[0080] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0081] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0082] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0083] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0084] The air supply scheme of traditional air conditioners is generally directional air supply or up-and-down or left-and-right air sweeping. The blown cold air is relatively hard and blows directly at the user, which is likely to cause discomfort to the user.

[0085] To solve the above problems, existing air conditioners usually set a wind-dispersing structure at the air outlet to soften the blown air. However, the wind-dispersing form of the existing wind-dispersing structure is single, unable to achieve changes in blowing, and is relatively monotonous in visual effects.

[0086] In view of the above, the present invention provides an air conditioner, and the air conditioner includes an air-conditioning indoor unit. Among them, the air-conditioning indoor unit includes a wall-mounted air-conditioning indoor unit, a ceiling-mounted air-conditioning indoor unit, or a floor-standing air-conditioning indoor unit. For the convenience of understanding, in the following embodiments, the air conditioner is taken as an example of a floor-standing air-conditioning indoor unit for description. Please refer to Figures 1 to 30 As shown in the accompanying drawings, a specific embodiment of the air-conditioning indoor unit 100 provided by the present invention is shown.

[0087] Please refer to Figures 6 to 9, the air conditioner indoor unit 100 provided by the present invention includes a housing 101, two air diffuser plates, and a connecting rod 130 and louvers 140. Among them, the housing 101 has an air outlet 103; both of the two air diffuser plates are provided with air diffusing openings. One of the two air diffuser plates is a first air diffuser plate 110, and the other is a second air diffuser plate 120. The first air diffuser plate 110 is arranged at the air outlet 103; the second air diffuser plate 120 has a rotation axis arranged along the air outlet direction. The second air diffuser plate 120 rotates relative to the first air diffuser plate 110 around the rotation axis, so that the overlapping area of the air diffusing openings of the two air diffuser plates projected along the air outlet direction is variably arranged; the connecting rod 130 is connected to the second air diffuser plate 120 to drive the second air diffuser plate 120 to rotate by moving the connecting rod 130.

[0088] In the technical solution provided by the present invention, during the process of the connecting rod driving the second air diffuser plate 120 to rotate, the relative position between the second air diffuser plate 120 and the first air diffuser plate 110 continuously changes, so that the overlapping area of the second air diffusing opening 121 and the first air diffusing opening 111 projected along the air outlet direction continuously changes, thereby changing the air diffusing form of the air conditioner indoor unit 100 and optimizing the air supply effect and visual effect.

[0089] Please refer to Figures 1 to 2 , the air conditioner indoor unit 100 generally has a housing 101. An air outlet passage 102 is formed inside the housing 101. An air outlet 103 communicating with the air outlet passage 102 is provided on the outer wall of the housing 101 for air flow to flow out from the air outlet passage 102 through the air outlet 103.

[0090] In an embodiment, the air outlet 103 extends in the vertical direction, and the first air diffuser plate 110 is arranged in a longitudinal shape covering the air outlet 103; a plurality of second air diffuser plates 120 are provided, and the plurality of second air diffuser plates 120 are arranged at intervals in the vertical direction and are adapted to be arranged with respect to the first air diffuser plate 110.

[0091] The specific form of the air outlet 103 is not limited in this design. Specifically, the forming position of the air outlet 103 can be the side, top or bottom of the housing 101; the shape of the air outlet 103 can be set as a vertically elongated shape, an oval shape along the vertical direction, etc. Among them, the vertically elongated setting can reasonably utilize the housing plate surface of the air conditioner indoor unit 100, which helps to expand the air supply area. Further, in order to expand the air dispersion amount, the first air dispersion plate 110 is arranged to cover the air outlet 103; and a plurality of second air dispersion plates 120 are arranged at intervals on the first air dispersion plate 110. Each two adjacent second air dispersion plates 120 can be adjacently arranged or spaced apart. The shape of the first air dispersion plate 110 is adapted to the shape of the second air dispersion plate 120. Specifically, the width of the second air dispersion plate 120 can be set to be adapted to the width of the first air dispersion plate 110, so as to ensure that the entire plate surface is oppositely arranged with the first air dispersion plate 110 during the rotation of the second air dispersion plate 120. In specific applications, the shape of the second air dispersion plate 120 can be circular or others. Among them, when the second air dispersion plate 120 is circular, the diameter of the second air dispersion plate 120 is set to be equivalent to the width of the first air dispersion plate 110.

