  • FIGs 8 and 9 show the discharge states of cool air guided by the cool air dispersing device 30 according to the first embodiment of the present invention. While the cam 51 is being rotated by the driving motor 59, the operation bar 69 slides reciprocally in horizontal direction along the guide grooves 65 and 67. The sliding of the operation bar 69 is converted to the rotational movement of the horizontal dispersing blade 43 by the operation groove 49. Therefore, while the cam 51 is rotating continuously, the horizontal dispersing blade 43 reciprocates between the states that it is rotated left as shown in Figure 8 and rotated right as shown in Figure 9.
  • the horizontal dispersing blade 43 When the horizontal dispersing blade 43 is rotated left as shown in Figure 8, the cool air in the supply duct 15 is discharged to the left area in the fresh food compartment 3. Similarly, when the horizontal dispersing blade 43 is rotated right as shown in Figure 9, the cool air in the supply duct 15 is discharged to the right area in the fresh food compartment 3. Therefore, while the horizontal dispersing blade 43 is rotating reciprocally within a predetermined angle, the cool air is dispersed horizontally, whereby the uniform distribution of cool air in the fresh food compartment 3 is realized. Furthermore, since the horizontal dispersing blade 43 has a shape of a planar plate, there occurs no vortex of cool air during the cool air dispersing operation of the horizontal dispersing blade 43.
  • the concentrative cooling can be realized by stopping the driving motor 59 when the horizontal dispersing blade 43 is directed to the corresponding area.
  • a control part (not shown) drives the driving motor 59 on the basis of the temperature in the fresh food compartment 3 sensed by the temperature sensors 9a and 9b.
  • the control part stops the cam 51 so that the cool air is guided toward the specific area of which temperature has risen. Therefore, the specific area is cooled in a concentrative manner, and the uniform distribution of cool air in the fresh food compartment 3 can be achieved in a short period of time.

  • the operation of the cool air dispersing device 40 according to the present embodiment is the same with that of the above-described first embodiment. That is, as the driving motor 59 rotates the cam 51, the horizontal dispersing blades 43 rotate reciprocally within a predetermined angle. Thus, the cool air is dispersed horizontally. According to the present embodiment, since the cool air is discharged through the discharge ports 16a and 16b which respectively correspond to the upper and lower areas in the fresh food compartment 3, the cool air can be supplied respectively to the stratified areas in the fresh food compartment 3.
  • a pair of discharge ports 16a and 16b and a pair of horizontal dispersing blades 43 are provided, however, the number of them can be changed in consideration of the number of the stratified areas in the fresh food compartment 3 which are partitioned vertically from each other.

  • the operating protrusion 69a of the operation bar 69 is inserted into the upper slot 81, and the elevating/de-elevating protrusion 83 of the link member 81 is inserted into the lower slot 82.
  • the elevation/de-elevation member 86 pivots reciprocally about the pivoting shaft 99 in vertical direction, whereby the link member 81 is elevated/de-elevated reciprocally. Therefore, the vertical dispersing blades 71 reciprocally rotate within a predetermined angle, and the cool air in the supply duct 15 is dispersed into the fresh food compartment 3.
  • the horizontal dispersing blade 43 is rotated reciprocally in horizontal direction by the transmission part 61, and simultaneously the vertical dispersing blades 71 are rotated reciprocally in vertical direction by the elevation/de-elevation guide part 95, the elevation/de-elevation member 86, and the link member 81. Accordingly, the cool air is dispersed horizontally and vertically.
  • Figures 17 and 18 show a cool air dispersing device 70 according to the fifth embodiment of the present invention.
  • the construction of the horizontal dispersing blades 43a and 43b, the rotational shafts 45a and 45b, the driving motor 59, the cam 51, and the transmission parts 61a and 61b is the same as that of the above-described third embodiment. That is, a pair of horizontal dispersing blades 43a and 43b are installed respectively on a pair of rotational shafts 45a and 45b which is capable of rotating independently of each other, and they correspond respectively to a pair of discharge ports 16a and 16b. Furthermore, a pair of transmission parts 61a and 61b for respectively driving the pair of horizontal dispersing blades 43a and 43b are provided.
  • the construction of the vertical dispersing blades 71, the link member 81, the elevation/de-elevation member 86, and the elevation/de-elevation guide part 95 is the same as that of the above-described fifth embodiment. Accordingly, while the cam 51 is rotated by the driving motor 59, the horizontal dispersing blades 43a and 43b are rotated reciprocally in horizontal direction by the transmission parts 61a and 61b within a predetermined angle, and simultaneously the vertical dispersing blades 71 are rotated reciprocally in vertical direction by the elevation/de-elevation guide part 95, the elevation/de-elevation member 86, and the link member 81 within a predetermined angle. Therefore, the cool air is dispersed horizontally and vertically. Further, as described in the third embodiment, the horizontal dispersing blades 43a and 43b rotate oppositely to each other.
  • Figures 19 through 22 show a cool air dispersing device 80 according to the sixth embodiment of the present invention.
  • the rotational shaft 45 disposed vertically is installed in the supply duct 15, and the horizontal dispersing blade 43 is fixed to the rotational shaft 45.
  • a hinge protrusion 45d is formed on the upper part of the horizontal dispersing blade 43.
  • the hinge protrusion 45d has a predetermined angle with respect to the plane of the horizontal dispersing blade 43.
  • On the hinge protrusion 45d is formed a hinge pin 45e protruding downward so as to be parallel with the rotational shaft 45.
  • the hinge pin 45e interacts with an operation bar 115 which will be described later.
  • the construction of the driving motor 109 and the cam 101 is similar to that of the first embodiment. That is, the cam 101 has a cam body 103 and a cam groove 105, and a cam shaft 106 is installed on the cam body 103. However, in the present embodiment, the direction of the cam 101 is different from that of the first embodiment. In other words, the cam 101 is disposed horizontally as that of the first embodiment, but it is orthogonal to the cam 51 of the first embodiment.
  • the driving motor 109 is fixed by a motor bracket 110 attached to the rear surface of the duct plate 27.
  • One end of the cam shaft 106 is assembled with the driving shaft of the driving motor 109, and the other end thereof is inserted into a rear wall provided in the rear of the duct plate 27. Accordingly, the cam 101 is rotatably supported.
  • a guide member 117 is fixed on the rear wall 29, which is parallel with the cam shaft 106.
  • the guide member 117 has a guide groove (not shown) formed along the longitudinal direction thereof, and the guide bar 115 passes through the guide member 117 via the guide groove.
  • a pair of guide plates 116 are provided at the middle part of the operation bar 115.
  • the guide plates 116 are disposed at both sides of the guide member 117 so that they are contacted therewith.
  • the guide plates 116 support the operation bar 115 so that the operation bar 115 is maintained orthogonal to the guide member 117, whereby the operation bar 115 is capable of sliding along the guide groove of the guide member 117.
  • One end of the operation bar 115 is inserted into the cam groove 105, and the other end thereof is formed with a slot 111 for accommodating the hinge pin 45e. Therefore, when the operation bar 115 moves along the longitudinal direction of the guide member 117, the hinge pin 45e moves along the slot 111, whereby the horizontal dispersing blade 43 is rotated as shown in Figures 21 and 22.
  • the operation bar 115 is reciprocated by the cam 101, and thereby the horizontal dispersing blade 43 rotates reciprocally within a predetermined angle.
  • the cool air is dispersed horizontally.
  • a stable cool air flow and a uniform distribution of cool air in vertical and horizontal directions can be achieved without the vortex of cool air about the cool air discharge ports.
