Description

Technical Field

[0001] The invention relates to a dehumidifier and a container thereof, which uses a deliquescent moisture absorbent to absorb moisture in the air to reduce the humidity of a space and maintain low humidity, and is used in a closet, a drawer cabinet, a shoe cabinet, other storage spaces, and the like. Background Art

[0002] In the past, the mainstream of dehumidifiers was the so-called tank-type dehumidifier, which is formed by sandwiching a receiving tray at a middle-high position in a container having an upper surface opening, thereby dividing the container into an upper space and a lower space, and storing a granular deliquescent hygroscopic agent in the upper space, and storing a deliquescent liquid of the deliquescent hygroscopic agent dripping from the dripping hole of the receiving tray in the lower space. The tank-type dehumidifier is constructed as follows: in order to prevent the deliquescent liquid from overflowing when it is accidentally overturned, a moisture-permeable film that does not pass liquid but passes gas is bonded or welded to the upper surface opening to seal the opening. In addition, in order to improve the moisture absorption performance of the dehumidifier, it is important to ensure that the contact area between the deliquescent hygroscopic agent and the air is large, so the receiving tray is generally set to a shape with a multi-stage protrusion, and the granular deliquescent hygroscopic agent is stored in the upper space formed in this way (Patent Document 1).

[0003] Prior art literature Patent Literature Patent Document 1: Japanese Patent Application Publication No. 2011-78865 Summary of the invention

[0004] Technical issues like Fig. 9 As shown in FIG. 1 , the tank dehumidifier described in Patent Document 1 is configured to include: a container body 4 having an upper surface opening; a grating-shaped receiving plate 5 built into the middle and high part of the container body 4 and dividing the container body 4 into an upper space N and a lower space M; and a moisture-permeable and water-impermeable moisture-permeable film 6 and a sealing sheet 7 that close the upper surface opening. The tank dehumidifier is provided with a cover 8 that can be detachably mounted on the upper surface opening of the container body 4 and protects the moisture-permeable film 6 and the sealing sheet 7. The tank dehumidifier thus configured contains a granular deliquescent desiccant C in the upper space N in the container body 4. When used by a consumer (user), the sealing sheet 7 is peeled off from above the moisture-permeable film 6, and moisture in the air flows into the container body 4 through the moisture-permeable film 6 and is absorbed by the deliquescent desiccant. When the deliquescent moisture absorbent is deliquesced and completely used up, the moisture-permeable film 6 and the like adhered to the upper surface opening are peeled off, the accumulated deliquescent liquid is poured out, and the container is discarded.

[0005] Therefore, since the used tank dehumidifier needs to be replaced with a new dehumidifier together with the container, it causes high costs and waste of resources. In addition, this is not only a problem of cost and waste of resources, but also a problem that it is very troublesome for consumers to purchase and carry bulky goods, or that the storage place for inventory goods requires space. As mentioned above, considering the required specifications for ensuring the contact area between the deliquescent desiccants and the air, the container will naturally become larger. In addition to the volume of the upper space and the lower space, air equivalent to the volume of the space equipped with multi-stage protrusions is also transported or stored. Furthermore, this is not only a more serious problem for consumers, but also a more serious problem for manufacturers, wholesalers, and retailers. This is because the transportation or storage of goods is forced to ensure large transportation capacity and space, thereby forcing companies to bear huge transportation costs and storage costs.

[0006] On the other hand, we have been hearing about companies working on topics such as sustainability for a long time, so their trends in developing sustainable materials and establishing mechanisms to avoid wasting resources have been attracting much attention.

[0007] The present invention aims to solve the above problems and has an object to provide a dehumidifier and a container thereof that can significantly reduce the amount of plastics and the like used while keeping the transportation cost and storage cost in mind.

[0008] Technical Solution A dehumidifier which uses a dehumidifying sheet and a special container in combination. The dehumidifier is characterized in that the dehumidifying sheet is a deliquescent absorbent in which a deliquescent substance is pressurized and compressed, and the special container comprises a deliquescent liquid storage container, a cover and a dehumidifying sheet mounting rack. The deliquescent liquid storage container has a snap-fitting portion for arranging the dehumidifying sheet mounting rack at a predetermined height from an inner bottom surface and is capable of storing the deliquescent liquid of the dehumidifying sheet. The cover ensures a firm connection with the deliquescent liquid storage container when it is clamped on the dehumidifying sheet mounting rack. The cover has an opening on the upper surface, and the opening is sealed by a moisture-permeable film. The dehumidifying sheet mounting rack has a hole at least at the bottom for allowing the deliquescent liquid of the dehumidifying sheet to flow downward into the deliquescent liquid storage container. The present invention solves the problem through the dehumidifier.

