Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a novel dehumidifier. Specifically, it is a dehumidifier that can dehumidify a large area with high dehumidification capacity and can effectively prevent damage due to contact with an object.

[0002]

[Prior art]

 As a household dehumidifier, various dehumidifiers using a deliquescent desiccant such as calcium chloride have been proposed. These are a form in which a deliquescent desiccant is filled in a container whose upper surface is made of a breathable sheet, a form in which a mixture of a deliquescent desiccant and an absorbent powder is filled in a bag made of a breathable sheet, A form in which a deliquescent desiccant is supported on a plate-shaped liquid absorbent is known.

[0003]

[Problems to be solved by the device]

 On the other hand, as a dehumidifier for home use, for example, when dehumidifying by installing it between the futon in the closet or in the gap between the closet and the wall, or when installing it in a closet full of clothes. In some cases, the moisture in the limited gap may be removed.

In such an application, a dehumidifier in which a deliquescent desiccant is filled in a container whose upper surface is made of a breathable sheet can be installed only in a corner portion, and the device itself is not installed. A dehumidifier in which a mixture of a deliquescent desiccant and an absorbent powder is filled in a bag made of a breathable sheet is difficult, and a large area such as between futons or between a closet and a wall is required. Not only is it difficult to securely set the dehumidifier in the gap, but there is also a problem that the deliquescent desiccant exposed to the bag may cause contamination due to damage to the bag. In the case of a dehumidifier in which a deliquescent desiccant is loaded on a plate-shaped liquid absorbent, it is possible to set the dehumidifier in a large area gap, but the amount of the deliquescent desiccant impregnated is considerably low. Since it is limited by, the dehumidification amount is low and the dehumidification rate still has room for improvement.

[0005]

[Means for Solving the Problems]

 The present inventors have made earnest studies to develop a dehumidifier that is difficult to achieve with the above-mentioned conventionally proposed dehumidifier, is easy to install in a large area gap, and has excellent dehumidification ability. Overlaid. As a result, a unit dry bag in which a desiccant is filled in a bag made of a breathable sheet is constructed with a breathable sheet for protecting the unit dry bag on one side and a non-permeable sheet on the other side. A plurality of the unit dry bags are loaded in an arrayed inside bag, and the breathable sheet is installed on the side of the large holes in a flat hard case having one large hole dispersed therein. By loading so as to face, such an object was achieved and the present invention was proposed.

Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited to these accompanying drawings.

FIG. 1 is a schematic diagram showing a typical aspect of the present invention.

That is, the dehumidifier of the present invention comprises a flat hard case 1 having a plurality of coarse holes 2 dispersed on one surface, one surface made of a breathable protective sheet 3-a, and the other surface. It is composed of a middle bag 3 whose surface is made of a water impermeable sheet 3-b, and a unit dry bag 4 which is made by filling a flat bag made of a breathable sheet with a desiccant. A plurality of bags 3 are loaded in an array state, and the inner bag 3 is configured by loading a breathable protective sheet 3-a in the hard case 1 toward the coarse hole 2 side of the hard case. .

In the present invention, the material of the hard case 1 is not particularly limited as long as it can be installed while maintaining the flat shape in the gap. Typical examples of the material are paper such as corrugated cardboard and cardboard, and plastics such as polypropylene, polyethylene and polyvinyl chloride.

In order to secure a sufficient moisture absorption area without reducing the strength of the hard case, the hard case 1 is formed with coarse holes 2 dispersed on one surface thereof. The size of the coarse holes 2 varies depending on the number of the large holes, the size of the dehumidifier, etc., and is not limited to any particular one, but generally a diameter of 5 to 100 mm is suitable. Further, it is preferable to provide the coarse holes so that the area thereof is 3 to 30% of the surface of the hard case on which the coarse holes are formed. Further, the shape of the large hole 2 is not particularly limited, but any shape such as a triangle, a quadrangle, a polygon, an ellipse, etc. may be adopted in addition to the round shape shown in the figure.

Although not shown in the figure, the hard case 1 is preferably provided with an opening so that the inner bag can be replaced. As the opening / closing mechanism for the opening, a known structure is adopted without particular limitation.

Further, as the shape of the hard case, a rectangular shape is shown in FIG. 1. However, in the present invention, another shape such as an ellipse or a polygon may be used. It is possible. Further, in the dehumidifier having the shape of FIG. 1, a dehumidifier having rounded corners is also preferable for easy insertion into the gap.

Furthermore, in order to allow the hard case to be suspended by a string, a through hole may be appropriately provided near the corner of the hard case.

In the present invention, it is important that one surface of the inner bag 3 is composed of the breathable protective sheet 3-a and the other surface thereof is composed of the water impermeable sheet 3-b. That is, the hard case 1 is provided with the large holes 2, but the existence of the large holes 2 causes a problem that the unit dry bag described later is easily damaged during use. Therefore, in the present invention, in order to protect the unit dry bag, a breathable protective sheet 3-a having breathability is provided. The back surface that does not need to absorb moisture is formed of a water impermeable sheet 3-b in order to prevent moisture from entering as much as possible and to enhance the moisture absorption capacity of the surface on the side of the breathable protective sheet.

