The toilet seat device 1 includes a toilet seat 3, a toilet cover 4, and a cleaning device 5 for cleaning the toilet seat 3. The cleaning device 5 includes a first cleaning nozzle 60a configured to spray cleaning water toward a seat surface 30 of the toilet seat 3, and a second cleaning nozzle 60b configured to spray cleaning water toward a back surface 31 of the toilet seat 3. The opening area of ​​the end of the second cleaning nozzle 60b is smaller than the opening area of ​​the end of the first cleaning nozzle 60a.

[0030] In the toilet seat device 1 of one embodiment having the above-mentioned structure, the seat surface 30 and the back surface 31 of the toilet seat 3 can be cleaned by the cleaning water sprayed from the first cleaning nozzle 60a and the second cleaning nozzle 60b. In addition, in the toilet seat device 1 of one embodiment, the opening area of ​​the end of the second cleaning nozzle 60b is smaller than the opening area of ​​the end of the first cleaning nozzle 60a, so it is easy to increase the water pressure of the cleaning water relative to the back surface 31 of the toilet seat 3 compared with the water pressure of the cleaning water relative to the seat surface 30 of the toilet seat 3. As a result, in the toilet seat device 1 of one embodiment, the cleaning water can be sprayed with a higher water pressure to the back surface 31 where dirt that is difficult to fall off is easy to adhere, and cleaning can be performed with cleaning water with high cleaning ability. Therefore, in the toilet seat device 1 of one embodiment, the seat surface 30 and the back surface 31 of the toilet seat 3 can be cleaned appropriately according to the dirt.

[0031] Alternatively, a toilet seat device 1 according to an embodiment is mounted on a toilet body 2 having a toilet bowl 20. The toilet seat device 1 includes a toilet seat 3, a toilet cover 4, and a cleaning device 5 for cleaning the toilet seat 3. The cleaning device 5 includes: a first cleaning nozzle 60a configured to spray cleaning water toward a seat surface 30 of the toilet seat 3; and a second cleaning nozzle 60b configured to spray cleaning water toward a back surface 31 of the toilet seat 3. The cleaning device 5 further includes: a first water supply path 17a that connects the first cleaning nozzle 60a to a water supply source; and a second water supply path 17b that connects the second cleaning nozzle 60b to a water supply source.

[0032] In the toilet seat device 1 of one embodiment having the above-mentioned structure, the seat surface 30 and the back surface 31 of the toilet seat 3 can be cleaned by the cleaning water sprayed from the first cleaning nozzle 60a and the second cleaning nozzle 60b. In addition, in the toilet seat device 1 of one embodiment, by changing the water pressure, temperature, type, or combination of the water flowing in the first water supply path 17a and the water flowing in the second water supply path 17b, the cleaning power of the cleaning water sprayed to the seat surface 30 and the back surface 31 of the toilet seat 3 can be changed. Therefore, in the toilet seat device 1 of one embodiment, the cleaning water with high cleaning power can be sprayed to the back surface 31 where dirt that is difficult to fall off is easy to adhere. Therefore, in the toilet seat device 1 of one embodiment, the seat surface 30 and the back surface 31 of the toilet seat 3 can be cleaned appropriately according to the dirt situation.

[0033] Furthermore, the toilet apparatus 100 according to one embodiment includes: a toilet body 2 having a toilet bowl 20 ; and the toilet seat apparatus 1 mounted on the toilet body 2 .

[0053] (Toilet Seat 3)

[0054] Figure 7 FIG. 1 is a partially cutaway top view schematically showing the movement of the cleaning device 5 according to one embodiment. Figure 1 and Figure 7 As shown, the toilet seat 3 is annular in plan view. The toilet seat 3 has a seat surface 30 for a user to sit on and a back surface 31 facing the opposite side of 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.

[0055] The rear end of the toilet seat 3 is connected to the mounting portion 15 (see FIG. 1 ) mounted in the mounting hole 211 of the toilet body 2 in a swingable manner. Figure 3 ) is connected. The toilet seat 3 can swing between a lying position in which the back surface 31 of the toilet seat 3 is along the upper end surface (i.e., the upper surface 210) of the toilet body 2 and an upright position in which the toilet seat 3 is upright relative to the upper end surface of the toilet body 2. The legs 32 of the toilet seat 3 abut against the upper end surface of the toilet body 2. Thus, a gap is formed between the back surface 31 of the toilet seat 3 and the upper end surface of the toilet body 2 when in the lying position.

