Claims (1)

캐비티(3)의 공기흡기구(14)와 공기 배기구(15)에 내장된 흡기구 온도센서(l)와 배기구 온도센서(2)의 출력신호를 전압으로 변환시키는 신호처리부(4)와, 상기 신호처리부(4)로 부터 출력된 신호를 디지탈로 변환시켜 온도데이타를 지정 램에 저장하고, 비교하는 마이컴(5)과, 그 마이컴(5)의 제어신호에 따라 릴레이를 제어하며 메인전압을 조정하는 릴레이제어부(6)와 표시부(8)로 구성되어 있는 전자조리기의 안전시스템에 있어서, 상기 흡기구센서(1)와 배기구센서(2)의 현 온도데이타값(Ui)(Vi)을 마이컴(5)이 8초 주기로 읽어들여 지정램에 저장하고, 흡기구센서의 초기온도값(Uo) 에 온도상수(Tc)를 가산한 데이타값(Tm)과, 흡기구센서의 초기온도값(Uo)에 온도상수(TD)를 가산한 데이타값(Tn)을 계산한 후 이 데이타값(Tm)과 현 배기구센서의 온도데이타값(Vi)을 비교하여 현 배기구센서의 온도데이타값(Vi)이 크면 핫 플래그를 세트시키고, 마이컴(5)의 출력포트(C)(D)를 리세트시킨 후표시부(8)에 "HOT"글자를 디스플레이시키며, 현 배기구센서의 온도데이타값(Vi)이 데이타값(Tm)보다 작고 핫 플래그가 세트되어 있지 않으면 전자조리기를 수행하고, 현 배기구 센서의 온도데이타값(Vi)이 데이타값(Tm)보다 작고 핫 플래그가 세트되어 있으며 흡기구센서의 초기온도값(Uo)에 온도상수(TD)를 더한 데이타값(Tn)과, 현 배기구센서의 온도데이타값(Vi)을 비교하여 현 배기구센서의 오너도데이타(Vi)이 크면 "핫플래그"를 세트시키고, 메인전원을 오프시킨 후 "HOT" 이란 글자의 데이타를 표시부에 디스플레이 시키는 것을 특징으로 한 전자조리기의 안전시스템.A signal processor (4) for converting the output signal of the intake port temperature sensor (1) and the exhaust port temperature sensor (2) incorporated in the air intake port (14) and the air exhaust port (15) of the cavity (3) into a voltage; A relay that converts the signal output from (4) into digital and stores the temperature data in the designated RAM, compares the microcomputer 5 to compare with the control signal of the microcomputer 5, and adjusts the main voltage. In the safety system of an electronic cooker composed of the control unit 6 and the display unit 8, the microcomputer 5 converts the current temperature data values Ui (Vi) of the intake sensor 1 and the exhaust port sensor 2. The data is read every 8 seconds and stored in the designated RAM, and the data value Tm is obtained by adding the temperature constant Tc to the initial temperature value Uo of the intake sensor and the temperature constant T to the initial temperature value Uo of the intake sensor. Calculate the data value (Tn) plus D ), then compare this data value (Tm) with the temperature data value (Vi) of the current exhaust sensor. On the other hand, if the temperature data value Vi of the current exhaust port sensor is large, the hot flag is set, the output port C of the microcomputer 5 is reset, and then the " HOT " If the temperature data value (Vi) of the current exhaust port sensor is smaller than the data value (Tm) and the hot flag is not set, the electronic cooker is carried out, and the temperature data value (Vi) of the current exhaust port sensor is smaller than the data value (Tm). The hot flag is set and the owner of the current exhaust port sensor is compared with the data value (Tn) obtained by adding the temperature constant (T D ) to the initial temperature value (Uo) of the intake sensor and the temperature data value (Vi) of the current exhaust port sensor. If the data (Vi) is large, set the "hot flag", turn off the main power supply, and then display the data of the word "HOT" on the display. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
