The dial knob input unit 10 may be implemented as a rotatable dial knob switch, and receives a rotation signal from a user and transmits the rotation signal to the controller 30.

Here, the rotation signal refers to a user's operation signal for rotating the dial knob input unit 10 clockwise or counterclockwise.

At this time, for convenience of description, the description will be made by dividing the initial rotation signal and the subsequent rotation signal according to before and after the input time.

First, the initial rotation signal refers to a rotation signal first input to the dial knob input unit 10 by the user when the microwave oven is in a standby state, and may be a clock signal or a counterclockwise rotation signal.

The subsequent rotation signal may mean a rotation signal input from the user after the initial rotation signal is input, and may be a rotation signal in the same direction or in the opposite direction as the initial rotation signal. The subsequent rotation signal may include a plurality of rotation signals sequentially input from a user after the initial rotation signal is input.

The button input unit 20 receives an operation signal from the user and transmits it to the controller 30. The button input unit 20 may be implemented as a button switch (not shown) operated by a user's pressing force or a touch switch (not shown) operated by a user's touch.

The operation signal may include various signals for determining driving of the microwave oven, such as a cooking start signal for starting cooking and a cooking stop signal for stopping cooking.

Meanwhile, the button input unit 20 may be implemented as a separate switch from the dial knob input unit 10, but may be integrally formed with the dial knob input unit 10 and implemented as an integrated switch.

The controller 30 receives a menu according to the rotation signal and the rotation direction of the rotation signal input from the dial knob input unit 10, and outputs and displays the process of setting the menu on the display unit 40.

Then, when the operation signal is input from the button input unit 20, the control unit 30 drives the cooking driving unit 50 according to the set menu to perform cooking of food.

Here, the menu may be largely divided into a cooking menu and a cooking condition, and the cooking menu and the cooking condition may be configured to include submenus of various levels, respectively.

First, the cooking menu refers to a menu for setting various cooking functions, and may be composed of various menus provided by a conventional microwave oven.

In addition, the cooking condition means a condition for operating the cooking function selected in the cooking menu and may be information including numerical information such as cooking time, weight, and the like.

In this case, the controller 30 may receive a cooking menu and cooking conditions according to whether the rotation signal input from the dial knob input unit 10 and the rotation direction of the rotation signal change.

In addition, when the cooking condition includes numeric information, the controller 30 may directly receive the numerical information by comparing the rotation direction of the rotation signal input from the dial knob input unit 10 with a preset setting direction.

Meanwhile, a detailed process of setting the menu according to the rotation signal and the rotation direction of the rotation signal sequentially input from the dial knob input unit 10 will be described later with reference to FIGS. 2 and 3.

Referring back to FIG. 1, the display 40 displays a process of setting a menu, and the cooking driving unit 50 performs cooking by irradiating electromagnetic waves to food in the cooking chamber. The operation of the display unit 40 and the cooking driving unit 50 is controlled by the control unit 30.

In this case, the cooking driver 50 may include a magnetron driving unit (not shown) for driving the magnetron for irradiating electromagnetic waves into the cooking chamber, a tray motor (not shown) for rotating the tray in the cooking chamber, and a fan motor (not shown) for driving the cooling fan. The heater driving unit (not shown) for driving the heater may be included.

2 is a flowchart illustrating an operation of a method of controlling a microwave oven according to an embodiment of the present invention, and FIG. 3 is a process of selecting a cooking menu and a cooking time in a method of controlling a microwave oven according to an embodiment of the present invention. Is an exemplary view showing sequentially.

Hereinafter, a method of controlling a microwave oven according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3.

First, the controller 30 determines whether the microwave oven is in the standby state (S100).

Here, the standby state means a state in which the cooking menu and cooking conditions can be set without performing cooking of food, that is, a state in which the cooking driving unit 50 is not driven.

If the microwave oven is in a standby state, since the cooking menu and cooking conditions are set, the controller 30 checks whether an initial rotation signal is input from the dial knob input unit 10 (S102).

When the initial rotation signal is input from the dial knob input unit 10, the controller 30 outputs and displays a cooking menu on the display unit 40 (S104).

For example, when a clockwise initial rotation signal is input as shown in (a) of FIG. 3, the controller 30 displays a cooking menu on the display unit 40 as shown in (b) of FIG. 3. Can be displayed.

Meanwhile, as described above, the initial rotation signal may be a counterclockwise rotation signal rather than a clockwise direction.

When the subsequent rotation signal is input from the dial knob input unit 10 after the initial rotation signal is input in this way (S106), the controller 30 checks whether the rotation direction of the subsequent rotation signal is the same as the rotation direction of the initial rotation signal. (S108).

