Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a wall drain type toilet bowl having a rear end face fixed to a wall face and connected to a drain pipe provided on the wall face. The aim is to improve the aesthetics.

[0002]

2. Description of the Related Art In a conventional wall drain type toilet, when a rear end face is attached to a wall surface, fixing by a bolt of the toilet bowl and connection of a discharge port formed in the rear end face of the toilet bowl to a drain pipe of the wall face are simultaneously performed. It did not go away.

[0003]

Since it is necessary to match both the position where the fixing bolt is inserted into the toilet and the position of the outlet with respect to the drain pipe, it is difficult to position the toilet.

[0004] When connecting the outlet of the toilet to the drain pipe on the wall, a gasket for preventing water leakage is usually interposed between the two, but the state of the gasket cannot be visually observed during the fixing work of the toilet. It is difficult to grasp the state of the seal between the drain pipe and the outlet. Moreover, since the toilet bowl is a baked product, dimensional errors are inevitable.
We had to rely on the experience and intuition of the workers.

[0005] If water leaks after the toilet is fixed, the toilet must be removed and the fixing work must be restarted from the beginning, and therefore the work efficiency is extremely poor.

[0006] When the maintenance is performed, the fixing of the toilet must be similarly removed, so that the fixing operation must be performed again, which is troublesome.

Furthermore, the conventional wall drain type toilet bowl cannot be said to be necessarily excellent in aesthetics because the tip of the fixing bolt protruding from the rear end wall surface is observed. In addition, a cosmetic cap nut is attached to the tip of the fixing bolt for improving aesthetics. In this case, it is necessary to adjust the protrusion dimension of the bolt so as not to be excessive or insufficient.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a novel wall drainage toilet structure and a mounting structure thereof. A feature of the wall drainage toilet bowl adopted by the present invention is that a storage space is formed between an intermediate partition wall forming a toilet bowl and a drainage channel and a rear end wall,
An upper opening communicating with the storage space is formed on a rear upper surface of the toilet, a discharge port is provided in the intermediate partition wall, and a rear opening and a toilet for inserting a pipe connecting a drain pipe provided on a wall surface and the discharge port. Is provided on the rear end wall to allow a bolt for fixing the bolt to the wall surface to protrude into the storage space.

A water supply port for supplying cleaning water can be provided in the intermediate partition.

On the other hand, a feature of the mounting structure of the wall-drainable toilet according to the present invention configured as described above is that the rear end face of the toilet bowl is fixed to the wall surface by bolts that penetrate the rear end wall and project into the storage space. Then, a drain pipe provided on a wall surface and a discharge port provided on an intermediate partition are connected by a flexible pipe.

In the mounting structure, a cover that covers an upper opening formed on the rear upper surface of the toilet and that communicates with the storage space can be detachably mounted, and a toilet seat or a toilet lid can be pivotally attached to the cover.

Further, a water supply control device can be stored in the storage space.

Further, a configuration may be adopted in which a water supply pipe connecting the water supply pipe on the wall surface and the water supply port of the intermediate partition wall is housed in a storage space, and a part or all of the water supply pipe is covered with a cover.

[0014]

An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, for example, the wall drainage toilet 1 according to the present invention has a storage space between an intermediate partition 10 forming a toilet bowl 7 and a drainage channel 9 and a rear end wall 4 fixed to a wall W. 2 is formed, and an upper opening 3 communicating with the storage space 2 is formed on the rear upper surface of the toilet 1.

The rear end wall 4 has an outlet 12 for the intermediate partition 10.
A rear opening 6 for inserting a pipe P connecting the drainage pipe 20 provided on the wall surface W and a bolt 30 for fixing the toilet bowl 1 to the wall surface W for projecting into the storage space 2. An insertion portion 5 is formed.

In the example of FIG. 1, the rear opening 6 facing the drain pipe 20 is formed by a cutout formed by cutting a predetermined range from the upper end of the rear end wall 4, and the insertion portion 5 of the bolt 30 is formed by the rear end wall 4. And a through hole formed on the left and right of the notch. Also, an upper opening 3 on the rear upper surface of the toilet 1 and a rear end wall 4
The rear opening 6 is continuous with the upper edge of the rear end.

In the toilet 1 constructed as described above, as shown in FIG. 2, a bolt 30 previously attached to and protruded from the wall surface W is inserted into the insertion portion 5 of the rear end wall 4 to enter the storage space 2. The rear end surface 4a can be fixed to the wall surface W by projecting and screwing and tightening the nut 31 thereto.

After the toilet 1 is fixed, the drain pipe 20 facing the rear opening 6 of the rear end wall 4 and the discharge port 12 of the intermediate partition 10 are connected by a pipe P. If the opening area of the rear opening 6 is formed sufficiently large, the drain pipe 20 can be reliably brought into the storage space 2 even if there is some dimensional error.
Also, by using the flexible pipe P, the positioning of the toilet 1 with respect to the drain pipe 20 can be substantially omitted. In addition, the height position of the drain pipe 20 with respect to the toilet 1 is variously changed according to the washing method of the toilet 1, for example, a siphon type, a wash-off type, a blow-out type, etc. It has the advantage that it is easy to respond.

The toilet fixing work and the pipe connection work are performed as follows.
Both can be performed in the storage space 2 through the upper opening 3 of the toilet 1. Then, since the toilet 1 is fixed first and then connected to the drain pipe 20, when the connection state of the pipes needs to be corrected, the correction work can be easily performed without removing the toilet.

