In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0049] Figure 1 is a schematic cross-sectional view of a terminal device for an air conditioner and an air conditioner according to an embodiment of the present invention, and is combined with Figure 2-8 The present invention provides a terminal device 1 for an air conditioner, comprising an air inlet pipe 11, a reel 15 and an air outlet curtain 12. The reel 15 is rotatably arranged. The air outlet curtain 12 is wound and connected to the reel 15. The air outlet curtain 12 has a connecting air passage 13 inside, and at least one surface of the air outlet curtain 12 is provided with one or more air outlet holes 14. The air outlet holes 14 are connected to the air inlet pipe 11 through the connecting air passage 13.

[0050] It should be noted that in Figure 1-3 In the figure, the position of the outdoor unit 5 is for illustration only and does not mean that the outdoor unit 5 is located on the upper side of the top wall. The outdoor unit 5 can be located at any position outdoors.

[0051] In this embodiment, the reel 15 can be arranged horizontally, and when rotating, the air curtain 12 can be unfolded downward under gravity, or the air curtain 12 can be unfolded upward under tension. The reel 15 can also be arranged vertically, and when rotating, the air curtain 12 can be unfolded to the left or right. Of course, the reel 15 can also be arranged obliquely, so that the air curtain 12 can be unfolded obliquely. The reel 15 can be provided with or connected to a driving device to realize forward and reverse rotation under the action of the driving device.

[0052] One end of the air curtain 12 is fixedly connected to the reel 15, and has a certain width and unfolded length, and its width and unfolded length are much greater than its thickness. When the reel 15 rotates, the other end of the air curtain 12 unfolds or reels relative to the reel 15. The air curtain 12 can be made of a flexible material as a whole to fit around the reel 15. The air curtain 12 can also be a combination of a rigid material and a flexible material, such as a bamboo curtain structure. The air curtain 12 can also be made of a rigid material as a whole, such as a drag chain structure. Usually, the air curtain 12 is rectangular as a whole. Of course, it can also be other shapes, such as wavy, oval, etc. It can be set according to the home decoration style, and there is no limitation here.

[0053] In this embodiment, at least one surface of the air curtain 12 is provided with one or more air outlet holes 14, and the air outlet holes 14 are connected to the air inlet pipe 11 through the connecting air passage 13 inside the air curtain 12. The air inlet pipe 11 is connected to the air outlet of the air conditioner. The air conditioner can be an integrated air conditioner without an air outlet panel, and the air outlet of the integrated air conditioner is connected to the air inlet pipe 11. The temperature-adjusting airflow generated by the integrated air conditioner enters the air curtain 12 of the terminal device 1 through the air inlet pipe 11, and then blows out through the air outlet holes 14. The air conditioner can also be a split air conditioner, in which the indoor unit is not provided with an air outlet panel, but the air inlet pipe 11 is connected to the air outlet of the indoor unit, and the temperature-adjusting airflow generated by the indoor unit enters the air curtain 12 of the terminal device 1 through the air inlet pipe 11, and then blows out through the air outlet holes 14. The air conditioner can also be a central air conditioning system, a fresh air system, etc., and the temperature-adjusting airflow or fresh airflow generated by it enters the air curtain 12 of the terminal device 1 through the air inlet pipe 11, and then blows out through the air outlet holes 14.

[0054] In this embodiment, there is no restriction on the length of the air inlet pipe 11. There can be one or more air inlet pipes 11. It should be noted that the air inlet pipe 11 described in this application is a feature of the use environment and a necessary technical feature of the terminal device 1 in actual use, rather than a necessary technical feature during production and sales. In other words, the terminal device 1 of the present invention only needs to be provided with a docking port connected to the air inlet pipe 11.

[0055] When in use, the air curtain 12 can be in two states, unfolded and retracted, by rotating the reel 15. In the unfolded state, the temperature-adjusting airflow or the fresh airflow can be blown out from the air outlet 14 to adjust the temperature or ventilate the room. In the retracted state, the air curtain 12 is retracted on the reel 15 and does not occupy the limited space in the room. Thus, the limited space in the room is reasonably utilized and the indoor beauty is improved.

