Each of the 2B interiors 20A and 20B (hereinafter also simply referred to as the interior 20) is dehumidified.

  FIG. 4 is a schematic sectional view of the dehumidifying unit 23.

  As shown in the drawing, the dehumidifying unit 23 is disposed so as to block the openings 213A and 213B formed in the back plates 212A and 212B of the housings 21A and 21B, for example. Here, the dehumidifying unit 23 is arranged in the interior 20 so as to close the openings 213A and 213B from the inside 20 side, but in the outside 27 so as to close the openings 213A and 213B from the outside 27 side. You may arrange. The dehumidifying unit 23 includes at least one drying device 230, a fan 231, and a housing 232 that houses the drying device 230 and the fan 231.

  In the housing 232, internal air inlets 233 a and 233 b for taking the air B 1 in the internal chamber 20 into the housing 232 as an internal air vent connecting the interior of the housing 232 and the internal chamber 20, and air in the housing 232 In-house exhaust ports 234a and 234b for discharging B2 to the inside 20 are formed. In addition, as an outside vent for connecting the inside of the housing 232 and the outside 27, the outside air intakes 235 a and 235 b for taking in the air A 1 in the outside 27 into the housing 232 and the air A 2 in the housing 232 are stored. External exhaust ports 236a and 236b for discharging to the outside 27 are formed. The fan 231 is driven to forcibly circulate the air between the inside of the housing 232 and the inside 20 or the outside 27 through the vents 233a, 233b to 236a, 236b.

  The drying device 230 includes a spherical or pellet desiccant 237 filled in the drying device 230, and a desiccant heater 238 accommodated in the drying device 230 together with the desiccant 237. The drying device 230 dehumidifies the air taken into the housing 232 from the interior 20 by absorbing moisture with the desiccant 237. Also, the desiccant 237 is heated by the desiccant heater 238, whereby the moisture absorbed by the desiccant 237 is discharged from the inside of the housing 232 to the outside 27.

  The desiccant 237 is a desiccant that can be heated and regenerated, such as zeolite and silica gel, and the desiccant 237 in an amount determined according to the space in the cabinet 20 is a drying device so that the air in the cabinet 20 can be sufficiently dehumidified. 230 is filled.

The desiccant 237 dehumidifies the interior of the housing 232 and discharges moisture through the slit.

  The desiccant heater 238 heats the desiccant 237 filled in the drying device 230 under the control of the control panel 24 to discharge the water accumulated in the desiccant 237 and regenerate the drying capacity.

  Further, the dehumidifying unit 23 includes a shutter 239a that exclusively opens and closes the internal intake port 233a and the external intake port 235a, and a shutter 239b that exclusively opens and closes the internal exhaust port 234a and the external exhaust port 236a. , Is further provided.

  Returning to FIG. 3, the description will be continued. The control panel 24 includes a sensor IF unit 240, an operation panel IF unit 241, a first dehumidifying unit IF unit 242, a second dehumidifying unit IF unit 243, and a main control unit 244.

  The sensor IF unit 240 is an interface for connecting the main control unit 244 to the sensor 26. The operation panel IF unit 241 is an interface for connecting the main control unit 244 to the operation panel 25. The first dehumidifying unit IF unit 242 and the second dehumidifying unit IF unit 243 are interfaces for connecting the main control unit 244 to the first dehumidifying unit 23A and the second dehumidifying unit 23B, respectively.

  The main control unit 244 receives information such as the temperature, dew point temperature, and humidity of the inside 20B of the second humidity control cabinet 2B by the sensor 26 via the sensor IF unit 240. Then, information such as the temperature, dew point temperature, and humidity of the inside 20B of the second humidity controller 2B received from the sensor 26 is displayed on the operation panel 25 via the operation panel IF unit 241. In addition, the main control unit 244 receives a user instruction from the operation panel 25 via the operation panel IF unit 241. Then, in accordance with the user instruction received from the operation panel 25, the first dehumidifying unit 23A and the second dehumidifying unit 23B are controlled via the first dehumidifying unit IF unit 242 and the second dehumidifying unit IF unit 243, and the first dehumidifying unit 23B is controlled. The inside 20A of the warehouse 2A and the inside 20B of the second humidity control cabinet 2B are dehumidified.

