[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, like components are designated by like reference numerals and detailed descriptions thereof will be omitted where appropriate. FIG. 1 is a perspective view showing a plumbing device according to an embodiment. FIG. 2 is a front view of the faucet device of the plumbing equipment. FIG. 3 is a perspective view showing a faucet device of a plumbing device. 4 is a side view of the water faucet device as seen from the direction of arrow AA in FIG. As shown in Fig. 1, the plumbing device 10 is a vanity unit. The plumbing device 10 includes a washbasin 20, a support base 30, a mirror cabinet 40, and a faucet device 50. The plumbing device 10 is not limited to a vanity unit, and may also be, for example, a hand washing basin in a kitchen or toilet room.

[0019] In this specification, the terms "up," "down," "right," and "left" refer to up, down, right, and left, respectively, relative to a person standing in front of the plumbing device 10 and looking at the plumbing device 10. In this specification, the direction from the plumbing device 10 toward the person standing in front of the plumbing device 10 is referred to as the "front" direction, and the opposite direction is referred to as the "rear" direction.

[0020] The washbasin 20 has a bowl portion 22, a counter 24, and a back guard portion 26. The bowl portion 22 is formed in a concave shape that is recessed downward. The bowl portion 22 has a drain outlet 22a. The drain outlet 22a is provided at the bottom of the bowl portion 22. The drain outlet 22a is connected to a drain pipe, and water discharged into the bowl portion 22 flows into the drain pipe. The bowl portion 22 has a drainage gradient that slopes downward toward the drain outlet 22a.

[0021] The counters 24 are located on both the left and right sides and on the front side of the bowl portion 22. In other words, the counters 24 surround the bowl portion 22 on the front side of the back guard portion 26. The counters 24 are, for example, horizontal surfaces extending horizontally from the upper end of the bowl portion 22.

[0022] The back guard portion 26 extends upward from the rear ends of the bowl portion 22 and the counter 24. The counter 24 and the back guard portion 26 are provided as needed and can be omitted. The shape of the washbasin 20 may be any shape that has at least the bowl portion 22.

[0023] The support base 30 is placed on the floor F of the building structure. For example, the support base 30 is placed on the floor of the room in which the plumbing device 10 is installed. The washbasin 20 is provided on the support base 30. The support base 30 supports the washbasin 20. The support base 30 has, for example, a base portion 30a and two drawers 30b. The base portion 30a is, for example, in the shape of a roughly rectangular parallelepiped open box with openings at the front and top. The upper opening of the base portion 30a is blocked by the washbasin 20. At least a portion of the bowl portion 22 extends into the base portion 30a through the upper opening of the base portion 30a.

[0024] Each drawer 30b is shaped like a roughly rectangular parallelepiped open box with an opening at the top. Each drawer 30b is supported on the base 30a so as to be movable forward and backward, and moves between a storage position (the position shown in FIG. 1) where it is stored within the base 30a and a pull-out position where it is pulled out forward from the base 30a. When in the storage position, each drawer 30b closes the front opening of the base 30a. When in the pull-out position, each drawer 30b can store items inside.

[0025] In this way, the support base 30 also functions as a cabinet capable of storing items. In other words, the support base 30 is a lower cabinet (floor cabinet). The number of drawers is not limited to two, but may be one, or three or more. Furthermore, the support base 30 is not limited to a drawer-type cabinet, but may be a door-type cabinet.

[0026] The support stand 30 does not necessarily have to have a storage function. The support stand 30 may have any configuration that can support the washbasin 20. The washbasin 20 may also be attached directly to a wall of a building frame (for example, a wall surface of a bathroom or changing room). In other words, the support stand 30 is provided as needed and can be omitted.

[0027] The mirror cabinet 40 is disposed above the support base 30 via the faucet device 50. The mirror cabinet 40 has an upper cabinet 41 and three mirror doors 42 to 44. A mirror is provided on the front of each of the mirror doors 42 to 44. The number of mirror doors provided on the mirror cabinet 40 is not limited to three, and may be one, two, or four or more.

