[0001] This application is a continuation of U.S. application Ser.
No. 16/049,444, filed on Jul. 30, 2018, which claims priority to
Korean Patent Application Serial No. 10-2018-0084894, filed on Jul.
20, 2018, the entire contents of which are hereby incorporated by
reference.
BACKGROUND
[0002] The present invention relates to an electrification
apparatus for electric dust collection and an air conditioner for a
vehicle including the same.
[0003] An air conditioner is a device for keeping the air in a
predetermined space in a most suitable condition according to use
and purpose. Generally, in the air conditioner, a compressor, a
condenser, an expansion device, and an evaporator are provided, and
a refrigeration cycle for compressing, condensing, expanding, and
evaporating a refrigerant is driven to cool or heat the
predetermined space.
[0004] The predetermined space may be variously proposed according
to the place where the air conditioner is used. For example, in a
case where the air conditioner is installed in a home or an office,
the predetermined space may be an indoor space of a house or a
building.
[0005] In addition, the predetermined space may correspond to the
interior of a vehicle. Accordingly, the air conditioner for cooling
or heating the interior of the vehicle can be classified as an air
conditioner for a vehicle.
[0006] At this time, the air conditioner or the air conditioner for
a vehicle may include an electric dust collector for electrifying
and collecting dust particles in the air. In addition, the electric
dust collector may be installed in a product other than the air
conditioner, or the like, and for example, the electric dust
collector may be installed in an air cleaner, a humidifier, or the
like. In addition, the electric dust collector can be independently
installed in the air to remove dust in the air.
[0007] At this time, the following prior art relating to an
electric dust collector installed in the air conditioner for a
vehicle has been filed and disclosed.
RELATED ART 1
[0008] 1. Korea patent publication number: 10-2016-0015640
(publication date: Feb. 15, 2016)
[0009] 2. Title of Invention: Electric dust collector for
vehicle
[0010] As described in the above-mentioned related art 1, the
electric dust collector is mounted on the vehicle air conditioner
in a state where the filter unit and the electrification unit are
integrally formed with each other. In addition, the electrification
unit includes an electrification plate having a plurality of
circular through-holes and an electrification pin installed on the
center of the through-hole. Dust particles passing through the
electrification plate and the electrification pin are electrified
and collected in the filter unit.
[0011] The related art 1 has the following problems.
[0012] (1) Since the through-hole is formed in the electrification
plate in a circular shape, the area not penetrated through the
electrification plate is relatively large. In other words, there is
a problem that a flow area of the air passing through the
electrification plate is relatively small.
[0013] (2) In addition, there is a problem that the flow rate of
the air flowing through the air conditioner for a vehicle or the
like provided with the electric dust collector is reduced and the
air conditioning efficiency decreases. In addition, in order to
generate the same air flow rate, a relatively large load is applied
to the fan installed in the vehicle air conditioner or the
like.
[0014] (3) In addition, the sucked air passes directly through the
electrification plate and the electrification pin. Accordingly,
relatively large forego matters floating in the sucked air can
block the through-hole. Accordingly, there is a problem that
stability is not ensured due to sparking in the electrification pin
or the like.
[0015] (4) In addition, as the through-hole is closed by relatively
large foreign matters, the flow rate of the air passing through the
electrification plate may be reduced. Accordingly, there is a
problem that the electrification efficiency and the air
conditioning efficiency decrease and the fan is overloaded.
SUMMARY
[0016] In order to solve such a problem, an objective of the
present embodiment is to propose as electrification apparatus for
electric dust collection maximizing the flow area of air and an air
conditioner for a vehicle including the same.

for enhancing the efficiency of dust collection or preventing
foreign matters from entering through a cover frame provided with a
mesh cover, a mesh sheet, or a mesh net, which have through-holes,
and an air conditioner for a vehicle including the same.
[0019] According to the teachings of the present invention, there
is provided an electrification apparatus for electric dust
collection including: a frame which forms an outer appearance; a
conductive microfiber which is inst led n the frame and generates
ions in the air; and conductive plates which are installed in the
frame and generate a potential difference with the conductive
microfiber. The conductive plates are disposed so as to surround
the conductive microfiber to form an electrification space in which
an electric field is generated. In this case, the electrification
space is a rectangular columnar shaped space.
[0020] In addition, the conductive microfiber is positioned at the
center of the electrification space. A separation distance between
the conductive microfiber and the conductive plates may be
different according to the direction. This is because the
conductive plates are provided in a rectangular frame shape.
[0021] Meanwhile, according to the teaching of the present
invention, an air conditioner for a vehicle including: a main body
which as a suction port and a discharge port; and an electric dust
collection assembly which is installed in the main body to remove
foreign matters from the air flowing into the suction port. The
electric dust collection assembly includes an electrification
apparatus having a plurality of conductive microfibers and
conductive plates.
[0022] At this time, the conductive plates may be provided in a
rectangular frame shape around any one of the plurality of
conductive microfibers.
[0023] According to the proposed embodiment, since the conductive
plates are provided so as to surround the conductive microfiber in
a rectangular shape, there is an advantage that a space in which
air cannot flow or is not electrified can be minimized.
[0024] In addition, there is an advantage that it is possible to
maximize the flow area. of the air to increase the flow efficiency,
and to reduce the load of the fan which forces the flow of air. In
addition, there is an advantage that the air conditioning
efficiency of the air conditioner in which the electrification
apparatus is installed can increase.
