[0057] Figure 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention, referring to Figures 2 to 5 In the control method of the air conditioner of the embodiment of the present invention, the air conditioner includes two air outlets 10, the two air outlets 10 are arranged in a horizontal direction, and the front side of each air outlet 10 is provided with a first air outlet and a second air outlet extending in the length direction of the air outlet 10, and the first air outlet is close to the other air outlet 10. The second air outlet 10 is arranged at an interval with the first air outlet 10, so that an air induction interval 20 is formed between the second air outlet 10 and the first air outlet 10. The control method of the air conditioner includes obtaining the indoor ambient temperature and whether there is a person within a preset distance in front of the air induction interval 20. When the difference between the indoor ambient temperature and the set temperature is greater than the first preset difference, and there is a person within the preset distance in front of the air induction interval 20, the position of the user relative to the air induction interval 20 is obtained. According to the position of the user relative to the air induction interval 20, the air outlet direction, air volume and air outlet speed of the first air outlet and the second air outlet of at least one air outlet 10 are controlled.

[0058] When the air conditioner is working, the airflow of each air outlet 10 is blown out through the first air outlet and the second air outlet. When at least one of the two first air outlets blows out a forward airflow, it can drive the indoor air in the induced draft interval 20 to flow forward and mix together, so that the temperature of the mixed airflow is closer to the room temperature, making the mixed airflow softer. The air conditioner can prevent users at any position in front of the induced draft interval 20 from being directly blown by the airflow blown by the air conditioner by controlling the air outlet direction, air volume and air outlet speed of the first air outlet and the second air outlet of at least one air outlet 10, thereby improving the user experience and avoiding physical discomfort of the user.

[0059] Of course, in other embodiments of the present invention, the air outlet direction and air volume of the first air outlet and the second air outlet of at least one air outlet portion 10 can be controlled, or the air outlet direction and air outlet speed of the first air outlet and the second air outlet of at least one air outlet portion 10 can be controlled according to the user's position relative to the air induced gap 20.

[0060] Further, in some embodiments of the present invention, the first preset difference is 2° C. to 5° C., preferably, the first preset difference is 3° C. The front preset distance is 0.5 m to 1.5 m, preferably, the front preset distance is 1 m.

[0061] In some embodiments of the present invention, Figure 2 As shown, each air outlet 10 is provided with an air duct, and the air duct is connected to both the first air outlet and the second air outlet. The second air outlet blows out a breeze. According to the position of the user relative to the air induction interval 20, the air outlet direction, air volume and air outlet speed of the first air outlet and the second air outlet of at least one air outlet 10 are controlled, including a first air supply mode. The first air supply mode includes when the user is at the front side of the air induction interval 20, so that at least a part of the air flow blown out of each first air outlet flows to the oblique front of the first air outlet away from the other air outlet 10, forming a wide-angle wind guide. And the air volume of the air duct is the first preset air volume. When the user is on one side of the air induction interval 20, the corresponding first air outlet is closed so that the air flow of the air duct is blown out from the corresponding second air outlet and the air volume of the corresponding air duct is adjusted to the second preset air volume. The second preset air volume is less than the first preset air volume. The air outlet of the other air outlet 10 remains unchanged.

[0062] In these embodiments, the airflow blown out from the air duct is blown out through the first air outlet and the second air outlet. Controlling the air volume of the air duct can control the air volume of the first air outlet and the second air outlet. Of course, controlling the air volume of the first air outlet and the second air outlet can also control the air volume of the air duct accordingly. When the user is at the front side of the air induced interval 20, in order to avoid the airflow blown out by the air conditioner directly blowing on the user, the two first air outlets adjacent to the air induced interval 20 form a wide-angle wind guide, and at least a part of the airflow blown out of the two first air outlets is blown out to the two sides of the user respectively, thereby avoiding blowing directly to the user. At the same time, since the difference between the indoor ambient temperature and the set temperature is greater than the first preset difference, it means that the difference between the ambient temperature difference and the set temperature is relatively large. In order to adjust the ambient temperature difference as soon as possible, the first preset air volume is relatively large at this time. The airflow blown out from the air duct is blown out through the first air outlet and the second air outlet, and when one of the first air outlet and the second air outlet is closed, all the airflow blown out from the air duct is blown out from the other. When the user is at one side of the air induced interval 20, in order to prevent the air outlet of the air outlet 10 on the side corresponding to the user from blowing directly at the user, it is necessary to close the airflow blown obliquely forward from the first air outlet on the corresponding side. At this time, all the airflow blown out from the air duct of the corresponding air outlet 10 is blown out from the second air outlet, and the blown airflow is a breeze, which can avoid blowing directly at the user on one side of the air induced interval 20. At the same time, the air volume of the air duct corresponding to the user is correspondingly reduced to the second preset air volume. Moreover, in order to ensure that the ambient temperature difference can still be adjusted as soon as possible, the other air outlet 10 remains unchanged, that is, the air volume of the air duct of the other air outlet 10 is still the first preset air volume.

