Description

TECHNICAL FIELD The present invention relates to a deodorizing filter laminate that adsorbs malodorous components and deodorizes.

Conventionally, charcoal (particularly activated charcoal) is known to have a high deodorizing effect. Charcoal is a porous material with many pores, and its surface area is said to be 200m ² to 400m ² per gram. As a result, charcoal adsorbs odorous substances by strong intermolecular force, and exhibits a deodorizing effect. For this reason, various deodorizing devices using the deodorizing effect of charcoal have been proposed, as shown in Patent Document 1 and Patent Document 2.

For example, Patent Document 1 discloses a deodorizing device technique in which a filter mainly composed of activated carbon and copper ions and a filter mainly composed of a metal catalyst and an adsorbent are arranged in series. Further, Patent Document 2 discloses a technique of a deodorizing device provided with two or more deodorizing filters containing a deodorizing material. According to these technologies, it is said that odorous substances can be quickly removed and a comfortable environment can be created.

However, the aforementioned technology is a technology that enhances the deodorizing effect by combining a filter using charcoal and a filter using something other than charcoal. Not considered.

The present invention has been made in view of such conventional circumstances. One of the objects of the present invention is to provide a deodorizing filter laminate with high deodorizing performance.

Means for solving the problem and effects of the invention

A deodorizing filter laminate according to a first aspect of the present invention is interposed between a filter part having a deodorizing member made of granular charcoal or granular activated carbon and a plurality of the laminated filter parts, and a spacer portion providing a gap between the portions, wherein the filter portion is composed of a first honeycomb structure formed by connecting a plurality of hollow columnar bodies so that the side portions are in contact with each other, and a material having air permeability, It can have a first package enclosing the deodorizing member and the first honeycomb structure such that the deodorizing member is arranged inside the hollow columnar body of the first honeycomb structure. According to the above configuration, since the gap is provided between the filter portions, the amount of air passing through the filter portions increases, and the deodorizing effect can be enhanced.

Moreover, the deodorizing filter laminate according to the second aspect of the present invention can have a second honeycomb structure in which the spacer portion connects a plurality of hollow columns so that the side portions are in contact with each other. According to the above configuration, it is possible to provide a gap between the filter portions using the honeycomb structure. Also, the same honeycomb structure can be used for the first honeycomb structure and the second honeycomb structure.

(Deodorizing filter laminate 1)

A deodorizing filter laminate 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG.

As shown in FIG. 1, the deodorizing filter laminate 1 has three filter portions 11 and two second honeycomb structures 12 (corresponding to an example of a "spacer portion" and a "second honeycomb structure" in the claims). ) and one second package 13, which is used in combination with the housing 2 and the fan 3 to form a deodorizing device as shown in FIGS. Each member is described below.
(Filter section 11)

The filter part 11 is a member composed of a deodorizing member 11a, a first honeycomb structure 11b, and a first package 11c, as shown in FIG.
<Deodorizing member 11a>

The deodorizing member 11a is granular charcoal (preferably activated charcoal) as shown in FIG. Charcoal is a porous material with many pores and is characterized by a large surface area. The deodorizing member 11a according to the present invention further increases the surface area by granulating such charcoal. As a result, the deodorizing member 11a can adsorb odorous substances by strong intermolecular force, and can effectively deodorize.

The deodorizing member 11a is not limited to the above embodiment, and may be a mixture of materials having a deodorizing effect other than charcoal. The particle size of the charcoal is not particularly limited, but smaller ones are preferable because the overall surface area is larger, the deodorizing effect is enhanced, and the air permeability of the filter section 11 is enhanced (pressure loss is reduced). Furthermore, the amount of the deodorizing member 11a used in the filter portion 11 is not particularly limited. If the amount of the deodorizing member 11a is increased, the period during which the deodorizing effect of the filter portion 11 lasts becomes longer, and if the amount of the deodorizing member 11a is reduced, the air permeability of the filter portion 11 increases.
<First honeycomb structure 11b>

As shown in FIG. 4, the first honeycomb structure 11b is formed by connecting a plurality of hollow cylindrical bodies so that their side surfaces are in contact with each other to form a honeycomb (here, "honeycomb" means "regular hexagonal columns arranged without gaps"). It is not limited to the narrow meaning of "", but the broad meaning of "not limited to regular hexagonal prisms but solid figures arranged without gaps".) It is a substantially rectangular member that forms a structure. Inside the hollow columnar body of the first honeycomb structure 11b, the deodorizing member 11a is enclosed in the first package 11c in a state of being arranged so as to form a gap. At this time, it is preferable that the amount of the deodorizing member 11a disposed inside each hollow columnar body is substantially uniform so that the air permeability in the one filter portion 11 is not biased.

