Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter module for a gravity-type water purification device, and a gravity-type water purification device including the filter module,

The present invention relates to a water purification apparatus, and more particularly, to a gravity water purification apparatus capable of filtering raw water using gravity.

The supply of clean and safe water is essential for human health and survival. However, in Africa and developing countries, the supply of clean water is not enough, and therefore, polluted ponds and pools of water are often used as drinking water.

Drinking contaminated water can cause various infectious diseases caused by microorganisms contained in contaminated water. In other words, it causes illnesses such as abdominal pain, diarrhea, vomiting and the like, and in severe cases, there are life-threatening problems.

Therefore, to prevent this, it is important that the food or water we eat is not contaminated by microorganisms.

If clean water and adequate food are currently being secured in developing countries, the effect of environmental improvement that can be prevented by clean water supply to reduce the overall mortality rate is far greater than the development of medical or therapeutic technology.

However, since a general water purifier is a principle of constantly applying water pressure and passing the filter through the filter, it is necessary to provide a water pump with a constant water pressure. In the absence of such a facility, there is a limit to that general water purifiers can not be used.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In the drawings, parts not relating to the description are omitted for clarifying the present invention, and the same reference numerals will be added to the same or similar components throughout the specification.

In the filter module 100, 100 ', 200, 200' for gravity type water purifying apparatus according to an embodiment of the present invention, raw water is sucked into the filter member 110 through water pressure due to gravity or position energy in a state of being locked in raw water, And to remove the foreign substances to produce filtered water.

13 and 20, the filter modules 100, 100 ', 200, and 200' for the gravity-type water purification device according to the present invention are disposed on the side of the internal space S where the raw water is stored in the gravity- Raw water around the filter member 110 penetrates into the interior of the filtration member 111 through water pressure due to gravity or potential energy, thereby producing filtered water.

1 to 5, the filter module 110, the common receiving member 120, and the weight-providing members 130, 130 ', and 230 are disposed on the filter module 100, 100', 200, .

At this time, the filter modules 100, 100 ', 200, 200' for the gravity-type water purification apparatus according to the present invention may be modularized so that they can be easily disposed on the side of the gravity-type water purification apparatuses 1000,

For example, the filter modules 100, 100 ', 200, 200' may be configured such that a plurality of filter members 110 spaced apart in parallel and spaced apart from each other are fixed to each other via fastening bars 150, The members 130, 130 ', and 230 may be coupled to the fastening bar 150 side. Each of the filter members 110 may be connected to the common receiving member 120 through a connection pipe 141. The common receiving member 120 may be connected to the common receiving member 120 through a connection pipe 142 (For example, the outlet 311 formed in the first housing 310 described later or the filtrate collecting member 420 in Fig. 20) for discharging the filtered water.

Accordingly, the filtered water produced through each of the filter members 110 can be collected through the common receiving member 120 and then moved to another component side for discharging the filtered water.

Specifically, the plurality of filter members 110 may be integrally formed through one fastening bar 150 having a predetermined length in a state of being arranged in parallel with each other. At this time, the respective receiving ports 114 formed in the filter member 110 are connected to the common receiving member 120 in a one-to-one manner, so that filtered water produced through the respective filter members 110 is transferred to the common receiving member 120 ). ≪ / RTI >

Here, the plurality of filter members 110 may be spaced apart from one another so that a predetermined space can be secured between adjacent filter members 111.

Thus, raw water, which is an object to be filtered, may be introduced into the space between adjacent filter elements 111 so as to surround the filter element 111, and the raw water present around the filter element 111 may be gravity or The filtered water can be simultaneously produced through the respective filtration members 111 by moving to the inside of the filtration member 111 through the water pressure due to the potential energy. The detailed structure of the filter member 110 will be described later.

The common receiving member 120 is for integrating the filtered water produced in each filter member 110. That is, the common receiving member 120 is connected to at least one receiving opening 114 formed in each filter member 110, so that filtered water produced individually in each filter member 110 is collected in one space .

