Abstract

A microwave oven and a method of controlling the operation thereof in which an algorithm is provided to operate the microwave oven virtually. The microwave oven comprises a control unit including a microcontroller for storing a program therein, an operating panel including a plurality of keys for inputting key signals regarding various functions of a cooking operation, a display unit for displaying the contents inputted through the operating panel, and a magnetron for generating a microwave under the control of the control unit. The microwave oven further comprises a key select device for selecting a desired one of the plurality of keys on the operating panel to operate the microwave oven virtually, and a simulated operation change device for changing the operation of the microwave oven to a simulated operation in response to the key being selected by the key select device.

Claims

1. A microwave oven comprising:

operating means including a plurality of keys for inputting key signals representing functions of a cooking operation,

key select means for selecting a desired one of said plurality of keys on said operating means to simulate the operation of said microwave oven;

simulated operation change means for changing the operation of said microwave oven to the simulated operation in response to said key being selected by said key select means; and

control means, including a microcontroller, for storing an algorithm to simulate the operation of said microwave oven, wherein during the simulated operation, a magnetron is not operated.

2. A microwave oven as set forth in claim 1, wherein said key select means includes an algorithm, said algorithm being contained in said program.

3. A microwave oven as set forth in claim 1, wherein said simulated operation change means includes an algorithm, said algorithm being contained in said program.

4. A microwave oven as set forth in claim 1, further comprising means for performing the simulated operation of the microwave oven for a simulated operating time, said simulated operating time being less than a set operating time.

5. A microwave oven as set forth in claim 1, further comprising means for releasing the simulated operation of the microwave oven after performing the simulated operation once.

6. A method of controlling the operation of a microwave oven, the method comprising the steps of:

(a) selecting a desired one of a plurality of keys on an operating means to simulate the operation of said microwave oven;

(b) changing the operation of said microwave oven to the simulated operation in response to said key being selected at said step (a) and then simulating the operation of said microwave oven by selectively using said plurality of keys on said operating means;

(c) interrupting the operation of a magnetron during the simulated operation of the microwave oven;

(d) adapting to scale a simulated operating time so that the simulated operating time is less than a set operating time input via the operating means;

(e) decreasing the set operating time when 10 reference clock pulses have elapsed; and

(f) ending the simulated operation when the set operating time is zero.

7. A method of controlling the operation of a microwave oven, as set forth in claim 6, wherein said step (a) includes the step of displaying a simulated operation state on said display means.

8. A method of controlling the operation of a microwave oven, the method comprising the steps of:

(a) selecting a desired one of a plurality of keys on an operating means to simulate the operation of the microwave oven;

(b) changing the operation of the microwave oven to the simulated operation in response to the key being selected in step (a), and then simulating the operation of the microwave oven by selectively using the plurality of keys on the operating means; and

(c) interrupting the operation of a magnetron during the simulated operation of the microwave oven.

9. A method of controlling the operation of a microwave oven, as set forth in claim 8, wherein said step (b) includes the step of performing said simulated operation of said microwave oven for a simulated operating time, said simulated operating time being shorter than an actual operating time.

10. A method of controlling the operation of a microwave oven, as set forth in claim 8, wherein said step (b) includes the step of releasing said simulated operation of said microwave oven after performing said simulated operation once.
