Description

The present invention relates to a water faucet device.

Some faucet devices installed around a sink have a water outlet pipe that is rotatably attached to the faucet body. In order to prevent water from being discharged outside the sink, such faucet devices may use a restricting means for restricting the rotation range of the water outlet pipe. For example, a technology has been disclosed that uses a stopper shaft protruding from the base end of the water outlet pipe and a stopper bolt protruding from the tip of the faucet body to which the base end of the water outlet pipe is attached as the restricting means. The faucet device restricts the rotation of the water outlet pipe by abutting the stopper shaft with the stopper bolt. The faucet body can change the restricted range of rotation of the water outlet pipe by adjusting the protruding length of the stopper bolt to arbitrarily select whether or not the stopper shaft and the stopper bolt abut.

(Faucet body)
The faucet body 10 extends in the vertical direction with the base end 10a facing downward. The axial direction of the faucet body 10 is along the vertical direction. Hereinafter, the axial direction of the faucet body 10 may be simply referred to as the "axial direction", the circumferential direction of the faucet body 10 may be simply referred to as the "circumferential direction", and the radial direction of the faucet body 10 may be simply referred to as the "radial direction".
A flange portion 11 is provided at the lower end of the faucet body 10, which extends radially outward from the outer surface of the faucet body 10. The flange portion 11 closes the mounting hole 3a of the counter 3 from above. The faucet body 10 is fixed to the outer periphery of the mounting hole 3a via the flange portion 11.

The faucet body 10 includes a first flow path P1 connected to the water supply unit 4, a second flow path P2 connected to the cartridge 5 and communicating with the first flow path P1, and a third flow path P3 connected to the cartridge 5 separately from the second flow path P2. The first flow path P1 extends in the axial direction. The first flow path P1 is a flow path through which raw water W1 is introduced from the water supply unit 4. The second flow path P2 extends in the axial direction. The second flow path P2 is a flow path through which the raw water W1 introduced into the first flow path P1 is introduced into the cartridge 5. The third flow path P3 extends in the axial direction and penetrates the faucet body 10 in the axial direction. The third flow path P3 is connected to the discharge pipe 20.

A water volume adjustment section P4 is provided inside the faucet body 10 between the upper end of the first flow path P1 and the upper end of the second flow path P2. The water volume adjustment section P4 is a flow path that connects the first flow path P2 and the second flow path P2. The water volume adjustment section P4 opens to the radial outside of the faucet body 10. A handle 12 is connected to the opening of the water volume adjustment section P4 from the radial outside. The handle 12 can be operated from the outside. The faucet device 1 can adjust the amount of purified water W2 discharged from the water outlet pipe 20 by operating the handle 12.
An attachment portion 30 is provided at the tip 10b of the faucet body 10.

(Mounting part)
FIG. 2 is a plan view of the mounting portion 30 as viewed from above.
As shown in Figures 1 and 2, the mounting portion 30 is formed in a cylindrical shape with a bottom. The mounting portion 30 is provided at the tip 10b of the faucet body 10 with the bottom 31 facing downward. The mounting portion 30 constitutes a part of the faucet body 10. A communication hole 31b is provided at the bottom 31 of the mounting portion 30. The communication hole 31b includes a center point 31a of the bottom 31 inside. The communication hole 31b is formed in an elongated hole shape in top view extending radially outward from the center point 31a. The communication hole 31b axially penetrates the bottom 31 at a radially outer end 31b1 and communicates with the third flow path P3.

The bottom 31 is provided with an attachment recess 32 including a communication hole 31b therein. The attachment recess 32 opens upward. The attachment recess 32 has a recess body 32a and a fitting recess 32b. The recess body 32a includes a communication hole 31b therein. The recess body 32a is formed in a perfect circle shape centered on the center point 31a of the bottom 31 when viewed from above. The fitting recess 32b is provided so as to protrude radially outward from the outer periphery of the recess body 32a. Two fitting recesses 32b are provided. The two fitting recesses 32b are provided along the circumferential direction.

A first opening 33 is provided in the bottom 31, radially outward of the radially inner end 31b2 of the communication hole 31b, inside the recess body 32a. The first opening 33 is formed in an arc shape along the circumferential direction. The first opening 33 opens upward. The first opening 33 is formed in a symmetrical shape with respect to a straight line that passes through the circumferential midpoint of the two fitting recesses 32b and extends in the radial direction.
The restricting member 40 is attached from above inside the mounting portion 30. The restricting member 40 is supported by the mounting portion 30.

(Regulation member)
FIG. 3 is a plan view of the restricting member 40 as viewed from above.
FIG. 4 is a plan view of the restricting member 40 attached to the attachment portion 30 as viewed from above.
1, 3 and 4, the restricting member 40 is formed in a disk shape. The diameter of the restricting member 40 is slightly smaller than the inner diameter of the recess body 32a of the mounting recess 32 of the mounting part 30. The restricting member 40 is attached to the mounting part 30 by being fitted into the recess body 32a of the mounting recess 32.

