BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker and, more particularly, to a configuration for preventing rice spilling from occurring during rice cooking.

[0002]

FIG. 19 is a longitudinal sectional view of a conventional rice cooker, and FIG.
0 is a top view thereof. In the figure, 1 is a rice cooker main body,
2 is a cover for covering the upper opening of the main body 1, 4 is an inner pot stored in the main body 1, 5 is an induction coil for heating the inner pot, 3
Reference numeral 1 denotes a steam port provided on the lid 2, and 32 denotes a steam container that guides steam generated during rice cooking to the steam port 31, separates steam from the steam, and returns the steam to the inner pot.

FIG. 21 shows a steam port 31 and a rice container 32.
It is sectional drawing of the part in which was provided. As shown in the figure, the rice container 32 includes an upper case 33 and a lower case 34, and is detachably attached to the lid 2. Steam containing rice generated during rice cooking enters the rice container 32 through a small hole 35 formed substantially at the center of the lower case 34 and a small hole 36 formed on the side surface of the upper case 33. An opening 37 formed substantially at the center of the upper case 33 has a small hole 35,
Since the diameter is larger than 36, the steam is weakened, the steam and the ash are separated, and the steam is discharged from the steam port 34 through the opening 37. Moreover, the tongue stored in the tongue container 32 is returned into the inner pan 4 from the small hole 35 when the heating is weakened and the internal pressure of the inner pan 4 decreases.

[0004]

In the conventional rice cooker, the spillage of the ash was prevented by the above-described configuration. However, even if the sneeze was accumulated in the ash container 32, the steam flowing from the small holes 35 was used. There was a problem that the rice was blown up and eventually spilled. In order to prevent spills, it is conceivable to reduce the heat immediately after boiling, but the temperature of the whole rice varies immediately after boiling. There is a problem that cooking is uneven.

Further, as shown in FIG. 22, a plurality of small holes 41 are formed separately from the steam inlet 40 into which the steam flows.
9 and cover the small hole 41 with a valve 42 made of a soft material such as rubber. That is, while the steam is being generated, the pressure presses the valve 42 against the small hole 41 to prevent the inflow of the steam, and when the internal pressure in the inner pan decreases, the valve 42 must be opened due to the weight of the ash. Returns to the inner pot 4. However, this method has a problem that the function of the soft material valve 42 is weakened due to aging, and the valve 42 is always opened.

The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a rice cooker which can surely prevent spillage of rice cake.
