Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] like Figures 1-4 As shown, the air-sweeping structure 1 according to an embodiment of the present invention includes: a bracket 10, a first fan assembly 20, a drive unit 30, and a transmission assembly 40.

[0032] Specifically, the first fan assembly 20 is rotatably mounted on the bracket 10, and the first fan assembly 20 defines a first air duct. The first fan 22 is fixedly mounted inside the first air duct. The transmission component 40 is rotatably mounted on the bracket 10 and is fixedly connected to the first fan assembly 20 to drive the first fan assembly 20 to rotate and change the air outlet direction of the first air duct. The drive unit 30 is mounted on the bracket 10 and is connected to the first fan assembly 20 to drive the transmission component 40 to rotate.

[0033] In detail, the first fan assembly 20 defines a first air duct, an air inlet, and an air outlet. The first air duct connects the air inlet and the air outlet. The first fan 22 drives airflow into the first air duct through the air inlet and out of the first air duct through the air outlet. The synchronous rotation of the first fan assembly 20 and the first fan 22 can change the air outlet direction, increase the sweeping range, and maintain the air velocity at the air outlet. This achieves a wide-range sweeping while ensuring the air delivery distance, thereby improving the efficiency of indoor temperature regulation. The first fan assembly 20 is rotatably mounted on the bracket 10 via a transmission component 40. The transmission component 40 is fixedly connected to the first fan assembly 20, and the connection between the transmission component 40 and the first fan assembly 20 can be detachable for easy assembly.

[0034] The drive unit 30 includes a motor and an electric motor. Figures 1-6 In the illustrated embodiment, the drive unit 30 is an electric motor. The drive unit 30 only needs to provide the power to rotate the first fan assembly 20. Those skilled in the art can flexibly select the appropriate type as needed, and this application does not impose excessive restrictions. When the drive unit 30 is an electric motor, the motor is fixed to the bracket 10 by a fixing frame 60.

[0035] According to the air-sweeping structure 1 of the present invention, the driving unit 30 can drive the first fan assembly 20 to rotate, and the first fan assembly 20 can drive the first fan 22 to rotate, thereby changing the air outlet direction of the first air duct, so that the first fan assembly 20 and the first fan 22 rotate synchronously, which can achieve large-scale air supply and improve the efficiency of indoor temperature regulation.

[0036] The first fan 22 includes either an axial flow fan or a mixed flow fan, which simplifies the structural design of the first air duct, avoids too many bends, and prevents the air velocity at the air outlet of the first fan assembly 20 from decreasing.

[0037] like Figures 1-4 As shown, the first fan 22 is an axial flow fan, the first air duct extends in a straight line, the axial direction of the axial flow fan is in the same direction as the extension direction of the first air duct, the air inlet and air outlet are arranged opposite to each other, and the air inlet and air outlet are located at both ends of the length direction of the first fan assembly 20, which avoids too many bends, resulting in higher air delivery efficiency and avoiding the possibility of reduced air velocity at the air outlet.

[0038] In addition, the first fan assembly 20 is located on the front side of the support 10, such as Figure 6 As shown, the support 10 is provided with a first guide hole 17, and the first guide hole 17 is along the thickness direction of the support 10 (e.g., Figure 1 and Figure 2 (As shown in the front and back direction) penetrating the bracket 10, the first guide hole 17 is set opposite to the air inlet hole. The first guide hole 17 is used to avoid the first fan assembly 20, so that the airflow can enter the first fan assembly 20 through the air inlet and the first guide hole 17.

[0039] In some embodiments, such as Figure 6 As shown, a limiting shaft 42 is fixed on the transmission component 40 and is disposed opposite to each other. A limiting hole is provided on the bracket 10. The limiting shaft 42 is rotatably inserted into the limiting hole. The two limiting shafts 42 are spaced apart along the first direction. The limiting shafts 42 extend along the first direction. The bracket 10 extends along the second direction. The first direction is perpendicular to the second direction.

