[0042] The following describes a method for controlling the air conditioner 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0043] Reference Figure 1-Figure 6 As shown, the air conditioner 100 according to the embodiment of the present invention is operated by the control method of the air conditioner 100 according to the embodiment of the present invention, and the air conditioner 100 according to the embodiment of the present invention may include: a housing 10 and an air guide plate 20. For example, the air conditioner 100 may be a wall mounted air conditioner 100.

[0044] Specifically, the shell 10 has an air outlet 11, and the air guide plate 20 is rotatably arranged at the air outlet 11, so that the air guide plate 20 can be used to open or close the air outlet 11 to achieve different usage requirements, and the angle of the air guide plate 20 can be adjusted according to the needs of the user to achieve the wind guiding effect on the blown airflow.

[0045] In addition, if Figure 1-Figure 9 As shown, the air guide plate 20 is provided with a plurality of (greater than or equal to two) air dispersion holes 21 arranged at intervals, and the air conditioner 100 has a windless mode. When the air conditioner 100 is in the windless mode, the airflow flowing out of the air outlet 11 can be dispersed through the air dispersion holes 21, avoiding problems such as poor comfort caused by strong direct airflow, so that the user's comfort is good and the user's experience is improved. For example, the air conditioner 100 can realize a cooling windless mode and a heating windless mode.

[0046] In some embodiments, Figure 3-Figure 6 , Figure 8 As shown, the air conditioner 100 further includes a louver 43, which is rotatably disposed on a side of the air guide plate 20 facing the inside of the air conditioner 100, and there are a plurality of louvers 43, which are arranged along the length direction of the air guide plate 20 (for example, Figure 8 The plurality of louvers 43 are arranged at intervals (in the left and right directions shown in the figure), and the airflow from the air outlet 11 can be guided and the direction of the airflow can be adjusted. The air supply range of the air conditioner 100 can be increased, thereby improving the user experience.

[0047] In the embodiment of the present invention, the number of the louvers 43 can be flexibly set according to actual conditions. For example, the louvers 43 can be as follows: Figure 8 Ten are shown, but there may be two, three, four, five, six, seven, eight, nine, eleven or more, all of which are within the scope of protection of the present invention.

[0048] It should be noted that, for the convenience of description, the directions such as "left and right directions" in the present invention are based on the directions shown in the drawings, but are not limitations on the directions in actual application.

[0049] In some embodiments, Fig.10 As shown, the louver 43 includes a mounting portion 432, and the air guide plate 20 has a mounting hole 24. There are multiple mounting holes 24 corresponding to the louver 43 one by one, and the multiple mounting holes 24 are arranged at intervals along the length direction of the air guide plate 20. The mounting portion 432 cooperates with the mounting holes 24 to install the louver 43 on the air guide plate 20 to ensure that the louver 43 is reliably fixed on the air guide plate 20.

[0050] In addition, if Figure 8 and Fig.10 As shown, the louver 43 includes an air guide portion 431 and a connecting portion 433, the connecting portion 433 is spaced apart from the mounting portion 432, and the air conditioner 100 further includes a connecting rod 44, the connecting rod 44 extends along the length direction of the air guide plate 20, and the connecting rod 44 is rotatably connected to the connecting portion 433. Thus, by driving the connecting rod 44 to move along the length direction of the air guide plate 20, the connecting rod 44 can drive the connecting portion 433 to move, and the angle of the air guide portion 431 can be adjusted, so that the air guide portion 431 can play a role in guiding the air, adjusting the flow direction of the airflow, and achieving different air supply ranges.

[0051] In some embodiments, the air conditioner 100 includes a driving assembly, which is disposed on the side of the air guide plate 20 facing the interior of the air conditioner 100, and the driving assembly is connected to the connecting rod 44, so that the driving assembly can drive the connecting rod 44 to move along the length direction of the air guide plate 20 to drive the louver 43 to rotate, thereby realizing the swing requirement of the louver 43 and improving the air guiding effect of the louver 43.

