Description

Technology Field

[0001] This specification relates to a water purifier, and more specifically, to a cartridge-type connector for a water purifier that is replaceably mounted between a water purification filter and a water dispensing tap to prevent contamination of the water. Background Technology

[0002] Unless otherwise indicated in this specification, the contents described in this section are not prior art for the claims of this application, and are not to be recognized as prior art simply because they are included in this section.

[0004] Generally, water purifiers can ensure water purification hygiene above a certain level by replacing the water path at appropriate intervals to prevent harmful scale or bacteria generated inside the downstream water path of the water purification filter used to purify raw water such as tap water.

[0005] Although not shown in the drawing, when replacing the downstream water filter of a conventional water purifier, it is necessary to disassemble parts of the water path that needs to be replaced, remove connected fittings, and then separate and replace each part individually. This results in excessive work time and effort, as well as the problem of leakage occurring through the joints after the water path replacement work.

[0006] On the other hand, if the synthetic resin hose forming the downstream flow path of the water purification filter is replaced with a stainless steel pipe, water purification hygiene can be enhanced by sterilizing the inside of the pipe through the circulation of high-temperature steam or separate disinfectants at random intervals; however, this presents a limitation as it cannot completely sterilize scale or proliferating bacteria that form in the stainless steel flow path.

[0008] A one-touch type Euro replacement modular water purifier is disclosed in Korean Registered Patent Publication No. 10-1987942. The problem to be solved

[0009] The embodiments of this specification relate to a cartridge-type connector for a water purifier, which prevents water purification due to scale, etc., by replacing a connector that is installed between a water purification filter and a water outlet tap to form a flow path.

[0012] A case in which a raw water inlet is formed at one end and a purified water outlet is formed at the other end;

[0013] A raw water passage formed inside the above case and communicating with the raw water inlet, and a purified water passage communicating with the purified water outlet;

[0014] The present invention provides a cartridge-type connector for a water purifier characterized by including a coupling member that is connected to the raw water passage and the purified water passage, and to which one or more filter housings for filtering foreign substances in the raw water are each detachably coupled. Effects of the invention

[0015] A cartridge-type connector for a water purifier according to an embodiment of the present specification having the above-described configuration has the following advantages.

[0016] By replacing the connector installed between the water purification filter and the outlet cock, which forms the flow path for raw and purified water, contamination of the purified water due to scale and other factors can be prevented, thereby ensuring reliability.

[0017] In addition, even users without a certain level of technical expertise in water purifiers can easily replace the connector and water filter themselves using a one-touch method, providing practicality and convenience. Brief explanation of the drawing

Specific details for implementing the invention

[0019] Hereinafter, a cartridge-type connector for a water purifier according to a preferred embodiment of the present specification will be described in detail with reference to the attached drawings.

[0021] Referring to FIGS. 1 to 11, a cartridge-type connector for a water purifier according to one embodiment of the present specification is

[0022] A cylindrical case (12) having a raw water inlet (10) formed at one end and a purified water outlet (11) formed at the other end;

[0023] A raw water passage (13) formed inside the case (12) and communicating with the raw water inlet (10), and a purified water passage (14) communicating with the purified water outlet (11);

[0024] It is characterized by including a coupling member (16) in which one or more filter housings (15), each housing a water purification filter (not shown) that filters foreign substances in raw water and is connected to a raw water passage (13) and a purified water passage (14), are detachably coupled.

[0026] As shown in FIGS. 6 and 10, the aforementioned connector (17) is further characterized by including a water transfer channel (18) for a faucet (not shown) that is branched to a water transfer channel (14) to discharge water to a faucet.

[0027] As a result, a portion of the purified water that has been purified by the water purification filter of the aforementioned filter housing (15) can be discharged through the purified water transfer passage (14) and the water outlet tap (32) for drinking.

[0028] In addition, some of the purified water processed by the water purification filter of the filter housing (15) is discharged through the water purification passage (18) for the faucet, which is branched and connected to the water purification passage (14), and used as cooking water, thereby providing convenience and practicality to the user.

[0030] As shown in FIG. 3, by further including a handle (19) formed protruding from the water outlet (11) side of the aforementioned connector (17),

[0031] The connector (17) is detachably coupled to the upper cap (21) of the main body (20), and is characterized by being able to grip the connector (17) when coupling or detaching it.

