[0007] An embodiment of a toilet device 1 including a lifting mechanism 8 will be described below with reference to the drawings. In the following description, the front-to-rear direction is defined as the front-to-rear direction when viewed from a person sitting on the toilet seat 21 of the toilet device 1. The direction connecting the left and right that intersects with the front-to-rear direction is defined as the width direction. The vertical direction is defined as the up-down direction. In the drawings, F indicates the front of the toilet device 1, and R indicates the rear.

[0008] 1 and 2, the toilet device 1 of this embodiment includes a toilet seat 21, a toilet lid 22, a toilet body 10, a base 3, and a lifting mechanism 8. The toilet seat 21 and the toilet lid 22 are attached above the toilet body 10 so as to be rotatable relative to the toilet body 10.

[0009] The base part 3 is disposed at the upper part of the rear part of the toilet body 10. The base part 3 has functional parts, a front base part 31, a rear base part 32, a cover part 33, and electrical wiring 34 (see FIG. 6) that connects the functional parts. Examples of the functional parts include a hose, a flushing nozzle, a power supply unit, a control circuit board, an electric opening / closing unit that electrically opens and closes the toilet seat 21 and the toilet lid 22, a valve unit, various piping, etc. (all not shown). The functional parts are attached to the base part 3 taking into consideration their various functions and their positional relationships with other parts.

[0010] The cover portion 33 is a resin lid that covers the upper portions of the rear base portion 32 and the front base portion 31, which will be described below.

[0011] As shown in Figures 1 and 2, the rear base part 32 is disposed at the upper rear part of the toilet body 10. The rear base part 32 is formed from a resin material, and is formed so as to extend in the width direction and the front-rear direction of the toilet apparatus 1. Functional components are installed on the rear base part 32. The rear base part 32 is fixed to the toilet body 10 by inserting a pair of shaft members 321 extending from the underside of the rear base part 32 into mounting holes (not shown) in the toilet body 10.

[0012] 1 and 2, the front base part 31 is disposed above the rear part of the toilet body 10 and in front of the rear base part 32. The front base part 31 is formed so as to extend in the width direction and the front-rear direction of the toilet apparatus 1. The front base part 31 supports some of the functional components.

[0013] The front base part 31 is a part that is raised and lowered by the lifting mechanism 8 described below, and is configured to be movable in the vertical direction relative to the rear base part 32 and the toilet body 10. The front base part 31 is movable by the lifting mechanism 8 between a fixed position before being raised (see FIG. 1; first position) and a raised position after being raised (see FIG. 2; second position). The lifting mechanism 8 will be described later.

[0014] 3, the front base part 31 has a vertically elongated shape with its longitudinal direction aligned with the width direction of the toilet body 10. The front base part 31 is attached so that its width direction is aligned with the front-rear direction of the toilet body 10. The front base part 31 has a bottom surface part 311, an opening part 312, a guide rib part 313, a reinforcing rib part 314, and an electrical connection part 4.

[0015] As shown in Figures 3 and 5, the bottom surface portion 311 has a substantially flat surface that is installed on the upper surface 10a at the rear of the toilet body 10. A water stop gasket 315 is attached to the bottom surface portion 311 along the longitudinal direction of the front base portion 31. The water stop gasket 315 is a rubber member that is arranged so as to protrude downward from the bottom surface portion 311. The water stop gasket 315 is arranged so that it does not get wet from the toilet body 10 side when the front base portion 31 is attached to the toilet body 10.

[0016] 3 and 6, the opening 312 is formed in a substantially rectangular parallelepiped shape along the longitudinal direction of the front base portion 31 (the width direction of the toilet body 10) at one end side of the longitudinal direction of the front base portion 31 in the bottom surface portion 311. The opening 312 is a through hole that penetrates the front base portion 31 in the thickness direction. A bent portion 42 that is part of the electrical connection portion 4 described below is exposed from the opening 312.

