DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] As shown in Fig. 1, the toilet apparatus 10 is a flush toilet. The toilet apparatus 10 is fixed to a floor surface when in use. The toilet apparatus 10 may be, for example, a so-called wall-hung flush toilet that is fixed to a wall.

[0008] The toilet device 10 comprises a toilet portion 12, a toilet seat 14, a functional portion 16, a tank 18 (see FIG. 2), a discharge portion 40, covers 80, 82, 84 (see FIG. 6), a control portion 100, and a seating sensor 90. FIG. 2 shows a cross-sectional view perpendicular to the left-right direction at the center of the left-right direction of the toilet bowl 22. As shown in FIG. 2, the toilet portion 12 comprises a toilet body 20 and an upper end flange portion 30. The toilet body 20 is made of ceramic. The toilet body 20 comprises a toilet bowl 22 that receives waste. The toilet body 20 accommodates a tank 18 at the lower end of the toilet body 20. The tank 18 stores flushing water for flushing the toilet bowl 22. The toilet device 10 comprises a flush button (not shown) that is electrically connected to the discharge portion 40. When the flush button is operated by the user, flush water is discharged from the tank 18 through the discharge unit 40 into the toilet bowl 22. The functional unit 16 may have functions such as an opening and closing function that automatically opens and closes the toilet lid (not shown) in accordance with the user's actions, a local washing function, a hot air drying function, a deodorizing function, etc.

[0009] In the toilet apparatus 10, flush water in the tank 18 may be supplied to the toilet bowl 22 by operating a lever arranged on the toilet apparatus 10, in addition to operating a flush button. The flush button may be arranged on a remote controller that is electrically connected to the discharge portion 40 either wired or wirelessly. Flush water in the tank 18 may be supplied to the toilet bowl 22 even without operation by the user. For example, flush water in the tank 18 may be supplied to the toilet bowl 22 when the user is not detected by the sensor.

[0010] The toilet seat 14 is attached to the toilet body 20 so as to be openable and closable via a functional part 16. A user sits on the toilet seat 14. The toilet seat 14 has an opening 14a.

[0011] Hereinafter, the direction in which the toilet seat 14 and the functional unit 16 are arranged is referred to as the front-rear direction. In the front-rear direction, the side on which the toilet seat 14 is arranged with respect to the functional unit 16 is referred to as the front side of the front-rear direction, and the opposite side is referred to as the rear side. The horizontal direction perpendicular to the front-rear direction is referred to as the left-right direction. In the left-right direction, the rear side of the paper in FIG. 1 is referred to as the right side, and the front side of the paper in FIG. 1 is referred to as the left side. The left and right directions correspond to the left and right as seen by a user facing the toilet device 10. The vertical direction perpendicular to the front-rear direction is referred to as the up-down direction. In the up-down direction, the side on which the tank 18 is arranged with respect to the toilet body 20 in FIG. 2 is referred to as the lower side, and the opposite side is referred to as the upper side.

[0012] As shown in Figure 2, the toilet bowl 22 has a shape that is generally recessed downward. The toilet body 20 comprises a water storage section 24 that is disposed at the lower end of the toilet bowl 22, a drain pipe 36 that communicates with the water storage section 24, and a drain outlet 34 that opens into the water storage section 24. The water storage section 24 is part of the toilet bowl 22. Water is stored in the water storage section 24 up to the water surface WS. The water surface WS coincides with the curved position 36a of the drain pipe 36. In other words, when flush water is not being supplied to the toilet bowl 22, the area below the water surface WS is referred to as the water storage section 24.

[0013] The water storage section 24 communicates with a drain pipe 36 through a drain outlet 34. The drain outlet 34 is an inlet through which flush water flows from the water storage section 24 to the drain pipe 36. The drain pipe 36 extends upward from the drain outlet 34. The drain pipe 36 bends downward at a curved position 36a and extends downward. The drain pipe 36 extends to the outside of the toilet bowl section 12.

