Description

water purifier

[0001] The present disclosure relates to a water purifier.

[0002] As technology advances, various types of water purifiers have been developed to remove foreign substances or harmful substances contained in raw water and provide potable water.

[0003] Water purifiers not only purify raw water using a filter, but can also control the temperature of the purified water to provide it to users as cold or hot water. The hot water can be used to heat food or brew tea or coffee, depending on the intended use.

[0004] In particular, coffee made by passing hot water through coffee grounds to brew coffee is also called drip coffee. When making drip coffee, it is important that the hot water is evenly distributed through the coffee grounds and filtered slowly.

[0005] However, the water outlet of conventional water purifiers has mainly been a single cylindrical shape, which has caused a problem in that hot water is only dispensed from one point when making beverages such as drip coffee.

[0006] According to at least one embodiment of the present disclosure, the water purifier may include a water purification unit and a water discharge unit connected to the water purification unit.

[0007] The above-mentioned discharge unit may include a discharge pipe and a guide coupled to one end of the discharge pipe.

[0008] The above guide may include a case, a rotating part arranged rotatably on the inside of the case, and a guide pipe having a guide path formed therein that extends from the center of the case toward one side of the case to supply water to one area of ​​the rotating part.

[0009] The above case may include an upper case facing one end of the outlet pipe and a lower case coupled to the lower side of the upper case.

[0010] The above rotating part may include a plurality of rotating blades arranged in a circumferential direction from the center of the case so as to rotate upon colliding with water passing through the guide passage.

[0011] The above guide may include a nozzle portion arranged to rotate together with the rotating portion.

[0012] The above nozzle part can be placed on the lower side of the rotating part.

[0013] The above guide may further include a cover coupled to the lower side of the nozzle portion.

[0014] The above nozzle part may include a plurality of outlet holes formed to penetrate the lower surface of the nozzle part perpendicular to the ground.

[0015] The above lower case may include multiple outlet holes.

[0016] The above plurality of outlet holes may include vertical outlet holes formed to penetrate the lower surface of the lower case perpendicular to the ground.

[0017] The above plurality of outlet holes may further include a side outlet hole formed to penetrate a connecting surface connecting the lower surface of the lower case and the side surface of the lower case.

[0039] Below, water purifiers according to various embodiments are specifically described with reference to the attached drawings.

[0040] FIG. 1 is a drawing for explaining a water purifier according to one embodiment of the present disclosure. Referring to FIG. 1, the water purifier (1) may include a water purification unit (10) and a water discharge unit (20).

[0041] Water purifiers (1) can be classified into various types according to their purpose or arrangement. Among them, the classification according to the arrangement type can be broadly divided into countertop water purifiers and under-sink water purifiers. The countertop water purifier is a type in which the water purification unit (10) and the water outlet unit (20) are arranged together on the upper part of the work surface (2). Conversely, the under-sink water purifier is a type in which the water purification unit (10) is arranged in the lower space of the work surface (2). In the case of the under-sink water purifier, the water outlet unit (20) can be located on the upper part of the work surface (2) for easy access for the convenience of the user. In addition, the water purifier (1) can have various types depending on the arrangement location, but in this drawing, a water purifier (1) in which the water purification unit (10) is arranged on the lower part of the work surface (2) and the water outlet unit (20) is arranged on the upper part of the work surface (2) will be described.

[0042] The water purification unit (10) is configured to purify raw water supplied from an external water source (3). The water purification unit (10) may include a filter unit (11) and a heat exchange unit (12).

[0043] The raw water can flow from the external water source (3) to the water purifier (1) side through an external water supply pipe (100) connecting the external water source (3) and the water purifier (1).

[0044] The filter unit (11) may include at least one filter. The filter is configured to remove foreign substances and harmful substances contained in the raw water. The filter may be a specific filter among a carbon filter, a ceramic filter, a reverse osmosis filter (RO filter, ReverS1e oS1moS1iS1 filter), a UV filter, a mineral filter, an ion exchange resin filter, and a nano filter, but the types of filters are not limited thereto.

[0045] Accordingly, water supplied from an external water source (3) to a water purification unit (10) can be purified into drinkable water quality through the filter of the filter unit (11).

[0046] The heat exchange unit (12) is configured to cool or heat the purified water in the water purification unit (10). The heat exchange unit (12) may include a rapid heater (121). The rapid heater (121) is configured to heat the water to a desired temperature while the purified water passes through the space between the wound coils by applying heat to the wound coils. In addition, although not specifically illustrated in the drawing, the heat exchange unit (12) may further include a cooling device including a compressor, a condenser, an expansion valve, and an evaporator.

