As shown in fig. 1-5, the present invention provides an air duct assembly, the overall structure of which is similar to "S" as shown in fig. 1, and which includes an assembly body 2 for accommodating a centrifugal fan 3 and a flow guide ring 1 fixedly disposed at an air inlet 21 of the assembly body 2, the flow guide ring 1 and the assembly body 2 are integrally formed, and no seam exists between the two, so that smooth air inlet can be ensured during use, and no additional vortex and wind noise are generated when air flows through the flow guide ring 1; in addition, because the guide ring 1 and the assembly body 2 are integrally designed, the reliability of the structure can be improved and the assembly efficiency can be improved during assembly.

Specifically, the guide ring 1 and the assembly body 2 can be formed by integral injection molding.

In order to ensure that the air flow at the air inlet 21 can smoothly flow and reduce the wind noise, the outer ring of the guide ring 1 is fixedly connected with the air inlet 21 of the assembly body 2, the inner ring of the guide ring extends towards the inner side of the air inlet 21, and the air flows from the outer ring of the guide ring 1 towards the inner ring when flowing in.

Specifically, in order to reduce the loss of the air flowing through the air duct, the inner side wall of the air duct should avoid the existence of corners as much as possible, so the inner side wall of the air duct preferably has an arc-shaped structure and the arc-shaped structure is matched with the flowing direction of the air.

It should be noted that the air duct may be formed by integrally forming with the assembly body 2, or may be fixedly disposed together by post-assembling.

As an alternative embodiment, one end of the air duct is connected to the assembly body 2, and the other end extends in a direction away from the assembly body 2, and when the centrifugal fan 3 is operated, air flows into the air duct through the centrifugal fan 3.

As an optional implementation manner, as shown in fig. 2, when the cover plate 5 covers the air duct, an air outlet 6 for air to flow out is reserved at a connection between the upper end and the lower end of the air duct and the cover plate 5, the air flows into the assembly body 2 through the flow guiding ring 1 under the action of the centrifugal fan 3 and then flows out from the air outlet 6, and the air outlet 6 is located at the upper end and the lower end of the cover plate 5. In addition, the air outlet 6 can also be arranged at the air outlet end of the air duct, and the cover plate 5 can just cover the air duct.

It should be noted that the upper duct 41 and the lower duct 42 are symmetrical with respect to the center of the fitting body 2 as a point of symmetry.

Considering different service environment, this wind channel subassembly needs to possess three kinds of different air-out modes: only the upper end air outlet 6 is used for air outlet, only the lower end air outlet 6 is used for air outlet, and the air outlets 6 at the upper end and the lower end are used for air outlet simultaneously. In order to meet the above requirements, as an alternative embodiment, an upper partition capable of opening or closing the upper duct 41 is provided on the upper duct 41, and/or a lower partition capable of opening or closing the lower duct 42 is provided on the lower duct 42.

(2) when the air conditioner operates in the heating mode, hot air can be blown out from the lower air outlet 6 by closing the upper air duct 41 by the upper partition plate and opening the lower air duct 42 by the lower partition plate;

(3) the air conditioner can also open the upper air outlet 6 and the lower air outlet 6 simultaneously to realize the air outlet of the indoor unit of the air conditioner, and the indoor temperature is respectively uniform.

It should be noted that, the above design can avoid the gas from flowing back at the other air outlet 6, thereby improving the heat exchange efficiency of the air conditioner and reducing the cost and energy consumption. Meanwhile, the air duct assembly is not only suitable for an air conditioner indoor unit, but also suitable for an air duct machine air conditioning system due to the same internal structure.

Under the prerequisite that the assurance can control the break-make of wind channel 41 and lower wind channel 42, go up the concrete position that baffle and lower baffle set up and can be in being close to air outlet 6 department, also can be in being close to centrifugal fan 3 department, however, compare, be close to air outlet 6 and set up and can hold partly air in the wind channel that can make to close, and then cause partly air thermal waste, consequently, the priority considers to go up the baffle and lower baffle setting and is close to centrifugal fan 3 one side in the wind channel.

For convenience of control, the first hinge shaft and the second hinge shaft may be controlled by a motor or the like to control the opening and closing of the upper duct 41 and the lower duct 42 in such a manner as to drive the upper partition and the lower partition to rotate.

It should be noted that the clockwise rotation or the counterclockwise rotation of the centrifugal fan 3 may cause the inclination direction of the air duct to be different, that is, the rotation direction of the centrifugal fan 3 may affect the specific shape of the upper air duct 41 or the lower air duct 42.
