However, in the configuration of the conventional heating cooker described above, since the light bulb 27 is a point light source, even if it is reflected by the reflection plate 28, the entire cooking object 23 can be illuminated brightly. It was necessary to increase the output. However, in this case, the light bulb 27 is generally large, which causes a problem in terms of storage space. Further, when the output is increased, the life of the light bulb 27 is shortened. Further, since the light bulb 27 is attached to the side wall 22a of the heating chamber 22, there is a drawback that the entire cooked food 23 cannot be illuminated.

Furthermore, in the fermentation cooking, it is necessary to keep the temperature of the heating chamber 22 at a low temperature of 28 ° C. to 35 ° C. for several tens of minutes,
For this reason, the output of the sheet heater 24 having a large wattage is controlled to be low, and heating is performed. However, since the sheet heater 24 and the heating chamber 22 have a large heat capacity, the rise temperature at the start of fermentation is delayed. However, the performance of fermentation cooking was not always satisfactory.

The present invention solves the above problems, and an object of the present invention is to provide a heating cooker capable of instantly illuminating the entire cooking object brightly during cooking, having a long lamp life, and having good fermentation and cooking performance. There is.

[0008]

In order to achieve the above object, a heating cooker according to the present invention comprises a heating chamber for accommodating an object to be cooked and a heater for heating the object to be cooked provided on the ceiling of the heating chamber. And a rod-shaped halogen lamp for irradiating the object to be cooked, a door having a transparent window plate that is openably and closably provided on the front surface of the heating chamber, a temperature detecting means for detecting the temperature of the heating chamber, and A key input unit for performing heating and cooking of an object to be cooked, and a control unit for controlling energization of the heater and the halogen lamp by a signal of the key input unit and the temperature detection means, and the key input unit includes fermentation. A fermentation key for performing cooking is provided, and when the fermentation key is input, the control unit controls the energization of the halogen lamp only for the first fixed time and the fixed time before the end of the fermentation process simultaneously with the input. Constitution Those were.

[0009]

According to the present invention, since the rod-shaped halogen lamp is arranged in the ceiling portion of the heating chamber with the above-mentioned structure, the irradiation width and the light amount (output) can be increased, and the entire cooked material is irradiated by the irradiation from the ceiling. Can be illuminated brighter.

Further, during fermentation cooking, by turning on the halogen lamp for a certain time at the same time as inputting the fermentation key, the heat of the halogen lamp can cover the delay in the rising temperature of the heating chamber, and thus, before the end of the fermentation process. By turning on the halogen lamp again for a certain period of time, you can see the finished state of fermentation cooking from outside.
