Return to Figure 2. The drain pipe line 16 is connected to a drain pipe 44 installed in the building. The drain pipe 44 of this embodiment is embedded in the floor surface F of the toilet room. The drain pipe 16 includes a toilet drain channel 46 provided in the toilet main body 14. The drain pipe line 16 of this embodiment further includes a drain socket 48 that connects the toilet drain line 46 and the drain pipe 44, and a connection pipe 50 that connects the toilet drain line 46 and the drain socket 48.

The drain pipe 16 is provided with an ascending pipe 54 that constitutes a water seal storage section 52 . The rising pipe 54 rises toward the downstream side and extends rearward, and is provided in the toilet drainage channel 46 in this embodiment. A water seal 56 that blocks the flow of air within the drain pipe 16 is stored in the water seal storage section 52 .

The drain pipe 16 is provided with a descending pipe 58 that is located downstream of the rising pipe 54 and descends toward the downstream side. The descending pipe line 58 of this embodiment extends vertically downward toward the downstream side, and is provided in the drain socket 48 .

The drain pipe 16 is provided with a connecting pipe 60 that connects the ascending pipe 54 and the descending pipe 58. The connecting pipe line 60 of this embodiment extends linearly backward toward the downstream side, and is provided in the connecting pipe 50.

The drain pipe 16 includes a first pipe constituting member 62 that constitutes the drain pipe 16 . The first conduit component 62 of this embodiment is the connection pipe 50. The first pipe line forming member 62 includes a cylindrical first pipe connecting part 66 provided at the downstream end of the first pipe line forming member 62 . The first piping connection portion 66 is connected to the first piping member 64 . The first piping member 64 is arranged on the downstream side of the first pipe line forming member 62. The first piping member 64 of this embodiment is the drain socket 48. The first piping connection part 66 is connected to the first piping member 64 by being inserted inside the upstream end of the first piping member 64 (an upstream connection part 68 described later).

The first pipe connection 66 of the drain line 16 extends rearwardly (see also FIG. 3). As a result, by moving the toilet main body 14 in the front-rear direction X, the first piping connection portion 66 can be inserted into and removed from the first piping member 64 that has been placed in advance at the planned placement position of the toilet device 10. That is, by moving the toilet main body 14 in this manner, the first piping connection portion 66 can be connected to the first piping member 64 that has been arranged in advance. Therefore, in the work of connecting the first piping connection part 66 to the first piping member 64 arranged in advance, it is not necessary to lift the toilet main body 14 significantly from the floor surface F. As a result, good workability can be obtained.

The drain socket 48 includes an upstream connecting portion 68 to which the first pipe connecting portion 66 of the first pipe constituting member 62 is connected, and a downstream connecting portion 70 connected to the drain pipe 44 . The drain socket 48 of the present embodiment includes an upstream pipe 72 in which the upstream connection part 68 is provided, a downstream pipe 74 in which the downstream connection part 70 is provided, and an adjuster that connects the upstream pipe 72 and the downstream pipe 74. A tube 76 is provided.

In this embodiment, the upstream pipe 72 of the drain socket 48 is housed in the first cavity 28 , and the adjuster pipe 76 and the downstream pipe 74 of the drain socket 48 are housed in the second cavity 40 .

The adjuster tube 76 is provided with a straight tube portion 76a extending in the front-rear direction X. The adjuster pipe 76 is connected to the downstream pipe 74 by inserting a straight pipe portion 76a. The length of the drain socket 48 in the front-rear direction can be adjusted so as to change the relative position of the upstream connecting portion 68 and the downstream connecting portion 70 in the front-back direction. In this embodiment, this is achieved by cutting a portion of the straight pipe portion 76a of the adjuster tube 76 and adjusting the front-rear dimension of the straight pipe portion 76a. Thereby, by adjusting the relative positions of the upstream side connection part 68 and the downstream side connection part 70 according to the positions of the toilet main body 14 and the drain pipe 44, the range of compatible drain cores can be expanded. The "drain core" here refers to the distance from the wall part W rising from the floor surface F of the toilet room (hereinafter referred to as the toilet room wall part W) to the center line CL1 of the upstream end opening of the drain pipe 44.

The toilet device 10 includes a jet discharge section 80 that discharges water from a jet port 80a toward the downstream side of the drain pipe 16. The jet discharge section 80 discharges water backward from a jet port 80a that opens on the inner wall surface of the drain pipe 16.

See FIG. 6. The toilet device 10 includes a liquid supply path 90 that supplies liquid supplied from a liquid supply source to the toilet main body 14, an on-off valve 92 provided in the liquid supply path 90, and a liquid supply path upstream of the on-off valve 92. A check valve 94 provided in the passage 90 is provided. The toilet device 10 includes a branch path 96 branching from the liquid supply path 90 upstream of the on-off valve 92 , a pressure accumulator 98 connected to the liquid supply path 90 via the branch path 96 , and a pressure accumulator 98 connected to the liquid supply path 90 via the branch path 96 . A vacuum breaker 100 is provided in the liquid supply path 90 on the downstream side. Details of the vacuum breaker 100 will be described later.

The liquid supply source in this embodiment is the water supply. Water for cleaning the toilet bowl main body 14 (hereinafter referred to as cleaning water) is supplied to the liquid supply path 90 as a liquid. The on-off valve 92 is an electrically driven valve such as a solenoid valve or an electric valve, and can open and close the liquid supply path 90 under the control of a control unit (not shown).

The pressure accumulator 98 is an example of the liquid supply device 18 that supplies liquid to the toilet main body 14. The liquid supply device 18 of this embodiment can store the liquid supplied from the liquid supply path 90 and supply the stored liquid to the toilet main body 14 . The liquid supply device 18 stores cleaning water for toilet bowl cleaning as a liquid. The liquid supply device 18 includes an elongated main body 102 (see also FIG. 5), and the long axis of the main body 102 extends linearly. The main body 102 serves as a tank that stores the liquid supplied from the liquid supply path 90. The pressure accumulator 98 includes a partitioning member 108 such as a diaphragm that partitions the inside of the main body 102 into a main chamber 104 and a sub-chamber 106, and a biasing member such as a coil spring that urges the partitioning member 108 in a direction in which the volume of the main chamber 104 is reduced. A member 110 is provided.

Liquid can flow into the main chamber 104 of the pressure accumulator 98 from the liquid supply path 90 via the branch path 96 when the on-off valve 92 is in the closed state. The pressure accumulator 98 can gradually increase the amount of liquid stored in the main chamber 104 by moving the partitioning member 108 against the urging force of the urging member 110 due to the hydrostatic pressure of the liquid flowing into the main chamber 104. The pressure accumulating device 98 is capable of accumulating the pressure of the liquid in the main chamber 104 by the biasing force of the biasing member 110 . The pressure accumulator 98 moves the partitioning member 108 by the urging force of the urging member 110 when the on-off valve 92 is in the open state, thereby transferring the liquid under the accumulated pressure from the main chamber 104 through the liquid supply path 90. It can be supplied to the toilet main body 14. As a result, the liquid supplied from the liquid supply source joins the liquid pressure-accumulated by the pressure accumulator 98, and high-pressure liquid can be supplied to the toilet main body 14 through the liquid supply path 90.

Please refer to FIGS. 2, 5, and 7. In FIG. 5, only a part of the drain pipe line 16 above the liquid supply device 18 is shown by a chain double-dashed line. In a side view, at a position behind the ascending pipe 54 overlapping with the ascending pipe 54 in the longitudinal direction X and below the drain pipe 16 and overlapping with the drain pipe 16 in the vertical direction Z, A space 112 is provided. At least a portion of the main body 102 of the liquid supply device 18 is arranged in the first arrangement space 112 . "Side view" here is synonymous with viewing from the viewpoint of FIG. 2, that is, viewing from the left-right direction Y. When referring to a specific viewpoint in this way, it is assumed that the reference is made to the positional relationship of each component when viewed from that viewpoint, regardless of the external structure and internal structure. The first arrangement space 112 of this embodiment is provided inside the first cavity 28 of the toilet device 10.

The first arrangement space 112 is provided below the waterway top portion 314 (described later) of the drain pipe line 16. The first arrangement space 112 is provided between the ascending pipe line 54 and the descending pipe line 58 in a side view.

In the internal waterway 306 (described later) of the drain pipe 16, the deepest point on the inner upper surface of the water seal storage section 52 is designated as P1, the point immediately below the deepest point P1 is designated as P2, and the vertical direction of the point P1 and the point P2 is The central point is called P3. The main body 102 of the liquid supply device 18 is provided so that at least a portion thereof is located above the above-described center position P3 of the internal water channel 306 when viewed from the side. At least a portion of the main body 102 is provided above the lower end position P4 of the jet port 80a in side view. At least a portion of the main body 102 is provided above the lower end position P5 of the water seal storage section 52 of the drain pipe line 16 in a side view.

The main body 102 of the liquid supply device 18 is provided so as to protrude from the first arrangement space 112 on both sides in the left-right direction Y. It can also be said that the main body 102 is provided so as to protrude in the left-right direction Y from a location overlapping with the drain pipe 16 in the vertical direction Z when viewed from the rear. The main body 102 only needs to protrude to at least one side in the left-right direction Y.

The main body 102 of the liquid supply device 18 is arranged with its longitudinal direction facing the left-right direction Y. It is assumed that this condition is satisfied when the main body 102 is arranged such that the angle between the longitudinal direction axis and the left-right direction Y direction axis is 30° or less. As a result, compared to the case where the longitudinal direction of the main body 102 is aligned with the flow direction of the ascending pipe 54 (see FIG. 2) of the drain pipe 16, the vertical and front-to-back dimensions of the portion occupied by the main body 102 in the toilet device 10 are improved. can be made smaller. Accordingly, it is possible to reduce the size of the toilet device 10 in front and rear dimensions and in vertical dimensions.

The effects related to the above first point will be explained.

(A1) The first arrangement space 112 behind the ascending pipe 54 usually tends to become a dead space in which it is difficult to arrange other components of the toilet device 10. When the first arrangement space 112 is provided between the ascending pipe line 54 and the descending pipe line 58, the first arrangement space 112 is particularly likely to become a dead space. Since the liquid supply device 18 is disposed in the first arrangement space 112, which tends to become such a dead space, the toilet device 10 can be made smaller compared to a case where the liquid supply device 18 is disposed at another position.

The liquid supply device 18 is arranged in a third arrangement space 116 (see FIG. 5), which is a space that avoids the area below the toilet drainage channel 46 and is located behind the upper part of the toilet bowl part 12 of the toilet main body 14. Conceivable. According to the present embodiment, it is not necessary to arrange the liquid supply device 18 in such a third arrangement space 116, so in order to avoid interference with the liquid supply device 18, other components (for example, functions described later) can be installed. There is no need to shift the position of the component 152) up or down. Accordingly, the vertical dimensions of the entire toilet device 10 can be reduced in size.

The liquid supply device 18 may be placed below the bottom 52a (see FIG. 2) of the water seal storage section 52 of the drain pipe 16. According to this embodiment, since it is not necessary to arrange the liquid supply device 18 below the bottom 52a of the drain pipe 16, a part of the drain pipe 16 can be arranged there, and the drain pipe 16 is The degree of freedom regarding the placement position is improved.

Locations on both sides of the first arrangement space 112 in the left-right direction usually tend to become dead spaces in which it is difficult to arrange other components constituting the toilet device 10. The liquid supply device 18 of this embodiment is provided so as to protrude from the first arrangement space 112 in the left-right direction Y, and is arranged in a location that is likely to become such a dead space. Therefore, compared to the case where the liquid supply device 18 is disposed at another position, the toilet device 10 can be made smaller.

Next, other features related to the first point will be explained. See FIG. 2. A second arrangement space 118 is provided below the liquid supply device 18 in which a portion of the drain pipe 16 is arranged. The second arrangement space 118 is provided between the toilet main body 14 and the floor F below the liquid supply device 18. The second arrangement space 118 of the present embodiment is provided so as to widen toward the rear from the bottom 52a of the water seal storage section 52 of the drain pipe 16. The second arrangement space 118 of this embodiment is provided inside the second cavity 40 of the toilet device 10.

(A2) By providing the second arrangement space 118 below the liquid supply device 18, it is possible to realize a design in which the drain pipe 16 is arranged below the second arrangement space 118. As a result, the degree of freedom regarding the arrangement position of the drain pipe 16 is improved.

(A3) In this embodiment, a part of the drain socket 48 is arranged in the second arrangement space 118 as "a part of the drain pipe line 16". Therefore, the adjustment margin for the length of the drain socket 48 in the front-rear direction can be increased by the second arrangement space 118, and the range of compatible drain cores can be expanded.

Refer to FIGS. 2 and 7. The toilet device 10 includes a first partition part 34 that separates a first arrangement space 112 and a second arrangement space 118. The first partition wall portion 34 is provided in the toilet main body 14 as a part of the toilet main body 14 . A through hole 120 is formed in the first partition part 34 to communicate the first arrangement space 112 and the second arrangement space 118, and a part of the drain pipe 16 is inserted through the through hole 120. The "part of the drain pipe 16" here refers to the descending pipe 58 of the drain pipe 16 described above. The through hole 120 of this embodiment is a notch hole that opens rearward. The first partition wall portion 34 includes a first wall portion 34a that is connected to the rising pipe line 54 of the drain pipe line 16 and extends downward from the rising pipe line 54, and a second wall portion 34b that extends rearward from the lower end of the first wall portion 34a. and has.

The toilet device 10 is disposed below the liquid supply device 18 and includes a placement section 122 on which the liquid supply device 18 is placed. The mounting section 122 of this embodiment is configured by the first partition wall section 34 . The placing part 122 of this embodiment is provided in the toilet main body 14 as a part of the toilet main body 14. The liquid supply device 18 is fixed to the mounting portion 122 via a fixing member 126 using a screw (not shown) or the like while being placed on the mounting portion 122 . The liquid supply device 18 is arranged at a position spaced apart from the floor surface F, and is supported by the toilet main body 14 via the mounting section 122.

(A4) With this, the liquid supply device 18 can be arranged in the first arrangement space 112 simply by placing the liquid supply device 18 on the mounting portion 122. The liquid supply device 18 can be fixed in a state where the weight of the liquid supply device 18 is placed on the mounting portion 122. These factors combine to provide good workability when installing the liquid supply device 18.

See FIG. 3. The first arrangement space 112 described above is provided between the toilet drainage channel 46 and the first partition wall 34, that is, between the toilet drainage channel 46 and the mounting section 122. The toilet device 10 is configured such that the liquid supply device 18 can be taken in and out of the first arrangement space 112 in the horizontal direction (in the front-rear direction X in this embodiment). In this embodiment, when the drain socket 48 is removed from the drain pipe line 16, the liquid supply device 18 can be taken in and out in this way. Here, "can be taken in and taken out in the horizontal direction" does not mean that the direction in which the liquid supply device 18 is put in and taken out is along the horizontal direction, but rather that the horizontal component is larger than the vertical component. In this embodiment, an example will be described in which the direction in which the liquid supply device 18 is taken in and taken out is the front-rear direction X.

The liquid supply device 18 can be taken in and out of the mounting portion 122 by sliding. The liquid supply device 18 can be taken in and out through an inlet/outlet 124 provided in the first cavity 28 . In this embodiment, the entrance/exit port 124 opens the first arrangement space 112 rearward, and the liquid supply device 18 can be inserted into the first arrangement space 112 from the rear. The entrance/exit 124 is provided in the first cavity 28 between the first partition 34 and the partition member 32 of the toilet device 10 . The left-right dimension of the entrance/exit port 124 is larger than the longitudinal dimension of the main body 102 of the liquid supply device 18 . The left-right dimension here refers to the dimension along the left-right direction Y of the entrance/exit 124, and the longitudinal dimension refers to the dimension along the longitudinal direction of the main body 102.

