DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an odor and harmful gas removing device for removing bad odor components and harmful gas components in a building.

[0002]

2. Description of the Related Art In recent years, in addition to changes in housing styles, due to dirt in the open air and the like, many people have been unable to open their windows.
For example, odors such as toilet odor, garbage odor, tobacco odor, body odor, pet odor and the like, as well as odors and harmful gases generated from indoor building materials and linings have become problems.

[0003] As means for removing such odors and harmful gases,
Ventilation with outside air is most commonly performed. However, in an urban area where air pollution is severe due to the increase in automobiles and the like, dirty air may enter the room due to ventilation with outside air.

[0004] For this reason, an odor and harmful gas removing device capable of adsorbing and removing an odor and a harmful gas in a room has been developed and used.

[0005]

However, most of the odor and harmful gas removal devices conventionally used generally utilize the adsorption power of activated carbon, and there is a limit to the adsorption of odor and harmful gas by this activated carbon. However, there is a problem that it has not yet been satisfied.

With the above structure, when a ventilation means such as an electric fan is provided in the housing to suck and exhaust indoor air and forcibly circulate the indoor air, a hydrophilic group and a hydrophilic group are used as the functional groups having the ability to adsorb polar substances on the substrate. A macromonomer containing a cationic dissociative group and / or an anionic dissociative group contains an adsorbent material that is bonded by graft polymerization, so that the odor components and harmful gas components of the indoor air can be efficiently converted into the adsorbent material. It can be adsorbed and removed well and is effective for deodorizing indoor air.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of an odor and harmful gas removing apparatus according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a main part of an apparatus 1 according to a first embodiment used as an indoor unit. By rotating an electric fan 40 which is a blowing means housed in a case 2, it is operated by rotating the electric fan 40. Intake air A through the case 2
Exhaust and forced circulation. Case 2
Is provided with, for example, a slit-shaped intake port 3 for inhaling and taking in the room air A in the lower bottom plate in the figure as viewed from the top and bottom, and the upper top plate is deodorized and returned to the room. Slit-shaped exhaust port 4 is provided.

In such a case 2, for example, three types of first, second, and third suction portions 10, 20, and 30 having different forms and functions are arranged in several stages from the lower side to the upper side.

The lowermost first suction section 10 is arranged in the vicinity of the intake port 3 and has a mesh bag container 12 carried on a filter-shaped mounting rack 11 which can be ventilated. The net bag container 12 has an adsorbent material 1 in which a macromonomer is bonded to a granular material serving as a base by graft polymerization.
3 are accommodated.

In the second suction section 20 in the middle stage, a dished container 22 with a bottom is supported on a mounting rack 21 in the form of a filter that can be ventilated. The dish-shaped container 22 contains an adsorbent material 23 in which a macromonomer is bonded to a liquid material serving as a base by graft polymerization.

Further, in the uppermost third suction section 30, a cylindrical container 32 having a bottom is supported on a mounting rack 31 in the form of a filter which can be ventilated. The cylindrical container 32 contains an adsorbing material 33 in which a macromonomer is bonded to a gel-like substance serving as a base by graft polymerization.

The first, second, and third suction portions 10, 2
An electric fan 40 is arranged above the air outlets 0 and 30 so as to face the exhaust port 4.
The motor 41 is connected to a (volt) home power supply, and the motor 41 that is supplied with electric power is driven to rotate the blades 42 to generate an airflow from the intake port 3 to the exhaust port 4.
By such an air flow, evaporation of the liquid adsorbing material 23 in the second adsorbing section 20 and the gel-like adsorbing material 33 in the third adsorbing section 30 are promoted.

Here, each of the above adsorbing materials 13, 23, 3
The macromonomer used in 3 includes a hydrophilic group, a cationic dissociation group, and / or a functional group capable of adsorbing a polar substance such as an odor component or a harmful gas component in room air A.
Or it contains an anionic dissociating group.

The hydrophilic group having adsorptive power contained in the macromonomer is a group (nonion) which has an affinity for water and does not dissociate ions when contacted with water. Such a hydrophilic group can capture moisture present in the air, and the captured water molecules are adsorbed on the surface of the substrate to form an aqueous layer, dissolve the polar substance, and dissociate the ionic substance. You will be sick. Such hydrophilic groups include, for example, hydroxyl, hydroxyalkyl and pyrrolidonyl groups.

The cationic dissociative group having the same adsorptive capacity refers to an ion exchange group whose counter ion is a cation, and is an acid group. The cationic dissociating group has a capability of adsorbing a polar substance, can release hydrogen ions and can undergo a neutralization reaction with a basic substance, and as a result, the basic substance is removed. Such cationic dissociating groups include, for example, carboxyl, sulfone, phosphate, sulfoethyl, phosphomethyl and carbomethyl groups.

An anionic dissociating group having the same adsorptivity means an ion-exchange group whose counter ion is an anion, which has an ability to adsorb a polar substance and can neutralize with an acidic substance. As a result, acidic substances will be removed. Such anionic dissociating groups include, for example, 1 to
There are tertiary amino groups and quaternary ammonium groups.

Incidentally, there are various odor components and harmful gas components, and they are generally combined. The adsorption of these gas components by the above-mentioned ion exchange groups is chemical adsorption, and unlike activated carbon of physical adsorption, the once adsorbed components can be reactivated by changes in operating conditions such as temperature / pressure changes and start / stop. However, it is difficult to remove any gas other than the acidic gas and the basic gas. For example, neutral harmful gas components such as acetaldehyde and formaldehyde cannot be removed simply by contacting the ion-exchange groups with a substrate carrying the macromonomer by bonding. In this case, a substance having an amino group or the like is further supported on the substrate. This makes it possible to remove not only acidic gas and basic gas but also neutral harmful gas components.

