Description

[0001] WATER PURIFICATION FILTERING DEVICE [0002]

The present invention relates to a water filter device, and more particularly, to a water filter device in which water supplied through an inlet port extends a flow path through a filter part to improve a water purification effect, and water is lost at intervals between the filter part and the case, The filter unit can be prevented from being discharged without passing through the filter unit, and the filter unit can be easily separated and replaced with water.

2. Description of the Related Art Generally, a variety of water supply devices including a shower are devices in which hot water and cold water are mixed and supplied at appropriate ratios to allow a user to use water at a desired temperature. For example, in the case of a shower, If there are fine particles such as various kinds of contaminants or odors such as residual chlorine or organic matter, as well as mainly large particles such as bars, sand, earth, and rust from the shower head, There was a problem of seriously harming health.

In order to solve this problem, a water filter device has been proposed. The water filter device according to the prior art has an external body to form a storage space therein, and an inlet port leading to the storage space is opened in the middle of the body A primary filtration unit detachably inserted into the storage space of the case and configured to primarily filter the water introduced into the storage space through the intake port, A secondary filtration means which is removably inserted coaxially inside the filtration means and is adapted to filter the primary filtered water by the primary filtration means and then discharge the water through the outflow port; And a cap which is detachably coupled to close the receiving space into which the primary and secondary filtering means are inserted.

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Registration No. 10-1009654 (published on Jan. 19, 2011, entitled "Water purification filter device").

The water filter device according to the related art has a water inlet formed at a central portion of the case and a water outlet formed at one end of the case. Therefore, the water flowing in the direction adjacent to the water outlet is relatively short in the passage through the filtering means. It is difficult to sufficiently remove minute substances such as foreign matter or residual chlorine, and to discharge the water through the outflow port to improve the water purification effect.

In addition, since the filtration means of the conventional water filter device is seated on the integrated cap and inserted into the outlet port, the water is discharged at intervals between the filtration means and the integrated cap, and water can be discharged to the outlet port without passing through the filtration means There is a problem that it is difficult to increase the reliability of the water purification operation.

In addition, since the filtration means and the integrated cap are assembled so as to be in close contact with each other, it is difficult to separate and replace the filtration means and the integrated cap having different periods of replacement.

Therefore, there is a need for improvement.

The present invention can prevent the water from being discharged without passing through the filter portion due to the water being lost due to the gap between the filter portion and the case by extending the flow path through which the water supplied through the inlet portion extends. And an object thereof is to provide a water filter device capable of easily separating and replacing the filter part individually.

The present invention relates to a water purifying apparatus, comprising: a case having an inner space formed with an inlet through which water is introduced and an outlet through which water is discharged; A filter unit which is accommodated through the opening and that filters foreign substances or fine substances contained in the water supplied through the inlet; A plug member coupled to the opening to close the storage space; And a bypass section for bypassing water passing through the filter section so as to extend a flow path of water passing through the filter section, wherein the filter section has a hollow hole section for allowing water supplied through the inlet port to permeate into the inside from the outer wall, A hollow filter housed in the case; And a ceramic ball filled in the hollow hole such that foreign substances contained in the water or fine particles such as residual chlorine are filtered while the water having passed through the hollow filter is moved to the discharge port side along the hollow hole portion .

In addition, the bypass portion of the present invention includes a partition pipe inserted into the hollow hole portion to partition the hollow filter and the ceramic ball.

Further, the detour of the present invention may include: a first tread provided at one end of the partition pipe; And a second trough having a plurality of holes each having a diameter smaller than that of the ceramic ball and provided at the other end of the partition pipe.

Further, the present invention further includes a connection portion connecting the partition pipe to the discharge port to prevent water supplied through the inlet port from passing through the hollow filter and the case without passing through the hollow filter .

The connection portion of the present invention may further include: an insertion protrusion inserted into the engagement rib extending from the discharge port; A press-fitting rib integrally connected to the insertion protrusion and press-fitted into the partition pipe; And a seat portion extending from the partition pipe and on which the filter portion is seated.

Further, the present invention is characterized in that the hollow filter is pressed toward the discharge port to prevent the water supplied through the inlet from passing through the gap between the hollow filter and the partition pipe without passing through the hollow filter, And a resilient pressing portion for closely contacting the partition pipe.

