Description

water purification device

[0001] The present invention relates to a water purification device equipped with a filter.

[0002] Water dispensing devices, such as water purifiers and refrigerators, refer to devices that purify raw water, such as tap water or groundwater. In other words, they refer to devices designed to convert raw water into drinking water and provide it through various purification methods.

[0003] To produce purified water, processes such as sedimentation, filtration, and sterilization may be performed, and it is common for harmful substances to be removed through these processes.

[0004] Generally, water dispensing devices may be equipped with various filters to purify raw water. These filters can be classified according to their function into sediment filters, activated carbon filters, UF hollow fiber membrane filters, RO membrane filters, etc.

[0005] The above sediment filter can be described as a filter for settling large particles of contaminants or suspended matter in raw water, and the activated carbon filter can be described as a filter for adsorbing and removing small particles of contaminants, residual chlorine, volatile organic compounds, or odor-causing agents.

[0006] In addition, the above-mentioned activated carbon filter may generally be provided in two units. That is, it may be provided with a pre-activated carbon filter provided on the raw water side and a post-activated carbon filter provided on the purified water side. The post-activated carbon filter may be provided primarily to improve the taste of the water by removing odor-causing substances that affect the taste of the purified water.

[0007] In addition, it is common for UF hollow fiber membrane filters and RO membrane filters to be used selectively.

[0008] Korean Published Patent Application No. 10-2017-0109987 (hereinafter, prior art) discloses a water purification device and a refrigerator equipped with a water purification device.

[0009] The refrigerator comprises: a filter that purifies incoming water and discharges it; a head that includes an inlet for receiving raw water and an outlet for discharging purified water, to which the filter is detachably coupled; a shaft that is rotatably mounted between the inlet and the outlet inside the head, and has a filtering path formed therein so that water received through the inlet passes through the filter and is discharged to the outlet, and a bypass path formed therein directly connecting the inlet and the outlet; a first connecting part provided at one end of the filter; and a second connecting part formed in a shape corresponding to the first connecting part at the center of rotation of the shaft and coupled to the first connecting part when the filter is mounted; wherein the shaft is rotated according to the rotation operation of the filter so that the filtering path or the bypass path is connected to the inlet and the outlet.

[0010] In the case of the aforementioned prior art, in order to attach a filter head to a filter bracket, the structure is provided to push the filter head into the filter bracket and then rotate the filter head.

[0011] At this time, since the filter head is inserted into the filter bracket via a press-fit method and then rotated, friction occurs between the parts, increasing the tightening torque. This results in a problem where significant force is required during filter replacement, raising the difficulty of the operation, and that filter replacement is only possible when a professional manager visits.

[0012] In addition, there were cases where the water flow was connected even if the filter head was not attached to the filter bracket, causing unfiltered tap water to flow through the outlet nozzle and resulting in the user drinking the tap water.

[0013] In addition, when the filter head is not fully attached to the filter, the flow path becomes blocked, preventing water flow and increasing internal water pressure, which leads to problems such as parts breakage or leakage, and there is also a problem where water does not discharge through the outlet nozzle.

[0014] In addition, due to the rotary detachable structure, the number of components installed in the center of the filter head where water flows, such as shafts, increased, which increased resistance to water flow and caused problems such as leakage or a decrease in treatment flow rate.

[0015] In addition, since a structure was not applied to hold the filter so that it would not detach from the filter head, there was a problem where the filter body separated from the filter head when removing the filter head from the filter bracket or when attaching the filter head to the filter bracket.

[0016] The present invention proposes a water purification device in which the structure of the filter head and filter bracket is simple, and the mutual connection between them can be easily and conveniently achieved.

[0017] The present invention proposes a water purification device in which filter replacement can be performed easily and conveniently using a push-pull method of pressing and pulling, thereby reducing the difficulty of the task and allowing the user to directly replace the filter when necessary.

[0018] In addition, we propose a water purification device that can lower flow resistance, increase processing flow rate, and reduce the risk of leakage by reducing the number of parts, such as shafts, placed in the water flow path.

[0019] In addition, the present invention proposes a water purification device in which, even if the fixing means is lifted by mistake, the filter head does not immediately detach from the filter bracket but remains connected to prevent leakage, and the filter head can be detached from the filter bracket only when the fixing means is lifted while rotating it beyond a certain angle, as the intention to detach the filter head is clear.

[0020] A water purification device according to the present invention comprises a filter body in which a filter material is received, a filter head provided at the top of the filter body, and a filter bracket to which the filter head is coupled and which is connected to a water supply channel into which raw water flows.

[0021] It includes a fixing means rotatably coupled to the filter bracket.

[0022] When the above fixing means rotates to one side, the filter head moves toward the filter bracket and is coupled, and when the above fixing means rotates to the other side opposite to the one side, the filter head separates from the filter bracket and is detached.

[0023] The filter bracket has shaft portions extending outwardly formed on both sides, and the fixing means has shaft grooves formed on both sides into which the shaft portions are rotatably fitted.

[0024] The above fixing means forms a front portion that is convexly formed forward and a pair of side portions extending rearward from both sides of the front portion.

[0025] The above side portions form shaft protrusions that protrude inwardly on surfaces facing each other, and the shaft groove is formed concavely inwardly on the inner surface of the shaft protrusions.

[0026] The above side portions form an extension rib extending downward from the shaft projection on the inner surface facing each other.

[0027] The above extension rib has a forward convex arc shape.

[0028] A retaining rib formed on the above extension rib is formed on the outer side in a convex shape.

[0029] The above-mentioned locking rib is formed at the connection point between the above-mentioned extension rib and the shaft projection.

[0030] The above-mentioned catch rib is formed at a certain distance from the connection portion between the above-mentioned extension rib and the shaft projection.

