PROBLEM TO BE SOLVED: To provide a two-stage distance sensing type water supply method.SOLUTION: A two-stage distance sensing type water supply method includes a process of supplying water to a water supply port when a sensing signal becomes an ON signal when a sensor senses an appearance of a foreign object at a first distance, a process of finishing water supply to the water supply port when the sensing signal becomes an OFF signal when the sensor senses a disappearance of the foreign object at the first distance, a process in which a second distance is not equal to the first distance by supplying the water to the water supply port when the sensing signal becomes the ON signal when the sensor senses the appearance and the disappearance of the foreign object at the second distance in the first place and a process of finishing the water supply to the water supply port when the sensing signal becomes the OFF signal when the sensor senses the appearance and the disappearance of the foreign object at the second distance in the second time.SELECTED DRAWING: Figure 1 |