[0056] In some embodiments of the terminal device of the present invention, Figure 1-5 As shown, there are a plurality of air outlet holes 14 , and the plurality of air outlet holes 14 are densely arranged on a surface of the air outlet curtain 12 according to a preset rule.

[0057] In this embodiment, there are multiple air outlets 14, and there can be one connecting air duct 13, and all air outlets 14 are connected to the connecting air duct 13. There can also be multiple connecting air ducts 13, and all air outlets 14 are distributed in groups to multiple connecting air ducts 13. Multiple air outlets 14 are densely arranged on the lower surface of the air outlet curtain 12, that is, the positions of the air outlets 14 are arranged according to the shape and size of the air outlet curtain 12. When the lower surface area of ​​the air outlet curtain 12 is large, the number of air outlets 14 is large, and the air outlet range is wide. It should be noted that when the air outlet curtain 12 is not fully unfolded, or in other words, when the unfolding degree is between 0% and 100%, only the air outlets 14 in the unfolded area can blow air outward. The air outlets 14 in the partial area of ​​the rolled-up state will be blocked when rolled up. In other words, as the air outlet curtain 12 is unfolded and rolled up, the number and position of the air outlets 14 can change, that is, the air outlet area and the air outlet range can change. In this way, the air outlet curtain 12 can be unfolded to a preset area as needed, thereby changing the air outlet area of ​​the air conditioner, enriching the temperature adjustment mode, and further improving the user experience.

[0058] In particular, when the air outlet holes 14 are evenly arranged along the unfolding direction of the air outlet curtain 12, the number of air outlet holes 14 that can blow air outward is proportional to the unfolding area or unfolding degree, that is, the air outlet area and air outlet range are proportional to the unfolding area or unfolding degree.

[0059] In this embodiment, the preset rules can be set according to factors such as temperature control requirements and aesthetic requirements. They can be simply arranged evenly or arranged according to a specific pattern, such as multiple circles, multiple rectangles, multiple five-pointed stars, central radiation, etc.

[0060] In particular, a decorative pattern or pattern may be provided on the outer surface of the air curtain 12, and the shape and position of the air outlet 14 may be arranged according to a preset rule to match the decorative pattern or pattern. For example, the decorative pattern is a starry sky map, and the air outlet 14 is arranged at the stars in the pattern, and the shape of the air outlet 14 is the shape of a star. In this way, the air conditioner and the home decoration style can be further unified, and a hidden and traceless installation effect can be achieved, thereby improving the beauty of the home decoration.

[0061] In some embodiments of the terminal device of the present invention, Figure 4-5 As shown, the thickness of the air curtain 12 is less than 3 cm. In this embodiment, the thickness of the air curtain 12 is the maximum thickness. The reel 15 is arranged horizontally. When the air curtain 12 is unfolded downward, in order to make the air volume of the air outlet holes 14 located at the upper and lower parts of the air curtain 12 consistent after the air curtain 12 is unfolded, the thickness of the air curtain 12 is usually set to gradually decrease from top to bottom, and the cross-sectional area of ​​the connecting air duct 13 at the upper part of the air curtain 12 is larger than the cross-sectional area of ​​the lower part. Of course, the thickness of the air curtain 12 can also be set to be consistent from top to bottom, so that it has a better appearance when unfolded.

[0062] On the other hand, the thicker the air curtain 12 is, the larger the cross-section of the connecting air channel 12 inside it can be set, which can increase the air volume without increasing the air velocity. However, the increase in thickness will also increase the space occupied when unfolding and retracting. The thickness of the air curtain 12 is less than 3 cm, which can minimize the space occupied by the terminal device.

[0063] In some embodiments of the terminal device of the present invention, Figure 1 , Figure 3 As shown, the air outlet holes 14 are long strip holes extending along the width direction of the air outlet curtain 12, and a plurality of air outlet holes 14 are evenly spaced along the unfolding direction of the air outlet curtain 12. On the one hand, the air outlet curtain can be made to discharge air more evenly, and on the other hand, the total area of ​​the air outlet holes 14 that discharge air can be proportional to the unfolding area or unfolding degree of the air outlet curtain 12, so as to facilitate accurate adjustment of the air outlet area or air volume.