(A5) Thereby, the liquid supply device 18 can be placed on the placement part 122 while the toilet main body 14 is placed on the floor F. Therefore, when placing the liquid supply device 18 on the placing part 122, there is no need to lift the toilet main body 14 or turn it upside down, and good workability can be obtained.

(A6) The first pipe connecting portion 66 of the first pipe constituting member 62 is arranged above the first arrangement space 112. The first piping connection portion 66 is connected to a first piping member 64 (in this embodiment, the drain socket 48) provided at the rear of the first arrangement space 112. Therefore, when the first piping member 64 is removed from the drain pipe line 16, the liquid supply device 18 can be taken in and out in the horizontal direction as described above. Thereby, when the liquid supply device 18 is arranged in the first arrangement space 112, it is not necessary to arrange the liquid supply device 18 in the first arrangement space 112 from below the toilet main body 14. As a result, good workability can be obtained.

(A7) The diameter of the portion where the first pipe constituting member 62 and the first piping member 64 are connected is easily increased compared to other portions of the first conduit constituting member 62 and the first piping member 64. The first pipe connecting portion 66 of the first pipe constituting member 62 located at such a location is arranged above the first arrangement space 112, as described above. Therefore, it is not necessary to provide the first pipe connection portion 66, which tends to have a large diameter, behind the first arrangement space 112. Accordingly, the first arrangement space 112 can be expanded in the front-rear direction X compared to the case where the first pipe connection part 66 of the drain pipe line 16 is arranged at the rear of the first arrangement space 112.

Next, the second point of improvement of the toilet device 10 will be explained. Please refer to FIGS. 2 to 4 and 7. The toilet device 10 of this embodiment includes a functional device 150 mounted on the toilet main body 14. The functional device 150 includes a functional component 152 and a casing 154 that houses the functional component 152. The functional component 152 refers to a device that performs a predetermined function associated with the toilet main body 14. The functional component 152 of this embodiment is a valve unit 153 that integrates an on-off valve 92, a check valve 94, and a vacuum breaker 100 in addition to a portion of the above-mentioned liquid supply path 90 and branch path 96. In FIG. 7, the liquid supply path 90 and the branch path 96 are schematically shown for convenience of explanation. In addition to this, the functional components 152 include, for example, a private parts cleaning device that cleans the private parts of a person sitting on a toilet seat, a drying device that blows drying air on the person sitting on the toilet to dry them, and a device that sucks odors in the toilet bowl portion 12. A deodorizing device that deodorizes the toilet bowl body 14, a foam supply device that supplies cleaning foam to the toilet main body 14, etc. may also be used.

The casing 154 includes a base plate 155 fixed to the toilet main body 14, and a case cover 156 assembled to the base plate so as to cover the base plate 155 from above. Functional component 152 is fixed to base plate 155.

The toilet device 10 includes the aforementioned first cavity 28 in which at least a portion of the functional component 152 is accommodated. The internal space of the first cavity 28 is partitioned by the partition wall member 32 into a third arrangement space 116 that accommodates the functional component 152 and a fourth arrangement space 117 that accommodates a portion of the drain pipe 16 (see FIG. 5). ). The fourth arrangement space 117 is provided below the third arrangement space 116 and includes the first arrangement space 112 described above. A valve unit 153 as a functional component 152 extends downward through a base plate 155 of a casing 154, and at least a portion thereof is arranged in the third arrangement space 116. Thereby, at least a portion of the functional component 152 is hidden by the first cavity 28, and the design can be improved.

The first cavity 28 is provided with an upper opening 160 that opens the third arrangement space 116 upward. The upper opening 160 opens into the upper surface 24 of the toilet main body 14. The functional component 152 of this embodiment is provided so as to vertically straddle the upper opening 160 in a side view.

The first cavity 28 is provided with a first rear opening 162 that opens the upper opening 160 rearward. The first rear opening 162 opens rearwardly the third arrangement space 116 in which the functional component 152 is arranged. In the first rear opening 162 of this embodiment, the fourth arrangement space 117 that accommodates a portion of the drain pipe 16 is also opened rearward. The first rear opening 162 of this embodiment is formed by the rear end of the outer peripheral wall 26 of the toilet device 10, the rear end of the first inner wall 36, and the rear end of the first partition wall 34 described above. configured.

The toilet device 10 includes the aforementioned second cavity 40 that accommodates a drain socket 48 . The second cavity 40 is provided with a lower opening 164 that opens the second arrangement space 118 downward, and a part of the drain socket 48 is arranged inside the lower opening 164. Ru. The lower opening 164 is defined by the lower end of the outer peripheral wall 26 of the toilet device 10.

The second cavity 40 is provided with a second rear opening 166 that opens the lower opening 164 rearward. The second rear opening 166 opens rearwardly the second arrangement space 118 in which the drain socket 48 is arranged. The second rear opening 166 of this embodiment is formed by the rear end of the first partition wall 34 described above in addition to the rear end of the outer peripheral wall 26 of the toilet device 10 . The second rear opening 166 can also be considered to be constituted by the rear end portions of the pair of outer wall portions 30 and the rear end portion of the first partition wall portion 34 .

The first cavity part 28 is not provided with a rear wall part that separates the internal space of the first cavity part 28 (in this embodiment, the third arrangement space 116 and the fourth arrangement space 117) and the external space in the front-rear direction X. . It can also be said that the first cavity 28 is provided so as to be exposed to the outside without covering a part of the functional component 152 and the drain socket 48 housed in the first cavity 28 when viewed from the rear. The second cavity part 40 is not provided with a rear wall part that separates the interior space (in this embodiment, the second arrangement space 118) of the second cavity part 40 from the exterior space in the front-rear direction X. It can also be said that the second cavity part 40 is provided so as to be exposed to the outside without covering a part of the drain socket 48 accommodated in the second cavity part 40. The external space here refers to the space provided outside the toilet device 10 behind the cavities 28 and 40 mentioned before the toilet main body 14 is fixed in the toilet room.

The toilet main body 14 is fixed to the floor F with the rear end 30a of the outer wall 30 of the toilet device 10 in contact with the toilet room wall W. To achieve this, this embodiment uses a fixing member 170, which will be described next.

See FIG. 7. In this embodiment, a pair of fixing members 170 are arranged with an interval left and right. The pair of fixing members 170 are arranged inside the pair of outer walls 30 of the toilet main body 14 . The fixing member 170 of this embodiment includes a floor fixing part 170a arranged on the floor surface F and a receiving part 170b rising from the floor fixing part 170a, and has an L-shape as a whole. The floor fixing part 170a is fixed to the floor surface F by a first screw member 172. A second screw member 174 that penetrates the outer wall portion 30 of the toilet main body 14 is screwed into the receiving portion 170b. The toilet main body 14 is fixed to the floor F via a fixing member 170 and screw members 172 and 174.

Return to Figure 2. In this embodiment, the rear end 30a of the outer wall 30 of the toilet device 10 is applied to the toilet room wall W via a cushioning material 176 (see also FIG. 1). This cushion material 176 is, for example, a sheet body using a resin foam such as expanded polyethylene foam. The cushioning material 176 is used to block foreign matter from entering from the external space between the toilet room wall W and the outer wall 30.

In this embodiment, the cushioning material 176 is provided in the entire range of the outer wall portion 30 in the vertical direction, excluding a cutout portion 178, which will be described later. The cushioning material 176 is arranged at least between the outer wall 30 of the toilet device 10 and the toilet room wall W. The cushioning material 176 is also arranged, for example, at the rear with respect to the internal spaces of the first cavity 28 and the second cavity 40. In addition to this, the cushioning material 176 is also arranged rearward with respect to the casing 154. However, the cushioning material 176 does not have to be arranged behind these.

The installation procedure of the toilet device 10 of this embodiment will be explained. First, the drain socket 48 is connected to the drain pipe 44 arranged in advance. Next, by moving the toilet bowl main body 14, the first pipe connection part 66, which is integrated with the toilet bowl main body 14, is connected to the drain socket 48.

Here, as shown in FIG. 3, the second cavity 40 of the toilet main body 14 of this embodiment is provided with a second rear opening 166 that opens the lower opening 164 rearward. Therefore, by moving the toilet bowl body 14 rearward, the drain socket 48 can be placed in the lower opening 164 through the second rear opening 166 of the toilet bowl body 14 . To perform this work, it is sufficient to simply move the toilet bowl main body 14 at a location close to the floor surface F. Therefore, it is not necessary to lift the toilet bowl main body 14 significantly from the floor surface F, and good workability can be obtained.

The effects related to the above second point will be explained.

(B1) The first cavity 28 is provided with an upper opening 160 that opens upward. Therefore, compared to the case where the functional component 152 is arranged on the upper surface portion 24 of the toilet main body 14, the vertical dimensions of the entire floor-standing toilet device 10 can be reduced.

If a rear wall section is provided in the first cavity section 28 behind the functional component 152, the position of the rear wall section is likely to vary greatly due to shrinkage due to drying in the molding process. This problem is particularly likely to occur when the first cavity 28 is provided in the ceramic toilet bowl body 14. Therefore, in order to absorb variations in the position of the rear wall of the first cavity 28, an extra space (hereinafter referred to as a variation absorption space) is provided between the rear wall of the first cavity 28 and the functional component 152. This results in an increase in the front-to-back dimensions of the toilet device 10 as a whole.

(B1) In this regard, according to the present embodiment, the first cavity 28 is provided with a first rear opening 162 that opens the upper opening 160 rearward. Therefore, it is not necessary to provide a variation absorbing space behind the functional component 152, and it is not necessary to provide a rear wall portion of the first cavity 28. Therefore, the front-to-back dimension of the floor-standing toilet device 10 can be reduced by the amount of the rear wall portion of the first cavity portion 28 and the variation absorbing space.

(B2) The toilet main body 14 is fixed with the outer wall 30 of the toilet device 10 in contact with the toilet room wall W. Therefore, it is possible to prevent dirt from entering from the external space between the outer wall 30 of the toilet device 10 and the toilet room wall W. Accordingly, it becomes difficult for dirt to accumulate between the toilet bowl device 10 and the toilet room wall W. As a result, it becomes easier to maintain the space between them in a clean state.

If the outer wall 30 of the toilet device 10 is not brought into contact with the toilet room wall W, dirt is likely to accumulate between them. Therefore, in order to maintain the space between them in a clean state, it is necessary to ensure a front-to-back dimension that is large enough to insert cleaning tools, and the front-to-back dimension from the toilet room wall W to the front end of the toilet device 10 must be secured. This will lead to larger size.

In this regard, according to the present embodiment, in order to maintain the space between the toilet bowl device 10 and the toilet room wall W in a clean state, it is not necessary to insert a cleaning tool between them, so that the dimension between them can be reduced. There is no need to secure it. Accordingly, in order to maintain the space between the toilet device 10 and the toilet room wall W in a clean state, the size of the toilet device 10 can be reduced in size.

In this way, when the outer wall 30 of the toilet device 10 is brought into contact with the toilet room wall W, the position of the toilet main body 14 in the front-rear direction with respect to the toilet room wall W cannot be changed significantly. For this reason, even if the position of the drain wick in the front-rear direction varies, it is not possible to compensate for the variation by changing the position of the toilet main body 14. In this regard, the toilet device 10 of this embodiment includes a drain socket 48. Therefore, even if the position of the toilet main body 14 cannot be changed in this way, by using the drain socket 48, it is possible to cope with variations in the position of the drain wick. This correspondence can be realized by adjusting the length of the drain socket 48 in the front-rear direction as described above. In addition to this, this correspondence can be realized by adjusting the insertion amount of the first pipe connection part 66 of the first pipe line forming member 62 with respect to the upstream connection part 68 of the drain socket 48.

The rear end 30a of the outer wall 30 of the toilet device 10 is placed against the toilet room wall W via a cushioning material 176. Therefore, even if the position of the outer wall 30 of the toilet device 10 with respect to the toilet room wall W varies, the variation can be absorbed by the cushioning material 176, making it possible to cope with the variation in the position of the toilet device 10. The variation in the position of the toilet device 10 here refers to a case where, for example, the rear end surface of the outer wall 30 of the toilet device 10 is not parallel to the toilet room wall W but is oblique.

Next, other features related to the second point will be explained. See FIG. 2. The rear end 30a of the outer wall 30 of the toilet device 10 is provided at a position that is aligned with the rear end 150a of the functional device 150 in the front-rear direction when viewed from the side. In this embodiment, the rear end portion 150a of the functional device 150 is constituted by a casing 154.

Thereby, when the rear end 30a of the outer wall 30 of the toilet device 10 is brought into contact with the toilet room wall W, it is possible to avoid a situation where only the functional device 150 comes into contact with the toilet room wall W first, and the functional device 150 can be protected. In order to obtain the same effect, the rear end 30a of the outer wall 30 may be provided at a position further back than the rear end 150a of the functional device 150 in side view.

Please refer to FIGS. 1 and 2. A notch 178 is formed in the rear end 30a of the outer wall 30 to communicate the internal space (second arrangement space 118) of the toilet device 10 with the external space. The cutout portion 178 is open rearward. The cutout portion 178 of this embodiment is formed at the rear end portion of each of the lower portions 514 (described later) of the left and right outer wall portions 30. The notch 178 of this embodiment is formed at the lower end of the outer wall 30 and is also open downward.

This notch 178 can be used as a space for inserting an object 180 arranged so as to straddle the internal space and external space of the toilet device 10 . In this embodiment, the object 180 to be inserted is an object fixed to the toilet room wall W, specifically, a baseboard. This embodiment has the advantage that when the toilet device 10 is placed against the toilet room wall W, the object 180 can be easily inserted into the inside of the notch 178 by moving the toilet device 10 backward. In addition to this, the object to be inserted 180 may be, for example, either a water supply pipe or a power supply cable.

Refer to FIGS. 2 and 7. The toilet device 10 of this embodiment includes a second partition wall 182 disposed between the drain pipe 16 and the functional component 152. The second partition wall portion 182 of this embodiment is constituted by a plate-shaped partition member 32 provided separately from the toilet main body 14 . At both ends of the partition wall member 32 in the left-right direction, fixed portions 32a formed by bending a part of the partition wall member 32 are provided. The fixed portion 32a is applied to a wall portion (in this embodiment, the first inner wall portion 36) constituting the first cavity portion 28 of the toilet bowl main body 14, and is secured to the toilet bowl main body 14 by being fastened together with a fastener such as a screw member. be integrated with.

The second partition 182 vertically separates a fourth arrangement space 117 in which the drain pipe 16 is arranged and a third arrangement space 116 in which the functional component 152 is arranged inside the first cavity 28 . The second partition wall portion 182 is provided with a first recessed portion 182a that is recessed upward at an intermediate portion in the left-right direction. A part of the drain pipe line 16, in this embodiment, the upstream pipe 72 of the drain socket 48 is arranged inside the first recess 182a. A second recess 182b recessed downward is formed on both left and right sides of the first recess 182a. A part of the functional component 152 is arranged inside the second recess 182b. The functional component 152 is arranged at a position overlapping the drain pipe 16 in the left-right direction Y in plan view.

