得難いという問題がある。(Problem to be Solved by the Invention) In the above-mentioned direct heating rice cooker, the heat from the heating plate 3 is transferred to the container 2.
Since the water is transmitted directly to the bottom of the rice and is cooked from the bottom layer to the middle layer and then to the top layer, the water required to cook the top layer of the rice tends to be insufficient, causing a difference in the moisture content of each layer of rice, and as a result, the rice is not fully cooked. There was a problem in that the condition varied. The radiant heating rice cooker is a so-called furnace cooking style, and due to the heating structure mainly using the rice cooker heater 9, the rice is cooked from the top layer to the middle layer and then to the bottom layer in that order by water convection as shown by the arrow. When the rice is cooked in the upper layer, sufficient water remains, and the difference in moisture content between each layer of rice is smaller than with the direct heating method. However, this method mainly uses water convection to cook the upper layer of rice first, so there is a problem that it is difficult to obtain a sufficient oven-cooking effect.

温度上昇し、米１８の上層部Ａと他の中。When cooking rice, first put a predetermined amount of rice 18 and this rice 1 into the container 16.
This container 1 contains a predetermined amount of water 19 necessary for gelatinization of 8.
6 is housed in the inner case 13 of the container body 11, and! ! Close 21. As a result, the top opening of the container 16 is opened by the lid gasket 2.
3 and is closed by an inner lid 24. Then, when you press the rice cooking switch 41 to start cooking, the first rice cooking heater 1
5 is energized by about 67% manual power (for example, soow), and the second rice cooking heater 36 is energized by 100% input (for example, 60%
0W), and the blower 33 is driven. As a result, the container 16 is heated by the first rice-cooking heater 15, and the air in the lower heating space 14 heated by the first rice-cooking heater 15 is sucked into the air passage 29 from the air supply port 32 and rises. The rice is further heated by the rice cooking heater 36 of No. 2, and the rice is heated from the air outlet 31 to the upper heating space 14 above the container 16.
The heating space 1 is blown out to A and wraps around the container 16.
4. Cycle through 14A and 14B. Further, the control means 47 determines whether the container temperature gradient and the air temperature gradient are appropriate based on the detection signals of the container temperature detection means 45 and the air temperature detection means 46, and determines that dry cooking is occurring when the gradient is abnormally steep. Cut off the power. Further, the control means 47 performs cooking according to the set heating pattern when the temperature gradient is appropriate, that is, after the water 19 in the container 16 is heated to an appropriate temperature by the soaking process and the water 19 has sufficiently permeated into the rice 18. Move on to the actual cooking process. In this rice cooking process,
The gelatinization of the rice 18 starts at a water temperature of 55 to 70°C, but within this temperature, the degree of gelatinization is very slight, and becomes active after the water temperature reaches a boiling state of 98°C or higher. Under such boiling conditions, the water 19 in the container 16 is actively absorbed into the rice 18, and the rice is cooked after a required period of time. In this case, the heated air blown out from the outlet 31 of the feeder 29 is blown onto the upper part of the container 16, and the temperature of the upper layer A of the name rice 18 rises faster than the middle layer B and the lower layer C, and 18 upper A and others inside.

行程に移行する。The temperature difference between the lower layers B and C becomes larger, and as a result, the upper layer A of the rice is cooked first in a short time, and the water 19 is trapped below the upper layer A of the cooked rice 18. Then, the control means 47 determines that the rice upper layer A is finished cooking when the air temperature detected by the air temperature detection means 46 does not reach a set temperature lower than the cooking temperature, for example, 95° C., and turns off the power to the second rice cooking heater 36. While stopping the air blower R33, the first rice cooking heater 1
Switch the input of No. 5 to 100% (800W). As a result, the middle and lower layers B and C of the rice 18 sufficiently absorb the water 19 trapped below the upper rice layer A and are cooked, and when the container temperature reaches the cooking temperature (for example, 120°C), The power to the first rice cooking heater 15 is cut off to complete the rice cooking, and the process proceeds to a heat retention process.

The air in the container 16 is sucked into the air passage 29 from the air supply port 32 as shown by the arrow in FIG.
Since the rice is blown upward, the upper part of the container 16 is forcibly heated and the upper part A of the rice 18 is cooked first and in a short time. The rice 18 is cooked by confining the water 19 in the upper layer A and absorbing enough water into the rice middle layer B and the lower rice layer C to gelatinize and cook the rice. The water absorption rates of B and C are made uniform, and variations in the cooked rice are suppressed, resulting in delicious rice. In addition, the heated air blown out from the outlet 31 wraps around the container 16 in the heating space 14.14A,
Since the rice 14B is circulated, the rice 18 in the container 16 can be cooked completely fluffy. Furthermore, since the water 19 is trapped in the lower part of the rice by the upper layer A of the rice that is cooked first, it is possible to prevent the generation of sticky rice during cooking.

The same parts as in the first embodiment are given the same reference numerals, and explanations of the same parts are omitted. A heating plate 55 having a rice cooking heater 54 is provided at the bottom of the inner case 13, and the container 7 is placed on the heating plate 55.
In this case as well, the heated air is blown out from the outlet 31 of the air passage 29 to the upper part of the container 16, and as a result, the upper rice layer A
The rice is cooked first, and the water 19 is trapped below by the upper layer A of the rice 18, and the lower layer C1 of the rice 18 and the middle layer B are fully absorbed and cooked, so that the rice is cooked evenly. You can get delicious rice and prevent the generation of sticky rice.
