The device section 3 includes a power supply section for driving the dehumidification unit 5 and a switch section for controlling the operation of the dehumidification unit 5 .

The device section 3 embeds the dehumidifying unit 5 substantially in the center. The dehumidification unit 5 has a ventilation part 6 on the upper surface side. The ventilation part 6 allows the dehumidification unit 5 and the storage room 2 to communicate with each other. In the present embodiment, the ventilation section 6 is configured by a through hole penetrating the upper surface of the dehumidification unit 5 .

The ventilation section 6 includes a first ventilation section 6a (6) that takes in the air in the storage room 2 into the dehumidification unit 5, and a second ventilation section 6b (6) that releases the air in the dehumidification unit 5 to the storage room 2. Prepare.

The dehumidifying unit 5 includes a fan 14 driven by electric power as described later. When the fan 14 is driven, the air inside the storage room 2 is sucked through the first ventilation section 6a (6). The air sucked from the first ventilation section 6a (6) is absorbed by the desiccant contained in the dehumidifying unit 5, and the humidity is adjusted to be lower than before the moisture absorption.

The air absorbed by the desiccant is discharged into the storage room 2 through the second ventilation section 6b (6) as the fan 14 rotates. The dehumidification unit 5 takes in the air in the storage room 2 of the desiccator 1, adjusts it to low humidity with a desiccant, and then discharges it into the storage room 2. - 特許庁This makes it possible to keep the air in the storage room 2 at a low humidity.

FIG. 2 is an enlarged view showing an example of how the dehumidifying unit 5 is mounted according to this embodiment. The device section 3 has an area in which the dehumidifying unit 5 can be stored. The device section 3 has a through hole at a position corresponding to the ventilation section 6 .

The dehumidifying unit 5 is arranged in a region formed within the device section 3 . In the illustrated example, the dehumidifying unit 5 further comprises a container 12 containing a desiccant. The storage unit 12 is configured such that the desiccant can be replaced. The dehumidification unit 5 includes a housing 10 that accommodates the storage portion 12 and the like, and a top plate 11 that shields the upper surface of the housing 10 .

The top plate 11 of the dehumidification unit 5 is fixed to the device section 3 with screws or the like. The ventilation part 6 is a through hole provided through the top plate 11 . The ventilation part 6 allows the inside of the storage room 2 and the dehumidification unit 5 to communicate with each other, thereby allowing mutual air circulation. As will be described later, the ventilation section 6 is configured to be switchable between an open state and a closed state by the control section 20 .

The device section 3 has a through hole at a position corresponding to the ventilation section 6 . When the ventilation part 6 is controlled to be open, air is released from the dehumidification unit 5 into the storage room 2 through the ventilation part 6 and the through hole.

The storage section 12 is arranged detachably from the dehumidification unit 5 . As an example, the accommodation portion 12 is accommodated in the dehumidification unit 5 through an opening provided in the top plate 11 . The housing portion 12 may be engaged with the top plate 11 by screws or the like.

FIG. 3 is a diagram showing an example of the configuration of the dehumidification unit 5 in this embodiment. The dehumidifying unit 5 includes a housing 10 that accommodates the accommodating portion 12 and the like, and a top plate 11 that shields the upper surface of the housing 10 .

The dehumidification unit 5 includes a ventilation section 6, a dehumidification section 8 communicating with the outside of the desiccator 1, a storage section 12, and a fan 14 (not shown). The dehumidifying unit 5 may further include a heater 15 (not shown) that heats the housing portion 12 .

In the present embodiment, the ventilation section 6 includes a first ventilation section 6a (6) for sucking air in the storage room 2 and a second ventilation section 6b (6) for discharging air in the dehumidifying unit 5 into the storage room 2. ).

By driving the fan 14, the air in the storage room 2 is sucked into the housing 10 through the first ventilation portion 6a (6). The inhaled air is dehumidified by the desiccant in the container 12 arranged inside the housing 10 .

In this embodiment, the dampening section 8 is formed on the bottom surface of the housing 10 . The dehumidification part 8 is a through hole that allows the dehumidification unit 5 and the outside of the desiccator 1 to communicate with each other. The dehumidification section 8 is controlled by the control section 20 so as to be switchable between an open state and a closed state, and discharges air containing moisture from the dehumidification unit 5 to the outside of the desiccator 1 .

