Technical Field

[0001] This invention relates to the field of air conditioner control technology, and in particular to an air volume control method, device, storage medium, and air conditioner. Background Technology

[0002] Air conditioners are becoming increasingly common in households. As people's living standards continue to improve, the demand for air conditioners is no longer limited to simple cooling and heating functions. How to provide users with a comfortable environment has become a topic of greater concern and a hot research area for air conditioner manufacturers.

[0003] To improve room temperature uniformity and airflow variety, most air conditioners have vertical swing functionality. However, the vertical swing function of conventional air conditioners has significant drawbacks. As the swing angle changes, the airflow decreases significantly, and the noise level also varies considerably, resulting in a poor user experience. Furthermore, the relatively small vertical swing angle of current air conditioners creates large blind spots during cooling or heating, leading to uneven room temperature.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0008] The air outlet area difference is determined based on the current air outlet area and the preset air outlet area;

[0009] The air volume difference is determined based on the difference in air outlet area; and

[0010] The fan speed of the air conditioner is adjusted according to the air volume difference.

[0011] Optionally, obtaining the current air outlet area of ​​the air conditioner includes:

[0012] Real-time acquisition of the current air delivery angle during the movement of the air guide vane of the air conditioner; and

[0013] The current air outlet area is determined based on the current air supply angle.

[0014] Optionally, before determining the air outlet area difference based on the current air outlet area and the preset air outlet area, the method further includes:

[0018] Optionally, determining the preset air outlet area based on the preset air supply angle includes:

[0019] Obtain the initial extension length corresponding to the air guide plate; and

[0020] The preset air outlet area is determined based on the initial extension length and the preset air supply angle.

[0021] Optionally, obtaining the initial extension length corresponding to the air guide plate includes:

[0022] Obtain the current indoor ambient temperature and the user-input set temperature when the air conditioner starts; and

[0023] The initial extension length of the air guide plate is determined based on the current indoor ambient temperature and the set temperature.

[0024] Optionally, before adjusting the fan speed of the air conditioner based on the air volume difference, the method further includes:

[0025] The airflow difference is compared with a preset difference threshold; and

[0026] When the air volume difference is greater than or equal to the preset difference threshold, the step of adjusting the fan speed of the air conditioner according to the air volume difference is executed.

[0027] Optionally, after comparing the airflow difference with a preset difference threshold, the method further includes:

[0028] Obtain the current operating parameters of the air conditioner; and

[0029] When the air volume difference is less than the preset difference threshold, the air conditioner is controlled to continue operating according to the current operating parameters.

[0030] Furthermore, to achieve the above objectives, the present invention also proposes an airflow control device, the airflow control device comprising:

[0031] The acquisition module is used to acquire the current air outlet area of ​​the air conditioner when the air conditioner is in the swing mode;

[0032] The calculation module is used to determine the air outlet area difference based on the current air outlet area and the preset air outlet area;

[0033] The query module is used to determine the air volume difference based on the air outlet area difference;

[0034] An adjustment module is used to adjust the fan speed of the air conditioner according to the air volume difference.

By determining the air volume difference through the air outlet area difference during the air conditioner's swing process and adjusting the fan speed based on the air volume, the air volume of the air conditioner during the swing process is kept constant. The constant air volume makes the noise of the air conditioner stable during the up and down swing, thus improving the user experience. Attached Figure Description

[0048] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0050] Reference Figure 1 , Figure 1 This is a schematic diagram of the air conditioner structure in the hardware operating environment involved in the embodiments of the present invention.

[0051] like Figure 1 As shown, the air conditioner may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen and an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0052] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the air conditioner and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0053] like Figure 1As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and an airflow control program.

[0054] exist Figure 1 In the air conditioner shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the air conditioner of the present invention can be set in the air conditioner. The air conditioner calls the air volume control program stored in the memory 1005 through the processor 1001 and executes the air volume control method provided in the embodiment of the present invention.

[0055] This invention provides an airflow control method, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of an airflow control method according to the present invention.

[0056] In this embodiment, the air volume control method includes the following steps:

[0057] Step S10: When the air conditioner is in swing mode, obtain the current air outlet area of ​​the air conditioner.

[0058] It should be noted that the executing entity in this embodiment can be an air volume control device, which can be an electronic device such as a personal computer or server, or other controllers and devices that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment and the following embodiments, the air volume control device is used as an example to illustrate the air volume control method of the present invention.

