Usually, ABS resin or polypropylene resin is used for the lid (10) of this type. Then, as shown in the figure, a lid heater (25) and a reflection plate (20) are attached to the lower surface of the lid body (10). A latch (13) is fixed to the tip, and a hinge shaft (14) bearing or the like is provided at the other end. The bearing of the hinge shaft (14) serves as a rotation fulcrum when the lid (10) is opened and closed. Further, the latch (13) and the hinge shaft (14) support the weight of the main body (1) when carrying the rice cooker by holding the handle (11).

[Problems to be Solved by the Invention] As described above, the lid heater (25) and the reflection plate (20) are attached to the inner surface of the lid body (10) of the conventional rice cooker so as to be exposed in the heating space. . For this reason, not only does the steam containing starch that is generated during rice cooking adhere to the reflection plate and stop reflecting heat, but the starch that contains water becomes a heat medium and becomes the direction of the lid (10). Heat will be transferred to. As a result,
There is a risk that the heat efficiency will decrease and that the lid (10) will be deformed by heat. Further, since the lid heater (25) is attached to the front surface of the reflection plate (20), the reflection plate (20) is soiled.
It's inconvenient because it gets in the way of cleaning. In particular, when the lid heater (25) with large power is provided, such a decrease in reflectance and the deformation of the lid body (10) are further promoted. Once the lid body (10) is deformed, a gap is formed between the lid body (10) and the body (1), heat and steam escape through the gap, wasting power, and significantly lowering rice cooking performance. In particular, when the lid (10) is provided with an operating portion, there is a problem that the circuit element is affected by heat and malfunctions occur.

[Operation] A heat insulating material is fitted in the concave portion provided in the reflection plate, and is interposed from above. Further, the concave portion of the reflecting plate that projects downward is further fitted into the hollow portion of the support frame. Further, the lead wire of the lid heater is led out from the gap between the cutout portion of the support frame and the reflection plate. Then, the heat projected upward from the lid heater is reflected by the reflection plate and further blocked by the heat insulating material, and most of the heat is projected toward the inner pot.