The second partition wall 182 prevents an external force from being applied to the drain pipe 16 due to contact between the functional component 152 and the drain pipe 16, and prevents the drain pipe 16 from coming off the drain pipe 44. In addition to this, a situation in which unnecessary external force is applied to the functional component 152 can be avoided, and the functional component 152 can be protected.

Refer to FIGS. 3 and 5. A continuous opening 186 that continues from the upper opening 160 to the lower opening 164 is formed in the outer peripheral wall 26 of the toilet device 10 . The continuous opening 186 constitutes each of the first rear opening 162 and the second rear opening 166, and an opening that opens the through hole 120 rearward. "Continuous" here means that each of the left side edge 186a and the right side edge 186b of the continuous opening 186 is continuous from the upper opening 160 to the lower opening 164 by a single member. do. The "single member" here is the toilet main body 14 in this embodiment. In the continuous opening 186, a first rear opening 162 is provided above the first partition 34, and a second rear opening 166 is provided below the first partition 34.

This eliminates the need to provide a variation absorbing space behind the continuous opening 186 over the entire length of the toilet bowl body 14 in the vertical direction, and also eliminates the need to provide a rear wall portion of the toilet bowl body 14. Therefore, the front and back dimensions of the floor-standing toilet device 10 can be reduced over the entire length of the toilet bowl main body 14 in the vertical direction.

In order to obtain such an effect, the single member forming the left side edge 186a of the continuous opening 186 may be separate from the single member forming the right side edge 186b of the continuous opening 186. For example, the left side edge 186a may be configured by the toilet main body 14, and the right side edge 186b may be configured by a cover member 190 (described later).

The third point of improvement of the toilet device 10 will be explained. Please refer to FIGS. 2 to 4 and 8. The toilet main body 14 forms a rear space 220 behind the toilet bowl portion 12. The rear space 220 of this embodiment is the third arrangement space 116 formed inside the first cavity 28 described above. The rear space 220 is open upward when only the toilet main body 14 is fixed in the toilet room.

In this embodiment, the functional component 152 is arranged in the rear space 220. The functional component 152 arranged in the rear space 220 is an electrical component 204 equipped with electronic components. The electrical component 204 in this embodiment is a valve unit 153 equipped with an on-off valve 92 as an electronic component. In addition, the electrical component 204 may be, for example, a private parts cleaning device, a drying device, a deodorizing device, or the like. In any case, the specific example of the electrical component 204 is not particularly limited.

The upper end opening of the toilet bowl portion 12 constitutes an overflow edge 208. The overflow edge 208 here refers to a portion of the upper opening edge of the toilet bowl portion 12 that water that is about to overflow from inside the toilet bowl portion 12 can overcome, and is a specific area that water that is about to overflow cannot overcome. Locations are not included. The specific location is, for example, a location S1 (see FIG. 8) provided at a position on the upper opening edge of the toilet bowl portion 12 that overlaps the functional device 150 in the vertical direction. The rear end 208a of the overflow edge 208 in this embodiment is provided forward of the rear end 209 of the upper end opening of the toilet bowl portion 12. Here, "water overflows from inside the toilet bowl portion 12" assumes that, for example, the drain pipe 16 is clogged with objects such as filth.

Refer to FIGS. 3 and 9. The upper surface portion 24 includes a boundary portion 222 provided at the boundary between the upper surface portion 24 and the rear space 220 in plan view. The boundary portion 222 of this embodiment is the upper opening portion 160 of the first cavity portion 28 described above.

The upper surface portion 24 is provided with a high region 216 and a low region 218 having different heights so that the overflowing edge 208 of the toilet bowl portion 12 has a height difference. As a result, the overflow edge 208 is provided with a low location 208b below the height center Ch of the overflow edge 208. The high region 216 here refers to a location above the height center Ch of the overflow edge 208, and the low region 218 refers to a location below the height center Ch. The height center Ch here refers to the center position of the vertical range S2 of the overflow edge 208. In this embodiment, in plan view, the high region 216 is provided behind the boundary line Lb that passes through the overflow edge 208 and extends in the left-right direction Y, and the low region 218 is provided in front of the boundary line Lb. . It can also be said that the low region 218 is provided forward of the rear end 208a of the overflow edge 208. In this embodiment, by providing the inclined surface 214 on the upper surface portion 24, a high region 216 and a low region 218 are formed on the upper surface portion 24.

The low region 218 of this embodiment is provided so as not to be continuous with the boundary part 222 of the upper surface part 24 but to be continuous with the outer peripheral edge part 24a of the upper surface part 24 of the toilet main body 14 in plan view. Such a low-level region 218 can guide water overflowing over the low-level portion 208b of the overflow edge 208 to the outside of the toilet main body 14 through the low-level region 218 without passing through the rear space 220. FIG. 9 shows the guiding direction Pa of water overflowing from the overflow edge 208. When the low region 218 is formed by the slope 214 as in this embodiment, water passing over the low region 218 is guided to flow downward (upward in the drawing in FIG. 9) according to the slope of the slope 214.

The above-mentioned inclined surface 214 is provided on the upper surface portion 24 of the toilet main body 14. The inclined surface 214 is provided so that its height decreases continuously toward the front. The "height" here refers to the distance in the vertical direction from the horizontal plane passing through the floor surface F. The inclined surface 214 of this embodiment is provided in the range from the front end 24b to the rear end 24c of the upper surface 24 of the toilet main body 14. The inclined surface 214 is inclined so that the rear end 24c of the upper surface portion 24 is at the highest position and the front end 24b thereof is at the lowest position. The inclined surface 214 is uniformly inclined in the entire range in the front-rear direction X. In other words, the inclined surface 214 is provided so that the slope relative to the horizontal plane is the same throughout the entire range in the front-rear direction X.

The effects related to the above third point will be explained.

(C1) The low region 218 of the toilet main body 14 can guide water that overflows over the low point 208b of the overflow edge 208 to the outside of the toilet main body 14 without passing through the rear space 220. This makes it easier to prevent water overflowing from the toilet bowl portion 12 from flowing into the rear space 220. Water overflowing from the toilet bowl portion 12 can be guided to either the front or side space of the toilet main body 14 by the low region 218. Such a space is larger than the rear space 220, making it easier to place a part of the user's body and cleaning tools. Therefore, even if water overflows from the toilet bowl portion 12, good cleaning performance can be obtained by guiding the water to such an easy-to-clean location.

In addition, it becomes easier to avoid a situation where the electrical components 204 disposed in the rear space 220 get wet due to water overflowing from the toilet bowl portion 12. Furthermore, the electronic components mounted on the electrical component 204 can be protected.

The upper surface portion 24 of the toilet main body 14 is provided with an inclined surface 214 that forms a high region 216 and a low region 218. Therefore, compared to the case where a stepped portion forming the high-level region 216 and the low-level region 218 is provided, it is less noticeable in appearance. As a result, good design can be obtained.

The inclined surface 214 of the toilet bowl body 14 is uniformly inclined. Therefore, since no inflection point is provided on the inclined surface 214 of the toilet main body 14, the appearance becomes neat and a good design quality can be obtained. When transporting the toilet bowl base (described later) of the toilet bowl body 14 and the toilet bowl body 14 itself, the toilet bowl body 14 may be turned upside down. In this case, there is an advantage that the receiving surface of the pedestal that comes into contact with the upper surface portion 24 of the toilet main body 14 can be made flat, and the pedestal can be easily manufactured.

The inclined surface 214 of the toilet main body 14 is inclined so that its front end 24b is at the lowest position. Therefore, it is less noticeable in appearance than when the inclined surface 214 is provided so that the intermediate position in the front-rear direction X of the upper surface part 24 is at the lowest position, and a good design can be obtained.

Other features related to the third point will be explained. Please refer to FIG. The toilet seat 20 is provided with a plurality of legs 20a that protrude downward from the bottom surface of the toilet seat 20. The toilet seat 20 is supported by the inclined surface 214 of the toilet main body 14 by placing a plurality of legs 20a on the inclined surface 214 of the toilet main body 14. This inclined surface 214 is uniformly inclined. Therefore, even if the toilet seat 20 is displaced in the front-rear direction X, the contact state of the toilet seat 20 with the inclined surface 214 is unlikely to change. Therefore, compared to the case where the inclined surface 214 of the toilet main body 14 is not uniformly inclined, the toilet seat 20 can be stably supported by the inclined surface 214.

Next, details regarding the vacuum breaker 100 will be explained. See FIG. 6. The vacuum breaker 100 is provided in the liquid supply path 90 on the downstream side of the on-off valve 92. The vacuum breaker 100 is used to prevent backflow when negative pressure is generated in the liquid supply path 90 upstream of the vacuum breaker 100.

See FIGS. 10A and 10B. 10A and 10B are sectional views of the vacuum breaker 100 in FIG. 2, and are also sectional views taken along the line CC in FIG. 4. FIG. 10A shows a state in which the valve body 240 is in the outside air blocking position Pa1, and FIG. 10B shows a state in which the valve body 240 is in the outside air intake position Pa2. The vacuum breaker 100 includes a main body 230 in which a portion of the liquid supply path 90 is formed. The main body 230 includes an inflow path 232 through which cleaning water flows from the upstream side, an outflow path 234 through which the cleaning water that has flowed in from the inflow path 232 flows out, and a vent hole 236 that communicates the internal space of the outflow path 234 with the external space of the main body 230. Equipped with. The inflow path 232 is provided so as to extend in the vertical direction. The upstream portion of the outflow path 234 is provided to extend horizontally.

The main body 230 further includes a cylindrical part 230a that protrudes upward from the inner and lower surface of the outflow passage 234 and forms a part of the inflow passage 232 therein, and an inflow port of the inflow passage 232 that opens at the upper end of the cylindrical part 230a. 232a. A valve seat 238 that forms the peripheral edge of the inlet 232a is provided at the upper end of the cylindrical portion 230a.

Vacuum breaker 100 includes a valve body 240 housed in main body 230. The valve body 240 is supported so as to be movable up and down relative to the main body 230. The valve body 240 can be moved between an outside air blocking position Pa1 (see FIG. 10A) and an outside air intake position Pa2 (see FIG. 10B) by moving up and down with respect to the main body 230. When the wash water is supplied from the inflow path 232, the valve body 240 is pushed up by the wash water flowing in from the inflow path 232, and moves from the outside air intake position Pa2 to the outside air cutoff position Pa1. When cleaning water is not supplied from the inflow path 232, the valve body 240 moves downward due to its own weight, thereby moving from the outside air blocking position Pa1 to the outside air intake position Pa2.

As shown in FIG. 10A, when the valve body 240 is in the outside air blocking position Pa1, the valve body 240 opens the inlet 232a of the inflow path 232 by separating from the valve seat 238, and communicates the inflow path 232 and the outflow path 234. . At this time, the valve body 240 closes the vent hole 236 and blocks communication between the external space and the outflow path 234. As a result, cleansing water is supplied from the inflow path 232 to the outflow path 234 without outside air being taken into the outflow path 234 through the ventilation hole 236.

As shown in FIG. 10B, when the valve body 240 is in the outside air intake position Pa2, the valve body 240 closes the inlet 232a of the inflow path 232 by contacting the valve seat 238, and the inflow path 232 and the outflow path 234 are communicated with each other. cut off. At this time, the valve body 240 opens the ventilation hole 236 and communicates the external space with the outflow path 234. As a result, outside air is drawn into the outflow path 234 through the ventilation hole 236. Therefore, even when negative pressure is generated upstream of the inflow path 232 of the liquid supply path 90, by taking outside air into the outflow path 234 of the liquid supply path 90, the backflow can be prevented.

Here, as shown in FIG. 2, the height of the overflow edge 208 at which water starts to overflow from the toilet bowl portion 12 is Ha, and the height of the inlet 232a of the vacuum breaker 100 is Hb. At this time, as the difference ΔH1 between the height Hb of the inlet 232a of the vacuum breaker 100 and the height Ha of the overflow edge 208 increases, the water head pressure corresponding to the height of the difference increases. This makes it easier to prevent backflow within the liquid supply path 90. For this reason, in order to ensure the required backflow prevention performance, the inlet 232a of the vacuum breaker 100 is usually placed at a location a predetermined distance above the overflow edge 208. Required by national laws and regulations. Due to this, if the overflow edge 208 does not have a height difference, there is a limit to how low the upper end of the vacuum breaker 100 can be.

In the toilet device 10 of this embodiment, a high region 216 and a low region 218 are provided on the upper surface portion 24 so that the overflow edge 208 has a height difference ΔH2. Therefore, compared to the case where the entire overflow edge 208 is set to the same height as the maximum height Hc of the overflow edge 208, the height of the part of the overflow edge 208 where water starts to overflow from inside the toilet bowl portion 12 is lowered by ΔH2. can. Accordingly, the position of the inlet port 232a of the vacuum breaker 100 can be lowered by reducing the height by ΔH2. As a result, the position of the vacuum breaker 100 within the first cavity 28 can be lowered so that the upper end of the vacuum breaker 100 is lowered. As a result, the vertical dimensions of the toilet device 10 can be reduced.

Next, the positional relationship of the discharge hole 250A that discharges wash water into the toilet bowl portion 12 will be explained. See FIG. 3. As described above, the upper surface portion 24 of the toilet bowl body 14 is provided so as to become lower toward the front side, which is one side in the front-rear direction X, so that the overflow edge 208 of the toilet bowl portion 12 has a height difference. The toilet bowl portion 12 includes a rim portion 242 that constitutes the upper end portion of the toilet bowl portion 12 . The inner circumferential surface of the rim portion 242 constitutes a part of the range extending downward from the upper end opening of the toilet bowl portion 12 .

Refer to FIG. 11. The toilet device 10 includes discharge parts 252A and 252B that discharge wash water for cleaning the inside of the toilet bowl part 12 from discharge holes 250A and 250B. The discharge portions 252A and 252B of this embodiment are constituted by a part of the toilet main body 14. The discharge portions 252A and 252B in other embodiments may be provided separately from the toilet main body 14. The discharge parts 252A and 252B of this embodiment include a first discharge part 252A having a first discharge hole 250A, and a second discharge part 252B having a second discharge hole 250B. The first discharge hole 250A and the second discharge hole 250B open to the inner peripheral surface of the toilet bowl portion 12, specifically, to the inner peripheral surface of the rim portion 242. The first discharge hole 250A and the second discharge hole 250B are open to one side in the circumferential direction. Here, "one side in the circumferential direction" means counterclockwise in the paper of FIG. 11, and hereinafter also simply referred to as "counterclockwise."

The discharge portions 252A and 252B of this embodiment include a water passage 254 formed on the outer peripheral side of the toilet bowl portion 12. Each discharge part 252A, 252B discharges the wash water supplied from the liquid supply path 90 to the water passage 254 counterclockwise from the discharge hole 250A, 250B, and creates a swirling flow that swirls counterclockwise inside the toilet bowl part 12. Form. This swirling flow cleans the inner circumferential surface of the toilet bowl portion 12, and the filth within the toilet bowl portion 12 is discharged through the drain pipe 16.

