The one side vent fan 133 is connected to the air in the suction passage 121 and the air in the cooling passage 129 formed in one side of the air duct 110 and the suction hole 11b in the cavity 12, And the other side vent fan 135 can suck air from the electric field chamber 14 formed on the other side of the air duct 110.

A centrifugal fan for sucking the air in the direction of the rotational axis and discharging the air in the radial direction may be applied to the vent fans (133, 135). At this time, the vent fans 133 and 135 are disposed inside the fan housing, and the fan housing has a shape in which one side in the radial direction is opened and the side of the discharge flow path 126 is opened.

Each of the ventilation fans 133 and 135 is driven by the fan motor 131 so that air sucked through the suction passage 121 and the electric field chamber 14 is discharged through the discharge passage 126 to the room.

The door (140) may be disposed in front of the cavity (12). A filter (not shown) may be disposed on the front surface of the cavity 12 and the rear surface of the door 140 to prevent the microwave from leaking. The filter is a structured filter having various types of slots formed on the front surface of the cavity 12 and the rear surface of the door 140. The filter prevents the microwave from leaking into the gap of the door 140 by forming the L-C circuit. A gasket (not shown) may be disposed on the front surface of the door 140 or the cavity 12 to prevent leakage of heat from the inside of the cavity 12. The gasket is formed of an elastic synthetic resin material.

A guide 150 is installed on the front side of the main body 10 so that the door 140 can be reciprocally installed on the right and left sides or the upper and lower sides of the main body 10. Here, when the door 140 is installed to be reciprocally movable left and right, the guide 150 is disposed along the left and right directions. Further, when the door 140 is installed so as to be reciprocally movable up and down, the guide 150 is disposed along the vertical direction. The following description will be made with reference to a structure in which the door 140 is installed so as to be reciprocable leftward and rightward.

Since the door 140 can be opened to both sides, the door 140 can be opened to the left or right depending on the user's selection. Since the door 140 can be opened on both sides, the door 140 can be opened to the right side even if the left side of the cooking device is disposed at the wall surface, so that the degree of freedom of installing the cooking device can be significantly increased. Further, since the door 140 is opened to both sides, even if the space on the front side of the cooking appliance is relatively narrow, the door 140 can be opened or closed to allow food to be introduced or drawn out. In addition, since the door 140 is open to both sides, when the door 140 is closed, a large pressure is not generated in the cavity 12. Therefore, since the heat inside the cavity 12 is hardly discharged to the user, the risk of image burn or unpleasantness of the user can be reduced.
