Description

Technical Field

[0001] This application relates to the field of smart home appliances, such as an air guide assembly, an air conditioner, and a method and apparatus for controlling the air conditioner. Background Technology

[0002] Air conditioners are generally equipped with a fresh air system, which is used to introduce fresh outdoor air into the room to improve the freshness of the indoor air and provide users with a comfortable indoor environment.

[0003] In related technologies, outdoor fresh air is mixed with indoor recirculated air before being released into the room through the air outlet of the air conditioner. The air outlet angle and volume can be adjusted by changing the angle of the air guide vane. The air guide vane is usually a single piece of material, and to quickly adjust indoor air freshness, it is generally adjusted to its maximum air outlet angle. At this point, the indoor unit's airflow is also at its maximum, which has a significant impact on indoor temperature, potentially causing discomfort to some users.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides an air guide assembly, an air conditioner, a method and apparatus for controlling the air conditioner, to reduce the discomfort caused to users by the air conditioner introducing outdoor fresh air into the room.

[0007] In some embodiments, the air guiding assembly includes: a first air guiding plate having a sub-air outlet extending through its thickness along its length; a first driving unit being driven to the first air guiding plate to drive the first air guiding plate to rotate; a second air guiding plate being disposed within the sub-air outlet along its length; and a second driving unit being driven to the second air guiding plate to drive the second air guiding plate to rotate within the sub-air outlet; wherein, when the second air guiding plate is not rotated, it forms a complete air guiding plate with the first air guiding plate.

[0008] In some embodiments, the air conditioner includes an air guide assembly as described above.

[0009] In some embodiments, the method for controlling an air conditioner includes: acquiring the concentration of carbon dioxide in the room; controlling the fresh air system to turn on when the concentration of carbon dioxide is greater than or equal to a first concentration threshold; and controlling the operation of a first air guide plate and a second air guide plate according to the concentration of carbon dioxide.

[0010] In some embodiments, the apparatus for controlling an air conditioner includes a processor and a memory storing program instructions, the processor being configured to execute the aforementioned method for controlling an air conditioner when the program instructions are executed.

[0011] The air guide assembly, air conditioner, method and apparatus for controlling the air conditioner provided in the embodiments of this disclosure can achieve the following technical effects:

[0012] The first air guide plate can be independently rotated by a first drive unit, and the second air guide plate can be independently rotated by a second drive unit. Simultaneously, the second air guide plate is installed inside the sub-air outlet of the first air guide plate. Therefore, when the first and second air guide plates rotate, they create air outlets of different sizes. Thus, when the air conditioner's fresh air system is activated, the rotation of either the first or second air guide plate can be controlled according to the environment, thereby adjusting the size of the indoor unit's air outlet, reducing the impact of introducing fresh air into the room on indoor temperature and user comfort, and improving the user experience.

[0043] Combination Figure 1 and Figure 2 As shown, this embodiment of the disclosure provides an air guiding assembly 1, including: a first air guiding plate 10, a first driving part 20, a second air guiding plate 30, and a second driving part 40. A sub-air outlet 11 is provided on the first air guiding plate 10. The sub-air outlet 11 is disposed along the length direction of the first air guiding plate 10 and extends through the thickness direction of the first air guiding plate 10. The sub-air outlet 11 is elongated. See also... Figure 2 The first drive unit 20 is driven to one end of the first air guide plate 10 along its length to drive the first air guide plate 10 to rotate. The second air guide plate 30 is disposed within the sub-air outlet 11 along its length, and the second drive unit 40 is driven to one end of the second air guide plate 30 along its length to drive the second air guide plate 30 to rotate within the sub-air outlet 11. The size of the second air guide plate 30 matches the size of the sub-air outlet 11. When the second air guide plate 30 is not rotated, it and the first air guide plate 10 form a complete air guide plate, equivalent to the second air guide plate 30 being embedded within the first air guide plate 10. When this air guide assembly 1 is installed in the indoor unit of an air conditioner, if the first drive unit 20 drives the first air guide plate 10 to rotate, the original air outlet of the indoor unit becomes the air outlet. If the second drive unit 40 drives the second air guide plate 30 to rotate, the sub-air outlet 11 becomes the air outlet.

[0044] Using the air guide assembly 1 provided in this embodiment, the first air guide plate 10 can be independently rotated by the first driving unit 20, and the second air guide plate 30 can be independently rotated by the second driving unit 40. Simultaneously, the second air guide plate 30 is installed within the sub-air outlet 11 of the first air guide plate 10. Therefore, when the first air guide plate 10 and the second air guide plate 30 rotate, they form air outlets of different sizes. Thus, when the air conditioner's fresh air system is turned on, the rotation of the first air guide plate 10 or the second air guide plate 30 can be controlled according to the environment, thereby adjusting the size of the indoor unit's air outlet, reducing the impact of introducing fresh air into the room on indoor temperature and user comfort, and improving the user experience.