[0064] In some embodiments of the terminal device of the present invention, Figure 2 As shown, the air outlet hole 14 is a round hole or a special-shaped hole. The round hole can improve the uniform air outlet effect of the air outlet curtain 12. The special-shaped hole can be a polygonal hole, an irregular hole, etc.

[0065] In particular, the outer surface of the air curtain 12 is provided with decorative graphics and patterns, and the decorative graphics and patterns have corresponding graphics, such as stars, moons, flowers, birds and insects, etc. The position of the special-shaped hole is located at the corresponding graphics, and the shape of the special-shaped hole is consistent with the corresponding graphics. In this way, the air conditioner can be further unified with the home decoration style, achieving a hidden and traceless installation effect, and improving the beauty of home decoration.

[0066] In some embodiments of the terminal device of the present invention, Figure 1-5 As shown, the reel 15 is configured to be rotatably disposed on a ceiling or a wall in the room.

[0067] In this embodiment, the reel 15 can be rotatably arranged on the top wall. When the reel 15 rotates, the air curtain 12 can be unfolded downward under the action of gravity, and the air outlet holes 14 on one or both surfaces of the air curtain 12 can blow air outward. The reel 15 can be rotatably arranged on a wall. When the reel 15 is arranged parallel to the wall, the air curtain 12 can be unfolded parallel to the wall, and the air outlet holes 14 on the surface of the air curtain 12 facing the room can blow air outward. In particular, decorative graphics and patterns can be arranged on the air curtain 12. In this case, the terminal device 1 can be used as a home decoration, and the air curtain 12 can be used as a wall panel or wallpaper. In this way, the unification of the air conditioner and the home decoration style can be further achieved, achieving a hidden and traceless installation effect, and improving the beauty of home decoration.

[0068] When the air conditioner is not in use, the reel 15 can be rotated to roll up the air curtain 12 onto the reel 15 on the top wall or the wall, thereby releasing limited indoor space.

[0069] In some embodiments of the terminal device of the present invention, Figure 4-5 As shown, the reel 15 is configured to be rotatably disposed on the top of a wall in the room, and the air curtain 12 is parallel to the wall.

[0070] In this embodiment, when the reel 15 rotates, the air curtain 12 can be unfolded downward under the action of gravity and unfolded parallel to the wall. This installation method can minimize the occupation of the limited indoor space when the air curtain 12 is unfolded. In particular, decorative graphics and patterns can be set on the air curtain 12. In this case, the terminal device 1 can be used as a home decoration, and the air curtain 12 can be used as a wall panel or wallpaper. In this way, the air conditioner can be further unified with the home decoration style, achieving a hidden and traceless installation effect, and improving the beauty of home decoration.

[0071] On the other hand, an air outlet hole 14 is provided on the side surface of the air outlet curtain 12 facing the room. When air is discharged from the air outlet hole 14, the air outlet curtain 12 will swing backward under the reaction of the air flow. In this embodiment, the wall behind the air outlet curtain 12 can support the air outlet curtain 12 to avoid or reduce the backward swing of the air outlet curtain 12. Of course, the terminal device 1 can also solve the backward swinging problem through other ways, such as setting an unfolding guide rail, or setting a counterweight at the lower end of the air outlet curtain 12, etc., which will not be repeated here.

[0072] In some embodiments of the terminal device of the present invention, Figure 1-5As shown, when the air curtain 12 is fully unfolded, the height H of the air curtain 12 is greater than half the height of the wall on which it is located. The greater the height H of the air curtain 12 when it is fully unfolded, the larger the air outlet area and the larger the air outlet range, which can achieve large-area and multi-angle air outlet. On the other hand, the greater the height H of the air curtain 12 when it is fully unfolded, the larger its volume will be when it is in the rolled-up state, and it will occupy more indoor space. In actual use, it is necessary to comprehensively consider various factors to set the specific height of the air curtain 12 when it is fully unfolded.

