Figure 5 ,for Figure 4 A partial enlarged view of point A in the middle.

[0054] In the embodiment of the present invention, Figure 1 As shown, combined with Figure 2 and Figure 3 As shown, the air outlet device includes: a wind wheel 17, a bracket 11 and a guide block 2; the wind wheel 17 is arranged on the bracket 11, and the wind wheel 17 rotates to form a negative pressure, which attracts the airflow around the bracket 11 and blows out an airflow with a certain wind speed from one side of the bracket 11; the guide block 2 is arranged on the bracket 11, and the guide block 2 is used to change the wind direction of the airflow blown out by the bracket 11.

[0055] Optionally, the bracket 11 has a mounting slot 12, a first air port 13 and a second air port 14, wherein the mounting slot 12 is connected to the first air port 13 and the second air port 14. The wind wheel 17 is arranged in the mounting slot 12; wherein the first air port 13 can be arranged corresponding to the peripheral area of ​​the bracket 11, and when the wind wheel 17 rotates, air is sucked from the first air port 13; the second air port 14 is another opening spaced apart from the first air port 13, and when the wind wheel 17 rotates, airflow with a certain wind speed can be blown out from the second air port 14.

[0056] On the other hand, the guide block 2 is arranged on the inner wall of the mounting groove 12 , and the guide block 2 is spaced apart from and arranged opposite to the wind wheel 17 .

[0057] Optionally, the air outlet device includes a plurality of guide blocks 2, and two adjacent guide blocks 2 are arranged at intervals. Optionally, the plurality of guide blocks 2 are arranged in parallel and at intervals along the axial direction of the wind wheel 17. It can be understood that among the plurality of guide blocks 2, some of the guide blocks 2 can be arranged in the same direction, and the other part of the guide blocks 2 can be arranged in another direction, specifically:

[0058] On the one hand, multiple guide blocks 2 can be arranged in the same direction, for example, multiple guide blocks 2 are arranged at an angle away from the ground and upward. In this case, after the airflow passes through the guide blocks 2, it forms wind blowing upward. Alternatively, multiple guide blocks 2 are arranged at an angle facing the ground and downward, such as Figure 6 As shown, at this time, the airflow flows through the guide block 2 to form wind blowing downward.

[0059] On the other hand, the guide block 2 located above the reference line can be set at an angle away from the ground and upward, and the guide block 2 located below the reference line can be set at an angle facing the ground and downward, so that wind can be blown upward and downward at the same time. The central horizontal line refers to a line segment set perpendicular to the length direction of the bracket 11, and the line segment is used to equally divide the bracket 11 into two parts.

[0060] In this embodiment, by setting the wind wheel 17 on the mounting groove 12 of the bracket 11, when the wind wheel 17 rotates, a negative pressure is formed in the mounting groove 12, so that the gas outside the bracket 11 flows to the wind wheel 17 and blows out from the second air outlet 14; wherein, guide blocks 2 are arranged at intervals on the inner wall of the mounting groove 12, and one side of the guide block 2 is arranged toward the first air outlet, so that after the rotation of the wind wheel 17, the formed airflow can flow through one side of the guide block 2, and then blow out directional wind. On the one hand, multiple guide blocks 2 are arranged at intervals on the inner wall of the mounting groove 12, and the multiple guide blocks 2 can be arranged in the same direction, for example: multiple guide blocks 2 are arranged at an angle away from the ground and upward, at this time, after the airflow flows through the guide block 2, it forms a wind blowing upward; or multiple guide blocks 2 are arranged at an angle facing the ground and downward, at this time, after the airflow flows through the guide block 2, it forms a wind blowing downward. On the other hand, the guide block 2 located above the reference line can be set at an angle away from the ground and upward, and the guide block 2 located below the reference line can be set at an angle facing the ground and downward, so that the wind can be blown upward and downward at the same time. On the other hand, other airflow guide devices can be used to further adjust the direction of the airflow, wherein the other airflow guide devices can be swing blades. The air outlet device of the present invention improves the directionality of the air outlet of the air conditioner.

