And a piping system of a water softener so that the piping can be simplified by the drainage to one drain pipe.

Water softener is a device that converts soft water (smooth water) such as tap water into soft water (single water) .It absorbs and removes impurities such as green water and colloid in raw water, making it especially soft and clean water for skin beauty. do.

For example, strong acidic cation exchange resins are used to exchange hard water-inducing substances (calcium, magnesium, etc.) in water to convert hard water into soft water. More specifically, they are bonded to the synthetic resins of ion exchange resins by ionic bonds. Allow ions to be exchanged with ions of the same sign in the original water.

The cold water softener is connected to the pipe so that the cold water is supplied to the water softener, and the hot water softener is connected to the pipe so that the hot water is supplied.

In addition, the water softener deteriorates the softening performance after a certain period of time, so that the ion exchange resin in the softener performing the softening action must be regenerated.

As shown, the piping system of the conventional water softener is provided with a hot water tank and a cold water tank formed with an inlet and an outlet, and the hot water tank and the cold water tank are connected to each other by pipes, and valves of various functions are installed in a symmetrical structure. have.

The conventional water softener piping system is a water softener having a hot water tank 10 and a cold water tank 20 filled with ion exchange resin, and each of the inlets 11 and 21 of the hot water tank 10 and the cold water tank 20. And three-way valves 13 and 23 are installed on the pipe connected between the outlets 12 and 22, and the hot water inlet pipe 14 and the cold water tank 20 to the three-way valve 13 of the hot water tank 10. It is made of a structure in which the cold water inlet pipe 24 is connected to the three-way valve (23).

And the piping system of the conventional water softener is provided with drain pipes 15 and 25 communicating with the inlet port 11 of the hot water tank 10 and the inlet port 21 of the cold water tank 20, respectively, the drain pipe 15 (25) includes a structure in which drain valves 16 and 26 are provided to open and close these drain pipes 15 and 25, respectively.

And the piping system of the conventional water softener is the on-off valve (17, 27) is installed on the pipe connecting the outlet 12 of the hot water tank and the outlet 22 of the cold water tank, one between the open and close valves (17, 27) The brine supply pipe 31 is connected to the brine injection valve 32 and the brine injection pump (not shown) is installed, the inlet (11, 21) and outlet of each of the hot water tank (10) and cold water tank (20) The hot water outlet pipe 18 and the cold water outlet pipe 28 are connected to the outlet ports 12 and 22 of the pipe connecting the pipes 12 and 22.

In addition, regulators 19 and 29 are installed in the hot water inlet pipe 14 and the cold water inlet pipe 24, respectively, to adjust the inlet pressures of the hot and cold water.

Here, the three-way valve (13, 23) and the on-off valve (17, 27) is an electronically controlled electronic valve, the drain valve (16, 26) and salt water injection valve 32 is a manual valve.

Thus, although not shown in the conventional water softener, a control panel for automatically controlling and displaying various operations is provided at the front.

The control panel includes a time display section, a start button for starting softening, a regeneration button for regenerating the ion exchange resin, a time setting button for setting the time, a time setting button for setting the regeneration time of the ion exchange resin, and a time setting. Or an up button for increasing the number of the time display section at the time of setting the regeneration time of the ion exchange resin, a down button for down the number of the time display section at the time of setting the time or setting the regeneration time of the ion exchange resin, ion exchange It consists of a regeneration indicator which is lit during the regeneration of the resin, a brine injection indicator which is activated when the brine is supplied during regeneration of the ion exchange resin, and a start indicator which is lit when the start button is pressed.

The water softening process and the regeneration process of the ion exchange resin using the piping system of the conventional water softener as described above are as follows.

Since the piping system formed in the hot water tank and the cold water tank in the present invention is performed by the same operation, respectively, by the symmetrical configuration, the softening and regeneration process of soft water is replaced by the description of the softening and regeneration process of cold water.

First, the training process is explained.

When the user presses the start button on the control panel, the start indicator is turned on, and the three-way valve 13 is operated to open the upper direction of the hot water tank.

