[0029] The following is combined with Figures 1 to 7 This invention describes an air guide plate device. The air guide plate device includes: a cover 1, a first air guide plate 2, and a second air guide plate 3.

[0030] The cover 1 has an air duct; the first air guide plate 2 is disposed in the air duct and is rotatably disposed on the cover 1; the second air guide plate 3 is disposed downstream of the first air guide plate 2 and is rotatably disposed on the cover 1, and the surface of the second air guide plate 3 has an air outlet structure 31.

[0031] Specifically, the casing 1 serves as the supporting structure for the indoor unit, and it has a frame and a cover, with an internal air duct for air intake and exhaust. At the air outlet of the air duct, a first air guide plate 2 and a second air guide plate 3 are arranged sequentially along the air outlet direction, and the first air guide plate 2 and the second air guide plate 3 can rotate independently.

The cover 1 forms an air duct; the first air guide plate 2 is disposed in the air duct and rotatably disposed on the cover 1; the second air guide plate 3 is disposed downstream of the first air guide plate 2 and rotatably disposed on the cover 1, and an air outlet structure 31 is formed on the surface of the second air guide plate 3. The air guide plate device provided by this utility model includes a first air guide plate 2 and a second air guide plate 3 that can be rotated independently. The first air guide plate 2 mainly serves to extend the air duct and increase the maximum air delivery distance. In addition, the first air guide plate 2 can be rotated independently to guide the air outlet direction; the second air guide plate 3 can adjust the air outlet direction by rotation to achieve the function of preventing direct blowing; in addition, the air outlet structure 31 is formed on the second air guide plate 3. In the anti-direct blowing mode, the air can be blown out through the air outlet structure 31, which can reduce the problem of direct blowing on the one hand, and reduce the condensation problem caused by the exhaust air blowing towards the inner wall of the second air guide plate 3 on the other hand.

[0034] In one embodiment of this utility model, the air guide plate device further includes: a pushing mechanism, a linkage mechanism, and a fixed base 4. The pushing mechanism is located inside the housing 1; the linkage mechanism is connected to the pushing mechanism; and the fixed base 4 is fixed to the inner side of the second air guide plate 3 and hinged to the linkage mechanism. Specifically, the pushing mechanism drives the linkage mechanism to push out, the linkage mechanism drives the fixed base 4 to rotate, which in turn drives the second air guide plate 3 to rotate, thereby guiding the airflow.

[0035] In one embodiment of this utility model, the fixed base 4 has a first rotating shaft and a second rotating shaft.

Since a double-link structure is used in this embodiment, different air delivery angles can be achieved.

[0036] In one embodiment of this utility model, the ejection mechanism includes a drive unit and a guide plate 63. The drive unit is connected to the first connecting rod 51 and the second connecting rod 52; the guide plate 63 has a first guide groove 64 and a second guide groove 65. One end of the first connecting rod 51 is movably disposed in the first guide groove 64, and one end of the second connecting rod 52 is movably disposed in the second guide groove 65. In this embodiment, both the first guide groove 64 and the second guide groove 65 extend along the outer side of the cover 1. They can be grooves or curved grooves, and the specific structural form is determined according to the rotation requirements of the second air guide plate 3.

In this embodiment, two cranks 62 can be used, one crank 62 driving the first connecting rod 51 and the other crank 62 driving the second connecting rod 52. Alternatively, one crank 62 can simultaneously drive the first connecting rod 51 and the second connecting rod 52 to move synchronously. As long as the crank 62 can drive the first connecting rod 51 and the second connecting rod 52 to extend / retract, thereby driving the fixed seat 4 to rotate and achieving the angle adjustment of the second air guide plate 3, the requirements are met. The positions of the third and fourth shafts in the crank 62, as well as the dimensions of the connecting rods, the extension direction and dimensions of the first guide groove 64 and the second guide groove 65, can be determined according to the rotation center required for the rotation of the air guide plate. For example, as...