[0014] An upper end flange portion 30 is disposed at the upper end of the toilet bowl 22, encircling the upper end edge 22a of the toilet bowl 22. The upper end flange portion 30 is disposed at the upper end of the toilet body 20. The upper end flange portion 30 protrudes inward from the upper end edge 22a so as to face the surface of the toilet bowl 22. The lower surface 30a of the upper end flange portion 30 is disposed vertically in the up-down direction.

[0015] The toilet bowl 22 has a front surface 23, a side surface 26, and a rear surface 25 in an area above the water collecting portion 24. The front surface 23 is a surface located in front of the front edge WS1 of the water surface WS. The side surface 26 is a surface that extends from the rear edge of the front surface 23 to the rear along both the left and right ends of the water surface WS. The side surface 26 extends to the rear edge of the water surface WS. The rear surface 25 is a surface that extends along the rear edge WS2 of the water surface WS between the rear edges of the side surfaces 26 on both the left and right sides.

[0016] (Configuration of Discharge Section 40) Discharge unit 40 discharges flush water in tank 18 into toilet bowl 22. As shown in Fig. 3, discharge unit 40 includes pump 42, connecting pipe 44, switching valve 46, branch pipes 48a, 48b, 48c, 48d, discharge nozzles 50 and 52, a discharge opening 54, and foam discharge unit 61. Foam discharge unit 61 discharges foam generated by mixing a surfactant and water into toilet bowl 22.

[0017] The pump 42 draws in flush water in the tank 18 and pressurizes it. The pump 42 sends the pressurized flush water to a communicating pipe 44. The communicating pipe 44 is connected to the pump 42. The communicating pipe 44 defines a flow path through which the flush water flows. The communicating pipe 44 is connected to a switching valve 46. The switching valve 46 connects the communicating pipe 44 to at least one of the branch pipes 48a, 48b, 48c, and 48d. A discharge nozzle 50 is connected to the branch pipe 48a. When the communicating pipe 44 is connected to the branch pipe 48a via the switching valve 46, flush water is discharged from the discharge nozzle 50 into the toilet bowl 22. A discharge member 60 of a foam discharge section 61 is connected to the branch pipe 48b. When the communicating pipe 44 is connected to the branch pipe 48b via the changeover valve 46, flush water is discharged from the discharge member 60 into the toilet bowl 22. A discharge nozzle 52 is connected to the branch pipe 48c. When the communicating pipe 44 is connected to the branch pipe 48c via the changeover valve 46, flush water is discharged from the discharge nozzle 52 into the toilet bowl 22. A discharge opening 54 is connected to the branch pipe 48d. When the communicating pipe 44 is connected to the branch pipe 48d via the changeover valve 46, flush water is discharged from the discharge opening 54 into the toilet bowl 22.

[0018] 4, the discharge nozzles 50, 52 and the discharge member 60 are arranged side by side in the left-right direction. The discharge nozzle 50 is arranged near the upper end of the toilet bowl 22. The discharge nozzle 52 is arranged symmetrically with the discharge nozzle 50.

[0019] As shown in Fig. 2, the discharge opening 54 opens into the water storage section 24. The discharge opening 54 opens from the front side towards the drain outlet 34 on the rear side. When flush water is discharged from the discharge opening 54, the flush water in the water storage section 24 is drained into the drain pipe 36 together with the flush water from the discharge opening 54. Waste in the water storage section 24 and any objects floating in the water in the water storage section 24 are also discharged from the drain pipe 36 to the outside of the toilet body 20.

[0020] 3, the foam discharge unit 61 includes a switching valve 62, an ejector 64, supply pipes 65 and 66, a discharge member 60, and a storage tank 68. The ejector 64 is in communication with the pump 42 via a supply pipe 65. A switching valve 62 is disposed in the supply pipe 65. The switching valve 62 switches between a state in which the pump 42 and the ejector 64 are in communication with each other via the supply pipe 65, and a state in which the supply pipe 65 is cut off to cut off the pump 42 and the ejector 64.

