As shown in FIG. 1 , the faucet device 1 is a plumbing facility, that is, the counter faucet device 1 of a kitchen includes a faucet device main body 10 . The faucet device main body 10 includes a water discharge section 11 placed on a counter and a water supply piping section 40 arranged in the counter (specifically, arranged in a later-described cabinet section 30 provided in the counter). Prepare.

A kitchen counter is formed with a concave downward sink. The sink has a drain (not shown) formed in the bottom of the sink. The drain port is connected to a drain pipe (not shown) to discharge water supplied to the sink to the drain pipe. The term “water” includes normal temperature water such as city water (tap water), as well as hot water and mixed water.

The water discharger 11 includes a water discharge port 11a, and discharges water from the water discharge port 11a toward the sink. The water discharger 11 is a so-called spout.

The body portion 12 includes a single lever cartridge 12a and an operating lever 12b provided therein. The single lever cartridge 12a adjusts the flow rate and temperature of the water discharged from the water discharger 11 by the user's operation of the control lever 12b. The operating lever 12b is pivotally supported by the body portion 12 so as to be able to swing in the front-rear direction and the left-right direction, for example.

In this case, for example, by rocking the operation lever 12b in the left-right direction, the flow rate of water discharged from the water discharger 11 is adjusted, and by rocking the operation lever 12b in the front-rear direction, the water is discharged from the water discharger 11. The temperature of the water used is adjusted. The mode of adjusting the flow rate and temperature of water in the operation unit 12 is not limited to the operation lever 12b, and any mode that can adjust the flow rate and adjustment of water may be used.

The water faucet device main body 10 described above is connected to a water supply pipe 21 and a hot water supply pipe 22, which will be described later, via a single lever cartridge 12a provided in the main body portion 12. As shown in FIG. The water discharged from the water discharger 11 is clean water (tap water) as described above.

Water from a water supply pipe 21 and water (hot water) from a hot water supply pipe 22 are supplied to the faucet device main body 10 . As described above, in the single lever cartridge 12 a , the water in the water supply pipe 21 and the hot water in the hot water supply pipe 22 are mixed, and the mixed water is discharged from the water discharge port 11 a of the water discharger 11 .

In the faucet device main body 10, the water supply pipe 21 and the hot water supply pipe 22 may be provided with a temporary water stopping function by using electromagnetic valves. Also, a solenoid valve for temporary water stoppage may be provided in the mixing flow path.

It should be noted that the temperature of the water discharged from the water discharging portion 12 may be adjusted by an adjusting means other than the operation lever 12b. The body portion 12 may have at least an operation portion capable of adjusting the flow rate of water discharged from the water discharge portion.

Also, the water discharge section 11 of the faucet device main body 10 is installed on the cabinet section 30 . Note that FIG. 1 omits a flat plate-like front surface (for example, a door-like front surface that can be opened and closed) of the cabinet section 30 . As shown in FIG. 1 , the cabinet section 30 includes a flat rear surface 31 , a top plate 32 and a bottom plate 33 in addition to the front surface. The rear surface 31 serves as an installation surface on which a first housing 51 and a second housing 52, which will be described later, are installed.

The rear surface 31 is arranged behind the front surface (not shown) to face the front surface with a predetermined gap therebetween. A top plate 32 is arranged on top of the rear surface 31 (and the front panel). The faucet device main body 10 is installed on the top plate 32 . A bottom plate 33 is positioned on top of the rear face 31 (and the front face). The bottom plate 33 protrudes forward from the rear surface 31 and forms a surface higher than the floor surface F. In some cases, the wall surface of the building frame may be used as the rear surface 31 .

A water supply pipe 21 , a hot water supply pipe 22 , and a functional water supply pipe 23 , which are the piping system of the water faucet device 1 and are connected to the water faucet device main body 10 , are arranged inside the cabinet portion 30 . The water supply pipe 21 is a pipe through which water supplied from a primary water supply pipe 41 described later flows. The hot water supply pipe 22 is a pipe through which water (hot water) supplied from a primary hot water supply pipe 42 described later flows.

