It takes time to apply and dry the adhesive, making efficient production impossible. In addition, when the toilet seat body and the toilet seat bottom plate are joined by vibration welding, a special device such as a vibration welding device is required, and the strength of the toilet seat unit may be insufficient due to poor adhesion due to work variation. In addition, if a part inside the toilet seat unit breaks down, the toilet seat body and the toilet seat bottom plate cannot be disassembled by bonding with an adhesive or vibration welding or the like, so that the entire toilet seat unit needs to be replaced. Further, when the product is discarded, the toilet seat body and the toilet seat bottom plate cannot be easily disassembled, so that it is difficult to separate the resin material from the electrical components inside the toilet seat. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a toilet seat that can be easily assembled and easily disassembled.

The toilet seat body and the bottom plate are joined and assembled using a third member, so that a solvent such as an adhesive is used for joining the toilet seat body and the bottom plate. And time for drying the adhesive or the like can be saved. In addition, since there is no need for adhesive application or vibration welding, a special device for adhesive application work and vibration welding is not required. Therefore, the assembling can be simplified, the assembling time is shortened, and the assembling property is excellent. Also, since it is not bonded with an adhesive or vibration welding, it can be disassembled and reassembled, and even if a failure such as a heater disconnection occurs, the bottom plate can be removed from the toilet seat body, making repairs extremely easy. .

It is formed so as to be stretched up to.

(Explanation of Relationship between Toilet Lid 10, Toilet Seat 20, and Apparatus Main Body 30) Since the toilet lid 10, the toilet seat 20, and the apparatus main body 30 are formed as described above, the toilet lid 10, the toilet seat 20 Since the curved surface 31f of the apparatus main body 30 and the curved surface 10e of the toilet lid 10 form a continuous surface in a concentric arc shape, a clean impression is given. This clean impression has succeeded in further strengthening the impression because the side surfaces of the toilet lid 10 and the toilet seat 20 are formed on the same plane as the side surface of the apparatus main body 30. Also, the hinge portion 20c
The concentric shape does not change the neat impression even when the toilet lid 10 is opened. Further, the left and right sides of the toilet seat / toilet lid support portion 31b are defined as inclined concave portions 31c,
Since this is a rotation space for the toilet lid 10 and the hinge portions 10b and 20c of the toilet seat 20, the central rear end portion 20i of the toilet seat 20 can be used as a seat surface. In addition, the inside of the toilet seat / toilet lid support portion 31b is effectively used as a storage space,
The apparatus main body 30 can be made compact. Furthermore, the maximum height position of the apparatus main body 30 is lower than the maximum height position of the toilet lid 10 when the toilet lid 10 is in the down state, that is, the upper surface of the flat surface 31p of the apparatus main body 30 is Is lower than the position of the hinge portion, the entire local cleaning device is made compact and the portability of the device is improved. The device body 30 has a bulging portion between the hinge portions 10c, 20c of the toilet seat 20 and the toilet lid 10, which is substantially the same height as the maximum height of the hinge portions 10c, 20c and contains a functional component therein. Although formed, the maximum height position of the apparatus main body 30 mentioned here does not include this bulging portion. This bulging part is just right and left hinge part 10c,
20c, the hinge portions 10c, 20c
There is a sense of unity. Therefore, since there is no member that rises higher than the rear part of the toilet lid 10 or the toilet seat 20, the compactness of the local cleaning device has been made more conspicuous. It is the center of the concentric arc and the toilet lid 1
0, the center of rotation of the toilet seat 20 is substantially the same height as the flat surface 31p. By doing so, the rotation trajectories of the hinge portions 10b and 20c of the toilet lid 10 and the toilet seat 20 are not drawn behind the flat surface 31p, and there is no need to take an extra inclined concave portion 31c. The gap with the apparatus main body 30 can be narrowed. Furthermore, the height and the curved surface R of the bulged portion of the apparatus main body 30 and the portion of the toilet lid 10 located on the outer side in the axial direction are substantially equal.
In a state in which the toilet lid 10 is closed, the gap between the end of the toilet lid 10 and the device main body 30, the gap between the end of the toilet seat 20 and the device main body 30, and the gap between the toilet seat 20 and the toilet lid 10 are The gaps were set as small gaps having approximately uniform dimensions of about 2 mm. The minute gap is maintained at a similar size even when the toilet seat and the toilet lid are opened. Therefore, it was possible to have a substantially full-flat surface with few irregularities on the surface, eliminating a dent between the apparatus main body and the toilet lid, which the conventional local cleaning device had, and having no gap. Therefore, the design of the product is remarkably improved, and even if dirt adheres to the gap, it is inconspicuous.
