(Water level adjustment)
Next, the water level adjustment operation using the inner pot 10 and the operation of the water level scale 20 will be described. FIG. 3 is a diagram for explaining the operation of the water level scale 20 according to the first embodiment. In FIG. 3, L1 and L2 indicate the water level, and W1 and W2 indicate the width of the painted portion 22 at the water level position (distance between the zigzag portion 21a and the zigzag portion 21b).

When adjusting the water level, first put the polished rice into the inner pot 10, then add the approximate amount of water according to the amount of rice to be cooked, and then compare the scale and water level with water. It is common to adjust.
In the water level scale 20 according to the first embodiment, the bent portion S and the bent portion T indicate the water level. That is, the position indicating the water level is one point of the bent portion S or the bent portion T, and there is no ambiguity as in the case of providing a thick water level scale as in the prior art. In addition, since the side connecting the bent portion S and the bent portion T of the zigzag portion 21 intersects the water surface, the user can easily grasp the current water level by checking the intersection of the water surface and the zigzag portion 21. it can.

FIG. 3 is a diagram for explaining how the water level is adjusted to the position “3 go”. When the water level is adjusted to “3 go”, first, an approximate amount of water is added to obtain the water level L1, and then, as shown in FIG. It is common to add water little by little to match. At this time, as water is added to raise the water level L1, the width W1 on the painted portion 22 at the water level position gradually decreases. By confirming this width W1, the user can easily recognize the degree of increase in the water level, so that the water level can be easily adjusted.
Further, since the bent portion S and the bent portion T are formed at an acute angle, the inclination of each side constituting the zigzag portion 21 is larger than when formed at an obtuse angle. For this reason, when the amount of water is changed, the amount of change in the widths W1 and W2 is large.