The restricting member 40 is provided with a communication hole 40b. The communication hole 40b is formed in a perfect circle shape centered on the center point 40a of the restricting member 40 when viewed from above. The communication hole 40b penetrates the restricting member 40 in the axial direction. The communication hole 40b overlaps with the radially inner end portion 31b2 of the communication hole 31b. The communication hole 40b communicates with the third flow path P3 via the communication hole 31b.

The restricting member 40 has two mating protrusions 41 that correspond to the mating recesses 32b of the mounting portion 30. The two mating protrusions 41 are provided along the circumferential direction. The mating protrusions 41 protrude radially outward from the side surface 40c of the restricting member 40. The mating protrusions 41 are provided so that they can be mated with the mating recesses 32b. The mating protrusions 41 are mated with the mating recesses 32b to hold the restricting member 40 in a fixed orientation relative to the mounting portion 30. In other words, the mating protrusions 41 and the mating recesses 32b form a holding mechanism 50.

The restricting member 40 can be removed from the mounting portion 30 by releasing the engagement between the engaging protrusion 41 and the engaging recess 32b. In other words, the restricting member 40 is detachably provided on the mounting portion 30.

The restricting member 40 can be fitted (attached) to the fitting protrusion 41 and the fitting recess 32b in a state where it is turned over (flipped) with respect to the bottom 31 of the attachment portion 30. At this time, the restricting member 40 is attached to the upper surface of the bottom 31 by being turned over around a reversal line Lr that extends in the radial direction of the restricting member 40. The reversal line Lr is a straight line that passes through the circumferential midpoint of the two fitting protrusions 41.

The restricting member 40 is provided with a second opening 42 that penetrates the restricting member 40 in the axial direction. The second opening 42 is provided radially outward from the communication hole 40b. The second opening 42 extends along the circumferential direction. The second opening 42 is formed in an arc shape on the same pitch circle as the first opening 33. The formation range of the second opening 42 is equal to the formation range of the first opening 33. A part of the second opening 42 overlaps with a part of the first opening 33 in the vertical direction when the restricting member 40 is attached to the attachment portion 30. The first opening 33 and the second opening 42 overlap in the vertical direction to form a restricting groove 60 that communicates in the vertical direction and opens upward. The formation range of the restricting groove 60 coincides with the overlapping range of the first opening 33 and the second opening 42. In the example of FIG. 4, the formation range of the restricting groove 60 coincides with the formation range of the part of the first opening 33 that overlaps with the second opening 42. The restricting groove 60 extends along the circumferential direction.

FIG. 5 is a plan view of the restricting member attached upside down to the attachment portion according to the first embodiment, as viewed from above.
4 and 5, the second opening 42 is provided asymmetrically with respect to the reversal line Lr. Therefore, when the regulating member 40 is attached to the bottom 31 of the mounting portion 30 with the regulating member 40 turned over with respect to the bottom 31, the formation range of the second opening 42 as viewed from above is reversed before and after the regulating member 40 is turned over. When the formation range of the second opening 42 is reversed, the overlapping range of the first opening 33 and the second opening 42 is reversed. Therefore, the formation range of the regulating groove 60 is reversed before and after the regulating member 40 is turned over.

When the range in which the restricting groove 60 is formed is to coincide with the range in which the first opening 33 is formed, the restricting member 40 may be removed. In this case, the restricting groove 60 is formed only by the first opening 33.
Depending on the situation, the user of the faucet device 1 can choose to either turn the regulating member 40 over or remove the regulating member 40 .

(Retention mechanism)
The holding mechanism 50 includes the above-mentioned fitting recess 32b and fitting protrusion 41. The holding mechanism 50 holds the regulating member 40 in a fixed orientation relative to the mounting portion 30 by fitting the fitting recess 32b and the fitting protrusion 41. In addition, the holding mechanism 50 can change the orientation of the regulating member 40 relative to the mounting portion 30. In this embodiment, the holding mechanism 50 can invert the regulating member 40 from the mounting portion 30. In this embodiment, the "orientation of the regulating member" that the holding mechanism 50 holds and can change is the "front and back of the regulating member." Depending on the user's situation, the faucet device 1 can be used even without attaching the regulating member 40.

(Outlet pipe)
As shown in FIG. 1, a discharge pipe 20 is provided on the upper side of the faucet body 10 across the restricting member 40. The discharge pipe 20 is formed to protrude upward from the restricting member 40 along the axial direction of the faucet body 10. The base end 20a of the discharge pipe 20 is supported by the faucet body 10 so as to be rotatable in the circumferential direction. The discharge pipe 20 communicates with the third flow path P3 of the faucet body 10 via the communication holes 31b, 40b. The discharge pipe 20 has a connection part 21 connected to the mounting part 30 of the faucet body 10, a discharge pipe main body 22 that is inserted into the connection part 21 and extends upward from the connection part 21, and a discharge port 23 provided at the end of the discharge pipe main body 22 on the opposite side to the connection part 21. The connection part 21, the discharge pipe main body 22, and the discharge port 23 are integrated.

