More specifically, the present invention relates to a faucet device comprising: a water discharge pipe provided with two branch pipe portions, which discharges water simultaneously from water discharge ports respectively provided in the branch pipe portions; and a water supply pipe connected in flow communication with the water discharge pipe to enable water supply to the water discharge pipe. [Background Art]

[0002] Patent Document 1 discloses a faucet device in which a water discharge pipe is bifurcated on the downstream side of a water stop valve, and water is discharged from each of the branch pipe portions. [Prior Art Documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2008-295675 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] In the configuration described in Patent Document 1, when the shape of each branch pipe portion is asymmetric or varies, distribution adjustment for equalizing the discharge flow rate of each branch pipe portion cannot be performed. Accordingly, the present invention provides a faucet device that can easily adjust the discharge flow rate distributed to each branch pipe portion. [Means for Solving the Problem]

[0005] To solve the above problems, the faucet device of the present invention takes the following measures. That is, the first invention of the present invention is a faucet device comprising a discharge pipe including a connecting pipe section having a connection port opening in the direction of the pipe axis, two branch pipe sections branching from the connecting pipe section in a direction intersecting the direction of the pipe axis and discharging water simultaneously from their respective discharge ports, and a water supply pipe connected to the connecting pipe section in a flow path so as to be able to supply water, wherein the water supply pipe has a connected pipe section that is flow path connected to the connecting pipe section in the direction of the pipe axis, and a curved pipe section that bends from the connected pipe section in a direction intersecting the direction of the pipe axis, and the faucet device further has an adjustment mechanism that can adjust the bending direction of the curved pipe section of the water supply pipe relative to the connecting pipe section around the pipe axis of the connecting pipe section.

[0006] According to the first invention, the adjustment mechanism makes it possible to adjust the bending direction of the curved pipe that supplies water to the discharge pipe. Therefore, by utilizing the property that the flow velocity increases (flow rate increases) in the outer circumference of the curved pipe and decreases (flow rate decreases) in the inner circumference, the discharge flow rate distributed to the two branch pipe sections can be easily adjusted by adjusting the bending direction of the curved pipe.

[0007] The second invention of the present invention is a faucet device in which, in the first invention described above, the adjustment mechanism has a locking mechanism that can lock the bending pipe portion to a position that has been adjusted for movement in the bending direction.

[0008] According to the second invention, the curved pipe section can be locked in a position adjusted for the direction of the curve. Therefore, fluctuations in the water flow rate distributed to the two branched pipe sections can be suppressed.

[0009] The third invention of the present invention is a faucet device in which, in the first or second invention described above, the adjustment mechanism comprises a connection structure that allows for adjustment of the connection position around the pipe axis between the connected pipe portion and the connecting pipe portion of the water supply pipe.

[0010] According to the third invention, the adjustment mechanism can be rationally formed by utilizing a structure in which the connected portion of the water supply pipe is connected to the connecting portion of the water discharge pipe.

[0011] The fourth invention of the present invention is a faucet device in which, in the second invention described above, the adjustment mechanism consists of a connection structure in which the connection between the connected pipe portion and the connecting pipe portion of the water supply pipe is a serrated fit that allows for the selection of the fitting positions of each other, and the locking mechanism is configured to lock the movement of the curved pipe portion in the bending direction by the serrated fit connection structure.

[0012] According to the fourth invention, by configuring the connection pipe portion of the water discharge pipe and the connected pipe portion of the water supply pipe to be connected to each other by serration fitting, the adjustment mechanism and the locking mechanism can be formed rationally and simply.

[0013] The fifth invention of the present invention is a faucet device in which, in the first or second invention described above, the connecting pipe portion of the water discharge pipe is passed through and fixed to the construction wall from the front side of the wall, and is connected to the connected pipe portion of the water supply pipe on the back side of the construction wall.