[0052] It can be understood that by driving the connecting rod 44 to move along the length direction of the air guide plate 20 through the driving component, one end of the connecting portion 433 can be driven to swing along the length direction of the air guide plate 20, and one end of the mounting portion 432 is fixed on the air guide plate 20, so that the louver 43 can be swung along the length direction of the air guide plate 20, and the direction of the airflow can be adjusted according to the different needs of the users.

[0053] In some embodiments of the present invention, Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig.10 As shown, the air guide plate 20 includes a first air guide plate 201 and a second air guide plate 202 which are stacked, the louver 43 is rotatably arranged on the first air guide plate 201, and the second air guide plate 202 is provided with a plurality of air dispersion holes 21 which are spaced apart, so that the louver 43 can be installed on the second air guide plate 202 through the first air guide plate 201, and the second air guide plate 202 can provide a good supporting effect on the first air guide plate 201, thereby ensuring that the louver 43 is reliably fixed on the air guide plate 20.

[0054] In addition, if Figure 3-Figure 10 As shown, in the length direction perpendicular to the air guide plate 20, the middle parts of the cross sections of the first air guide plate 201 and the second air guide plate 202 both protrude in the direction away from the louver 43, and the first air guide plate 201 and the second air guide plate 202 are both formed as smooth arc-shaped plates, so that the air guide plate 20 can control the air supply angle of the air flow out of the air outlet 11 to avoid the outflowing gas from blowing directly onto the ceiling, thereby allowing the air flow to flow farther and expanding the coverage of the air flow, and by adjusting the angle of the air guide plate 20, the air flow out of the air outlet 11 can be controlled to flow close to the wall, reducing the air flow blowing directly onto the user and improving the user's comfort.

[0055] In some embodiments, the first air guide plate 201 is snap-connected with the second air guide plate 202, which is convenient to process, simple to assemble, and easy to disassemble, so that the air guide plate 20 can be easily cleaned, repaired, and replaced.

[0056] According to some embodiments of the present invention, Figure 8 and Fig.10 As shown, the first air guide plate 201 has an avoidance hole 25, the cross-sectional area of ​​the avoidance hole 25 is larger than the cross-sectional area of ​​the air dispersion hole 21, and the avoidance hole 25 is provided in the flow direction of the airflow (for example Figure 5 In the direction indicated by the middle arrow), the first air guide plate 201 is located upstream of the second air guide plate 202. The design of the avoidance hole 25 can avoid the wind dispersion hole 21 to prevent the first air guide plate 201 from blocking the airflow and reduce the air volume flowing to the wind dispersion hole 21, so that the airflow can pass through the avoidance hole 25 and the wind dispersion hole 21 in turn, thereby reducing the wind pressure and achieving a windless design.

[0057] In some embodiments, Figure 8 and Fig. 9 As shown, the avoidance holes 25 can be multiple (greater than or equal to two) spaced apart, and the portion of the first air guide plate 201 other than the avoidance holes 25 can play a role in strengthening the structural strength of the air guide plate 20 and ensuring the stability and reliability of the first air guide plate 201.

[0058] In some embodiments of the present invention, Fig. 9 As shown, a swirl structure 211 is provided in the air dispersion hole 21, and the swirl structure 211 is used to drive the airflow passing through the air dispersion hole 21 to rotate, so as to prevent the airflow from directly flowing out of the air dispersion hole 21, thereby ensuring the reliability of the air dispersion hole 21 in reducing the wind pressure and wind speed, further reducing the wind pressure and wind speed of the airflow in the air dispersion hole 21, ensuring the effectiveness of the windless feeling, and improving the user experience.

[0059] In some embodiments, reference Fig. 9 As shown, the swirl structure 211 includes a central portion 212 and a swirl portion 213. The central portion 212 is disposed in the air dispersion hole 21, and the central portion 212 is spaced apart from the inner peripheral wall of the air dispersion hole 21. The swirl portions 213 are multiple and spaced apart along the circumferential direction of the central portion 212. One end of the swirl portion 213 is connected to the central portion 212, and the other end of the swirl portion 213 is connected to the inner peripheral wall of the air dispersion hole 21. The air dispersion hole 21 can be divided into multiple spaced-apart sub-air dispersion holes 214, thereby ensuring the structural strength of the swirl structure 211 and improving the reliability of the air dispersion hole 21.

