[0032] Referring to FIG. 1, the cooking appliance approximately has
a cube-shaped appearance and a cavity 11 cooking a cooking object
is included inside the cooking appliance. In addition, the cooking
appliance 1 includes an electric oven, a gas range and the
like.
[0033] Further, the cavity 11 refers to a space formed by bending
and contacting a plurality of cavity plates having rectangular
plate-shapes and is formed in the rectangular shape that the front
is opened. That is, a cooking chamber 12 in which the cooking
object is cooking is formed inside the cavity 11 and the cooking
object can be inserted in or leaved out through the opened front.
In addition, the front of the cooking appliance 1 is formed with a
door 60 for opening and closing the front of the cavity 11 formed
by opening.
[0034] Meanwhile, the bottom of the cavity 11 is provided with a
lower portion heater 30 heating foods from the lower side and the
top of the cavity 10 is provided with an upper portion heater 20
heating foods from the upper portion. Further, the lower portion
heater 30 and the upper portion heater 30 may be included inside or

[0035] The back of the cavity 10 is installed with a convection
assembly 40 to discharge air heated inside the cavity 11. Further,
the convection assembly 40 includes a convection heater and a
convection fan blowing heat of the convection heater into the
cooking chamber 12.
[0036] A wire rack 90 is a kind of shelf which is formed by a
combination of a plurality of metal lines to expose the cooking
object so that the heat of the lower portion heater 30 may be
directly transmitted to the cooking object while supporting the
cooking object. In addition, the wire rack 90 is detachable coupled
with the cooking chamber 12 to be used when the cooking object is
cooked according to a specific cooking method. Specifically, the
wire rack 90 includes a main frame 92 of a rectangular shape formed
to be corresponded to the internal shape of the cavity 11 and a
plurality of beams 94 supporting the cooking object, which are
formed between the main frames 92.
[0037] Meanwhile, the cavity 11 is mounted with a wire rack fixing
section fixing the wire rack 90 to the cooking chamber. The wire
rack fixing section is formed on the cavity in various ways to fix
the wire rack, but the wire rack fixing section 70 is formed to be
protruded on the side surface of the cavity in this embodiment. In
addition, the wire rack 90 is fixed to the inside of the cooking
chamber while the lower portion of the wire rack 90 is supported to
the upper surface of the wire rack fixing section 70.
[0038] Concretely, the wire rack fixing section 70 according to
this embodiment is formed to be protruded on both sides of the
cavity in the front and back longitudinal directions. Accordingly,
the rectangular-shaped wire rack 90 is reliably supported. In
addition, the wire rack fixing section 70 may be formed to be equal
to those corresponding to the front and rear lengths of the wire
rack 90 or larger than those corresponding to the front and rear
lengths of the wire rack 90. Meanwhile, in the embodiment, the wire
rack fixing section 70 may be integrally formed on the cavity
11.
[0039] The wire rack heater 80 is mounted on the wire rack fixing
section 70 and transmits heat to the wire rack 90 while being in

80 is formed in the longitudinal direction to be exposed to the
upper surface of the wire rack fixing section 70 formed in the
longitudinal direction. In addition, the wire rack heater 80 may be
formed to be equal to those corresponding to the front and rear
direction lengths.
[0040] That is, while the lower portion of the wire rack 90 is
supported on the upper surface of the wire rack fixing section 70,
the lower portion of the wire rack 90 is in contacted with the wire
rack heater 80 mounted to be exposed to the upper surface of the
wire rack fixing section 70 and the heat generated in the wire rack
heater 80 is transmitted to the wire rack 90 by conducting.
[0041] Accordingly, the cooking object located on the upper portion
of the wire rack 90 is cooked while transmitting the heat generated
from an upper portion heater 20, a lower portion heater 30 or a
convection heater by convection and at the same time, a grill mark
according to a shape of the beam 94 of the wire rack 90 may be
formed on the surface of the cooking object by the heat directly
transmitted through the conduction from the wire rack heater 80 to
the wire rack 90.
