The plurality of water dischargers 26 are exposed on the outer surface of the arm 23.

[0015] The base ends 24 of the pair of arms 23 are supported by the lower ends of the left and right outer surfaces of the housing 11. The arms 23 are rotatable about an imaginary axis 27 in the left-right direction between a storage position (see the imaginary line in FIG. 1 and FIGS. 3 and 7) and a use position (see the solid line in FIG. 1 and FIG. 2). In the storage position, the arms 23 are in an upright position with the tips 25 of the arms 23 pointing directly upward and are arranged along the outer surfaces of the housing 11. In the use position, the arms 23 are in a position where the base ends 24 protrude diagonally upward and forward.

[0016] <Installation structure of water discharge device A> As shown in Fig. 6, device body 10 of water discharge device A is attached to wall W of bathroom B using base member 60. Base member 60 is fixed to wall W, and housing 11 of device body 10 is supported by base member 60. As shown in Figs. 1, 3, and 6, housing 11 is configured by assembling front wall member 40 and support plate 43 to main body frame 33. Housing 11 has a bilaterally symmetrical shape.

[0017] The main body frame 33 is a single part made of synthetic resin. As shown in FIGS. 1 to 3, 6, and 7, the main body frame 33 has a rear wall 34, an upper wall 35, a bottom wall 36, a pair of symmetrical side walls 37, and a pair of symmetrical guide walls 38. The upper wall 35 protrudes forward from the upper edge of the rear wall 34. The pair of side walls 37 protrude forward from the side edges of the rear wall 34. The bottom wall 36 protrudes forward from the lower edge of the rear wall 34.

[0018] An accommodation space 39 is formed inside the main body frame 33 and is surrounded by an upper wall portion 35, a side wall portion 37, and a bottom wall portion 36. As shown in FIG. 7, the accommodation space 39 accommodates the shower switch valve 12, the shower water supply pipe 15, the hand shower pipe 16, the body shower pipe 20, and the branch pipe 21. A pair of guide walls 38 extend vertically and protrude rearward from the side edges of the rear wall portion 34. As shown in FIG. 6, a front wall member 40 is disposed so as to close the opening at the front of the accommodation space 39 of the main body frame 33. A mirror 41 is attached to the front surface of the front wall member 40. The mirror 41 constitutes the front surface F of the water discharger A.

[0019] The base ends 24 of a pair of arms 23 are rotatably supported on the lower ends of both the left and right side wall portions 37. The lower ends of the side wall portions 37 support the weight of the arms 23. The upper end of a metal support plate 43 is fixed to the lower end of the rear wall portion 34. The front surface of the support plate 43 faces the storage space 39 below the rear wall portion 34. The rear surface of the support plate 43 is exposed at the rear surface of the main body frame 33. The shower switch valve 12 is fixed to the support plate 43. The shower switch valve 12 and both the left and right arms 23 are relatively heavy components. The lower end of the housing 11 is the part that supports these heavy components.

[0020] As shown in FIGS. 3 and 6, a pair of first fixing portions 45 are formed on the rear wall 34 of the main body frame 33, spaced apart in the up-down direction. The first fixing portions 45 have an elongated shape extending in the left-right direction. The upper first fixing portion 45 is located at the upper end of the rear wall 34. The lower first fixing portion 45 is located in the center of the rear wall 34 in the up-down direction. As shown in FIGS. 3, 8, and 10, the first fixing portion 45 is located rearward of the rear wall 34 and has a hook portion 46 that protrudes downward. A tapered guide surface 47 is formed at the lower end of the front surface of the hook portion 46. The guide surface 47 causes the thickness of the lower end of the hook portion 46 in the front-to-back direction to decrease toward the bottom. Both left and right ends of the hook portion 46 are supported by the rear wall 34 via a pair of overhanging portions 48. An opening 49 is formed in an area of ​​the rear wall 34 forward of the hook portion 46. At the opening 49 , the front surface of the hook portion 46 is exposed forward of the rear wall portion 34 .