The functional water supply pipe 23 is connected to the first housing 51, and is a pipe through which functional water supplied from a first functional part (not shown) of a water supply system (described later) housed in the first housing 51 flows. .

In addition to the water supply pipe 21 , the hot water supply pipe 22 and the functional water supply pipe 23 , the water supply pipe portion 40 of the faucet device 1 is arranged inside the cabinet portion 30 . That is, the water supply pipe portion 40 is arranged below the water discharge portion 11 . The water supply pipe unit 40 is installed in a space (hereinafter referred to as an installation space) S surrounded by the front surface, the rear surface 31, the top plate 32 and the bottom plate 33 of the cabinet unit 30. As shown in FIG.

The water supply pipe unit 40 includes the functional water supply pipe 43 , the first housing 51 , the second housing 52 , and the connection pipe 53 described above. The primary water supply pipe 41 supplies water to the faucet device 1 from a water supply source (not shown) such as tap water. The downstream side of the water supply pipe 21 is connected to the primary water supply pipe 41 . The faucet device body 10 is supplied with water from the primary water supply pipe 41 to the water supply pipe 21 serving as the secondary water supply pipe.

Primary hot water supply pipe 42 supplies water (hot water) from a hot water supply source (not shown) such as a water heater toward faucet device 1 . The downstream side of the hot water supply pipe 22 is connected to the primary hot water supply pipe 42 . Hot water supplied from the primary hot water supply pipe 42 to the hot water supply pipe 22 serving as the secondary hot water supply pipe is supplied to the water faucet device main body 10 .

Both the primary water supply pipe 41 and the primary hot water supply pipe 42 are installed upright in front of the rear surface 31 serving as the installation surface in the installation space S. Primary water supply pipe 41 and primary hot water supply pipe 42 are arranged, for example, with a predetermined distance in the left-right direction. Primary water supply pipe 41 and primary hot water supply pipe 42 may be configured to bend upward after rear surface 31 protrudes.

The first housing 51 is, for example, a rectangular box, and accommodates a first functional part (not shown) of the water supply system. The first housing 51 accommodates the first functional unit and is installed on the rear panel 31, which is an installation surface extending in the vertical direction and rising from the floor surface F side. The first housing 51 is arranged near the primary water supply pipe 41 . In the example shown in FIG. 1 , the first housing 51 is arranged between the primary water supply pipe 41 and the primary hot water supply pipe 42 .

The first functional unit has, for example, a function of generating functional water having a sterilizing effect, and discharges the generated functional water from the water discharge unit 11 of the faucet device main body 10 toward the sink. The first functional unit discharges the functional water toward the drain port of the sink, thereby suppressing the growth of bacteria in the drain port and the inside of the drain port. Note that when the faucet device main body 10 is installed in a washbasin, for example, a toothbrush, a cup, or the like can be sterilized by discharging functional water.

The faucet device main body 10 may, for example, atomize the functional water and spray it toward the bowl portion. In this case, functional water is sprayed from nozzles provided in the water discharger 11 . The width of the mist-like functional water sprayed from the nozzle is preferably wider than the spray port of the nozzle, and the functional water is sprayed conically from the nozzle.

In addition, as a function assumed as the first function unit, a function of mixing hot water and the like can be considered. In this case, the first housing 51 is connected to the primary water supply pipe 41 and the primary hot water supply pipe 42, has an electric valve capable of adjusting the flow rate and mixing ratio inside, and is connected to the main body 2 by the secondary mixing passage. will be

The second housing 52 is, for example, a rectangular box body and accommodates a control section (not shown). The second housing 52 is installed on the rear surface 31 serving as an installation surface while accommodating the control unit. The second housing 52 is arranged below the first housing 1 in the vicinity of the primary water supply pipe 41 , preferably directly below the first housing 51 . In the example shown in FIG. 1 , the second housing 52 is arranged between the primary water supply pipe 41 and the primary hot water supply pipe 42 .