[0060] In addition, if Fig. 9 As shown, along the circumferential direction of the air dispersion hole 21, the surface of the swirl portion 213 facing the inside of the air conditioner 100 is a swirl surface, and in the direction from the first air guide plate 201 to the second air guide plate 202, the swirl surface is inclined toward the outside of the air conditioner 100, and the swirl surface can play a guiding role, and can divide the airflow into multiple parts after the airflow flows into the air dispersion hole 21, and the airflow of each part flows into a sub-air dispersion hole 214, and the airflow in each sub-air dispersion hole 214 is blown out along the inclined direction of the corresponding swirl surface. Since the inclined directions of the multiple swirl surfaces in the same air dispersion hole 21 are different, the airflow directions in the multiple sub-air dispersion holes 214 are different, so that the airflow in each air dispersion hole 21 can be secondary dispersed by the swirl structure 211, and the airflow direction in each sub-air dispersion hole 214 can be changed, thereby further reducing the wind pressure and wind speed of the airflow flowing out of the air dispersion hole 21, thereby improving the effect of no wind feeling, and improving the user experience.

[0061] In the embodiment of the present invention, the number of the swirl parts 213 can be flexibly set according to actual conditions. For example, the swirl parts 213 can be as follows: Fig. 9Four are shown, but there may be two, three, five, six or more, all of which are within the protection scope of the present invention.

[0062] In a specific embodiment, Fig. 9 As shown, each air dispersion hole 21 is provided with a swirl structure 211, and the swirl structure 211 includes a central portion 212 and four swirl portions 213. The four swirl portions 213 are respectively located on both sides of the central portion 212 along the length direction of the air guide plate 20 and on both sides along the width direction of the air guide plate 20. The two swirl portions 213 located on both sides of the central portion 212 along the length direction of the air guide plate 20 are arranged opposite to each other and extend along the length direction of the air guide plate 20. The two swirl portions 213 located on both sides of the central portion 212 along the width direction of the air guide plate 20 are arranged opposite to each other and extend along the length direction of the air guide plate 20. The flow portions 213 are relatively arranged and extend along the width direction of the air guide plate 20, so as to divide the air dispersion hole 21 into four sub-air dispersion holes 214. The inclination directions of the four swirl surfaces are all different, and the airflow flowing into the air dispersion hole 21 can be divided into four parts and flow into the four sub-air dispersion holes 214 respectively. Under the guidance of the swirl surfaces of the four swirl portions 213, the flow directions of the airflow in the four sub-air dispersion holes 214 are changed, the wind pressure and wind speed of the airflow flowing out of the air dispersion hole 21 are reduced, the effect of no wind feeling is improved, and the user experience is improved.

[0063] In some embodiments, Fig. 9 As shown, the rotation directions of the swirl structures 211 in any two adjacent air dispersion holes 21 are opposite, and the arrangement modes of the corresponding inclination directions of the swirl surfaces are also different, which can avoid the airflows in the two adjacent air dispersion holes 21 from flowing in the same direction, thereby avoiding the two airflows flowing out of the two adjacent air dispersion holes 21 from converging into one, increasing the wind pressure and air volume of a single airflow, and further avoiding the convergence of multiple airflows, thereby ensuring the effect of no wind feeling and improving the user experience.

[0064] In some specific embodiments, Fig. 9 and Fig.10 As shown, the air diffusion holes 21 are arranged in multiple rows and columns, wherein the multiple air diffusion holes 21 in the same row are arranged in the length direction of the second air guide plate 202 (for example Figure 8 The plurality of air dispersion holes 21 located in the same column are spaced apart in the width direction of the second air guide plate 202, the rotation directions of the swirl structures 211 in any two adjacent air dispersion holes 21 located in the same row are opposite, and the rotation directions of the swirl structures 211 in any two adjacent air dispersion holes 21 located in the same column are also opposite, thereby ensuring that the rotation directions of the swirl structures 211 in any two adjacent air dispersion holes 21 are opposite.

