As shown in fig. 10, the air conditioning module 2 is fixedly installed on the ceiling in this embodiment, the auxiliary air duct module 1 is located below the air conditioning module 2, and a receiving cavity 2112 for receiving the central portion 112 is provided in the bottom case 211. In order to prevent the auxiliary duct module 1 from coming off the air conditioning module 2, a stopper protrusion 31 is provided on both the central portion 112 and the bottom case 211.
The present embodiment includes a controller (not shown). The controller is used for receiving the control signal and outputting a control instruction to control the working states of the air conditioning module and the auxiliary air duct module.
The embodiment also provides a control method of the air conditioner, which comprises the following steps: the fan assembly of the air-conditioning module is started, and air enters the air conditioner from the air inlet of the air conditioner and is blown out from the fan blade air outlet. The auxiliary air duct module forms an extended air duct of the air conditioning module, and the air outlet effect of the air conditioning module is optimized.
And opening at least one air inlet baffle plate to communicate the air outlet of the air conditioner with the air inlets of the fan blades. The air inlet baffle (the air conditioner air outlet and the fan blade air inlet which are communicated) which can be opened according to the position selection of the user is suitable for the situation that the indoor space has few people and is in a specific position, the air outlet of the air conditioner can be concentrated in the position of the user, and the comfort level is improved.
Specifically, as shown in fig. 11, a control method of the air conditioner will be specifically described:
and S1, the controller receives a power-on signal and a mode signal. The mode signal includes signals of a cooling mode, a heating mode, a dehumidification mode, an air supply mode and the like. The starting signal and the mode signal are sent out by a remote controller, a wire controller or a control terminal and other equipment.
And S2, controlling the fan assembly to be started by the controller, and controlling the heat exchanger assembly to operate in a corresponding mode.
And S3, the controller receives an opening or closing signal of the air outlet of the air conditioner and controls the fan blade air inlet baffle to be in an opening or closing state.
The controller can also receive a set temperature signal, a set humidity signal and the like and control the working state of the air conditioning module according to the received signals. The mode, temperature and humidity control of the air conditioning module is the same as the control mode of the existing air conditioner, and the details are not repeated here.
In the process of operation S2 and S3, the process may enter S4 at any time, and the controller receives a shutdown signal to control the air conditioning module to shutdown.
The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention.
