Description

  The present invention relates to a dust adsorbing piece for cleaning, a vacuum cleaner using the same, a dust filter, and an allergen recovery cleaning method.

  In the cleaning using a scissors or a vacuum cleaner, there is a problem that fine dust and dirt are scattered without being collected by exhaust air or the like. As means for solving such a problem, Japanese Patent Laid-Open No. 2005-110964 (Patent Document 1) introduces and mixes a fluid semi-fixed slime substance into dust stored in a dust collection chamber of a vacuum cleaner. It is described that dust containing mites and the like is taken into the slime-like substance and discarded together with the slime-like substance. Japanese Patent Laid-Open No. 63-23631 (Patent Document 2) discloses dust that has been sucked from the air intake in order to prevent fine dust from passing through the mesh of the dust collecting bag and re-scattering during cleaning. It describes that it is collected by spraying water collected in the dust collection chamber.

In addition, dust includes fine mites and their carcasses, and mite allergy is known to be involved in atopic dermatitis, bronchial asthma, and the like (see Non-Patent Document 1). That is, there has been a demand for more reliably removing and collecting fine dust containing mite allergens and the like during cleaning. As a general countermeasure against mite allergies, there is a method of inactivating allergens in a vacuum cleaner. Japanese Patent Application Laid-Open No. 10-75924 (Patent Document 3) discloses a method for detecting mite adsorbed and retained on the surface or inside of a cleaning tool. A cleaning tool that has been treated with an adsorbent to suppress growth is described. The applicant has already disclosed a surfactant that inactivates allergens derived from mite feces and / or mite carcasses (Patent Document 4).

  In the vacuum cleaner of Patent Document 1, the slime-like substance is swirled in the dust collection chamber and only dust is adsorbed and collected on the surface of the slime-like substance, so that dust penetrates into the slime-like substance. However, there is a problem that the amount of collected dust is small only by surface adsorption. Further, the slime-like substance adheres to the wall surface in the dust collection chamber, and the amount of the gradually turning slime-like substance is reduced, so that the collection effect is lowered and it is difficult to use for a long time. In addition, as described above, Patent Document 2 describes that suction air is blown against water stored in a dust collection chamber to collect dust in the air. However, when the air flow collides with the water surface, the water droplets are scattered in the cleaner, and the interior of the cleaner is exposed to the water droplets. Therefore, there is a problem that the manufacturing cost is increased due to the necessity of the waterproof structure.

  Patent Document 3 describes performing an adsorbent treatment on a cleaning tool. However, the amount of dust adsorbed depends on the size and surface structure when adsorbed on the surface of the cleaning tool or the inner surface of the dust bag, but the material and size depend on the place of use and the required strength. It is selected according to. Therefore, even if the adsorbent treatment is performed, the amount of dust adsorbed on the conventional cleaning tool has reached its limit.

  Further, when the adsorbent treatment is performed on the cleaning tool itself, dust and dirt are often unevenly attached during cleaning, and the dust is detached and scattered from a location where a large amount of dust is locally attached. In the case of vacuum cleaner dust bags and filters, dust was exhausted to the outside. Accordingly, allergens contained in mite carcasses and feces contained in the dust are also detached, which may act on humans as allergens.

And is highly safe for the human body.

  According to the second aspect of the present invention, since at least the surface of the small piece is formed from a three-dimensional adsorption structure that increases the surface area thereof, the amount of the dust adsorbent carried increases and the dust adsorption area increases. By increasing, the amount of collected dust can be remarkably improved. The adsorbing structure can use small pieces of various shapes as long as the durability is maintained so as not to be detached from the dust adsorbing pieces, and if a suitable material is selected, the surface area is larger. It is possible to provide a dust suction piece having an increased dust suction surface.

  According to the third aspect of the present invention, since the shape of the small piece is granular, spherical, linear, string-like, sheet-like or polyhedral, depending on the place to be cleaned and the cleaning tool, A shape suitable for the material can be selected. Therefore, the dust adsorbing piece according to the present invention can be manufactured relatively easily only by processing the material selected from the use conditions into an appropriate size according to the shape and characteristics of the commercially available material. For example, when a fiber material is used as the raw material of the small piece, the dust adsorbing piece according to the present invention can be easily manufactured by using a string-like or linear small piece using an existing material or apparatus.

