FIG. 2 is a sectional view of a rice cooker according to an embodiment of the present invention, and FIG. 2 is a view showing displacement of a rice cooker when a maximum load is applied. The inner part of the main body 1 is composed of an inner container 2,
A weight sensor 4 is fixed to the inner container bottom 3, and a rice cooking heater 5 is fixed to the weight sensor 4. The weight sensor 4 is constituted by a cantilever spring 6, and the amount of deflection of the cantilever spring 6 changes according to the weight applied to the rice cooker 5. The amount of deflection is converted into an electric signal by a strain gauge 7 attached to a cantilever spring 6. The inner container 2 has the bottom 3 integrally formed, and the bottom 3 has a rising portion 8.
Are integrally formed, and the rice cooker 5 covers the rising portion 8. The inner pot 9 is formed separately from the main body 1, is removably stored in the main body, and rides on the rice cooker 5.

When the user puts cooked rice such as rice or water into the inner pot 9 and stores it in the main body 1, the inner pot 9 rides on the rice cooker 5,
In accordance with the weight of the inner pot 9, the rice cooker 5 sinks and the cantilever spring 6 is displaced. The displacement d is converted into an electric signal by the strain gauge 7 and sent to a control unit (not shown) in the main body 1 to perform water control or fire control. The displacement g of the cantilever spring 6 also changes the gap g between the bottom 3 and the rice cooker 5. Incidentally, the gap g 0 is Yes and the same or greater amount of displacement d 1 of cooking heater 5 when adding the maximum load (g 0 ≧ the rising portion 8 upper and cooking heater 5 prior to addition of the load
d 1 ), the rice cooker does not contact the rising part. In a rice cooker, rice grains attached to the outside of the inner pot 9 at the time of washing the rice fall into the body 1 or the rice grains dropped at the time of removing the rice often enter the inside of the body 1 and dry and harden. Accumulates at the bottom of the main body 1.
In the present invention, the rising portion 8 prevents foreign matter from entering the lower portion of the rice cooker 5, so that the downward movement of the rice cooker 5 is not hindered, and a stable weight detection output is always obtained.
