JP 2011-7389 A

In the freezer as described above, in order to freeze a large amount of cold storage agent at a time, it is effective to pack the racks vertically and arrange them in multiple stages, but the interval between the upper and lower racks becomes narrower. Therefore, there is a problem that it is difficult to hang the cold storage agent folded in half on the upper frame of the support frame.
The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a rack that can easily perform an operation of supporting a cold storage agent.

The present invention is a structure in which a plurality of support frames each having a rectangular shape for folding and supporting a sheet-like cold storage agent in a folded manner are arranged side by side at predetermined intervals, and are arranged in a plurality of stages in a freezer. The rack mounted in this manner is characterized in that a chamfered shape is applied to the lower or upper corner of the front frame of the support frame.
When the cold storage agent folded in half is inserted between the upper and lower racks and hung on the support frame of the lower rack, the cold storage agent is opened so that the inserted portion of the cold storage agent spreads toward the front. It becomes easy to insert and pull on the support frame.

The following configuration may also be used.
(1) The support frame includes a horizontal frame that suspends the regenerator, a rear frame that is suspended from the back end of the horizontal frame, and a front frame that is suspended from the front end of the horizontal frame and then bent to the back side. The rack is formed by arranging the support frames in parallel and connecting the lower ends of the support frames to the main body frame.
When the racks are mounted in a plurality of stages, a space is formed on the front side above the front end of the horizontal frame in the support frame of the lower rack and between the bent portions of the front frame of the upper rack. The cold storage agent folded in half is inserted and hung through a wide space with respect to the horizontal frame of the support frame of the corresponding rack. In addition to facilitating the work of hanging on the support frame, the length of the horizontal frame on which the cool storage agent is actually hung can be increased, so that the cool storage agent can be suspended more stably.

(2) Between the front frame and the rear frame of the support frame, abuts against the opposed surfaces of the suspended cool storage agent on both sides, and the opposed surfaces of the divided portions approach each other. A regulation bar is provided to regulate overhanging in the direction of the movement.
The cold storage agent is a gelling agent filled in a resin sheet, and when frozen, the gelling agent expands in volume and becomes hard with increased thickness. Therefore, when the regenerator is frozen in a state suspended from the front frame of the support frame, the opposing surfaces of the parts distributed to both sides of the regenerator are in a state of protruding in a direction approaching each other, If it does so, when extracting a cool storage agent along a horizontal frame, there exists a possibility that a cool storage agent may be caught in a front frame.
On the other hand, in this configuration, the opposing surfaces of the parts distributed on both sides of the cool storage agent are restricted from protruding in the direction approaching each other by hitting the regulation bar, in other words, the parts distributed on both sides are placed on the front frame. On the other hand, the frozen regenerator that is held at the left and right sides viewed from the front is smoothly drawn out along the regulation bar without being caught by the front frame.

  If the rack of this invention is used, the operation | work which suspends and supports a cool storage agent on a support frame can be performed easily.

The stand rack 50 is roughly composed of a main body frame 51 formed of a metal wire such as a steel wire, a plurality of support frames 55 (15 pieces in the figure), and a receiving frame 62.
The main body frame 51 is composed of a three-sided frame 52 that forms a planar portal composed of a front edge and left and right side edges, and a rear edge frame 54. At the back end portions of the left and right side edges of the three-way frame 52, a hooked portion 53 that is bent inwardly is formed, and the front ends of the folded portions 53A of the hooked portion 53 face each other. It is bent at right angles to the direction to be bent (bent portion 53B). The rear edge frame 54 has a length extending between the left and right side edges of the main body frame 51. The rear edge frame 54 is placed between the inner ends of the bent portions 53B of the left and right hooked portions 53, and is inserted between the rear end portions of the left and right side edges of the main body frame 51 and joined by welding. Thus, the main body frame 51 is formed.
The main body frame 51 is formed in a planar rectangular shape having a width substantially equal to the entrance of the freezing chamber 12 and a depth dimension that is smaller than the depth of the freezing chamber 12 by a predetermined dimension, and is formed at the far ends of the left and right side edges. The hooked portion 53 has a shape protruding rearward by a predetermined dimension from the rear edge frame 54.

