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.

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, a user places a cooking container containing food in the cooking chamber 33 and 34 inside the cabinet 31 in a state where the desired cooking chamber 33 and 34 is opened by a door (not shown). Let's do it.

Thereafter, the microwave oven is operated as the user operates the key input unit 50 while the door 3 is closed. That is, the user sets a desired cooking temperature and cooking time by setting a temperature and time or simply selects a menu provided on an operation panel (not shown) to start the operation of the microwave oven.

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

For example, when the first cooking chamber 34 is selected, the microcomputer 52 detects the input of the key input unit 50, thereby operating the first magnetron driver 53 and the rotating plate driver 55. Food in the first cooking chamber 34 is heated / cooked.

At this time, the power input from the outside is supplied to the first magnetron 38 provided in the device room 35, the first magnetron 38 is driven, whereby microwaves of a predetermined frequency (2450MHz) is generated to The food is cooked by being discharged into the first cooking chamber 34 through the 40 and the opening 41.

In addition, the motor 37 is driven by the power supply to rotate the rotating plate 36, thereby increasing the cooking efficiency by microwaves evenly transmitted to the food in the first cooking chamber 34.

On the other hand, when the second cooking chamber 33 is selected by the key input unit 50, the second magnetron 39 and the stirrer 46 corresponding to the second cooking chamber are driven to perform the cooking operation as described above. In this case, the display unit 51 displays the operation state and the operation state as described above and informs the user.

Subsequently, when the first cooking chamber 34 and the second cooking chamber 33 are simultaneously selected as the same cooking menu by the first process, the control unit controls the cooking chambers 33 and 34 under the same conditions. Three processes are performed (S106 to 108).

That is, the same kind of food placed in the first cooking chamber 34 and the second cooking chamber 33 is prepared by the first and second magnetron 38 according to the conditions such as the same temperature and time preset by the microcomputer 52 ( 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 34 and the second cooking chamber 33 are simultaneously selected as different cooking menus by the first process, the respective cooking chambers 33 and 34 are controlled under different conditions. The fourth process is performed (S109 to S110).

At this time, the first and second foods placed in the first cooking room 34 and the second cooking room 33 are driven according to conditions such as temperature and time respectively set in the microcomputer 52. It is cooked by the magnetrons 38 and 39. At this time, the microcomputer 52 drives the first and second magnetrons 38 and 39 simultaneously with different outputs according to respective menus, thereby rapidly cooking a plurality of different foods.

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.
