Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method and device for preventing direct airflow in an air conditioner based on a rocker slider reversing mechanism, and an air conditioner. Background Technology

[0002] Currently, air conditioners are a very common appliance, widely used in various living and working environments such as homes, offices, and shopping malls. Among these, the anti-direct-blow function is popular because it prevents the air conditioner's airflow from blowing directly on the user, improving comfort. In conventional anti-direct-blow mode, the airflow is typically directed upwards by adjusting the angle of the air deflector to achieve real-time anti-direct-blow. However, for taller users, the airflow may still blow onto their heads, thus failing to achieve the intended anti-direct-blow purpose.

[0003] In related technologies, a method for preventing direct airflow from an air conditioner is provided. The air outlet angle of the corresponding anti-direct airflow mode is determined based on the user's height, so that the air blown out at this air outlet angle is higher than the user's head, thereby achieving an anti-direct airflow effect suitable for the individual user.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] When controlling the rotation of the air guide plate, the angle of the air guide plate to prevent direct airflow is too high, which reduces the exposed area of ​​the air outlet, resulting in greater airflow resistance and thus greater air volume loss, affecting the air conditioning effect. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a method and device for controlling direct airflow in an air conditioner based on a rocker slider, and an air conditioner, to reduce airflow loss after adjusting the air outlet angle when the air conditioner is running in anti-direct airflow mode.

[0008] In some embodiments, the rocker-slider reversing air conditioner includes an air guide plate and a rocker-slider reversing drive mechanism for driving the air guide plate to rotate after extending out of the air conditioner outlet; the anti-direct-blow control method includes: obtaining a target guide plate angle of the air guide plate in response to an anti-direct-blow mode operation command; determining a target rotation angle of the rocker in the rocker-slider reversing drive mechanism based on the target guide plate angle; and controlling the motor in the rocker-slider reversing drive mechanism to rotate based on the target rotation angle of the rocker, so that the air guide plate rotates to the target guide plate angle.

[0009] In some embodiments, the anti-direct-blow control device for a rocker-slider reversing air conditioner includes: a first obtaining module configured to obtain a target guide plate angle of the air guide plate in response to an anti-direct-blow mode operation command; a second obtaining module configured to determine a target rotation angle of the rocker in the rocker-slider reversing drive mechanism based on the target guide plate angle; and a control module configured to control the motor in the rocker-slider reversing drive mechanism to rotate based on the target rotation angle of the rocker, so that the air guide plate rotates to the target guide plate angle.

[0010] In some embodiments, the anti-direct-blow control device for a rocker-slider reversing air conditioner includes a processor and a memory storing program instructions, wherein the processor is configured to execute the aforementioned anti-direct-blow control method for a rocker-slider reversing air conditioner when the program instructions are executed.

[0011] In some embodiments, the air conditioner includes: an air guide plate; a rocker-slider reversing drive mechanism for driving the air guide plate to rotate after extending out of the air conditioner outlet; and an anti-direct-blow control device as described above.

[0012] The anti-direct-blow control method and device for a rocker-slider reversing air conditioner, and the air conditioner provided in this disclosure, can achieve the following technical effects:

[0013] The anti-direct-blow control method provided in this embodiment uses a rocker-slider reversing mechanism to extend the air guide plate beyond the air outlet of the indoor unit of the air conditioner before rotating it. This creates a certain distance between the air guide plate and the air outlet, resulting in a large air delivery area at the air outlet and low air resistance for the airflow blowing out of the air conditioner. Furthermore, the rocker and motor in the rocker-slider reversing mechanism allow for adjustment of the air delivery angle of the air guide plate. In this way, without reducing the air delivery area of ​​the air outlet, the air guide plate achieves an anti-direct-blow angle, achieving air delivery away from people while reducing airflow loss and minimizing the impact on air conditioning performance. Thus, by controlling the rotation of the air guide plate through the rocker-slider reversing mechanism, the anti-direct-blow mode of the air conditioner is optimized and improved, thereby ensuring user comfort.

[0045] In this embodiment of the disclosure, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

[0046] In this embodiment of the disclosure, the terminal device refers to an electronic device with wireless connectivity. The terminal device can communicate with the aforementioned smart home appliances by connecting to the internet, or directly via Bluetooth, Wi-Fi, or other methods. In some embodiments, the terminal device may be, for example, a mobile device, a computer, or an in-vehicle device built into a hovercraft, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, or any combination thereof. Wearable devices may include, for example, smartwatches, smart bracelets, pedometers, etc.

[0047] Figure 1 This is a schematic diagram of an air conditioner usage scenario provided in an embodiment of this disclosure.

[0048] Combination Figure 1 As shown, this usage scenario includes an air conditioner 100 and a cloud server 110 for communicating with the air conditioner. The air conditioner 100 can be a common type of air conditioner used in home settings, such as a wall-mounted unit, a floor-standing unit, or a ducted unit.

[0049] Air Conditioner 100 can connect to the home's WiFi network and communicate with control terminals such as mobile phones and cloud servers. Users can also control Air Conditioner 100 to execute air conditioning commands through a smartphone application.

