The preset air outlet can be shielded only by the obstacles in the air sweeping range of the preset air outlet. Therefore, the distance sensor can only transmit the obstacle information in the wind sweeping range to the air conditioner, and the distance sensor can also detect the position information such as the distance, the azimuth (angle) and the like of the obstacle, transmit the position information to the air conditioner, and calculate the related information of the obstacle in the wind sweeping range by the air conditioner.

The air conditioner has a determined structure, the sweep angle range of the preset air outlet is fixed, so that the sweep range of the air outlet is fixed, a coordinate system can be established, the position of a specific point or a distance sensor on the preset air outlet is taken as an original point, the coordinate range of the sweep range is established on the coordinate system based on the wind speed of the preset air outlet and the sweep angle range of the preset air outlet, then, the position information of the obstacle is detected, the coordinate range of the obstacle on the coordinate system is determined based on the detected position information of the obstacle, the part of the obstacle, which is overlapped with the sweep range coordinate range, is further determined, and the overlapped part is the obstacle information in the sweep range.

Optionally, the sensing range of the distance sensor can be set and limited within the wind sweeping range, so as to obtain the obstacle information within the wind sweeping range.

The obstacle information is limited in the information of the obstacles in the wind sweeping range of the preset air outlet, so that the data primary screening can be completed in the data acquisition process, the judgment object is simplified, the excessive obstacles which cannot shield the preset air outlet are prevented from being brought into the subsequent judgment object, the program running resources are saved, and the judgment efficiency is improved, so that the air conditioner can respond quickly.

Step S20, judging whether the preset air outlet is shielded or not according to the obstacle information;

when the distance between the obstacle and the preset air outlet is smaller and the area of the obstacle is large enough, the preset air outlet can be shielded.

Optionally, when the distance between the obstacle and the preset air outlet is smaller than a certain value and the area of the obstacle is larger than a certain value, it is determined that the preset air outlet is blocked. Optionally, a corresponding relationship between the distance and the area is preset, the corresponding relationship may be in a list form, the area corresponding to each distance is listed, the corresponding relationship may also be in an expression form, that is, a mathematical formula form, and the corresponding area may be obtained through calculation based on the distance. When the distance between the obstacle and the preset air outlet is smaller than the first distance, determining an area threshold corresponding to the first distance, judging whether the area of the obstacle is larger than the area threshold, if so, judging that the preset air outlet is shielded, and if not, judging that the preset air outlet is not shielded. For example, the preset correspondence includes:

20cm-8cm²、40cm-12cm²、60cm-16cm²when the distance between the obstacle and the preset air outlet is 20cm, the area of the obstacle is more than or equal to 8cm²And when the air is blocked, the preset air outlet is judged.

And step S30, when the preset air outlet is shielded, closing the preset air outlet.

When the preset air outlet is blocked, most of the wind coming out of the preset air outlet may act on the barrier, so that the wind quantity acting on the indoor air is reduced, and energy loss is caused. Therefore, the shielded air outlet is closed, so that the air in the air conditioner enters the room from the unshielded air outlet, and unnecessary energy loss is reduced.

Optionally, step S30 is followed by: and counting the continuous times of closing the preset air outlet, and setting a closing label when the continuous times are more than the preset times so that the air conditioner can read the closing label and directly close the preset air outlet when being started next time without executing the related judgment of the steps S10-S30. Alternatively, the close tag may be automatically cancelled after a preset period of time, or the tag may be cancelled after receiving a cancel instruction.

Because of wall-hanging air conditioner mounted position is fixed, predetermine being sheltered from the condition of air outlet and probably can not changing for a long time, through the continuous number of times of closing predetermineeing the air outlet, the distinguishable air conditioner is fixed mounting, predetermines the situation that the air outlet is sheltered from and probably can not change in the short time, therefore, close the label through setting up, can save unnecessary judgement, directly close predetermineeing the air outlet, save air conditioner operating resources.

Optionally, the obstacle information includes a distance between the obstacle and the preset air outlet and an area of the obstacle, as shown in fig. 3, where the step S20 includes:

step S21, when the distance between the obstacle and the preset air outlet is smaller than a first preset distance, acquiring an area threshold value corresponding to the distance between the obstacle and the preset air outlet;

and step S22, when the area of the obstacle is larger than or equal to the area threshold, judging that the preset air outlet is blocked.

The distance between the obstacle and the preset air outlet refers to the distance between the obstacle in the wind sweeping range of the preset air outlet and the specific position of the preset air outlet, such as the distance between the obstacle and a certain wind guide blade of the preset air outlet or the distance between the obstacle and the center of an upper shell of the preset air outlet. Optionally, the distance between the obstacle and the preset air outlet may be the closest distance between the obstacle and the preset air outlet, the distance between the obstacle and the plurality of distance collecting points is determined by setting the plurality of distance collecting points on the preset air outlet, and the minimum distance is taken as the distance between the obstacle and the preset air outlet, where the distance collecting points may be set on the edge of the preset air outlet and/or the air guide blade.

