In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any appropriate manner in any one or more embodiments or examples.

[0084] Figure 1 FIG. 1 is a flow chart of a method for controlling an air conditioner 10 according to an embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 15As shown, the air conditioner 10 includes a first air outlet 160, a first air guide plate 110 and a plurality of guide structures 120. The first air outlet 160 extends in the transverse direction. The first air guide plate 110 is rotatably arranged at the first air outlet 160, and the first air guide plate 110 extends along the length direction of the first air outlet 160. The lower surface of the first air guide plate 110 is a guide surface 111 to guide the outgoing air to flow out from the lower side of the lower surface of the first air guide plate 110. A plurality of guide structures 120 are arranged on the guide surface 111 of the first air guide plate 110 and are arranged in sequence along the length direction of the first air guide plate 110. When the first air guide plate 110 is rotated to the maximum angle, the height of each guide structure 120 is more than 1 / 2 of the minimum height of the air outlet channel defined by the lower surface.

[0085] When air is blown out of the first air outlet 160, at least a portion of the air passes through the multiple guide structures 120. Compared to the relatively small height of the guide structures 120 in the prior art, the guide structures 120 in this embodiment are relatively large because their height is at least 1 / 2 of the minimum height of the air outlet channel defined by the lower surface. This significantly improves the air diversion effect of the guide structures 120. After the air blown out of the first air outlet 160 of the air conditioner 10 passes through the multiple guide structures 120, the air outlet angle and / or air velocity of the first air outlet 160 can be significantly changed, increasing the air outlet angle or decreasing the air velocity through the first air outlet 160. This prevents the air blown out of the first air outlet 160 from directly blowing on the user or causing discomfort to the user due to the high air velocity. When the first air guide plate 110 is rotated to different positions, the guide structures 120 also have different diversion effects on the air passing through the first air outlet 160.

[0086] Of course, in other embodiments of the present invention, the upper surface of the first air guide plate 110 is the air guide surface, that is, the air flows out from the upper side of the upper surface of the first air guide plate 110 .

[0087] Therefore, based on the above embodiments, it can be said that the inner side surface of the first air guide plate 110 serves as an air guide surface, and a plurality of air guide structures 120 are disposed on the inner side surface and arranged in sequence along the length direction of the first air guide plate 110. Furthermore, when the first air guide plate 110 is rotated to its maximum angle, the height of each air guide structure 120 is at least 1 / 2 of the minimum height of the air outlet channel defined by the inner side surface.

[0088] Furthermore, in some embodiments of the present invention, multiple air guide structures 120 are configured to form a first air guide area, a second air guide area, and a third air guide area on the inner side of the first air guide plate 110. The first air guide area is used to accelerate the corresponding outgoing air flow, the second air guide area is used to direct the corresponding outgoing air flow toward a lateral side of the first air guide plate 110, and the third air guide area is used to direct the corresponding outgoing air flow toward the other lateral side of the first air guide plate 110, away from the first air guide area. The first air guide area is located between the second and third air guide areas. The multiple air guide structures 120 include at least one first air guide structure for forming the first air guide area. The at least one first air guide structure forms one or more guide channels extending in the direction of the outgoing air flow. The narrowest point of the guide channel is located downstream of the inlet of the guide channel. The multiple air guide structures 120 also include multiple second air guide structures for forming the second air guide area, and multiple third air guide structures for forming the third air guide area. Each second air guide structure and each third air guide structure is sheet-shaped. Each second and third guide structure extends along the airflow direction and gradually deflects toward both ends of the lengthwise direction of the first air guide plate 110. In other words, the air flowing through the guide structures is accelerated in the middle region of the first air guide plate after passing through the guide channel, while the air flowing on both sides of the middle region is directed and diffused to the sides, thus preventing the air from directly hitting people.

[0089] In some embodiments of the present invention, Figure 1 As shown, the air conditioner 10 has multiple air outlet modes, each of which includes rotating the first air guide plate 110 to a corresponding preset rotation position. The control method of the air conditioner 10 includes:

[0090] Step S100: Acquire the ambient temperature, the preset temperature, and the user status in the room where the air conditioner 10 is located. The user status includes whether there is a user in the room where the air conditioner 10 is located.

[0091] In step S200 , one of a plurality of air outlet modes is executed according to the difference between the ambient temperature and the preset temperature and / or whether there is a user in the room where the air conditioner 10 is located.