The control unit, for example, controls lighting such as an LED (not shown) provided at the tip of the water discharging unit 11 while the functional water is being discharged by the first functioning unit. For example, while the functional water is being discharged, the control unit causes the functional water existing in a predetermined range below the water discharger 11 to be irradiated with light. As a result, the user can be notified that the functional water is being discharged, and the functional water being discharged can be easily seen.

The LED provided at the tip of the water discharger 11 irradiates light, for example, in a conical shape that widens toward the end. In this case, the light irradiation range is preferably wider than the discharge (spray) range of the functional water. Thereby, the functional water present in a predetermined range below the water discharger 11 can be illuminated as a whole.

The controller includes a control board. The control unit is implemented by, for example, a CPU (Central Processing Unit), MCU (Micro Controller Unit), or the like executing a program stored in the storage unit using the RAM as a work area. The storage unit is implemented by, for example, a semiconductor memory device such as RAM (Random Access Memory) or flash memory.

The faucet device main body 10 includes, for example, a sensor section in the vicinity of the water discharge section 11 . Such a sensor section detects the user's hand held out toward the water discharging section 11 . The faucet device main body 10, for example, causes water to be discharged from the water discharge port 11 in response to detection of the hand by the sensor unit, and stops water discharge from the water discharge port 11 in response to detection of the hand by the sensor unit to stop. Thus, the faucet device body 10 may have a so-called automatic faucet function.

The connection pipe 53 is a water-permeable rigid pipe that connects the primary water supply pipe 41 and the first housing 51 and allows water supplied from the primary water supply pipe 41 to the first housing 51 to flow. The connection pipe 53 is connected to the downstream side of the primary water supply pipe 41 so as to be watertight and rotatable with respect to the primary water supply pipe 41 .

Also, the connection pipe 53 is connected to the upstream side of the first housing 51 (first functional unit) so as to be watertight and rotatable with respect to the first housing 51 . By connecting the connecting pipe 53 to the primary water supply pipe 41 and the first housing 51 in a watertight and rotatable manner, the first housing 51 can swing back and forth with respect to the primary water supply pipe 41 . Since the relative position of the primary water supply pipe 41 with respect to the rear surface 31 is fixed, in other words, the first housing 51 can swing back and forth with respect to the rear surface 31 .

Here, the connecting pipe 53 will be described with reference to FIGS. 2 and 3. FIG. FIG. 2 is a schematic exploded perspective view showing an example of the connecting pipe 53. As shown in FIG. FIG. 3 is a schematic assembly perspective view showing an example of the connecting pipe 53. As shown in FIG.

As shown in FIGS. 2 and 3, the connecting pipe 53 is a rigid pipe, for example a copper alloy pipe, as described above. Connection tube 53 includes one end 531 , the other end 532 , and a middle portion 533 . One end portion 531 is a cylindrical pipe whose axial direction extends in the left-right direction in the assembled state shown in FIG. 3, and is connected to the primary water supply pipe 41 from the left-right direction. It should be noted that the rigid body referred to here is sufficient if it can withstand water pressure while maintaining its own shape in a state where it is connected to the primary water supply pipe 41 and the first housing 51, and it may be a resin containing glass fiber. good.

One end 531 is connected to the conversion joint 411 on the most downstream side (the uppermost part of the primary water supply pipe 41 shown in FIG. 1) of the primary water supply pipe 41 (see FIG. 1). The conversion joint 411 includes a cylindrical vertically directed pipe portion 412 and a cylindrical horizontally directed pipe portion 413 extending sideways from the vertically directed pipe portion 412 . It is provided rotatably around the axis of tube 41 .

