[0002] Air conditioners are a widely used appliance in people's lives. They regulate indoor temperature to provide users with a healthy and comfortable indoor environment. Air conditioners include wall-mounted air conditioners, window air conditioners, and floor-standing air conditioners, etc.

[0003] Air conditioner cabinet units adjust the air outlet direction through louvers to deliver air to different areas of the room under different heat exchange functions. However, the air conditioner cabinet units in related technologies have limited air supply range in the vertical direction, and the air supply and heat exchange mode of air conditioner cabinet units is single, which cannot meet the needs of different scenarios and has room for improvement.

[0049] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0050] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0051] The control method of an air conditioner according to a first aspect of the present invention will now be described with reference to the accompanying drawings.

[0052] The control method of an air conditioner according to an embodiment of the present invention, such as Figure 3 As shown, the air conditioner 100 includes a front panel 11, a first air outlet 1a disposed above the front panel 11, a second air outlet 1b disposed below the front panel 11, and a third air outlet 1c disposed on the left and right sides of the front panel 11. The air conditioner 100 has air ducts that are respectively connected to the first air outlet 1a, the second air outlet 1b and the third air outlet 1c.

[0053] The first air outlet 1a, the third air outlet 1c, and the second air outlet 1b are arranged sequentially in the vertical direction, which can increase the air supply range of the air conditioner 100 in the vertical direction, improve the air supply effect, and improve the heat exchange efficiency of the air conditioner 100. For example, the first air outlet 1a is positioned higher than the third air outlet 1c, and the second air outlet 1b is positioned lower than the first air outlet. The first air outlet 1a and the second air outlet 1b are not directly facing the user's body, thus reducing the feeling of direct airflow. There are two third air outlets 1c, located on the left and right sides of the front panel 11, which can increase the air supply range of the air conditioner 100 in the horizontal direction and improve the air supply effect.

[0054] The air conditioner 100 has an air duct. The air supplied by the air conditioner 100 flows through the air duct and then flows out from the air outlet. The air duct is connected to the first air outlet 1a, the second air outlet 1b and the third air outlet 1c respectively. Therefore, the first air outlet 1a, the second air outlet 1b and the third air outlet 1c can all discharge air.

[0055] like Figure 1 and Figure 2 As shown, the control method for the air conditioner includes the following steps: determining to enter a first mode, and controlling the air outlet states of the first air outlet 1a and the third air outlet 1c according to the difference between the indoor temperature and the first preset temperature; determining to enter a second mode, and controlling the air outlet states of the second air outlet 1b and the third air outlet 1c according to the difference between the indoor temperature and the second preset temperature. The air outlet state may include whether air is being emitted and the air outlet angle, etc.

[0056] Optionally, the first preset temperature can be a temperature value automatically and intelligently set by the control system of the air conditioner 100. When entering the first mode, the air conditioner 100 only needs to detect the indoor temperature, and then controls the airflow status of the first air outlet 1a and the third air outlet 1c based on the difference between the indoor temperature and the first preset temperature. Similarly, the second preset temperature can also be a temperature automatically and intelligently set by the control system of the air conditioner 100. Alternatively, the first preset temperature can also be a temperature value manually input by the user. When entering the first mode, the air conditioner 100 needs to detect the indoor temperature and receive the first preset temperature, and then control the airflow status of the first air outlet 1a and the third air outlet 1c based on the difference between the indoor temperature and the first preset temperature. Similarly, the second preset temperature can also be a temperature value manually input by the user.

[0057] It is worth noting the airflow status of the first air outlet 1a and the third air outlet 1c, as well as the airflow status of the second air outlet 1b and the third air outlet 1c, including whether air is being emitted and the airflow angle.

[0058] For example, in the first mode, the air outlets 1a and 1c are controlled according to the difference between the indoor temperature and the first preset temperature to control the air supply effect of the air conditioner 100 at a relatively high position; in the second mode, the air outlets 1b and 1c are controlled according to the difference between the indoor temperature and the second preset temperature to control the air supply effect of the air conditioner 100 at a relatively low position. Thus, the air conditioner 100 can be controlled to achieve multi-mode air supply, thereby meeting the needs of different scenarios and improving the functionality of the air conditioner 100.

[0059] For example, the first mode is a cooling mode, which controls the first air outlet 1a and the third air outlet 1c to emit cold air, thereby increasing the overall air outlet height of the cold air and improving the situation where the cold air blows directly onto the human body. The cold air naturally sinks from top to bottom, improving the cooling effect. For example, the second mode is a heating mode, which controls the second air outlet 1b and the third air outlet 1c to emit hot air, thereby reducing the overall air outlet height of the hot air. For example, the hot air can be delivered to the feet first to warm the feet, improving the situation where the head is hot and the feet are cold, and improving the steady-state thermal comfort of the human body.

[0060] For example, in the first mode, which is the cooling mode, when the difference between the indoor temperature and the first preset temperature is small, it indicates that cooling is not the most urgent function. In this case, the first air outlet 1a can be controlled to blow air out, and the third air outlet 1c can be controlled to blow air upward to reduce the direct airflow. The airflow of the third air outlet 1c can be reduced, thereby increasing the airflow of the first air outlet 1a by reducing the airflow of the third air outlet 1c, so as to improve the effect of cold air blowing directly towards the user. Alternatively, when the difference between the indoor temperature and the first preset temperature is large, it indicates that cooling is the most urgent function. In this case, the third air outlet 1c can be controlled to blow air directly to maximize the airflow.

[0061] For example, in the second mode, which is the cooling mode, when the difference between the indoor temperature and the second preset temperature is small, it indicates that the hot air heating is not the most urgent function. In this case, the second air outlet 1b can be controlled to blow air downwards to reduce the direct airflow and the airflow volume of the third air outlet 1c can be reduced. This reduces the airflow volume of the third air outlet 1c and increases the airflow volume of the second air outlet 1b, thereby improving the effect of hot air blowing directly towards the user, which is beneficial for warming the feet. Alternatively, when the difference between the indoor temperature and the second preset temperature is large, it indicates that the hot air heating is the most urgent function. In this case, the third air outlet 1c can be controlled to blow air directly to maximize the airflow volume.

[0062] According to the air conditioner control method of the present invention, by controlling the airflow to be delivered from a first air outlet 1a higher than the third air outlet 1c and from a second air outlet 1b lower than the third air outlet 1c, the vertical air supply range of the air conditioner 100 can be increased, and the air supply effect of the air conditioner 100 can be improved, compared to only delivering airflow from the third air outlet. Furthermore, in different modes, by controlling the air outlet states of different outlets according to the difference between the indoor temperature and the preset temperature, the air conditioner 100 can be controlled to achieve multi-mode air supply and heat exchange, thereby meeting the needs of different scenarios.

[0063] In some embodiments of the present invention, such as Figure 1As shown, after determining to enter the first mode, and before controlling the air outlet state of the first air outlet 1a and the third air outlet 1c according to the difference between the indoor temperature and the first preset temperature, the steps include: controlling the third air outlet 1c to supply air horizontally, or supply air within an angle range of less than 15° relative to the horizontal.