[0025] In addition, there is an advantage that it is possible to
maximize the electrification space electrified by one conductive
microfiber, thereby increasing the electrification efficiency.
[0026] In addition, there is an advantage that relatively large
foreign matters can be prevented from intruding through the frame
provided with the mesh cover, the mesh sheet, and the mesh net.
Thereby, there is an advantage that damage or the like of the
electrification apparatus due to foreign matters can be
prevented.

[0039] FIG. 1 is a view illustrating an air conditioner for a
vehicle and an electric dust collection assembly installed therein
according to a first embodiment of the present invention.
[0040] As illustrated in FIG. 1, the air conditioner tar vehicle
according to the teachings of the present invention includes a main
body 15 which forms an outer appearance. The main body may be
divided into a suction main body 11 on which the suction port 20 is
formed and a discharge main body 15 in which the discharge port 30
is formed.
[0041] The suction main body 11 and the discharge main body 15 are
connected to each other to allow air to flow. Specifically, the
suction main body 11 and the discharge main body 15 are connected
to each other so that air flows from the suction main body 11 to
the discharge main body 15. However, this is an example, and the
air conditioner 1 for a vehicle may be provided as an integral main
body.
[0042] A plurality of the suction port 20 and a plurality of the
discharge port 30 may be formed in the suction main body 11 and the
discharge main body 15, respectively.
[0043] The suction port 20 includes an indoor suction port 21 and
an outdoor suction port 22. The indoor suction port 21 is
understood as an opening through which the air inside the vehicle
provided with the air conditioner 1 for a vehicle flows into the
inside of the main body 11. In addition, it is to be understood
that the outdoor suction port 22 is an opening through which the
outside air of the vehicle flows into the inside of the main body
11.
[0044] The discharge port 30 includes a front discharge port 31 and
a defrost discharge port 32. The front discharge port 31 is
understood as an opening through which the air discharged from the
main body 11 flows into the inside of the vehicle. In addition, the
defrost discharge port 32 is understood as an opening through which
the air discharged from the main body 11 flows into the windshield
of the vehicle. Through the defrost discharge port, is possible to
remove frost formed in the windshield. of the vehicle.
[0045] This is an example, and the suction port 20 and the
discharge port 30 may be formed in various positions and. numbers.
For example, the discharge port 30 may further include a discharge
port that discharges air to the lower side of the vehicle or a
discharge port that discharges air to the rear side of the
vehicle.
[0046] In addition, the air conditioner 1 for a vehicle includes a
fan and a heat exchanger installed inside the main bodies 11 and 15
but is omitted in FIG. 1 for the convenience of illustration.
[0047] Specifically, a fan may be installed inside the suction main
body 11. In other words, the fan can be disposed adjacent to the
suction port 20. As the fan is driven, air flows into the suction
main body 11 through the suction port 20. Then, air can flow from
the suction main body 11 to the discharge main body 15.
[0048] A heat exchanger or a heater may be disposed in the
discharge main body 15. Accordingly, the air flowing into the
discharge main body 15 passes through the heat exchanger or the
like and can be cooled or heated and may be discharged to the
inside of the vehicle through the discharge port 30.
[0049] In addition, the air conditioner 1 for a vehicle may further
include a plurality of suction ports 20 and a damper (not
illustrated) for selectively opening the discharge ports 30. For
example, the damper may open any one of the indoor suction port 21
and the outdoor suction port 22 and close the other. In addition,
the damper may open at least one of the plurality of discharge
ports 30.
[0050] In addition, the air conditioner 1 for vehicle according to
the teachings of the present invention, an electric dust collection
assembly 10 is installed. The electric dust collection assembly 10
corresponds to a configuration in which dust particles or the like
in the air flowing into the air conditioner 1 for a vehicle are
electrified and collected.
[0051] At this time, the electric dust collection assembly 10 may
be installed in another product other than the air conditioner 1
for a vehicle. Accordingly, FIG. 1 corresponds to an example in
which the electric dust collection assembly 10 is installed. In
addition, the electric dust collection assembly 10 may be installed
in an independent product (for example, an air purifier) to remove
dust particles in the air.
[0052] The electric dust collection assembly 10 includes an
electrification apparatus 100 for electric dust collection
(hereinafter, electrification apparatus) and a collector 200 for
electric dust collection (hereinafter, collector).
[0053] The electrification apparatus 100 functions to electrify
foreign matters such as dust particles in the air. The collector
200 functions to collect dust particles and the like electrified by
the electrification apparatus 100 and remove dust particles and the
like from the air.
[0054] The electrification apparatus 100 includes the conductive
microfiber 120 and the conductive plate 130, which will be
described later. A high voltage is applied to the conductive
microfiber 120, and a ground electrode is applied to the conductive
plate 130.
[0055] Accordingly, the electrification apparatus 100 generates
ions in the air to form an electric field. At this time, it is
understood that the conductive plate 130 generates a potential
difference with the conductive microfiber 120 to form an electric
field. In addition, electrified particles can be collected on the
conductive plate 130.
[0056] The collector 200 may be made of various materials
collecting the electrified particles by the electrification
apparatus 100. For example, the collector 200 may be a porous fiber
filter such as a nonwoven fabric. The surface of the collector 200
may be applied, coated or attached with a conductive material.
Then, a predetermined current is applied to the collector 200, so
that the electrified dust particles and the like can be
collected.
