이하 본 발명에 따른 전기보온밥솥의 제어방법에 대해 상세하게 살펴보면 다음과 같다.Looking in detail with respect to the control method of the electric thermal rice cooker according to the present invention.

도 1은 본 발명에 따른 전기보온밥솥의 구동을 제어하기 위한 제어구성도이다.1 is a control block diagram for controlling the driving of the electric thermal rice cooker according to the present invention.

도시되고 있는 본 발명의 제어구성은, 제품으로 전원을 공급하는 전원공급부(50), 불림, 취사, 보온 등의 조리신호를 입력하기 위한 신호입력부(60), 사용자가 입력한 조리신호를 출력하는 디스플레이부(20), 밥솥바닥의 온도를 감지하는 온도감지부(10), 불림, 취사, 보온기능을 수행되도록 작동하는 기능작동부(40), 불림, 취사, 보온 기능이 수행되도록 제어하는 마이크로컨트롤러(30)를 포함하여 구성된다.The control configuration of the present invention is shown, the power supply unit 50 for supplying power to the product, the signal input unit 60 for inputting cooking signals such as soaking, cooking, warming, etc., and outputs the cooking signal input by the user Display unit 20, temperature sensing unit 10 for sensing the temperature of the rice cooker bottom, function operation unit 40 to operate soaking, cooking, warming function, microcontrolling to perform soaking, cooking, warming function is performed It is configured to include a controller (30).

상기 기능동작부(40)는 밥솥 내의 쌀이 불림, 취사, 보온되도록 솥의 내부를 가열하기 위한 구성이다. 이를 위해서 히터 등과 같은 가열수단이 포함된다.The functional operation unit 40 is configured to heat the inside of the pot so that rice in the cooker is soaked, cooked, and warmed. For this purpose, a heating means such as a heater is included.

상기 온도감지부(10)는 내솥 바닥의 온도를 감지하기 위한 구성으로, 상기 온도감지부(10)를 통해서 전달된 온도신호는 마이크로컨트롤러(30)에 전달된다. 상기 온도감지부(10)를 통해서 감지된 온도에 따라 취사의 진행정도, 보온온도 등이 판단되고, 판단된 온도정보에 의해서 내솥의 온도가 제어된다.The temperature sensing unit 10 is configured to sense the temperature of the bottom of the inner pot, and the temperature signal transmitted through the temperature sensing unit 10 is transmitted to the microcontroller 30. According to the temperature sensed by the temperature sensing unit 10, the degree of cooking, the warming temperature, and the like are determined, and the temperature of the inner pot is controlled by the determined temperature information.

상기 마이크로컨트롤러(30)는 불림, 취사, 보온 등의 조리신호에 따라 내솥에 출력되는 가열에너지를 조절한다. 이를 위해서 내솥에 출력되는 가열에너지의 양을 각기 달리 제어하는 알고리즘을 적용한다.The microcontroller 30 adjusts heating energy output to the inner pot according to cooking signals such as soaking, cooking, and keeping warm. To this end, different algorithms for controlling the amount of heating energy output to the inner pot are applied.

즉, 단순히 취사기능을 위해서 솥을 가열하는 가열에너지의 출력과정을 제 1 알고리즘이라 정의하고, 불림기능과 취사기능을 함께 수행하기 위해서, 불림기능 선택에 따라 일정시간 간격으로 전원의 인가/차단을 소정시간동안 반복적으로 수행하고, 취사를 수행하기 위해서 솥을 가열하는 가열에너지의 출력과정을 제 2 알고리즘이라 정의한다.That is, the output process of the heating energy for heating the pot simply for the cooking function is defined as the first algorithm, and in order to perform the soaking function and the cooking function together, the application of the power supply is performed at regular intervals according to the soaking function selection. A second algorithm is defined as an output process of heating energy for repeatedly performing a predetermined time and heating the pot in order to perform cooking.

도 2는 본 발명에 따른 전기보온밥솥이 구동제어되는 동작제어흐름도이다.2 is an operation control flow chart of the electric thermal rice cooker driving control according to the present invention.

쌀을 취사하기 위해서, 신호입력부(60)를 통해서 조리신호를 입력한다. 신호입력부(60)를 통해서 입력된 조리신호는 마이크로컨트롤러(30)에 전달된다. 상기 마이크로컨트롤러(30)는 입력된 조리신호에 따라 밥솥 내부에 있는 밥의 상태가 달라지도록 가열한다. 즉, 사용자가 불림기능을 선택하면, 일정시간동안 쌀을 불리고 난 후 취사기능이 수행된다. 그러나 사용자가 단순히 취사기능만 선택하면, 전원이 인가되고 조리신호를 입력함과 동시에 취사를 위한 가열에너지가 솥 내부에 출력된다.In order to cook rice, a cooking signal is input through the signal input unit 60. The cooking signal input through the signal input unit 60 is transmitted to the microcontroller 30. The microcontroller 30 is heated to change the state of the rice in the cooker according to the input cooking signal. That is, when the user selects the soaking function, the cooking function is performed after brewing rice for a predetermined time. However, if the user simply selects the cooking function, the power is applied and inputs a cooking signal and heating energy for cooking is output inside the pot.

이하 쌀을 불려 취사하기까지의 과정을 좀 더 상세하게 살펴보면 다음과 같다.Hereinafter, the process of cooking rice is cooked in more detail as follows.

