Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an RO filter for purifying water,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a purified water amount control valve for purifying purified water and a concentrated water discharge amount control valve, more specifically, (Which means wastewater that can not be filtered by the RO filter), and a concentrated water discharge amount control valve.

In the general purification system equipped with the RO filter shown in FIG. 1,

A sediment filter 1 for filtering rust, soil, sand, and suspended solid matter contained in raw water (sewage water, ground water, etc.) flowing through a hose connected to a faucet,

A free carbon filter (2) for removing chlorine components, organic chemical substances and the like remaining in the water by the adsorption method of activated carbon,

A reverse osmosis membrane filter (RO filter) 3 for filtering bacteria, pollutants, inorganic substances, heavy metals and the like in the water by the polyamide composite membrane,

A post carbon filter (4) for treating the odor and gas components in the water to improve the water taste by water treatment;

An automatic shut-off valve (ASV) 6 for automatically shutting off the inflow of raw water into the water filter side when the constant of the storage tank 5 is set to a high level, provided on the downstream side of the sediment filter 1 ).

In the figure, reference numeral 7 denotes a flow restrictor for adjusting the amount of concentrated water so that the ratio of the purified water discharged from the RO filter 3 to the concentrated water is maintained at an arbitrary ratio (for example, 1: 3) )to be.

In other words, due to the characteristics of the RO filter, the amount of purified water (generally, 3: 1 ratio) discharged through the RO filter after passing through the RO filter is relatively small with respect to the inflow amount of the raw water flowing into the RO filter, Which has a very low disadvantage.

On the other hand, in the water purifier using the RO filter 3, the purified water amount purified by the RO filter 3 can be varied by the water temperature due to the cross-sectional area, water pressure or seasonal variation of the membrane of the RO filter 3.

Therefore, the purified water amount purified by the RO filter 3 can be varied according to the water temperature or water purifier specification condition due to the seasonal variation, so that the ratio of the concentrated water amount to the purified water amount is adjusted and used.

At this time, it is not easy for a consumer who is a non-specialist in a general home or office using a water purifier equipped with the RO filter 3 to control the amount of concentrated water discharged by controlling the opening amount of the waste water chamber 7 directly in accordance with seasonal variation.

Therefore, when a professional company that manages the water purifier controls the opening amount of the waste water chamber (7) in order to control the amount of concentrated water discharged, the cost of the business trip will be burdened by the consumer.

A wastewater saving water purification system is disclosed in Korean Patent Laid-Open Publication No. 10-2004-0024777 (published on March 22, 2004).

Therefore, the embodiment of the present invention is capable of easily confirming the amount of purified water discharged from the RO filter and confirming the purified water amount for the RO filter, which enables the non-specialist consumer to easily control the amount of concentrated water discharged according to the season, Control valves.

The embodiment of the present invention is characterized in that the concentrated water is not reused so that a purified water can be consumed and an RO filter that can prevent the RO filter performance generated during the process of re- The amount of water purified and the concentrated water discharge control valve.

In order to achieve the above and other objects of the present disclosure, according to one embodiment of the present disclosure,

A concentrated water discharge amount control valve of a water purifier including an RO filter, comprising:

A first water level indicating ball which is moved along an integer of the water flow path; and a second water level indicator which is disposed at one side of the water level indicator, And a first flow rate display unit that displays a constant flow rate by the movement of the first level indicator ball, the first flow rate display unit comprising: a first housing formed of a transparent body;

A first upper cap mounted at an upper end of the water passage;

A concentrated water flow passage formed integrally with or separated from the first housing and connected to the concentrated water inlet, the concentrated water outlet for discharging the concentrated water, the concentrated water flow passage for communicating the concentrated water inlet and the concentrated water outlet, And a second flow indicator which is formed on one side surface and which displays the concentrated water flow rate by the movement of the second water level indicator ball, A second housing;

A second upper cap mounted on the upper end of the concentrated water moving passage;

And an adjuster coupled to open and close the lower end opening of the concentrated water moving passage for varying the amount of concentrated water flowing into the lower opening according to the amount of rotation, Thereby providing a water discharge regulating valve.

According to the embodiment of the present invention configured as described above, the following advantages are obtained.

 Consumers can visually confirm the amount of purified water discharged from the RO filter, and the consumer who is a non-expert can easily adjust the condensed water discharge amount according to the season, thereby obtaining reliability and practicality.

In addition, since the concentrated water is not re-filtered, it is possible to drink purified water in a clean state, and the RO filter performance generated in the process of re-filtering the concentrated water is prevented from being lowered or the service life is shortened. The economic burden of frequent replacement can be reduced.

The second housing 22 further includes a fourth fit 37 for detachably connecting the hose connected to the counter base 39 of the sink to the concentrated water outlet 18 in a one-touch manner .

Hereinafter, examples of the use of the RO water purification amount confirmation and concentrated water discharge amount control valve according to one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 2 to 6, raw water such as tap water is sequentially purified by a sediment filter, a pre-carbon filter, an RO filter 35, and a post carbon filter 32 connected in series, And the concentrated water which is stored in the storage tank 40 and which has not been filtered by the RO filter 35 is thrown to the counterpart 39 of the sink is substantially the same as the purified water system shown in Fig. A detailed description thereof will be omitted.

