Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a space within a building where human life activities take place.
This invention relates to a device that improves the living environment of humans by introducing vitality generated by trees, as seen in forests, and creates a place where people can live better both physically and mentally.

(Conventional technology and its issues) In recent years, human life has become concentrated in cities due to the development of science, technology, and industry, and the human living environment, especially the atmospheric environment, is deteriorating.

In the past, the biologically active functions of forest trees purified the atmosphere by adsorbing harmful gases and replenishing oxygen, creating an environment suitable for sustaining our lives and supporting our daily activities.

In other words, forest trees absorb fine dust, Nox, contained in the air.
At the same time, it absorbs and removes harmful substances such as Sox, and at the same time supplies fresh oxygen. It also absorbs hydrocarbons such as monoterpenes and sesquiterpenes, or those with hydroxyl groups, aldehyde groups, etc. bonded to them, diterpenes, It is known that volatile organic compounds (phytoncides) such as phenolic compounds are released, and these physiologically active plant substances have effects on human mental sedation, stability, alertness, blood pressure, muscle strength, breathing, gastrointestinal digestion, Physiological activities in human life such as diuresis, sterilization, insecticidal, etc.
It is said that it contributes to the creation of the environment.

However, due to recent urbanization, the density of tree vegetation within the human living environment in cities is decreasing year by year, making it difficult to regenerate against environmental damage such as air pollution caused by human life, and the living environment continues to deteriorate. The current situation is that we are moving forward.

BACKGROUND ART Conventionally, as a means to improve the deterioration of urban air quality, indoor air has been passed through a filter to remove suspended matter, or passed through a filter material such as activated carbon to remove odors and the like.

Although this technology has certain effects, it only removes harmful substances and does not provide components that contribute to human physiological activities, like forest trees do.

Recently, fragrances or essential oils extracted from trees have been used to diffuse indoor air using air conditioners to improve the indoor air environment, but these are some of the components emitted by trees. It is just a part-time activity, and you cannot expect the same effects as forest bathing.

Furthermore, potted plants are placed in houses, offices, etc., but the purpose of this is to improve the visual environment and to obtain emitted components to the extent that they contribute to human physiological activity. I can't do that.

For these reasons, there is a desire to make human living spaces in buildings similar to forest environments, and there is a strong demand for the development of artificial forest technology that can generate a large amount of radiated components in a small space.

(Means for achieving the objective) In order to achieve the above objective, plants are planted in a predetermined space and the volatile organic compounds emitted by the plants are supplied to the buildings where human life is carried out. In an air purifying device that purifies the air by means of a method, a stimulation device is provided which applies mechanical stimulation to branches and leaves in order to increase the amount of volatile organic compounds generated.

The stimulation device may be a water injection device that intermittently injects water toward the branches or leaves, or a vibration imparting device that vibrates a vibrator in contact with the branches or leaves, and the vibrator may be a rod-shaped body. It is a helical spring or a rotating device equipped with a contact that contacts the branches and leaves.

In addition, some plants are equipped with a stimulation device that applies stimulation to branches and leaves without contact.

An example of this stimulation device uses air vibration.
These air vibrations include ultra-low frequency vibrations and ultrasonic vibrations.

Other examples include devices that utilize electric vibrations, such as dielectric vibration devices that generate dielectric vibrations within plants, and induction vibration devices that generate induced vibrations in plants.

Still another example is a lighting device with variable irradiation light that changes the physiological phenomena caused by light in plants.

(Effect) As mentioned above, when many trees are cultivated in a small space, the physiological activity of the trees is activated by applying various stimuli to the branches and leaves, and the air purification effect is similar to that of a large natural forest. By supplying this atmosphere to human living spaces, it is possible to increase human physiological activity and achieve mental stability in city life, just as in forests.

(Example) Before explaining each specific example, general examples are shown in FIGS. 1 and 2.

