When the hot water valve 112 of the on-off valve 100 is closed and the hot water opening / closing portion 111 blocks the room temperature bypass passage 110 in the main body, the water pressure of the tap water (raw water) is blocked by the hot water opening / closing portion 111. Therefore, the water pressure of the tap water (raw water) does not act on the hot water tank (1) of the water purifier. And the inside of the hot water tank (1) is because the hot water pipe (H) and the hot water hose 203, the hot water passage of the on-off valve 100, and the discharge pipe 140 there is no blocking device inside the hot water tank (1) The pressure at is about atmospheric pressure.

Therefore, even when the hot water tank 1 is overheated due to a failure of the temperature control device in the heating process by the heater, the hot water tank 1 does not generate an overpressure enough to explode. Even in this case, since the steam is discharged to the drain through the discharge hose 301 by the opening of the overpressure valve 300, a large amount of hot steam is not discharged through the discharge pipe 140. Therefore, when the hot water valve 112 is opened, steam and hot water are discharged at one time, and burns do not occur.

And as described above, even when a certain overpressure occurs in the hot water tank 1, the steam is discharged through the discharge hose 301 by the overpressure valve 300, so that other pipe joints do not leak.

In the hot water tank (1) it may be to block the operation of the heating device if the overheating state for a certain time or more.

Opening the hot water bypass passage 110 of the on-off valve 100 by opening the hot water valve 112 in a state in which the heating action of the hot water tank 1 operates normally, the purified normal temperature water branch pipe of the normal temperature water pipe (N) ( From S), it flows into the normal temperature water bypass passage 110 of the on-off valve 100 via the normal temperature water inlet hose 201, and then flows out to the normal temperature water outlet hose 202 to enter the hot water tank 1. In the hot water tank (1) is heated by the heating apparatus and then enters the hot water passage of the on-off valve 100 through the hot water hose 203 is discharged hot water through the discharge pipe 140.

If the hot water bypass 112 is closed by closing the hot water valve 112 in a state where hot water is discharged, the hot water is no longer applied to the hot water of the hot water container 1, so that the hot water is not discharged from the discharge pipe 140.

The water purifier hot water tank overpressure prevention device of the present invention configured as described above is a hot water tank in all water purifiers equipped with a hot water tank for supplying hot water, so that the water pressure does not act on the hot water tank and is in communication with the atmosphere through the discharge pipe.