[0014] According to the fifth invention, the flow rate of water discharged to the two branch pipe sections can be appropriately adjusted by adjusting the bending direction of the bent pipe section on the back side of the wall without disturbing the installation state of the discharge pipe relative to the construction wall.

[0015] The sixth invention of the present invention is a faucet device in which, in the first or second invention described above, the discharge pipe is configured such that the discharge and shut-off of water can be switched by switching the opening and closing of a solenoid valve.

[0016] According to the sixth invention, when the solenoid valve opens, a predetermined constant flow rate of water can always be supplied to the discharge pipe. Therefore, the flow rate of water distributed to the two branch pipe sections can be made less likely to be disrupted.

[0017] The seventh invention of the present invention is a faucet device in which, in the first or second invention described above, the water discharge pipe is made of a transparent material that allows the inside of the pipe to be seen from the outside.

[0018] According to the seventh aspect of the present invention, a water flow in which the discharge flow rates passing through the two branch pipe portions are appropriately adjusted can be visually recognized from the outside. Thereby, the appearance of the water discharge pipe can be improved.

[0019] An eighth aspect of the present invention is the faucet device according to the above-described first or second aspect, wherein the two branch pipe portions branch in directions opposite to each other.

[0020] According to the eighth aspect of the present invention, even when the two branch pipe portions are branched in directions opposite to each other, the adjustment mechanism that enables adjustment of the bending direction of the bent pipe portion around the pipe axis of the connecting pipe portion can appropriately adjust the discharge flow distributed to these branch pipe portions. Therefore, it becomes possible to branch the two branch pipe portions into a shape extending in a wide width in directions opposite to each other. Additionally, the degree of freedom in setting the position of each water discharge port provided in each branch pipe portion can also be increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Hereinafter, modes for carrying out the present invention will be described with reference to the drawings.

[0023] <<First Embodiment>> (Schematic configuration of faucet device 1) First, the configuration of the faucet device 1 according to the first embodiment of the present invention will be described using Figures 1 to 6. In the following description, when directions such as front, back, up, down, left, and right are indicated, they refer to the respective directions shown in each figure. The directions shown in each figure are as seen from the perspective of a user standing in front of the faucet device 1. In the following description, if a specific reference figure is not shown, or if there is no corresponding reference numeral in a reference figure, one of Figures 1 to 6 will be referred to as appropriate.

[0024] As shown in Figure 1, the faucet device 1 according to this embodiment is configured as a wall-mounted faucet installed on the construction wall W of a hand-washing counter. This faucet device 1 has a water discharge pipe 2 attached to the front side (front side of the wall) of the construction wall W, and a water supply pipe 3 connected to the water discharge pipe 2 at the back side (back side of the wall) of the construction wall W.

[0025] The faucet device 1 is configured to receive water from a water pipe (not shown) connected to the water supply pipe 3 and discharge water from the discharge pipe 2. Specifically, the faucet device 1 is configured to switch between discharge and shut-off (discharge / shut-off) by switching the opening and closing of a solenoid valve 4 installed in the water pipe (not shown).

[0026] The solenoid valve 4 is switched on and off by the user waving their hand over an unillustrated hand-wave sensor installed on the front side of the construction wall W. Specifically, the solenoid valve 4 is switched alternately between open and closed each time the user waves their hand over the unillustrated hand-wave sensor. When the solenoid valve 4 is switched to the open state, a preset constant flow rate of water is supplied from the water pipe to the discharge pipe 2.

[0027] The discharge pipe 2 has a connecting pipe section 2A that is passed through and fixed from the front side into a mounting hole W1 in the construction wall W, and branch pipe sections 2B and 2C that branch out to the left and right in a bifurcated manner from the downstream end of the connecting pipe section 2A. Each branch pipe section 2B and 2C is bent in a semi-circular arc shape from the end where it branches out to the left and right so that it forms a circular shape when viewed from above.

