Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a kitchen ventilation hood
for exhausting combustion gas and smells of food, which are
generated in the kitchen, and more particularly to a kitchen
ventilation hood, which accelerates its exhaust by dividing the gas
exhausted from an exhauster and by discharging the divided gas
toward a suction port, thereby maximizing the efficiency of the
exhaust action of the kitchen ventilation hood.
[0003] 2. Description of the Related Art
[0004] Generally, kitchen ventilation hoods are installed in the
kitchen and serve to exhaust combustion gas, smells of food, steam,
etc., which are generated in cooking, to the outside, thereby
preventing air of the kitchen from being contaminated.
[0005] FIG. 5 is a side view a conventional kitchen ventilation
hood, which is installed in the kitchen.
[0006] With reference to FIG. 5, the conventional kitchen
ventilation hood 100 is installed above a gas range 200 of the
kitchen, and serves to suck combustion gas generated from the gas
range 200 and gas generated in cooking and to exhaust the gas to
the outside. The conventional kitchen ventilation hood 100
comprises a suction port 101 which is opposite to the upper surface
of the gas range 200, an exhaust fan 102 which is formed within the
kitchen ventilation hood 100, and an exhaust port 103 which is
connected to the exhaust fan 102 and serves to exhaust the gas to
the outside.
[0007] However, the aforementioned conventional kitchen ventilation
hood 100 has a problem of that the combustion gas generated from
the gas range 200 and the gas generated in cooking are not fully
exhausted to the outside but partially remain within the
kitchen.
[0008] Further, the gas remaining indoors contaminates indoor air
and disperses smells of food throughout the interior of is the
kitchen.
[0009] Moreover, since air is exhausted to the outside through the
conventional kitchen ventilation hood provided in a closed kitchen
or room, the relative air pressure of the kitchen or the room is
lowered, thereby deteriorating an expulsive power of the kitchen
ventilation hood and not effectively exhausting the gas.

the above problems, and it is an object of the present invention to
provide a kitchen ventilation hood, which accelerates its exhaust
by dividing the gas exhausted from an exhauster and by discharging
the divided gas toward a suction port, thereby maximizing the
efficiency of the exhaust action of the kitchen ventilation
hood.
[0011] It is another object of the present invention to provide a
kitchen ventilation hood in which the divided gas is easily
transferred from a duct to a discharge port of an exhaust
acceleration unit.
[0012] It is yet another object of the present invention to provide
a kitchen ventilation hood in which the divided gas is horizontally
discharged from the discharge port to the suction port.
[0013] In accordance with the present invention, the above and
other objects can be accomplished by the provision of a kitchen
ventilation hood in which an exhaust fan is installed within its
case, a suction port is formed on the bottom surface of the case
and sucks gas generated from the kitchen, and an exhaust port is

transferring the divided gas, one end of the duct being connected
to the dividing plate; a chamber connected to the other end of the
duct; and a discharge port connected to the chamber and formed on
the bottom surface of the exhaust acceleration unit.
[0014] Preferably, the chamber may comprise a pair of guide plates
for guiding the gas to the discharge port therein.
[0015] Further, preferably, the discharge port may comprise a guide
jaw for horizontally discharging the gas from the discharge port
along the outer surface of the suction port, and the guide jaw may

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] Now, preferred embodiments of the present invention will be
described in detail with reference to the annexed drawings.
[0023] FIG. 1 is a perspective view of a kitchen ventilation hood
in accordance with an embodiment of the present invention.
[0024] As shown in FIG. 1, the kitchen ventilation hood 1 in
accordance with the present invention comprises a conventional
exhauster 10 and an exhaust acceleration unit 20. The exhauster 10
comprises a case 11, an exhaust fan 12, a suction port 14, and an
exhaust port 13. The exhaust fan 12 is installed within the case 11
of the exhauster 10. The suction port 14 is formed on the bottom
surface of the case 11 of the exhauster 10 and sucks gas generated
from the kitchen. The exhaust port 13 is formed on the top surface
of the case 11 of the exhauster 10 and exhausts the sucked gas to
the outside.
[0025] The exhaust acceleration unit 20 comprises a dividing plate
21, a duct 22, a chamber 23, a discharge port 24, and a pair of
guide plates 25. The dividing plate 21 is formed on the exhaust
port 13 of the exhauster 10 and divides the gas exhausted by the
exhaust port 13 into two parts. One end of the duct 22 is connected
to the dividing plate 21 and one part of the gas divided by the
dividing plate 21 flows along the duct 22. One end of the chamber
23 is connected to the other end of the duct 22 within the case 11
of the exhauster 10. The discharge port 24 is formed on the other
end of the chamber 23. A pair of the guide plates 25 are installed
in the case 11 of the exhauster and guide the gas exhausted from
the duct 22 to the discharge port 24.
[0026] Herein, the exhaust acceleration unit 20 functions to
accelerate the gas generated from the kitchen to be effectively
sucked into the suction port 14.