FIG. 6 is a cross-sectional view taken along the vertical direction at the connection portion 21 of the discharge pipe 20. As shown in FIG.
FIG. 7 is a plan view of the connection portion 21 of the discharge pipe 20 as viewed from below.
The connection part 21 is provided at the base end 20a of the water discharge pipe 20. As shown in Figs. 6 and 7, the connection part 21 is formed in a cylindrical shape extending in the axial direction. The outer shape of the connection part 21 is formed in a multi-step shape in a side view. The connection part 21 communicates with the communication holes 31b, 40b. A protrusion 24 is provided at the lower end 21a of the connection part 21. The protrusion 24 protrudes downward from the lower end 21a of the connection part 21. The protrusion 24 is accommodated in the restricting groove 60 from above. The protrusion 24 is movable along the circumferential direction within the restricting groove 60. The movement range of the protrusion 24 is restricted by the restricting groove 60. In other words, the water discharge pipe 20 having the protrusion 24 is restricted from rotating in the circumferential direction by the restricting groove 60. Therefore, the rotation trajectory of the water discharge pipe 20 is determined by the formation range of the restricting groove 60. Therefore, the faucet device 1 can reverse the restricted range of circumferential rotation of the discharge pipe 20 by turning the restricting member 40 upside down and attaching it to the mounting portion 30. Also, the faucet device 1 can change the restricted range of circumferential rotation of the discharge pipe 20 by turning the restricting member 40 upside down or removing it.

As shown in Fig. 1, the discharge pipe body 22 is a cylindrical member inserted between the connection part 21 and the mounting part 30 of the faucet body 10. The discharge pipe body 22 stands upward from the tip 10b of the faucet body 10. The discharge pipe body 22 is bent into an inverted U-shape just before the tip 20b of the discharge pipe 20. The discharge pipe body 22 communicates with the connection part 21.
The water outlet 23 is provided at the tip 20b of the water outlet pipe 20. The water outlet 23 is connected to the connection part 21 and the water outlet pipe body 22. The water outlet 23 opens downward toward the sink. The water outlet 23 discharges the purified water W2 introduced into the water outlet pipe 20 from the third flow path P3 into the sink.

Next, the functions of the mounting portion 30 and the restricting member 40 will be described.
4 and 5, when the restricting member 40 is attached to the attachment portion 30, the first opening 33 and the second opening 42 overlap to form a restricting groove 60. In the example of Fig. 4, the left end of the restricting groove 60 coincides with the left end of the first opening 33, and the right end of the restricting groove 60 coincides with the right end of the second opening 42. The restricting groove 60 is formed so that the area on the left side of the reversal line Lr is wider.

Here, by inverting the regulating member 40 around the reversal line Lr with respect to the mounting portion 30 from the example in FIG. 4, the formation range of the second opening 42 is inverted, and the example in FIG. 5 is shown. In the example in FIG. 5, the left end of the regulating groove 60 coincides with the left end of the second opening 42, and the right end of the regulating groove 60 coincides with the right end of the first opening 33. The regulating groove 60 is formed with a wider area on the right side of the reversal line Lr. That is, the formation range of the regulating groove 60 is inverted between the example in FIG. 4 and the example in FIG. 5.

In this way, in the above-mentioned faucet device 1, the formation range of the restriction groove 60 can be reversed by inverting the restriction member 40 relative to the mounting portion 30. Here, the restriction groove 60 accommodates the protrusion 24 of the discharge pipe 20, so the discharge pipe 20 can only rotate within the range of the restriction groove 60. Therefore, the faucet device 1 can easily adjust the restriction range of the rotation of the discharge pipe 20 relative to the faucet body 10 simply by inverting the restriction member 40 relative to the mounting portion 30.

Furthermore, by removing the restricting member 40, the faucet device 1 can make the formation range of the first opening 33 coincide with the formation range of the restricting groove 60. Therefore, the faucet device 1 can make the formation range of the restricting groove 60 longer in the circumferential direction compared to when the restricting member 40 is used. When the formation range of the restricting groove 60 is longer in the circumferential direction, the movement range of the protrusion 24 of the discharge pipe 20 becomes longer in the circumferential direction. Therefore, the faucet device 1 can make the restriction range of the rotation of the discharge pipe 20 longer in the circumferential direction simply by removing the restricting member 40.

