Next, the operation of the present embodiment will be described with reference to flowcharts of the cooking selection program shown in FIGS. 4 to 6 and FIGS. 7 to 10. First, when the power is turned on, the control circuit 32 starts (starts) the cooking selection program according to the flowchart shown in FIG. After executing the initialization processing in step S1, the control circuit 32 repeats steps S2 and S3 to enter a standby state until the operation dial 20 is pressed with the door 16 closed. In this standby state, the menu display section 19 is in a state where no display characters are displayed.

When the user presses the operation dial 20 once after housing the object to be heated in the cooking chamber 12 and closing the door 16, the control circuit 32 causes the dial switch 2 to operate.
Since a pressing operation signal is provided from the input circuit 26 through the input circuit 26a, "YES" is determined in the step S3, and the process proceeds to a step S4. The control circuit 32 outputs a display signal to the backlight 23 to display that the automatic heating mode is selected in step S4, and displays the automatic display section 21a of the automatic heating menu display section 21. At the same time, the title of each automatic heating menu group is displayed.

Subsequently, the control circuit 32 proceeds to step S5, outputs a display signal to the indicator LED 27,

In this state, the control circuit 32 determines in step S
It is in a state of accepting the turning operation and the pressing operation of the operation dial 20 while passing through 10 and S11. If neither operation is performed, these operations are repeated through steps S8 and S9, and if the pressing operation is performed, the process returns to step S4. Has become. Accordingly, in the program after step S3, the control circuit 32 sets the display state of the automatic heating mode (see FIG. 7A) when only the pressing operation of the operation dial 20 is performed an odd number of times, and performs the even number of times. When the manual cooking mode is displayed (see FIG. 7).
(B)).

Next, when the operation dial 20 is rotated in the display state of the automatic heating mode, that is, when "YES" is determined in the step S6, the control circuit 32 shows in the flowchart of FIG. The process proceeds to step S12 to execute the operation of selecting the automatic heating mode. In step S12, the control circuit 32 performs the operation of displaying the automatic heating menu according to the amount of rotation of the operation dial 20.

That is, when the operation dial 20 is turned, the number of pulse signals corresponding to the amount of rotation is input from the dial encoder 25 to the control circuit 32 via the input circuit 25a. The control circuit 32 controls the backlight 23 and the display unit LED2 based on the pulse signal.

The automatic heating cooking is executed by controlling the driving of the heater 14 and the like according to a heating cooking program (not shown).

Next, when the operation dial 20 is rotated in the display state of the manual heating cooking mode, that is, when "YES" is determined in the step S10, the control circuit 32 shows in the flowchart of FIG. Step S18
Then, the operation of selecting the manual heating mode is performed. The control circuit 32 performs a display operation of the manual heating mode in accordance with the amount of rotation of the operation dial 20 in step S18.

In other words, when the operation dial 20 is turned, the control circuit 32 receives a pulse signal of a number corresponding to the amount of rotation from the dial encoder 25 via the input circuit 25a. The backlight 23 in the manual heating mode in the order in which the backlight 23 is turned on is displayed (FIG.
(See (a) and (b)). Subsequently, the control circuit 32 waits for an operation input of either the pressing operation or the turning operation of the operation dial 20 while repeating steps S19 and S20.

Here, for example, when the operation dial 20 is turned, the control circuit 32 determines "Y" in step S20.
ES ”, the process returns to step S18, and the manual heating / cooking mode is displayed again in the order corresponding to the amount of rotation of the operation dial 20, and the change is accepted. When the operation dial 20 is pressed, the control circuit 32 determines “YES” in step S19 and shifts to step S21 to determine whether the currently displayed manual heating mode is “oven”. Judge. Therefore, when the oven heating cooking is selected and displayed, the control circuit 3
2 is “YES” in the step S21, and the step S21 is performed.
When the process proceeds to step S22 and another cooking mode is selected and displayed, the process jumps to step S28 as described later.

First, when the oven cooking mode is selected, the control circuit 32 outputs a display signal to the indicator LED 27 and blinks the "temperature" of the operation indicator 29 in step S22. As a result, the next operation procedure for the user is displayed to prompt the user to rotate the operation dial 20 to input the set temperature of the oven. Then, the control circuit 32
Is in a standby state in which step S23 is repeated until the operation dial 20 is rotated.

When the operation dial 20 is turned, the control circuit 32 proceeds to step S24, where the digital display unit 18 is controlled based on a pulse signal corresponding to the amount of rotation.
A display signal is output to display the temperature (see FIG. 10A). Subsequently, the control circuit 32 is in a standby state in which steps S25 and S26 are repeated until the operation dial 20 is pressed or rotated. During this time, when the operation dial 20 is turned again, the control circuit 3
2 judges "YES" in step S26, returns to step S24, and displays a temperature corresponding to the rotation amount.

Thereafter, when the operation dial 20 is pressed, the control circuit 32 returns "Y" in step S25.
ES ”, the process proceeds to step S27, and the displayed temperature is read and set as the heating cooking condition.
Proceed to step S28. The control circuit 32 outputs a display signal to the indicator LED 27 to
"Time" flashes. As a result, the next operation procedure for the user is displayed to prompt the user to rotate the operation dial 20 to input the cooking time (FIG. 10 (b) showing the case of "high range").
reference). Then, the control circuit 32 is in a standby state in which step S29 is repeated until the operation dial 20 is rotated thereafter. It should be noted that, in the above-described step S21, “YE
S ”, that is, in the case of the manual cooking mode other than the“ oven ”mode, the control circuit 32
Jumping to step S28, the following steps are executed in the same manner.

When the operation dial 20 is turned, the control circuit 32 proceeds to step S30, where the digital display unit 18 is controlled based on a pulse signal corresponding to the amount of rotation.
The display signal is output to display the cooking time. Subsequently, the control circuit 32 proceeds to step S31, outputs a display signal to the indicator LED 27, blinks the start indicator 28, and completes the setting of the cooking conditions and can start heating cooking. This is displayed (see FIG. 10C showing the case of “high range”).

In this state, the control circuit 32 repeats steps S32, S33, and S31 to receive the start of the heating cooking by the pressing operation of the operation dial 20 and to input the change of the cooking time by the rotating operation. Will accept. When the operation dial 20 is rotated, the control circuit 32 accepts the operation and returns to step S30 to again increase or decrease the time according to the amount of rotation, and thereafter, the operation dial 20 is pressed. Then, “YES” is determined in the step S32, and the process shifts to a step S34.

The control circuit 32 reads and sets the cooking time displayed on the digital display section 18, and then proceeds to step S3.
Then, the process proceeds to step S5, and the manual heating cooking is executed under the cooking conditions set as described above by the heating cooking program corresponding to the selected manual heating cooking mode.
