Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a dehumidifier for dehumidifying using a deliquescent hygroscopic agent.

[0002]

2. Description of the Related Art Conventionally, a dehumidifier using a deliquescent hygroscopic agent has been widely used for the purpose of dehumidifying the inside of a closet or a closet. As such a dehumidifier, for example, the container body is divided into two space parts, an upper space part and a lower space part, by a saucer having a plurality of deliquescent solution dropping holes, and the upper space part is powdery or granular. There is a structure in which a deliquescent hygroscopic agent such as calcium chloride or magnesium chloride in the form of particles or granules is packed, and the deliquescent deliquescent liquid is stored by absorbing moisture by contacting moisture in the outside air in the lower space, While covering the opening of the main body with a film-like moisture-permeable and water-impermeable non-permeable moisture-permeable / water-permeable film, the film-like moisture-permeable / water-impermeable film is covered with a lid to protect it. The lid is provided with a ventilation part so that the outside air containing moisture is guided to the deliquescent hygroscopic agent.

In this dehumidifier, moisture in the outside air passes through a ventilation part provided in the lid and then permeates a moisture-permeable / water-impermeable film,
It contacts the deliquescent hygroscopic agent packed in the upper space of the container body. Then, when the moisture in the outside air comes into contact with the deliquescent hygroscopic agent, deliquescent liquid is eventually generated, and the deliquescent liquid is dripped into the lower space portion of the container body through the drip holes formed in the saucer and stored. Will be done. The moisture absorption rate of the deliquescent hygroscopic agent at this time is determined by the proportion of outside air that contacts the deliquescent hygroscopic agent packed in the upper space, so in this dehumidifier, the proportion of outside air taken into the upper space is Depending on the coating area of the opening of the main body, the larger the coating area, the greater the ratio of contact between the outside air and the deliquescent hygroscopic agent and the higher the moisture absorption rate. In the dehumidifier configured as described above, about 25 g of deliquescent liquid was obtained in 4 days, and about 50 g of deliquescent liquid was obtained in 8 days.

However, if the film area of the opening of the container body is increased as described above in order to improve the moisture absorption rate, the container body will have a large bottom area, so this container body is installed. A large space is needed to do this. In addition, since the sheet-shaped moisture-permeable / water-impermeable coating covering the opening of the container body has a thin thickness of several tens of micrometers to several hundreds of micrometers, the dehumidifier is manufactured or handled, or There is a risk of breaking the moisture-permeable / water-impermeable coating during transportation. Should the moisture-permeable / water-impermeable coating that covers the opening breaks, the deliquescent hygroscopic agent packed in the upper space will be removed from the container body. It may be spilled to the outside or the deliquescent liquid stored in the lower space may flow out and contaminate clothing, futon, furniture, etc., so it is difficult to handle and care must be taken. It was

Further, as described above, since the moisture absorption rate depends on the ratio of the outside air contacting the deliquescent hygroscopic agent, a dehumidifier designed to increase the ratio of the outside air leading to the deliquescent hygroscopic agent is disclosed in Japanese Patent Laid-Open No. Sho-61-200. 57-1072 and Japanese Utility Model Publication 4-898.
No. 5 discloses this. According to these dehumidifiers, in order to increase the ratio of contact between the deliquescent hygroscopic agent such as sodium chloride and the outside air, the deliquescent hygroscopic agent is larger than the film area of the opening of the container body provided with a large number of through holes. Are arranged inside a dome-shaped member formed in a substantially hemispherical shape. In this dehumidifier, outside air enters the inside of the dome-shaped member from the ventilation part of the dome-shaped member with a large surface area and contacts the deliquescent hygroscopic agent to generate deliquescent liquid, which is stored in the container body. It is supposed to be done.

