The storage element used in the storage unit 15 is preferably a storage element such as a non-volatile memory that does not lose its memory even when the power is turned off.

Next, the operation of this heating cooker will be described with reference to the flow charts of FIGS. First,
When performing "heater / high frequency automatic cooking" by one-key operation, the heater / high frequency automatic cooking start key 12a of the operation unit 11 is pressed (step S21 in FIG. 6). When the heater / high-frequency automatic cooking start key 12a is pressed, the tray position sensor 9 detects whether the tray 8 is installed in the heating chamber 1 (S22), and if detected, the weight sensor 6 is detected.
Whether the turntable 4 is installed is detected by (S23). When the turntable 4 is also detected, it means that both the tray 8 and the turntable 4 are installed in the heating cabinet 1, and misuse of the heating cooker is indicated by the display section of the operation section 11 and the buzzer. Notify the user (S24, 25). Further, when the turntable 4 is not detected (S23), since only the tray 8 is installed in the heating chamber 1, the heater 2 is selected by the heating source selection means 13 and the heating and cooking of the heater is started. (S26).

At this time, the cooking temperature and the like differ depending on the installation position of the tray 8 detected by the tray position sensor 9,
For example, when the tray 8 is installed on the upper receiving rack 7, the heater 2 on the ceiling of the heating cabinet 1 is fully used to make the surface of the object to be heated in the tray 8 brown and the cooking (the cooking temperature is About 300 ° C, cooking time is about 15 to 30 minutes), and when it is installed in the middle shelf 7, for example, oven cooking to bake relatively short confectioneries such as cookies and roll cakes (cooking temperature is 180 ℃, cooking time is 15 ~ 20
When installed in the lower shelf 7, for example, oven cooking for baking relatively tall confectionery such as sponge cake (cooking temperature is about 170 ° C., cooking time is 35 to 45
Minutes). In any case, the control unit 16 sets the cooking time based on the detection signal of the temperature sensor 10 or the like, and when this cooking time elapses (S28), the heater heating cooking of the object to be heated in the tray 8 is finished ( S34).

On the other hand, the tray 8 is detected by the tray position sensor 9.
If is not detected (S22), the weight sensor 6 detects whether the turntable 4 is installed (S29). When the turntable 4 is not detected, it means that both the tray 8 and the turntable 4 are not installed in the heating cabinet 1, so that the misuse of the heating cooker is indicated by the display section of the operation section 11 and the buzzer. To inform the user (S24, 25). Further, when the turntable 4 is detected (S29), since only the turntable 4 is installed in the heating chamber 1, the magnetron 3 is selected by the heating source selection means 13 and the high frequency heating cooking is started. (S30). Then, the weight of the object to be heated or the like is calculated based on the total weight detected by the weight sensor 6 (S31, 32). At this time, since the calculated value is the weight of the object to be heated and the container in which the object to be heated is stored,
This value is the maximum cooking time, and the normal cooking time is 1
The cooking time is set based on a detection signal from a gas sensor (not shown) that detects vapor emitted from the object to be heated provided on the side wall or the like of S (S33). Then, when the cooking time elapses (S28), the high frequency heating cooking of the object to be heated placed on the turntable 4 ends (S34).

Next, for example, when a material to be heated such as hamburger's material is housed in a frying pan 5, the surface of the frying pan is directly burned with a gas, and then high frequency cooking is carried out. Press the high frequency exclusive cooking start key 12b of the operation unit 11 (step S in FIG. 7).
41). When the high frequency exclusive cooking start key 12b is pressed, the weight sensor 6 detects whether the turntable 4 is installed in the heating chamber 1 (S42), and if detected, the frying pan 5 is installed on the turntable 4. It is detected whether it is done (S43). Then, when the frying pan 5 is detected, high-frequency cooking by the magnetron 3 is started (S44), and at the same time, the weight of the object to be heated on the frying pan 5 is calculated based on the total weight detected by the weight sensor 6 (S45, 46), and the cooking time corresponding to the calculated value is set (S47). When the cooking time elapses, the high frequency cooking of the object to be heated on the frying pan 5 ends (S48, 49).

When the turntable 4 is not detected (S42) or when the frying pan 5 is not detected (S43), it means that the cooking device is misused and the display section of the operation section 11 and the buzzer indicate that the user is using the cooking apparatus. (S50, 51).

Next, when "preheating" is performed, the heater-dedicated heating start key 12c of the operation unit 11 is pressed (step S61 in FIG. 8). When the heater-dedicated heating start key 12c is pressed, the tray position sensor 9 detects whether the tray 8 is installed in the heating chamber 1 (S62), and if not detected, the weight sensor 6 installs the turntable 4. It is detected whether it is done (S65). And
When the turntable 4 is not detected, both the tray 8 and the turntable 4 are not installed in the heating chamber 1, and heating (preheating) in the heating chamber 1 by the heater 2 is started (S66). . Next, the preheating time is set based on the preset preheating temperature and the detection signal from the temperature sensor 10 (S67), and when the preheating time elapses, the preheating of the heating chamber 1 is finished (S68, 69).

When the tray 8 is detected (S6
2) or when the turntable 4 is detected (S6
In 5), the cooking device is misused, and the user is informed by the display of the operation unit 11 and the buzzer (S63,
64).