[0063] Furthermore, in some embodiments of the present invention, the first preset air volume is 750m 3 / h to 1000m 3 / h, preferably, the first preset air volume is 900m 3 / h. The second preset air volume is 300m 3 / h to 700m 3 / h, preferably, the second preset air volume is 500m 3 / h.

[0064] In some embodiments of the present invention, each air outlet 10 includes an air guide surface connected to the first air outlet, the air guide surface is located on the side of the first air outlet away from the other air outlet 10, and the air guide surface has a first edge and a second edge, and the second edge is located obliquely in front of the first edge away from the first air outlet. The air conditioner also includes an air guide device and an air outlet structure 18. The air guide device is arranged at the first air outlet, and is used to guide the outlet air in the width direction of the first air outlet and can be moved to a wide-angle air guide position defining a wide-angle air duct with the air guide surface. The air guide device includes at least one air guide plate 12. When the air guide device moves to the wide-angle air guide position, the edge of the air guide plate 12 closest to the air guide surface close to the air guide surface is located on the front side of the air guide surface, and a wide-angle air guide channel is defined between the air guide plate 12 located on the front side of the air guide surface and the air guide surface. The air outlet structure 18 is arranged at the second air outlet, and the air outlet structure 18 causes the airflow of the second air outlet to be dispersed.

[0065] In some embodiments of the present invention, at least a portion of the airflow blown out of each first air outlet is caused to flow obliquely in front of the first air outlet, away from the other air outlet portion 10, to form a wide-angle wind guide, including moving the air guide plate 12 closest to the air guide surface to a wide-angle wind guide position close to the edge of the air guide surface and on the front side of the air guide surface.

[0066] In some embodiments of the present invention, Figure 3 As shown, when the difference between the indoor ambient temperature and the set temperature is greater than the first preset difference, and there is no one within the preset distance in front of the air induced interval 20, the second air outlet mode is executed. The second air outlet mode is also called the ultra-fast cooling and heating mode. It includes making the air outlets of the two first air outlets face forward, and the air volume of the two air ducts is the third preset air volume. In other words, when there is a large difference between the indoor ambient temperature and the set temperature, and there is no one in front of the air conditioner, the air guide plate 12 moves to extend in the front-to-back direction, at which time the first air outlet is fully opened, and the air volume of the air duct is the third preset air volume, where the third preset air volume can be equal to the first preset air volume, and the air volume is larger.

[0067] Further, in some embodiments of the present invention, the third preset air volume is 750 3 / h to 1000m 3 / h, preferably, the third preset air volume is 900m 3 / h.

[0068] In some embodiments of the present invention, when the difference between the indoor ambient temperature and the set temperature is less than or equal to the first preset difference, the third air outlet mode is executed. The third air outlet mode is a comfortable air supply mode, which includes closing both first air outlets so that the air in the air duct is blown out from the corresponding second air outlet, and the air volume of the two air ducts is adjusted to a fourth preset air volume. The fourth preset air volume here is less than the first preset air volume and the third preset air volume, and greater than the second preset air volume.

[0069] Furthermore, in some embodiments of the present invention, the fourth preset air volume is 600m 3 / h to 800m 3 / h, preferably, the fourth preset air volume is 700m 3 / h.

