The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is described in detail.
Extremely shown in Figure 8 as Fig. 1, the invention discloses a kind of refrigerator air duct structure with ternary vector air port, comprise the air channel cover plate 7 and the universal joint steering mechanism that are connected the air channel, universal joint steering mechanism can be along several direction swings, and universal joint steering mechanism is provided with the air port.
In the present embodiment, universal joint steering mechanism can be simultaneously towards about four direction swing up and down.
Concrete, universal joint steering mechanism comprises first support 1, second support 2, first stepper motor 3 and second stepper motor 4, described first support 1 is annular support, second support 2 is sphere shape structure, the overall diameter of the inner ring diameter of first support 1 and second support 2 matches, the rotating shaft of upper end for being used for blocking air channel cover plate 7 and first support 1 being rotated, the lower end is the rotating shaft of the assembling that matches with the 3 set rotating shafts of first stepper motor, second support, 2 one ends are provided with the little rotating shaft with 1 assembling of first support, second stepper motor 4 and 2 assemblings of second support, the rotating shaft of second stepper motor 4 just with the little rotating shaft of second support 2 at same axis, described air port is located at the centre position in second support 2, for air quantity can be sprayed along set direction, the place arranges kuppe 5 in the air port, be arranged in hemispheric second support 2, produce turbulent flow when avoiding cold wind to come out from the air port.
In the present embodiment, whole ducting part is connected in the air channel by air channel cover plate 7.
Cover plate 7 inside in air channel are provided with reinforcement 8, on the reinforcement 8 draw-in groove are arranged, and the upper end of first support 1 is a rotating shaft, the draw-in groove of the reinforcement 8 that the rotating shaft external diameter snaps in; The lower end of first support 1 is similarly a rotating shaft, and inside leaves a semicircle orifice, the fixing assembling that matches with the semicircle rotating shaft of first stepper motor 3, and other first stepper motor 3 is by screw 11 and air channel cover plate 7 mounts.3 rotations of such first stepper motor, then the one 3 support 1 is with regard to left-right rotation.Referring to Fig. 4 and Fig. 5 is respectively air port of the present invention parts left and to the right the action schematic diagram.