In addition, the common receiving member 120 is provided with a high-pressure fluid such as washing water or high-pressure air supplied from the outside in the backwashing operation for removing foreign matter adhered to the filtering member 111 toward each filter member 110 It can also play a role of distributing. Accordingly, even if the plurality of filter members 110 fixed to the fastening bar 150 are not separately separated, the foreign matters adhered to the respective filtering members 111 can be removed, thereby facilitating the cleaning operation.

15, when one receiving opening 114 is formed in each of the filter members 110, the common receiving member 120 has one receiving opening 114 formed in each of the filter members 110, 20, when a plurality of receiving ports 114 are formed in the respective filter members 110, a plurality of receiving ports 114 formed in each of the filter members 110 may be connected to one And may be connected to the common receiving member 120, respectively. However, the present invention is not limited thereto. The common receiving member 120 may be provided in a number corresponding to the total number of the receiving openings 124 formed in the respective filter members 120, One-to-one connection with the receiving port 124 of the receiver.

To this end, the common receiving member 120 may include a plurality of inlet ports 121 connected to the receiving port 114 and an outlet port 122 for discharging the filtered water to the outside.

The inlet 121 may be connected to the receiving port 114 of the filter member 110 and the inlet 121 may be connected to the receiving port 114 one to one. (See Figs. 15 and 20). Accordingly, the filtered water produced by the plurality of filter members 110 may be introduced into the common receiving member 120 and then be integrated into one.

The weight imparting members 130, 130 'and 230 are provided to increase the total weight of the filter modules 100, 100', 200, and 200 'disposed on the inner space side where the raw water, which is an object to be filtered, is stored.

That is, the weight of the filter modules 100, 100 ', 200, 200' for the gravity-type water purification device according to the present invention is increased through the weight-providing members 130, 130 ', 230 so that the filter modules 100, 100' 200, 200 ') can be maintained in a sinking state or a sinking state on the bottom surface side of the inner space filled with the raw water.

In other words, the filter module 100, 100 ', 200, 200' for a gravity-type water treatment plant according to the present invention can keep the raw water completely locked when the amount of raw water stored in the internal space is large, Even if the amount of raw water is small, the amount of the raw water to be brought into contact with the filtration member 111 is maximized, so that the production of the filtered water can be smoothly performed.

For this, the weight-providing members 130, 130 ', and 230 may be formed as a frame structure and disposed on the lower side of the filter member 110, and may be arranged in a mesh network and arranged in parallel with the filter member 110 . The weight imparting members 130, 130 ', and 230 may be fixed to the fastening bar 150 for fastening the plurality of filter members 110, and may be made of stainless steel.

As shown in FIG. 1 and FIG. 2, the weight imparting members 130 and 130 'may include a first plate 131 having a predetermined area, And the pair of second plates 132 may be formed on both end sides of the fastening bar 150 via fastening holes 133. [ Lt; / RTI > However, the shape of the weight imparting member 130, 130 'is not limited thereto, and the pair of second plates 132 may extend from the first plate 131 for engagement with the fastening bar 150 And it may be provided in the form of a bracket.

At this time, as shown in FIG. 3, at least one through hole 134 may be formed through the weight imparting member 130 '. The passage hole 134 allows the raw water to pass through the filter module 100 'in the process of sinking the filter module 100', thereby minimizing the buoyancy of the filter module 100 ' .

As another example, the weight imparting member 230 may be a mesh network having a plurality of through holes as shown in FIG. 4, and may be disposed at the outermost one of a plurality of filter members 110 arranged in parallel to each other The filter member 110 may be disposed to face the one surface of the filter member 110. The weight imparting members 230 may be disposed in a pair so as to face the respective surfaces of the two filter members 110 disposed on the outermost side of the plurality of filter members 110.

