Description

Susan

[0001] The present invention relates to a water supply.

[0002] A faucet is a device designed to supply water to a user; when a user operates the faucet, stored water or raw water supplied from an external source can be delivered to the user through the faucet's outlet. Such faucets can be used in bathrooms or kitchens.

[0003] The faucet can supply cold water and hot water from the raw water supplied from an external source to the user. The faucet can provide either cold water or hot water, or a mixed water mixture of cold water and hot water to the user. A knob is provided on the faucet for the use of the mixed water, and the user can adjust the temperature of the mixed water by rotating the knob.

[0004] As such, faucets can provide hot water to users, but there is a risk that the user may suffer burns from the hot water. In particular, infants who are unfamiliar with operating the knobs on faucets may suffer burns if they carelessly turn them. To prevent such accidents, various types of safety devices for faucets are being developed.

[0005] For example, U.S. Patent US6772453B2 (Priority Patent 1), U.S. Patent US9534703B2 (Prior Patent 2), and Korean Patent 10-1554547 (Prior Patent 3) propose a separate safety device that is coupled to a faucet. However, since Prior Patents 1 to 3 use a method of coupling a separate safety device to a faucet, there is a problem that it is inconvenient to use and the aesthetic appeal of the faucet is also reduced.

[0006] Meanwhile, Korean Patent Publication 10-2015-0031676 (Prior Patent 4) and U.S. Patent US9422145B2 (Prior Patent 5) disclose a technology in which a safety pin (safety button) is integrally provided with the faucet, and hot water is provided only when the user first operates the safety pin (safety button). However, prior patents 4 and 5 have poor operability of the faucet because the user must first accurately press the safety pin (safety button) with a finger before operating the lever. Furthermore, since the safety pin (safety button) is installed on the lever in a structure that allows it to be pressed, water or foreign substances can easily enter through the gap between the safety pin (safety button) and the lever body, and such water or foreign substances also pose a problem of reducing the hygiene of the faucet. In addition, there is a disadvantage that the aesthetic appeal of the faucet is reduced due to the safety pin (safety button) protruding outward.

[0007] The present invention is intended to solve the problems of the prior art as described above. The objective of the present invention is to limit the rotational range of a control knob for temperature control, but to release the limitation of the rotational range when the user pushes or pulls the control knob.

[0008] Another objective of the present invention is to allow the entire control knob to move axially when a user pushes or pulls the control knob, thereby enabling intuitive and easy operation of the control knob.

[0009] Another objective of the present invention is to enable the limited state of the rotation range to be released by pushing or pulling the adjustment knob itself, without providing a separate button structure or the like to increase the rotation range of the adjustment knob.

[0010] Another objective of the present invention is to allow moisture inside the control knob to be discharged to the outside during the process of pushing the control knob.

[0011] According to a feature of the present invention for achieving the above-mentioned purpose, the present invention may include a temperature controller disposed in a casing and controlling the mixed flow rate of hot water and cold water through rotation. A control knob protruding from the casing may rotate the temperature controller while rotating relative to the casing around a knob axis. At this time, the control knob may have a first operating position in which rotation is permitted by a first angular range around the knob axis, and a second operating position in which movement is made in the axial direction of the knob axis from the first operating position and further rotation is permitted by a second angular range around the knob axis from one end of the first angular range. In this way, when the control knob is operated in a direction different from the rotation direction, the limitation on the rotation range is released, thereby improving both the safety and convenience of the faucet.

[0012] In addition, when the adjustment knob is moved from the first operating position to the second operating position, the axial distance between the adjustment knob and the casing may change. This unlocking mechanism can enhance user convenience.

[0013] In addition, the first angle range and the second angle range can form a continuous path along the rotational direction of the control knob. Accordingly, the user can continuously adjust the water temperature without interruption even after unlocking.

[0014] Additionally, a rotary coupler connecting the control knob and the temperature controller may be disposed between the control knob and the temperature controller. An operating space may be formed between the knob body of the control knob and the rotary coupler. When the knob body moves along the axial direction, the volume of the operating space may vary. When the volume changes in this way, the pressure inside the operating space increases, allowing moisture inside the operating space to be naturally discharged.

[0015] Additionally, the rotary coupler can be rotated by the control knob. The rotary coupler can guide the axial movement of the control knob while maintaining a fixed position relative to the axial direction. In this way, the rotary coupler can guide the axial movement while simultaneously transmitting the rotational force of the control knob to the temperature controller.

[0016] Additionally, the adjustment knob is provided with an elastic member, and the elastic member can provide elastic force to the adjustment knob in a direction from the second operating position toward the first operating position. The elastic member can automatically move the adjustment knob to the first operating position.

[0017] Additionally, the adjustment knob may be positioned closer to the casing and the axial direction at the second operating position than at the first operating position. Accordingly, the user can release the restricted state by pressing the adjustment knob.

[0018] Additionally, the casing or the control knob may be provided with a rotation limiting member protruding in the axial direction. When the control knob is in the first operating position, the rotation limiting member may interfere with the control knob or the casing at the end of the first angle range to limit the rotation of the control knob. When the control knob is in the second operating position, the interference between the rotation limiting member and the control knob or the casing at the end of the first angle range may be released. Accordingly, the user can continuously implement unlock and temperature increase functions through a rotation-press-rotation operation.

[0019] Additionally, the casing may be provided with a rotation limiting part that interferes with the adjustment knob of the first operating position and the end of the first angle range. The rotation limiting part may be released from interference with the adjustment knob of the second operating position and the end of the first angle range. In this way, the rotation limiting part may not be provided as a separate part but may be formed integrally with the casing.

[0020] Additionally, the casing may be provided with a rotation limiting part that limits the rotation of the adjustment knob at the end of the first angle range. The rotation limiting part may protrude in the axial direction from the casing.

[0021] Additionally, an adjustment slot guiding the rotation limiting part may be formed in the adjustment knob. The first angle range and the second angle range may be formed in the adjustment slot. In this way, the adjustment slot for angle adjustment may be integrally formed with the adjustment knob.

[0022] Additionally, the adjustment slot may include a first surface spaced apart from the knob axis by a first distance along the radial direction. The adjustment slot may have a second surface spaced apart from the first surface with respect to the axial direction and spaced apart from the knob axis by a second distance closer than the first distance along the radial direction.

[0023] Additionally, the adjustment knob may include a first adjustment slot forming the first angle range and a second adjustment slot connected to the first adjustment slot and forming the second angle range. The casing may be provided with a rotation limiting part that interferes with one end of the first adjustment slot at the first operating position. The interference between the rotation limiting part and one end of the first adjustment slot at the second operating position may be released.

[0024] Additionally, a stepped portion may be provided between the first adjustment slot and the second adjustment slot. In the first operating position, the locking end of the rotation limiting portion may interfere with the stepped portion. In the second operating position, the locking end of the rotation limiting portion may be moved to a position away from the stepped portion.

[0025] Additionally, the rotary coupler can maintain a fixed state with respect to the axial direction of the knob axis. The knob body can be guided by the rotary coupler and moved along the axial direction between the first operating position and the second operating position.

[0026] Additionally, the rotary coupler can be positioned in an operating space formed inside the knob body. Accordingly, the rotary coupler can be configured so as not to be exposed to the outside.

[0027] Additionally, the knob body may include a knob cover having a mounting space formed therein, and a knob core disposed in the mounting space, operating together with the knob cover, and having its axial movement guided by the rotary coupler.

[0028] Additionally, a rotation limiting part may protrude in the axial direction from the casing. When the adjustment knob is rotated at the first operating position, the knob core may interfere with the rotation limiting part at the end of the first angle range.

[0029] Additionally, the knob core may be formed with a first adjustment slot forming the first angle range and a second adjustment slot connected to the first adjustment slot and forming the second angle range. Accordingly, the knob core handles the relatively complex shape, and the knob cover implements a simple form to enhance aesthetic appeal.

[0030] In addition, the first adjustment slot and the second adjustment slot may form a continuous arc shape along the rotational direction of the adjustment knob. The end portion of the first adjustment slot may interfere with a rotation limiting portion provided in the casing.

[0031] Additionally, an elastic member is disposed between the knob body and the rotary coupler, and the elastic member can provide elastic force to the knob body in a direction away from the rotary coupler in the axial direction. That is, the rotary coupler can provide an installation space for the elastic member.

[0032] In addition, the knob body can be guided by the rotary coupler and moved linearly in the axial direction. The rotary coupler may be equipped with a stopper that limits the axial movement distance of the knob body. In this way, the rotary coupler can also limit the axial movement range of the knob body.

[0033] Additionally, the temperature controller may be provided with a knob holder. The knob holder and the control knob may be coupled to each other in the axial direction. The control knob may be coupled to the knob holder and indirectly connected to the temperature controller.

[0034] In addition, the knob holder can form the knob axis that becomes the rotation center of the adjustment knob.

[0035] Additionally, the adjustment knob and the knob holder may be provided with a knob fastening part and a holder fastening part that are coupled to each other in an axial direction. The knob fastening part and the holder fastening part may each extend along the radial direction of the knob axis.

[0036] Additionally, the casing may be provided with a rotation limiting portion protruding in the axial direction from the edge of the knob holder. The rotation limiting portion may interfere with the adjustment knob at the end of the first angle range.

[0037] In addition, the knob cover can be coupled with the knob core to restrict the axial movement of the knob core and the independent rotation of the knob core, respectively. Accordingly, relative rotation between the parts constituting the knob body can be restricted without the need for a separate fastener.

[0038] Additionally, an indicator protruding from the surface of the adjustment knob may be coupled to the adjustment knob. The indicator may be coupled to the adjustment knob in the axial direction. The indicator may engage the knob cover and the knob core, respectively, to limit the relative rotation of the knob cover and the knob core. In this way, the indicator not only allows the user to perceive the rotation angle of the adjustment knob but also serves to secure multiple parts together.

[0039] Additionally, a gap may be formed between the knob cover and the knob core. The gap may be opened in the axial direction toward the surface of the casing. Through this, moisture in the gap may be discharged to the outside.

[0040] Additionally, a rotary coupler connecting the control knob and the temperature controller may be disposed between the control knob and the temperature controller. An operating space may be formed between the knob body and the rotary coupler. The gap space may be connected to the operating space. Accordingly, moisture in the gap space may also be discharged through the pressure change generated when the control knob is pressed.

[0041] Additionally, the knob cover may surround the outer surface of the knob core, and the knob core may surround the outer surface of the rotary coupler. Accordingly, only the knob cover is exposed to the outside, and a unified aesthetic can be provided.

[0042] Additionally, the adjustment knob may move along the axial direction of the knob axis to have multiple axial positions. The adjustment knob may rotate around the knob axis by different angular ranges at the multiple positions. Accordingly, the user can set various rotational angle ranges of the adjustment knob through a push / pull action.

[0043] Additionally, the control knob may be coupled to the temperature controller in the axial direction of the rotation axis. The control knob may be rotated to form a first distance from the surface of the casing with respect to the axial direction, or the control knob may be rotated to form a second distance from the surface of the casing that is closer than the first distance with respect to the axial direction.

[0044] The faucet according to the present invention, as examined above, has the following effects.

[0045] The faucet of the present invention limits the rotational range of the control knob for temperature control under normal conditions, thereby reducing the risk of injury such as burns. At the same time, if the control knob is operated in a direction different from the rotational direction, the limitation on the rotational range is released, allowing the temperature of the discharged water to be raised above the limited range. Therefore, there is an effect of improving both the safety and convenience of the faucet.

[0046] In addition, in the present invention, the rotation range limitation of the control knob can be released when the entire control knob moves in the axial direction. When a user wishes to expand the temperature control range of the faucet, they simply need to move the entire control knob in the axial direction. Accordingly, the operability of the faucet is improved, and the user can use the faucet more intuitively, thereby increasing user friendliness.

[0047] In particular, in the present invention, there is no need to precisely press a safety button or the like with a finger to expand the temperature control range; instead, the user can expand the temperature control range by pressing the entire front surface of the control lever, thereby ensuring a large operating area. Consequently, operability for operating the control lever of the faucet is improved.

[0048] Furthermore, the faucet according to the present invention does not have separate components, such as a safety button or safety lever, for releasing the rotation range limitation of the control lever. Since there are no separate components that operate independently of the rotation of the control lever, the structure of the control lever can be simplified. In addition, since there is no need to provide space for separate components, such as a safety button, to operate, the possibility of moisture or foreign substances entering is reduced. Therefore, it also has the effect of preventing a decrease in hygiene caused by the accumulation of moisture or foreign substances.

[0049] Furthermore, in the present invention, during the process of the control knob operating in the axial direction (pressing / pulling), the volume of the operating space formed between the knob body constituting the control knob and the rotary coupler changes. When the volume changes in this way, the pressure inside the operating space increases, allowing moisture inside the operating space to be naturally discharged. Therefore, even if the faucet is used in an environment constantly exposed to moisture, such as a bathroom, it is possible to prevent moisture from accumulating inside the control knob.

[0050] In addition, the gap between the knob cover and the knob core constituting the control knob is also connected to the operating space, so pressure can increase during the operation of the control knob. Therefore, even if moisture enters between the knob cover and the knob core, it can be discharged during the use of the control knob, thereby enhancing the hygiene of the control knob.

[0051] Furthermore, in the present invention, the structure for limiting the rotation angle range of the control knob may be composed of a control slot and a rotation limiting part. Here, the control slot may be formed integrally with the control lever, and the rotation limiting part may be formed integrally with the casing. Therefore, in the present invention, the rotation angle of the control knob can be limited without adding separate parts.

[0052] In addition, since the control knob of the present invention does not have a separate safety button, the control knob can provide an integrated aesthetic. In particular, since it is not necessary to add a separate button or the like to the control knob, there is also an advantage of increasing the design freedom of the control knob.

[0053] Additionally, the control knob of the present invention may be coupled with an indicator that protrudes from the surface of the control knob and recognizes the rotational state of the control knob. When the indicator is coupled to the control knob, the indicator can engage the knob cover and the knob core constituting the control knob, respectively, thereby limiting their relative rotation. In this way, the indicator of the present invention not only allows the user to recognize the rotational angle of the control knob but also reduces the number of parts of the control knob and simplifies the structure by coupling multiple parts together.

[0087] Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions would hinder understanding of the embodiments of the present invention, such detailed description is omitted.

[0088] The present invention relates to a faucet (10). The faucet (10) of the present invention can provide raw water supplied from an external water source by treating it in various ways. The faucet (10) may include faucets used in bathrooms, such as shower faucets, and faucets used in kitchens, such as sink faucets. Additionally, the faucet (10) may be used outdoors in addition to indoors. The faucet (10) may also be applied to home appliances that supply water, such as water purifiers.

