Description

[Technical field]

[0001] The present invention relates to a linked repository. [Background technology]

[0002] For example, Patent Document 1 discloses a storage cupboard for storing solvents, flammable liquids, etc. The storage cupboard disclosed in Patent Document 1 includes a shelf and an openable / closable door. The storage cupboard disclosed in Patent Document 1 also includes an exhaust device that can exhaust gas inside the shelf to the outside. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 9-502109 Summary of the Invention [Problem to be solved by the invention]

[0004] There are various types of storage cabinets. For example, in addition to storage cabinets with doors on the front as in Patent Document 1, there are also storage cabinets with drawers. For example, in the case of storage cabinets equipped with exhaust devices as in Patent Document 1, if these different types of storage cabinets are linked together to be used as one storage cabinet (linked storage cabinet), two exhaust devices will be provided for one linked storage cabinet. As a result, the linked storage cabinet will become larger.

[0005] On the other hand, it is also possible to connect two storage cabinets so that the exhaust port of one storage cabinet and the air intake port of the other storage cabinet overlap. In such a case, an exhaust device is installed only in the other storage cabinet, and the gas inside one storage cabinet can be exhausted through the other storage cabinet. However, it is necessary to align the positions of the exhaust port and the air intake port of the two storage cabinets. The positions of the exhaust port and the air intake port may depend on the type and shape of the storage cabinet. For this reason, when aligning the positions of the exhaust port and the air intake port as described above, the type and shape of each storage cabinet may be limited.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to increase the freedom of shape and type of each storage cabinet in a connected storage cabinet consisting of multiple storage cabinets. [Means for solving the problem]

[0007] The present invention employs the following configuration as a means for solving the above problems.

[0008] A first aspect of the present invention is a connected storage cabinet comprising a first storage cabinet, a second storage cabinet arranged on the first storage cabinet, and an exhaust device for exhausting air from the second storage cabinet, wherein the first storage cabinet comprises a support wall having a first air intake port formed therein, and a top wall supported from below by the support wall and having a first exhaust port formed therein, and the second storage cabinet comprises a bottom wall arranged opposite the top wall across a gap and having a second air intake port formed therein, and a surrounding wall that laterally surrounds and supports the bottom wall and laterally blocks the gap, the lower end of which is located below the bottom wall.

[0009] In a first aspect of the present invention, the second storage cabinet is disposed on the first storage cabinet. The bottom wall of the second storage cabinet is provided with a second air intake port and is located above the lower end of the surrounding wall. When such a second storage cabinet is placed on the first storage cabinet, the bottom wall of the second storage cabinet is disposed opposite the top wall of the first storage cabinet with a gap therebetween. Therefore, a space (hereinafter referred to as an intermediate space) surrounded by the surrounding wall is formed between the bottom wall of the second storage cabinet with the second air intake port provided and the top wall of the first storage cabinet with the first exhaust port provided.

[0010] The gas in the first storage cabinet is exhausted from the first exhaust port in the top wall into the intermediate space. The gas thus exhausted into the intermediate space flows into the interior of the second storage cabinet from the second air supply port of the second storage cabinet. The gas in the second storage cabinet is exhausted from the second storage cabinet by the exhaust device. That is, in the first aspect of the present invention, the gas flows in the order of the first air supply port of the first storage cabinet, the first exhaust port of the first storage cabinet, the intermediate space, the second air supply port of the second storage cabinet, and the exhaust device. Therefore, in the first aspect of the present invention, the gas in the first storage cabinet and the gas in the second storage cabinet can be exhausted by a single exhaust device.

[0011] Furthermore, since the first exhaust port of the first storage cabinet and the second air intake port of the second storage cabinet are connected via an intermediate space, even if the positions of the first exhaust port of the first storage cabinet and the second air intake port of the second storage cabinet are different when viewed from above, gas can be made to flow from the first exhaust port of the first storage cabinet to the second air intake port of the second storage cabinet. Therefore, according to the first aspect of the present invention, the shapes and types of the first storage cabinet and the second storage cabinet (each storage cabinet) do not depend on the positions of the exhaust port and the air intake port. Therefore, the first aspect of the present invention can improve the degree of freedom in the shape and type of each storage cabinet in a connected storage cabinet formed by connecting multiple storage cabinets.

[0012] A second aspect of the present invention employs a configuration in which, in the above-mentioned first aspect, a duct is provided, which is disposed in the gap and connects the first exhaust port and the second intake port.