[0057] In summary, dust particles or the like in the air passing
through the electric dust collection assembly are coupled. with the
ions generated in the electrification apparatus 100 and are
electrified. The electrified. dust particles and the like can be
collected in the electrification apparatus 100 or the collector
200.
[0058] Thus, the electrification apparatus 100 can function not
only to generate ions but also to collect electrified dust
particles and the like. Therefore, the electrification apparatus
100 may be referred to as a `primary filter` and the collector 200
as a `secondary filter`. Dust particles or the like in the air can
be removed. more easily as dust particles or the like in the air
pass through the primary filter and the secondary filter in
order.
[0059] At this time, in the electric dust collection assembly 10
according to the teachings or the present invention, the
electrification apparatus 100 and the collector 200 are provided as
separate devices, and thus is referred to as "assembly" in which a
separate device is assembled or adjacently installed.
[0060] Specifically, the electrification apparatus 100 and the
collector 200 can be produced and distributed through different
manufacturing processes and distribution processes. In addition,
the electrification apparatus 100 and the collector 200 may be
coupled to each other by a separate coupling member or the
like.
[0061] In addition, as described above, the electrification
apparatus 100 can perform both the function of generating ions and
the function of collecting dust particles. Accordingly, the
electrification apparatus 100 may be installed as an independent
product separately from the collector 200.
[0062] In other words, the electrification apparatus 100 may be
installed in a general air conditioner or other products other than
the air conditioner 1 for a vehicle. In addition, the
electrification apparatus 100 may be installed independently.
[0063] In addition, the electrification apparatus 100 and the
collector 200 may be installed in a predetermined product,
respectively. For example, the electrification apparatus 100 and
the collector 200 may be installed in the air conditioner 1 for a
vehicle, respectively.
[0064] With reference to FIG. 1, the conditioner 1 for a vehicle is
provided with a dust collection installation portion 13 on which
the electric dust collection assembly 10 is installed.
Specifically, the dust collection installation portion 13 is formed
in the suction man body 11 adjacent to the suction port 20.
Particularly, the dust collection installation portion 13 is
disposed at the lower side in the flow direction of the air flowing
into the suction port 20.
[0065] This is because the air flowing into the suction port 20 is
firstly passed through the electric dust collection assembly 10. In
summary, the air flowing into the air conditioner 1 for a vehicle
passes through the electric dust collection assembly 10 first, and
dust particles and the like can be removed. Accordingly, it is
possible to prevent foreign matters from adhering to the fan, the
heat exchanger, and the like.
[0066] In addition, the air conditioner 1 for a vehicle is provided
with a fan installation portion 12 on which the fan is installed.
Specifically, the fan installation portion 12 is formed in the
suction main body 11 adjacent to the suction port 20. Particularly,
the fan installation portion 12 is used below the flow direction of
air in the dust collection installation portion 13.
[0067] Therefore, the suction main body 11, the suction port 20,
the dust collection installation portion 13, and the fan mounting
unit 12 are disposed in order in the air flow direction.
Accordingly, the air flowing into the suction port 20 passes
through the electric dust collection assembly 10 and the fan in
order and flows into the discharge main body 15.
[0068] At this time, the electrification apparatus 100 and the
collector 200 may be installed in the dust collection installation
portion respectively. Particularly, the collector 200 is disposed
below in the flow direction of air in the electrification
apparatus. Accordingly, the air flowing into the suction port 20
can pass through the electrification apparatus 100 and the
collector 200 in order.
[0069] The electrification apparatus 100 may be installed in the
dust collection installation portion 13 in a state where the
collector 200 is seated. In other words, the electrification
apparatus 100 and the collector 200 may be overlapped and seated on
the dust collection installation portion 13.
[0070] In addition, a portion for fixing the electrification
apparatus 100 may be formed on the inside of the dust collection
installation portion 13. Accordingly, the electrification apparatus
100 may be installed in the dust collection installation portion
13, and the collector 200 may be installed in the lower portion of
the electrification apparatus 100.
[0071] As described above, the electrification apparatus 100 and
the collector 200 can be managed, respectively, since the
electrification apparatus 100 and the collector 200 are installed,
respectively. For example, the user can separate, replace, and
clean. the collector 200 only in the air conditioner 1 for a
vehicle.
[0072] In particular, the replacement cycles of the electrification
apparatus 100 and the collector 200 may be different from each
other. Generally, since a larger amount of dust particles are
collected in the collector 200, the replacement cycle of the
collector 200 can be shorter than that of the electrification
apparatus 100. Therefore, the user can replace only the collector
200 without the need to separate the electrification apparatus
100.
[0073] Hereinafter, the electrification apparatus 100 will be
described in detail.
[0074] FIGS. 2 and 3 are views illustrating an electrification
apparatus for electric dust collection according to the first
embodiment of the present invention, and FIG. 4 is an exploded view
illustrating the electrification. apparatus for electric dust
collection according to the first embodiment of the present
invention.
[0075] FIG. 2 is a front perspective view of the electrification
apparatus 100, and FIG. 3 is a rear perspective view of the
electrification apparatus 100. In addition, FIG. 4 is a front
perspective view of the electrification apparatus 100 in which the
respective components are separated.
[0076] In addition, for the convenience of explanation, FIGS. 2 to
4 illustrate X, Y, and Z axes perpendicular to each other. In this
case, the X, Y, and Z axes are illustrated to illustrate the
relationship between each other, and the (+) and (-) directions of
each axis are not distinguished.
