Description

Technical Field

[0001] This invention relates to the field of air conditioning, and in particular to a control method for an air conditioner and an air conditioner. Background Technology

[0002] In related technologies, when an air conditioner is in "windless mode," the airflow speed decreases significantly in areas farther from the unit. For example, at a distance of about 2 meters from the unit, the airflow speed may drop to 0.3 m / s. This results in poor temperature regulation for areas further away. Prolonged operation in "windless mode" leads to a large temperature difference between areas near and far from the unit, resulting in uneven temperature distribution within the room and reduced user comfort. Therefore, improvements are needed. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of this invention is to provide a control method for an air conditioner, which sets the air conditioner's windless mode to include a first windless state and a second windless state with different states. By making the obstruction area of ​​the air outlet in the second windless state smaller than that in the first windless state, the air outlet resistance in the second windless state is reduced compared to that in the first windless state. This allows for a faster airflow speed and a larger air outlet area in the second windless state, resulting in a longer air delivery distance. By cyclically switching between the first and second windless states in the windless mode, the air conditioner can switch between a lower airflow speed (avoiding direct blowing) and a larger air outlet area (allowing for a longer air delivery distance), avoiding direct blowing while simultaneously ensuring airflow to both near and far areas, thus improving the uniformity of temperature distribution in the room.

[0004] The present invention also proposes an air conditioner that operates according to the control method of the above-described air conditioner.

[0005] According to a first aspect of the present invention, the air conditioner has an air outlet and an air outlet channel communicating with the air outlet. A first air guide mechanism is provided in the air outlet channel, and a diffuser structure is formed on the first air guide mechanism. The air conditioner has a windless mode, which includes a first windless state and a second windless state. The first air guide mechanism obstructs the air outlet in the second windless state, but the obstruction area is smaller in the first windless state than in the first windless state. The control method of the air conditioner includes: controlling the air conditioner to enter the windless mode; and in the windless mode, controlling the air conditioner to cyclically switch between the first windless state and the second windless state.

[0006] According to the air conditioner control method of the present invention, by making the obstruction area of ​​the air outlet of the air conditioner in the second windless state smaller than that in the first windless state, the air outlet resistance of the air conditioner in the second windless state is reduced compared to that in the first windless state. This results in a larger outlet area compared to the first windless state, allowing for a faster airflow speed and a larger airflow area in the second windless state, thus extending the air delivery distance. Furthermore, by cyclically switching between the first and second windless states in the windless mode, the air conditioner can switch between a lower airflow speed (avoiding direct blowing) and a larger airflow area (extending the air delivery distance), avoiding direct blowing while simultaneously ensuring airflow to both near and far areas, thereby improving the uniformity of temperature distribution within the room.

[0050] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0051] The following is for reference. Figures 1-8 A control method for an air conditioner according to an embodiment of the present invention is described.

[0052] According to a control method for an air conditioner based on a first aspect of the present invention, the air conditioner has an air outlet 40 and an air outlet duct 50 communicating with the air outlet 40. A first air guide fan 31 is provided within the air outlet duct 50, and a diffuser structure is formed on the first air guide fan 31. The air conditioner has a windless mode. In the windless mode, the first air guide fan 31 blocks at least a portion of the air outlet 40. When airflow passes through the air outlet 40, the airflow is dispersed by the diffuser structure on the first air guide fan 31, avoiding discomfort caused by direct airflow.

[0053] For example, the first air guide 31 includes multiple first air guide plates 61 arranged vertically. Each first air guide plate 61 is rotatable, and the vertical rotation of the first air guide plate 61 can guide the airflow up and down to the air outlet 40. Each first air guide plate 61 has multiple air diffuser holes 62. The air diffuser structure includes multiple air diffuser holes 62. When the first air guide plate 61 of the first air guide 31 blocks the air outlet 40, the airflow can be dispersed through the multiple air diffuser holes 62 on the first air guide plate 61, avoiding the discomfort caused by direct airflow and achieving a windless effect. Furthermore, the first air guide 31 may also include a first connecting rod 70 and a connecting rod motor. The first connecting rod 70 extends vertically, and each first air guide plate 61 is rotatably connected to the first connecting rod 70. The connecting rod motor is connected to the first connecting rod 70 to drive the first connecting rod 70 to move up and down. The vertical movement of the first connecting rod 70 causes the first air guide plate 61 to swing up and down.

