Description

Technical Field

[0001] This invention relates to the field of air handling equipment technology, and in particular to a control method for an air conditioner and an air conditioner. Background Technology

[0002] In related technologies, as living standards improve, consumers are increasingly valuing the user experience of consumer products. In the air conditioning sector, users not only demand high cooling and heating performance, but also increasingly higher levels of comfort and overall user experience from air conditioners. When an air conditioner is turned on for cooling, the cold air blows directly onto the body, causing discomfort. While the "no-wind" mode avoids direct cold air, the cooling effect is poor, and after running in this mode for a period, the indoor temperature tends to rise, leading to heat and discomfort for the user, significantly reducing comfort and overall user experience. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a control method for an air conditioner, which can automatically switch to a draftless operating mode to adjust the cooling capacity based on the indoor ambient temperature, simultaneously considering both the draftless effect and the cooling effect, thereby improving the intelligence of the air conditioner and the user experience.

[0004] The present invention also proposes an air conditioner that operates according to the above-described air conditioner control method.

[0005] According to an embodiment of the present invention, a control method for an air conditioner includes: determining that the air conditioner is in cooling mode; determining that the air conditioner is in windless mode; acquiring the indoor ambient temperature where the air conditioner is located; and controlling the air conditioner to operate in a first windless mode or a second windless mode based on the indoor ambient temperature, wherein the cooling capacity of the air conditioner in the second windless mode is greater than the cooling capacity of the air conditioner in the first windless mode. The air conditioner includes a housing and an air guide plate assembly. The housing has an air outlet extending horizontally. The air guide plate assembly includes a first air guide plate and a second air guide plate. The first air guide plate and the second air guide plate are movably disposed at the air outlet to open or close the air outlet. When the first air guide plate opens the air outlet, the upper end of the first air guide plate flips downward, and the lower end of the first air guide plate first descends and then flips upward. When the second air guide plate opens the air outlet, the upper end of the second air guide plate rotates downward. At least one of the first air guide plate and the second air guide plate has a plurality of spaced-apart micropores.

[0006] According to the air conditioner control method of the present invention, when the air conditioner is in windless mode, it can operate in either a first windless mode or a second windless mode based on the acquired indoor ambient temperature. The cooling capacity of the air conditioner in the second windless mode is greater than that in the first windless mode. This allows for windless airflow when the user does not want drafts. The air conditioner automatically switches between windless operating modes based on the indoor ambient temperature, automatically increasing the cooling capacity when the room temperature is high. This ensures both windless and effective cooling without requiring manual adjustment or control by the user when they feel uncomfortable. This improves the intelligence and automation of the air conditioner, thereby enhancing user comfort and experience.

[0007] According to some embodiments of the present invention, determining whether the air conditioner operates in a first windless mode or a second windless mode based on the indoor ambient temperature includes: determining that the air conditioner operates in a first windless mode when the indoor ambient temperature is less than or equal to a preset temperature value, and determining that the air conditioner operates in a second windless mode when the indoor ambient temperature is greater than the preset temperature value.

[0008] According to some embodiments of the present invention, obtaining the indoor ambient temperature where the air conditioner is located includes: obtaining the return air temperature at the return air vent of the air conditioner as the indoor ambient temperature.

[0013] According to some embodiments of the present invention, in the first windless mode and the second windless mode, the first air guide plate opens the air outlet from the bottom, the second air guide plate rotates to the outside of the air outlet, and the air outlet end of the first air guide plate abuts against the air outlet end of the second air guide plate. In the first windless mode, the distance between the upper end of the width direction of the first air guide plate and the upper end of the width direction of the air outlet is h1 in the up-down direction. In the second windless mode, the distance between the upper end of the width direction of the first air guide plate and the upper end of the width direction of the air outlet is h2 in the up-down direction, and h2 > h1.

[0014] In some embodiments of the present invention, h1 satisfies: 5mm < h1 ≤ 15mm; and / or, h2 satisfies: 15mm < h2 < 30mm.

[0015] According to some embodiments of the present invention, when the air conditioner is in the off state, the first air guide plate closes the air outlet, and the second air guide plate is located outside the first air guide plate and is stacked with the first air guide plate.

[0016] In some embodiments of the present invention, the air guide plate assembly further includes a first rod and a second rod. One end of the first rod is rotatably connected to the housing, and the other end is rotatably connected to the first air guide plate. One end of the second rod is rotatably connected to the housing, and the other end is rotatably connected to the first air guide plate. The second rod is located above the first rod and is spaced apart from the first rod in the vertical direction. In the off state of the air conditioner, on a cross-section perpendicular to the length direction of the first air guide plate, the line connecting the rotation axes at both ends of the second rod in the length direction is the first connecting line. In the first windless mode, on a cross-section perpendicular to the length direction of the first air guide plate, the angle between the line connecting the rotation axes at both ends of the second rod in the length direction and the first connecting line is α1. In the second windless mode, on a cross-section perpendicular to the length direction of the first air guide plate, the angle between the line connecting the rotation axes at both ends of the second rod in the length direction and the first connecting line is α2, and satisfies: α2 > α1.

[0017] In some embodiments of the present invention, α1 satisfies: 45°<α1≤55°; and / or, α2 satisfies: 55°<α2<90°.

[0018] In some embodiments of the present invention, the second air guide plate includes a plate body and a rotating arm. One end of the rotating arm is rotatably connected to the housing, and the other end is fixedly connected to one side of the plate body in the thickness direction. In the off state, on a cross-section perpendicular to the length direction of the first air guide plate, the line connecting the rotation axis of the rotating arm and the housing and the connection point of the rotating arm and the plate body is a second line. In the first windless mode, on a cross-section perpendicular to the length direction of the first air guide plate, the angle between the rotation axis of the rotating arm and the housing and the connection point of the rotating arm and the plate body and the second line is β1. In the second windless mode, on a cross-section perpendicular to the length direction of the first air guide plate, the angle between the rotation axis of the rotating arm and the housing and the connection point of the rotating arm and the plate body and the second line is β2, and satisfies: β2 > β1.

[0019] In some embodiments of the present invention, β1 satisfies: 45°<β1≤53°; and / or, β2 satisfies: 53°<β2<90°.

[0020] In some embodiments of the present invention, in the cooling mode, the second air guide plate is located below the air outlet. On the cross section perpendicular to the length direction of the first air guide plate, the angle between the rotation axis of the rotating arm and the housing and the line connecting the rotating arm and the plate body and the second connecting line is β3, and satisfies: 90°≤β3≤100°.

[0021] According to some embodiments of the present invention, the control method further includes: determining that the air conditioner operates in the first windless mode for a preset time; controlling the air conditioner to operate in the second windless mode; and / or determining that the air conditioner operates in the second windless mode for a preset time; controlling the air conditioner to operate in the first windless mode.

[0022] In some embodiments of the present invention, the preset time is t, and satisfies 50min≤t≤70min.

