Description

[0001] WATER TREATING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water treatment apparatus, and more particularly, to a water treatment apparatus that uses water of different water quality to increase water pressure.

The water treatment apparatus is a device that processes the inflow water and discharges it to the outside to supply it to the user. Such a water treatment apparatus includes at least one water filter to filter the incoming water and supply it to the user. In addition to the water purifier described above, there is also an ionizer for supplying carbon dioxide to the inflowed water and then supplying it to the user, or an electrolyzer for electrolyzing the inflowed water to supply the user with alkaline water and acid water.

On the other hand, there is an reverse osmosis filter as a water filter included in a water purifier for water treatment. When the water is introduced into the reverse osmosis filter, some of the water is filtered to become purified water, and the remaining water can not be filtered to be used for drinking water. And the purified water that is filtered by the reverse osmosis filter and discharged from the reverse osmosis filter becomes lower in pressure than the water that flows into the reverse osmosis filter. Further, the water purifier may include a water tank in which filtered purified water is introduced and stored.

When the reverse osmosis filter is used as one of the water purifiers in the water purifier, the purified water filtered by the reverse osmosis filter has a relatively low pressure even if it is stored in the water tank. Accordingly, there is a problem that the extraction position of the integer is limited when the integer is supplied to the user. For example, when the water discharge member such as a cock or faucet that is connected to a water tank and discharges the purified water stored in the water tank to the outside is located at a position lower than the low water level of the water tank, the purified water stored in the water tank is discharged to the outside Can be discharged.

In order to solve such a problem, a surge tank configured to maintain a predetermined pressure even if the purified water is introduced at a low pressure is used as a water tank. However, in such a case, since the reverse osmosis pressure acts on the reverse osmosis filter from the water tank serving as the surge tank, the flow rate of the purified water discharged from the reverse osmosis filter decreases and the filtration efficiency of the reverse osmosis filter decreases. In addition, there is a problem that if the raw water is not separately blocked after the full water, the living water is continuously generated.

Problems to be solved by the present invention are as follows.

First, the purified water is easily discharged to the outside.

Second, it maintains the proper water pressure regardless of the location of the water storage space.

Third, the back pressure is not applied to the filtration part.

Fourth, the flow rate of the filtered water is not reduced and the filtration efficiency is not lowered.

Fifth, the energy efficiency is increased by excluding the separate pressing member.

Sixth, the living water discharged from the reverse osmosis filter is recycled.

The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a water treatment apparatus comprising: a filtration unit for filtering raw water; And a reservoir for storing at least two kinds of water each having different water quality discharged from the filtration unit and forming a plurality of chambers in which the volume of one of the chambers is reduced when the volume of one of the two kinds of water is increased.

In addition, the water treatment apparatus according to an embodiment of the present invention includes a filtering unit for filtering raw water; A storage part for storing purified water discharged from the filtration part and having a movable partition wall formed therein; And a living water supply pipe connected to the storage unit to discharge the purified water stored in the storage unit by applying water pressure to the partition wall.

In addition, the water treatment apparatus according to the embodiment of the present invention includes: a filtration unit for discharging at least two kinds of water having different water quality; A purification chamber for storing purified water having a high degree of filtration among the water discharged from the filtration unit; A living water chamber for storing water having a filtration degree lower than that of water discharged from the filtration unit; And a partition wall for transferring the water pressure of the living water chamber to the purification chamber.

The details of other embodiments are included in the detailed description and drawings.

The present invention has the following effects.

First, even if the reverse osmosis filter is used, the purified water can be easily discharged to the outside.

Second, proper water pressure can be given to the water, so it is not necessary to limit the location of the water storage space.

Third, no back pressure acts on the filtration part.

Fourth, the flow rate of the discharged purified water is not reduced and the filtration efficiency is not lowered.

Fifth, the position of the water storage space can be freely determined, thereby increasing the space efficiency.