[0013] According to the second aspect of the present invention, the flow path area of ​​the gas in the intermediate space is smaller than that in the case where no duct is provided. This reduces the volume of the space to be exhausted, and makes it possible to improve exhaust efficiency. Furthermore, even if the first storage cabinet and the second storage cabinet are connected with a slight relative misalignment in the front-rear or left-right directions, the duct can prevent gas from leaking from the intermediate space. Therefore, the first storage cabinet and the second storage cabinet can be easily positioned.

[0014] A third aspect of the present invention employs a configuration in which, in the above-mentioned first or second aspect, the first air intake is positioned rearward of the center of the first storage cabinet when viewed from above, the first air exhaust is positioned forward of the first air intake when viewed from above, the second air intake is positioned forward of the center of the second storage cabinet when viewed from above, and a second exhaust outlet connected to the exhaust device is formed in the ceiling wall of the second storage cabinet and positioned rearward of the second air intake when viewed from above.

[0015] According to the third aspect of the present invention, the first air intake port of the first storage is provided in a support wall that supports the first exhaust port from below, and is therefore located below the first exhaust port. Furthermore, the first air intake port is located behind the first exhaust port when viewed from above. Inside the first storage, gas flows from the first air intake port to the first exhaust port. The flow of gas inside the first storage is inclined with respect to the vertical direction so that the flow of gas goes from below to above, and from the rear to the front as it goes from below to above. By inclining the flow of gas inside the first storage with respect to the vertical direction, the flow path length of the gas in the first storage can be made longer than when it is in the vertical direction. As a result, it is possible to reduce the number of gas stagnation points inside the first storage.

[0016] According to the third aspect of the present invention, the second supply port of the second storage is provided in a bottom wall located below the top wall on which the second exhaust port is provided, and is therefore located below the second exhaust port. Furthermore, the second supply port is located forward of the second exhaust port when viewed from above. Inside the second storage, gas flows from the second supply port to the second exhaust port. The flow of gas inside the second storage is inclined with respect to the vertical direction so that the flow of gas goes from the bottom to the top, and from the front to the rear as it goes from the bottom to the top. By inclining the flow of gas inside the second storage with respect to the vertical direction, the flow path length of the gas in the second storage can be made longer than when it is in the vertical direction. As a result, it is possible to reduce the number of gas stagnation points inside the second storage.

[0017] In this way, according to the third aspect of the present invention, it is possible to reduce the number of locations where gas stagnates in the first and second storage cabinets. Therefore, for example, when containers containing volatile liquids are stored in the first and second storage cabinets, according to the third aspect of the present invention, it is possible to suppress volatile components from stagnation in the first and second storage cabinets.

[0018] A fourth aspect of the present invention is based on the third aspect and adopts a configuration in which the first storage cabinet is provided with a key unit located at the front end inside the top wall, the first exhaust port is positioned rearward of the rear end of the key unit when viewed from above, and the second air intake port is positioned forward of the first exhaust port when viewed from above.

[0019] According to the fourth aspect of the present invention, even if the first exhaust port is located at the rear of the key unit, the second air intake port is located forward of the first exhaust port. In other words, regardless of the position of the first exhaust port, the second air intake port can be located closer to the front of the second storage cabinet. According to the fourth aspect of the present invention, a long gas flow path length can be ensured in the second storage cabinet, regardless of the position of the first exhaust port. Therefore, it is possible to reduce the number of stagnant gas points inside the second storage cabinet. Effect of the Invention

[0020] According to the present invention, in a linked storage cabinet consisting of a plurality of linked storage cabinets, the flexibility in the shape and type of each storage cabinet can be improved. [Brief description of the drawings]

The surrounding wall 2f is formed in a C-shape when viewed from above, with the left wall 2f2 connected to the left end of the rear wall 2f1 and the right wall 2f3 connected to the right end of the rear wall 2f1.

[0030] A lower air intake port 21 is provided in the rear wall 2f1 of the surrounding wall 2f. In this embodiment, as shown in FIG. 2, the lower air intake port 21 is formed as a slit extending linearly in the vertical direction. A plurality of lower air intake ports 21 are provided and arranged in the left-right direction. However, the shape and arrangement direction of the lower air intake ports 21 are not particularly limited. Each lower air intake port 21 is an opening for taking in gas from the outside of the linked storage cabinet 1 into the storage space 20 of the lower storage cabinet 2, and is formed to penetrate the rear wall 2f1 in the front-rear direction.