Further, in Japanese Utility Model Publication No. 61-10743, a deliquescent hygroscopic agent is covered with a semipermeable membrane having flexibility and having a high followability to form a hemispherical shape, thereby increasing the proportion of contact with the outside air. On the other hand, there is disclosed a dehumidifier that prevents the deliquescent liquid stored in the container from flowing out of the container when the dehumidifier is overturned. In this dehumidifier, outside air containing moisture passes through the semipermeable membrane and comes into contact with the hygroscopic agent to generate deliquescent liquid, and the deliquescent liquid flows down and is stored in the container. At this time, the deliquescent hygroscopic agent contacts the moisture in the outside air and deliquesces, whereby the deliquescent hygroscopic agent decreases and gradually deforms from the hemispherical shape in the initial state.
Since the semipermeable membrane is flexible, the state in which the semipermeable membrane and the hygroscopic agent are in close contact is always maintained, and the moisture absorption efficiency of the deliquescent hygroscopic agent in the semipermeable membrane is maintained.

[0007]

However, in the dehumidifier disclosed in JP-A-57-1072 or JP-B-4-8985, the deliquescent liquid is stored in the container body. If the dehumidifier is tumbled in this state, it was stored from the ventilation part formed in the dome-shaped or hemispherical member that contains the deliquescent hygroscopic agent arranged at the top of the container body. There was a problem that the deliquescent liquid would flow out.

In the dehumidifier disclosed in Japanese Utility Model Publication No. 61-10743, a porous bottom plate having a plurality of through holes is mounted on the flange of a cylindrical container to cover the opening of the container. A hemispherical heap of a hygroscopic agent is formed on the porous bottom plate, and the outer surface of the hygroscopic agent is closely adhered to and covered with the semipermeable membrane, and the periphery of the semipermeable membrane is adhered to the peripheral edge of the porous bottom plate. Since the outer periphery of the semipermeable membrane is covered with a hemispherical mesh lid, and a peripheral edge of the mesh lid is provided with a locking portion that can be detachably attached to the flange of the container by using the periphery of the porous bottom plate as a packing. However, there is a problem that assembly becomes complicated due to the large number of parts.

Further, since the moisture-permeable / water-impermeable film is formed of a semi-permeable film, it may be damaged during assembly.

The present invention has been made in view of the above circumstances, and the contact ratio between the outside air and the deliquescent hygroscopic agent is large,
It is an object of the present invention to provide a dehumidifier having a simple assembly structure in which the deliquescent liquid stored in the container body does not flow out when the dehumidifier falls.

[0011]

The dehumidifier of the present invention comprises a deliquescent hygroscopic agent that absorbs moisture when contacted with the outside air and deliquesces, and a moisture-permeable portion that forms a containing portion for containing this deliquescent hygroscopic agent. And a container body having a reservoir for storing the deliquescent liquid when the deliquescent hygroscopic agent deliquesces, a moisture-permeable portion for accommodating the deliquescent hygroscopic agent, and a moisture permeability for guiding outside air into the accommodating portion. It is formed three-dimensionally by a structural member that has a water-impermeable property that prevents the deliquescent liquid from leaking to the outside and has moldability.

Further, the moisture-permeable portion and the container body are fixed in close contact with each other by a fixing means.

According to this structure, since the moisture permeable portion for accommodating the deliquescent hygroscopic agent is formed three-dimensionally by the structural member having moisture permeability, a large amount of outside air is taken into the moisture permeable portion and deliquescent The rate of contact between the hygroscopic agent and the outside air increases. Further, since the moisture-permeable part is formed of a structural member having moldability,
The handling is easy and the assembly workability is improved. further,
The moisture-permeable portion is formed of a water-impermeable structural member, and the moisture-permeable portion and the container body are closely fixed by the fixing means so that they are integrally fixed. The deliquescent liquid stored inside does not leak outside.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 relate to an embodiment of the present invention, and FIG. 1 is a diagram illustrating a schematic configuration of a dehumidifier, FIG.
[Fig. 3] is an exploded view for explaining the assembly structure of the dehumidifier.

As shown in the figure, the dehumidifier 1 is a substantially hemisphere having a deliquescent hygroscopic agent 2 that absorbs moisture by contacting moisture in the outside air and deliquescing, and a space 3a for accommodating the deliquescent hygroscopic agent 2. The moisture-permeable portion 3 formed of a member having a moisture-permeable and water-impermeable property, which will be described later in a three-dimensional shape, and the deliquescent hygroscopic agent 2 contact the moisture in the outside air and store the deliquescent liquid 8 deliquesed. It is mainly configured by a substantially cylindrical container main body 4 having a storage portion 4a which is a space portion for storing.

