Description

[Technical field]

[0001] The present disclosure relates to a toilet system. [Background technology]

[0002] Conventionally, there is known a toilet device in which an opening / closing body, which is at least one of a toilet seat and a toilet lid that are openably and closably mounted on a toilet body, is electrically opened and closed by a drive motor. The drive shaft of the drive motor is arranged coaxially with the rotation shaft of the opening / closing body (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-78375 A Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional toilet devices, it is necessary to secure space for installing a drive motor so that its drive shaft is coaxially arranged near the pivot shaft of the opening / closing body. Therefore, conventional toilet devices have a problem in that the layout of the pivot mechanism of the opening / closing body relative to the toilet body is restricted, and the freedom of design of the entire toilet device is low.

[0005] An object of the present disclosure is to provide a toilet apparatus that provides improved freedom in layout of a pivot mechanism for an opening / closing body relative to a toilet body. [Means for solving the problem]

[0006] The present disclosure relates to a toilet apparatus comprising an opening / closing body, which is at least one of a toilet seat and a toilet lid, which is openably and closably attached to a toilet body, and a rotation mechanism configured to be capable of interlocking with the rotation of the opening / closing body between a closed position and an open position, wherein the rotation mechanism includes an eccentric mechanism unit having an output shaft directly or indirectly connected to the opening / closing body, and at least one rotation assist device connected to the eccentric mechanism unit and assisting the rotation of the opening / closing body, and the output shaft is positioned in an eccentric position relative to the connection part of the rotation assist device with the eccentric drive part.

[0008] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. As shown in Figures 1 and 2, a toilet device 1 includes a toilet body 2, a toilet seat 3, a toilet lid 4, and a functional part 5. In the toilet device 1 shown in Figures 1 and 2, the toilet seat 3 is disposed in a closed position, and the toilet lid 4 is disposed in an open position.

[0009] In the coordinates X, Y, and Z shown in Figure 1, X is the front-to-back direction as seen by a user sitting on the toilet seat 3 of the toilet device 1. X1 is the front, and X2 is the back. Y is the direction intersecting the front-to-back direction, and is the width direction connecting the left and right sides of the user. Y1 is the right, and Y2 is the left. Z is the up-down direction along the vertical direction. Z1 is up, and Z2 is down. These coordinates X, Y, and Z are commonly used in all figures.

[0010] The toilet body 2 is a container having a toilet bowl 21 that is open at the top. The toilet bowl 21 is a recess formed in the toilet body 2. The toilet body 2 has a drain pipe 22 that extends from the lower part of the toilet bowl 21 toward the rear of the toilet body 2. The drain pipe 22 is located in the center of the width of the toilet body 2. The drain pipe 22 communicates with the inside of the toilet bowl 21, and is connected to a sewer pipe (not shown) at the rear of the toilet body 2.

[0011] A water supply pipe 23 is formed at the rear of the toilet body 2. The water supply pipe 23 is located at the center in the width direction of the toilet body 2 and above the drain pipe 22. The water supply pipe 23 extends forward from the rear of the toilet body 2. The front end of the water supply pipe 23 communicates with the interior of the toilet bowl 21 at the upper part of the toilet bowl 21. The rear end of the water supply pipe 23 is connected to a water supply facility (not shown), and a predetermined amount of flush water supplied from the water supply facility is supplied into the toilet bowl 21 along the rim 21a at the upper part of the toilet bowl 21. As a result, waste within the toilet bowl 21 is washed away and discharged through the drain pipe 22 into the sewer pipe.

[0012] The toilet seat 3 is disposed on the upper surface of the toilet bowl body 2, and is a member formed in a substantially annular shape with an opening in the center communicating with the opening of the toilet bowl 21. The upper surface of the toilet seat 3 on which the user sits is formed substantially flat. The toilet seat 3 has a pair of mounting arms 31, 31 that protrude backward. The pair of mounting arms 31, 31 are disposed on both the left and right sides of the toilet seat 3, and extend backward. The rear edge 32 of the toilet seat 3, disposed between the pair of mounting arms 31, 31, extends linearly in the width direction. The rear edge 32 may be formed to be smoothly curved across the mounting arms 31, 31. The pair of mounting arms 31, 31 of the toilet seat 3 are connected to a drive shaft 542 and a rotating shaft 543 (see FIG. 5) disposed in the functional unit 5 described later. As a result, the toilet seat 3 is attached to the toilet bowl body 2 so as to be able to rotate around the drive shaft 542 and the rotating shaft 543 to open and close. The toilet seat 3 is one of the opening and closing bodies 100 that the toilet apparatus 1 is equipped with.