  Specifically, the main control unit 244 controls the first dehumidifying unit 23A as follows. Necessary in a state where the interior of the housing 232 is opened only to the inside 20A (inside air inlet 233a: open, outside air inlet 235a: closed, inside air outlet 234a: open, outside air outlet 236a: closed) Accordingly, the first dehumidifying process for rotating the fan 231 and the state in which the interior of the housing 232 is opened only to the outside 27 for a certain time (for example, 1 hour) (inside air inlet 233a: closed, outside air inlet 235a: opened) First heating regeneration process of rotating the fan 231 as necessary while operating the desiccant heater 238 to heat the desiccant 237 with the internal exhaust port 234a: closed and the external exhaust port 236a: open) Alternatively. By the first dehumidifying process, the humid air B1 in the interior 20A is taken into the housing 232 and dehumidified by the desiccant 237 of the drying device 230 absorbing moisture, and then the dry air B2 is stored in the interior 20A. It is discharged and the interior 20A is dehumidified. Further, the air A1 outside the chamber 27 is taken into the housing 232 by the first heat regeneration process, and moisture accumulated from the desiccant 237 heated by the desiccant heater 238 is released, and then the moist air A2 And the desiccant 237 is dried.

  Further, the main control unit 244 specifically controls the second dehumidifying unit 23B as follows. Necessary in a state where the inside of the housing 232 is opened only to the inside 20B (inside air inlet 233a: open, outside air inlet 235a: closed, inside air outlet 234a: open, outside air outlet 236a: closed) In response to the second dehumidifying process for rotating the fan 231 and the inside of the housing 232 opened only for a certain time (for example, 1 hour) outside the chamber 27 (inside the chamber 20A of the first humidity chamber 2A) (inside chamber intake) Necessary while heating the desiccant 237 by operating the heater 238 for the desiccant with the mouth 233a: closed, the outside air inlet 235a: open, the inside air outlet 234a: closed, the outside air outlet 236a: open) In response, the second heat regeneration process for rotating the fan 231 is performed alternatively. By the second dehumidifying process, the humid air B1 in the interior 20B is taken into the housing 232 and dehumidified by the desiccant 237 of the drying device 230 absorbing moisture, and then the dry air B2 is stored in the interior 20B. It is discharged and the inside 20B is dehumidified. Further, air A1 outside the chamber 27 (inside the chamber 20A of the first humidity control chamber 2A) is taken into the housing 232 and accumulated from the desiccant 237 heated by the desiccant heater 238 by the second heat regeneration process. After the released moisture is discharged, it is discharged as moist air A2 outside the box 27 (inside the box 20A of the first humidity control box 2A), and the desiccant 237 is dried.

  Here, the main control unit 244 adjusts so that the execution timings of the first heating regeneration process and the second heating regeneration process do not overlap. For example, when a heating regeneration interval common to the first heating regeneration process and the second heating regeneration process is set by the user via the operation panel 25, the first heating regeneration process and the second heating regeneration process are performed for each heating regeneration interval. Are carried out alternately. Alternatively, when the heating regeneration interval is individually set for each of the first heating regeneration process and the second heating regeneration process from the user via the operation panel 25, the first heating regeneration process and the second heating regeneration process are performed respectively. Perform at every playback interval. And when the implementation timing of one of the first heating regeneration process and the second heating regeneration process arrives, if the other is being implemented or if a predetermined time (for example, 1 hour) has elapsed since the end of the other implementation, One of them is implemented after a predetermined time has elapsed since the end of the implementation.

  The intrusion prevention fence 3 blocks a gap between the second humidity chamber 2B and the wall surface of the interior 20A of the first humidity chamber 2A, so that the user can mistakenly store the stored item with the second humidity chamber 2B. It arrange | positions in the clearance gap between 20 A of wall surfaces of the inside of the 1st humidity chamber 2A. In addition, in order to efficiently dehumidify the inside 20A of the first humidity control chamber A including the front of the second humidity control chamber 2B by circulating the air around the second humidity control chamber 2B, Perforated metal is used for air permeability.

  The present inventor increased the number of dehumidifying units 23 to two in Comparative Example A and Comparative Example A in which the second humidity control chamber 2B was omitted from the storage 1 as a comparison target storage. The comparative example B which made the number the same number as the storage 1 was prepared, and the dew point temperature when the storage 1 and the comparative examples A and B were operated for a long time was measured.

  FIG. 5 is a diagram showing the measurement results of the dew point temperature when the storage 1 and the comparative examples A and B are operated for a long time (about 50 hours).

  Here, the graph 40 shows the dew point temperature in the cabinet 20B of the storage 1, the graph 41 shows the dew point humidity in the cabinet of Comparative Example A, and the graph 42 shows the dew point temperature in the cabinet of Comparative Example B, respectively. The test environment is the same (ambient temperature 25 degrees, ambient humidity 30 to 55% RH). Further, the heating regeneration interval of the dehumidifying unit 23 is set to 6 hours, and the storage 1 is subjected to the first heating regeneration processing (heating regeneration processing of the first dehumidifying unit 23A of the first humidity control chamber 2A) and the second heating regeneration processing (second The second dehumidifying unit 23B of the humidity control chamber 2B is alternately heated and regenerated for about 3 hours, and in Comparative Example B, the heating and regenerating processes of the two dehumidifying units 23 are alternately performed for about 3 hours. ing.

