The top cover 6 is a cover that is opened and closed by the user. By covering the upper surface of the rear side of the base cover 4, the top cover 6 is positioned so as to cover the remote control storage section 51, the foam tank storage section 52, and the construction lid 8 fixed to the construction opening 7.

The construction opening 7 is provided on the upper surface of the base cover 4 and is an opening that communicates with the inside of the toilet body 2. The construction opening 7 is located rearward on the upper surface of the center side in the left-right direction of the base cover 4. The construction opening 7 is an opening provided for carrying out construction work inside the toilet body 2, such as connecting connectors and replacing parts. As shown in Figures 3 and 4, a construction lid 8 (lid) is fixed and positioned on the construction opening 7 so as to cover the construction opening 7.

In this embodiment, as shown in FIG. 3, the construction opening 7 is formed, for example, in a rectangular shape. The peripheral portion 71 (edge portion) of the construction opening 7 is formed at a position one step lower than the upper surface of the base cover 4. When the construction lid 8 is placed on the construction opening 7, the upper surface of the construction lid 8 becomes flush with the upper surface of the base cover 4. In this embodiment, the upper surface of the base cover 4 is inclined, and the construction lid 8 is placed on the inclined portion of the upper surface of the base cover 4. At the two rear corners of the construction opening 7, opening side screw fixing portions 72 that protrude inward are formed.

As shown in Figures 3 and 5, the opening side screw fixing part 72 has a protruding block 73 that protrudes inward from the corner of the construction opening 7, an insertion hole 731 formed in the protruding block 73, and an insert nut 74 placed in the insertion hole 731. The insertion hole 731 is formed by recessing downward from the upper surface of the protruding block 73 in a cylindrical shape.

As shown in FIG. 5, the insert nut 74 has a cylindrical portion 741 with a thread on the inner peripheral surface, and a flange portion 742 that protrudes radially outward from the upper end of the cylindrical portion 741. The insert nut 74 is inserted into the insertion hole 731. When the installation cover 8 is fixed with the screw 84, the insert nut 74 is inserted into the insertion hole 731 and the tip side of the shaft portion 842 of the screw 84 is inserted and screwed into the tip side of the shaft portion 842 of the screw 84.

As shown in Figures 3 to 5, the construction lid 8 has a lid body 81, an annular packing 86 (packing member, watertight structure), a screw 84, and a washer 85 (watertight structure). The lid body 81 is formed in a substantially rectangular plate shape. The lid body 81 is formed to a size that covers the peripheral portion 71, which is larger than the construction opening 7, so as to close the construction opening 7. The back surface of the lid body 81 is provided with an annular rib 811 that is positioned along the construction opening 7 and inside the construction opening 7 when the construction lid 8 is positioned to close the construction opening 7.

The lid body 81 has a pair of temporary fixing claws 82 (claws, temporary fixing parts) for temporary fixing, and a lid-side screw fixing through hole 83 (see FIG. 5) with a pair of screw fixing surfaces 831 (screw fixing parts, permanent fixing parts) for permanent fixing formed on the periphery. The lid body 81 is temporarily fixed to the peripheral part 71 of the construction opening 7 by the temporary fixing claws 82 on the front side, and is fixed to the peripheral part 71 of the construction opening 7 by the screws 84 on the rear side.

As shown in Figures 3 and 4, the pair of temporary fixing claws 82 are arranged spaced apart in the left-right direction on the front edge 81a side of the lid body 81. Each of the pair of temporary fixing claws 82 is composed of a claw that can be hooked onto the peripheral portion 71 of the construction opening 7. Each of the pair of temporary fixing claws 82 protrudes forward from the lower end of an annular rib 811 that protrudes downward from the back surface of the lid body 81 on the front edge 81a side of the lid body 81.

As shown in Figures 4 to 6, the temporary fixing claw 82 has a bent plate 821 and a reinforcing rib 822. The bent plate 821 has a base end extension plate 821a and an inclined extension plate 821b. The base end extension plate 821a extends a predetermined length forward from the lower end of the annular rib 811. The inclined extension plate 821b is bent at the front end of the base end extension plate 821a and extends forward at a downward incline from the front end of the base end extension plate 821a. The reinforcing rib 822 is formed to protrude downward from the lower surface of the bent plate 821 and extends in the front-to-rear direction.

A pair of lid-side screw fixing through holes 83 are formed on the rear side 81b of the lid body 81, opposite the front side 81a where the pair of temporary fixing claws 82 are arranged. When fixing the installation lid 8 to the installation opening 7, screws 84 are inserted through the lid-side screw fixing through holes 83.