[0056] (Toilet lid 4)

[0057] like Figure 2 and Figure 3 As shown, the toilet cover 4 comprises: a toilet cover body 40, which covers the seat surface 30 of the toilet seat 3; and a toilet cover side wall 41, which extends from the outer peripheral edge of the toilet cover body 40 and covers the outer peripheral surface of the toilet seat 3. The toilet cover body 40 is plate-shaped. Similarly, the toilet cover side wall 41 is plate-shaped. In the thickness direction of the toilet cover body 40 (i.e., Figure 2When viewed in the up-down direction in the toilet cover body 40, the toilet cover body 40 is semi-elliptical. When viewed in the thickness direction of the toilet cover body 40, the toilet cover side wall 41 is semi-elliptical.

[0058] The rear end of the toilet cover 4 is swingably connected to the mounting portion 15. The toilet cover 4 can swing between a closed position where the toilet cover body 40 is along the upper end surface of the toilet body 2 and an open position where the toilet cover body 40 stands relative to the upper end surface of the toilet body 2.

[0059] A sealing portion 16 is provided at the outer peripheral edge of the toilet cover 4 (i.e., the lower end of the toilet cover side wall 41), and the sealing portion 16 is configured to close the gap between the toilet body 2. Like the toilet cover side wall 41, the sealing portion 16 is also in a semi-elliptical ring shape. In detail, the sealing portion 16 is provided all around the lower end of the toilet cover side wall 41. The sealing portion 16 is, for example, a rubber gasket. In addition, the sealing portion 16 may be made of resin, or may be a labyrinth structure provided on the lower surface of the toilet cover side wall 41.

[0060] When the toilet lid 4 is in the closed position, the sealing portion 16 contacts the upper end surface of the toilet body 2, and the gap between the toilet lid side wall 41 and the upper end surface of the toilet body 2 is closed. Thus, water and air can be prevented from leaking from between the toilet lid side wall 41 of the toilet lid 4 and the upper end surface of the toilet body 2.

[0061] A guide rail 42 is provided on the back of the toilet lid body 40 along the circumference of the toilet seat 3. The guide rail 42 is composed of an inner guide rail 420, an outer guide rail 421, and a middle guide rail 422, which are semi-elliptical rings in a plan view. The middle guide rail 422 is provided with a rack and a groove recessed upward (i.e., toward the toilet lid body 40) over the entire length of the circumference.

[0062] like Figure 7 As shown in FIG. 1 , a first stopper 43 and a second stopper 44 are provided on the back of the toilet cover body 40. The first stopper 43 is provided in a manner opposite to the end surface of the first end of the guide rail 42 in the longitudinal direction (for example, one end of the guide rail 42). The second stopper 44 is provided in a manner opposite to the end surface of the second end of the guide rail 42 in the longitudinal direction (for example, the other end of the guide rail 42). Figure 7 The guide rail 42 is omitted in the figure.

[0063] The first stopper 43 and the second stopper 44 are flat plates arranged at right angles to the toilet cover 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 a direction slightly inclined to the left relative to the front-rear direction. The thickness direction of the second stopper 44 is a direction slightly inclined to the right relative to the front-rear direction.

[0064] The first stopper 43 and the second stopper 44 are located at the same position in the front-rear direction. A first buffer member 45a is mounted on the surface (i.e., the front surface) of the first stopper 43 that faces the guide rail 42. A second buffer member 45b is mounted on the surface (i.e., the front surface) of the second stopper 44 that faces the guide rail 42. The first buffer member 45a and the second buffer member 45b are each in a sheet shape, for example, made of rubber.

[0066] The air blower 8 is mounted on the surface of the toilet lid body 40 (ie, the surface opposite to the toilet seat 3). The toilet lid body 40 has a through hole 400 at the center thereof through which a part of the air blower tube 14 connected to the air blower 8 passes.

[0067] (Air supply pipe 14)

[0068] The air supply duct 14 includes a fixed duct 140 attached to the front surface of the toilet lid body 40 and a movable duct 141 communicating with the fixed duct 140 and disposed on the back surface of the toilet lid body 40 .

[0069] The movable tube 141 is a tube that can be extended and retracted. One end (more specifically, the upstream end) of the movable tube 141 is connected to the fixed tube 140. The other end (more specifically, the downstream end) of the movable tube 141 is connected to the movable part 10 via the switching mechanism 9. Figure 3 As shown, as the movable portion 10 moves in the circumferential direction of the toilet seat 3, the movable pipe 141 automatically expands and contracts while rotating around the insertion hole 400.

[0070] like Figure 3 As shown, in one embodiment, the movable pipe 141 has a first pipe portion 142 connected to the fixed pipe 140, and a second pipe portion 143 connected to the movable portion 10 via the switching mechanism 9. The inner diameter of the second pipe portion 143 is slightly larger than the outer diameter of the first pipe portion 142. A portion of the first pipe portion 142 is slidably embedded in the inner side of the second pipe portion 143. Thus, the movable pipe 141 can be extended and retracted. In addition, the movable pipe 141 only needs to be able to be extended and retracted. The movable pipe 141 can also be, for example, a corrugated pipe.

