Description

  The present invention relates to a humidity control structure of a storage cabinet having a humidity control function in a cabinet body.

Conventionally, storing wet items such as umbrellas, shoes, clothes, tableware, etc. in storage cabinets with doors placed at the entrance or kitchen etc., the humidity inside the cabinet body of the storage cabinet rises, It becomes a problem to cause mold. In addition, if condensation occurs in the cabinet body, it will not dry easily, and high humidity will continue indefinitely.
Therefore, there is a storage cabinet provided with a humidity control panel and a dehumidifier in the cabinet body.

  However, if a humidity control panel is provided in the cabinet body, the humidity control panel containing a certain amount of moisture cannot be absorbed unless it is regenerated by drying the humidity control panel by opening the door as appropriate. Become. If the humidity is generated before the humidity control panel releases the absorbed moisture, the humidity control panel does not function, so that the humidity in the cabinet body increases and causes mold. In the case where the humidity control panel cannot be regenerated in this way, the moisture absorption function of the humidity control panel is likely to be lowered, and the frequency of replacing the humidity control panel is increased.

The following Patent Document 1 discloses a cabinet body provided with a dehumidifying device. The dehumidifying device described here heats the moisture absorbent by a heater when the moisture absorbent absorbs moisture, and regenerates the moisture absorbent. It is described that it has a playback function to achieve the above.
Further, in Patent Document 1 below, a pair of first intake ports and a first exhaust port are provided on one surface of the casing body, and a pair of second intake ports and a second exhaust port are provided on an adjacent surface of the surface. A dehumidifying device provided is described.
According to this, since the switching valve for opening and closing the pair of intake / exhaust ports is provided, the intake / exhaust ports that are open toward the interior are opened, the interior air is sucked in, and moisture is absorbed by the moisture absorbent. After absorbing moisture, the dried air can be exhausted into the cabinet. On the other hand, when drying and regenerating the hygroscopic agent after moisture absorption, open the intake / exhaust port that opens to the outside of the warehouse, heat the intake air outside with a heater, dry and regenerate the hygroscopic agent, and remove moisture. The contained air can be exhausted to the outside through the exhaust port. Therefore, it can be set as the dehumidification apparatus which does not need replacement | exchange of a hygroscopic agent over a long period of time.

Japanese Utility Model Publication No. 5-85426

However, in order to install such a dehumidifying device in the cabinet body (inside the cabinet), one of the pair of intake / exhaust ports must be installed so as to communicate with the opening communicating with the outside (outside the cabinet). , It takes time to install. Further, when the dehumidifying device is attached to the side plate of the cabinet body, the dehumidifying device is provided so as to protrude from the side plate.
Further, Patent Document 1 describes that a heater for heating the moisture absorbent is intermittently turned on / off using a timer, and a switching valve for opening / closing the intake / exhaust port is operated accordingly. Therefore, in this case, the switching valve operates to open and close the intake / exhaust port when a predetermined time elapses regardless of the humidity in the cabinet body.
That is, when the intake / exhaust port is opened / closed based on the time measured by the timer, the side communicating with the outside may be in an open state, although it is not necessary to dry the moisture absorbent. In addition, although it is necessary to absorb moisture in the cabinet body, the opening communicating with the cabinet body may be closed, and it is difficult to adjust and maintain the interior of the cabinet body at an optimum humidity.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a humidity control structure of a storage cabinet that can adjust and maintain the storage space in the cabinet body at an optimum humidity.

  In the humidity control structure of the storage cabinet according to the invention of claim 1, a humidity control space in which a humidity control panel is stored is formed in the interior of the cabinet body of the storage cabinet, A storage space formed in front of the humidity control space in the cabinet body and an inner opening that communicates with the humidity control space, and an outer opening that communicates with the humidity control space and the outside of the cabinet body. It is provided, It is comprised so that opening and closing of the said inner opening part and outer opening part can be switched freely.

  In the present invention, the humidity control panel may be provided inside the humidity control space and provided upright along the back plate of the cabinet body.

  In the present invention, the humidity control panel may constitute a part of a back plate of the cabinet body, and the humidity control space may be formed around the humidity control panel.

  In the present invention, a hygrometer may be provided in the storage space, outside the cabinet body, and in the humidity control space.