[0028] The mirror cabinet 40 is attached to a support such as a wall of a building frame by fastening members such as bolts. However, the mirror cabinet 40 may be attached to and supported by a support other than a wall (for example, a separately provided counter, panel, or support stand 30).

[0029] The faucet device 50 is disposed above the bowl portion 22 and the back guard portion 26. That is, the faucet device 50 is provided between the back guard portion 26 and the mirror cabinet 40. The faucet device 50 has a housing 52. The housing 52 forms the outer shell of the faucet device 50. The housing 52 is disposed above the bowl portion 22 and the back guard portion 26. For example, the upper end of the back guard portion 26 may be in contact with the housing 52. The housing 52 is attached directly or indirectly to the wall of the building frame by a fixing member such as a bolt.

[0030] Housing 52 has a main body 53 located above back guard 26, and a protrusion 55 protruding forward from main body 53. As shown in Figures 1 to 4, main body 53 is provided with a water discharger 60 that discharges hot and cold water, a flow rate adjuster 62 that adjusts the flow rate of water discharged from water discharger 60, and a functional water discharger 64 that atomizes the functional water and sprays it onto bowl 22.

[0031] The water discharge part 60 protrudes from the underside 53a of the main body part 53. The water discharge part 60 is a so-called spout, and has a water outlet 60a that discharges hot and cold water toward the bowl part 22 of the washbasin 20. As shown in Figure 3, the inside of the main body part 53 is provided with a case 54 that stores a hose (not shown) connected to the water discharge part 60, an electrical device (control part 66), and the like.

[0032] Flow rate adjustment unit 62 adjusts the flow rate of water discharged from water discharge unit 60. Flow rate adjustment unit 62 also adjusts the temperature of water discharged from water discharge unit 60. Flow rate adjustment unit 62 has a flow rate adjustment lever 62a that protrudes from underside 53a of main body 53. Flow rate adjustment unit 62 adjusts the flow rate and temperature of water discharged from water discharge unit 60 in response to operation of flow rate adjustment lever 62a by the user. The manner in which flow rate and temperature are adjusted by flow rate adjustment unit 62 is not limited to flow rate adjustment lever 62a, and any manner that can adjust the flow rate and temperature may be used.

[0033] Water discharger 60 is connected to a water supply pipe and a hot water supply pipe via a hot and cold water mixing unit or the like in the internal space of housing 52 or support base 30. The water discharged from water discharger 60 is, for example, clean water (tap water). The temperature of the water discharged from water discharger 60 may be adjusted by an adjustment unit separate from flow rate adjustment unit 62. It is sufficient for flow rate adjustment unit 62 to be able to at least adjust the flow rate of water discharged from water discharger 60.

[0034] Main body 53 of housing 52 covers at least a portion of water discharger 60 and flow rate adjuster 62. Main body 53 is, for example, box-shaped and extends in the left-right direction. Water discharger 60 is attached directly or indirectly to main body 53. Main body 53 holds at least a portion of water discharger 60 and flow rate adjuster 62 within its internal space.

[0035] The functional water discharger 64 discharges functional water having a disinfecting effect into the bowl portion 22. The functional water discharger 64 is provided on the lower surface 53a of the main body portion 53 and discharges the functional water downward. The functional water discharger 64 discharges the functional water, for example, toward the drain outlet 22a of the bowl portion 22.

[0036] For example, by discharging functional water from the functional water discharge unit 64 into the bowl unit 22, it is possible to suppress the growth of bacteria in the drain outlet 22a of the bowl unit 22 and inside the drain outlet 22a. In the plumbing device 10 and the faucet device 50, for example, the drain outlet 22a and the inside of the drain outlet 22a can be sterilized, thereby keeping the washbasin 20 clean. In addition, by discharging functional water onto toothbrushes, cups, etc., these can also be sterilized.

