Abstract
Description
[Technical field]
[0001] The present invention relates to a dehumidifier. [Background technology]
[0002] Conventionally, dehumidifiers that use hygroscopic chemicals as dehumidifiers have been available as easy-to-use dehumidifiers for use in ordinary households. Most dehumidifiers are configured by storing granular dehumidifiers such as calcium chloride in a container body and sealing the upper opening of the container body with a moisture-permeable sheet. In such dehumidifiers, in order to improve moisture absorption efficiency, a configuration has been proposed in which the desiccant is contained in the upper part of the container body near the upper opening, and the deliquescent liquid produced by the moisture absorption of the desiccant is contained in the lower part of the container body.
[0003] In addition, a configuration has been proposed in which at least a portion of the lower part of the container body is made transparent so that the surface position (liquid volume) of the deliquescent liquid can be visually confirmed, and a liquid indicator is provided on the inner wall of the transparent part that changes color when deliquescent liquid adheres to it (see Patent Document 1). This liquid indicator is formed by laminating a porous layer, which is opaque when it does not absorb liquid and becomes transparent when it absorbs liquid, and a colored layer on a support. When the porous layer absorbs liquid and changes from white and opaque to colorless and transparent, the color of the colored layer can be visually recognized. This allows the surface position of the stored deliquescent liquid to be visually recognized. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2011-092916 A Summary of the Invention [Problem to be solved by the invention]
[0005] However, if the deliquescent liquid flowing down from above or the stored deliquescent liquid comes into contact with the liquid indicator for some reason, the color of the colored layer becomes visible. Therefore, in such a dehumidifier, it is sometimes difficult to know the exact amount of the stored deliquescent liquid and to determine when it needs to be replaced. In view of the above circumstances, the present invention provides a dehumidifier that is simple in configuration and allows the time for replacement to be determined. [Means for solving the problem]
[0006] According to one aspect of the present invention, there is provided a dehumidifier comprising a container body having an opening at the top, a moisture permeable sheet attached to the container body so as to cover the opening, a tray disposed midway in the height direction within the container body and having a plurality of through holes, a desiccant disposed on the tray, and a coloring solution disposed within the container body, the coloring solution containing an organic solvent that can be unevenly distributed on the surface of water stored in the container body due to the action of the desiccant and a dye dissolved or dispersed in the organic solvent.
[0007] According to this aspect, it is possible to determine the time to replace the dehumidifier with a simple configuration. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. Various characteristic features shown in the following embodiments can be combined with each other.
[0010] Fig. 1 is a plan view showing a state in which a moisture permeable sheet has been peeled off from a container body in a dehumidifier according to this embodiment. Fig. 2 is a plan view showing a state in which a dehumidifier and a container have been removed from the dehumidifier in the state shown in Fig. 1. Fig. 3 is a plan view of the container body. Fig. 4 is a side view of the container body as viewed from the longitudinal direction. Fig. 5 is a side view of the container body as viewed from the lateral direction. Fig. 6 is a plan view of a tray. Fig. 7 is a side view of the tray as viewed from the lateral direction. In the following description, in Fig. 1 to Fig. 3 and Fig. 6, the front side of the paper is referred to as "top" or "upper" and the back side of the paper is referred to as "bottom" or "lower". Also, in Fig. 4, Fig. 5 and Fig. 7, the top front side is referred to as "top" or "upper" and the bottom side is referred to as "bottom" or "lower".
[0011] The dehumidifier 1 shown in FIG. 1 includes a container body 2, a moisture permeable sheet 3, a tray 4, a dehumidifying agent 5, and a container 7 that contains a coloring solution 6. <Container body 2> The container body 2 is, for example, a box-shaped molded product made of a resin material by injection molding. 3, the container body 2 has a bottom surface portion 21 having a substantially rectangular shape in a plan view, and side wall portions 22, 23, 24, and 25 provided upright from four sides of the bottom surface portion 21. That is, the container body 2 has an opening 20 that opens upward. As shown in FIGS. 4 and 5, each of the side walls 22 to 25 widens in a tapered shape from the bottom surface portion 21 upward.
