However, in this dehumidifying apparatus, once the concentration of water vapor inside becomes high, the charged particles such as water vapor gas that has entered the inside or the inside of the body charged by the side of the body becomes charged. There is a problem that the dehumidifying effect becomes unstable due to particles such as water vapor gas, or the humidity on the side of the container to be dehumidified becomes stable at a relatively high humidity.

Further, the charged particles in the water vapor gas or the air are mainly electrolyte particles contained in seawater, and along with the electrolytic particles, dust is generated due to respiration of the container. When entering a small room, there was a problem that the moisture-permeable waterproof membrane was clogged extremely quickly, and the weather resistance was likely to be low. In addition, the conventional method has a drawback that it is difficult to reduce the size.

The present invention has been made in order to solve the above-mentioned conventional problems, and its object is to exist in the steam gas or the outside air charged by the electrical equipment housed in the container side. A dehumidifying device that can achieve a lower ultimate humidity on the dehumidified side (container side) without deteriorating the dehumidifying effect due to water vapor gas or other floating dust in the air that is easily charged, and can also provide a stable and continuous effect.

BEST MODE FOR CARRYING OUT THE INVENTION In order to describe the present invention in more detail, it will be described with reference to the accompanying drawings. First, the characteristics of the metallic grounding mesh (grounded conductive porous body) are presented. However, 3 mesh a
As shown in FIGS. 1 (a) and 1 (b), the setting positions of 1, a2 and a3 are the ventilation passages 2 of the tubular body 1 which are respectively arranged on the container 3 side and the grounding 4 is not set ( We performed two types of comparisons, one that was not grounded and the other that was set (grounded). The structure of each of the meshes a1, a2, and a3 used as the conductive porous body is the same 34 mesh × 32 mesh copper as in the comparative experiment (referred to as G2-0) of the drying rate of each mesh by thermal image analysis of the mesh. The line mesh was set in the same manner as in the vicinity of the three moisture-permeable waterproof membranes A, B, and C which were permeable. In addition, here, in the moisture-permeable waterproof membrane,
Product name Breathlon manufactured by Nitto Denko Corporation
2) was used. The moisture permeability is as follows by comparing the waterproof membranes (see Fig. 2). 1108-N40C <1100-C40A <1050-
E50B The air permeability is as follows (see FIG. 3). 1108-N40C <1100-C40A <1050-
E50B Here, in order to calculate the ratio with 1108-N40C having the lowest value of water vapor permeability as 1.0, and to compare with the fluctuation of air permeability centering on that value, the water vapor permeability and air permeability ( 1108-N40C is set to 1.0), and it is necessary to add this value to the air permeability.
Among the seven types, the above selections 1 to 3 are most convenient for forming the water vapor concentration gradient depending on the air permeability and the moisture permeability. It can also be selected instead of. Therefore, in Experiment G2-1 described later, was selected.

In order to confirm the relationship between the concentration gradient and the dehumidifying effect, BRN110 having a pore size of 1 μm was used as a target.
3-N40A was used. The reason why this sample was used was that it had the highest air permeability, and was aimed at simplifying the experimental design. Next is each waterproof membrane A, B, C
The first value of each is the moisture vapor transmission rate (g / m × m × da).
In y), the next value is the air permeability (sec / 100 cc). Membrane A ₁ BRN1103-N40A 380 23000 Membrane B ₁ BRN1103-N40A 380 23000 Membrane C ₁ BRN1103-N40A 380 23000 With the above characteristics and arrangement of membranes, the dehumidification effect does not appear prominently in the same configuration as in Experiment G2-1 described later. A moisturizing effect was recognized, but a dew condensation preventing effect was recognized. Therefore, the following combinations were selected. Membrane A BRN1050-P20B 4600 350 Membrane BRN1108-N40C 4500 400 Membrane B BRN1100-C40A 2000 1000 Membrane C BRN1050-E50B 250 18000

As the film A, BRN1108-N40C is used.
Can also be selected as a means of arranging these in place of BRN1050-P20B. The reason for these selections will be described later. In order to further enhance the dehumidifying capacity of the dehumidifying device constituted by the moisture permeable waterproof film constituting the ventilation passage, considering the volume of the container, for example, moisture permeability comparison (see FIG. 2).
If the vertical axis of the line graph in FIG. 2 is the Y axis and the horizontal axis is the X axis, the virtual straight line connecting the maximum value and the minimum value is X =
It is expressed by the formula −aY + b, but since the Y axis is just the type of product, that is, only the moisture-permeable waterproof membranes to be selected are arranged, b here is the value when the ideal Y = 0. Indicates. Further, the larger the difference between the minimum value or the maximum value of the line graph, that is, the larger a, the higher the dehumidifying effect. Furthermore, the dehumidifying effect is promoted when the maximum value and the minimum value are set to low values. That is, the value of b is reduced. On the contrary, when this mechanism is used as a moisturizing device, the membranes may be arranged from the container side to the outside air side so as to have the opposite inclination. The temperature gradient relationships in the cases of FIGS. 2, 3 and 4 are based on FIGS. 6 and 8. For this reason, when the temperature gradient relationship between the container side and the outside air side is the opposite relationship of FIGS. 6 and 8, of course, the arrangement on the container side outside air side of FIGS. The opposite relationship must be set up. Of course, when setting the opposite relationship, the water repellent side is directed to the outside air side and the nonwoven fabric side is directed to the container side. Since a temperature gradient between the chambers described below is generated, in the above arrangement of the membranes A ₁ , B ₁ and C ₁ , the change in moisture permeability and the change in air permeability were not set between the membranes. The effect of each chamber volume, which depends on the temperature gradient, appears strongly.

Further, since this device is a non-powered and non-powered dehumidifying device which mainly utilizes the temperature variation of the container, various specification changes can be considered depending on the region. Figure 4 shows
In addition to the inner and outer chambers, the number of chambers is further increased, and when the first to fourth membranes are set, the moisture permeability and the air permeability of the specific membrane to be used are shown as ratios. It is a schematic diagram of a graph and a graph of moisture permeability x air permeability. Thus, for example, in the case where the small chamber of the dehumidifying device as described in claims 1, 2, 3, 4, 5, 6, 7, 8, and 9 has four layers, for example, In an environment where the small chamber is very susceptible to humidification, one reverse gradient from the outermost chamber to the container side is used as the original dehumidification gradient (this gradient means that the moisture vapor permeability increases from the container side to the outside air side). In addition to the gradient of the thick line portion in the line graph of FIG. 2 by the arrangement in which the air permeability is set to decrease from the container side to the outside air side), as shown schematically in FIG. It is set at the outside air side opening, and the inflow of water vapor from the outside air into the container side is
It is possible to set the concentration gradient between the small chambers to be suppressed once, and to accelerate the discharge in the course of drying when the temperature rises, for example, during the sunshine time. Especially, at this time, the membrane set on the outside air side is Compared with the membrane set in the small chamber section set to the dehumidification gradient of No. 4, a membrane having a smaller gradient (in the same graph) and a smaller moisture permeability, and a gas permeability higher than that of the third membrane is used as the fourth membrane. If you choose a membrane,
Even when the humidity of the outside air is high for a long period of time,
Further, it is possible to suppress the humidity on the outside air side from moving to the container side, and moreover, it is possible to efficiently maintain the humidity inside the container at a low humidity.