In this case, the weight imparting member 230 may increase the overall weight of the filter module 200, and may filter foreign matter contained in the raw water through a plurality of through holes. A relatively large foreign matter is filtered through the weight-providing member 230 and then flows into the filter member 111 of the filter member 110 so that foreign matter adhering to the surface of the filter member 111 By reducing the amount, the service life of the filter element 111 can be increased and the productivity of the filtered water can be increased.

As another example, the filter module 200 'for a gravity-type water purification device according to an embodiment of the present invention may be configured such that the weight-providing members 130 and 230 are installed in any one of the frame structures shown in FIGS. 2 and 3 And the shape of the mesh network shown in FIG. 4 may be applied.

Meanwhile, the filter member 110 applied to the present invention may be a flat plate type including the filter member 111, the support frame, and the connecting members 113 and 113 ', as shown in FIGS. 6 to 11.

The filter member 111 is for filtering foreign matters from the raw water containing foreign matter and may be a known filter member. However, the filter member 111 may be a plate-shaped member in which a nanofiber web 111c is disposed on both surfaces of the first support member 111a. .

In the present invention, the nanofiber web 111c is for filtering foreign substances contained in the raw water during the passage of the raw water. The first support 111a supports the nanofiber web 111c, The filtrate produced by the nanofiber web 111c can act as a movement path for movement.

In this case, the filter member 111 may have a three-layer structure in which the nanofiber web 111c is directly attached to both surfaces of the first support 111a, and the nanofiber web 111c and the first support Layer structure in which a second support body 111b is interposed between the first and second support members 111a and 111a.

The second support 111b may be formed to have a thickness that is relatively thinner than the thickness of the first support 111a so as to reduce the overall thickness of the filtration member 111. The first support 111a ). ≪ / RTI >

Accordingly, the nanofiber web 111c is attached to the first support 111a without being directly attached to the second support 111b, thereby improving adhesion and facilitating adhesion.

For example, the nanofiber web 111c may be attached to the first support 111a via the second support 111b through thermal fusion, ultrasonic fusion, high frequency fusion, or the like.

At this time, the second support 111b may be partially or completely melted and attached to the first support 111a during the attachment process. For this, the nanofiber web 111c may have a melting temperature higher than the process temperature that is performed during the fusing process so that the nanofiber web 111c is not melted by heat, and the second support 111b may have a melting temperature higher than the process temperature And may be provided to have a low melting temperature.

The second support 111b may be completely melted to have a three-layer structure and only a part of the second support 111b may be melted to form the nanofiber web 111c and the second support 111b. Layer structure in which the second support body 111b remains between the first support bodies 111a. However, the structure of the filtration member 111 is not limited thereto, and it should be noted that it is not necessary that the structure is such that at least one support is interposed between the two nanofiber webs 111c.

In addition, the first support 111a and the second support 111b may be porous substrates so that the filtered water produced by the nanofiber web 111c may serve as a movement path. For example, the first support 111a and / or the second support 111b may be any one of commonly known woven, knitted or nonwoven fabrics commonly used, and the nonwoven fabric may be a chemical bonding nonwoven fabric, a thermal bonding nonwoven fabric, A nonwoven fabric such as a nonwoven fabric, a dry nonwoven fabric such as a nonwoven fabric, a nonwoven fabric, a nonwoven fabric, a nonwoven fabric, a nonwoven fabric or a nonwoven fabric, And the results are shown in Fig.

In other words, the first support 111a and / or the second support 111b are not limited in their materials. For example, synthetic fibers selected from the group consisting of polyester, polypropylene, nylon and polyethylene, or cellulose Lt; / RTI > fibers can be used.

However, it is possible to prevent separation between the first support body 111a and / or the second support body 111b and the nanofiber web 111c during the water treatment process by improving the binding force with the nanofiber web 111c, The first support 111a and the second support 111b may be formed of a low-melting-point polymer compound such as a known low-melting-point polyester and a low-melting-point polyethylene capable of being thermally fused to each other to prevent problems such as lowering of water- And a polyolefin low melting point conjugated fiber having a low melting point polyester as a core and a polyethylene terephthalate as a core and a polyester low melting point conjugated fiber and / or a low melting point polyethylene as a core and a polypropylene core as a core . The melting point of the low melting point polymer compound may be 60-180 ° C., and the thickness of the first support 111 a may be 2-200 μm, but is not limited thereto.