[0070] In some embodiments of the present invention, the control method of the air conditioner further includes obtaining the average temperature of the indoor environment and the temperature fluctuation value at each point in the room. When the difference between the average temperature of the indoor environment and the set temperature is less than or equal to the second preset difference, and the temperature fluctuation value at each point in the room is less than the first preset fluctuation value, the temperature of the airflow at the preset distance in front of the first air outlet and the temperature fluctuation value at the first air outlet are obtained. When the temperature of the airflow at the preset distance in front of the first air outlet is less than or equal to the first preset value, and the temperature fluctuation value at the first air outlet is less than the second preset fluctuation value, or when the temperature of the airflow at the preset distance in front of the first air outlet is greater than or equal to the second preset value, and less than or equal to the first preset value, and the temperature fluctuation value at the first air outlet is less than the second preset fluctuation value, the fourth air supply mode is executed, and the fourth air supply mode includes closing both first air outlets so that the air outlet of the air outlet 10 is blown out from the corresponding second air outlet, and the air volume of the air duct is adjusted to the fifth preset air volume.

[0071] The average temperature of the indoor environment here refers to the average temperature of each detection point in the room at the same time. The temperature fluctuation value at the first air outlet refers to the standard deviation of the temperature of the first air outlet within the specified time. The larger the temperature fluctuation value, the more obvious the temperature at the first air outlet is. The temperature fluctuation value at each point in the room refers to the standard deviation of the temperature of each detection point in the room within the specified time. The larger the temperature fluctuation value, the more obvious the temperature of each monitoring point in the room is. When the average temperature of the indoor environment is near the set temperature, and the temperature fluctuations at the preset distance and the first air outlet are relatively stable, at this time, the fourth air outlet mode is executed, the air volume of the air duct is reduced to the fifth preset air volume, and all the airflow of the air duct is blown out from the second air outlet in the form of a breeze, and the air is soft. The fifth preset air volume here is less than the first preset air volume, the third preset air volume, the fourth preset air volume and the fifth preset air volume. This air outlet mode is a cool mode.

[0072] Further, in some embodiments of the present invention, the second preset difference is 1°C to 3°C, preferably, the second preset difference is 2°C. The first preset fluctuation value is 1°C to 2°C, preferably, the first preset fluctuation value is 1.5°C. The second preset fluctuation value is 0.5°C to 1.5°C, preferably, the second preset fluctuation value is 1°C. The fifth preset air volume is 300m 3 / h to 500m 3 / h, preferably, the fifth preset air volume is 400m 3 / h.

[0073] The ultimate goal of the above-mentioned air conditioner control method is to ensure that the temperature 1m in front of the air conditioner is not lower than 23°C and the wind speed is not greater than 1.5m / s, so that the air conditioner can achieve gentle air supply and make the user feel cool but not cold.

[0074] In some embodiments of the present invention, the fourth air supply mode further includes obtaining an index score of the indoor environment. At least according to the received user fresh air demand start instruction or at least according to the index score of the indoor environment, at least one air outlet 10 is controlled to blow out fresh air, and the airflow blown out by at least one air outlet 10 is blown out in a manner of all or part of the fresh air.

[0075] When the air conditioner completes the temperature adjustment work, fresh air can be started according to the user's wishes. The air conditioner can also be controlled to blow out fresh air according to the index score of the indoor environment. When the index score of the indoor environment shows that the indoor environment is not good, the air conditioner can be controlled to blow out fresh air. Of course, in some embodiments, the air conditioner can also be controlled to blow out healthy air, where healthy air is to add substances to the air outlet of the air conditioner or filter the air outlet of the air conditioner so that the air conditioner blows out healthy air that is good for human health.

[0076] Furthermore, in some embodiments of the present invention, the air conditioner further comprises an independent fresh air outlet, and the air conditioner blows out fresh air through the independent fresh air outlet. The first air outlet and the second air outlet are preferentially used to blow out fresh air, and when the fresh air volume of the new air is greater than the air volume of the first air outlet and the second air outlet, the independent fresh air outlet is used to blow out the remaining fresh air.

[0077] In some embodiments of the present invention, the index score of the indoor environment includes the index score of each component in the multiple components of the indoor air and the comprehensive index score. The comprehensive index score of the indoor environment is the average of multiple index scores of multiple components. For example, different carbon dioxide concentrations in the air correspond to different scores, and the lower the concentration, the higher the score. Different oxygen contents in the air correspond to different scores, and the closer the oxygen content is to .5% to .5%, the higher the score. Different PM2.5 in the air corresponds to different scores, and the smaller the value, the higher the score. The carbon dioxide concentration, oxygen content and PM2.5 in the air are measured, and then the corresponding index score values ​​are obtained by looking up the table or calculating, and the comprehensive index score of the indoor air is obtained according to the index score.

