Abstract: Exemplary embodiments include tanks for cooling liquid where at least two thermoelectric chips come into contact with and cool a plurality of conductive fins that each extend into the interior of the tank where they come into contact with and thereby chill fluid as it is housed in and flows between two connected chambers within the tank.

Abstract: A spout that dispenses water from a water dispenser has a disinfection portion that provides two passes of the water therethrough. The disinfection portion has two flow tubes, the second arranged inside the first, so that an annular cross-section flow path is defined by an inside wall of first tube and an outside wall of the second tube. A second flow path having a circular cross-section is defined by an inside wall of the second tube. The water flow is transferred between the flow at a second end of the disinfection portion by a second end portion. At a first end portion, located at a first end of the disinfection portion, a first end portion body provides connections to the disinfection section for both an inlet and an outlet. The order of flow through the disinfection portion flow paths may depend upon the orientation of the spout.

Abstract: A system for and method of sanitizing water and waterway surfaces using ozone gas is disclosed wherein water is circulated from a water reservoir in a water ozonation loop means. Ozone is generated by an ozone generator and dispensed into the circulating water by an ozone feed means. In some embodiments the ozone is generated from gas in the water reservoir and dispensed into the water ozonation loop means at a venturi tube. A controller is provided for activating an ozonation cycle. In some embodiments, the ozonation cycle includes the actuation of a circulating water pump for a cycle interval, and the actuation of an ozone generator during an ozone generation interval, which is less than the cycle interval.

Abstract: A device for preventing the overflow of a fluid reservoir, having a first tubular body with a hole through the interior and exterior surfaces at one end, a second tubular body disposed within the first body such that a portion of the interior surface of the first body and the exterior surface of the second body define an air channel, and a floatation device. The position of the tubular bodies relative to one another determine whether air from a fluid reservoir may exit the reservoir via the hole in the end of the first body. The flotation device is connected to an end of the second body and floats in the fluid reservoir wherein movement of the second body relative to the first body is caused by a change in the water level, such that the air channel is opened or closed by the position of the floatation device.

Abstract: Described is a filter cartridge having a cup shape that can be filled with a filtering material, and placed in a filtering device such as a water pitcher. The filter cartridge has a base, a side wall, and a flange defining the cup shape of the filter cartridge. A removable mesh insert may be affixed atop the flange, allowing replacement of the filtering material.