[0013] The toilet lid 4 is placed on the upper surfaces of the toilet seat 3 and the functional part 5, and is a lid member formed in a shape that can cover the toilet seat 3, the opening of the toilet bowl 21, and the functional part 5 from above. The rear part of the toilet lid 4 is formed in a trapezoidal shape that gradually narrows towards the rear end. The rear part of the toilet lid 4 may be formed in a smoothly curved arc shape.

[0014] As shown in Figures 1 and 2, a pair of cushioning members 41, 41 made of an elastic material such as rubber are attached to the inner surface 4a of the front part of the toilet lid 4. The cushioning members 41, 41 are respectively disposed on both the left and right sides of the inner surface 4a of the toilet lid 4. When the toilet lid 4 is closed, the cushioning members 41, 41 come into contact with the upper surface of the toilet seat 3, thereby reducing the impact applied to the toilet seat 3 and toilet lid 4 and the generation of abnormal noise.

[0015] A pair of hinge portions 42, 42 are formed on the inner surface 4a side of the rear part of the toilet lid 4. The toilet lid 4 is connected at the hinge portions 42, 42 to an output shaft 613 (see FIG. 5) of a rotation mechanism 6 arranged in the functional unit 5. The output shaft 613 is the rotation shaft of the toilet lid 4. This enables the toilet lid 4 to be attached to the toilet body 2 so that it can rotate about the output shaft 613 to be opened and closed. The toilet lid 4 is another of the opening and closing bodies 100 equipped in the toilet apparatus 1.

[0016] The toilet lid 4 has an outer peripheral wall 43 that protrudes toward the inner surface 4a. The outer peripheral wall 43 is provided along the outer periphery of the toilet lid 4, except for the area where the hinge portions 42, 42 are provided. The outer peripheral wall 43 covers the outer periphery of the toilet seat 3 and functional portion 5 when the toilet lid 4 is closed. As a result, the toilet seat 3 and functional portion 5 are entirely contained within the inner space of the toilet lid 4. When viewing the exterior of the toilet apparatus 1 with the toilet lid 4 closed, the toilet seat 3 and functional portion 5 are not visible, so the toilet apparatus 1 has excellent design.

[0017] The functional section 5 is disposed inside the toilet body 2 on the rear side thereof, and houses various functional parts that fulfill the functions of the toilet device 1. The functional section 5 has a housing space extending above and to both the left and right sides of the water supply pipe 23, avoiding the water supply pipe 23 inside the toilet body 2. As shown in Figs. 1 to 3, the functional section 5 has a cover 51 that covers the upper part of the functional section 5. The cover 51 is removably provided on the toilet body 2. The cover 51 is disposed flush with the upper surface of the toilet seat 3. However, in order to visualize the inside of the functional section 5 for easy understanding, the cover 51 is omitted in Fig. 4. Furthermore, in Fig. 5, in addition to the cover 51, the toilet lid 4 is also omitted.

[0018] The cover 51 is disposed so as to cover the upper surface of the functional part 5 disposed between the pair of mounting arms 31, 31 of the toilet seat 3 and rearward of the rear end edge 32 of the toilet seat 3. The rear end side of the cover 51 is formed in the same shape as the rear part of the toilet lid 4. The cover 512 is integrally provided with a rear protruding part 511 that protrudes in a rectangular shape rearward from the center in the width direction. As shown in Figs. 1 to 3, the rear protruding part 511 is disposed between the pair of hinge parts 42, 42 of the toilet lid 4, and covers the output shaft 613 of the rotation mechanism 6 between the hinge parts 42, 42. As shown in Fig. 3, the rear end of the rear protruding part 511 is provided with a rear wall part 511a that is bent downward between the hinge parts 42, 42. The lower end of the rear wall part 511a is disposed so as to abut or be close to the rear upper surface 2a of the toilet body 2.

