Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the prevention of offensive odors and harmful insects inside and in the exhaust of an electric vacuum cleaner.
More specifically, the present invention provides a deodorant and insecticidal antibacterial method for an electric vacuum cleaner using a granule containing a granular substance containing a chemical consisting of a fragrance, a deodorant, an antibacterial agent and an insect repellent, the same granule and It concerns vacuum cleaners.

2. Description of the Related Art Suction-type vacuum cleaners that are widely used in homes and businesses are provided with a filter as a dust collecting member on the suction side of the main body, or a dust bag is attached to collect and separate dust. There are a reusable type and a disposable type in the dust collecting bag, and although the configurations thereof are slightly different, a cloth bag is usually used at the innermost side, and a paper bag is used at the latter. Conventionally, as dust is deposited on the dust collecting member using an electric vacuum cleaner, so-called dust odor is attached to the exhaust gas, and mites and molds propagate on the dust collecting member.

Regarding the odor when the dust bag is not used or when the cloth dust bag is used, special measures are taken because the odor is a problem only for a short time during cleaning. Not set up. For the problem of mites and molds, insects and sterilization can be performed with hot hot air, but it is impossible to carry out daily practice at home. On the other hand, in the case of a paper dust bag, a dust bag which has been subjected to insect proofing or antibacterial treatment has been proposed. However, for this purpose, since pyrethroid-based or organophosphorus-based agents are used, there is a problem that indoor air is polluted by exhaust gas containing these agents at a high concentration.

Therefore, a method has been proposed in which silica gel is carried in the dust bag or a small bag containing silica gel is inserted (Japanese Patent Laid-Open No. 3-206834). This method using silica gel is described as having an insecticidal effect on mites and a growth-suppressing effect by moisture absorption, but it has almost no effect of suppressing bacterial growth (bacteriostatic) or deodorizing effect, and is effective against dust odor. It has no effect. Further, it is troublesome to carry silica gel in the dust bag, the manufacturing cost rises, and it is expensive to insert a small bag, and silica gel is locally unevenly distributed, resulting in sufficient effect. It is not desirable because you cannot expect it.

SUMMARY OF THE INVENTION An object of the present invention is not only to easily and inexpensively remove dust odor during use of an electric vacuum cleaner, but also to diffuse an aroma into a room and to provide a dust collecting member. An object of the present invention is to provide a deodorant and antibacterial and antibacterial method capable of uniformly exerting an insect and antibacterial effect, a deodorant and insecticidal and antibacterial granule and an electric vacuum cleaner used therefor.

[0006]

Means for Solving the Problems As a result of studies to solve the above problems, the present inventor has found that a granule containing a fragrance, a deodorant, an insect repellent, an antibacterial agent, etc. in a granular substance is used. We completed a deodorant and insecticidal and antibacterial method for an electric vacuum cleaner, which is characterized in that it can be freely inserted into a dust collecting member of an electric vacuum cleaner, and a deodorant and insecticidal and antibacterial granule used for the method and an electric vacuum cleaner. In addition, in the present invention, deodorizing includes releasing an aroma and removing an offensive odor with a deodorant or the like. The details of the present invention will be described below.

In the present invention, agents such as fragrances, deodorants, insect repellents and antibacterial agents are used. As a granular substance containing these agents, a porous granular body of calcium silicate,
Examples thereof include a copolymer of ethylene and an α, β-unsaturated carboxylic acid or a derivative thereof, or an ethylene-vinyl ester copolymer (hereinafter, referred to as “specific ethylene copolymer”) powder or granules, or a mixture thereof. . As the above-mentioned specific ethylene copolymer, ethylene-ethyl acrylate copolymer, ethylene-vinyl acetate copolymer (EVA) and the like are used, but EVA is particularly preferable. Further, the specific ethylene copolymer can be used as a mixture with another polyolefin resin. Examples of other polyolefin-based resins used here include high-, medium-, and low-density ethylene homopolymers; ethylene-propylene copolymers, ethylene-butene-1 copolymers, ethylene-hexene-1 copolymers. , Ethylene-octene-1 copolymers and other ethylene-based copolymers of ethylene with other α-olefins; polypropylene and propylene-based propylene copolymers with other α-olefins Or polybutene-1, poly-4-methylpentene-1 and the like. Among these, a low density ethylene polymer is particularly preferable.

In order to incorporate the drug into the granular substance, when the drug is a liquid, it is left as it is, and when it is a solid, it is impregnated into the granular substance as a solution dissolved in a suitable solvent. When the granular substance is EVA, EVA and the solid medicine may be heated and melted and uniformly mixed, and then granulated.

The particle size of the granular material used in the present invention is important, and if it is too small, the dust bag or the like will be clogged and the suction capacity of the cleaner will be reduced. On the other hand, if the particle size is too large, it is inconvenient to handle, and since the surface area ratio of the particles becomes low, sufficient medicinal effect may not be exhibited. Considering these points, the particle size of the granular material is about 1 to 10 mm, preferably about 3 to 5 mm.

The present invention also provides an electric vacuum cleaner in which a granular substance containing a drug is charged in the intake path. The intake path here includes the inside of the intake pipe on the upstream side of the cleaner body and the cleaner dust collecting member. However, a better deodorant and bactericidal effect is obtained by charging the cleaner dust collecting member than by charging the drug-containing granular substance into the intake pipe.

