Description

Powerless water purifier

[0001] This specification relates to a water purifier, and more specifically, to a power-free water purifier designed to minimize contamination of potable water by replacing the water flow path (referring to the connector) between the water purification filter and the water outlet tap.

[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.

[0003] 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.

[0004] 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.

[0005] 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.

[0006] A one-touch type Euro replacement modular water purifier is disclosed in Korean Registered Patent Publication No. 10-1987942.

[0007] The embodiments of this specification relate to a non-powered water purifier that prevents water contamination caused by scale, etc., by replacing the entire flow path (referring to the connector) between the water purification filter and the water outlet tap.

[0008] The embodiments of this specification relate to a non-powered water purifier that allows a user to directly replace a connector and a water filter with a single touch.

[0009] According to one embodiment of the present specification, in order to achieve the above and other purposes of the present specification,

[0010] A main body having a door formed on one side that can be opened and closed, and a storage space formed inside;

[0011] A connector that is replaceably and rotatably coupled to one side of the main body and has a raw water passage connected to a raw water inlet and a purified water passage formed therein for moving purified water;

[0012] One or more filter housings, each having a discharge port detachably coupled to the connector and accommodated in the storage space;

[0013] A water purifier without power is provided, characterized by including a water outlet tap connected to the outlet of the connector and discharging purified water.

[0014] A power-free water purifier according to an embodiment of the present specification having the above-described configuration has the following advantages.

[0015] By replacing the entire water flow path (referring to the connector) between the water purification filter and the water outlet tap, it becomes possible to prevent water contamination caused by foreign substances harmful to the human body, such as scale and bacteria, that accumulate inside the flow path.

[0016] In addition, even users without specialized knowledge of water purifiers can directly replace the connector and water filter using a one-touch method, providing convenience, practicality, and reliability.

[0046] Hereinafter, a power-free water purifier according to a preferred embodiment of the present specification will be described in detail with reference to the attached drawings.

[0047] Referring to FIGS. 1 to 10, a power-free water purifier according to one embodiment of the present specification is

[0048] A main body (12) having a door (10) formed on one side that can be opened and closed, and a storage space (11) formed inside;

[0049] A cylindrical connector (16) that is interchangeably and rotatablely coupled to one side of the upper part of the main body (12) within an arbitrary angle, and has a raw water passage (14) formed on one side of the main body (12) and connected to a raw water inlet (13) through which raw water such as tap water flows in, and a purified water passage (15) through which purified water flows;

[0050] A nipple-shaped discharge port (30) is detachably coupled to a connector (16) and accommodated in a storage space (11), and one or more filter housings (17) for filtering foreign substances contained in raw water flowing in through a raw water inlet (13);

[0051] It is characterized by including a water outlet cock (19) that is connected to the outlet (18) of the connector (16) and discharges purified water.

[0052] According to a more preferred embodiment, as shown in FIGS. 6a, 6b, 7a, and 7b, an upper cap (20) formed on the main body (12) to surround the upper part of the aforementioned connector (16);

[0053] A stopper (22) rotatably formed on an upper cap (20) such that its inner end is detachably coupled to a locking groove (21) formed on the outer circumference of a connector (16), and when the outer end is pressed, the inner end detaches from the locking groove (21);

[0054] It is further characterized by including an elastic member (23) that elastically biases the middle side of the stopper (22) to the initial state so that the inner end is coupled to the catch groove (21) (for example, a compression coil spring may be used).

[0055] As a result, the discharge port (30) is connected to the coupling port (32) of the aforementioned connector (16), and the filter housing (17) accommodated in the storage space (11) of the main body (12) can be easily replaced.

[0056] To explain this in detail, as shown in FIG. 6a, the inner end of the "L" shaped stopper (22) rotatably formed on the upper cap (20) is detached from the catch groove (21) of the connector (16), so the filter housing (17) can rotate within any angle.

[0057] As shown in FIG. 6b, when the filter housing (17) is grasped and lifted by rotating the connector (16) around the central axis, the inner end of the stopper (22) is coupled to the catch groove (21) of the connector (16).