When the distance between the barrier and the preset air outlet is larger, the barrier has small shielding effect on the preset air outlet, and the influence of the barrier on the action efficiency of the air conditioner is not required to be considered; when the distance between the barrier and the preset air outlet is small, the barrier has a large shielding effect on the preset air outlet, and the influence of the barrier on the action efficiency of the air conditioner needs to be considered. The first preset distance is a distance threshold preset in the air conditioner, and only when the distance between the barrier and the preset air outlet is smaller than the distance threshold, the subsequent judgment on whether the preset air outlet is blocked needs to be further carried out. If the distance between the barrier and the preset air outlet is larger than or equal to the first preset distance, the preset air outlet is judged not to be shielded.

The smaller the distance between the barrier and the preset air outlet is, the smaller the area of the barrier required by the same shielding effect on the preset air outlet is. Therefore, the corresponding relation between the distance between the obstacle and the preset air outlet and the area of the obstacle can be preset, and the corresponding relation can be in a list form and records the mapping relation between each distance interval and the area of the obstacle.

After confirming that the distance between the barrier and the preset air outlet is smaller than the first preset distance, determining a corresponding area threshold value based on the distance interval where the distance between the barrier and the preset air outlet is located, when the area of the barrier is larger than the area threshold value, showing that the barrier is not only close to the preset air outlet, but also has a larger area, and can have a larger shielding effect on the preset air outlet, at the moment, judging that the preset air outlet is shielded.

Optionally, if the area of the obstacle is smaller than the area threshold, it is described that the obstacle is close to the preset air outlet, but the area of the obstacle is small, so that the shielding effect on the preset air outlet is limited, and at this time, it can be determined that the preset air outlet is not shielded.

The size of the shielding effect of the barrier on the preset air outlet is judged through the distance between the barrier and the preset air outlet and the area size of the barrier, so that whether the preset air outlet is shielded or not is judged, the shielding situation of the preset air outlet can be effectively judged, the opening and closing of the preset air outlet are determined, and the effect efficiency of the air conditioner is ensured.

Alternatively, as shown in fig. 4, step S21 is followed by:

step S23, when the area of the obstacle is smaller than the area threshold, controlling the preset air outlet to adjust the air supply angle so as to avoid the obstacle;

when the area of the obstacle is smaller than the area threshold value, the obstacle is close to the preset air outlet, but the area of the obstacle is not large, if the preset air outlet is directly judged to be blocked, the preset air outlet is closed, the preset air outlet is not fully utilized, the air supply range of the air conditioner is reduced, the action range of the air conditioner is reduced, the obstacle is avoided by adjusting the air supply angle of the preset air outlet, the 'acting' on the obstacle can be avoided, the situation that air conveyed by the preset air outlet is blocked by the obstacle and the air is not smooth in flow can be avoided, the preset air outlet can be fully utilized, and the wider action range of the air conditioner is ensured.

Alternatively, as shown in fig. 5, step S21 is followed by:

and step S24, when the area of the obstacle is smaller than the area threshold and is larger than or equal to a first preset area, controlling the preset air outlet to adjust the air supply angle to avoid the obstacle, wherein the area threshold is larger than the first preset area.

When the area of the obstacle is smaller than the first preset area, the area of the obstacle is very small, at the moment, no matter how close the obstacle is to the preset air outlet, even if the obstacle is attached to the preset air outlet, the shielding effect of the obstacle on the preset air outlet is not too large, therefore, when the area of the obstacle is smaller than the area threshold value, whether the area of the obstacle is larger than or equal to the first preset area or not is further judged, if the area of the obstacle is smaller than the first preset area, the obstacle still has a certain shielding effect on the preset air outlet, at the moment, the air supply angle of the preset air outlet needs to be adjusted to avoid the obstacle, the influence of the obstacle on the air conditioner is reduced to the minimum, if the area of the obstacle is smaller than the first preset area, the air supply angle does not need to be adjusted to avoid the obstacle, and the air conditioner can be controlled according to the normal operation of the air conditioner. Therefore, the shielding effect of the barrier on the preset air outlet can be further accurately identified to determine whether the air supply angle is adjusted for avoiding the barrier, and the air conditioner is ensured to have better effect efficiency and effect range.

Optionally, the controlling the preset air outlet to adjust the air supply angle and avoid the obstacle includes: determining the relative position relationship between the barrier and the preset air outlet; determining a target air supply angle based on the relative position relation; and controlling the preset air outlet to supply air at the target air supply angle.