In this embodiment, the desiccator 8 includes a first dehumidifier 8 a ( 8 ) that sucks air from outside the desiccator 1 into the dehumidification unit 5 and discharges the air in the desiccator 5 to the outside of the desiccator 1 . It is composed of the second moisture discharging section 8b (8).

The control unit 20 controls either the ventilation unit 6 or the dehumidifying unit 8 so that it can be opened exclusively. The control unit 20 can control the ventilation unit 6 to be in an open state and the moisture exhausting unit 8 to be in a closed state. Further, the control unit 20 can control the moisture discharging unit 8 to be in an open state and the ventilation unit 6 to be in a closed state.

In a state in which the ventilation section 6 is opened by the control section 20 and the storage room 2 and the dehumidification unit 5 communicate with each other through the ventilation section 6, the air in the storage room 2 is sucked into the dehumidification unit 5, or the air inside the dehumidification unit 5 is Air can be vented into the storage room 2 . In this state, the desiccator 1 and the dehumidifying unit 5 are not communicated with each other because the desiccator 8 is closed.

On the other hand, the control unit 20 opens the dehumidifying unit 8 to allow communication between the dehumidifying unit 5 and the outside of the desiccator 1 . Air can flow into the dehumidification unit 5 . In such a state, the storage room 2 and the dehumidification unit 5 are not communicated with each other because the ventilation section 6 is closed.

By selectively opening either the ventilation section 6 or the moisture discharging section 8 by the control section 20, a situation in which both the ventilation section 6 and the moisture discharging section 8 are in an open state does not occur. Therefore, the storage room 2, the dehumidification unit 5, and the outside of the desiccator 1 are not connected in series, and the air outside the desiccator 1 cannot flow into the storage room 2 via the dehumidification unit 5. The occurrence can be well suppressed. This makes it possible to keep the air in the storage room 2 at a low humidity.

FIG. 4 is a timing chart showing an example of control modes of the ventilation section 6 and the dehumidification section 8 by the control section 20 in this embodiment. The horizontal axis of FIG. 4 indicates the passage of time, and the vertical axis indicates the control states of the ventilation section 6, the dehumidifying section 8, the heater 15, and the fan 14. In FIG.

The control unit 20 controls the ventilation unit 6 and the dehumidifying unit 8 to either an open state or a closed state at predetermined time intervals. The control unit 20 controls one of the ventilation unit 6 and the dehumidifying unit 8 to be open, and then controls the other to be closed. That is, the control unit 20 selectively opens either the ventilation unit 6 or the moisture exhausting unit 8 .

In the illustrated example, when the desiccator 1 is powered on at timing t1, the control unit 20 drives the fan 14, and the fan 14 is controlled to be continuously driven while power is being supplied to the desiccator 1. be done. The control unit 20 controls the fan 14 to be in a constantly driven state, so that air can be efficiently sucked and discharged.

When the power is turned on at timing t1, the control unit 20 controls the dehumidifying unit 8 to be in an open state and controls the ventilation unit 6 to be in a closed state. Then, the air flows out of the desiccator 1 into the dehumidifying unit 5, deprives the desiccant of moisture, and is discharged out of the desiccator 1 again. This restores the hygroscopic ability of the desiccant.

The controller 20 opens the dehumidifier 8 at timing t1 and controls the heater 15 from OFF to ON. When the heater 15 is turned on, heat is generated in the heater 15 and the housing portion 12 is heated. By heating the containing portion 12, evaporation of the moisture contained in the desiccant is promoted.

Thus, when the desiccator 1 is powered on, the controller 20 first opens the desiccator 8 to discharge the moisture of the desiccator out of the desiccator 1 . Then, after a predetermined period of time has passed, the moisture discharging section 8 is closed and the ventilation section 6 is opened. As a result, the dehumidifying section 8 is opened to increase the moisture absorbing ability of the desiccant, and then the ventilation section 6 is controlled to be open to dehumidify the air in the storage room 2, thereby efficiently performing the dehumidification work. It can be carried out.

