Description

  The present invention relates to a furniture deodorizer using ceramic particles for deodorization. More specifically, the odor component adsorbed in the fine pores of the ceramic particles that are the porous body is efficiently decomposed and deodorized by the oxidation catalyst, whereby the odor component accumulates in the fine pores of the porous body. The present invention relates to a device that prevents a decrease or saturation of the deodorizing action, has an immediate effect on the deodorizing effect, and can maintain the effect for a long period of time.

  Porous materials such as ceramics have the effect of deodorizing by physically adsorbing odor components in the fine pores on the surface, and various deodorizers utilizing this function have been proposed ( (See Patent Document 1).

JP 11-332967 A

  However, deodorization by such a method is excellent in immediate effect, but if the odor component is adsorbed and accumulated in the micropores, the adsorption action is reduced or saturated, and the deodorization effect does not last long, and the deodorizing power It is also difficult to reproduce. Moreover, even if it can be regenerated, in order to do so, for example, it takes a long time to immerse it in water for a long time to produce odor components and then to dry it sufficiently for a long time.

  In recent years, deodorization methods using an oxidation catalyst that does not have such a problem have attracted attention. According to the oxidation catalyst, the odor component is decomposed into carbon dioxide, nitrogen and the like by the oxidation reaction, and the odor component is not accumulated. However, since the oxidation catalyst is poor in the adsorption action of odor components, there is no immediate effect of the deodorizing effect.

(Purpose of the invention)
The purpose of the present invention is to efficiently deodorize the odor components adsorbed in the fine pores of the ceramic particles, which are porous bodies, by using an oxidation catalyst, thereby accumulating the odor components in the fine pores of the porous body. By providing a furniture deodorizer that uses ceramic particles for deodorization, which prevents the deterioration or saturation of the deodorizing action due to the fact that it has an immediate effect on the deodorizing effect and can maintain that effect for a long period of time. is there.

  Means taken by the present invention in order to solve the above problems are as follows.

  The present invention uses a nearly spherical deodorizing ceramic particle (1) that has a deodorizing effect on ammonia, formaldehyde, and isovaleric acid to eliminate odors that are trapped inside furniture that is normally dark. A deodorizer for furniture that smells, and is supported so that fine particles of an oxidation catalyst (11) are put in the fine pores on the surface of ceramic particles (10) having a particle size of 3 to 5 mm having many fine pores. The deodorizing ceramic particles (1) are used, and the amount of the oxidation catalyst (11) supported is 5 to 10% by weight with respect to the entire deodorizing ceramic particles (1), and the deodorizing ceramic particles (1) Is stored in a container (20) that can be ventilated between the inside and outside to form a deodorizer, and the deodorizer is housed in furniture that darkens the interior under normal conditions, and the ceramic for deodorization in the deodorizer Odor components are adsorbed in the fine pores of the grains (1), and the oxidation reaction of the oxidation catalyst (11) supported in the fine pores Decompose the care component, it is a deodorizer for furniture.

  The present invention uses a substantially spherical deodorizing ceramic particle (1) that has a deodorizing effect on ammonia, formaldehyde, and isovaleric acid, and eliminates the odor that accumulates in the interior of the cocoon that normally darkens the interior. A deodorizer for furniture that smells, and is supported so that fine particles of an oxidation catalyst (11) are put in the fine pores on the surface of ceramic particles (10) having a particle size of 3 to 5 mm having many fine pores. The deodorizing ceramic particles (1) are used, and the amount of the oxidation catalyst (11) supported is 5 to 10% by weight with respect to the entire deodorizing ceramic particles (1), and the deodorizing ceramic particles (1) Is stored in a container (20) that can be ventilated between the inside and outside to form a deodorizer, and the deodorizer is attached to the inside of the curtain (30) of the bowl (3) to remove the deodorizer inside the deodorizer. Odor components are adsorbed in the fine pores of the ceramic particles (1) for use in the interior of the soot by the oxidation reaction of the oxidation catalyst (11) supported in the fine pores. The molar odor to deodorant, a deodorizer for furniture.