[0027] Further, the dividing plate 21 serves to divide the gas
exhausted by the exhaust port 13 into two parts so that one part of
the exhausted gas flows into the exhaust acceleration unit 20.
Preferably, the divided gas flowing into the exhaust activation
unit 20 is 10% to 20% of the total amount of the exhausted gas.
[0028] The duct 22 serves as a channel for transferring the gas
divided by the dividing plate 21 into the chamber 23.
[0029] The chamber 23 serves as a space for collecting the divided
gas. Preferably, the chamber 23 is installed within the case 11 of
the exhauster 10.
[0030] The discharge port 24 serves as an outlet for discharging
the gas collected by the chamber 23. Preferably, the discharge port
24 is formed at the front of the bottom surface of the kitchen
ventilation hood 1. The reason for this is that the discharge port
24 discharges the collected gas at the front of the bottom surface
of the kitchen ventilation hood 1, thereby preventing the gas
generated in the kitchen from flowing into a room, and accelerates
the gas generated from the kitchen to be effectively sucked into
the suction port 14, thereby improving suction force of the suction
port 14 caused by the operation of the exhaust fan 12.
[0031] The guide plates 25 are diagonally installed within the
chamber 23 connected to the duct 22 and serve to smoothly transfer
the gas discharged from the duct 22 to the discharge port 24.
[0032] Therefore, the gas generated from the kitchen is sucked into
the suction port 14 by the exhaust fan 12 and then divided into two
parts by the dividing plate 21. One part of the divided gas flows
along the duct 22 and then is collected in the chamber 23. The
collected gas is guided by the guide plates 25 and transferred to
the discharge port 24. The transferred gas is discharged via the
discharge port 14 at the front of the bottom surface of the kitchen
ventilation hood 1. Thereby, the kitchen ventilation hood 1 of this
embodiment of the present invention serves to accelerate the gas
generated from the kitchen to be easily sucked into the suction
port 14.
[0033] Therefore, the exhaust acceleration unit 20 improves exhaust
force of the exhaust fan 12, thereby maximizing the efficiency of
the exhaust action of the kitchen ventilation hood 1.
[0034] FIG. 2 is a cross-sectional view of the kitchen ventilation
hood in accordance with an embodiment of the present invention.
[0035] As shown in FIG. 2, the kitchen ventilation hood 1 in
accordance with the present invention comprises the conventional
exhauster 10 and the exhaust acceleration unit 20. The exhauster 10
comprises the case 11, the exhaust fan 12 installed within the case
11, the suction port 14 formed on the bottom surface of the case
11, and the exhaust port 13 formed on the top surface of the case
11.
[0036] The exhaust acceleration unit 20 comprises the dividing
plate 21 of longitudinally dividing the exhaust port 13, the duct
22 connected to the dividing plate 21 outside the case 11 of the
exhauster 10, the chamber 23 provided with a pair of the guide
plates 25 and connected to the duct 22 within the case 11 of the
exhauster 10, and the discharge port 24 connected to the chamber 23
and serving to discharge one part of the divided gas toward the
bottom surface of the kitchen ventilation hood 1.
[0037] Herein, the gas divided by the dividing plate 21 is
collected in the chamber 23 via the duct 22 and easily transferred
to the discharge port 24 by a pair of the guide plates 25. Then,
the transferred gas is discharged via the discharge port 24 on the
bottom surface of the kitchen ventilation hood 1.
[0038] Therefore, the discharge port 24 is preferably formed at the
front of the bottom surface of the kitchen ventilation hood 1. The
reason for this is that the gas discharged by the discharge port 24
serves as an air curtain for preventing the gas generated from the
gas range from flowing into the kitchen or the room and accelerates
the gas generated from the gas range to be easily sucked into the
suction port 14.
[0039] Therefore, the kitchen ventilation hood 1 of the present
invention comprising the exhauster 10 and the exhaust acceleration
unit 20 discharges a part of the gas, which is exhausted by the
exhauster 10, into the kitchen by the exhaust acceleration unit 20,
thereby accelerating the gas generated from the kitchen to be
easily sucked into the suction port 14, maximizing the efficiency
of the exhaust action of the exhauster 10, and refining an indoor
environment of the kitchen.
[0040] FIG. 3 is a side view of the kitchen ventilation hood, which
is installed in the kitchen, in accordance with an embodiment of
the present invention.
[0041] As shown in FIG. 3, the arrows represent flow of the gas
generated from the gas range 2 in the kitchen. The gas generated
from the gas range 2 is sucked into the suction port 14 by the
suction force of the exhaust fan 12 of the kitchen ventilation hood
1, and exhausted via the exhaust port 13. The exhausted gas is
divided by the dividing plate 21, and a part of the divided gas is
collected in the chamber 23 via the duct 22. The collected gas is
discharged from the front of the bottom surface of the ventilation
hood 1 to the upper surface of the gas range 2 through the
discharge port 24.