[0092] The number of the air outlets 103 is also not limited, and can be one, or at least two arranged at intervals along the vertical direction or along the circumferential direction of the housing 101. Based on this, in an embodiment, two of the first air dispersion plates 110 and the second air dispersion plates 120 are provided corresponding to the two air outlets 103. The structures of the first air dispersion plate 110 and the second air dispersion plate 120 of each air outlet 103 are independent of each other. The driving device can be commonly set as one corresponding to the two air outlets 103, or can be respectively set as two corresponding to the two air outlets 103.

[0093] The air conditioner indoor unit 100 generally further includes a blower wheel 200 and an evaporator 300. The evaporator 300 is arranged on the air inlet side of the housing 101, and the blower wheel 200 is arranged in the air outlet passage 102 to output the air flow toward the air outlet 103. Among them, the specific form of the blower wheel 200 is not limited, and can be an axial flow blower wheel or a double cross-flow blower wheel, etc.

[0094] Further, in an embodiment, the air conditioner indoor unit 100 further includes a louver 133. One end of the louver 133 is movably connected to the connecting rod 130, and the other end is connected to the first air dispersion plate 110 and / or the second air dispersion plate 120, so as to drive the louver 133 and the second air dispersion plate 120 to rotate by moving the connecting rod 130. The movement of the connecting rod 130 can, while realizing the rotation of the second air dispersion plate 120, also change the air flow direction blowing toward the second air dispersion plate 120 by driving the louver 140 to flip, which helps to further enrich the air dispersion form of the air conditioner indoor unit 100.

[0095] Please refer to Figure 8 and Figure 9 Two air diffuser plates are stacked in the air outlet direction within the air outlet passage 102, and the first air diffuser plate 110 is arranged closer to the air outlet 103 than the second air diffuser plate 120; the first air diffuser plate 110 is set to be adapted to the shape and size of the air outlet 103, so that during operation, the air flow output through the air outlet 103 can be softened under the action of the two air diffuser plates. The second air diffuser plate 120 has a rotation axis arranged in the air outlet direction, so that the second air diffuser plate 120 is substantially perpendicular to the air outlet direction and has a larger bearing area for the air flow to pass through, thereby being able to soften more air flow. It can be understood that since the air outlet passage 102 is generally arranged to bend and extend, that is, when the relative position between the second air diffuser plate 120 and the air outlet passage 102 is different, the rotation axis of the second air diffuser plate 120 also changes accordingly. However, for the sake of easy understanding, in the following embodiments, both air diffuser plates are arranged closer to the air outlet 103 as an example to reduce the space occupied by the air outlet passage 102, so that after the air flow is rectified in the air outlet passage 102, it is output through the two air diffuser plates.

[0096] For the purpose of distinction, in the following embodiments, the air diffuser openings of the first air diffuser plate 110 are the first air diffuser openings 111, and the air diffuser openings of the second air diffuser plate 120 are the second air diffuser openings 121. Both the first air diffuser openings 111 and the second air diffuser openings 121 can be one air diffuser opening or a set of multiple air diffuser openings. During the operation of the air conditioner indoor unit 100, the second air diffuser plate 120 keeps rotating relative to the first air diffuser plate 110, so that the overlapping area of the air diffuser openings of the two changes continuously, thereby ensuring that the ventilation volume and ventilation form through the two air diffuser plates change in real time and have a dynamic visual effect, which helps to produce a cooling effect physically and psychologically.

