Description

Technical Field

[0001] The present invention relates to a water purifier and an operation method thereof. More specifically, by simply and accurately rotating the faucet 90 degrees, the faucet can be installed at an optimal position according to the usage environment, and the faucet part and the built-in compatible unit can be selectively coupled. The present invention relates to a water purifier.

Background Art

[0002] Kitchen spaces are designed in various ways, and thus the need to install water purifiers at optimal positions in various environments has increased. Accordingly, technologies for variably positioning the water outlet part of water purifiers have been developed.

[0003] For example, Korean Registered Patent No. 10-1828260 discloses a technology in which the water outlet part of a water purifier rotates within a range of 180 degrees to change the position where water is discharged. Korean Published Patent No. 10-2024-0104876 also discloses a technology in which the water outlet part of a water purifier is rotated to change the position and thus change the position where water is discharged.

[0004] However, in water purifiers developed to date, only the water outlet terminal of the water outlet part is rotated instead of the entire faucet, and overall, it is somewhat restrictive to vary the installation of water purifiers suitable for various installation environments.

[0005] In addition, in order to rotate the entire faucet to vary the installation of the water purifier, another specialized operator is required to disassemble and assemble the water purifier, and there are limitations for general users to arbitrarily perform such work.

[0006] Furthermore, the needs of consumers for water purifiers that can be compatible with tabletop water purifiers and built-in water purifiers according to the installation environment have increased, and the development of such compatible water purifiers is also necessary.

Summary of the Invention

Problems to be Solved by the Invention

[0007] The present invention is based on the above, and its objective is to provide a water purifier and a method for operating it that allows the faucet to be rotated easily and accurately in a 90-degree direction, thereby improving space utilization by positioning the faucet in the optimal location depending on the usage environment, and furthermore, allowing the general user to easily perform the rotation operation without any additional tools.

[0008] Another object of the present invention is to provide a water purifier and a method for this interchangeability, which allows for interchangeability between a tabletop water purifier and a built-in interchangeable unit by selectively combining a faucet section and a built-in interchangeable unit, and which can be easily interchanged even by non-experts. [Means for solving the problem]

[0009] A water purifier in one form for achieving the aforementioned objectives of the present invention is characterized by including a main body, a fixed unit slidably connected to the upper surface of the main body, and a faucet that is fixed to the upper surface of the main body by the fixed unit and rotates from a first position to a second position when a play space is formed between the fixed unit and the faucet as the fixed unit slides.

[0010] The faucet section includes a water outlet section for dispensing purified water and a faucet block on which the water outlet section is formed, and the position of the water outlet section changes as the faucet block rotates from the first position to the second position.

[0011] The faucet block has a square block shape, and the faucet block switches 90 degrees between the first position and the second position.

[0012] The system further includes a rotating unit for fixing or releasing the fixing unit from the upper surface of the main body.

[0013] When the rotating unit releases the fixed unit from the main body, the fixed unit slides, creating the play space.

[0014] The rotating unit includes a rotating bar that extends along the upper part of the main body and is coupled to or uncoupled from the fixed unit, and a rotating portion at one end of the rotating bar that is exposed to the outside of the main body.

[0015] The rotating part is operated to rotate, and the rotating bar is coupled to or uncoupled from the fixed unit.

[0016] The main body includes a support block provided on the upper part, and the support block includes a guide surface that guides the movement of the rotating bar accompanying the rotation of the rotating part.

[0017] The fixing unit includes a fixing body having a sliding surface and a first fixing block formed on the sliding surface, which is coupled to or uncoupled from the rotating bar.

[0018] The first fixing block includes a first fixing frame protruding from the sliding surface and a first fixing guide formed inside the first fixing frame, each having a first fixing groove into which the rotating bar is inserted.

[0019] The system further includes a guide unit provided on the main body for guiding the sliding of the fixed unit.

[0020] The guide unit includes a central guide portion that guides the fixed unit, and first and second guide portions on both sides of the central guide portion that guide the sliding range of the fixed unit.

[0021] Each of the first and second guide portions includes a front end guide groove that guides the fixed unit to a first position when it slides, and a rear end guide groove that is a predetermined distance from the first front end guide groove and guides the fixed unit to a second position when it slides.

[0022] The fixing unit is brought into contact with the faucet part at the first position and forms a play space between the faucet part at the second position.

[0023] The fixing unit includes a central protruding part guided along the central guide part, and first and second sliding parts moving along the first and second guide parts on both sides of the central protruding part.

[0024] The faucet part includes a rotary connection part formed on the rotary surface of the faucet body, a rotary plate rotatably connected to the rotary connection part, and a fixing plate fastened to the rotary connection part.

[0025] The rotary connection part includes an arc-shaped rotary groove part, and the rotary plate includes a guide protrusion guided and moved along the rotary groove part.

[0026] The rotary plate includes a guide block protruding in an arc shape, and first and second fixing parts respectively protruding from both ends of the guide block. The fixing plate includes a fastening block moving along the guide block, and first and second fastening parts restricting relative movement with the rotary plate at both ends of the fastening block.

[0027] In the method for operating a water purifier according to another aspect for realizing the object of the present invention described above, the steps include releasing the coupling state between the fixing unit and the main body part, sliding the fixing unit on the upper surface of the main body part to form a play space between the fixing unit and the faucet part, rotating the faucet part from the first position to the second position, sliding the fixing unit on the upper surface of the main body part to bring it into close contact with the faucet part, and coupling the fixing unit to the main body part.

[0028] In the step of releasing the connection state between the fixing unit and the main body, rotate the rotating part exposed outside the main body in one direction to release the connection state between the rotating bar connected to the rotating part and the fixing unit. In the step of connecting the fixing unit to the main body, rotate the rotating part in the other direction to connect the rotating bar to the fixing unit.