[0012] At the boundary between the adjacent side walls 22 to 25, a step 26 protruding inward is formed to a predetermined height continuing toward the bottom surface 21. In addition, a rib 261 for reinforcing each step 26 is integrally formed along the height direction. A step 27 that protrudes inward is formed at the center of the pair of opposing side wall portions 24, 25 in the lateral direction (longitudinal direction), and continues to the bottom surface portion 21 side up to a predetermined height. By placing the outer periphery of the tray 4 on these steps 26 , 27 , the tray 4 is supported by the container body 2 .
[0013] The material of the container body 2 is not particularly limited, but examples thereof include polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polymethyl methacrylate, polyacrylate, polystyrene, polycarbonate, and ABS resin. Furthermore, the container body 2 can be colorless transparent, colored transparent, colorless translucent, or colored translucent. Coloring the container body 2 is useful for identifying the type of dehumidifier 1 (such as with charcoal, for a specific user, etc.). As will be described later, it is also possible to emphasize the contrast with the colored solution 6 present on the surface of the deliquescent liquid. The shape of the bottom surface portion 21 is not limited to a substantially rectangular shape, but may be, for example, a circle, an ellipse, or a polygon (for example, a substantially triangular, substantially square, or substantially hexagonal shape).
[0014] <Breathable sheet 3> The moisture permeable sheet 3 is attached to the container body 2 so as to close the opening 20 by, for example, bonding with an adhesive, fusion (ultrasonic fusion, high frequency fusion, heat fusion), or the like. This moisture permeable sheet 3 has a function of allowing gas to pass through but preventing liquid from passing through. A sheet having fine pores is preferably used as the moisture permeable sheet 3. The diameter of the fine pores is not particularly limited, but is preferably about 10 μm or less. The moisture permeable sheet 3 is 3000g / m 2 ·10000g / m for more than 24 hours 2 It is preferable that the moisture permeability is less than 24 hours (40℃, 90% RH). An example of such a sheet having fine pores is a stretched sheet containing inorganic particles. A specific example of the stretched sheet is a stretched sheet obtained by uniaxially or biaxially stretching a sheet formed of a resin composition containing a predetermined amount of inorganic particles in a thermoplastic resin such as polyolefin (polyethylene, polypropylene, etc.), polyvinyl chloride, polyester, or polyamide.
[0015] <Tray 4> The tray 4 is disposed midway in the height direction within the container body 2 and has a plurality of through holes 40 . The tray 4 is a plate-shaped molded product made of a resin material by injection molding, for example. The outer shape of the tray 4 is formed to correspond to the cross-sectional shape at the height of the container body 2 when placed on the steps 26 and 27. A protruding portion 41 that protrudes upward in a quadrangular pyramid shape is formed in the center of the tray 4, and a rectangular frame-shaped step portion 42 is formed on the outer periphery side of the protruding portion 41 of the tray 4. The protruding portion 41 and the step portion 42 also have through holes 40 on their side surfaces. The through-holes 40 are set to a size sufficient to prevent the desiccant 5 from passing through.
[0016] Further, on the tray 4, a plurality of ribs 43 for reinforcing the step portion 42 are arranged at predetermined intervals in the circumferential direction. The material of the tray 4 is not particularly limited, but the same resin materials as those exemplified as the material of the container body 2 can be used. The tray 4 can also be colorless transparent, colored transparent, colorless translucent, or colored translucent.
[0017] <Dehumidifier 5> The dehumidifying agent 5 is placed on the tray 4 . The constituent material of the dehumidifying agent 5 is not particularly limited, but examples thereof include calcium chloride, magnesium chloride, lithium chloride, etc. Among these, calcium chloride is preferable as the constituent material of the dehumidifying agent 5 because it is excellent in moisture absorption capacity, price, safety, etc. The desiccant 5 is preferably in a particulate form. In this case, the volume average particle size (D50) of the desiccant 5 is preferably about 0.5 mm or more and 10 mm or less, and more preferably about 1 mm or more and 5 mm or less.
