  Recent electric rice cookers are equipped with a microcomputer, and this microcomputer adjusts the rice rice cooking menu that can cook rice according to rice types such as white rice and brown rice, hard and soft etc. You can select your favorite rice menu that allows you to cook rice, a rice cracker menu that lets you cook rice porridge, and a rice cooking menu that burns the cooked rice. Moreover, what provided the miscellaneous cooking function of cooking miscellaneous cooking from the already cooked rice other than such a normal rice cooking menu is known (for example, refer the following patent documents 1 and 2).

  For example, the following patent document 1 discloses a rice cooker having a miscellaneous cooking heating function. This rice cooker has an inner pot that is detachably stored in the main body, a heating part that heats rice and water put in the inner pot, a control part that controls the heating part, and an operation for input operation to the control part. And the operation unit is provided with a selection means for selecting miscellaneous cooking heating that adds water to the cooked rice and heating it, and when the cooking means heating is selected by the selection means, until boiling is detected by the boiling detection means Heating is performed with a strong fire, and after boiling, the heating is stopped, or the heating is decreased for a certain time and then terminated.

  Specifically, as shown in FIG. 7, in the rice cooker of Patent Document 1 below, cooked rice, that is, cooked rice (β starch), is heated and boiled to a high temperature of 98 ° C. or higher. By using rice that has been held for 20 minutes or more (α starch), so-called pre-gelatinized rice, it is heated at a high heating amount at the same time as it is started, boiled for about 10 minutes and boiled for about 10 minutes, and then heating reduction or heating is stopped. .

The miscellaneous cooking process has the fastest miscellaneous cooking process I which rapidly cooks miscellaneous cooking, and the favorite cooking process II which can change a heating time arbitrarily according to a user preference after completion | finish of the fastest miscellaneous cooking process I. The fastest miscellaneous cooking process I further includes a boiling process I _{A for} heating and heating until the water in the pan 4 is boiled, and a cooking process and steaming process I _B for heating the miscellaneous cooking utensil at a constant temperature K1 after boiling the water and steaming. have. In addition, the heating time T1 of the fastest miscellaneous cooking process I is 15 minutes.

  For mixed cooking, warm cooked rice, cold rice, frozen rice, etc. can be used, but all of these are already cooked and the rice is sufficiently alpha, so during normal cooking, A so-called water absorption step is not required, and the pan 4 can be heated and heated immediately.

  In the fastest miscellaneous cooking process I, the heating time is fixed at T1, and in the favorite miscellaneous cooking process II, the additional heating time T2 is set between 0 minutes and 45 minutes.

  That is, the total cooking time T in miscellaneous cooking is T1 + T2, and is arbitrarily selected between 15 minutes and 60 minutes.

  In FIG. 4, A represents the pan bottom temperature, B represents the steam temperature, and C represents the temperature at the center of the frozen rice lump. In the fastest miscellaneous cooking process I, the steam temperature B reaches K1 after a while after the pan bottom temperature A reaches K1. Thereafter, after about 15 minutes later, the temperature C at the center of the frozen rice lump reaches K1, and the fastest miscellaneous cooking process I is finished at this point. At the end of the fastest miscellaneous cooking process I, the miscellaneous cooking is fully heated, but by setting up your favorite miscellaneous cooking process II, you can set the user's arbitrary heating time and make the sticky and heated ingredients preferred Can be adjusted accordingly.

  The 15 minutes of time T1 and the longest time of 45 minutes of time T2 are the time set based on the experiment, but if it is 15 minutes of time T1, mixed rice cookers such as raw meat and seafood on frozen rice chunks Even when using, the frozen rice can be thawed smoothly, and the cooked rice can be easily cooked in the shortest time without the cooked rice being boiled. Moreover, when the favorite miscellaneous cooking time becomes a long time, the moisture in the pan decreases, and the miscellaneous cooking may burn, but by setting the maximum time of T2 to 45 minutes, the burning can be suppressed.