FIG. 5 is an estimated view of the theory of the dehumidifying mechanism. The internal air moves to the outside air as the temperature of the container rises. On the contrary, since the air inside the container contracts as the outside air temperature decreases,
The outside air is breathed so that it passes through the ventilation path of this dehumidifier. Further, in each small chamber, a convection of a vaporous gas such as water vapor occurs. Even under such respiratory action,
Due to the difference in water vapor transmission rate and air permeability, there is a difference in the absolute amount of water vapor that can pass and the air flow rate in each small chamber, and this difference is forced from the first membrane to the third membrane in each small chamber. Therefore, the container side is dehumidified. Further, the metallic conductive porous body has a local cooling effect on the film adjacent to the second film, at the same time as removing the charged water vapor at this site, particularly when the second film is set on the container side. It also has the effect of transiently increasing local humidity, including the feature that it is easy to do, but it is difficult for charged water vapor to pass through when the container is inhaled, and it is passed by removing the charge when exhausting (inhaling). Since it is easy to perform, dehumidification is promoted by promoting discharge to the outside air side. Generally, a highly conductive porous body such as a metal mesh (for example, stainless steel, gold, platinum, copper) has low electrical resistance, while a synthetic resin mesh (for example, tetrafluoroethylene, Polyethylene, polyester, vinyl chloride, nylon, etc.) have high electrical resistance. Furthermore, it can be generally said that the high-conductivity mesh has higher thermal conductivity than the low-conductivity mesh. An exception to this is the carbon fiber mesh, which is highly conductive and inferior in thermal conductivity to the aforementioned metal mesh. Here, the static elimination function can be mentioned as a main element, but the thermal conductivity also has a large effect. That is, the metal mesh as described above contributes to the homogenization of the temperature and tends to act in the direction of cooling, while the mesh of the synthetic resin described above contributes to the homogenization as a heat retaining effect. . Therefore, the arrangement which does not contradict the temperature gradient sequence in FIGS. 6 and 8 has a significant positive effect on stabilization in consideration of the air permeability and the convection characteristics in the chamber.

It is more stable than the one without, and it can be seen from the comparison between FIG. 6 and FIG. 8 that the decreasing speed is faster. 4 Although the conductive grounded body is connected and grounded in a gradual and stable manner, the fluctuation of the external humidity is easily influenced by the fluctuation of the internal humidity. 7 and 9 (compared with 2 and 3), it takes time for the humidity inside the container to draw a descending curve, but the one in which the conductive porous body is connected and grounded is not used. Is about 50% and stable, while the humidity inside the container is about 37%, which is lower and stable. 5 On the other hand, considering the overall humidity fluctuation characteristics, as shown in Fig. 15 and Fig. 16, the one in which the conductive porous body is connected and grounded is more stable than the one in which it is not grounded. Moreover, by comparing FIG. 7 and FIG. 9, it can be seen that the decreasing rate shows a stable decrease. 6 The phenomena described in 2, 3, and 4 above are shown in FIGS.
In the comparison of the humidity difference between the outer chamber and the inner chamber, as shown in, the stable fluctuation amount is secured in the case where the conductive porous body is connected and grounded, and it is unstable in the case where it is not grounded. Moreover, it is supported by the fact that the fluctuation speed is extremely large.

Between the chambers, although weak, the movement of the charged water vapor occurred from the surface potential measurement results (FIGS. 24 and 25) of the moisture-permeable waterproof membrane, and the grounding of the conductive porous body was set. As a result, the electrically conductive porous body grounded eliminates the electrostatic charge of water vapor, which acts as an impeding factor in the moisture permeability and air permeability of the membrane, that is, charged air or charged water vapor and other charged properties during air movement between chambers. Since the movement of the gas is obstructed by its removal of static electricity, the metal mesh with articulated grounding can reach a significantly lower internal humidity of the container than the case without the setting. It is believed that Further, convection is generated in the chamber space under static pressure, and static elimination of the content gas in the chamber space is also performed in convection.

Further, it is known that water vapor in the air can be charged both anodicly and cathodically. Especially, due to regional differences or climate differences, these charges show various modes. It is also known that, as a phenomenon observed in the dielectric polarization, the charging property of water vapor depends on the electric field in which the water vapor exists, and the electric charge of the water vapor is transient.

Therefore, the static elimination effect of the conductive porous body is
It is also considered that the dehumidifying device is likely to be affected by a weak surface potential gradient or electrostatic characteristics generated by the constituent materials of the dehumidifying apparatus and the environment in which it is placed, or by the chargeability in the container.

Further, due to the metallic mesh, local stagnation of air and local humidity increase in the local portion occur, and at the same time, due to the convection phenomenon in the chamber, the flow velocity of water vapor with a shade is changed to the same mesh. It is also supported by the fact that the non-uniformity is observed on the same film during exhaust or intake in the thermal image measurement of the third film, which is also captured by the air and promotes exhaust on the outside air side.

Therefore, the potential gradient of the surface of the container and the constituent material of the dehumidifying apparatus and the environment in which it is placed, or the weak surface potential gradient generated by the chargeability (chargeability) in the container, or the electrostatic characteristics thereof, or its environment. Differences, for example, in areas with long sunshine hours, high humidity areas, dry areas such as desert areas, or in sea areas or high altitude areas, depending on the area difference, set the same mesh to the outside air side as appropriate. Or taking measures such as setting on the container side to promote static elimination measures in the entire chamber stroke and formation of temperature gradient near the membrane or in the chamber part so as not to obstruct discharge to the exhaust port. , The formation of local water vapor concentration gradient, the temperature of the kinetic energy source of water vapor particles in the chamber and mainly the chamber and Convection or in the gas section, the heat radiation phenomenon properly, can be adjusted for each region and adaptations.

From this fact, it is effective to utilize the mesh for the generation of the temperature gradient, and in particular, due to the static elimination action, the action due to the fact that the mesh is made of metal has high specific heat and high thermal conductivity. , Utilizing the acceleration of drying speed by grounding will be used here.

The use of a mesh is effective for adjusting the local humidity before and after the membrane, and a grounded mesh tends to be easier to dry and cool, and a non-grounded mesh tends to retain moisture and hard to cool.

On the contrary, for this reason, placing a substance which is easily charged with static electricity in the chamber promotes the moisturizing effect.