[0029] In a water purifier according to an aspect for realizing another object of the present invention described above, it includes a main body, a water outlet part where purified water is discharged, a faucet part coupled to the upper surface of the main body, and a connection unit connected to a pipe through which the purified water is provided. When the faucet part is removed from the upper surface, it further includes a compatible unit coupled to the upper surface.

[0030] When the faucet part is coupled, it is used as a tabletop type. When the compatible unit is coupled, it is used as a built-in type.

[0031] The water outlet part discharges the purified water downward from the faucet part, and the connection unit provides the purified water upward from the compatible unit.

[0032] It further includes a fixing unit coupled to the upper surface so as to be adjacent to the faucet part. When the faucet part is coupled, the fixing unit slides on the upper surface and adheres to the faucet part. When releasing the connection of the faucet part, the fixing unit slides on the upper surface to form a play space between the fixing unit and the faucet part.

[0033] When releasing the connection of the faucet part, release the connection part provided in the play space to remove the faucet part and the fixing unit from the main body.

[0034] It further includes a rotating unit for fixing or releasing the fixing unit or the compatible unit to or from the upper surface.

[0035] A method for interchangeable water purifiers in another manner to achieve other objectives of the present invention as described above, characterized in that it includes the steps of: releasing the coupling between a fixed unit and a main body; removing a faucet including a water outlet from which purified water is dispensed, and the fixed unit from the upper surface of the main body; positioning an interchangeable unit having a coupling unit connected to a pipe from which purified water is supplied on the upper surface; and coupling the interchangeable unit and the main body.

[0036] The process includes the steps of releasing the connection between the fixed unit and the main body, sliding the fixed unit across the upper surface of the main body to form a play space between the fixed unit and the faucet, and releasing the connection provided in the play space.

[0037] In the step of releasing the connection between the fixed unit and the main body, the rotating part exposed to the outside of the main body is rotated in one direction to release the connection between the rotating bar connected to the rotating part and the fixed unit. In the step of connecting the interchangeable unit and the main body, the rotating part is rotated in the other direction to connect the rotating bar to the interchangeable unit. [Effects of the Invention]

[0038] According to the present invention, the faucet can rotate to a first position and a second position, and its position can be changed considering the installation environment, thereby improving space utilization and user convenience. Here, the faucet is fixed in place by a fixing unit in both the first and second positions, respectively, so more stable fixing is possible.

[0039] In contrast, if the fixed unit forms a predetermined play space through simple sliding movement, the faucet portion becomes rotatable, and the position of the faucet portion can be easily changed by rotation. In particular, the fixed state or the sliding state due to the release of the fixed unit is realized by the operation of the rotating unit, which can be easily done by the user rotating a lever from the outside. Therefore, an ordinary user who is not a specialist can simply operate the lever, which is the rotating part, to switch between the fixed state and the sliding state of the fixed unit, improving user convenience and operability.

[0040] Specifically, the coupling and uncoupling are achieved by coupling and uncoupling a first fixing block formed on the bottom surface of the fixing unit with a rotating bar included in the rotating unit. This has the advantages of being easy to design and manufacture, having stable and easy operation, and being manufactured to have sufficient durability.

[0041] In particular, by guiding the variable position of the rotating bar through the guide surface of the support block, the coupling and uncoupling between the rotating bar and the first fixed block can be performed more stably.

[0042] On the other hand, by guiding the sliding of the fixing unit with the guide unit, only sliding in a predetermined sliding direction and position is guided, and the fixing and release between the faucet and the fixing unit can be performed stably. In other words, the central guide portion of the guide unit and the central protrusion portion of the fixing unit stably guide the sliding direction of the fixing unit, and the first and second guide portions of the guide unit and the first and second sliding portions of the fixing unit can stably set the sliding range of the fixing unit.

[0043] Furthermore, the faucet section is guided in the direction of rotation by the rotating plate and the fixed plate, and its range of rotation is also limited. This allows the user to rotate the faucet section within a limited range in terms of both direction and degree of rotation, minimizing damage to the faucet section caused by unnecessary rotation.

[0044] Furthermore, by selectively connecting the faucet section and the compatible unit to the main body, it is possible to choose between using it as a tabletop water purifier or a built-in water purifier. This allows for the installation of a water purifier more suitable for various usage environments, improving usability, convenience, and space utilization.

[0045] Furthermore, since the faucet and the interchangeable unit can be easily attached and detached by releasing the fastening, even ordinary users who are not experts can perform the work themselves, thereby improving user convenience.

[0046] Here, the fixing unit that secures the position of the faucet is moved by sliding, creating a play space between it and the faucet, and the fastening part is released while exposed to the outside through the play space. Therefore, the fastening part can be easily released by the simple action of sliding the fixing unit.

[0047] In particular, the state in which the fixed unit is slidable or the state in which the faucet is fixed is achieved by the operation of the rotating unit, and can be easily performed by the user from the outside by rotating the lever. Similarly, the interchangeable unit is also fixed to the main body by rotating the lever.

[0048] Therefore, ordinary users who are not experts can simply operate the lever, which is a rotating part, to switch between the fixed state and the sliding state of the fixed unit, and to switch between the fixed state and the unlocked state of the interchangeable unit, thereby improving user convenience and operability.

[0049] Specifically, the connection and disconnection of the fixed unit and the interchangeable unit are achieved by connecting and disconnecting the fixed blocks formed on the bottom surfaces of the fixed unit and the interchangeable unit with the rotating bar included in the rotating unit. This offers the advantages of being easy to design and manufacture, having stable and easy operation, and being manufactured to have sufficient durability. [Brief explanation of the drawing]

[0051] The present invention can be modified in various ways and may take on various forms; embodiments are described in detail below.

[0052] The terms used herein are for the sole purpose of distinguishing one component from another. The terms used herein are used merely to describe specific embodiments and are not intended to limit the invention.

[0053] Preferred embodiments of the present invention will be described in more detail below with reference to the attached drawings.

