Description

The present invention relates to an exhibition device that shows the mechanism for reducing the concentration of chemical substances in the indoor space of a building.

Technologies for adjusting the air environment in indoor spaces of buildings such as houses and condominiums have been known for some time. However, it is difficult to get a real sense of how effective such technologies are in adjusting the air environment in indoor spaces. Therefore, exhibition facilities have been proposed to allow visitors to recognize the state of the air environment in indoor spaces (see, for example, Patent Document 1).

The exhibition facility disclosed in Patent Document 1 is equipped with a ventilation experience device and a heat exchange experience device. This exhibition facility allows visitors to recognize the ventilation state inside a model house using the ventilation experience device, and allows visitors to experience the air temperature using the heat exchange experience device.

In recent years, however, there has been a demand for the air environment in the indoor spaces of buildings to be one in which the concentrations of chemical substances thought to be causative of, for example, sick house syndrome are reduced. For this reason, there is room for improvement in exhibition facilities in terms of enabling visitors to recognize the mechanisms for reducing the concentrations of chemical substances in the indoor spaces of buildings.

The present invention was made in consideration of these circumstances, and its purpose is to provide an exhibition device that can help visitors understand the mechanism for reducing the concentration of chemical substances in the indoor space of a building.

The exhibition device according to one aspect of the present invention is a device that shows a mechanism for reducing the concentration of chemical substances in an indoor space of a building. This exhibition device includes a first building model including a first model body that defines a first simulated indoor space having an intake port and an exhaust port, and a first ventilation mechanism for ventilating the first simulated indoor space, a second building model including a second model body that defines a second simulated indoor space having an intake port and an exhaust port, and a second ventilation mechanism for ventilating the second simulated indoor space, and a substance visualization body that is arranged in the first simulated indoor space and the second simulated indoor space and visualizes and shows the chemical substances. The ventilation volume of the first ventilation mechanism is set to a value larger than the ventilation volume of the second ventilation mechanism. The substance visualization body is configured to be movable in response to ventilation by at least the first ventilation mechanism of the first and second ventilation mechanisms, and includes multiple types of visualization bodies having different characteristics for multiple types of sources of the chemical substances provided in the first and second simulated indoor spaces, and at least the first building model of the first and second building models includes a collection unit that moves within the first simulated indoor space in response to ventilation by the first ventilation mechanism and separates and collects the substance visualization bodies by type that are discharged from the exhaust port.

According to this exhibition device, the building models are provided with a first building model having a first simulated indoor space and a second building model having a second simulated indoor space, and a substance visualization body that visualizes chemical substances. The first building model includes a first ventilation mechanism for ventilating the first simulated indoor space, and the second building model includes a second ventilation mechanism for ventilating the second simulated indoor space. In this case, the ventilation volume of the first ventilation mechanism is set to a value larger than the ventilation volume of the second ventilation mechanism, and the substance visualization body is configured to be movable in response to ventilation by at least the first ventilation mechanism of the first and second ventilation mechanisms.

In this configuration, the substance visualization object arranged in the first simulated indoor space is moved by the first ventilation flow generated in the first simulated indoor space in response to ventilation by the first ventilation mechanism. On the other hand, the substance visualization object arranged in the second simulated indoor space is moved by the second ventilation flow generated in the second simulated indoor space in response to ventilation by the second ventilation mechanism, or is not moved by the second ventilation flow. Even if the substance visualization object moves by the second ventilation flow, the ventilation volume of the first ventilation mechanism is larger than the ventilation volume of the second ventilation mechanism, so that the movement speed of the substance visualization object in the first simulated indoor space is faster than the movement speed of the substance visualization object in the second simulated indoor space. Since it is possible to visually allow the visitor to recognize such a difference in the movement speed of the substance visualization object, it is possible to visually allow the visitor to recognize that a difference occurs in the emission speed of chemical substances from the indoor space depending on the difference in the ventilation structure between the first ventilation mechanism and the second ventilation mechanism. In particular, by placing different types of substance visualization bodies for each chemical substance source in the first and second simulated indoor spaces at predetermined positions in each simulated indoor space, visitors can visually recognize the process from chemical substance generation to emission. As described above, by using the exhibition device, it is possible to allow visitors to the exhibition device to visually recognize the mechanism for reducing the concentration of chemical substances in the indoor space of a building.

Moreover, in the exhibition device, as a configuration for collecting multiple types of substance visualization objects, at least the first building model of the first building model and the second building model includes a collection section. This allows the substance visualization objects that move within the first simulated indoor space due to the first ventilation flow generated within the first simulated indoor space in response to ventilation by the first ventilation mechanism to be separated by type and collected using the collection section. This allows the substance visualization objects that have moved within the first simulated indoor space to be efficiently returned to their designated positions.

In the above-mentioned exhibition device, the first model body has a first emission amount regulating material made of a building material having an emission amount of the chemical substance equal to or less than a predetermined standard emission amount and arranged to face the first simulated indoor space, and a first adsorption amount regulating material made of a building material having an adsorption amount of the chemical substance equal to or more than a predetermined standard adsorption amount and arranged to face the first simulated indoor space. The second model body has a second emission amount regulating material made of a building material having an emission amount of the chemical substance exceeding the standard emission amount and arranged to face the second simulated indoor space, and a second adsorption amount regulating material made of a building material having an adsorption amount of the chemical substance less than the standard adsorption amount and arranged to face the second simulated indoor space. The substance visualization bodies are arranged in each simulated indoor space so that the number of the substance visualization bodies arranged in the first simulated indoor space is less than the number of the substance visualization bodies arranged in the second simulated indoor space.