As shown in graph 41, the lowest reached dew point temperature of Comparative Example A was approximately −38.0 ° C. (water vapor amount: 0.165 g / m ³ ). In the graph 41, the dew point temperature periodically rises (reference numeral 410), which is due to the influence of the heat regeneration process performed every 6 hours. Moreover, as shown in the graph 42, the lowest reached dew point temperature of Comparative Example B was approximately −40.5 ° C. (water vapor amount 0.127 g / m ³ ). Also in the graph 42, the dew point temperature periodically rises due to the influence of the heat regeneration process performed every 3 hours (reference numeral 420). Moreover, as shown in the graph 40, the lowest reached dew point temperature of the storage 1 was approximately −68 ° C. (water vapor amount 0.00429 g / m ³ ). In the graph 40, a large increase (reference numeral 400) and a small increase (reference numeral 401) of the dew point temperature are alternately repeated. This is due to the influence of the first heat regeneration process (reference numeral 401) of the first humidity control chamber 2A and the second heat regeneration process (reference numeral 400) of the second humidity control chamber 2B, which are alternately performed every three hours. .

  As apparent from the graphs 40 to 42 shown in FIG. 5, although the number of dehumidifying units 23 in the storage 1 and the comparative example B is the same, the dew point temperature decrease amount of the comparative example B with respect to the comparative example A. Is −2.5 ° C. (reduced to approximately 77/100 in terms of water vapor), whereas the dew point temperature decrease of Comparative Example A in the storage 1 is −28 ° C. (approximately 100 minutes in terms of water vapor). 2.6), and the dehumidifying effect of the storage 1 is dramatically improved as compared with the comparative example B. This is considered to be due to the following reason. That is, in Comparative Example B, it is considered that outside air containing moisture enters through the packing portion of the door for accessing the inside of the cabinet, the attachment portion of the dehumidifying unit 23, and the like, and this affects the humidity of the inside 20 of the cabinet. It is done. Even in the storage 1, outside air enters the inside 20 </ b> B of the second humidity control chamber 2 </ b> B from the packing portion of the door 22 </ b> B of the second humidity control chamber 2 </ b> B, the attachment portion of the dehumidifying unit 23 </ b> B, and the like. Since dehumidification is performed in the inside 20A of the wet chamber 2A, the influence on the inside 2B of the second humidity chamber 2B is small. For this reason, it is thought that the dehumidification effect of the inside 20B was able to be improved dramatically.

  The embodiment of the present invention has been described above.

  According to the present embodiment, as a double structure system in which the second humidity control chamber 2B equipped with the second dehumidification unit 23B is installed in the inside 20A of the first humidity control cabinet 2A equipped with the first dehumidification unit 23A. As a result, outside air that enters the inside 20B of the second humidity chamber 2B from the packing portion of the door 22B of the second humidity chamber 2B, the attachment portion of the second dehumidifying unit 23B, etc., is inside the inside of the first humidity chamber 2A. It becomes the outside air dehumidified by 20A, and the influence on the inside 20B of the second humidity control cabinet 2B can be reduced. For this reason, the dehumidification effect of the inside 20B is drastically improved, and stored items such as secondary battery materials and organic EL sealing devices that require an ultra-low humidity environment with a dew point temperature of −50 ° C. or lower are stored. It is possible to provide a storage 1 suitable for the above.

  Moreover, in this Embodiment, it adjusts so that the implementation timing of the 1st heat regeneration process of 2 A of 1st humidity chambers and the 2nd heat regeneration process of the 2nd humidity chamber 2B may not overlap. Specifically, the first heating regeneration process and the second heating regeneration process are alternately performed at each heating regeneration interval. Alternatively, the first heating regeneration process and the second heating regeneration process are performed at each heating regeneration interval, and when one of the first heating regeneration process and the second heating regeneration process arrives, the other is If the predetermined time elapses from the end of the execution or the other execution, one is executed after the predetermined time elapses from the end of the other execution. By doing so, it is possible to disperse the increase in the dew point temperature due to the first heat regeneration process and the increase in the dew point temperature due to the second heat regeneration process, thereby suppressing the increase in the maximum dew point temperature.

  In addition, this invention is not limited to said embodiment, Many deformation | transformation are possible within the range of the summary.

  For example, in the above embodiment, punching metal is used for the intrusion prevention fence 3, but the present invention is not limited to this. The intrusion prevention fence 3 only needs to be capable of closing the gap between the second humidity chamber 2B and the wall surface of the interior 20A of the first humidity chamber 2A and having a vent or moisture permeability. For example, urethane or sponge may be used for the intrusion prevention fence 3. In this case, when the door 22A of the first humidity chamber 2A is opened, if it is a short time, outside air containing moisture passes through the intrusion prevention fence 3 and is located behind the interior 20A (second humidity chamber). In the state where the door 22A of the first humidity control cabinet 2A is closed, the air in the cabinet 20A passes through the intrusion prevention fence 3 over time and circulates. By doing this, the air in front of the inside 20A (in front of the second humidity chamber 2B) can be dehumidified.

