Since the heating element 2112 is provided below the plate body 2111, the steam 93 passing through the space 96 can be reheated to raise the temperature of the steam. On the other hand, since the steam generated in the heating zone 2102 cannot pass directly through the cover 2113, the humidity in the food containing portion 20 can be controlled. The apparatus of the present invention has the following advantages: 1. The unit molecular density is lowered, so that in the food material accommodating portion 20, almost no vapor is observed. This can reduce the humidity in the food containing portion 20. 12 200936086 2. Molecules are more active and more penetrating, thus reducing input power. 3. The convection effect is good. The temperature difference between the upper and lower parts of the food receiving part 20 is small, about 2 degrees, and the conventional device is nearly ten degrees. 4. The steam temperature is high, and it is not easy to condense into dew in the box (food material 90 and shelf 201), and most of them condense in the place where the heat dissipation is quick, such as the surrounding partition plate 202, so that the humidity in the food material accommodating portion 20 is lowered, and the life of the food material is prolonged. 5. After the temperature is stopped and the heating is stopped, the residual heat of the cover 2113 continues to be baked in the case, further reducing the humidity in the food containing portion 20. However, the above is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. It is to be understood that the scope of the present invention is not limited by the spirit and scope of the present invention, and should be considered as a further embodiment of the present invention.