[0059] In this embodiment, in the prior art, during the swing mode, the change in the angle of the air guide plate causes a change in the air outlet area of ​​the air conditioner. The air outlet area determines the air volume of the air conditioner; the larger the air outlet area, the greater the corresponding air volume. Therefore, the constantly changing air outlet area causes changes in the air volume of the air conditioner, resulting in different air volumes at each moment during the swing process. Especially when the air outlet area is small, the air volume is severely reduced. Furthermore, in the prior art, to prevent the air from blowing directly on people, the swing is limited to the upper half of the stroke in cooling mode and to the lower half of the stroke in heating mode, creating a large swing blind zone in the room and resulting in a large temperature difference in the room. In this embodiment, to solve the above problems, the structure of the air conditioner is improved, such as... Figure 3 As shown. Among them, the impeller 1 is used to control the speed of the air conditioner fan, the telescopic device 2 is used to push out or cover the air outlet 5 of the dual-flow air guide plate 4, and the sliding device 3 realizes the up and down movement of the dual-flow air guide plate. The telescopic device 2 can change the distance between the dual-flow air guide plate 4 and the air conditioner, and the sliding device 3 can change the air outlet angle of the dual-flow air guide plate 4. The two work together to change the air outlet area of ​​the air conditioner.

[0060] It should be noted that this embodiment can adjust the air conditioner's operating mode according to user-input control commands. For example, based on a user-inputted swing command, the air conditioner's operating mode can be adjusted to swing mode. Furthermore, this embodiment can also set a preset time, and when the preset time is reached, the air conditioner's operating mode can be automatically adjusted to swing mode. This embodiment can also adjust the air conditioner's operating mode in other ways, and can be set accordingly according to actual conditions. This embodiment does not impose any limitations on this.

[0061] In specific implementation, the current air outlet area is the air outlet area corresponding to the air conditioner during swing operation. In this embodiment, the air outlet area corresponding to the air conditioner during swing operation can also be obtained based on the constant air volume command input by the user. Furthermore, in this embodiment, a preset time can also be set, and the air outlet area corresponding to the air conditioner during swing operation can be automatically obtained when the preset time is reached. In this embodiment, the air outlet area corresponding to the air conditioner during swing operation can also be obtained in other ways, and can be set accordingly according to the actual situation. This embodiment does not limit this.

[0062] Furthermore, the air outlet area of ​​the air conditioner is related to the air delivery angle of the dual-flow guide vane. Therefore, step S10 can be implemented as follows: after the air conditioner starts the swing mode, the air delivery angle of the dual-flow guide vane during the swing process is obtained, i.e., the current air delivery angle. Then, the air outlet area corresponding to the air conditioner during the swing operation can be calculated based on this air delivery angle. It should be emphasized that during the swing process, the upper and lower ends of the dual-flow guide vane and the air conditioner form a matrix-like shape. The air outlet area between the upper end of the dual-flow guide vane and the air conditioner, and the air outlet area between the lower end of the dual-flow guide vane and the air conditioner can be approximated by calculating the area of ​​a matrix. Of course, other methods can also be used to calculate the air outlet area corresponding to the air outlet angle in this embodiment. It can be set according to the actual situation. This embodiment does not limit this. To ensure the feasibility of the control method, this embodiment records and stores the air outlet area corresponding to each air delivery angle in advance for subsequent calculation and retrieval.

[0063] Step S20: Determine the air outlet area difference based on the current air outlet area and the preset air outlet area.

[0064] In this embodiment, after obtaining the air outlet area (current air outlet area) corresponding to the air conditioner during swing mode, the difference between the current air outlet area and the preset air outlet area is calculated to obtain the air outlet area difference. For example, if the current air outlet area is S1 and the preset air outlet area is S2, the air outlet area difference is S1-S2. The preset air outlet area is the air outlet area when the air conditioner is in swing mode. It can be calculated based on the corresponding air outlet angle when the air conditioner is in swing mode. Alternatively, the preset air outlet area can be calculated based on a preset air outlet angle set by the user when the air conditioner is in swing mode. Of course, the preset air outlet area can be calculated using the method described in step S10 above, or other methods can be used. This embodiment does not limit this method.

[0065] Step S30: Determine the air volume difference based on the air outlet area difference.

[0066] In practice, after determining the difference in air outlet area, the difference in air volume (air volume difference) between the air conditioner when it starts swinging and during the swinging process at various times can be determined based on the determined difference in air outlet area.