[0021] A storage tank 68 is connected to the ejector 64. A surfactant such as detergent is stored in the storage tank 68. A communication pipe 68a extending from the storage tank 68 communicates with the ejector 64. An air vent pipe 69 (see FIG. 6) communicates with the ejector 64. The air vent pipe 69 communicates with the atmosphere. The ejector 64 generates negative pressure in the ejector 64 by reducing the flow path cross-sectional area of ​​the flushing water supplied from the supply pipe 65. The negative pressure generated in the ejector 64 draws the surfactant and air into the ejector 64. As a result, the flushing water, the surfactant, and the air are mixed, and foam is generated. A supply pipe 66 that communicates the ejector 64 with the discharge member 60 is connected to the downstream side of the ejector 64. The foam generated in the ejector 64 passes through the supply pipe 66 and is discharged from the discharge member 60 into the toilet bowl 22. The supply pipe 66 merges with the branch pipe 48b downstream of the ejector 64. A check valve is disposed at the downstream end of the ejector 64 to prevent the cleaning water from flowing back from the branch pipe 48b to the ejector 64.

[0022] Figures 5 and 6 show the configuration of each part of the discharge part 40. All parts of the discharge part 40, except for the branch pipe 48d and the discharge opening 54, are housed in the toilet body 20 at the rear side of the toilet bowl 22. In the toilet body 20, each part of the discharge part 40 is housed in a small space. In each of Figures 5 and 6, some of the configuration has been simplified to prioritize ease of viewing.

[0023] As shown in FIG. 6, the toilet body 20 has an opening 20a, an opening 20b, and an opening 20c on the upper end surface 20d. The upper end surface 20d is arranged horizontally. The opening 20a is located on the left side of the toilet body 20. The opening 20a extends vertically in the toilet body 20. The opening 20a is arranged horizontally. The opening 20a opens upward on the upper end surface 20d and has a rectangular shape surrounded on the front, back, right, and left sides. In a modified example, the opening 20a may be arranged on a surface that is inclined with respect to the horizontal. In another modified example, the opening 20a may be arranged on the left side surface of the toilet body 20. In this case, the opening 20a may face leftward. The opening 20c is located on the right side of the toilet body 20. The opening 20b is located between the openings 20a and 20c. Similar to the opening 20a, the openings 20b and 20c open upward at the upper end surface 20d.

[0024] FIG. 7 shows a perspective view of the toilet body 20 alone from above and in the depth thereof to show the configuration of the openings 20a, 20b, and 20c. In the toilet body 20, a storage space 70 for storing the discharge nozzle 50 is formed below the opening 20a. The discharge nozzle 50 is disposed in the storage space 70 (see FIG. 6). The opening 20c is disposed symmetrically with the opening 20a. In the toilet body 20, a storage space 72 for storing the discharge nozzle 52 is formed below the opening 20c. The discharge nozzle 52 is disposed in the storage space 72. The front, right, and left of the opening 20b are defined by the toilet body 20. The back side of the opening 20b is not surrounded and is open. The openings 20a and 20c are formed in a hole shape. The opening 20b is formed in a notch shape. The opening 20b is open in the vertical direction as well as in the depth direction. Below the opening 20b, a space 76 is formed in which a part of the discharge member 60 and a part of the supply pipe 66 are disposed. The space 76 is a part of a piping space in which the piping of the discharge part 40 and the like are disposed.