[0050] Air conditioner 100 communicates with cloud server 110 via WiFi network. Cloud server 110 is used to receive real-time status data of air conditioner 100 for big data platform and application service subscription, and also sends air conditioning commands from other business servers, big data platform, application terminal and smart terminal to air conditioner 100.

[0051] In other implementation scenarios of this solution, terminal devices may also be included for communicating with air conditioner 100 and / or cloud server 110. Here, terminal devices refer to smart devices in smart home application scenarios, such as smartphones, wearable devices, smart mobile devices, virtual display devices, etc., or smart home appliances, such as smart refrigerators, smart TVs, smart washing machines, smart air conditioners, smart speakers, smart lights, and smart curtains, or any combination thereof.

[0052] Figure 2 This is a schematic diagram of the connection relationship of the air conditioner processor provided in an embodiment of this disclosure.

[0053] Combination Figure 2 The air conditioner's processor 200 is used to receive and send information and instructions.

[0054] To achieve angle adjustment of the air guide plate, the air conditioner includes an air guide plate and a rocker-slider reversing drive mechanism for driving the rotation of the air guide plate. The rocker-slider reversing drive mechanism includes a motor and a rocker arm. The rocker arm is driven by the motor, which provides the driving force for the rotation of the rocker arm, thereby enabling the rocker arm to change the angle of the air guide plate. This solution is applied to the aforementioned air conditioner with a rocker-slider reversing drive mechanism, utilizing this structure to achieve angle adjustment of the air guide plate. The motor 210 is connected to the processor 200.

[0055] Furthermore, to achieve the anti-direct-blowing function of the air conditioner, some air conditioners are also equipped with a distance acquisition device for obtaining relative position information between the user and the air conditioner. This distance acquisition device can be a functional module installed in the air conditioner, or it can be a terminal device connected to the air conditioner via wired or wireless communication in a smart home scenario. This solution is applied to the aforementioned air conditioner equipped with a distance acquisition device, which is used to determine the relative position information between the user and the air conditioner. The distance acquisition device 220 is connected to the processor 200.

[0056] In some embodiments, the distance acquisition device 220 may be an infrared sensor, which calculates the distance between the air conditioner and the user by processing the time difference between transmitted and received signals. In other embodiments, the distance acquisition device 220 may also be an image acquisition module, which obtains the distance between the air conditioner and the user by acquiring an image of the user in the current scene, performing image processing.

[0057] In some embodiments, multiple terminal devices in a smart home scenario can also be used as distance acquisition devices. By acquiring the location information between the terminal devices and the user, the user's location in the smart home scenario can be determined. This information can then be combined with the installation location of the air conditioner to obtain the relative location information between the user and the air conditioner.

[0058] The processor 200 is used to receive data information sent by the cloud server and output control signals to the motor 210 according to the distance acquisition device 220.

[0059] Figure 4 This is an overall schematic diagram of the air conditioner provided in the embodiments of this disclosure; Figure 5 This is a schematic diagram of the connection structure between the air guide plate and the rocker slider reversing drive mechanism of the air conditioner provided in the embodiments of this disclosure.

[0060] The following explains the working relationship between the rocker-slider reversing air guide plate of the air conditioner and the rocker-slider reversing drive mechanism used to drive the air guide plate to rotate after it extends out of the air conditioner outlet.

[0061] Figure 5 and Figure 7 The image shows the position of the first drive shaft of the rocker arm in the slide groove when the air outlet is closed by the air guide plate, which can also be called the centering position of the first drive shaft of the rocker arm.

[0062] In some embodiments, the driving mechanism for the air guide plate 50 includes a rocker arm 10, an active slider 20, a driven slider 30, and a track plate 40. The rocker arm 10 is provided with a first transmission shaft 121; the active slider 20 is provided with a groove 21, one end of the active slider 20 is rotatably connected to the air guide plate 50, and the first transmission shaft 121 is slidably disposed in the groove 21; one end of the driven slider 30 is rotatably connected to the air guide plate 50; the track plate 40 is provided with a track portion, which is used to define the movement trajectory of the active slider 20 and the driven slider 30; wherein, the rocker arm 10 drives the active slider 20 and the driven slider 30 to move under the limitation of the track portion by sliding the first transmission shaft 121 in the groove 21, so that the air guide plate 50 first extends out of the air outlet to a first preset position and then rotates.

[0063] like Figure 7 As shown, when the air guide plate closes the air outlet, the first drive shaft 121 is in the center position of the slide groove. An elastic abutment is provided on the upper edge of the center position of the slide groove. The first drive shaft 121 abuts against the elastic abutment. The first drive shaft 121 pushes the active slider 20 to move upward, so that the active slider 20 pulls the air guide plate to close the air outlet.

[0064] When the air guide plate closes the air outlet, the first drive shaft 121 slides along the slide groove and gradually moves towards the center position of the slide groove. When the first drive shaft 121 of the rocker arm 10 moves to the center position of the slide groove, the first drive shaft 121 abuts against the elastic abutment, so that the first drive shaft 121 gives the active slider 20 an upward pushing force, pushing the active slider 20 to move upward. During the upward movement of the active slider 20, it pulls the air guide plate to close the air outlet.