  Further, instead of providing the intrusion prevention fence 3 with a vent or moisture permeability, at least a part of the intrusion prevention fence 3 may be opened and closed in conjunction with opening and closing of the door 22A of the first humidity control cabinet 2A.

  6 (A) and 6 (B) are diagrams for explaining a modified example 1A of the storage 1 and correspond to the AA schematic sectional view of FIG. 3. Here, FIG. 6 (A) shows a state in which the door 22A of the first humidity chamber 2A is closed, and FIG. 6 (B) shows a state in which the door 22A of the first humidity chamber 2A is opened. ing.

  In this modified example 1A, the intrusion prevention fence 3 is made of a plate material such as metal or plastic, and the intrusion prevention fence 3 is made up of the upper surface of the second humidity control chamber 2B and the interior 20A of the first humidity control chamber 2A. The first prevention fence 30 disposed in the gap with the ceiling, the second prevention disposed in the gap between the side surface and the lower surface of the second humidity control chamber 2B and the side surface and the bottom surface of the interior 20A of the first humidity control chamber 2A. It is divided into a fence (not shown). And the 2nd prevention fence is fixed and attached so that it may block in the crevice between the side and bottom of 2nd humidity control cabinet 2B, and the side and bottom of 20 A of interiors of 1st humidity control 2A, and the 1st prevention fence 30 is attached by a hinge 31 with a spring so that a gap between the upper surface of the second humidity control chamber 2B and the ceiling of the interior 20A of the first humidity control chamber 2A can be opened and closed. Here, the spring-equipped hinge 31 biases the first prevention fence 30 in a direction to close a gap between the upper surface of the second humidity control chamber 2B and the ceiling of the interior 20A of the first humidity control chamber 2A. Further, the holder 33 that holds the shaft 32 so as to be movable in the axial direction is in a closed state (a state in which a gap between the upper surface of the second humidity control chamber 2B and the ceiling of the interior 20A of the first humidity control chamber 2A is closed). The first prevention fence 30 is attached to the upper side of the opening of the casing 21A of the first humidity control cabinet 2A so that the shaft 32 is perpendicular to the first prevention fence 30.

  In the modified example 1A of the above configuration, as shown in FIG. 6A, in the state where the door 22A of the first humidity control chamber 2A is closed, the shaft 32 contacts the door 22A, and the first humidity control chamber 2A It is pushed into the cabinet 20A. Thereby, the shaft 32 contacts the first prevention fence 30 and the first prevention fence 30 is opened in a direction to open a gap between the upper surface of the second humidity control cabinet 2B and the ceiling of the interior 20A of the first humidity control cabinet 2A. Push up. As a result, the air around the second humidity chamber 2B circulates, and the inside 20A of the first humidity chamber A including the front of the second humidity chamber 2B can be efficiently dehumidified.

  As shown in FIG. 6B, in the state where the door 22A of the first humidity control chamber 2A is open, the first prevention fence 30 pushes back the shaft 32 by the restoring force of the spring-equipped hinge 31, and the second The gap between the upper surface of the humidity controller 2B and the ceiling of the interior 20A of the first humidity controller 2A is closed. As a result, it is possible to prevent the user from mistakenly placing the stored item in the gap between the second humidity control chamber 2B and the wall surface of the interior 20A of the first humidity control chamber 2A, and moisture is contained. It is possible to prevent outside air from entering the rear of the storage 20A (the rear of the second humidity control cabinet 2B).

  Moreover, in said embodiment, although the 2nd humidity chamber 2B of 1 unit | set is arrange | positioned in 20A of chambers of the 1st humidity chamber 2A, two or more units | sets in 20A of chambers of the 1st humidity chamber 2A The second humidity chamber 2B may be arranged. Moreover, you may arrange | position the 3rd humidity chamber provided with the structure similar to 2A of 1st humidity chambers and the 2nd humidity chamber 2B in the inside 20B of the 2nd humidity chamber 2B. In this case, it is preferable that the control panel 24 adjust the execution timing of the heat regeneration process so that the heat regeneration process of these humidity control chambers is not performed simultaneously.

  Further, in the above embodiment, the intrusion prevention fence 3 may be omitted. Further, the fan 231 of the dehumidifying unit 23 may be omitted. Further, the operation panel 25 may be omitted. When the operation panel 25 is omitted, the heating regeneration interval is set in the dehumidifying unit 23 in advance.

  In the above embodiment, the first dehumidifying unit 23A and the second dehumidifying unit 23B are controlled by a single control panel 24. However, the control panel is provided for each of the first dehumidifying unit 23A and the second dehumidifying unit 23B.
