Abstract

PROBLEM TO BE SOLVED: To obtain the salt regeneration device which is an attachment type device and enables simplification of the regeneration operation of an ion exchange resin water-softener by placing a base main body provided with a two-way switching valve and a salt vessel provided in its screwed base with a double pipe, in the salt regeneration device that is positioned between a water tap and an ion exchange resin water-softener and connected to both of them. SOLUTION: This salt regeneration device consists of a base main body provided with a two-way switching valve 40 and a salt vessel 47 provided with a double pipe consisting of an outer pipe 44 and an inner pipe 45. In the salt regeneration device, when a salt cartridge (consisting of the salt vessel 47) containing salt 48 (sodium chloride) is screwed into the base main body, the two-way switching valve 40 is rotated and elevated to switch the water flow passage from a straight flow passage to a bypass flow passage and tap water is allowed to flow into the base main body through a conduit 2, and successively passed through an inflow base 34 of a two-way switching valve main body 33, an inflow port 33-1, the outer pipe 44 and inner pipe 45, in that order. Thereafter, the tap water is jetted out from an inflow/outflow port 46-1 of a front end cap 46 of the double pipe into the salt vessel 47 to dissolve the salt 48 in the water and to form salt water, and then, the salt water is allowed to flow again upward through the inflow/outflow port 46-1 and the inside of the inner pipe 45 and then, successively passed through each of flow passage ports 40-4, 40-5 and 40-1 of the two-way switching valve 40 in that order and reaches another conduit 2 through an inflow base 35, to introduce the salt water into an ion exchange resin water-softener. By passing this salt water through ion exchange resins in the water-softener, the ion exchange resins can be regenerated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a salt regenerator used in connection between a water tap and a water softener using an ion exchange resin. The present invention relates to a simple salt regenerator.

[0002]

2. Description of the Related Art In a conventional water softener using an ion-exchange resin, the deteriorated ion-exchange resin is obtained by removing the ion-exchange resin contained in a cloth bag from a water softener and replacing it with a regenerated ion-exchange resin contained in a cloth bag in advance. Alternatively, the upper cap was removed, a certain amount of salt was placed in a water softener container, and reactivated, that is, regenerated while running tap water.

[0003]

In a small water softener, the capacity of the ion exchange resin is small, the frequency of regenerating the resin increases, and the regenerating operation is troublesome, and the water overflows every time. It was inconvenient. In recent years, despite the widespread use of small water softeners, such regeneration operations have been inconvenient and often have not been used easily. An object of the present invention is to provide an attachment-type salt regenerator that is simple and convenient to regenerate by directly connecting the present salt regenerator to such a water softener. Even a housewife at home can easily and safely convert it to a water softener that can be regenerated. This aims to increase the utility of the water softener and to stimulate demand for a new small water softener.

[0004]

The salt regenerator of the present invention comprises:
It is used by being directly connected between the water tap 1 and a water softener containing the ion exchange resin 10. This salt regenerator switches a channel flowing in a direct direction and a bypass channel, a base body having a two-way switching valve, and a screw container provided with a double pipe, a salt container in which salt is placed. Screwed in,
It is a so-called salt regenerator of an ion exchange resin water softener composed of a so-called salt cartridge.

[0005]

The salt regenerator of the present invention is directly connected between the water tap 1 and the water softener containing the ion exchange resin 10. When a salt container containing salt is screwed into a screw base portion provided with a double pipe in a base body portion having a two-way switching valve directly connected, when screwing a so-called salt cartridge, two-way switching is performed at the same time. While pushing up the valve, it is switched to the bypass flow path, and the tap water is jetted out of the double pipe into the salt container and sent to the water softener as salt solution while dissolving the salt to regenerate the ion exchange resin. When the salt in the clear salt container is completely dissolved, stop the tap and remove the salt cartridge by rotating it in the reverse direction. In synchronism with the reverse rotation, the two-way switching valve is rotated and depressed to switch to a flow path flowing in a direct direction. When the tap is opened, the tap water is guided directly to the water softener,
Water is softened and soft water is collected. Next, when regenerating, salt (about 1 liter per ion exchange resin
Prepare a salt container containing 20 grams).

DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of the present invention will be described with reference to the drawings while explaining a conventional water softener (FIG. 1). Reference numeral 1 denotes a water tap, which is led to a water softener vessel 4 by a conduit 2 and adsorbs Ca ⁺⁺ and Mg ⁺⁺ as hard water components by an ion exchange resin 10 therein, and soft water is collected from the discharge pipe 3 as soft water. 6 is a cap, 7 is a switching valve, and 9 is a handle. (Fig. 2)
Is a cross-sectional view of a conventional general water softener. here,
Since this is not the gist of the present invention, a brief description will be given. Reference numeral 4 denotes a water softener container in which an ion exchange resin 10 is placed.
5 is a leg and 6 is a cap. 7 is a switching valve, 9
Is a switching handle. When the tap 1 is opened, tap water enters the switching valve 7 through the conduit port 2-1 and flows below the upper layer of the ion exchange resin 10 through the filter 11. At this time, the water is softened and the conduit 12 is passed through the lower filter 13.
And soft water is collected from the discharge port 3-1 through the switching valve 7. When the handle 9 is turned 90 degrees to the backwash position and the tap 1 is opened, tap water flows from the conduit port 2-1 through the switching valve 7 and upwards from the conduit 12 and the lower filter 13. The gas enters the switching valve 7 from the filter 11 and is discharged from the discharge port 3-1. At this time, the ion exchange resin 10 is washed (called backwashing) upward by a water flow so as to be loosened. This back washing is performed as a pretreatment for regeneration with a saline solution. Next, the usage of the salt regenerator of the present invention attached to a conventional water softener is shown in FIGS. 3 and 4 as sketches. (Fig. 3)
Is a sketch when the salt regenerator A part (upright type) of the present invention is fixed near the water softener with the mounting bracket 31, and the water softener and the water tap 1 are directly connected with the conduit 2, respectively. Show. (FIG. 4) shows a sketch when the salt regenerating unit B (inverted type) of the present invention is installed on the base plate 32 near the water tap 1 and is directly connected to the water tap 1 and the water softener by the conduit 2. .

FIG. 5 is a sectional view of a salt regenerator A (upright type) according to the present invention. First, the structure will be described.
The two-way switching valve body 33 is screwed and fixed to the base plate 31. An inlet port 34 and an outlet port 35 are screwed into the two-way switching valve body 33, and the conduits 2 are connected to each other by conduit fixing nuts 36. Inside, a two-way switching valve 40 has an O-ring 41 and a screw portion 4.
It is rotatably inserted at 0-2, and a holding screw 37 is screwed via an O-ring 38. A salt container cap 42 is screwed from below the two-way switching valve body 33 via an O-ring 43. An inner pipe 45 and an outer pipe 44 are fixed to the center of the salt container cap 42, respectively. A distal end cap 46 is screwed into the distal end of the outer pipe 44. Further, a salt container 47 containing salt 48 is screwed into the salt container cap 42 via an O-ring 52. In order to make it easy to understand, the description will be made with reference to a partial view. In FIG. 6, a salt container 47 containing salt 48 is screwed into the salt container cap 42 via an O-ring 52. This is a so-called salt cartridge, and its sectional view is shown. (FIG. 7) shows a sketch of the salt container cap 42. 42-2 is an inflow port to the flow path between the outer pipe 44 and the inner pipe 45. Tip 42
-1 is a hexagonal shape, when the salt cartridge is screwed in the forward rotation, and when the reverse rotation screw is removed,
The hexagonal hole portion 40-3 of the two-way switching valve 40 is fitted,
By rotating in synchronization, the two-way switching valve 4
0 is moved up and down, and the flow path is switched. FIG. 8 shows a cross-sectional view of the two-way switching valve 40. (FIG. 9) shows an upper plan view of (FIG. 8). (FIG. 10) shows a lower plan view of (FIG. 8). 40-2 is a screw part,
The channel is switched by moving up and down. 40-1 is four circulation holes. Reference numeral 40-3 denotes a hexagonal hole, which is a hexagonal portion 42 at the tip of the salt container cap 42.
-1 and rotation is transmitted. Next, the operation of the salt regenerator configured as described above will be described with reference to FIG. As shown in FIG. 5, when the above-described salt cartridge containing the salt 48 is completely screwed in, the two-way switching valve 40 is also rotated upward, thereby moving upward and forming a bypass flow path. When the tap water 1 is opened, the tap water flows from the conduit 2 in the direction of the arrow. That is, the inflow port 33-1 and the outer pipe 44 are supplied from the inflow port 34 of the two-way switching valve body 33.
And the inner pipe 45, and is ejected from the outlet 46-1 of the tip cap 46 into the salt container 47, and the salt 48 is discharged.
And flows upward through the outlet pipe 46-1 as a saline solution through the inner pipe 45 again.
Through the outlets 40-4, 40-5, and 40-1, and from the outlet metal 35 to the water softener through the conduit 2. This salt solution is regenerated by flowing it through an ion exchange resin. (FIG. 11) shows an inverted type of the present salt regenerator, and shows a cross-sectional view thereof. Since the salt container 47 is inverted, tap water is spouted upward to dissolve the salt 48 and send it to the water softener as a salt solution. Therefore, the outer pipe 49 and the inner pipe 50 are as shown in FIG. It is shorter than the inner and outer pipes 45 and 44 of the upright type salt regenerator. The operation is the same as that of the upright type salt regenerator (FIG. 5), and the description is omitted. This inverted salt regenerator is convenient when it is fixed and installed on a platen 32 or the like, for example, on a sink.
(FIG. 12) and (FIG. 13) are enlarged cross-sectional views of the tip cap portion 46 of the outer pipe 44 and the inner pipe 45. FIG. 12 shows a state in which the tip cap 46 is completely screwed into the screw portion 44-1 of the outer pipe to reduce the dimension of L-1. The tap water flowing between the outer pipe 44 and the inner pipe 45 flows separately into an upward flow inside the inner pipe 45 and a flow spouting into the salt container from the outlet 46-1 of the tip cap 46. (FIG. 13) loosens the tip cap 46 with respect to the screw portion 44-1 of the outer pipe, and reduces the dimension of L-2 (FIG. 1).
This is a state that is larger than L-1 in 2). As in the state of FIG. 12, the tap water flowing between the outer pipe 44 and the inner pipe 45 flows upward in the inner pipe 45 and flows out of the tip cap 46 into the salt container. Although the flow is divided into the jet flow, the flow amount of the upward flowing water in the inner pipe 45 is larger in the state of FIG. 13 than in the state of FIG. 12, and accordingly, the flow jetted into the salt container is smaller. This means that the salt solution sent to the water softener is lower in FIG. 13. Thus, the tip cap 46 is rotated forward and reverse to change the position, that is, L-1.
By changing the size of, the concentration of the saline solution can be changed. The fact that the salt solution concentration can be easily changed is very convenient because the ion exchange resin can be regenerated in an optimum state.

