In one embodiment, air passage 13 is composed of first air passage 13a and second air passage 13b.

[0024] (Toilet seat 3) Fig. 7 is a partially cutaway plan view that shows a schematic view of the movement of the flushing device 5 of one embodiment. As shown in Figs. 1 and 7, the toilet seat 3 is annular in plan view. The toilet seat 3 has a seat surface 30 on which a user sits, and a back surface 31 that faces the opposite side to the seat surface 30. A plurality of rubber legs 32 are attached to a part of the back surface 31 of the toilet seat 3.

[0025] The rear end of the toilet seat 3 is swingably connected to the mounting part 15 (see FIG. 3) which is attached to the mounting hole 211 of the toilet body 2. The toilet seat 3 is swingable between a laid-down position in which the back surface 31 of the toilet seat 3 is aligned with the top end surface (i.e., the upper surface 210) of the toilet body 2, and an upright position in which the toilet seat 3 stands upright relative to the top end surface of the toilet body 2. The legs 32 of the toilet seat 3 abut against the top end surface of the toilet body 2. As a result, a gap is formed between the back surface 31 of the toilet seat 3 and the top end surface of the toilet body 2 when in the laid-down position.

[0026] (Toilet lid 4) As shown in Figures 2 and 3, the toilet lid 4 has a toilet lid body 40 that covers the seat surface 30 of the toilet seat 3, and a toilet lid side wall 41 that extends from the outer peripheral edge of the toilet lid body 40 and covers the outer peripheral surface of the toilet seat 3. The toilet lid body 40 is plate-shaped. Similarly, the toilet lid side wall 41 is plate-shaped. When viewed in the thickness direction of the toilet lid body 40 (i.e., the up-down direction in Figure 2), the toilet lid body 40 has a semi-elliptical shape. When viewed in the thickness direction of the toilet lid body 40, the toilet lid side wall 41 has a semi-elliptical ring shape.

[0027] The rear end of the toilet lid 4 is swingably connected to the attachment part 15. The toilet lid 4 is swingable between a closed position in which the toilet lid body 40 is aligned along the upper end surface of the toilet body 2, and an open position in which the toilet lid body 40 stands upright against the upper end surface of the toilet body 2.

[0028] A seal portion 16 configured to seal the gap between the toilet lid 4 and the toilet bowl body 2 is provided on the outer peripheral edge of the toilet lid 4 (i.e., the lower end of the toilet lid side wall 41). Like the toilet lid side wall 41, the seal portion 16 is also semi-elliptical and annular. More specifically, the seal portion 16 is provided around the entire circumference of the lower end of the toilet lid side wall 41. The seal portion 16 is, for example, a rubber packing. The seal portion 16 may be made of resin, or may have a labyrinth structure provided on the underside of the toilet lid side wall 41.

[0029] When the toilet lid 4 is in the closed position, the seal portion 16 abuts against the upper end surface of the toilet body 2, closing the gap between the toilet lid side wall 41 and the upper end surface of the toilet body 2. This makes it possible to prevent water and air from leaking out from between the toilet lid side wall 41 of the toilet lid 4 and the upper end surface of the toilet body 2.

[0030] A rail 42 is provided on the underside of the toilet lid body 40, which runs along the circumferential direction of the toilet seat 3. The rail 42 is made up of an inner rail 420, an outer rail 421, and an intermediate rail 422, which are semi-elliptical in shape when viewed from above. The intermediate rail 422 is provided with a rack gear and a groove recessed upward (i.e., in the direction toward the toilet lid body 40) over its entire circumferential length.

[0031] As shown in Fig. 7, a first stopper 43 and a second stopper 44 are provided on the back surface of the toilet lid body 40. The first stopper 43 is provided so as to face an end face of a first end in the length direction of the rail 42 (e.g., one end of the rail 42). The second stopper 44 is provided so as to face an end face of a second end in the length direction of the rail 42 (e.g., the other end of the rail 42). Note that the rail 42 is not shown in Fig. 7.

[0032] The first stopper 43 and the second stopper 44 are flat plates arranged at right angles to the toilet lid body 40. The first stopper 43 and the second stopper 44 each have a thickness direction parallel to the circumferential direction of the toilet seat 3. In one embodiment, the thickness direction of the first stopper 43 is inclined slightly to the left with respect to the front-to-rear direction. The thickness direction of the second stopper 44 is inclined slightly to the right with respect to the front-to-rear direction.

[0033] The first stopper 43 and the second stopper 44 are positioned in the same position in the front-rear direction. A first buffer member 45a is attached to the surface of the first stopper 43 facing the rail 42 (i.e., the front surface). A second buffer member 45b is attached to the surface of the second stopper 44 facing the rail 42 (i.e., the front surface). Each of the first buffer member 45a and the second buffer member 45b is in the form of a sheet and is made of, for example, rubber.

[0034] (Blower 8) An air blower 8 is attached to the surface of the toilet lid body 40 (i.e., the surface opposite the toilet seat 3). An insertion hole 400 is provided in the center of the toilet lid body 40, through which a part of the air blower pipe 14 connected to the air blower 8 passes.

[0035] (Air pipe 14) The air duct 14 has a fixed duct 140 attached to the front side of the toilet lid body 40 and a movable duct 141 that communicates with the fixed duct 140 and is disposed on the back side of the toilet lid body 40.

