<p>PROBLEM TO BE SOLVED: To exactly execute water discharging operation by providing a control means for judging the finishing time of water discharge by inputting the amplification value of a signal sensed by a residual water sensing means. SOLUTION: A key signal input means 100 inputs a key signal for discharging a purified water in a purified water tank. A water discharge driving means 106 discharges the purified water in the purified water tank according to the key signal inputted by the key input means 100. The residual water sensing means 102 senses the quantity of the purified water remaining in the purified water tank at the time of water discharging operation by the water discharge driving means 106. The control means 104 judges the finishing time of water discharge by inputting the amplification value of the signal sensed by the residual water sensing means 102. A reporting means 108 reports the finishing time of the water discharge by the control of the control means 104. As a result, since the finishing time of water discharge is accurately grasped, the water discharging operation is accurately performed.</p> |