[0009] Technical Effects According to the present invention having the above-mentioned features, it is possible to provide a dehumidifier that can significantly reduce the amount of plastics and the like used and can suppress transportation costs and storage costs because the container can be reused.

DETAILED DESCRIPTION

[0021] The following detailed description of the embodiments of the present invention is based on the accompanying drawings, but the following drawings are made for the purpose of explanation, and unnecessary parts in the description may be intentionally omitted for ease of understanding. In addition, for ease of explanation, parts may be intentionally enlarged or reduced for illustration, and the drawings do not represent accurate scales.

[0022] <First embodiment> (Overall structure of dehumidifier) Figure 1 is an explanatory diagram showing the overall structure of a dehumidifier according to a first embodiment of the present invention. Figure 1 (a) is a front view of the state where the dehumidifying sheet mounting rack is clamped in the deliquescent liquid storage container and the cover is installed. Figure 1 (b) is a top view of the same state. Figure 1 (c) is a top view with only the cover removed. Figure 1 (d) is a photo of a replacement dehumidifier sheet. Figure 1 (e) is a photograph showing a state where the dehumidifying sheet is placed in a container with the lid removed.

[0023] The dehumidifier of the first embodiment of the present invention is a dehumidifier using a replacement dehumidification sheet and a dedicated container in combination. The replacement dehumidification sheet T is a deliquescent absorbent in which the deliquescent substance is pressurized and compressed, specifically calcium chloride in the form of tablets. Powdered calcium chloride is filled into the inner side of the cylinder of a 50t press (tablet press) and extruded by pressing, thereby manufacturing. The tableted calcium chloride can achieve a density of 1.63g / ml simply by adjusting the pressure, ensuring sufficient strength for actual use. It should be noted that magnesium chloride tablets can be used as a substitute for calcium chloride. As Figure 1 As shown in (d), the replacement dehumidifying sheet T is stored in an airtight transparent bag during storage. In order to prevent the deliquescence of the hygroscopic agent from progressing, the bag is a transparent bag with water vapor barrier properties, such as stretched polypropylene or polyvinylidene chloride, but it can also be opaque. In addition, it can also be obtained by lamination processing such as laminating with polyethylene, etc. using nylon film, aluminum foil, aluminum vapor deposition, etc. Regarding the laminating method, four-sided lamination, three-sided lamination (hand-to-hand lamination), self-supporting bag, blister packaging, etc. can be appropriately used. Furthermore, as long as it has water vapor barrier properties, not only bags, but also boxes or cans can be used as storage containers.

[0024] like Figure 1 (a) to Figure 1 As shown in (c), the dedicated container includes a deliquescent liquid storage container 1, a lid 2, and a dehumidifying sheet mounting rack 3. The deliquescent liquid storage container 1 is configured to store the deliquescent liquid of the replacement dehumidifying sheet T. The lid 2 is firmly connected to the deliquescent liquid storage container 1 in a state of being sandwiched between the dehumidifying sheet mounting rack 3. Specifically, it is configured as a screw cap or a twist cap.

[0025] from Figure 1 The front view (a) shows the side of the lower part 11 of the main body and the side of the cover 22. Figure 1 The top view of (b) shows that the opening 212 (not shown) provided on the upper surface of the cover 2 is sealed by welding the moisture permeable film F. On the other hand, from the top view showing the state where the cover 2 is removed Figure 1 (c) shows that the dehumidifying sheet mounting rack 3 is provided with the flange 33 supported by the edge 13 (not shown) of the opening of the deliquescent liquid storage container 1. The flange 33 is supported by the edge 13 (not shown) and the dehumidifying sheet mounting rack 3 is provided at a predetermined height from the inner bottom surface of the deliquescent liquid storage container 1.

