  The quick freezer R employed in the present embodiment is a freezer (cooling storage) that rapidly freezes the regenerator 26 stored in the storage (storage chamber) 3, for example, delivery of items requiring cooling such as food. Installed on the base. The quick freezer R has a main body constituted by a heat insulating box 2 that opens to the front surface, and the inside of the heat insulating box 2 is used as a storage room (inside) 3. The front opening 5 of the heat insulation box 2 is closed by a door (not shown) so as to be opened and closed.

  A partition plate 8 is provided on the inner wall 6 on one side in the storage chamber 3 with a predetermined interval. As a result, a cooling chamber 7 extending up and down the storage chamber 3 is formed between the partition plate 8 and the inner wall 6 on one side. In the cooling chamber 7, a cooler 12 that constitutes the cooling device 10 is disposed substantially at the center in the vertical direction of the heat insulating box 2. Above the cooler 12, an upper blower 13 for circulating cool air that discharges cool air in the cooling chamber 7 into the storage chamber 3 is disposed.

  On the storage chamber side surface of the partition plate 8 constituting the storage chamber 3 as described above and the inner wall 9 on the side where the partition plate 8 is not provided, shelf posts 24 are provided in the front and rear directions (FIG. 1 shows only the shelf post 24 on the front one side). A plurality of engagement holes 24 </ b> A are formed in the shelf columns 24 in the vertical direction, and a plurality of net shelves 25 are installed on the shelf columns 24 above and below the storage chamber 3. On each net shelf 25, a cold storage agent freezing rack 30 in which a plurality of the cold storage agents 26 in this embodiment are stored is placed.

  Hereinafter, the cool storage agent freezing rack 30 and the cool storage agent 26 of the present invention will be described in detail with reference to FIGS. 3 to 9. 3 is a front view of the rack 30, FIG. 4 is a left side view of FIG. 3, FIG. 5 is a top view of FIG. 3, and FIG. 7 to 9 are perspective views of the cold storage agent freezing rack 30 showing a state in which the cold storage agent 26 is housed.

  For example, as shown in FIG. 7, the cool storage agent 26 in the present embodiment includes a plurality of cool storage members 27 that are formed in a rectangular shape and are arranged in parallel at intervals, and the resin sheet 28 is used to connect the cool storage members 27. In addition to covering, the gaps between the cold storage members 27 and the outer edge portions are brought into close contact with each other so as to be integrally connected. Thereby, between the some cool storage member 27 arranged in parallel, the connection part 29 which has the flexibility which connects each cool storage member 27 mutually is formed.

  In addition, the cool storage agent 26 employ | adopted in a present Example connects the four cool storage members 27, and the connection part 29 connects in the longitudinal direction of each cool storage member 27. FIG. For example, as shown in FIG. 8, the cold storage agent 26 is folded at the central connecting portion 29, that is, in a folded state, the length of two sides perpendicular to the longitudinal direction of the cold storage member 27 is The cold storage member 27 is configured to have a dimension shorter than the length of the side in the longitudinal direction. Therefore, when the folded part when the cold storage agent 26 is folded in two is taken as the top, the length in the vertical direction (vertical) is a rectangular body shorter than the length in the horizontal direction (horizontal), and the bent part is In the case of the vertical direction, the length in the vertical direction (longitudinal) is longer than the length in the horizontal direction (horizontal).

  On the other hand, the cool storage agent freezing rack 30 includes a plurality of first support frames 31, a plurality of second support frames 41, and a plurality of connecting wires (connecting members) 51. . The first support frame 31 is a substantially rectangular frame member composed of four sides of an upper side 32, a lower side 33, a front side 34, and a rear side 35. Similarly, the second support frame 41 includes an upper side 42 and a lower side 43. A substantially rectangular frame member composed of four sides of a front side 44 and a rear side 45.

