Realize cooling or heating. FIG. 5 is a schematic flowchart of the control method of the air conditioner 100 shown in FIG. 1. The control method of the air conditioner 100 according to the embodiment of the present invention includes the steps:

S502: The air conditioner 100 is in a heating state, and when a user is detected in the surrounding environment where the indoor unit of the air conditioner 100 is located or when the air conditioner 100 receives a natural wind control instruction, the air conditioner 100 is controlled to supply air in a natural wind mode ；

S504: Adjust the frequency of the compressor 170 of the air conditioner 100 and the rotation speed of the fan 120 of the indoor unit based on the coil temperature of the heat exchanger 220 of the indoor unit and the preset temperature threshold.

Generally, when the air conditioner 100 is running under strong heat, the air conditioner 100 will blow directly on the human body, especially when the user is facing the air conditioner 100, the hot air will blow directly on the human body parts, especially the human face, making the user feel uncomfortable , The face is dry and unbearable. The control method of the air conditioner 100 of the present invention proposes that when the air conditioner 100 is in a heating state, the air conditioner 100 is set to detect the presence of a user in the surrounding environment where the indoor unit of the air conditioner 100 is located or receive the air conditioner 100 When the natural wind control command is reached, the air conditioner 100 is controlled to supply air in the natural wind mode, so that the air conditioner 100 automatically and forcibly turns on the natural air supply mode when certain conditions are met, so as to avoid the dry feeling caused by the direct blowing of hot air on the body parts And discomfort, and improve the user’s blowing experience; at the same time, the control method of the air conditioner 100 of the present invention is also based on the coil temperature of the heat exchanger 220 of the indoor unit and the preset temperature threshold to adjust the frequency of the compressor 170 and the indoor unit The rotation speed of the fan 120 is adjusted to make the control of the entire air conditioner 100 more precise and refined; the air conditioner 100 as a whole realizes intelligent control, which not only saves energy, but also meets user needs and improves user comfort experience.

The air conditioner 100 of the embodiment of the present invention further includes a swing leaf assembly 140. As shown in FIG. 3, the swing leaf assembly 140 includes a plurality of horizontal swing leaves 160 and a plurality of vertical swing leaves 150. A plurality of oscillating blades 160 extend horizontally and are used to adjust the air outlet in the up and down direction, and are composed of a oscillating blade body 161, a connecting rod 162, a long shaft and a short shaft. The long rotating shaft is embedded in the air duct frame 130 and can rotate up and down with the pulling of the connecting rod 162. The short rotating shaft is embedded in the connecting rod 162 and can rotate with the rotation of the connecting rod 162. There are also a plurality of protrusions 163 randomly set on the swing leaf body 161. The protrusions 163 are preferably 2-4mm in height and are elliptical, with a short axis length of 2-4mm and a major axis length of 4-6mm, and their main function is to oppose each other. The wind disperses in different directions. The plurality of oscillating blades 160 can be pivoted synchronously to adjust the up and down direction of the wind. A plurality of vertical swing blades 150 are vertically extended and used for adjusting the left and right direction of wind. The plurality of vertical swing blades 150 can be pivoted synchronously to adjust the left and right direction of the wind. In some embodiments, each oscillating blade 160 is sequentially formed with a plurality of bending structures in the left and right directions; each vertical blade 150 is sequentially formed with a plurality of bending structures in the up and down directions. For example, each horizontal swing leaf 160 is wave-shaped in the left-right direction, and each vertical swing leaf 150 is wave-shaped in the up-down direction to disperse the wind. In the control method of the air conditioner 100 according to the embodiment of the present invention, in the natural wind mode, the swing angle of the plurality of horizontal swing blades 160 is adjusted intermittently, and the swing angle of the plurality of vertical swing blades 150 is adjusted intermittently. The air conditioner 100 of the embodiment of the present invention improves the structure of the horizontal swing leaf 160 and the vertical swing leaf 150, the horizontal swing leaf 160 is arranged in a wave shape as a whole and has a plurality of protrusions 163, and the vertical swing leaf 150 is set at the same time. The whole body is wavy, and the intermittent adjustment of the horizontal swing leaf 160 and the vertical swing leaf 150 can make the blowing method closer to the natural wind, and improve the user's blowing experience.