[0071] (Movable part 10)

[0072] Figure 1The movable part 10 shown is attached to the toilet cover body 40 of the toilet cover 4 so as to move along the circumferential direction of the toilet seat 3. The movable part 10 is guided by the guide rail 42 to move, thereby reciprocating in the circumferential direction of the toilet seat 3. The movable part 10 can move between a first movable position relative to a part of the circumference of the toilet seat 3 and a second movable position relative to another part of the circumference of the toilet seat 3. In one embodiment, the part of the circumference of the toilet seat 3 and the other part are the left and right parts of the rear part 330 of the toilet seat 3 sandwiching the central opening 33.

[0073] The first movable position is the position of the movable part 10 when the first end in the longitudinal direction of the guide rail 42 abuts against the first stopper 43. Figure 7 In FIG. 1 , the first movable position is the position where the movable portion 10 on the left side indicated by the two-dot chain line is located.

[0074] The second movable position is the position of the movable part 10 when the second end in the longitudinal direction of the guide rail 42 abuts against the second stopper 44. Figure 7 In FIG. 1 , the second movable position is the position of the right movable portion 10 indicated by the two-dot chain line. The position of the first movable position in the front-rear direction and the position of the second movable position in the front-rear direction are the same.

[0075] Figure 4 FIG. 1 is a perspective view showing a part of the cleaning device 5 provided in the toilet seat device 1 according to one embodiment. Figure 4 and Figure 7 As shown, the movable part 10 has a roller 101 that rolls on the guide rail 42. The roller 101 is composed of an inner roller 102 that rolls on the inner guide rail 420, an outer roller 103 that rolls on the outer guide rail 421, and an intermediate roller 104 that rolls in the groove of the intermediate guide rail 422. The movable part 10 also has a pinion 105 that meshes with a rack provided on the intermediate guide rail 422, and a motor 106 that rotates the pinion 105.

[0076] By the rotation of the motor 106, the pinion 105 rotates while meshing with the rack of the middle guide rail 422, and the roller 101 rolls on the guide rail 42, so that the movable part 10 moves in the circumferential direction of the toilet seat 3. At this time, the inner roller 102, the outer roller 103, and the middle roller 104 roll on the inner guide rail 420, the outer guide rail 421, and the middle guide rail 422, thereby suppressing the tilt of the movable part 10 relative to the horizontal direction. As a result, the relative positional relationship between the movable part 10 and the toilet seat 3 that is moved is substantially constant at any position in the circumferential direction of the toilet seat 3.

[0077] like Figure 4As shown, the movable part 10 includes a driving part 107, a washing 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 includes a roller 101, a pinion 105, and a motor 106.

[0078] The washing water supply unit 6 and the air supply unit 7 are arranged in the circumferential direction of the toilet seat 3 (ie, Figure 4 The two axes are arranged in the left and right direction.

[0080] like Figure 4 and Figure 5 As shown, the washing water supply part 6 includes: a main body 61 extending along a portion of the circumference of the seat surface 30 of the toilet seat 3; and a first arm 62 extending downward from one end of the main body 61 in the length direction. The washing water supply part 6 also includes a second arm 63 extending downward from the other end of the main body 61 in the length direction. The first arm 62 is located outside the outer peripheral edge of the toilet seat 3. The second arm 63 is located inside the inner peripheral edge of the toilet seat 3. The lower end of the first arm 62 is located above the upper end surface (i.e., the upper surface 210) of the toilet body 2. The length of the second arm 63 protruding from the main body 61 is longer than the length of the first arm 62 protruding from the main body 61. The lower end of the second arm 63 is located below the upper end surface (i.e., the upper surface 210) of the toilet body 2.

[0081] The main body 61 is provided with a water supply port 64 connected to the water supply pipe 12. In one embodiment, the water supply port 64 is composed of a first water supply port 64a connected to the first water supply pipe 12a and a second water supply port 64b connected to the second water supply pipe 12b.

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 different joints.

[0082] like Figure 5 As shown, the washing water supply unit 6 is provided with a first water passage 11a communicating with the first water supply port 64a and a second water passage 11b communicating with the second water supply port 64b. The first water passage 11a and the second water passage 11b are not connected to each other. That is, the first water passage 11a and the second water passage 11b are different water passages.

[0083] (Cleaning nozzle 60)

[0084] The cleaning nozzle 60 includes: a first cleaning nozzle 60a configured to spray cleaning water toward the seat surface 30 of the toilet seat 3; and a second cleaning nozzle 60b configured to spray cleaning water toward the back surface 31 of the toilet seat 3. The cleaning nozzle 60 also includes: a toilet cover cleaning nozzle 60c configured to spray cleaning water toward the inner peripheral surface of the toilet cover side wall 41 of the toilet cover 4; and a toilet bowl cleaning nozzle 60d configured to spray cleaning water toward the upper end of the toilet bowl 20. The cleaning water is not limited to water, and may also be warm water, water containing foam, sterilizing water or detergent. In addition, in order to deal with scale, the cleaning water may also be water from which metal components are removed by a water softener.

