How to control the cooking process of rice cooker with electric heaters

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

In particular, the present invention relates to a method of controlling a rice burning process of an electric heat-insulating rice cooker, wherein the burning rice can be cooked by controlling the absorption time, the heating process, the boiling maintenance process, And it is characterized in that when the rice cooker is applied to an electric heat-insulated rice cooker, the cooked state of the rice cake can be maintained at an optimal level.

As is well known, the electric heat-preserving rice cooker has an operating environment for each process according to each contents, and the process starts according to the operation of each cooking key after the state where the inner pot is seated for the first time is detected.

As shown in the block diagram of FIG. 1, the general thermosensible rice cooker includes a key input unit 12 configured by keys for setting various operating environments of the thermosensible rice cooker having a cooking function and a thermostatting function, And a controller for controlling the temperature of the rice cooker according to the temperature detected by the key input of the key input unit and the temperature sensor. The temperature sensor detects the temperature of the rice cooker, A microprocessor 10 for controlling the operation of the thermo-electric cooker, a microprocessor 10 for controlling the operation of the heater for heating the inside of the thermo-electric cooker, under the control of the microprocessor 10, A heater driving unit 16, and a display unit 18 for displaying the operation state of the above-described electrically insulating cooker.

3, the microprocessor 10 incorporated in the thermo-sensitive rice cooker maintains the standby state when the operation power is turned on (S301) while determining whether various cooking modes are set by key input (S302).

If it is determined in step S301 that the cooking mode has not been set, the heater driving unit 16 sets the cooking mode of the heater driving unit 16 to the cooking mode The heater, the heater for the lid and the heater for the body are operated to execute the set cooking mode (S303).

That is, in accordance with each cooking mode, the operating time and the operating temperature of the heater for the heater driving unit 16, the heater for the lid, and the heater for the lid are controlled to perform the set cooking mode to determine whether the cooking is finished (S304).

If the operation of the cooking mode is not completed, the microprocessor 10 continues to execute the cooking mode (S303). When the operation of the cooking mode is completed, the heating heater of the heater driving unit 16, (S305), and when the internal temperature of the thermosensible rice cooker sensed by the temperature sensor for cooking (S306) of the sensing unit 14 while performing the thermostat function is lower than a predetermined temperature (e.g., 75 (S307). ≪ / RTI >

As a result, if the internal temperature of the thermo-sensitive rice cooker is higher than a predetermined temperature (for example, 75 ° C), the internal temperature of the thermo-sensitive cooker is sensed again (S306) The operation of various heaters of the heater driving unit 16 is performed (S308) to raise the internal temperature of the thermo-sensitive rice cooker.

Therefore, the internal temperature of the rice cooker maintains a certain temperature (for example, 75 ° C), so that the rice stored in the rice can be kept warm.

2, when the operation mode of the thermo-sensitive cooker is set to the cooking mode, operation power is supplied to the cooking heater of the heater driving unit 16, the heater for the lid, and the heater for the body, (T1) is performed for a predetermined time (about 10 to 12 minutes) so that the internal temperature is raised to a predetermined temperature (for example, 45 Lt; 0 > C).

When the absorption process (T1) for allowing water to be absorbed into the rice is completed, a first heating process (T2) is performed in which the interior is heated to a predetermined temperature (for example, 75 DEG C) Is determined.

That is, if it takes about 2 minutes to raise the internal temperature of the thermosensitive cooker to 75 캜, it is determined that the cooked amount of the cooker is 1, and the heater is supplied to each heater in the second heating step (T 3) The amount of heat to be supplied to each heater in the second heating step (T3) and the boiling maintenance step (T4) is adjusted to 85% .

If it takes about 4 minutes, it is determined that the cooking amount is 3 servings. In the second heating step (T3) and the boiling maintenance step (T4), the amount of heat supplied to each heater is adjusted to 90% The amount of heat to be supplied to each heater in the second heating step (T3) and the boiling maintenance step (T4) is determined to be 95%, while if it takes about 6 minutes, , The amount of heat supplied to each heater in the second heating step (T3) and the boiling maintenance step (T4) is adjusted to 100%, and in the second heating step (T3), the internal temperature is raised to a predetermined temperature .

Then, the boiling maintenance step (T4) is performed in which the second heating step (T3) is extended to heat the interior and heat the interior so that the internal temperature is raised to the cooking completion temperature (for example, 125 DEG C).

After the completion of each step, the cooked rice is heated to a predetermined temperature (115 ° C) for a predetermined period of time (about 12 minutes) do.

However, the above-mentioned electric heat-insulated rice cooker has the drawback that it can not cook the rice cake because the inside temperature is set so that the rice cake does not occur during the cooking and the inside of the inner film is coated so that the rice cake is not generated.

An object of the present invention is to provide a control method of a rice cooker for an electric heat-preserving rice cooker, which is capable of adjusting the progress time and operating temperature of each cooking step of the rice cooker to be cooked in an optimal state.

In order to accomplish the above object, an embodiment of the present invention is to provide a rice cooker which comprises an absorption process for absorbing water to rice while heating the inside of the rice cooker for a predetermined time (12 minutes) at a predetermined temperature (45 ° C) A heating step of measuring a time taken to heat the inside of the rice cooker to a predetermined temperature (75 캜), determining a cooking amount based on the time, and determining a heat amount distribution; (115 DEG C) for a certain period of time (9 minutes) after the completion of the boiling and holding process, and then heating the inside of the rice cooker Is reheated at a predetermined temperature (125 DEG C) for a predetermined time (3 minutes).

Here, in another embodiment of the present invention, the absorption process, the heating process, the boiling maintenance process, and the moxibustion process are the same as those of the first embodiment, and only the reheating process differs from the first embodiment in that the inside of the rice- ), And then the reheating process is terminated.
