Brief Description of the Drawings
[0037] The above aspects and features of the present invention will be more apparent by
describing certain embodiments of the present invention with reference to the accompanying
drawings, in which:
FIG. 1 is an exploded schematic view of the main structure of a cooking apparatus
according to the present invention;
FIG. 2 schematically shows an example of the rear space of a cooking apparatus according
to the present invention; and
FIGS. 3 and 4 schematically show other examples of the rear space of a cooking apparatus
according to the present invention.
Mode for the Invention
[0038] The present invention will be described in detail herein below with reference to
the accompanying drawings.
[0039] FIG. 1 is an exploded schematic view of the main structure of a cooking apparatus
in accordance with the present invention, showing a cooking cavity 100, a door 200,
an upper space 300 located over the cooking cavity 100, a rear space 400 located at
the rear of the cooking cavity 100, lateral spaces 500 located on both sides of the
cooking cavity 100, and a lower space 600 located under the cooking cavity 100.
[0040] The cooking cavity 100 is a space for cooking food, and is defined by an inner case
110. A heater 120 is provided at the upper portion of the inside of the cooking cavity
100, and a plate or a rack 130 is placed inside the cooking cavity 100. The inner
case 110 includes an inlet (not shown) and an outlet 111 formed on the sides for forming
an air flow path to remove heat and smell inside the cooking cavity 100. An example
of the heater 120 is a sheath heater. The use of the plate 130 in replacement of a
circular turn table brings change to width and length (depth) of the cooking cavity
100, the modification of which is restricted by the turn table. At one side of the
cooking cavity 100 is provided a guide 140 for guiding the plate 130. In addition,
at the front and rear sides of the cooking cavity 100 are provided a front frame 150
and a rear frame 160, respectively, and the front frame 150 has an opening 151 for
forming a flow path between the upper space 300 and the door 200. The rear frame 160
also has an opening 161 formed at the upper side for communication with the rear space
400.
[0041] The lower portion of the door 200 is hinged to the cooking cavity 100 so that the
door 200 can open and close the cooking cavity 100. The door 200 is formed to cover
the cooking cavity 100 and the upper space 200. The door 200 is composed of a handle
210, a front plate 220, an input sensing unit 230, a door panel 240, a control panel
250, a middle plate 260, a bracket 270, a door frame 280, and a choke cover 290.
[0042] The handle 210 is a part that a user uses to open or close the door 200, and can
be fixed to the front plate 220 by bolts (not shown). Desirably, the handle 210 has
at least one channel (not shown) formed inside along its longitudinal direction in
a manner that the channel is communicated with outside, so that the total weight can
be reduced and the amount of heat transferred to the user from the cooking cavity
100 during cooking can be minimized.
[0043] The front plate 220 is desirably made of a transparent glass for the user to be able
to see the inside of the cooking cavity 100, and a display unit (not shown) including
buttons may be attached or coated thereto, the buttons being used for the user to
select a cooking course or for the indication of an operating status of the cooking
apparatus.
[0044] The input sensing unit 230 is a part that recognizes which button is selected by
the user. In the case that the input sensing unit 230 is located at the rear of the
front plate 220 made of glass, it can be composed of a glass touch unit and serve
as an electrostatic sensor. The glass touch unit can be attached to the front plate
220 using a tape. The input sensing unit 230 is located at the upper region of the
door 200 facing the upper space 300 of the cooking cavity 100, and this structure
ensures a broader cooking cavity and helps the user easily see the inside of the cooking
cavity 100 without hindrance.
[0045] The door panel 240 is a part that fixes other components 220, 250 and the like of
the door 200, and has an opening 241 for the user to see the inside of the cooking
cavity 100. Moreover, the door panel 240 has in its lower side an outlet (not shown)
through which the flow traveling along a cooling flow path extended from a cooling
fan 420 (to be described) to the door 200 via the upper space 300 is discharged.
[0046] The control panel 250 is a part for controlling the overall operation of the cooking
apparatus according to a user input. To this end, it cooperates with the input sensing
unit 230 and a relay substrate 350 (to be described), and is fixed to the door panel
240 from the rear side of the input sensing unit 230. Desirably, the control panel
250 is provided with a light-emitting source such as an LED (light emitting diode),
and irradiates the light emitted from the light-emitting source to the display unit
(not shown).
[0047] The middle plate 260 is a part fixed to the door panel 240, while being spaced out
from the front plate 220 and the door frame 280, respectively. Its primary function
is to block heat transfer from the cooking cavity 100 to the front frame 220 and the
handle 210. Desirably, the middle plate 260 is installed at the door panel 240 so
that a flow generated from the cooling fan 420 (to be described) enters the door 200
via the rear space 400 and the upper space 300 and then travels between the middle
plate 260 and the front plate 220 under the guidance of a bracket 270 (to be described).
Such a flow vents through the outlet (not shown) of the door panel 240.
