[0005]
By the way, recently, there is a tendency to favor health foods. As an example, germinated brown rice is eaten. This germinated brown rice is obtained by immersing brown rice in water at a suitable temperature for a long time. And the following are known as a cooking device which can manufacture such germinating brown rice.
[0006]
[Patent Document 2]
Japanese Patent No. 3165380 [0007]
This is because the heating pot (inner pot) is accommodated in the outer body (cooker body) with a built-in heater, the lid is placed so as to close the opening of the outer body, and the cover is immersed in water in the heating pot. The brown rice is heated for a long time, and then the germination process is performed, and after the germination process of the brown rice is completed, the rice cooking process is performed.
[0008]
In such an electric rice cooker, it takes a long time to germinate brown rice, so that dust and bacteria in the air do not enter the heating pot during this process, and the water temperature is kept slightly high. Therefore, it is necessary to cover the top of the heating kettle with a lid. The lid is preferably transparent so that the germination state of the brown rice accommodated in the heating pot can be confirmed. However, as described above, in an electric rice cooker, it is necessary to form an opening (steam hole) having a relatively large opening area in the lid body in order to prevent spillage during the cooking process. Even if you cover the top of the heating kettle with your body, not only can you prevent dust and bacteria in the air from entering the heating kettle during germination, but it also has low heat retention and reduces the water temperature in the heating kettle. Extra power is needed to keep it. For this reason, in patent document 2, the cover body used at the time of a germination process and the cover body used at the time of a cooking process are prepared separately. However, when the lid for germination treatment and the lid for cooking process are provided in this way, not only the lid used in the other treatment becomes an obstacle when performing one treatment, There was a problem of requiring extra space for storage.

Next, the operation of the present invention will be described. First, the germination process of brown rice will be described. First, a user wash | cleans the brown rice to germinate. Then, the washed brown rice is accommodated in the housing 8 in which the copper plate 9 is previously installed at the bottom and the antibacterial member 10 is installed on the copper plate 9. And the housing 8 in which this brown rice was accommodated is installed in the said inner pot 7, and a suitable quantity of water is poured. The appropriate amount of water in this case is an amount that is sufficiently larger than the amount of brown rice soaked in consideration of water absorption by the brown rice. And the inner pot 7 in which the said housing 8 was accommodated is installed in the inner case 3 of the said cooker main body 1, and is mounted in the said heat-transfer block 4. FIG. Further, the lid body 11 is placed on the flange portion 7A of the inner hook 7, and the opening / closing body 14 is rotated by gripping the rotary knob 25 so that the first steam hole 18 and the second steam hole 24 are rotated. Shift so that they do not overlap. When the lid 11 is placed on the inner hook 7, the knob 15 is gripped and lifted, so that the window 13 to which the knob 15 is attached is lifted and the inner side of the opening / closing body 14. The opening / closing body 14 also lifts in contact with the lower surface. Then, the lid base 12 loosely fitted with the opening / closing body 14 is also lifted. That is, the entire lid 11 is lifted by holding the knob 15 and lifting the window 13. Further, the operation unit 6 is operated to energize the heater 5. In this state, the heat generated by the heater 5 is transferred to the inner pot 7 through the heat transfer block 4 and the water in the inner pot 7 is warmed. Since both the steam holes 18 and 24 of the lid 11 are not in communication, it is only prevented that dust and bacteria in the air enter the inner pot 7 through the both steam holes 18 and 24. In addition, since the outside air hardly flows into the inner hook 7 and the air in the inner hook 7 does not flow out to the outside, the heat retaining property in the inner hook 7 is improved. For this reason, coupled with the fact that the casing 8, the copper plate 9, and the antibacterial member 10 in the inner pot 7 have antibacterial properties, not only can the inside of the inner pot 7 be kept hygienic, but also germination treatment. Electric power necessary for maintaining the water temperature in the inner pot 7 during the period can be suppressed. And the brown rice germinates by keeping the water in the inner pot 7 at a predetermined temperature for a predetermined time with the heater 5. The heater 5 is deenergized after a predetermined time has elapsed. And when the energization to this heater 5 stops, the brown rice germination state may be insufficient and may need to be reheated, but the brown rice state opens the lid 11 through the window body 13. Since it can be confirmed from the outside, the possibility that the lid 11 is opened to lower the water temperature in the inner pot 7 and consume extra power when re-warming can be eliminated.