  In the present embodiment, the first support frame 31 has a predetermined dimension than the second support frame 41. In the present embodiment, the first support frame 31 is approximately half the vertical dimension of the one cold storage member 27 of the cold storage agent 26. It is formed low. Further, the upper and lower sides 32, 33 and 42, 43 of each support frame 31, 41 are formed corresponding to the dimension in the depth direction of the storage chamber 3, and in this embodiment, the dimension in the depth direction is The size in the longitudinal direction in which the cold storage agent 26 is folded in half and the sum of the dimensions in the direction orthogonal to the longitudinal direction are approximately the same.

  The first support frame 31 and the second support frame 41 are alternately arranged at a predetermined interval, and the lower sides 33 and 43 are arranged in a parallel direction of the support frames 31 and 41 (left and right direction from the front). ) Are connected by a plurality of lower side connecting wires 51. In addition, in a present Example, the space | interval with the two lower side connection wire materials 51 and 51 arrange | positioned at the front side becomes narrower than the space | interval with the two lower side connection wire materials 51 and 51 arrange | positioned at the back side. Are arranged as follows. In addition, the number of the said lower side connection wire 51 is not limited to this.

  The rear sides 35 and 45 of the first support frame 31 and the second support frame 41 that are alternately arranged with a predetermined interval are arranged in the parallel direction of the support frames 31 and 41 (left and right direction from the front). ) Are connected by a plurality of rear side connecting wires 52, 52.

  The support frames 31 and 41 and the connecting wires 51 and 52 are all made of a wire made by applying a polyethylene coating to a metal wire. For example, the connecting wires 51 and 51 are connected to the support frames 31 and 41. , 52 are connected by welding, and then the whole is coated with a polyethylene coating.

  In the present embodiment, four first support frames 31 and four second support frames 41 are alternately arranged, and the interval between the support frames 31 and 41 is the thickness dimension of the regenerator 26. (In this case, since it is folded in two, it is at least twice the thickness dimension of the cold storage member 27).

  At this time, when the cool storage agent freezing rack 30 is placed in the storage chamber 3 with the first and second support frames 31 and 41 extending forward and backward, the cool storage agent freezing rack is mounted. The left-right dimension of 30 is configured to be smaller than the left-right width dimension of the storage chamber 3 by a predetermined dimension. Therefore, in a state where the cool storage agent freezing rack 30 is placed on the net shelf 25 of the storage chamber 3, the support frames 31 and 41 located on both sides of the cool storage agent freezing rack 30, and the inner wall 9 of the storage chamber 3, or A space larger than the thickness of the regenerator 26 is formed between the inner surface of the partition plate 8 (the surface on the storage chamber 3 side).

  Further, one side of the first support frame 31, in this embodiment, the front side 34, has a substantially central portion recessed toward the inside (in this case, the rear side 35) (bently formed in a substantially U shape). ) A recessed portion 36 is formed (presents a recessed shape). In this embodiment, the recessed portion 36 is formed to extend from the front side 34 to a position retracted to the vicinity of the approximate center of the support frame 31. And between this upper side 32 and the lower side 33, the position which avoided the said recessed part 36, the auxiliary | assistant edge | side 37 which is located between the recessed part 36 and the rear side 35 in this embodiment, and extends up and down is provided. It has been.

  Further, a concave portion 36 formed in the first support frame 31 is formed on one side of the second support frame 41 arranged adjacent to the first support frame 31, in this embodiment, on the front side 44. In the same manner as above, a recessed portion 46 (formed in a substantially U shape) that is recessed inward (in this case, the rear side 45 side) is formed (presents a recessed shape).

  At this time, the recessed portion 46 of the second support frame 41 has the same position as the recessed portion 36 formed on the first support frame 31 on the projection surface in the direction in which the support frames 31 and 41 are arranged in parallel. They are formed to have the same size. Thereby, each support frame 31 and 41 will have each recessed part 36 and 46 formed in the substantially the same position in the parallel direction.

  Further, the second support frame 41 is also positioned between the upper side 42 and the lower side 43 so as to avoid the concave portion 46, in this embodiment, between the concave portion 46 and the rear side 45. An auxiliary side 47 extending in the direction is provided.