  The deodorizer for furniture according to the present invention, the ceramic particles for deodorization (1), a container for stirring, a large number of ceramic particles (10), colloidal oxidation catalyst (11) and oxidation catalyst (11) Alcohol, which is a dispersion medium, is placed so that the fine particles can be easily dispersed. The fine particles of the oxidation catalyst (11) dispersed in the alcohol are attached to be almost even, and the fine particles of the oxidation catalyst (11) enter into the fine pores that are innumerable on the surface of the ceramic particles (10). The alcohol adhering to or penetrating the surface of each ceramic particle (10) is volatilized to adhere or fix the fine particles of the oxidation catalyst (11) to the ceramic particles (10). Deodorant ceramic grains (1) to 5-10% by weight of the whole More preferably.

(Work)
The effect | action of the ceramic grain for deodorizing which concerns on this invention, and the furniture deodorizer using the same is demonstrated.
In addition, here, each constituent element used in the description is assigned in correspondence with the reference numeral given to each part in the embodiment described later, and this reference numeral is added to each claim of the utility model registration claim. As in the case of the reference numerals described, it is only for facilitating the understanding of the description, and the meaning of each component is not limited to the above-described parts.

The deodorant ceramic particle (1) according to the present invention is a fine particle of the oxidation catalyst (11) contained in the fine pores, the odor component adsorbed in a number of fine pores of the porous ceramic particles (10) Can be decomposed and deodorized by oxidation reaction. Odor components are decomposed into carbon dioxide, nitrogen, and the like by the oxidation reaction, and therefore do not accumulate in the adsorbed micropores.
As a result, it is possible to prevent the deodorizing effect from being reduced or saturated due to the accumulation of odorous components in the micropores of the porous body, so that the deodorizing effect is immediately effective in combination with the adsorption action by the micropores. Can be maintained for a long time (in theory, semi-permanently).

Further, since the deodorizing ceramic particles (1) are granular, for example, if the deodorizing material is composed of a large number of particles, the particles are formed in a smaller diameter (for example, 3 to 5 mm), thereby forming a sheet The surface area per unit weight (including the surface area in the micropores) can be increased more easily than the conventional ones. If the particle size of the ceramic particles (10) is less than 3 mm, the manufacturing cost will increase and the product price will be affected. If the particle size of the ceramic particles (10) exceeds 5 mm, the surface area will be increased. There is a tendency to be disadvantageous.
Thus, by increasing the surface area as the deodorizing material, the contact area with the air containing the odor component also increases, and more effective deodorization can be performed.

The ceramic particles (10) used in the deodorant ceramic particles (1) according to the present invention are more preferably water-absorbing (liquid-absorbing) or moisture-absorbing having a water absorption rate of 40 to 70% by weight. .
As described above, the ceramic particles (10) themselves have good water absorption or hygroscopicity, so that the fine particles of the oxidation catalyst (11) are immersed in a liquid (such as a colloid liquid) containing the fine particles, and the liquid is applied. Or the operation | work supported by spraying can be performed efficiently. That is, at the time of production, the liquid containing the fine particles is quickly and quantitatively contained in the ceramic particles (10), so that the fine particles of the oxidation catalyst (11) entering the fine pores are also increased.

More preferably, the deodorizing ceramic particles (1) according to the present invention have a loading amount of 5 to 10% by weight of the oxidation catalyst (11) with respect to the entire deodorizing ceramic particles (1).
The deodorizing effect and convenience of use of the deodorizing ceramic particles (1) by setting the amount of the oxidation catalyst (11) supported on the entire deodorizing ceramic particles (1) to 5 to 10% by weight ( Usability) is a good balance for both.

That is, when the supported amount of the oxidation catalyst (11) is less than 5% by weight, the fine particles of the atomy ball (11) adhering to the surface of the ceramic particles (10) or entering the micropores on the surface are quantitatively reduced. Therefore, there is a tendency that the deodorizing power required as a product cannot be sufficiently exhibited.
When the amount of the oxidation catalyst (11) supported exceeds 10% by weight, the amount of fine particles of the oxidation catalyst (11) adhering to the surface of the ceramic particles (10) or entering the micropores on the surface increases in quantity.

