JP6543523B2 - Dehumidifier and Dehumidifier Containing Bag for Replacement - Google Patents

Description

  The present invention relates to a dehumidifier, and more particularly to a replacement dehumidifier containing bag sized to be contained in the container of the dehumidifier and visualizing a replacement time.

  For dehumidification, add a water retention agent such as super absorbent polymer in addition to the deliquescent substance of the type that keeps the aqueous solution in the container using deliquescent property, and as dehumidification proceeds in the packaging bag It is generally known that the jelly type, the silica gel, which is regenerated by drying in the sun, and used repeatedly, and the type in which the aqueous solution is stored in the container is clogs in light of the respective features. The jelly type is used in the bottom of a box, push-in, sink, etc., and is used in clothes dance, drawers, etc., and the regeneration type is used for dehumidifying shoes and futons.

  Among these, those of the type in which the aqueous solution is stored in a container are deciduous dehumidifying agents such as calcium chloride dihydrate (which may be tetrahydrate or hexahydrate) or self-supporting shaped plastic The container is housed in the upper inside divided by the inner tray, and water is stored in the lower part of the container (tank-type dehumidifier), and the container is sized in consideration of the amount of water at the end of product use ing.

  In such a dehumidifier, a moisture-permeable, water-permeable sheet having a large number of micropores of 10 to several microns, also referred to as a microporous membrane, is attached to the opening of the container, and the dehumidifying agent absorbs moisture. While being able to be exhibited, the dehumidifying agent and the aqueous solution generated by absorbing the dehumidifying agent by falling over of the container do not spill out of the container. A moisture impermeable sheet is laminated and attached so as to cover the moisture permeable and water impermeable sheet so that the hygroscopic performance does not decrease during circulation before storage or during storage, and this is used during use. Only the moisture impermeable sheet is removed from the container.

  In the tank-type dehumidifier, the dehumidifying agent is held in the vicinity of the opening where the microporous membrane facing the outside air is disposed by dividing the plastic container by the inner tray, to thereby increase the dehumidifying efficiency. However, in such a tank-type dehumidifier, the deliquesed liquid passes through the inner plate and falls to the lower part of the container, and although the deliquescent liquid itself has dehumidifying efficacy, the distance to the microporous membrane becomes long, and the deliquescent liquid There is a problem that a buffer space for dehumidifying air outside the container is generated between the and the microporous membrane, and the dehumidifying efficiency is lowered.

  In the tank type dehumidifier, it is necessary to separate only the moisture impermeable sheet at the time of use and fix the moisture permeable impermeable sheet thereunder with different adhesive strength so as not to separate from the container, so that the manufacturing cost It is increasing. Furthermore, in order to secure shock resistance during distribution and storage, the container is made of plastic, but it is bulky and increases distribution costs and storage costs. Then, when all the dehumidifying agent is liquefied and becomes an aqueous solution at the bottom of the container, the water-impermeable sheet is broken to discard the accumulated aqueous solution, and the remaining container can not be reused. Because it is disposed of according to the waste disposal regulations, there are many wastes of resources.

  Therefore, the present applicant has proposed a package body and a dehumidifier capable of reducing the amount of dust and preventing a change before use of the dehumidifying agent while achieving cost reduction in Patent Document 1. The package according to the proposal forms a closed space by a non-air permeable sheet (non-moisture permeable sheet) for blocking the permeation of gas, and also forms an air permeable sheet (permeable non-permeable) that allows the permeation of gas in the enclosed space. It is the package body divided by the water-permeable sheet) into the accommodation space in which the dehumidifying agent was accommodated, and the opening space opened at the time of use. Further, the dehumidifier is configured to include the above-mentioned package body, a container body for housing the same, and a lid body covering the upper opening of the container body and having a vent.

  In such a package, the air-permeable sheet is folded in a V-shape into two in the inside of the bag made of the non-air-permeable sheet at the time of distribution and storage, and cut in the open space side of the package at the time of use. The air-permeable sheet that has been folded in half is opened by opening the package and opening the package, and the contained dehumidifying agent starts to come in contact with the external air to exhibit deliquescent. Then, the air-permeable sheet of the opened package is set on the lid while facing the inverted lid, and after the inverted container is fitted on the lid, the container is erected. Is designed to be completed as a dehumidifier.

  In the dehumidifier having the package proposed in Patent Document 1, since the container and the lid can be used repeatedly, waste of resources can be considerably eliminated. In addition, the package is less bulky than the plastic container at the time of distribution and storage, and has advantages in terms of distribution cost and storage cost.

