Hereinafter, exemplary embodiments of the present invention will be
described more fully with reference to the accompanying drawings, in which the
same reference numerals and signs are used throughout the different drawings to
designate the same or similar components.
FIG. 1 is a perspective view illustrating an information booth for
pedestrians according to the present invention, FIG. 2 is a view illustrating the
internal construction of the information booth for pedestrians according to the
present invention, FIG. 3 is a plan view illustrating an air-cleaning hydroxyl
radical generator according to the present invention, and FIG. 4 is a
cross-sectional view illustrating the air inlet in the information booth for
pedestrians according to the present invention.
The information booth for pedestrians of the present invention, in which
the air-cleaning hydroxyl radical generator is installed, includes a body 100, a
frame 110, air inlets 120, air outlets 130 and a hydroxyl radical generator 200, as
shown in FIGS. 1 to 4.
Referring to FIG. 1, showing the construction of the present invention, the
body 100 has an inner space, in which the hydroxyl radical generator 200 is
provided, and several sides. Preferably, as shown in FIG. 1, the body 100 has
four sidewalls, which can be hinged to open the body 100. When one sidewall
is opened, the hydroxyl radical generator 200 can be installed inside the body
100. The opened sidewall also facilitates the maintenance of the hydroxyl radical
generator 200, which will be described later.
In addition, a guideboard for pedestrians is provided inside a side frame
110 of the body 100. As described above, since the sidewall can be turned open,
the guideboard for pedestrians can be inserted into the side frame 110 by
opening the sidewall. In place of the guideboard for pedestrians, various notices,
such as a billboard and a direction board, can be posted inside the frame 110.
The air inlets 120 are also provided in the body 100, particularly, in the
lower part or the bottom of the body 100. While the air inlets 120 can have any
structure that has good ventilation, a plurality of plates can be used as each of
the air inlets 120. Preferably, the area of the plates is similar to the thickness
of the sidewall of the body 100, and the plates are inclined relative to the frame
of the air inlets 120. The inclined plates are spaced apart from each other at a
predetermined interval, so that the air can be introduced into the body 100
through openings.
Filters 121 are disposed inside the air inlets 120 as shown in FIG. 4,
which is a sectional view of the air inlets 120. When outside air is introduced
inside through the air inlets 120, the filters 121 can first remove dust from the
air. Then, the air, which is introduced in through the air inlets 120, can be
converted into hydroxyl radical-containing air through the air-cleaning hydroxyl
radical generator 200.
The air, which has a great amount of hydroxyl radicals, is exhausted
through the air outlets 130 on the upper part of the body 100. Preferably, each
of the air outlets 130 includes a plurality of plates, the area of which is similar
to the thickness of the sidewall of the body 100, as in the air inlets 120. The
plates are preferably inclined with respect to the frame of the air outlets 130.
The inclined plates are spaced apart from each other at a predetermined interval,
so that the air can exit the body 100 through openings.
As shown in FIG. 5, in the case where the air outlets 130 are provided in
the ceiling of the body 100, a roof 170 is connected to the upper part of the
body 100 by a post, and is spaced apart from the body 100, so that the air from
the hydroxyl radical generator 200 can be exhausted. Preferably, the roof
includes a first rectangular frame, which is open in the center and an edge of
which is inclined down to the right, a second rectangular frame, which is smaller
than the first rectangular frame, and a third rectangular frame, which is smaller
than the second rectangular frame and is closed in the center. The first to third
rectangular frames are connected to but spaced apart from the upper part of the
body 100 by a fixing member 180. In addition, as shown in FIG. 6, the roof 170
can be connected to the body 100 only with the fixing member 180, without a
post 160. The roof 170 not only protects the body 100 but also prevents rain
drops from entering the body 100 through the air outlets 130 of the body 100.
Furthermore, the roof can be designed to have a traditional pattern to provide an
aesthetic appearance.
Lighting devices (not shown) can be placed above the body 100 or in the
center outside the air outlets 130, so that the light from the lighting devices can
illuminate the information booth for pedestrians. Upper covers 150 are used to
focus the light, radiated from the light device, thereby uniformly illuminating the
information booth for pedestrians, as well as to prevent rain water from entering
through the air outlets 130.
The upper covers 150 can be embodied with any structure that can be
connected to the upper part of the body 100 to prevent rain water from entering
through the outlets 130 as well as to focus the light, radiated from the light
device, toward the information booth. Preferably, each of the upper covers 150
includes a plurality of panels, which are curved into the form of an arc
narrowing from bottom to top, so that a corresponding one of the lighting
devices can pass through the upper cover. The panels are preferably spaced
apart from each other at a predetermined interval, and are shaped to surround
the lighting device and a corresponding one of the air outlets 130. Preferably,
the panels are fixed to upper portions or upper sidewall portions of the body 100.
In addition, a base plate 140 is attached to the bottom of the body 100.
The base plate 140 preferably includes a plate, which is in contact with the
ground, and a supporting portion that connects the plate to the body 100. This
structure acts to absorb impacts transferred from the ground, as well as to
prevent water from entering the body 100 in the rain, thereby protecting the
guideboard for pedestrians or the signboard in the side of the body 100 and the
hydroxyl radical generator 200 inside the body 100.
The air-cleaning hydroxyl radical generator 200, which is one of the
major components of the present invention, will be described with reference to
FIGS. 2 and 3. The air-cleaning hydroxyl radical generator 200 is provided
inside the body 100 as shown in FIG. 2. Preferably, a railed shelf is provided
inside the body 100, so that the air-cleaning hydroxyl radical generator 200 is
placed on the shelf. Preferably, the shelf is provided with a hole having a size
similar to that of a fan 220, so that it does not obstruct the fan 220 from
drawing in the air.
