制御回路を設けたことを特徴とする歯科ユニットの給水
制御装置。In a dental unit that includes a pot for patients to gargle with and its saucer, a bee for receiving waste water discharged by the patient, and a clean water supply source for supplying clean water for washing the bee, the above-mentioned cot is provided. A sensor is installed, which is made of metal and uses the saucer, which is electrically insulated from the tip itself or other parts on which the tip is placed, as an electrode, to detect a person's contact with the filled tip as a change in ground impedance. A water supply control device for a dental unit, comprising a control circuit that starts water supply control to the bees based on the detection output of the sensor, and controls the water supply to be stopped after a certain period of time from the start of the water supply.