[0037] The protrusion 55 protrudes forward from a lower position of the main body 53. The protrusion 55 is formed in a hollow box shape. For example, the interior of the protrusion 55 is connected to the interior of the main body 53. The protrusion 55 extends, for example, from the left end to the right end of the main body 53. In this example, the housing 52 has the same width as both the left and right ends of the counter 24 of the washbasin 20.

[0038] As shown in FIG. 4, a touch switch 70 is provided inside the protrusion 55. The touch switch 70 is an electrostatic sensor (capacitance sensor) that detects, for example, a fingertip and changes capacitance. In this example, the front surface of the touch switch 70 serves as the detection unit. The touch switch 70 may also be a microwave sensor, a millimeter-wave sensor, an infrared (photoelectric) sensor, an ultrasonic sensor, or the like. The touch switch 70 may also detect a finger approaching the operation surface 57a. In other words, the touch switch 70 may be capable of performing operation input without contact by simply placing a finger over the operation surface 57a. The touch switch 70 is electrically connected to a control unit 66 that constitutes an electrical device and transmits the detected capacitance (command signal) to the control unit 66. The control unit 66 activates various functional units (such as functional water discharge and water temperature adjustment) based on the command signal transmitted from the touch switch 70.

[0039] The protruding portion 55 has an upper surface 56 extending forward from the front surface 53b of the main body portion 53, a front surface 57 extending downward from the tip of the upper surface 56, and a restraining surface 58 extending rearward from the lower end of the front surface 57. The upper surface 56 is, for example, a horizontally flat surface on which an item such as a cup or a toothbrush can be placed.

[0040] A front surface 57 of the protrusion 55 rises upward from the tip of the suppression surface 58. The front surface 53b of the main body 53 and the front surface 57 of the protrusion 55 form the front surface of the housing 52. In other words, the front surface of the housing 52 is formed in a stepped shape in the front-to-rear direction by the front surface 53b of the main body 53 and the front surface 57 of the protrusion 55.

[0041] The front surface 57 of the protrusion 55 has an operation surface 57a of the touch switch 70. The operation surface 57a is located in front of the touch switch 70. The touch switch 70 detects whether or not a finger has touched the operation surface 57a. The operation surface 57a has multiple touch elements. The touch elements are used to, for example, switch between an automatic faucet and a manual faucet, dispense functional water, and dispense water until the set temperature is reached.

[0042] Operation surface 57a is a surface facing forward (for example, a surface at least a portion of which is visible when viewed from the front). As shown in FIG. 4, in this example, front surface 57 and operation surface 57a are surfaces that stand upright in the vertical direction. In this example, operation surface 57a is located between and above water discharger 60 and flow rate adjuster 62. Operation surface 57a is located above water outlet 60a of water discharger 60. Operation surface 57a does not have to be directly above water outlet 60a, and may be shifted left or right.

[0043] The suppression surface 58 extends from the underside 53a of the main body 53 to the lower end of the front surface 57 of the protrusion 55. The suppression surface 58 forms the underside of the protrusion 55. The suppression surface 58 is located between the operation surface 57a and the water outlet 60a. The suppression surface 58 suppresses, for example, water W discharged from the water outlet 60a from adhering to the operation surface 57a.

[0044] The suppression surface 58 faces downward relative to the operation surface 57a. As shown in FIG. 4, in this example, the operation surface 57a faces forward, and the suppression surface 58 faces downward. The suppression surface 58 extends from the lower surface 53a of the main body 53 toward the front of the water outlet 60a. In other words, the suppression surface 58 covers the upper side of the water outlet 60 (water outlet 60a). As shown in FIG. 4, the operation surface 57a is located forward relative to the water outlet 60a.

[0045] FIG. 5 is an explanatory diagram showing a state in which water splashes when washing hands. For ease of explanation, FIG. 5 shows the housing 52, the water discharger 60, and the like in a simplified manner.

[0046] As shown in FIG. 5, water W splashed when washing hands is blocked by suppression surface 58, which faces downward relative to operation surface 57a. This prevents water W from adhering to operation surface 57a. This prevents water W from adhering to operation surface 57a and causing false detection by touch switch 70. In addition, suppression surface 58 extends further forward than water outlet 60a. This allows suppression surface 58 to more effectively prevent water W splashed from hands from adhering to operation surface 57a.

