DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water softener using an ion-exchange resin. Related to inexpensive water softeners.

[0002]

2. Description of the Related Art Conventional water softeners made of ion-exchange resin have a pre-programmed automatic control valve to collect soft water.
There is a water softener that automatically switches the process of backwashing and regeneration.
This type of water softener is expensive and unsuitable for small households. Further, when a power failure or the like occurs, the program is disrupted and malfunctions occur. As a result, the operation of the water softener must be stopped, which is not suitable for housewives at home. Conversely, a water softener without a switching valve is also commercially available, but it is compact and inexpensive.However, when regenerating, remove the upper cap and put a certain amount of salt into the ion exchange resin container to regenerate. I was In this case, the operation was difficult, and the operation was inconvenient such as overflowing the water.

[0003]

Recently, not only small-scale facilities such as restaurants, but also small-scale homes and the like have a demand for water softeners, and the following needs have arisen. That is, the water softener with the saline solution container 22 is small and inexpensive and can be easily and safely regenerated by a housewife at home. The amount of salt required for one regeneration operation (about 120 g per liter of ion exchange resin) is measured in advance and prepared as a salt solution 23 in a salt solution container 22, and when the ion exchange resin 20 deteriorates, Saline solution container 2
2 is connected to the salt water cock 8 through the saline water conduit 21, and the tap water is caused to flow, so that the salt water 23 is sent into the ion exchange resin container 4 by the flow of the tap water, and the salt water is exhausted. The regeneration of the ion exchange resin 4 is completed.

[0004]

A switching valve body 7 having an ion exchange resin container 4 containing an ion exchange resin 20, a tap water inlet, a soft water outlet, and a salt water cock 8.
And an ion exchange resin water softener provided with a vertical three-stage switching valve comprising a vertical conical switching valve 12 having an ejector 16 therein, a filter tube 17 and a conducting pipe 18 having a filter 19 at the tip. Then, when the ion exchange resin 20 is deteriorated, the saline solution container 22 is connected to the saline solution cock 8 by a saline solution conduit 21 and the tap water is allowed to flow therethrough, so that the saline solution 23 in the saline solution container 22 is removed. To the ion exchange resin container 4 by the flow of tap water.
And the regeneration of the ion-exchange resin 20 is completed when the saline solution 23 is used up.

[0005]

In the present invention, when collecting soft water, the switching lever 10 is set to the soft water position and the water tap 1 is opened.
The vertical three-stage switching valve 12 enters the ion-exchange resin container 4 and is softened by the ion-exchange resin 20. More soft water is collected. When the ion-exchange resin 20 is deteriorated, it is necessary to regenerate the ion-exchange resin 20 with a saline solution.
It is necessary to release 0 and wash away small foreign matter. This is called backwashing. Next, the backwashing operation will be described. When the switching lever 10 is set to the backwash position and the water tap 1 is opened, the water passes through the vertical three-stage switching valve 12,
When the ion-exchange resin 20 enters the ion-exchange resin container 4 through the filter 19 and flows upward from below through the filter 19, the ion-exchange resin 20 is dislodged while being stirred upward, and small foreign substances are washed away. After passing through the vertical three-stage switching valve 12, it is discharged from the soft water conduit 3 and washed. Next, the reproduction operation will be described. When the switching lever 12 is set to the regeneration position, the saline solution container 22 and the saline solution cock 8 are connected by the saline solution conduit 21, the saline solution cock 8 is opened, and the tap water tap 1 is opened. Is passed through the ion-exchange resin 4 from the filter cylinder 17 through the switching valve 12, and is discharged from the lower filter 19 and the conducting pipe 18 through the soft water conduit 3 from the vertical three-stage switching valve 12. If the tap water is kept flowing in this state, the tap water is fed into the ion exchange resin container 4 while sucking the saline solution 23 by the action of the ejector 16, and the soft water conduit 3 is activated while the ion exchange resin 20 is activated. Is more exhausted. When the saline solution is introduced into the upper portion of the ion exchange resin 20 and flows downward, the Ca ⁺⁺ Mg adsorbed
^{The ++} hard water component is gradually replaced by Na ions in the saline, and is activated and regenerated.