[0048] The bracket 270 is fixed to the door panel 240 from the rear side of the control
panel 250. It serves to protect the input sensing unit 230 and the control panel 250,
each including electronic components, against heat and microwaves from the cooking
cavity 100 and against the flow by the cooling fan 420, and guides the flow to travel
between the door panel 240 and the front plate 220.
[0049] The door frame 280 is accommodated in the door panel 240, and serves to block leakage
of microwaves to the outside of the cooking apparatus.
[0050] The choke cover 290 is a cover for the door 200 located towards the cooking cavity
100, and has an opening 291 formed on its upper side in correspondence to the opening
151 of the front frame 150. The opening 291 is preferably composed of tiny holes in
order to prevent food or foreign substances from getting into the door 200 while the
door 200 is being open.
[0051] The upper space 300 is a space over the cooking cavity 100 defined by an external
case 310, and includes a heater 320, a waveguide 330, an insulating upper plate 340,
and a relay substrate 350. Optionally, a lamp (not shown) for lightening the cooking
cavity 100 may be provided as well.
[0052] The external case 310 has a shape that encompasses the top and both sides of the
cooking cavity 100 at a distance away, and is connected to the front frame 150 and
the rear frame 160. If necessary, it may have an outlet 311 so that a flow having
traveled around the cooking cavity 100 and the heating elements installed in the cooking
apparatus can be vented to the outside.
[0053] An example of the heater 320 is a halogen heater. Since such a heater 320 is influenced
by microwaves, unlike the heater 120 formed of a sheath heater, the heater 320 is
installed at the upper side of the inner case 110 so as to provide heat downwardly
into the cooking cavity 100 from above.
[0054] The waveguide 330 is extended from the rear space 400 to the upper space 300, and
serves to provide microwaves generated from a magnetron (not shown) to the cooking
cavity 100. To do this, at the upper surface of the cooking cavity 100 is provided
a port 331 (see FIG. 2).
[0055] The insulating upper plate 340 prevents heat generated by the heater 120 housed in
the inner case 110 from transferring to the upper space 300, and has a shape that
covers the upper portion of the cooking cavity 100 except for the heater 320 and the
waveguide 330.
[0056] The relay substrate 350 is mounted on the insulating upper plate 340 from one side
of the upper space 300, and interworks with the control panel 250 to operate components
inclusive of the magnetron (to be described) placed at the rear space 400.
[0057] FIG. 2 schematically shows an example of the rear space of a cooking apparatus according
to the present invention. Referring to FIGS. 1 and 2, the rear space 400 is a space
behind the cooking cavity 100 defined by the cover 410, and includes a cooling fan
420, a convection heater assembly 430, and heating elements such as a magnetron 440,
a high voltage transformer 450, and a high voltage capacitor 460, together building
a component room of the cooking apparatus.
[0058] The cover 410 is connected to the rear frame 160 or the outer case 310 so as to cover
the upper space 300 and the rear space 400, and its lower portion is connected to
a base 610. At the lower portion of the cover 410 or the base 610 is provided an inlet
411 for air inflow to the cooling fan 420.
[0059] The cooling fan 420 is located at the lower portion of the rear space 400 along the
width direction thereof, and includes flow-generating units 421 and 422 on both sides
to cool the components installed at the upper side. As the rear space 400, the upper
space 300 and the door 200 are built in a way to be communicated, the entire area
of the cooking apparatus can be cooled by means of the cooling fan 420. In addition,
the cooling fan 420 is provided with a partition wall 423 for preventing the flow
generated by the cooling fan 420 from flowing back to the cooling fan 420. The partition
wall 423 has openings 424 and 425 formed on both sides in a manner to make the flow
go up to the upper portion of the rear space 400. At the space 426 between the flow-generating
units 421 and 422 is provided a motor (not shown) for driving the flow-generating
units 421 and 422.
[0060] FIGS. 3 and 4 schematically show other application examples of the rear space of
a cooking apparatus according to the present invention. Referring to FIGS. 1-4, the
rear space is provided, in addition to the structure shown in FIG. 2, with a flow
guide 441 for guiding air flow to the magnetron 440, and an flow guide 442 for guiding
the air flow coming out of the magnetron 440 to the inlet 112 that is formed on the
lateral face of the cooking cavity 100. This structure, especially the flow guide
442, makes it possible to guide the air flow generated from the cooling fan 420 into
the cooking cavity 100 stably and efficiently, and to effectively cool the magnetron,
one of core components.
[0061] The convection heater assembly 430 includes a fan 431, a heater 432, an inner heater
cover 433, an outer heater cover 434, and a motor 435. Desirably, a heat insulating
material (not shown) is placed between the inner heater cover 433 and the outer heater
cover 434. Such a convection heater assembly 430 must have the motor 435. Since the
motor 435 is installed being protruded backwardly from the rear space 400, the rear
space 400 must have a room that is deep enough at least to accommodate the motor 435.