[0054] Figures 1a to 1f are perspective views showing a water purifier according to one embodiment of the present invention and each step of the operation method of the water purifier. Figure 2 is a perspective view showing the rotating unit in Figure 1a. Figure 3 is a perspective view showing the fixed unit in Figure 1a.

[0055] First, the water purifier 10 according to this embodiment will be described with reference to Figures 1a, 2, and 3. Specifically, the water purifier 10 according to this embodiment includes a main body 100, a rotating unit 200, a fixed unit 300, and a faucet 400.

[0056] The main body portion 100 forms the body of the water purifier 10 and includes a first surface 110, a second surface 120, a third surface 180, a bottom surface 130, and a top surface 140, and has an overall rectangular block shape. However, the shape and structure of the main body portion 100 are not limited to this. On the other hand, the interior of the main body portion 100 is provided with the necessary components for the operation of the water purifier 10, and a detailed explanation is omitted.

[0057] The first surface 110 is a surface facing the first direction (X), and the second surface 120 is perpendicularly connected to the first surface 110, that is, a surface facing the second direction (Y) perpendicular to the first direction (X). The third surface 180 is a surface facing the second surface 120 in the second direction (Y), and the bottom surface 130 and the top surface 140 are surfaces facing each other along the third direction (Z). Here, the third direction (Z) is defined as the direction perpendicular to the first and second directions (X, Y).

[0058] As shown in Figure 2, the rotating unit 200 includes a rotating section 210, an insertion section 220, and a rotating bar 230, and is coupled to the upper part of the main body 100 as shown in Figure 1a.

[0059] The rotating portion 210 is coupled to the main body portion 100 so as to be exposed on the outside of the first surface 110 of the main body portion 100, and corresponds to a lever that is directly operated by the user. The insertion portion 220 is positioned opposite the rotating portion 210 and is located on the inside of the surface opposite the first surface 110. Here, the rotating bar 230 extends between the rotating portion 210 and the insertion portion 220 and extends through the upper space 141 (see Figure 4a) of the main body portion 100.

[0060] A more detailed explanation of the aforementioned rotating unit 200 will be provided later.

[0061] The fixing unit 300 is coupled to one side of the upper surface 140 of the main body 100 and includes a fixing body 310 that is rectangular in shape overall. The fixing unit 300 does not require any other parts to be provided inside and is a structure that either fixes the position of the faucet 400 or slides to form a predetermined play space 101 for the rotation of the faucet 400.

[0062] As shown in Figure 3, a first fixing block 320 is formed on the sliding surface 312, which is the bottom surface of the fixing body 310 of the fixing unit 300.

[0063] The first fixing block 320 includes a first fixing frame 321 protruding from the sliding surface 312 and first fixing guides 322, at least one of which are arranged parallel to each other in the first direction (X) inside the first fixing frame 321.

[0064] The first fixing frame 321 has a rectangular block shape as a whole, extending in the first direction (X), and is open downwards. At least one of the first fixing guides 322 is arranged along the first direction (X) in the internal space in which the first fixing frame 321 is formed, and each has the same shape.

[0065] Here, a predetermined first fixing groove 323 is formed on the lower side of the first fixing guide 322, and the first fixing groove 323 has a semicircular shape. As a result, the rotating bar 230 is inserted and positioned inside the first fixing groove 323, as will be described later.

[0066] The faucet portion 400 is coupled to the other side of the upper surface 140 of the main body portion 100 and is positioned adjacent to the fixing unit 300. That is, as shown in Figure 1a, the faucet portion 400 and the fixing unit 300 are arranged in contact with each other on the upper surface 140, and this contact state allows the faucet portion 400 to be stably fixed in place by the fixing unit 300.

[0067] On the other hand, the faucet section 400 includes a water outlet section 430 (see Figure 8), and is equipped with piping for dispensing purified water, etc., and although not shown, a display unit that provides various status and information of the water purifier can be formed therein. Here, the water outlet section 430 is exposed facing downward (the negative third direction (-Z)) and dispenses purified water downward to the user.

[0068] Furthermore, the faucet section 400 also includes a square block-shaped faucet body 410 as a whole. Here, Figure 1a shows that the size of the block of the faucet section 400 is larger than the size of the block of the fixing unit 300, but it is not limited to this, and it is sufficient that the position of the faucet section 400 can be fixed by the fixing unit 300.

[0069] Based on the basic structure of the water purifier 10 described above, the operation method of the water purifier 10, that is, the rotational operation of the faucet part 400 in the water purifier 10, will be explained below with reference to Figures 1a to 1f.

[0070] First, as shown in Figure 1a, at the first position (the position of the faucet in Figure 1a is defined as the first position), the faucet 400 is fixed in place by the fixing unit 300. Here, the faucet 400 is positioned such that the water outlet 430 faces the second surface 120. That is, if the faucet 400 is a rectangular block that extends relatively long in one direction, the direction in which it extends relatively long is parallel to the second direction (Y).

[0071] On the other hand, although not shown in the figures, in the first position, the rotating bar 230 of the rotating unit 200 is coupled to the first fixing groove 323, and the fixing unit 300 is stably fixed in place, providing stable position fixing to the faucet section 400.

[0072] In this first position, the user can extract and use purified water from the water outlet 430 on the second surface 120 side.

[0073] Subsequently, in order to switch the direction of water extraction, the direction switching operation of the faucet section 400 shown in Figures 1b to 1f is performed.

[0074] First, as shown in Figure 1b, the rotating part 210, which is exposed to the outside on the first surface 110 of the main body 100, is switched in the direction indicated by the arrow. That is, the rotating part 210 can be rotated, for example, 90 degrees clockwise from its position in the first position.

[0075] As a result of the rotational movement of the rotating part 210, the rotating bar 230 coupled to the first fixing groove 323 moves outward from the first fixing groove 323, thereby releasing the fixing unit 300 from its fixed state.

