[0030] Both first air outlets are closed so that the air from the air outlet is blown out from the corresponding second air outlet, and the air volume of the two air ducts is adjusted to the fifth preset air volume.

[0031] Optionally, the fourth air supply mode further includes:

[0046] In a control method for an air conditioner according to the present invention, when the air conditioner is operating, the airflow from each air outlet passes through a first air outlet and a second air outlet. When at least one of the two first air outlets blows forward airflow, it can drive the indoor air within the air intake interval to flow forward and mix together, thereby making the temperature of the mixed airflow closer to room temperature and making the mixed airflow gentler. By controlling the airflow direction, airflow volume, and airflow speed of the first and second air outlets of at least one air outlet, the air conditioner can prevent users at any position in front of the air intake interval from being directly blown by the airflow from the air conditioner, thereby improving the user experience and avoiding user discomfort.

[0057] Figure 1 This is a flowchart of a control method for an air conditioner according to an embodiment of the present invention, with reference to... Figures 2 to 5 In the air conditioner control method of this embodiment, the air conditioner includes two air outlets 10 arranged laterally. Each air outlet 10 has a first air outlet and a second air outlet extending along its length on its front side, with the first air outlet close to the other air outlet 10. The second air outlet 10 is spaced apart from the first air outlet 10 to form an air-guiding interval 20 between them. The air conditioner control method includes acquiring the indoor ambient temperature and whether there are people within a preset distance in front of the air-guiding interval 20. When the difference between the indoor ambient temperature and the set temperature is greater than a first preset difference, and there are people within the preset distance in front of the air-guiding interval 20, the position of the user relative to the air-guiding interval 20 is acquired. Based on the position of the user relative to the air-guiding interval 20, the air outlet direction, air volume, and air velocity of the first and second air outlets of at least one air outlet 10 are controlled.

[0058] When the air conditioner is operating, the airflow from each air outlet 10 passes through the first and second air outlets. When at least one of the two first air outlets blows forward airflow, it can drive the indoor air within the air intake interval 20 forward and mix them together, thereby making the temperature of the mixed airflow closer to room temperature and making the mixed airflow gentler. By controlling the airflow direction, airflow volume, and airflow speed of the first and second air outlets of at least one air outlet 10, the air conditioner can prevent users located at any position in front of the air intake interval 20 from being directly blown by the airflow from the air conditioner, thereby improving the user experience and avoiding user discomfort.

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

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

[0061] In some embodiments of the present invention, such as Figure 2 As shown, each air outlet 10 is equipped with an air duct, which is connected to both the first and second air outlets. The second air outlet blows out a gentle breeze. Based on the user's position relative to the air intake interval 20, the airflow direction, volume, and velocity of the first and second air outlets 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 in front of the air intake interval 20, causing at least a portion of the airflow from each first air outlet to flow diagonally forward and away from the other air outlet 10, forming a wide-angle airflow. The airflow volume in the air duct is a first preset airflow volume. When the user is on one side of the air intake interval 20, the corresponding first air outlet is closed, causing the airflow from the air duct to exit from the corresponding second air outlet, and the airflow volume in the corresponding air duct is adjusted to a second preset airflow volume. The second preset airflow volume is less than the first preset airflow volume. The airflow from the other air outlet 10 remains unchanged.

[0062] In these embodiments, the airflow from the duct passes through the first and second air outlets. Controlling the airflow in the duct controls the airflow at the first and second air outlets, and vice versa. When the user is in front of the air intake interval 20, to prevent the airflow from the air conditioner from blowing directly onto the user, the two first air outlets adjacent to the air intake interval 20 form a wide-angle air guide, with at least a portion of the airflow from the two first air outlets blowing towards the user's sides, thus avoiding direct airflow onto the user. Simultaneously, since the difference between the indoor ambient temperature and the set temperature is greater than a first preset difference, indicating a relatively large difference, the first preset airflow is relatively large to adjust the ambient temperature difference as quickly as possible. The airflow from the duct passes through the first and second air outlets, and when one of the first and second air outlets is closed, all the airflow from the duct exits through the other. When a user is on one side of the air intake interval 20, to prevent the air outlet 10 on the opposite side from blowing directly on the user, the airflow blowing diagonally forward from the first air outlet on the corresponding side needs to be closed. At this time, all the airflow blowing out of the duct of the corresponding air outlet 10 is blown out through the second air outlet, and the blown airflow is a gentle breeze, which can avoid blowing directly on the user on one side of the air intake interval 20. At the same time, the airflow of the duct corresponding to the user is correspondingly reduced to the second preset airflow. Moreover, in order to ensure that the ambient temperature difference can still be adjusted as quickly as possible, the other air outlet 10 remains unchanged, that is, the airflow of the duct of the other air outlet 10 is still the first preset airflow.

