If the target air outlet direction is lower air outlet and the current air outlet direction is side air outlet, determining that the wind direction switching condition is changed from side air outlet to lower air outlet. If the target air outlet direction is the side air outlet and the current air outlet direction is the lower air outlet, determining that the switching condition of the air direction is changed from the lower air outlet to the side air outlet. In this way, based on the comparison of the target air outlet direction and the current air outlet direction, whether the air direction needs to be switched or not is determined, and when the air direction needs to be switched, the specific switching direction is determined. So as to precisely control the rotation of the scroll casing.

Optionally, S1322, the air conditioner determines a target position of the volute according to a switching condition of the wind direction, including:

and under the condition that the side air outlet is switched to the lower air outlet, the air conditioner determines the target position of the volute to be the second position.

In the case of switching from the lower air outlet to the side air outlet, the air conditioner determines the target position of the volute as the first position.

As described above, when the scroll case is located at the first position, the side air outlet of the air conditioner corresponds to the side air outlet. When the volute is positioned at the second position, the volute corresponds to lower air outlet of the air conditioner. Because the air outlets of the air conditioner are a side air outlet and a lower air outlet respectively, the wind direction is also switched between the side air outlet and the lower air outlet. And if the side air outlet is switched to the lower air outlet, determining the target position of the volute as a second position. And if the lower air outlet is switched to the side air outlet, determining the target position of the volute as a first position. Thus, the target position of the volute corresponds to the target air outlet direction, so that the normal air supply of the air conditioner is realized.

Optionally, as shown in conjunction with fig. 15, another method for controlling an air conditioner is provided according to an embodiment of the present disclosure, including:

S1313, controlling the sealing baffle to rotate towards the direction of attaching the volute when the target position of the volute is different from the current position of the volute.

S1323, the air conditioner controls the volute to rotate to the target position of the volute.

S1333, the air conditioner controls the sealing baffle to rotate to the target position of the sealing baffle.

As previously described, the target position of the volute is either the first position or the second position. The first position and the second position correspond to the side air outlet and the lower air outlet. If the target air outlet direction is inconsistent with the current air outlet direction, the target position of the volute is correspondingly inconsistent with the current position. The sealing baffle can rotate relative to the volute. When the sealing baffle rotates to one side far away from the volute, the sealing baffle is in an open state. When the sealing baffle rotates to a position which is attached to the outer wall of the volute, the sealing baffle is in a retracted state. When the volute is fixed at the target position of the volute for supplying air, the sealing baffle is in an open state so as to seal the second air port, and air leakage is reduced. When the volute rotates, the sealing baffle needs to be retracted to avoid blocking the rotation of the volute. Therefore, when the rotation of the volute and the sealing baffle is controlled, the sealing baffle is controlled to retract, and then the rotation of the volute is controlled. And after the volute rotates to the target position, controlling the sealing baffle to be opened to the target position of the sealing baffle. Like this, not only realized the switching of air-out direction through the rotation of control spiral case, but also through the rotatory opportunity of control sealing baffle and spiral case, can also avoid sealing baffle to cause the hindrance to the rotation of spiral case. Thereby ensuring the effective switching of the air outlet direction. It should be noted that, the specific implementation procedures of steps S1301, S1312, S1322 and S1304 are described in the above embodiments, and are not repeated here.

Optionally, there are two target positions of the sealing barrier. When the target position of the volute is the first position, the target position of the sealing baffle is the third position. When the sealing baffle is positioned at the third position, the bottom of the sealing baffle is abutted against the first edge of the second air port. At this time, the sealing baffle separates first wind gap and second wind gap, also separates the air outlet and the second wind gap of spiral case simultaneously, prevents that the air-out of spiral case from leaking out from the second wind gap. So as to ensure the air supply effect of the air conditioner.

When the target position of the volute is the second position, the target position of the sealing baffle is the fourth position. When the sealing baffle is positioned at the fourth position, the side surface of the sealing baffle is abutted against the second edge. At this time, the left side of the volute air outlet is abutted against the first edge. After being matched with the sealing baffle, the air outlet of the volute can be completely sent out from the second air inlet as much as possible, and the air quantity flowing back into the housing is reduced. Thereby ensuring the air supply effect of the air conditioner.

Optionally, S1304, the air conditioner controls the filter screen to move according to the target position of the volute, including:

and under the condition that the target position of the volute is the first position, the air conditioner control filter screen moves to a position exposing the first air port and shielding the second air port.