[0054] The windless mode includes a first windless state and a second windless state. In the second windless state, the obstruction area of ​​the first fan 31 around the air outlet 40 is smaller than that in the first windless state. When the air conditioner is in the first windless state, the obstruction area of ​​the first fan 31 around the air outlet 40 is larger. This allows more airflow at the air outlet 40 to be dispersed by the air diffuser structure on the first fan 31, achieving a better windless effect and more effectively preventing direct airflow onto the user. However, in the first windless state, the air velocity from the air outlet 40 is lower and the air outlet area is smaller, limiting its temperature regulation capability for areas farther from the unit. When the air conditioner is in the second windless state, the air resistance of the first air guide fan 31 to the air outlet 40 is reduced, so the air outlet speed can be increased and the air delivery distance can be longer compared to the first windless state. Due to the small obstruction area, the air outlet 40 of the air conditioner is larger in the second windless state, which enhances the air conditioner's ability to regulate the temperature of areas farther away from the air conditioner.

[0055] For example, in the first windless state, the first air guide fan 31 completely blocks the air outlet 40; in the second windless state, the first air guide fan 31 partially blocks the air outlet 40. As another example, in the first windless state, the first air guide fan 31 partially blocks the air outlet 40; in the second windless state, the first air guide fan 31 partially blocks the air outlet 40, and the area of ​​the air outlet 40 blocked by the first air guide fan 31 is smaller than that in the first windless state.

[0056] Air conditioner control methods include:

[0057] Control the air conditioner to enter the draftless mode;

[0058] In windless mode, the air conditioner cycles between the first windless state and the second windless state.

[0059] For example, when the windless mode is turned on, the air conditioner is controlled to enter the first windless state. After the air conditioner remains in the first windless state for a period of time, it switches to the second windless state. After the air conditioner remains in the second windless state for a period of time, it switches back to the first windless state, and so on in a cycle.

[0060] By allowing the air conditioner to cycle between a first windless state and a second windless state in a windless mode, the air conditioner can more significantly disperse the airflow at the air outlet 40 through the air distribution structure on the first air guide fan 31 in the first windless state, achieving a better windless effect and avoiding direct blowing. In the second windless state, the air conditioner can deliver air a longer distance than in the first windless state. This allows the air conditioner to switch between states that fully avoid direct blowing and deliver air a longer distance, thus avoiding direct blowing while taking into account both the air delivery near and far from the air conditioner, improving the uniformity of temperature distribution in the room.

[0061] According to the control method of the air conditioner of the present invention, by making the obstruction area of ​​the air outlet 40 of the air conditioner in the second windless state smaller than that in the first windless state, the air outlet resistance of the air conditioner in the second windless state is reduced compared to that in the first windless state. In this way, the outlet area is larger than that in the first windless state, which allows the air outlet speed of the air conditioner in the second windless state to be faster and the air outlet area 65 to be larger, resulting in a longer air delivery distance. By cyclically switching between the first and second windless states in the windless mode, the air conditioner can switch between a lower air speed and a larger air outlet area 65 and a longer air delivery distance, avoiding direct airflow while ensuring air delivery to both near and far areas, thereby improving the uniformity of temperature distribution in the room.

