The present invention relates to a microwave oven having a hood function at the same time by heating and cooking food by high frequency (nickname: OVER THE RANGE), in particular, the role of air suction guide and fixing the stirrer motor, exhaust vent The present invention relates to a fixing apparatus for a duct for a microwave oven, which simplifies the assembly by improving the coupling structure of the upper duct.

In general, the microwave oven (over-the-range) 100 is disposed on the upper side of the kitchen utensil 1 having a sink function and a countertop function while accommodating various dishes as shown in FIGS. 1 to 4. Under the kitchen furniture 1, a gas oven 200 for heating and cooking food by gas or electricity is disposed.

The microwave oven 100 has a hood function of discharging odor and smoke generated while heating and cooking food in the gas oven 200 while cooking food by high frequency.

The microwave oven 100 has a main body 110 forming an appearance, and inside the main body 110 is a partition wall 140 defining a cooking chamber 120 and a machine room 130, and the main body 110. The front plate 111 that forms the opening of the cooking chamber 120 is disposed on the front side of the main body 120, and the grill member 150 to which air is sucked or discharged is disposed on the front side of the main body 110. The lower side of the grill member 150 is provided with a door member 160 for opening and closing the cooking chamber 120, the one side of the door member 160, various operations such as operation of the microwave oven, stop or set the heating time An operation unit 170 provided with a button is disposed, and one side of the main body 110 includes odors and smoke generated during heating and cooking of food in the gas oven (200) (hereinafter referred to as exhaust air in the following). Exhaust means 180 for discharging is disposed, There 110 lamp unit 190 for irradiating light to the upper side of the gas oven range 200 to facilitate the cooking of food is disposed in the bottom side.

One side of the bottom of the machine room 130 is provided with a high voltage generating means 131 for generating a high pressure, the high voltage generating means on the machine room side of the partition wall 140 partitioning the cooking chamber 120 and the machine room 130. The magnetron 132 for generating a high frequency is provided by applying a high pressure of 131, and the high frequency generated from the magnetron 132 is induced into the cooking chamber 120 above the magnetron 132 and the partition wall 140. The waveguide 133 is disposed, and the stirrer 121 and the stirrer motor 122 are rotatably disposed in the upper portion of the main body 110 to disperse the high frequency passed through the waveguide 133. At the same time, the upper duct 113 for guiding the flow of the exhaust gas sucked by the exhaust means 180 and guiding the flow of external air sucked through the grill member 150 is disposed, and the magnetron 132 On one side of) Blowing means 134 is installed to forcibly suck the outside air to cool the heat generated in the machine room 130 by introducing the secondary air, the blower means on one side of the magnetron 132 The duct member 135 which guides the air cooled by 134 to the inside of the cooking chamber 120 is arrange | positioned.

The upper duct 113 is coupled to the flange portion 111b formed at the upper side of the front plate 111 through the fastening screw 115.

The exhaust means 180 is connected to a motor shaft of the exhaust motor 181 to provide an exhaust motor 181 for generating power and a suction force for rotating the exhaust motor 181 to suck the exhaust air as the exhaust motor 181 is driven. The filter member 183 disposed at the bottom side of the main body 110 to suck the exhaust air generated in the gas oven range 200 as the exhaust fan 182 and the exhaust motor 181 operate. And guides the flow of exhaust air sucked into the inside of the main body 110 through the filter member 183 and prevents exhaust air from flowing into the cooking chamber 120 and the machine room 130. It consists of duct sections 184 and 185.

The exhaust duct 184 has a side duct 186 disposed to prevent the exhaust air generated from the gas oven 200 from flowing into the machine chamber 130.

Reference numeral 136 denotes a high pressure capacitor for storing high pressure electricity, reference numeral 151 denotes an inlet for intake of outside air, and reference numeral 152 denotes an outlet for injecting air cooled in the stove.

In the conventional microwave oven configured as described above, when the exhaust motor 181 is operated by selecting the operating conditions of the operation unit 170 to discharge the food smell and smoke generated from the gas oven 200, the exhaust fan 182 The rotation, the food smell and smoke by the rotational force of the exhaust fan 182 is sucked through a plurality of filter members 183 and exhaust ducts 184, 185 disposed on the bottom side of the main body 110, And, it is sucked toward the exhaust motor 181 is discharged to the outside by the duct member (not shown).

In this case, the exhaust duct 184 and the side duct 186 prevent the exhaust air from entering and mixing inside the machine room 130, and the exhaust duct 185 also prevents the exhaust air from entering the inside of the stove. do.

However, in the conventional microwave oven configured as described above, the upper duct 113 is mounted downward from the upper side of the main body 110 to be fastened to the flange portion 111b of the front plate 111 through the fastening screw 115. There was a problem that the castle and assembly takes a long time.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to provide a fixing device of the upper duct for microwave oven to improve the assembly structure by improving the coupling structure of the upper duct and the front plate.
