An air supply control method of an indoor air conditioner comprises the following steps: acquiring the height H of an air supply outlet of an indoor unit of an air conditioner; acquiring a horizontal distance h between a user and an air conditioner indoor unit on the ground projection; and adjusting the air supply angle beta of the indoor unit of the air conditioner according to the height H and the horizontal distance H of the air supply outlet. When the indoor unit of the air conditioner is a hanging type machine, the height H of the air supply outlet is the installation height of the hanging type machine; when the indoor unit of the air conditioner is a cabinet type unit, the height H of the air supply outlet is the height of the cabinet type unit. If the indoor unit is a hanging type unit, the height H of the air supply outlet is detected and recorded in the controller after the indoor unit of the air conditioner is installed. When the indoor unit of the air conditioner is a cabinet unit, the height H of the air supply outlet is recorded in the controller when the air conditioner leaves the factory. When the user is just opposite to the air conditioner indoor unit, the horizontal distance h is the vertical horizontal distance projected on the ground by the user and the air conditioner indoor unit; when the user is not directly facing the air conditioner indoor unit, the horizontal distance h is the inclined horizontal distance projected on the ground by the user and the air conditioner indoor unit.
When the indoor unit of the air conditioner is a hanging type air conditioner, only one air outlet is arranged, and the air outlet is an upper air outlet or a lower air outlet.
The horizontal distance h used for detecting the projection of the user and the indoor unit of the air conditioner on the ground in the embodiment can be selected from a distance sensor, an infrared sensor, a millimeter wave radar and the like, and is preferably the millimeter wave radar.
As shown in the schematic diagram of air blowing angle adjustment shown in fig. 1, the air blowing angle β is trctan (H/H) according to the pythagorean theorem. And the air blown out by the indoor unit of the air conditioner always blows to the position of the foot surface of the user when the air is supplied according to the air supply angle, so that the discomfort of the user caused by directly blowing the wind to the face of the user is avoided.
Further optionally, the air supply angle comprises an up-down air supply angle and a left-right air supply angle, and when the user is positioned right in front of the indoor unit of the air conditioner, the up-down air supply angle of the air conditioner is adjusted; when the user is positioned in the inclined direction of the indoor unit of the air conditioner, the left and right air supply angles of the air conditioner are adjusted, and the air swept out from the indoor unit of the air conditioner is swept from the foot surface of the user no matter the air is swept up and down or from left to right.
Further optionally, an initial supply air temperature T of the air conditioner is also obtained0And the variation trend of the horizontal distance h along with time, and obtaining the variation trend delta T of the air supply temperature along with time according to the variation trend of the horizontal distance h along with time; wherein, the corresponding relation between the trend of the horizontal distance h changing along with time and the trend delta T of the air supply temperature changing along with time is stored in the controller; finally according to the initial air supply temperature T0And the variation trend delta T is used for adjusting the air supply temperature T of the air conditioner.
In the heating mode, the farther the user is away from the indoor unit of the air conditioner, the more heat loss is caused when hot wind blows to the user, and the lower the temperature felt by the user is; when the distance between the user and the indoor unit of the air conditioner is shorter, the heat loss is less when hot wind blows to the user, and the temperature felt by the user is higher. Similarly, in the cooling mode, the farther the user is away from the indoor unit of the air conditioner, the more the cold air is lost when the cold air blows to the user, and the higher the temperature felt by the user; when the distance between the user and the indoor unit of the air conditioner is shorter, the loss of cold air is less when cold air blows to the user, and the temperature felt by the user is lower. In order to ensure that the sensible temperature of the user can keep a comfortable state no matter the user is located at any indoor position, the embodiment obtains the trend delta T of the air supply temperature along with the time according to the trend of the horizontal distance h along with the time; finally according to the initial air supply temperature T0And the variation trend delta T is used for adjusting the air supply temperature T of the air conditioner. Specifically, in the cooling mode, when the horizontal distance h from the user to the indoor unit of the air conditioner is smaller, T is T ═ T0+△T(ii) a When the horizontal distance h between the user and the indoor unit of the air conditioner is increased, T is equal to T0- △ t. in heating mode, when the horizontal distance h from the user to the indoor unit of the air conditioner becomes small, T ═ T0△ T, when the horizontal distance h between user and indoor machine of air conditioner is greater, T ═ T0+△T。
The embodiment realizes automatic control of the air supply range by detecting the distance between a user and the air conditioner indoor unit of the user and the speed change information of the user relative to the air conditioner indoor unit, namely indirectly changing the air supply angle of the air conditioner, and simultaneously avoids discomfort of a direct-blowing person; meanwhile, the temperature of the air conditioner can be automatically adjusted.
Further optionally, when a plurality of users are in the room, the space where the users are located is divided into regions, the air conditioner is controlled to circularly supply air between different regions, and the air supply angle of each region is calculated according to the average value of horizontal distances H projected on the ground by all the users and the indoor unit of the air conditioner in the region and the height H of the air supply opening. According to the air supply angle control method and device, the average distance of all users in each area relative to the indoor unit of the air conditioner is calculated, the air supply angle of the area is obtained according to the calculated average distance and the height H of the air supply outlet, air is circularly swept in the areas through control, the air supply angle of each area is different, therefore, all users in the area can obtain better body feeling, and the swept air cannot directly blow to the users.
Further optionally, the area is divided according to the positions of the users relative to the air conditioner indoor unit, the area where the user located on the left side of the air conditioner indoor unit is divided into a first area, the area where the user facing the air conditioner indoor unit is located is divided into a second area, the area where the user located on the right side of the air conditioner indoor unit is divided into a third area, and the air conditioner is controlled to circularly supply air among the first area, the second area and the third area. Because the air sweeping modes in different areas are different, the air is swept up and down just opposite to the air conditioner indoor unit, and the air is swept left and right on the left side and the right side of the air conditioner, so that the air sweeping areas are divided most reasonably according to different positions of a user at the air conditioner indoor unit.
Further optionally, the wind sweeping temperature of each area obtains the variation trend Δ T of the air supply temperature of the area along with time according to the average variation trend of the horizontal distances h between all users in the area and the air conditioner indoor unit projected on the ground along with time, and finally obtains the initial air supply temperature T0And the trend Δ T to adjust the supply air temperature T in the area. In the embodiment, the change trend of the air supply temperature of the area along with the time under the average change trend is obtained by calculating the average change trend of the horizontal distances h of all users in each wind sweeping area along with the time change, so that the air supply temperature of the area is adjusted. Meanwhile, when different areas are circularly swept, the sweeping temperature of each area is adjusted, and users in all the areas can obtain good body sensing temperature.
Further optionally, when the user leaves, the information is fed back to the air conditioner main control system, and the main control system controls the air conditioner indoor unit to stop air supply, so that the power supply is saved.

step seven: in a cooling mode; when h becomes small, the temperature T is T at the moment0+ △ T, when h becomes large, at this moment the temperature T is T ═ T0△ T in heating mode, when h becomes smaller, the temperature T is at the moment, T1 ═ T0- △ T, when h becomes large, at which time the temperature T, T2 ═ T0+△T；
Wherein T belongs to [16 ℃,30 ℃; T1E [16 ℃,30 ℃) ]; T2E [16 ℃,30 ℃) ]; delta T belongs to [0 ℃,14 ℃) ];
