The air deflector 1 is generally disposed at the air outlet 6 of the air conditioner, and when applied to a wall-mounted air conditioner, it is generally rotatably disposed at the air outlet of the air conditioner, and is generally in the shape of an arc long plate. The wind flowing out from the wind outlet 6 can flow along the wind deflector 1 towards the surface of the wind outlet 6, and the function of guiding the wind direction is achieved. Generally, in the air outlet direction, one end of the air deflector 1 used for being connected to the air conditioner shell is a connecting end, the other free end is an air outlet end, and the air flow flows to the direction far away from the air deflector 1 after passing through the air outlet end of the air deflector 1 and is discharged to the indoor.
The condensation-preventing structure of this embodiment, set up drainage device 2 in the air-out end position department of above-mentioned aviation baffle 1, drainage wind channel 100 that drainage device 2 and aviation baffle 1 cooperation formed can guide cold wind to pass through its inside and blow to aviation baffle 1 and deviate from 6 one sides of air outlet and air conditioner drain pan 7, refer to shown in fig. 3, along aviation baffle 1 towards in the wind partly situation entering drainage wind channel 100 of 6 one side of air outlet flows, blow the near hot-air in above-mentioned position after drainage wind channel 100 flows out, form one deck "cold air wall" simultaneously in drainage wind channel 100, prevent that hot-air from attaching to form the condensation on aviation baffle 1 deviates from 6 one side of air outlet and air conditioner drain pan 7, it is effectual to prevent the condensation.
As an alternative embodiment, referring to fig. 2 and 3, at least a part of the cover of the flow guiding device 2 is disposed outside the air outlet end of the air deflector 1, and the flow guiding duct 100 is formed between the inner wall of the flow guiding device 2 and the surface of the air deflector 1.
The air deflector 1 in the embodiment is an arc-shaped plate protruding towards the direction back to the air outlet 6 as a whole, and one surface of the air deflector 1 facing the air outlet 6 in the prior art is a flow guide surface for guiding air; in this embodiment, when at least a portion of the drainage device 2 is covered outside the air outlet end of the air deflector 1, a drainage air duct 100 is formed between the inner wall of the drainage device 2 and the concave surface of the air outlet end of the air deflector 1 (i.e., the surface of the air deflector 1 facing the air outlet 6, i.e., the upper surface of the air deflector 1 in fig. 2 and 3) and the convex surface of the air outlet end of the air deflector 1 (i.e., the surface of the air deflector 1 facing away from the air outlet 6, i.e., the lower surface of the air deflector 1 in fig. 2 and 3). Referring to fig. 2 and 3, air exhausted from the air outlet 6 is guided by the concave surface of the air deflector 1, a part of the air enters the air guide duct 100 to flow, and is reversed to the end edge position of the air outlet end of the air deflector 1, and is guided by the inner wall of the air guide device 2 and the convex surface of the air outlet end of the air deflector 1 to blow the convex surface part of the air deflector 1 outside the air guide device 2 and the position of the air conditioner bottom shell 7, so that hot air nearby is blown away. The other part of air flows and diffuses continuously along the concave surface of the air deflector 1 and the outer surface of the drainage device 2 in sequence in the direction far away from the air deflector 1.
Considering that the boundary layer separation phenomenon occurs when the air flow passes through the concave surface of the air outlet end of the air deflector 1, the drainage device 2 can play a drainage effect and simultaneously prevent noise from deteriorating; as an optional implementation mode, at the air outlet end of the air deflector, the drainage device covers 1/8-1/2 parts of one surface of the air deflector, which faces the air outlet, and covers 1/8-1/2 parts of one surface of the air deflector, which faces away from the air outlet; the drainage device 2 covers the part of the air deflector 1 within the above range, and can play a good drainage role and prevent noise deterioration. Preferably, as shown in fig. 2 and 3, at the air outlet end of the air deflector 1, when the drainage device 2 covers the 1/4 portion of the side of the air deflector 1 facing the air outlet 6 and covers the 1/4 portion of the side of the air deflector 1 facing away from the air outlet 6, the drainage effect and the effect of preventing the worsening noise are better.

Therefore, through theoretical analysis, at the air outlet end of the air deflector 1, when the part of the drainage device 2 covering the concave surface of the air deflector 1 occupies 1/4 of the whole concave surface, and the part of the drainage device 2 covering the convex surface of the air deflector 1 occupies 1/4 of the whole convex surface, the airflow flows along the surface of the air deflector 1, and the air deflector can play a role in drainage, reduce impact and reduce noise deterioration.
In order to reduce the influence of the drainage device 2 on the air supply effect, the air supply distance of the air deflector 1 is considered; as an alternative embodiment, referring to fig. 3, the inner diameter of the air guiding duct 100 decreases from the air inlet to the air outlet, in other words, the distance between the inner wall of the air guiding device 2 and the surface of the air deflector 1 decreases along the direction of the air flow in the air guiding duct 100; preferably, the inner diameter of the air guide duct 100 decreases gradually from the air inlet to the air outlet thereof.

