  • the link member 61 has a guiding piece 69 protruding toward the duct plate 9.
  • the guiding piece 69 is accommodated in the raising and lowering guiding part 49 formed on the inner wall of the duct plate 9.
  • the raising and lowering guiding part 49 accommodates the guiding piece 69 so as to guide it up and down and prevent the link member 61 from rotating.
  • the cool air dispersing device is controlled by a microprocessor 70.
  • the microprocessor 70 receives signals from the first and second temperature sensors 9a, 9b and calculates the temperture distribution on the basis of the sensed temperatures.
  • the microprocessor 70 controls the driving motor 35 according to the calculated temperature distribution.
  • the microprocessor 70 also controls the compressor 11 and the fans 13a, 13b to control the generation and supply of the cool air.
  • the raising and lowering cam 63 rotates with the rotational shaft 31, and the link member 61 is raised and lowered by the operation part 67 which is engaged with the cam groove 65 of the raising and lowering cam 63.
  • the up and down movement of the link member 61 causes pivoting of the vertically-dispersing blades 57 relatively to the horizontal rotational shaft 53 through the hinge assembly part 62 and the hinge part 55 of the vertically-dispersing blades 57.
  • the raising and lowering of the link member 61 is guided vertically by the guiding piece 69 and the raising and lowering guiding part 49. Therefore, the link member 61 does not rotate but reciprocates in the vertical direction while the raising and lowering cam 63 rotates.
  • the microprocessor 70 checks (step S1) whether the fresh food compartment fan 13b is running or not. If the fresh food compartment fan 13b is running, the microprocessor 70 senses the distribution of the temperature in the fresh food compartment 3 in order to perform the concentrative cooling according to the present invention.
  • the microprocessor 70 senses (step S2) the temperature in the fresh food compartment 3 using the first and second temperature sensors 9a, 9b, and calculates (step S3) the difference between the temperatures at the sensed positions.
  • the microprocessor 70 calculates the degree of the deviation of the temperatures on the basis of whether the temperature difference is over a predetermined value X or not.
  • the predetermined value X is determined in consideration of the kind, size, and cooling capacity of the refrigerator, and is preferably determined to be from 2 to 3 degrees centigrade.
  • step S4 the microprocessor 70 rotates (step S4) the rotational shaft 31 continuously in a constant speed. Therefore, the cool air is dispersed uniformly by the rotating horizontally-dispersing blades 33.
  • the vertically-dispersing device 40 operates together while the horizontally-dispersing device 30 is operating, so cool air is dispersed uniformly in horizontal direction as well as vertical direction. Furthermore, since the horizontally-dispersing blades 33 are planar, vortices in the cool air flow are not generated by the horizontally-dispersing blades 33.
  • the microprocessor 70 compares (step S5) the temperature of the first area sensed by the first temperature sensor 9a with the temperature of the second area sensed by the second temperature sensor 9b, and stops the driving motor 35 so that the horizontally-dispersing blades 33 are directed to the area of higher temperature.
  • the concentrated cooling of a high temperature area is realized.
  • step S6 controls the driving motor 35 so that the horizontally-dispersing blades 33 are rotated right as shown in Figure 10.
  • the vertically-dispersing blades 57 are rotated upward as shown in Figure 13. Then the cool air is discharged to be concentrated on the first area.
  • step S7 controls the driving motor 35 so that the horizontally-dispersing blades 33 are rotated left as shown in Figure 9.
  • the vertically-dispersing blades 57 are rotated downward as shown in Figure 12.
  • cool air is discharged so as to be concentrated on the second area. Since the cool air is discharged to the high temperature area in a concentrative manner, the temperature in the fresh food compartment 3 is maintained uniform.
  • horizontally-dispersing blades 33 are disposed in correspondence with respective cool air discharge ports 16.
  • a single long blade, extending past all of the cool air discharge ports 16, could be used.
  • the vertically-dispersing blades 57 operate together with the horizontally-dispersing blades 33. However, they could be driven independently. That is, if an additional driving motor controlled by the microprocessor 70 is provided, and the link member 61 is operated not by the raising and lowering cam 63 but by the additional driving motor, it is possible to control independently the angular stop positions of the vertically-dispersing blades 57. Then, the concentrative cooling on a specific area or the dispersing of the cool air by continuous reciprocation can be performed in the vertical direction as well. In this case, it is preferable that a plurality of temperature sensors are provided at a plurality of respective positions.
  • the highest temperature area can be detected from among a plurality of areas.
  • the vertically-dispersing blades 57 and the horizontally-dispersing blades 33 which are controlled independently of each other, can then direct cool air to the detected high temperature area.