[0065] The air conditioner air guide plate driving mechanism provided in this embodiment can generate a force that pushes the active slider 20 upward during the closing process of the air guide plate, thereby pulling the air guide plate to close the air outlet. This overcomes the problem of gaps between the air guide plate and the frame at the air outlet caused by manufacturing errors and installation gaps of the air guide plate, improves the tightness of the closure between the air guide plate and the air outlet, and thus improves the aesthetics of the air conditioner indoor unit.

[0066] It is understandable that "the active slider 20 moves upward" is not limited to vertical upward, but can also be inclined upward along the direction of movement of the active slider 20, as long as the active slider 20 can pull the air guide plate to close the air outlet in that direction.

[0067] Optionally, the elastic abutment includes a protrusion that protrudes into the groove. At the center position, the first drive shaft 121 is interference-fitted with the protrusion, and the elastic abutment deforms to push the active slider 20 to move upward.

[0068] The elastic abutment protrudes into the groove. When the air outlet is closed by the air guide plate, the first drive shaft 121 of the rocker arm 10 is in an interference fit with the protruding part of the elastic abutment at the center position. The elastic abutment is compressed by the first drive shaft 121 and deforms. Simultaneously, the elastic abutment on the active slider 20 is subjected to an upward pushing force generated by the compression, which in turn causes the first drive shaft 121 of the rocker arm 10 to push the active slider 20 upward.

[0069] Optionally, the elastic abutment can be an elastic material that deforms under the pressure of the first drive shaft 121 and can return to its original shape when not under the pressure of the first drive shaft 121, such as a spring, sheet 28, rubber, sponge, latex, etc.

[0070] Optionally, the shape of the elastic abutment can be semi-circular, semi-elliptical, trapezoidal, arched, or other irregular shapes with protrusions.

[0071] Optionally, the elastic abutment includes a spring piece 28. The spring piece 28 includes a first connecting end 281, a second connecting end 282, and a protruding section 283. The first connecting end 281 is fixedly connected to the upper edge, the second connecting end 282 is fixedly connected to the upper edge, and the protruding section 283 is disposed between the first connecting end 281 and the second connecting end 282. A deformation space is provided between the protruding section 283 and the upper edge. At the centering position, the protruding section 283 is pressed into the deformation space by the first drive shaft 121, thereby actuating the active slider 20 to move upward. Figures 9 to 11 As shown.

[0072] The area between the raised section 283 and its upper edge is not solid; that is, a deformation space is provided between the raised section 283 and its upper edge. When the first drive shaft 121 compresses the raised section 283 of the spring sheet 28, the raised section 283 deforms into the deformation space, generating a compressive force that drives the active slider 20 to move upward. Optionally, the raised section 283 can be flat or curved.

[0073] Optionally, the spring 28 further includes a first abutting guide section 284 and a second abutting guide section 285. The first abutting guide section 284 is disposed between the first connecting end 281 and the protruding section 283, and the second abutting guide section 285 is disposed between the second connecting end 282 and the protruding section 283. The distances from the first abutting guide section 284 and the second abutting guide section 285 to the upper edge are both less than the distance from the protruding section 283 to the upper edge.

[0074] Optionally, the first abutment guide section 284 can be an arc or slope shape connecting the first connecting end 281 and the protruding section 283, to guide the first drive shaft 121 of the rocker arm 10 to slide along the first abutment guide section 284 and slide to the protruding section 283 of the spring piece 28. The second abutment guide section 285 can be an arc or slope shape connecting the second connecting end 282 and the protruding section 283, to guide the first drive shaft 121 of the rocker arm 10 to slide along the second abutment guide section 285 until it disengages from the spring piece 28. The distances from the first abutment guide section 284, the second abutment guide section 285, and the protruding section 283 to the upper edge can be understood as the vertical distances from the first abutment guide section 284, the second abutment guide section 285, and the protruding section 283 to the upper edge, respectively.

[0075] Optionally, the distance from the protrusion 283 to its upper edge is less than or equal to the radius of the first drive shaft 121.

[0076] The gap between the air guide plate and the air outlet frame is small due to manufacturing errors and assembly clearances. Therefore, the distance from the raised section 283 to its upper edge does not need to be large; it can be less than or equal to the radius of the first drive shaft 121. If the distance from the raised section 283 to its upper edge is too large, it will also affect the normal sliding of the first drive shaft 121 of the rocker arm 10 along the slide groove.

[0077] Optionally, the lower edge of the chute at its center position is provided with a clearance groove 29 to avoid the first drive shaft 121. For example... Figure 8 and Figure 9 As shown.

[0078] When the first drive shaft 121 abuts against the elastic abutment, it will also move slightly downwards. A relief groove 29 is provided at the lower edge of the groove at its center position to allow the first drive shaft 121 to move downwards, providing space for this downward movement. Optionally, the downward displacement of the first drive shaft 121 is limited, and the vertical distance from the relief groove 29 to the lower edge does not need to be too large; it can be less than or equal to the radius of the first drive shaft 121.

[0079] The following embodiments illustrate the structure of the air conditioner air guide plate drive mechanism, including the rocker arm, active slider, driven slider, and track plate, as well as the process of the drive mechanism driving the air guide plate to rotate.

