Invention of Claim 3 is the thing of Claim 1 or Claim 2, The both sides | surfaces of the direction along the parallel direction of the said cool storage agent are formed in the inclined surface of upper opening, On this inclined surface It is characterized in that the partition member is provided.
According to a fourth aspect of the present invention, there is provided the reinforcing bar on the bottom surface according to any one of the first to third aspects, and the reinforcing bar is disposed in the storage region of the cold storage agent. It has a characteristic where it exists.

  Invention of Claim 5 is the basket of Claim 3, Comprising: In the thing with which the parallel direction of a cool storage agent was orient | assigned to the shelf network from the front side in the attitude | position which faced back and forth, Is characterized in that a handle is provided and only the upper side of both end faces including the handle is formed to open outward.

According to a sixth aspect of the present invention, the basket according to the fourth aspect of the present invention is withdrawn from the front side on a shelf network arranged in a freezing room in which cold air is circulated and supplied in a posture in which the parallel direction of the regenerator is directed forward and backward The cool storage agent freezer as described above is characterized in that a protective cylinder is fitted to the reinforcing bar on the bottom surface of the basket.
In the invention of claim 7, the basket of claim 4 is taken in and out from the front side on a shelf network arranged in a freezing room in which cold air is circulated and supplied in a posture in which the parallel direction of the regenerator is directed back and forth, And in the cool storage agent freezer provided with a stopper for restricting the pushing of the basket at a fixed position on the shelf network, the shelf network faces a shelf bar facing the depth direction of the freezing chamber and a frontage direction. The reinforcing bars are formed in a lattice shape, and when the basket is placed at a fixed position, the reinforcing bars are positioned below the storage area for the regenerator in the basket. It has the characteristics in the place.

  In the invention of claim 8, a plurality of regenerators are stored in parallel in a basket having an open top surface, and the basket is placed on a shelf network arranged in a freezing room to which cold air is circulated and supplied. The basket in the regenerator freezer in which the agent is frozen, formed by assembling and welding a plurality of wires, adjacent to both side surfaces in the direction along the parallel direction of the regenerator In a method of manufacturing a partition member that is divided between matching cool storage agents and that has a partition member that secures a gap between these cool storage agents and that has an opening that allows the flow of cool air in the partition member. When at least each side portion of the basket is assembled first and integrated by welding, and then the integrated side surface portion and the wire constituting the other surface are assembled and fixed by welding. Furnace has a feature.

<Invention of Claim 1>
Since the cool storage agent is stored in the basket with a gap between each other by the partition member having an opening, the cold air blown into the freezing chamber circulates smoothly through the clearance between each cool storage agent and the opening of the partition member. And all the regenerators are frozen uniformly and efficiently. Since only the shape of the basket is changed, it can be handled relatively inexpensively, and the freezing chamber volume is not reduced.
<Invention of Claim 2>
Since the cold storage agent expands in volume when frozen, it may be pressed against the partition member, but the partition member can be elastically deformed. Therefore, when taking out the cold storage agent, the partition member is elastically deformed, that is, the resistance is increased. Can be taken out in a reduced state. That is, it is possible to efficiently take out the cold storage agent from the basket after freezing.

<Invention of Claim 3>
A gap is formed between the cool storage agents in a state where the partition member is divided into the lower corners of the adjacent cool storage agents. The area of the cold air passage between the cold storage agents can be widened.
<Invention of Claim 4>
Since the reinforcing rod provided on the bottom surface of the basket is arranged at a position avoiding the cold air passage between the cold storage agents, the circulation of the cold air in the cold air passage is not hindered. Accordingly, it is possible to distribute the cold air uniformly over the entire cold air passage.

<Invention of Claim 5>
Since the left and right side surfaces in the direction along the parallel direction of the regenerator in the basket are formed so as to open upward, the front and rear end surfaces intersecting with each other can also be opened, so that the baskets can be stacked while fitting over almost the entire height. . However, if the front and rear end faces are tilted upwards over the entire height, the total length will be longer.Therefore, it is necessary to shorten the total length in order to fit it without hitting the inner wall of the freezing chamber. Becomes shorter, and the storage capacity of the regenerator is substantially reduced.
Therefore, according to the present invention, since the upper side of both end faces including the handle in the basket is formed to open outward, the baskets can be stacked while fitting a part of the overall height, and the overall length can be kept small. In other words, each basket can be stacked with a low back when not in use, while minimizing the reduction in the storage capacity of the regenerator, and storage space can be saved.
In addition, since the handle is open to the outside, a large gap can be secured between the cool storage agent stored in the end portion, the handle can be easily grasped, and the basket can be easily taken in and out.

