[0003] [Patent Document 1] JP 2013-238048 A Summary of the Invention [Problem to be solved by the invention]

[0004] Wall-hung flush toilets require load-bearing performance at the attachment portion where they are attached to the wall. The flush toilets described above have room for improvement in terms of weight reduction.

[0005] An object of one aspect of the embodiment is to provide a flush toilet that is lightweight while maintaining load-bearing performance. [Means for solving the problem]

[0006] A flush toilet according to one aspect of the embodiment is attached to a wall surface. The flush toilet comprises a bowl portion and a mounting portion. The bowl portion receives waste. The mounting portion is provided between the bowl portion and the wall surface, and mounts the flush toilet to the wall surface via a mounting member. The mounting portion has at least two mounting holes. The thickness of the wall around the mounting hole on the lower side is thinner than the thickness of the wall around the mounting hole on the upper side.

[0007] This ensures that the flush toilet has strength against loads due to moment, due to the thicker portion around the upper mounting hole. This allows the flush toilet to ensure its load-bearing performance. The flush toilet can also be made lighter by making the thickness of the wall around the lower mounting hole thinner than the thickness of the wall around the upper mounting hole. In other words, the flush toilet can be made lighter while maintaining its load-bearing performance. The flush toilet's lighter weight also makes it easier to install the flush toilet on a wall. The lighter weight of the flush toilet also makes it possible to reduce the moment generated in the flush toilet when it is installed on a wall.

[0008] The mounting portion has at least four mounting holes, and at least one of the mounting holes is provided below an imaginary center line of the mounting portion in the up-down direction.

[0009] As a result, the flush toilet is stably attached to the wall surface by the mounting member that is inserted into the mounting hole below the imaginary center line of the mounting portion.

[0010] The flush toilet also comprises a trap portion, a drain socket, and a drain flange portion. The trap portion communicates with the bowl portion so as to discharge waste from the boil portion. The drain socket connects the trap portion to a drain pipe provided on the wall surface. The drain flange portion is provided around the drain socket. The drain flange portion is provided below the imaginary center line.

[0011] This allows the flush toilet to reduce the moment applied to the drain flange.

[0012] The mounting portion further includes a first thick-walled area and a second thick-walled area. The first thick-walled area has a thickness around the mounting hole on the upper side. The second thick-walled area has a thickness around the mounting hole on the lower side. When the mounting portion is viewed from the bowl portion side, the second thick-walled area is wider than the first thick-walled area.

[0013] This allows the flush toilet to be made even lighter.The flush toilet makes it even easier to install the flush toilet on a wall.In addition, when the flush toilet is installed on a wall, the moment generated in the flush toilet can be even smaller.

[0014] The flush toilet also includes a fascia. The fascia connects the trap portion and the mounting portion. The trap portion includes an uprising pipe and a downcomer pipe. The uprising pipe extends obliquely upward from the lower end of the bowl portion toward the wall surface. The downcomer pipe connects the uprising pipe and the drain socket, and extends obliquely downward from the upper end of the uprising pipe toward the drain socket. The fascia is connected to the mounting portion below the downcomer pipe.

[0015] This allows the flush toilet to increase its strength against moments due to the fascia. This allows the flush toilet to improve its load-bearing performance. Also, by connecting the fascia to the second thick area, the flush toilet can improve the strength of the second thick area. Effect of the Invention

[0016] According to one aspect of the embodiment, weight can be reduced while maintaining load-bearing performance. [Brief description of the drawings]

[0024] The rising pipe 5a communicates with the lower end of the bowl portion 3. The rising pipe 5a extends from the lower end of the bowl portion 3 toward the side wall surface, that is, obliquely upward toward the rear.

[0025] The downcomer pipe 5b connects the upcomer pipe 5a and the drain socket 6. The downcomer pipe 5b is connected to the rear end of the upcomer pipe 5a. The downcomer pipe 5b extends obliquely downward from the upper end of the upcomer pipe 5a toward the drain socket 6. The drain trap 5 is provided so that the lower end of the upcomer pipe 5a is lower than the lower end of the downcomer pipe 5b. The drain trap 5 may be provided so that the lower end of the upcomer pipe 5a is higher than the lower end of the downcomer pipe 5b. The drain trap 5 may be provided so that the lower end of the upcomer pipe 5a is at the same height as the lower end of the downcomer pipe 5b.