The storage space 2 can be used for storing various devices attached to the toilet 1. In the drawing, the rim water passage 8 provided on the intermediate partition 10 of the toilet 1 is shown.
And a water supply pipe 40 provided on the wall surface W
The case where the water supply control means such as the electromagnetic flash valve 13 for communicating with the water supply device is provided is illustrated. Other devices that can be disposed in the storage space 2 include a hot water washing device, a hot water tank, a hot air fan, a deodorizing device, and a control device for these electric devices.

【Example】

[First Embodiment] A wall drain type toilet 1 shown in FIG.
The storage space 2 is formed between the storage space 2 and the intermediate partition 10, and the interior can be viewed from the upper opening 3. The rear end wall 4 has a rear opening 6 formed of a notch for facing a drain pipe and an insertion portion 5 formed of a through hole for inserting the fixing bolt 30. A water supply port 11 and a discharge port 12 communicating with the rim water passage 8 are provided in an intermediate partition 10 that forms a part of each of the toilet bowl 7 and the drain passage 9.

FIG. 2 shows an example of the mounting structure of the wall drain type toilet 1. In order to fix the toilet bowl 1 to the wall surface W, a bolt 30 is attached to the wall surface W in advance so as to protrude, the toilet bowl 1 is held, and the bolt 30 is inserted through the insertion portion 5 of the rear end wall 4. Next, the nut 31 is screwed into the bolt 30 protruding into the storage space 2 and tightened to fix the toilet 1 to the wall surface W.

After the toilet 1 has been fixed in this way, the discharge port 12 of the intermediate partition 10 and the drain pipe 2
Make a pipe connection to 0. As the connecting pipe P, a flexible pipe such as a synthetic resin pipe having a bellows portion formed in the middle as shown in the figure is used. By setting the opening area of the rear opening 6 to be sufficiently large and making the connecting pipe P flexible, even if there are some errors in the external dimensions of the toilet 1 and the mounting position of the drain pipe 20, etc. The piping connection operation can be easily and reliably performed without any hindrance.

After the pipe connection between the discharge port 12 and the drain pipe 20,
If the connection state is poor and water leakage or the like occurs, the pipe connection work is redone through the upper opening 3. At this time, since it is not necessary to remove the toilet 1 from the wall surface W, the repair work is simple.

Subsequently, necessary devices are arranged in the storage space 2. In this example, the electromagnetic flash valve 13 that connects the water supply port 11 formed in the intermediate partition 10 and the water supply pipe 40 provided on the wall surface W is installed in the storage space 2. Although not shown, when the operation of the electromagnetic flash valve 13 is controlled by a remote controller or a human body detection device installed outside the toilet 1, a control device may be provided in the storage space 2.

The upper opening 3 of the toilet 1 is provided with a suitable cover 14
In this embodiment, the toilet seat 1 is attached to the cover 14.
5 and the toilet lid 16 were pivotally connected. Further, as shown in the drawing, by providing the concave portion 14 a on the lower surface side of the cover 14, a portion of the equipment disposed in the storage space 2 that projects above the upper surface of the toilet 1 can be stored.

In this embodiment, a water supply port 11 for introducing washing water into the rim water passage 8 is provided in the intermediate partition 10, and an electromagnetic flash valve 13 and a water supply pipe are stored in the storage space 2 to cover them. Since the structure covered with 14 is adopted, the aesthetic appearance is excellent, and strict alignment between the toilet and the water supply pipe is not required at all. Further, if the water supply pipe is made flexible, the workability can be further improved.

[Second Embodiment] In the present embodiment, as shown in FIG. 3, the rear opening 6 of the toilet 1 is constituted by a window or opening formed in the rear end wall 4. Such a configuration improves the strength of the rear end wall 4 as compared with the first embodiment. However, the first embodiment is considered to be slightly more advantageous in terms of manufacturing efficiency.

[Third Embodiment] In the embodiment shown in FIG. 4, the bolt insertion portion 5 formed in the rear end wall 4 of the toilet 1 is notched instead of a through hole. With this configuration, the degree of adjustment in the left-right direction of the mounting position on the wall surface of the toilet 1 can be increased. According to the present invention, there is almost no need to consider the positioning of the toilet with respect to the drainpipe. Therefore, by adopting the configuration of this embodiment, when a plurality of toilets are installed on the same wall surface, the interval between the toilets is reduced. Adjustment becomes easy.

Fourth Embodiment FIG. 5 shows an embodiment in which a pedestal 18 is provided on the lower surface of the toilet 1. In the toilet 1 according to the present invention, the rear end wall 4 is fixed to the wall with bolts. In order to support the user's load and the weight of the toilet 1, the pedestal 18 as shown is provided as an auxiliary. Is also possible.

[0031]

According to the present invention, since the work of fixing the wall surface of the toilet and the work of connecting to the drain pipe can be performed separately, if the connection state of the drainage pipe is poor and water leakage occurs, the toilet bowl is removed. It is possible to redo only the pipe connection work without any trouble. In addition, the maintenance work can be performed in the storage space through the upper opening, so that in this case, it is unnecessary to remove the toilet.

The connection between the drainage pipe on the wall and the outlet of the toilet using a flexible pipe makes it extremely easy to position the toilet with respect to the wall. Moreover, since the pipe connection work can be performed from the indoor side in the storage space of the toilet bowl,
Workability is improved.

Since the bolts and nuts for fixing the toilet are stored in the storage space, they are not observed from the outside after construction. Therefore, the aesthetic appearance is improved, and the conventional cap nut for cosmetics is not required, so that it is not necessary to adjust the protrusion amount of the bolt.

A water supply port for supplying washing water is provided in the intermediate partition wall, a pipe for connection to the water supply pipe is stored in the storage space, and a part or all of the pipe is covered with a cover for covering the upper opening. In addition to improving the aesthetics, it is not necessary to strictly position the toilet bowl with respect to the water supply pipe.
