Summary of the Invention

Problems to be Solved by the Invention

[0004] In the conventional faucet device as described above, since a mounting pedestal for fixing a cartridge is attached to the rear surface side of the main body portion protruding forward from the high-back surface, the amount of protrusion of the main body portion forward (hereinafter referred to as forward protrusion) can be suppressed, and the usability of the bowl portion can be improved. On the other hand, since the mounting pedestal is attached to the rear surface side of the main body portion, it is impossible to approach the main body portion and the mounting pedestal from the front side, and the workability and maintainability are low.

[0005] One aspect of the embodiment aims to provide a faucet device capable of achieving both suppression of the forward protrusion of the main body portion and workability and maintainability.

Means for Solving the Problems

[0006] A faucet device according to one embodiment is a faucet device provided on or above a high back surface extending above a bowl portion, comprising: a main body portion which is embedded in the rear side of the high back surface and protrudes forward from the high back surface; a single cartridge housed in the main body portion for mixing hot and cold water; a primary water supply pipe which supplies hot and cold water from a water source to the single cartridge; and a mounting base which has a first connection portion to which the primary water supply pipe is connected radially and to which the single cartridge is fixed, wherein the main body portion has a hole in the lower surface of the portion embedded in the high back surface through which the primary water supply pipe is inserted, and the mounting base is fixed from the inside of the main body portion such that the first connection portion is positioned above the hole.

[0007] With this configuration, the space required behind the mounting base for passing the primary water supply pipe through the space formed on the rear side of the high back surface is reduced. This reduces the amount of forward protrusion (overhang) of the main body, and also allows the mounting base to be attached and detached from the front side of the main body, improving ease of installation and maintenance. In this way, it is possible to achieve both reduced forward protrusion of the main body and ease of installation and maintenance.

[0008] Furthermore, in the faucet device described above, the fixing surface between the mounting base and the main body is formed on the rearward side of the first connection portion.

[0009] With this configuration, the entire mounting base can be positioned inside the main body and fixed from within the main body, thus minimizing the space required behind the mounting base. Furthermore, it prevents interference between the primary water supply pipe, which is connected to the mounting base radially, and the fixing surface between the mounting base and the main body, which would otherwise make it difficult to easily attach or detach the mounting base from the front of the main body.

[0010] Furthermore, in the faucet device described above, the rear surface of the mounting base is in contact with the rear inner surface of the main body.

[0011] With this configuration, the amount of protrusion from the rear inner surface of the main body of the single cartridge and mounting base can be minimized, and the forward protrusion of the main body can be more effectively suppressed.

[0012] Furthermore, the faucet device described above is characterized in that it is provided with a fixing member for fixing the mounting base to the main body, the fixing member being plate-shaped and positioned between the mounting base and the main body.

[0013] With this configuration, since the fixing member that secures the mounting base is a separate component from the mounting base, it is possible to suppress the increase in thickness (length) of the mounting base at the front and rear, which is necessary to ensure strength, and reduce the protrusion of the main body. In addition, since the fixing member is plate-shaped (plate material), it is possible to securely fix the main body and the mounting base while suppressing an increase in their front and rear lengths when fixing them together.

[0014] Furthermore, the faucet device described above is characterized by comprising a water supply pipe retaining member for fixing the primary water supply pipe connected to the first connection portion, the mounting base having a fixing portion for fixing the water supply pipe retaining member and a fixing portion for fixing the fixing member, and the water supply pipe retaining member being integrally formed with the fixing member.

[0015] With this configuration, since the fixing member and the water supply pipe retaining member are integrally formed, the fixing portion (screw hole) provided on the mounting base for fixing the fixing member can also be used as a fixing portion for fixing the water supply pipe retaining member. In other words, the fixing portion (screw hole) for the fixing member can be used interchangeably with the fixing portion for the water supply pipe retaining member. Therefore, the number of fixing portions present in the circumferential direction of the mounting base can be reduced without reducing the total number of fixing portions for the water supply pipe retaining member. This makes it possible to more effectively suppress the forward protrusion of the mounting base while ensuring safety.

[0016] Furthermore, the faucet device described above comprises a water outlet having a spout for discharging hot and cold water, and a secondary water supply pipe that guides the hot and cold water flowing out from the single cartridge to the water outlet, and the mounting base is characterized in that it has a second connection part for connecting the secondary water supply pipe at a position different from the first connection part in its circumferential direction.

[0017] This configuration allows for a reduction in the space required behind the mounting base for arranging the secondary water supply pipe, thereby more effectively suppressing the forward protrusion of the main body.