[0080] Optionally, the driving force for the movement of the active slider 20 comes from the rocker arm 10. The rocker arm 10 provides the driving force for the movement of the active slider 20 by sliding the first transmission shaft 121 within the slide groove 21. One end of both the active slider 20 and the driven slider 30 is connected to the air guide plate 50, and the driving force is transmitted to the driven slider 30 through the connection point between the air guide plate 50 and the driven slider 30, causing the driven slider 30 to move. Under the constraint of the track plate 40, the active slider 20 and the driven slider 30 first drive the air guide plate 50 to extend out of the air outlet to a first preset position, and then drive the air guide plate 50 to rotate. In this way, the movement of the slider assembly can be driven by one rocker arm 10, which in turn drives the air guide plate 50 to extend out of the air outlet and rotate to guide the air. The driving mechanism has a tight fit and a simple structure. At the same time, the rotation of the air guide plate 50 extending out of the air conditioner allows for large-angle air guidance, expanding the air supply range of the air conditioner.

[0081] Optionally, both the active slider 20 and the driven slider 30 are rotatably connected to the air guide plate 50. Optionally, one end of the active slider 20 is provided with a first connecting hole 27, and one end of the driven slider 30 is provided with a second connecting hole 34.

[0082] Optionally, the active slider 20 is further provided with at least two sliding posts that move along the track, including a first sliding post 25 at the top and a second sliding post 26 in the middle.

[0083] Optionally, the driven slider 30 has three sliding posts on its second plate surface opposite to the first plate surface. The three sliding posts are arranged in a triangle, such as... Figure 14 As shown, these are the third sliding post 31, the fourth sliding post 32, and the fifth sliding post 33, respectively. This improves the limiting effect of the track plate 40 on the movement trajectory of the driven slider 30.

[0084] Optionally, the driven slider 30 is provided with a through slide 35 that passes through its own plate surface, and the plate surface opposite to the driven slider 20 is provided with a sliding post, which passes through the through slide 35 and moves along the track.

[0085] Optionally, the track section includes a first track and a second track. The first track is herringbone shaped and is used to limit the movement of the active slider 20. The second track is straight and is located below the first track along the direction of the extension of the air guide plate 50. The second track is used to limit the linear movement of the driven slider 30. Under the constraints of the first and second tracks, the active slider 20 and the driven slider 30 first move synchronously in a straight line, driving the air guide plate 50 to a first preset position. After that, the active slider 20 changes direction and generates relative movement with the driven slider 30, thereby driving the air guide plate 50 to rotate.

[0086] In this embodiment of the disclosure, the first preset position is the position where the air guide plate 50 extends out of the air conditioner and is about to start rotating, such as... Figure 16 As shown, at this time, there is a certain distance between the air guide plate 50 and the air outlet, and the air guide plate 50 can be opened upward or downward at the first preset position. In this embodiment of the present disclosure, the rotation position of the air guide plate 50 is not limited to the first preset position. The first preset position is the initial position of the rotation of the air guide plate 50. The rotation of the air guide plate 50 can be understood as extending and rotating at the same time.

[0087] Optionally, the first track includes a first straight track 41, a first branch track 42, and a second branch track 43; the first branch track 42 is connected to the first straight track 41, the second branch track 43 is connected to the first straight track 41, and the first branch track 42 and the second branch track 43 extend in different directions.

[0088] In this embodiment, the first sliding post 25 of the active slider 20 moves within the first track, and the second sliding post 26 of the active slider 20 moves within the second track. When the first sliding post 25 moves from the first straight track 41 to the first branch track 42 or the second branch track 43, the active slider 20 will have relative motion with the driven slider 30, and the active slider 20 will change direction.

[0089] Optionally, the second track includes three straight tracks: a second straight track 44, a third straight track 45, and a fourth straight track 46. During the extension and rotation of the air guide plate 50, the driven slider 30 moves linearly along the three straight tracks of the second track. Specifically, the third sliding post 31 moves within the second straight track 44, the fourth sliding post 32 moves within the third straight track 45, and the fifth sliding post 33 moves within the fourth straight track 46. That is, the driven slider 30 moves linearly under the constraint of the three tracks.

[0090] It is understandable that the direction of the first linear track 41 and the direction of the second track are the same as the direction in which the air guide plate 50 extends from the closed state to the first preset position.

[0091] Optionally, the slide 21 is linear, and the first drive shaft 121 slides within the slide 21, thereby driving the movement of the active slider 20. Understandably, the direction of the slide 21 can be perpendicular to the direction in which the air guide plate 50 extends from the closed state to the first preset position, or it can have a preset angle. This application does not specifically limit the direction of the slide 21.

[0092] Optionally, the diameter of the circle formed by the movement of the first drive shaft 121 of the rocker arm 10 is less than or equal to the length of the slide groove 21. This allows the first drive shaft 121 of the rocker arm 10 to rotate 90° from its initial position along a first or second direction and continue to rotate, with the rotation angle of the first drive shaft 121 not limited by the length of the slide groove 21.