As a result, if the pores of the fine pores are blocked by the fine particles of the oxidation catalyst (11), the action of once adsorbing the odor component by the fine pores is lost, and there is a tendency that the immediate effect is lost and the deodorizing power cannot be sufficiently exhibited. is there. Further, in this case, the oxidation particles (11) supported on the ceramic particles (10) are too many, and the deodorizing ceramic particles (1) come into contact with each other, so that the particles are peeled off and the surroundings are stained. There is also a tendency to end up.
By making the loading amount of the oxidation catalyst (11) with respect to the deodorant ceramic particles (1) as a whole 5 to 10% by weight, the above-mentioned problems can be suppressed, and the deodorizing effect and use of the catalyst can be suppressed. It will be a good balance of convenience.

  Examples of odors that can be deodorized by the oxidation reaction of the oxidation catalyst (11) include general malodors such as ammonia and hydrogen sulfide, body odors such as nonenal (aging odor) and isovaleric acid, and odors from building materials such as formaldehyde. However, the oxidation catalyst has a good deodorizing effect on other odor components.

  Further, the deodorizing ceramic particles (1) according to each of the above claims are contained in a container (20) so that the deodorizing ceramic particles (1) do not leak to the outside, and the container (20) The air permeable between the interior and the exterior, and the member (23a) that closes the housing portion after housing the deodorizing ceramic particles (1) is configured so that it cannot be removed after installation. The odor device (2), for example, can be stored in various furniture such as bags, bags, cupboards, clogs (shoe boxes), etc. to eliminate the odors that have accumulated inside these furniture. It becomes possible to use comfortably.

  Furthermore, since the member (23a) that closes the housing portion cannot be removed once it has been attached, it can be easily removed even if the deodorizer (2) is removed or shocked. In addition, the contained deodorizing ceramic particles do not jump out of the container and are not scattered.

(A) The deodorizing ceramic particle according to the present invention decomposes the odor component adsorbed in a large number of fine pores of the ceramic particles, which are porous bodies, by an oxidation reaction by the fine particles of the oxidation catalyst contained in the fine pores. Can be deodorized. Odor components are decomposed into carbon dioxide, nitrogen, and the like by the oxidation reaction, and therefore do not accumulate in the adsorbed micropores. As a result, it is possible to prevent the deodorizing effect from being reduced or saturated due to the accumulation of odorous components in the micropores of the porous body, so that the deodorizing effect is immediately effective in combination with the adsorption action by the micropores. Can be maintained for a long time.
In addition, since the deodorizing ceramic particles are granular, if the deodorizing material is composed of a large number of particles, by forming the particles to have a smaller diameter, for example, the same weight or It is easy to increase the surface area per same size. Thus, by increasing the surface area as the deodorizing material, the contact area with the air containing the odor component also increases, and more effective deodorization can be performed.

(B) When the ceramic particles have a water absorption or hygroscopicity of 40 to 70% by weight, the ceramic particles themselves have a good water absorption or hygroscopic property. It is possible to efficiently perform the work of carrying by immersion in a liquid containing fine particles, application or spraying of the liquid. That is, at the time of production, the ceramic particles are rapidly and quantitatively contained in the liquid containing the fine particles, so that more oxidation catalyst fine particles enter the micropores, so that the deodorizing effect becomes higher. .

(C) The amount of the oxidation catalyst supported on the entire deodorant ceramic particles is 5 to 10% by weight, which is excellent in that both the deodorizing effect and the convenience of use of the deodorant ceramic particles are compatible. It becomes a balance and the functionality as a product becomes high.

(D) The furniture deodorizer according to the present invention can be used by, for example, storing it in various furniture such as bags, baskets, cupboards, clogs, etc. It smells and can be used comfortably. In addition, since the member that closes the housing part cannot be removed once it has been attached, it will not come off easily even if the deodorizer is removed or a shock is applied. Ceramic grains do not jump out of the container and clutter. Also, it can be prevented from being messed up by mischief of children.

  The present invention will be described in detail based on the embodiments shown in the drawings.

FIG. 1 is a cross-sectional explanatory view of a deodorizing ceramic grain according to the present invention,
2A and 2B are explanatory views of the surface of the deodorant ceramic particles, wherein FIG. 2A is an enlarged explanatory view before the atomy ball is supported, and FIG.

