Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and in particular to a swing device, an air conditioner and a control method thereof. Background Technology

[0002] Air conditioning is an almost indispensable household appliance in modern life. It not only controls ambient temperature but also offers a variety of other functions, one of which is controllable airflow direction. Currently, the most common airflow direction is four-way swing, meaning it can move in four directions: up, down, left, and right. Vertically rotating air deflectors control the vertical airflow, while horizontally rotating air blades control the horizontal airflow.

[0003] Among them, the sweeping blades at the air outlet of the air conditioner guide the airflow direction but also block some of the air volume. Especially in the soft wind mode that has appeared on the market, after passing through the air baffle with a microporous structure in the air conditioner, the airflow speed and flow rate that the user comes into contact with is slow and small. At this time, the air sweeping blades significantly reduce the air outlet speed and air volume of the air conditioner, shorten the normal air supply distance of the air conditioner, and affect the performance of the air conditioner. Summary of the Invention

[0004] This application provides a sweeping device, an air conditioner, and a control method thereof to solve the problem that the sweeping blades reduce the airflow speed and volume of the air conditioner when they are not in use.

[0005] In a first aspect, this application provides a wind sweeping device, comprising:

[0006] The housing has an air outlet and multiple spaced-apart air slots on its surface; and

[0007] The air-sweeping mechanism is disposed within the housing;

[0008] The air sweeping mechanism includes:

[0009] The movable component has multiple sweeping blades spaced apart on it, and each of the sweeping slots corresponds one-to-one with each of the sweeping blades; and

[0010] The driver drives the movable part to move through the first transmission component, so that the sweeping blade is housed in the sweeping groove or the sweeping blade is located outside the sweeping groove and at the air outlet; the driver drives each of the sweeping blades to swing back and forth through the second transmission component.

[0011] In one possible implementation, the second transmission assembly includes a reciprocating pusher connected to one of the sweeping blades, and the sweeping blades are interconnected by connectors.

[0012] In one possible implementation, the connector includes a connecting body and a plurality of snap-fit ​​parts spaced apart on the connecting body. Each of the sweeping blades is provided with a snap-fit ​​portion that can be detachably engaged with the snap-fit ​​part, and each snap-fit ​​portion corresponds to each snap-fit ​​part.

[0013] In one possible implementation, the pushing member and the sweeping blade connected to it move in coordination with each other along the direction of movement of the moving member.

[0014] In one possible implementation, a drive shaft is rotatably connected to the driver, the first transmission assembly includes a first driven shaft and a first transmission shaft, the first driven shaft and the first transmission shaft are connected and disconnected by a first switch, the first driven shaft is connected to the drive shaft, and the first driven shaft is connected to the moving part.

[0015] In one possible implementation, the second transmission assembly includes a second driven shaft and a second transmission shaft, the second driven shaft and the second transmission shaft being connected and disconnected by a second switch, the second driven shaft being connected to the drive shaft, and the second transmission shaft driving the oscillation of the pusher through a crank-rocker assembly.

[0016] In one possible implementation, the crank rocker assembly includes a first connecting rod connected to the second drive shaft, an end of the first connecting rod being connected to a second connecting rod via a slider, the slider being in sliding engagement with the second connecting rod, one end of the second connecting rod being hinged to the housing, and the other end of the second connecting rod being hinged to the pusher via a third connecting rod.

[0017] In one possible implementation, a first driving gear and a second driving gear are spaced apart on the driving shaft, a first driven gear is provided on the first driven shaft and meshes with the first driving gear, and a second driven gear is provided on the second driven shaft and meshes with the second driving gear.

[0018] Secondly, this application provides an air conditioner including the air-sweeping device as described in the first aspect.

[0019] Thirdly, this application provides a method for controlling an air conditioner, used to control the air conditioner of the second aspect, the method comprising:

[0020] When the blades are in the hidden state, the actuator controls the sweeping blades to move from the air outlet to the sweeping slot;

[0021] In the air-sweeping state, the position of the air-sweeping blades is detected. If the air-sweeping blades are located in the air-sweeping groove, the driver is controlled to drive the air-sweeping blades to move from the air-sweeping groove to the air outlet. If the air-sweeping blades are located at the air outlet, the driver controls each air-sweeping blade to swing back and forth.

