The utility model discloses utilize the magnus principle to carry out the wind-guiding, can be so that the air-out angle control range of machine in the air conditioning is close 180, realize that the whole room does not have the dead angle air supply, improve user experience and feel.

The magnus effect is a phenomenon that when a rotation angular velocity vector of a rotating object is not coincident with an object flying velocity vector, a transverse force is generated in a direction perpendicular to a plane formed by the rotation angular velocity vector and a motional velocity vector, and the flying path of the object deflects under the action of the transverse force. The rotating object can generate a force in the transverse direction because the object rotates to drive surrounding fluid to rotate, so that the fluid speed on one side of the object is increased, and the fluid speed on the other side of the object is reduced. According to bernoulli's theorem, an increase in fluid velocity will result in a decrease in pressure, which will result in an increase in pressure, which will result in a pressure difference across the rotating object and create a lateral force, while this force primarily changes the direction of the flying velocity, i.e. creates a centripetal force in the motion of the object, which will result in a change in the flying direction of the object, since the lateral force is perpendicular to the direction of motion of the object. In the same principle, if the object is fixed and the rotational force is applied to keep it rotating while a horizontal incoming flow is applied, the rotating object will change the direction of the horizontal incoming flow.

Specifically, the wind guide post 5 rotates clockwise in the airflow direction shown in fig. 3, the flow rate is high and the pressure is low because the upper half airflow of the wind guide post 5 is in the same direction as the rotation direction of the wind guide post 5, and the flow rate is low and the pressure is high because the lower half airflow of the wind guide post 5 is in the opposite direction to the rotation direction of the wind guide post 5. Therefore, when the fixed position of the air guide column 5 is fixed, the direction of the horizontal incoming flow is changed to a place with small pressure by the action of the pressure intensity when the horizontal incoming flow passes through the air guide column 5 and the upper half part of the air flow passing through the air guide column 5; similarly, the lower half of the air flow passing through the air guide column 5 will also be deflected to a place where the pressure is low, due to the slow speed and high pressure of the air flow.

The utility model changes the air outlet direction of the air conditioner by using the magnus effect principle, and can deflect the air outlet of the air conditioner even if no air guide column or air guide blade 19 is arranged, thereby realizing the air guide effect; the position that operating personnel accessible lift actuating mechanism adjusted air guide column 5 and then realize realizing the diversified regulation to the air-out direction, realizing diversified air-out mode, improving user experience.

Specifically, in the air conditioning indoor unit 100 provided in this embodiment, indoor air enters the heat exchange cavity 18 through the air inlet 122, and after heat exchange by the indoor heat exchanger 2, the indoor air enters the air outlet duct 4 under the action of the indoor fan 3, and when an airflow in the air outlet duct 4 flows to the air guide post 5, and the air guide post 5 rotates clockwise or counterclockwise, based on the magnus effect, the rotation of the air guide post 5 changes the flow rates of the upper half airflow and the lower half airflow of the air guide post 5. Because the initial flowing direction of the upper half part of the airflow flowing to the wind guide post 5 is consistent with the initial flowing direction of the lower half part of the airflow, the rotation of the wind guide post 5 inevitably enables the flowing direction of one part (the upper half part or the lower half part) of the airflow to be consistent with the rotating direction of the wind guide post 5, and the airflow has high flow speed and low pressure; the other part (lower half or upper half) of the airflow has a flow direction opposite to the rotation direction of the wind guide post 5, and the airflow has a low flow speed and a high pressure. The difference between the airflow direction and the rotation direction of the air guide column 5 further causes the flow speed and pressure of the upper half part and the lower half part to change, so that the airflow around the periphery of the air guide column 5 forms a flow speed difference and a pressure difference, and the airflow passing through the air guide column 5 can deflect and change direction to a place with small pressure based on the pressure difference and then flows out to the indoor through the air outlet 14.
