The first air outlet nozzle 111 and the second air outlet nozzle 112 are mounted on the mounting surface of the air outlet cavity 113 and located on two sides of the mounting surface, and the bearing 15 is arranged on the other surface of the mounting surface, so that the wind shield 14 can be attached to the through hole communicated between the first air outlet nozzle 111 or the second air outlet nozzle 112 and the air outlet cavity 113 as much as possible; the area of the mounting plate is half of the mounting surface of the air outlet cavity 113, and when the wind shield 14 rotates to one side of the first air outlet nozzle 111, the communication between the first air outlet nozzle 111 and the air outlet cavity 113 is ensured to be stably cut off; when the wind deflector 14 rotates to one side of the second air outlet nozzle 112, the communication between the second air outlet nozzle 112 and the air outlet cavity 113 is stably cut off.
When the wind deflector 14 moves to the position where the first air outlet nozzle 111 is connected with the air outlet cavity 113, the communication between the first air outlet nozzle 111 and the air outlet cavity 113 is cut off, so that fresh air in the outdoor environment can be discharged into the second air duct only from the second air outlet nozzle 112; when the wind deflector 14 moves to the position where the second outlet air is connected to the air outlet cavity 113, the communication between the second air outlet nozzle 112 and the air outlet cavity 113 is cut off, so that fresh air in the outdoor environment can be discharged into the first air duct only from the first air outlet nozzle 111. Therefore, in this embodiment, when the user controls the air conditioner to operate in the dual-temperature-zone mode, the user can further select the serial number of the air outlet corresponding to the high-temperature zone, when the high-temperature zone corresponds to the first air duct, the controller controls the air baffle 14 to move to the position where the second air outlet nozzle 112 is connected to the air outlet cavity 113, and when the high-temperature zone corresponds to the second air duct, the controller controls the air baffle 14 to move to the position where the first air outlet nozzle 111 is connected to the air outlet cavity 113, so that the intelligence degree and wide adaptability of the air conditioner of the present invention are improved, and more setting requirements of the user are met.
Further, referring to fig. 9, fig. 9 is a flowchart illustrating a third embodiment of the control method according to the present invention based on the first embodiment, and step S20 includes:
step S24: when the operation mode is a single-temperature-zone mode, judging whether the air exchange mode of the air conditioner is started;
step S25: when the air exchange mode is started, the fan assembly 10 is controlled to be started, and the wind shielding part is controlled to rotate so as to simultaneously conduct the channels between the fan assembly 10 and the first air channel and between the fan assembly 10 and the second air channel;
step S26: when the ventilation mode is closed, the fan assembly 10 is controlled to be closed.
As another embodiment, when the user controls the air conditioner to operate in the single temperature zone mode, the user may further control whether the air conditioner starts a ventilation mode, and when the ventilation mode is started, the wind deflector 14 rotates to a middle position, that is, the wind deflector 14 is perpendicular to the mounting surface of the air outlet cavity 113, and then the first air outlet nozzle 111 and the second air outlet nozzle 112 are simultaneously turned on. When the ventilation mode is off, the controller directly controls the fan assembly 10 to turn off. Therefore, the air exchange requirement of a user is met, and the compatibility and the wide applicability of the air conditioner are further improved. .
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