[0076] Subsequently, as shown in Figure 1c, the fixed state of the fixing unit 300 is released, causing the fixing unit 300 to slide in the positive second direction (+Y) as indicated by the arrow.

[0077] Here, the fixed unit 300 is guided in its sliding direction and sliding range by the guide unit 500, which will be described later, and is moved in the positive second direction (+Y). The specific details of how the sliding direction and sliding range of the fixed unit 300 are guided will be described later.

[0078] Thus, a predetermined clearance space 101 is created between the fixed surface 311 of the fixed unit 300 and the faucet portion 400. Here, the size of the clearance space 101 only needs to be sufficient to allow the faucet portion 400, which will be described later, to rotate, and with this in mind, the sliding range of the fixed unit 300 is also limited.

[0079] Subsequently, as shown in Figure 1d, with the play space 101 created, the faucet portion 400 is rotated around the third direction (Z) as its rotational axis to switch the extension direction of the faucet portion 400. Here, the faucet portion 400 can rotate, for example, by 90 degrees, and more specific details regarding the rotation guide of the faucet portion 400 will be described later.

[0080] Thus, the water outlet portion 430 of the faucet portion 400 is positioned facing the first surface 110.

[0081] Subsequently, as shown in Figure 1e, with the faucet portion 400 rotated, the fixing unit 300 is slid in the opposite direction to the direction of movement in Figure 1c, that is, in the negative second direction (-Y) as indicated by the arrow. Thus, the fixing surface 311 of the fixing unit 300 comes into close contact with the faucet portion 400 once again.

[0082] Subsequently, as shown in Figure 1f, the rotating part 210 is switched back to the position shown in Figure 1a in order to fix the position of the fixing unit 300 which is in close contact with the faucet part 400. That is, the rotating part 210 is rotated again, for example, counterclockwise, as indicated by the arrow. Thus, although not shown in the figure, the rotating bar 230 connected to the rotating part 210 also changes position and is coupled onto the first fixing groove 323 of the first fixing guide 322.

[0083] In addition, as shown in Figure 1f, the fixing unit 300 is fixed in a position that is in close contact with the faucet portion 400, and as a result, the position of the faucet portion 400 is also fixed in a stable position.

[0084] If we consider the position of the faucet portion 400 in Figure 1f as the second position, then at the second position, the faucet portion 400 can dispense purified water or the like towards the first surface 110. That is, as mentioned above, if the faucet portion 400 is a rectangular block that extends relatively long in one direction, it is positioned such that the direction in which it extends relatively long is parallel to the first direction (X).

[0085] Furthermore, in order to switch the direction of the faucet 400 from the second position to the first position, the steps can be reversed from those described above, that is, from the steps shown in Figure 1f to Figure 1a.

[0086] As described above, the faucet section 400 can be switched in direction by 90 degrees from the first position to the second position, and a stable fixed state can be maintained at each position by fixing the fixing unit 300. Furthermore, since this direction switching of the faucet section 400 is performed by switching the rotating section 210 by 90 degrees and sliding the fixing unit 300 in the second direction (Y), even ordinary users who are not experts can easily perform the above operation.

[0087] Therefore, the user can improve the convenience of installation and use by switching the direction of the faucet part 400 whenever necessary.

[0088] The following will provide a more detailed explanation of the coupling and uncoupling of the rotating bar 230 and the first fixed guide 322.

[0089] Figures 4a and 4b are enlarged views showing the rotation state of the rotating unit in Figure 1a. Figures 5a and 5b are side views showing the connection state of the rotating unit and the stationary unit in Figures 4a and 4b, respectively.

[0090] First, as shown in Figures 4a and 4b, in the rotating unit 200, the rotating part 210 is positioned exposed to the outside of the first surface 110, and here the rotating part 210 is located in a predetermined storage groove 111 formed on the outside of the first surface 110. Thus, the user can position their finger in the storage groove 111, which is recessed to a predetermined depth from the first surface 110, and perform the rotational operation of the rotating part 210 more easily.

[0091] Furthermore, in the rotating unit 200, the insertion portion 220 is located inside a predetermined insertion space 170 formed on the side opposite to the side where the storage groove 111 is formed. In other words, only the rotating portion 210 of the rotating unit 200 needs to be exposed to the outside, and the insertion portion 220, which is rotated by the rotational movement of the rotating portion 210, does not need to be exposed to the outside, but can be located inside the insertion space 170 and rotate by the rotational movement of the rotating portion 210. Here, although not shown in detail in the figures, the insertion space 170 can be formed to provide an appropriate space and necessary guides for the insertion portion 220 to rotate 90 degrees and change position.

[0092] As described above, with the rotating portion 210 and the insertion portion 220 positioned, the rotating bar 230 extends in the upper space 141 along the first direction (X). Here, it is sufficient for the rotating bar 230 to extend to a position close to the upper surface 140, and considering the position of the first fixed block 320, it can extend to a position located a predetermined depth inward from the upper surface 140.

[0093] As described above, the rotating bar 230 extending over the upper space 141 changes position as the rotating part 210 rotates 90 degrees from a first position to a second position, as shown in Figures 4a and 4b. More specifically, it can be confirmed that the rotating bar 230 changes position so that its height is lower in Figure 4b than in Figure 4a.

[0094] Here, another support block 160 is provided on the upper space 141, and the support block 160 is positioned to support the center of the rotating bar 230. The support block 160 has a block shape as a whole, and the guide surface 161 that supports the rotating bar 230 is formed to have a predetermined curved shape.

[0095] Thus, in Figure 4a, the rotating bar 230, which is in contact with the upper side of the guide surface 161, is guided along the guide surface 161 as the rotating part 210 rotates, and moves downward, so that in Figure 4b, it is in contact with the lower side of the guide surface 161.