(FIG. 14) When the salt container cap 42 of the present salt regenerator (upright type) of FIG. 5 is rotated in the reverse direction to remove the so-called salt cartridge together with the salt container 47,
At the same time, a cross-sectional view when the two-way switching valve 40 is rotated, pushed downward, and switched to a direct flow path is shown. 5
1 is a blind lid which is tightened to avoid dust. The flow of tap water flows as indicated by the arrow, that is, enters through the inlet port 34 of the two-way switching valve body 33, passes through the inflow port 33-1 and the flow hole 40-1 of the two-way switching valve 40, and passes through the outlet port 35. The water is then discharged from the pipe 2 directly into the water softener, where it is softened by the ion exchange resin. (FIG. 15) is a salt container cap 4 of the present salt regenerator (inverted type) of (FIG. 11).
When the so-called salt cartridge is removed together with the salt container 47, the two-way switching valve 40 is simultaneously rotated.
Is rotated and pushed upward to show a cross-sectional view when switching to a flow path in the direct direction. A blind lid 51 is tightened to prevent dust. Tap water flows as indicated by the arrow, and is sent directly to the water softener where it is softened with ion exchange resin.

The salt regenerator of the present invention has the following effects. (1) Even a water softener having no function of regenerating with a saline solution can be easily attached and provided with a regenerating function. (2) It can be easily attached to a water softener having a regeneration function, and the regeneration operation can be simplified. (3) It is convenient because a salt cartridge containing a previously set salt can be directly attached instead of a salt solution. (4) When the salt container becomes transparent, it indicates that the regeneration is completed, which is convenient. (5) Since the structure switches the two-way switching valve in synchronization with the attachment / detachment of the salt cartridge, it is very convenient and there is no fear of erroneous operation. (6) As shown in FIG. 4, the present salt regenerator can be installed near the water tap so that replacement of the salt cartridge can be facilitated. (7) The salt solution concentration can be easily changed by adjusting the tip cap 46, which is very convenient. (8) As shown in (FIGS. 14 and 15), when the salt cartridge is removed and soft water is collected, it is very compact and convenient. (9) The structure is simple and inexpensive.
