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

The drainage pipe 16 is provided with an ascending pipe 54 that constitutes a sealed water storage unit 52. The ascending pipe 54 rises toward the downstream side and extends rearward, and is provided in the toilet drainage channel 46 in the present embodiment. The sealed water storage section 52 stores the sealed water 56 that blocks the flow of air in the drainage pipe line 16.

The drainage pipe 16 is provided with a descending pipe 58 that descends toward the downstream side on the downstream side of the rising pipe 54. The descending pipeline 58 of the present embodiment extends vertically downward toward the downstream side, and is provided in the drainage socket 48.

The drainage pipe 16 is provided with a connecting pipe 60 that connects the rising pipe 54 and the descending pipe 58. The connecting pipe 60 of the present embodiment extends linearly backward toward the downstream side and is provided in the connecting pipe 50.

The drainage pipe line 16 includes a first pipe line constituent member 62 that constitutes the drainage pipe line 16. The first pipeline component 62 of the present embodiment is a connecting pipe 50. The first pipeline constituent member 62 includes a tubular first pipe connecting portion 66 provided at the downstream end of the first pipeline constituent member 62. The first pipe connecting portion 66 is connected to the first piping member 64. The first piping member 64 is arranged on the downstream side of the first pipeline constituent member 62. The first piping member 64 of this embodiment is a drainage socket 48. The first pipe connecting portion 66 is connected to the first piping member 64 by being inserted inside the upstream end portion (upstream side connecting portion 68 described later) of the first piping member 64.

The first pipe connection portion 66 of the drainage pipe line 16 extends backward (see also FIG. 3). As a result, by moving the toilet bowl body 14 in the front-rear direction X, the first piping connection portion 66 can be inserted and removed from the first piping member 64 which is arranged in advance at the position where the toilet bowl device 10 is scheduled to be arranged. That is, by moving the toilet bowl body 14 in this way, the first pipe connecting portion 66 can be connected to the first pipe member 64 which is arranged in advance. Therefore, in the work of connecting the first pipe connecting portion 66 to the first pipe member 64 arranged in advance, it is not necessary to lift the toilet bowl main body 14 significantly from the floor surface F. As a result, good workability can be obtained.

The drainage socket 48 includes an upstream side connection portion 68 to which the first pipe connection portion 66 of the first pipeline component 62 is connected, and a downstream side connection portion 70 connected to the drainage pipe 44. The drainage socket 48 of the present embodiment is an adjuster that connects an upstream pipe 72 provided with an upstream connecting portion 68, a downstream pipe 74 provided with a downstream connecting portion 70, and an upstream pipe 72 and a downstream pipe 74. It is provided with a pipe 76.

The upstream side connecting portion 68 is formed with an insertion port 68a into which the first pipe connecting portion 66 of the first pipeline component 62 is inserted. The insertion port 68a of the present embodiment is formed in an elastic member 69 provided in the upstream connection portion 68. The elastic member 69 is configured by using an elastic body.

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

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

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

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

The liquid supply source of this embodiment is a water supply. Water for washing the toilet bowl body 14 (hereinafter referred to as wash water) is supplied to the liquid supply passage 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 accumulator 98 is an example of a liquid supply device 18 that supplies a liquid to the toilet body 14. The liquid supply device 18 of the present embodiment stores the liquid supplied from the liquid supply passage 90, and can supply the liquid stored in itself to the toilet bowl main body 14. The liquid supply device 18 stores the washing water for washing the toilet bowl as a liquid. The liquid supply device 18 includes a long 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 for storing the liquid supplied from the liquid supply passage 90. The pressure accumulator 98 includes a partition member 108 such as a diaphragm that divides the inside of the main body 102 into a main chamber 104 and a sub chamber 106, and a coil spring or the like that urges the partition member 108 in a direction in which the volume of the main chamber 104 becomes smaller. A member 110 is provided.