[0031] Such a lower air supply port 21 is formed in the rear wall 2f1 located rearward of the center of the lower storage cabinet 2 when viewed from above. In other words, the lower air supply port 21 is disposed rearward of the center of the lower storage cabinet 2 when viewed from above.

[0032] The top wall 2b is a wall supported from below by the support wall 2a, and forms the ceiling of the lower storage cabinet 2. The top wall 2b is formed in a plate shape with the front and back surfaces facing up and down. The top wall 2b is formed with a lower exhaust port 22 (first exhaust port) for discharging gas from the lower storage cabinet 2.

[0033] The lower exhaust port 22 is disposed forward of the upper air supply port 31 when viewed from above.

The left key unit 2c can switch two of the four drawers 2d, which are disposed on the left side of the linked storage cabinet 1 of this embodiment, between an unlocked state and a locked state.

[0036] Each key unit 2c has a cylinder that is operated with a key and a switching mechanism that switches the state of the drawer 2d between an unlocked state and a locked state in response to the operation of the cylinder. The key unit 2c is positioned so that its front end coincides with the front surface of the top wall 2b, as shown in Figures 3 and 4.

[0037] The multiple drawers 2d are supported on the support wall 2a so as to be movable in the front-rear direction, and are installed so as to be removable from the storage space 20 of the lower storage cabinet 2. In this embodiment, four drawers 2d are provided. Two of the four are vertically long drawers 2d when viewed from the front, and are arranged adjacent to the right side of the linked storage cabinet 1 of this embodiment in the left-right direction. The remaining two of the four are wide drawers 2d when viewed from the front, and are arranged adjacent to the left side of the linked storage cabinet 1 of this embodiment in the up-down direction.

[0038] Each drawer 2d has, for example, a front wall portion that forms the front portion of the lower storage cabinet 2 when housed in the storage space 20, and a shelf portion that is housed in the storage space 20 and supports containers and the like. The shelf portion is preferably formed, for example, by punching metal or the like so that gas can pass through. This makes it possible to reduce the number of places in the storage space 20 where gas can stagnate.

[0039] The upper storage cabinet 3 is a storage cabinet located above the lower storage cabinet 2, and forms the upper part of the connected storage cabinet 1 of this embodiment. The upper storage cabinet 3 is supported from below by the lower storage cabinet 2. The upper storage cabinet 3 includes a support wall 3a, a top wall 3b, a shelf board 3c, and a door 3d.

[0040] The support wall 3a is a wall portion that supports the top wall 3b, and is formed with an upper air supply port 31 (second air supply port) for taking in gas into the upper storage 3. The support wall 3a includes a bottom wall 3e and a surrounding wall 3f. The bottom wall 3e forms the bottom of the upper storage 3, and is formed in a plate shape with the front and back surfaces facing in the up-down direction.

[0041] In this embodiment, the bottom wall 3e of the upper storage cabinet 3 is disposed opposite the top wall 2b of the lower storage cabinet 2 with a gap therebetween. That is, in this embodiment, as shown in FIG. 3, a space (intermediate space 40) is formed between the bottom wall 3e of the upper storage cabinet 3 and the top wall 2b of the lower storage cabinet 2.

[0042] In addition, an upper air supply port 31 is provided in the bottom wall 3e. In this embodiment, the upper air supply port 31 is formed to extend in the left-right direction, similar to the lower exhaust port 22 of the lower storage cabinet 2. Furthermore, a plurality of upper air supply ports 31 are formed and arranged in the left-right direction. However, the shape and arrangement direction of the upper air supply ports 31 are not particularly limited.

[0043] Each upper air supply port 31 is an opening for taking in gas from the intermediate space 40 into the upper storage 3, and is formed to penetrate the bottom wall 3e in the vertical direction. In this embodiment, the second air supply port is disposed forward of the center of the second storage when viewed from above, and disposed forward of the lower exhaust port 22 when viewed from above.

[0044] The surrounding wall 3f is disposed so as to surround the bottom wall 3e from the rear, left and right sides, and supports the bottom wall 3e. In this embodiment, the surrounding wall 3f has a rear wall 3f1 disposed on the rear side of the bottom wall 3e and facing the front-rear direction, a left wall 3f2 disposed on the left side of the bottom wall 3e and facing the front-rear direction, and a right wall 3f3 disposed on the right side of the bottom wall 3e and facing the front-rear direction. The surrounding wall 3f is formed in a C-shape when viewed from above, with the left wall 3f2 connected to the left end of the rear wall 3f1 and the right wall 3f3 connected to the right end of the rear wall 3f1.

