Abstract

본 발명은 물통이 하부에 설치되는 자동판매기에 있어서, 물통에 물이 있음에도 이를 감지하지 못하여 생기는 불리한 현상은 제거하도록한 자동판매기의 물통 급수 제어방법에 관한 것으로, 저수통으로부터 두개의 물통안으로 투입되는 호수의 분기점에 삼방밸브를 설치한 자동판매기의 물통사용 제어방법으로서, 저수통의 물이 하한점에 이르렀는가를 판단하는 단계와, 상기 저수통의 물이 하한점에 이르르면 펌프를 구동시키는 단계와, 상기 펌프구동후 저수통의 물이 상한점에 도달했는가를 판단하는 단계와, 상기 저수롱의 물이 상한점에 도달되지 아니하면 삼방밸브를 구동시켜 다른쪽 물통의 물이 상한점에 도달되지 아니하면 삼방밸브를 구동시켜 다른쪽 물통의 물이 이용되도록 하는 단계와, 상기 삼방밸브 구동후에도 저수통의 물이 상한점에 이르지 아니하면 펌프를 소정횟수동안 간헐적으로 구동시키는 단계와, 상기 펌프의 간헐적인 구동이후에도 저수통의 물이 상한점에 이르지 아니하면 물이 없음을 인식하고 판매중기신호를 출력하는 단계를 구비하여 특징을 가지고 있다.The present invention relates to a bucket water supply control method of the vending machine to remove the adverse phenomenon caused by not detecting even if there is water in the vending machine installed in the bottom of the bucket, which is introduced into the two buckets from the reservoir. A control method of using a bucket of a vending machine having a three-way valve installed at a branching point of a lake, the method comprising: determining whether the water in the reservoir reaches the lower limit, and driving the pump when the water in the reservoir reaches the lower limit. And determining whether the water in the reservoir reaches the upper limit after the pump is driven, and if the water in the reservoir does not reach the upper limit, the three-way valve is driven to reach the upper limit. If not, drive the three-way valve so that the water in the other bucket is used, and the water in the reservoir is the upper limit after the three-way valve is driven. If not, intermittently driving the pump for a predetermined number of times; and if the water in the reservoir does not reach the upper limit after intermittent driving of the pump, recognizing that there is no water and outputting a mid-term signal.

Claims

A method of controlling the use of a bucket in a vending machine having a three-way valve installed at a branch point of a lake introduced into two buckets from a reservoir, the method comprising: judging whether the water in the reservoir has reached a lower limit; At the point of operation, driving the pump; determining whether the water in the reservoir reaches the upper limit after driving the pump; and driving the three-way valve if the water in the reservoir does not reach the upper limit. Allowing water to be used in the water tank; driving the pump intermittently for a predetermined number of times if the water in the reservoir does not reach the upper limit after the three-way valve is driven; and even after the pump is intermittently driven. Recognizing that there is no water if the upper limit is not reached, and outputting a stop signal for the bucket of the vending machine, characterized in that Usage control method.