Therefore, by setting the conductive porous body to be insulated, or by setting a large amount of, for example, styrene foam having a high water absorbing property, which is easily charged, in the chamber, this device can be introduced into the outside air humidity. As a result, it can also be used as a moisturizer that can keep the internal humidity constant. That is, by setting a metal mesh that is not grounded and a substance that is easily charged and has a high heat retaining property (for example, styrene foam) in the chamber section, it can be easily converted into a moisturizing device.

In this test, a factor that impedes the flux due to the conductive porous body set close to the section between the chambers exerts an influence. In graph 2 and graph 4, the humidity inside the container, the inner chamber, the outer chamber. Since the intervals in the Y-axis direction on the outside air side are the same, when comparing the fluctuations in the diffusion rate, the influence of the convective volume in the chambers is proportional, and the humidity gradient between the chambers is less than 1 chamber volume. When it is set to 1, it is almost proportional to the inclination angle of the temperature gradient. Therefore, if this is applied and an efficient chamber volume design is performed, high efficiency can be expected.

In the experiment of this embodiment, the distance between the films is
They are evenly spaced. When the moisture vapor transmission rate and the air permeability of each membrane are arranged so as to decrease or increase from the outside air toward the container side, that is, the distance between each membrane as the boundary between each chamber or the volume of each chamber is According to the specifications, the distance setting or volume setting of each film forming the chamber, which is the cooling space of the air passing through each film, was considered to be convenient for generating a temperature gradient between each chamber,
In consideration of the effects of convection in the chamber, radiative cooling, or a conductive porous body, or convection control fins set inside the chamber, when the optimum distance setting or volume setting is set, this intention The general arrangement results in the generation of temperature gradients between the chambers. For example,
The cool air on the outside air side is set to have a higher air permeability from the outside air side toward the container side.Therefore, when the temperature inside the container is higher than the outside air temperature, the influence of the temperature on the container side should be less than that of the outside air. Therefore, the temperature of the chamber gradually decreases due to the heating on the container side in the chamber from the container side to the outside air side.

On the contrary, since the moisture permeability of the warm air on the outside air side is set to gradually decrease from the outside air side toward the container side, it becomes difficult for the water vapor particles to flow into the container side. . To lower the humidity, it is necessary to raise the temperature and reduce the amount of water vapor particles present per unit volume. It will be good.

As an application of the mesh, it is possible to control the convection phenomenon by providing a conductive material and a non-conductive material or a material having a low electric resistance value and a material having a high electric resistance value side by side. This is because the non-uniformity of the third film was observed during the thermal image observation of the third film at the time of exhaust or intake, and the temperature fluctuation occurred. In other words, the fact that the electrostatic potential fluctuates due to a slight temperature fluctuation indicates that the water vapor concentration of that part is fluctuating, and at the same time, the electrostatic potential of the same part also fluctuates due to the charging of the water vapor. Is also supported. In addition, this method can enable the design of the dehumidifying device that can effectively increase the dehumidifying effect without preparing many kinds of membranes when the specifications are changed due to regional differences. In addition, it can be a particularly important trump card for miniaturization and reduction of manufacturing cost.

In the case of the horizontal type of small box target machine, where the same conductive porous body, for example, conductive and non-conductive on the copper mesh surface, or a substance having a low electric resistance value and a substance having a high electric resistance value are provided side by side. (Circle-shaped film setting) is concentric or wave-shaped, and is a vertical type for large box target machines (in the case of multiple cylinder type)
Then, it is effective to configure the upper and lower components in a strip shape or to form the wave crest along the upper and lower portions.

Furthermore, when a mesh having an insulating property such as nylon and capable of being positively charged is used as a support for a moisture permeable waterproof membrane, it can be used as a supporting mesh on both sides of the waterproof membrane to achieve dehumidification. It is possible to prevent the dehumidifying effect of the device from being impaired, and to prevent dust from adhering to the moisture-permeable waterproof film.

[Embodiment 10] A portion of the electronic cooling element, which is set so as to penetrate the film and the conductive porous body, is electrically insulated from the conductive porous body on the cooling side or the heat generating side, respectively. Thus, the function of the conductive porous body can be prevented from being hindered by providing the structure for preventing the adverse effect of the leakage current from the electronic cooling / heating element. Further, on the cooling side and the non-cooling side (high temperature side) of the electronic cooling / heating element (Peltier element), leakage current is prevented through the convection control fins and the insulator so that heat transfer is efficiently transferred to each chamber space. Connecting.

Also, to prevent overwork,
Safety devices may be incorporated to limit the upper limit.

For example, a space closed in a cylinder, or
A temperature sensor or a humidity sensor may be set on the bottom of the box-side open side chamber or the outside air-side open side chamber, and the driving of the cooling / heating element may be automatically controlled by a microcomputer.

[Embodiment 11] In order to cause a temperature difference due to absorption of radiant heat, a coating having a different infrared absorption rate on the axial surface of the device is placed at a position where the required characteristics can be exhibited on the circumference. May be painted.

For example, the coating having a low absorptivity is applied to the vicinity of the apparatus flange, and the other coatings are applied or the coatings having a high absorption rate are applied.

FIG. 2 and FIG. 3 are comparison tables of waterproof membranes. FIG. 2 and FIG. 3 show that when several kinds of membranes are commercially available, the moisture permeability and the air permeability of a specific membrane are 1.0 in order to arrange them as described above. Is a graph showing the respective ratios (see Graph 1 above for a detailed example) and a graph of moisture permeability × air permeability. FIG. 2 shows a water vapor transmission rate comparison (each ratio when 1108-N40C is 1.0). Figure 3 shows the air permeability comparison (110
Representing each ratio when 8-N40C is 1.0.

In the case of the horizontal type (in the case of the sliced type arrangement),
When the volume of each chamber or the distance of each membrane is fixed, it may not be possible to immediately respond to the harsh natural environment in which the device and container are placed. Here, the items to be particularly considered for this device are the temperature environment and the atmospheric pressure fluctuation. In such a case, for example, as shown in FIG. 26, when the number of chambers is two, that is, when three waterproof membranes (functional porous membranes) having penetrating fine pores through which moisture can pass are used. , The waterproof membrane and the conductive porous body are fixed by the frame 13 so that the waterproof membrane or the conductive porous body a2 is not tensioned or loosened, and the frame is fixed. In principle, the membranes are guided in parallel by the elastic chamber inner wall 11 so that the membranes move in parallel to each other in the chamber space, and the outside air side and the container side of the inner wall 11 do not lose the airtightness of each chamber. At the end of the moving space such as the frame, the chamber outer wall 12
Only the second membrane and the conductive porous body a2 or the second membrane B fixed airtightly to the second membrane or only the conductive porous body attached to the second membrane or the convection control fin attached to the second membrane is provided, and only the fin is provided. , The volume of the convection volume of the chamber on the container side or the chamber of the outside air or the volume required for stirring caused by the convection necessary for radiative cooling, or the convection control set in the passing air velocity, the conductive porous body, or inside the chamber. In consideration of the influence of fins, etc., as a general rule, the respective membranes or the conductive porous bodies are moved in parallel with respect to the outside air side or the container side, so that the position of the second membrane B or the conductive porous body is Alternatively, the convection control fins or the like move to the container side or the outside air side according to the external temperature. FIG. 27 is a schematic diagram when the temperature of the container or the outside air is raised or the outside air is depressurized. FIG. 28 is a schematic diagram when the temperature of the container or the outside air is lowered or the outside air is pressurized.
FIG. 29 shows a schematic view of an arrangement state when a shape memory alloy is used as the moving means. 30 and 31 are schematic diagrams of the moving method of the movable frame in the case of the atmospheric pressure variation-oriented design. Then, these movements are performed without power by the movement means by the temperature fluctuation of the outer wall 2 or the heat conduction from the container side mounting portion. Examples of the moving means include shape memory alloys and balloons.

