The fifth frame portion 35 is located between a pair of second frame portions 32 and has a horizontal portion 35H that extends in the left-right direction and the front-rear direction behind each second frame portion 32. A circular central opening 35A penetrating in the vertical direction is formed in the central portion of the horizontal portion 35H of the fifth frame portion 35. A pair of elongated holes 35B penetrating in the vertical direction and long in the left-right direction are formed on both sides of the central opening 35A in the horizontal portion 35H of the fifth frame portion 35. A connection socket 81 into which a drain port (not shown) of the cleaning tank 60 is inserted is attached to the central opening 35A (see FIG. 3). The lower end portion of the connection socket 81 is connected to the upstream end portion of the cleaning pipe 80.

[0022] As shown in FIGS. 2 and 7, the first frame portion 31 is above the third frame portion 33 and below the fifth frame portion 35, and both left and right ends thereof are continuous with the respective second frame portions 32. The first frame portion 31 has a vertical portion 31V that extends in the left - right direction and the up - down direction between a pair of second frame portions 32. The front surface of the vertical portion 31V of the first frame portion 31 extends on substantially the same plane as the front surfaces of the respective second frame portions 32. The first frame portion 31 has a through - hole 31A that penetrates in the front - rear direction at the left - right center portion and the up - down center portion of the vertical portion 31V. The inner diameter of the through - hole 31A is larger than the outer diameter of the connection portion between the drain connection pipe 21 and the drain socket 23 and smaller than the maximum width in the diameter direction of the drain socket 23. The connection portion between the drain connection pipe 21 and the drain socket 23 passes through the through - hole 31A. Four split bolts B5 extend forward from the vertical portion 31V of the first frame portion 31 at substantially equal intervals around the through - hole 31A and are arranged in two rows in both the up - down direction and the left - right direction. Each split bolt B5 passes through a through - hole formed in each of the four protruding pieces 23A protruding from the outer peripheral surface of the drain socket 23, and a nut is tightened to sandwich each protruding piece 23A to fix the drain socket 23 in a predetermined position. The drain socket 23 may be fixed in a predetermined position by passing a countersunk head screw through the through - holes formed in the four protruding pieces 23A of the drain socket 23 from the front, inserting a steel spacer behind each protruding piece 23A, and screwing each countersunk head screw into the vertical portion 31V of the first frame portion 31, even without using the four split bolts B5 that extend forward from the vertical portion 31V of the first frame portion 31. A pair of lower toilet fixing bolts B2 extend forward from the vertical portion 31V of the first frame portion 31 at the left - right both ends of the vertical portion 31V and above the up - down center portion.

[0023] The refractory member 40 is made of stainless steel. As shown in FIGS. 2 and 8, the refractory member 40 has a refractory member main body 41 and a pair of connecting pieces 42. The refractory member main body 41 includes upper and lower side surfaces 41T, 41B and left and right side surfaces 41L, 41R, has no front and rear side surfaces, and is in a substantially rectangular parallelepiped shape that is open in the front-rear direction. The upper and lower side surfaces 41T, 41B and the left and right side surfaces 41L, 41R are plate-shaped. The upper side surface 41T has a central portion at the front end side formed lower than its surroundings. Each connecting piece 42 extends outward in the left and right directions from the rear end edges of the left and right side surfaces 41L, 41R above the vertical center of the refractory member main body 41. Each connecting piece 42 is plate-shaped and is in a rectangular shape that is long in the left and right directions. Each connecting piece 42 has a through hole 42A formed therethrough in the front-rear direction at the left and right outer ends. The through holes 42A formed in each connecting piece 42 are each passed through by a pair of toilet bowl lower fixing bolts B2 extending forward from the vertical portion 31V of the first frame portion 31. The refractory member 40 is attached to the first frame portion 31 by tightening nuts from the front to the toilet bowl lower fixing bolts B2 that have passed through the respective through holes 42A.