(Action and Effect)
In the faucet device 1 of this embodiment, the attachment portion 30 has a first opening 33. The restricting member 40 has a second opening 42 that overlaps with the first opening 33. The first opening 33 and the second opening 42 overlap to form a restricting groove 60 that restricts the rotation of the discharge pipe 20. The discharge pipe 20 has a protrusion 24 that is inserted into the restricting groove 60.
According to this configuration, with a simple structure that merely requires providing a first opening 33 in the mounting portion 30, a second opening 42 in the regulating member 40, and a protrusion 24 on the discharge pipe 20, the faucet device 1 can regulate the rotation of the discharge pipe 20 relative to the faucet body 10.
In addition, the faucet device 1 is equipped with a holding mechanism 50 that is capable of changing the orientation of the regulating member 40 relative to the mounting portion 30 and holds the regulating member 40 in a constant orientation relative to the mounting portion 30. The range in which the second opening 42 overlaps with the first opening 33 changes when the orientation of the regulating member 40 relative to the mounting portion 30 is changed. Therefore, the faucet device 1 can change the formation range of the regulating groove 60 by changing the orientation of the regulating member 40 relative to the mounting portion 30. Therefore, the faucet device 1 can easily change the regulating range of the rotation of the discharge pipe 20 simply by changing the orientation of the regulating member 40 relative to the mounting portion 30.

In addition, since there is no need to remove the faucet body 10 from the counter 3 to change the restricted range of rotation of the discharge pipe 20, the faucet device 1 can be made easier to work with. Furthermore, since the faucet device 1 does not require the use of any other components than the restricting member 40 to change the restricted range of rotation of the discharge pipe 20, the number of parts can be reduced compared to conventional technology. Furthermore, the faucet device 1 can restrict the rotation of the discharge pipe 20 with a simple configuration that includes the mounting portion 30, the restricting member 40, and the protrusion 24. Therefore, the present invention can be applied even when the diameter of the discharge pipe 20 is relatively small.

In the faucet device 1 of this embodiment, the retaining mechanism 50 has a fitting recess 32 b provided in the mounting portion 30 and a fitting protrusion 41 provided in the regulating member 40 .
According to this configuration, the retention mechanism 50 can retain the restricting member 40 in a fixed orientation relative to the mounting portion 30 by engaging the engaging recess 32b with the engaging protrusion 41. Therefore, the number of parts of the faucet device 1 can be reduced compared to, for example, a case in which the restricting member 40 is fastened to the mounting portion 30 by a screw.

In the faucet device 1 of this embodiment, the retaining mechanism 50 has a plurality of fitting protrusions 41 that fit into a plurality of fitting recesses 32b.
According to this configuration, the holding mechanism 50 can fit the fitting recess 32b and the fitting protrusion 41 at multiple locations. Therefore, the holding mechanism 50 can hold the restricting member 40 on the attachment portion 30 more firmly than when the holding mechanism 50 has one fitting protrusion 41.

In the water faucet device 1 of this embodiment, the restricting member 40 is formed in a disk shape. The restricting member 40 can be attached upside down. The second opening 42 is provided asymmetrically with respect to the reversal line Lr.
According to this configuration, the faucet device 1 can invert the regulating member 40 around the reversal line Lr, thereby inverting the formation range of the second opening 42 as viewed from above before and after inverting the regulating member 40. The range of the second opening 42 that overlaps with the first opening 33 is inverted by inverting the regulating member 40. Therefore, the faucet device 1 can invert the formation range of the regulating groove 60 by inverting the regulating member 40. Therefore, the faucet device 1 can invert the regulating range of rotation of the water discharge pipe 20 simply by inverting the regulating member 40. Therefore, the faucet device 1 can easily change the regulating range of rotation of the water discharge pipe 20.

The faucet device 1 of this embodiment allows a choice between turning the regulating member 40 upside down or removing the regulating member 40.
With this configuration, the user of the faucet device 1 can turn the restricting member 40 over or remove the restricting member 40 as needed. This allows the faucet device 1 to change the range in which the restricting groove 60 is formed by changing the way the restricting member 40 is used. Therefore, the faucet device 1 can easily change the range in which the rotation of the discharge pipe 20 is restricted simply by changing the way the restricting member 40 is used.

In the faucet device 1 of this embodiment, the regulating member 40 is attached inside the mounting portion 30.
According to this configuration, the water faucet device 1 can prevent the restricting member 40 from being exposed to the outside, thereby maintaining the design appeal of the water faucet device 1.

In the faucet device 1 of this embodiment, the formation area of the second opening 42 is equal to the formation area of the first opening 33 .
According to this configuration, the faucet device 1 can prevent the first opening 33 and the second opening 42 from being formed over an unnecessarily wide area in order to form the restriction groove 60. Therefore, the faucet device 1 can ensure the strength of the mounting portion 30 and the restriction member 40.

In the above-described first embodiment, the communication hole 40b is formed in a perfect circular shape centered on the central point 40a of the restricting member 40 when viewed from above, but this is not limited thereto.
FIG. 8 is a plan view of another restricting member 40A as viewed from above.
As shown in FIG. 8, the communication hole 40b may be formed in a long hole shape including a center point 40a in the top view. In this case, the communication hole 40b extends radially from the center point 40a. The entire communication hole 40b penetrates the regulating member 40A in the axial direction. The communication hole 40b opens in correspondence with the communication hole 31b of the mounting portion 30. The communication hole 40b overlaps with the communication hole 31b to form an introduction flow path for the purified water W2 between the faucet body 10 and the discharge pipe 20. Therefore, compared to the case where the communication hole 40b is formed in a perfect circle shape in a top view, the faucet device 1 using the other regulating member 40A can have a wider introduction flow path for the purified water W2. Therefore, this faucet device 1 can increase the flow rate of the purified water W2 introduced from the faucet body 10 to the discharge pipe 20.