[0045] 3 and 4, the surrounding wall 3f has a lower end 3f4 (the lower end of the rear wall 3f1, the lower end of the left wall 3f2, and the lower end of the right wall 3f3) located below the bottom wall 3e. The surrounding wall 3f has its lower end 3f4 abutted against the top wall 2b of the lower storage cabinet 2. Such surrounding wall 3f surrounds and supports the bottom wall 3e from the sides, and also blocks the intermediate space 40 (gap) from the sides.

[0046] The top wall 3b is a wall supported from below by the support wall 3a, and forms the ceiling of the upper storage 3. The top wall 3b is formed in a plate shape with the front and back surfaces facing up and down. The top wall 3b has an upper exhaust port 32 (second exhaust port) for discharging gas from the upper storage 3.

[0047] The upper exhaust port 32 is an opening connected to the abatement device 5, and is formed to penetrate the top wall 3b in the vertical direction. In this embodiment, the upper exhaust port 32 is disposed rearward of the upper air supply port 31 when viewed from above.

[0048] The shelf board 3c is disposed in the storage space 30 of the upper storage cabinet 3, and both the left and right ends are supported by the surrounding wall 3f. A plurality of shelves 3c are arranged in the vertical direction. A container or the like can be placed on each shelf board 3c. Each shelf board 3c is preferably formed, for example, by punching metal or the like so that gas can pass through. This makes it possible to reduce the number of places in the storage space 30 where gas can stagnate.

[0049] The door 3d forms the front of the upper storage cabinet 3 and is connected to the support wall 2a via a hinge. Such a door 3d is supported so as to be openable and closable. When the door 3d is opened, the storage space 30 is opened forward, and when the door 3d is closed, the storage space 30 is closed.

[0050] In this embodiment, the lower end of the door 3d is located below the bottom wall 3e so that the lower part can cover the intermediate space 40 from the front. Therefore, when the door 3d is opened, the storage space 30 is opened toward the front, and when the door 3d is closed, the storage space 30 is closed.

[0051] The duct 4 is disposed in the intermediate space 40, and connects the lower exhaust port 22 of the lower storage cabinet 2 and the upper air intake port 31 of the upper storage cabinet 3. The duct 4 abuts against the upper surface of the top wall 2b of the lower storage cabinet 2 and the lower surface of the bottom wall 3e of the upper storage cabinet 3, and is disposed so as to surround the lower exhaust port 22 and the upper air intake port 31 when viewed from the top-bottom direction.

[0052] FIG. 6 is a perspective view of the duct 4. As shown in this figure, the duct 4 has a frame portion 4a and a flange portion 4b. The frame portion 4a is an annular member formed so that a central opening penetrates in the vertical direction. The lower end of the frame portion 4a abuts against the upper surface of the top wall 2b of the lower storage cabinet 2. The upper end of the frame portion 4a abuts against the lower surface of the bottom wall 3e of the upper storage cabinet 3. The flange portion 4b is formed so as to protrude from the lower end of the frame portion 4a toward the radial outside of the frame portion 4a, and the lower surface abuts against the upper surface of the top wall 2b of the lower storage cabinet 2. The flange portion 4b is fastened to the upper surface of the top wall 2b of the lower storage cabinet 2, for example, by a bolt (not shown) or the like.

[0053] The detoxification device 5 is disposed above the upper storage cabinet 3 and is fixed to the upper surface of the top wall 2b of the upper storage cabinet 3. The detoxification device 5 is connected to the upper exhaust port 32 provided on the top wall 2b, and is an exhaust device that exhausts the gas inside the linked storage cabinet 1 from the upper exhaust port 32 to the outside of the linked storage cabinet 1. The detoxification device 5 has a function of treating some of the components of the internal gas of the linked storage cabinet 1. For example, the detoxification device 5 is equipped with a filter or the like that adsorbs some of the components of the internal gas of the linked storage cabinet 1. If it is not necessary to treat the internal gas of the linked storage cabinet 1, an exhaust device without a treatment function may be installed instead of the detoxification device 5.