[0019] As shown in Figs. 3 to 5, the functional part 5 is provided with a local cleaning device 52. The local cleaning device 52 is disposed in the center in the width direction of the toilet body 2 and directly above the water supply pipe 23. The front end 52a of the local cleaning device 52 is disposed so as to face the inside of the toilet bowl 21, and the rear end 52b is disposed at the rear of the cover 51. As shown in Fig. 3, the local cleaning device 52 has a shape that is convexly curved upward from the front end 52a to the rear end 52b. The front end 52a is disposed lower than the rear end 52b. As a result, the local cleaning device 52 is disposed in the functional part 5 so as to be inclined downward from the inside of the functional part 5 toward the inside of the toilet bowl 21.

[0020] The private parts washing device 52 has therein a pair of private parts washing nozzles 521, 521 arranged in parallel on the left and right. The private parts washing nozzles 521, 521 are provided so as to be able to move forward and backward independently within the toilet bowl 21 by driving an advance / retract movement mechanism 522. Figs. 1 to 5 show a state in which only the left private parts washing nozzle 521 has moved forward and protruded into the toilet bowl 21. A wash water supply pipe (not shown) is connected to the rear end of the private parts washing nozzles 521, 521. The private parts washing nozzle 521 protruding into the toilet bowl 21 sprays wash water supplied from the wash water supply pipe from the nozzle portion 521a at the tip.

[0021] 4 and 5, in the functional section 5, a deodorizing device 53 is provided to the left of the private parts cleaning device 52. The deodorizing device 53 has an internal fan (not shown) that rotates when driven by a motor. The deodorizing device 53 communicates with the inside of the toilet bowl 21, and sucks in and deodorizes odors within the toilet bowl 21 by the rotation of the fan.

[0022] 4 and 5, in the functional part 5, an electric opening / closing device 54 for the toilet seat 3 is provided between the private parts cleansing device 52 and the mounting arm 31 on the right side of the toilet seat 3. The electric opening / closing device 54 is an opening / closing unit for electrically opening and closing the toilet seat 3, and has a drive motor (not shown) inside a case 541.

[0023] The electric opening / closing device 54 has a drive shaft 542 that protrudes from a case 541 in the width direction of the toilet body 2. The drive shaft 542 is a rotating shaft on the right side of the toilet seat 3, and is formed in a rectangular column shape. A rectangular column-shaped engagement hole 311 (see FIG. 4) that corresponds to the shape of the drive shaft 542 is formed in the mounting arm 31 on the right side of the toilet seat 3. The drive shaft 542 engages with the engagement hole 311 of the mounting arm 31.

[0024] As shown in Fig. 5, in the functional part 5, a rotation shaft 543 is provided on the left side of the toilet seat 3 between the deodorizing device 53 and the mounting arm 31 on the left side of the toilet seat 3. The rotation shaft 543 is formed in a cylindrical shape. The rotation shaft 543 is an axis that extends in the width direction of the toilet body 2, and is arranged coaxially with the drive shaft 542. The rotation shaft 543 is rotatably engaged with an axis hole (not shown) provided in the mounting arm 31 on the left side of the toilet seat 3.

[0025] When the drive motor of the electric opening / closing device 54 is driven, the driving force is transmitted to the right-side mounting arm 31 via the drive shaft 542. As a result, the toilet seat 3 rotates around the drive shaft 542 and the rotary shaft 543 to open and close. However, the toilet apparatus 1 also allows the user to manually open and close the toilet seat 3 around the drive shaft 542 and the rotary shaft 543 without operating the electric opening / closing device 54.

[0026] 2 and 3, the functional unit 5 is provided with a rotation mechanism 6 below the private parts cleansing device 52. The rotation mechanism 6 is a member that is connected to the toilet lid 4 and rotates the toilet lid 4 between an open position and a closed position.

[0027] The pivot mechanism 6 will be further described with reference to Figures 6 to 8. As shown in Figure 6, the pivot mechanism 6 is provided on the toilet body 2 and configured to be capable of interlocking with the pivoting of the toilet lid 4 between the closed position and the open position. The pivot mechanism 6 has an eccentric mechanism part 61 and an electric opening and closing device 62 for the toilet lid 4.

[0028] The eccentric mechanism 61 constitutes a main part of the rotation mechanism 6, and is located at the center of the functional part 5 in the width direction of the toilet body 2. The eccentric mechanism 61 includes a base plate 611 placed on the water supply pipe 23, a pair of support plates 612, 612 rising from the upper surface of the base plate 611, an output shaft 613 attached to the hinge parts 42, 42 of the toilet lid 4, and multiple rotation shafts. In one embodiment, the multiple rotation shafts are composed of three rotation shafts: a first rotation shaft 614, a second rotation shaft 615, and a third rotation shaft 616.