In some embodiments, the step of intermittently adjusting the swing angle of the plurality of oscillating leaves 160, and the step of intermittently adjusting the swing angle of the plurality of vertical oscillating leaves 150 includes: controlling the plurality of oscillating leaves 160 to swing once every first preset time. The angle, the multiple vertical swing blades 150 are simultaneously controlled to adjust the swing angle every second preset time. The first preset time is, for example, 1s, 2s, 3s, and generally does not exceed 5s. The second preset time is, for example, 1s, 2s, 3s, and generally does not exceed 5s. The first preset time and the second preset time may be the same or different. In some embodiments, the first preset time is equal to the second preset time. In other words, the horizontal swing leaf 160 and the vertical swing leaf 150 start to swing at the same time and then stop swinging at the same time. The range of the maximum swing angle of the plurality of swing blades 160 in the up and down direction is 20°-160°. The range of the maximum swing angle of the plurality of vertical swing blades 150 in the left-right direction is 0°-180°. The swing angle of the horizontal swing leaf 160 adjusted at one time is usually 10°-30°, and the swing angle of the vertical swing leaf 150 adjusted at one time is usually 10°-30°. The swing angle of the horizontal swing blade 160 adjusted at one time and the swing angle of the vertical swing blade 150 adjusted at one time may be the same or different. For example, the swing angle of the horizontal swing blade 160 adjusted at one time is 20°, and the swing angle of the vertical swing blade 150 adjusted at one time is 20°. For another example, the swing angle of the horizontal swing leaf 160 adjusted at one time is 10°, and the swing angle of the vertical swing leaf 150 adjusted at one time is 30°.

In step S502, when the air conditioner 100 receives the natural wind control instruction, it controls the air conditioner 100 to supply air in the natural wind mode. The indoor unit also includes a receiving device 190 for receiving natural wind control instructions. For example, the remote controller corresponding to the air conditioner 100 is provided with a natural wind button for triggering a natural wind control instruction. The user triggers the natural wind control instruction by pressing or clicking the natural wind button, and the natural wind control triggered by the natural wind button is detected. When the instruction is given, the control terminal such as the remote controller sends the natural wind control instruction to the receiving device 190. After the receiving device 190 receives the natural wind control instruction, the control device 200 controls the air conditioner 100 to supply air in a natural wind mode.

In step S502, when it is detected that there is a user in the surrounding environment where the indoor unit of the air conditioner 100 is located, the air conditioner 100 is controlled to supply air in a natural wind mode. The indoor unit further includes a detection device 180 configured to detect whether there is a user in the surrounding environment where the indoor unit is located. The detection device 180 may be an intelligent human body/face sensing device.

In some embodiments, in step S502, the step of detecting whether there is a user in the surrounding environment where the indoor unit is located includes:

Determine whether there is a human body image in the image;

Using this detection step has the advantages of simple steps and easy operation.

In other embodiments, in step S502, the step of detecting whether there is a user in the surrounding environment where the indoor unit is located includes:

Determine whether there are face images in multiple images;

That is to say, the control method of the air conditioner 100 of the present invention considers that there is a user in the surrounding environment where the indoor unit is located only when a face image continues to exist in the surrounding environment in a predetermined area in front of the indoor unit within a period of time. This can improve the accuracy of the judgment and eliminate the occasional situation where the user appears in front of the indoor unit. For example, the user controls the air conditioner 100 to enter the heating state by touching a control button on the indoor unit, and after completing the operation, sits down on a sofa facing the air outlet 113 of the indoor unit. Correspondingly, the detection device 180 first obtains an image of the surrounding environment in a predetermined area in front of the indoor unit, and obtains the image when the user touches the control button on the indoor unit as the first image, and further determines that there is a face image in the first image . At an interval of 40s, the detection device 180 again obtains an image of the surrounding environment in the predetermined area in front of the indoor unit, and obtains the image of the user sitting on the sofa directly opposite the indoor unit, which is the second image, and further determines that there is a person in the second image Face image. Thus, it is determined that there is a user in the surrounding environment where the indoor unit is located, and the air conditioner 100 blows air in a natural wind mode. For another example, the user controls the air conditioner 100 to enter the heating state by touching a control button on the indoor unit, and quickly leaves the environment where the indoor unit is located after completing the operation, for example, enters another room. Correspondingly, the detection device 180 first obtains an image of the surrounding environment in a predetermined area in front of the indoor unit, and obtains the image when the user touches the control button on the indoor unit as the first image, and further determines that there is a face image in the first image . At an interval of 40s, the detection device 180 acquires an image of the surrounding environment in a predetermined area in front of the indoor unit again to obtain a second image, and further determines that there is no face image in the second image. Therefore, it cannot be determined that there are users in the surrounding environment where the indoor unit is located, and the air conditioner 100 maintains the current operation mode to blow air. The predetermined area is, for example, an area within an angular range of 160° based on the plane of the entire unit, and another example is an area that is greatly affected by the air supply mode of the indoor unit. The preset time can be, for example, 1s, 20s, 40s, etc., and usually does not exceed 1 min. It can be understood that in this judgment method, the users in the front and back images can be the same user or different users, as long as there is a continuous presence of face images in the surrounding environment in a predetermined area in front of the indoor unit within a period of time. There are users in the surrounding environment where the indoor unit is located. In this way, the control method of the air conditioner 100 of the present invention can improve accuracy while not being too complicated, thereby reducing the accuracy requirements of the detection device 180 and saving costs.

