The air conditioner of the prior art has a false air outlet on both sides of the main air outlet, that is, a portion where the cross-flow vane leaves are formed on both sides of the front panel, and a dead angle of the air is formed at the position where the false air outlet is located. In a specific embodiment of the present invention, the fan assembly 3 is disposed in a groove at the false air vent on the side of the main air outlet 1 to construct two independent air passages, and the position of the secondary air outlet 2 is opposite to the false air vent Corresponding. This arrangement can make full use of the structural features and spatial position of the existing air conditioning equipment, reduce the complexity of the installation of the wind turbine assembly 3, and change the original air supply dead angle to the secondary air outlet 2 that can truly achieve the wind, and does not need to The housing structure and internal layout of the existing air-conditioning equipment are changed too much, and the air supply angle and the air supply area can be increased to a certain extent, and multi-angle air supply can be realized.

This embodiment can realize the oscillating air supply through the sub air outlet 2 by a relatively simple structure. Preferably, the air outlet of the fan assembly 3 is reciprocally oscillating in a plane perpendicular to the air outlet. Most of the existing air conditioning devices have a mode of oscillating air through the main air outlet. Therefore, in the air supply mode that can be selected in the embodiment of the present invention, the main air outlet 1 and the secondary air outlet 2 can be selected and fixed at the same time. The air is supplied from the angle or the air is oscillated up and down, and one of the main air outlet 1 and the sub air outlet 2 can be selected to swing the air.

The motor 33 is preferably a stepping motor, which can realize position control more accurately, thereby driving the fan 31 to rotate in a vertical plane perpendicular to the longitudinal direction of the air outlet to realize dynamic multi-angle air supply through the auxiliary air outlet 2.

For the above embodiments, the fan 31 can be selected in different forms, such as a centrifugal fan or an axial fan, and can be selected according to various requirements such as installation space, air volume, and wind pressure.

A centrifugal fan is installed in the air outlet structure of the air conditioner shown in Fig. 3. The centrifugal fan can change the flow direction of the wind inside the air duct. As can be seen from the schematic diagram of the air outlet direction shown in Fig. 2, when the air conditioner is working, the main air outlet 1 is ventilated along the arrow A (swinging in a fixed direction or up and down), and at the same time, the centrifugal fan will be the main air outlet. 1 The wind flowing through the evaporator in the corresponding area is sucked to the side of the main air outlet 1 along the arrow B, and the wind direction is changed by 90° in the centrifugal fan, and then the air is discharged from the sub air outlet 2 along the arrow C. The centrifugal fan can better meet the flow demand of the wind, and the air volume and wind pressure can be realized by the centrifugal fan, so that the auxiliary air outlet 2 fully functions when the air conditioning equipment works, and further strengthens the cooling and heating of the air conditioning equipment. effect.

In another embodiment, the fan can be an axial fan, and the axial direction of the axial fan is parallel to the axis. Since the fan cannot change the flow direction of the wind, it is better to install a suitable installation angle according to requirements. The wind in the region corresponding to the main tuyere 1 is smoothly sucked to the side of the main air outlet 1 to achieve a similar effect to the centrifugal fan.

In addition, the present invention also provides an air conditioning apparatus comprising the air outlet structure of the air conditioning apparatus described in the above embodiments. Preferably, the air conditioning device is a wall-mounted air conditioner. The air conditioning device can cooperate with the air supply through the main air outlet 1 and the auxiliary air outlet 2, firstly, because the air supply wide angle is increased, the air outlet angle can be minimized, and the air can be simultaneously supplied in multiple directions, thereby enabling the air volume to be achieved. The speed of filling the room becomes faster, thereby improving the cooling and heating performance of the air-conditioning equipment; secondly, due to the increase in the overall area of the air outlet, When the air supply amount is constant, the uniformity of the air supply in the room can be improved and the wind speed can be reduced to improve the user's comfort feeling.

For a specific type of embodiment, the air conditioning device has a cooling and heating mode, and a wind deflector is disposed at the main air outlet 1 , and the main air outlet 1 can realize the reciprocating swing air supply in a plane perpendicular to the air outlet. A centrifugal fan is respectively disposed on both sides of the main air outlet 1, and an outlet of the centrifugal fan is used as the auxiliary air outlet 2, and the centrifugal fan can be rotated by the motor 33 to swing up and down through the auxiliary air outlet 2. For the air conditioning apparatus of this type of construction, several preferred modes of operation are given below.

Among them, in a cooling mode, the main air outlet 1 is horizontally blown, and the auxiliary air outlet 2 is blown downward, which can achieve a three-dimensional wraparound effect of the entire room, thereby improving the cooling speed. In another cooling mode, the main air outlet 1 and the auxiliary air outlet 2 simultaneously oscillate the air supply, for example, swinging the air up and down, and the wind turbine 31 is achieved under the premise that the air guiding effect is ensured by the air guiding plate corresponding to the main air outlet 1 Similar to the air supply function of the air deflector, the air conditioner can realize the dynamic air as a whole, and avoid the cold wind blowing in a fixed direction as much as possible, thereby improving the comfort feeling of the human body. In the heating mode, the main air outlet 1 is blown downward, and the auxiliary air outlet 2 is horizontally blown or oscillated up and down.