Here, the method of loading the granules into the dust collecting bag and using it will be described in detail. The same can be applied when charging the other dust collecting member of the vacuum cleaner. To load the granules containing the drug in the granular material into the dust bag,
An appropriate amount of drug-containing particles is placed in the dust bag in advance. In the case of a dust bag that is repeatedly used, the drug-containing particles may be put in after the accumulated dust is removed. Of course,
Even in the case of a disposable paper bag, after the paper bag is attached, only the granules may be directly put into the dust collecting bag of the electric vacuum cleaner as it is before the cleaning, or the dust may be sucked in the same manner as in the case of sucking the dust. When the suction starts, the drug-containing particles in the dust bag randomly move in the dust bag due to the turbulent air flow in the bag, and are dispersed and uniformly attached to the inner wall of the dust bag. Even if the drug-containing particles are uneven in the initial stage of using the vacuum cleaner, the turbulent flow of air causes the particles in the surface layer of the part where the particles were thickly adhered to separate, and particles with low filtration resistance adhered. The drug particles are uniformly attached to the inner wall of the dust bag and stabilized in combination with the cross-linking action of the dust that has moved to the unfilled portion and is sucked in later.

The amount of the drug-containing particles charged varies depending on the particle size, the type of drug, the duration of the effect, the volume and aspect ratio of the dust collecting member, etc.
%, And in the range of 5 to 50 g by weight. If the amount of the drug-containing particles is too small, the desired effect will not be exhibited, and if the amount is too large, the amount of dust that can be collected will be small, which is not preferable. By charging an appropriate amount of the drug-containing particles into the dust collecting member as described above, the cleaner can be used while exerting the effect of the drug until the dust collecting member is filled with dust. Also, a plurality of types of drug-containing particles having different functions may be used in combination. At this time, different agents may be contained in different kinds of particles.

If the granules are divided into a predetermined amount in advance and hermetically packaged, and at the start of use of the electric vacuum cleaner, the package is appropriately opened and the medicine is taken out and sucked, whereby the handling becomes easy. Further, in the case of a disposable dust collecting bag, handling is further facilitated by preparing a dust collecting bag set in which a fixed amount of granules are loaded in each dust collecting bag in advance.

Examples of fragrances used in the present invention include natural fragrances, artificial fragrances, prepared fragrances and the like. As deodorant, fresh Shiraimatsu (trade name, Shiraimatsu Shinyaku)
Anico (trade name, manufactured by Minato Sangyo Co., Ltd.) and the like can be used. As the antibacterial agent, a fungicide,
A germicide or the like is used. Further, examples of insecticides against harmful insects such as mites include pyrethroid compounds.

[0015]

[Function] Since the drug is not used as it is but is contained in the granular substance by a method such as impregnation, the drug-containing particles obtained show sustained release of drug effect, and can maintain appropriate effects for a long period of time. . Since the granules are directly loaded into the dust collecting member of the vacuum cleaner and are used in a state of being dispersed on the wall surface of the dust collecting member, the granules uniformly exert their medicinal effects. Also, by selecting an appropriate particle size, clogging does not occur. To load the granules, simply vacuum with a vacuum cleaner. Therefore, the present invention can be used even in the case of a commercially available dust collecting bag. Drugs include fragrances, deodorants, insect repellents,
Antibacterial agents and the like can be used alone or in combination as appropriate. Liquid drugs can also be used.

【Example】

<Example 1> EVA pellets (trade name: Ultrasen UE633, manufactured by Tosoh Corp.) having a particle diameter of 5 mm were added to perfume-based compounded fragrances (trade name: HH-7946, Takasago International Corporation).
Granules were prepared by impregnation with 20% by weight. The dust in the dust collecting bag (1,500 ml) was removed, and the dust was attached to the vacuum cleaner to suck 5 g of the above-mentioned particulate matter. I used this vacuum cleaner for about a month, but when I used it, the fragrance was good inside the room, and I didn't feel the so-called dusty odor in the exhaust air.

<Example 2> 3 g of a calcium silicate porous granular material (trade name: Fluorite RM-30, manufactured by Tokuyama Soda Co., Ltd.) having a particle size of 3 mm was added to a deodorant solution (trade name: Biodash, Inc. ) Tokyo Biochemical Research Institute) 6g adsorbed granules 9
g was sucked into an electric vacuum cleaner equipped with a new paper bag.
This vacuum cleaner was used for about one month, but no dust odor was felt in the exhaust of the vacuum cleaner.

Example 3 9 g of granules obtained by adsorbing 6 g of commercially available cypress essential oil on 3 g of the same porous granular material as in Example 2 were sucked into an electric vacuum cleaner equipped with a new paper bag. After using this vacuum cleaner for about 3 months, the paper bag was removed and the accumulated dust was observed, but the presence of mites and mold was not confirmed.

Comparative Example 1 10 g of silica gel powder having a particle size of 0.5 mm was sucked into an electric vacuum cleaner equipped with a new paper bag. After using this vacuum cleaner for about 1 week, the dust accumulated on the paper bag was observed, but the presence of living mites was not confirmed. The dust was returned to the paper bag and the use of the vacuum cleaner was resumed, but the suction force remarkably decreased in about one week due to clogging with the silica gel powder, and the vacuum cleaner could not be used continuously. From this comparative example, it was found that the particle size of the particles is also important.

[0020]

According to the present invention, the following effects can be obtained. (1) Not only removes the exhaust odor of the vacuum cleaner, but also diffuses the fragrance indoors. (2) Suppresses the reproduction of dust mites and dust on the dust collector of the vacuum cleaner. (3) These effects are maintained until the time of removing dust from the dust collecting member or replacing the paper bag, and the initial operation is only one suction of granules, which is extremely simple. (4) Since the granules are uniformly dispersed on the wall surface of the dust collecting member of the electric vacuum cleaner, the effect of the medicine is uniformly exhibited. (5) Since the conventional dust bag can be used as it is, the cost is low.