[0092] The air outlet mode is determined based on the difference between the ambient temperature and the preset temperature and whether there is a user in the room where the air conditioner 10 is located. For example, if the difference between the ambient temperature and the preset temperature is relatively large, an air outlet mode with a larger air volume can be selected to make the ambient temperature close to the preset temperature as soon as possible. At the same time, if there is a user in the room, while selecting a larger air outlet mode, you can also select a mode that allows at least most of the air to pass through the guide structure 120 to avoid the air blowing directly on the user and causing discomfort to the user.

[0093] In other embodiments of the present invention, the air outlet mode may also be determined based on whether there is a user in the room where the air conditioner 10 is located.

[0094] In some embodiments of the present invention, the first air outlet 160 has a lower edge 162 and an upper edge 161 extending in a transverse direction. The air conditioner 10 further includes a second air outlet 180, an air duct, and a second air guide plate 170. The front edge 171 of the second air outlet 180 is disposed behind and below the lower edge 162 of the first air outlet 160. The air duct includes an air outlet surface 140 that defines an air outlet passage with an inner side surface, and the air outlet surface 140 is connected to the lower edge 162. The air duct communicates with both the first air outlet 160 and the second air outlet 180. The second air guide plate 170 is rotatably disposed at the second air outlet 180 to open and close the second air outlet 180, and the air outlet surface 140 is located between the first air outlet 160 and the second air outlet 180. When the first air guide plate 110 is rotated to its maximum angle, the lower surface of the first air guide plate 110 becomes the inner side surface, guiding the air to flow out from between the inner side surface and the air outlet surface 140. The inner side surface is the air guide surface. Each air outlet mode also includes rotating the second air guide plate 170 to a corresponding preset rotation position.

[0095] The air passing through the air duct is blown out from the first air outlet 160 and the second air outlet 180 . When the first air guide plate 110 and the second air guide plate 170 cooperate with each other, there can be multiple air outlet modes.

[0096] In some embodiments of the present invention, Figure 10 As shown, multiple air outlet modes include a first air outlet mode. In the first air outlet mode, when the first air guide plate 110 and the second air guide plate 170 are in the corresponding preset rotation positions, the distance between the multiple guide structures 120 and the air outlet surface 140 is less than the first preset distance value, and the first preset distance value is 0 to 10 mm. The second air guide plate 170 closes the second air outlet 180.

[0097] In the first air outlet mode, at least most of the air flows through the guide structure 120, thereby preventing the air from the first air outlet 160 from directly blowing on the user or causing discomfort to the user due to the high air velocity. However, it should be noted that the height of the guide structure 120 does not affect the opening and closing of the first air outlet by the first air guide plate 110.

[0098] In some embodiments of the present invention, Figure 2 As shown, one of multiple air outlet modes is executed based on the difference between the ambient temperature and the preset temperature and / or whether there is a user in the room where the air conditioner 10 is located, including: Step S201, when the air conditioner 10 is in cooling mode, the difference between the ambient temperature and the preset temperature is less than or equal to the preset difference, and there is a user in the room where the air conditioner 10 is located, the first air outlet mode is executed. The first mode here is also called the soft wind mode. The preset difference here is 0.5° to 1.5°, preferably, the preset difference is 1°.

[0099] At this time, the difference between the ambient temperature and the preset temperature is not large, and the soft wind mode can make the wind softer after passing through the guide structure 120, and the user will not feel uncomfortable even if the wind is blown forward.

[0100] Furthermore, in some embodiments of the present invention, the air conditioner 10 includes a compressor and a fan. The compressor of the air conditioner 10 has a first frequency and a second frequency, wherein the first frequency is less than the second frequency. The fan of the air conditioner 10 has a first air volume and a second air volume, wherein the first air volume is greater than the second air volume.

[0101] In step S201, the control method of the air conditioner 10 further includes operating the compressor at a first frequency and the fan at a first air volume. In other words, since the difference between the ambient temperature and the preset temperature is small, the first frequency is low, the outlet air temperature is high, and a significant temperature reduction is not required. The first air volume is high. This configuration maintains a more uniform ambient temperature and a softer wind that does not blow on the user.