[0064] Once the first mode is entered, the airflow status of the first air outlet 1a and the third air outlet 1c will be controlled. Before controlling the airflow status of the first air outlet 1a and the third air outlet 1c, the third air outlet 1c will be controlled to supply air horizontally, or within an angle of less than 15° relative to the horizontal, to prepare for the next change in airflow status. When the airflow angle of the first air outlet 1a and / or the third air outlet 1c is changed, the air conditioner 100, which supplies air horizontally or within an angle of less than 15° relative to the horizontal, can respond quickly, improving operating efficiency.

[0065] In some embodiments of the present invention, such as Figure 1 As shown, the air outlet states of the first air outlet 1a and the third air outlet 1c are controlled according to the difference between the indoor temperature and the first preset temperature, including the following steps: obtaining the indoor temperature; determining the difference between the indoor temperature and the first preset temperature as the first temperature difference; and adjusting the air outlet angle of the third air outlet 1c in the vertical direction according to the range of the first temperature difference.

[0066] It is worth noting that the air conditioner 100 delivers air horizontally along the third air outlet 1c or at a slight vertical angle, which is the air delivery mode with the maximum air volume of the air conditioner 100. Increasing the upward air outlet angle of the third air outlet 1c will increase the vertical air delivery height, but will also correspondingly reduce the air volume delivered by the third air outlet 1c.

[0067] The control method in some embodiments of the present invention adjusts the air outlet angle of the third air outlet 1c in the vertical direction according to the difference between the indoor temperature and the first preset temperature. This can improve the air supply height of the air conditioner 100 in the vertical direction while ensuring the heat exchange efficiency of the air conditioner 100, thereby improving the air supply effect of the air conditioner 100.

[0068] It's also worth noting that when the first mode is activated, the first air outlet 1a will continuously emit air. Adjusting the vertical air outlet angle of the third air outlet 1c will also affect the airflow from the first air outlet 1a. Increasing the upward air outlet angle of the third air outlet 1c will reduce the direct airflow from the third air outlet 1c and increase the airflow from the first air outlet 1a.

[0069] By adding a first air outlet 1a above the third air outlet 1c, the air volume loss of the air conditioner 100 can be reduced when adjusting the air outlet angle of the third air outlet 1c in the vertical direction, thus ensuring the air heat exchange effect of the air conditioner 100.

[0070] In some embodiments of the present invention, such as Figure 1 As shown, adjusting the air outlet angle of the third air outlet 1c in the vertical direction according to the range of the first temperature difference includes the following steps:

[0071] Once the first temperature difference is determined to be higher than the first temperature threshold, the third air outlet 1c is controlled to deliver air at a relatively horizontal upward tilt of the first angle.

[0072] If the first temperature difference is determined to be lower than the first temperature threshold and higher than the second temperature threshold, the third air outlet 1c is controlled to deliver air at a relatively horizontally upward tilted second angle, where the second angle is greater than the first angle.

[0073] If the first temperature difference is determined to be lower than the second temperature threshold, the third air outlet 1c is controlled to deliver air at a relatively horizontal upward tilt at a third angle, which is greater than the second angle.

[0074] If the first temperature difference is higher than the first temperature threshold, it means that the difference between the indoor temperature and the first preset temperature is large. The main function of the air conditioner 100 is to quickly exchange heat to reach the first preset temperature. Therefore, the third air outlet 1c is controlled to supply air at a relatively horizontal upward tilt at a small first angle to prioritize air supply and improve heat exchange efficiency.

[0075] If the first temperature difference is lower than the first temperature threshold and higher than the second temperature threshold, it means that the difference between the indoor temperature and the first preset temperature is in the middle. The function of the air conditioner 100 is to exchange heat and improve the comfort of air supply. Therefore, the third air outlet 1c is controlled to supply air at a relatively horizontal and upward tilted second angle, which ensures the air supply volume and reduces the feeling of direct airflow.

[0076] If the first temperature difference is lower than the second temperature threshold, it means that the difference between the indoor temperature and the first preset temperature is small. The main function of the air conditioner 100 is to reduce the feeling of direct airflow and improve the uniformity of indoor temperature. Therefore, the third air outlet 1c is controlled to deliver air at a relatively large upward tilt angle, passing over the user's body, reducing the feeling of direct airflow, increasing the air delivery distance, accelerating the circulation of air in the room, reducing the temperature difference in various places, and improving the heat exchange effect.

[0077] Optionally, the first angle can be 15°, 18°, 20°, 25°, 30°, etc.

[0078] Optionally, the second angle can be 35°, 40°, 42°, 45°, 50°, etc.

[0079] Optionally, the third angle can be 55°, 60°, 64°, 65°, 70°, 75°, etc.

[0080] Optionally, when the first temperature difference equals the first temperature threshold, the third air outlet 1c can be controlled to supply air at a relatively horizontal upward tilting first angle; or, alternatively, when the first temperature difference equals the first temperature threshold, the third air outlet 1c can be controlled to supply air at a relatively horizontal upward tilting second angle.

[0081] Optionally, when the first temperature difference equals the second temperature threshold, the third air outlet 1c can be controlled to supply air at a second angle that is relatively horizontally upward; or, alternatively, when the first temperature difference equals the second temperature threshold, the third air outlet 1c can be controlled to supply air at a third angle that is relatively horizontally upward.

[0082] In some specific embodiments of the present invention, such as Figure 4 As shown, the first mode is the cooling mode. In the first mode, as... Figure 5 and Figure 6 As shown in the attached diagram, the dashed arrows indicate the airflow direction. The first air outlet 1a and the third air outlet 1c emit cold air, which is then directed downwards to allow the cold air to settle naturally, thus improving the cooling effect. The first temperature threshold is 3℃, the second temperature threshold is 1℃, the first angle is 15°, the second angle is 35°, and the third angle is 55°.

[0083] If the first temperature difference is determined to be higher than 3℃, the third air outlet 1c is controlled to supply air at a relative horizontal upward tilt of 15°. The upward air supply angle of the third air outlet 1c is relatively small, and the air volume of the third air outlet 1c is relatively large. The air volume of the first air outlet 1a is relatively small. The air conditioner 100 outputs cold air with a larger air volume, thereby improving the cooling efficiency.

[0084] If the first temperature difference is determined to be below 3℃ and above 1℃, the third air outlet 1c is controlled to supply air at a relative horizontal upward tilt of 35°. As the upward air supply angle of the third air outlet 1c increases, the air volume of the third air outlet 1c decreases, and the air volume of the first air outlet 1a increases. The air conditioner 100 delivers cool air with a lower air volume and a cooler feel, thereby reducing the feeling of direct airflow while cooling the air.

[0085] Once the first temperature difference is determined to be below 1℃, the third air outlet 1c is controlled to supply air at a relative horizontal upward tilt of 55°. The upward air supply angle of the third air outlet 1c is relatively large, and the air volume of the third air outlet 1c is relatively small. The air volume of the first air outlet 1a continues to increase. The air conditioner 100 supplies air upward to reduce the feeling of direct airflow and increase the delivery range of cold air, accelerate the circulation of air in the room, reduce the indoor temperature difference, and allow the cold air to naturally sink from top to bottom, thereby improving the cooling effect.