  However, in a dehumidifier using such a package, there is a problem that the degree of dehumidification in use is unclear to the user, and replacement at a suitable timing tends to be missed.

Japanese Patent Application Laid-Open No. 2002-332072

  The present invention has been made in view of such conventional problems, and the problem is that waste of resources can be largely eliminated, while the cost during distribution and storage can be suppressed, and the dehumidification efficiency can be high. An object of the present invention is to provide a dehumidifier that can be maintained, and in use, the degree of dehumidification is very easy for the user to understand, and ensures replacement at an appropriate time.

The above-mentioned subject is bent and attached to the inner side of the above-mentioned bag so that the above-mentioned closed space may be divided into a content accommodation space and a space for opening of the above-mentioned closed space. A moisture-permeable, water-permeable sheet, a deliquescent dehumidifying agent contained in the content-accommodating space, and a guide attached to the outer surface of the moisture-impermeable sheet to monitor the water level of the accumulated aqueous solution A dehumidifier containing the dehumidifying agent containing bag and the dehumidifying agent containing bag, and the dehumidifier comprising the container which can recognize the guide from the outside.

  It is conceivable to further comprise a lid for keeping the dehumidifying agent holding bag open and in an open state. The container or lid in the dehumidifier according to the present invention is assumed to reuse the container or lid of the used dehumidifier.

  The dehumidifying agent storage bag used in the dehumidifier according to the present invention further includes a lid forming piece attached to the outer surface of the moisture impermeable sheet, and the lid forming piece pulls the opened bag body open It is further preferable to form a lid capable of covering the moisture-permeable sheet that spreads at the same time, and to have a plurality of openings.

According to the present invention, the guide portion attached to the outer surface of the dehumidifying agent storage bag and capable of monitoring the water level of the accumulated aqueous solution can be recognized from the outside of the container for storing the dehumidifying agent storage bag, When using the dehumidifier, it is very easy for the user to understand the degree of dehumidification, and it is possible to reliably replace the dehumidifying agent storage bag at an appropriate time.

  Further, by reusing the container of the dehumidifier, not only waste of resources can be largely eliminated, but only the dehumidifying agent storage bag can be used at the time of distribution and storage, so that the cost thereof can be suppressed. Furthermore, when the dehumidifying agent storage bag is stored in the container, the dehumidifying agent is placed in contact with the moisture-permeable and water-permeable sheet, whereby the drop in the moisture absorption rate with time is extremely small, resulting in high dehumidifying efficiency. It can be maintained.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the dehumidifying agent storage bag according to the first embodiment in a state before use.

First Embodiment
The flat bag-like bag body 1 constituting the dehumidifying agent-containing bag is formed by overlapping the pair of rectangular moisture impermeable sheets 11 and bonding their peripheral portions to each other. By joining the peripheral portions of the superposed moisture impermeable sheets, the bag body is closed, and the inside becomes a sealed space 12 in which the flow of air is shut off. It is also possible to form a bag body by folding one non-moisture-permeable sheet in the center in the longitudinal direction and bonding the peripheral edge portions thereof instead of stacking the two non-moisture-permeable sheets. is there. Bonding may be performed using a suitable adhesive, but usually heat welding is preferably employed.

  Further, in the vicinity of the side to be opened of the bag 1, the microporous film 13 as a moisture-permeable, water-permeable sheet that allows moisture to permeate is folded in two between the two moisture-impermeable sheets. The peripheral edge portion of the microporous film 13 which is intervened and which is folded in half is fixed to the inside of the bag body 1 by heat welding, that is, to the inner surface side of the moisture impermeable sheet 11. It is also possible to use an adhesive instead of heat welding.

  By this microporous film 13, the inside of the bag body which is the sealed space 12 is divided into the content storage space 121 and the opening space 122, and the content storage space 121 absorbs moisture in the air. A predetermined amount of granular dehumidifying agent (for example, calcium chloride; optionally a water retention agent may be added) 14 is contained. Since the microporous film 13 is folded in two, when the opening space portion 122 is opened, the microporous film 13 spreads and becomes a large area when the bag 1 is pulled in the lateral direction, and high moisture absorption efficiency is obtained. Can be secured.

  Here, as a material of the film-like non-moisture-permeable sheet 11 which forms the bag 1, the film which coated the vinylidene chloride resin on the film of nylon or polyester, or these can be mentioned, for example. Moreover, as a material of the moisture-permeable, water-impermeable sheet or the microporous film 13, a film in which a large number of micropores of 10 to several microns are opened in polyethylene, polypropylene or the like can be mentioned.