[0023] An air conditioner according to an embodiment of the present invention includes: a housing and an air guide plate assembly. The air conditioner operates according to the control method of the air conditioner described above. The housing has an air outlet that extends horizontally. The air guide plate assembly includes a first air guide plate and a second air guide plate. The first air guide plate is movably disposed at the air outlet to open or close the air outlet. When the first air guide plate opens the air outlet, the upper end of the first air guide plate flips downward, and the lower end of the first air guide plate first descends and then flips upward. The second air guide plate is movably disposed at the air outlet. When the second air guide plate opens the air outlet, the upper end of the second air guide plate rotates downward. At least one of the first air guide plate and the second air guide plate has a plurality of spaced-apart micropores.

[0024] According to an embodiment of the present invention, when the air conditioner is in a windless mode, it can operate in either a first windless mode or a second windless mode based on the acquired indoor ambient temperature. The cooling capacity of the air conditioner in the second windless mode is greater than that in the first windless mode. This allows for windless airflow when the user does not wish to experience drafts. The air conditioner automatically switches between windless operating modes based on the indoor ambient temperature, automatically increasing the cooling capacity when the room temperature is high. This ensures both a windless effect and effective cooling, eliminating the need for manual adjustment and control when the user experiences discomfort. This enhances the intelligence and automation of the air conditioner, thereby improving user comfort and experience.

[0025] In some embodiments of the present invention, the air guide plate assembly further includes: a first rod and a second rod, one end of the first rod being rotatably connected to the housing and the other end being rotatably connected to the first air guide plate; one end of the second rod being rotatably connected to the housing and the other end being rotatably connected to the first air guide plate, the second rod being located above the first rod and spaced apart from the first rod in the vertical direction.

[0026] In some embodiments of the present invention, the second air guide plate includes: a plate body and a rotating arm, one end of the rotating arm being rotatably connected to the housing, and the other end being fixedly connected to one side of the plate body in the thickness direction.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] The control method of an air conditioner 200 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0054] like Figure 8 As shown, the control method of an air conditioner 200 according to an embodiment of the present invention includes:

[0055] Confirm that the air conditioner is in cooling mode (200).

[0056] Confirm that the air conditioner is in windless mode (200).

[0057] Obtain the indoor ambient temperature where the air conditioner 200 is located;

[0058] The air conditioner 200 is controlled to operate in either a first windless mode or a second windless mode based on the indoor ambient temperature. The cooling capacity of the air conditioner 200 in the second windless mode is greater than that in the first windless mode.

[0059] Specifically, such as Figures 1-5 As shown, the air conditioner 200 includes a housing 7 and an air guide plate assembly 100. The housing 7 has an air outlet 71 that extends horizontally. The housing 7 forms the overall appearance of the air conditioner 200. An air duct 72 is formed inside the housing 7, and the air outlet 71 communicates with the air duct 72. The top of the housing 7 may also have an air inlet 73 that communicates with the air duct 72 to allow airflow to enter the air duct 72 through the air inlet 73.

[0060] The casing 7 also includes a heat exchanger 8, a cross-flow fan 9, and louvers 10. In the airflow direction within the duct 72, the heat exchanger 8 is upstream of the cross-flow fan 9, and the louvers 10 are downstream of the cross-flow fan 9, near the air outlet 71. The heat exchanger 8 exchanges heat with the airflow flowing over its surface, the cross-flow fan 9 drives the airflow from the air inlet 73 to the air outlet 71, the first guide plate 3 and the second guide plate 6 can vertically adjust the airflow angle at the air outlet 71, and the louvers 10 can horizontally adjust the airflow angle within the duct 72.

[0061] During the specific operation of the air conditioner 200, driven by the cross-flow fan 9, outside air enters the air duct 72 inside the casing 7 from the air inlet 73. After heat exchange by the heat exchanger 8, the heat-exchanged air flows out of the air conditioner 200 from the air outlet 71 under the guidance of the louvers 10, the second air guide plate 6 and the first air guide plate 3, so as to ensure the cooling, heating and air supply functions of the air conditioner 200.

[0062] The air guide plate assembly 100 includes a first air guide plate 3 and a second air guide plate 6. The first air guide plate 3 and the second air guide plate 6 are movably disposed at the air outlet 71 to open or close the air outlet 71. When the first air guide plate 3 opens the air outlet 71, the upper end of the first air guide plate 3 flips downward and the lower end of the first air guide plate 3 first descends and then flips upward. When the second air guide plate 6 opens the air outlet 71, the upper end of the second air guide plate 6 rotates downward.

[0063] It should be noted that when the first air guide plate 3 closes the air outlet 71, the end of the first air guide plate 3 near the upper side wall of the air outlet 71 is the upper end of the first air guide plate 3, and the end of the first air guide plate 3 near the lower side wall of the air outlet 71 is the lower end of the first air guide plate 3. Similarly, when the second air guide plate 6 closes the air outlet 71, the end of the second air guide plate 6 near the upper side wall of the air outlet 71 is the upper end of the second air guide plate 6, and the end of the second air guide plate 6 near the lower side wall of the air outlet 71 is the lower end of the second air guide plate 6.

[0064] Understandably, the first air guide plate 3 can rotate according to a predetermined trajectory to open or close the air outlet 71, enabling it to close the air outlet 71 and guide airflow from the air outlet 71 at different angles. The second air guide plate 6 can rotate to change the airflow direction, directing the airflow from the air outlet 71 of the air conditioner 200 in different directions. The first air guide plate 3 and the second air guide plate 6 work together to achieve the function and effect of air outlets from the air conditioner 200 at different angles, thus enabling different air supply states of the air conditioner 200, enriching the air outlet effect, meeting diverse user needs, and improving user comfort and experience. The upper end of the second air guide plate 6 rotates downwards to the outside or below the air outlet 71, facilitating the lower end of the first air guide plate 3 to first descend and then rotate upwards to open the air outlet 71. At the same time, it can work with the first air guide plate 3 to guide the airflow to form different air supply effects of the air conditioner 200. It can also reduce the wind resistance generated by the second air guide plate 6 in the air duct 72, thereby increasing the air volume and improving the cooling, heating or air supply effect of the air conditioner 200.

[0065] For example, such as Figure 5 As shown, the upper end of the first air guide plate 3 flips downward, and the lower end first descends and then flips upward to open the air outlet 71. At this time, the air inlet end of the first air guide plate 3 is spaced apart from the two ends of the air outlet 71 in the width direction. The first air guide plate 3 is tilted in the direction away from the air outlet 71 from top to bottom. At the same time, the second air guide plate 6 rotates to the lower part of the air outlet 71 and is tilted in the direction away from the air outlet 71 from top to bottom. At this time, the second air guide plate 6 can fully open the air outlet 71 without interfering with the airflow from the air outlet 71. It can also reduce the wind resistance in the air duct 72 to ensure the air volume of the air outlet 71. Both surfaces of the first air guide plate 3 in the thickness direction are air guiding surfaces. The first air guide plate 3 can be an extension of the air duct 72, so that the flow direction of the airflow from the air outlet 71 is roughly the same as the extension direction of the air duct 72. The airflow can be smoothly blown out of the air outlet 71 under the guidance of the first air guide plate 3 through the air duct 72, which can realize the cooling mode of the air conditioner 200, ensure the air output of the air conditioner 200, and thus achieve good circulation of cold air in the room.