The elastic pressing portion of the present invention may further include: an inclined surface provided between the partition pipe and the seating portion; A pressure panel disposed between the plug member and the filter unit so that the edge of the hollow filter opposite to the inclined surface is deformed and pressed and pressing the hollow filter toward the slope; And a projection member provided on the stopper member and pressing the pressure panel toward the hollow filter.

The elastic pressing portion of the present invention may further include: an inclined surface provided between the partition pipe and the seating portion; And a protruding member provided on the stopper member and adapted to press the hollow filter toward the seat portion so that the edge of the hollow filter facing the inclined surface is deformed and closely contacted.

The water filter device according to the present invention bypasses the flow path of the water passing through the hollow filter so that the water is discharged through the discharge port after the water is passed from one end to the other end of the space part in which the ceramic ball is received, So that the foreign matter contained in the water can be more efficiently filtered.

In addition, the water filter device according to the present invention is provided with the elastic pressing portion for pressing the hollow filter toward the inclined surface of the partition pipe, so that when the plug portion is inserted after the filter portion is housed in the case, the hollow filter is brought into close contact with the inclined surface of the partition pipe There is an advantage that the hollow filter can be prevented from being discharged without passing through the hollow filter while passing water at intervals between the partition pipes.

In addition, in the water filter device according to the present invention, when the pressing force for pressing the hollow filter on the inclined surface is released, the hollow filter is unfolded by the elastic force of the hollow filter and is slightly moved away from the partition pipe.

Sectional view showing a state in which the hollow filter is inserted into the outer periphery of the partition pipe.

1 to 9, the water filter apparatus according to an embodiment of the present invention includes an inlet 12 through which water is introduced and an outlet 14 through which water is discharged, (34, 36) for filtering foreign substances contained in water supplied through the opening (16) and supplied through the inlet (12), and an opening portion And a detour 50 for bypassing the water passing through the filter units 34 and 36 so as to extend the flow path of the water passing through the filter units 34 and 36. [

Accordingly, when the water pipe is connected to the water inlet 12 and the water pipe is opened, the water supplied through the water inlet 12 passes through the filter portions 34 and 36, and foreign matter is filtered. The water can be discharged to the outside of the case 10 through a separate discharge pipe to supply purified water to the user.

The water passing through the filter portions 34 and 36 is extended by the bypass portion 50 to pass through the filter portions 34 and 36 so that the water flowing in the vicinity of the discharge port 14 is also separated by the bypass portion 50 So that the foreign matters contained in the water can be sufficiently absorbed while passing through the filter portions 34 and 36. Therefore, in the case of water flowing in the direction adjacent to the outlet port, as in the conventional water filter section, the flow path passing through the filter section is relatively short, so that the fine substances such as foreign substances or residual chlorine contained in the water are not sufficiently filtered, Which is difficult to improve the water purification effect, can be solved by the bypass unit 50 of the present invention.

The filter units 34 and 36 include a hollow filter 34 having a hollow hole portion 34c for allowing water supplied through the inlet 12 to permeate through the outer wall and passing through the inlet hole 12 and stored in the case 10, And a ceramic ball 36 filled in the hollow hole portion 34c so as to filter foreign substances contained in the water while the water having passed through the hollow hole portion 34 is moved toward the discharge port 14 side along the hollow hole portion 34c.

The case 10 of the present embodiment is formed in a cylindrical shape so as to have a storage space therein and has an inlet 12 at the center of the peripheral surface and an opening 16 And an outlet 14 having a smaller diameter than the opening 16 is provided at the other end.

Therefore, water flows in from the peripheral surface of the cylindrical case 10 and water that has passed through the hollow filter 34 stored in the case 10 is moved to the other end of the case 10, that is, (14). ≪ / RTI >

The flow path through the filter portions 34 and 36 can be shortened while the water flowing from the center portion of the peripheral surface of the case 10 moves toward the discharge port 14 disposed at the lower end of the case 10, The water that has passed through the hollow filter 34 is filled in the hollow filter portion 34 and then flows into the hollow hole portion 34c again after passing through the bypass portion 50. Thereafter, To the discharge port 14 side.

