5 is a control flowchart illustrating a control method of the multi-cooking microwave oven according to the present invention.

The operation of the present invention configured as described above will be described in more detail with reference to FIGS. 3 to 5 as follows.

First, as a first process, a cooking chamber for selecting a cooking menu and a desired cooking operation is selected by the user (S101). That is, the user places the cooking vessel containing food in the corresponding cooking chamber through the front of the cabinet 31 while the desired cooking chamber is opened in the first and second cooking chambers 33 and 34.

Then, while the door is closed, the user operates the key input unit 50 to set the cooking temperature and time, or simply selects a menu provided on the operation panel (not shown) to set a desired cooking temperature and cooking time and the microwave oven. Will start the operation of.

When one of the first cooking room 33 and the second cooking room 34 is individually selected by the first process, the first cooking room 33 or the second cooking room corresponding to the selected cooking menu is selected. A second process of controlling 34 is performed respectively (S102 to S105).

For example, when the first cooking chamber 33 is selected, the microcomputer 52 operates the first magnetron driver 53 and the rotation plate driver 55 according to the input of the key input unit 50 to operate the first cooking chamber ( 33) Heat / cook food inside.

At this time, the power input from the outside is supplied to the first magnetron 38 provided in the device chamber 35, so that microwaves of a predetermined frequency (2450 MHz) are generated in the first magnetron 38, so that the duct 40 The food is cooked by being discharged into the first cooking chamber 33 through the opening 41.

In addition, the motor 37 is driven by the power supply to rotate the rotary plate 36, thereby increasing the cooking efficiency by microwaves evenly transmitted to the food in the first cooking chamber (33).

On the other hand, when the second cooking chamber 34 is selected by the key input of the key input unit 50, the second magnetron 39 and the stirrer 46 are driven to perform the cooking operation as described above. Numeral 51 indicates an operation state and an operation state as described above and informs the user.

Subsequently, when the first cooking chamber 33 and the second cooking chamber 34 are simultaneously selected as the same cooking menu by the first process, the respective cooking chambers 33 and 34 are controlled under the same conditions. The third process is performed (S106-108).

That is, the same kind of food placed in the first cooking chamber 33 and the second cooking chamber 34 may be prepared by the first and second magnetrons 38 ( By simultaneously driving 39) with the same output, it is possible to quickly cook a plurality of foods of the same kind.

Meanwhile, when the first cooking chamber 33 and the second cooking chamber 34 are simultaneously selected as different cooking menus by the first process, the cooking chambers 33 and 34 are controlled under different conditions. A fourth process is performed (S109 to S110).

In this case, different kinds of foods placed in the first cooking chamber 33 and the second cooking chamber 34 may be prepared by the first magnetron 38 according to conditions such as temperature and time set in advance in the microcomputer 52. By simultaneously driving the output power of the second magnetron 39 with different outputs according to each individual menu, a plurality of different foods can be quickly cooked.

According to the multi-cooking microwave oven and the control method according to the present invention as described above, by using a microwave oven having a plurality of cooking chambers a plurality of foods can be individually cooked as a different menu or simultaneously cooked effect There is.

In addition, while using a microwave oven to cook a plurality of food, each food can be cooked simultaneously under the same conditions or different conditions, there is another effect that can reduce the time required for cooking as possible. .

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such modifications are intended to fall within the scope of the appended claims.
