Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an air conditioner and its control method, apparatus and computer-readable storage medium. Background Technology

[0002] An air conditioner is a device used to regulate air parameters within a space. In existing technology, the air conditioner casing houses a heat exchanger and a fan system, with air inlets and outlets on the casing. The air inlets are typically located at the top or back of the casing. However, due to limitations in the internal space layout and exterior design, traditional air inlets, often located at the top or back, have a relatively fixed opening area. This makes it difficult to provide sufficient air circulation under high-load conditions requiring rapid cooling or heating, leading to increased energy consumption and prolonged compressor operating time.

[0003] However, placing the air inlet on the visible panel can easily expose internal components. Summary of the Invention

[0004] This application provides an air conditioner and its control method, device and computer-readable storage medium, aiming to solve the technical problem in the prior art where the internal components are exposed when the visible panel is opened.

[0005] In a first aspect, this application proposes a control method for an air conditioner, wherein the air conditioner has a first air inlet on a visible panel and an air guide plate on the first air inlet; the air guide plate has a leeward side and a windward side arranged opposite to each other; when the first air inlet is opened, the leeward side of the air guide plate is tilted downward to shield the internal components of the air conditioner. The control method includes: The maximum opening angle of the air guide plate is determined based on the user's height and the distance between the user and the air conditioner. When the air guide plate is opened at the maximum opening angle or an opening angle below the maximum opening angle, the leeward side can shield the internal components of the air conditioner to prevent the internal components of the air conditioner from being exposed through the first air inlet. The opening angle of the air guide plate is adjusted according to at least one of the environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle; wherein the opening angle is less than or equal to the maximum opening angle; wherein the opening angle of the air guide plate is the angle between the windward surface and the vertical direction.

[0006] Optionally, determining the actual opening angle of the air guide vane based on at least one of environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle, includes: When the air conditioner is in normal operating mode, the temperature difference between the ambient temperature and the set temperature is obtained; the temperature difference is an absolute value. The opening angle of the air guide plate is adjusted according to the temperature difference and the maximum opening angle.

[0007] Optionally, adjusting the opening angle of the air guide plate based on the temperature difference and the maximum opening angle includes: If the temperature difference is greater than the first temperature difference threshold, then the opening angle of the air guide plate is adjusted to the maximum opening angle; If the temperature difference is less than the second temperature difference threshold, adjust the opening angle of the air guide plate to 0. If the temperature difference is between the first temperature difference threshold and the second temperature difference threshold, the opening angle of the air guide plate is adjusted to the product of the maximum opening angle and the first preset coefficient; wherein, the first preset coefficient is β, 0 < β < 1.

[0008] Optionally, determining the actual opening angle of the air guide vane based on at least one of environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle, further includes: After the opening angle of the air guide plate is adjusted to the actual opening angle and the air conditioner operates in the normal mode for a preset time, the temperature difference between the ambient temperature and the set temperature, as well as the number of times the air guide plate has been adjusted, are obtained again. When the number of adjustments is less than the preset number, the opening angle of the air guide plate is readjusted based on the newly acquired temperature difference value and the maximum opening angle. When the preset number of adjustments is reached, if the temperature difference after the last adjustment of the air guide plate's opening angle is still within the temperature threshold range before the adjustment, a prompt message is generated to alert the user.

[0009] Optionally, adjusting the opening angle of the air guide vane based on at least one of environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle, includes: When the air conditioner is in the noise reduction mode, the noise difference between the operating noise and the ambient noise is obtained; the operating noise is greater than the ambient noise. If the noise difference is greater than the noise difference threshold, the opening angle of the air guide plate will be reduced based on the current opening angle of the air guide plate. If the noise difference is less than the noise difference threshold, the current opening angle of the air guide plate is maintained. Wherein, the current opening angle is less than or equal to the maximum opening angle.

[0010] Optionally, adjusting the opening angle of the air guide vane based on at least one of environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle, includes: When the air conditioner is in dehumidification mode, the humidity difference between the ambient humidity and the set humidity is obtained; the ambient humidity is greater than the set humidity. When the humidity difference is greater than the humidity difference threshold, the opening angle of the air guide plate is adjusted to the maximum opening angle. If the humidity difference is less than the humidity difference threshold, the opening angle of the air guide plate is adjusted to be the product of the maximum opening angle and the second preset coefficient; wherein, the second preset coefficient is γ, 0 < γ < 1.

