[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0045] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0046] The present invention provides a wind sweeping mechanism, please refer to Figures 1 to 16 , including: an air outlet frame 10, having an air outlet 11; a driving assembly 20; a first air sweeping assembly 30, including a first air sweeping blade 31, a first transmission structure 32 and a second transmission structure 33, the driving assembly 20 is connected to a first end of the first transmission structure 32, so that the first transmission structure 32 is rotatably arranged around the axis of the output shaft of the driving assembly 20, and the second end of the first transmission structure 32 is rotatably connected to the first end of the first air sweeping blade 31; the first end of the second transmission structure 33 is rotatably connected to the air outlet frame 10, and the second end of the second transmission structure 33 is rotatably connected to the second end of the first air sweeping blade 31.

[0047] The first air sweeping assembly 30 of the air sweeping mechanism of the present invention is connected to the air outlet frame 10 and is used to sweep and guide the air out of the air outlet 11. Figure 1As shown, when the driving component 20 drives the first transmission structure 32 to rotate, and the first transmission structure 32 drives the first wind sweeping blade 31 to move, the first wind sweeping blade 31 and the second transmission structure 33 rotate relative to each other, and at the same time, the second transmission structure 33 and the air outlet frame 10 are also driven to rotate relative to each other, so as to realize the opening, closing and wind sweeping of the first wind sweeping blade 31; the wind sweeping mechanism makes the angle and position of the first wind sweeping blade 31 more adjustable through the relative rotation between the first wind sweeping blade 31, the first transmission structure 32 and the second transmission structure 33, thereby increasing the movement range of the first wind sweeping blade 31 and realizing a wide range of wind sweeping.

[0048] In this embodiment, the first transmission structure 32 includes two first connecting rods 321, the two first connecting rods 321 are arranged on opposite sides of the first wind sweeping blade 31, and the second end of each first connecting rod 321 is hinged to the first end of the first wind sweeping blade 31; the driving assembly 20 includes a driving member 21, the first end of one of the two first connecting rods 321 is connected to the driving member 21, and the first end of the other of the two first connecting rods 321 is rotatably connected to the air outlet frame 10; or, the driving assembly 20 includes two driving members 21, the two driving members 21 are arranged in a one-to-one correspondence with the two first connecting rods 321, and each driving member 21 is connected to the first end of the corresponding first connecting rod 321. Specifically, when the driving assembly 20 includes two driving members 21, the two driving members 21 move synchronously to ensure that the two first connecting rods 321 move synchronously.

[0049] Optionally, the driving member 21 is a motor.

[0050] In this embodiment, the second transmission structure 33 includes two second connecting rods 331, and the two second connecting rods 331 are arranged on opposite sides of the first wind sweeping blade 31; the first end of each second connecting rod 331 is hinged to the air outlet frame 10, and the second end of each second connecting rod 331 is hinged to the second end of the first wind sweeping blade 31.

[0051] In this embodiment, the second transmission structure 33 further includes a third connecting rod 334, a first end of the third connecting rod 334 is fixedly connected to one of the two second connecting rods 331, and a second end of the third connecting rod 334 is fixedly connected to the other of the two second connecting rods 331. The provision of the third connecting rod 334 enables the two second connecting rods 331 to move as a whole, thereby preventing the two second connecting rods 331 from moving asynchronously.

[0052] Optionally, the two second connecting rods 331 and the third connecting rod 334 are integrally formed.

[0053] In this embodiment, there are multiple first air sweeping components 30, and the multiple first air sweeping components 30 are arranged at intervals on the air outlet frame 10; there are multiple drive components 20, and the multiple drive components 20 are arranged one-to-one with the multiple first air sweeping components 30, and each drive component 20 is connected to the first transmission structure 32 of the corresponding first air sweeping component 30. Such an arrangement allows each first air sweeping blade 31 to have a larger range of motion.

[0054] In the present embodiment, the output end of the driving component 20 is rotatably arranged along the first rotation direction and the second rotation direction; wherein the first rotation direction is opposite to the second rotation direction; the first wind sweeping blade 31 has a first end face 311 and a second end face 312 arranged opposite to each other, and the first wind sweeping blade 31 has a first wind sweeping position in which the air outlet 11 is opened and the first end face 311 is the windward side, a second wind sweeping position in which the air outlet 11 is opened and the second end face 312 is the windward side, and a closed position in which the air outlet 11 is closed and the first end face 311 is arranged toward the external environment; the first wind sweeping blade 31 is movably arranged between the first wind sweeping position and the closed position, and the second wind sweeping position is located between the first wind sweeping position and the closed position.

[0055] In this embodiment, when the first air sweeping blades 31 are in the closed position, the ends of two adjacent first air sweeping blades 31 abut against each other.