Here, based on the results obtained from the test results in this embodiment, the effects of the conductive porous body inside and outside the small chambers or in combination with the moisture permeable waterproof membrane will be summarized.

Characteristics of metal grounding mesh 1. Easier to dry than an equivalent mesh (conductive porous body) that is not grounded. 2. By selecting a material with a high specific heat as the constituent material of the mesh (conductive porous body), a temperature environment lower than the surrounding environment can be generated locally or in the vicinity where the mesh (conductive porous body) is set. it can. At this time, since the volume of the mesh (conductive porous body) decreases as the mesh (conductive porous body) made of the constituent material having the same specific heat becomes thinner, this effect (in the mesh (conductive porous body) or The temperature drop in the vicinity) is reduced. In addition, the higher the area density of the pores, the lower the air permeability, but the more the mesh (conductive porous body) flux obstruction structure, the lower the air permeability. The flux obstruction structure described here is a component that can impede the progress of the flux in the flow passage direction of the stitches, for example, which cannot pass without detouring as the flux progresses. Refers to a sterically hindered structure (eg, zigzag structure of the net). 3. It is electrically neutral. Because it is grounded. Electrical neutralization of the passing gas can also occur. On the other hand, it can also be used as an ion wind electrode. 4. If the constituent material is made of metal, for example, if copper fiber is used, then oligodynamic (OLIGODYNAMIC ACTI
ON) is expected, and it is possible to prevent the growth of mold such as Trichophyton, which is often present in the natural environment, on the same mesh (conductive porous body). Further, also in other parts, an antifungal agent or a material containing an antifungal agent may be appropriately used in consideration of the charging property. 5. Even if a mesh that can be positively charged with an insulating property such as nylon is used as a support mesh on both sides in close proximity to the grounding mesh, it does not impede the dehumidifying effect of this dehumidifier, and the moisture permeability is reduced. It is possible to prevent dust from adhering to the waterproof membrane. Because, Experiment G that I used for a year and a half
The larger dust than the microscopic observation result of the three kinds of films of 2-1 did not adhere at all. 6. The dust removal effect can be promoted without requiring a power source. 7. In the setting in the direction of shutting off the flux in the gas passage direction, in the setting in the entire surface, in the setting in the part that acts like a valve (for example, in the entire horizontal cross-section circle), in the setting in the portion where the flux is stabilized, for example, in the outer circumference of the horizontal cross-section circle. When the mesh (conductive porous body) is set in a ring-shaped concentric circle inside, the temperature tends to be on the exhaust side (the temperature of the outer cylinder becomes low, and the constituent material of the cone cylinder has a temperature higher than that of the ambient air even when resin or metal is used. The flux is stabilized such that the inner concentric circle tends to be on the intake side in the concentric circle on the center side. The selection of a material having a high thermal conductivity depending on the physical properties of the mesh makes it easier to unify the temperature distribution of the film by setting the mesh close to or near the mesh in a single film. It is expected that this effect will increase in proportion to the thickness of the mesh or the number of overlapping meshes, but if it is too thick, the effect will diminish. This is because, for example, when the meshes are overlapped, a temperature distribution (non-uniformity) occurs in the overlapped meshes. There is a strong tendency for the temperature of the passing flux to fluctuate with the temperature of the mesh itself, ignoring the temperature of the passing air in proportion to the increase in the mesh thickness or the number of overlapping. At this time, the shape of the ventilation block structure of the mesh is greatly affected. 8. For the purpose of stabilizing the local temperature gradient, the mesh (conductive porous body) is set before and after or near the moisture-proof waterproof membrane, and at the same time, the flux near the same mesh (conductive porous body) in the dehumidifier is set. It causes a local increase in water vapor density before and after or near the same mesh (conductive porous body) when the velocity is weak. 9. Although it is presumed that the effect is extremely weak, the effect on the generation of ionic wind, though weak, depends on the selection of the moisture-permeable waterproof membrane, and due to the characteristics of its surface potential, ionic wind is generated in some cases. Wind stabilization, or
When using this dehumidifier (vertical type or horizontal type) in an environment where electrostatic charge on the container side or external air side is expected, electrostatic discharge that is inherently possessed by the moisture permeable waterproof membrane due to the generation of ionic wind There is a static elimination effect of the charged gas as a factor that may hinder the physical properties.

# 41 × 80 mesh φ86 mm, # 34
For a total of 4 types with and without grounding in a × 32 mesh φ86 mm, the ultrasonic sprayer sprayed and recorded the temperature fluctuations at the same time with a thermal image, and then changed the condition until drying. Then, the temperature fluctuation was observed in the thermal image. In FIGS. 19, 21 and 22, four kinds of meshes a, b, c and d are arranged clockwise from the upper left, and a is # 41.
× 80 mesh φ86 mm was grounded. b is # 34
× 32 mesh φ86 mm was grounded. c is # 41
× 80 mesh φ86mm without ground,
d shows the one in which # 34 × 32 mesh φ86 mm is not grounded. Each of the meshes of a, b, c, and d is fixed to an acrylic plate having a thickness of about 1 mm on the back surface with an 18 mm acrylic square bar. FIG. 19 is a thermal image analysis diagram showing thermal images of four types of meshes in a state where irradiation and re-water are not sprayed, and infrared irradiation from a heat source is not performed. There is no significant difference between the four meshes.
FIG. 20 shows a thermal image of the humidified state taken from the lower side of the test dehumidifier equipped with the membrane according to the arrangement of Experiment G2-1. The unevenness of the film temperature and the surface temperature is observed. The hammer-shaped image located at i in the figure shows the sensor. FIG. 21 shows a thermal image in a state in which rainwater is sprayed and spraying is stopped after 5 minutes. The support which supports four kinds of meshes and the same mesh are cooled by the spray of rain water, and the temperature state of each blackened mesh is shown. The spray position is at the center of a, b, c, d in the same figure, and the belt-shaped image sandwiched between b, d and having a slightly higher temperature in the vertical direction is the nozzle of the spray device. FIG. 22 is a thermal image immediately after irradiation of infrared rays from a heat source for about 5 seconds after stopping spraying and immediately after stopping the irradiation. It is presumed that the whiter the item, the drier it is. FIG. 23 is a thermal image immediately after the irradiation was stopped by irradiating infrared rays from the heat source for about 5 seconds after the spraying was stopped for 3 minutes. It is presumed that the whiter the item, the drier it is.