<Invention of Claim 6>
The basket is put in and out of the shelf network while sliding the protective cylinder fitted to the reinforcing bar on the bottom surface. Since the reinforcing bars of the basket are not directly rubbed against the shelf net, they are less likely to be damaged. Further, the sliding resistance can be reduced, and the basket can be inserted and removed smoothly.
<Invention of Claim 7>
When the basket is placed on the shelf net and pushed in and hits the stopper to reach a fixed position, the reinforcing rods that make up the shelf net are also placed in a position that avoids the cold air passage between the cool storage agents in the basket. The flow of cold air to the cold air passage is not hindered. Therefore, it can contribute to distribute | circulating cool air uniformly over all the cool air paths.

<Invention of Claim 8>
When the basket is formed by fixing the wire rod by welding, generally, the wire rod is assembled in a predetermined shape on a jig and fixed by welding. On the other hand, when the partition member is provided on the side surface, it is necessary to position the partition member with high precision in order to evenly leave the gaps between the regenerators, but the entire basket is assembled on a large jig as described above. It is difficult to position the partition member with high accuracy.
Therefore, in the present invention, both side surface portions of the basket including the partition member are assembled by welding after being assembled on a small jig, and then the integrated side surface portion and the wire constituting the other surface, Are assembled and fixed by welding to form the entire basket.
Since the side portion of the basket including the partition member can be assembled and welded on a small jig, the partition member can be positioned and arranged with high accuracy.

<Embodiment>
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the freezer 10 of the present embodiment has a freezer main body 11 formed of a vertically long heat insulating box with an open front, and the inside is made into a freezing chamber 12 at the four corners of the bottom surface. It is supported by the provided legs 13. The front opening of the freezing chamber 12 is partitioned by a partition wall 14 to form two upper and lower entrances 15, and a heat insulating door 17 is mounted so as to be swingable and openable.
A cooler chamber 20 is defined at a position near the back side of the ceiling of the freezing chamber 12, and a suction port 21 is formed at a position on the near side of the bottom surface, and an outlet 22 is formed at the back side. ing. A cooler 23 is accommodated in the cooler chamber 20 and connected to a refrigeration apparatus (not shown) installed in the machine chamber 19 on the upper surface of the freezer main body 11 by a refrigerant pipe to constitute a refrigeration cycle. At the same time, an internal fan 24 is mounted facing the suction port 21.

When the internal fan 24 is driven while operating the refrigeration apparatus, the indoor air in the freezing chamber 12 is sucked into the cooler chamber 20 from the suction port 21, and heat exchange is performed while the air flows through the cooler 23. Cold air is generated, and the cold air is blown out from the blower outlet 22 along the inner wall 12A of the freezing chamber 12, and the cold air is circulated and supplied into the freezing chamber 12 to be cooled.
During this time, for example, a temperature sensor (not shown) provided in the cooler chamber 20 detects the internal temperature, and the refrigeration apparatus and the internal fan 24 are controlled on and off based on the detected temperature, thereby freezing. The interior of the chamber 12 is maintained at a preset temperature (for example, about −30 ° C.).

In the freezing chamber 12, the regenerator A is accommodated in the basket 30, and, as will be described in detail later, the basket 30 is placed on the shelf network 60 in two upper and lower four stages. It is placed and supported.
The regenerator A is a known one in which a gelling agent is filled in a hard case made of resin such as polyethylene, and as a whole has a rectangular plate shape. As shown in FIG. 8, the cool storage agent A is stored side by side in the basket 30 in a posture in which the short side is vertically oriented, and here, for each basket 30, 14 cool storage agents A are stored. It is possible.

Next, the structure of the basket 30 will be described with reference to FIGS. The basket 30 is roughly formed in a shallow basket shape that is elongated in the front-rear direction (parallel direction of the regenerator A) and has an open top surface by assembling a metal wire such as a steel wire.
Specifically, the length in the front-rear direction is about the depth dimension of the freezing chamber 12, the width in the left-right direction is a little less than half the opening size of the freezing chamber 12, and the height is the height dimension of the regenerator A in the storage posture. It is a little less than half.