[0086] In some embodiments of the present invention, such as Figure 7 and Figure 8As shown, the air conditioner 100 includes an air guiding unit 21 for adjusting the vertical air guiding angle of the third air outlet 1c. The air guiding unit 21 includes an air guiding assembly 211 and a driving assembly 212 for driving the air guiding assembly 211, as shown in the figure. Figure 9 and Figure 10 As shown, the drive assembly 212 includes a motor 2121, a gear 2122, and a rack 2123. The motor 2121 is a stepper motor and is connected to the gear 2122. The gear 2122 meshes with the rack 2123. The motor 2121 is a power component. The motor 2121 drives the gear 2122 to rotate. The gear 2122 meshes with the rack 2123, and the rack 2123 moves vertically under the meshing action with the gear 2122.

[0087] As the driving source, the stepper motor's step angle determines its rotation amplitude. The number of steps required for the stepper motor rotor to rotate one revolution is:

[0088] n0=360 / θ (1)

[0089] Where n0 is the number of steps required for the stepper motor rotor to rotate one revolution, and θ is the step angle of the stepper motor.

[0090] The motion is transmitted from the stepper motor to gear 2122. The number of teeth and module of gear 2122 are basic specifications, from which the pitch circle diameter of gear 2122 can be calculated.

[0091] d=mz (2)

[0092] Where d is the pitch circle diameter of gear 2122, m is the number of teeth of gear 2122, and z is the module of gear 2122.

[0093] Furthermore, the motion of gear 2122 is converted into the up-and-down motion of rack 2123:

[0094] L=n / n0×π×d=nθ / 360×π×mz (3)

[0095] Where n is the actual number of steps the stepper motor takes.

[0096] In summary, the movement distance of the rack 2123 in the vertical direction can be controlled by controlling the number of rotation steps of the stepper motor, which in turn can drive the air guide unit 21 to adjust the vertical air guide angle of the third air outlet 1c.

[0097] Controlling the third air outlet 1c to deliver air at a relatively horizontal upward tilting first angle includes the following steps: controlling the stepper motor to rotate a first preset number of steps, causing the rack 2123 to move upward a first preset distance.

[0098] Controlling the third air outlet 1c to deliver air at a relatively horizontally upward tilted second angle includes the following steps: controlling the stepper motor to rotate a second preset number of steps, causing the rack 2123 to move upward a second preset distance, wherein the second preset number of steps is greater than the first preset number of steps, and the second preset distance is greater than the first preset distance.

[0099] Controlling the third air outlet 1c to deliver air at a relatively horizontal upward tilt at a third angle includes the following steps: controlling the stepper motor to rotate a third preset number of steps, causing the rack 2123 to move upward a third preset distance, wherein the third preset number of steps is greater than the second preset number of steps, and the third preset distance is greater than the second preset distance.

[0100] In some specific embodiments of the present invention, the step angle of the stepper motor is 3°, the gear 2122 is 20, and the module of the gear 2122 is 1.5mm.

[0101] Controlling the third air outlet 1c to deliver air at a relatively horizontal upward tilting first angle includes the following steps: controlling the stepper motor to rotate 18 steps, causing the rack 2123 to move upward by 10mm.

[0102] Controlling the third air outlet 1c to supply air at a relatively horizontal upward tilting second angle includes the following steps: controlling the stepper motor to rotate 54 steps, causing the rack 2123 to move upward by 30mm.

[0103] Controlling the third air outlet 1c to deliver air at a relatively horizontal upward tilt at a third angle includes the following steps: controlling the stepper motor to rotate 90 steps, causing the rack 2123 to move upward by 50mm.

[0104] In some embodiments of the present invention, such as Figure 2 As shown, after determining to enter the second mode, and before controlling the air outlet state of the second air outlet 1b and the third air outlet 1c according to the difference between the indoor temperature and the second preset temperature, the steps include: controlling the third air outlet 1c to supply air horizontally, or supply air within an angle range of less than 15° relative to the horizontal.

[0105] Once the second mode is confirmed, the airflow status of the second air outlet 1b and the third air outlet 1c will be controlled. Before controlling the airflow status of the second air outlet 1b and the third air outlet 1c, the third air outlet 1c will be controlled to supply air horizontally, or within an angle of less than 15° relative to the horizontal. This prepares for the next step of changing the airflow status. When the airflow angle of the second air outlet 1b and / or the third air outlet 1c is changed, the air conditioner 100, which supplies air horizontally or within an angle of less than 15° relative to the horizontal, can respond quickly, improving operating efficiency.

[0106] In some embodiments of the present invention, such as Figure 2As shown, the air outlet states of the second air outlet 1b and the third air outlet 1c are controlled according to the difference between the indoor temperature and the second preset temperature, including the following steps: acquiring the indoor temperature; determining the difference between the indoor temperature and the second preset temperature as the second temperature difference; and adjusting the air outlet angle of the third air outlet 1c in the vertical direction according to the range of the second temperature difference.

[0107] It is worth noting that the air conditioner 100 delivers air horizontally along the third air outlet 1c or at a small vertical angle, which is the air delivery mode with the maximum air volume of the air conditioner 100. Increasing the downward air outlet angle of the third air outlet 1c will increase the vertical air delivery height, but will also correspondingly reduce the air volume delivered by the third air outlet 1c.

[0108] The control method in some embodiments of the present invention adjusts the air outlet angle of the third air outlet 1c in the vertical direction according to the difference between the indoor temperature and the second preset temperature. This can improve the air supply height of the air conditioner 100 in the vertical direction while ensuring the heat exchange efficiency of the air conditioner 100, thereby improving the air supply effect of the air conditioner 100.

[0109] It's also worth noting that when the second mode is activated, the second air outlet 1b continuously emits air, and adjusting the vertical air outlet angle of the third air outlet 1c will also affect the airflow from the second air outlet 1b. Increasing the downward air outlet angle of the third air outlet 1c will reduce the direct airflow from the third air outlet 1c and increase the airflow from the second air outlet 1b.

[0110] By adding a second air outlet 1b below the third air outlet 1c, the air volume loss of the air conditioner 100 can be reduced when adjusting the air outlet angle of the third air outlet 1c in the vertical direction, thus ensuring the air heat exchange effect of the air conditioner 100.

[0111] In some embodiments of the present invention, such as Figure 2 As shown, adjusting the air outlet angle of the third air outlet 1c in the vertical direction according to the range of the second temperature difference includes the following steps:

[0112] If the second temperature difference is determined to be higher than the third temperature threshold, control the third air outlet 1c to deliver air at a fourth angle that is relatively horizontally upward.

[0113] If the second temperature difference is determined to be lower than the third temperature threshold and higher than the fourth temperature threshold, the third air outlet 1c is controlled to deliver air at a fifth angle that is relatively horizontally upward, and the fifth angle is greater than the fourth angle.

[0114] If the second temperature difference is determined to be lower than the fourth temperature threshold, the third air outlet 1c is controlled to supply air at a relatively horizontal upward tilt at a sixth angle, which is greater than the fifth angle.

[0115] The second temperature difference is higher than the third temperature threshold, indicating that the difference between the indoor temperature and the second preset temperature is large. The main function of the air conditioner 100 is to quickly exchange heat to reach the second preset temperature. Therefore, the third air outlet 1c is controlled to supply air at a relatively horizontal downward tilt at a smaller fourth angle to prioritize air supply and improve heat exchange efficiency.

[0116] The second temperature difference is lower than the third temperature threshold but higher than the fourth temperature threshold, indicating that the difference between the indoor temperature and the second preset temperature is in the middle. The function of the air conditioner 100 is to exchange heat and improve the comfort of air supply. Therefore, the third air outlet 1c is controlled to supply air at a relatively horizontal and downward tilted fifth angle, which ensures the air supply volume and reduces the feeling of direct airflow.