[0093] Optionally, the joystick 10 is also provided with a second drive shaft 122, and the active slider 20 is also provided with a limiting groove 23. The second drive shaft 122 is slidably disposed in the limiting groove 23. The second drive shaft 122 slides in the limiting groove 23 to provide driving force for the movement of the active slider 20.

[0094] Optionally, the limiting groove 23 is flared and funnel-shaped. The inner edge of the limiting groove 23 includes a first flared section 231, a U-shaped section 233, and a second flared section 232 connected in sequence. The first flared section 231 and the second flared section 232 are located on both sides of the U-shaped section 233. Optionally, the first flared section 231 is provided with a first limiting point where the second drive shaft 122 abuts, and the second flared section 232 is provided with a second limiting point where it abuts the second drive shaft 122. In this embodiment, the first limiting point is as follows: Figure 12 The first limit site is represented by A, and the second limit site is represented by B.

[0095] The first drive shaft 121 of the rocker arm 10 moves within the groove 21 of the active slider 20, providing driving force for the movement of the active slider 20. The second drive shaft 122 of the rocker arm moves within the limiting groove 23. Understandably, at the first limiting point A and the second limiting point B, the second drive shaft 122 begins to have contact with the inner edge of the limiting groove 23, enabling the active slider 20 to overcome gravity and move along a preset track. Through the contact force between the second drive shaft 122 and the first limiting point A or the second limiting point B, the first sliding post 25 of the active slider 20 is provided with driving force to select either the first branch track 42 or the second branch track 43 for movement.

[0096] Optionally, the rocker includes a rotating disk 11 and a rotating rod 12. The rotating disk 11 has a rotation center and a notch 111. The first end of the rotating rod 12 is fixedly connected to the notch 111, and the second end of the rotating rod 12 is a free end.

[0097] Optionally, the joystick is connected to a motor drive, and the motor provides driving force for the rotation of the joystick, thereby enabling the joystick to slide and connect with the active slider 20 and drive the active slider 20 to move.

[0098] Optionally, the first drive shaft 121 is disposed at the free end of the rotating rod 12. In this way, the first drive shaft 121 can slide on the active slider 20, thereby driving the active slider 20 to move. Understandably, the rotating disk 11 has a driving surface that contacts the motor, the rotating rod 12 has a rotating surface that contacts the slider, and the first drive shaft 121 is disposed on the rotating surface of the rotating rod 12.

[0099] Optionally, the joystick also includes a second drive shaft 122, which is used to redirect the movement of the active slider 20. The second drive shaft 122 is disposed on the rotation surface of the rotating rod 12 and is located between the first end of the rotating rod 12 and the first drive shaft 121. The second drive shaft 122 can provide the active slider 20 with the driving force to select the track.

[0100] The driving mechanism for the air guide plate 50 provided in this embodiment drives the air guide plate 50 to move in the following way:

[0101] The initial state of the moving components of the air guide plate 50 in the closed state is as follows: Figure 5 As shown. When the joystick 10 is from Figure 5 When the initial position shown rotates along the first or second direction, the first drive shaft 121 slides within the groove 21 of the active slider 20 to drive the active slider 20 and the driven slider 30 to move. The active slider 20 moves linearly along the straight segment of the first linear track 41, and the driven slider 30 moves linearly along the second track, thereby driving the air guide plate 50 to move linearly to the first preset position. The first preset position can be understood as the position of the air guide plate 50 corresponding to the end of the straight segment when the first sliding post 25 of the active slider 20 moves. In this embodiment, the first direction is clockwise, and the second direction is counterclockwise.

[0102] When the rocker arm 10 rotates in the first direction, and the air guide plate 50 reaches the first preset position, the second drive shaft 122 of the rocker arm 10 moves to the first limit point A. Because there is a contact force between the second drive shaft 122 and the first limit point A, it provides a driving force for the first sliding post 25 of the active slider 20 to select the track. This causes the first sliding post 25 of the active slider 20 to enter the first branch track 42 from the first straight track 41. The second sliding post 26 of the active slider 20 passes through the through slide 35 of the driven slider 30 and continues to move within the second straight track 44, causing the active slider 20 to change direction. Simultaneously, the driven slider 30 continues to move linearly along the second track. Thus, the air guide plate 50 opens upwards under the combined action of the active slider 20 and the driven slider 30. Figure 17 As shown.

[0103] When the rocker arm 10 rotates in the second direction, and the air guide plate 50 reaches the first preset position, the second drive shaft 122 of the rocker arm 10 moves to the second limit point B. Due to the contact force between the second drive shaft 122 and the second limit point B, a driving force is provided to the first sliding post 25 of the active slider 20 to select the track. This causes the first sliding post 25 of the active slider 20 to enter the second branch track 43 from the first straight track 41. The second sliding post 26 of the active slider 20 passes through the through slide 35 of the driven slider 30 and continues to move within the second straight track 44, causing the active slider 20 to change direction. Simultaneously, the driven slider 30 continues to move linearly along the second track. Thus, the air guide plate 50 opens downwards under the combined action of the active slider 20 and the driven slider 30. Figure 18 As shown.

[0106] The following section explains the anti-direct-blow control method for the rocker-slider reversing air conditioner described above.