Conclusion 1. The # 41 × 80 mesh φ86 mm seems to dry faster, and the # 34 × 32 mesh φ860 seems to dry more slowly. 2. Both # 41 × 80 mesh φ86 mm and # 34 × 32 mesh φ86 mm dry faster when grounded. 3. The order of early drying is as follows: a>b>d> c 940905 17:25:02 015 record after spraying stopped (Fig. 22) (The heat source afterimage was taken with a thermal image after irradiation with the heat source for about 5 seconds) 4 ． It is clear that the specific heat of the mesh (conductive porous body) is higher than that of the membrane (moisture permeable waterproof membrane), using the data obtained by trying to compare the drying rates of four kinds of mesh (conductive porous body) arranged. , If the mesh (conductive porous body) and the waterproof membrane are placed close to each other, the characteristics of the substance with high specific heat will be generated at or near that site. Therefore, a local increase in water vapor density occurs before or after or near the vicinity.

Measurement Results FIG. 24 is a front and back surface potential measurement diagram of each waterproof film immediately after the start of Experiment G2-1, and FIG. 25 shows the measurement results at the end of the same experiment. Both figures are measurement diagrams in which the surface potential of each membrane was measured on the front and back sides of each membrane. The first channel is the outside air side of the third membrane, the second channel is the outer chamber side of the third membrane, and the third channel is FIG. 5 is a surface potential measurement diagram from the outer chamber side of the second membrane, the fourth channel from the inner chamber side of the second membrane, the fifth channel from the inner chamber side of the first membrane, and the sixth channel from the container side of the first membrane. . The measured values are represented in rows of date and time, and in the horizontal direction of the graph, the center indicates OV, the left end indicates -1KV, and the right end indicates + 1KV. According to the results obtained from FIGS. 24 and 25, it is presumed that the membranes as boundaries forming each chamber are probably the result of an increase in the amount of moisture absorption due to the adsorption of water vapor, but in the process where the dehumidifying function acts, The result is that the potential gradually becomes equal and approaches the surface potential 0. Further, comparing the contents of the two measurement results of FIG. 24 and FIG. 25 with the case where the amount of moisture absorption in the same document is not very large, the moisture absorption state of the membrane is The water vapor is saturated and therefore
It is estimated that the surface potential on the surface of the membrane was close to zero. From this, in the dehumidifier of this system, it is advantageous to make the film thickness as thin as possible in order to efficiently improve the water vapor transfer in the chamber bounded by each film. The thickness of the moisture-permeable waterproof membrane (the thickness of the breathable pores may be adjusted to facilitate the adjustment of breathability so that a concentration gradient is generated in each chamber). In addition, it is advantageous to select one with high insulation and low moisture absorption or low water absorption. On the other hand, on the contrary, the water vapor is saturated in many breathable holes in the waterproof membrane, and
It is also deduced that the moisture permeability can be adjusted by changing the thickness of the surface potential on the membrane surface with the passage of time and with dehumidification. In the water vapor permeable waterproof membrane, the saturation phenomenon of water vapor is probably caused by dielectric polarization between water vapor molecules due to electrostatic force, and then after static pressure, that is, when the amount of gas transfer between chambers is extremely small. It is considered that the water vapor molecules present in many pores in the film stay while receiving the dielectric relaxation phenomenon from the film. In this case, a conductive element such as platinum, gold, or the like on the inner side of the pores on the conductive porous body side of the pores or on one side of the membrane as the boundary of the chamber.
Elements such as silver and copper may be arranged by means such as vapor deposition.
Then, a potential gradient may be generated inside the hole. Therefore, the water vapor molecules present in many pores in the membrane adjacent to the grounded conductive porous body tend to be more neutralized, and in the membrane that opens on the opposite chamber side. It is conceivable that the water vapor molecules existing in the same pore, which are present in large numbers in Fig. 1, tend to approach a state depending on the electrostatic properties (charge series and charge amount) of the film itself. Therefore, the arrangement of the conductive porous body is
As described above, the dehumidifying effect is considered to be promoted because it exhibits the effect of relaxing the dielectric polarization of water vapor inside the large number of pores present in the film itself. Further, when considering only the surface of the membrane, if the water-permeable waterproof membrane and the conductive porous body come into contact with each other to some extent, the leakage of the water-soluble metal element from the conductive porous body occurs. , It also impairs the electrical insulation characteristics and electrostatic characteristics of the moisture-permeable waterproof membrane itself. Therefore, in the structure of this dehumidifier, the contact between the conductive porous body and the moisture-permeable waterproof membrane is prevented. No placement is required. This is because, depending on the weather environment, it is sufficiently predicted that dew condensation will occur on the conductive porous body. As this means, there are means for arranging the conductive porous body in tension, and in advance or as a countermeasure against thermal expansion or contraction, gas convection in a position where the dielectric relaxation effect is taken into consideration and inside the chamber, the conductive porous body. A three-dimensional wavefront three-dimensional shape in the direction of the membrane of
Even in the same moisture-permeable waterproof membrane, such a
As a measure against thermal deformation, the thickness of the film is varied so that, for example, when the dehumidifying device is set in a sliced shape, the connecting part between the dehumidifying device and the film is thick and the central part is gradually thinned. Is effective, and in this case, in addition to the purpose of making the deformation of the pore shape of the membrane small, a large number of convections in each chamber space or a large number of moisture permeable waterproof membranes are provided. Taking into account the dielectric relaxation phenomenon of water vapor molecules existing inside the existing pores, the thickness of the moisture-permeable waterproof membrane according to the regional characteristic specifications is appropriately changed to take measures to prevent deformation of the pore morphology. There must be.

Regarding the changes in the amount of moisture absorption and the electrical conductivity of the polymer film, [Electrostatic Handbook 1990 (1989), 11th edition, reprint edition, 11th edition, editor: The Society of Polymer Science and Technology, Jijijinkan Co., Ltd. ISBN4 −
4852-0017-0 C3042 P.I. 40 1.
From 15 or less P. 41] shows the change in conduction current along the film direction due to moisture absorption in the case of a general polymer film. Further, in this, there are described a case where the moisture absorption amount is large and a case where the moisture absorption amount is small, but the moisture permeable waterproof membrane used in the present application mainly exhibits physical properties such as a small moisture absorption amount or a small water absorption. It is assumed that a waterproof membrane will be used. As a supplementary measure, even if the temperature of the breathed air is extremely high, especially if it is likely to be in a high temperature environment, or if the temperature rise on the container side is significant, even in the cooling space. In each chamber as a convection space, or in the exhaust port or intake port of this dehumidifier, a material with high heat dissipation that has the necessary volume for cooling the passing air and with high thermal conductivity, such as aluminum cooling The fins are set in the chamber etc. (also in the exhaust port or the intake port), and the nuclear membrane is set in a position that also takes into consideration the heat radiation characteristics of the conductive porous body, and the volume required for the chamber is set. Alternatively, the size of the device can be reduced.