Then, the hot water is introduced into the hot water inlet pipe 14 and introduced into the hot water tank 10 through the three-way valve 13 and the inlet 11, and the introduced hot water passes through the ion exchange resin filled in the tank. Water softening takes place.

In other words, the ion exchange resin of the strong acid cation filled in the tank exchanges the hardness-inducing substances (calcium, magnesium, etc.) of the influent water with sodium, converts the hard water into soft water, and removes impurities such as green water and colloid to make the water soft and clean.

The water softened in this way is discharged to the outside through the hot water outlet pipe 18 to be in a usable state.

At this time, since the regulator 19 is installed on the hot water inlet pipe 14, it is possible to control the water pressure of the influent according to the capacity of the tank.

On the other hand, the water softener deteriorates the performance of the charged ion exchange resin when used for a certain period.

The regeneration of the ion exchange resin was performed for two primary back washes for about three minutes, two primary rinses for one minute, two brine injections and circulation for seven minutes, and for two minutes. Two second back washes, two second rinse cycles for two minutes, each of which is described in detail.

Primary back washing

When the user presses the play button on the control panel, the indicator light during play is turned on, the three-way valve 13 is operated to open the downward direction, and the drain valve 16 is manually operated to be opened.

Then, the hot water is introduced into the hot water inlet pipe 14 and introduced into the hot water tank 10 through the downward direction and the outlet port 12 of the three-way valve 13, the introduced hot water passes through the ion exchange resin filled in the tank It is discharged through the inlet 11 and discharged to the outside through the drain pipe 15 and the drain valve 16 piped thereto. At this time, the hot water outlet pipe 18 should be closed.

In other words, the flow of raw water is reversed in the opposite direction to the flow of water when using soft water to release the compressed ion exchange resin by water pressure to reduce the filling state of resin particles, and to wash suspended matter and suspended matter deposited on the resin layer. And backwashing such as removing gas in the resin.

This primary back washing operation is preferably performed twice for about 3 minutes.

1st rinse

After the action of the back wash is the first rinse action is performed automatically, the rinsing action is described as follows.

If the washing button on the control panel is pressed while the drain valve 16 is closed, the three-way valve 13 is operated to open the upper direction of the hot water tank. Then, the hot water flows into the hot water inlet pipe 14 and the three-way valve. 13 and the inlet 11 is introduced into the hot water tank 10, the introduced hot water washes the suspension in the course of passing the ion exchange resin filled in the tank and the resin layer is settled to the next step of salt water injection Upon contact is made smoothly discharged through the hot water outlet pipe (18).

The rinsing action as described above is preferably performed twice a minute.

Salt water injection and circulation

After the first back washing and the first rinsing action, the brine injection and circulation is started.

Brine injection and circulation is a process of restoring the performance of ion exchange resin by desorbing and replacing the impurity ion component adsorbed by ion exchange resin with brine (regeneration agent) when using soft water. It is a process.

That is, the hot water outlet pipe 18 is closed, and the drain valve 16, the on-off valve 17, and the salt water injection valve 32 are opened to soak the salt water supply pipe 31 in the salt water tank to operate a pump (not shown). In other words, the brine is introduced into the tank through the outlet 12 of the hot water tank 10 and acts with the filled ion exchange resin and is discharged to the inlet 11 of the tank and through the drain pipe 15 and the drain valve 16. It is discharged to the outside.

This brine injection and circulation is preferably carried out twice for about 7 minutes.

2nd clear back washing

After the brine injection and circulation process is completed, the second backwashing process is performed twice for about two minutes, and the second backwashing operation is performed in the same manner as the primary backwashing operation described above.

That is, while the raw water flows in the hot water tank 10 in the reverse direction, it performs a washing action on the ion exchange resin.

2nd rinse

After the second back wash action, the second rinse action is performed twice for about 2 minutes to completely wash out the brine and hardness components remaining in the resin layer. It is done in the same way. In other words, hot water and cold water pass through the ion exchange resin in the forward direction to perform a rinse action.

The softening process of the hot or cold water as described above and the regeneration process of the ion exchange resin is electronically controlled by the microcomputer, the program for controlling the on-off valve is stored in the microcomputer.
