The central axes of the upstream section 61A and the downstream section 61B are twisted relative to each other. The middle section 61C that connects the lower end of the upstream section 61A and the rear end of the downstream section 61B has a central axis that is curved three-dimensionally.

The faucet unit 70 is a unit for discharging water into the sink section 50 in a system separate from the flushing tank 60. As shown in Figs. 1 to 4, the faucet unit 70 has a discharge pipe 71, a discharge operation part 72, a faucet body 73, and a vacuum breaker 74. The discharge pipe 71 and the discharge operation part 72 are provided above the opening 50A of the sink section 50 and protrude forward from the piping unit 10. The discharge pipe 71 discharges flushing water in response to the operation of the discharge operation part 72. A hose 71A is connected to the discharge pipe 71. The hose 71A is a flexible metal hose. The discharge pipe 71 is provided so as to be freely pulled out from the piping unit 10 together with the hose 71A. This allows the discharge pipe 71 to discharge flushing water into the sink section 50 in the desired position and direction.

The water discharge operation part 72 is an operating lever for operating the water faucet body 73 in the water faucet unit 70. As shown in FIG. 4, the water faucet body 73 is arranged behind the water discharge operation part 72. The water faucet body 73 mixes the hot water and room temperature water supplied from the electric water heater 80 in response to the operation of the water discharge operation part 72. The mixed water is supplied to the water discharge pipe 71 via the vacuum breaker 74. The vacuum breaker 74 is arranged in the space S1 to the right of the cleaning tank 60 in the space S above the piping unit 10. The vacuum breaker 74 is arranged in a position toward the rear (near the wall surface W) of the space S1. In the space S1, a space in front of the vacuum breaker 74 is provided with nothing placed therein, which is suitable for inserting a hand during construction or maintenance. The upstream end of the hose 71A is connected to the vacuum breaker 74.

As shown in FIG. 1, the electric water heater 80 is placed on the floor surface F via a base plate (not shown) in the space below the piping unit 10. In this embodiment, the electric water heater 80 is stored in the space toward the lower right of the piping unit 10. The electric water heater 80 can be moved to either the left or right position in the space below the piping unit 10 depending on surrounding conditions such as the rising positions of the above-mentioned pipes P1, P2, and P3. The electric water heater 80 is connected to a first water supply pipe P1. The electric water heater 80 supplies two types of water to the faucet body 73: tap water at room temperature supplied from the first water supply pipe P1, and hot water obtained by heating the tap water.

The piping unit 10 will be described in detail. As shown in FIG. 1 to FIG. 3, the piping unit 10 is configured to have a frame 20, a front plate 30, and the like. The frame 20 is disposed in front of the wall surface W. The frame 20 is formed by combining structural materials. Specifically, the frame 20 is configured by combining members such as a horizontal frame member 21, a vertical frame member 22, and an arm member 23. The horizontal frame member 21 is provided at the upper end of the frame 20 and extends in the horizontal direction. The horizontal frame member 21 is detachably attached to the upper front plate 31 of the front plate 30 described later. The vertical frame member 22 is provided to extend downward from both the left and right ends of the horizontal frame member 21. The lower ends of the left and right vertical frame members 22 are fixed to the floor surface F, respectively. The arm member 23 extends rearward from both the left and right ends of the horizontal frame member 21. The rear ends of the left and right arm members 23 are fixed to the tank fixing member 25 described later.

As shown in FIG. 2, the frame 20 is fixed by a floor fixing member 24, a tank fixing member 25 (illustrated as a fixing member), and a wall fixing member 26. The floor fixing member 24 is a substantially L-shaped bracket. The floor fixing member 24 is disposed on the inside of the lower ends of the left and right vertical frame members 22, respectively, and is fixed to the floor surface F and the vertical frame members 22 with screws.