[0011] Optionally, when the humidity difference is greater than a humidity difference threshold, the control method further includes: Control the air conditioner's fan to reverse so that airflow inside the air conditioner is blown out from the first air inlet; and / or When the humidity difference is less than a humidity difference threshold, the control method further includes: Obtain the temperature of the evaporator; If the temperature of the evaporator is lower than the preset temperature threshold, the fan of the air conditioner is reversed so that the airflow inside the air conditioner is blown out from the first air inlet; and / or the electric auxiliary heating device is started to heat the airflow. If the temperature of the evaporator is greater than a preset temperature threshold, the fan of the air conditioner is controlled to rotate in the forward direction so that airflow is introduced into the air conditioner from the first air inlet.

[0012] Secondly, this application also proposes a control device for an air conditioner, the air conditioner having a first air inlet on a visible panel and an air guide plate on the first air inlet; the air guide plate has a leeward side and a windward side; when the first air inlet is opened, the leeward side of the air guide plate is tilted downward to shield the internal components of the air conditioner. The control device includes: The determining module is used to determine the maximum opening angle of the air guide plate based on the user's height and the distance between the user and the air conditioner; when the air guide plate is opened at the maximum opening angle and an opening angle below the maximum opening angle, the leeward side can shield the internal components of the air conditioner to prevent the internal components of the air conditioner from being exposed through the first air inlet; An adjustment module is used to adjust the opening angle of the air guide plate according to at least one of environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle; wherein the opening angle is less than or equal to the maximum opening angle; wherein the opening angle of the air guide plate is the angle between the windward surface and the vertical direction.

[0013] Thirdly, this application also proposes an air conditioner, comprising: A visual panel, wherein a first air inlet is provided on the visual panel; An air guide plate is provided at the first air inlet; the air guide plate has a leeward side and a windward side; when the first air inlet is opened, the leeward side of the air guide plate is tilted downward to shield the internal components of the air conditioner. A controller configured to perform the control method as described above.

[0014] Fourthly, this application also proposes a computer-readable storage medium having a computer program stored thereon, the computer program being loaded by a processor to perform the steps in the control method for the air conditioner as described above.

[0015] In the technical solution of this application embodiment, the maximum opening angle of the air guide plate is determined based on the user's height and the distance between the user and the air conditioner. Then, the opening angle of the air guide plate is adjusted based on at least one of the environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle. This ensures that when adjusting the opening angle of the air guide plate based on at least one of the environmental parameters and the operating noise, the opening angle of the air guide plate is less than or equal to the maximum opening angle. This allows the air conditioner to meet adjustment requirements while also allowing the air guide plate to shield the internal components of the air conditioner through its leeward side, preventing the internal components from being exposed through the first air inlet. This prevents the user from observing the internal components when the air guide plate is open, improving the aesthetic appearance of the air conditioner when the air guide plate is open.

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0021] This application provides an air conditioner and its control method, apparatus, and computer-readable storage medium, which will be described in detail below.

[0022] Reference Figure 1 As shown, the air conditioner 100 includes a frame, with the front side of the frame and a visible panel 120 fixedly connected. An air outlet is also provided on the lower side of the visible panel 120, and a movable air sweeping plate is provided at the air outlet. An air inlet grille 130 is provided on the top of the frame, defining a second air inlet for the air conditioner 100. The second air inlet can be normally open; when the air conditioner 100 is operating normally, ambient air enters the air conditioner 100 through the second air inlet, passes through the evaporator, exchanges heat with the refrigerant inside the evaporator, and is then discharged into the environment through the air outlet to regulate the air parameters in the environment. These air parameters include, but are not limited to, air humidity and air temperature. It should be noted that the environmental parameters mentioned in this embodiment should be understood as the air parameters in the environment regulated by the air conditioner 100; for example, if the air conditioner 100 is installed in the living room, the environmental parameters are the air parameters in the living room, such as the air temperature and air humidity.