[0047] Accordingly, the purified water in the purification unit (10) can be cooled or heated while passing through the heat exchange unit (12).

[0048] The water outlet unit (20) may be called a faucet and is configured to supply water purified in the water purification unit (10) and cooled or heated to the user. The water outlet unit (20) may be connected to the water purification unit (10) by an internal water supply pipe (200).

[0049] The length and arrangement position of the internal water supply pipe (200) are not limited to those shown, and may be determined differently during the process of installing the water purifier (1). For example, in the case of a water purifier (1) in which the water purification unit (10) and the water outlet unit (20) are spaced apart from each other at the bottom and top of the work table (2), the internal water supply pipe (200) may be provided to penetrate one side of the work table (2) and connect the water purification unit (10) and the water outlet unit (20). In contrast, in the case of a countertop water purifier in which the water purification unit (10) and the water outlet unit (20) are arranged adjacently in a space where the lower space of the work table (2) is insufficient or where the work table (2) does not exist, the internal water supply pipe (200) may be provided to connect the water purification unit (10) and the water outlet unit (20) at the shortest distance.

[0050] Meanwhile, the water outlet unit (20) can be installed so as to be rotatable on the upper part of the work table (2). As the water outlet unit (20) is installed so as to be rotatable, the user can approach the water outlet unit (20) from various angles as needed to receive purified water from the water purifier (1).

[0051] FIG. 2 is a cross-sectional view illustrating a discharge unit according to one embodiment of the present disclosure. Referring to FIG. 2, the discharge unit (20) may include a housing (21), a discharge pipe (22), and a discharge control valve (23).

[0052] The housing (21) is a configuration for forming the exterior of the water discharge unit (20). The housing (21) may be formed in a cylindrical shape, but is not limited thereto. The housing (21) may include a water discharge pipe (22) and a water discharge control valve (23) inside. The housing (21) may include a first housing (211) extending upward from the water purification unit (10) and a second housing (212) extending by being bent horizontally from the upper end of the first housing (211).

[0053] The first housing (211) and the second housing (212) may be formed integrally, but are not limited thereto. For example, the first housing (211) and the second housing (212) may be formed separately and then combined.

[0054] The outlet pipe (22) is configured to discharge purified water from the water purification unit (10) to the outside of the outlet unit (20). One end of the outlet pipe (22) can be connected to the internal water supply pipe (200), and the other end can extend to the end of the second housing (212) and be connected to the outside space. The area where an opening is formed at the other end of the outlet pipe (22) so that the outlet pipe (22) is connected to the outside of the outlet unit (20) is referred to as an outlet port (222).

[0055] The outlet pipe (22) may be a pipe with an empty interior, and an outlet path (221) through which purified water from the purification unit (10) can flow may be formed along the empty space inside.

[0056] The water discharge control valve (23) is configured to control the discharge of purified water from the water purification unit (10) to the outside of the water discharge unit (20) through the water discharge pipe (22).

[0057] The water discharge control valve (23) may be provided to penetrate a portion of the water discharge pipe (23). In other words, the water discharge control valve (23) may be positioned on the water discharge path (221) to open or close the water discharge path (221). When the water discharge control valve (23) opens the water discharge path (221), purified water from the water purification unit (10) may be discharged to the outside of the water discharge unit (20) along the water discharge path (221), and when the water discharge control valve (23) closes the water discharge path (221), purified water may accumulate in the water discharge path (221).

[0058] Meanwhile, the water discharge unit (20) may further include a water discharge control unit (not shown). The water discharge control unit is configured to control the water discharge control valve (23). The user can open or close the water discharge control valve (23) by controlling the water discharge control unit. Accordingly, whether purified water is discharged outside the water discharge unit (20) can be controlled.

[0059] The discharge control unit may be provided on the upper part of the first housing (211), but is not limited thereto.

[0060] Meanwhile, the discharge unit (20) may further include a guider (30), which will be described later.

[0061] FIG. 3 is an enlarged view of portion A of FIG. 2 to explain a guide according to one embodiment of the present disclosure. FIG. 4 is a cross-sectional view taken along line B-B' of FIG. 2 to explain a guide path according to one embodiment of the present disclosure. FIG. 5 is an exploded view to explain a guide.