[0089] Here, raw water is water supplied from the outside and may be tap water. More specifically, the raw water may include cold water and hot water. The cold water is raw water in an unheated state, and the hot water is raw water supplied after being heated through a boiler, etc. For reference, in the following description, raw water refers to cold water and hot water introduced from the outside, mixed water refers to water in which cold water and hot water are mixed with each other by a temperature controller (140), controlled water refers to water whose flow rate is controlled by a flow rate controller (150), and purified water refers to water from which impurities have been filtered by a filter (160).

[0090] The faucet (10) of the present invention may provide functions such as mixing cold water and hot water, purifying water, supplying power through a generator (170), transmitting information through a display (not shown), receiving / sending data through a communication means (not shown), automatic control through a control device, or dispensing water through a plurality of outlets. The communication means may include one or more of a Bluetooth communication module, a WiFi communication module, a Zigbee communication module, and an NFC communication module. The communication means may receive power through the generator (170).

[0091] The above temperature controller (140) can adjust the mixing ratio of cold water and hot water, and the user can control the temperature controller (140) by turning the control knob (300). In this embodiment, the control knob (300) is configured to rotate within a specific angle range. For example, the rotation range of the control knob (300) may be limited so that water at a temperature higher than the set temperature is not supplied. After changing the axial position of the control knob (300) by pushing or pulling the control knob (300), the user can turn the control knob (300) again to rotate the control knob (300) to an angle greater than the limited rotation range. Below, the structure of the control knob (300) for operating the temperature controller (140) will be described in detail.

[0092] For reference, in FIG. 1, F represents the front of the water tap (10) and R represents the rear of the water tap (10). Here, the front of the water tap (10) refers to the front of the water tap (10) far from the installation surface (W, see FIG. 2), and the rear of the water tap (10) refers to the side toward the installation surface (W).

[0093] Referring to FIG. 1, the above faucet (10) is shown being used as a bathroom faucet. In this embodiment, the above faucet (10) may include a plurality of outlets (outlet parts (OH1, OH2)). The above faucet (10) may include a first water outlet pipe (1) and a rainfall shower head (2) connected to the first water outlet pipe (1). The above shower may include a handheld shower head (4) connected to the second water outlet pipe (3). As another example, either the rainfall shower head (2) or the handheld shower head (4) may be omitted.

[0094] The above faucet (10) may be provided with a first outlet section (OH1) for discharging water downward from the faucet (10). When water is discharged downward from the faucet (10) through the first outlet section (OH1), the user can fill a bathtub (not shown) located at the bottom of the faucet (10) with water. As shown in FIG. 2, the above faucet (10) may be provided with a second outlet section (OH2) for discharging water to the rainfall shower head (2) or the hand shower head (4). The first discharge pipe (1) or the second discharge pipe (3) may be connected to the second outlet section (OH2). The user can discharge water to the first outlet section (OH1) or the second outlet section (OH2) by operating the water discharge selector (190) described below.

[0095] FIG. 1 illustrates a first control knob (300) of a temperature controller (140) for controlling the temperature of water. When the first control knob (300) is rotated, the temperature controller (140) operates to determine the mixing ratio of hot and cold water, or hot or cold water may be discharged without mixing. The faucet (10) may further include a second control knob (400) separate from the first control knob (300). The second control knob (400) is for operating a flow rate controller (150) to control the flow rate of the discharged water. When the second control knob (400) is rotated, the discharged flow rate can be controlled.

[0096] For reference, the first adjustment knob (300) and the second adjustment knob (400) can be operated in the same way. Below, a detailed description of the second adjustment knob (400) will be omitted, and the description will be based on the first adjustment knob (300). For convenience of explanation, the first adjustment knob (300) will be referred to as the adjustment knob below.

[0097] In addition to the above-mentioned control knob (300), the faucet (10) may be equipped with a water outlet selector (190). The water outlet selector (190) may allow the user to select which of the plurality of outlet sections (OH1, OH2) water will be discharged. In this embodiment, the water outlet selector (190) may have a first selection position that is pressed and a second selection position that is protruded in the opposite direction. For example, when the water outlet selector (190) is operated to the first selection position, water may be discharged through the first outlet section (OH1), and when operated to the second selection position, water may be discharged through the second outlet section (OH2). As another example, the water outlet selector (190) may operate in the opposite way. As yet another example, the outlet section (OH1, OH2) through which water is discharged may be selected by rotating the water outlet selector (190) rather than by pressing.

[0098] The above-mentioned water outlet selector (190) can be positioned between the two control knobs (300, 400). The two control knobs (300, 400) can be positioned at each end of the front of the faucet (10). In this way, the faucet (10) can provide a unified aesthetic to the user through a symmetrical structure.

[0099] Referring to FIG. 2, the above-mentioned faucet (10) is shown installed on a wall surface, which is the installation surface (W). As such, the rear surface of the above-mentioned faucet (10) faces the installation surface (W), and the above-mentioned faucet (10) can protrude from the installation surface (W). The above-mentioned faucet (10) can be fixed to the installation surface (W) through a wall-mount installation adapter (7). Accordingly, a large load due to the weight of the above-mentioned faucet (10) can be concentrated on the installation adapter (7). In this embodiment, as described below, the load applied to the installation adapter (7) can be reduced through the structure of the above-mentioned Euro guide unit (100), the arrangement of its parts, and the reinforcing plate (130). As another example, the above-mentioned faucet (10) can be stored in a storage compartment recessed in the wall. As yet another example, the lower part of the above-mentioned faucet (10) can be supported through an installation adapter (7) connected to the lower part of the above-mentioned faucet (10).

[0100] As shown in FIGS. 1 and 2, the lower part of the above-mentioned faucet (10) may have outlet sections (OH1, OH2) and a part of the filter (160) described later exposed. The user may grasp the exposed part of the filter (160) and detach and replace the filter section (163, shown in FIG. 6) constituting the filter (160). In this embodiment, the filter section (163) may be mounted / detachable in the vertical direction, and this structure will be explained again below.

[0101] Referring to FIG. 3, the handle (167) of the filter (160) described above may be exposed at the bottom of the faucet (10). The handle (167) may protrude downward from the filter (160). In this embodiment, the filter (160) may be attached to the faucet (10) by a screw fastening method. Thus, the user can rotate the handle (167) to detach the filter part (163) from the faucet (10) or attach it to the faucet (10). An additional mounting part (167a, shown in FIG. 10) may be formed inside the handle (167) to provide an additional filter (160), such as an antibacterial filter (160).

[0102] FIGS. 4 and FIGS. 5 illustrate the disassembled parts constituting the above-mentioned faucet (10). As can be seen here, the exterior and frame of the above-mentioned faucet (10) can be formed by a casing (20). The casing (20) may have a shape that is longer in the left-right direction than in the front-rear direction. Both sides of the casing (20) may have a curved shape. As another example, the casing (20) may be made in an overall angular shape without a curved structure.

[0103] The above casing (20) may have an installation space (21) formed inside. The installation space (21) is open in the front-rear direction, and an inner housing (30) may be placed in the installation space (21). The inner housing (30) may form the frame of the faucet (10) together with the casing (20). As another example, the inner housing (30) may be omitted or may be made integrally with the casing (20).

[0104] A discharge hole (25) may be opened in the casing (20). The discharge hole (25) may be formed by penetrating the bottom surface of the casing (20). The first outlet section (OH1) is connected to the water discharge selector (190), and when the water discharge selector (190) is placed in the installation space (21) of the casing (20), the first outlet section (OH1) may protrude downward through the discharge hole (25).

[0105] A filter hole (26) may be opened in the casing (20). The filter hole (26) may be spaced apart from the discharge hole (25) and may be formed by penetrating the bottom surface of the casing (20). In this embodiment, the filter (160) is assembled / disassembled in the vertical direction, and the filter (160) may be replaced through the filter hole (26). The handle (167) of the filter (160) may protrude downward through the filter hole (26).

[0106] The inner housing (30) may be placed inside the casing (20). The inner housing (30) shields the front of the casing (20), and one or more components constituting a water tap (10) may be mounted in the inner housing (30). The housing body (31) forming the frame of the inner housing (30) may be injection molded and may have a more complex shape than the casing (20).

[0107] As shown in FIG. 4, the housing body (31) constituting the inner housing (30) may be provided with a housing fastening part (32). The housing fastening part (32) may be combined with a Euro guide unit (100) to be described later, so that the inner housing (30) and the Euro guide unit (100) can be assembled together. Reference numeral 31a is an internal space defined by the housing body (31), where parts can be stored.

[0108] Referring to FIG. 5, the inner housing (30) may be provided with a selector mounting portion (34). The water outlet selector (190) is disposed in the selector mounting portion (34). The water outlet selector (190) is mounted on the selector mounting portion (34), and a part of the water outlet selector (190) protrudes forward from the selector mounting portion (34). Reference numeral 35 indicates a water outlet connection hole connected to a water outlet hole (25) formed on the bottom surface of the inner housing (30).

[0109] A filter connection hole (36) for replacing the filter (160) may be formed in the bottom portion of the inner housing (30). The filter connection hole (36) is connected to the filter hole (26) of the casing (20). The filter (160) that has passed through the filter connection hole (36) and the filter hole (26) may be placed inside the filter shell (39) provided in the inner housing (30). This structure will be described again below.

[0110] The inner housing (30) may be provided with a temperature control mounting part (37). The temperature control mounting part (37) supports the temperature controller (140) so that the temperature controller (140) can be stably fixed in the installation space (21). The temperature control mounting part (37) may extend rearward from the inner housing (30) to support the surface of the temperature controller (140). Referring to FIG. 19, the temperature control mounting part (37) may support the surface of the temperature controller (140) so that the temperature controller (140) does not move in the forward and backward directions.

[0111] Referring again to FIG. 5, the inner housing (30) may be provided with a filter shell (39). A filter (160) may be housed inside the filter shell (39). The filter shell (39) has a cylindrical shape corresponding to the filter (160), and the filter connection hole (36) is open at the bottom of the filter shell (39), so that the filter (160) can be attached to the filter shell (39) in an up-and-down direction.

[0112] The filter shell (39) may be provided with a filter inlet (39a) and a filter outlet (39b). The filter inlet (39a) and the filter outlet (39b) are connected to a flow guide unit (100) to be described below. The filter inlet (39a) receives raw water from the flow guide unit (100), and the filter outlet (39b) can supply purified water purified by the filter (160) back to the flow guide unit (100). To this end, the filter inlet (39a) and the filter outlet (39b) are each connected to a filter connector (FH) of the flow guide unit (100). This structure will be described again below.

[0113] As another example, the filter shell (39) may be configured separately from the inner housing (30). The filter shell (39) may form the housing of the filter (160) and may be installed together with the filter (160) in the installation space (21) or separated.

[0114] As shown in FIG. 5, the inner housing (30) may be provided with one or more spacer bars (SB). The spacer bars (SB) protrude from the front to the rear of the inner housing (30). The spacer bars (SB) support a plurality of components placed in the installation space (21), such as a generator (170), a temperature controller (140), a flow controller (150), etc., which will be described later. The plurality of components may be supported by the spacer bars (SB) toward the rear cover (50).

[0115] A front plate (40) may be disposed on the front of the inner housing (30). The front plate (40) constitutes the front of the inner housing (30). The front plate (40) may be coupled to the inner housing (30) or formed integrally with the inner housing (30). The front plate (40) may be made of a transparent or translucent material so as to project information displayed on a display (not shown) disposed inside the inner housing (30) forward.

[0116] Referring to FIG. 4, a pair of knob mounting holes (42, 43) are formed in the front plate (40). A pair of control knobs (300, 400) can be placed in each of the knob mounting holes (42, 43). Through the knob mounting holes (42, 43), the control knobs (300, 400) and the temperature controller (140) or the flow controller (150) can be connected to each other. Reference numeral 44 indicates a button mounting hole for mounting the water outlet selector (190).

[0117] A rotation limiting part (47) may be provided at the edge of the knob mounting hole (42, 43). The rotation limiting part (47) limits the rotation of the adjustment knob (300). More precisely, the rotation limiting part (47) limits the rotation range of the adjustment knob (300) so that the adjustment knob (300) rotates within a certain angle range. The rotation limiting part (47) may protrude in the axial direction of the adjustment knob (300) and may selectively interfere with the adjustment knob (300).

[0118] Referring to FIG. 19, the rotation limiting part (47) can be positioned closer to the rotation center (C, not shown in FIG. 19) of the control knob (300) than to the edge of the control knob (300) with respect to the radial direction. In this way, the rotation limiting part (47) is covered by the control knob (300) and is not exposed to the outside, and the aesthetic appeal of the faucet (10) can be avoided due to the rotation limiting part (47).

[0119] The rotation limiting part (47) may be provided at a position radially offset from the edge of the knob holder (360) to be described later. If the rotation limiting part (47) is radially offset from the edge of the knob holder (360) to be described later, it is possible to prevent the rotation of the knob holder (360) from being restricted by the rotation limiting part (47). The specific structure of such a rotation limiting part (47) will be explained again below together with the adjustment knob (300).

[0120] Referring again to FIG. 4, a rear cover (50) can be attached to the casing (20). The rear cover (50) can shield the rear of the installation space (21). The rear cover (50) is positioned on the opposite side of the front plate (40), with components such as the temperature controller (140) in between. Accordingly, components placed in the installation space (21) can be positioned between the rear cover (50) and the front plate (40). Reference numeral 52 indicates a cover body that forms the frame of the rear cover (50).

[0121] The rear cover (50) may be structured to protrude from the rear of the casing (20). The rear cover (50) may be integrally provided at the rear of the casing (20). The rear cover (50) may be provided with inlet guides (56a, 56b) for connection with inlet sections (IH1, IH2). The inlet guides (56a, 56b) may be configured as a pair for the inflow of hot and cold water. Referring to FIG. 4, cover inlet holes (53, 54) for connection with the inlet sections (IH1, IH2) are formed in the rear cover (50), and the cover inlet holes (53, 54) may be opened to the opposite side of the inlet guides (56a, 56b).

[0122] The rear cover (50) may be provided with an outlet nozzle (200) that constitutes the second outlet section (OH2). The outlet nozzle (200) allows water to be discharged through the second outlet section (OH2). The first discharge pipe (1) or the second discharge pipe (3) described above may be connected to the outlet nozzle (200). As the outlet nozzle (200) rotates, the direction of the discharge pipe (220) of the outlet nozzle (200) can be changed, thereby allowing the direction of the second outlet section (OH2) to be varied. Referring to FIG. 18, the connecting pipe (210) of the outlet nozzle (200) is connected to the water discharge selector (190), and the discharge pipe (220) connected to the connecting pipe (210) extends in a direction orthogonal to it to form the second outlet section (OH2). For reference, in FIG. 4, reference numeral 250 indicates the inlet side of the outlet nozzle (200) formed on the opposite side of the discharge pipe (220).

