In the figure, the indoor environment protection system comprises a recognition means 3 for recognizing a contaminant W to be adhered to or impregnated in the surface or interior of the interior material 1 or the interior article 2 of the indoor space R or a contaminant W diffused from the surface. And reducing means 4 for reducing the diffusion of the contaminant W recognized by the recognizing means 3 into the indoor space R.

In such a technical means, in the indoor space R, gaseous contaminants or particulate contaminants adhere to or impregnate the surface or the interior of the interior material 1 or the interior product 2. When these contaminants W diffuse into the indoor space R, there is a concern that the concentration of the contaminants will be high and the comfort of the indoor environment may be impaired. In this case, it is intended to recognize the contaminant W and to reduce the diffusion of the recognized contaminant W into the indoor space R.
Here, the interior material 1 widely includes a finishing material and a base material used for a floor, a wall, a ceiling, etc. that divides the indoor space R. In addition, the interior goods 2 are widely installed in the indoor space R and widely contain goods to decorate the room, and in this example, electric appliances (equivalent to air conditioners (air conditioners / air conditioners), fans, warm air heaters, lighting fixtures, pots , TVs, personal computers (Personal Computer), etc.).
The recognition means 3 may be a method of detecting the contaminant W with various sensors, or a method of sampling and extracting the contaminant W adhering or impregnated, and analyzing it appropriately, etc. No problem.
Furthermore, as long as the reduction means 4 is to reduce the diffusion of the pollutant W into the indoor space R, (1) a method for stopping the pollutant W on the surface or the inside of the interior material 1 etc. 2) There are methods such as a method of decomposing the pollutant W to be harmless and (3) a method of separating the pollutant W from the interior material 1 and the like and recovering the same.

Next, a representative aspect or a preferable aspect of the indoor environment protection system according to the present embodiment will be described.
First, as a preferred embodiment of the recognition means 3, besides the contaminant W, an embodiment that also recognizes a biological gas of a person staying in the indoor space R adhering to or impregnated on the surface or inside of the interior material 1 or the interior article 2 is mentioned. Be This example is an embodiment in which biogas of a person staying in the indoor space R is also adhered to and impregnated on the surface or inside of the interior material 1 or the interior article 2, so that biogas is also recognized in addition to the contaminant W. .
Moreover, as a typical aspect of the recognition means 3, it has a test chip which can be attached or detached to a part of the surface or the inside of the interior material 1 or the interior article 2, and the test chip is removed periodically or irregularly. There is an aspect in which the substance captured by the test chip is to be analyzed. In this example, a part of the interior material 1 and the part of the interior product 2 is provided with a removable test chip, and the contaminant W attached to the test chip can be analyzed by removing the test chip.

Furthermore, as a typical aspect of the reduction means 4, as shown in FIG. 1 (b), the characteristic that the contaminant W remains on the surface or inside of the interior material 1 or the interior article 2 or the contaminant W is decomposed Those which regularly or irregularly supply the drug 5 having In this example, the chemical substance 5 is supplied so that the contaminant W adhering to and impregnated into the interior material 1 does not diffuse into the indoor space R, and the contaminant W is retained (immobilized) or decomposed. It is a thing.
Moreover, as another representative aspect of the reduction means 4, as shown in FIG. 1 (c), the air flow 6 is periodically or irregularly supplied to the surface of the interior material 1 or the interior product 2 to provide the interior material 1. Alternatively, the contaminant W adhering to and impregnated on the surface or inside of the interior product 2 is eliminated, and the eliminated contaminant W is recovered. In this example, the air flow 6 generated in the indoor space R is used to desorb the contaminant W adhering to and impregnated into the interior material 1 or the like into the indoor space R, and this is recovered to the indoor space R. The diffusion of the pollutant W is reduced. Here, by supplying air flow 6 (preferably clean air) to the contaminated surface of the interior material 1 etc., a concentration gradient is produced on the boundary surface to promote detachment of the contaminant W adhering to the interior material 1 etc. and impregnated. , The emission rate of the pollutant W is increased, and the pollutant W is actively removed.