Sixth, the living water discharged from the reverse osmosis filter can be recycled to protect the water resources.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

The drain pipe (LD) may be provided with a life water valve (VLW). The drain pipe (LD) can be connected to a life water discharge pipe (LDS) connected to a channel switching valve (400) to be described later.

The living water discharged from the living water chamber 320 of the storage unit 300 and flowing through the inlet and outlet pipe LEI connecting the living water chamber 320 of the storage unit 300 and the flow path switching valve 400 is discharged And can be discharged to the outside through the piping (LDS) and the drain piping (LD). The purified water discharge pipe LE branched from the purified water supply pipe LPW may be connected to the flow path switching valve 400 to be described later so as to be connected to the water intake apparatus 500 such as a cock or a faucet. The water stored in the purified water chamber 310 of the storage unit 300 flows to the water intake apparatus 500 through the purified water supply pipe LPW, the purified water discharge pipe LE and the flow path switching valve 400, Lt; / RTI >

A second water filter 230 may be installed in the water discharge pipe LE. When the purified water stored in the purified water chamber 310 is discharged through the purified water discharge pipe LE, the filtered water can be filtered and discharged by the second purified water filter 230. The second water filter 230 provided in the water discharge pipe LE is not particularly limited and any well-known water filter may be used as long as it is a water filter capable of filtering water. The number of water filters provided in the purified water discharge pipe LE is not particularly limited, and any number may be used. The second check valve CV2 may be provided in the purified water discharge pipe LE between the branching point from the purified water supply pipe LPW and the flow path switching valve 400. [

The pressure of the part of the purified water discharge pipe LE between the second check valve CV2 and the water intake apparatus 500 and the pressure of the outflow pipe LCE connecting the flow path switching valve 400 and the water intake apparatus 500 So that a predetermined pressure can be maintained. When the purified water is stored in the purified water chamber 310 to be described later, the flow path switching valve 400 can continuously connect the inflow / outflow pipe LEI with the living water discharge pipe LDS.

The storage unit 300 may be connected to the filtering unit 200. The storage unit 300 may include a purified water chamber 310 and a living water chamber 320. The purified water in the purified water chamber 310 can be stored. The purified water stored in the purified water chamber 310 may be discharged from the purified water chamber 310.

The living water chamber 320 can store or discharge living water. To this end, the living water chamber 320 may be connected to an inlet / outlet pipe (LEI) connected to a channel switching valve 400 to be described later.

The storage unit 300 forms a plurality of chambers 310 and 320. The storage unit 300 stores water of different water quality. The plurality of chambers 310, 320 are formed to be pressure-transferable. If pressure is applied to any one of the chambers 310 and 320, the outer shape of the chambers 310 and 320 may be deformed. The plurality of chambers 310 and 320 can be deformed by the water pressure applied to the chamber.

However, it is preferable that the plurality of chambers 310 and 320 store water of different water quality so that water is not mixed. The partition wall 340 delivers pressure without passing water. For example, the barrier ribs 340 may be deformable in response to pressure. The partition wall 340 may be deformed to change the volume of another chamber as the pressure of one chamber increases. That is, even if the total volume of the storage unit 300 is fixed, the volume ratio between the plurality of chambers 310 and 320 can be changed due to the partition 340. Thus, as the volume of either chamber increases, the volume of the other chamber decreases by the same amount. As another example, the barrier ribs 340 may be movably disposed inside the storage portion 300. The partition wall 340 may move like a piston to change the size between the plurality of chambers 310 and 320.

The flow path switching valve 400 opens the life water discharge pipe (LDS) connected to the living water chamber 320 so that the water purification chamber 310 can freely expand when storing the purified water. The flow path switching valve 400 opens a living water supply pipe LLW connected to the living water chamber 320 by applying pressure to the water purification chamber 310 when the purified water is discharged. The purified water discharge pipe LE communicates with the purified water chamber 310 so that the pressure transmitted from the living water chamber 320 is transferred to the purified water flowing in the inside of the purified water discharge pipe LE, As shown in Fig.