[0029] The surfaces of the pair of support plates 612, 612 face each other in the width direction of the toilet body 2, and are arranged parallel to the front-to-rear direction of the toilet body 2. The support plates 612, 612 are arranged parallel to each other with a fixed distance between them on the left and right. The lower ends of the support plates 612, 612 are attached to the base plate 611 with multiple screws 612a. The support plates 612, 612 extend upward from the base plate 611, gradually sloping toward the rear of the toilet body 2.

[0030] The output shaft 613 is a shaft located at the top of the eccentric mechanism part 61. The output shaft 613 extends in the width direction of the toilet body 2 across a pair of support plates 612. Both ends 613a of the output shaft 613 penetrate the support plates 612 and protrude outward on the left and right sides of the support plates 612, respectively. In this way, the output shaft 613 is rotatably supported between the support plates 612.

[0031] The output shaft 613 is a rotation shaft of the spur gear 613b. The spur gear 613b is provided on the outer periphery of the output shaft 613 that spans between the support plates 612, 612. As shown in Figures 6 and 8, both ends 613a, 613a of the output shaft 613 that protrude outward on the left and right sides of the support plates 612, 612 are provided with rectangular column-shaped connection ends 613c, 613c. The connection ends 613c, 613c are connected to the hinge parts 42, 42 by engaging with rectangular column-shaped grooves (not shown) formed in the hinge parts 42, 42 of the toilet lid 4. As a result, when the output shaft 613 rotates, the output shaft 613 can reliably transmit the rotational force to the toilet lid 4 without spinning freely relative to the hinge parts 42, 42.

[0032] Since the output shaft 613 is connected to a pair of hinge portions 42, 42 of the toilet lid 4 at both ends 613a, 613a, respectively, the torque load applied to the toilet lid 4 and the output shaft 613 can be reduced compared to when the output shaft 613 is connected to the toilet lid 4 by only one end. This allows the output shaft 613 to be made compact, and the installation space of the eccentric mechanism portion 61 in the functional portion 5 can be reduced. Since the torque generated when the output shaft 613 rotates is not applied only to one hinge portion 42 of the toilet lid 4, there is no risk of the toilet lid 4 being deformed. There is no need to precisely control the opening and closing operation of the toilet lid 4 to avoid deformation of the toilet lid 4.

[0033] The first rotating shaft 614 is disposed shifted downward and forward with respect to the output shaft 613. The first rotating shaft 614 is disposed parallel to the output shaft 613 across the pair of support plates 612, 612, and extends in the width direction. Both end portions 614a, 614a of the first rotating shaft 614 penetrate the support plates 612, 612, and protrude outward on the left and right sides of the support plates 612, 612, respectively. As a result, the first rotating shaft 614 is rotatably supported between the support plates 612, 612.

[0034] The first rotating shaft 614 is a rotating shaft of a spur gear 614b. The spur gear 614b is provided on the outer periphery of the first rotating shaft 614 extending between the support plates 612, 612. The spur gear 614b meshes with a spur gear 613b of the output shaft 613.

[0035] The second rotating shaft 615 is disposed offset downward and forward with respect to the first rotating shaft 614. The second rotating shaft 615 is disposed parallel to the first rotating shaft 614 across the pair of support plates 612, 612, and extends in the width direction. Both end portions 615a, 615a of the second rotating shaft 615 penetrate the support plates 612, 612, and protrude outward on the left and right sides of the support plates 612, 612, respectively. As a result, the second rotating shaft 615 is rotatably supported between the support plates 612, 612.

[0036] The second rotating shaft 615 is a rotating shaft of a spur gear 615b. The spur gear 615b is provided on the outer periphery of the second rotating shaft 615 extending between the support plates 612, 612. The spur gear 615b meshes with the spur gear 614b of the first rotating shaft 614.

[0037] The third rotating shaft 616 is disposed with a downward and forward shift with respect to the second rotating shaft 615. The third rotating shaft 616 is a shaft disposed at the lowest part of the eccentric mechanism 61. The third rotating shaft 616 is a shaft in the eccentric mechanism 61 that is the furthest from the output shaft 613. The third rotating shaft 616 is disposed parallel to the second rotating shaft 615 across the pair of support plates 612, 612, and extends in the width direction. Both ends 616a, 616a of the third rotating shaft 616 penetrate the support plates 612, 612 and protrude outward on the left and right sides of the support plates 612, 612, respectively. As a result, the third rotating shaft 616 is rotatably supported between the support plates 612, 612.