[0028] Each branch pipe section 2B and 2C has a semi-circular curved end with a slit-like outlet B1 and C1 that penetrates along the inner surface of the curve. Each branch pipe section 2B and 2C discharges water from the water supply pipe 3 through the connecting pipe section 2A simultaneously from its respective outlet B1 and C1.

[0029] As a result, the water discharged from each spout B1 and C1 flows downward through the circles drawn by each branch pipe section 2B and 2C. Users washing their hands can place their hands below the circles drawn by these branch pipe sections 2B and 2C, allowing the water to flow down onto their hands.

[0030] The water outlet pipe 2 is made of transparent glass material, allowing the user to see inside the pipe from the outside. As a result, the water outlet pipe 2 allows the user to enjoy visually observing the flow of water through each branch pipe section 2B and 2C while washing their hands.

[0031] Each water outlet pipe 2 is handcrafted, resulting in a unique, one-of-a-kind construction. Consequently, variations in size and shape are likely to occur within each water outlet pipe 2. Furthermore, the branch pipe sections 2B and 2C of the water outlet pipe 2 have asymmetrical pipe shapes. Therefore, it is difficult for the water outlet pipe 2 to evenly distribute the water supplied from the water supply pipe 3 to each branch pipe section 2B and 2C.

[0032] Therefore, the faucet device 1 is provided with an adjustment mechanism M that can adjust the water flow rate distributed to each branch pipe section 2B, 2C. As shown in Figures 2 to 3, the adjustment mechanism M is configured to allow adjustment of the connection direction of the water supply pipe 3, which has an arc-shaped curved pipe section 3E, to the connecting pipe section 2A, around the center line C (pipe axis) of the connecting pipe section 2A.

[0033] The adjustment mechanism M adjusts the water flow from the water supply pipe 3 to the discharge pipe 2 by adjusting the connection direction of the water supply pipe 3, thereby adjusting the discharge flow rate distributed to each branch pipe section 2B and 2C. In other words, it utilizes the property that the flow velocity increases (flow rate increases) in the outer circumference of the bend in the curved pipe section 3E and decreases (flow rate decreases) in the inner circumference to adjust the discharge flow rate distributed to each branch pipe section 2B and 2C.

[0034] Furthermore, the adjustment mechanism M includes a locking mechanism M1 that can lock the connection direction of the water supply pipe 3 after the adjustment. This locking mechanism M1 allows the connection direction of the water supply pipe 3 to be locked to the desired adjusted position, thereby suppressing fluctuations in the water discharge flow rate distributed to each branch pipe section 2B, 2C.

[0035] (Composition of each part) The specific configuration of the adjustment mechanism M will be described in detail below, along with the connection structure between the discharge pipe 2 and the water supply pipe 3. First, the configuration of the connecting pipe section 2A of the discharge pipe 2 will be described. As shown in Figure 4, the connecting pipe section 2A is shaped like a straight circular pipe extending from the front side to the back side, and has a connection port A1 at its far end that opens in the direction of the pipe axis.

[0036] As shown in Figure 2, a flange A2 is formed in the middle of the connecting pipe section 2A in the axial direction of the pipe, protruding in a ring-shaped plate in the radial direction of the pipe. The connecting pipe section 2A is attached to the construction wall W as follows: First, the connecting pipe section 2A is passed through the circular mounting hole W1 formed in the construction wall W from the front side, and the flange A2 is set to rest against the front side of the construction wall W.

[0037] Next, the fastening nut N1 is tightened from the rear side onto the male thread A3 formed on the outer circumference of the tip portion of the connecting pipe section 2A that extends beyond the construction wall W to the rear side (behind the wall), thereby fastening it to the construction wall W. As a result, the connecting pipe section 2A is sandwiched between the flange A2 and the fastening nut N1, and is integrally fixed to the construction wall W.