[0102] In some embodiments of the present invention, Figure 11 As shown, the multiple air outlet modes include a second air outlet mode. In the second air outlet mode, when the first air guide plate 110 and the second air guide plate 170 are in corresponding preset rotational positions, the first air guide plate 110 closes the first air outlet 160, the front edge 171 of the second air guide plate 170 is located in front of and below the rear edge 172 of the second air guide plate 170, and the angle between the second air guide plate 170 and the horizontal plane is 40° to 70°. The second air outlet mode is also called the large air outlet mode. In this mode, all the air flows through the second air outlet 180 and is blown toward the front and bottom of the indoor unit of the air conditioner 10, achieving a good cooling effect.

[0103] In some embodiments of the present invention, Figure 3 As shown, one of the multiple air outlet modes is executed according to the difference between the ambient temperature and the preset temperature and / or whether there is a user in the room where the air conditioner 10 is located, including:

[0104] In step S202, when the air conditioner 10 is in cooling mode, the difference between the ambient temperature and the preset temperature is less than or equal to the preset difference, and there is no user in the room where the air conditioner 10 is located, the second air outlet mode is executed. Since there is no user in the room, the large air outlet mode can be directly activated, blowing cooling air forward and downward, achieving a better cooling effect.

[0105] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has a third frequency and a fourth frequency, the third frequency being less than the fourth frequency. The fan of the air conditioner 10 has a third air volume and a fourth air volume, the third air volume being less than the fourth air volume. In step S202, the control method of the air conditioner 10 further includes controlling the compressor to operate at the third frequency and controlling the air volume of the fan to be the third air volume. Because the difference between the ambient temperature and the preset temperature is not large and the cooling effect is good, the third frequency and the third air volume are low, thereby maintaining the indoor temperature while saving energy.

[0106] In some embodiments of the present invention, Figure 4 As shown, one of the multiple air outlet modes is executed according to the difference between the ambient temperature and the preset temperature and / or whether there is a user in the room where the air conditioner 10 is located, and further includes:

[0107] Step S203: When the air conditioner 10 is in cooling mode and the difference between the ambient temperature and the preset temperature is greater than the preset difference, the second air outlet mode is executed. Since there is no user in the room, the large air outlet mode can be directly turned on, and the cooling air is blown forward and downward, which has a good cooling effect.

[0108] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has a fifth frequency and a sixth frequency, the fifth frequency being less than the sixth frequency. The fan of the air conditioner 10 has a fifth air volume and a sixth air volume, the fifth air volume being less than the sixth air volume. In step S203, the control method of the air conditioner 10 further includes controlling the compressor to operate at the sixth frequency and controlling the air volume of the fan to be the sixth air volume.

[0109] In some embodiments of the present invention, Figure 12 As shown, the rear edge 141 of the air outlet surface 140 is lower than the lower edge 162 of the first air outlet 160. When the second air outlet 180 is closed, the upper surface of the second air guide plate 170 is connected to the air outlet surface 140. The multiple air outlet modes also include a third air outlet mode. In the third air outlet mode, when the first air guide plate 110 and the second air guide plate 170 are in corresponding preset rotation positions, the front edge of the first air guide plate 110 is located above and in front of the rear edge of the first air guide plate 110, and the first air guide plate 110 is rotated to the maximum angle, and the second air guide plate 170 closes the second air outlet 180. At this time, the first air guide plate 110 rotates upward to fully open the first air outlet 160. The air outlet surface 140 is tilted forward and upward, and when the second air outlet 180 is closed, the upper surface of the second air guide plate 170 is connected to the air outlet surface 140. In the third air outlet mode, the air passes through the surface of the second air guide plate 170 and the air outlet surface 140 and is blown forward and upward. At this time, part of the air is guided by the guide structure 120, and the other part of the air is blown directly upward. This setting can prevent cold air from blowing directly on the user.

[0110] Furthermore, in some embodiments of the present invention, Figure 6 As shown, the second air guide plate 170 includes a straight section and an upturned section extending forward and upward from the front end of the straight section. When the second air outlet 180 is closed, the upper surface of the upturned section is connected to the air outlet surface 140.

[0111] The above arrangement ensures that when the second air outlet 180 is closed, the air passes through the upper surface of the straight section and the upward section of the second air guide plate 170, and then passes through the air outlet surface 140, and is blown forward and upward, and then blown out from the lower edge 162 of the first air outlet 160, so that the air blown out from the lower edge 162 of the first air outlet 160 rises.

