Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control method of an air conditioner, a control device of an air conditioner, and an air conditioner having the control device according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of an air conditioner according to an embodiment of the present invention.
In an embodiment of the present invention, the air conditioner may include at least two fans located at different heights and an air guiding mechanism such as an air guiding grille disposed corresponding to the fans, for example, in combination with fig. 2 and 3, the air conditioner is a multi-port vertical air conditioner, the fans and the fan blades are disposed on the left, right, middle, and lower portions between the heat exchanging assembly and the front panel, and the fan blades are driven by the fans to blow out heat or cold generated by the heat exchanger through the air guiding mechanism. The air guide mechanism has a set inclination angle, for example, a certain inclination angle of 0 to 90 degrees, and the air guide mechanism can rotate along the axial direction of the fan, that is, the air guide mechanism can rotate 360 degrees, as shown in fig. 4, the arrow direction is the direction of the inclination angle of the air guide mechanism.
As shown in fig. 1, the method for controlling an air conditioner according to an embodiment of the present invention includes:
and S1, receiving a far and near no-wind feeling mode starting instruction.
And S2, controlling the air guide mechanism to rotate to a preset non-wind-sensing angle according to the far and near non-wind-sensing mode starting instruction, and adjusting the frequency of the compressor and/or the rotating speed of the fan according to the distance between a person and the air conditioner.
It should be noted that the near-far no-wind-sense mode is a form of no-wind-sense refrigeration, the distance is automatically detected by infrared or manually selected, and the no-wind-sense refrigeration effect can be realized within the distance by adjusting the rotating speed of each fan and the frequency of the compressor.
Specifically, when a user needs to use the air conditioner to start the near-far no-wind mode, the user sends a starting instruction remotely through a remote controller such as an infrared remote controller, or sends the starting instruction through a starting button on a control panel of the air conditioner to control the air conditioner to start. And then, a remote refrigeration mode starting instruction is sent through a remote controller, or a refrigeration instruction is sent through a refrigeration mode key on a control panel of the air conditioner (of course, if the air conditioner runs in a refrigeration mode before the air conditioner is started, the air conditioner still keeps in the refrigeration mode after the air conditioner is started, the step can be omitted), so that the air conditioner is controlled to run in the refrigeration mode. And then, a far and near no-wind feeling mode instruction is sent remotely through a remote controller, or a far and near no-wind feeling mode starting instruction is sent through a no-wind feeling mode key on a control panel of the air conditioner (of course, if the air conditioner runs the far and near no-wind feeling mode before the air conditioner is started, the far and near no-wind feeling mode is still kept after the air conditioner is started, the step can be omitted, namely the air conditioner automatically starts the far and near no-wind feeling mode). After that, the distance instruction between the person and the air conditioner is sent remotely through a remote controller, or the distance instruction between the person and the air conditioner is sent through a distance key on a control panel of the air conditioner (of course, if a detection module capable of detecting the distance between the person and the air conditioner, such as an infrared detection module, is arranged on the air conditioner, this step may be omitted, and the air conditioner may detect the distance between the person and the air conditioner in real time through the detection module).
After the air conditioner receives the opening instruction of the far and near non-wind-sensing mode, the rotation angle of the air guide mechanism is adjusted to a preset non-wind-sensing angle, so that cold wind blows to the periphery, and the infrared detection is inquired once every preset time (such as 60s) or the distance between the person and the air conditioner is manually selected, the corresponding frequency of the compressor and the rotating speed of the fan are obtained according to the preset relation between the distance between the person and the air conditioner, for example, the frequency of the compressor and the rotating speed of the fan are obtained through a table look-up mode (the relation between the distance between a person and the air conditioner and the frequency of the compressor and the rotating speed of the fan are obtained in advance and stored in the air conditioner) or a calculation mode (the relation between the distance between the person and the air conditioner and the frequency of the compressor and the rotating speed of the fan are established in advance through big data and stored in the air conditioner), and adjusting the compressor and the fan according to the obtained frequency of the compressor and the obtained rotating speed of the fan. Therefore, according to the distance between a person and the air conditioner, the method can achieve no wind feeling in different areas, meet the no-wind feeling requirements of different users, and improve the thermal comfort experience of the different users.
Taking the air conditioner shown in fig. 2 as an example, first, how to adjust the angle of the air guiding mechanism when the air conditioner receives the opening command of the far and near non-wind-sensing mode will be described.
