This sweep wind baffle has adopted deformation rib 1 to come as the partial structure of sweeping the wind baffle, can change the size of the hole of crossing on the wind baffle through the width of adjusting deformation rib 1, pass the wind hole size on the wind baffle is swept through the regulation, can conveniently adjust the area of crossing of sweeping the wind baffle, realize that the air conditioner does not have the wind, breeze, apoplexy and the multistage air regulation such as blow directly, realize multiple different air-out modes, the air-out regulatory function of sweeping the wind baffle has been improved, furthest satisfies the diversified demand of different crowds to the air conditioner wind, promote the travelling comfort that the air conditioner used.
The width regulation of deformation rib can be realized through the mode of applying atmospheric pressure, hydraulic pressure or voltage, and in this embodiment, deformation rib 1 is made by electrostrictive material, can adjust the width of deformation rib 1 through the voltage at control deformation rib 1 both ends, and then realize the regulation to the area of crossing the wind on the wind baffle of sweeping.
The material of the electrostrictive material assembly includes all materials which can change in volume and size regularly under the action of voltage and can restore to the original shape when no voltage is applied, and includes but is not limited to high polymer materials, such as electroactive polymers and the like.
The supporting component comprises a supporting frame 2 and a cross bar 3 arranged in the supporting frame 2, wherein a deformation rib 1 is vertically arranged and is arranged in the cross bar 3 in a penetrating manner, and two ends of the deformation rib 1 are connected to a cross rib 4 of the supporting frame 2. Through setting up braced frame 2 and horizontal bar 3, can be regular to the deformation direction of deformation rib 1 for deformation takes place towards the deformation direction of predetermineeing for deformation rib 1, thereby conveniently adjusts the size in cross wind hole, satisfies user's air-out mode regulation needs, and regulation control is simple and convenient.
The inside conductor that is provided with of horizontal muscle 4, a plurality of deformation ribs 1 are parallelly connected through the conductor. All be provided with the conductor in two horizontal muscle 4 of braced frame 2, parallelly connected through the deformation rib 1 that makes these electrostrictive materials through the conductor, then utilize the conductor at deformation rib 1 both ends to exert voltage to electrostrictive materials through voltage control module, adjust the interval between two adjacent deformation ribs 1, and then adjust the size in wind hole.
The wind sweeping baffle further comprises a voltage control unit used for adjusting the voltage applied to the two ends of the deformation rib 1. Through setting up voltage control unit, can conveniently exert preset voltage to sweeping deformation rib 1 of wind baffle, satisfy the air volume control requirement of various different air-out modes.
And in the non-electrified state, the deformed ribs 1 are in a closed structure.
In the middle of another embodiment, the supporting component includes braced frame 2 and the vertical retort of setting in braced frame 2, and deformation rib 1 transversely sets up to wear to establish in the vertical retort, the both ends of deformation rib 1 are connected on braced frame 2's vertical retort.