[0032] As a result, when the aforementioned connector (17) is inserted into the upper cap (21) and then rotated at an arbitrary angle to be coupled to the coupling portion (30) of the main body (20) or separated from the coupling portion (30), the connector (17) can be easily pushed into the upper cap (21) or pulled out of the upper cap (21) by gripping the handle (19) formed on the water discharge portion (11) side of the connector (17).

[0034] As shown in FIG. 7 (a, b, c, d), by further including a catch groove (22) formed on one side of the outer circumference of the aforementioned case (12),

[0035] When the discharge port (23) of the filter housing (15) is detached from the coupling port (16) of the connector (17), the inner end of the stopper (24), which is rotatably mounted on the main body (20), is removed from the catch groove (22), thereby allowing the filter housing (15) to be received in an upright state on the main body (20), and when the inner end of the stopper (24) is seated in the catch groove (22), the filter housing (15) can be maintained in a state rotated at an arbitrary angle on the main body (20).

[0036] As a result, the discharge port (23) is connected to the coupling port (16) of the aforementioned connector (17), and the filter housing (15) housed in the storage space (33) of the main body (120) can be easily replaced.

[0037] To explain this in detail, as shown in the figure, the inner end of the "L" shaped stopper (24) rotatably formed on the upper cap (21) is detached from the catch groove (22) of the connector (17), so the filter housing (15) can rotate within any angle.

[0038] As shown in FIGS. 7b and 7d, when the filter housing (15) is grasped and lifted by rotating the connector (17) around the central axis, the inner end of the stopper (24) is coupled to the catch groove (22) of the connector (17).

[0039] As a result, the rotation of the connector (17), in which the discharge port (23) of the filter housing (15) is connected to the coupling port (16) of the connector (17), is stopped, so the filter housing (15) is positioned toward the door (34) while maintaining an angle of about 45 degrees (see FIG. 7b).

[0040] Therefore, the filter housing (15) can be separated from the coupling portion (16) of the connector (17), or a new filter housing (15) can be easily connected to the coupling portion (16).

[0041] As described above, after replacing the filter housing (15) with the connector (17), when the outer end of the stopper (24) is pressed toward the connector (17), the inner end of the stopper (24) is lifted by the elastic restoring force of the elastic member (35) and detached from the locking groove (22) of the connector (17).

[0042] Accordingly, the filter housing (15) is grasped and rotated with the connector (17) as the central axis so that it is lowered toward the rear wall of the main body (20) (i.e., in a direction away from the door (34)), thereby allowing it to be accommodated in the storage space (33) (see FIG. 7a).

[0043] At this time, the technical content of the discharge port (23) of the filter housing (15) being detachably locked to the coupling port (16) of the connector (17) by a rotary coupling method by means of the wing-shaped first locker (25) formed in the discharge port (23) of the filter housing (15) and the wing-shaped second locker (28) formed in the coupling port (16) of the connector (17) corresponding thereto is a configuration commonly used in the technical field to which this specification belongs, so a detailed description of these configurations is omitted.

[0045] As shown in FIG. 3, it is characterized by further including an O-ring (27) which is mounted on one side of the outer circumference of the aforementioned case (12) and supports the connector (17) so that it does not shake when the connector (17) is coupled to the upper cap (21) of the main body (20).

[0046] As a result, when the connector (17) is attached to the upper cap (21) of the main body (20), the connector (16) can be supported so as not to shake by the O-ring (27) mounted on one side of the outer circumference of the case (12).

[0048] As shown in FIGS. 3, 4, and 8c, by further including a wing-shaped first rocker (25) formed opposite to the inner surface of the coupling portion (16) of the aforementioned connector (17),

[0049] The filter housing (15) is characterized by being able to lock the filter housing (15) to the connector (17) by a rotational coupling method by means of a wing-shaped first rocker (25) and a wing-shaped second rocker (28) formed symmetrically on the outer surface of the discharge port (23) of the filter housing (15) in a corresponding manner when the discharge port (23) of the filter housing (15) is rotated at any angle.