The left and right side surface portions 31 of the basket 30 are formed in a relatively steeply inclined posture with an inclination angle of about 70 degrees, and as shown in FIG. The distance between the upper edges of the cold storage agent A is slightly wider than the width dimension of the cold storage agent A, and the distance between the lower edges of the both side surface portions 31 is smaller than the width dimension of the cold storage agent A by a predetermined dimension.
Each side surface portion 31 has a configuration in which thirteen partition members 34 are passed between the inner surfaces of the upper and lower frames 32U and 32L with respect to the outer frame 32 elongated in the front-rear direction, with a predetermined interval in the front-rear direction. It is attached. Specifically, the partition member 34 is configured by a pair of wire rods 35 having a diameter smaller than that of the outer frame 32 being arranged in parallel with each other with an interval of about half of the thickness of the regenerator A. The partition member 34 is passed between the upper and lower frames 32U and 32L on the inner surface side of the outer frame 32 and fixed by welding with a space slightly larger than the thickness of the regenerator A as described above.

  By providing the partition members 34 on the left and right side portions 31 as described above, a total of 14 storage regions 38 for the regenerator A partitioned by the partition members 34 are spaced apart in the front-rear direction in the basket 30. Open and lined up. Here, since the partition member 34 is formed by a pair of wire rods 35 spaced apart from each other, the partition member 34 is provided with an opening 36 that allows cold air to flow through a gap between the wire rods 35. It will be. Furthermore, since both the wires 35 are thin, for example, elastic deformation is possible in the direction in which both wires 35 approach.

  The bottom surface portion 40 of the basket 30 includes three horizontal bars 41 passed between the lower surface sides of the lower frame 32L in the left and right side surface portions 31, and one crossed on the horizontal bars 41 in an orthogonal posture. And the vertical bar 42. Specifically, as shown in FIG. 5, the horizontal bar 41 corresponds to a storage area 38 that is one inward from both ends of the 14 storage areas 38 and a seventh storage area 38 from one end side. At the positions, they are respectively passed to the lower surface side of the lower frame 32L of the left and right side portions 31 and fixed by welding. Further, the vertical bars 42 are placed in an orthogonal posture as described above so as to connect the central portions of the horizontal bars 41 on the upper surface side of the three horizontal bars 41, and are fixed by welding.

  The front and rear end face portions 45 of the basket 30 are formed by passing an upper horizontal bar 46 and a lower horizontal bar 48 to the front frames 32F or the rear frames 32R of the left and right side surface portions 31. The upper horizontal bar 46 is passed between the outer surfaces of the front frames 32F or both rear frames 32R at positions lower by about 1/4 of the total height, while the lower horizontal bar 48 is connected to the front frames 32F or both It is passed between the outer surfaces of the rear frame 32R at a position that is about 1/3 of the total height from the lower end, and both ends of both horizontal bars 46, 48 are welded and fixed to the front and rear frames 32F, 32R. Yes.

  Here, as shown in FIG. 4, the lower horizontal bar 48 is in a straight posture parallel to the horizontal bar 41 arranged on the bottom surface part 40, whereas the upper horizontal bar 46 is formed on the bottom surface part 40. Except for the central portion in the length direction, which is comparable to the width dimension, the left and right ends are bent obliquely inward (inward bent portion 47). Therefore, when both ends of the upper horizontal bar 46 are fixed to the front frame 32F or the rear 32R of the both side surface parts 31 as described above, most of the center of the upper horizontal bar 46 excluding both ends in the length direction. However, as compared with the lower horizontal bar 48, it is in a state of projecting outward about twice the diameter of these bars.

A handle 50 is provided on the front and rear end face portions 45 described above. The handle 50 is formed by bending a wire rod into a gate shape, and is attached to the outer surface of the center portion in the width direction of the front and rear end surface portions 45. Specifically, the lower ends of the left and right leg pieces 51 of the handle 50 are applied to the lower horizontal bar 48, and the substantially central height portion is applied to a part protruding to the outside of the upper horizontal bar 46, and each is fixed by welding. A substantially upper half including the handle portion 52 at 50 protrudes upward from the upper horizontal bar 46.
In other words, the front and rear end surface portions 45 of the basket 30 are formed in a state where the upper side including the handle 50 is opened outward.

  An example of the manufacturing process of the basket 30 is as follows. First, as shown in FIG. 7, two side surface unit 31X, one bottom surface unit 40X, and two end surface unit 45X are small. Individually formed using a dedicated jig. The side surface unit 31X is formed by passing a predetermined number (13) of partition members 34 made of a pair of wire members 35 between the upper and lower frames 32U and 32L of the outer frame 32 and fixing them by welding. In the bottom unit 40X, three horizontal bars 41 are arranged at predetermined intervals, and a vertical bar 42 is placed on the upper surface and fixed by welding. In the end face unit 45X, the upper horizontal bar 46 and the lower horizontal bar 48 are arranged at a predetermined interval, and the handle 50 is applied to the outer surface of the unit to fix it by welding.