The member of the container body 4 is not particularly limited as long as it is a structure which does not allow the deliquescent liquid to leak out, and a circular body opening 4b having a radius r is provided at the upper end of the container body 4.
And an upper end protrusion 4d protruding from the outer peripheral surface of the container body 4 having the male screw 4c formed on the outer peripheral surface.

The moisture permeable portion 3 has, for example, a substantially hemispherical shape, and is substantially hemispherical with respect to the opening area of the moisture permeable portion opening 3b facing the circular main body opening portion 4b having the radius r of the container body 4. The ratio of the outer surface area of the surface is set to 180% or the like to form a three-dimensional convex shape. At this time, the ratio of the outer surface area to the opening area of the moisture permeable portion opening 3b is 200%.
When the moisture permeable portion 3 is formed into a three-dimensional hemispherical shape by setting to, since the shape of the moisture permeable portion opening 3b is a circle,
Since the area of this circle can be represented by πr ² and the surface area of the sphere can be represented by 4πr ² , the outer surface area is 200 mm of the moisture permeable portion opening 3b.
When set to%, the value of the outer surface area becomes 2πr ^2, and this outer surface area corresponds to exactly half the surface area of the sphere, and the shape of the moisture permeable portion 3a becomes a hemispherical dome shape. . In addition, an edge portion 3c formed to have substantially the same diameter as the upper end convex portion 4d of the container body 4 is formed on the outer periphery of the moisture permeable portion opening 3b of the moisture permeable portion 3a.

The deliquescent hygroscopic agent 2 contained in the space 3a of the moisture-permeable part 3 is made of a nonwoven fabric having high air permeability and water permeability so that it can be easily contained in the space 3a. It is accommodated in a bag-shaped package 5. And
In order to securely arrange and store the package 5 containing the deliquescent hygroscopic agent 2 in the space 3a of the moisture permeable portion 3, a circle is formed so as to close the moisture permeable portion opening 3b of the moisture permeable portion 3. A plate-shaped partition member 6 is arranged between the moisture-permeable portion 3 and the container body 4. The partition member 6 has substantially the same diameter as the upper end convex portion 4d of the container body 4, and is provided with a plurality of through holes 6a through which the deliquescent liquid 8 passes.

The moisture-permeable portion 3 for containing the deliquescent hygroscopic agent 2 and the container body 4 for storing the deliquescent liquid 8 are separated by the partition member 6 between the moisture-permeable portion 3 and the container body 4. In this state, the substantially tubular fixing member 7 having the through-hole 7a as the fixing means is integrally and closely fixed. A female screw 7c that meshes with the male screw 4c of the container body 4 is formed on the inner peripheral surface of the fixing member 7. By engaging the female screw 7c with the male screw 4c, the top surface 7b of the fixing member 7 is a partition member. 6, the lower end surface of the edge portion 3c, the upper end surface of the partition member 6, and the lower end surface of the partition member 6 and the upper end surface of the upper end convex portion 4d are integrally and closely fixed to each other to form the dehumidifying container 1. It is supposed to be done.

Here, the moisture permeable portion 3 will be described. The moisture permeable part 3 is provided with sufficient moisture permeability, sufficient water impermeability, and moldability capable of being three-dimensionally formed (hereinafter referred to as moldability), for example, ultrahigh. It is a molded porous structure having a plurality of fine through holes formed of a molecular weight polyethylene material.

Considering the basic performance as sufficient moisture permeability of the dehumidifier 1, the porous structure has a moisture permeability of 1,000 g / m ²
・ It is desired to be more than day. The moisture permeability of this porous structure can be improved by increasing the pore size of the fine pores of the porous structure or by increasing the porosity, but it is not possible to increase the moisture permeability excessively. In this embodiment, the upper limit value of the moisture permeability of the moisture permeable part 3 is set to 6,000 g / m ² · day because it causes a decrease in water impermeable property.