[0123] Referring to FIG. 5, the Euro guide unit (100) is positioned in front of the rear cover (50). A plurality of flow paths are formed inside the Euro guide unit (100). These plurality of flow paths can deliver or receive water to the temperature controller (140), the flow controller (150), the filter (160), the generator (170), and the water outlet selector (190). In this embodiment, the Euro guide unit (100) is responsible for the water delivery path. Of course, water also flows inside the temperature controller (140), the flow controller (150), the filter (160), the generator (170), and the water outlet selector (190), but the role of delivering water between these components is performed by the Euro guide unit (100).

[0124] The above-mentioned Euro guide unit (100) may be positioned within the installation space (21) at a location offset from the front plate (40) and the rear cover (50). The above-mentioned Euro guide unit (100) may be positioned further from the front plate (40) than the temperature controller (140), the flow controller (150), the filter (160), the generator (170), and the water outlet selector (190). In this way, if the above-mentioned Euro guide unit (100) is positioned close to the installation surface (W), the bending moment applied to the installation adapter (7) by the weight of the above-mentioned Euro guide unit (100) can be reduced.

[0125] The above-mentioned Euro guide unit (100) can be erected at the rear of the installation space (21). Here, being erected means that the upper and lower ends of the Euro guide unit (100), which have a width greater than the thickness of the Euro guide unit (100) based on the front-rear direction, are positioned in the height direction. In other words, the Euro body (110, 120) forming the frame of the Euro guide unit (100) is composed of a first Euro body (110) and a second Euro body (120), and the Euro guide unit (100) is positioned in the installation space (21) such that the direction in which they are joined together is the front-rear direction.

[0126] In another embodiment, the Euro guide unit (100) may be positioned at the top or bottom of the installation space (21). That is, the Euro guide unit (100) may be positioned horizontally at the top of the installation space (21) or horizontally at the bottom.

[0127] The above-described Euro guide unit (100) may be provided with a plurality of inlet sections (IH1, IH2). The inlet sections (IH1, IH2) are for supplying raw water. The plurality of inlet sections (IH1, IH2) are connected to the flow paths inside the Euro guide unit (100). The plurality of inlet sections (IH1, IH2) may be formed at the front and rear of the Euro guide unit (100). In this embodiment, the plurality of inlet sections (IH1, IH2) are opened at the rear of the Euro guide unit (100). The inlet sections (IH1, IH2) may be connected to a supply pipe (not shown) embedded in the installation surface (W) through the inlet guide (56a, 56b). Among the above inlet sections (IH1, IH2), cold water may be supplied to the first inlet section (IH1) and hot water may be supplied to the second inlet section (IH2). Alternatively, conversely, hot water may be supplied to the first inlet section (IH1) and cold water may be supplied to the second inlet section (IH2).

[0128] Drawing symbols SH1 and SH2 represent service holes, which are holes for injecting cleaning water for cleaning the Euro guide unit (100). The service holes (SH1, SH2) can be connected to cover service holes (57a, 57b, shown in FIG. 4) formed in the rear cover (50).

[0129] A reinforcing plate (130) may be attached to the above-mentioned Euro guide unit (100). The reinforcing plate (130) can reinforce the strength of the above-mentioned Euro guide unit (100). When the above-mentioned Euro guide unit (100) is connected to the above-mentioned installation adapter (7), a bending moment caused by the weight of the entire faucet (10) together with the above-mentioned installation adapter (7) may be concentrated on the above-mentioned Euro guide unit (100). Accordingly, the above-mentioned Euro guide unit (100) may be damaged or displaced from the installation position. The reinforcing plate (130) can prevent such damage or displacement of the above-mentioned Euro guide unit (100). Referring to FIG. 13, the above-mentioned Euro guide unit (100) is provided with plate assembly holes (116, 126) for assembling the reinforcing plate (130).

[0130] Specifically, the reinforcing plate (130) may have a flat plate structure. The reinforcing plate (130) may be made of a high-strength metal material. The reinforcing plate (130) may be in surface contact with the surface of the flow guide unit (100). The reinforcing plate (130) may be coupled to the first flow body (110) in a state of surface contact with the surface of the first flow body (110) of the flow guide unit (100). The installation adapter (7) may be coupled to the reinforcing plate (130). Accordingly, the installation adapter (7) may not be directly coupled to the flow guide unit (100), but may be coupled indirectly through the reinforcing plate (130). In this embodiment, the reinforcing plate (130) is assembled to the flow guide unit (100) by a plate fastener (B1). As another example, the reinforcing plate (130) may be omitted or embedded in the Euro guide unit (100) or the rear cover (50).

[0131] A pair of plate holes (133, 134) for connecting the inlet guide (56a, 56b) and the Euro guide unit (100) may be opened in the reinforcing plate (130). Among the pair of plate holes (133, 134), the first plate hole (133) may be a part into which cold water flows. Among the pair of plate holes (133, 134), the second plate hole (134) may be a part into which hot water flows. Reference numerals 137a and 137b indicate holes for exposing the service holes (SH1, SH2) to the rear.

[0132] Referring to FIGS. 6 and 7, a temperature controller (140), a flow controller (150), a filter (160), a generator (170), a transfer pipe (180), and an outlet selector (190) may be arranged in front of the Euro guide unit (100). The temperature controller (140), the flow controller (150), the filter (160), the generator (170), the transfer pipe (180), and the outlet selector (190) may be arranged in the left and right directions. More precisely, the Euro guide unit (100), the temperature controller (140), the flow controller (150), the filter (160), the generator (170), the transfer pipe (180), and the water outlet selector (190) are arranged in the front-rear direction, while the temperature controller (140), the flow controller (150), the filter (160), the generator (170), the transfer pipe (180), and the water outlet selector (190) are arranged in the left-right direction relative to each other. As another example, some or all of the temperature controller (140), the flow controller (150), the filter (160), the generator (170), the transfer pipe (180), and the water outlet selector (190) may be arranged in the up-down direction.

[0133] The above temperature controller (140), flow controller (150), filter (160), generator (170), transfer pipe (180), and water outlet selector (190) can be assembled to the above flow guide unit (100). In FIG. 6, reference numeral B2 represents a fastener for fixing the flow switching part (240), which will be described later and surrounds the temperature controller (140), to the above flow guide unit (100); B3 represents a fastener for fixing the above flow controller (150) to the above flow guide unit (100); and B4 represents a fastener for fixing the above flow controller (150) to the above flow guide unit (100).

[0134] The temperature controller (140), the flow rate controller (150), the filter (160), the generator (170), and the water outlet selector (190) can each be connected to the flow guide unit (100). Here, connection means that water can pass between the two parts. In this embodiment, except for the generator (170) and the water outlet selector (190), the respective parts are not directly connected to each other but can be indirectly connected through the flow guide unit (100). Accordingly, the flow guide unit (100) can handle the flow path for water flow, and the flow guide unit (100) can provide a sufficiently wide and uniformly sized flow path inside.

[0135] The temperature controller (140) and the flow controller (150) may be spaced apart from each other in the left-right direction. Between the temperature controller (140) and the flow controller (150), the filter (160), the generator (170), the transfer pipe (180), and the water outlet selector (190) may be arranged. In this way, if the parts other than the flow guide unit (100) are not arranged in the front-to-back direction but are arranged in the left-to-right or up-to-down direction, the front-to-back length of the water supply device (10) can be minimized. As previously explained, if the front-to-back length of the water supply device (10) is short, the bending moment applied to the installation adapter (7) can be reduced.

[0136] Referring to FIG. 7, a plurality of connectors (122b, 127a, OH2, FH) are opened in front of the Euro guide unit (100). The plurality of connectors (122b, 127a, OH2, FH) are connected to the flow paths inside the Euro guide unit (100). Additionally, the plurality of connectors (122b, 127a, OH2, FH) are connected to the temperature controller (140), the flow rate controller (150), the filter (160), the generator (170), and the water outlet selector (190). Accordingly, the temperature controller (140), the flow rate controller (150), the filter (160), the generator (170), and the water outlet selector (190) are connected to each other via the Euro guide unit (100) and can exchange water. For reference, only parts of the above-mentioned connectors (122b, 127a, OH2, FH) are shown in Fig. 7. All of the above-mentioned connectors are shown in Fig. 12, which will be explained again below.

[0137] Referring to FIG. 8, the sequence of water flow between the above components is as follows: First, raw water introduced into the inlet sections (IH1, IH2, shown in FIG. 5) of the flow guide unit (100) is supplied to the temperature controller (140). After the cold water and hot water are mixed in the temperature controller (140), the mixed water is delivered to the flow rate controller (150) by the flow guide unit (100). The mixed water is delivered back to the flow guide unit (100) at a flow rate controlled by the flow rate controller (150), and the flow guide unit (100) delivers the mixed water to the filter (160). The purified water purified in the filter (160) is delivered to the generator (170) via the flow guide unit (100). As the purified water passes through the generator (170), it generates power for the generator (170) and is delivered to the water outlet selector (190) via the transfer pipe (180) described below. The purified water is discharged to one of the outlet sections (OH1, OH2) along the path selected at the water outlet selector (190). More details regarding this water flow will be described below.

[0138] In FIGS. 9 and FIGS. 10, the components placed in the installation space (21) are respectively shown in a top view and a bottom view. As seen therein, the installation space (21) can be divided into a first area (T1) and a second area (T2). The first area (T1) and the second area (T2) are arranged in the front-rear direction. The first area (T1) and the second area (T2) are arbitrarily partitioned sections of the installation space (21). The first area (T1) and the second area (T2) may not actually be clearly distinguishable.

[0139] The above-mentioned Euro guide unit (100) may be placed in the first area (T1). The temperature controller (140), the flow controller (150), the filter (160), the generator (170), the transfer pipe (180), and the water outlet selector (190) may be placed in the second area (T2) of the installation space (21). Here, the second area (T2) is positioned closer to the front of the casing (20) than the first area (T1). Conversely, the first area (T1) is positioned closer to the installation surface (W) than the second area (T2). In this embodiment, the Euro guide unit (100) is placed in the first area (T1) and does not encroach upon the second area (T2). This allows the installation space (21) to be utilized efficiently.

[0140] FIGS. 11 to 13 illustrate two parts constituting the Euro guide unit (100) in a disassembled state. The Euro guide unit (100) has a framework formed by a Euro body (110, 120). The Euro body (110, 120) may include a first Euro body (110) and a second Euro body (120). The first Euro body (110) and the second Euro body (120) may have corresponding shapes. When the first Euro body (110) and the second Euro body (120) are combined, they may have the same area so that neither one protrudes further outward from the perimeter. When the first Euro body (110) and the second Euro body (120) are combined, a plurality of Euros may be formed between them.

[0141] The plurality of fluid paths can connect the inlet sections (IH1, IH2) and the outlet sections (OH1, OH2). The plurality of fluid paths can connect components such as a temperature controller (140), a flow controller (150), a filter (160), and a generator (170) to allow water to flow between them.

[0142] Referring to FIG. 11, the first flow path (WP1) may be provided in the first flow path body (110) in a first recess (111) that is recessed relatively backward from the surface of the first flow path body (110). In FIG. 12, the second flow path (WP2) may be provided in the second flow path body (120) in a second recess (121) that is recessed relatively forward from the surface of the second flow path body (120). The first flow path (WP1) and the second flow path (WP2) may have corresponding shapes and positions. The first flow path (WP1) and the second flow path (WP2) may form continuous flow paths in the front-rear direction.

[0143] Here, the first flow paths (WP1) include all of the plurality of paths formed in the first flow path body (110). The plurality of paths formed in the first flow path body (110) are independent paths and form paths for water flow. Similarly, the second flow paths (WP2) include all of the plurality of paths formed in the second flow path body (120). The plurality of paths formed in the second flow path body (120) are independent paths and form paths for water flow.

[0144] In this embodiment, the first recessed portion (111) in which the first flow path portions (WP1) are formed is shaped to be relatively recessed compared to the first sealing portion (111') protruding from the first flow path body (110). The second recessed portion (121) in which the second flow path portions (WP2) are formed is shaped to be relatively recessed compared to the second sealing portion (121') protruding from the second flow path body (120).

[0145] The first contact portion (111') may protrude from the surface of the first flow body (110) toward the second flow body (120). Conversely, the second contact portion (121') may protrude from the surface of the second flow body (120) toward the first flow body (110). The first contact portion (111') and the second contact portion (121') may be in close contact with each other to form the flow channels. When the first contact portion (111') and the second contact portion (121') are in close contact, the first contact portion (111') and the second contact portion (121') become a kind of wall that is continuous in the front-rear direction, and the flow channels may be formed between the walls.

[0146] In the portion where the first Euro body (110) and the second Euro body (120) face each other, the Euro channels can be formed in the remaining portion excluding the portion where the first contact portion (111') and the second contact portion (121') are in contact. That is, since the first contact portion (111') and the second contact portion (121') are a kind of wall that is continuous in the front-rear direction, the Euro channels, which are empty spaces, can be formed in the remaining portion excluding the portion where the first contact portion (111') and the second contact portion (121') are in contact.

[0147] The first contact portion (111') and the second contact portion (121') can be fused together. Here, fusion means being fixed in a state of being in close contact with each other. The first contact portion (111') and the second contact portion (121') can be fused together by vibration fusion, thermal fusion, or ultrasonic fusion. Thermal fusion can be implemented by applying pressure to the first Euro body (110) and the second Euro body (120), which are fixed to two jigs, with a heating plate heated to a temperature slightly higher than the melting temperature of the material to heat, soften, and melt them, and then removing the heating plate when the fusion portion is sufficiently melted, applying pressure to each other, and cooling until they harden to fuse them.

[0148] As another example, the first contact portion (111') and the second contact portion (121') may be joined by a bonding method. As yet another example, the first Euro body (110) and the second Euro body (120) may be joined to each other using a separate fastener such as a screw. In this case, the first contact portion (111') and the second contact portion (121') may be sealed using a rubber sealing member. Reference numerals BH1 and BH2 represent body fastening holes formed in the first Euro body (110) and the second Euro body (120), respectively, which can be used for joining between the first Euro body (110) and the second Euro body (120) or for joining between the Euro guide unit (100) and other parts.

[0149] Referring to the enlarged portion of FIG. 14, the first contact portion (111') and the second contact portion (121') may have corresponding uneven structures. In this embodiment, a relatively recessed coupling groove (111a) is formed in the first contact portion (111'), and a coupling protrusion (121a) that is inserted into the coupling groove (111a) is provided in the second contact portion (121'). When the coupling groove (111a) and the coupling protrusion (121a) are coupled in this way, the coupling area increases, allowing for a stronger coupling between the first contact portion (111') and the second contact portion (121'). As another example, conversely, a relatively protruding coupling protrusion may be provided in the first contact portion (111'). As another example, the coupling groove (111a) and the coupling protrusion (121a) may be omitted, and the first contact portion (111') and the second contact portion (121') may have a planar structure.