[0085] The first cleaning nozzle 60a is provided at the inner corner portion formed by the first arm portion 62 and the main body portion 61. Therefore, cleaning water is sprayed from the first cleaning nozzle 60a toward the inner peripheral side of the toilet seat 3 toward the seat surface 30 of the toilet seat 3. The seat surface 30 of the toilet seat 3 is cleaned by the cleaning water flowing from the outer peripheral side of the toilet seat 3 toward the inner peripheral side.

[0086] The second cleaning nozzle 60b is provided on the inner surface of the lower end of the first arm portion 62 (i.e., the surface opposite to the toilet seat 3). Therefore, cleaning water is sprayed from the second cleaning nozzle 60b toward the inner peripheral side of the toilet seat 3 toward the back side 31 of the toilet seat 3. In one embodiment, cleaning water is also sprayed from the second cleaning nozzle 60b toward the upper end surface (i.e., the upper surface 210) of the toilet body 2 opposite to the back side 31 of the toilet seat 3. Thus, the back side 31 of the toilet seat 3 and the upper end surface (i.e., the upper surface 210) of the toilet body 2 opposite thereto are cleaned by the cleaning water toward the inner peripheral side of the toilet seat 3.

[0087] The toilet lid cleaning nozzle 60c is provided on the outer surface of the upper portion of the first arm portion 62 (ie, the surface facing the toilet lid side wall 41). The first cleaning nozzle 60a, the toilet lid cleaning nozzle 60c, and the second cleaning nozzle 60b are arranged in the vertical direction in this order.

[0088] The toilet bowl cleaning nozzle 60d is provided on the outer surface of the lower end portion of the second arm portion 63 (i.e., the surface facing the toilet seat 3). Figure 1 As shown, two toilet bowl cleaning nozzles 60d are provided on the second arm portion 63. Figure 5 As shown, the two toilet bowl cleaning nozzles 60d are opened obliquely downward and toward the inner peripheral surface of the upper end of the toilet bowl 20. Figure 1 As shown, the openings of the two toilet bowl cleaning nozzles 60d are oriented approximately 120 degrees apart from each other when viewed from above.

[0089] The first cleaning nozzle 60a and the toilet lid cleaning nozzle 60c are connected to the first water path 11a, and the second cleaning nozzle 60b and the two toilet bowl cleaning nozzles 60d are connected to the second water path 11b.

[0090] 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. Therefore, the cleaning water can be sprayed more vigorously from the second cleaning nozzle 60b than from the first cleaning nozzle 60a.

[0091] In one embodiment, there is a first water path 11a for supplying washing water to the first washing nozzle 60a and the toilet lid washing nozzle 60c, and a second water path 11b for supplying washing water to the second washing nozzle 60b and the toilet bowl washing nozzle 60d. Therefore, the water pressure, temperature, type, or a combination of these washing water can be changed in the first water path 11a and the second water path 11b, thereby changing the washing ability of the washing water. Therefore, it is also possible to supply washing water with high washing ability from the second washing nozzle 60b and the toilet bowl washing nozzle 60d to the upper end of the toilet bowl 20 and the back side 31 of the toilet seat 3, where urine and feces splashed on the surface of the toilet bowl 20 are easily attached.

[0092] (Air supply unit 7)

[0093] like Figure 4 and Figure 6 As shown, the air supply unit 7 includes a main body 71 extending along a portion of the circumference of the seat surface 30 of the toilet seat 3, and an arm 72 extending from one end of the main body 71 in the longitudinal direction. The arm 72 is located outside the outer peripheral edge of the toilet seat 3. The arm 72 is provided with a drying nozzle 70 for spraying air toward the toilet seat 3.

[0094] (Drying nozzle 70)

[0095] 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 spray air toward the seat surface 30 of the toilet seat 3. The second drying nozzle 70b is configured to spray air toward the back surface 31 of the toilet seat 3. The toilet lid drying nozzle 70c is configured to spray air toward the toilet lid side wall 41 of the toilet lid 4. That is, in one embodiment, the drying nozzle 70 sprays air toward the toilet seat 3 and its surroundings.

[0096] The switching mechanism 9 is installed on the main body 71. Figure 6 , Fig. 9A as well as Fig. 9B As shown in FIG. 1 , the main body 71 is provided with a first connection port 73 a and a second connection port 73 b. One connection port selected from the first connection port 73 a and the second connection port 73 b communicates with the air supply passage 18 via the switching mechanism 9 .

[0097] like Figure 6As shown, 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 different air passages.

