Description

Technical Field

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

[0002] The indoor unit of an air conditioner is an important component of the air conditioning system. Its main components include the evaporator, fan motor, electrical control components, throttling components, and casing. The primary function of the indoor unit is to deliver the cool (or hot) air generated by the evaporator into the room via the fan motor, thereby regulating the indoor temperature.

[0003] Currently, when the indoor unit of an air conditioner is operating in cooling mode, the dry, cold airflow, after heat exchange, is blown into the room from the air outlet. The air guide plate on the outside of the outlet, directly exposed to this dry, cold airflow, will be cooler than the room temperature. Meanwhile, the warm, humid airflow from inside the room comes into contact with the air guide plate, easily causing condensation to form. This phenomenon is more pronounced in the air conditioner's powerful cooling mode, where the condensation may even drip, significantly impacting the user experience.

[0004] Therefore, it is necessary to improve the existing air supply structure of the indoor unit to reduce or eliminate condensation on the air guide plate during the use of the air conditioner and improve the user experience. Summary of the Invention

[0005] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide an auxiliary air supply structure that can reduce the temperature difference between the airflow blown out of the air outlet of the indoor air conditioner and the indoor air, improve the condensation phenomenon of the air guide plate, and help improve the user experience.

[0006] An auxiliary air supply structure includes an air supply body, which is disposed at the air outlet of the indoor unit of an air conditioner;

[0007] The air supply body is provided with an air duct, an air inlet and an air outlet. The air inlet and the air outlet are both connected to the air duct. The air outlet is set towards the air outlet of the indoor unit. A fan is provided at the air inlet.

[0008] This auxiliary air supply structure guides indoor air into the duct, allowing the warm, humid air inside the duct to exchange heat and pre-cool with the dry, cool air at the air outlet of the air conditioner. The lowered temperature and condensation within the duct create cooler, drier air. This cooler, drier air flows from the air outlet to the air vent, reducing the temperature difference between the airflow from the indoor unit and the indoor air, and also improving condensation on the air guide plate, thus enhancing the user experience.

[0009] In a preferred embodiment of the present invention, the air supply body is provided with an air cavity, and multiple partitions are provided inside the air cavity. One side of the partition is fixed to the inner wall of the air cavity, and the opposite side forms an air passage between the partition and the inner wall of the air cavity.

[0010] An air duct is formed between two adjacent partitions, and the air vents between two adjacent partitions are staggered in the vertical direction.

[0011] Multiple baffles form multiple air ducts within the air cavity, which helps to extend the airflow path within the air cavity, allowing the air to exchange heat more effectively and improving the heat exchange efficiency.

[0012] In a preferred embodiment of the present invention, the partition is set at an angle α with the horizontal plane, where 30°≤α≤45°.

[0013] The inclined baffles can prolong the airflow time in the duct and help to remove condensation in the duct.

[0014] In a preferred embodiment of the present invention, the partition is further provided with a water passage notch, which is located below the air passage.

[0015] The water inlet can discharge air condensation from the air duct.

[0016] In a preferred embodiment of the present invention, the air supply body is provided with a water inlet hole, the water inlet hole is connected to the bottom of the air duct, and a windproof protrusion is provided around the water inlet hole, the windproof protrusion protruding from one side of the water inlet hole along the axial direction of the water inlet hole; the diameter of the air inlet hole is larger than the diameter of the air outlet hole, and the diameter of the air outlet hole is larger than the diameter of the water inlet hole.

[0017] The water inlet is used to discharge the condensation in the air duct to the outside of the air duct, while the windproof protrusion can increase the resistance of the airflow in the air duct to discharge from the water inlet, ensuring that most of the airflow introduced from the left air inlet enters the air outlet of the indoor unit through the air outlet of the air duct.

[0018] The second objective of this invention is to provide an indoor unit, including an indoor unit body, an air outlet on the indoor unit body, and an auxiliary air supply structure as described above on one side of the air outlet.

[0019] In a preferred embodiment of the present invention, two auxiliary air supply structures are provided at the air outlet, and the two auxiliary air supply structures are located on opposite sides of the air outlet.

[0020] Two auxiliary air supply structures pre-cool the indoor air from the left and right sides of the air outlet, allowing more pre-cooled air to flow to the air outlet, which helps to improve the condensation phenomenon on the air guide plate.

[0021] A third objective of this invention is to provide an air conditioner, including an outdoor unit and an indoor unit as described above.