The purified water purified by the RO filter 35 and then discharged is transferred to the post-carbon filter through the hose connected to the first pit 33 formed in the first housing 15, To the water inlet (10).

The purified water moved to the purified water inlet 10 is moved along the purified water passage 12 communicating with the purified water inlet 10 in the upward direction in the figure, that is, toward the first top cap 16, Is discharged from the first housing 15 through the purified water outlet 11 and the third pit 33 communicating with the upper end of the third pit 33 and then moved to the faucet 38 through the hose connected to the third pit 33.

When the purified water discharged from the RO filter 35 as described above passes through the purified water inlet 10 of the first housing 15 and is moved upward and upward along the purified water passage 12, The first level indicator ball 13, which is installed so as to have a buoyancy force, moves along the integer.

Therefore, when the first level indicator ball 13 having buoyancy is temporarily stopped at an arbitrary position in the constant flow passage 12, the user confirms the scale of the first flow indicator 14, It is possible to visually confirm the amount of purified water that is discharged and moves toward the faucet 38.

Meanwhile, the concentrated water that can not be filtered by the RO filter 35 flows into the concentrated water inlet 17 of the second housing 22 through the hose connected to the second pit 34 formed in the second housing 22 .

The concentrated water moved to the concentrated water inlet port 17 is moved in the upward direction in the figure, that is, toward the second upper cap 23 along the concentrated water flow passage 19 communicated with the concentrated water inlet port 17, The water is discharged from the second housing 22 through the concentrated water outlet 18 and the fourth pit 37 communicating with the upper end of the moving passage 19 and then transmitted through the hose connected to the fourth pit 37, (39).

As described above, the concentrated water that can not be filtered by the RO filter 35 passes through the concentrated water inlet 17 of the second housing 22, moves along the concentrated water flow passage 19 in the drawing and upward , The second level indicator ball 20, which is provided so as to have buoyancy in the concentrated water moving passage 19, moves along the concentrated water.

Therefore, when the second level indicator ball 20 having buoyancy is temporarily stopped at an arbitrary position of the concentrated water flow passage 19, the user confirms the scale of the second flow rate indicator 2, It is possible to visually confirm the amount of concentrated water discharged from the counter base 39 and moved toward the counter base 39 of the sink.

At this time, the user can easily adjust the amount of the condensed water that is not filtered by the RO filter 35 and is moved to the counter base 39 of the sink by the one-touch method according to the seasonal or raw water temperature.

When the concentrated water discharged from the RO filter 35 is filtered through the concentrated water inlet 17 of the second housing 22 and moved to the concentrated water flow passage 19, The amount of concentrated water can be adjusted in accordance with the rotating direction of the regulating opening 24 mounted on the regulating opening 24.

That is, when the knob 30 formed on the outer end of the regulating opening 24 is gripped to rotate the rotating body 31 in the clockwise direction, the spool 29 connected to the inner end of the rotating body 31 is rotated by the body 28, the opening amount of the inflow hole 27 formed in the radial direction of the body 28 can be adjusted to be reduced as the sliding movement is performed in the right direction in the drawing.

Accordingly, as the opening of the inflow hole 27 is reduced by the movement of the spool 29, the amount of concentrated water flowing through the concentrated water inlet port 17 and moved to the concentrated water flow passage 19 can be reduced.

The spool 29 connected to the inner end of the rotating body 31 is rotated in the counterclockwise direction by rotating the rotating body 31 in the counterclockwise direction by gripping the handle 30 formed at the outer end of the adjusting hole 24, The opening amount of the inflow hole 27 formed in the body 28 in the radial direction can be maintained to be maximally opened as the body 28 is slid in the left direction in the drawing.

Accordingly, the amount of the concentrated water flowing into the second housing 22 through the concentrated water inlet 17 and moved to the concentrated water moving passage 19 can be relatively increased by securing the state in which the inflow hole 27 is maximally opened .

As described above, according to the present embodiment, the purified water purification volume for the RO filter and the condensed water discharge volume control valve allow the purified water purified by the RO filter 35 to flow through the purified water passage (not shown) of the first housing 15 The first flow indicator 14, which is indicated by an arbitrary position of the first level indicator ball 13 that maintains the buoyancy state by the purified water in the purified water passage 12 when the water level indicator 12 is moved toward the faucet 38, The amount of purified water can be visually confirmed.

When the concentrated water discharged from the RO filter 35 can not be filtered and is moved to the counter base 39 of the counterclockwise direction, The amount of opening of the inflow hole 27 communicated with the concentrated water flow passage 19 can be reduced or enlarged by the spool 29 connected to one end of the adjustment port 24, The amount of concentrated water that flows into the concentrated water inlet 17 of the second housing 22 and moves to the concentrated water moving passage 19 can be variably controlled by the amount of rotation of the regulating opening 24.

Therefore, the user can directly adjust the amount of condensed water that can not be filtered by the RO filter 35 depending on the water temperature of the raw water flowing into the season or the water purifier, by a one-touch method.
