As shown in fig. 1, the air conditioner of the present invention has four air outlets, two air outlets are respectively disposed at the upper and lower portions of the air conditioner, each air outlet is provided with a baffle, and according to the difference "T" between the ambient temperature and the preset temperature of the air conditioner, which is detected and calculated after operating for a period of time in different cooling and heating modes, each baffle is automatically opened and closed by changing the control mode, the gear of the damper is adjusted, and the air supply mode is switched, so that the indoor room temperature can quickly meet the user's requirements.
When a user starts the machine, under the conditions of refrigerating and heating operation, the four baffles are all opened when the machine is just started to operate, the upper air outlet and the lower air outlet are all opened, the air supply mode is air outlet in two-up two-down mode at the moment, the indoor environment temperature is quickly adjusted, the current environment temperature starts to be detected after the machine operates for 3min, and the windshield gears are switched by calculating the difference value T between the environment temperature and the preset temperature.
The value range of T corresponding to each gear in the cooling mode is shown in fig. 2. When the wind shield is ultrahigh, the four baffles of the air conditioning device are all opened, so that an air supply mode of two upper parts and two lower parts is realized; when the wind is in a high wind gear, the second baffle plate 62 or the fourth baffle plate 64 is closed, so that a 'two-over-one-down' air supply mode is realized; when the wind is in the middle wind gear, the second baffle 62 and the fourth baffle 64 are closed, and the first baffle 61 and the third baffle 63 are kept in the opening state, so that a 'two-upper' air supply mode is realized; in low wind, only the first baffle 61 or the third baffle 63 is opened, and the rest are kept closed, so that an 'one-up' air supply mode is realized.
The value range of T corresponding to each gear in the heating mode is shown in fig. 3. When the wind shield is ultrahigh, the four baffles of the air conditioning device are all opened, so that an air supply mode of two upper parts and two lower parts is realized; in a high wind gear, the first baffle 61 or the third baffle 63 is closed, so that a 'two-next-upper' air supply mode is realized; when the wind is in the middle wind gear, the first baffle 61 and the third baffle 63 are closed, and the second baffle 62 and the fourth baffle 64 are kept in the opening state, so that a 'two-down' air supply mode is realized; in low wind, only the second baffle 62 or the fourth baffle 64 is opened, and the rest are kept closed, so that a 'one-shot' air supply mode is realized.
