The operating state of the vehicle-mounted cold / hot water heater system will now be described.

First, when the user selects the cold water switch configured in the switch panel 142, the motor pump 112 generates pressure in the normal direction to pump the water stored in the water tank 5. [

The pumped water is then prevented from flowing back through solenoid valve 114 via motor pump 112 and the cold water purified by filter 116 is located in cold water valve 112.

At this time, since the cold water valve 112 is in the open state, it is drained to the outside through the hose to be taken out

In this case, the circulation valve 137 and the hot water valve 138 of the hot water line 130 are kept in the closed state, so that water in the water tank 5 sucked by the positive pressure of the motor pump 112 The cold water line 120 can not be introduced into the hot water line 130 due to the difference.

When the user selects the hot water switch configured in the switch panel 142, the hot water valve 138 is opened, whereby the water stored in the hot water tank 132 is drained to the hose through the hot water valve 138 to be withdrawn

In this case, the circulation valve 137 of the hot water line 130 and the cold water valve 122 of the cold water line 120 are maintained in the closed state, so that the water tank 5 sucked by the forward pressure of the motor pump 112 Is not allowed to enter the cold water line 120 due to a difference in pressure, but is drained to the hot water line 120 only.

As shown in FIG. 4, a method of completely draining water located in the inside of the cold / hot water heater is as follows.

In the drain switch selection step s20, the drain switch configured in the switch panel 142 of the control unit 140 is selected.

When the drain switch is selected, the control unit 140 sends a control signal to open the hot water valve 138 and the solenoid valve to open the hot water valve and the solenoid valve 114

The actuation step s20 of the motor pump is started when the hot water valve 138 and the solenoid valve 114 are opened through the hot water valve and the solenoid valve opening step s20 so that the motor pump 112 operates in the control part 140 And a pumping pressure is generated in the motor pump 112

In the drainage step s20, when reverse pressure is generated in the motor pump 112 through the motor pump operation s24, the water remaining in the hot water valve 138 is discharged by the pressure of the motor pump 112 And is sucked and recovered to the water bottle 5 along the pipe.

In this case, since the pipe connected to the hot water bottle 132 of the hot water line 130 is located on the bottom surface of the hot water bottle 132, the reverse pressure of the motor pump 112 causes the pipe The stored remaining water is completely recovered through the piping.

Thus, even if the water remaining in the water heater 10 is completely recovered and the external temperature falls below zero as in the winter, the risk of the frozen water is eliminated.
