도2는 본 발명 물통내장 냉장고 디스펜서의 외부 구성도이고, 도3은 본 발명 물통내장 냉장고 디스펜서의 내부 구성도이며, 도4는 본 발명 물통내장 냉장고 디스펜서의 동작 흐름도로서, 이에 도시한 바와 같이 사용자가 외부 물통(21)을 호스 고정체에 연결된 외부 물통 연결호스를 상기 외부 물통(21)에 넣고, 표시부(22)의 스위치(26)를 누르면 전기적 신호가 발생하며, 이 전기적 신호에 의해 상기 표시부(22)의 물없음 램프(25)가 오프되고, 직류펌프(12)가 정방향이 아닌 역방향으로 작동하여 물이 상기 외부 물통(21)에서 상기 외부 물통 연결호스를 타고 역지변(가)를 통해 냉장고 내부 물통(11)으로 흘러들어가며, 이때 역지변(나)는 상기 역지변(가)와는 반대 방향으로 설치되어 디스펜서 취출부(15)로 흐르지 않게되고, 상기 냉장고 내부 물통(11)에 물이 서서히 차서 내부 물통(11)의 상단부 수위감지 접점(23)에 다달으면 통전이 되어 상기 직류펌프(12)가 오프되며, 만약 물이 하단부 수위감지 접점(24) 이하로 떨어지면 하단부 수위감지 접점(24)에 흐르던 전류가 단전되어 표시부(22)의 물없음 램프(25)가 온되고, 또한 일정시간 내에 상기 내부 물통의 하단부 수위감지 접점(24)이 통전되지 않으면 상기 외부 물통(21)에 물이없는 것으로 판단하여 상기 표시부(22)의 물없음 램프(25)를 온시킨다.FIG. 2 is an external configuration diagram of the bucket dispenser incorporating the present invention, FIG. 3 is an internal configuration diagram of the refrigerator dispenser in the bucket of the present invention, and FIG. 4 is an operation flowchart of the refrigerator dispenser in the bucket of the present invention. When the external bucket 21 is inserted into the external bucket connecting hose connected to the hose fixing body into the external bucket 21 and the switch 26 of the display unit 22 is pressed, an electrical signal is generated. (22) the no water lamp 25 is turned off, the DC pump 12 is operated in the reverse direction rather than in the forward direction so that the water in the outer bucket 21 to the outer bucket connecting hose through the reverse side (a) It flows into the refrigerator inner bucket 11, wherein the reverse side (b) is installed in the opposite direction to the reverse side (a) so as not to flow to the dispenser outlet 15, the water in the refrigerator inside the bucket (11) Standing The DC pump 12 is turned off when the upper end water level detection contact 23 of the inner bucket 11 is charged, and if the water drops below the lower level water level contact 24, the lower level water level contact 24 is provided. If the current flowing in the power supply is cut off and the water-free lamp 25 of the display unit 22 is turned on, and the water level sensing contact 24 of the lower end of the inner bucket does not energize within a predetermined time, the outer bucket 21 has no water. It is judged that the water-free lamp 25 of the display unit 22 is turned on.

사용자가 디스펜서 누룸판(14)을 누르면 전기적 신호가 발생하고, 이 전기적 신호에 의해 직류펌프(12)가 정방향으로 동작하게 되며, 상기 직류펌프(12)에 의해 내부 물통(21)에서 물이 물통호스를 타고 상기 직류펌프(12)를 지나 역지변(나)를 통해 디스펜서 취출부로 물이 나오게 되고, 이때 역지변(가)는 상기 역지변(나)와는 반대 방향으로 설치되어 있기 때문에 물이 흐르지 않는다.When the user presses the dispenser nurum plate 14, an electrical signal is generated, and the DC pump 12 operates in the forward direction by the electrical signal, and water flows from the internal bucket 21 by the DC pump 12. Water flows through the DC pump 12 through the reverse pump (B) to the dispenser outlet, and the water flows because the reverse valve (A) is installed in the opposite direction to the reverse valve (B). Do not.

이상에서 설명한 바와 같이 본 발명 물통내장 냉장고 디스펜서 및 제어방법은 큰 비용 상승없이 자동으로 물을 공급해 줌으로써, 물통에 사용자가 물을 넣어줘야 하는 불편함이 없어지는 효과가 있다.As described above, the present invention has a bucket dispenser and a control method of the bucket, thereby automatically supplying water without a significant cost increase, thereby eliminating the inconvenience that a user must put water in the bucket.