In some embodiments, before the step of detecting whether there is a user in the surrounding environment where the indoor unit is located, the method further includes:

Determine whether the air conditioner 100 enters the heating state for the first time;

If yes, obtain multiple exhaust temperatures of the compressor 170;

The air conditioner 100 enters the heating state for the first time can include two situations, one is that the air conditioner 100 is powered on for the first time and enters the heating state, and the other is that the air conditioner 100 is not powered on for the first time but enters the heating state for the first time or is turned on for the first time. The cooling state or the air supply state is switched to the heating state. The control method of the air conditioner 100 of the present invention detects whether there is a user in the surrounding environment where the indoor unit is located after the detected exhaust temperature enters a stable state. The preset temperature difference threshold may be, for example, 1°C, 2°C, and 3°C.

In some embodiments, in step S504, the step of adjusting the frequency of the compressor 170 of the air conditioner 100 and the rotation speed of the fan 120 of the indoor unit based on the coil temperature of the indoor unit and the preset temperature threshold includes:

Obtain the coil temperature of the heat exchanger 220 of the indoor unit in real time;

When the coil temperature is less than the preset temperature threshold, control the compressor 170 to run at the first preset frequency and the fan 120 to run at the first preset speed;

When the coil temperature is greater than or equal to the preset temperature threshold, the compressor 170 is controlled to run at the second preset frequency, and the fan 120 runs at the second preset speed, where the second preset frequency is less than the first preset frequency, and the second preset frequency The rotation speed is set to be less than the first preset rotation speed.

The control method of the air conditioner 100 of the present invention reduces the frequency of the compressor 170 and reduces the speed of the fan 120 by setting the coil temperature of the heat exchanger 220 of the indoor unit to be greater than or equal to the preset temperature threshold, which can prevent the coil temperature from being too high. Frequent protection. The preset temperature threshold may be 60°C±5°C, for example, 55°C, 60°C, or 65°C. The first preset frequency may be the optimal frequency set by the air conditioner 100 when it leaves the factory, for example, 75 Hz. The first preset rotation speed may be the optimal rotation speed set by the air conditioner 100 when it leaves the factory, for example, 960 r/min. The second preset frequency is less than the first preset frequency, and may be, for example, 70 Hz, 65 Hz, or 60 Hz. The second preset rotation speed is less than the first preset rotation speed, and may be, for example, 900 r/min, 860 r/min, or 820 r/min. Taking the preset temperature threshold of 60℃, the first preset frequency of 75Hz, the first preset speed of 960r/min, the second preset frequency of 65Hz, and the second preset speed of 860r/min as an example, when it is detected When the coil temperature of the heat exchanger 220 of the indoor unit is 58°C, the compressor 170 is controlled to run at 75Hz, and the fan 120 runs at 960r/min; when the detected coil temperature of the heat exchanger 220 of the indoor unit is 62 At ℃, the compressor 170 is controlled to run at 65Hz, and the fan 120 runs at 860r/min. The detection of the coil temperature of the heat exchanger 220 of the indoor unit is performed in real time, and the control of the compressor 170 and the fan 120 according to the coil temperature is also performed in real time.