[0067] It is important to emphasize that the air volume is related not only to the air outlet area but also to the fan speed. However, since the fan speed has not been adjusted in this case, it can be considered a fixed value. Therefore, the corresponding air volume difference can be directly obtained based on the correspondence between the air outlet area and the air volume difference. For example, if the air outlet area is S1, the corresponding air volume is B1; if the air outlet area is S2, the corresponding air volume is B2. Therefore, the air volume difference corresponding to the difference in air outlet areas S1-S2 is B1-B2. Furthermore, in this embodiment, other methods can be used to obtain the corresponding air volume difference based on the difference in air outlet areas. These methods can be set according to actual conditions, and this embodiment does not impose any restrictions on them.

[0068] Step S40: Adjust the fan speed of the air conditioner according to the air volume difference.

[0069] It should be noted that in this embodiment, the fan speed can be adjusted accordingly based on the air volume and speed curve, as shown in the figure below. Figure 4 As shown, Figure 4 L A This is a curve showing the relationship between air volume and rotational speed. For example, when the air velocity is 724 r / min, the corresponding air volume is 308 m³ / min. 3 / h, when the wind speed is 1096 r / min, the corresponding air volume is 655 m³ / h. 3 / h, based on the above data, the air volume difference is 347m³. 3 At / h, the corresponding wind speed adjustment is 372r / min, therefore, when the air volume difference is 347m3 At / h, the fan speed is increased by 372r / min, with an air volume difference of -347m 3 When the air volume difference is / h, the fan speed is reduced by 372 r / min. It is easy to understand that in this embodiment, the fan speed corresponding to the air volume difference can also be determined according to other methods, and can be selected according to the actual situation. This embodiment does not limit this.

[0070] Furthermore, this embodiment also ensures that the noise level of the air conditioner remains stable, for example... Figure 4 As shown, Figure 4 L B This is a curve showing the relationship between airflow and noise. When the airflow is constant, the noise level can also remain relatively stable. For example, when the airflow is 308 m³ / h... 3 At a speed of / h, the corresponding noise level remained at 26.6dB, which is consistent with the noise level when the air volume is 778m³ / h. 3 At / h, the corresponding noise level remains at 43.6dB.

[0071] This embodiment obtains the current air outlet area of ​​the air conditioner when it is in swing mode; determines the air outlet area difference based on the current air outlet area and the preset air outlet area; determines the air volume difference based on the air outlet area difference; and adjusts the fan speed of the air conditioner based on the air volume difference. By determining the air volume difference through the air outlet area difference during the air conditioner's swing process and adjusting the fan speed of the air conditioner according to the air volume, the air volume of the air conditioner during the swing process is kept constant. The constant air volume makes the noise of the air conditioner stable during the up and down swing, thus improving the user experience.

[0072] refer to Figure 5 , Figure 5 This is a flowchart illustrating a second embodiment of an airflow control method according to the present invention.

[0073] Based on the first embodiment described above, the air volume control method of this embodiment further includes, before step S20:

[0074] Step S020: Receive adjustment instructions input by the user.

[0075] It should be noted that in this embodiment, when the air conditioner is in swing mode, it can automatically adjust the dual-flow guide vane to the initial swing angle via a sliding device. The initial swing angle is preset in the air conditioner's program by the manufacturer. Furthermore, in addition to automatically adjusting the angle of the dual-flow guide vane, the air conditioner can also receive adjustment commands input by the user and adjust the dual-flow guide vane to the user-set swing angle according to the command. In this embodiment, the user can input adjustment commands to the air conditioner via a mobile terminal, a remote control paired with the air conditioner, or physical buttons on the air conditioner. The appropriate command input method can be selected according to the actual situation; this embodiment does not impose any restrictions on this.

[0076] Step S120: Extract the preset air delivery angle of the air guide plate of the air conditioner from the adjustment command.

[0077] In practice, after receiving the adjustment command, in order to accurately identify the air outlet angle set by the user, the preset air supply angle of the air guide plate can be extracted from the adjustment command based on the identifier corresponding to the air outlet angle. In this embodiment, the preset air supply angle is the air supply angle set by the user when the air conditioner is in swing mode.

[0078] Step S220: Determine the preset air outlet area based on the preset air supply angle.

[0079] It should be noted that the preset air supply angle corresponds to the air outlet area when the air conditioner is in swing mode, i.e., the preset air outlet area. Similarly, in this embodiment, the method in step S10 above can be used, or other methods can be used to calculate the preset air outlet area. This embodiment does not limit this.