[0023] In the technical solution of this application embodiment, the air conditioner 100 has a first air inlet 121 disposed on a visible panel 120 and an air guide plate 110 disposed on the first air inlet 121. The first air inlet 121 is provided on the visible panel 120 as an auxiliary air inlet to the second air inlet, thereby increasing the air intake volume of the air conditioner 100. It is easily understood that the first air inlet 121 of the air conditioner 100 is located at the top; during installation, the structure will create wind resistance, reducing the air volume entering from the first air inlet 121. Since there is no obstruction in front of the visible panel 120, it is a good choice to have an air inlet. However, opening an air inlet on the panel 120 would affect the overall aesthetics of the air conditioner 100. Therefore, this embodiment retains the second air inlet and provides a first air inlet 121 on the visible panel 120. A guide vane 110 is provided on the first air inlet 121 so that when the first air inlet 121 is not in use, the guide vane 110 closes the visible panel 120, maintaining continuity with it, thus making the air conditioner 100 aesthetically pleasing and continuous. When the guide vane 110 is open, it has a leeward side 112 and a windward side 111 arranged opposite each other. When the first air inlet 121 is opened, the leeward side 112 tilts downwards to shield the internal components of the air conditioner 100, preventing the user from observing them. Thus, the aesthetics of the air conditioner 100 are maintained even when the guide vane 110 is open.

[0024] In the technical solution of the embodiment, when the air guide plate 110 is opened, the leeward side 112 is tilted downward and the windward side 111 is tilted upward, such as... Figure 2 As shown; when the air guide plate 110 is closed, as Figure 3 As shown, the leeward side 112 is on the same plane as the outer surface of the visible panel 120, or forms a continuous plane or curved surface with the outer surface of the visible panel 120; in this case, the windward side 111 faces the inside of the air conditioner 100. Further, referring to... Figure 2 As shown, when the air guide plate 110 is opened, the opening angle of the air guide plate 110 is α, which is defined as the angle between the windward surface 111 and the vertical direction.

[0025] like Figure 4 As shown, the air guide plate 110 is driven by a drive device 140. The drive device 140 includes a motor 141 and a transmission mechanism. The shaft position 113 (shaft hole or shaft) of the air guide plate 110 is rotatably connected to the frame or the viewing panel 120. The motor 141 is fixed inside the frame or the viewing panel 120 and is used to drive the transmission mechanism to open or close the air guide plate 110. The transmission mechanism includes a crank 143 and a connecting rod 142. Figure 4As shown, one end of connecting rod 142 is fixed to the shaft of motor 141, and the other end is connected to crank 143 via a rotating shaft to form a rotating pair. The other end of crank 143 is fixed to air guide plate 110. When air guide plate 110 is open, as shown, motor 141 rotates counterclockwise, driving connecting rod 142 to move outward of air conditioner 100. Crank 143 rotates, causing air guide plate 110 to rotate outward around the limiting shaft, increasing the air intake of air conditioner 100. When air guide plate 110 is closed, as shown... Figure 3 As shown, the motor 141 rotates clockwise, driving the connecting rod 142 to move inward towards the air conditioner 100. The crank 143 rotates, causing the air guide plate 110 to rotate inward around the limiting axis and close, thereby reducing the air intake of the air conditioner 100. Under a large heat exchange load, opening the air guide plate 110 effectively increases the air intake of the air conditioner, improves the heat exchange efficiency, and provides sufficient air circulation under high load conditions that require rapid cooling or heating. At the same time, driving the air guide plate 110 to rotate via the crank 143 and connecting rod 142 helps to prevent the motor 141 from being externally mounted or exposed, thus avoiding affecting the aesthetics of the air conditioner 100.

[0026] Even when the air deflector 110 is open, the user still has a certain possibility of observing the interior of the air conditioner 100. Therefore, this application determines the maximum opening angle of the air deflector 110 based on the user's height and the distance between the user and the air conditioner 100. This ensures that when the air deflector 110 is opened at or below the maximum opening angle, the leeward side 112 can shield the internal components of the air conditioner 100, preventing the internal components of the air conditioner 100 from being exposed through the first air inlet 121, thereby preventing the user from observing the internal components when the air deflector 110 is open.