[0040] Here, "first direction" is a defined direction, which can be up and down, left and right, or front and back, as shown in this application. Figure 8 In this context, the first direction is the left-right direction, but this application does not impose any restrictions and is merely illustrative.

[0041] "Second direction" is a defined direction, which can be up and down, left and right, or forward and backward, as shown in this application. Figure 1 and Figure 2 In this context, the second direction refers to the front-to-back direction, but this application does not impose any restrictions on it; it is merely an example.

[0042] exist Figure 6 In the embodiment shown, the bracket 10 is provided with a first pressure plate 14 and a second pressure plate 16. The first pressure plate 14 and the second pressure plate 16 are detachably connected to jointly define the limiting hole. During assembly, one of the first pressure plate 14 and the second pressure plate 16 can be fastened to the limiting shaft 42 first, and then fastened to the other, so as to facilitate the installation of the limiting shaft 42 into the limiting hole.

[0043] In some embodiments, the first direction is the left-right direction, and the two limiting shafts 42 include a first shaft and a second shaft arranged opposite to each other in the left-right direction. The first shaft and the second shaft extend in the left-right direction and are respectively located at both ends of the bracket 10. This makes the first fan assembly 20 more stable when rotating and prevents shaking.

[0044] like Figure 6 As shown, in some embodiments, the transmission member 40 is further provided with at least one set of connecting arms 44 arranged opposite to each other. The two sets of connecting arms 44 include a first connecting arm and a second connecting arm. The first connecting arms are arranged opposite to each other along a first direction, and the second connecting arms are arranged opposite to each other along a second direction. The two first connecting arms are respectively connected to the ends of the two limiting shafts 42 that are far apart from each other. The transmission member 40 is connected to the first fan assembly 20 through the connecting arms 44.

[0045] The first connecting arm is integrally formed with the corresponding limiting shaft 42, which simplifies the structural design and facilitates the assembly of the air-sweeping structure 1.

[0046] In some embodiments, a group of second connecting arms are arranged opposite each other in the vertical direction, and a group of first connecting arms are arranged opposite each other in the horizontal direction.

[0047] In some embodiments, such as Figure 2 and Figure 3 As shown, the transmission component 40 includes a rack 46, which is arc-shaped. The outer side of the arc of the rack 46 has meshing teeth. The drive unit 30 includes a motor connected to a first gear 32. The rack 46 meshes with the first gear 32 through the meshing teeth. Specifically, the motor is connected to the first gear 32 to drive the first gear 32 to rotate. The first gear 32 meshes with the rack 46 to drive the transmission component 40 to rotate. The rotation of the transmission component 40 drives the first fan assembly 20 to rotate. The transmission component 40 rotates about the central axis of the limiting shaft 42, and the rotation axis extends along a first direction, such as... Figure 8 As shown in the left and right directions, the transmission component 40 has a component that moves up and down in the vertical direction.

[0048] The air-sweeping structure 1 may also have at least one second gear. After the motor is reduced in speed by at least one second gear, it is connected to the first gear 32 to drive the first gear 32 to rotate. By controlling the forward and reverse rotation of the motor, the direction of rotation of the first gear 32 can be controlled, thereby controlling the rotation direction of the transmission component 40, and thus controlling the rotation direction of the first fan assembly 20.

[0049] In some embodiments, a first gear 32 is fitted onto the output shaft of the motor, and the axis of the output shaft of the motor extends along a first direction.

[0050] In some embodiments, such as Figure 6 and Figure 7 As shown, the first fan assembly 20 includes a first guide member 24 and a second guide member 26 connected to each other. The first guide member 24 and the second guide member 26 together define a first air duct. The first fan 22 is fixedly connected to the transmission member 40. The first guide member 24 is provided with at least one guide rib 242 along its circumference, and the second guide member 26 is provided with at least one guide groove 262 along its circumference. The guide groove 262 is engaged in the first guide member 24. The first guide member 24 and the second guide member 26 can guide the airflow, thereby increasing the air delivery distance of the first fan assembly 20. The cooperation of the guide rib 242 and the guide groove 262 facilitates the assembly of the second guide member 26 and the first guide member 24.