[0107] Figure 3 This is a flowchart illustrating an anti-direct-blow control method for an air conditioner based on a rocker-slider reversing mechanism, provided in this embodiment. The method is applied to the aforementioned air conditioner with a rocker-slider reversing drive mechanism. This anti-direct-blow control method can be executed by the air conditioner's processor, or in a server, such as a cloud server communicating with the air conditioner; it can also be executed at a terminal device, such as a smartphone or the control terminal of a smart home appliance. In this embodiment, the air conditioner's processor is used as the execution entity to describe the solution.

[0108] Step S301: In response to the anti-direct-blow mode operation command, obtain the target guide plate angle of the air guide plate.

[0109] The target guide plate angle of the air guide plate refers to the air delivery angle that can achieve the purpose of avoiding people when delivering air.

[0110] In some optional embodiments, the air conditioner's remote control and control panel are equipped with an "anti-direct-blow function" airflow option, which can be used to trigger the execution of the air conditioner's anti-direct-blow control method in this embodiment. Thus, after the user selects the anti-direct-blow function option, the air conditioner generates relevant operating instructions and executes them.

[0111] In some alternative embodiments, the air conditioner may also generate relevant anti-direct-blow mode operation commands through temperature detection triggering, human sensation detection triggering, timed triggering, etc.

[0112] For example, when the air conditioner is operating in cooling mode, if the difference between the ambient temperature and the set temperature exceeds a first threshold, the anti-direct-blow mode operation command is triggered. Thus, when there is a significant temperature difference between the ambient and set temperatures, triggering this anti-direct-blow mode operation command prevents the air from blowing directly on the user, thus avoiding discomfort.

[0113] For example, when the air conditioner is running in cooling mode, the anti-direct-blow mode is triggered when a user is detected indoors. Thus, by detecting human presence, the anti-direct-blow mode is activated when a user is present, preventing direct airflow from blowing directly on the user.

[0114] Step S302: Determine the target rotation angle of the rocker arm in the rocker arm slider reversing drive mechanism based on the target guide plate angle.

[0115] As shown in the previous embodiment, the rotation of the joystick drives the active and driven sliders to move, which in turn drives the air guide plate to rotate. Therefore, based on the target air guide plate angle, the target rotation angle of the joystick required to drive the air guide plate to rotate to that angle can be obtained.

[0116] Step S303: Based on the target rotation angle of the joystick, control the motor in the joystick slider reversing drive mechanism to rotate so that the air guide plate rotates to the target guide plate angle.

[0117] The joystick is connected to a motor drive, which provides the driving force for the joystick's rotation. This allows the joystick to slide and connect with the active slider, driving the active slider to move, thereby rotating the air guide plate. Therefore, after determining the target rotation angle of the joystick, the motor is controlled to rotate so that the joystick can reach the target rotation angle, thus achieving the target angle for the air guide plate to deliver air away from people.

[0118] The anti-direct-blow control method provided in this embodiment utilizes a rocker-slider reversing mechanism to extend the air guide plate beyond the air outlet of the indoor unit before rotating. This creates a distance between the air guide plate and the air outlet, resulting in a large air delivery area and low air resistance for the airflow from the air conditioner. Furthermore, the rocker and motor in the rocker-slider reversing mechanism allow for adjustment of the air delivery angle of the air guide plate. Thus, without reducing the air delivery area of ​​the air outlet, the air guide plate achieves an anti-direct-blow angle, minimizing airflow loss and impacting air conditioning performance while avoiding direct airflow to people. Therefore, by controlling the rotation of the air guide plate through the rocker-slider reversing mechanism, the anti-direct-blow mode of the air conditioner is optimized and improved, thereby ensuring user comfort.

[0119] Optionally, the target guide plate angle of the air guide plate is obtained, including:

[0120] Obtain the first angle value between the air guide plate and the vertical plane when the air guide plate is closed;

[0121] The second included angle value of the air guide plate is determined based on the relative position parameters between the air conditioner and the user; the relative position parameters include the horizontal distance parameter and the vertical distance parameter between the air conditioner outlet and the user;

[0122] The angle of the target guide plate is determined based on the first included angle value and the second included angle value.

[0123] Here, the value of the first included angle is related to the air duct design of the air conditioner's outlet; different products have different first included angle values. The correspondence between air conditioner models and their corresponding first included angle values ​​can be stored in a database. Once the current air conditioner model is determined, the corresponding current first included angle value can be obtained.

[0124] Specifically, the angle between the tangent on the outer surface of the air guide plate and the vertical plane is taken as the first angle value.

[0125] In this embodiment, since the air outlet of the air conditioner is designed to be angled downwards at 45° when there is no air guide plate, the first angle between the tangent on the outer surface of the air guide plate and the vertical plane is set to 47°.

[0126] Furthermore, the second included angle value is used as an angle value related to the current user's position. Here, the horizontal distance parameter between the air conditioner vent and the user indicates the distance between the user and the air conditioner; the vertical distance parameter between the air conditioner vent and the user indicates the height difference between the user and the air conditioner vent.