[0031] On both ends of the filter head, a pressing projection protruding outward is formed.

[0032] When the above fixing means rotates to one side, the locking rib pushes the pressing projection, and the filter head is separated from the filter bracket.

[0033] When the fixing means rotates to one side by a first angle, the locking rib contacts the pressing projection, and when the fixing means rotates to one side by a second angle greater than the second angle, the locking rib pushes the pressing projection, and the filter head is separated from the filter bracket.

[0034] A stopper is formed extending outward from one side of the shaft projection, and a catch portion is formed on the filter bracket that protrudes outwardly so that the stopper catches when the fixing means rotates upward, thereby restricting the rotation of the fixing means.

[0035] The above front portion and the above side portion form an upper surface portion extending inward from the top, and when the above fixing means rotates from the upper side to the lower side, the upper surface portion contacts the upper surface of the filter head.

[0036] When the above fixing means is rotated from the upper side to the lower side, the front part of the above fixing means comes into contact with the front of the filter head and moves the filter head by pushing it backward.

[0037] The filter head includes an inlet pipe that protrudes outward and extends horizontally to allow water to flow in, and an outlet pipe that protrudes outward and extends parallel to the inlet pipe to allow water to be discharged.

[0038] The filter bracket includes a first groove formed horizontally to allow the inlet pipe to be inserted horizontally, and a second groove extended horizontally to allow the outlet pipe to be inserted horizontally, and the filter head is connected to or separated from the filter bracket in a horizontal direction.

[0039] According to the present invention, the structure of the filter head and the filter bracket is simple, and has the effect of allowing easy and convenient mutual connection.

[0040] In addition, the push-pull method allows for easy and convenient filter replacement, reducing the difficulty of the task and enabling the user to replace the filter directly when necessary.

[0041] In addition, by reducing the number of parts, such as shafts, placed in the water flow path, flow resistance can be lowered, processing flow rate can be increased, and the risk of leakage can be reduced.

[0042] In addition, even if the fixing means is lifted by mistake, the filter head does not immediately detach from the filter bracket but remains connected, thereby preventing leakage. Furthermore, since the intention to detach the filter head is clear, the filter head can be detached from the filter bracket only when the fixing means is lifted while rotating it beyond a certain angle.

[0063] Specific embodiments of the present invention will be described in detail below with reference to the drawings. However, the concept of the present invention is not limited to the embodiments presented below, and those skilled in the art who understand the concept of the present invention may easily implement other embodiments included within the scope of the same concept by adding, changing, deleting, and adding components, and such are also to be considered to be included within the scope of the concept of the present invention.

[0064] The drawings attached to the following embodiments are embodiments of the same inventive concept, but in order to facilitate easy understanding without compromising the inventive concept, the representation of fine details may differ from drawing to drawing, and certain parts may not be shown in some drawings or may be exaggerated in others.

[0065] FIG. 1 is a perspective view of a water purification device according to one embodiment of the present invention. FIG. 2 is a drawing showing the state in which the front panel is separated from FIG. 1.

[0066] The water purification device according to the present invention is designed to purify water supplied from an external water source and then discharge it immediately, or to discharge it after cooling or heating, and may, for example, mean a direct-flow water purifier.

[0067] Here, a direct-flow water purifier refers to a type of water purifier that does not have a reservoir to store purified water; instead, water passes through a filter in real time upon a user's request for purification, and purified water is dispensed.

[0068] In addition, the water purification device according to the present invention may refer to a refrigerator having a water purification function. That is, it may refer to a water purification device refrigerator that is a refrigerator and is equipped with a filter for purifying raw water and a water outlet nozzle for dispensing purified water.

[0069] In addition, the water purification device according to the present invention may refer to an under-sink type water purifier in which the main body is installed at the bottom of the sink and the water outlet nozzle is installed on the outside of the sink.

[0070] In addition, the water purification device according to the present invention may refer to various known types of devices that receive water from a water source, purify it by passing it through a filter, and then supply it to the outside.

[0071] Referring to FIGS. 1 and 2, a water purification device according to one embodiment of the present invention includes a water purification device body (100) and a water discharge module (200) coupled to the water purification device body (100) and having a water discharge nozzle (300) mounted at the bottom.

[0072] In addition, a filter is arranged inside the main body (100) of the water purification device to receive water supplied from the outside and filter it into purified water.

[0073] Inside the main body (100) of the water purification device, a filter receiving space (101) in which the filter (120) is received is formed concavely in the rearward direction at a position adjacent to the front panel (112) forming the front of the main body (100) of the water purification device. Accordingly, when a user removes the front panel (112), the filter receiving space (101) and the filter (120) placed in the filter receiving space (101) can be exposed to the outside.

[0074] A filter bracket (130) is placed on the upper side of the filter receiving space (101).

[0075] And, when the front panel (112) is separated from the water purification device body (100), the filter (120) and the filter bracket (130) are exposed to the outside of the front.

[0076] Accordingly, when replacing the filter (120), the front panel (112) can be opened, and the filter (120) can be removed from the filter bracket (130) or installed on the filter bracket (130).

[0077] The bottom of the front panel (112) may be spaced apart from the floor surface on which the water purification device body (100) is placed. Additionally, the user may insert their hand into the space between the front panel (112) and the floor surface to separate the front panel (112).

[0078] And, the purified water that has passed through the filter (120) can be supplied to the user through the water outlet nozzle (300). A purified water flow path may be arranged inside the main body (100) of the water purification device to guide the purified water that has passed through the filter toward the water outlet nozzle (300).

[0079] In addition, purified water that has passed through the filter can be supplied to the outlet nozzle (300) in the form of cold water or hot water after being cooled or heated.