  In the present invention, an opening is formed in front of the cabinet body, the opening is closed by a door, and when the opening is closed by the door, the inside of the cabinet body is hermetically sealed. It may be a thing.

According to the humidity control structure of the storage cabinet according to the present invention, since the humidity control space in which the humidity control panel is stored is formed in the interior of the cabinet body of the storage cabinet, it may interfere with the storage space. Absent.
The humidity control space communicates between a storage space formed in front of the humidity control space in the cabinet body and an inward opening communicating with the humidity control space, and the humidity control space and the outside of the cabinet body. And an outer opening that is configured to freely switch between opening and closing of the inner opening and the outer opening.
According to this, for example, when it is desired to absorb moisture in the storage space in the cabinet body, if the inner opening is opened and the outer opening is closed, the moisture is taken into the humidity conditioning space, and the humidity control panel Moisture can be absorbed. On the other hand, after absorbing moisture in the storage space in the cabinet body, if the inner opening is closed and the outer opening is opened, the outside air is taken into the humidity control space and the humidity control panel can be dried. .
Therefore, it is possible to prevent the humidity control panel from containing too much moisture and making it impossible to absorb moisture, and while maintaining the humidity control performance of the humidity control panel for a long time, the storage space in the cabinet body is adjusted to the optimum humidity. Can be maintained.

  In the present invention, when the humidity control panel is installed in the humidity control space and is provided upright along the back plate of the cabinet body, the humidity control panel can be configured without taking up a large humidity control space. Therefore, the space for the humidity control space can be saved, and a large storage space in the cabinet body can be secured.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS.
The storage cabinet 1 includes a box-shaped cabinet main body 2 having an opening 24 formed in the front, and a humidity control space 3 formed in the cabinet main body 2 in which the humidity control panel 4 is stored.
At the front opening 24 (the left side in FIG. 1) of the cabinet body 2 is provided a door 10 that can be opened and closed by a hinge provided on one side. When the door 10 is closed, the door 10 is opened. The part 24 is blocked by the door 10. The surface of the door 10 that contacts the opening 24 is provided with an elastic packing 7. When the door 10 is closed, the packing 7 interposed between the opening 24 and the peripheral edge thereof is elastically deformed and its reaction force. Therefore, the cabinet body 2 can be sealed. The packing 7 may be provided not on the door 10 side but on the peripheral edge of the opening 24.

The cabinet body 2 of the storage cabinet 1 includes an upper plate 20 disposed on the top, side plates 21 disposed on the left and right sides, a back plate 22 disposed on the back side, and a bottom plate 23 disposed on the bottom. Is done.
It should be noted that a base ring may be provided in the lower region of the bottom plate 23.
A partition plate 11 that partitions the storage space 25 and the humidity control space 3 is provided in the back (rear) of the cabinet body 2, and the space formed between the partition plate 11 and the back plate 22 is the humidity control. It becomes space 3.
The humidity control panel 4 is provided in the humidity control space 3 and is provided upright along the back plate 22. At this time, the humidity control panel 4 is provided so as to have a space before and after it so that moisture can be absorbed or released efficiently.
According to this, since the thin plate-like humidity control panel 4 is provided upright along the back plate 22, the humidity control space 3 can be configured without being pushed out toward the storage space 25 side. Space saving of the humidity control space 3 can be achieved, and a large storage space 25 in the cabinet body 2 can be secured.
As the humidity control panel 4, a hygroscopic board using diatomaceous earth, silica gel or the like is used.
A front portion excluding the humidity control space 3 formed in the interior of the cabinet body 2 is a storage space 25 for storing storage items 6 such as umbrellas, shoes, clothes, and tableware. The configuration inside the cabinet body 2 is not limited to the illustrated example, but may be a drawer or a partition plate that partitions the space vertically.

An inner opening 30 communicating with the storage space 25 and the humidity control space 3 is formed in a rectangular shape above the partition plate 11. The inner opening 30 has an opening / closing plate that opens and closes the opening. (Not shown) is provided. The opening / closing mechanism of the opening / closing plate is not particularly limited, and may be, for example, a louver.
Above the back plate 22, an outer opening 31 communicating with the humidity control space 3 and the outside of the cabinet body 2 is formed in a rectangular shape at a position facing the inner opening 30. 31 is provided with an opening / closing plate (not shown) for opening and closing the opening. The opening / closing mechanism of the opening / closing plate is not particularly limited as in the case of the inner opening 31, and may be a louver, for example.