[0077] As illustrated in FIGS. 2 to 4, the electrification
apparatus 100 includes a frame 110 which forms an outer appearance
of the electrification apparatus 100, conductive microfiber 120 and
a conductive plate 130 which are provided on the frame 110.
[0078] The frame 110 is understood as a configuration for disposing
and fixing the conductive microfiber 120 and the conductive plate
130 at predetermined positions. In addition, the frame 110 may be
mounted in a space in which the electrification apparatus 100 is
installed, for example, the dust collection installation portion 13
of the air conditioner 1 for a vehicle described above.
[0079] In addition, the frame 110 is made of nonconductive material
and may be formed of, for example, plastic. In addition, the frame
110 may be formed in various shapes through an injection process or
the like.
[0080] The conductive microfiber 120 is understood as a
configuration which is discharged by a high voltage to ionize
molecules in the air. For example, the conductive microfiber 120
can generate anions such as OH--, O--, and the like, or cations
such as H+ in the air.
[0081] The conductive microfiber 120 connected to electric wires
for applying a high voltage but are omitted in FIGS. 2 to 4 for the
sake of convenience. In addition, the conductive microfiber 120 may
be understood as one end portion of an electric wire to which a
high applied voltage is applied.
[0082] In addition, the conductive microfiber 120 includes carbon
fibers. The carbon fibers are formed into microfibers having a
diameter in the micrometer unit. When a high voltage applied to the
carbon fibers, ions are generated in the air by corona
discharge.
[0083] At this time, the conductive microfiber 120 is provided in
the form of a carbon brush in which hundreds or thousands of carbon
fibers form one bundle. Hereinafter, one conductive microfiber 120
means one carbon brush.
[0084] In addition, the conductive microfiber 120 is disposed on
the frame 110 so as to extend in the Z axis direction. At this
time, the Z-axis may correspond to an axis extending in the air
flow direction. In summary, the conductive microfiber 120 may be
disposed on the frame 110 in parallel with the flow direction of
the air.
[0085] It is understood that the conductive plate 130 forms an
electric field with the conductive microfiber 120. In addition, a
ground electric wire to which a ground electrode applied is
connected to the conductive plate 130. According between the
conductive plate 130 and the conductive microfiber 120, a potential
difference is generated. and an electric field can be formed.
[0086] In addition electrons can be moved to the ground electrode.
Accordingly, high-density ions can be generated between the
conductive microfiber 120 and the conductive plate 130. In
addition, the electrification efficiency of dust particles and the
like can be improved due to the electric field formed between the
conductive microfiber 120 and the conductive plate 130.
[0087] In addition, the conductive plate 130 is formed of a
conductive material such as metal. Accordingly, the conductive
plate 130 can be understood as a metal plate having predetermined
thickness.
[0088] In addition, since the conductive plate 130 is provided as a
flat plate having a predetermined area along the Z-axis,
predetermined dust particles and the like can be collected. In
other words, the electrified dust particles and the like can be
collected in the conductive plate 130. Therefore, the
electrification apparatus 100 can also perform a function of
collecting the electrified dust particles and the like.
[0089] In addition, the conductive plate 130 is disposed to
surround the conductive microfiber 120. Specifically, the
conductive plate 130 forms a predetermined space to surround the
conductive microfiber 120. In addition, the predetermined space may
be understood as a space in which an electric field is formed.
[0090] Hereinafter, the space formed by the conductive plate 130 is
referred to as an electrification space 132. At this time, the
electrification space 132 means space closed in the X-Y-axis
direction by the conductive plate 130 and opened in the Z-axis
direction.
[0091] In particular, the conductive plate 130 according to the
teachings of the present invention forms a square columnar space.
It should be understood that the conductive plate 130 is provided
in a square frame shape based on the conductive microfiber 120.
[0092] Specifically, the electrification space 132 has a
rectangular shape on a plane, and a rectangular columnar space
extending in the Z-axis can be formed. At this time, the
rectangular shape formed on the X-Y plane may correspond to a
square. In other words, the electrification space 132 can be
understood as a square columnar space.
[0093] The conductive microfiber 120 is positioned at the center of
the electrification space 132. Specifically, the conductive
microfiber 120 is positioned at the center of the electrification
space 132 on the X-Y plane and extend in the Z-axis.
[0094] At this time, the electrification space 132 refers to a
space formed to surround one conductive microfiber 120. Therefore,
the electrification space 132 may be formed corresponding to the
number of the conductive microfibers 120.
[0095] In summary, the conductive plate 130 forms a rectangular
cross-section perpendicular to the flow direction of air. The
conductive microfiber 120 is positioned at the center of a
rectangular cross-section.
[0096] The electrification apparatus 100 may include a plurality of
conductive microfibers 120. The conductive plate 130 may form a
plurality of electrification spaces 132 corresponding to the
plurality of conductive microfibers 120.
[0097] The plurality of conductive microfibers 120 are disposed
apart from each other in the X-Y plane. In addition, each of the
conductive microfibers 120 may be disposed at the same interval as
the neighboring conductive microfibers 120. In addition, the
plurality of conductive microfibers 120 may be arranged in parallel
with the adjacent conductive microfibers 120 along the X-axis or
the Y-axis. For example, as illustrated in FIGS. 2 to 4, six
conductive microfibers 120 can be provided.