FIG. 1 shows a rooftop installation type, in which trees 5.5 are placed on a cultivation bed 4 provided on a head 3 in a plant vegetation space 6 inside a container 1 made of transparent material or the like to isolate it from the outside world 7. ... have been planted to form an artificial forest. One side of this container 1 is provided with an outside air intake port 1'', and the other side is provided with a duct 9 so that the outside air that has passed through the artificial forest is introduced into the human living space 10 of the building 2 by a blower 8. It is connected.

Figure 2 shows an underground installation type, with a lighting device 90 inside the container.
The rest is the same, except that a duct 9 for sucking outside air with a suction blower 8 is connected to the outside air intake port 1''.

Next, the internal tank bottom of the above container 1 will be explained for each example.

Example 1 FIG. 3 is an explanatory diagram of this example. In this figure, the container l for defining a predetermined space from the outside world is omitted. (The same applies to each example below) Trees 5.
5,... are planted more densely than in a natural forest, and a water pipe 12 with nozzles 1k 11... directed toward these trees 5.5,... passes through a container 1 (not shown). It is provided. A pump 13 is connected to this water pipe 12 for feeding water from a water tank 14 to the outside of the container 1. Furthermore, this pump 13 has a control device 1 for intermittently feeding water.
5.

Next, the operation of this device will be explained.

Water is intermittently sprayed from a nozzle 11 toward a tree 5 whose size and number of branches and leaves have been increased by thinning or a straightening agent, etc., and mechanical stimulation is applied to the branches and leaves of the tree 5, thereby reducing the plant's retention. It stimulates the volatile organic compound generating function of the body and increases the amount generated.

As a result, even plants grown in a small space can generate a large amount of volatile organic compounds.

Embodiment 2 FIG. 4 is an explanatory diagram of this embodiment. Adjacent trees 5
．． A connecting rod 2 in which a rod-shaped vibrator 21 is provided horizontally on the cultivation bed 4 so as to contact the branches and leaves of these trees 5 between
2 is fixed vertically. One end of the connecting rod 22 is connected to a vibrator 23 that vibrates in the axial direction of the connecting rod 22, and the other end is held by a holder 24 so as to be movable in the axial direction.

The rod-shaped vibrator 21 may be a single rod-shaped vibrator, or may be provided with horizontal bars as appropriate, or may have hanging objects suspended from the horizontal bars to increase the number of contact areas with branches and leaves.

Next, the operation of this device will be explained.

The planting state of the tree 5 is the same as in Example 1, but the vibrator 2
3 causes the connecting rod 22 to vibrate longitudinally in the axial direction.

This vibration causes the rod-shaped vibrator 2I to generate transverse vibration, which mechanically stimulates the branches and leaves in contact with the rod-shaped vibrator 2I, thereby promoting the generation of volatile organic compounds.

Fruit can 1 chestnut 3 In this embodiment, as shown in FIG. 5, a helical spring 31 is used in place of the rod-shaped vibrator 21 in the case of the above-mentioned embodiment 2, and other aspects are the same as in the embodiment 2. Therefore, detailed explanation will be omitted.

Note that the helical spring 31 is not limited to this shape, and may have any shape.

Example 4 This example is of a rotating type. As shown in FIG. 6, adjacent trees 5 are rotated by a rotating machine 41 provided on the cultivation bed 4, and a rotating device 44 consisting of a rotating shaft 43 with a plurality of contacts 42 projecting laterally is attached to the rotating device 44. .5.

Note that the contactor 42 may be provided with a suspension body at its tip to increase the contact portion with branches and leaves.

Next, the operation of this device will be explained.

Since the contacts 42 rotated by each rotary machine 41 rotate horizontally so as to pass through the branches and leaves, the contacted branches and leaves receive mechanical stimulation and promote the generation of volatile organic compounds.

Each of the above embodiments is of a contact type, but each of the following embodiments is of a non-contact type.