A screw fixing surface 831 is formed on the periphery of the lid body 81 surface side of the lid side screw fixing through hole 83. The screw fixing surface 831 is composed of an annular surface formed at a position one step lower than the surface of the lid body 81. The screw fixing surface 831 can be screwed to the peripheral portion 71 of the construction opening 7 by a screw 84. When the shaft portion 842 of the screw 84 is inserted through the lid side screw fixing through hole 83, the head 841 of the screw 84 abuts against the screw fixing surface 831 and is fixed. When the shaft portion 842 of the screw 84 is inserted through the lid side screw fixing through hole 83, a washer 85 (watertight structure) is inserted into the shaft portion 842 of the screw 84.

When the installation lid 8 is fixed to the installation opening 53, the washer 85 is placed between the periphery of the back side of the lid side screw fixing through hole 83 of the lid body 81 and the upper surface of the protruding block 73 that protrudes inward from the corner of the installation opening 53. Therefore, the washer 85 prevents water from entering through the lid side screw fixing through hole 83. As a result, the washer 85 forms a watertight structure.

The annular packing 86 is formed in a ring shape along the periphery of the back surface of the lid body 81. The annular packing 86 is attached along the outer periphery of the back surface of the lid body 81, outside the annular rib 811 on the back surface of the lid body 81. When the construction lid 8 is placed so as to close the construction opening 7, the annular packing 86 is placed between the outer periphery of the lid body 81 and the periphery 71 (edge) of the construction opening 7. By sealing the outer periphery of the back surface of the lid body 81 and the periphery 71 of the construction opening 7 with the annular packing 86, the construction lid 8 has a watertight structure.

When the construction lid 8 configured as above is fixed to the construction opening 7, the construction lid 8 is temporarily fixed to the construction opening 7 by hooking a pair of temporary fixing claws 82 on the front side of the construction lid 8 to the peripheral portion 71 of the construction opening 7. After the temporary fixing, the shaft portion 842 of the screw 84 is inserted into the through hole 83 for fixing the screw on the lid side on the rear side of the construction lid 8, and the shaft portion 842 of the screw 84 is screwed into the insert nut 74 of the opening side screw fixing portion 72 of the construction opening 7, and the head portion 841 of the screw 84 is abutted against the screw fixing surface 831 of the construction lid 8 to fix the construction lid 8 to the construction opening 7.

The toilet device 1 of this embodiment described above provides the following effects. In the toilet device 1 of this embodiment, the toilet body 2 includes a base cover 4 and a top cover 6 arranged to cover at least a portion of the base cover 4. The base cover 4 has an installation opening 7 that communicates with the inside of the toilet body 2 and an installation lid 8 that is fixed and arranged to cover the installation opening 7, and the top cover 6 is arranged to cover the installation lid 8. As a result, the installation lid 8 is not exposed to the outside of the toilet device 1, improving the design.

In this embodiment, the construction opening 7 is provided at the rear of the top surface of the base cover 4. This makes it easier for workers to work inside the toilet body 2 from the rear of the top surface of the toilet device 1 through the construction opening 7.

In this embodiment, the installation lid 8 has a watertight structure. This prevents water from entering the interior of the toilet body 2.

In this embodiment, the watertight structure is formed by an annular packing 86 placed between the construction lid 8 and the peripheral portion 71 of the construction opening 7. This allows the annular packing 86 to seal between the construction lid 8 and the peripheral portion 71 of the construction opening 7, ensuring higher watertightness.

In this embodiment, the construction lid 8 is fixed to the construction opening 7 by a screw 84, and the watertight structure is formed by a washer 85 inserted into the screw 84. When the construction lid 8 is fixed to the construction opening 7 by the screw 84, it is fixed together with the washer 85 inserted into the screw 84, so that water can be prevented from entering the construction opening 7 through the lid-side screw fixing through hole 83 of the construction lid 8.

In this embodiment, the construction lid 8 is provided with a temporary fixing claw 82 for temporary fixing and a screw fixing surface 831 for final fixing. As a result, after temporary fixing with the temporary fixing claw 82, final fixing can be performed with a screw 84 on the screw fixing surface 831. Therefore, since the final fixing can be performed in a stable temporary fixed state, the work of attaching the construction lid 8 to the construction opening 7 can be easily performed.

In this embodiment, the temporary fixing claw 82 is configured as a claw that can be hooked onto the edge of the construction opening 7. This allows the construction lid 8 to be easily temporarily fixed by hooking the temporary fixing claw 82 onto the edge of the construction opening 7.

The above describes a preferred embodiment of the present disclosure. The present disclosure is not limited to the above-described embodiment, and can be modified as appropriate.

For example, in the above embodiment, the construction opening 7 is provided at the rear of the upper surface of the base cover 4. This is not limited to this, and for example, the construction opening 7 may be provided at the front of the upper surface of the base cover 54, or on the side or back.

In the above embodiment, the top cover 6, which is placed at the top, has been described as an example of the second cover. However, the present invention is not limited to this, and the second cover does not have to be the cover placed at the top. In other words, another cover may be placed on top of the second cover.