[0098] The plurality of electrification spaces 132 are formed on
the X-Y plane in a state of being separated from each other so as
to correspond to the plurality of conductive microfibers 120. The
conductive plate 130 includes an outer plate 134 for forming the
plurality of electrification spaces 132 and an inner plate 136 for
separating the plurality of electrification spaces 132.
[0099] The outer plate 134 can be understood as a configuration
that forms an outer appearance of the conductive plate 130.
Specifically, the outer plate 134 may be provided in a rectangular
frame shape.
[0100] The outer plate 134 forms a space in which the plurality of
electrification spaces 132 are combined. Specifically, the outer
plate 134 has a rectangular shape in the X-Y plane and forms a
rectangular columnar space extending in the Z-axis.
[0101] The inner plate 136 may be understood as a configuration
that divides the space formed by the outer plate 134 into the
electrification spaces 132. According, both ends of the inner plate
136 can be connected to the outer plate 134. In particular, the
inner plate 136 extends in the X-axis or the Y-axis. For example,
the inner plate 136 may divide the space formed by the outer plate
34 into six electrification spaces 132.
[0102] At this time, the outer plate 134 and the inner plate 136
may be integrally formed with each other. Alternatively, the outer
plate 134 and the inner plate 136 may be separately fabricated and
coupled with each other.
[0103] In the electrification apparatus of the related art, the
electrification space is formed into a cylindrical shape around the
conductive microfibers. Thereby, air cannot flow between the
electrification spaces, or a death zone can be formed which cannot
be electrified.
[0104] However, in case where the electrification space is formed
into a square columnar shape as in the present invention, there is
no dead space between the electrification spaces. Therefore, the
electrification space per the same space can be maximized.
Accordingly, the flow rate of the air passing through the
electrification space can be maximized.
[0105] The frame 110 includes a main body frame 112 on which the
conductive plate 130 is installed and an installation frame 114 on
which the conductive microfibers 120 are installed.
[0106] The main body frame 112 can be understood as a configuration
that forms an outer appearance of the frame 110. In addition, the
cuter plate 134 may be fitted to the main body frame 112.
Accordingly, the main body frame 112 is provided in a shape
corresponding to the outer plate 134.
[0107] Therefore, the main body frame 112 is provided in a
rectangular frame shape as in the outer plate 134. Specifically,
the outer plate 134 is installed on the main body frame 112 such
that the outer surface of the outer plate 134 is in contact with
the inner surface of the main body frame 112.
[0108] In addition, the main body frame 112 is provided with a
plurality of fixing protrusions 112a which are in contact with the
inner surface of the outer plate 134. In addition, the outer plate
134 may be fixed to the main body frame 112 by means of a bonding
member such as a bond.
[0109] In addition, the frame 110 further includes a cover frame
116 coupled to an upper end of the main body frame 112. The cover
frame 116 may be coupled to the main body frame 112 to cover the
upper end of the outer plate 134. In other words, the outer plate
134 may be fixed in the Z-axis by coupling of the main body frame
112 and the cover frame 116.
[0110] The cover frame 116 and the main body frame 112 can be
hooked. For example, the main body frame 112 may have a hook 112b
protruding outwardly, and the cover frame 116 may be formed with a
hook groove 116a into which the hook 112b is inserted.
[0111] In addition, the main body frame 112 is formed with a frame
installation portion 112c protruding outwardly and extending along
the main body frame 112. The frame installation portion 112c may
correspond to a portion which is seated in a product on which the
electrification apparatus 100 is installed.
[0112] For example, protrusions on which the frame installation
portion 112c is seated may be formed on the inside of the dust
collection installation portion 13. Therefore, the electrification
apparatus 100 may be installed in the dust collection installation
portion 13 such that the frame installation portion 112c is seated
on the protrusion.
[0113] In addition, the frame installation portion 112c may be
formed on the outer surface of the main body frame 112. In other
words, the frame installation portion 112c may be formed on all
four surfaces forming the main body frame 112. Accordingly, the
electrification apparatus 100 can be installed by the frame
installation portion 112c irrespective of the direction which the
electrification apparatus 100 is installed in the product.
[0114] For example, the main body frame 112 or the conductive plate
130 is formed as a rectangular frame having a long surface and a
short surface. With reference to FIG. 1, the electrification
apparatus 100 is inserted into the dust collection installation
portion 13 such that end surface of the electrification apparatus
100 is disposed on both sides of the dust collection installation
portion 13. According the frame installation port on 112c formed on
the end surface of the main body frame 112 can be seated on the
inner surface of the dust collection installation portion 13.
[0115] The installation frame 114 is installed in an inside of the
main body frame 112 in a state of extending into one side. In other
words, both ends of the installation frame 114 are fixed to the
main body frame 112. In the installation frame 114, a fixing groove
114a into which the conductive microfibers 120 are inserted is
formed. At this time, the fixing grooves 114a are formed to
correspond to the number of the conductive microfibers 120.
[0116] In addition, the frame 110 may further include an auxiliary
frame 118. The auxiliary frame 118 can be understood as
configuration that maintains the rigidity of the frame 110. In
other words, the auxiliary frame 118 corresponds to a configuration
for preventing the main body frame 112 and the installation frame
114 from being deformed. Accordingly, the auxiliary frame 118 may
have various shapes according to the design and may be omitted.
