It is supported in the form of leaning between the two. That is, in the stand rack 50 of this embodiment, the support area | region which can be supported in the form which leaned the strip-shaped cool storage agent B in the two area | region of this side and the back | inner side is comprised.

Then, the effect | action of this embodiment is demonstrated.
In the freezing chamber 12, the hanger rack 40 is mounted in three stages on the upper side, and the stand rack 50 is mounted in two stages below.
As shown in FIG. 15, the hanger rack 40 has hooked portions 43 provided at the left and right ends of the back edge placed on a shelf receiver 32 attached to the left and right shelf posts 30 of the back wall 12A. The left and right corners of the front edge of the main body frame 51 are placed on the shelf receivers 32 attached to the shelf columns 30 of the left and right side walls 12B. As a result, the hanger rack 40 is positioned and mounted so that it cannot move in the front-rear and left-right directions. The hanger rack 40 is mounted in a state where the intervals in the vertical direction are reduced as much as possible over three stages.

At this time, as shown in FIG. 17, in the hanger rack 40 arranged vertically, the front frame 47 of the upper hanger rack 40 is positioned above the front end portion of the horizontal frame 46 in the support frame 45 of the lower hanger rack 40. A space S that spreads toward the front side is formed between the inclined portion 47B and the inclined portion 47B.
In addition, a predetermined space (about the width of the shelf column 30) is secured between the front frame 47 (the hanging portion 47A) of the support frame 45 of the hanger rack 40 and the back surface of the heat insulating door 15 when the door is closed. In addition, a space comparable to the front side is secured between the rear frame 48 of the support frame 45 and the rear wall 12A.

On the other hand, in the upper stand rack 50 of the two stand racks 50, as shown in FIG. 16, the hooked portions 53 provided at the left and right end portions of the rear edge are the left and right shelf columns 30 of the rear wall 12A. The corner where the front receiving frame 62 and the left and right side edges of the main body frame 51 intersect is placed on the left and right side walls. The upper stand rack 50 is placed on the shelf receiver 32 attached to the shelf column 30 of 12B and is latched by the latching piece 35, so that the upper stand rack 50 is positioned so as to be immovable in the front-rear and left-right directions.
At this time, a space equivalent to the hanger rack 40 side is ensured between the front frame 57 of the support frame 55 of the stand rack 50 and the back surface of the heat insulating door 15 when the door is closed. A similar space is also secured between the connecting frame 59 and the back wall 12A.

  The lower stand rack 50 is placed directly on the bottom surface of the freezing chamber 12. As shown in FIG. 1, the bottom surface of the freezing chamber 12 is formed with a concave surface 12C having a downward slope toward the front side, and the front edge of the main body frame 51 in the stand rack 50 is in front of the concave surface 12C. The stand rack 50 is restricted from coming out to the near side by being fitted and locked inside the edge.

Next, the mat-shaped regenerator A is supported on the hanger rack 40, and the strip-shaped regenerator B is supported on the stand rack 50.
After the mat-shaped regenerator A is folded in two downwards, the bent portion is hung on the front end of the horizontal frame 46 of the corresponding support frame 45 in the hanger rack 40 as shown by the arrow in FIG. When pushed in along the frame 46, the pushing is stopped when it hits the regulation frame 49. As a result, the mat-shaped cold storage agent A folded in half is supported in a suspended form in the region on the back side of the support frame 45.
When supporting the mat-shaped cold storage agent A in the region on the front side of the support frame 45, similarly fold it in the downward direction, hang the folded portion on the horizontal frame 46 in the corresponding support frame 45, and place the rear edge side in the back. The front edge of the mat-shaped regenerator A supported in the side region is overlapped with the front edge of the support frame 45 so that the front edge is aligned with the front frame 47 (the hanging portion 47A). It is supported in the form of being suspended in the area on the near side (see the upper part of the figure).

  Here, especially in the second and third hanger racks 40 from the top, if the vertical distance is narrow, it can be said that it is difficult to hang the mat-shaped cold storage agent A on the support frame 45. In the embodiment, the mat-shaped regenerator A in the second-stage and third-stage hanger racks 40 has a shape in which the mouth is opened so as to spread toward the front side. It is easy to insert A and to hang it on the horizontal frame 46 of the support frame 45.

When the mat-shaped regenerator A is supported in a manner suspended on the back side and the front side of the hanger rack 40 at each stage in the manner described above, after the mat-type regenerator A supported on the back side, The edge is restricted from being pushed further into the back side by hitting the restriction frame 49, in other words, between the rear edge of the mat-like cold storage agent A on the back side and the back wall 12 </ b> A, a cold air passage 65 with a predetermined interval. Is secured.
On the other hand, the mat-shaped regenerator A supported on the front side is supported by being suspended in a form in which the front edge thereof is aligned with the hanging portion 47A of the front frame 47 of the support frame 45. A cold air passage 66 having a predetermined interval is also secured between the front edge of A and the back surface of the heat insulating door 15 that is closed.