In this embodiment, the first building model and the second building model are each made using a material that determines the amount of chemical substance emission different from that of chemical substance emission, and a material that determines the amount of chemical substance adsorption different from that of chemical substance absorption. Therefore, the concentration of chemical substances differs between the first simulated indoor space of the first building model and the second simulated indoor space of the second building model. In other words, the first simulated indoor space of the first building model, which includes a first material that determines the amount of chemical substance emission with a small amount and a first material that determines the amount of chemical substance adsorption with a large amount, has a lower concentration of chemical substances than the second simulated indoor space of the second building model. As a result, a difference in odor caused by chemical substances occurs according to the difference in concentration of chemical substances between the first simulated indoor space and the second simulated indoor space, and based on the difference in odor, it is possible to olfactorily recognize that the amount of chemical substance emission and the amount of chemical substance adsorption in the building materials used in the construction of the building are related to the concentration of chemical substances in the indoor space.

Moreover, the substance visualization objects can visualize the difference in concentration of chemical substances between the first and second simulated indoor spaces by the number of substance visualization objects arranged in each space. In other words, since the first simulated indoor space has a lower concentration of chemical substances than the second simulated indoor space, in this case the number of substance visualization objects arranged in the first simulated indoor space is made smaller than the number of substance visualization objects arranged in the second simulated indoor space. Based on this difference in the number of substance visualization objects arranged between the first and second simulated indoor spaces, it is possible to visually recognize that the amount of chemical substances emitted and adsorbed in the building materials used in the construction of a building is related to the concentration of chemical substances in the indoor spaces.

In the above-mentioned display device, the first model body has a first support part that removably supports the first emission amount determining material and the first adsorption amount determining material, and the second model body has a second support part that removably supports the second emission amount determining material and the second adsorption amount determining material, respectively.

In this aspect, in the first building model, the first emission amount determining material and the first adsorption amount determining material are detachable from the first support part. For example, when the concentration of the chemical substance in the first simulated indoor space changes due to changes over time, the first emission amount determining material and the first adsorption amount determining material can be replaced by attaching and detaching the first emission amount determining material and the first adsorption amount determining material to and from the first support part. On the other hand, in the second building model, the second emission amount determining material and the second adsorption amount determining material are detachable from the second support part. For example, when the concentration of the chemical substance in the second simulated indoor space changes due to changes over time, the second emission amount determining material and the second adsorption amount determining material can be replaced by attaching and detaching the second emission amount determining material and the second adsorption amount determining material to and from the second support part.

In the above-mentioned display device, the first model body has a floor surface, the exhaust port of the first model body is provided at a position capable of receiving the substance visualization body moving along the floor surface, and the recovery unit is disposed at a position below the floor surface.

In addition, in the above-mentioned exhibition device, the substance visualization objects have the characteristic that their sizes differ depending on the type, and the recovery section has a multi-layer structure in which multiple recovery sections are stacked to be able to recover the substance visualization objects according to size, and in the multiple recovery sections, except for the bottommost recovery section, holes are formed that allow the substance visualization objects to pass through, and the diameter of the holes is larger in the recovery sections located higher up.

In this embodiment, the collection section is disposed outside the first simulated indoor space at a position below the floor surface. Therefore, the substance visualization objects moving along the floor surface due to the first ventilation flow generated in the first simulated indoor space in response to ventilation by the first ventilation mechanism fall from the exhaust port toward the collection section. The collection section can receive the substance visualization objects falling from the exhaust port and separate and collect them by type in the multiple-stage collection section.

In the above display device, the first model body has an internal space capable of accommodating the substance visualization object, and includes a first simulated wall structure having a first substance outlet that opens the internal space and a first lid that opens and closes the first substance outlet, and allows the substance visualization object to be discharged into the first simulated indoor space by opening the first substance outlet with the first lid. The second model body has an internal space capable of accommodating the substance visualization object, and includes a second simulated wall structure having a second substance outlet that opens the internal space and a second lid that opens and closes the second substance outlet, and allows the substance visualization object to be discharged into the second simulated indoor space by opening the second substance outlet with the second lid.

In this embodiment, in the first building model, the first substance outlet is opened by the first lid, and the substance visualization body disposed inside the first simulated wall structure is discharged into the first simulated indoor space through the first substance outlet. Meanwhile, in the second building model, the second substance outlet is opened by the second lid, and the substance visualization body disposed inside the second simulated wall structure is discharged into the second simulated indoor space through the second substance outlet. This discharge of the substance visualization body into the first and second simulated indoor spaces allows visitors to recognize that chemical substances are being released from inside the wall structures in an actual building.

In the above-mentioned exhibition device, the first building model includes a first ventilation visualization unit that visualizes the ventilation volume of the first ventilation mechanism, and the second building model includes a second ventilation visualization unit that visualizes the ventilation volume of the second ventilation mechanism.

In this aspect, the difference in ventilation volume between the first ventilation mechanism and the second ventilation mechanism is visualized by the first ventilation visualization unit and the second ventilation visualization unit. This allows the difference in ventilation volume between the first ventilation mechanism and the second ventilation mechanism to be visually recognized.

As described above, the present invention provides an exhibition device that allows visitors to understand the mechanism for reducing the concentration of chemical substances in the indoor space of a building.

The following describes an exhibition device 1 according to one embodiment of the present invention with reference to Figures 1 to 5. Note that directional relationships will be described below using the up-down direction, the front-back direction, and the left-right direction. The up-down direction refers to the vertical direction, the front-back direction refers to a direction on a horizontal plane perpendicular to the up-down direction, and the left-right direction refers to a direction on a horizontal plane perpendicular to the front-back direction.

The exhibition device 1 according to this embodiment is a device used to make visitors to the exhibition device 1 aware of the mechanism for reducing the concentration of chemical substances in the indoor space of a building such as a house or condominium. Examples of chemical substances in the indoor space of a building include volatile organic compounds such as toluene, xylene, and formaldehyde.

The exhibition device 1 comprises a first building model 2 and a second building model 3 that imitate buildings, and a substance visualization body 4 that shows chemical substances as visualized H. In the exhibition device 1, a first simulated indoor space S1 having a first concentration of a chemical substance is reproduced by the first building model 2, and a second simulated indoor space S2 having a second concentration of a chemical substance that is higher than the first concentration is reproduced by the second building model 3. The difference in concentration of the chemical substance between the first simulated indoor space S1 of the first building model 2 and the second simulated indoor space S2 of the second building model 3 is visualized using the substance visualization body 4, thereby allowing visitors to recognize the mechanism for reducing the concentration of chemical substances in the indoor spaces of buildings.

