Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
When the outdoor unit of the air conditioner is located at the roadside or other public areas, the wind from the fan of the outdoor unit may blow directly on passers-by. In the embodiment of the disclosure, the air conditioner can control the rotating speed of the fan of the outdoor unit of the air conditioner according to the human body number information in the set range of the outdoor unit, that is, when the human body number information meets the set condition, the rotating speed of the fan of the outdoor unit of the air conditioner is reduced, so that the air volume directly blown to passerby is reduced, the body feeling of a user is improved, thereby the intelligence of the air conditioner is enhanced, and the limitation on the use or installation environment of the air conditioner is reduced.
Fig. 1 is a flowchart illustrating a method for controlling a fan of an outdoor unit of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the process of controlling the fan of the outdoor unit of the air conditioner includes:
step 101: and acquiring the current human body number information within the set range of the air conditioner outdoor unit.
The air conditioner outdoor unit may be provided with a human body detection device, for example: infrared sensors, ultrasonic sensors, etc. Generally, the setting range of the air conditioner outdoor unit can be determined according to the action range of the human body detection device and the position on the air conditioner outdoor unit. Namely, the signal and the installation position of the human body detection device are determined, and the corresponding set range can be obtained. Therefore, the human body number information in the set range of the air conditioner outdoor unit can be acquired through the human body detection device. Wherein, the human body number information may include: the number of human bodies. Of course, it may also include: body size information, etc.
Of course, the setting range of the outdoor unit of the air conditioner may be divided into two, three or more areas. Generally, the division can be made according to the distance, for example: the air conditioner is divided into two areas, namely a first setting range and a second setting range, wherein a first distance from a first center position of the first setting range to the air conditioner outdoor unit is greater than a second distance from a second center position of the second setting range to the air conditioner outdoor unit. Or, the air conditioner is divided into a plurality of areas, a first setting range, a second setting range and a third setting range, wherein a first distance from a first center position of the first setting range to the air conditioner outdoor unit is the largest, and a third distance from a third center position of the third setting range to the air conditioner outdoor unit is the smallest.
The information of the number of the human bodies in the set range of the air conditioner outdoor unit can be acquired regularly, and the acquired information of the number of the human bodies each time is the corresponding information of the number of the current human bodies.
Step 102: and when the current human body number information meets the set conditions, reducing the initial rotating speed of the fan of the air conditioner outdoor unit which is stored.
When the air conditioner normally operates, the rotating speed of the fan of the outdoor unit can be adjusted according to the operating state of the air conditioner, so that the rotating speed of the fan corresponding to the current operating state of the air conditioner can be determined as the initial rotating speed and stored.
Generally, when there is a person in the setting range of the outdoor unit, the rotation speed of the fan of the outdoor unit needs to be reduced, so that the amount of air directly blown to passers-by is reduced, therefore, when the rotation speed of the fan is controlled, the fan can be adjusted to a lower rotation speed when there is a person in the setting range of the outdoor unit, and when there is no person in the setting range of the outdoor unit, the fan can be restored to the initial rotation speed, namely, a lower fixed rotation speed when there is a person, and another higher fixed rotation speed when there is no person. Or, as long as the human body detection device detects that a person is present at a time, the rotating speed of the fan is reduced at a time, that is, the rotating speed of the fan can be continuously reduced; of course, in order to maintain the normal function of the air conditioner, a minimum rotation speed may be previously set such that the lowering is stopped when the rotation speed of the fan is lowered by a value that sets the minimum rotation speed.
Alternatively, since the setting range may be divided into two or more regions, the fan may be controlled according to different information on the number of human bodies in each region.
Therefore, in the embodiment of the present disclosure, reducing the saved initial rotation speed of the fan of the outdoor unit of the air conditioner includes: when the number of human bodies in the current human body number information is not zero, acquiring the current rotating speed of a fan of the air conditioner outdoor unit, and subtracting a set value from the current rotating speed to obtain a first rotating speed; when the first rotating speed is greater than or equal to the set lowest rotating speed, adjusting the rotating speed of the fan to the first rotating speed; and when the first rotating speed is less than the set lowest rotating speed, adjusting the rotating speed of the fan to the set lowest rotating speed.