  Furthermore, as a specific example of the method shown in FIG. 1 (c), the contaminant W attached to or impregnated onto the surface or the interior of the interior material 1 or the interior article 2 so as to promote desorption of the contaminant W impregnated. On the other hand, there is an aspect having an air flow supply unit 7 for supplying the air flow 6 and a recovery unit 8 for recovering the separated contaminant W. This can be easily realized by generating a predetermined air flow pattern using the air flow supply unit 7 of this example, for example, an environmental device such as an air purification device, an air conditioner, or an air circulation device. What is necessary is to collect the separated contaminants W, and it can be easily realized by the cleaning filter in the air cleaning device or a dedicated recovery device.

Moreover, as a preferable aspect of the reduction means 4, the following can be mentioned.
In the first aspect, a useful substance capable of improving the surface functionality of the interior material 1 or the interior product 2 is included with respect to the medicine 5 or the air flow 6 supplied to the surface or inside of the interior material 1 or the interior product 2 It is. In this example, the treatment of the contaminant W is performed by including a useful substance capable of improving the surface functionality of the interior material 1 or the like to the chemical 5 and the air flow 6 supplied to the contaminant W. It is possible to improve the surface functionality of 1 grade and the like. The useful substance referred to here may be a gas phase (ozone, mist) or a liquid phase, or a photocatalyst or an electrically generated active species (such as plasma ion). In the case of the liquid phase, it may be penetrated through methods such as bake out, sprinkle, brush coating, press-in and the like.
The second aspect is one which is incorporated in advance into a part of an air purification device or other environmental equipment. In this example, in addition to the aspect in which the reduction means 4 is assembled to a part of the air purification apparatus, the aspect is assembled to environmental equipment other than the air purification apparatus, and a function of reducing pollutants W is added to the environmental equipment. It is a thing.

The third aspect uses the air flow 6 generated by an environmental device (corresponding to the air flow supply unit 7) installed in the indoor space R to adhere to and impregnate the interior material 1 or the interior product 2 with the contaminant W And the transported contaminant W along with the air flow 6 to the predetermined recovery unit 8 along the path of the air flow 6. In this example, the contaminant W adhering to and impregnated on the interior material 1 is desorbed using the air flow 6 of the environmental device, and the contaminant W desorbed together with the air flow 6 is transported to the recovery unit 8 It is
The fourth mode is an indoor combination of selected interior materials 1, interior items 2 and environmental equipment (not shown in FIG. 1) installed in the indoor space R when they are selected from a predetermined range. An indoor environment design tool capable of designing an environment is provided, and the indoor environment design tool has a function of predicting the degree of reflection of the reduction effect by the reduction means 4 on the designed indoor environment. In this example, when the user uses the indoor environment design tool and selects the interior material 1, the interior product 2, and the environmental device, the method of designing the indoor environment (air cleanliness, air flow, etc.) by a combination of selected ones is reduced. The reduction effect when employing the means 4 can be predicted.

The fifth aspect is a useful substance suitable for a person staying in the indoor space R, against the medicine 5 or the air flow 6 supplied to the contaminant W adhering to or impregnated on the surface or inside of the interior material 1 or the interior article 2 It is included. In this example, a useful substance suitable for a person staying in the indoor space R is used for the medicine 5 or the air flow 6 periodically or irregularly supplied to the contaminant W adhering to or impregnating the interior material 1 etc. If it is contained, useful substances suitable for humans will be periodically or irregularly dissipated to the surface of the interior material 1 or the interior goods 2, which is effective in further improving the maintainability of the indoor environment. is there.
Here, useful substances suitable for human beings include air with high oxygen concentration, which enhances the cleanliness of the air, and medical findings that reduce human comfort and immunity when a certain indoor environment is maintained for a long time In addition, it is also possible to dare to supply substances that lead to factors (temperature, humidity, air flow, illuminance, air cleanliness) that change the indoor environment in order to improve this.