[0065] According to some embodiments of the present invention, Figure 3 , Figure 4 and Figure 6As shown, the air conditioner 100 further includes a heat exchange component 41 and a fan 42, both of which are arranged in the housing 10. The airflow in the housing 10 can first exchange heat with the heat exchange component 41, and the airflow after heat exchange can be driven by the fan 42 to blow into the room through the air outlet 11, thereby achieving the purpose of adjusting the indoor temperature and meeting the user's use needs. For example, the fan 42 can be a crossflow impeller.

[0066] In some embodiments, Figure 1 As shown, the air conditioner 100 may include a temperature detection device 30, which is disposed on the housing 10. The temperature detection device 30 can detect the indoor temperature and obtain the indoor temperature, so that the air conditioner 100 can be intelligently controlled according to different indoor temperatures to improve the user experience. For example, the temperature detection device 30 may be an infrared smart eye temperature detection device.

[0067] In some embodiments, Figure 3 , Figure 4 and Figure 6 As shown, the air conditioner 100 also includes a base plate 12, and the shell 10 is detachably connected to the base plate 12. The base plate 12 is fixed to the wall, which can realize the positioning and fixation of the air conditioner 100, ensure the reliability of the fixation of the air conditioner 100, and realize the fixation requirement of the air conditioner 100 on the wall.

[0068] In addition, if Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the side of the housing 10 away from the bottom plate 12 (eg Figure 3 A panel 13 is provided on the front side (as shown in the figure), and a temperature detection device 30 is provided on the panel 13, so that the detection range of the temperature detection device 30 is larger, which makes it easier for the temperature detection device 30 to detect the indoor temperature and realize the demand for temperature detection of the floor and ceiling.

[0069] In the related art, when the air conditioner is in heating mode, the strong airflow of hot air can be prevented from blowing directly on the user by setting the air conditioner in windless mode. However, when the air conditioner is in windless mode, the hot air will be dispersed, making the upper and lower temperatures in the room higher, thereby causing more discomfort to the user.

[0070] Therefore, in the present invention, if Fig.11 As shown, the air conditioner 100 has a soft wind mode. The control method of the air conditioner 100 according to the embodiment of the present invention includes:

[0071] The air conditioner 100 operates in heating mode, that is, realizes the heating demand for indoor space, for example, the heating mode of the air conditioner 100 is realized by the heat exchange component 41;

[0072] Obtaining indoor temperatures T1, T2, and T3, where the indoor temperatures T1, T2, and T3 are respectively the temperatures of the upper layer, middle layer, and lower layer of the room. For example, the indoor temperatures T1, T2, and T3 can be obtained by a temperature detection device 30;

[0073] Determining that an instruction to enter the windless mode is received, for example, the user can adjust the mode of the air conditioner 100 through a remote controller, so that the air conditioner 100 can receive an instruction to enter the windless mode for cooling;

[0074] Determine whether the indoor temperature T1, T2, T3 is less than the set temperature;

[0075] If at least one of the indoor temperatures T1, T2, and T3 is lower than the set temperature, the air conditioner 100 is controlled to turn on the soft wind mode. In other words, when the indoor temperature is low or there is a temperature difference, the air conditioner 100 is controlled to turn on the soft wind mode, which can increase the indoor heating effect and improve the user's comfort.

[0076] If the indoor temperatures T1, T2, and T3 are all greater than or equal to the set temperature, the air conditioner 100 is controlled to turn on the windless mode, so that the airflow flowing out of the air outlet 11 can be dispersed through the air dispersion holes 21, avoiding problems such as poor comfort caused by strong direct airflow, thereby improving the user experience.

[0077] Thus, by judging the indoor temperatures T1, T2, and T3, the mode of the air conditioner 100 can be intelligently adjusted to realize the intelligence of the air conditioner 100. When the air conditioner 100 is in heating operation and receives an instruction to enter the windless mode, the above control method can avoid turning on the windless mode when the temperature in the room is low, and can reduce the temperature difference in the room, effectively reducing the stratified temperature difference in the height direction that is easily generated by directly turning on the windless mode, greatly improving the temperature uniformity, for example, it can avoid the phenomenon of cold floors and hot roofs in the room, thereby avoiding the problem of cold feet caused by the low temperature in the lower layer of the room, which is conducive to improving the user experience and the user's comfort. For example, the above control method can better maintain a comfortable environment with a temperature difference of less than 5° in the room.

