[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-191500 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional toilet devices, the connection part needs to be located above the toilet bowl in order to make it easier to connect the water supply hose to the connection part, which means that the height of the conventional flush water supply device increases by the height of the connection part, which creates the problem of the flush water supply device becoming taller.

[0005] The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a toilet apparatus that can keep the height of a flushing mechanism low. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a toilet device (for example, toilet device 1, 101, 201 described later) comprising a flushing mechanism unit (for example, flushing mechanism unit 9, 109, 209 described later) and a toilet unit (for example, toilet unit 2, 202 described later) having a storage unit (for example, storage unit 4, 204 described later) at its rear for storing the flushing mechanism unit, wherein the storage unit is formed in its rear wall surface (for example, rear wall surface 41, 141, 241 described later) and has a first opening (for example, first opening 42, 142, 242 described later) through which a first water supply pipe (for example, first water supply pipe 92, 192, 292 described later) is inserted, and the flushing mechanism unit is formed in its rear portion opposite the first opening and has a first connection unit (for example, first connection unit 91a, 191a, 291a described later) to which the first water supply pipe can be connected from outside the first opening.

[0007] It is also preferable that the cleaning mechanism further has a second connection portion (e.g., second water supply pipe connection portion 91c, 191c, 291c described later) formed at its rear portion opposite the first opening and capable of connecting a second water supply pipe (e.g., second water supply pipe 96, 196, 296 described later) arranged within the storage portion from outside the first opening.

[0008] Preferably, the storage section further includes a water ingress suppression means (for example, water ingress suppression means 44 described later) that is disposed in the first opening and is formed so that the water supply pipe can be inserted therethrough.

[0009] Preferably, the storage section further has a reinforcing wall (for example, reinforcing walls 43, 243 described below) extending forward from the lower portion of the first opening.

[0010] Furthermore, it is preferable that the storage section further has a second opening (for example, second opening 245 described later) formed on its rear wall surface below the first opening and through which a drainage pipe is inserted, and that the reinforcing wall is connected between the first opening and the second opening. [Effects of the Invention]

In the following description, the front-to-back direction as seen from a person sitting on the toilet seat (not shown) of the toilet device 1 is referred to as the front-to-back direction, and the left-to-right direction as seen from a person sitting on the toilet seat is referred to as the left-to-right direction. Also, the up-to-down direction is the direction perpendicular to the toilet bowl 2 toward the toilet lid 5.

[0015] The toilet device 1 comprises a ceramic toilet portion 2, a toilet seat (not shown), a toilet lid 5, a base plate 6, a function portion 7, a cover portion 8, and a flushing mechanism portion 9.

[0016] A toilet seat (not shown) and a toilet lid 5 are attached above the toilet bowl 2 so as to be rotatable relative to the toilet bowl 2.

[0017] The toilet bowl 2 comprises a toilet bowl 3 formed in a downward-facing cone shape at the front side, and a storage section 4 formed in a downward-facing recess at the rear side. The entire surface of the toilet bowl 2 is made of ceramic. There are no particular restrictions on the shape of the toilet bowl 2, and various standards can be applied.

[0018] A rim portion 31 having a generally rectangular cross section is formed above the toilet bowl 3. A drainage channel 33 having a generally S-shaped 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 portion 9.

[0019] A connection opening 33a for a jet nozzle 951, which will be described later, is formed in the middle of the drainage channel 33. A drain connection pipe 34 is connected to a downstream end 33b of the drainage channel 33. A reinforcing wall 43, which will be described later, is connected to a downstream wall surface 36 of the drainage channel 33. Flush water flowing in from the toilet bowl 3 and flush water from the jet nozzle 951 are supplied to the drainage channel 33.

[0020] 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.

[0021] The first opening 42 of the storage unit 4 is provided so that a first water supply pipe 92 (described later) that supplies cleaning water to the cleaning mechanism 9 can be inserted therethrough. The size of the first opening 42 is set to allow an installer to insert both hands into the opening and perform the connecting and locking operations for the first water supply pipe 92 (described later) and the cleaning mechanism 9, and the connecting and locking operations for the second water supply pipe 96 (described later) and the cleaning mechanism 9. The first opening 42 is formed in a substantially elliptical shape on the rear wall surface 41 and extends toward the second water supply pipe 96 (for example, to the left in FIG. 4 ).

[0022] The reinforcing wall 43 of the storage section 4 has one end connected to the rear wall surface 41 of the storage section 4 (for example, the lower side of the paper in Figure 7), and the other end connected to the downstream wall surface 36 of the drainage channel 33 (for example, the upper side of the paper in Figure 7).

[0023] As shown in FIG. 8, the first opening 42 of the storage section 4 of this embodiment can be provided with a water ingress prevention means 44 that fits into the first opening 42 . The water intrusion suppression means 44 has a substantially 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 intrusion 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.

