1. A direct water purifier, comprising:
a filter for filtering water;
a pump for supplying water having a predetermined hydraulic pressure or higher to the filter;
a heater configured to heat purified water inflowing by hydraulic pressure of the pump to a predetermined temperature and discharging the heated water;
a hot water valve adjusting a flow rate of the purified water supplied to the heater such that the purified water supplied to the heater is heated to be hot water having a predetermined temperature; and
a flushing valve disposed in a flushing flow path through which concentrated water is discharged from the filter,
wherein the flushing valve opens the flushing flow path during the purified water flowing at a flow rate controlled by the hot water valve is heated by the heater,
wherein the direct water purifier further comprises an eighth valve formed as resistors on an eighth flow path, and a ninth valve formed as resistors on a rear end of a seventh valve on a seventh flow path, the seventh valve being directly connected to the filter to prevent excessive pressure rise at the pump.