Here, in plan view, a left-right center line Lc1 bisects the left-right dimension Dy of the upper end opening 12a of the toilet bowl portion 12, a front-rear center line Lc2 bisects the front-rear dimension Dx, and a left-right center line Lc1. Assume that the intersection point Pi of the front-rear center line Lc2 and the front-rear center line Lc2. The left-right center line Lc1 is a straight line extending along the front-rear direction X, and the front-rear center line Lc2 is a straight line extending along the left-right direction Y. The left-right dimension Dy refers to the maximum dimension in the left-right direction Y regarding the inner surface of the upper end opening 12a of the toilet bowl portion 12. The front-to-back dimension Dx refers to the maximum dimension in the front-to-back direction X regarding the inner surface of the upper end opening 12a of the toilet bowl portion 12. In a plan view, a first reference line Lc3 is obtained by rotating the left-right center line Lc1 by 45° to one side in the circumferential direction (counterclockwise in this embodiment) around the intersection Pi, and a first reference line Lc3 is obtained by rotating the left-right center line Lc1 by 45° in the circumferential direction around the intersection Pi. Assume that the second reference line Lc4 is rotated by 45 degrees to the other side of the direction. The "other side in the circumferential direction" here refers to the clockwise direction in the paper of FIG. 11, and is also simply referred to as "clockwise" hereinafter.

The toilet bowl portion 12 is divided into eight divided areas Da1 to Da8 by the left-right center line Lc1, the front-back center line Lc2, the first reference line Lc3, and the second reference line Lc4. The eight divided areas Da1 to Da8 are separate portions of the toilet bowl portion 12 that are divided by the lines Lc1 to Lc4 as boundaries in plan view. Among the eight divided regions Da1 to Da8, the divided region on the front side (one side in the front-back direction X in this embodiment) adjacent to each other in the counterclockwise direction with respect to the front-rear center line Lc2 is defined as a first divided region Da1. Among the eight divided areas Da1 to Da8, the remaining divided areas provided in order counterclockwise from the first divided area Da1 are referred to as second to eighth divided areas Da2 to Da8, respectively.

At this time, the first discharge hole 250A is provided in one of the plurality of divided regions Da2 to Da5 on the opposite side of the first divided region Da1 with respect to the second reference line Lc4. The first discharge hole 250A is provided in the third divided area Da3 as a divided area that satisfies this condition. In this embodiment, the second discharge hole 250B is provided in the sixth divided area Da6. Explain this advantage.

Consider a case where the upper surface portion 24 of the toilet bowl body 14 is provided so that the overflow edge 208 of the toilet bowl portion 12 has a height difference, and is lowered toward the front side (in this embodiment, one side in the front-rear direction). In this case, the rear portion of the rim portion 242 typically has a wider range in the vertical direction than the front portion.

(C2) Here, in this embodiment, the first ejection hole 250A is provided in the divided area Da3 on the opposite side of the first divided area Da1 with respect to the second reference line Lc4. Therefore, compared to providing the first discharge holes 250A in the first divided area Da1 and the eighth divided area Da8, it is easier to allow strong water to reach the rear portion of the rim portion 242. Accordingly, even when the vertical range to be cleaned is wide, such as the rear portion of the rim portion 242, the rear portion of the rim portion 242 can be easily cleaned with a strong force of cleaning water.

In order to obtain the effects described here, the first ejection holes 250A may be provided in the second divided area Da2, the fourth divided area Da4, and the fifth divided area Da5 in addition to the third divided area Da3. The position of the second discharge hole 250B is not particularly limited and may be omitted.

The fourth point of improvement of the toilet device 10 will be explained. Refer to FIGS. 12 and 13. The drain pipe 16 includes a second pipe constituting member 300 and a second piping member 302.

The second pipe connection portion 304 extends rearward. In this embodiment, the outer circumferential surface of the second pipe connection portion 304 has a circular shape and extends linearly. In order to form a circular shape in this way, the outer circumferential surface of the second piping connection part 304 only needs to be circular as a whole, and even if there is at least one of a convex part and a concave part in a part of the circumferential direction. good.

An internal water channel 306 is formed inside the drain pipe 16 and the drain pipe 44 (not shown), through which waste and water discharged from the toilet bowl section 12 pass. The second piping member 302 is provided on the downstream side of the internal water channel 306 than the second pipe line forming member 300 . The second piping member 302 is connected to the second piping connecting portion 304 by inserting the second piping connecting portion 304 of the second conduit forming member 300 inside the upstream portion thereof.

A portion of the waterway top 314 is formed by the upper end of the ascending surface 312 . A straight region 318 that extends linearly toward the downstream side within the drain pipe 16 is provided in the waterway top portion 314 of this embodiment.

The waterway top 314 is provided with an overflow edge 316 that defines the highest water level of the water seal 56 in a still water state. When water enters the drain pipe 16 over the overflow edge 316, the water overflows downstream from the overflow edge 316, thereby determining the highest water level of the water seal 56 remaining in the drain pipe 16.

The waterway top portion 314 is provided inside the second pipe connection portion 304 . A portion of the upward surface 312 (specifically, the downstream end) of the drain pipe line 16 and an overflow edge 316 are provided inside the second pipe connection part 304 .

The flow direction here refers to a direction in which water flows toward the downstream side within the drain pipe 16, and is a direction along the center line of the water channel forming surface 310 of the drain pipe 16. FIG. 13 is also a diagram showing a specific cross section of the second conduit component 300.

In the above-mentioned specific cross section, the second pipe line forming member 300 includes an outer peripheral wall part 320 that constitutes the outer peripheral surface of the second pipe connection part 304 and separates the outside from the inside, and a hollow part 322 provided below the water channel forming surface 310. and a partition part 324 that separates the inner space of the hollow part 322 and the water channel forming surface 310. In this embodiment, the hollow portion 322 and the partition wall portion 324 are provided at the downstream end of the toilet drainage channel 46.

The axis C1 of the water channel forming surface 310 is eccentric upward with respect to the axis C2 of the outer circumferential surface of the second pipe connection part 304 in the specific cross section. The waterway forming surface 310 of this embodiment is provided with a first similar surface 326 that is similar to a part of the outer circumferential surface of the second pipe connecting portion 304 in a specific cross section. "Similar shape" in this specification means that the two mentioned have similar shapes as a whole, even if there is a difference due to either a convex part or a concave part. good. The first similar surface 326 of the present embodiment is provided in a range that includes the inner upper surface of the waterway forming surface 310 and vertically straddles the axis C1 of the waterway forming surface 310.

The waterway forming surface 310 of this embodiment is provided with a first dissimilar surface 328 that is dissimilar to the outer circumferential surface of the second pipe connection portion 304 in a specific cross section. The first non-similar surface 328 of this embodiment is provided on the inner and lower surfaces of the water channel forming surface 310 and continues to both ends of the first similar surface 326 in the circumferential direction. The first dissimilar surface 328 constitutes the upper surface of the partition wall portion 324 in this embodiment. The first dissimilar surface 328 in this embodiment is a flat surface 330 parallel to the horizontal plane. A flat surface 330 parallel to the horizontal plane is provided on the inner and lower surfaces of the water channel forming surface 310 in a specific cross section passing through the water channel top 314. The flat surface 330 is provided at the lowest point of the waterway forming surface 310 in the specific cross section. The flat surface 330 is provided over the entire range of the aforementioned straight region 318 in the flow direction. "Parallel" in this specification is not limited to strictly geometrically parallel, but also includes substantially parallel.

The hollow portion 322 opens at the downstream end surface 304a of the second pipe connection portion 304, and has a bottomed shape that ends from the opening position toward the back side. The hollow portion 322 is provided with a second similar surface 332 that is similar to a part of the outer circumferential surface of the second pipe connection portion 304 and a second dissimilar surface 334 that is dissimilar to the outer circumferential surface. The second similar surface 332 of this embodiment is provided on the inner lower surface of the hollow portion 322, and the second dissimilar surface 334 is provided on the inner upper surface of the hollow portion 322. The second dissimilar surface 334 constitutes the lower surface of the partition wall 324 and is provided in a similar shape to the first dissimilar surface 328 that constitutes the upper surface of the partition wall section 324. The second dissimilar surface 334 of this embodiment is a flat surface parallel to the horizontal plane, similar to the first dissimilar surface 328.

The outer peripheral wall portion 26 has the same thickness in the circumferential range where the first similar surface 326 is provided, and extends around the axis C2. The outer peripheral wall portion 26 has the same thickness in the circumferential range where the second similar surface 332 is provided, and extends around the axis C2. The partition wall portion 324 is provided to have the same thickness as the outer peripheral wall portion 26 in a specific cross section.

The effects related to the above fourth point will be explained.

A water channel top portion 314 of the water seal storage portion 52 is provided inside the second pipe connecting portion 304 of the second pipe constituting member 300 . Therefore, compared to the case where the water channel top portion 314 is provided upstream of the second pipe connection portion 304 of the second pipe line forming member 300, the front and rear dimensions of the second pipe line forming member 300 can be made smaller, and as a result, The front and rear dimensions of the toilet device 10 can be made smaller.

The axis C1 of the waterway forming surface 310 is eccentric upward with respect to the axis C2 of the outer circumferential surface of the second pipe connection part 304 in a specific cross section passing through the waterway top part 314 of the water seal storage part 52. Therefore, the degree of freedom in designing the shape of the inner and lower surfaces of the water channel forming surface 310 can be increased compared to the case where the outer circumferential surface of the second pipe connection part 304 and the entire water channel forming surface 310 are made to have similar shapes. Along with this, while the outer circumferential surface of the second piping connection part 304 is shaped to be suitable for connection with the second piping member 302, the flow of water is different from that when the outer circumferential surface of the second piping connection part 304 is made to have a similar shape. The shape of the inner and lower surfaces of the water channel forming surface 310 can be designed to realize this.

In this embodiment, a flat surface 330 parallel to the horizontal plane is provided on the inner and lower surfaces of the water channel forming surface 310 in order to realize such different ways of water flow. This advantage will be explained in detail with reference to FIGS. 14A and 14B. FIG. 14A is a sectional view of a specific cross section of the second conduit forming member 300 of the first modification, viewed from the same viewpoint as FIG. 13. In the second pipe constituting member 300 of the first modification, a concave curved surface similar to the outer peripheral surface of the second pipe connection portion 304 is provided on the inner and lower surfaces of the waterway forming surface 310 in a specific cross section passing through the waterway top portion 314 .

As shown in FIGS. 14A and 14B, in the second conduit component 300 of the first modification and the second conduit component 300 of the first embodiment, a predetermined height is Consider the case where the water level rises by H0. In this case, according to the present embodiment, the flow rate of water attempting to exceed the water channel top 314 can be increased compared to the first modification. This can also be understood from the fact that the areas shown by hatching in FIG. 14B are larger than the areas shown by hatching in FIG. 14A. Therefore, according to this embodiment, when the water level of water that is about to exceed the water channel top 314 is low, it becomes easy to ensure a large drainage flow rate. The drainage flow rate here refers to the flow rate of water flowing through the drainage pipe line 16.

The outer circumferential surface of the second pipe connecting portion 304 of the second pipe constituting member 300 has a circular shape as the above-mentioned "shape suitable for connection with the second pipe member 302." As a result, the amount of elastic deformation of the sealing member 308 disposed between the second piping member 302 and the second pipe constituting member 300 is smaller than the case where the outer circumferential surface of the second piping connection portion 304 is polygonal. It becomes easier to stabilize regardless of the situation. Accordingly, the sealing performance of the sealing member 308 is stabilized regardless of the circumferential position. As a result, stable sealing performance can be easily ensured between the second piping member 302 and the second pipe line forming member 300.

Inside the second pipe connection part 304, a hollow part 322 is provided below the water channel forming surface 310 in a specific cross section. Thereby, compared to a case where the hollow part 322 inside the second pipe connection part 304 has a solid structure, the weight can be reduced by the presence of the hollow part 322. In addition, compared to such a case, waste material is suppressed in the area around the hollow part 322 of the second pipe connection part 304. Accordingly, the shape of the second pipe connection portion 304 can be stabilized by suppressing the effects of sink marks and the like caused by the waste material.

This hollow portion 322 is provided at the downstream end of the toilet drainage channel 46. As a result, during casting molding of the toilet base, which will be described later, by arranging a part of the rear mold 366 (see FIG. 16) at a location corresponding to the hollow part 322 of the toilet main body 14, this hollow part 322 can be easily formed. Can be molded.

Next, other features related to the fourth point will be explained. Refer to FIG. 12. A water drop portion 340 is provided at the waterway top portion 314 of the second pipe conduit member 300, and the water drop portion 340 is gradually lowered toward the downstream side in the internal waterway 306. Here, "gradual" means that there is a discontinuous height difference in the internal water channel 306 with the water drop portion 340 as a boundary. The water dropping part 340 of this embodiment is provided so as to form a discontinuous height difference between the inner and lower surfaces of the second piping member 302 and the water channel top part 314. The water dropping portion 340 can also be considered to be provided so as to form a stepped portion between them. The water dropping part 340 of this embodiment is constituted by the downstream end surface of the second pipe constituting member 300, and forms a corner part 342 between it and the water channel top part 314. The water dropping part 340 can drop water that has climbed over the water channel top 314 using gravity.

As a result, the water that has climbed over the waterway top 314 is dropped in the direction Pb using gravity on the downstream side of the water dropping part 340, thereby making it easier for water to flow downstream within the internal waterway 306 of the drain pipe 16. Become. Accordingly, the resistance of water flowing through the drain pipe 16 can be reduced compared to the case where the water drop portion 340 is not provided at the top portion 314 of the water channel. As a result, it becomes easier to secure the drainage flow rate.

Next, a method for casting the toilet bowl base will be explained. See FIG. 15. The toilet bowl base is a semi-finished product necessary to obtain the ceramic toilet bowl body 14, and is obtained by casting. The toilet base 350 of the toilet bowl body 14 includes an upper surface side portion 352 that includes at least a portion of the upper surface portion 24 of the toilet bowl body 14, and a toilet bowl side that includes most of the toilet bowl portion 12 and is lower than the upper surface side portion 352. portion 354. The upper surface side portion 352 and the toilet bowl side portion 354 have a shape in which the toilet main body 14 is divided into upper and lower parts. The toilet bowl side portion 354 is provided with the aforementioned toilet bowl drainage channel 46 and the second pipe connection portion 304.

The toilet bowl main body 14 is obtained by molding the toilet bowl bases of the upper surface side portion 352 and the toilet bowl side portion 354 by casting molding, joining them by adhesive or the like, and then performing a firing process. Hereinafter, a method of obtaining the toilet base of the toilet bowl side portion 354 by casting will be mainly explained.

See FIG. 16. A plurality of molds 360, 362, 364, 366 are used for casting. The plurality of molds 360, 362, 364, and 366 are made of a water-absorbing material such as plaster. The molds 360, 362, 364, and 366 of this embodiment include an upper mold 360 and a lower mold 362 arranged above and below the toilet base, and a front mold 364 and a rear mold 366 arranged before and after the toilet base. It will be done. The front mold 364 is composed of a pair of left and right split molds (not shown). The front mold 364 and the rear mold 366 form the external appearance of the toilet bowl side portion 354.

The rear mold 366 molds at least a portion of the rearward facing portion of the toilet bowl side portion 354. The rear mold 366 includes a molded recess 370 that molds the second pipe connection portion 304 of the toilet drainage channel 46 and a molded convex portion 372 that molds the hollow portion 322. The molding recess 370 is formed on the front surface of the rear mold 366 and is recessed rearward. The molded convex portion 372 projects forward from the bottom of the molded recess 370.

