Gravity type WATER SOFTENER HAVING AUTO REVIVAL FUNCTION AND AUTO REVIVAL METHOD FOR THE SAME}

The present invention relates to a method for automatically regenerating a gravity type automatic regeneration water softener and a gravity type automatic regeneration water softener, and more particularly, to locate a regeneration tank on an upper side of an ion exchange resin tank and between the regeneration tank and the ion exchange resin tank in six directions. The present invention relates to a method for automatically regenerating a gravity type automatic regeneration water softener and a gravity type automatic regeneration water softener where a valve module is positioned so that regeneration water generated in a regeneration tank can be introduced into an ion exchange resin tank through the six-way valve module without additional power. .

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 components 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. have. 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 a metallic foreign substance. 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 are generally filled with a water tank containing an ion exchange resin for converting raw water supplied from the outside into soft water, and filled with salt for supplying regeneration water for regenerating the ion exchange resin when the performance of the ion exchange resin is degraded. It is equipped with a recycling container.

Conventionally, in order to regenerate the ion exchange resin in the soft water tank, a separate power source is used to introduce the brine in the regeneration water tank into the soft water tank including the ion exchange resin to recycle the ion exchange resin and discharge it to the outside. As a separate power source is used, there is a problem in that the composition of the product is complicated and the overall volume of the product is increased.

In addition, conventionally, for gravity automatic regeneration, the general method is that the brine of the regeneration bottle is directly obtained by a soft water tank containing an ion exchange resin. For this method, a check valve is installed in the flow path between the regeneration tank and the soft water tank so that the water pressure of the soft water tank is not lowered in normal use. However, according to the conventional method, when the check valve malfunctions due to the durability of the check valve, there is a problem that it is directly connected to leakage of regeneration water.

< Description of Structure of Gravity Automatic Regeneration Water Softener 400>

1 is a perspective view of a gravity type automatic regeneration water softener 400 according to an embodiment of the present invention, Figure 2 is an exploded perspective view of the gravity type automatic regeneration water softener 400, Figure 3 is a schematic diagram of a gravity type automatic regeneration water softener 400. . On the other hand, Figures 1 and 2 note that the flow path is omitted to explain the structure of the gravity type automatic regeneration water softener (400).

1, 2 and 3, the gravity type automatic regeneration water softener 400 is the first and second ion exchange resin tank (100a, 100b), 5-way valve module 200, 6-way valve module 300 And a regeneration tank 410 and reduced pressure flow sensors 430a and 430b.

The first and second ion exchange resin tanks 100a and 100b are filled with ion exchange resins capable of converting raw water supplied from the outside into soft water. In addition, it is in communication with the five-way valve module 200 and the six-way valve module 300 to be described later. Meanwhile, the first and second ion exchange resin tanks 100a and 100b may be detachably inserted into the tank connectors 160a and 160b, respectively.

The regeneration tank 410 is located above the first and second ion exchange resin tanks 100a and 100b to store a regenerant such as salt. Such a regenerant may be any one of powder, tablet, and block. Preferably, the block type salt may be stored because the volume is the highest when the block is used. 1 shows a regeneration tank 410 in which block salt is located, and FIG. 2 shows a regeneration tank 410 in which no block salt is located therein.

In addition, a flow guide 411 and a drain wall 412 may be provided in the regeneration tank 410, and the drain wall 412 converts the regeneration tank 410 into the drain area 413 and the regeneration area 414. Separate. In FIG. 2, the flow guide 411 is omitted.

When the water pressure of the raw water supplied to the regeneration tank 410 is high, more raw water is introduced into the regeneration tank 410 for a period of time as compared to the case where the water pressure is low to generate more regeneration water than necessary, or more regeneration agent than necessary. Waste or supplied raw water or generated regeneration water may overflow the regeneration tank 410. To prevent this, the flow path guide 411 is adopted. When the water pressure of the raw water supplied is high, the flow path 411 touches the flow path 411 so that a part of the flow flows directly into the drainage area 413 instead of the regeneration area 414. 12) it can be drained to the outside so as not to waste regenerant. As a result, the amount of raw water supplied into the regeneration area 414 can be kept constant, waste of regenerant can be reduced, and overflow of raw water in the regeneration tank 410 can be prevented.

In addition, when the raw water supplied to the regeneration area 414 or the regeneration water regenerated in the regeneration area 414 is excessive, the drainage wall 412 flows over the drainage area 413 to be drained to the outside through the overflow flow path 12. Can be. In this manner, excessively supplied raw water or excessively generated regenerated water may prevent overflow of the regeneration tank 410.

The five-way valve module 200 serves to switch the flow path in the soft water mode or the regeneration mode to be described later, the raw water inlet flow paths (1, 2) in communication with the water supply (not shown) for supplying hot and cold water, Raw water supply passages 3 and 4 communicating with the lower sides of the first and second ion exchange resin tanks 100a and 100b, respectively, and a regeneration raw water inflow passage 5 communicating with the regeneration tank 410 are provided.

