Description

[Technical Field]

[0001] The present invention relates to a fixing structure for a wall-hung toilet. [Background technology]

[0002] Wall-hung toilets, which are Western-style toilets that are fixed in a state where they are suspended from the floor, are known. Wall-hung toilets are installed with the toilet body fixed to the rear side of the toilet room so that the toilet body protrudes from the rear side. As a result, the weight of the toilet body is placed on the rear wall, requiring high strength. Therefore, a technology has been proposed in which a support member for the toilet body is placed on the side wall of the toilet room.

[0003] Even if the toilet body is supported only by the side walls, the fixing strength may not be sufficient. In particular, in apartment buildings, there are cases where strong pillars are not installed inside the walls of the toilet room, and it is difficult to maintain strength if the support member is not fixed to the pillar. Because the internal structure of residential walls varies depending on the construction site, there is a demand for a fixing structure that can install a wall-hung toilet with high strength regardless of the construction site.

[0004] To solve these problems, a fixing structure has been proposed that allows wall-hung toilets to be installed with high strength regardless of the construction site (see, for example, Patent Document 1). Such wall-hung toilets have support members extending to the left and right that are fixed to the back wall that supports the toilet body, and by fixing the support members at a high position on the back wall, the load on the back wall is reduced.

[0005] In such wall-hung toilets, it is possible to install a hand basin on top of a cabinet located behind the toilet. However, compared to floor-standing toilets, wall-hung toilets have a support member fixed to the rear wall at a higher position from the floor, meaning the top of the cabinet is higher. Therefore, if the hand basin is installed on top of the cabinet in a wall-hung toilet, as is the case with floor-standing toilets, it will be difficult for short users, especially children, to wash their hands.

[0006] [Patent Document 1] Japanese Patent Publication No. 2022-119156 Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, an object of the present invention is to provide a fixing structure for a wall-hung toilet that maintains high strength and is equipped with a hand washing basin that makes it easy for users to wash their hands. [Means for solving the problem]

[0008] According to a first aspect of the present invention, this problem is solved by a fixing structure for a wall-hung toilet, which includes a cabinet with a top plate attached to the rear wall of a toilet room, a wall-hung toilet attached forward from the cabinet, a cross bar attached to the top plate side of the cabinet and connecting the wall-hung toilet to the rear wall, and a hand wash basin connected directly or indirectly to the cross bar and installed at a position at least partially lower than the top plate.

[0009] This configuration allows part of the washbasin to be installed lower than the countertop without changing the height of the crossbar, which is installed high above the floor. This maintains the high strength of the fixing structure of the wall-hung toilet, and by installing the washbasin at a position that is not too high, it makes it easier for users to wash their hands at the washbasin.

[0010] In addition, in the fixing structure for a wall-hung toilet according to the second aspect of the present invention, the hand wash basin is installed next to the wall-hung toilet.

[0011] With this configuration, workers can remove and maintain the tank by removing the hand washing basin.

[0012] Furthermore, in the fixing structure for a wall-hung toilet according to the third aspect of the present invention, the hand wash basin is installed further back than the wall-hung toilet.

[0013] With this configuration, when a short user reaches for the hand washing basin located at the back, the angle of the arm is not too large, making it easier to wash the hands.

[0014] Furthermore, in the fixing structure for a wall-hung toilet according to the fourth aspect of the present invention, the central horizontal line of the hand wash basin is located at the same position as the upper end of the top plate or lower than that.

[0015] With this configuration, the hand washing basin is positioned at a low position, making it easy for users to wash their hands.

[0016] Furthermore, in the fixing structure for a wall-hung toilet according to a fifth aspect of the present invention, the hand wash basin is held by a holding member attached to the cross rail.

[0017] With this configuration, the hand washing basin can be easily and reliably installed on the holding member.

[0018] In addition, in the fixing structure for a wall-hung toilet according to the sixth aspect of the present invention, the overflow edge of the hand wash basin is positioned above the horizontal rail.

[0019] With this configuration, for example, a hook can be attached to the washbasin at the same height as the overflow edge and hooked onto the top of the crossbar, making it possible to realize a fixing structure for a wall-hung toilet using a simple manufacturing method.In addition, from the perspective of the manufacturing method for the fixing structure for a wall-hung toilet, the washbasin can also be placed on the crossbar.

[0020] Furthermore, the fixing structure for a wall-hung toilet according to a seventh aspect of the present invention comprises a fixing member that fixes the cross bar to the rear wall, and the fixing member has a support plate portion for attaching the hand basin.

