Description

The present invention relates to a toilet device.

In conventional toilet devices, a flushing water supply device for supplying flushing water to the toilet bowl is installed in the toilet bowl (see, for example, Patent Document 1). A through hole is provided at the rear of the toilet device for drawing a water supply hose into the outer peripheral wall of the toilet bowl. The end of the water supply hose is drawn into the storage section from this through hole, and then connected to the connection part of the flushing water supply device.

JP 2009-191500 A

However, in conventional toilet devices, in order to easily connect the water supply hose to the connection part, the connection part needs to be located above the toilet. As a result, conventional flush water supply devices have a problem in that the height of the connection part is increased, making the flush water supply device taller.

The present invention was developed in consideration of the above problems, and aims to provide a toilet device that can keep the height of the flushing mechanism low.

To achieve the above object, the present invention provides a toilet device (e.g., toilet device 1, 101, 201 described later) that includes a flushing mechanism (e.g., flushing mechanism 9, 109, 209 described later) and a toilet part (e.g., toilet part 2, 202 described later) that has a storage part (e.g., storage part 4, 204 described later) that stores the flushing mechanism part at its rear part, the storage part having a first opening (e.g., first opening 42, 142, 242 described later) through which a first water supply pipe (e.g., first water supply pipe 92, 192, 292 described later) is inserted, and the flushing mechanism part is formed at its rear part facing the first opening and has a first connection part (e.g., first connection part 91a, 191a, 291a described later) to which the first water supply pipe can be connected from outside the first opening.

It is also preferable that the cleaning mechanism further has a second connection part (e.g., second water supply pipe connection part 91c, 191c, 291c described later) formed at the rear thereof facing the first opening and capable of connecting a second water supply pipe (e.g., second water supply pipe 96, 196, 296 described later) disposed within the storage part from outside the first opening.

It is also preferable that the storage section further includes a water ingress suppression means (e.g., water ingress suppression means 44 described below) that is disposed in the first opening and is configured to allow the water supply pipe to be inserted therethrough.

It is also preferable that the storage section further has a reinforcing wall (e.g., reinforcing walls 43 and 243 described below) extending forward from the lower portion of the first opening.

The storage section also preferably has a second opening (e.g., second opening 245 described below) formed on the rear wall surface below the first opening and through which a drainage pipe is inserted, and the reinforcing wall is preferably connected between the first opening and the second opening.

The present invention provides a toilet device that allows the height of the flushing mechanism to be kept low.

In the following description, the front-to-back direction is the front-to-back direction when viewed from a person sitting on the toilet seat (not shown) of the toilet device 1, the left-to-right direction is the left-to-right direction when viewed from a person sitting on the toilet seat, and the up-to-down direction is the vertical direction from the toilet bowl 2 to the toilet lid 5.

The toilet device 1 comprises a ceramic toilet portion 2, a toilet seat (not shown), a toilet cover 5, a base plate 6, a functional portion 7, a cover portion 8, and a flushing mechanism portion 9.

The toilet seat (not shown) and toilet lid 5 are attached above the toilet bowl 2 so that they can rotate relative to the toilet bowl 2.

The toilet bowl 2 is comprised of a toilet bowl 3 formed in a downward cone shape at the front side, and a storage section 4 formed in a downward recess at the rear side. The entire surface of the toilet bowl 2 is made of ceramic. There are no particular limitations on the shape of the toilet bowl 2, and various standards can be applied.

A rim portion 31 that is generally rectangular in cross section is formed above the toilet bowl 3. A drainage channel 33 that is generally S-shaped in cross section is formed below the toilet bowl 3, with one end connected to a drainage connection pipe 34. The inside of the toilet bowl 3 is cleaned with cleaning water supplied from the cleaning mechanism 9.

A connection opening 33a for a jet nozzle 951 (described later) is formed in the middle of the drainage channel 33. A drain connection pipe 34 is connected to the downstream end 33b of the drainage channel 33. A reinforcing wall 43 (described later) is connected to the downstream wall surface 36 of the drainage channel 33. The drainage channel 33 is supplied with flush water flowing in from the toilet bowl 3 and flush water from the jet nozzle 951.

