By the control method, the inclination angle of the air deflector can be adjusted according to the current gear of the fan, so that the direction of air flow entering the air conditioner from the air inlet can be adjusted as required. The air deflector enables the air current to prerotate at the air inlet, so that the air current enters the air conditioner at a proper angle, the disorder degree of the air current is reduced, the noise is reduced, and meanwhile, the smooth air current is also beneficial to reducing the energy consumption of the fan. In addition, the air inlet angle of the air conditioner is reasonably selected, so that the distribution of air flow on the heat exchange assembly is more uniform, and the heat exchange efficiency is improved. Therefore, in general, the proper air inlet angle is adjusted according to the current gear of the fan, and the running state of the air conditioner is favorably improved.
In an optional embodiment, each gear of the fan corresponds to a preset inclination angle of the air deflector, and the driving member is controlled to adjust the inclination angle of the air deflector according to the gear of the fan, which specifically includes:
determining a preset inclination angle of the air deflector corresponding to the current gear of the fan as a target inclination angle of the air deflector according to the corresponding relation between each gear of the fan and each preset inclination angle of the air deflector;
calculating the corresponding rotation angle of the air deflector according to the target inclination angle of the air deflector and the current inclination angle of the air deflector;
the driving piece is controlled to drive the air deflector to rotate by a corresponding rotation angle.
The method is characterized in that the inclination angle of an air deflector is correspondingly preset for each gear of the fan, and when the air deflector needs to be adjusted according to a windshield each time, a driving piece is controlled to drive the air deflector to rotate according to the corresponding inclination angle and the current inclination angle of the air deflector, so that the method is feasible and efficient. When the gear of the fan is fixed, the air deflector has a better inclination angle, so that the inclination angle is preset, and when the fan runs at a certain gear, the air deflector is directly adjusted to the preset inclination angle.

Then, in the actual operation process of the air conditioner, when the fan operates at a certain gear, the inclination angle of the air deflector is adjusted to the corresponding preset inclination angle, so that the air conditioner can be ensured to have a better operation state under different fan gears in the actual operation process.

The current gear may also be determined according to an instruction input by a user. The target gear of the fan is included in the command, and the target gear is determined as the current gear, so that the step of actual measurement is saved, the interference possibly faced in the actual measurement process is not needed to be overcome, and the method is a stable gear determining mode.
In an alternative embodiment, the control method of an air conditioner further includes:
and controlling the driving piece to drive the air deflector to close the air inlet according to the shutdown instruction.

In the former method, a shutdown instruction is received as a trigger condition, and once the shutdown instruction is received, the rotating speed of the fan is gradually reduced, and the air deflector is also synchronously closed. This makes synchronization efficient. The latter mode returns the rotating speed of the fan to zero as a trigger condition, and closes the air inlet when the rotating speed of the fan returns to zero, thereby being beneficial to avoiding stronger negative pressure generated in the air conditioner.

Detailed Description
After the fan operates, airflow enters the shell from the air inlet, passes through the heat exchange assembly and the fan, and is discharged from the air outlet. The air inlet structure of the air conditioner in the prior art is fixed, and when the fan runs, the angle of air flow entering from the air inlet is not adjustable. When some current air conditioners operate, due to the fact that the air inlet angle is not reasonable enough, airflow flow fields on a path from an air inlet to a fan are unreasonable, airflow is disordered, and noise is large; even the distribution relation of the airflow relative to the heat exchange assembly is not reasonable enough, so that the heat exchange efficiency is not high. In the prior art, some air conditioners are additionally provided with air deflectors, and the air deflectors can pre-rotate airflow before the airflow enters the air conditioner, so that airflow disorder is reduced. However, the existing air deflector is fixed, and the guiding direction of the air deflector to the air flow cannot be adjusted. The inclination angle of the air deflector suitable for one gear (which can affect the flow guiding direction) may no longer be suitable for another gear. Therefore, the fixed air deflector cannot meet the requirements of diversion in different gears, and in one gear, the air conditioner has a better operation state due to the diversion effect of the air deflector, but in the other gear, the air deflector cannot keep the air conditioner in a better operation state (such as higher noise, lower heat exchange efficiency and the like).
Therefore, the air conditioner and the control method thereof can realize that the inclination angle of the air deflector changes along with the gear of the fan, so that the running state of the air conditioner is always maintained at a better level. In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below.
