Next, the operation of the bean container 10 when rice is cooked by the rice cooker to which the above-mentioned bean container 10 is attached will be described. When the inner pot 5 containing water and rice is housed in the rice cooker body 1 and the lid 2 is closed and the power switch provided in the operation unit 8 is turned on, the inner coil 5 is heated by the action of the induction coil 6, When the water in the inner pot 5 boils, steam containing a stick is generated. At this time, since the internal pressure of the inner pot 4 is rising, the on-off valve 20 of the agar container 10 is pushed up to close the return hole 19 as shown in FIG. The steam containing the stick is guided from the steam inlet 16 through the guide tube 15 into the stick container 10.

The steam containing the alum that has left the guide tube 15 and collided with the inner wall of the first upper barrier 29 diffuses in the abacus container 11 toward the vapor port 28, as indicated by the arrow. During this time, the steam and the steam are separated, and the steam is discharged to the outside from the steam port 28, and the steam is accumulated in the accumulation recess 17.

As described above, the steam containing the tongue is separated from the steam and the tongue in the space from the guide tube 15 to the steam port 28. Therefore, the longer the distance between the guide tube 15 and the steam port 28, the more separated. Easy to do. In the present invention, the steam containing the weeds collides with the first upper barrier 29, the second upper barrier 30, the lower barrier 21, and the third upper barrier 32 after leaving the guide tube 15.
Since the flow flows in a meandering manner, the distance between the guide cylinder 15 and the steam port 28 becomes longer, and the separation is achieved more reliably. In this case, the bean that has fallen rearward from the lower barrier 21 is inclined so that the bottom of the lower case 11 is lowered toward the accumulating recess 17, and the central portion of the lower barrier 21 projects rearward. Since it is formed in a substantially V shape, it flows along the surface of the lower barrier 21 and flows into the reservoir recess 17 through the openings 21a on both sides.

When the heating is stopped and the internal pressure of the inner pot 5 is lowered, the on-off valve 20 is lowered by its own weight of the on-off valve 20 and the weight of the stick, as shown in FIG.
9 is opened. As a result, the bean that has accumulated in the reservoir recess 17 drops from the bean return hole 19 into the inner pot 5 through the steam hole provided in the recess 3e of the inner lid 2c. By returning the rice cake to the rice in the inner pot 5, the tasty ingredients contained in the rice cake are added to the rice, and the rice can be cooked with a glossy and sticky taste.

By the way, due to water addition and other reasons, the steam containing the weeds increases, and as shown in FIG. 13, the weeds overflow from the reservoir recesses 17 to fill the lower case 11, and 2 may reach near the upper barriers 29, 30. Even in such a case, the steam including the weeds that has come out of the guide tube 15 flows out from the lower wall portion on the front side of the first upper barrier 29, and the outer circumference of the first upper barrier 29, the second
It collides with the 3rd upper barrier 32 through the opening part 31 of the upper barrier 30, and during that, vapor | steam and a tongue are isolate | separated and a vapor | steam is discharged | emitted outside from the vapor | steam port 28, and a tongue falls in the container 10 of an aunt. .

As described above, according to the present invention, the lower wall portion is provided in the first upper barrier 29 and the opening portion 31 is provided in the second upper barrier 30, so that the first and second layers are arranged. Upper barrier 29,
Even if it accumulates near the lower part of 30, the steam containing the sticks can flow through the sticker 10 without any trouble to separate the steam and the sticks, and the steam can be released from the steam port 28 to the outside to drop the sticks. it can.

When the rice is cooked, the hook 23 is rotated to separate the upper case 25 from the lower case 11, washed with water, and then attached to the lower case 11 again. Needless to say, container 10
The lower case 11 and the upper case 25 may be separated from each other by removing from the lid 2 and washed with water. In addition, if the aquarium container 10 is formed of an antibacterial plastic, the propagation of various bacteria can be suppressed and the cleanliness can be maintained.

As described above, according to the present invention, the bean is surely separated from the steam by the bean container 10 and accumulated in the accumulating recess 17, so that the bean does not spill out to the outside from the steam port 28. Further, even if a large amount of the bean is accumulated in the bean container 10 due to water addition or other reasons, the flow of the vapor including the bean is not obstructed, and the bean is reliably separated to remove the vapor to the outside. It can be discharged, and it is possible to prevent the tongue from spilling outside from the steam port 28. Furthermore, since there is no spillage even on high heat, the high heat can be continued until just after boiling the water, so that delicious rice can be cooked evenly.