[0042] In addition, in the wire rack heater 80, in order to
transmit an appropriate heat to the wire rack 90 for implementing a
grill mark on the cooking object located on the wire rack 90, power
density and conductivity of the heater can be set. Accordingly, the
wire heater 80 is formed to prevent the surface of the cooking
object from burning as a result that excessive heat is transmitted
to the wire rack 90.
[0043] In addition, a plurality of beams 94 supporting the cooking
object of the wire rack 90 are formed on the wire rack 90 in the
left and right directions. Accordingly, the heat of the wire rack
heater 80 formed on the side of cavity 11 is properly conducted
into beams 94 formed in left and right directions through left and
right frames 92.
[0044] In addition, in the wire rack 90, a knob 96 for attaching or
detaching the wire rack 90 of high temperature in the cooking
chamber 12 by the user may be formed on the front of the wire rack
90.
[0045] FIG. 2 is a front view illustrating a cooking appliance
before a wire rack is coupled to a cavity of a second embodiment of
the present invention, and FIG. 3 is a partial cross-sectional view
illustrating when the wire rack is coupled to the wire rack fixing
section of FIG. 2.
[0046] Referring to FIGS. 2 and 3, a wire rack fixing section 170
of the embodiment includes a support member 171 and a fixing member
173.
[0047] The support member 171 supports the lower portion of the
wire rack 90 and is generally formed in the same form as the wire
rack fixing section 70 of the first embodiment. The fixing member
173 is separated and formed by a predetermined distance from the
support member 171 and formed in the same form as the support
member 171 in general.
[0048] That is, the support member 171 and the fixing member 173 of
the embodiment are separated and formed in a length corresponding
to the thickness of the wire rack 90 and the wire rack 90 is
coupled to a space separated between the support member 171 and the
fixing member 173 while sliding. Accordingly, the wire rack 90 on
which the cooking object is located may be reliably fixed to the
cooking chamber 12.
[0049] In addition, in the embodiment, the wire rack heater 80 is
mounted to be exposed on the upper surface of the support member
171. That is, in the embodiment, while the lower portion of the
wire rack 90 is supported on the upper surface of the support
member 171, the lower portion of the wire rack 90 is in contacted
with the wire rack heater 80 mounted to be exposed on the upper
surface of the support member 171 and the heat generated in the
wire rack heater 80 is transmitted to the wire rack 90 by
conducting. In addition, the upper portion of the wire rack 90 is
fixed by the fixing member 173.
[0050] Meanwhile, the wire rack heater 80 is mounted to be exposed
on the support member 171 and is mounted in a variety of ways by
considering the efficiency of heat conductivity with the wire rack
90. In general, the wire rack heater 80 may be used as a sheath
heater and formed by penetrating into the side surface of the
cavity 11 in order to be connected with a heat source. Accordingly,
all portions exposed from the cooking chamber 12 through the side
surface of the cavity 11 are formed to be discharged through the
upper surface of the support member 171 (see FIG. 4). Accordingly,
since the area contacted with the wire rack 90 and the wire rack
heater 80 becomes wider, it is possible to be designed to have high
heat conduction.
[0051] Meanwhile, the wire rack heater 80 is formed to be exposed
to the lower surface of the fixing member 173 (see FIG. 5). In
addition, in the fixing member 173, the heat may be conducted to
the wire rack 90 by the wire rack heater 80 mounted to be exposed
on the lower surface of the fixing member 173 while fixing the
upper portion of the wire rack 90. Further, as described above, in
the wire rack heater 80, in order to widen the area contacted with
the wire rack 90 and the wire rack heater 80, all portions of the
wire rack heater 80 exposed from the inside of the cooking chamber
12 through the side surface of the cavity 11 may be also formed to
be discharged through the lower surface of the fixing member 173
(see FIG. 6).
[0052] In addition, the plurality of beams 94 supporting the
cooking object of the wire rack 90 are formed on the wire rack 90
in the left and right directions. Accordingly, the heat of the wire
rack heater 80 formed on the side surface of cavity 11 is properly
conducted into beams 94 formed in left and right directions through
left and right frames 92.
[0053] Meanwhile, in the embodiment, the wire rack fixing section
70 may be integrally formed on the cavity 11.
[0054] Hereinafter, since another configurations and operations are
