DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying container used for dehumidifying indoors and storages using a deliquescent agent, and more particularly to improving the hygroscopic performance and accumulating the deliquescent agent in a reservoir. Not related to dehumidifying containers.

[0002]

2. Description of the Related Art Conventionally, a dehumidifying container in which a deliquescent chemical is packed in a dehumidifying container and used for the purpose of dehumidifying the inside of a closet or a closet has been widely used. As such a dehumidifying container, for example, an inner space of a container body having a ventilation part closed with a water-impermeable moisture-permeable membrane is provided with a drip hole for deliquescent liquid.
It is divided into two upper and lower spaces by two trays, and a deliquescent agent such as calcium chloride or magnesium chloride in powder, granular or granular form is stored in the upper space, and atmospheric moisture is stored in the lower space. Various structures have been proposed and put into practical use, in which a deliquescent liquid of a deliquescent drug dehydrated by absorbing air containing water is dropped through the dropping hole and stored.

[0003] However, in a conventional dehumidifying container in which a deliquescent drug is stored in a dehumidifying container body having a ventilation part closed by a non-permeable moisture-permeable membrane, the distance between the non-permeable moisture-permeable membrane and the deliquescent drug is limited. There has been a problem that the moisture absorption rate is reduced by leaving.

In order to solve the problem, Japanese Utility Model Publication No. Sho 61-10743 discloses a high moisture absorbing agent which is filled in a porous bottom plate provided at the opening of a container, and has a high followability and is permeable to gas. There is shown a dehumidifier with a liquid leakage prevention film that is covered with a semi-permeable membrane that is impermeable to liquids, and that drip and absorb deliquescent liquid by dropping into a container through holes in a porous bottom plate.

According to this dehumidifier, since no space is formed between the desiccant and the semipermeable membrane, the moisture absorption efficiency is improved, and
Leakage of deliquescent liquid due to moisture absorption is prevented.

Japanese Utility Model Laid-Open Publication No. 2-70720 discloses a container main body whose upper opening is covered by a semipermeable membrane that allows gas to permeate but does not allow liquid to permeate. The storage part has a middle partition body vertically partitioned, and the middle partition body is constituted by a slanted partition part and a protruding part, a discharge passage hole is provided in the partition part, and an outside air vent is provided in the protrusion part. The provided dehumidification container is shown.

According to this dehumidifying container, when the absorbent is filled in a state where the outside air vent provided in the projecting portion of the partition is exposed, the distance between the semipermeable membrane and the upper portion of the projecting portion is set to approximately 1 cm. And the moisture absorption rate becomes faster.

[0008]

However, in the dehumidifier with a liquid leakage prevention film disclosed in Japanese Utility Model Publication No. 61-10743, the deliquescent liquid of the desiccant, which has been deliquescent by absorbing the air containing moisture in the atmosphere, is not yet obtained. The blocking effect occurs before the deliquescence of the hygroscopic agent, which is in contact with the hygroscopic agent that has not absorbed moisture, comes into contact with the semipermeable membrane and reaches the porous bottom plate and drops from the hole, causing The ability to absorb moisture could not be sufficiently exhibited. In addition, there is a problem that it is troublesome to attach the hygroscopic agent raised on the porous bottom plate to the semi-permeable membrane having high followability and cover the same.

In the dehumidifying container disclosed in Japanese Utility Model Application Laid-Open No. 2-70720, an intermediate partition is devised in order to reduce the distance between the semipermeable membrane and the moisture absorbent. Is set to about 1 cm in advance, there is a problem in that the moisture absorbent eventually deliquesces and the distance between the semipermeable membrane and the moisture absorbent is further expanded, and the moisture absorption rate is reduced.

Further, in a dehumidifier of the type having a storage portion at the lower part of the intermediate partition, the granular hygroscopic agent stored in the drug storage portion is powdered due to factors such as friction and falls into the storage portion to be deposited. A phenomenon occurred, giving the user an unpleasant impression that the amount of the hygroscopic agent had decreased.