When the on-off valve 92 is in the closed state, liquid can flow into the main chamber 104 of the accumulator 98 from the liquid supply passage 90 through the branch passage 96. The pressure accumulator 98 can gradually increase the amount of liquid stored in the main chamber 104 by moving the partition 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 accumulator 98 can accumulate the liquid in the main chamber 104 by the urging force of the urging member 110. When the on-off valve 92 is in the valve open state, the pressure accumulator 98 moves the partition member 108 by the urging force of the urging member 110 to move the liquid in the accumulated state from the main chamber 104 via the liquid supply path 90. It can be supplied to the toilet bowl body 14. As a result, the liquid accumulated by the accumulator 98 merges with the liquid supplied from the liquid supply source, and the high-pressure liquid can be supplied to the toilet bowl main body 14 through the liquid supply passage 90.

See FIGS. 2, 5, and 7. In FIG. 5, only a part of the drainage pipe line 16 above the liquid supply device 18 is shown by a chain double-dashed line. In the side view, the first arrangement is at a position that overlaps the ascending pipe 54 in the front-rear direction X behind the ascending pipe 54 and at a position that overlaps the drainage pipe 16 in the vertical direction Z below the drainage pipe 16. Space 112 is provided. At least a part of the main body 102 of the liquid supply device 18 is arranged in the first arrangement space 112. The "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 positional relationship of each component when viewed from that viewpoint is referred to regardless of the external structure and the internal structure. The first arrangement space 112 of the present embodiment is provided inside the first cavity 28 of the toilet bowl device 10.

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

In the internal waterway 306 (described later) of the drainage pipe 16, the deepest part of the inner upper surface of the sealed water storage part 52 is P1, the part directly below the deepest part P1 is P2, and the parts P1 and P2 are in the vertical direction. The central part of is called P3. The main body 102 of the liquid supply device 18 is provided so as to have at least a part above the above-mentioned central position P3 of the internal water channel 306 in a side view. At least a part of the main body 102 is provided so as to be above the lower end position P4 of the jet port 80a in a side view. At least a part of the main body 102 is provided so as to be above the lower end position P5 of the sealed water storage portion 52 of the drainage 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 be said that the main body 102 is provided so as to protrude in the left-right direction Y from a portion overlapping the drainage pipe line 16 in the up-down direction Z in the rear view. The main body 102 may protrude to at least one side in the left-right direction Y.

The main body 102 of the liquid supply device 18 is arranged so that its longitudinal direction is directed to the left-right direction Y. It is assumed that this condition is satisfied when the main body 102 is arranged so that the angle formed by the direction axis in the longitudinal direction is 30 ° or less with respect to the direction axis in the left-right direction Y. As a result, as compared with 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 drainage pipe 16, the vertical dimension and the front-rear dimension of the portion occupied by the main body 102 in the toilet bowl device 10 Can be miniaturized. Along with this, it is possible to reduce the size of the front-rear dimension and the vertical dimension of the toilet bowl device 10.

The effect of the above first device will be described.

(A1) The first arrangement space 112 behind the ascending pipeline 54 tends to be a dead space in which it is usually difficult to arrange other constituent devices constituting the toilet bowl device 10. When the first arrangement space 112 is provided between the ascending pipe 54 and the descending pipe 58, the first arrangement space 112 is particularly likely to become a dead space. Since the liquid supply device 18 is arranged in the first arrangement space 112 which tends to be such a dead space, the size of the toilet bowl device 10 can be reduced as compared with the case where the liquid supply device 18 is arranged at another position.

As the arrangement position of the liquid supply device 18, there is a third arrangement space 116 (see FIG. 5) which is a space avoiding the lower side of the toilet drainage channel 46 and is behind the upper part of the toilet bowl portion 12 of the toilet body 14. Conceivable. According to the present embodiment, since it is not necessary to arrange the liquid supply device 18 in such a third arrangement space 116, other constituent devices (for example, a function described later) are used to avoid interference with the liquid supply device 18. It is not necessary to shift the position of the component 152) up and down. Along with this, it is possible to reduce the vertical dimension of the entire toilet bowl device 10.

