(Knowledge that became the basis of the present invention)
As a result of diligent studies to further suppress the deformation of the portion near the hinge portion, the present inventors have obtained the following findings.

The pressure type rice cooker cooks rice by pressurizing the inside of the pot. In a pressure-type rice cooker, the pressure inside the pot is higher than the atmospheric pressure, so a strong pressure is applied so that the portion of the lid located above the pot is lifted. At this time, an upward force is applied to the hinge portion to which the lid is attached, and the portion in the vicinity of the hinge portion is easily deformed.

In order to suppress the deformation of the portion near the hinge portion, it is conceivable to simply provide a reinforcing member separately in the deformable portion. However, in this case, the reinforcing member becomes large in size, which may cause an increase in manufacturing cost. In addition, a large space is required to install the reinforcing member, which limits the degree of freedom in design.

On the other hand, when the pressure inside the pot becomes higher than the atmospheric pressure, a downward force that pushes down the pot is also generated. As a result of diligent studies, the present inventors have found a configuration in which a hinge reinforcing member connected to a hinge portion is extended below the flange portion of the pan and is brought into direct or indirect contact with the lower surface of the flange portion. According to this configuration, the downward force applied to the pan is received by the hinge reinforcing member, and the downward force is applied to the hinge portion via the hinge reinforcing member to reduce the upward force applied to the hinge portion. Can be done. As a result, deformation of the portion near the hinge portion can be suppressed. In addition, according to this configuration, it is possible to suppress the increase in size of the reinforcing member, reduce the weight of the reinforcing member, simplify the structure, reduce the manufacturing cost, and improve the degree of freedom in design by reducing the installation space. Can be done. Based on this new finding, the present inventors have arrived at the following inventions.
