Abstract

본 발명은 물탱크내의 물의 잔량을 감지하여 소정단계별로 표시해 주며, 물보충시기를 경보해 줄수 있는 커피자동판매기의 물탱크 단수감지 및 표시장치에 관한 것이다.The present invention relates to a water tank stage detection and display device of the coffee vending machine that detects the remaining amount of water in the water tank and displays it for each predetermined step and can alert the water replenishment time.

종래의 커피자동 판매기는 물탱크내의 물의 잔량을 감지하여 물보충시기를 외부로 알려줄 수 있는 수단이 구비되어 있지 못하기 때문에 물탱크 단수로 인한 판매중지 상태가 종종 발생하게 되는 폐단이 있다.Conventional coffee vending machines have a discontinuity in which a discontinued condition often occurs due to the number of water tanks because the coffee vending machine does not have a means for detecting the remaining amount of water in the water tank to inform the water replenishment time to the outside.

본 발명의 장치에 의하면, 물탱크의 바닥면에 설치된 부하센서를 통해 물탱크내의 물의 잔량을 감지하고, 감지된 물의 잔량에 따라 “정상”, “물보충”, 그리고 “품절”의 단계별로 표시해 줌으로서 물탱크의 물보충시기를 사전에 알 수 있다.According to the device of the present invention, through the load sensor installed on the bottom surface of the water tank to detect the remaining amount of water in the water tank, according to the detected water remaining amount of "normal", "water replenishment" and "sold out" step by step By zooming, you can know in advance when the water tank will be refilled.

또한, 경보기를 통해 물보충시기, 즉 단수를 예고해 줌으로서 품절로 인한 판매 중지상태를 사전에 예방할 수 있다.In addition, by alerting the water replenishment time, that is, the number of steps through the alarm can be prevented in advance due to sold out.