The second support 111b may be made of a different material from the first support 111a but may be made of the same material as the first support 111a, It is possible to increase the adhesion force with the first electrode 111a.

The nanofiber web 111c may be formed through nanofibers to filter foreign matters contained in the filtrate. At this time, the nanofibers may include a fiber forming component including polyacrylonitrile (PAN) and polyvinylidene fluoride (PVDF), and an emulsifying agent for improving miscibility of the fiber forming component.

Here, the fiber forming component may include polyacrylonitrile (PAN) and hydrophilic polyvinylidene fluoride (PVDF), both of which have high hydrophilicity.

The PVDF can secure the mechanical strength and chemical resistance of the nanofiber due to the nature of the material. The PAN is hydrophilic, thereby preventing the hydrophobicity of the nanofiber due to the PVDF and improving the hydrophilicity of the nanofiber, An improved water permeability can be exhibited.

Meanwhile, the nanofiber web 111c may include a nanofiber web having a three-dimensional network structure. For example, nanofibers comprising a fiber forming component comprising polyacrylonitrile (PAN) and polyvinylidene fluoride (PVDF) and an emulsifying agent can be laminated perpendicularly to the radiation plane, Due to the solvent which has not been volatilized / evaporated during the fusing process, fusion occurs in the portion of the laminated nanofibers contacting the surfaces of the fibers to form a three-dimensional network structure.

The nanofiber web 111c may be formed as a single layer or may have multiple layers. For example, the nanofiber web 111c may include a first nanofiber web 111d attached to one surface of the first support 111a or the second support 111b as shown in FIG. 12, And a second nanofiber web 111e laminated on one surface of the nanofiber web 111d. At this time, an antimicrobial material such as a silver nano material may be coated on one surface of the first nanofiber web 111d.

As a result, the raw water is sequentially passed through the second nanofiber web 111e and the first nanofiber web 111d so that the foreign matter is filtered and the antibacterial material contained in the first nanofiber web 111d It is possible to produce high-quality filtered water by filtering out harmful substances such as bacteria again.

In addition, a second nanofiber web 111e which does not contain an antimicrobial substance is laminated on one surface of the first nanofiber web 111d and directly contacted with the raw water, so that the surface of the second nanofiber web 111e is allowed to grow May be possible. Thus, the microorganisms remove organic substances adhering to the surface of the second nanofibrous web 111e, thereby preventing fouling caused by organic matter.

In the present embodiment, silver nanomaterials are exemplified as an example of the antimicrobial material, but it is not limited thereto, and if it is possible to attach or coat the nanofiber web 111c, various known materials known as antibacterial materials can be used Leave.

The support frame is disposed at the edge of the filter member 111 and supports the edge of the filter member 111 so that the filter member 111 can maintain a plate-like shape.

The support frame may be a single member that supports or partially supports the edge of the filter member 111, but a plurality of frames 112 and 112 'may be coupled to the edge of the filter member 111 . ≪ / RTI >

For example, the plurality of frames 112 and 112 'may be respectively disposed on the edge side of the filter member 111 so that one end thereof contacts the other end, The end sides of the two adjacent frames 112, 112 (112, 112 ') can be connected to each other through the connecting members 113, 113'. However, the shape of the support frame is not limited thereto, and may be changed into various shapes such as a circle, arc, polygon, and a combination thereof depending on the shape of the filter member 111, It is clear that any form is acceptable.

At this time, the support frame may serve as a flow path for supporting the filtration member 111 and for the filtered water produced by the filtration member 111 to move to the receiving opening 114 side. For this purpose, each of the frames 112 and 112 'constituting the support frame may be provided in a substantially' C 'shape with one side thereof being opened, and a flow path through which the filtered water flowing from the filtration member 111 moves 112c may be formed (see FIG. 8).