[0051] like Figure 7 As shown, the first guide member 24 and the second guide member 26 can be formed into a stepped cylindrical shape. The first guide member 24 and the second guide member 26 are connected in the air outlet direction of the first fan 22. This not only makes the overall structure of the first guide member 24 and the second guide member 26 simpler and more coordinated, but also reduces the airflow resistance due to the cylindrical structure, thereby improving the air outlet efficiency of the first fan assembly 20. Of course, the first guide member 24 and the second guide member 26 can also be set into other closed-loop cylindrical structures, which can be selected according to actual usage requirements. This application does not impose specific limitations.

[0052] In some embodiments, the first guide member 24 is connected to the connecting arm 44, and the second guide member 26 is disposed on the side of the first guide member 24 away from the transmission member 40. The end of the second guide member 26 away from the first guide member 24 defines an air duct, and the air duct is covered by an air guide grille 264, which defines a plurality of sub-air outlets. In this way, the airflow flowing out of the first fan assembly 20 can be dispersed by the air guide grille 264, thereby achieving a windless airflow effect and improving user comfort.

[0053] The first guide component 24 and the second guide component 26 are designed as separate parts, which simplifies the processing steps of the first guide component 24 and the second guide component 26. At the same time, during assembly, the first guide component 24 can be adjusted and assembled with the transmission component 40 first. Since both ends of the first guide component 24 are open, it is convenient to observe the distance between the first guide component 24 and the first fan 22. It is also convenient to fix the first guide component 24 and the transmission component 40 with fasteners. After the first guide component 24 is positioned and assembled, the second guide component 26 is assembled with the first guide component 24. This allows the first guide component 24 and the second guide component 26 to be better assembled and prevents interference with the fan blades 224 of the first fan 22.

[0054] In some embodiments, such as Figure 5 and Figure 6 As shown, the first fan 22 includes a power unit 222 and a fan blade 224. The power unit 222 is connected to the fan blade 224 to drive the fan blade 224 to rotate. When assembling the sweeping structure 1, the fixing frame 60 is installed on the bracket 10, and then the motor and the first gear 32 are installed in place. The first pressure plate 14, the transmission component 40, and the second pressure plate 16 are installed on the bracket 10 so that the first gear 32 meshes with the rack 46 on the transmission component 40. The power unit 222 and the fan blade 224 are fixed to the transmission component 40 by a snap pin. The two sets of connecting arms 44 of the transmission component 40 are assembled and fixed to the corresponding positions of the first guide component 24. Finally, the guide groove 262 of the second guide component 26 is aligned with the guide rib 242 on the first guide component 24, and the second guide component 26 is fitted onto the first guide component 24 to complete the assembly.

[0055] According to the sweeping structure 1 of the present invention, as shown in the embodiment of the present invention, Figure 6 As shown, the bracket 10 is provided with a baffle 12, which is located below the first fan assembly 20. The first fan assembly 20 has a first position and a second position. The first fan assembly 20 can rotate between the first position and the second position. When the first fan assembly 20 is in the first position, it is spaced apart from the baffle 12. When the first fan assembly 20 is in the second position, it abuts against the baffle 12.

[0056] When the air-sweeping structure 1 is in operation, the movement component of the first fan assembly 20 can be controlled to move vertically from top to bottom, or it can be controlled to move vertically from bottom to top. In other words, the first fan assembly 20 can be controlled to rotate from a first position to a second position, or from a second position to a first position, or to rotate back and forth between the first and second positions, or to rotate at a certain angle and then remain in a third position between the first and second positions.

[0057] Among them, "first position", "second position" and "third position" are all defined positions, which are only used to distinguish the relative positional relationship between the first fan assembly 20 and the support 10. The third position is any position between the first position and the second position, and is not limited to a certain fixed position.