[0117] As described above, the frame 110 may be formed by an
injection process. Accordingly, although the frame 110 has been
described in detail, the frame 110 may be integrally formed.
[0118] Hereinafter, the shape and arrangement of the conductive
microfibers 120 and the conductive plate 130 according to the
teachings of the present invention will be described in detail.
[0119] FIG. 5 is a view illustrating conductive microfibers and
conductive plates of an electrification apparatus for electric dust
collection according to the first embodiment of the present
invention.
[0120] FIG. 5 is a view illustrating the conductive microfibers 120
and the conductive plates 130 on the X-Y plane. At this time, the
Z-axis means direction extending vertically forward or backward
from the paper.
[0121] As described above, the conductive microfibers 120 extend in
the Z-axis and are installed to the frame 110. The conductive plate
130 has a length in the Z-axis direction so as to correspond to the
length of the conductive microfibers 120 in the Z-axis
direction.
[0122] As illustrated in FIG. 5, six conductive microfibers 120 are
provided. It is an example and it is not limited thereto. For the
convenience of explanation, the conductive microfibers 120 includes
a first microfiber 120a, a second microfiber 120b, a third
microfiber 120c, a fourth microfiber 120d, a fifth microfiber 120e,
and a sixth microfiber 120f.
[0123] The second microfiber 120b and the fourth microfiber 120d
are disposed adjacent to each other on the basis of the first
microfiber 120a. At this time, being disposed adjacently means
being disposed closest to each other.
[0124] The second microfiber 120b is spaced apart from the first
microfiber 120a in the Y-axis direction. In other words, the first
microfiber 120a and the second microfiber 120b are disposed in
parallel along the Y-axis direction. At this time, the separation
distance between the first microfiber 120a and the second
microfiber 120b is defined as an arbitrary distance `A`.
[0125] The fourth microfiber 120d is spaced apart from the first
microfiber 120a in the X-axis direction. In other words, the first
microfiber 120a and the fourth microfiber 120d are arranged in
parallel along the X-axis direction. At this time, the separation
distance between the first microfiber 120a and the fourth
microfiber 120d may correspond to A. In other words, the first
microfiber 120a is spaced apart by the same distance as the
adjacent second microfiber 120b and the fourth microfiber 120d.
[0126] The third microfiber 120c is spaced apart from the second
microfiber 120b by A in the Y-axis direction. In other words, the
first microfiber 120a, the second microfiber 120b, and the third
microfiber 120c are arranged in parallel along the Y-axis
direction.
[0127] The fifth microfiber 120e is spaced apart from the fourth
microfiber 120d by A in the Y-axis direction. In addition, the
sixth microfiber 120f is spaced apart from the fifth microfiber
120e by A in the Y-axis direction. In other words, the fourth
microfiber 120d, the fifth microfiber 120e, and the sixth
microfiber 120f are arranged. along the Y-axis direction.
[0128] The fifth microfiber 120e are spaced apart from the second
microfiber 120b by A in the X-axis direction. In addition, the
sixth microfiber 120f is spaced apart from the third microfiber
120c by A in the X-axis direction.
[0129] In summary, the first, second, fourth, and fifth microfibers
120a, 120b, 120d, and 120e correspond to vertexes of a square
having a length A on one side on the plane. The second, third,
fifth, and sixth microfibers 120b, 120c, 120e, and 120f correspond
to vertexes of a square having a length A on one side on the X-Y
plane.
[0130] As the number of the conductive microfibers 120 or the
installation space of the electrification apparatus 100 is changed,
the conductive microfibers 120 may be arranged different. However,
the plurality of conductive microfibers 120 may be disposed at
positions corresponding to vertexes of a rectangle.
[0131] In addition, as illustrated in FIG. 5, six electrification
spaces 132 corresponding to the conductive microfibers 120 are
formed on the conductive plate 130. For the convenience of
explanation, six electrification spaces 132 include first
electrification space 132a, a second electrification space 132b, a
third electrification space 132c, a fourth electrification space
132d, a fifth electrification space 132e, and a sixth
electrification space 132f.
[0132] In addition, the first to sixth electrification spaces 132
are formed to surround the first to sixth microfibers 120,
respectively. Therefore, the first to sixth microfibers 120 are
disposed at the centers of the first to sixth electrification
spaces 132, respectively. In addition, each electrification space
132 is formed in a square whose a length of each side is A.
[0133] In addition, as described above, the outer plate 134 forms
the plurality of electrification spaces 132. In other words, the
outer plate 134 forms the first to sixth electrification spaces
132.
[0134] Specifically, the outer plate 134 includes a first outer
plate 134a which extends in the X-axis direction, a second outer
plate 134b which extends in the Y-axis direction at one end of the
first outer plate 134a, and a third outer plate 134c which extends
in the X-axis direction at one end of the second outer plate
134b.
[0135] In addition, the outer plate 134 includes a fourth outer
plate 134d extending in the Y-axis direction so that the third
outer plate 134c and the first outer pirate 134a are connected to
both ends, respectively. In other words, the outer plate 134 is
formed as a rectangular frame, and the first to fourth outer plates
134 correspond to the respective corners.
[0136] Specifically, the outer plate 134 forms a rectangle which is
2A the X-axis direction and 3A in the Y-axis direction. In other
words, the first and third outer plates 134a and 134c extend in the
X-axis by 2A and the second and fourth outer plates 134b and 134d
extend in the Y-axis by 3A.