[0063] Furthermore, in some embodiments of the present invention, the first preset air volume is 750m³. 3 / h to 1000m 3 / h, preferably, the first preset air volume is 900m³ / h. 3 / h. The second preset airflow rate is 300m³ / h. 3 / h to 700m 3 / h, preferably, the second preset air volume is 500m³ / h. 3 / h.

[0064] In some embodiments of the present invention, each air outlet 10 includes an air guide surface connected to a first air outlet, the air guide surface being located on the side of the first air outlet away from another air outlet 10, the air guide surface having a first edge and a second edge, the second edge being 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 disposed at the first air outlet for guiding airflow in the width direction of the first air outlet and is movable to a wide-angle air guide position defining a wide-angle airflow channel with the air guide surface. The air guide device includes at least one air guide plate 12. When the air guide device is moved to the wide-angle air guide position, the edge of the air guide plate 12 closest to the air guide surface is located in front of the air guide surface, and a wide-angle air guide channel is defined between the air guide plate 12 in front of the air guide surface and the air guide surface. The air outlet structure 18 is disposed at the second air outlet, the air outlet structure 18 causing the airflow at the second air outlet to be dispersed.

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

[0066] In some embodiments of the present invention, such as 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 a preset distance in front of the air intake interval 20, the second air outlet mode is executed. The second air outlet mode is also called the rapid cooling / heating mode. This involves directing the airflow from both first air outlets forward, and setting the airflow in both ducts to a third preset airflow. In other words, when there is a significant difference between the indoor ambient temperature and the set temperature, and no one is in front of the air conditioner, the air guide plate 12 moves to extend in the front-to-back direction. At this time, the first air outlets are fully open, and the airflow in the ducts is the third preset airflow. Here, the third preset airflow can be equal to the first preset airflow, resulting in a larger airflow volume.

[0067] Furthermore, 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 900m³ / h. 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 a first preset difference, a third air supply mode is executed. The third air supply mode is a comfort air supply mode, which includes closing both first air outlets so that the airflow from the ducts exits from the corresponding second air outlets, and adjusting the airflow of both ducts to a fourth preset airflow. Here, the fourth preset airflow is less than the first and third preset airflows, but greater than the second preset airflow.

[0069] Furthermore, in some embodiments of the present invention, the fourth preset air volume is 600m³. 3 / h to 800m 3 / h, preferably, the fourth preset air volume is 700m³ / h. 3 / h.

[0070] In some embodiments of the present invention, the control method of the air conditioner further includes acquiring the average indoor ambient temperature and the temperature fluctuation value at various points in the room. When the difference between the average indoor ambient temperature and the set temperature is less than or equal to a second preset difference, and the temperature fluctuation value at various points in the room is less than a first preset fluctuation value, the temperature of the airflow at a preset distance in front of the first air outlet and the temperature fluctuation value at the first air outlet are acquired. 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, a fourth air supply mode is executed. The fourth air supply mode includes closing both first air outlets so that the air outlet 10 blows out from the corresponding second air outlet, and the airflow of the air duct is adjusted to a fifth preset airflow.