Cast molding includes the following steps: First, a step of forming a mold space 374 for molding a toilet base is performed by matching a plurality of molds 360, 362, 364, and 366. After this, a step of injecting uncured slurry 376 into the mold space 374 is performed. Through this process, the slurry 376 hardens along the surfaces of the molds 360, 362, 364, and 366, and the hardened portion of the slurry 376 forms the toilet base. After this, a step is performed to discharge uncured slurry 376 remaining inside the hardened portion of the slurry. After this, a process of removing each mold 360, 362, 364, and 366 from the toilet base is performed. In this step, the molding convex portion 372 of the rear mold 366 is extracted from the hollow portion 322 of the toilet bowl base 350 by moving the rear mold 366 relative to the toilet base 350 in the front-rear direction.

The molding recess 370 of the rear mold 366 forms a closing wall 378 in the toilet base 350 that closes off the internal space of the toilet drainage channel 46 from the downstream side. The blocking wall 378 of the toilet bowl base 350 is removed using fingers, a tool, or the like after the above-described demolding process and while the toilet base is still in a soft state before firing.

In this way, by using the rear mold 366 having the molded recesses 370 and the molded protrusions 372, it is possible to easily form the toilet main body 14 in which the hollow part 322 is provided inside the second pipe connection part 304 and below the water channel forming surface 310. can be obtained.

One end 504a of the cable member 504 is disposed in the internal space 506 of the toilet device 10 and is mechanically connected to the accessory device 500. The other end of the cable member 504 is placed outside the toilet device 10 and mechanically connected to the mating device 502.

The cable member 504 is disposed below the drain pipe 16 so as to cross in the left-right direction Y an overlapping position Pc where the drain pipe 16 overlaps with the drain pipe 16 in the vertical direction. The cable member 504 is arranged so as to cross in the left-right direction Y the above-described first arrangement space 112 provided at the overlapping position Pc. The cable member 504 of this embodiment is arranged in front of the descending pipe 58 of the drain pipe 16 so as to cross a position overlapping the descending pipe 58 in the front-rear direction X. The cable member 504 of this embodiment is arranged so as to cross in the left-right direction Y between the descending pipe 58 of the drain pipe 16 and the liquid supply device 18. The cable member 504 of this embodiment is arranged so as to be located above a part of the drain socket 48 arranged in the second arrangement space 118 described above. Part of the drain socket 48 here is the adjuster pipe 76 and the downstream piping 74.

The cable member 504 of this embodiment is arranged so as not to pass through the entire drainage pipe 16 at the rear. At least a portion of the orthogonal cross section of the cable member 504 is provided so as to be located forward from the rear end 26a of the outer peripheral wall portion 26 of the toilet device 10 in the entire region overlapping with the toilet main body 14 in the front-rear direction X. The orthogonal cross section here refers to a cross section perpendicular to the axial direction of the cable member 504. It can also be understood that the entire orthogonal cross section of the cable-like member 504 is provided so as not to be located further back than the rear end 26a of the outer circumferential wall portion 26 of the toilet device 10 in the entire region overlapping the toilet main body 14 in the front-rear direction X. I can do it.

The cable member 504 is connected to the accessory device 500 on one side in the left-right direction (the left side in this embodiment) with respect to the above-mentioned overlapping position Pc. The cable member 504 is placed on the placing portion 122 of the toilet device 10 and is arranged so as to cross the above-mentioned overlapping position Pc. The cable member 504 is pulled out from inside the outer peripheral wall 26 through a pull-out hole 516 (described later) on the other side in the left-right direction (the right side in this embodiment) with respect to the above-mentioned overlapping position Pc.

The cable member 504 is fixed to the mounting portion 122 using a fixture 508. The fixture 508 of this embodiment includes a clamp 508a that clamps the cable member 504, and a bolt 508b that removably fixes the clamp 508a to the toilet main body 14.

The cable member 504 is fixed to the toilet main body 14 using a fixture 508 on the other side in the left-right direction (the right side in this embodiment) with respect to the overlapping position Pc, similar to the position where it is pulled out from the pull-out hole 516. Ru. Thereby, even if the cord-like member 504 moves outside the toilet main body 14, a large movement of the cord-like member 504 inside the toilet main body 14 can be suppressed. In addition to this, the cable member 504 of this embodiment is fixed to the toilet main body 14 using a fixture 508 on one side in the left-right direction (left side in this embodiment) with respect to the overlapping position Pc.

From a similar point of view, the cable member 504 is fixed to the toilet main body 14 using a fixture 508 in the vicinity of the pull-out hole 516. The term "nearby" as used herein means, for example, a distance within 10 cm from the extraction hole 516. In addition to this, there is no other part hooked onto the cord member 504 between the position where the cord member 504 passes through the pull-out hole 516 and the position where the cord member 504 is fixed by the fixture 508.

See FIG. 19. The outer circumferential wall portion 26 includes a downward step portion 510 provided at a lower portion of the outer circumferential wall portion 26 . The lower part of the outer peripheral wall 26 here refers to the range from the lower end position of the outer peripheral wall 26 to a position Pd that is Lh x 0.5, where Lh is the total length of the outer peripheral wall 26 in the vertical direction Z. . The step portion 510 of this embodiment is provided at the lower end of the outer peripheral wall portion 26. The lower end of the outer peripheral wall 26 herein refers to the range from the lower end of the outer peripheral wall 26 to the position Pe which is Lh×0.2. The stepped portion 510 of this embodiment is provided in a range from the front end to the rear end of each of the pair of outer wall portions 30 that the outer peripheral wall portion 26 constitutes.

The outer peripheral wall portion 26 includes an upper portion 512 extending upward from the outer peripheral edge 510a of the stepped portion 510, and a lower portion 514 provided below the stepped portion 510. The step portion 510 is provided so that the outer dimensions of the upper portion 512 and the lower portion 514 of the outer peripheral wall portion 26 in the horizontal direction (in the present embodiment, the left-right direction Y) are different.

Refer to FIG. 21. The stepped portion 510 includes a lower surface 510b that is continuous with the outer peripheral edge 510a of the stepped portion 510, a recessed portion 510c that is recessed upward with respect to the lower surface 510b, and a wall portion 510d that separates the device internal space 506 from the external space. The wall portion 510d of this embodiment is provided at the bottom of the recess 510c.

The toilet device 10 includes a pull-out hole 516 formed in the outer peripheral wall 26. The cable member 504 is pulled out through the pull-out hole 516 as described above. The pull-out hole 516 is formed in the outer peripheral wall portion 26 in a range below the stepped portion 510 . This condition only needs to be satisfied by at least a portion of the extraction hole 516. The pull-out hole 516 of this embodiment is formed in the wall portion 510d of the stepped portion 510.

The extraction hole 516 is formed so as to avoid the outer surface of the upper portion 512. This means that the extraction hole 516 is not formed on the outer surface of the upper portion 512. The extraction hole 516 is formed so as to avoid the outer surface of the lower portion 514. This means that the extraction hole 516 is not formed on the outer surface of the lower portion 514.

Refer to FIGS. 19 and 21. In addition to the above-described first cavity 28 that accommodates the accessory device 500, the toilet main body 14 includes a hollow section 520 (see FIG. 4). The internal space of the hollow portion 520 is a place where a mold is not placed during cast molding. The internal space of the hollow portion 520 becomes a place where uncured slurry remains when the slurry is hardened to take a shape corresponding to the shape of the molded product during cast molding. The hollow part 520 includes a rear wall part 520a that covers the internal space of the hollow part 520 from the rear.

The toilet device 10 includes the aforementioned first inner wall section 36 that separates the inner space of the first cavity section 28 and the inner space of the hollow section 520, and an insertion hole 522 formed in the first inner wall section 36. The first cavity 28 includes an inner bottom surface 28a, an inner surface 28b rising from the inner bottom surface 28a, and an inner corner 28c where the inner bottom surface 28a and the inner surface 28b intersect. The insertion hole 522 of this embodiment is formed in the inner corner 28c.

The cable member 504 is pulled out from the extraction hole 516 via the first cavity 28, the insertion hole 522, and the hollow portion 520. The cable member 504 is pulled out from the pull-out hole 516 without passing through the second cavity 40 provided horizontally inside the stepped portion 510 .

Refer to FIGS. 19 and 22. The extraction hole 516 includes an opening 526 that opens in a direction intersecting the axial direction of a portion of the cable member 504 disposed within the extraction hole 516 . In this embodiment, the "intersecting direction" here means the horizontal direction, specifically, the rear direction. The opening 526 of this embodiment is continuous with the rear wall 520a of the hollow portion 520 and the insertion hole 522 in addition to the extraction hole 516, and these are also open toward the external space. An intermediate portion of the cable member 504 in the axial direction can be taken in and out in the direction Pf through the opening 526 between the extraction hole 516 and the external space. This direction Pf is a direction that intersects the axial direction of a portion of the cable member 504 disposed within the extraction hole 516.

The cable member 504 of this embodiment is inserted into the through hole 528 formed in the partition wall member 32 described above. The through hole 528 is also formed with an opening 530 that opens in a direction intersecting the axial direction of a portion of the cable member 504 disposed within the through hole 528 .

See FIG. 23. In this embodiment, in the following state, the cable member 504 can be taken in and out in the direction Pf through the opening 526 between the extraction hole 516 (not shown) and the external space. This state is a state in which the drain socket 48 is removed from the toilet drain channel 46 and before the toilet main body 14 is fixed in the toilet room. At this time, the cable member 504 is moved relative to the toilet main body 14 together with the accessory device 500 to which the cable member 504 is connected. In this embodiment, the accessory device 500 is moved relative to the toilet main body 14 together with the casing 154 (not shown) of the functional device 150 to which the accessory device 500 is fixed.

The effects related to the above fifth point will be explained.

The cable member 504 is arranged so as to cross in the left-right direction a position overlapping with the drain pipe 16 in the vertical direction. Therefore, even if the accessory device 500 and the companion device 502 are arranged on both sides of the left and right center position Px of the toilet main body 14, there is no need to secure a space for the cable member 504 behind the drain pipe 16. . Accordingly, the toilet main body 14 can be brought closer to the toilet room wall W, and the size of the toilet device 10 can be reduced. In addition, the drain socket 48 can be placed as close as possible to the toilet room wall W, and the range of compatible drain cores can be expanded accordingly.

The cable member 504 is disposed below the drain pipe 16 so as to cross a position overlapping the drain pipe 16 in the vertical direction. Therefore, there is no need for a space for arranging the cable member 504 above the drain pipe 16, and this space can be used as a space for arranging other accessories of the toilet device 10. In addition to this, a location below the drain pipe 16 that is likely to become a dead space can be utilized as a space for arranging the cable member 504. Therefore, it is possible to contribute to downsizing of the toilet device 10 through space saving.

The cable member 504 is arranged in front of the descending pipe 58 of the drain pipe 16 so as to cross a position overlapping the descending pipe 58 in the front-rear direction X. When the drain pipe 16 includes the descending pipe 58, the front of the descending pipe 58 is more likely to become a dead space. According to this embodiment, this location that is likely to become a dead space can be utilized as a space for arranging the cable member 504. Therefore, it is possible to contribute to further downsizing of the toilet device 10 through space saving.

(F) The extraction hole 516 is formed in the outer peripheral wall portion 26 in a range below from the downward step portion 510. A case will be considered in which the extraction hole 516 is formed in a part (for example, the upper part 512) that is smoothly continuous in the vertical direction without a step in the outer peripheral wall part 26. Compared to this case, the pull-out hole 516 is hidden by the upper portion 512 of the outer peripheral wall 26, making it difficult to visually recognize the pull-out hole 516 when the toilet device 10 is observed from the outside. This effect is particularly effectively obtained when the extraction hole 516 is formed in the stepped portion 510 of the outer peripheral wall portion 26. Accordingly, the appearance of the toilet device 10 becomes easier to maintain, and the design of the toilet device 10 can be improved.

The extraction hole 516 is formed in the lower part of the outer peripheral wall 26. Therefore, compared to the case where the extraction hole 516 is formed in the upper part of the outer peripheral wall portion 26, it is difficult for the user who is in a standing posture to visually recognize the extraction hole 516. Accordingly, the cable member 504 pulled out from the pull-out hole 516 can also be made difficult to see, resulting in a good design.

An accessory member having a larger outer diameter than the cable member 504 may be attached to a portion of the cable member 504 . This accessory member is, for example, a connector when the cable member 504 is a hose. The accessory member is an outlet when the cable member 504 is a cable. Depending on the size of the attached member, the attached member may get caught in the periphery of the pull-out hole 516. Therefore, depending on the size of the attached member, there may be cases where the cable member 504 cannot be inserted into the pull-out hole 516 from the end of the cable member 504.

In this respect, the middle portion of the cable member 504 of this embodiment can be taken in and out through the opening 526 of the pull-out hole 516. Therefore, the cable member 504 can be placed inside the extraction hole 516 regardless of the size of the attached member.

Let us consider a case where a stepped portion 510 is provided on the rear wall portion of the outer circumferential wall portion 26 and a pull-out hole 516 is formed in the stepped portion 510. In this case, a space is required between the outer peripheral wall 26 and the toilet room wall W to arrange the cable member 504 pulled out from the pull-out hole 516.

In this regard, in this embodiment, a stepped portion 510 is provided on the outer wall portion 30 of the outer peripheral wall portion 26, and a pull-out hole 516 is formed in the stepped portion 510. Therefore, it is not necessary to provide a rear wall portion on the outer peripheral wall portion 26. Accordingly, the range of drain cores that can be accommodated by the drain socket 48 can be expanded by the rear wall portion of the second cavity 40.

The extraction hole 516 is formed so as to avoid the outer surface of the upper portion 512. Therefore, when the toilet device 10 is observed from the outside, it becomes even more difficult to visually recognize the pull-out hole 516. Accordingly, the design of the toilet device 10 can be further improved.

The hollow part 520 of the toilet main body 14 is usually a part where a mold is not placed in casting molding, and tends to become a dead space. In this embodiment, the cable member 504 is pulled out from the pull-out hole 516 via the hollow portion 520 to the outside. Therefore, a location that is likely to become a dead space can be utilized as a space for arranging the cable member 504. Therefore, it is possible to contribute to downsizing of the toilet device 10 through space saving.

Other features related to the fifth point will be explained. Refer to FIG. 24. One of the front-rear direction X and the left-right direction Y is referred to as a specific direction. The specific direction in this embodiment is the left-right direction Y. The outer peripheral wall portion 26 includes the aforementioned outer wall portion 30 as an outer wall portion 532 facing outward in a specific direction (in the present embodiment, the left-right direction Y). The outer wall portion 532 separates the device internal space 506 from the external space in a specific direction.

A cross section cut along a specific direction (left-right direction Y in this embodiment) passing through the extraction hole 516 is referred to as a specific cut surface. FIG. 24 shows a specific cut plane. In this specific cut plane, a downward direction along a reference plane Ps forming an angle of 60° with respect to the horizontal plane Ph is referred to as a reference direction Pg. This reference plane Ps is a plane that extends downward as it goes inward in a specific direction. This reference direction Pg is assumed to be the user's line of sight direction. When this reference plane Ps touches the outer peripheral edge 510a of the stepped portion 510, the range inside the upper part 512 of the outer wall 532 and above the reference plane Ps is hidden by the upper part 512 of the outer wall 532. It means to be placed in a certain position.

At this time, the pull-out hole 516 is arranged at a position hidden by the upper portion 512 of the outer wall portion 532 when viewed from the reference direction Pg in this specific cut plane. It can also be said that the pull-out hole 516 is arranged at a position that is invisible when viewed from the reference direction Pg in the specific cut plane. This makes it even more difficult to visually recognize the pull-out hole 516 whenever the toilet device 10 is observed from the outside. Accordingly, the design of the toilet device 10 can be further improved.