  The ceramic particles 1 for deodorization are substantially spherical and are made to have a diameter of about 4 mm. The deodorizing ceramic particles 1 have ceramic particles 10 that are granulated by firing a mixture of zeolite and clay in a required ratio and mixing them. The ceramic grain 10 is a porous body having fine pores (or fine gaps) continuous on the surface and having a water absorption rate of 50% by weight. The raw material for the ceramic particles 10 is not limited to zeolite and clay as described above, and other raw materials can be used as long as they become porous ceramics by firing.

On the surface of the ceramic particle 10, fine particles of an atomy ball 11 as an oxidation catalyst are supported. ATOMY BALL (trade name: Catalytic Chemical Co., Ltd.) is a silver-based colloidal inorganic agent (water dispersion type) having antibacterial function, bactericidal function, deodorizing function and the like.
The amount of the fine particles supported is about 10% by weight with respect to the entire ceramic particle 1 for deodorization. The fine particles (colloid particles) of the atomy ball 11 enter innumerable fine holes (reference numerals omitted) on the surface of the ceramic particles 10 (see FIG. 2). Thereby, the odor component (odor substance) adsorbed by the micropores can be efficiently decomposed and deodorized by the fine particles of the atomy ball 11 present in the vicinity thereof.

Here, an example of the manufacturing method of the ceramic particle 1 for deodorizing is demonstrated.
(1) A total of 100 g of ceramic particles 10 and 12 g of atomy balls 11 (colloidal shape) are placed in a container for stirring, and 50 ml ( Alcohol, which is a dispersion medium of which amount can be adjusted as appropriate, was added. In addition, as a dispersion medium, other things, such as water other than alcohol, can also be used.

(2) The ceramic particles 10, atomy balls 11 and alcohol placed in a container (not shown) are agitated as a whole, so that the fine particles of the atomy balls 11 dispersed in alcohol on the surface of each ceramic particle 10 are made substantially uniform. Adhered to. The ceramic particles 10 had a water absorption rate of 50% by weight, and the water absorption rate was high. Therefore, the alcohol in which the fine particles of the atomy balls 11 were dispersed was quickly absorbed by the ceramic particles 10. As a result, the fine particles of the atomy ball 11 entered the fine holes existing innumerably on the surface of the ceramic particle 10.

(3) When the alcohol adhering to or penetrating the surface of each ceramic particle 10 was volatilized, the fine particles of the atomy ball 11 adhered or fixed to the ceramic particle 10. As a result, the deodorizing ceramic particles 1 in which the amount of fine particles carried by the atomy balls 11 was about 10% by weight with respect to the entire deodorizing ceramic particles 1 were obtained. The alcohol may be volatilized naturally, but various known drying means such as sending warm air or hot air can be used.

(Work)
The effect | action of the ceramic particle 1 for deodorizing which concerns on this Embodiment is demonstrated.
The deodorizing ceramic particles 1 can deodorize the odor components adsorbed in the numerous fine pores of the ceramic particles 10 by decomposing them by oxidation reaction with the fine particles of the atomy balls 11 contained in the fine pores. The odor component is decomposed into carbon dioxide, nitrogen and the like by the oxidation reaction and is not accumulated in the adsorbed micropores, so that the deodorizing action can be prevented from being lowered or saturated. As described above, the deodorizing ceramic particles 1 have an immediate effect on the deodorizing effect in combination with the adsorption action by the fine pores, and the effect can be maintained for a long time.

  Moreover, since the deodorizing ceramic particles 1 are particles having a particle size of about 4 mm, the surface area per unit weight (including the surface area in the micropores) is the same as that of, for example, a sheet. Easy to enlarge. Thus, by increasing the surface area as the deodorizing material, the contact area with the air containing the odor component also increases, and more effective deodorization can be performed.

  Since the ceramic particles 10 used for the deodorizing ceramic particles 1 have a water absorption (liquid absorption) with a water absorption rate of 50% by weight, a liquid containing fine particles of the atomy balls 11 is produced in the ceramic particles 10 during production. It is quickly and quantitatively included. Thereby, the fine particles of the atomy ball 11 which enter into the fine holes are increased, and a better deodorizing ability can be exhibited.

  The deodorizing ceramic particle 1 has a loading amount of about 10% by weight with respect to the entire deodorizing ceramic particle 1 of the atomy ball 11, so that the deodorizing ceramic particle 1 can exhibit a good deodorizing ability as described above and is supported. Since the amount is not excessive, the fine particles of the atomy ball 11 are not peeled off by rubbing between the deodorizing ceramic particles 1, and the surroundings are not contaminated. This provides a good balance of both convenience of use.