[0045] Optionally, the rotation axis of the first air guide plate 10 is parallel to the length direction of the first air guide plate 10. The rotation axis of the second air guide plate 30 is parallel to the length direction of the second air guide plate 30.

[0046] Optionally, the flipping axes of the first air guide plate 10 and the second air guide plate 30 are the same axis.

[0047] Optionally, the first drive unit 20 is disposed on the casing of the indoor unit of the air conditioner.

[0048] Optionally, the second drive unit 40 is disposed on the inner side of the first air guide plate 10. When the first air guide plate 10 is not rotated, it is closed at the air outlet of the indoor unit. At this time, the side of the first air guide plate 10 facing the inside of the casing is the inner side of the first air guide plate 10. In this way, the first air guide plate 10 can rotate along with the second air guide plate 30 and the second drive unit 40, thereby avoiding the positional conflict between the second air guide plate 30 and the second drive unit 40 when the first air guide plate 10 rotates along with the second air guide plate 30 if the second drive unit 40 is not disposed on the first air guide plate 10, which would prevent the first air guide plate 10 from rotating normally.

[0049] Optionally, the first air guide plate 10 and the second air guide plate 30 can be selectively controlled to rotate. That is, when the first drive unit 20 drives the first air guide plate 10 to rotate, the second air guide plate 30 closes at the sub-air outlet 11 (the second air guide plate 30 does not rotate). When the second drive unit 40 drives the second air guide plate 30 to rotate, the first air guide plate 10 closes at the air outlet of the indoor unit (the first air guide plate 10 does not rotate). In this way, selectively controlling either the first air guide plate 10 or the second air guide plate 30 to rotate can form air outlets of different sizes, thereby adjusting the airflow.

[0050] Combination Figures 1 to 4 As shown, the first air guide plate 10 includes: a first plate body 12, a first connecting portion 13, and a first transmission portion 14. The sub-air outlet 11 is arranged along the length direction of the first plate body 12 and extends through the thickness direction of the first plate body 12. See also... Figure 1 and 3 The first connecting portion 13 is located at a first position inside the first plate 12 and is rotatably mounted on the casing of the indoor unit of the air conditioner. Optionally, the first position is the first end near the length direction of the first plate 12. Figure 1 (As shown on the right end), and located inside the first plate 12. See also Figure 1 , Figure 2 and Figure 4 The first transmission part 14 is disposed at a second position inside the first plate 12 and is connected to the first drive part 20 in a transmission manner. Optionally, the second position and the first position are two positions opposite each other in the length direction of the first plate 12. Optionally, the second position is the second end in the length direction of the first plate 12. Figure 1 (as shown on the left end), and located inside the first plate 12.

[0051] In this way, the first drive unit 20 transmits the driving force for rotating the first air guide plate 10 to the first transmission unit 14, and the first transmission unit 14 drives the first air guide plate 10 to rotate. The first position of the first air guide plate 10 is rotatably set on the casing of the indoor unit through the first connecting part 13, so that both ends of the first air guide plate 10 have support points in the length direction, thereby making the rotation of the first air guide plate 10 more stable.

[0052] Optionally, combined Figure 3 As shown, the first connecting part 13 includes a first base 131 and a first rotating shaft 132. The first base 131 is erected in a first position. Optionally, the first base 131 has a first side and a second side, the first side facing the direction of the first transmission part 14, and the second side flush with the end face of the first end of the first plate 12. The first end of the first rotating shaft 132 is connected to the second side of the first base 131, and the second end of the first rotating shaft 132 is rotatably inserted into the housing of the indoor unit.

[0053] In this way, the first air guide plate 10 is rotatably connected to the casing of the indoor unit through the first base 131 and the first rotating shaft 132.

[0054] Optionally, combined Figure 4 As shown, the first transmission part 14 includes a second base 141 and a second connecting part 142. The second base 141 is erected in a second position. Optionally, the second base 141 has a third side and a fourth side, the third side facing the direction of the first connecting part 13, and the fourth side flush with the end face of the second end of the first plate 12. The second connecting part 142 is connected to the fourth side of the second base 141. See also Figure 6 The second connecting part 142 is provided with a first insertion hole 143. The power output shaft of the first driving part 20 is inserted into the first insertion hole 143, and then drives the first air guide plate 10 to rotate through the first transmission part 14.

[0055] Optionally, combined Figure 4 and Figure 5 As shown, the second connecting part 142 is a columnar body. The first end of the columnar body is connected to the fourth side surface of the second base 141, and the end face of the second end of the columnar body is recessed into the interior of the columnar body to form a first insertion hole 143.