[0066] In addition, in cooling mode, the air conditioner 200 has the air inlet end of the first air guide plate 3 and the air outlet 71 spaced apart in the width direction. The air outlet end of the first air guide plate 3 can also swing back and forth between the two positions above and below the air inlet end of the first air guide plate 3, which can realize the back and forth air sweeping of the first air guide plate 3 in the vertical direction. At this time, both sides of the thickness direction of the first air guide plate 3 are guided, and the airflow can flow out from the air outlet 71 at different angles in the vertical direction, ensuring the vertical sweeping and air delivery state of the air conditioner 200, thereby enhancing the circulation effect of cold air in the room and improving the cooling efficiency of the air conditioner 200.

[0067] Furthermore, at least one of the first air guide plate 3 and the second air guide plate 6 is provided with a plurality of spaced-apart micro-holes 31. When the airflow passes through the first air guide plate 3 or the second air guide plate 6 provided with micro-holes 31, the micro-holes 31 can disperse and refine the airflow, making the airflow more uniform, delicate and gentle, which is conducive to achieving the windless air outlet effect of the air conditioner 200 and improving the user experience.

[0068] It should be noted that the cross-sectional shape of the micro-hole 31 can be circular, polygonal, or a strip-shaped hole (slit), etc., and the specific shape is not limited here. For example, as shown in Figures 1 and 2, the cross-section of the micro-hole 31 is circular, which has a simple structure and is easy to process. Furthermore, when multiple micro-holes 31 are provided on the first air guide plate 3, the multiple micro-holes 31 can be arranged in an array on the first air guide plate 3. This allows for the arrangement of as many micro-holes 31 as possible on the first air guide plate 3 while ensuring a certain structural strength. This ensures sufficient airflow without affecting the airflow dispersion of the first air guide plate 3, thereby ensuring the airflow of the air outlet 71. Of course, multiple micro-holes 31 can also be provided only on the second air guide plate 6, or multiple micro-holes 31 can be provided on both the first air guide plate 3 and the second air guide plate 6.

[0069] It should be noted that the air outlet 71 can be elongated and extend horizontally. The elongated shape of the air outlet 71 increases the air volume and air delivery range. In this case, the first air guide plate 3 and the second air guide plate 6 extend horizontally and are elongated, allowing them to fit with the air outlet 71 and facilitating the opening or closing of the air outlet 71. Simultaneously, the rotation axis of the second air guide plate 6 can extend horizontally, facilitating the upward and downward airflow guidance at the air outlet 71.

[0070] In this application, the air conditioner 200 may be equipped with a processor and a remote control. The processor is communicatively connected to the remote control, and the user can select different operating modes via buttons on the remote control, such as cooling mode, heating mode, or fanless mode. For example, when the user selects the cooling mode button on the remote control, the processor receives a signal from the remote control, thereby determining to activate the cooling mode.

[0071] Preferably, the air conditioner 200 may also be equipped with a voice sensor for receiving user voice commands. The processor is connected to the voice sensor. For example, the user can directly communicate the need to turn on the cooling mode via voice. The voice sensor will send a signal to the processor, thereby determining to turn on the cooling mode.

[0072] Furthermore, the air conditioner 200 is equipped with a controller, which is connected to the processor. The processor can obtain the operating mode of the air conditioner 200 required by the user through a remote control or voice sensor, and transmit the signal to the controller. The controller then sends control signals to control the movement of the first air guide plate 3 and the second air guide plate 6, thereby adjusting the air delivery angle of the air conditioner 200.

[0073] For example, when a user selects the cooling mode via remote control or voice, the processor receives the instruction from the air conditioner 200 to activate the cooling mode. It then sends the parsed signal to the controller. Based on the received signal, the controller controls the upper end of the second air guide plate 6 to rotate downwards to open the air outlet 71. Simultaneously, it controls the upper end of the first air guide plate 3 to flip downwards and the lower end of the first air guide plate 3 to first descend and then flip upwards to open the air outlet 71. This causes the first air guide plate 3 to tilt downwards in a direction away from the air outlet 71, with the air outlet located below or slightly below the air inlet. The second air guide plate 6 rotates to a position below the air outlet 71. At this point, both the inner and outer surfaces of the first air guide plate 3 act as air guiding surfaces. This allows the first air guide plate 3 to become an extension of the air duct 72, enabling smooth airflow from the air outlet 71 in a direction roughly the same as the extension direction of the air duct 72. This ensures sufficient airflow from the air conditioner 200, achieving good circulation of cool air indoors and improving the cooling efficiency of the air conditioner 200.

[0074] Furthermore, such as Figure 3 and Figure 4 As shown, the air conditioner 200 may be equipped with a temperature sensor to determine the indoor ambient temperature where the air conditioner 200 is located. The temperature sensor is communicatively connected to the processor, and the temperature sensor transmits the measured temperature signal to the processor in real time. When the user selects the windless mode via remote control or voice, after receiving the instruction from the air conditioner 200 to activate the windless mode, the processor will determine whether to operate the first windless mode or the second windless mode based on the received indoor ambient temperature. Then, it will send the parsed signal to the controller. The controller will then control the distance and angle of the movement of the first air guide plate 3 and the second air guide plate 6 according to the received signal, thereby selectively achieving the first windless mode or the second windless mode, which can prevent cold air from blowing directly on the user and ensure the user's comfort.

[0075] In this mode, the cooling capacity of air conditioner 200 in the second windless mode is greater than that in the first windless mode. When air conditioner 200 enters windless mode, the airflow and speed decrease significantly to prevent cold air from blowing directly on the user. However, the cooling capacity also decreases compared to the cooling mode, leading to a rise in indoor temperature and causing discomfort for the user. Through the above control method, air conditioner 200 can automatically detect the indoor temperature in real time and automatically select either the first or second windless mode based on the specific indoor temperature. When the indoor temperature is low, air conditioner 200 selects to operate in the first windless mode, where the cooling capacity does not need to be too high, just enough to maintain the windless effect. When the indoor temperature is high, air conditioner 200 automatically switches to the second windless mode, where the cooling capacity increases, improving the cooling effect. This maintains the windless effect while lowering the indoor temperature, thereby further improving user comfort and experience.

[0076] Furthermore, by setting the above control method, when the air conditioner 200 is turned on in windless mode, it can automatically switch between the first windless mode and the second windless mode according to the indoor ambient temperature. This eliminates the need for users to manually adjust and control the air conditioner when they feel uncomfortable, thereby improving the intelligence and automation of the air conditioner 200 and further enhancing the user's convenience and experience.