  According to the fourth aspect of the present invention, since the small pieces are formed by agglomerating or bonding materials, the surface area is relatively large, and the amount of the dust adsorbent supported is increased. A dust adsorbing piece with high efficiency can be provided. In addition, since the material is an irregular structure formed by agglomerating or bonding the materials, a dust adsorbing piece having a relatively large surface area and an increased amount of dust can be easily manufactured.

  According to the fifth aspect of the present invention, since the small pieces are formed by arranging linear or string-like materials radially from the center of the small pieces, they have a relatively large surface area and are nearly spherically symmetric.

If批表area 0.05 m 2 / ^g less, it is difficult to adsorb very fine dust, the specific surface area utilizes 3000 m 2 / ^g or more fibrous material increases the manufacturing cost of the piece . For example, when using non-woven activated carbon, a long activation time is required at a high temperature in order for the specific surface area to exceed 3000 m ² / g. Therefore, by using a fiber material whose specific surface area is set in a range of 0.05 to 3000 m ² / g, it is possible to provide a dust adsorbing piece that has a large amount of dust collection and can be manufactured at a relatively low cost. it can.

Can be set to any value. That is, when the supported amount% is smaller than 0.5, it becomes difficult to adsorb dust, and when it exceeds 40% by mass, the mass of the dust adsorbing piece becomes too large or excessive adsorbent is deposited on the small piece. The dust adhering pieces may adhere to the accommodation location or the object to be cleaned. Furthermore, if the carrying amount is 40% by mass or less, by setting the mass of the dust adsorbing piece to a predetermined value, even when stirring in a cleaner, the air can be suspended and disturbed.

At this time, dust contained in the suction air is separated. During the separation, the dust adsorbing piece 1 is suspended and disturbed by the air flow. By this agitation, the adsorption of the dust adsorbing pieces 1 becomes active, and the sucked fine dust can be collected. Further, when an anti-allergenic surfactant is added to the dust adsorbent, the allergen contained in the sucked dust can be recovered by collecting fine dust and adsorbing to the dust adsorbing piece 1. A small piece size of the dust adsorbing piece is about 3 cm square, but a size smaller than about 3 cm square can be used as long as this size is at least a size not sucked from the exhaust port 16 (diameter: about 5 mm).
In addition, if the dust filter provided in the exhaust port of the vacuum cleaner main body 4 is formed by accumulating a plurality of dust adsorbing pieces 1, a filter that reliably adsorbs allergens and allergen-containing materials to the small pieces together with fine dust. An effect can be obtained.

  FIG. 4 is a schematic configuration diagram showing another embodiment of the dust adsorbing piece according to the present invention. The dust adsorbing piece 31 in the figure has a multilayer structure, and each member is formed of a nonwoven fabric. An intermediate portion 36 is bonded in a wave shape on the lowermost surface portion 34, and an upper surface portion 38 is further bonded thereon to form one layer. The intermediate portion 36 formed in a wave shape can effectively use the surface of the nonwoven fabric material of the dust adsorbing piece 31 and is given elasticity. Further, the lower surface portion 33 and the intermediate portion 35 are bonded to form the next layer, and the uppermost surface portion 32 is laminated. By using such a three-dimensional structure as a dust adsorbing piece, the surface area to which dust is attached can be significantly improved.