[0056] Optionally, combined Figure 6As shown, the cross-sectional shape of the first insertion hole 143 is polygonal. Correspondingly, the cross-sectional shape of the power output shaft of the first drive unit 20 is also polygonal, and the number of sides is equal to the number of sides of the cross-section of the first insertion hole 143. In this way, when the power output shaft of the first drive unit 20 is inserted into the first insertion hole 143, the first insertion hole 143 can restrict the degree of freedom of the power output shaft of the first drive unit 20, preventing the power output shaft of the first drive unit 20 from rotating within the first insertion hole 143, thereby causing the first drive unit 20 to drive the first air guide plate 10 to rotate.

[0057] Optionally, see again Figure 4 The third side of the second base 141 has one or more openwork structures 144 to save material while providing sufficient support.

[0058] Optionally, the first drive unit 20 includes a first drive motor 21.

[0059] Combination Figure 2 As shown, the second drive unit 40 includes a second drive motor 41. The second drive motor 41 is disposed inside the first air guide plate 10, that is, inside the first plate body 12. The power output shaft of the second drive motor 41 is connected to the second air guide plate 30 for driving the second air guide plate 30 to rotate.

[0060] Optionally, see again Figure 2 The second drive unit 40 also includes a mounting housing 42. The mounting housing 42 is disposed inside the first air guide plate 10, and the power output shaft 411 of the second drive motor 41 passes through the wall of the mounting housing 42 for transmission connection with the second air guide plate 30. The mounting housing 42 can provide protection for the second drive motor 41, preventing the second drive motor 41 from being directly exposed to the environment, and is also more aesthetically pleasing.

[0061] Optionally, see again Figure 3 An installation platform 15 protrudes from the inner side of the first air guide plate 10, and the installation housing 42 is mounted on the installation platform 15. This avoids the problem of reduced rigidity of the first plate 12 caused by drilling or other operations required to directly mount the installation housing 42 onto the first plate 12.

[0062] Optionally, a groove 151 is provided on the side of the mounting platform 15 facing the interior of the indoor unit's casing. Correspondingly, a strip-shaped protrusion is provided on one outer wall of the mounting housing 42, which is slidably inserted into the groove 151. This facilitates the assembly and disassembly of the second drive unit 40.

[0063] Optionally, see [link to relevant documentation] Figure 2 The second air guide plate 30 includes: a second plate body 31. The first end of the second plate body 31 ( Figure 2The end face of the left end (shown) is connected to one end of the second rotating shaft 32. A second insertion hole is provided on the inner wall of the sub-air outlet 11, corresponding to the first end of the second plate 31, and the second rotating shaft 32 is rotatably inserted into the second insertion hole. In this way, the second air guide plate 30 and the first air guide plate 10 are rotatably connected through the second rotating shaft 32.

[0064] The second end of the second plate 31 ( Figure 2 A third insertion hole is provided along the length of the second plate 31 (as shown on the right end). The power output shaft 411 of the second drive unit 40 is inserted into the third insertion hole to drive the second plate 31 to rotate.

[0065] Combination Figure 7 As shown, this embodiment of the present disclosure provides an indoor unit 2. The indoor unit 2 includes a housing 201 and the aforementioned air guide assembly 1. The housing 201 is provided with an air outlet, and the air guide assembly 1 is disposed at the air outlet. Optionally, a fourth insertion hole is provided on the housing 201 at a position corresponding to the second end of the first rotating shaft 132 of the air guide assembly 1, and the second end of the first rotating shaft 132 is inserted into the fourth insertion hole. A first drive unit 20 is disposed on the housing 201.

[0066] Combination Figure 8 As shown, this embodiment of the present disclosure provides an air conditioner 4, including an outdoor unit 3 and the indoor unit 2 described above.

[0067] Based on the above air conditioner, combined with Figure 9 As shown, this disclosure provides a method for controlling an air conditioner, including:

[0068] S101, the processor obtains the indoor carbon dioxide concentration.

[0069] S102, the processor controls the fresh air system to start when the carbon dioxide concentration is greater than or equal to the first concentration threshold.

[0070] S103, the processor controls the operation of the first and second air guide plates according to the concentration of carbon dioxide.

[0071] The air conditioner is equipped with a carbon dioxide concentration sensor. The air conditioner's processor communicates with the carbon dioxide concentration sensor to obtain the indoor carbon dioxide concentration C. It determines the value of C; if C1 ≤ C, C1 is the first concentration threshold. If the carbon dioxide concentration continues to rise at this point, it will be detrimental to the user's work and study. Therefore, the fresh air system is activated to fully mix outdoor fresh air with indoor air before releasing it into the room through the air conditioner's outlet. Simultaneously, based on the carbon dioxide concentration, the operation of the first and second air guide vanes is controlled. As mentioned earlier, the air conditioner's outlet can be the original outlet of the indoor unit's casing or a sub-outlet. Different outlet sizes result in different air volumes under the same conditions, thus affecting the amount of fresh air introduced into the room. Therefore, by controlling the operation of the first and second air guide vanes, the air outlet that matches the current carbon dioxide concentration can be selected.

