Description
TECHNICAL FIELD
[0001] The present invention relates to gas burners of radiant
heating type, and more particularly, to a burner assembly for a gas
burner of radiant heating type, in which mixed gas flows to an
entire part of a burner mat, uniformly.
BACKGROUND ART
[0002] The present invention relates to gas burners of radiant
heating type, and more particularly, to a burner assembly
therefore. In general, the gas burner of radiant heating type is a
range in which a heating object is heated with a radiant wave
emitted from a radiant body when the radiant body is heated by
burning a mixed gas of a fuel and air, to cook food.
[0003] FIG. 1 illustrates a related art gas burner of radiant
heating type, schematically. That is, the related art gas burner of
radiant heating type is provided with an oven part 10, and a top
burner part 20.
[0004] The top burner part 20 is provided with a burner assembly
shown in FIG. 2. The related art burner assembly will be described
with reference to FIG. 2.
[0005] The related art burner assembly is provided with a burner
housing 21, a glass plate 22, a mixing tube 23, a burner chamber
24, and a burner mat 25. The burner housing 21 shapes an outside of
the burner assembly, and forms a combustion space. The glass plate
22 is placed on top of the burner housing 21 to close an upper part
of the burner assembly.
[0006] The mixing tube 23 is a tube in which fuel and air are
introduced therein and mixed together, and is in communication with
the burner chamber 24. The burner chamber 24 has a closed
circumference and an opened top, for receiving the mixed gas from
the mixing tube 23, and storing the mixed gas therein. The opened
top of the burner chamber 24 is in communication with an inside
space of the burner housing 21.
[0007] The burner mat 25 is placed on the burner chamber 24, for
burning the mixed gas from the burner chamber 24. The burner mat 25
makes surface combustion of the mixed gas, and serves as a radiant
body for emitting a radiant wave.
[0008] The operation of the burner assembly will be described.
[0009] When a user ignites in a state a heating object is placed on
the glass plate 22, the fuel and air are introduced into the mixing
tube 23, and mixed therein during the fuel and air pass through the
mixing tube 23.
[0010] Then, the mixed gas is introduced into the burner chamber 24
in communication with the mixing tube 23, passes through the burner
mat 25, and blows out into the inside of the combustion space of
the burner housing 21. At the same time with this, the mixed gas is
ignited with an igniting spark generated by an igniting means (not
shown).
[0011] The mixed gas burns on a surface of the burner mat 25, and
the burner mat 25 emits a radiant wave as the burner mat 25 is
heated by the combustion. Then, the radiant wave transmits the
glass plate 22, and heats the heating object, to cook food.
[0012] However, the related art burner assembly has a problem in
that, a major portion of the mixed gas supplied to an inside of the
burner chamber 24 through the mixing tube 23 flows toward a central
part of the burner mat 25, uniform surface combustion throughout an
entire part of the burner mat 25 has failed.
[0013] Particularly, in a case the burner assembly has a large
size, for an example, if, not a small kettle, but a large cooking
container with a large surface area is heated, heating of an outer
part of the large cooking container has failed.
[0014] Moreover, in a case the gas supply is reduced for low
temperature heating, to cause an extreme shortage of the mixed gas
supplied to the burner chamber 24 compared to an area of the burner
mat 25, the combustion takes place only in a central part of the
burner mat 25 the mixed gas supply thereto is smooth, but not in an
outer part of the burner mat 25.
DISCLOSURE OF INVENTION
[0015] An object of the present invention designed to solve the
foregoing problems lies on providing a burner assembly which
enables uniform distribution of mixed gas, which is passed through
a mixing tube and supplied to an inside of the burner chamber,
throughout an entire part of the burner mat.
[0016] The object of the present invention can be achieved by
providing a burner assembly for a gas burner of radiant heating
type including a burner chamber for receiving mixed gas, a burner
mat on top of the burner chamber for making combustion, and a
baffle part between a bottom of the burner mat and a side of the
burner chamber the mixed gas is introduced into the burner chamber
therethrough, for uniform distribution of the mixed gas to an
entire part of the burner mat.
[0017] The baffle part includes a mesh form of a baffle plate in
the burner chamber, and the baffle part further includes a
supporting part for holding the baffle plate inside of the burner
chamber.

BEST MODE FOR CARRYING OUT THE INVENTION
[0032] Reference will now be made in detail to the preferred
embodiments of the present invention, examples of which are
illustrated in the accompanying drawings.
