Description

 5-way valve module for water softener {5-WAY VLAVE MODULE USED IN SOFT WATER APPARATUS}

The present invention relates to a five-way valve module for a softener, and more particularly, is composed of an upper plate and a lower plate which are in close contact with each other up and down, and configured to change a flow path according to a rotation angle of the upper plate. It relates to a five-way valve module for a softener that can maintain the airtightness of the upper plate and the lower plate.

Currently, water softeners installed in homes or offices have a basic function of chemically converting hard water ions contained in tap water into softened water.

In general, tap water (hard water) contains a large amount of chlorine used in the purification process, and also contains various heavy metals (ions) such as iron, zinc, lead, and mercury, which are harmful to humans due to deteriorated pipes and water pollution. . Such tap water is not fatal to the human body, but when used as it is when washing the skin, the metal ions contained in the water and the fatty acids of the soap are combined to make metallic foreign substances. It causes skin diseases or accelerates aging of the skin.

Therefore, in order to prevent this, a water softener is developed to pass the tap water through the Na + type strong acid cation exchange resin to exchange the hardness components Ca2 + and Mg2 + with Na + in the resin to make soft water, which is mainly used for cleaning. .

The water softener has the principle of softening by replacing calcium ions and magnesium ions contained in hard water with sodium ions (Na +). For this purpose, a soft water container containing an ion exchange resin of a special high molecular compound containing sodium ions is an essential component. And a regeneration vessel containing ion exchange resin regenerators such as salt which, when dissolved in water, produces sodium ions.

That is, the water softener continuously generates tap water by contacting the ion exchange resin by continuously passing tap water into the soft water container in a state where a large number of fine ball-shaped ion exchange resins are stored in the soft water container. Since Na + is greatly reduced by continuous contact with tap water, salt water consisting of NaCl component is introduced into the soft water tank in order to preserve it.

Conventional water softeners generally include a soft water container including an ion resin for converting raw water supplied from the outside into soft water, and a salt-filled regeneration container for regenerating water for regenerating the ion resin when the ion resin is degraded. .

Hereinafter, a method of maintaining the airtightness of the ceramic upper plate 240 and the ceramic lower plate 230 in the water softener five-way valve module 200 will be described with reference to FIGS. 4 and 5.

Referring to FIG. 4, the check valve 290 is disposed in the hydraulic pressure control unit 226. As described above, since the hydraulic pressure control opening 226 is connected to the cold water inlet 223, the raw water is introduced through the cold water inlet 223 regardless of the mode. Thus, raw water may be supplied to the valve body 220 due to the check valve 290 in the hydraulic pressure control unit 226. Therefore, the space portion 227 of the valve body 220 sealed by the body cover 250 is always filled with raw water. On the other hand, the check valve 290 is a known component and description thereof will be omitted.

At this time, the introduced raw water fills the upper portion of the ceramic upper plate 240 so that the pressure of the water pressurizes the ceramic upper plate 240 in the downward direction, thereby maintaining airtightness of the ceramic upper plate 240 and the ceramic lower plate 230.

Specifically, the ceramic upper plate 240 is formed with a stepped portion 246 which is formed to be stepped at a constant height along the circumference. When the raw water fills the space inside the ceramic upper plate 240 formed by the stepped portion 246, the pressure of the water presses the ceramic upper plate 240 in a downward direction, thereby the ceramic upper plate 240. And airtightness between the ceramic lower plate 230 can be maintained.

On the other hand, when the force that the ceramic upper plate 240 presses the ceramic lower plate 230 becomes too large, and thus the torque acting on the ceramic lower plate 230 becomes large, the ceramic upper plate 240 can rotate smoothly. There will be no. Therefore, in order to prevent this, a center hole 243 penetrating the ceramic upper plate 240 is formed at the center of the ceramic upper plate 240. Therefore, by reducing the cross-sectional area of the ceramic upper plate 240 to which the pressure of water present in the space formed by the stepped portion 246 acts, the torque acting on the ceramic lower plate 230 can be reduced.

In addition, the ceramic lower plate 230 is stepped to a predetermined height along the circumference of the first step portion 236a and the plurality of flow path holes 231 to 235 which are formed to be stepped at a constant height along the circumference of the ceramic lower plate 230. The third stepped portion 236b, which is formed, and the third stepped portion 236c which are formed at a predetermined height on a circumference with respect to the center of the ceramic lower plate 230, and are adjacent to the second stepped portion 236b. Is formed.

When the cold water fills the space formed by the first, second, and third stepped portions, the cold water fills up between the ceramic upper plate 240 and the ceramic lower plate 230, and the pressure of the water is lowered from the ceramic upper plate 240. In pressing up, thereby causing the ceramic upper plate 240 to cancel the force to press the ceramic lower plate 230. Therefore, the torque acting on the ceramic lower plate 230 can be reduced.

Due to this structure, the ceramic upper plate 240 and the ceramic lower plate 230 are kept airtight without a separate component, and the ceramic upper plate 240 can be smoothly rotated on the ceramic lower plate 230. In addition, it is possible to reduce the sizes of the ceramic upper plate 240 and the ceramic lower plate 230.

The DC gear motor 271 is preferably applied as a step motor that rotates the ceramic upper plate 240 by an angle set in each mode, and rotates the pinion gear 273 coupled to the motor drive shaft 272.

The pinion gear 273 is meshed with the gear 274, which causes the gear 274 to rotate as the pinion gear 273 rotates.

The gear 274 is coupled to the upper side of the body cover 250, and rotates the rotating shaft 275 as the gear 274 rotates.

The rotary shaft 275 is coupled to the ceramic top plate 240, wherein one or more grooves 248 and 249 are formed on the circumference of the ceramic top plate 240, and one or more protrusions 275a are formed on the bottom of the rotary shaft 275. 275b are formed so that one or more grooves 248 and 249 of the ceramic top plate 240 are inserted into and coupled to the protrusions 275a and 275b of the rotary shaft 275. Due to this coupling, as the rotary shaft 275 rotates, the ceramic top plate 240 also rotates. Therefore, the hot water inflow flow path 231, the hot water outflow flow path 232, the cold water inflow flow path 233, and the cold water outflow flow path 234 of the ceramic lower plate 230 according to the rotation angle of the ceramic upper plate 240. And two or more of the reclaimed raw water inlet flow paths 235 can be selectively communicated with each other.

In addition, the cold water inlet flow path 233 and the cold water outlet flow path 234 is in communication with each other, the cold water flowing through the cold water inlet flow path 233 is discharged to the cold water outlet flow path 234.

Referring to FIG. 6B, in the [regeneration mode] , the flow path groove 241 is positioned only above the hot water discharge flow path hole 232, and the flow path groove 242 is the cold water flow path hole 233 and the regeneration raw water flow path hole. 235 is located above.

In this case, hot water introduced through the hot water inflow passage hole 231 is blocked by the ceramic upper plate 240 so that it cannot be introduced any more. On the other hand, the cold water inlet flow path 233 and the regeneration raw water inlet flow path 235 is in communication with each other, and the cold water flowing through the cold water inlet flow path 233 is discharged to the regeneration raw water inlet flow path 235. In this case, the cold water discharged into the regeneration raw water inflow passage hole 235 is introduced into the regeneration tank (not shown) through a separate pipe.

Referring to FIG. 6C, in the [stop mode] , the flow path groove 241 is positioned only above the hot water inlet flow path 231, and the flow path groove 242 is positioned only above the cold water discharge flow path hole 234.