[0021] With this configuration, the fixing member that fixes the cross bar to the rear wall increases the strength of the cabinet that supports the wall-mounted toilet, and since the fixing member also has the function of attaching the hand wash basin, there is no need to provide a separate member for attaching the hand wash basin. [Effects of the Invention]

[0022] To provide a fixing structure for a wall-hung toilet equipped with a hand washing basin that allows a user to easily wash their hands while maintaining high strength. [Brief explanation of the drawings]

[0024] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in Fig. 1, a fixing structure 1 for a wall-hung toilet according to this embodiment is installed in a toilet room 100 in, for example, an apartment building. The toilet room 100 is part of a building framework and is a substantially rectangular space, with its longitudinal direction extending along a front-to-rear direction D1 connecting an entrance (not shown) on the front side of the toilet room 100 to a rear wall 101 on the rear side opposite the entrance. In this specification, "front" refers to the entrance side, i.e., the side facing the rear wall 101, and "rear" refers to the rear wall 101 side. The vertical direction D3 is the top-to-bottom direction, and the width direction D2 refers to the horizontal direction connecting the left and right side walls 102 of the toilet room 100.

[0025] The toilet room 100 is configured to include a rear wall 101 at the back side, a pair of side walls 102 on one side and the other side of the rear wall 101 in the width direction D2, a front wall (not shown) on which an entrance door is provided, and a floor surface 103. In apartment buildings, the rear wall 101 and the side walls 102 are often made of gypsum board or the like. As shown in FIG. 2A, studs 104 serving as pillars are arranged inside the rear wall 101 and the side walls 102. As shown in FIGS. 2B and 2C, baseboards 105 are arranged along the floor surface 103 below the rear wall 101 and the side walls 102.

[0026] In the toilet room 100, as shown in Figure 1, a toilet cabinet 3 is provided integrally with the rear wall 101 at the rear side, and a wall-hung toilet 2 is provided so as to protrude forward in a cantilevered manner from the front panel 31 of the cabinet 3. As shown in Figures 1 and 2A, the fixing structure 1 for the wall-hung toilet includes the wall-hung toilet 2, a cross bar 4 as a support member, a rear reinforcing member 5, a side reinforcing member 6, a fixing member 7, and the cabinet 3.

[0027] As shown in FIGS. 2A to 2C, the wall-hung toilet 2 has a toilet body 21, a toilet seat 22, a toilet lid 23, a water supply section 24, a drain pipe 25, and a frame section 26.

[0028] The toilet body 21 is a concave container with an open top, and is installed in a floating state at a position away from the floor surface 103. The toilet body 21 is formed with a drain outlet at the bottom for discharging waste and the like, and the drain outlet is connected to a sewer pipe on the rear side of the toilet body 21 via a drain trap (not shown).

[0029] The toilet seat 22 is placed on top of the toilet body 21 and is a member on which the user sits. The toilet lid 23 is a lid material that covers the upper opening of the toilet body 21. The toilet seat 22 and the toilet lid 23 are each rotatably connected by hinges located on the rear side of the toilet body 21, and are provided so as to be able to be opened and closed.

[0030] As shown in Figure 2B, the water supply unit 24 has a tank 241 and a water supply pipe 242. Water is supplied from an external water source and stored in the tank 241. The flush water stored in the tank 241 is supplied to the toilet body 21 through the water supply pipe 242.

[0031] The drain pipe 25 is connected to a drain outlet provided on the rear side of the toilet body 21. The drain pipe 25 is connected to a sewer pipe inside below the floor surface 103.

[0032] 1, the frame portion 26 connects the rear end side of the toilet body 21 to support the toilet body 21 in a cantilevered state, and also supports the tank 241. The frame portion 26 has vertical bars 261, upper bars 262, lower bars 263, a tank support member 264, and a connecting portion 265.

[0033] A pair of vertical beams 261 are erected on the floor 103 at a predetermined interval in the width direction D2 of the toilet body 21. The upper beam 262 is disposed at the upper end of the pair of vertical beams 261 so as to extend in the width direction D2. The lower beam 263 is disposed below the upper beam 262 at a distance, with one end connected to one vertical beam 261 and the other end connected to the other vertical beam 261. The tank support member 264 is a plate member attached between the pair of vertical beams 261, extending in the width direction D2, between the upper beam 262 and the lower beam 263. As shown in FIG. 2B , the tank support member 264 protrudes rearward from the back surface of the vertical beam 261, and the tank 241 is attached on top of the tank support member 264. The connecting portion 265 is a rod that connects the upper beam 262 and the horizontal beam 4 (described later) and extends in the front-to-rear direction D1.

