Claims

[Scope of utility model registration request]

An outer tank that stands up on the installation surface, an inner tank that stands up within this outer tank at a lower height than the height of the outer tank, and an outer tank that is fitted concentrically to the bottom of the outer periphery of the inner tank in the outer tank. a water tank comprising an annular plate having a plurality of communicating holes; and a water tank configured to supply water from a water supply source into the water tank to a predetermined surface level higher than the height of the inner tank when in an operating state. a water supply system that causes water to flow into the outer tank; an external reflux system that, when activated, leads water in the inner tank outward from its bottom and flows back into the inner tank; A refrigeration cycle includes an annular evaporator fitted and supported directly above the annular plate so as to surround the inner tank, and a refrigeration cycle that cools water in the outer tank with the evaporator; an external faucet that causes water in the reflux system to flow outward; a replenishment system that supplies water from the outer tank into the inner tank from a part of its bottom wall when activated; a water level sensor that detects when the water in the inner tank increases to the predetermined surface level and generates a water level detection signal, a temperature sensor that detects the temperature of the water in the inner tank and generates a temperature detection signal, and disappearance of the water level detection signal. a first control system that controls the water supply system and the replenishment system to be in each operating state and released from each operating state upon generation of each of the water level detection signals; and a second control system that controls the replenishment system to be in operation when the temperature is higher than the ice storage type cold water supply device.
