EP 0 653 900 A1 describes an oven with a humidity conditioner. Herein, an absorbent, a blower for sending air to the absorbent, and a heat source for feeding thermal energy to the absorbent is provided inside a circulation duct for communicating between a suction port and a discharge port of a cooking apparatus. Electric power is supplied to the blower and the heat source from a power source. If an option "humidified cooking" is selected, a control unit operates the blower without supplying electric power to the heat source so that the moisture may be adsorbed by the adsorbent. In the humidified cooking process, the control unit supplies electric power to the heat source and operates the blower. In this case, air sucked in through the suction port is heated by the heat source and is turned into hot air. When the hot air passes through the adsorbent, it removes the moisture from the adsorbent. Because of this, hot and damp air is sent into the oven cavity from the discharge port, thereby humidifying and heating the food in the oven cavity. In a dehumidified cooking process, the control unit operates a blower to heat the food while controlling the heat source so that the air passing the heat source may not remove the moisture from the adsorbent. At this moment, steam generated from the food during cooking is led to the adsorbent from the suction port and is adsorbed by the adsorbent. As a result, the humidity in the oven cavity is maintained low, thus realizing dehumidified cooking. -

At one side of thecooking cavity 100 is provided aguide 140 for guiding theplate 130. In addition, at the front and rear sides of thecooking cavity 100 are provided afront frame 150 and arear frame 160, respectively, and thefront frame 150 has anopening 151 for forming a flow path between theupper space 300 and thedoor 200. Therear frame 160 also has anopening 161 formed at the upper side for communication with therear space 400. - The lower portion of the
door 200 is hinged to thecooking cavity 100 so that thedoor 200 can open and close thecooking cavity 100. Thedoor 200 is formed to cover thecooking cavity 100 and theupper space 200. Thedoor 200 is composed of ahandle 210, afront plate 220, an input sensing unit 230, adoor panel 240, acontrol panel 250, amiddle plate 260, abracket 270, a door frame 280, and achoke cover 290. - The
handle 210 is a part that a user uses to open or close thedoor 200, and can be fixed to thefront plate 220 by bolts (not shown). Desirably, thehandle 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 thecooking cavity 100 during cooking can be minimized. - The
front plate 220 is desirably made of a transparent glass for the user to be able to see the inside of thecooking 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. - 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 thefront plate 220 using a tape. The input sensing unit 230 is located at the upper region of thedoor 200 facing theupper space 300 of thecooking cavity 100, and this structure ensures a broader cooking cavity and helps the user easily see the inside of thecooking cavity 100 without hindrance. - The
door panel 240 is a part that fixesother components door 200, and has anopening 241 for the user to see the inside of thecooking cavity 100. Moreover, thedoor 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 thedoor 200 via theupper space 300 is discharged. - 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 thedoor panel 240 from the rear side of the input sensing unit 230.

middle plate 260 is a part fixed to thedoor panel 240, while being spaced out from thefront plate 220 and the door frame 280, respectively. Its primary function is to block heat transfer from thecooking cavity 100 to thefront frame 220 and thehandle 210. Desirably, themiddle plate 260 is installed at thedoor panel 240 so that a flow generated from the cooling fan 420 (to be described) enters thedoor 200 via therear space 400 and theupper space 300 and then travels between themiddle plate 260 and thefront plate 220 under the guidance of a bracket 270 (to be described). Such a flow vents through the outlet (not shown) of thedoor panel 240. - The
bracket 270 is fixed to thedoor panel 240 from the rear side of thecontrol panel 250. It serves to protect the input sensing unit 230 and thecontrol panel 250, each including electronic components, against heat and microwaves from thecooking cavity 100 and against the flow by the coolingfan 420, and guides the flow to travel between thedoor panel 240 and thefront plate 220. - 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. - The
choke cover 290 is a cover for thedoor 200 located towards thecooking cavity 100, and has anopening 291 formed on its upper side in correspondence to theopening 151 of thefront frame 150. Theopening 291 is preferably composed of tiny holes in order to prevent food or foreign substances from getting into thedoor 200 while thedoor 200 is being open. - The
upper space 300 is a space over thecooking cavity 100 defined by anexternal case 310, and includes aheater 320, awaveguide 330, an insulatingupper plate 340, and arelay substrate 350. Optionally, a lamp (not shown) for lightening thecooking cavity 100 may be provided as well. - The
external case 310 has a shape that encompasses the top and both sides of thecooking cavity 100 at a distance away, and is connected to thefront frame 150 and therear frame 160. If necessary, it may have anoutlet 311 so that a flow having traveled around thecooking cavity 100 and the heating elements installed in the cooking apparatus can be vented to the outside. - An example of the
heater 320 is a halogen heater. Since such aheater 320 is influenced by microwaves, unlike theheater 120 formed of a sheath heater, theheater 320 is installed at the upper side of theinner case 110 so as to provide heat downwardly into thecooking cavity 100 from above. - The
waveguide 330 is extended from therear space 400 to theupper space 300, and serves to provide microwaves generated from a magnetron (not shown) to thecooking cavity 100. To do this, at the upper surface of thecooking cavity 100 is provided a port 331 (seeFIG. 2 ). - The insulating