[0117] The second temperature difference is lower than the fourth temperature threshold, indicating that the difference between the indoor temperature and the second preset temperature is small. The main function of the air conditioner 100 is to reduce the feeling of direct airflow and improve the uniformity of indoor temperature. Therefore, the third air outlet 1c is controlled to deliver air at a relatively horizontal downward tilt at a sixth angle, passing over the user's body and reducing the feeling of direct airflow.

[0118] Optionally, the fourth angle can be 15°, 20°, 22°, 25°, 30°, 33°, etc.

[0119] Optionally, the fifth angle can be 35°, 38°, 40°, 45°, 50°, 54°, etc.

[0120] Optionally, the sixth angle can be 55°, 60°, 65°, 66°, 70°, 75°, etc.

[0121] Optionally, when the second temperature difference equals the third temperature threshold, the third air outlet 1c can be controlled to supply air at a fourth angle that is relatively horizontally downward; or, alternatively, when the second temperature difference equals the third temperature threshold, the third air outlet 1c can be controlled to supply air at a fifth angle that is relatively horizontally downward.

[0122] Optionally, when the second temperature difference equals the fourth temperature threshold, the third air outlet 1c can be controlled to supply air at a fifth angle that is relatively horizontally downward; or, alternatively, when the second temperature difference equals the fourth temperature threshold, the third air outlet 1c can be controlled to supply air at a sixth angle that is relatively horizontally downward.

[0123] In some specific embodiments of the present invention, such as Figure 11 As shown, the second mode is the heating mode. In the second mode, as... Figure 12 and Figure 13As shown in the attached diagram, the dashed arrows indicate the airflow direction. Hot air is emitted from the second air outlet 1b and the third air outlet 1c, directed from below. The hot air first reaches the feet, warming them and alleviating the problem of a hot head and cold feet, thus improving the body's steady-state thermal comfort. The third temperature threshold is 3℃, the fourth temperature threshold is 1℃, the fourth angle is 15°, the fifth angle is 35°, and the sixth angle is 55°.

[0124] If the second temperature difference is determined to be higher than 3℃, the third air outlet 1c is controlled to supply air at a relative horizontal downward tilt of 15°. The downward air supply angle of the third air outlet 1c is small, and the air volume of the third air outlet 1c is large. The air volume of the second air outlet 1b is small. The air conditioner 100 outputs hot air with a large air volume, thereby improving the heating efficiency.

[0125] If the second temperature difference is determined to be below 3℃ and above 1℃, the third air outlet 1c is controlled to supply air at a relative horizontal downward tilt of 35°. As the downward air supply angle of the third air outlet 1c increases, the air volume of the third air outlet 1c decreases, and the air volume of the second air outlet 1b increases. The air conditioner 100 delivers hot air with a lower air volume and a lower wind feel, reducing the direct airflow feel while raising the temperature.

[0126] Once the first temperature difference is determined to be below 1℃, the third air outlet 1c is controlled to supply air at a relative horizontal downward tilt of 55°. The downward air supply angle of the third air outlet 1c is relatively large, and the air volume of the third air outlet 1c is relatively small. The air volume of the second air outlet 1b continues to increase, and the air conditioner 100 supplies air downward to reduce the feeling of direct airflow and improve human comfort.

[0127] In some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the air conditioner 100 includes an air guiding unit 21 for adjusting the vertical air guiding angle of the third air outlet 1c. The air guiding unit 21 includes an air guiding assembly 211 and a driving assembly 212 for driving the air guiding assembly 211, as shown in the figure. Figure 9 and Figure 10 As shown, the drive assembly 212 includes a motor 2121, a gear 2122, and a rack 2123. The motor 2121 is a stepper motor and is connected to the gear 2122. The gear 2122 meshes with the rack 2123. The motor 2121 is a power component. The motor 2121 drives the gear 2122 to rotate. The gear 2122 meshes with the rack 2123, and the rack 2123 moves vertically under the meshing action with the gear 2122.

[0128] As the driving source, the stepper motor's step angle determines its rotation amplitude. The number of steps required for the stepper motor rotor to rotate one revolution is:

[0129] n0=360 / θ (1)

[0130] Where n0 is the number of steps required for the stepper motor rotor to rotate one revolution, and θ is the step angle of the stepper motor.

[0131] The motion is transmitted from the stepper motor to gear 2122. The number of teeth and module of gear 2122 are basic specifications, from which the pitch circle diameter of gear 2122 can be calculated.

[0132] d=mz (2)

[0133] Where d is the pitch circle diameter of gear 2122, m is the number of teeth of gear 2122, and z is the module of gear 2122.

[0134] Furthermore, the motion of gear 2122 is converted into the up-and-down motion of rack 2123:

[0135] L=n / n0×π×d=nθ / 360×π×mz (3)

[0136] Where n is the actual number of steps the stepper motor takes.

[0137] In summary, the movement distance of the rack 2123 in the vertical direction can be controlled by controlling the number of rotation steps of the stepper motor, which in turn can drive the air guide unit 21 to adjust the vertical air guide angle of the third air outlet 1c.

[0138] Controlling the third air outlet 1c to deliver air at a relatively horizontal downward tilting fourth angle includes the following steps: controlling the stepper motor to rotate a fourth preset number of steps, causing the rack 2123 to move downward a fourth preset distance.

[0139] Controlling the third air outlet 1c to deliver air at a relatively horizontal downward tilt of a fifth angle includes the following steps: controlling the stepper motor to rotate a fifth preset number of steps, causing the rack 2123 to move downward a fifth preset distance, wherein the fifth preset number of steps is greater than the fourth preset number of steps, and the fifth preset distance is greater than the fourth preset distance.

[0140] Controlling the third air outlet 1c to deliver air at a relatively horizontal downward tilt of a sixth angle includes the following steps: controlling the stepper motor to rotate a sixth preset number of steps, causing the rack 2123 to move upward a sixth preset distance, wherein the sixth preset number of steps is greater than the fifth preset number of steps, and the sixth preset distance is greater than the fifth preset distance.

[0141] In some specific embodiments of the present invention, the step angle of the stepper motor is 3°, the gear 2122 is 20, and the module of the gear 2122 is 1.5mm.

[0142] Controlling the third air outlet 1c to deliver air at a relatively horizontal downward tilt at a fourth angle includes the following steps: controlling the stepper motor to rotate 18 steps, causing the rack 2123 to move downward by 10mm.

[0143] Controlling the third air outlet 1c to deliver air at a relatively horizontal downward tilt of the fifth angle includes the following steps: controlling the stepper motor to rotate 54 steps, causing the rack 2123 to move downward by 30mm.

[0144] Controlling the third air outlet 1c to deliver air at a relatively horizontal downward tilt of the sixth angle includes the following steps: controlling the stepper motor to rotate 90 steps, causing the rack 2123 to move downward by 50mm.

[0145] An air conditioner 100 according to a second aspect of the present invention will now be described with reference to the accompanying drawings.