The water filled in the filter portions 34 and 36 is filled up to the upper end of the hollow filter 34 and then flows into the hollow hole portion 34c through the bypass portion 50 and then flows into the ceramic ball 36 And then discharged to the outside of the case 10 through the discharge port 14. [

The bypass portion 50 includes a partition pipe 52 inserted into the hollow hole portion 34c so as to partition the hollow filter 34 and the ceramic ball 36, And a second tread 56 having a plurality of holes smaller in diameter than the ceramic ball 36 and provided at the other end of the partition pipe 52. [

The hollow filter 34 is made of a fiber material having a hollow pipe shape smaller than the diameter of the inner wall of the case 10 and has a cylindrical shape with a hollow hole portion 34c and a partition pipe 52 Can be inserted or withdrawn.

Since the first rudder 54 and the second rudder 56 are provided at one end and the other end of the partition pipe 52, a plurality of ceramic balls 36 can be accommodated in the partition pipe 52, The water that has passed through the filter 34 and flows into the partition pipe 52 through the first rudder 54 is moved to the other end of the partition pipe 52 and contacts with the ceramic ball 36, .

A hollow filter 34. The water pipe compartment 52, the lower side (60b) of the pipe just inside the ceramic ball 36 is accommodated by passing through the steps described above, The water discharged into the hollow hole portion 34c flows into the partition pipe 52 through the first trough 54 after the water is filled in the hollow filter 34 up to the upper end of the partition pipe 52, And flows into the lower side 60b of the inside of the pipe through the upper side 60a of the pipe inside.

As described above, the water introduced into the partition pipe 52 is contacted with the ceramic ball 36, while foreign substances contained in the water are filtered while flowing in the downward direction. Depending on the type and function of the ceramic ball 36 to be filled, A material advantageous to the user's body such as far-infrared ray or anion radiated from the ceramic ball 36 can be mixed with water and supplied.

Here, the composition and the composition ratio of the ceramic ball 36 for supplying the far-infrared rays or the anion or the like to water can be easily carried out by those skilled in the art who know the technical composition of the present invention. Therefore, Is omitted.

The present embodiment is different from the first embodiment in that the partition pipe 52 is formed so as to prevent the water supplied through the inlet 12 from passing through the gap between the hollow filter 34 and the case 10 without passing through the hollow filter 34. [ To the discharge port (14).

The partition pipe 52 can be coupled to the discharge port 14 so that the water that permeates and moves by the space between the inner wall of the case 10 and the hollow filter 34 flows between the partition pipe 52 and the discharge port 14 It is possible to prevent loss at an interval of < / RTI >

The connecting portion 70 includes an insertion protrusion 72 inserted into the engagement rib 14a extending from the discharge port 14 and a press-fitting rib 74 integrally connected with the insertion protrusion 72 and press-fitted into the partition pipe 52 And a seating portion 76 extending from the partition pipe 52 and on which the hollow filter 34 is seated.

An insertion protrusion 72 and an insertion protrusion 72 having a relatively small diameter are inserted in the discharge port 14 so as to be inserted into the coupling rib 14a. And a press-fitting rib 74, which is formed integrally with the insert projection 72 and has a larger diameter than the insert projection 72, is press-fitted into the partition pipe is interposed between the partition pipe 52 and the engagement rib 14a.

When the end of the partition pipe 52 is inserted into the discharge port 14 after the press-fitting rib 74 is press-fitted into the partition pipe 52, the insertion protrusion 72 is inserted into the inside of the engagement rib 14a, (14) and the partition pipe (52) are combined.

Therefore, the inner space of the case 10 is partitioned into two spaces by the partition pipe 52, and the water penetrating through the gap between the partition pipe 52 and the outlet 14 is blocked by the rubber o-ring 25 do.

The water supplied to the inside of the case 10 through the inlet port 12 can not be directly transferred to the outlet port 14 by the partition pipe 52 installed as described above, After passing through the hollow filter 34 and flowing into one end of the partition pipe 52 and then passing through the inside of the partition pipe 52 and passing through the discharge port 14 And is discharged to the outside of the case (10).

Therefore, the effect of extending the flow path of the water passing through the filter portions 34, 36 is long, and the flow path of the water passing through the filter portions 34, 36 is extended, effectively filtering the foreign matter contained in the water.

The first rudder 54 is provided at one end of the partition pipe 52 and the second rudder 56 is provided at the other end of the partition pipe 52. A plurality of ceramic balls 36 The water flowing into the partition pipe 52 through the first rudder 54 is moved while passing through the gap between the ceramic balls 36 and is discharged through the second rudder 56 (14).