[0024] The rear edge of the refractory member body 41 is in contact with the front surface of the vertical portion 31V of the first frame portion 31. The refractory member body 41 is attached to the first frame portion 31 so as to cover the drain socket 23. In a state where the refractory member 40 is attached to the first frame portion 31, the front edge of the refractory member body 41 is located forward of the front edge of the drain socket 23 (see FIG. 4). The refractory member body 41 is forward of the first frame portion 31 and covers the drain socket 23 on the side to which the toilet body 10A is connected. Since the front surface of the vertical portion 31V of the first frame portion 31 extends on substantially the same plane as the front surfaces of the second frame portions 32, the refractory member body 41 covers the drain socket 23 on the front side of the connection portion J of each second frame portion 32 and on the side to which the toilet body 10A is connected. In a state where the refractory member 40 is attached to the first frame portion 31, the cross-sectional shape of the refractory member body 41 cut by a plane orthogonal to the central axis direction of the drain socket 23 is rectangular. In a state where the toilet body 10A is connected to the frame 30, as shown in FIGS. 3 and 4, a range of about 3 / 5 in the front-rear direction from the front end of the refractory member body 41 is accommodated in a space 10S that opens to the frame 30 side of the toilet body 10A. This refractory member body 41 covers the drain socket 23 while being placed on the front side of the rear end of the toilet body 10A. The refractory material 22 for connection pipe that covers the drain connection pipe 21, the first frame portion 31, and the refractory member 40 are arranged without gaps in this order.

The lower part of the front edge of each left and right panel 51A is continuous with the rear surfaces of both left and right ends of the lower panel. The interval between the pair of left and right panels 51A is wider than the interval between the pair of second frame portions 32, and each left and right panel 51A is arranged outside the left and right of each second frame portion 32. As shown in FIGS. 9 and 10, two hinges 57 are attached to the front side of the outer surface of each left and right panel 51A at intervals in the vertical direction. As shown in FIGS. 3 and 9, the back panel 51B is a plate shape long in the left-right direction and connects the pair of left and right panels 51A. The left and right end surfaces of the back panel 51B are continuous with the rear end portions of the upper inner surfaces of the respective left and right panels 51A. The back panel 51B is fixed to the wall surface BW at the rear.

[0026] As shown in FIGS. 3 and 9, the lower front panel 52 is arranged in front of the pair of second frame portions 32. The lower front panel 52 corresponds to the panel. In a front view seen from the front, the lower front panel 52 has a shape in which a notch K that spreads downward from the upper edge is formed with respect to a substantially rectangular outer shape. The notch K is composed of a first notch K1 and a second notch K2. The first notch K1 is rectangular and spreads downward from the central portion of the upper edge of the lower front panel 52 in a front view seen from the front. The second notch K2 is rectangular and spreads downward from the central portion of the lower edge of the first notch K1 in a front view seen from the front. The left and right width of the second notch K2 is smaller than the left and right width of the first notch K1. A pair of toilet bowl lower fixing bolts B2 extending forward from the first frame portion 31 are within the first notch K1 and pass near the left and right lower corners of the first notch K1.

[0027] From the lower part at the center of the left and right sides of the first notch K1 to the second notch K2, the fireproof member 40 attached to the first frame part 31 together with the drain socket 23 passes through. In front of the lower front panel 52 and on the side to which the toilet body 10A is connected, the fireproof member 40 covers the drain socket 23. The lower front panel 52 has a pair of first through holes 52A formed on the left and right outer sides of the first notch K1. A pair of upper toilet fixing bolts B1 extending forward from the second frame part 32 pass through the respective first through holes 52A. The lower front panel 52 has a second through hole 52B formed below the second notch K2. A lower fixing bolt B3 extending forward from the third frame part 33 passes through the second through hole 52B.

[0028] As shown in FIGS. 1, 3, and 11, the upper front panel 53 is detachably attached to the cabinet body 51 above the lower front panel 52. The upper front panel 53 is substantially rectangular in a front view seen from the front. The left and right widths of the upper front panel 53 are the same as the left and right widths of the lower front panel 52. The left and right end edges of the upper front panel 53 extend on the extension lines of the left and right end edges of the lower front panel 52. The front surface of the upper front panel 53 extends on the same plane as the front surface of the lower front panel 52.

