Abstract
Abstract The present invention is directed to a device for producing carbonated water. The device includes a hermetic container, a first pipe member continually conducting a carbonic acid gas into an inner hollow space of the hermetic container, a second pipe member intermittently conducting pressurized water into the inner hollow space of the hermetic container in response to demand, and a third pipe member intermittently conducting carbonated water temporarily staying in the container to a location outside of the container in response to demand. A nozzle is connected to one end of the second pipe member and is disposed within the container at a top end thereof. The nozzle has a plurality of holes which allow the pressurized water to be downwardly injected into the inner hollow space of the container. A plate member may be disposed within the inner hollow space of the container. The plate member includes a first hole which is located at a position corresponding to a downward path of the injected water, and at least one second hole which is located at a position offset from an upward path of the injected water.