[0025] (Configuration of the discharge nozzle) FIG. 8 shows a plan view of the discharge nozzle 50. In FIG. 8, a horizontal (i.e., vertical to the up-down direction) cross section of the toilet body 20 slightly above the upper end of the discharge nozzle 50 is shown to show the configuration of the toilet body 20 around the discharge nozzle 50. As shown in FIG. 8, the discharge nozzle 50 is accommodated in an accommodation space 70. The discharge nozzle 50 is arranged in the accommodation space 70 along the front-rear direction. The accommodation space 70 is defined by an accommodation wall 74 arranged in the toilet body 20. The accommodation wall 74 includes an outer wall 74a, an inner wall 74b, a front side wall 74c, a rear side wall 74d, a lower side wall 74e, and an upper side wall 74f (see FIG. 9). The outer wall 74a is arranged outside the toilet body 20, i.e., on the left side, of the discharge nozzle 50. The outer wall 74a is connected to a wall that constitutes the outer surface of the toilet body 20. The surface of the outer wall 74a facing the storage space 70 is inclined downward to the right in the vertical direction. The surface of the outer wall 74a facing the storage space 70 is connected to the left side surface 26 of the toilet bowl 22. The inner wall 74b is positioned inside the toilet body 20, i.e., on the right side, of the discharge nozzle 50. A branch pipe 48b that supplies flushing water to the discharge member 60 and the like are positioned in the piping space.

[0026] A rear wall 74d is disposed between the rear edge of the outer wall 74a and the rear edge of the inner wall 74b. The rear wall 74d separates the storage space 70 from the piping space. FIG. 9 shows a plan view of the discharge nozzle 50. In FIG. 9, a cross section of the toilet body 20 taken along line IX-IX in FIG. 8 is shown to show the configuration of the toilet body 20 around the discharge nozzle 50. As shown in FIG. 9, the rear wall 74d has a mounting hole 20e. The mounting hole 20e penetrates the rear wall 74d. The communication member 45 penetrates the rear wall 74d through the mounting hole 20e. The discharge nozzle 50 is attached to the mounting hole 20e of the rear wall 74d by the communication member 45. The discharge nozzle 50 is connected to the branch pipe 48a located at the rear of the rear wall 74d via the communication member 45. In other words, the front end of the branch pipe 48a is attached to the rear side wall 74d by the communicating member 45. The branch pipe 48a is connected to the rear end of the communicating member 45. The opening of the mounting hole 20e has a circular shape. This makes it easier to achieve a watertight seal between the mounting hole 20e and the communicating member 45 compared to when the mounting hole 20e has an irregular shape. In a modified example, the mounting hole 20e may have a polygonal shape, such as a square shape.

[0027] A front side wall 74c is disposed on the front edge of the inner wall 74b, and extends toward the front edge of the outer wall 74a. The front side wall 74c is disposed at a distance from the outer wall 74a. The front surface of the front side wall 74c forms part of the rear surface 25 of the toilet bowl 22. The lower end of the storage space 70 is closed by a lower side wall 74e. An upper side wall 74f is disposed at the upper end of the storage space 70. The upper side wall 74f forms an opening 20a. The opening 20a has a rectangular shape. In a modified example, the opening shape of the opening 20a may be a circular shape that is not a perfect circle, such as an elliptical shape.

[0028] The opening 20a is configured to allow the discharge nozzle 50 to pass through. The opening 20a has a shape that accommodates the outer shape of the discharge nozzle 50 when viewed from above in a state in which the discharge nozzle 50 is tilted from the position in which it is attached to the toilet body 20. In a modified example, the opening 20a may have a shape that accommodates the outer shape of the discharge nozzle 50 when viewed from above in a position in which the discharge nozzle 50 is attached to the toilet body 20.