[0080] To this end, a hot water tank for heating purified water that has passed through the filter and a hot water flow path for guiding the hot water heated in the hot water tank toward the outlet nozzle (300) may be arranged inside the main body (100) of the water purification device. For example, the hot water tank can generate hot water by instantly heating the purified water passing through the hot water tank using an induction heating (IH) method.

[0081] In addition, the above-mentioned hot water tank may be equipped with a thermoelectric element or a heating wire to heat the purified water passing through the hot water tank into hot water.

[0082] In addition, instead of the above-mentioned induction heating method, various heating methods may be applied within the range where purified water passing through the hot water tank can be heated into hot water.

[0083] Additionally, a cooling tank for cooling the purified water that has passed through the filter and a cold water flow path for guiding the cold water cooled in the cooling tank to the outlet nozzle (300) may be arranged inside the main body (100) of the water purification device. For example, the cooling tank may be equipped with a compressor, an evaporator, a condenser, a cooling fan, etc., to cool the purified water passing through the cooling tank into cold water. Additionally, the cooling tank may be equipped with a thermoelectric element to cool the purified water passing through the cooling tank into cold water.

[0084] In addition, various cooling devices may be applied in place of the above evaporator, within the range where the purified water passing through the cooling tank can be cooled into cold water.

FIG. 4 is a drawing showing the filter being fixed by lowering the fixing means while the filter is mounted on the filter bracket. FIG. 5 is a longitudinal cross-sectional view showing one embodiment of the fixing means. FIG. 6 is a longitudinal cross-sectional view showing another embodiment of the fixing means. FIG. 7 is a front view showing the filter mounted on the filter bracket. FIG. 8 is a side view showing the filter mounted on the filter bracket. FIG. 9 is a front view showing the filter cap and the filter head combined. FIG. 10 is a perspective view showing the fixing means separated. FIG. 11 is a perspective view showing the filter head separated. FIG. 12 is a perspective view showing the filter bracket separated.

[0086] Referring to FIGS. 3 to 12, the water purification device of the present invention comprises a filter body (121), a filter head (122) provided at the top of the filter body (121), and a filter bracket (130) to which the filter head (122) is coupled and which is connected to a water supply channel into which raw water flows.

[0087] Various filtration means are accommodated inside the filter body (121) above.

[0088] For example, the interior of the filter body (121) may accommodate a carbon block, a hollow fiber membrane filter, an electrostatic adsorption material, an ion exchange resin, etc.

[0089] Generally, water introduced into the upper part of the filter body (121) flows downward and then flows from the lower part to the upper part, is filtered, and can be discharged through the upper part of the filter body (121).

[0090] And, a filter head (122) is attached to the top of the filter body (121).

[0091] The filter head (122) includes an inlet pipe (1221) that extends horizontally to allow water to flow in, and an outlet pipe (1222) that extends horizontally parallel to the inlet pipe (1221) to allow water to be discharged.

[0092] The inlet pipe (1221) and the outlet pipe (1222) may be extended parallel to each other in the same direction. For example, the inlet pipe (1221) and the outlet pipe (1222) may be extended to the rear in order to be connected at the front of the filter bracket (130).

[0093] The filter bracket (130) comprises a first groove (1321) formed horizontally so that the inlet pipe (1221) is inserted horizontally, and a second groove (1322) extended horizontally so that the discharge pipe (1222) is inserted horizontally, so that the filter head (122) can be connected to or separated from the filter bracket (130) in a horizontal direction.

[0094] In detail, the filter head (122) can be coupled to the filter bracket (130) while moving horizontally from the front to the rear of the water purification device.

[0095] Additionally, the filter head (122) may be separated from the filter bracket (130) as it moves horizontally from the rear to the front of the water purification device.

[0096] Additionally, a barrier wall (1323) may be formed between the first groove (1321) and the second groove (1322) to partition the first groove (1321) and the second groove (1322).

[0097] By the above barrier wall (1323), the distance between the first groove (1321) and the second groove (1322) can be secured, and the first groove (1321) and the second groove (1322) can be partitioned.

[0098] Additionally, the filter bracket (130) is extended in the left-right direction and includes a main channel (1331) into which raw water flows in on one side and purified water is discharged on the other side, and the first groove (1321) and the second groove (1322) are extended in the front-back direction, so that water flowing into one side of the main channel (1331) flows into the filter body (121) through the first groove (1321) and the inlet pipe (1221), and purified water discharged from the filter body (121) can be discharged to the other side of the main channel (1331) through the discharge pipe (1222) and the second groove (1322).

[0099] Additionally, the filter bracket (130) may further include an inlet channel (1332) that extends in the up-down or front-back direction and is connected to one side of the main channel (1331) to allow raw water to flow in, and an outlet channel (1333) that extends in the up-down or front-back direction and is connected to the other side of the main channel (1331) to allow purified water to be discharged.

[0100] Raw water flows in from the upper side to the lower side or from the rear to the front through the inlet channel (1332). Then, the raw water flows through the main channel (1331) and flows into the filter body (121) through the first groove (1321) and the inlet pipe (1221).

[0101] And, it is filtered into purified water while passing through the inside of the filter body (121).

[0102] And, the purified water discharged to the outside of the filter body (121) is discharged to the other side of the main flow path (1331) through the discharge pipe (1222) and the second groove (1322), and then finally discharged to the outlet flow path (1333) connected to the other side of the main flow path (1331).

[0103] And, through the above-mentioned discharge channel (1333), purified water is discharged from the lower side to the upper side or from the front to the rear.

[0104] Additionally, the main channel (1331) has one or both ends open, and a plug (134) can be fitted into the opening (1331a) of the one or both ends of the main channel (1331) to block it.

[0105] A first step portion is formed on the inner surface of one or both ends of the open main channel (1331), and a second step portion (1341) corresponding to the first step portion may be formed on the plug portion (134).