[0022] The fourth objective of this invention is to provide a control method for an air conditioner, implemented based on the indoor unit described above;

[0023] The control method includes the following steps:

[0024] Turn on the indoor unit to either cooling or heating mode;

[0025] Determine whether the difference between the indoor temperature and the preset temperature exceeds a threshold.

[0026] If yes, turn on the fan of the auxiliary air supply structure; if no, turn off the fan of the auxiliary air supply structure.

[0027] This method can prevent excessively cold or warm air from blowing directly on the human body, thus improving the user experience.

[0028] In a preferred embodiment of the present invention, an air guide plate and an air sweeping plate are provided at the air outlet of the indoor unit. The air guide plate is used to guide the airflow of the indoor unit in the up and down direction, and the air sweeping plate is used to sweep the airflow of the indoor unit in the left and right direction. Auxiliary air supply structures are provided on both the left and right sides of the air outlet of the indoor unit.

[0029] The control method further includes the following steps:

[0030] In cooling mode, the indoor unit activates left and right air swing mode;

[0031] Obtain the location of the indoor unit's air swing plate;

[0032] The fans in the auxiliary air supply structure that are close to the air sweeping plate run at the first speed, while the fans in the auxiliary air supply structure that are far away from the air guide plate run at the second speed.

[0033] The first speed is less than the second speed.

[0034] This method can prevent condensation from forming on the air swing plate of the indoor unit, thus providing users with a better user experience.

[0035] The beneficial effects of this invention are as follows:

[0036] This invention provides an auxiliary air supply structure, comprising an air supply body disposed at the air outlet of the indoor unit of an air conditioner. The air supply body includes an air duct, an air inlet, and an air outlet. Both the air inlet and outlet are connected to the air duct, and the outlet faces the air outlet of the indoor unit. A fan is located at the air inlet. When the air conditioner is in cooling mode, this auxiliary air supply structure draws indoor air into the air duct. The warm, humid air in the air duct exchanges heat with the dry, cold air at the air outlet, pre-cooling it. The temperature decreases, and condensation occurs within the air duct, resulting in cooler, drier air. This cooler, drier air flows from the air outlet to the air outlet, reducing the temperature difference between the airflow from the indoor unit and the indoor air, and improving condensation on the air guide plate, thus enhancing the user experience.

[0037] This application also provides an indoor unit, an air conditioner, and a control method for the air conditioner capable of performing the above-mentioned auxiliary air supply structure. The control method for the air conditioner can adjust the temperature of the airflow blown out of the air outlet of the air conditioner to prevent excessively cold or hot air from blowing directly on the human body, thereby improving the user experience. Moreover, the control method can improve the heat exchange efficiency of indoor air and help to increase the speed of indoor air conditioning. Attached Figure Description

[0047] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0048] The indoor unit of an air conditioner is an important component of the air conditioning system. Its main components include the evaporator, fan motor, electrical control components, throttling components, and casing. The primary function of the indoor unit is to deliver the cool (or hot) air generated by the evaporator into the room via the fan motor, thereby regulating the indoor temperature.

[0049] Currently, when the indoor unit of an air conditioner operates in cooling mode, the dry, cold airflow, after heat exchange, is blown into the room from the air outlet. The air guide plate outside the outlet, directly exposed to this dry, cold airflow, becomes cooler than the room temperature. Meanwhile, the warm, humid airflow from inside the room comes into contact with the air guide plate, easily causing condensation. This phenomenon is more pronounced in the air conditioner's powerful cooling mode, where the condensation can even drip, significantly impacting the user experience. Therefore, this application provides an auxiliary air supply structure.

[0050] Example 1

[0051] like Figures 1-5 As shown, this embodiment provides an auxiliary air supply structure, including an air supply body 1, which is disposed at the air outlet 110 of the indoor unit of the air conditioner.

[0052] The air supply body 1 is provided with an air duct 121, an air inlet 17 and an air outlet 11. The air inlet 17 and the air outlet 11 are both connected to the air duct 121. The air outlet 11 is set towards the air outlet 110 of the indoor unit. A fan 2 is provided at the air inlet 17.

[0053] Specifically, the fan 2 in this application can be a centrifugal fan 2 or an axial fan 2, mainly used to send outside air into the air duct 121 of the air supply body 1. Multiple air outlets 11 are provided, so that the air outlets 11 can deliver air to the air outlet 110 more quickly.