On the other hand, the following characteristics can be obtained by setting the carbon fiber mesh (weakly conductive porous body). Here, the weakly conductive porous body refers to a so-called resistor, and includes, for example, a metal oxide.

Summary of the effect of setting the weak conductor porous near the membrane For example, the effect of setting a synthetic resin mesh such as a carbon fiber mesh

(1) The stabilization of the local temperature gradient before and after or near the moisture-proof waterproof membrane is inferior to that in the case of the metal mesh (conductive porous body). In the setting in the direction of shutting off the flux in the gas passage direction, in the setting in the whole surface, in the setting in the part that acts like a valve (for example, the entire horizontal cross section circle), in the setting in the portion where the flux is stabilized, for example, in the horizontal cross section circle, When the mesh (electroconductive porous body) is set with a ring-shaped concentric circle on the inside of the outer circumference, it tends to be on the exhaust side (the temperature of the outer cylinder becomes low, and the constituent material of the cone cylinder is lower than that of the ambient air even when resin or metal is used). The temperature is often low.) Also, the flux is stabilized such that the inner concentric circle tends to be on the intake side in the central concentric circle.

In the case of a metal mesh (conductive porous body), a temperature drop of the flux is expected when the flux passes, whereas in the non-conductive porous body, resin fibers such as nylon are used. In that case, since the specific heat is smaller than that of metal, the cooling capacity is inferior, and when resin fibers having a lower thermal conductivity than metal are used, the thermal conductivity is lower than that of metal. In the horizontal type, the effect of unifying these with respect to the temperature gradients at the inner circumference and center of the cylinder is naturally lower than that of the metallic mesh (conductive porous body). As a material having a lower thermal conductivity is selected depending on the physical properties of the mesh, it becomes more difficult to unify the temperature distribution of the film by setting the mesh close to or near the mesh in a single film. It is also assumed that this effect becomes more difficult in proportion to the thickness of the mesh or the number of overlapping meshes, but if it is too thick, conversely,
The local non-uniform temperature becomes large, and the heat retention effect is enhanced, and the moisturization effect is enhanced. This is because, for example, when meshes are overlapped, temperature distribution (non-uniformity) occurs in the overlapped meshes,
The cause is that the specific heat is low and the thermal conductivity is low, and the amount of fluctuation of the electrostatic capacity is larger than that of the film part, causing stagnation. There is a strong tendency for the temperature of the passing flux to fluctuate with the temperature of the mesh itself, ignoring the temperature of the passing air in proportion to the increase in the mesh thickness or the number of overlapping. At this time, the shape of the ventilation block structure of the mesh is greatly affected. This is the same as when it is made of metal. 2 Setting before or after or near the moisture-proof waterproof membrane of non-conductive porous material for the purpose of stabilizing the local temperature gradient is
At the same time, when the flux velocity near the non-conductive porous body in the dehumidifier is weak, it is possible to cause a local decrease in the water vapor density before and after or near the non-conductive porous body by the metallic property. Lower than when using mesh (conductive porous material). In other words, in a non-conductive porous body, for example, when a resin fiber such as nylon is used, the specific heat is smaller than that of metal, so that the cooling capacity is poor and the resin fiber having a lower thermal conductivity than metal is used. When used with, the thermal conductivity is lower than that of metal, so it is inferior when a temperature gradient occurs in that mesh. However, when considering the temperature fluctuations before and after passing through the mesh of the flux, if a material with low specific heat and low thermal conductivity is used as the mesh and the velocity of the flux is sufficiently low, the metal mesh (
In contrast to the case of (conductive porous body), the heat retention effect is more
Become stronger. 3 The static elimination effect before and after a moisture permeable waterproof membrane (moisture permeable membrane) for the purpose of stabilizing the electrostatic capacity gradient in the chamber depends on its conductivity. 4 Such a phenomenon can be executed even if a plurality of concentric rings are used. 5 It is estimated that the effect is extremely weak. However, depending on the selection of the moisture-permeable waterproof membrane, the effect on the generation of ionic wind, although it is weak, is that when ionic wind is generated due to the characteristics of its surface potential. Stabilization of ionic wind (depending on the selection of the material properties of the mesh, and taking into account its electrostatic properties, if a material with a low water absorption rate is selected, it is easy to maintain a dry state forever and the potential is Therefore, it is easy to maintain the high state, and conversely, it is easy to be positively charged with a material having a low water absorption rate and a material having low conductivity (for example, a substance such as thin asbestos, thin glass fiber, etc.) When a mesh made of a material with high conductivity and low conductivity is used, the potential quickly approaches 0, and if the water absorption is low and the conductivity is low, it may become negatively charged (for example, a foam styrofoam). ), And depending on the selection of the physical properties used for such a mesh, a potential gradient is generated between the membrane and a waterproof membrane (moisture permeable membrane) that allows moisture to pass, and ionic wind is generated even though it is extremely weak. In addition, when using this dehumidifier (vertical type, horizontal type) in an environment where charging on the outside air side is expected, due to the generation of ionic wind, or due to the electrostatic properties originally possessed by the moisture-permeable waterproof membrane, Use of a substance having a high electrical resistance, which inhibits the decrease in chargeability due to a charged gas as a factor that may interfere, and which depends on the electrical conductivity or electrical resistance of the constituent material of the waterproof membrane. The more it does, the lower the static elimination effect.

The specific constitution of the present invention is not limited to the above-mentioned embodiments, and the present invention is included in the present invention even if there are design changes and the like within the scope not departing from the gist of the invention. For example, a connection of an electrically grounded conductive porous body in a ventilation path used in the dehumidifier is connected and grounded by a conduction path provided in a through cylinder, and the ventilation is performed by mounting a container in the dehumidifier mounting part. The ground path of the tract may be connectable to ground on the container side.

In the dehumidifier, at least a conductive porous body electrically connected to the ground is attached to a tubular body that is attached to the wall of the container and forms a ventilation path that communicates the inside and the outside of the container. A conductive porous body which is set close to one side of a moisture permeable waterproof membrane and which is connected to an electric resistance body with respect to an insulating or ground wire on the other side; and the waterproof membrane and the conductive porous body. And at least three pairs of air passages are provided inside the tubular body at intervals with the ventilation passages configured as one set, and the ventilation body that shields the hollow space inside the tubular body into at least two chambers is provided. You can also

A conductive porous body which is set at least close to one side of the waterproof membrane and is connected to an electric resistor with respect to an insulating or ground line on the other side, and the waterproof membrane. And a conductive porous body as one set, and at least double bottomed cylindrical ventilation body forming a part of the cylindrical wall. By disposing the ventilation passage inside the tubular body, the ventilation passage may be shielded in a plurality of stages from the inside to the outside of the container. Further, an awning may be provided outside the tubular body.