The six-way valve module 300 serves to switch the flow path in the soft water mode or the regeneration mode to be described later, and the regeneration water supply passage 6 communicating with the regeneration tank 410 and the upper side of the first ion exchange resin tank 100a. A first regeneration water inflow passage 7 communicating with the first regeneration water flow passage 9 and a second ion exchange resin tank 100b communicating below the first ion exchange resin tank 100a. A second regeneration water inflow passage 8, a second regeneration water discharge passage 10 communicating with the lower side of the second ion exchange resin tank 100b, and a discharge passage 11 communicating with the outside are provided. On the other hand, the six-way valve module 300 is located between the regeneration tank 410 and the five-way valve module 200.

The above-mentioned configuration of the five-way valve module 200 and the six-way valve module 300 is sufficient to have a configuration capable of selectively opening or closing the flow paths 1 to 12 by a drive motor (not shown) and in particular Note that it is not limited.

The pressure reducing flow sensors 430a and 430b are positioned below the first and second ion exchange resin tanks 100a and 100b, respectively, and the hot water introduced into the first and second ion exchange resin tanks 100a and 100b, respectively. Cold water can be maintained at a constant pressure, and cumulative water flow can be checked. Since the reduced pressure flow sensor is a known component, a description thereof will be omitted.

The gravity automatic regenerative water softener 400 controls the operation mode of the water softener by selectively opening or closing the flow paths 1 to 12 of the 5-way valve module 200 and the 6-way valve module 300. .

In particular, the cold water flows into the regeneration tank 410 through the raw water inflow channel 2 and the regeneration water inflow channel 5 due to the hydraulic pressure of the power outlet. The salt in the regeneration tank 410 is dissolved in the cold water introduced into the regeneration tank 410 to generate regeneration water having a predetermined concentration. The generated regeneration water is present in the regeneration water supply flow path 6 and the first regeneration water because of the gravity without any power since the regeneration tank 410 is located above the first and second ion exchange resin tanks 100a and 100b. The ion exchange resin in the first ion exchange resin tank (100a) is recycled through the inflow passage (7), the first regeneration water outlet passage (9), and the discharge passage (11) and discharged to the outside, or the regeneration water supply passage (6). In addition, the second regeneration water inflow passage 8, the second regeneration water discharge passage 10, and the discharge passage 11 pass through the ion exchange resin in the second ion exchange resin tank 100b and are discharged to the outside.

<Description of the operation principle of the gravity type automatic regeneration water softener 400>

Hereinafter, an operation mode of the gravity type automatic regeneration water softener 400 will be described in detail with reference to FIG. 4. 4 is a schematic diagram illustrating whether water flow paths 1 to 12 are opened or closed and water flows according to the mode of the gravity type automatic regeneration water softener 400.

4A illustrates whether the flow paths 1 to 12 are opened or closed and water flows when the gravity type automatic regeneration water softener 400 is in [soft mode].

In the [soft mode] , only the raw water inflow passages 1 and 2 and the raw water supply passages 3 and 4 of the five-way valve module 200 are opened, and the regeneration raw water inflow passage of the five-way valve module 200 ( 5) and the flow path of the six-way valve module 300 is closed.

Therefore, the hot water and the cold water introduced into the first and second ion exchange resin tanks 100a and 100b through the raw water inflow passages 1 and 2 and the raw water supply passages 3 and 4, respectively, are first and second. 2 It is converted into soft water and discharged by the ion exchange resin in the ion exchange resin tanks 100a and 100b.

[Playback Mode] is It is composed of [the replenishment tank replenishment mode], [regeneration water generation mode], [tank pressure relief mode], [regeneration water input mode] and [rinse mode], these modes are performed sequentially.

4B shows the flow of water and whether the flow paths 1 to 12 are opened or closed when the gravity type automatic regeneration water softener 400 is in the replenishment tank raw water replenishment mode.

In the raw water replenishment mode in the regeneration tank, only the raw water inflow passages 2 and the regeneration raw water inflow passage 5 which supply cold water among the raw water inflow passages 1 and 2 of the five-way valve module 200 are opened. The remaining flow path of the 5-way valve module 200 and the flow path of the 6-way valve module 300 are all closed. This state is preferably maintained for about 1 minute to 2 minutes, more preferably 1 minute 30 seconds, it is noted that this time may be changed depending on the capacity of the regeneration tank 410 and the like.

Therefore, the cold water flows into the regeneration tank 410 through the raw water inflow channel 2 and the regeneration raw water inflow channel 5 due to the hydraulic pressure of the power outlet.

Raw water supplied excessively to the regeneration tank 410 may be directly drained to the outside through the over-flow passage 12.

4C shows whether the flow paths 1 to 12 are opened or closed and water flows when the gravity type automatic regeneration water softener 400 is in the regeneration water generation mode.

