The detection result is controlled by the boiler heating means 89 and the pumping means 87.

The 71-series input means shows the operation unit 6 and the display unit 5 here.

The 151 series control means is mounted on the control board 23, and the method of heating and conditioning the food in accordance with the content input by the input means 71 The actor is tested for the state of the food and the state of the heating chamber from each detection means, and then the heating means and the driving means are mobilized as needed.

The LED illumination unit 400 is controlled by the control means 151, and emits light during conditioning to illuminate the inside of the heating chamber 28.

This embodiment is composed of the above-described configuration, and can reduce the temperature rise of the LED, improve the reliability of the life of the LED, and make the wide range of the heating chamber 28 bright so that the state of the food to be processed can be easily visually recognized. During conditioning, the LED illumination unit 400 can be illuminated to illuminate the interior of the heating chamber 28.

Alternatively, the front end portion 506 of the light guiding portion 504 may be a glossy surface, and the diffusing member may be used as a diffuser in a wide range in the heating chamber 28. The diffusing member is made of a transparent member having high heat resistance such as glass, and is blast-processed, dot-printed, or the like on the opposite surface of the heating chamber 28 for obtaining an effect of diffusing light. Processing.

Further, in terms of the diffusing member, a sealing member for performing dielectric printing on, for example, a PET sheet may be used, and it may be adhered to the illuminating portion 28t. The same effect can be obtained.