  An experiment was conducted to confirm the deodorizing effect of the ceramic particles 1 for deodorizing according to the present embodiment. The experiment was performed as follows.

(experimental method)
40 g of deodorant ceramic particles according to the present embodiment were placed in a 5 L Tedlar bag with an internal volume, and 3 L of experimental gas was injected as an odor component. Three types of experimental gases were used: ammonia, formaldehyde, and isovaleric acid. Then, after 0 minute (at the start of the experiment), 5 minutes, 2 hours, and 24 hours after each experimental gas in this state, the experimental gas concentration in the Tedlar bag is measured to determine the deodorizing ability for each experimental gas. It was. In addition, a blank experiment (unused deodorant ceramic particles) was performed under the same conditions as a comparison object.
The concentration of the experimental gas was measured in a room environment at a temperature of 20 ° C. using a detector tube method. The experimental results are shown in Table 1.

As shown in Table 1, when deodorizing ceramic particles 1 were used as deodorizing materials in deodorizing experiments of ammonia, formaldehyde, and isovaleric acid experimental gases, the deodorizing effect was obvious compared to the blank experiment. Was recognized.
That is, in any of the experimental gases, the odor was almost deodorized after 2 hours from the start of the experiment, and further deodorized to a very low level after 24 hours. In particular, in the deodorization experiment of ammonia, the deodorization is immediately performed from 40.0 (ppm) at the start of the experiment to 20.0 (ppm), which is a half after 5 minutes. It was.

FIG. 4 is a perspective explanatory view of a state in which the furniture deodorizer is attached to the bag.

  The furniture deodorizer 2 includes a synthetic resin hollow container 20 whose outer shape is a rectangular parallelepiped shape, and a required amount (for example, 40 g) of the deodorizing ceramic particles 1 is accommodated therein. One component plate 21 on the long side and the narrow side of the hollow container 20 is provided with a double-sided tape 22 to be attached to the inside of the curtain plate 30 of the tower 3. The double-sided tape 22 used had a heat-resistant temperature of 120 ° C. Although the double-sided tape 22 is used in the present embodiment, the present invention is not limited to this, and various known attachment means such as a hook-and-loop fastener can be employed.

  Of the hollow container 20, each component plate 23 excluding the component plate 21 is provided with a large number of vent holes 24 that can vent between the inside and the outside of the hollow container 20 on almost the entire surface. The diameter of each vent hole 24 is set to 3 mm so that the deodorizing ceramic particles 1 having a particle diameter of 4 mm do not pass through and leak to the outside. In addition, among the constituent plates 23, the constituent plate 23a on the short side and the narrow side is attached after the deodorant ceramic particles 1 are accommodated and cannot be removed after attachment (about the attachment structure). Is omitted because it employs known means).

  The size of the hollow container 20 is, in the present embodiment, the long side length (lateral length in FIG. 3) 178 mm, the short side length (vertical length in FIG. 3) 35 mm, The thickness is set to 17 mm. In addition, since the yagura which is the object to be attached in this embodiment has a length (250 to 300 mm) and a vertical width (40 to 50 mm) in the frame of the curtain and the brace, The size of the hollow container 20 is set so as to be accommodated therein, but is not limited to the above. Moreover, you may employ | adopt the thing of another shape and size as what is attached to other furniture, such as a clog box.

If the furniture deodorizer 2 according to the present embodiment is attached to the tower 3 as shown in FIG. 4, the odor accumulated inside the tower 3 can be removed and used comfortably.
It should be noted that there is almost no ultraviolet rays inside the tower 3 even in a dark state when not in use and when an infrared heater is lit when in use. However, the deodorizing ceramic particles 1 of the furniture deodorizer 2 carry an oxidation catalyst and react if there is oxygen, so deodorization is possible even under the above conditions unlike photocatalysts. It is. The same applies to furniture that normally becomes dark inside.

  Furthermore, as described above, the component plate 23a constituting the hollow container 20 cannot be removed once it has been attached, so it can be easily removed even if the deodorizer is removed or shocked.