As the arrangement position of the liquid supply device 18, it is conceivable that the position is below the bottom portion 52a (see FIG. 2) of the sealed water storage portion 52 of the drainage pipe line 16. According to the present embodiment, since it is not necessary to dispose the liquid supply device 18 below the bottom 52a of the drainage pipe 16, a part of the drainage pipe 16 can be arranged there, and the drainage pipe 16 can be arranged. The degree of freedom regarding the placement position is improved.

The locations on both sides in the left-right direction with respect to the first arrangement space 112 usually tend to be dead spaces in which it is difficult to arrange other constituent devices constituting the toilet bowl device 10. The liquid supply device 18 of the present embodiment is provided so as to protrude in the left-right direction Y from the first arrangement space 112, and is arranged at a location where such a dead space is likely to occur. Therefore, the size of the toilet bowl device 10 can be reduced as compared with the case where the liquid supply device 18 is arranged at another position.

Next, other features related to the first device will be described. See FIG. Below the liquid supply device 18, a second arrangement space 118 for arranging a part of the drainage pipe line 16 is provided. The second arrangement space 118 is provided between the toilet bowl main body 14 and the floor surface F below the liquid supply device 18. The second arrangement space 118 of the present embodiment is provided so as to extend rearward from the bottom 52a of the sealed water storage portion 52 of the drainage pipe line 16. The second arrangement space 118 of the present embodiment is provided inside the second cavity portion 40 of the toilet bowl 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 drainage pipe line 16 is arranged below the second arrangement space 118. As a result, the degree of freedom regarding the arrangement position of the drainage pipe 16 is improved.

(A3) In the present embodiment, a part of the drainage socket 48 is arranged in the second arrangement space 118 as “a part of the drainage pipe line 16”. Therefore, the adjustment allowance for the length of the drainage socket 48 in the front-rear direction can be increased by the amount of the second arrangement space 118, and the range of the drainage core that can be handled can be expanded.

Refer to FIGS. 2 and 7. The toilet bowl device 10 includes a first partition wall portion 34 that separates the first arrangement space 112 and the second arrangement space 118. The first partition wall portion 34 is provided on the toilet bowl main body 14 as a part of the toilet bowl main body 14. A through hole 120 is formed in the first partition wall portion 34 through which the first arrangement space 112 and the second arrangement space 118 are passed, and a part of the drainage pipe line 16 is inserted through the through hole 120. The “part of the drainage pipe 16” here is the descending pipe 58 of the drainage pipe 16 described above. The through hole 120 of the present embodiment is a notch hole that opens backward. The first partition wall portion 34 is a first wall portion 34a that is connected to the rising pipe 54 of the drainage pipe 16 and extends downward from the rising pipe 54, and a second wall portion 34b extending backward from the lower end portion of the first wall portion 34a.

The toilet bowl device 10 is arranged below the liquid supply device 18 and includes a mounting portion 122 on which the liquid supply device 18 is placed. The mounting portion 122 of the present embodiment is composed of the first partition wall portion 34. The mounting portion 122 of the present embodiment is provided on the toilet bowl body 14 as a part of the toilet bowl body 14. The liquid supply device 18 is fixed to the mounting portion 122 via the fixing member 126 by using a screw or the like (not shown) in a state of being mounted 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 bowl main body 14 via the mounting portion 122.

(A4) As a result, the liquid supply device 18 can be arranged in the first arrangement space 112 simply by mounting the liquid supply device 18 on the placement unit 122. The liquid supply device 18 can be fixed in a state where the weight of the liquid supply device 18 is deposited in the mounting portion 122. Combined with these, good workability can be obtained when the liquid supply device 18 is installed.

