Disclosed is a refrigerator having a cabinet for forming a cooling compartment, and a duct for forming a passage of cool air. The duct is provided in an inner wall of the cooling compartment and has at least one cool air discharge port opened into the cooling compartment. The refrigerator has a pair of horizontal-dispersing blades disposed near the cool air discharge port in the duct, a rotational shaft connected with the horizontal-dispersing blades and extended along a vertical axis, and a motor for driving the rotational shaft. The cool air is uniformly dispersed in the cooling compartment.

Refrigerator having cool air dispersing blades

Disclosed is a refrigerator having a cool air dispersing device capable of dispersing cool air horizontally and vertically. In a duct of a fresh food compartment are installed a horizontal dispersing blade for dispersing the cool air flowing thereinto horizontally and a vertical dispersing blade for dispersing it vertically. The horizontal dispersing blade is rotated by a motor, and the rotation of the motor is transmitted to the vertical dispersing blade as an elevational/de-elevational movement. Thus the vertical dispersing blade is rotated while the horizontal dispersing blade is rotated, whereby the cool air discharged into the compartment is dispersed horizontally and vertically. Therefore, the temperature in the compartment is maintained uniform.

Refrigerator having horizontal and vertical dispersing blades

Disclosed is a refrigerator having cool air dispersing blades. The blades are rotatably disposed near cool air discharge ports in a duct. The discharge direction of the cool air is determined by angular positions of the blades. The blades are driven by a motor capable of controlling an angular position thereof. A microprocessor controls the motor so that the angular position of the blades is successively changed with a predetermined time interval. Then the temperature of the compartment is maintained uniform effectively.

Refrigerator having cool air dispersing blades of which angular position

Disclosed is a refrigerator having a device for dispersing cool air in a cooling compartment. A duct having cool air discharge ports is formed in an inner wall of the compartment. In the duct are installed a horizontal-dispersing blade disposed along a vertical rotational shaft, and a vertical-dispersing blade capable of rotating with respect to a horizontal axis. A worm gear in installed on the shaft, and a worm wheel engaged with the worm gear is installed on the vertical-dispersing blade. As the shaft is rotated by a motor, the blades rotate. Thus, the cool air is uniformly dispersed in the compartment, and the temperature in the compartment is maintained uniform. The angular position of the blades are controlled independently of each other substantially, so concentrative cooling can be performed easily.
