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 increases water pressure of cold water and hot water discharged from a water purifier.

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 lower than the low water level of the water tank, the water stored in the water tank is discharged to the outside There is a problem that it 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 is reduced and the filtration efficiency of the reverse osmosis filter is lowered. In addition, in the case of a direct water type water purifier, the water pressure of the purified water is basically low, so that there is a problem that additional water pressure is required in generating cold and hot water.

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

First, increase the water pressure of the purified water.

Second, increase the water pressure of cold water or hot water.

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; A storage unit for storing at least two kinds of water having different water quality discharged from the filtration unit and forming a plurality of chambers in which the volume of the other one of the chambers decreases when the volume of one of them is increased; A flow path switching valve for interrupting the water flowing in and out of the other chamber by the pressure of water accommodated in one of the chambers; A heat exchange module for exchanging heat with the water discharged from the storage part; And a pressure transfer pipe for transferring the pressure of water from the reservoir to the heat exchange module to the flow path switching valve.

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

The present invention has the following effects.

First, the water pressure of the purified water to be discharged can be increased.

Second, the water pressure of cold water or hot water can be increased.

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. The chamber increases in volume as the water is introduced, and as the volume of the adjacent chamber increases, the other chamber discharges water for volume reduction.

The chambers may be connected to each other in a pressure-transmissible manner. 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 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 flows 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 inhibiting 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 purified water in the purified water chamber 310 is filled with water and water present in the reverse osmotic pressure filter 210 is discharged through the drain pipe LD, 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 is disposed in the piping (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.

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.

[ The branched connection pipe LSC branched from the purified water discharge pipe LE may be connected to one side of the connection passage 421 formed in the second body portion 420 of the flow path switching valve 400. And the other side of the connecting passage 421 may be closed by the closing member 422. [ The pressure of the purified water discharge pipe LE is transmitted to the second body portion 420 of the flow path switching valve 400 so that the flow path switching valve 400 can be operated.

12 to 13, in another embodiment of the present invention, the purified water discharge pipe LE may be directly connected to the water intake apparatus 500.

The branched connection pipe LSC branched from the purified water discharge pipe LE may be connected to the second body portion 420, for example, the center portion of the second body portion 420. [ The pressure of the purified water discharge pipe LE is transmitted to the second body portion 420 of the flow path switching valve 400 so that the flow path switching valve 400 can be operated.

As described above, when the water treatment apparatus according to the present invention is used, the purified water is filtered by the reverse osmosis filter 210 into the purified water chamber 310 provided in the living water chamber 320 by the single flow path switching valve 400, The living water that has not been filtered by the reverse osmotic pressure filter 210 may be introduced into the living water chamber 320 and the purified water stored in the purified water chamber 310 may be discharged. Further, even if the reverse osmosis filter 210 is used, the water can be easily discharged to the outside, and the position of the water intake apparatus 500 from which the purified water is discharged may not be limited. In addition, it is possible to prevent the back pressure from acting on the reverse osmosis filter 210, and the filtration efficiency can be prevented from decreasing without decreasing the flow rate of the purified water that is filtered and discharged from the reverse osmosis filter 210.

FIG. 14 shows a case where an air pump 703 is mounted on a water treatment apparatus according to an embodiment of the present invention. FIG. 15 shows the flow of compressed air in the flow path switching valve 400 in FIG. Fig. 16 shows the bladder 705. Fig.

14 to 16, a water treatment apparatus according to an embodiment of the present invention includes a filtration unit 200 for filtering raw water; A chamber supply pipe (CSP) through which water discharged from the filtration unit (200) flows; And a reservoir 300 detachably connected to the chamber supply line CSP and configured to form a plurality of chambers 310 and 320 that decrease in volume when one of the volumes increases.

The chamber supply piping (CSP) is connected to the storage part (300). The chamber connecting piping (CCP) is connected to the filtration unit 200. The chamber supply piping (CSP) can flow the water discharged from the reservoir (300). The chamber supply line CSP is detachably connected to the storage unit 300, so that the storage unit 300 is replaceable.

The chamber supply piping (CSP) may be formed with a gas injection port 701 through which gas can be injected. A gas injection port 701 is formed in the chamber supply line CSP. The gas injection port 701 is connectable to an external member to supply gas to the chamber supply line CSP. The gas injection port 701 communicates with at least one of the plurality of chambers 310 and 320 by a chamber supply pipeline CSP.