[0073] When the air conditioner is working, the cold air flow will sink downwards, and the hot air flow will float upwards, which will cause indoor temperature stratification or uneven indoor temperature. In the prior art, because the air outlet panel is too small or the height range of the air outlet panel is too small, in order to solve the indoor temperature stratification or uneven indoor temperature caused by cold and hot air, usually only the air outlet speed and air outlet direction can be addressed, that is, the air outlet speed is increased, and the cold air is blown upwards and the hot air is blown downwards. Although this technical solution solves the indoor temperature stratification problem to a certain extent, due to the high air outlet speed, it is easy to cause user discomfort when blowing directly to the user, and the user experience is poor. In this embodiment, since the height of the air outlet curtain 12 after unfolding is greater than half the height of the wall where it is located, the air outlet holes 14 on the air outlet curtain 12 are distributed in a larger range along the upper and lower sides. When the air conditioner is cooling, part or all of the hot air flow is blown out from the lower end of the air outlet curtain 12. Even if the speed is slow when blowing out, it can float upward while flowing forward after blowing out. When the air conditioner is heating, part or all of the hot air flow is blown out from the upper end of the air curtain 12. Even if the blowing speed is slow, it can flow forward and settle downward after being blown out. In this way, the problem of indoor temperature stratification or uneven indoor temperature is solved while avoiding or reducing strong wind blowing directly on the user.

[0074] In some embodiments of the terminal device of the present invention, when the air curtain 12 is fully unfolded, the height of the air curtain 12 is equal to the height of the wall on which it is located. In this embodiment, the air curtain 12 is unfolded to the same height as the wall on which it is located, further increasing the air outlet area and air outlet range, while avoiding or reducing strong wind blowing directly on the user, and further improving the uniformity of indoor temperature distribution and avoiding indoor temperature stratification.

[0075] In some embodiments of the terminal device of the present invention, Figure 1-3 As shown, the width W of the air outlet curtain 12 is greater than one third of the width of the wall on which it is located.

[0076] The larger the width of the air curtain 12, the larger the air outlet area and air outlet range, which will bring better air outlet effect. On the other hand, since indoor walls are usually provided with doors, windows or storage furniture is provided near the walls, if the width of the air curtain 12 is too large, it is easy to interfere with the doors, windows or storage furniture. Therefore, in actual use, it is necessary to comprehensively consider various factors to set the width of the air curtain 12.

[0077] In some embodiments of the terminal device of the present invention, Figure 1-3 As shown, one reel 15 may correspond to one air curtain 12, or may correspond to multiple air curtains 12. The widths and the heights when unfolded of the multiple air curtains 12 may be the same or different. For example, the length of the reel 15 is the width of two air curtains 12, and the two air curtains 12 may be wound side by side on one reel 15 along their width direction. In actual use, when unfolding the air curtains 12, all the air curtains 12 may be unfolded at the same time, or some of the air curtains 12 may be unfolded, and the remaining air curtains 12 may be kept rolled up. Of course, some of the air curtains 12 may also be unfolded in sequence.

[0078] In some embodiments of the terminal device of the present invention, Figure 4-5 As shown, the air outlet curtain 12 includes a front wall 121 and a rear wall 122. A cavity is formed between the front wall 121 and the rear wall 122, and the cavity is a communicating air passage 13.

[0079] In this embodiment, the front wall 121 and the rear wall 122 can be two wall surfaces, which are fixedly connected or integrally formed. The front wall 121 and the rear wall 122 can also be a wall surface with a certain thickness, and the interior of the wall surface has a cavity. It should be noted that the cavity can be one or more. Multiple cavities can be interconnected or isolated from each other. In actual application, the cavity can be set according to the shape and position of the air outlet 14 and the specific structure of the air inlet pipe 11.

[0080] In some embodiments of the terminal device of the present invention, the air outlet curtain 12 further includes a plurality of ducts sandwiched between the front wall 121 and the rear wall 122, and the plurality of ducts are the communicating air passages 13. In this embodiment, the plurality of ducts may be interconnected or isolated from each other.