[0054] The air supply body 1 can be fixed to the air outlet 110 with screws. The outer shell of the air supply body 1 is made of a material with high heat exchange efficiency, or the outer shell of the air supply body 1 is made of thin plastic. In practical applications, both the outer shell of the air supply body 1 and the outer shell of the air conditioner indoor unit are made of plastic, so the air supply body 1 can be integrally injection molded with the outer shell of the air conditioner indoor unit. During use, the outdoor air mainly exchanges heat with the air at the air outlet 110 through the outer shell of the air supply body 1, that is, pre-cooling or preheating is achieved in the air supply body 1.

[0055] The air supply body 1 can be positioned at the left and right edges of the air outlet 110. In a more preferred embodiment, the air outlet 110 is disposed on the air conditioner casing, and the air supply body 1 can be close to the left and right edges of the air conditioner casing.

[0056] The auxiliary air supply structure is located at the air outlet 110 of the indoor unit. When the air conditioner is running in cooling mode, it guides indoor air into the air duct 121. The warm and humid air in the air duct 121 exchanges heat and pre-cools with the dry and cold air at the air outlet 110 of the air conditioner. The temperature decreases and condensation occurs in the air duct 121, turning it into slightly cooler and drier air. This slightly cooler and drier air flows from the air outlet 11 to the air outlet 110, which can reduce the temperature difference between the airflow blown out of the air outlet 110 of the indoor unit and the indoor air, and can also improve the condensation phenomenon on the air guide plate, thus helping to improve the user experience.

[0057] Example 2

[0058] like Figures 1-5 As shown, this embodiment includes the above-mentioned auxiliary air supply structure, which includes an air supply body 1, and the air supply body 1 is disposed at the air outlet 110 of the indoor unit of the air conditioner.

[0059] The air supply body 1 is provided with an air duct 121, an air inlet 17 and an air outlet 11. The air inlet 17 and the air outlet 11 are both connected to the air duct 121. The air outlet 11 is set towards the air outlet 110 of the indoor unit. A fan 2 is provided at the air inlet 17.

[0060] In this embodiment, the air supply body 1 is provided with an air cavity 15, and a plurality of partitions 12 are provided inside the air cavity 15. One side of the partition 12 is fixed to the inner wall of the air cavity 15, and the opposite side forms an air passage 13 between the partition and the inner wall of the air cavity 15.

[0061] An air duct 121 is formed between two adjacent partitions 12, and the air outlets 13 between two adjacent partitions 12 are staggered in the vertical direction.

[0062] The outer wall of the air cavity 15 is made of a heat-conducting material to improve the heat exchange efficiency between the air inside the air cavity 15 and the air at the air outlet 110.

[0063] Multiple baffles 12 form multiple air ducts 121 within the air cavity 15, which helps to extend the airflow path within the air cavity 15, enabling the air to exchange heat more effectively and improving the heat exchange efficiency.

[0064] Example 3

[0065] like Figures 1-5 As shown, this embodiment includes the above-mentioned auxiliary air supply structure, which includes an air supply body 1, and the air supply body 1 is disposed at the air outlet 110 of the indoor unit of the air conditioner.

[0066] The air supply body 1 is provided with an air duct 121, an air inlet 17 and an air outlet 11. The air inlet 17 and the air outlet 11 are both connected to the air duct 121. The air outlet 11 is set towards the air outlet 110 of the indoor unit. A fan 2 is provided at the air inlet 17.

[0067] In an embodiment, the air supply body 1 is provided with an air cavity 15, and multiple partitions 12 are provided inside the air cavity 15. One side of the partition 12 is fixed to the inner wall of the air cavity 15, and the opposite side forms an air passage 13 between the partition and the inner wall of the air cavity 15.

[0068] An air duct 121 is formed between two adjacent partitions 12, and the air outlets 13 between two adjacent partitions 12 are staggered in the vertical direction.

[0069] In this embodiment, the partition 12 is set at an angle α with the horizontal plane, where 30°≤α≤45°.

[0070] The inclined baffle 12 can prolong the airflow time in the air duct 121 and help to remove condensation in the air duct 121.

[0071] The inclined baffle 12 can make the most of the space inside the air cavity 15, so that the distance of the air duct 121 in the air cavity 15 is the longest, and the air can exchange heat with the air at the air outlet 110 for a longer period of time in the air duct 121.