[0036] The movable pipe 141 is an expandable pipe. One end (more specifically, the upstream end) of the movable pipe 141 is connected to the fixed pipe 140. The other end (more specifically, the downstream end) of the movable pipe 141 is connected to the movable part 10 via the switching mechanism 9. As shown in Fig. 3, as the movable part 10 moves in the circumferential direction of the toilet seat 3, the movable pipe 141 automatically rotates around the insertion hole 400 while expanding and contracting.

[0037] As shown in FIG. 3, in one embodiment, the movable tube 141 has a first tube section 142 connected to the fixed tube 140, and a second tube section 143 connected to the movable section 10 via a switching mechanism 9. The inner diameter of the second tube section 143 is slightly larger than the outer diameter of the first tube section 142. A part of the first tube section 142 is slidably fitted inside the second tube section 143. This makes the movable tube 141 extendable and retractable. Note that it is sufficient for the movable tube 141 to be extendable and retractable. The movable tube 141 may be, for example, a bellows-shaped tube.

[0038] (Movable part 10) The movable part 10 shown in Fig. 1 is attached to the toilet lid body 40 of the toilet lid 4 so as to move in the circumferential direction of the toilet seat 3. The movable part 10 moves reciprocally in the circumferential direction of the toilet seat 3 by being guided by a rail 42. The movable part 10 is movable between a first movable position facing one part of the circumferential direction of the toilet seat 3, and a second movable position facing another part of the circumferential direction of the toilet seat 3. In one embodiment, the one part and the other part of the circumferential direction of the toilet seat 3 are left and right portions of the toilet seat 3 that sandwich the rear part 330 of the central opening 33.

[0039] The first movable position is a position when the movable part 10 hits the first stopper 43 at the first end in the longitudinal direction of the rail 42. That is, in Fig. 7, the first movable position is the position where the movable part 10 is located on the left side indicated by the two-dot chain line.

[0040] The second movable position is a position when the movable part 10 hits the second stopper 44 at the second end in the longitudinal direction of the rail 42. That is, in Fig. 7, the second movable position is a position where the movable part 10 is located on the right side indicated by the two-dot chain line. The front-rear position of the first movable position and the front-rear position of the second movable position are the same.

[0041] Fig. 4 is a perspective view showing a part of the flushing device 5 included in the toilet seat device 1 of one embodiment. As shown in Fig. 4 and Fig. 7, the movable part 10 has rollers 101 that roll on the rails 42. The rollers 101 are composed of an inner roller 102 that rolls on the inner rail 420, an outer roller 103 that rolls on the outer rail 421, and an intermediate roller 104 that rolls in a groove of the intermediate rail 422. The movable part 10 further has a pinion 105 that meshes with a rack gear provided on the intermediate rail 422, and a motor 106 that rotates the pinion 105.

[0042] The movable part 10 moves in the circumferential direction of the toilet seat 3 as the pinion 105 rotates while meshing with the rack gear of the intermediate rail 422 due to the rotation of the motor 106, and the rollers 101 roll on the rail 42. At this time, the inner rollers 102, outer rollers 103, and intermediate rollers 104 roll on the inner rail 420, outer rail 421, and intermediate rail 422, respectively, thereby suppressing the inclination of the movable part 10 relative to the horizontal direction. As a result, the relative positional relationship between the moving movable part 10 and the toilet seat 3 is approximately constant at any position in the circumferential direction of the toilet seat 3.

[0043] 4, the movable part 10 has a driving part 107, a cleaning water supply part 6 fixed to the driving part 107, and an air supply part 7 fixed to the driving part 107. The driving part 107 is provided with a roller 101, a pinion 105, and a motor 106.

[0044] The flush water supply section 6 and the air supply section 7 are aligned in the circumferential direction of the toilet seat 3 (that is, in the left-right direction in FIG. 4).

[0045] (Cleaning water supply unit 6) As shown in Figs. 4 and 5, the flush water supply unit 6 has a main body portion 61 extending along part of the circumferential direction of the seat surface 30 of the toilet seat 3, and a first arm portion 62 extending downward from one end of the main body portion 61 in the longitudinal direction. The flush water supply unit 6 further has a second arm portion 63 extending downward from the other end of the main body portion 61 in the longitudinal direction. The first arm portion 62 is located outside the outer periphery of the toilet seat 3. The second arm portion 63 is located inside the inner periphery of the toilet seat 3. The lower end of the first arm portion 62 is located above the upper end surface (i.e., upper surface 210) of the toilet body 2. The protruding length of the second arm portion 63 from the main body portion 61 is longer than the protruding length of the first arm portion 62 from the main body portion 61. The lower end of the second arm portion 63 is located below the upper end surface (i.e., upper surface 210) of the toilet body 2.

[0046] The main body 61 is provided with a water supply port 64 to which the water supply pipe 12 is connected. In one embodiment, the water supply port 64 is composed of a first water supply port 64a to which the first water supply pipe 12a is connected and a second water supply port 64b to which the second water supply pipe 12b is connected. As shown in FIG. 7, the first water supply pipe 12a is connected to a first joint 120a connected to a water supply source. The second water supply pipe 12b is connected to a second joint 120b connected to a water supply source. The first joint 120a and the second joint 120b are separate joints.

[0047] 5, the wash water supply unit 6 is provided with a first water passage 11a that communicates with a first water supply port 64a, and a second water passage 11b that communicates with a second water supply port 64b. The first water passage 11a and the second water passage 11b are not connected to each other. In other words, the first water passage 11a and the second water passage 11b are separate water passages.

