For example, they may be fixed connections or removable. Connected or connected integrally; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood in specific situations.

The present application provides an air conditioner, which includes an indoor unit having a first air outlet. The first air outlet is provided with a first swing leaf that can control the opening and closing range of the first air outlet. The first swing leaf is fully closed when the first air outlet is closed, and the first swing leaf is opened until the first air outlet has the largest amount of air; the first swing leaf is fully open; Between the closed state and the fully open state, it is defined as a free state; a controller is provided in the indoor unit, the controller includes a memory and a processor, wherein the memory stores a computer program, and the program is described by the When the processor executes, the following steps can be implemented: when the indoor unit is powered on, the first swing leaf runs to a fully open state to reset, and then runs to a fully closed state.

Although the swing leaves of the air outlet of the air conditioner are normally closed before the power is turned on, the swing position of the indoor unit is easily caused by the position and environment of the indoor unit. Changes, therefore, through the above-mentioned processing of increasing the swing leaves to reset to the fully open position and then closing them at the time of power-on, it is ensured that the swing leaves can be in the fully closed position after power-on is completed. In this process, the processing time from fully open to fully closed is generally about 10s. Therefore, the increase of this program will not cause excessive extension of the startup time. At the same time, the resetting process from fully open to fully closed ensures that when the air conditioner executes the swing leaf swing command, it can accurately realize the demand angle or demand position, and reduce the deviation of the demand position due to the different initial positions.

In addition, when shutting down, the first swing leaf of the first air outlet can only be in a fully closed state to prevent dust from entering and prevent people from accidentally touching the live parts and moving parts of the air conditioner. Therefore, when shutting down, the swing leaf should run to full Closed position, the fan motor also stops running at this time, but the operation of the fan will be delayed for a period of time. At this time, if the swing leaf is closed immediately, it will cause gambling wind and generate a lot of noise. Therefore, the above program is used by the processor. When executed, the following steps can be implemented: when the controller receives a shutdown signal, the first swing leaf is reset to a fully open state and runs to a fully closed state after a preset time. The preset time can be 5s, that is, when the controller receives the shutdown signal, the first swing leaf of the first air outlet is reset to the fully open position and waits for 5S before closing at the same time, thereby solving the problem of gambling during the residual operation of the fan. Phenomenon, greatly reducing noise.

In addition, the first swing leaf of the present application includes a plurality of the first swing leaf arranged one behind the other, and the first swing leaf at the rear is superimposed on the first swing leaf at the front when the first swing leaf is fully closed. When the program in the memory is executed by the processor, the following steps can be implemented: when the controller receives a start signal, the first swing leaf at the rear moves to the fully open position to reset, and the first swing leaf at the front resets After the preset time has elapsed, reset at the fully open position is performed.

The increase of the above procedure has the advantage that when the controller is turned on, multiple swing leaves are synchronized, and if the swing leaves are not fully closed before being turned on, it is easy to cause inaccurate stop positions of the swing leaves. By adding this procedure, the swing leaf is first reset to the fully open position, and then the swing leaf is stopped at the position required by the user controller, thereby avoiding the inaccuracy of the stop position of the wind deflector due to manual error. At the same time, because the front and rear swing leaves are fully closed, the rear swing leaves are pressed on the front swing leaves. At this time, if multiple swing leaves move at the same time, because the speed of the swing leaves is the same, there will be interference in the swinging process. The reaction causes the front and rear swing leaves to collide with each other, and setting the front swing leaves to wait for a preset time before performing the fully open action can effectively avoid mutual interference of the swing leaves. In the above, the preset time may be 1S.

At the same time, when the swing leaf performs the swing state, its rotation is generally controlled by a stepper motor, and the stepper motor loses some pulses when the direction of rotation is changed. Multiple swings will lose the pulse superposition, which will cause the swing of the swing leaves to be non-parallel. In the air conditioner of the present application, when the program in the memory is executed by the processor, the following steps can be implemented: when the controller receives a swing signal, the first swing leaf executes a swing action in accordance with a controller instruction Determining whether the number of swings of the first swing leaf is a preset number, and if so, controlling the first swing leaf to perform a fully open state reset, and recalculating the number of swings after the reset. The preset number of times can be 256 times. By limiting the preset number of times, the phenomenon that the swing leaves are not parallel after swinging due to how many different swing leaves lose pulses is effectively avoided.

The air conditioner of the present application may also have a second air outlet at the same time. Specifically, the indoor unit is provided with a second air outlet, and the second air outlet is provided with a first air outlet that can control the opening and closing range of the second air outlet. Two swinging leaves, the second swinging leaf is fully closed until the second air outlet is closed, the second swinging leaf is opened until the second air outlet has the maximum air flow, and the second swinging leaf is fully open A leaf is defined as a free state between a fully closed state and a fully open state. When the program in the memory is executed by the processor, the following steps can be implemented: when the controller receives a start signal, the second swing leaf runs to a fully open state; when the air conditioner executes a cooling mode, all the The second swing leaf runs to a fully closed state. Alternatively, when the program in the memory is executed by the processor, the following steps can be implemented: when the air volume of the air conditioner is lower than a preset air volume, the second swing blade runs to a fully closed state. Alternatively, when the program in the memory is executed by the processor, the following steps can be implemented: when the air conditioner runs for a preset time, the second swing leaf runs to a fully closed state. Alternatively, when the program in the memory is executed by the processor, the following steps can be implemented: when the controller receives a shutdown signal, the second swing leaf runs to a fully closed state. In the above three embodiments, the second swing blade can be operated to the fully closed state.

In addition, in addition to the above-mentioned improved structure in the air conditioner of the present application, other structures and connections between the structures are well known to those skilled in the art, such as the indoor unit is a wall-mounted type or a cabinet type; the first air outlet It is arranged on the upper part of the second air outlet, and there are two first swing leaves in the first air outlet, which are not described in detail here.

As shown in FIG. 1, the present application also provides a method for controlling an air conditioner, including the following steps:

It should be noted that when the air conditioner in this application swings freely, the automatic swinging state of the air conditioner is not limited to that it can only run from the fully open state to the fully closed state. It can also control the swing leaf to a certain degree according to a preset angle. Swing within range.

The above is only a specific implementation of this application, but the scope of protection of this application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in this application. It should be covered by the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
