S403, controlling the indoor unit to operate according to the operation parameters.
By adopting the technical scheme, the air can be intensively supplied to the high place during refrigeration, and the air can be intensively supplied to the low place during heating, so that the temperature adjusting effect is good. When the operation mode is a heating mode, the air supply direction is lower than the set direction, the air supply direction can be downwards concentrated through the lower air outlet, and the hot air blown out by the indoor unit freely rises; the upper air outlet is arranged at the upper part of the panel of the indoor unit, the lower air outlet is arranged at the lower part of the panel of the indoor unit, and the highest height of the air supply direction of the upper air outlet is higher than the highest height of the air supply direction of the existing indoor unit.

the control method further comprises the following steps:
s501, acquiring user information in a space to be tempered, wherein the user information comprises the number of users.
For example, if there are no users in the air blowing area, the number of users is 0, and if there are users in the air blowing area, the number of users is not 0.
S502, determining an air supply mode of the indoor unit according to the number of users, wherein the air supply mode is used for representing air supply comfort level.
Air supply comfort refers to the experience that the air conditioner brings to the user when in operation, and air supply modes may include two, three, four or more, for example, when the air supply modes include two, the air supply modes may include: air supply without wind sense and air supply with wind sense; when the air supply modes include three, the air supply modes may include: air supply without wind sense, air supply with wind sense and air supply with strong wind sense.
Alternatively, S502 may be implemented as: determining the number level of the number of users, wherein the number level has a mapping relation with the number of the air supply modes, the number of the number level is the same as the number of the air supply modes, when the air supply modes comprise two types, the number level comprises two stages, and when the air supply modes comprise three types, the number level comprises three stages; and determining the air supply mode corresponding to the quantity grade according to the quantity grade.
For example, if the air blowing modes are two: the number of stages is two, the number of stages is 1 when the number of users is less than or equal to 3, and the number of stages is 2 when the number of users is greater than 3. The 1-stage number of stages corresponds to the air supply without the sense of wind, and the 2-stage number of stages corresponds to the sense of wind. Then, when the number of users in the air-sending area is less than or equal to 3, the air-sending mode is air-sending without sense of wind, and when the number of users in the air-sending area is more than 3, the air-sending mode is air-sending with sense of wind.
If the air supply modes are three: the number of the air supply stages is three, when the number of the users is less than or equal to 3, the number of the air supply stages is set to be 1, when the number of the users is more than 3 and less than or equal to 5, the number of the air supply stages is set to be 2, and when the number of the users is more than 5, the number of the air supply stages is set to be 3. Wherein, the 1-level quantity grade corresponds to the air supply without wind sense, the 2-level quantity grade corresponds to the air supply with wind sense, and the 3-level quantity grade corresponds to the air supply with strong wind sense. Then, when the number of users in the air-sending area is less than or equal to 3, the air-sending mode is air-sending without wind sense, when the number of users in the air-sending area is more than 3 and less than or equal to 5, the air-sending mode is air-sending with wind sense, and when the number of users in the air-sending area is more than 5, the air-sending mode is air-sending with strong wind sense.
An accurate air supply mode can be obtained, and air supply comfort is provided.
S503, determining the air supply speed of the indoor unit according to the air supply mode.
S504, determining a first rotating speed and a second rotating speed according to the first rotating angle, the second rotating angle and the air supply speed.
The first rotation angle can represent the first opening of the upper air outlet, and the second rotation angle can represent the second opening of the lower air outlet. For example, if the first rotation angle is θ, sin θ may be used to represent the first opening of the upper air outlet, and when the rotation angle θ is smaller than 90 °, the larger the first rotation angle, the larger the first opening of the upper air outlet. Regarding the first rotation angle/the second rotation angle, the first rotation angle/the second rotation angle when the upper air deflector/the lower air deflector are closed is 0, the position where the upper air deflector/the lower air deflector are positioned when the upper air deflector/the lower air deflector are closed is the initial position, and the included angle between the actual position where the upper air deflector/the lower air deflector are positioned and the initial position is the first rotation angle/the second rotation angle.