Fig. 1 is a schematic front view of an air conditioner 010 according to an embodiment of the present application; fig. 2 is a schematic diagram of a rear surface of the air conditioner 010 according to an embodiment of the present invention. Referring to fig. 1 and 2, an air conditioner 010 of the present embodiment is a wall-mounted indoor unit, and includes a casing 100, a human-computer interaction device 300, a heat exchange assembly (not shown), a fan 200, and a controller 400 disposed in the casing 100. As shown in the drawings, the case 100 includes a middle frame 110, two end caps 130, a front panel 120, and a hanging panel 140. The middle frame 110 functions as a frame, and the front panel 120 is disposed at a front side of the middle frame 110, that is, a side facing a user under normal trial use. The hanging plate 140 is disposed at the rear side of the middle frame 110, i.e., at a side close to the wall surface in normal use, and the hanging plate 140 is provided with a mounting hole and the like, so that the air conditioner 010 can be fixed on the wall surface by a fastening member.
The housing 100 has an air inlet 101 above, the air inlet 101 is provided with a plurality of air deflectors 150, and the air deflectors 150 can rotate relative to the middle frame 110, so as to adjust the air inlet angle or close the air inlet 101. Fig. 3 is a schematic diagram illustrating an opening of an air inlet 101 of an air conditioner 010 according to an embodiment of the present invention. As shown in fig. 3, the air guiding plate 150 of the present embodiment has six pieces, and is disposed at the air inlet 101 in an array. The air guiding plate 150 of this embodiment is a long plate, and the length thereof is approximately half of the length of the air inlet 101, and the width thereof is approximately one third of the width of the air inlet 101. Therefore, there are two rows of air deflectors 150 in the length direction of the intake vent 101 and three rows of air deflectors 150 in the width direction of the intake vent 101.
Fig. 4 is a schematic view illustrating a middle frame 110 and an air deflector 150 of an air conditioner 010 according to an embodiment of the present application; FIG. 5 is an enlarged view of portion V of FIG. 4; fig. 6 is an enlarged view of a portion VI in fig. 4. Referring to fig. 4 to 6, the driving members 160 of the present embodiment are three, the three driving members 160 are respectively located in the middle of the two air deflectors 150 in each row, and the driving members 160 are in transmission connection with the two air deflectors 150, so as to drive the two corresponding air deflectors 150 to rotate. The driving member 160 is fixed to the connecting member 112 of the middle frame 110, and the connecting member 112 extends from one long side of the air inlet 101 to the other long side, thereby dividing the air inlet 101 into two regions which are respectively opened or closed by two rows of air deflectors 150 (three air deflectors 150 in each row).
Because each air deflector 150 can adjust the inclination angle, the air inlet angle can be adjusted by rotating the air deflector 150 through the driving member 160, thereby changing the flow field from the air inlet 101 to the fan 200. Therefore, the rotatable air guide plate 150 provides a possibility of optimizing the operation state of the air conditioner 010 by adjusting the air intake angle. Each damper corresponds to an optimal inclination angle of the air guide plate 150, and if the air guide plate 150 is adjusted to the optimal inclination angle when the air conditioner is operated, the air conditioner 010 can be in an optimal operation state under the damper. The optimal operation state can comprehensively consider indexes such as noise, heat exchange efficiency, flow field, energy consumption of the fan 200 and the like. In this embodiment, the driving member 160 is a stepping motor, and the stepping motor can stably drive the air deflector 150 to rotate by a desired angle.
As shown in fig. 6, a first flange 152 and a second flange 154 are provided on both sides of the air deflector 150 in the width direction, the first flange 152 is close to the inner side surface of the air deflector 150, and the second flange 154 is close to the outer side surface of the air deflector 150, where the inner side surface is a surface facing the inside of the casing 100 when the air deflector 150 is closed, and the outer side surface is a surface facing the outside of the casing 100 when the air deflector 150 is closed. When the two air deflectors 150 adjacent to each other in the width direction of the air inlet 101 are closed, the first flange 152 of one air deflector 150 is matched with the second flange 154 of the other air deflector 150, so that the air deflectors 150 are more tightly closed, and dust and foreign matters are better prevented from entering the casing 100 from the air inlet 101.
The human-computer interaction device 300 is used for receiving instructions of a user, including starting up, shutting down, adjusting a windshield, adjusting a temperature, and the like. The human-computer interaction device 300 may be a device for receiving an infrared signal transmitted from a remote control panel, or may be a button, a keyboard, a touch screen, etc. on the air conditioner 010.
Fig. 7 is a block diagram illustrating the components of the air conditioner 010 according to an embodiment of the present invention. As shown in fig. 7, in the present embodiment, the controller 400 is electrically connected to the driving member 160, the blower 200, and the human-computer interaction device 300. The controller 400 may receive a user's instruction, control the start and stop of the fan 200, control the rotation speed of the driving member 160 to rotate a designated angle, and so on. In the embodiment of the present application, the controller 400 is configured to: determining the current gear of the fan 200; the driving member 160 is controlled to adjust the inclination angle of the air deflector 150 according to the current gear of the fan 200.
