The indoor unit of air conditioner has evolved from a cabinet unit and a wall-mounted unit to a ceiling-buried type that does not require land occupation. Because of its good adaptability and aesthetics of air-conditioning installation, the ceiling-buried type has gradually become the mainstream of high-end residences.

Existing air-conditioning units with four-way venting are all centrifugal fans. Due to the suction of the centrifugal fan in the body, the indoor air enters the body through the air inlet grille in the center of the bottom panel, and then enters the centrifugal fan, and then blows to the surrounding air conditioners. Heater, exchange heat with it, and finally blow out through the four long strip air outlets on the bottom panel, and so on. Since the air inlet and the return air are located close to each other, when such a layout is in the heating condition, the airflow is prone to short-circuit, which affects the heating effect.

In addition, in the existing ceiling-mounted air conditioner, the air outlet direction of the air outlet is not adjustable, thus resulting in a single air outlet direction and poor user experience.