[0078] It can be understood that the “upper layer, middle layer and lower layer of the room” are evenly divided in the height direction of the indoor space, and form the upper layer, middle layer and lower layer of the room respectively in the direction from top to bottom.

[0079] It should be noted that, here, "obtaining indoor temperatures T1, T2, T3" can be to continuously obtain the indoor temperatures or to obtain the indoor temperatures at set intervals. For example, the indoor temperatures T1, T2, T3 can be obtained once at set intervals (for example, 1 second, 2 seconds, 3 seconds).

[0080] In some embodiments, the specific value of the set temperature can be set according to actual conditions, for example, the set temperature can be set before leaving the factory or by the user, which can ensure the uniformity of the indoor temperature and meet the user's requirements for setting different temperatures. For example, the set temperature can be 26°C.

[0081] According to the control method of the air conditioner 100 of the embodiment of the present invention, the air conditioner 100 is operated for heating; the indoor temperatures T1, T2, and T3 are obtained; it is determined that an instruction to enter the windless mode is received; it is determined whether the indoor temperatures T1, T2, and T3 are less than the set temperature; if at least one of the indoor temperatures T1, T2, and T3 is less than the set temperature, the air conditioner 100 is controlled to turn on the soft wind mode; if the indoor temperatures T1, T2, and T3 are all greater than or equal to the set temperature, the air conditioner 100 is controlled to turn on the windless mode. In this way, it is possible to avoid turning on the windless mode when the temperature in the room is relatively low, and it is possible to reduce the temperature difference in the room, reduce the stratified temperature difference in the height direction that is easily generated by directly turning on the windless mode, improve the temperature uniformity, realize the intelligence of the air conditioner 100, and help improve the user experience and comfort of the user.

[0082] Since the control method of the air conditioner 100 according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the air conditioner 100 according to the embodiment of the present invention is operated by heating the air conditioner 100; obtaining the indoor temperatures T1, T2, and T3; determining that an instruction to enter the windless mode is received; judging whether the indoor temperatures T1, T2, and T3 are less than the set temperature; if at least one of the indoor temperatures T1, T2, and T3 is less than the set temperature, the air conditioner 100 is controlled to turn on the soft wind mode; if the indoor temperatures T1, T2, and T3 are all greater than or equal to the set temperature, the air conditioner 100 is controlled to turn on the windless mode. Thus, it is possible to avoid turning on the windless mode when the temperature in the room is relatively low, and to reduce the temperature difference in the room, reduce the stratified temperature difference in the height direction that is easily generated by directly turning on the windless mode, improve the temperature uniformity, realize the intelligence of the air conditioner 100, and help improve the user experience and comfort of the user.

[0083] In some embodiments of the present invention, Fig.11 As shown, if at least one of the indoor temperatures T1, T2, and T3 is lower than the set temperature, after the air conditioner 100 is controlled to turn on the soft wind mode, the control method includes:

[0084] Determine whether the indoor temperature T1, T2, T3 is less than the set temperature;

[0085] If the indoor temperatures T1, T2, and T3 are all greater than or equal to the set temperature, the air conditioner 100 is controlled to turn on the windless mode. In other words, the indoor temperatures T1, T2, and T3 all meet the requirements for controlling the air conditioner 100 to turn on the windless mode, which can avoid problems such as poor comfort caused by strong direct airflow and the problem of user discomfort caused by temperature differences in the room, thereby improving the user experience;

[0086] If so, the air conditioner 100 continues to be in the soft wind mode, which can continue to increase the heating effect on the room, avoiding the stratified temperature difference in the height direction that is easily generated by turning on the windless mode at this time. At the same time, the steps of determining whether the indoor temperatures T1, T2, and T3 are less than the set temperature are cyclically determined until the demand for controlling the air conditioner 100 to turn on the windless mode can be achieved, thereby meeting the user's usage needs.