[0080] Furthermore, in this embodiment, to improve the accuracy of the preset air outlet area calculation, the specific calculation process of the preset air outlet area can be implemented as follows: The aforementioned telescopic device is used to push out or cover the air outlet of the dual-flow guide plate, and the sliding device enables the up-and-down movement of the dual-flow guide plate. The telescopic device can change the distance between the dual-flow guide plate and the air conditioner, and the sliding device can change the air outlet angle of the dual-flow guide plate. Based on the distance between the dual-flow guide plate and the air conditioner and the air outlet angle, the air outlet area can be calculated. In this embodiment, to increase the air volume of the air conditioner and improve the cooling or heating effect, when the air conditioner is in swing mode, the telescopic device will first extend the dual-flow guide plate a certain distance, such as... Figure 6 As shown, L1 represents the extension length of the upper end of the dual-flow air guide plate, and L2 represents the extension length of the lower end of the dual-flow air guide plate. This distance is the initial extension length, which can be preset by the user; this embodiment does not impose any restrictions on this. After determining the initial extension length, the preset air outlet area can be calculated by combining the preset air supply angle and the rectangle calculation formula.

[0081] Furthermore, the extension distance of the dual-flow air guide plate relative to the telescopic device or air outlet, or the sum of L1 and L2, is related to the air outlet area of ​​the air conditioner. The larger the extension distance, or the larger the sum of L1 and L2, the larger the corresponding air outlet area of ​​the air conditioner, and the greater the corresponding air volume, resulting in better heating or cooling effects. In this embodiment, to further improve the heating or cooling effect of the air conditioner in swing mode, the initial extension length can be set by the user or determined based on the temperature.

[0082] In practical implementation, the indoor ambient temperature when the air conditioner is in swing mode can be obtained through a temperature sensor, which is the current indoor ambient temperature. At the same time, the user-inputted set temperature can be read through the user's input command. The initial extension length is determined based on the current indoor ambient temperature when the air conditioner is in swing mode and the user-inputted set temperature. For example, if the current indoor ambient temperature is T1 and the user-inputted set temperature is T2, the temperature difference can be determined to be T1-T2. Assuming that the extension length corresponding to T1-T2 is L, the initial extension length can be determined to be L.

[0083] In this embodiment, the initial extension length corresponding to the air guide plate is obtained; the initial air outlet area is determined according to the initial extension length and the initial air supply angle. At the same time, in order to ensure the heating or cooling effect of the air conditioner in the swing mode, the initial extension length is determined according to the indoor ambient temperature when the air conditioner is turned on in the swing mode and the set temperature input by the user.

[0084] refer to Figure 7 , Figure 7 This is a flowchart illustrating a third embodiment of an airflow control method according to the present invention.

[0085] Based on the first or second embodiment described above, a third embodiment of the air volume control method of the present invention is proposed.

[0086] Taking the first embodiment described above as an example, before step S40 in this embodiment, the following steps are included:

[0087] Step S040: Compare the air volume difference with a preset difference threshold.

[0088] It's easy to understand that constant air volume means the airflow is at a constant value. However, in practice, if the airflow is always fixed at a constant value, the fan speed will need to be adjusted frequently, reducing the fan's lifespan. In reality, it's common to compare the airflow at different times during the air conditioner's swing cycle. If the difference between the two airflows is small, then the airflow at those two times can be considered constant. For example, comparing the airflow B1 at time T1 and the airflow B2 at time T2 during the air conditioner's swing cycle, if the difference between B1 and B2 is large, i.e., the airflow difference is large, then B1 and B2 are not considered constant, and the air conditioner's fan speed needs to be adjusted. On the other hand, if the difference between B1 and B2 is small, i.e., the airflow difference is small, then B1 and B2 are considered constant. In this case, although the airflow B1 and B2 are not equal, the air conditioner's fan speed does not need to be adjusted.

[0089] In this specific implementation, the difference in air volume between different times during the air conditioner's sweeping process is determined based on a preset difference threshold. The preset difference threshold can be set according to the actual situation, and this implementation does not impose any restrictions on it.

[0090] Step S140: When the air volume difference is greater than or equal to the preset difference threshold, the fan speed of the air conditioner is adjusted according to the air volume difference.

