For example, the user can carry out air-out mode setting through APP, remote controller or display screen etc. and the air-out mode is for example including last air-out mode or air-out mode etc. down. Alternatively, the factory default state may be the upward air-out mode.
Different from the air conditioner with only a lower air duct in the related art, the air conditioner provided by the embodiment of the application is a double-air-duct air conditioner, and not only has the lower air duct, but also comprises an upper air duct.
Fig. 2 is a schematic structural diagram of a dual-duct air conditioner according to an embodiment of the present application. As shown in fig. 2, the air conditioner provided in the embodiment of the present application includes an upper air deflector 1, an upper air duct 2, a casing 3, a middle baffle 4, a lower air deflector 5, a lower air duct 6, an evaporator 7, a cross flow fan 8, and an upper air inlet 9. Fig. 2 is a side perspective view of a wall-mounted air conditioner (i.e., showing the structure of the inside of the air conditioner) after the wall-mounted air conditioner is normally installed, taking the wall-mounted air conditioner as an example. It should be understood that in the embodiments of the present application, if not specifically stated, "upper" and "lower" refer to the upper and lower relationship of the air conditioner during normal use after being normally installed, for example, referring to fig. 2, the upper air guiding plate 1 is located above the lower air channel plate 5, and the opposite lower air channel plate 5 is located below the upper air channel plate 1. Similarly, the upper duct 2 is located above the lower duct 6, and the lower duct 6 is located below the upper duct 2.
S12: controlling the lower air duct to perform state switching, wherein the state switching comprises the following steps: switching from a closed state to an open state and/or switching from an open state to a closed state.
When the air outlet mode is determined to be the upper air outlet mode, the upper air duct is kept in an open state, and the lower air duct is switched in state in the whole operation process of the upper air outlet mode. The interval opening of the lower air duct can be realized through continuous state switching, wherein the interval opening means that the lower air duct is closed firstly, opened after a period of time and closed after a period of time, and the like, and the lower air duct is continuously circulated between closing, opening, closing and opening. That is, when the upper air outlet mode is opened, only upper air outlet is performed (the upper air duct is controlled to be opened, and the lower air duct is controlled to be closed), and the lower air duct is opened after the upper air outlet is operated for a certain time (the time can be represented by a first time length), that is, both the upper air duct and the lower air duct are opened at the time, so that the upper air outlet and the lower air outlet are realized; and closing the lower air duct after the upper air outlet and the lower air outlet are operated for a certain time (the time can be represented by a second time length), and only performing the upper air outlet.

When the air is independently discharged upwards, referring to the structure shown in fig. 2, cold air needs to be discharged through the lower air duct and the upper air duct, the air duct is long, and the problem of small air volume may occur. Therefore, the air outlet can be started under certain conditions, and the air outlet of the double air ducts is realized.
In some embodiments, the initial time may be determined according to an environmental parameter at the beginning of the upper air outlet mode, such as a temperature difference between an indoor environment temperature and a set temperature, and an operating parameter of the air conditioner, such as a wind gear.

And then, the opening time of the lower air duct can be determined, and after the opening time is reached, the lower air duct is closed and is converted into an upper air outlet mode again. Through the continuous repetition of the states, the continuous circulation of upward air outlet and upward and downward simultaneous air outlet is realized. Furthermore, when the lower air duct is opened simultaneously, the target frequency of the running of the compressor can be corrected to meet the cooling requirement.
It can be understood that the air outlet mode of the present embodiment may be specifically applied in a refrigeration or dehumidification mode, for example, if the user selects the refrigeration mode, the air outlet mode is executed according to the above procedure after the upper air outlet mode is set.
In this embodiment, through setting up the air-out mode, the not enough problem of travelling comfort that the air-out arouses down can be avoided. And moreover, by arranging the upper air duct and the lower air duct, air can be supplied to the upper air duct and the lower air duct simultaneously, the problems of slow temperature drop and poor refrigeration effect caused by only upper air outlet in a refrigeration mode are avoided, and the comfort of the air conditioner is improved.