Accordingly, the filter member 111 can be supported by the pair of second plates 112b, which face each other by being inserted into the space formed between the pair of second plates 112b. At this time, the edge of the filtration member 111 inserted into the space formed between the pair of second plates 112b may be inserted at a distance from the first plate 112a.

That is, a restricting member 112d for restricting the insertion depth of the filtration member 111 may be formed on the opposing surfaces of the pair of second plates 112b facing each other. The insertion depth of the filtration member 111 is restricted through the restricting member 112d in the process of fastening the edge of the filtration member 111 to the respective frames 112 and 112 ' A flow path 112c through which filtrate water can move may be formed between the edge side of the first plate 112a and the first plate 112a.

In the present invention, the restraint member 112d may be formed on each of the opposing surfaces of the pair of second plates 112b facing each other, but may be formed on only one of the pair of second plates 112b . In addition, the restraint member 112d may be entirely or partially provided along the longitudinal direction of each frame. When the restraint members 112d are formed on the opposing surfaces of the pair of second plates 112b facing each other, the respective restraint members 112d are spaced apart from each other with a predetermined interval, To the flow path 112c side.

Meanwhile, the filter member 110 applied to the present invention may include connecting members 113 and 113 'that are coupled to the edge of the support frame. A plurality of such connecting members 113 and 113 'may be provided, and the ends of the two adjacent frames 112 and 112 (112 and 112') may be fixed to the corner of the supporting frame.

To this end, the connecting members 113 and 113 'may include a body 113a having one side opened so as to insert the end sides of the adjacent frames 112 and 112 (112 and 112'). Accordingly, two frames adjacent to each other among the plurality of frames 112 and 112 'constituting the support frame can be fixed by the body 113a by inserting the end sides into the body 113a.

For example, the end of one of the two frames 112 adjacent to each other is inserted in the first direction of the body 113a, and the end of the other one of the frames 112 ' (See FIG. 10) inserted into the first direction and in contact with the end of the frame 112 inserted in the first direction.

Here, the first direction and the second direction may be directions orthogonal to each other on the same plane, or may be inclined to have a predetermined angle with respect to one straight line on the same plane.

When a plurality of filter members 110 are arranged in parallel to each other with a space therebetween, an interval adjusting unit 115 is provided so that each of the filtering members 111 can be spaced apart from each other . The gap adjusting member 115 may be provided on at least one of the plurality of frames 112 and 112 'constituting the support frame, but may be provided on at least one of the connecting members 113 and 113'.

At this time, the connection member 113 'in which the receiving opening 114 is formed communicates with the flow channels 112c formed in the two frames 112 and 112' when they are coupled with the two neighboring frames 112 and 112 ' And the collecting space 116 may be formed at a position in communication with the receiving opening 114. [

For example, the collection space 116 includes two frames 112 and 112 'inserted into the connection member 113' when the connection member 113 'in which the receiving opening 114 is formed and the two frames 112 and 112' And the collecting space 116 may be formed at one end of one of the two frames 112 and 112 'inserted into the connecting members 113 and 113' .

The filter modules 100, 100 ', 200, 200' for the gravity-type water purification apparatus may be applied to the gravity water purification apparatuses 1000, 2000 in which raw water is introduced into the filter member 110 by gravity and then filtered water is discharged.

That is, the gravity-type water purification apparatus 1000, 2000 according to the present invention includes the housing 310, 410 and the filter module 100 as shown in Figs. 13 to 17 and Fig.

The housing 310 and 410 may be formed as a housing having a predetermined internal space S where raw water as a treatment target solution is stored and a filter module 100 for producing filtered water from the raw water is disposed.

At this time, the internal space S of the housing 310 and 410 may be formed as one space or may be divided into two spaces S1 and S2.