[0072] The method for controlling an air conditioner provided in this disclosure involves controlling the activation of a fresh air system when the indoor carbon dioxide concentration is greater than or equal to a first concentration threshold. This introduces fresh outdoor air into the room, reducing or maintaining the carbon dioxide concentration. Simultaneously, the operation of the first and second air guide vanes is controlled based on the carbon dioxide concentration, ensuring that the air outlet selection of the air conditioner matches the current carbon dioxide concentration. Combined with the fresh air system, this ensures that the airflow, after mixing with indoor air, can quickly reduce the carbon dioxide concentration while minimizing discomfort caused by excessive airflow. This achieves a balance between improving indoor air freshness and enhancing the user experience.

[0073] Combination Figure 10 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0074] S101, the processor obtains the indoor carbon dioxide concentration.

[0075] S102, the processor controls the fresh air system to start when the carbon dioxide concentration is greater than or equal to the first concentration threshold.

[0076] S113, when the carbon dioxide concentration is greater than or equal to the first concentration threshold and less than or equal to the second concentration threshold, the processor controls the second air guide plate to flip to the corresponding target position; wherein, the target position of the second air guide plate corresponds to the operating mode of the air conditioner.

[0077] S123, the processor adjusts the operation of the first and second air guide plates according to the changes in carbon dioxide concentration.

[0078] When C1 ≤ C, and if C1 ≤ C ≤ C2, where C2 is the second concentration threshold, this indicates that the carbon dioxide concentration is conducive to keeping the user alert and suitable for work and study. Therefore, the second air guide vane is controlled to rotate to the corresponding target position. When the second air guide vane rotates, the sub-vent acts as an air outlet. Since the outlet is small, its output airflow has minimal impact on the carbon dioxide concentration. This maintains the carbon dioxide concentration at the current level, thus preserving a suitable indoor environment for the user. Furthermore, due to the small outlet size, the airflow will not be excessive, ensuring a comfortable experience for the user and preventing discomfort caused by excessive airflow.

[0079] The target position of the second air guide plate corresponds to the current operating mode of the air conditioner. Optionally, if the air conditioner is in cooling mode, the target position of the second air guide plate is horizontal to utilize the characteristic that cold air tends to sink, thus achieving a canopy-like airflow for cooling. If the air conditioner is in heating mode, the target position of the second air guide plate is vertical to utilize the characteristic that hot air tends to rise, thus achieving a carpet-like airflow for heating.

[0080] At the same time, the first air guide plate is controlled to close at the air outlet, that is, the first air guide plate does not rotate.

[0081] Subsequently, the changes in carbon dioxide concentration are continuously monitored to determine whether the carbon dioxide concentration has decreased or continued to rise, and then the operation of the first and second air guides is adjusted to adapt to the changes in carbon dioxide concentration.

[0082] Optionally, C1 is set to 800 ppm and C2 is set to 1000 ppm.

[0083] Combination Figure 11 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0084] S101, the processor obtains the indoor carbon dioxide concentration.

[0085] S102, the processor controls the fresh air system to start when the carbon dioxide concentration is greater than or equal to the first concentration threshold.

[0086] S113, when the carbon dioxide concentration is greater than or equal to the first concentration threshold and less than or equal to the second concentration threshold, the processor controls the second air guide plate to flip to the corresponding target position; wherein, the target position of the second air guide plate corresponds to the operating mode of the air conditioner.

[0087] S1123, if the carbon dioxide concentration increases and exceeds the second concentration threshold after the first set time, the processor adjusts the second air guide plate to flip to the corresponding initial position and adjusts the first air guide plate to flip to the corresponding target position; wherein, the initial position of the second air guide plate is the position when the second air guide plate is not flipped; the target position of the first air guide plate corresponds to the operating mode of the air conditioner.

[0088] When the fresh air system is turned on and the second air guide plate flips to the corresponding target position, the processor controls the timing module to start timing. After running for the first set time, if the carbon dioxide concentration increases and exceeds the second concentration threshold C2, it indicates that too little outdoor fresh air is being introduced, and the carbon dioxide concentration is not being maintained at a suitable level. Therefore, at this time, the second air guide plate is adjusted to flip back to its corresponding initial position. Here, the initial position of the second air guide plate is the position when the second air guide plate is flipped, that is, controlling the second air guide plate to close at the sub-air vent, becoming one with the first air guide plate. At the same time, the first air guide plate is adjusted to flip back to the corresponding target position. When the first air guide plate flips to the corresponding target position, the original air outlet of the casing becomes the air outlet, with a larger air outlet space than the sub-air vent, resulting in a larger air volume and faster adjustment of the carbon dioxide concentration.

