Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device used in ordinary households.

[0002]

2. Description of the Related Art As shown in FIG. 10, a conventional heating cooker includes a heating chamber 2 for accommodating an object to be heated in a main body 1, a heating chamber 2, a heater 3 attached to the heating chamber 2, and a heating chamber. A temperature sensor 4 for detecting the temperature in the room and a grill 5 for placing an object to be heated are arranged. Outside the main body, a power switch 6, external input means 7 and 8 for starting cooking, and an energization control section for energizing and controlling a heater. 10 and a microcomputer 11.

[0003]

However, in the above-mentioned conventional configuration, when it is desired to perform additional cooking, such as when the cooking color is light, after the cooking is completed, the cooking operation must be started again by pressing the cooking start SW again. It was difficult to get the workmanship he wanted.

[0004]

In order to solve the above-mentioned problems, a first means of the present invention is a second external input means provided separately from a first external input means for starting cooking after cooking is completed. By operating the input means or operating to start cooking, it is possible to re-cook at a regulated temperature lower than the regulated temperature just before the end of cooking by a predetermined temperature. When cooking is desired, additional cooking can be easily performed by operating the second external input means. Further, the second means of the present invention can re-cook at a temperature controlled by a predetermined temperature lower than the temperature controlled immediately before the completion of the cooking by operating the external input means for starting the cooking again after the completion of the cooking. Thus, when it is desired to perform additional cooking at the end of cooking, such as when the baking color is light, the additional cooking can be easily performed by operating the external input means again.

Since the user can re-cook at a lower temperature by a predetermined temperature, the user can adjust the optimum baking color while preventing a rapid change in the baking color even during additional cooking. In addition, since the start of cooking and the start of re-cooking are simultaneously performed by one external input unit, the number of input units is not increased, and the cost can be reduced.

The invention according to claim 7 is the heating cooker according to claim 1, wherein the re-cooking by the external input means can be received only for a predetermined time after the completion of cooking. Is a heating cooker according to claim 7, which has a notifying means for notifying that re-cooking can be accepted by the external input means during a predetermined time. When a long time has passed afterwards, even if the additional cooking is performed as it is, the roasted color is added, but the problem that the temperature inside the object to be heated is low can be prevented.

According to a ninth aspect of the present invention, the re-cooking is automatically terminated after a lapse of a predetermined time from the start of the re-cooking at a predetermined temperature lower than the temperature just before the end of the cooking by a predetermined temperature. The heating cooker according to any one of claims 6 to 8, wherein the additional cooking is automatically terminated, so that even when the user leaves the heating cooker, the additional cooking is performed. It is possible to prevent overcoloring.

According to a tenth aspect of the present invention, the re-cooking can be performed at a regulated temperature lower by a predetermined temperature than the regulated temperature immediately before the completion of the cooking only while the external input means is being operated.
In the heating cooker described above, after cooking is completed, re-cooking can be performed only while operating the external input means, so the user can perform additional cooking while watching the color of the heated object, It can be stopped as soon as the user's favorite brown color is reached.

According to an eleventh aspect of the present invention, the predetermined temperature is set to 5 ° C.
The heating cooker according to any one of claims 1 to 10, wherein the cooking temperature is set to ~ 80 ° C. After the cooking is completed, the user confirms the color of the baked color and feels that the baked color is light and performs additional cooking. When
By re-operating the external input means, it is possible to re-cook at a temperature lower than the regulated temperature of the final step according to each cooking menu by a predetermined temperature. While preventing, the user can adjust the optimal baking color. In addition, since the start of cooking and the start of re-cooking are simultaneously performed by one external input unit, the number of input units is not increased, and the cost can be reduced.