[0112] In some embodiments of the present invention, Figure 4 As shown, one of the multiple air outlet modes is executed according to the difference between the ambient temperature and the preset temperature and / or whether there is a user in the room where the air conditioner 10 is located, and further includes:

[0113] When the heat exchange mode of the air conditioner 10 is the cooling mode, the difference between the ambient temperature and the preset temperature is greater than the preset difference, and the second air outlet mode is executed, step S204 is executed to determine whether the operation time is preset.

[0114] If yes, step S205 is executed to determine whether there is a user in front of the first air outlet 160 .

[0115] If so, step S206 is executed to execute the third air outlet mode.

[0116] To ensure the lifespan of the air conditioner 10, after the air conditioner 10 enters the second air outlet mode, it cannot switch to another air outlet mode too soon to change the rotational positions of the first air guide plate 110 and the second air guide plate 170. Therefore, after a preset period of time, it is determined whether a user is in front of the first air outlet 160. If so, the air conditioner 10 enters the third air outlet mode, where the cool air rises upward. Therefore, the third air outlet mode is also called the upward air mode.

[0117] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has a ninth frequency and a tenth frequency, the tenth frequency being greater than the ninth frequency, and the fan of the air conditioner 10 has a ninth air volume and a tenth air volume.

[0118] The tenth air volume is greater than the ninth air volume.

[0119] When executing the third air outlet mode, in step S206, the control method of the air conditioner 10 further includes controlling the compressor to operate at a tenth frequency and controlling the fan air volume to a tenth air volume. Since the cold air does not blow on the user and the difference between the ambient temperature and the preset temperature is large, the tenth frequency and the tenth air volume can be set to a high frequency and a high air volume to quickly lower the indoor ambient temperature.

[0120] In some embodiments of the present invention, Figure 13 As shown, the air duct has an upper air outlet wall 190, the front edge of which is spaced from the upper edge 161 of the first air outlet 160, and the rear edge of which is connected to the volute tongue. Multiple air outlet modes include a fourth air outlet mode. In this fourth air outlet mode, when the first air guide plate 110 and the second air guide plate 170 are in corresponding preset rotational positions, the second air guide plate 170 is vertical and the distance between the front edge 171 of the second air guide plate 170 and the upper air outlet wall 190 is less than a second preset distance, which is 0 to 5 mm. In other words, in the fourth air outlet mode, the second air guide plate 170 directs nearly all air downward. In this case, the first air guide plate 110 can close the first air outlet 160, but it can also be in other positions. This air outlet mode is particularly suitable for the air conditioner 10 to discharge hot air, so the fourth air outlet mode is also called the vertical heating mode. In this mode, the hot air does not blow towards the user, but blows directly to the ground, which helps the hot air fall to the ground and prevents a hot head and cold feet.

[0121] In some embodiments of the present invention, Figure 5 As shown, one of the multiple air outlet modes is executed according to the difference between the ambient temperature and the preset temperature and / or whether there is a user in the room where the air conditioner 10 is located, and further includes:

[0122] In step S211, when the air conditioner 10 is in heating mode, the difference between the ambient temperature and the preset temperature is less than or equal to the preset difference, and there is a user in the room where the air conditioner 10 is located, the fourth air outlet mode is executed. In this case, the heating air is blown directly to the ground and not toward the user, thereby avoiding user discomfort.

[0123] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has an eleventh frequency and a twelfth frequency. The twelfth frequency is greater than the eleventh frequency. The fan of the air conditioner 10 has an eleventh air volume and a twelfth air volume. The twelfth air volume is greater than the eleventh air volume.

[0124] When air conditioner 10 is in heating mode, the difference between the ambient temperature and the preset temperature is less than or equal to the preset difference, and there is a user in the room where air conditioner 10 is located, in step S211, the control method further includes: controlling the compressor to operate at an eleventh frequency and controlling the fan air volume to the eleventh air volume. Because the difference between the ambient temperature and the preset temperature is small, the eleventh frequency is low, the outlet air temperature is low, and a significant increase in temperature is not required. The eleventh air volume is low. This setting can maintain a more uniform ambient temperature and prevent hot air from blowing towards the user.