[0058] As a result, the rotation of the connector (16), to which the discharge port (30) of the filter housing (17) is connected to the coupling member (32), is stopped, so the filter housing (17) is positioned toward the door (10) while maintaining an angle of about 45 degrees (see FIG. 6b).

[0059] Accordingly, the filter housing (17) can be separated from the coupling portion (32) of the connector (16), or a new filter housing (17) can be coupled to the coupling portion (32).

[0060] As described above, after replacing the filter housing (17) in the connector (16), when the outer end of the stopper (22) is pressed toward the connector (16), the inner end of the stopper (22) is lifted by the elastic restoring force of the elastic member (23) and detached from the locking groove (21) of the connector (16).

[0061] Accordingly, the filter housing (17) is grasped and rotated with the connector (16) as the central axis so that it is lowered toward the rear wall of the main body (12) (i.e., in a direction away from the door (10)), thereby allowing it to be accommodated in the storage space (11) (see FIG. 6a).

[0062] At this time, the technical description of detachably locking the discharge port (30) of the filter housing (17) to the coupling port (32) of the connector (16) by means of the first rocker (31) formed in the discharge port (30) of the filter housing (17) and the second rocker (33) formed in the coupling port (32) of the connector (16) 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.

[0063] As illustrated in FIG. 3, one or more first pockets (24) formed on the inner surface of the aforementioned door (10);

[0064] It is characterized by further including a magnetic body (25) that is accommodated in the first pocket (24) to maintain the door (10) in a closed state on the main body (12).

[0065] As a result, when the door (10) is closed on the main body (12), the door (10) can be prevented from being opened by means of the magnetic body (25) contained in the first pocket (24) formed on the edge of the door (10).

[0066] As illustrated in FIGS. 4 and 5, a magnetic body (27) accommodated in a second pocket (26) formed on one side of the inner surface of the aforementioned door (10);

[0067] By further including a solenoid valve (47) formed to open and close the raw water inlet pipe (46) between the raw water inlet (13) and the raw water passage (14),

[0068] When the magnetic body moves away from the set distance from the plunger (47a) of the solenoid valve (47) by opening the door (10), the plunger (47a) switches to a close mode to close the raw water inlet pipe (46), and when the magnetic body (27) comes within the set distance of the plunger (47a) by closing the door (10), the plunger (47a) switches to an open mode to open the raw water inlet pipe (46).

[0069] As a result, when the door (10) is opened to replace the aforementioned filter housing (17), the raw water inlet pipe (46) is automatically closed by the solenoid valve (47) which switches to a closed mode, thereby providing convenience to the user.

[0070] At this time, the technical content of opening and closing the raw water inlet pipe (46) by means of a solenoid valve (47) that switches to an open mode or a closed mode as the magnetic body (27) moves away from or approaches the solenoid valve (47) within a set distance according to the opening and closing of the aforementioned door (10) is used in the technical field to which this specification belongs, so a detailed description of the configuration thereof is omitted.

[0071] As illustrated in FIGS. 3 and 8c, the coupling method of the filter housing (17), in which the discharge port (30) is detachably locked to the aforementioned connector (16), is

[0072] A wing-shaped first rocker (31) formed symmetrically on the outer surface of the discharge port (30) of the filter housing (17);

[0073] Further including a wing-shaped second rocker (33) formed opposite to the inner surface of the coupling portion (32) of the connector (16) to which the discharge port (30) is coupled.

[0074] It is characterized by a rotary coupling method in which, when the discharge port (30) of the filter housing (17) is inserted into the coupling port (32) of the connector (16) and rotated at any angle, the wing-shaped first rocker (31) is detachably locked to the wing-shaped second rocker (33).

[0075] As a result, when the discharge port (30) of the corresponding filter housing (17) is coupled to the coupling port (32) of the aforementioned connector (16) and the filter housing (17) is rotated within an arbitrary angle, the wing-shaped first rocker (31) of the filter housing (17) is locked by the wing-shaped second rocker (33) of the corresponding connector (16).