The present invention has been made in view of the above circumstances, and when dehumidifying a room or a storage, the distance between the non-water-permeable moisture-permeable member and the deliquescent drug is always kept close to make the deliquescent drug available. It is an object of the present invention to provide a dehumidifying container in which moisture absorption performance is enhanced and a powdered deliquescent drug does not accumulate in a storage portion and deteriorate appearance.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view, a plan view, and a bottom view including a cross-sectional view illustrating a schematic configuration of a dehumidifying container according to an embodiment of the present invention.

As shown in FIGS. 1 (a), 1 (b) and 1 (c), a dehumidifying container 1 is provided with a granular deliquescent drug 2 such as calcium chloride.
Container body 3 provided with a medicine container 3a for accommodating water and a deliquescent liquid storage part (hereinafter abbreviated as storage part) 3b for storing the deliquescent liquid 2a deliquescent by absorbing air containing moisture by the deliquescent drug 2 And a medicine container 3 for accommodating the deliquescent medicine 2
and a non-water-permeable moisture-permeable member 5 which is a non-water-permeable moisture-permeable member that blocks the opening 4 of Fig. 1a and transmits the moisture-containing air but does not transmit the deliquescent liquid 2a.

The medicine container 3a provided in the container body 3
Has, for example, a rectangular parallelepiped shape, and has an opening 4
have. Then, the opening 4 of the medicine container 3a
For example, two reservoirs 3b, 3b are provided at positions opposing the lower peripheral edge of the medicine container 3a.

An elongate drain port 6 through which the deliquescent liquid 2a passes communicates with, for example, the storage section 3b formed in a concave shape at the outer peripheral edge of the medicine container section 3a on the opening 4 side.
Is provided. The size of the recess of the drainage port 6 is such that the deliquescent drug 2 which has been powdered due to the particles or friction of the deliquescent drug 2 before use does not fall from the drainage port 6 into the reservoir 3b. , The deliquescent liquid 2a passes smoothly and the reservoir 3
It is formed narrower in the range where it is dropped on b.

The water-impermeable and moisture-permeable membrane 5 is welded to the opening 4 of the medicine container 3a. The lower surface of the water-impermeable and moisture-permeable membrane 5 is accommodated in the medicine container 3a. For example, in order to prevent the water-impermeable and moisture-permeable membrane 5 from being broken by the weight of the deliquescent drug 2 or hanging down vertically, for example, a thin plate-shaped holding plate in which ventilation holes through which air passes are formed as a plurality of lattice holes 7a. 7.

The anti-water-impermeable and moisture-permeable membrane 5 of the holding plate 7
Before use, the lattice holes 7a are closed by a waterproof film (not shown) for preventing air from entering the medicine container 3a before use.

The operation of the dehumidifying container 1 configured as described above will be described. First, the waterproof film attached to the holding plate 7 is peeled off. Then, the air containing moisture passes through the lattice holes 7a of the holding plate 7 and the water-impermeable and moisture-permeable membrane 5 welded to the opening 4 of the container body 3, and enters the medicine container 3a. At this time, since the deliquescent drug 2 stored in the drug container 3a is placed on the water-impermeable and moisture-permeable membrane 5, the deliquescent drug 2 has entered the drug container 3a. Instantaneously comes into contact with the deliquescent drug 2 placed on the water-impermeable and moisture-permeable membrane 5.

When the deliquescent drug 2 comes into contact with air containing water, the moisture in the air is absorbed by the deliquescent drug 2 and becomes a deliquescent liquid 2a from the drainage port 6 to the storage part 3.
It is dropped and stored in b.

Even when the deliquescent drug 2 deliquesces and the deliquescent liquid 2a is stored in the storage part 3b and the deliquescent drug 2 in the drug storage part 3a is reduced, the deliquescent drug 2 is always kept.
Is placed on the water-impermeable and moisture-permeable membrane 5, the air containing water instantaneously comes into contact with the deliquescent drug 2 and deliquesces.