[0081] In some embodiments of the terminal device of the present invention, the air outlet 14 is connected to the air inlet pipe 11 via the connecting air channel 13 and the reel 15. The reel 15 is provided with a hollow connecting air channel inside, and the connecting air channel connects the connecting air channel 13 and the air inlet pipe 11.

[0082] Since the reel 15 is rotatably arranged, the reel 15 will rotate relative to the air inlet pipe 11, and at the same time, the connection between the air outlet curtain 12 and the reel 15 will also rotate relative to the air inlet pipe 11. When the connecting air duct 13 is directly connected to the air inlet pipe 11, it is necessary to additionally set up a docking mechanism that can rotate relatively. In this embodiment, a hollow connecting air duct is arranged inside the reel 15, and the connecting air duct can be arranged at the axis of the reel 15. The air inlet pipe 11 and the connecting air duct are arranged coaxially. In this way, when the reel 15 rotates, the connecting air duct and the air inlet pipe 11 can rotate coaxially relative to each other. The connecting air duct and the air outlet curtain 12 do not rotate relative to each other, and the connecting air duct can be directly fixedly connected to the connecting air duct 13 inside the air outlet curtain 12.

[0083] In some embodiments of the air conditioner of the present invention, Figure 1-3 As shown, the air conditioner includes the above-mentioned terminal device 1. The air conditioner can be an integrated air conditioner, a split air conditioner, a central air conditioning system or a fresh air system, etc. The terminal device 1 is the terminal air outlet device of the air conditioner, which blows the temperature-controlled airflow or the fresh airflow of the air conditioner out from the air outlet curtain 12.

[0084] In some embodiments of the air conditioner of the present invention, Figure 1-3 As shown, the air conditioner further comprises an outdoor unit 5 and a return air duct 6. The air inlet duct 11 is connected to the air outlet of the outdoor unit 5, one end of the return air duct 6 is connected to the return air outlet of the outdoor unit 5, and the other end of the return air duct 6 is located in the room where the terminal device 1 is located.

[0085] In this embodiment, the outdoor unit 5 may include a heat exchanger, a fan, etc. The heat exchanger generates a temperature-adjusting airflow or a fresh airflow. Under the action of the fan, the airflow is transported from the air outlet through the air inlet pipe 11 to the air outlet curtain 12, and finally blown out from the air outlet 14. In other embodiments of the air conditioner of the present invention, the fan is not arranged in the outdoor unit 5, but in the air inlet pipe 11. The fan extracts the temperature-adjusting airflow or the fresh airflow from the air outlet of the outdoor unit 5, and then transports it to the air outlet curtain 12.

[0086] In this embodiment, the inlet of the return air duct 6 can be located near the indoor ceiling, wall, floor, etc. The return air duct 6 can be one or more inlets. For example, the return air duct 6 has two inlets with opening and closing functions, one at a higher position on the wall and the other at a lower position on the wall. When the air conditioner is cooling, the inlet at a higher position is opened and the other inlet at a lower position is closed to draw away the hotter air, which is then blown out from the air curtain 12 after being cooled by the outdoor unit 5. When the air conditioner is heating, the air curtain 12 blows out air, the inlet at a lower position is opened and the inlet at a higher position is closed to draw away the colder air, which is then blown out from the air curtain 12 after being heated by the outdoor unit 5.

[0087] In some embodiments of the air conditioner control method of the present invention, Figure 6 As shown, the control method includes:

[0088] S1 obtains the operating mode of the air conditioner;

[0089] S2 controls the reel 15 to rotate according to the operation mode, so that the air outlet curtain 12 is unfolded according to a preset unfolding degree.

[0090] In this embodiment, when the air curtain 12 is fully rolled up, its expansion degree is 0%, and when the air curtain 12 is fully unfolded, its expansion degree is 100%, and the preset expansion degree is a preset value between 0% and 100%. The operation mode of the air conditioner can be a temperature adjustment mode, such as a cooling mode or a heating mode. It can also be a blowing mode, such as a strong wind mode or a breeze mode. It can also be a ventilation mode, such as a dehumidification mode, a humidification mode, or a fresh air mode. Of course, it can also be a combination of different modes.