The support frame 55 has a shape in which a front frame 57 is integrally formed at a front end of a horizontal frame 56 extending in the front-rear direction, and a predetermined depth is provided in a predetermined length region in a central portion in the length direction of the horizontal frame 56.

Such a temporarily assembled support frame 55 is placed on the main body frame 51, and the tip of the bent portion 57A of the front frame 57 in each support frame 55 is applied to the upper surface of the front edge of the main body frame 51 and fixed by welding. Is done. At this time, since the leg frames 60 at both ends of the connecting frame 59 correspond to the slightly front side of the protruding ends of the hooked portions 53 formed at the left and right rear ends of the main body frame 51, the lower side of the leg frame 60 Is placed on the hooked portion 53 and fixed by welding.

  Further, four receiving frames 62 are provided so as to extend between the left and right side edges of the main body frame 51. The two receiving frames 62 on the front side are arranged at a position slightly inward from the front edge of the main body frame 51 and a position near the front edge of the recessed portion 58 and are fixed by welding. The two rear receiving frames 62 are respectively arranged at a position near the rear edge of the recessed portion 58 and at an intermediate position between the same position and the rear edge frame 54, and are similarly fixed by welding.

As described above, in the region slightly inside the left and right side edges on the upper surface of the main body frame 51, the 15 support frames 55 shown in the figure are provided side by side in the left-right direction at regular intervals, and the front side of each support frame 55 A depth region from the front edge of the front frame 57 to the tip of the bent portion 57A of the front frame 57 protrudes to the front side of the front edge of the main body frame 51, and to the left and right rear ends of the main body frame 51. A predetermined region on the protruding end side of the formed hooking portion 53 is projected from the position of the connecting frame 59 and the leg frame 60 to the back side. Also, two receiving frames 62 are provided in each of the regions divided into the front side and the back side.
Here, the length dimension in the front-rear direction of the horizontal frame 56 in the support frame 55 is a little less than twice the length of the strip-shaped regenerator B, and the height dimension to the horizontal frame 56 is that of the strip-shaped regenerator B. The dimension is slightly smaller than the width. The interval between the two front receiving frames 62 is about 60% of the length of the strip-shaped regenerator B, and the interval between the two rear receiving frames 62 is about 2/3 of the interval between the front sides. It is.

  The strip-shaped regenerator B is received by the two rear receiving frames 62 and the rear edge frame 54 in the back region, and between the portions on the back side of the recessed portions 58 in the adjacent support frames 55. In the region on the near side, the front side is supported by the two receiving frames 62 on the front side and the front edge of the main body frame 51, and the portion on the nearer side than the recessed portion 58 in the adjacent support frame 55 is supported. 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.

The effect of this embodiment is as follows. When the mat-shaped regenerator A is supported on the lower hanger rack 40 among the hanger racks 40 arranged vertically, the folded mat-shaped regenerator A is attached to the upper and lower hanger racks 40 as shown in FIG. The support frame 45 of the lower hanger rack 40 is inserted between the front and rear sides of the support frame 45 of the lower hanger rack 40, but above the front end of the horizontal frame 46 in the support frame 45 of the lower hanger rack 40. Since the space S that extends to the near side is formed between the inclined portion 47B of the frame 47, it is easy to insert and fold the mat-shaped cold storage agent A into the horizontal frame 46 of the support frame 45. As a result, the storage time of the cool storage agent can be shortened.
The space S for facilitating the insertion described above is configured by providing the front frame 47 with an inclined portion 47B, and the length of the horizontal frame 46 on which the mat-like cold storage agent A is actually applied is set to be large. Therefore, the mat-like regenerator A can be suspended and supported more stably.