[0150] As shown in FIG. 14, the first flow body (110) includes a first flow surface (110a) that is recessed backward to form a flow path, and a second flow surface (110b) formed on the opposite side of the first flow surface (110a). The second flow surface (110b) has a structure that protrudes toward the rear cover (50). More precisely, the second flow surface (110b) protrudes backward to the same extent as the first flow surface (110a) is recessed backward. In this way, the thickness (D) of the first flow body (110) can be formed uniformly in the portion forming the flow path. A flow structure that protrudes backward while having the same thickness acts as a kind of reinforcing rib, thereby increasing the durability of the first flow body (110). In addition, this structure of the first flow body (110) can reduce the weight of the flow guide unit (100). If the second Euro surface (110b) has a flat structure without protruding backward, the first Euro body (110) cannot form a rib structure around the Euro, and the weight of the Euro guide unit (100) also increases.

[0151] The above-mentioned flow paths can form a path independent of the installation space (21). Since the above-mentioned flow paths are provided inside the flow path guide unit (100), the flow paths can be partitioned from the installation space (21) to form an independent path. That is, water inside the faucet (10) flows only within the parts such as the flow path guide unit (100) or the temperature controller (140), and the installation space (21) itself does not guide the flow of water.

[0152] In this embodiment, the plurality of channels may be arranged on the same plane within the channel guide unit (100). Here, the same plane refers to a virtual plane, which is a plane extending in a direction orthogonal to the front-rear direction. As shown in FIG. 14, a virtual extension line (SP) constituting the same plane is indicated. When the plurality of channels are arranged on the same plane within the channel guide unit (100), the width in the front-rear direction occupied by the channels is maintained constant, so the channel guide unit (100) can be miniaturized. In addition, when the channels are arranged on the same plane, excessive bends in the channels are eliminated, allowing for smooth water flow.

[0153] Referring to FIG. 13, the plurality of flow paths may be composed of independent individual flow paths (P1 / P1', P2 / P2', P3 / P3', P4 / P4'). The individual flow paths (P1 / P1', P2 / P2', P3 / P3', P4 / P4') can (i) deliver water introduced through inlet sections (IH1, IH2) to each component, (ii) connect the components, and (iii) discharge water that has passed through the components through outlet sections (OH1, OH2). The individual flow paths (P1 / P1', P2 / P2', P3 / P3', P4 / P4') may have independent paths. Here, independence may mean that each individual flow path (P1 / P1', P2 / P2', P3 / P3', P4 / P4') has a partitioned path and is not directly connected to one another. The individual flow paths (P1 / P1', P2 / P2', P3 / P3', P4 / P4') that are disconnected from one another in this way are indirectly connected by components such as the temperature controller (140).

[0154] Referring to FIGS. 13 and 15, the first flow body (110) constituting the flow guide unit (100) may be provided with inlet sections (IH1, IH2). The inlet sections (IH1, IH2) are parts for receiving raw water from the outside into the flow paths. Cold water and hot water may be supplied through the inlet sections (IH1, IH2). In this embodiment, the inlet sections (IH1, IH2) include a first inlet section (IH1) for cold water inflow and a second inlet section (IH2) for hot water inflow. As another example, only one inlet section may be provided in the first flow body (110).

[0155] The inlet sections (IH1, IH2) may be opened in the front-rear direction of the first flow body (110). More precisely, the first flow body (110) and the second flow body (120) are connected to each other in a first direction (front-rear direction), and the inlet sections (IH1, IH2) may also be opened in the first direction. In this way, the inlet sections (IH1, IH2) may be provided penetrating a wide portion of the first flow body (110), and the diameter of the inlet sections (IH1, IH2) may be increased. When the diameter of the inlet sections (IH1, IH2) is increased, external raw water can flow in smoothly through the inlet sections (IH1, IH2). If the diameter of the inlet sections (IH1, IH2) is small, the water pressure in the inlet sections (IH1, IH2) increases, and there is a risk that cracks and leakage may occur in the fused portion between the first flow body (110) and the second flow body (120). In this embodiment, the water pressure can be reduced by opening the inlet sections (IH1, IH2) in the first direction.

[0156] A first outlet through-hole (OH2A) that passes through a second outlet section (OH2) may be formed in the first Euro body (110). Through the first outlet through-hole (OH2A), an outlet nozzle (200, shown in FIG. 10), which will be described later, may protrude outward. In this embodiment, the second outlet section (OH2) is formed in the outlet nozzle (200).

[0157] For reference, the second outlet section (OH2) may be a part through which water passing through the Euro guide unit (100) is discharged to the outside. Here, "outside" refers to the space through which water is discharged via the outlet section. A separate second discharge pipe (3, see FIG. 1) may be connected to the second outlet section (OH2) to allow water to be discharged from a distant location. In this embodiment, the first outlet section (OH1) is provided in the water discharge selector (190). As another example, at least one of the first outlet section (OH1) or the second outlet section (OH2) may be provided directly in the first Euro body (110). As yet another example, the second outlet section (OH2) may also be provided in the water discharge selector (190).

[0158] In this embodiment, the first outlet section (OH1) and the second outlet section (OH2) are formed in the front-rear direction of the flow guide unit (100). The first outlet section (OH1) and the second outlet section (OH2) may extend in the front-rear direction, which is the same as the thickness direction of the flow guide unit (100). At this time, the direction in which water is finally discharged through the first outlet section (OH1) and the second outlet section (OH2) may be in the up-down direction or the left-right direction, rather than the front-rear direction.

[0159] Service holes (SH1, SH2) may be opened in the first Euro body (110). The service holes (SH1, SH2) are for maintenance of the water tap (10). The service holes (SH1, SH2) may normally be kept closed by separate plugs (HP1, HP2, shown in FIG. 18). By removing the plugs (HP1, HP2) and injecting cleaning water or high-temperature steam into the interior of the Euro guide unit (100) through the service holes (SH1, SH2), the fluid paths and each component inside the Euro guide unit (100) can be cleaned.

[0160] As shown in FIG. 13, in the first flow body (110) and the second flow body (120), flow paths are formed in pairs at corresponding positions. A pair of flow paths formed to correspond to each other in the first flow body (110) and the second flow body (120) are combined to form a single flow path. In this embodiment, the flow paths of the first flow body (110) and the flow paths of the second flow body (120) are assigned corresponding reference numerals. For example, the inflow flow path (P1) formed in the first flow body (110) is indicated by reference numeral P1, and the inflow flow path (P1) formed in the second flow body (120) is indicated by reference numeral P1'. Below, the explanation is based on the flow paths formed in the first flow body (110), and the specific explanation of the flow paths of the second flow body (120) is replaced by the explanation of the flow paths of the first flow body (110).

[0161] FIG. 15 illustrates the first Euro body (110). FIG. 15 shows the direction of water flow along the flow path of the first Euro body (110) as indicated by an arrow. For reference, FIG. 15 illustrates the discharge of mixed water in which cold water and hot water are mixed. Looking at the flow paths of the first Euro body (110), an inlet flow path (P1) is formed in the first Euro body (110). The inlet flow path (P1) is a flow path into which raw water is introduced. The inlet flow path (P1) can be divided into a first inlet flow path (P1a) and a second inlet flow path (P1b). The first inlet flow path (P1a) is a path into which cold water from the raw water is introduced, and the second inlet flow path (P1b) is a path into which hot water is introduced.

[0162] At this time, the first inlet section (IH1) is connected to one end of the first inlet passage (P1a). The other end of the first inlet passage (P1a) is connected to the first temperature control connector (122a, shown in FIG. 13), which will be described later. The first temperature control connector (122a) is formed at the other end of the first inlet passage (P1a') of the second passage body (120). For reference, FIG. 15 only shows the first passage body (110), so the first temperature control connector (122a) formed in the second passage body (120) is not visible, but the location of the first temperature control connector (122a) is indicated by a dotted line to aid understanding.

[0163] The first temperature control connector (122a) is connected to the temperature controller (140). More precisely, the first temperature control connector (122a) is connected to the flow path switching section (240) described below, and the flow path switching section (240) delivers the cold water that has entered the first temperature control connector (122a) to the temperature controller (140). Accordingly, the cold water that has entered the first inlet section (IH1) passes through the first inlet flow path (P1a) and is then delivered to the temperature controller (140) through the first temperature control connector (122a). Arrow ① in FIG. 15 indicates the direction in which the cold water flows along the first inlet flow path (P1a).

[0164] The second inlet section (IH2) is connected to one end of the second inlet passage (P1b). The second temperature control connector (122b, shown in FIG. 13), which will be described later, is connected to the other end of the second inlet passage (P1b). The second temperature control connector (122b) is formed at the other end of the second inlet passage (P1b') of the second passage body (120). For reference, FIG. 15 only shows the first passage body (110), so the second temperature control connector (122b) formed in the second passage body (120) is not visible, but the location of the second temperature control connector (122b) is indicated by a dotted line to aid understanding.

[0165] The second temperature control connector (122b) is connected to the temperature controller (140). More precisely, the second temperature control connector (122b) is connected to the flow path switching section (240) described below, and the flow path switching section (240) delivers the hot water that has entered the second temperature control connector (122b) to the temperature controller (140). Thus, the hot water that has entered the second inlet section (IH2) passes through the second inlet flow path (P1b) and is then delivered to the temperature controller (140) through the second temperature control connector (122b). Arrow ② in FIG. 15 indicates the direction in which the hot water flows along the second inlet flow path (P1b).

[0166] A mixing channel (P2) is formed in the first flow body (110). The mixing channel (P2) is a path through which mixed water, in which cold water and hot water are mixed, passes through the temperature controller (140). One end of the mixing channel (P2) is connected to a third temperature control connector (122c). In FIG. 15, the location of the third temperature control connector (122c) is indicated by a dotted line. As shown in FIG. 13, the third temperature control connector (122c) is formed in the second flow body (120). The third temperature control connector (122c) is connected to the mixed water discharge pipe (141a, shown in FIG. 19) of the temperature controller (140), which will be described later, and receives the mixed water discharged by the temperature controller (140). For reference, arrow ③ in FIG. 15 indicates the direction in which the mixed water flows along the mixing channel (P2).

[0167] The other end of the above mixing channel (P2) can be connected to the first flow control connector (123a) of the above flow control connector (123). In FIG. 15, the location of the first flow control connector (123a) is indicated by a dotted line. As shown in FIG. 13, the first flow control connector (123a) is configured to be branched, and a second flow control connector (123b) can be formed between them. The mixed water flowing into the first flow control connector (123a) can have its flow controlled by the flow regulator (150) to become controlled water, and then the controlled water can be discharged through the second flow control connector (123b).

[0168] The regulated water discharged through the second flow control connector (123b) flows along the filter channel (P3) formed in the first flow body (110). The filter channel (P3) delivers the regulated water with the controlled flow rate to the filter (160). In FIG. 15, arrow ④ represents the path of the regulated water flowing along the filter channel (P3).

[0169] Both ends of the filter channel (P3) are connected to the second flow control connector (123b) and the filter connector (FH), respectively. More precisely, the other end of the filter channel (P3) is connected to the first filter connector (124a) that constitutes the filter connector (FH). The first filter connector (124a) serves to transfer the controlled water to the filter (160). Referring to FIG. 13, the first filter connector (124a) and the second filter connector (124b) that constitute the filter channel (P3) are formed side by side on the second channel body (120). The second filter connector (124b) serves as an outlet through which purified water that has passed through the filter (160) is discharged. For reference, the first filter connector (124a) and the second filter connector (124b) can be connected to the filter inlet (39a, illustrated in FIG. 5) and the filter outlet (39b, illustrated in FIG. 5), respectively, of the filter shell (39) described above.

[0170] Referring to FIG. 6, the regulated water can be introduced into / out of the inlet / outlet (164) of the filter (160) through the filter channel (P3). The regulated water can be supplied to the filter inlet (164a) of the filter (160). The regulated water that has passed through the filter (160) can become purified water. The purified water can be discharged through the filter outlet (164b) of the filter (160).

[0171] The purified water discharged through the second filter connector (124b) is transferred to the transfer path (P4). The transfer path (P4) is a path connecting the filter (160) and the generator (170). Both ends of the transfer path (P4) are connected to the second filter connector (124b) and the generator connector (127a), which will be described below, respectively. In FIG. 15, the location of the generator connector (127a) is indicated by a dotted line. As shown in FIG. 13, the generator connector (127a) can be formed in the generator connection part (125, see FIG. 6) provided in the second path body (120). Arrow ⑤ in FIG. 15 represents the path of the purified water flowing along the transfer path (P4).

[0172] After flowing through the above-mentioned transmission path (P4), the water is transmitted to the generator (170) through the generator connector (127a). As the water passes through the generator (170), it can generate power in the generator (170). The generator (170) is positioned in front of the above-mentioned path guide unit (100), and in FIG. 15, the path flowing inside the generator (170) is represented by a dotted line and arrow ⑥. For reference, in FIG. 7, the generator (170) is provided with a generator inlet (172) connected to the generator connector (127a) of the above-mentioned path guide unit (100), and the generator (170) may include a bracket (171).

[0173] The purified water passing through the generator (170) is transferred to the transfer pipe (180). Referring to FIGS. 7 and 8, the transfer pipe (180) is positioned in front of the flow guide unit (100) and transfers the purified water to the water outlet selector (190). To this end, one end (181) of the transfer pipe (180) is connected to the generator (170), and the other end (185) is connected to the water outlet selector (190). Reference numeral 182 indicates a transfer section that transfers the purified water in the height direction, that is, in the up-and-down direction. The transfer pipe (180) may be omitted or may be integrally provided with the generator (170) or the water outlet selector (190). The transfer pipe (180) may be supported on the flow guide unit (100) by a pipe mounting section (186).

[0174] As another example, the above-mentioned transfer pipe (180) may be composed of a flow sensor connected to the generator (170). The flow sensor may be composed of a device that connects the generator (170) and the water outlet selector (190) and simultaneously measures the flow rate of purified water passing through the generator (170).

[0175] Looking again at FIG. 15, the path through which the purified water flows in the transfer pipe (180) is represented by a dotted line and arrow ⑦. The purified water passing through the transfer pipe (180) is transferred to the water outlet selector (190, not shown in FIG. 15). Through the water outlet selector (190), the purified water is discharged to the first outlet section (OH1) or the second outlet section (OH2). FIG. 15 shows a first outlet through-hole (OH2A) connected to the second outlet section (OH2), and the first outlet through-hole (OH2A) penetrates the first flow body (110) in the front-rear direction.

[0176] As shown in FIG. 15, in this embodiment, the first inlet channel (P1a), the second inlet channel (P1b), and the mixing channel (P2) are arranged in the vertical direction at different heights from each other. The first inlet channel (P1a) is placed at the relatively highest position, and the mixing channel (P2) is placed at the relatively highest position. The second inlet channel (P1b) is placed between the first inlet channel (P1a) and the mixing channel (P2).