The flow path switching valve 400 switches the flow path by using the pressure of the purified water discharge pipe LE as a power source. The purified water discharge pipe (LE) communicates with the purified water chamber (310). Therefore, the pressure of the purified water chamber 310 is transferred to the purified water discharge pipe LE. The flow path switching valve 400 drives the plunger 430 with the pressure transferred from the purified water chamber 310. The plunger 430 is driven by the pressing portion 440. The pressurizing portion 440 transfers the pressure of water flowing through the purified water discharge pipe LE to the plunger 430. [

The water treatment apparatus according to an embodiment of the present invention may include a plurality of chambers for storing at least two kinds of water having different water quality discharged from the filtration unit 200, 310 and 320. The filtration unit 200 includes a reverse osmosis filter 210 for discharging living water having a lower degree of filtration than purified water and purified water used for drinking water, The flow path switching valve 400 interrupts the flow path connecting the filtration unit 200 and the storage unit 300.

 The plurality of chambers (310, 320) includes a purified water chamber (310) for storing purified water discharged from the reverse osmosis filter (210); And a living water chamber 320 for storing living water discharged from the reverse osmosis filter 210. The flow path switching valve 400 interrupts the living water flowing into and out of the living water chamber 320.

 The flow path switching valve 400 is connected to the living water supply pipe LLW, the living water discharge pipe LDS and the purified water discharge pipe LE and is connected to the living water supply pipe LLW and the living water discharge pipe LDS . The flow path switching valve 400 interrupts the life water supply pipe LLW and the purified water supply pipe LPW connecting the storage unit 300 and the filtration unit 200. The flow path switching valve 400 interrupts the flow of life water and purified water. The flow path switching valve 400 is connected to the reverse osmosis filter 210.

FIG. 4 illustrates that the purified water chamber 310 of the water treatment apparatus according to an embodiment of the present invention stores an integer. 5 is a sectional view of the flow path switching valve 400 of FIG.

4 to 5, the partition wall 340 is deformed inside the housing 330 according to a difference between the chambers. In the plurality of chambers 310 and 320, when one of the pressures is increased, the other is decreased in volume. The purified water chamber 310 applies pressure to the living water chamber 320 when the stored water amount increases.

The water treatment apparatus according to an embodiment of the present invention includes a purified water discharge pipe (LE) for guiding the user to supply purified water stored in the purified water chamber 310; And a water intake apparatus 500 for controlling the opening and closing of the purified water discharge pipe LE and the purified water chamber 310 stores the purified water discharged from the reverse osmosis filter 210 when the water intake apparatus 500 is closed, . The pressure of the purified water supply pipe LPW is formed at a certain level or less unless the reservoir 300 is full of purified water. In this case, the shutoff valve 240 is opened and raw water can be introduced into the filtration unit 200 through the raw water pipe LRW.

The raw water flowing into the raw water pipe LRW may flow into the first water filter 220 through the pressure reducing valve VRD and be filtered. The raw water filtered in the first water filter 220 flows into the reverse osmosis filter 210 and the purified water in the reverse osmosis filter 210 flows into the purified water supply pipe LPW, And may be stored in the purification chamber 310. If the constant is continuously stored in the purified water chamber 310 of the storage unit 300, the pressure of the purified water chamber 310 can be increased.

As the purified water storage amount of the purified water chamber 310 increases, the pressure of the purified water chamber 310 increases and the pressure of the purified water supply pipe LPW connected to the purified water chamber 310 also increases. The pressure of the purified water discharge pipe LE branched from the purified water supply pipe LPW and the pressure of the second body portion 420 of the flow path switching valve 400 connected to the purified water discharge pipe LE can also be increased.

