Description

[Detailed description of the invention] (Industrial application field) This invention purifies the air indoors of buildings where human life activities are carried out, and supplies a mixture of volatile organic compounds (so-called phytoncides) generated by living plants. The present invention relates to a device that aims to improve the environment for the physiological and mental stability of the human body.

(Prior Art and its Problems) Conventionally, air purification devices that purify indoor air generally remove suspended matter using a filter, and gases such as odors are removed by adsorption using activated carbon or other special filters. Although this technology is effective to some extent, it is strictly within the scope of the idea of removing harmful substances.

Therefore, the effect of resting after feeling tired from working indoors, etc. was not taken into account, and the only way to get rest was to find another way.

However, the air that governs the life activities of living things must not only contain inorganic elements, but also organic elements created by nature.

However, the current air quality in urban spaces tends to increase the amount of harmful substances such as fine dust, sulfur oxides, and nitrogen oxides, and as a result, the need for urban greening and forest bathing has been emphasized. There is.

In short, the tendency to isolate ourselves from nature means that no matter how much emphasis is placed on the need for urban greening, it is difficult to expect natural purification to match the amount of various gases emitted by urban structures.

For this reason, the present applicant has proposed an indoor air purification device using volatile organic compounds that generate living plants in the limited living space of each building using artificial trees.

However, since it is difficult to convert this artificial forest into a large-scale natural forest, the amount of volatile organic compounds generated may be insufficient in the case of large-scale buildings.

An object of the present invention is to solve the above-mentioned problems and to provide a device for accelerating the generation of volatile organic compounds for an air purification device, which can suppress the fatigue caused by working in a large-scale room.

(Means for achieving the object) In order to achieve the above-mentioned object, a volatile organic compound produced by a living plant is used in an air purification device that purifies the air in the indoor space of the building 1 where human daily activities take place. The generator includes a container 2 containing an artificial tree 5' that has been cultured so as to be able to grow the living plants, and a growth promoter provided in the container 2 that mechanically stimulates the branches and leaves of the artificial tree 5'. It consists of a device.

The generation promoting device includes a vibrating device 7 provided in a certain part of the container 2, and a plurality of rope-shaped ropes lowered from the vibrating device 7 so as to come into contact with the branches and leaves.
A rod-shaped or solid brush-shaped suspension body 8 is provided,
A suspension-type development promoting device 11 that vibrates the suspension body 8 to mechanically stimulate the branches and leaves;
The generation promoting device includes a motor 10 provided on the ceiling of the container 2, a rotating device 13 comprising a rotating disk 9 driven by the motor 10, and a rotating device 13 comprising a rotating disk 9 so as to contact the branches and leaves. The rotary development promoting device 12 consists of a plurality of suspended rope-shaped, rod-shaped, or solid brush-shaped suspended bodies 8, and applies mechanical stimulation to the branches and leaves by rotating this rotating device 13. There is.

(Function) As mentioned above, living plants produce different assimilate substances depending on their characteristics, and produce different materials depending on the amount of accumulated substances. Among these produced substances are substances that are useful for human life. This is called the forest scent because it is released during leaf respiration.

These volatile organic compounds currently detected in forests are terpene-based substances, including approximately 330 types of monoterpenes, approximately 1,000 types of sesquiterpenes, and approximately 650 types of diterpenes.

As a result, it is possible to generate a desired amount of terpene-based volatile organic compounds even if the number of artificial trees is small relative to the space targeted for air purification. These terpene-based substances emit a large amount at a certain temperature (25°C to 35°C). In addition to this, when exposed to external stimuli such as fluids and solids, branches and leaves may receive minute scratches.
Each has the property of releasing a specific substance (phytontide) to heal this wound. The present invention attempts to utilize the characteristics of this plant. This is extremely effective in increasing the conventional generation area by making fine scratches on the stomata that normally emanate from the leaf stomata and trunk bark.

(Example) Fig. 1 shows an example of an air purification device using living plants, in which a container 2 containing an artificial forest 5' in which young trees etc. 5 are densely planted is installed on the roof of a building 1, and air is passed through a duct 4 by a blower 3 to each air purifier. It blows air into room 1''.

FIG. 2 shows another example in which a container 2 is installed indoors and a blower 3 blows outside air into each room 1'' through an air intake duct 4' and an air supply duct 4''. In the case of indoor installation as shown in FIG. 2, the illumination device 6 provides supplementary light necessary for plant growth.

In these cases, the preferred amount of volatile organic compounds is determined based on the total volume of each chamber 1'', but if this amount is large, the number of young trees, etc. 5 in the artificial forest 5' in the container 2 will also be large. In such cases, the required number of young trees, etc. 5 may not be able to be accommodated in the container 2. In this case, in order to increase the amount of volatile organic compounds generated from each young tree, etc. 5, It is necessary to devise means to promote the occurrence of

An example of the above-mentioned generation promoting means is shown in FIG. 3. In this embodiment, a plurality of rope-shaped, rod-shaped, or solid brush-shaped suspension bodies 8, 8 are transmitted from a vibration device 7 provided on the ceiling of the container 2 to an artificial tree 5' housed inside the container 2. , ... are lowered so as to touch the branches and leaves of the artificial forest 5'. The upper end of this suspension body 8 is connected to the vibrating part of the vibrating device 7.

As the suspension bodies 8, 8, ropes made of straw, hemp, or straw, chains made of metal, plastic, etc., or metal rods whose upper portions are connected by a ring-shaped body and are swingable can be used.

Alternatively, the artificial forest may be divided into several blocks and each block may be rotated so that the branches and leaves come into contact with each other.

Next, the operation of this device will be explained.

When the blower 3 blows outside air into each room 1'' through the duct 4 through the branches and leaves of the artificial forest 5' in the container 2, the vibration device 7 moves the suspension body 8 up and down.

In this way, the branches and leaves are forcibly shaken,
In the case of a rod-shaped or solid brush-shaped suspension body 8, it may cause a blow or severe abrasion to the branches and leaves, etc.
Although the artificial tree 5' is partially damaged, since it is a living plant, it promotes the generation of volatile organic compounds to heal the wound, and as a result, even in the artificial tree 5' in the relatively narrow container 2, a large amount of volatile organic compounds are generated. Volatile organic compounds are generated.

FIG. 4 shows another embodiment. In this embodiment, a plurality of rotating disks 9, 9, . …
is lowered so as to touch the branches and leaves of the artificial forest 5'. The rotating disk 9 has a structure in which it is slowly rotated by a motor 10 provided outside the container 2.

Next, the operation of this embodiment will be explained. Since the ventilation relationship in this embodiment is the same as in the previous embodiment, a description of this relationship will be omitted.

The suspended bodies 8 are moved slowly along the circumference together with the rotating disk 9 by the motor 10, and at this time each suspended body 8 comes into contact with the branches and leaves of the artificial tree 5' and provides mechanical stimulation. In this case, the rod-shaped suspension body hits the branches and leaves while colliding with them, and the solid brush-shaped suspension body causes severe scratches on the branches and leaves. As a result, as described above, the artificial forest 5' generates a larger amount of volatile organic compounds than usual.

(Effect of the invention) As mentioned above, since the amount of volatile organic compounds required for the indoor space to be supplied can be generated in a small-scale container 2, it can be used on the rooftop or indoors of a building with a limited installation area. Even if the container 2 is installed, it is possible to make the conventional indoor air composition more similar to forest air.