[0096] In other words, the guide surface 161 has a quarter-circle shape when viewed along the first direction (X), and the rotating bar 230 changes position from the upper side to the lower side along the guide surface 161. As a result, the rotating bar 230 is positioned at a relatively high position in Figure 4a and at a relatively low position in Figure 4b.

[0097] The state of connection between the rotating bar 230 and the first fixed block 320, depending on the position of the rotating bar 230, is as follows.

[0098] That is, as shown in Figure 5a, at the first or second position (position in Figure 1a or Figure 1f), the rotating bar 230 is located above the guide surface 161, and as a result, the rotating bar 230 is inserted into the fixing groove 323 of the first fixing guide 322. Therefore, at the position shown in Figure 5a, the fixing unit 300 is fixed to the rotating unit 200, and the movement of the fixing unit 300 along the second direction (Y) is restricted.

[0099] In contrast, as shown in Figure 5b, as the rotating part 210 rotates, the rotating bar 230 moves along the guide surface 161 and, when it is positioned below the guide surface 161, the rotating bar 230 is positioned outside the fixing groove 323 of the first fixing guide 322. Therefore, in this position shown in Figure 5b, the fixing unit 300 is released from being fixed by the rotating unit 200, and the fixing unit 300 becomes capable of moving along the second direction (Y).

[0100] Thus, as shown in Figures 1c and 1e, the fixed unit 300 can slide along the second direction (Y).

[0101] The following explains how the sliding direction and sliding range of the fixed unit 300 are guided when it is slid. That is, as shown in Figures 1c and 1e, when the fixed unit 300 slides along the second direction (Y), it can be difficult for an average user who is not a specialist to determine how far the fixed unit 300 should slide. As will be described later, guiding the sliding direction and range of the fixed unit 300 can improve user convenience.

[0102] Figure 6 is a perspective view showing a guide unit formed on the third side of the main body in Figure 1a. Figures 7a and 7b are perspective views showing a fixed unit that slides along the guide unit in Figure 6.

[0103] First, as shown in Figure 6, a guide unit 500 is further provided on the third side surface 180 of the main body portion 100. Here, the guide unit 500 guides the sliding of the fixing unit 300 and can be provided on the upper side of the third surface 180 on which the fixing unit 300 is located.

[0104] In other words, the guide unit 500 extends from above the third surface 180 in a direction parallel to the upper surface 140.

[0105] More specifically, the guide unit 500 includes a guide frame 510, a central guide section 530, and first and second guide sections 540 and 550.

[0106] The guide frame 510 is a predetermined frame extending from above the third surface 180 in a direction parallel to the upper surface 140, with the central guide portion 530 and the first and second guide portions 540 and 550 formed on its upper surface. Here, the extension length of the guide frame 510 in the second direction (Y) can be appropriately formed considering the extension lengths of the central guide portion 530 and the first and second guide portions 540 and 550.

[0107] The central guide portion 530 extends in the second direction (Y) along the center of the guide frame 510 and includes a pair of spaced-apart central guides 531 and a central guide groove 532 formed inside the central guides 531.

[0108] The first guide portion 540 extends from one side of the central guide portion 530 in the second direction (Y). The first guide portion 540 includes a first guide groove 541 having a groove shape extending to a predetermined length, and first front end guide grooves 542 and first rear end guide grooves 543 formed at both ends of the first guide groove 541 in the second direction (Y).

[0109] The second guide portion 550 extends in the second direction (Y) from the other side of the central guide portion 530 and has the same shape as the first guide portion 540. That is, the second guide portion 550 includes a second guide groove 551 having a groove shape extending to a predetermined length, and a second front end guide groove 552 and a second rear end guide groove 553 formed at both ends of the second guide groove 551 in the second direction (Y), respectively.

[0110] On the other hand, the guide unit 500 is coupled to the sliding surface 312, which is the bottom surface of the aforementioned fixed unit 300, and the sliding configuration formed on the fixed unit 300 will be described with reference to Figure 3.

[0111] In other words, referring again to Figure 3, the fixing unit 300 includes a central projection 330 and first and second sliding parts 340 and 350, which are formed on the sliding surface 312, which is the bottom surface of the fixing body 310.

[0112] The central projection 330 is formed on the rear side of the sliding surface 312 of the fixed unit 300, along the second direction (Y). That is, the central projection 330 is coupled to the central guide portion 530, and the guide unit 500 is formed on the side of the third surface 180, so the central projection 330 should also be formed in a position close to the third surface 180.

[0113] The central projection 330 has a hook-like shape that protrudes downward from the sliding surface 312 by a predetermined length. As a result, the central projection 330 is positioned to be inserted into the central guide groove 532 described above. Both sides of the central projection 330 are guided by the central guide 531. Furthermore, as shown in Figures 7a and 7b, the central projection 330 is guided in the direction of movement by the central guide 531 and slides along the central guide groove 532 in the second direction (Y).

[0114] As described above, when the fixed unit 300 slides on the upper surface 140, the guide unit 500 can stably guide it so that the sliding direction is aligned with the second direction (Y).

[0115] On the other hand, the first sliding portion 340 is formed on one side of the central projection 330 and is coupled to the first guide portion 540 to limit the sliding range of the fixed unit 300.

[0116] In other words, the first sliding portion 340 includes a first line portion 341 and a first protrusion portion 342, and has a predetermined elasticity as a whole. That is, the first protrusion portion 342 has elasticity in the vertical direction within a predetermined range, and its position changes.

[0117] Thus, the first projection 342 is retracted into the first guide groove 541, slides along the first guide groove 541, and is fixed in a shape that allows it to be inserted into the first front end guide groove 542 or the first rear end guide groove 543. Such fixing force does not need to be relatively large; it should be sufficient to allow the range of the sliding stroke of the fixing unit 300 to be confirmed from the outside.

[0118] The same applies to the second sliding portion 350. That is, the second sliding portion 350 is formed on the other side of the central projection 330 and includes a second line portion 351 and a second projection 352, and has a predetermined elasticity as a whole. That is, the second projection 352 has elasticity within a predetermined range in the vertical direction, and its position changes.