When the force applied to the first diaphragm 442 of the pressing portion 440 by the pressure of the second body portion 420 becomes greater than the force applied to the upper side of the plunger 430 by the living water, 430 can be moved to a position where the flow-in pipe (LEI) and the life water discharge pipe (LDS) are connected to each other.

The living water existing in the living water chamber 320 of the storage unit 300 can flow into the living water discharge pipe LDS through the flow-in / out pipe LEI. The living water discharged from the living water chamber 320 can be drained through the drain pipe LD. The constants can be continuously stored in the purified water chamber 310 of the storage unit 300.

When the purified water in the reverse osmosis filter 210 is stored in the purified water chamber 310 of the storage unit 300, the living water present in the living water chamber 320 is discharged. Therefore, no reverse pressure acts on the reverse osmosis filter 210 because no other pressure acts on the purified water chamber 310 except the purified water. In addition, the flow rate of the purified water filtered by the reverse osmosis filter 210 is not reduced, and the filtration efficiency is not lowered.

The living water that has not been filtered by the reverse osmosis filter 210 flows through the living water supply pipe LLW to flow only to the first port 411 of the flow path switching valve 400 or to be drained through the drain pipe LD .

Since the partition wall 340 is formed of a deformable material, the partition wall 340 increases together with an increase in the storage amount of the chamber. However, it is affected by the storage capacity of other chambers. For example, when the size of the purified water chamber 310 is increased, the partition wall 340 is deformed so that the size of the living water chamber 320 becomes smaller. The partition wall 340 deforms according to the pressure between the chambers. For example, when the purified water in the purified water chamber 310 rises, the pressure in the purified water chamber 310 increases. Since the partition wall 340 is a deformable material, the size of the living water chamber 320 is reduced. The living water chamber 320 discharges the living water accommodated therein and its volume decreases.

The water treatment apparatus according to an embodiment of the present invention includes a living water supply pipe LLW for guiding the living water discharged from the reverse osmosis filter 210 to the living water chamber 320; And a living water discharge pipe (LDS) for discharging the living water stored in the living water chamber 320 to the outside. When the flow path switching valve 400 reduces the pressure of the purified water chamber 310, LLW) and the life water discharge pipe (LDS) is closed. The first intermittent portion closes the first port 411 when the second port 412 and the third port 413 communicate with each other.

The water treatment apparatus includes a purified water discharge pipe (LE) for guiding the user to supply purified water contained in the purified water chamber (310); And a water intake device 500 for controlling the opening and closing of the purified water discharge pipe LE and the flow path switching valve 400 opens the living water supply pipe LLW when the water intake device 500 is opened. It is preferred that the living water chamber 320 be emptied to store the integer. Therefore, the flow path switching valve 400 opens the second port 412 and the third port 413 to open the living water discharge pipe LDS. When the pressure in the purified water chamber 310 is reduced, the pressure applied to the pressing portion 440 is reduced. The second port 412 and the third port 413 are opened because the plunger 430 is lowered due to the water pressure of the living water in the first port 411.

FIG. 6 is a view showing that the purified water chamber 310 of the water treatment apparatus according to an embodiment of the present invention discharges purified water. 7 is a cross-sectional view of the flow path switching valve 400 of FIG.

6 to 7, a water treatment apparatus according to an embodiment of the present invention includes a purified water discharge pipe LE for guiding the user to supply purified water stored in the purified water chamber 310; And a water intake apparatus 500 for controlling the opening and closing of the purified water discharge pipe LE. The water purification chamber 310 reduces the pressure when the water intake apparatus 500 is opened. When the amount of water stored in the living water chamber 320 increases, the living water chamber 320 applies pressure to the purified water chamber 310. The water treatment apparatus includes a purified water discharge pipe (LE) for guiding the user to supply purified water contained in the purified water chamber (310); And a water intake device 500 for controlling the opening and closing of the purified water discharge pipe LE and the flow path switching valve 400 opens the living water supply pipe LLW when the water intake device 500 is opened. The partition wall 340 transfers the pressure of the living water chamber 320 increased due to the living water supplied through the living water supply pipe LLW to the purification chamber 310. The living water stored in the living water chamber 320 can flow through the inlet / outlet pipe (LEI) and the drain branch line. The living water flowing through the living water discharge pipe (LDS) can flow into the drain pipe (LD) and can be drained to the outside through the drain pipe (LD). In this case, since the water intake apparatus 500 is closed, the purified water in the reverse osmosis filter 210 flows through the purified water supply pipe LPW and can be stored in the purified water chamber 310 of the storage unit 300.