The communication hole 40b in the other restricting member 40A may be a recess that opens toward the faucet body 10, as long as the end on the center point 40a side of the communication hole 40b axially penetrates the restricting member 40A. However, if the entire communication hole 40b penetrates the restricting member 40A, the introduction flow path of the purified water W2 can be made wider, and the flow rate of the purified water W2 to the discharge pipe 20 can be increased.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to Figures 9 and 10. Note that, among the configurations of the second embodiment, the same configurations as those of the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted as appropriate.

In the first embodiment, two fitting recesses 32b are provided in the mounting portion 30. In contrast, the second embodiment differs from the first embodiment in that four fitting recesses 32b are provided in the mounting portion 30A.
9, the four fitting recesses 32b are arranged at equal intervals in the circumferential direction. The first opening 33 is formed symmetrically with respect to a line that passes through the circumferential midpoints of the four fitting recesses 32b and extends in the radial direction.

(Regulation member)
The restricting member 40 is attached to the attachment portion 30A so as to be rotatable in the circumferential direction.

FIG. 10 is a plan view of another restricting member 40B as viewed from above.
10, the regulating member 40B and the regulating member 40 differ in the range in which the second opening 42 is formed. The second opening 42 in the regulating member 40B is formed in a symmetrical shape with respect to the reversal line Lr.
A user of the faucet device 1 can select one of the plurality of regulating members 40, 40B depending on the situation and attach it to the faucet body 10. The regulating member 40B is attached to the attachment portion 30A so as to be rotatable in the circumferential direction, like the regulating member 40. That is, in this embodiment, the "orientation of the regulating member" that is held and can be changed by the holding mechanism 50 includes not only the "front and back of the regulating member" but also the "rotational position of the regulating member."

(Retention mechanism)
The holding mechanism 50 holds the regulating member 40 at a fixed rotational position relative to the mounting portion 30A. The holding mechanism 50 has four fitting recesses 32b provided in the mounting portion 30A and two fitting protrusions 41 provided in the regulating member 40. A user of the faucet device 1 selects two fitting recesses 32b that are adjacent to each other in the circumferential direction from the four fitting recesses 32b, and fits them into the two fitting protrusions 41 provided in the regulating member 40.

Next, the function of the mounting portion 30A and the restricting member 40 will be described.
The regulating member 40 can change its rotational position relative to the mounting portion 30A. When a user of the faucet device 1 changes the rotational position of the regulating member 40 relative to the mounting portion 30A, the user first releases the engagement between the engaging recess 32b and the engaging protrusion 41. The user of the faucet device 1 then rotates the regulating member 40 in the circumferential direction, and engages the engaging protrusion 41 with a different engaging recess 32b than before the rotation. Due to the engagement between the engaging recess 32b and the engaging protrusion 41, the regulating member 40 is held constant at the position after rotation. In this manner, the rotational position of the regulating member 40 relative to the mounting portion 30A is changed.

When the rotational position of the regulating member 40 relative to the mounting portion 30A is changed, the overlapping range of the first opening 33 and the second opening 42 is changed. In other words, the formation range of the regulating groove 60 is changed. Therefore, a user of the faucet device 1 can easily change the regulating range of rotation of the discharge pipe 20 by simply rotating the regulating member 40 circumferentially relative to the mounting portion 30A and changing the fitting recess 32b used to fit the fitting protrusion 41.
In addition, the faucet device 1 can change the range in which the regulating groove 60 is formed by changing the regulating member 40 to a different regulating member 40B.

(Action and Effect)
In the faucet device 1 of this embodiment, the restricting member 40 is rotatable circumferentially relative to the mounting portion 30A.
According to this configuration, the faucet device 1 can change the overlapping range between the first opening 33 and the second opening 42 simply by rotating the regulating member 40 circumferentially relative to the faucet body 10. This allows the faucet device 1 to change the formation range of the regulating groove 60. In addition, the holding mechanism 50 can hold the regulating member 40 at a constant rotational position relative to the mounting part 30A after rotating the regulating member 40 relative to the mounting part 30A to change the formation range of the regulating groove 60. This allows the faucet device 1 to finely adjust the formation range of the regulating groove 60. Therefore, the faucet device 1 can finely adjust the restriction range of the rotation of the water discharge pipe 20 and adjust the rotation range of the water discharge pipe 20 to an appropriate range.

In the faucet device 1 of this embodiment, the retention mechanism 50 has four fitting recesses 32 b , which is more than the number of fitting protrusions 41 .
According to this configuration, a user of the faucet device 1 can select two of the four mating recesses 32b to be mated with the mating protrusion 41. This allows the user of the faucet device 1 to easily and precisely change the rotational position of the regulating member 40 relative to the attachment portion 30 simply by selecting the mating recesses 32b to be used for mating with the mating protrusion 41.

