  Next, the specific configuration will be described.

  An inner pot 2 is detachably inserted into the main body 1, and a lid 3 covering the upper surface opening of the main body 1 and the inner pot 2 is provided on the upper surface of the main body 1 so as to be freely opened and closed. The lid 3 is provided with a seal packing 4 which is in close contact with the upper end flange portion of the inner pot 2 and a steam port 5 which is the only passage connecting the space inside the inner pot 2 closed by the seal packing 4 and the outside.

  The heating means 6 is provided in the lower part in the main body 1, and the site | part of the inner pot 2 facing this is induction-heated.

  A container 7 is detachably stored in the inner pot 2. The container 7 is made of ceramic (pottery), and a plurality of convex portions 8 are provided at the bottom portion and the top flange portion toward the inner surface of the inner pot 2 at substantially equal intervals. The inner pot 2 and the container 7 are convex. The portions 8 are in contact with each other, and the portions other than the convex portions 8 are held so that a space is formed between the bottom portion and the side portion. In the upper part of the inner pot 2 and the container 7, a plurality of openings 9 formed by this space are formed all around.

  A bottom temperature sensor 10 that detects the temperature of the bottom of the inner pot 2 is provided at the lower part of the main body 1, and an infrared sensor 11 that detects the temperature inside the inner pot 2 is provided at the lid 3.

  On the front surface of the main body 1 is provided an operation unit 12 having a selection means 14 including a normal rice cooking button 14a and a steam rice cooking / steaming cooking button 14b, and a start button 14c. In response to this, the control unit 13 controls the heating of the heating means 6 on the basis of the temperature information of the bottom temperature sensor 10 and the infrared sensor 11 and automatically adjusts the heating.

  The container 7 is detachably covered with a container lid 15.

  Next, an actual use procedure will be described.

  First, the usage method of FIG. 3 is demonstrated. This puts rice and water directly into the inner pot 2 without using the container 7. Next, a normal rice cooking course is selected by the selection means 14 of the control unit 13, and the normal rice cooking button 14a and the start button 14c are operated to start heating. Thereby, the inner pot 2 is heated by the heating means 6.

  Since the subsequent state is the same as that of a general rice cooker, detailed description is omitted, but the control unit 13 performs heating and cooking necessary for rice cooking based on the temperature information of the bottom temperature sensor 10, and rice cooking is performed.

  Next, the usage method of FIG. 1 is demonstrated. The user puts an appropriate amount of water in the inner pot 2 in advance. Thereafter, an appropriate amount of rice and water is put into the container 7, and the container 7 is put into the inner pot 2 without the container lid 15.

  Since a plurality of convex portions 8 are provided on the bottom portion and the upper end flange portion of the container 7, the container 7 is fixed in a state where there is a space in the inner pot 2. Since this space is connected to the space closed by the inner pot 2 and the seal packing 4 through the opening 9 at the upper end, water exists in the space between the inner pot 2 and the container 7.

  Next, the lid 3 is closed, the steam cooking course is selected by the selection means 14 of the operation unit 12, and the steam cooking button 14b and the start button 14c are operated to start heating.