[0076] At this time, when attaching or detaching the filter housing (17) to the connector (16), the technical content of locking the filter housing (17) to the connector (16) in a one-touch manner by means of the wing-shaped first locker (31) of the filter housing (17) and the corresponding wing-shaped second locker (33) of the connector (16) is a configuration commonly used in the technical field to which this specification belongs, so a detailed description of these configurations is omitted.

[0077] Although not shown in the drawing, the coupling method of the filter housing (17) that is detachably locked to the aforementioned connector (16) is

[0078] A push button (not shown) formed on one side of the outer surface of the connector (16);

[0079] A pair of rockers (not shown) formed in the coupling portion (32) of the connector (16) to expand radially in response to push button pressure;

[0080] It is characterized by a push button type coupling method including an annular locking projection formed on the outer surface of the discharge port (30) of the filter housing (17) and detachably locked by a rocker.

[0081] As a result, when the discharge port (30) of the corresponding filter housing (17) is coupled to the coupling portion (32) of the aforementioned connector (16), the rocker formed in the coupling portion (32) of the connector (16) opens outward and then returns to its initial state by the elastic restoring force of the elastic member, thereby enabling the locking projection formed in the discharge port (30) of the filter housing (17) to be locked.

[0082] At this time, when attaching or detaching the filter housing (17) to the aforementioned connector (16), the technical description of locking the filter housing (17) to the connector (16) in a one-touch manner by means of the annular locking projection of the filter housing (17) and the structure of the rocker of the connector (16) 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.

[0083] As shown in FIG. 3 and FIG. 8a, it is characterized by further including a guide groove (35) formed opposite to the inlet side of the upper cap (20) to correspond to a reinforcing projection (34) formed to protrude outward from the coupling portion (32) of the aforementioned connector (16), and for guiding the coupling direction when coupling the connector (16) to the upper cap (20).

[0084] As a result, when inserting the connector (16) into the inlet of the upper cap (20) to connect the inlet (36) of the connector (16) to the coupling portion (38) of the main body (12) described above, the reinforcing projection (34) protruding from the outer surface of the cylindrical connector (16) can be passed through the guide groove (35) formed opposite to the inlet side of the upper cap (20) to allow it to be easily inserted into the upper cap (20).

[0085] As illustrated in FIGS. 3 and FIGS. 8b, the coupling method of the connector (16) that is replaceably locked to the aforementioned main body (12) is

[0086] A wing-shaped third rocker (37) formed symmetrically on the outer surface of the inlet (36) of the connector (16);

[0087] Further including a wing-shaped fourth rocker (39) formed opposite to the inner surface of the boss-shaped coupling portion (38) of the main body (12) to which the inlet (36) of the connector (16) is coupled.

[0088] It is characterized by a rotary coupling method in which the wing-shaped third locker (37) is detachably locked to the wing-shaped fourth locker (39) when the inlet (36) of the connector (16) passes through the inlet of the upper cap (20) and is coupled to the coupling member (38) of the main body (12) and rotated at any angle.

[0089] As a result, when the inlet (36) of the aforementioned connector (16) is passed through the opening of the upper cap (20) and inserted into the coupling (38) formed in the main body (12), and the connector (16) is rotated at any angle, it is locked by the wing-shaped third locker (37) formed on the outer side of the inlet (36) and the wing-shaped fourth locker (39) formed on the inner side of the coupling (38) of the main body (12) corresponding thereto.

[0090] At this time, when the inlet port (36) of the connector (16) is attached to and detached from the coupling port (38) of the main body (12), the technical content of the connector (16) being attached to and detached from the main body (12) in a one-touch manner by means of the wing-shaped third locker (37) of the connector (16) and the corresponding wing-shaped fourth locker (39) of the main body (12) is a configuration commonly used in the technical field to which this specification belongs, so a detailed description of these configurations is omitted.

[0091] As illustrated in FIG. 5, the aforementioned connector (16) is further characterized by including a water transfer channel (40) for a faucet that is branched to the water transfer channel (15) to discharge water to the faucet.