[0137] The first outer plate 134a is spaced apart from the first
and fourth fine particles 120a and 120d by A/2 in the Y-axis
direction. In addition, the third outer plate 134a is spaced apart
from the third and sixth fine particles 120c and 120f by A/2 in the
Y-axis direction.
[0138] In addition, the second outer plate 134b is spaced apart
from the first, second, and third fine particles 120a, 120b, and
120c by A/2 in the X-axis direction. In addition, the fourth outer
plate 134d spaced apart from the fourth, fifth, and sixth fine
particles 120d, 120e, and 120f by A/2 in the X-axis direction.
[0139] In addition, the inner plate 136 separates the first to
sixth electrification spaces 132. In other words, the inner plate
136 divides the first to sixth electrification spaces 132 formed by
the outer plate 134 into electrification spaces 132,
respectively.
[0140] The inner plate 136 includes first inner plate 136a and a
second inner plate 136b for connecting the second outer plate 134b
and the fourth outer plate 134d. The first inner plate 136a and the
second inner plate 136b extend in the X-axis direction and are
spaced apart from each other in the Y-axis direction.
[0141] In addition, the inner plate 136 further includes a third
inner plate 136c connecting the first outer plate 134a and the
third outer plate 134c. The third outer plate 134c extends in the
Y-axis direction through the first and second inner plates 136a and
136b.
[0142] In addition, the first and second inner plates 136a and 136b
extend in the X-axis by 2A and the third inner plate 134c extends
in the Y-axis by 3A.
[0143] The first electrification space 132a is formed by the first
and second outer plates 134a and 134b and the first and third inner
plates 136a and 136c, respectively. The second electrification
space 132b is formed by the second outer plate 134b and the first,
second and third inner plates 136a, 136b, and 136c.
[0144] At this time, as illustrated in FIG. 5, the first
electrification space 132a and the second electrification space
132b are separated from each other by the first inner plate 136a.
In other words, the first inner plate 136a is disposed between the
first electrification space 132a and the second electrification
space 132b.
[0145] Since the first inner plate 136a corresponds to a flat plate
having a very small thickness in the Z-axis direction, it can be
understood that the area of the first inner plate 136a is very
small. In other words, it can be understood that the first inner
plate 136a provides a very small influence on the air flow.
[0146] At this time, the outer plate 134 and the inner plate 136
are separately referred to, but the conductive plate 130 may
integrally formed. In addition, the conductive plate 130 may be
manufactured differently from the distinguished name.
[0147] Hereinafter, another embodiment of the electrification
apparatus 100 will be described. At this time, the same reference
numerals are used for the same configurations as those described
above, and a description thereof referred.
[0148] FIG. 6 is a view illustrating an electrification apparatus
fore electric dust collection according to a second embodiment of
the present invention, and FIG. 7 is an exploded view illustrating
the electrification apparatus for electric dust collection
according to the second embodiment of the present invention.
[0149] As illustrated in FIGS. 6 and 7, the electrification
apparatus 100 further includes a mesh cover 140. The mesh cover 140
is provided in a net shape having a plurality of openings so that,
air can flow. At this time, the mesh cover 140 functions to filter
relatively large foreign matters flowing into the electrification
apparatus 100.
[0150] The mesh cover 140 may be seated on the upper end of the
conductive plate 130. Accordingly, the mesh cover 140 may be formed
in a rectangular shape corresponding to the conductive plate
130.
[0151] Specifically, the mesh cover 140 is provided with a mesh
cover end 140a for forming an outside. The mesh cover end 140a
corresponds to a portion of the mesh cover 140. The mesh cover end
140a is seated on the upper end of the outer plate 134.
[0152] The cover frame 116 is seated on the upper surface of the
mesh cover end 140a and is coupled with the main body frame 112. In
other words, the mesh cover end 140a may be disposed between the
outer plate 134 and the cover frame 116 and fixed thereto.
Accordingly, the mesh cover 140 can be seated on the upper end of
the conductive plate 130.
[0153] In addition, the mesh cover 140 may be formed of the same
conductive material as the metal. Specifically, the mesh cover 140
may be formed of a metal wire mesh, which is air-permeable and has
conductivity. Accordingly, the ground electrode may be applied to
the mesh cover 140, as in the conductive plate 134.
[0154] In addition, a plurality of through-holes 142 may be formed
on the mesh cover 140. At this time, the through-hole 142
corresponds to an opening much larger than a plurality of openings
formed in the mesh cover 140.
[0155] In addition, the through-hole 142 may be formed in a shape
different from that of the plurality of openings formed in the mesh
cover 140 and be distinguished. For example, the plurality of
openings formed in the mesh cover 140 are formed in a square shape,
and the through-holes 142 are formed in a circular shape.
[0156] The through-hole 142 is formed in a circular shape around
the conductive microfibers 120. In other words, the conductive
microfibers 120 are disposed at the center of the through-hole 142.
The size of the through-hole 142 may be formed so as not to overlap
with the adjacent through-hole 142.
[0157] In addition, the through-holes 142 are formed in a number
corresponding to the conductive microfibers 120. For example, as
illustrated in FIGS. 6 and 7, six through-holes 142 are formed in
the mesh cover 140, corresponding to six conductive microfibers
120.
[0158] The conductive plate 130 is disposed to surround the
conductive microfibers 120 in a rectangular shape. Therefore, the
interval between the conductive microfibers 120 and the conductive
plate 130 may be different according to the direction.