[0077] According to the control method of the air conditioner 200 of the present invention, when the air conditioner 200 is in a windless mode, it can operate either a first windless mode or a second windless mode based on the acquired indoor ambient temperature. The cooling capacity of the air conditioner 200 in the second windless mode is greater than that in the first windless mode. This allows the air conditioner 200 to achieve a windless airflow effect when the user does not want drafts. It also automatically switches between windless operating modes based on the indoor ambient temperature, automatically increasing the cooling capacity of the air conditioner 200 when the room temperature is high. This ensures both a windless effect and effective cooling, eliminating the need for manual adjustment and control when the user feels uncomfortable. This improves the intelligence and automation of the air conditioner 200, thereby enhancing user comfort and experience.

[0078] In some embodiments of the present invention, such as Figure 8 As shown, determining whether the air conditioner 200 operates in the first or second windless mode based on the indoor ambient temperature includes:

[0079] When the indoor ambient temperature is less than or equal to the preset temperature value, the air conditioner 200 will activate the first windless mode.

[0080] When the indoor ambient temperature is higher than the preset temperature value, the air conditioner 200 is set to activate the second windless mode.

[0081] Understandably, the temperature sensor is connected to the processor, and the sensor transmits the measured temperature signal to the processor in real time. When the processor determines that the indoor ambient temperature is less than or equal to the preset temperature value, it sends a signal to the controller to activate the first windless mode. Upon receiving the signal from the processor, the controller controls the first air guide plate 3 and the second air guide plate 6 to move at corresponding angles and distances to achieve the first windless mode of the air conditioner 200. This ensures a windless effect, prevents cold air from blowing directly on the user, and thus improves the user's comfort and experience.

[0082] Similarly, when the processor determines that the indoor ambient temperature is greater than the preset temperature value, the processor will send a signal to the controller to activate the second windless mode. After receiving the signal from the processor, the controller controls the first air guide plate 3 and the second air guide plate 6 to move at the corresponding angle and distance to realize the second windless mode of the air conditioner 200. At this time, the air conditioner 200 automatically increases the cooling capacity due to the increase in indoor temperature, thereby improving the cooling effect and reducing the indoor ambient temperature, taking into account both the windless effect and the cooling effect, thereby improving the user's comfort and experience.

[0083] By setting the above control method, when the air conditioner 200 is turned on in windless mode, it can automatically switch between the first windless mode and the second windless mode according to the indoor ambient temperature. Users do not need to manually adjust and control it when they feel uncomfortable. This can improve the intelligence and automation control of the air conditioner 200, and further improve the user's convenience and user experience.

[0084] The preset temperature value is a value pre-stored in the memory of the air conditioner 200, which is obtained through experimental testing by technicians. The preset temperature value can specifically be 26℃. Of course, the preset temperature value can be specifically set according to the geographical location and environmental characteristics of the air conditioner 200; this application does not impose any specific limitations on this.

[0085] In some embodiments of the present invention, such as Figure 8 As shown, obtaining the indoor ambient temperature where the air conditioner 200 is located includes:

[0086] The return air temperature at the return air vent of the air conditioner 200 is obtained as the indoor ambient temperature.

[0087] Understandably, since the temperature sensor is a component of the air conditioner 200, it is not convenient to install it indoors. Therefore, the temperature sensor can be fixed on the housing 7 and located at the return air vent of the air conditioner 200 to detect the temperature of the indoor return air at the return air vent, and use this temperature as the indoor ambient temperature. This can ensure the accuracy of the detected temperature and reduce the difficulty of communication between the temperature sensor and the processor.

[0088] In some embodiments of the present invention, such as Figure 8 As shown, in the first windless mode, the indoor fan of the air conditioner 200 operates at the first speed; in the second windless mode, the indoor fan of the air conditioner 200 operates at the second speed; and in the cooling mode, the indoor fan of the air conditioner 200 operates at the third speed. The first speed, the second speed, and the third speed are n1, n2, and n3, respectively, and satisfy: n1 < n2 ≤ n3.

[0089] It is understandable that the air conditioner 200 may be equipped with an electrical control box, which is connected to the processor. The processor can obtain the operating mode of the air conditioner 200 required by the user through a remote control or voice sensor, and transmit the signal to the electrical control box. The electrical control box then sends an electrical control signal to control the speed of the indoor fan of the air conditioner 200.

[0090] When a user selects the cooling mode via remote control or voice command, the processor receives the instruction from the air conditioner 200 to activate the cooling mode. It then sends the analyzed signal to the control box, which in turn controls the indoor fan of the air conditioner 200 to operate at the third speed to ensure adequate airflow and speed at the air outlet 71, thereby guaranteeing the cooling effect. Similarly, when the user needs to activate the draftless mode, the control box will control the indoor fan to operate at either the first or second speed.

[0091] In the cooling mode, where n1 < n2 ≤ n3, the air conditioner 200 needs to maintain both airflow and cooling efficiency. Therefore, the indoor fan speed needs to be higher to meet user needs. In the windless mode, users do not require drafts, so the indoor fan speed is reduced to ensure a windless effect and prevent users from feeling drafts. However, when the indoor temperature is high, the air conditioner 200 automatically activates a second windless mode. In this mode, the cooling capacity needs to be increased, so n1 < n2. This effectively improves the cooling efficiency of the second windless mode to prevent users from overheating.

[0092] In some embodiments of the present invention, such as Figure 8As shown, n1 satisfies: 775 r / min ≤ n1 ≤ 925 r / min. If n1 is less than 775 r / min, the indoor fan speed is too low, resulting in insufficient airflow from the air conditioner 200 and failing to guarantee its cooling effect. If n1 is greater than 925 r / min, the indoor fan speed is too high, reducing the windless effect and increasing energy consumption. Therefore, ensuring 775 r / min ≤ n1 ≤ 925 r / min improves the windless effect in the first windless mode, guarantees the cooling effect, and avoids excessive energy consumption by the air conditioner 200.

[0093] In some embodiments of the present invention, such as Figure 8 As shown, n2 satisfies: 1000r / min ≤ n2 ≤ 1500r / min. If n2 is less than 1000r / min, the indoor fan speed is too low, resulting in insufficient airflow from the air conditioner 200, which cannot guarantee the increased cooling capacity in the second windless mode. If n2 is greater than 1500r / min, the indoor fan speed is too high, which will reduce the windless effect and increase energy consumption. Therefore, ensuring 1000r / min ≤ n2 ≤ 1500r / min guarantees the windless effect in the second windless mode, improves the cooling effect, and avoids excessive energy consumption by the air conditioner 200.

[0094] In some embodiments of the present invention, such as Figure 8 As shown, n3 satisfies the condition: 1000 r / min ≤ n3 ≤ 1500 r / min. If n3 is less than 1000 r / min, the indoor fan speed is too low, resulting in insufficient airflow from the air conditioner 200 and failing to guarantee its cooling effect. If n3 is greater than 1500 r / min, the indoor fan speed is too high, increasing energy consumption. Therefore, ensuring 1000 r / min ≤ n3 ≤ 1500 r / min guarantees the cooling effect in cooling mode while preventing excessive energy consumption by the air conditioner 200.