즉 도 2에 도시되고 있는 바와 같이, 본 발명은 사용자가 씻은 쌀을 바로 밥솥에 넣고 불림기능을 선택한다(제 200 단계). 그리고 쌀을 불려 밥을 지을 경우, 사용자의 취향에 따라 불림기능을 얼마동안 수행할 것인지 불림시간을 조정한다(제 210 단계). 그리고 나서 취사키를 입력하고(제 220 단계), 입력한 취사기능신호는 마이크로컨트롤러(30)에 전달된다.That is, as shown in Figure 2, the present invention puts the washed rice directly into the rice cooker to select the soaking function (step 200). When the rice is called and cooked, the soaking time is adjusted for how long the soaking function will be performed according to the user's preference (step 210). Then, the cooking key is input (step 220), and the input cooking function signal is transmitted to the microcontroller 30.

이와 같이 불림/취사신호가 입력됨에 따라, 상기 마이크로컨트롤러(30)는 불림기능이 사용자에 의해서 선택되었는지 판단하게 된다(제 230 단계).As the call / cook signal is input as described above, the microcontroller 30 determines whether the call function is selected by the user (step 230).

상기 제 230 단계에서 마이크로컨트롤러(30)의 판단에 따라, 불림기능이 선택되지 않았다고 판단되면, 단순히 취사기능을 수행하기 위해서 제 1 알고리즘에따른 가열에너지가 출력된다(제 240 단계). 따라서 제 1 알고리즘을 통해서 단순히 취사를 위한 가열을 진행함에 따라, 쌀이 불려지는 시간여유 없이 즉시 가열된다.If it is determined in step 230 that the soaking function is not selected according to the determination of the microcontroller 30, heating energy according to the first algorithm is simply output to perform the cooking function (step 240). Therefore, as the heating proceeds simply for cooking through the first algorithm, the rice is immediately heated without any time for soaking.

한편, 상기 제 230 단계에서 상기 마이크로컨트롤러(30)의 판단에 따라, 취사기능과 더불어 불림기능이 선택되었다고 판단되면, 쌀을 불린 후 취사하기 위해서 제 2 알고리즘에 따른 가열에너지가 출력된다(제 250 단계).On the other hand, when it is determined in step 230 that the soaking function is selected together with the cooking function according to the determination of the microcontroller 30, heating energy according to the second algorithm is output in order to soak and cook rice (250). step).

이에 따라 우선 소정시간동안 일정시간간격으로 전원의 인가/차단동작을 소정시간동안 반복한다. 그리고 난 후, 사용자가 지정한 불림시간에 도달하였다고 판단하면, 마이크로컨트롤러(30)는 취사가 진행되도록 솥을 가열하기 위한 가열에너지의 출력을 제어한다.Accordingly, first, the power supply / blocking operation is repeated for a predetermined time for a predetermined time. Then, when it is determined that the user's designated soak time has been reached, the microcontroller 30 controls the output of heating energy for heating the pot so that cooking is performed.

이와 같이 본 발명은, 쌀을 씻은 후 별도로 쌀을 불리지 않고도 솥을 가열하는 내부 알고리즘으로 인해서, 솥에 있는 쌀이 자동으로 불림기능이 수행되도록 제어하는 기능이 포함된다. 이에 따라 사용자는 별도로 쌀을 불리는 작업을 하지 않고도 자동으로 밥솥의 내부알고리즘으로 쌀을 불린 후 취사를 진행시킴으로서, 사용자가 원하는 취향에 따라 밥을 지을 수 있다.As such, the present invention includes a function of controlling the rice in the pot to be automatically called due to the internal algorithm of heating the pot without washing the rice separately after washing the rice. Accordingly, the user automatically cooks the rice by calling the rice with the internal algorithm of the rice cooker without performing a work called rice separately, so that the user can cook rice according to the desired taste.

이상 살펴본 바와 같이 본 발명은 불림기능 및 불림시간을 선택하여, 일정시간동안 불림기능을 수행한 후 취사되도록 제어하는 것을 기본적인 기술적 사상으로 한다.As described above, the present invention has a basic technical concept of selecting a soaking function and a soaking time and controlling the cooking after performing the soaking function for a predetermined time.

본 발명의 권리는 위에서 설명된 실시예에 한정하지 않고 청구범위에 기재된 바에 의해 정의되며, 본 발명의 분야에서 통상의 지식을 가진 자가 청구범위에 기재된 권리범위 내에서 다양한 변형과 개작을 할 수 있다는 것은 자명하다.The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

따라서 본 발명에 따른 전기보온밥솥의 제어방법으로 인해서 다음과 같은 효과를 기대할 수 있다.Therefore, due to the control method of the electric rice cooker according to the present invention can be expected the following effects.

종래와 같이 수작업으로 쌀을 불린 후 취사하는 번거로움에서 벗어나, 쌀을 씻은 후 바로 밥솥에 넣어도, 적정시간동안 불림기능을 수행한 후 취사되도록 가열에너지를 솥 내부에 출력한다.As in the prior art, the rice is manually blown out of the hassle of cooking, even after washing the rice and put it in the rice cooker immediately, after performing the soaking function for a suitable time, the heating energy is output to the inside of the cooking pot.

이로 인해서 본 발명은 편리하게 쌀을 불린 후 취사가 가능하도록 제어함으로서, 소비자의 취향에 따른 다양한 상태의 밥을 제공할 수 있어, 본 발명에 따른 제품을 사용하는 사용자는 제품에 대한 만족감을 극대화시킬 수 있다.Due to this, the present invention can conveniently provide rice cooked after controlling the rice, and can provide rice in various states according to the taste of the consumer, so that the user using the product according to the present invention can maximize the satisfaction with the product. Can be.