[0177] FIG. 16 illustrates the process in which external cold water is introduced and discharged as cold water without being mixed with hot water. As shown here, the cold water introduced into the first inlet section (IH1) can move along the first inlet path (P1a) (direction of arrow ①). The cold water introduced into the temperature controller (140) through the first temperature control connector (122a) can be introduced into the interior of the temperature controller (140). The temperature controller (140) can discharge the introduced cold water without mixing it with hot water.

[0178] Cold water discharged through the third temperature control connector (122c) of the temperature controller (140) can flow along the mixing path (P2) (direction of arrow ②). Cold water reaching the first flow rate control connector (123a) can be introduced into the flow rate controller (150). Cold water introduced into the interior of the flow rate controller (150) through the first flow rate control connector (123a) of the flow rate controller (150) can be discharged through the second flow rate control connector (123b) of the flow rate controller (150) after becoming controlled water with a controlled discharge flow rate.

[0179] The regulated water discharged through the second flow control connector (123b) can be supplied to the filter (160) through the filter path (P3) (direction of arrow ③). The regulated water that has passed through the filter (160) can become purified water. After passing through the filter (160), the purified water is transferred back into the flow guide unit (100) through the second filter connector (124b). Subsequently, the purified water can be transferred toward the generator (170) through the transfer path (P4) (direction of arrow ④). In FIG. 16, arrow ⑤ indicates the path through which the purified water passes through the generator (170), and arrow ⑥ indicates the path through which the purified water passes through the transfer pipe (180). Since these paths have been described previously, a detailed explanation will be omitted.

[0180] Meanwhile, FIG. 17 illustrates the process in which external hot water is introduced and discharged in a hot water state without being mixed with cold water. As shown here, the hot water introduced into the second inlet section (IH2) can move along the second inlet path (P1b) (direction of arrow ①). The hot water introduced into the temperature controller (140) through the second temperature control connector (122b) can be introduced into the interior of the temperature controller (140). The temperature controller (140) can discharge the introduced hot water without mixing it with cold water.

[0181] The hot water discharged through the third temperature control connector (122c) of the temperature controller (140) can flow along the mixing path (P2) (direction of arrow ②). The hot water reaching the first flow rate control connector (123a) can be introduced into the flow rate controller (150). The hot water introduced into the interior of the flow rate controller (150) through the first flow rate control connector (123a) of the flow rate controller (150) can be discharged through the second flow rate control connector (123b) of the flow rate controller (150) after becoming controlled water with a controlled discharge flow rate.

[0182] The regulated water discharged through the second flow control connector (123b) can be supplied to the filter (160) through the filter path (P3) (direction of arrow ③). The regulated water passing through the filter (160) can become purified water. After passing through the filter (160), the purified water is transferred back into the flow guide unit (100) through the second filter connector (124b). Subsequently, the purified water can be transferred toward the generator (170) through the transfer path (P4) (direction of arrow ④). In FIG. 17, arrow ⑤ indicates the path through which the purified water passes the generator (170), and arrow ⑥ indicates the path through which the purified water passes the transfer pipe (180). Since these paths have been described previously, a detailed explanation will be omitted.

[0183] Meanwhile, looking at the second Eurobody (120) above, as shown in FIG. 13, the second Eurobody (120) is provided with a first mounting part (122) in which the temperature controller (140) is placed. The first mounting part (122) protrudes forward from the front of the second Eurobody (120). Inside the first mounting part (122), the Euro switching part (240) is placed together with the temperature controller (140). The first mounting part (122) is connected to a temperature control connector (TH). The first temperature control connector (122a), the second temperature control connector (122b), and the third temperature control connector (122c) constituting the temperature control connector (TH) can each be connected to the first mounting part (122).

[0184] Referring to FIG. 11, the first mounting portion (122) may have a roughly cylindrical shape. A first mounting space (122') is formed inside the first mounting portion (122). The first mounting space (122') is open at the front, through which the temperature controller (140) and the flow path switching portion (240) can be mounted. A switching portion fastening hole (122'') for assembly with the flow path switching portion (240) may be formed at the edge of the first mounting space (122').

[0185] The second Eurobody (120) is provided with a second mounting part (123) in which the flow regulator (150) is disposed. The second mounting part (123) protrudes forward from the front of the second Eurobody (120). The flow regulator (150) is housed inside the second mounting part (123). The second mounting part (123) is connected to a flow control connector (CH). A first flow control connector (123a) and a second flow control connector (123b) constituting the flow control connector (CH) can each be connected to the second mounting part (123).

[0186] The second mounting portion (123) may have a roughly cylindrical shape. A second mounting space (123') is formed inside the second mounting portion (123). The second mounting space (123') is open at the front so that the flow regulator (150) can be mounted therethrough. A regulator fastening hole (123'', shown in FIG. 11) for assembly with the flow regulator (150) may be formed at the edge of the second mounting space (123').

[0187] In the second Eurobody (120) above, a filter connection part (124), a generator connection part (127), and a second outlet through hole (OH2B) may be arranged between the first mounting part (122) and the second mounting part (123). A filter connection part (FH) composed of the first filter connection part (124a) and the second filter connection part (124b) may be formed in the filter connection part (124). The generator connection part (127a) may be formed in the generator connection part (127). In this embodiment, the filter connection part (124) and the generator connection part (127) protrude forward so that connection with the filter (160) and the generator (170) can be easily made.

[0188] The second Eurobody (120) is provided with a second outlet section connection part (129). The second outlet section connection part is penetrated in the front-rear direction, and a second outlet through hole (OH2B) is formed at its center. The second outlet through hole (OH2B) corresponds to the first outlet through hole (OH2A) and is connected to the second outlet section (OH2). The second outlet section connection part (129) is connected to the outlet nozzle (200) and serves to discharge water delivered from the water discharge selector (190) to the second outlet section (OH2) provided in the outlet nozzle (200).

[0189] The second outlet connecting portion (129) may have a ring shape protruding forward. A support ledge (129a) may be provided on the edge of the second outlet connecting portion (129) that protrudes in this manner. The support ledge (129a) is for fixing the outlet nozzle (200), and the outlet nozzle (200) may be caught on the support ledge (129a) to maintain a specific installation angle. The outlet nozzle (200) may be provided with a nozzle protrusion (not shown) that engages with the support ledge (129a). Such a support ledge (129a) may be provided on the edge of the second outlet connecting portion (129). The support ledge (129a) may protrude further forward from the second outlet connecting portion (129). Multiple support ledges (129a) may be arranged along the rotational direction of the outlet nozzle (200). As another example, the support jaw (129a) can be omitted.

[0190] The second Eurobody (120) may be provided with a reinforcing rib (128). The reinforcing rib (128) may protrude forward or backward from the surface of the second Eurobody (120). FIG. 11 illustrates the reinforcing rib (128) protruding forward from the front of the second Eurobody (120). The reinforcing rib (128) may be extended along the direction of travel of the Euro.

[0191] Referring to FIG. 14, the second Eurobody (120) may be provided with support bosses (128'). The support bosses (128') protrude forward from the surface of the second Eurobody (120). The second support bosses (128') may support components positioned in front of the Euro guide unit (100), such as the generator (170) and the transmission pipe (180). To this end, the support bosses (128') protrude to a position adjacent to the surface of the components.

[0192] Referring to FIG. 18, the flow of raw water entering the faucet (10) and the flow of regulated water discharged to the outside after passing through the faucet (10) are illustrated. Arrow ① indicates the flow of cold water among the raw water. For reference, only a part of the first inlet path (P1a) guiding the cold water is illustrated in FIG. 18, so the flow of cold water is represented by a dotted line. Arrow ② indicates the flow of hot water among the raw water, and the hot water can be guided along the second inlet path (P1b). In this way, the flow of raw water can be formed in the left and right directions along the path guide unit (100).

[0193] Looking at the flow of the regulated water discharged after passing through the generator (170), the flow discharged to the first outlet section (OH1) by the water outlet selector (190) is indicated by arrow ③ in FIG. 18. The first outlet section (OH1) is formed below the water tap (10). The flow discharged to the second outlet section (OH2) by the water outlet selector (190) is indicated by arrow ④ in FIG. 18. The second outlet section (OH2) is formed by the outlet nozzle (200), and in this embodiment, the second outlet section (OH2) is formed behind the first outlet section (OH1). More precisely, the second outlet section (OH2) is provided at a position away from the rear of the flow guide unit (100). In FIG. 18, reference numeral 197 represents a water discharge operation unit for operating the water discharge selector (190), and a separate operation button may be combined therein.

[0194] Referring to FIG. 19, we will examine the temperature controller (140). The temperature controller (140) can control the temperature by mixing the incoming cold water and hot water. In this case, the temperature controller (140) can be viewed as a type of valve. In this embodiment, the temperature controller (140) can implement a constant temperature function that maintains the temperature of the mixed water near a set temperature. The temperature controller (140) can control the ratio of the mixed cold water and hot water by adjusting the opening degree of the valve that opens and closes internally.

[0195] The user can control the temperature controller (140) by operating the control knob (300). When the control knob (300) is rotated, a control rotor (not shown) provided inside the temperature control body (141) constituting the temperature controller (140) is rotated. At this time, a side permeable section (142) is provided on the side of the temperature control body (141), and the side permeable section (142) allows cold water and hot water to pass through. The cold water / hot water passing through the side permeable section (142) is delivered to a mixed water discharge pipe (141a) formed in the center of the temperature controller (140). At this time, the amount of cold water and hot water delivered to the mixed water discharge pipe (141a) changes depending on the rotation angle of the control rotor.

[0196] More specifically, the side permeable section (142) may include a first side permeable section (142a) and a second side permeable section (142b). The first side permeable section (142a) and the second side permeable section (142b) are formed spaced apart from each other with respect to the front-rear direction. Looking at FIG. 19, the first side permeable section (142a) is located further forward than the second side permeable section (142b). Different raw water passes through the first side permeable section (142a) and the second side permeable section (142b). For example, cold water passes through the first side permeable section (142a), and hot water passes through the second side permeable section (142b). Then, the cold water and hot water are mixed inside the mixed water discharge pipe (141a).

[0197] At this time, when the control rotor of the temperature control body (141) is rotated, the area of ​​the first side permeable section (142a) and the second side permeable section (142b) that are opened to the outside, that is, to the flow path switching section (240) to be described later, may change. Accordingly, the area of ​​the first side permeable section (142a) and the second side permeable section (142b) that are connected to the flow path guide unit (100) also changes, and the amount of cold water and hot water delivered to the mixed water discharge pipe (141a) is controlled. For example, when the control knob (300) is rotated clockwise (based on FIG. 3) and the control rotor is rotated, the area of ​​the first side permeable section (142a) that is opened widens, and the flow rate of cold water flowing into the mixed water discharge pipe (141a) increases. The structure of such a temperature controller (140) is one example, and the temperature controller (140) may have various structures for mixing raw water of different temperatures through rotational movement.

[0198] The above temperature controller (140) may be provided with a controller head (146). The controller head (146) protrudes forward from the temperature control body (141). The controller head (146) may be surrounded by the temperature control mounting part (37) inside the casing (20). The controller head (146) may have a roughly cylindrical shape. The controller head (146) protrudes further forward from the flow path switching part (240) to be described later.

[0199] The above regulator head (146) is provided with a head coupling part (147), and the head coupling part (147) can be coupled to a knob holder (360) to be described later. When the control knob (300) rotates the knob holder (360), the head coupling part (147) transmits the rotational force of the control knob (300) to a control rotor (not shown) of the temperature control body (141), causing the control rotor to rotate. The head coupling part (147) can be positioned on the rotation axis of the control knob (300). In this embodiment, the head coupling part (147) and the knob holder (360) can be assembled with a knob fastener (B6).

[0200] Reference numeral 149 indicates a controller fastener, and the controller fastener (149) can fix the temperature control body (141) to the flow path switching part (240) by screwing it to the flow path switching part (240) to be described later. As another example, the temperature control body (141) may be directly fastened to the flow path switching part (240), or the temperature controller (140) itself may be directly coupled to the flow path guide unit (100).

[0201] Drawing symbol TS represents a temperature sensor, and the temperature sensor (TS) can measure the temperature of the mixed water passing through the temperature controller (140). In this embodiment, the temperature controller (140) may be configured as an automatic thermostat that includes a temperature sensor (TS) and allows water to be supplied at a temperature set by the user by rotating the control knob (300).

[0202] The above temperature controller (140) may be surrounded by a flow path switching section (240). The flow path switching section (240) connects the temperature controller (140) and the flow path guide unit (100). The flow path switching section (240) guides the cold water to the first side permeable section (142a) and guides the hot water to the second side permeable section (142b). In FIG. 19, reference numeral B2 indicates a fastener for assembling the flow path switching section (240) to the second flow path body (120).

[0203] As shown in FIG. 19, the Euro switching section (240) is provided with a first Euro connecting section (243) protruding rearward toward the Euro guide unit (100), and the first Euro connecting section (243) is connected to the first inflow section (P1a). At the same time, the first Euro connecting section (243) is connected to the first side permeable section (142a). In this embodiment, the first Euro connecting section (243) is provided in the switching section body (241) of the Euro switching section (240).

[0204] At this time, a first connecting passage (243a) is formed in the first flow path connecting part (243) that is connected to the first inflow path (P1a) and the first temperature control connector (122a). A transfer passage (243b) is opened in the first connecting passage (243a), and the transfer passage (243b) can transfer raw water (cold water) that has passed through the first connecting passage (243a) to the first side permeable part (142a). Accordingly, the cold water passes through a path consisting of the first inflow path (P1a) - the first temperature control connector (122a) - the first connecting passage (243a) - the transfer passage (243b) - the first side permeable part (142a) - the mixed water discharge pipe (141a). This path is represented by arrow ① in FIG. 19.

[0205] The above-mentioned Euro switching section (240) is provided with a second Euro connecting section (245) connected to the above-mentioned Euro guide unit (100). The second Euro connecting section (245) is a kind of empty space and is connected to the second inflow section (P1b). At the same time, the second Euro connecting section (245) is connected to the second side permeable section (142b). Accordingly, hot water passes through a path consisting of the second inflow section (P1b) - the second temperature control connector (122b) - the second Euro connecting section (245) - the second side permeable section (142b) - the mixed water discharge pipe (141a). This path is represented by arrow ② in FIG. 19.

[0206] The above Euro switching unit (240) can reverse the inflow paths of the cold water and hot water depending on the coupling direction in which it is coupled to the first mounting unit (122). For example, a supply device (pipe, etc.) embedded in the installation surface (W) supplies cold water and hot water, and generally, the cold water can be positioned relatively to the left among the cold water and hot water. However, depending on the installation environment, there may also be cases where the cold water is positioned relatively to the right. In this case, when the user rotates the control knob (300) clockwise, hotter water is supplied. Therefore, there is a problem that the temperature display label of the control knob (300) must be changed for the user's convenience and safety.