[0021] As shown in FIGS. 3 and 7 , a pair of second fixing portions 50 are formed on the support plate 43, which are symmetrical on the left and right sides. The upper ends of both left and right ends of the support plate 43 function as the second fixing portions 50. The second fixing portions 50 are formed with through holes 51 that penetrate the support plate 43 in the front-to-rear direction. A bolt 88 is inserted through the through holes 51. The second fixing portions 50 are located below the lower first fixing portion 45 in the up-down direction, at the lower end of the housing 11. The second fixing portions 50 are located at a position higher than the support position of the arm 23 on the side wall portion 37.

[0022] The support plate 43 is formed with a pair of symmetrical hook holes 52 each consisting of a notch that penetrates the support plate 43 in the front-rear direction. The hook holes 52 have a horizontally long rectangular shape in a front view. The upper edge of the opening edge of the hook holes 52 in the support plate 43 functions as a third fixing portion 53. The third fixing portion 53 is disposed at the lower end of the support plate 43. The third fixing portion 53 is positioned below the second fixing portion 50 in the up-down direction, at the lower end of the housing 11. The third fixing portion 53 is disposed at approximately the same height as the support position (rotation center) of the arm 23 on the side wall portion 37. The pair of third fixing portions 53 are disposed with a gap between them in the left-right direction. In the left-right direction, the pair of third fixing portions 53 are disposed in the area between the pair of second fixing portions 50.

[0023] As shown in FIGS. 3 and 4 , the base member 60 is an integrated component comprising a metal base plate 61, a pair of upper and lower metal brackets 68, and a metal holder 80. The base member 60 has a bilaterally symmetrical shape. As shown in FIG. 4 , the base plate 61 has a flat plate-shaped main body 62 and a pair of bilaterally symmetrical guide ribs 63 protruding forward from both left and right edges of the main body 62. The main body 62 is formed with one positioning hole 64, one elongated hole 65 extending in the left-right direction, and multiple circular mounting holes 66. In the up-down direction, the positioning hole 64 is located at the upper end of the main body 62. In the left-right direction, the positioning hole 64 is located in the center of the main body 62. The elongated hole 65 is located in the left-right center of the plate body and is positioned lower than the positioning hole 64. The multiple mounting holes 66 are located at both left and right edges of the main body 62.

[0024] The brackets 68 are made of plate material extending in the left-right direction. The upper bracket 68 is disposed at the upper end of the plate main body 62. The lower bracket 68 is disposed at the center of the plate main body 62 in the up-down direction. As shown in Figures 8 and 10, the brackets 68 have a curved shape in a side view of the base member 60. Specifically, the bracket 68 is a single part having a plate-shaped support portion 69, a first support portion 70, and a holding portion 74. The plate-shaped support portion 69 is fixed to the front surface of the plate main body 62 by welding or the like.

[0025] The first support portion 70 has an L-shape in side view. The first support portion 70 protrudes diagonally upward and forward from the upper edge of the plate-shaped support portion 69. The first support portion 70 has an extending portion 71 that extends horizontally forward from the upper edge of the plate-shaped support portion 69, and an elastic pressing portion 72 that protrudes diagonally upward and rearward from the front edge of the extending portion 71. The distance in the front-to-rear direction between the front surface of the plate main body portion 62 and the rear surface of the elastic pressing portion 72 is smallest at the upper edge of the elastic pressing portion 72, and is set to be smaller than the thickness dimension in the front-to-rear direction of the hook portion 46 of the first fixing portion 45.

[0026] The holding portion 74 has an L-shape in side view. The holding portion 74 protrudes diagonally upward and forward from the upper edge of the elastic pressing portion 72. The holding portion 74 has a temporary placing portion 75 that protrudes horizontally forward from the upper edge of the elastic pressing portion 72, and a protrusion 76 that protrudes upward from the front edge of the temporary placing portion 75. The first support portion 70 and the holding portion 74 are capable of elastic deformation. The space above the temporary placing portion 75 and behind the protrusion 76 functions as a holding space 77.

[0027] As shown in FIG. 4, the holder 80 is a single component having a plate-shaped fixing portion 81, a pair of symmetrical second support portions 82, and a pair of symmetrical third support portions 85. The rear surface of the plate-shaped fixing portion 81 is fixed to the front surface of the plate main body portion 62 by screws or the like. Rib-shaped protrusions 83 that protrude forward are formed on both left and right side edges of the plate-shaped fixing portion 81. The second support portions 82 extend in the left-right direction from the front end edges of the rib-shaped protrusions 83 in a flat plate shape from the front end edges of the rib-shaped protrusions 83 parallel to the plate main body portion 62. The extending ends of the second support portions 82 are fixed to the front edges of the guide ribs 63 by welding or the like. In the vertical direction, the second support portions 82 are positioned lower than the lower bracket 68. A female screw hole 84 is formed in the second support portions 82.