A net-like body may be attached to the inner opening 30 and the outer opening 31, and according to this, it is possible to prevent insects and dust from entering the cabinet body 2 including the humidity control space 3. .
It is desirable that the humidity control space 3 is also hermetically sealed so as not to be affected by outside air, and putty or the like is provided at a portion where air enters the cabinet body 2 through a gap (between the partition plate 11 and the cabinet body 2). The filler may be caulked.

A hygrometer 5 is provided in the storage space 25, outside the cabinet body 2, and in the humidity control space 3.
Below, the inside of the storage space 25 will be described as part A, the inside of the humidity control space 3 as part B, and the outside of the cabinet body 2 will be described as part C.
The position where the hygrometer 5 is provided is not limited to the illustrated example. However, in the case of part A, for example, the hygrometer 5 may be provided in a place where it is easy for the user to see and does not interfere with the storage of the storage items 6. preferable.
In addition, a display unit (not shown) made of a liquid crystal panel or the like may be provided on the door 10 or the like so that the user can check the humidity of each of the A part, the B part, and the C part from outside the storage cabinet 1 at a time. In particular, for the portion B, the hygrometer 5 is provided in the humidity control space 3 and is difficult to check. Therefore, when the display portion is provided, the confirmation becomes easy. Of course, when the outer opening 31 is in the open state, the hygrometer 5 in the B portion may be confirmed.

1A shows a state in which the inner opening 30 is opened and the outer opening 31 is closed, and shows a moisture absorption process and a humidity adjustment process in the storage space 25. FIG.
When the stored item 6 is stored in the storage space 25, moisture generated from the stored item 6 flows into the humidity control space 3 through the inner opening 30 and is absorbed by the humidity control panel 4. Is opened. Moisture flowing into the humidity control space 3 from the storage space 25 through the inner opening 30 is absorbed by the humidity control panel 4. Then, the moisture absorption by the humidity control panel 4 almost eliminates the generation of moisture from the stored items 6, and the storage space 25 can be led to low humidity. Moreover, since the cabinet body 2 has a sealed structure, even if the humidity outside the cabinet body 2 is high, a low humidity state can be maintained without being affected by outside air.

1B shows a state in which the inner opening 30 is closed and the outer opening 31 is opened, and the drying process of the humidity control panel 4 is shown.
When moisture is absorbed by the humidity control panel 4 and the humidity in the storage space 25 becomes low, the inner opening 30 is closed, and the outer opening 31 is opened so that the outside air can be taken in and the moisture can be released. To do. If the outer opening 31 is in an open state, the humidity control panel 4 is dried and absorbed by the humidity control panel 4 by the outside air that has flowed into the humidity control space 3 through the outer opening 31 without opening the door 10. The moisture can be released to the outside of the cabinet body 2 through the outer opening 31.
In the drawing, the arrows described in the inner opening 30 and the outer opening 31 indicate the flow of air.

  The timing when the state shown in FIG. 1 (a) or FIG. 1 (b) is set is determined manually by the user while checking the hygrometer 5 provided in each part (A part to C part). The opening / closing of the direction opening 31 may be switched, or as described later, the opening / closing may be automatically performed by the control unit 8 controlled based on the timer unit 80 and the opening / closing discrimination unit 81.

Next, an example of manually switching between opening and closing of the inner opening 30 and the outer opening 31 will be described with reference to FIG.
The hygrometer 5 of each part is checked, and when the humidity of the A part is high and the humidity of the B part is low, the inner opening 30 is opened and the outer opening 31 is opened regardless of whether the humidity of the C part is low or high. Is closed and moisture absorption and humidity adjustment of the A portion, that is, the storage space 25 are performed (state 1 and state 2).
At this time, when the humidity of the part C is low, the outer opening 31 may be opened to release the moisture to the outside of the cabinet body 2.
When the humidity of both the A part and the B part is high and the humidity of the C part is low, it is necessary to release the moisture of the A part and the B part, so that the inner opening 30 and the outer opening 31 are opened. (State 3).

