The invention discloses a ceiling
machine and a control method thereof. The ceiling
machine comprises a shell, flow guide pieces and an air flow driving device; the shell is provided with a main air inlet, a plurality of main air outlets and a main air
flue used for communicating the main air inlet and the main air outlets; each flow guide piece comprises a plurality of air suction parts and a flow guide part, the flow guide part is detachably connected with the shell, the air suction parts extend to the main air outlets from the flow guide part, each flow guide piece is provided with an auxiliary air inlet, auxiliary air outlets and an auxiliary air
flue for communicating the auxiliary air inlet and auxiliary air outlets, and the auxiliary air inlet is communicated with the main air
flue; and the air flow driving device is used for driving air flow to enter the auxiliary air flue from the auxiliary air inlet. In the technical scheme, through the arrangement of an auxiliary air flue
system, the air flow direction is changed under the effect of the air pressure,
extrusion and friction between the air flow and a
solid are avoided, and therefore the
energy consumption of the air flow in the direction changing process is greatly reduced; and in this way, the
air volume is better improved, the air speed is kept, and a user can conveniently send air flow to a far designated spot.