[0087] According to some embodiments of the present invention, Figure 3 As shown, the two ends of the air outlet 11 in the width direction are respectively the first end 111 and the second end 112, and the second end 112 is located at the lower side of the first end 111. The two ends of the air guide plate 20 in the width direction are respectively the first air guide end 22 and the second air guide end 23, and the second air guide end 23 is located at the lower side of the first air guide end 22. In the windless mode, the air guide plate 20 closes the air outlet 11, so that the airflow flowing out of the air outlet 11 is dispersed through the air dispersion holes 21, avoiding problems such as poor comfort caused by strong direct airflow, thereby improving the comfort of users and enhancing the user experience.

[0088] In addition, if Figure 3 As shown, the distance between the first end 111 and the first air guide end 22 is S1, the distance between the second end 112 and the second air guide end 23 is S2, and S1=S2, which can ensure the normal rotation of the air guide plate 20, and in the windless mode, as much air as possible is dispersed through the air dispersion holes 21 and flows into the room, thereby improving the windless effect of the air conditioner 100, and the air flow can flow out through the gap between the first end 111 and the first air guide end 22 and the gap between the second end 112 and the second air guide end 23, thereby increasing the air output and ensuring the heating effect of the air conditioner 100.

[0089] In some embodiments of the present invention, Figure 4 and Figure 5As shown, the two ends of the air outlet 11 in the width direction are respectively the first end 111 and the second end 112, and the second end 112 is located at the lower side of the first end 111, and the two ends of the air guide plate 20 in the width direction are respectively the first air guide end 22 and the second air guide end 23, and the second air guide end 23 is located at the lower side of the first air guide end 22. In the soft wind mode, the second air guide end 23 rotates toward the outside of the air outlet 11 to open the air outlet 11 at the bottom, so that the air outlet 11 can form a semi-open and semi-closed state, the distance between the first end 111 and the first air guide end 22 is S3, the distance between the second end 112 and the second air guide end 23 is S4, and S3<S4.

[0090] As a result, a part of the airflow flowing out of the air outlet 11 can be dispersed through the air dispersion holes 21 and then flow into the room, avoiding the problem of strong airflow directly blowing on the user and causing poor comfort, and the other part of the airflow can flow out through the gap between the second end 112 and the second air guide end 23 to form a wall-attached hot air flow, reducing the speed of the hot air flow rising and dissipating, increasing the air output of the air conditioner 100, realizing single-flow soft air delivery, avoiding the problem of cold feet due to the low temperature in the lower floor of the room, reducing the temperature difference in the room, ensuring the heating effect of the air conditioner 100, and improving the user's experience.

[0091] In some embodiments, reference Figure 6 and Fig.11 As shown, the air conditioner 100 also has an air supply mode. After the air conditioner 100 is in heating operation and before it is determined that an instruction to enter the windless mode is received, the control method includes:

[0092] Controlling the air conditioner 100 to start the air supply mode can realize normal heating and air supply of the air conditioner 100, increase the indoor temperature, and meet the heating needs of the user.

[0093] According to some embodiments of the present invention, Figure 6 As shown, in the air supply mode, the second air guide end 23 rotates toward the outside of the air outlet 11 to open the air outlet 11 at the bottom, the distance between the first end 111 and the first air guide end 22 is S5, the distance between the second end 112 and the second air guide end 23 is S6, and S5<S6, S6>S4.

[0094] As a result, a large amount of airflow flowing out from the air outlet 11 can flow out between the second end 112 and the second air guide end 23, forming a large amount of wall-attached hot air flow, realizing floor heating-style wall-attached downward air supply, reducing the speed of the hot air flow rising and dissipating, ensuring the heating effect of the air conditioner 100, and improving the user experience.

