Abstract

PURPOSE:To obtain a dehumidifier attaining simultaneously the odoring, the fungi-resistant or the insect-repelling action together with the drying action by using ethylene-vinyl acetate copolymer resin impregnated with an odorant, a fungicide or an insecticide in combination with a drying agent. CONSTITUTION:An inside vessel 2 housing a drying agent 4 such as CaCl2 and providing the small holes 7 to a bottom is provided to the inside of an outside vessel 1 so that a space 8 is provided between the bottoms of both vessels and a top surface or one part of a side of the outside vessel 1 is constituted of a thin membrane 3 of a high molecular sheet which has the moisture permeability but the water nonpermeability. An ethylene-vinyl acetate copolymer resin 5 impregnated with an odorant, a fungicide or an insecticide is housed in the bottom of the outside vessel 1. Since the water content moisture-absorbed by the drying agent is stored in the bottom of the outside vessel 1 but the copolymer resin 5 is floated on the water surface, the odorant, the fungicide and the insecticide are always volatilized.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dehumidifier. More specifically, the present invention relates to a dehumidifier having fragrance, mildewproofing, or insectproofing properties.

Traditionally, simple dehumidifiers use chemical moisture absorbers such as calcium chloride, and are conveniently used for chests of drawers, food containers, closets, etc.; It may not be possible to prevent it. Therefore,
It is desirable to achieve an antifungal effect along with dehumidification. In addition to dehumidification, aromatic or insect repellent effects are also desired.

Against this background, the inventor of the present invention has conducted various studies on achieving aromatic, antifungal, or insecticidal effects as well as a drying effect, and as a result, the present inventor has developed a method of impregnating an aromatic agent, antifungal agent, or insect repellent with a desiccant agent. It has been found that this objective can be easily achieved by using the ethylene monovinyl acetate copolymer resin. The present invention is based on this knowledge.

Hereinafter, the dehumidifier according to the present invention will be explained in detail with reference to the accompanying drawings. 1 and 2 are cross-sectional perspective views of a dehumidifier showing one embodiment of the present invention. In both figures, (1) is the outer container, (2) is the inner container, (3) is a moisture permeable but impermeable thin film, (4) is a desiccant, and (5) is a fragrance, anti-mold, or insect repellent. Impregnated ethylene monovinyl acetate copolymer resin, (6)
(7) is the small hole provided at the bottom of the inner container (2), (8) is the space, (9) is the outer container (1) and the inner container (2).
) indicates the gap between That is, in the dehumidifier of the present invention, the inner container (2) is provided with an outer container (a required space 18 between the bottoms of both containers in 1j), and the inner container (2) contains a desiccant (4). to store. Although the method of providing the inner container within the outer container is not particularly limited, it is preferable that the inner container is removably fitted into the outer container. A part of the upper surface or side surface of the outer container is composed of a moisture permeable but water impermeable polymer sheet or nonwoven fabric thin film (3). These sheets or nonwoven fabrics are continuous microporous sheets or films, such as DuPont's Tyvek or Tokuyama Soda's rNFR sheet. Examples of the desiccant include calcium chloride, magnesium chloride, aluminum chloride, sodium hydroxide, urea, silica gel, and phosphorus pentoxide, with calcium chloride being particularly preferred. Thin film (3)
Moisture absorbed through the inner container drips through the small holes (forced) provided at the bottom of the inner container, and is stored in the space (8) as shown in FIG. 2 (6).

In this case, the outer container (1)
It is preferable to provide a gap (9) between the inner container (2) and the inner container (2).

The dehumidifier of the present invention uses an ethylene monovinyl acetate copolymer resin impregnated with an aromatic agent, a fungicide, or an insect repellent together with a desiccant. A fragrance is usually used as the fragrance, and the amount of this impregnated into the resin is from 20 to 100% by weight, but usually about 30% by weight is selected. In this way, this resin is most impregnated with perfume, which is unparalleled by other resins. Conventionally known fungicides and insect repellents are used, and powdered ones are usually dissolved in a solvent and impregnated. As the ethylene monovinyl acetate copolymer, vinyl acetate 10 to 5
Those containing 5% by weight are preferably used. In order to store ethylene monovinyl acetate copolymer resin impregnated with an air freshener, mold repellent or insect repellent in a container together with a desiccant agent, the two can be mixed and used, but the two can be separated separately by providing a partition. It can also be used. In particular, as shown in the attached drawing, the desiccant (4) is stored in the inner container (2) and the outer container (1
) It is preferable to store the copolymer resin (5) at the bottom of the container. In this case, the moisture absorbed by the desiccant drips from the small hole (7) of the inner container (2) and is stored (6) at the bottom of the outer container (11), so the desiccant has an extremely effective drying effect. In addition, even if water accumulates, the copolymer resin (5) will float on the water surface as shown in Figure 2, so fragrances, fungicides, or insect repellents should always be applied. It can be volatilized.