The one end portion 531 is axially sealed against the horizontal pipe portion 413 of the conversion joint 411 in the assembled (connected) state with the primary water supply pipe 41 and the first housing 51 shown in FIG. This allows rotation while maintaining watertightness.

The other end portion 532 is a cylindrical tube whose axial direction extends in the left-right direction in the assembled state shown in FIG. 3, and is connected to the first housing 51 from the left-right direction. The other end portion 532 is connected to a connection portion 511 provided at the bottom of either the left or right side surface (the left side surface in the illustrated example) of the first housing. The other end portion 532 is shaft-sealed with respect to the connecting portion 511 in the assembled state shown in FIG. This allows rotation while maintaining watertightness.

One end portion 531 and the other end portion 532 of the connecting tube 53 are not coaxial with each other, but are off-axis. A midway portion 533 exists so as to connect between one end portion 531 and the other end portion 532 whose axes are shifted from each other. The intermediate portion 533 is a cylindrical tube and extends straight between the one end portion 531 and the other end portion 532 . The intermediate portion 533 connects the one end portion 531 and the other end portion 532 so that water can flow therethrough.

The connecting pipe 53 has one end portion 531, the other end portion 532 and a middle portion 533 integrally formed, and is formed in a crank shape as a whole. In connection pipe 53 , water supplied to one end 531 is discharged from other end 532 via intermediate portion 533 . Note that the intermediate portion 533 is not limited to a crank shape perpendicular to the one end portion 531 and the other end portion 532, but may be a form in which both are connected obliquely or a form in which they are connected by a curved intermediate portion. can be

As shown in FIG. 3, the connecting portion 53 (middle portion 533) is rotatable around one end portion 531 connected to the primary water supply pipe 41 while maintaining watertightness, as indicated by the arrow in the drawing. is. Thereby, the first housing 51 can swing in the front-rear direction about the one end 531 .

Next, an installation example of the first housing 51 will be described with reference to FIGS. 4 to 7. FIG. 4 and 5 show an installation example 1 of the first housing 51, wherein FIG. 4 is a schematic perspective view and FIG. 5 is a schematic side (left side) view. 6 and 7 show an installation example 2 of the first housing 51, where FIG. 6 is a schematic perspective view and FIG. 7 is a schematic side (left side) view.

The installation example 1 shown in FIGS. 4 and 5 and the installation example 2 shown in FIGS. 6 and 7 differ in the distance from the installation surface (rear surface 31 of the cabinet section 30) of the primary water supply pipe 41. 4 and 5 show an example in which the primary water supply pipe 41 is arranged at a first distance D1 from the rear surface 31, which is the installation surface, and FIGS. 6 and 7 show the primary water supply pipe 41 , is arranged at a position a second distance D2 from. The relationship between the first distance D1 and the second distance D2 is "D1>D2".

As shown in FIGS. 4 and 5, in installation example 1, since the distance in the front-rear direction between the primary water supply pipe 41 and the first housing 51 is large, the connecting portion 53 that can swing in the front-rear direction is not provided. The first housing 51 is fixed to the rear surface 31 while tilting in the front-rear direction. In this way, when the distance in the longitudinal direction between the primary water supply pipe 41 and the rear surface 31 is relatively large, the connecting portion 53 tilts in the longitudinal direction, so that it can be dealt with.

As shown in FIGS. 6 and 7, in installation example 2, the distance between the primary water supply pipe 41 and the rear surface 31 in the front-rear direction is smaller than in installation example 1 described above, so that it can swing in the front-rear direction. The first housing 51 is fixed to the rear surface 31 with the connecting portion 53 upright (or slightly inclined in the front-rear direction). Thus, when the distance in the front-rear direction between the primary water supply pipe 41 and the rear surface 31 is small, the connecting portion 53 does not tilt in the front-rear direction.

