With the diversification of air outlet modes of air conditioners, especially the development of air conditioners with switchable upper and lower air outlets, the original filter screen can effectively filter the incoming air flow when the corresponding air outlet is used as the air inlet, but when the same air outlet is switched to the air outlet, the existence of the existing filter screen increases the wind resistance of the outgoing air flow, resulting in a decrease in the air outlet performance of the air conditioner. Based on this phenomenon, the present invention is proposed. Summary of the invention

[0025] See also Figures 1 to 6 As shown, according to an embodiment of the present invention, there is provided an air outlet assembly, comprising an air outlet housing 1 having a flow area and a filter 2 mounted on the air outlet housing 1, wherein the filter 2 has a filtering position corresponding to when the air outlet assembly is used as an air inlet and can filter the incoming air flow, and a deflection position corresponding to when the air outlet assembly is used as an air outlet and forms an angle with the filtering position, wherein the angle can be preset or selected and set in real time according to actual needs. In this technical solution, the filter has a filtering position and a deflection position forming a certain angle with the filtering position, so that the air outlet assembly can be switched according to the different functions it realizes. Specifically, when the air outlet assembly is used as an air inlet, the filter is placed in the filtering position, thereby realizing efficient filtering of the incoming air flow, and when the air outlet assembly is used as an air outlet, the filter is placed in the deflection position, thereby reducing the wind resistance formed by the filter on the outgoing air flow, so that the technical solution of the present invention is particularly suitable for air conditioners with switchable inlets and outlets.

[0026] As an optional embodiment, the filter element 2 includes a filter screen 21 and a rotating shaft 22, the filter screen 21 and the rotating shaft 22 are connected as a whole, and the filter screen 21 is pivotally connected to the air outlet housing 1 through the rotating shaft 22. It can be understood that when the driving device is used to drive the rotating shaft 22 to rotate, the rotating shaft 22 will drive the filter screen 21 connected thereto to rotate and thus form the angle, thereby making it easier to switch the position of the filter screen 21.

[0027] Furthermore, the filter 21 includes a plurality of filter sub-bodies. When the filter element 2 is in the filtering position, the plurality of filter sub-bodies can be flatly covered on the flow area, that is, the filter element 2 is composed of a plurality of filter sub-bodies assembled together. In this way, when each of the filter sub-bodies is set to be driven individually, any one of the plurality of filter sub-bodies can be independently driven to a deflection position, so that the outlet airflow can be filtered as necessary. For example, the filter is a composite filter that can purify the air (for example, to remove harmful impurities and particles such as formaldehyde and PM2.5). Part of the filter sub-bodies can be controlled to be in the filtering position and the remaining filter sub-bodies can be controlled to be in the deflection position, so that while achieving air purification, the wind resistance to the outlet airflow can be reduced to a certain extent. Of course, the filter sub-bodies in the deflection position can also guide the outlet airflow to a certain extent.

[0028] In the case where the filter 21 has a plurality of filter sub-bodies, it is best that the plurality of filter sub-bodies each have a corresponding rotating shaft 22. At this time, each rotating shaft 22 is independently connected to a corresponding driving motor 24, so that each filter sub-body can be switched to a separate position, thereby achieving the purpose of filtering and purifying the flow area in a divided area when the air outlet assembly is used as an air outlet.

[0029] As another feasible embodiment, preferably, a crankshaft 23 is provided on the rotating shaft 22, and also includes a connecting rod 3. The crankshafts 23 respectively possessed by the multiple filter mesh bodies are all connected to the connecting rod 3. The setting of the connecting rod 3 can realize the linkage of multiple rotating shafts 22. At this time, the power output end of the driving motor 24 is drivingly connected to the crankshaft 23 possessed by any one of the multiple filter mesh bodies; or, the power output end of the driving motor 24 is drivingly connected to the connecting rod 3.

[0030] In order to achieve the aforementioned purpose of regional filtration and purification, preferably, the connecting rod 3 is multiple, and the multiple connecting rods 3 are respectively connected to at least two of the crankshafts 23 of the multiple filter mesh bodies. That is, at this time, the driving motor 23 also has multiple corresponding ones, and the specific number can be consistent with the number of the connecting rods 3.

[0031] In order to reduce the number of assembled parts of the air outlet assembly as much as possible, thereby improving the assembly efficiency and operation and maintenance costs of the air outlet assembly, the filter mesh body includes a filter core 211 and a frame 212 arranged around the filter core 211, and the frame 212 is integrally injection molded with the rotating shaft 22; and / or the rotating shaft 22 and the crankshaft 23 are integrally injection molded.

[0032] Furthermore, the axial end surface of the tuyere housing 1 is provided with a plurality of grooves 11, and the grooves 11 extend along the axial direction of the tuyere housing 1. The rotating shaft 22 can be assembled in the grooves 11 and can pivot. Compared with the prior art that a through hole is provided on the tuyere housing and the insertion assembly is realized by the elastic deformation of the rotating shaft, the groove 11 in the present invention can easily load the rotating shaft 22 because of the opening facing the assembler. The groove 11 can be, for example, a common U-shaped groove. In this case, after the corresponding position of the rotating shaft 22 is loaded, the opening of the U-shaped groove needs to be subjected to necessary anti-slip treatment, for example, a crossbeam is added at the opening for blocking. As a better embodiment, preferably, the groove 11 is a constriction structure, and the constriction has a certain elasticity. The loading of the rotating shaft 22 depends on the deformation after the pressure is applied. Specifically, the tuyere housing 1 is mostly an injection molded part, which itself has a certain amount of elastic deformation.

[0033] An annular groove 221 is provided on the shaft body corresponding to the pivotal connection between the rotating shaft 22 and the groove 11. The annular groove 221 can effectively store the silicone grease oil therein for a long time, thereby preventing the silicone grease oil from being squeezed out from the matching position during long-term operation, and improving the lubrication effect of the moving matching surface.

[0034] According to an embodiment of the present invention, there is also provided an air conditioner, comprising the above-mentioned air outlet structure.

[0035] It is easy for those skilled in the art to understand that the above-mentioned advantageous methods can be freely combined and superimposed without conflict.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