According to an embodiment of the present invention, the controlling the wind guiding mechanism to rotate to a preset non-wind angle includes: the air guide mechanism positioned at the upper part is controlled to rotate to a preset first angle, the air guide mechanism positioned at the middle lower part is controlled to rotate to a preset second angle, and the position corresponding to the first angle is closer to the position corresponding to 0 degree than the position corresponding to the second angle. The first angle and the second angle can be set according to actual needs, for example, the first angle can be 300-360 degrees or 0-60 degrees, and the second angle can be 270-330 degrees or 30-90 degrees.
Specifically, when the near-far non-wind-sensing mode is started, the air guide mechanism positioned on the left of the upper part is adjusted to rotate clockwise by 300 degrees to 360 degrees (of course, the air guide mechanism positioned on the right of the upper part can also rotate anticlockwise by 0 degrees to 60 degrees), the air guide mechanism positioned on the left of the middle-lower part is adjusted to rotate clockwise by 270 degrees to 330 degrees (of course, the air guide mechanism positioned on the right of the middle-lower part can also rotate anticlockwise by 300 degrees to 360 degrees), the air guide mechanism positioned on the left of the middle-lower part is adjusted to rotate clockwise by 30 degrees to 90 degrees (of course, the air guide mechanism positioned on the right of the middle-lower part can also rotate anticlockwise by 270 degrees to 330 degrees), and cold air can be blown to the periphery.
Continuing with the air conditioner shown in fig. 2 as an example, how the air conditioner specifically adjusts the frequency of the compressor when receiving the on command of the near-far no-wind mode will be described.
According to one embodiment of the present invention, the frequency of the compressor is positively correlated with the distance between the person and the air conditioner. That is, the farther a person is from the air conditioner, the greater the frequency of the compressor; the closer a person is to the air conditioner, the less the frequency of the compressor.
According to an embodiment of the present invention, adjusting the frequency of the compressor according to the distance between a person and the air conditioner includes: determining a distance range interval corresponding to the distance between a person and the air conditioner; and adjusting the frequency of the compressor according to the distance range interval.
According to an embodiment of the present invention, adjusting the frequency of the compressor according to the distance range section includes: if the distance between the person and the air conditioner exceeds a preset first distance threshold value and does not exceed a preset second distance threshold value, adjusting the frequency of the compressor to be a preset first frequency; and if the distance between the person and the air conditioner does not exceed the first distance threshold, adjusting the frequency of the compressor to be a preset second frequency, wherein the second frequency is lower than the first frequency.
The preset first distance threshold and the preset second distance threshold may be set according to the power of the air conditioner, for example, the preset first distance threshold may be 6m, the preset second distance threshold may be 10m, and the preset first frequency FWindless MAXThe frequency of the second frequency is set according to the performance of the compressor, for example, the frequency can be 20 to 60Hz, preferably 44Hz, and the preset second frequency is S1*(FWindless MAX-FWindless Min) Preset first distance threshold + FWindless Min，S1Rounding the distance between person and air conditioner, FWindless MinThe minimum frequency value of the compressor in the non-wind sensing mode can be 10-40 Hz, and is preferably 20 Hz.
Specifically, the range of the distance S between a person and the air conditioner is selected to be 0-10 m through infrared detection or manual selection, and S is required to be rounded to be an integer S at the moment because S may not be integral1. When obtaining S1Then, judge S1A magnitude relation with a preset first distance threshold (e.g. 6m) and a preset second distance threshold (e.g. 10m), wherein when S is1When the frequency is less than or equal to 6m, adjusting the frequency Fr of the compressor to be S1*(FWindless MAX-FWindless Min)/6+FWindless Min(ii) a When 6m < S1 < 10m, the frequency Fr of the compressor is adjusted to FWindless MAX。
Continuing with the air conditioner shown in fig. 2 as an example, how to adjust the rotation speed of the fan when the air conditioner receives the far-near no-wind-sensation mode starting command will be described in detail.
According to one embodiment of the invention, for the fans at the same height, the rotating speed of the fan is in positive correlation with the distance between a person and the air conditioner; the rotating speed of the fan and the position height of the fan are in positive correlation at the same moment. That is to say, two fan rotational speeds on upper portion equal, and two fan rotational speeds at the middle part equal, and two fan rotational speeds of lower part equal, and the fan rotational speed of upper portion is greater than the fan rotational speed at the middle part, and the fan rotational speed at the middle part is greater than the fan rotational speed of lower part.
