The embodiment of the utility model provides an aviation baffle. Fig. 1 is a schematic view of an air deflector according to an embodiment of the present invention when the movable guide plate is in a retracted state; FIG. 2 is a schematic side view of the air deflection plate of FIG. 1; FIG. 3 is a schematic view of the deflector of FIG. 1 with the movable guide plate in an extended condition; figure 4 is a schematic side view of the air deflection plate shown in figure 3.

As shown in fig. 1 to 4, the air deflection plate 50 of the present invention may generally include an air deflection plate body 51, a movable guide plate 52, and a driving device 54. The air deflector body 51 is adapted to be rotatably mounted at the outlet 12 of the air conditioner (see fig. 8), and the rotation axis thereof is the x-axis indicated in the figure. The air deflector body 51 is used for opening or closing the air outlet 12, and when the air outlet 12 is opened, the air deflector body can be controlled to rotate to different angles to change the air outlet direction of the air outlet 12, so that the air can be blown to different indoor areas. When the air deflector 50 is used for guiding air, the end B where the air flow firstly reaches is a windward end, and the end A where the air flow finally passes through is an air outlet end.

The movable guide plate 52 is movably mounted to the air guide plate body 51 to guide the direction of the air flow together therewith. The movable guide plate 52 is located in a region near the air outlet end (end a) of the air guide plate body 51.

The driving device 54 is used for driving the movable guide plate 52 to move, and specifically includes driving the movable guide plate 52 to move from a retracted state (see fig. 1 and 2) on the air deflector body 51 side toward the downstream direction of the air flow to an extended state (see fig. 3 and 4), and driving the movable guide plate 52 to move from the extended state toward the upstream direction of the air flow to return to the retracted state. In the retracted state, the air outlet end (C end) of the movable guide plate 52 may or may not extend out of the air outlet end a of the air deflector body 51. However, in the extended state, the air outlet end of the movable guide plate 52 needs to extend beyond the air outlet end (B end) of the air deflector body 51 to extend the air outlet distance of the air deflector 50. In this case, the area from the windward end B of the air guide plate body 51 to the air outlet end C of the movable guide plate 52 is used for guiding air.

The utility model discloses make aviation baffle 50's wind-guiding distance adjustable. For example, when the air conditioner is normally operated, the movable guide plate 52 may be in the retracted state, and the air guide distance of the air guide plate 50 may be minimized. When the air conditioner needs to supply air in a long distance or needs to supply air upwards or downwards more comprehensively, the movable guide plate 52 can be moved to the extending state, so that the air guiding distance of the air conditioner is increased. Of course, the air guiding distance of the air guiding plate 50 is related to the extent of extension of the movable guide plate 52, and the longer the movable guide plate 52 extends, the greater the air guiding distance of the air guiding plate 50.

Compared to the case where the movable guide plate 52 is mounted outside the air guide plate body 51, it is preferable that the movable guide plate 52 is located inside the air guide plate body 51 (when the air guide plate body 51 is at an angle to close the outlet 12, the side facing the inside of the outlet 12 is the inside, and the side facing the outside is the outside) so that the air guide plate body 51 shields the movable guide plate 52 to a certain degree, and the appearance of the air guide plate 50 is relatively more beautiful.

In some embodiments, the movable guide plate 52 can be configured to abut against the inner surface 511 of the deflector body 51 in either the retracted state or the extended state.

In a preferred embodiment, the movable guide plate 52 is mounted inside the air guide plate body 51 at a distance from the air guide plate body 51. That is, a ventilation gap is defined between the movable guide plate 52 and the inner surface 511 of the air deflector body 51 to allow the air flow to pass therethrough. Thus, when the airflow passes through the surface of the air deflector body 51, the airflow is disturbed by the movable guide plate 52, a part of the airflow flows out along the outer side of the movable guide plate 52, and a part of the airflow flows out from the spaced area between the movable guide plate 52 and the air deflector body 51, namely, the airflow is split and scattered. After being scattered by the movable guide plate 52, the airflow is not intensively blown indoors, the blowing force is weakened, the airflow becomes softer, the wind feeling is closer to natural wind, and the effect of comfortable air supply is achieved. The double-layer air guide structure of the air guide plate 50 can also avoid the condensation phenomenon at the air outlet 12 when the air conditioner operates in a refrigerating mode.

In order to improve the air supply comfort, in the prior art, when an air conditioner is used for cooling, the air deflector is expected to guide cold air to blow out vertically and upwards as much as possible. However, when the air deflector approaches the limit air guiding angle of the upward blowing, the included angle between the air deflector and the plane of the air outlet 12 is too small, that is, the opening degree is very small, the air deflector will seriously shield the air outlet 12, and the air volume becomes very small. This limits the wind guiding angle range of the wind guiding plate. Especially, when the air is guided vertically, the air guiding angle and the air volume are difficult to be considered simultaneously.

