Thereafter, the water is discharged through the drain pipe 51 through the water inlet 31 and the fourth cold water open / close valve 41.

Rinse

When the back washing action is completed, the rinsing action is automatically performed. For this purpose, the first hot water open / close valve 14, the fifth hot water open / close valve 22, the first cold water open / close valve 34, and the fifth cold water open / close valve ( 42) Open.

At this time, the hot water flows into the upper portion of the hot water tank 10 through the hot water supply pipe 18, the first hot water open / close valve 14, and the inlet 11, and rinses while passing the ion exchange resin in the hot water tank 10 in the forward direction. After the operation, the water is discharged through the drain pipe 51 via the water outlet 12 and the fifth hot water opening / closing valve 22.

Cold water flows into the upper portion of the cold water tank 30 through the cold water supply pipe 38, the first cold water open / close valve 34, and the inlet 31, and rinses the ion exchange resin in the cold water tank 30 in a forward direction. After that, the water is discharged through the drain pipe 51 through the water outlet 32 and the fifth cold water open / close valve 42.

-Brine injection and circulation

After the backwashing and rinsing, the alarm of the controller sounds. At this time, the user connects the pump (not shown) to the brine injection pipe 50 and operates the brine prepared separately to supply the system, and then presses the regeneration button to open and close the fourth hot water opening / closing valve 21 and the fourth cold water opening and closing. Open the valve 41.

Then the brine is introduced into the lower portion of the hot water tank 10 through the brine injection pipe 50, the outlet 12 of the hot water tank 10, and then exits the hot water tank 10 through the upper inlet 11 Drain pipe 51 is discharged, and the brine is also introduced into the lower portion of the cold water tank 30 through the water inlet 32 of the salt water injection pipe 50, the cold water tank 30, the upper inlet 31 After exiting the cold water tank 30 through it is discharged through the drain pipe (51).

Clear back washing

After the brine injection and circulation process is completed, a clear back washing process is performed for 2 minutes, and the clear back washing action is performed in the same manner as the above back washing action. In other words, the hot water or cold water flows in the reverse direction through the hot water tank 10 and the cold water tank 30, respectively, and performs washing with respect to the ion exchange resin.

Rinse

After the clear back wash action is finished, a rinse action is then performed for 2 minutes, in the same manner as the rinse action described above. In other words, hot water and cold water pass through the ion exchange resin in the forward direction to perform a rinse action.

When the regeneration action is finished and the water softener is normally used, the soft water is discharged by the following action.

When the user presses the start button of the control unit to receive soft water, the first hot water open / close valve 14, the third hot water open / close valve 20, the first cold water open / close valve 34, and the third hot water open / close valve 40 are opened. do.

Then the hot water is introduced through the hot water supply pipe 18 is introduced into the upper portion of the hot water tank 10 through the first hot water opening and closing valve 14 and the inlet (11). The hot water is softened by the ion exchange resin in the hot water tank 10 and then discharged through the water outlet 12 and discharged through the hot water discharge pipe 19 through the third hot water opening / closing valve 20.

The cold water is introduced through the cold water supply pipe 38, and is introduced into the upper portion of the cold water tank 30 through the first cold water open / close valve 34 and the inlet 31. The cold water is softened by the ion exchange resin in the cold water tank 30 and then discharged through the water outlet 32 and discharged through the cold water discharge pipe 39 through the third cold water open / close valve 40.

The hot and cold water and cold rolled water supplied by the above action are properly mixed and discharged by a mixing valve (not shown) directly operated by a user.

In the above-described conventional water softener, in order to inject and circulate salt water in the hot water tank 10 and the cold water tank 30 in the regeneration process, the salt water injection pipe 50 is connected to the hot water tank 10 and the cold water tank 30, respectively. do. The brine injection pipe 50 is used in connection with the pump for the brine injection, circulation during the regeneration action, but when using a normal water softener is unnecessary because the brine injection, circulation is not necessary.

However, since the brine injection pipe 50 directly communicates with the outlet 12 of the hot water tank 10 and the outlet 32 of the cold water tank 30, the hot water tank 10 and the cold water tank 30 when using a normal water softener. The hot water of the hot water tank 10 flows into the cold water tank 30 or cold water of the cold water tank 30 flows into the hot water tank 10 by the hydraulic pressure difference of the.

Therefore, when the user wants to receive only hot soft water with high temperature, the cold soft water is mixed with the hot soft water or when the user wants to be supplied with cold water with low temperature, the hot soft water is mixed with the cold soft water and discharged. Since the mixing ratio of soft water and cold soft water cannot be easily adjusted, soft water of a desired temperature cannot be easily supplied, and thus there is a problem in that the soft water of the user is inconvenient.

In addition, when the abnormal flow of the hot water or cold water occurs as described above, there is a problem in that the soft water efficiency decreases due to the inflow of cold or hot water into the hot water tank 10 or the cold water tank 30.

The present invention has been made to solve such a problem in the prior art, and the salt water injection and circulation during the regeneration process of the ion exchange resin can be injected and circulated in the brine, and the hot water of the hot water tank in the normal water softener using cold water Prevent cold water from flowing into the tank or flowing from the cold water tank to the hot water tank, so as not to affect the temperature of the hot and cold water, so that the user can easily obtain the soft water at the desired temperature and use the water softener conveniently. It is also an object of the present invention to provide an ion exchange resin regeneration system for a water softener to prevent a decrease in water softening efficiency.

The present invention for achieving the above object is provided with a hot water tank and a cold water tank, the water softener is connected to each of the brine injection pipe to the outlet of the hot water tank and cold water tank to inject and circulate the salt water during the regeneration of the ion exchange resin In the ion exchange resin recycling system of the present invention, check valves are provided in the brine inlet pipes on the outlet side of the hot water tank and the cold water tank, respectively so that water flows only toward the outlet port and water does not flow in the opposite direction.
