[0020] Optionally, the air conditioner further includes:

[0021] The second air outlet has its front edge located behind and below the lower edge of the first air outlet; the air duct is connected to both the first and second air outlets.

[0022] The second air guide plate is rotatably disposed at the second air outlet to open and close the second air outlet;

[0029] In the air conditioner control method and air conditioner of the present invention, when air is discharged from the first air outlet, at least a portion of the discharged air passes through multiple guide structures. Compared with the relatively small height of the guide structures in the prior art, the height of the guide structures in this embodiment is larger because the height of the guide structures is more than 1 / 2 of the minimum height of the air outlet channel defined by the inner side. Therefore, the guide structure has a significant guiding effect. After the air blown from the first air outlet of the air conditioner passes through multiple guide structures, the air outlet angle and / or air velocity of the first air outlet can be significantly changed, making the air outlet angle larger or the air velocity smaller, thus avoiding the air blown from the first air outlet directly blowing on the user or causing discomfort due to high air velocity. When the first air guide plate rotates to different positions, the guiding effect of the guide structures on the air discharged from the first air outlet is also different. The air outlet mode is determined based on the difference between the ambient temperature and the preset temperature. 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 bring the ambient temperature closer to the preset temperature as soon as possible. At the same time, a mode that allows at least most of the air to pass through the air guide structure can also be selected to avoid the air blowing directly on the user and causing discomfort.

[0045] Figure 1 This is a partial flowchart of a control method for an air conditioner 10 according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 8 The air conditioner 10 includes an air duct, a first air outlet 160, a first air guide plate 110, and multiple air guiding structures 120. The first air guide plate 110 is rotatably disposed at the first air outlet 160. Multiple air guiding structures 120 are arranged sequentially along the length direction of the first air guide plate 110 on its inner side surface 111. The air duct includes an air outlet surface 140 that defines an air outlet passage with the inner side surface 111. When the first air guide plate 110 is rotated to its maximum angle, the height of each air guiding structure 120 is more than half the minimum height of the air outlet passage.

[0046] When air is discharged from the first air outlet 160, at least a portion of the discharged air passes through 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 have a larger height because their height is more than half of the minimum height of the air outlet channel defined by the inner side. This makes the guiding effect of the guide structures 120 more obvious. After the air blown from the first air outlet 160 of the air conditioner 10 passes through multiple guide structures 120, the air outlet angle and / or air velocity of the first air outlet 160 can be significantly changed, making the air outlet angle larger or the air velocity smaller. This avoids the air blown from the first air outlet 160 blowing directly on the user or causing discomfort due to high air velocity. When the first air guide plate 110 rotates to different positions, the guiding effect of the guide structures 120 on the air discharged from the first air outlet 160 also varies.

[0047] In some embodiments of the present invention, the upper surface of the first air guide plate 110 is the inner surface, that is, the air flows out from the upper side of the upper surface of the first air guide plate 110.

[0048] In some other embodiments of the present invention, the lower surface of the first air guide plate 110 is the inner surface, that is, the air flows out from the lower side of the lower surface of the first air guide plate 110.

[0049] In some embodiments of the present invention, the air conditioner 10 has multiple air outlet modes, each air outlet mode including rotating the first air guide plate 110 to a corresponding preset rotation position. The control method of the air conditioner 10 includes:

[0050] Step S100: Obtain the ambient temperature and the preset temperature.

[0051] One of several airflow modes is executed based on the difference between the ambient temperature and the preset temperature.

[0052] The air outlet mode is determined based on the difference between the ambient temperature and the preset temperature. For example, if the difference between the ambient temperature and the preset temperature is large, an air outlet mode with a larger air volume can be selected to bring the ambient temperature closer to the preset temperature as soon as possible. At the same time, a mode in which at least most of the air outlet passes through the air guide structure 120 can be selected to avoid the air outlet blowing directly on the user and causing discomfort.

[0053] In some embodiments of the present invention, such as Figure 5 As shown, the multiple air outlet modes include a first air outlet mode. In the first air outlet mode, when the first air guide plate 110 is in a preset rotation position, the distance between the multiple air guide structures 120 and the air outlet surface 140 is equal to a preset distance value, and the preset distance value ranges from 0 to 10 mm.