The breathable protective sheet 3-a is not particularly limited as long as it is breathable and has some resistance to external force as described above, but the moisture absorbing ability of the unit dry bag is not limited thereto. In order not to reduce the air flow rate, it is preferable to use one having a higher air permeability than the unit dry bag. Representative examples of such breathable protective sheets include non-woven fabrics, mesh sheets and perforated sheets. As the material, paper, plastics such as polypropylene, polyethylene and polyamide, and metals such as iron, copper, stainless steel and titanium are used.

As the water-impermeable sheet 3-b, a material that can substantially prevent the permeation of water and water vapor is used. A typical example is a sheet made of plastic such as polypropylene, polyethylene and polyamide.

In the present invention, the sheet does not have a strict meaning regarding the thickness, but also includes a film.

In the present invention, the inner bag 3 may be of any size so that it can be loaded into the hard case 1. However, in order to allow the unit dry bags 4 to be loaded into the hard case 1 all at once, the hard case 1 It is preferable to set the size so as to fill the inside.

The inner bag 3 is loaded with a breathable sheet facing the large hole 2 side of the hard case 1.

In the present invention, the unit dry bag 4 has a flat shape so that it can be loaded in the flat hard case, and in order to enhance the moisture absorption capacity, the breathable sheet bag is filled with a desiccant. Consists of As the breathable sheet, a sheet made of a known material that does not leak the filled desiccant and is permeable to water vapor, usually 50 μm or less, is used without particular limitation.

In particular, when a deliquescent substance is used as a desiccant described later, a desiccant having a property of being permeable to water vapor (moisture permeability) and a liquid impermeability is preferably used. Examples of the breathable sheet include a sheet obtained by stretching a thermoplastic resin containing an inorganic filler. More specifically, a thermoplastic resin such as polyolefin such as polyethylene or polypropylene, polyvinyl chloride, polyester, polyamide or the like is added with an inorganic filler in an amount of 35% by weight or more, generally 40 to 85% by weight. It is a sheet obtained by forming into a sheet and then uniaxially or biaxially stretching it at a volume stretching ratio of 50 to 500%. The inorganic filler has an average particle size of 0. Inorganic compounds such as oxides, hydroxides and salts of metals such as calcium, magnesium, aluminum and silicon having a thickness of 1 to 100 μm are used.

Further, as the breathable sheet when a deliquescent substance is used as the desiccant, a cloth having water repellency can be used in addition to the above sheets.

In the present invention, as the desiccant, known desiccants are used without particular limitation, and deliquescent substances such as calcium chloride, which have excellent moisture absorption ability, are preferably used. The above desiccant may be filled in the bag of the breathable sheet alone, but when a deliquescent substance is used, the risk of leaking of the deliquescent liquid is reduced. It is preferable to mix it with and fill the bag. Examples of the liquid-absorbent powder include crushed hollow powder such as pearlite, powder of silica, calcium silicate and the like. Further, as the gelling agent, hydroxyalkyl cellulose, polyvinyl alcohol, methyl cellulose and the like are used. The amounts of the liquid absorbing powder and the gelling agent to be used may be appropriately determined according to the deliquescent substance, but generally 0.5 to 100 parts by weight of the liquid absorbing powder to 100 parts by weight of the deliquescent substance. Parts, gelling agent 0.5 to 100 parts by weight is preferably used.

In the present invention, a plurality of unit dry bags are used by being loaded in the middle bag 3 in a state where a plurality of unit dry bags are arranged. That is, when the size of the hard case 1 is set to be almost the entire unit, the filled desiccant moves during use, resulting in unevenness. Therefore, in the present invention, as shown in FIG. 2, the size is divided into a plurality of units, and a plurality of the unit drying bags 4 are arranged and used in the middle bag 3.

The dehumidifier of the present invention is not particularly limited in other constitutions as long as it satisfies the above constitution.

The preferred embodiments of the present invention include the following embodiments.

(1) As shown in FIG. 1, a fold line 5 is provided in at least one place of the hard case 1 so that it can be folded.

According to the above aspect, when a large-area hard case is used, the storage space is not required, and it is possible to lean against a corner wall such as a push-in or a closet. It is possible to perform both moisture invasion prevention and dehumidification. In addition, the folds 5 can be formed on both sides by aligning the opposite surface of the hard case on the side where the coarse holes are present, which is suitable for inserting between futons to dehumidify. .

In the above aspect, it is preferable that the hard case is divided at the fold line 5 as a boundary, and the inner bag is loaded into each of them.

(2) As shown in FIG. 3, a transparent portion 6 is provided at the same location of the hard case and the inner bag, and an indicator showing the amount of moisture absorption is attached to the surface of the unit dry body. The main feature is generally provided on the back surface of the hard case.

(3) A mode in which a powder having another function is filled in a part of the bag of the unit dried body. Examples of the powder include antifungal agents, insect repellents, rust preventives, deodorants, fragrances and freshness-retaining agents.