13 to 17, the housing 310 includes a first housing 310a having a first space S1 in which raw water is stored, a second space S2 in which the filtered water is stored, And a second housing 310b formed with the second housing 310b.

A filter module 100 for removing foreign substances contained in the raw water may be disposed in the first space S1. The filter module 100 may be connected to the bottom surface of the first housing 310a, So that only filtered water produced through the filter module 100 is prevented from flowing into the second housing 310b through the outlet 311. In this case, To the second space S2 side. In addition, at least one handle 316 may be formed on one side of the first housing 310a so that the user can easily mount the handle 310 on the first housing 310a.

In addition, the filter module 100 may be in the form of a module in which a plurality of filter members 110 are fixed to each other via fastening bars 150 as described above. The filter module 100 is disposed in the first space S1 and maintains a state of being submerged in the raw water by its own weight so that the raw water around the filter member 110 through gravity or water pressure is supplied to the inside of the filtration member 111 To produce filtered water. Since the filter module 100 is the same as that described above, a detailed description thereof will be omitted.

The filter module 100 may be connected to the outlet 311 formed on the bottom surface of the first housing 310a through the connection pipe 162 in a state where the filter module 100 is disposed in the first space S1 . Accordingly, the filtered water produced through the filter module 100 can be moved to the second space S1 formed in the second housing 310b through the outlet 311. [0050] FIG.

At this time, the first housing 310a may be disposed on the upper side of the second housing 310b. Accordingly, the raw water stored in the first space S1 can be infiltrated into the filtration member 111 by gravity or water pressure when the outlet 311 is opened. Therefore, the raw water can be dropped from the outside of the filter member 121 to the inside of the filter unit 121 through the outlet 311 after the foreign matter is filtered.

As described above, the gravity water filtering apparatus 1000 according to the embodiment of the present invention allows the filter module 100 and the first housing 310a storing the raw water to be positioned on the upper side of the second housing 310b, The raw water can penetrate to the filter member 121 side of the filter module by using the natural power generated through the water pressure caused by the energy. Thus, it is possible to produce filtered water even without using additional power such as electricity, so that it is possible to easily produce filtered water required even in a harsh environment in which a periodical facility such as electricity is not installed, electricity can not be supplied, or is difficult.

Meanwhile, a drain outlet 312 communicating with the first space S1 is formed at one side of the first housing 310a, thereby separating foreign matter deposited on the bottom surface of the first housing 310a from the raw water The raw water stored in the first space S1 may be discharged to the outside if necessary.

At this time, the filtered water outlet 313 may be formed at a position near the bottom surface of the second housing 310b so that filtered water stored in the second space S2 can be smoothly discharged by gravity, 2 The bottom surface of the housing 310b may be formed as an inclined surface having a predetermined inclination so that the filtered water stored in the second space S2 can smoothly move toward the filtered water outlet 313.

Here, a well-known on / off valve 314 is provided on the side of the drain outlet 312 and the filtered water outlet 313 so that the user can easily change the open / close state.

Meanwhile, a lid 320 for opening and closing the open top of the first space S1 may be rotatably connected to the upper side of the first housing 310a. Accordingly, when it is necessary to supply the raw water to the first space S1 or to replace the filter module disposed in the first space S1, the cover 320 is opened to the first space S1 side You can feed raw water or simply replace the filter module.

At this time, the cover 320 may be provided with at least one injection hole 322 formed to pass through the predetermined space so as to supply raw water to the first space S1 side. Accordingly, if it is necessary to supply the raw water to the first space S1, the raw water can be supplied to the first space S1 through the charging hole 322 without opening the lid 320. [

In addition, a screen member 324 surrounding the charging hole 322 may be formed around the charging hole 322 to have a predetermined height from one surface of the charging member 320. Therefore, when raw water is supplied to the first space S1 through the input hole 322, even if the amount of raw water supplied to the input hole 322 is large, 322 are prevented from flowing away and thus the raw water supply operation can be easily performed.

