JP 2011-7389 A

In the rack having the above structure, if the object to be supported is a cold storage agent having a different length, for example, if it is changed to a short-sized cold storage agent, it cannot be supported by the receiving frame. It is necessary to prepare separately a rack provided with receiving frames at intervals that can support the agent and use them separately.
If the receiving frame is provided at an interval that matches the short-sized cool storage agent, it may not be possible to stably support a relatively long ordinary cool storage agent, and the number of receiving frames may be increased. If the regenerator from long to short can be supported, it will lead to an increase in the weight of the rack and an increase in manufacturing cost, so it cannot be easily handled.
The present invention has been completed based on the above-described circumstances, and the purpose thereof is a rack that can stably support sheet-like cold storage agents having different lengths, although they are of a single type. Is to provide.

  The present invention is a rack that supports a sheet-like cold storage agent and is mounted in a freezer, and a plurality of support frames having horizontal frames extending in the front-rear direction are arranged in parallel at predetermined intervals. The front end portion and the rear end portion of the frame are supported in a state of being separated on the main body frame via the leg frames, and in the vicinity of the lower end portions of the front and rear leg frames, A receiving frame is arranged in an intersecting direction and connected to the main body frame, and the cool storage agent is leaned between the adjacent support frames while being received by the front and rear receiving frames at both ends in the length direction. When the rack is turned upside down, the cold storage agent lies across the horizontal frames inside the support frames arranged side by side. A structure in which an accommodation space that can be placed and accommodated in a posture is formed; and Characterized in place was.

The sheet-shaped cold storage agent having a dimension longer than the interval between the front and rear receiving frames is supported in a form in which the both ends in the length direction are leaned between adjacent support frames while being received by the front and rear receiving frames. . In the case of a cool storage agent shorter than the distance between the front and rear receiving frames, the rack is turned upside down and the cool storage agent is placed in the storage space and placed in a posture lying across multiple horizontal frames. Is done.
When supporting sheet-like cold storage agents having different length dimensions, it can be handled by using one type of rack in an upside down orientation.

The following configuration may also be used.
(1) The support frame includes a horizontal frame having a recessed portion at a substantially central portion in the length direction, and a leg frame suspended from a front end portion of the horizontal frame. The lower end side of the leg frame is connected to the front edge of the rectangular main body frame, while the rear end portion of the horizontal frame in each support frame is positioned above the rear edge side of the main body frame, thereby Two receiving spaces opened in the front and rear are formed, and in the vicinity of the front end portion and the rear end portion of each receiving space, the receiving frame that forms a pair in the front and rear is passed between the left and right side edges of the main body frame. Is provided.

The cool storage agent is supported by being leaned between the support frames while being received by the receiving frame in two regions on the back side and the near side of the recessed portion in the support frame. If it is turned upside down, a storage space for placing the cold storage agent on its side is formed in two front and rear regions.
The receiving frame functions as a reinforcing material. The recessed portion provided in the horizontal frame of the support frame is particularly convenient when the front end portion of the cool storage agent leaning on the back side region is picked and pulled out. The vertical frame that constitutes the recessed portion is effective for holding the cool storage agent in a leaning posture by restricting the cool storage agent from falling to the side by striking the lower side of the stored cool storage agent.

(2) A connecting frame connected across the rear end of the horizontal frame in each of the support frames is provided, and leg frames provided downward at both left and right ends of the connecting frame are the left and right side edges of the main body frame. The rear end of the horizontal frame in each support frame is disposed above the rear edge side of the main body frame.
When the cool storage agent is pushed into the inner region, the further pushing against the connecting frame is restricted. This is effective when a cool air circulation space is secured on the back side of the cool storage agent.

(3) Each said support frame is provided in the inclination attitude | position which swung the upper end side to the side by the predetermined angle by the front view.
The sheet-shaped regenerator is supported in an inclined posture aligned in one direction between the support frames. Therefore, a predetermined gap is ensured between adjacent cool storage agents, and the circulation of cold air is ensured. As a result, the cold storage agent can be frozen uniformly and at high speed over the entire area.

  If the rack of this invention is used, the sheet-like cool storage agent from which length differs can be each supported stably.

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.

20 and 21, when the stand rack 50 is turned upside down, the front frame 57 on the front end side of each support frame 55 and the vertical frame on the near side constituting the recessed portion 58 are provided. A front-side accommodation space 70 that is open to the upper surface is formed between the upper frame 63A and the upper frame 63B that forms the recessed portion 58 and the connection frame 59. A rear receiving space 71 is formed.
In each of the storage spaces 70 and 71, for example, a strip-shaped cold storage agent B1 having a shorter size than that described above can be placed and stored in a lying posture over a plurality of horizontal frames 56.

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. 18, the bottom surface of the freezing chamber 12 is formed with a concave surface 12C that is inclined downward 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, as shown in FIG. 2 and FIG. 18, the strip-shaped regenerator B is placed in a posture in which the long side of the cross section is set up horizontally and Inserted between adjacent support frames 55 in the stand rack 50, the pushing is stopped when the rear edge of the stand rack 50 hits the connecting frame 59. While being received by the receiving frame 62 and the rear edge frame 54, the support frame 55 is supported in a state of being leaned between 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 insulating door 15 is opened, and the cold storage agents A and B are taken out from the warehouse while being pulled out of the corresponding racks 40 and 50.
When removing the mat-shaped cold storage agent A from the hanger rack 40, first, the front edge portion of the mat-shaped cold storage agent A on the front side is grasped from both sides, and then pulled out toward the front side while sliding on the horizontal frame 56. The back-side mat-like regenerator A may also be removed by putting the hand in the back, grabbing the front edge of the regenerator A, and pulling it forward while sliding on the horizontal frame 56.