Or, the reducing the stored initial rotation speed of the fan of the outdoor unit of the air conditioner includes: when the number of the human bodies in the current human body number information is not zero and the number of the human bodies in the previous human body number information is zero, subtracting a set value from the initial rotating speed to obtain a reduced rotating speed, and adjusting the rotating speed of the fan to the reduced rotating speed.
Or, the reducing the stored initial rotation speed of the fan of the outdoor unit of the air conditioner includes: when the first human body number in the first current human body number information corresponding to the first set range is not zero and the second human body number in the second current human body number information corresponding to the second set range is zero, adjusting the rotating speed of the fan to a first set rotating speed, wherein the first set rotating speed is less than the initial rotating speed, and the first distance from the first center position of the first set range to the air-conditioning outdoor unit is greater than the second distance from the second center position of the second set range to the air-conditioning outdoor unit; and when the number of the second human bodies is not zero, adjusting the rotating speed of the fan to a second set rotating speed, wherein the second set rotating speed is less than the first set rotating speed.
Therefore, in the embodiment, the rotating speed of the fan of the outdoor unit of the air conditioner can be controlled according to the human body number information in the set range of the outdoor unit, namely, when the human body number information meets the set condition, the rotating speed of the fan of the outdoor unit of the air conditioner is reduced, so that the air volume of the human body around the outdoor unit of the air conditioner is reduced, the body feeling of a user is improved, the intelligence of the air conditioner is enhanced, and the limitation on the use or installation environment of the air conditioner is reduced.
Of course, if no person is in the set range of the outdoor unit of the air conditioner, the initial rotating speed of the fan can be recovered, so that the normal function operation of the air conditioner can be ensured. Therefore, the rotating speed of the fan can be recovered to the initial rotating speed when no person is in the set range of the air conditioner outdoor unit. Accordingly, the fan control process may further include: and when the number of the human bodies in the current human body number information is zero, adjusting the rotating speed of the fan to the initial rotating speed.
In order to ensure the normal function operation of the air conditioner and avoid the long-time low-speed operation of the outdoor unit fan, a set time length can be configured in advance, so that when the time that the number of human bodies in the current human body number information is not zero exceeds the set time length, the rotating speed of the fan is adjusted to the initial rotating speed, and voice prompt information is sent out. The accessible drive voice alarm module sends voice prompt information, and the suggestion passerby leaves the settlement region as soon as possible, reduces the probability that the bad body of user is felt, further improves the intellectuality of air conditioner.
Similarly, since the setting range is divided into two or more regions, the fan control may further include: when the number of the second human bodies is zero and the time when the number of the first human bodies is not zero exceeds a set length, adjusting the rotating speed of the fan to the initial rotating speed; and when the time that the number of the second human bodies is not zero exceeds the set time length, adjusting the rotating speed of the fan to the initial rotating speed, and sending out voice prompt information.
Therefore, as long as a person is in the second setting range which is relatively close to the outdoor unit of the air conditioner and the time is longer than the set time, whether the person is in the first setting range or not, the rotating speed of the fan needs to be adjusted to the initial rotating speed, and voice information is sent out to prompt passers-by to leave as soon as possible. And when the set time is over, the rotating speed of the fan is only required to be adjusted to the initial rotating speed, so that the normal operation of the air conditioner is guaranteed.
The following operational flows are integrated into the specific embodiments to illustrate the control method provided by the embodiments of the present invention.
In an embodiment of the present disclosure, the human body detecting device may be an infrared sensor, and is located at a front side of the outdoor unit of the air conditioner.
Fig. 2 is a flowchart illustrating a method for controlling a fan of an outdoor unit of an air conditioner according to an embodiment of the disclosure. As shown in fig. 2, the process of controlling the fan of the outdoor unit of the air conditioner includes:
step 201: is the timing detection time reached? If yes, go to step 202, otherwise, go back to step 201.
Step 202: and acquiring the number of the current human bodies in the set range of the outdoor unit of the air conditioner through the infrared sensor.
Step 203: is the current number of human bodies not zero? If so, go to step 204, otherwise, go to step 207.
Step 204: is the previous number of human bodies judged to be zero? If yes, go to step 205, otherwise, go back to step 201.