[0119] Thus, the second projection 352 is retracted into the second guide groove 551, slides along the second guide groove 551, and is fixed in a shape that allows it to be inserted into the second front end guide groove 552 or the second rear end guide groove 553.

[0120] As described above, when the first and second protrusions 341 and 351 slide along the first and second guide grooves 541 and 551 and are then inserted into and fixed in the first and second front end guide grooves 542 and 552, the fixing unit 300 will be in close contact with the faucet portion 400 and will fix the faucet portion 400, as shown in Figure 7a.

[0121] In contrast, when the first and second protrusions 341 and 351 are slid along the first and second guide grooves 541 and 551 and then inserted into the first and second rear end guide grooves 543 and 553 and fixed, as shown in Figure 7b, a predetermined clearance 101 is formed between the fixing unit 300 and the faucet portion 400 when the fixing unit 300 is moved to its maximum extent in the second direction (Y).

[0122] Thus, the user can confirm the range of sliding movement of the fixing unit 300 in the second direction (Y) based on the state in which the first and second protrusions 341 and 351 are fixed to the first and second front end guide grooves 542 and 552, or the first and second rear end guide grooves 543 and 553.

[0123] The following will specifically describe the state in which rotation occurs when the faucet portion 400 switches position between the first position and the second position.

[0124] Figure 8 is an exploded perspective view showing the faucet section in Figure 1a. Figure 9a is a plan view showing the rotating surface of the faucet body in Figure 8, Figure 9b is a plan view showing the rotating plate in Figure 8, Figure 9c is a bottom view showing the rotating plate in Figure 8, and Figure 9d is a plan view showing the fixed plate in Figure 8.

[0125] First, as shown in Figure 8, the faucet section 400 includes a rotating connecting section 420 formed on the faucet body 410, a rotating plate 430, and a fixed plate 440. Here, the rotating plate 430 is fixed to the upper surface 140 of the body section 100, and the rotating connecting section 420 and the fixed plate 440 are fixed to each other.

[0126] Thus, with the rotating plate 430 fixed, the faucet body 410 and the fixing plate 440 are integrally connected to each other and rotate relative to the rotating plate 430, changing their orientation within a 90-degree range as described above.

[0127] More specifically, as shown in Figures 8 and 9a, the rotating connecting portion 420 is formed on the rotating surface 411 that contacts the rotating plate 430. Here, the rotating connecting portion 420 includes a connecting frame 421 and a rotating groove portion 422.

[0128] The connecting frame 421 protrudes from the rotating surface 411 to have a circular frame shape, and the rotating groove portion 422 is formed in an arc shape along the circumference of the connecting frame 421 so as to be adjacent to the connecting frame 421. Here, the rotating groove portion 422 is formed along the circumference of the connecting frame 421, for example, in a quarter-circle arc. As a result, the faucet portion 400 can rotate within a range of 90 degrees, which is the range of the quarter-circle arc.

[0129] Furthermore, as shown in Figures 8, 9b, and 9c, the rotating plate 430 has a predetermined plate shape and is positioned in contact with the rotating surface 411. Here, as mentioned above, the rotating plate 430 is fixed on the main body 100 and its position does not change.

[0130] Here, the upper surface (Figure 9b) of the rotating plate 430 is in contact with the rotating connecting portion 420 formed on the rotating surface 411, and the lower surface (Figure 9c) is the opposite surface that is connected to the rotating connecting portion 420 and is in contact with the fixed plate 440, which will be described later.

[0131] First, as shown in Figure 9b, an opening 431 is formed on the upper surface of the rotating plate 430 at a position aligned with the connecting frame 421, and a guide projection 432 is provided adjacent to the opening 431. As a result, the guide projection 432 is positioned to be inserted into the rotating groove 422.

[0132] Furthermore, the faucet body 410 is guided to rotate by the guide projection 432 and the rotating groove 421, and can rotate within a 90-degree arc range in which the rotating groove 421 is formed.

[0133] On the other hand, as shown in Figure 9c, a guide block 433 and a pair of first and second fixing parts 434 and 435 are formed on the lower surface of the rotating plate 430 adjacent to the opening 431. Here, the guide block 433 extends projecting along the arc of the opening 431 over a range of 180 degrees, which is a half-circle arc, and the first and second fixing parts 434 and 435 are provided projecting from both ends of the guide block 433 at a predetermined distance.

[0134] Furthermore, as shown in Figures 8, 9c, and 9d, the fixing plate 440 rotates relative to the rotating plate 430 while being fixed to the faucet body 410.

[0135] As shown in Figure 9d, the fixed plate 440 has a fastening block 441 and first and second fastening portions 442 and 443 that protrude from the surface facing the rotating plate 430. Here, the fastening block 441 and the first and second fastening portions 442 and 443 limit the range of rotation of the faucet body 410 and the rotating plate 430.

[0136] In other words, the fastening block 441 has a half-circle shape, that is, a shape like a guide frame that protrudes in a 90-degree range, and is connected to the aforementioned guide block 433 in contact with each other. Therefore, when the fixed plate 440 rotates relative to the rotating plate 430, the direction of the rotation is guided by the guide block 433 and the fastening block 441.

[0137] Furthermore, the first and second fastening portions 442 and 443 have a shape that protrudes from both ends of the fastening block 441 toward the center, and serve as stoppers. That is, the first and second fastening blocks 442 and 443 contact either of the first and second fixing portions 434 and 435 described above, thereby restricting the relative rotation of the fixing plate 440 with respect to the rotating plate 430.

[0138] For example, if the fastening block 441 rotates in one direction and the first fastening portion 442 comes into contact with the first fixing portion 434, further rotation in that direction can be restricted. Conversely, if the fastening block 441 rotates in another direction and the second fastening portion 443 comes into contact with the second fixing portion 435, further rotation in that direction can be restricted.

