Abstract

PURPOSE:To provide a water softener for household which is capable of adjusting a raw water inflow rate to a regenerating agent tank and preventing back flow and diffusion of a regenerated liquid to a raw water primary side at the time of dissolving a regenerating agent by passing the raw water through the regenerating agent tank. CONSTITUTION:The bottom of the regenerating agent tank 3 is provided with a raw water inflow part 10. This raw water inflow part 10 is formed as a ball type flow rate control check valve provided with a valve chamber 14 having valve seats 15 and 16 in a spherical surface shape on the upper and lower surfaces and a ball 17 housed in this valve chamber 14. A bypass path 18 for making the regenerating agent tank 3 communicate with the valve chamber 14 is formed at the valve seat 15 formed on the upper surface of the chamber 14. Then, the supply of a proper volume of the raw water from this bypass path 18 to the regenerating agent tank 3 is possible at the time of regeneration. The diffusion of the regenerated liquid in the regenerating agent tank 3 to the raw water primary side is prohibited at the time of stopping the regeneration.

2. Description of the Related Art Water softeners for softening raw water have become widespread in homes and offices. In recent years, however, especially in domestic water softeners, a regenerant is produced by dissolving a regenerant in a separate container. From the water softener of the method in which the agent solution (hereinafter referred to as "regeneration solution") is poured into the ion-exchange resin unit for regeneration, a regenerant tank is provided in the water passage to allow the raw water to pass through to dissolve the regenerant and release the ions. A water softener that regenerates the replacement resin unit is about to replace the mainstream. Hereinafter, the structure of the regenerant tank provided in the conventional water softener will be described with reference to the drawings.

FIG. 4 is a sectional view of a regenerant tank (hereinafter simply referred to as "tank") provided in a conventional water softener. The tank 3 is connected to a regeneration water passage of a water softener (not shown) by an inlet 1 of raw water and an outlet 2 of regeneration liquid. A filter cloth 5 is arranged in the tank 3 so as to cover the inflow port 1 and the outflow port 2 so that the regenerant 6 mainly made of powder contained therein does not flow out. The regenerant 6 is introduced by removing the lid 4 of the tank 3.

However, in the conventional structure as described above, when the regenerant 6 is dissolved to regenerate the ion-exchange resin, the concentration and the dissolution rate of the regenerant 6 largely depend on the inflow amount of raw water. To be done. That is, when the flow rate of raw water is large, the regenerant 6 is immediately dissolved, and since the amount of inflowing water is large, only a regenerant solution having a relatively low concentration can be obtained. Since it is necessary to pass the liquid through the liquid for a predetermined time, the conventional method has a problem that it is difficult to obtain high regeneration efficiency.

2 and 3, a ball type flow control check valve 10 as a raw water inflow portion is provided at the bottom of the tank 3.
Is provided. This ball type flow control check valve 10
Has a main body 12 fitted to a protruding portion 11 provided on the bottom of the tank 3. A valve hole 13 communicating with the tank 3 is formed inside the main body 12, and the valve chamber 1 is provided in the middle of the valve hole 13.
4 are formed. The upper and lower surfaces of the valve chamber 14 are spherical valve seats 15 and 16, respectively, and a ball 17 is housed inside thereof. Also, the valve seat 15 on the upper surface side
The bypass passage 18 is formed in a groove shape so as to extend along the surface of the. The bypass passage 18 connects the inside of the tank 3 with the valve chamber 14. Ball 17 as shown in FIG.
In the state where the water is in close contact with the valve seat 15, the raw water flows into the tank 3 through the bypass passage 18 as shown by the arrow in the figure.

Therefore, when raw water flows into the valve hole 13 from below, the ball 17 is pushed up by the raw water and comes into close contact with the valve seat 15 on the upper surface.
It flows through 8 into the tank 3. The bypass passage 18 is formed to have a size capable of obtaining a required flow rate, and therefore the amount of raw water required for regeneration flows into the tank 3 to dissolve the regenerant 6 and become a regenerant liquid, which is discharged from the outlet 2. It is discharged to the ion exchange resin unit 7.

When the raw water stops flowing, the ball 17 falls by its own weight and lands on the valve seat 16 on the lower surface to close the valve hole 13, which is different from the structure in which the diameter of the raw water inlet is simply reduced. There is little risk of clogging. Further, the ball 17 lands on the valve seat 16 on the lower surface to completely close the valve hole 13,
The diffusion of the regenerant 6 to the primary side of the raw water can be surely prevented.