<Embodiment 2>
FIG. 18 shows a second embodiment of the present invention. In the hanger rack 40W of the second embodiment, the lower end portion of the front frame 47 in the support frame 45 is an arc-shaped portion 47C.
Above the front end of the horizontal frame 46 in the support frame 45 of the lower hanger rack 40W among the upper and lower hanger racks 40W, is in front of the arcuate portion 47C of the front frame 47 of the upper hanger rack 40W. A space S extending to the side is formed. Similarly, the mat-like cold storage agent A folded in half is easily inserted and hung on the horizontal frame 46 of the support frame 45.

<Embodiment 3>
FIG. 19 shows Embodiment 3 of the present invention. In the hanger rack 40X of the third embodiment, a corner portion where the upper end of the front frame 47 and the front end of the horizontal frame 46 intersect in the support frame 45 is an inclined portion 47D so as to be chamfered. Similarly, a space S is formed in front of the horizontal frame 46 in the support frame 45 so as to expand toward the front side.
The inclined portion 47D may have a gentler slope and a longer depth than those described above, or may be an arcuate portion.

<Embodiment 4>
A fourth embodiment of the present invention will be described with reference to FIGS.
When the cold storage agent is frozen, the gelling agent expands in volume and becomes hard with increased thickness. Therefore, as illustrated in the first embodiment, when the mat-shaped regenerator A is suspended on the horizontal frame 46 of the support frame 45 of the hanger rack 40 and frozen, the mat-shaped regenerator supported particularly on the back side. In A, the opposing surfaces of the parts distributed on both sides are projected in a direction approaching each other, and when the mat-like cold storage agent A on the back side is pulled out along the horizontal frame 46, the mat-like cold storage agent A may be caught on the front frame 47 of the support frame 45.
In the hanger rack 40Y of the fourth embodiment, the restriction bar 70 is horizontally passed between the support frame 45 and the rear frame 48 of the inclined portion 47B of the front frame 47 and fixed by welding.

When the mat-shaped regenerator A folded in half on the support frame 45 of the hanger rack 40 is suspended, the regulation bar is placed between the opposing surfaces of the lower part of the regenerator A distributed to both sides. It becomes a state where 70 entered, and it is controlled that an opposing surface protrudes in the direction which approaches mutually. In other words, the portion distributed to both sides is held at positions deviating from the left and right sides when viewed from the front with respect to the front frame 47, and the frozen mat-like cold storage agent A is along the regulation bar 70 so as to follow the front frame 47. It is pulled out smoothly without being caught by
Moreover, a clearance gap is ensured between the parts distributed to both sides in the mat-like regenerator A, and cold air circulates in the clearance gap to increase the freezing speed.

<Embodiment 5>
22 and 23 show the fifth embodiment.
As the form of the mat-shaped regenerator A1, there is a triple type in which three strip-shaped regenerator members a are connected. In this case, the mat-shaped regenerator A1 has 2 on one side as shown in FIG. The cold storage members a are distributed and suspended so that the cold storage member a comes to the other.
In the hanger rack 40Z according to the fifth embodiment, the restriction bar 71 is provided between the rear frame 48 and the rear frame 48 between the rear frame 48 and the support frame 45. Passed horizontally and fixed by welding.

  When the triple-type mat-like regenerator A1 is suspended from the support frame 45 of the hanger rack 40Z, as shown in FIG. 23, the restriction bus bar 71 is placed between the opposed portions distributed on both sides. In this state, the opposing surfaces are restricted from projecting in the direction of approaching each other, and similarly, the portions distributed to both sides are held at positions deviating from the left and right sides when viewed from the front with respect to the front frame 47. Therefore, the frozen mat-like regenerator A1 is drawn out smoothly along the regulation bar 71 without being caught by the front frame 47.

The hanger rack 40Z according to the fifth embodiment also hooks the mat-shaped regenerator on the front frame 47 even when hanging and supporting a double mat-type regenerator that connects two strip-shaped regenerator members a. It is effective as well for smooth removal without any problems.
In addition, you may make it provide the regulation bar 70 illustrated in the said Embodiment 4 collectively with respect to the hanger rack 40Z.