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the attached drawings.
実 施 Embodiment 1
-Overall configuration of indoor environmental protection system-
FIG. 2 shows the entire configuration of the indoor environment protection system according to the first embodiment.
In the figure, in the indoor environment protection system, an indoor space R is divided by the interior material 20, and an air cleaner (air cleaning device) 30 is installed on a floor located in the indoor space R, for example, on the wall. Auxiliary fans 51 and 52 are installed on the ceiling and a part of the wall so that the clean air delivered from the air cleaner 30 circulates as the air flow Af along the interior material 20 of the indoor space R. Among them, the contamination treatment agent supply device 60 is installed on a part of the path of the air flow Af by the clean air from the air cleaner 30, for example, the floor on the wall opposite to the installation position of the air cleaner 30.

-Contaminants adhering to and impregnating interior materials-
Generally, in enclosed spaces such as buildings and moving bodies (cars, railways, ships, planes), gaseous substances (odorous substances, chemical substances, substances emitted from the interior material 20) and particulate substances (dust, tobacco smoke particles, It is necessary to take measures against microbial particles and dust generation from the interior material 20, and there is also a concern about dust generation from the interior material 20 and air pollution due to the released material.
For example, in houses, re-emission of substances (odorous substances, chemicals, microorganisms ...) attached to coated walls such as diatomaceous earth and dust generation of diatomaceous earth itself, similar re-emission and SVOC (semi-volatile organic compounds, Plasticizer) dissipates. There is a demand to suppress the re-emission and the emission of dust such as dust of the building materials themselves, and the emission of chemical substances and odorous substances. Furthermore, in the diatomaceous earth wall, there is a problem of odorant contamination due to re-emission of the gas once captured, and scattering of diatomaceous earth and the mixture into the indoor space R, and odor contamination of the diatomaceous earth finish used for a long time and dusting from building materials themselves. The dust concentration tends to rise, and there is a demand to suppress this.
In the present embodiment, a substance that may contaminate the indoor space R is referred to as a contaminant W, and a substance that treats it is referred to as a contamination treatment agent.

-Specific treatment of pollutants-
In this example, as shown in FIG. 2, a removable test chip 21 is provided on a part of the interior material 20. Generally, the area of the interior material 20 that divides the indoor space R is large, and as described above, the interior material 20 contains a large amount of chemical substances, gaseous substances such as odor, dust, tobacco smoke particles, mites, mold, pollen And so on, so that the test chip 21 which is a part of the interior material 20 is removed, and the contaminant (gaseous substance, particulate matter) attached to the test chip 21 by the contaminant analysis device 70 By analyzing W, it is possible to identify the contaminant W specific to the indoor space R.
In this example, as the contaminant analysis device 70, known analysis methods such as a gas chromatograph, a gas chromatograph mass spectrometer, a high performance liquid chromatograph, an ion chromatograph and the like are employed.
In the present embodiment, the detachable test chip 21 is provided on a part of the interior material 20, but the present invention is not limited to this, and one of the interior accessories not shown installed in the indoor space R The test chip may be provided with a detachable test chip (not shown), and the test chip may be removed and the contaminant attached to the test chip may be analyzed by the contaminant analyzer 70.

-Selection processing of contamination treatment agents-
As described above, when the analysis result of the contaminant W attached to the test chip 21 is obtained by the contaminant analysis device 70, the contamination treatment agent Q suitable for processing the contaminant W from the contamination treatment agent selection device 80 Is selected.
In this example, the contamination treatment agent selection apparatus 80 has a database in which the contamination treatment agent Q effective in treating various contaminants is registered in advance, and the user (here, the contamination treatment agent selection person) is the processing object By inputting the contaminant W which becomes the effective contamination treating agent Q is listed from the database, the appropriate contamination treating agent Q is selected from among them.
The contamination treatment agent Q in this example is selected from the following selection criteria (1) or (2) as shown in FIG. In FIG. 2, reference numeral 22 denotes a functional layer covering the surface of the interior material 20 (for example, a functional layer intended for deodorizing, chemical substance removability, humidity control, and dust resistance).

(1) As the contamination treatment agent Q (I), one that acts so as to retain the contaminant W adhered to or impregnated on the surface or the inside of the interior material 20 is selected. As a representative example of this type of contamination treatment agent Q (I), in principle, a solution or gas sprayed on the interior material 20 is a contamination that adheres to or is impregnated on the interior material 20 by a chemical reaction or decomposition. The substance W may be made to contain a substance to be stabilized.
(2) As the contamination treatment agent Q (II), one that acts so as to decompose the contaminant W adhering to or impregnated on the surface or the inside of the interior material 20 is selected. As a representative example of this type of contamination treatment agent Q (II), in principle, a solution or gas sprayed on the interior material 20 is a contamination that adheres to or is impregnated on the interior material 20 by a chemical reaction or decomposition. It may be made to contain the substance which substance W decomposes.

