Definitions
- the regeneration tank is typically provided with an openable cap for charging a regeneration agent into the tank.
- raw water under pressure is contained in the regeneration tank, so that the interior of the regeneration tank is pressurized and it is difficult to open the cap because it is under pressure. Further, when the cap is opened, the cap may suddenly explode off due to the pressure and may injure a user.
- the present invention provides a water softener, which uses a timer having a timer spring and is configured such that a timer handle can be actuated by the timer spring, thus informing a user of both the current operation mode and the progress of regeneration.
- the present invention provides a water softener, in which resin tanks are coupled to each other in parallel.
- the water softener may be a water pressure regenerated type water softener.
- the separator unit may include a plurality of slits, which open towards the resin tank inlet conduit, and an axial channel in which the slits are located.
- the regeneration tank may include a regeneration tank cap having a shaft, and a drain valve for drawing regeneration water from the regeneration tank.
- One end of the shaft may be connected to the regeneration tank cap, while a drain cap may be provided on the other end of the shaft.
- the drain cap closes the drain valve.
- the shaft is moved upwards by the shaft spring, so that the drain cap can open the drain valve.
- the water softener may further include a soft water outlet conduit, which communicates with the resin tank unit at one end thereof, and an integrating flowmeter provided on the soft water outlet conduit.
- the water softener of the present invention allows a user to effectively view the progress of operation mode and the progress of regeneration mode. Further, the water softener does not use electric signals, thus being free from electrical shorts and reducing the cost of installation.
- the regeneration tank cap can be easily opened and, at the same time, the regeneration tank cap can be simply opened by one motion without separately opening a drain valve, unlike conventional water softeners. Further, the present invention can prevent sudden removal of the regeneration tank cap, thus preventing users from being injured.

- Fig. 7 is an exploded perspective view of the timer control valve of Fig. 5;
- Fig. 9 is a schematic diagram illustrating operation of a valve control unit of the present invention.
- Fig. 2 through Fig. 4 are perspective views of the water softener according to the present invention, from which the outer casing 100 is omitted.
- Fig. 2 is a front perspective view
- Fig. 3 is a rear perspective view
- Fig. 4 is a sectional perspective view, which is viewed from the same viewing direction as that of Fig. 2.
- the filter unit 300 functions to filter the raw water flowing thereto through the filter unit inlet conduit 310. Filtered raw water flows into a resin tank through a resin tank inlet conduit 520.
- the integrating flowmeter 600 is installed on the soft water outlet conduit 610 and allows a user to easily view the amount of outlet soft water (see Fig. 1). Therefore, the user can be informed of the total amount of outlet soft water by viewing the integrating flowmeter 600 and can determine the time when regeneration mode, wherein the ion exchange resin is regenerated, begins.
- the resin tank unit 500 uses a plurality of resin tanks 500a, 500b and 500c coupled to each other in parallel. Due to the parallel coupling of the resin tanks, the length of the flow conduit through which the soft water flows prior to being distributed can be reduced, thus realizing easy control of the temperature of the soft water and solving the problems experienced with the installation of a large-sized water softener.
- the lower valve body 240 is a circular body having predetermined thickness and made of a ceramic material.
- a plurality of flow holes are formed through the lower valve body 240.
- the flow holes comprise a soft water hole 241, a raw water hole 242 and a regeneration hole 243.
- the soft water hole 241 and the raw water hole 242 may have a sectorial shape or a triangular shape formed around the center of the lower valve body 240.
- the sectorial or triangular shape of the flow holes of the present invention reduces the surface area of the lower valve body 240, thus realizing compactness of the lower valve body 240.
- the regeneration hole 243 may be formed as an arc-shaped hole having a predetermined width.
- the timer control valve 200 guides the raw water to the filter unit inlet conduit 310.
- the filter unit 300 the raw water is filtered and the filtered raw water is, thereafter, evenly distributed to the respective resin tanks 500a, 500b and 500c through the resin tank inlet conduit 520.
- the timer control valve 200 guides the raw water to the raw water outlet conduit 120 and, thereafter, the raw water is distributed to the user through the distribution conduit 620.
- the flow sequence of water in soft water mode is as follows.
- the mark - denotes the flow of water:
- the flow sequence of water in the raw water mode is as follows:
- the user rotates the valve shaft 290 to start the regeneration process.
- the user rotates the valve shaft 290 in a counterclockwise direction, thus bringing the second teeth 294 of the second gear 292 into engagement with the first teeth 234 of the first gear 232.
- the second teeth 294 have both a first point 296, at which the second gear 292 initially engages with the first gear 232, and a second point 297 at which the second gear 292 completes its engagement with the first gear 232.
- the second gear 232 rotates in a clockwise direction from the first point 296 so that the timer spring of the timer 230 is contracted. Thereafter, the rotation of the valve shaft 290 is stopped before the first gear 232 passes over the second point 297.
- the above-mentioned process is a process preceding the execution of regeneration. Due to the restorative force of the contracted timer spring, both the first gear 232 and the second gear 292 can rotate, so that the upper valve body 250 can be rotated relative to the lower valve body 240 by a predetermined angle.
