PURPOSE: A cylinder-type water storage tank is provided to simplify structure, to make the flow of water smooth, and to facilitate the cleaning of the storage tank. CONSTITUTION: Cylinder-type confining walls (6a) (6b) (6c) (6d) with different heights are installed in a main body (4) of the water storage tank. Water overflows the confining walls with low heights (6b) (6d). The confining walls with high heights (6a) (6c) have water discharging holes (12) for transferring water. The floors of compartments are inclined so that the floor of an inner compartment (8a) is higher than the floor of an outer compartment (8e). Water introduced through an inflow hole (16) flows through the compartments (8a) (8b) (8c) (8d) (8e), thereby being mixed with disinfectant owing to the difference between the heights of the floors. The confining walls with low heights have one or more passages for falling flow on the upper side of the wall. The confining walls with low heights are inclined so that an inner confining wall is higher than an outer confining wall in the water storage tank. |