The living water that has not been filtered by the reverse osmosis filter 210 can flow into the living water chamber 320 of the storage unit 300 by flowing through the living water line and the inlet and outlet pipe LEI. The purified water stored in the purified water chamber 310 can flow to the water intake apparatus 500 through the purified water supply pipe LPW and the purified water discharge pipe LE because the water intake apparatus 500 is open. The purified water can be discharged to the outside through the water intake apparatus 500 and supplied to the user.

The purified water stored in the purified water chamber 310 flows through the purified water supply pipe LPW and flows into the purified water discharge pipe (LE) 310. When the water intake device 500 is opened in the purified water chamber 310 of the storage unit 300, The second water filter 230 is installed in the second water filter 230 and may be filtered. The purified water in the second water filter 230 flows to the water intake apparatus 500 through the purified water discharge pipe LE, the second body portion 420 of the flow path switching valve 400 and the outflow pipe LCE . The purified water can be discharged to the outside through the water intake apparatus 500 and supplied to the user.

When the pressure of the purified water supply pipe LPW becomes lower than the predetermined pressure due to the discharge of the purified water through the water intake apparatus 500, the shutoff valve 240 can be opened. And the raw water may be introduced into the first water filter 220 through the raw water pipe LRW.

The raw water filtered in the first water filter 220 may be introduced into the reverse osmosis filter 210. The purified water in the reverse osmotic pressure filter 210 of the raw water flowing into the reverse osmosis filter 210 flows into the purified water supply pipe LPW and may enter the second water filter 230.

The living water that has not been filtered by the reverse osmosis filter 210 can flow through the living water line) or the drain pipe (LD). In this case, the living water not filtered by the reverse osmosis filter 210 can flush the reverse osmosis filter 210, thereby extending the lifetime of the reverse osmosis filter 210.

The living water can flow to the first port 411 of the channel switching valve 400 through the life water supply pipe LLW. The water to be generated can apply a force to one side of the plunger 430, that is, the upper side of the plunger 430 as shown. The force applied to the upper side of the plunger 430 by the living water is applied to the first diaphragm 442 of the pressing portion 440 by the flow of water flowing through the second body portion 420 of the flow path switching valve 400 The plunger 430 can be moved to a position where the flow-in pipe (LEI) and the life water supply pipe LLW are connected, that is, lowered.

The living water flowing through the living water supply pipe LLW flows into the inflow / outflow pipe, flows into the inflow / outflow line, and can flow into the living water chamber 320 of the storage unit 300. Accordingly, the constant stored in the purified water chamber 310 of the storage unit 300 can be continuously discharged.

When the second intermittent portion closes the third port 413, the first intermittent portion opens the first port 411. The second port 412 and the third port 413 can be opened when the second intermittent portion closes the third port 413. The first port 411 communicates with the second port 412, and the life water supply pipe LLW is opened. In the living water chamber 320, the living water flows in and the pressure increases. The partition wall 340 transfers the pressure of the living water chamber 320 to the purification chamber 310. The water pressure increases due to the contraction of the purified water chamber 310.

FIG. 8 illustrates a case where the purified water chamber 310 of the water treatment apparatus according to the embodiment of the present invention is filled with an integer. 9 is a sectional view of the flow path switching valve 400 of FIG.

