脱溶解を行ってこの高分子膜から離脱する。The gas separation membrane 12 is formed of, for example, cellulose acetate or poly-4-vinylpyridine, and when the pressure reducing device 14 side becomes a low pressure by the operation of the pressure reducing device 14, the air in the inner pot 3 becomes the above. The gas molecules are sucked into the gas separation membrane 12 side through the valve device 11, and the gas molecules of the sucked air are dissolved on the membrane surface of the gas separation membrane 12 on the high pressure side (the valve device 11 side), and then the membrane. Low-pressure side while diffusing between polymer chains inside (the above-mentioned pressure reducing device 14 side)
To the other side of the polymer film, which is the other surface side of the polymer film, and is dissolved on the low-pressure side to separate from the polymer film.

Will be concentrated. For example, since the dissolution rate and diffusion rate of oxygen gas are about 2.5 times higher than those of nitrogen gas, air with a high oxygen concentration can be taken out on the low pressure side of the polymer membrane, and conversely on the high pressure side. There will be air with a high nitrogen concentration.

First, the rice cooker body 1 containing a predetermined amount of rice and water is housed in the rice cooker main body 1, and when an operation unit (not shown) is operated to start rice cooking, a control unit ( (Not shown) controls the energization of the heating element 5 to start the rice cooking operation. At this time, the valve device 11 is switched to the opening 10 side, and the steam generated by boiling the water by the heating of the heating element 5 passes through the intake pipe 9 and is discharged to the outside from the opening 10 via the valve device 11.

The air inside is sucked into the gas separation membrane 12 side through the suction pipe 9 and the valve device 11, and only oxygen in the sucked gas passes by the action of the gas separation membrane 12 and is passed by the decompression device 14. It is discharged from the opening 13 to the outside. Due to the decompression of the decompression device 14, only air with a very low oxygen concentration exists in the inner pot 3, the air pressure is lower than that of the atmosphere, and the yellowing and odor of rice due to heat retention is prevented, and a good heat retention state is obtained. Can be obtained.