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

The liquid supply device 18 can be taken in and out with sliding with respect to the mounting portion 122. The liquid supply device 18 can be taken in and out through the entrance / exit 124 provided in the first cavity 28. The entrance / exit 124 opens the first arrangement space 112 backward in the present embodiment, and the liquid supply device 18 can be inserted from behind the first arrangement space 112. The doorway 124 is provided in the first cavity 28 between the first partition 34 and the partition member 32 of the toilet bowl device 10. The left-right dimension of the entrance / exit 124 is larger than the longitudinal dimension of the main body 102 of the liquid supply device 18. The left-right dimension here means a dimension along the left-right direction Y of the entrance / exit 124, and the longitudinal dimension means a dimension along the longitudinal direction of the main body 102.

(A5) As a result, the liquid supply device 18 can be mounted on the mounting portion 122 while the toilet bowl main body 14 is placed on the floor surface F. Therefore, when the liquid supply device 18 is mounted on the mounting portion 122, it is not necessary to lift or turn the toilet bowl body 14 upside down, and good workability can be obtained.

Return to FIG. In the present embodiment, the rear end portion 30a of the outer wall portion 30 of the toilet bowl device 10 is applied to the toilet chamber wall portion W via the cushion material 176 (see also FIG. 1). The cushion material 176 is a sheet body using, for example, a resin foam such as foamed polyethylene foam. The cushion material 176 is used to block the invasion of foreign matter from the external space passing between the toilet room wall portion W and the outer wall portion 30.

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

The installation procedure of the toilet bowl device 10 of the present embodiment will be described. First, the drainage socket 48 is connected to the drainage pipe 44 arranged in advance. Next, by moving the toilet bowl body 14, the first pipe connection portion 66 integrated with the toilet bowl body 14 is connected to the drainage socket 48.

Here, as shown in FIG. 3, the second cavity 40 of the toilet body 14 of the present embodiment is provided with a second rear opening 166 that opens the lower opening 164 rearwardly. Therefore, by moving the toilet body 14 backward, the drainage socket 48 can be arranged in the lower opening 164 through the second rear opening 166 of the toilet body 14. In performing this work, it is only necessary to move the toilet bowl body 14 near the floor surface F. Therefore, it is not necessary to lift the toilet bowl body 14 significantly from the floor surface F, and good workability can be obtained.

The effect of the above second device will be described.

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

If a rear wall portion is provided in the first cavity portion 28 behind the functional component 152, the position of the rear wall portion is likely to vary greatly due to the influence of shrinkage due to drying in the molding process. In particular, this problem is likely to occur when the first cavity 28 is provided in the pottery body 14 made of earthenware. Therefore, in order to absorb the variation in the position of the rear wall portion of the first cavity portion 28, an extra space (hereinafter referred to as a variation absorption space) is provided between the rear wall portion of the first cavity portion 28 and the functional component 152. It is necessary to secure it, which leads to an increase in the front-rear dimension of the entire toilet bowl device 10.

(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 absorption space behind the functional component 152, and it is not necessary to provide a rear wall portion of the first cavity portion 28. Therefore, the front and rear dimensions of the floor-standing toilet bowl device 10 can be reduced by the amount of the rear wall portion of the first cavity portion 28 and the variation absorption space.

(B2) The toilet bowl main body 14 is fixed in a state where the outer wall portion 30 of the toilet bowl device 10 is in contact with the toilet room wall portion W. Therefore, it is possible to prevent the intrusion of dust passing between the outer wall portion 30 of the toilet bowl device 10 and the toilet room wall portion W from the external space. Along with this, it becomes difficult for dust to collect between the toilet bowl device 10 and the toilet room wall portion W. As a result, it becomes easier to keep them clean.

If the outer wall portion 30 of the toilet bowl device 10 is not applied to the toilet room wall portion W, dust is likely to collect between them. Therefore, in order to maintain a clean state between them, it is necessary to secure a front-rear dimension that allows the cleaning tool to be inserted, and the above-mentioned dimension from the toilet room wall W to the front end of the toilet bowl device 10. Invites upsizing.

In this regard, according to the present embodiment, in order to maintain a clean state between the toilet bowl device 10 and the toilet room wall portion W, it is not necessary to insert a cleaning tool between them, so that the dimensions between them are adjusted. There is no need to secure it. Along with this, in order to maintain a clean state between the toilet bowl device 10 and the toilet room wall portion W, the above-mentioned dimensions of the toilet bowl device 10 can be reduced.