The storage section 4 has a first opening 42 formed in the rear wall surface 41 so as to penetrate from the inside to the outside, and a reinforcing wall 43 formed from the rear wall surface 41 toward the front wall surface.
A base plate 6 is installed above the storage unit 4, and a functional unit 7 and a part of a cleaning mechanism unit 9 fixedly supported by the base plate 6 are disposed within the storage unit 4.

The first opening 42 of the storage unit 4 is provided so that the first water supply pipe 92, which supplies cleaning water to the cleaning mechanism 9, can be inserted therethrough. The size of the first opening 42 is set so that an operator can insert both hands into the opening to connect and lock the first water supply pipe 92, which will be described later, to the cleaning mechanism 9, and the second water supply pipe 96, which will be described later, to the cleaning mechanism 9. The first opening 42 is formed in a substantially elliptical shape on the rear wall surface 41, extending toward the second water supply pipe 96 (for example, to the left in FIG. 4).

One end of the reinforcing wall 43 of the storage section 4 is connected to the rear wall surface 41 of the storage section 4 (e.g., the lower side of the paper in FIG. 7), and the other end is connected to the downstream wall surface 36 of the drainage channel 33 (e.g., the upper side of the paper in FIG. 7).

As shown in FIG. 8, the first opening 42 of the storage section 4 in this embodiment may be provided with a water ingress suppression means 44 that fits into the first opening 42 .
The water ingress suppression means 44 has a generally rectangular insertion hole 441 formed in the center thereof, through which the first water supply pipe 92 can be inserted (see FIG. 9 ). The water ingress suppression means 44 can also be attached to the first opening 42 while the first water supply pipe 92 remains connected to the cleaning mechanism 9.

The water ingress prevention means 44 prevents water from entering the storage section 4 from the outside and improves the strength of the first opening 42. When a bathroom and a toilet are placed in the same space, the water ingress prevention means 44 can prevent water droplets from a shower or the like from entering the interior, so when applying the toilet device 1 of this embodiment to a toilet in a residence or hotel overseas, it is preferable to use this water ingress prevention means 44 together.

Returning to FIG. 2, the base plate 6 is disposed on the upper surface of the storage unit 4. The functional unit 7 and the cleaning mechanism unit 9 are fixedly supported on the base plate 6. Part of the base plate 6 is provided with insertion holes through which the functional components and the cleaning mechanism unit 9 can be appropriately inserted.

The functional section 7 is composed of various functional components, such as a power supply unit (not shown) fixed to the base plate 6, an electric opening and closing unit for the toilet seat and toilet lid, a sanitary washing unit, a warm air drying unit, control circuit boards for each unit, and various piping. A cover section 8 is installed on the functional section 7 from above.

The flushing mechanism 9 is composed of a flushing water supply unit 91, a water supply pipe 92, a rim nozzle (first water outlet) 93, a second water outlet (not shown), a nozzle pipe 94, a booster (pressure accumulator) 95, and a second water supply pipe 96. The flushing mechanism 9 is disposed on the rear side of the base plate 6. The flushing mechanism 9 supplies flushing water supplied from a water pipe to the inside of the toilet bowl 3 from the rim nozzle 93 and the second water outlet, and also supplies water from a jet nozzle 951 to the inside of the drainage channel 33.

One end 92a of the first water supply pipe 92 is connected to the supply port 10a of the stopcock member 10 that is connected to the water pipe, and the other end 92b is connected to the first water supply pipe connection part (first connection part) 91a of the cleaning water supply part 91 described later. On both ends of the first water supply pipe 92, a device or the like that can be attached and detached to the supply port 10a of the stopcock member 10 and the first water supply pipe locking part 91b installed on the first water supply pipe connection part 91a can be appropriately attached.

The rim nozzle 93 is disposed inside the rim portion 31 above the toilet bowl 3. The rim nozzle 93 supplies flushing water supplied from a nozzle pipe 94 connected to one end 93a to the toilet bowl 3 from a downstream opening 93b.