  Hereinafter, the flow of the cooking process will be described with reference to FIGS. 5 and 6. When cooking miscellaneous cooking in the rice cooker 1 of this embodiment, first, select miscellaneous cooking rice from the rice cooking menu (S301), and then set the total miscellaneous cooking heating time T between 15 minutes and 60 minutes for the user's arbitrary cooking time. When selected (S302), the reservation timer function is disabled in the control means 27 (S303), the pressure valve 18 is opened (S304), and the fastest miscellaneous cooking process I is started (S305).

  At this time, the reservation timer function is disabled, so that rice in the pot 4 and uncooked miscellaneous cooking utensils, especially unheated meat, seafood, etc. are left in the pot 4 for a long time and are prevented from decaying. The Moreover, since the forced stirring function in the pan 4 is invalidated during miscellaneous cooking by fixing the pressure valve 18 in an opened state, miscellaneous cooking utensils or the like adhere to the pressure valve 18 and the pressure valve 18 is blocked. It is possible to suppress the occurrence of abnormal pressure and suppress an abnormal increase in pressure to ensure safety.

  In addition, in the rice cooker 1 of this embodiment, after selecting the miscellaneous cooking, the total miscellaneous cooking heating time T is set from 15 minutes to 60 minutes, but is added to the heating time T1 (15 minutes) of the fastest miscellaneous cooking process I. The additional heating time T2 may be set between 0 minute and 45 minutes.

In fastest porridge step I, the timer counts the heating time T1 is started (S306), the process proceeds to the boiling step I _A (S307). In the boiling process I _A , the inside of the pan 4 is heated with full power by the heating means 5 (S308), and the temperature in the pan 4 rises rapidly. Thereafter, the pot bottom temperature is detected by the pot bottom temperature sensor 30b, and it is determined whether the pot bottom temperature has reached a predetermined temperature K1 (100 ° C.) (S309, S310). If the pot bottom temperature has not reached the predetermined temperature K1 (“ N ”), the energization of the heating means 5 is continued. On the other hand, when it is determined that the pan bottom temperature has reached the predetermined temperature K1 (in the case of “Y”), the boiling process I _A is completed, and the process proceeds to the cooking and steaming process I _B (S311).

In ingredients Cooking & steaming step I _B, until T1 has passed, the energization of the heating means 5 for maintaining a predetermined temperature K1 is performed at a predetermined interval for a predetermined time (S312). Then, it is determined whether or not the heating time T1 has passed (S313). When the heating time T1 has not passed (in the case of “N”), the heating means 5 is continuously energized at a predetermined time interval. . On the other hand, when the heating time T1 has elapsed, the total cooking time T set at the start of the cooking is continuously read (S314), and it is determined whether T is equal to T1 (S315). If T is equal to T1 (in the case of “Y”), the process proceeds to the heat retaining step or the power supply to the heating means is turned off. By shifting to the heat retention step, the cooked rice can be stored warm. Moreover, when heat insulation is unnecessary, it stops heating and suppresses that miscellaneous cooking becomes paste-like.

  On the other hand, in T315, when T is longer than T1 (in the case of “N”), the process proceeds to a favorite cooking process II (S316). In the favorite miscellaneous cooking process, a timer count of a time T2 obtained by subtracting the heating time T1 of the fastest miscellaneous cooking process from the total miscellaneous cooking process T is started (S317), and the energization to the heating means 5 is performed at predetermined time intervals (S318). . Subsequently, it is determined whether or not the additional heating time T2 has elapsed (S319). When the additional heating time T2 has not elapsed (in the case of “N”), the heating means 5 is continuously energized at a predetermined time interval. Is done. On the other hand, when the additional heating time T2 has elapsed (in the case of “Y”), the process proceeds to the heat retaining step or the energization to the heating means is turned off.

  By providing the above-described configuration, according to the rice cooker of the present embodiment, miscellaneous cooked rice according to the user's preference can be obtained using the remaining rice or lump of frozen rice and various miscellaneous cookers. In other words, when only the fastest miscellaneous cooking process is executed in the miscellaneous cooking menu, it can be cooked in the shortest time, and when the favorite miscellaneous cooking process is executed, the amount of moisture, stickiness, the heating state of ingredients, etc. are fine. You can cook your favorite cooking.