[0072] The air ducts 121 formed between the partitions 12 are arranged in a serpentine pattern within the air cavity 15.

[0073] Example 4

[0074] like Figures 1-5 As shown, this embodiment includes the above-mentioned auxiliary air supply structure, which includes an air supply body 1, and the air supply body 1 is disposed at the air outlet 110 of the indoor unit of the air conditioner.

[0075] The air supply body 1 is provided with an air duct 121, an air inlet 17 and an air outlet 11. The air inlet 17 and the air outlet 11 are both connected to the air duct 121. The air outlet 11 is set towards the air outlet 110 of the indoor unit. A fan 2 is provided at the air inlet 17.

[0076] The air supply body 1 is provided with an air cavity 15, and multiple partitions 12 are provided inside the air cavity 15. One side of the partition 12 is fixed to the inner wall of the air cavity 15, and the opposite side forms an air passage 13 between the partition and the inner wall of the air cavity 15.

[0077] An air duct 121 is formed between two adjacent partitions 12, and the air outlets 13 between two adjacent partitions 12 are staggered in the vertical direction.

[0078] The partition 12 is set at an angle α to the horizontal plane, where 30°≤α≤45°.

[0079] In this embodiment, the partition 12 is also provided with a water passage notch 14, which is located below the air passage 13.

[0080] Specifically, the water inlet 14 and the air outlet 13 correspond to each other. That is, in a partition 12, there are opposing first and second sides. The air outlet 13 is located on the first side closer to the partition 12, and the water inlet 14 is located on the second side of the partition 12. The water inlet 14 can discharge air condensation in the air duct 121.

[0081] Example 5

[0082] like Figures 1-5 As shown, this embodiment includes the above-mentioned auxiliary air supply structure, which includes an air supply body 1, and the air supply body 1 is disposed at the air outlet 110 of the indoor unit of the air conditioner.

[0083] The air supply body 1 is provided with an air duct 121, an air inlet 17 and an air outlet 11. The air inlet 17 and the air outlet 11 are both connected to the air duct 121. The air outlet 11 is set towards the air outlet 110 of the indoor unit. A fan 2 is provided at the air inlet 17.

[0084] The air supply body 1 is provided with an air cavity 15, and multiple partitions 12 are provided inside the air cavity 15. One side of the partition 12 is fixed to the inner wall of the air cavity 15, and the opposite side forms an air passage 13 between the partition and the inner wall of the air cavity 15.

[0085] An air duct 121 is formed between two adjacent partitions 12, and the air outlets 13 between two adjacent partitions 12 are staggered in the vertical direction.

[0086] The partition 12 is set at an angle α to the horizontal plane, where 30°≤α≤45°.

[0087] The partition 12 is also provided with a water passage notch 14, which is located below the air passage 13.

[0088] In this embodiment, the air supply body 1 is provided with a water inlet hole 16, which is connected to the bottom of the air duct 121. A windproof protrusion 3 is provided around the water inlet hole 16, which protrudes from one side of the water inlet hole 16 along the axial direction of the water inlet hole 16. The diameter of the air inlet hole 17 is larger than the diameter of the air outlet hole 11, and the diameter of the air outlet hole 11 is larger than the diameter of the water inlet hole 16.

[0089] The water inlet 16 is used to discharge the condensation in the air duct 121 to the outside of the air duct 121, while the windproof protrusion 3 can increase the resistance of the airflow in the air duct 121 to be discharged from the water inlet 16, ensuring that most of the airflow introduced from the left air inlet enters the air outlet 110 of the indoor unit through the air outlet 11 of the air duct 121.

[0090] More specifically, the windproof protrusion 3 is a semi-circular plate fixed to one side of the water inlet hole 16. In a preferred embodiment, the diameter of the air inlet hole 17 is larger than the diameter of the air outlet hole 11, and the diameter of the air outlet hole 11 is larger than the diameter of the water inlet hole 16.

[0091] The diameter of the air inlet 17 is larger than that of the air outlet 11, which facilitates the fan 2 to introduce indoor air into the air duct 121. The diameter of the water inlet 16 is smaller, and together with the function of the windproof protrusion 3, most of the airflow introduced by the air inlet 17 enters the air outlet 110 of the indoor unit through the air outlet 11 of the air duct 121.