Step 205: and acquiring the current rotating speed of a fan of the air conditioner outdoor unit, storing the number of the current human bodies, and storing the current rotating speed as the initial rotating speed.
Step 206: and subtracting a set value from the initial rotating speed to obtain a reduced rotating speed, and adjusting the rotating speed of the fan to the reduced rotating speed. Returning to step 201.
Step 207: and adjusting the current rotating speed of a fan of the air conditioner outdoor unit to the initial rotating speed. Returning to step 201.
Therefore, in the embodiment, the rotating speed of the fan of the outdoor unit of the air conditioner can be reduced when the number of the human bodies is zero for the first time, so that the air volume of the human bodies around the outdoor unit of the air conditioner is reduced, the body feeling of a user is improved, the intelligence of the air conditioner is enhanced, and the limitation to the use or installation environment of the air conditioner is reduced.
In another embodiment of the present disclosure, the human body detecting device may be an ultrasonic sensor, and is located at a front side of the outdoor unit of the air conditioner.
Fig. 3 is a flowchart illustrating a method for controlling a fan of an outdoor unit of an air conditioner according to an embodiment of the disclosure. As shown in fig. 3, the process of controlling the fan of the outdoor unit of the air conditioner includes:
step 301: is the timing detection time reached? If yes, go to step 302, otherwise, go back to step 301.
Step 302: and acquiring the number of the current human bodies in the set range of the air conditioner outdoor unit through the ultrasonic sensor.
Step 303: is the current number of human bodies not zero? If so, go to step 304, otherwise, go to step 310.
Step 304: is the current time when the number of human bodies is not zero exceed a set time length? If so, go to step 309, otherwise go to step 305.
Step 305: and subtracting a set value from the current rotating speed of the fan of the air conditioner outdoor unit to obtain a first rotating speed.
Step 306: is it determined whether the first rotational speed is greater than or equal to the set minimum rotational speed? If yes, go to step 307, otherwise go to step 308.
The maximum rotation speed is less than the initial rotation speed, and for the first time, the current rotation speed is the initial rotation speed and is greater than the maximum rotation speed, step 307 may be executed.
Step 307: the rotation speed of the fan is adjusted to the first rotation speed, and the step 301 is returned to.
Step 308: the rotation speed of the fan is adjusted to the set lowest rotation speed, and the process returns to step 301.
Step 309: and adjusting the rotating speed of the fan to the stored initial rotating speed, and sending out voice prompt information. Returning to step 301.
Here, voice prompt information can be sent out by driving the voice alarm module, so that passing passers-by are prompted to leave a set area as soon as possible, and the probability of bad body feeling of a user is reduced.
Step 310: and adjusting the rotating speed of the fan to the stored initial rotating speed. Returning to step 301.
Similarly, the initial rotating speed of the fan can be recovered when no person is in the set range of the air conditioner outdoor unit.
Therefore, in the embodiment of the disclosure, when a person is in the setting range of the air conditioner outdoor unit, the rotating speed of the fan of the air conditioner outdoor unit is reduced until the lowest rotating speed is set, and the normal function of the air conditioner is ensured, and meanwhile, the rotating speed of the fan of the air conditioner outdoor unit is reduced to the maximum extent, so that the air volume of a human body around the direct-blowing air conditioner outdoor unit is reduced, the body feeling of a user is improved, the intelligence of the air conditioner is enhanced, and the limitation on the use or installation environment of the air conditioner is reduced. And, the air conditioner outdoor unit can resume the initial rotating speed of the fan when nobody is in the set range or nobody is in the set range for a long time, thereby ensuring the normal function operation of the air conditioner. And voice information prompt can be carried out, so that the intelligence of the air conditioner is further improved.
In an embodiment of the present disclosure, the human body detecting device may be an infrared sensor, and is located at a front side of the outdoor unit of the air conditioner. The area in front of the outdoor unit of the air conditioner may be divided into two or three areas.
Fig. 4 is a schematic diagram illustrating division of a setting area of an outdoor unit of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 4, there are three areas a, B, and C in front of the outdoor unit, wherein a and C are symmetrical with respect to an outdoor unit axis, and thus a and C can be determined as a first setting range and B can be determined as a second setting range.