FIG. 8 is a schematic perspective view showing an example (installation example 3) in which the first housing 51 is installed at another position. As described above, the conversion joint 411 of the primary water supply pipe 41 is rotatable around the axis L of the primary water supply pipe 41 . Therefore, the first housing 51 is rotatably attached to the primary water supply pipe 41 . For example, the first housing 51 can be installed, for example, at a symmetrical position about the axis L of the primary water supply pipe 41 . This is the installation example 3.

As shown in FIG. 8, in the installation example 3, the first housing 51 is centered on the axis L of the primary water supply pipe 41, and as indicated by the arrow in the figure, the rear surface 31 serving as the installation surface is 180 degrees. °It is installed in a rotated position. In this way, the first housing 51 can be installed on the left and right sides of the primary water supply pipe 41, improving the degree of freedom in construction.

In installation example 3, the first housing 51 is moved along with the second housing 52 when it is difficult to secure the installation position of the second housing 52. This is the case where the first housing 51 is moved when it is difficult to secure the installation position of the first housing 51 itself. For example, in a bathroom vanity, the installation position of the primary water supply pipe (shut off valve) may be located on either the left or right end of the whole. Either case can be handled.

In installation examples 1 to 3, at least a portion of the first housing 51 is in contact with the second housing 52 . The first housing 51 is preferably in face-to-face contact with the second housing 52 . In the present embodiment, when the first housing 51 of the installation example 3 is rotated, the first housing 51 and the second housing 52 are attached to each other so that the first housing 51 can be smoothly moved. A slide mechanism 54 is formed on the contact surfaces 512 and 522 .

When the thicknesses of the first housing 51 and the second housing 52 (that is, the forward dimension from the rear surface 31) are different, particularly when the thickness of the second housing is large, the first housing 51 and the second housing 52 have different thicknesses. With the rear ends of the two housings aligned, if the primary water supply pipe 41 is rotated 180° around the axis L as described above, the second housing 52 interferes. Therefore, it becomes impossible to attach the first housing 51 to the wall surface. The ability of the second housing 52 to slide relative to the first housing 51 makes it possible to attach the first housing 51 to the rear surface 31 without any problem.

Next, the slide mechanism 54 will be described with reference to FIG. FIG. 9 is a schematic perspective view showing an example of the slide mechanism 54. As shown in FIG. As described above, the slide mechanism 54 is formed on the contact surfaces of the first housing 51 and the second housing 52 . As shown in FIG. 9, the slide mechanism 54 is specifically formed on a bottom surface 51a that is a contact surface of the first housing 51 and a top surface 52a that is a contact surface of the second housing 52. As shown in FIG.

The slide mechanism 54 includes a first housing side constituent portion 541 and a second housing side constituent portion 542 . The first housing-side component 541 is a pair of engaging grooves 541a and 541b facing each other in the left-right direction, and is formed on the bottom surface 51a of the first housing 51, which is one of the contact surfaces. The pair of engaging grooves 541a and 541b are bent into a hook shape, and engaging pieces 542a and 542b, which will be described later, are fitted therein.

The second housing side constituent portion 542 is a pair of engaging pieces 542a and 542b, and is formed on the upper surface 52a of the second housing 52, which is the other contact surface. The pair of engaging pieces 542a and 542b protrude outward in the left-right direction. The pair of engagement grooves 541a and 541b and the pair of engagement pieces 542a and 542b are slidable by being guided in movement.

In this manner, the slide mechanism 54 allows sliding movement in a predetermined sliding direction because the pair of engaging grooves 541a and 541b and the pair of engaging pieces 542a and 542b are mutually slidable. This facilitates movement of the first housing 51 relative to the second housing 52 and movement of the second housing 52 relative to the first housing 51 .