These units 31X, 40X, and 45X are assembled in a predetermined arrangement using a large jig, and a frame of the basket 30 is formed by welding predetermined portions. Thereafter, a resin coat such as polyethylene is applied to the framework of the basket 30 to complete the basket 30 shown in FIG.
Further, the protective cylinder 43 is rotatably fitted at the six horizontal bars 41 constituting the bottom surface portion 40 of the basket 30, specifically, at six convenient locations for each part divided on both sides of the vertical bar 42. . The protective cylinder 43 is formed of a thick resin tube having excellent wear resistance, such as Teflon (registered trademark), and a cut 44 is formed over the entire length. Therefore, it is fitted to the horizontal bar 41 while opening from the cut 44, and is closed by restoring elasticity and supported rotatably. As will be described later, when the cool storage agent A is stored, the upper surface of the fitted protective cylinder 43 is a vertical bar of the lower frame 32L of the side face 31 and the bottom face 40 so that the protective cylinder 43 is not crushed. It is set to be slightly below the upper surface of 42 (see FIG. 11).

  The regenerator A is stored in the basket 30 formed as described above. For example, as shown in FIG. 8, the cool storage agent A is stored sequentially from the storage area 38 on one end side so as to be dropped from above. As shown in FIGS. 10 and 11, the cold storage agent A has both left and right end portions of the lower end surface on the lower frame 32 </ b> L constituting the left and right side portions 31, and the center portion of the lower end surface is a vertical portion of the bottom portion 40. Each is placed on the rod 42, and almost the center height position of the left and right end faces is stored between the left and right upper frames 32U with little rattling. At this time, since the partition members 34 provided on the left and right side portions 31 are split between the adjacent cold storage agents A, as shown in FIG. Therefore, a clearance substantially equal to the width dimension of the partition member 34, that is, the cold air passage S is secured.

In detail, since the partition member 34 is shorter than the cold storage agent A and is formed on substantially the same plane as the left and right side portions 31 opened outward, the partition member 34 is formed of the adjacent cold storage agents A. It will be in a state of being broken into the corners on the lower side of the. Here, the fact that the left and right side portions 31, and therefore the partition member 34 are formed with a relatively steep slope has the following significance.
For example, when the cool air rises from the lower surface side of the basket 30, a part of the cool air may hit the wire 35 constituting the partition member 34 and escape to the outside following the inclination. At this time, the looser the gradient of the partition member 34, the greater the amount of cold air hitting the wire 35 and escaping. Therefore, in the present application, the partition member 34 has a steep slope to ensure the holding power of the regenerator A. Thus, the amount of cold air escaped is suppressed, that is, the amount of cold air flowing into the cold air passage S is increased.
Further, when the regenerator A is sandwiched between the partition members 34 on both sides, if the partition member 34 has a gentle gradient, the inner deep portion of the corner portion is sandwiched, but the partition member 34 as in this embodiment. When is steep, it is only to pinch a relatively shallow part of the corner. Thereby, the resistance at the time of taking out the cool storage agent A is reduced.

In the freezing chamber 12, a shelf network 60 is attached over a total of four stages, two stages on the upper side and the lower side.
Similar to the basket 30, the shelf network 60 is formed by assembling a plurality of metal wires such as steel wires. Specifically, as shown in FIG. 12, a rectangular outer frame 61 that is slightly smaller than the flat section of the freezing chamber 12 is provided. Between the left and right frames 61L and 61R of the outer frame 61, as will be described in detail later, three reinforcing bars 63 are passed on the same plane and fixed by welding. On the upper surface of the outer frame 32 to which the reinforcing bar 63 is assembled, a number of shelf bars 64 facing in the depth direction are placed side by side at predetermined intervals in the horizontal width direction and fixed by welding.

  Further, a stopper 65 capable of abutting the lower positions of the front and rear end surface portions 45 of the basket 30 is provided on the upper surface that enters the front side of the predetermined dimension from the rear frame 61D. What actually hits the stopper 65 is the frame 32F or 32R on the back side of the outer frame 32 constituting the left and right side surface portions 31. The stopper 65 is formed in a short gate shape over the entire width of the shelf network 60, and a mounting portion 66 formed by bending the lower ends of both leg portions to the back side is positioned at the back side of the left and right frames 61L and 61R. Is fixed by welding. The shelf network 60 is similarly coated with a resin coat.