[0034] The cross rail 4 is placed on the back of the wall-hung toilet 2. The cross rail 4 is placed on the indoor side of the back wall 101, and is one of the components that connect the wall-hung toilet 2 and the back wall 101. The cross rail 4 is composed of a long plate that extends in the width direction D2. The cross rail 4 is connected to the upper cross rail 262 of the frame part 26 via a connecting part 265. The cross rail 4 receives the load of the frame part 26 and the toilet body 21 applied to the frame part 26 via the connecting part 265, and supports the wall-hung toilet 2. Examples of materials for the cross rail 4 include wood and metals such as steel.

[0035] The rear reinforcement 5 is a plate material fixed to the rear wall 101 behind the cross rail 4. As shown in FIG. 2C , the rear reinforcement 5 is composed of a substantially rectangular plate larger than the cross rail 4 and has a planar shape that conforms to the rear wall 101. The upper end of the rear reinforcement 5 is located slightly above the upper ends of the cross rail 4 and the frame portion 26, and the lower end is positioned in contact with the upper end of the baseboard 105. The width of the rear reinforcement 5 corresponds to the length extending from one side of the pair of side walls 102 to the other. The rear reinforcement 5 may be made of wood, for example. The rear reinforcement 5 is connected to the studs 104 with screws where there are studs 104 inside the rear wall, and is connected with plastic plugs or the like where there are no studs 104. By fixing the cross rail 4 to the surface of the rear reinforcement 5, the rear reinforcement 5 reinforces the cross rail 4, and the rear reinforcement 5, together with the cross rail 4, bears the weight of the wall-hung toilet 2.

[0036] The side reinforcement members 6 are plates that extend from both sides of the rear reinforcement member 5 in the width direction D2 toward the sides of the wall-hung toilet 2 and are fixed to the side walls 102. The side reinforcement members 6 have a planar shape that follows the side walls 102. A pair of side reinforcement members 6 are arranged facing each other along the pair of side walls 102. The width of the side reinforcement members 6 is approximately the same as the length of the cabinet 3 (described later) in the front-to-rear direction D1. More specifically, as shown in FIG. 2A, the front end of the side reinforcement member 6 is arranged slightly forward of the front panel 31 of the cabinet 3 (described later). In FIG. 2A, the top plate 32 of the cabinet 3 (described later) is not shown. The upper end of the side reinforcement member 6 is located slightly above the upper ends of the cross rails 4 and the frame portion 26, and the lower end is located in contact with the upper end of the baseboard 105.

[0037] As shown in Figure 2A, the side reinforcement member 6 and the back reinforcement member 5 are arranged in a roughly U-shape that opens forward in a plan view. The side reinforcement member 6 is arranged back-facing so that its rear end is located on the surface of the back reinforcement member 5. The surface of the back reinforcement member 5 is the front surface of the toilet room 100 on the plate surface of the back reinforcement member 5. The side reinforcement member 6 is arranged in contact with the outer end of the back reinforcement member 5 in the width direction D2. By arranging the side reinforcement member 6 back-facing, the rear end of the side reinforcement member 6 supports the back reinforcement member 5 when a load is applied to the back reinforcement member 5 in a direction that causes it to tip forward due to the weight of the wall-hung toilet 2. The side reinforcement member 6 supports the wall-hung toilet 2 on its side.

[0038] The fixing members 7 are metal fittings for fixing the cross beams 4 and the rear reinforcement member 5 to the rear wall 101 and for connecting the rear reinforcement member 5 and the side reinforcement member 6 to the side wall 102. The fixing members 7 include screws, bolts, etc., and fix at least the cross beams 4 and the rear reinforcement member 5 to the rear wall 101. As shown in FIG. 3 , the fixing members 7 have a cross beam connecting portion 70, a rear wall side connecting portion 71, a step portion 72, a corner side connecting portion 73, and a splice portion 74. The fixing members 7 will be described later with reference to FIG. 7 .