The nozzle pipe 94 has a bifurcated branch pipe (not shown) in the middle of the flow path. This bifurcated branch pipe branches the nozzle pipe 94 into a flow path toward the rim nozzle 93 and a flow path toward the second water outlet. The nozzle pipe 94 sends wash water supplied from one end to the rim nozzle 93 and the second water outlet.

The pressure accumulator 95 stores a portion of the flushing water supplied from the second water supply pipe 96, and sprays pressurized flushing water from the tip of the jet nozzle 951 into the drainage channel 33 in accordance with the timing of flushing the toilet bowl 3.

The cleaning water supply unit 91 comprises a first water supply pipe connection portion 91a to which the other end 92b of the first water supply pipe 92 is connected, a first water supply pipe locking portion 91b that locks the first water supply pipe 92 to the first water supply pipe connection portion 91a, a nozzle pipe connection portion (not shown) to which the nozzle pipe 94 is connected, a nozzle pipe locking portion (not shown) that locks the nozzle pipe 94 to the nozzle pipe connection portion, a second water supply pipe connection portion (second connection portion) 91c to which the second water supply pipe 96 is connected, and a second water supply pipe locking portion 91d that locks the second water supply pipe 96 to the second water supply pipe connection portion 91c.
The flush water supply section 91 supplies flush water supplied from a first water supply pipe 92 to the rim nozzle 93 , the second water discharge section and the pressure accumulator 95 .

The first water supply pipe connection part 91a is formed on the rear side of the cleaning water supply part 91, on the lower side of the base plate 6, facing the first opening 42 side. The other end part 92b of the first water supply pipe 92 is connected to the first water supply pipe connection part 91a. The water supply pipe connection part 91a is installed in a position visible from the first opening 42, and the first water supply pipe 92 can be directly connected from outside the storage part 4.

The first water supply pipe locking portion 91b locks the circumference of the other end 92b of the first water supply pipe 92 connected to the first water supply pipe connection portion 91a, or the tip thereof, with a fastener such as a clip (not shown). When releasing the locking state by the first water supply pipe locking portion 91b, the first water supply pipe 92 can be removed by operating a release lever 92c on the first water supply pipe 92 side.
The removal of the first water supply pipe 92 is not limited to the release action using the release lever 92c, and various release mechanisms can be applied.

The nozzle pipe connection part (not shown) is formed with a water inlet facing downward on the front side of the cleaning water supply part 91. One end of the nozzle pipe 94 is connected to the nozzle pipe connection part.

The nozzle pipe locking portion (not shown) is equipped with a fastener similar to that of the water supply pipe locking portion. This allows the nozzle pipe 94 to be locked and unlocked.

The second water supply pipe connection portion 91c is provided adjacent to the first water supply pipe connection portion 91a. The second water supply pipe connection portion 91c has a water supply port (not shown) facing downward. One end portion 96a of the second water supply pipe 96 is connected to the second water supply pipe connection portion 91c. The second water supply pipe connection portion 91c is installed in a position where a portion of it can be seen from the first opening 42.

The second water supply pipe locking portion 91d is provided with a clip-shaped locking portion or the like on the second water supply pipe connection portion 91c. The second water supply pipe 96 can be locked and unlocked by sliding the clip or the like. It is also possible to use a fastener similar to that of the first water supply pipe locking portion 91b.

The construction procedure for connecting the first water supply pipe 92 in the toilet device 1 having the above configuration will be explained with reference to Figure 6.