When timing t2 arrives after a lapse of a predetermined time from timing t1, the control unit 20 controls the moisture discharging unit 8 from the open state to the closed state, and also controls the ventilation unit 6 from the closed state to the open state.

When the dehumidifying section 8 is controlled to be closed, the inflow of air from outside the desiccator 1 into the dehumidifying unit 5 is stopped. When the vent section 6 is controlled to be open, the air inside the storage room 2 is sucked into the dehumidifying unit 5 . The air sucked into the dehumidifying unit 5 is absorbed by the desiccant while passing through the storage section 12 . Air absorbed by the desiccant is released into the storage room 2 .

When the timing t2 arrives, the controller 20 controls the heater 15 from ON to OFF. When the heater 15 is controlled to be turned off and the generation of heat stops, the temperature of the housing portion 12 drops. In this way, evaporation of moisture from the desiccant can be satisfactorily suppressed, and air sucked from the storage room 2 can be satisfactorily absorbed by the desiccant. Further, by controlling the heater 15 to be OFF while the moisture discharging unit 8 is controlled to be in the closed state, the power consumption by the heater 15 can be reduced.

From timing t2 to timing t3, the control section 20 controls the ventilation section 6 to be in an open state and controls the moisture discharging section 8 to be in a closed state. When timing t3 arrives, the control unit 20 controls the ventilation unit 6 to be in the closed state and controls the moisture exhausting unit 8 to be in the open state. Also, at timing t3, the controller 20 controls the heater 15 from OFF to ON.

In the illustrated example, the control unit 20 sets the time for controlling the ventilation unit 6 to be open longer than the time for controlling the moisture discharging unit 8 to be open. Thereby, the air in the storage room 2 can be satisfactorily dehumidified.

FIG. 5 is a diagram showing an example of the configuration of the dehumidification unit 5 in this embodiment. The housing portion 12 is detachably engaged with the dehumidification unit 5 . The accommodating portion 12 is accommodated in the housing 10 through an opening provided in the top plate 11 .

The housing unit 12 has a housing, and the housing contains a desiccant. The housing portion 12 has a ventilation hole 12a on the side surface of the housing. This makes it easier for the air in the dehumidifying unit 5 to flow into the housing of the housing portion 12 .

The storage section 12 is arranged detachably from the dehumidification unit 5 . The upper surface of the housing portion 12 contacts the top plate 11 of the dehumidification unit 5 . The storage section 12 may be fixed to the dehumidifying unit 5 with screws or the like, but is configured to be detachable when the desiccant needs to be replaced.

The control unit 20 selectively controls opening of the ventilation unit 6 and the dehumidifying unit 8 . When the vent section 6 is controlled to be open, the moisture exhaust section 8 is controlled to be closed. On the other hand, when the moisture discharging section 8 is controlled to be open, the ventilation section 6 is controlled to be closed.

The control unit 20 switches between opening and closing of the ventilation unit 6 and the moisture exhaust unit 8 at predetermined time intervals. As an example, the control unit 20 switches between opening and closing of the ventilation unit 6 and the moisture exhaust unit 8 every 20 minutes or so. This makes it possible to continuously dehumidify the air in the storage room 2 while recovering the moisture absorbing ability of the desiccant stored in the storage section 12 .

FIG. 6 is a top view showing an example of the configuration of the dehumidification unit 5 in this embodiment. The housing 10 includes shielding walls 16 that divide the inside of the housing 10 in the height direction of the desiccator 1 . The shielding wall 16 blocks the space between the bottom surface of the housing 10 and the top plate 11, and divides the inside of the housing 10 into a first area 10a (10) and a second area 10b (10).

The dehumidification unit 5 has a fan 14 . The fan 14 is arranged through the shielding wall 16 . That is, the housing 10 is divided into a first area 10a (10) and a second area 10b (10) by the shielding wall 16, and the air in each area can be moved in the direction of the airflow generated by driving the fan 14. can.

In the illustrated example, the first ventilation section 6a (6) and the fan 14 are arranged in the first region 10a (10). On the other hand, the housing portion 12 and the second ventilation portion 6b (6) are arranged in the second region 10b (10).

