Note that it is desirable to use a storage element such as a non-volatile memory that does not lose its memory even when the power is turned off, as the storage element used for the storage unit 15.

Next, the operation of the cooking device will be described with reference to the flowcharts of FIGS. First,
When "heater / high-frequency automatic cooking" is performed 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 or not the tray 8 is installed in the heating chamber 1 (S22).
It is detected whether or not the turntable 4 is installed (S23). When the turntable 4 is also detected, both the tray 8 and the turntable 4 are set in the heating chamber 1, and the misuse of the cooking device is indicated by the display unit of the operation unit 11 and the buzzer. The user is notified (S24, S25). 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 selecting means 13, and the heater heating cooking 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 shelf 7, the heater 2 on the ceiling of the heating cabinet 1 is fully used, and the surface of the object to be heated in the tray 8 is browned. Oven cooking (at a cooking temperature of 180 ° C.) for baking relatively short confections such as cookies and roll cakes when installed in the middle receiving shelf 7 is performed at about 300 ° C. and the cooking time is about 15 to 30 minutes. ℃, cooking time is 15-20
Minutes), when placed in the lower receiving shelf 7, oven cooking for baking relatively tall confectionery or the like such as sponge cake (cooking temperature is about 170 ° C., cooking time is 35-45).
Minutes). In any case, the control unit 16 sets a cooking time based on the detection signal of the temperature sensor 10 and the like, and when this cooking time has elapsed (S28), the heater heating cooking of the object to be heated in the tray 8 ends (S28). S34).

On the other hand, the tray 8 is detected by the tray position sensor 9.
Is not detected (S22), the weight sensor 6 detects whether the turntable 4 is installed (S29). If the turntable 4 is not detected, it means that both the tray 8 and the turntable 4 are not installed in the heating chamber 1 and the misuse of the cooking device is indicated by the display unit of the operation unit 11 and the buzzer. To inform the user (S24, S25). 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 selecting means 13, and high-frequency heating cooking is started. (S30). Next, 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
The cooking time is set based on a detection signal from a gas sensor (not shown) for detecting steam emitted from the object to be heated, which is provided on the side wall or the like (S33). Then, when the cooking time has elapsed (S28), the high-frequency heating cooking of the object to be heated placed on the turntable 4 ends (S34).

Next, for example, when an object to be heated such as a hamburger material is accommodated in a frying pan 5 and the surface is browned directly by direct gas fire, high-frequency heating cooking is performed. Press the high-frequency heating cooking start key 12b of the operation unit 11 (step S in FIG. 7).
41). When the high frequency 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 it is detected, the frying pan 5 is installed on the turntable 4. Is detected (S43). When the frying pan 5 is detected, high-frequency heating 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), a cooking time corresponding to the calculated value is set (S47). When the cooking time elapses, the high-frequency heating 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), the cooking device is misused, and the display unit and the buzzer of the operation unit 11 are used by the user. (S50, 51).

Next, when performing "preheating", 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, the weight sensor 6 installs the turntable 4. It is detected whether the operation has been performed (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 the heating (preheating) of the heating chamber 1 by the heater 2 is started (S66). . Next, a preheating time is set based on a preset preheating temperature and a detection signal from the temperature sensor 10 (S67), and after this preheating time has elapsed, the preheating of the heating chamber 1 ends (S68, 69).

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

[0012]

The conventional heating cooker as described above has a heater / high-frequency automatic cooking start key 12.
The operation key 12a is frequently used because it is convenient because all cooking of "heater / high-frequency automatic cooking" can be automatically performed by one key operation of "a".