In addition, the first honeycomb structure 11b is not limited to the above aspect. For example, a honeycomb structure may be formed by connecting hollow triangular prisms so that their side surfaces are in contact with each other, or hollow hexagonal prisms may be connected so that their side surfaces are in contact with each other to form a honeycomb structure. Also, the outer shape is not limited to a substantially rectangular shape.
<First package 11c>

The first packaging body 11c is made of mesh fabric, and as shown in FIG. 4, is a member that encloses the first honeycomb structure 11b and the deodorizing member 11a so as to follow the substantially rectangular shape of the first honeycomb structure 11b. is. As a result, the positional relationship between the first honeycomb structure 11b and the deodorizing member 11a (the deodorizing member 11a is placed inside the hollow columnar body of the first honeycomb structure 11b, and the gap between the first package 11c and the air permeability is maintained) can be maintained). That is, it is possible to prevent the deodorizing member 11a arranged inside one hollow columnar body from moving to the inside of another hollow columnar body, and the amount of the deodorizing member 11a arranged inside each hollow columnar body being extremely unbalanced. .
(Second honeycomb structure 12)

The second honeycomb structure 12 is a member arranged between the three filter portions 11 as shown in FIG. 1, and is the same member as the first honeycomb structure 11b. By arranging the second honeycomb structure 12 between the filter portions 11 , a gap can be provided between the filter portions 11 . The present inventor has confirmed by experiments that the wind speed of the air passing through the deodorizing filter layered body 1 increases by providing a gap between the filter portions 11 (details will be described later). That is, since the amount of air passing through the filter section 11 per unit time increases, the deodorizing effect is enhanced.

In addition, the second honeycomb structure 12 is not limited to the above-described mode as long as it can provide a gap between the filter portions 11 . However, from the viewpoint of productivity improvement, since it is not necessary to manufacture different members for the first honeycomb structure 11b and the second honeycomb structure 12, it is better to use the same member as the first honeycomb structure 11b. preferable.
(Second package 13)

As shown in FIG. 1, the second package 13 is a substantially rectangular box made of paper, and has circular holes on the plane and the bottom for allowing air to pass through. The second package 13 can enclose the three filter parts 11 and the two second honeycomb structures 12 in an alternately laminated state. That is, the second package 13 can bundle a plurality of filter portions 11 into one member (deodorizing filter laminate 1) in a state in which gaps are provided between the filter portions 11 to enhance the deodorizing effect. That is, attaching the deodorizing filter laminate 1 to the housing 2 is preferable because it means that a plurality of filter portions 11 are attached to the housing 2, and the need to adjust the gaps between the filter portions 11 is eliminated. Moreover, the plurality of filter units 11 can be removed from the housing 2 by removing the deodorizing filter laminate 1 .

The second package 13 is not limited to the above-described mode, and the size and shape of the second package 13 itself and the size and shape of the hole may be changed as appropriate. Moreover, the numbers of the filter part 11 and the second honeycomb structure 12 to be included are not limited to those described above. Moreover, the second package 13 does not necessarily have to be provided.
(Case 2)

As shown in FIGS. 2 and 3, the housing 2 includes a housing main body 21 which is a cylindrical member having a substantially rectangular cross section, and a deodorizing filter laminate 1 and a fan 3 mounted inside the housing main body 21. It is composed of mounting portions 22 and 23 for the air intake and has an air intake port 24 and an air exhaust port 25 . The deodorizing filter laminate 1 is attached to the upper end portion of the housing body 21 by means of attachment portions 22 and 23 , and the fan 3 is attached below the deodorizing filter laminate 1 . Inside the housing 2, the fan 3 generates an air flow from the intake port 24 to the exhaust port 25, so that the air sucked from the intake port 24 passes through the deodorizing filter laminate 1 and is deodorized. It is exhausted from the exhaust port 25 .