[0095] In some embodiments of the present invention, such as Figure 8 As shown, in the first windless mode, the compressor of the air conditioner 200 operates at the first frequency; in the second windless mode, the compressor of the air conditioner 200 operates at the second frequency; and in the cooling mode, the compressor of the air conditioner 200 operates at the third frequency. The first frequency, the second frequency, and the third frequency are f1, f2, and f3, respectively, and satisfy: f1 < f2 < f3.

[0096] It is understandable that the air conditioner 200 may be equipped with an electrical control box, which is connected to the processor. The processor can obtain the operating mode of the air conditioner 200 required by the user through a remote control or voice sensor, and transmit the signal to the electrical control box. The electrical control box then sends an electrical control signal to control the frequency of the compressor in the outdoor unit of the air conditioner 200.

[0097] When a user selects a cooling mode via remote control or voice command, the processor receives the instruction from the air conditioner 200 to activate the cooling mode. It then sends the analyzed signal to the control box, which in turn controls the compressor of the air conditioner 200 to operate at a third frequency to ensure sufficient cooling capacity and thus maintain the cooling effect. Similarly, when the user needs to activate the fanless mode, the control box will control the compressor to operate at either the first or second frequency.

[0098] In the cooling mode, f1 < f2 < f3. To ensure the cooling effect of air conditioner 200, the compressor needs to operate at a higher frequency to meet user needs. In the windless mode, users do not want to feel cold air, so the airflow and speed from air outlet 71 are lower. Therefore, the compressor frequency can be reduced accordingly to avoid excessive energy consumption. However, when the indoor temperature is high, air conditioner 200 automatically activates the second windless mode. In this case, the cooling capacity needs to be increased, so f1 < f2. This effectively improves the cooling efficiency of the second windless mode, thereby effectively reducing the indoor temperature and preventing users from overheating.

[0099] In some embodiments of the present invention, such as Figure 8 As shown, f1 satisfies: 25Hz ≤ f1 ≤ 35Hz. If f1 is less than 25Hz, the compressor frequency is too low, resulting in insufficient cooling capacity of the air conditioner 200 and failing to guarantee its cooling effect. If f1 is greater than 35Hz, the compressor frequency is too high, increasing energy consumption. Therefore, ensuring 25Hz ≤ f1 ≤ 35Hz improves the windless effect in the first windless mode, guarantees the cooling effect, and avoids excessive energy consumption by the air conditioner 200.

[0100] In some embodiments of the present invention, such as Figure 8 As shown, f2 satisfies: 35Hz < f2 ≤ 45Hz. If f2 is less than or equal to 35Hz, the compressor frequency is too low, resulting in insufficient cooling capacity of air conditioner 200, which cannot meet the increased cooling capacity requirement of the second windless mode. If f2 is greater than 45Hz, the compressor frequency is too high, increasing energy consumption. Therefore, ensuring 35Hz < f2 ≤ 45Hz guarantees the windless effect in the second windless mode, improves cooling efficiency, and avoids excessive energy consumption of air conditioner 200.

[0101] In some embodiments of the present invention, such as Figure 8 As shown, f3 satisfies the condition: f3 > 70Hz. If f3 is less than or equal to 70Hz, the compressor frequency is too low, resulting in insufficient cooling capacity of the air conditioner 200 and failing to guarantee its cooling effect. Therefore, ensuring f3 > 70Hz guarantees the cooling effect in cooling mode to meet the user's cooling needs.

[0102] In some embodiments of the present invention, such as Figure 3 , Figure 4 and Figure 8 As shown, in the first windless mode and the second windless mode, the first air guide plate 3 opens the air outlet 71 from the bottom, and the second air guide plate 6 rotates to the outside of the air outlet 71, with the air outlet end of the first air guide plate 3 abutting against the air outlet end of the second air guide plate 6.

[0103] In the first windless mode, the distance between the upper end of the first air guide plate 3 in the width direction and the upper end of the air outlet 71 in the width direction along the vertical direction is h1.

[0104] In the second windless mode, the distance between the upper end of the width direction of the first air guide plate 3 and the upper end of the width direction of the air outlet 71 along the vertical direction is h2, and h2 > h1.

[0105] Understandably, in both the first and second windless modes, the first air guide plate 3 is generally vertically positioned, and the second air guide plate 6 is generally horizontally positioned. The air outlet end of the second air guide plate 6 abuts against the air outlet end of the first air guide plate 3, so that at least a portion of the air outlet 71 is confined between the first air guide plate 3 and the second air guide plate 6. An air duct 72 communicating with the air outlet 71 is formed inside the housing 7. The airflow flows from the air duct 72 to the air outlet 71 and passes through the micro-holes 31 on the first air guide plate 3 and / or the second air guide plate 6 and blows into the room. The airflow is dispersed by the micro-holes 31 and forms an airflow dispersion, which can improve the turbulence state during the airflow process, reduce the airflow velocity, and improve the smoothness of the airflow. This ensures that the airflow does not blow directly onto the user after it is blown out of the air outlet 71, thus achieving the windless airflow effect of the air conditioner 200 and improving the user's comfort and experience.

[0106] The upper end of the first air guide plate 3 is spaced apart from the upper edge of the air outlet 71. An air duct 72, communicating with the air outlet 71, is formed inside the housing 7. A small amount of airflow within the air duct 72 can be blown into the room through the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71. The airflow direction is mostly upward or horizontal, resulting in a longer flow distance and preventing direct downward blowing towards the user. This ensures a windless airflow effect while increasing the air volume of the air outlet 71, thereby improving the cooling effect of the air conditioner 200 in the windless state. Furthermore, h2 > h1, meaning that in the second windless mode, the airflow from the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 travels a longer distance and has a larger flow rate, further improving the cooling effect in the second windless state. It also effectively solves the problem of low near-field temperatures and high far-field temperatures in the air conditioner 200 in the windless mode, thus actively adjusting and improving the uniformity of the indoor temperature, thereby enhancing user comfort.

[0107] In some embodiments of the present invention, such as Figure 3 As shown, h1 satisfies the condition: 5mm < h1 ≤ 15mm. If h1 is less than or equal to 5mm, the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 is too small, which cannot guarantee the airflow of the air conditioner 200, resulting in poor cooling effect. If h1 is greater than 15mm, the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 is too large, which will reduce the windless effect. Therefore, 5mm < h1 ≤ 15mm can both improve the windless airflow effect in the first windless mode and ensure the cooling effect.

[0108] In some embodiments of the present invention, such as Figure 4 As shown, h2 satisfies the condition: 15mm < h2 < 30mm. If h2 is less than or equal to 15mm, the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 is too small, which cannot guarantee the airflow of the air conditioner 200, resulting in a poor effect in improving cooling capacity. If h2 is greater than or equal to 30mm, the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 is too large, which will cause the windless effect to fail. Therefore, 15mm < h2 < 30mm ensures both a windless airflow effect in the second windless mode and an improved cooling effect, thereby enhancing user comfort.