Fig. 5 is a flowchart illustrating a method for controlling a fan of an outdoor unit of an air conditioner according to an embodiment of the disclosure. As shown in fig. 5, the process of controlling the fan of the outdoor unit of the air conditioner includes:
step 501: is the timing detection time reached? If yes, go to step 502, otherwise, go back to step 501.
Step 502: and acquiring a first current human body number corresponding to a first set range of the outdoor unit of the air conditioner and a second current human body number corresponding to a second set range through the infrared sensor.
And judgment 503: is it determined whether the second current number of human bodies is not zero? If so, go to step 504, otherwise, go to step 506.
Step 504: determine whether the time that the second current number of human bodies is not zero exceeds the set time? If so, go to step 510, otherwise, go to step 505.
Step 505: and adjusting the rotating speed of the fan to a second set rotating speed. Returning to step 501.
In this example, the second set rotational speed is less than the first set rotational speed, and the first set rotational speed is less than the start rotational speed. For example: a second setpoint value can be preset, so that the second setpoint rotational speed is equal to the starting rotational speed — the second setpoint value.
Step 506: is the first current number of human bodies determined not to be zero? If yes, go to step 507, otherwise go to step 509.
Step 507: determine whether the time that the first current number of human bodies is not zero exceeds the set duration? If so, go to step 509, otherwise, go to step 508.
Step 508: the rotation speed of the fan is adjusted to a first set rotation speed. Go back to step 501.
The first set rotational speed is less than the initial rotational speed. For example, a first setpoint value can be preset, so that the first setpoint rotational speed is equal to the starting rotational speed — the first setpoint value, wherein the second setpoint value is greater than the first setpoint value.
Step 509: the rotation speed of the fan is adjusted to the initial rotation speed. Returning to step 501.
Step 510: and adjusting the rotating speed of the fan to the initial rotating speed, and sending voice prompt information. Returning to step 501.
Therefore, in the embodiment of the disclosure, when people exist in different setting ranges of the air conditioner outdoor unit, the rotating speed of the fan of the air conditioner outdoor unit can be reduced to different degrees, and the reduction range of the area close to a point is larger, so that the normal function of the air conditioner is guaranteed, the air volume of a human body around the direct-blowing air conditioner outdoor unit is reduced to the greatest extent, the body feeling of a user is improved, the intelligence of the air conditioner is enhanced, and the limitation on the use or installation environment of the air conditioner is reduced. And, the air conditioner outdoor unit can resume the initial rotating speed of the fan when nobody is in the set range or nobody is in the set range for a long time, thereby ensuring the normal function operation of the air conditioner. And voice information prompt can be carried out, so that the intelligence of the air conditioner is further improved.
According to the process of controlling the fan of the air-conditioning outdoor unit, a device for controlling the fan of the air-conditioning outdoor unit can be constructed.
Fig. 6 is a schematic structural diagram of an air conditioner outdoor unit fan control device according to an embodiment of the present disclosure. As shown in fig. 6, the fan control device of the outdoor unit of the air conditioner includes: an acquisition unit 100 and a first control unit 200.

Thus, if the current number of human bodies is not zero but the time of non-zero exceeds the preset time, the third control unit 400 can adjust the rotation speed of the fan to the initial rotation speed and send out voice prompt information. When the number of the current human bodies is zero, the second control unit 300 may directly adjust the rotation speed of the fan to the initial rotation speed.
Therefore, in the embodiment, the fan control device of the air conditioner outdoor unit can reduce the rotating speed of the fan of the air conditioner outdoor unit until the lowest rotating speed is set when a person is in the set range of the air conditioner outdoor unit, and reduce the rotating speed of the fan of the air conditioner outdoor unit to the maximum extent while ensuring the normal function of the air conditioner, so that the air volume of a human body around the direct-blowing air conditioner outdoor unit is reduced, the body feeling of a user is improved, the intelligence of the air conditioner is enhanced, and the limitation on the use or installation environment of the air conditioner is reduced. And, the air conditioner outdoor unit can restore the rotating speed of the fan when nobody is in the set range or nobody is in the set range for a long time, thereby ensuring the normal function operation of the air conditioner.