The housing 2 is a member made of paper. For example, the housing main body 21 is formed by bending a piece of paper cut out along the folding lines into a cylindrical shape having a substantially rectangular cross section as shown in FIG. can be formed by pasting The mounting portion 22 is a rectangular paper material that is adhered to the inside of the housing body 21 , and the adhered mounting portion 22 serves as a protrusion inside the housing body 21 . As shown in FIGS. 2 and 3, the mounting portion 22 locks the mounting portion 23 inserted from the exhaust port 25 side, and the mounting portion 23 locks the deodorizing filter laminate 1 and the fan 3 . Since the housing 2 is a member made of paper, it can be manufactured easily and inexpensively without using a mechanical connection method, and can be disposed of as recyclable waste after use.

On the other hand, compared to a general plastic or metal housing, the housing 2 is less airtight and may reduce the deodorizing effect, but the deodorizing filter laminate according to one embodiment of the present invention It can be solved by applying 1. That is, by using the deodorizing filter layered body 1 in which gaps are provided between the filter portions 11 to enhance the deodorizing effect, it is possible to compensate for the reduction in the deodorizing effect due to the casing 2 being made of paper. In other words, in the case of the deodorizing filter laminate 1 according to the embodiment of the present invention, the housing 2 made of paper can be applied without reducing the deodorizing effect. It is possible to enjoy only

The housing 2 is not limited to the above-described mode, and the attachment positions and attachment methods of the deodorizing filter laminate 1 and the fan 3 can be changed as appropriate. For example, in FIGS. 2 and 3, the deodorizing filter layered body 1 and the fan 3 are attached close to each other, but they may be attached apart from each other. Alternatively, the deodorizing filter laminate 1 may be attached to the air inlet 24 side, and the fan 3 may be attached to the air outlet 25 side.
(Fan 3)

The fan 3 is a member that is attached to the housing 2 and generates an air flow from the intake port 24 of the housing 2 toward the exhaust port 25 . As a result, the air sucked from the intake port 24 passes through the deodorizing filter layered body 1 and is deodorized, and then exhausted from the exhaust port 25 . In addition, the aspect of the fan 3 is not specifically limited.
(Verification experiment on wind velocity of air passing through deodorizing filter laminate 1)

The inventor has confirmed by experiments that the wind speed of passing air increases by providing a gap between the filter portions 11 of the deodorizing filter laminate 1 according to one embodiment of the present invention. The content of the experiment will be described below.

In order to verify the wind speed of the air passing through the deodorizing filter laminate 1, the case where the three filter parts 11 are closely attached (pattern A) and the deodorizing filter in which the three filter parts 11 are arranged with a gap are provided. For the laminate 1 (pattern B), the wind speed V ₁ on the air inlet 24 side, the wind speed V ₂ on the air outlet 25 side, and the static pressure P between the filter unit 11 and the fan 3 were measured ten times each. See FIG. 6 for detailed measurement conditions.

When averaging the measured values 10 times, the wind speed V ₁ of pattern A is 0.509 ± 0.052 m / sec, the wind speed V ₂ is 0.286 ± 0.007 m / sec, the static pressure P is 9.0 ± 0 0 Pa. On the other hand, in Pattern B, the wind speed V1 was _0.535 ±0.028 _m /sec, the wind speed V2 was 0.345±0.009 m/sec, and the static pressure P was 9.5±0.0 Pa. Details of the measurement results are summarized in the table of FIG. In addition, when the Mann-Whitney U test was performed with a significance level of ₅ % for the wind speeds V1 and V2 of Pattern _A and Pattern _B , there was _no significant difference in the wind speed V1, and the wind speed V2 was significant. There was a difference.

From the above results, the deodorizing filter laminate 1 (pattern B) in which the three filter portions 11 are arranged with a gap is more effective than the case (pattern A) in which the three filter portions 11 are closely attached. It can be seen that the static pressure P between the portion 11 and the fan 3 increases and the wind speed on the exhaust port 25 side increases. That is, the amount of air pushed out to the exhaust port 25 side is increased, and the amount of air passing through the filter part 11 per unit time is increased. It can be said that the deodorizing effect is higher than when the part 11 is brought into close contact.

As described above, the deodorizing filter laminate 1 according to one embodiment of the present invention increases the amount of air passing through the filter portions 11 by providing a gap between the filter portions 11, and is installed in the deodorizing device. In this case, the deodorizing effect can be enhanced.