[0029] The discharge nozzle 50 has a tubular portion 56 and a nozzle portion 58 connected to the downstream end of the tubular portion 56. The upstream end of the tubular portion 56 is connected to the branch pipe 48a via the communication member 45. The tubular portion 56 has a cylindrical shape. The tubular portion 56 has a substantially uniform outer diameter over its entirety. The tubular portion 56 has a substantially uniform inner diameter over its entirety. The nozzle portion 58 has an outlet 58a at its downstream end. The discharge nozzle 50 discharges the cleaning water supplied from the branch pipe 48a at the outlet 58a. The outlet 58a has a substantially elongated rectangular shape. The upper and lower edges of the outlet 58a in the short direction are curved. The nozzle portion 58 is arranged along the inclination of the outer wall 74a. The nozzle portion 58 has a plurality of protrusions 58b arranged on its outer surface. The plurality of protrusions 58b contact the surface on the side of the storage space 70. The nozzle portion 58 is fixed and disposed in the accommodation space 70 by the protrusion 58b of the nozzle portion 58. The longitudinal direction of the discharge port 58a is inclined downward and to the right with respect to the vertical direction. The longitudinal length L1 of the discharge port 58a is longer than the lateral length W1 perpendicular to the longitudinal direction. At the downstream end of the nozzle portion 58, the longitudinal length L2 of the discharge port 58a is greater than the opening diameter D1 of the mounting hole 20e. The opening diameter D1 of the mounting hole 20e is greater than the outer diameter D2 of the cylindrical portion 56. In a modified example, the discharge port 58a of the nozzle portion 58 does not have to be elongated. The length of the discharge port 58a in a first direction (e.g., the vertical direction) may be substantially equal to the length in a second direction (e.g., the left-right direction) perpendicular to the first direction.

[0030] 10 shows a cross section perpendicular to the up-down direction directly below the underside 30a of the upper end flange portion 30 of the toilet body 20. The discharge nozzle 50 is housed in the accommodation space 70 of the toilet body 20. A water outlet 70a is disposed in the toilet body 20 on the front side of the discharge nozzle 50. The water outlet 70a is disposed at the front end of the accommodation space 70. The water outlet 70a has an opening area larger than the opening area of ​​the discharge outlet 58a of the discharge nozzle 50 (see FIG. 4). The flushing water discharged from the discharge nozzle 50 is supplied to the toilet bowl 22 from the water outlet 70a.

[0031] The discharge nozzle 52 is configured in the same manner as the discharge nozzle 52. The discharge nozzle 52 is accommodated in an accommodation space 72 formed in the same manner as the accommodation space 70. The toilet body 20 has a mounting hole 20g formed in the rear wall that defines a part of the accommodation space 72. The discharge nozzle 52 is attached to the mounting hole 20g. The accommodation space 72 has a water outlet 72a similar to that of the accommodation space 70.

[0032] (Configuration of Discharge Member) Discharge member 60 is disposed on the rear side of water outlets 70a, 72a. Foam discharged from discharge member 60 can be discharged from the rear side of water outlets 70a, 72a onto toilet bowl 22. This allows the foam to clean rear surface 25 of toilet bowl 22.

[0033] The discharge member 60 and a portion of the supply pipe 66 are accommodated in the space 76. The space 76 is defined by a partition wall 78 arranged in the toilet body 20. The partition wall 78 includes a left side wall 78a, a right side wall 78b, and a front side wall 78c. The left side wall 78a is located on the left side of the discharge member 60. The left side wall 78a is connected to the inner side wall 74b of the storage space 70. The connected left side wall 78a and the inner side wall 74b separate the space 76 from the storage space 70. The left side wall 78a and the inner side wall 74b may be made as an integral wall. The right side wall 78b is located on the right side of the discharge member 60. The right side wall 78b is connected to the inner side wall arranged inside the storage space 72. The right side wall 78b is connected to the inner side wall of the storage space 72. The left side wall 78a and the inner side wall 74b connected to each other separate the space 76 from the storage space 72. The right side wall 78b and the inner side wall of the storage space 72 may be fabricated as a single wall.