[0062] Referring to FIGS. 3 to 5, the guider (30) may include a case (31), a guide path (32), a rotating part (33), a nozzle part (34), and a cover (35). The guider (30) is configured to guide the direction of distribution of water discharged through the water outlet (222). The guider (30) may be coupled to an end of the second housing (212) of the water discharge unit (20).

[0063] The case (31) is a configuration that forms the exterior of the guider (30) and protects the internal structure of the guider (30) from the external environment. The case (31) may include an upper case (311) and a lower case (312).

[0064] The upper case (311) may include an upper case top surface (3111) and an upper case side surface (3112).

[0065] The upper case top surface (3111) is configured to be in contact with the end of the discharge unit (20). The upper case top surface (3111) can be formed in the shape of a circular plate to correspond to the end of the discharge unit (20).

[0066] The upper case side (3112) can be formed to protrude in the opposite direction of the outlet unit (20) from the edge of the upper case upper surface (3111) perpendicular to the upper case upper surface (3111).

[0067] Due to this, a sunken receiving space (S1) toward the discharge unit (20) can be formed.

[0068] The inner surface of the upper case side (3112) may have a spiral-shaped joining groove (groove, 311a) formed so that it can be joined with the lower case (312).

[0069] The lower case (312) can be formed into a circular ring shape to be coupled to the inner surface of the upper case (311).

[0070] The outer surface of the lower case (312) may be formed with a spiral-shaped engaging protrusion (312a) so that it can be rotated and inserted into the inner surface of the upper case side (3112). That is, the outer surface of the lower case (312) may be formed with a engaging protrusion (312a) corresponding to the spiral-shaped engaging groove (311a) formed on the inner surface of the upper case side (3112).

[0071] A sealing protrusion (312b) for supporting a sealing member (not shown) may be formed at the lower portion of the coupling protrusion (312a) of the lower case (312).

[0072] The sealing protrusion (312b) may be formed to protrude perpendicular to the outer surface of the lower case (312) and may be formed to have a length corresponding to the outer diameter of the upper case side (3112).

[0073] A sealing member (313) may be provided between the upper case (311) and the lower case (312). The sealing member is configured to prevent water flowing inside the case (31) from leaking between the upper case (311) and the lower case (312).

[0074] The sealing member may be silicone (S1i), but the material of the sealing member is not limited thereto, and any material that can hermetically close the space between the upper case (311) and the lower case (312) can be applied without limitation.

[0075] The sealing member may be formed in a ring shape of the lower case (312) and may be placed on the sealing protrusion (312b) of the lower case (312).

[0076] When the lower case (312) is coupled to the upper case (311), if the coupling protrusion (312a) of the lower case (312) and the groove (311a) of the upper case (311) are not sufficiently sealed, water inside the case (31) may leak into the space between the upper case (311) and the lower case (312). However, as described above, the water can be prevented from leaking by placing the sealing member at the bottom of the coupling protrusion (312a) of the lower case (312).

[0077] The upper case (311) can be combined with the lower case (312) to form an internal receiving space (S1). A rotating part (33) and a nozzle part (34) can be placed in the receiving space (S1).

[0078] Meanwhile, a guide pipe (32) may be coupled to the upper side of the upper case (311). The guide pipe (32) is configured to guide the direction of water discharged from the discharge pipe (22). The guide pipe (32) may include a guide path (321) through which water can flow inside.

[0079] The guide pipe (32) is configured to be inserted into the outlet pipe (22). The guide pipe (32) may be formed to have a cylindrical shape. The outer diameter (R1) of the guide pipe (32) may be formed to correspond to the inner diameter (R2) of the outlet pipe (22).

[0080] The guide pipe (32) may be formed to protrude vertically upward from the upper case surface (3111). The length (L1) of the guide pipe (32) may be formed to correspond to the length (L2) of the outlet (222).

[0081] One end (32a) of the guide pipe (32) can be formed as an opening to communicate with the outlet passage (221), which is the internal space of the outlet pipe (22), and the other end (32b) can be coupled to the upper surface (3111) of the upper case. The other end (32b) of the guide pipe (32) can be coupled to the center of the upper surface (3111) of the upper case.

[0082] The guide passage (321) is configured to allow water to flow inside the guide pipe (32). The diameter (R3) of the guide passage (321) may be formed to correspond to the diameter (R4) of the outlet passage (221). Since the diameter (R3) of the guide passage (321) is formed to be smaller than the diameter (R4) of the outlet passage (221), the phenomenon of the water pressure decreasing due to an increase in the flow rate of the water discharged by capillary phenomenon can be prevented.