[0139] In this case, the guide block 433 extends in a 1 / 2 arc, i.e., a range of 180 degrees, and the fastening block 441 extends in a 1 / 4 arc, i.e., a range of 90 degrees, so that one of the first and second fastening portions 442, 443 is restricted from rotating in a particular direction by one of the first and second fixing portions 434, 435. Of course, depending on the design, the guide block 433 could also extend in a 1 / 4 arc, so that each of the first and second fastening portions 442, 443 is restricted from rotating in both directions by each of the first and second fixing portions 434, 435.

[0140] By limiting the range of rotation in this way, the user can perceive the degree of rotation of the faucet body 410, i.e., the range of rotation, and will not apply unnecessary external force to force the rotation of the faucet body 410, thereby minimizing damage to the faucet part 400 during the rotation process.

[0141] Figures 10a to 10c are perspective views showing the water purifier compatibility method in Figure 1a. Figure 11 is a perspective view showing the compatible unit in Figure 10b.

[0142] In the case of the water purifier 10 shown in Figure 1a, the faucet portion 400 is fixed together with the fixing unit 300 on the upper surface 140 of the main body portion 100, and in this fixed state, the water purifier 10 can be used as a tabletop water purifier. That is, the water purifier 10 shown in Figure 1a is used in a form that is installed on the top surface of a sink or various other tables to provide purified water to the user.

[0143] Here, the faucet portion 400 and the fixing unit 300 can be removed together from the upper surface 140, as will be described later. When the faucet portion 400 and the fixing unit 300 are removed together from the upper surface 140 in this way, the interchangeable unit 600 can be mounted on the upper surface 140, as shown in Figure 10b.

[0144] In other words, the interchangeable unit 600 has a rectangular block shape as a whole and has the same size as the overall surface size of the upper surface 140. As a result, the interchangeable unit 600 can be directly attached to the detached positions of the faucet portion 400 and the fixing unit 300.

[0145] The interchangeable unit 600 does not include a water outlet that dispenses purified water directly to the user, like the faucet unit 400, and includes a connecting unit 601 that is formed upward. Here, the position of the connecting unit 601 can vary in various ways and is not limited to the upward direction, but can also be formed in the lateral direction of the interchangeable unit 600.

[0146] Although not shown in the figures, the connecting unit 601 can be fitted with additional external piping, which can extend to a water outlet where purified water is ultimately dispensed. Thus, the water purifier 11 in Figure 10b, with the interchangeable unit 600 fitted, can be used as a built-in water purifier. That is, the water purifier 11 in Figure 10b can be installed inside a sink or the like, and the additional piping connected to the connecting unit 601 can be connected to another water outlet exposed on the outside of the sink, thereby providing purified water to the water outlet.

[0147] Furthermore, the water purifier according to this embodiment can be selectively used as a tabletop water purifier 10 as shown in Figure 1a, or as a built-in water purifier 11 as shown in Figure 10b, by selectively attaching the faucet section 400, the fixed unit 300, and the interchangeable unit 600.

[0148] Based on the structure of the water purifier 10 as shown in Figure 1a, and with further reference to Figures 10a to 10c, a method for interchangeable installation of the water purifier 10, that is, a method for interchangeably installing the faucet section 400, the fixed unit 300, and the interchangeable unit 600 in the water purifier 10, will be described.

[0149] First, as shown in Figure 1a, when the water purifier 10 is used as a tabletop water purifier, the user can extract and use purified water through the water outlet 430 on the second surface 120 side.

[0150] To switch from the tabletop water purifier 10 to the built-in water purifier 11, the operations shown in Figures 1b and 1c must first be performed. Since the operation is as described above, a redundant explanation will be omitted.

[0151] As shown in Figure 10a, and as described in Figure 1c above, a predetermined clearance 101 is created, which exposes the upper surface 140 of the main body 100 through the space between the fixed unit 300 and the faucet part 400. Here, the clearance 101 exposes the connecting frame 190 and the connecting part 195 to the outside.

[0152] The connecting frame 190 extends in the second direction (Y) and is a frame structure that fixes the faucet portion 400 and the fixing unit 300, and is coupled to the upper surface 140. That is, the faucet portion 400 is coupled to one side of the connecting frame 190, and the fixing unit 300 is coupled to the other side of the connecting frame 190. Here, as shown in Figure 3, a predetermined fastening guide 333 is formed on the sliding surface 312 of the fixing unit 300 and is coupled to the connecting frame 190.

[0153] As described above, with the fixing unit 300 and the faucet portion 400 connected on the connecting frame 190, the connecting frame 190 is fixed to the upper surface 140 of the main body portion 100 by the connecting portion 195.

[0154] In other words, when the coupling portion 195 exposed to the outside through the play space 101 is released, the fixing unit 300 and the faucet portion 400 are also released from the upper surface 140, thereby allowing the fixing unit 300 and the faucet portion 400 to be removed from the main body portion 100.

[0155] Thus, by releasing the coupling of the coupling portion 195, the fixing unit 300 and the faucet portion 400 are removed from the main body portion 100.

[0156] Next, as shown in Figure 10b, the interchangeable unit 600 is attached to the upper surface 140 of the main body 100. Although not shown in detail here, another connecting unit may be provided on the lower surface of the interchangeable unit 600, which can slide and be fixed to the upper surface 140 of the main body 100, and such a connecting method is not particularly limited.

[0157] Subsequently, as shown in Figure 10c, the rotating part 210 is switched back to the position shown in Figure 1a in order to fix the position of the interchangeable unit 600 coupled to the upper surface 140 of the main body 100. That is, the rotating part 210 is rotated again, for example, counterclockwise, as indicated by the arrow. Thus, although not shown in the figures, the rotating bar 230 connected to the rotating part 210 also changes position and is coupled to the second fixing groove 623 of the second fixing guide 622 formed on the bottom surface of the interchangeable unit 600, which will be described later.