Table 1 below shows evaluations of Examples 1 and 2 and Comparative Examples 1 to 3 using spherical cotton as a material for the dust adsorbing piece according to the present invention. In the following evaluation, a plurality of dust adsorbing pieces shown in Examples and Comparative Examples are put in the same weight in a dust cup of a cyclone type vacuum cleaner, and JIS test dust (cotton powder) scattered on the floor is sucked into the dust. The “adhesion degree (attachment of cotton)” to the dust adsorbing pieces in the cup is compared. Here, both a stand type and a canister type are used for the cyclone type vacuum cleaner.
Furthermore, together with the above-mentioned degree of adhesion (adhesion of cotton), “no dirty cup” and “no filter dirt” are also evaluated. In all the evaluations, “very good” is indicated by “◎”, “good” is indicated by “◯”, “somewhat inferior but available” is indicated by “△”, and “bad” is indicated by “x”. In Examples 1 and 2, 5 wt% and 10 wt% of the oil agent are carried as the dust adsorbent, respectively, compared with Comparative Examples 1 and 2 using water as the adsorbent and the case where no adsorbent is carried. It turns out that there is no cup dirt. By using the oil agent, fine dust is adsorbed and the contamination of the filter is reduced. This is because, in the case of an oil agent, the cotton powder that has not been adsorbed is prevented from adsorbing and scattering from each other, and clogging of the filter is prevented.
However, even when the oil agent was supported on the spherical cotton, no difference was observed with respect to the adhesion of the cotton powder to the case where water was used as the adsorbent to such an extent that it could be clearly discerned by visual recognition.

FIG. 5 is a schematic configuration diagram showing a spherical dust adsorbing piece 41 formed using an acrylic fiber according to the present invention. The dust adsorbing piece 41 is formed so that a string-like member 42 made of acrylic fiber is bundled at a central portion by a bundling member 43 and the string-like member 42 projects radially. Table 2 below shows test results of evaluation using the dust adsorption piece 41 of FIG. 5 by the same method as in Table 1.
As shown in Table 2, compared with the cotton in Table 1, when an oil agent is used as the dust adsorbent, very good results are obtained in all evaluations. Moreover, compared with the case where water is used as the adsorbent, the absence of cup contamination is improved.

  Table 3 shows evaluation of dust adsorbing pieces made of non-woven fabric (including non-woven activated carbon) or pile in the same manner as in Tables 1 and 2. Moreover, in FIG. 6, the state of the dust adhering to the dust adsorption change which consists of a mop pile which concerns on this invention is shown. As shown in Table 3, the nonwoven fabrics (Examples 5 and 6) and the piles (Examples 7 and 8) carrying the dust adsorbent gave good or very good results in all evaluations. Furthermore, in detail, the non-woven fabric of Example 6 (large) has improved filter stain resistance compared to the 1 / 8-size non-woven fabric (small) shown in Example 5. Here, the nonwoven fabric (large) of Example 6 has a maximum length of about 20 mm. That is, when the size is larger than the predetermined size, the function of the dust adsorbing piece is exhibited.

  Table 4 shows the evaluation of the stirring state in the vacuum cleaner using a plurality of spherical dust adsorbing pieces made of acrylic fibers shown in FIG. If the stirring state of the dust adsorbing pieces is evenly stirred without sticking to each other, “very good” means “◎”, “good” means “good”, and “somewhat inferior is available” In “Δ”, “bad” is indicated by “x”. As shown in Table 4, a suitable stirring state is realized when the mass of the spherical dust adsorbing piece is 0.01 g to 10 g and the maximum length is 1 mm to 50 mm, and dust can be adsorbed more reliably. .

  The present invention is not limited to the above-described embodiments, examples and modifications, and includes various modifications and design changes within the technical scope without departing from the technical idea of the present invention. It goes without saying that there is. For example, in the cyclone type vacuum cleaner, the suction unit 3 is attached to the connection pipe 10, but the present invention can also be applied to a vacuum cleaner in which the suction unit 3 is provided on the electric vacuum cleaner body 4 side.

  Dust that can be used in an existing vacuum cleaner without attracting and collecting fine dust, including allergens, more reliably by using the dust adsorbing piece according to the present invention, so that fine dust does not diffuse again. An adsorption piece, an electric vacuum cleaner using the same, a dust filter, and a cleaning method are provided. Moreover, the vacuum cleaner provided with the antiallergen countermeasure function is realizable. By using this dust-adsorbing piece for cleaning, allergen activity of allergens that have plagued people for many years, such as allergic diseases such as atopic dermatitis, asthma, fever, eczema, urticaria, etc., is effective. Can be reduced.