[0056] In specific implementation, the first rotation direction is Figure 4 and Figure 5 The counterclockwise rotation direction in the second rotation direction is Figure 4 and Figure 5 In the clockwise rotation direction, when the first air sweeping blade moves from the closed position to the first air sweeping position, the output shaft rotates counterclockwise, and when the first air sweeping blade moves from the first air sweeping position to the closed position, the output shaft rotates clockwise. Figure 4 The first sweeping blade 31 is in the first sweeping position. When the wind in the cabinet is blown upward, the wind direction is as follows: Figure 4 In the x direction, the first wind sweeping blade 31 guides the wind forward through the first end face 311 (the forward wind guiding here refers to the wind guiding in the left direction in the figure). At this time, when the output shaft rotates alternately in the first rotation direction and the second rotation direction, upward and downward wind sweeping can be achieved, and the second wind sweeping component can sweep the wind left and right, thereby achieving large-angle air supply. Figure 5 The first wind sweeping blade 31 is in the closed position (the first wind sweeping blade 31, the first transmission structure and the second transmission structure are in the folded state). When the output shaft rotates clockwise, the wind sweeping blade can reach the closed position from the first wind sweeping position. At this time, it is equivalent to the first wind sweeping blade being reversed, and the first end surface 311 is set toward the external environment. In addition, when the first wind sweeping blade 31 is in the closed position, the air outlet is closed by the end of the first wind sweeping blade being fitted ( Figure 5It is a schematic diagram. In practice, the seal in the closed state can be made more compact by adjusting the structural dimensions of the first air sweeping component).

[0057] In a specific implementation, the second sweeping position is an intermediate position between the first sweeping position and the closed position. In the process of the first sweeping blade moving from the first sweeping position to the closed position, the first sweeping blade can reach the closed position only after passing through the second sweeping position. Figure 6 As shown, at this time, the second end surface is the windward side, and the second end surface guides the wind.

[0058] In this embodiment, if Figure 6 , Figure 7 and Fig.12 As shown, a plurality of air supply holes 313 are arranged at intervals on the first sweeping blade 31 . The air supply holes 313 are tapered holes, the small diameter end of the tapered hole is located at the first end surface 311 , and the large diameter end of the tapered hole is located at the second end surface 312 .

[0059] When implementing it specifically, Figure 6 and Figure 7 The first air sweeping blade 31 is a form of the first air sweeping blade 31, which is provided with micro holes (i.e., air supply holes 313). Figure 6 It is a micro-pore air outlet mode. At this time, the first air sweeping blade 31 is in the second air sweeping position, the small diameter end of the tapered hole is facing forward (that is, the small diameter end of the tapered hole is located on the leeward side), and the large diameter end of the tapered hole is facing backward (that is, the large diameter end of the tapered hole is located on the windward side), so that the micro-pores can be discharged forward. When the first air sweeping blade 31 is in the first air outlet position, the first air sweeping blade 31 is in the normal air outlet mode, and the first end face of the first air sweeping blade 31 guides the wind forward. Because the small diameter end of the tapered hole is facing the wind side, the amount of air flowing into the hole will be relatively small. It can be seen that the micro-pore air outlet and the overall air guide are achieved by providing the first air sweeping blade 31 with the air supply through hole 313.

[0060] It should be noted that when the first sweeping blade 31 is in the micro-hole air outlet mode, part of the air conditioning air is blown forward through the large diameter end and the small diameter end of the air supply through hole 313 in sequence, and part is blown upward through the gap between two adjacent first sweeping blades 31. The micro-hole air outlet mode can ensure that the air conditioning outlet is gentle and avoids user discomfort. When the first sweeping blade 31 is in the normal air outlet mode, that is, when the first sweeping blade 31 guides the air as a whole, it can ensure that the air conditioning outlet has a large air volume, quickly realize the temperature change of the indoor air, and have high cooling and heating efficiency.

[0061] In another embodiment, there are multiple first air sweeping components 30, and the multiple first air sweeping components 30 are arranged at intervals on the air outlet frame 10; there is one driving component 20, and the driving component 20 is connected to the first transmission structure 32 of one of the multiple first air sweeping components 30; wherein the air sweeping mechanism further includes a connecting rod, and the connecting rod is connected to the first transmission structures 32 of the multiple first air sweeping components 30. Such a setting can realize the synchronous movement of multiple first air sweeping components through the connecting rod, reduce the use of motors, and reduce production costs.

[0062] In another embodiment, Figure 6 and Figure 8 As shown, the second transmission structure 33 further includes an air guide plate 332 for guiding wind, the first end of the air guide plate 332 is connected to one of the two second connecting rods 331, and the second end of the air guide plate 332 is connected to the other of the two second connecting rods 331. In specific implementation, during the movement of the first air sweeping component, the angle between the second transmission structure 33 and the first air sweeping blade will change, and then the air guide plate 332 will be inclined or flush with the first air sweeping blade, so that a larger air guide angle can be achieved, or the wind can be directed farther.

[0063] In another embodiment, Figure 8 As shown, the second transmission structure 33 further includes an air supply grille 333, a first end of the air supply grille 333 is connected to one of the two second connecting rods 331, and a second end of the air supply grille 333 is connected to the other of the two second connecting rods 331. The use of this grille structure can improve the angle and effect of air supply and achieve better compressed air sweeping effect.

[0064] In this embodiment, the first sweeping blade 31 is an arc plate or a flat plate. The first sweeping blade 31 is an arc plate so that the air outlet direction and the appearance effect can be adjusted.

