3 is a flowchart illustrating a control method of a double door microwave oven according to an embodiment of the present invention.

In this embodiment, the basic state of the second key input unit 20 is a state in which the key can be freely input while the locked state is released.

At this time, the first key input unit 10 determines whether the lock key is input (S21).

For example, in order for a clerk to perform cooking through a microwave oven, first, a lock key is input by the first key input unit 10 to limit the key input of the second key input unit 20.

When the lock key is input as described above, the second key input unit 20 is set to the locked state so that the second key input unit 20 cannot perform key input and displays it (S22).

That is, while the clerk sets the cooking conditions through the first key input unit 10, the customer cannot freely perform key input through the second key input unit 20 on the customer's side.

In this way, when the second key input unit 20 is set to the locked state, the first key input unit 10 of the clerk side stops using or sets the cooking conditions of the food to be provided to the customer and determines the first operation. The key input unit 10 determines whether a lock key is input or a start key is input (S23) (S24).

That is, the first key input unit 10 may allow the input of the second key input unit 20 by inputting the lock key again. Alternatively, the start key may be input to set cooking conditions and operate the microwave oven.

As such, when the lock key is input from the first key input unit 10 or the start key is input, the key is released through the second key input unit 20 freely by releasing the lock state of the second key input unit 20. To be made (S25).

4 is a flowchart illustrating a control method of a double door microwave oven according to another embodiment of the present invention.

In the present embodiment, the basic state of the second key input unit 20 is in a locked state, and thus free key input is not possible (S31).

In this way, the second key input unit 20 determines whether the lock key is input from the first key input unit 10 in a locked state (S32).

For example, when a customer requests a shop assistant to use a microwave oven, a lock key is input by the first key input unit 10 to allow key input of the second key input unit 20.

When the lock key is input as described above, the locked state of the second key input unit 20 is released to enable the second key input unit 20 to input cooking conditions through key input and display it (S33).

In this way, the first key is used to determine when the second key input unit 20 stops the use of the customer while the customer is freely using the unlocked state or operates after the customer sets the cooking conditions. After the lock key is input from the input unit 10 or the cooking condition is set by the second key input unit 20, it is determined whether a start key for operating the microwave is input (S34) (S35).

That is, the input of the second key input unit 20 may be restricted by inputting the lock key again in the first key input unit 10, and in order to set cooking conditions and operate the microwave oven in the second key input unit 20. You can also complete the keystroke by entering the start key.

As such, when the lock key is input from the first key input unit 10 or the start key is input from the second key input unit 20, the second key input unit 20 is set to a locked state to prevent free key input. (S36).

As described above, in the present invention, when a key input unit is installed at each door side of a double door type microwave oven to operate the microwave oven, when a key input is made through a key input unit on one side, key input is performed on the other side at the same time. It is possible to limit the function of the other key input unit so that it is impossible to prevent the wrong input or malfunction through the key input at the same time has the advantage that the convenience is improved.