[0048] (Cleaning nozzle 60) The cleaning nozzle 60 includes a first cleaning nozzle 60a configured to discharge cleaning water toward the seat surface 30 of the toilet seat 3, and a second cleaning nozzle 60b configured to discharge cleaning water toward the underside 31 of the toilet seat 3. The cleaning nozzle 60 further includes a toilet lid cleaning nozzle 60c configured to discharge cleaning water toward the inner peripheral surface of the toilet lid side wall 41 of the toilet lid 4, and a bowl cleaning nozzle 60d configured to discharge cleaning water toward the upper end of the bowl 20. The cleaning water is not limited to water, and may be hot water, foam, disinfectant water, or water containing detergent. The cleaning water may also be water from which metal components have been removed by a water softener to prevent limescale.

[0049] The first flushing nozzle 60a is provided at the inner corner formed by the first arm portion 62 and the main body portion 61. Therefore, flushing water is discharged from the first flushing nozzle 60a onto the seat surface 30 of the toilet seat 3 toward the inner periphery of the toilet seat 3. The seat surface 30 of the toilet seat 3 is cleaned by flushing water flowing from the outer periphery of the toilet seat 3 to the inner periphery.

[0050] The second cleaning nozzle 60b is provided on the inner surface (i.e., the surface facing the toilet seat 3) of the lower end of the first arm portion 62. Therefore, cleaning water is discharged from the second cleaning nozzle 60b toward the inner periphery of the toilet seat 3 onto the back surface 31 of the toilet seat 3. In one embodiment, cleaning water is also discharged from the second cleaning nozzle 60b toward the upper end surface (i.e., the upper surface 210) of the toilet body 2 facing the back surface 31 of the toilet seat 3. As a result, the back surface 31 of the toilet seat 3 and the upper end surface (i.e., the upper surface 210) of the toilet body 2 facing it are cleaned by the cleaning water heading toward the inner periphery of the toilet seat 3.

[0051] The toilet lid flushing nozzle 60c is provided on the outer surface (i.e., the surface facing the toilet lid side wall 41) of the upper part of the first arm portion 62. The first flushing nozzle 60a, the toilet lid flushing nozzle 60c, and the second flushing nozzle 60b are lined up in this order in the vertical direction.

[0052] Bowl cleaning nozzle 60d is provided on the outer surface (i.e., the surface facing toilet seat 3) of the lower end of second arm portion 63. In one embodiment, as shown in FIG. 1, second arm portion 63 is provided with two bowl cleaning nozzles 60d. As shown in FIG. 5, each of the two bowl cleaning nozzles 60d opens obliquely downward and toward the inner circumferential surface of the upper end of bowl 20. As shown in FIG. 1, the openings of the two bowl cleaning nozzles 60d are spaced apart from each other by approximately 120 degrees in a plan view.

[0053] The first flushing nozzle 60a and the toilet lid flushing nozzle 60c are connected to the first water passage 11a. The second flushing nozzle 60b and the two bowl flushing nozzles 60d are connected to the second water passage 11b.

[0054] In one embodiment, the opening area of ​​the tip of the second cleaning nozzle 60b is smaller than the opening area of ​​the tip of the first cleaning nozzle 60a, so that cleaning water is more likely to be discharged from the second cleaning nozzle 60b with more force than from the first cleaning nozzle 60a.

[0055] In one embodiment, the first water passage 11a that supplies washing water to the first washing nozzle 60a and the toilet lid washing nozzle 60c and the second water passage 11b that supplies washing water to the second washing nozzle 60b and the bowl washing nozzle 60d are separate. Therefore, it is possible to change the washing power of the washing water by changing the water pressure, temperature, type, or a combination thereof between the first water passage 11a and the second water passage 11b. Therefore, it is also possible to supply washing water with high washing power from the second washing nozzle 60b and the bowl washing nozzle 60d to the upper end of the bowl 20 and the back surface 31 of the toilet seat 3, which are prone to adhesion of urine and feces splashed on the surface of the bowl 20.

[0056] (Air supply section 7) 4 and 6, the air supply unit 7 has a main body portion 71 extending along part of the circumferential direction of the seat surface 30 of the toilet seat 3, and an arm portion 72 extending from one longitudinal end of the main body portion 71. The arm portion 72 is located outside the outer periphery of the toilet seat 3. The arm portion 72 is provided with a drying nozzle 70 that ejects air onto the toilet seat 3.

[0057] (Drying nozzle 70) In one embodiment, the drying nozzle 70 is composed of a first drying nozzle 70a, a second drying nozzle 70b, and a toilet lid drying nozzle 70c. The first drying nozzle 70a is configured to discharge air toward the seat surface 30 of the toilet seat 3. The second drying nozzle 70b is configured to discharge air toward the underside 31 of the toilet seat 3. The toilet lid drying nozzle 70c is configured to discharge air toward the toilet lid side wall 41 of the toilet lid 4. That is, in one embodiment, the drying nozzle 70 discharges air toward the toilet seat 3 and its surroundings.

[0058] A switching mechanism 9 is attached to the main body 71. As shown in Fig. 6, Fig. 9A, and Fig. 9B, a first connection port 73a and a second connection port 73b are provided in the main body 71. One connection port selected from the first connection port 73a and the second connection port 73b is connected to the air passage 18 via the switching mechanism 9.

[0059] 6, the air supply unit 7 is provided with a first air passage 13a communicating with the first connection port 73a and a second air passage 13b communicating with the second connection port 73b. The first air passage 13a and the second air passage 13b are not connected to each other. The first air passage 13a and the second air passage 13b are separate air passages.