This reference direction Pg is set based on the following idea. A lateral space 534 is formed between the toilet chamber wall W located on the side of the toilet main body 14 and the toilet main body 14. The distance from the left-right center position Px of the toilet main body 14 to the toilet room wall W is usually 435 mm at most. Let us consider a case in which an adult woman of a normal physique is cleaning while kneeling and bending forward, using this side space 534 as a work space. It is assumed that the height of this adult woman is 160 cm, and that her viewpoint is located at a distance of 40 cm (160 cm x 0.25) above the floor F. In this case, the position where the pull-out hole 516 formed at the lower end of the outer wall 532 is most easily visible is when the viewpoint Vp is on the toilet room wall W.

Assuming that there is a viewpoint Vp here, and if the reference plane passing through this viewpoint Vp and touching the outer peripheral edge 510a of the stepped portion 510 is Ps', then the angle θ0 of this reference plane Ps' with respect to the horizontal plane Ph is, for example, It becomes 56.5°. At this time, the range above the reference plane Ps' is located at a position hidden by the upper portion 512 of the outer wall portion 532 when viewed from the viewpoint Vp. In other words, if it is located inside the upper part 512 of the outer wall part 532 and above this reference plane Ps', the extraction hole 516 cannot be seen when cleaning by an adult of a normal physique. It will become.

Based on this idea, 60° is set as an angle that is more difficult to visually recognize than angle θ0, and the concept set from that angle becomes the above-mentioned reference direction Pg. If the pull-out hole 516 is arranged in a position where it cannot be visually recognized when viewed from the reference direction Pg, it can be considered that the pull-out hole 516 becomes invisible when an adult of a normal physique cleans. This cleaning location is assumed to be a lateral space 534 on the side of the toilet main body 14. In addition, the same effect can be obtained in the case of a space behind the toilet main body 14 that is narrower than the side space 534.

In addition, the second screw member 174 is arranged at a position hidden by the upper portion 512 of the outer wall portion 532 when viewed from the reference direction Pg in this specific cut plane. Similarly, the lower portion 514 of the outer wall portion 523 is arranged at a position hidden by the upper portion 512 of the outer wall portion 532 when viewed from the reference direction Pg in this specific cut plane.

The arrangement position of the partner device 502 changes depending on the installation location of the toilet device 10. FIG. 17 shows an example in which the counterpart device 502 is arranged on the other side (in this embodiment, on the right side) in the left-right direction Y with respect to the left-right center position Px of the toilet main body 14. FIG. 25 shows an example in which the partner device 502 is arranged on one side (left side in this embodiment) in the left-right direction Y with respect to the left-right center position Px of the toilet main body 14. A structure for dealing with this example will be described below.

Refer to FIGS. 19 and 26. The pull-out holes 516 are individually provided on both left and right sides with respect to the left-right center position Px of the toilet bowl main body 14. In this embodiment, the hollow portion 520 and the insertion hole 522 are also individually provided on both the left and right sides with respect to the left and right center position Px. When the counterpart device 502 is placed in the position shown in FIG. 17, the cable member 504 is placed so as to pass through the inner space of the hollow portion 520 on the right side and the insertion hole 522 in addition to the extraction hole 516 on the right side. When the counterpart device 502 is placed in the position shown in FIG. 25, the cable member 504 is placed so as to pass through the inner space of the left hollow portion 520 and the insertion hole 522 in addition to the left extraction hole 516. In either case, the accessory device 500 remains placed on one side in the left-right direction (the left side in this embodiment) with respect to the left-right center position Px. Thereby, the cable member 504 can be pulled out from the device internal space 506 regardless of the placement position of the partner device 502 in the left-right direction.

From the viewpoint of protecting the functional component 152 in the event of a fire, it is preferable that flames can be prevented from entering the third arrangement space 116 that accommodates the functional component 152. From this point of view, it is preferable to adopt the following configuration.

The partition member 32 is made of a noncombustible material that is hard enough to maintain a certain shape. The partition member 32 is made of, for example, metal such as iron, ceramics, or the like. Cushion material 176 may be constructed using a noncombustible material. As an example, the cushioning material 176 may be constructed using a nonflammable fiber material such as glass wool or rock wool. At least one of the pull-out hole 516, the insertion hole 522, and the through hole 528 may be covered with a nonflammable and flexible lid material. To achieve this, the lid material may be sandwiched, for example, between the accessory device 500 and the partition member 32 (see range S3 in FIG. 19). As an example of this lid material, the same fibrous material as the cushion material 176 may be used. Similar to the partition wall member 32, the portion of the accessory device 500 where the lid is clamped may be made of a noncombustible material that is hard enough to maintain a certain shape.

(Second Embodiment) Refer to FIGS. 27 to 29. The toilet device 10 of this embodiment is mainly related to the first point mentioned above. The liquid supply device 18 of this embodiment is a tank device 402 that includes a tank 400. The tank device 402 includes, in addition to a tank 400 that stores the liquid L to be supplied to the toilet main body 14, tank units 404A and 404B provided on a liquid path leading to the tank 400. The tank units 404A and 404B of this embodiment include a valve unit 404A as a first tank unit and a pump unit 404B as a second tank unit.

The valve unit 404A is provided as a liquid path leading to the tank 400 on a first liquid path 406A that supplies liquid from a liquid supply source to the tank 400. The liquid supply source in this embodiment is a water supply, as in the first embodiment, and supplies water as the liquid L. The valve unit 404A includes an on-off valve 408 and a first piping section 410A that constitutes the downstream end of the first liquid path. The on-off valve 408 is an electrically driven valve such as a solenoid valve, and can open and close the first liquid path 406A under the control of a control unit (not shown). When the on-off valve 408 is in the open state, the liquid L flows into the tank 400 through the first piping section 410A.

The pump unit 404B is provided on a second liquid path 406B that serves as a liquid path leading to the tank 400 and supplies the liquid L from the tank 400 to the toilet main body 14. The pump unit 404B includes a pump 412 and a second piping section 410B that constitutes the upstream end of the second liquid path 406B. The pump 412 can send out the liquid sucked from the tank 400 through the second liquid path 406B under the control of a control unit (not shown).

An example of the operation of the toilet device 10 related to the tank device 402 described above will be explained. The toilet device 10 includes a float switch (not shown) that detects whether the liquid level of the liquid L stored in the tank 400 exceeds a set liquid level. When the control unit determines that the liquid level in the tank 400 is below the set liquid level based on the detection result of the float switch, it switches the on-off valve 408 from the closed state to the open state. Thereby, the liquid L is supplied into the tank 400 through the first liquid path 406A.

When the control unit determines that the liquid level in the tank 400 exceeds the set liquid level based on the detection result of the float switch, it switches the on-off valve 408 from the open state to the closed state. As a result, the supply of the liquid L through the first liquid path 406A into the tank 400 is stopped. By going through the above series of operations, a set amount of liquid L is stored in the tank 400.

The control unit starts driving the pump 412 when a predetermined starting condition is met. This start condition is, for example, that a liquid supply start signal is input through operation of a switch (not shown) or the like. When the pump 412 is driven, the liquid L in the tank 400 is supplied through the second liquid path 406B. The control unit stops driving the pump 412 after a predetermined period of time has elapsed since the start of driving the pump 412 . Through the above series of operations, the set amount of liquid L is supplied from the tank 400.

The tank 400 will be explained in detail. The tank 400 is arranged at a position spaced apart from the toilet bowl portion 12 of the toilet main body 14 and the toilet drainage channel 46. The shape of the toilet bowl body 14 may vary due to shrinkage due to drying during the molding process. Therefore, if the tank 400 is placed in a position where it contacts the toilet bowl part 12 of the toilet main body 14 and the toilet drainage channel 46, if there are large variations in the shape of the toilet bowl part 12, etc., the tank 400 will be placed at the target position. It can be difficult to do so. In this regard, according to the present embodiment, since the tank 400 is arranged at a position spaced apart from these, the influence of variations in the shape of the toilet bowl portion 12 and the like can be eliminated.

The tank 400 is hidden from the outside by the outer circumferential wall part 26 of the toilet device 10, similar to the toilet bowl part 12 of the toilet main body 14 and the toilet drainage channel 46. Let us consider a case where at least one of the toilet bowl portion 12 of the toilet main body 14, the toilet drainage channel 46, and the tank 400 is covered with a dew-proofing material. Even in this case, the dew-proofing material can be hidden by the outer peripheral wall portion 26 of the toilet device 10, making it possible to achieve both good design and dew-proofing measures.

At least a portion of the tank 400 is arranged in the first arrangement space 112 described in the first embodiment. The tank 400 includes a first storage section 420 arranged in the first arrangement space 112. In addition, the tank 400 includes a second storage section 422 disposed on at least one side of the first storage section 420 in the left-right direction Y. In order to satisfy this condition, the second storage section 422 may be arranged at a position shifted in the front-rear direction X with respect to the first arrangement space 112. The second storage section 422 of this embodiment is arranged at a position overlapping the first arrangement space 112 in the front-rear direction X when viewed from the side. This condition is not essential. A storage chamber 424 that stores the liquid L is formed inside the tank 400. The storage chamber 424 is continuously formed inside the first storage section 420 and the second storage section 422 .

The second storage section 422 of this embodiment is provided so as to protrude upward from the upper surface of the first storage section 420, and is arranged at a position overlapping the drain pipe 16 in the left-right direction Y. The upper part of the second storage part 422 is arranged at a position overlapping in the left-right direction Y with a part of the drain pipe 16 provided above the first storage part 420. A portion of the second storage section 422 will be provided above the first storage section 420. The second storage portions 422 of this embodiment are individually arranged on both sides of the drain pipe line 16 in the left-right direction Y.

At least a portion of the first storage section 420 is provided above the aforementioned center position P3 of the internal waterway 306 of the drainage pipe line 16. The storage chamber 424 of the tank 400 is also provided to satisfy this condition. The liquid level Ls of the liquid L stored in the tank 400 is also set to satisfy this condition. These are provided so as to satisfy the same conditions in relation to the lower end position P4 and the lower end position P5 described above.

The tank 400 is provided so as to protrude from the first arrangement space 112 in the left-right direction Y. It can also be said that the tank 400 is provided so as to protrude in the left-right direction Y from a location overlapping with the drain pipe line 16 in the vertical direction Z, when viewed from the rear. The tank 400 of this embodiment is provided so as to protrude from the first arrangement space 112 on both sides in the left-right direction Y.

The effects of the toilet device 10 described above will be explained.

(E1) As described above, the tank 400 is arranged in the first arrangement space 112 behind the ascending pipe 54, which tends to become a dead space. The tank 400 of this embodiment is arranged in the first arrangement space 112 between the ascending pipe line 54 and the descending pipe line 58, which is particularly likely to become a dead space. Therefore, similar to the above-mentioned (A1), the size of the toilet device 10 can be reduced compared to the case where the tank 400 is arranged at another position. The "other position" here assumes the third arrangement space 116 described above.

(E2) The tank 400 is provided so as to protrude from the first arrangement space 112 in the left-right direction Y. Therefore, as described above, a part of the tank 400 is arranged at a location shifted in the left-right direction Y with respect to the first arrangement space 112, which tends to become a dead space. Therefore, the capacity of the tank 400 can be increased without increasing the size of the toilet device 10. In relation to such effects, the tank 400 only needs to protrude to at least one side of the first arrangement space 112.

(E3) The tank 400 includes a second storage section 422 in addition to the first storage section 420. Therefore, the capacity of the tank 400 can be increased by the second storage section 422.

(E4) The second storage portions 422 are individually arranged on both sides of the drain pipe 16 in the left-right direction Y. Therefore, the capacity of the tank 400 can be increased by the amount of the separate second storage section 422.

Other features regarding the toilet device 10 of this embodiment will be explained. Similar to the first embodiment, a second arrangement space 118 is provided below the tank 400 in which a part of the drain pipe 16 is arranged. This makes it possible to realize a design in which the drain pipe 16 is disposed below the tank 400, similar to the above-mentioned (A2). As a result, the degree of freedom regarding the arrangement position of the drain pipe 16 is improved.

Also in this embodiment, a part of the drain socket 48 is arranged in the second arrangement space 118 as "a part of the drain pipe 16". Therefore, as in (A3) above, the adjustment margin for the length of the drain socket 48 in the front-rear direction X can be increased by the second arrangement space 118, and the range of compatible drain cores can be expanded.

(E5) The tank 400 of this embodiment is placed on the placement part 122 of the toilet device 10, similar to the first embodiment. The tank 400 is mounted on the mounting portion 122 and is fixed to the toilet main body 14 using screws (not shown) or the like. The tank 400 is arranged at a distance from the floor F and is supported by the toilet main body 14. Thereby, as in (A4) above, good workability can be obtained when installing the tank 400.

The first pipe connecting portion 66 of the first pipe constituting member 62 is arranged above the first arrangement space 112. The first piping connection portion 66 is connected to a first piping member 64 (in this embodiment, the drain socket 48) provided at the rear of the first arrangement space 112. Therefore, similarly to the above-mentioned (A6), when the tank 400 is arranged in the first arrangement space 112, it is not necessary to arrange the liquid supply device 18 in the first arrangement space 112 from below the toilet main body 14. In addition, similar to the above-mentioned (A7), the first arrangement space 112 can be expanded in the front-rear direction X compared to the case where the first pipe connection part 66 of the drain pipe line 16 is arranged at the rear of the first arrangement space 112. Can be done.

(E6) Similar to the first embodiment, the toilet device 10 is configured such that the tank 400 can be taken in and out of the first arrangement space 112 in the horizontal direction. As a result, as in (A5) above, when placing the tank 400 on the placing part 122, there is no need to lift the toilet main body 14 or turn it upside down, resulting in good workability.

At least some of the tank units 404A and 404B are arranged above the tank 400. The tank 400 includes cylindrical pipe receiving parts 426A and 426B into which the pipe parts 410A and 410B of the tank units 404A and 404B are inserted. The pipe receiving parts 426A and 426B include a first pipe receiving part 426A into which the first pipe part 410A is inserted, and a second pipe receiving part 426B into which the second pipe part 410B is inserted. A sealing member 428 is arranged between the piping portions 410A, 410B and the piping receiving portions 426A, 426B. The sealing member 428 is an elastic body such as an O-ring, and seals between the piping portions 410A, 410B and the piping receiving portions 426A, 426B. Piping portions 410A and 410B are liquid-tightly connected to piping receiving portions 426A and 426B via a sealing member 428.

The pipe receiving parts 426A and 426B do not protrude toward the outside of the tank 400, but toward the storage chamber 424 side of the tank 400. It can also be said that the pipe receiving parts 426A, 426B protrude inwardly from the surrounding wall part 430 provided around the pipe receiving parts 426A, 426B of the tank 400, rather than projecting outwardly from the surrounding wall part 430.

(E7) This makes it difficult for the pipe receiving parts 426A, 426B to interfere with structures around the tank 400, compared to the case where the pipe receiving parts 426A, 426B protrude toward the outside of the tank 400. The "structure" here is the partition member 32 in this embodiment. Accordingly, the surrounding wall portion 430 of the tank 400 can be brought closer to the structure. Furthermore, when the tank 400 is placed near the structure, the capacity of the tank 400 can be increased.

Other modifications of each component will be explained.

The toilet main body 14 may be fixed to the wall W of the toilet room instead of the floor F of the toilet room. The toilet seat 20 may be attached to the toilet main body 14 via the casing 154, or may be attached directly to the toilet main body 14.