[0127] For example, for users of the same height, the closer they are to the air conditioner, the higher the angle at which the air conditioner's air deflector needs to be raised to prevent direct airflow; for users at the same distance from the air conditioner, the taller they are, the higher the angle at which the air conditioner's air deflector needs to be raised to prevent direct airflow.

[0128] Specifically, the arctangent of the ratio of the vertical distance parameter between the air conditioner outlet and the user to the horizontal distance parameter is used as the second included angle value.

[0129] Optionally, obtaining the vertical distance parameter includes:

[0130] Get the current vertical height between the highest point of the user's head and the air conditioner vent.

[0131] The sum of the current vertical height and the height adjustment value is used as the vertical distance parameter; the height adjustment value is greater than 0.

[0132] Here, by setting a height adjustment value, a margin is provided for obtaining the second included angle value. When the user's height increases in a short period (such as suddenly moving closer or stepping on an object), the air conditioner does not need to make a corresponding angle adjustment, thus ensuring the anti-direct-blowing air delivery effect. The height adjustment value can be 15cm-25cm, for example, 15cm, 20cm, and 25cm. In this embodiment, the height adjustment value is set to 20cm. In other embodiments, the height adjustment value can be determined according to the user's identity. For example, when the user is a child, the height adjustment value is set to the first height adjustment value; when the user is an adult, the height adjustment value is set to the second height adjustment value; the first height adjustment value is less than the second height adjustment value. As another example, the height adjustment value can be determined based on the horizontal distance parameter between the user and the air conditioner; when the horizontal distance parameter is greater than a horizontal distance threshold, the height adjustment value is set to the third height adjustment value; when the horizontal distance parameter is less than or equal to the horizontal distance threshold, the height adjustment value is set to the fourth height adjustment value; the third height adjustment value is less than the fourth height adjustment value.

[0133] Figure 19 A schematic diagram showing the positional relationship between the air conditioner and the user is provided. Figure 19 It can be seen that after obtaining the first and second included angle values ​​mentioned above, the target guide plate angle is determined in the following way:

[0134] A3 = 90° - A1 + A2

[0135] Where A3 is the target guide plate angle, A1 is the first included angle value, and A2 is the second included angle value.

[0136] In this way, after obtaining the target guide plate angle, the rotation control strategy of the joystick can be determined by the correspondence between the guide plate angle and the joystick rotation angle, so that the guide plate reaches the angle value A3.

[0137] Optionally, the target rotation angle of the rocker arm in the rocker arm slider reversing drive mechanism is determined based on the target guide plate angle, including:

[0138] Based on the correspondence between the guide plate angle and the rocker rotation angle in the rocker slider reversing drive mechanism, determine the target rocker rotation angle corresponding to the current target guide plate angle;

[0139] Among them, the guide plate angle of the air guide plate is positively correlated with the rotation angle of the rocker arm.

[0140] Here, the correspondence between the guide plate angle and the joystick rotation angle can be obtained through experimentation, and a formula can be fitted based on this correspondence. After obtaining the current target angle of the guide plate, the target rotation angle of the joystick can be calculated using the formula.

[0141] For example, the relationship between the guide plate angle and the joystick rotation angle can be expressed by the following formula:

[0142] A3=k1×X+m

[0143] Where A3 is the guide plate angle, X is the joystick rotation angle, m is the correction value, k1 is the first weighting coefficient, and k1 is greater than 0.

[0144] In addition, the correspondence between the guide plate angle and the joystick rotation angle can also be stored in the database in the form of a correspondence table. After obtaining the current target angle of the guide plate, the joystick rotation angle corresponding to the target angle of the guide plate can be obtained by retrieving the database.

[0145] The values ​​of the first weighting coefficient k1 and the correction value m can be obtained through data fitting. Optionally, the correspondence between the guide plate angle of the air guide plate and the rocker rotation angle in the rocker-slider reversing drive mechanism can be obtained as follows:

[0146] With the air guide plate in a closed state as the initial state, the joystick is controlled to rotate according to a preset range value, and the corresponding air guide plate angle is obtained after each rotation;

[0147] A scatter plot of the joystick rotation angle and the air guide plate angle is obtained by plotting the joystick rotation angle on the horizontal axis and the air guide plate angle on the vertical axis.

[0148] By fitting the scatter plot with the fitting function, the corresponding relationship between the guide plate angle and the rocker arm rotation angle can be obtained.

[0149] For example, Figures 20a-20e A schematic diagram showing the relationship between the joystick rotation angle and the air guide plate angle is presented, and the numerical relationship between the joystick rotation angle and the air guide plate angle shown in Table 1 is obtained.

[0150] Table 1

[0151]

[0152]

[0153] After fitting the data from Table 1 to the x and y coordinates, we obtain k1 = 0.69 and m = -43.96. Therefore, the relationship between the guide vane angle and the rocker arm rotation angle is:

[0154] A3 = 0.69X - 43.96

[0155] Where A3 is the guide plate angle and X is the joystick rotation angle.

[0156] After determining the target rotation angle of the joystick, it is necessary to control the motor to drive the joystick to rotate, so it is necessary to obtain the motor control strategy.

