Description

Microwave Exhaust System

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven having a hood function while cooking food by high frequency and also having a hood function. Particularly, a gas oven is provided by forming an exhaust means at the rear of the microwave oven. The present invention relates to an exhaust device for a microwave oven that discharges smoke generated during cooking and has a simple structure at the same time.

In general, the microwave oven (over the stove) 100 is arranged on the upper side of the kitchen utensil 1 having a sink function and a countertop function while storing various bowls as shown in FIGS. 1 to 4. The gas oven range 200 which heat-cooks food by gas or electricity etc. is arrange | positioned under the mechanism 1.

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

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 grill member 150 to which air is sucked or discharged is disposed on an upper side of the front side, and a door member 160 to open and close the cooking chamber 120 is disposed on a lower side of the grill member 150. One side of the door member 160 is provided with an operation unit 170 equipped with various operation buttons, such as setting the operating time, stopping or heating time of the microwave oven, and one side of the main body 110 includes the gas oven 200. Exhaust means 180 for discharging the smell and smoke (referred to as the air discharge in the following) generated during the heating cooking of the food is disposed, the gas oven to facilitate food cooking on the bottom side of the main body 110 Irradiate light to the upper side of the stove (200) Is the lamp unit 190 is arranged.

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 on the ceiling side of the cooking chamber 120, a stirrer 121 for dispersing the high frequency passed through the waveguide 133 is rotatably disposed by the driving of the stirrer motor 122. One side of the magnetron 132 is equipped with a blowing means 134 for forcibly injecting outside air to cool the heat generated in the machine room 130 when the outside air flows in the oven operation, Prize One side of the magnetron (132) has a duct member 135 which guides the cooling air by the air blowing unit 134 to the inside cooking chamber 120 is disposed.

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 the exhaust air from being introduced into the cooking chamber 120 and the machine room 130. Duct section (184.185).

The exhaust duct 184 is provided with a partition member 186 to prevent the exhaust air generated from the gas oven range 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, It is sucked toward the exhaust motor 181 and discharged to the outside by a duct member (not shown).

In this case, the exhaust duct 184 and the partition member 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, the conventional microwave oven configured as described above has exhaust ducts 184 and 185 for discharging the exhaust air generated in the microwave oven and the gas oven, on the left and right sides of the main body 110, and the machine chamber 130 and the exhaust duct unit. As the partition member 186 for dividing 184 is disposed, there is a problem that the space of the machine room 130 is reduced, and the machine room is caused by the temperature of the exhaust air passing through the exhaust ducts 184 and 185. There was a problem that the temperature inside the 130 rises.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to simplify the space expansion and structure of the microwave oven by disposing exhaust means for discharging exhaust air on the rear side of the main body. It is to provide an exhaust device of the microwave oven to reduce the temperature rise by the exhaust air.