The drain line 16 may not include the drain socket 48. The drainage pipe line 16 does not need to be provided with the descending pipe line 58 on the downstream side of the rising pipe line 54. This assumes, for example, that the toilet drain channel 46 is connected to the drain pipe 44 embedded in the wall W of the toilet room.

The liquid supply device 18 only needs to be able to supply liquid to the toilet main body 14, and its specific example is not particularly limited. A specific example of the liquid is not limited to washing water, but may also be, for example, a liquid detergent. The use of the liquid stored in the liquid supply device 18 is not particularly limited. This liquid may be used, for example, in addition to a private parts cleaning device, a spray device that sprays the inside of the toilet bowl portion 12 for purposes such as sterilization.

The liquid supply destination of the liquid supply device 18 may be the toilet main body 14, and its specific example is not particularly limited. For example, liquid may be supplied to the drain pipe 16 and the like in addition to the toilet bowl portion 12 of the toilet main body 14.

The specific structure for making the length of the drainage socket 48 adjustable in the front-rear direction is not particularly limited. For example, a part of the drain socket 48 may be provided with a bellows structure that can be expanded and contracted in the front-rear direction.

In the first arrangement space 112, a circuit board or the like may be arranged as an alternative to the liquid supply device 18.

(Regarding the first point) The liquid supply device 18 may be provided so as not to protrude from the first arrangement space 112 in the left-right direction Y, or may be provided along the flow direction of the ascending pipe 54. good.

The second arrangement space 118 for arranging a part of the drain pipe 16 may not be provided below the liquid supply device 18. Unlike the embodiment, the toilet drain channel 46 of the drain pipe line 16 may be arranged in the second arrangement space 118.

The first piping member 64 may be, for example, the drain pipe 44, unlike the embodiment.

The toilet device 10 does not need to include the first partition wall part 34 and the second partition wall part 182 (partition wall member 32). The first partition wall portion 34 may be provided separately from the toilet main body 14. The second partition portion 182 may be provided in the toilet main body 14 as a part of the toilet main body 14.

The toilet main body 14 does not need to include the placing part 122. For example, the liquid supply device 18 may be fixed to the toilet main body 14 in a suspended and supported state.

The toilet device 10 does not need to be configured so that the liquid supply device 18 can be taken in and out of the first arrangement space 112 in the horizontal direction. This means that the liquid supply device 18 may be able to be taken in and out of the first arrangement space 112 from below.

In order to obtain the effect (A5), the direction in which the liquid supply device 18 is taken in and taken out may be the left-right direction Y, unlike the embodiment. When using the cover member 190, the direction in which the liquid supply device 18 is taken in and out may be either the left-right direction Y or the front-back direction X. In order to obtain the effect (A5), the toilet device 10 does not need to include the placing portion 122 as a part of the toilet main body 14. This means that the placing section 122 may be provided separately from the toilet main body 14.

The tank 400 only needs to include the first storage section 420 arranged in the first arrangement space 112, and does not need to include the second storage section 422. The tank 400 only needs to be at least partially arranged in the first arrangement space 112, and its specific arrangement position and shape are not particularly limited.

The pipe receiving parts 426A and 426B of the tank 400 may protrude toward the outside of the tank 400.

The structure disposed near the peripheral wall 430 of the tank 400 is not particularly limited. For example, the casing 154 of the functional device 150, the toilet main body 14, etc. may be used.

The tank units 404A and 404B may be fixed to the casing 154 of the functional device 150, or may be fixed to a different location from the casing 154. The "another location" here is, for example, the partition member 32. When the tank units 404A, 404B are fixed to a location different from the casing 154, the tank units 404A, 404B and the functional device 150 can be handled separately.

See FIG. 30. In the embodiment of FIG. 2, the descending line 58 of the drain line 16 is provided in the drain socket 48, and the first arrangement space 112 is provided between the toilet bowl drain line 46 and the drain socket 48. In addition to this, the first arrangement space 112 may be provided between the ascending pipe 54 and the descending pipe 58 of the toilet drainage channel 46. In this modification, the upstream portion of the descending pipe 58 of the drain line 16 is provided in the toilet drain channel 46, and the downstream portion of the descending pipe 58 is provided in the drain socket 48.

See FIG. 31. This modification is different from the embodiment shown in FIG. 2 in that the toilet main body 14 is wall-mounted. The wall-mounted toilet main body 14 is fixed to the toilet room wall W in a state where it is hung on the toilet room wall W. The toilet bowl main body 14 is arranged at a position spaced apart from the floor surface F. The toilet main body 14 of this modification is also provided with a jet discharge part 80.

The drain pipe 16 of this modification is also provided with a descending pipe 58 in addition to the rising pipe 54. The descending conduit 58 of this modification descends toward the downstream side and extends rearward. The drain pipe 16 of this example is provided with a rear pipe 78 that extends linearly rearward toward the downstream side of the descending pipe 58 and is connected to the drain pipe 44 . The descending pipe line 58 and the rear pipe line 78 are provided in the drain socket 48.

The drain socket 48 includes an upstream connecting portion 68 to which the toilet drain channel 46 is connected, and a downstream connecting portion 70 connected to the drain pipe 44, as in the first embodiment. The upstream connecting portion 68 of the drain socket 48 of this embodiment is directly connected to the downstream end of the toilet drain channel 46, unlike the first embodiment.

The first pipe constituting member 62 of this modification also includes a first pipe connecting portion 66 connected to the first pipe member 64. The first pipe constituting member 62 of this modification is the toilet main body 14, and the first piping member 64 is the drain socket 48. The first piping connection portion 66 of this modification also extends rearward.

Similar to the first embodiment, at least a portion of the main body 102 of the liquid supply device 18 is arranged in the first arrangement space 112. The first arrangement space 112 of this embodiment is provided between the ascending pipe line 54 and the descending pipe line 58 in a side view, similarly to the first embodiment. Unlike the first embodiment, a part of the drain pipe 16 is not arranged in the second arrangement space 118 below the liquid supply device 18 .

In this manner, when providing the first arrangement space 112 between the ascending pipe 54 and the descending pipe 58 of the drain pipe 16, the specific example of the descending pipe 58 is not particularly limited. The descending conduit 58 may not be provided behind the first arrangement space 112.

See FIG. 32. This modification is different from the embodiment shown in FIG. 27 in that the toilet main body 14 is wall-mounted. The drainage pipe line 16 of this modification also has the same configuration as the example of FIG. 31. The tank 400 of this modification is also arranged in the first arrangement space 112, similar to the embodiment of FIG. The tank 400 includes a first storage section 420 and a second storage section 422 (not shown), as in the modified example of FIG. 27 .

This example also includes the components explained in (E1) to (E7) above, and can obtain effects corresponding to those explanations.

Refer to FIGS. 33 and 34. This modification is different from the embodiments shown in FIGS. 28 and 29 in that it includes a plurality of tank devices 402. The plurality of tank devices 402 include a first tank device 402A and a second tank device 402B. The first tank device 402A includes a tank 400 (hereinafter referred to as the first tank 400A), as well as a valve unit 404A and a pump unit 404B, as in the second embodiment. The second tank device 402B includes a tank 400 (hereinafter referred to as a second tank 400B), a valve unit 404A, and a pump unit 404B as in the second embodiment. In FIG. 33, the pump unit 404B of the first tank device 402A and the valve unit 404A of the second tank device 402B are not shown. Both the first tank 400A and the second tank 400B are arranged within the first cavity 28 of the toilet device 10.

Liquids L for different purposes are stored in the first tank 400A and the second tank 400B. In the present embodiment, the first tank 400A stores, as the liquid L, washing water for toilet bowl washing, and the second tank 400B stores, as the liquid L, water for the private part washing device. By being supplied to the toilet bowl section 12 of the toilet bowl main body 14, the flushing water for toilet bowl cleaning can discharge the filth within the toilet bowl section 12 and clean the inside of the toilet bowl section 12. Water for the private parts cleaning device is supplied into the toilet bowl portion 12 of the toilet main body 14 via the private parts cleaning device.

The first tank 400A includes, in addition to the first storage section 420 arranged in the first arrangement space 112, a single second storage section 422 arranged on one side of the first storage section 420 in the left-right direction Y. Be prepared.

Unlike the second embodiment, the second tank 400B is not arranged in the first arrangement space 112, and is on the opposite side in the left-right direction Y from the second storage section 422 with respect to the first storage section 420 of the first tank 400A. will be placed in The upper part of the second tank 400B is arranged on the opposite side of the drain pipe 16 in the left-right direction Y from the second storage section 422 of the first tank 400A.

This example also includes the components described in (E1) to (E3) and (E5) to (E7) above, and can obtain effects corresponding to those descriptions. In addition, when liquids L for different purposes are stored in a plurality of tanks 400, one tank 400 can be arranged in the first arrangement space 112, thereby increasing its capacity.

Specific examples of the liquid L stored in the plurality of tanks 400 are not particularly limited. For example, one of the tanks 400 may store the liquid L for the spray device described above. As the liquid L, in addition to the washing water supplied from the waterworks, purified water obtained by purifying the washing water using a modifying material such as a filter medium may be used. When purified water is used, there is an advantage that limescale components adhering to the toilet bowl main body 14 can be removed by the purified water. Besides this, a liquid detergent may be used as the liquid L. This liquid detergent has a role of cleaning the inside of the toilet bowl part 12 by being supplied into the toilet bowl part 12 of the toilet main body 14, for example. The water for the private part washing device may be heated in advance and stored in the tank 400 as warm water. Thereby, it is possible to increase the flow rate of hot water injected from the private part cleaning device.

Unlike the embodiment, the pump unit 404B may supply the liquid L to the toilet main body 14 via a mechanical device such as a private area cleaning device or a spray device. In this case, such a mechanical device will be provided on the aforementioned second liquid path 406B.

(Regarding the second point) The first cavity section 28 and the second cavity section 40 may include a rear wall section that separates the interior space and the exterior space of each cavity section 28 and 40 in the front-rear direction. Also in this case, the first rear opening 162 may be provided in the first cavity 28 and the second rear opening 166 may be provided in the second cavity 40.

The rear end 30a of the outer wall 30 may be directly applied to the toilet room wall W without using the cushioning material 176. The cutout portion 178 may not be formed in the rear end portion 30a of the outer wall portion 30. The notch 178 may be formed at a location other than the lower end of the outer wall 30.

In order to obtain the above-mentioned effect (B1), the toilet device 10 may be fixed in a state where the rear end of the outer wall 30 of the toilet device 10 is not in contact with the toilet room wall W. This assumes that there is a gap between the toilet room wall W and the outer wall 30 of the toilet device 10.

In order to obtain the effect (B2) described above, the first cavity 28 of the toilet device 10 does not need to be provided with the upper opening 160 and the first rear opening 162.

In order to obtain the effects (B1) and (B2) described above, the arrangement position of the liquid supply device 18 is not particularly limited. This means that the liquid supply device 18 may be arranged in the third arrangement space 116 of the first cavity 28 and the second cavity 40. The liquid supply device 18 may be omitted.

Refer to FIGS. 35 and 36. The toilet device 10 of this modification includes a waterproof cover member 188 that covers and closes the continuous opening 186 of the toilet main body 14. This prevents water from entering the toilet body 14 through the continuous opening 186 of the toilet body 14. Accordingly, the electrical components 204 and the like arranged inside the toilet main body 14 can be protected. The cover member 188 of this modification is provided at a position aligned with the rear end 30a of the outer wall 30 of the toilet main body 14 in the front-rear direction X. In addition to this, the cover member 188 may be provided forward of the rear end portion 30a of the outer wall portion 30 of the toilet main body 14.

The toilet main body 14 of this example is also fixed with the outer wall 30 of the toilet device 10 in contact with the toilet room wall W. Thereby, the effect (B2) mentioned above can be obtained.

The first rear opening 162 and the second rear opening 166 do not have to be continuous with each other, unlike the embodiment.

In addition to this, when using the wall-mounted toilet main body 14, a cover member that covers and closes the internal space of the first cavity 28 from below may be used. This cover member is intended, for example, to cover and close the through hole 120 (see FIG. 3) of the toilet bowl main body 14.

See FIG. 37. A part of the outer wall portion 30 of this modification is constituted by a cover member 190 provided separately from the toilet main body 14. In this modification, a pair of cover members 190 constitute a part of each of the pair of outer wall portions 30 . The cover member 190 constitutes the outer wall portion 30 in a part of the range extending from the rear end portion 30a of the outer wall portion 30 in the front-rear direction X. The cover member 190 of this modification constitutes a part of the first cavity 28.

The cover member 190 is removably fixed to the toilet main body 14 via a fastener 192. A plurality of fixed portions 191 for fixing the cover member 190 are provided on the toilet main body 14 at intervals in the front-rear direction X. The fastener 192 of this modification is constituted by a pair of hook-and-loop fasteners attached to the toilet main body 14 and the cover member 190 at positions facing each other in the left-right direction Y. The fastener 192 fixes the cover member 190 to the toilet main body 14 so that the relative position of the cover member 190 in the front-rear direction X with respect to the toilet main body 14 can be adjusted. A specific example of the fastener 192 that satisfies this condition is not particularly limited. As a specific example, the fastener 192 may also be configured by a combination of a bolt and a long hole, a magnet, or the like.

Thereby, the rear end 30a of the outer wall 30 constituted by the cover member 190 can be brought into contact with the toilet room wall W while adjusting the position of the toilet bowl main body 14 in the front-rear direction X with respect to the toilet room wall W. By adjusting the position of the toilet main body 14 in the front-rear direction X in this manner, the position of the drain pipe 16 can also be adjusted, and variations in the position of the drain core in the front-rear direction X can be accommodated. That is, even when the outer wall 30 of the toilet device 10 is brought into contact with the toilet room wall W, variations in the position of the drain wick can be accommodated by changing the position of the toilet main body 14 in the front-rear direction X.

The cover member 190 may constitute the entire outer wall portion 30, unlike the modification shown in FIG. In this way, the cover member 190 only needs to constitute at least a portion of the outer wall portion 30.

An example has been described in which the cover member 190 covers the entire range of the outer wall portion 30 in the vertical direction Z. In addition to this, a part of the range in the vertical direction Z of the outer wall portion 30 may be configured by a cover member. In this case, the other range of the outer wall portion 30 in the vertical direction Z is constituted by the toilet main body 14. In this case, the portion of the cover member that constitutes the rear end 30a of the outer wall 30 and the portion of the toilet main body 14 that constitutes the rear end 30a of the outer wall 30 may be provided flush. In this case, the cover member may be fixed to either the toilet main body 14 or the casing 154 of the functional device 150 using the aforementioned fasteners 192.

(Regarding the third point) An example has been described in which the rear space 220 is the third arrangement space 116 inside the first cavity 28. When the toilet device 10 does not include the first cavity 28, the rear space 220 may be formed between the toilet room wall W and the toilet main body 14. The functional component 152 may not be arranged in the rear space 220.

The high region 216 and the low region 218 of the upper surface portion 24 of the toilet main body 14 may be formed by stepped portions instead of the inclined surface 214. This stepped portion is provided, for example, so that the height decreases stepwise toward the front.