When the humidity of part A is low and the humidity of part B is high, when the humidity of part C is low, the inner opening 30 is closed and the outer opening 31 is opened to dry the humidity control panel 4. (State 4).
When the humidity of the A part is low and the humidity of the B part is high and the humidity of the C part is high, the outer opening 31 is closed so that the A part and the B part can be maintained at a low humidity (state 5). ).
When the humidity of the A part and the B part is low, even if the humidity of the C part is low or high, both the inner opening 30 and the outer opening 31 are closed so that moisture from outside the cabinet body 2 does not enter, A sealed state is set (state 6, state 7).

  According to the above, the inner opening 30 and the outer opening 31 are appropriately viewed while the user looks at the hygrometer according to the place where the storage cabinet 1 is placed, the season, the land pattern, the contents 6 and the like. It is possible to switch between opening and closing. In addition, the humidity control panel 4 can be prevented from containing too much moisture and cannot absorb moisture, and the humidity control performance of the humidity control panel 4 can be maintained for a long time. It can be maintained. Further, if the packing 10 is provided on the door 10 and the cabinet body 2 can be hermetically sealed when the door 10 is closed, the structure is less likely to be affected by external humidity changes. Can do. Therefore, the inside of the storage space 25 can be adjusted and maintained at the optimum humidity more effectively without being affected by external humidity changes.

  Note that FIG. 2 is an example of switching between opening and closing, and is not limited to this, and the opening and closing may be performed based on a simpler guideline. For example, the humidity state is judged only from the heights of A part and B part. When the inner opening 30 is open, the outer opening 31 is closed, and when the outer opening 31 is open, the inner opening 30 is closed. Switching such as closing may be performed. In the case of such a configuration, a mechanism that interlocks the opening and closing mechanisms of the inner opening 30 and the outer opening 31 can be employed. At this time, in some cases, if the mechanism to be interlocked can be released, it is possible for the user to be easy to use.

Next, a modification of the first embodiment will be described with reference to FIG.
Portions common to the above-described embodiment are denoted by common reference numerals, and descriptions of configurations and effects of the common portions are omitted.
The modification described here is the same in the basic structure of the storage cabinet 1 in that the humidity control space 3 is formed in the interior of the cabinet body 2 and the humidity control panel 4 is internally provided. 30 and the opening and closing of the outer opening 31 is different in that automatic control by the control unit 8 is performed.

The storage cabinet 1 includes a timer unit 80 that measures the switching timing of the opening and closing of the inner opening 30 and the outer opening 31, and the inner opening 30 and the outer opening based on the time measured by the timer unit 80. The control part 8 which controls switching of opening and closing of 31 is provided.
According to this, a series of operation times of state 1, state 4 and state 1 shown in FIG. 2 are set by the timer unit 80, and switching between opening and closing of the inner opening 30 and the outer opening 31 is automatically performed. Can be.
The timer time of the timer unit 80 is set on the outer surface of the door 10 together with the above-mentioned display unit so that it can be freely set according to the storage items 6 and storage amount, the installation location of the storage cabinet 1, the season, the land pattern, etc. An operation unit (not shown) that can be used to operate settings and turn on / off the timer unit 80 may be provided.
Moreover, since the hygrometer 5 is provided in the A part to the C part, by checking and recording the humidity state by the hygrometer 5, it can be used as a reference for setting the timer time from the next time.
Furthermore, it is good also as a structure which can selectively set the mode which automatically controls switching of opening and closing of the inner opening part 30 and the outer opening part 31, and the mode which switches manually as mentioned above.

An example of control based on the time measured by the timer unit 80 will be described with reference to FIGS.
3, (a) shows a state (state 1) in which the inner opening 30 is opened and the outer opening 31 is closed, and shows a moisture absorption process and a humidity control process in the storage space 25. .
The user turns on the timer unit 80 in order to start the time measurement by the timer unit 80 when the wet storage item 6 is stored in the storage space 25.
At this time, the user may check the hygrometer 5 in each unit and set the set time of the timer unit 80. For example, the set time of the timer unit 80 is lengthened when storing the storage 6 containing a lot of moisture or during the rainy season.
When detecting the activation of the timer unit 80, the control unit 8 opens the inner opening 30 and closes the outer opening 31 until the set time elapses. Moisture generated from the stored item 6 flows into the humidity control space 3 through the inner opening 30, and the humidity flowing into the humidity control space 3 from the storage space 25 through the inner opening 30 is absorbed by the humidity control panel 4. Then, the moisture absorption by the humidity control panel 4 almost eliminates the generation of moisture from the stored items 6, and the storage space 25 can be led to low humidity. Moreover, since the cabinet body 2 has a sealed structure, even if the humidity outside the cabinet body 2 is high, a low humidity state can be maintained without being affected by outside air.