[0054] In the first air outlet mode, most of the airflow passes through the guide structure 120, thus preventing the airflow from the first air outlet 160 from blowing directly on the user or causing discomfort due to high airflow velocity. However, it should be noted that the height of the guide structure 120 does not affect the opening and closing of the air outlet of the first air guide plate 110.

[0055] Further, in some embodiments of the present invention, a plurality of flow guiding structures 120 are configured to form a first flow guiding zone, a second flow guiding zone, and a third flow guiding zone on corresponding sides of the first air guide plate 110. The first flow guiding zone is used to accelerate the flow of the corresponding outlet air, the second flow guiding zone is used to cause the corresponding outlet air to flow to one lateral side of the first air guide plate 110, and the third flow guiding zone is used to cause the corresponding outlet air to flow to the other lateral side of the first air guide plate 110 away from the first flow guiding zone. The first flow guiding zone is located between the second and third flow guiding zones. The plurality of flow guiding structures 120 includes at least one first flow guiding structure for forming the first flow guiding zone. The at least one first flow guiding structure forms one or more flow guiding channels extending along the outlet air flow direction. The narrowest point of the flow guiding channel is located downstream of the inlet of the flow guiding channel. The plurality of flow guiding structures 120 also includes a plurality of second flow guiding structures for forming the second flow guiding zone and a plurality of third flow guiding structures for forming the third flow guiding zone. Each second flow guiding structure and each third flow guiding structure is sheet-like. Each second and third airflow guiding structure extends along the airflow direction and gradually deflects towards both ends of the length of the first airflow guide plate 110. In other words, after passing through the airflow guiding structure, the airflow in the middle area of ​​the first airflow guide plate is accelerated and flows out after passing through the airflow channel, while the airflow on both sides of the middle area is guided to diffuse and blow out to both sides, thus avoiding the airflow blowing directly on people.

[0056] In some embodiments of the present invention, such as Figure 1 As shown, one of several air outlet modes is executed based on the difference between the ambient temperature and the preset temperature, including:

[0057] Step S201: When the air conditioner 10 is in cooling mode and the ambient temperature is equal to the preset temperature, the first air outlet mode is executed. This first mode is also called the gentle breeze mode.

[0058] At this time, the difference between the ambient temperature and the preset temperature is not large. Using the soft wind mode can make the airflow gentler after passing through the 120-degree airflow guide structure. Even if the airflow blows forward, it will not make the user feel uncomfortable.

[0059] Furthermore, in some embodiments of the present invention, the air conditioner 10 includes a compressor. 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.

[0060] In step S201, the control method for the air conditioner 10 also includes operating the compressor at a first frequency. That is, since the ambient temperature is equal to the preset temperature, it is only necessary to maintain the current ambient temperature. Here, the first frequency is a low frequency, resulting in a higher air outlet temperature, which saves energy. The above settings can achieve a more uniform ambient temperature and a gentler airflow that doesn't blow directly on the user.

[0061] In some embodiments of the present invention, such as Figure 6 As shown, the first air outlet has a lower edge and an upper edge extending in the lateral direction. The air outlet surface is connected to the lower edge. The rear edge 141 of the air outlet surface 140 is lower than the lower edge 162 of the first air outlet 160. Multiple air outlet modes include a second air outlet mode. In the second air outlet mode, when the first air guide plate 110 is in a preset rotation position, 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 opens the first air outlet 160 at its maximum angle. The air outlet surface 140 is tilted forward and upward. When air is discharged in the second air outlet mode, the air passes through the air outlet surface 140 and blows forward and upward. At this time, part of the air is guided by the flow guide structure 120, and the other part is directly blown upward. This setting can prevent cold air from blowing directly on the user.

[0062] Furthermore, in some embodiments of the present invention, such as Figure 6 As shown, the second air guide plate 170 includes a straight section and an upwardly curved 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 upwardly curved section connects to the rear edge 141 of the air outlet surface 140.