In the grounding circuit of the conductive porous body, in addition to the fixed resistance, temperature sensors such as thermistors set on the chambers, containers, and the outside air side are used as variable resistances. ) According to the air passage in each chamber, the inside and outside of the conductive porous body, the sunshade section set outside the dehumidifier, the solar cell section, the outer wall section,
By selecting separate thermistors (NTC, PTC, CTR, etc.) with appropriate characteristics for the ventilation passage and the mounting part on the container side, the ground circuit resistance of each conductive porous body or The impedance may be adjusted according to the fluctuation of the external environment or the temperature fluctuation of the container side. In addition, a temperature switch (such as a temperature-sensitive reed switch) may reversibly disconnect or connect the ground circuit at a specific temperature of each part.

As the power source of the embodiment of claim 10,
A solar cell attached to a shade or a side wall of the container may be used as a power source. Since the amount of current generated at this time varies depending on the light receiving state, the driving of the cooling / heating element may be adjusted using this time.

Further, a ventilation body which generates heat by absorbing moisture may be set in the ventilation passage, or a moisture-permeable waterproof film having a property of generating heat by absorbing moisture may be set in the ventilation passage. However, in these cases as well, in consideration of the temperature gradient or the water vapor concentration gradient, the moving direction of the water vapor is actively controlled to promote the discharge. Further, it may be applied to suppress the backflow by forming a reverse gradient.

In order to prevent disturbance, the tubular body may have a double-walled structure, and the chamber space may be kept warm so as not to adversely affect the generation of the temperature gradient in each chamber. The most ideal method for attaching the dehumidifier is to contact the inner wall of a container having a heat retaining layer, for example, a container having a metal laminate structure filled with urethane, with the container-side wall of the device. In addition, by contacting the outside air-side wall of the device with the outside of the container, the dehumidification effect is promoted, and in addition, the inflow of outside-air-side water vapor into the container is suppressed, and it can withstand significant fluctuations in the outside air. Easy to obtain the effect. This is because the electric equipment to be housed often generates heat, and the outer wall of the container often shows remarkable temperature fluctuations, which is often long during the total dehumidification time (in Japan).

In addition, mounting to a container having no heat insulating layer is
The container side of the present device may be brought into contact with the same theory in a state of protruding to the outer wall of the container.

Further, the heat insulating side of the waterproof membrane is a container so that the conductive porous body and the waterproof membrane (functional porous membrane) do not hinder the electrostatic characteristics of the same membrane, that is, the chargeability, that is, the electrical insulation strength. When the heat-insulating side (nonwoven fabric side) is arranged on the container side by arranging in the same way as the arrangement of Experiment G2-1 in the state facing the side, a structure or conductivity having conductivity on the surface of the non-woven fabric It is also possible to have a structure in which the fibers having the above or the vapor deposition layer of the conductive material is integrated with the above film.

In addition, the insect-proof net or dust-proof net may have a shape with a hanging central part so that it is difficult to hold water drops, or the insect-proof net or dust-proof net may have a shape that is easy to dry (especially top and bottom) to prevent windstorms. You may provide the fin of a shape with few recesses).

In each chamber, which is a passage space for the air that is breathed between the container and the outside air, an accumulator that opens to the outside air side is set, and when the temperature or pressure changes rapidly in the external environment in which the container is placed, When abrupt decrease of the external temperature or abrupt increase of the external atmospheric pressure is occurring, between the chambers, the accumulator of the accumulator is used for the purpose of preventing the inflow of the air containing the water vapor particles from the outside air into the container side. In the event of an enormous amount of air, the chamber may be brought into close contact with the side wall of the chamber, or in order to limit the inflow velocity, the cross-sectional area of the air passing through the accumulator during the enormous amount of the accumulator may be limited or blocked. Good. Also, of course, the accumulator may be set in plural or in single.

Alternatively, it is possible to prevent clogging of a dustproof net or the like.

The volume fluctuation of the chamber space or the movement of the conductive porous body or the convection control fin may be manually performed from the outside. The frame 13 may be moved electrically to the outside air side or the container side by screwing the outer wall (cylinder) 12, for example.

Further, in the dehumidifying device of claim 10,
In particular, the temperature inside the container, each chamber, the outside air temperature, etc. may be detected by a temperature sensor, and the respective positions may be changed in accordance with the microcomputer control.

Regarding the moving means of the frame, in addition to the parallel movement, the airtightness between the container side and each chamber space or the outside air side of one small chamber, etc. is ensured, and the convection phenomenon of the ventilation path is not hindered. As the means, the moving means such as the moving frame may be a spiral movement.

In addition to the shape memory alloy used for moving the moving frame or the like, the inner wall 1 may be made of a flexible elastic body that contracts. Further, the inner wall 1 may be formed of a moisture-permeable waterproof film, and at this time, since the property of the hole changes at the bent portion, the film may be set at a position avoiding this portion. Further, the material of the bent portion expands and contracts due to a change in hygroscopicity. For example, the movement of the frame may be adjusted by using natural fibers such as cotton and silk as the non-woven fabric.

When a remarkable temperature change occurs and the outside air temperature easily rises to a high temperature, as shown in FIG. 30, the inner wall 14a is set to a chamber on the container side, and a flexible elastic body that shrinks is set. And an inner wall 14a positioned outside the inner wall 14a forming a space 14c closed by the inner wall 14a as the temperature of the outer wall 15 rises or the temperature of the container side (the inner wall of the container or the outer wall) rises. To form a portion 14b continuous with. The inner space 14c has a temperature rise,
The air or gas contained therein expands to reduce the cross-sectional area of the gas passing through the chamber on the container side, and at the same time,
The membrane B is moved to the outside air side. At this time, since the inner walls 14a and 14b have a donut-shaped balloon body as a form, even if the temperature of the outer wall 15 of the container or the present apparatus rises unevenly, the second film B may be changed to the first film A or the third film C. Can move parallel to. When the temperature drops, the inner space 14c shrinks, the cross-sectional area of the air passage is enlarged, and the second film b is brought closer to the first film A side.

The inner wall 14a or 14b may be thinned at the maximum bulge so as to promote the above movement. Further, the inner wall 11 of FIG. 26 may be present at a position other than the balloon portion (accumulator portion) of the inner wall 14a or 14b of FIG.