[0026] like Figure 1 As shown in (c), the bottom surface 31 of the dehumidifying sheet mounting frame 3 is provided with a bottom hole 311 for allowing the deliquesced liquid of the dehumidifying sheet T to flow downward into the deliquesced liquid storage container 1. In addition, since the replacement dehumidifying sheet T has a specific thickness, Figure 1As shown in (e), the upper surface of the replacement dehumidifying sheet T is located at a predetermined height from the inner bottom surface of the deliquescent liquid storage container 1.

[0027] (Composition of deliquescent liquid storage container) Figure 2 1 is an explanatory diagram showing a deliquescent liquid storage container in a dehumidifier according to a first embodiment of the present invention. Figure 2 (a) is a top view, Figure 2 (b) is the main view, Figure 2 (c) is to make Figure 2 (a) is a view from above when rotated 45 degrees. Figure 2 (d) is observed from the front Figure 2 Figure (c).

[0028] The deliquescent liquid storage container 1 is a container of a composite shape consisting of a main body lower portion 11 whose four sides are chamfered in a rectangular parallelepiped, and a main body upper portion 12 which is a cylindrical portion connected to the main body lower portion 11. With respect to the main body lower portion 11, when a dehumidifying sheet mounting rack 3 (not shown) is provided, the area separated by the lower surface of the dehumidifying sheet mounting rack 3 (not shown) has a volume sufficient to accommodate the deliquescent liquid generated when a replacement dehumidifying sheet T is completely deliquesced, and in the first embodiment, it is set to 550cc. Above the main body lower portion 11, the main body upper portion 12 which is a cylindrical portion is connected coaxially with the central axis of the main body lower portion 11, so that Figure 2 As shown in (a) of FIG. 1 , the upper surface of the main body lower portion 11 is arranged at four corners around the main body upper portion 12 .

[0029] The outer circumference of the main body upper portion 12 is formed with an outer thread portion 121 that is screwed with the inner thread portion 221 (not shown) of the cap 2. The thread is preferably a plurality of threads so that it can be opened and closed with a small number of rotations. In the first embodiment, two threads are used, but four threads may be used.

[0030] The edge 13 of the top of the main body upper portion 12 functions to support the flange 33 (not shown) of the dehumidifying sheet mounting frame 3 , whereby the dehumidifying sheet mounting frame 3 (not shown) is disposed at a predetermined height from the inner bottom surface of the deliquescent liquid storage container 1 .

[0031] Two triangular protrusions 122 and two bulges 123 are arranged at every 90 degrees near the boundary where the upper surface of the main body lower part 11 is connected to the main body upper part 12. Through the triangular protrusions 122 and the bulges 123, the operator will feel the torque resistance increase when the fastening operation of the cover 2 is nearly completed, and will feel the snapping feeling at the end, so that the operator can confirm that the cover has been accurately closed.

[0032] (Composition of the cover) Figure 31 is an explanatory diagram showing a cover in a dehumidifier according to a first embodiment of the present invention. Figure 3 (a) is a top view, Figure 3 (b) is Figure 3 The cover 2 is generally composed of a cover upper surface 21 and a cover side surface 22, and a circular opening 212 is provided at the center of the cover upper surface 21. Figure 3 As shown in (b), the peripheral edge 211 of the cover upper surface 21 is set to a position higher than the cover upper surface 21, and a moisture permeable film F is heat-welded to the peripheral edge 211 (refer to Figure 1 ). In addition, the hanging edge 222 hangs downward from the outer periphery of the opening 212, and is set to a size that abuts against the upper surface of the flange 33 (not shown) of the dehumidifying sheet mounting frame 3 when the cover 2 is mounted on the deliquescent liquid storage container 1 (not shown). That is, there is a certain gap between the cover upper surface 21 and the flange 33 (not shown).

[0033] The dedicated container in the dehumidifier of the first embodiment is configured so that when the lid 2 is closed, liquid does not pass through the moisture permeable membrane F but gas passes through. Since the moisture permeable membrane F is arranged slightly away from the lid upper surface 21 by utilizing the height difference between the lid upper surface 21 and the peripheral edge 211, the area between the outer periphery of the opening 212 and the inner side of the peripheral edge 211 (i.e., in the area of ​​the opening 212) is not Figure 3 The area shown as the upper surface 21 of the cover in (a) also facilitates the passage of gas, thereby advantageously exerting the hygroscopic performance. The moisture permeable membrane needs to have the strength to withstand repeated use, and it is preferred to use a double-layer moisture permeable membrane formed by laminating a non-woven fabric on a porous membrane, wherein the porous membrane is formed by stretching polyethylene or polypropylene mixed with an inorganic filler. In addition, in order to have higher strength, it can also be a three-layer moisture permeable membrane formed by laminating a non-woven fabric, a porous membrane, and a non-woven fabric.