[0065] In this embodiment, if Figure 1 As shown, the first wind sweeping component 30 is used for sweeping air up and down, and the wind sweeping mechanism also includes a second wind sweeping component 50 for sweeping air left and right. The second wind sweeping component 50 is arranged on a side of the first wind sweeping component 30 away from the external environment.

[0066] In this embodiment, the air sweeping mechanism is arranged at the top of the air conditioner indoor unit, and the air outlet is located at the top of the air sweeping structure; the top surface of the air sweeping mechanism is inclined relative to the horizontal plane, and such a setting can be coordinated with the first air sweeping component to realize forward air supply of the air conditioner indoor unit.

[0067] In this embodiment, the air sweeping mechanism further includes a decorative ring 60, and the decorative ring 60 is arranged around the air outlet frame 10. Such an arrangement makes the appearance of the air sweeping mechanism more beautiful.

[0068] Specifically, the air outlet frame 10 is a frame structure, and the first transmission structure and the second transmission structure are assembled on both sides of the frame structure, and one or more first air sweeping components can be assembled; wherein, the driving member 21 is installed on the air outlet frame 10 and is located on the outside of the air outlet frame 10.

[0069] Specifically, a first connecting column 314 is disposed at the first end of the first wind sweeping blade 31 , a first connecting hole is disposed on the first connecting rod 321 , and the first connecting column 314 is inserted into the connecting hole and is rotatably disposed relative to the first connecting rod 321 .

[0070] Specifically, a connecting portion 315 is provided at the second end of the first sweeping blade 31 , and a second connecting hole 316 is provided on the connecting portion 315 ; a second connecting column 335 is provided on the second connecting rod 331 ; the second connecting column 335 is inserted into the second connecting hole 316 and is rotatably provided relative to the first sweeping blade 31 .

[0071] Preferably, a notch 317 is provided on the connecting portion 315, and the second connecting rod 331 is clamped in the second connecting hole 316 of the connecting portion 315 through the notch 317. Such a configuration facilitates the installation of the second connecting rod 331 and the first sweeping blade 31.

[0072] The invention further provides an air conditioner indoor unit, comprising an air sweeping mechanism, wherein the air sweeping mechanism is the air sweeping mechanism in the above embodiment.

[0073] Specifically, the indoor unit of the air conditioner is a cabinet unit with upper and lower air outlets, and the air sweeping mechanism is assembled at the head of the cabinet unit to realize upper air outlet.

[0074] The present invention solves the following technical problems: the air outlet and sweeping mechanism on the air conditioner cabinet is complicated, the assembly efficiency is low and the cost is high; the air supply angle of the sweeping mechanism is small and the air supply range is greatly limited; the sweeping mechanism has poor sweeping and air pressure effects; the sweeping blades have a single movement form, poor appearance effect and single function.

[0075] Beneficial effects of the present invention: Due to the combination of the foldable form of the wind sweeping mechanism, the first transmission structure, the second transmission structure, the air outlet frame, and the first wind sweeping blade of the present application, the wind sweeping mechanism has high assembly efficiency, few parts, and low cost. Due to the foldable form of the wind sweeping mechanism of the present application, there can be a variety of wind outlet forms during the movement of the wind sweeping mechanism. Due to the foldable form of the wind sweeping mechanism of the present application, the wind sweeping blade is different from the previous opening method of the "open mouth" form during the opening process, so that the appearance effect is better when opened; due to the use of the foldable form of the wind sweeping mechanism of the present application, the sealing effect is better when closed, and a better sealing effect can be achieved. Due to the use of the foldable form of the wind sweeping mechanism of the present application, the first wind sweeping blade can adopt different curvatures to achieve a better wind-guiding and wind-sweeping effect. Due to the use of the foldable form of the wind sweeping mechanism of the present application, the second transmission structure can be transformed into various forms, such as adding a guide grille, etc., so that the functional expandability is enhanced. Among them, the foldable form refers to the first wind-sweeping blade moving from the first wind-sweeping position to the closed position, and the positional relationship between the first transmission structure and the second transmission structure. When the first wind-sweeping blade is in the closed position, the first wind-sweeping blade and the first transmission structure and the second transmission structure are all in a folded state or a state close to being folded.

[0076] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0077] The first air sweeping assembly 30 of the air sweeping mechanism of the present invention is connected to the air outlet frame 10 and is used to sweep and guide the air out of the air outlet 11. Figure 1 As shown, when the driving component 20 drives the first transmission structure 32 to rotate, and the first transmission structure 32 drives the first wind sweeping blade 31 to move, the first wind sweeping blade 31 and the second transmission structure 33 rotate relative to each other, and at the same time, the second transmission structure 33 and the air outlet frame 10 are also driven to rotate relative to each other, so as to realize the opening, closing and wind sweeping of the first wind sweeping blade 31; the wind sweeping mechanism makes the angle and position of the first wind sweeping blade 31 more adjustable through the relative rotation between the first wind sweeping blade 31, the first transmission structure 32 and the second transmission structure 33, thereby increasing the movement range of the first wind sweeping blade 31 and realizing a wide range of wind sweeping.