[0098] The first air passage 13a is connected to the first drying nozzle 70a. The second air passage 13b is connected to the second drying nozzle 70b and the toilet lid drying nozzle 70c. That is, the toilet lid drying nozzle 70c is connected to the air passage (i.e.,

[0099] The second air passage 13b) is connected.

[0100] The first drying nozzle 70a is provided at the upper end portion of the arm portion 72. Therefore, on the seat surface 30 of the toilet seat 3, air is ejected toward the inner peripheral side of the toilet seat 3 from the first drying nozzle 70a.

[0101] The second drying nozzle 70b is provided at the lower end of the arm 72. Therefore, air is ejected from the second drying nozzle 70b toward the inner circumference of the toilet seat 3 toward the back surface 31 of the toilet seat 3. In one embodiment, air is also ejected from the second drying nozzle 70b toward the upper end surface (i.e., the upper surface 210) of the toilet body 2 opposite to the back surface 31 of the toilet seat 3. Therefore, air is ejected from the second drying nozzle 70b toward the inner circumference 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 opposite thereto.

[0102] The toilet lid drying nozzle 70c is provided at the middle part of the arm part 72 in the vertical direction. 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 arranged in the vertical direction in this order.

[0103] The first drying nozzle 70a is arranged in the left-right direction relative to the first cleaning nozzle 60a. The position of the first drying nozzle 70a in the up-down direction is the same as the position of the first cleaning nozzle 60a in the up-down direction. The toilet cover drying nozzle 70c is arranged in the left-right direction relative to the toilet cover cleaning nozzle 60c. The position of the toilet cover drying nozzle 70c in the up-down direction is the same as the position of the toilet cover cleaning nozzle 60c in the up-down direction. The second drying nozzle 70b is arranged in the left-right direction relative to the second cleaning nozzle 60b. The position of the second drying nozzle 70b in the up-down direction is the same as the position of the second cleaning nozzle 60b in the up-down direction.

[0104] Therefore, when the movable part 10 moves, the air from the first drying nozzle 70a and the washing water from the first washing nozzle 60a are ejected to substantially the same position relative to the seat surface 30 of the toilet seat 3. Similarly, the air from the toilet cover drying nozzle 70c and the washing water from the toilet cover washing nozzle 60c are ejected to substantially the same position relative to the inner peripheral surface of the toilet cover side wall 41. Similarly, the air from the second drying nozzle 70b and the washing water from the second washing nozzle 60b are ejected to substantially the same position relative to the back surface 31 of the toilet seat 3.

[0105] like Figure 4 As shown, two openings 74 are arranged vertically at the end of the second drying nozzle 70b. Therefore, the air ejected from the second drying nozzle 70b easily contacts the back surface 31 of the toilet seat 3 and the upper end surface (ie, upper surface 210) of the toilet body 2.

[0106] (Switching mechanism 9)

[0107] Figure 4 and Figure 6 The switching mechanism 9 shown is configured to switch the connection state between a first connection state in which the first drying nozzle 70a of the first drying nozzle 70a and the second drying nozzle 70b are connected to the air supply device 8, and a second connection state in which the second drying nozzle 70a of the first drying nozzle 70b and the second drying nozzle 70b are connected to the air supply device 8. The switching mechanism 9 includes a switch 90, which contacts and is pressed by a portion surrounding 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 also includes a switching part 91 (refer to Figure 8 ), the switching unit 91 is configured to switch the connection state from the first connection state to the second connection state, or from the second connection state to the first connection state when the switch 90 is pressed.

[0108] Figure 8 1 is a perspective view showing a switching unit 91 of a switching mechanism 9 included in a cleaning device 5 according to an embodiment. Figure 6 and Figure 8 As shown, the switch part 91 has an air passage 910 inside. The air passage 910 includes a first end 911 connected to the air supply device 8 and a second end 912 connected to the first drying nozzle 70a or the second drying nozzle 70b. The switch part 91 moves between a first connection position where the second end 912 is connected to the first drying nozzle 70a and a second connection position where the second end 912 is connected to the second drying nozzle 70b.

[0109] The switching portion 91 rotates when the switch 90 is pressed, and switches from the first connection position to the second connection position, or switches from the second connection position to the first connection position. In detail, the switching portion 91 rotates when the first end in the length direction of the switch 90 is pressed, and switches from the first connection position to the second connection position. And, when the second end in the length direction of the switch 90 (i.e., the end on the opposite side to the first end) is pressed, the switching portion 91 moves from the second connection position to the first connection position. This will be described in detail later.

[0110] like Figure 4 As shown, the switching mechanism 9 further includes: a connecting member 92 that connects the switch 90 and the switching unit 91; and a housing 93 that holds the switching unit 91 rotatably.