[0029] As shown in FIGS. 1 and 11, a pair of doors 54 are attached on the left and right sides of the upper front panel 53 and the lower front panel 52 so as to close the space between them and the wall surface SW in the left-right direction. Each door 54 is vertically long and rectangular in a front view seen from the front. Each door 54 is connected to a hinge 57 attached to the outer surface of each left and right panel 51A of the cabinet body 51. Each door 54 is attached so that the left and right outer edge sides open and close around a rotation axis extending along the left and right inner edges. The shelf board 55 is attached at a predetermined height behind each door 54.

[0030] The counter 56 is detachably attached to the upper front panel 53 and the upper sides of the pair of doors 54. The counter 56 is horizontally long rectangular in a plan view seen from above. The front edge of the counter 56 protrudes slightly forward from the front surfaces of the upper front panel 53 and the pair of doors 54. The rear edge of the counter 56 is in contact with the wall surface BW at the rear. Each of the left and right edges of the counter 56 is in contact with the wall surface SW in the left-right direction.

[0031] As shown in FIGS. 3 and 10, the cleaning tank 60 is placed and attached to the horizontal portion 35H of the fifth frame portion 35. The cleaning tank 60 has a drain port protruding downward formed at the central portion of the lower surface, and a pair of bolts (not shown) extend downward from both the left and right sides of the drain port. The drain port of the cleaning tank 60 is inserted into a connection socket 81 attached to the fifth frame portion 35, and with a pair of bolts of the cleaning tank 60 passed through a pair of long holes 35B formed in the fifth frame portion 35 and nuts tightened from below, the cleaning tank 60 is placed and attached to the horizontal portion 35H of the fifth frame portion 35.

[0032] Next, a method for installing the toilet unit 1 in the toilet booth will be described. First, as shown in FIG. 6, the installer connects the drain connection pipe 21 to the wall drain pipe D1 that protrudes forward and is exposed from the wall surface BW at the rear. At this stage, the installer cuts the fireproof material 22 for the connection pipe to fit the drain connection pipe 21.

[0033] Next, as shown in FIG. 7, the constructor fixes the reinforcing wood 70 to the rear wall surface BW and attaches the frame 30 to the toilet booth. Specifically, the constructor installs the frame 30 at a predetermined position, inserts the rear end portions of the pair of support bolts B4 into the respective through holes 34A of the fourth frame portion 34, and fixes the rear end portions of the respective support bolts B4 to the reinforcing wood 70. Then, the front end portions of the respective support bolts B4 are fixed to the fourth frame portion 34 with nuts so that the fourth frame is in a predetermined installed state. Thereafter, the constructor fixes the lower leg portions 32A of each of the second frame portions 32 to the floor surface F to complete the attachment of the frame 30 to the toilet booth. In a state where the frame 30 is attached to the toilet booth, the front end portion of the drain connection pipe 21 protrudes forward from the through hole 31A formed in the vertical portion 31V of the first frame portion 31.

[0034] Next, the constructor fixes the drain socket 23 to the first frame portion 31 while adhesively fixing the drain socket 23 to the upstream end portion of the drain connection pipe 21. Specifically, the constructor cuts the drain connection pipe 21 protruding forward from the through hole 31A of the first frame portion 31 to a predetermined length, and then attaches four split bolts B5 to the first frame portion 31. Then, while adhesively bonding the outer peripheral surface of the front end portion of the drain connection pipe 21 and the inner peripheral surface of the rear end portion of the drain socket 23 with an adhesive, the constructor passes the four split bolts B5 extending forward from the first frame portion 31 through the through holes formed in the four protruding pieces 23A of the drain socket 23 and tightens the nuts to complete the fixing of the drain socket 23 to the first frame portion 31.

[0035] Next, the constructor attaches the cut connection pipe refractory 22 to cover the drain connection pipe 21 located behind the first frame portion 31, and covers the gap with aluminum tape. As a result, the drain connection pipe 21 is not exposed behind the first frame portion 31.

