Abstract
본 발명은 전자렌지의 냉각팬 제어장치에 관한 것으로, 종래에는 히터 구동시 일정시간간격 및 고내온도감지에 의거하여 냉각팬을 온/오프 반복시켜 구동시키고 있으므로, 온도의 급격한 변화로 인해 조리성능이 떨어지고, 전장부품의 온도상승으로 인해 각 부품의 성능 및 신뢰성가 떨어지는 단점이 있었다. 본 발명은 냉각팬에 입력전원을 직접 인가시켜 고속회전시킬수 있는 고속구동용 릴레이와, 냉각팬에 감압소자를 감압된 전원을 인가시켜 저속회전시킬수 있는 저속구동용 릴레이와, 고내온도를 감지하여 그 감지된 온도에 따라 히터 구동시에는 상기한 냉각팬을 저속회전으로 제어하는 제어수단으로 구성된 전자렌지의 냉각팬 제어장치를 제공함으로써, 부품의 신뢰성을 높이고, 조리성능도 향상시킬 수 있게 된다.The present invention relates to a cooling fan control apparatus for a microwave oven, and in the related art, since a cooling fan is repeatedly turned on and off based on a constant time interval and sensing of an internal temperature when a heater is driven, And the performance and reliability of each part are deteriorated due to the temperature rise of the electric parts. The present invention relates to a high-speed driving relay which is capable of rotating at a high speed by directly applying an input power to a cooling fan, a low-speed driving relay which can rotate at a low speed by applying a reduced- And a control means for controlling the cooling fan to rotate at a low speed when the heater is driven according to the sensed temperature, thereby improving the reliability of the component and improving the cooking performance.
