DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which a cover box is installed on a rear upper surface of a Western-style toilet bowl.

[0002]

2. Description of the Related Art When a low tank is installed on the rear upper surface of a Western style toilet or the like, a low tank made of synthetic resin or the like may be covered with a low tank cover as shown in FIGS. In addition,
FIG. 3 is a perspective view of a Western-style toilet provided with a cover box installation structure according to a conventional example, and FIG. 4 is an internal perspective view of the same.

[0003] A low tank 2 is installed on the rear upper surface of the Western-style toilet 1, and the low tank 2 is covered with a low tank cover 3. In this conventional example, the low tank cover 3 includes a cover middle 5 provided on a base plate 4 and a cover top 7 having a hand basin 6 provided above the cover middle 5.

In the low tank 2, a float valve device 8, a ball tap 9, and effluent (clear water) from the ball tap 9.
A fresh water tank 10 and the like for receiving and supplying the hot water to the hot water washing device are provided. A water supply pipe 11 is connected to the ball tap 9. Further, a hose 12 branched from the ball tap 9 is connected to the hand-washing spout tube 13.

[0005] The float valve device 8 includes a low tank cover 3.
Is operated by a handle 14 provided on the tank middle 5 of the first embodiment.

[0006] Inside the low tank cover 3, the washing nozzle 1 is provided.
A hot water washing device provided with a hot air blower 5 and a hot air blower 17, a hot air drying device for blowing hot air from a hot air outlet 17, a deodorizing device including an adsorber 20 for removing odor in the toilet bowl 19 and a fan 21 are provided. .

[0007] The toilet seat 23 incorporates a heater for heating. 24 is a toilet lid. This hot water washing device,
To control the hot air drying device, deodorizing device and heater,
A remote controller 25 is installed on the wall of the toilet room.

A low tank 2 is provided on the rear upper surface of the Western style toilet 1.
When installing various electrical components, as shown in FIG. 5, the low tank 2 and the various electrical components are assembled on the base plate 4, covered with the low tank cover 3 and integrated to form a cover box 30, and the integrated cover box is provided. 30 is installed on the rear upper surface of the Western style toilet 1.

The base plate 4 is provided with four bolts 31 projecting downward, of which two bolts 31 on the front side are provided.
(31f) is slidable in the front-rear direction. The Western-style toilet 1 is provided with four bolt holes 32. The cover box 30 is slowly lowered onto the rear upper surface of the Western-style toilet 1 while holding the cover box 30 so that the bolts 31 are inserted into the bolt holes 32. Next, washer 3
3. Tighten the nut 35 to the bolt 31 via the spring washer 34 to fix the cover box 30.

FIG. 6 shows a nut 3f attached to the bolt 31f on the aforementioned side.
It is sectional drawing which shows the state which tightened 5. The base plate 4 is provided with a groove 36 extending in the front-rear direction of the Western-style toilet bowl, and the square bolt head 37 of the bolt 31f is attached to the groove 3
6 is slidably inserted. The reason why the bolt 31f can be slid in the front and rear direction of the Western style toilet is
This is because the Western-style toilet 1 is made of earthenware and the positional accuracy of the bolt holes 32 is low.

Reference numeral 38 in FIG. 5 denotes a water-passing member called a distributor. The distributor 38 supplies the water in the low tank 2 to the rim on the upper edge of the toilet bowl 19, and is connected to a float valve outlet 39 at the lower end of the low tank 2.

[0012]

As shown in FIG. 2, the work of installing the cover box 30 on the rear upper surface of the Western-style toilet 1 is usually carried out by one worker holding the cover box 30.
The cover box 30 is slowly placed on the rear upper surface so that the bolts 31 enter the bolt holes 32. However, the cover box 30 is quite heavy (usually 20 to 25k).
As described above with g), since the positional accuracy of the bolt holes 32 is low as described above, it is difficult to insert the bolts 31 into the bolt holes 32. In this case, if the cover box 30 is lowered onto the rear upper surface of the Western-style toilet while the bolts 31 are obliquely inserted into the bolt holes 32, the resin bolts 31 may be broken. Particularly, the bolt 31 is set to be long (usually 50 to 80 mm) so that the cover box 30 can be fixed even if the thickness of the rear upper surface of the Western-style toilet 1 is different. It is easy to be inserted at an angle.

It is an object of the present invention to solve such a problem and to provide a structure in which a cover box can be easily installed on a rear upper surface of a Western-style toilet.

Another object of the present invention is to prevent breakage of bolts for attaching the cover box to a Western-style toilet.

[0015]

According to the present invention, there is provided a cover box installation structure in which a cover box is installed on a rear upper surface of a Western-style toilet, and a support material of the cover box is fixed to the rear upper surface of the Western-style toilet with bolts. The cover box is installed by engaging the cover box with the support material.

In such a cover box installation structure, a support member separate from the cover box is fixed to the rear upper surface of the Western-style toilet, and the cover box is installed on the support member. The material can be made of synthetic resin with high dimensional accuracy, and the cover box can be easily attached to the support material. Since the supporting material is considerably lighter than the cover box,
Even a human worker can easily fix it to the rear upper surface of the Western style toilet.

According to the present invention, a cover box can be attached to the support material by, for example, a concave-convex engagement. Further, the cover box can be attached to the support material by engagement of the claw-shaped portions, and can also be attached by screws.

[0018] In the present invention, the cover box may be one of the third to fifth embodiments.
As shown in the figure, it is suitable to be applied to a case where a low tank and various electric components are built in. When installing a box, it can also be adopted as an installation structure of this toilet seat box.

According to another aspect of the present invention, there is provided a cover box installation structure in which a cover box is fixed on a rear upper surface of a Western-style toilet with bolts, and the bolts are vertically inserted through a rear portion of the Western-style toilet. Is inserted from above, and a nut is fastened to the bolt from below, and the nut has an upper extension inserted into the bolt hole.

In the installation structure of the cover box, the length of the bolt can be shortened by an amount corresponding to the provision of the upper extension on the nut, and the bolt is inserted into the bolt hole when the cover box is mounted on the upper surface of the rear part of the Western style toilet. The bolt can be easily inserted into the bolt, and the bolt can be prevented from being inclined and broken.

Note that the cover box installation structure of this alternative embodiment can also be applied to the mounting of the support material on the rear upper surface of a Western-style toilet.

A cover box installation structure according to still another aspect of the present invention is a structure in which a cover box is fixed to a rear upper surface of a Western-style toilet with bolts, and the bolt penetrates vertically through a rear portion of the Western-style toilet. It is characterized in that it is inserted from below into a bolt hole and is screwed into a nut provided in the cover box.

In this installation structure of the cover box, the cover box is placed on the rear upper surface of the Western-style toilet and then the cover box is fixed to the bolt hole of the Western-style toilet through a bolt from below. It can be easily placed on the upper surface.

In this case, if a lower extension is provided on the nut and this lower extension is inserted into the bolt hole, the length of the bolt can be shortened accordingly.

This embodiment can also be applied to the mounting of the support material on the rear upper surface of the Western-style toilet.