When the fan 14 is driven, the pressure inside the first area 10a (10) is reduced, and the air inside the storage room 2 is sucked into the first area 10a (10) through the first ventilation section 6a (6). The sucked air passes through the fan 14 and moves from the first area 10a (10) to the second area 10b (10).

Driving the fan 14 increases the air pressure in the second region 10b (10). Therefore, the air that has moved from the first region 10a (10) passes through the housing portion 12 and is dehumidified by the desiccant. Then, the dehumidified air comes out of the storage section 12 and is discharged into the storage room 2 through the second ventilation section 6b (6). As a result, the air in the storage room 2 can be kept at a low humidity.

Next, the case where the control unit 20 closes the ventilation unit 6 and opens the moisture exhaust unit 8 will be described. A first moisture exhaust section 8a (8) is provided in the first region 10a (10). By driving the fan 14, the pressure in the first area 10a (10) is reduced, and the air outside the desiccator 1 is sucked into the first area 10a (10) from the first dehumidifying section 8a (8).

The air sucked into the first area 10a (10) moves from the first area 10a (10) to the second area 10b (10) as the fan 14 rotates. The air that has moved to the second region 10b (10) passes through the housing portion 12. As shown in FIG. At that time, the moisture is taken from the desiccant in the housing portion 12 .

Since the air pressure in the second region 10b (10) rises, the air containing moisture by depriving the desiccant of the desiccant exits from the storage unit 12 and exits the desiccator 1 from the second moisture exhausting unit 8b (8). Ejected. As a result, the moisture retained in the desiccant can be discharged to the outside of the desiccator 1, and the moisture absorbing ability of the desiccant can be recovered.

The second region 10 b ( 10 ) may be configured to communicate with the gas introduction section 40 . By communicating with the second area 10b (10), the gas introduction part 40 allows gas such as nitrogen gas to flow from the second ventilation part 6b (6) to the storage room 2 along the direction of the airflow generated by the rotation of the fan 14. can be released into

FIG. 7 is a side sectional view showing an example of the configuration of the dehumidifying unit 5 in this embodiment. The illustrated example shows an example of the configuration within the first region 10a (10) in the housing 10. As shown in FIG. A first ventilation section 6a (6), a fan 14, and a first moisture exhaust section 8a (8) are arranged in the first region 10a (10).

The first ventilation part 6 a ( 6 ) is formed through the top plate 11 . The first dampening part 8 a ( 8 ) is formed through the bottom surface of the housing 10 . The first ventilation section 6a (6) and the first moisture exhaust section 8a (8) are arranged substantially on the same line in the height direction.

A first stop valve 20a controlled by the control unit 20 is provided between the first vent section 6a (6) and the first moisture exhaust section 8a (8). The first stop valve 20 a is vertically movable based on a signal received from the controller 20 .

When opening the first ventilation section 6a (6) and closing the first moisture exhaust section 8a (8), the control section 20 moves the first stop valve 20a downward. The first stop valve 20a moves downward and stops at a position where it closes the first dampening section 8a (8). As a result, the control unit 20 opens the first ventilation part 6a (6) and controls the first moisture exhaust part 8a (8) to the closed state.

When opening the first moisture discharging section 8a (8) and closing the first ventilation section 6a (6), the control section 20 moves the first stop valve 20a upward. The first stop valve 20a moves upward and stops at a position that closes the first vent 6a (6). As a result, the control unit 20 opens the first moisture discharging unit 8a (8) and closes the first ventilation unit 6a (6).

The fan 14 is arranged through the shielding wall 16 . When the fan 14 rotates, the pressure inside the first region 10a (10) is reduced. Therefore, air is sucked through whichever of the first ventilation section 6a (6) and the first moisture exhaust section 8a (8) is open.

That is, when the first ventilation part 6a(6) is in the open state, the air in the storage room 2 is sucked into the first area 10a(10) through the first ventilation part 6a(6). On the other hand, when the first humidifying section 8a (8) is in the open state, the air outside the desiccator 1 is sucked from the first humidifying section 8a (8) into the first area 10a (10).

