In this way, the flow of the mixture of steam and slime that has flowed into the first steam flow passage RV1 undergoes a bending operation at the inflow stage into the second steam flow passage RV2, and the slime and steam are separated. be. In addition, when passing through the through-holes 66A, 72, 66B, the crumbs receive a defoaming action. The steam separated from the slime changes its advection direction upward again in the second steam flow passage RV2 and is discharged to the outside from the steam discharge port 61 . Note that the air-fuel mixture that was not separated into slime and steam at the stage of flowing into the second steam flow passage RV2 also flows into the second steam flow passage RV2 and flows again along the inner wall of the steam port guide 60. When changing direction, the flow undergoes a bending operation again to separate the slime and vapor.

The inner wall surface 67 of the steam port guide 60, particularly the inner wall surface 67 of the second steam flow passage RV2, is a slanted surface, which makes it easy for the scum to fall down along the slanted surface to the inner lid 80 side.

In the examples shown in FIGS. 5 and 6 (a) and (b), the lower end portion 73 is provided, for example, inclined toward the first steam flow passage RV1. Since the lower end portion 73 is elastic and inclined in one direction in this way, it is possible to prevent a gap from being formed in the contact surface between the lower end portion 73 and the inner lid 80 . .

A through hole 74 (third through hole) that communicates between the first steam flow passage RV1 and the second steam flow passage RV2 is provided in the lower portion of the partition seal member 71 (specifically, the lower end portion 73). The through hole 74 discharges the slime separated from the steam and accumulated in the second steam flow passage RV2 to the first steam flow passage RV1. The inside of the first steam flow passage RV1 is more airtight than the inside of the second steam flow passage RV2. drawn inside. The protruding portion 64 and the partition seal member 71 protruding downward from the protruding portion 64 also function as a weir that dams up the slime in the first steam flow passage RV1 and the second steam flow passage RV2.

The through hole 74 is formed smaller than the through holes 66A, 66B, and 72. As shown in FIG. The slime discharged into the second steam flow passage RV2 in the form of bubbles when passing through the through-holes 66A, 66B, and 72 is crushed by the through-hole 74 when passing through the through-hole 74, thereby defoaming. receive.

The cocoa discharged from the second steam flow passage RV2 to the first steam flow passage RV1 through the through hole 74 returns to the inner pot 10 through the through hole 88 as described above. According to this embodiment, as described above, the inner lid 80 is formed with the through hole 88 that communicates with the first steam flow passage RV1. Also, the first steam flow passage RV1 and the second steam flow passage RV2 are communicated with each other at the lower portion of the partition seal member 71, and the slime accumulated in the second steam flow passage RV2 is discharged to the first steam flow passage RV1. A through hole 74 is provided. For this reason, according to the present embodiment, the through hole 88 for discharging the mixture of the steam and the sticky matter generated in the inner pot 10 to the outer lid 40 side is used to remove the steamed sticky matter from the inner pot 10 . can be returned inside. Therefore, the sticky rice separated from the steam can be returned to the inner pot 10 with a simpler structure than the conventional one.

As described above, according to the present embodiment, the space between the outer lid 40 and the inner lid 80 is surrounded by the frame-shaped sealing member 55 without providing a dedicated steam unit for storing the slime. Steam and slime can be separated from a mixture of steam and slime that has flowed from the inner pot 10 into the lid 30 in the steam flow passage RV. After the separated sticky matter is once stored in the steam flow passage RV (that is, the first steam flow passage RV1 and the second steam flow passage RV2), it can be returned to the inner pot 10. Therefore, it is not necessary to provide a storage housing for the steam unit, and the internal space of the lid 30 can be fully utilized.

In addition, the first steam flow passage RV1 and the second steam flow passage RV2 that store the slime are the spaces between the outer lid 40 and the inner lid 80 as described above. It can be easily exposed by simply removing it. Moreover, both the frame-shaped seal member 55 and the partition seal member 71 that define the first steam flow passage RV1 and the second steam flow passage RV2 are provided on the outer lid 40 . As shown in FIG. 1 , the inner lid 80 is not provided with a sealing member for defining the steam flow passage RV between the outer lid 40 and the inner lid 80 .