[0018] Furthermore, the faucet device described above is equipped with a cartridge retaining member that holds the single cartridge in place from the front side of the single cartridge, and the cartridge retaining member is characterized by comprising a cartridge retaining body and a water intrusion prevention member that prevents water from entering from the front side of the cartridge retaining body.

[0019] With this configuration, it is possible to easily prevent water (hot or cold water) from entering the interior of the high back panel from the outside of the main unit via the single cartridge.

[0020] Furthermore, in the faucet device described above, the water intrusion prevention member is characterized in that it is detachable from the cartridge retaining body.

[0021] With this configuration, the water intrusion prevention member can be attached to or detached from the cartridge retainer body before attaching or detaching the cartridge retainer member. By attaching or detaching the water intrusion prevention member in advance, the water intrusion prevention member does not get in the way of attaching or detaching the cartridge retainer member, resulting in improved maintainability.

[0022] Furthermore, in the faucet device described above, the water intrusion prevention member is characterized in that it extends radially outward from the cartridge retaining body, and its peripheral edge protrudes forward.

[0023] According to such a configuration, the water (hot and cold water) that has passed through the single cartridge can be more reliably blocked, and water intrusion can be more effectively suppressed.

[0024] Further, in the faucet device described above, the water intrusion prevention member is characterized by having an asymmetrical shape in the vertical direction.

[0025] According to such a configuration, since it is also a shape that focuses on preventing the intrusion of water (hot and cold water) from the part where water intrusion is likely to occur, even when the water intrusion prevention member is arranged inside the main body part, it is possible to suppress the enlargement of the main body part.

Effects of the Invention

[0026] According to one aspect of the embodiment, it is possible to achieve both suppression of the above-mentioned main body part and workability and maintainability.

However, the present invention is not limited to the embodiments described below.

[0029] <Overall configuration of the faucet system> First, the overall configuration of the faucet device 1 according to this embodiment will be described with reference to Figure 1. Figure 1 is a schematic perspective view showing the faucet device 1 according to this embodiment.

[0030] Note that each figure, including Figure 1, shows a three-dimensional Cartesian coordinate system that includes the Z-axis, with the vertically upward direction (upward) being the positive direction. For the sake of explanation, below, the positive direction of the X-axis is defined as left, the negative direction of the X-axis as right, the positive direction of the Y-axis as forward, and the negative direction of the Y-axis as backward. Therefore, below, the X-axis direction will be referred to as the left-right direction, the Y-axis direction as the front-back direction, and the Z-axis direction as the up-down direction.

[0031] Furthermore, the faucet device 1 is installed, for example, on a vanity unit. The vanity unit includes the faucet device 1 and the washbasin, as well as, for example, a support base, a cabinet, and a lighting device. The washbasin comprises a bowl section (not shown) and a high back surface 2 (see Figure 2). The bowl section receives hot and cold water (hereinafter referred to as "water," and this "water" includes heated water) discharged from the faucet device 1.

[0032] The high back surface 2 is a surface that extends upward from the rear end of the bowl portion. The faucet device 1 is installed on the high back surface 2. The faucet device 1 protrudes forward from the high back surface 2. Alternatively, the faucet device 1 may be installed above the high back surface 2. In this case as well, the faucet device 1 protrudes forward from the high back surface 2, that is, toward the bowl portion.

[0033] As shown in Figure 1, the faucet device 1 comprises a housing 11, a water outlet 12, and an operating unit 13. The housing 11 is formed in a long shape in the left-right direction (for example, rectangular). The rear side of the housing 11 is attached, for example, to a high back surface 2 or above the high back surface 2, and is provided to protrude forward from the high back surface 2.

[0034] The housing 11 houses the base end (rear end) of the water discharge section 12 and the operating section 13, which will be described later. The housing 11 also houses, for example, a part of the water supply hose (also called a pull-out hose) to which the water discharge section 12 is attached via the secondary water supply pipe 62 (see Figure 3), which will be described later. A flexible hose is used for the water supply hose.

[0035] The spout 12 discharges water towards the bowl located below the faucet device 1. The spout 12 is a so-called spout. The spout 12 has a spout 12a from which water is discharged. Furthermore, as described above, the spout 12 is connected to the tip of the water supply hose housed in the housing 11 and is configured to be able to be pulled out, for example, towards the user facing the faucet device 1.

[0036] The water outlet 12 is connected to a water source (not shown) via a single cartridge 30 (see Figure 2), which will be described later. The water discharged from the water outlet 12 is, for example, tap water.

[0037] The operating unit 13 includes an operating lever 13a. The operating unit 13 adjusts the flow rate and temperature of the water discharged from the water outlet 12 in response to the user's operation of the operating lever 13a. The upper end of the operating lever 13a is pivotally supported on the main body 20 so that it can swing, for example, in the front-to-back and left-to-right directions.