[0097] One end of the louver 140 is connected to the second air diffuser plate 120. It can be understood that this end of the louver 140 can be integrally formed with the second air diffuser plate 120, or can be separately arranged from the second air diffuser plate 120 and then installed at the second air diffuser plate 120 by means of snap fixation, screw fixation or bonding fixation, etc. The louver 140 can be arranged between the first air diffuser plate 110 and the second air diffuser plate 120, or the louver 140 can protrude on the side of the second air diffuser plate 120 facing away from the first air diffuser plate 110. In this way, when the first air diffuser plate 110 and the second air diffuser plate 120 are arranged adjacent to each other, by changing their relative positions, the air diffusing effect can be better and the dynamic visual effect can be more obvious.

[0098] The shape of the louver 140 is not limited. However, in order to achieve the air guiding function, the louver 140 is generally arranged in a plate shape, and the louver 140 has a first side connected to the second air diffusing plate 120 and a second side opposite to the first side. The second side of the louver 140 is arranged in an arc shape, and in the direction from the first side to the second side of the louver 140, the louver 140 is arranged with a gradually decreasing thickness to reduce the air resistance.

[0099] It can be understood that the specific shape and size of the second air diffusing plate 120 are not limited. For example, it can be set as a rectangle, a circle, an ellipse or other shapes; a plurality of second air diffusing plates 120 can be arranged on the plane where the first air diffusing plate 110 is located. Based on this, please refer to Figures 11 to 13 , the louver 140 can include a plurality of first louvers corresponding to a plurality of second air diffusing plates 120; or include a plurality of second louvers rotatably mounted on the first air diffusing plate 110; or simultaneously have a plurality of the above-mentioned first louvers and a plurality of second louvers. At this time, the second louvers are arranged between two first louvers, and the second louvers are provided with a connecting shaft 142 facing the first air diffusing plate 110, and the second louvers are rotatably mounted on the first air diffusing plate 110 through the connecting shaft 142. The setting of the connecting shaft 142 can determine the rotation axis of the second louver, so as to drive the two first louvers adjacent to the second louver to rotate together. When the rotation axes of a plurality of second louvers are substantially collinear, all the louvers 140 can be rotated synchronously.

[0100] The connecting rod 130 is respectively connected to the second air diffusing plate 120 and the louver 140, so that a plurality of second air diffusing plates 120 and a plurality of louvers 140 rotate synchronously. The specific setting of the connecting rod 130 is not limited. For example, it is set as a rod-shaped structure extending along the arrangement direction of a plurality of second air diffusing plates 120 and telescopically movable along this direction, or set as other structures that can also play a linkage role, such as a plurality of gears meshing in sequence along the arrangement direction of a plurality of second air diffusing plates 120, etc.

[0101] In order to realize the intelligence of the air conditioner indoor unit 100, in an embodiment, the air conditioner indoor unit 100 further includes a driving device, and the driving device is used to respectively drive the first air diffusing plate 110 to rotate and the connecting rod 130 to move. By driving the connecting rod 130 to move, the driving device can synchronously drive the second air diffusing plate 120 and the louver 140 to rotate.

[0102] Please refer to Figures 6 to 7, in one embodiment, the first air diffuser plate 110 is rotatably mounted on the housing 101 to rotate to open and close the air outlet 103. The rotation axis of the first air diffuser plate 110 can be set along the length direction of the first air diffuser plate 110, along the width direction of the first air diffuser plate 110, or along any direction on the plate surface of the first air diffuser plate 110 according to actual needs. In order to improve the aesthetics at the air outlet 103 of the air conditioner indoor unit 100, in the following embodiments, the rotation axis of the second air diffuser plate 120 is set along the length direction of the first air diffuser plate 110, and the rotation axis of the first air diffuser plate 110 is different from the plane where the first air diffuser plate 110 is located, so that the first air diffuser plate 110 can revolve around its rotation axis, and can rotate to cover the air outlet 103 and rotate to connect the air outlet 103 and the air outlet passage 102.