[0083] The guide euro (321) can be formed by bending and extending from the center of the case (31) toward one side of the case (31) so that water discharged from the discharge unit (20) can be supplied to one area of ​​the rotating part (33).

[0084] That is, the guide euro (321) may include a vertical portion (3211) and an inclined portion (3212).

[0085] Due to this, the water discharged from the discharge unit (20) can be concentrated and dropped only in a specific area of ​​the rotating part (33), thereby providing power to rotate the rotating part (33).

[0086] The rotating part (33) is configured to rotate by the water discharged from the discharge unit (20) so that the discharged water can be sprayed over a wide area. The rotating part (33) may include a rotating blade (331), a rotating shaft (332), and a blade receiving part (333).

[0087] The rotary blade (331) is configured to rotate by colliding with water flowing in from the guide passage (32). The rotary blade (331) may be arranged to have multiple blades arranged in a circumferential direction based on a rotary axis (332) that is arranged on the same axis as the center of the case (31). That is, the rotary blade (331) may be formed in the shape of a fan. The rotary blade (331) may be formed to protrude and extend downwardly from the rotary axis (332) toward the inner surface of the blade receiving portion (333).

[0088] The wing receiving portion (333) may be manufactured in a cylindrical shape corresponding to the outer circumference of the rotary blade (331) so as to accommodate the rotary blade (331). The wing receiving portion (333) may be formed to have a height greater than the length of the rotation shaft (332). Accordingly, even if freely falling water splashes upon colliding with the rotary blade (331), it can flow downwards of the rotary portion (33) by gravity after hitting the inner circumference of the wing receiving portion (333).

[0089] The outer diameter (R5) of the wing receiving portion (333) can be formed smaller than the inner diameter (R6) of the lower case (312). Accordingly, the rotating portion (33) can be received in the receiving space (S1) formed between the upper case (311) and the lower case (312).

[0090] The nozzle part (34) is configured to allow water passing through the rotating part (33) to be discharged to the outside of the guider (30). To this end, the nozzle part (34) may be placed on the lower side of the rotating part (33). The nozzle part (34) may include a nozzle part lower surface (341) and a nozzle part side surface (342).

[0091] The lower surface of the nozzle unit (341) is configured to have a plurality of outlet holes (3411). The lower surface of the nozzle unit (341) may be formed in a circular shape parallel to the upper surface (3111) of the upper case. The plurality of outlet holes (3411) may be formed to penetrate the lower surface of the nozzle unit (341) perpendicular to the ground. The number of outlet holes (3411) is not limited to that shown, and may be provided in a number less than or greater than that as needed.

[0092] The nozzle side (342) is configured to allow the nozzle side (34) to be coupled with the lower case (312). The nozzle side (342) can be manufactured to have a shape corresponding to the hook part (3121) of the lower case (312). That is, the nozzle side (342) can include a ring part (3421) that protrudes from the outer circumference of the nozzle side (342) and extends downwardly in a bent manner. The ring part (3421) can be formed along the outer circumference of the nozzle side (342) and can be coupled with the hook part (3121) of the lower case (312). Accordingly, the self-weight of the nozzle side (344) can be transferred to the lower case (312).

[0093] Meanwhile, the nozzle portion (34) may be formed to have an inner diameter (R8) larger than the outer diameter (R5) of the wing receiving portion so as to accommodate the rotating portion (33). Accordingly, the rotating portion (33) may be mounted and coupled to the nozzle portion (34).

[0094] Due to this, the weight of the rotating part (33) can be transferred to the nozzle part (34), and the weight of the rotating part (33) and the nozzle part (34) can be transferred to the lower case (312).

[0095] In addition, since the rotating part (33) and the nozzle part (34) are combined, when the rotating part (33) rotates due to water passing through the guide pipe (32), the nozzle part (34) can rotate together.

[0096] The cover (35) is configured to cover the nozzle unit (34) and protect the nozzle unit (34) from the external environment. The cover (35) can be coupled to the lower side of the nozzle unit. The cover (35) can be formed in the shape of a plate having a hollow portion so that a plurality of outlet holes (3411) are exposed to the outside of the outlet unit (20).

[0097] FIG. 6 is a drawing for explaining the radius at which water is sprayed from a nozzle unit according to one embodiment of the present disclosure. Referring to FIG. 6, as the nozzle unit (34) rotates together with the rotating unit (33), water can be discharged to the outside of the guider (30).

