Abstract

본 발명은 냉장고 도어의 과적상태를 자동 체크하여 이를 사용자에게 청각적으로 경고할 수 있도록 한 냉장고 도어의 과적 경고장치에 관한 것으로, 이를 위하여 본 발명은, 냉장고의 본체 상단부와 냉장고 도어의 상단부에 사이에 고착되어 그의 내측면에 일정 간격을 가지고 다수개 설치된 수납선반을 갖는 도어에서의 음식물과적으로 인한 도어의 아래 방향으로의 치우침을 감지하는 수단; 감지수단에서 감지된 감지신호를 검출하여 소정 레벨의 DC 전압으로 변환하는 센서; 이 센서의 출력측에 연결되며, 센서로부터의 출력 DC 전압에 의해 턴온 또는 턴오프 제어되어 외부 전원전압의 공급을 절환하는 스위칭 수단; 냉장고 도어의 과적 발생시에, 스위칭 수단의 절환에 기초하여 공급되는 외부 전원전압에 의해 선택적으로 작동되어 청각적인 경고음을 단속 또는 연속적으로 발생하는 알람구동부를 포함한다.The present invention relates to an overload warning device for a refrigerator door that automatically checks an overload state of a refrigerator door and alerts the user acoustically. To this end, the present invention provides a device between an upper end of a main body of a refrigerator and an upper end of a refrigerator door. Means for detecting a bias in the downward direction of the door caused by food and food in the door having a plurality of storage shelves installed at a predetermined distance on the inner side thereof and fixed to the inner side; A sensor for detecting a detection signal sensed by the detection means and converting the detected signal into a DC voltage of a predetermined level; Switching means connected to an output side of the sensor and controlled to be turned on or off by an output DC voltage from the sensor to switch supply of an external power supply voltage; In the event of an overload of the refrigerator door, the alarm driver may be selectively operated by an external power supply voltage supplied based on the switching of the switching means to intermittently or continuously generate an audible warning sound.

따라서, 냉장고 도어의 과적을 청각적으로 자동 경고하는 본 발명은 냉장고 도어의 빈번한 과적으로 인해 야기될 수 있는 냉장고의 수명단축 및 불필요한 전력소모를 효과적으로 방지할 수 있는 것이다.Therefore, the present invention, which is audible and automatic warning of the overload of the refrigerator door, can effectively prevent the shortening of the life of the refrigerator and unnecessary power consumption which can be caused by frequent overload of the refrigerator door.