The controller 400 of the air conditioner 010 can control the driving member 160 to adjust the inclination angle of the air deflector 150 according to the current gear of the fan 200, so that the direction of the airflow entering the air conditioner 010 from the air inlet 101 can be adjusted as required. The air deflector 150 has a proper inclination angle, which can reduce the turbulence of the air flow, thereby reducing noise, and meanwhile, the smooth air flow is also beneficial to reducing the energy consumption of the fan 200. In addition, the air inlet angle of the air conditioner 010 is reasonable, so that the distribution of air flow on the heat exchange assembly is more uniform, and the heat exchange efficiency is improved. Therefore, the air conditioner 010 can adjust a proper air inlet angle according to the current gear of the fan 200, and the running state of the air conditioner 010 is favorably improved.
Specifically, each gear of the fan 200 corresponds to a preset inclination angle of the air deflector 150, and the controller 400 is specifically configured to: determining a preset inclination angle of the air deflector 150 corresponding to the current gear of the fan 200 as a target inclination angle of the air deflector 150 according to the corresponding relationship between each gear of the fan 200 and each preset inclination angle of the air deflector 150; calculating a rotation angle of the air deflector 150 according to the target inclination angle of the air deflector 150 and the current inclination angle of the air deflector 150; the driving member 160 is controlled to drive the air deflector 150 to rotate by a desired rotation angle.
The inclination angle of one air deflector 150 is preset for each gear of the fan 200, and when the air deflector 150 needs to be adjusted according to the windshield each time, the controller 400 can call the corresponding relationship to determine the preset inclination angle of the air deflector 150 corresponding to the current gear. Then, the controller 400 controls the driving member 160 to drive the air deflector 150 to rotate to the corresponding preset inclination angle according to the preset inclination angle corresponding to the current gear and the current inclination angle of the air deflector 150. The inclination angle corresponding to each gear of the fan 200 is preset, and the corresponding relationship between the gear and the inclination angle may be stored in a register integrated with the controller 400 or may be stored in a separately provided memory. The inclination angle is preset, and when the fan 200 operates at a certain gear, the controller 400 controls the driving member 160 to adjust the air deflector 150 to the preset inclination angle corresponding to the gear.
Further, the controller 400 is further configured to: according to the shutdown command received by the human-computer interaction device 300, the driving member 160 is controlled to drive the air deflector 150 to close the air inlet 101. The human-computer interaction device 300 can receive instructions of a user, including a shutdown instruction. The human-computer interaction device 300 sends the received shutdown instruction to the controller 400, and the controller 400 can control the driving member 160 to drive the air deflector 150 to close the air inlet 101.
Fig. 8 is a flowchart illustrating a method for controlling an air conditioner according to an embodiment of the present disclosure. The control method provided by the embodiment of the present application can be applied to the air conditioner 010 provided by the embodiment of the present application. As shown in fig. 8, the control method of the air conditioner includes:
and S100, determining the current gear of the fan.
Taking the air conditioner 010 provided in the embodiment of the present application as an example, the controller 400 determines the current gear of the fan 200, and may be implemented in the following manner:
1) determining the current gear of the fan 200 according to the rotating speed of the fan 200;
2) determining the current gear of the fan 200 according to an instruction input by a user, wherein the instruction input by the user comprises a target gear of the air conditioner 010;
3) and determining the current gear of the fan 200 according to the current wind speed of the air conditioner 010.
For the first and third modes, the gear can be accurately determined by actually measuring the current rotation speed of the fan 200 or the current wind speed. For the second mode, the step of actual measurement is saved, the interference possibly faced in the actual measurement process is not needed to be overcome, and the gear determining method is a stable gear determining mode.
And S200, controlling a driving piece to adjust the inclination angle of the air deflector according to the current gear of the fan.
Taking the air conditioner 010 provided in the embodiment of the present application as an example, the controller 400 controls the driving member 160 to adjust the inclination angle of the air deflector 150 according to the current gear of the fan 200. In an alternative embodiment, each gear of the fan 200 corresponds to a preset inclination of the air deflector 150, and optionally, the preset inclination is an optimal inclination of the air conditioner 010 in the gear, and is also an inclination that is most beneficial to the operation state of the air conditioner 010. Fig. 9 is a flowchart illustrating an embodiment of the present invention for controlling the driving member 160 to adjust the inclination angle of the air deflector 150. As shown in fig. 9, step S200 may specifically include:
step S210, determining a preset inclination angle of the air deflector corresponding to the current gear of the fan as a target inclination angle of the air deflector according to the corresponding relation between each gear of the fan and each preset inclination angle of the air deflector;
step S220, calculating a corresponding rotation angle of the air deflector according to the target inclination angle of the air deflector and the current inclination angle of the air deflector;
in step S230, the driving member is controlled to drive the air guiding plate to rotate by a corresponding rotation angle.