As described above, when the outer wall portion 30 of the toilet bowl device 10 is applied to the toilet room wall portion W, the position of the toilet bowl main body 14 with respect to the toilet room wall portion W in the front-rear direction cannot be significantly changed. Therefore, even if the position of the drainage core in the front-rear direction varies, it is not possible to cope with the variation by changing the position of the toilet bowl main body 14. In this respect, the toilet device 10 of the present embodiment includes a drainage socket 48. Therefore, even when the position of the toilet bowl main body 14 cannot be changed in this way, the drainage socket 48 can be used to cope with the variation in the position of the drainage core. This correspondence can be realized by adjusting the length of the drainage 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 connecting portion 66 of the first pipeline constituent member 62 with respect to the upstream connecting portion 68 of the drainage socket 48.

The rear end portion 30a of the outer wall portion 30 of the toilet bowl device 10 is applied to the toilet chamber wall portion W via the cushion material 176. Therefore, even if the position of the outer wall portion 30 of the toilet bowl device 10 varies with respect to the toilet room wall portion W, the variation can be absorbed by the cushion material 176, and the variation in the position of the toilet bowl device 10 can be dealt with. The variation in the position of the toilet bowl device 10 here means, for example, a case where the rear end surface of the outer wall portion 30 of the toilet bowl device 10 is not parallel to the toilet room wall portion W but is oblique.

Next, other features related to the second device will be described. See FIG. The rear end portion 30a of the outer wall portion 30 of the toilet bowl device 10 is provided at a position aligned with the rear end portion 150a of the functional device 150 in the front-rear direction in a side view. In the present embodiment, the casing 154 constitutes the rear end portion 150a of the functional device 150.

As a result, when the rear end portion 30a of the outer wall portion 30 of the toilet bowl device 10 is brought into contact with the toilet room wall portion W, it is possible to avoid a situation in which only the functional device 150 comes into contact with the toilet room wall portion W first. Can be protected. In order to obtain the same effect, the rear end portion 30a of the outer wall portion 30 may be provided at a position rearward of the rear end portion 150a of the functional device 150 in the side view.

Refer to FIGS. 1 and 2. A notch 178 is formed in the rear end portion 30a of the outer side wall portion 30 so as to allow the internal space (second arrangement space 118) and the external space of the toilet device 10 to pass through. The notch 178 is open rearward. The cutout portion 178 of the present 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 portion 178 of the present embodiment is formed at the lower end portion of the outer wall portion 30, and is also open downward.

The cutout portion 178 can be used as a space for inserting the inserted object 180 arranged so as to straddle the internal space and the external space of the toilet bowl device 10. In the present embodiment, the insertion object 180 here is an object fixed to the wall portion W of the toilet room, specifically a skirting board. In the present embodiment, when the toilet device 10 is applied to the wall portion W of the toilet room, by moving the toilet device 10 backward, there is an advantage that the inserted object 180 can be easily inserted inside the notch 178. In addition to this, the insertion object 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 the present embodiment includes a second partition wall portion 182 arranged between the drainage pipe line 16 and the functional component 152. The second partition wall portion 182 of the present embodiment is composed of a plate-shaped partition wall member 32 provided separately from the toilet bowl main body 14. Fixed portions 32a formed by bending a part of the partition wall member 32 are provided at both ends of the partition wall member 32 in the left-right direction.

The second partition wall portion 182 vertically separates the fourth arrangement space 117 in which the drainage pipe line 16 is arranged and the third arrangement space 116 in which the functional component 152 is arranged inside the first cavity portion 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. Inside the first recess 182a, a part of the drainage pipe line 16, in the present embodiment, the upstream side pipe 72 of the drainage socket 48 is arranged. A second recess 182b that is recessed downward is formed on both the 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 drainage pipe line 16 in the left-right direction Y in a plan view.

