A main body 90 having a cleaning function unit 13 composed of 1,132 is provided.

As shown in FIGS. 10 and 11, the installation plate 94 is a U-shaped plate having vertically extending vertical surface portions 940 on both sides, and a mounting bolt 45 (see FIG. It is fixed on the toilet bowl 5 by 10). Further, as shown in FIG. 10, the main body 90 has a warm water tank 98 for storing water for cleaning therein and the like, and has a toilet seat 11 and a toilet lid 12 rotatably. Further, on both sides of the main body 90, there are sleeve portions 92 slidably attached to the vertical surface portion 940 of the installation plate 94.

The sleeve portion 92 of the main body 90 has two protrusions 921 as shown in FIG.
A lock protrusion 923 that can be moved in and out is provided between 21. As shown in FIG. 12, the lock convex portion 923 has a sleeve portion 92.
The lever 924 provided outside is retracted by rotating it in the direction of arrow E, and the lever 924 is released so that it is projected to the original position by a spring (not shown).

On the other hand, the vertical surface portion 940 of the installation plate 94
As shown in FIG. 11, two guide grooves 941 extending in the vertical direction are provided at positions corresponding to the protrusions 921 of the main body 90. The upper portion of the guide groove 941 is bent in an inverted U shape, and a holding portion 942 is provided downward at the tip thereof.

Further, between the two guide grooves 941, two lock holes 945 and 946 which can be engaged with the lock protrusion 923 of the main body 90 are provided in the upper and lower directions. The upper lock hole 945 is provided so as to engage with the lock protrusion 923 when the protrusion 921 of the main body 90 is located in the holding portion 942 of the guide groove 941, while the lower lock hole 945 is provided. 946 is provided to engage with the lock protrusion 923 when the protrusion 921 of the main body 90 is located at the lower end 943 of the guide groove 941.

Therefore, the work of pulling up the main body 90 must be performed with great care.

As described above, the main body 90 is equipped with the hot water tank 98, the toilet lid 12, the toilet seat 11, etc., and is usually about 5 k.
It exceeds g and is relatively heavy to pull it up manually. Therefore, when vertically moving while supporting the entire load of the main body 90 by human power, there is a possibility that the main body 90 may be dropped during the process. Therefore, there are also safety issues.

The present invention has been made in view of the above-mentioned conventional problems, and a floating mechanism of the main body for moving the main body safely and easily for forming a gap for cleaning. It is intended to provide a flush toilet seat having

[0012]

According to a first aspect of the present invention, there is provided a main body having a cleaning function and a toilet bowl. The main body is a flush toilet seat having a toilet seat and a toilet lid rotatably, wherein the flush toilet seat is A washing toilet seat with a levitation mechanism having a levitation mechanism for levitation of the main body so as to form a cleanable gap between the toilet bowl and the main body.

What is most noticeable in the present invention is that the main body has the levitation mechanism between the main body and the toilet bowl. For the levitation mechanism, it is possible to use a means for elastically assisting the levitation of the main body by human power, such as a damper means described later, or a means that uses an actuator such as an air cylinder and does not use human power at all.

The levitation mechanism may be provided directly between the main body and the toilet bowl, or may be provided between the main body and the installation plate. Here, the floating of the main body means moving the main body so as to provide the cleanable gap portion between the rear surface of the main body and the upper surface portion of the toilet bowl facing the main body. The main body can be moved by a method of sliding it upward, a method of rotating it outward of the toilet bowl, or the like, as will be described later.

Next, the operation of the present invention will be described. The flush toilet seat of the present invention has the floating mechanism. Therefore, when it is desired to clean the space between the main body and the toilet, the main body can be easily floated by using the levitation mechanism.
The void portion for cleaning can be formed safely and easily.

That is, the floating operation of the main body can be performed while supporting the load of the main body by the floating mechanism, and it is not necessary to perform the total load of the main body while manually supporting the load. Therefore, it is possible to reliably prevent troubles such as breaking the balance or dropping the balance while the main body is moving. Therefore, as described above, the cleaning void portion can be formed safely and easily.

Next, as in the invention of claim 2, the levitation mechanism has a rotating mechanism for rotating the main body in the outward direction of the toilet, and the rotating mechanism has the above-mentioned structure. It is preferable to have a rotation shaft that connects between the installation plate fixed to the toilet and having the main body and the main body, and a damper means for elastically rotating the main body.

The damper means uses elastic bodies such as springs, compressive force of gas, liquid and the like, movement resistance, etc. to elastically absorb fast movements and elastically absorb and absorb strong impacts. It is what makes me. In the present invention, the damper means is used to elastically rotate the main body as described above.

Therefore, in the present invention, by using the rotating mechanism having the damper means, the work of floating the main body can be performed more easily and safely.

Next, according to a third aspect of the present invention, the rotation shaft of the main body is provided on the side portion of the installation plate so that the main body can be rotated toward the side portion of the toilet bowl, and The damper means is preferably interposed between the main body and the toilet bowl or the installation plate. As a result, the main body can be largely rotated in the direction of one side of the toilet bowl, and a very large cleaning gap can be formed with the other side of the toilet completely open. Therefore, the convenience at the time of cleaning can be further improved.

According to a fourth aspect of the present invention, the rotation shaft of the main body is provided on the upper surface of the installation plate so that the main body can be rotated in the rearward direction of the toilet, and the damper is provided. The means may be interposed between the main body and the toilet bowl or the installation plate. In this case, since the rotation direction of the main body is the rear direction, the back surface of the main body can be opened in the front direction and the cleaning operation can be facilitated.

Next, as in the invention of claim 5, the levitation mechanism has an elevating mechanism for elevating and lowering the main body with respect to the toilet bowl, and the elevating and lowering mechanism elevates and lowers the main body. It is also possible to adopt a structure having a damper means for elastically performing the operation and a lock portion for holding the main body in the raised position. In this case, unlike the case where the rotating mechanism is used, the gap can be provided by sliding the main body in the vertical direction, and the moving space of the main body can be reduced.