[0106] The plug portion (134) is fitted into the open ends of the main Euro (1331) above.

[0107] And, the first step portion and the second step portion come into contact with each other. And, a sealing member (1342), such as an O-ring, can be fitted between the first step portion and the second step portion.

[0108] And, an extension of the plug portion (134) formed by the second step portion can be inserted and fixed into the inner hole of the main passage (1331) formed by the first step portion.

[0109] The filter bracket (130) includes a first filter bracket (130a) and a second filter bracket (130b) connected to one side of the first filter bracket (130), and the length of the filter bracket (130) can be adjusted according to the number of filters (120).

[0110] That is, the filter bracket (130) may be used as a single unit, or two or more may be extended horizontally and used as multiple units.

[0111] And, as described above, when the first filter bracket (130a) and the second filter bracket (130b) are connected, a clip (139) can be fitted into the connection portion of the first filter bracket (130a) and the second filter bracket (130b).

[0112] The clip (139) may be provided to secure the first filter bracket (130a) and the other end of the second filter bracket (130b) by simultaneously gripping them.

[0113] In addition, as described above, when multiple filter brackets are connected, one end of the second filter bracket (130b) is connected to one end of the first filter bracket (130a) in such a manner that one end of the second filter bracket (130b) is inserted therein, so that the flow path of the first filter bracket (130a) and the flow path of the second filter bracket (130b) can be connected.

[0114] Additionally, the filter bracket (130) forms an extension wall (135) that extends downward, and the extension wall (135) is fixed to the main body of the water purification device.

[0115] The extension wall (135) may be provided in the form of a flat plate and may be fixed to the inner surface of the water purification device body through various fastening means while in contact with the inner surface of the water purification device body.

[0116] In the extension wall (135), a rearwardly concave fastening groove (1352) is formed at the location where the fastening means is to be fastened, and a fastening hole (1351) may be formed in the fastening groove (1352).

[0117] Additionally, the filter bracket (130) includes a fixing means (136) that is rotatably installed on the filter bracket (130) and selectively fixes the filter head (122) while rotating around the extended direction of the filter bracket (130).

[0118] The above fixing means (136) has one side open and at least a portion may be formed in an arc shape.

[0119] The above fixing means (136) can have both ends rotatably connected to both sides of the filter bracket (130).

[0120] The above fixing means (136) can rotate upward to release the fixing of the filter head (122) while it is in a vertically upright position.

[0121] Additionally, the fixing means (136) can rotate forward to fix the filter head (122) in a position parallel to the horizontal direction.

[0122] The filter head (122) includes a side portion (1223) that is formed convexly forward so as to restrict movement by the fixing means (136) while in contact with at least a part of the fixing means (136) when the fixing means (136) is rotated forward.

[0123] Additionally, at the bottom of the fixing means (136), a gripping portion (1363) extending outward is formed to facilitate gripping of the fixing means (136).

[0124] Accordingly, the user can grasp the gripping portion (1363) that protrudes outward and extends along the lower circumference of the fixing means (136), and rotate the fixing means (136).

[0125] The above fixing means (136) may have a semicircular shape in which at least a portion is convex toward the front when rotated forward.

[0126] Additionally, on one side of the first protrusion (1321a) defining the first groove (1321) and on the other side of the second protrusion (1322a) defining the second groove (1322), an axial portion (1321b, 1322b) extending outward is formed, and both ends of the fixing means (136) are rotatably coupled to the axial portion (1321b, 1322b).

[0127] Both ends of the above-mentioned fixing means (136) may each have a recessed shaft groove (1364) formed on a surface facing each other so that the shaft portion (1321b, 1322b) can be fitted therein.

[0128] Additionally, at both ends of the fixing means (136), a stopper (1362) protruding may be formed to restrict the rotation of the fixing means (136) while contacting the filter bracket (130) when the fixing means (136) is rotated upward.

[0129] Additionally, the two ends of the fixing means (136) may form an inwardly convex and downwardly extended extension rib (1366) on the surfaces facing each other.

[0130] The above extension rib (1366) is formed below the shaft groove (1364).

[0131] The extension rib (1366) may be formed to push at least a portion of the filter head (122) forward when the fixing means (136) is rotated upward.

[0132] When the extension rib (1366) is formed as described above, the filter head (122) is pushed forward by simply rotating the fixing means (136) upward, and the filter head (122) can be separated from the filter bracket (130).

[0133] Additionally, the above fixing means (136) may have a pressing part (1367) in the shape of an inclined or curved surface formed on the inner side of the front.

[0134] The above pressing part (1367) may be formed to push at least a portion of the filter head (122) backward when the above fixing means (136) is rotated forward.

[0135] When the pressing part (1367) is formed as described above, the filter head (122) is pushed backward by simply rotating the fixing means (136) forward, and the filter head (122) can be coupled to the filter bracket (130).

[0136] Additionally, an externally protruding locking rib (1368) may be additionally formed on the upper part of the extension rib (1366).

[0137] The above-mentioned catch rib (1368) may be formed with at least a portion being flat.

[0138] When the above-mentioned catch rib (1368) is formed, the catch rib (1368) engages with the filter head (122) when the filter head (122) is coupled to the filter bracket (130) while rotating the fixing means (136) forward. The user can recognize this and rotate the fixing means (136) forward with greater force to securely couple the filter head (122) to the filter bracket (130). Furthermore, as the filter head (122) is coupled to the filter bracket (130) with greater force due to the configuration of the catch rib (1368), the gap between the parts is reduced.

[0139] Additionally, a locking projection (1224) protruding forward is formed on the front surface of the filter head (122), and a locking groove (1361) into which the locking projection (1224) is fitted is formed on the inner surface of the fixing means (136) when the fixing means (136) is rotated forward.