The first rudder 54 is integrally formed at one end of the partition pipe 52 and the second rudder 56 is installed at the pressurizing rib 74 so as to be disposed at the other end of the partition pipe 52.

The present embodiment is characterized in that the water supplied through the inlet 12 is prevented from passing through the hollow filter 34 to prevent the water from passing through the hollow filter 34 and passing through the gap between the hollow filter 34 and the partition pipe 52 And the hollow filter 34 is brought into close contact with the partition pipe 52. When the pressing force applied to the hollow filter 34 is released, the hollow filter 34 is pressed against the seating part 76 And an elastic pressing portion 80 for moving the pressing portion 80 to the away side.

The gap between the hollow filter 34 and the partition pipe 52 is blocked by the elastic pressing portion 80 and the gap between the hollow filter 34 and the partition pipe 52 does not pass through the hollow filter 34, So that the moving water is prevented from moving to the outside of the partition pipe 52.

The elastic pressing portion 80 is formed in such a manner that the inclined face 82 provided between the partition pipe 52 and the seating portion 76 and the edge 34a of the hollow filter 34 opposed to the inclined face 82 are deformed, A pressure panel 84 disposed between the plug member 30 and the hollow filter 34 so as to press the hollow filter 34 toward the inclined surface 82 and a pressure panel 84 provided on the plug member 30, And a protruding member 86 that presses the hollow filter 34 toward the hollow filter 34 side.

An inclined surface 82 is provided between the circumferential surface of the partition pipe 52 and the seating portion 76. The inclined surface 82 is provided at the other end of the partition pipe 52, The edge 34a formed at the inner end of the hollow filter 34 is pressed against the inclined surface 82 and deformed to block the gap between the hollow filter 34 and the partition pipe 52. [

The seat portion (76) is bent from the peripheral surface of the partition pipe (52) and extends laterally.

A pressing panel 84 is integrally formed at the upper end of the hollow filter 34 with a protruding rib 84a press-fitted into the hollow hole 34c. The upper surface of the pressing panel 84 protrudes toward the plug 30 A protrusion 84b is formed.

The plug member 30 is provided with the protruding member 86 for pressing the pressing panel 84 toward the hollow filter 34 so that the user inserts the hollow filter 34 into the case 10, The protruding member 86 pressurizes the pressure panel 84 to press the hollow filter 34 toward the discharge port 14. [

The inner edge 34a of the hollow filter 34 is deformed while being pressed against the inclined surface 82 to prevent the water from penetrating the gap between the hollow filter 34 and the partition pipe 52, The water introduced from the inlet port 12 flows into the gap between the hollow filter 34 and the partition pipe 52 without passing through the hollow filter 34 and consequently flows into the discharge port 14 without passing through the hollow filter 34. [ It is possible to prevent the water from being discharged to the outside.

The first screw thread 16a formed on the opening 16 and the second screw thread 32 formed on the stopper member 30 are arranged to face each other and the stopper member 30 is rotated to engage with the projecting member 86 Presses the pressure panel 84 toward the discharge port 14 while the inner edge 34a of the hollow filter 34 is pressed against the inclined surface 82 and is deformed and tightly contacted.

Thereafter, when the user replaces the hollow filter 34, the edge 34a of the hollow filter 34, which has been deformed, is unfolded and the inclined surface 82 is deformed when the plug member 30 is separated from the opening 16. [ The hollow filter 34 is disengaged from the seating portion 76 of the partition pipe 52 so that the user can easily pull out only the hollow filter 34 to the outside of the case 10. [

The hollow filter 34 separated from the outer side of the partition pipe 52 can be easily slid without being in close contact with the outer wall of the partition pipe 52, And can be drawn out to the outside.

Since the water that flows into the case 10 passes through the hollow filter 34 firstly, most of the foreign substances contained in the water are filtered by the hollow filter 34 and the water filtered primarily by the foreign substance flows into the partition pipe 52 And comes into contact with the ceramic ball 36 while flowing. Generally, since the hollow filter 34 filters foreign matters in water, the lifetime is shorter than that of the ceramic balls 36, and frequent replacement is required.

Therefore, the user changes the hollow filter 34 about three times or more during a period in which the ceramic ball 36 is replaced once. In this embodiment, by the urging force of the stopper member 30, When the user separates the stopper member 30 from the case 10 when the user removes the edge 34a of the hollow filter 34 due to the restoring force of the hollow filter 34, The hollow filter 34 is separated from the inclined surface 82 so that the hollow filter 34 is away from the seating surface 76 and is easily separated.

