Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a schematic flow chart of a method for controlling the rotation speed of an internal fan in an embodiment of the present invention, which can be applied to a segmented blowing air conditioner, and the method includes:
and S102, receiving a segmented air supply mode setting instruction input by a user after the air conditioner is started.
The user can input the setting instruction of the segmented air supply mode through a remote controller of the air conditioner or a control panel of the air conditioner. Usually, one or two inner fan rotating speed control keys are arranged on a remote controller or a control panel, and when a user presses or clicks once, a sectional air supply mode setting instruction is input into the air conditioner, and different sectional air supply modes are circularly switched according to a certain sequence. After the air conditioner is started, whether a user inputs a segmented air supply mode setting instruction or not is continuously detected.
And S104, controlling the air conditioner to blow air in the segmented air blowing mode.
The segmented air supply mode comprises a no-wind-sensation mode, the air deflector of the corresponding air outlet is closed in the no-wind-sensation mode, and a plurality of micropores are formed in the air deflector. When the air deflector is closed, the wind can be blown out from the micropores on the air deflector at a low speed, and the wind-sense-free air outlet is realized.
Alternatively, the segmented air supply mode of the air conditioner may include: the air supply mode comprises a full-open air supply mode in which the air deflectors of all air outlet sections are opened, a certain section of no-wind-sense mode corresponding to the closing of the air deflector of a certain air outlet section, a full-no-wind-sense mode in which the air deflectors of all air outlet sections are closed and the like.
And S106, determining a second rotating speed of the inner fan corresponding to the segmented air supply mode according to the air outlet area ratio and the first rotating speed of the inner fan.
The air outlet area ratio is the ratio of the air outlet area in the opening state in the segmented air supply mode to the air outlet area in the opening state in the fully-open air supply mode, and the first rotating speed of the inner fan is the rotating speed of the inner fan in the fully-open air supply mode.
Optionally, the area ratio of the air outlet corresponding to the segmented air supply mode may be executed according to the following steps:
firstly, the opening and closing state of the air deflector corresponding to the segmented air supply mode is obtained. Taking the sectional air supply air conditioner comprising the upper section air outlet, the middle section air outlet and the lower section air outlet as an example, if the sectional air supply mode is the upper non-wind sensing mode, the air deflector of the upper section air outlet is in a closed state, the air deflector of the middle section air outlet is in an open state, and the air deflector of the upper section air outlet is in an open state.
And then, dividing the area of the air outlet with the air deflector in the open state by the total area of the air outlet with the air deflector in the open state in the fully open air supply mode, and calculating to obtain the area ratio of the air outlet. Taking the above example, the area of the upper section of the air outlet is divided by the total area of the upper, middle and lower sections of the air outlet to obtain the area ratio of the air outlet.
Under different segmented air supply modes, the opening/closing states of air deflectors of air outlet sections of the air conditioner are different, so that the actual air output of the air outlet sections are different, and the air output noise difference is larger in the fully-opened air supply mode and the rotating speed control process of the inner fan due to the larger air output difference, noise fluctuation is generated, and user experience is poor. Based on this, this embodiment can combine the air outlet area ratio that segmentation air supply mode corresponds, carries out optimization adjustment to the internal fan rotational speed, reduces air-out noise fluctuation. The larger the area ratio of the air outlets is, the more the air outlets opened by the air deflector are, and the difference between the noise of the air deflector and the noise of the fully-opened air supply mode is smaller under the condition; the smaller the area ratio of the air outlets is, the fewer the air outlets opened by the air deflector are, and the difference between the noise of the air deflector and the noise of the fully-opened air supply mode is larger under the condition; therefore, the relation between the second rotating speed of the inner fan and the area ratio of the air outlet is set to be negative correlation.
And S108, controlling the inner fan of the air conditioner to operate at a second rotating speed of the inner fan.
The method for controlling the rotating speed of the inner fan provided by the embodiment is characterized in that when a user sets a segmented air supply mode, on one hand, the air conditioner is controlled to supply air in the set segmented air supply mode, on the other hand, the inner fan is controlled to operate in a second rotating speed, the second rotating speed is determined by the ratio of the set segmented air supply mode to the area of the air outlet in the opening state of the fully-opened air supply mode, the rotating speed of the inner fan in different segmented air supply modes is adjusted through the ratio corresponding to different segmented air supply modes, the air outlet uniformity is improved, the noise values of the different segmented air supply modes are kept at similar levels, and the use experience of.

F＝F1+F1*(1-X％)
wherein F is the second rotating speed of the inner fan, F1The first rotating speed of the inner fan is adopted, and X is the area ratio of the air outlet.
Considering that the air outlet noise is related to the current rotating speed of the inner fan besides the opening and closing state of the air deflector, the air volume correction coefficient related to the current rotating speed can be added in the calculation process of the current rotating speed of the inner fan so as to optimize the effect of noise maintenance. Alternatively, the step S106 may be executed as follows:
first, an air volume correction coefficient is acquired. The air volume correction coefficient is used for reducing the air volume attenuation of the segmented air supply mode and is an empirical value calculated according to an experimental result. In the actual configuration process, the specific value of the air volume correction coefficient can be set by combining the rotating speed characteristics of an internal fan of the air conditioner, the shape, the position and the area of an air outlet, the strength of each factor generating noise and the like.
And then, determining a second rotating speed of the inner fan corresponding to the segmented air supply mode according to the air outlet area ratio, the first rotating speed of the inner fan and the air volume correction coefficient.
Optionally, the calculation formula of the second rotation speed of the inner fan is as follows:
F＝F1+F1*(1-X％)*Y％
wherein F is the second rotating speed of the inner fan, F1The first rotating speed of the inner fan is adopted, X is the air outlet area ratio, and Y is the air quantity correction coefficient. Optionally, the value range of the air volume correction coefficient is 5% to 20%.