[0125] In some embodiments of the present invention, Figure 14As shown, the multiple air outlet modes include a fifth air outlet mode. In the fifth air outlet mode, when the first air guide plate 110 and the second air guide plate 170 are in corresponding preset rotation positions, the front edge of the first air guide plate 110 is located above and in front of the rear edge of the first air guide plate 110, the front edge 171 of the second air guide plate 170 is located below and in front of the rear edge 172 of the second air guide plate 170, and the angle between the second air guide plate 170 and the horizontal plane is 70° to 90°. In this case, the angle between the first air guide plate 110 and the second air guide plate 170 is the largest. At this time, air is discharged from both the first air outlet 160 and the second air outlet 180, and the angle formed by the first air guide plate 110 and the second air guide plate 170 is increased. Therefore, the fifth air outlet mode is a wide-angle heating mode with the largest air outlet range.

[0126] In some embodiments of the present invention, Figure 6 As shown, one of the multiple air outlet modes is executed according to the difference between the ambient temperature and the preset temperature and / or whether there is a user in the room where the air conditioner 10 is located, and further includes:

[0127] In step S212, when the air conditioner 10 is in heating mode, the difference between the ambient temperature and the preset temperature is less than or equal to the preset difference, and there is no user in the room where the air conditioner 10 is located, the fifth air outlet mode is executed. In this case, hot air is blown out at a large angle to ensure uniform indoor temperature without stratification.

[0128] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has a thirteenth frequency and a fourteenth frequency. The fourteenth frequency is greater than the thirteenth frequency. The fan of the air conditioner 10 has a thirteenth air volume and a fourteenth air volume. The fourteenth air volume is greater than the thirteenth air volume.

[0129] In step S212, the control method further includes controlling the compressor to operate at a thirteenth frequency and controlling the fan air volume to the thirteenth air volume. Since the difference between the ambient temperature and the preset temperature is small, the thirteenth frequency is low, the outlet air temperature is low, and a significant temperature increase is not required. The thirteenth air volume is low. This setting maintains the room temperature while also achieving energy savings.

[0130] In some embodiments of the present invention, Figure 7 As shown, one of the multiple air outlet modes is executed according to the difference between the ambient temperature and the preset temperature and / or whether there is a user in the room where the air conditioner 10 is located, and further includes:

[0131] In step S213 , when the air conditioner 10 is in the heating mode and the difference between the ambient temperature and the preset temperature is greater than the preset difference, the second air outlet mode is executed.

[0132] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has a seventh frequency and an eighth frequency. The eighth frequency is greater than the seventh frequency. The fan of the air conditioner 10 has a seventh air volume and an eighth air volume.

[0133] The eighth air volume is greater than the seventh air volume.

[0134] In step S213, the control method further includes controlling the compressor to operate at an eighth frequency and controlling the fan air volume to the eighth air volume. Because the difference between the ambient temperature and the preset temperature is large, the eighth frequency is high, resulting in a higher outlet air temperature, which can significantly increase the room temperature. The eighth air volume is high. These settings can rapidly increase the room temperature.

[0135] Furthermore, in some embodiments of the present invention, Figure 7 As shown, the control method further includes:

[0136] When the air conditioner 10 is in the heating mode, the difference between the ambient temperature and the preset temperature is greater than the preset difference, and after the second air outlet mode is executed, step S214 is executed to determine whether the operation time is preset.

[0137] If yes, step S215 is executed to determine whether there is a user in front of the first air outlet 160 .

[0138] If yes, step S217 is executed to execute the fourth air outlet mode. That is, if there is a user in front of the first air outlet 160, the second air outlet mode is switched to the fourth air outlet mode to ensure that the hot air is not blown directly onto the user.

[0139] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has a fifteenth frequency and a sixteenth frequency. The sixteenth frequency is greater than the fifteenth frequency. The fan of the air conditioner 10 has a fifteenth air volume and a sixteenth air volume. The sixteenth air volume is greater than the fifteenth air volume.

[0140] In step S217, the control method further includes controlling the compressor to operate at a sixteenth frequency and controlling the fan air volume to the sixteenth air volume. Because the difference between the ambient temperature and the preset temperature is large, the sixteenth frequency is high, resulting in a higher outlet air temperature, which can significantly increase the room temperature. The sixteenth air volume is high. These settings can rapidly increase the room temperature.