4 is set to the outside air chamber, is composed of a flexible elastic body that contracts, and a traffic path 1 that communicates with the outside world through a waterproof film 19 having through-holes with high permeability and moisture permeability in the outer wall portion.
8 may be provided at the bottom of the elastic content. In this case, as the outside air is decompressed, the elastic body contracts so as to come into close contact with the outer wall 15, and at the same time, the chamber on the outside air side shrinks, and conversely, the elastic body expands as the outside air increases in pressure, and the second body expands. The membrane B is made to approach the first membrane A side, that is, the container side in parallel, and the volume relationship between the chambers that suppresses the movement of the water vapor contained in the outside air toward the container side is maintained, and the relative inside of the container due to the temperature rise of the outside air. Backflow phenomenon due to the temperature decrease phenomenon,
It is possible to suppress the backflow phenomenon due to the back pressure that is generated due to the difference in the ventilation amount of the waterproof membrane having the penetrating fine holes through which moisture can pass.

Further, the sliding form of the moving portion on the outer wall 15 may be provided with a groove serving as a guide for limiting the moving state such as the parallel movement or the spiral movement.

The conductive porous body is set close to at least one side of the waterproof membrane, and the ventilation membrane constituted by the waterproof membrane and the conductive porous body as a set allows the conductive porous body to be in the air or the surrounding environment, or on the container side. The dehumidifying effect is not obtained by the conventional dehumidifying device, that is, the dehumidifying device only divided into the small chambers that are shielded in multiple stages by the moisture-permeable waterproof film because the chargeability of the gas is removed.

Utilized humidity gradient between each small room By appropriately selected depending on the environment, there is an advantage that it is possible to promote the dehumidifying effect.

According to the dehumidifying device of claim 7,
An electrically grounded conductive porous body in a ventilation path used in the dehumidifying device according to 2, 3, 4, 5 or 6,
By having a wave-shaped or concentric shape set at a position that takes into consideration the convection phenomenon of each chamber, the dehumidified side is adjusted according to the vibration of the flux due to the concentration of convection gas due to the convection phenomenon inside each small chamber. Due to the shape arrangement at the position considering the temperature difference between the temperature and the outside air temperature, even in the same conductive porous body, the part where the flux is large and the part where the flux is small are the flow velocity, that is, the flow velocity and the flux Since it varies depending on the flux and the gas density of the outside air, it is not possible to design a simple concentric circle as an unstable structure in order to design the conductive porous body in the most appropriate exhaust side passage due to this variation. Since elements may occur, the dehumidifying effect is improved and the absorption is improved by selecting the shape that maximizes the effect of the conductive porous body by combining these or by combining them alone. There is an advantage that it is possible to suppress the intake rate of the outside air side of the gas at the same time during.

In the dehumidifying apparatus according to the eighth aspect, the moisture can be used as the boundary of each chamber by utilizing the potential gradient of the electric resistor or without separately connecting the electric resistance to the conductive porous body. The effect that the constant drying speed can be adjusted by adjusting the electrostatic potential gradient in the vicinity of the waterproof film or adjusting the water vapor concentration can be obtained.

In the dehumidifying apparatus according to the ninth aspect, there is an effect that the drying speed can be adjusted without separately providing the electric resistance element to the ground circuit.

In the dehumidifying device of the tenth aspect, a temperature gradient is artificially generated in the set region of the conductive porous body and the moisture permeable waterproof film, and as a result, the charging phenomenon is highly insulating. , An electrostatic gradient is generated on the surface of the porous sheet made of, for example, tetrafluoroethylene or polyethylene, and the potential gradient that promotes the dehumidifying effect between the chambers or in the vicinity of the same membrane and the conductive porous body is weak. However, it has the effect of continuously operating and promoting the dehumidifying effect together with the generation of the temperature gradient between the chambers by utilizing the fluctuation of the power generation amount due to the fluctuation of the ambient sunlight irradiation amount.

In the dehumidifier according to claim 11, a temperature gradient is artificially generated in the set region of the conductive porous body and the moisture permeable waterproof film, and as a result, the charging phenomenon is highly insulating. , An electrostatic gradient is generated on the surface of the porous sheet made of, for example, ethylene tetrafluoride or polyethylene, and the potential gradient that promotes the dehumidification effect between the chambers or in the vicinity of the same membrane and the conductive porous body is weak. However, the effect of continuously acting and the effect of accelerating the dehumidifying effect together with the generation of the temperature gradient between the chambers by utilizing the fluctuation of the power generation amount accompanying the fluctuation of the ambient sunlight irradiation amount can be obtained.

In the dehumidifying apparatus according to the twelfth aspect, due to the movement of the film, the dehumidification occurs due to the distance relationship between the chamber on the container side and the chamber on the outside air side, the volume relationship, the outside air temperature, and the abrupt pressure change of the outside air. The dehumidifier is inconsistent with conditions such as the temperature gradient between chambers and the electrostatic capacitance gradient that accompanies the concentration gradient of water vapor between chambers, such as backflow phenomenon and reverse temperature gradient. Can be buffered and the dehumidification on the container side can be maintained in a more stable state. As a general rule, it is possible to change the dehumidification of the interior space of the container, which is the dehumidification target space, in response to a significant change in the external environment with no power supply and no power supply. It is also possible to prevent the adiabatic cooling of the fins or the side wall of the chamber and also to prevent dew condensation inside each chamber space more safely.

When a shape memory alloy is used as the moving means, parallel movement can be performed depending on the temperature variation of the outer wall, but in this case, frictional resistance occurs when the moving portion moves. .

When the membrane is composed of the membranes 3, the second membrane is moved to the outside air side, that is, by making the volume of the container side chamber larger than the volume of the outside air side chamber, the conductive porous body or In a state where the diffusion energy of the water vapor inside the container that has passed through the first membrane is sufficiently preserved, the water vapor is moved to the outside air side by passing through the conductive porous body and the membrane of the second membrane portion. In addition to accelerating, by reducing the volume of the chamber on the outside air side, the total amount of total movement due to convection of air in the outside air chamber is reduced, and the relative decrease in temperature inside the container due to the rise in temperature of outside air is reduced. The backflow phenomenon due to back pressure caused by the backflow phenomenon caused by the difference in the ventilation amount of each waterproof membrane having through micropores through which moisture can pass is suppressed, and the backflow phenomenon from the chamber on the container side to the outside air side is suppressed. Promoting the diffusion of water vapor into over, as a result, it is possible to promote the diffusion of water vapor from the container side chamber to the outside air, to promote dehumidifying effect.

On the other hand, when the temperature of the outer wall decreases due to the temperature decrease of the outside air or the like, or the temperature decrease of the container side, the moving part approaches the container side, and is caused by the convection of the air in the chamber on the outside air side. By increasing the total moving amount and slowing the moving speed of water vapor on the outside air side to the container side, and when viewed from the container side, the volume of the container side chamber decreases compared to the volume of the outside air side chamber. As a result, the transfer rate of water vapor from the container to the outside air is promoted, and
There is also an effect of suppressing a backflow phenomenon due to a decrease in temperature drop and a backflow phenomenon due to a back pressure that occurs due to a difference in the ventilation amount of each waterproof membrane having penetrating fine holes through which moisture can pass.

The balloon also has a heat retaining effect,
It also has the dual effect of promoting the dehumidifying effect while buffering the rapid heat conduction from the container side.