[0103] Please refer to Figures 3 to 5 , in one embodiment, the driving device includes a first driver 151 for driving the first air diffuser plate 110 to rotate; two rotating shaft portions 115 are respectively convexly provided at opposite ends of the first air diffuser plate 110, and the housing 101 is correspondingly provided with two shaft hole portions 104 rotatably installed and matched with the two rotating shaft portions 115. Among them, the first driver 151 is drivingly connected to one of the rotating shaft portions 115. Specifically, the first driver 151 can be set as a motor or a rotary cylinder, etc., and has a rotating output shaft. Opposite ends of the first air diffuser plate 110 can be convexly provided with two connecting plates, the rotating shaft portions 115 are respectively convexly provided on the two connecting plates, and are rotatably arranged relative to the shaft hole portions 104; an installation hole is provided in the middle of the rotating shaft portion 115, and the installation hole is connected to the rotating output shaft of the first driver 151. Of course, in the above, if the rotating shaft portion 115 is provided on the housing 101 and the shaft hole portion 104 is provided on the connecting plate, the purpose of driving the first air diffuser plate 110 to rotate by the first driver 151 can also be achieved, which will not be elaborated here.

[0104] In the above, the first air deflector 110 can be fixedly installed on the housing 101 through the installation cooperation between the rotating shaft portion 115 and the shaft hole portion 104; alternatively, the first driver 151 can be fixedly installed on the housing 101, and the first air deflector 110 is fixedly installed on the housing 101 through the connection cooperation between the rotating shaft portion 115 and the rotating output shaft. At this time, the assembly distance between the rotating shaft portion 115 connected to the first driver 151 and the corresponding shaft hole portion 104 is 1 to 5 mm. It can be understood that if the assembly distance is relatively large, it is likely to cause unstable installation between the rotating shaft portion 115 and the shaft hole portion 104; conversely, if the assembly distance is relatively small, the frictional damping between the rotating shaft portion 115 and the shaft hole portion 104 will increase. Therefore, in order to obtain a better installation effect, in this embodiment, the assembly distance is set to 1 to 5 mm.

[0105] Further, in an embodiment, the first air deflector 110 is arc-shaped, that is, the plate surface of the first air deflector 110 is arc-shaped, so that within the limited air outlet 103, the plate surface of the first air deflector 110 is increased, thereby increasing the air dispersion area and helping to optimize the air dispersion effect.

[0106] The plate surface of the first air deflector 110 can protrude into the air outlet passage 102 or protrude out of the air outlet 103. Figure 6 and Figure 7 As shown, the plate surface of the first air deflector 110 protrudes out of the air outlet 103, and the opposite sides of the first air deflector 110 are generally flush with the edge of the air outlet 103, which helps to improve the aesthetics of the overall structure of the machine. Based on the above features, further, the inner wall surface of the air outlet passage 102 can be set to be arc-shaped and adapted to the plate surface of the first air deflector 110, so that when the first air deflector 110 rotates to a position close to the inner wall surface of the air outlet passage 102 on one side of the air outlet 103 to open the air outlet 103, the plate surface of the first air deflector 110 fits better with the inner wall surface of the air outlet passage 102.

[0107] Furthermore, the air conditioner indoor unit 100 further includes a door body 105, and the door body 105 is rotatably installed on the housing 101 to rotate to open and close the air outlet 103. Based on this, the air conditioner indoor unit 100 further includes a control device, and the control device is electrically connected to the door body 105 and the first driver 151. When the control device controls the door body 105 to open and the first air deflector 110 to open, the air conditioner indoor unit 100 is in the normal air outlet mode; when the control device controls the door body 105 to open and the first air deflector 110 to close, the air conditioner indoor unit 100 is in the no-wind feeling mode; when the control device controls the door body 105 to close the air outlet 103.

[0108] The first air-diffusing plate 110 and the second air-diffusing plate 120 can both be installed on the housing 101; alternatively, in one embodiment, the opposite sides of the first air-diffusing plate 110 extend towards each other to form a plate-like structure 112 for installing the second air-diffusing plate 120. The first air-diffusing plate 110 is rotatably installed on the housing 101, and the second air-diffusing plate 120 is rotatably installed on the plate-like structure 112 of the first air-diffusing plate 110, such that the second air-diffusing plate 120 only rotates relative to the first air-diffusing plate 110, but the relative position between the second air-diffusing plate 120 as a whole and the first air-diffusing plate 110 is fixed.