In the water faucet device 1 of this embodiment, one of the plurality of restricting members 40, 40B can be selected and attached to the attachment portion 30A. The plurality of restricting members 40, 40B each have a different range in which the second opening 42 is formed.
With this configuration, the user of the faucet device 1 can use the restricting member 40 and the restricting member 40B differently as needed. This allows the faucet device 1 to change the range in which the restricting groove 60 is formed by changing the restricting member 40 and the restricting member 40B. Therefore, the faucet device 1 can easily change the range in which the rotation of the discharge pipe 20 is restricted by simply changing the restricting member 40 and the restricting member 40B.

Third Embodiment
Next, a third embodiment of the present invention will be described with reference to Fig. 11 to Fig. 16. Note that, among the configurations of the third embodiment, the same configurations as those of the above-mentioned embodiments are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.
FIG. 11 is a plan view of the mounting portion 30B as viewed from above.
In each of the above-described embodiments, the fitting recess 32b that fits with the fitting protrusion 41 of the regulating member 40, 40A, 40B is provided in the bottom 31 of the mounting portion 30, 30A. In contrast, the third embodiment differs from the above-described embodiments in that, as shown in FIG. 11 , the fitting recess 34a that fits with the fitting protrusion 41 is provided in the tubular portion 34 of the mounting portion 30B.

(Mounting part)
Unlike the mounting portion 30 of the first embodiment, the bottom 31 of the mounting portion 30B of this embodiment does not have a mounting recess 32, and the upper surface of the bottom 31 is formed flat except for the communication hole 31b and the first opening 33. Nine fitting recesses 34a are provided in the cylindrical portion 34. The nine fitting recesses 34a are arranged at equal intervals in the circumferential direction. Each fitting recess 34a opens upward and penetrates the cylindrical portion 34 in the radial direction.

(Regulation member)
FIG. 12 is a plan view of the restricting member 40C as viewed from above.
FIG. 13 is a plan view of the restricting member 40C attached to the attachment portion 30B as viewed from above.
As shown in Figures 12 and 13, the restricting member 40C is provided with three mating protrusions 41. The three mating protrusions 41 are arranged at equal intervals in the circumferential direction. The reversal line Lr of the restricting member 40C is a straight line that passes through the circumferential midpoint of the three mating protrusions 41 and extends in the radial direction. The second opening 42 is formed symmetrically with respect to the reversal line Lr. The restricting member 40C is attached so as to fit into the inner surface of the tubular portion 34 of the mounting portion 30B. The restricting member 40C is attached to the mounting portion 30 in a state in which it covers the radially outer end 31b1 of the communication hole 31b from above.

(Retention mechanism)
FIG. 14 is a plan view of the restricting member 40C, which is attached to the attachment portion 30B with its rotational position changed, as viewed from above.
13 and 14 , the retention mechanism 50 has nine mating recesses 34a and three mating protrusions 41. A user of the faucet device 1 selects three mating recesses 34a that are adjacent to each other in the circumferential direction from the nine mating recesses 34a, and matingly engages the three mating protrusions 41 with the selected three mating recesses 34a.

(Action and Effect)
In the faucet device 1 of this embodiment, the retention mechanism 50 has more fitting recesses 34a and fitting protrusions 41 than in each of the above-described embodiments.
According to this configuration, the water faucet device 1 can adjust the range in which the restriction groove 60 is formed more finely than in the above-described embodiments. Therefore, the water faucet device 1 can adjust the restriction range of the rotation of the water discharge pipe 20 more finely than in the above-described embodiments.

In the faucet device 1 of this embodiment, a fitting recess 34 a is provided in the tubular portion 34 of the mounting portion 30 .
According to this configuration, the fitting recess 34a and the fitting protrusion 41 can be exposed to the outside of the faucet device 1. This allows a user of the faucet device 1 to visually check the fitting recess 34a and the fitting protrusion 41 without removing the water discharge pipe 20 from the faucet body 10. Therefore, if an abnormality occurs in the fitting recess 34a or the fitting protrusion 41, the user of the faucet device 1 can easily detect the abnormality and perform maintenance. This improves the maintainability of the faucet device 1.

In the faucet device 1 of this embodiment, the regulating member 40C is attached to the mounting portion 30B in a state in which it covers the radially outer end portion 31b1 of the communication hole 31b from above.
With this configuration, the restricting member 40B can receive the water pressure of the purified water W2 introduced into the discharge pipe 20 through the end 31b1 of the communication hole 31b. This allows the faucet device 1 to prevent the water pressure of the purified water W2 from being directly applied to the discharge pipe 20. Therefore, the faucet device 1 can improve the durability of the discharge pipe 20. Furthermore, the faucet device 1 can prevent the discharge pipe 20 from coming off the faucet body 10 due to the water pressure of the purified water W2. This allows the stability of the faucet device 1 to be improved.