[0111] In one embodiment, the switch 90 is a rod-shaped member supported in a movable manner by the driving unit 107 of the movable unit 10. The switch 90 is disposed in the circumferential direction of the toilet seat 3 (ie, Figure 4 The switch 90 is longer than the movable part 10 in the left-right direction (in the left-right direction), and both ends in the length direction protrude in the circumferential direction of the toilet seat 3 from the movable part 10. The switch 90 can move in the length direction. When the movable part 10 moves between the first movable position and the second movable position, the switch 90 moves in the length direction by contacting the first stopper 43 or the second stopper 44.

[0112] A connecting member 92 is fixed to a portion in the longitudinal direction of the switch 90. The connecting member 92 moves in the same direction as the switch 90 as the switch 90 moves.

[0113] like Figure 8 As shown, the outer shape of the switching part 91 is a cylindrical shape having a central axis parallel to the up-down direction. The switching part 91 has an air passage 910 inside. A first end 911 of the air passage 910 opens at the center of the upper surface of the switching part 91. A second end 912 of the air passage 910 opens at a part of the outer peripheral surface of the switching part 91. A pin-shaped rotating operation part 913 protrudes upward from a part of the upper surface of the switching part 91.

[0114] like Figure 4 As shown, in one embodiment, the housing 93 is formed by combining two upper and lower divided bodies. Fig. 9A It is a plan view showing a state of switching by the switching mechanism 9 according to one embodiment. Fig. 9B 1 is a top view showing a switching mechanism 9 according to an embodiment of the present invention. Figure 4 , Fig. 9A as well as Fig. 9BAs shown, the housing 93 is provided with: a cylindrical connection port 930, which is connected to the air supply pipe 14; and an arc-shaped hole 931, which is passed through the rotating operation part 913. The housing 93 is also provided with: a first communication passage 932, which connects the second end 912 with the first connection port 73a; and a second communication passage 933, which connects 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 different air passages.

[0115] The switch unit 91 is rotatably arranged in the housing 93. The first end 911 of the air passage 910 of the switch unit 91 is connected to the connection port 930. The rotation operation unit 913 of the switch unit 91 protrudes upward from the arc-shaped hole 931 of the housing 93. The rotation operation unit 913 is connected to the switch 90 via the connecting member 92. As the rod-shaped switch 90 moves forward and backward in the length direction thereof, the rotation operation unit 913 moves along the circumference of the arc-shaped hole 931. Thus, the switch unit 91 switches between a first connection position in which the second end 912 of the air passage 910 is connected to the first connection passage 932 and a second connection position in which the second end 912 is connected to the second connection passage 933.

[0116] In one embodiment, when the movable part 10 reaches the first movable position or the second movable position, the first end or the second end (the end opposite to the first end) of the switch 90 in the longitudinal direction abuts against the first stopper 43 or the second stopper 44, and the switch 90 moves in the longitudinal direction thereof. As a result, the switching part 91 rotates, the second end 912 of the air passage 910 communicates with either the first air passage 13a or the second air passage 13b, and the air from the air supply device 8 is supplied to either the first drying nozzle 70a or the second drying nozzle 70b.

[0117] The toilet seat device 1 further includes a control unit that controls the movable portion 10, the washing water supply portion 6, and the air supply portion 7. The control unit is a device that mainly includes a computer system such as a microcomputer. The movement of the movable portion 10, the supply of washing water by the washing water supply portion 6, and the supply of air by the air supply portion 7 are controlled by the control unit. Thus, in the toilet seat device 1 of one embodiment, the toilet seat 3 and its surroundings can be automatically cleaned.

[0118] like Figure 1 as well as Figure 7 As shown, the toilet seat device 1 further includes a cover 19 attached to the toilet cover body 40 of the toilet cover 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 to prevent them from being exposed.

[0119] like Figure 1As shown, 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. Furthermore, a first joint 120a and a second joint 120b of the toilet seat device 1 are connected to a water supply source, respectively.

[0120] 2-3. Operation of the toilet seat device

[0121] The toilet seat apparatus 1 and the toilet apparatus 100 according to one embodiment operate, for example, as follows.

[0122] When the user finishes using the toilet apparatus 100 and closes the toilet lid 4 automatically or manually, the cleaning device 5 starts cleaning the toilet seat 3 .

[0123] First, the movable part 10 (i.e., Figure 7 The movable part 10 on the left side of the toilet seat 3 moves toward the second movable position along the circumferential direction of the toilet seat 3. At this time, washing water is supplied from the water supply source to the washing water supply part 6 via the first water supply pipe 12a and the second water supply pipe 12b. As a result, washing water is sprayed from the first washing nozzle 60a, the second washing nozzle 60b, the toilet cover washing nozzle 60c, and the toilet bowl washing 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 cover side wall 41, and the upper end of the toilet bowl 20 are washed by washing water.