First, the base plate 6 to which the functional section 7 and the cleaning water supply section 91 are attached is attached to the storage section 4. Next, the nozzle pipe 94 is connected to the nozzle pipe connection section of the cleaning water supply section 91 and locked by the nozzle pipe locking section.
Next, one end of the second water supply pipe 96 is connected from the first opening 42 to the second water supply pipe connection portion 91c with the end facing upward, and is locked by the second water supply pipe locking portion 91d.
Next, the other end 92b of the first water supply pipe 92, one end of which is connected to the water stop valve member 10 that is directly connected to the water pipe, is connected to the first water supply pipe connection part 91a and locked by the first water supply pipe locking part 91b. After that, the water ingress suppression means 44 is attached to the first opening 42 with the first water supply pipe 92 inserted through the insertion hole 441.
Each of the above steps is carried out in a factory, and the toilet apparatus 1 assembled to this state is transported to the installation site of the toilet. The toilet apparatus 1 is then connected to the stop valve member 10 and the drain pipe 35. As a result, a flow path for flushing water of the toilet portion 2 is formed in the toilet apparatus 1, from the stop valve member 10 to the drain pipe 35.

In addition, in the toilet device 1 of this embodiment, as shown in FIG. 9, it is also possible to connect the other end 92b of the first water supply pipe 92 to the first water supply pipe connection portion 91a with the water ingress suppression means 44 already attached to the first opening 42.

[Modification]
Here, a modified example of this embodiment will be described with reference to Fig. 10. Fig. 10 is a rear view showing the first opening 142 of the toilet apparatus 101 according to the modified example of this embodiment.
In a modification of this embodiment, the first opening 142 of the toilet device 101 is machined into a substantially perfect circle shape as shown in Fig. 10. In this modification, a water supply pipe connection part 91a and a second water supply pipe connection part 91c are provided at positions facing the first opening 142. By machining the shape of the water intrusion suppression means 44 shown in Fig. 9 to match the shape of the first opening 142, it is possible to use a lid part in this modification as well.

The first opening 142 of this modification has a larger hole area formed in the rear wall surface 141 compared to the first opening 42 of the first embodiment, but since the storage section is provided with a reinforcing wall (not shown), deformation is suppressed unless excessive pressure is applied to the rear wall surface 141. In addition, the nearly circular opening of the first opening 142 of this modification can be formed more easily than the nearly elliptical hole of the first opening 42 of the first embodiment.

The toilet device 1 of this embodiment described above provides the following advantages:

The toilet device 1 according to this embodiment is configured to include a flushing mechanism 9 and a toilet portion 2 having, at its rear, a housing portion 4 for housing the flushing mechanism 9 .
More specifically, the storage section 4 of the toilet device 1 is formed in a rear wall surface 41 thereof, and has a first opening 42 through which a first water supply pipe 92 is inserted. The flushing mechanism section of the toilet device 1 is formed in a rear portion thereof facing the first opening 42, and has a first connection section 91a to which the first water supply pipe can be connected from outside the first opening.
As a result, the first water supply pipe 92 of the present invention can be connected to the first water supply pipe connection part 91a from outside the storage part 4. Therefore, in the cleaning mechanism part 9 of the present invention, unlike the conventional cleaning mechanism part, it is not necessary to connect the water supply pipe and the connection part inside the cleaning mechanism part 9, and the height can be reduced.
Therefore, according to this embodiment, a toilet apparatus 1 can be provided that allows the height of the flushing mechanism part 9 to be kept low.
Furthermore, according to this embodiment, the height of the flushing mechanism 9 is kept low, which makes it possible to reduce the height of the toilet apparatus 1 itself. As a result, the entire toilet apparatus 1 can be made compact.

In addition, the cleaning mechanism unit 9 in this embodiment is configured to further have a second connection portion 91c formed at its rear portion opposite the first opening 42 and to which a second water supply pipe 96 arranged within the storage unit 4 can be connected from outside the first opening 42.
More specifically, the shape of the first opening 42 is a generally elliptical shape extending toward the second water supply pipe 96. As a result, while it was impossible to connect the second water supply pipe and the second water supply pipe connecting part with a conventional through hole, the first opening 42 of the present invention makes this possible.
Therefore, according to this embodiment, by enlarging the opening on only one side, an opening having a region necessary for connecting the second water supply pipe 96 and the second water supply pipe connecting portion 91c is formed. As a result, according to this embodiment, the size can be minimized.
According to the present embodiment, the shape of the first opening 42 can be changed to a substantially perfect circle. In this case, it is easier to form the opening than if it were a substantially ellipse.

