That is, when the energization of the upper and lower heaters 8 and 9 is started in step 146, it is determined whether or not the cooking time Tb has elapsed (step 147). If the cooking time Tb has not elapsed, the selected cooking temperature tx is determined. It is determined whether or not the result of comparison with the current inside temperature th is th ≧ tx (step 14
8) While the in-compartment temperature th is lower than the selected cooking temperature tx and the cooking time Tb has not elapsed, the upper and lower heaters 8 and 9 are kept in the ON state.

If th ≧ tx in step 148,
Stop energizing the upper and lower heaters 8 and 9 (step 14
9) Then, it is determined whether or not the cooking time Tb has elapsed (step 150). If not, whether or not the comparison result of the selected cooking temperature tx and the current in-compartment temperature th is th <tx. Is determined (step 151), and the internal temperature th
Is higher than the selected cooking temperature tx and the cooking time Tb has not elapsed, the upper and lower heaters 8 and 9 are kept in the OFF state, and the inside temperature th is the selected cooking temperature tx within the cooking time Tb.
If it becomes lower than the above, the process returns to step 146.

In step 147, the upper and lower heaters 8,
If it is determined that the cooking time Tb has elapsed while 9 is ON,
The process moves to step 152. In step 152, the energization of the upper and lower heaters 8 and 9 is stopped. Next, after the buzzer 13 notifies that the cooking is completed (step 153), the state is returned to the initial state (step 154).

In step 150, the upper and lower heaters 8,
If it is determined that the cooking time Tb has elapsed during the OFF of 9, the process proceeds to step 153, the cooking end is notified in step 153, and the initial state is returned in step 154.

As described above, in the heating cooker according to the first embodiment, the cooking tray is set in the heating cabinet 2 in the upper and lower two stages and the upper and lower heaters 8 and 9 are energized to start the cooking in the two-stage shelf mode. When a signal is input , the temperature inside the refrigerator at that time
The first cooking time is determined based on the
When the time is over, display a reminder to switch the cooking plates up and down
Then, further, when the door is opened and closed within a predetermined time after the end of the first cooking time, continuous cooking is performed by setting the next cooking time based on the internal temperature immediately after opening and closing the door, It is possible to simultaneously cook two dishes in a quantity corresponding to two dishes using two shelves. That is, when the cookies are cooked using two cooking dishes, the upper cooking dish 4a
The surface of the cookie placed on the lower cooking tray 4b is directly baked by the heating of the upper heater 8, while the cookie placed on the lower cooking dish 4b is baked by the heating of the upper and lower heaters 8 and 9, but the upper cooking dish 4a is heated.
The surface is not directly burned by the heat. Therefore, by exchanging the upper and lower cooking dishes 4a and 4b, the cookies placed on the lower cooking dish 4b can be continuously cooked by the upper heater 8. At this time, the cooking dishes 4a, 4
In order to replace b, the heating control is divided into two parts, but since the preliminary heating is performed the first time, the second cooking time can be shortened, and the control corresponding to the conventional one cooking plate is required. According to the heating cooker of the present embodiment, the cooking time of the second cooking is 40 minutes, while the cooking time of the second embodiment is 30 minutes.
It only took a minute, and it was possible to shorten it by about 10 minutes. Even if the upper and lower cooking dishes are replaced, even if the heating control is performed multiple times, if the user first selects and sets the type of cooking, the second heating is automatically linked with the first heating. It is carried out automatically, so it is easy to use.

Further, the cooking time is calculated from the temperature inside the cooking chamber immediately after the start of cooking or the continuous cooking by using a predetermined calculation formula obtained in advance for each cooking mode. It is possible to accurately set the cooking time according to the above.

Further, since the control device 11A is configured so as not to shift to the continuous automatic operation mode when the door 5 is opened and closed after a lapse of a predetermined time after the end of the first cooking time, the user can set the upper and lower cooking dishes. Forgetting to replace 4a and 4b
There is no confusion when another user uses it after a predetermined time has passed.

Further, the control device 11A is configured so as not to shift to the continuous automatic operation mode if the door 5 is not closed within a predetermined time after the door 5 is opened immediately after the first cooking time ends. Therefore, even if the user forgets to close the door 5 and the person who notices it closes the door 5 after a lapse of a predetermined time or closes the door 5 after the cooked food is taken out, heating is not performed and useless power consumption is performed. Can be avoided.