If the rotation direction of the subsequent rotation signal is the same as the rotation direction of the initial rotation signal, the controller 30 sequentially changes the cooking menu on the display unit 40 according to the sequentially input rotation signals (S110). (S104).

For example, as shown in (c) of FIG. 3, when a subsequent rotation signal in the same clockwise direction as that of the initial rotation signal is input, the control unit 40 may display " automatic cooking, " It can be displayed by changing cooking menu from "to" warm up ".

On the other hand, if the rotation direction of the subsequent rotation signal is the opposite of the rotation direction of the initial rotation signal, the control unit 30 selects the cooking menu currently displayed on the display unit 40 (S112), the display unit to receive the cooking conditions set Cooking conditions are indicated at 40 (S114).

For example, as shown in (e) of FIG. 3, when a counterclockwise subsequent rotation signal that is opposite to the previous subsequent rotation signal is input, the controller 30 is as shown in (f) of FIG. 3. Likewise, the "heating" may be selected as the cooking menu and the cooking time corresponding to the cooking condition may be displayed.

Thereafter, when the subsequent rotation signal is input from the dial knob input unit 10 (S116), the controller 30 checks whether the rotation direction of the subsequent rotation signal is the same as the preset setting direction (S118).

Here, the setting direction refers to the direction of rotation of the rotation signal for moving the digits of the numeric information when the numerical information is set, and may be selected clockwise or counterclockwise according to the intention of the designer and the applied product. . In addition, the setting direction may be set to the rotation direction for increasing the number.

If the rotation direction of the subsequent rotation signal is the same as the setting direction, the controller 30 may move the digits of the numerical information indicating the cooking condition to display on the display unit 40 (S120).

For example, when the setting direction is set to the counterclockwise direction, as shown in (g) of FIG. 3, when a subsequent rotation signal in the counterclockwise direction, which is the setting direction, is input, the controller 30 (h) of FIG. As shown in), the number of digits for the cooking time can be moved by one digit to the right and displayed.

On the other hand, if the rotation direction of the subsequent rotation signal is opposite to the setting direction, the controller 30 may increase the number of the currently selected digits to display on the display unit 40 (S122).

For example, when a subsequent rotation signal in a counterclockwise direction opposite to the setting direction is input as shown in (i) of FIG. 3, the controller 30 is selected as shown in (j) of FIG. 3. It can be displayed by increasing the number of digits by '1'.

Then, the controller 30 checks whether an operation signal is input from the button input unit 20 (S124), and when the operation signal is input, controls the cooking driver 50 to perform cooking of food (S126).

If the operation signal is not input, since the cooking condition setting is not completed yet, the controller 30 returns to step S114 of displaying the current cooking condition and continues to set the cooking condition.

In summary, the controller 30 changes and displays the cooking menu when a rotation signal in the same direction as the previously input rotation signal is input, and displays the cooking menu currently displayed when a rotation signal in a direction opposite to the previously input rotation signal is input. Select.

In addition, the controller 30 moves and displays the number of digits for the numeric information when the rotation signal in the preset setting direction is input when the numerical information is set, and when the rotation signal in the direction opposite to the setting direction is input, the presently selected digits. Display by increasing the number of.

That is, the controller 30 may receive a cooking menu or a cooking condition according to a change in the rotation direction of the rotation signal input from the dial knob input unit 10. Referring to FIG. 3, the controller 30 is input from the dial knob input unit 10. According to the rotation signal, "warm" is selected as the cooking menu, and the cooking time can be confirmed that it is set to "1 minute".

Thus, according to the control method of the microwave oven according to the present invention, when cooking food using a microwave oven, all the information such as cooking menu, cooking time, weight, etc. can be set with only the dial knob input unit 10, the user's convenience of operation Can improve.

In addition, since numerical information such as cooking time and weight can be set directly by the operation of the dial knob input unit 10, it is possible to replace the existing numeric key panel, simplifying the appearance of the control panel and reducing manufacturing cost. have.

On the other hand, the present embodiment has been described by taking the process of setting the cooking menu and the cooking time sequentially according to the rotation direction of the rotation signal input from the dial knob input unit 10 as an example, the present invention is limited to this It can be applied to menu setting of various other tree structure.

In addition, in the present embodiment, when the control unit 30 directly receives the numerical information, the rotation direction of the rotation signal input from the dial knob input unit 10 is compared with the preset setting direction, and the number of digits of the numerical information and the corresponding digits. For example, the case of setting the received number information may be changed and applied in various other ways.