 The gas injection port 701 can be connected to an air pump 703 that sucks air to discharge high-pressure air. The air pump 703 injects high-pressure air into the gas-injecting bore. High pressure air is supplied to any one of the plurality of chambers 310, 320. One of the chambers expands by the high-pressure compressed air. The air pump 703 may be powered or manual. The air pump 703 can be detachably connected to the gas injection port 701.

 The filtration unit 200 includes a reverse osmosis filter 210 that discharges living water having a lower degree of filtration than purified water and purified water used as drinking water. The plurality of chambers 310 and 320 includes a reverse osmosis filter 210, (310) for storing the purified water discharged from the purification chamber (310); And a living water chamber 320 for storing living water discharged from the reverse osmosis filter 210. The chamber supply piping CSP communicates with the living water chamber 320 and the purified water chamber 310. [ The chamber supply piping (CSP) is connected to the living water chamber (320). The chamber supply piping (CSP) includes a purified water supply pipe (LPW), a life water supply pipe (LLW), a life water discharge pipe (LDS), an inlet pipe (LEI) and a drain pipe (LD).

The storage unit 300 includes a housing 330 forming an outer shape and connected to the chamber supply pipe CSP; And a partition 340 disposed inside the housing 330 to partition the plurality of chambers 310 and 320. The purified water chamber 310 is formed inside the living water chamber 320. The housing 330 is detachably connected to the chamber supply line CSP. Thus, the housing 330 can be replaced. Alternatively, the housing 330 may be cleaned and reinstalled. Or the partition 340 disposed inside the housing 330 can be exchanged or cleaned.

The water treatment apparatus according to an embodiment of the present invention includes a bladder 705 which is deformable according to the amount of water and forms the partition 340. The bladder 705 is sterilized or antimicrobially treated and is disposed interchangeably within the housing 330.

The bladder (705) forms a partition (340). The bladder 705 may be a water bag. The bladder 705 is disposed within the housing 330. The bladder 705 is formed of a deformable material. The user can replace the bladder 705 disposed therein after detaching the housing 330. [ Or the bladder 705 may be washed and repacked. The bladder 705 is sterilized or antimicrobially treated so that the generation of bacteria in the purified water can be suppressed. Also, after a predetermined period of time for inhibiting the generation of bacteria, the user can replace the bladder 705. The bladder 705 forms a purified water chamber 310 therein, so that the purified water chamber 310 can be kept clean by replacing the bladder 705. [

 In the water treatment apparatus according to an embodiment of the present invention, the storage unit 300 stops discharging living water when the purified water chamber 310 is filled with purified water. When the purified water chamber 310 is filled, the bladder 705 expands to fill the interior of the housing 330, and the volume of the living water chamber 320 becomes zero. Therefore, there is no more life inside the living water chamber 320. Therefore, the living water chamber 320 can not discharge living water.

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; A living water discharge pipe (LDS) for discharging living water stored in the living water chamber (320) to the outside; And a flow path switching valve (400) for opening the living water supply pipe (LLW) and closing the life water discharge pipe (LDS) when the pressure of the water purification chamber (310) It communicates with the life water discharge pipe (LDS).

The air pump 703 flows the gas injection port 701 to the drain pipe LD. The drain piping (LD) is connected to the domestic water discharge piping (LDS), so that compressed air (compressed gas) flows to the domestic water discharge piping (LDS). Since the living water discharge pipe (LDS) communicates with the living water chamber (320), the compressed air flows into the living water chamber (320).

The water treatment apparatus according to an embodiment of the present invention includes a drain pipe (LD) connected to the reverse osmosis filter 210 and leading living water to the outside, and the drain pipe (LD) LDS), and a gas injection port 701 is formed.

The drain pipe (LD) discharges the living water generated by the reverse osmosis filter (210). The number of lives can be concentrated enriched with minerals than purified water. The drain pipe (LD) is connected to the life water discharge pipe (LDS). The living water discharge pipe (LDS) is connected to the oil passage switching valve (400), and the oil passage valve is connected to the inlet / outlet pipe (LEI).

The water treatment apparatus according to an embodiment of the present invention includes: a filtration unit 200 for filtering raw water; A storage unit 300 storing the purified water discharged from the filtration unit 200 and having a partition 340 movable therein; And an air pump 703 for injecting compressed air into the storage unit 300 to discharge the purified water stored in the storage unit 300 so that the partition wall 340 and the partition wall 340 move.