[0098] Water passing through the plurality of outlet holes (3411) formed to penetrate the lower surface (341) of the nozzle unit can fall and be discharged to the outside of the guider (30) by gravity in the direction of the ground. As the nozzle unit (34) rotates, the water can fall in an arc with a constant curvature due to centrifugal force. Accordingly, the water sprayed through the rotating nozzle unit (34) can be supplied to an area of ​​a circle having a constant diameter. At this time, the area of ​​the circle can be proportional to the size of the centrifugal force acting on the water passing through the nozzle unit (34). That is, the greater the speed of the water passing through the nozzle unit (34), the greater the area of ​​the circle can be supplied to.

[0099] In addition, as the plurality of outlet holes (3411) are arranged closer to the outer diameter of the nozzle portion (341), water can be supplied to a circular area having a larger diameter.

[0100] Fig. 7 is a cross-sectional view illustrating a water discharge unit according to another embodiment of the present disclosure. Fig. 8 is an enlarged view of portion C of Fig. 7 to illustrate a guider according to another embodiment of the present disclosure. Fig. 9 is an exploded view illustrating a guider according to another embodiment of the present disclosure. Referring to Figs. 7 to 9, the guider (40) may include a case (41), a guide pipe (42), and a rotating part (43). Hereinafter, the purpose of the guider (40) and the overlapping contents described with respect to the guide pipe (42) and the rotating part (43) with respect to Figs. 3 to 5 will be omitted.

[0101] The case (41) is a configuration that forms the exterior of the guider (40) and protects the internal structure of the guider (40) from the external environment. The case (41) may include an upper case (411) and a lower case (412).

[0102] The upper case (411) is configured to be in contact with the end of the outlet unit (20), and may be formed to have a shape corresponding to the end of the outlet unit (20). Specifically, the upper case (411) may include an upper case upper surface (4111) formed in the shape of a disc and an upper case side surface (4112) formed by protruding downward from the upper case upper surface (4111).

[0103] A guide pipe (42) can be coupled to the upper portion of the upper case top surface (4111). The discharge unit (20) and the upper case (411) can be coupled by inserting the guide pipe (42) into the discharge port (222).

[0104] The lower case (412) is configured to be coupled to the lower side of the upper case (411). The lower case (412) may include a lower case lower surface (4122) and a lower case side surface (4123). The lower case lower surface (4122) may be formed in a circular shape corresponding to the upper case upper surface (4111). The lower case side surface (4123) may be formed to protrude from the lower case lower surface (4122) toward the upper case (411) along the outer edge of the lower case lower surface (4122).

[0105] A spiral-shaped engaging protrusion (412a) may be formed on the outer surface of the lower case side (4123). The engaging protrusion (412a) may be rotatably inserted into a spiral-shaped engaging groove (411a) formed on the inner surface of the upper case (411). Accordingly, the lower case (412) may be stably fixed to the upper case (411).

[0106] By combining the upper case (411) and the lower case (412), an accommodation space (S2) can be formed between the upper case (411) and the lower case (412). The accommodation space (S2) is a space in which the rotating part (43) can be accommodated.

[0107] The lower case (412) may include a plurality of outlet holes (4121). The plurality of outlet holes (4121) may be formed to penetrate the lower case (412) so that water passing through the guide pipe (42) and the rotating part (43) can be discharged to the outside of the guider (40).

[0108] The number of multiple outlets (4121) is not limited to that shown, and may be provided in various numbers depending on the case.

[0109] The plurality of outlet holes (4121) may include vertical outlet holes (4121a). The vertical outlet holes (4121a) may be formed to be perpendicular to the ground and penetrate the lower surface (4122) of the lower case (412). The description of the vertical outlet holes (4121a) will be omitted to the extent that it overlaps with the description of the plurality of outlet holes (3411) in FIGS. 3 to 5.

[0110] Meanwhile, the plurality of outlet holes (4121) may further include a side outlet hole (4121b). The side outlet hole (4121b) is configured to guide water that has flowed to the side of the lower case (412) by the rotating part (43) so that it can be discharged to the outside of the guider (40) while maintaining centrifugal force.

[0111] The side outlet (4121b) can be formed to penetrate the connecting surface (4124).