[0061] Optionally, the central horizontal line of the bracket 11 may be a line segment that passes through the bracket 11 laterally, and the line segment may be adjusted upward or downward according to actual processing requirements.

[0062] It can be understood that the air outlet device may also include a motor assembly (not shown in the figure), which is arranged on the bracket 11 and spaced apart from the mounting groove 12; the output shaft of the motor assembly is connected to one end of the wind wheel 17 to drive the wind wheel 17 to rotate, thereby causing the wind wheel 17 to generate negative pressure in the mounting groove 12.

[0063] In one embodiment of the present invention, Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the bracket 11 includes a frame 15 and a volute tongue 16. The frame 15 is provided with a receiving space, the volute tongue 16 is arranged in the receiving space (not shown) and connected to the frame 15, and the volute tongue 16 and the inner wall of the frame 15 enclose the mounting groove 12, the first air outlet 13 and the second air outlet 14. It can be understood that the volute tongue 16 is a baffle structure, and the volute tongue 16 is arranged adjacent to the second air outlet 14; the wind wheel 17 rotates, so that air can enter from the end of the volute tongue 16 close to the wind wheel 17, and after passing through the area where the wind wheel 17 generates negative pressure, it is blown out from the second air outlet 14. Conventionally, the volute tongue 16 and the inner wall of the receiving space enclose a through groove (not shown), and the through groove is connected to the mounting groove 12.

[0064] On the other hand, the wind wheel 17 is arranged on the frame 15, and the wind wheel 17, the volute tongue 16 and the inner wall of the frame 15 enclose an air duct (not shown in the figure), and the guide block 2 is connected to the inner wall of the frame 15, that is, the guide block 2 is located in the air duct. It can be considered that the through groove enclosed by the volute tongue 16 and the inner wall of the accommodating space connects the space formed by the wind wheel 17 and the inner wall of the installation groove 12 to form an air duct.

[0065] In this embodiment, the guide block 2 is arranged in the air duct. When the formed airflow blows toward the air duct, the airflow moves along the inner wall of the air duct; and, in the presence of the guiding effect of the guide block 2, the airflow moves along the side of the guide block 2 to change the moving direction of part of the airflow, so that the airflow can be discharged through one side of the guide block 2.

[0066] It can be understood that the side where the guide block 2 is connected to the frame 15 is defined as the first side, and the other side of the guide block 2 extending away from the frame 15 is defined as the second side. The plane formed by connecting the first side and the second side and the plane perpendicular to the axial direction of the wind wheel 17 are set at an angle.

[0067] Optionally, the guide block 2 may be fixed to the bracket 11 by secondary thermoplasticization.

[0068] Optionally, the guide block 2 may be integrally injection molded with the bracket 11 .

[0069] Optionally, the guide block 2 may be fixed to the bracket 11 by ultrasonic welding.

[0070] In one embodiment of the present invention, Figure 3 , Figure 4 as well as Figure 5 As shown, the plane perpendicular to the length direction of the wind wheel 17 is the horizontal plane; the two endpoints connecting the guide block 2 and the inner wall of the mounting groove 12 are defined as the first endpoint and the second endpoint, and the angle formed between the line connecting the first endpoint and the second endpoint and the horizontal plane is α; wherein, -90°﹤α﹤0°, or; 90°﹤α﹤180°.

[0071] It can be understood that the table top for placing the air outlet device is the ground, and in this case, the ground is arranged parallel to the horizontal plane.

[0072] The X-axis of the XY two-dimensional coordinate system with the horizontal plane as one coordinate, and the second endpoint as the origin of the XY two-dimensional coordinate system; the Y-axis below the X-axis is indicated as -90°, and the Y-axis above the X-axis is indicated as 90°; α is the angle between the line connecting the first endpoint and the second endpoint and the X-axis, specifically:

[0073] When 0°﹤α﹤90°, combined Figure 4 , Figure 5 as well as Figure 6As shown, the distance of the first end point relative to the ground is greater than the distance of the second end point relative to the ground, so that the angle formed between the line connecting the first end point and the second end point and the horizontal plane is 0° to 90°. At this time, the wind blown out of the air outlet device is directed toward the ground after passing through the guide block 2 facing the side of the wind wheel 17. Specifically, when the air conditioner is in heating mode, the warm air can be blown to the ground as much as possible to improve indoor comfort; when the air conditioner is in cooling mode, the cold air is blown to the ground to avoid blowing directly on the human body.