[0034] Since a general dehumidifier needs to overlap and attach a moisture-proof film on a moisture-permeable film, it is necessary to bond the moisture-proof film to the container. In addition, since the moisture-proof film needs to be peeled off when the dehumidifier is used, it is required that it can be easily peeled off without damaging the porous film layer.

[0035] If a moisture-proof film is directly overlapped and attached to a porous film formed by stretching polyethylene or polypropylene with an inorganic filler, it is difficult to easily peel off without damaging the porous film layer. In order to solve these problems, a moisture-permeable film formed by laminating a non-woven fabric on a porous film is mainly used. This is because the non-woven fabric can supplement the strength without hindering the moisture permeability of the porous film as much as possible. In addition, in order to facilitate the bonding with the container and the bonding with the moisture-proof film, the non-woven fabric also requires thermal welding properties.

[0036] Therefore, the fiber of the nonwoven fabric uses a sheath-core structure of PE and PET. In the first embodiment, since a moisture-proof film is not required, the nonwoven fabric (in the case of a three-layer structure, at least the nonwoven fabric on one side) does not need to be heat-welded, so a nonwoven fabric of PP or PET that is cheaper than an expensive sheath-core structure can be used.

[0037] An internal threaded portion 221 is formed on the inner periphery of the cover side 22 to be screwed with an external threaded portion 121 (not shown) formed on the outer periphery of the main body upper portion 12 of the deliquescent liquid storage container 1. The thread is preferably a plurality of threads so that it can be opened and closed with a small number of rotations. In the first embodiment, two threads are provided, but four threads may be provided. In addition, a cover in which a lug (claw) is provided on the inner periphery of the cover side 22 instead of the internal threaded portion 221 and is tightened around the external threaded portion 121, i.e., a so-called twist cover, may also be configured. As described above, the operator will feel that the torque resistance becomes larger when the tightening operation of the cover 2 is nearly completed, and will feel a snapping feeling at the end, so that it can be confirmed that the cover has been closed accurately. In addition, since the upper surface shape of the cover 2 is the same shape as the main body lower portion 11 (both not shown) of the deliquescent liquid storage container 1 (rectangular shape with chamfering), it is possible to confirm the completion of the cover closing from a visual point of view. That is, the operator only needs to confirm whether the shapes are aligned.

[0038] (Structure of the dehumidifying sheet mounting rack) Figure 4 1 is an explanatory diagram showing a dehumidifying sheet mounting rack in a dehumidifier according to a first embodiment of the present invention. Figure 4 (a) is a top view, Figure 4 (b) is a front view. The dehumidifying sheet mounting rack 3 includes a rack bottom surface 31, a rack side surface 32, and a flange portion 33. As an overall shape, Figure 4 As shown in (b), the frame bottom surface 31 is in a truncated cone shape that is smaller than the upper side where the flange portion 33 is located.

[0039] A bottom hole 311 is provided on the bottom surface 31 of the frame. The bottom hole 311 serves to allow the deliquescent liquid of the replacement dehumidifying sheet T to flow downward into the deliquescent liquid storage container 1. The bottom hole 311 is arranged such that a plurality of arc-shaped holes are located along a plurality of concentric circles arranged with different radii at predetermined intervals. Figure 4 As shown in (a), the innermost circumference is provided with four holes, followed by eight holes, and the outermost circumference is provided with twelve holes. It should be noted that the shape of the hole is not limited to an arc shape, and as long as the desired performance can be exerted, even if the deliquescent liquid flows downward, an appropriate shape can be adopted, for example, a long hole shape.