[0062] According to some embodiments of the present invention, with reference to Figure 3 and Figure 4 The air outlet 40 includes a first air outlet area 41 and a second air outlet area 42. The first air outlet area 41 is located above the second air outlet area 42. The area of ​​the first air guide fan 31 blocking the first air outlet area 41 in the second windless state is smaller than the area of ​​the first air outlet area 41 in the first windless state. Because the first air outlet area 41 is located higher, by making the area of ​​the first air guide fan 31 blocking the first air outlet area 41 in the second windless state smaller than the area of ​​the first air outlet area 41 in the first windless state, the air outlet speed of the first air outlet area 41 located higher in the second windless state can be faster, making it easier to throw the airflow upward and far away, resulting in a longer air delivery distance. The air conditioner can more easily deliver air to a long distance and can better regulate the temperature of areas far from the air conditioner.

[0063] For example, in the first windless state, the first air guide fan 31 completely blocks the first air outlet area 41, and the air dispersion structure on the first air guide fan 31 can more fully disperse the airflow to achieve a better windless effect; in the second windless state, the first air guide fan 31 partially blocks the air outlet area, and the air conditioner can throw the airflow upward and far away, which makes it easier for the air conditioner to send air to a farther place and can better regulate the temperature of areas far away from the air conditioner.

[0064] According to some embodiments of the present invention, with reference to Figure 3 The first air guide fan 31 blocks the second air outlet area 42 in the second windless state with the same area as in the first windless state. Since the second air outlet area 42 is located below the air conditioner, its impact on the long-distance airflow is minimal. By ensuring that the first air guide fan 31 blocks the second air outlet area 42 in the second windless state with the same area as in the first windless state, the airflow in the second air outlet area 42 is effectively dispersed by the air distribution structure in the second windless state, ensuring the air conditioner maintains a good windless effect and improving the user experience when the ambient temperature changes. Furthermore, it also prevents this airflow from blowing directly onto the legs, further enhancing the user experience.

[0065] According to some embodiments of the present invention, with reference to Figure 8 The first air guide 31 includes multiple first air guide plates 61 arranged vertically. Each first air guide plate 61 is rotatable, and the vertical rotation of the first air guide plate 61 can guide the airflow up and down to the air outlet 40. Each first air guide plate 61 has multiple air dispersion structures, including multiple air dispersion holes 62. When the first air guide plate 61 of the first air guide 31 blocks the air outlet 40, the airflow can be dispersed through the multiple air dispersion holes 62 on the first air guide plate 61, avoiding the discomfort caused by direct airflow and achieving a windless effect.

[0066] Multiple first air guide plates 61 are divided into an upper air guide plate group 63 and a lower air guide plate group 64. The upper air guide plate group 63 is located above the lower air guide plate group 64. Both the upper air guide plate group 63 and the lower air guide plate group 64 include at least one first air guide plate 61. By forming multiple air diffusers 62 on each first air guide plate 61, airflow can be blown out from the air diffusers 62 when the first air guide plate 61 is in the closed air outlet 40 state. This allows the air conditioner to regulate the temperature while fully dispersing the airflow to achieve a draft-free effect.

[0067] For example, the upper air guide plate assembly 63 corresponds to the first air outlet area 41, and the lower air guide plate assembly 64 corresponds to the second air outlet area 42. Both the upper air guide plate assembly 63 and the lower air guide plate assembly 64 include at least one first air guide plate 61. The first air guide fan 31 blocks the first air outlet area 41 in the second windless state, but the blocking area of ​​the first air guide fan 31 on the second air outlet area 42 in the second windless state is the same as the blocking area in the first windless state.

[0068] In the first windless state, the angle between the first air guide plate 61 of the upper air guide plate assembly 63 and the air outlet surface 65 is the first angle. In the second windless state, the angle between the first air guide plate 61 of the upper air guide plate assembly 63 and the air outlet surface 65 is the second angle, which is greater than the first angle. The air outlet surface 65 is the plane where the air outlet 40 is located. By making the second angle greater than the first angle, in the first windless state, the first air guide fan 31 structure has a larger obstruction area on the first air outlet area 41, and the airflow is fully dispersed by the air dispersion structure on the first air guide fan 31 structure, which can more significantly reduce the feeling of wind. In the second windless state, the first air guide fan 31 structure has a smaller obstruction area on the first air outlet area 41, and the air outlet surface 65 of the first air outlet area 41 is larger. At this time, the air conditioner can send air to a farther distance and can better regulate the temperature of areas farther away from the air conditioner.