[0157] Optionally, based on the target rotation angle of the joystick, the rotation of the motor in the joystick slider reversing drive mechanism is controlled, including:

[0158] Based on the correspondence between the joystick rotation angle and the number of motor rotation steps, determine the relative number of motor rotation steps corresponding to the target joystick rotation angle;

[0159] Get the current number of steps the motor has rotated;

[0160] The target number of motor rotation steps and the target rotation direction are determined based on the difference between the relative number of motor rotation steps and the current number of rotation steps.

[0161] The motor rotation is controlled based on the target number of rotation steps and the target rotation direction.

[0162] Here, the correspondence between the joystick rotation angle and the number of motor rotation steps can be obtained through experimentation, and a formula can be fitted based on this correspondence. After obtaining the current target joystick rotation angle, the required relative number of motor rotation steps can be calculated using the formula.

[0163] Here, the relative rotation steps of the motor refer to the total number of steps required for the motor to rotate from its initial position (with the air guide closed) until the joystick reaches the target rotation angle and the air guide reaches the target guide angle.

[0164] Alternatively, the relationship between the number of motor rotation steps and the joystick rotation angle can be expressed by the following formula:

[0165] X = k2 × Y + n

[0166] Where X is the joystick rotation angle, Y is the number of motor rotation steps, n is the correction value, and k2 is the first weighting coefficient, which is greater than 0.

[0167] In addition, the correspondence between the number of motor rotation steps and the joystick rotation angle can also be stored in the database in the form of a correspondence table. After obtaining the current target rotation angle of the joystick, the relative number of motor steps corresponding to the target rotation angle of the joystick can be obtained by retrieving the database.

[0168] For example, the correspondence between the number of motor rotation steps and the joystick rotation angle is as follows:

[0169] X = [0.027Y]

[0170] Where X is the joystick rotation angle and Y is the number of motor rotation steps.

[0171] For example, when the target rotation angle of the joystick is 170°, the relative rotation steps of the motor are Y = 170 / 0.27, which, after rounding, yields Y = 6296.

[0172] After obtaining the relative rotation steps of the motor, it is necessary to control the motor rotation based on the number of steps the motor has rotated relative to the initial position.

[0173] For example, the target number of motor rotation steps and the target rotation direction are determined based on the difference between the relative number of motor rotation steps and the current number of rotation steps, including:

[0174] The absolute value of the difference between the relative number of motor rotation steps and the current number of rotation steps is taken as the target number of motor rotation steps.

[0175] If the difference between the relative rotation steps of the motor and the current rotation steps is greater than 0, the motor is controlled to rotate in a direction that moves away from the initial position of the joystick after rotation; if the difference between the relative rotation steps of the motor and the current rotation steps is less than 0, the motor is controlled to rotate in a direction that moves closer to the initial position of the joystick after rotation.

[0176] In this way, by controlling the rotation of the air guide plate through the rocker-slider reversing mechanism, the air conditioner's anti-direct-blow mode is optimized and improved, thereby ensuring user comfort.

[0177] Figure 21 This is a flowchart illustrating an anti-direct-blow control method for an air conditioner based on a rocker-slider reversing mechanism, provided in this embodiment of the disclosure. The method is applied to the aforementioned air conditioner with a rocker-slider reversing drive mechanism. In this embodiment, the air conditioner's processor is used as the executing entity to describe the solution.

[0178] Step S2101: After the rocker slider reversing drive mechanism drives the air guide plate to extend out of the air conditioning outlet, the corresponding air conditioning program is executed.

[0179] Step S2102: In response to the anti-direct-blow mode operation command, obtain the target guide plate angle of the air guide plate.

[0180] In this embodiment, the target angle is determined in the following way:

[0181]

[0182] Where A3 is the target guide plate angle, H is the current vertical height between the highest point of the user's head and the air conditioner vent, h is the height adjustment value, and L is the horizontal distance parameter between the air conditioner vent and the user.

[0183] Step S2103: Based on the correspondence between the guide plate angle of the air guide plate and the rotation angle of the rocker arm, and the correspondence between the rotation angle of the rocker arm and the number of rotation steps of the motor, determine the relative rotation steps of the motor.

[0184] Step S2104: Obtain the current difference between the relative number of motor steps and the current number of rotation steps. If the current difference is greater than 0, control the motor to move forward according to the absolute value of the current difference; if the current difference is less than 0, control the motor to move backward according to the absolute value of the current difference.

[0185] The anti-direct-blow control method provided in this embodiment uses a rocker-slider reversing mechanism to extend the air guide plate beyond the air outlet of the indoor unit of the air conditioner before rotating it. This creates a certain distance between the air guide plate and the air outlet, resulting in a large air delivery area at the air outlet and low air resistance for the airflow blowing out of the air conditioner. Furthermore, the rocker and motor in the rocker-slider reversing mechanism allow for adjustment of the air delivery angle of the air guide plate. In this way, without reducing the air delivery area of ​​the air outlet, the air guide plate achieves an anti-direct-blow angle, achieving air delivery away from people while reducing airflow loss and minimizing the impact on air conditioning performance. Thus, by controlling the rotation of the air guide plate through the rocker-slider reversing mechanism, the anti-direct-blow mode of the air conditioner is optimized and improved, thereby ensuring user comfort.