[0017] As shown in FIG. 3, two guide rib portions 313 are formed along the width direction of the opening 312 having a substantially rectangular parallelepiped shape. The guide rib portions 313 protrude from the outer periphery of the opening 312 toward the inside of the opening 312. As shown in FIG. 6, the guide rib portions 313 are configured with L-shaped protruding pieces extending in a cantilever shape from one and the other ends of the opening 312 in the width direction to the opposing sides. The guide rib portions 313 protrude inward in the width direction on the lower side of the opening 312. The guide rib portions 313 each extend in the width direction of the opening 312 by substantially the same length, and are formed alternately as shown in FIG. 3.

[0018] The reinforcing rib portion 314 is formed in a substantially U-shape and has a pair of horizontal ribs 314a, 314b and a vertical rib 314c connecting the horizontal ribs 314a and 314b. The horizontal rib 314a is disposed between the two guide rib portions 313, and the horizontal rib 314b is disposed adjacent to one of the guide rib portions 313 and at a position spaced apart toward the inside in the width direction of the front base portion 31 in the opening 312. The pair of horizontal ribs 314a, 314b extend so as to connect one end of the opening 312 to the other end in the width direction. The vertical rib 314c connects the horizontal ribs 314a, 314b along the longitudinal direction of the opening 312. The reinforcing rib portion 314 is located above the guide rib portion 313 in the opening 312.

[0019] As shown in Fig. 6, the reinforcing rib portion 314 is formed above the opening 312 and has a plate-like shape extending downward from above the bottom surface portion 311. The reinforcing rib portion 314 has a pair of horizontal ribs 314a, 314b formed across the opening 312 in the width direction, and a vertical rib 314c connecting the horizontal ribs 314a, 314b to each other, thereby partially closing and narrowing the opening 312 and strengthening the rigidity around the portion where the opening 312 is formed. At the same time, by partially closing the opening 312 and extending downward from above, it is possible to prevent water from entering the front base portion 31 to some extent even if water splashes from below the opening 312 toward the inside of the front base portion 31.

[0020] As shown in FIG. 4, the electrical connection part 4 is a metal member connected to the upper surface of the bottom part 311 in the front base part 31. As shown in FIG. 4, the electrical connection part 4 is disposed on the outer edge side of the front base part 31, has a vertically long shape along the width direction of the front base part 31 (the front-rear direction of the toilet device 1) when viewed from above, and has a main body part 41 and a bent part 42. The main body part 41 is a vertically long part along the front-rear direction of the toilet device 1. The bent part 42 is a part whose front end side in the longitudinal direction is bent toward the inside of the front base part 31 along the width direction of the toilet device 1. As shown in FIG. 3, the bent part 42 of the electrical connection part 4 is the part exposed from the opening 312.

[0021] 5, the electrical connection part 4 is arranged such that the rear end side in the longitudinal direction of the main body 41 is located lower than the center and front end sides in a side view. The electrical connection part 4 is a thin, flat plate having a substantially constant thickness over its entire length. The electrical connection part 4 has a plurality of through holes 43 arranged at intervals to which terminals or the like can be connected, and the electrical wiring 34 can be connected via the terminals. The electrical connection part 4 is arranged above the bottom part 311 and the lowermost end surface of the bottom part 311 in the opening 312.

[0022] The electrical wiring 34 is a conductive line connected to each functional component of the toilet apparatus 1. The electrical wiring 34 can be grounded by connecting it to the electrical connection part 4 and extending an earth wire 340 that grounds the electrical wiring 34 from the electrical connection part 4. The electrical wiring 34 is connected to a desired through-hole in the electrical connection part 4 via a metal terminal.

[0023] As shown in Figures 1 and 2, the lifting mechanism 8 has an extendable lifting shaft 81, a lifting lever (not shown), an upper mounting plate 83, and a lower mounting plate 84, and is a mechanism for raising and lowering the front base portion 31, which is the subject of lifting and lowering, between a fixed position shown in Figure 1 and an elevated position higher than the fixed position shown in Figure 2.