FIG. 8 is a side sectional view showing an example of the configuration of the dehumidifying unit 5 in this embodiment. FIG. 8 shows an example of the configuration of the second region 10b (10) in the housing 10. As shown in FIG. In the second area 10b (10), the second ventilation section 6b (6), the second moisture exhaust section 8b (8), the storage section 12, and the heater 15 are arranged, respectively.

The second ventilation part 6 b ( 6 ) is formed so as to penetrate the top plate 11 . The second dampening part 8b (8) is formed so as to penetrate through the bottom surface of the housing 10. As shown in FIG. The second ventilation section 6b (6) and the second moisture exhaust section 8b (8) are arranged substantially on the same line in the height direction.

A second stop valve 20b controlled by the control unit 20 is arranged between the second ventilation unit 6b (6) and the second moisture exhaust unit 8b (8). The second stop valve 20 b is vertically movable based on a signal from the control section 20 .

When opening the second ventilation section 6b (6) and closing the second moisture exhaust section 8b (8), the control section 20 moves the stop valve 20b downward. The second stop valve 20b moves downward and stops at a position where it closes the second dampening section 8b (8). As a result, the control unit 20 opens the second ventilation unit 6b (6) and controls the second moisture exhaust unit 8b (8) to be in the closed state.

When opening the second dampening section 8b(8) and closing the second ventilation section 6b(6), the control section 20 moves the second stop valve 20b upward. The second stop valve 20b moves upward and stops at a position that closes the second vent 6b (6). As a result, the control unit 20 opens the second moisture discharging unit 8b (8) and closes the second ventilation unit 6b (6).

The control unit 20 moves the first stop valve 20a and the second stop valve 20b in the same direction. That is, when both the first stop valve 20a and the second stop valve 20b are moved downward, the control section 20 closes the first damp discharge section 8a (8) and the second damp discharge section 8b (8), respectively. .

In this case, the first ventilation portion 6a (6) and the second ventilation portion 6b (6) are opened. Then, between the storage room 2 and the dehumidifying unit 5, the air can be moved through the first ventilation section 6a (6) and the second ventilation section 6b (6). As a result, the air containing moisture in the storage room 2 flows into the dehumidification unit 5, is dehumidified by the desiccant, and is delivered into the storage room 2. As shown in FIG.

On the other hand, when both the first stop valve 20a and the second stop valve 20b are moved upward, the control unit 20 closes the first ventilation part 6a (6) and the second ventilation part 6b (6), respectively. In this case, the first moisture exhaust section 8a (8) and the second moisture exhaust section 8b (8) are opened. Then, the dehumidifying unit 5 and the outside of the desiccator 1 are communicated with the first dehumidifying section 8a (8) and the second dehumidifying section 8b (8) to allow movement of air. As a result, air containing moisture from inside the dehumidifying unit 5 is discharged outside the desiccator 1 .

In the illustrated example, the heater 15 is arranged below the housing portion 12 . The control unit 20 controls the heater 15 from OFF to ON when controlling the first moisture exhausting unit 8a (8) and the second moisture exhausting unit 8b (8) to the open state. When the heater 15 is turned on and heat is generated, the heat is transferred to the housing portion 12 to accelerate the evaporation of moisture from the desiccant. By arranging the heater 15 below the housing portion 12 , the heat generated by the heater 15 increases and the housing portion 12 can be heated well.

In FIG. 8, the accommodating portion 12 is inserted from the top plate 11 into the second region 10b (10) and held. The accommodating part 12 is equipped with the ventilation hole 12a in the side surface. Air moved by the fan 14 from the first area 10a (10) enters the housing portion 12 through the air vent 12a.

The gas introduction part 40 (not shown) is configured to communicate with the second region 10b (10). When the gas is injected into the second area 10b (10), the gas introduction part 40 is discharged into the storage room 2 from the second ventilation part 6b (6).

FIG. 9 is a diagram showing an example of the configuration of the accommodation section 12 in this embodiment. The accommodation portion 12 includes a first side wall 12b and a second side wall 12c facing the first side wall 12b. Ventilation holes 12a are formed in the first side wall 12b and the second side wall 12c, respectively.