[0074] When -90°﹤α﹤0°, the distance of the first endpoint relative to the ground is smaller than the distance of the second endpoint relative to the ground, so that the angle formed between the line connecting the first endpoint and the second endpoint and the horizontal plane is -90° to 0°. At this time, the wind blown out by the air outlet device is guided by the guide block 2 facing the side of the wind wheel 17, so that the blown wind has a direction away from the ground. Specifically, when the air conditioner is in cooling mode, the cold air is blown to the area above the air conditioner to avoid blowing directly on the human body. When the air conditioner is in heating mode, the warm air can be blown to the area above the air conditioner to avoid blowing directly on the human body, so as to improve indoor comfort.

[0075] In the actual application of this embodiment, a horizontal auxiliary line is made in the middle of the air outlet device, and the horizontal auxiliary line divides the air outlet device into a first body (not marked in the figure) and a second body (not marked in the figure). The air duct of the first body and the air duct of the second body are mirror-set based on the horizontal auxiliary line. At this time, the angles formed between the multiple guide blocks in the air duct of the first body and the horizontal plane are all 0° to 90°, and the angles formed between the multiple guide blocks in the air duct of the second body and the horizontal plane are all -90° to 0°. In this way, when the air conditioner is in cooling mode, cold air blows to the upper area of ​​the air conditioner and the ground to avoid blowing directly on the human body; on the other hand, when the air conditioner is in heating mode, warm air blows to the upper area of ​​the air conditioner and the ground to accelerate the rise of indoor temperature, avoid blowing directly on the human body, and improve the comfort of the human body.

[0076] In summary, similarly, when the first endpoint is the origin of the XY two-dimensional coordinate system, when -90°﹤α﹤0°, the wind blown out by the air outlet device has a directivity toward the ground. When 0°﹤α﹤90°, the wind blown out by the air outlet device has a directivity toward the direction away from the ground.

[0077] In one embodiment of the present invention, the side of the guide block 2 facing the first air outlet is the windward surface 21, and the windward surface 21 is arranged in an arc shape. In other words, the side of the guide block 2 connected to the frame 15 is defined as a connecting surface (not shown), the windward surface 21 is arranged adjacent to the connecting surface, and the windward surface 21 is arranged facing the direction of the first air outlet.

[0078] In the actual application of this embodiment, the wind wheel 17 rotates so that radial air is sucked into the mounting groove 12 and radially discharged gas is formed. In this way, in order to make the discharged gas directional and blow the gas above the air-conditioning indoor unit or to the floor, the windward surface 21 of the guide block 2 is arranged to face the first air outlet, so that when the gas is blown out, it can have a certain directionality after being guided by the windward surface 21.

[0079] In this embodiment, the windward surface 21 may be provided as a concave arc surface, that is, an arc-shaped groove is provided on the windward surface 21 , and after the airflow is blown to the windward surface 21 , it may move along the arc-shaped groove to improve the directivity of the air outlet.

[0080] Optionally, the windward surface 21 may also be a convex surface. In this way, under the premise of changing the directionality of the airflow, the airflow can be moved along the convex surface so that the airflow is blown out smoothly.

[0081] In one embodiment of the present invention, a plurality of guide blocks 2 are arranged in parallel and spaced apart in sequence along the axial direction of the wind wheel 17 so that the blown wind is blown out in the same direction.

[0082] In one embodiment of the present invention, the plurality of guide blocks 2 and the bracket 11 are integrally formed to achieve structural integration and avoid accidents in which the guide blocks 2 fall off the bracket 11 .