FIG. 10 is a schematic perspective view showing an example of the positioning mechanism 55. As shown in FIG. As shown in FIG. 10, positioning mechanisms 55 are formed on the bottom surface 51a of the first housing 51 and the top surface 52a of the second housing 52, which are the contact surfaces described above. The positioning mechanism 55 positions the first housing 51 at a predetermined position with respect to the second housing 52 in the sliding direction of the slide movement by the slide mechanism 54 .

Further, the positioning mechanism 55 positions the second housing 52 at a predetermined position with respect to the first housing 51 with respect to the sliding direction when the slide mechanism 54 slides.

As shown in FIG. 10 , the positioning mechanism 55 includes a first housing side constituent portion 551 and a second housing side constituent portion 552 . The first housing-side constituent portion 551 is concave portions 551a and 551b formed in a pair of engaging groove portions 541a and 541b facing each other in the left-right direction. The second housing-side constituent portion 552 is convex portions 552a and 552b formed on a pair of engagement pieces 542a and 542b.

The positioning mechanism 55 positions the second housing 52 with respect to the first housing 51 by engaging the concave portions 551a and 551b with the convex portions 552a and 552b at predetermined positions. Alternatively, the first housing 51 is positioned with respect to the second housing 52 . By forming a plurality of concave portions 551a and 551b in the longitudinal direction (front-rear direction), positioning at a plurality of positions becomes possible. The plurality of positions should be determined so that the second housing 52 does not interfere with the rear surface 31 when the first housing 51 is installed at each of the left and right positions with respect to the primary side water supply pipe 41 . is preferred.

As described above, according to the faucet device 1 according to the embodiment, the rigid connection pipe 53 is watertightly and rotatably connected to the primary water supply pipe 41 and the first housing 51, respectively. The first housing 51 can be moved in the front-rear direction while the tube 41 and the first housing 51 are connected.

In addition, since the first housing 51 and the second housing 52 are arranged vertically, the second housing 52 can be easily removed because there is little obstruction by the first housing 51 and other pipes.

Also, the relative position of the first housing 51 and the second housing 52 in the front-rear direction can be adjusted by the slide mechanism 54 . This enables fine adjustment of the relative positions of the first housing 51 and the second housing 52, and improves workability when the first housing 51 and the second housing 52 are installed.

In addition, since the first housing 51 is rotatably attached to the primary water supply pipe 41, by rotating the first housing 51 around the axis L of the primary water supply pipe 41, the primary water supply pipe 41 is centered. can be installed in a symmetrical position. Thereby, the degree of freedom of construction can be improved. In addition, since the slide mechanism 54 guides the movement of the first housing 51 when rotating the first housing 51, construction becomes easy, and workability when installing the first housing 51 can be improved. . Also, even when only the second housing 52 is removed, the slide mechanism 54 guides the movement of the second housing 52 when it is removed, so workability can be improved.

Further, the slide mechanism 54 can be configured simply by including the pair of engagement grooves 541a and 541b and the pair of engagement pieces 542a and 542b.

Further, the positioning mechanism 55 can easily adjust the relative position of the first housing 51 and the second housing 52 in the front-rear direction by the slide mechanism 54 .

In the faucet device 1 described above, the sliding mechanism 54 is formed with a pair of engaging grooves 541a and 541b in the first housing 51 and a pair of engaging pieces 542a and 542b in the second housing 52. , they may be opposites. That is, the first housing 51 may be formed with a pair of engaging pieces 542a and 542b (see FIG. 9), and the second housing 52 may be formed with a pair of engaging grooves 541a and 541b (see FIG. 9). Also, the slide mechanism 54 may be provided on the left and right sides of the second housing 52 and positioned so as to be held under the first housing 51 .

Further, in the faucet device 1 described above, the positioning mechanism 55 is formed with concave portions 551a and 551b in the first housing 51 and convex portions 552a and 552b in the second housing 52. good too. That is, the projections 552a and 552b (see FIG. 10) may be formed in the first housing 51, and the recesses 551a and 551b (see FIG. 10) may be formed in the second housing 52.