And under the condition that the target position of the volute is the second position, the air conditioner control filter screen moves to a position where the first air port is shielded and the second air port is exposed.

From the above, the filter screen has a certain flexibility. Thus, the screen may be rolled up. This allows for control of the movement of the filter screen between the first and second ports. If the target position of the volute is the first position, the first air port is used as an air outlet, and the second air port is used as an air inlet. The rotary shaft of the filter assembly is controlled to rotate clockwise, so that the rotary shaft drives the filter screen to move downwards. The filter screen exposes the first air port and simultaneously shields the second air port. If the target position of the volute is the second position, the second air port is used as an air outlet, and the first air port is used as an air inlet. The rotary shaft of the filter assembly is controlled to rotate anticlockwise, so that the rotary shaft drives the filter screen to move upwards. The filter screen is enabled to shield the first air opening and expose the second air opening. Optionally, the driving device drives the rotating shaft to rotate. Thus, the control filter screen shields the air inlet, and dust entering the indoor unit can be reduced. The control filter screen exposes the air outlet, can avoid blowing in indoor with the dust on the filter screen, can also guarantee the air outlet's of air outlet simultaneously.

Optionally, S1323, the air conditioner controls the scroll casing to rotate to a target position of the scroll casing, including:

the air conditioner determines a target rotation direction of the scroll case.

The air conditioner controls the volute to rotate a second angle towards the target rotation direction of the volute.

And determining the target rotation direction of the volute according to the target position of the volute. When the target position of the scroll case is the first position, the target rotation direction of the scroll case is determined to be upward rotation, i.e., clockwise rotation. When the target position of the scroll case is the second position, the target rotation direction of the scroll case is determined to be rotated downward, i.e., rotated counterclockwise. After the target rotation direction of the volute is determined, the volute is controlled to rotate by a second angle beta towards the determined target rotation direction. Since the first position and the second position are unchanged, the rotation angle of the scroll case is the first angle regardless of whether the scroll case is rotated from the first position to the second position or from the second position to the first position. In this way, the target rotation direction of the volute is determined first, and the path (or angle) the volute rotates is minimized as far as possible, so that the volute rotates to a proper air outlet position quickly. And then controlling the spiral case to rotate by a second angle so as to accurately control the rotation stop position of the spiral case and reduce the occurrence of the problem that the spiral case is not rotated in place or is excessively rotated.

Optionally, S1333, the air conditioner controls the sealing barrier to rotate to a target position of the sealing barrier, including:

the air conditioner determines a target rotation direction of the sealing barrier.

And when the target position of the sealing baffle is the third position, the air conditioner controls the sealing baffle to rotate by a first angle towards the target rotation direction of the sealing baffle.

The air conditioner controls the sealing baffle to rotate a third angle towards the target rotation direction of the sealing baffle under the condition that the target position of the sealing baffle is a fourth position; wherein the second angle is greater than the first angle and the first angle is greater than the third angle.

The target position of the scroll case corresponds to the target position of the sealing damper. Thus, the target rotational position of the sealing barrier can be determined from the target position of the volute. The sealing barrier needs to be opened to rotate to the target position.

If the target position of the volute is the first position, the target position of the sealing barrier is the third position. The target rotation direction is left rotation, i.e. clockwise rotation. The sealing barrier is controlled to rotate clockwise by a first angle a. If the target position of the volute is the second position, the target position of the sealing barrier is the fourth position. Its target rotation direction is rotated downward, i.e., clockwise. The sealing barrier is controlled to rotate clockwise by a third angle gamma. In this way, the target rotation direction of the sealing barrier is determined first, so that the sealing barrier is in an open state, and the sealing barrier is rotated in the rotation direction, so that the sealing barrier can seal the second tuyere. Then control spiral case rotation suitable angle to the rotatory stop position of accurate control sealing baffle avoids sealing baffle to rotate and can appear the problem of air leakage in place, in order to guarantee the stability of air supply.

