Description

냉장고의 베터리 충전장치.Battery charger in the refrigerator.

본 발명은 냉장고의 베터리 충전장치에 관한 것으로서, 특히 별도의 전원 공급부의 필요 없이도 냉장고의 전원부에서 인가된 전력으로 쉽게 2차 전지를 충전할 수 있도록 하는 냉장고의 베터리 충전장치에 관한 것이다.The present invention relates to a battery charging device of a refrigerator, and more particularly, to a battery charging device of a refrigerator which enables the secondary battery to be easily charged with the power applied from the power supply unit of the refrigerator without the need for a separate power supply unit.

일반적으로 전지는 전기력 혹은 전압의 중요한 원천으로 두 종류가 있다.In general, there are two kinds of batteries as important sources of electric force or voltage.

하나는 일차전지로 원물질이 사용되어 없어지면, 그 유용 수명이 끊어져 버리는 것으로 건전지라고 한다.One is called a battery, when the raw material is used as a primary battery, its useful life is lost.

다른 하나는 2차 전지 혹은 축전지로서 그 자체의 원 전류량을 소모해 버린 다음 반대 방향으로 전류를 통하게 외부에서 재충전함으로써 복귀되는 것이다.The other is a secondary battery or accumulator that consumes its original amount of current and then returns by recharging externally with current in the opposite direction.

이러한 2차 전지를 충전하기 위한 충전기의 경우 아답터와 충전기를 동시에 사용하여 충전하는 방식이 사용되고 있다.In the case of a charger for charging the secondary battery, a charging method using an adapter and a charger at the same time is used.

그런데, 이러한 방식은 아답터와 충전기를 동시에 구비하여야 하므로 부피가 커져 불편을 초래하게 된다.By the way, this method has to be equipped with an adapter and a charger at the same time, resulting in a bulky inconvenience.

또한, 2차 전지 내부에 전원이 무리하게 공급될 경우, 2차 전지의 수명저하 현상을 초래하게 되는 문제점이 있다.In addition, when the power is excessively supplied inside the secondary battery, there is a problem that causes the life of the secondary battery.

한편, 2차 전지에 과다한 전원이 공급되는 것을 방지하기 위해 내부 전원을 마이크로 컨트롤러를 사용하여 제어함으로써 2차 전지를 충전하는 방식이 있다.On the other hand, there is a method for charging the secondary battery by controlling the internal power supply using a microcontroller to prevent excessive power supply to the secondary battery.

그런데, 이러한 방식은 회로가 복잡하고, 마이크로 컨트롤러를 사용함으로써 가격이 상승하게 되는 문제점이 있다.However, this method has a problem that the circuit is complicated and the price is increased by using the microcontroller.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 별도의 충전기를 사용하지 않고도 냉장고의 일측면에 부착되어 냉장고 전원을 이용하여 2차 전지를 충전시킴으로써, 쉽게 충전이 가능하도록 하는 냉장고의 베터리 충전장치를 제공하는데 그 목적이 있다.The present invention was created to solve the above problems, and is attached to one side of the refrigerator without using a separate charger to charge the secondary battery using the refrigerator power, so that the battery of the refrigerator can be easily charged The purpose is to provide a charging device.

도2는 본 발명의 바람직한 실시예에 따른 플로우 차트이다.2 is a flow chart according to a preferred embodiment of the present invention.