[0047] 2, the width L1 of the suppression surface 58 is larger than the width L2 of the operation surface 57a. As a result, the suppression surface 58 can effectively suppress water W that splashes toward the operation surface 57a from the side (diagonally downward) from adhering to the operation surface 57a. In this example, the suppression surface 58 extends across both ends of the counter 24 in the left-right direction. As a result, the suppression surface 58 can efficiently block the water W that splashes in the washroom space between both ends of the counter 26 and the upper end of the front surface 57 of the protrusion 55.

[0048] As shown in FIGS. 4 and 5, a water exposure prevention portion 59 is provided above the operation surface 57a. The water exposure prevention portion 59 prevents water W from flowing from above toward the operation surface 57a. In this example, the water exposure prevention portion 59 is a protrusion that protrudes upward between the upper surface 56 of the protruding portion 55 and the front surface 57. The water exposure prevention portion 59 is positioned at least directly above the operation surface 57a and is formed to be longer than the lateral width L2 of the operation surface 57a. This allows the water exposure prevention portion 59 to prevent water W adhering to the upper surface 56 from flowing from the upper surface 56 toward the operation surface 57a. As a result, it is possible to prevent water W from adhering to the operation surface 57a and causing the touch switch 70 to make a false detection.

[0049] 5, the water exposure prevention portion 59 protrudes upward, so that when the article 100 is placed on the upper surface 56 and the water exposure prevention portion 59, a predetermined distance can be maintained between the article 100 and the touch switch 70. As a result, the water exposure prevention portion 59 can prevent the touch switch 70 from making a false detection when the article 100 is, for example, an electronic device or a metal cup that would cause the touch switch 70 to make a false detection. The water exposure prevention portion 59 may be provided as needed.

[0050] FIG. 6 is an explanatory diagram similar to FIG. 5, showing a plumbing device according to a first modified example. FIG. 7 is an explanatory diagram similar to FIG. 5, showing a plumbing device according to a second modified example. FIG. 8 is an explanatory diagram similar to FIG. 5, showing a plumbing device according to a third modified example. FIG. 9 is an explanatory diagram similar to FIG. 5, showing a plumbing device according to a fourth modified example. FIG. 10 is an explanatory diagram similar to FIG. 5, showing a plumbing device according to a fifth modified example. FIG. 11 is an explanatory diagram similar to FIG. 5, showing a plumbing device according to a sixth modified example. 6 to 10 show examples of the relationship between the shapes of the operation surface and the prevention surface, in which the water damage prevention section 59 is omitted.

[0051] 6, the operation surface 80 is inclined downward from the front to the rear. Even in this case, the suppression surface 58 faces downward more than the operation surface 80, and therefore the water W discharged from the water outlet 60a can be prevented from adhering to the operation surface 80.

[0052] 7, the operation surface 81 is inclined upward from the front to the rear. Even in this case, the suppression surface 58 faces downward relative to the operation surface 81, and therefore the water W discharged from the water outlet 60a can be prevented from adhering to the operation surface 81.

[0053] 8, the suppression surface 82 is inclined downward from the front to the rear. Even in this case, the suppression surface 82 faces downward relative to the operation surface 57a, and therefore the water W discharged from the water outlet 60a can be prevented from adhering to the operation surface 57a.

[0054] 9, the suppression surface 83 is inclined upward from the front to the rear. Even in this case, the suppression surface 83 faces downward relative to the operation surface 57a, and therefore the water W discharged from the water outlet 60a can be prevented from adhering to the operation surface 57a.

[0055] As in a fifth modified example shown in Fig. 10, the protrusion 84 may have a curved surface 84b that curves convexly downward from the upper surface 84a. In this case, the curved surface 84b has an operation surface 85 and a suppression surface 86. The operation surface 85 is within a range in which the touch switch 70 can detect a finger or the like. On the other hand, the suppression surface 86 is a portion other than the operation surface 85 that is located below the operation surface 85.