[0140] Additionally, a locking projection (1362) protruding outward from the inner side of the fixing means (136) may be formed at the upper end of the locking groove (1361).

[0141] At this time, the above-mentioned locking projection (1224) is fitted into the locking groove (1361), allowing the fixing means (136) to fix the filter head (122) more securely, and the lower end of the locking projection (1362) is placed over the upper end of the locking projection (1224), thereby restricting the rotation of the fixing means (136).

[0142] Additionally, on both ends of the filter head (122), a pressing projection (1227) protruding outward may be formed.

[0143] Additionally, the filter bracket (130) may have a horizontally open pressing groove (138) formed so that the pressing projection (1227) can be fitted into it.

[0144] As described above, when the pressing projection (1227) is fitted into the pressing groove (138), the fastening force between the filter head (122) and the filter bracket (130) can be further improved.

[0145] Additionally, the filter body (121) includes a filter cap (123) that is coupled to the filter head (122) at the top, and a protrusion (1231) is formed on the filter cap (123), and an opening (1225) is formed on the filter head (122) to allow the protrusion (1231) to be viewed from the outside.

[0146] The above protrusion (1231) can form an inclined surface (1231a) on one side or the other side.

[0147] One side of the opening (1225) is connected to one side of a rib (1226) that is elastically deformed and engaged with one side of the projection (1231). The rib (1226) may be formed to have a convex shape toward the inside of the filter head (122).

[0148] Accordingly, when the filter cap (123) is inserted into the filter head (122) while the filter body (121) and the filter cap (123) are combined, the user can check the situation of the filter cap (123) being combined through the opening (1225), and when the rib (1226) presses the protrusion (1231) and the one end of the rib (1226) (the right end in Fig. 13) catches on the one end of the protrusion (1231) (the left end in Fig. 13), the user can recognize that the filter cap (123) is properly combined with the filter head (122).

[0149] FIG. 13 is a perspective view of a filter socket. FIG. 14 is an exploded perspective view of a filter head and a filter bracket. FIG. 15 is a drawing showing the water flow path in the filter bracket.

[0150] Referring to FIGS. 13 to 15, the filter bracket (130) of the present invention further includes a filter socket (137).

[0151] The filter socket (137) can be positioned between the filter bracket (130) and the filter head (122).

[0152] The filter socket (137) can form a third groove (1371) and a fourth groove (1372) at positions corresponding to the first groove (1321) and the second groove (1322) of the filter bracket (130), respectively.

[0153] And, the filter socket (137) forms a first extension (1373) and a second extension (1374) protruding forward to define a third groove (1371) and a fourth groove (1372), respectively.

[0154] The first extension part (1373) and the second extension part (1374) can form a hollow cylinder.

[0155] The first extension part (1373) and the second extension part (1374) can each form a first opening (1373a) and a second opening (1374a) that are open toward the outside on the outer surface.

[0156] The first opening (1373a) and the second opening (1374a) are open in a horizontal direction, and a pressing projection (1227) protruding outwardly from both ends of the filter head (122) can be inserted.

[0157] A third opening (1375) may be formed between the first extension (1373) and the second extension (1374).

[0158] The third opening (1375) is formed so that the third groove (1371) and the fourth groove (1372) are connected.

[0159] Additionally, the filter socket (137) may further include a third extension and a fourth extension protruding rearward from the circumference of the third groove (1371) and the fourth groove (1372), and the third extension and the fourth extension may be fitted into the first groove (1321) and the second groove (1322) of the filter bracket (130), respectively.

[0160] Accordingly, the third groove (1371) and the fourth groove (1372) of the filter socket (137) can communicate with the first groove (1321) and the second groove (1322) of the filter bracket (130), respectively.

[0161] Additionally, a ring-shaped connecting member (1336) is disposed between the third groove (1371) and the fourth groove (1372) of the filter socket (137) and the first groove (1321) and the second groove (1322) of the filter bracket (130), respectively, and through the connecting member (1336), the third groove (1371) and the fourth groove (1372) may be connected to the first groove (1321) and the second groove (1322), respectively.

[0162] The filter socket (137) can be extended rearward at the top and then form an upper fastening portion (1376) that extends upward.

[0163] And, the filter socket (137) can be extended rearward at the bottom and then form a lower fastening part (1377) that is extended downward.

[0164] Additionally, the filter bracket (130) may form an upper fastening hole (1337) on the upper side of the main channel (1331) so that the upper fastening part (1376) of the filter socket (137) is fitted therein. Additionally, the filter bracket (130) may form a lower fastening hole (1335) on the lower side of the main channel (1331) so that the lower fastening part (1334) of the filter socket (137) is fitted therein.

[0165] FIG. 16 is a perspective view from above showing a filter head coupled to a filter socket. FIG. 17 is a perspective view from above showing a filter head. FIG. 18 is a perspective view from above showing a fixing means. FIG. 19 is a cross-sectional view illustrating one example of the fixing means pushing out the filter head while rotating. FIG. 20 is a cross-sectional view illustrating another example of the fixing means pushing out the filter head while rotating.

[0166] Referring to FIGS. 16 to 20, the filter bracket (130) may include an inlet channel (1332) through which raw water flows in and an outlet channel (1333) through which purified water is discharged.

[0167] The above inlet channel (1332) and outlet channel (1333) can be extended in the front and rear directions.

[0168] The above inlet channel (1332) and outlet channel (1333) can each be extended in the same direction as the inlet pipe (1221) and outlet pipe (1222) of the filter head (122).

[0169] Accordingly, water flowing into the inlet channel (1332) flows into the inlet pipe (1221), and water discharged through the outlet pipe (1222) can flow into the outlet channel (1333).

