The end of the rectifying plate 4213 is connected with the end of the first grating plate 426, a bending included angle is formed between the second plane and the first plane, the opening of the bending included angle faces the second air deflector, the bending included angle can be an obtuse angle, and the bending included angle is larger than the twentieth included angle a2, so that the flowing direction of air flowing through the first grating plate 426 is changed to be larger, and the air outlet range of air flowing into a room is larger.

The second plane can be parallel to the vertical plane in the front-back direction of the casing, so that the air outlet direction of the air flowing into the room can be better guided to the front side of the indoor unit of the vertical air conditioner, and the disturbance of the indoor air and the heat exchange between the air outlet of the air conditioner and the indoor air are facilitated.

In some embodiments, the rectifying plates 4213 are integrally formed with the first grating plates 426, so as to reduce the installation of components and improve the assembly efficiency of the air conditioner.

In some embodiments, the rectifying plate 4213 is rotatably connected to the first grating plate 426, the rectifying plate 4213 is connected to a rectifying plate 4213 motor in the height direction of the casing, a driving shaft of the rectifying plate 4213 motor is connected to the rectifying plate 4213, and the rectifying plate 4213 motor is used for driving the rectifying plate 4213 to rotate. Therefore, the angle between the plane of the rectifying plate 4213 and the plane of the first grating plate 426 can be changed by adjusting the rotation angle of the rectifying plate 4213, so that the rectifying plate 4213 can flexibly adjust the air guiding range of the heat exchange air flowing through the first grating plate 426 to meet different use requirements of users.

The rectifying plates 4213 include a windward side and a leeward side, and sides of the rectifying plates 4213 for changing the flow direction of the air flowing through the first grating plates 426 are defined as windward sides, and sides opposite to the windward sides are defined as leeward sides.

The included angle between the second plane and the first plane of the first grid plate 426 connected to the corresponding rectifying plate 4213 is defined as a twenty-first included angle a3, the opening of the twenty-first included angle a3 faces the first air deflector, and the twenty-first included angle a3 is disposed forward and is located on the leeward side of the plane where the rectifying plate 4213 is located. The twenty-first included angle a3 has an arbitrary value of 60-70 degrees, which is beneficial to increasing the air outlet range and preventing the air outlet directions from being mutually collided due to overlarge change of the rectifying plates 4213 on the air guiding directions, thereby avoiding influencing the air outlet quantity.

The air outlet frame 42 further comprises a second grating plate 427, and the second grating plate 427 is connected with the first grating plate 426 and is staggered, so that the connection strength of the first grating plate 426 is improved, and the first grating plate 426 is prevented from shaking during air outlet.

The second grating plate comprises a third profile surface, the third profile surface is arranged on one of two opposite sides of the second grating plate, and the third profile surface is arranged in parallel with the horizontal plane, so that the wind shielding effect of the second grating plate 427 on the air after heat exchange is reduced, and the air outlet quantity is improved.

The air outlet frame 42 includes a first side portion and a second side portion that are disposed opposite to each other, the front volute tongue 251 is connected to the first side portion of the air outlet frame, the rear volute tongue is connected to the second side portion of the air outlet frame, and the first plane guides the air flowing out of the volute tongue air channel to the first side of the air outlet frame.

The front volute tongue 251 comprises a volute tongue wind-guiding surface for guiding the flow direction of air after heat exchange, and the volute tongue wind-guiding surface comprises a volute tongue contour line parallel to the horizontal plane, wherein the volute tongue contour line is parallel to the first plane.

In some embodiments, the angle between the straight line of the volute tongue contour line and the vertical surface in the front-back direction of the casing is defined as a twenty-second angle a4, and the value of the twenty-second angle a4 is any value between 60 ° and 70 °. The twenty-second included angle a4 is set to be any value between 60 degrees and 70 degrees, so that the air outlet quantity in the volute tongue air channel can be improved, and the air outlet effect is improved.

The first plane is parallel to the straight line where the contour line of the volute tongue is located, so that the resistance of the first grating plate to air flowing out of the volute tongue air channel is reduced, the air outlet quantity flowing out of the heat exchange air outlet is further enabled to be larger, and the air outlet effect is better.