[0039] The horizontal rail connection part 70 is formed in a substantially flat plate shape so that it comes into surface contact with the front surface of the horizontal rail 4 and is connected with screws, bolts, etc. A plurality of through holes 70a are formed in the horizontal rail connection part 70 for fastening with screws. The horizontal rail connection part 70 is attached so that the screws pass through the horizontal rail 4 and the rear reinforcement member 5.

[0040] The rear wall connection portion 71 extends outward in the width direction D2 beyond the ends of the cross bars 4 and is formed in a generally flat plate shape. The rear wall connection portion 71 is fixed so as to contact the rear wall 101. A plurality of through holes 71a for screw fastening are formed in the rear wall connection portion 71. The rear wall connection portion 71 is attached so that the screws pass through the rear reinforcement member 5.

[0041] The step portion 72 connects the horizontal rail connection portion 70 and the rear wall connection portion 71. The step portion 72 extends rearward so as to cover the side end portion of the horizontal rail 4, and is formed in a substantially flat plate shape.

[0042] The corner-side connection portion 73 gradually extends forward from the rear wall-side connection portion 71 outward in the width direction D2. In other words, the corner-side connection portion 73 is a generally flat portion that extends diagonally from the rear wall-side connection portion 71. The corner-side connection portion 73 is disposed diagonally with respect to the corner where the rear reinforcement member 5 and the side reinforcement member 6 are connected. If a stud 104 is present inside the corner where the side wall 102 and the rear wall 101 are joined, the corner-side connection portion 73 may be fastened to the stud 104 with a screw.

[0043] The splice plate portion 74 is a portion that extends forward from the corner-side connection portion 73 along the side reinforcement member 6, and has a surface that faces the step portion 72. The splice plate portion 74 is not fastened to the side reinforcement member 6 with screws, but is connected to the side reinforcement member 6 by making surface contact with the side reinforcement member 6, and supports the side reinforcement member 6. The splice plate portion 74 may be fixed to the side wall 102 with a plastic plug or the like.

[0044] The cabinet 3 is a cupboard that houses and conceals the frame 26 of the wall-hung toilet 2, the water supply unit 24 such as the tank 241, and the drain pipe 25. As shown in FIG. 2B, the cabinet 3 has a front panel 31, a top plate 32, connecting side plates 33, and a width adjustment member 34.

[0045] The front panel 31 is a plate member that is disposed on the front surface of the frame portion 26 and extends in the vertical direction. The front panel 31 is disposed between the toilet body 21 and the frame portion 26, and is generally parallel to the rear wall 101. The length of the front panel 31 in the width direction D2 is shorter than the distance between the pair of side walls 102 of the toilet room 100. As shown in FIG. 1, the front panel 31 has an upper front panel 311 and a lower front panel 312. The upper front panel 311 is composed of a single plate member that is disposed on the upper part of the toilet body 21. The lower front panel 312 is divided into three pieces and attached to the rear surface of the toilet body 21. A front panel baseboard 31a is disposed at the lower end of the front panel 31.

[0046] The top plate 32 is a so-called counter, and is a substantially rectangular board located between the upper end of the front panel 31 and the rear wall 101. The top plate 32 is located substantially horizontally between a pair of side reinforcing members 6, except for the portion where the washbasin 50 (described later) is installed, and closes the space between the front panel 31 and the rear wall 101. The top plate 32 is hingedly connected to the cross bars 4 and is attached so that it can be opened and closed by rotating the rear end side. The top plate 32 is located at a height of, for example, 930 mm from the floor surface 103. Therefore, when the washbasin 50 is installed on the top plate 32, the overflow edge 51 of the washbasin 50 is located at a height of, for example, 940 mm. Therefore, the position of this washbasin 50 is generally higher than the position of the washbasin 50 located on the top plate of a cabinet of a floor-standing toilet.

[0047] 2A, the connecting side plate 33 is connected to the end of the front panel 31 on the rear side in the width direction D2 and is attached toward the inner depth of the cabinet 3 so as to be approximately perpendicular to the front panel 31. The connecting side plate 33 is a narrow, vertically elongated plate member having a length in the up-down direction D3 that is approximately the same as that of the width adjustment member 34 described later.