[0028] The third support portions 85 have a flat plate-like shape that protrudes forward from both the left and right edges of the plate-shaped fixing portion 81. In the up-down direction, the third support portions 85 are positioned lower than the second support portions 82. The third support portions 85 are disposed at the lower end of the housing 11. In the left-right direction, the pair of third support portions 85 are disposed between the pair of second support portions 82. As shown in FIG. 9 , the third support portions 85 have groove portions 86 formed by cutting out the upper edges of the third support portions 85. The lower edges of the groove portions 86 function as positioning portions 87.

[0029] <Installation procedure for the device main body 10> A main bolt (not shown) is driven into the wall W of the bathroom B. The position at which the main bolt is driven is set so that it aligns with the positioning hole 64 of the base member 60, based on the position at which the water discharge device A will be installed. The base member 60 is positioned on the wall W by hooking the positioning hole 64 onto the main bolt. Next, a sub-bolt (not shown) is passed through the elongated hole 65 and driven into the wall W. After this, screws (not shown) that have been passed through the multiple mounting holes 66 of the base member 60 are driven into the wall W. In this way, the base member 60 is fixed to the wall W. The base member 60 has a flat base plate 61, so that the base member 60 can be stably fixed even if the wall W is significantly uneven.

[0030] In the device main body 10, the front wall member 40 of the housing 11 is removed from the main body frame 33. All components other than the front wall member 40 remain attached to the housing 11. When attaching the device main body 10 to the base member 60, the left and right guide wall portions 38 of the device main body 10 are fitted onto the outer surfaces of the left and right guide ribs 63 of the base member 60, thereby aligning the device main body 10 in the left-right direction with respect to the base member 60. Regarding the up-down movement of the device main body 10, as shown in FIG. 10 , the hook portions 46 of the upper and lower first fixing portions 45 are hooked onto the holding portions 74 of the upper and lower brackets 68 by dropping them from above. This temporarily holds the device main body 10 to the base member 60.

[0031] When the device body 10 is held by the holding portion 74, the hook portion 46 is housed in the holding space 77 of the holding portion 74. When the hook portion 46 is placed on the upper surface of the temporary placement portion 75, the device body 10 is positioned in the up-down direction relative to the base member 60. When the hook portion 46 is caught on the protrusion 76 from behind, the device body 10 is prevented from coming off the holding portion 74 in the forward direction. When the device body 10 is held by the holding portion 74, the device body 10 is located in a position forward and above the normal mounting position relative to the base member 60. When the device body 10 is viewed from the front, the protrusion 76 can be seen at the opening 49 of the rear wall portion 34, making it possible to confirm that the device body 10 is being held.

[0032] When the device body 10 is held by the holding portion 74, there is a gap in the front-to-rear direction between the back surface R of the device body 10 and the wall surface W, so when the device body 10 is held on the base member 60, there is no risk of the back surface of the device body 10 interfering with the wall surface W. The second fixing portion 50 and the third fixing portion 53 are located at a distance diagonally upward and forward from the second support portion 82 and the third support portion 85.

[0033] After the device body 10 is held on the base member 60 by the holding portion 74, the device body 10 is pushed rearward, i.e., toward the front surface of the base member 60, thereby moving the device body 10 to the correct mounting position relative to the base member 60. As the device body 10 is pushed, the hook portion 46 slides along the upper surface of the temporary placement portion 75 and moves so as to drop from the rear end of the temporary placement portion 75 (the upper end of the elastic pressing portion 72) into the first support portion 70.

[0034] As the hook portion 46 drops into the first support portion 70, the device main body 10 moves to the correct mounting position. Because the thickness of the hook portion 46 in the front-to-rear direction gradually decreases toward the bottom end, the elastic pressing portion 72 is elastically displaced forward as the hook portion 46 drops into the first support portion 70. As shown in FIG. 8 , with the elastic pressing portion 72 elastically deformed, the hook portion 46 wedges between the elastic pressing portion 72 and the front surface of the plate main body 62, and the first fixing portion 45 is supported by the first support portion 70.