As shown in FIG. 2, the first building model 2 includes a first model body 21, a first simulated floor material 22, a first simulated wall material 23, and a first simulated furniture 24.

The first model body 21 constitutes the main body of the first building model 2. The first model body 21 is formed in a rectangular box shape by a pair of first simulated wall structures 211a, 211b, a front wall portion 212, a rear wall portion 213, a bottom wall portion 214, and a top wall portion 215.

The pair of first simulated wall structures 211a, 211b imitate the walls of a building, have surfaces extending in the vertical and front-to-rear directions, and are arranged opposite each other with a gap in the left-to-right direction. The front wall portion 212 is a plate-shaped wall connected to the front ends of the pair of first simulated wall structures 211a, 211b in the front-to-rear direction. The rear wall portion 213 is a plate-shaped wall connected to the rear ends of the pair of first simulated wall structures 211a, 211b in the front-to-rear direction. The bottom wall portion 214 is a plate-shaped wall connected to the lower ends of the pair of first simulated wall structures 211a, 211b in the vertical direction. The top wall portion 215 is a plate-shaped wall attached to the upper ends of the pair of first simulated wall structures 211a, 211b in the vertical direction so as to be able to rotate around a rotation axis 2151 extending in the left-to-right direction. The top wall 215 opens or closes the first simulated indoor space S1 by rotating around the rotation axis 2151. The front wall 212 and the top wall 215 are made of transparent materials so that the state inside the first simulated indoor space S1 can be seen.

In the first model body 21, the rear end portion of the pair of first simulated wall structures 211a, 211b is provided with the first wall material support portion 2131 in front of the rear wall portion 213 with the rear wall portion 213 connected. The first wall material support portion 2131 is a portion of the first model body 21 that detachably supports the first simulated wall material 23. The first simulated wall material 23 is an example of a first adsorption amount regulation material arranged to face the first simulated indoor space S1. The first simulated wall material 23 is a plate-shaped wall material composed of a building material having an adsorption amount of a chemical substance equal to or greater than a predetermined standard adsorption amount. Specifically, the first simulated wall material 23 is a wall material in which a wall cloth material having permeability to chemical substances is provided on a gypsum board having an adsorption amount of a chemical substance equal to or greater than the standard adsorption amount. The first simulated wall material 23 may be configured so that the amount of chemical substances adsorbed is equal to or greater than the reference amount, and may be a wall material in which a plaster board that adsorbs less than the reference amount of chemical substances is used and diatomaceous earth or the like, which has high chemical adsorption properties, is applied to the plaster board. When the first simulated wall material 23 is inserted into the first wall material support portion 2131, it abuts against the rear end portions of the pair of first simulated wall structures 211a, 211b forward of the rear wall portion 213, but can be removed from the first wall material support portion 2131.

In addition, in the first model body 21, the bottom wall portion 214 is connected to the lower end portion of the pair of first simulated wall structures 211a, 211b, and the first floor material support portion 2141 is provided above the bottom wall portion 214. The first floor material support portion 2141 is a portion of the first model body 21 that detachably supports the first simulated floor material 22. The first simulated floor material 22 is an example of a first emission amount regulation material arranged to face the first simulated indoor space S1. The first simulated floor material 22 is a plate-shaped floor material made of a building material whose emission amount of chemical substances is equal to or less than a predetermined standard emission amount. When the first simulated floor material 22 is inserted into the first floor material support portion 2141, it abuts against the lower end portion of the pair of first simulated wall structures 211a, 211b above the bottom wall portion 214, but can be removed from the first floor material support portion 2141.

In the first building model 2, with the first simulated wall material 23 inserted into the first wall material support portion 2131 and the first simulated floor material 22 inserted into the first floor material support portion 2141, a first simulated indoor space S1 is defined by a pair of first simulated wall structures 211a, 211b, the front wall portion 212, the top wall portion 215, the first simulated floor material 22, and the first simulated wall material 23. In this first simulated indoor space S1, a material visualization body 4 is placed, and first simulated furniture 24 is installed. The first simulated furniture 24 is an imitation of furniture that would be installed in the indoor space of a building.

As described above, in the first building model 2, the first simulated floor material 22 is detachable (insertable) from the first floor material support part 2141, and the first simulated wall material 23 is detachable (insertable) from the first wall material support part 2131. For example, if the concentration of chemical substances in the first simulated indoor space S1 changes due to changes over time, the first simulated floor material 22 and the first simulated wall material 23 can be replaced by attaching and detaching them to and from the respective support parts 2131, 2141.

In the first building model 2, the first simulated wall structure 211a of the pair of first simulated wall structures 211a, 211b has an internal space capable of accommodating a substance visualization body 4 at its lower end portion, and has a first substance outlet 216 that opens the internal space, and a first lid 2161 that opens and closes the first substance outlet 216. The first simulated wall structure 211a allows the substance visualization body 4 to be discharged from the inside of the first simulated wall structure 211a into the first simulated indoor space S1 by opening the first substance outlet 216 with the first lid 2161. On the other hand, the first substance outlet 216 is closed by the first lid 2161, thereby restricting the discharge of the substance visualization body 4 from the inside of the first simulated wall structure 211a into the first simulated indoor space S1.

In addition, in the first building model 2, a fitting 2171 extending in the vertical direction is provided at the rear end portion of the other first simulated wall structure 211b of the pair of first simulated wall structures 211a, 211b. An exhaust port 217 that allows air to be discharged from inside the first simulated indoor space S1 to the outside is formed at the lower end portion of the fitting 2171. This exhaust port 217 is opened and closed by an exhaust opening and closing part 2172 attached to the fitting 2171. When the exhaust port 217 is opened by the exhaust opening and closing part 2172, the air in the first simulated indoor space S1 is discharged to the outside. On the other hand, when the exhaust port 217 is closed by the exhaust opening and closing part 2172, the discharge of air in the first simulated indoor space S1 to the outside is restricted.