[0026] The drain socket 6 is connected to the rear end of the downcomer pipe 5b. The drain socket 6 is connected to a drain pipe provided on the wall surface. That is, the drain socket 6 connects the drain trap 5 to the drain pipe. The drain socket 6 is provided below the first imaginary center line L1 of the mounting portion 8 in the up-down direction.

[0027] The drain flange portion 7 is provided around the drain socket 6. The drain flange portion 7 is provided forward of the rear end of the drain socket 6. The drain flange portion 7 is provided below the first imaginary center line L1.

[0028] The mounting part 8 is provided between the bowl portion 3 and the wall surface. The mounting part 8 is provided at the rear end of the toilet body 2. The mounting part 8 mounts the flush toilet 1 to the wall surface via mounting members. The mounting members are, for example, bolts and nuts. At least two mounting holes 10 are provided in the mounting part 8. Specifically, at least four mounting holes 10 are provided in the mounting part 8. Note that three mounting holes 10 may be provided, or five or more mounting holes 10 may be provided. For example, bolts are inserted into the mounting holes 10.

[0029] For example, four mounting holes 10 are provided in the mounting portion 8. The four mounting holes 10 include two first mounting holes 10a and two second mounting holes 10b. Alternatively, the four mounting holes 10 may include three first mounting holes 10a and one second mounting hole 10b.

[0030] The first mounting hole 10a is provided above the first imaginary center line L1. The first mounting holes 10a are provided on both ends in the left-right direction. The first mounting holes 10a are provided on either side of a second imaginary center line L2 of the mounting portion 8 in the left-right direction. The second imaginary center line L2 may be the center line of the drain trap 5 in the left-right direction. The second imaginary center line L2 may be the center line of the toilet body 2 in the left-right direction.

[0031] The second mounting hole 10b is provided below the first mounting hole 10a. The second mounting hole 10b is provided below the first imaginary center line L1. The second mounting holes 10b are provided on both ends in the left-right direction. The second mounting holes 10b are provided on either side of the second imaginary center line L2.

[0032] The mounting portion 8 includes a first thick area A1 having a thickness around the first mounting hole 10a and a second thick area A2 having a thickness around the second mounting hole 10b. The thickness is the thickness of the mounting portion 8 in the front-rear direction (Y-axis direction). The thickness of the second thick area A2 is thinner than the thickness of the first thick area A1. In other words, the thickness around the second mounting hole 10b is thinner than the thickness around the first mounting hole 10a.

[0033] The first thick area A1 is provided on the upper side of the mounting portion 8. The first thick area A1 includes the periphery of the first mounting hole 10a. The first thick area A1 is provided so as to extend in the left-right direction.

[0034] The second thick-walled area A2 is provided below the first thick-walled area A1. The second thick-walled area A2 includes the periphery of the second mounting hole 10b. The second thick-walled area A2 is provided to extend in the left-right direction. When the mounting portion 8 of the mounting portion 8 is viewed from the bowl portion 3 side (front side), the second thick-walled area A2 is wider than the first thick-walled area A1.

[0035] The second thick-walled area A2 is provided up to below the drain trap 5. That is, the mounting portion 8 is provided so that the lower end of the mounting portion 8 is lower than the lower end of the drain trap 5. The lower end of the mounting portion 8 is provided lower than the lower end of the uprising pipe 5a of the drain trap 5 and the lower end of the downcomer pipe 5b of the drain trap 5.

[0036] The fascia 9 connects the drain trap 5 and the mounting portion 8. The fascia 9 is connected to the mounting portion 8 in the second thick area A2 below the downcomer pipe 5b. The fascia 9 is arranged to include the second imaginary center line L2. The fascia 9 is arranged to extend from the mounting portion 8 to the lower end of the upcomer pipe 5a of the drain trap 5. The fascia 9 is connected to the drain trap 5 along the lower end of the drain trap 5. It is noted that a portion of the fascia 9 does not have to be connected to the lower end of the drain trap 5.