[0092] Furthermore, the water inlet 16 is located at the lowest point of the air duct 121, allowing condensation inside the air duct 121 to be discharged directly through the water inlet 16 under the influence of gravity. In practical applications, a water pipe can be connected to the water inlet 16 to discharge the condensation in the air duct 121 to a designated location, such as the drip tray of an air conditioner.

[0093] Example 6

[0094] This embodiment provides an indoor unit, which includes an indoor unit body 100, an air outlet 110 is provided on the indoor unit body 100, and an auxiliary air supply structure as described above is provided on one side of the air outlet 110.

[0095] The indoor unit body 100 includes a bottom shell, and an air outlet 110 is disposed at the bottom shell. The auxiliary air supply structure is disposed at the air outlet 110, and the auxiliary air supply structure includes an air supply body 1, which is disposed at the air outlet 110 of the indoor unit of the air conditioner.

[0096] The air supply body 1 is provided with an air duct 121, an air inlet 17 and an air outlet 11. The air inlet 17 and the air outlet 11 are both connected to the air duct 121. The air outlet 11 is set towards the air outlet 110 of the indoor unit. A fan 2 is provided at the air inlet 17.

[0097] The air supply body 1 is provided with an air cavity 15, and multiple partitions 12 are provided inside the air cavity 15. One side of the partition 12 is fixed to the inner wall of the air cavity 15, and the opposite side forms an air passage 13 between the partition and the inner wall of the air cavity 15.

[0098] An air duct 121 is formed between two adjacent partitions 12, and the air outlets 13 between two adjacent partitions 12 are staggered in the vertical direction.

[0099] The partition 12 is set at an angle α to the horizontal plane, where 30°≤α≤45°.

[0100] The partition 12 is also provided with a water passage notch 14, which is located below the air passage 13.

[0101] The air supply body 1 is provided with a water inlet hole 16, which is connected to the bottom of the air duct 121. A windproof protrusion 3 is provided around the water inlet hole 16, which protrudes from one side of the water inlet hole 16 along the axial direction of the water inlet hole 16. The diameter of the air inlet hole 17 is larger than the diameter of the air outlet hole 11, and the diameter of the air outlet hole 11 is larger than the diameter of the water inlet hole 16.

[0102] In a preferred embodiment, two auxiliary air supply structures are provided at the air outlet 110, and the two auxiliary air supply structures are located on opposite sides of the air outlet 110.

[0103] Two auxiliary air supply structures pre-cool the indoor air from the left and right sides of the air outlet 110, so that more pre-cooled air flows to the air outlet 110, which helps to improve the condensation phenomenon of the air guide plate.

[0104] Example 7

[0105] This embodiment provides an air conditioner, including an outdoor unit and an indoor unit as described above. The bottom casing of the indoor unit has an air outlet 110, and two auxiliary air supply structures are provided at the air outlet 110, located on opposite sides of the air outlet 110.

[0106] The auxiliary air supply structure is set at the air outlet 110. The auxiliary air supply structure includes an air supply body 1, which is set at the air outlet 110 of the indoor unit of the air conditioner.

[0107] The air supply body 1 is provided with an air duct 121, an air inlet 17 and an air outlet 11. The air inlet 17 and the air outlet 11 are both connected to the air duct 121. The air outlet 11 is set towards the air outlet 110 of the indoor unit. A fan 2 is provided at the air inlet 17.

[0108] The air supply body 1 is provided with an air cavity 15, and multiple partitions 12 are provided inside the air cavity 15. One side of the partition 12 is fixed to the inner wall of the air cavity 15, and the opposite side forms an air passage 13 between the partition and the inner wall of the air cavity 15.

[0109] An air duct 121 is formed between two adjacent partitions 12, and the air outlets 13 between two adjacent partitions 12 are staggered in the vertical direction.

[0110] Two auxiliary air supply structures pre-cool the indoor air from the left and right sides of the air outlet 110, so that more pre-cooled air flows to the air outlet 110, which helps to improve the condensation phenomenon of the air guide plate.

[0111] Example 8

[0112] like Figure 6 As shown, this embodiment provides a control method for an air conditioner, implemented based on the indoor unit described above. An air guide plate is provided at the air outlet 110 of the indoor unit, and the air guide plate is used to guide the airflow upward and downward of the indoor unit.

[0113] Specifically, the indoor unit is also equipped with a drive mechanism that drives the air guide plate.