[0022] The technical solutions provided in this application have the following advantages compared with the prior art:

[0023] The air-sweeping device, air conditioner, and control method provided in this embodiment involve a driver that moves a movable component, which in turn moves the sweeping blades located thereon synchronously. When the sweeping blades move into the sweeping slot, they open the air outlet of the housing, preventing them from blocking the outlet and affecting the air velocity and volume when not in use. When the sweeping blades need to operate, the driver moves the movable component, which in turn moves the sweeping blades located thereon synchronously, moving them from the sweeping slot to the outlet. The driver then drives each sweeping blade to oscillate back and forth via a second transmission component, thereby achieving oscillating air delivery. Therefore, the air-sweeping device provided in this embodiment not only ensures the oscillating air delivery effect of the sweeping blades but also allows the sweeping blades to be removed from the outlet and hidden when not in use, ensuring that they do not affect the air velocity and volume at the outlet. Compared to removing the sweeping blades from the housing when they are not needed, the solution provided in this application is easier to operate, reduces labor costs, and improves work efficiency.

[0045] 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.

[0046] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0047] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0048] Reference Figures 1-10 This application provides a wind sweeping device, including:

[0049] Housing 1, the housing 1 having an air outlet 101, and the housing 1 having a plurality of spaced-apart sweeping grooves 102; and

[0050] The air-sweeping mechanism is disposed within the housing 1;

[0051] The air sweeping mechanism includes:

[0052] The movable component 2 has multiple sweeping blades 3 spaced apart thereon, and each of the sweeping slots 102 corresponds one-to-one with each of the sweeping blades 3; and

[0053] The driver 4 drives the movable part 2 to move through the first transmission component 5, so that the sweeping blade 3 is housed in the sweeping groove 102 or the sweeping blade 3 is located outside the sweeping groove 102 and at the air outlet 101; the driver 4 drives each of the sweeping blades 3 to swing back and forth through the second transmission component 6.

[0054] The driver 4 drives the movable part 2 to move, and the movable part 2 drives the sweeping blades 3 located on it to move synchronously. When the sweeping blades 3 move into the sweeping groove 102, the sweeping blades 3 open the air outlet 101 of the housing 1, so that when the sweeping blades 3 do not need to work, they will not block the air outlet 101 and affect the air speed and air volume of the air outlet 101. When the sweeping blades 3 need to work, the driver 4 drives the movable part 2 to move, and the movable part 2 drives the sweeping blades 3 located on it to move synchronously, so that the sweeping blades 3 move from the sweeping groove 102 to the air outlet 101. Then the driver 4 drives each sweeping blade 3 to swing back and forth through the second transmission component 6, thereby realizing swing air delivery. Therefore, the air-sweeping device provided in this application embodiment can not only ensure the air-blowing effect of the sweeping blades 3, but also remove the sweeping blades 3 from the air outlet 101 and hide them when they are not needed, so that the sweeping blades 3 will not affect the air velocity and air volume at the outlet. Compared with the method of removing the sweeping blades 3 from the housing 1 when they are not needed, the solution provided in this application is easier to operate, reduces labor costs, and improves work efficiency.

[0055] The movement of the sweeping blade 3 into the sweeping groove 102 can be either linear or rotary. When the sweeping blade 3 moves linearly, the driver 4 drives the movable part 2 to move in a linear direction, thereby moving the sweeping blade 3 into the sweeping groove 102 under the action of the movable part 2. In this case, the driver 4 can be a component such as a cylinder, an electric push rod, or a combination of a motor and a lead screw to drive the movable part 2 to move in a linear direction. When the sweeping blade 3 moves rotaryly, the driver 4 drives the movable part 2 to rotate, and the movable part 2 drives the sweeping blade 3 to rotate synchronously, thereby moving into the sweeping groove 102. In this case, the driver 4 can be a motor or a rotary cylinder. In order to reduce the movement trajectory of the sweeping blade 3 and ensure the overall miniaturization of the device, the movement of the sweeping blade 3 into the sweeping groove 102 in this application adopts rotary motion. Specifically, the driver 4 is a drive motor, which is mounted on the housing 1. The drive motor drives the rotation of the movable part 2, thereby driving the sweeping blade 3 to rotate synchronously.