As shown in Figures 2 and 3, the first building model 2 further includes a first ventilation mechanism 25 and a first ventilation visualization unit 26.

The first ventilation mechanism 25 has an intake fan 251 and a first exhaust fan 252, and ventilates the first simulated indoor space S1 by operating the intake fan 251 and the first exhaust fan 252. The intake fan 251 is provided at an intake port formed at the front upper end portion of one of the pair of first simulated wall structures 211a and 211b, the first simulated wall structure 211a. The intake fan 251 is a fan for supplying outside air into the first simulated indoor space S1. The first exhaust fan 252 is installed in an exhaust path portion 2521 provided outside the other of the pair of first simulated wall structures 211a and 211b. The exhaust path portion 2521 is a path that communicates with the exhaust port 217, and forms an exhaust path through which air exhausted from the exhaust port 217 flows. The first exhaust fan 252 is a fan for discharging air from the first simulated indoor space S1 through the exhaust port 217.

The first ventilation mechanism 25 ventilates the first simulated indoor space S1 by generating a first ventilation flow 250 in the first simulated indoor space S1 that flows from near the front upper end of the first simulated wall structure 211a, on which the supply fan 251 is provided, toward the exhaust port 217, based on the ventilation operation in response to the operation of the supply fan 251 and the first exhaust fan 252.

The first ventilation visualization unit 26 is attached to the fitting 2171 so as to be located near the exhaust port 217. The first ventilation visualization unit 26 visualizes the strength (ventilation volume) of the first ventilation flow 250 generated in the first simulated indoor space S1 by the ventilation operation of the first ventilation mechanism 25. The first ventilation visualization unit 26 is, for example, a windmill rotated by the first ventilation flow 250. When the first ventilation visualization unit 26 is composed of a windmill, the greater the strength of the first ventilation flow 250, the faster it rotates, and this rotation state allows the visitor to recognize the strength of the first ventilation flow 250.

Next, the second building model 3 will be described with reference to Figures 4 and 5. The second building model 3 includes a second model body 31, a second simulated floor material 32, a second simulated wall material 33, and a second simulated furniture 34.

The second model body 31 constitutes the main body of the second building model 3. The second model body 31 is formed in a rectangular box shape by a pair of second simulated wall structures 311a, 311b, a front wall portion 312, a rear wall portion 313, a bottom wall portion 314, and a top wall portion 315. The second model body 31 is configured in the same manner as the first model body 21 of the first building model 2 described above, so a detailed description will be omitted.

In the second model body 31, the rear end portion of the pair of second simulated wall structures 311a, 311b is provided with the second wall material support portion 3131 in front of the rear wall portion 313 with the rear wall portion 313 connected. The second wall material support portion 3131 is a portion of the second model body 31 that detachably supports the second simulated wall material 33. The second simulated wall material 33 is an example of a second adsorption amount regulation material arranged to face the inside of the second simulated indoor space S2. The second simulated wall material 33 is a plate-shaped wall material made of a building material that has an adsorption amount of a chemical substance less than the reference adsorption amount. Specifically, the second simulated wall material 33 is a wall material in which a wall cloth material that does not have chemical substance permeability is provided on a gypsum board that has an adsorption amount of a chemical substance less than the reference adsorption amount. When the second simulated wall material 33 is inserted into the second wall material support portion 3131, it abuts against the rear end portions of the pair of second simulated wall structures 311a, 311b forward of the rear wall portion 313, but can be removed from the second wall material support portion 3131.

In addition, in the second model body 31, the second floor material support part 3141 is provided above the bottom wall part 314 with the bottom wall part 314 connected to the lower end part of the pair of second simulated wall structures 311a, 311b. The second floor material support part 3141 is a part that detachably supports the second simulated floor material 32 in the second model body 31. The second simulated floor material 32 is an example of a second emission amount regulation material arranged to face the inside of the second simulated indoor space S2. The second simulated floor material 32 is a plate-shaped floor material made of a building material whose emission amount of a chemical substance exceeds the standard emission amount. When the second simulated floor material 32 is inserted into the second floor material support part 3141, it abuts against the lower end part of the pair of second simulated wall structures 311a, 311b above the bottom wall part 314, but can be removed from the second floor material support part 3141.

In the second building model 3, with the second simulated wall material 33 inserted into the second wall material support portion 3131 and the second simulated floor material 32 inserted into the second floor material support portion 3141, a second simulated indoor space S2 is defined by a pair of second simulated wall structures 311a, 311b, the front wall portion 312, the top wall portion 315, the second simulated floor material 32, and the second simulated wall material 33. In this second simulated indoor space S2, a material visualization body 4 is placed, and second simulated furniture 34 is installed. The second simulated furniture 34 is an imitation of furniture that would be installed in the indoor space of a building.

As described above, in the second building model 3, the second simulated floor material 32 is detachable (insertable) from the second floor material support part 3141, and the second simulated wall material 33 is detachable (insertable) from the second wall material support part 3131. For example, if the concentration of chemical substances in the second simulated indoor space S2 changes due to changes over time, the second simulated floor material 32 and the second simulated wall material 33 can be replaced by attaching and detaching the second simulated floor material 32 and the second simulated wall material 33 to and from the respective support parts 3131, 3141.

In the second building model 3, the second simulated wall structure 311a of the pair of second simulated wall structures 311a, 311b has an internal space capable of accommodating a substance visualization body 4 at its lower end portion, and has a second substance outlet 316 that opens the internal space, and a second lid 3161 that opens and closes the second substance outlet 316. The second simulated wall structure 311a allows the substance visualization body 4 to be discharged from the inside of the second simulated wall structure 311a into the second simulated indoor space S2 by opening the second substance outlet 316 with the second lid 3161. On the other hand, the second substance outlet 316 is closed by the second lid 3161, so that the discharge of the substance visualization body 4 from the inside of the second simulated wall structure 311a into the second simulated indoor space S2 is restricted.

