Abstract

본 발명은 예약취사기능을 구비한 전기밥솥에 관한 것으로서, 더욱 상세하게는 현재시각이나 예약시각에 밥을 취반할때 전기밥솥의 뚜껑이 열려 있으면 밥을 취사하지 않도록 한 밥솥뚜껑 열림시 취사 및 예약 취사 방지 방법에 관한 것으로, 종래에는 예약기능을 추가하여 예약기능에 의하면 밥을 임의의 시각에 취사할 수 있으므로 편리하나, 전술한 일반 취사시와 마찬가지로 전기 밥솥에 내장된 제어부에서는 압력감지센서에 의하여 감지된 내부케이스 내입 여부에 의해서만 취사여부를 판단하기 때문에 외부 케이스 내에 내부 케이스를 삽입한 상태에서 전기밥솥의 뚜껑을 완전히 닫지 않아도 이를 제어부에서 감지하지 못하고 선택된 동작모드로 밥을 취사하기 때문에 밥이 선택된 동작 모드에 의하여 취사되지 못하고 설익는 경우가 종종 발생한다.The present invention relates to an electric rice cooker having a reservation cooking function, and more specifically, when cooking rice at the current time or reservation time, if the lid of the rice cooker is open, cooking and reservation when the cooker lid is opened so as not to cook rice. A method of preventing cooking, in the related art, it is convenient to add a reservation function and according to the reservation function, it is convenient to cook rice at an arbitrary time. Since only cooking is judged based on whether the inner case is detected or not, even if the lid of the rice cooker is not completely closed while the inner case is inserted into the outer case, the controller does not detect this and cooks rice in the selected operation mode. Often uncooked and uncooked by the operation mode The.

본 발명은 예시도면 제4도에서와 같이 외부 케이스 저면에 설치된 압력감지센서에 의하여 내부 케이스가 안착됨을 감지하여 “하이”“로우”상태를 출력하고, 뚜껑열림감지센서에 의하여 밥솥뚜껑의 개폐상태를 감지하여 “하이”“로우”상태를 출력하며, 상기 압력감지센서와 뚜껑열림감지센서의 출력이 모두 “하이”상태이면 키조작으로 선택된 동작에 따라 취사기능을 수행하는 한편, 상기 압력감지센서와 뚜껑열림감지센서의 출력중 어느 하나라도 “로우”상태이면 키 조작으로 동작모드 키나 취사키의 입력에 대해 소정시간동안 경고음을 출력하도록 한 것이다.The present invention detects that the inner case is seated by a pressure sensor installed on the bottom of the outer case as shown in Figure 4 of the drawing, and outputs a "high" "low" state, by the lid open sensor to open and close the cooker lid Detects and outputs a "high" "low" state, and when the outputs of the pressure sensor and the lid open sensor are both "high", the cooking function is performed according to the selected operation by the key operation, and the pressure sensor If any of the outputs of the sensor and the lid open detection sensor are in the “low” state, a key operation will output a warning sound for a predetermined time for the operation mode key or the cooking key input.

Method of preventing cooking and reservation cooking when the lid of the cooker is opened.

The method of claim 1, wherein the output of the alarm sound is repeatedly output only a predetermined number of times.

Supplying the main power to maintain the rice cooker in the standby state, detecting the inner case is seated by a pressure sensor installed on the bottom of the outer case and outputting a "high" "low" state, and lid open detection Detecting the opening and closing state of the cooker lid by the sensor to output a "high" "low" state, and if the output of the pressure sensor and the lid open detection sensor is both "high" state to save the reservation environment set by the key operation And performing the cooking function in the set operation mode when the set reservation time and the current time coincide with each other. When the output of the pressure sensor and the lid open sensor is “low”, the key operation is performed. Cooker lid column, characterized in that consisting of the step of outputting a warning sound for a predetermined time for the input of the mode key or cooking key During cooking, and how to reserve catering protection.

The lid open sensor according to claim 3, wherein the lid open sensor outputs a high state when the lid is closed on the rice cooker and outputs a low state when the lid is open from the rice cooker body. How to avoid cooking and booking catering.