[0091] Since the air outlet curtain 12 of the present application has an unfolded and rolled-up state, the number or total area of ​​the open air outlet holes 14 and the air outlet range of the air outlet holes 14 can be adjusted by controlling the rotation of the reel 15, which can be conveniently matched to the operating mode required by the user, enriching the application scenarios or mode settings of the air conditioner and providing users with a good usage experience.

[0092] In some embodiments of the air conditioner control method of the present invention, Figure 7 As shown, the control scroll 15 rotates, and further comprises:

[0093] S211 obtains indoor temperature and target temperature;

[0094] S212 controls the rotation of the reel 15 according to the absolute value of the difference between the indoor temperature and the target temperature, and the preset unfolding degree is positively correlated with the absolute value of the difference.

[0095] In this embodiment, the indoor temperature is the current actual temperature, which can be the actual temperature of a preset monitoring point in the room, or the average value of the actual temperature of multiple preset monitoring points or the entire room. The target temperature is the temperature expected by the user, which can be set manually by the user, or preset or intelligently set by the air conditioner. The difference between the indoor temperature and the target temperature can be positive or negative, which corresponds to the cooling mode and the refrigeration mode respectively. When the absolute value of the difference between the indoor temperature and the target temperature is large, it means that the current actual temperature is far from the temperature expected by the user, and the temperature needs to be adjusted as soon as possible. Therefore, the control increases the expansion degree of the air curtain 12, increases the number or total area of ​​the open air outlet 14, so as to increase the air volume of the temperature-adjusting airflow, and realizes rapid temperature adjustment. When the absolute value of the difference between the indoor temperature and the target temperature is small, it means that the current actual temperature is far from the temperature expected by the user, and the temperature needs to be adjusted slowly or maintained as it is. Therefore, the control reduces the expansion degree of the air curtain 12, reduces the number or total area of ​​the open air outlet 14, so as to reduce the air volume of the temperature-adjusting airflow, and realizes slow temperature adjustment.

[0096] In this embodiment, at a certain difference, the number or total area of ​​the opened air outlet holes 14 can be comprehensively set according to the indoor area and the arrangement area of ​​the air outlet holes 14 to achieve an optimal ratio.

[0097] In this embodiment, when the air conditioner is in automatic mode, when it is detected that the indoor temperature deviates from the target temperature, the rotation speed of the reel 15 is controlled so that the air curtain 12 is unfolded to a preset unfolding degree at a preset speed, or unfolded to a preset unfolding degree within a preset time. For example, when the preset unfolding degree is 100%, the preset time is set to 10 seconds. When it is detected that the indoor temperature is within the target temperature range, the rotation speed of the reel 15 is controlled so that the air curtain 12 is rolled up at a preset speed, or rolled up within a preset time.

[0098] In some embodiments of the air conditioner control method of the present invention, Figure 8 As shown, the control of the reel 15 to rotate according to the operation mode includes:

[0099] S221 In response to the operation mode being the heating mode, the roller 15 is controlled to rotate so that the air outlet curtain 12 is unfolded to at least a first preset unfolding degree, and the first preset unfolding degree is greater than 80%.

[0100] In the present embodiment, when the operation mode is the heating mode, since the hot air flow will float upward, at this time, it is necessary to lower the position of the air outlet 14 as much as possible. Therefore, for the terminal device 1 in which the roller 15 is horizontally arranged and is at the top of the room, and the air curtain 12 is unfolded downward, its first preset unfolding degree is set to be greater than 80%, so that the position of the air outlet 14 at the bottom end of the air curtain 12 is as close to the ground as possible, so as to improve the indoor temperature stratification and improve the uniformity of the indoor temperature.

[0101] Of course, for the terminal device 1 in which the reel 15 is horizontally arranged and located at the bottom of the room, and the air curtain 12 is unfolded upward, based on the same principle, the first preset unfolding degree can be set to be less than 50%, which will not be repeated here.