In the second building model 3, a fitting 3171 extending in the vertical direction is provided at the rear end portion of the other of the pair of second simulated wall structures 311a, 311b, the second simulated wall structure 311b. An exhaust port 317 that allows air to be discharged from the second simulated indoor space S2 to the outside is formed at the lower end portion of the fitting 3171. This exhaust port 317 is opened and closed by an exhaust opening/closing part 3172 attached to the fitting 3171. When the exhaust port 317 is opened by the exhaust opening/closing part 3172, the air in the second simulated indoor space S2 is discharged to the outside. On the other hand, when the exhaust port 317 is closed by the exhaust opening/closing part 3172, the discharge of air in the second simulated indoor space S2 to the outside is restricted.

As shown in Figures 4 and 5, the second building model 3 further includes a second ventilation mechanism 35 and a second ventilation visualization unit 36.

The second ventilation mechanism 35 has a ventilation window 351 and a second exhaust fan 352, and ventilates the second simulated indoor space S2 by operating the second exhaust fan 352 with the ventilation window 351 open. The ventilation window 351 is provided in an intake port formed in the front upper end portion of one of the pair of second simulated wall structures 311a, 311b. The ventilation window 351 is a window for supplying outside air into the second simulated indoor space S2. The second exhaust fan 352 is installed in an exhaust path portion 3521 provided outside the other of the pair of second simulated wall structures 311a, 311b. The exhaust path portion 3521 is a path that communicates with the exhaust port 317, and forms an exhaust path through which air exhausted from the exhaust port 317 flows. The second exhaust fan 352 is a fan for discharging air from the second simulated indoor space S2 through the exhaust port 317.

The second ventilation mechanism 35 ventilates the second simulated indoor space S2 by generating a second ventilation flow 350 in the second simulated indoor space S2 that flows from near the front upper end of the second simulated wall structure 311a, in which the ventilation window 351 is provided, toward the exhaust port 317, based on the ventilation operation in response to the operation of the second exhaust fan 352 with the ventilation window 351 open.

The second ventilation visualization unit 36 is attached to the fitting 3171 so as to be located near the exhaust port 317. The second ventilation visualization unit 36 visualizes the strength (ventilation volume) of the second ventilation flow 350 generated in the second simulated indoor space S2 by the ventilation operation of the second ventilation mechanism 35. The second ventilation visualization unit 36 is, for example, a windmill rotated by the second ventilation flow 350. When the second ventilation visualization unit 36 is composed of a windmill, the greater the strength of the second ventilation flow 350, the faster it rotates, and this rotation state allows the visitor to recognize the strength of the second ventilation flow 350.

As described above, in the exhibition device 1, the first building model 2 and the second building model 3 are made using simulated floor materials 22, 32 with different amounts of chemical substance emission, and simulated wall materials 23, 33 with different amounts of chemical substance adsorption. Therefore, the concentration of chemical substances differs between the first simulated indoor space S1 of the first building model 2 and the second simulated indoor space S2 of the second building model 3.

That is, the first concentration of the chemical substance in the first simulated indoor space S1 of the first building model 2, which includes the first simulated floor material 22 with a low emission amount of the chemical substance and the first simulated wall material 23 with a high adsorption amount of the chemical substance, is lower than the second concentration of the chemical substance in the second simulated indoor space S2 of the second building model 3. As a result, a difference in the odor caused by the chemical substance occurs according to the difference in the concentration of the chemical substance between the first simulated indoor space S1 and the second simulated indoor space S2, so that the visitor can olfactorily recognize that the emission amount and adsorption amount of the chemical substance in the building material used in the construction of the building are related to the concentration of the chemical substance in the indoor space based on the difference in the odor. When the visitor smells the odor caused by the chemical substance in each space of the first simulated indoor space S1 and the second simulated indoor space S2, the first simulated indoor space S1 is opened in response to the rotation of the top wall portion 215 in the first building model 2, and the second simulated indoor space S2 is opened in response to the rotation of the top wall portion 315 in the second building model 3. This allows visitors to easily smell the odors caused by chemicals in each of the first and second simulated indoor spaces S1 and S2.

Moreover, the exhibition device 1 is equipped with a substance visualization body 4 that visualizes and displays chemical substances. The substance visualization body 4 can visualize the difference in concentration of chemical substances between the first simulated indoor space S1 and the second simulated indoor space S2 by the number of substance visualization bodies 4 arranged in each space. In other words, since the first simulated indoor space S1 has a lower concentration of chemical substances than the second simulated indoor space S2, in this case, the number of substance visualization bodies 4 arranged in the first simulated indoor space S1 is made smaller than the number of substance visualization bodies 4 arranged in the second simulated indoor space S2. Based on such a difference in the number of substance visualization bodies 4 arranged between the first simulated indoor space S1 and the second simulated indoor space S2, it is possible to visually recognize to visitors that the amount of chemical substances emitted and adsorbed in the building materials used in the construction of a building is related to the concentration of chemical substances in the indoor space.

As described above, by using the exhibition device 1, it is possible for visitors to the exhibition device 1 to recognize the mechanism for reducing the concentration of chemical substances in the indoor space of a building not only olfactory but also visually.

Comparing the first ventilation mechanism 25 of the first building model 2 with the second ventilation mechanism 35 of the second building model 3, the first ventilation mechanism 25 has a supply fan 251 as a mechanism for supplying outside air to each of the simulated indoor spaces S1 and S2, whereas the second ventilation mechanism 35 has a ventilation window 351. Due to this difference in the outside air supply mechanism, the strength of the first ventilation flow 250 generated in the first simulated indoor space S1 by the first ventilation mechanism 25 is greater than the strength of the second ventilation flow 350 generated in the second simulated indoor space S2 by the second ventilation mechanism 35. In other words, the ventilation volume of the first ventilation mechanism 25 is greater than the ventilation volume of the second ventilation mechanism 35.