[0038] The operating lever 13a adjusts the flow rate of water from the water outlet 12 by swinging it, for example, in the forward and backward direction, and adjusts the temperature of the water from the water outlet 12 by swinging it, for example, in the left and right direction. Note that the manner in which the flow rate and temperature are adjusted by the operating unit 13 is not limited to the operating lever 13a, but may be any manner. Note that the temperature adjustment of the water discharged from the water outlet 12 may be performed by an adjustment unit separate from the operating unit 13, and the operating unit 13 only needs to be able to adjust the flow rate of water discharged from the water outlet 12.

[0039] Furthermore, the control unit 13 is equipped with the aforementioned single cartridge 30 for mixing hot and cold water. The main body 20 of the control unit 13, which will be described later, is connected to a primary water supply pipe 61 that supplies water from the water source to the single cartridge 30. The primary water supply pipe 61 extends upward on the rear side of the high back surface 2 and is connected to the main body 20 from below.

[0040] <Configuration of the main unit> Next, the configuration of the main body 20 will be described with reference to Figures 2 to 5. Figure 2 is a schematic side cross-sectional view showing the main body 20. Figure 3 is a cross-sectional view taken along line III-III in Figure 2, and is a schematic cross-sectional view of the mounting base 40. Figure 4 is a schematic perspective view showing the water supply pipe retaining member 52. Figure 5 is an explanatory diagram regarding the fixing of the mounting base 40.

[0041] As shown in Figures 2-5, the main body 20 comprises a single cartridge 30, a mounting base 40, a fixing member 51, a water supply pipe retaining member 52, a primary water supply pipe 61, and a secondary water supply pipe 62.

[0042] The main body 20 is positioned behind the operating lever 13a. The operating lever 13a is attached to the front end of the main body 20. The main body 20 is installed with at least a portion embedded in the rear side of the high back surface 2. Therefore, the main body 20 is provided to protrude forward from the high back surface 2. The main body 20 is part of the housing 11 that houses the single cartridge 30 and the mounting base 40.

[0043] Furthermore, the main body 20 has a hole 21 on the underside of the rear portion embedded in the high back surface 2, through which the primary water supply pipe 61, which will be connected to the mounting base 40 described later, is inserted.

[0044] The single cartridge 30 mixes the hot and cold water supplied from the primary water supply pipe 61. The single cartridge 30 adjusts the water flow rate and water temperature according to the amount the operating lever 13a is operated on. The water whose temperature and flow rate have been regulated by the single cartridge 30 flows out from the secondary water supply pipe 62 towards the discharge section 12 (see Figure 1).

[0045] The mounting base 40 houses the single cartridge 30 inside and is fixed to the main body 20 at the rear of the single cartridge 30. The mounting base 40 is provided with a first connection part 41. The first connection part 41 is provided on the lower surface of the mounting base 40. The primary water supply pipe 61 is connected to the first connection part 41 from below in the radial direction. That is, the primary water supply pipe 61 is connected to the mounting base 40 from below in the radial direction.

[0046] The mounting base 40 is fixed from inside the main body 20 such that the first connecting portion 41 is positioned above the hole 21. The fixing surface 43 between the mounting base 40 and the main body 20 is formed on the rearward side of the first connecting portion 41. In this case, the rear surface 43a of the mounting base 40 abuts against the rearward inner surface 43b of the main body 20. The rearward inner surface 43b of the main body 20 is also the rearward surface of the housing 11. In addition, a fixing member 51, which will be described later, may be placed between the rear surface 43a of the mounting base 40 and the rearward inner surface 43b of the main body 20.

[0047] Furthermore, a secondary water supply pipe 62 is connected to either the left or right side of the mounting base 40 (either the left or right side facing the water outlet 12).

[0048] Furthermore, the mounting base 40 is provided with a second connection portion 42 for connecting the secondary water supply pipe 62 at a position different from the first connection portion 41 in the circumferential direction when viewed from the front. The second connection portion 42 is provided on the rear side of the mounting base 40, similar to the first connection portion 41.

[0049] The fixing member 51 is a member for fixing the mounting base 40 to the main body 20. The fixing member 51 is a plate-shaped member and is positioned between the mounting base 40 and the main body 20. The fixing member 51 is fixed to the mounting base 40 via a fixing portion (hereinafter referred to as the first fixing portion) 44 of the mounting base 40. The first fixing portion 44 is, for example, a hole (screw hole) through which a fastener 44a such as a screw is inserted.