[0040] The side holes 321 are provided on the side surface 32 of the rack. The side holes 321 also help the deliquescent liquid of the dehumidifying sheet T to flow downward into the deliquescent liquid storage container 1. The side holes 321 are arranged in a manner that eight rectangular holes (the shape viewed from the front, to be precise, the shape in which the upper and lower sides of the rectangle are bent along the side surface of the rack) are located along the outer periphery of the side surface 32 of the rack at predetermined intervals. It should be noted that as for the shape of the hole, any appropriate shape can be adopted as long as the desired performance can be exerted, that is, the deliquescent liquid flows downward. In addition, if the performance of allowing the deliquescent liquid to flow downward sufficiently is exerted only by the bottom hole 311, the side holes 321 can be omitted. Regarding the downward flow of the deliquescent liquid, due to factors such as the frequency of recrystallization, its downward flow performance varies depending on the use environment, so for example, it can be considered to make the specifications different depending on the sales area.

[0041] The size of the edge 13 (not shown) of the opening of the deliquescent liquid storage container 1 is set to a predetermined height from the inner bottom surface of the deliquescent liquid storage container 1. The flange portion 33 of the dehumidifying sheet mounting frame 3 is also set to an appropriate size from the bottom surface of the dehumidifying sheet mounting frame 3. In addition, since the dehumidifying sheet T has an inherent thickness, the upper surface of the dehumidifying sheet T is located at a predetermined height from the inner bottom surface of the dehumidifying liquid storage container 1. As a result, the interval between the upper surface of the dehumidifying sheet T and the lower surface of the moisture permeable membrane F opposite thereto becomes close and roughly determined at the beginning of use. This interval is set to a closer interval than the distance between the moisture permeable membrane and the granular moisture absorbent in the previous tank dehumidifier by setting the size of the hanging edge 222 of the above-mentioned cover 2, thereby contributing to the moisture absorption performance. This content will be discussed later.

[0042] (How to use a dehumidifier) A method of using the dehumidifier according to the first embodiment of the present invention will be described.

[0043] (1) Prepare the dedicated container and the replacement dehumidifier sheet T in a transparent bag before use.

[0044] (2) The lid 2 attached to the deliquescent liquid storage container 1 is rotated in the cover opening direction and the lid 2 is removed. The dehumidifying sheet mounting rack 3 is pre-installed in the deliquescent liquid storage container 1 from which the lid 2 has been removed. If not, the flange portion 33 of the dehumidifying sheet mounting rack 3 is placed on the edge 13 of the deliquescent liquid storage container 1, thereby installing the dehumidifying sheet mounting rack 3 in the deliquescent liquid storage container 1.

[0045] (3) Open the replacement dehumidifier sheet T.

[0046] (4) The removed replacement dehumidifying sheet T is placed inside the dehumidifying sheet placement rack 3 .

[0047] (5) The lid 2 is rotated relative to the deliquescent liquid storage container 1 in the lid closing direction. Finally, when it is confirmed that the torque resistance becomes larger, a snapping feeling is felt, and the shape of the lid 2 overlaps with the shape of the main body lower portion 11 of the deliquescent liquid storage container 1, the lid is completely fastened.

[0048] (6) Install a dehumidifier in the space you want to dehumidify, such as a closet, chest of drawers, or shoe cabinet, to dehumidify the space.

[0049] (7) When the dehumidifying sheet T is completely deliquesced and the dehumidifying performance is reduced, the cover 2 and the dehumidifying sheet mounting rack 3 are removed, and the deliquescent liquid accumulated in the deliquescent liquid storage container 1 is poured out and discarded. In addition, the interior of the deliquescent liquid storage container 1 and the dehumidifying sheet mounting rack 3 are cleaned as needed.

[0050] (8) After that, the process can be returned to (2) above, and a new replacement dehumidification sheet T can be used for reuse.

[0051] (Dehumidifier's moisture absorption performance) As a result of investigation conducted by the inventors, it was found that desiccant sheets seem to be used overseas. However, there is currently no container for this purpose, and the desiccant sheets are simply placed in a suitable container via a sieve for use. As mentioned above, in order to improve the hygroscopic performance of the dehumidifier, it is necessary to ensure that the contact area between the deliquescent hygroscopic agent and the air is large, so there is a tendency to choose a granular hygroscopic agent. In fact, the same volume of granular hygroscopic agents and tablet hygroscopic agents were prepared, and experiments were conducted to confirm the difference in hygroscopic performance. It was found that there was a significant difference in hygroscopic performance. There is no need to explain that tablets are easy to handle, but overseas, most of the granular hygroscopic agents are used. After all, hygroscopic performance is still important.