[0056] In some embodiments, the second transmission component 6 includes a reciprocating pusher 61, which is connected to one of the sweeping blades 3. The sweeping blades 3 are interconnected by a connector 7. Since one end of the sweeping blade 3 is connected to the movable component 2, the reciprocating motion of the pusher 61 pushes the sweeping blade 3 connected to it to swing back and forth around the end connected to the movable component 2. Under the action of the connector 7 connecting the sweeping blades 3, the swing of one sweeping blade 3 will drive the remaining sweeping blades 3 to swing synchronously through the connector 7. The sweeping blades 3 achieve the effect of swinging air delivery by swinging.

[0057] To ensure that the sweeping blade 3 can swing back and forth under force, the sweeping blade 3 is made of a material with a certain degree of deformation. Optionally, the sweeping blade 3 is a plastic part with a certain degree of elasticity.

[0058] Specifically, the connector 7 includes a connecting body 71 and a plurality of snap-fit ​​parts 72 spaced apart on the connecting body 71. Each of the sweeping blades 3 is provided with a snap-fit ​​part 31 that can be detachably engaged with the snap-fit ​​part 72. Each snap-fit ​​part 31 is provided in a one-to-one correspondence with each snap-fit ​​part 72. The detachable arrangement between the snap-fit ​​part 72 and the snap-fit ​​part 31 enables the detachable engagement between the sweeping blades 3 and the connector 7, which facilitates the overall assembly and disassembly of the device.

[0059] Reference Figures 1-10The connecting body 71 can be a rod-shaped structure extending along each of the sweeping blades 3, and multiple snap-fit ​​pieces 72 are spaced apart along the axial direction of the connecting body 71. The sweeping blades 3 are provided with slots or blocks to achieve snap-fit ​​engagement with the snap-fit ​​pieces 72. Specifically, the snap-fit ​​piece 72 includes a snap-fit ​​body and a fastening body. The snap-fit ​​body connects the fastening body and the connecting body 71. The fastening body includes two fastening portions, each arranged in a semi-circular shape. The fastening body has a certain elasticity. The fastening portions are fixedly connected to the snap-fit ​​body, and the ends of the two fastening portions away from the snap-fit ​​body contact and engage. Under the action of elasticity, the two semi-circular fastening portions form a hollow circular structure.

[0060] The snap-fit ​​part 31 provided on the sweeping blade 3 includes an assembly groove provided on the sweeping blade 3. A snap-fit ​​block is provided in the middle of the assembly groove, which divides the assembly groove into a first sub-groove and a second sub-groove. The first sub-groove is located between the snap-fit ​​block and the movable part 2, and the other is the second sub-groove. The side of the second sub-groove away from the movable part 2 is provided with an open structure. The snap-fit ​​block is used to fasten into the circular structure of the snap-fit ​​part, thereby realizing the connection.

[0061] Specifically, when assembling the connector 7 with the sweeping blade 3, the locking part 72 of the connector 7 is positioned towards the sweeping blade 3. Then, the fastening body of the locking part 72 extends into the assembly groove of the sweeping blade 3 through the second slot. The contacting parts of the two fastening parts of the fastening body abut against the locking block. As the connector 7 continues to move, the two fastening parts separate under the obstruction of the locking block, thereby opening the circular structure. After the two fastening parts move to the first slot, they move closer to each other under their own elasticity, thereby closing the circular structure and confining the locking block within the circular structure. When it is necessary to disassemble the connector 7 from the sweeping blade 3, it is only necessary to move the connector 7 in the opposite direction, which is convenient for operation.

[0062] Of course, in order to ensure that the swinging of the sweeping blade 3 does not affect the connection between the connecting member 7 and the sweeping blade 3 during the movement of the pushing member 61, the opening direction of the assembly groove is set at an angle to the pushing direction of the pushing member 61. That is, the opening direction of the assembly groove and the pushing direction of the pushing member 61 are not parallel to each other. This ensures that the thrust of the pushing member 61 on the sweeping blade 3 will not cause the sweeping blade 3 to move along the opening direction of the assembly groove, thereby effectively avoiding the failure of the connection between the sweeping blade 3 and the connecting member 7 due to the pushing action of the pushing member 61.

[0063] Furthermore, the pusher 61 and the sweeping blades 3 connected to it move in the direction of movement of the movable member 2; through the connection between the pusher 61 and the sweeping blades 3, the movement of the pusher 61 drives the swinging of each sweeping blade 3 to achieve swinging air delivery. When swinging air delivery is not required, the sweeping blades 3 will move into the sweeping groove 102 along the direction of movement of the movable member 2. Through the movable cooperation between the pusher 61 and the sweeping blades 3, it is ensured that the connection between the pusher 61 and the sweeping blades 3 will not hinder the movement of the sweeping blades 3 during the process of the sweeping blades 3 moving into the sweeping groove 102.

