In describing the operation process of the water purifier according to the present invention configured as described above, it will be divided into the process of discharging drinking water and living water and the process of discharging foreign substances.

First, referring to Figure 2a to look at the discharge process, that is, the water purification process of drinking water and living water as follows.

First, the second solenoid valve 121 on the raw water inlet side port 115a of the three-way valve 115 and the foreign matter discharge pipe 120 side is closed by the control of the controller 600, and the raw water inlet pipe 110 is closed. In the state in which only the first solenoid valve 111 of the side is opened, raw water is introduced through the raw water inflow pipe 110. The raw water introduced through the raw water inlet pipe 110 continues to flow into the lime filtration unit 100.

At this time, since the second solenoid valve 121 of the foreign substance discharge pipe 120 is in a closed state, there is no possibility of leaking through the foreign substance discharge pipe 120.

The raw water passed through the lime filter part 100 is filtered through the limestone material contained therein, and passes through the lime filter part port 115b and the booster pump side port 115c of the three-way valve 115, It is introduced to the booster pump 200 side.

Here, a check valve 201 is provided at the lower end of the booster pump 200 so that the water passing through the lime filtration unit 100 is bypassed toward the oil / water detection unit 210, and the booster pump 200. A detection signal is generated by the oil / water detection unit 210 that detects the inflow of water into the furnace, and when the detection signal is transmitted to the booster pump 200, the booster pump 200 is activated to pressurize the water introduced therein. , Chlorine / mineral filtration unit 300 is introduced.

The chlorine and mineral components remaining in the water by passing through the chlorine / mineral filtration unit 300 are filtered and discharged through the living water discharge unit 310 or through the water purification unit 400 and the heat exchange unit 500. The drinking water is discharged through the discharge portion 520.

Here, the heat exchange part 500 is operated only when hot water is selectively used as an instantaneous heat exchanger of a closed structure. Here, the heating of the heat generating layer 564 of the heat exchange part 500 is configured to be safely operated by the control unit 600 according to the abnormality detection signal of the water level sensor 580 and the temperature sensor 530 to preheat the overheating. Will be prevented.

In addition, even in normal operation, when the internal pressure of the heat exchange part 500 excessively rises, the elevated pressure is transferred to the outside through the foreign matter discharge pipe 120 through the overpressure discharge pipe 595 by the overpressure discharger 590. Is released.

On the other hand, the discharge process of the foreign substances of the chlorine / mineral filtration unit and the lime filtration unit is as follows.

Figure 2b is a schematic diagram showing a foreign matter washing process of the chlorine / mineral filter in the water purifier according to the present invention.

Referring to the drawings, the second solenoid valve 121 and the raw water inlet pipe side port 115a of the three-way valve 115 mounted on the lime filter side foreign matter discharge pipe 120 under the control of the control unit 600 are closed. In the opened state, only the first solenoid valve 111 mounted on the raw water inflow pipe 110 is introduced into the lime filtration unit 100 through the raw water inflow pipe 110.

The raw water passing through the lime filter part 100 is introduced into the booster pump 200 through the lime filter part port 115b and the booster pump side port 115c of the three-way valve 115. The raw water pressurized by the booster pump 200 is introduced into the chlorine / mineral filtration unit 300 through the oil / water detection unit 210, and the foreign matter inside the chlorine / mineral filtration unit 300 is chlorine in accordance with the flow of water. It is discharged through the foreign substance discharge pipe 320 / mineral filter side. Here, the discharge of the foreign matter due to the pressurized by the booster pump 200 is made much easier, and the third solenoid valve 311 mounted on the living water discharge portion 310 connected to the lower portion of the chlorine / mineral filtration unit 300. ) Is closed, and since the fourth solenoid valve 321 mounted on the chlorine / mineral filtration unit foreign substance discharge pipe 320 is open, foreign substances are not discharged through the living water discharge unit 310.

Figure 2c is a schematic diagram showing a foreign matter cleaning process of the lime filter of the water purifier according to the present invention.

Referring to the drawings, the first solenoid valve 111 on the raw water inlet pipe 110 side and the booster pump side port 115c of the three-way valve 115 are closed by the control of the controller 600, and the foreign substance discharge pipe In the state in which only the second solenoid valve 121 at the side of 120 is opened, raw water is introduced through the raw water inflow pipe 110. The raw water introduced through the raw water inflow pipe 110 is introduced into the lime filtration unit 100 through the raw water inflow pipe side port 115a and the lime filter side port 115b of the three-way valve 115. .

At this time, since the booster pump side port 115c of the three-way valve 115 is closed, since the raw water does not flow into the booster pump 200, the water flow detector 210 does not generate a detection signal, and the booster pump 200 ) Is only activated when receiving the detection signal by the water flow detecting unit 210, the booster pump 200 is also maintained in a stopped state.

Separator 102 is separated from the guide 101 by the water flowing into the guide 101 of the lime filtration unit 100 while floating, the cotton yarn filter ( The folded portion of 103 is unfolded.

At this time, as the cotton yarn filter 103 is unfolded, foreign substances such as limestone accumulated in the cotton yarn filter 103 are discharged through the foreign matter discharge pipe 120 at the lime filtration part according to the flow of water.

Here, since the first solenoid valve 111 of the raw water inlet pipe 110 is closed, there is no possibility that foreign substances are discharged through the raw water inlet pipe 110.
