[0055] In the embodiment, each air duct 11 has an air inlet 112, and each air duct 11 is provided with an axial flow fan 113, and the axial flow fan blade 1131 of the axial flow fan 113 is rotatably arranged, so that the gas enters the air duct 11 from the air inlet 112 and flows out of the air duct 11 from the air outlet 111.

[0056] Specifically, the axial fan blade 1131 of the axial fan 113 rotates, so that the gas enters the air duct 11 from the air inlet 112, and flows out of the air duct 11 from the air outlet 111 after passing through the axial fan blade 1131. The axial fan 113 has the characteristics of large air volume and blowing spread shape leading to short blowing distance. When the air outlet 111 has the flow guide grille 30 arranged opposite to it, the air flowing out of the air outlet 111 flows to the air outlet 20 through the flow guide grille 30.

The flow guide grille 30 has a first position opposite to the air outlet 111 of the first air duct 114 and a second position opposite to the air outlet 111 of the second air duct 115.

[0059] Specifically, because the double-air-outlet structure is adopted, the thickness of the air outlet is large, and a person cannot avoid direct blowing of the air when sitting. By moving the flow guide grille 30 to the first position, the air outlet 111 of the second air duct 115 is not provided with the flow guide grille 30. The air outlet 111 of the first air duct 114 blows far air, and the air outlet 111 of the second air duct 115 blows near air. The user is basically not blown by the air at a distance of 2 to 3 meters, and can avoid direct blowing of the air. When the air conditioner is started in the cooling mode, the cold air sinks due to its heavy weight. Therefore, the flow guide grille 30 is moved to the first position, the cold air is transported to the far end through the air outlet 111 of the first air duct 114, and the cold air is transported to the near end for diffusion through the air outlet 111 of the second air duct 115. A three-dimensional air supply is formed, and the comfort is improved. When the air conditioner is started in the heating mode, the hot air floats due to its light weight. Therefore, the flow guide grille 30 is moved to the second position, and the hot air is transported to the far end through the air outlet 111 of the second air duct 115. During the transportation process, the hot air floats synchronously, and the heating comfort is improved.

[0060] In this embodiment, the air duct component 10 includes a mounting portion 13 and at least two air duct portions 14. The at least two air duct portions 14 are connected with the mounting portion 13, and each air duct portion 14 forms an air duct 11 and an air outlet 111. Each air duct portion 14 is detachably connected with the mounting portion 13, or each air duct portion 14 is integrally formed with the mounting portion 13.

[0062] The air conditioner provided by the application comprises a shell 2 and a panel 3, the panel 3 is connected with the shell 2 and a cavity is formed between the shell 2 and the panel 3, the panel 3 is provided with at least two air outlets 20, and the air conditioner further comprises the air duct assembly 1 in the above embodiment, and the air duct assembly 1 is arranged in the cavity.

[0063] The air conditioner provided by the application comprises a shell 2 and a panel 3, the panel 3 is connected with the shell 2 and a cavity is formed between the shell 2 and the panel 3, the panel 3 is provided with at least two air outlets 20, and the air conditioner further comprises the air duct assembly 1 in the above embodiment, and the air duct assembly 1 is arranged in the cavity.

[0064] Specifically, the air duct component 10 comprises a mounting portion 13 and at least two air ducts 14, the mounting portion 13 is used to mount the air duct component 10 in the air conditioner, and the air ducts 14 are used to form an air duct 11 and an air outlet 111, and an axial flow fan 113 is arranged in the air duct 11 to supply air to the air outlet 20 of the air conditioner.

[0065] In the embodiment, the main parts of the application include the panel 3, the air duct assembly 1, the shell 2, and the movable flow guide grid, wherein the flow guide grid 30 is movable up and down in front of the two air outlets 111 of the air duct 11, and the specific structure is as follows: the flow guide grid 30 is provided with a rack 52, the rack 52 is in gear rack engagement with a gear 51 provided on the driving member 40; at the same time, the flow guide grid 30 is provided with a guide part 33; the air duct 11 is provided with a guide groove 12, the guide part 33 on the flow guide grid 30 is matched with the guide groove 12, and the air duct assembly 10 is provided with a first limiting member 70 and a second limiting member 80; the driving member 40 is driven by the main board power supply to rotate the gear 51, the gear 51 is in gear rack engagement with the rack 52 provided on the flow guide grid 30, and finally drives the flow guide grid 30 to move up and down. When the flow guide grid 30 moves up and down to the position, the flow guide grid 30 is in contact with the first limiting member 70 and the second limiting member 80 provided on the air duct assembly 10 to limit the position, and determine that the flow guide grid 30 coincides with (i.e., is relatively arranged with) the air outlet 111. The flow guide grid 30 is switched in the up and down air outlets, and the problem of far and near air adjustment of the axial flow fan air conditioner with a double air outlet structure is solved.

[0066] From the above description, it can be seen that the above-mentioned embodiments of the application achieve the following technical effects:

When the flow guide grid 30 is arranged relative to the air outlet 111, the air flowing out of the air outlet 111 flows out of the air outlet 20 after passing through the flow guide grid 30, and the air blowing distance of the air outlet 20 is far after passing through the flow guide grid 30. The air outlet 111 is directly connected with the air outlet 20, which means that the air flowing out of the air outlet 111 does not pass through the flow guide grid 30 but directly passes through the air outlet 20, and the air blowing distance of the air outlet 111 is short. It can be seen that the air duct assembly can change the air blowing distance of the air outlet by arranging the movable flow guide grid 30, which solves the problem that the air duct assembly in the prior art cannot change the air blowing distance, and at least two air outlets can have different air blowing distances, improving the air blowing diversity and comfort.

[0069] Spatially relative terms, such as "beneath", "below", "lower", "above", "upper" and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device described is turned over in use, a downwardly-facing surface can then be oriented upwardly, and vice versa. Thus, the example term "below" can encompass both an orientation of below and above. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. The terms "first", "second", "third", etc., do not necessarily indicate any ordinal, chronological or other sequence unless expressly so defined by the relative terms or context.

[0070] The specific embodiments of the present application have been shown and described in order to illustrate the application. It will be understood by those skilled in the art that various modifications can be made to the embodiments without departing from the scope of the present application. Thus, the present application is not intended to be limited to the embodiments described herein but is to be accorded the full scope of the claims, and legal equivalents thereof, encompassing any modifications made available by the application.