Further, considering the basic performance of the dehumidifier 1 as having sufficient water impermeability, the porous structure has a water pressure resistance of 10 cm or more, although it depends on the shapes of the permeable portion 3 and the dehumidifier 1 as a whole. Is desired. However, when the deliquescent hygroscopic agent 2 is almost eliminated in the dehumidifier 1 in which the moisture permeable portion 3 is arranged above the main body opening 4b of the water impermeable container main body 4,
Several hundred ml of the deliquescent liquid 8 will be stored in the storage section 4a. Therefore, in this state, even if the dehumidifier 1 should fall down, the impermeable liquid 3 of the moisture permeable part 3 should never leak the deliquescent liquid 8 to the outside of the dehumidifier 1. In this embodiment, the water pressure resistance is set to 20 cm or more in order to sufficiently hold the water pressure.

Further, the moldability of the porous structure is not particularly limited as long as it can be formed three-dimensionally, but the thickness dimension of the porous structure forming the moisture permeable part 3 is not limited. With regard to the above, it is desirable to be within the range of 0.5 mm to 6.0 mm, and particularly when the thickness dimension is 0.2 mm or less, it becomes difficult to mold and it is possible to secure the mechanical strength as a structural member. It becomes impossible to set the thickness dimension to 0.
When the thickness is set to 5 mm or more, the mechanical strength is greatly increased, and it is difficult for the mechanical strength to be damaged, so that the handleability is improved. On the other hand, if the thickness dimension is 5.0 mm or more, shaping becomes difficult.

When the porous structure is subjected to a water repellent treatment to improve the water impermeability, it is possible to further increase the moisture permeability, and the water repellent treatment does not affect the product. There is no inconvenience, and it is rather desirable that the porous structure is subjected to water repellent treatment.

The three-dimensional shape of the moisture permeable portion 3 is not particularly limited to the dome shape, but a large amount of the outside air outside the dehumidifier is taken into the inside of the dehumidifier to remove the deliquescent hygroscopic agent 2 and the outside air. In order to increase the contact ratio of the moisture permeable portion 3 with the surface area of the moisture permeable portion 3, the opening area of the body opening portion 4b of the container body 4 is 110% to 2%.
It is preferable to design it so as to be in a range of 50%, and in this embodiment, since the moldability is good, the moisture permeable portion 3 is formed into a dome shape or the like as described above, and the outside air and the deliquescent hygroscopic agent 2 are formed. We are trying to increase the rate of contact with.

Here, an example of a method for producing a porous structure made of the ultra high molecular weight polyethylene material will be described. First, in order to obtain a porous structure, the ultrahigh molecular weight polyethylene powder is filled into a mold, and then the inside of the mold is heated to a temperature equal to or higher than the melting point of the ultrahigh molecular weight polyethylene so that the ultrahigh molecular weight polyethylene in the mold is heated. Is sintered to obtain a block-shaped molded body.

Next, after cooling the die, the block-shaped porous structure is taken out from the die, and the porous structure is cut to a predetermined thickness with a lathe or the like to form a porous structure. Get a disc sheet.

Then, the porous structure disk sheet obtained as described above is subjected to a shaping process to form a dome shape.
At this time, the porous structure disc sheet was heated from 120 ° C to 180 ° C.
After being heated to between 0 ° C and sandwiched in a ring-shaped mold, a convex mold is press-fitted to form a three-dimensional shape. The three-dimensional shape of the moisture permeable portion 3 at this time is a dome shape in which shaping is relatively easy and the outer surface area is large as described above.

When the porous structure is obtained by the above-mentioned manufacturing method, since the ultrahigh molecular weight polyethylene powder filled in the mold is sintered in a heated steam atmosphere, at least heated steam is applied to this mold. An opening for introduction is provided.

Further, during sintering, the ultra high molecular weight polyethylene powder is heated to a temperature above the melting point to be in a molten state, but since the ultra high molecular weight polyethylene has a high melt viscosity, it does not flow and has a shape in a powder state. While maintaining almost all of the above, the contact parts of adjacent powder particles are heat-sealed, while the non-contact parts of the powder particles become micropores of the porous structure, and the block of the porous structure having a plurality of micropores. Is molded. The time required for the sintering at this time varies depending on the filling amount of the ultra high molecular weight polyethylene powder and the temperature of the steam, but it usually takes about 1 to 12 hours.