[0146] An air conditioner 100 according to an embodiment of the present invention applies the control method of the first aspect of the present invention. For example... Figure 3 and Figure 14 As shown, the air conditioner 100 includes: an air conditioner body 1 and an air guide component 2. The air conditioner body 1 includes a front panel 11 and an air outlet component 12. The front panel 11 extends vertically along its length and is located in front of the air outlet component 12. The air conditioner body 1 has a first air outlet 1a located above the front panel 11, a second air outlet 1b located below the front panel 11, and third air outlets 1c located on the left and right sides of the front panel 11. Figure 7 and Figure 14 As shown, the air outlet component 12 includes a first air duct 12a connected to the first air outlet 1a, a second air duct 12b connected to the second air outlet 1b, and a third air duct 12c connected to the first air duct 12a and the second air duct 12b respectively. The third air duct 12c includes two air outlet sections 12c1 on the left and right sides respectively connected to the third air outlets 1c on the left and right sides. The air conditioner body 1 is configured to switch whether the first air outlet 1a and the second air outlet 1b are emitting air.

[0147] The air outlet component 12 has an air duct, through which the air supplied by the air conditioner 100 flows and then exits from the air outlet. The airflow is delivered from the first air outlet 1a via the first air duct 12a, from the second air outlet 1b via the second air duct 12b, and from the third air outlet 1c via the third air duct 12c. The third air duct 12c is connected to both the first air duct 12a and the second air duct 12b. Therefore, optionally, the air supplied by the air conditioner 100 can be delivered to one or both of the third air duct 12c, the first air duct 12a, and the second air duct 12b, and then flow to the corresponding air outlet through the connection of the air ducts. For example, the air conditioner 100 supplies air to the third air duct 12c, which is connected to the first air duct 12a and the second air duct 12b. The airflow flows through the third air duct 12c to the first air duct 12a, i.e., from the first air outlet 1a; the airflow flows through the third air duct 12c to the second air duct 12b, i.e., from the second air outlet 1b; and the airflow flows directly through the third air duct 12c to the third air outlet 1c, i.e., from the third air outlet 1c. Alternatively, the air conditioner 100 supplies air to the first air duct 12a, the second air duct 12b, and the third air duct 12c. The first air outlet 1a, the second air outlet 1b, and the third air outlet 1c can supply air independently or in conjunction with each other.

[0148] Both the first air outlet 1a and the second air outlet 1b can be selectively opened and closed. On the one hand, they can be adjusted to match the air outlet mode of the air conditioner 100 to improve the air supply effect of the air conditioner 100. On the other hand, they can block external pollutants outside the air conditioner 100 and improve the cleanliness of the air conditioner 100.

[0149] like Figure 7 and Figure 8 As shown, the air guide component 2 is used to guide the airflow within the air duct to improve the air output effect of the air conditioner 100. The air guide component 2 includes two air guide units 21, which are respectively arranged with two air outlet sections 12c1. The air guide unit 21 includes an air guide assembly 211 and a drive assembly 212. The air guide assembly 211 is located within the air outlet section 12c1 and includes a plurality of air guide vanes 2111 spaced apart in the vertical direction. The drive assembly 212 is connected to the air guide assembly 211 to drive the air guide vanes 2111 to adjust the vertical air guide angle.

[0150] The air guiding component 2 includes two air guiding units 21, which are respectively disposed corresponding to two air outlet sections 12c1. Optionally, the two air guiding units 21 can work independently, with each unit guiding the airflow in the two air outlet sections 12c1 independently; alternatively, the two air guiding units 21 can work in conjunction with each other, guiding the airflow in the two air outlet sections 12c1 simultaneously. Both of these options fall within the protection scope of this invention. By providing air guiding units 21 in the two air outlet sections 12c1 respectively, different air outlet effects can be achieved, increasing the air outlet modes of the air conditioner 100.

[0151] The air guiding unit 21 includes an air guiding component 211 and a drive component 212. The air guiding component 211 is used to guide the airflow within the air outlet section 12c1, and the drive component 212 is used to provide power for the operation of the air guiding component 211. The drive component 212 is located between the front panel 11 and the air outlet component 12. The air outlet component 12 defines two air outlet sections 12c1. The front panel 11 is located further away from the air duct than the air outlet component 12. Therefore, the drive component 212 is not located within the air outlet section 12c1. This arrangement can reduce the obstruction of the airflow by the drive component 212, thereby improving the airflow effect within the air outlet section 12c1.

[0152] The air guide assembly 211 includes multiple air guide vanes 2111 spaced apart in the vertical direction. The air guide vanes 2111 are adjustable in their vertical guiding angle to adjust the airflow upward or downward. It is worth noting that the adjustable vertical guiding angle of the air guide vanes 2111 enables multi-angle air guidance, further improving the air supply effect of the air conditioner 100.

[0153] By incorporating the air guide component 2, the vertical airflow range of the air conditioner 100 can be increased, thereby expanding its air outlet coverage area. Furthermore, during heat exchange, the heat exchange efficiency of the air conditioner 100 can be improved. For example, when the air conditioner 100 is cooling, cold air can be directed from above, preventing direct cold air from blowing onto the body; the cold air naturally sinks from top to bottom, enhancing the cooling effect. Similarly, when the air conditioner 100 is heating, hot air can be directed from below, first reaching the feet to warm them, alleviating the problem of a hot head and cold feet, and improving the body's steady-state thermal comfort.

[0154] This invention not only includes a third air outlet 1c for primary air supply, but also a first air outlet 1a and a second air outlet 1b that are higher than the third air outlet 1c. The air guide component 2 is located within the third air duct 12c, which is connected to both the first and second air ducts 12a and 12b. Therefore, when the air guide component 2 guides air vertically, it can direct airflow not only to the upper or lower part of the third air outlet 1c, but also to the first air outlet 1a or the second air outlet 1b. Compared to simply having a third air outlet 1c, this further increases the vertical air supply range of the air conditioner 100 and improves its air supply effect.

[0155] For example, when the air conditioner 100 is cooling, the air guide component 2 guides the air upward, and the cold air can be sent out from the upper part of the third air outlet 1c and the first air outlet 1a, which can improve the situation where the cold air blows directly on the human body. The cold air naturally sinks from top to bottom, improving the cooling effect. When the air conditioner 100 is heating, the air guide component 2 guides the air downward, and the hot air can be sent out from the lower part of the third air outlet 1c and the second air outlet 1b, so that the feet are warmed, improving the situation of hot head and cold feet, and improving the heating effect.

[0156] According to an embodiment of the present invention, the air conditioner 100, by providing a first air outlet 1a higher than the third air outlet 1c and a second air outlet 1b lower than the third air outlet 1c, guides the air in the vertical direction. This not only sends the airflow from the top or bottom of the third air outlet 1c, but also sends the air through the first air outlet 1a and the second air outlet 1b, thereby increasing the air supply range of the air conditioner 100 in the vertical direction. This is beneficial to increasing the air supply distance of the air conditioner 100, resulting in better air supply effect of the air conditioner 100.

[0157] In some embodiments of the present invention, such as Figure 19 As shown, the air outlet component 12 includes an upper air outlet component 123 located on the top of the air conditioner body 1. The upper air outlet component 123 includes an upper air outlet frame 1231 and an upper rotating door 1232. The upper air outlet frame 1231 defines a first air outlet 1a. The upper rotating door 1232 rotates and engages with the upper air outlet frame 1231 to switch whether the first air outlet 1a is emitting air.