[0036] Next, the constructor attaches a pair of upper toilet fixing bolts B1 to each of the second frame portions 32, attaches a pair of lower toilet fixing bolts B2 to the first frame portion 31, and attaches a lower fixing bolt B3 to the third frame portion 33.

[0037] Next, as shown in FIG. 8, the constructor attaches the fireproof member 40 to the first frame portion 31. Specifically, the constructor passes a pair of lower toilet fixing bolts B2 extending forward from the first frame portion 31 through through holes 42A formed in each connecting piece 42 and tightens nuts from the front to complete the attachment of the fireproof member 40 to the first frame portion 31. The fireproof member 40 covers the drain socket 23 when attached to the first frame portion 31.

[0038] Next, as shown in FIG. 9, the constructor attaches the cabinet body 51 to the toilet booth. Specifically, the constructor installs the cabinet body 51 at a predetermined position with the back plate 51B removed from the cabinet body 51. Then, the constructor fixes the back plate 51B so as to connect the left and right panels 51A of the cabinet body 51 and fixes the back plate 51B to the wall surface BW at the rear to complete the attachment of the cabinet body 51 to the toilet booth. When the cabinet body 51 is attached to the toilet booth, the fireproof member main body 41, the drain socket 23 covered by the fireproof member 40, a pair of upper toilet fixing bolts B1, and a pair of lower toilet fixing bolts B2 protrude forward from the front surface of the lower front panel 52. When the cabinet body 51 is attached to the toilet booth, the front end surface of the lower fixing bolt B3 slightly protrudes forward from the lower front panel 52.

[0039] Next, as shown in FIG. 10, the constructor attaches the toilet body 10A and the cleaning tank 60 to the frame 30. Specifically, the constructor passes a pair of upper toilet fixing bolts B1 protruding from the front surface of the lower front panel 52 through upper through holes 15A formed in the rear wall portion 15 of the toilet body 10A and passes a pair of lower toilet fixing bolts B2 through lower through holes 15B. Then, the constructor tightens nuts from the front to the fixing bolts B1 and B2 protruding into the recess 14A of the side wall portion 14 through the through holes 15A and 15B to complete the attachment of the toilet body 10A to the frame 30. The toilet body 10A attached to the frame 30 is connected and supported by the frame 30 in a state floating from the floor surface F.

[0040] Next, the installer connects the downstream end of the cleaning pipe 80 to the connecting fitting 11B attached to the water supply port 11A of the toilet body 10A attached to the frame 30, and attaches the connection socket 81 to the central opening 35A of the horizontal portion 35H of the fifth frame portion 35, while connecting the upstream end of the cleaning pipe 80 to the lower end of the connection socket 81. Then, while inserting a pair of bolts extending downward from the lower surface of the cleaning tank 60 into the long holes 35B of the fifth frame portion 35, the installer lowers the cleaning tank 60 from above the horizontal surface portion of the fifth frame portion 35 while inserting the drain port of the cleaning tank 60 into the connection socket 81. The installer tightens nuts from below onto the bolts of the cleaning tank 60 protruding downward from the long holes 35B to complete the attachment of the cleaning tank 60 to the fifth frame portion 35. After that, the installer connects a water supply hose (not visible in the drawing) to the cleaning tank 60 attached to the frame 30.

[0041] Next, as shown in FIG. 11, the installer attaches the upper front panel 53, the shelf board 55, the pair of doors 54, and the counter. Finally, the installer attaches the toilet seat device 10B with a local cleaning function onto the toilet body 10A to complete the construction of the toilet unit 1 in the toilet booth.