On the other hand, shelf pillars 26 are attached to four places on the wall of the freezing chamber 12, for example, the left and right ends of the back wall 12A and the positions near the entrances of the left and right side walls 12B. Although not shown in detail in the shelf column 26, a large number of attachment holes for attaching the shelf receivers 27 are formed at a constant pitch.
Then, as shown in FIG. 13, the shelf net 60 is placed in a state in which the shelf receiver 27 is attached to each shelf column 26 at the same height, and both the left and right ends of the frame 61 </ b> D on the back side in the outer frame 32, The shelf net 60 is supported in a horizontal posture by placing the front end portions of the frames 61L and 61R on the corresponding shelf receivers 27 and hooking them.

The basket 30 is pushed from the front side and placed on the shelf network 60 supported as described above, and the pushing is stopped when the end surface portion 45 on the back side of the basket 30 hits the stopper 65, This position is the normal placement position of the basket 30. As described above, the handles 50 provided on the front and back end face portions 45 of the basket 30 are formed so as to open outward. However, as shown in FIG. 15, the basket 30 is stopped at the normal placement position. As far as it is concerned, the handle 50 on the back side is set to stay in front of the back wall 12A of the freezing chamber 12.
Further, the arrangement positions of the three horizontal bars 41 in the shelf network 60 are 4 from the front side of the basket 30 as shown in FIG. 13 when the basket 30 is pushed to the normal placement as described above. The seventh, eleventh, and eleventh regenerators A are provided at positions corresponding to the positions immediately below the storage area 38 respectively.

Then, the effect | action of this embodiment is demonstrated.
In the freezing chamber 12, a shelf network 60 is attached over a total of four stages, two stages on the upper side and the lower side.
On the other hand, the basket 30 is stacked up and down as shown in FIG. 16 before use. When the upper basket 30 is inserted into the lower basket 30 from above, the bottom portion of the upper basket 30 enters, and the lower horizontal bars 48 of both end surface portions 45 are arranged on the end surface portion 45 of the lower basket 30. The upper horizontal bar 46 is received by being hooked by the inwardly bent portions 47 at both ends. As a result, the baskets 30 are sequentially stacked while fitting a size of approximately 1/3 of the total height. As a result, the storage space is saved by stacking on a low profile.

When freezing the cold storage agent A, the stacked baskets 30 are separated, and the cold storage agent A is sequentially stored in the storage area 38 of the basket 30 as shown in FIG. 8 on a work table (not shown), for example. . As described above, since each regenerator A is stored in a state where the partition member 34 is inserted between the regenerators A, a predetermined gap is provided between the regenerators A as shown in FIGS. That is, the cold air passage S is secured.
In this way, two baskets 30 storing the regenerator A are placed on each shelf network 60 in the freezing chamber 12 on the left and right through the doorway 15 where the heat insulating door 17 is opened.

More specifically, each basket 30 is carried to the entrance / exit 15 in a posture in which the length direction is directed back and forth while grasping the handles 50 on both sides with both hands or supporting the bottom with one hand. In this case, the front and rear directions may be opposite. Moreover, since the handle 50 is formed in the outward opening and the handle part 52 is separated from the cold storage agent A at the end part, it is easy to hold.
As shown in FIG. 13, the rear end side of the basket 30 is placed on the front end portion in the right or left region of the shelf network 60, and subsequently pushed into the back. During this time, the protective cylinder 43 fitted to the horizontal bar 41 of the bottom surface portion 40 of the basket 30 is smoothly pushed in while rotating.
After that, when the end face portion 45 on the back side of the basket 30 hits the stopper 65, the pushing is stopped, and the basket 30 is left in that position and placed. At this time, as already described, the reinforcing rod 63 of the shelf network 60 is positioned directly below the cool storage agent A, that is, away from the cool air passage S between the cool storage agents A.

When all the baskets 30 are stored, the heat insulating door 17 is closed together. When the refrigeration apparatus and the internal fan 24 are driven from such a state, as shown in FIG. 2, the cold air generated in the cooler chamber 20 extends from the outlet 22 along the inner wall 12A of the freezing chamber 12. After being blown out and guided to the bottom of the freezing chamber 12 and partly guided below the second shelf network 60 from above, it rises through the basket 30 in which the regenerator A is stored, Inhaled from 21.
Here, the cold air rises through the cold air passages S formed between the regenerators A in each basket 30 including the opening 36 of the partition member 34. In particular, since the horizontal bar 41 of the bottom surface portion 40 of the basket 30 and the reinforcing bar 63 of the shelf network 60 are located away from the cold air passage S and do not interfere with the cold air flow, the flow amount varies for each cold air passage S. Hateful. Further, since the partition member 34 is provided with a steep slope, the amount of cool air escaped can be minimized as described above. Therefore, the cold air is circulated uniformly and with a large flow rate in each of the cold air passages S, and the entire cool storage agent A is frozen uniformly and efficiently.