[0048] The width-adjusting member 34 is a vertically elongated plate extending in the up-down direction D3 of the cabinet 3. The width-adjusting member 34 is composed of a plate narrower than the front panel 31 and is disposed on both sides of the front panel 31 in the width direction D2, with a gap between them and the back surface of the front panel 31. The width-adjusting member 34 has a long hole 330 at its upper end that is long in the width direction D2. The width-adjusting member 34 is connected to the rear end of the connecting side panel 33 by inserting a screw through the long hole 330. The width-adjusting member 34 is disposed deep in the gap between the front panel 31 and the pair of side walls 102 when viewed from the front of the toilet room 100, so that the interior of the cabinet 3 is not visible. The distance between the widthwise end of the front panel 31 and the side wall 102 varies depending on the interior dimension of the toilet room 100 in the width direction D2 and the dimension of the front panel 31 in the width direction D2. Therefore, by changing the position of the screw inserted into the long hole 330, the attachment position of the width adjusting member 34 can be changed between the widthwise end of the front panel 31 and the side wall 102. In Figure 2C, the connecting side plate 33 and the width adjusting member 34 are omitted.

[0049] FIG. 4 is a front view of the cabinet 3 having the wall-hung toilet 2. As shown in the figure, the cross bars 4 are installed horizontally inside the cabinet 3 across almost the entire internal space of the cabinet 3, and are not shortened in order to firmly hold the wall-hung toilet 2. The cross bars 4 connect the wall-hung toilet 2 to the rear wall 101. The cross bars 4 are positioned high above the floor 103 (for example, at a height of 830 mm), that is, the cross bars 4 are located on the top of the cabinet 3, on the top panel 32 side of the cabinet 3, away from the wall-hung toilet 2. This maintains the high strength of the wall-hung toilet 2.

[0050] On the other hand, the top plate 32 extends from the left end of the cabinet 3 to the hand basin 50 in the width direction D2. The hand basin 50 is arranged adjacent to the hand basin 50 in the width direction D2. The hand basin 50 is attached to the cross beam 4. Additionally or alternatively, as will be described later, the hand basin 50 may be held by a bracket 55 attached to the support plate portion 74 of the fixing member 7. In this embodiment, a portion of the hand basin 50 is installed at a position lower than the top plate 32 of the cabinet 3 in the up-down direction D3.

[0051] In particular, the central horizontal line of the hand washing basin 50 may be located at a position equal to or lower than the upper end of the top plate 32.

[0052] As shown in the figure, the hand wash basin 50 is installed next to the wall-hung toilet 2. In this embodiment, the left end of the hand wash basin 50 is located above the wall-hung toilet 2, but as shown in Figure 5, which shows a modified example of a cabinet 3 having a wall-hung toilet 2, if sufficient width of the cabinet 3 can be ensured, the hand wash basin 50 may be positioned to the side so as not to overlap vertically with the wall-hung toilet 2. This allows users to approach the hand wash basin 50 while avoiding the wall-hung toilet 2 and wash their hands.

[0053] 4 and 5, the hand wash basin 50 is installed further back than the wall-hung toilet 2. In addition, in the front-to-back direction D1, the front surface of the hand wash basin 50 may coincide with the front surface of the cabinet 3. This allows the hand wash basin 50 to have the same depth as the cabinet 3 in the front-to-back direction D1, creating an integrated appearance of the hand wash basin 50 and the cabinet 3, giving the user the impression that the interior space of the toilet room 100 is neat and tidy.

[0054] However, as shown in Figure 6, which shows a cabinet 3 having a wall-hung toilet 2 according to a further modification, the front surface of the hand wash basin 50 may be positioned forward of the front surface of the cabinet 3 in the front-to-rear direction D1. This brings the hand wash basin 50 closer to the user, so that when the space beside the wall-hung toilet 2 is narrow, the user can reach the hand wash basin 50 without having to step into that space to get closer to the hand wash basin 50.

[0055] 4 to 6, the overflow edge 51 of the hand washing basin 50 is located above the horizontal rail 4.

[0056] FIG. 7 is a schematic perspective view showing the horizontal beam 4 and the fixing member 7 attached to the horizontal beam 4. As shown in FIG. Figure 7(a) shows a conventional fixing member. Depending on the reinforcement conditions of the wall on which the wall-hung toilet 2 is to be installed, it may be necessary to install a fixing member 7 that is fixed to the crosspiece 4. The fixing member 7 is fixed to the end of the crosspiece 4, and may get in the way when installing the hand basin 50. Therefore, it is desirable for the fixing member 7 to also have the function of supporting the hand basin 50.