As described above, the opening of the medicine container is provided vertically below, and the water-permeable moisture-permeable membrane is welded to the opening, so that the air containing moisture that has passed through the water-impermeable moisture-permeable membrane is removed. Since it instantaneously comes into contact with the deliquescent drug placed on the water-impermeable and moisture-permeable membrane, the moisture-absorbing performance can be greatly improved.

Further, a drain port for discharging the deliquescent liquid of the deliquescent drug that has been absorbed and deliquescent by contact with air containing moisture is recessed from the outer peripheral edge of the opening to form an elongated recess. In addition, the deliquescent liquid can be smoothly dropped into the reservoir to prevent the deliquescent drug blocking phenomenon,
The deliquescent chemical powdered due to friction or the like can be prevented from dropping into the reservoir and accumulating. This eliminates discomfort during use, such as the blocking phenomenon and poor appearance of the drug accumulated in the reservoir.

Further, since the water-impermeable and moisture-permeable membrane welded to the vertically lower opening of the medicine container is held by the thin holding plate provided with the ventilation hole, the water-impermeable material is impermeable by the weight of the deliquescent medicine. It is possible to prevent the permeable moisture permeable membrane from being torn or hanging vertically downward.

Further, since a storage space serving as a storage part for storing the deliquescent liquid of the deliquescent drug is formed at the lower edge of the medicine storage part, the deliquescent liquid stored in the storage part and the medicine storage part are formed. Elution of the deliquescent drug can be prevented by contact with the stored deliquescent drug. This allows the deliquescent drug to be consumed efficiently.

As shown in FIG. 2, openings 4 are provided vertically below and vertically above the medicine container 3a, and the openings 4 provided above and below are closed with a water-impermeable and moisture-permeable membrane 5. Air containing moisture passes through the non-permeable moisture-permeable membrane 5 provided in the opening 4 on the upper surface and the opening 4 on the lower surface, so that the medicine container 3 a
Since it penetrates into the inside, the moisture absorption performance in the initial stage can be improved. At this time, in order to protect the water-impermeable and moisture-permeable membrane 5 welded to the opening 4 on the upper surface, the container lid 8 provided with a plurality of air intake holes 8a is covered.

Further, as shown in FIG.
Plate 7A which is disposed in the housing and holds the water-impermeable and moisture-permeable membrane 5
To the upper end 7 of the holding plate 7A located in the medicine container 3a.
b, the inclined surface 7c that is smoothly inclined toward the drain port 6.
For example, it is formed in a three-dimensional shape having an arch shape. As a result, the deliquescent liquid 2a deliquescent in the medicine container 3a is guided to the drainage port 6 along the inclined surface 7c and is dropped into the reservoir 3b, so that the deliquescent in the medicine container 3a is more efficiently performed. The liquid can be discharged to the reservoir 3b. The shape of the holding plate 7A is not limited to an arch shape, but may be a pyramid shape or a conical shape. Further, by making the holding plate 7A into an arch shape, the size and shape of the water-impermeable and moisture-permeable membrane 5 are adjusted according to the change in the surface area of the holding plate 7A. Further, the present invention is not limited to the configuration in which the holding plate is disposed on the lower surface of the non-water-permeable moisture-permeable member. The holding plate may be formed in a three-dimensional shape so that it can be placed, and the lower surface of the holding plate may be closed with a water-impermeable and moisture-permeable member. In this case, by providing the slit radially from the upper end of the solid body toward the storage chamber, it is possible to prevent the deliquescent liquid from accumulating in the slit and impairing the air permeability.

It is to be noted that, instead of disposing the arched holding plate 7A and the water-impermeable and moisture-permeable membrane 5 in the lower opening 4 shown in FIG. For example, an arch-shaped non-water-permeable moisture-permeable portion may be formed.
This makes the holding plate 7A unnecessary, and
The assemblability is greatly improved.

The shape of the medicine container and the location and shape of the deliquescent liquid reservoir are not limited to the rectangular parallelepiped shape shown in FIG. 1, but may be a column shape or the like.