  With the above configuration, a method of holding each regenerator 26 in the regenerator freezing rack 30 will be described with reference to FIGS. 7 to 9. The cool storage agent freezing rack 30 may store and hold the cool storage agent 26 in a state of being taken out from the freezer R, but the front sides 34 and 44 of the support frames 31 and 41 are on the door side (front opening side). ) And may be performed in a state of being placed on the net shelf 25 of the storage chamber 3.

  First, in this case, the cool storage agent 26 according to the present embodiment is folded in half around a connecting portion 29 (the connecting portion 29 becomes a bent portion) located in the center, and the connecting portion 29 (the bent portion). Is hung on (hangs on) the upper side 32 of the first support frame 31 and the upper side 42 of the second support frame 41. In this embodiment, in order to hold a larger amount of the regenerator 26, the regenerator 26 hung on each support frame 31, 41 is positioned so that its rear end is located near the rear sides 35, 45 of the support frame. Multiply.

  At this time, as described above, the recessed portions 36 and 46 that are recessed inward are formed on the front sides 34 and 44 of the support frames 31 and 41. Therefore, when moving the cool storage agent 26 in the depth direction, fingers can be inserted between the support frames 31 and 41 without hindrance, and the front sides 34 and 44 of the support frames 31 and 41 are not obstructive in the extraction work.

  The first support frame 31 and the second support frame 41 have different height dimensions, but the positions where the concave portions 36 and 46 are formed are the same on the projection plane in the parallel direction. It is considered as a position. Therefore, even if the distance between the support frames 31 and 41 is narrow enough to insert fingers, the front sides 34 and 44 of the adjacent support frames 31 and 41 do not get in the way, and the fingers can be inserted without hindrance. The delivery operation of the regenerator 26 held on the back side can be performed.

  In particular, in this embodiment, the regenerator 26 in a state of being hung on the back side of the upper sides 32 and 42 of the support frames so that the bent portions (connecting portions 29) are on the support frames 31 and 41, respectively. Concave portions 36 and 46 are formed extending rearward (inward) from the front end. Therefore, when taking out the cool storage agent 26 in a state of being hung on the support frames 31 and 41, fingers are inserted into the recessed portions 36 and 46, and the support frame 31 and 41 are arranged separately on one side and the other side. The cold storage agent 26 can be easily taken out by grasping the front end of the cold storage agent 26 and pulling it out to the near side. At this time, since the front end of the regenerator 26 does not move to the rear of the recessed portions 36 and 46 of the support frames 31 and 41, the front sides 34 and 44 do not get in the way and a smooth feeding operation is realized. It becomes possible.

  In the present embodiment, since the reinforcing sides 37 and 47 are provided at positions where the recessed portions 36 and 46 of the support frames 31 and 41 are avoided, a relatively heavy cold storage agent 26 is hung on the support frames 31 and 41. Even if it is hung, the strength of the suspended upper sides 32 and 42 of the support frame can be improved, and the regenerator 26 can be stably held.

  As shown in FIG. 7, the cold storage agent 26 is hung on each of the first support frame 31 and the second support frame 41, so that the four cool storage agents 26 are attached to the first support frame 31. The four cool storage agents 26 are alternately applied to the two support frames 41, and a total of eight cool storage agents 26 are held by the support frames 31 and 41.

  Each of the support frames 31 and 41 is hung on the upper sides 32 and 42 of the support frames 31 and 41 with the connecting portion 29 serving as a bent portion facing upward. A clearance allowing the flow of cold air is formed between the cold storage member 27 located on the side and the cold storage member 27 located on the other side, and the freezing efficiency inside the cold storage agent can be improved.

