Its main purpose is to block heat transfer from the cooking cavity to the front panel 220 and the handle 210. Desirably, the middle plate 260 is installed in the door panel 240 so that the stream generated by the cooling fan 420 (to be described later) included in the door 200 via the rear space 400 and the upper space 300 and then moved between middle panel 260 and front panel 220, guide rails 270 (described below). This stream exits through the outlet (not shown) in the door panel 240.

Bracket 270 is attached to the door panel 240 from behind with respect to control panel 250. It is designed to protect the sensor input 230 and control panel 250 which contain electronic components from heat and microwaves from the cooking cavity 100, and from the flow generated by the cooling fan 420, and directs flow between the door panel 240 and the front panel 220.

Door frame 280 is placed in the door panel 240 and prevents the microwaves outside the cooking apparatus.

Sealing lid 290 - a cover for the door 200 facing the cooking cavity 100 having an opening 291 formed in its upper portion in accordance with the opening 151 of the front frame 150. The opening 291 is preferably made in the form of small holes, so that the food and other foreign material caught in the door 200 when it is open.

The upper space 300 - this space over the cooking cavity 100 defined by outer casing 310 and the heater 320 comprising a waveguide 330, an insulating upper plate 340 and a relay substrate 350. Optionally, it may also be arranged lamp (not shown) to illuminate the cooking cavity 100.

Outer casing 310 has a shape that encompasses the top and both sides of the cooking cavity 100 at a distance from it, and is connected to the front frame 150 and rear frame 160, respectively. If necessary, it may have an outlet 311 so that the flow that has passed around the cooking cavity 100 and the heating element installed in a cooking apparatus, it was possible to output the external environment.

An example of the heater 320 is a halogen heater. Since such a halogen heater 320 of microwave radiation, in contrast to the tubular heater 120, a heater 320 mounted in the upper part of the inner casing 110 so as to direct heat downward into the cooking cavity 100.

The waveguide 330 extends from the rear space 400 to the upper space 300, and serves to supply microwaves generated by the magnetron (not shown) in the cooking cavity 100. To do this, the upper surface of the cooking cavity 100 is a port 331 (see FIG. 2).

The insulating upper plate 340 prevents heat generated by the heater 120 disposed in the inner case 110, penetrate into the upper space 300, and has a shape which covers the upper portion of the cooking cavity 100 except for the heater 320 and the waveguide 330.

The relay substrate 350 is mounted on top of the insulating panel 340 at one side of the upper space 300 and communicates with the control panel 250 for controlling the components including the magnetron (to be described) placed at the rear space 400.

2 schematically shows an example of the rear space of the cooking apparatus of the present invention. As shown in Figures 1 and 2, the rear space 400 - this space behind the cooking cavity 100 defined by the housing 410 and comprising a cooling fan 420, a convection heater assembly 430, and heating elements such as a magnetron 440, a high voltage transformer 450 and the high voltage capacitor 460, which together form a component room of the cooking apparatus.

The housing 410 is connected to the rear frame 160 or the outer case 310 to cover the upper space 300 and the rear space 400, and its lower part is connected to the base 610. The bottom of the housing 410 or the base 610 an inlet 411 for supplying air to the cooling fan 420 .

The cooling fan 420 is located in the lower portion of the rear space 400 along the width direction on both sides comprises a flow generating units 421 and 422 to cool the components installed at the upper side. As the rear space 400, the upper space 300 and the door 200 is formed to communicate, the fan 420 can cool the entire area of ​​the cooking apparatus. Moreover, the cooling fan 420 is provided with a baffle 423 to prevent return flow generated by the fan 420 back to the fan 420. The baffle 423 has openings 424 and 425 formed on both sides so that the flow goes up to the upper portion of the rear space 400. The space 426 between the flow generating units 421 and 422 set the electric motor (not shown) for driving the flow generating units 421 and 422.

Figures 3 and 4 schematically show other examples of the rear space of the cooking apparatus of the present invention. As shown in Figures 1-4, in addition to the structure shown in Figure 2, the rear space provided with a guide 441 for guiding air flow to the magnetron 440 and the guide 442 for guiding the air flow of the exhaust from the magnetron 440 to the inlet 112, formed on the side face of the cooking cavity 100. This structure, especially the guide 442 allows the guide airflow generated by the cooling fan 420 into the cooking cavity 100 stably and efficiently, and to effectively cool the magnetron, one of the main components.

Convection heater assembly 430 includes a fan 431, a heater 432, an inner shroud 433 of the heater, an outer casing heater 434 and a motor 435. Desirably, between the inner casing 433 and outer casing 434 installed a heat insulating material (not shown). Such a convection heater assembly 430 must have the motor 435. Since the motor 435 is set so that protrudes rearward from the rear space 400, the rear space 400 must be deep enough to fit in it at least the motor. In connection with particular attention to this space, such components 440, 450 and / or 460 of large volume, used for the cooking apparatus can be placed in the rear space 400. Therefore, even if the sacrifice part of the longitudinal dimension 100 of the cooking cavity, the cooking the cavity can be enlarged in the transverse and vertical directions. Furthermore, by using a tray instead of a turntable, it is possible to change the height, width and depth of the cooking space in the cooking apparatus of the present invention. In addition, installation of the cooling fan 420 in the lower portion of the rear space 400 allows the use of the rear space 400 of the cooking apparatus of the present invention and, in addition, also to cool the heating elements 440, 450 and / or 460. In addition, installation of the cooling fan 420 the bottom of the rear space 400, and application of a construction in which rear space 400, the upper space 300, the door 200, the cooking cavity 100 and the lateral spaces 500 are communicated with each other, allows to effectively cool all of the cooking apparatus of the present invention, a cooling fan 420 . Furthermore, since the cooling fan 420 is installed along the width direction of the rear space 400, it is possible to effectively cool the heating elements, such as node 430 convection heater, a magnetron 440, a high voltage transformer 450 and the high voltage capacitor 460, which are located at the rear space 400, and the flow can be directed into the upper space 300 in the lateral spaces 500 and the cooking cavity 100 and output to the environment through the outlet 611 formed in the base at the bottom of the cooking cavity 100. Also, by the presence of baffle 423 and openings 424 and 425, the cooking apparatus of the present invention can form the flow path and the cooling air flow heating elements efficiently and selectively. Also, the rear frame 160 may further comprise an opening 162 for communication with the lateral space 500. The opening 162 creates a direct air flow from the rear space 400 to the lateral space 500 and creates air flow to both side portions of the rear space, thereby promoting the cooling process and air flow in both sides of the rear space 400.