[0091] It is easy to understand that if the difference in air volume between different moments during the air conditioner's swing process is greater than or equal to the preset difference threshold, it means that the air volume difference between these two moments is large and does not belong to constant air volume. Therefore, the fan speed of the air conditioner can be adjusted accordingly in the manner described above.

[0092] In specific implementation, the fan speed is adjusted within a preset range. The preset range can include the current fan speed ± a preset speed, and the preset speed can be values ​​such as 10 r / min, 50 r / min, 100 r / min, 200 r / min, etc. After step S140 or during step S140, the control method further includes: controlling the extension distance of the dual-flow guide vane through the telescopic device according to the airflow difference. Thus, when simply adjusting the fan speed is insufficient to keep the airflow difference within a small range (less than or equal to a preset difference threshold), adjusting the extension distance of the dual-flow guide vane can ensure that the airflow difference is less than or equal to the preset difference threshold when the air conditioner is in swing mode, thereby improving the uniformity of the swing.

[0093] Furthermore, if the difference in air volume between different moments during the air conditioner's swing mode is less than the preset difference threshold, it indicates that the air volume difference between these two moments is small and is considered constant air volume. Therefore, there is no need to adjust the air conditioner's fan speed. In this case, the air conditioner's fan operation is controlled according to the operating parameters when the air conditioner is in swing mode, i.e., the current operating parameters.

[0094] This embodiment determines the difference in air volume between different moments during the air sweeping process of the air conditioner by setting a preset difference threshold, thereby reducing the frequency of fan speed adjustment and improving the lifespan of the air conditioner fan.

[0095] Furthermore, this embodiment of the invention also proposes a storage medium storing an airflow control method program, which, when executed by a processor, implements the steps of the airflow control method described above.

[0096] Reference Figure 8 , Figure 8 This is a structural block diagram of the first embodiment of the air volume control device of the present invention.

[0097] like Figure 8 As shown, the air volume control device proposed in this embodiment of the invention includes:

[0098] The acquisition module 10 is used to acquire the current air outlet area of ​​the air conditioner when the air conditioner is in the swing mode.

[0099] In this embodiment, in the prior art, during the swing mode, the change in the angle of the air guide plate causes a change in the air outlet area of ​​the air conditioner. The air outlet area determines the air volume of the air conditioner; the larger the air outlet area, the greater the corresponding air volume. Therefore, the constantly changing air outlet area causes changes in the air volume of the air conditioner, resulting in different air volume at each moment during the swing process. Especially when the air outlet area is small, the air volume is severely reduced. In order to solve the above problems, this embodiment improves the structure of the air conditioner, such as... Figure 3 As shown. Among them, the impeller 1 is used to control the speed of the air conditioner fan, the telescopic device 2 is used to push out or cover the air outlet 5 of the dual-flow air guide plate 4, and the sliding device 3 realizes the up and down movement of the dual-flow air guide plate. The telescopic device 2 can change the distance between the dual-flow air guide plate 4 and the air conditioner, and the sliding device 3 can change the air outlet angle of the dual-flow air guide plate 4. The two work together to change the air outlet area of ​​the air conditioner.

[0100] It should be noted that this embodiment can adjust the air conditioner's operating mode according to user-input control commands. For example, based on a user-inputted swing command, the air conditioner's operating mode can be adjusted to swing mode. Furthermore, this embodiment can also set a preset time, and when the preset time is reached, the air conditioner's operating mode can be automatically adjusted to swing mode. This embodiment can also adjust the air conditioner's operating mode in other ways, and can be set accordingly according to actual conditions. This embodiment does not impose any limitations on this.

[0101] In specific implementation, the current air outlet area is the air outlet area corresponding to the air conditioner during swing operation. In this embodiment, the air outlet area corresponding to the air conditioner during swing operation can also be obtained based on the constant air volume command input by the user. Furthermore, in this embodiment, a preset time can also be set, and the air outlet area corresponding to the air conditioner during swing operation can be automatically obtained when the preset time is reached. In this embodiment, the air outlet area corresponding to the air conditioner during swing operation can also be obtained in other ways, and can be set accordingly according to the actual situation. This embodiment does not limit this.