At this time, a drawing wire 346 for filtering foreign matters contained in the raw water may be disposed on the upper side of the charging hole 322. Accordingly, when the raw water contains volumetric foreign material such as leaves or mud, foreign matter having a large volume is filtered by the filter net 346, thereby increasing the filtration efficiency of the filter module. The screen 344 may be detachably coupled to the screen member 324, or may be formed of any known material such as stainless steel or plastic.

Here, the first housing 310a and the second housing 310b may be integrally formed with each other or may be detachably coupled.

That is, the housing 310 is formed integrally with the first housing 310a and the second housing 310b, and a bottom surface of the first housing 310a or an upper surface of the second housing 310b And serves to partition the first space S1 and the second space S2 so that the raw water stored in the first space S1 and the filtered water stored in the second space S2 are separated from each other have.

Alternatively, the first housing 310a and the second housing 310b may be removably formed in the housing 310, and the first housing 310a may be formed on the upper side of the second housing 310b As shown in FIG.

That is, as shown in FIG. 14, a coupling hole 315 for supporting the lower edge side of the first housing 310a is formed on the upper edge side of the second housing 310b, so that the first housing 310a May be coupled to the upper side of the second housing 310b.

For example, the coupling hole 315 may be formed on the upper edge side of the second housing 310b in a substantially 'C' shape. Accordingly, the first housing 310a disposed on the upper side of the second housing 310b can be easily coupled to the second housing 310b by closely contacting the lower edge side with the coupling hole 315, The flow in the left and right directions can be prevented by the first and second flow paths 315 and 315. [ In addition, when the first housing 310a or the second housing 310b is partially replaced, the first housing 310a is lifted up and the lower edge side is detached from the coupling hole 315 Only the housing can be easily replaced.

In the present invention, when the first housing 310a and the second housing 310b are detachably formed, the upper surface of the second housing 310b has a predetermined area in a region corresponding to the outlet 311 The opening 317 can be formed through. Accordingly, the filtered water discharged through the outlet 311 may fall into the second space S2 and be stored in the second space S2.

In this case, the upper plate has a predetermined height and a bushing 318 surrounding the rim of the opening 317, thereby maximizing the amount of filtered water stored in the second space S2.

At this time, the outlet 311 may allow or block the discharge of the filtered water produced by the filter module 100 through the opening and closing means 330.

Here, the opening / closing means 330 is operated automatically by the water level of the filtered water stored in the second space S2 to allow or block the discharge of the filtered water, thereby not requiring a separate driving force such as electricity. .

For example, the opening and closing means 330 may include a hollow tube body 331 to be coupled to the outlet 311, and a link member 332 rotatably connected to the tube body 331, The sealing member 333 and the buoyancy member 334 can be fixed to both end portions of the link member 332 (see Fig. 18).

The sealing member 333 may be rotated together with the link member 332 to open or close the outlet 311 and the buoyancy member 334 may be stored in the second space S2. And can be provided with a driving force for rotating the link member 332 by being lifted and lowered by buoyancy depending on the level of the filtered water.

When the amount of filtered water flowing into the second space S2 is small, the opening / closing means 330 rotates the link member 332 downward by the weight of the buoyancy member 334, 311) can be kept open (see Fig. 19 (a)).

On the contrary, when a certain amount of filtered water is filled in the second space S2, the buoyancy member 334 floats on the surface of the filtered water and rises by buoyancy as the level of the filtered water stored in the second space S2 rises, The link member 332 can be pivoted to the upper side (see Fig. 19 (b)). The sealing member 333 fixed to the end portion of the link member 332 covers the outlet 311 and changes the outlet 311 to the closed state so that the filtered water produced through the filter module flows into the second space (S2).

When the amount of the filtered water that can be accommodated in the second space S2 is filled, the gravity water filtering apparatus 1000 according to the present invention changes the outlet 311 to the closed state through the opening / closing means 330, The production of the filtered water through the filter module can be stopped so that the raw water or the produced filtered water can be prevented from being unnecessarily discarded.