The difference in the strength of the ventilation flow between the first ventilation flow 250 in the first simulated indoor space S1 and the second ventilation flow 350 in the second simulated indoor space S2 is visualized by the first ventilation visualization unit 26 and the second ventilation visualization unit 36. This allows the visitor to visually recognize that the difference in the ventilation structure between the first ventilation mechanism 25 and the second ventilation mechanism 35 is related to the strength of the ventilation flow, and also allows the visitor to recognize that the strength of the ventilation flow is related to the concentration of chemical substances in the indoor space.

The material visualization bodies 4 arranged in the first simulated indoor space S1 and the second simulated indoor space S2 are spheres made of a porous and low-mass material such as polystyrene foam. The material visualization bodies 4 are configured to be movable in response to ventilation by at least the first ventilation mechanism 25 of the first ventilation mechanism 25 and the second ventilation mechanism 35. That is, the material visualization body 4 arranged in the first simulated indoor space S1 is moved along the upper surface of the first simulated floor material 22 by the first ventilation flow 250 generated in the first simulated indoor space S1 in response to ventilation by the first ventilation mechanism 25. The upper surface of the first simulated floor material 22 is an example of the floor surface in the first model body 21. On the other hand, the material visualization body 4 arranged in the second simulated indoor space S2 is moved along the upper surface of the second simulated floor material 32 by the second ventilation flow 350 generated in the second simulated indoor space S2 in response to ventilation by the second ventilation mechanism 35, or is not moved by the second ventilation flow 350.

In this embodiment, the substance visualization body 4 is configured to be movable by the first ventilation flow 250 and also by the second ventilation flow 350. Even if the substance visualization body 4 is movable by the second ventilation flow 350, the strength of the first ventilation flow 250 is greater than the strength of the second ventilation flow 350, so the movement speed of the substance visualization body 4 in the first simulated indoor space S1 is faster than the movement speed of the substance visualization body 4 in the second simulated indoor space S2. Since it is possible to visually recognize such a difference in the movement speed of the substance visualization body 4, it is possible to visually recognize that a difference occurs in the emission speed of chemical substances from the indoor space depending on the difference in the ventilation structure between the first ventilation mechanism 25 and the second ventilation mechanism 35.

The substance visualization body 4 also includes multiple types of visualization bodies having different characteristics for multiple types of sources of chemical substances provided in the first simulated indoor space S1 and the second simulated indoor space S2. Specifically, the substance visualization body 4 includes a building material-derived substance body 41, a wall-derived substance body 42, and a furniture-derived substance body 43. The building material-derived substance body 41 is assumed to be a chemical substance whose source is the building materials constituting the first simulated floor material 22 and the second simulated floor material 32. The wall-derived substance body 42 is assumed to be a chemical substance whose source is the first simulated wall structures 211a, 211b and the second simulated wall structures 311a, 311b. In the first building model 2, the wall-derived substance 42 is discharged from the inside of the first simulated wall structure 211a into the first simulated indoor space S1 with the first lid 2161 opening the first substance outlet 216, and in the second building model 3, the wall-derived substance 42 is discharged from the inside of the second simulated wall structure 311a into the second simulated indoor space S2 with the second lid 3161 opening the second substance outlet 316. The furniture-derived substance 43 is assumed to be a chemical substance generated from the first simulated furniture 24 and the second simulated furniture 34.

The building material-derived substance body 41, the wall-derived substance body 42, and the furniture-derived substance body 43 may each be colored in a different color. Because the building material-derived substance body 41, the wall-derived substance body 42, and the furniture-derived substance body 43 are visualized, the visitor can visually recognize that chemical substances are emitted from the floor materials and wall structures that make up the building, and can also recognize that chemical substances are emitted from furniture installed in the indoor space.

In this embodiment, before the first ventilation mechanism 25 and the second ventilation mechanism 35 are operated, the substance visualization bodies 4 are arranged at predetermined positions in the first simulated indoor space S1 of the first building model 2 and the second simulated indoor space S2 of the second building model 3 in a number corresponding to the concentration difference of the chemical substance between the first simulated indoor space S1 and the second simulated indoor space S2. Specifically, the building material-derived substance body 41 is arranged on the first simulated floor material 22 in the first simulated indoor space S1 and on the second simulated floor material 32 in the second simulated indoor space S2. The wall-derived substance body 42 is arranged inside one of the pair of first simulated wall structures 211a, 211b, the first simulated wall structure 211a, and inside one of the pair of second simulated wall structures 311a, 311b, the second simulated wall structure 311a. The furniture-derived material body 43 is placed on the first simulated furniture 24 in the first simulated indoor space S1, and is placed on the second simulated furniture 34 in the second simulated indoor space S2.

When the placement of the building material-derived substance body 41, wall-derived substance body 42, and furniture-derived substance body 43 constituting the substance visualization body 4 in the prescribed positions is completed, the first ventilation mechanism 25 and the second ventilation mechanism 35 are operated. In this way, by changing the type of substance visualization body 4 for each chemical substance source provided in the first simulated indoor space S1 and the second simulated indoor space S2 and placing them in prescribed positions in each simulated indoor space S1, S2, and then operating the first ventilation mechanism 25 and the second ventilation mechanism 35, visitors can visually recognize the process from the generation to the emission of chemical substances.

The building material-derived material body 41, the wall-derived material body 42, and the furniture-derived material body 43 are all different in size. For example, the building material-derived material body 41 is the largest, the furniture-derived material body 43 is the smallest, and the wall-derived material body 42 is between the building material-derived material body 41 and the furniture-derived material body 43 in size. In the exhibition device 1, the first building model 2 includes the first collection section 27, and the second building model 3 includes the second collection section 37.

In the first building model 2, the first collection section 27 separates and collects the material visualization bodies 4 that move along the upper surface of the first simulated floor material 22 in the first simulated indoor space S1 by the first ventilation flow 250 and are discharged from the exhaust port 217 into building material-derived material bodies 41, wall-derived material bodies 42, and furniture-derived material bodies 43. In the first model body 21, the exhaust port 217 is provided at a position that can receive the material visualization bodies 4 that move along the upper surface of the first simulated floor material 22. The first collection section 27 is disposed outside the first simulated indoor space S1 at a position lower than the upper surface of the first simulated floor material 22. The first collection section 27 has a first collection housing 271, a first upper collection section 272, a first middle collection section 273, and a first lower collection section 274. That is, the first collection section 27 has a multi-layer structure in which multiple collection sections 272, 273, and 274 are stacked on top of each other so that the building material-derived material 41, the wall-derived material 42, and the furniture-derived material 43 can be collected according to size.