[0027] like Figure 5 As shown, Figure 5 This example illustrates the principle of how an air conditioner 100, when opened to its maximum angle, obstructs the user's view, according to an embodiment of this application. Let the installation height of the air conditioner 100 be L, the user's height be l, and the distance between the user and the air conditioner 100 be S. Then, the maximum opening angle α is determined. max for: α max =180°-2*arctan(S / (Ll)) It should be noted that L is the height of the air guide plate 110 from the ground. It should also be noted that the spacing S is the distance between the user and the air conditioner 100 projected onto the perpendicular surface of the visible panel 120. Figure 5 As shown. The maximum opening angle is negatively correlated with user height, that is, with the same spacing, the taller the user, the smaller the maximum opening angle; the maximum opening angle is also negatively correlated with spacing, that is, with the same user height, the larger the spacing, the smaller the maximum opening angle.

[0028] It should be noted that user height refers to the user's dimensions in the vertical direction. Users can be seated, lying down, or standing. User height and spacing can be measured using sensors on the air conditioner 100, such as infrared sensors.

[0029] like Figure 6 The diagram shown is a flowchart illustrating an embodiment of the control method for an air conditioner in this application. null Control method of tuner include: The control method includes: S100, determine the maximum opening angle of the air guide plate according to the user's height and the distance between the user and the air conditioner; when the air guide plate is opened at the maximum opening angle and an opening angle below the maximum opening angle, the leeward side can shield the internal components of the air conditioner to prevent the internal components of the air conditioner from being exposed through the first air inlet; S200, adjust the opening angle of the air guide plate according to at least one of the environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle; wherein the opening angle is less than or equal to the maximum opening angle; wherein the opening angle of the air guide plate is the angle between the windward surface and the vertical direction.

[0030] In the technical solution of this application embodiment, the maximum opening angle of the air guide plate is determined based on the user's height and the distance between the user and the air conditioner. Then, the opening angle of the air guide plate is adjusted based on at least one of the environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle. This ensures that when adjusting the opening angle of the air guide plate based on at least one of the environmental parameters and the operating noise, the opening angle of the air guide plate is less than or equal to the maximum opening angle. This allows the air conditioner to meet adjustment requirements while also allowing the air guide plate to shield the internal components of the air conditioner through its leeward side, preventing the internal components from being exposed through the first air inlet. This prevents the user from observing the internal components when the air guide plate is open, improving the aesthetic appearance of the air conditioner when the air guide plate is open.

[0031] In some embodiments, when there are multiple users in the space where the air conditioner is located, determining the maximum opening angle of the air guide plate based on the user's height and the distance between the user and the air conditioner includes: The maximum nominal opening angle of the multiple air guide vanes is determined based on the height of each user and the distance between each user and the air conditioner. The minimum value among the maximum nominal opening angles is taken as the maximum opening angle of the air guide.

[0032] For example, if there are 3 people in the space where the air conditioner is located, and the maximum nominal opening angles are determined to be 45°, 55° and 48° respectively, then 45° is taken as the maximum opening angle.

[0033] As an optional implementation of the above embodiments, such as Figure 7 As shown, determining the actual opening angle of the air guide vane based on at least one of the environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle, includes: S211, when the air conditioner is in normal operating mode, the temperature difference between the ambient temperature and the set temperature is obtained; the temperature difference is an absolute value. S212, adjust the opening angle of the air guide plate according to the temperature difference and the maximum opening angle.

[0034] It should be noted that the normal mode is when the air conditioner performs only its basic functions. The basic function of the air conditioner is to adjust the temperature of the environment it is regulating, such as heating and cooling modes. When the air conditioner is in normal mode, the opening angle of the air guide vane is adjusted based on the temperature difference between the ambient temperature and the set temperature, as well as the maximum opening angle. This ensures that, while maintaining temperature regulation, the air guide vane, on its leeward side, shields the internal components of the air conditioner, preventing them from being exposed through the first air inlet. This avoids the user being able to observe the internal components when the air guide vane is open, thus improving the aesthetic appearance of the air conditioner when the air guide vane is open.