[0052] Although it is explained that the dehumidification sheet is placed in a suitable container via a grating for use overseas, the suitable container does not have a moisture permeable but water-impermeable moisture permeable membrane. One of the purposes of using a moisture permeable membrane is to prevent the deliquescent liquid from overflowing into the drawer cabinet when the dehumidifier is accidentally overturned. Thus, the moisture permeable membrane is a unique structure of Japanese products that emphasize ease of use, but such consideration is not favored overseas.

[0053] The present inventors conducted experiments on the moisture absorption performance of the dehumidifier of the first embodiment of the present invention, that is, a dehumidifier in which the replaceable dehumidifying sheet T is placed in a dedicated container. Figure 5As shown, a comparative test was conducted on the relationship between the number of days that have passed and the amount of moisture absorbed when the first embodiment and the tank dehumidifier of the prior art example were placed in an atmosphere with a temperature of 25±2°C and a humidity of (80±5)%. The subject of the present invention is to significantly reduce the amount of plastic used and to suppress transportation costs and storage costs. The inventor originally thought that it would not matter if some moisture absorption performance was sacrificed, but the result was surprising. Figure 5 As shown, the first embodiment confirms that the moisture absorption performance of the tank dehumidifier is not inferior to that of the prior art example. The reason is considered to be as follows. When the deliquescing speed of "multiple granules" and "one dehumidifying sheet" is compared for the same weight and the same concentration of deliquescent substances without using a moisture permeable membrane, the granules with a large surface area are superior. However, it is speculated that the dehumidifier with a moisture permeable membrane determines the "flow rate of the amount of water vapor introduced into the container through the moisture permeable membrane" based on the "performance of the moisture permeable membrane", "the area of ​​the opening part of the cover and the upper part of the container", "the surface area of ​​the deliquescent substance", and "the distance between the deliquescent substance and the moisture permeable membrane" from its structure. This is because the first embodiment can easily adjust these parameters, and in particular, can set the distance between the deliquescent substance and the moisture permeable membrane to be accurately close.

[0054] As explained in the previous tank dehumidifier Fig. 9 As shown in the figure, in the upper space for storing the granular moisture absorbent, a certain amount of surplus space is formed between the granular moisture absorbent and the moisture permeable membrane. This is due to the requirement that the granular moisture absorbent is preferably not overfilled in order to ensure a large contact area. Originally, the present invention pursued compactness from the perspective of cost reduction, so the distance between the moisture permeable membrane and the replacement dehumidification sheet was set to be close, but this showed an unexpected effect.

[0055] <Second embodiment> The dehumidifier of the second embodiment of the present invention has the same point as the dehumidifier of the first embodiment in that it is a dehumidifier that uses a replacement dehumidification sheet and a dedicated container in combination, and uses a replacement dehumidification sheet T stored in a transparent bag having water vapor barrier properties and reuses the dedicated container. However, the second embodiment is different from the first embodiment in that two replacement dehumidification sheets T are used, and the size of the deliquescent liquid storage container 1A and the dehumidification sheet mounting rack 3A are increased for this purpose. Among them, regarding the cover 2, the same cover as the first embodiment is used.

[0056] (Composition of deliquescent liquid storage container) Figure 6 1 is an explanatory diagram showing a deliquescent liquid storage container in a dehumidifier according to a second embodiment of the present invention. Figure 6 (a) is a top view, Figure 6 (b) is the main view, Figure 6 (c) is to make Figure 6(a) is a view from above when rotated 45 degrees. Figure 6 (d) is observed from the front Figure 6 Figure (c).

[0057] The deliquescent liquid storage container 1A is a container of a composite shape, which is composed of a main body lower portion 11A whose four sides are chamfered and a main body upper portion 12A which is a cylindrical portion connected to the main body lower portion 11A. With respect to the main body lower portion 11A, when a dehumidifying sheet mounting rack 3A (not shown) is provided, the area separated by the lower surface of the dehumidifying sheet mounting rack 3A (not shown) has a volume sufficient to accommodate the deliquescent liquid generated when two dehumidifying sheets T are completely deliquesced, and in the second embodiment, it is set to 1000cc. Above the main body lower portion 11A, the main body upper portion 12A which is a cylindrical portion is connected coaxially with the central axis of the main body lower portion 11A, so that Figure 6 As shown in (a), the upper surface of the main body lower portion 11A is arranged at four corners around the main body upper portion 12A.