<Treatment example 1 with the contamination treatment agent Q>
FIGS. 3 (a) to 3 (c) show an indoor environment protection system using a gas phase of ions or active species (OH radicals, ozone, etc.) as the contamination treatment agent Q.
Now, in FIG. 3 (a), the contamination treatment agent supply device 60 supplies ions (active species) 101 as the contamination treatment agent Q. For example, the ions as the contamination treatment agent Q (active species) are directed upward. It is supposed to blow out 101.
At this time, as shown in FIG. 3 (b), when the ion (active species) 101 as the contamination treatment agent Q blown out from the contamination treatment agent supply device 60 is supplied to the wall surface of the interior material 20, The active species 101 acts on the surface of the interior material 20 so as to be odorless, adsorbed, decomposed or immobilized with respect to the impregnated contaminants W to render them harmless.
In particular, in the present embodiment, the clean air blown out from the air cleaner 30 flows along the floor surface toward the contamination treatment agent supply device 60, and the auxiliary fan 51 installed on the ceiling and side wall of the indoor space R, The air flows along the air flow Af circulating from one side wall surface of the indoor space R along the ceiling surface toward the other side wall surface by the air flow 52 and is blown out again via the air purifier 30. Therefore, the ions (active species) as the contamination treatment agent Q blown out from the contamination treatment agent supply device 60 circulate along the floor surface of the indoor space R, one side wall surface, the ceiling surface, and the other side wall surface. And capture the contaminants W floating in the indoor space R while being widely supplied to the wall surfaces of the interior material 20, and adhere to the wall surfaces of the interior material 20, thereby detoxifying the contaminants W.

<Treatment example 2 with the contamination treatment agent Q>
FIGS. 4 (a) to 4 (c) show an indoor environment protection system using a useful substance as the pollution control agent Q. FIG.
Now, in FIG. 4 (a), the contamination treating agent supply device 60 supplies the useful substance 102 in the liquid phase as the contamination treating agent Q, and for example, spraying upward the useful substance 102 as the contamination treating agent Q It is supposed to blow out in the form of Here, the useful substance 102 is appropriately selected according to the contaminant W. For example, when the contaminant W is formaldehyde, a formaldehyde catcher agent is selected as the useful substance 102.
Then, as shown in FIG. 5A, for example, the principle of supply of the useful substance 102 by the contamination treatment agent supply device 60 is that the pump unit 63 uses the chemical solution from the chemical solution bottle 61 in which the chemical solution containing the useful material 102 is contained. A fixed amount is drawn up and sprayed from the nozzle 64 periodically.
Here, the supply principle of the useful substance 102 by the contamination treatment agent supply device 60 is not limited to this, and for example, as shown in FIG. 5B, the flow control valve 66 and the air supplied from the air pump 65 There is no problem in adopting a method of throttling to a predetermined flow rate with the flow meter 67, guiding it to the drug solution in the drug solution bottle 61 through the filter 68, and periodically spraying it from the nozzle 64, etc. As shown in FIG. 5, the nozzle 64 may be swingably supported via a swing mechanism 69, and the chemical solution may be sprayed in a more diffused state toward the air flow Af circulating in the indoor space R.
In the present embodiment, although the system for automatically supplying the useful substance 102 is adopted as the contamination treatment agent supply device 60, the present invention is not limited to this, and a manual type contamination treatment agent supply device 90 is used You may As this type of manual contamination processing agent supply device 90, for example, the chemical solution in the chemical solution bottle 91 is guided to the manually operable spray nozzle 93 through the tube 92, and the spray range of the chemical solution blown out from the spray nozzle 93 is set. What was made to regulate with spray area control hood 94 is mentioned. When using this example, the user may spray the chemical solution sequentially while moving the spray area regulation hood 94 to the wall surface of the interior material 20 as appropriate.