[0042] Herein, the gas generated from the gas range 2 in the
kitchen is easily induced toward the suction port 14 by the
discharged gas via the discharge port 24, thereby maximizing the
efficiency of the exhaust action of the exhauster 10 as well as the
kitchen ventilation hood 1, and refining the indoor environment of
the kitchen.
[0043] Further, the gas discharged from the front of the bottom
surface of the kitchen ventilation hood 1 to the upper surface of
the gas range 2 serves as an air curtain for preventing the gas
generated from the gas range 2 from flowing into the kitchen or
from being dispersed through the kitchen.
[0044] Therefore, the discharged gas via the discharge port 24
induces the gas generated from the gas range 2 in the kitchen to be
easily exhausted to the outside as well as prevents the gas
generated from the gas range 2 from flowing into the kitchen. Thus,
the combustion gas generated from the gas range 2 in the kitchen
and smells of food generated in cooking are prevented from flowing
into the kitchen or from being dispersed throughout the kitchen,
thereby refining the indoor environment of the kitchen.
[0045] FIG. 4 is a cross-sectional view of a kitchen ventilation
hood in accordance with another embodiment of the present
invention.
[0046] As shown in FIG. 4, the kitchen ventilation hood of another
embodiment of the present invention comprises the exhauster 10 and
the exhaust acceleration unit 20. The exhauster 10 comprises the
case 11, the exhaust fan 12 installed within the case 11, the
suction port 14 formed on the bottom surface of the case 11, and
the exhaust port 13 formed on the top surface of the case 11.
[0047] The exhaust acceleration unit 20 comprises the dividing
plate 21 for longitudinally dividing the exhaust port 13, the duct
22 connected to the dividing plate 21 outside the case 11 of the
exhauster 10, the chamber 23 provided with a pair of the guide
plates 25 and connected to the duct 22 within the case 11 of the
exhauster 10, and the discharge port 24 connected to the chamber 23
and serving to discharge one part of the divided gas at the bottom
surface of the kitchen ventilation hood 1.
[0048] Further, a guide jaw 26 is attached to the tip of the
discharge port 24. The guide jaw 26 renders the gas discharged by
the discharge port 24 to flow horizontally.
[0049] Therefore, in order to horizontally discharge the gas along
the outer surface of the suction port 14, the guide jaw 26 is
preferably L-shaped.
[0050] Herein, the gas discharged by the discharge port 24
horizontally flows toward the suction port 14 by the guide jaw 26,
thereby raising the pressure of the outside of the suction port 14
and generating a difference in pressure between the inside and the
outside of the suction port 14. Thus, the gas generated from the
gas range 2 is easily sucked into the suction port 14 by the
difference in pressure between the inside and the outside of the
suction port 14.
[0051] The gas generated from the gas range 2 is easily sucked into
the suction port 14, thereby improving the expulsive power of the
exhaust fan 12 and maximizing the efficiency of the exhaust action
of the kitchen ventilation hood 1.
[0052] The guide jaw 26 may be variously modified in shape within
the scope and spirit of the present invention. Preferably, the gas
discharged by the discharge port 24 flows horizontally along the
outer surface of the suction port 14 by a modification of the guide
jaw 26, thereby accelerating the gas generated from the gas range 2
to be easily sucked into the suction port 14.
[0053] That is, if the gas is discharged by guide jaw 26 so that
the discharged gas flows horizontally along the outer surface of
the suction port 14, the gas generated from the kitchen is induced
by the discharged gas by the guide jaw 26, thereby being easily
sucked into the suction port 14.
[0054] Therefore, the aforementioned induction system is generated
by the repeated circulation of the divided gas, thereby maximizing
the efficiency of the exhaust action of the kitchen ventilation
hood 1 and refining the indoor environment of the kitchen.
[0055] As apparent from the above description, the present
invention provides a kitchen ventilation hood which accelerates its
exhaust by dividing the gas exhausted from an exhauster and by
discharging the divided gas toward a suction port, thereby
maximizing the efficiency of the exhaust action of the kitchen
ventilation hood. Therefore, the kitchen ventilation hood of the
present invention entirely removes the gas generated from the
kitchen, thereby eliminating bad smells from the kitchen and
cleaning indoor air of the kitchen.
[0056] Further, the present invention provides a kitchen
ventilation hood in which the divided gas is easily transferred
from the duct to the discharge port, thereby increasing speed of
discharging the gas via the discharging port, accelerating the gas
generated from the kitchen to be easily sucked into the suction
port, and maximizing the efficiency of the exhaust action of the
kitchen ventilation hood.
[0057] Moreover, the present invention provides a kitchen
ventilation hood in which the divided gas is horizontally
discharged from the discharge port to the suction port, thereby
raising the pressure around the suction port 14, accelerating the
gas generated from the kitchen to be easily sucked into the suction
port, and maximizing the efficiency of the exhaust action of the
kitchen ventilation hood.
[0058] Although the preferred embodiments of the present invention
have been disclosed for illustrative purposes, those skilled in the
art will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope and
spirit of the invention as disclosed in the accompanying
claims.