[0018] <Container 7 containing coloring solution 6> The container 7 containing the coloring solution 6 is disposed in the space above the tray 4 in the container body 2 (above the dehumidifying agent 5 in this embodiment). According to this configuration, in assembling the dehumidifier 1, it is sufficient to place the container 7 on the desiccant 5 before attaching the moisture permeable sheet 3 to the container body 2, which makes it possible to preferably prevent the labor required for this assembly work from increasing significantly. The coloring solution 6 contains an organic solvent that may be unevenly distributed on the surface of the water (deliquescent liquid) stored in the container body 2 due to the action of the dehumidifying agent 5 (deliquescence of the dehumidifying agent), and a pigment dissolved or dispersed in this organic solvent. The container 7 is made of a water-soluble resin. Therefore, the container 7 gradually dissolves upon contact with the deliquescent liquid, releasing the colored solution 6 contained therein into the container body 2. As a result, the colored solution 6 is positioned on the surface of the deliquescent liquid, coloring the surface, making it possible to identify the surface position. This makes it easy to know when to replace the dehumidifier 1.
[0019] The specific gravity of the organic solvent at 15° C. is preferably about 0.7 to 0.9, and more preferably about 0.75 to 0.85. In this case, the colored solution 6 is more reliably positioned on the surface of the deliquescent liquid. In addition, it is preferable that the affinity of the organic solvent for the container body 2 is greater than its affinity for glass. This means that the organic solvent is poorly hydrophilic, and is easily compatible with the container body 2 made of the resin material described above. In this case, the colored solution 6 located on the surface of the deliquescent liquid (water) tends to gather near the inner surface of the container body 2 (see FIG. 8(a)), and the surface position of the deliquescent liquid can be recognized more accurately. The same is true for polyethylene terephthalate (PET) containers (see FIG. 8(b)). On the other hand, in the case of a glass container, the colored solution 6 located on the surface of the deliquescent liquid (water) gathers in the center of the glass container in a plan view (see FIG. 9). For this reason, it is difficult to recognize the surface position of the deliquescent liquid.
[0020] The degree of affinity of the organic solvent with the container body 2 can be expressed by the contact angle of the organic solvent with the container body 2. Specifically, the contact angle of the organic solvent with the container body 2 at 25°C is preferably about 5° or more and 30° or less, and more preferably about 10° or more and 25° or less. In this case, most of the colored solution 6 gathers near the inner surface of the container body 2, so that the surface position of the deliquescent liquid can be recognized more accurately with a relatively small amount of colored solution 6. As the organic solvent, a compound with low volatility that satisfies the above conditions is selected.Specific compounds include, for example, liquid paraffin, silicone oil, silicone derivatives, squalane oil, olive oil, safflower oil, soybean oil, camellia oil, corn oil, rapeseed oil, sunflower oil, cottonseed oil, peanut oil, avocado oil, camellia oil, jojoba oil, etc.These compounds may be used alone or in combination of two or more.Among these, liquid paraffin is preferred as the organic solvent.
[0021] The color of the dye preferably has a phase difference angle of 45° to 120°, more preferably 60° to 105°, with respect to the color of the container body 2 in the PCCS color wheel. In other words, the color of the dye and the color of the container body 2 preferably have a mid-contrast hue relationship in the PCCS color wheel. For example, if the color of the container body 2 is light blue, the color of the dye is selected to be yellow. Also, if the color of the container body 2 is red, the color of the dye is selected to be blue. In these cases, the surface position of the deliquescent liquid can be more clearly recognized. Examples of the dye include CI Solvent Yellow 33, CI Solvent Yellow 16, CI Acid Yellow 3, CI Disperse Yellow 64, CI Acid Yellow 1, CI Acid Orange 3, CI Disperse Yellow 42, CI Pad Blue 5, CI Basic Blue 3, and CI Basic Blue 9. In addition, the dye is preferably a compound that is easily soluble in an organic solvent, does not easily migrate into the deliquescent liquid (water), and is stable over time. From this viewpoint, CI Solvent Yellow 16 is suitable as the yellow dye.