Since the first air port and the second air port are positioned on different sides of the shell, the second angle beta of the rotation of the volute is larger when the air outlet direction is switched. When the volute rotates to the first position, the rotating point of the sealing baffle plate is far away from the second air opening. Therefore, in order to seal the second tuyere, the sealing flap needs to be rotated by a larger first angle α, but not exceeding the second angle β. When the volute rotates to the second position, the rotating point of the sealing baffle plate is closer to the second air opening. Therefore, the sealing baffle plate can seal the second air port only by the third angle gamma with smaller rotation angle. Thus, β > α > γ. Alternatively, α ε [40 °,60 ° ], β ε [69 °,89 ° ], γ ε [5 °,25 ° ]. The specific values of alpha, beta and gamma can be selected according to actual needs.

Optionally, as shown in conjunction with fig. 16, another method for controlling an air conditioner is provided according to an embodiment of the present disclosure, including:

S1305, the air conditioner determines a target air port according to the target air outlet direction.

S1306, the air conditioner controls the angle of each transverse air deflector according to the target air port.

And determining a target air outlet based on the determined target air outlet direction. The target air port is an air outlet, and the non-target air port is an air inlet. If the target air outlet direction is the side air outlet, the target air outlet is the first air outlet (side air outlet). If the target air outlet direction is lower air outlet, the target air outlet is a second air outlet (lower air outlet). When the air conditioner operates, the first transverse air guide plate and the second transverse air guide plate are all opened to the maximum angle so as to ensure maximum air inlet and maximum air outlet. Optionally, the angle change of the transverse air deflector at the target air port can be controlled according to the air supply requirement of a user so as to realize swing air supply or air supply in a specific direction. In principle, however, the transverse air deflector at the non-target tuyere is controlled to always maintain a maximum angle to ensure maximum air intake. Optionally, the maximum angles of the first transverse air deflector and the second transverse air deflector are: when the transverse air deflector is parallel to the air inlet direction, the angle of the transverse air deflector is formed. It should be noted that, the specific implementation procedures of steps S1301, S1312, S1322 and S1304 are described in the above embodiments, and are not repeated here.

The process of controlling the scroll, sealing baffle and filter screen will be described in detail as follows:

case one: as shown in fig. 1, the current air outlet direction is the side air outlet, and the target air outlet direction is the lower air outlet. At this time, the volute is located at the first position; the sealing baffle is positioned at a third position; the filter screen exposes the first air port and shields the second air port. The target position of the volute is a second position; the target position of the sealing barrier is the fourth position.

As shown in fig. 1 and 2, the sealing baffle is controlled to rotate anticlockwise by a first angle alpha, so that the sealing baffle is attached to the outer wall of the volute. Then, as shown in fig. 2 and 3, the scroll is controlled to rotate counterclockwise by a second angle β, so that the scroll is rotated to a second position. At this time, the air outlet of the volute corresponds to the air outlet of the lower air port, and the left side of the air outlet of the volute is abutted with the first edge of the air outlet of the lower air port. Then, as shown in fig. 3 and 4, the sealing baffle is controlled to rotate clockwise by a third angle gamma so that the side surface of the sealing baffle is abutted against the second edge of the air outlet. And controlling the filter screen to shield the first air port and expose the second air port.

And a second case: as shown in fig. 4, the current air outlet direction is the lower air outlet, and the target air outlet direction is the side air outlet. At this time, the volute is located at the second position; the sealing baffle is positioned at a fourth position; the filter screen shields the first air port and exposes the second air port. The target position of the volute is a first position; the target position of the sealing barrier is the third position.

As shown in fig. 4 and 3, the sealing baffle is controlled to rotate anticlockwise by a third angle gamma, so that the sealing baffle is attached to the outer wall of the volute. The scroll is then controlled to rotate clockwise through a second angle beta as shown in fig. 3 and 2, causing the scroll to rotate to the first position. At this time, the air outlet of the volute corresponds to the side air outlet. Then, as shown in fig. 2 and 1, the sealing baffle is controlled to rotate clockwise by a first angle alpha, so that the bottom of the sealing baffle is abutted against the first edge of the lower tuyere.

Thereby controlling the volute to rotate to a target position so as to realize the air outlet of the air conditioner from the first air outlet or the second air outlet. By utilizing the rotation of the volute, the change of the air outlet direction can be realized. The air outlet of the volute can smoothly pass through the corresponding air port without changing the flow path. Moreover, based on the target position of the volute, the sealing baffle is controlled to rotate adaptively, so that the phenomenon of air leakage can be reduced. Thus, the stability and uniformity of the air flow of the air outlet are improved, and the purpose of improving the air supply effect is achieved.