4 to 6, the tank fixing member 25 has a substantially J-shape in side view, including a rear portion 25A, a receiving portion 25B, and a front portion 25C. The tank fixing member 25 is formed by bending a thin metal plate. The tank fixing member 25 is welded and fixed to the rear ends of the left and right arm members 23. The upper end of the rear portion 25A is connected to the lower surfaces of the left and right arm members 23. The lower portion of the rear portion 25A is formed to be narrower in the left-right direction than the upper portion. Specifically, the rear portion 25A is substantially T-shaped in front view, with the upper portion being wider than the lower portion. The upper portion of the rear portion 25A is larger than the left-right width of the cleaning tank 60, and the lower portion is smaller than the left-right width of the cleaning tank 60. The rear portion 25A is in contact with the wall surface W and fixed with a screw. In other words, the tank fixing member 25 not only fixes the cleaning tank 60 to the frame 20, but also functions as a member for fixing the frame 20 to the wall surface W.

A vacuum breaker fixing part 25D (illustrated as a second fixing part) for fixing the vacuum breaker 74 is provided in the upper right part of the rear part 25A. As shown in Figs. 4 to 6, the vacuum breaker fixing part 25D is formed by bending a thin metal plate into a crank shape when viewed from the side. The upper part of the vacuum breaker fixing part 25D is welded to the rear part 25A, and the lower part extends downward at a position away from the front surface of the rear part 25A. The bracket 74A of the vacuum breaker 74 is fixed to the lower part of the vacuum breaker fixing part 25D with screws.

As shown in Figures 4 to 6, the receiving portion 25B is formed to extend forward from the lower end of the back portion 25A. The rear side of the receiving portion 25B is formed to have a width equal to the left-right width of the lower part of the back portion 25A. The front portion of the receiving portion 25B is formed to be wider in the left-right direction than the rear portion. The left-right width of the front portion of the receiving portion 25B is smaller than the left-right width of the cleaning tank 60. In other words, the receiving portion 25B is formed to have a left-right width smaller as a whole than the left-right width of the cleaning tank 60. The front end of the receiving portion 25B is formed to be concavely cut out toward the rear.

The receiving portion 25B functions as a first fixing portion for fixing the cleaning tank 60. The receiving portion 25B places and fixes the cleaning tank 60 on the upper surface. Specifically, as shown in FIG. 6, the receiving portion 25B has three through holes 25E, 25F, and 25G that penetrate in the vertical direction. The through holes 25E, 25F, and 25G are formed in a line in the left-right direction. A cleaning pipe 61 that supplies cleaning water from the cleaning tank 60 to the sink section 50 is inserted into the central through hole 25E. A fixing bolt 62 (see FIG. 4) for fixing the cleaning tank 60 is inserted into the pair of left and right through holes 25F and 25G. Each through hole 25E, 25F, and 25G is formed in an elongated hole shape with the left-right direction as the longitudinal direction, and the fixing position of the cleaning tank 60 in the left-right direction can be adjusted.

As shown in Figs. 4 to 6, the front portion 25C is formed rising upward from the front end of the receiving portion 25B with a dimension equivalent to the dimension in the left-right direction of the front portion of the receiving portion 25B. The front portion 25C, like the receiving portion 25B, has an overall left-right width smaller than the left-right width of the cleaning tank 60. As shown in Fig. 4, the front portion 25C is located forward of the cleaning tank 60 placed on the receiving portion 25B. When the cleaning tank 60 is attached to the receiving portion 25B of the tank fixing member 25, it is disposed between the rear portion 25A and the front portion 25C. As shown in Fig. 6, the front portion 25C has a gate-shaped shape that is flat in the vertical direction as a whole when viewed from the front. Specifically, the front portion 25C is notched at the lower portion with a width equivalent to the notch width of the front end of the receiving portion 25B, and extends in a strip shape across the entire width in the left-right direction at the upper portion.