[0069] For example, the first air guide 31 may also include a first link 70 and a link motor. The first link 70 extends in the vertical direction, and each first air guide plate 61 is rotatably connected to the first link 70. The link motor is connected to the first link 70 to drive the first link 70 to move up and down. The up and down movement of the first link 70 drives the first air guide plate 61 to swing up and down.

[0070] Furthermore, the first connecting rod 70 may include an upper connecting rod 71 and a lower connecting rod 72. Each first air guide plate 61 in the upper air guide plate assembly 63 is rotatably connected to the upper connecting rod 71, and each first air guide plate 61 in the lower air guide plate assembly 64 is rotatably connected to the lower connecting rod 72. The connecting rod motor may include an upper connecting rod motor 73 and a lower connecting rod motor 74. The upper connecting rod motor 73 is connected to the upper connecting rod 71 to drive the upper connecting rod 71 to move in the up-down direction, thereby causing each first air guide plate 61 in the upper air guide plate assembly 63 to swing up and down. The lower connecting rod motor 74 is connected to the lower connecting rod 72 to drive the lower connecting rod 72 to move in the up-down direction, thereby causing each first air guide plate 61 in the lower air guide plate assembly 64 to swing up and down. The upper connecting rod motor 73 and the lower connecting rod motor 74 can be controlled independently, thus allowing the upper air guide plate assembly 63 and the lower air guide plate assembly 64 to be controlled independently.

[0071] According to some embodiments of the present invention, the difference between the second included angle and the first included angle ranges from 5° to 20°. For example, the difference between the second included angle and the first included angle can be 5°, 10°, 15°, 20°, etc. By making the difference between the second included angle and the first included angle greater than 5°, the difference in the blocking area of ​​the first air outlet area 41 by the first air guide fan 31 in the first windless state and the second windless state can be sufficiently large, so that the air conditioner can deliver air to a distance more fully in the second windless state and more fully regulate the temperature of the area farther away from the air conditioner; by making the difference between the second included angle and the first included angle less than 20°, while ensuring that the air conditioner delivers air to a distance fully, the blocking area of ​​the air outlet 40 can be ensured to avoid the air volume of the air conditioner being too large and causing discomfort to the user in the second windless state, thus ensuring the windless effect in the second windless state.

[0072] According to some embodiments of the present invention, the first included angle ranges from 0° to 5°, and the second included angle ranges from 5° to 20°. By making the first included angle range from 0° to 5°, the first air guide fan 31 can sufficiently reduce the area of ​​the air outlet 40 in the first windless state, so that the blown airflow is fully dispersed, and the wind sensation can be reduced more significantly. By making the second included angle range from 5° to 20°, the air conditioner can deliver air to a farther distance, better regulate the temperature of areas farther from the air conditioner, and ensure that the air conditioner delivers air to a greater distance while reducing the area of ​​the air outlet 40, dispersing the blown airflow, and avoiding excessive airflow from the air conditioner in the second windless state, which would cause discomfort to the user.

[0073] According to some embodiments of the present invention, in the second windless state, the first air guide plate 61 of the upper air guide plate assembly 63 extends upward at an angle from back to front. By making the first air guide plate 61 of the upper air guide plate assembly 63 extend upward at an angle from back to front in the second windless state, the first air guide plate 61 of the upper air guide plate assembly 63 can guide the airflow upward and throw the airflow blown out of the air outlet 40 upward. This allows the air conditioner to deliver air to a distance more effectively and better regulate the temperature of areas far from the air conditioner.

