The cover 3b is provided with a human body detection sensor for detecting a human body approaching or sitting on the toilet body 1.

  A rear base plate 4a is provided on the upper surface of the rearmost part of the toilet body 1 so that the rear side of the cover 3b is covered from above. The rear base plate 4a is provided with a heater-equipped warm water tank 4b (shown only in FIG. 5) for supplying warm water to the warm water washing nozzle, and for guiding the movement when the toilet seat box 2 is pushed up or lowered. A guide 11 for the levitation unit 10 is installed. The rear base plate 4a is provided with a room heating fan (not shown) including a heater and an electric fan, a power supply board, a control circuit board, a valve unit for supplying water to a toilet bowl and a trap part, and the like.

  The levitation unit 10 includes a slider 12 fixed to the rear edge of the front base plate 3a, the guide 11 that guides the raising and lowering of the slider 12, and a constant load spring that constantly applies a constant upward biasing force to the slider 12. Device 20.

  The guide 11 is fixed to the front portion of the rear base plate 4a via a mounting piece 11a protruding rearward. A front extending piece 11b extends from the guide 11 and is configured to resist a load applied to the guide 11 in the forward direction.

  As shown in detail in FIG. 2, the constant load spring device 20 includes a frame 21 fixed to the upper end surface of the guide 11, and a drum body 23 rotatably supported on the frame 21 via a support shaft 22. And a bracket 24 erected from the upper end surface of the slider 12, and a constant load spring 27 made of a leaf spring wound around the drum body 23 and connected to the bracket 24 via a fastening member 25 at the front end side. . The base end side of the constant load spring 27 is wound around the drum body 23 over a predetermined length, and the base end of the constant load spring 27 is fixed to the drum body 23. The constant load spring 27 is shaped like a spiral wound around the drum body 23. When the constant load spring 27 is pulled out from the drum body 23, the constant load spring 27 warps in a spiral shape and tries to wind around the drum body 23. A constant upward bias is applied from the load spring 27. FIG. 3 schematically shows the characteristics of the constant load spring. As shown in the drawing, the upward biasing force is constant in the up-and-down region of the slider 12.

  The support shaft 22 is integrated with the drum body 23. One end of the support shaft 22 is connected to a rotary damper 28 for slowing the descending speed of the slider 12. The rotary damper 28 is fixed to the frame 21. The rotary damper 28 rotates in the forward direction when the slider 12 moves up and rotates in the reverse direction when the slider 12 moves down. At the time of this forward rotation, the rotary damper gives no or little braking, but at the time of reverse rotation, a predetermined braking is applied to the rotation, and the slider 12 descends slowly.

  The guide 11 is provided with a latch piece 31 that lightly latches the raised front base plate 3a and a latch unit 30 having a latch spring (not shown), and the front base plate 3a is lowered even if the hand is released from the case 3b. It is configured not to do. The latch piece 31 is biased by a latch spring so as to protrude into the advance / retreat area of the slider 12. The slider 12 is provided with a recess 32 with which the latch piece 31 is engaged.

  In this embodiment, the rear base plate 4a is a fixed member, and the front base plate 3a and the cover 3b are elevating members.

In the toilet stool having a configured toilet top facilities Thus, the hitting a floating the toilet seat box 2, by pulling over the hand to the case 3b, as in FIG. 5 (b), the front base plate 3a and The cover 3b rises. In addition, the toilet seat illumination 3g is turned on. Thereby, the lower space (lower area) S of the front part of the toilet seat box 2 that has surfaced is illuminated. Since the lower region S is thus brightly illuminated, the upper surface of the toilet body 1 facing the lower region S, the lower surface of the front base plate 3a, and the like can be easily cleaned. When the front base plate 3a and the cover 3b are raised to a predetermined height, the latch piece 31 engages with the recess 32.

  At this time, the slider 12 rises along the guide 11. A predetermined upward biasing force is applied to the slider 12 from the constant load spring 27. For this reason, the cover 3b and the front base plate 3a are smoothly raised only by applying a lifting force slightly upward. Moreover, since the lifting force is constant even if the height of the slider 12 changes, the toilet seat box 2 can always be raised easily from the beginning of the lifting until the end of the lifting. As described above, the rotary damper 28 does not apply braking when the slider 12 is raised.

  In order to lower the cover 3b and the front base plate 3a, the cover 3b is pushed downward with a slight force. Thereby, the engagement between the latch piece 31 and the recess 32 of the latch unit 30 is released, and the cover 3b and the front base plate 3a are lowered as shown in FIG.

  During this lowering, the slider 11 moves down along the guide 12. In this case, since the constant load spring 27 is unwound from the drum body 23 and the rotary damper 28 is reversed, braking is applied to the rotation of the drum body 23. For this reason, the cover 3b and the front base plate 3a descend slowly.

  At the time of this lowering, the upward biasing force of the constant load spring 27 is always constant, so that it can be lowered smoothly until reaching the bottom.

  In the above-described embodiment, the slider 12 is urged to be pulled up by the constant load spring 27, but a constant load spring may be provided to push up the slider 12.

  In the above embodiment, the toilet upper surface facility is a toilet seat box, but may be a tank cover. The shape and size of the toilet seat box and tank cover are not particularly limited. The toilet seat box and the tank cover may be moved up and down only at the front part, and may be moved up and down including the rear part from the front part.

  In the above embodiment, the descending speed is slowed by the rotary damper, but a slowing device such as another damper mechanism may be adopted.