[0054] In the linked storage cabinet 1 of this embodiment, when the abatement device 5 is operated, outside air passes through the lower air supply port 21 and is taken into the inside of the lower storage cabinet 2. The gas taken into the inside of the lower storage cabinet 2 from the lower air supply port 21 is exhausted from the lower exhaust port 22 to the intermediate space 40 through the storage space 20. The gas exhausted from the lower exhaust port 22 to the intermediate space 40 is guided to the duct 4 and taken into the inside of the upper storage cabinet 3 from the upper air supply port 31. The gas taken into the inside of the upper storage cabinet 3 from the upper air supply port 31 is supplied to the abatement device 5 from the upper exhaust port 32 through the storage space 30. The gas supplied to the abatement device 5 is treated by the abatement device 5 and then discharged to the outside of the linked storage cabinet 1.

[0055] The connected storage cabinet 1 of this embodiment includes a lower storage cabinet 2, an upper storage cabinet 3 arranged on the lower storage cabinet 2, and a decontamination device 5 that exhausts air from the upper storage cabinet 3. The lower storage cabinet 2 includes a support wall 2a and a top wall 2b. The support wall 2a is formed with a lower air supply port 21. The top wall 2b is supported from below by the support wall 2a, and is formed with a lower exhaust port 22. The upper storage cabinet 3 includes a bottom wall 3e and a surrounding wall 3f. The bottom wall 3e is disposed opposite the top wall 2b with a gap therebetween, and is formed with an upper air supply port 31. The surrounding wall 3f supports the bottom wall 3e by surrounding it from the side and closes the gap from the side, and the lower end 3f4 is located below the bottom wall 3e.

[0056] In the linked storage cabinet 1 of this embodiment, the upper storage cabinet 3 is disposed above the lower storage cabinet 2. The bottom wall 3e of the upper storage cabinet 3 is provided with an upper air intake port 31 and is located above the lower end 3f4 of the surrounding wall 3f. When the upper storage cabinet 3 is placed on the lower storage cabinet 2, the bottom wall 3e of the upper storage cabinet 3 is disposed opposite the top wall 2b of the lower storage cabinet 2 with a gap therebetween. Therefore, a space (intermediate space 40) surrounded by the surrounding wall 3f is formed between the bottom wall 3e provided with the upper air intake port 31 of the upper storage cabinet 3 and the top wall 2b provided with the lower exhaust port 22 of the lower storage cabinet 2.

[0057] The arrows in Fig. 3 and Fig. 4 indicate the main flow of gas. As shown in these figures, the gas in the lower storage 2 is exhausted from the lower exhaust port 22 of the top wall 2b to the intermediate space 40. The gas thus exhausted to the intermediate space 40 flows into the interior of the upper storage 3 from the upper air supply port 31 of the upper storage 3. The gas in the upper storage 3 is exhausted from the upper storage 3 by the detoxification device 5. That is, in the linked storage 1 of this embodiment, the gas flows in the order of the lower air supply port 21 of the lower storage 2, the lower exhaust port 22 of the lower storage 2, the intermediate space 40, the upper air supply port 31 of the upper storage 3, and the detoxification device 5. For this reason, the linked storage 1 of this embodiment can exhaust the gas from the lower storage 2 and the upper storage 3 with one detoxification device 5.

[0058] Furthermore, since the lower exhaust port 22 of the lower storage cabinet 2 and the upper air supply port 31 of the upper storage cabinet 3 are connected via the intermediate space 40, even if the positions of the lower exhaust port 22 of the lower storage cabinet 2 and the upper air supply port 31 of the upper storage cabinet 3 are different when viewed from above, gas can be made to flow from the lower exhaust port 22 of the lower storage cabinet 2 to the upper air supply port 31 of the upper storage cabinet 3. Therefore, according to the linked storage cabinet 1 of this embodiment, the shape and type of the lower storage cabinet 2 and the upper storage cabinet 3 (each storage cabinet) do not depend on the position of the exhaust port or air supply port. Therefore, the linked storage cabinet 1 of this embodiment can improve the degree of freedom in the shape and type of each storage cabinet.

[0059] The connected storage cabinet 1 of this embodiment also includes a duct 4 that connects the lower exhaust port 22 and the upper air supply port 31. According to the connected storage cabinet 1 of this embodiment, the flow path area of ​​the gas in the intermediate space 40 is smaller than when the duct 4 is not provided. This reduces the volume of the space to be exhausted, making it possible to improve exhaust efficiency. Furthermore, even if the lower storage cabinet 2 and the upper storage cabinet 3 are connected with a slight misalignment relative to each other in the front-rear and left-right directions, the duct 4 can prevent gas from leaking from the intermediate space 40. Therefore, the lower storage cabinet 2 and the upper storage cabinet 3 can be easily positioned.