Embodiment 5 FIG. 7 is an explanatory diagram of this embodiment. This embodiment utilizes air vibration. A vibration converter 51 is provided on the upper side (the side surface or the lower side may be sufficient) of each tree 5, and these vibration converters 51 convert electric vibrations into air vibrations using an oscillating current generator 52.

In this case, there are two types of vibration frequency: ultra-low frequency that cannot be heard by human ears, and vibration frequency that uses ultrasonic waves.

Furthermore, there are two types of oscillating current generator 52: one that outputs continuously and the other that outputs intermittently.

Next, the operation of this embodiment will be explained.

The electric vibration generated by the vibration current generator 52 is transmitted to the vibration converter 5.
1 is converted into air vibration, which causes branches and leaves to vibrate, and this stimulation promotes the generation of volatile organic compounds.

In this case, air vibrations use infrasound or ultrasonic waves, so they are inaudible to the human ear and do not cause any unpleasant sensations.

Embodiment 6 FIG. 8 is an explanatory diagram of this embodiment. This embodiment utilizes electric vibration. Electrodes 61.6I,... are provided between each tree 5.5,..., and these electrodes 61.61
, . . . are connected in parallel every other time to form two groups of electrodes facing each other, and the electrodes of each group are connected to a high frequency power source 62 to form a dielectric excitation device 63.

Next, the operation of this device will be explained.

When a high frequency voltage is applied to each electrode group by the high frequency power supply 62, the branches and leaves generate heat and vibrate in synchronization with the power supply frequency due to dielectric action. As a result, the thermal and mechanical stimulation of vibration promotes the generation of volatile organic compounds.

In this case, it should be noted that if the applied power is too large, the branches and leaves will reach an abnormally high temperature and die, so only a low power can be used.

Furthermore, if the frequency is too high, the vibration of the branches and leaves will not be able to follow the electrical vibration and mechanical vibrations will not be applied, so the lowest possible frequency is required.

Embodiment 7 FIG. 9 is an explanatory diagram of this embodiment. In this example, coils 71 are provided on the upper side (lateral or lower side) of each tree 5, and these coils 71 are connected to high frequency type 'tA7.
2 are connected in parallel to constitute an induced vibration device 73.

Note that when the output impedance of the high frequency power source 72 is high, the coils 71 may be connected in series or connected in series and parallel.

Next, the operation of this device will be explained.

When each coil 71 is excited by the high frequency power source 72, the branches and leaves vibrate in synchronization with the power source frequency due to the generated magnetic lines of force, and as a result, the generation of volatile organic compounds is promoted.

In this case as well, if the power supply frequency is too high, the vibrations of the branches and leaves will not follow and no vibration phenomenon will occur, so it is necessary to set the frequency to the lowest possible.

Embodiment 8 FIG. 10 is an explanatory diagram of this embodiment. This embodiment utilizes stimulation by light. Each tree 5.5,...
A light emitter 81 is provided above (or on the side or below), and this light emitter 81 is connected to a variable power source 82 to constitute a variable illumination device 83.

Note that this light emitter 81 also includes the case of generating far infrared rays.

Next, the operation of this device will be explained.

The light emitter 81 is lit by a variable power source 82;
The brightness changes in synchronization with the change in 2. This brightness may simply change in brightness or may completely flicker. Furthermore, even in the case of complete blinking, there are cases of simple blinking and repeated flashing.

In either case, the foliage is stimulated to generate volatile organic compounds due to stimulation by changes in light.

(Effects of the Invention) As described above, the present invention can perform an air purification effect similar to that of a natural forest in urban buildings, and can also purify a large amount of volatile organic matter in an extremely small space. Since it allows compounds to be generated, it is possible to install it within the narrow human living space.

Therefore, office buildings, which are used as places for daily social activities,
It can be used in all kinds of living spaces, including hospitals and schools, as well as apartments and WA residences, providing mental stability to people living there and preventing symptoms from occurring in patients with allergies such as asthma. You can get the effect of