[0089] The target position of the first air guide vane corresponds to the current operating mode of the air conditioner. Optionally, if the air conditioner is in cooling mode, the target position of the first air guide vane is horizontal. If the air conditioner is in heating mode, the target position of the first air guide vane is vertical. The principle is the same as above, and will not be repeated here.

[0090] Optionally, the first set duration is 10 minutes.

[0091] Combination Figure 12 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0092] S101, the processor obtains the indoor carbon dioxide concentration.

[0093] S102, the processor controls the fresh air system to start when the carbon dioxide concentration is greater than or equal to the first concentration threshold.

[0094] S113, when the carbon dioxide concentration is greater than or equal to the first concentration threshold and less than or equal to the second concentration threshold, the processor controls the second air guide plate to flip to the corresponding target position; wherein, the target position of the second air guide plate corresponds to the operating mode of the air conditioner.

[0095] S1123, if the concentration of carbon dioxide increases and is greater than the second concentration threshold within the set duration, the processor adjusts the second air deflector to flip to the corresponding initial position and adjusts the first air deflector to flip to the corresponding target position; wherein, the initial position of the second air deflector is the position when the second air deflector is not flipped; the target position of the first air deflector corresponds to the operation mode of the air conditioner.

[0096] S1223, if the concentration of carbon dioxide decreases and is less than the third concentration threshold, the processor adjusts the first air deflector to flip to the corresponding initial position and adjusts the second air deflector to flip to the corresponding target position; wherein, the initial position of the first air deflector is the position when the first air deflector is not flipped.

[0097] After the second air deflector is closed and the first air deflector flips to the corresponding target position, if the concentration of carbon dioxide decreases and C < C3, where C3 is the third concentration threshold, it means that the concentration of carbon dioxide has decreased to a relatively low level and the indoor air is relatively clean. Therefore, at this time, the first air deflector is adjusted to flip to the corresponding initial position. Here, the initial position of the first air deflector is the position when the first air deflector is not flipped, that is, the first air deflector is controlled to close at the air outlet of the casing. At the same time, the second air deflector is adjusted to flip to the corresponding target position to use the sub-air outlet as the air outlet. In this way, when the concentration of carbon dioxide has decreased to a relatively low level, the positions of the first air deflector and the second air deflector are adjusted to use the sub-air outlet with a smaller air outlet space as the air outlet, thereby making the air volume of the air conditioner smaller. In this way, the concentration of carbon dioxide can be maintained at a relatively low level and the discomfort caused by excessive air volume to the user can be avoided.

[0098] Optionally, C3 is set to 700 ppm. [[ID=1!]]

[0099] Combined Figure 13 As shown, the embodiments of the present disclosure provide another method for controlling an air conditioner, including:

[0100] S101, the processor obtains the concentration of carbon dioxide in the room.

[0101] S102, when the concentration of carbon dioxide is greater than or equal to the first concentration threshold, the processor controls the fresh air system to start.

[0102] S103, the processor controls the operation of the first air deflector and the second air deflector according to the concentration of carbon dioxide.

[0103] S104, if the concentration of carbon dioxide is less than the third concentration threshold within the second set duration, the processor controls the fresh air system to close.

[0104] After a series of adjustments to the first air deflector and the second air deflector in the above S113, S1123, and S1223, if C < C3 is always maintained within the second set duration, it indicates that the carbon dioxide concentration can be maintained at a relatively optimal level for a long time, and there is no need to continue introducing fresh air into the room. Therefore, at this time, the fresh air system is controlled to be turned off. In this way, when it is not necessary to turn on the fresh air system, the fresh air system can be turned off in a timely manner to save energy.

[0105] Optionally, the second set duration is 15 minutes.

[0106] Combined with Figure 14 As shown, the embodiment of the present disclosure provides another method for controlling an air conditioner, including:

[0107] S101, the processor obtains the concentration of carbon dioxide in the room.

[0108] S102, when the concentration of carbon dioxide is greater than or equal to the first concentration threshold, the processor controls the fresh air system to be turned on.

[0109] S103, the processor controls the operation of the first air deflector and the second air deflector according to the concentration of carbon dioxide.

[0110] S105, the processor controls the air outlet wind speed and / or the fresh air gear according to the concentration of carbon dioxide.

[0111] S104, if the concentration of carbon dioxide is less than the third concentration threshold within the second set duration, the processor controls the fresh air system to be turned off.

[0112] After the fresh air system is turned on, while controlling the first air deflector and the second air deflector, the air outlet wind speed and / or the fresh air gear of the air conditioner can also be controlled according to the concentration of carbon dioxide, so as to cooperate with the positions of the first air deflector and the second air deflector to control the air volume of the mixed air (the air outlet formed after the outdoor fresh air and the indoor air are mixed) entering the room, taking into account both the adjustment of the carbon dioxide concentration and the guarantee of the user's body feeling.