In order to obtain the effect (C1) described above, the position of the low region 218 of the upper surface portion 24 of the toilet main body 14 is not particularly limited. For example, as shown in FIG. 38A, the low region 218 may be provided only in a part of the range in the front-rear direction X that overlaps the overflow edge 208 in the left-right direction Y in plan view. In addition, as shown in FIG. 38B, the low region 218 may be provided only in a part of the range in the left-right direction Y overlapping with the overflow edge 208 in the front-back direction X in plan view. In any case, the low region 218 only needs to be able to guide water that overcomes the low portion 208b of the overflow edge 208 to the outside of the toilet main body 14 without passing through the rear space 220. It is understood that the low region 218 may be capable of directing water that overcomes the low point 208b of the overflow edge 208 to either the front or the side of the toilet main body 14. In both the examples shown in FIGS. 38A and 38B, the high region 216 of the upper surface portion 24 of the toilet main body 14 is provided parallel to the horizontal plane.

The inclined surface 214 of the toilet bowl body 14 does not have to be uniformly inclined. This means that the slope of the inclined surface 214 may differ depending on the position in the front-back direction. For example, the slope forming the high region 216 and the slope forming the low region 218 may have different slopes.

Unlike the embodiment, the inclined surface 214 may be inclined so that the middle position of the upper surface portion 24 in the front-rear direction is the lowest position. Unlike the embodiment, the inclined surface 214 may be inclined so that the middle position of the upper surface portion 24 in the front-rear direction is the highest position. For example, the highest position of the inclined surface 214 may be located behind the toilet bowl portion 12 of the toilet main body 14, and the lowest position of the inclined surface 214 may be located at the front end portion 24b of the upper surface portion 24. The sloped surface 214 that satisfies this condition may be sloped uniformly.

The toilet seat 20 may be supported at a location other than the inclined surface 214 of the upper surface portion 24 of the toilet main body 14.

An example has been described in which "one side in the circumferential direction" which is the discharge direction of the first discharge hole 250A is counterclockwise, and the "other side in the circumferential direction" is clockwise. In addition, "one side in the circumferential direction" which is the discharge direction of the first discharge hole 250A may be clockwise, and the "other side in the circumferential direction" may be counterclockwise. In this case, the words "counterclockwise" and "clockwise" in the embodiment may be replaced with the words "clockwise" and "counterclockwise", respectively.

Regarding the height difference in the upper surface portion 24 of the toilet main body 14, when explaining an example in which the height becomes lower toward "one side in the front-rear direction," an example in which this "one side in the front-rear direction" is the front side has been described. In addition to this, "one side in the front-rear direction" may be the rear side. That is, the upper surface portion 24 of the toilet main body 14 may be provided so as to become lower toward the rear side (that is, one side in the front-rear direction) so that the overflow edge 208 has a height difference. In this case, the front portion of the rim portion 242 typically has a wider range in the vertical direction than the rear portion.

See FIG. 39. In this case, the first divided area Da1 is provided in a divided area on the rear side (that is, one side in the front-rear direction) adjacent to one side in the circumferential direction (counterclockwise in the drawing) with respect to the front-rear center line Lc2, The remaining divided areas are sequentially provided on one side in the circumferential direction from the first divided area Da1. In this case, in order to obtain the above-mentioned effect (C2), it is necessary to select one of the plurality of divided areas Da2 to Da5 on the opposite side of the first divided area Da1 with respect to the second reference line Lc4, as described above. It is preferable to provide a first discharge hole 250A. As a result, even if the front portion of the rim portion 242 has a wide range in the vertical direction to be cleaned, the front portion of the rim portion 242 can be easily cleaned with a strong force of cleaning water.

(Regarding the fourth point) Unlike the embodiment, the second conduit component 300 may be a connecting pipe 50 or the like. The second piping member 302 may be a drain pipe 44, a drain socket 48, etc., unlike the embodiment.

The axis C1 of the waterway forming surface 310 may be provided concentrically with the axis C2 of the second pipe connection portion 304 in a specific cross section passing through the waterway top portion 314.

In order to make the axis C1 of the waterway forming surface 310 eccentric upward with respect to the axis C2 of the second pipe connection part 304 in a specific cross section passing through the waterway top 314, a flat surface 330 is formed on the inner and lower surface of the waterway forming surface 310. It is not necessary to provide For example, an upwardly convex arcuate surface or the like may be provided on the inner and lower surfaces of the waterway forming surface 310.

In the case where the flat surface 330 is provided on the inner and lower surfaces of the waterway forming surface 310, an example has been described in which the flat surface 330 is constituted by the second conduit constituting member 300. The flat surface 330 may be formed by a separate member from the second pipe line forming member 300, for example, the second piping member 302.

The hollow portion 322 does not need to be provided below the water channel forming surface 310 inside the second pipe connection portion 304 . The outer peripheral surface of the second piping connection part 304 does not need to be circular, and may be polygonal, for example.

The overflow edge 316 may be formed by the apex of an arc-shaped region extending in an arc shape toward the downstream side within the drain pipe 16 .

The water drop portion 340 may not be provided at the top portion 314 of the water channel. For example, the waterway top portion 314 may be provided with a curved surface that becomes lower continuously toward the downstream side.

See FIG. 40. This modification example is different from the embodiment shown in FIG. 12 in the structure around the second pipe connecting portion 304 of the second pipe line forming member 300. In this modification, the second conduit component 300 is the toilet main body 14, as in the embodiment of FIG. In contrast, the second piping member 302 is a drain socket 48, unlike the embodiment of FIG.

The waterway top portion 314 of this modification is not provided with a linear region 318 (see FIG. 12) that extends linearly toward the downstream side. The downstream end of the water channel top 314 can also be considered to be constituted by the downstream end of the ascending surface 312.

The highest point 314a of the water channel top portion 314 is provided on the upstream side of the drain pipe line 16 rather than the downstream end surface 304a of the second pipe connection part 304. Similar to the embodiment of FIG. 12, the waterway top portion 314 of this modification is provided with a water drop portion 340 that becomes lower in stages toward the downstream side in the internal waterway 306. The water dropping part 340 of this modification is provided so as to form a discontinuous height difference between the inner lower surface of the second pipe connection part 304 and the water channel top part 314. The water dropping part 340 of this modification is provided inside the second pipe connection part 304 on the upstream side of the internal space of the descending pipe line 58 of the drain pipe line 16.

As a result, compared to the case where the highest point 314a of the water channel top 314 is arranged at a position aligned with the downstream end surface 304a of the second pipe connection section 304, the inner water channel 306 is located downstream of the highest point 314a of the water channel top 314. A wide space 380 can be secured. This space 380 is formed between the second piping member 302 and the waterway top 314 on the side horizontally opposite to the water seal 56 with respect to the waterway top 314 . Therefore, the water that has climbed over the waterway top 314 can easily flow toward the downstream side in the internal waterway 306, making it easier to ensure a large drainage flow rate. In particular, when the inner wall surface of the second piping member 302 is located at a location close to the downstream end surface 304a of the waterway top portion 314, the space 380 in the internal waterway 306 is made wider downstream than the highest point 314a of the waterway top portion 314. It's difficult. Even in such a case, the effects described here can be effectively obtained.

In addition, compared to the case where the downstream end surface 304a of the second pipe connection part 304 is aligned with the highest point 314a of the water channel top part 314, the second pipe connection part 304 is placed in the flow direction of the internal water channel 306. It can be done for a long time. Accordingly, the length of the second pipe connection part 304 necessary for ensuring sealing performance between the second pipe connection part 304 and the second pipe connection part 304 can be ensured.

Refer to FIG. 41. Also in this modification, as in the modification of FIG. 40, a water drop portion 340 is provided at the water channel top portion 314 of the second conduit component 300. This modification differs from the modification shown in FIG. 40 in the structure of the drain socket 48. In this modification, the drain socket 48 includes an oblique pipe section 382 provided in the descending pipe 58 and a first straight pipe section 384 provided in the descending pipe 58.

The diagonal conduit section 382 is provided at a position behind the first arrangement space 112 and overlapping with the first arrangement space 112 in the front-back direction. The diagonal pipe section 382 is provided so as to extend diagonally downward, more specifically, backward and downward as it goes downstream. The cross-sectional area of the inner peripheral surface of the diagonal pipe section 382 perpendicular to the tube axis direction is provided so as to gradually become smaller toward the downstream side. The first straight pipe section 384 is connected to the downstream side of the diagonal pipe section 382 and extends vertically downward toward the downstream side. A boundary portion 386 between the oblique pipe section 382 and the first straight pipe section 384 is provided at a position behind the first arrangement space 112 and overlapping with the first arrangement space 112 in the front-rear direction.

The upstream connecting portion 68 of the drain socket 48 includes a second straight pipe portion 388 that extends linearly and to which an elastic member 69 is attached. A diagonal pipe section 382 is connected to the downstream side of the second straight pipe section 388 . The acute angle θ1 formed by the central axis CL3 of the upstream end of the oblique pipe portion 382 with respect to the central axis CL2 of the second straight pipe portion 388 is set to be 30° or more.

Explain this advantage. Consider a case where an object, such as toilet paper, dropped from the water dripping part 314 of the waterway top part 314 lands on the inner and lower surface of the diagonal pipe part 382. In this case, since the diagonal pipe section 382 is provided so as to extend diagonally downward, objects on the inner lower surface thereof can easily flow downstream. Therefore, compared to the case where the second straight pipe part 388 of the drain socket 48 is provided over a wide range, objects dropped from the water drop part 314 are less likely to become clogged. At the same time, the first arrangement space 112 can be expanded in the front-rear direction compared to the case where the drain socket 48 does not have the diagonal conduit section 382. Therefore, it is possible to increase the size of the liquid supply device 18 arranged in the first arrangement space 112.

From the viewpoint of obtaining this effect, it is preferable that the following conditions are satisfied. In one cleaning operation, the maximum flow rate of water flowing down from the water dropping section 340 is referred to as Lmax (liter/sec). Here, one cleaning operation refers to an operation of supplying a predetermined amount of water from a water supply device (not shown) to clean the toilet bowl portion 12. The upstream end 382a of the inner lower surface of the diagonal pipe section 382 is provided at a position where it does not hit the water flow when the water flow of the maximum flow rate Lmax flows down from the water dropping section 314 in a parabolic shape.

In addition, from the viewpoint of obtaining the above-mentioned effects, it is preferable that the upstream end 382a of the diagonal pipe section 382 satisfies the following conditions. Specifically, the upstream end 382a of the diagonal pipe section 382 is preferably provided within a range of 20 mm or less in the horizontal direction on the downstream side of the water channel apex 314 with respect to the highest point 314a of the water channel apex 314; It is more preferable to set it within this range.

(Regarding the fifth point) The accessory device 500 may be any device attached to the toilet main body 14, and its specific example is not particularly limited. The accessory device 500 may be, for example, a functional component other than the valve unit 153, or may be the liquid supply device 18 described above.

The counterpart device 502 may be arranged in the internal space 506 of the toilet device 10, unlike the embodiment. In this case, the cable member 504 is disposed only in the device internal space 506 and is not pulled out from the device internal space 506. The companion device 502 disposed in the device internal space 506 may be, for example, an antifreeze heater that prevents water in the toilet drain channel 46 from freezing, a hot water heater that heats water to generate hot water, or the like. In addition to this, the partner device 502 arranged in the device internal space 506 may be a power source such as a motor used for a private parts cleaning device, a deodorizing device, etc., for example.

The specific example of the cable member 504 is not particularly limited. The cable member 504 may be arranged above the drain pipe 16 at a position overlapping the drain pipe 16 in the vertical direction. The drain line 16 does not need to include the descending line 58. This means that the cord-like member 504 does not have to be located in front of the descending conduit 58.

The extraction hole 516 may be formed in a stepped portion 510 provided in the rear wall portion of the outer peripheral wall portion 26. The extraction hole 516 may be partially formed on the outer surface of the upper portion 512, unlike the embodiment. The extraction hole 516 may be partially formed on the outer surface of the lower portion 514, unlike the embodiment. Unlike the embodiment, the pull-out hole 516 may be formed only on one side of the left and right sides with respect to the left-right center position Px of the toilet bowl main body 14. The extraction hole 516 does not need to include the opening 526.

The outer peripheral wall portion 26 of this embodiment constitutes a part of the toilet main body 14. Either the whole or a part of the outer peripheral wall 26 may be provided separately from the toilet main body 14.

The toilet main body 14 may not include the hollow portion 520. The cable member 504 may be pulled out from the pull-out hole 516 without passing through the hollow portion 520 of the toilet main body 14.

The outer circumferential wall portion 26 may include a rear wall portion that separates the internal space (device internal space 506) of the outer circumferential wall portion 26 from the external space in the front-rear direction X. When the above-mentioned specific direction is regarded as the front-rear direction X, the outer wall portion 532 facing outside in the above-mentioned specific direction corresponds to the rear wall portion of the outer peripheral wall portion 26. In this case, a stepped portion 510 may be formed in this outer wall portion 532 (rear wall portion), and a pull-out hole 516 may be provided in a range below the stepped portion 510. In this case, the extraction hole 516 may be arranged at a position hidden by the outer wall portion 532 when viewed from the reference direction Pg in the aforementioned specific cut plane.

See FIG. 42. The partner device 502 includes a first partner device 502A and a second partner device 502B. The first counterpart device 502A is a water stop valve, similar to the embodiment of FIG. The second partner device 502B is an outlet serving as an external power source that supplies commercial power. Similar to the embodiment of FIG. 17, each partner device 502A, 502B is arranged on the other side in the left-right direction Y (on the right side in this modification) with respect to the left-right center position Px of the toilet main body 14.

The cable member 504 includes a first cable member 504A that connects the accessory device 500 and the first partner device 502A, and a second rope member 504B that connects the accessory device 500 and the second partner device 502B. The first cable member 504A is a hose that supplies water, similar to the embodiment of FIG. The second cable member 504B is a cable that transmits power. The second cable-like member 504B supplies power to a power supply circuit (not shown) mounted on the accessory device 500 from an outlet serving as the second partner device 502B. The power supply circuit supplies power supplied from an external power supply to other attached devices.

The plurality of cable members 504 are pulled out from a common first extraction hole 516A via a common first insertion hole 522A. Therefore, the structure of the toilet device 10 can be simplified compared to the case where a plurality of cord-like members 504 are pulled out from individual pull-out holes 516.

The plurality of cable-like members 504 are arranged so as to cross in the left-right direction an overlapping position Pc that overlaps the drain pipe 16 in the up-down direction. Therefore, even if there are a plurality of cable members 504, there is no need to secure a space for arranging the cable members 504 behind the toilet main body 14. Accordingly, even when there are a plurality of cord-like members 504, the size of the toilet device 10 can be reduced in size, as described above.

In this way, the number of cable members 504 is not particularly limited. When there are a plurality of cable-like members 504, at least one cable-like member 504 may be arranged so as to cross a position overlapping the drain pipe 16 in the vertical direction. The plurality of cable members 504 may be pulled out from individual pull-out holes 516, unlike the modification shown in FIG. 42.

See FIG. 43. The pull-out hole 516 is formed below the stepped portion 510 in the outer peripheral wall portion 26 . Specifically, the extraction hole 516 is formed in the lower portion 514 of the outer peripheral wall portion 26. The pull-out hole 516 in this example is also formed in the range below the stepped portion 510 in the outer peripheral wall portion 26 . The pull-out hole 516 in this example is configured by the above-mentioned notch 178. The pull-out hole 516 of this embodiment includes an opening 526 that opens backward and downward, similar to the notch 178. The cable member 504 is pulled out from the extraction hole 516 via the first cavity 28 and the second cavity 40. This also makes it difficult to visually recognize the pull-out hole 516 when the toilet device 10 is observed from the outside, as it is hidden by the upper portion 512 of the outer peripheral wall 26, similar to the effect (F) described above.