[0159] Specifically, the conductive plate 130 forms a square
electrification space 132 whose each side is A. Accordingly, the
conductive microfibers 120 and the conductive plate 130 can be
arranged. at a minimum. distance A/2 and a maximum distance 2*A/2.
It is generally known that the electrification efficiency is higher
in a case where a potentia1 difference is formed at the same
distance.
[0160] At this time, the mesh cover 140 functions to form a
potential difference with the same distance based on the conductive
microfibers 120. As described above, the mesh cover 140 is in
contact with the conductive plate 130 to apply a ground
electrode.
[0161] Therefore, a potential difference is formed between the
through-hole 142 and the conductive microfibers 120. At this time,
the through-holes 142 are formed at the same distance around the
conductive microfibers 120. Therefore, a potential difference can
be formed at the same distance based on the conductive microfibers
120.
[0162] FIG. 8 is a view illustrating an electrification apparatus
for electric dust collection according to a third embodiment of the
present invention, and FIG. 9 is an exploded view illustrating the
electrification apparatus for electric dust collection according to
the third embodiment of the present invention.
[0163] As illustrated in FIGS. 8 and 9, the electrification
apparatus 100 further includes a mesh sheet 150. The mesh sheet 150
is provided in a net shape having a plurality of openings so that
air can flow. At this time, the mesh sheet 150 functions to filter
relatively large foreign matters flowing into the electrification
apparatus 100.
[0164] The mesh sheet 150 may be installed in the electrification
space 132. Accordingly, the mesh sheet 150 may be provided in a
rectangular shape corresponding to the electrification space 132.
For example, the mesh sheet 150 may be formed as a square whose one
side is A.
[0165] The mesh sheet 150 may be attached to the conductive plate
134 with predetermined bonding material. Specifically, the mesh
sheet 150 is attached to the inner surface of the conductive plate
134, which forms one electrification space 132.
[0166] In addition, the mesh sheet 150 may be formed of a material
having the same conductivity as that of the metal. Specifically,
the mesh sheet 150 may he formed of a metal mesh through which air
can flow and which has conductivity. Accordingly, ground electrode
may be applied to the mesh sheet 150, as in the conductive plate
134.
[0167] In addition, the mesh sheet 150 may have a through-hole 152
formed therein. At this time, the through-hole 152 corresponds to
an opening much larger than a plurality of openings formed in the
mesh sheet 150.
[0168] In addition, the through. holes 152 may be formed in a shape
different from a plurality of openings formed in the mesh sheet 150
and be distinguished. For example, the plurality of openings formed
in the mesh sheet 150 are formed in a square shape, and the
through-holes 152 are formed in a circular shape.
[0169] The through-hole 152 is formed in a circular shape at center
of the mesh sheet 150. Accordingly, the conductive microfibers 120
are disposed at the center of the through-hole 152.
[0170] In addition, the mesh sheet 150 is disposed in the
electrification space 132, respectively. In other words, the mesh
sheet 150 is provided in a number corresponding to the conductive
microfibers 120. For example, as illustrated in FIGS. 7 and 8,
corresponding to six conductive microfibers 120, six mesh sheets
150 are provided.
[0171] The mesh sheet 150 functions to form a potential difference
at the same distance based on the conductive microfibers 120. As
described above, the mesh sheet 150 is in contact with the
conductive plate 130 to apply a ground electrode.
[0172] Therefore, a potential difference is formed between the
through-hole 152 and the conductive microfibers 120. At this time,
the through-holes 152 are formed at the same distance around the
conductive microfibers 120. Therefore, a potential difference can
be formed at the same distance based on the conductive microfibers
120.
[0173] It can be understood that the mesh cover of the
electrification apparatus according to the second embodiment and
the mesh sheet of the electrification apparatus according to the
third embodiment have the same function. The mesh cover and the
mesh sheet may be referred to as mesh nets. However, it may be
understood that it is separated or formed integrally for the sake
of manufacturing and that the position of installation is
changed.
[0174] FIG. 10 is a view illustrating an electrification apparatus
for electric dust collection according to a fourth embodiment of
the present invention, and FIG. 11 is an exploded view illustrating
the electrification apparatus for electric dust collection
according to the fourth embodiment of the present invention.
[0175] As illustrated in FIGS. 10 and 11, a mesh net 117 is
installed on the cover frame 116. The mesh network 117 is provided
in a shape having a plurality of openings so that air can flow. At
this time, the cover frame 117 functions to filter relatively large
foreign matters flowing into the electrification apparatus 100.
[0176] In addition, the cover frame 116 may further include a mesh
net support portion 117a for supporting the mesh net 117. The
shape, the number, and the like of the mesh net support portion
117a may be variously provided and may be omitted.
[0177] As described above, the cover frame 116 functions to be
coupled with the main body frame 112 and fix the conductive plate
130. The mesh frame 117 is provided on the cover frame 116 so that
the cover frame 116 can function as a top cover of the
electrification apparatus 100.
[0178] In other words, the cover frame 116 forms the upper end of
the electrification apparatus 100 to prevent foreign matter from
entering or damage or the like of the electrification apparatus 100
due to foreign matters can be prevented.
[0179] As described above, the electrification apparatus 100 may
further include various configurations or be modified into various
shapes. The above description is exemplary and the electrification
apparatus 100 may be formed in more various embodiments.