[0109] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, when the air conditioner 200 is off, the first air guide plate 3 closes the air outlet 71, and the second air guide plate 6 is located outside the first air guide plate 3 and is stacked with it. At this time, the first air guide plate 3 and the second air guide plate 6 together close the air outlet 71, and together with the housing 7, they form the complete appearance of the air conditioner 200, which can improve the aesthetics of the air conditioner 200. At the same time, the stacked first air guide plate 3 and the second air guide plate 6 can form a tighter sealing structure, which can improve the dust prevention effect and thus improve the cleanliness of the inside of the air conditioner 200.

[0110] When the air conditioner 200 is off, the first air guide plate 3 closes the upper part of the air outlet 71, and the second air guide plate 6 closes the lower part of the air outlet 71. The upper end of the second air guide plate 6 and the lower end of the first air guide plate 3 are stacked together. The first air guide plate 3 and the second air guide plate 6 cooperate with each other to completely block the air outlet 71.

[0111] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the air guide plate assembly 100 also includes a first rod 1 and a second rod 2. One end of the first rod 1 is rotatably connected to the housing 7, and the other end is rotatably connected to the first air guide plate 3. One end of the second rod 2 is rotatably connected to the housing 7, and the other end is rotatably connected to the first air guide plate 3. The second rod 2 is located above the first rod 1 and is spaced apart from the first rod 1 in the vertical direction. When the air conditioner 200 is in the off state, on a cross-section perpendicular to the length direction of the first air guide plate 3, the line connecting the rotation axes of the two ends of the second rod 2 in the length direction is the first connecting line.

[0112] In the first windless mode, on a cross-section perpendicular to the length of the first air guide plate 3, the angle between the line connecting the rotation axes of the two ends of the second rod 2 along its length and the first connecting line is α1.

[0113] In the second windless mode, on the cross section perpendicular to the length direction of the first air guide plate 3, the angle between the line connecting the rotation axes of the two ends of the second rod 2 along the length direction and the first connecting line is α2, and satisfies: α2>α1.

[0114] The phrase "the second rod 2 is located above the first rod 1" can be understood as follows: the end of the second rod 2 that is rotatably connected to the housing 7 is located above the end of the first rod 1 that is rotatably connected to the housing 7. The phrase "the first rod 1 is spaced apart in the vertical direction" can be understood as follows: the end of the second rod 2 that is rotatably connected to the housing 7 is spaced apart from the end of the first rod 1 that is rotatably connected to the housing 7 in the vertical direction.

[0115] It is understandable that the housing 7, the first rod 1, the second rod 2, and the first air guide plate 3 can form a four-bar linkage mechanism. The first air guide plate 3 is the driven component in the four-bar linkage mechanism. The connection point where one end of the first rod 1 and the second rod 2 is rotatably connected to the housing 7 can serve as a fulcrum. Through the rotation of the first rod 1 and the second rod 2, the motion is transmitted to the first air guide plate 3, so that the motion of the first air guide plate 3 is no longer a simple linear or circular motion, but rather it rotates according to a predetermined trajectory to complete the action of opening or closing the air outlet 71. The design structure of the above four-bar linkage mechanism is simple and low in cost, and it can make the motion trajectory of the first air guide plate 3 more precise and controllable.

[0116] For example, the air guide plate assembly 100 may further include a first drive assembly 4, which is mounted on the housing 7. The end of the second rod 2 facing away from the first air guide plate 3 is connected to the first drive assembly 4 to drive the second rod 2 to rotate. The controller of the air conditioner 200 can communicate with the first drive assembly 4. When the user selects the desired operating mode via remote control or voice, the processor receives the instruction for the desired operating mode from the air conditioner 200, parses the instruction, and determines the operating parameters of the first drive assembly 4, such as the rotation angle and direction of the motor output shaft. The processor then transmits the operating parameter signals to the controller, causing the controller to send a control signal to the first drive assembly 4 to control the rotation of the second rod 2.

[0117] Furthermore, α2 > α1, meaning that compared to the first windless mode, in the second windless mode, the second lever 2 rotates at a larger angle than in the off state. This results in a larger gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 in the second windless mode. Consequently, the airflow blowing into the room from the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 travels a longer distance and has a larger airflow rate. This further improves the cooling effect in the second windless state and effectively solves the problem of low temperature near the air conditioner and high temperature far away in the windless mode. This allows for active adjustment and improvement of the uniformity of the indoor temperature, thereby enhancing user comfort.

[0118] In some embodiments of the present invention, such as Figure 3 As shown, α1 satisfies the condition: 45°<α1≤55°. If α1 is less than or equal to 45°, the rotation angle of the second rod 2 is too small, and the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 is too small, which cannot guarantee the airflow of the air conditioner 200, resulting in poor cooling effect. If α1 is greater than 55°, the rotation angle of the second rod 2 is too large, and the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 is too large, which will reduce the windless effect. Therefore, 45°<α1≤55° can improve the windless airflow effect in the first windless mode while ensuring the cooling effect.

[0119] In some embodiments of the present invention, such as Figure 4 As shown, α2 satisfies the condition: 55° < α2 < 90°. If α2 is less than or equal to 55°, the rotation angle of the second rod 2 is too small, and the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 is too small, which cannot guarantee the airflow of the air conditioner 200, resulting in a poor effect in improving cooling capacity. If α2 is greater than or equal to 90°, the rotation angle of the second rod 2 is too large, and the gap between the upper end of the first air guide plate 3 and the upper edge of the air outlet 71 is too large, which will cause the windless effect to fail. Therefore, 55° < α2 < 90° is required to ensure the windless airflow effect in the second windless mode while improving the cooling effect, thereby enhancing user comfort.

[0120] In some embodiments of the present invention, the second air guide plate 6 includes a plate body 61 and a rotating arm 62. One end of the rotating arm 62 is rotatably connected to the housing 7, and the other end is fixedly connected to one side of the plate body 61 in the thickness direction. When the air conditioner 200 is in the off state, on a cross-section perpendicular to the length direction of the first air guide plate 3, the line connecting the rotation axis of the rotating arm 62 and the housing 7 and the connection point of the rotating arm 62 and the plate body 61 is a second connecting line.

[0121] In the first windless mode, on a cross-section perpendicular to the length of the first air guide plate 3, the angle between the rotation axis of the rotating arm 62 and the housing 7 and the line connecting the rotating arm 62 and the plate body 61 and the second connecting line is β1.

[0122] In the second windless mode, on the cross section perpendicular to the length direction of the first air guide plate 3, the angle between the rotation axis of the rotating arm 62 and the housing 7 and the line connecting the rotating arm 62 and the plate body 61 and the second connecting line is β2, and satisfies: β2>β1.