[0050] The water supply pipe retaining member 52 is a member for fixing the primary water supply pipe 61 connected to the first connection part 41. The water supply pipe retaining member 52 is a plate-shaped member and is positioned on the lower rear surface of the mounting base 40. The water supply pipe retaining member 52 is formed integrally with the fixing member 51. Specifically, the water supply pipe retaining member 52 is formed by bending forward so as to be perpendicular to the surface direction of the fixing member 51.

[0051] Furthermore, as shown in Figure 3, the water supply pipe retaining member 52 fixes the primary water supply pipe 61 connected to the first connection part 41 so as to prevent it from coming loose. The water supply pipe retaining member 52 has a semicircular notch, and when the primary water supply pipe 61 is passed through the notch, it is fixed by being sandwiched between the retaining member 52 and the flange portion at the upper end of the primary water supply pipe 61.

[0052] Furthermore, the water supply pipe retaining member 52 is fixed to the mounting base 40 via a fixing portion (hereinafter referred to as the second fixing portion) 45 of the mounting base 40. The second fixing portion 45 is, for example, a hole (screw hole) through which a fastener 45a such as a screw is inserted.

[0053] Furthermore, a water supply pipe retaining member 53 is integrally formed on the fixing member 51 for fixing the secondary water supply pipe 62 connected to the second connection part 42. Similar to the water supply pipe retaining member 52, the water supply pipe retaining member 53 fixes the secondary water supply pipe 62 connected to the second connection part 42 in a manner that prevents it from coming loose, as shown in Figure 3. The water supply pipe retaining member 53 has a semicircular notch, and with the secondary water supply pipe 62 passed through the notch, it is clamped and fixed between the retaining member 53 and the flange portion of the end (side end) of the secondary water supply pipe 62.

[0054] Furthermore, as shown in Figure 5, the fixing member 51 is fixed to the rear inner surface 43b of the main body 20 (the rear surface of the housing 11) through a hole (screw hole) 46 through which a fastener 46a such as a screw is inserted.

[0055] As described above, the primary water supply pipe 61 is a water supply pipe for supplying water from the water source to the single cartridge 30 via the mounting base 40. The primary water supply pipe 61 comprises a water supply pipe through which cold water flows and a water supply pipe through which hot water flows. As described above, the primary water supply pipe 61 is connected to the lower surface (first connection part 41) of the mounting base 40.

[0056] The secondary water supply pipe 62 is a pipe that forms a flow path that guides the water flowing out from the single cartridge 30 to the water outlet 12, and as described above, it is connected to either the left or right side of the mounting base 40 (either the left or right side that leads to the water outlet 12).

[0057] As described above, with the faucet device 1 according to the embodiment described above, the space S2 behind the mounting base 40 required to pass the primary water supply pipe 61 through the space S1 formed on the rear side of the high back surface 2 is reduced. As a result, the amount of forward protrusion (forward projection) D of the main body 20 can be reduced, and the mounting base 40 can be attached and detached from the front side of the main body 20, improving ease of installation and maintenance. Thus, with the faucet device 1 according to the embodiment described above, it is possible to achieve both suppression of the forward projection D of the main body 20 and ease of installation and maintenance.

[0058] Furthermore, since the mounting base 40 can be fixed from inside the main body 20 with the entire mounting base 40 positioned inside the main body 20, the space S2 on the rear side of the mounting base 40 can be minimized. In addition, the primary water supply pipe 61 connected to the mounting base 40 from the radial direction can be prevented from interfering with the fixing surface 43 between the mounting base 40 and the main body 20, which would make it difficult to easily attach and detach the mounting base 40 from the front side of the main body 20.

[0059] Furthermore, the amount of protrusion from the rear inner surface 43b of the main body 20 of the single cartridge 30 and the mounting base 40 can be minimized, and the forward projection D of the main body 20 can be suppressed more effectively.

[0060] Furthermore, since the fixing member 51 that secures the mounting base 40 is a separate component from the mounting base 40, it is possible to suppress the increase in thickness (length) of the mounting base 40 at the front and rear to ensure strength, thereby reducing the protrusion D of the main body 20. Also, since the fixing member 51 is a plate-shaped component, when fixing the main body 20 and the mounting base 40, it is possible to securely fix the main body 20 and the mounting base 40 while suppressing an increase in their front and rear lengths.