When removing the strip-shaped regenerator B from the stand rack 50, referring to FIG. 18, first, the upper corner of the front end of the strip-shaped regenerator B on the front side is adjacent to the adjacent support frame 55 (front frame). 57) Put your finger between them and pick it up, and drag it out as an oblique posture with the front end slightly lifted. As for the rear side refrigerating agent B on the back side, the front end faces the position of the recessed portion 58 of the support frame 55. It is only necessary to drag the part in a slanted posture with a slight lift.
By providing the recessed portion 58, the front end portion of the strip-shaped regenerator B can be easily picked even in the back of the freezing chamber 12 and can be easily pulled off.

  On the lower side, the strip-shaped cold storage agent B supported by the support area on the near side can be taken out as follows. That is, as shown in FIG. 19, when the upper corner portion of the front end of the strip-shaped regenerator B is picked and pulled slightly toward the front side, the rear end of the strip-shaped regenerator B is disposed in the support region on the front side. Since the direction changes to an oblique posture in which the front end rises while the rear end hits the concave surface 12C by exceeding the receiving frame 62 on the side, the front end portion that protrudes toward the front side and rises upward in the same strip-shaped regenerator B is renewed. Grab it and pull it out toward you.

Now, with respect to the strip-shaped cold storage agent B, there are cases where it is desired to freeze the short-sized strip-shaped cold storage agent B1 compared to the one shown above. For example, if the strip-shaped regenerator B1 is shorter than the interval between the front and rear receiving frames 62 in each supporting region, it cannot be supported, and even if it is not so short, it should be used so as to be placed across the receiving frames 62. It is necessary to carry out storage work, and the efficiency is low.
Therefore, when storing the short strip-shaped regenerator B1, as shown in FIGS. 20 and 21, the stand rack 50 is turned upside down and the four corners are set on the latching pieces 35 of the shelf receiver 32. Hang, position and install. In addition, when using the space in the freezing chamber 12 effectively, the height position of the shelf receiver 32 is changed suitably.
Then, since the accommodation spaces 70 and 71 opened on the upper surface are formed on the front side and the rear side, in the accommodation spaces 70 and 71, the short strip-shaped cold storage agent B <b> 1 is formed into a plurality of horizontal frames 56. It is only necessary to place and accommodate in a lying posture.

  As described above, according to the stand rack 50 of the present embodiment, a large number of the strip-shaped regenerators B can be aligned and supported in a leaning posture. , 71 are formed in so-called cages formed in the front and rear regions, respectively, and a short strip-shaped regenerator B1 can be placed and accommodated. That is, when supporting the strip-shaped regenerators B and B1 having different length dimensions, it is possible to use one type of stand rack 50 in an upside down posture.

The receiving frame 62 used to support the strip-shaped cold storage agent B in a standing manner also functions as a reinforcing material and can contribute to the shape maintenance of the stand rack 50.
In addition, the recessed portion 58 is formed in the horizontal frame 56 of the support frame 55 so that the accommodation spaces 70 and 71 of the upper surface opening can be formed in the front and rear directions when inverted upside down. In particular, it is convenient when the front end portion of the strip-shaped regenerator B leaned on the support region on the back side is picked and pulled out. The vertical frames 63A and 63B constituting the recessed portion 58 are effective in restricting the strip-shaped cold storage agent B from falling to the side by striking the lower side of the stacked strip-shaped cold storage agent B and holding the strip-shaped cold storage agent B in the leaning posture. is there.
Further, a connection frame 59 is provided between the rear ends of the horizontal frames 56 of the support frames 55. With such a structure, when the strip-shaped regenerator B is pushed into the inner region, the further pushing is restricted by hitting the connecting frame 59. This is effective when the cold air passage 65 is secured on the back surface side of the strip-shaped regenerator B.

<Embodiment 2>
FIG. 22 shows Embodiment 2 of the present invention.
In the stand rack 50 illustrated in the first embodiment, for example, when the relatively wide strip-shaped cold storage agents B2 are leaned side by side, the adjacent cold storage agents B2 are leaned so as to form a mountain shape in which the upper end sides are butted, and before freezing Since they are relatively soft, they may be supported in a surface-contact form over a wide range, and as a result, cold air does not pass through the points where they stick to each other, and there is a problem that the degree of freezing varies and the freezing speed decreases.

On the other hand, in this embodiment, the support frames 55 constituting the stand rack 50X take an inclined posture in which the upper end side is swung to a side (for example, the left side) by a predetermined angle in a front view, and are arranged at regular intervals. It is formed with.
In such a stand rack 50 </ b> X, the strip-shaped regenerator B <b> 2 is supported in an inclined posture aligned in one direction between the support frames 55. Therefore, a predetermined gap is ensured between the adjacent strip-shaped cold storage agents B2, and the circulation of cold air is ensured. As a result, it becomes possible to freeze the entire strip-shaped cold storage agent B2 uniformly and at a high speed.