[0078] In some embodiments of the present invention, controlling the air conditioner to blow out fresh air according to the index score of the indoor environment includes causing the air conditioner to blow out fresh air when the comprehensive index score of the indoor environment is less than or equal to the first preset index score. Alternatively, causing the air conditioner to blow out fresh air when the index score of at least one component is less than or equal to the second preset index score. When the comprehensive index score of the indoor environment is less than or equal to the first preset index score, or when the index score of at least one component is less than or equal to the second preset index score, it indicates that the indoor environment at this time is not good, and it is necessary to control the air conditioner to blow out fresh air to improve the indoor environment. In some embodiments, the first preset index is 0.7 to 0.9, preferably, the first preset index is 0.8. The second preset index is 0.5 to 0.7, preferably, the second preset index is 0.6.

[0079] In some embodiments of the present invention, when the air conditioner blows out fresh air, the speed of the fresh air fan of the air conditioner for fresh air intake is controlled according to the indoor ambient temperature, the temperature fluctuation value at each point in the room, and the index score of the indoor environment, so as to control the input speed and output of the fresh air. The speed of the fresh air fan is determined by comprehensively considering the indoor ambient temperature, the temperature fluctuation value at each point in the room, and the index score of the indoor environment, so as to avoid large fluctuations in indoor temperature caused by the introduction of fresh air.

[0080] Further, in some embodiments of the present invention, Figure 4 As shown, the speed of the fresh air fan for fresh air intake of the air conditioner is controlled according to the indoor ambient temperature, the temperature fluctuation value at each point in the room and the index score of the indoor environment, including when the difference between the indoor ambient temperature and the set temperature is less than the third preset difference and the temperature fluctuation value at each point in the room is less than the second preset fluctuation value, the speed of the fresh air fan is set to the first speed. When the difference between the indoor ambient temperature and the set temperature is between the second preset difference and the third preset difference, and the temperature fluctuation value at each point in the room is less than the first preset fluctuation value, the speed of the fresh air fan is set to the second speed, and the second speed is lower than the first speed. The second preset difference is greater than the third preset difference. When the difference between the indoor ambient temperature and the set temperature is greater than the second preset difference, and the comprehensive index score of the indoor environment is less than or equal to the third preset index score, the speed of the fresh air fan is set to the third speed, and the third speed is lower than the second speed. When the difference between the indoor ambient temperature and the set temperature is greater than the second preset difference, and the comprehensive index score of the indoor environment is greater than the third preset index score, the fresh air fan is temporarily stopped until the difference between the indoor ambient temperature and the set temperature is less than or equal to the second preset difference or the index score of the indoor environment is less than or equal to the third preset index score.

[0081] The closer the indoor ambient temperature is to the set temperature, the faster the fresh air speed can be set. The smaller the temperature fluctuation at each point in the room, the faster the fresh air speed can be set.

[0082] Here, the third preset difference is 0.5° C. to 1.5° C., preferably, the third preset difference is 1° C. The third preset index score is 0.5 to 0.7, preferably, the third preset index score is 0.6.

[0083] In some embodiments of the present invention, the method for controlling an air conditioner further includes stopping the air conditioner from blowing out fresh air when each of the multiple components in the indoor air meets a preset requirement.

[0084] In some embodiments of the present invention, the preset requirement may be that the carbon dioxide concentration is lower than any value between 400ppm and 600ppm, preferably, the carbon dioxide concentration is lower than 500ppm. And / or PM2.5 is less than any value between 2 and 3, preferably, PM2.5 is less than 2.5. And / or the oxygen content in the indoor air is less than any value between 22% and 23%, preferably, the oxygen content in the indoor air is less than 23%, and the preset oxygen content is greater than any value between 19% and 21%, preferably, the oxygen content in the indoor air is greater than 20%.

[0085] In some embodiments of the present invention, Figure 5 As shown, the air conditioner further comprises a functional module part 40 disposed at the lower side of the two air outlet parts 10, and a fresh air inlet is provided on the functional module part 40. A fresh air fan 42 is disposed in the functional module part 40, and the fresh air fan 42 is configured to force fresh air into at least one air duct.