[0024] The water ingress prevention means 44 prevents water from entering the storage section 4 from the outside, and also improves the strength of the first opening 42. The water ingress prevention means 44 can prevent water droplets from a shower or the like from entering the interior when a bathroom and a toilet are placed in the same space, 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.

[0025] 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. Parts of the base plate 6 are provided with insertion holes through which the functional members and the cleaning mechanism unit 9 can be appropriately inserted.

[0026] 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, various piping, etc. A cover section 8 is installed on the functional section 7 from above.

[0027] The flushing mechanism 9 is made up of a flush water supply unit 91, a water supply pipe 92, a rim nozzle (first water outlet) 93, a second water outlet (not shown), 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 flush water supplied from a water pipe into the inside of the toilet bowl 3 from the rim nozzle 93 and the second water outlet, and also supplies water into the inside of the drainage channel 33 from a jet nozzle 951.

[0028] One end 92a of the first water supply pipe 92 is connected to a supply port 10a of the stop valve member 10 which is connected to a water pipe, and the other end 92b is connected to a first water supply pipe connection part (first connection part) 91a of the flush water supply part 91 which will be described later. At both ends of the first water supply pipe 92, a device or the like can be attached as appropriate to a first water supply pipe locking part 91b which is installed in the supply port 10a of the stop valve member 10 and the first water supply pipe connection part 91a.

[0029] The rim nozzle 93 is disposed inside the rim portion 31 above the toilet bowl 3. The rim nozzle 93 supplies flush water supplied from a nozzle pipe 94 connected to one end 93a to the toilet bowl 3 from a downstream opening 93b.

[0030] The nozzle piping 94 is provided with a bifurcated branch pipe (not shown) midway through its flow path. This bifurcated branch pipe causes the nozzle piping 94 to branch into a flow path toward the rim nozzle 93 and a flow path toward the second water outlet. The nozzle piping 94 sends flush water supplied from one end to the rim nozzle 93 and the second water outlet.

[0031] The pressure accumulator 95 stores a portion of the flush water supplied from the second water supply pipe 96, and sprays pressurized flush water from the tip of the jet nozzle 951 into the drainage channel 33 in accordance with the timing of flushing the inside of the toilet bowl 3.

[0032] The cleaning water supply unit 91 comprises a first water supply pipe connection portion 91a to which the other end portion 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 the first water supply pipe 92 to the rim nozzle 93 , the second water discharge section and the pressure accumulator 95 .

[0033] The first water supply pipe connection part 91a is formed behind the cleaning water supply part 91, below the base plate 6, facing the first opening 42. 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.

[0034] 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 its tip, with a fastener such as a clip (not shown). In addition, when releasing the locked state by the first water supply pipe locking portion 91b, the first water supply pipe 92 can be removed by operating the release lever 92c on the first water supply pipe 92 side. The method for removing the first water supply pipe 92 is not limited to the release operation using the release lever 92c, and various release mechanisms can be applied.

[0035] The nozzle pipe connecting part (not shown) has a water inlet formed facing downwards on the front side of the cleaning water supply part 91. One end of the nozzle pipe 94 is connected to the nozzle pipe connecting part.

[0036] The nozzle pipe locking portion (not shown) is provided with a fastener similar to that of the water supply pipe locking portion, which allows the nozzle pipe 94 to be locked and unlocked.

[0037] 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) formed 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.

[0038] The second water supply pipe locking portion 91d has a clip-shaped locking portion or the like provided on the second water supply pipe connecting portion 91c. By sliding the clip or the like, the second water supply pipe 96 can be locked and unlocked. Note that a fastener similar to that used for the first water supply pipe locking portion 91b can also be used.

[0039] The construction procedure up to the connection of the first water supply pipe 92 in the toilet apparatus 1 having the above configuration will be described with reference to FIG.

[0040] First, the base plate 6 with the functional part 7 and the cleaning water supply part 91 attached thereto is attached to the storage part 4. Next, the nozzle pipe 94 is connected to the nozzle pipe connection part of the cleaning water supply part 91 and locked by the nozzle pipe locking part. Next, one end of the second water supply pipe 96 is connected to the second water supply pipe connecting portion 91c from the first opening 42 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 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 intrusion 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 flush water from the toilet portion 2 is formed in the toilet apparatus 1, from the stop valve member 10 to the drain pipe 35.

[0041] In addition, in the toilet device 1 of this embodiment, as shown in Figure 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 prevention means 44 already attached to the first opening 42.

[0042] [Variations] A modified example of this embodiment will now be described with reference to Figure 10. Figure 10 is a rear view showing the first opening 142 of a toilet apparatus 101 according to a modified example of this embodiment. In a modification of this embodiment, the first opening 142 of the toilet apparatus 101 is machined to have a substantially perfect circle shape, as shown in Figure 10. In this modification, a water supply pipe connection portion 91a and a second water supply pipe connection portion 91c are installed in positions facing the first opening 142. By machining the shape of the water intrusion suppression means 44 shown in Figure 9 to match the shape of the first opening 142, it is possible to use a lid portion in this modification as well.

