Abstract

본 발명은 전자렌지 도어의 증기맺힘 방지장치 및 방법에 관한 것으로, 가열실의 온도가 상승하게 되면 가열실내의 가열물에서 발생되는 증기가 프레임의 유리면에 이슬의 형태로 맺히게 됨으로 사용자는 가열실내 가열물의 가열 진행정도를 확인할 수 없었다.The present invention relates to an apparatus and method for preventing steam condensation in a microwave oven door. When the temperature of the heating chamber is increased, steam generated from the heating material in the heating chamber is formed in the form of dew on the glass surface of the frame. The heating progress of the water could not be confirmed.

따라서 본 발명은 가열물의 종류 및 시간과 가열종류에 따라 기 설정된 가열 기준시간을 초과하여 끊는점에 도달함에 따라 가열실내의 증기가 포화되었음을 배출구의 일측에 구성 설치하여 증기의 량을 감지하기 위한 센서의 출력으로부터 판단하여 증기가 포화됨에 따라 도어 프레임의 유리면에 발생되는 이슬을 증발시켜 제거할 수 있도록 한 것으로서, 사용자는 가열실내의 가열물의 상태를 확인할 수 있도록 하였으며, 비교적 긴 시간동안 요리되어지는 음식물의 끊는점이 발생했을 경우인 증기의 포화점에서 본 발명이 동작하도록 하여 전력의 절전효과도 있다.Therefore, the present invention is a sensor for detecting the amount of steam by installing on one side of the outlet that the steam in the heating chamber is saturated as reaching the breaking point exceeding the preset heating reference time according to the type and time of heating and heating type As the steam is saturated, the dew generated on the glass surface of the door frame can be removed by evaporation. The user can check the state of the heating material in the heating chamber, and the food cooked for a relatively long time. The present invention operates at the saturation point of steam, which is the case where the break point occurs, which also saves power.

Claims

A sensor for detecting the amount of steam generated inside the heating chamber, a sensor signal processing unit for converting the signal output from the sensor into an electrical signal, and vapor condensation prevention to remove the dew condensed by saturated steam installed on the glass surface And a constant voltage unit for applying a constant voltage to the vapor condensation preventing unit, a power driving unit for switching the supply power of the constant voltage unit, and controlling the overall operation and simultaneously detecting the amount of steam in the heating chamber by the sensor signal processing unit. Condensation prevention device of the microwave door, characterized in that it comprises a control means for controlling the power drive unit.

The user inserts the heating water and starts the cooking by selecting the selection key of the control panel according to the heating material type and the heating type, and detecting the amount of steam in the heating chamber and comparing the preset value to determine whether the steam is saturated. And, if it is determined that the steam in the heating chamber is saturated, it is determined that steam begins to form on the glass surface of the door frame, and drives the steam condensation preventing unit.