Further, the volume of the content storage space 121 of the bag 1 needs to be set so as to be equal to or greater than the volume of the aqueous solution of the dehumidifying agent in a saturated state with almost complete dehumidification by the dehumidifying agent 14. Here, as described in JP-A-2002-332072, the case of using calcium chloride dihydrate as the dehumidifying agent will be described as an example. Calcium chloride dihydrate is known to absorb 2.84 times the water content under general use conditions, and the volume equivalent (ml) at that time is
Calcium chloride dihydrate weight (g) × (0.42 + 2.84) ml
It becomes. 0.42 is the volume increase rate when calcium chloride dihydrate is dissolved in water. This is a value obtained by dissolving a fixed amount of calcium chloride dihydrate in water and calculating the increase volume, which is the ratio of weight to volume, so that a practical specific gravity can be derived from this (2.38 g / ml = The reciprocal of 0.42). That is, assuming that the volume (ml) of the content storage space 121 of the bag 1 is about 7 to 10 times the value obtained by dividing the weight of the dehumidifying agent stored in the content storage space 121 by this specific gravity 2.38, Effective use of the bag 1 is possible. On the other hand, it is essential that the volume of the content storage space 121 is smaller than the volume of the container in which the bag 1 is stored. For example, when the bag 1 is accommodated in a 400 ml container and used as a dehumidifier, the content accommodation space 121 preferably has a volume of about 300 to 350 ml, and accordingly, the content accommodation space 121 is accommodated. The weight of the dehumidifying agent is preferably about 80 to 100 g.

  Also, on each outer side surface of the non-moisture permeable sheet 11 that has been bonded, a laterally oriented strip-shaped guide piece 15 that is a guide portion is attached. In some cases, it is sufficient to paste the guide piece 15 to either of the outer side surfaces. For example, the guide piece 15 made of paper board or plastic plate and having a certain degree of rigidity is colored in a color different from that of the bag 1 so that the bag 1 can be easily seen from the outside through the container when the bag 1 is accommodated in the container. It is done. If the attachment position of the guide piece 15 to the moisture impermeable sheet 11 is a portion corresponding to the boundary between the content storage space 121 partitioned by the microporous film 13 and the opening space 122, the guide piece It is easy to recognize itself as the water level position. If the upper side of the guide piece 15 is positioned so as to substantially coincide with the upper side of the microporous film 13 fixed on the inner surface side of the moisture impermeable sheet 11, the bag 1 is accommodated in the dehumidifier container and used. When the upper side of the bag body 1 approaches the upper lid of the dehumidifier container, the user can change the bag body 1 without delay knowing that the dehumidification is completed. In the illustrated example, the lateral length of the guide piece 15 is set smaller than the width of the container when the bag body 1 is accommodated in the container, but if there is no problem in the operation at the start of use, the longer Is preferred.

  Next, a mode in the case of using the flat bag-like bag body 1 which accommodates the granular dehumidifying agent 14 of predetermined amount and sticks the guide piece 15 on the outer side as a dehumidifier is demonstrated. First, as shown by the broken line in FIG. 1, the upper portion of the bag 1 is cut with scissors or the like to open the opening space 122. Under the present circumstances, since the content accommodation space 121 which accommodated the granular dehumidifying agent 14 is isolate | separated from the space part 122 for opening by the microporous film 13, the dehumidifying agent 14 is not in the state which open | released the space part 122 for opening. It is prevented from being scattered in preparation. And since this microporous film 13 allows permeation of air, the content storage space 121 comes into contact with the outside air through the microporous film 13 so that the dehumidifying agent 14 can absorb moisture in the atmosphere. Become.

  At the same time, prepare a dehumidifier container. The container is entirely or partially configured to be transparent or translucent so that the inside can be seen through. This can, for example, reuse the plastic container of the used dehumidifier, as shown in FIG. 2a. Break the microporous film (white moisture permeable membrane) from the used dehumidifier with scissors etc., discard the accumulated liquid (calcium chloride aqueous solution), and also remove the microporous film from the plastic container.

  Pull open the opened part of the bag body 1 cut with scissors in the lateral direction. At this time, the microporous film 13 which has been folded in half also spreads, and the film area that influences the moisture absorption efficiency is increased. As shown in FIG. 2 b, when the opening is on the side of the microporous film 13, the dehumidifying agent 14 contained in the bag 1 gathers on the lower side so as to contact the microporous film 13. At that time, the rigidity of the guide piece 15 is used to adjust the shape of the bag 1.