[0042] <Embodiment 2> As shown in FIG. 12, in the toilet unit 2 of Embodiment 2, the downstream end of the drain pipe 120 is connected to the floor drain pipe D2 protruding upward from the floor surface F and exposed, and the construction procedures such as the method of attaching the fireproof material 122 for the connection pipe to the drain connection pipe 121 are different from those of Embodiment 1. Other configurations and construction methods are the same as those of Embodiment 1, and the same components are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0043] The drain pipe 120 has a drain connection pipe 121, a refractory material 122 for connection, and a drain socket 23. The drain connection pipe 121 has, in a state of being connected to the floor drain pipe D2, a bellows pipe portion 121A extending vertically from the portion connected to the floor drain pipe D2, and a bent pipe portion 121B that is continuous with the upper end portion of the bellows pipe portion 121A, bends approximately 90°, and extends forward. The refractory material 122 for connection covers the drain connection pipe 121 that extends rearward from the first frame portion 31.

[0044] In this toilet unit 2, after the constructor connects the drain connection pipe 121 to the floor drain pipe D2 and before attaching the frame 30 to the toilet booth, the constructor attaches the refractory material 122 for connection so as to cover only the portion of the drain connection pipe 121 that extends vertically from the floor drain pipe D2. Then, the constructor attaches the frame 30 to the toilet booth and fixes the drain socket 23 to the first frame portion 31. At this time, the split bolts B5 are not attached to the first frame portion 31. A countersunk screw is passed through the through holes formed in the four protruding pieces 23A of the drain socket 23 from the front, and a steel spacer is interposed behind each protruding piece 23A, and each countersunk screw is screwed into the vertical portion 31V of the first frame portion 31 to fix the drain socket 23 to the first frame portion. Thereafter, the constructor adhesively fixes the upstream end portion of the bent pipe portion 121B of the drain connection pipe 121 to the drain socket 23 fixed to the first frame portion 31, and then attaches the refractory material 122 for connection so as to cover the horizontally extending portion of the drain connection pipe 121 that is not covered by the refractory material 122 for connection, and covers the gap with aluminum tape.

[0045] As described above, the fireproof member 40 of Embodiments 1 and 2 includes the toilet body 10A, the drain pipes 20 and 120 having a drain socket 23 connected to the drain outlet 12A of the toilet body 10A, and a first frame portion 31 disposed at a portion through which the drain pipes 20 and 120 pass, and a frame 30 that connects the toilet body 10A. The fireproof member 40 is disposed so as to cover the drain socket 23 on the side where the toilet body 10A is connected rather than the first frame portion 31. Since this fireproof member 40 covers the drain socket 23 on the side where the toilet body 10A is connected rather than the first frame portion 31, the fire resistance of the toilet units 1 and 2 provided with this fireproof member 40 can be improved.

[0046] In Embodiments 1 and 2, the frame 30 has a second frame portion 32 having a connecting portion J that connects the toilet body 10A, and the fireproof member 40 covers the drain socket 23 on the side where the toilet body 10A is connected rather than the connecting portion J. Since this fireproof member 40 covers the drain socket 23 in front of the connecting portion J of the first frame portion 31 and the second frame portion 32 and on the side where the toilet body 10A is connected, the fire resistance of the toilet units 1 and 2 provided with this fireproof member 40 can be improved.

[0047] In Embodiments 1 and 2, the toilet units 1 and 2 include a lower front panel 52 disposed between the frame 30 and the toilet body 10A, and the fireproof member 40 covers the drain socket 23 on the side where the toilet body 10A is connected rather than the lower front panel 52. Since this fireproof member 40 covers the drain socket 23 on the side where the toilet body 10A is connected rather than the lower front panel 52, the fire resistance of the toilet units 1 and 2 provided with this fireproof member 40 can be improved.

[0048] In Embodiments 1 and 2, the toilet body 10A forms a space 10S that opens toward the frame 30 around the drain outlet 12A in a state of being connected to the frame 30, and the fireproof member 40 is housed in the space 10S formed in the toilet body 10A in a state of connecting the toilet body 10A to the frame 30. Since this fireproof member 40 is housed in the space 10S formed in the toilet body 10A, the toilet units 1 and 2 provided with this fireproof member 40 can improve fire resistance without increasing in size.