[0035] For example, if an air conditioner is operating in heating mode, the indoor temperature is 5℃, the set temperature is 25℃, and the maximum opening angle is 50°, then the difference between the indoor temperature and the set temperature is 20℃. The air deflector can then open at a 50° angle.

[0036] For example, if an air conditioner is running in cooling mode, the indoor temperature is 28°C, the set temperature is 26°C, and the maximum opening angle is 40°, then the difference between the indoor temperature and the set temperature is 2°C. The air deflector can then open at a 10° angle.

[0037] As an optional implementation of the above embodiments, adjusting the opening angle of the air guide plate according to the temperature difference and the maximum opening angle includes: If the temperature difference is greater than the first temperature difference threshold, then the opening angle of the air guide plate is adjusted to the maximum opening angle; If the temperature difference is less than the second temperature difference threshold, adjust the opening angle of the air guide plate to 0. If the temperature difference is between the first temperature difference threshold and the second temperature difference threshold, the opening angle of the air guide plate is adjusted to the product of the maximum opening angle and the first preset coefficient; wherein, the first preset coefficient is β, 0 < β < 1.

[0038] In some embodiments of this application, a first temperature difference threshold and a second temperature difference threshold are provided inside the air conditioner. The opening angle of the air guide vane is determined based on the relationship between the temperature difference value and the first and second temperature difference thresholds. This allows for a more precise match between the opening angle of the air guide vane and the actual opening angle of the air conditioner. Furthermore, while ensuring precise temperature adjustment, the air guide vane, through its leeward side, shields the internal components of the air conditioner, preventing them from being exposed through the first air inlet. This avoids the user being able to observe the internal components when the air guide vane is open, thus improving the aesthetic appearance of the air conditioner when the air guide vane is open.

[0039] In some embodiments, when the first temperature difference is greater than or equal to the first temperature difference threshold, the opening angle of the air guide plate is adjusted to the maximum opening angle, so that the air volume entering the air conditioner reaches the maximum without exposing the internal components, and the temperature can be adjusted quickly.

[0040] In some embodiments, when the temperature difference is less than or equal to the second temperature threshold, the indoor temperature is close to the set temperature, and the opening angle of the air guide plate is adjusted to 0. At this time, the air conditioner can take in air through the second air inlet to adjust the indoor temperature.

[0041] In some embodiments, when the temperature difference is between a first temperature threshold and a second temperature threshold, the opening angle of the air guide plate is between 0 and the maximum opening angle to regulate the indoor temperature. In an embodiment, the first preset coefficient is β, for example, β can be set to 1 / 3, 1 / 2, or 2 / 3, etc. In other embodiments, in order to regulate the temperature more precisely, the first preset coefficient is set according to the temperature difference, and the temperature difference is positively correlated with the first preset coefficient, that is, the larger the temperature difference, the larger the first preset coefficient.

[0042] In some embodiments, when the temperature difference is equal to the second temperature threshold, the air deflector can also be opened, for example, by opening to 10% of the maximum opening angle, so that the temperature can be quickly adjusted to close to the set temperature.

[0043] In some embodiments, the first temperature threshold can be set to 5°C and the second temperature threshold can be set to 1°C. For example, the first temperature threshold can be set to 10°C and the second temperature threshold can be set to 2°C.

[0044] In this embodiment, the first air inlet is an auxiliary air inlet for the air conditioner, normally closed via a deflector. The first air inlet is only opened when the temperature difference required by the air conditioner is large, thereby increasing the airflow. Therefore, in some embodiments of this application, after the deflector is opened, the indoor temperature needs to be monitored in real time to determine whether the opening of the deflector is effective or whether further adjustment of the deflector's opening angle is necessary.

[0045] As an optional implementation of the above embodiments, determining the actual opening angle of the air guide vane based on at least one of the environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle, further includes: After the opening angle of the air guide plate is adjusted to the actual opening angle and the air conditioner operates in the normal mode for a preset time, the temperature difference between the ambient temperature and the set temperature, as well as the number of times the air guide plate has been adjusted, are obtained again. When the number of adjustments is less than the preset number, the opening angle of the air guide plate is readjusted based on the newly acquired temperature difference value and the maximum opening angle. When the preset number of adjustments is reached, if the temperature difference after the last adjustment of the air guide plate's opening angle is still within the temperature threshold range before the adjustment, a prompt message is generated to alert the user.