In order to accurately describe the relative position relationship between the barrier and the preset air outlet, the wind sweeping range of the preset air outlet can be subdivided. In an embodiment, the preset air outlet can sweep air up and down or can sweep air left and right, so that the air sweeping range of the preset air outlet is divided into nine areas, namely, upper left area, lower left area, middle left area, upper right area, lower right area, middle right area, upper right area, lower right area and the like, and the obstacle is located in at least one of the nine areas.

The target air supply angle is an angle capable of avoiding the obstacle, for example, when the obstacle is at the upper left position of the preset air outlet, the target air supply angle may be any other angle than the upper left direction.

Specifically, based on the relative position relationship between the obstacle and the preset air outlet, the selectable range of the target air supply angle can be determined first, and then the final target air supply angle is determined based on the normal operation requirement of the air conditioner. For example, when the obstacle is at the upper left position of the preset air outlet, the selectable range of the target air supply angle is any angle other than the upper left direction, at this time, the normal operation requirement of the installation air conditioner needs to set the air supply angle of the preset air outlet to be positive, and the target air supply angle is the middle.

The target air supply angle capable of avoiding the obstacle is determined according to the relative position relation between the obstacle and the preset air outlet, so that air conveyed by the preset air outlet can smoothly enter indoor air, the adjusting range of the air conditioner is widened, and certain adjusting efficiency is guaranteed.

Optionally, the determining a target air supply angle based on the relative position relationship includes at least one of:

when the relative position relation is that the barrier is positioned above the preset air outlet, the target air supply angle is an angle for supplying air towards the front or the lower direction;

when the relative position relation is that the barrier is positioned below the preset air outlet, the target air supply angle is an angle for supplying air towards the front or the upper direction;

when the relative position relation is that the barrier is located at the middle upper position of the preset air outlet, the target air supply angle is an angle for supplying air downwards;

when the relative position relation is that the barrier is positioned at the middle lower position of the preset air outlet, the target air supply angle is an upward air supply angle;

and when the relative position relation is that the barrier is positioned above and below the preset air outlet, the target air supply angle is an angle towards the front.

The air conditioner is provided with an upper position, a lower position and/or an angle range corresponding to the middle position, and the relative position of the obstacle relative to the preset air outlet is determined based on the angle of the obstacle relative to the preset air outlet.

By setting the determination rule of the target air supply angle in the air conditioner, the air conditioner can determine the corresponding relation between the position of the obstacle and the preset air outlet avoiding angle, so that the preset air outlet can smoothly avoid the obstacle, and the air conditioning efficiency of the air conditioner is ensured.

Optionally, as shown in fig. 6, after step S21, the method further includes:

step S25, when the area of the obstacle is smaller than the area threshold, determining the relative position relation between the obstacle and the preset air outlet;

and step S26, when the relative position relation is that the barrier is at the middle-upper position of the preset air outlet and the air conditioner is in a refrigeration running mode, judging that the preset air outlet is shielded.

In the refrigerating state of the air conditioner, when the air outlet is upward or horizontally blown, the cold air sinks to achieve a better effect of reducing the room temperature. Therefore, when the area of the obstacle is smaller than the area threshold value, the relative position relation between the obstacle and the preset air outlet is determined, if the air conditioner is in a refrigeration running mode, the obstacle is just above the middle position of the preset air outlet, namely cold air blown out from the preset air outlet cannot be blown upwards or horizontally, the preset air outlet is judged to be blocked, the preset air outlet is closed, and air generated by the preset air outlet corresponding to the fan is blown upwards or horizontally from the unblocked air outlet, so that the expected refrigeration effect is achieved.

The air outlet is required to be preset at a certain angle for ensuring the refrigeration effect, and when the barrier shields the air outlet, the air outlet can be directly closed and preset, so that the air which flows out of the preset air outlet is blown upwards or horizontally from other air outlets to ensure the better refrigeration effect.

Optionally, after step S21, the method further includes:

when the area of the obstacle is smaller than the area threshold, determining the relative position relation between the obstacle and the preset air outlet; and when the relative position relation is that the barrier is positioned below the preset air outlet and the air conditioner is in a heating operation mode, judging that the preset air outlet is shielded.

In the heating state of the air conditioner, the air outlet blows downwards, and the effect of improving the room temperature is achieved through the rising of hot air. Therefore, when the area of the obstacle is smaller than the area threshold value, the relative position relation between the obstacle and the preset air outlet is determined, if the air conditioner is in the heating operation mode and the obstacle is just below the preset air outlet, the preset air outlet is judged to be shielded, and the preset air outlet is closed. The air generated by the preset air outlet corresponding to the fan is blown downwards from the air outlet which is not shielded, so that the expected heating effect is achieved.

Alternatively, after determining the sweep angle based on the above embodiments, if the air blowing angle needs to be adjusted according to other control of the air conditioner, the steps S10-S30 are executed again, that is, the obstacle information is determined again, and then it is determined whether the air blowing angle is adjusted.
