Abstract

An air conditioner control method includes determining an operation state of an air conditioner after the air conditioner is powered up, controlling an air deflector rotatably installed at an air outlet of the air conditioner to restore according to the operation state, and controlling the air deflector to adjust an air outlet angle according to an angle after restoration. Controlling the air deflector to restore includes, in response to the operation state being a turn-on state, controlling the air deflector to restore to a restoration angle that is a maximum opening angle of the air deflector when opening to expose the air outlet, and, during rotation of the air deflector, controlling air output of the air conditioner according to a rotation angle of the air deflector.

First claim

What is claimed is:

1 . An air conditioner control method comprising:
determining an operation state of an air conditioner after the air conditioner is powered up; controlling an air deflector rotatably installed at an air outlet of the air conditioner to restore according to the operation state, including, in response to the operation state being a turn- on state:
controlling the air deflector to restore to a restoration angle, the restoration angle being a maximum opening angle of the air deflector when opening to expose the air outlet; and
during rotation of the air deflector, controlling air output of the air conditioner according to a rotation angle of the air deflector, including:
while the air deflector rotates towards the restoration angle, in response to the rotation angle of air deflector being equal to or greater than an angle smaller than the restoration angle, controlling a fan of the air conditioner to start to output air while controlling the air deflector to continue to rotate towards the restoration angle; and

controlling the air deflector to adjust an air outlet angle according to an angle after restoration.

2 . The air conditioner control method of claim 1 , wherein:
the restoration angle is a first restoration angle; and controlling the air deflector to restore according to the operation state further includes:
controlling the air deflector to rotate to a second restoration angle in response to the operation state being a turn-off state, the second restoration angle being greater than or equal to a minimum closing angle of the air deflector required to close the air outlet.

3 . The air conditioner control method of claim 2 , wherein controlling the air deflector to adjust the air outlet angle according to the angle after restoration includes:
controlling the air deflector to rotate from the second restoration angle to a target air outlet angle after the air conditioner is turned on, the target air outlet angle being greater than the minimum closing angle.

4 . The air conditioner control method of claim 1 , wherein determining the operation state of the air conditioner includes:
determining a restoration state of the air deflector; and determining the operation state of the air conditioner in response to the restoration state being an unrestored state.

5 . The air conditioner control method of claim 4 , wherein determining the restoration state of the air deflector includes:
directly controlling the air deflector to adjust the air outlet angle according to the angle after restoration in response to the restoration state being a restored state.

6 . The air conditioner control method of claim 1 , wherein controlling the air deflector to adjust the air outlet angle according to the angle after restoration includes:
controlling the air deflector to rotate from the restoration angle to a target air outlet angle, the target air outlet angle being smaller than or equal to the maximum opening angle.

7 . A non-transitory computer-readable storage medium storing computer-executable instructions configured for implementation of the air conditioner control method of claim 1 .

8 . The air conditioner control method of claim 1 , wherein:
the air deflector is controlled to start to rotate towards the restoration angle at a first time; the air output of the air conditioner is controlled to start at a second time, the second time being later than the first time; and the air deflector arrives at the restoration angle at a third time, the third time being later than the second time.

9 . A control apparatus comprising:
a memory storing a computer program; and a processor configured to execute the computer program to:
determine an operation state of an air conditioner after the air conditioner is powered up;
control an air deflector rotatably installed at an air outlet of the air conditioner to restore according to the operation state, including, in response to the operation state being a turn-on state:
control the air deflector to restore to a restoration angle, the restoration angle being a maximum opening angle of the air deflector when opening to expose the air outlet; and
during rotation of the air deflector, control air output of the air conditioner according to a rotation angle of the air deflector, including:
while the air deflector rotates towards the restoration angle, in response to the rotation angle of air deflector being equal to or greater than an angle smaller than the restoration angle, controlling a fan of the air conditioner to start to output air while controlling the air deflector to continue to rotate towards the restoration angle; and

control the air deflector to adjust an air outlet angle according to an angle after the air deflector is restored.

10 . An air conditioner comprising:
an air outlet; an air deflector rotatably installed at the air outlet; and a control apparatus including: a memory storing a computer program; and a processor configured to execute the computer program to:
determine an operation state of the air conditioner after the air conditioner is powered up;
control the air deflector to restore according to the operation state, including, in response to the operation state being a turn-on state:
control the air deflector to restore to a restoration angle, the restoration angle being a maximum opening angle of the air deflector when opening to expose the air outlet; and
during rotation of the air deflector, control air output of the air conditioner according to a rotation angle of the air deflector, including:
while the air deflector rotates towards the restoration angle, in response to the rotation angle of air deflector being equal to or greater than an angle smaller than the restoration angle, controlling a fan of the air conditioner to start to output air while controlling the air deflector to continue to rotate towards the restoration angle; and

control the air deflector to adjust an air outlet angle according to an angle after the air deflector is restored.