[0158] In addition, the compatible unit 600 is stably fixed in place on the upper surface 140 of the main body 100, as shown in Figure 10c. Furthermore, with the compatible unit 600 connected, as shown in Figure 10c, the connecting unit 601 is positioned facing upwards, and the water purifier 11 can be used as a built-in water purifier.

[0159] On the other hand, by performing the steps described above in reverse, the interchangeable unit 600 can be removed from the main body 100, and the faucet 400 and the fixing unit 300 can be attached to the main body 100.

[0160] Therefore, the user can switch between using the tabletop water purifier 10 and the built-in water purifier 11 at any time as needed by simply connecting and disconnecting them as described above, thereby improving ease of use.

[0161] On the other hand, the state in which the fixed unit 300 is released before the compatible unit 600 is coupled is as described above with reference to Figure 3. As a result, when the compatible unit 600 is coupled, the compatible unit 600 is coupled to the rotating bar 230.

[0162] More specifically, as shown in Figure 11, in the compatible unit 600 as well, a second fixing block 620 is formed on the bottom surface 612 of the compatible body 610, which is a square block shape, and the rotating bar 230 is selectively coupled to the second fixing block 620.

[0163] Here, the first fixing block 320 formed on the fixing unit 300 and the second fixing block 620 formed on the interchangeable unit 600 are substantially identical in structure, and are connected by the rotating unit 200 in the same manner. That is, the second fixing block 620 also includes a second fixing frame 621 having the same shape as the first fixing frame 321, and a second fixing guide 622 having the same shape as the first fixing guide 322. Furthermore, the second fixing groove 623 has the same shape as the first fixing groove 323.

[0164] In addition, the second fixed block 620 can be connected to the rotating unit 200, similar to the connection between the first fixed block 320 and the rotating unit 200 described above, and a redundant explanation regarding this will be omitted. Similarly, the second fixed block 620 can be disconnected from the rotating unit 200, and a redundant explanation regarding this will also be omitted.

[0165] As described above, the relatively easy connection and disconnection allows the user to selectively switch between using the tabletop water purifier 10 and the built-in water purifier 11.

[0166] According to the embodiments of the present invention described above, the faucet can be rotated to a first position and a second position, allowing its position to be changed to suit the installation environment, thereby improving space utilization and user convenience. In the first and second positions, the faucet is fixed by a fixing unit, thus enabling more stable fixing.

[0167] In contrast, if the fixed unit forms a predetermined play space through simple sliding movement, the faucet portion becomes rotatable, and the position of the faucet portion can be easily changed by rotation. In particular, the fixed state or the sliding state due to the release of the fixed unit is realized by the operation of the rotating unit, which can be easily done by the user rotating a lever from the outside. Therefore, an ordinary user who is not a specialist can simply operate the lever, which is the rotating part, to switch between the fixed state and the sliding state of the fixed unit, thereby improving user convenience and operability.

[0168] Specifically, the coupling and uncoupling are achieved by coupling and uncoupling a first fixing block formed on the bottom surface of the fixing unit with a rotating bar included in the rotating unit. This offers the advantages of being easy to design and manufacture, having stable and easy operation, and being manufactured to have sufficient durability.

[0169] In particular, by guiding the variable position of the rotating bar through the guide surface of the support block, the coupling and uncoupling between the rotating bar and the first fixed block can be performed more stably.

[0170] On the other hand, by guiding the sliding of the fixed unit with the guide unit, it is possible to guide the sliding only to a predetermined sliding direction and position, and to stably fix and release the faucet portion and the fixed unit. In other words, the sliding direction of the fixed unit is stably guided by the central guide portion of the guide unit and the central protrusion portion of the fixed unit, and the sliding range of the fixed unit can be stably set through the first and second guide portions of the guide unit and the first and second sliding portions of the fixed unit.

[0171] Furthermore, the faucet section is guided in the direction of rotation by the rotating plate and the fixed plate, and the range of rotation is also limited. This allows the user to rotate the faucet section within the limited range in both direction and degree of rotation, thereby minimizing damage to the faucet section caused by unnecessary rotation.

[0172] Furthermore, by selectively connecting the faucet section and the compatible unit to the main body, it is possible to selectively use it as a tabletop water purifier or a built-in water purifier. This allows for the installation of a water purifier that is more suitable for various usage environments, improving not only usability and convenience but also space utilization.

[0173] Furthermore, since the faucet and the interchangeable unit can be easily attached and detached by releasing the fastening, even ordinary users who are not experts can perform the work themselves, thereby improving user convenience.

[0174] Here, the fixing unit that secures the position of the faucet is moved by sliding, creating a play space between it and the faucet, and the fastening part is released while exposed to the outside through the play space. Therefore, the fastening part can be easily released by the simple sliding motion of the fixing unit.

[0175] In particular, the state in which the fixed unit is slidable or the state in which the faucet is fixed is achieved by the operation of the rotating unit, and can be easily performed by the user from the outside by rotating the lever. Similarly, the interchangeable unit can also be fixed to the main body by rotating the lever.

[0176] Therefore, ordinary users who are not experts can simply operate the lever, which is a rotating part, to switch between the fixed state and the sliding state of the fixed unit, and to switch between the fixed state and the unlocked state of the interchangeable unit, thereby improving user convenience and operability.

[0177] Specifically, the connection and disconnection of the fixed unit and the interchangeable unit are achieved by connecting and disconnecting the fixed blocks formed on the bottom surfaces of the fixed unit and the interchangeable unit with the rotating bar included in the rotating unit. This design and manufacturing process is simple, provides stable and easy operation, and offers the advantage of sufficient durability.

[0178] While preferred embodiments of the present invention have been described above with reference to those skilled in the art, a person skilled in the art will understand that the present invention can be modified and altered in various ways without departing from the spirit and scope of the invention as set forth in the following claims.