upper plate 340 prevents heat generated by theheater 120 housed in theinner case 110 from transferring to theupper space 300, and has a shape that covers the upper portion of thecooking cavity 100 except for theheater 320 and thewaveguide 330. - The
relay substrate 350 is mounted on the insulatingupper plate 340 from one side of theupper space 300, and interworks with thecontrol panel 250 to operate components inclusive of the magnetron (to be described) placed at therear space 400. -
FIG. 2 schematically shows an example of the rear space of a cooking apparatus according to the present invention. Referring toFIGS. 1 and2 , therear space 400 is a space behind thecooking cavity 100 defined by thecover 410, and includes a coolingfan 420, aconvection heater assembly 430, and heating elements such as amagnetron 440, ahigh voltage transformer 450, and ahigh voltage capacitor 460, together building a component room of the cooking apparatus. - The
cover 410 is connected to therear frame 160 or theouter case 310 so as to cover theupper space 300 and therear space 400, and its lower portion is connected to abase 610. At the lower portion of thecover 410 or thebase 610 is provided aninlet 411 for air inflow to the coolingfan 420. - The cooling
fan 420 is located at the lower portion of therear space 400 along the width direction thereof, and includes flow-generatingunits rear space 400, theupper space 300 and thedoor 200 are built in a way to be communicated, the entire area of the cooking apparatus can be cooled by means of the coolingfan 420. In addition, the coolingfan 420 is provided with apartition wall 423 for preventing the flow generated by the coolingfan 420 from flowing back to the coolingfan 420. Thepartition wall 423 hasopenings rear space 400. At thespace 426 between the flow-generatingunits units -
FIGS. 3 and4 schematically show other application examples of the rear space of a cooking apparatus according to the present invention. Referring toFIGS. 1-4 , the rear space is provided, in addition to the structure shown inFIG. 2 , with aflow guide 441 for guiding air flow to themagnetron 440, and anflow guide 442 for guiding the air flow coming out of themagnetron 440 to theinlet 112 that is formed on the lateral face of thecooking cavity 100. This structure, especially theflow guide 442, makes it possible to guide the air flow generated from the coolingfan 420 into thecooking cavity 100 stably and efficiently, and to effectively cool the magnetron, one of core components. - The
convection heater assembly 430 includes afan 431, aheater 432, aninner heater cover 433, anouter heater cover 434, and amotor 435. Desirably, a heat insulating material (not shown) is placed between theinner heater cover 433 and theouter heater cover 434. Such aconvection heater assembly 430 must have themotor 435. Since themotor 435 is installed being protruded backwardly from therear space 400, therear space 400 must have a room that is deep enough at least to accommodate themotor 435. Based on the attention to this space, such alarge volume component rear space 400. In this way, even though part of thecooking cavity 100 in the longitudinal direction is sacrificed, thecooking 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 thecooking cavity 100. Also, by placing the coolingfan 420 at the lower portion of therear space 400, a cooking apparatus according to the present invention can utilize therear space 400 and can cool theheating elements fan 420 at the lower portion of therear space 400 and building therear space 400, theupper space 300, thedoor 200, thecooking cavity 100, and thelateral 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 coolingfan 420. Also, as the coolingfan 420 is installed along the width direction of therear space 400, the heating elements such as theconvection heater assembly 430, themagnetron 440, thehigh voltage transformer 450, and thehigh voltage capacitor 460, which are provided in therear space 400, can be cooled effectively, the flow can be traveled to theupper space 300, thelateral spaces 500 and thecooking cavity 100 and be vented through anoutlet 611 formed on the base at the lower portion of thecooking cavity 100. Also, by providing thepartition wall 423 and theopenings rear frame 160 may further comprise anopening 162 for communicating thelateral space 500. Theopening 162 enables a direct air flow from therear space 400 to thelateral space 500 and creates air flow to both sides of therear space 400, thereby promoting the cooling process and the air flow onto both sides of therear space 400. - The
magnetron 440, thehigh voltage transformer 450, and thehigh voltage capacitor 460 are major components used in the operation of the cooking apparatus, each generating a lot of heat. Themagnetron 440 is placed above theopening 424, while thehigh voltage transformer 450 and thehigh voltage capacitor 460 are placed above theopening 425. The arrangement of these heating elements can be changed. - The
lateral spaces 500 are spaces on both sides of thecooking cavity 100 defined by theouter case 100, and they desirably communicate with theupper space 300, therear space 400, and thelower space 600, and also with thecooking cavity 100 through theinlet 112 and the outlet 111. The flow generated from the coolingfan 420 travels from therear space 400, theupper space 300, thecooking cavity 100, thelateral spaces 500, and eventually to thelower space 600. At this time, the flow traveling theupper space 300 and heading to thelateral space 500 can guide the flow that came out of thecooking cavity 100 through the outlet 111 to thelower space 600. - The
lower space 600 is a space below thecooking cavity 100 defined by thebase 610. Thebase 610 is connected to thefront frame 150 and therear frame 160 to support the cooking apparatus, and includes theoutlet 611 so as to exhaust the flow originated from the coolingfan 420 and the smell and heat generated in thecooking cavity 100. Even though thelower space 600 is defined by therear frame 160 from the rear side, thebase 610 is connected to thecover 410 over therear frame 160. Therefore, thebase 610 also functions as a member for limiting the lower portion of therear space 400.
