset direction.

[0147] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0148] In the air outlet mechanism provided by the present invention, the air outlet mechanism includes a housing 10 and an air outlet unit 20. The housing 10 has an installation opening 11. The air outlet unit 20 includes an air outlet pipe 21, a fitting 22, and a drive assembly. The two openings of the air outlet pipe 21 are a first opening and a second opening, respectively. The fitting 22 is sleeved on the outside of the air outlet pipe 21 and installed at the installation opening 11, so that the first opening and the second opening of the air outlet pipe 21 are located on the inside and outside of the housing 10, respectively. At least a portion of the fitting 22 is made of a flexible material, so that the air outlet pipe 21 can be movably arranged along at least one preset direction. Each preset direction is perpendicular to the center line of the installation opening 11. When there are multiple preset directions, the multiple preset directions are arranged sequentially around the center line of the installation opening 11, and any two adjacent preset directions are arranged at an angle. The drive assembly is connected to the air outlet pipe 21 to drive the air outlet pipe 21 to move along at least one preset direction, so that the air outlet pipe 21 can achieve multi-directional air outlet.

[0149] The direction of air outlet is adjusted by controlling the direction of the air outlet duct 21, replacing the traditional air guide plate; and the use of the air outlet duct 21 to outlet the air can increase the air outlet distance, making the air outlet distance longer, thus solving the problem that the air outlet distance of existing air conditioners is not far enough.