[0113] Optionally, S105, the processor controls the air outlet wind speed according to the concentration of carbon dioxide, including:

[0114] When the concentration of carbon dioxide is greater than or equal to the first concentration threshold and less than or equal to the second concentration threshold, the processor controls the air outlet wind speed to be the first wind speed.

[0115] When the concentration of carbon dioxide rises and is greater than the second concentration threshold, the processor controls the air outlet wind speed to be the second wind speed.

[0116] When the concentration of carbon dioxide drops and is less than the third concentration threshold, the processor controls the air outlet wind speed to be the third wind speed.

[0117] Among them, the third concentration threshold is less than the first concentration threshold; the second wind speed is greater than the first wind speed and also greater than the third wind speed.

[0118] If C1≤C≤C2, and the positions of the first and second air guides are controlled, the air outlet speed is set to a lower first air velocity. As mentioned earlier, in this case, the second air guide is open and the first air guide is closed, resulting in a smaller air volume from the indoor unit. Therefore, a lower first air velocity is used to maintain the carbon dioxide concentration at the current level while also considering the user's comfort.

[0119] Subsequently, if the carbon dioxide concentration increases instead of decreasing, and C2 ≤ C, the outlet air velocity is controlled to a higher second air velocity. As mentioned earlier, at this time, the first air guide plate is open and the second air guide plate is closed, resulting in a larger air volume from the indoor unit. Therefore, a higher second air velocity is matched to quickly adjust the carbon dioxide concentration. Optionally, the indoor unit's louvers are also controlled to swing left and right to enhance indoor airflow circulation and further improve the rate of carbon dioxide concentration adjustment.

[0120] Afterwards, the carbon dioxide concentration is continuously monitored. If, after the above control measures, the carbon dioxide concentration decreases and C≤C3, the air outlet speed is controlled to a lower third air speed. As mentioned earlier, at this time, the second air guide plate is open and the first air guide plate is closed, resulting in a smaller air volume from the indoor unit. Therefore, a lower third air speed is matched to achieve a balance between carbon dioxide concentration and user comfort.

[0121] Optionally, the first wind speed is 2 m / s, the second wind speed is 4 m / s, and the third wind speed is 2 m / s.

[0122] Optionally, in S105, the processor controls the fresh air level based on the carbon dioxide concentration, including:

[0123] When the carbon dioxide concentration is greater than or equal to the first concentration threshold and less than or equal to the second concentration threshold, the processor controls the fresh air level to the first level.

[0124] When the carbon dioxide concentration rises and exceeds the second concentration threshold, the processor controls the fresh air setting to the second level.

[0125] When the carbon dioxide concentration decreases and falls below the third concentration threshold, the processor controls the fresh air setting to the third level.

[0126] Among them, the third concentration threshold is less than the first concentration threshold; the second level is greater than the first level and greater than the third level.

[0127] If C1≤C≤C2, and the positions of the first and second air guides are controlled, the fresh air setting is set to the first setting of the medium setting. As mentioned earlier, at this time, the second air guide is open and the first air guide is closed, resulting in a smaller air volume output from the indoor unit. Therefore, a lower fresh air setting is used to maintain the carbon dioxide concentration at the current level while also considering the user's comfort.

[0128] Subsequently, if the carbon dioxide concentration increases instead of decreasing, and C2 ≤ C, the fresh air setting is adjusted to the second highest setting. As mentioned earlier, at this time, the first air guide vane is open and the second air guide vane is closed, resulting in a larger airflow from the indoor unit. Therefore, a higher fresh air setting is appropriate to quickly adjust the carbon dioxide concentration. Optionally, the indoor unit's louvers can also be controlled to swing left and right to enhance indoor airflow circulation and further improve the rate of carbon dioxide concentration adjustment.

[0129] Afterwards, the carbon dioxide concentration is continuously monitored. If, after the above control measures, the carbon dioxide concentration decreases and C≤C3, the fresh air setting is adjusted to the third low setting. As mentioned earlier, at this point, the second air guide plate is open and the first air guide plate is closed, resulting in a smaller airflow from the indoor unit. Therefore, a lower fresh air setting is used to balance the carbon dioxide concentration and the user's comfort.

[0130] Combination Figure 15 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0131] S101, the processor obtains the indoor carbon dioxide concentration.

[0132] S102, the processor controls the fresh air system to start when the carbon dioxide concentration is greater than or equal to the first concentration threshold.

[0133] S103, the processor controls the operation of the first and second air guide plates according to the concentration of carbon dioxide.

[0134] S106, the processor controls the outlet air speed and heat exchange temperature, or the fresh air setting and heat exchange temperature, or the outlet air speed, fresh air setting and heat exchange temperature, based on the carbon dioxide concentration.

[0135] S104, if the carbon dioxide concentration is less than the third concentration threshold within the second set time period, the processor controls the fresh air system to shut down.