[0050] The technical description of the discharge port (23) of the filter housing (15) being detachably locked to the coupling port (16) of the connector (17) by a rotary coupling method by means of the wing-shaped first locker (25) formed in the discharge port (23) of the filter housing (15) and the wing-shaped second locker (28) formed in the coupling port (16) of the connector (17) corresponding thereto is a configuration commonly used in the technical field to which this specification belongs, so a detailed description of these configurations is omitted.

[0052] As shown in FIG. 3 and 8b, by further including a wing-shaped third rocker (29) formed symmetrically on the outer surface of the raw water inlet (10) of the aforementioned connector (17),

[0053] The connector (17) is characterized by being able to lock the connector (17) to the main body (20) by a rotating coupling method when the raw water inlet (10) of the connector (17) is coupled to the coupling member (30) of the main body (20) and rotated at an arbitrary angle, by means of a wing-shaped third locker (29) and a wing-shaped fourth locker (31) formed opposite to the inner surface of the coupling member (30) of the main body (20) in a corresponding manner.

[0054] When the raw water inlet (10) of the aforementioned connector (17) is passed through the opening of the upper cap (21) and inserted into the coupling (30) formed in the main body (20), and the connector (17) is rotated at any angle, it is locked by the wing-shaped third locker (29) formed on the outer surface of the raw water inlet (10) and the wing-shaped fourth locker (31) formed on the inner surface of the coupling (30) of the main body (20) corresponding thereto.

[0055] At this time, when the raw water inlet (10) of the connector (17) is attached to and detached from the coupling (30) of the main body (20), the technical content of locking the connector (17) to the main body (20) in a one-touch manner by means of the wing-shaped third locker (29) of the connector (17) and the corresponding wing-shaped fourth locker (31) of the main body (20) is a configuration commonly used in the technical field to which this specification belongs, so a detailed description of these configurations is omitted.

[0057] As illustrated in FIG. 3, one or more first pockets (36) formed on the inner surface of the aforementioned door (34);

[0058] It is characterized by including a magnetic body (37) that is accommodated in the first pocket (36) and maintains the door (34) of the main body (20) in a closed state.

[0059] As a result, when the door (34) is closed on the main body (20), the door (34) can be prevented from being opened by means of the magnetic body (37) contained in the first pocket (36) formed on the edge of the door (34).

[0061] As illustrated in FIGS. 3 and 5, a magnetic body (39) accommodated in a second pocket (38) formed on one side of the inner surface of the aforementioned door (34);

[0062] By including a solenoid valve (41) formed to open and close the raw water inlet pipe (40) between the raw water inlet (10) and the raw water passage (13),

[0063] When the magnetic body moves away from the set distance from the plunger (41a) of the solenoid valve (41) by opening the door (34), the plunger (41a) switches to a close mode to close the raw water inlet pipe (40), and when the magnetic body (39) comes within the set distance of the plunger (41a) by closing the door (34), the plunger (41a) switches to an open mode to open the raw water inlet pipe (40).

[0064] As a result, when the door (34) is opened to replace the aforementioned filter housing (15), the raw water inlet pipe (40) is automatically closed by the solenoid valve (41) which switches to a closed mode, thereby providing convenience to the user.

[0065] At this time, the technical content of opening and closing the raw water inlet pipe (40) by means of a solenoid valve (41) that switches to an open mode or a closed mode as the magnetic body (39) moves away from or approaches the solenoid valve (41) within a set distance according to the opening and closing of the aforementioned door (34) is used in the technical field to which this specification belongs, so a detailed description of the configuration thereof is omitted.

[0067] As shown in FIGS. 3 and 6, the invention is characterized by including a tray (42) that is detachably formed on one side of the aforementioned main body (20) and collects water that falls in the form of water droplets after discharging water from the water outlet cock (32).

[0068] As a result, when drinking purified water by discharging it through the aforementioned water outlet (32), the purified water falling from the water outlet (32) in the form of water droplets can be collected and disposed of in the sink, thereby preventing contamination of the surroundings.

[0070] As shown in FIG. 8a, it is characterized by including a guide groove (44) formed opposite to the entrance side of the upper cap (21) to correspond to a reinforcing projection (43) formed to protrude outward from the coupling portion (16) of the aforementioned connector (17), and for guiding the coupling direction when coupling the connector (17) to the upper cap (21).