[0064] Specifically, the movable part 2 is rotatably set, and the sweeping blade 3 rotates around the movable part 2 to enter and exit the sweeping groove 102. That is, the sweeping blade 3 has a clearance hole 33 through it along its own thickness direction. The clearance hole 33 is an arc-shaped hole with the rotation center of the movable part 2 as the center. The pusher 61 includes a first limiting part 611, a through part 612, and a second limiting part 613 connected to each other. The second limiting part 613 is used to connect with the second transmission component 6. The through part 612 is disposed through the clearance hole 33 and is movably engaged with the clearance hole 33 in the extending direction of the clearance hole 33. The first limiting part 611 and the second limiting part 613 are located on opposite sides of the sweeping blade 3, and the size of the wall surface of the first limiting part 611 and the second limiting part 613 connected with the through part 612 is larger than the opening size of the clearance hole 33. This ensures that the first limiting part 611 and the second limiting part 613 will not move into the clearance hole 33 or pass through the clearance hole 33 to other positions when the pusher 61 is pushed, thus ensuring the reliability of the overall connection of the device and ensuring the stable reciprocating swing of the sweeping blade 3.

[0065] Optionally, the sweeping blade 3 may also have a weight-reducing hole 32 extending through it. The weight-reducing hole 32 reduces the material used in the sweeping blade 3, lowering its cost, and also improves its elasticity, increasing the amplitude of its reciprocating oscillation to meet different user needs. The weight-reducing hole 32 can be a circular hole, a rectangular structure, or a long strip structure. This application provides two weight-reducing holes 32: one is a rectangular structure connected to the moving part 2 near the sweeping blade 3; the other is a long strip structure located at the bottom of the sweeping blade 3.

[0066] Reference Figures 1-10In some embodiments, a drive shaft 41 is rotatably connected to the driver 4. The first transmission assembly 5 includes a first driven shaft 51 and a first transmission shaft 52. The first driven shaft 51 and the first transmission shaft 52 are connected and disconnected by a first switch 53. The first driven shaft 51 is connected to the drive shaft 41 and the movable part 2. The drive motor is connected to the drive shaft 41 through its output shaft. Therefore, the rotation of the drive motor output shaft will drive the synchronous rotation of the drive shaft 41. When the first switch 53 controls the connection between the first driven shaft 51 and the first transmission shaft 52, the rotation of the drive shaft 41 will also drive the rotation of the first transmission shaft 52 through the first driven shaft 51, thereby driving the rotation of the movable part 2. The rotation of the movable part 2 enables the expansion and concealment of the sweeping blades 3.

[0067] The first drive shaft 52 and the movable part 2 can be connected by a key or by a gear set. In this application, a first bevel gear 55 is connected to the first drive shaft 52, and a second bevel gear 56 is connected to the movable part 2. The second bevel gear 56 and the first bevel gear 55 mesh with each other, thereby driving the rotation of the movable part 2 by rotating the first drive shaft 52.

[0068] The connection between the drive shaft 41 and the first driven shaft 51 can be made by a key or by a gear set. In this application, the drive shaft 41 is provided with a first drive gear 42 and the first driven shaft 51 is provided with a first driven gear 54. The first drive gear 42 and the first driven gear 54 mesh with each other, thereby driving the rotation of the first driven shaft 51 by the rotation of the drive shaft 41.

[0069] The first switch 53 can be any component that can control the connection between the first driven shaft 51 and the first transmission shaft 52. For example, the first switch can be an electromagnetic clutch. By controlling the electromagnetic clutch to be energized, the connection between the first driven shaft 51 and the first transmission shaft 52 is realized, and the first transmission shaft 52 is driven to rotate synchronously when the first driven shaft 51 rotates. By controlling the electromagnetic clutch to be de-energized, the connection between the first driven shaft 51 and the first transmission shaft 52 is broken. At this time, the rotation of the first driven shaft 51 will not affect the movement state of the first transmission shaft 52.