Returning to FIG. 2, which shows the cross section of the information
booth for pedestrians, in which the air-cleaning hydroxyl radical generator 200 is
placed, the air-cleaning hydroxyl radical generator 200 includes a housing 210
having an opening in the top portion thereof, the fan 220, lamps 230 and titanium
dioxide tubes 240. The fan 220 is placed at the bottom of the housing 210 to
draw the air into the housing. The lamps 230 are placed on the upper part of
the housing to radiate photocatalyst- activating light. Each of the titanium
dioxide tubes 240 surrounds a corresponding one of the lamps 230 to generate
hydroxyl radicals in response to ultraviolet waves radiated from the lamp.
According to the principle of the air-cleaning hydroxyl radical generator
200, hydroxyl radicals (i.e., OH radicals) are generated by the combination of
light energy (of ultraviolet rays) and a photocatalyst (dioxide titanium) based on
a photochemical principle, and are also naturally obtained in small amounts in the
air. This is one type of ionization, in which ozone molecules in the atmosphere
are broken by photochemical reaction when the ozone molecules encounter
ultraviolet rays. That is, one oxygen atom is separated from one ozone molecule
and bonds with a hydrogen ion (H + ) in the moisture in the air, thereby
generating a hydroxyl radical.
Furthermore, when strong ultraviolet rays are radiated onto the surface of
the photocatalyst, oxygen and water molecules in the surrounding air are broken,
thereby forming neutral gas ions (i.e., plasma), which include hydroxyl radicals.
The hydroxyl radicals, generated as described above, perform a series of
procedures to clean the surrounding air. That is, the hydroxyl radicals deprive
carbon and hydrogen atoms from the organic materials or their chemicals, which
are harmful to humans, thereby forming stronger hydroxyl radicals.
The air-cleaning hydroxyl radical generator 200, to which the
above-mentioned photochemical principle is applied, needs a light source and the
photocatalyst as mentioned above. The present invention uses ultraviolet lamps
as the light source and titanium dioxide tubes as the photocatalyst. In the case
where the light source and the photocatalyst surrounding the light source create
a photochemical reaction, the construction, including the lamps and the titanium
dioxides, can be embodied in various forms.
Embodiment 1
The construction of this embodiment includes the lamps as the light
source and the titanium dioxide coats, formed on the lamps, as the photocatalyst.
In this construction, it is not required that the light source and the photocatalyst
be separately provided, and hydroxyl radicals can be continuously generated only
by the replacement of the lamps. Accordingly, this can facilitate the
maintenance of the air-cleaning hydroxyl radical generator 200.
Embodiment 2
FIG. 3 is a plan view of the hydroxyl radical generator 200. The
hydroxyl radical generator 200 includes the lamps 230 and the titanium dioxide
tubes 240, which surround the lamps 230 and generate hydroxyl radicals in
response to ultraviolet rays of the lamps. Furthermore, the hydroxyl radical
generator 200 also includes glass tubes 250, each of which surrounds a
corresponding pair comprising a lamp 230 and a titanium dioxide tube 240. The
glass tubes 250 can protect the lamps and the titanium dioxide tubes from
external impacts, and prevent dust in the air from gathering on the titanium
dioxide tubes 240.
Embodiment 3
Each of the lamps is placed in the center of a corresponding one of the
glass tubes, and is surrounded by a corresponding one of the titanium dioxide
tubes. Preferably, small fans, which cause the air to flow into the glass tubes,
can be provided on both sides of the glass tubes. If the small fans are not
provided, the quantity of the air flowing into the glass tubes is smaller than that
of the air drawn by the fan 220 in the bottom of the hydroxyl radical generator
200, so that the photochemical reaction is not sufficiently performed by the
moisture in the air, the photocatalyst and the light source.
Accordingly, the small fans provided inside the corresponding glass tube
can cause the air to sufficiently flow into the glass tube, thereby increasing the
quantity of hydroxyl radicals. Furthermore, a filter can be provided outside the
small fan or between the small fan and the glass tube in order to minimize the
amount of dust entering the glass tube.
It is also preferable to provide an air passage, which can help the air
introduced through the air inlets 120 rapidly reach the air-cleaning hydroxyl
radical generator 200. First and second ducts 300a and 300b, shown in FIG. 2,
act as the air passage.
The first duct 300a leads from the area surrounding the upper end of the
air inlets 120 to the area surrounding the lower end of the air- cleaning hydroxyl
radical generator 200. In addition, the air passage can be embodied by providing
a bellows between the first duct 300a and the air-cleaning hydroxyl radical
generator 200. When the bellows is connected as above, it can protect the
air-cleaning hydroxyl radical generator 200 from external impacts.
The second duct 300b leads from the area surrounding the upper end of
the air-cleaning hydroxyl radical generator 200 to the area surrounding the upper
end of the air outlets 130. In addition, as in the first duct 300a, a bellows can
be provided between the air- cleaning hydroxyl radical generator 200 and the
second duct 300b to realize the air passage.
This construction of the air passage can facilitate the flow of air, protect
the air-cleaning hydroxyl radical generator 200, and prevent the inside of the
body 100 from being polluted by dust in the air.
The preferred embodiments of the present invention have been illustrated
in the drawings and the specification. It is to be understood that the
terminology used herein is intended to be in the nature of description rather than
of limitation of the scope of the present invention defined in the claims. Those
skilled in the art will understand that many modifications and equivalents are
possible in light of the above teachings. Therefore, it is to be understood that
the scope of the present invention shall be defined by the technical idea of the
appended claims.