[0063] The above configuration ensures that when the second air outlet 180 is closed, the air passes through the upper surfaces of the straight and upturned sections of the second air guide plate 170, then through the air outlet surface 140, and blows forward and upward, before exiting from the first air outlet 160, causing the air blown from the first air outlet 160 to rise.

[0064] In some embodiments of the present invention, such as Figure 2 As shown, one of multiple air outlet modes is executed based on the difference between the ambient temperature and the preset temperature. This includes step S202, where, when the air conditioner 10 is in cooling mode, and the difference between the ambient temperature and the preset temperature is less than or equal to the preset difference but not equal to the preset temperature, a second air outlet mode is executed. This second air outlet mode is also called the blower mode. All the cooling air from the air conditioner 10 is blown out from the front and above the first air outlet 160, preventing the user from being directly blasted by the airflow. The preset difference here is 1° to 3°, preferably 2°.

[0065] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has a third frequency and a fourth frequency, wherein the third frequency is less than the fourth frequency.

[0066] In step S202, the control method further includes controlling the compressor to operate at a fourth frequency. Since the cold air is directed away from the user, the fourth frequency can be set to a high frequency to reduce the indoor ambient temperature as quickly as possible.

[0067] In some embodiments of the present invention, such as Figure 7 As shown, the air conditioner 10 also includes a second air outlet 180 and a second air guide plate 170. The front edge of the second air outlet 180 is located behind and below the lower edge 162 of the first air outlet 160. The air duct is connected to both the first air outlet 160 and 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. The second air guide plate 170 is rotatably disposed at the second air outlet 180 to open and close the second air outlet 180. The air outlet mode also includes rotating the second air guide plate 170 to a corresponding preset rotation position. 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 are engaged, multiple air outlet modes are possible.

[0068] In some embodiments of the present invention, such as Figure 7 As shown, the multiple air outlet modes 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 their respective preset rotation 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°.

[0069] In some embodiments of the present invention, such as Figure 3 As shown, the system executes one of multiple air outlet modes based on the difference between the ambient temperature and the preset temperature. The process also includes 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 third air outlet mode is executed. At this time, the air outlet volume of the air conditioner 10 is at its maximum, so the third air outlet mode is also called the large air outlet mode. In this mode, hot air is blown towards the lower front of the indoor unit of the air conditioner 10, resulting in a significant cooling effect.

[0070] Furthermore, in some embodiments of the present invention, the compressor of the air conditioner 10 has a fifth frequency and a sixth frequency. The sixth frequency is greater than the fifth frequency.

[0071] In step S203, the control method further includes controlling the compressor to operate at a sixth frequency. Since the difference between the ambient temperature and the preset temperature is large, the sixth frequency can be set to a high frequency, resulting in a lower cold air temperature, in order to reduce the indoor ambient temperature as quickly as possible.

[0072] In some embodiments of the present invention Figure 8This is a cross-sectional view of an air conditioner 10 according to an embodiment of the present invention, showing the first air outlet 160 and the second air outlet 180 closed. In this configuration, 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. The overall appearance is regular, preventing foreign objects from entering.

[0073] In some embodiments of the present invention Figure 4 This is a flowchart illustrating a control method for an air conditioner 10 according to an embodiment of the present invention. When the air conditioner is turned on for cooling, if the difference between the room temperature and the target set temperature is zero, a gentle breeze mode is activated, and the compressor operates at a lower frequency to maintain a more uniform ambient temperature and a gentler, non-blowing airflow. If the difference is less than or equal to 2°C, a high-volume mode is activated, and the compressor operates at a higher frequency to achieve rapid cooling. When the difference is greater than 2°C, a maximum airflow mode is activated, and the compressor operates at a higher frequency to achieve rapid cooling.

[0074] This invention also provides an air conditioner 10, such as... Figure 9 As shown, the system includes a controller, which includes a memory 100, a processor 200, and a computer-executable program 150 stored in the memory 100 and running on the processor 200. When the processor 200 executes the computer-executable program 150, it implements the control method according to any of the above.

[0075] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope thereof. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