[0046] In this embodiment, after the air guide plate's opening angle is adjusted to the actual opening angle and the air conditioner operates in the normal mode for a preset time, the temperature difference between the ambient temperature and the set temperature, as well as the number of times the air guide plate has been adjusted, are re-acquired to determine whether the opening is effective or whether further adjustment of the air guide plate's opening angle is needed after opening. If the number of adjustments is less than a preset number, the opening angle of the air guide plate is readjusted based on the re-acquired temperature difference and the maximum opening angle; that is, by setting the number of adjustments, the air conditioner can be configured to make multiple adjustments to further readjust the opening angle of the air guide plate based on the re-acquired temperature difference and the maximum opening angle; when the number of adjustments reaches the preset number, if the temperature difference after the last adjustment of the air guide plate's opening angle is still within the temperature threshold range before the adjustment, then the adjustment of the air guide plate is invalid or more adjustments are needed to reach the required temperature, and a prompt message is generated to remind the user.

[0047] Reference Figure 8As shown, when the air conditioner is running in normal mode, if the temperature difference exceeds the first temperature difference threshold, the first adjustment attempt will have 0 adjustments, not reaching the preset number of adjustments. At this point, the air guide vane will open to its maximum angle, and the adjustment count will increment by 1. After a preset duration, the temperature difference will be re-evaluated to see if it exceeds the first temperature threshold. If it does, since the adjustment count is 1 and the preset number of adjustments has not been reached, the air guide vane will open to its maximum angle, reaching the second adjustment. The preset duration will continue, and the temperature difference will be re-evaluated again. If the adjustment count is 2 and the preset number of adjustments has not been reached, the air guide vane will open to its maximum angle, reaching the third adjustment. The preset duration will continue, and the temperature difference will be re-evaluated again. If the adjustment count is 3 and the preset number of adjustments has been reached, a prompt message will be generated to inform the user that the temperature is difficult to adjust after the air guide vane is running at its maximum angle. The user can then check the air conditioner based on the prompt message or be advised to adjust its position or height to increase the maximum opening angle, thus increasing the upper limit of the air guide vane's opening angle.

[0048] In this embodiment, if the temperature difference drops below the first temperature difference threshold after the air guide plate has been opened to its maximum angle, it indicates that opening the air guide plate helps regulate the temperature. The next judgment cycle then begins. If the temperature difference is between the first and second temperature difference thresholds, the first adjustment cycle has 0 adjustments, not reaching the preset number. The air guide plate is then adjusted by multiplying the maximum opening angle by the first preset coefficient, increasing the adjustment cycle by 1. After a preset running time, the temperature difference is re-evaluated to see if it exceeds the second temperature threshold. If it does, since the adjustment cycle is 1 and the preset number has not been reached, the air guide plate is adjusted by multiplying the maximum opening angle by the first preset coefficient, increasing the adjustment cycle to 2. The cycle continues for the preset time, and the temperature difference is re-evaluated to see if it exceeds the second temperature threshold. If it does, since the adjustment cycle is 2 and the preset number has not been reached, the air guide plate is then adjusted by multiplying the maximum opening angle by the first preset coefficient, increasing the adjustment cycle to 2. The cycle continues for the preset time, and the temperature difference is re-evaluated to see if it exceeds the second temperature threshold. If it does, since the adjustment cycle is 2 and the preset number has not been reached, the air guide plate is then adjusted to see the second temperature threshold. The air deflector is adjusted three times at the maximum opening angle multiplied by a first preset coefficient. The process continues for a preset duration, then the temperature difference is reassessed to determine if it exceeds a second temperature threshold. If so, since the preset number of adjustments is three, a prompt message is generated to alert the user that the temperature is difficult to adjust after the air deflector has been operated at its maximum opening angle multiplied by the first preset number of times. The user can then check the air conditioner based on the prompt message or be advised to adjust its position or height to increase the maximum opening angle, thereby increasing the upper limit of the air deflector's opening angle and ultimately its actual opening angle.

[0049] In an embodiment, if the temperature difference drops below the second temperature difference threshold after the air guide plate is opened at its maximum opening angle multiplied by a first preset coefficient, it indicates that opening the air guide plate helps with temperature regulation, and the air guide plate is then closed.