[0060] The first air passage 13a communicates with the first drying nozzle 70a. The second air passage 13b communicates with the second drying nozzle 70b and the toilet lid drying nozzle 70c. In other words, the toilet lid drying nozzle 70c communicates with the air passage that supplies air to the second drying nozzle 70b (i.e., the second air passage 13b).

[0061] The first drying nozzle 70a is provided at the upper end of the arm portion 72. Therefore, air is discharged from the first drying nozzle 70a onto the seat surface 30 of the toilet seat 3 toward the inner periphery of the toilet seat 3.

[0062] The second drying nozzle 70b is provided at the lower end of the arm portion 72. Therefore, air is discharged from the second drying nozzle 70b toward the inner periphery of the back surface 31 of the toilet seat 3. In one embodiment, air is also discharged from the second drying nozzle 70b toward the upper end surface (i.e., upper surface 210) of the toilet body 2 facing the back surface 31 of the toilet seat 3. Therefore, air is discharged from the second drying nozzle 70b toward the inner periphery of the toilet seat 3 toward the back surface 31 of the toilet seat 3 and the upper end surface of the toilet body 2 facing thereto.

[0063] The toilet lid drying nozzle 70c is provided in the vertical middle of the arm portion 72. The toilet lid drying nozzle 70c opens toward the toilet lid side wall 41 of the toilet lid 4. The toilet lid drying nozzle 70c is located between the first drying nozzle 70a and the second drying nozzle 70b. The first drying nozzle 70a, the toilet lid drying nozzle 70c, and the second drying nozzle 70b are lined up in this order in the vertical direction.

[0064] The first drying nozzle 70a is positioned next to the first washing nozzle 60a in the left-right direction. The vertical position of the first drying nozzle 70a and the vertical position of the first washing nozzle 60a are the same. The toilet lid drying nozzle 70c is positioned next to the toilet lid washing nozzle 60c in the left-right direction. The vertical position of the toilet lid drying nozzle 70c and the vertical position of the toilet lid washing nozzle 60c are the same. The second drying nozzle 70b is positioned next to the second washing nozzle 60b in the left-right direction. The vertical position of the second drying nozzle 70b and the vertical position of the second washing nozzle 60b are the same.

[0065] Therefore, when the movable part 10 moves, the air from the first drying nozzle 70a and the cleaning water from the first flushing nozzle 60a are discharged to approximately the same location on the seat surface 30 of the toilet seat 3. Similarly, the air from the toilet lid drying nozzle 70c and the cleaning water from the toilet lid flushing nozzle 60c are discharged to approximately the same location on the inner circumferential surface of the toilet lid side wall 41. Similarly, the air from the second drying nozzle 70b and the cleaning water from the second flushing nozzle 60b are discharged to approximately the same location on the underside surface 31 of the toilet seat 3.

[0066] As shown in Fig. 4, the tip of the second drying nozzle 70b is provided with two openings 74 arranged vertically. Therefore, the air discharged from the second drying nozzle 70b is likely to hit both the underside 31 of the toilet seat 3 and the upper end surface (i.e., the upper surface 210) of the toilet body 2.

[0067] (Switching mechanism 9) The switching mechanism 9 shown in Fig. 4 and Fig. 6 is configured to switch the communication state between a first communication state in which only the first drying nozzle 70a of the first drying nozzle 70a and the second drying nozzle 70b is in communication with the blower 8, and a second communication state in which only the second drying nozzle 70b of the first drying nozzle 70a and the second drying nozzle 70b is in communication with the blower 8. The switching mechanism 9 includes a switch 90 that is pressed by contacting a peripheral portion of the movable part 10 (in one embodiment, the first stopper 43 or the second stopper 44) when the movable part 10 reaches the first movable position and the second movable position. The switching mechanism 9 further includes a switching part 91 (see Fig. 8) configured to switch the communication state from the first communication state to the second communication state or from the second communication state to the first communication state when the switch 90 is pressed.

[0068] 8 is a perspective view showing a switching unit 91 of the switching mechanism 9 included in the cleaning device 5 of one embodiment. As shown in FIGS. 6 and 8, the switching unit 91 has an air passage 910 therein. The air passage 910 includes a first end 911 communicating with the blower 8 and a second end 912 communicating with the first drying nozzle 70a or the second drying nozzle 70b. The switching unit 91 moves between a first communication position where the second end 912 communicates with the first drying nozzle 70a and a second communication position where the second end 912 communicates with the second drying nozzle 70b.

[0069] When the switch 90 is pressed, the switching unit 91 rotates and switches from the first communication position to the second communication position, or from the second communication position to the first communication position. In more detail, when a first end in the length direction of the switch 90 is pressed, the switching unit 91 rotates and switches from the first communication position to the second communication position. When a second end in the length direction of the switch 90 (i.e., the end opposite to the first end) is pressed, the switching unit 91 moves from the second communication position to the first communication position. This will be described in detail later.

[0070] As shown in FIG. 4, the switching mechanism 9 further includes a connecting member 92 that connects the switch 90 and the switching portion 91, and a case 93 that holds the switching portion 91 rotatably.

[0071] In one embodiment, the switch 90 is a rod-shaped member movably supported by the drive unit 107 of the movable unit 10. The switch 90 is longer in the circumferential direction of the toilet seat 3 (i.e., the left-right direction in FIG. 4) than the movable unit 10, and both ends in the longitudinal direction protrude in the circumferential direction of the toilet seat 3 beyond the movable unit 10. The switch 90 is movable in its longitudinal direction. When the movable unit 10 moves between the first movable position and the second movable position, the switch 90 moves in the longitudinal direction by hitting the first stopper 43 or the second stopper 44.