By the second partition wall portion 182, it is possible to avoid a situation in which an external force is applied to the drainage pipe line 16 due to the contact between the functional component 152 and the drainage pipe line 16, and it is possible to avoid a situation in which the drainage pipe line 16 comes off from the drainage pipe 44. At the same time, it is possible to avoid a situation in which an extra external force is applied to the functional component 152, and to protect the functional component 152.

See FIGS. 3 and 5. The outer peripheral wall portion 26 of the toilet bowl device 10 is formed with a continuous opening 186 that is continuous from the upper opening 160 to the lower opening 164. The continuous opening 186 constitutes each of the first rear opening 162 and the second rear opening 166, and an opening for opening the through hole 120 backward. "Continuous" here means that each of the left edge portion 186a and the right edge portion 186b of the continuous opening 186 is continuous with a single member from the upper opening 160 to the lower opening 164. do. The "singular member" here is the toilet bowl main body 14 in the present embodiment. The continuous opening 186 is provided with a first rear opening 162 above the first partition 34 and a second rear opening 166 below the first partition 34.

As a result, it is not necessary to provide a variation absorption space behind the continuous opening 186 over the entire length of the toilet bowl body 14 in the vertical direction, and it is not necessary to provide a rear wall portion of the toilet bowl body 14. Therefore, it is possible to reduce the size of the front-rear dimension of the floor-standing toilet device 10 within the range of the entire length of the toilet body 14 in the vertical direction.

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

The third device of the toilet bowl device 10 will be described. See FIGS. 2, 4, and 8. The toilet bowl body 14 forms a rear space 220 behind the toilet bowl portion 12. The rear space 220 of the present 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 body 14 is fixed to the toilet room.

In the present 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 an electronic component. 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 to this, the electrical component 204 may be, for example, a local cleaning device, a drying device, a deodorizing device, or the like. In any case, specific examples of the electrical component 204 are 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 end opening edge of the toilet bowl portion 12 where the water to overflow from the inside of the toilet bowl portion 12 can be overcome, and the water to be overflowed cannot be overcome. The part is not included. The specific portion refers to, for example, a portion S1 (see FIG. 8) provided at a position overlapping the functional device 150 in the vertical direction in the upper end opening edge of the toilet bowl portion 12. The rear end 208a of the overflow edge 208 of the present embodiment is provided in front of the rear end 209 of the upper end opening of the toilet bowl portion 12. Here, "water overflows from the inside of the toilet bowl portion 12" is assumed, for example, when the drainage pipe line 16 is clogged with an object such as filth.

See 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 a plan view. The boundary portion 222 of the present embodiment is the upper opening 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 overflow edge 208 of the toilet bowl portion 12 has a height difference. As a result, the overflow edge 208 is provided with a lower portion 208b below the height center Ch of the overflow edge 208. Here, the high region 216 refers to a portion above the height center Ch of the overflow edge 208, and the low region 218 refers to a portion 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 the present embodiment, 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 in a plan view, and the low region 218 is provided in front of the boundary line Lb. .. It can be said that the lower region 218 is provided in front of the rear end 208a of the overflow edge 208. In the present embodiment, by providing the inclined surface 214 on the upper surface portion 24, the upper region 216 and the lower region 218 are formed on the upper surface portion 24.

The lower region 218 of the present embodiment is provided so as not to be connected to the boundary portion 222 of the upper surface portion 24 but to be connected to the outer peripheral edge portion 24a of the upper surface portion 24 of the toilet bowl main body 14 in a plan view. Such a low region 218 can guide the overflowing water so as to get over the low portion 208b of the overflow edge 208 to the outside of the toilet bowl body 14 through the low region 218 without passing through the rear space 220. FIG. 9 shows the induction direction Pa of the water overflowing from the overflow edge 208. When the inclined surface 214 constitutes the lower region 218 as in the present embodiment, the water passing over the lower region 218 is guided to flow downward (upward on the paper surface in FIG. 9) according to the gradient of the inclined surface 214.