[0033] The burner assembly in accordance with a first preferred
embodiment of the present invention includes a burner chamber 140,
a burner mat 150, and a baffle part. The burner chamber 140 is
mounted on an underside of the burner housing 110 for receiving a
mixed gas mixed at the mixing tube 130. The burner chamber 140 has
an opened top. The burner chamber 140 may have a shape the same
with the related art as shown in the drawing, or modified similar
thereto. The burner mat 150 is placed on top of the burner chamber
140, for making surface combustion of the mixed gas supplied into
the burner chamber 140.
[0034] The baffle part distributes the mixed gas to all part of the
burner mat 150 uniformly. The baffle part includes a mesh form of
baffle plate 161 in the burner chamber 140. That is, the mesh form
of the baffle plate 161 distributes the mixed gas, flowing from the
mixing tube 130 toward the burner mat 150, to an entire part of the
burner mat 150, uniformly.
[0035] The baffle plate 161 divides the burner chamber 140 into an
upper space and a lower space. That is, the baffle plate 161
divides the burner chamber 140 into the lower space in
communication with the mixing tube 130 and the upper space having
the burner mat 150 therein.
[0036] Referring to FIG. 3, an edge of the baffle plate 161 may be
placed on a step formed in an inside wall of the burner chamber
140, which is liable to fall down by an external impact or
ceaseless flow of the mixed gas.
[0037] Referring to FIG. 4, to cope with this, the embodiment of
the present invention preferably provides separate supporting part
162 for supporting the baffle plate 161. In this instance, the
supporting part 162 has a bottom part fixed to a bottom of an
inside of the burner chamber 140, and a top part to support a lower
surface of the baffle plate 161.
[0038] Especially, in this case, it is preferable that the baffle
plate 161 is space from an inside wall of the burner chamber 140.
This is because a case combustion is made smoother at an outer part
of the burner mat 150 than a central part has a better uniform
heating efficiency than a case combustion is made smoother at a
central part of the burner mat 150 than an outer part.
[0039] That is, transmission of radiant heat from the outer part to
a central part of the burner mat 150 has a better combustion
efficiency than transmission of radiant heat from central part of
the burner mat 150 to the outer side. Moreover, the more combustion
at the outer part of the burner mat 150, the more favorable for
heating a large cooking container with relatively large surface
area.
[0040] Of course, as shown in FIG. 5, a flow cutoff part 161a may
be further provided in a central part of the baffle plate 161 for
cutting off an upward flow of the mixed gas, so that, as described
before, more mixed gas flows toward the outer part of the burner
mat 150. Moreover, as shown in FIG. 6, the mesh form of baffle
plate 161 may be formed to have openings formed the greater as it
goes further to an outer side from the central part.
[0041] As illustrated with different examples, though the first
embodiment of the present invention is applicable to a case the
mixing tube 130 is in communication with a bottom of the burner
chamber 140, the first embodiment of the present invention is also
applicable to a case the mixing tube 130 is in communication with a
circumferential surface of the burner chamber 140.
[0042] A burning process of the mixed gas in the burner assembly
having the first embodiment of the present invention applied
thereto will be described.
[0043] When the user ignites, gas and air are introduced into the
mixing tube 130, and mixed during the gas and air pass through the
mixing tube 130. Then, the mixed gas is introduced into the burner
chamber 140 in communication with the mixing tube 130, and blows
out into a combusting space in the burner housing 110 through the
burner mat 150. At this time, the mixed gas is ignited with an
igniting spark generated by igniting means (not shown).
[0044] In this instance, the mixed gas introduced into the burner
chamber 140 from the mixing tube 130 is distributed to entire part
of the burner mat 150 by the baffle plate 161 in the burner chamber
140. This is because the mesh form of the baffle plate 161 prevent
the mixed gas from concentrating a part of the burner mat 150
during the mixed gas passes through the baffle plate 161.
[0045] According to this, smooth surface combustion is made at the
burner mat 150, and a radiant wave from the combustion transmits
the glass plate 120, and heats a heating object, to heat entire
part, particularly, the outer part of the cooking container
uniformly, even if the cooling container is comparatively
large.
[0046] FIG. 8 illustrates a section of a burner assembly for a gas
burner of radiant heating type in accordance with a second
preferred embodiment of the present invention, schematically.
[0047] The burner assembly in accordance with a second preferred
embodiment of the present invention includes a baffle part for
distributing mixed gas to entire part of the burner mat uniformly,
having a baffle cylinder 163 in communication with the mixing tube
130. Of course, the baffle cylinder 163 may not be cylindrical, but
polygonal. The baffle cylinder 163 is provided between a bottom of
the burner mat 150 and a side of the burner chamber 140 the mixed
gas is introduced thereto, with an opened circumference.