[0070] Reference Figures 1-10In some embodiments, the second transmission assembly 6 includes a second driven shaft 62 and a second transmission shaft 63. The second driven shaft 62 and the second transmission shaft 63 are connected and disconnected by a second switch 65. The second driven shaft 62 is connected to the drive shaft 41. The second transmission shaft 63 drives the pusher 61 to swing through a crank-rocker assembly. The rotation of the drive shaft 41 drives the second driven shaft 62 to rotate. When the second switch 65 controls the second driven shaft 62 to be connected to the second transmission shaft 63, the second transmission shaft 63 rotates synchronously with the rotation of the second driven shaft 62. Under the transmission action of the crank-rocker assembly, the rotational force is converted into a moving force, thereby driving the pusher 61 to move back and forth, and realizing the function of the sweeping blade 3 swinging back and forth.

[0071] The connection between the drive shaft 41 and the second driven shaft 62 can be made by a key or by a gear set. In this application, the drive shaft 41 is provided with a second drive gear 43, and the second drive gear 43 and the first drive gear 42 are spaced apart along the axial direction of the drive shaft 41. The second driven shaft 62 is provided with a second driven gear 64, and the second drive gear 43 and the second driven gear 64 mesh with each other, thereby driving the rotation of the second driven shaft 62 by the rotation of the drive shaft 41.

[0072] The second switch 65 can be any component that can control the connection between the second driven shaft 62 and the second transmission shaft 63. For example, the second switch can be an electromagnetic clutch. By controlling the electromagnetic clutch to be energized, the connection between the second driven shaft 62 and the second transmission shaft 63 is realized, and the second driven shaft 62 drives the second transmission shaft 63 to rotate synchronously when it rotates. By controlling the electromagnetic clutch to be de-energized, the connection between the second driven shaft 62 and the second transmission shaft 63 is broken. At this time, the rotation of the second driven shaft 62 will not affect the movement state of the second transmission shaft 63.

[0073] Specifically, the crank-rocker assembly includes a first connecting rod 66 connected to the second drive shaft 63. A second connecting rod 68 is connected to the end of the first connecting rod 66 via a slider 67. The slider 67 and the second connecting rod 68 are slidably engaged. One end of the second connecting rod 68 is hinged to the housing 1, and the other end of the second connecting rod 68 is hinged to the pusher 61 via a third connecting rod 69. A sliding hole is formed through the slider 67, and the second connecting rod 68 passes through this hole. Therefore, the rotation of the second drive shaft 63 drives the rotation of the first connecting rod 66. Under the action of the slider 67, the second connecting rod 68 oscillates back and forth, driving the pusher 61 to oscillate back and forth via the third connecting rod 69. Of course, the crank-rocker assembly in this application uses a combination of a swing guide rod mechanism and a crank-rocker mechanism to convert rotational force into reciprocating motion. Furthermore, the crank-rocker assembly can also be connected using other feasible components, such as a double-crank mechanism.

[0074] Reference Figures 1-10 In summary, when the sweeping blades 3 need to be hidden or unfolded, the second switch 65 is disconnected, the first switch 53 is connected, and the drive motor drives the drive shaft 41 to rotate. Under the transmission action of the first drive gear 42, the first driven shaft 51 rotates, which in turn drives the first driven shaft 51 to rotate. With the cooperation of the gear set, the moving part 2 rotates, driving each sweeping blade 3 to rotate into the sweeping groove 102 for hiding, or driving each sweeping blade 3 to rotate out of the sweeping groove 102 for unfolding. During this process, since the second switch 65 is disconnected, the rotation of the drive shaft 41, under the transmission action of the second drive gear 43, also drives the rotation of the second driven shaft 62. However, the second driven shaft 62 is not connected to the second drive shaft 63, so the pushing part 61 remains stationary, and therefore the sweeping blades 3 will not perform synchronous oscillating air-blowing movements.

[0075] Similarly, when the sweeping blades 3 need to perform sweeping operations, the first switch 53 is disconnected and the second switch 65 is connected. The drive motor drives the drive shaft 41 to rotate. The rotation of the drive shaft 41, under the transmission action of the second drive gear 43, drives the rotation of the second driven shaft 62. The connection of the second switch 65 connects the second driven shaft 62 to the second transmission shaft 63. The second transmission shaft 63 rotates synchronously and drives the crank rocker assembly to move, thereby driving the reciprocating oscillation of the pusher 61, realizing the oscillating air delivery of the sweeping blades 3. During this process, since the first switch 53 is disconnected, the rotation of the drive shaft 41, under the transmission action of the first drive gear 42, also drives the first driven shaft 51 to rotate. However, the first transmission shaft 52 is not connected to the first driven shaft 51, so the moving part 2 remains stationary. Therefore, the sweeping blades 3 do not synchronously unfold and retract.

