For avoiding redundant description, in the following embodiments, the air guiding device 200 is mainly applied to the indoor unit 100 of the air conditioner for explanation, and other types can be referred to for implementation.

Referring to fig. 2 and fig. 3, in an embodiment of the air guiding device 200 of the present invention, the air guiding device 200 includes an air outlet frame 210, a driving device 300, and a plurality of air guiding components (such as an air guiding plate 220 or a louver 230). The air-out frame 210 has a rotation axis, and the air-out frame 210 is rotatable around the rotation axis; the air-out frame 210 further has a first end 201 and a second end 202 opposite to each other. The driving device 300 is installed between the first end 201 and the second end 202 of the air-out frame 210. The plurality of air guides are arranged on the air outlet frame 210 in a swinging manner and are respectively arranged on two sides of the driving device 300; the plurality of air guides are connected to the driving device 300 to be driven by the driving device 300 to swing.

Specifically, the rotation axis of the air-out frame 210 is a virtual axis for describing the rotation center of the air-out frame 210, i.e. the air-out frame 210 can rotate around the rotation axis. The air-out frame 210 is formed with a first vent and a second vent at opposite sides of the rotation axis, the first vent and the second vent being in communication. The air outlet frame 210 is driven to rotate, the first ventilation opening and the second ventilation opening can be exchanged, and then the air outlet of the air outlet frame 210 is switched. The outer end faces of the first end portion 201 and the second end portion 202 of the air outlet frame 210 are provided with a rotation shaft 203, and the extension direction of the rotation shaft 203 corresponds to the rotation axis. The air outlet frame 210 can be rotatably installed in an air outlet duct of the indoor unit 100 of an air conditioner or other air cleaning equipment by the rotating shaft 203.

The driving device 300 is installed between the first end 201 and the second end 202 of the air-out frame 210, that is, a gap is formed between the driving device 300 and the first end 201 of the air-out frame 210, and a gap is also formed between the driving device 300 and the second end 202 of the air-out frame 210. Part of the air guide is located between the driving device 300 and the first end 201 of the air-out frame 210, and the other part of the air guide is located between the driving device 300 and the second end 202 of the air-out frame 210. Therefore, the distances between the two air guides and the driving device 300 are not too different, so that the driving device 300 can provide substantially equivalent torques for the air guides on the two sides of the driving device 300, and the air guides can swing stably.

For the specific position of the driving device 300, the driving device 300 may be located at the middle position of the air-out frame 210, or at the upper position of the middle part, or at the lower position of the middle part. In this case, it is preferable that the driving device 300 is located in the middle of the air-out frame 210, and the distance between the driving device 300 and the first end 201 of the air-out frame 210 is the same as the distance between the driving device 300 and the second end 202 of the air-out frame 210. Therefore, the air guide pieces can be driven to swing stably, the gravity center of the air outlet frame 210 is low, the air outlet frame 210 is not prone to lateral dumping, and the balance of the air outlet frame 210 is enhanced.

According to the technical scheme of the invention, the driving device 300 is arranged between the first end 201 and the second end 202 of the air outlet frame 210, the plurality of air guides are respectively arranged at two sides of the driving device 300, namely the driving device 300 divides the plurality of air guides into two parts, so that the distance between the driving device 300 and the farthest air guide in the air guides of each part is not too large, the torques provided by the driving device 300 for the air guides at two sides of the driving device 300 are basically equivalent, further, the air guides swing more stably, and the stability of the swinging of the air guides is enhanced.

To facilitate understanding of the air-out frame 210, the air-out frame 210 will be described first.

Referring to fig. 2 and 3, in an embodiment, the air outlet frame 210 has a first air vent and a second air vent located at two opposite sides of the rotation axis, and the first air vent and the second air vent are communicated. The air guide of the air-out frame 210 may be disposed corresponding to the first ventilation opening, and may also be disposed corresponding to the second ventilation opening. When the air conditioning indoor unit 100 works, the air outlet frame 210 is driven to rotate by 180 degrees, and the positions of the first ventilation opening and the second ventilation opening can be exchanged, so that the air outlet of the air outlet frame 210 is switched, and the air supply mode is changed.

When the air-out frame 210 rotates to the position where the first ventilation opening faces inward and the second ventilation opening faces outward, the airflow blown out from the air-out duct of the indoor unit 100 of the air conditioner firstly enters the air-out frame 210 through the first ventilation opening, then flows to the second ventilation opening after being guided by the air guide member, and finally is blown to the air outlet 102 through the second ventilation opening.

When the air-out frame 210 rotates to the position where the second ventilation opening faces inward and the first ventilation opening faces outward, the airflow blown out from the air-out duct of the indoor unit 100 of the air conditioner firstly enters the air-out frame 210 through the second ventilation opening, then flows to the first ventilation opening after being guided by the air guide member, and finally is blown to the air outlet 102 from the first ventilation opening.

In an embodiment, the air outlet frame 210 includes a frame 211 and two side plates 212 installed at two opposite sides of the frame 211, and an air outlet cavity communicating the first air vent and the second air vent is defined between the two side plates 212. That is, the air-out frame 210 includes three portions, namely, a frame 211 and two side plates 212, and the frame 211 is formed with a first ventilation opening and the second ventilation opening. After the frame 211 and the two side plates 212 are respectively manufactured and molded, the two side plates 212 are respectively mounted on the left and right sides of the frame 211, so as to be assembled with the frame 211 to form the air outlet frame 210. Wherein, an air outlet cavity of the air outlet frame 210 is defined between the two side plates 212.