Considering that the upper air deflector/lower air deflector can rotate forward and reversely, when the upper air deflector/lower air deflector rotates forward at the upper air outlet/lower air outlet, the first rotation angle/second rotation angle theta is positive; when the upper air deflector/lower air deflector reversely rotates at the upper air outlet/lower air outlet, the first rotation angle/second rotation angle θ is negative. Therefore, the opening degree of the upper air outlet/the lower air outlet can be represented by |sin theta|.
So S504 can be implemented as: determining a first opening degree of the upper air deflector according to the first rotation angle, determining a second opening degree of the lower air outlet according to the second rotation angle, determining a first rotating speed according to the first opening degree and the first air supply speed, and determining a second rotating speed according to the second opening degree and the second air supply speed, wherein the first air supply speed and the second air supply speed form the air supply speed in a vector synthesis mode.
When a plurality of users exist in the space to be temperature-regulated, the indoor unit of the air conditioner still has better air supply comfort level.
Alternatively, the setting direction in S401 is the direction in which the user is located. For example, the direction in which the detected user's head is located is set as the set direction. When a plurality of users exist in the temperature adjusting space, a plurality of user positions are acquired, the centers of the plurality of user positions are determined, and the direction of the centers is used as a set direction. Multiple users can be considered, and the users can obtain better use experience.
As shown in fig. 6, in an alternative embodiment, when the user information further includes a user distance between the user and the indoor unit, the control method includes:
s601, determining the air supply distance according to the user distance.
Optionally, when a plurality of users exist in the space to be temperature-regulated, taking the average distance of the plurality of user distances as the air supply distance; optionally, when a plurality of users exist in the space to be temperature-regulated, the maximum distance among the distances of the plurality of users is taken as the air supply distance, so that the air supply effect on the air supply area can be ensured; optionally, when a plurality of users exist in the space to be temperature-regulated, the minimum distance among the plurality of user distances is taken as the air supply distance, so that the air supply comfort level can be improved.
S602, determining a first rotating speed and a second rotating speed according to the air supply distance, the air supply speed, the first rotating angle and the second rotating angle.
This technical scheme further improves the air supply comfort level.
In the foregoing, the first rotation angle may represent a first opening of the upper air outlet, and the second rotation angle may represent a second opening of the lower air outlet.
Optionally, S602 includes:
determining the air supply quantity according to the air supply distance and the air supply speed; wherein, the square of the air supply air quantity and the air supply distance is positively correlated, and the air supply air quantity is positively correlated with the air supply speed required by the air supply mode.
And determining a first rotating speed and a second rotating speed according to the air supply quantity, the first opening and the second opening.
The air supply air quantity comprises a first air supply air quantity of the upper air outlet and a second air supply air quantity of the lower air outlet, the rated power of the first fan is positively correlated with the maximum value of the first air supply air quantity, and the rated power of the second fan is positively correlated with the maximum value of the second air supply air quantity.
Optionally, the rated power of the first fan is greater than the rated power of the second fan. The power consumption of the indoor unit can be reduced.
Optionally, the ratio between the upper air supply air volume and the lower air supply air volume is a set value, and the upper air supply air volume and the lower air supply air volume can be respectively determined according to the air supply air volume. Optionally, the value range of the set value is 1/10-1. For example, the set value may be any of 1/10, 1/8, 1/5, 1/4, 1/2, 3/4, 4/5, 9/10.
Among a plurality of upper air deflectors at the upper air outlet, the upper air deflectors with the first rotation angle are of a first quantity, and the rest upper air deflectors are in a closed state; among the plurality of air deflectors at the lower air outlet, the lower air deflectors with the second rotation angle are in a second number, and the rest lower air deflectors are in a closed state. A first number of upper air deflectors at a first angle of rotation is used to characterize a first opening; the second number of lower air deflectors at a second angle of rotation is used to characterize a second opening.
In an alternative embodiment, when the user information further includes a user distance between the user and the indoor unit, the control method includes:
determining an air supply distance according to the user distance;
determining the air supply quantity according to the air supply speed and the air supply distance;
determining a first rotating speed and a second rotating speed according to the air supply quantity;

In an alternative embodiment, the operation parameters further include a third rotation angle of the left air deflector at the left air inlet and a fourth rotation angle of the right air deflector at the right air inlet, wherein the left air inlet is opened at the left side of the upper air inlet and the lower air inlet towards the left side of the indoor unit, and the right air inlet is opened at the right side of the upper air inlet and the lower air inlet towards the right side of the indoor unit;
