Abstract

본 발명은 온도센서로 가열실의 흡기구 및 배기구의 온도를 검출하면서 가열시간을 설정하여 음식물을 자동으로 가열 및 조리하는 것으로서 종래에는 가열실의 흡기구에 설치된 온도센서가 검출하는 대기온도에 따라 보상온도증가분을 설정하여 음식물을 가열하였으므로 음식물의 연속조리시 흡입구의 온도가 실제의 대기 온도보다 일정 온도오차만큼 높은 값으로 보상온도증가분을 설정하고, 이 보상온도증가분을 이용하여 1차가열 및 추가가열을 수행하여 음식물의 전체 가열시간이 증가하게 되고, 이로 인하여 음식물이 과도하게 가열되어 음식물의 조리성능이 악화됨은 물론 필요없이 많은 전력이 소모되었다.The present invention is to automatically heat and cook food by setting the heating time while detecting the temperature of the inlet and exhaust ports of the heating chamber with a temperature sensor. Conventionally, the compensation temperature according to the atmospheric temperature detected by the temperature sensor installed in the inlet of the heating chamber. Since the food is heated by setting the increase, the compensation temperature increase is set so that the temperature of the intake port is higher than the actual atmospheric temperature by a certain temperature error during continuous cooking of the food, and the primary and additional heating are performed using the compensation temperature increase. The total heating time of the food is increased, and thus, the food is excessively heated, and the cooking performance of the food is deteriorated.

본 발명은 음식물의 가열동작을 시작하는 초기의 흡기구의 온도변화와, 흡기구의 온도 및 실제의 대기온도간의 온도오차가 밀접한 관계를 갖는 것을 이용하여 대기온도를 정확히 인식하는 것으로 팬모타를 구동시키기 전의 흡기구의 온도와 설정시간동안 팬모타를 구동시ㅋ 가열실의 온도가 평형을 이루도록 한 후의 흡기구의 온도를 검출항 두 흡기구의 온도간의 온도변화를 구하고, 그 온도변화에 해당되는 흡기의 온도 및 실제의 대기온도와의 온도오차를 설정 즉, 흡기구의 온도변화값에 따라서 실험적으로 미리 설정한 흡기구의 온도 및 실제 대기온도의 온도오차를 설정하여 대기온도를 정확히 인식하고, 인식한 대기온도에 따라 보상온도증가분 및 추가가열시간을 설정하여 음식물을 가열함으로써 음식물에 따라 최적으로 보상온도증가분을 설정항 음식물의 조리성능을 향상시킬 수 있다.The present invention accurately recognizes the air temperature by using a close relationship between the temperature change of the intake port at the beginning of the heating operation of food and the temperature error between the temperature of the intake port and the actual air temperature before the fan motor is driven. Drive the fan motor for the intake temperature and set time. Detect the temperature of the intake port after the heating chamber is in equilibrium. Find the temperature change between the temperatures of the two intake ports. Set the temperature error with the air temperature of the air inlet, that is, by setting the temperature of the inlet and the actual air temperature in advance according to the temperature change value of the inlet, the air temperature is correctly recognized and compensated according to the recognized air temperature. Set the temperature increase and additional heating time to heat the food to optimally compensate the increase in temperature according to the food. It can improve the performance of jeonghang cooked food.