Based on the attention to this space, such a large volume component 440, 450, and/or
460 among the major components used in the operation of the cooking apparatus can
be placed in the rear space 400. In this way, even though part of the cooking cavity
100 in the longitudinal direction is sacrificed, the cooking cavity 100 is expanded
in the lateral and vertical directions. Also, by using a plate instead of a turntable,
a cooking apparatus according to the present invention can change the height, width
and depth of the cooking cavity 100. Also, by placing the cooling fan 420 at the lower
portion of the rear space 400, a cooking apparatus according to the present invention
can utilize the rear space 400 and can cool the heating elements 440, 450, and/or
460 as well. Also, by providing the cooling fan 420 at the lower portion of the rear
space 400 and building the rear space 400, the upper space 300, the door 200, the
cooking cavity 100, and the lateral spaces 500 to be communicated with one another,
the whole part of a cooking apparatus according to the present invention can be effectively
cooled by the cooling fan 420. Also, as the cooling fan 420 is installed along the
width direction of the rear space 400, the heating elements such as the convection
heater assembly 430, the magnetron 440, the high voltage transformer 450, and the
high voltage capacitor 460, which are provided in the rear space 400, can be cooled
effectively, the flow can be traveled to the upper space 300, the lateral spaces 500
and the cooking cavity 100 and be vented through an outlet 611 formed on the base
at the lower portion of the cooking cavity 100. Also, by providing the partition wall
423 and the openings 424 and 425, a cooking apparatus according to the present invention
can form the flow path and flow and cool the heating elements, effectively and selectively.
Also, the rear frame 160 may further comprise an opening 162 for communicating the
lateral space 500. The opening 162 enables a direct air flow from the rear space 400
to the lateral space 500 and creates air flow to both sides of the rear space 400,
thereby promoting the cooling process and the air flow onto both sides of the rear
space 400.
[0062] The magnetron 440, the high voltage transformer 450, and the high voltage capacitor
460 are major components used in the operation of the cooking apparatus, each generating
a lot of heat. The magnetron 440 is placed above the opening 424, while the high voltage
transformer 450 and the high voltage capacitor 460 are placed above the opening 425.
The arrangement of these heating elements can be changed.
[0063] The lateral spaces 500 are spaces on both sides of the cooking cavity 100 defined
by the outer case 100, and they desirably communicate with the upper space 300, the
rear space 400, and the lower space 600, and also with the cooking cavity 100 through
the inlet 112 and the outlet 111. The flow generated from the cooling fan 420 travels
from the rear space 400, the upper space 300, the cooking cavity 100, the lateral
spaces 500, and eventually to the lower space 600. At this time, the flow traveling
the upper space 300 and heading to the lateral space 500 can guide the flow that came
out of the cooking cavity 100 through the outlet 111 to the lower space 600.
[0064] The lower space 600 is a space below the cooking cavity 100 defined by the base 610.
The base 610 is connected to the front frame 150 and the rear frame 160 to support
the cooking apparatus, and includes the outlet 611 so as to exhaust the flow originated
from the cooling fan 420 and the smell and heat generated in the cooking cavity 100.
Even though the lower space 600 is defined by the rear frame 160 from the rear side,
the base 610 is connected to the cover 410 over the rear frame 160. Therefore, the
base 610 also functions as a member for limiting the lower portion of the rear space
400. The location of the outlet 611 is not particularly limited, so it can be on the
side of the outlet 111, or preferably at the center of the base 610 to give a sufficiently
long flow path. Since hot air flow is vented through the outlet 611, the cooking apparatus
should not be placed on a kitchen appliance that is sensitive to heat. To protect
such a kitchen appliance from any damages due to overheated air, a plate (not shown)
may be connected to the base 610 at a distance so that heat may be exhausted in the
lateral directions.
[0065] As explained so far, according to a cooking apparatus of the present invention, the
height and width of the cooking cavity can be expanded by utilizing the rear space
of the cooking apparatus.
[0066] Also, according to a cooking apparatus of the present invention, the rear space provided
with the convection heater assembly can be utilized effectively.
[0067] Also, according to a cooking apparatus of the present invention, it is possible to
arrange heating elements such as the magnetron, the high voltage transformer, and
the high voltage capacitor in the rear space and to cool them effectively.
[0068] Also, according to a cooking apparatus of the present invention, the cooling fan
is provided at the lower portion of the rear space of the cooking apparatus, and can
cool the major components by placing them on the cooling flow path generated by the
cooling fan.
[0069] Also, according to a cooking apparatus of the present invention, by using the rack
or the plate instead of the turntable and by utilizing the rear space of the cooking
apparatus, it becomes possible to adjust the height, width and depth of the cooking
cavity.
[0070] Although the preferred embodiment of the present invention has been described, it
will be understood by those skilled in the art that the present invention should not
be limited to the described preferred embodiment, but various changes and modifications
can be made within the spirit and scope of the present invention as defined by the
appended claims.