  In this embodiment, in this state, the first support frame 31 has a height dimension lower than that of the second support frame 41, and the first and second support frames 31, 41 have a predetermined interval. Are arranged alternately. Therefore, as for the cool storage agent 26 hung on the 1st support frame 31 and the 2nd support frame 41, the height difference is formed in the upper end parts of these cool storage agents 26, as FIG. 8 shows. Therefore, compared with the case where the upper end parts of these regenerators 26 are hung at the same height, the regenerators hung on the second support frame 41 adjacent to the regenerator 26 hung on the second support frame 41. A large space is formed in the upper part between the coolant 26 and the cool air circulating above each of the support frames 31 and 41 is stored on the first support frame 31 disposed below the cool storage agent. It becomes easy to descend to 26. Similarly, at the lower part of each support frame 31, 41, there is a large gap in the lower part between the cool storage agent 26 hung on the first support frame 31 and the cool storage agent 26 hung on the adjacent first support frame 31. The cold air rising from below the support frames 31 and 41 is likely to rise toward the cool storage agent 26 hung on the second support frame 41 arranged on the upper side.

  Thereby, even if it expands itself by freezing and the thickness dimension increases, the circulation of the cold air to the cold air passage formed in the gap between the cold storage agents 26 arranged between the same support frames 31 and 41 is prevented. It becomes possible to promote the cold air circulating in the storage chamber 3 to the cool storage agent 26 hung on the support frames 31 and 41. Therefore, when many cold storage agents 26 are frozen at once, efficient freezing can be realized.

  In particular, in the present embodiment, as described above, the cold storage agent 26 connects the four cold storage members 27 arranged in parallel to each other by the flexible connection portions 29. The folded portion is folded in half, and the folded portion is placed on the support frames 31 and 41 with the folded portion as the top. Therefore, the two cold storage members 27 connected by the connecting portion 29 are arranged on one side of each support frame, and the two cold storage members 27 connected by the connecting portion 29 are arranged on the other side of the support frame. .

  As described above, in this embodiment, the height difference between the first support frame 31 and the second support frame 41 is approximately half of the vertical dimension of the cold storage member 27. Therefore, the cool storage members 27 that are hung on the support frames 31 and 41 and are disposed between the same support frames 31 and 41 are adjacent to each other with a height difference of approximately half of the vertical dimension of each of the cool storage members 27. It becomes.

  Thereby, even if each cold storage member 27 and 27 expand | swells by freezing, the position where the expansion coefficient is high can be shifted and arrange | positioned, and cold air | flow distribution between the cool storage agents 26 hung on each support frame 31 and 41 adjacently Can be ensured.

  In particular, the two cold storage members 27, 27 arranged on one side of the support frame are connected by a connection portion 29 that is formed thinner than the cold storage member 27, so the height position of the connection portion 29 is also the same. Therefore, they are adjacent to each other with a height difference of approximately half of the vertical dimension of the regenerator 27. Therefore, the cold air passage formed by the thin connecting portion 29 can be set to a height position shifted vertically between the adjacent cold storage agents 26, and also by this, the gap of the cold air flow between the adjacent cold storage agents 26 Can be effectively secured.

  In addition, when only the usage mode for holding the cold storage agent 26 by hanging on the support frames 31 and 41, since each of the cold storage agents 26 is arranged at a position where the vertical position is shifted, The dimension between the support frames 31 and 41 may be smaller than twice the thickness dimension of the cold storage member 27.

  In addition, as described above, the cold storage agent freezing rack 30 is placed on the net shelf 25 of the storage chamber 3 so that the support frames 31 and 41 extend in the front-rear direction. In a state of being stored in the rack 30, a gap larger than the thickness dimension of the cold storage agent 26 (cool storage member 27) is formed between both sides of the rack 30 and the inner wall 9 of the storage chamber 3. That is, as shown in FIG. 2, the interval between the first support frame 31 and the inner wall 9 constituting one side of the cold storage agent freezing rack 30 and the second side constituting the other side of the cold storage agent freezing rack 30. The gap between the support frame 41 and the surface of the partition plate 8 on the storage chamber 3 side is larger than the thickness dimension of the cold storage member 27.