Next, the operation and operation of the apparatus 1 according to the first embodiment having the above configuration will be described.

When the electric fan 40 is turned on, the room air A drawn from the intake port 3 of the case 2 and taken in.
By contacting the adsorbing material 13 in the first adsorbing section 10, odor components and harmful gas components are adsorbed and removed. The room air A thus deodorized is discharged from the exhaust port 4 as "deodorized air a" and returned to the room.

The indoor air A that has not been completely deodorized in the first adsorbing section 10 contacts the adsorbing material 23 in the dish-shaped container 22 in the second adsorbing section 20 and is deodorized. On the other hand, the room air A sucked from the air inlet 3 and reaching the second adsorbing section 20 comes into contact with the adsorbing material 23 in the dish-shaped container 22 while holding and transporting the evaporated component. The air is exhausted from the exhaust port 4 as “adsorbent holding air b” and returned to the room. The adsorbent holding air b returned to the room adsorbs odor components and harmful gas components floating in the room to the carried adsorbent material 23 to deodorize. In this way, the adsorbent holding air b that has adsorbed and held the odor and the like in the room is again taken into the case 2 from the intake port 3 and repeats the above-described operation.

Further, the third adsorbing section 30 is supplied with the room air A that has not been completely deodorized in the first and second adsorbing sections 10 and 20.
At this time, it comes into contact with the adsorbing material 33 in the cylindrical container 32 and is deodorized. On the other hand, the room air A sucked from the air inlet 3 and reaching the third adsorbing section 30 comes into contact with the adsorbing material 33 in the cylindrical container 32 and retains and transports the evaporated components while exhausting the air. The air is exhausted from the port 4 as “adsorbent holding air c” and returned to the room. Also in this case, the adsorbent holding air c returned into the room desorbs the odor component and the harmful gas component floating in the room by the carried adsorbent material 23 and deodorizes it. The adsorbent holding air c that has thus adsorbed and held the odor and the like in the room is again taken into the case 2 from the intake port 3 and repeats the above-described operation.

As described above, the room air A containing the odor component and the harmful gas component is forcibly circulated between the room and the case 2, so that the room can always be maintained in a comfortable space.

The present invention is not limited to the above-described first embodiment, but may be applied to some applications such as the following second embodiment.

First, as the odor and harmful gas removing device according to the second embodiment of the present invention, a plurality of different kinds of granular materials and liquid materials in the first, second, and third adsorption sections 10, 20, and 30 are provided. The adsorbents 13, 23, and 33 can be formed by using a gel-like substance as a substrate and bonding “heterogeneous” macromonomers to each other. As will be confirmed once again, in the first embodiment, the adsorbent material 1 in which a plurality of different kinds of granules, liquids, and gels are respectively combined with “the same type” of macromonomer.
3, 23, 33. In the second embodiment, the heterogeneous macromonomer may be one in which a heterogeneous functional group is bonded to one of them. There is no particular limitation on the bonding pattern.

In these first and second embodiments, the first, second and third suction portions 10, 20, 30 as shown in FIG.
The number of arrangements and the arrangement order are merely examples, and the number of arrangements can be increased or decreased, and the arrangement order can be changed.

Next, as a third embodiment according to the present invention, instead of the electric fan 40 shown in FIG. 1 used as a blowing means, air is introduced into the case 2 using the principle of ultrasonic vibration. A device for generating a flow can be used as the blowing means. The power supply is not limited to a household power supply having a voltage of 100 V, and a rechargeable battery or a simple dry battery may be mounted in the case 2 and used.

Further, as a fourth embodiment according to the present invention, an ultrasonic vibration device is arranged in the vicinity of the dish-shaped container 22 particularly in the second suction section 20, and a vibration is applied to the suction material 23 by ultrasonic waves. It is also possible to evaporate positively. Further, in the second adsorbing section 20, a fragrance having a pleasant scent may be added to the adsorbing material 23 as an application example, or the fragrance may be independently arranged beside the adsorbing material 23. . As a result, the room air A taken into the case 2 comes into contact with the adsorbent material 23 and the fragrance, so that not only the adsorbent holding air b as described above, but also the indoor air Can be returned to. Thereby, the second adsorbing section 20 can have both the deodorizing function and the fragrance function, which is effective for sending out the fragrance into the room to create a healing space.

In each of the above embodiments, the case where the odor and harmful gas removing device 1 is used as an indoor unit to forcibly circulate the indoor air A has been described. It is not limited to a device for forced circulation.
For example, it may be installed on a wall surface to exhaust the bad smell and unpleasant odor of the indoor air to the outside, or to take in fresh air from outside.

[0037]

As described above, the odor and harmful gas removing apparatus according to the first aspect of the present invention is provided with a fan in a housing to suck and exhaust indoor air and to forcefully circulate the air. As a functional group having the ability to adsorb polar substances,
Since the macromonomer containing a hydrophilic group and a cationic dissociating group and / or an anionic dissociating group contains an adsorbing material bound by graft polymerization, the odor component and the harmful gas component of the indoor air are reduced. It can be efficiently adsorbed to the adsorbing material and removed, which is effective for deodorizing indoor air.

Further, the odor and harmful gas removing apparatus according to the present invention according to the second aspect of the present invention is characterized in that the adsorbing material is constituted by a plurality of substrates of the same type to which macromonomers having different functional groups are bonded. Accordingly, there is an advantage that various harmful components in the indoor air can be adsorbed in several stages, and the deodorizing effect of the indoor air is further promoted.

The odor and harmful gas removing apparatus according to the present invention according to the third aspect of the present invention is the same as the second aspect by combining a plurality of different types of substrates as the adsorbing material. By adsorbing various harmful components in the indoor air over several stages, the deodorizing effect of the indoor air can be further enhanced.