[0022] The content of the dye in the coloring solution 6 is preferably about 0.01 g / L or more and 5 g / L or less, and more preferably about 0.1 g / L or more and 1 g / L or less. The coloring solution 6 containing the dye in such an amount is sufficiently and reliably colored, so that the surface position of the deliquescent liquid can be more reliably recognized. The amount of coloring solution 6 is determined based on the area of the inner surface of the container body 2 at the center in the height direction. 2 The amount of coloring solution 6 is preferably about 0.0005 mL or more and 5 mL or less, more preferably about 0.001 mL or more and 1 mL or less, and even more preferably about 0.005 mL or more and 0.5 mL or less per unit time. With such a relatively small amount of coloring solution 6, the surface of the deliquescent liquid can be sufficiently colored. The specific amount of the coloring solution 6 is preferably about 0.5 mL to 25 mL. The area of the region surrounded by the inner surface at the center in the height direction of the container body 2 (the water surface area of the deliquescent liquid at half the height of the container body 2) is preferably 50 cm 2 More than 100cm 2 It is set to the following extent. The capacity of the container body 2 is appropriately determined depending on the environment and purpose of use of the dehumidifier 1, and is therefore not particularly limited.3 More than 1500cm 3 It is preferable that the distance is less than 300 cm. 3 More than 1000cm 3 In the case of a type for home use, the capacity of the container body 2 is preferably about 550 cm 3 That's about it.
[0023] In this embodiment, the container 7 is a bag made by sealing the outer edge of a film 71 made of a water-soluble resin with a seal part 72. Such a bag is preferable because it has a simple structure and can be produced relatively easily. The container 7 can also be a capsule, a box, a shell, or the like. Examples of water-soluble resins include polyvinyl alcohol, polyvinylpyrrolidone, vinylpyrrolidone copolymers, sodium alginate, dextran, polyacrylic acid, sodium polyacrylate, sodium carboxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, etc. These compounds may be used alone or in combination of two or more.
[0024] In the above embodiment, the container 7 containing the colored solution 6 is arranged on the dehumidifying agent 5. In this case, the container 7 may be designed so that the water-soluble resin constituting the container 7 has low solubility in water, and the colored solution 6 may be released after a sufficient amount of deliquescent liquid is stored in the container body 2. This makes it possible to omit strict consideration of the effect of the colored solution 6 on the dehumidifying agent 5 (for example, whether the colored solution 6 covers the dehumidifying agent 5 and reduces the hygroscopicity of the dehumidifying agent 5, etc.). The container 7 containing the colored solution 6 may be disposed in a space below the tray 4 in the container body 2. In this case, for example, the container 7 may be fixed to the bottom surface of the tray 4, or to the bottom surface portion 21 or the side wall portions 22 to 25. In this case, the surface position of the deliquescent liquid can be visually confirmed from the early stage when the storage of the deliquescent liquid starts.
[0025] Furthermore, when the coloring solution 6 is placed in the space below the tray 4 inside the container body 2, it may be placed alone on the bottom surface portion 21 without being stored in the storage body 7. However, storing the coloring solution 6 in the storage body 7 improves the handleability of the coloring solution 6 and facilitates the assembly work of the dehumidifier 1. It also reduces the possibility that the coloring solution 6 will escape from the dehumidifier 1 during distribution and storage. Furthermore, even if the dye is somewhat unstable in the atmosphere, it is easier to suppress the alteration and deterioration of the dye during distribution and storage of the dehumidifier 1. Furthermore, the containers 7 containing the colored solutions 6 may be disposed in both the space above the tray 4 and the space below the tray 4 in the container body 2. In this case, at least one of the hue, saturation, and brightness of the two colored solutions 6 can be made different. This makes it possible to visually confirm the surface position of the deliquescent liquid from the early stage when the storage of the deliquescent liquid begins, for example, and to change the hue of the surface of the deliquescent liquid or the degree of coloring when the time to replace the dehumidifier 1 (maximum storage capacity of the deliquescent liquid) approaches. This makes it easier to know when to replace the dehumidifier 1.

