[Detailed description of the invention] The present invention relates to an electric rice cooker such as a so-called electric jar rice cooker, and in particular, a heating plate is fixed to the inner bottom and the outer bottom wall and outer wall of the outer pot that houses the inner pot are heat-resistant. It is coated with a resin coating.

A general electric jar rice cooker has a bottomed cylindrical outer pot built into a frame, and an inner pot is housed in the outer pot and placed on a heating plate.
The heating plate is used to cook rice and keep it warm, but since the heating plate is housed and fixed at the inner bottom of the outer pot, the outer pot near the heating plate becomes quite high temperature, and the bottom wall and outer wall of the outer pot become very hot. There is a lot of heat dissipated from the heat sink, and it is necessary to take this heat dissipation into consideration when setting the heat output of the heating plate, which consumes more heat than necessary, making it uneconomical and inefficient.

In addition, this heat dissipation is even more noticeable when the outside temperature is low, such as in winter, and the time required from the start of cooking to completion becomes longer, and heat dissipates from the bottom and side walls of the outer pot. Electrical components or resin fittings installed between the frame and the frame may be adversely affected by heat and deformed.

Furthermore, as mentioned above, heat dissipation from the bottom wall of the outer pot adversely affects the rice cooking switch or other electrical components on the lower surface of the bottom wall of the outer pot, resulting in performance deterioration and thermal deformation of the bottom cover. -0 Also, it is necessary to select a material with high heat resistance for the heat insulating material between the frame and the outer pot in consideration of heat dissipation as described above, resulting in an increase in cost and various drawbacks.

As described above, the present invention includes a bottomed cylindrical outer pot attached to a frame with a heat insulating material interposed therebetween, a heating plate fixed to the inner bottom of the outer pot, and an inner pot provided in the outer pot so that it can be stored freely. Since the outer pot, the outer bottom wall, and the outer wall are coated with a heat-resistant resin coating, the heat indirectly transferred from the heating plate to the outer pot during rice cooking is absorbed by the resin coating. Due to the heat insulating effect, outward radiation from the bottom and side walls of the outer pot is minimized, and heating can be effectively achieved from the bottom and sides of the inner pot.