[0058] For example, in an embodiment of this application, Figure 1 This diagram shows the first fan assembly 20 in the first position. Figure 2 A schematic diagram showing the first fan assembly 20 in the second position is shown. Figure 3 A schematic diagram of the first fan assembly 20 in the third position is shown. The air-sweeping structure 1 is applied in the air conditioner 100. In the vertical direction, the first position can be a position where the air outlet direction of the first fan 22 is diagonally upward, and the second position can be a position where the air outlet direction of the first fan 22 is diagonally downward. Thus, when the first fan assembly 20 abuts against the baffle 12, the motor senses this and pauses operation or changes direction, driving the first fan assembly 20 to rotate towards the first position. The transmission member 40 is provided with a stop portion, which is arranged side-by-side with the rack 46 and located at the end of the rack 46 furthest from the first fan assembly 20. When the first fan assembly 20 rotates to the first position, the first gear 32 abuts against the stop portion. This prevents the first gear 32 from disengaging from the rack 46. Furthermore, when the motor senses that the first fan assembly 20 has moved into position, it pauses operation or changes direction, driving the first fan assembly 20 to rotate towards the second position.

[0059] In some embodiments, when the first fan assembly 20 is in the third position, the air outlet direction of the first fan 22 is perpendicular to the vertical direction. The angle through which the first fan assembly 20 rotates from the third position to the first position is the same as the angle through which the first fan assembly 20 rotates from the third position to the second position. This simplifies the structural setup. At the same time, when the air-sweeping structure 1 is applied in the air conditioner 100, the initial position of the air-sweeping structure 1 is the third position, which facilitates packaging and transportation.

[0060] In some embodiments, such as Figure 5 As shown, the bracket 10 is also provided with a second fan assembly 50, which is spaced apart from the first fan assembly 20. The baffle 12 is located between the first fan assembly 20 and the second fan assembly 50. The second fan assembly 50 includes a second fan.

[0061] It should be noted that the second fan includes either an axial flow fan or a mixed flow fan. Thus, through the above arrangement, the first fan assembly 20 and the second fan assembly 50 can simultaneously deliver air, thereby improving the air delivery efficiency of the sweeping structure 1.

[0062] The second fan assembly 50 may further include a third guide member and a second motor bracket. The third guide member can be connected to the bracket 10 and spaced apart from the first guide member 24. The second motor bracket can be connected to the third guide member. The second fan can be mounted on the second motor bracket and located inside the third guide member. The third guide member can be integrally formed with the bracket 10, which simplifies the overall structure of the swept air structure 1 and improves the assembly efficiency of the swept air structure 1.

[0063] It is understandable that the third guide component can also be configured as a separate component from the bracket 10, with the second fan assembly 50 located on the front side of the bracket 10, such as... Figure 5 As shown, the bracket 10 is provided with a second guide hole 18. The second guide hole 18 penetrates the bracket 10 along the thickness direction (the front and back direction shown in the figure). The second guide hole 18 is arranged opposite to the air inlet. The second guide hole 18 is used to avoid the second fan assembly 50, so that the airflow can enter the second fan assembly 50 through the air inlet and the second guide hole 18.

[0064] It should also be noted that the air-sweeping structure 1 may have one second fan assembly 50 or at least two second fan assemblies 50, which can be selected according to actual usage requirements. This application does not impose any restrictions.

[0065] It is understandable that the operating states of the first fan assembly 20 and the second fan assembly 50 can be controlled independently. For example, the swing structure 1 can be installed in the air conditioner 100, and the second fan assembly 50 is located below the first fan assembly 20. When the air conditioner 100 is in heating mode, because the air density of hot air is low and its circulation speed is slow, the first fan assembly 20 and the second fan assembly 50 can be controlled to work simultaneously. At the same time, the first fan assembly 20 can rotate to increase the swing range, thereby improving the air outlet efficiency of the swing structure 1. Hot air can circulate quickly in the indoor space, improving the heating efficiency of the air conditioner 100.