[0038] As shown in Figures 3 and 4, the water supply pipe 3 has a connected pipe section 3D that is inserted into a connection port A1 of a connecting pipe section 2A fixed to the construction wall W and connected to the flow path. The water supply pipe 3 also has a curved pipe section 3E that extends from the connected pipe section 3D toward the back in the figure, bending in a direction that intersects with the pipe axis direction of the connecting pipe section 2A (the direction in which the center line C extends).

[0039] As shown in Figure 4, the tip portion of the pipe section 3D that is inserted into the connection port A1 has a serrated shaft D2 with fine sawtooth-like notches on its outer surface. In addition, a serrated hole A4 with sawtooth-like notches that can be fitted into the serrated shaft D2 in the axial direction of the pipe is formed inside the pipe section 2A facing the connection port A1. Here, the fitting structure between the serrated shaft D2 and the serrated hole A4 corresponds to the "connection structure" of the present invention.

[0040] The serrated shaft D2 is inserted into the serrated hole A4, thereby locking the rotational movement of the connection port A1 around the center line C (around the pipe axis) relative to the serrated hole A4 (see Figure 5). The serrated shaft D2 can be fitted into the serrated hole A4 from any direction around the center line C (around the pipe axis) as long as the protrusions and recesses of the saw teeth of the serrated shaft are in a position to engage with each other.

[0041] Specifically, the serration axis D2 is designed so that its connection direction to the serration hole A4 can be changed around the center line C (around the pipe axis) by an angle corresponding to the pitch between adjacent saw teeth. By adjusting the connection direction as described above, the direction in which the bend of the curved section 3E of the water supply pipe 3 can be adjusted, as shown in Figure 6.

[0042] As shown in Figures 4 and 6, a flange D1 is formed at the base end of the serration axis D2 of the water supply pipe 3, protruding in a ring-like plate shape in the radial direction of the pipe. The flange D1 functions as a regulating seat that abuts against the tip surface of the connecting pipe section 2A with an O-ring P acting as a sealing material in between, when the serration axis D2 of the water supply pipe 3 is inserted into the serration hole A4 of the connecting pipe section 2A.

[0043] The pipe section 3D is connected by being inserted into the connection port A1 of the connecting pipe section 2A as follows: First, the O-ring P is passed through the pipe section 3D from the tip side (front side in the illustration), and the serrated shaft D2 is inserted into the serrated hole A4 of the connecting pipe section 2A. Then, by inserting it as described above, the flange D1 is set to abut against the tip surface of the connecting pipe section 2A with the O-ring P in between.

[0044] Next, the connecting nut N2, which was passed through the water supply pipe 3 from its rear end, is tightened onto the male thread A3 of the connecting pipe section 2A. As a result, the flange-shaped locking seat Na protruding from the inner circumference of the rear end of the connecting nut N2 is pressed against the flange D1 of the water supply pipe 3 from the rear side as shown. Consequently, the flange D1 of the water supply pipe 3 is fixed in place with the O-ring P in between pressed against the end surface of the connecting pipe section 2A.

[0045] Following the above procedure, the connection of the connected pipe section 3D of the water supply pipe 3 is completed. The connected pipe section 3D of the water supply pipe 3 can be easily removed from the connecting pipe section 2A by following the reverse procedure described above.

[0046] Thus, the faucet device 1 is configured with an adjustment mechanism M for adjusting the bending direction of the water supply pipe 3 and a locking mechanism M1 for locking the rotation of the water supply pipe 3, by fitting the serrated shaft D2 of the water supply pipe 3 into the serrated hole A4 of the water discharge pipe 2. Next, a method for adjusting the water discharge flow rate distributed to each branch pipe section 2B, 2C by the adjustment mechanism M will be described.

[0047] As shown in Figure 6, for example, if the water flow rate distributed from the water supply pipe 3 to each branch pipe section 2B and 2C is greater for branch pipe section 2B on the left side of the diagram, the direction of the bend in the bent section 3E of the water supply pipe 3 is adjusted to the left according to the difference in flow rates. As a result, the outer circumference of the bent section 3E of the water supply pipe 3 is adjusted to be to the right of the inner circumference. Consequently, the flow rate distributed to branch pipe section 2C on the right side of the diagram is increased.