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

[0072] Further, in some embodiments of the present invention, the second preset difference value is 1°C to 3°C, preferably 2°C. The first preset fluctuation value is 1°C to 2°C, preferably 1.5°C. The second preset fluctuation value is 0.5°C to 1.5°C, preferably 1°C. The fifth preset air volume is 300m³ / h. 3 / h to 500m 3 / h, preferably, the fifth preset air volume is 400m³ / h. 3 / h.

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

[0074] In some embodiments of the present invention, the fourth air supply mode further includes acquiring an indoor environmental index score. At least one air outlet 10 is controlled to blow out fresh air based on at least a received user fresh air demand activation command or at least based on the indoor environmental index score, wherein the airflow blown out by the at least one air outlet 10 is either entirely or partially fresh air.

[0075] After the air conditioner completes its temperature adjustment, it can activate fresh air supply according to the user's preference. Alternatively, it can control the air conditioner to blow out fresh air based on indoor environmental quality indicators; for example, if the indoor environment score indicates poor conditions, 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. This healthy air is achieved by adding substances to or filtering the air outlet of the air conditioner to ensure that it blows out air that is beneficial to human health.

[0076] Furthermore, in some embodiments of the present invention, the air conditioner further includes an independent fresh air outlet, through which the air conditioner blows out fresh air. Fresh air is preferentially blown out from the first air outlet and the second air outlet; when the amount of fresh air is greater than the amount of air output from the first air outlet and the second air outlet, the remaining fresh air is blown out using the independent fresh air outlet.

[0077] In some embodiments of the present invention, the indoor environment index score includes an index score for each of the various components in the indoor air and a comprehensive index score. The comprehensive index score of the indoor environment is the average of the multiple index scores for the various components. For example, different concentrations of carbon dioxide in the air correspond to different scores, with lower concentrations resulting in higher scores; different oxygen contents in the air correspond to different scores, with oxygen contents closer to 0.5% to 0.5% resulting in higher scores; different PM2.5 concentrations in the air correspond to different scores, with lower values ​​resulting in higher scores. The carbon dioxide concentration, oxygen content, and PM2.5 in the air are measured, and the corresponding index score values ​​are obtained by looking up tables or calculating. The comprehensive index score of the indoor air is then obtained based on these index scores.

[0078] In some embodiments of the present invention, controlling the air conditioner to blow out fresh air based on the indoor environment index score 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 a 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 a 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 is poor 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 0.8. The second preset index is 0.5 to 0.7, preferably 0.6.

[0079] In some embodiments of the present invention, when the air conditioner blows out fresh air, the rotation speed of the fresh air fan used for fresh air intake is controlled based on the indoor ambient temperature, temperature fluctuation values ​​at various points in the room, and the indoor environmental index score, so as to control the input speed and output volume of fresh air. The fresh air fan speed is determined by comprehensively considering the indoor ambient temperature, temperature fluctuation values ​​at various points in the room, and the indoor environmental index score, thus avoiding large fluctuations in indoor temperature caused by the introduction of fresh air.

[0080] Furthermore, in some embodiments of the present invention, such as Figure 4 As shown, the speed of the fresh air intake fan in the air conditioner is controlled based on the indoor ambient temperature, temperature fluctuation values ​​at various points indoors, and the indoor environment index score. Specifically, when the difference between the indoor ambient temperature and the set temperature is less than a third preset difference and the temperature fluctuation values ​​at various points indoors are less than a second preset fluctuation value, the fresh air intake fan speed is set to the first speed. When the difference between the indoor ambient temperature and the set temperature is between the second and third preset differences, and the temperature fluctuation values ​​at various points indoors are less than the first preset fluctuation value, the fresh air intake fan speed is set to the second speed, which 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, which 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 higher the fresh air velocity can be set. The smaller the temperature fluctuation at various points indoors, the higher the fresh air velocity can be set.

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

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

[0084] In some embodiments of the present invention, the preset requirements can be a carbon dioxide concentration of less than 400 ppm to 600 ppm, preferably less than 500 ppm. And / or PM2.5 less than 2 to 3, preferably less than 2.5. And / or indoor air oxygen content less than 22% to 23%, preferably less than 23%, and a preset oxygen content greater than 19% to 21%, preferably greater than 20%.