[0109] Specifically, please refer to Figures 13 to 14 , in one embodiment, the plate-like structure 112 defines an installation groove 113 for rotatably installing the second air-diffusing plate 120; a buckle portion 122 that engages with the plate-like structure 112 protrudes from one side of the second air-diffusing plate 120, and the buckle portion 122 is used to prevent the second air-diffusing plate 120 from disengaging from the installation groove 113. The shape of the inner portion of the installation groove 113 matches the outer contour of the second air-diffusing plate 120. For example, when the second air-diffusing plate 120 is circular, the installation groove 113 is provided as a circular groove. The setting of the installation groove 113 can define the installation area of the second air-diffusing plate 120; the cooperation between the second air-diffusing plate 120 and the buckle portion 122 can be clamped and fixed on the opposite sides of the installation groove 113 of the plate-like structure 112, which helps with the detachable connection of the second air-diffusing plate 120 to the first air-diffusing plate 110.

[0110] In addition, please refer to Figure 15 , in one embodiment, a limiting post 114 protrudes from the side portion of the first air-diffusing plate 110, and a limiting groove is provided at the housing 101 corresponding to the limiting post 114. The limiting groove extends along the rotation direction of the first air-diffusing plate 110, and the limiting post 114 is slidably connected to the limiting groove in a matching manner. The limiting post 114 can be provided as one, or can be provided as a plurality of spaced-apart ones along the length direction of the first air-diffusing plate 110. Among them, when the limiting post 114 is provided as a plurality, the limiting groove is provided as a plurality corresponding to the plurality of limiting posts 114. The setting of the limiting post 114 and the limiting groove helps to improve the smoothness of the rotation of the first air-diffusing plate 110.

[0111] In addition, please refer to Figures 11 to 12 , in one embodiment, the air conditioner indoor unit 100 further includes a pivot structure provided between the connecting rod 130 and the louver 140. The pivot structure includes a convex shaft portion 141 and a groove portion 131 that are rotatably installed and matched; one of the convex shaft portion 141 and the groove portion 131 is provided on the connecting rod 130, and the other is provided on the louver 140. The setting of the convex shaft portion 141 and the groove portion 131 can achieve the limiting installation between the louver 140 and the connecting rod 130, and provide sufficient freedom required for the rotation of the louver 140.

[0112] Please refer to Figure 9 Figure 9 , in one embodiment, the connecting rod 130 is provided with the groove portion 131, and the connecting rod 130 is provided with a slotted opening 132 communicating with the groove portion 131 adjacent to the groove portion 131. There are at least two slotted openings 132, and the two slotted openings 132 are respectively arranged on opposite sides of the groove portion 131, so that when the convex shaft portion 141 is inserted into the groove portion 131, the area on the circumferential side of the groove portion 131 on the connecting rod 130 can undergo a certain deformation, which helps to stabilize the installation between the convex shaft portion 141 and the groove portion 131.

[0113] On the two air diffuser plates, the specific forms of the air diffuser openings can be various. It can be understood that different shapes and sizes of the air diffuser openings can cause corresponding changes in the air volume and air outlet effect, thus helping to enrich the air diffusing forms. Some of them will be listed and described below:

[0114] In one embodiment, the air diffuser openings are arranged in a grid shape or in a hole shape.

[0115] And further, the air diffuser plate includes a plurality of grid bars 116 forming the air diffuser openings, where: the plurality of grid bars 116 are arranged obliquely in the same direction relative to the plate surface of the air diffuser plate; or, the plurality of grid bars 116 are arranged bent in the same direction relative to the plate surface of the air diffuser plate; or, the plurality of grid bars 116 include a plurality of first grid bars and a plurality of second grid bars arranged in a cross shape.

