However, synthetic resins having excellent heat resistance, such as 6-nylon, are expensive, and their color tone is limited, so that a desired color tone or gloss cannot be selected. Therefore, in the conventional case in which the supporting frame 2 is formed of such a synthetic resin, the material cost is high and the supporting frame 2 is expensive, and the color tone and gloss of the supporting frame 2 are limited. The color tone and gloss are also limited due to its balance, and it becomes difficult to make the rice cooker body 1 and the lid 11 into desired designs having various color tones and gloss.

[Function] The heat of the inner frame is conducted to the spacer that is in direct contact with the inner frame. However, since this spacer is made of synthetic resin with excellent heat resistance, it sufficiently withstands the heat and softens or deforms. In addition, the spacer suppresses heat conduction from the inner frame to the support frame, and thus the support frame can be formed of a synthetic resin having low heat resistance. And because the synthetic resin with low heat resistance is cheap, the material cost can be reduced, and the color tone of the synthetic resin with low heat resistance can be selected in a wide range, so the color tone of the support frame can be changed. It is possible to configure a rice cooker with a desired design by selecting various color tones and glosses in consideration of the balance with the main body and lid.

When the rice cooker is used, the user's hand often touches the tubular portion of the support frame or the outer surface of the operating portion, but since the heat conduction from the inner frame to the support frame is suppressed by the spacer, the support frame is provided. Does not become high in temperature, and therefore there is no particular danger even if the user's hand touches the outer surface of the tubular portion or the operating portion of the support frame, and safety is improved. In addition, the load of a heavy pan containing rice and water is applied to the support frame,
Since the temperature rise of the support frame is suppressed and the temperature does not become particularly high, the heat deformation of the support frame is prevented.