Furthermore, since the steam is heated to a temperature above the melting point of the ultrahigh molecular weight polyethylene, it is in a pressurized state, so that the water vapor easily penetrates between the ultrahigh molecular weight polyethylene powders filled in the mold. Therefore, the sintering of the ultra-high molecular weight polyethylene powder filled in the mold is performed by a method in which a steam introducing pipe is provided in the pressure resistant container, and an opening / closing valve provided in the steam introducing pipe is opened to introduce heated steam. .

In order to allow heated steam to more easily penetrate between adjacent powders of the ultra-high molecular weight polyethylene powder filled in the mold, the polyethylene powder is charged into the mold and then the mold is opened. It is advisable to place it in a pressure resistant container, depressurize it under a reduced pressure in the range of about 1 mmHg to 100 mmHg, and then sinter in a heated steam atmosphere.

Furthermore, when the block-shaped porous structure after sintering is cooled, rapid cooling is avoided in order to prevent cracks from occurring in the porous structure. Therefore, a cooling method of leaving it at room temperature is adopted. At this time, the block-shaped porous structure may be left in the mold or may be taken out from the mold.

Next, the moisture permeable portion 3 of the dehumidifier 1 of this embodiment.
An example of a specific manufacturing method of will be described. First, in order to form a porous structure for forming the moisture permeable portion 3, the ultrahigh molecular weight polyethylene powder is placed in a mold having a cylindrical space portion whose inner diameter is set to the outer diameter of the container body 4. Fill. Then, this mold is placed in a metal pressure resistant container, the vacuum pump is operated to reduce the atmospheric pressure to 30 mmHg, and the air between the filled powders is degassed. After deaeration, the vacuum pump is stopped and the steam introducing valve is opened to introduce steam of 6 atm at a temperature of 158 ° C. into the mold. In this state, heat for 60 minutes. As a result, the ultrahigh molecular weight polyethylene powder in the mold is sintered into a round rod-shaped porous structure.

Next, the mold on which the round rod-shaped porous structure is formed is left to cool at room temperature of 25 ° C. for 3 hours. From the cooled mold, the diameter of the container body 4
Then, the round bar-shaped porous structure having the outer diameter dimension is taken out.

Next, the porous structure is cut by a lathe to have a thickness of 1 mm, for example, and the diameter is approximately the same as the outer diameter of the container body 4, and the thickness is 1 mm.
Porosity 25%, average pore diameter 30 μm, Gurley value 4 seconds / 1
A 00 mm ² white opaque porous structure disc sheet is obtained.

The ultrahigh molecular weight polyethylene porous structure disk sheet obtained as described above is dipped and impregnated with a fluorine-based water repellent in, for example, a liquid having a solid concentration of 3% at a speed of 1 m / min. Dry at 130 ° C. to solidify and fix. As a result, the water pressure resistance of the porous structure disk sheet was 20 cm, and the water vapor transmission rate was 4000 g / m ² · day.

Then, after cutting this ultra-high molecular weight polyethylene porous structure disk sheet into a predetermined size, this porous structure disk sheet is heated at 140 ° C. for 1 minute to make the diameter size slightly larger than 2r. After being sandwiched by a ring-shaped mold having a set through hole, the convex portion is press-fitted, shaped and cooled to form the moisture-permeable portion 3 having a convex three-dimensional shape.

Here, the operation of the dehumidifier 1 of this embodiment will be described. First, the container body 4, the partition member 6, the moisture permeable portion 3,
A package 5 containing the fixing member 7 and the deliquescent hygroscopic agent 2 is prepared.

Next, the partition member 6 is arranged on the upper end surface of the main body opening 4a of the container main body 4, and the package 5 containing the deliquescent hygroscopic agent 2 is placed on the upper end surface of the partition member 6.