[0038] The third rotating shaft 616 is a rotating shaft of a spur gear 616b. The spur gear 616b is provided on the outer periphery of the third rotating shaft 616 extending between the support plates 612, 612. The spur gear 616b meshes with the spur gear 615b of the second rotating shaft 615.

[0039] 7, the output shaft 613, the first rotating shaft 614, the second rotating shaft 615 and the third rotating shaft 616 of the eccentric mechanism part 61 are arranged at an incline so as to be gradually shifted upward and backward from the third rotating shaft 616 towards the output shaft 613. This allows the eccentric mechanism part 61 to be arranged in a small space S below the local cleansing device 52 and above the water supply pipe 23 as shown in FIG.

[0040] Specifically, the vertical dimension of the space S is formed so that it is smaller on the front side and larger on the rear side. The space S is open upward and backward behind the local cleansing device 52. The eccentric mechanism 61 arranged in the space S is arranged between the local cleansing device 52 and the water supply pipe 23. The eccentric mechanism 61 extends backward and diagonally upward from the base plate 611 placed on the water supply pipe 23 so as to avoid interference with the local cleansing device 52 and the water supply pipe 23. The upper part of the eccentric mechanism 61 extends backward from between the local cleansing device 52 and the water supply pipe 23. The output shaft 613 is arranged at the same height as the rear end 52b of the local cleansing device 52 behind the local cleansing device 52. The output shaft 613 is arranged between the hinge parts 42, 42 of the toilet lid 4 and is connected to the hinge parts 42, 42 by the connection ends 613c, 613c.

[0041] As shown in FIG. 3, the eccentric mechanism part 61 disposed behind the private parts cleansing device 52 is covered from above to the rear by the rear protruding part 511 of the cover 51 having a rear wall part 511a between the hinge parts 42, 42 of the toilet lid 4.

[0042] The electric opening / closing device 62 is an opening / closing unit that electrically opens and closes the toilet lid 4, and is a rotation assisting device that assists in the rotation of the toilet lid 4 between the open and closed positions. The electric opening / closing device 62 has a drive motor and multiple gears (neither shown) for opening and closing the toilet lid 4 inside a case 621 that is long in the vertical direction. The electric opening / closing device 62 has a drive shaft 622 that protrudes from the right side of the upper part of the case 621. The drive shaft 622 is a shaft that rotates in conjunction with the drive of the drive motor via gears, and extends in the width direction of the toilet body 2.

[0043] In the rotation mechanism 6, the electric opening / closing device 62 and the eccentric mechanism 61 are separate components. The output shaft 613 of the eccentric mechanism 61 is provided separately from the electric opening / closing device 62. The output shaft 613 of the eccentric mechanism 61 is not disposed coaxially with the drive shaft 622 of the electric opening / closing device 62, but is disposed at an eccentric position relative to the drive shaft 622.

[0044] The drive shaft 622 of the electric opening / closing device 62 constitutes a connection part for the eccentric mechanism part 61. As shown in FIG. 6, the drive shaft 622 is coaxially connected to the left end part 616a of the third rotating shaft 616. As a result, the output shaft 613 is disposed in an eccentric position with respect to the drive shaft 622 of the electric opening / closing device 62. The electric opening / closing device 62 is disposed in a position shifted leftward from the eccentric mechanism part 61, and extends downward from the drive shaft 622. The electric opening / closing device 62 is disposed in a position shifted leftward from the local cleaning device 52 and the water supply pipe 23 without interfering with the local cleaning device 52 and the water supply pipe 23. The case 621 of the electric opening / closing device 62 is fixed to an appropriate part of the functional part 5 (not shown).