Moreover, the storage section 4 according to this embodiment is configured to have a water ingress suppression means 44 that is disposed in the first opening 42 and is formed so that the water supply pipe can be inserted therethrough. This makes it possible to prevent water from ingressing through the first opening 42 when the toilet device 1 is flushed.
Therefore, according to this embodiment, the present invention can also be applied to toilets installed in shower room spaces in overseas locations, hotels, etc.
Furthermore, according to this embodiment, the water infiltration suppression means 44 also functions as a reinforcing material for the first opening 42, making it possible to maintain the strength of the rear wall surface 41.

Moreover, the storage section 4 according to this embodiment is configured to further include a reinforcing wall 43 extending forward from the lower portion of the first opening 42. This reinforcing wall 43 is formed integrally with the rear wall surface 41 and the toilet section 2. This allows the strength of the rear wall surface 41 to be maintained compared to conventional toilet devices that do not include a reinforcing wall.
Therefore, according to this embodiment, the rear wall surface 41 of the storage section 4 can be strengthened by the reinforcing wall 43, so deformation of the rear wall surface 41 can be suppressed. As a result, the size of the opening (through hole) can be made larger than that of a conventional toilet device. This makes it possible to work with one's hand inserted into the first opening 42, and facilitates the connection and locking work of the first water supply pipe 92 and the second water supply pipe 96.

[Second embodiment]
Next, a toilet device 201 according to a second embodiment of the present invention will be described with reference to Figs.
Fig. 11 is a top view showing a toilet apparatus 201 according to the second embodiment. Fig. 12 is a rear view showing the toilet apparatus 201 according to the second embodiment.

A toilet portion 202 of a toilet device 201 differs from the toilet device 1 of the first embodiment in that it is adapted to a so-called wall drainage toilet.
12, below the first opening 242 in the rear wall surface 241 of the toilet portion 202 (i.e., below the reinforcing wall 243), a second opening 245 through which the drain connection pipe 234 for wall piping is inserted is provided. One end of the drain connection pipe 234 is connected to the downstream end 233b of the drainage channel 233, and the other end is inserted through the second opening 245 and connected to a drain pipe (not shown) installed behind the toilet.

In the toilet device 201 having the above configuration, the construction operation for connecting the first water supply pipe 292 and the second water supply pipe 296 is performed in the same manner as in Figure 6 of the first embodiment.

The installer inserts his hand through first opening 242 and connects the other end of second water supply pipe 296, which has been previously connected to pressure accumulator 295, to second water supply pipe connecting portion 291c. Then, the other end of second water supply pipe 296 is engaged with second water supply pipe connecting portion 291c using second water supply pipe engaging portion 291d.
Next, the other end 292b of the first water supply pipe 292, which has been previously connected to the stopcock member 210, is connected to the water supply pipe connection part 291a. After that, the other end 292b of the water supply pipe 292 is locked to the first water supply pipe connection part 291a using the water supply pipe locking part 291b. After that, a lid is fitted into the first opening 242, and the drain connection pipe 234 of the toilet apparatus 201 is connected to a drain pipe provided behind the toilet apparatus 201.

The toilet device 201 of this embodiment described above provides the following advantages.
The storage section 204 of the toilet device 201 of this embodiment is configured to further include a second opening 245 formed in a rear wall surface 241 thereof below the first opening 242. In addition, the reinforcing wall 243 is configured to be connected between the first opening 242 and the second opening 245.
Therefore, according to this embodiment, the toilet device 201 can be applied to a wall-piped toilet in a building.
Furthermore, in the toilet device 201 of this embodiment, the reinforcing wall 243 ensures the strength of the rear wall surface 241, so that the problem of deformation is unlikely to occur even in a toilet made of ceramic.

The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of the present invention are included in the present invention.
For example, although the toilet apparatus of the above-described embodiment has been illustrated as being installed on the floor of a building in a preassembled state in a factory, it is also possible to assemble the toilet apparatus at the installation site.