[0207] In this embodiment, in such cases, the coupling direction in which the above-mentioned Euro switching unit (240) is coupled to the Euro guide unit (100) can be changed so that a higher temperature water is supplied when the control knob (300) is rotated counterclockwise. That is, even if the installation environment in which the faucet (10) is installed is different, the user can be provided with the operating direction of the control knob (300) that is generally familiar to the user.

[0208] Referring to the structure in FIG. 20, FIG. 20 illustrates the Euro switching section (240) arranged in a symmetrical form compared to FIG. 19. Here, a symmetrical form means that the Euro switching section (240) is in a rotated state. After the Euro switching section (240) is separated from the first mounting section (122) in the state of FIG. 19, if it is mounted back onto the first mounting section (122) in a state rotated 180 degrees, it can be in the state shown in FIG. 20. In this case, the first Euro connecting section (243) is connected to the second inflow section (P1b), and the second Euro connecting section (245) is connected to the first inflow section (P1a). That is, the Euro switching section (240) is connected to the Euro guide unit (100) in the opposite way to FIG. 19. Reference numeral 241 indicates the body of the switching section.

[0209] Looking more specifically, the first flow path connection part (243) in a protruding shape connects the second inlet flow path (P1b) and the mixed water discharge pipe (141a). The second flow path connection part (245) in a relatively recessed shape connects the first inlet flow path (P1a) and the second side control part (142b). In this way, the inlet paths of cold water and hot water can be reversed. Therefore, even in an environment where hot water is supplied to the first inlet flow path (P1a) and cold water is supplied to the second inlet flow path (P1b), the user can use the faucet (10) in the same way. In FIG. 20, arrow ① represents the delivery path of cold water, and arrow ② represents the delivery path of hot water. For reference, since the structure of the flow rate controller (150) corresponds to the structure of the temperature controller (140), a number in the 150 range is assigned, and a detailed explanation is omitted.

[0210] FIG. 21 illustrates the rear structure of the control knob (300). As shown in FIG. 21, the control knob (300) can be rotated counterclockwise (arrow direction ①) or clockwise (arrow direction ②) with respect to FIG. 21. At this time, the rotation axis of the control knob (300) becomes the knob axis (RS, illustrated in FIG. 24). The knob axis (RS) can be formed concentrically with the holder boss portion (362, illustrated in FIG. 19) of the knob holder (360) to be described below. The holder boss portion (362) is a part that is coupled to the controller coupling portion (147) of the temperature controller (140) and can serve as the rotation center (C) of the control knob (300). The control knob (300) can rotate relative to the casing (20) while rotating around the knob axis (RS). For reference, in FIG. 21, reference numeral C represents the center of rotation that is the center of the knob axis (RS). Hereinafter, the axial direction refers to the direction in which the center of rotation (C) is extended.

[0211] The above-mentioned control knob (300) rotates the temperature controller (140) through rotational movement. More precisely, the control knob (300) rotates the control rotor of the temperature controller (140) to control the amount of cold water and hot water mixed. Since the operation process of the temperature controller (140) has been explained previously, a detailed explanation will be omitted.

[0212] All or part of the adjustment knob (300) protrudes outside the casing (20). Since the adjustment knob (300) protrudes outside the casing (20), the user can grasp and rotate it. In this embodiment, the entire adjustment knob (300) protrudes forward of the front plate (40). As another example, a part of the adjustment knob (300) may be placed inside the casing (20).

[0213] The above adjustment knob (300) may move along the axial direction of the knob axis (RS) to have a plurality of axial positions. At this time, the adjustment knob (300) may be rotated around the knob axis (RS) by different angle ranges at the plurality of positions. The adjustment knob (300) may be rotated to a state forming a first distance from the surface of the casing (20) with respect to the axial direction (see FIG. 25), or the adjustment knob (300) may be rotated to a state forming a second distance from the surface of the casing (20) that is closer than the first distance with respect to the axial direction (see FIG. 26).

[0214] In this embodiment, the control knob (300) has a first operating position that is spaced apart from the casing (20) by a first distance with respect to the direction of the knob axis (RS) and can be rotated by a first angle range (AR1, illustrated in FIG. 27) around the knob axis (RS). The control knob (300) has a second operating position that is moved from the first operating position in the axial direction of the knob axis (RS) and is spaced apart from the casing (20) by a second distance. In the second operating position, the control knob (300) is allowed to rotate further by a second angle range (AR2, illustrated in FIG. 27) around the knob axis (RS) from the end of the first angle range (AR1).

[0215] Here, the first angle range (AR1) refers to a limited range of rotation angles for purposes such as preventing safety accidents. The second angle range (AR2) refers to a range of rotation angles that can be rotated further beyond the first angle range (AR1). For example, if the water temperature is set to 40°C in the first angle range (AR1), the water temperature can be set to 60°C in the second angle range (AR2).

[0216] In this embodiment, the adjustment knob (300) is located relatively further from the casing (20) with respect to the axial direction than at the first operating position compared to the second operating position. As another example, the adjustment knob (300) may be located relatively further from the casing (20) with respect to the axial direction at the second operating position.

[0217] Referring to FIG. 21, the first angle range (AR1) and the second angle range (AR2) can be formed by an adjustment slot (326) formed in the adjustment knob (300). The adjustment slot (326) includes a first adjustment slot (326a) that forms the first angle range (AR1) and a second adjustment slot (326b) that forms the second angle range (AR2). The first adjustment slot (326a) and the second adjustment slot (326b) can be connected to each other. The rotation limiting part (47) can limit the rotation angle range of the adjustment knob (300) by interfering with one end of the first adjustment slot (326a) at the first operating position. This structure will be explained in detail below.

[0218] As shown in FIG. 21, a rotary coupler (340) may be exposed on the rear surface of the control knob (300). The rotary coupler (340) is coupled to a knob holder (360). A knob connecting portion (345) for coupling with the knob holder (360) is recessed in the rotary coupler (340). A holder boss portion (365, shown in FIG. 23) of the knob holder (360), which will be described below, is inserted into the knob connecting portion (345), so that the rotational force of the rotary coupler (340) can be transmitted to the knob holder (360). As previously described, since the knob holder (360) is coupled to the temperature controller (140), the rotary coupler (340) is consequently connected to the temperature controller (140) via the knob holder (360).

[0219] As such, the rotary coupler (340) is coupled with the knob holder (360) to (i) maintain the state in which the control knob (300) is coupled to the front of the casing (20), (ii) transmit rotational force to the knob holder (360) and the temperature controller (140) while rotating together with the control knob (300), and (iii) guide the linear movement of the knob body (NB) in the forward and backward directions while maintaining a fixed position relative to the axial direction. This structure will be explained again below.

[0220] FIGS. 22 and FIGS. 23 illustrate the structure of the control knob (300) in an exploded view. For reference, FIG. 22 also illustrates a part of the casing (20). FIG. 22 shows the knob holder (360) mounted on the casing (20), while FIG. 23 shows the knob holder (360) separated from the casing (20). As shown here, the control knob (300) can be positioned in front of the front plate (40) so as to be detachable from the casing (20). The control knob (300) can be separated forward from the casing (20) without disassembling the casing (20) and the front plate (40). In this embodiment, the control knob (300) and the knob holder (360) are coupled to each other by the magnetic force of a magnet. This structure will be explained again below.

[0221] Referring to FIG. 22, a control knob (300) is shown separated from the front of the knob holder (360) and with each part disassembled. Even if the control knob (300) is separated, the knob holder (360) can remain connected to the temperature controller (140). As another example, the knob holder (360) may also be separated from the temperature controller (140) together with the control knob (300). In this case, the knob holder (360) may also be considered as a part constituting the control knob (300).

[0222] The above-mentioned control knob (300) may include a knob body (NB) and a rotary coupler (340). At this time, the knob body (NB) and the rotary coupler (340) may rotate together. However, the knob body (NB) and the rotary coupler (340) do not move together in the forward and backward directions. More precisely, the knob body (NB) moves linearly backward toward the front plate (40) and forward oppositely, but the rotary coupler (340) does not move together and remains fixed axially to the knob holder (360). That is, the knob body (NB) and the rotary coupler (340) move linearly relative to each other.

[0223] The skeleton of the above-mentioned adjustment knob (300) can be formed by the knob body (NB). The knob body (NB) is the part exposed to the outside of the casing (20). The knob body (NB) may have a thin cylindrical shape and a dial shape. As another example, the knob body (NB) may have various shapes, such as a polygonal shape or an elliptical shape, based on the front view.

[0224] The knob body (NB) may include a knob cover (310) having an internal mounting space (312, illustrated in FIG. 23) and a knob core (320) positioned in the mounting space (312). The knob core (320) operates together with the knob cover (310), and its axial movement is guided by the rotary coupler (340). The part that the user grips is the surface of the knob cover (310), and since the knob core (320) is positioned inside the knob body (NB), it is not actually exposed to the user. The knob cover (310) and the knob core (320) can be combined to form a single dial body (DB).

[0225] Looking at the knob cover (310) above, the side of the knob cover (310) can form a gripping portion (311). The gripping portion (311) becomes a surface that the user grips. In this embodiment, the gripping portion (311) has an uneven structure. The gripping portion (311) can also be viewed as the outer surface of the knob cover (310).

[0226] A mounting slot (313) may be formed in the knob cover (310). The mounting slot (313) is formed by penetrating the knob cover (310). An indicator (330), which will be described later, is mounted in the mounting slot (313). Corresponding to the shape of the indicator (330), the mounting slot (313) may have a roughly "L" shape. More precisely, the mounting slot (313) is formed such that a first mounting slot (313a) and a second mounting slot (313b) are connected in directions perpendicular to each other. The first mounting slot (313a) is open in the front-rear direction and can accommodate most of the indicator (330). The second mounting slot (313b) is open in the up-down direction and can accommodate the alignment protrusion (333) of the indicator (330). Drawing symbol 430 represents the indicator of the second control knob (400).

[0227] Referring to FIG. 23, the knob cover (310) may be provided with a body sleeve (315). The body sleeve (315) protrudes rearward from the center of the knob cover (310). The body sleeve (315) includes a sleeve groove (316) which is an empty space in the center. An insertion projection (331) of the knob cover (310) and the indicator (330) is inserted into the sleeve groove (316). A cover fastener (B5) for assembly between the indicator (330) and the knob cover (310) is fastened to the fastening groove (331a) of the insertion projection (331).

[0228] The body sleeve (315) can be coupled with the coupler sleeve (342, illustrated in FIG. 22) of the rotary coupler (340). The body sleeve (315) and the coupler sleeve (342) can form a concentric structure and form the center of rotation (C) of the control knob (300). As shown in FIG. 24, the center of rotation (C) of the control knob (300) passes through the center of the body sleeve (315) and the coupler sleeve (342). Therefore, the body sleeve (315) and the coupler sleeve (342) can be viewed as the knob axis (RS, see FIG. 24) of the control knob (300). If the knob holder (360) is also considered as part of the control knob (300), the holder boss (362) can be viewed as the knob axis of the control knob (300). Drawing reference numeral 343 is a sleeve space formed on the inner side of the coupler sleeve (342), and a part of the elastic member (350) may be placed in the sleeve space (343).

[0229] The coupler sleeve (342) wraps around the surface of the body sleeve (315), and the body sleeve (315) and the coupler sleeve (342) rotate together when the control knob (300) is rotated. The body sleeve (315) and the coupler sleeve (342) overlap each other to help with axial alignment between the knob body (NB) and the rotary coupler (340). As another example, either the body sleeve (315) or the coupler sleeve (342) may be omitted. As yet another example, the body sleeve (315) and the coupler sleeve (342) may be directly coupled to the temperature controller (140).

[0230] The knob cover (310) may be provided with a catch rib (317). The catch rib (317) is for joining the knob cover (310) and the knob core (320). The catch rib (317) may be positioned around the opening edge of the mounting space (312) in the knob cover (310). The catch rib (317) protrudes radially toward the body sleeve (315). The catch rib (317) engages with the catch projection (323a) of the knob core (320), which will be described below, to prevent the knob core (320) from separating axially from the knob cover (310).

[0231] Looking at the knob core (320), the knob core (320) may have a roughly ring shape. A core hole (322) is formed in the center of the knob core (320). The rotary coupler (340) may be disposed in the core hole (322). In this embodiment, the length of the knob core (320) in the front-rear direction is shorter than the length of the rotary coupler (340) in the front-rear direction. Accordingly, during the movement of the knob body (NB) in the front-rear direction, the knob core (320) may not move away from the rotary coupler (340).

[0232] The knob core (320) is placed in the mounting space (312) so that it is not exposed unless the control knob (300) is separated from the faucet (10). The knob core (320) can form a knob body (NB) together with the knob cover (310). The knob core (320) engages with the rotary coupler (340) to transmit the rotational force of the knob body (NB) to the rotary coupler (340).

[0233] The knob core (320) can serve to (i) limit the rotational angle range of the control knob (300), (ii) guide the linear movement of the knob body (NB) in the forward and backward directions, and (iii) reinforce the strength of the knob body (NB). Limiting the rotational angle range of the control knob (300) can be achieved by the control slot (326) formed in the knob core (320). Guiding the linear movement of the knob body (NB) in the forward and backward directions can be achieved by the guide slot (329) of the knob core (320). As such, in this embodiment, the knob core (320) handles the relatively complex shape, and the knob cover (310) is implemented in a relatively simple form, thereby enhancing the aesthetic appeal of the control knob (300). This structure will be explained again below.

[0234] The knob core (320) may be provided with a ring-shaped core ring (321). The core ring (321) forms the framework of the knob core (320). The outer surface of the core ring (321) becomes the outer surface of the knob core (320). The outer surface of the knob core (320) may face the inner surface of the mounting space (312). That is, the outer surface of the knob core (320) faces the inner surface of the knob cover (310). At this time, the outer surface of the knob core (320) and the inner surface of the knob cover (310) may form a spaced-apart portion from each other. Accordingly, as shown in FIG. 24, a spaced-apart space (IS) is formed between the knob cover (310) and the knob core (320).

[0235] The above-mentioned separation space (IS) can be opened in the axial direction toward the surface of the casing (20). Here, the direction toward the surface of the casing (20) is the rear with respect to FIG. 24. Although the rear of the separation space (IS) is depicted in the drawing as being blocked by the catch rib (317), the catch rib (317) is provided intermittently, so the separation space (IS) can be opened to the rear. Moisture or foreign matter inside the separation space (IS) can be discharged through this open part. In FIG. 24, arrow ① indicates the direction in which moisture inside the separation space (IS) is discharged.

[0236] More specifically, the above-mentioned separation space (IS) is open toward the surface of the casing (20), that is, toward the front plate (40). When the adjustment knob (300) moves linearly forward or backward, the rotary coupler (340) and the knob body (NB) move relative to each other, and the volume of the operating space, which is the empty space formed between the rotary coupler (340) and the knob body (NB), changes. Here, the operating space includes the area between the surface (311a) constituting the rear of the knob cover (310) and the rotary coupler (340), and the mounting space (312) can be considered as the operating space.