[0028]
Next, the cooking process will be described. When cooking using germinated brown rice, the user removes the lid 11 from the inner pot 7 after the germination process is completed, grips the gripping portion 8C, and puts the germinated brown rice together with the casing 8 inside. Remove from kettle 7. Then, the water remaining in the inner pot 7 is discarded, the inner pot 7 is washed, the germinated brown rice in the casing 8 is washed, and the washed germinated brown rice is accommodated in the inner pot 7, An appropriate amount of water is poured into the inner pot 7. When cooking using white rice, the user sharpens the white rice and then stores the sharpened white rice in the inner pot 7. Further, the aforementioned germinated brown rice and sharpened white rice may be mixed and accommodated in the inner pot 7, and an appropriate amount of water may be poured into the inner pot 7. The appropriate amount of water poured into the inner pot 7 depends on whether the type of rice stored in the inner pot 7 is germinated brown rice, white rice, or mixed rice. It depends on the ratio of brown rice and white rice. Then, the inner pot 7 containing the rice and an appropriate amount of water is installed in the inner case 3 of the cooker body 1 and placed on the heat transfer block 4. Further, the lid body 11 is placed on the flange portion 7A of the inner hook 7, and the opening / closing body 14 is rotated by gripping the rotary knob 25 so that the first steam hole 18 and the second steam hole 24 are rotated. To overlap. Further, the operation unit 6 is operated to energize the heater 5. In this state, the heat generated by the heater 5 is transferred to the inner pot 7 through the heat transfer block 4 and cooked in the inner pot 7. In addition, since both the steam holes 18 and 24 of the said cover 11 are connected, the water vapor | steam produced | generated by the cooking is discharged | emitted to the exterior of the said cover 11 through the said both steam holes 18 and 24. A part of the generated water vapor is discharged to the outside of the lid body 11 from between the flange portion 7A of the inner hook 7 and the lower edge of the lid base 12 of the lid body 11. For this reason, even if the water in the inner pot 7 is boiled and foamed, the generated water vapor is discharged to the outside of the lid body 11 through the vapor holes 18 and 24 having a relatively large discharge area. Bubbles are prevented from spilling from the inner pot 7. And when the predetermined time passes, the said heater 5 will stop electricity supply and a cooking process will be complete | finished.
[0029]
Even if the rice stored in the inner pot 7 is germinated brown rice, white rice, mixed rice, or mixed rice, the water poured into the inner pot 7 depends on the ratio of germinated brown rice and white rice. Not only the appropriate amount is different, but also the difference in ease of spilling. Moreover, a difference arises in the ease of spilling also by the quantity of the rice to cook. For this reason, according to the kind, mixing ratio, and quantity of the rice accommodated in the inner pot 7, the opening / closing body 14 is rotated, and the degree of overlap between the first steam hole 18 and the second hole 24 is determined. That is, the opening areas of both the vapor holes 18 and 24 are adjusted. This reliably prevents bubbles from spilling from the inner pot 7. The lid base 12 and the opening / closing body 14 are in contact with each other at the foot portion 20 of the lid base 12 and the lower peripheral edge of the opening / closing body 14, and the installation portion 16 of the lid base 12 and the rib 23 of the opening / closing body 14. However, since the relatively small foot portion 20 is in contact with the lower peripheral edge of the opening / closing body 14 having a relatively small width, the contact area is relatively small, and the rib having a small width is also present. 23 and the installation portion 16 are in contact with each other, so that the contact area is relatively small, the opening / closing body 14 and the window body 13 are not basically in contact with each other, and the opening / closing body 14 is Although it is loosely fitted to the lid base 12, only the outer peripheral lower edge of the opening / closing body 14 and the rib 23 rest on the foot portion 20 and the installation portion 16. The lower edge and the rib 23 are connected to the foot portion 20 and the installation portion 1. Since the force that presses against is only gravity, in order to adjust the degree of overlap between the first steam hole 18 and the second hole 24, the rotary knob 25 is picked so that the opening / closing body 14 is moved. When rotating, the friction between the lid base 12 and the opening / closing body 14 is reduced, and the opening / closing body 14 can be rotated lightly.
[0030]
As described above, according to the present invention, the installation portion 16 is formed on the inner peripheral side of the inner pot 7 that is inserted into the cooker body 1 in which the heater 5 is provided. A substantially annular lid base 12 in which a first vapor hole 18 is formed, a transparent window body 13 installed in the installation section 16, and a substantially coaxial rotation with respect to the upper part of the lid base 12. An electric rod that covers the opening of the inner pot 7 with a lid 11 having a substantially annular opening / closing body 14 that is loosely fitted and has a second vapor hole 24 that can communicate with the first vapor hole 18. It is a cooking device, and the opening / closing body 14 is rotated with respect to the lid base 12 to adjust the positional relationship between the first steam hole 18 and the second steam hole 24, thereby cooking one lid body 11. It can be used for cocoon treatment and long-term germination treatment.
[0031]
Further, according to the present invention, since the diameter of the inner peripheral edge of the annular opening / closing body 14 is smaller than the outer diameter of the window body 13, when the window body 13 is lifted, the opening / closing body 14 and this The lid base 12 loosely fitted to the opening / closing body 14, that is, the entire lid 11 can be lifted.
[0032]
Further, according to the present invention, a rib 23 formed coaxially below the opening / closing body 14 abuts on the upper surface of the installation portion 16 of the lid base 12, and an inner diameter of the rib 23 is larger than an outer diameter of the window body 13. When the opening / closing body 14 is rotated, the opening / closing body 14 is formed at a height sufficient to prevent the opening / closing body from coming into contact with the window portion placed on the installation portion. The opening / closing body 14 can be rotated with little resistance without contacting the window portion 13.
