An inner pot 4 is housed in the inner frame 2 so as to be freely put in and taken out. The inner pot 4 is supported by placing its upper opening edge on the upper opening edge of the inner frame 2, and in the supported state, the outer surface of the bottom wall is placed close to directly above the rice cooking heater 3. It has become.

A control section 5 is attached to the rice cooker main body 1 at a position below the inner frame 2 thereof. The control unit 5 controls the rice cooking heater 3 and the like according to a specified rice cooking menu.
These control unit 5 and rice cooking heater 3 are connected in parallel to a commercial AC power source as shown in FIG.

A receiving section 6 is provided in a part of the control section 5, as shown in FIGS. 1 and 2. The receiving section 6 receives an operation command signal from a transmitting section, which will be described later. This receiving part 6 is located near the outer side of the outer surface of the peripheral wall of the inner frame 2 (see Fig. 2), and a through hole (not shown) is provided in the upper part of the rice cooker main body 1 facing above the receiving part 6. It is provided.

A lid 8 is rotatably attached to the rice cooker main body 1 via a hinge 7 (see FIG. 4). The lid 8 is rotated around the hinge axis of the hinge 7, so that the rice cooker main body 1
It opens and closes the top opening, and an inner lid (not shown) that closes the top opening of the inner pot 4 is detachably attached to its inner surface. Of course, this lid 8 is equipped with a pressure valve 9.