[0102] Furthermore, the air outlet area of ​​the air conditioner is related to the air delivery angle of the dual-flow guide vane. After the air conditioner starts its swing mode, the air delivery angle of the dual-flow guide vane during the swing process is obtained, i.e., the current air delivery angle. Then, the air outlet area corresponding to the air conditioner during the swing operation can be calculated based on this air delivery angle. It should be emphasized that during the swing process, the upper and lower ends of the dual-flow guide vane and the air conditioner form a matrix-like shape. The air outlet area between the upper end of the dual-flow guide vane and the air conditioner, as well as the air outlet area between the lower end of the dual-flow guide vane and the air conditioner, can be approximated by calculating the area of ​​a matrix. Of course, other methods can also be used to calculate the air outlet area corresponding to the air outlet angle in this embodiment, which can be set according to the actual situation. This embodiment does not limit this.

[0103] The calculation module 20 is used to determine the air outlet area difference based on the current air outlet area and the preset air outlet area.

[0104] In this embodiment, after obtaining the air outlet area (current air outlet area) corresponding to the air conditioner during swing mode, the difference between the current air outlet area and the preset air outlet area is calculated to obtain the air outlet area difference. For example, if the current air outlet area is S1 and the preset air outlet area is S2, the air outlet area difference is S1-S2. The preset air outlet area is the air outlet area when the air conditioner is in swing mode. It can be calculated based on the corresponding air outlet angle when the air conditioner is in swing mode. Alternatively, the preset air outlet area can be calculated based on a preset air outlet angle set by the user when the air conditioner is in swing mode. Of course, the preset air outlet area can be calculated using the methods mentioned above, or other methods. This embodiment does not limit this method.

[0105] The query module 30 is used to determine the air volume difference based on the air outlet area difference.

[0106] In practice, after determining the difference in air outlet area, the difference in air volume (air volume difference) between the air conditioner when it starts swinging and during the swinging process at various times can be determined based on the determined difference in air outlet area.

[0107] It is important to emphasize that the air volume is related not only to the air outlet area but also to the fan speed. However, since the fan speed has not been adjusted in this case, it can be considered a fixed value. Therefore, the corresponding air volume difference can be directly obtained based on the correspondence between the air outlet area and the air volume difference. For example, if the air outlet area is S1, the corresponding air volume is B1; if the air outlet area is S2, the corresponding air volume is B2. Therefore, the air volume difference corresponding to the difference in air outlet areas S1-S2 is B1-B2. Furthermore, in this embodiment, other methods can be used to obtain the corresponding air volume difference based on the difference in air outlet areas. These methods can be set according to actual conditions, and this embodiment does not impose any restrictions on them.

[0108] The adjustment module 40 is used to adjust the fan speed of the air conditioner according to the air volume difference.

[0109] It should be noted that in this embodiment, the fan speed can be adjusted accordingly based on the air volume and speed curve, as shown in the figure below. Figure 4 As shown, Figure 4 In the middle, LA represents the relationship curve between air volume and rotational speed. For example, when the air velocity is 700 r / min, the corresponding air volume is 300 m³ / min. 3 / h, when the wind speed is 1100r / min, the corresponding air volume is 650m³ / h. 3 / h, based on the above data, the air volume difference is 350m³ / h. 3 When the wind speed is / h, the corresponding adjustment is 400r / min. Therefore, when the air volume difference is 350m3 At / h, increase the fan speed by 400r / min, with an air volume difference of -350m 3 When the air volume difference is / h, the fan speed is reduced by 400 r / min. It is easy to understand that in this embodiment, the fan speed corresponding to the air volume difference can also be determined according to other methods, and the choice can be made according to the actual situation. This embodiment does not impose any restrictions on this.

[0110] Furthermore, this embodiment also ensures that the noise level of the air conditioner remains stable, for example... Figure 4 As shown, Figure 4 The LB curve represents the relationship between airflow and noise. When the airflow is constant, the noise level can be kept relatively stable as well. For example, when the airflow is 308 m³ / h... 3 At a speed of / h, the corresponding noise level remained at 26.6dB, which is consistent with the noise level when the air volume is 778m³ / h. 3 At / h, the corresponding noise level remains at 43.6dB.

[0111] This embodiment obtains the current air outlet area of ​​the air conditioner when it is in swing mode; determines the air outlet area difference based on the current air outlet area and the preset air outlet area; determines the air volume difference based on the air outlet area difference; and adjusts the fan speed of the air conditioner based on the air volume difference. By determining the air volume difference through the air outlet area difference during the air conditioner's swing process and adjusting the fan speed of the air conditioner according to the air volume, the air volume of the air conditioner during the swing process is kept constant. The constant air volume makes the noise of the air conditioner stable during the up and down swing, thus improving the user experience.