[0034] A front side wall 78c is disposed between the front edge of the left side wall 78a and the front edge of the right side wall 78b. The front side wall 78c is connected to the front side wall 74c of the storage space 70. The front side wall 78c and the front side wall 74c may be fabricated as an integral wall. The front surface of the front side wall 78c forms a part of the back surface 25 of the toilet bowl 22. The front side wall 78c has a mounting hole 20f. The mounting hole 20f penetrates the front side wall 78c. The opening of the mounting hole 20f has a circular shape. The discharge member 60 is inserted into the mounting hole 20f of the front side wall 78c. The discharge member 60 has a thread that engages with the nut 60x. The discharge member 60 is fixed to the toilet bowl 22 by sandwiching the toilet bowl 22 together with the nut 60x. The downstream end of the discharge member 60 has a discharge port 60f. The discharge port 60f opens upward in the upper surface 60a of the discharge member 60. A supply pipe 66 is connected to the upstream end of the discharge member 60.

[0035] (Cover composition) As shown in FIG. 6, covers 80, 82, and 84 are arranged on the openings 20a, 20b, and 20c provided on the toilet body 20, respectively. The cover 80 has a flat plate shape. The cover 80 entirely covers the opening 20a. The interior of the opening 20a cannot be seen, improving the design. The cover 80 is made of resin. As shown in FIG. 15, the cover 80 is fixed to the upper end surface 20d of the toilet body 20 by an adhesive tape 88. Fine alignment of the cover 80 is not required. This makes it easy to attach the cover 80 to the toilet body 20. In a modified example, the cover 80 may be fixed to the toilet body 20 by a fastener such as a bolt. A seal member 86 is arranged on the cover 80 at the periphery of the back surface, extending all the way around the periphery of the cover 80. The cover 80 can watertightly cover the opening 20a. This can prevent flush water supplied to the discharge nozzle 50 from leaking out of the toilet body 20 through the opening 20a. The seal member 86 is a viscoelastic member such as a rubber member. In a modified example, the cover 80 does not need to be provided with the seal member 86 for watertightly closing the opening 20a. In this case, the cover 80 may be made of a viscoelastic member such as a rubber member, and may watertightly close the opening 20a. The covers 82 and 84 are configured in the same manner as the cover 80. The cover 82 closes the opening 20b, and the cover 84 closes the opening 20c.

[0036] (Functional Part Configuration) 12 to 14, the functional part 16 is disposed on the toilet body 20. The functional part 16 is disposed so as to entirely cover the covers 80, 82, and 84. That is, the functional part 16 covers the openings 20a, 20b, and 20c.

[0037] As shown in FIG. 13, the functional unit 16 includes a functional unit main body 16a, a base plate 16b, and a moving device 16c. The base plate 16b is attached to the upper end surface 20d of the toilet body 20. The base plate 16b entirely covers the openings 20a, 20b, and 20c. In a modified example, the base plate 16b may cover at least one of the openings 20a, 20b, and 20c. The left end, the front end, and the right end of the base plate 16b extend to the upper end surface 20d of the toilet body 20. This covers and conceals the covers 80, 82, and 84 disposed below the base plate 16b. The moving device 16c supports the functional unit main body 16a so that it can move relative to the base plate 16b. The functional unit main body 16a includes components for performing various functions of the functional unit 16. The functional part body 16a includes, for example, a nozzle for performing a private part washing function, a heater for heating washing water, and a motor for performing a function of opening and closing the toilet lid and the toilet seat 14. The functional part body 16a is arranged so as to be movable between an initial position (see FIG. 13) and a moving position (see FIG. 14) by a moving device 16c. In the initial position, the functional part body 16a is placed on the base plate 16b. In the moving position, the functional part body 16a is arranged facing the base plate 16b with a predetermined gap therebetween. The predetermined gap between the functional part body 16a and the base plate 16b is a gap large enough that a user can insert at least one of a hand and a cleaning tool between the functional part body 16a and the base plate 16b to clean between the functional part body 16a and the base plate 16b. According to this configuration, even while the user is moving the functional unit body 16a to the moving position for cleaning, the openings 20a, 20b, and 20c are covered and hidden by the base plate 16b and are not visible to the user. Therefore, the user does not have to worry about the openings 20a, 20b, and 20c on the toilet body 20, making cleaning easy. Regarding the above, in a modified example, the toilet apparatus 10 does not need to be provided with the covers 80, 82, and 84 that cover the openings 20a, 20b, and 20c, respectively.