[0045] When the drive motor of the electric opening / closing device 62 is driven, the third rotating shaft 616 rotates via the drive shaft 622. When the third rotating shaft 616 rotates, a rotational force is transmitted to the second rotating shaft 615 via the spur gears 616b and 615b that mesh with each other. This causes the second rotating shaft 615 to rotate. When the second rotating shaft 615 rotates, a rotational force is transmitted to the first rotating shaft 614 via the spur gears 615b and 614b that mesh with each other. This causes the first rotating shaft 614 to rotate. When the first rotating shaft 614 rotates, a rotational force is transmitted to the output shaft 613 via the spur gears 614b and 613b that mesh with each other, and the output shaft 613 rotates. As a result, the toilet lid 4 connected to the output shaft 613 via the hinge parts 42 and 42 opens and closes. The electric opening / closing device 62 can apply a brake by the drive motor when closing the toilet lid 4 by driving the drive motor or manually. This allows the toilet lid 4 to be closed in a slow and quiet motion.

[0046] The first rotating shaft 614, the second rotating shaft 615, and the third rotating shaft 616 of the eccentric mechanism part 61 constitute a power transmission mechanism or a link mechanism that transmits the driving force of the electric opening-closing device 62 to the output shaft 613. Since the drive shaft 622 of the electric opening-closing device 62 does not need to be arranged coaxially with the axis of the hinge parts 42,42 of the toilet lid 4, even if sufficient installation space for the electric opening-closing device 62 cannot be secured on the toilet body 2 near the hinge parts 42,42, the driving force of the electric opening-closing device 62 can be transmitted to the hinge parts 42,42.

[0047] In the eccentric mechanism 61, the third rotating shaft 616 connected to the drive shaft 622 of the electric opening / closing device 62 is an input shaft to which the driving force of the electric opening / closing device 62 is input. The input shaft may be another rotating shaft provided in the electric opening / closing device 62, i.e., the first rotating shaft 614 or the second rotating shaft 615. Therefore, the drive shaft 622 of the electric opening / closing device 62 may be connected to either the end 614a of the first rotating shaft 614 or the end 615a of the second rotating shaft 615. In the eccentric mechanism 61, the input shaft to which the drive shaft 622 of the electric opening / closing device 62 is connected may be any rotating shaft among the multiple rotating shafts that does not interfere with other functional components arranged in the functional unit 5.

[0048] The number of rotating shafts provided in the eccentric mechanism part 61 can be appropriately increased or decreased depending on the size of the space S in which the eccentric mechanism part 61 is arranged. Therefore, the rotating shaft other than the output shaft 613 provided in the eccentric mechanism part 61 may be the first rotating shaft 614 only. The eccentric mechanism part 61 may be provided with four or more rotating shafts other than the output shaft 613.

[0049] Since the eccentric mechanism 61 has multiple rotating shafts, namely, a first rotating shaft 614, a second rotating shaft 615 and a third rotating shaft 616, any one or more functional components can be connected to any one of the ends 614a, 615a, 616a of these shafts.

[0050] 6, a free-standing unit 63 is connected to a third rotation shaft 616 of the eccentric mechanism 61. The free-standing unit 63 is fixed to a mounting plate 617 that rises upward from the right end of the substrate 611. The mounting plate 617 is attached to the substrate 611 by a screw 617a.

[0051] The self-supporting unit 63 is a known member, for example, a one-way clutch, and is a rotation assisting device that assists the rotation of the toilet lid 4 between the open position and the closed position. The self-supporting unit 63 does not generate torque in the direction to open the toilet lid 4, and does not rotate unless a certain torque or more is applied in the direction to close the toilet lid 4. The self-supporting unit 63 has a drive shaft 631 extending in the width direction. The drive shaft 631 of the self-supporting unit 63 constitutes a connection part for the eccentric mechanism part 61. The drive shaft 631 is connected to the right end part 616a of the third rotation shaft 616. As a result, the self-supporting unit 63 is positioned at a position shifted to the right of the eccentric mechanism part 61. The self-supporting unit 63 is positioned at a position shifted to the right of the local cleansing device 52 and the water supply pipe 23 without interfering with the local cleansing device 52 and the water supply pipe 23. That is, a drive shaft 622 of an electric opening / closing device 62 and a drive shaft 631 of a self-supporting unit 63 are connected to both ends 616a, 616a of a third rotation shaft 616 of an eccentric mechanism portion 61 shown in FIG.

[0052] The self-supporting unit 63 constantly generates a constant torque on the open toilet lid 4 via the eccentric mechanism 61, keeping the toilet lid 4 in the open position, even when the electric opening / closing device 62 is stopped. Therefore, the pivoting mechanism 6 having the self-supporting unit 63 can hold the open toilet lid 4 in a self-supporting position tilted forward from the angle of the center of gravity of the toilet lid 4, without using a separate biasing member such as an elastic body for keeping the toilet lid 4 in a self-supporting position.