[0048] Conversely, if the flow rate distributed to the branch pipe section 2C on the right side of the diagram is greater, the direction of the bend in the bent section 3E of the water supply pipe 3 is adjusted to the right according to the flow rate difference. This adjusts the outer circumference of the bent section 3E of the water supply pipe 3 to the left of the inner circumference. As a result, the flow rate distributed to the branch pipe section 2B on the left side of the diagram is increased. Through this simple operation, the discharge flow rate distributed to each branch pipe section 2B and 2C can be appropriately adjusted.

[0049] In summary, the faucet device 1 according to the first embodiment has the following configuration. The reference numerals in parentheses below correspond to the respective components shown in the above embodiment.

[0050] In other words, the faucet device (1) includes a discharge pipe (2) which includes a connecting pipe section (2A) with a connection port (A1) opening in the direction of the pipe axis, and two branching pipe sections (2B, 2C) which branch off from the connecting pipe section (2A) in a direction intersecting the direction of the pipe axis and discharge water simultaneously from their respective discharge ports (B1, C1), and a water supply pipe (3) which is flow-connected to the connecting pipe section (2A) so as to be able to supply water. The water supply pipe (3) has a connected pipe section (3D) which is flow-connected to the connecting pipe section (2A) in the direction of the pipe axis, and a bent pipe section (3E) which bends from the connected pipe section (3D) in a direction intersecting the direction of the pipe axis. The faucet device (1) further includes an adjustment mechanism (M) which can adjust the direction of bending of the bent pipe section (3E) of the water supply pipe (3) relative to the connecting pipe section (2A) around the pipe axis (C) of the connecting pipe section (2A).

[0051] With the above configuration, the adjustment mechanism (M) makes it possible to adjust the bending direction of the curved pipe section (3E) that supplies water to the discharge pipe (2). Therefore, by utilizing the property that the flow velocity increases (flow rate increases) in the outer circumference of the curved pipe section (3E) and decreases (flow rate decreases) in the inner circumference, the discharge flow rate distributed to the two branch pipe sections (2B, 2C) can be easily adjusted by adjusting the bending direction of the curved pipe section (3E).

[0052] Furthermore, the adjustment mechanism (M) has a locking mechanism (M1) that can lock the curved pipe section (3E) to a position adjusted for its movement in the bending direction. With the above configuration, the curved pipe section (3E) can be locked to a position adjusted for its bending direction. Therefore, fluctuations in the discharge flow rate distributed to the two branch pipe sections (2B, 2C) can be suppressed.

[0053] Furthermore, the adjustment mechanism (M) consists of a connection structure (A4, D2) that allows for adjustment of the connection position around the pipe axis (C) between the connected pipe section (3D) and the connecting pipe section (2A) of the water supply pipe (3). With the above configuration, the adjustment mechanism (M) can be rationally formed by utilizing the structure that connects the connected pipe section (3D) of the water supply pipe (3) to the connecting pipe section (2A) of the discharge pipe (2).

[0054] Furthermore, the adjustment mechanism (M) consists of a connection structure (A4, D2) that uses a serrated fitting to connect the connected pipe section (3D) and the connecting pipe section (2A) of the water supply pipe (3), allowing for the selection of their respective fitting positions. The above serrated fitting connection structure (A4, D2) constitutes a locking mechanism (M1) that locks the movement of the curved pipe section (3E) in the bending direction. In this way, by connecting the connecting pipe section (2A) of the discharge pipe (2) and the connected pipe section (3D) of the water supply pipe (3) to each other using a serrated fitting, the adjustment mechanism (M) and the locking mechanism (M1) can be formed in a rational and simple manner.