When the strip-shaped regenerator B is supported on the stand rack 50, the strip-shaped regenerator B is placed in a posture in which the long side of the cross section is set up horizontally and tilted horizontally, and the adjacent support frame 55 in the upper stand rack 50. The strip-shaped cold storage agent B is received by the two rear receiving frames 62 and the rear edge frame 54 in the rear side region when the rear edge of the connecting frame 59 is inserted. While being supported, the support frame 55 is supported in the form of being leaned between the portions on the back side of the recessed portion 58 in the adjacent support frame 55.
When supporting the front side region, the strip-shaped cold storage agent B is inserted between the adjacent support frames 55 in the same posture as described above, and the rear edge side is supported by the rear region. When the front edge is pushed to a position where the front edge is aligned with the front frame 57 of the support frame 55, the strip-shaped cold storage agent B is separated from the front two receiving frames 62 and the main body frame 51. While being received by the front edge, the support frame 55 is supported in a state of being leaned between the portions on the nearer side than the recessed portion 58 in the adjacent support frame 55.

Similarly to the above, the lower stand rack 50 is also supported in a form in which the strip-shaped regenerator B is leaned on the near side and the far side.
At this time, between the rear edge of the strip-shaped regenerator B supported on the back region of the stand rack 50 and the back wall 12A, and the front edge of the strip-shaped regenerator B supported on the front region, A cold air passage connected to the cold air passages 65 and 66 is ensured between the closed back surface of the heat insulating door 15.

When the storage of the regenerators A and B is completed, the cooling operation is started after the heat insulating door 15 is closed. That is, when the refrigeration apparatus 17 and the internal fan 26 are driven, cold air is generated while the internal air sucked from the suction port 22 passes through the cooler 25 as indicated by the arrow in FIG. Then, after the cold air is blown out from the blower outlet 23 toward the cold air passage 65 on the surface of the back wall 12A, the cold air is blown forward through the cool storage agents A and B supported by the racks 40 and 50 of each stage, and thereafter Circulating supply is performed so as to rise along the cold air passage 66 on the back surface of the heat insulating door 15, and the stored cold storage agents A and B are thereby frozen.
Since the cool air passages 65 and 66 are secured on the front side and the rear side of the stored cool storage agent group, the cool air is smoothly circulated and supplied over the entire area of the freezing chamber 12 so that all the cool storage agents A and B are uniform. And frozen at high speed.
When the freezing is completed, the heat insulation door 15 is opened, and then the cold storage agents A and B may be taken out from the corresponding racks 40 and 50 by a procedure reverse to that of the storage.

  According to the present embodiment, in the portion where the mat-shaped regenerator A is suspended and supported on the hanger rack 40, the control frame 49 provided on the rear edge side of the hanger rack 40 further exceeds the mat-type regenerator A on the back side. For the mat-like cool storage agent A on the near side, the front edge is aligned with the front frame 47 (hanging portion 47A) of the support frame 45, and the mat-like cool storage agent A is supported in a group. Cold air passages 65 and 66 are secured on the rear side and the front side of A. Therefore, the cool air can be smoothly circulated and supplied over the entire storage area of the mat-like cool storage agent A, and the entire cool storage agent A can be frozen uniformly and at a high speed.

When the folded mat-like cold storage agent A is hung on the horizontal frame 46 of the support frame 45, the mat-like cold storage agent A is fastened to the near side, but the front frame 47 (hanging portion 47A) of the support frame 45 is used as a mark. The front-side cool air passage 66 can be reliably secured only by performing an operation such that the front edge is aligned with the mark and hung on the horizontal frame 46.
In addition, on the back side, a cold air passage is secured on the back side of the restriction frame 49 provided on the hanger rack 40, but the hooked portion is provided to be hooked on the shelf receiver 32 provided on the back wall 12A. 43 is provided in a form projecting to the back side from the regulation frame 49, so that the existing frame can be applied to the shelf column 30 and the shelf receiver 32, and the gap between the regulation frame 49 and the back wall 12A can be widened. That is, a wide cold air passage 65 can be secured on the back surface side.
The restriction frame 49 also functions as a reinforcing material and can contribute to the shape maintenance of the hanger rack 40.

Since the front frame 47 of the support frame 45 of the hanger rack 40 is formed in a shape that hangs down from the front end of the horizontal frame 46 and then bent to the back side, for example, it is folded in two and suspended on the front side of the horizontal frame 46. In the lowered mat-shaped regenerator A, the inclined portion 47B of the front frame 47 is inserted between the portions distributed on both sides in the front lower portion, so that a gap is secured and between the portions distributed on both sides. It becomes easy for cold air to pass through and the cooling effect of the regenerator A is further enhanced.
The hanger rack 40 is mounted so as to be immovable in the front-rear and left-right directions by fitting the four corners of the bottom surface to the latching pieces 35 of the shelf receiver 32 and latching them. There is no position shift in the front-rear direction due to taking in and out. Therefore, as long as the mat-like regenerator A is suspended and supported in the above-described form, appropriate cool air passages 65 and 66 can be secured in the front and rear.