As shown in Figures 4 to 6, the front surface 25C is provided with a guide member fixing portion 25H and a hose guide fixing portion 25J (each of which is exemplified as a second fixing portion). Since the guide member fixing portion 25H and the hose guide fixing portion 25J are provided on the front surface 25C, it can be said that they are provided inside the left and right ends of the cleaning tank 60 when viewed from the front. The guide member fixing portion 25H fixes the guide member 75. The hose guide fixing portion 25J fixes the hose guide 76. In detail, the guide member fixing portion 25H fixes the guide member 75 behind the water discharge pipe 71. The guide member 75 is a member that guides the hose 71A pulled out along with the water discharge pipe 71 so that it returns to the water receiving tray 77 (see Figure 4) below when it is pushed back. The hose guide fixing portion 25J fixes the hose guide 76 to the left of the guide member 75. The hose guide 76 is a member that regulates changes in the bending state of the hose 71A from the vacuum breaker 74 to the water discharge pipe 71. The guide member 75 and the hose guide 76 are each members associated with the faucet unit 70.

As shown in FIG. 2, the wall fixing member 26 is provided at the vertical middle of the frame 20. The wall fixing member 26 is generally inverted L-shaped when viewed from the side. The wall fixing member 26 is fixed to the wall surface W at the rear surface of the inverted L shape. The wall fixing member 26 is connected at the upper surface on both the left and right ends to the rear ends of the second arm members 23A extending in the front-rear direction. The front ends of the left and right second arm members 23A are each connected to the vertical middle of the vertical frame member 22.

As shown in Figures 1 and 2, the frame 20 has a front lower end member 27 and a side lower end member 28. The front lower end member 27 and the side lower end member 28 are fixed to the front and side of the frame 20, respectively, when the frame 20 is in an installed state. The front lower end member 27 is detachably attached to the front lower end of the frame 20. A lower front plate 33 of the front plate 30, which will be described later, is fixed to the front lower end member 27.

1 and 2, the front plate 30 is disposed in front of the frame 20. The front plate 30 is divided into three members in the vertical direction. Specifically, the front plate 30 is configured to have an upper front plate 31, a middle front plate 32, and a lower front plate 33. The upper front plate 31 is the member disposed at the top. The upper front plate 31 is located in front of the cleaning tank 60 when the cleaning tank 60 is disposed in the frame 20. The upper front plate 31 is detachably attached to the frame 20 by hooking the hook-shaped fixing member 31A from above the horizontal frame member 21. By removing the upper front plate 31, the waste discharge device 1 can access the space S above the piping unit 10 from the front. Only the upper front plate 31 can be removed without removing the middle front plate 32 and the lower front plate 33.

As shown in FIG. 4, a second hose guide 76A is attached to the rear surface of the upper front plate 31. The second hose guide 76A guides the hose 71A in a portion upstream (toward the vacuum breaker 74) of the portion of the hose 71A guided by the hose guide 76 (see FIG. 1). The hose 71A is movably arranged in the space S2 in front of the cleaning tank 60, i.e., in the space between the cleaning tank 60 and the front plate 30, while being guided by the guide member 75, the hose guide 76, and the second hose guide 76A, and extends from the discharge pipe 71 to the vacuum breaker 74.

As shown in Figs. 1 and 2, the middle front plate 32 is disposed below the upper front plate 31, continuing from the lower end of the upper front plate 31. A sink section 50 is attached to the front surface of the middle front plate 32. The sink section 50 is fixed directly to the frame 20 side in a manner that sandwiches the middle front plate 32. As shown in Fig. 1, the sink section 50 is disposed at the center of the middle front plate 32 in the left-right direction. The lower end of the sink section 50 is located lower than the lower end of the middle front plate 32. A water discharge pipe 71 and a water discharge operation unit 72 are attached to the front surface of the upper end of the middle front plate 32, protruding forward. As shown in Figs. 1 and 3, the water discharge pipe 71 and the water discharge operation unit 72 are disposed between both ends of the sink section 50 in the left-right direction. The water discharge pipe 71 is disposed above the center of the left-right direction of the sink section 50.