When the freezing is completed, the cold storage agent A is taken out of the cabinet. For this purpose, after opening the heat insulating door 17, a hand is placed on the handle 50 on the near side, and the basket 30 is pulled out to the near side while sliding on the shelf network 60. Similarly, since the protective cylinder 43 is pulled out while rotating, it can be pulled out with a light force. For example, the basket 30 is placed on a work table, and, conversely, the upper end side of the cold storage agent A is grasped and pulled upward. Since a predetermined gap is secured between the cool storage agents A, the upper end side of the cool storage agent A is easy to grasp.
Further, since the cold storage agent A expands with the case when it is frozen, there is a possibility that the cold storage agent A is sandwiched between the partition members 34 on both sides. However, since the partition member 34 is formed to be elastically deformable, it is elastically deformed. However, the partition member 34 only sandwiches the shallow position of the lower corner of the regenerator A, and this is also effective in reducing the resistance at the time of extraction. Therefore, the regenerator A after freezing is easily taken out from the basket 30.

According to this embodiment, the following many advantages can be obtained.
Since the regenerator A is stored in the basket 30 with a gap (cold air passage S) opened in the basket 30 by the partition member 34 having the opening 36, the cold air blown into the freezing chamber 12 is stored in the opening 36 of the partition member 34. Is smoothly circulated through the cool air passages S between the regenerators A, so that all the regenerators A are frozen uniformly and efficiently. Since the shape of the basket 30 is merely changed, the basket 30 can be handled at a lower cost than the conventional one having a duct in the freezing chamber 12, and the volume of the freezing chamber 12 is not reduced.

Since the regenerator A expands in volume when it is frozen, there is a possibility that the regenerator A may be sandwiched by the partition members 34 from both sides. However, since the partition member 34 is elastically deformable, when the regenerator A is taken out, the partition member 34 Can be taken out while being elastically deformed, that is, with reduced resistance. As a result, it is possible to efficiently take out the regenerator A from the basket 30 after freezing.
Since the horizontal bar 41 constituting the bottom surface portion 40 of the basket 30 and the reinforcing bar 63 of the shelf network 60 on which the basket 30 is placed are arranged at positions avoiding the cold air passage S between the cold storage agents A, The circulation of the cold air in the cold air passage S is not hindered. Accordingly, the cold air can be more uniformly distributed over the entire cold air passage S.

  The left and right side surface portions 31 of the basket 30 are formed to open upward over the entire height, whereas the front and rear end surface portions 45 are formed so that only the upper side including the handle 50 is opened outward. Therefore, the baskets 30 can be stacked while fitting a part of the total height, and the overall length can be kept small. That is, it is possible to stack each basket 30 while keeping the storage capacity of the regenerator A to a minimum while keeping the back low when not in use, thereby saving storage space. Further, since the handle 50 is opened to the outside, a large gap can be secured between the handle portion 52 and the regenerator A stored in the end portion, the handle 50 can be easily grasped, and the basket 30 can be taken in and out. Easy to operate.

Since the protective cylinder 43 is rotatably fitted to the horizontal bar 41 constituting the bottom surface portion 40 of the basket 30, the basket 30 is taken in and out on the shelf network 60 while rotating the protective cylinder 43. Since the horizontal bar 41 of the basket 30 is not directly rubbed against the shelf network 60, it is difficult to be damaged such as the mutual resin coat being peeled off. Further, the sliding resistance is greatly reduced, and the basket 30 can be inserted and removed smoothly.
The basket 30 is formed by fixing a wire rod by welding. In particular, the partition member 34 needs to be positioned with high accuracy. Therefore, in the present embodiment, the side surface unit 31X, the bottom surface unit 40X, and the end surface unit 45X are separately formed, and then the units 31X, 40X, and 45X are integrated. In particular, since the side surface portion 31 including the partition member 34 can be assembled on a small dedicated jig and integrated by welding, the basket 30 in which the partition member 34 is positioned with high accuracy can be manufactured.