[0050] In this embodiment, if the temperature difference is between a first temperature threshold and a second temperature threshold after the air conditioner is turned on, a judgment loop is entered: If the temperature difference is between the first and second temperature thresholds, the first adjustment has 0 adjustments, not reaching the preset number. At this time, the air guide plate is adjusted by multiplying the maximum opening angle by a first preset coefficient, and the adjustment count is incremented by 1. After running for a preset time, the temperature difference is re-judged to see if it is greater than the second temperature threshold. If it is, since the adjustment count is 1, not reaching the preset number, the air guide plate is adjusted by multiplying the maximum opening angle by the first preset coefficient, reaching the second adjustment count. The preset time continues, and the temperature difference is re-judged to see if it is greater than the second temperature threshold. If so, since the adjustment count is 2, which is less than the preset count, the air guide plate will adjust the opening angle by multiplying the maximum opening angle by the first preset coefficient. After 3 adjustments, the system will continue to run for the preset duration and re-evaluate whether the temperature difference is greater than the second temperature threshold. If so, since the adjustment count is 3, which is the preset count, a prompt message will be generated to remind the user that the temperature is difficult to adjust after the air guide plate has run at the opening angle multiplied by the first preset count. At this time, the user can check the air conditioner according to the prompt message or adjust the position or height to increase the maximum opening angle, which can increase the upper limit of the opening angle of the air guide plate, and thus increase the upper limit of the actual opening angle of the air guide plate.

[0051] In this embodiment, if the temperature difference is below the second temperature threshold when the air conditioner is turned on, then it is not necessary to open the air deflector.

[0052] In the above embodiments, the preset duration and preset number of times can be set by the system. In some embodiments, the preset duration and preset number of times can be fixed parameters. In some embodiments, the preset duration and preset number of times can be adjustable parameters; for example: Based on the temperature difference, at least one of the preset duration and preset number of times is determined. For example, when the temperature difference is greater than a first preset threshold, at least one of the preset duration and preset number of times is determined based on the ratio of the temperature difference to the first preset threshold. The larger the ratio, the longer the preset duration and preset number of times are determined; a larger temperature difference indicates a greater load on the air conditioner, and therefore the longer the air guide needs to be open when the temperature difference drops below the first temperature difference threshold.

[0053] As an optional implementation of the above embodiments, adjusting the opening angle of the air guide vane based on at least one of environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle, includes: When the air conditioner is in sleep mode, the noise difference between the operating noise and the ambient noise is obtained; the operating noise is greater than the ambient noise. If the noise difference is greater than the noise difference threshold, the opening angle of the air guide plate will be reduced based on the current opening angle of the air guide plate. If the noise difference is less than the noise difference threshold, the current opening angle of the air guide plate is maintained. Wherein, the current opening angle is less than or equal to the maximum opening angle.

[0054] In this embodiment, the sleep mode is a noise control measure implemented when the air conditioner is operating in normal mode, aiming to achieve low noise levels during heating or cooling. Combined with... Figure 9 As shown, after the air conditioner is turned on, the maximum opening angle is determined. It is then determined whether the air conditioner is set to sleep mode; if so, the opening angle of the air guide vane is adjusted based on the noise difference between the operating noise and the ambient noise, and a noise difference threshold. If the noise difference is greater than the noise difference threshold, the opening angle of the air guide vane is reduced from its current opening angle; if the noise difference is less than the noise difference threshold, the current opening angle of the air guide vane is maintained. In some embodiments, when the noise difference is equal to the noise difference threshold, the opening angle of the air guide vane is reduced from its current opening angle.

[0055] In some embodiments, when the air conditioner is running in sleep mode, whether heating or cooling, the air deflector can be opened at the current opening angle. That is, the opening angle of the air deflector, i.e., the current opening angle, can be determined first by the temperature difference. Then, it is determined whether the noise level meets the set noise requirement; if it does, the air deflector continues to operate at the current opening angle; if not, the opening angle of the air deflector is reduced from the current opening angle to reduce noise.

