In FIG. 2, an upper heater 7 and a lower heater 8 provided on the upper surface of the caning 10 constituting the apparatus main body described above are connected to a power source 13 via a switch 11 and a door switch 12.

The switch 11 is a regular contact, and is opened/closed in response to a control signal output from the control unit 14, and is configured to connect/disconnect the driving force supplied from the power source 13 through the door switch 12.

The control unit 14 includes an arithmetic processing unit equipped with an internal timer, a storage unit, an input/output unit, and the like.

When the heating period N and the residual heat heating time are manually set by the operation unit 2, the arithmetic processing unit closes the switch 11 to drive the upper heater 7 and the lower heater 8 based on the manually set heating time. At the same time, when the manually set preheating time has elapsed, the buzzer 15 is activated.

When only the heating time is manually specified by the operation unit 2, the arithmetic processing unit stops driving the upper heater 7 and the lower heater 8 and activates the buzzer 15 when the heating time has elapsed.

On the other hand, when the automatic cooking mode is set by the operation unit 2, the arithmetic processing unit also processes the heater heating time data and residual heat heating data set according to the type of food to be cooked stored in the storage unit. Based on the time data (shown in FIG. 3), the heater heating time set by the time setting key 1b and the subsequent preheat heating time are automatically set. The buzzer 15 is activated after the set preheating time has elapsed (when the preheating time is 0, after the heater heating time has elapsed).

In the control mode described above, the residual heat heating time T2 (as mentioned above, it may be O) by cutting off the heater current shown in FIG. This is the heater energization time set by the operator.

)0 Next, in the place where mochi is baked using the heating cooking device according to this example,
The control operation when the mode in which the preheat heating time is automatically set will be explained with reference to the flowchart shown in FIG. 5.

The cook places the mochi 9 inside the device body as shown in Figure 6(a).
After setting, when the door is closed, the door switch 12 is also closed accordingly. Next, the cook presses the rice cake key 5e of the automatic cooking selection key section 5 to t″f:, and by operating this rice cake key 5e, a signal is sent from the automatic cooking selection key section 5 indicating that the rice cake key 5e has been operated. Upon recognizing that has been output (step 21), the arithmetic processing unit:
λ1 for mochiyaki from the data stored in the storage unit.
The corresponding preheat heating time data (2 minutes) is read out (step 22). After reading the heater heating time data and residual heat heating time data for mochi baking from the storage section in step 22, when it is recognized that the cooking start key 3f has been operated (step 23), the process moves to step 24. . That is,. By closing the switch 11, the upper heater 7
, the lower heater 8 is driven, and both the upper and lower heaters are used to perform the rice cake roasting process (step 24). Upper heater 7 and lower heater 8
The mochi 9, which is heated from both the upper and lower directions, expands as shown in FIG. 6(b) due to these heatings. In step 24, the upper heater 7 and the lower heater 8 are driven, and the heater heating indicator 4
a is turned on (step 25). In this way, the upper heater 7 and the lower heater 8 are driven, and the heater heating indicator 4a is turned on, and the cooking stop key 6 is pressed in the middle of the process.
Unless a signal is given from the operation unit 2 indicating that the heater has been heated (step 26), both the upper and lower lids and the heater heating indicator 4a continue to be driven until the heater heating time read out in step 22 has elapsed. . When it is recognized from the output from the internal timer that the heater heating time set in step 22 has elapsed (step 27), driving of both the upper and lower heaters is stopped by opening the switch 11 (step 28), and the heater heating is stopped. The indicator 4a is turned on (step 2), and the residual heat heating indicator 4b is turned on (step 30).

When it is recognized from the output from the internal timer that the preheat heating time read in step 22 has elapsed (step 31), the preheat heating indicator 4b turned on in step 30 is turned off (step 32), and the buzzer 15 is turned off. The cook is notified of the completion of cooking by outputting a drive command signal to (step 33).

At the time of step 33, the rice cake 9 is heated by its own residual heat and the residual heat in the internal space defined by the casing 10, and is in a moderately cooked state as shown in FIG. 6(e). It becomes.

When the cook visually checks the cooking status of the mochi 9 in the device main body and operates the cooking stop key 2b thinking that he wants to stop the rice cake cooking midway through, the cooking stop key 2b is operated from the operating section 2. A signal indicating this is output to the control section 14. When the arithmetic processing unit recognizes that the above-mentioned signal has been output from the operation unit 2 (step 26), it immediately moves to step 28, performs the processing operations shown in steps 29 and 30, and then performs the residual heat heating after step 31. This will lead to a transition to the following flow. In this case, if the object to be cooked is toast or pizza whose preheating time is O, the process immediately proceeds to step 33 without going through steps 31 and 32, and the buzzer 15 is activated.

When any of the keys other than the above-mentioned rice cake key 5e, for example, the toast key 5b, the visa key 5e, or the gratin key 5d, is operated (step 21, step 34), the process moves to step 35, and if, for example, the gratin key 5d is operated, Set the heater heating time required for gratin cooking and the special residual heat heating time (3 minutes, see Figure 3) stored in the memory unit in the internal timer, and set the flow of mochi baking and 1.
1st. Execute gratin cooking with a simple process! (Step 35). Even when toast key 5b or visa key 5C is operated, the residual heat heating time is 0.
The same as above except that .

In steps 21 and 34, none of the keys provided in the automatic cooking selection key section 5 are operated,
When each of the keys 3a to 3d of the operation key section 3 is operated and the time setting key 1b is operated, the arithmetic processing section does not perform automatic cooking based on the data stored in the storage section, but performs heater heating 11!1. Various types of cooking will be executed in a mode in which the preheating time and residual heat heating time are manually set. In this way, even in the mode in which the heater heating time etc. are manually set, first the three time setting keys 1b are operated, then the preheat heating time setting key 3d is operated and the time setting key 1b is operated. When operated, both keys 3 above
After the preheating time set by d and lb has elapsed, the buzzer 15 is activated. Also, if the preheating time is not set as described above, the buzzer 1 will be activated after the manually set heater heating time has elapsed.
5 will be started.

As explained above, according to an embodiment according to the present invention, by variably adjusting the output of the heater, the surface of the rice cake 9 can be prevented from being overly scorched without adversely affecting the toast cooking. The inside of the can be baked to a sufficiently soft state. Therefore, once baked rice cakes are eaten with seasonings added to them, the inside is hard, so there is no need to reheat the rice cakes, and there is no need to contaminate the inside of the device with seasonings. Also, grilled mochi. Not only for E-cooking, but also for gratin cooking that requires preheating.
The same effect as above can be obtained.

In this embodiment, a heating cooking device with a built-in microcomputer and an automatic cooking function has been described, but the present invention is not only applicable to heating cooking devices with a built-in microcomputer, but also Naturally, the present invention can also be applied to a heating cooking device that only has a manual cooking function in which the residual heat heating time is set using a manual timer or the like provided in the operating section.

〔Effect of the invention〕

As explained above, according to the present invention, when the preheating time is set by the preheating time setting means, the preheating time is set by the preheating time setting means, rather than when the driving time of the heating means set by the driving time setting means has elapsed. Since it is activated when it detects that the preheating time has elapsed to notify that cooking has finished, the output of the heating means can be variably adjusted to ensure high-quality toast without adversely affecting toast cooking. It is possible to provide a conditioning cooking device that can perform 1-stroke cooking.

It is an explanatory view of the operation concerning the heating cooking device according to the example.