[0083] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the thickness H of the guide block 2 is defined to satisfy 0.5 mm ≤ H ≤ 15 mm. By adopting a thickness of 0.5 mm to 15 mm, the guide block 2 has a certain thickness and avoids excessive obstruction of the flow of air.

[0084] Optionally, the thickness of the guide block 2 is 0.5 mm ≤ H ≤ 10 mm.

[0085] In one embodiment of the present invention, Figure 4 As shown, the transverse section of the bracket 11 is used as the reference plane, the transverse section is perpendicular to the axial direction of the wind wheel 17, and the first end point and the second end point of the guide block 2 are defined to form two projection points to the transverse section. The line connecting the two projection points is the guide block. The span is L, and the shortest distance from the first air outlet to the second air outlet of the air duct is D, D / 5≤L≤D. For example: the horizontal length of the air duct in the transverse section is 10cm, and the length of the guide block 2 in the transverse section is at least 2cm.

[0086] It can be understood that the first end point and the second end point form two vertical lines with the shortest distance to the transverse section, and the two vertical lines intersect at the transverse section to form two projection points.

[0087] Of course, it can be considered that the guide block 2 can also start at one end of the air duct adjacent to the first air outlet 13 and end at one end of the air duct adjacent to the second air outlet 14, and the guide block 2 is arranged obliquely from the start to the end.

[0088] Optionally, the width of the guide block 2 is determined according to the number of guide blocks 2 to be added and the gap. Optionally, the guide block 2 protrudes 1 to 10 mm from the inner wall of the frame 15 to the air duct. In other words, the straight-line distance between any point on one end surface of the guide block 2 away from the groove wall of the installation groove 12 and the groove wall of the installation groove 12 is 1 mm to 10 mm. In other words, the width of the guide block 2 is the length of the second side edge of the guide block 2 described above extending toward the side away from the frame 15.

[0089] Optionally, the width of the guide block 2 is 2 mm to 8 mm.

[0090] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the frame 15 is provided with two spaced-apart accommodating spaces.

[0091] The bracket 11 includes two volute tongues 16 , each of which is connected to the frame 15 and is respectively accommodated in each accommodation space. Each volute tongue 16 and the inner wall of each accommodation space enclose a mounting groove 12 , a first air outlet 13 and a second air outlet 14 .

[0093] The air outlet device in this embodiment includes two wind wheels 17 . Both wind wheels 17 are connected to the frame 15 . Each wind wheel 17 is disposed in each installation slot 12 .

[0094] In this embodiment, two wind wheels 17 are installed on the frame 15 to increase the total amount of airflow output by the air outlet device per unit time and improve the speed of adjusting the indoor temperature.

[0095] In one embodiment of the present invention, the guide block 2 is disposed opposite to the volute tongue 16 .

[0096] In one embodiment of the present invention, the two mounting grooves 12 are mirror-imaged with the vertical center plane of the bracket 11, and the notches of the two mounting grooves 12 are arranged in opposite directions. A guide block 2 is arranged on the inner wall surface of each mounting groove 11, and the guide block 2 is arranged adjacent to the vertical center plane.

[0097] Optionally, the two installation slots 12 are a first slot body and a second slot body, and the number of guide blocks 2 in the first slot body may be different from the number of guide blocks 2 in the second slot body. Of course, the number of guide blocks 2 in the first slot body may be equal to the number of guide blocks 2 in the second slot body.

[0098] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the air outlet device also includes: a grille 3, a first air sweeping assembly 4 and a second air sweeping assembly 5.

It can be understood that the first air sweeping assembly 4 is arranged adjacent to the grille 3. The second air sweeping assembly 5 is connected to the bracket 11 and is located on the side of the first air sweeping assembly 4 facing away from the grille 3, and the second air sweeping assembly 5 is used for vertical air sweeping. It can be understood that the second air sweeping assembly 5 is arranged in parallel with the first air sweeping assembly 4.

[0099] The grille 3 is provided with a plurality of air holes (not marked in the figure).

[0100] On the other hand, the first air sweeping component 4 may include a connecting rod (not shown) and a plurality of fan blades (not shown) arranged on the connecting rod.