[0124] When the movable part 10 reaches the second movable position, the supply of washing water to the washing water supply part 6 is stopped. Fig. 9B As shown, one end of the switch 90 in the longitudinal direction abuts against 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 connecting position connected to the second connecting passage 933. In addition, the air passage 910 is connected to the second connecting port 73b and the second air passage 13b. Thus, the air supply device 8 is connected to the second drying nozzle 70b and the toilet lid drying nozzle 70c via the air supply pipe 14 and the second air passage 13b. In addition, at this time, the second end 912 of the air passage 910 of the switching part 91 is not connected to the first connecting passage 932, and the air passage 910 is not connected to the first connecting port 73a and the first air passage 13a. Therefore, the air supply device 8 is not connected to the first drying nozzle 70a.

[0125] Next, the movable part 10 located at the second movable position moves toward the first movable position along the circumferential direction of the toilet seat 3. At this time, air is supplied from the air supply device 8 to the air supply pipe 14 and the second air passage 13b, and air is ejected from the second drying nozzle 70b and the toilet cover drying nozzle 70c. Thus, 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 opposite thereto are dried, and the inner peripheral surface of the toilet cover side wall 41 is dried. In addition, at this time, air is not ejected from the first drying nozzle 70a.

[0126] When the movable part 10 reaches the first movable position, Fig. 9A As shown, the other end of the switch 90 in the longitudinal direction abuts against 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 connecting position connected to the first connecting passage 932. In addition, the air passage 910 is connected to the first connecting port 73a and the first air passage 13a. Thus, the air supply device 8 is connected to the first drying nozzle 70a via the air supply pipe 14 and the first air passage 13a. In addition, at this time, the second end 912 of the air passage 910 of the switching part 91 is not connected to the second connecting passage 933, and the air passage 910 is not connected to the second connecting port 73b and the second air passage 13b. Therefore, the air supply device 8 is not connected to the second drying nozzle 70b and the toilet lid drying nozzle 70c.

[0127] Next, the movable part 10 located at the first movable position moves toward the second movable position along the circumferential direction of the toilet seat 3. At this time, air is supplied from the air supply device 8 to the air supply pipe 14 and the first air passage 13a, and air is ejected from the first drying nozzle 70a. Thus, the seat surface 30 of the toilet seat 3 is dried. In addition, at this time, air is not ejected from the second drying nozzle 70b and the toilet lid drying nozzle 70c.

[0128] When the movable part 10 reaches the second movable position, the air supply through the air supply device 8 is stopped, and the cleaning operation of the toilet seat 3 is completed. Fig. 9B As shown, one end of the switch 90 in the longitudinal direction contacts 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 air supply device 8 via the air supply pipe 14 and the second air passage 13b.

[0129] In addition, the spraying of the washing water from the first washing nozzle 60a and the toilet lid washing nozzle 60c and the spraying of the washing water from the second washing nozzle 60b and the toilet bowl washing nozzle 60d can also be staggered. For example, when the movable part 10 moves from the first movable position to the second movable position, the washing water can be sprayed only from the second washing nozzle 60b and the toilet bowl washing nozzle 60d. Moreover, when the movable part 10 moves from the second movable position to the first movable position, the washing water can be sprayed only from the first washing nozzle 60a and the toilet lid washing nozzle 60c. In this case, even if the washing water sprayed 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 toilet bowl 20 is scattered toward the seat surface 30 of the toilet seat 3 or the inner peripheral surface of the toilet lid side wall 41, flushing can be performed.

[0130] 2-4. Effects

[0131] In the toilet seat device 1 of the embodiment described above, the opening area of ​​the end of the second cleaning nozzle 60b is smaller than the opening area of ​​the end of the first cleaning nozzle 60a. Therefore, in the toilet seat device 1 of the embodiment, it is possible to spray cleaning water with high water pressure and high cleaning power to the back surface 31 of the toilet seat 3 where dirt that is difficult to fall off, such as urine and fecal dirt splashed on the surface of the toilet bowl 20, is easily attached. Therefore, in the toilet seat device 1 of the embodiment, it is possible to clean the seat surface 30 and the back surface 31 of the toilet seat 3 respectively according to the dirt situation.

[0132] In the toilet seat device 1 of one embodiment, the first water supply path 17a connecting the first cleaning nozzle 60a to the water supply source and the second water supply path 17b connecting the second cleaning nozzle 60b to the water supply source are different water paths. Therefore, in the toilet seat device 1 of one embodiment, by changing the water pressure, temperature, type or combination of the water flowing in the first water supply path 17a and the second water supply path 17b, the cleaning power of the cleaning water sprayed to the seat surface 30 and the back surface 31 of the toilet seat 3 can be changed. Thus, in the toilet seat device 1 of one embodiment, the cleaning water with the cleaning power suitable for the contamination of the cleaning part can be supplied to the first cleaning nozzle 60a and the second cleaning nozzle 60b respectively. Therefore, in the toilet seat device 1 of one embodiment, it is easy to clean the seat surface 30 and the back surface 31 of the toilet seat 3 respectively according to the dirt situation.