[0116] Specifically, taking the first air diffuser plate 110 as being longitudinally long and the second air diffuser plate 120 as being circular as an example, it should be noted that the first air diffuser opening 111 and the second air diffuser opening 121 can be set to be the same or different:

[0117] First, please refer to Figure 16 Figure 16 , in one embodiment, the plurality of grid bars 116 on the first air diffuser plate 110 are arranged obliquely in the same direction relative to the plate surface of the first air diffuser plate 110, and the specific inclination direction and inclination angle can be set according to actual needs; each adjacent two grid bars 116 define a first air diffuser opening 111. The obliquely arranged grid bars 116 can strengthen the connection strength on the opposite sides of the first air diffuser plate 110 while forming the first air diffuser opening 111, acting as a reinforcing rib to ensure the structural strength of the first air diffuser plate 110. Please refer to Figure 22 Figure 22 , the principle of the second air diffuser plate 120 is the same as that of the above-mentioned first air diffuser plate 110, and will not be elaborated here.

[0118] Then, please refer to Figure 17, in one embodiment, a plurality of grille bars 116 are bent in the same direction relative to the plate surface of the first air diffusing plate 110; each two adjacent grille bars 116 define a first air diffusing opening 111. The grille bars 116 can be formed by bending once or multiple times, and the bending trends of all the grille bars 116 are substantially the same.

[0119] Then refer to Figure 18 , Figure 22 and Figure 23 , in one embodiment, a plurality of grille bars 116 include a plurality of first grille bars and a plurality of second grille bars arranged in a crosswise manner, and the plurality of first grille bars and the plurality of second grille bars jointly define a plurality of air diffusing openings distributed dispersedly. The plurality of first grille bars and the plurality of second grille bars increase the density of the plurality of air diffusing openings and can further enhance the structural strength of the air diffusing plate. There are various specific cross forms of the plurality of first grille bars and the plurality of second grille bars, which can be in a cross shape with each other or can be spliced with each other to form a spoke shape.

[0120] Please refer to Figure 19 and Figure 25 , in one embodiment, the air diffusing openings are arranged as hole-shaped structures penetrating through the thickness of the air diffusing plate, that is, air diffusing holes, and the plurality of air diffusing holes are distributed dispersedly on the plate surface of the air diffusing plate; and the specific shape and size of each air diffusing hole are not limited, which can be circular or square. The sizes of the plurality of air diffusing openings on the same air diffusing plate can be set to be the same or can be set to be at least partially different, and on a certain dimension line of the air diffusing plate, the sizes of the plurality of air diffusing openings are set to be gradually changed to form different air output amounts at each place. Please refer to Figure 25 , in which the grille bars 116 can be arranged as a whole from the center to the edge of the air diffusing plate or can be arranged in multiple pieces spliced in sequence.

[0121] In addition, please refer to Figure 20 , in one embodiment, the air diffusing plate includes a frame-shaped body 117 and a plurality of flow disturbing ribs 118 distributed dispersedly in the frame area of the frame-shaped body 117, and each two adjacent flow disturbing ribs 118 define the air diffusing openings. The plurality of flow disturbing ribs 118 are distributed dispersedly in the frame area, which helps to disperse the air flow blowing towards the flow disturbing ribs 118 to the periphery of the flow disturbing ribs 118 to form multiple air flows that do not interfere with each other.

[0122] The specific form of the flow disturbing ribs 118 is not limited. For example, it is set as a spherical shape, a hemispherical shape, a conical shape, a frustum shape, etc. Taking the spherical shape as an example, the outer surface of the flow disturbing rib 118 is arranged as an arc surface, which helps to smoothly guide the air flow and reduce the wind loss. At this time, the air flow passing through the plurality of flow disturbing ribs 118 forms a von Karman vortex street effect, so that it can be quickly dispersed and blown out.