[0035] When the device body 10 is moved to the correct mounting position, as shown in FIG. 9 , the third fixing portion 53 of the support plate 43 enters the groove 86 of the third support portion 85 so as to drop, and the lower edge of the third fixing portion 53 is placed so as to abut against the upper edge of the positioning portion 87 from above. The third fixing portion 53 abuts against the positioning portion 87, and is supported by the third support portion 85. The device body 10 is positioned in the up-down direction by the third support. When the third fixing portion 53 is positioned by the third support portion 85, as shown in FIG. 8 , the hook portion 46 of the first fixing portion 45 does not contact the extension portion 71 of the first support portion 70 and is positioned above the extension portion 71. Because the third fixing portion 53 fits into the groove 86, the device body 10 does not displace forward away from the third support portion 85.

[0036] When the device body 10 is moved to the correct mounting position, the support plate 43 is positioned so as to face the front surface of the second support part 82, and the through hole 51 of the second fixing part 50 is positioned coaxially with the female screw hole 84 of the second support part 82. The position of the through hole 51 can be visually confirmed from the front of the device body 10. When a bolt 88 is inserted into the through hole 51 from the front of the device body 10 and screwed into the female screw hole 84 and tightened, the second fixing part 50 is fixed to the second support part 82. The left and right ends of the lower end of the housing 11 are supported by the pair of left and right second support parts 82.

[0037] As described above, device main body 10 is supported by first support portion 70, second support portion 82, and third support portion 85, and is thereby attached to base member 60 in the correct attachment position. After device main body 10 is attached to base member 60, the front wall portion is assembled to support plate 43. This completes the attachment work of water discharge device A to wall surface W.

[0038] <Effects of the First Embodiment> The water discharger A of this embodiment 1 comprises a base member 60 fixed to the wall surface W of the bathroom B, and a device main body 10 having a water discharger 26. The base member 60 is provided with a first support portion 70, a second support portion 82, and a third support portion 85 for supporting the device main body 10 in the correct installation position. The first support portion 70, the second support portion 82, and the third support portion 85 are different types of support portions that differ from one another in structure and function for supporting the device main body 10. The base member 60 is provided with two holding portions 74 for temporarily holding the device main body 10 in a hooked state.

[0039] When attaching water discharger A to wall W of bathroom B, base member 60 is fixed to wall W. In this state, device body 10 is hooked onto holding portion 74. This allows device body 10 to be temporarily held to base member 60. The position at which device body 10 is held by holding portion 74 is different from the regular mounting position supported by first support portion 70, second support portion 82, and third support portion 85. Next, device body 10 is moved to the regular mounting position and supported in the regular mounting position by first support portion 70, second support portion 82, and third support portion 85. Because device body 10 is heavy when not disassembled, it is not easy to support device body 10 directly on the multiple supports 70, 82, and 85 of base member 60. The water discharge device A of this embodiment 1 is easy to work with because the device main body 10 can be temporarily held by the holding portion 74 of the base member 60 before the device main body 10 is supported in the correct installation position by the multiple support portions 70, 82, and 85.

[0040] The first support portion 70, the second support portion 82, and the third support portion 85 all have the function of restricting the device body 10 from moving forward away from the wall surface W and the base member 60. According to this configuration, the first support portion 70, the second support portion 82, and the third support portion 85 can reliably support the device body 10 so that it does not move away from the base member 60.

[0041] The multiple support portions 70, 82, and 85 include a first support portion 70. The first support portion 70 elastically presses the device body 10 toward the wall surface W. Specifically, the elastic pressing portion 72 of the first support portion 70 elastically presses the hook portion 46 formed on the first fixing portion 45 of the device body 10 against the front surface of the base member 60. This configuration allows the device body 10 to be supported so as not to be separated from the base member 60 without using screws. The multiple support portions 70, 82, and 85 include a second support portion 82. The device body 10 is fixed to the second support portion 82 by a bolt 88, which serves as a fixing device and is a separate member from the second support portion 82. By fixing the second fixing portion 50 to the second support portion 82 using the bolt 88, the device body 10 can be reliably supported on the base member 60. The multiple support portions 70, 82, and 85 include a third support portion 85. The third support part 85 supports the third fixing part 53 of the apparatus body 10 from below and positions it in the up-down direction. The positioning function of the third support part 85 allows the apparatus body 10 to be supported at a predetermined height.