[0055] Furthermore, the connecting pipe section (2A) of the discharge pipe (2) is passed through the construction wall (W) from the front side of the wall and fixed, and is connected to the connected pipe section (3D) of the water supply pipe (3) on the back side of the construction wall (W). With the above configuration, the bending direction of the bent pipe section (3E) on the back side of the wall can be adjusted without disturbing the installation state of the discharge pipe (2) on the construction wall (W), thereby appropriately adjusting the discharge flow rate distributed to the two branch pipe sections (2B, 2C).

[0056] Furthermore, the discharge pipe (2) is configured such that water discharge can be switched on or off by switching the opening and closing of the solenoid valve (4). With this configuration, when the solenoid valve (4) is opened, a predetermined constant flow rate of water can always be supplied to the discharge pipe (2). Therefore, the water discharge flow rate distributed to the two branch pipe sections (2B, 2C) is less likely to be disrupted.

[0057] Furthermore, the discharge pipe (2) is made of a transparent material that allows the inside of the pipe to be seen from the outside. With the above configuration, the water flow rate that flows through the two branch pipe sections (2B, 2C) can be appropriately adjusted and the water flow can be seen from the outside. This improves the appearance of the discharge pipe (2).

[0058] Furthermore, the two branch pipe sections (2B, 2C) branch in opposite directions. With the above configuration, even if the two branch pipe sections (2B, 2C) branch in opposite directions, the adjustment mechanism (M) that allows the bending direction of the bent pipe section (3E) to be adjusted around the pipe axis (C) of the connecting pipe section (2A) allows for appropriate adjustment of the discharge flow rate distributed to them. Therefore, it is possible to branch the two branch pipe sections (2B, 2C) in a way that they extend broadly in opposite directions. In addition, the degree of freedom in setting the position of the individual discharge outlets (B1, C1) can be increased.

[0059] Regarding other embodiments: Although an embodiment of the present invention has been described above using one embodiment, the present invention can be implemented in various forms as shown below, in addition to the above embodiment.

[0060] 1. The faucet device of the present invention may be configured as a wall-mounted type or a deck-mounted type. Furthermore, the faucet device may be configured such that a shut-off valve, such as a solenoid valve, is provided upstream of the branching point of each branch pipe section, and the shut-off valve may be provided interposed between the discharge pipe, the water supply pipe, or their connecting ends.

[0061] 2. The bent sections of the water supply pipe may have an arc-shaped curve or an L-shaped bend. The water supply pipe may receive water from a water pipe connected upstream, or it may receive hot water or a mixture of hot and cold water.

[0062] 3. The discharge pipe may have three or more branched sections. The branch shape of each section is not limited to a specific shape and can be various shapes. The transparent material that allows the inside of the discharge pipe to be seen from the outside may be something other than glass, such as acrylic or PVC. The discharge pipe may also be made of a semi-transparent material that allows the inside of the pipe to be partially seen from the outside.

[0063] 4. The adjustment mechanism for adjusting the bending direction of the bent section of the water supply pipe may be formed between the bent section of the water supply pipe and the connected section. That is, an axial connection structure may be provided between the bent section of the water supply pipe and the connected section, allowing the bent section to rotate relative to the connected section in a swivel manner, thereby enabling adjustment of the bending direction of the bent section relative to the connected section. The connection between the connecting section of the discharge pipe and the connecting section of the water supply pipe may be such that one is inserted into the other.

[0064] 5. The locking mechanism for locking the bending direction of the curved pipe section may be a serrated connection that allows for selection of the fitting positions of the movable side member, which is integral with the curved pipe section, and the fixed side member, which is integral with the connecting pipe section, or it may be an axial connection that exerts a rotation-stopping force (locking force) through the sliding frictional resistance between them. Alternatively, instead of a serrated connection, a spline connection may be used, or a key formed on one of the connected pipes may be fitted into a key groove evenly spaced at one or more locations in the circumferential direction of the other pipe to lock it.

[0065] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the description of the embodiments above, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