[0058] The outer periphery of the main body upper portion 12A is formed with an external thread portion 121A that is screwed with the internal thread portion 221 (not shown) of the cap 2. The thread is preferably a plurality of threads so that it can be opened and closed with a small number of rotations. In the second embodiment, two threads are used, but four threads may also be used.

[0059] The edge 13A at the top of the main body upper portion 12A functions to support a flange 33A (not shown) of the dehumidifying sheet mounting frame 3A. Thus, the dehumidifying sheet mounting frame 3A (not shown) is disposed at a predetermined height from the inner bottom surface of the deliquescent liquid storage container 1A.

[0060] Two triangular protrusions 122A and two bulges 123A are arranged at every 90 degrees near the boundary where the upper surface of the main body lower part 11A connects with the main body upper part 12A. Through the triangular protrusions 122A and the bulges 123A, the operator can feel the torque resistance increase when the fastening operation of the cover 2 is nearly completed, and can feel the snapping feeling at the end, so that the operator can confirm that the cover has been accurately closed.

[0061] (Configuration of the dehumidifying sheet mounting rack) Figure 7 1 is an explanatory diagram showing a dehumidifying sheet mounting rack in a dehumidifier according to a second embodiment of the present invention. Figure 7 (a) is a top view, Figure 7 (b) is a front view. The dehumidifying sheet mounting rack 3A includes a rack bottom surface 31A, a rack side surface 32A, and a flange portion 33A. As an overall shape, Figure 7 As shown in (b), the frame bottom surface 31A has a truncated cone shape that is smaller than the upper side where the flange portion 33A is located.

[0062] The bottom surface 31A of the frame is provided with a bottom hole 311A. The bottom hole 311A ​​functions to allow the deliquesced liquid of the dehumidifying sheet T to flow downward into the deliquesced liquid storage container 1A. The bottom hole 311A ​​is arranged such that a plurality of arc-shaped holes are located along a plurality of concentric circles arranged with different radii at predetermined intervals. Figure 7 As shown in (a), the innermost circumference is provided with four holes, followed by eight holes, and the outermost circumference is provided with twelve holes. It should be noted that the shape of the hole is not limited to an arc shape, and as long as the desired performance can be exerted, even if the deliquescent liquid flows downward, an appropriate shape can be adopted, for example, a long hole shape.

[0063] The side holes 321A are provided on the side surface 32A of the rack. The side holes 321A also help the deliquesced liquid of the dehumidifying sheet T to flow downward into the deliquesced liquid storage container 1. The side holes 321 are arranged in a manner that eight rectangular holes (a shape viewed from the front, to be precise, a shape in which the upper and lower sides of the rectangle are bent along the side surface of the rack) are located along the outer periphery of the side surface 32 of the rack at predetermined intervals. It should be noted that as the shape of the hole, any appropriate shape can be adopted as long as the desired performance can be exerted, that is, the deliquesced liquid flows downward. In addition, if the performance of allowing the deliquesced liquid to flow fully downward is exerted only by the bottom hole 311A, the side holes 321A can be omitted.

[0064] The size of the edge 13A (not shown) of the opening of the deliquescent liquid storage container 1A is set to a predetermined height from the inner bottom surface of the deliquescent liquid storage container 1A. The flange 33A of the dehumidifying sheet mounting rack 3A is set to an appropriate size from the bottom surface of the dehumidifying sheet mounting rack 3A. In addition, since the replacement dehumidifying sheet T has a specific thickness, the height (thickness) of the two replacement dehumidifying sheets T is a predetermined specific value, so the upper surface of the replacement dehumidifying sheet T is located at a predetermined height from the inner bottom surface of the deliquescent liquid storage container 1A. As a result, the interval between the upper surface of the replacement dehumidifying sheet T and the lower surface of the moisture permeable film F facing the upper surface thereof becomes a predetermined size. This interval is the same as that of the first embodiment, so the moisture absorption performance becomes good for the reasons described above. However, if the deliquescing of the amount of the two replacement dehumidifying sheets T progresses, the interval becomes larger than the interval when the deliquescing progresses in the first embodiment, so it is undeniable that it is slightly disadvantageous from the perspective of the deterioration of the moisture absorption performance over time. However, from the viewpoint of being able to extend the usage time, the second embodiment is more advantageous than the first embodiment.

