It is common practice to pivot the toilet seat to this casing. A sanitary washing device for washing the buttocks of a human body with warm water using hot water spouted from a washing nozzle provided in the casing is also widely used. In some cases, a warm air fan is installed in the casing, and after washing, warm air is blown to the human buttocks to dry the buttocks with hot air. In some cases, a deodorizing device is installed in the casing to deodorize the odor in the toilet bowl.

By the way, sewage such as urine enters into a gap between the casing and the upper surface of the Western-style toilet and sticks,
May cause odor. Therefore, a sanitary washing device in which the front edge of the casing is detachable is disclosed in Japanese Patent Laid-Open No. 5-3 / 1993.
No. 46033.

FIG. 9 shows the configuration of the sanitary washing device of the same publication, and the main body (casing) 2 of the sanitary washing device is shown in FIG.
1 includes a first main body 21a mounted on the rear upper surface of the toilet and a detachable second main body 21b on the front side. Second body 2
The side surface 37a of 1b is provided with a convex portion 38 having elasticity. The inner surface 3 of the first main body 21a facing the convex portion 38
0a has a notch 39, and one end is in contact with the convex 38,
The other end is exposed on the outer side surface 30b of the first main body 21a and includes a slidably provided release button 41a. The second main body 21b includes a boss 42. A hole 43 is formed in the wall surface of the first main body 21a facing the boss 42.
Is provided. By pressing the sliding shaft 41 from the outer surface 30b, the step 38b of the convex portion 38 of the second main body 21b is formed.
Is forcibly disengaged, and the second main body 21b is
1a. By separating the second main body 21b, it is possible to sufficiently clean the upper surface of the Western-style toilet below the second main body 21b.

[0005]

The above-mentioned JP-A-5-34
In the sanitary washing device of No. 6033, when a large force is applied to the front edge, the second main body 21b may be detached.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a toilet seat device which can surely prevent generation of odor due to sticking of sewage and is excellent in durability.

[0007]

SUMMARY OF THE INVENTION A toilet seat device according to the present invention is a sanitary device having a casing installed on the rear upper surface of a Western-style toilet bowl and having a front opening for opening a nozzle, and a toilet seat supported by the casing. In the cleaning device, a plate at the bottom on the front edge side of the casing is detachable or movable backward.

According to such a toilet seat device, a gap is provided between the front edge side of the casing and the upper surface of the Western-style toilet by removing the bottom plate or retracting the same rearward to clean and remove dirt attached to the upper surface of the Western-style toilet. can do.

When the bottom plate is detachable, the plate can be removed and washed.

[0010]

1 and 2 are overall perspective views of a Western-style toilet provided with a toilet seat device according to an embodiment. FIG. 3 is a sectional view taken along the line III-III in FIG.

A low tank (not shown) is installed on the rear upper surface of the Western style toilet 1, and a tank cover 2 is installed so as to cover the low tank. The front of the tank cover 2 protrudes forward from the rear edge of the toilet bowl 3 of the Western-style toilet bowl 1,
An opening 4 is provided in the lower surface portion.

A cleaning nozzle 5 is provided in the tank cover 2. The cleaning nozzle 5 includes a nozzle body 5a that can protrude into the toilet bowl 3.

By projecting the nozzle body 5a and jetting hot water from its tip, the buttocks of the user sitting on the toilet seat 6 can be washed with hot water. The toilet seat 6 is rotatably attached to the tank cover 2 together with the toilet lid 7.

There is a gap S between the front edge side of the tank cover 2 and the upper surface of the Western-style toilet 1, and the bottom plate 8 is inserted into the gap S. The bottom plate 8 is detachably attached to the tank cover 2 by, for example, a magnet.

In FIGS. 2 and 3, the bottom plate 8 is inserted to the depth of the gap S, and the Western style toilet 1 is in a usable state.

When cleaning the upper surface of the Western style toilet 1 facing the gap S, the bottom plate 8 is pulled out as shown in FIG.
At this time, if necessary, the bottom plate 8 is washed with a detergent or the like.

In this manner, dirt that has entered the gap between the bottom surface of the front edge of the tank cover 2 and the Western-style toilet 1 can be sufficiently cleaned and removed, and odor can be sufficiently prevented.

In this embodiment, the front edge of the bottom of the tank cover 2 is fixed to the fixed base plate 9.
And the bottom plate 8, and the washing nozzle 5 is fixed to the fixed base plate 9 via the bracket 10.
It is fixed to.

FIGS. 4 to 8 show a Western-style toilet provided with a toilet seat device according to another embodiment of the present invention.

In this embodiment, a bottom plate 11 is mounted on the bottom surface of the tank cover 2A below the fixed base plate 9A so as to be slidable in the front-rear direction along the upper surface of the Western-style toilet bowl 1. As shown in FIGS. 7 and 8, the bottom plate 11 is provided with an elongated hole 12 extending in the front-rear direction of the Western-style toilet bowl 1, and the fixed base plate 9
A guide block 13 protruding from A engages with the elongated hole 12.

On the upper surface of the bottom plate 11, a rack 14 extending in the longitudinal direction of the Western-style toilet bowl 1 is provided, and a pinion 15 is engaged with the rack 14. The pinion 15 is fixed to a rotating shaft of a motor 16. The motor 16 is installed on the fixed base plate 9A,
The pinion 15 meshes with the rack 14 through the opening 17 of the fixed base plate 9A.

By operating the motor 16, the bottom plate 11 can be moved forward and backward. In FIG. 4, the bottom plate 11 is located at the limit of forward movement, and the Western-style toilet 1 is in use. By retreating the bottom plate 11 as shown in FIG. 5, a gap S is left between the front edge side of the tank cover 2A and the upper surface of the Western style toilet 1, and the upper surface of the Western style toilet 1 can be sufficiently cleaned. Thereby, generation of odor can be surely prevented.

In the above embodiment, the tank covers 2, 2A
Although this also serves as the casing of the toilet seat device, the present invention can be applied to a toilet seat device using a toilet seat box as a casing.

In the above embodiment, the sanitary washing device is provided, but a hot air drying device or a deodorizing device may be provided.

[0025]

As described above, according to the present invention, it is possible to prevent sewage from entering between the casing and the upper surface of the Western-style toilet bowl and generating odor.