When a plurality of spacing ribs 52a are formed on the outer wall of the partition pipe 52 so that the partition pipe 52 extending as an inclined portion is inserted to be inserted into the hollow hole portion 34c of the hollow filter 34, The pipe 52 is installed at the central position of the hollow hole portion 34c of the hollow filter 34 and at the same time the spacing rib 52a is brought into close contact with the inner wall of the hollow hole portion 34c and the outer wall of the partition pipe 52 and the hollow hole portion 34c do not flow but are firmly supported.

In the above-described example, the elastic pressing portion 80 includes the inclined surface 82, the pressing panel 84, and the protruding member 86. However, the elastic pressing portion 80 may be formed on the upper portion of the hollow filter 34, In the absence of the pressure panel 84, the elastic pressing portion 80 may be formed only of the inclined surface 82 and the protruding member 86. In this case, when the user inserts the hollow filter 34 without the pressure panel 84 into the case 10 and then the stopper member 30 is engaged with the opening 16 of the case 10, The hollow filter 34 directly pressurizes the hollow filter 34 to bring the hollow filter 34 into close contact with the seating part 76 so that the hollow filter 34 and the partition pipe 52 are in close contact with each other.

The operation of the water filter apparatus according to an embodiment of the present invention will now be described.

6, the ceramic ball 36 is filled in the partition pipe 52 provided with the first rudder 54 and then the second rudder 56 and the press-fitting rib 74 After being press-fitted into the other end of the partition pipe 52, the partition pipe 52 is inserted into the case 10 as shown in Fig. Next, as shown in Fig. 8, the press-fitting rib 74 fitted in the partition pipe 52 is coupled to the engagement rib 14a of the discharge port 14, and the partition pipe 52 And the opening 16 of the case 10 and the stopper member 30 are engaged with each other.

At this time, as shown in FIG. 2, the projecting member 86 provided on the stopper member 30 presses the pressure panel 84 and the hollow filter 34 toward the seating portion 76, The end edge 34a is pressed against the inclined surface 82 and is brought into close contact. 10, when the pressure panel 84 is not formed on the upper portion of the hollow filter 34, the protruding member 86 directly presses the hollow filter 34 toward the seating portion 76, The inner end edge 34a of the filter 34 is pressed against the inclined surface 82 and is brought into close contact.

The water supplied to the inside of the case 10 through the inlet 12 is discharged to the inside of the case 10 through the inlet 12, And then flows into the partition pipe 52 through the end of the partition pipe 52 after being filled in the space between the outer wall of the partition pipe 52 and the outer wall.

At this time, in this embodiment, the o-ring 25 prevents the water from being leaked at a distance between the seating portion 76 and the discharge port 14, and the inclined surface 82 and the inner edge of the hollow filter 34 It is possible to prevent water from passing through the space between the seating part 76 and the hollow filter 34 by the filter 34a and improve the filtering effect of the filter parts 34 and 36. [

When the operator releases the cap member 30 from the case 10 due to the time for replacing the hollow filter 34, the edge 34a of the hollow filter 34, which has been deformed by the inclined surface 82, The end of the hollow filter 34 moves away from the seating part 76 and is pushed out of the case 10 so that the user can easily remove the hollow filter 34 from the partition pipe 52 And can be taken out to the outside of the case 10 separately.

At this time, the hollow filter 34 pushed outwardly of the case 10 prevents the inner wall of the hollow filter 34 and the outer wall of the partition pipe 52 from being in close contact with each other by the partition pipe 52 extending as an inclined portion. So that the hollow filter 34 can be easily separated from the case 10 and discharged.

As a result, the water supplied through the inlet port extends the flow path through the filter section to improve the water purification effect, and water can be prevented from being discharged at a distance between the filter section and the case without water passing through the filter section, It is possible to provide a water filter apparatus which can easily separate filter units and replace them individually.

Meanwhile, a water filter apparatus according to another embodiment of the present invention is shown in FIG.

The water filter device according to another embodiment of the present invention shown in FIG. 11 differs from the above-described water filter device in that the configuration of the connection part 70 connecting the partition pipe 52 and the discharge port 14 is different Only the connecting portions shown in FIG. 11 will be described in the following.