[0123] It is understandable that the rotating arm 62 and the housing 7 can be rotatably connected through the shaft hole. By setting the rotating arm 62, the rotation of the second air guide plate 6 at the air outlet 71 can be facilitated. The rotating arms 62 are multiple and spaced apart along the length of the second air guide plate 6, so that the force on the second air guide plate 6 can be distributed and more evenly, which helps to improve the reliability and stability of the rotation of the second air guide plate 6.

[0124] For example, the air guide plate assembly 100 may further include a second drive assembly 5, which is mounted on the housing 7 and connected to the second air guide plate 6 to drive the second air guide plate 6 to rotate. The controller of the air conditioner 200 can communicate with the second drive assembly 5. When the user selects the desired operating mode via remote control or voice, the processor receives the instruction for the desired operating mode from the air conditioner 200, parses the instruction, and determines the operating parameters of the second drive assembly 5, such as the rotation angle and direction of the motor output shaft. The processor then transmits the operating parameter signals to the controller, causing the controller to send control signals to the second drive assembly 5 to control the rotation of the rotating arm 62.

[0125] Furthermore, β2 > β1, meaning that compared to the first windless mode, the rotating arm 62 rotates at a greater angle in the second windless mode compared to the off state. This allows for better coordination with the movement angle of the first air guide plate 3, ensuring that the air outlets of the first air guide plate 3 and the second air guide plate 6 can overlap to guarantee the windless effect of the air conditioner 200. It also ensures improved cooling capacity in the second windless mode, demonstrating a reasonable design in terms of structure and control method.

[0126] In some embodiments of the present invention, such as Figure 3 As shown, β1 satisfies: 45°<β1≤53°; thus, in the first windless mode, the rotation angle of the second air guide plate 6 is moderate, which allows the air outlet end of the first air guide plate 3 and the air outlet end of the second air guide plate 6 to maintain overlap to ensure the windless effect of the air conditioner 200.

[0127] In some embodiments of the present invention, such as Figure 4 As shown, β2 satisfies: 53° < β2 < 90°. Thus, in the second windless mode, the rotation angle of the second air guide plate 6 is appropriate, allowing the air outlet ends of the first air guide plate 3 and the second air guide plate 6 to maintain contact, ensuring the windless effect of the air conditioner 200. At this time, the air outlet end of the first air guide plate 3 is lower than in the first windless mode, allowing the second air guide plate 6 to cooperate and ensure the cooling capacity in the second windless mode to meet user needs.

[0128] In some embodiments of the present invention, such as Figure 5 As shown, in cooling mode, the second air guide plate 6 is located below the air outlet 71. On the cross-section perpendicular to the length direction of the first air guide plate 3, the angle between the rotation axis of the rotating arm 62 and the housing 7 and the line connecting the rotating arm 62 and the plate body 61 and the second connecting line is β3, and satisfies: 90°≤β3≤100°.

[0129] Understandably, in cooling mode, with 90°≤β3≤100°, meaning the second air guide plate 6 rotates downwards around the rotation axis located at the lower end of the air outlet 71 to below the air outlet 71 and tilts downwards in the direction away from the air outlet 71, the air outlet 71 can be fully opened, avoiding interference with the airflow exiting from the air outlet 71. The second air guide plate 6, located below the air outlet 71, also reduces wind resistance within the air duct 72, ensuring sufficient airflow from the air outlet 71. Airflow can then smoothly exit from the air outlet 71, thus ensuring sufficient airflow from the air conditioner 200, achieving good circulation of cool air indoors, and improving the cooling efficiency of the air conditioner 200.

[0130] In some embodiments of the present invention, such as Figure 8 As shown, the control method also includes:

[0131] Determine that the air conditioner 200 operates in the first windless mode for the preset time;

[0132] Control the air conditioner 200 to run in the second windless mode;

[0133] And / or, determine that the air conditioner 200 operates in the second windless mode for a preset time;

[0134] Control the air conditioner to run in the first windless mode.

[0135] Understandably, the air conditioner 200 may be equipped with a timer to measure the duration of operation of the air conditioner 200 in either the first or second windless mode. The timer is communicatively connected to the processor, transmitting the measured time signal to the processor, which then determines whether to switch modes and sends a signal to the controller based on the determination result.

[0136] When the air conditioner 200 operates in the first windless mode for a preset time, the processor makes a judgment and transmits the signal to the controller to activate the second windless mode, thus switching the air conditioner 200 to the second windless mode; when the air conditioner 200 operates in the second windless mode for a preset time, the processor makes a judgment and transmits the signal to the controller to activate the first windless mode, thus switching the air conditioner 200 to the first windless mode.

[0137] The accuracy and sensitivity of the air conditioner 200 in obtaining the indoor ambient temperature are not high. Therefore, when the air conditioner 200 runs only the first windless mode or the second windless mode for a long time, the air conditioner 200 can automatically switch according to the running time, so as to ensure the cooling effect while ensuring the windless feeling, and avoid the user feeling uncomfortable and having to operate manually. This can further improve the intelligence of the air conditioner 200, thereby improving the user experience.

[0138] In some embodiments of the present invention, the preset time is t, and satisfies 50min≤t≤70min. If the preset time is too short, the mode switching will be too frequent, causing user discomfort; if the preset time is too long, it will not be able to address the problem of low accuracy and sensitivity in obtaining indoor ambient temperature by the air conditioner 200. Therefore, 50min≤t≤70min can balance the windless effect and the cooling effect, further improve the intelligence of the air conditioner 200, and enhance the user experience.

[0139] An air conditioner 200 according to an embodiment of the present invention is described below.

[0140] An air conditioner 200 according to an embodiment of the present invention includes: a housing 7 and an air guide plate assembly 100.

[0141] Specifically, such as Figures 1-5 As shown, the housing 7 has an air outlet 71 that extends horizontally. The air guide plate assembly 100 includes a first air guide plate 3 and a second air guide plate 6. The first air guide plate 3 is movably disposed at the air outlet 71 to open or close the air outlet 71. When the first air guide plate 3 opens the air outlet 71, the upper end of the first air guide plate 3 flips downward and the lower end of the first air guide plate 3 first descends and then flips upward. The second air guide plate 6 is movably disposed at the air outlet 71. When the second air guide plate 6 opens the air outlet 71, the upper end of the second air guide plate 6 rotates downward. At least one of the first air guide plate 3 and the second air guide plate 6 is provided with a plurality of spaced microholes 31.

[0142] According to an embodiment of the present invention, the air conditioner 200, when the air conditioner 200 is in a windless mode, can operate either a first windless mode or a second windless mode based on the acquired indoor ambient temperature. The cooling capacity of the air conditioner 200 in the second windless mode is greater than that in the first windless mode. This allows the air conditioner 200 to achieve a windless airflow effect when the user does not want to be exposed to drafts. It automatically switches between windless operating modes based on the indoor ambient temperature and automatically increases the cooling capacity when the room temperature is high. This ensures both a windless effect and effective cooling without requiring manual adjustment or control by the user when they feel uncomfortable. This enhances the intelligence and automation of the air conditioner 200, thereby improving user comfort and experience.