[0057] FIG. 7(b) shows a fixing member 7 for fixing the cross rail 4 to the rear wall 101 according to an embodiment of the present invention. This fixing member 7 has a support plate portion 74 that extends forward (toward the user) in the front-to-back direction D1 along the side reinforcement member 6 to mount the hand wash basin 50. The support plate portion 74 extends at least the full depth of the hand wash basin 50 in the front-to-back direction D1. Although not shown, an L-shaped bracket 55 (see FIG. 8) is fastened to the support plate portion 74 with screws or bolts, and the bracket 55 holds the bottom surface of the hand wash basin 50. The bracket 55 has a hole 55a for inserting the screw or bolt. Alternatively, the hand wash basin 50 can be installed by hooking a hook (not shown) attached to the outer side of the hand wash basin 50 onto the support plate portion 74. Therefore, as shown in FIG. 7(c), the hand wash basin 50 can be installed using the support plate portion 74.

[0058] FIG. 9 is a schematic perspective view of a fixing structure for a wall-hung toilet according to a further modified example. Figure 9 shows the internal structure of the fixing structure 1 for a wall-hung toilet. In addition to or instead of attaching the bracket 55 or hook to the support plate 74, the bracket 55 (see Figure 8) as a holding member can be fastened to the cross beam 4 with a screw or bolt, or a hook (not shown) can be attached to the back of the washbasin 50. Therefore, by placing the washbasin 50 on this bracket 55 or by hooking the hook onto the support plate 74, the washbasin 50 can be installed as shown.

[0059] <Action and effect> As described above, the fixing structure 1 for the wall-hung toilet in this embodiment comprises a cabinet 3 having a top plate 32 and provided on the rear wall 101 of the toilet room 100, a wall-hung toilet 2 provided forward from the cabinet 3, a cross bar 4 provided on the top plate 32 side of the cabinet 3 and connecting the wall-hung toilet 2 and the rear wall 101, and a hand wash basin 50 directly or indirectly connected to the cross bar 4 and at least partially installed at a position lower than the top plate 32.

[0060] With this configuration, part of the washbasin 50 can be installed at a position lower than the top plate 32 without changing the height position of the crosspiece 4, which is installed at a high position above the floor surface 103. This allows the high strength of the fixing structure of the wall-hung toilet 2 to be maintained, and the washbasin 50 can be installed at a position that is not too high, making it easier for users to wash their hands in the washbasin 50.

[0061] In addition, in the fixing structure 1 for the wall-hung toilet, the hand wash basin 50 is installed next to the wall-hung toilet 2.

[0062] According to this configuration, by removing the hand washing basin 50, an operator can remove the tank 241 and perform maintenance.

[0063] Furthermore, in the fixing structure 1 for the wall-hung toilet, the hand wash basin 50 is installed further back than the wall-hung toilet 2.

[0064] With this configuration, when a short user reaches out to the hand washing basin 50 located at the back, the angle of the arm is not too large, making it easier to wash the hands.

[0065] Furthermore, in the fixing structure 1 for the wall-hung toilet, the central horizontal line of the hand wash basin 50 is located at the same position as the upper end of the top plate 32 or lower than that.

[0066] With this configuration, the hand washing basin 50 is positioned at a low position, allowing the user to wash their hands easily.

[0067] In addition, in the fixing structure 1 for the wall-hung toilet, the hand wash basin 50 is held by a holding member attached to the cross rail 4.

[0068] With this configuration, the hand washing basin 50 can be easily and reliably installed on the holding member.

[0069] In addition, in the fixing structure 1 for the wall-hung toilet, the overflow edge 51 of the hand wash basin 50 is located above the cross rail 4.

[0070] With this configuration, for example, a hook (not shown) can be attached to the washbasin 50 at the same height as the overflow edge 51, and the hook can be hung on the top of the cross rail 4, making it possible to realize the fixing structure 1 for the wall-hung toilet using a simple manufacturing method. Also, from the perspective of the manufacturing method for the fixing structure 1 for the wall-hung toilet, the washbasin 50 can also be placed on the cross rail 4.

[0071] Furthermore, the fixing structure 1 for the wall-hung toilet has a fixing member 7 that fixes the cross rail 4 to the rear wall 101, and the fixing member 7 has a support plate portion 74 for attaching the hand basin 50.

[0072] According to this configuration, the fixing member 7 that fixes the cross bar 4 to the rear wall 101 increases the strength of the cabinet 3 that supports the wall-hung toilet 2, and since the fixing member 7 also has the function of attaching the hand wash basin 50, there is no need to provide a separate member for attaching the hand wash basin 50.
