REFRIGERATOR AIR DUCT STRUCTURE HAVING TERNARY VECTOR AIR OUTLET

摘要

A refrigerator air duct structure having a ternary vector air outlet comprises an air duct cover plate (7) connected to an air duct. The air duct cover plate (7) is provided with a universal joint steering mechanism capable of swaying along several directions. The universal joint steering mechanism is provided with an air outlet. The universal joint steering mechanism comprises a first support (1), a second support (2), a first stepper motor (3), and a second stepper motor (4). The first support (1) is an annular support. The second support (2) is in the structure of a spherical surface. In the air duct structure, vector control is implemented on the air outlet, so that a small number of air outlets can achieve even distribution of air flow in the refrigerator and even temperature in the refrigerator, and therefore foods stored in the refrigerator can receive even cold energy, the volume of the air duct is reduced, and the volume capable of being used by a user is increased.
