The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is carried out detailed description.
Extremely shown in Figure 8 like 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 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, the four direction swing up and down about court simultaneously of universal joint steering mechanism.
Concrete, universal joint steering mechanism comprises first support 1, second support 2, first stepper motor 3 and second stepper motor 4, and said first support 1 is an annular support; Second support 2 is a sphere shape structure; The overall diameter of the inner ring diameter of first support 1 and second support 2 matches, and the upper end is to be used to the rotating shaft blocking air channel cover plate 7 and first support 1 can be rotated, and 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 the assembling of second support 2, the rotating shaft of second stepper motor 4 just with the little rotating shaft of second support 2 at same axis, said air port is located at the interior centre position of second support 2; For air quantity can be sprayed along set direction; The place is provided with kuppe 5 in the air port, is arranged in hemispheric second support 2, avoids cold wind when come out in the air port, to produce turbulent flow.