The inclination angle of the air deflector 150 is preset correspondingly for each gear of the fan 200, and when the air deflector 150 needs to be adjusted according to the windshield each time, the driving member 160 is controlled to drive the air deflector 150 to rotate according to the corresponding inclination angle and the current inclination angle of the air deflector 150, so that the feasible and efficient implementation method is provided. When the gear of the fan 200 is fixed, the air deflector 150 has a preferred inclination angle, so that the inclination angle is preset, and when the fan 200 operates at a certain gear, the air deflector 150 is directly adjusted to the preset inclination angle. The corresponding relationship between the shift position and the preset tilt angle may be stored in a register integrated with the controller 400, or may be stored in a separately provided memory (e.g., a hard disk, a removable hard disk, or a usb disk). The inclination angle is preset, and when the fan 200 operates at a certain gear, the controller 400 calls the corresponding relationship to determine the corresponding preset inclination angle, and then controls the driving member 160 to adjust the air deflector 150 to the preset inclination angle corresponding to the gear.
The preset inclination angles of the air deflectors 150 corresponding to the respective gears of the fan 200 may be determined according to the following manners:
testing the operation states of the air deflector 150 at different inclination angles of the fan 200 at each gear, wherein the operation states include at least one of heat exchange efficiency, noise and flow field; and determining a preset inclination angle of the air deflector 150 corresponding to each gear of the fan 200 according to the test result.
In each gear, a preferred inclination angle is selected as a preset inclination angle according to the performances of the air deflector 150 under different inclination angles by testing at least one of heat exchange efficiency, noise and a flow field. Then, in the actual operation process of the air conditioner 010, when the fan 200 operates at a certain gear, the inclination angle of the air deflector 150 is adjusted to the corresponding preset inclination angle, so that the air conditioner 010 can have a better operation state under different gears of the fan 200 in the actual operation process. Furthermore, the test method can be a simulation test through computer modeling, and can also be an actual test.
In an alternative embodiment, the control method of the air conditioner may further include: according to the shutdown command, the driving member 160 is controlled to drive the air deflector 150 to close the air inlet 101. After receiving the shutdown instruction, the air deflector 150 is controlled to close the air inlet 101, so that it can be ensured that no foreign matter, dust and the like enter the air inlet 101 when the air conditioner 010 is not in use, and the cleanliness of the interior of the air conditioner can be improved. The closing of the air deflector 150 may be specifically controlled by the following two methods:
1) when a shutdown instruction is received, controlling the driving member 160 to drive the air deflector 150 to close the air inlet 101;
2) after receiving the shutdown command, the driving member 160 is controlled to drive the air deflector 150 to close the air inlet 101 when the rotation speed of the fan 200 is zero.
By the two modes, the air deflector 150 can close the air inlet 101 when the air conditioner 010 is not in use. In the former method, a shutdown instruction is received as a trigger condition, and once the shutdown instruction is received, the rotation speed of the fan 200 is gradually reduced, and the air deflector 150 also performs a shutdown action synchronously. This makes synchronization efficient. The latter mode returns the rotation speed of the fan 200 to zero as a trigger condition, and closes the air inlet 101 when the rotation speed of the fan 200 returns to zero, which is beneficial to avoiding stronger negative pressure generated in the air conditioner 010.
In summary, according to the control method of the air conditioner provided by the embodiment of the application, the inclination angle of the air deflector can be adjusted according to the current gear of the fan, so that the direction of the airflow entering the air conditioner from the air inlet can be adjusted as required. The air deflector is positioned at a better inclination angle, the turbulence degree of the air flow can be reduced, and therefore noise is reduced, and meanwhile, smooth air flow is beneficial to reducing the energy consumption of the fan. In addition, the air inlet angle of the air conditioner is reasonably selected, so that the distribution of air flow on the heat exchange assembly is more uniform, and the heat exchange efficiency is improved. Therefore, in general, the proper air inlet angle is adjusted according to the current gear of the fan, and the running state of the air conditioner is favorably improved.
Embodiments of the present application also provide a computer-readable storage medium for storing an executable program, which when executed, can implement the control method of the air conditioner provided by the embodiments of the present application.
Although the present application is disclosed above, the present application is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present disclosure, and it is intended that the scope of the present disclosure be defined by the appended claims.
