The specific structure of the air deflection panel 100 will be mainly described below.

Referring to fig. 1 to 2, in the embodiment of the present invention, the air deflector 100 is used in an air conditioning indoor unit,

the air guide plate 100 includes:

the air guide body 130 is provided with a windward side 110 and a leeward side 120, and the windward side 120 faces an air outlet of the indoor unit of the air conditioner;

the rotating bracket 200, the rotating bracket 200 is arranged on the windward side 110 of the wind guide body 130;

and the sealing rib 140 is arranged on the windward side close to the rotating axis of the rotating bracket 200.

Specifically, in the present embodiment, the air deflector 100 is rotatably connected to the housing of the air conditioner, and the face frame 700 of the air conditioner is fixedly connected to the housing. The shell is provided with an air inlet, an air outlet and an air channel communicated with the air inlet and the air outlet. The rotating bracket 200 includes a bending portion, one end of the rotating bracket 200 is fixedly connected to the air guiding body 130, and the other end extends from the windward side of the air guiding body 130 to the casing of the air conditioner. The rotating bracket 200 is provided with a rotating hole, the rotating bracket 200 is rotatably connected with the casing of the air conditioner through the rotating hole, and the rotating axes of the air deflector 100 and the rotating bracket 200 are the axes of the rotating hole. Taking the case that the rotating bracket 200 is rotatably connected to the housing at the lower portion of the air outlet, at this time, the axis is close to the lower side of the air outlet, and the sealing rib 140 is disposed at the position of the air deflector 100 close to the lower side of the air outlet. Of course, in some embodiments, the sealing rib 140 may be integrally formed with the wind guide body 130. The cross-sectional shape of the sealing rib 140 may be various, such as triangular, circular, polygonal, etc., and in this embodiment, a rectangular shape is taken as an example. In the process of rotating the air deflector 100 to guide air, the sealing rib 140 extends into the gap between the air deflector 100 and the face frame 700 to block the air flow after heat exchange from flowing through the gap. The lower sealing rib 140 is an elongated rectangular plate, and the sealing rib 140 is disposed along the length direction of the air deflector 100, so that the sealing rib 140 seals the whole gap in the length direction.

In this embodiment, when the air deflector 100 rotates to guide air, the sealing rib 140 blocks the gap between the air deflector 100 and the face frame 700, so that the air flow after heat exchange in the air duct cannot flow through the gap between the air deflector 100 and the face frame 700, thereby avoiding the condensation phenomenon caused by too large temperature difference between the windward side and the leeward side of the air deflector body 130, and being beneficial to better use of the air conditioner by a user.

In order to avoid turbulence between the sealing rib 140 and the air guide body 130, the side of the sealing rib 140 facing the air outlet is provided with an air guide surface 141, and the connection part of the air guide surface 141 and the reinforcing layer is in arc transition connection.

In this embodiment, the air guiding surface 141 is a smooth curved surface, and the air guiding surface 141 guides the air flow blown between the air guiding plate 100 and the face frame 700 to the windward side of the air guiding body 130, so as to prevent the air flow from forming a worm wheel or turbulence at the connection between the sealing rib 140 and the air guiding body 130. Thereby effectively reducing the loss of wind energy and being beneficial to reducing the loss of wind energy.

In order to further reduce the loss of wind energy, the wind guide surface 141 is provided with a wind guide member 150. The flow guide part 150 is provided with a windward side 151, a turbulent side 152 and a leeward side 153 which are connected in sequence; the windward side 151 and the spoiler 152 are in arc transition, and the spoiler 152 and the leeward side 153 are in arc transition.

In this embodiment, the flow guide member 150 extends along the length direction of the sealing rib 140, and the length and the number of the flow guide member 150 can be set according to actual conditions, for example, a plurality of shorter flow guide members 150 can be set, the plurality of flow guide members 150 are arranged at intervals along the length direction of the sealing rib 140, and of course, the length of the flow guide member 150 can also be set to be the same as the length of the sealing rib 140. The cross-sectional shape of the flow guiding element 150 may be various, such as triangular, square, rectangular, etc., in this embodiment, the cross-sectional shape of the flow guiding element 150 is similar to a normal distribution curve, that is, the flow guiding element 150 has a windward side 151, a spoiler side 152 and a leeward side 153 which are arranged in sequence, and all three sides are transited through an arc. Through the arrangement of the flow guide member 150, the air flow blown between the sealing rib 140 and the air guide body 130 flows under the action of the flow guide member 150, so that the air flow is prevented from generating turbulence or turbulence. Thereby effectively reducing the loss of wind energy and being beneficial to reducing the loss of wind energy.

The wind guide body 130 comprises a base layer 500, a heat insulation layer 400 and a reinforcing layer 300 which are sequentially stacked;

The windward side 110 of the wind guide body 130 guides the airflow flowing out from the wind outlet, and the reinforcing layer 300 is located on the windward side 110, so that the temperature of the reinforcing layer 300 is close to the temperature of the air after heat exchange of the air conditioner. The leeward side 120 faces away from the air outlet, and the temperature of the base layer 500 is equal to the ambient temperature. When there is a temperature difference between the reinforced layer 300 and the insulation layer 400, the reinforced layer 300 and the insulation layer 400 perform heat exchange, and because the heat transfer effect of the insulation layer 400 is poor, the heat exchange movement performed with the reinforced layer 300 is not severe, and the temperature changes of the heat-exchanged reinforced layer 300 and the reinforced layer 400 are small. Since the temperature change of the reinforcing layer 300 is small, the temperature difference between the front and back surfaces of the reinforcing layer 300 is small, and thus, condensation is not formed on the reinforcing layer 300 due to the temperature difference.

Similarly, when there is a temperature difference between the base layer 500 and the insulation layer 400, the base layer 500 and the insulation layer 400 perform heat exchange, and because the heat transfer effect of the insulation layer 400 is poor, the heat exchange movement performed with the base layer 500 is not severe, and the temperature changes of the insulation layer 400 and the base layer 500 after heat exchange are small. Since the temperature change of the base layer 500 is small, the temperature difference between the front and rear surfaces of the base layer 500 is small, and thus condensation is not formed on the base layer 500 due to the temperature difference.

The base layer 500 is an injection molding layer made of ABS plastic, and the reinforcing layer 300 is made of metal, such as stainless steel; the insulating layer 400 may be made of insulating material, such as a cotton fabric, foam, etc., or may be a hollow structure, and air itself is a good insulating material, and naturally, the vacuum structure may also be a form of the insulating layer 400.