The shape of the cover body 21 is matched with the shape of the air outlet end of the air deflector 1, and preferably, the position of the cover body 21 corresponding to the end edge of the air outlet end of the air deflector 1 is arc-shaped so as to enable the air flow to be stably reversed.
As an alternative embodiment, as shown in fig. 1 to fig. 3, the cover 21 has an open portion 211 (as shown in fig. 1), the open portion 211 (as shown in fig. 1) of the cover 21 and a surface of the air deflector 1 facing the air outlet 6 (a concave surface of the air deflector 1) form an air inlet of the air guiding duct 100, and a surface of the air deflector 1 facing away from the air outlet 6 (a convex surface of the air deflector 1) form the air outlet 6 of the air guiding duct 100.
The cover body 21 only includes the opening portion 211, so that the air flow is guided by the concave surface of the air deflector 1 and then enters the air guide duct 100 from the air inlet, and flows out of the air outlet 6 and then is blown to the part of the convex surface of the air deflector 1 outside the cover body 21 and the air conditioner bottom case 7, thereby reducing the accumulation of hot air near the position and preventing the generation of condensation.
As an optional implementation manner, in the present embodiment, the drainage device 2 is rotatably disposed, and an air duct closed state in which the drainage device 2 is tightly attached to the concave surface of the air deflector 1 is formed between the drainage device 2 and the air deflector 1, as shown in fig. 2; and the air duct opening state of the gap fit between the drainage device 2 and the concave surface of the air deflector 1 is shown in figure 3.
The drainage device 2 is rotatably arranged at the air outlet end of the air deflector 1 so as to realize the air duct closing state and the air duct opening state. When being difficult to produce the condensation on 1 convex surface of aviation baffle and the air conditioner drain pan 7, rotate through drainage device 2 and hug closely with 1 concave surface of aviation baffle to drainage device 2, close drainage wind channel 100, the air current no longer gets into drainage wind channel 100, prevents that drainage device 2 from still opening the influence air supply ability.
As an alternative embodiment, referring to fig. 2 and 3, the flow guiding device 2 further includes a shaft 22, and the shaft 22 is rotatably disposed on the air guiding plate 1 to drive the whole flow guiding device 2 to rotate to form an air duct closed state and an air duct open state.

The shaft 22 may be adapted to rotate by itself by being connected to a drive device. The driving mode of the driving device for driving the shaft 22 to rotate is a conventional setting in the art, and is not shown here, for example, the shaft 22 can be driven by a motor, and the shaft 22 can be connected with an output shaft of the motor through a connecting rod, so that the motor can be conveniently arranged outside the drainage device 2 without occupying the internal space of the drainage device, and further description is omitted here, and a person skilled in the art can select the driving mode according to actual conditions.
As an alternative embodiment, the drainage device 2 further comprises: the above-mentioned driving device, which is drivingly connected to the shaft 22 and drives the shaft 22 to rotate (e.g. the motor drives the shaft 22 to rotate through the connecting rod); the temperature detection device 4 is positioned in the air deflector 1 and is used for detecting the temperature of one surface of the air deflector 1, which is far away from the air outlet 6; and the controller 5 is positioned in the air deflector 1, is connected with the driving equipment and the temperature detection device 4, and is used for receiving the temperature signal of the temperature detection device 4 and controlling the driving equipment to operate according to the received temperature signal.

Preferably, the temperature detection device 4 includes a first temperature sensor for detecting the temperature of the convex surface of the air deflector 1, and a second temperature sensor for detecting the temperature of the convex surface of the air deflector 1 and the ambient temperature of the bottom shell 7 of the air conditioner, and both the first temperature sensor and the second temperature sensor are connected with the controller 5.
It should be noted that the number of the temperature detecting devices 4 may be one or more to facilitate the detection of the temperature at or near the convex surface of the air deflector 1. The controller 5 may receive the data output by the temperature sensing device 4 and compare the temperature data output by the temperature sensing device 4 to the dew point temperature of the environment. And can control the rotation of the shaft 22 of the flow guide device 2 (by controlling the operation state of the driving device to control the rotation of the shaft 22) to realize the opening and closing state of the flow guide duct 100.
The embodiment of the utility model provides an in, open the refrigeration operating mode, the cold wind that the machine blown out in the wall-hanging air conditioning realizes directional air supply through aviation baffle 1.