[0095] In some embodiments of the present invention, Fig.11As shown, if at least one of the indoor temperatures T1, T2, and T3 is lower than the set temperature, controlling the air conditioner 100 to turn on the soft wind mode includes:

[0096] Controlling the air conditioner 100 to switch from the air supply mode to the soft wind mode can reduce the airflow flowing out between the second end 112 and the second air guide end 23, realize single-flow soft wind supply, avoid the problem of cold feet due to the low temperature in the lower floor of the room, ensure the heating effect of the air conditioner 100, make the user comfortable, and improve the user experience;

[0097] Controlling the rotation speed of the motor of the air conditioner 100 to remain constant can ensure the heating efficiency of the air conditioner 100 and the air volume of the air conditioner 100 to the room, thereby facilitating the increase of the indoor temperature and ensuring the comfort of the user.

[0098] According to some embodiments of the present invention, Fig.11 As shown, if the indoor temperatures T1, T2, and T3 are all greater than or equal to the set temperature, controlling the air conditioner 100 to turn on the windless mode includes:

[0099] Controlling the motor of the air conditioner 100 to run at a speed of N0 for a preset time can ensure the heating efficiency of the air conditioner 100 and the air volume of the air conditioner 100 to the room;

[0100] Controlling the rotation speed N0 to gradually decrease to N1, wherein N0>N1, can reduce the energy consumption of the air conditioner 100 and avoid problems such as directly reducing the rotation speed of the motor and causing the indoor temperature to drop, thereby ensuring the comfort of the user.

[0101] It can be understood that “controlling the rotation speed N0 to gradually decrease to N1” here can mean decreasing the rotation speed once at fixed time intervals (for example, 1 second, 2 seconds, 3 seconds) until it decreases to N1.

[0102] In some embodiments, the specific value of the preset time can be set according to actual conditions, for example, the preset time can be set before leaving the factory, which can reduce the energy consumption of the air conditioner 100 while ensuring the indoor temperature. For example, the preset time can be 20 minutes.

[0103] In some embodiments of the present invention, if the indoor temperatures T1, T2, and T3 are all greater than or equal to the set temperature, controlling the air conditioner 100 to turn on the windless mode includes:

[0104] Determine whether the indoor temperature T1, T2, T3 is greater than the preset temperature, and the preset temperature is greater than the set temperature;

[0105] If not, the motor of the air conditioner 100 is controlled to run at a speed of N0, which can ensure the heating efficiency of the air conditioner 100 and the air volume of the air conditioner 100 to the room;

[0106] If so, the speed N0 is controlled to gradually decrease to N1, wherein N0>N1. When the temperature requirement is met, the energy consumption of the air conditioner 100 can be reduced, and the problem of directly reducing the speed of the motor and causing the indoor temperature to drop can be avoided, thereby ensuring the comfort of the user.

[0107] In some embodiments, the specific value of the preset time can be set according to actual conditions. For example, the preset time can be set before leaving the factory to ensure the comfort of the user.

[0108] According to some embodiments of the present invention, Fig.11 As shown, if the indoor temperatures T1, T2, and T3 are all greater than or equal to the set temperature, after the air conditioner 100 is controlled to turn on the windless mode, the control method further includes:

[0109] Determine whether the indoor temperature T1, T2, T3 is less than the set temperature;

[0110] If at least one of the indoor temperatures T1, T2, and T3 is lower than the set temperature, the air conditioner 100 is controlled to switch from the no-wind mode to the soft-wind mode, so that the airflow outflowing from the air conditioner 100 can be increased, for example, the airflow outflowing between the second end 112 and the second air guide end 23 is increased, so as to realize single-flow soft wind supply, avoid the problem of cold feet due to the low temperature in the lower floor of the room, and ensure the heating effect of the air conditioner 100;

[0111] If the indoor temperatures T1, T2, and T3 are all greater than or equal to the set temperature, the air conditioner 100 continues to be in the windless mode. While meeting the indoor temperature requirements, it avoids problems such as strong airflow blowing directly on the user and causing poor comfort, thereby improving the user's comfort and enhancing the user's experience.

[0112] In some embodiments, Fig.11 As shown, the indoor temperatures T1, T2, and T3 are obtained at set intervals and the above control method is repeated. This can avoid the problem of the temperature in the room dropping or the large temperature difference in the room causing discomfort to the user, which is beneficial to improving the user experience and improving the user comfort.