The above-mentioned inclined surface 214 is provided on the upper surface portion 24 of the toilet bowl main body 14. The inclined surface 214 is provided so that the height is continuously lowered toward the front. The "height" here means the distance in the vertical direction from the horizontal plane passing through the floor surface F. The inclined surface 214 of the present embodiment is provided in a range from the front end portion 24b to the rear end portion 24c of the upper surface portion 24 of the toilet bowl main body 14. The inclined surface 214 is inclined so that the rear end portion 24c of the upper surface portion 24 is at the highest position and the front end portion 24b thereof is at the lowest position. The inclined surface 214 is uniformly inclined in the entire range of the front-rear direction X. In other words, the inclined surface 214 is provided so that the inclination with respect to the horizontal plane is equal in the entire range of the front-rear direction X.

The effect of the above third device will be described.

(C1) The lower region 218 of the toilet bowl body 14 can guide the overflowing water so as to get over the lower portion 208b of the overflow edge 208 to the outside of the toilet bowl body 14 without passing through the rear space 220. As a result, it becomes easy to avoid the situation where the water overflowing from the toilet bowl portion 12 flows into the rear space 220. The water overflowing from the toilet bowl portion 12 can be guided to either the front or side space of the toilet bowl body 14 by the lower region 218. Such a space is wider than the rear space 220, and it is easy to arrange a part of the user's body and cleaning tools. Therefore, even when water overflows from the toilet bowl portion 12, good cleanability can be obtained by guiding the water to such a place that is easy to clean.

In addition to this, it becomes easy to avoid a situation in which the electrical component 204 arranged in the rear space 220 gets wet due to the water overflowing from the toilet bowl portion 12. As a result, it is possible to protect the electronic components mounted on the electrical component 204.

An inclined surface 214 forming a high region 216 and a low region 218 is provided on the upper surface 24 of the toilet body 14. Therefore, the appearance becomes less noticeable as compared with the case where the step portion forming the high region 216 and the low region 218 is provided. As a result, good design can be obtained.

The inclined surface 214 of the toilet bowl body 14 is uniformly inclined. Therefore, since the inflection point is not provided on the inclined surface 214 of the toilet bowl main body 14, the appearance is neat and good design can be obtained. When transporting the toilet base (described later) of the toilet body 14 and the toilet body 14 itself, the toilet body 14 may be turned upside down. In this case, the receiving surface of the pedestal that comes into contact with the upper surface portion 24 of the toilet bowl body 14 can be made flat, and there is an advantage that the pedestal can be easily made.

The inclined surface 214 of the toilet body 14 is inclined so that the front end portion 24b thereof is at the lowest position. Therefore, the appearance is less noticeable than the provision of the inclined surface 214 which is inclined so that the intermediate position of the upper surface portion 24 in the front-rear direction X is at the lowest position, and good design can be obtained.

Other features related to the third device will be described. See FIG. The toilet seat 20 is provided with a plurality of legs 20a protruding downward from the lower surface of the toilet seat 20. The toilet seat 20 is supported by the inclined surface 214 of the toilet body 14 by placing a plurality of legs 20a on the inclined surface 214 of the toilet body 14. The 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 respect to the inclined surface 214 is unlikely to change. Therefore, the toilet seat 20 can be stably supported by the inclined surface 214 as compared with the case where the inclined surface 214 of the toilet body 14 is not uniformly inclined.

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

See FIGS. 10A and 10B. 10A and 10B are a cross-sectional view of the vacuum breaker 100 of FIG. 2 and a cross-sectional view taken along the line CC of FIG. FIG. 10A shows a state in which the valve body 240 is in the outside air shutoff 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 that forms a part of the liquid supply passage 90 inside. The main body 230 has an inflow passage 232 in which wash water flows in from the upstream side, an outflow passage 234 in which the wash water flowing in from the inflow passage 232 flows out, and a ventilation hole 236 that allows the internal space of the outflow passage 234 and the external space of the main body 230 to pass through. And. The inflow path 232 is provided so as to extend in the vertical direction. The upstream portion of the outflow path 234 is provided so as to extend in the horizontal direction.