[0074] According to some embodiments of the present invention, with reference to Figures 3-5In the first windless state, the angle between the first air guide plate 61 of the lower air guide plate assembly 64 and the air outlet surface 65 is the third angle. In the second windless state, the angle between the first air guide plate 61 of the lower air guide plate assembly 64 and the air outlet surface 65 is the fourth angle, which is the same as the third angle. Since the air outlet 40 area corresponding to the lower air guide plate assembly 64 is located below the air conditioner, this area has little impact on the long-distance air delivery of the air conditioner. By making the fourth angle the same as the third angle, the area of ​​the air outlet 40 of the second air outlet area 42 of the air conditioner is smaller in both the first and second windless states. The blown air can be fully dispersed, ensuring that the air conditioner significantly reduces the feeling of draft and improves the user experience when changing the ambient temperature. Furthermore, it also prevents this part of the air from blowing directly on the legs, improving the user experience.

[0075] According to some embodiments of the present invention, the range of the third or fourth included angle is 0° to 5°. Since the air outlet 40 area corresponding to the lower air guide plate assembly 64 is located below the air conditioner, this area has little impact on the long-distance air delivery of the air conditioner. By making the range of the third and fourth included angles 0° to 5°, the first air guide plate 61 of the lower air guide plate assembly 64 can sufficiently reduce the area of ​​the air outlet 40 when there is no wind, so that the blown airflow is more fully dispersed, and the air conditioner can more significantly reduce the wind sensation; in addition, it can also prevent this part of the wind from blowing directly on the legs, enhancing the user's comfort.

[0076] For example, in the first windless state, the included angle between the first air guide plate 61 of the lower air guide plate assembly 64 and the air outlet surface 65 is the third included angle, which is the same as the first included angle.

[0077] According to some embodiments of the present invention, with reference to Figure 6 and Figure 7 The air conditioner has a normal air outlet mode. In this mode, the angle between the first air guide plate 61 and the air outlet surface 65 is the fifth angle, which is greater than the second angle. By making the fifth angle greater than the second angle, the air conditioner can have sufficient airflow in the normal air outlet mode, thus enhancing its temperature control capability.

[0078] According to some embodiments of the present invention, the fifth included angle is in the range of 80° to 90°. By making the fifth included angle not less than 80°, the first air guide plate 61 can less obstruct the air outlet 40 in the normal air outlet mode, the air outlet 40 has a larger air outlet surface 65 area, the air conditioner has sufficient air volume, and the air conditioner has sufficient temperature regulation capability.

[0079] In some embodiments, refer to Figure 8The first air guide fan 31 also includes a rotatable rotating cylinder 66, the rotation axis of which extends in the vertical direction. The rotating cylinder 66 includes a plurality of grating ribs 67 arranged circumferentially along the rotating cylinder 66, the grating ribs 67 extending in the vertical direction. A plurality of first air guide plates 61 are disposed inside the rotating cylinder 66 and rotatably connected to the rotating cylinder 66. The air conditioner has a normal air outlet mode. In the normal air outlet mode, the grating ribs 67 are closer to the air outlet 40 than the first air guide plates 61. In the windless mode, the first air guide plates 61 are closer to the air outlet 40 than the grating ribs 67.

[0080] For example, the first air guide 31 may also include a first connecting rod 70 and a connecting rod motor. The first connecting rod 70 extends in the vertical direction and passes through the rotating drum 66 in the vertical direction and is movable in the vertical direction. Each first air guide plate 61 is rotatably connected to the first connecting rod 70. The connecting rod motor is connected to the first connecting rod 70 to drive the first connecting rod 70 to move up and down. The up and down movement of the first connecting rod 70 drives the first air guide plate 61 to swing up and down.

[0081] Furthermore, the rotating drum 66 may include an upper rotating drum 68 and a lower rotating drum 69 arranged vertically. The rotation axes of the upper rotating drum 68 and the lower rotating drum 69 may be coaxially arranged. The upper air guide plate assembly 63 is located in the upper rotating drum 68 located on the upper side, and the lower air guide plate assembly 64 is located in the lower rotating drum 69 located on the lower side. The air conditioner may include two rotating drum motors, namely an upper rotating drum motor and a lower rotating drum motor. The upper rotating drum motor is located on the upper side of the upper rotating drum 68 and connected to the upper rotating drum 68 to drive the upper rotating drum 68 to rotate. The lower rotating drum motor is located on the lower side of the lower rotating drum 69 and connected to the lower rotating drum 69 to drive the lower rotating drum 69 to rotate.