3, (b) shows a state (state 4) in which the inner opening 30 is closed and the outer opening 31 is opened, and the drying process of the humidity control panel 4 is shown.
The timer unit 80 measures the set time, and when the set time elapses, the control unit 8 closes the inner opening 30 and opens the outer opening 31 on the assumption that moisture has been absorbed by the humidity control panel 4. Thereby, the moisture control panel 4 is dried by the outside air taken in from the open outer opening 31 and the moisture absorbed by the humidity control panel 4 is released to the outside of the cabinet body 2 through the outer opening 31. .
According to the above, since the opening and closing of the inner opening 30 and the outer opening 31 are automatically controlled, there is no human error such as forgetting the switching timing of the opening and closing, which is convenient for the user. Can be good.
In the drawing, the arrows described in the inner opening 30 and the outer opening 31 indicate the flow of air. Alternatively, an open / close detection sensor may be provided on the door 10 to trigger the timer unit 80.

Next, still another modification of the first embodiment will be described with reference to FIG.
Portions common to the above-described embodiment are denoted by common reference numerals, and descriptions of configurations and effects of the common portions are omitted.
The basic structure of the storage cabinet 1 is also the same in the modified example described here, such as the humidity control space 3 formed in the interior of the cabinet body 2 and the humidity control panel 4 provided therein. Although the switching of the opening and closing of the inner opening 30 and the outer opening 31 is automatically controlled by the control unit 8 as in the above-described modified example, the determination result by the opening / closing determination unit 81 is not the timer unit 80. It differs in that it is controlled based on humidity detection control.

The storage cabinet 1 detects the measurement value by the hygrometer 5 measured in the A part to the C part, and determines an opening / closing discriminating part 81 that judges the switching timing of the inner opening 30 and the outer opening 31. Based on the determination result by the opening / closing determination unit 81, a control unit 8 that controls switching between opening and closing of the inner opening 30 and the outer opening 31 is provided.
The open / close discriminating unit 81 discriminates whether it is higher or lower than a preset threshold value from the measurement values obtained by the hygrometer 5 measured in the A part to the C part, and based on the result, the inner opening 30 and the outer opening It is determined whether any of 31 should be opened or closed. Then, the control unit 8 controls the opening / closing of the inner opening 30 and the outer opening 31 based on the determination result from the opening / closing determination unit 81. The program for determining opening / closing of the inner opening 30 and the outer opening 31 by the opening / closing determination unit 81 can be set as a condition, for example, as shown in FIG.

Also in this case, a configuration in which a mode for automatically controlling switching between opening and closing of the inner opening 30 and the outer opening 31 and a mode for manually switching may be selected and set.
According to the above, since the opening and closing of the inner opening 30 and the outer opening 31 are automatically controlled, there is no human error such as forgetting the switching timing of the opening and closing, which is convenient for the user. Can be good. Further, since the control is performed based on the actual measurement value by the hygrometer 5, the opening and closing of the inner opening 30 and the outer opening 31 are switched at an appropriate timing according to the humidity condition at that time. The inside of the storage space 25 can be adjusted and maintained at an optimum humidity.

(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIG.

The inner lid 12 and the outer lid 13 are provided so that a little space is formed between the front side and the rear side of the humidity control panel 4 so as not to block the humidity control panel 4. The inner lid body 12 and the outer lid body 3 are configured to move in the front-rear direction individually or in conjunction with each other.

The configurations of the inner lid body 12 and the outer lid body 13 are not limited to the illustrated examples. For example, the inner lid body 12 and the outer lid body 13 are approximately the same size as the back plate 22. By making the same or the same color, the unevenness between the inner cover 12 and the outer cover 13 and the back plate 22 does not bother and is the same as the back plate 22, so it has excellent design. Can be.
In the figure, reference numeral 14 denotes a partition plate which is interposed between the inner lid body 12 and the outer lid body 13 and forms the humidity control space 3, and is provided above and below the humidity control panel 4. Therefore, the humidity control panel 4 is surrounded by the inner lid body 12, the outer lid body 13, and the partition plate 14 in a state where the humidity conditioning space 3 is closed.