  As shown in FIG. 2c, the plastic container 21 prepared above is placed over the bag 1 thus turned upside down and turned over. The bag 1 is inverted, and the dehumidifying agent 14 to be stored falls to the side of the microporous film 13, and the remaining part of the bag 1 is devoid of the dehumidifying agent 14, so that part can be folded firmly For example, the folded portion of the bag 1 is properly fitted to the bottom side of the covered container 21.

  A lid 22 having an opening may be disposed on the microporous film 13 which can be recognized from the opening of the erected container 21 in order to keep the opened state of the bag 1 (FIG. 2 d). It is also possible to attach an upper lid, which is also used in the used dehumidifier, at the opening of the container. After folding the portion of the bag 1 where the dehumidifying agent does not exist and covering the plastic container 21, the container 21 is erected, and the bag 1 is positioned on the bottom side of the container 21 and attached to the outer surface of the bag 1. The guide piece 15 is positioned at a moderate height within the container (FIGS. 3a1, a2). At this time, the bag body 1 can be reliably positioned on the bottom side in the container by pushing the lid into the opening of the opened bag body.

  As dehumidification proceeds and the dehumidifying agent 14 absorbs external air through the microporous film 13, the dehumidifying agent condenses and accumulates in the bag 1, and as the internal volume of the bag increases, the water pressure in the bag increases. The bag portion folded at the bottom of the container is gradually released, and the guide piece 15 is gradually raised, and it is easy for the user to recognize the progress of dehumidification from the outside of the container (FIGS. 3b1, b2) . Also at this stage, the dehumidifying agent 14 or the deliquescent liquid and the microporous film 13 maintain the state of proximity as in the initial stage of moisture absorption. Even in the final stage of dehumidification (Fig. 2e, Figs. 3c1 and c2), the dehumidifying agent 14 and the deliquescent liquid and the microporous film 13 are always in contact with each other, and the moisture absorption speed like a conventional tank type dehumidifier having a buffer space. In the dehumidifier of this example, the water level of the aqueous solution accumulated from the side of the container 21 can be monitored by the guide piece 15.

  In this example, the attachment position of the guide piece 15 to the moisture impermeable sheet 11 is described as a portion corresponding to the boundary between the content storage space partitioned by the microporous film 13 and the opening space portion. However, if the guide piece 15 is to be used purely as an indicator for displaying the bag replacement time, as shown in FIG. 4, the container side is marked with the dehumidifier use end (eg "end" If the guide piece 15 'attached to the outside of the bag 1 overlaps this line (Figs. 4c1 and c2), the use of the dehumidifier ends, that is, even if it is time to replace the bag 1. Good.

  FIG. 5 shows the results of testing the state of moisture absorption over time with the dehumidifier according to the present invention and the conventional tank type dehumidifier in the same container volume. In the conventional product, the deliquesed liquid passes through the inner plate and falls to the lower part of the container, and a buffer space for dehumidifying the air outside the container is generated between the deliquescent liquid and the microporous membrane, and the dehumidification efficiency decreases. On the other hand, in the invention, even if dehumidification progresses, the dehumidifying agent or the deliquescent liquid and the microporous membrane are always in contact with each other, and the decrease in moisture absorption speed is extremely small, and as a result, the dehumidification efficiency can be maintained high.

Second Embodiment
FIG. 6 shows a dehumidifying agent storage bag according to a second embodiment, which corresponds to FIG. The same components as those of the first embodiment are given the same reference numerals and explanation thereof is omitted, and only different points will be described. In addition, in FIG. 6b, the depiction of the granular dehumidifying agent 14 of the central region in the content accommodation space is omitted in order to clarify the figure.

  Although a lid 22 as described in the first embodiment may be separately prepared, it is also conceivable that a suitable lid is not at hand of the user. Therefore, the lid forming piece 16 is attached by utilizing the area below the portion where the horizontally oriented strip-like guide piece 15 is attached on the outer surface of one side of the non-moisture permeable sheet 11 attached. The lid forming piece 16 is shown as a square in this example, and is provided with a hanging piece around it so as to be inserted into the upper opening of the dehumidifying agent storage bag as a lid, but the lid forming piece 16 is dehumidified. It should be in a shape that can open the agent storage bag and pull it apart in the lateral direction to appropriately cover the spread microporous film 13. Further, in the region forming the lid surface of the lid forming piece 16, a plurality of openings 17 (an example shown in the drawings so that the dehumidifying agent stored in the content storage space can contact the outside air to perform a sufficient dehumidifying function There are eight). When actually used as a dehumidifier, the lid forming piece 16 is removed from the bag 1. The lid forming piece 16 is fitted as a lid so as to cover the opened portion of the dehumidifying agent storage bag, and the contact between the outside air and the dehumidifying agent is secured through the opening 17.