[0082] The first guide fan 31 may further include a first connecting rod 70 and a connecting rod motor. The first connecting rod 70 extends in the vertical direction, and each first guide plate 61 is rotatably connected to the first connecting rod 70. The connecting rod motor is connected to the first connecting rod 70 to drive the first connecting rod 70 to move up and down. The vertical movement of the first connecting rod 70 causes the first guide plate 61 to swing up and down. The first connecting rod 70 may include an upper connecting rod 71 and a lower connecting rod 72. The connecting rod motor may include an upper connecting rod motor 73 and a lower connecting rod motor 74. The upper connecting rod motor 73 is located on the upper side of the upper rotating cylinder 68 and is connected to the upper connecting rod 71 to drive the upper connecting rod 71 to move in the vertical direction. The lower connecting rod motor 74 is located on the lower side of the lower rotating cylinder 69 and is connected to the lower connecting rod 72 to drive the lower connecting rod 72 to move in the vertical direction.

[0083] Optionally, the lower end of the upper link 71 can be connected to the upper end of the lower link 72 via a flexible element.

[0084] According to some embodiments of the present invention, with reference to Figure 4 and Figure 7The air outlet duct 50 is also equipped with a second air guide 31 structure. The second air guide 31 structure is located upstream of the first air guide 31 structure. The second air guide 31 structure includes multiple second air guide plates 81 arranged in the vertical direction. Each second air guide plate 81 can rotate. In the second windless state, the second air guide plate 81 extends upward in the direction from back to front. By positioning the second air guide fan 31 upstream of the first air guide fan 31, the second air guide fan 31 can work in conjunction with the first air guide fan 31 to guide the airflow. By including multiple second air guide plates 81 arranged vertically, the air outlet 50 of the air conditioner can be guided by the second air guide plates 81 in both vertical and horizontal directions. By extending the second air guide plates 81 upwards from back to front in the second windless state, the second air guide plates 81 can guide the airflow forward and upward, making it easier for the airflow blown out of the air outlet 40 to be thrown upwards. This allows the air conditioner to deliver air to distant areas more effectively and better regulate the temperature of areas far from the air conditioner.

[0085] For example, the second air guide 31 may also include a second link 82, which extends in the vertical direction. Each second air guide plate 81 is rotatably connected to the second link 82. The second link 82 can move up and down, and the second air guide plate 81 swings up and down through the up and down movement of the second link 82.

[0086] According to some embodiments of the present invention, in the second windless state, the angle between the second air guide plate 81 and the air outlet surface 65 is a sixth angle, which is greater than the second angle. By making the sixth angle greater than the second angle, the second air guide plate 81 can effectively guide the airflow forward and upward, facilitating the upward ejection of the airflow from the air outlet 40 while reducing the obstruction of the airflow by the second air guide plate 81, and avoiding insufficient airflow due to excessive wind blocking by the second air guide plate 81.

[0087] According to some embodiments of the present invention, the value of the sixth included angle is in the range of 35° to 60°. For example, the value of the sixth included angle can be 35°, 40°, 45°, 50°, 55°, 60°, etc. By making the sixth included angle not less than 35°, the obstruction of the airflow by the second air guide plate 81 can be reduced, and the insufficient airflow caused by the second air guide plate 81 blocking the wind excessively can be avoided; by making the sixth included angle not greater than 60°, the second air guide plate 81 can more fully guide the airflow forward and upward, making it easier for the airflow blown out from the air outlet 40 to be thrown upward.

[0088] According to some embodiments of the present invention, the rotational speed of the air conditioner fan 31 in the second windless state is greater than that in the first windless state. By making the rotational speed of the air conditioner fan 31 in the second windless state greater than that in the first windless state, the air volume and air speed of the air conditioner in the second windless state can be increased, enabling the air conditioner to blow more airflow to a farther distance, and the air conditioner to more effectively regulate the temperature of areas farther away from the air conditioner.