[0158] The upper rotating door 1232 rotates to switch whether the first air outlet 1a is emitting air. When the upper rotating door 1232 rotates, it opens the first air outlet 1a, allowing airflow to be delivered through the first air outlet 1a. When the upper rotating door 1232 rotates, it closes the first air outlet 1a, preventing airflow from leaving the first air outlet 1a. The rotation of the upper rotating door 1232 is simple, which simplifies the drive structure of the upper air outlet component 123 and reduces manufacturing costs.

[0159] In some embodiments of the present invention, such as Figure 20As shown, the air conditioner body 1 includes a switching valve 14 disposed in the second air duct 12b. The switching valve 14 adjusts the on / off state of the second air duct 12b and the third air duct 12c by rotating, so as to switch whether the second air outlet 1b is emitting air.

[0160] When the switch valve 14 rotates to connect the second air duct 12b and the third air duct 12c, the airflow is sent out through the second air outlet 1b; when the switch valve 14 rotates to block the second air duct 12b and the third air duct 12c, the airflow can be prevented from being sent out through the second air outlet 1b.

[0161] In some other embodiments of the present invention, the air conditioner body 1 includes a switch valve 14 disposed at the second air outlet 1b. The switch valve 14 opens and closes the second air outlet 1b by rotation to switch whether the second air outlet 1b is emitting air.

[0162] Optionally, the switching valve 14 can also adjust the air outlet angle of the second air outlet 1b by rotation. The switching valve 14 swings in the vertical direction to adjust the air supply range of the second air outlet 1b in the vertical direction; or, the switching valve 14 swings in the horizontal direction to adjust the air supply range of the second air outlet 1b in the horizontal direction.

[0163] In other embodiments of the present invention, the switching valve 14 can also be used to switch the connection between the air duct and the second air duct 12b. Rotation of the switching valve 14 can connect the third air duct 12c with the second air duct 12b, so that the air supplied by the air conditioner can be sent out from the second air outlet 1b through the second air duct 12b; the switching valve 14 can also be rotated to connect other air ducts with the second air duct 12b, for example, connecting the fresh air duct with the second air duct 12b, so that fresh air is sent out from the second air outlet 1b, thereby improving the functionality of the air conditioner 100.

[0164] In some embodiments of the present invention, such as Figure 7 As shown, the air conditioner 100 also includes an air guide plate 3, which is located at the third air outlet 1c to switch whether the third air outlet 1c is emitting air.

[0165] In other embodiments of the invention, such as Figure 7 As shown, the air conditioner 100 also includes an air guide plate 3, which is located at the third air outlet 1c for guiding air left and right and for opening and closing the third air outlet 1c. The air guide plate 3 can be used not only for guiding air left and right, but also for opening and closing the third air outlet 1c.

[0166] The air guide plate 3 can guide air left and right to increase the air supply range of the air conditioner 100 in the horizontal direction, further improving the air supply effect of the air conditioner 100. When the air guide plate 3 opens the third air outlet 1c, the airflow is sent out through the third air outlet 1c and flows under the guidance of the air guide plate 3; when the air guide plate 3 closes the third air outlet 1c, it prevents the airflow from flowing out through the third air outlet 1c, and the air guide plate 3 can also prevent dust and other pollutants from entering the air conditioner body 1 through the third air outlet 1c, improving the cleanliness of the air conditioner 100.

[0167] In some embodiments of the present invention, the air conditioner 100 has a first state, a second state, and a third state. In the first state, the first air outlet 1a and the third air outlet 1c are open, and the guide vane 2111 is tilted upward at 15°-75°. In the second state, the second air outlet 1b and the third air outlet 1c are open, and the guide vane 2111 is tilted downward at 15°-75°. In the third state, the third air outlet 1c is open, and the guide vane 2111 is horizontal or tilted at less than 15°.

[0168] like Figure 5 and Figure 6 As shown, in the first state, the air conditioner 100 has its air guide vanes 2111 tilted upwards at 15°-75°. This increases the vertical airflow range of the air conditioner 100 and also improves its heat exchange efficiency. For example, in the first state, when the air conditioner 100 is in cooling mode, cold air can be sent out from the top of the first air outlet 1a and the third air outlet 1c. The cold air naturally sinks from top to bottom, improving the cooling effect.

[0169] Similarly, such as Figure 12 and Figure 13 As shown, in the second state, the air guide vanes 2111 of the air conditioner 100 are tilted downwards at 15°-75°, which can increase the air supply range of the air conditioner 100 in the vertical direction and improve the heat exchange effect of the air conditioner 100. For example, when the second state of the air conditioner 100 is the heating state, cold air can be sent out from the lower part of the second air outlet 1b and the third air outlet 1c, and hot air can be sent out from below, thus improving the heating effect.

[0170] In the third state, the air conditioner 100 delivers air horizontally along the third air outlet 1c or at a small angle in the vertical direction, which is the air delivery mode with the maximum air volume of the air conditioner 100.

[0171] The air guide vane 2111 can be adjusted up and down to guide the air, thus enabling multi-angle air guidance. The first air outlet 1a and the second air outlet 1b are both configured to switch between airflow and non-airflow. The cooperation between the air guide vane 2111 and the air outlet enables the air conditioner 100 to deliver air in multiple modes, thereby meeting the needs of different scenarios and improving the functionality of the air conditioner 100.

[0172] In some embodiments of the present invention, such as Figure 15 As shown, the air guide assembly 211 includes a connecting rod 2112, which extends in the vertical direction and is connected to a plurality of air guide vanes 2111 respectively. The middle part of the connecting rod 2112 has a driving part 21121 that cooperates with the driving assembly 212, so that a plurality of air guide vanes 2111 are distributed above and below the driving part 21121 respectively. The air guide vanes 2111 are flexible parts and are connected to the air outlet component 12, so that the air guide angle can be adjusted by pulling the air guide vanes 2111 to deform through the vertical movement of the connecting rod 2112.

[0173] The connecting rod 2112 is connected to multiple guide vanes 2111 respectively. The connecting rod 2112 is used to drive the multiple guide vanes 2111 to synchronously adjust the air guiding angle, thereby improving the overall airflow effect in the vertical direction and improving the air guiding effect of the air guiding component 2. Furthermore, by setting the connecting rod 2112, the drive assembly 212 only needs to be connected to the connecting rod 2112, which facilitates the arrangement of the drive assembly 212. The drive assembly 212 is connected to the drive part 21121 of the connecting rod 2112 to drive the connecting rod 2112 to move in the vertical direction.

[0174] The guide vane 2111 is a flexible component. The guide vane 2111 adjusts the upper and lower air guiding angles by deformation, which can improve the fatigue damage caused by the movement of the guide vane 2111 and help extend the service life of the guide vane 2111.

[0175] In related technologies, if the drive unit is located at one end of the connecting rod along its length, the guide vane connected to the other end of the connecting rod may not receive sufficient driving force and may not deform properly. This results in significant differences in the deformation of multiple guide vanes, which affects the airflow effect and is detrimental to the air guiding component.

[0176] In this invention, the driving part 21121 of the connecting rod 2112 is located in the middle of the connecting rod 2112, and the driving force received by the guide vanes 2111 connected to each other in the length direction is similar. This makes the deformation of multiple guide vanes 2111 similar, and the multiple guide vanes 2111 adjust the air guiding angle synchronously, which has a good guiding effect on the airflow and can improve the air guiding effect of the air guiding component 2.