[0112] The connecting surface (4124) is configured to connect the lower case bottom surface (4122) and the lower case side surface (4123). The connecting surface (4124) may be an inclined surface having an angle (A) of approximately 45 degrees from the lower case bottom surface (4122).

[0113] The connecting surface (4124) may be extended from the outer periphery of the lower case bottom surface (4122) toward one end of the lower case side surface (4123).

[0114] Due to this, water that flows into the guider (40) and then collides with the rotating part (43) or splashes onto the inner surface of the lower case side (4123) as the rotating part (43) rotates can flow toward the ground along the inner surface of the lower case side (4123) by gravity and then be transferred to the lower surface (4122) of the lower case along the inner surface of the inclined connecting surface (4124).

[0115] Meanwhile, water that has splashed toward the side outlet (4121b) can pass through the side outlet (4121b) and be discharged to the outside of the guider (40).

[0116] FIG. 10 is a drawing for explaining the arrangement of a plurality of outlet holes according to another embodiment of the present disclosure. Referring to FIG. 10, a plurality of vertical outlet holes (4121a) and a plurality of side outlet holes (4121b) may be formed in the lower case (412). In this case, the plurality of vertical outlet holes (4121a) and the plurality of side outlet holes (4121b) may be arranged on different axes. For example, if the axis along which the plurality of vertical outlet holes (4121a) are arranged is the X-axis, the plurality of side outlet holes (4121b) may be arranged on the Y-axis, which is different from the X-axis.

[0117] Accordingly, water subjected to centrifugal force by the rotation of the rotating part (42) is discharged only through the side discharge hole (4121b) without passing through the vertical discharge hole (4121a), thereby enabling water to be discharged over a wide radius.

[0118] Fig. 11 is a drawing for explaining the radius of water spray from a guide according to another embodiment of the present disclosure. Referring to Fig. 11, water passing through the side discharge hole (4121b) by the rotation of the rotating part (43) can be discharged into the external space of the guide (40) while maintaining centrifugal force.

[0119] Water passing through the side outlet (4121b) may experience centrifugal force and gravity toward the ground. Accordingly, water passing through the side outlet (4121b) may fall toward the ground in a parabolic curve.

[0120] Meanwhile, water passing through the vertical outlet (4121a) is subjected to centrifugal force by the rotating part (43), but after colliding with the lower case surface (4122), the centrifugal force is canceled out, so it can fall freely toward the ground due to gravity.

[0121] In this way, since the falling directions of the water passing through the vertical outlet (4121a) and the side outlet (4121b) are different, the water passing through the guide (40) can be supplied to a wider range than the cross-sectional area of ​​the outlet (222).

[0122] The radius (drainage radius, D) at which water passing through the guider (40) is discharged can be determined by the water passing through the side outlet (4121b). That is, if the speed of water passing through the side outlet (4121b) is high, the drainage radius (D) can increase. Conversely, if the speed of water passing through the side outlet (4121b) is low, the drainage radius (D) can decrease.

[0123] The user can adjust the pressure of the water discharged from the water purifier (1) through the water discharge control unit (24) as needed. Accordingly, the user can supply water with an appropriate discharge radius (D) to each cup having a different surface area.

[0124] As described above, the water purifier (1) including the guide (30, 40) according to the present disclosure can receive water through the guide pipe (32, 42) coupled with the water outlet (222) provided at the end of the water outlet pipe (22). Water flowing into the receiving space (S1, S2) inside the case (31, 41) through the guide path (321) bent and extended toward one side of the case (31, 41) can collide with the rotating part (33, 43) and rotate the rotating part (33, 43). The water can pass through the water outlet (3411) of the nozzle part (34) that rotates together with the rotating part (33) or the side water outlet (4121b) formed on the lower surface (4122) of the lower case and be subjected to both centrifugal force and gravity as it rotates. In this way, water passing through the outlet hole (3411) of the nozzle unit (34) or the side outlet hole (4121b) of the lower case bottom surface (4122) can be discharged to the outside of the guider (30, 40) while drawing a parabola with respect to the ground. Accordingly, the user can be supplied with water sprayed over a wider range than the cross-sectional area of ​​the outlet hole (222).

[0125] Although various embodiments of the present disclosure have been individually described above, each embodiment does not necessarily have to be implemented alone, and the configuration and operation of each embodiment may be implemented in combination with at least one other embodiment.

[0126] In addition, although the preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and various modifications may be made by a person having ordinary skill in the art to which the present invention pertains without departing from the gist of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical idea or prospect of the present disclosure.
