れ、その上部は蒸気口１１により外部に連通している。A cylindrical spill control chamber 9 is formed in the lid body 6 and penetrates through the heat radiating plate 7 and is opened downward. A mucus reservoir 10 is provided in the spill control chamber 9, and the upper portion thereof is provided. The steam port 11 communicates with the outside.

る。In the mucus reservoir 10, a plurality of through holes 13 communicating with the inside and outside of the cylindrical portion 12 are formed in the outer peripheral surface of the upper portion of the cylindrical portion 12, and a flexible rubber is formed inside the through hole 13. The check valve 14 is formed, and only the inflow of mucus is permitted.

に還元されるようになっている。A discharge port 15 is formed at the bottom of the cylindrical portion 12, and the discharge port 15 is normally closed by a discharge valve 16 also made of flexible rubber. When it accumulates, the discharge valve 16 depends on its weight.
Is pushed down to open the outlet 15, and the mucus is reduced into the inner container 5.

加熱手段の出力を低下させるようになっている。Reference numeral 17 denotes a micro switch. The tip of an arm 18 for operating the micro switch 17 is in contact with the lower surface of the discharge valve 16. As described above, the discharge valve 16 is depressed so that the arm 18 is moved. When the micro switch 17 moves downward, the opening of the discharge valve 16 is detected, the electric circuit of the heating means is controlled, and thereafter the output of the heating means is reduced for a predetermined time.

て泡の表面が上昇する。In order to cook rice with the electric rice cooker 1, rice and water are put into the inner container 5, and the heating means of the outer container 4 is heated and heated, so that the rice absorbs water and swells. At the same time, the starch content of the rice is dissolved in water to increase the viscosity, and as the water boils, mucous foam is generated, and the surface of the foam increases as the viscosity of the water increases.

粘液が粘液溜め１０内に滞留すると共に、水蒸気は蒸気
口１１から排出される。When the inside of the inner container 5 is filled with foam, a part of the foam pushes the check valve 14 open as shown in FIG. When the bubbles enter the wide mucus reservoir 10, the bubbles pop, the generated mucus stays in the mucus reservoir 10, and the steam is discharged from the steam port 11.
【００２０】粘液溜め１０内に粘液がある程度溜まる

せしめられて、マイクロスイッチ１７が作動する。When a certain amount of mucus accumulates in the mucus reservoir 10, the weight of the mucus causes the discharge valve 16 to move as shown in FIG.
Is opened, the mucus in the mucus reservoir 10 is discharged downward from the outlet 15, and the arm 18 is moved downward by the discharge valve 16, and the microswitch 17 is operated.

粘液が排出された後は、再度排出弁１６は上動し、当該
排出弁１６によって排出口１５は閉塞される。When the microswitch 17 is operated, the output of the heating means is controlled to reduce the output for a predetermined time. This reduces the amount of heat added to the water, the rate of defoaming exceeds the rate of boiling of the water, the surface of the foam is reduced, and only water vapor is discharged from the through hole 13 through the mucus reservoir 10 through the steam port 11. . After the mucus in the mucus reservoir 10 is discharged, the discharge valve 16 moves up again, and the discharge port 16 is closed by the discharge valve 16.

手段の出力が低下する。After a lapse of a predetermined time, the output of the heating means recovers again and heats strongly, so that the inner container 5 is filled with bubbles, a part of the bubbles enters the mucus reservoir 10, and the bubbles are removed. The mucus generated by the bursting stays in the mucus reservoir 10, and when the amount reaches a predetermined amount, the outlet 15 is opened to discharge the mucus, and the microswitch 17 is operated to lower the output of the heating means. .

きこぼれを防止する。According to the present invention, when the inside of the inner container 5 is filled with foam and the mucus stays in the mucus reservoir 10 to some extent, and immediately before the mucus is ejected or spilled out from the steam port 11, the discharge valve 16 is provided. Is opened and the microswitch 17 is activated, the output of the heating means is reduced, and the generation of bubbles is suppressed, thereby preventing spillage.

分に美味い飯を炊くことができるのである。Therefore, according to the present invention, the output of the heating means is reduced immediately before the spillover, so that the output of the heating means is set to be sufficiently large without considering the spillage due to overheating. You can cook delicious rice on high heat.

い。Further, since the heating means is controlled by operating the microswitch 17 according to the amount of mucus staying in the mucus reservoir 10, even if the conditions such as the amount of cooked rice and the water level change, the heating means is turned on immediately before the spill. Since the output automatically decreases, there is no need to change the control conditions according to these conditions.