The replacement timing of the bladder 705 can be automatically displayed on the outside or can be recognized by the user. Or the service person may periodically replace the bladder 705. [ For example, if the user recognizes the replacement time of the bladder 705, it locks the raw water valve and blocks production of purified water and living water. Thereafter, the air pump 703 is connected to the gas injection port 701, and the air pump 703 is operated. When the purified water chamber 310 is full of water, the living water chamber 320 can not discharge living water.

However, the flow path switching valve 400 makes the flow-in / out pipe LEI communicate with the life water discharge pipe LDS. Therefore, the compressed air flowing into the drain pipe LD flows from the life water discharge pipe (LDS) to the flow-in pipe (LEI) via the flow path switching valve 400. [ The compressed air that has flowed into the inlet / outlet pipe (LEI) flows into the living water chamber (320).

Compressed air applies compressive force to the partition wall 340, that is, the outer wall of the bladder 705, to such an extent that the purified water chamber 310 can be contracted. Accordingly, the bladder 705 contracts and the purified water stored in the bladder 705 is discharged. When the supply time of the compressed air becomes sufficiently long, the bladder 705 shrinks until the purified water is completely discharged. At this time, there is no integer or life in the storage unit 300.

If no more water is discharged from the water intake apparatus 500, the user recognizes that all the water has been discharged to the storage unit 300 and separates the storage unit 300 from the chamber supply pipe CSP. Then, the bladder 705 accommodated in the storage unit 300 is replaced. Therefore, even if the storage unit 300 is separated from the piping, the purified water is not discharged from the storage unit 300, so that the user can replace the user himself.

17 shows a case where the heat exchange module 600 is installed in the water treatment apparatus according to an embodiment of the present invention.

Referring to FIG. 17, a water treatment apparatus according to an embodiment of the present invention includes a filtration unit 200 for filtering raw water; A plurality of chambers 310 and 320 for storing at least two types of water having different water qualities discharged from the filtration unit 200 and for decreasing the volume of one of the chambers 310 and 320, ); And a heat exchange module 600 for exchanging heat with the water discharged from the storage part 300.

The heat exchange module 600 exchanges heat with the water discharged from the storage part 300. The heat exchange module (600) absorbs heat or generates heat to change the temperature of the water discharged from the storage part (300). The water discharged from the storage unit 300 includes an integer. The heat exchange module (600) includes a cooling unit (610) for exchanging heat with the purified water discharged from the storage part (300) to discharge cold water.

The cooling unit 610 absorbs the heat energy from the purified water to discharge the cold water. The cooling unit 610 may include a refrigerant that absorbs heat from the purified water and vaporizes and discharges and liquefies the absorbed heat. The cooling unit 610 stores ice, exchanges heat between the purified water and ice, and simultaneously performs inflow of purified water and discharge of cold water.

The cooling unit 610 may include an ice axis system that uses electric energy to freeze ice and to discharge cold water using ice cold. The heat exchange module 600 includes a heating unit 630 for discharging hot water by heat exchange with purified water discharged from the storage unit 300.

 The heating unit 630 includes instantaneous heating means to simultaneously perform inflow of purified water and discharge of hot water.

The heating unit 630 can instantaneously heat the water to be supplied to a high temperature. The heating unit 630 may include a sieve heater or a Ruthenox heater. The heating unit 630 may be a Ruthenox heater. The Ruthenox heater may have a plurality of heating plates to have a plurality of heating parts. Here, the heating plate included in the Ruthenox heater is configured to instantaneously heat the supplied water, and the heating operation can be performed independently of the other heating plates.

As an example, when the heating unit 630 is constituted by a ruthenox heater, the ruthenox heater may be composed of two heating plates, one of which may have a heating plate of 1400 W and the other heating plate of which may be 1000 W have. here,

The 1400 W heating plate and the 1000 W heating plate can be operated independently. Thus, the heating unit 630 can adjust the degree of heating of the supplied water. The heating unit 630 includes a flow control valve 631 for regulating the flow rate of water supplied; A flow rate sensor 633 for measuring the flow rate of water supplied; And an outflow temperature sensor 635 for measuring the temperature of the hot water generated and discharged by the heating unit 630.