[0141] Furthermore, in some embodiments of the present invention, when the air conditioner 10 is in heating mode, the difference between the ambient temperature and the preset temperature is greater than the preset difference, and before the fourth air outlet mode is implemented, the control method further includes: step S216, rotating the first air guide plate 110 to a corresponding preset position in a direction away from the air outlet surface 140, so that when the second air guide plate 170 rotates, the air guide structure 120 avoids the second air guide plate 170. In other words, when switching from the second air outlet mode to the fourth air outlet mode, the first air guide plate 110 needs to be rotated first to make way for the second air guide plate 170 to rotate to the vertical position.

[0142] In some embodiments of the present invention, the control method further includes:

[0143] If there is no user, execute step S218 to execute the fifth air outlet mode.

[0144] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has a seventeenth frequency and an eighteenth frequency. The eighteenth frequency is greater than the seventeenth frequency. The fan of the air conditioner 10 has a seventeenth air volume and an eighteenth air volume. The eighteenth air volume is greater than the seventeenth air volume.

[0145] In step S218, the control method includes controlling the compressor to operate at an 18th frequency and controlling the air volume of the fan to be an 18th air volume. The 18th frequency is a high frequency, and the air outlet temperature is relatively high. The 18th air volume is a high air volume, which can significantly increase the temperature.

[0146] In some embodiments of the present invention, Figure 15 FIG2 is a cross-sectional view of an air conditioner 10 according to an embodiment of the present invention, with the first air outlet 160 and the second air outlet 180 closed. At this time, the first air guide plate 110 closes the first air outlet 160, and the second air guide plate 170 closes the second air outlet 180, resulting in a regular appearance and preventing foreign matter from entering.

[0147] In some embodiments of the present invention, Figure 8The flowchart of a control method for an air conditioner 10 according to an embodiment of the present invention is shown. The air conditioner is turned on for cooling, and the difference between the room temperature and the target set temperature is calculated. When the difference is less than or equal to 1°, it is determined whether there is anyone in the room. If there is, the soft wind mode is turned on, the compressor runs at a lower frequency, and the fan air volume is increased to achieve a more uniform ambient temperature and a softer wind that does not blow on people. If there is no one, the high air outlet mode is turned on, the compressor runs at a lower frequency, and the fan air volume is lower, to achieve a maintained ambient temperature and energy saving. When the difference is greater than 1°, the high air outlet mode is turned on, the compressor runs at a higher frequency, and the fan air volume is higher, to achieve rapid cooling. After the high air outlet mode has been operating for more than 1 minute, it is determined whether there is anyone in front of the air outlet. If there is, the lifting wind mode is turned on, the compressor runs at a higher frequency, and the fan air volume is higher, to achieve rapid cooling without blowing on people. The room temperature here is the ambient temperature, and the target set temperature is the preset temperature.

[0148] In some embodiments of the present invention, Figure 9 This is a flow chart of a control method for an air conditioner 10 according to one embodiment of the present invention. The air conditioner is turned on in heating mode and calculates the difference between the room temperature and the target set temperature. When the difference is less than or equal to 1°, it is determined whether there is someone in the room. If there is, the vertical heating mode is activated, with the compressor running at a lower frequency and fan volume to maintain the ambient temperature without blowing on anyone. If there is no one, the wide-angle heating mode is activated, with the compressor running at a lower frequency and fan volume to maintain the ambient temperature while saving energy. If the difference is greater than 1°, the high-flow mode is activated, with the compressor running at a higher frequency and fan volume to achieve rapid temperature increase. After operating in high-flow mode for more than one minute, it is determined whether there is someone in front of the air outlet. If there is, the vertical heating mode is activated, with the compressor running at a higher frequency and fan volume to achieve rapid temperature reduction without blowing on anyone. If there is no one, the wide-angle heating mode is activated, with the compressor running at a higher frequency and fan volume to achieve rapid temperature increase in both directions. Here, the room temperature is the ambient temperature, and the target set temperature is a preset temperature.

[0149] The embodiment of the present invention further provides an air conditioner 10, such as Figure 16 As shown, the controller includes a memory 100, a processor 200, and a computer executable program 110 stored in the memory 100 and running on the processor 200, and when the processor 200 executes the computer executable program 110, the control method according to any one of the above items is implemented.

[0150] At this point, users skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