When a cooking start signal is input from the heaters 8 and 9 for heating the food in the heating chamber and the menu key 7A, the cooking temperature corresponding to the input menu is calculated from the temperature data of various cookings. Cooking temperature selection means 14A for selection and temperature measurement means 15 for measuring the temperature inside the refrigerator
And a temperature difference determining means 16 for determining a temperature difference between the cooking temperature selected by the cooking temperature selecting means 14A and the internal temperature measured by the temperature measuring means 15, and a cooking start signal or a continuous cooking start signal is input. Cooking time calculation means 23 for calculating the cooking time corresponding to the temperature inside the cooking cabinet at this time from the temperature inside the cooking cabinet immediately after the start of cooking or the continuous cooking using a predetermined calculation formula obtained in advance for each cooking mode; When the start signal or the continuous cooking start signal is input and the cooking time signal is input from the cooking time calculation means 23, the cooking temperature selection means 14A selects the temperature difference signal while watching the temperature difference signal input from the temperature difference determination means 16. The heater is turned on and off to keep the inside temperature at the set cooking temperature, and a cooking end signal is output when the cooking time is over. The control means 21A, the door open / close determining means 24 that determines whether the door 5 of the heating cabinet 2 is open or closed, and outputs a signal for opening or closing the door in accordance with the determination result, and the cooking start signal is in the shelf two-stage use mode. In some cases, when the cooking end signal is input and the door open / close determination means 24 inputs the door open signal and the door close signal within a predetermined time after the end of cooking, it is determined to be continuous operation and a continuous cooking start signal is output. Since it is constituted by the continuous operation judging means 25, the accurate cooking time can be set according to the season and the type of cooking.

When the door open signal and the door close signal are input to the continuous operation determining means 25 after a predetermined time has elapsed after the cooking end signal is input, the continuous operation determining means 25 does not output. , When another user uses it after a predetermined time has passed, there is no confusion.

In addition, when the door open signal is input to the continuous operation determination means 25 within a predetermined time after the cooking end signal is input, and the door close signal is not input even after a predetermined time elapses, continuous operation is performed. Since the determination means 25 is configured so as not to output, even if the user forgets to close the door 5 and the person who notices closes the door 5 after a lapse of a predetermined time or closes the door 5 after the food is cooked, the heating is not performed. It is possible to avoid wasting power and avoiding unnecessary power consumption.

When the timer 19 is driven in step 229, it is determined whether or not the notification time Tx has elapsed (step 230). If not, it is determined whether the door 5 has been opened (step 231). . This door open judgment,
The notification time Tx continues until the door 5 is opened.

Without opening the door 5, step 23
If it is determined that the notification time Tx has elapsed at 0, the state is returned to the initial state (step 232).

If it is determined in step 231 that the door 5 is opened during the notification time Tx, the buzzer 13 is stopped (step 233), and then the up / down display of the cooking dishes 4a, 4b is finished. (Step 234), the timer 19 is reset once (step 235), and then the timer 19 is driven again (step 236).

When the timer 19 is driven in step 236, it is determined whether the door opening time Ty (for example, 60 minutes) has elapsed (step 237). If not, it is determined whether the door 5 has been closed. A determination is made (step 238).
This door closing determination is made during the door opening time Ty (60 minutes),
Continue until the door 5 is closed.

Step 2 without closing the door 5
If it is determined in 37 that the door opening time Ty (60 minutes) has elapsed, the state is returned to the initial state (step 239).

If it is determined in step 238 that the door 5 is closed during the door opening time Ty, it is determined that the operation is continuous (step 240) and the timer 19 is reset (step 241). Next, the temperature measuring means 15 measures the current temperature th (for example, 50 ° C.) in the heating chamber 2 based on the detection signal of the temperature sensor 10 2 seconds after the closing door (step 242), and the temperature difference determining means 16 Compares and determines the selected cooking temperature tx (150 ° C.) that has already been set with the current in-compartment temperature th (50 ° C.).

Further, the cooking time selecting means 18A uses the cooking time corresponding to the current inside temperature th (50 ° C.), that is, the Tb time (14 minutes) when 50 ≦ T <100 as the reference of the storing means 17A. It is selected from the cooking time table (FIG. 9) (step 243).

In the heating control means 21B, when the second cooking time Tb (14 minutes) in the continuous cooking is selected, the timer 19 is driven (step 244) and the display section 12 displays the second cooking time Tb (14). Minute) is displayed (Step 2
45), the energization of the upper and lower heaters 8 and 9 is started (step 246), and the internal temperature th is maintained at the set cooking temperature tx (150 ° C.) until the cooking time Tb (14 minutes) elapses. Thus, the upper and lower heaters 8 and 9 are ON / OFF controlled as in steps 246 to 251.

In step 247, the upper and lower heaters 8,
If it is determined that the cooking time Tb has elapsed while 9 is ON,
The process moves to step 252. In step 252, the energization of the upper and lower heaters 8 and 9 is stopped. Then, after the buzzer 13 notifies that the cooking is completed (step 253), the state is returned to the initial state (step 254).

In step 250, the upper and lower heaters 8,
If it is determined that the cooking time Tb has elapsed during the OFF of 9, the process proceeds to step 253, the cooking end is notified in step 253, and the initial state is returned in step 254.

Also in the heating cooker according to the second embodiment, the cooking start signal in the two-stage shelf use mode in which the cooking plates are set in the heating cabinet 2 in the upper and lower two stages and the upper and lower heaters 8 and 9 are energized.