[0056] During the noise reduction process, the noise level is checked every preset time interval to determine if the noise level meets the requirements. If it does, the opening angle of the last adjustment is maintained. If it does not meet the requirements, the opening angle is reduced until the air guide is closed or the noise reduction requirements are met.

[0057] It should be noted that, in this embodiment, the operating noise of the air conditioner is greater than the ambient noise.

[0058] As an optional implementation of the above embodiments, adjusting the opening angle of the air guide vane based on at least one of environmental parameters and the operating noise of the air conditioner, as well as the maximum opening angle, includes: When the air conditioner is in dehumidification mode, the humidity difference between the ambient humidity and the set humidity is obtained; the ambient humidity is greater than the set humidity. When the humidity difference is greater than the humidity difference threshold, the opening angle of the air guide plate is adjusted to the maximum opening angle. If the humidity difference is less than the humidity difference threshold, the opening angle of the air guide plate is adjusted to be the product of the maximum opening angle and the second preset coefficient; wherein, the second preset coefficient is γ, 0 < γ < 1.

[0059] In this embodiment, the air conditioner also features a dehumidification mode. Combined with... Figure 10 As shown, when the difference between the ambient humidity and the set humidity is large, the opening angle of the air guide plate is adjusted to the maximum opening angle to quickly reduce the air humidity. When the humidity difference is small, the opening angle of the air guide plate is adjusted to below the maximum opening angle. When the humidity difference is small, the opening angle of the air guide plate is between 0 and the maximum opening angle to dehumidify the room. In this embodiment, the second preset coefficient is γ, for example, γ can be set to 1 / 3, 1 / 2, or 2 / 3, etc. In other embodiments, for more precise dehumidification, the second preset coefficient is set according to the temperature difference, and the temperature difference is positively correlated with the second preset coefficient, that is, the larger the temperature difference, the larger the second preset coefficient.

[0060] In some embodiments, when the humidity difference reaches the set requirement, the dehumidification mode and the air deflector can be turned off.

[0061] As an optional implementation of the above embodiments, when the humidity difference is greater than a humidity difference threshold, the control method further includes: Control the air conditioner's fan to reverse so that airflow inside the air conditioner is blown out from the first air inlet; and / or When the humidity difference is less than a humidity difference threshold, the control method further includes: Obtain the temperature of the evaporator; If the temperature of the evaporator is lower than the preset temperature threshold, the fan of the air conditioner is reversed so that the airflow inside the air conditioner is blown out from the first air inlet; and / or the electric auxiliary heating device is started to heat the airflow. If the temperature of the evaporator is greater than a preset temperature threshold, the fan of the air conditioner is controlled to rotate in the forward direction so that airflow is introduced into the air conditioner from the first air inlet.

[0062] In the embodiments, combined with Figure 10 As shown, when the air conditioner starts dehumidifying, when the humidity difference is... When H is greater than 20%, the air guide plate is adjusted to its maximum opening angle, the motor reverses, and the first air inlet is used for air outlet. This increases air resistance, reduces air velocity, and prolongs the residence time of the airflow between the evaporator fins, thus enhancing the dehumidification effect. When humidity (H) is less than 20%, the built-in temperature sensor automatically detects the evaporator temperature. If the temperature is below 0℃, the electric auxiliary heating is automatically activated to prevent excessive drop in room temperature caused by dehumidification. The air guide vane can also be lowered to 50% of its maximum opening angle, and the motor reverses direction. Conversely, if the evaporator temperature is above 0℃, during dehumidification, the condensate on its surface is very low, and the dust in the air is not easily blown away (relative to dry air). Furthermore, the airflow is reduced during dehumidification, and dust may not be blown onto the filter. Therefore, the motor rotates forward for 10 seconds to blow out any dust accumulated during the dehumidification process, and then the operation is shut off.

[0063] During dehumidification: When the air deflector is open, air flows out from both the air intake grille and the second air intake simultaneously, gradually increasing the airflow. As the air deflector opening widens, the airflow from the outlets increases, and the dehumidification capacity of the air conditioner also increases. The dehumidification capacity can be expressed as D = ρ * Q * (din - dout), where ρ is the air density, Q represents the air intake volume, and din and dout represent the moisture content of the intake and outlet air, respectively.