The magnetron 440, the high voltage transformer 450 and the high voltage capacitor 260 are major components used during operation of the cooking apparatus, and each of them generates a lot of heat. The magnetron 440 is located above the opening 424, and the high voltage transformer 450 and the high voltage capacitor 460 located above the opening 425. The arrangement of these components of the heating can be changed.

Lateral space 500 - this space on both sides of the cooking cavity 100, which 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 outlet 111. The flow generated by the cooling fan 420 extends from the rear space 400, through the upper space 300, the cooking cavity 100, lateral spaces 500, and eventually enters the lower space 600. At this time the flow moving along the upper space 300 and heading to the lateral space 500 can guide effluent from the cooking cavity 100 through outlet 111 in the lower space 600.

Lower space 600 - this space below the cooking cavity 100 and a base 610. The base defined 610 is connected to the front frame 150 and rear frame 160 to support the cooking apparatus, and an outlet 611 so as to produce flow generated by the cooling fan 420 and the smell and heat generated in the cooking cavity 100. Even though the lower space 600 behind the rear frame 160 is restricted, the base 610 is connected to the housing 410 through the rear frame 160. Therefore, the base 610 also functions as a member that restricts a lower portion of the rear space 400. The position of the exhaust hole 611 is not particularly limited, so it can be located on the side of the outlet 111, or preferably in the center of the base 610 to create a relatively long flow path. Because through the hole 611 is output hot air cooking apparatus should not be placed on the kitchen devices that are sensitive to heat. To protect such a kitchen appliance from being damaged by hot air to the base 610 at a certain distance may be secured panel (not shown) so that heat is left in the lateral direction.

Figures 5 and 6 schematically show a cooling flow path of the present invention. As illustrated, the flux generated from the rear space 400 moves in the lateral spaces 500 formed on both sides of the cooking cavity 100, through the upper space 300, a part of the flow coming out of the holes 151 and is directed to the door 200. Also, another part of the flow can be directed to the lateral space 162 through an opening formed in the rear frame 160. The flow comes to the upper space 400 cools the heater 320 and relay substrate 350. Desirably, the relay substrate 350 is mounted on the insulating upper panel 340 along the flow direction to minimize flow disturbance . Flow through the side space 500 is guided to the lower space 600 and is output to the environment through the outlet 611 (see FIG. 1) formed in the center of the base 610. While particular restrictions on the position of the outlet 610 is not present, it is preferably located in center of the base region 610, since the longer the flow moves or circulates inside of the cooking apparatus, the more heat is exchanged. At this time, to protect the bottom surface on which the established cooking apparatus, the base 610 may be coupled to protection panel 612 at a distance from the base to the side stream can escape. Furthermore, the flow flowing through the side space 500, directs the output from the outlet 111 of the cooking cavity 100 to the lower space 600. At the same time, the air flow passing through the opening 291 in the sealing lid 290 moves between the faceplate 220 and a middle panel 260, guide rails 270 and exhausted through an outlet 242 formed in the lower surface of the door panel 240. The touch input unit 230 (see FIG. 1) and the control panel 250 (see FIG. 1) are closed and secured by a bracket 270 from the heat and air flow, one side of the middle panel 260 blocks the heat via air flow (at the air flow is blocked by the bracket 270, it blocks the flow of heat transfer at the sensor node 230 input and 240 control panel) and the other side of the middle panel 260 blocks heat using a fixed bed of air. As a result, the heat generated in the cooking cavity 100, is blocked and is not transferred to the outside of the door 200 and the handle 210 (see FIG. 1).

At the same time, part of the sealing lid 290 having the hole 291 may be slightly recessed relative to the door 200 to facilitate the flow of traffic from the cooking cavity 100.

As described above, in the cooking apparatus of the present invention, the control panel mounted on the door can be protected from the heat generated in the cooking cavity.

Moreover, in a cooking apparatus of the present invention, the control panel mounted on the door can be protected from the heat generated in the cooking cavity, wherein the control panel is located in the upper part of the door corresponding to the upper space of the cooking apparatus to extend the cooking cavity height and width.

Moreover, in a cooking apparatus of the present invention flow moving inside the door for cooling can be efficiently guided.

Moreover, in a cooking apparatus of the present invention, a control panel disposed on the door can be effectively protected from heat generated in the cooking cavity, and it is possible to effectively direct the flow moving inside the door for cooling.

Moreover, in a cooking apparatus of the present invention, the door can be cooled by the air flow that moves from the upper space of the cooking apparatus towards the door.

Although the above described preferred embodiments of the present invention, the skilled person will appreciate that they may be various modifications without departing from the spirit and scope of the present invention as defined by the appended claims.