[0170] In addition, the filter bracket (130) has a first groove and a second groove formed therein into which the inlet pipe (1221) and the outlet pipe (1222) of the filter head (122) are fitted, and the inlet water passage (1332) is formed to be in communication with the first groove and the outlet water passage (1333) is formed to be in communication with the second groove.

[0171] Accordingly, water flowing into the inlet channel (1332) can flow into the inlet pipe (1221) fitted into the first groove, and water discharged into the discharge pipe (1222) fitted into the second groove can flow into the discharge channel (1333).

[0172] For example, the inlet channel (1332) and the outlet channel (1333) may be extended to the rear (left side in FIG. 16) of the body portion (131) of the filter bracket (130), and the first groove portion and the second groove portion may be formed to be open to the front (right side in FIG. 16) of the body portion (131) of the filter bracket (130).

[0173] And, as the inlet pipe (1221) and the outlet pipe (1222) move from the front to the rear, they are fitted into the first groove and the second groove, respectively, so that the flow path of the filter bracket (130) and the flow path of the filter head (122) can be connected.

[0174] For reference, an inlet pipe (1338) and an outlet pipe (1339) may be formed respectively on the front (right side in FIG. 16) based on the body portion (131) of the filter bracket (130) to define the first groove and the second groove.

[0175] A flow path may be formed on the inner side of the body part (131) to connect the inlet flow path (1332) to the inlet pipe (1338) and to connect the outlet flow path (1333) to the outlet pipe (1339).

[0176] The water passage connecting the inlet passage (1332) to the inlet pipe (1338) and the water passage connecting the outlet passage (1333) to the outlet pipe (1339) may be formed in a straight line or bent.

[0177] The axial center of the inlet channel (1332) and the axial center of the inlet pipe (1338) may be arranged coaxially or offset from each other.

[0178] Additionally, the axial center of the above-mentioned water outlet channel (1333) and the axial center of the above-mentioned water outlet pipe (1339) may be arranged coaxially or offset from each other.

[0179] In addition, as described above, the inlet pipe (1221) and the outlet pipe (1222) move from the front to the rear and are fitted into the first groove and the second groove, respectively, and a fixing means (136) is provided to maintain a state in which the flow path of the filter bracket (130) and the flow path of the filter head (122) are connected to each other.

[0180] The above fixing means (136) is rotatably installed on the filter bracket (130) and selectively fixes the filter head (122) while rotating around a rotation axis extended in the left-right direction (up-down direction based on FIG. 16).

[0181] The above fixing means (136) has one side open and at least a portion may be formed in an arc shape.

[0182] The above fixing means (136) can have both ends rotatably connected to both sides of the filter bracket (130).

[0183] The above fixing means (136) can rotate upward to release the fixing of the filter head (122) while it is in a vertically upright position.

[0184] Additionally, the fixing means (136) can be rotated forward of the filter head (122) to fix the filter head (122) in a position parallel to the horizontal direction.

[0185] The filter head (122) includes a side portion (1223) that is formed convexly forward so as to restrict movement by the fixing means (136) while in contact with at least a part of the fixing means (136) when the fixing means (136) is rotated forward.

[0186] Additionally, at the bottom of the fixing means (136), a gripping portion (1363) extending outward is formed to facilitate gripping of the fixing means (136).

[0187] The above gripping portion (1363) may extend along the circumference of the lower end of the fixing means (136).

[0188] The above gripping portion (1363) may be formed around the entire circumference of the lower end of the fixing means (136) or only in a portion of the section.

[0189] Accordingly, the user can grasp the gripping portion (1363) that protrudes outward and extends along the lower circumference of the fixing means (136), and rotate the fixing means (136).

[0190] The above fixing means (136) may have a semicircular shape in which at least a portion is convex toward the front when rotated forward.

[0191] Additionally, on both sides of the body portion (131) of the filter bracket (130), an axial portion (1311) extending outward is formed, and both ends of the fixing means (136) are rotatably connected to the axial portion (1311).

[0192] Both ends of the above-mentioned fixing means (136) may each have a recessed shaft groove (1364) formed on a surface facing each other so that the shaft portion (1311) can be fitted therein.

[0193] The above fixing means (136) each forms a front portion (136) that is convexly formed forward in an arch shape, and a pair of side portions (136b) that extend backward from both sides of the front portion (136a).

[0194] And, on the inner surface of the side portion (136b), the shaft groove (1364) may be formed on the mutually facing surfaces.

[0195] On the inner surface of the above-mentioned side portion (136b), an inwardly protruding shaft projection (136c) is formed on the mutually facing surface, and the shaft groove (1364) can be formed in the shaft projection (136c).

[0196] The above-mentioned shaft groove (1364) can be formed with an auxiliary projection (1364a) that extends in the longitudinal direction (left and right direction based on FIG. 18) on the inner surface and protrudes inward.

[0197] The above auxiliary projection (1364a) can fix the shaft portion (1311) fitted into the shaft groove (1364).

[0198] The above auxiliary projection (1364a) can limit the rotation range of the fixing means (136) or form resistance only within a specific rotation range when the fixing means (136) rotates while the shaft portion (1311) is fitted into the shaft groove (1364).

[0199] The above fixing means (136) can form upper surface portions (136d, 136e) that extend inward from the top of the front portion (136a) and the side portion (136b).

[0200] And, the upper surface portions (136d, 136e) come into contact with the top of the filter head (122) when the fixing means (136) fixes the filter head (122) in a horizontal position, and the rotational movement of the fixing means (136) may be restricted.

[0201] Additionally, at both ends of the fixing means (136), a stopper (1362) protruding may be formed to restrict the rotation of the fixing means (136) while contacting the filter bracket (130) when the fixing means (136) is rotated upward.

[0202] The stopper (1362) may be formed to extend outward from the outer surface of the shaft projection (136c).