[0072] A connecting member 92 is fixed to a portion of the switch 90 in the longitudinal direction. The connecting member 92 moves in the same direction as the switch 90 as the switch 90 moves.

[0073] As shown in Fig. 8, the outer shape of switching unit 91 is cylindrical with a central axis parallel to the up-down direction. Switching unit 91 has air passage 910 inside. A first end 911 of air passage 910 opens at the center of the upper surface of switching unit 91. A second end 912 of air passage 910 opens at a part of the outer circumferential surface of switching unit 91. A pin-shaped rotation operation unit 913 protrudes upward from a part of the upper surface of switching unit 91.

[0074] As shown in FIG. 4, in one embodiment, the case 93 is formed by combining two divided bodies, an upper one and an lower one. FIG. 9A is a plan view showing the state of switching by the switching mechanism 9 of one embodiment. FIG. 9B is a plan view showing the state of switching by the switching mechanism 9 of one embodiment. As shown in FIG. 4, FIG. 9A, and FIG. 9B, the case 93 is provided with a cylindrical connection port 930 to which the blower tube 14 is connected, and an arc-shaped hole 931 through which the rotation operation part 913 is passed. The case 93 is further provided with a first communication passage 932 that communicates the second end 912 with the first connection port 73a, and a second communication passage 933 that communicates the second end 912 with the second connection port 73b. The first communication passage 932 and the second communication passage 933 are not connected to each other and are separate air passages.

[0075] The switching unit 91 is rotatably disposed in the case 93. A first end 911 of the air passage 910 of the switching unit 91 communicates with the connection port 930. A rotation operation unit 913 of the switching unit 91 protrudes upward from an arc-shaped hole 931 of the case 93. The rotation operation unit 913 is connected to the switch 90 via a connecting member 92. When the rod-shaped switch 90 advances and retreats in its length direction, the rotation operation unit 913 moves along the circumferential direction of the arc-shaped hole 931. As a result, the switching unit 91 switches between a first communication position where a second end 912 of the air passage 910 communicates with a first communication passage 932 and a second communication position where the second end 912 communicates with a second communication passage 933.

[0076] In one embodiment, when the movable part 10 reaches the first movable position or the second movable position, a first end or a second end (the end opposite to the first end) of the switch 90 in the longitudinal direction hits the first stopper 43 or the second stopper 44, and the switch 90 moves in the longitudinal direction. This causes the switching part 91 to rotate, and the second end 912 of the air passage 910 to communicate with either the first air passage 13a or the second air passage 13b, and the air from the blower 8 is supplied to either the first drying nozzle 70a or the second drying nozzle 70b.

[0077] The toilet seat device 1 further has a control unit that controls the movable part 10, the flush water supply part 6, and the air supply part 7. The control unit is a device whose main component is a computer system such as a microcomputer. The movement by the movable part 10, the supply of flush water by the flush water supply part 6, and the supply of air by the air supply part 7 are controlled by the control unit. As a result, in the toilet seat device 1 of one embodiment, the toilet seat 3 and its surroundings can be automatically washed.

[0078] 1 and 7, the toilet seat apparatus 1 further includes a cover 19 attached to the toilet lid body 40 of the toilet lid 4. The cover 19 covers the movable pipe 141 of the air supply pipe 14, the first water supply pipe 12a, and the second water supply pipe 12b from below, preventing these from being exposed.

[0079] As shown in Fig. 1, a toilet seat device 1 according to an embodiment is mounted on a toilet body 2 to form a toilet device 100. The toilet seat device 1 is electrically connected to a commercial power source. The first joint 120a and the second joint 120b of the toilet seat device 1 are each connected to a water supply source.

[0080] 2-3. Operation of the toilet seat device The toilet seat apparatus 1 and the toilet bowl apparatus 100 of one embodiment operate, for example, as follows.

[0081] When the user finishes using the toilet device 100 and the toilet lid 4 is closed automatically or manually, the flushing device 5 starts flushing the toilet seat 3.

[0082] First, the movable part 10 located at the first movable position (i.e., the movable part 10 on the left side in FIG. 7) moves in the circumferential direction of the toilet seat 3 toward the second movable position. At this time, flushing water is supplied from the water supply source to the flushing water supply part 6 via the first water supply pipe 12a and the second water supply pipe 12b. As a result, flushing water is discharged from each of the first flushing nozzle 60a, the second flushing nozzle 60b, the toilet lid flushing nozzle 60c, and the bowl flushing nozzle 60d. As a result, the seat surface 30 and the back surface 31 of the toilet seat 3, the inner peripheral surface of the toilet lid side wall 41, and the upper end of the bowl 20 are washed with the flushing water.

[0083] When the movable part 10 reaches the second movable position, the supply of flush water to the flush water supply part 6 is stopped. At this time, as shown in FIG. 9B, one end of the switch 90 in the length direction hits the second stopper 44, and the switching part 91 rotates. As a result, the second end 912 of the air passage 910 of the switching part 91 moves to the second communication position in which the air passage 910 communicates with the second communication passage 933. Then, the air passage 910 communicates with the second connection port 73b and the second air passage 13b. As a result, the blower 8 communicates with the second drying nozzle 70b and the toilet lid drying nozzle 70c via the blower pipe 14 and the second air passage 13b. At this time, the second end 912 of the air passage 910 of the switching part 91 does not communicate with the first communication passage 932, and the air passage 910 does not communicate with the first connection port 73a and the first air passage 13a. Therefore, the blower 8 does not communicate with the first drying nozzle 70a.