[0066] In a specific example of this application, the second fan can be a diagonal-flow fan, which can discharge air diagonally downwards from the air conditioner 100. When the air conditioner 100 is in heating mode, the second fan can be controlled to work independently, and hot air can quickly flow to the lower part of the indoor space, thereby warming the feet and greatly improving the user's comfort.

[0067] When the air conditioner 100 is cooling, the first fan 22 and the second fan can be controlled to work simultaneously. In order to prevent cold air from blowing directly on the user, the first fan assembly 20 can be controlled to rotate towards the corner of the space to disperse the air, thereby improving the cooling effect of the air conditioner 100. At the same time, when the first fan assembly 20 discharges air diagonally downwards, the airflow discharged by the second fan assembly 50 collides with the airflow discharged by the first fan assembly 20 in front of the sweeping structure 1. After the airflow collides, it can be dispersed in all directions, and the cold air can circulate in multiple directions in the indoor space. This can prevent the cold air from blowing directly on the user and causing discomfort, and can achieve a windless air outlet effect, improving the user's comfort.

[0068] The following is for reference. Figure 8 An air conditioner 100 according to an embodiment of the present invention is described, which can cool and heat indoor air.

[0069] An air conditioner 100 according to an embodiment of the present invention includes: a housing 1001, on which an air outlet and an air inlet are provided, and an airflow channel communicating with the air inlet and the air outlet is also provided inside the housing 1001; a sweeping structure 1 as described above, the sweeping structure 1 is disposed in the airflow channel, and the first fan assembly 20 of the sweeping structure 1 is disposed opposite to the air outlet.

[0070] Specifically, such as Figure 5 As shown, a heat exchange component 70 can also be installed inside the air conditioner 100, and the heat exchange component 70 is located in the airflow channel. When the air conditioner 100 starts to work, the first fan component 20 of the air sweeping structure 1 can operate to guide the airflow through the air inlet into the airflow channel to exchange heat with the heat exchange component 70. The airflow that has completed heat exchange can be discharged into the room through the air outlet, thereby achieving the purpose of regulating the indoor temperature.

[0071] According to an embodiment of the present invention, the air conditioner 100 has a drive unit 30 of the air sweeping structure 1 that can drive the first fan assembly 20 to rotate, and the first fan assembly 20 can drive the first fan 22 to rotate, thereby changing the air outlet direction of the first air duct, so that the first fan assembly 20 and the first fan 22 rotate synchronously, which can achieve a wide range of air supply and improve the efficiency of indoor temperature regulation.

[0072] like Figure 8 As shown, in an air conditioner 100 according to an embodiment of the present invention, the housing 1001 is provided with an air outlet grille 1002 spaced apart from the air outlet, and the air sweeping structure 1 is provided with a guide grille 264 at one end near the air outlet grille 1002, the guide grille 264 being spaced apart from the air outlet grille 1002.

[0073] According to the embodiment of the present invention, the air outlet grille 1002 can prevent pollutants in the air from entering the casing 1001 and prevent organisms from entering, thus providing isolation and protection for the air conditioner 100 and organisms. The air guide grille 264 is spaced apart from the air outlet grille 1002 to prevent interference between the first fan assembly 20 and the air outlet grille 1002 when the fan assembly 20 rotates.

[0074] In some embodiments, the housing 1001 includes a panel component and a back panel component. The panel component is located on the front side of the back panel component and cooperates with the back panel component to jointly define a receiving cavity. The receiving cavity is provided with a sweeping structure 1 and a heat exchange assembly 70. The sweeping structure 1 includes a first fan assembly 20 and a second fan assembly 50 located below the first fan assembly 20. The panel component is provided with two air outlets spaced apart in the vertical direction. Each air outlet is provided with an air outlet grille 1002. The first fan assembly 20, the upper air outlet, and the air outlet grille 1002 are arranged facing each other in the direction from back to front.
