According to the scheme, the indoor unit of the air conditioner is provided with a plurality of air outlets, and each air outlet is provided with a corresponding counter-rotating fan which comprises two wind wheels in counter-rotating arrangement; the air conditioner acquires a user of a space where the air conditioner is located, so that the target rotating speed of each wind wheel in each counter-rotating fan is determined according to the user, and each wind wheel is controlled to operate according to the target rotating speed, so that the air supply distance of each counter-rotating fan is smaller than the user distance between the position of the user and the air conditioner, and the air conditioner can supply air without wind sense to the user; because the air conditioner realizes no wind sensation by controlling the rotating speed of the wind wheels corresponding to the plurality of air outlets, the air conditioner ensures the output of cold energy while reducing the air quantity conveyed to users, and also ensures the refrigeration effect of the air conditioner.
Based on the hardware architecture, the embodiment of the control method of the air conditioner is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a control method of an air conditioner according to the present invention, the control method of the air conditioner including the steps of:
step S10, determining the user of the space where the air conditioner is located;
in the present invention, referring to fig. 3, a plurality of air outlets are provided on an indoor unit of an air conditioner, and a corresponding counter-rotating fan is provided for each air outlet, and the counter-rotating fan can be provided at the air outlet, that is, in an air outlet channel connected to the air outlet. The air conditioner is provided with an image acquisition device which can be a camera. The air conditioner can determine the user of the space where the air conditioner is located through the image acquisition device.
Step S20, determining the target rotating speeds of two wind wheels in each counter-rotating fan according to the user;
the air conditioner may determine a target rotation speed of each wind wheel in each counter-rotating fan according to the determined user. The user can be viewed as user information, and the user information includes the number of users and the distance between the user and the air conditioner, i.e., the user distance.
Specifically, the air conditioner firstly determines the number of users;
when the number of users is less than the number of the counter-rotating fans, at this time, the air conditioner may configure a corresponding counter-rotating fan for each user to supply air to the user without wind sensation, the air conditioner may set the air outlets to be arranged up and down, and the farther (larger) the user is from the air conditioner, the larger the height of the air outlet corresponding to the counter-rotating fan configured for the user with respect to the ground is, and the distance of the air outlet corresponding to the counter-rotating fan with respect to the ground may be proportional to the user distance of the user corresponding to the counter-rotating fan, for example, the air conditioner is provided with three air outlets, the position of the first air outlet is higher than the position of the second air outlet (the height with respect to the ground, the first air outlet is higher than the second air outlet), the position of the second air outlet is higher than the position of the third air outlet, and the current space has two users, one user is 3, the position of the air outlet configured for the user with the distance of 3m is lower than that of the air outlet configured for the user with the distance of 4m, that is, the air conditioner can configure a corresponding counter-rotating fan according to the user distance between each user and the air conditioner;
after configuring corresponding counter-rotating fans for each user, taking each counter-rotating fan as a target counter-rotating fan corresponding to the user;
the air conditioner determines the air supply distance (first air supply distance) of a target counter-rotating fan corresponding to the user according to the user distance, and determines the target rotating speed of each wind wheel in the target counter-rotating fan according to the first air supply distance so that the air supply distance of the target counter-rotating fan is smaller than the user distance of the user corresponding to the target counter-rotating fan, and therefore the target counter-rotating fan can supply air to the user corresponding to the target counter-rotating fan without wind sensation;
because the number of users is less than that of the counter-rotating fans, other counter-rotating fans are remained after the target counter-rotating fans are removed; in order to ensure effective output of cold quantity in the indoor unit and avoid frosting of the evaporator caused by excessive cold quantity of the indoor unit, the air conditioner can control each wind wheel in other counter-rotating fans to operate at the lowest rotating speed, namely the lowest rotating speed of each wind wheel in other counter-rotating fans is the target rotating speed corresponding to each wind wheel in other counter-rotating fans, namely the lowest rotating speed corresponding to each wind wheel in each counter-rotating fan is arranged in the air conditioner.
In addition, when the number of the users is larger than or equal to that of the counter-rotating fans, all the counter-rotating fans need to supply air to the users without wind sense, at the moment, all the counter-rotating fans serve as target counter-rotating fans, namely, one target counter-rotating fan corresponds to at least one user, the air conditioner can select users close to each other to share one target counter-rotating fan (the distance between the two users is smaller than the preset distance, the two users can be judged to be close to each other), and therefore each user has the corresponding target counter-rotating fan;
the rule of the target counter-rotating fan configured for the user can also be configured according to the user distance, namely the larger the user distance is, the higher the position of the air outlet corresponding to the target counter-rotating fan corresponding to the user is in the air conditioner;
the target rotating speed of each wind wheel in the target counter-rotating fan can be determined according to the user distance corresponding to the target counter-rotating fan, and the determining process is not repeated one by one.
Step S30, controlling each wind wheel to operate according to a corresponding target rotating speed so that the air supply distance of each counter-rotating fan is smaller than the distance of a user, wherein the distance of the user is the distance between the position where the user is located and the air conditioner;
after the air conditioner determines the rotating speed of each wind wheel in each counter-rotating fan, each wind wheel can be controlled to operate according to the determined target rotating speed; in addition, each air outlet of the air conditioner is also provided with an air guide strip, and after the air conditioner configures corresponding counter-rotating fans for each user, the air conditioner determines the air supply direction of the counter-rotating fans according to the direction of the counter-rotating fans corresponding to the user and the user; therefore, when each wind wheel runs according to the determined target rotating speed, the angle of the wind guide strip of the air outlet where each counter-rotating fan is located is adjusted according to the air supply direction, and therefore the air conditioner can supply air to each user without wind sense. Certainly, after the air conditioner determines the user in the space, the air supply direction of each counter-rotating fan can be determined, and after each wind wheel runs according to the corresponding target rotating speed, the angle of the air guide strip of the air outlet where each counter-rotating fan is located can be adjusted according to the air supply direction, so that the air outlet supplies air to the corresponding user.
It should be noted that the image acquisition device may be an infrared camera, and the air conditioner may acquire the average body temperature of the user and the ambient temperature around the user through the infrared camera; the air conditioner can determine the air supply temperature of the air conditioner according to the average body temperature of a user and the ambient temperature, the air supply temperature is lower when the difference value between the average body temperature and the ambient temperature is larger (the average body temperature is higher than the ambient temperature), and the air conditioner adjusts the frequency of an air conditioner compressor and the opening degree of an electronic expansion valve according to the air supply temperature.
