How to input cooking time through encoder of microwave oven

The present invention relates to a cooking time input method for a microwave oven, and more particularly to a cooking time input method through an encoder of a microwave oven.

In general, a block diagram of a hardware for performing a cooking time input process through an encoder of a microwave oven is shown in FIG. 1. The encoder 10, which is used for outputting a pulse by a user's operation and inputting a cooking time, A microcomputer 20 for setting a cooking time by a pulse inputted through the encoder 10 in an internal memory and outputting a control signal for displaying the cooking time on the display unit 30, And a display unit 30 for continuously displaying the cooking time set by receiving the control signal output from the controller 30.

As shown in FIG. 2, a method of inputting a cooking time through an encoder of a microwave oven according to the related art, which is performed through such a hardware, is as follows. First, in step S1, the microcomputer 20 generates a pulse output from the encoder 10 (NO), the CPU repeats the step S1. If the cooking time is input (YES), the CPU 21 proceeds to step S2 to select the microcomputer 20 (NO), the microcomputer 20 jumps to another mode. If the manual cooking mode is selected (YES), the microcomputer 20 proceeds to step S3 to determine whether the microcomputer 20 is in the manual cooking mode 10), it is determined whether or not the set time in the memory is less than one minute. If the set time exceeds one minute (NO), the processing proceeds to step S4.

In step S4, the microcomputer 20 determines whether the time set in the memory by the encoder 10 is less than three minutes. If the set time exceeds three minutes (NO), the microcomputer 20 proceeds to step S5, The controller 20 determines whether the time set in the memory through the encoder 10 is less than 10 minutes. If the set time exceeds 10 minutes (NO), the processing proceeds to step S6.

In step S6, the microcomputer 20 determines whether the time set in the memory is less than 20 minutes by the encoder 10. If the set time exceeds 20 minutes (NO), the microcomputer 20 proceeds to step S7, The microcomputer 20 determines whether or not the time set in the memory by the encoder 10 is less than 40 minutes. If the set time exceeds 40 minutes (NO), the microcomputer 20 proceeds to step S8, 5 minutes, and the process proceeds to step S9.

In step S9, if the microcomputer 20 determines the direction of rotation of the encoder 10 and the microcomputer 20 is in the counterclockwise direction (YES), the microcomputer 20 proceeds to step S10, 10) is decreased by an increment value every time it rotates once, is set in the memory of the microcomputer 20, and then the process proceeds to the step S1.

On the other hand, if the time set in the memory of the microcomputer 20 in step S3 is less than one minute (YES), the microcomputer 20 proceeds to step S11 and the microcomputer 20 sets the increment to 5 seconds, If the time set in the memory of the microcomputer 20 in step S4 is less than three minutes (YES), the microcomputer 20 proceeds to step S12 to set the increment to 10 seconds, If the time set in the memory of the microcomputer 20 in step S5 is less than 10 minutes (YES), the microcomputer 20 proceeds to step S13 and the microcomputer 20 increments the value 30 seconds, and repeats the operations of the step S9 and the following steps.

If the time set in the memory of the microcomputer 20 in step S6 is less than 20 minutes (YES), the microcomputer 20 proceeds to step S14 and the microcomputer 20 sets the increment to 1 minute, If the time set in the memory of the microcomputer 20 in step S7 is less than 40 minutes (YES), the microcomputer 20 proceeds to step S15 to set the increment to 2 minutes The operation of the step S9 and the following steps is repeated.

If the direction of rotation of the encoder 10 is a clockwise direction in step S9, the microcomputer 20 proceeds to step S16 and the microcomputer 20 judges whether the encoder 10 is operated once from the cooking time set in the current memory Is incremented by an increment value each time it is rotated, is set in the memory of the microcomputer 20, and then proceeds to the step S1.

According to the conventional method of inputting the cooking time through the encoder of the microwave oven, if the cooking time for setting in the memory of the microcomputer 20 through the encoder 10 is long, There is a problem that the increase value becomes large and the desired time can not be set accurately.

It is an object of the present invention to provide a method of inputting a cooking time through an encoder of a microwave oven so that an accurate manual cooking time can be set by quickly approaching a desired setting time .

In order to achieve the above object, a method of inputting a cooking time through an encoder of a microwave oven includes a step of inputting a cooking time through an encoder and selecting a manual cooking mode and a step of selecting an interval between cooking times input through the encoder A waiting time determination step of sequentially comparing and determining the waiting time with a set time range; and a waiting time determination step of decreasing the increase / decrease value of the cooking time input through the encoder as the waiting time determined in the waiting time determination step is shorter, And increasing the value of the cooking time as the cooking time becomes longer.
