WATER TREATMENT APPARATUS

PROBLEM TO BE SOLVED: To provide a water treatment apparatus which calculates a used objective water volume utilizing the measured results of a water flow volume in a flow channel through which water other than the objective water flows and by considering some other factors and displays the result, thus allowing a user to adequately figure out the water volume actually used, maintaining a simple flow measuring mechanism as it is. SOLUTION: Using a measuring means for measuring a water flow volume including the objective water, a calculation means of this apparatus calculates an effectual water volume corresponding to the objective water volume actually used from the information on the obtained flow volume and a display means displays the obtained effectual water volume. Moreover, this apparatus gives an indication of the used objective water volume to the user when the user is actually using the objective water by starting the calculation and display process on the point of time when the supply of the objective water is started with the water actually flowing. Therefore, in this manner the user can easily figure out the used objective water volume by the display of the effectual water volume obtained by the adequate estimation of the used objective water volume, thus properly controlling the use of the water by recognizing the used water volume such as for drinking for certain.