As shown in FIG. 5A, when the inner lid body 12 is moved forward, a gap is formed between the partition plate 14 provided on the upper and lower sides and the inner lid body 12, and this is the inner opening 30. It becomes.
On the other hand, as shown in FIG. 5B, when the outer lid body 13 is moved rearward, a gap is formed between the partition plate 14 provided on the upper and lower sides and the outer lid body 13, and this is the outer opening. Part 31.
The opening / closing mechanism of the opening / closing plate of the inner opening 30 and the outer opening 31 may be interlocked with opening / closing by the opening / closing plate, such that when one is open, the other is closed. A mechanism that can release the interlock may be used.
A net-like body may be attached to the inner opening 30 and the outer opening 31, and according to this, it is possible to prevent insects and dust from entering the cabinet body 2 including the humidity control space 3. .
It is desirable that the humidity control space 3 be sealed so as not to be affected by the outside air, and a packing (not shown) is provided at a portion where the partition plate 14, the inner lid body 12 and the outer lid body 13 abut. May be.

  The point that the hygrometer 5 is provided in the storage space 25, the outside of the cabinet body 2, and the humidity control space 3 is the same as that of the first embodiment. A display unit (not shown) made of a liquid crystal panel or the like may be provided on the door 10 or the like so that the user can check the humidity of each unit from outside the storage cabinet 1 at a time.

5A shows a state in which the inner opening 30 is opened and the outer opening 31 is closed, and shows a moisture absorption process and a humidity adjustment process in the storage space 25. FIG.
When the stored item 6 is stored in the storage space 25, moisture generated from the stored item 6 flows into the humidity control space 3 through the inner opening 30 and is absorbed by the humidity control panel 4. Is moved forward to open the inner opening 30. Moisture that has flowed from the storage space 25 into the humidity control space 3 through the inner opening 30 is absorbed by the humidity control panel 4 and the humidity of the storage space 25 is prevented from becoming high. Then, the moisture absorption by the humidity control panel 4 almost eliminates the generation of moisture from the stored items 6, and the storage space 25 can be led to low humidity. If the outer lid 13 and the partition plate 14 are closed in a sealed state after the humidity is low, the low humidity state can be maintained even if the humidity outside the cabinet body 2 is high. .

5B shows a state in which the inner opening 30 is closed and the outer opening 31 is opened, and the drying process of the humidity control panel 4 is shown.
When moisture is absorbed by the humidity control panel 4 and the humidity in the storage space 25 becomes low, the inner lid 12 is moved rearward to close the inner opening 30 to take in outside air and to release moisture. The outer lid 13 is moved rearward so that the outer opening 31 can be opened. The moisture that has been dried by the outside air that has flowed into the humidity control space 3 through the outer opening 31 and has been absorbed by the humidity control panel 4 is released to the outside of the cabinet body 2 through the outer opening 31.
In the drawing, the arrows described in the inner opening 30 and the outer opening 31 indicate the flow of air.

  5A or 5B, the user manually checks the hygrometer 5 provided in each part (A part to C part) and manually moves the inner opening 30 and the outside. The opening / closing of the direction opening 31 may be switched, and as described above, the opening / closing is performed by the control unit 8 controlled based on the timer unit 80 (see FIG. 3) and the opening / closing discrimination unit 81 (see FIG. 4). You may make it perform automatically.

This also prevents the humidity control panel 4 from containing too much moisture and makes it impossible to absorb moisture, and can maintain the humidity control performance of the humidity control panel 4 for a long time. Can be adjusted and maintained.
Moreover, since it can comprise, without taking up the humidity control space 3, space saving of the humidity control space 3 can be achieved, and the storage space 25 in the cabinet main body 2 can be ensured large.
Furthermore, since the entire surface of the outside of the humidity control panel 4 is easily exposed to the outside air, it is easy to dry and the moisture absorption efficiency can be improved.

In addition, although the single storage cabinet 1 was illustrated in the above embodiment, it is applicable also to the system cabinet comprised by two or more.
Further, the shape, size, and configuration of the storage cabinet 1, the cabinet body 2, the storage space 25, the humidity control space 3, the inner opening 30, the outer opening, and the like are not limited to the illustrated examples.
Furthermore, the storage cabinet 1 is not limited to the installation type, and may be a suspension construction type.