[0060] In the connected storage cabinet 1 of this embodiment, the lower air intake port 21 is located behind the center of the lower storage cabinet 2 when viewed from above. The lower exhaust port 22 is located forward of the lower air intake port 21 when viewed from above. The upper air intake port 31 is located forward of the center of the upper storage cabinet 3 when viewed from above. The upper exhaust port 32 connected to the abatement device 5 is formed in the top wall 2b of the upper storage cabinet 3, and is located behind the upper air intake port 31 when viewed from above.

[0061] According to the linked storage cabinet 1 of this embodiment, the lower air intake port 21 of the lower storage cabinet 2 is provided in the support wall 2a that supports the lower exhaust port 22 from below, and is therefore located below the lower exhaust port 22. Furthermore, the lower air intake port 21 is located behind the lower exhaust port 22 when viewed from above. Inside the lower storage cabinet 2, gas flows from the lower air intake port 21 to the lower exhaust port 22. The flow of gas inside the lower storage cabinet 2 is inclined with respect to the vertical direction so that the flow of gas goes from the bottom to the top, and from the back to the front as it goes from the bottom to the top. By inclining the flow of gas inside the lower storage cabinet 2 with respect to the vertical direction, the flow path length of the gas in the lower storage cabinet 2 can be made longer than when it is in the vertical direction. As a result, it is possible to reduce the number of gas stagnation points inside the lower storage cabinet 2.

[0062] According to the linked storage 1 of this embodiment, the upper air supply port 31 of the upper storage 3 is provided in the bottom wall 3e located below the top wall 2b where the upper exhaust port 32 is provided, and is therefore located below the upper exhaust port 32. Furthermore, the upper air supply port 31 is located forward of the upper exhaust port 32 when viewed from above. Inside the upper storage 3, gas flows from the upper air supply port 31 to the upper exhaust port 32. The flow of gas inside the upper storage 3 is inclined with respect to the vertical direction so that it goes from the bottom to the top and from the front to the rear as it goes from the bottom to the top. By inclining the flow of gas inside the upper storage 3 with respect to the vertical direction, the length of the gas flow path in the upper storage 3 can be made longer than when it is in the vertical direction. As a result, it is possible to reduce the number of gas stagnation points inside the upper storage 3.

[0063] In this way, the linked storage cabinet 1 of this embodiment can reduce the number of locations where gas stagnates in the lower storage cabinet 2 and the upper storage cabinet 3. For this reason, for example, when containers containing volatile liquids are stored in the lower storage cabinet 2 and the upper storage cabinet 3, the linked storage cabinet 1 of this embodiment can prevent volatile components from stagnation in the lower storage cabinet 2 and the upper storage cabinet 3.

[0064] In the linked storage cabinet 1 of this embodiment, the lower storage cabinet 2 includes a key unit 2c located at the front end inside the top wall 2b. The lower exhaust port 22 is located behind the rear end of the key unit 2c when viewed from above. The upper air supply port 31 is located forward of the lower exhaust port 22 when viewed from above.

[0065] According to the linked storage cabinet 1 of this embodiment, even when the lower exhaust port 22 is located behind the key unit 2c, the upper air supply port 31 is located forward of the lower exhaust port 22. In other words, regardless of the position of the lower exhaust port 22, the upper air supply port 31 can be located closer to the front of the upper storage cabinet 3. According to the linked storage cabinet 1 of this embodiment, a long gas flow path length in the upper storage cabinet 3 can be ensured regardless of the position of the lower exhaust port 22. Therefore, it is possible to reduce the number of places where gas stagnates inside the upper storage cabinet 3.

[0066] Although the preferred embodiment of the present invention has been described above with reference to the attached drawings, it goes without saying that the present invention is not limited to the above embodiment. The shapes and combinations of the components shown in the above embodiment are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.

[0067] For example, in the above embodiment, a configuration has been described in which the lower storage cabinet 2 is a storage cabinet equipped with a drawer 2d, and the upper storage cabinet 3 is a storage cabinet equipped with a door 3d. However, the present invention is not limited to this. For example, the lower storage cabinet 2 may be a storage cabinet equipped with a door, or another type of storage cabinet. Also, the upper storage cabinet 3 may be a storage cabinet equipped with a drawer, or another type of storage cabinet.

[0068] In the above embodiment, a configuration including a lower storage cabinet 2 and an upper storage cabinet 3, that is, a configuration including two storage cabinets, has been described. However, the present invention is not limited to this. For example, it is also possible to configure a linked storage cabinet in which three or more storage cabinets are stacked.