1 and 2, the lower front plate 33 is disposed below the middle front plate 32, continuing from the lower end of the middle front plate 32. The upper part of the lower front plate 33 is engaged with the rear surface of the middle front plate 32, and the lower part is screwed to the front lower end member 27. When attached to the frame 20, the upper end of the lower front plate 33 is located above the lower end of the sink section 50. When attached to the frame 20, the lower end of the lower front plate 33 is raised above the floor surface F. When attached to the frame 20, the height from the lower end of the lower front plate 33 to the floor surface F is set to be greater than the height from the upper end of the lower front plate 33 to the lower end of the sink section 50. The thickness of the lower front plate 33 is set to be smaller than the thickness of the middle front plate 32. Therefore, when removing the lower front plate 33, interference between the front surface and the rear surface of the sink section 50 is avoided.

The lower front plate 33 can be removed independently without removing the upper front plate 31 and the middle front plate 32. When removing the lower front plate 33, the two set screws 33C are removed, and the lower front plate 33 is moved downward until the upper end of the lower front plate 33 is lower than the lower end of the sink section 50. This allows the lower front plate 33 to be removed without removing the sink section 50. As described above, the first water supply pipe P1, the second water supply pipe P2, and the drain pipe P3 rise from the floor surface F in the space within the frame 20 behind the lower front plate 33. The electric water heater 80 is installed in the space to the right of these pipes P1, P2, and P3. The front plate 30 is divided into three parts in the vertical direction, and only the lower front plate 33 can be removed, so maintenance of the electric water heater 80 and the pipes P1, P2, and P3 can be easily performed.

The piping unit 10 has a top plate 35. The top plate 35 is detachably attached to the upper surface of the frame 20 by a plurality of mounting members 36. In this embodiment, the plurality of mounting members 36 are hook-and-loop fasteners. The top plate 35 can be removed to access the space S inside the piping unit 10 from above. The front-to-rear size of the top plate 35 is greater than the front-to-rear size of the frame 20. Specifically, the rear end 35A of the top plate 35 is in contact with the wall surface W when attached to the frame 20. When attached to the frame 20, the front end 35B of the top plate 35 hangs down at a position forward of the front surface of the front plate 30 and overlaps the upper front surface of the front plate 30.

A side plate 37 is attached to the right side of the frame 20. The left side of the frame 20 is adjacent to another wall surface perpendicular to the wall surface W. The piping unit in the waste discharge device according to the present disclosure may have a side plate attached to at least one of the left and right side surfaces of the frame, or at least one of the left and right side surfaces of the frame may be adjacent to a wall surface.

The action and effect of the waste discharge device 1 configured as above will be explained. The waste discharge device 1 comprises a frame 20, a sink section 50, a cleaning tank 60, and a tank fixing member 25 as a fixing member. The cleaning tank 60 is disposed within the frame 20 and stores cleaning water for cleaning the sink section 50. The tank fixing member 25 has a receiving portion 25B as a first fixing portion for fixing the cleaning tank 60, and a vacuum breaker fixing portion 25D, a guide member fixing portion 25H, and a hose guide fixing portion 25J as second fixing portions.

In this way, the waste discharge device 1 is configured to fix components other than the cleaning tank 60 to the tank fixing member 25 for fixing the cleaning tank 60. Therefore, the waste discharge device 1 does not require separate fixing members for fixing components other than the cleaning tank 60. Therefore, the waste discharge device 1 can have a simplified structure. Since the waste discharge device 1 does not require separate fixing members for fixing components other than the cleaning tank 60, there is no need for space to place such fixing members or space for installation work. This makes it possible to improve space efficiency by making the entire device smaller and arranging additional components in the vacant space.

The waste discharge device 1 is provided with the above-mentioned fixing portions 25D, 25H, and 25J on the tank fixing member 25 for fixing members other than the cleaning tank 60. Therefore, the waste discharge device 1 can be arranged such that other members are concentrated around the cleaning tank 60, further improving space efficiency.