[0042] The holding portion 74 has a protrusion 76 that protrudes upward and forms a holding space 77 between it and the base member 60. With this configuration, when holding the device body 10 on the base member 60, the hook portion 46, which is a part of the device body 10, can be dropped into the holding space 77 from above, which improves workability. The position at which the device body 10 is temporarily held by the holding portion 74 is set further forward on the base member 60 than the regular mounting position supported by the first support portion 70, the second support portion 82, and the third support portion 85. Because the position at which the device body 10 is held by the holding portion 74 is set away from the front surface of the base member 60, it is possible to avoid interference between the device body 10 and the base member 60 or the wall surface W when the device body 10 is temporarily held.

[0043] The holding portion 74 and the first support portion 70 are arranged so as to be connected in the front-rear and up-down directions. Specifically, the first support portion 70 has an L-shaped protrusion from the front surface of the base member 60. The holding portion 74 has an L-shaped extension diagonally upward from the upper end of the first support portion 70. This configuration facilitates the work of moving the device main body 10 from a position where it is temporarily held by the holding portion 74 to a proper installation position where it is supported by the first support portion 70. The holding portion 74 and the first support portion 70 are integrally formed and constitute a single component, the bracket 68. Compared to a case where the holding portion 74 and the first support portion 70 are separate components, the water discharger A of this embodiment 1 requires fewer components. The first support portion 70 has a horizontally elongated shape. This configuration allows the device main body 10 to be stably supported while preventing the device main body 10 from tilting left and right.

[0044] The device main body 10 includes a pair of arms 23 having a water discharge portion 26 and a housing 11 that supports the pair of arms 23. The pair of arms 23 are attached to both left and right outer surfaces of the housing 11. The first support portion 70, the second support portion 82, and the third support portion 85 that support the housing 11 are positioned in a spaced-apart relationship from one another when viewed from the front. The first support portion 70, the second support portion 82, and the third support portion 85 are spaced apart in the vertical direction. The first support portion 70 is positioned above and spaced apart from the second support portion 82. The second support portion 82 is positioned above and spaced apart from the third support portion 82. With this configuration, when a load is applied to only one of the left and right arms 23, the multiple supports 70, 82, and 85 can support the device main body 10 without tilting.

[0045] The pair of arms 23 are supported at the lower end of the housing 11. The first support portion 70 and the second support portion 82 are arranged in a vertically spaced-apart positional relationship. The second support portion 82 is arranged at a spaced-apart position below the first support portion 70. The upper first support portion 70 elastically supports the housing 11 using the elastic pressing portion 72. The lower second support portion 82 secures the housing 11 with a bolt 88. The lower portion of the housing 11, which receives a heavy load from the arms 23, is stably supported relative to the base member 60 by being secured to the second support portion 82 using the bolt 88. The upper portion of the housing 11, which receives a lighter load from the arms 23, can be supported by the elastic force of the first support portion 70. Because the fastening work using the bolt 88 only needs to be performed on the second support portion 82, the water discharger A of this embodiment 1 is easier to work with than a case in which bolting work is performed on both the first support portion 70 and the second support portion 82.

[0046] The pair of arms 23 are rotatable between a storage position where they are arranged along the outer surface of the housing 11, and a usage position where they protrude forward from the housing 11. As shown in FIGS. 1 to 3, the housing 11 has a holding member 89 that holds the arms 23 in the storage position. With this configuration, when the arms 23 are returned to the storage position, the gap between the housing 11 and the arms 23 can be kept uniform.

[0047] In a front view of the device body 10, the base member 60 and the device body 10 form a vertically long rectangle. The multiple support parts 70, 82, 85 are arranged at intervals in the vertical direction. This configuration prevents the upper and lower ends of the device body 10 from separating from the base member 60.

[0048] The base plate 61 of the base member 60 is made of metal and has a flat plate shape. Even if the wall surface W is distorted or has large unevenness, the device main body 10 can be stably supported by fixing the flat base plate 61 to the wall surface W. The high rigidity of the metal base member 60 allows the device main body 10 to be reliably supported.