The flow rate regulating valve 631 is provided on the flow path of the preceding stage of the instantaneous heating means, so that the flow rate supplied to the instantaneous heating means can be adjusted. The outflow temperature sensor 635 is provided on the flow path at the rear end of the instantaneous heating means, and can measure the temperature of the hot water generated and discharged by the instantaneous heating means.

In this case, the water treatment apparatus according to an embodiment of the present invention may include a control unit (not shown) for controlling the operation of the components, and the control unit may control the flow rate of the water based on the temperature of the hot water measured by the outflow temperature sensor 635 The control valve 631 can be controlled.

The flow rate of the supplied water and the temperature of the generated hot water may be generally in inverse proportion. Under such operating characteristics, the control unit controls the flow rate control valve 631 so that the flow rate of the purified water supplied to the instantaneous heating means increases when the temperature of the hot water measured by the outflow temperature sensor 635 is higher than a preset reference temperature can do. That is, when the temperature of the hot water measured by the outflow temperature sensor 635 is higher than the reference temperature (for example, 100 degrees Celsius), the control unit increases the flow rate of the water supplied to the instantaneous heating means, It is possible to increase the flow velocity of the passing water so as to reduce the heating time of the heated water to generate hot water of a relatively low temperature. As a result, the temperature of the hot water provided to the user becomes higher than the reference temperature, and a safety accident that may occur due to the discharge of a large amount of steam to the extracting unit can be prevented.

When the temperature of the hot water measured by the outflow temperature sensor 635 is lower than a preset reference temperature, the control unit can control the flow rate control valve 631 so that the flow rate of the purified water supplied to the instantaneous heating means decreases. That is, when the temperature of the hot water measured by the outflow temperature sensor 635 is lower than the reference temperature (for example, 85 degrees Celsius or lower), the control unit decreases the flow rate of the water supplied to the instantaneous heating means, It is possible to increase the heating time of the heated water by reducing the flow rate of the passing water so as to generate hot water of a high temperature. This allows the user to provide hot water of a desired temperature.

The cold water shutoff valve 650 interrupts the flow of the cold water discharged from the cooling unit 610. The water purification valve 660 interrupts the flow of purified water at normal temperature. The purified water flowing into the heat exchange module 600 serves as a power source of the water pressure of living water flowing into the living water chamber 320.

 The heat exchange module 600 may be supplied with purified water by communicating with the purified water discharge pipe LE. The purified water chamber 310 is connected to the purified water discharge pipe LE. The purified water discharge pipe LE is connected to the flow path switching valve 400. The purified water discharged from the flow path switching valve 400 flows to the heat exchange module 600. The purified water discharged from the flow path switching valve 400 flows to the heat exchange module 600 for instant cooling or instantaneous heating. The operation of the flow path switching valve 400 when the purified water is supplied to the heat exchange module 600 is the same as that shown in FIG. 7, so a detailed description will be omitted.

The water treatment apparatus according to an embodiment of the present invention includes a filtration unit 200 for discharging at least two kinds of water having different water quality; A water purification chamber (310) storing an integer having a high filtration degree in the water discharged from the filtration unit (200); A living water chamber 320 for storing living water having a filtration degree lower than that of water discharged from the filtration unit 200; A heat exchange module 600 for heat exchange with purified water discharged from the purification chamber 310; And a partition wall 340 for transferring the water pressure of the living water chamber 320 to the purified water chamber 310.

The living water flows into the living water chamber 320 to expand living water, and the purified water chamber 310 shrinks. Accordingly, the purified water contained in the purified water chamber 310 is discharged through the purified water discharge pipe LE. The purified water flowing in the purified water discharge pipe (LE) flows to the heat exchange module (600). The shape of the flow path or the cross-sectional area of the flow path may be deformed, and the change of the flow path generates an integral flow resistance. However, since the water pressure of the living water acts as the power of the purified water, the purified water can flow regardless of the flow resistance of the heat exchange module 600. Therefore, even a direct water-purifying machine without a separate water storage tank can maintain a sufficient water pressure, and hot water and cold water can be smoothly supplied to the user.

17, 5, and 7, the water treatment apparatus according to an embodiment of the present invention includes a water delivery valve (not shown) for transferring the pressure of water from the storage unit 300 to the heat exchange module 600, Piping (PDL).