[0133] In the toilet seat device 1 of one embodiment, the toilet cover cleaning nozzle 60c can spray cleaning water with the same cleaning power as the first cleaning nozzle 60a, and the toilet bowl cleaning nozzle 60d can spray cleaning water with the same cleaning power as the second cleaning nozzle 60b. Therefore, in the toilet seat device 1 of one embodiment, it is also easy to clean the inner peripheral surface of the toilet cover side wall 41 and the upper end of the toilet bowl 20 respectively according to the dirt situation.

[0134] In the toilet seat device 1 of one embodiment, the second cleaning nozzle 60b sprays cleaning water toward the inner peripheral side of the toilet seat 3. Therefore, in the toilet seat device 1 of one embodiment, even if the water pressure of the cleaning water sprayed from the second cleaning nozzle 60b is increased, it is possible to suppress the cleaning water from being discharged to the outside of the toilet seat 3, that is, the outside of the lid 4.

[0135] In the toilet seat device 1 of one embodiment, a sealing portion 16 is provided on the outer periphery of the toilet cover 4 (specifically, the lower end of the toilet cover side wall 41) to close the gap between the toilet cover side wall 41 and the toilet body 2. Therefore, in the toilet seat device 1 of one embodiment, even if the water pressure of the washing water sprayed from the second washing nozzle 60b is increased, it is possible to suppress the washing water from being discharged to the outside of the toilet seat 3, that is, the outside of the cover 4.

[0136] In the toilet seat device 1 of one embodiment, the seat surface 30, the back surface 31 of the toilet seat 3, and the inner peripheral surface of the toilet cover side wall 41 can be dried by the wind from the first drying nozzle 70a, the second drying nozzle 70b, and the toilet cover drying nozzle 70c. Therefore, in the toilet seat device 1 of one embodiment, it is possible to suppress the generation of water marks due to evaporation in a state where washing water remains on the seat surface 30, the back surface 31, and the inner peripheral surface of the toilet cover side wall 41 of the toilet seat 3.

[0137] In the toilet seat device 1 of one embodiment, the back surface 31 of the toilet seat 3 is located at a position separated from 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 back surface 31 of the toilet seat 3 and the upper end surface of the toilet body 2 can be cleaned together by the cleaning water from the second cleaning nozzle 60b.

[0138] 3. Modifications

[0139] Next, a description will be given of modifications of the above-mentioned toilet seat apparatus 1 and toilet apparatus 100. The modifications described below can be combined as appropriate.

[0140] The first water supply passage 17a and the second water supply passage 17b may be one water supply passage connected to each other.

[0141] The water flowing in the first water supply passage 17a and the water flowing in the second water supply passage 17b may be water having the same cleaning power (i.e., the same water pressure, water temperature, type, or a combination thereof). In this case, since the opening areas at the ends of the first cleaning nozzle 60a and the second cleaning nozzle 60b are different from each other, it is possible to spray cleaning water having cleaning power suitable for each.

[0142] The opening area of ​​the end of the second cleaning nozzle 60b may be larger than or equal to the opening area of ​​the end of the first cleaning nozzle 60a. In this case, water having a higher cleaning ability than the water flowing in the first water supply passage 17a flows in the second water supply passage 17b.

[0143] The cleaning device 5 only needs to have at least the first cleaning nozzle 60a and the second cleaning nozzle 60b, and may not have the toilet lid cleaning nozzle 60c. The cleaning device 5 may not have the toilet bowl cleaning nozzle 60d that sprays cleaning water toward the upper end of the toilet bowl 20. In this case, the cleaning water supply unit 6 may not have the second arm 63.

[0144] The toilet lid cleaning nozzle 60c may be connected to a dedicated water supply path instead of the first water supply path 17a. Similarly, the toilet bowl cleaning nozzle 60d may be connected to a dedicated water supply path instead of the second water supply path 17b.

[0145] The second cleaning nozzle 60b may not be opened toward the inner peripheral side of the toilet seat 3. The second cleaning nozzle 60b may be opened toward the outer peripheral side of the toilet seat 3. In this case, in the toilet apparatus 100 of one embodiment, the sealing portion 16 can also prevent the cleaning water sprayed toward the outer peripheral side of the toilet seat 3 from being discharged to the outside of the toilet apparatus 100.

[0146] The sealing portion 16 may not be provided on the outer peripheral edge of the toilet cover 4 (specifically, the lower end of the toilet cover side wall 41). In this case, the first cleaning nozzle 60a and the second cleaning nozzle 60b are preferably provided to open toward the inner peripheral side of the toilet seat 3.
