[Means for Solving the Problems] However, particularly in the case of a cold water sealed type dispenser using a sterilizing stone, the sealed cold water tank and the sealed hot water tank communicate with each other, and the gas generated from the hot water tank is cooled water. The phenomenon that the water accumulates in the space above the cooling water of the closed type cold water tank and pushes down the water surface of the cooling water, and therefore the gas accumulated on the cooling water is replaced every time the tank containing the natural water is replaced. It was necessary to work to extract it from the top of the sealed hot water tank.

If this degassing work is neglected for a long period of time, there will be a problem that natural water cannot be supplied from the tank containing the natural water to the closed cold water tank. There was a problem that it floated up and hindered the bactericidal effect. The present invention has been devised by focusing on such conventional problems, and prevents invasion of bacteria in the air into the sealed cold water tank and the sealed hot water tank, and effectively contaminates the contents water. In addition, since the gas accumulated on the cooling water is automatically extracted without human intervention, there is no problem that natural water is not supplied from the tank containing natural water to the closed cold water tank. Since the closed cold water tank is always filled with natural water, it is an object of the present invention to provide a drinking water dispenser which can always exert a sufficient sterilizing effect of sterilizing stones.
