<p>A water purifier includes a housing containing hot and cold water storage tanks. Hot and cold water spigots are connected to the hot and cold water tanks, respectively, for dispensing hot and cold water. A water retainer tray is disposed beneath the spigots to collect water dripped during dispensing. A residual water discharge pipe discharges the water from the retainer tray. A stored water discharge pipe is connected to the water tanks to enable all water therein to be purged when it is time to clean the tanks. A valve mechanism joins the residual water discharge pipe and the stored water discharge pipe to a common discharge pipe. The valve mechanism is operable such that when the stored water discharge pipe is open to the common discharge pipe, the residual water discharge pipe is closed, to prevent water from backing up to the retainer while the hot and cold water tanks are being drained.</p> |