[0071] As a result, when the connector (17) is inserted into the inlet of the upper cap (21) to connect the raw water inlet (10) of the connector (17) to the coupling portion (30) of the main body (20) described above, the reinforcing projection (43) protruding from the outer surface of the cylindrical connector (17) can be passed through the guide groove (44) formed opposite to the inlet side of the upper cap (21) to allow it to be easily inserted into the upper cap (21).

[0073] It is characterized by further including a ceramic valve (not shown) formed in the aforementioned water purification outlet (11) and for discharging or blocking water purification when the on / off valve operating lever (46) is rotated to a set angle.

[0074] It is characterized by further including a check valve (not shown) formed in the coupling portion (16) of the aforementioned connector (17) to prevent leakage when the filter housing (15) is separated from the coupling portion (16).

[0075] The raw water inlet (10) of the aforementioned connector (17) is formed in a coupling member (30) to which it is detachably coupled, and further includes a check valve (30a) to prevent raw water from leaking out when the connector (17) is separated from the coupling member (30).

[0077] The aforementioned raw water inlet (10) is connected to an uppermost filter housing (15a) that is connected to the uppermost coupling (referring to the coupling closest to the raw water inlet (10)) among the couplings (16) (referring to the coupling located at the far right of the connector (17) in the drawing of FIG. 1), and

[0078] The outlet of the uppermost filter housing (15a) is connected to the inlet of the intermediate filter housing (15b), which is connected to the intermediate coupling (referring to the coupling located in the middle of the longitudinal direction of the connector (17) in the drawing of FIG. 1).

[0079] The outlet of the intermediate filter housing (15b) is connected to the inlet of the lowest-downstream filter housing (15c), which is connected to the lowest-downstream coupling (16) (referring to the coupling closest to the purified water outlet (11)) (referring to the coupling located on the far left of the connector (17) in the drawing of FIG. 1).

[0080] The outlet of the downstream filter housing (15c) is connected to the water purification outlet (11).

[0081] At this time, the filter housing (15; 15a, 15b, 15c) is detachably coupled to the three coupling portions (16) formed longitudinally on the aforementioned connector (17) to form a three-stage type, but this is an example and is not limited thereto, and it is obvious that it can be implemented in a multi-stage type depending on the size of the water purifier.

[0083] In the drawing, the unexplained reference numeral 45 is a water outlet cock cap that is detachably coupled to the inlet side of the upper cap (21), 46 is an on / off valve operating lever for controlling the discharge of purified water through the water outlet cock (45), and 49 is a leg for supporting the main body (20) while it is standing upright on the sink.

[0085] Hereinafter, an example of use of a cartridge-type connector for a water purifier according to one embodiment of the present specification is described with reference to the attached drawings.

[0087] As shown in FIGS. 1 to 11, raw water such as tap water passes sequentially through a raw water inlet (10) formed on one side of the lower part of the main body (20), a pressure reducing valve (47), a raw water inlet pipe (40), and an open solenoid valve (41), and then passes through a coupling (30) formed in the main body (20) to which the raw water inlet (10) of the connector (17) is coupled, and moves to the connector (17).

[0088] Three filter housings (15; 15a, 15b, 15c) are connected to the aforementioned connector (17) and are accommodated in the storage space (33) of the main body (20). As an example, in the drawing of FIG. 2, the filter housing (15a) is accommodated on the right side of the storage space (33), and the filter housing (15c) is accommodated on the left side of the storage space (33) (referring to the side of the water outlet cock (32)).

[0089] As the raw water transferred to the aforementioned connector (17) flows into the water purification filter through the inlet port (P1) formed in the center of the discharge port (23) of the filter housing (15a), the foreign substances harmful to the human body contained in the raw water are purified by the water purification filter (not shown) inside.

[0090] The purified water, which has been purified by the primary purification filter of the filter housing (15a), is discharged through the discharge port (a1) formed outside the inlet port (P1) and moved to the raw water passage (13a).