[0089] According to some embodiments of the present invention, the fan 31 rotates at a speed of 700-900 rpm / min in the first windless state and at a speed greater than 1000 rpm / min in the second windless state. For example, the fan 31 can rotate at 700 rpm / min, 750 rpm / min, 800 rpm / min, 850 rpm / min, 900 rpm / min, etc. By ensuring that the fan 31 rotates at no more than 900 rpm / min in the first windless state, the airflow speed of the air conditioner in the first windless state can be appropriately reduced, avoiding discomfort caused by excessively fast airflow. By ensuring that the fan 31 rotates at no less than 700 rpm / min in the first windless state, the air conditioner can achieve sufficient temperature control, avoiding reduced temperature control due to insufficient airflow. For example, the fan 31 can rotate at 1000 rpm / min, 1100 rpm / min, 1200 rpm / min, etc. in the second windless state. By increasing the speed of the fan 31 to more than 1000 rpm / min in the second windless state, the air volume of the air conditioner in the second windless state can be increased, enabling the air conditioner to blow air further away and more effectively regulate the temperature of areas further away from the air conditioner.

[0090] For example, the air conditioner has a normal air outlet mode, in which the fan speed 31 is greater than 1000 rpm / min.

[0091] According to some embodiments of the present invention, the duration of a single cycle of operation of the air conditioner in the first windless state is greater than or equal to the duration of a single cycle of operation of the air conditioner in the second windless state. Since the airflow blown out by the air conditioner in the first windless state can be more fully dispersed, the windless effect is more complete. By making the duration of a single cycle of operation of the air conditioner in the first windless state greater than or equal to the duration of operation of the air conditioner in the second windless state, it is possible to improve the uneven temperature distribution between near and far parts of the air conditioner while more fully ensuring the windless effect and more effectively avoiding discomfort caused by the blown airflow.

[0092] According to some embodiments of the present invention, in the windless mode, the air conditioner is controlled to first enter a first windless state. The duration of the first cycle of the air conditioner operating in the first windless state is a first preset duration, and the duration of the Nth cycle of the air conditioner operating in the first windless state is a second preset duration, where N≥2 and is an integer, and the second preset duration is less than the first preset duration. By having the air conditioner enter the first windless state first, a sufficient windless effect can be guaranteed when the air conditioner enters the windless mode. By making the first preset duration larger, the uneven temperature distribution between near and far locations of the air conditioner can be improved while ensuring a more sufficient windless effect, and discomfort caused by the blown air can be avoided more effectively. By making the second preset duration less than the first preset duration, the air conditioner can avoid staying in the first windless state for too long when cycling between the first and second windless states, which would result in poor temperature regulation capability for distant locations, allowing the air conditioner to more effectively regulate temperature for both near and far locations.

[0093] According to some embodiments of the present invention, the first preset duration is 90 min to 180 min, and the second preset duration is 15 min to 45 min. For example, the first preset duration can be 90 min, 120 min, 150 min, 180 min, etc. By ensuring that the first preset duration is not less than 90 min, the uneven temperature distribution between near and far locations of the air conditioner can be improved while ensuring a more complete draft-free effect and avoiding discomfort caused by the blown airflow. By ensuring that the first preset duration does not exceed 180 min, the air conditioner can balance airflow to both near and far locations, preventing insufficient temperature regulation capacity for distant locations due to the air conditioner remaining in a draft-free state for too long. For example, the second preset duration can be 15 min, 20 min, 25 min, 30 min, 35 min, 40 min, 45 min, etc. By setting the second preset duration to no less than 15 minutes, the air conditioner can effectively avoid the discomfort caused by excessively fast airflow when cycling between the first and second windless states. By setting the second preset duration to no more than 45 minutes, the air conditioner can avoid staying in the first windless state for too long when cycling between the first and second windless states, which would result in poor temperature regulation capabilities for distant locations. This allows the air conditioner to more effectively regulate the temperature for both near and far locations.