[0143] In some embodiments of the present invention, such as Figures 2-5 As shown, the air guide plate assembly 100 further includes: a first rod 1 and a second rod 2. One end of the first rod 1 is rotatably connected to the housing 7, and the other end is rotatably connected to the first air guide plate 3. One end of the second rod 2 is rotatably connected to the housing 7, and the other end is rotatably connected to the first air guide plate 3. The second rod 2 is located above the first rod 1 and is spaced apart from the first rod 1 in the vertical direction.

[0144] It is understandable that the housing 7, the first rod 1, the second rod 2, and the first air guide plate 3 can form a four-bar linkage mechanism. The first air guide plate 3 is the driven component in the four-bar linkage mechanism. The connection point where one end of the first rod 1 and the second rod 2 is rotatably connected to the housing 7 can serve as a fulcrum. Through the rotation of the first rod 1 and the second rod 2, the motion is transmitted to the first air guide plate 3, so that the motion of the first air guide plate 3 is no longer a simple linear or circular motion, but rather it rotates according to a predetermined trajectory to complete the action of opening or closing the air outlet 71. The design structure of the above four-bar linkage mechanism is simple and low in cost, and it can make the motion trajectory of the first air guide plate 3 more precise and controllable.

[0145] Meanwhile, the two ends of the first rod 1 and the second rod 2 are rotatably connected to the housing 7 and the first air guide plate 3, respectively, which can disperse the stress and impact during the movement process, making the first air guide plate 3 more stable when opening or closing the air outlet 71, thereby reducing vibration and noise and enhancing the reliability and stability of the air guide plate assembly 100. The rotation axes of the first rod 1 and the second rod 2 can extend horizontally, facilitating the closing of the air outlet 71 by the first air guide plate 3, or enabling the first air guide plate 3 to guide airflow vertically at the air outlet 71.

[0146] Furthermore, rotating the first rod 1 and the second rod 2 at different angles can drive the first air guide plate 3 to complete different angle flips and different position movements, which can increase the diversity of the air guiding mode of the first air guide plate 3. Without increasing the size of the air conditioner 200 or increasing the cost, different air supply states of the air conditioner 200 can be realized, improving the richness of the air conditioning air output effect, meeting the diverse needs of users, and thus improving the user's comfort and experience.

[0147] In addition, during the specific implementation process, the length and angle of the first rod 1 and the second rod 2 can be adjusted as needed to achieve different angles of rotation and different positions of the first air guide plate 3, thereby achieving different air guiding effects.

[0148] In some embodiments of the present invention, such as Figures 2-7 As shown, the second air guide plate 6 includes a plate body 61 and a rotating arm 62. One end of the rotating arm 62 is rotatably connected to the housing 7, and the other end is fixedly connected to one side of the plate body 61 in the thickness direction. The rotating arm 62 and the housing 7 can be rotatably connected through a shaft hole. By setting the rotating arm 62, the rotation of the second air guide plate 6 at the air outlet 71 can be facilitated. Multiple rotating arms 62 are spaced apart along the length of the second air guide plate 6, which allows the force on the second air guide plate 6 to be distributed and more evenly distributed, helping to improve the reliability and stability of the rotation of the second air guide plate 6.

[0149] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the air conditioner 200 has a windless state. In the windless state, the first air guide plate 3 opens the air outlet 71 from the bottom, and the air outlet end of the second air guide plate 6 abuts against the air outlet end of the first air guide plate 3.

[0150] Understandably, in the windless state, the first air guide plate 3 is generally vertically positioned, and the second air guide plate 6 is generally horizontally positioned, with the air outlet end of the second air guide plate 6 abutting against the air outlet end of the first air guide plate 3. This confines at least a portion of the air outlet 71 between the first air guide plate 3 and the second air guide plate 6. An air duct 72 communicating with the air outlet 71 is formed inside the housing 7. The airflow flows from the air duct 72 to the air outlet 71 and passes through the micro-holes 31 on the first air guide plate 3 and / or the second air guide plate 6, blowing into the room. The airflow is dispersed by the micro-holes 31, forming an airflow dispersion, which can improve the turbulence state during the airflow process, while reducing the airflow velocity and improving the smoothness of the airflow. This ensures that the airflow does not blow directly onto the user after being blown out of the air outlet 71, thus achieving the windless airflow effect of the air conditioner 200 and improving the user's comfort and experience.

[0151] In addition, compared with the first air guide plate 3 having micro-holes 31 and closing the air outlet 71 to achieve a windless state for the air conditioner 200, the air inlet end of the first air guide plate 3 is close to the upper end of the air outlet 71 and the first air guide plate 3 is generally vertically set, and the air outlet end of the second air guide plate 6 abuts against the air outlet end of the first air guide plate 3. This can increase the air outlet area while achieving a windless air outlet state, thereby increasing the air volume of the air outlet 71.

[0152] Furthermore, such as Figure 3 and Figure 4 As shown in the example, along the length of the air outlet 71, the length of the first air guide plate 3 and the second air guide plate 6 are the same. The two ends of the first air guide plate 3 and the second air guide plate 6 are flush along their lengths, and the widths of the first air guide plate 3 and the second air guide plate 6 are the same. Compared to setting the second air guide plate 6 to be smaller in both length and width than the first air guide plate 3, the above arrangement of the first air guide plate 3 and the second air guide plate 6 further increases the air outlet area, thereby better improving the air volume of the air outlet 71. It also prevents some airflow from flowing directly out from both ends of the second air guide plate 6 along its length, further improving the windless airflow effect. At the same time, the arrangement of the air guide plates 3 and 6 is more orderly, improving the aesthetics of the air conditioner 200 in a windless state.

[0153] In some embodiments of the present invention, such as Figure 3 and Figure 4As shown, in the windless state, the air inlet end of the first air guide plate 3 and the upper edge of the air outlet 71 are spaced apart. The interior of the housing 7 forms an air duct 72 that communicates with the air outlet 71. A small amount of airflow in the air duct 72 can be blown into the room through the gap between the air inlet end of the first air guide plate 3 and the upper edge of the air outlet 71. The flow direction is mostly upward or horizontal, resulting in a long flow distance and preventing direct downward blowing to the user. This ensures that while maintaining the windless airflow effect, the air volume of the air outlet 71 can be increased, thereby improving the cooling effect of the air conditioner 200 in the windless state.

[0154] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, in the windless state, the second air guide plate 6 is located below the air outlet 71. The interior of the housing 7 forms an air duct 72 that communicates with the air outlet 71. The airflow blowing out of the air outlet 71 and flowing downward needs to flow through the micro-holes 31 on the second air guide plate 6 and blow into the room, or flow towards the first air guide plate 3 under the guidance of the second air guide plate 6. This can prevent a small amount of airflow in the air duct 72 from blowing directly downward to the user through the gap between the end of the second air guide plate 6 near the housing 7 and the lower edge of the air outlet 71, which can improve the windless airflow effect.