At this time, since the internal pressure of the inner pot 5 is rising, the on-off valve 20 of the agar container 10 is pushed up to close the return hole 19 as shown in FIG. 11, and therefore, The steam containing the stick is guided from the steam inlet 16 through the guide tube 15 into the stick container 10.

The steam including the agate that has left the guide tube 15 and has collided with the inner wall of the first upper barrier 29 diffuses in the abacus container 11 toward the vapor port 28 as indicated by an arrow in FIG. During this time, the steam and the steam are separated from each other, and the steam is discharged to the outside from the steam port 28, and the steam is accumulated in the accumulation recess 17.

As described above, the steam containing the tongue is separated from the steam and the tongue in the space from the guide tube 15 to the steam port 28, so that the longer the distance between the guide tube 15 and the steam port 28 is to the separation. Easy to do. In the present invention, the steam containing the weeds collides with the first upper barrier 29, the second upper barrier 30, the lower barrier 21, and the third upper barrier 32 after leaving the guide tube 15.
Since the flow flows in a meandering manner, the distance between the guide cylinder 15 and the steam port 28 becomes longer, and the separation is achieved more reliably. In this case, the bean that has fallen rearward from the lower barrier 21 is inclined so that the bottom of the lower case 11 is lowered toward the accumulating recess 17, and the central portion of the lower barrier 21 projects rearward. Since it is formed in a substantially V shape, it flows along the surface of the lower barrier 21 and flows into the reservoir recess 17 through the openings 21a on both sides.

When the heating is stopped and the internal pressure of the inner pot 5 is lowered, the on-off valve 20 is lowered by the weight of the on-off valve 20 and the weight of the aunt, as shown in FIG.
9 is opened. As a result, the bean that has accumulated in the reservoir recess 17 drops from the bean return hole 19 into the inner pot 5 through the steam hole provided in the recess 3e of the inner lid 2c. By returning the rice to the rice in the inner pot 5, the delicious component contained in the rice is given to the rice, and the delicious rice with a glossiness can be cooked.

By the way, due to water addition and other reasons, the steam containing the weeds increases, and as shown in FIG. 13, the weeds overflow from the reservoir recesses 17 and fill the lower case 11, and 2 may reach near the upper barriers 29, 30. Even in such a case, the steam including the weeds that has come out of the guide tube 15 flows out from the lower wall portion on the front side of the first upper barrier 29, and the outer circumference of the first upper barrier 29, the second
It collides with the 3rd upper barrier 32 through the opening part 31 of the upper barrier 30, and during that, vapor | steam and a tongue are isolate | separated and a vapor | steam is discharged | emitted outside from the vapor | steam port 28, and a tongue falls in the container 10 of an aunt. .

As described above, according to the present invention, since the lower wall portion is provided in the first upper barrier 29 and the opening portion 31 is provided in the second upper barrier 30, the first and second layers are arranged. Upper barrier 29,
Even if it accumulates near the lower part of 30, the steam containing the sticks can flow through the sticker 10 without any trouble to separate the steam and the sticks, and the steam can be released from the steam port 28 to the outside to drop the sticks. it can.

When the rice is cooked, the hook 23 is rotated to separate the upper case 25 from the lower case 11, washed with water, and then attached to the lower case 11 again. Needless to say, container 10
May be removed from the lid body 2 to separate the lower case 11 and the upper case 25 and washed with water, so that disassembly, coupling and cleaning are extremely easy. In addition, if the aquarium container 10 is formed of an antibacterial plastic, the propagation of various bacteria can be suppressed and the cleanliness can be maintained.

As described above, according to the present invention, the bean is surely separated from the steam by the bean container 10 and accumulated in the accumulating recess 17, so that the bean does not spill out to the outside from the steam port 28. Further, even if a large amount of the bean is accumulated in the bean container 10 due to water addition or other reasons, the flow of the vapor including the bean is not obstructed, and the bean is reliably separated to remove the vapor to the outside. It can be discharged, and it is possible to prevent the tongue from spilling outside from the steam port 28. Furthermore, since there is no spillage even on high heat, the high heat can be continued until just after boiling the water, so that delicious rice can be cooked evenly.

Further, a locking portion 22 is provided on one side of the peripheral wall 13 of the lower case 11, a locking mechanism 23 is provided on the other side, and the locking portion 22 is engaged with one side of the peripheral wall 27 of the upper case 25. The engaging portion 33 is provided on the other side, and the engaging portion 34 to be engaged by the lock mechanism 23 is provided on the other side.
Since the annular packing 36 is clamped by the peripheral edge of the, the disassembly and connection and the cleaning are easy, and there is no fear that the steam containing the abdomen leaks.