Next, the dome-shaped moisture-permeable part 3 is placed on the upper surface of the partition member 6 on which the package 5 is placed. Then, the through hole 7a of the fixing member 7 is inserted into the convex dome portion, the fixing member 7 is arranged on the upper surface side of the edge portion 3c of the moisture permeable portion 3, and the female screw formed on the fixing member 7 is formed. Part 7
c is screwed onto the male screw portion 4c of the container body 4 to allow the moisture-permeable portion 3
Then, the partition member 6 and the container body 4 are brought into close contact with each other and integrally fixed.

The dehumidifier 1 formed as described above is placed at a desired position such as a clothes dance. After a while, the outside air penetrates into the moisture-permeable portion through a plurality of fine holes provided in the dome-shaped moisture-permeable portion 3. The outside air that has entered the moisture-permeable portion passes through the packaging body 5 and comes into contact with the deliquescent hygroscopic agent 2.

Then, the deliquescent liquid 8 is generated by the contact of the deliquescent hygroscopic agent 2 with the outside air. The deliquescent liquid 8 passes through the through holes 6 a provided in the partition member 6 and the container body 4
Are stored in the storage section 4a. At this time, the moisture-permeable part 3
By forming the dome shape, the amount of outside air that enters the moisture-permeable part increases, so that the ratio of contact between the outside air and the deliquescent hygroscopic agent 2 increases, and the deliquescent of about 70 grams in four days. A liquor is obtained and in about 8 days about 100 grams of deliquescent liquor is obtained.

As described above, the moisture-permeable portion, which is a storage portion for storing the deliquescent hygroscopic agent, is a three-dimensional sheet made of a porous structure having moisture permeability and water impermeability and moldability. By forming the dehumidifier, it is possible to increase the outer surface area of the moisture permeable portion capable of guiding the outside air to the deliquescent hygroscopic agent and prevent the deliquescent liquid from leaking.

Further, since the sheet made of the porous structure forming the moisture permeable portion has a mechanical strength and is set to a thickness having moldability, the productivity is greatly improved and The handling becomes easy, and the production cost and the processing cost can be reduced.

Further, the container body, the partition member, the moisture permeable part,
When assembling the dehumidifier composed of the fixing member and the package containing the deliquescent hygroscopic agent, the moisture-permeable part and the container body are in close contact with each other by the fixing member so that the dehumidifier can be assembled integrally. It is possible to greatly improve and reduce the assembly cost.

The thickness of the porous structure sheet according to the present invention is 0.8 mm to 1 in consideration of moisture permeability, water impermeability, moldability, product stability, productivity and moisture absorption capacity. By setting it in the range of 0.5 mm, the mechanical strength can be greatly increased without impairing the moldability. As a result, the moisture-permeable part can be repeatedly used, the deliquescent hygroscopic agent contained in the moisture-permeable part is lost, and the deliquescent liquid is stored in the storage part. By decomposing the dehumidifier in the reverse order of the procedure and discarding the deliquescent liquid stored in the storage part, replacing it with a package containing a new deliquescent hygroscopic agent and reassembling,
The dehumidifier 1 can be repeatedly used, and the dehumidifier contributing to resource saving is provided.

The container body 4 may be formed of a porous structure in order to increase the ratio of contact between the deliquescent hygroscopic agent 2 and the outside air. At this time, the container body 4
The water pressure resistance of is set to 10 cm or more. Further, the container body 4 may be formed of a transparent or translucent member so that the stored amount of the deliquescent liquid 8 accumulated in the container body 4 can be easily confirmed visually. Polycarbonate, polyethylene terephthalate, or the like is used as the transparent member, and polypropylene or the like is used as the semitransparent member.

In this embodiment, the three-dimensional shape of the moisture-permeable portion is a dome shape such as a hemispherical shape, but the three-dimensional shape of the moisture-permeable portion is not limited to the dome shape.

By forming an uneven portion on the outer peripheral surface of the fixing member, the uneven portion prevents slippage,
Workability when screwing the fixing member to the container body is significantly improved.

Further, by disposing an O-ring-shaped packing member between the upper surface of the upper end convex portion of the container body and the partition member, the constitution is made to enhance the adhesion between the container body and the partition member. Good.
