본 발명은 제빙기용 드레인 펌프 유닛에 관한 것으로, 보다 상세하게는, 워터박스 내의 드레인 펌프가 고장났거나 배수구가 막혀 물이 안전수위에 도달하면 제빙기의 전체 전기를 차단할 수 있도록 한 제빙기용 드레인 펌프 유닛에 관한 것이다. The present invention relates to a drain pump unit for an ice maker, and more particularly, a drain pump unit for an ice maker to cut off the entire electricity of the ice maker when the drain pump in the water box is broken or the drain is blocked and the water reaches the safety level. It is about.

일반적으로 제빙기는 저수조에서 공급된 물을 냉각시스템이 마련된 제빙장치에 의해 물을 순환시켜 얼음 모양의 증발기 표면에 물을 흡착시켜 얼음을 생성하는 것으로서, 제빙기는 케이스와, 도어부와, 제빙유닛과, 냉각 시스템 그리고, 저수조를 포함한다.In general, an ice maker circulates water supplied from a water tank by an ice maker equipped with a cooling system to adsorb water onto an ice evaporator surface to generate ice. The ice maker includes a case, a door part, an ice maker unit, , Cooling systems, and reservoirs.

케이스는 일측에 개구를 형성하여 도어부에 의해 개폐되고, 케이스의 내부에는 제빙수를 결빙시켜 얼음을 형성하는 제빙유닛(얼음 모양의 증발기)과 제빙유닛에서 형성된 얼음을 저장하기 위한 얼음저장고가 구비되며, 제빙유닛과 연결되며 압축기와 응축기를 포함하는 냉각시스템이 설치된다. 그리고, 케이스에는 제빙수를 제빙유닛으로 공급하기 위한 급수관이 설치되어 내부에 소정량의 제빙수가 저장되는 저수조와 제빙유닛을 연결하여 구성된다.The case has an opening at one side thereof, and is opened and closed by a door part. An inside of the case includes an ice making unit (ice-shaped evaporator) for forming ice by freezing ice ice and an ice storage for storing ice formed in the ice making unit. It is connected to the ice making unit and a cooling system including a compressor and a condenser is installed. In addition, the case is provided with a water supply pipe for supplying the ice-making water to the ice-making unit is configured by connecting the water storage tank and the ice-making unit in which a predetermined amount of ice-making water is stored.

이러한 구성에 의해 제빙기는 내부에 위치된 제빙용 순환펌프에 의해서 저수조의 물을 얼음모양의 증발기 표면에 분사시켜 얼음을 생성하고, 생성된 얼음은 케이스 내부의 얼음저장고에 저장되어 필요에 따라 도어부를 개방하여 꺼내어 사용할 수 있다.With this configuration, the ice maker injects water from the reservoir into the ice-shaped evaporator surface by using an ice-making circulation pump located therein to generate ice, and the generated ice is stored in an ice reservoir inside the case to store the door part as necessary. It can be opened and used out.

그런데 이러한 종래의 제빙기는 작동을 중지시키거나 작동중이라도 얼음저장고에 있는 얼음이 자연적으로 녹아 녹은 물이 배수되고, 또한 제빙 과정 중에 외부 공급수가 저수조에 보충되면 기존의 녹은 물과 희석되어 사용되고 남은 물이 배수된다.However, even when the ice maker is stopped or operated, the ice in the ice reservoir naturally melts and the melted water is drained, and when the external supply water is replenished into the reservoir during the ice making process, it is diluted with the existing melted water and the remaining water is used. Drained.

이와 같이 배수되는 물을 배수구를 통해 배수시키게 되는바, 배수구가 없는 장소에 이 제빙기를 설치할 수 없기 때문에 배수되는 물을 한 곳에 모아 두었다가 일정량 모이게 되면 물을 강제로 배수시키기 위해 강제 배수 장치인 드레인 펌프가 필요하게 되는 것이다. Since the drained water is drained through the drain, it is impossible to install the ice maker in a place without the drain, so when the drained water is collected in one place and collected in a certain amount, the drain pump, which is a forced drainage system, is forcibly drained.

First, water supplied from the water supply pipe is introduced into the water box 10 through the water supply port 31 to be filled. When the water is gradually filled, the water level is increased, so that the float 63 rises along the body 61 of the floating device by buoyancy, and as such, the float 63 is wound around the inner magnet of the float 63 and the outer circumferential surface of the body 61. It comes into contact with the low water level reed switch 64. Then, when the water is further filled and the float 63 rises, the inner magnet of the float 63 and the high water level reed switch 65 come into contact with each other. As described above, the magnet and the high level reed switch 65 are switched by contact to apply driving power to the drain pump 20 from the circuit board 50. The drain pump 20 operates by applying the driving power to drain the water in the water box 10 through the drain hole 32.

상기 드레인 펌프(20)는 물의 수위가 저수위가 될 때까지 작동하게 되는데, 그것은 드레인 펌프(20)가 물을 펌핑하여 상기 플로트(63)가 몸체(61)를 따라 하강하여 저수위용 리드스위치(64)와 접촉되면, 그 접촉을 감지하는 회로기판(50)에서 드레인 펌프(20)의 구동 전원을 차단하게 된다.The drain pump 20 is operated until the water level becomes a low level, which is the drain pump 20 pumps the water so that the float 63 is lowered along the body 61, the low level reed switch 64 ), The driving power of the drain pump 20 is cut off from the circuit board 50 sensing the contact.

이와 같이 회로기판(50)의 제어에 의해 구동되는 드레인 펌프(20)가 고장나 워터박스(10) 내의 물을 배수시키기 못하는 경우나, 배수구(32)가 막힐 경우, 물의 수위가 최고점, 즉 상기 플로트(63)가 안전수위용 리드스위치(66)와 접촉되면, 회로기판(50)의 고용량 접점스위치(51)는 도시되지 않은 마이컴으로 신호를 송신하여 제빙기 전체의 작동을 정지시키게 된다. As such, when the drain pump 20 driven by the control of the circuit board 50 fails and fails to drain the water in the water box 10, or when the drain hole 32 is blocked, the water level is the highest point, that is, the When the float 63 contacts the safety level reed switch 66, the high capacity contact switch 51 of the circuit board 50 transmits a signal to a microcomputer (not shown) to stop the operation of the entire ice maker.