[0084] Next, the movable part 10, which is located at the second movable position, moves in the circumferential direction of the toilet seat 3 toward the first movable position. At this time, air is supplied from the blower device 8 to the blower duct 14 and the second air passage 13b, and air is discharged from the second drying nozzle 70b and the toilet lid drying nozzle 70c. This dries the underside 31 of the toilet seat 3 and the upper end surface (i.e., the upper surface 210) of the toilet body 2 facing it, and dries the inner peripheral surface of the toilet lid side wall 41. At this time, air is not discharged from the first drying nozzle 70a.

[0085] When the movable part 10 reaches the first movable position, as shown in FIG. 9A, the other end of the switch 90 in the length direction hits the first stopper 43, and the switching part 91 rotates. As a result, the second end 912 of the air passage 910 of the switching part 91 moves to the first communication position in which the air passage 910 communicates with the first communication passage 932. Then, the air passage 910 communicates with the first connection port 73a and the first air passage 13a. As a result, the blower 8 communicates with the first drying nozzle 70a via the blower pipe 14 and the first air passage 13a. At this time, the second end 912 of the air passage 910 of the switching part 91 does not communicate with the second communication passage 933, and the air passage 910 does not communicate with the second connection port 73b and the second air passage 13b. Therefore, the blower 8 does not communicate with the second drying nozzle 70b and the toilet lid drying nozzle 70c.

[0086] Next, the movable part 10, which is located at the first movable position, moves in the circumferential direction of the toilet seat 3 toward the second movable position. At this time, air is supplied from the blower device 8 to the blower pipe 14 and the first air passage 13a, and the air is discharged from the first drying nozzle 70a. This dries the seat surface 30 of the toilet seat 3. At this time, air is not discharged from the second drying nozzle 70b and the toilet lid drying nozzle 70c.

[0087] When the movable part 10 reaches the second movable position, the air supply by the blower 8 stops, and the cleaning operation of the toilet seat 3 is completed. At this time, as shown in Fig. 9B, one end of the switch 90 in the longitudinal direction hits the second stopper 44, and the switching part 91 rotates. As a result, the second drying nozzle 70b and the toilet lid drying nozzle 70c communicate with the blower 8 via the air duct 14 and the second air passage 13b.

[0088] The discharge of the flushing water from the first flushing nozzle 60a and the toilet lid flushing nozzle 60c and the discharge of the flushing water from the second flushing nozzle 60b and the bowl flushing nozzle 60d may be shifted from each other. For example, when the movable part 10 moves from the first movable position to the second movable position, the flushing water may be discharged only from the second flushing nozzle 60b and the bowl flushing nozzle 60d. And, when the movable part 10 moves from the second movable position to the first movable position, the flushing water may be discharged only from the first flushing nozzle 60a and the toilet lid flushing nozzle 60c. In this case, even if the flushing water discharged toward the back surface 31 of the toilet seat 3, the upper end surface of the toilet body 2, and the inner peripheral surface of the upper end of the bowl 20 splashes on the seat surface 30 of the toilet seat 3 or the inner peripheral surface of the toilet lid side wall 41, it can be washed away.

[0089] 2-4.Effects In the toilet seat device 1 of the embodiment described above, water from the water supply source can be supplied to each of the first flushing nozzle 60a, the second flushing nozzle 60b, the toilet lid flushing nozzle 60c, and the bowl flushing nozzle 60d through the water supply passage 17. Therefore, in the toilet seat device 1 of the embodiment, the seat surface 30 and the back surface 31 of the toilet seat 3, the inner peripheral surface of the toilet lid side wall 41, and the upper end of the bowl 20 can be washed.

[0090] In the toilet seat device 1 of one embodiment, the seat surface 30 and back surface 31 of the toilet seat 3 and the inner peripheral surface of the toilet lid side wall 41 can be dried by air blown from the first drying nozzle 70a, the second drying nozzle 70b, and the toilet lid drying nozzle 70c. Therefore, in the toilet seat device 1 of one embodiment, the wash water remaining on the seat surface 30 and back surface 31 of the toilet seat 3 and the inner peripheral surface of the toilet lid side wall 41 can be removed.

[0091] In one embodiment of the toilet seat device 1, the water supply passage 17 is located between the toilet lid 4 and the toilet seat 3 when closed, so that the space between the toilet lid 4 and the toilet seat 3 can be effectively utilized as space for arranging the water supply passage 17.

[0092] In the toilet seat device 1 of one embodiment, the first drying nozzle 70a and the first cleaning nozzle 60a are aligned in the circumferential direction of the toilet seat 3. Similarly, the second drying nozzle 70b and the second cleaning nozzle 60b are aligned in the circumferential direction of the toilet seat 3. Similarly, the toilet lid drying nozzle 70c and the toilet lid cleaning nozzle 60c are aligned in the circumferential direction of the toilet seat 3. Therefore, in the toilet seat device 1 of one embodiment, it is easy to direct air toward the area where cleaning water is ejected, making it easy to effectively dry the area after cleaning.