[0043] First opening 142 of this modification has a larger hole area formed in rear wall surface 141 than first opening 42 of the first embodiment, but because the accommodation section is provided with a reinforcing wall (not shown), deformation is suppressed unless excessive pressure is applied to rear wall surface 141. Furthermore, the substantially circular opening of first opening 142 of this modification can be formed more easily than the substantially elliptical hole of first opening 42 of the first embodiment.

[0044] The toilet device 1 of this embodiment described above provides the following effects.

[0045] The toilet apparatus 1 according to this embodiment is configured to include a flushing mechanism 9 and a toilet portion 2 having a housing portion 4 for housing the flushing mechanism 9 at the rear. More specifically, the storage section 4 of the toilet apparatus 1 is formed in a rear wall surface 41 thereof, and is configured to have a first opening 42 through which a first water supply pipe 92 is inserted. The flushing mechanism section of the toilet apparatus 1 is formed in its rear portion opposite the first opening 42, and is configured to have 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, it is not necessary to connect the water supply pipe and the connection part inside the cleaning mechanism part 9 as in the conventional cleaning mechanism part, and the height can be reduced. Therefore, according to this embodiment, it is possible to provide a toilet apparatus 1 in which the height of the flushing mechanism part 9 can be kept low. Furthermore, according to this embodiment, the height of the flushing mechanism 9 is kept low, which makes it possible to keep the height of the toilet apparatus 1 itself low. As a result, the entire toilet apparatus 1 can be made compact.

[0046] In addition, the cleaning mechanism unit 9 of this embodiment is configured to further have a second connection unit 91c formed at its rear 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 that extends 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 connector 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 the area 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, it is possible to minimize the size. Furthermore, according to this embodiment, the shape of the first opening 42 can be changed to a substantially perfect circle, which makes it easier to form the opening than a substantially elliptical opening.

[0047] Furthermore, the storage section 4 according to this embodiment is configured to have water intrusion prevention 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 infiltrating through the first opening 42 when the toilet apparatus 1 is flushed. Therefore, this embodiment can also be applied to toilets installed in shower rooms overseas, in hotels, etc. Furthermore, according to this embodiment, the water infiltration suppression means 44 also functions as a reinforcing material for the first opening 42, and the strength of the rear wall surface 41 can be maintained.

[0048] Additionally, the storage section 4 according to this embodiment is configured to further include a reinforcing wall 43 that extends 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 have 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, thereby suppressing deformation of the rear wall surface 41. As a result, the size of the opening (through hole) can be made larger than that of conventional toilet devices. This makes it possible to work with one's hand inserted into the first opening 42, facilitating the connection and locking work of the first water supply pipe 92 and the second water supply pipe 96.

[0049] [Second embodiment] Next, a toilet apparatus 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 of the toilet apparatus 201 according to the second embodiment.

[0050] A toilet portion 202 of a toilet apparatus 201 differs from the toilet apparatus 1 of the first embodiment in that it is adapted to a so-called wall drain toilet. More specifically, as shown in Figure 12, below the first opening 242 in the rear wall surface 241 of the toilet bowl part 202 (i.e., below the reinforcing wall 243), a second opening 245 is provided, through which a drain connection pipe 234 for wall piping is inserted. One end of the drain connection pipe 234 is connected to the downstream end 233b of the drain 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 bowl.

[0051] In the toilet apparatus 201 having the above configuration, the construction operation for connecting the first water supply pipe 292 and the second water supply pipe 296 is carried out in the same manner as in FIG. 6 of the first embodiment.

[0052] The installer inserts his / her 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. Thereafter, second water supply pipe locking portion 291d is used to lock the other end of second water supply pipe 296 to second water supply pipe connecting portion 291c. 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. Thereafter, 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. Thereafter, a lid part is fitted into this first opening 242, and then the drain connection pipe 234 of the toilet apparatus 201 is connected to a drain pipe provided behind the toilet apparatus 201.

[0053] The toilet apparatus 201 of this embodiment described above provides the following effects. The storage section 204 of the toilet apparatus 201 of this embodiment is configured to further have a second opening 245 formed in its rear wall surface 241 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 apparatus 201 can be applied to a wall-piped toilet in a building. Furthermore, in the toilet apparatus 201 of this embodiment, the reinforcing wall 243 ensures the strength of the rear wall surface 241, so the problem of deformation is unlikely to occur even in a toilet made of ceramic.

[0054] The present invention is not limited to the above-described embodiment, and includes modifications and improvements within the scope of achieving the object of the present invention. For example, although the toilet device of the present embodiment has been described above as being installed on the floor of a building in a pre-assembled state in a factory, it is also possible to assemble the toilet device at the installation site.