[0203] In addition, the body portion (131) of the filter bracket (130) may form a locking portion (1312) protruding outwardly on both sides.

[0204] The above-mentioned locking portion (1312) may be formed further back (left side according to FIG. 16) than the above-mentioned shaft portion (1311).

[0205] The above-mentioned catch portion (1312) may include a horizontal portion formed to extend in the front-rear direction, thereby forming an overall '—' shape.

[0206] In addition, the above-mentioned catch portion (1312) may include a horizontal portion formed to extend in the front-rear direction and a vertical portion extending upward from the rear end of the horizontal portion, thereby forming an overall 'L' shape.

[0207] When the fixing means (136) rotates in a vertical direction to open the filter head (122) from a horizontal direction to fix the filter head (122), and the fixing means (136) rotates sufficiently so that the fixing of the filter head (122) can be released, the stopper (1362) is caught on the upper surface of the catch (1312), and the rotation of the fixing means (136) can be restricted.

[0208] Additionally, on the outer surface of the shaft projection (136c), at least one auxiliary stopper (1362a) can be formed that contacts the locking part (1312) when the fixing means (136) rotates in a vertical direction to open the filter head (122) from a horizontal direction to fix the filter head (122).

[0209] The above auxiliary stopper (1362a) may be formed at the rear lower end (lower left end in Fig. 19) of the above stopper (1362).

[0210] Two auxiliary stoppers (1362a) are formed and can be spaced apart in the circumferential direction of the shaft projection (136c).

[0211] The above auxiliary stopper (1362a) may protrude shorter than the stopper (1362).

[0212] The above auxiliary stopper (1362a) catches on or contacts the locking part (1312) when the fixing means (136) rotates, but can pass through the locking part (1312) when the user rotates the fixing means (136) with force.

[0213] The end of the auxiliary stopper (1362a) that contacts the catch portion (1312) may be formed as a curved or inclined surface.

[0214] When the above fixing means (136) rotates in a vertical direction to open the filter head (122) from a horizontal direction to fix the filter head (122), the user can recognize the rotational position of the fixing means (136) as the auxiliary stopper (1362a) comes into contact with the locking part (1312).

[0215] And, when the fixing means (136) rotates sufficiently so that the fixing of the filter head (122) can be released, the stopper (1362) is caught on the upper surface of the catch (1312), and the rotation of the fixing means (136) can be restricted.

[0216] Additionally, the two ends of the fixing means (136) may form an inwardly convex and downwardly extended extension rib (1366) on the surfaces facing each other.

[0217] The above extension rib (1366) is formed below the shaft groove (1364).

[0218] The above extension rib (1366) may extend from the outer surface of the above shaft projection (136c).

[0219] The above extension rib (1366) may extend from the lower front (lower right side in Fig. 19) of the stopper (1362).

[0220] The extension rib (1366) may be formed to push at least a portion of the filter head (122) forward when the fixing means (136) is rotated upward.

[0221] When the extension rib (1366) is formed as described above, the filter head (122) is pushed forward by simply rotating the fixing means (136) upward, and the filter head (122) can be separated from the filter bracket (130).

[0222] Additionally, the above fixing means (136) may have a pressing part (1367) in the shape of an inclined or curved surface formed on the inner side of the front.

[0223] The above pressing portion (1367) may be formed to push backward while pressing the inclined or curved edge portion (122e) formed between the upper surface and the front surface of the filter head (122) and the front surface (1223) of the filter head (122) when the above fixing means (136) is rotated forward.

[0224] When the pressing part (1367) is formed as described above, the filter head (122) is pushed backward by simply rotating the fixing means (136) forward, and the filter head (122) can be coupled to the filter bracket (130).

[0225] Additionally, an externally protruding locking rib (1368) may be additionally formed on the upper part of the extension rib (1366).

[0226] The above-mentioned catch rib (1368) may be formed with at least a portion being flat.

[0227] The above-mentioned catch rib (1368) protrudes from the upper surface of the above-mentioned extension rib (1368), and both sides are formed at an angle to form an inclined surface (1368a, 1368b).

[0228] The above-mentioned catch rib (1368) can be formed so that its cross-sectional area decreases as it extends upward.

[0229] The above-mentioned catch rib (1368) may be formed as a curved surface.

[0230] When the above-mentioned catch rib (1368) is formed, the catch rib (1368) engages with the filter head (122) when the filter head (122) is coupled to the filter bracket (130) while rotating the fixing means (136) forward. The user can recognize this and rotate the fixing means (136) forward with greater force to securely couple the filter head (122) to the filter bracket (130). Furthermore, as the filter head (122) is coupled to the filter bracket (130) with greater force due to the configuration of the catch rib (1368), the gap between the parts is reduced.

[0231] Additionally, on both ends of the filter head (122), a pressing projection (1227) protruding outward may be formed.

[0232] The above pressing projection (1227) can form an upper groove (1227b) that is concavely formed inwardly on the upper surface.

[0233] Additionally, the above-mentioned pressing projection (1227) can form an inclined surface (1227a) on the corner portion of one lower side (left lower side in Fig. 17).

[0234] The above-mentioned pressing projection (1227) may be formed to be pushed forward when the locking rib (1368) rotates while in contact with the above-mentioned locking rib (1368).

[0235] Referring to FIG. 18, when the fixing means (136) is rotated horizontally to fix the filter head (122), the pressing projection (1227) is in contact with the upper surface or inclined surface (1227a) of the catch rib (1368) and may be positioned lower than the upper surface (136e).

[0236] When the above fixing means (136) rotates horizontally to fix the filter head (122), the pressing projection (1227) may be positioned above the locking rib (1368) so as not to be in contact with the locking rib (1368).