In some embodiments, as shown in fig. 1-4, the wind deflector further comprises a plurality of guide arms 513. The plurality of guide arms 513 are arranged in a direction parallel to the rotation axis (x-axis) of the air deflector body 51. Each guide arm 513 extends from the inner surface of the air deflection body 51 in the downstream direction of the air flow and gradually away from the air deflection body 51. The movable guide plate 52 is mounted to the plurality of guide arms 513 to move between the retracted state and the extended state along the extending direction of the guide arms 513. This allows the movable guide plate 52 to be at a greater angle to the air deflector body 51 when in the extended state. When the air conditioning requires the wind to be blown upward, the movable guide plate 52 functions to guide the wind upward. This eliminates the need to rotate the air deflector body 51 to an excessively vertical state (i.e., close to the state of closing the outlet 12) to avoid the air output from being greatly affected.

The straight sides of the air deflector body 51 and the movable guide plate 52 can be parallel to the rotation axis (x axis) of the air deflector body 51, and the convex sides of the two are towards the same arc-shaped plate, so that the air can be guided more vertically upwards during refrigeration. Both ends of the movable guide plate 52 are flush with both ends of the air deflector body 51 in a direction parallel to the rotational axis (x-axis) of the air deflector body 51 (i.e., the movable guide plate 52 and the air deflector body 51 are the same length).

In some embodiments, as shown in fig. 1 to 5, each guide arm 513 is provided with at least one support wheel 5131, 5132 that is capable of fixed-axis rotation (the position of the rotation axis with respect to the guide arm 513 is not changed) to support the movable guide plate 52. When the movable guide plate 52 moves, the support wheels 5131 and 5132 are driven by the movable guide plate 52 to rotate, so that the movable guide plate 52 can move more easily. The inner side of the air deflector body 51 is provided with a limit sliding chute 518, and the movable guide plate 52 is provided with a limit sliding strip 521. The limit runner 521 is disposed in the limit runner 518, and is limited to be slidable only in the lengthwise direction of the limit runner 518 (not movable in other directions), so as to limit the movable guide plate 52 to be movable only in the extending direction of the guide arm 513 (without being disengaged from the guide arm 513). Two convex strips 517 which are arranged in parallel at intervals can be installed on the inner surface of the air deflector body 51, and a spacing sliding groove 518 is formed in the space between the two convex strips 517. Each guide arm 513 preferably mounts two support wheels 5131, 5132.

As shown in fig. 5 to 7, the outer profile cross section of the limit slider 521 is preferably made to be a trapezoid whose upper base connects the surface of the movable guide plate 52 (i.e., the two side surfaces of the limit slider 521 extend from the surface of the movable guide plate 52 gradually away from each other in a direction away from the movable guide plate 52). The limiting sliding groove 518 is a trapezoidal groove with two gradually approaching side walls from the groove bottom to the opening direction (the two side walls of the limiting sliding groove 518 start from the inner surface of the air deflector body 51 and extend gradually approaching in the direction away from the air deflector body 51) to match with the outer contour shape of the limiting sliding strip 521, so as to prevent the limiting sliding strip 521 from separating from the limiting sliding groove 518 through the opening of the limiting sliding groove 518.

The number of the guide arms 513 is preferably two, and the two guide arms 513 are respectively located at both ends of the inner surface (parallel to the x-axis direction) of the air deflector body 51. With the stop runner 518 located between the two guide arms 513. This enables more uniform restraint of the movable guide plate 52, more overall spacing, and more smooth movement.

Each of the first motors 541 is used to directly or indirectly drive one of the support wheels 5131, 5132 to rotate so that the movable guide plate 52 is moved by the support wheel 5131, 5132. Preferably, two first motors 541 are provided, and each first motor 541 drives one support wheel of one guide arm 513 to rotate, so that both ends of the movable guide plate 52 are driven synchronously to move more precisely. The two first motors 541 are stepping motors that can be controlled to rotate forward and backward.

As shown in fig. 2 and 4, the driving device 54 may further include at least one reduction gear set matched with the at least one first motor 541, so as to make the rotation speed of the supporting wheel lower than that of the first motor 541, thereby avoiding the need to design the first motor 541 with too low rotation speed and increasing the cost. Each of the reduction gear sets includes a first gear 542 and a second gear 543 that mesh with each other, and a diameter of the first gear 542 is smaller than a diameter of the second gear 543. The first gear 542 is mounted to the first motor 541 to be driven thereby, and the second gear 543 is coaxially fixed thereto with the support wheel.