In the waste discharge device 1, the components other than the flushing tank 60 that are fixed to the tank fixing member 25 are components related to the faucet unit 70. Specifically, the vacuum breaker fixing portion 25D, the guide member fixing portion 25H, and the hose guide fixing portion 25J are fixing portions for fixing the vacuum breaker 74, the guide member 75, and the hose guide 76, respectively. In this way, the tank fixing member 25 for fixing the flushing tank 60 fixes the components related to the faucet unit 70 that discharges flushing water to the sink section 50 in a system different from the water supply system from the flushing tank 60, thereby further improving space efficiency.

In the waste discharge device 1, the tank fixing member 25 as a fixing member has a rear portion 25A that is connected to the frame 20, and a receiving portion 25B that is formed extending forward from the rear portion 25A and serves as a first fixing portion on which the cleaning tank 60 is placed and fixed. This allows the cleaning tank 60 to be fixed securely and appropriately.

In the waste discharge device 1, the guide member fixing part 25H and the hose guide fixing part 25J, which are the second fixing parts, are provided in front of the cleaning tank 60 fixed to the receiving part 25B. This allows for effective use of the space S2 in front of the cleaning tank 60 within the space S above the piping unit 10. Specifically, the guide member fixing part 25H and the hose guide fixing part 25J fix the guide member 75 and the hose guide 76, which are members associated with the hose 71A of the faucet unit 70, respectively. This allows the hose 71A to be conveniently routed in the space S2 in front of the cleaning tank 60.

In the waste discharge device 1, the second fixing part, the vacuum breaker fixing part 25D, is provided on the rear part 25A. Therefore, the vacuum breaker 74 can be suitably positioned in front of the vacuum breaker fixing part 25D.

The waste discharge device 1 includes a front plate 30 disposed in front of the frame 20. The front plate 30 is divided into multiple parts in the vertical direction. The upper front plate 31, which is the part of the front plate 30 located in front of the cleaning tank 60, is detachably attached to the frame 20. Therefore, by removing the upper front plate 31, it is possible to easily access the space S above the piping unit 10 behind the upper front plate 31 without removing the sink section 50, the middle front plate 32, etc. As a result, it is easy to perform maintenance of the cleaning tank 60 behind the upper front plate 31 and maintenance of the faucet unit 70 such as the vacuum breaker 74 and the hose 71A.

In the waste discharge device 1, the left-right center of the cleaning tank 60 is positioned to the left of the left-right center of the sink section 50. This makes it possible to conveniently secure space S1 to the right of the cleaning tank 60, which is a space for placing the vacuum breaker 74.

In the waste discharge device 1, the upper front plate 31 is provided so that it can be easily attached and detached, and a space is secured in front of the vacuum breaker 74 where nothing is placed. Therefore, by removing the upper front plate 31, it is possible to insert one's hand into the left side or underside of the cleaning tank 60 from the space in front of the vacuum breaker 74. As a result, construction and maintenance of the cleaning tank 60 can be easily performed.

In the waste discharge device 1, the cleaning tank 60 is positioned close to the rear wall W. This allows an appropriate space S2 to be secured in front of the cleaning tank 60 for handling the hose 71A.

In the waste discharge device 1, the tank fixing member 25 is integrally formed with the fixing parts 25D, 25H, and 25J for the vacuum breaker fixing part 25D, the guide member fixing part 25H, and the hose guide fixing part 25J as the second fixing part, and the receiving part 25B as the first fixing part. Therefore, the fixing parts for the members other than the cleaning tank will not fall off after installation or be forgotten to be installed. As a result, the installation work can be performed more easily and reliably than in the conventional case where the fixing members are provided separately.

In the waste discharge device 1, the top plate 35 is provided so as to be freely attached and detached.
By removing the top plate 35, maintenance work on the cleaning tank 60, vacuum breaker 74, hose 71A, etc. can be easily performed from above the piping unit 10.
