Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric cooker in which brown rice is germinated by heating brown rice at a low temperature for a long time. [0002] Brown rice germinated by heating at a low temperature for a long time is called so-called germinated brown rice and is considered to be rich in nutrition and good for health. A rice cooker in which germinated brown rice is obtained by paying attention to this is disclosed in Japanese Patent Application Laid-Open No. Hei 10-117713. In this prior art, brown rice and a predetermined amount of water are put in a pot and heated at a low temperature of 32 to 38 ° C. for about 18 to 24 hours to germinate a short length of rice. It is made to mix with white rice to cook normal rice. [0005] By the way, the most important thing to pay attention to to obtain germinated brown rice is to perform the operation under the condition of low temperature and long time, that is, normal food spoils as described above. For this reason, in the prior art, a container for holding brown rice is made of an antibacterial material such as copper, and the antibacterial ions of the copper prevent rot. When brown rice is germinated and eaten as described above, it is heated at a low temperature of 32 to 38 ° C. for a long time. If the outside air temperature is, for example, about 35 degrees, there is no need to heat. If brown rice and water are left in the pot and not heated for a long time, germination starts spontaneously, but if the outside temperature rises to 39 degrees or more, it is left for a long time without heating. Corruption will progress. Another point to be noted is that in the case of using a normal electric rice cooker to perform germination rice cooking and normal white rice cooking, the rice is kept warm immediately after finishing white rice cooking or at about 70 ° C. If the hot water and brown rice are put in a pot immediately after the end of the warming operation or during germination rice cooking, desired germination rice cooking cannot be performed. More specifically, the temperature of the pot may be as high as 38 ° C. immediately after the completion of rice cooking, but the user has a willingness to germinate brown rice and, as described above, the outside temperature. Even though the temperature was low, it was inconvenient that brown rice could not germinate in a pot at a relatively high temperature. According to the present invention, after confirming the stable temperature of the pot containing the brown rice, it is determined whether or not the germination rice can be executed, and the germination rice is cooked when certain conditions are provided. SUMMARY OF THE INVENTION The present invention relates to a method in which brown rice and water are stored in a pot and heated at a low temperature for a long time to perform germination rice cooking, and the water temperature is detected before or after the start of germination rice cooking. Water temperature detecting means, a water temperature determining means for detecting whether or not the water temperature is a predetermined low temperature, and a timer for starting counting of a predetermined time when the water temperature determining means outputs that the temperature is equal to or higher than a predetermined low temperature. Means for detecting the water temperature again by the water temperature detecting means after the time-up of the timer means and executing germination rice cooking when the temperature is below a predetermined low temperature, and stopping execution of germination rice cooking when the temperature is above a predetermined low temperature. It is. An embodiment of the present invention will be described with reference to the drawings. 1 is a flowchart of the electric cooker of the present invention, FIG. 2 is a sectional view of the same cooker main body, FIG. 3 is a block diagram of the same, and FIG. 4 is a pot (water) temperature characteristic diagram of the germinated rice cooker.

The control means (5) comprises a timer (6) for setting the germination time to 24 hours, and a timer (32) (reference temperature =
It comprises a temperature comparison circuit (7) serving as water temperature determination means for controlling the temperature to (low temperature), a rice cooking execution circuit (8) for cooking rice based on a predetermined program, and a water temperature detection circuit (9). A heat sensing element (10) is provided at the center of the bottom of the storage case (3) so as to be freely retractable. The temperature comparing circuit (7) and the water temperature detecting circuit (9) constitute a water temperature detecting means (H). (11) is a pot made of a polymer of stainless steel and aluminum and having a circular plane shape and a U-shaped vertical cross section, and the bottom is slightly raised in a mountain shape. The control means (12) is disposed and fixed in the space between the frame (2) and the storage case (3).
And (13) an operation display unit provided on the front upper portion of the frame (2), which is provided with a rice cooking button (not shown) such as a rice cooking button and a germination button, and a process display (14). . (15) is a contact plate unit which is provided so as to be housed in the pot and is made of an antibacterial material and has a king shape in plan view, which is constituted by three copper plates (16), (16) and (16). I have. A cover (17) is pivotally attached to the cooking device main body (1) so as to be openable and closable. Next, FIG.
The operation of germinated rice cooking will be described in conjunction with FIG. First, after the pot (11) is taken out and the contact plate unit (15) is stored and arranged, a predetermined amount of brown rice and water are stored between the copper plates of the unit and between the copper plate and the inner wall of the pan (S1). , (S2). The germination rice cooking course is selected by operating the germination button to start the germination rice cooking.
0) and the water temperature detection circuit (9) detect the pot temperature (t) (S3), (S4). Here, the temperature of the water put in the pot earlier is spring,
When the temperature is lower than 32 degrees, such as in autumn and winter, as shown in FIG. 4A, germination rice cooking is executed by the rice cooking execution circuit (8) from the beginning (S5), (S6), and then by another timer. For about 24 hours, germination is performed while maintaining the inside of the pot at 32 degrees, and when 24 hours have elapsed, the operation of the rice cooking execution circuit (8) is stopped and germination rice cooking is terminated. On the other hand, when the temperature of tap water is high from the beginning and the outside temperature is high, such as in summer, the temperature of the water in the pot becomes 32 ° C. or more before the start of germination rice cooking as shown in FIG. May have become. In this case, the timer (6) is operated for 10 minutes by the output of the temperature comparison circuit (7) based on the detection of the water temperature by the thermosensitive body (10) immediately after the start of germination rice cooking. The counting of (T) is started (S5), (S7). The timer (6) detects the water temperature again by the output of the timer (6) at the end of the 10-minute counting when the timer (6) can read the change of the water temperature by the thermosensitive element (10) and the water temperature detecting circuit (9). (S7), (S8),
(S9). In this season, the water temperature generally does not decrease even after 10 minutes have elapsed, and the detected water temperature is again 32 degrees or less. Therefore, the operation of the rice cooking execution circuit (8) is stopped and the alarm (18) is performed. (S10), and the execution of germinated rice cooking is stopped. Here, a case will be described in which germination rice cooking is started when the temperature of the pot itself is high immediately after the completion of white rice cooking. In this case, as shown in FIG. 4 (C), there is a process in which the temperature of the pot is lowered immediately after the completion of rice cooking and immediately after the pot is washed with water. (Description area of “elapse” in FIG. 4) When brown rice and water are added and the germination button is operated while the temperature of the pot is decreasing, the temperature of step (S5) is determined because the temperature of the pot is not sufficiently decreased. The water temperature detected in step 2 is 32 degrees or higher, and it should be judged that germination rice cooking should be stopped at this point. However, when the water temperature is 32 degrees or higher, the timer (6) counts 10 minutes. Start (S7). When the counting for 10 minutes is completed (S
8) The temperature of the water is detected again, and when the temperature is higher than 32 degrees, the execution of germination rice cooking is stopped, and when the temperature is lower than 32 degrees, germination rice cooking is executed. As described above, according to the present invention, when the water temperature is lower than a predetermined low temperature when the second water temperature is detected after a predetermined time has elapsed since the first water temperature detection, the germination rice cooking is performed. When the temperature is below the low temperature, the execution of germination rice cooking is stopped, so even if germination rice cooking is started when the temperature of the pot itself is high immediately after the completion of rice cooking, the water temperature may decrease over time. Is determined, germination rice cooking is performed, and desired germinated brown rice is obtained.