  Thereby, the cold storage agent 26 in a folded state is hung on the support frames 31 and 41 positioned on the inner wall 9 side and the partition plate 8 side of the storage chamber 3 of the cold storage agent freezing rack 30 in the front-rear direction. Can do. And in the state which the said cool storage agent 26 was hung, the clearance gap for cold air | flow distribution can be formed between the said cool storage agent 26 and the storage chamber 3 inner wall 9 or the partition plate 8. FIG. Thereby, the cool air circulation in the whole storage chamber 3 can be ensured, and the freezing efficiency of the regenerator 26 can be improved.

  In the present embodiment, as described above, the rack 30 for freezing the regenerator has a longitudinal dimension (depth direction) of each of the support frames 31 and 41 in the longitudinal direction in which the regenerator 26 is folded in two. A dimension that is approximately equal to the sum of the dimension (the dimension in the front-rear direction when the bent part is on the top) and the dimension in the direction orthogonal to the longitudinal direction (the dimension in the front-rear direction when the bent part is substantially vertical) Has been. The interval between the support frames 31 and 41 is at least twice the thickness of the cool storage agent 26, that is, the thickness of the cool storage agent 26 folded at least in half.

  For this reason, the regenerator 26 that is hung on the support frames 31 and 41 is arranged substantially rearwardly, and the regenerator 26 that is folded in half is formed in the gap between the support frames 31 and 41 that are located on the front side. The bent portion (connecting portion 29) can be inserted in a substantially vertical state and held between the support frames 31 and 41. In the present embodiment, the first support frame 31 and the second support frame 41 are provided in total, so that a total of seven cold storage agents 26 in a folded state can be stored in the gap.

  As a result, when the front-rear width is restricted by the storage chamber 3 in which the cold storage agent freezing rack 30 is stored, the folded portion of the folded cold storage agent 26 is placed on the back side of the support frames 31 and 41. As shown in FIG. 1, the folded cool storage agent 26 is extended in the longitudinal direction on the front side of the support frames 31 and 41 so as to be within the interval between the support frames 31 and 41. Can be plugged into.

  Thereby, even if it is a limited storage space, the cool storage agent 26 can be efficiently held on the support frames 31 and 41, and more cool storage agents 26 can be frozen at a time.

  In the present embodiment, recessed portions 36 and 46 that are recessed inwardly are formed on the front sides 34 and 44 of the support frames 31 and 41 that constitute the regenerator freezing rack 30, and each support frame 3 is supported in the storage chamber 3. It arrange | positions so that the frames 31 and 41 may extend forward and backward, it folds into the support frames 31 and 41 in the back | inner side spaced apart from the door side (front opening 5 side), and the bending part (connecting part 29) was made upper. The cold storage agent 26 is hung in the state, and the cold storage agent folded in the front side, that is, the door side is inserted and held in the gaps between the support frames 31 and 41, but the present invention is limited to this. However, the support frames 31 and 41 may be formed in the same shape, and the cold storage agent contained in a rectangular container or the like is not folded and is not folded between the support frames 31 and 41. It may be inserted into the gap and held.

  Thereby, when taking out the cool storage agent held in the gap between the support frames 31 and 41, as described above, fingers are inserted into the recessed portions 36 and 46 and inserted between the support frames 31 and 41, respectively. The cold storage agent 26 can be easily taken out by grasping the front end of the cold storage agent 26 that is held and pulling it out to the near side. At this time, the front sides 34 and 44 do not get in the way, and a smooth delivery operation can be realized.

  Further, in this embodiment, the regenerator freezing rack 30 is stored in the storage chamber 3 of the quick freezer R opened to the front so that the support frames 31 and 41 extend in the front-rear direction. Is not limited to this, and for example, the storage rack of the cold storage agent freezing 30 is accommodated in a storage room of a flat so-called stocker that opens to the upper surface so that the support frames 31 and 41 extend in the vertical direction. The recessed portions 36 and 46 may be formed on the opening side, that is, the upper side. This also makes it possible to easily deliver the cold storage agent held between the support frames 31 and 41.