[0237] When the fixing means (136) is rotated horizontally to fix the filter head (122), the pressing projection (1227) is positioned above the catch rib (1368) and below the upper surface (136e), and may be in a non-contact state with the catch rib (1368).

[0238] With the fixing means (136) rotated horizontally to fix the filter head (122), the pressing projection (1227) can be formed at a height similar to that of the shaft portion (1311).

[0239] The above inclined surface (1227a) may come into contact with the extension rib (1366) or the catch rib (1368).

[0240] Meanwhile, the above-mentioned catch rib (1368) may be formed at a position adjacent to the above-mentioned shaft projection (136c).

[0241] The above-mentioned catch rib (1368) can be formed with a predetermined distance from the above-mentioned shaft projection (136c).

[0242] As shown in FIG. 20, the extension rib (1366) forms a first section (1366a) extending from the shaft projection (136c), and the catch rib (1368) may be formed in a section after the first section (1366a).

[0243] As shown in FIG. 19, the catch rib (1368) may be formed at the starting point where the extension rib (1366) extends from the shaft projection (136c), without having a separate first section (1366a).

[0244] Referring to FIG. 19 (a), the fixing means (136) fixes the filter head (122) in a horizontal position.

[0245] And, in this state, the fixing means (136) is in a state where it presses the filter head (122) and pushes it backward (to the left according to FIG. 19), and thus, the filter head (122) can maintain the state of being coupled to the filter bracket (130).

[0246] And, the above-mentioned catch rib (1368) and press projection (1227) may be in a non-contact state, or at least partially in contact state.

[0247] Referring to FIG. 19(b), the fixing means (136) is rotated from a horizontal position to a vertical position (counterclockwise with respect to FIG. 19). When the fixing means (136) is rotated as described above, the extension rib (1366) rotates and the locking rib (1368) pushes the pressing projection (1227) forward (to the right with respect to FIG. 19).

[0248] At this time, since the above-mentioned locking rib (1368) is formed at the starting point where the extension rib (1366) extends from the shaft projection (136c) without having a separate first section (1366a), the above-mentioned upper fixing means (136) can rotate from a horizontal position to a vertical direction (counterclockwise according to FIG. 19) at the same time the locking rib (1368) can push the pressing projection (1227) forward (to the right according to FIG. 19).

[0249] And, the filter head (122) with the pressing projection (1227) formed thereon is pushed forward (to the right according to FIG. 19), and the filter head (122) can be separated from the filter bracket (130).

[0250] That is, the filter (120) can be separated from the filter bracket (130).

[0251] Referring to FIG. 20 (a), the fixing means (136) fixes the filter head (122) in a horizontal position.

[0252] And, in this state, the fixing means (136) is in a state where it presses the filter head (122) and pushes it backward (to the left according to FIG. 20), and thus the filter head (122) can maintain the state of being coupled to the filter bracket (130).

[0253] And, the above-mentioned catch rib (1368) and press projection (1227) may be in a non-contact state.

[0254] Referring to FIG. 20(b), the fixing means (136) is in a state where it has been rotated first by a first angle in the vertical direction (counterclockwise with respect to FIG. 20) from a horizontal position. When the fixing means (136) is rotated first by a first angle as described above, the extension rib (1366) rotates and the locking rib (1368) comes into contact with the pressing projection (1227).

[0255] Referring to (c) of FIG. 20, the fixing means (136) is in a state where it has been rotated a second time by a second angle greater than the first angle in the vertical direction (counterclockwise with respect to FIG. 20). When the fixing means (136) is rotated a second time by the second angle as described above, the extension rib (1366) rotates and the locking rib (1368) pushes the pressing projection (1227) forward (to the right with respect to FIG. 20).

[0256] For example, when the fixing means (136) rotates about 30° or more in a vertical direction (counterclockwise according to FIG. 20) from a horizontal position, the position of the locking rib (1368) can be formed so that the locking rib (1368) pushes the pressing projection (1227) forward (to the right according to FIG. 20).

[0257] In this embodiment, the extension rib (1366) forms a first section (1366a) extending from the shaft projection (136c), and the catch rib (1368) may be formed in a section after the first section (1366a).

[0258] Therefore, even if the upper fixing means (136) rotates from a horizontal position to a vertical direction (counterclockwise according to FIG. 20), the locking rib (1368) cannot push out the pressing projection (1227) during the first rotation section, and from the position past the first rotation section, the locking rib (1368) can push the pressing projection (1227) forward (to the right according to FIG. 20).

[0259] And, the filter head (122) with the pressing projection (1227) formed thereon is pushed forward (to the right according to FIG. 20), and the filter head (122) can be separated from the filter bracket (130).

[0260] That is, the filter (120) can be separated from the filter bracket (130).

[0261] As described above, when the catch rib (1368) is formed in the section after the first section (1366a) of the pressing projection (1227), the catch rib (1368) does not immediately push out the pressing projection (1227) even if the fixing means (136) rotates from a horizontal position to a vertical direction.

[0262] That is, in the first rotation section, the locking rib (1368) does not push out the pressing projection (1227), and the filter head (122) can remain connected to the filter bracket (130).

[0263] Therefore, even if the fixing means (136) is lifted upward by a fine physical force without the intention of separating the filter from the filter bracket, the filter head (122) remains connected to the filter bracket (130), and no leakage occurs.

[0264] In the case of the present invention, the intention to separate the filter head (122) is clear, so the position of the catch rib (1368) is formed so that the filter head (122) can be separated from the filter bracket (130) only when the fixing means (136) is lifted while rotating it by more than a first angle (for example, more than 30°).

[0265] On the other hand, even if the fixing means (136) is lifted up, the filter head (122) is not immediately separated from the filter bracket (130) but remains connected, so that leakage caused by the filter head being separated from the filter bracket in an unintended state can be prevented.