[0048] The baffle cylinder 163 has a diameter larger than an
opening the mixed gas is introduced therethrough, and a bottom
surface fixed to a bottom surface of the burner chamber 140 around
the opening the mixed gas is introduced therethrough. The
circumference of the baffle part 163 may not be opened fully, but
of a mesh form for uniform discharge of the mixed gas.
[0049] However, the embodiment of the present invention suggests a
plurality of vanes 164 in the opened circumference of the baffle
cylinder 163 for smooth flow of the mixed gas to the outer part of
an inside of the burner chamber 140.
[0050] Referring to FIG. 9A, for providing a circulating force to a
mixed gas flow passing through the circumference of the baffle
cylinder 163, the vanes 164 are slanted in a clockwise or counter
clockwise direction when a section thereof is seen from above.
[0051] Of course, referring to FIG. 9B, for providing a circulating
force to a mixed gas flow passing through the circumference of the
baffle cylinder 163, the vanes 164 may be curved substantially in a
clockwise or counter clockwise direction when a section thereof is
seen from above.
[0052] The baffle cylinder 163 may have a top part fully closed, or
of a mesh form.
[0053] A burning process of the mixed gas in the burner assembly
having the second embodiment of the present invention applied
thereto is the same with the first embodiment, wherein the
concentration of the mixed gas to the central part of the burner
mat 150 is prevented by the baffle cylinder 163.
[0054] Moreover, the burner assembly in accordance with the second
preferred embodiment of the present invention is also applicable to
a structure in which the mixing tube 130 is in communication with a
circumference of the burner chamber 140. For an example, as shown
in FIG. 10, the baffle cylinder 163 is formed to surround a part of
an inside of the burner chamber 140 where the communication with
the mixing tube 130 is made. In this instance, the baffle cylinder
163 may be of a mesh form, or a perforated, on the whole.
[0055] FIG. 11 illustrates a section of a burner assembly for a gas
burner of radiant heating type in accordance with a third preferred
embodiment of the present invention.
[0056] The burner assembly for a gas burner of radiant heating type
in accordance with a third preferred embodiment of the present
invention includes a baffle part for uniform distribution of mixed
gas to entire part of a burner mat 150, having a cutoff plate 165
for cutting of flow of the mixed gas.
[0057] The cutoff plate is positioned in an inside space of the
burner chamber 140 close to the opening of the mixing tube 130 the
mixed gas is introduced therethrough, for cutting off upward flow
of the mixed gas.
[0058] The burner assembly further includes a supporting part 166
for supporting the cutoff plate 165. The supporting part 166 is
formed such that the cutoff plate is held in position in the inside
space of the burner chamber 140.
[0059] The burner assembly for a gas burner of radiant heating type
in accordance with a third preferred embodiment of the present
invention has a function substantially same with the burner
assembly for a gas burner of radiant heating type in accordance
with a second preferred embodiment of the present invention, and
provides a similar combustion performance.
[0060] FIG. 12 illustrates a section of a burner assembly for a gas
burner of radiant heating type in accordance with a fourth
preferred embodiment of the present invention.
[0061] The burner assembly for a gas burner of radiant heating type
in accordance with a third preferred embodiment of the present
invention includes a baffle part for uniform distribution of mixed
gas to entire part of a burner mat 150, having an impeller 167 at
an opening the mixed gas is introduced into the burner chamber 140
therethrough.
[0062] The impeller 167 may be helical substantially, or slanted in
a clockwise or counter clockwise direction, for providing a
circulating force to a mixed gas flow passing through the impeller
167. Particularly, as shown in FIG. 13, though the impeller 167 may
be on a bottom surface of an inside of the burner chamber 140 alike
the foregoing embodiment, the impeller 167 may be in the mixing
tube 130.
[0063] It will be apparent to those skilled in the art that various
modifications and variations can be made in the present invention
without departing from the spirit or scope of the invention. Thus,
it is intended that the present invention cover the modifications
and variations of this invention provided they come within the
scope of the appended claims and their equivalents.
[0064] Industrial Applicability
[0065] The burner assembly of the present invention permits uniform
combustion at the burner mat by making the mixed gas supply to the
entire part of the burner mat, uniform.
[0066] The burner assembly of the present invention permits
combustion at an outer side of the burner mat that enables uniform
heating of entire part of a cooking container, even if the cooking
container is large.