[0136] As mentioned earlier, after the fresh air system is turned on, the airflow speed and / or fresh air setting of the air conditioner can be controlled according to the carbon dioxide concentration to coordinate with the positions of the first and second air guide vanes. Changes in the airflow speed and / or fresh air setting mean changes in the amount of fresh air entering the room, which affects the indoor temperature. Therefore, while adjusting the airflow speed and / or fresh air setting, the heat exchange temperature can also be adjusted. By adjusting the heat exchange temperature, the impact of changes in the airflow speed and / or fresh air setting on the indoor temperature can be offset, reducing indoor temperature fluctuations and thus improving user comfort.

[0137] Optionally, S106, the processor controls the heat exchange temperature based on the carbon dioxide concentration, including:

[0138] When the concentration of carbon dioxide is greater than or equal to a first concentration threshold and less than or equal to a second concentration threshold, the processor controls the heat exchange temperature to a first cooling temperature or a first heating temperature.

[0139] When the concentration of carbon dioxide rises and exceeds a second concentration threshold, the processor controls the heat exchange temperature to either a second cooling temperature or a second heating temperature.

[0140] When the carbon dioxide concentration decreases and falls below the third concentration threshold, the processor controls the heat exchange temperature to either the third cooling temperature or the third heating temperature.

[0141] Among them, the third concentration threshold is less than the first concentration threshold; the second cooling temperature is less than the first cooling temperature and less than the third cooling temperature; the second heating temperature is greater than the first heating temperature and greater than the third heating temperature.

[0142] When controlling the positions of the first and second air guide vanes, if C1 ≤ C ≤ C2, and the air conditioner is operating in cooling mode, the heat exchange temperature is controlled at a lower first cooling temperature. This is because, as mentioned earlier, the indoor unit's airflow is small and / or the fresh air fan speed is low, resulting in a small amount of high-temperature outdoor fresh air being introduced. Therefore, excessive temperature compensation is not required, and the heat exchange temperature is controlled at a relatively low first cooling temperature. If the air conditioner is operating in heating mode, the heat exchange temperature is controlled at a higher first heating temperature. Similarly, a small amount of low-temperature outdoor fresh air is introduced, and excessive temperature compensation is not required, thus the heat exchange temperature is controlled at a relatively high first heating temperature. Optionally, the first cooling temperature is set to 23℃, and the first heating temperature is set to 25℃.

[0143] After that, if the concentration of carbon dioxide does not decrease but increases, and C2≤C, and if the operating mode of the air conditioner is the cooling mode at this time, then control the heat exchange temperature to a lower second cooling temperature. This is because, as described above, at this time, the air volume of the indoor unit is relatively large and / or the fresh air gear is relatively high, introducing more high-temperature outdoor fresh air, and more temperature compensation is required. Therefore, control the heat exchange temperature to a lower second cooling temperature. If the operating mode of the air conditioner is the heating mode at this time, then control the heat exchange temperature to a higher second heating temperature. Similarly, at this time, more low-temperature outdoor fresh air is introduced, and more temperature compensation is required. Therefore, control the heat exchange temperature to a relatively higher second heating temperature. Optionally, the second cooling temperature is 20°C, and the second heating temperature is 27°C.

[0144] After that, continuously monitor the concentration of carbon dioxide. If, after the above control, the concentration of carbon dioxide decreases and C≤C3, and at this time the air volume of the indoor unit is relatively small and / or the fresh air gear is relatively low, and if the operating mode of the air conditioner is the cooling mode at this time, then control the heat exchange temperature to a lower third cooling temperature to perform a small amount of temperature compensation. If the operating mode of the air conditioner is the heating mode at this time, then control the heat exchange temperature to a higher third heating temperature to perform a small amount of temperature compensation. Optionally, the third cooling temperature is 22°C, and the third heating temperature is 26°C.

[0145] Optionally, when C<C₄, where C₄ is the fourth concentration threshold, generally there is no one in the room at this time, then control the fresh air system to close.

[0146] Optionally, when C₄≤C≤C₁, generally there is no one in the room at this time, then control the fresh air system to remain in the standby state. At the same time, control the sterilization module to turn on and irradiate the evaporator to prevent bacteria from generating. At the same time, control the ion module to turn on. The ion module effectively sterilizes and removes odors by ionizing water molecules in the air. Optionally, C₄ is 500 ppm.

[0147] The following will specifically illustrate this embodiment with examples:

[0148] The air conditioner is equipped with a CO₂ concentration sensor, and the concentration value is displayed in real time on the screen in the lower right corner of the air conditioner through the AI algorithm, intuitively reflecting the current air quality situation.

[0149] ① When the indoor CO₂ concentration is below 500 ppm, the processor of the air conditioner automatically closes the fresh air system, and the air conditioner does not need to be turned on. The user can remotely and freely set the operating mode and parameters of the air conditioner through a smart device.

