2. Description of the Related Art Conventionally, a microwave oven is generally known as a cooking utensil for performing cooking such as thawing, steaming, and baking of food. As a heat source, an electric heater and a molecule of food are vibrated to generate high-temperature frictional heat. Microwaves for generating and heating food are used, and these heat sources are used properly depending on the processing content of the food. Recently, high-temperature hot air has been supplied into the oven of the oven cooker, and saturated steam has been supplied into the high-temperature oven, and the advantages of hot-air cooking such as good baking and steam on the food surface have been improved. There is also known an oven cooker that simultaneously brings out the advantages of steam cooking, such as minimizing the outflow of vitamins, minerals, and delicious ingredients due to the condensation action of the water.

Similarly, recently, foods do not oxidize due to lack of oxygen and have a long shelf life, and as described above, there is little outflow of delicious components due to the condensation of steam on the food surface, and the taste is protected. Because the food is heated by both heat transfer forms of far-infrared radiation and condensation heat transfer, the heat content is large, the temperature inside the food rises quickly, the processing time can be shortened, and the sterilization effect is also excellent, From advantages such as,
Superheated steam has also been used in food processing.

[0005] On the other hand, heating with hot air similarly increases the risk of quality changes such as oxidized browning of foods.
Saturated steam is supplied into the cooking chamber, and even if the temperature rises due to contact with hot air in the cooking chamber, the degree of superheat of the steam is small, and the cooking in the case where the above-described superheated steam is used alone is not effective. Can not realize the advantage. Further, in the cooking chamber, in order to uniform the temperature distribution and suppress uneven grilling, etc., hot air or a mixed gas of hot air and steam is agitated, but these gases are not reused, Since it is exhausted outside the oven cooker, it is not preferable in terms of thermal efficiency, and cannot be said to be an economical treatment method.

The space between the magnesia clinkers forming the heat storage material 23 is solid at room temperature, but is filled with the nitrate which melts and becomes liquid in the temperature range of the superheated steam in this embodiment. Of the heat transfer capability between the respective clinkers and the heat transfer capability to the heat transfer tube 22 due to the presence of the heat transfer tube 22 can be prevented. As a result, it is possible to prevent a decrease in the heat storage speed or the heating speed of the superheated steam to the required temperature, and it is possible to cope with rapid heat storage and rapid heating of the superheated steam.

When the high-temperature heat storage tank 10 cannot be used for repair, steam can be supplied to the cooking cabinet 2 from the auxiliary steam pipe 26a to perform processing such as steaming. Similarly, when the steam generator 13 cannot be used for repair, the steam is passed through the high-temperature heat storage tank 10 from the pipe 26b branched from the auxiliary steam pipe 26a and connected to the inlet side of the high-temperature heat storage tank 10 when the steam generator 13 cannot be used. It can be supplied into the cooking cabinet 2 as superheated steam and subjected to processing such as thawing. Any steam supplied into the cooking cabinet 2 is discharged from an air valve 8 provided at an upper portion of the cooking cabinet 2.