[0038] The toilet seat 14 is attached to the functional part body 16a. Therefore, the toilet seat 14 moves together with the functional part body 16a by the moving device 16c.

[0039] (Control Unit Configuration) As shown in Fig. 1, the control unit 100 is housed in the toilet body 20. The control unit 100 is communicatively connected to each of the pump 42, the switching valve 46, the functional unit 16, and the seating sensor 90. The control unit 100 controls the pump 42, the switching valve 46, the functional unit 16, and the seating sensor 90. The control unit 100 is further communicatively connected to operation units operated by the user, such as a flush button, a remote controller, etc.

[0040] The control unit 100 includes a CPU and a memory. The memory has a volatile and non-volatile storage unit. The control unit 100 controls the pump 42, the switching valve 46, the functional unit 16, and the seating sensor 90 by the CPU executing processing according to a computer program pre-stored in the memory.

[0041] When flush water is to be supplied to the toilet bowl 22 by a user operation or the like, the control unit 100 controls the pump 42 and the switching valve 46 to supply flush water to the toilet bowl 22 from the discharge nozzles 50, 52, the discharge member 60 and the discharge opening 54. Waste in the toilet bowl 22 is discharged to the outside of the toilet body 20 by the flush water.

[0042] When cleaning the gap between the functional part body 16a and the toilet body 20 by user operation or the like, the control unit 100 controls the movement device 60c to move the functional part body 16a from the initial position to the movement position. When the functional part body 16a is placed in the movement position, a gap is created between the base plate 16b and the functional part body 16a. Therefore, the user can insert his / her hand into the gap and clean the gap between the functional part body 16a and the toilet body 20.

[0043] (Effects of the embodiment) In the configuration of this embodiment, openings 20a, 20c are formed in the toilet body 20, through which the discharge nozzles 50, 52 can pass. Therefore, the discharge nozzles 50, 52 can be easily disposed inside the toilet body 20 through the openings 20a, 20c.

[0044] The outlet 58a of the discharge nozzles 50, 52 has an elongated shape. This allows flushing water to flow from the outlet 58a over a wide range in the vertical direction. The discharge nozzles 50, 52 having an elongated outlet 58a have a vertically elongated shape to match the shape of the outlet 58a. When the discharge nozzles 50, 52 are attached to the toilet body 20, the discharge nozzles 50, 52 can be placed inside the toilet body 20 through the openings 20a, 20c. With this configuration, in order to place the discharge nozzles 50, 52 inside the toilet body 20, it is not necessary to widen the mounting hole 20e of the toilet body 20 to the extent that the discharge nozzles 50, 52 can pass through.

[0045] In this embodiment, the branch pipe 48a is an example of a "supply pipe." The discharge nozzle 50 and the communication member 45 are an example of a "cylindrical member." The opening 20a is an example of an "opening." The mounting hole 20e is an example of a "mounting hole."

[0046] Aspects of the technology disclosed in this specification are listed below.

[0047] In a first aspect, a toilet device may include a toilet body having a toilet bowl, a supply pipe that supplies flushing water toward the toilet bowl, and a tubular member that is disposed inside the toilet body and has one end connected to the supply pipe. The toilet body may have an opening through which the tubular member can pass. The opening may open to a surface of the toilet body along the direction in which the tubular member extends.

[0048] In a second aspect, in the first aspect, the cylindrical member may have a nozzle portion at the other end. The nozzle portion may have an outlet that discharges the flush water from the supply pipe toward the toilet bowl. The length of the outlet in a first direction may be greater than the length in a second direction perpendicular to the first direction.

[0049] In a third aspect, in the second aspect, the toilet body may further have a mounting hole for mounting the tubular member. The length of the opening diameter of the mounting hole may be smaller than the length of the discharge port in the first direction.