The pressure delivery pipe (PDL) communicates with the flow path switching valve. The pressure transfer piping (PDL) conveys the pressure of water that is blocked by the flow toward the heat exchange module 600 or the flow toward the heat exchange module 600.

The heat exchange module 600 can act as a flow resistance of the purified water. When hot water or cold water is discharged from the heat exchange module 600, cold water or hot water is discharged to the outside, so a low pressure is applied to the pressure transfer pipe (PDL). In this case, the pressurized portion descends as shown in Fig. 7, so that the flow of domestic water is not disturbed.

The water treatment apparatus according to one embodiment of the present invention includes a purified water discharge pipe (LE) through which purified water discharged from the storage unit (300) flows; And an outflow collecting pipe (OGL) which receives purified water from the purified water discharge pipe (LE) and branches to a plurality of pipes and communicates with the pressure transfer pipe (PDL).

 The outgoing collection pipe (OGL) includes a heat exchange pipe (HCL) in which the heat exchange module (600) is disposed; And a normal-temperature water pipe (RL) in which water at room temperature flows and communicates with the pressure transmission pipe (PDL).

The purified water discharge pipe LE is connected to the storage unit 300. The storage unit 300 forms a space for storing constants. The outgoing collection pipe (OGL) includes a plurality of pipes. A plurality of pipes each have water of different temperature. The plurality of pipes include a heat exchange pipe (HCL) through which cold water and hot water flow, and a cold water pipe (RL) through which a purified water flows at room temperature.

The pressure transfer piping (PDL) is connected to the hot water piping (RL) to transfer the hydraulic pressure of the hot water to the flow path switching valve. Inside the pressure delivery pipe (PDL), the water pressure of the outgoing collection pipe (OGL) is converted to air pressure and the air to be delivered to the flow path switching valve is charged.

The inside of the pressure transfer pipe (PDL) is filled with air. The air transfers the water pressure of the outgoing collection pipe (OGL) to the pressurization part (440). For example, when water is not discharged from the water intake apparatus 500, the outflow pipe (OGL) is pressurized. The raised pressure is transferred to the pressurizing portion 440 through the pressure transfer pipe (PDL). The pressurizing portion 440 rises to produce a flow of domestic water as shown in Fig.

The port connection pipe (PCL) is branched from the purified water discharge pipe (LE) and communicates with the flow path switching valve. The port connection pipe (PCL) is detachably connected to the purified water discharge pipe (LE). The port connection piping (PCL) includes a pressure isolation valve (PV) for interrupting the water supplied from the purified water discharge pipe (LE). The second body portion 420 is connected to the pressure transmission pipe (PDL). The second body portion 420 includes a fifth port 425 and a fourth port 424 that communicate with the pressure transfer pipe (PDL).

When the pressure shutoff valve (PV) for interrupting the port connection pipe (PCL) is opened, the purified water flowing through the purified water discharge pipe (LE) flows through the fourth port (424) and the fifth port (425). In the absence of the heat exchange module 600, the purified water is flowed through the port connection pipe (PCL) to simplify the structure. In this case, only the purified water at room temperature can be discharged. The closing of the fourth port 424 may be effected by a pressure shutoff valve PV.

When the heat exchange module 600 is required, the pressure shutoff valve PV is driven to close the port connection pipe (PCL). In this case, the purified water flowing through the purified water discharge pipe LE flows directly to the heat exchange module 600 without passing through the flow path switching valve, thereby minimizing the flow resistance. In addition, it is possible to prevent the pressurizing portion 440 from operating abnormally due to an increase in hydraulic pressure due to an increase in flow resistance. That is, when the water is discharged from the water intake apparatus 500, the pressurization unit 440 must be lowered, but the pressurization unit 440 may be prevented from increasing due to an abnormal hydraulic pressure increase.

 The filtration part 200 is not disposed on the purified water discharge pipe LE. When the filtration part 200 is disposed in the purified water discharge pipe LE, the filtration part 200 can generate a flow resistance. Therefore, normal operation of the pressing portion 440 may be interrupted. However, such a side effect can be reduced by changing the arrangement of the filtration unit 200.

 The pressure transfer pipe (PDL) communicates with the downstream of the heat exchange module (600). Downstream of the heat exchange module 600 includes a flow path through which the water discharged from the heat exchange module 600 flows or a flow path that bypasses the heat exchange module 600 and can not be directed to the heat exchange module 600.
