  FIG. 2 is a diagram illustrating a state in which the humidity adjusting device 50 is attached to the floor surface. That is, it is a figure which shows the operation state of the ship control panel humidity adjustment system which concerns on this Embodiment.

  As shown in FIG. 2, the control panel 60 is placed on the upper surface (first main surface) side of the floor surface 70 at a predetermined place in the ship. There are a plurality of control panels 60 installed in the ship. In the control panel 60, a plurality of electrical components are arranged to control the electrical system of the ship.

  A space that allows a person to pass through is formed below the floor surface 70 in the ship, and a humidity adjusting device 50 is attached to the lower surface (second main surface) of the floor surface 70. Here, the humidity adjusting device 50 is attached to the lower surface side of the floor surface 70 at a position corresponding to the bottom surface of the control panel 60. That is, in the state where the control panel 60 is installed on the upper surface of the floor surface 70 and the humidity adjusting device 50 is attached to the lower surface of the floor surface 70, the bottom surface of the control panel 60 and the humidity adjustment are sandwiched between the floor surface 70. The mounting surface 9 of the device 50 faces.

  In addition, in a state where the control panel 60 is installed on the upper surface of the floor surface 70 and the humidity adjusting device 50 is attached to the lower surface of the floor surface 70, the control panel 60 and the humidity adjusting device 50 are connected to each other. A ventilation hole (not shown in FIG. 2) is provided. For example, the bottom surface of the control panel 60, the floor surface 70, and the mounting surface 9 of the humidity adjusting device 50 are each in a mesh shape or the like, and in a state where the humidity adjusting device 50 and the control panel 60 are disposed on the floor surface 70, An air passage connecting the inside of the control panel 60 and the inside of the humidity adjusting device 50 is formed through the surface 70.

  Next, the operation of the marine control panel humidity adjustment system according to the present embodiment will be described.

  When the ship is sailing on the sea, the humidity in the control panel 60 is adjusted using an air conditioner or the like installed in the ship. Therefore, during the navigation of the ship, the humidity adjusting device 50 according to the present invention is not attached to the lower surface of the floor surface 70.

  The ship enters the dock and removes the electrical equipment (electrical equipment) from each place on the ship in order to overhaul the electrical equipment (electrical equipment) on the ship. From the end of overhaul, etc., each electric equipment (electric equipment) etc. is installed in the original place (or new installation place) in the line. And the confirmation test operation | work of each electric equipment (electric equipment) etc. is performed during the said casket. Here, as described above, the air conditioner is returned to the shipboard just before the preparation for navigation is completed, and the electrical equipment (electrical equipment) etc. is checked without the air conditioner being installed for a long period of time. Test work needs to be done.

  Therefore, as shown in FIG. 2, a humidity adjusting device 50 is attached to the lower surface of the floor surface 70 in the ship being docked corresponding to each control panel 60. Here, the humidity adjusting device 50 may be provided corresponding to all the control panels 60 arranged in the ship, but the humidity adjusting device 50 corresponding to the specific control panel 60 depending on the use environment. May be provided.

  For example, it is assumed that an environment in which the humidity inside the ship is increased is known in advance, and there is a control panel 60 installed in the environment. In that case, the humidity adjusting device 50 may be attached only to the lower surface of the floor surface 70 on which the control panel 60 is installed. There are various environments in which the humidity increases. For example, as shown in FIG. 3, if a pipe 75 through which cooling water passes is arranged below the floor surface 70 where the control panel 60 is installed, During the confirmation test operation, the cooling water flows in the pipe 75, and the cold air generated by the flow of the cooling water adversely affects the control panel 60 above the pipe 75 due to an increase in humidity.

  As described above, the humidity adjusting device 50 is attached to the floor surface 70 below the control panel 60 by bringing the mounting surface 9 of the humidity adjusting device 50 into contact with the lower surface of the floor surface 70 and using the fixing member 9. Install. Then, the power plug 7 is inserted into an electric supply source near the installation position of the humidity adjusting device 50.

  Next, the humidity adjustment operation in the control panel 60 by the humidity adjusting device 50 will be described with reference to FIGS.

  The power supply unit 4 that receives power supply from the power plug 7 transmits electricity necessary for the operation to the heater 1, the fan 2, and the humidity control unit 3. The heater 1 performs heating. Further, the fan 2 sends the air heated by the heater 1 to the inside of the control panel 60 through the communication vent hole. The humidity control unit 3 is preset with a set humidity range. In the following description, as an example, it is assumed that the set humidity range is 60% to 65%.

  On the other hand, although not shown in FIG. 2 etc., a hygrometer is disposed in the control panel 60. The humidity in the control panel 60 is constantly measured and detected by the hygrometer. Although not shown in FIGS. 1 and 2 and the like, the detection result measured by the hygrometer is transmitted to the humidity control unit 3 in the humidity adjusting device 50 via the communication medium.

  The operation of the humidity adjusting device 50 is started. Here, it is assumed that the heater 1 and the fan 2 are in an OFF state. And the humidity control part 3 starts the process which compares the detection result (humidity value detected within the control panel 60) transmitted from the hygrometer with the preset humidity range. The comparison process is performed each time the humidity adjustment apparatus 50 is operating and a detection result is transmitted from the hygrometer.

  If the detection result is less than the upper limit of the set humidity range (as described above, 65% in the example in the present specification), the humidity controller 3 maintains the heater 1 and the fan 2 in the OFF state. And the control with respect to the fan 2 is not performed (refer FIG. 4).