[0150] ② When the indoor CO2 concentration is between 500ppm and 800ppm, the air conditioner's processor puts the fresh air system into standby mode and activates the UVC sterilization module to irradiate the evaporator, preventing bacterial growth. Simultaneously, it activates the ionization module to sterilize and deodorize by ionizing water molecules in the air. Users can remotely set the air conditioner's operating mode and parameters via smart devices.

[0151] ③ Air conditioner operating in cooling mode:

[0152] (I) When the indoor CO2 concentration is between 800ppm and 1000ppm, it helps users stay alert and is suitable for studying or working. The air conditioner's processor controls the second air deflector to open and rotate to a position parallel to the ceiling, with the cooling temperature at 23℃ and the airflow speed at 2m / s. Simultaneously, the fresh air mode is activated at the medium setting, fully mixing the outdoor fresh air with the indoor air before releasing it together through the air outlet.

[0153] (II) After running for 10 minutes, if the above operation process does not reduce the CO2 concentration, but instead causes the CO2 concentration to exceed 1000ppm, the air conditioner's processor will control the second air guide plate to automatically return to the first air guide plate, merging the two into one. At the same time, the first air guide plate will be opened and rotated to a position parallel to the ceiling, the cooling temperature will be 20℃, the air outlet speed will be 4m / s, the direction of the oscillating blades will be adjusted to swing left and right, and the fresh air setting will be adjusted to high to enhance the indoor airflow circulation disturbance, so that the CO2 concentration returns to the normal value.

[0154] (III) After the indoor CO2 concentration decreases to 500-700 ppm, the air conditioner's processor controls the first air guide vane to close to the air outlet of the unit. At the same time, it controls the second air guide vane to open and rotate to a position parallel to the ceiling, setting the cooling temperature to 22°C and the air outlet velocity to 2 m / s. Simultaneously, the fresh air setting is adjusted to low.

[0155] (IV) After that, when the CO2 concentration does not exceed 700 ppm within 15 minutes, the air conditioner's processor controls the fresh air system to shut down.

[0156] ④ Air conditioner operating heating mode:

[0157] (I) When the indoor CO2 concentration is between 800ppm and 1000ppm, the air conditioner's processor controls the second air guide plate to open and rotate to a vertical position, with the heating temperature at 25℃ and the air outlet speed at 2m / s. Simultaneously, the fresh air mode is activated, with the fresh air setting at medium, to fully mix the outdoor fresh air with the indoor air and release them together through the air outlet.

[0158] (II) After running for 10 minutes, if the above operation process does not reduce the CO2 concentration, but instead causes the CO2 concentration to exceed 1000ppm, the air conditioner's processor will control the second air guide plate to automatically return to the first air guide plate, merging the two into one. At the same time, the first air guide plate will be opened and rotated to a vertical position, the heating temperature will be 28℃, the air outlet speed will be 4m / s, the direction of the oscillating blades will be adjusted to swing left and right, and the fresh air setting will be adjusted to the highest setting to enhance the indoor airflow circulation disturbance, so that the CO2 concentration returns to the normal value.

[0159] (III) After the indoor CO2 concentration decreases to 500-700ppm, the air conditioner's processor controls the first air guide plate to close to the air outlet of the unit casing. At the same time, it controls the second air guide plate to open and flip to a vertical position, setting the heating temperature to 26℃ and the air outlet velocity to 2m / s. Simultaneously, the fresh air setting is adjusted to low.

[0160] (IV) After that, when the CO2 concentration does not exceed 700 ppm within 15 minutes, the air conditioner's processor controls the fresh air system to shut down.

[0161] Combination Figure 16 As shown, this embodiment of the disclosure provides a device 160 for controlling an air conditioner, including: an acquisition module 161, a first control module 162, and a second control module 163. The acquisition module 161 is configured to acquire the concentration of carbon dioxide in the room. The first control module 162 is configured to control the activation of a fresh air system when the carbon dioxide concentration is greater than or equal to a first concentration threshold. The second control module 163 is configured to control the operation of a first air guide plate and a second air guide plate based on the carbon dioxide concentration.

[0162] Using the device 160 for controlling an air conditioner provided in this embodiment, when the indoor carbon dioxide concentration is greater than or equal to a first concentration threshold, the fresh air system is activated to introduce outdoor fresh air into the room, thereby reducing or maintaining the carbon dioxide concentration. Simultaneously, the operation of the first and second air guide vanes is controlled based on the carbon dioxide concentration, ensuring that the selection of the air conditioner's air outlet matches the current carbon dioxide concentration. Combined with the fresh air system, this ensures that the airflow after the outdoor fresh air mixes with the indoor air before being blown into the room can both quickly reduce the carbon dioxide concentration and reduce discomfort caused to the user by excessive airflow. Thus, a balance is achieved between improving indoor air freshness and enhancing the user experience.