[0050] In a fourth aspect, in any one of the first to third aspects, the opening may be open upward on the top surface of the toilet body.

[0051] In a fifth aspect, in any one of the first to fourth aspects, the toilet apparatus may further include a cover that covers the opening.

[0052] In a sixth aspect, in the fifth aspect, the cover may be made of resin, and the cover may be fixed to the toilet body by an adhesive tape.

[0053] In a seventh aspect, in any one of the fifth and sixth aspects, the cover may watertightly cover the opening of the toilet body.

[0054] In an eighth aspect, in any one of the first to seventh aspects, the toilet apparatus may further include a functional part, and the opening may be covered by the functional part.

[0055] In a ninth aspect, in the eighth aspect, the functional unit may include a base plate that covers the opening and is attached to the toilet body, a functional unit main body that is arranged to be movable between an initial position placed on the base plate and a moving position that is arranged opposite the base plate with a predetermined gap between them, and a moving device that supports the functional unit main body movably relative to the base plate.

[0056] Specific examples of the technology disclosed in this specification have been described above in detail. These are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes to the specific examples exemplified above. Modifications of the above embodiment are listed below.

[0057] (Variation 1) In this embodiment, the opening 20a opens on the upper end surface 20d. The upper end surface 20d is arranged parallel to the direction in which the discharge nozzle 50 extends. That is, the upper end surface 20d is arranged parallel to the direction in which the flushing water flows at the connection portion (i.e., the communication member 45) between the branch pipe 48a and the discharge nozzle 50. The upper end surface 20d is arranged along the direction in which the flushing water flows through the portion of the toilet body 20 to which the discharge nozzle 50 is attached (i.e., the mounting hole 20e). In a modified example, the opening 20a may open on a surface inclined with respect to a plane parallel to the direction in which the discharge nozzle 50 extends. In this case, the upper end surface 20d may be arranged at an angle other than perpendicular to the direction in which the flushing water flows at the connection portion (i.e., the communication member 45) between the branch pipe 48a and the discharge nozzle 50. It can be said that the upper end surface 20d is arranged along the direction in which the flushing water flows at the connection portion (i.e., the communication member 45) between the branch pipe 48a and the discharge nozzle 50. The upper end surface 20d may be arranged at an angle other than perpendicular to the direction in which flush water flows in the portion of the toilet body 20 to which the discharge nozzle 50 is attached (i.e., the mounting hole 20e). It can be said that the upper end surface 20d is arranged along the direction in which flush water flows in the portion of the toilet body 20 to which the discharge nozzle 50 is attached (i.e., the mounting hole 20e).

[0058] (Variation 2) The opening 20a may open to the left side surface of the toilet body 20. That is, the opening 20a may be formed in the outer wall 74a. In this case, the outer surface of the outer wall 74a may be part of the outer surface of the toilet body 20. The opening 20a may be located above the lower wall 74e of the toilet body 20. With this configuration, flushing water that accumulates in the lower wall 74e is less likely to leak out onto the outer surface of the toilet body 20 through the opening.

[0059] (Variation 3) The toilet body may have a mounting hole to which the nozzle portion 58 of the discharge nozzle 50 is attached. The supply pipe 66 and the discharge member 60 are an example of a "cylindrical member." The opening 20b is an example of an "opening."

[0060] (Variation 4) The toilet body 20 does not have to have the entire opening 20a covered by the base plate 16b of the functional part 16. The toilet body 20 may have at least a portion of the opening 20a covered by the base plate 16b of the functional part 16.

[0061] (Variation 5) The functional portion main body 16a may be fixed to the toilet main body 20 in a predetermined position (ie, the initial position shown in FIG. 12) by a base plate 16b.

[0062] The technical elements described in the specification and / or drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. The technologies illustrated in the specification and / or drawings can achieve multiple objectives simultaneously, and achieving one of these objectives is itself technically useful.