[0177] In addition, by arranging the drive unit 21121 in the middle of the connecting rod 2112, the space occupied in the length direction of the connecting rod 2112 can be reduced, and the interference to the components on the length direction side of the connecting rod 2112 can be reduced.

[0178] It is worth noting that the air guiding component 2 includes two air guiding units 21, which are respectively set with two air outlet sections 12c1. The air guide vanes 2111 of each air guiding unit 21 synchronously adjust the air guiding angle to improve the air guiding effect. The two air guiding units 21 also work together, and the air guide vanes 2111 of the two air guiding units 21 are synchronously adjusted for air guiding calibration, which can further improve the air guiding effect of the air guiding component 2.

[0179] In some embodiments of the present invention, such as Figure 16 and Figure 17 As shown, the air guide component 2 includes a plurality of flexible blades 22 spaced apart in the vertical direction. The flexible blades 22 are integrally formed and include two blade portions 221 on the left and right sides. The two blade portions 221 are respectively disposed in the air outlet sections 12c1 on both sides, so that the blade portions 221 constitute the air guide blades 2111.

[0180] By integrating the two blade portions 221 located within the two air outlet sections 12c1 into a single unit, compared to the related technology where the two blades are installed separately within the air conditioner body, the flexible blade 22 of this invention can simultaneously install both blade portions 221 in a single installation, simplifying the assembly process and improving assembly efficiency. Furthermore, since the flexible blade 22 is a single molded component, connecting the left and right blade portions 221 increases the area of ​​the guide vane 2111, which is beneficial for improving the air guiding effect of the guide vane 2111.

[0181] In some embodiments of the present invention, such as Figure 17 As shown, the flexible blade 22 includes a connecting portion 222 connecting the two blade portions 221, and the connecting portion 222 is connected to the flow divider cone 122.

[0182] In some embodiments of the present invention, such as Figure 7 As shown, the air outlet component 12 includes a front frame 121 and a diverter cone 122. The diverter cone 122 is mounted on the front frame 121 and located at the intersection of the inlets of the two air outlet sections 12c1 to divert the airflow. The guide vane 2111 is connected to the diverter cone 122. Figure 8 and Figure 18 As shown, a vertically extending clearance opening 1211 is formed on the front frame 121. The drive assembly 212 is disposed between the front panel 11 and the air outlet component 12, and cooperates with the drive assembly 21121 through the transmission part 2124 passing through the clearance opening 1211.

[0183] The front frame 121 defines two air outlet sections 12c1. A diverter cone 122 is installed on the front frame 121. The diverter cone 122 is located in the third air duct 12c and at the intersection of the inlets of the two air outlet sections 12c1. The diverter is used to divert the airflow and guide the airflow to the two air outlet sections 12c1 respectively.

[0184] The air guide vane 2111 is installed on the flow divider cone 122. The air guide vane 2111 and the flow divider cone 122 are first integrated and then assembled with the air conditioner body 1 as a whole, which can simplify the assembly process and improve the assembly efficiency.

[0185] The front panel 11 is located in front of the air outlet component 12. The outlet of the air outlet section 12c1 extends forward to the left and right sides of the front panel 11 to communicate with the third air outlet 1c on the left and right sides of the front panel 11. The drive assembly 212 is located between the front panel 11 and the front frame 121. The drive assembly 212 is not located inside the air outlet section 12c1, which can improve the airflow obstruction of the drive assembly 212, thereby improving the airflow effect in the air outlet section 12c1. The connecting rod 2112 is located on the front side of the guide vane 2111, that is, the connecting rod 2112 is connected to the end of the guide vane 2111 that is away from the diverter cone 122. The connecting rod 2112 is located closer to the drive assembly 212 than the guide vane 2111, which facilitates the connection between the drive assembly 212 and the drive part 21121 of the connecting rod 2112, reduces the difficulty of arranging the drive assembly 212, and avoids the connection between the drive assembly 212 and the connecting rod 2112 from interfering with the movement of the guide vane 2111, thereby improving the working reliability of the guide vane 2111.

[0186] The drive assembly 212 is located between the front panel 11 and the front frame 121. The front frame 121 has a vertically extending clearance opening 1211. The drive assembly 212 also includes a transmission part 2124, which extends from the clearance opening 1211 into the air outlet section 12c1 to cooperate with the drive part 21121. The drive assembly 212 can thus drive the connecting rod 2112 to move in the vertical direction.

[0187] In some embodiments of the present invention, such as Figure 18 As shown, the drive unit 21121 is annular, and the transmission unit 2124 extends into the annular hole of the drive unit 21121. The transmission unit 2124 is not easily dislodged from the drive unit 21121, thus improving the reliability of the fit between the transmission unit 2124 and the drive unit 21121.

[0188] In some embodiments of the present invention, such as Figure 9 and Figure 16 As shown, the drive assembly 212 includes: a motor 2121, a gear 2122, and a rack 2123. The motor 2121 is connected to the gear 2122, the gear 2122 meshes with the rack 2123, and the rack 2123 extends in the vertical direction and cooperates with the transmission part 2124, as shown. Figure 10 and Figure 16 As shown, the motor 2121 is located on the side of the rack 2123 near the splitter cone 122.

[0189] Motor 2121 is a power component. The motor shaft of motor 2121 is connected to gear 2122. The rotation of motor shaft 2121 drives gear 2122 to rotate. Gear 2122 meshes with rack 2123, and rack 2123 moves vertically under the meshing action of gear 2122. Transmission part 2124 is connected to rack 2123. The movement of rack 2123 drives transmission part 2124 to move. Transmission part 2124 cooperates with drive part 21121 to drive connecting rod 2112 to move vertically.

[0190] The gear 2122 and rack 2123 have a simple structure and strong reliability, which can improve the working stability of the drive component 212; and the arrangement of the gear 2122 and rack 2123 occupies little space, which is beneficial to the arrangement of the drive component 212.

[0191] like Figure 7 and Figure 16 As shown, the two inlet ends of the flow divider cone 122 are connected at the intersection of the inlets of the two outlet sections 12c1. The two outlet ends of the flow divider cone 122 extend away from each other and towards the left and right outlet sections 12c1 respectively to guide the airflow to the two outlet sections 12c1. Therefore, the gap between the intersection of the inlet ends of the flow divider cone 122 and the outlet component 12 is larger than the gap between the outlet end of the flow divider cone 122 and the outlet component 12. The motor 2121 is located on the side of the rack 2123 closer to the flow divider cone 122, which is beneficial for the installation and arrangement of the motor 2121 and can also reduce the occupation of the drive assembly 212 on the internal space of the outlet component 12, which is beneficial for the flow of air in the outlet component 12.

[0192] In some embodiments of the present invention, such as Figure 10 As shown, the flow divider cone 122 has a clearance portion 1221 disposed away from the flow divider cone 122 to avoid the installation of the motor 2121.

[0193] In some embodiments of the present invention, such as Figure 16 As shown, the drive assembly 212 also includes a mounting base 2125, which is mounted on the front frame 121 and located between the front panel 11 and the front frame 121. The motor 2121, gear 2122 and rack 2123 are all mounted on the mounting base 2125.

[0194] The transmission part 2124 on the rack 2123 passes through the air outlet component 12 to engage with the connecting rod 2112 in the air duct. The rack 2123 is mounted on the side of the mounting base 2125 away from the front frame 121. Therefore, the transmission part 2124 on the rack 2123 also extends rearward through the mounting base 2125 to engage with the drive part 21121 of the connecting rod 2112 in the air duct.

