The multi-door microwave oven according to the present invention includes a cabinet 70 having a plurality of openings formed therein, an inner case 80 installed inside the cabinet 70 to partition the cooking chamber 86 and the apparatus chamber 88; , A plurality of doors installed in the apparatus chamber 88 to irradiate microwaves to the cooking chamber 86 and a plurality of doors installed in the inner case 80 to open and close the opening of the cabinet 70. And a cooling device 110 installed in the device chamber 88 to discharge heat generated in the device chamber 88 to the outside of the cabinet 70.

Thus, when the operation is started after the food is stored in the cooking chamber 86, the food is cooked by the microwaves radiated from the heating apparatus 90, and the heat generated during the cooking operation is transferred to the outside of the apparatus chamber 88 by the cooling apparatus. Is discharged to to prevent overheating of the heating device (90).

Here, the cabinet 70 includes a base panel 71 and a main body 73 formed in a panel shape bent in a 'c' shape to be connected to both side ends of the base panel 71. When both ends of the main body 73 are coupled to both ends of the base panel 71, openings are formed in the front and the rear of the cabinet 70, so that the door 100 is installed at the front and the rear of the cabinet 70 to provide a cooking chamber. Can be opened and closed on both sides.

The base panel 71 has a plurality of first suction ports 72 formed at corners corresponding to the device chamber 88, and the main body 73 has a plurality of side surfaces corresponding to the first suction ports 72. By forming the second suction port 74, the external air introduced by the cooling device 110 may be introduced into the apparatus chamber 88 through the first suction port 72 and the second suction port 74.

In addition, the main body 73 has a discharge port 75 through which the air introduced through the first suction port 72 and the second suction port 74 is discharged, formed on the other side thereof, whereby the first suction port 72 and the second suction port are formed. Air introduced through the 74 absorbs heat from the heating device 90 to be moved at a distance between the main body 73 and the inner case 80 to be discharged to the outside of the cabinet 70 through the discharge port 75. .

As shown in FIG. 3, the inner case 80 has a first opening 82 formed to correspond to an opening formed at one side of the cabinet 70, that is, the front surface, and the other side of the cabinet 70. That is, the second opening 84 is formed to correspond to the opening formed on the rear surface.

A first seating portion 82a is formed at an end of the first opening 82, and a second seating portion 84a is formed at an end of the second opening 84. The first seating portion 82a is formed. ) Is formed at one end of the cooking chamber 86, and the second seating portion 84a is formed at the other end of the cooking chamber 86.

In addition, the door 100 may include a first door 102 rotatably installed on the first seating portion 82a and a second door 104 rotatably installed on the second seating portion 84a. By including the, it is possible to open the cooking chamber 86 in the front and rear of the cabinet 70.

Here, the first door 102 is provided with a first hinge portion 103 at an end corresponding to the first seating portion 82a and rotatably mounted to the first seating portion 82a, and the second door 104. The second hinge portion 105 is installed at an end portion corresponding to the second seating portion 84a to be rotatably mounted to the second seating portion 84a.

Thus, the first door 102 and the second door 104 can open and close the first opening 82 and the second opening 84, the hinge portion and the seating portion on the other side of the cooking chamber 86, respectively Since the user can open the first door 102 and the second door 104 in the same direction, the user can open the cooking chamber 86 easily.

The heating device 90 is a magnetron 92 that is installed in the apparatus chamber 88 to generate microwaves, and is installed between the magnetron 92 and the cooking chamber 86 to generate microwaves generated in the magnetron 92. 86) and a high pressure transformer 96 and a high voltage capacitor 98 for boosting the voltage of the current supplied from the power supply to the magnetron 92 and guiding the waveguide 94 to be guided inward.

The cooling device 110 is installed to discharge the heat generated from the heating device to the outside of the cabinet 70, the cooling device 110 is inside the first suction port 72 and the second suction port 74. Cooling fan 112 is installed, the motor 114 is connected to the rotating shaft of the cooling fan 112, the cooling fan 112 and the motor 114 is installed to the base 71 and the inner case 80 It is configured to include a bracket 116 mounted on.

Here, the bracket 116 is disposed to be inclined at an angle so that the first suction port 72 and the second suction port 74 correspond to each other, and as shown in FIG. 2, the cooling fan 112 has the first suction port 72. ) And the second suction port 74 so as to be spaced apart from the suction port by a predetermined amount.

Thus, the air introduced into the device through the first inlet 72 and the second inlet 74 is in contact with the magnetron 92, the high pressure transformer 96, and the high pressure capacitor 98 by the cooling fan 112. While absorbing heat and flowing at intervals between the inner case 80 and the cabinet 70 is discharged to the outside through the discharge port 75 formed on the side of the cabinet 70.

It is stepped up to supply the high voltage power to the magnetron 92.

As the magnetron 92 is driven by the high-voltage power supplied in this way, microwaves are generated, and the microwaves are irradiated into the cooking chamber 86 along the waveguide 94 to vibrate moisture in the food so that cooking is performed.

At this time, since the cooling fan 112 is driven by the driving of the motor 114, the outside air flows along the first intake port 72 and the second intake port 74, and the introduced air is a magnetron 92 and a high pressure transformer. 96, the heat is absorbed while being in contact with the high pressure capacitor 98 and is discharged to the outside through the discharge port 75 along the gap between the inner case 80 and the cabinet 70.

As a result, the heating device 90 may be prevented from being overheated to a predetermined temperature or more, and thus, a safe cooking operation may be achieved, and the cooling fan 112 may be inclined at an angle to the first suction port 72 and the second suction port 74. As a result, the inflow of the air is made smoothly and at the same time, the air is smoothly discharged, thereby easily discharging the high heat generated in the device chamber 88.

When the cooking operation is completed by this operation, the user may selectively open the first door 102 or the second door 104 to take out food.

According to the configuration and operation as described above, the present invention can open and close the cooking chamber 86 in various directions, it is possible to smoothly circulate the air for cooling the heating device (90).