[0037] There may be a plurality of headers 9. The headers 9 may be provided so as not to include the second imaginary center line L2. For example, the headers 9 may be provided in a plurality of positions sandwiching the second imaginary center line L2.

[0038] In a wall-hung flush toilet 1, a large load is placed on the periphery of the mounting member inserted into the first mounting hole 10a due to moment. The strength of the flush toilet 1 is ensured by providing a thick first thick area A1 around the first mounting hole 10a. Additionally, the mounting member inserted into the second mounting hole 10b securely fixes the flush toilet 1 to the wall surface.

[0039] The flush toilet 1 is attached to a wall surface. The flush toilet 1 comprises a bowl portion 3 and an attachment portion 8. The bowl portion 3 receives waste. The attachment portion 8 is provided between the bowl portion 3 and the wall surface, and attaches the flush toilet 1 to the wall surface via an attachment member. The attachment portion 8 has at least two attachment holes 10. The thickness of the wall around the second attachment hole 10b on the lower side is thinner than the thickness of the wall around the first attachment hole 10a on the upper side.

[0040] As a result, the flush toilet 1 is able to ensure its strength against moment loads due to the thicker wall thickness around the first mounting hole 10a. As a result, the flush toilet 1 is able to ensure its load-bearing performance. Also, by making the wall thickness around the second mounting hole 10b thinner than the wall thickness around the first mounting hole 10a, the flush toilet 1 can be made lighter. In other words, the flush toilet 1 can be made lighter while maintaining its load-bearing performance.

[0041] Furthermore, the flush toilet 1's light weight makes it easier to attach the flush toilet 1 to a wall surface. Furthermore, the flush toilet 1's light weight makes it possible to reduce the moment generated in the flush toilet 1 when it is attached to a wall surface.

[0042] The mounting portion 8 has at least four mounting holes 10. Of the mounting holes 10, the second mounting hole 10b is provided below a first imaginary center line L1 of the mounting portion 8 in the up-down direction.

[0043] As a result, the flush toilet 1 is stably attached to the wall surface by the mounting member inserted into the second mounting hole 10b.

[0044] The flush toilet 1 comprises a drain trap 5, a drain socket 6, and a drain flange portion 7. The drain trap 5 communicates with the bowl portion 3 so as to discharge waste from the boil portion. The drain socket 6 connects the drain trap 5 to a drain pipe provided on the wall surface. The drain flange portion 7 is provided around the drain socket 6. The drain flange portion 7 is provided below the first imaginary center line L1.

[0045] As a result, the flush toilet 1 can reduce the moment applied to the drain flange portion 7.

[0046] The mounting portion 8 includes a first thick area A1 and a second thick area A2. The first thick area A1 has a thickness around the first mounting hole 10a. The second thick area A2 has a thickness around the second mounting hole 10b. When the mounting portion 8 is viewed from the bowl portion 3 side, the second thick area A2 is wider than the first thick area A1.

[0047] This makes it possible to further reduce the weight of the flush toilet 1. The flush toilet 1 makes it even easier to install the flush toilet 1 on a wall. Additionally, when the flush toilet 1 is installed on a wall, the moment generated in the flush toilet 1 can be further reduced.

[0048] The flush toilet 1 is equipped with a fascia 9. The fascia 9 connects the drain trap 5 and the mounting portion 8. The drain trap 5 is equipped with an ascending pipe 5a and a descending pipe 5b. The ascending pipe 5a extends diagonally upward from the lower end of the bowl portion 3 towards the wall surface side. The descending pipe 5b connects the ascending pipe 5a and the drain socket 6, and extends diagonally downward from the upper end of the ascending pipe 5a towards the drain socket 6. The fascia 9 is connected to the mounting portion 8 below the descending pipe 5b.

[0049] This allows the flush toilet 1 to increase its strength against moments due to the fascia 9. This in turn improves the load-bearing performance of the flush toilet 1. Additionally, by connecting the fascia 9 to the second thick area A2, the flush toilet 1 is able to improve the strength of the second thick area A2.

[0050] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