The first collection housing 271 is a housing arranged below the exhaust path 2521 through which air discharged from the first simulated indoor space S1 through the exhaust port 217 flows and below the first simulated floor material 22. The first collection housing 271 receives the substance visualization body 4 guided from the exhaust port 217 to the exhaust path 2521 by the first ventilation flow 250. In the first collection housing 271, the first upper collection section 272, the first middle collection section 273, and the first lower collection section 274 are arranged stacked in the vertical direction. In the first collection housing 271, the first upper collection section 272 is arranged at the top, the first lower collection section 274 is arranged at the bottom, and the first middle collection section 273 is arranged between the first upper collection section 272 and the first lower collection section 274.

The first upper recovery section 272 has an upper hole 2721 with a hole diameter that prevents the passage of the building material-derived substance 41, while allowing the wall-derived substance 42 and furniture-derived substance 43 to pass through. As a result, of the substance visualization objects 4 received by the first recovery housing 271, the wall-derived substance 42 and furniture-derived substance 43 pass through the upper hole 2721 and are introduced into the first middle recovery section 273, while the building material-derived substance 41 is recovered in the first upper recovery section 272.

The first middle recovery section 273 has a middle hole 2731 with a hole diameter that prevents the passage of the wall-derived material 42 and allows the passage of the furniture-derived material 43. As a result, of the wall-derived material 42 and the furniture-derived material 43 introduced into the first middle recovery section 273, the furniture-derived material 43 passes through the middle hole 2731 and is introduced into the first lower recovery section 274, while the wall-derived material 42 is recovered in the first middle recovery section 273.

Comparing the upper stage hole 2721 of the first upper stage recovery section 272 and the middle stage hole 2731 of the first middle stage recovery section 273, the hole diameter of the upper stage hole 2721 of the first upper stage recovery section 272, which is located at the top, is larger than the hole diameter of the middle stage hole 2731 of the first middle stage recovery section 273.

The first lower recovery section 274 recovers furniture-derived material 43 introduced through the middle hole 2731. The first lower recovery section 274, which is the lowest section, does not have any holes.

On the other hand, in the second building model 3, the second collection section 37 separates and collects the material visualization bodies 4 that move along the upper surface of the second simulated floor material 32 in the second simulated indoor space S2 by the second ventilation flow 350 and are discharged from the exhaust port 317 into building material-derived material bodies 41, wall-derived material bodies 42, and furniture-derived material bodies 43. Note that the exhaust port 317 in the second model body 31 is provided at a position that can receive the material visualization bodies 4 that move along the upper surface of the second simulated floor material 32. The second collection section 37 is disposed outside the second simulated indoor space S2 at a position lower than the upper surface of the second simulated floor material 32.

The second collection section 37 has a second collection housing 371, a second upper collection section 372, a second middle collection section 373, and a second lower collection section 374. That is, the second collection section 37 has a multi-layer structure in which multiple collection sections 372, 373, and 374 are stacked so that the building material-derived material bodies 41, the wall-derived material bodies 42, and the furniture-derived material bodies 43 can be collected by size. The multiple collection sections 372, 373, and 374 in the second collection section 37 are configured in the same way as the multiple collection sections 272, 273, and 274 in the first collection section 27 described above, so detailed explanations will be omitted.

In a configuration in which the first building model 2 includes the first collection section 27 and the second building model 3 includes the second collection section 37, the substance visualization bodies 4 moving within the first simulated indoor space S1 by the first ventilation flow 250 and the substance visualization bodies 4 moving within the second simulated indoor space S2 by the second ventilation flow 350 can be separated and collected into building material-derived substance bodies 41, wall-derived substance bodies 42, and furniture-derived substance bodies 43 using the first collection section 27 and the second collection section 37. This allows the substance visualization bodies 4 to be efficiently returned to their designated positions after moving within the first simulated indoor space S1 and the second simulated indoor space S2.

If the substance visualization body 4 is configured to be movable by the first ventilation flow 250 but not by the second ventilation flow 350, the installation of the second collection section 37 may be omitted.

Next, we will explain the procedure for explaining to visitors the mechanism for reducing the concentration of chemical substances in the indoor space of a building using the exhibition device 1.

First, substance visualization bodies 4 are placed at predetermined positions in the first simulated indoor space S1 of the first building model 2 and the second simulated indoor space S2 of the second building model 3, with the number of substance visualization bodies 4 corresponding to the difference in concentration of chemical substances between the first simulated indoor space S1 and the second simulated indoor space S2. At this time, since the first simulated indoor space S1 has a lower concentration of chemical substances than the second simulated indoor space S2, the number of substance visualization bodies 4 placed in the first simulated indoor space S1 is made smaller than the number of substance visualization bodies 4 placed in the second simulated indoor space S2. The building material-derived substance bodies 41 are placed on the first simulated floor material 22 in the first simulated indoor space S1, and on the second simulated floor material 32 in the second simulated indoor space S2. The wall-derived material 42 is disposed inside one of the pair of first simulated wall structures 211a, 211b, the first simulated wall structure 211a, and inside one of the pair of second simulated wall structures 311a, 311b, the second simulated wall structure 311a. The furniture-derived material 43 is disposed on the first simulated furniture 24 in the first simulated indoor space S1, and on the second simulated furniture 34 in the second simulated indoor space S2.