[0093] In the toilet seat device 1 of one embodiment, a first cleaning nozzle 60a, a second cleaning nozzle 60b, a toilet lid cleaning nozzle 60c, and a bowl cleaning nozzle 60d are provided on the movable part 10 that moves in the circumferential direction of the toilet seat 3. Therefore, in the toilet seat device 1 of one embodiment, the seat surface 30 and the back surface 31 of the toilet seat 3, the inner peripheral surface of the toilet lid side wall 41, and the upper end part of the bowl 20 can each be cleaned in the circumferential direction of the toilet seat 3.

[0094] In the toilet seat apparatus 1 of one embodiment, the destinations of water supply from the water supply source are all concentrated in one movable part 10, so the number of water supply channels 17 connecting the water supply source and the cleaning nozzle 60 can be reduced.

[0095] In one embodiment of the toilet seat device 1, cleaning water is ejected from each of the first cleaning nozzle 60a and the second cleaning nozzle 60b toward the inner circumference of the toilet seat 3, thereby preventing cleaning water from being discharged to the outside of the toilet seat 3, i.e., the outside of the toilet lid 4.

[0096] In one embodiment of the toilet seat device 1, even if the cleaning water from the first cleaning nozzle 60a and the second cleaning nozzle 60b splashes from the seat surface 30 or the back surface 31 of the toilet seat 3 and adheres to the toilet lid side wall 41, it can be cleaned by the cleaning water from the toilet lid cleaning nozzle 60c.

[0097] In the toilet seat device 1 of one embodiment, the first water supply passage 17a (i.e., the first water passage 11a and the first water supply pipe 12a) that supplies water to the first flushing nozzle 60a can be used to supply flushing water to the toilet lid flushing nozzle 60c. Therefore, the toilet seat device 1 of one embodiment can be made more compact than when a separate water supply passage is provided exclusively for supplying flushing water to the toilet lid flushing nozzle 60c.

[0098] In the toilet seat device 1 of one embodiment, the supply of washing water to the bowl washing nozzle 60d can be made by using the second water supply passage 17b (i.e., the second water passage 11b and the second water supply pipe 12b) that supplies water to the second washing nozzle 60b. Therefore, in the toilet seat device 1 of one embodiment, it is easier to make it compact than when a dedicated water supply passage for supplying washing water to the bowl washing nozzle 60d is separately provided.

[0099] In the toilet seat device 1 of one embodiment, the first water supply passage 17a that supplies flushing water to the first flushing nozzle 60a and the toilet lid flushing nozzle 60c, and the second water supply passage 17b that supplies flushing water to the second flushing nozzle 60b and the bowl flushing nozzle 60d are separate water passages. Therefore, in the toilet seat device 1 of one embodiment, flushing water with higher cleaning power can be supplied to the second water supply passage 17b than the first water supply passage 17a, and the back surface 31 of the toilet seat 3 and the upper end of the bowl 20, which are prone to adhesion of urine and feces that splashed off the surface of the bowl 20, can be cleaned with flushing water with higher cleaning power.

[0100] In the toilet seat device 1 of one embodiment, a seal portion 16 is provided on the outer periphery of the toilet lid 4 to close the gap between the toilet body 2. Therefore, in the toilet seat device 1 of one embodiment, the wash water from each of the first wash nozzle 60a, the second wash nozzle 60b, and the toilet lid wash nozzle 60c is less likely to be discharged to the outside of the toilet seat 3 and the toilet lid 4 (i.e., the outside of the toilet device 100).

[0101] In the toilet seat device 1 of one embodiment, a gap is provided between the rear surface 31 of the toilet seat 3 and the upper end surface (i.e., the upper surface 210) of the toilet body 2. Therefore, in the toilet seat device 1 of one embodiment, the rear surface 31 of the toilet seat 3 and the upper end surface of the toilet body 2 can be cleaned together with cleaning water from the second cleaning nozzle 60b.

[0102] 3. Variations Next, a description will be given of modified examples of the above-mentioned toilet seat apparatus 1 and toilet bowl apparatus 100. The modified examples shown below can be appropriately combined.

[0103] The water supply passage 17 that connects the first cleaning nozzle 60a and the second cleaning nozzle 60b to the water source is not limited to separate water supply passages (i.e., the first water supply passage 17a and the second water supply passage 17b), but may be a single water supply passage.

[0104] The cleaning device 5 does not need to have the drying nozzle 70, and the seat surface 30 and the underside surface 31 of the toilet seat 3 and the inner surface of the toilet lid side wall 41 may be dried by other means such as a heater.

[0105] The cleaning device 5 does not have to have a movable part 10. In this case, for example, a plurality of sets of cleaning nozzles 60 may be provided on the toilet cover 4 so as to be positioned at intervals in the circumferential direction of the toilet seat 3.

[0106] The flushing device 5 only needs to have at least the first flushing nozzle 60a and the second flushing nozzle 60b, and may not have the toilet lid flushing nozzle 60c. The flushing device 5 may not have the bowl flushing nozzle 60d. In this case, the flushing water supply unit 6 may not have the second arm unit 63.

[0107] The tips of the first cleaning nozzle 60a and the second cleaning nozzle 60b do not have to open toward the inner periphery of the toilet seat 3. At least one of the first cleaning nozzle 60a and the second cleaning nozzle 60b may open toward the outer periphery of the toilet seat 3. Even in this case, in the toilet apparatus 100 of one embodiment, the seal portion 16 can prevent cleaning water discharged toward the outer periphery of the toilet seat 3 from being discharged to the outside of the toilet apparatus 100.