[0237] Since the above operating space is also connected to the above separation space (IS), such a change in volume can change the pressure of the above separation space (IS). The above separation space (IS) is formed between the knob cover (310) and the knob core (320), and the above separation space (IS) is connected to the above operating space through the gap between the knob cover (310) and the knob core (320). When the pressure of the above separation space (IS) changes in this way, moisture, etc. that has entered the above separation space (IS) is discharged to the rear. Of course, foreign substances such as moisture that have entered the above operating space can also be discharged to the outside of the control knob (300) by this change in pressure. That is, moisture, etc. inside the control knob (300) is naturally discharged during the process of the user pressing or pulling the above control knob (300). As described below, since the control knob (300) is moved forward by the elastic member (350), as a result, the user can remove moisture from the control knob (300) by simply pressing the control knob (300).

[0238] Referring again to FIG. 23, a core coupling portion (323) is provided on the outer surface of the core ring (321). The core coupling portion (323) is for coupling between the knob core (320) and the knob cover (310). The core coupling portion (323) protrudes from the outer surface of the core ring (321). The core coupling portion (323) may include a pair of rib structures protruding from the surface of the core ring (321). The indicator (330) may be coupled to the protruding core coupling portion (323).

[0239] Looking more closely, the core coupling portion (323) may form a groove structure extending in the front-rear direction. The core coupling portion (323) creates a groove that is open forward, and the alignment protrusion (333) of the indicator (330) enters into this groove. When the indicator (330) passes through the second mounting slot (313b) of the knob cover (310) and is coupled to the core coupling portion (323), the knob cover (310) and the knob core (320) are coupled by the indicator (330) so that they do not rotate relative to each other. Accordingly, the knob cover (310) and the knob core (320) can rotate together.

[0240] A catch projection (323a) may be provided on the outer surface of the core ring (321). In this embodiment, the catch projection (323a) is provided at a position adjacent to the core coupling portion (323). The catch projection (323a) may be positioned further back than the core coupling portion (323). The catch projection (323a) extends circumferentially along the outer surface of the core ring (321). The catch projection (317) of the knob cover (310) may engage with the catch projection (323a). More precisely, when the knob cover (310) moves backward with reference to FIG. 23, the knob core (320) is inserted into the mounting space (312). At this time, the catch projection (317) may be moved at a rotated angle so as not to interfere with the core coupling portion (323).

[0241] After the knob core (320) is inserted into the mounting space (312), when the knob cover (310) is rotated (counterclockwise with respect to FIG. 23), the locking rib (317) is positioned behind the locking jaw (323a). In this way, the locking rib (317) and the locking jaw (323a) are engaged with each other in the axial direction, preventing axial separation. Looking at FIG. 24, the locking jaw (323a) is relatively forward and the locking rib (317) is relatively backward. Accordingly, the knob cover (310) cannot be separated forward from the knob core (320).

[0242] In FIGS. 23 and 24, reference numeral 323b represents a limiting projection for limiting the range of relative rotation of the knob cover (310) to the knob core (320) during the process of assembling the knob cover (310) to the knob core (320). The locking rib (317) engages with the limiting projection (323b), thereby allowing the assembly angle between the knob cover (310) and the knob core (320) to be set.

[0243] At this time, as previously explained, when the indicator (330) is assembled to the knob cover (310), the indicator (330) prevents relative rotation between the knob cover (310) and the knob core (320), so that, as a result, both relative rotation and relative linear movement of the knob cover (310) and the knob core (320) can be prevented. That is, when the indicator (330) is coupled to the adjustment knob (300) in the axial direction, the indicator (330) can engage the knob cover (310) and the knob core (320) respectively to limit the relative rotation between the knob cover (310) and the knob core (320). Therefore, the indicator (330) itself can act as a kind of fastener without the need for a separate fastener.

[0244] Referring to FIGS. 23 and 24, the knob core (320) may be provided with a rotation guide (325). The rotation guide (325) surrounds the core hole (322) and has a ring shape. The rotation guide (325) has a smaller diameter than the core ring (321) of the knob core (320). Accordingly, the core ring (321) and the rotation guide (325) are spaced apart from each other. The adjustment slot (326) is formed in this spaced-apart portion. The adjustment slot (326) is formed along the circumferential direction of the knob core (320) between the core ring (321) and the rotation guide (325). The rotation limiting part (47) is inserted into the adjustment slot (326). The structure of the adjustment slot (326) will be explained again below.

[0245] A stepped portion (327) may be provided between the first adjustment slot (326a) and the second adjustment slot (326b) constituting the adjustment slot (326). The stepped portion (327) interferes with the rotation limiting portion (47). The stepped portion (327) protrudes from the core ring (321) in a direction that narrows the diameter of the adjustment slot (326), that is, in the direction toward the center of the knob core (320). When the rotation limiting portion (47) engages with the stepped portion (327), the rotation of the entire adjustment knob (300) is restricted. In this embodiment, two stepped portions (327) are arranged in the knob core (320) so as to be spaced apart from each other in the circumferential direction. The structure of such stepped portions (327) will be explained again below.

[0246] A guide slot (329) may be formed in the rotation guide (325). The guide slot (329) is formed in a shape in which a part of the rotation guide (325) is cut in the front-rear direction. A guide rib (349) of a rotation coupler (340), which will be described later, is inserted into the guide slot (329). When the guide slot (329) and the guide rib (349) are coupled to each other in the axial direction, the knob body (NB) can move in the axial direction along the guide rib (349). That is, when the knob body (NB) moves in the front-rear direction, it can move in a straight line without rotating relative to the rotation coupler (340). In this process, the knob body (NB) can move between a first operating position (state in FIG. 25) and a second operating position (state in FIG. 26). The first operating position and the second operating position will be described later.

[0247] Referring to FIG. 22, the indicator (330) is shown separated from the knob body (NB). The indicator (330) allows the user to check the rotation angle of the knob body (NB). To this end, the indicator (330) may be coupled to the knob body (NB) and may protrude or be exposed to the outside of the knob body (NB). As another example, the indicator (330) may be integrally provided with the knob body (NB).

[0248] The indicator (330) is mounted in the first mounting slot (313a) and the second mounting slot (313b). The indicator (330) may include a fastening protrusion (331) inserted into the center of the knob body (NB) and an alignment protrusion (333) placed in the second mounting slot (313). As shown in FIG. 24, the fastening protrusion (331) is fastened to the knob cover (310) by a cover fastener (B5). Reference numeral 331a is an assembly groove formed in the center of the fastening protrusion (331), and the cover fastener (B5) is fastened to the assembly groove (331a). As another example, the indicator (330) may be press-fitted or bonded to the knob body (NB).

[0249] The alignment protrusion (333) can be inserted into the second mounting slot (313) and coupled to the knob core (320). Coupling means that the alignment protrusion (333) is fitted into the core coupling portion (323, shown in FIG. 23) of the knob core (320). In this way, the alignment protrusion (333) restricts the independent rotation of the knob core (320), so that the knob core (320) can rotate together with the knob cover (310) and the indicator (330).

[0250] In this embodiment, the alignment protrusion (333) protrudes further outwardly in a radial direction from the knob body (NB). The user may detect the rotational state of the adjustment knob (300) by looking at the protruding alignment protrusion (333). Additionally, the user may grip the adjustment knob (300) more comfortably by utilizing the protruding structure of the alignment protrusion (333).

[0251] Referring to FIGS. 22 and FIGS. 23, the rotary coupler (340) has a roughly cylindrical shape. The rotary coupler (340) is positioned between the knob body (NB) and the knob holder (360) to transmit the rotational force of the knob body (NB) to the knob holder (360). The rotary coupler (340) can only rotate and not move in a straight line.

[0252] The coupler body (341) forming the frame of the rotary coupler (340) may have a roughly ring shape. The coupler body (341) is placed in the core hole (322) of the knob core (320). A coupler sleeve (342) is provided at the center of the coupler body (341). The coupler sleeve (342) may protrude forward, and a sleeve hole (342a), which is an empty space, may be formed at the center. The body sleeve (315) of the knob body (NB) may be inserted into the sleeve hole (342a).

[0253] The coupler body (341) and the coupler sleeve (342) have different diameters. Accordingly, the coupler body (341) and the coupler sleeve (342) are spaced apart from each other, so that a portion of the elastic member (350) can be accommodated between them. Referring to FIG. 24, one end of the elastic member (350) is positioned between the coupler body (341) and the coupler sleeve (342), and the other end is in close contact with the surface (311a) of the knob cover (310). Accordingly, the elastic member (350) provides elastic force to the knob body (NB) in a direction away from the rotating coupler (340) with respect to the axial direction. That is, the elastic member (350) can provide elastic force to the adjustment knob (300) in a direction from the second operating position toward the first operating position.

[0254] A knob fastening portion (345) may be recessed into the rotary coupler (340). The knob fastening portion (345) is recessed in the axial direction. A holder boss portion (365) of a knob holder (360) is inserted into the knob fastening portion (345). When the holder boss portion (365) is inserted into the knob fastening portion (345), the rotary coupler (340) and the knob holder (360) engage with each other to transmit rotational force.

[0255] The knob fastening portion (345) may extend radially from the rear surface of the rotary coupler (340). In this embodiment, the knob fastening portion (345) includes a plurality of knob fastening portions (345) that extend radially. A sleeve hole (342a) penetrating the coupler sleeve (342) is connected at the center where the plurality of knob fastening portions (345) are connected. As another example, the knob fastening portion (345) may have a protruding shape, and the holder fastening portion (365) may have a recessed structure. As yet another example, a separate fastening member may be assembled axially or radially between the rotary coupler (340) and the knob holder (360) so that they can rotate together.

[0256] The rotary coupler (340) may be provided with a stopper (346). The stopper (346) engages the knob body (NB) to limit the axial movement distance of the knob body (NB). The stopper (346) protrudes radially from the edge of the coupler body (341). The stopper (346) may be continuous in a circumferential direction along the edge of the coupler body (341). The stopper (346) engages the end (325a, shown in FIG. 19) of the rotary guide of the knob core (320) to prevent the knob body (NB) from being separated forward from the rotary coupler (340).

[0257] In FIG. 24, the stopper (346) is not visible due to the angle of the cross-section, but in FIG. 19, the stopper (346) can be seen engaging the knob core (320). The stopper (346) prevents axial separation of the knob body (NB), and the knob holder (360) prevents axial separation of the rotary coupler (340) through the magnetic coupling parts (M1, M2) to be described later. As a result, the knob body (NB) is not completely separated from the knob holder (360) and can move and rotate axially while positioned in front of the knob holder (360).

[0258] Referring to FIG. 22, the rotary coupler (340) can be assembled to the knob core (320) in a positioned between the knob cover (310) and the knob core (320). During the process of assembling the rotary coupler (340) to the knob core (320), the stopper (346) may catch on the end (325a) of the knob core (320), thereby limiting the assembly depth. With the rotary coupler (340) fitted into the knob core (320), when the knob cover (310) is coupled to the knob core (320) on the opposite side of the knob core (320), the rotary coupler (340) is assembled between the knob core (320) and the knob cover (310). Of course, as previously described, the knob body (NB) and the rotary coupler (340) are assembled to each other in a state where they can move relative to one another in the axial direction.

[0259] Referring again to FIG. 24, the coupling between the knob holder (360) and the rotary coupler (340) can be achieved by magnetic coupling parts (M1, M2). The magnetic coupling parts (M1, M2) include a first magnetic coupling part (M1) disposed on the rotary coupler (340) and a second magnetic coupling part (M2) disposed on the knob holder (360). At least one of the first magnetic coupling part (M1) and the second magnetic coupling part (M2) may be composed of a permanent magnet. The other of the first magnetic coupling part (M1) and the second magnetic coupling part (M2) may be a permanent magnet or may be composed of a ferromagnetic material. Reference numeral CL indicates a contact surface where the knob holder (360) and the rotary coupler (340) are in close contact with each other by the magnetic coupling parts (M1, M2).

[0260] The first magnetic coupling part (M1) and the second magnetic coupling part (M2) generate an attractive force in the axial direction relative to each other. Accordingly, the knob holder (360) can pull and fix the rotary coupler (340) and the knob body (NB) in the axial direction. The first magnetic coupling part (M1) is inserted into the first component storage groove (347) formed in the rotary coupler (340). The second magnetic coupling part (M2) is inserted into the second component storage groove (367) of the knob holder (360), which will be described later. These are aligned in the axial direction relative to each other, thereby increasing the magnitude of the magnetic force.

[0261] A guide rib (349) may be provided on the outer surface of the rotary coupler (340). The guide rib (349) protrudes from the outer surface of the rotary coupler (340) and extends in the front-rear direction. The guide rib (349) is fitted into the guide slot (329) of the knob core (320). When the guide slot (329) and the guide rib (349) are coupled to each other in the axial direction, the knob body (NB) can be moved axially along the guide rib (349).

[0262] Looking at the knob holder (360) above, the knob holder (360) connects the temperature controller (140) and the control knob (300). The knob holder (360) is coupled to the temperature controller (140) and simultaneously coupled to the control knob (300). Accordingly, the rotational force of the control knob (300) is transmitted to the temperature controller (140). As shown in FIG. 22, the knob holder (360) is coupled to the temperature controller (140), and at least a portion of it is exposed to the front of the front plate (40).

[0263] Referring to FIG. 23, the knob holder (360) may be provided with a holder body (361) in the shape of a roughly disc. The outer surface of the holder body (361) is not protruded forward of the front plate (40) and is positioned inside the casing (20). The knob holder (360) is fixed to the casing (20) while coupled to the temperature controller (140). Even if the control knob (300) is separated from the casing (20), the knob holder (360) remains fixed to the casing (20).

[0264] The knob holder (360) may be provided with a holder boss portion (362). The holder boss portion (362) protrudes rearward toward the temperature controller (140). The holder boss portion (362) may have a cylindrical shape. The holder boss portion (362) is for coupling with the temperature controller (140), and a boss hole (363) is formed in the center. Serrations may be formed on the inner surface of the boss hole.

[0265] Referring to FIG. 19, the knob holder (360) may be positioned inside the temperature control mounting part. The knob holder (360) is connected to the temperature controller (140) inside the temperature control mounting part. A knob fastener (B6) is fastened to the fastening hole (363) of the holder fastening part (362) to connect the holder fastening part (362) and the head coupling part (147) of the temperature controller (140). In this way, the holder fastening part (362) can serve as the rotation axis of the control knob (300).

[0266] Referring again to FIG. 22, a holder boss portion (365) may be provided on the front of the knob holder (360). The holder boss portion (365) engages with the knob connecting portion (345) of the rotary coupler (340). By engaging with the knob connecting portion (345), the holder boss portion (365) can receive the rotational force of the rotary coupler (340). The holder boss portion (365) protrudes forward from the knob holder (360). In this embodiment, the holder boss portion (365) extends radially from the center of the knob holder (360). The holder boss portion (365) may be composed of a plurality of holder boss portions (365), and in this embodiment, a total of three holder boss portions (365) protrude from the front of the knob holder (360).