8 to 9, the living water chamber 320 can have a volume of 0 when the purified water chamber 310 is filled with an integer or when the size of the purified water chamber 310 is maximally increased. The storage unit 300 stops the discharge of living water when the purified water chamber 310 is filled with an integer or when the size of the purified water chamber 310 is maximally increased. The size of the water purification chamber 310 can not exceed the size of the housing 330. Therefore, when the size of the purified water chamber 310 is maximized, the volume of the living water chamber 320 becomes zero. When the size of the living water chamber 320 becomes zero, living water can not be discharged because there is no living water in the living water chamber 320. Therefore, even if the passage switching valve 400 opens the life water discharge pipe (LDS), the living water does not flow.

The water treatment apparatus according to an embodiment of the present invention includes a shutoff valve 240 for suppressing the flow of purified water flowing into the reverse osmosis filter 210 when the pressure of the purified water chamber 310 is higher than a predetermined generation stopping pressure. When the purified water is filled in the purified water chamber 310 of the storage unit 300, the pressure of the purified water supply pipe LPW may be higher than a predetermined pressure. In this case, the shutoff valve 240 is closed and the raw water may not flow through the raw water pipe LRW. Even if water present in the reverse osmotic pressure filter 210 is discharged through the drain pipe LD, the pressure of the purified water supply pipe LPW can be maintained at a predetermined pressure by the first check valve CV1. The purified water supply pipe LPW can maintain a predetermined pressure so that the shutoff valve 240 can be kept closed without being opened.

The shutoff valve 240 may block or prevent the inflow of raw water into the filtration unit 200 according to the pressure of the purified water supply pipe LPW. The shutoff valve 240 may be connected to a raw water pipe LRW or a filter connection pipe LC. The shutoff valve 240 may be connected to a purified water supply pipe LPW. When the purified water is introduced into the purified water chamber 310 so that the purified water is stored in the purified water chamber 310 or the purified water is discharged from the purified water chamber 310, the pressure of the purified water supply pipe LPW is reduced to a predetermined pressure, LC, the shutoff valve 240 can be opened.

When the purified water chamber 310 is filled with the purified water, the pressure of the purified water supply pipe LPW reaches a predetermined pressure, for example, 60% of the raw water pressure, so that the shutoff valve 240 can be closed. Therefore, the raw water may not flow into the filtration unit 200.

The configuration of the shutoff valve 240 is not particularly limited and any well-known configuration may be employed as long as it is capable of inflow of raw water into the filtration unit 200 or shutoff of inflow according to the pressure of the purified water supply pipe LPW. The purified water supply pipe LPW between the shutoff valve 240 and the reverse osmosis filter 210 may be provided with a first check valve CV1 as shown in FIG. Even if the water present in the reverse osmotic pressure filter 210 is discharged through the drain pipe LD when the purified water is filled in the purified water chamber 310, the water present in the purified water supply pipe LPW is returned to the reverse osmosis filter 210 < / RTI > Therefore, the pressure of the purified water supply pipe LPW can be maintained at a predetermined pressure, and the shutoff valve 240 can be kept closed without being opened.

The water treatment apparatus according to an embodiment of the present invention includes a purified water supply pipe (LPW) for leading purified water discharged from the reverse osmosis filter 210 to the purified water chamber 310, and the shutoff valve 240 is connected to the purified water supply pipe LPW to sense the pressure of the purified water chamber 310. [ The water treatment apparatus according to an embodiment of the present invention includes a raw water pipe LRW for drawing water to the reverse osmosis filter 210 and a shutoff valve 240 for supplying water to the purified water supply pipe LPW or the raw water pipe LRW I will crack down. When the pressure of the purified water chamber 310 increases, the flow-line switching valve 400 opens the life water discharge pipe LDS and closes the life water supply pipe LLW.

And the other side of the connecting passage 421 may be closed by the closing member 422.