  On the other hand, if the detection result is equal to or higher than the upper limit of the set humidity range (as described above, 65% in the example in the present specification), the humidity control unit 3 switches the heater 1 and the fan 2 from the OFF state to the ON state. Therefore, control for the heater 1 and the fan 2 is executed (see FIG. 4). Then, under the control of the humidity controller 3, the heater 1 starts a heating operation, and the fan 2 starts a blowing process.

  The air (dry air) in the humidity adjusting device 50 heated by the heater 1 is sent into the control panel 60 through the communication vent. In the present invention, the configuration of the fan 2 can be omitted, but the arrangement of the fan 2 allows the air (dry air) heated by the heater 1 to be more efficiently put into the control panel 60. It becomes possible to send in.

  Now, after the operation of the humidity adjusting device 50 is started, once the heater 1 and the fan 2 are switched to the ON state, the humidity control unit 3 performs the following operation.

  That is, if the detection result is larger than the lower limit of the set humidity range (as described above, 60% in the example in the present specification), the humidity control unit 3 maintains the ON state of the heater 1 and the fan 2. 1 and the fan 2 are not controlled (see FIG. 4).

  On the other hand, if the detection result is equal to or lower than the lower limit of the set humidity range (as described above, 60% in the example in the present specification), the humidity control unit 3 switches the heater 1 and the fan 2 from the ON state to the OFF state. Therefore, control for the heater 1 and the fan 2 is executed (see FIG. 4). Then, under the control of the humidity control unit 3, the heater 1 stops the heating operation, and the fan 2 stops the blowing process.

  Thereafter, as shown in FIG. 4, the humidity control unit 3 performs the above-described ON-OFF control of the heater 1 and the fan 2 so that the detection result is within the set humidity range. That is, when the detection result reaches the upper limit of the set humidity range, the humidity control unit 3 switches the heater 1 and the fan 2 to the ON state, and when the detection result becomes the lower limit of the set humidity range, the humidity control unit 3 1 and fan 2 are switched to the OFF state.

  During the navigation of the ship, the humidity of the control panel 60 is adjusted by an air conditioner such as an air conditioner. Therefore, the humidity control unit 3 is removed from the floor 70 during the navigation of the ship. Thereby, the space formed under the floor surface 70 can be made larger. That is, a large space below the floor surface 70 can be secured.

  As described above, the marine control panel humidity adjustment system according to the present embodiment includes the humidity adjustment device 50 that can be detached from the lower surface of the floor surface 70 on which the control panel 60 is installed. Then, when the ship is in the berth, the humidity adjusting device 50 is attached to the lower surface of the floor surface 70 and is operated corresponding to the desired control panel 60. Here, in the present invention, in the state where the humidity adjusting device 50 is attached to the floor surface 70, a communication vent hole that connects the inside of the control panel 60 and the inside of the humidity adjusting device 50 is formed.

  As described above, the marine control panel humidity adjustment system according to the present embodiment can adjust the humidity in the control panel 60 to a desired value by using the humidity adjustment device 50 and through the communication vent. Become. Therefore, since the insulation protection in the control panel 60 is possible, the electrical performance of the electrical components in the control panel 60 disposed in the ship is ensured even in an environment where the air conditioner or the like cannot be used while the ship is entering the ship. Can be prevented (that is, insulation protection of the electrical component can be secured).

  Further, in the marine control panel humidity adjustment system according to the present embodiment, the humidity adjustment device 50 includes the fan 2 that positively sends the air heated by the heater 1 into the control panel 60. The fan 2 is ON / OFF-controlled based on the detection result of the hygrometer and a predetermined set humidity range.

  Further, the configuration of the humidity adjusting device 50 is simple and can be assembled using only general-purpose parts. Therefore, the cost of the marine control panel humidity adjustment system according to the present embodiment can be reduced. In addition, since the humidity adjusting device 50 is of a size that can be carried, the humidity adjusting device 50 can be easily attached to and detached from the floor surface 70, and work labor and time can be reduced. .

  Therefore, the air heated by the heater 1 in the humidity adjusting device 50 can be efficiently blown into the control panel 60 through the communication vent hole. Therefore, it becomes possible to realize the humidity reduction in the control panel 60 earlier.

  Moreover, it is desirable that no hole be formed in the bottom surface of the humidity adjusting device 50 (the surface of the humidity adjusting device 50 facing the mounting surface 9). Thereby, for example, even when the piping 75 through which the cooling water flows is provided below the control panel 60, the cold air generated from the piping 75 is blocked by the bottom surface of the humidity adjusting device 50, and the humidity adjusting device 50 Can be prevented from entering the control panel 60 side existing above.

  In order to more completely prevent the cold air generated from the pipe 75 from entering the control panel 60, the bottom surface of the humidity adjusting device 50 is larger than the bottom surface of the control panel 60 as shown in FIG. It is desirable to be. As described above, the bottom surface of the humidity adjusting device 50 can completely cover the bottom surface of the control panel 60 from the lower side of the floor surface 70, and more completely prevent the cold air generated from the pipe 75 from entering the control panel 60. can do.

  In the above description, the ON / OFF control of the heater 1 and the ON / OFF control of the fan 2 are linked. That is, when the heater 1 is in the ON state, the fan 2 is also in the ON state, and when the heater 1 is in the OFF state, the fan 2 is also in the OFF state. However, while the humidity adjusting device 50 is in operation, the fan 2 may always be in the ON state regardless of the ON / OFF state of the heater 1.