[0091] The primary purified water transferred to the raw water transfer passage (13a) flows into the water purification filter through the inlet port (P2) formed in the center of the discharge port (23) of the filter housing (15b) connected to the raw water transfer passage (13a). Thus, the purified water transferred after primary purification is subjected to secondary purification by the water purification filter (not shown) of the filter housing (15b).

[0092] The purified water, which has undergone secondary purification by the water purification filter of the filter housing (15b), is discharged through the discharge port (a2) formed outside the inlet port (P2) and moved to the raw water passage (13b).

[0093] The secondary purified water transferred to the raw water transfer passage (13b) flows into the water purification filter through the inlet port (P3) formed in the center of the discharge port (23) of the filter housing (17c) connected to the raw water transfer passage (14b). Thus, the purified water transferred after secondary purification is subjected to tertiary purification by the water purification filter (not shown) of the filter housing (17c).

[0094] The purified water, which has been purified three times by the water purification filter of the filter housing (15c), is discharged through the discharge port (a3) ​​formed outside the inlet port (P3) and moved to the purified water passage (14) connected to the discharge port (a3).

[0095] After the purified water moved in the purified water transfer passage (14) is moved to the on / off valve (48) formed in the purified water outlet (11) of the connector (17), the user operates the on / off valve operating lever (46) to the open position to switch the on / off valve (48) to the open state, thereby allowing the purified water to be discharged through the water outlet cock (32) connected to the purified water outlet (11).

[0096] Therefore, the user can drink the purified water discharged through the water outlet (32) using a cup (not shown).

[0097] Meanwhile, the purified water that has undergone third purification treatment and is discharged through the discharge port (a3) ​​is discharged through the purified water transfer passage (18) for the faucet connected to the discharge port (a3), so it can be used as cooking water.

[0098] As described above, when a connector (17) formed of a synthetic resin material to which a three-stage filter housing (15) is detachably coupled is used repeatedly, water stains may form in the raw water passage (13) and purified water passage (14) formed in the connector (17), and bacteria harmful to the human body may proliferate.

[0099] At this time, the user can be protected from the source of contamination by completely separating the connector (17) from the main body (20) and replacing it with a new one.

[0100] To explain this in detail, the filter housing (15) is separated from the connector (17) coupled to the upper cap (21) described above.

[0101] As illustrated in FIG. 9, by rotating the water outlet cock (32) by an arbitrary angle, the wing-shaped rocker (32a) formed on the upper outer surface of the water outlet cock (32) can be unlocked from the wing-shaped rocker (32a) formed on the inner circumference of the through hole (45b) formed on the bottom surface of the water outlet cock cap (45) correspondingly. Thus, the water outlet cock (32) can be separated from the water outlet cock cap (45).

[0102] Next, the on / off valve operating lever (46), which is screw-coupled to the on / off valve (48), can be separated from the on / off valve (48).

[0103] Accordingly, the water outlet cap (45) that is in close contact with the inlet side of the upper cap (21) can be separated in a one-touch manner by pulling it outward. That is, the water outlet cap (45) can be separated from the upper cap (21) as the magnetic force of the magnetic body (45d) contained in the pocket (45c) formed on the opening contact surface of the water outlet cap (45) is lost.

[0104] As described above, after separating the water outlet cap (45) from the upper cap (21), if the connector (17) is rotated in one direction within an arbitrary angle range by gripping the handle (19) formed on the outer end of the connector (17) (referring to the side opposite the raw water inlet (10)), the raw water inlet (10) of the connector (17) locked to the coupling part (30) of the main body (20) by the third and fourth rockers (29, 31) can be unlocked.

[0105] Therefore, the entire connector (17) can be separated from the main body (20) by pulling it toward the entrance of the upper cap (21).

[0106] After separating the entire contaminated connector (17) from the main body (20), a new connector (17) can be inserted through the opening of the upper cap (21) and coupled and locked to the coupling portion (30) of the main body (20).

[0107] As described above, the hygiene of the water purification system can be improved by replacing the entire connector (17) located downstream of the filter housing (15), which may become contaminated as the water purifier is used repeatedly.

[0109] Hereinafter, although the foregoing specification has been described with reference to preferred embodiments, those skilled in the art will understand that various modifications and changes can be made to the specification without departing from the spirit and scope of the specification as set forth in the following claims.