[0092] As a result, a portion of the purified water that has been purified by the water purification filter of the aforementioned filter housing (17) can be discharged through the purified water transfer passage (15) and the water outlet tap (19) for drinking.

[0093] In addition, some of the purified water processed by the water purification filter of the filter housing (17) is discharged through the water purification passage (40) for the faucet, which is branched and connected to the water purification passage (15), and used as cooking water, thereby providing convenience and practicality to the user.

[0094] As illustrated in FIGS. 1 to 5, the invention is characterized by further including a tray (41) that is detachably formed on one side of the aforementioned main body (12) and is used to collect water that falls in the form of water droplets after discharging water from the water outlet cock (19).

[0095] As a result, when drinking purified water by discharging it through the aforementioned water outlet tap (19), the purified water falling from the water outlet tap (19) in the form of water droplets can be collected and disposed of in the sink, thereby preventing contamination of the surroundings.

[0096] As shown in FIG. 3, the aforementioned connector (16) is

[0097] It is characterized by further including a handle (42) formed protruding from one side of the connector (16) and used to grip the connector (16) when connecting or disconnecting it from the upper cap (20).

[0098] As a result, when the connector (16) is inserted into the upper cap (20) and then rotated at an arbitrary angle to connect to the coupling portion (38) of the main body (12) or to detach from the coupling portion (38), the connector (16) can be easily pushed into the upper cap (20) or pulled out by gripping the handle (42) formed on the discharge portion (18) side.

[0099] Although not shown in the drawing, the raw water inlet (36) of the aforementioned connector (16) is formed in the coupling portion (38) of the main body (12) to which it is detachably coupled, and the device further includes a check valve (38a) to prevent raw water from leaking out when the connector (16) is separated from the coupling portion (38).

[0100] As a result, when the connector (16) is separated from the main body (12) to replace it, the outlet side of the raw water inlet pipe (46) is blocked by the check valve (38a) installed in the coupling (38), thereby preventing contamination caused by raw water leaking into the main body (12).

[0101] In the drawing, the unexplained reference numeral 43 is a water outlet cock cap that is detachably coupled to the inlet side of the upper cap (20), 44 is an on / off valve operating lever for controlling the discharge of purified water through the water outlet cock (19), 45 is a leg for supporting the main body (12) while it is standing upright on the sink, and 50 is an O-ring for supporting the connector (16) that is mounted on the inlet side of the connector (16) and coupled to the upper cap (20).

[0102] Hereinafter, an example of use of a power-free water purifier according to one embodiment of the present specification is described with reference to the attached drawings.

[0103] As shown in FIGS. 1 to 10, raw water such as tap water passes sequentially through a raw water inlet (13) formed on one side of the lower part of the main body (12), a pressure reducing valve (47), a raw water inlet pipe (46), and an open solenoid valve (47), and then passes through a coupling part (38) formed on the main body (12) to which the inlet (36) of the connector (16) is coupled, and moves to the connector (16).

[0104] Three filter housings (17; 17a, 17b, 17c) are connected to the aforementioned connector (16) and are accommodated in the storage space (11) of the main body (12). As an example, in the drawing of FIG. 2, the filter housing (17a) is accommodated on the right side of the storage space (11), and the filter housing (17c) is accommodated on the left side of the storage space (11) (referring to the side of the water outlet cock (19)).

[0105] As the raw water transferred to the aforementioned connector (16) flows into the water purification filter through the inlet port (P1) formed in the center of the discharge port (30) of the filter housing (17a), the foreign substances harmful to the human body contained in the raw water are purified by the water purification filter (not shown) inside.

[0106] The purified water, which has been purified by the primary purification filter of the filter housing (17a), is discharged through the discharge port (a1) formed outside the inlet port (P1) and moved to the raw water passage (14a).