In the [regeneration water generation mode] , all the flow paths of the five-way valve module 200 and the six-way valve module 300 are closed. It is preferable that such a state is maintained for about 12 to 20 minutes, but may be changed depending on the required concentration of regeneration water.

Therefore, the salt in the regeneration tank 410 is dissolved in the cold water introduced into the regeneration tank 410 to generate regeneration water having a predetermined concentration.

The excessively generated regeneration water may be drained to the outside through the overflow wall 12 through the drain wall.

FIG. 4D shows the flow of water and whether the flow paths 1 to 12 are open or closed when the gravity type automatic regeneration water softener 400 is in the pressure relief mode in the tank.

In the tank pressure relief mode , only the first regeneration water outlet passage 9 and the discharge passage 11 of the six-way valve module 300 are opened, and the flow path and the six-way valve module 300 of the five-way valve module 200 are opened. ), The remaining flow paths of the six-way valve module 300 are completely closed or only the second regeneration water discharge flow path 10 and the discharge flow path 11 of the six-way valve module 300 are opened. The remaining flow path of 300 is completely closed. Note that this state is maintained for 10 seconds to 1 minute, more preferably about 20 seconds, but may be changed depending on the sizes of the first and second ion exchange resin tanks 100a and 100b.

Therefore, the soft water in the first ion exchange resin tank 100a is discharged to the outside to remove the pressure in the first ion exchange resin tank 100a. Alternatively, the soft water in the second ion exchange resin tank 100b is discharged to the outside to remove the pressure in the second ion exchange resin tank 100b. Note that this process may occur simultaneously in the first and second ion exchange resin tanks 100a and 100b.

On the other hand, the mode is a mode for inputting the regeneration water without additional power in the regeneration water input mode to be described later.

4E shows the flow of water and whether the flow paths 1 to 12 are opened or closed when the gravity type automatic regeneration water softener 400 is in the regeneration water input mode.

In the [regeneration water input mode] , the flow path of the five-way valve module 200 is completely closed, and the regeneration water supply passage 6 and the discharge passage 11 of the six-way valve module 300 are opened. Further, the first regeneration water inflow passage 7 and the first regeneration water inflow passage 9 of the six-way valve module 300 are opened or the second regeneration water inflow passage 8 and the second of the six-way valve module 300 are opened. The regeneration water flow path 10 is opened. It is maintained in this state for about 10 to 15 minutes, more preferably about 13 minutes, but this time is the size in the first and second ion exchange resin tank (100a, 100b), the first and second ion exchange resin tank Note that the amount can be changed depending on the amount of ion exchange resin in (100a, 100b) and the like.

Therefore, the regeneration water generated in the regeneration tank 410 flows into the first ion exchange resin tank 100a through the regeneration water supply passage 6 and the first regeneration water inflow passage 7, and the first ion exchange resin tank The ion exchange resin present in the 100a is regenerated and discharged to the outside through the first regeneration water outlet passage 9 and the discharge passage 11. Alternatively, the regeneration water generated in the regeneration tank 410 flows into the second ion exchange resin tank 100b through the regeneration water supply passage 6 and the second regeneration water inflow passage 8, and the second ion exchange resin tank 100b. Regenerated ion exchange resin in the) and is discharged to the outside through the second regeneration water outflow passage 10 and the discharge passage (11). Note that this process may occur simultaneously in the first and second ion exchange resin tanks 100a and 100b.

4F shows the flow of water and whether the flow paths 1 to 12 are open or closed when the gravity type automatic regeneration water softener 400 is in the rinse mode.

In the "rinse mode" , the raw water inflow passages 1 and 2 and the raw water supply passages 3 and 4 of the five-way valve module 200 are opened, and the regeneration raw water inflow passage 5 is closed. In addition, the first regeneration water outlet passage 9 and the discharge passage 11 are opened or the second regeneration water outlet passage 10 and the discharge passage 11 are opened. In this state, it is maintained for about 4 to 6 minutes, more preferably about 5 minutes, but such time depends on the size in the first and second ion exchange resin tanks 100a and 100b, the time for setting the [regeneration mode], and the like. Note that it may change.

Therefore, the hot water introduced into the first ion exchange resin tank 100a through the raw water inflow passage 1 and the raw water supply passage 3 removes the regeneration water remaining in the first ion exchange resin tank 100a, thereby removing the first water. It is discharged to the outside through the regeneration water outflow passage 9 and the discharge passage (11). Alternatively, the cold water introduced into the second ion exchange resin tank 100b through the raw water inflow passage 2 and the raw water supply passage 4 removes the regeneration water remaining in the second ion exchange resin tank 100b and discharges the second regeneration water. It is discharged to the outside through the flow path 10 and the discharge flow path (11). Note that this process may occur simultaneously in the first and second ion exchange resin tanks 100a and 100b.