In the above third embodiment, the mounting portion 30B and the restricting member 40C are held by fitting together, but the present invention is not limited to this.
FIG. 15 is a plan view of a mounting portion 30C according to a modification of the third embodiment, as viewed from above.
FIG. 16 is a plan view of a restricting member 40D according to a modification of the third embodiment, as viewed from above.
As shown in Fig. 15, the bottom 31 of the mounting portion 30C is provided with a first retaining opening 35 that opens to the water discharge pipe 20 side. A female screw portion is formed on the inner peripheral surface of the first retaining opening 35. The first retaining openings 35 are provided on a straight line extending in the radial direction, and at least one pair is provided at symmetrical positions with respect to the center point 31a of the bottom 31. In this embodiment, a total of three pairs of first retaining openings 35 are provided. That is, a total of six first retaining openings 35 are provided. The number of first retaining openings 35 can be changed as appropriate as long as it is two or more.

As shown in FIG. 16, the regulating member 40D is formed with second retaining openings 43 that penetrate the regulating member 40D in the axial direction. Two second retaining openings 43 are formed side by side in the circumferential direction. The two second retaining openings 43 are provided on a straight line extending in the radial direction, at positions symmetrical with respect to the center point 40a of the regulating member 40D. The two second retaining openings 43 are provided so as to be superimposable on any pair of first retaining openings 35 out of the three pairs of first retaining openings 35 provided in the mounting portion 30C. The number of second retaining openings 43 can be changed as appropriate.

In this modified example, the retaining mechanism 50 is composed of a first retaining opening 35, a second retaining opening 43, and a screw (not shown) that is fastened to the first retaining opening 35 while inserted into the first retaining opening 35 and the second retaining opening 43.
According to this configuration, the faucet device 1 can easily and firmly hold the restricting member 40D to the mounting portion 30C simply by inserting and fastening a screw into the overlapping first retaining opening 35 and second retaining opening 43. This improves the workability of the faucet device 1 and the strength of the faucet device 1.

The faucet device 1 can change the overlap range between the first opening 33 and the second opening 42 by changing the first retaining opening 35 to which the screw is fastened. This allows the faucet device 1 to easily change the formation range of the restriction groove 60 that restricts the movement range of the protrusion 24.

Fourth Embodiment
Next, a fourth embodiment of the present invention will be described with reference to Fig. 17. Note that, among the configurations of the third embodiment, the same configurations as those of the above-mentioned embodiments will be denoted by the same reference numerals, and the description thereof will be omitted as appropriate.
FIG. 17 is an exploded perspective view of the periphery of the restricting member 40E.
As shown in FIG. 17 , the upper surface 10 c of the faucet body 10 is provided with an outer peripheral wall 13 that protrudes upward, a protrusion 14 that protrudes upward, and a communication hole 15 .
The outer surface of the outer peripheral wall 13 is formed to be flush with the outer surface of the faucet body 10. The protrusions 14 are provided along the circumferential direction. The communication hole 15 includes the center point of the upper surface 10c therein. The communication hole 15 is formed in an elongated hole shape when viewed from above, extending radially outward from the center point of the upper surface 10c. The communication hole 15 axially penetrates the upper surface 10c at the radially outer end 15b, and communicates with the third flow path P3.

The mounting portion 30D is provided on the base end 20a side of the discharge pipe 20, i.e., on the lower end 21a of the connection portion 21 of the discharge pipe 20. The mounting portion 30D is formed in a cylindrical shape with a larger diameter than the connection portion 21. The mounting portion 30D is in communication with the discharge pipe 20 in the vertical direction. The underside of the mounting portion 30D is provided with a first opening 33 that opens toward the faucet body 10, and six first retaining openings 35. The first openings 33 are formed to be longer in the circumferential direction than the protrusions 14.

The restricting member 40E is attached to the lower surface of the mounting portion 30D. The restricting member 40E is formed in a disk shape with the plate thickness direction coinciding with the up-down direction. The restricting member 40E is inserted into the outer peripheral wall 13 together with the mounting portion 30D in a state where it is attached to the mounting portion 30D. The restricting member 40E is provided with a communication hole 40b penetrating the restricting member 40E in the up-down direction, a second opening 42, and two second holding openings 43.
The second opening 42 is formed to be longer in the circumferential direction than the protrusion 14 .
The communication hole 40b overlaps with a radially inner end portion 15a of the communication hole 15. The communication hole 40b communicates with the third flow passage P3 via the communication hole 15.

The restricting member 40E is held on the mounting portion 30D by fastening the screw B to the first holding opening 35 while the screw B is inserted into the first holding opening 35 and the second holding opening 43. That is, the holding mechanism 50 is composed of the first holding opening 35, the second holding opening 43, and the screw B that is fastened to the first holding opening 35 while the screw B is inserted into the overlapping first holding opening 35 and second holding opening 43. The restricting member 40E is fastened and fixed to the mounting portion 30D, so it is firmly held without falling off the mounting portion 30D.