[0107] The primary purified water transferred to the raw water transfer passage (14a) flows into the water purification filter through the inlet port (P2) formed in the center of the discharge port (30) of the filter housing (17b) connected to the raw water transfer passage (14a). Thus, the purified water transferred after primary purification is subjected to secondary purification by the water purification filter (not shown) of the filter housing (17b).

[0108] The purified water, which has undergone secondary purification by the water purification filter of the filter housing (17b), is discharged through the discharge port (a2) formed outside the inlet port (P2) and moved to the raw water passage (14b).

[0109] The secondary purified water transferred to the raw water transfer passage (14b) flows into the water purification filter through the inlet port (P3) formed in the center of the discharge port (30) 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).

[0110] The purified water, which has been purified three times by the water purification filter of the filter housing (17c), is discharged through the discharge port (a3) ​​formed outside the inlet port (P3) and moved to the purified water passage (15) connected to the discharge port (a3).

[0111] After the purified water moved in the purified water transfer passage (15) is moved to the on / off valve (49) formed in the outlet (18) of the connector (16), the purified water can be discharged through the water outlet cock (19) connected to the outlet (18) by switching the on / off valve (49) to an open state by operating the on / off valve operating lever (44) to an open position by the user.

[0112] Therefore, the user can drink the purified water discharged through the water outlet tap (19) using a cup (not shown).

[0113] 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 (40) for the faucet connected to the discharge port (a3), so it can be used as cooking water.

[0114] As described above, when a connector (16) formed of synthetic resin material with a three-stage filter housing (17) detachably coupled thereto is repeatedly used, water stains may form in the raw water passage (14) and purified water passage (15) formed in the connector (16), and bacteria harmful to the human body may proliferate.

[0115] At this time, the user can be protected from the source of contamination by completely separating the connector (16) from the main body (12) and replacing it with a new one.

[0116] To explain this in detail, the filter housing (17) is separated from the connector (16) coupled to the upper cap (20) described above.

[0117] As illustrated in FIGS. 1, 3 and 8d, by rotating the water outlet cock (19) by an arbitrary angle, the wing-shaped rocker (19a) formed on the upper outer surface of the water outlet cock (19) can be unlocked from the wing-shaped rocker (43a) formed on the inner circumference of the through hole (43b) formed on the bottom surface of the water outlet cock cap (43) correspondingly. Thus, the water outlet cock (19) can be separated from the water outlet cock cap (43).

[0118] Next, the on / off valve operating lever (44), which is screw-coupled to the on / off valve (49), can be separated from the on / off valve (49).

[0119] Accordingly, the water outlet cap (43) that is in close contact with the inlet side of the upper cap (20) can be separated in a one-touch manner by pulling it outward. That is, the water outlet cap (43) can be separated from the upper cap (20) as the magnetic force of the magnetic body (43d) contained in the pocket (43c) formed on the opening contact surface of the water outlet cap (43) is lost.

[0120] As described above, after separating the outlet cock cap (43) from the upper cap (20), if the connector (16) is rotated in one direction within an arbitrary angle range by gripping the handle (42) formed on the outer end of the connector (16) (referring to the side opposite the inlet (36)), the inlet (36) of the connector (16) locked to the coupling (38) of the main body (12) by the third and fourth rockers (37, 39) can be unlocked.

[0121] Therefore, the entire connector (16) can be separated from the main body (12) by pulling it toward the entrance of the upper cap (20).

[0122] After separating the entire contaminated connector (16) from the main body (12), a new connector (16) can be inserted through the opening of the upper cap (20) and coupled and locked to the coupling portion (38) of the main body (12).

[0123] As described above, the hygiene of the water purifier can be improved by replacing the entire connector (16) located downstream of the filter housing (17), which may become contaminated as the water purifier is used repeatedly.

[0124] 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.

[0125] According to the present invention having the aforementioned configuration, the entire water flow path between the water purification filter and the water outlet tap is replaced, thereby preventing contamination of the water purification water by foreign substances harmful to the human body, such as scale and bacteria, that accumulate inside the flow path. Furthermore, even users without specialized knowledge of water purifiers can directly replace the connector and water purification filter using a one-touch method.