On the other hand, the third side wall 12d and the fourth side wall 12e adjacent to the first side wall 12b and the second side wall 12c are not formed with the vent hole 12a, and the third side wall 12d and the fourth side wall 12e are closed.

As will be described later, the accommodating portion 12 is arranged such that either one of the first side wall 12b and the second side wall 12c faces the fan 14. As shown in FIG. Then, the air moved by the rotation of the fan 14 flows into the housing portion 12 from the ventilation hole 12a in one of the first side wall 12b and the second side wall 12c facing the fan 14, and is arranged in the airflow direction. It flows out of the housing portion 12 through the ventilation hole 12a in the other side wall. That is, since the side walls having the ventilation holes 12 a are arranged along the direction of the air flow generated by the rotation of the fan 14 , the air can be efficiently passed through the housing portion 12 .

In the present embodiment, the housing portion 12 may further include a radiator plate 12f inside the housing portion 12 . The heat sink 12f is a plate-like member arranged inside the housing portion 12. As shown in FIG. The radiator plate 12f is made of a material capable of transmitting heat from the heater 15 arranged outside the housing portion 12. As shown in FIG. As an example, the heat sink 12f contains metal materials, such as aluminum and copper, for example.

The radiator plate 12 f may be in contact with the heater 15 . The contact of the radiator plate 12f with the heater 15 allows the heat of the heater 15 to be transmitted into the housing portion 12 more efficiently. In the illustrated example, the radiator plate 12f contacts the first side wall 12b and the second side wall 12c perpendicularly. As a result, the radiator plate 12f can satisfactorily increase the temperature inside the housing portion 12 without obstructing the passage of air through the housing portion 12. As shown in FIG.

The radiator plate 12f is arranged near the center inside the housing portion 12 . As a result, the heat of the heater 15 can be well transmitted to the central area in the housing portion 12, so that the evaporation of the moisture from the desiccant can be favorably promoted.

FIG. 10 is a partially enlarged view showing an example of the configuration of the dehumidifying unit 5 in this embodiment. FIG. 10 shows an example of a mode in which the housing portion 12 is arranged in the dehumidification unit 5. As shown in FIG. The housing portion 12 is inserted into the second region 10b (10) through an opening formed in the top plate 11. As shown in FIG.

The dehumidification unit 5 in this embodiment includes a support portion 25 that supports the storage portion 12 at a position corresponding to the storage portion 12 in the second region 10b (10). The support portion 25 abuts on the bottom surface of the housing portion 12 and the first side wall 12 b to the fourth side wall 12 e to support the housing portion 12 .

The support portion 25 is configured to open the first side wall 12b and the second side wall 12c. The support portion 25 sets the height of the side surface that abuts against the first side wall 12b and the second side wall 12c to be low. That is, the first side wall 12b and the second side wall 12c are configured to be open.

On the other hand, the supporting portion 25 has a high side surface that contacts the third side wall 12d and the fourth side wall 12e. As a result, the third side wall 12d and the fourth side wall 12e come into contact with the side surfaces of the support portion 25, thereby shielding the front.

Either the first side wall 12b or the second side wall 12c faces the fan 14 as described above. In the illustrated example, the second side wall 12 c is arranged to face the fan 14 . When the air is pushed forward by driving the fan 14, the air flows into the housing portion 12 through the ventilation holes 12a formed in the second side wall 12c.

The air that has flowed into the housing portion 12 is further pushed out and flows out of the housing portion 12 through the ventilation holes 12a formed in the opposed first side walls 12b. Ventilation holes 12a are formed in two opposing side surfaces of the accommodating portion 12, and one of these side surfaces is disposed at a position facing the fan 14, so that the air flows along the direction of the airflow generated by the fan 14. can pass through the housing portion 12 .

As described above, the vent hole 12a is not formed in the third side wall 12d and the fourth side wall 12e adjacent to the first side wall 12b and the second side wall 12c. By preventing the air from flowing out from the third side wall 12d and the fourth side wall 12e, the air stays in the housing portion 12 for a long time. This allows the air to be in contact with the desiccant for a long period of time inside the housing portion 12 .