[0076] Therefore, the air-sweeping device provided in this application can hide the sweeping blades 3 and open the air outlet 101 when the air-sweeping function is not required, thereby increasing the air volume and velocity and ensuring product performance. When the air-sweeping function is required, the sweeping blades 3 can be extended and reciprocated to achieve the sweeping effect. This device does not require disassembly and can be freely selected and controlled by the user.

[0077] Reference Figures 1-10 This application also provides an air conditioner that includes the air-sweeping device described in the foregoing embodiments.

[0078] Reference Figures 1-10 This application also provides a method for controlling an air conditioner, used to control the air conditioner as described in the foregoing embodiments, the method comprising:

[0079] When the blades are in the hidden state, the actuator 4 controls the sweeping blades 3 to move from the air outlet 101 to the sweeping slot 102;

[0080] In the air-sweeping state, the position of the air-sweeping blade 3 is detected. If the air-sweeping blade 3 is located in the air-sweeping groove 102, the driver 4 is controlled to drive the air-sweeping blade 3 to move from the air-sweeping groove 102 to the air outlet 101. If the air-sweeping blade 3 is located at the air outlet 101, the driver 4 controls each air-sweeping blade 3 to swing back and forth.

[0081] The position of the sweeping blade 3 can be detected by a sensor installed inside the housing 1. For example, the sensor can be an infrared sensor to determine whether the sweeping blade 3 is present at the air outlet 101. If it is, the sweeping blade 3 is considered to be in the deployed state; otherwise, it is considered to be in the concealed state. Alternatively, the sensor can be an angle sensor installed on the movable part 2, which determines the position of the sweeping blade 3 by measuring the rotation angle of the movable part 2.

[0082] The initial state of the air conditioner can be set to the state where the sweeping blades 3 are in the unfolded state. That is, at this time, the sweeping blades 3 are not in the sweeping slot 102, but are located at the air outlet 101. The sweeping blades 3 can be vertical to the horizontal plane. When the user presses the power button and sets the blade hiding function through the remote control, the sweeping blades 3 switch to the blade hiding state. The first switch 53 is energized, and the electromagnetic clutch plates of the first switch 53 are attracted together by magnetism. The drive motor starts and drives the moving part 2 to rotate through the first driving gear 42, the first driven gear 54, the first bevel gear 55 and the second bevel gear, etc., which drive the sweeping blades 3 to rotate synchronously. After the moving part 2 rotates to a specified angle, the sweeping blades are hidden in the sweeping slot 102 of the housing 1. After the action is completed, the drive motor is turned off, the first switch 53 is de-energized, and the electromagnetic clutch plates of the first switch 53 are disengaged.

[0083] When the user remotely sets the blades to unfold and activates the sweeping function, the system switches to sweeping mode. First, it checks if the sweeping blades 3 are unfolded. If not, the above actions are repeated, with the drive motor driving the movable part 2 to rotate at the opposite angle, thus unfolding the sweeping blades 3. After the sweeping blades 3 are unfolded, the following sweeping action is performed. If they are unfolded, the second switch is energized, the drive motor starts, and through the second driving gear 43, the second driven gear 64, and the crank-rocker assembly, the drive pusher 61 is activated, causing the sweeping blades 3 to reciprocate.

[0084] Of course, when the sweeping blades 3 are performing sweeping operations, the user can also set the swing angle of the sweeping blades 3. Based on the set swing angle, the actual rotation angle of the drive motor is calculated, and then the drive shaft 41 is driven to rotate, thereby making the sweeping blades 3 swing to the specified angle. After the action is completed, the drive motor is turned off, the second switch is de-energized, and the electromagnetic clutch plate of the second switch disengages, realizing the self-locking of the swing angle of the sweeping blades 3. When the user turns off the air conditioner, the current state of the sweeping blades 3 is detected, and the drive motor, the first switch and the second switch are driven to operate. The drive motor drives the drive shaft 41 to rotate a certain angle, so that the sweeping blades 3 return to the initial state.