[0195] In some embodiments of the present invention, such as Figure 7 The air conditioner 100 includes a cross-flow fan 4, and the air conditioner body 1 also has a cross-flow duct 15. The cross-flow fan 4 is arranged in the cross-flow duct 15 and provides airflow. The first duct 12a, the second duct 12b, and the third duct 12c are located downstream of the cross-flow duct 15. Due to the air outlet shape of the cross-flow fan 4, the cross-flow duct 15 has a volute, and the air outlet direction of the cross-flow duct 15 is biased towards one of the two third air outlets 1c. By setting a flow divider cone 122, the airflow to the two air outlet sections 12c1 can be made relatively uniform, so that the air supply volume of the two third air outlets 1c is balanced, thereby improving the air supply effect of the air conditioner 100.

[0196] According to some embodiments of the air conditioner 100 of the present invention, the air outlet angle of the third air outlet 1c in the vertical direction is adjusted by the air guide component 2, as described below. Figure 1 This describes the operation process of an air conditioner 100 according to an embodiment of the present invention entering a first mode using the control method of a first aspect embodiment.

[0197] First, control the air guide vane 2111 to be horizontal, close the first air outlet 1a and the second air outlet 1b, and control the third air outlet 1c to deliver air horizontally. At this time, the air conditioner 100 delivers air from the third air outlet 1c on both the left and right sides, with the maximum air volume.

[0198] Next, the system enters the first mode, the air conditioner 100 executes the cooling command, the air conditioner 100 obtains the indoor temperature, and obtains the difference between the indoor temperature and the first preset temperature.

[0199] Then, the air conditioner 100 opens the first air outlet 1a and adjusts the upward deflection angle of the guide vane 2111 according to the first temperature difference to adjust the air outlet angle of the third air outlet 1c in the vertical direction.

[0200] When the first temperature difference is higher than the first temperature threshold, it indicates that the indoor temperature is high and needs to be cooled down quickly. At this time, the motor 2121 drives the guide vane 2111 to deflect upward at a small angle, controlling the third air outlet 1c to deliver air at a relatively horizontal upward tilt at a small first angle. The air volume of the third air outlet 1c is larger than that of the first air outlet 1a, so the air volume is prioritized to ensure the air volume and provide strong cooling.

[0201] When the first temperature difference is lower than the first temperature threshold and higher than the second temperature threshold, it indicates that the indoor temperature is high and cooling is needed while also reducing the feeling of airflow. At this time, the motor 2121 drives the guide vane 2111 to deflect upward at a moderate angle, controlling the third air outlet 1c to deliver air at a relatively horizontal and upward tilted second angle. The air volume of the third air outlet 1c decreases, while the air volume of the first air outlet 1a increases, ensuring the air volume while reducing the feeling of direct airflow.

[0202] When the first temperature difference is lower than the second temperature threshold, it indicates that the indoor temperature is relatively suitable. To maintain the indoor temperature and further reduce the feeling of draft, the third air outlet 1c is controlled to deliver air at a relatively large upward tilt. The air volume of the third air outlet 1c is relatively small, while the air volume of the first air outlet 1a continues to increase. The cool air passes over the user's body, reducing the feeling of direct airflow and increasing the air delivery distance, accelerating the air circulation in the room, reducing the temperature difference in various places, and improving the heat exchange effect.

[0203] Finally, the air conditioner 100 maintains the air outlet angle of the third air outlet 1c in the vertical direction and detects the first temperature difference in real time. When the relationship between the first temperature difference and the first temperature threshold and the second temperature threshold changes, the air conditioner 100 adjusts the air outlet angle of the third air outlet 1c in the vertical direction according to the first temperature difference at this time.

[0204] When the first mode is entered, during the process of the air conditioner 100 executing the cooling command, after detecting that the first temperature difference is higher than the first temperature threshold, without interfering with the air conditioner 100, the air conditioner 100 will control the third air outlet 1c to deliver air at a first angle that is relatively horizontally upward, then control the third air outlet 1c to deliver air at a second angle that is relatively horizontally upward, and finally control the third air outlet 1c to deliver air at a third angle that is relatively horizontally upward and maintain it.

[0205] The following is for reference. Figure 2 This describes the operation process of an air conditioner 100 according to an embodiment of the present invention entering a second mode using the control method of the first aspect embodiment.

[0206] First, control the air guide vane 2111 to be horizontal, close the first air outlet 1a and the second air outlet 1b, and control the third air outlet 1c to deliver air horizontally. At this time, the air conditioner 100 delivers air from the third air outlet 1c on both the left and right sides, with the maximum air volume.

[0207] Next, the system enters the second mode, and the air conditioner 100 executes the heating command. The air conditioner 100 obtains the indoor temperature and gets the difference between the indoor temperature and the third preset temperature.

[0208] Then, the air conditioner 100 opens the second air outlet 1b and adjusts the downward deflection angle of the guide vane 2111 according to the second temperature difference to adjust the air outlet angle of the third air outlet 1c in the vertical direction.

[0209] When the second temperature difference is higher than the third temperature threshold, it indicates that the indoor temperature is low and needs to be heated quickly. At this time, the motor 2121 drives the guide vane 2111 to deflect upward at a small angle, and controls the third air outlet 1c to deliver air at a relatively horizontal downward tilt at a small fourth angle. The air volume of the third air outlet 1c is larger, while the air volume of the second air outlet 1b is smaller, so the air volume is prioritized to ensure strong heating.

[0210] When the second temperature difference is lower than the third temperature threshold but higher than the fourth temperature threshold, it indicates that the indoor temperature is low. It is necessary to raise the temperature while also reducing the feeling of air blowing. At this time, the motor 2121 drives the guide vane 2111 to deflect downward at a moderate angle, controlling the third air outlet 1c to deliver air at a relatively horizontal and downward tilted fifth angle. The air volume of the third air outlet 1c decreases, while the air volume of the second air outlet 1b increases, ensuring the air volume while reducing the feeling of direct airflow.

[0211] When the second temperature difference is lower than the fourth temperature threshold, it indicates that the indoor temperature is relatively suitable. To maintain the indoor temperature and further reduce the feeling of draft, the third air outlet 1c is controlled to supply air at a relatively large downward tilt at the sixth angle. The air volume of the third air outlet 1c is relatively small, while the air volume of the second air outlet 1b continues to increase. This ground-level heating reduces the indoor temperature difference and improves the heat exchange effect.

[0212] Finally, the air conditioner 100 maintains the air outlet angle of the third air outlet 1c in the vertical direction and detects the second temperature difference in real time. When the relationship between the second temperature difference and the third and fourth temperature thresholds changes, the air conditioner 100 adjusts the air outlet angle of the third air outlet 1c in the vertical direction according to the second temperature difference at this time.

[0213] In the second mode, when the air conditioner 100 executes the heating command, after detecting that the second temperature difference is higher than the third temperature threshold, without interfering with the air conditioner 100, the air conditioner 100 will control the third air outlet 1c to deliver air at a fourth angle that is relatively horizontally downward, then control the third air outlet 1c to deliver air at a fifth angle that is relatively horizontally downward, and finally control the third air outlet 1c to deliver air at a sixth angle that is relatively horizontally downward and maintain it.