Once the placement of the substance visualization bodies 4 is complete, an explanation is given to the visitors using the exhibition device 1. At this time, it is explained to the visitors that the first concentration of the chemical substance in the first simulated indoor space S1 of the first building model 2, which includes the first simulated floor material 22 with a low amount of chemical substance emission and the first simulated wall material 23 with a high amount of chemical substance adsorption, is lower than the second concentration of the chemical substance in the second simulated indoor space S2 of the second building model 3. Then, based on the difference in the number of substance visualization bodies 4 placed between the first simulated indoor space S1 and the second simulated indoor space S2, the visitors are visually made to recognize that the amounts of chemical substance emission and adsorption in the building materials used in the construction of the building are related to the concentrations of chemical substances in the indoor spaces.

Next, in the first building model 2, the first substance outlet 216 is opened by the first lid 2161. As a result, the wall-derived substance 42 disposed inside the first simulated wall structure 211a is discharged into the first simulated indoor space S1 through the first substance outlet 216. Meanwhile, in the second building model 3, the second lid 3161 is opened by the second substance outlet 316. As a result, the wall-derived substance 42 disposed inside the second simulated wall structure 311a is discharged into the second simulated indoor space S2 through the second substance outlet 316. This discharge of the wall-derived substance 42 into the first simulated indoor space S1 and the second simulated indoor space S2 allows visitors to recognize that chemical substances are dissipated from inside the wall structures in an actual building.

Next, in the first building model 2, the supply air fan 251 and the first exhaust fan 252 of the first ventilation mechanism 25 are operated with the exhaust port 217 open by the exhaust opening/closing part 2172. This generates a first ventilation flow 250 flowing from near the front upper end of the first simulated wall structure 211a, where the supply air fan 251 is provided, toward the exhaust port 217 in the first simulated indoor space S1, and the first ventilation flow 250 ventilates the first simulated indoor space S1. Meanwhile, in the second building model 3, the exhaust port 317 is opened by the exhaust opening/closing part 3172, and the ventilation window 351 of the second ventilation mechanism 35 is opened to operate the second exhaust fan 352. As a result, a second ventilation flow 350 is generated in the second simulated indoor space S2, flowing from near the front upper end of the second simulated wall structure 311a, where the ventilation window 351 is provided, toward the exhaust port 317, and the second ventilation flow 350 ventilates the second simulated indoor space S2.

The difference in the strength of the ventilation flow between the first ventilation flow 250 in the first simulated indoor space S1 and the second ventilation flow 350 in the second simulated indoor space S2 is visualized by the first ventilation visualization unit 26 and the second ventilation visualization unit 36. This allows the visitor to visually recognize that the difference in the ventilation structure between the first ventilation mechanism 25 and the second ventilation mechanism 35 is related to the strength of the ventilation flow, and also allows the visitor to recognize that the strength of the ventilation flow is related to the concentration of chemical substances in the indoor space.

The substance visualization object 4 arranged in the first simulated indoor space S1 is moved by the first ventilation flow 250, while the substance visualization object 4 arranged in the second simulated indoor space S2 is moved by the second ventilation flow 350. At this time, since the strength of the first ventilation flow 250 is greater than the strength of the second ventilation flow 350, the movement speed of the substance visualization object 4 in the first simulated indoor space S1 is faster than the movement speed of the substance visualization object 4 in the second simulated indoor space S2. Since it is possible to visually allow the visitor to recognize such a difference in the movement speed of the substance visualization object 4, it is possible to visually allow the visitor to recognize that a difference occurs in the emission speed of chemical substances from the indoor space depending on the difference in the ventilation structure between the first ventilation mechanism 25 and the second ventilation mechanism 35.

The substance visualization bodies 4 moving in the first simulated indoor space S1 by the first ventilation flow 250 are led from the exhaust port 217 to the exhaust path section 2521, and are separated into building material-derived substance bodies 41, wall-derived substance bodies 42, and furniture-derived substance bodies 43, and are collected in the first collection section 27. On the other hand, the substance visualization bodies 4 moving in the second simulated indoor space S2 by the second ventilation flow 350 are led from the exhaust port 317 to the exhaust path section 3521, and are separated into building material-derived substance bodies 41, wall-derived substance bodies 42, and furniture-derived substance bodies 43, and are collected in the second collection section 37.

Next, in the first building model 2, the first simulated indoor space S1 is opened in response to the rotation of the top wall portion 215, and in the second building model 3, the second simulated indoor space S2 is opened in response to the rotation of the top wall portion 315. This allows the visitor to easily smell the odors caused by chemical substances in each space of the first simulated indoor space S1 and the second simulated indoor space S2. At this time, a difference in the odor caused by chemical substances occurs according to the difference in concentration of chemical substances between the first simulated indoor space S1 and the second simulated indoor space S2, so that the visitor can olfactory recognize that the amount of chemical substances emitted and adsorbed in the building materials used in the construction of the building is related to the concentration of chemical substances in the indoor space based on the difference in odor.

As described above, by using the exhibition device 1, it is possible for visitors to the exhibition device 1 to recognize the mechanism for reducing the concentration of chemical substances in the indoor space of a building not only olfactory but also visually.

When the explanation to the visitors about the mechanism of reducing the concentration of chemical substances is finished, the substance visualization objects 4 collected in the first collection section 27 are returned to their designated positions in the first building model 2. Similarly, the substance visualization objects 4 collected in the second collection section 37 are returned to their designated positions in the second building model 3. At this time, since the substance visualization objects 4 are collected in the first collection section 27 and the second collection section 37 by dividing them into building material-derived substance objects 41, wall-derived substance objects 42, and furniture-derived substance objects 43, the substance visualization objects 4 can be returned to their designated positions efficiently.

In addition, for example, if the concentration of chemical substances in the first simulated indoor space S1 changes due to changes over time, the first simulated floor material 22 and the first simulated wall material 23 can be replaced by attaching and detaching the first simulated floor material 22 and the first simulated wall material 23 to and from the respective supports 2131, 2141. Similarly, if the concentration of chemical substances in the second simulated indoor space S2 changes due to changes over time, the second simulated floor material 32 and the second simulated wall material 33 can be replaced by attaching and detaching the second simulated floor material 32 and the second simulated wall material 33 to and from the respective supports 3131, 3141.