[0053] Furthermore, as shown in FIG. 6, an assist spring 64 may be connected to the eccentric mechanism 61. The assist spring 64 is a known member formed of, for example, a coil spring, and is a rotation assist device that assists the rotation of the toilet lid 4 between the open position and the closed position. One end of the assist spring 64 is a connection part for the eccentric mechanism 61, and is fixed to the end 614a of the first rotating shaft 614. The other end of the assist spring 64 is fixed to the support plate 612 or another part of the functional part 5. As a result, the assist spring 64 is disposed in a position shifted to the right of the eccentric mechanism 61. The assist spring 64 is disposed in a position shifted to the right of the local cleansing device 52 and the water supply pipe 23 without interfering with the local cleansing device 52 and the water supply pipe 23.

[0054] The assist spring 64 applies a biasing force in the opening direction to the toilet lid 4 via the eccentric mechanism 61, and compensates for the torque required when rotating the toilet lid 4 in the opening direction by driving the electric opening / closing device 62 or manually. Therefore, the toilet lid 4 can be rotated to the open position with less power or force.

[0055] As shown in FIG. 9, the eccentric mechanism 61 may be provided with a slow-down unit 65 instead of the electric opening / closing device 62. The slow-down unit 65 is a known member, and is a rotation assisting device that assists the rotation of the toilet lid 4 between the open position and the closed position. The slow-down unit 65 is, for example, an oil damper. The slow-down unit 65 shown in FIG. 9 is connected to the third rotating shaft 616 of the eccentric mechanism 61 by a shaft 651 that is a connecting part to the eccentric mechanism 61. As a result, the slow-down unit 65 is disposed at a position shifted to the left of the eccentric mechanism 61. The slow-down unit 65 is disposed at a position shifted to the left of the pubic cleansing device 52 and the water supply pipe 23 without interfering with the pubic cleansing device 52 and the water supply pipe 23.

[0056] The slow-down unit 65 attenuates the torque acting in the closing direction on the toilet lid 4 when the toilet lid 4 is manually closed. Therefore, the toilet lid 4 can be closed slowly and quietly without applying a brake by the drive motor.

[0057] In the above description, the pivot mechanism 6 is configured to pivot the toilet lid 4, which is one of the opening / closing bodies 100, between the closed position and the open position, but the pivot mechanism 6 may also be configured to pivot the toilet seat 3, which is the other of the opening / closing bodies 100, between the closed position and the open position. In this case, the electric opening / closing device 54 for the toilet seat 3 is connected to the eccentric mechanism part 61 instead of the electric opening / closing device 62 for the toilet lid 4. This improves the degree of freedom in the layout of the electric opening / closing device 54. The pivot mechanism 6 may be provided corresponding to each of the toilet seat 3 and the toilet lid 4.

[0058] The output shaft 613 of the eccentric mechanism 61 is not limited to being directly connected to the opening / closing body 100. The output shaft 613 may be indirectly connected to the opening / closing body 100 via another appropriate power transmission mechanism.

[0059] The toilet device 1 of the present disclosure provides the following advantages.

[0060] (1) The toilet apparatus 1 of the present disclosure comprises an opening / closing body 100 which is at least one of a toilet seat 3 and a toilet lid 4 which are attached to a toilet body 2 in an openable and closable manner, and a rotation mechanism 6 which is provided on the toilet body 2 and configured to be capable of linking with the rotation of the opening / closing body 100 between a closed position and an open position, the rotation mechanism 6 including an eccentric mechanism part 61 having an output shaft 613 which is directly or indirectly connected to the opening / closing body 100, and at least one rotation assist device 62, 63, 64, 65 which is connected to the eccentric mechanism part 61 and assists in the rotation of the opening / closing body 100, the output shaft 613 being positioned eccentrically with respect to the connection part of the rotation assist device 62, 63, 64, 65 with the eccentric mechanism part 61.

[0061] According to the above (1), even if sufficient space cannot be secured near the opening / closing body 100 to place the rotation assist devices 62, 63, 64, 65, it is possible to transmit the driving force when the opening / closing body 100 is opened or closed between the opening / closing body 100 and the rotation assist devices 62, 63, 64, 65. Therefore, it is possible to provide a toilet apparatus 1 with improved freedom in layout of the rotation mechanism 6.