[0267] The above-mentioned control knob (300) can move between a first operating position and a second operating position. FIG. 25 shows the control knob (300) in the first operating position, and FIG. 26 shows the control knob (300) in the second operating position. In FIG. 25, the control knob (300) and the front plate (40) are spaced apart by a first distance from each other to secure an operating space (G1). More precisely, the operating space (G1) is formed between the rear of the knob body (NB) and the front plate (40). In this way, when the control knob (300) moves from the first operating position to the second operating position, the axial distance between the control knob (300) and the casing (20) changes. In this embodiment, the adjustment knob (300) is positioned closer to the casing (20) in the axial direction at the second operating position than at the first operating position.

[0268] In the state of FIG. 25, when the user presses the knob body (NB) backward along the direction of arrow P, the knob body (NB) retracts and moves to a second operating position. That is, the knob body (NB) can move in a direction that narrows the operating space (G1). As shown in FIG. 26, the operating space (G1) is filled by the knob body (NB). At this time, the user can press the knob body (NB) while overcoming the elastic force of the elastic member (350), and when the pressing force is removed, the adjustment knob (300) moves back to the first operating position by the elastic member (350).

[0269] When the above adjustment knob (300) is moved from the first operating position to the second operating position by moving along the axis of the knob axis (RS), the adjustment knob (300) can be rotated further by the second angle range (AR2) around the knob axis (RS) from the end of the first angle range (AR1). At the second operating position, the adjustment knob (300) may rotate both the first angle range (AR1) and the second angle range (AR2). This structure will be explained below.

[0270] Although not shown, the above-mentioned water tap (10) may be equipped with a detection sensor. The detection sensor may detect that the control knob (300) has been moved to the second operating position. When the detection sensor detects that the control knob (300) has been moved to the second operating position, the control device may display this through the display. Alternatively, the control device may notify the user's terminal through the communication means.

[0271] Referring to FIG. 27, the rear structure of the control knob (300) is illustrated. As shown in the figure, the control slot (326) of the knob body (NB) is opened to the rear. The control slot (326) includes a first control slot (326a) and a second control slot (326b). The first control slot (326a) forms the first angle range (AR1). The second control slot (326b) is connected to the first control slot (326a) and forms the second angle range (AR2). The first control slot (326a) and the second control slot (326b) can form a continuous path with each other. Here, the first angle range (AR1) and the second angle range (AR2) each represent the range in which the control knob (300) rotates around the knob axis (RS).

[0272] The second angle range (AR2) above may be used when a higher temperature water is desired because the amount of hot water mixed is greater than that of the first angle range (AR1). In this embodiment, the first angle range (AR1) is wider than the second angle range (AR2). As another example, the second angle range (AR2) may be wider than the first angle range (AR1). As yet another example, the sum of the first angle range (AR1) and the second angle range (AR2) shown in FIG. 27 may be referred to as the second angle range (AR2).

[0273] The above-mentioned control knob (300) may further include a third angle range (AR3). The third angle range (AR3) may be formed on the opposite side of the second angle range (AR2) centered on the first angle range (AR1). The third angle range (AR3) may be used to control the amount of cold water mixed. As another example, the third angle range (AR3) may be omitted. As yet another example, the third angle range (AR3) may be formed adjacent to the second angle range (AR2) and continuously from the second angle range (AR2).

[0274] The first angle range (AR1) and the second angle range (AR2) can form a continuous path along the rotational direction of the control knob (300). When the control knob (300) is rotated, the rotation limiting part (47, not shown in FIG. 27) moves relative to the control knob (300) along the first angle range (AR1). At the boundary between the first angle range (AR1) and the second angle range (AR2), the rotation limiting part (47) interferes with one end of the first control slot (326a). More precisely, at the first operation position, the rotation limiting part (47) interferes with one end of the first control slot (326a). At the second operation position, the rotation limiting part (47) is released from interference with one end of the first control slot (326a) and can enter the second angle range (AR2).

[0275] As another example, the first angle range (AR1) and the second angle range (AR2) may overlap at least partially. The first angle range (AR1) and the second angle range (AR2) may form a continuous path, but may also have a structure that shares the overlapping range.

[0276] In FIG. 27, when the control knob (300) is rotated in the direction of arrow ②, the relatively fixed rotation limiting part (47, not shown in FIG. 27) moves along the first angle range (AR1). After the control knob (300) moves to the second operating position, if the control knob (300) continues to rotate in the direction of arrow ②, the rotation limiting part (47) moves along the second angle range (AR2). During this process, the temperature of the water discharged to the outlet parts (OH1, OH2) may gradually increase. Conversely, in FIG. 27, when the control knob (300) is rotated in the direction of arrow ①, the temperature of the water may gradually decrease.

[0277] A stepped portion (327) may be formed on the above-mentioned adjustment knob (300). The stepped portion (327) is formed in the adjustment slot (326). The stepped portion (327) may be formed at the boundary portions of a plurality of angle ranges. In this embodiment, a first stepped portion (327A) is formed between the first angle range (AR1) and the second angle range (AR2), and a second stepped portion (327B) is formed between the first angle range (AR1) and the third angle range (AR3). As another example, the second stepped portion (327B) may be omitted and only the first stepped portion (327A) may be formed on the adjustment knob (300).

[0278] Based on the above step portion (327), the distance from the knob axis (RS), which is the rotation center of the control knob (300), to the surface (inner surface) of the control slot (326) along the radial direction may be formed differently. More precisely, as shown in FIG. 27, the radial distance from the rotation center (C) of the control knob (300) to the inner surface of the first control slot (326a) forms a first distance (R1). The radial distance from the rotation center (C) of the control knob (300) to the inner surface of the second control slot (326b) forms a second distance (R2). The above step portion (327) may be formed between the first surface (S1) and the second surface (S2).

[0279] FIGS. 28 to 31 illustrate the adjustment knob (300) being rotated. For reference, the adjustment knob (300) is viewed from the front in FIGS. 28(a) to 31(a), and the adjustment knob (300) is viewed from the rear in FIGS. 28(b) to 31(b). FIGS. 28 to 31 also illustrate the state in which the rotation limiting part (47) is inserted into the adjustment slot (326).

[0280] First, looking at FIG. 28, the control knob (300) is rotated clockwise (arrow direction ①) to show a state where the amount of cold water mixed in the temperature controller (140) is greater. When the control knob (300) is rotated clockwise and the amount of cold water mixed increases, the temperature of the water discharged from the outlets (OH1, OH2) can be set lower. Arrow direction ② indicates the direction in which the control knob (300) is rotated counterclockwise to increase the water temperature.

[0281] At this time, the adjustment knob (300) can be rotated clockwise within a second angle range (AR2). In the state of FIG. 28, the adjustment knob (300) may be rotated further clockwise. That is, the adjustment knob (300) can be rotated further beyond the previously described second angle range (AR2) by a third angle range (AR3). To do this, the adjustment knob (300) needs to move from a first operating position to a second operating position.

[0282] Referring to FIG. 29, the control knob (300) is rotated in the opposite direction, counterclockwise (arrow direction ①), to set the amount of hot water mixed high. When the control knob (300) rotates while the rotation limiting part (47) is fixed, the rotation limiting part (47) rotates relative to the first control slot (326a). During this process, the rotation limiting part (47) gets caught on the first step part (327A) and is prevented from rotating further at the end of the first control slot (326a). FIG. 29(b) shows the limiting head (47a) protruding from the rotation limiting part (47) getting caught on the first step part (327A).

[0283] In this state, if the user wishes to use water at a higher temperature, the control knob (300) must be rotated further counterclockwise (direction of arrow ①). To do this, the restricted state of the control knob (300) must first be released. Here, the restricted state refers to a state in which the control knob (300) is caught by the rotation limiting part (47) and can no longer be rotated in the same direction. This restricted state can be released by moving the control knob (300) from the first operating position to the second operating position.

[0284] FIG. 30 illustrates the adjustment knob (300) moved to the rear (direction of arrow ①). When the adjustment knob (300) is moved to the rear, it is positioned in the second operating position. Accordingly, as shown in FIG. 30(b), the fixed rotation limiting part (47) is moved relatively forward. When this happens, the limiting head (47a) is released from the state of being caught on the first step part (327A).

[0285] FIG. 31 illustrates the state in which the control knob (300), moved to the second operating position, is further rotated counterclockwise (direction of arrow ①). As shown in FIG. 31(b), the rotation limiting part (47) can move out of the first control slot (326a) and along the second control slot (326b). That is, the rotation limiting part (47) is rotated within the second angle range (AR2). Accordingly, the user can use water at a higher temperature.

[0286] At this time, the control knob (300) can be further rotated in a counterclockwise direction (direction of arrow ①). When the control knob (300) is further rotated in the direction of arrow ① in the state of FIG. 31(b), the rotation limiting part (47) can be rotated relative to the second control slot (326b) in a counterclockwise direction relative to FIG. 31(b). However, the control knob (300) is provided with a partition (328), so that the rotation limiting part (47) interferes with the partition (328). The partition (328) can limit the maximum rotation angle of the control knob (300). It can also be seen that a plurality of slots constituting the control slot (326) are disconnected relative to the partition (328).

[0287] FIG. 32 is an enlarged view of FIG. 30(b) showing the rotation limiting part (47) released from the restricted state in which it is engaged with the first step part (327A). For better understanding, FIG. 32 shows the knob body (NB) cut to reveal the internal structure of the adjustment slot (326). As can be seen, the limiting head (47a), which protrudes further radially from the rotation limiting part (47), interferes with the first step part (327A). However, when the adjustment knob (300) moves to the second operating position (direction of arrow ①), the limiting head (47a) moves relatively inward into the adjustment slot (326) with respect to the axial direction and can move out of the first step part (327A).

[0288] A movement space (MS) in which the limiting head (47a) can move may be formed inside the adjustment slot (326). The movement space (MS) forms a continuous space along the circumferential direction inside the adjustment slot (326). The axial width (G2) of the movement space (MS) is the distance over which the limiting head (47a) can move relative in the axial direction. When the limiting head (47a) moves relative along this movement space (MS), the limiting head (47a) moves away from the first step portion (327A) and can move to the second limiting slot.

[0289] As shown in FIG. 32, the inner surface of the core ring (321) inside the second adjustment slot (326b) includes parts that differ in radial distance from the center of rotation of the adjustment knob (300). More precisely, the inner surface of the core ring (321) includes parts where the radial distance differs along the axial direction (direction of arrow ①). In the moving space (MS) formed inside the second adjustment slot (326b), the radial distance of the inner surface of the core ring (321) (first surface (S1)) is farther than the radial distance of the inner surface of the core ring (321) (second surface (S2)) at the entrance of the second adjustment slot (326b). At the entrance of the second adjustment slot (326b), the inner surface of the core ring (321) becomes the inner surface of the first stepped portion (327A).

[0290] The limiting head (47a) cannot pass through the relatively narrow entrance of the second adjustment slot (326b). The limiting head (47a) can pass through the entrance of the first adjustment slot (326a) adjacent to the second adjustment slot (326b). The limiting head (47a), having passed through the entrance of the first adjustment slot (326a), rotates relative to face the first surface (S1) of the second adjustment slot (326b).

[0291] FIG. 33 illustrates a control knob (300) constituting a second embodiment of the water tap (10) according to the present invention. Description of parts identical to those in the preceding embodiment will be omitted. In this embodiment, a rotation limiting part (326) that limits the rotation angle range of the control knob (300) may be provided on the control knob (300). The rotation limiting part (326) protrudes axially from the knob core (320) constituting the control knob (300).

[0292] Accordingly, the casing (20) has a limiting slot (47a, 47b) formed therein to guide the rotation of the rotation limiting part (326). The limiting slot (47a, 47b) extends circumferentially along the edge of the knob holder (360). The limiting slot (47a, 47b) may be composed of a plurality of limiting slots. The rotation limiting part (326) can limit the rotation angle range while rotating along the limiting slot (47a, 47b). At this time, if the adjustment knob (300) retracts toward the casing (20) or, conversely, advances toward the casing (20), the adjustment knob (300) may rotate further beyond the rotation angle range by an additional angle range.

[0293] FIG. 34 illustrates the rear structure of a control knob (300) constituting a third embodiment of the water tap (10) according to the present invention. Description of parts identical to those in the preceding embodiment will be omitted. In this embodiment, a control slot (326) is formed in the knob body (NB) of the control knob (300). The control slot (326) includes a first control slot (326a) and a second control slot (326b). In this embodiment, the control slot (326) includes only two angle ranges (AR1, AR2) formed by the first control slot (326a) and the second control slot (326b), and the third angle range is omitted. Reference numeral 328 indicates a partition (328), and the rotation limiting part (47) interferes with each end of the partition (328), thereby restricting further relative rotation.

[0294] The first control slot (326a) and the second control slot (326b) serve to set water to different temperature ranges. When the control knob (300) is rotated, the temperature of the discharged water is varied in the direction of arrow ① or arrow ②. In the drawing, arrow ① is the direction for lowering the water temperature, and arrow ② is the direction for raising the water temperature. For example, when the rotation limiter (47, not shown in FIG. 34) rotates relative to the first control slot (326a), the water temperature is controlled to be below 40°C, and when it rotates relative to the second control slot (326b), the water temperature can be controlled to be above 50°C.

[0295] FIG. 35 illustrates a control knob (300) constituting a fourth embodiment of the water tap (10) according to the present invention. Description of parts identical to those in the preceding embodiment will be omitted. In this embodiment, a rotary coupler (340) that guides the axial linear movement of the knob body (NB) and transmits the rotational force of the knob body (NB) to the temperature controller (140) remains coupled to the temperature controller (140). That is, when the control knob (300) is separated from the temperature controller (140), the rotary coupler (340) remains coupled to the temperature controller (140). As another example, the rotary coupler (340) may be integrally provided with the temperature controller (140). As yet another example, the rotary coupler (340) may be viewed as part of the knob holder (360).

[0296] FIG. 36 illustrates a control knob (300) constituting a fifth embodiment of the water tap (10) according to the present invention. Description of parts identical to those in the preceding embodiment will be omitted. In this embodiment, the knob body (NB) is composed of a single part. The rotation of the knob body (NB) is transmitted to the knob holder (360) via the rotation coupler (340). A structure for limiting the rotation angle range of the knob body (NB), for example, a control slot (326, not shown in FIG. 36), may be integrally formed in the knob body (NB).

[0297] In another embodiment, although not illustrated, at least one of the flow regulator (150), the filter (160), the generator (170), and the water outlet selector (190) may be omitted.

[0298] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by such embodiments. The scope of protection of the present invention shall be interpreted by the claims below, and all technical concepts within an equivalent scope shall be interpreted as being included within the scope of rights of the present invention.
