In some embodiments, controlling rotation of the hollow annular body 21 relative to the scroll case 31 in response to a cool air mode or a dehumidification mode in an operation mode of the mobile air conditioner further includes: controlling the fan to rotate at a third rotating speed in response to the cold air mode; and in response to the dehumidification mode, controlling the fan to rotate at a fourth rotating speed, wherein the fourth rotating speed is greater than the third rotating speed.
In some embodiments, in response to a wind sweeping mode in the operation mode of the mobile air conditioner, the scroll casing 31 is controlled to swing up and down with respect to the casing 10 about an axis parallel to the rotation axis of the hollow annular body 21 to adjust the wind outlet angles of the first and second wind outlets.
For example, after the air conditioner is turned on, the control system in the mobile air conditioner detects an operation mode signal and a sweeping gear signal, wherein the operation mode signal is used for controlling the third motor 23 driving the hollow annular body 21 to rotate, the sweeping gear signal is used for controlling the first motor 344 of the air duct assembly, and the operation mode is not affected by the sweeping gear signal, i.e. the user does not affect the sweeping gear when switching the operation mode, and the operation mode is not affected when switching the sweeping gear.
The operation modes are divided into an air supply mode, a cooling mode and a dehumidifying mode. The air supply mode is that only a fan in the refrigerating system operates, air is sucked from two sides and blown out forwards and backwards, and in the air supply mode, the third motor 23 does not act, and front and rear air outlet is dehumidified when passing through the hollow annular body 21.
In the refrigeration mode, the compressor 43 is started, the refrigeration system operates normally, the fan sucks air from two sides, indoor air is respectively processed into cold air and hot air after passing through the evaporator 41 and the condenser 42, the cold air is absorbed by the hollow annular body 21 to remove moisture and blown forward, the hot air passes through the hollow annular body 21 to blow the moisture in the dehumidification filler to dry and discharge the moisture backward, the regeneration of the dehumidification filler is completed, and the corresponding airflow direction is shown in the figure 5; at this time, the hollow annular body 21 will rotate under the action of the third motor 23, the dehumidified filler will be turned to the cold air outlet (first air blowing port) to wait for the next moisture absorption, and the dehumidified filler will be turned to the hot air outlet (second air blowing port) to wait for regeneration, so that the dehumidification can be circulated.
In the dehumidification mode, the compressor 43 is started as well, but the rotation speed of the fan is increased, the front and rear air output is increased, the rotation speed of the corresponding hollow annular body 21 is increased, and under the condition, dehumidification and regeneration are completed more quickly, and the dehumidification amount of the whole mobile air conditioner is higher.
The wind sweeping gear is divided into a wind sweeping-free gear, a wind sweeping low gear and a wind sweeping high gear, wherein the wind channel driving motor does not act when the wind sweeping is not performed, and the wind channel driving motor operates according to the angle before the last shutdown; in the low wind sweeping gear, the wind channel driving motor (the first motor 344) starts to drive the supporting shell 34 and the volute 31 to rotate clockwise or anticlockwise around the rotation center, the rotation limiting angle can be 5 degrees, the total rotation angle can be 10 degrees, and the angle offset when the wind channel rotates can be shown in fig. 6; when the upper wind sweeping gear is selected, the first motor 344 drives the supporting shell 34 and the volute 31 to reciprocate within the rotation limit angle at a higher speed, so that the upper and lower wind sweeping effects are enhanced. The first power-on can be performed in a high-grade mode by default in the refrigeration mode and the wind sweeping gear, if the operation mode or the wind sweeping gear is adjusted by a user button in the use process, the operation mode corresponding to the third motor 23 and the first motor 344 can be switched under the corresponding conditions, the current operation mode can be reserved when the system is powered off, and the system is operated in the mode when the system is powered on next time. If the power is cut off midway, the air-sweeping high-grade operation is performed according to a default refrigeration mode.