[0065] (How to use a dehumidifier) The method of using the dehumidifier of the second embodiment of the present invention is not significantly different from the method of using the dehumidifier of the first embodiment. The only difference is that a replacement dehumidification sheet T containing two replacement dehumidification sheets T is prepared in a transparent bag. Of course, if it is not possible to prepare, two bags of replacement dehumidification sheets T containing one replacement dehumidification sheet T may be prepared. Two replacement dehumidification sheets T are placed, and the dehumidifier is reused in units of two by discarding the deliquescent liquid and the like of two dehumidification sheets.

[0066] (Dehumidifier's moisture absorption performance) like Figure 8 As shown, a comparative test was conducted on the relationship between the number of days that have passed and the amount of moisture absorbed when the tank dehumidifiers of the second embodiment and the prior art example were placed in an atmosphere with a temperature of 25±2°C and a humidity of (80±5)%. Figure 8 As shown, the second embodiment shows a result that slightly exceeds the moisture absorption performance of the tank dehumidifier of the prior art example.

[0067] In the above, the dehumidifier of the embodiment of the present invention is described in detail with reference to the accompanying drawings, and its structure is explained, but the specific structure is not limited to these embodiments, and design changes within the scope of the main purpose of the present invention are also included in the present invention. For example, the rectangular shape, which is a common shape of the deliquescent liquid storage container and the cover, can also be a circular shape. Although the function of visually confirming that the lid is closed will disappear, the operator can still feel that the operation is completed only through the increase in torque resistance generated by the triangular protrusion and the bulge and the feel brought by the snap feeling. Furthermore, whether it is a rectangular shape or a circular shape, if it is set as a twist cover method, the triangular protrusion or the bulge can also be omitted. This is because, originally, the twist cover completes the tightening of the cover while feeling the resistance through the lugs (claws) present on the inner periphery of the cover.

[0068] In an embodiment, the engaging portion for disposing the dehumidification sheet mounting rack is the edge of the upper surface of the deliquescent liquid storage container, and the dehumidification sheet mounting rack is a flange portion, but as long as the dehumidification sheet mounting rack can be accurately set at a predetermined height position, other engaging methods may be used, for example, a structure in which a recessed portion provided on the inner surface of the container engages with a convex portion provided on the dehumidification sheet mounting rack.

[0069] In the embodiment, the shape of the rack for mounting the dehumidifying sheet is a truncated cone, but may be a cylindrical shape. Similarly, from the viewpoint of efficiently storing in the middle rack, the replacement dehumidifying sheet T is preferably a truncated cone or a cylindrical shape, but may also be a sphere, and the shape is not particularly limited as long as it is stored in the middle rack. Considering the reasons explained in the item of hygroscopic performance of the dehumidifier, some hygroscopic performance may be sacrificed, but since the subject of the present invention is the reuse of resources, the suppression of transportation costs and storage costs, the reduction of hygroscopic performance does not deviate from the technical idea of ​​the present invention.

[0070] As described above, the size and shape of the bottom hole and the side hole can be of appropriate size and shape as long as they can play the desired function, but different types can also be prepared for summer and winter and spring and autumn, and replaced according to the season. In the season with large temperature difference (cold and hot difference), the hole is easily blocked due to recrystallization, so it is advantageous to use a hole with a large size. As an opposite conception, as long as it is used in the season where recrystallization is not easy to occur, the bottom hole can also be set to a small size that does not allow the granular desiccant to pass through, and the granular type can be used as a replacement desiccant, so as to make a container for both the dehumidification sheet type and the granular type. It should be noted that compared with the previous requirement to peel off the moisture permeable film and discard it together with the container, it is helpful to reduce costs only from the perspective of being able to reuse without discarding the container. In this way, from the perspective of the invention of the dehumidifier container, even if a granular desiccant is used, it does not deviate from the technical idea of ​​the present invention.