[0049] The fireproof member 40 of Embodiments 1 and 2 is fixed to the frame 30. Since displacement of this fireproof member 40 can be suppressed and the drain socket 23 can be reliably covered, the fire resistance of the toilet units 1 and 2 provided with this fireproof member 40 can be improved.

[0050] The fireproof member 40 of Embodiments 1 and 2 has a rectangular cross-sectional shape when cut by a plane orthogonal to the central axis direction of the drain pipe 20. Since this fireproof member 40 can cover the drain socket 23 well, the fire resistance of the toilet units 1 and 2 provided with this fireproof member 40 can be improved.

[0051] The toilet units 1 and 2 of Embodiments 1 and 2 include a toilet body 10A, drain pipes 20 and 120 having a drain socket 23 connected to the drain outlet 12A of the toilet body 10A, a first frame portion 31 disposed at a portion through which the drain pipes 20 and 120 pass, a frame 30 connecting the toilet body 10A, and a fireproof member 40. Since this toilet unit 1 and 2 covers the drain socket 23 with the fireproof member 40, the fire resistance can be improved.

[0052] In the toilet units 1 and 2 of Embodiments 1 and 2, the downstream end portions of the drain pipes 20 and 120 are connected to either a floor drain pipe D2 exposed on the floor surface F or a wall drain pipe D1 exposed on the wall surface BW. This toilet unit 1 and 2 can be compatible with both floor drainage specifications and wall drainage use.

[0053] The toilet units 1 and 2 of Embodiments 1 and 2 are arranged in the order of a fireproof material 22, 122 for connection pipes covering the drain pipes 20, 120, a first frame portion 31, and a fireproof member 40. The toilet units 1 and 2 can completely cover the drain pipe 20 with the fireproof materials 22, 122 for connection pipes, the first frame portion 31, and the fireproof member 40 without any gaps.

[0054] The construction method of the toilet units 1 and 2 of Embodiments 1 and 2 is to attach the fireproof member 40 to the first frame portion 31 and connect the toilet body 10A to the frame 30 so that the fireproof member 40 is positioned between the toilet body 10A and the first frame portion 31. The toilet units 1 and 2 with improved fire resistance can be easily constructed.

[0055] (1) The present disclosure is not limited to Embodiments 1 and 2 described above and by the drawings. For example, the following embodiments are also included in the technical scope of the present disclosure. In Embodiments 1 and 2, the drain pipes 20, 120 are covered by the fireproof materials 22, 122 for connection pipes and the fireproof member 40. In contrast, as shown in FIG. 13, the entire drain pipe 20 may be covered by a fireproof member 240 of a single member. (2) In Embodiments 1 and 2, the toilet body 10A is connected to the frame 30 after attaching the fireproof member 40 to the first frame portion 31. In contrast, the toilet body 10A may be connected to the frame 30 after attaching the fireproof member 40 to the toilet body 10A. (3) In Embodiments 1 and 2, the cross-sectional shape of the fireproof member 40 cut by a plane perpendicular to the central axis of the drain pipe 20 is rectangular. In contrast, the cross-sectional shape of the fireproof member is not limited to a rectangular shape and may be other shapes as long as the drain socket can be covered by the fireproof member. (4) In Embodiments 1 and 2, a through-hole 31A through which the drain pipe 20 passes is formed in the vertical portion 31V of the first frame portion 31. In contrast, a cutout that opens upward may be formed in the vertical portion of the first frame portion so that the drain pipe passes through this cutout. In this case, the gap formed between the fireproof member and the fireproof material covering the drain connection pipe may be filled with a fireproof material such as rock wool so as to fill the gap, or the gap may be closed with a metal plate. (5) In Embodiments 1 and 2, the toilet body 10A is supported by the frame 30 in a state of floating from the floor surface F. In contrast, the toilet body may be arranged in contact with the floor surface. (6) In Embodiments 1 and 2, the fireproof member 40 is housed in the space 10S that opens rearward and is formed around the drain port 12A of the toilet body 10A. In contrast, such a space may not be formed in the toilet body. In this case, the fireproof member may be housed in the cabinet or may be exposed behind the toilet body.