[0094] According to some embodiments of the present invention, the duration of a single cycle of operation of the air conditioner in the second windless state is a third preset duration, which is less than the first preset duration. By making the third preset duration less than the first preset duration, the air conditioner can more effectively avoid discomfort caused by excessively fast airflow.

[0095] According to some embodiments of the present invention, the third preset duration is less than or equal to the second preset duration. By making the third preset duration less than or equal to the second preset duration, it is possible to improve the uneven temperature distribution between near and far parts of the air conditioner while more fully ensuring the windless effect and more fully avoiding discomfort caused by the blown airflow.

[0096] For example, the third preset duration can be the same as the second preset duration; or, for another example, the third preset duration can be less than the second preset duration.

[0097] According to some embodiments of the present invention, the third preset duration is 15 min to 45 min. For example, the third preset duration can be 15 min, 20 min, 25 min, 30 min, 35 min, 40 min, 45 min, etc. By ensuring that the third preset duration is not less than 15 min, the air conditioner can balance airflow to both near and far locations, avoiding the air conditioner remaining in the first windless state for too long when cycling between the first and second windless states, which would result in insufficient temperature regulation for distant locations. By ensuring that the third preset duration is not greater than 45 min, the air conditioner can avoid staying in the second windless state for too long when cycling between the first and second windless states, which would cause discomfort due to prolonged airflow.

[0098] Preferably, the third preset duration can be 30 minutes.

[0099] An air conditioner according to a second aspect embodiment of the present invention, referring to Figures 1-8 It includes: housing 10, heat exchanger assembly 20, fan assembly 30 and control module.

[0100] An air outlet 40 and an air inlet 11 are formed on the housing 10. An air outlet channel 50 is provided inside the housing 10. A heat exchanger assembly 20 is disposed inside the housing 10. A fan assembly 30 includes a fan 31 and is disposed inside the housing 10 and located between the air outlet channel 50 and the heat exchanger assembly 20. A control module is disposed inside the housing 10 and controls the air conditioner to operate according to the control method of the first aspect embodiment of the present invention.

[0101] For example, the air conditioner is a split-type floor-standing air conditioner, which includes an indoor unit 100 and an outdoor unit. The indoor unit 100 includes the aforementioned casing 10, heat exchanger assembly 20, and fan assembly 30, with the fan's rotation axis extending vertically. An air inlet 11 is formed on the rear side of the casing 10, and an air outlet 40 is formed on the front side of the casing 10. The air outlet 40 includes a first air outlet area 41 and a second air outlet area 42 arranged vertically. When the air conditioner is working, the fan 31 drives the airflow to enter the casing 10 through the air inlet 11. After exchanging heat with the heat exchanger assembly 20, the airflow enters the fan assembly 30, and finally, the fan 31 drives the airflow to leave the air conditioner through the air outlet 40.

[0102] For example, after the user puts the air conditioner into a windless state, the control module adjusts the air conditioner to enter the first windless state and maintain it for a first preset time, then adjusts the air conditioner to enter the second windless state and maintain it for a third preset time, then adjusts the air conditioner to enter the first windless state and maintain it for the second preset time, and then the air conditioner cycles between the first windless state and the second windless state, maintaining the second preset time when entering the first windless state and maintaining the third preset time when entering the second windless state.

[0103] According to an embodiment of the present invention, an air conditioner that includes a control module and controls the air conditioner to operate according to the control method of the first aspect of the present invention can switch between a low wind speed and a large air outlet area and a long air delivery distance, thereby avoiding direct airflow from the air conditioner while taking into account the air delivery to both near and far areas, and improving the uniformity of temperature distribution in the room.

[0104] The following reference Figures 1-8 A control method for an air conditioner according to some specific embodiments of the present invention is described.

[0105] According to a control method for an air conditioner based on a first aspect of the present invention, the air conditioner has an air outlet 40 and an air outlet duct 50 communicating with the air outlet 40.
