It is to provide a rice cooker that can prevent it from hanging on the ring . In order to achieve the above object, in the present invention, in the present invention, an outer frame that constitutes the outer shell of the main body, and the upper end surface of this outer frame. It is equipped with an upper frame that composes the main body, an inner frame that is installed in the main body, a hook that is installed in the inner frame, and a lid that covers the opening of the upper surface of the hook. A hinge receiving portion formed on the inner surface of the lid and outside the upper frame.
It is characterized in that it is provided with a spring that is placed and supported to give an opening force to the lid. According to the above means, since the hinge receiving portion is formed integrally with the upper frame, it is not necessary to attach it separately to the upper frame. Further, the hinge receiving portion integrally formed with the upper frame has higher strength than that separately attached, and therefore, the supporting strength of the spring supported by the fixing portion included in the upper frame can be sufficiently high. And furthermore, when opening the lid
The dew that falls from the surface is on the inner surface side of the lid and inside the upper frame (upper
Surface), there is no spring there,
The pulling is on the back side of the inner surface of the lid outside the dew drop area and
Since it is located outside the upper frame and is supported by the fixed part,
Dew does not reach the spring. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.