[0108] The seal portion 16 does not have to be provided on the outer peripheral edge of the toilet lid 4. In this case, it is preferable that the first flushing nozzle 60a and the second flushing nozzle 60b are each provided so as to open toward the inner peripheral side of the toilet seat 3.

[0109] Fig. 10 is a cross-sectional view showing a modified example of the toilet seat apparatus 1 of one embodiment and the toilet bowl apparatus 100 including the same. As in the modified example shown in Fig. 10, the toilet seat apparatus 1 may be provided with a bulging portion 310 that protrudes downward on the inner peripheral edge of the rear surface 31 of the toilet seat 3. In this modified example, the lower end of the bulging portion 310 is located within the opening at the upper end of the bowl 20 when the toilet lid 4 is closed, and is located below the upper end surface of the toilet body 2. A gap is formed between the bulging portion 310 and the inner peripheral surface of the bowl 20.

[0110] In the toilet seat device 1 of this modification, water discharged from the second flushing nozzle 60b from the outer periphery of the toilet seat 3 toward the underside 31 of the toilet seat 3 is guided by the bulging portion 310 and tends to flow into the bowl 20. This makes it possible to prevent the flushing water discharged from the second flushing nozzle 60b from splashing to places other than the underside 31 of the toilet seat 3 and the upper end surface of the toilet body 2.

[0111] The cleaning nozzle 60 may be provided so as to be able to switch between discharging cleaning water and discharging air. In other words, the cleaning nozzle 60 may also function as the drying nozzle 70.

[0112] The drying nozzle 70 may eject air that has been heated by a heater or the like.

[0113] The toilet apparatus 100 is not limited to a toilet seat apparatus 1 attached separately from the toilet body 2 on top of the toilet body 2, but may be one in which the toilet body 2 and the toilet seat apparatus 1 are provided integrally.

[0114] (summary) As in the embodiment and its modified examples described above, the toilet seat device 1 according to the first aspect of the present disclosure has the following configuration.

[0115] That is, the toilet seat device 1 of the first embodiment is attached on top of a toilet body 2 having a bowl 20. The toilet seat device 1 includes a toilet seat 3, a toilet lid 4, and a cleaning device 5 for cleaning the toilet seat 3. The cleaning device 5 has a first cleaning nozzle 60a configured to eject cleaning water toward the seat surface 30 of the toilet seat 3, and a second cleaning nozzle 60b configured to eject cleaning water toward the rear surface 31 of the toilet seat 3. The cleaning device 5 further has a water supply passage 17 that connects the first cleaning nozzle 60a and the second cleaning nozzle 60b to a water supply source.

[0116] In the toilet seat device 1 of the first embodiment, water from a water supply source can be supplied to the first cleaning nozzle 60a and the second cleaning nozzle 60b through the water supply passage 17. In the toilet seat device 1 of the first embodiment, cleaning water can be discharged from the first cleaning nozzle 60a and the second cleaning nozzle 60b onto the seat surface 30 and the back surface 31 of the toilet seat 3. Therefore, in the toilet seat device 1 of the first embodiment, the seat surface 30 and the back surface 31 of the toilet seat 3 can be cleaned.

[0117] As in the embodiment and its modified example described above, the toilet seat device 1 of the second aspect additionally includes the following configuration in addition to the configuration of the first aspect.

[0118] That is, in the toilet seat device 1 of the second embodiment, the water supply passage 17 is composed of a first water supply passage 17a and a second water supply passage 17b. The first water supply passage 17a and the second water supply passage 17b are not connected to each other. The first washing nozzle 60a is connected to the first water supply passage 17a. The second washing nozzle 60b is connected to the second water supply passage 17b.

[0119] In the toilet seat device 1 of the second embodiment, the water pressure, temperature, type, or combination thereof of the flowing water can be changed between the first water supply passage 17a and the second water supply passage 17b. Therefore, in the toilet seat device 1 of the second embodiment, the cleaning power of the cleaning water discharged from the first cleaning nozzle 60a and the second cleaning nozzle 60b can be changed between them. Therefore, in the toilet seat device 1 of the second embodiment, cleaning water with high cleaning power can be discharged from the second cleaning nozzle 60b to the back surface 31 of the toilet seat 3, which is prone to adhesion of feces and urine that have splashed off the surface of the bowl 20, and cleaning suitable for the degree of dirt can be performed.

[0120] As in the embodiment and its modified example described above, the toilet seat device 1 of the third aspect additionally includes the following configuration in addition to the configuration of the first or second aspect.

[0121] That is, in the toilet seat device 1 of the third embodiment, the cleaning device 5 further includes a drying nozzle 70 configured to blow air onto the toilet seat 3.

[0122] In the toilet seat device 1 of the third embodiment, the seat surface 30 and the back surface 31 of the toilet seat 3 can be cleaned with cleaning water from the first cleaning nozzle 60a and the second cleaning nozzle 60b, and the toilet seat 3 can be dried with air from the drying nozzle 70. Therefore, in the toilet seat device 1 of the third embodiment, cleaning water remaining on the seat surface 30 and the back surface 31 of the toilet seat 3 can be removed.

[0123] As in the above-described embodiment and its modified example, the toilet seat device 1 of the fourth aspect additionally includes the following configuration in addition to the configuration of any one of the first to third aspects.

[0124] That is, in the toilet seat device 1 of the fourth embodiment, the cleaning device 5 further includes a movable part 10 that moves in the circumferential direction of the toilet seat 3. The movable part 10 is provided with a first cleaning nozzle 60a and a second cleaning nozzle 60b.