With the restricting member 40E held by the mounting portion 30D, the protrusion 14 of the faucet body 10 is inserted into the restricting groove 60 formed by overlapping the first opening 33 and the second opening 42. The first opening 33 and the second opening 42 are overlapped so that the restricting groove 60 is longer in the circumferential direction than the protrusion 14. Therefore, when the discharge pipe 20 is rotated in the circumferential direction with the protrusion 14 inserted into the restricting groove 60, the protrusion 14 moves relative to the restricting groove 60. The relative movement of the protrusion 14 is restricted by the restricting groove 60. In other words, the circumferential rotation of the discharge pipe 20 is restricted by the restricting groove 60.
Furthermore, the user of the faucet device 1 can change the overlapping range of the first opening 33 and the second opening 42 by changing the first retaining opening 35 into which the screw B is fastened. This allows the faucet device 1 to easily change the formation range of the restriction groove 60 that restricts the movement range of the protrusion 24. In other words, the faucet device 1 can easily change the range of rotation restriction of the discharge pipe 20.

In the faucet device 1 of this embodiment, the attachment portion 30D has a first opening 33. The restricting member 40E has a second opening 42 that overlaps with the first opening 33. The first opening 33 and the second opening 42 overlap to form a restricting groove 60 that restricts the rotation of the discharge pipe 20. The faucet body 10 has a protrusion 14 that is inserted into the restricting groove 60.
According to this configuration, with a simple structure that merely requires providing a first opening 33 in the mounting portion 30D, a second opening 42 in the regulating member 40E, and a protrusion 24 on the discharge pipe 20, the faucet device 1 can regulate the rotation of the discharge pipe 20 relative to the faucet body 10.
In addition, the water faucet device 1 is provided with a holding mechanism 50 that can change the orientation of the regulating member 40E relative to the mounting portion 30D and holds the regulating member 40E in a fixed orientation relative to the mounting portion 30D. In this embodiment, the "orientation of the regulating member" that the holding mechanism 50 can hold and change includes not only the "front and back of the regulating member" but also the "rotational position of the regulating member". The range of the second opening 42 overlapping with the first opening 33 changes as the orientation of the regulating member 40E relative to the mounting portion 30D is changed. Therefore, the water faucet device 1 can change the formation range of the regulating groove 60 by changing the orientation of the regulating member 40E relative to the mounting portion 30D. Therefore, the water faucet device 1 can easily change the regulating range of the rotation of the water discharge pipe 20 simply by changing the orientation of the regulating member 40E relative to the mounting portion 30D.

In addition, since there is no need to remove the faucet body 10 from the counter 3 to change the restricted range of rotation of the discharge pipe 20, the faucet device 1 can be made easier to work with. Furthermore, since there is no need to use any other members than the restricting member 40E to change the restricted range of rotation of the discharge pipe 20, the number of parts can be reduced compared to conventional technology. Furthermore, the faucet device 1 can restrict the rotation of the discharge pipe 20 with a simple configuration that includes the mounting portion 30D, the restricting member 40E, and the protrusion 14. Therefore, the present invention can be applied even when the diameter of the discharge pipe 20 is relatively small.

In each of the above-described embodiments, the faucet device 1 is described as being installed in an upright position above the counter 3, but this is not limited to the above. The faucet device 1 may also be attached so as to extend laterally or downwardly from an attachment portion other than the counter 3.

In the above-described embodiments, the restricting members 40, 40A, 40B, 40C, 40D, and 40E are formed in a disk shape, but this is not limited thereto. The restricting members 40, 40A, 40B, 40C, 40D, and 40E may be formed in, for example, a ginkgo shape when viewed from above.

In each of the above-described embodiments, the formation range of the second opening 42 is described as being equal to the formation range of the first opening 33, but this is not limited thereto. The formation range of the second opening 42 may be wider or narrower than the formation range of the first opening 33.

In the above-described embodiments, the fitting recesses 32b, 34a are provided on the mounting portions 30, 30A, 30B, and the fitting protrusions 41 are provided on the regulating members 40, 40A, 40B, 40C, but this is not limited to the above. The fitting protrusions may be provided on the mounting portions, and the fitting recesses may be provided on the regulating members. In this case, the protruding direction of the fitting protrusions and the opening direction of the fitting recesses may be changed to match the shapes of the mounting portions and the regulating members.

In each of the above-described embodiments, the case where two or three mating protrusions 41 are provided has been described, but this is not limited thereto. One mating protrusion 41 or four or more mating protrusions 41 may be provided as long as the number is equal to or less than the number of mating recesses 32b, 34a. The number of mating recesses 32b, 34a can also be changed as appropriate.

In addition, the components in the above-described embodiment may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above-described modified examples may be combined as appropriate.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the scope of the appended claims.

The faucet device of the present invention allows the rotational regulation range of the water outlet pipe to be easily changed. The faucet device of the present invention is used, for example, in sinks for general households and commercial sinks.