Also in this embodiment, as shown in FIG. 4 (b), when the useful substance 102 as the contamination treatment agent Q blown out from the contamination treatment agent supply device 60 is supplied to the wall surface of the interior material 20, the useful substance 102 is delivered. Acts on the contaminant W attached to the surface of the interior material 20 so as to be odorless, adsorbed, decomposed, or immobilized to render it harmless.
In particular, in the present embodiment, since the chemical solution containing the useful substance 102 is supplied to the wall surface of the interior material 20 in a spray form, the contamination permeating the interior of the interior material 20 compared to the case where the gas phase useful material is used. It is effective in detoxifying the substance W.
That is, in the aspect in which the vapor phase useful substance (for example, ozone) is supplied to the surface of the interior material 20, the removal effect is reduced when the contaminant penetrates the deep layer inside the interior material 20. For example, in the situation where any odor-generating substance penetrates into the interior material 20 in the liquid phase, even if the useful substance is supplied in the gas phase, the permeability is limited. In this regard, if the liquid phase useful substance 102 is used, it is possible to allow the useful substance 102 to penetrate to the inner deep layer of the interior material 20. In particular, in order to effectively permeate the useful substance 102 in the liquid phase, the object heating method (in order to improve the absorptivity of the useful substance 102, the internal water content of the interior material 20 is reduced It is preferable to be combined with a bake-out method (in which the temperature is raised), a pressure method in which the spray pressure of the useful substance 102 is set high, and the like. In addition, when using the manual type pollution control agent supply apparatus 90, it is preferable to actively sprinkle or brush the useful substance 102 with respect to the location which the useful substance 102 of a liquid phase runs short.

  Moreover, in this example, there is a concern that another substance may be dissipated along with the decomposition of the contaminant W adhered to and impregnated on the wall surface of the interior material 20, particularly because the useful substance 102 in the liquid phase is used. Since substances are carried by the air flow Af and returned to the air purifier 30, if the cleaning filter 40 of the air purifier 30 is provided with a recovery function of the substance to be dissipated, these substances are able to clean the air purifier 30. It can be collected by the filter 40. When the useful substance in the gas phase is used, or when the ion (active species) 101 of Treatment Example 1 is used, even if the substance accompanying the decomposition of the contaminant W is diffused, it is the same as described above. The emission material may be recovered by the cleaning filter 40 of the air purifier 30.

<Functional Recovery of Interior Materials>
Further, in the present embodiment, as shown in FIG. 2, the interior material 20 is provided with a predetermined functional layer 22 such as the function of purifying indoor air (for example, the function of adsorbing and decomposing pollutants). It is inevitable that the performance of the functional layer 22 will be degraded along with it.
At this time, if a component effective for recovering the functional layer 22 of the interior material 20 is included in the contamination treatment agent Q, the contamination treatment agent Q is supplied to the surface of the interior material 20, thereby causing contamination. In addition to the treatment of the substance W, it is also possible to periodically restore the performance of the functional layer 22 of the interior material 20.

According to the figure, the following results were obtained.
(1) The detected odor pollutants include those belonging to aldehydes and fatty acids.
(2) When the chemical substance generation amount of tatami mat and wallpaper collected from the measurement target room was determined by the chamber test, the same odor substance as indoor air pollutants was detected from the mat, and the odor substance emitted from the remains was identified Chemical materials were obtained.
(3) The causative substance could be effectively identified by adding the heating operation (bak out) to the odorous substance generation source. In addition, an increase in the amount of odorous substances generated from odorant sources due to bakeout has been confirmed, and if a countermeasure (for example, air cleaning treatment with an air purifier) is adopted to remove this, the odorous substances from odorant sources Was found to be effective in reducing the amount of
(4) The adsorption amount from the source of odorous substances (tatami) to the wallpaper (vinyl cloth) was small.
Thus, in the present embodiment, it is an object of the present invention to solve the problem of odor contamination in a short period of time in an accident property in a house (e.g. a property in which a dead body is left behind due to loneliness death and odor is perceived indoors). It has been confirmed that the use of a bake out or an air cleaner is effective in eliminating odor generation in a short period of time.