[0102] In some embodiments of the air conditioner control method of the present invention, Figure 8 As shown, the control of the reel 15 to rotate according to the operation mode includes:

[0103] S222: In response to the operation mode being the cooling mode, control the roller 15 to rotate so that the air outlet curtain 12 is unfolded to a second preset unfolding degree at most, and the second preset unfolding degree is less than 50%.

[0104] In the present embodiment, when the operation mode is the cooling mode, since the cold air flow will settle downward, at this time, it is necessary to raise the position of the air outlet 14 as much as possible. Therefore, for the terminal device 1 in which the roller 15 is horizontally arranged and is at the top of the room, and the air curtain 12 is unfolded downward, its second preset unfolding degree is set to be less than 50%, so that the position of the air outlet 14 at the bottom end of the air curtain 12 is as close to the top wall as possible, so as to improve the indoor temperature stratification and improve the uniformity of the indoor temperature.

[0105] Of course, for the terminal device 1 in which the reel 15 is horizontally arranged and located at the bottom of the room, and the air curtain 12 is unfolded upward, based on the same principle, the first preset unfolding degree can be set to be greater than 80%, which will not be repeated here.

[0106] In some embodiments of the air conditioner control method of the present invention, Figure 8 As shown, the control of the reel 15 to rotate according to the operation mode includes:

[0107] In step S223, in response to the operating mode being the swing wind mode, the roller 15 is controlled to rotate so that the air curtain 12 is cyclically unfolded and retracted between a third preset unfolding degree and a fourth preset unfolding degree. The third preset unfolding degree is smaller than the fourth preset unfolding degree.

[0108] In this embodiment, when the operation mode is the swing wind mode, the air curtain 12 can be cyclically unfolded and reeled in by controlling the rotation of the reel 15. Therefore, for the terminal device 1 in which the reel 15 is horizontally arranged and located at the top of the room, and the air curtain 12 is unfolded downward, when the air curtain 12 is unfolded and reeled in, the unfolded area of ​​the air curtain 12 will form an upward and downward movement, and the air outlet 14 set in the unfolded area will move accordingly, that is, when the air outlet 14 blows air outward, the air flow will also have an initial upward or downward velocity. In this way, the upward and downward uniformity of the air outlet of the air conditioner is further improved, which is convenient for adjusting the temperature of the entire indoor space or injecting fresh air.

[0109] In this embodiment, the swing mode can be combined with the heating mode. For example, for the terminal device 1 in which the reel 15 is horizontally arranged and is at the top of the room, and the air curtain 12 is unfolded downward, the third preset expansion degree can be set to 50%, and the fourth preset expansion degree can be set to 100%. The swing mode can be combined with the cooling mode. For example, for the terminal device 1 in which the reel 15 is horizontally arranged and is at the top of the room, and the air curtain 12 is unfolded downward, the third preset expansion degree can be set to 0%, and the fourth preset expansion degree can be set to 50%. The swing mode can be combined with other temperature control modes, ventilation modes or fresh air modes. The specific values ​​of the third preset expansion degree and the fourth preset expansion degree can be set to an optimal range based on comprehensive consideration of parameters such as the indoor area, volume, position of the reel 15, width of the air curtain 12 and height when fully unfolded.

[0110] In some embodiments of the air conditioner control method of the present invention, the control method further includes:

[0111] In response to the operating mode being the swing mode, the reel 15 is controlled to rotate at a preset rotation speed.

[0112] In this embodiment, when the air curtain 12 is cyclically unfolded and rolled up between the third preset unfolding degree and the fourth preset unfolding degree, it can be unfolded and rolled up at different speeds according to different usage scenarios under the drive of different preset rotation speeds of the reel 15. For example, when it is detected that the indoor temperature distribution is uneven or the temperature stratification is serious, the reel 15 is controlled to rotate at a larger preset rotation speed, so that the air outlet holes 14 in the unfolding area of ​​the air curtain 12 have a larger moving speed, driving the air flow to tilt and swing, and by changing the speed direction of the air flow and accelerating the indoor air circulation, the uniformity of the indoor temperature is improved and the temperature stratification is reduced.