[0056] Tangent line BB, shown by a thin line in Figure 10, is a tangent line at the lower end of operation surface 85. Therefore, tangent line CC of suppression surface 86, shown by a two-dot chain line in Figure 10, faces downward more than tangent line BB of operation surface 85. Even in such a case, suppression surface 86 faces downward more than operation surface 85, and water W discharged from water outlet 60a can be prevented from adhering to operation surface 85.

[0057] 11, the touch switch 75 may have an operation surface 87 on the upper surface 56 of the protrusion 55. In this case, the operation surface 87 faces upward. Therefore, the suppression surface 58 faces downward relative to the operation surface 87, and therefore, the water W discharged from the water outlet 60a can be prevented from adhering to the operation surface 87.

[0058] FIG. 12 is an explanatory diagram similar to FIG. 5, showing a plumbing device according to a seventh modified example. 13(a) and 13(b) are explanatory diagrams showing a plumbing device according to an eighth modified example. 14(a) and 14(b) are explanatory diagrams showing a plumbing device according to a ninth modified example. 15(a) and 15(b) are explanatory diagrams showing a plumbing device according to a tenth modified example. 12 to 15 show modified examples of a water exposure prevention unit that can be used in place of the water exposure prevention unit 59 described above.

[0059] 12, the water coverage suppression unit 90 may be located above the operation surface 57a and may be a protrusion that protrudes forward. Water W adhering to the upper surface 56 drips rearward from the front end of the water coverage suppression unit 90. This allows the water coverage suppression unit 59 to suppress the water W adhering to the upper surface 56 from flowing from the upper surface 56 toward the operation surface 57a. As a result, it is possible to suppress false detection by the touch switch 70 due to water W adhering to the operation surface 57a.

[0060] As in an eighth modified example shown in FIG. 13, the water exposure prevention portion 91 may be a recess located above the operation surface 57a. The water exposure prevention portion 91 is a recess recessed rearward from the front surface 57. As shown in FIG. 13(b), the water exposure prevention portion 91 extends, for example, to the left-right (widthwise) ends of the front surface 57. This allows water W flowing from the upper surface 56 toward the operation surface 57a to enter the water exposure prevention portion 91 and then drip downward from the end of the water exposure prevention portion 91. As a result, it is possible to prevent water W from adhering to the operation surface 57a and causing erroneous detection by the touch switch 70.

[0061] As in a ninth modified example shown in FIG. 14, the water exposure prevention portion 92 may be a recess located above the operation surface 57a. The water exposure prevention portion 92 is a recess that is recessed downward from the upper surface 56. As shown in FIG. 14(b), the water exposure prevention portion 92 extends, for example, to the left-right (widthwise) ends of the upper surface 56. This allows water W flowing from the upper surface 56 toward the operation surface 57a to enter the water exposure prevention portion 92 and then drip downward from the ends of the water exposure prevention portion 92. As a result, it is possible to prevent water W from adhering to the operation surface 57a and causing erroneous detection by the touch switch 70.

[0062] As in a tenth modified example shown in FIG. 15 , a water contact prevention portion 95 may be provided on the upper surface 94 of the protruding portion 93. The water contact prevention portion 95 is inclined downward from the front end of the upper surface 94 located above the operation surface 57a toward the rear. In this example, the entire upper surface 94 constitutes the water contact prevention portion 95. The rear end side of the water contact prevention portion 95 may be flat. As shown in FIG. 14( b), the inclination of the water contact prevention portion 95 extends to the ends in the left-right direction (width direction), for example. This allows water W to move rearward along the inclination of the water contact prevention portion 95 and then drip downward from the ends of the water contact prevention portion 95. As a result, it is possible to prevent water W from adhering to the operation surface 57a and causing the touch switch 70 to make a false detection.

[0063] In the above-described embodiment, an example was given in which the water discharge unit 60 was provided in the housing 52. However, the present invention is not limited to this, and for example, the water discharge unit may be provided in the washbasin 20 or a wall located below the housing.