[0024] The lower mounting plate 84 is a metal plate that is attached to the toilet body 10 and the rear base portion 32. The lower mounting plate 84 is a vertically elongated plate whose longitudinal direction is disposed along the width direction of the toilet body 10, and has through holes formed on one and the other of the longitudinal sides.

[0025] The telescopic lift shaft 81 is a shaft portion that is connected to the toilet body 10 and the underside of the front base portion 31 and can move up and down. Two telescopic lift shafts 81 are attached with a gap between them in the center of the width direction of the toilet device 1 on the front base portion 31. The telescopic lift shaft 81 passes through a through hole in the lower mounting plate 84 and is attached to the inside of the toilet body 10. The telescopic lift shaft can be extended and retracted up and down by the expansion and contraction force of a spring (not shown).

[0026] The upper mounting plate 83 is supported on the upper end of the telescopic lifting shaft 81 and is a metal plate having approximately the same width and length as the lower mounting plate 84. The upper mounting plate 83 is fixed to the lower surface of the front base part 31, so that the vertical movement of the telescopic lifting shaft 81 is linked to the front base part 31.

[0027] The lift lever is attached to protrude from the side of the toilet body 10. The lift lever is connected to the mounting upper plate and the telescopic lift shaft 81, and by operating the lift lever, it is possible to engage and release the spring, and the front base part 31 can be moved to a fixed position and a raised position.

[0028] As shown in FIG. 2, when the front base portion 31 is in the raised position, a space is formed between the upper surface 10a of the toilet body 10 and the lower surface of the bottom surface portion 311 of the front base portion 31. As shown in FIG. 6, the lower surface of the bottom surface portion 311 of the front base portion 31 is accessible from between the upper surface 10a of the toilet body 10 and the lower surface of the bottom surface portion 311 of the front base portion 31. Since the opening 312 is a through hole, a bent portion 42 of a part of the electrical connection portion 4 attached to the inside of the front base portion 31 is visible from the lower surface side of the bottom surface portion 311 and is exposed so that the electrical wiring 34 can be attached. Therefore, as shown in FIG. 6, an earth terminal is attached to the bent portion 42 of the electrical connection portion 4 exposed in the opening 312, and the earth wire 340 can be drawn from the inside of the front base portion 31 to the outside through the opening 312.

[0029] After being pulled out from the opening 312, the ground wire 340 is placed on the guide rib portion 313, rather than immediately hanging down. The ground wire 340 extending from the electrical connection portion 4 is guided from the opening 312 toward the outer end face of the front base portion 31. One end of the ground wire 340 is connected to the electrical connection portion 4, and the other end extends to the outside of the front base portion 31. This allows the functional components to be grounded.

[0030] 1, when the front base part 31 is lowered to a fixed position, the bottom part 311 of the front base part 31 is placed on the upper surface 10a of the toilet body 10. As a result, the opening 312 formed in the bottom part 311 is blocked by the upper surface 10a. Therefore, the bent part 42 of the electrical connection part 4 is also covered by the upper surface 10a of the toilet body 10 and cannot be seen from the outside.

[0031] The toilet device 1 of this embodiment provides the following effects. The toilet device is configured to include a base portion 3 that is disposed on the upper portion of the toilet body 10 and to which functional components are attached, a lifting mechanism 8 that raises and lowers a front base portion 31, which is at least a part of the base portion 3, between a fixed position and a raised position higher than the fixed position, and an electrical connection portion 4 that is disposed on the bottom surface portion 311 of the front base portion 31 in the base portion 3 and to which an electrical wiring is connected. Since the electrical connection portion 4 is disposed on the bottom surface portion 311 of the front base portion 31, when the base portion 3 is in the raised position, the electrical connection portion 4 is exposed so that the electrical wiring 34 can be attached. Therefore, when the base portion 3 is in the raised position, the earth wire 340 can be attached from the underside of the bottom surface portion 311 of the front base portion 31. When the front base portion 31 is in the lowered fixed position, the bottom surface portion 311 of the front base portion 31 is inaccessible, and therefore the earth wire 340 cannot be attached. Since the attachment point of the earth wire 340 is not visible when in a fixed position, it is possible to design a neat appearance. Since the electrical wiring to be grounded can be connected to the electrical connection part 4 and grounded from the bottom part 311, attachment of the earth wire 340, etc., is easy.

