Background
In order to realize the comfort of the air conditioner and solve the problem of condensation in the operation of the air conditioner, the air outlets of the traditional wall-mounted air conditioner are not completely closed. Even some air deflectors which form a fully-closed appearance at the air outlet are complex in movement mechanism mode and large in occupied space. In addition, due to the limitation of the rotation of the single air guide plate, the air supply comfort of the air conditioner cannot be fully realized. Therefore, in order to achieve air supply comfort, the air conditioner is provided with the double air guide plates, the opening and closing directions of the double air guide plates are controlled to be consistent, although the air supply problem is solved, in order to ensure that the double air guide plates form full-closed sealing at the air outlet, the movement gap between the two air guide plates is small, the gap is likely to generate thermal deformation after the air guide plates and the air duct are locally heated for a long time after being shut down in a heating state, one air guide plate can be locally arched and deformed, the other air guide plate can be locally deformed when being laid down, so that the movement gap between the two air guide plates is reduced, even in the state that the air outlet is closed, the gap allowance between the two air guide plates is already eaten, and the interference phenomenon occurs. If the air deflectors are continuously closed, the phenomenon that the two air deflectors are blocked in the closing process can be caused, the closing abnormal sound condition can be generated, the straight state can be recovered only after the air deflectors and the air opening are fully cooled, the movement gap can be recovered between the two air deflectors, and therefore the air deflectors can be normally closed. If the air guide plate is restarted, the two air guide plates cannot be normally opened due to interference.

and if the current temperature is greater than or equal to the preset temperature, controlling the two air deflectors to keep for a first preset time in the current state, and then controlling one or more of the two air deflectors to move to a closed position.
The current state is that one air deflector is in a closed position and the other air deflector is in a position to be closed, and a gap is formed between the two air deflectors in the current state.
And the current temperature is the temperature of the heat exchange tube in the second preset time before the air conditioner indoor unit is shut down.

Detailed Description
Fig. 1 to 4 illustrate an opening process of the first and second wind deflectors, and fig. 7 to 10 illustrate a closing process of the first and second wind deflectors. As shown in fig. 1, in the air conditioner provided in the embodiment of the present invention, the air conditioner includes an air conditioner indoor unit, two air deflectors are disposed at an air outlet 10 of the air conditioner indoor unit, both of the two air deflectors are rotatable to open and close the air outlet, and the two air deflectors are a first air deflector 20 and a second air deflector 30, respectively. The two air deflectors can be driven by gears, connecting rods, racks and the like.
As shown in fig. 1, before the air conditioner is turned on, the first air deflector 20 and the second air deflector 30 are both in the closed position, and the air outlet 10 of the indoor unit of the air conditioner is closed. As shown in fig. 2, after the indoor unit of the air conditioner is started, the second air guiding plate 30 rotates clockwise, so that the left end of the second air guiding plate 30 touches the positioning notch of the left sidewall of the air outlet 10 (the rotation angle is about 20 °), and a gap 40 with a size of more than 4.5mm is formed between the left end of the first air guiding plate 20 and the right end of the second air guiding plate 30, so that the two air guiding plates move conveniently. As shown in fig. 3, after a gap is formed between the first air deflector 20 and the second air deflector 30, the first air deflector 20 starts to rotate clockwise until the left end of the first air deflector 20 contacts the right sidewall of the air outlet 10 (i.e., the first air deflector 20 moves to the maximum opening position), and as shown in fig. 4, the second air deflector 30 starts to rotate counterclockwise until the first air deflector 20 and the second air deflector 30 reach a parallel state. The sequential rotation sequence in the process is that the first air deflector and the second air deflector do not interfere with each other in the rotation process so as to make up for the rotation space. If the opening speed of the air guide plates is increased, the second air guide plate can rotate along with the first air guide plate when the first air guide plate rotates to a certain non-interference angle, and the second air guide plate does not need to rotate until the left end of the first air guide plate contacts with the right side wall of the air outlet.
The rotating angles of the two air deflectors in the opening process are not fixed, and the proper rotating angles can be adjusted according to the structure, so that the first air deflector and the second air deflector are in a non-interference state without being limited to the angles.
As shown in fig. 5, when the first air guiding plate 20 and the second air guiding plate 30 are parallel and in an inclined state, the two air guiding plates are combined to form an optimal heating state, and in this state, the hot air flow is blown out obliquely downwards, so that the landing effect is good, the hot air flow is blown farther after landing, and the heating comfort is improved. As shown in fig. 6, when the first air guiding plate 20 and the second air guiding plate 30 are parallel and in a horizontal state, the state is an optimal cooling state, so that the cooling comfort of the air conditioner is improved, and the effect of preventing people from blowing is achieved.
Under the optimal heating state and the optimal cooling state, when the first air deflector and the second air deflector keep parallel up-and-down rotation at the same rotating speed, the air conditioner can enter the up-and-down air sweeping state, and the distance of air flow blowing can be adjusted.
As shown in fig. 7, after the air conditioner is turned off, the first air deflector 20 rotates clockwise, so that the left end of the first air deflector 20 contacts the right sidewall of the air outlet 10 (i.e., the first air deflector 20 moves to the maximum opening position). As shown in fig. 8, after the first air guiding plate 20 moves to the maximum opening position, the second air guiding plate 30 rotates clockwise, so that the left end of the second air guiding plate 30 contacts with the positioning notch of the left sidewall of the air outlet 10 (this position is the position to be closed of the second air guiding plate 30). As shown in fig. 9, after the second air guiding plate 30 moves to the position to be closed, the first air guiding plate 20 rotates counterclockwise to the closed position, and at this time, a gap of more than 4.5mm is formed between the left end of the first air guiding plate 20 and the right end of the second air guiding plate 30. As shown in fig. 10, in the state of fig. 9, the second air guiding plate 30 is rotated counterclockwise to the closing position, and the two air guiding plates are closed, thereby closing the air outlet.
When the two air deflectors are in the closed position, the first air deflector is provided with a first closed surface facing the second air deflector, the second air deflector is provided with a second closed surface facing the first air deflector, the first closed surface is in contact with the second closed surface, seamless sealing of the air outlet is achieved, and the overall appearance effect of the indoor unit is improved.
As shown in fig. 11, in order to avoid the problem that the two air deflectors are deformed by heat in the heating state, so that the two air deflectors are closed and interfered after the air conditioner is turned off, the present invention provides a control method for an air conditioner indoor unit, the control method comprising:

The current state is that neither air deflector is in the closed position or only one of the air deflectors is in the closed position. In this embodiment, the current state is that the first air guiding plate is in the closed position and the second air guiding plate is in the position to be closed, when the first air guiding plate is in the closed position, the right end of the first air guiding plate contacts with the right side wall at the air outlet, and a gap is formed between the two air guiding plates in the current state.

Therefore, the two air deflectors are required to be cooled for 5 minutes under the current state to restore to be straight, and the two air deflectors are closed after being deformed and restored, so that interference is avoided.
In this embodiment, the current temperature is the temperature of the heat exchange tube in the second preset time before the indoor unit of the air conditioner is turned off. In this embodiment, the second preset time is 10 minutes, a temperature sensing bulb is arranged in the air conditioner indoor unit, and the temperature of the heat exchange tube is detected through the temperature sensing bulb.
If the current temperature is lower than the preset temperature (namely the current temperature is lower than the preset temperature), the indoor unit of the air conditioner is judged to be in a refrigerating state before being shut down, and the two air deflectors or one of the two air deflectors is directly controlled to move to a closing position, so that the air outlet is closed.