[0123] Furthermore, adjacent spoiler ribs 118 are connected into an integral body through connecting arms 119, which can not only fix the spoiler ribs 118 relative to the frame-shaped body 117, but also form a mesh structure to enhance the overall strength of the air-diffusing plate and play a certain role in filtering impurities.

[0124] Next, please refer to Figure 21 , in one embodiment, the air-diffusing openings are arranged in a spiral shape extending on the plate surface of the air-diffusing plate. The specific spiral direction can be specifically adjusted according to actual needs. For example, when the air-diffusing plate is arranged in a longitudinal shape, the air-diffusing openings can extend spirally along the length direction of the air-diffusing plate.

[0125] Please refer to Figure 26 and Figure 27 , in one embodiment, from the center of the air-diffusing plate to the periphery of the air-diffusing plate is from the inside to the outside; a plurality of the air-diffusing openings are arranged radially on the air-diffusing plate. That is, each of the air-diffusing openings extends from the center of the air-diffusing plate towards the edge of the air-diffusing plate, and the plurality of air-diffusing openings are arranged at intervals along the circumferential direction of the air-diffusing plate.

[0126] Furthermore, in one embodiment, the plurality of air-diffusing openings are bent and extended gradually towards the same circumferential direction of the air-diffusing plate from the inside to the outside. Such a setting helps to form a longer air-diffusing opening on the limited plate surface of the air-diffusing plate and can guide the air flow towards the edge of the air-diffusing plate, which is helpful for the dispersion of the air flow.

[0127] Specifically, please refer to Figure 27 , each of the air-diffusing openings includes a plurality of ventilation holes 123 arranged at intervals, and the apertures of the plurality of ventilation holes 123 of each air-diffusing opening are gradually increased from the inside to the outside. It can be understood that the plurality of air-diffusing openings are arranged radially on the air-diffusing plate, and each air-diffusing opening is bent and extended gradually towards the same circumferential direction of the air-diffusing plate from the inside to the outside, that is, the plurality of ventilation holes 123 of each air-diffusing opening are arranged at intervals in the above linear shape. By adjusting the aperture of the ventilation holes 123, the ventilation volume and the specific air-diffusing effect formed can be specifically adjusted; by adjusting the number of the ventilation holes 123, the flow direction of the air-diffusing air flow can be adjusted to a certain extent. The apertures of the plurality of ventilation holes 123 of each air-diffusing opening are gradually increased from the inside to the outside, so that the air-diffusing effect formed on each air-diffusing plate from the inside to the outside has a gradual change effect, which is helpful for enriching the air-diffusing form.

[0128] Please refer to Figure 28, in one embodiment, the second air diffuser plate 120 includes a plurality of blades 124 arranged in a spoke-like manner, and the space between every two adjacent blades 124 forms the air outlet of the second air diffuser plate 120. Specifically, the specific form of the blade 124 may not be limited. For example, the width of each blade 124 may be set to gradually increase from the inside to the outside; each blade 124 may be set as a flat plate, or may be set to twist at a certain angle along the circumferential direction of the air diffuser plate to play a certain role in guiding air.

[0129] Or, please refer to Figure 29 , in one embodiment, the second air diffuser plate 120 includes a plurality of blades 124 arranged in a spoke-like manner, and each blade 124 is provided with a plurality of openings 125. The space between every two adjacent blades 124 and the plurality of openings 125 together form the air outlet of the second air diffuser plate 120. The setting of the blade 124 can refer to the above, and will not be elaborated here. It can be understood that by further opening openings 125 on the blade 124, the air passing area of the entire air diffuser plate is increased, which helps to improve the air diffusing effect.

[0130] Or, please refer to Figure 30 , in one embodiment, the second air outlet 121 extends in a vortex shape from the center of the second air diffuser plate 120 to the periphery of the second air diffuser plate 120. With this setting, uniform air outlet can be achieved in the entire circumferential direction of the second air diffuser plate 120. It should be noted that the "vortex shape" does not limit the shape of the vortex ring. The vortex ring can be set as a circular vortex ring or other shapes of vortex rings.

[0131] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