[0032] In this embodiment, at least a portion of the electrical connection part 4 is configured to be covered by the upper surface 10a of the toilet body 10 when the base part 3 is in a fixed position. When the front base part 31 is in the lowered fixed position, the bent part 42 of the electrical connection part 4 is covered by the upper surface 10a of the toilet body 10, making it difficult to visually confirm the mounting position, achieving the same effect as above.

[0033] In this embodiment, the base part 3 is configured to include an opening 312 formed in the bottom surface part 311, where a part of the electrical connection part 4 is exposed, and a guide rib part 313 that protrudes from the outer peripheral edge of the opening 312 toward the inside of the opening 312 and guides the earth wire 340 extending from the electrical connection part 4 from the opening 312 toward the outer end face of the base part 3. When the earth wire 340 is taken out from the opening 312 to the outside of the toilet body 10, the guide rib part 313 guides the earth wire 340 to the outer end face of the front base part 31. Therefore, the earth wire 340 does not hang down and interfere with the upper surface 10a of the toilet body 10 and bend. This makes installation easy and prevents the earth wire 340 from breaking.

[0034] In this embodiment, the opening 312 is formed penetrating the bottom surface portion 311 in the thickness direction, and the electrical connection portion 4 is disposed above the bottom surface portion 311 in the opening 312 relative to the lowest end surface of the bottom surface portion 311. Therefore, even if the top surface 10a of the toilet body 10 gets wet and water splashes on the bottom surface portion 311, the electrical connection portion 4 will not get wet. This makes it possible to prevent electricity from flowing in an unintended direction from the electrical connection portion 4 via water, and to prevent the electrical connection portion 4 from rusting.

[0035] In this embodiment, the base portion 3 is configured to include a reinforcing rib portion 314 that partially blocks the opening 312. Since the reinforcing rib portion 314 is formed in the opening 312, the strength of the periphery of the opening 312 can be ensured even if the volume of the opening 312 is large.

[0036] In this embodiment, the reinforcing rib portion 314 extends downward from above the bottom surface portion 311 at the opening 312. Since the reinforcing rib portion 314 extends downward from the upper portion of the bottom surface portion 311 at the opening 312, the reinforcing rib portion 314 can prevent water from entering the inside of the front base portion 31 when water is splashed obliquely from below to above.

[0037] In this embodiment, one end of the electrical wiring 34 is connected to the electrical connection portion 4, and the other end is extended to the outside of the base portion 3. This makes it easy to attach and ground the electrical wiring 34, and provides the same effects as those described above.

[0038] In this embodiment, the electric wiring 34 is configured with an earth wire 340 that grounds the electric wiring 34. By attaching the earth wire 340 to the electrical connection portion 4, it becomes possible to conceal the earth wire 340 when grounding, and the attachment becomes easy, and the same effect as above is achieved.

[0039] In this embodiment, the electrical connection part 4 is disposed on the outer edge side of the base part 3. By disposing the electrical connection part 4 on the outer edge side of the front base part 31, when performing electrical wiring work from around the toilet device 1, the installation position is close, making the work easier.

[0040] In this embodiment, the electrical connection portion 4 is exposed when the base portion 3 is in the raised position. When the base portion 3 is in the raised position, the ground wire 340 can be attached from the lower surface of the bottom portion 311 of the front base portion 31, thereby achieving the same effect as above.

[0041] The present disclosure is not limited to the above-described embodiment, and modifications, improvements, etc. are included in the present disclosure. For example, the electrical wiring 34 may be electrical wiring for another device to be installed in the toilet device 1 later. When adding a pressure pump or a separate buttocks washing device or heating device during renovation, electrical wiring can be connected via the electrical connection part. The lifting mechanism may lift and lower the entire base part. The electrical connection part may be disposed in the rear base part. [Explanation of symbols]