[0114] The control method includes the following steps:

[0115] S100, turn on the indoor unit's cooling or heating mode;

[0116] S200. Determine whether the difference between the indoor temperature and the preset temperature exceeds a threshold; the threshold can be 3 degrees Celsius. S300. If yes, turn on the fan 2 of the auxiliary air supply structure; if no, turn off the fan 2 of the auxiliary air supply structure.

[0117] This method can prevent excessively cold or warm air from blowing directly on the human body, thus improving the user experience.

[0118] The following describes the control method of the air conditioner in this embodiment in detail, taking a preset temperature of 25°C as an example:

[0119] When the indoor unit starts in cooling or heating mode, the cooling or heating mode can be either strong cooling or strong heating.

[0120] The fan 2 is controlled to run at its maximum speed N, maximizing the airflow through the duct 121. The airflow in the duct 121 exchanges heat with the airflow at the outlet 110 before flowing from the outlet hole 11 to the outlet 110. This effectively reduces the temperature difference between the air near the auxiliary air supply structure and the indoor air. Furthermore, the airflow from the auxiliary air supply structure partially cancels out the airflow from the outlet 110, preventing excessively cold or warm air from blowing directly on the body. When the indoor temperature approaches the set temperature (temperature difference less than 3 degrees Celsius), the fan 2 is stopped.

[0121] Example 9

[0122] like Figures 6-7 As shown, this embodiment provides a control method for an air conditioner, implemented based on the indoor unit described above. An air guide plate is provided at the air outlet 110 of the indoor unit, which is used to guide the airflow of the indoor unit vertically. An air sweeping plate is also provided at the air outlet 110 of the indoor unit, which is used to sweep the airflow of the indoor unit horizontally.

[0123] In this embodiment, auxiliary air supply structures are provided on both the left and right sides of the air outlet 110 of the indoor unit;

[0124] The control method further includes the following steps:

[0125] In cooling mode, the indoor unit activates left and right air swing mode;

[0126] S10. Obtain the location of the indoor unit's air swing plate;

[0127] S20. The fan 2 of the auxiliary air supply structure close to the air sweeping plate runs at a first speed, and the fan 2 of the auxiliary air supply structure far away from the air sweeping plate runs at a second speed.

[0128] The first speed is less than the second speed.

[0129] This method can prevent condensation from forming on the left and right air swing plates of the indoor unit, thus providing users with a better user experience.

[0130] The control method described in this implementation can be used for four-way air-sweeping indoor units. The second speed can be the maximum speed of fan 2, denoted by N.

[0131] When the four-sided air-sweeping indoor unit is running in cooling mode, when the left and right air-sweeping vanes are positioned slightly to the left of the air outlet 110, the left auxiliary air supply structure is controlled to operate at half its maximum speed (0.5*N), and the right auxiliary air supply structure is controlled to operate at half its maximum speed (N). This ensures that the airflow temperature on the right side of the air outlet 110 is close to the indoor temperature, preventing condensation on the right side of the air guide vanes and improving the user experience. When the left and right air-sweeping vanes are positioned slightly to the right, the right auxiliary air supply structure is controlled to operate at half its maximum speed (0.5*N), and the left auxiliary air supply structure is controlled to operate at half its maximum speed (N). This ensures that the airflow temperature on the left side of the air outlet 110 is close to the indoor temperature, preventing condensation on the left side of the air guide vanes and improving the user experience.

[0132] In this embodiment, it can be implemented together with the air conditioner control method in Embodiment 8. That is, in one indoor unit, the operation of the indoor unit is controlled simultaneously in the following two ways. Specifically:

[0133] S100, turn on the indoor unit's cooling or heating mode;

[0134] S200: Determine whether the difference between the indoor temperature and the preset temperature exceeds a threshold; the threshold can be 3 degrees Celsius.

[0135] S300 If yes, then turn on the fan 2 of the auxiliary air supply structure; otherwise, turn off the fan 2 of the auxiliary air supply structure.

[0136] In cooling mode, the indoor unit activates left and right air swing mode;

[0137] S10. Obtain the location of the indoor unit's air swing plate;

[0138] S20. The fan 2 of the auxiliary air supply structure close to the air sweeping plate runs at a first speed, and the fan 2 of the auxiliary air supply structure far away from the air sweeping plate runs at a second speed.

[0139] The first speed is less than the second speed.

[0140] Additionally, it should be noted that the drive mechanisms for the indoor unit's control air guide plate and the air sweeping plate are different.

[0141] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0142] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0143] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