[0037] The present invention will be described in more detail below using the following examples and comparative examples, but the present invention is not limited to the following examples.
[0038] 1. Preparation of a bag containing a coloring solution (Bag A containing colored solution A) First, 5 mg of CI Solvent Yellow 16 ("OIL YELLOW 3G" manufactured by Orient Chemical Industries Co., Ltd.) was dissolved in 10 mL of liquid paraffin ("Sumoil P-100" manufactured by MORESCO Corporation; specific gravity at 15°C: 0.85) to prepare colored solution A. Next, 2 mL of the coloring solution A was placed in a bag A made by heat sealing the outer edge of a 35 μm-thick water-soluble film (manufactured by Kuraray Co., Ltd., "Water-soluble Poval Film VF-H123") at the seal portion.
[0039] (Bag B containing coloring solution B) Bag B containing coloring solution B was prepared in the same manner as bag A containing coloring solution A, except that CI Solvent Yellow 33 (Yellow No. 204) was used instead of CI Solvent Yellow 16.
[0040] 2. Manufacturing of dehumidifiers Example 1 First, as shown in Figure 1, a tray was attached to a polypropylene container body (light blue) with a capacity of 550 mL, and approximately 200 g of calcium chloride particles (volume average particle size: 3 mm) was placed on the tray. Next, with the bag A containing the coloring solution A placed on the calcium chloride particles, a moisture-permeable sheet (moisture permeability 5000 g / m) was placed over the opening of the container body to close the opening. 2 The specimens were then heat-sealed for 24 hours. The amount of colored solution A is 1 cm2 of the area surrounded by the inner surface at the center of the height of the container body. 2 The volume was approximately 0.08 mL per unit volume. Furthermore, the color of CI Solvent Yellow 16 had a phase difference angle of 105° or more and 120° or less with respect to the color of the container body in the PCCS color wheel.
[0041] Example 2 A dehumidifier was manufactured in the same manner as in Example 1, except that bag B containing coloring solution B was used instead of bag A containing coloring solution A. The amount of colored solution B is 1 cm2 of the area surrounded by the inner surface at the center of the height of the container body. 2 The volume was approximately 0.08 mL per unit volume. Furthermore, the color of CI Solvent Yellow 33 had a phase difference angle of 90° or more and 105° or less with respect to the color of the container body in the PCCS color wheel. (Comparative Example) A dehumidifier was produced in the same manner as in Example 1, except that the bag A containing the coloring solution A was omitted.
[0042] 3. Moisture absorption test The dehumidifiers of each of the Examples and Comparative Examples were left in an environment of a temperature of 40° C. and a humidity of 90% RH for 50 days without any windscreen. The amount of deliquescent liquid retained was then measured on days 0, 8, 11, 13, 35, and 47 after the start of the test. The results are shown in Figure 10.
[0043] As shown in FIG. 10, no effect (reduction) of the colored solution on the moisture absorption speed of calcium chloride particles (dehumidifying agent) was observed. In the dehumidifiers of the Examples, the surface of the deliquesced liquid was colored by the colored solution, and the colored solution was collected near the inner surface of the container body, so that the surface of the deliquesced liquid could be visually confirmed even from outside the container body. In addition, colored solution A had higher stability over time and showed better color development. In contrast, in the dehumidifiers of the Comparative Examples, it was difficult to visually confirm the color from outside the container body. [Explanation of symbols]