[0062] (2) In the toilet device 1 described in (1) above, the eccentric mechanism part 61 includes a plurality of rotating shafts 614, 615, 616 that are rotatably arranged in conjunction with the output shaft 613, and the rotation assist devices 62, 63, 64, 65 are connected to at least one of the plurality of rotating shafts 614, 615, 616.

[0063] According to the above (2), since the rotation assist devices 62, 63, 64, 65 can be connected to any of the multiple rotation shafts 614, 615, 616, the connection positions of the rotation assist devices 62, 63, 64, 65 away from the output shaft 613 can be adjusted according to the size of the installation space of the eccentric mechanism unit 61. Since any functional part can be added to any of the multiple rotation shafts 614, 615, 616, it is also possible to improve the functionality of the toilet device 1.

[0064] (3) In the toilet apparatus 1 described in (2) above, the output shaft 613 is disposed at the uppermost part of the eccentric mechanism part 61 .

[0065] According to the above (3), since the output shaft 613 is disposed in a position close to the opening-closing body 100, connection to the opening-closing body 100 is easy.

[0066] (4) In the toilet apparatus 1 described in (3) above, the output shaft 613 and the multiple rotating shafts 614, 615, 616 are arranged so that they are gradually shifted upward and backward from the rotating shaft 616 that is farthest from the output shaft 613 toward the output shaft 613.

[0067] According to the above (4), the opening / closing body 100 can be connected to the rear of the toilet body 2 while avoiding interference with functional parts provided on the toilet body 2.

[0068] (5) In the toilet apparatus 1 described in any one of (1) to (4) above, the eccentric mechanism part 61 is disposed at the rear part of the toilet body 2 and at the center part in the width direction.

[0069] According to the above (5), even when a rotation shaft is disposed at the rear part of the opening / closing body 100 which is formed with a narrow rear part, an output shaft can be connected to the opening / closing body 100.

[0070] (6) In the toilet apparatus 1 described in (5) above, the rotation assist devices 62, 63, 64, 65 are disposed at positions shifted to at least one of the right and left sides of the eccentric mechanism portion 61.

[0071] According to (6) above, the installation space for the eccentric mechanism unit 61 itself can be made compact, so that when installing the eccentric mechanism unit 61 in the toilet body 2, interference between the rotation assistance devices 62, 63, 64, 65 and the functional components within the toilet body 2 can be avoided.

[0072] (7) In the toilet apparatus 1 described in any one of (1) to (6) above, the output shaft 613 protrudes from the eccentric mechanism part 61 on both sides in the width direction, and both ends of the output shaft 613 are directly or indirectly connected to the opening / closing body 100.

[0073] According to the above (7), the torque load applied to the opening-closing body 100 and the output shaft 613 can be reduced compared to the case where the opening-closing body 100 is connected to the opening-closing body 100 by only one end of the output shaft 613. This allows the output shaft 613 to be made small, and the installation space for the rotation mechanism 6 can be reduced. Since the torque of the output shaft 613 is not applied to only one hinge portion of the opening-closing body 100, there is no risk of deformation of the opening-closing body 100. Therefore, there is no need to precisely control the opening and closing operation of the opening-closing body 100 in order to avoid deformation of the opening-closing body 100.

[0074] (8) The toilet apparatus 1 according to any one of (1) to (7) above, further comprising a private parts cleaning device 52, and the eccentric mechanism part 61 is disposed below the private parts cleaning device 52.

[0075] According to the above (8), the eccentric mechanism part 61 can be installed on the toilet body 2 without interfering with the private parts washing device 52.

[0076] (9) The toilet apparatus 1 described in (8) above further includes a water supply pipe 23, and the eccentric mechanism part 61 is disposed above the water supply pipe 23.

[0077] According to (9) above, the narrow space between the local cleaning device 52 and the water supply pipe 23 can be effectively utilized, and the eccentric mechanism unit 61 can be installed without interfering with the local cleaning device 52 and the water supply pipe 23.

[0078] (10) In the toilet apparatus 1 described in any one of (1) to (9) above, the eccentric mechanism portion 61 is provided with a plurality of rotation assist devices.

[0079] According to the above (10), the rotation mechanism 6 can assist the rotation of the opening / closing body 100 by various functions that the plurality of rotation assisting devices 62, 63, 64, and 65 respectively have. [Explanation of symbols]