[0061] Furthermore, since the fixing member 51 and the water supply pipe retaining member 52 are integrally formed, the first fixing part (screw hole) 44 provided on the mounting base 40 for fixing the fixing member 51 can also be used as a second fixing part (screw hole) 45 for fixing the water supply pipe retaining member 52. In other words, the first fixing part (screw hole) 44 for the fixing member 51 can be used interchangeably as the second fixing part (screw hole) 45 for the water supply pipe retaining member 52. As a result, the number of fixing parts present in the circumferential direction of the mounting base 40 can be reduced without reducing the total number of fixing parts (second fixing parts 45) for the water supply pipe retaining member 52. This makes it possible to more effectively suppress the forward projection D of the mounting base 40 while ensuring safety.

[0062] Furthermore, the space S2 at the rear of the mounting base 40, which is necessary for arranging the secondary water supply pipe 62, can be reduced, and the forward protrusion D of the main body 20 can be more effectively suppressed.

[0063] <Water intrusion prevention material> Next, the water intrusion prevention member 72 will be described with reference to Figures 6-8. Figure 6 is a schematic perspective view showing the cartridge retaining member 70. Figures 7 and 8 are schematic perspective views showing the water intrusion prevention member 72.

[0064] As shown in Figure 6, the main body 20 (see Figure 2) further includes a cartridge retaining member 70. The cartridge retaining member 70 is a member provided to hold down the single cartridge 30. The cartridge retaining member 70 is attached to the front of the single cartridge 30 and holds down the single cartridge 30 from the front.

[0065] The cartridge retaining member 70 comprises a cartridge retaining body 71 and a water intrusion prevention member 72. The cartridge retaining body 71 is formed in a cylindrical shape and is fitted into the front end of the main body 20 (see Figure 2). The cartridge retaining body 71 holds the single cartridge 30 from the front with the shaft portion 31 for connecting the operating lever 13a (see Figure 2), which extends forward from the single cartridge 30, inserted in the front-to-back direction.

[0066] The water intrusion prevention member 72 is a member that prevents water from entering the cartridge retainer body 71 from the front. In a front view, the water intrusion prevention member 72 is provided so as to surround the outer circumference of the cartridge retainer body 71 and extends radially outward from the cartridge retainer body 71. In addition, the peripheral edge 72a of the water intrusion prevention member 72 is bent and protrudes forward.

[0067] As shown in Figure 7, the water intrusion prevention member 72 is detachable from the cartridge retaining body 71. The water intrusion prevention member 72 is C-shaped in a front view, and a claw portion 72b is provided at its tip. As shown in Figure 8, the rotation of the water intrusion prevention member 72 in the circumferential direction is restricted when the claw portion 72b fits into a recess 71a provided on the outer circumferential surface of the mounting base 40.

[0068] Furthermore, the water intrusion prevention member 72 is shaped to extend radially outward from the cartridge retaining body 71, asymmetrically in the vertical direction. This shape prevents water entering from the front of the cartridge retaining body 71 from penetrating from above the single cartridge 30 to the back (rear) side of the main body 20. By giving the shape of the water intrusion prevention member 72 anisotropy in this way, it is possible to prioritize preventing water intrusion in certain areas and not in others, and it is possible to prevent the main body 20 from becoming larger in order to accommodate the water intrusion prevention member 72.

[0069] As described above, according to the faucet device 1 of the above embodiment, by providing a water intrusion prevention member 72, it is possible to suppress water from entering the interior of the high back surface 2 from the outside of the main body 20 via the single cartridge 30 with a simple configuration.

[0070] Furthermore, when attaching or detaching the cartridge retaining member 70, the water intrusion prevention member 72 can be attached or detached from the cartridge retaining body 71 in advance. By attaching or detaching the water intrusion prevention member 72 in advance in this way, the water intrusion prevention member 72 does not get in the way when attaching or detaching the cartridge retaining member 70, resulting in improved maintainability.

[0071] Furthermore, the water intrusion prevention member 72 extends radially outward from the cartridge retaining body 71, and its peripheral edge 72a protrudes forward, which allows it to more reliably block water that has traveled through the single cartridge 30, thereby more effectively suppressing water intrusion.

[0072] Furthermore, since the water intrusion prevention member 72 has an asymmetrical shape in the vertical direction, and this shape is designed to primarily prevent water from entering from areas prone to water intrusion, even when the water intrusion prevention member 72 is placed inside the main body 20, it is possible to suppress an increase in the size of the main body 20.

[0073] In addition, the above-described embodiment may be further equipped with a sensor, for example, to be an automatic faucet device that automatically stops water flow based on the detection of an object, such as the user's hand, near the water outlet 12a by the sensor.

[0074] Further effects and modifications can be readily derived by those skilled in the art. Therefore, broader aspects of the present invention are not limited to the specific details and representative embodiments expressed and described above. Accordingly, various modifications are possible without departing from the spirit or scope of the overall concept of the invention as defined by the appended claims and their equivalents.