The main body 230 further protrudes upward from the inner and lower surfaces of the outflow path 234 and forms a part of the inflow path 232 inside, and the inflow port of the inflow path 232 that opens at the upper end of the tubular portion 230a. 232a and the like. A valve seat 238 forming a peripheral edge of the inflow port 232a is provided at the upper end of the tubular portion 230a.

The vacuum breaker 100 includes a valve body 240 housed in the main body 230. The valve body 240 is supported so as to be movable up and down with respect to the main body 230. The valve body 240 can move between the outside air shutoff position Pa1 (see FIG. 10A) and the 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 to move from the outside air intake position Pa2 to the outside air shutoff position Pa1. When the washing water is not supplied from the inflow path 232, the valve body 240 moves downward due to its own weight to move from the outside air shutoff position Pa1 to the outside air intake position Pa2.

As shown in FIG. 10A, when the valve body 240 is at the outside air shutoff position Pa1, the inflow port 232a of the inflow path 232 is opened by being separated from the valve seat 238, and the inflow path 232 and the outflow path 234 communicate with each other. .. At this time, the valve body 240 closes the ventilation hole 236 and blocks the communication between the external space and the outflow path 234. As a result, the washing water is supplied from the inflow path 232 to the outflow path 234 without taking in the outside air into the outflow path 234 through the ventilation hole 236.

As shown in FIG. 10B, when the valve body 240 is at the outside air intake position Pa2, the valve body 240 closes the inflow port 232a of the inflow path 232 by contacting the valve seat 238, and the inflow path 232 and the outflow path 234 communicate with each other. Shut off. At this time, the valve body 240 has a vent hole 236 open so as to communicate with the external space and the outflow path 234. As a result, outside air is taken into the outflow passage 234 through the ventilation hole 236. Therefore, even when a negative pressure is generated on the upstream side of the inflow passage 232 of the liquid supply passage 90, the backflow can be prevented by taking in the outside air into the outflow passage 234 of the liquid supply passage 90.

Here, as shown in FIG. 2, the height of the portion of the overflow edge 208 that is overcome when water begins to overflow from the inside of the toilet bowl portion 12 is defined as Ha, and the height of the inflow port 232a of the vacuum breaker 100 is defined as Hb. At this time, as the difference ΔH1 between the height Hb of the inflow port 232a of the vacuum breaker 100 and the height Ha of the overflow edge 208 increases, the head pressure corresponding to the height of the difference increases the water in the outflow passage 234 of the vacuum breaker 100. It becomes easy to prevent backflow in the liquid supply passage 90. Therefore, in order to secure the required backflow prevention performance, the toilet device 10 is usually sold so that the inflow port 232a of the vacuum breaker 100 is arranged at a position separated by a predetermined distance from the overflow edge 208. It is required by national regulations. Due to this, when the overflow edge 208 does not have a height difference, there is a limit to lowering the position of the upper end of the vacuum breaker 100.

In the toilet bowl device 10 of the present embodiment, the high-level region 216 and the low-level 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 portion to be overcome when water starts to overflow from the inside of the toilet bowl portion 12 at the overflow edge 208 is lowered by ΔH2. can. Along with this, the position of the inflow port 232a of the vacuum breaker 100 can be lowered by the amount that the height is lowered by ΔH2. As a result, the position of the vacuum breaker 100 in the first cavity 28 can be lowered so that the position of the upper end of the vacuum breaker 100 is lowered. As a result, the vertical dimension of the toilet bowl device 10 can be reduced.

Next, the positional relationship of the discharge hole 250A for discharging the washing water into the toilet bowl portion 12 will be described. See FIG. As described above, the upper surface portion 24 of the toilet bowl body 14 is provided so as to be lowered toward the front side, which is one side of 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 an upper end side portion of the toilet bowl portion 12. The inner peripheral 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.

See FIG. The toilet device 10 includes discharge portions 252A and 252B for discharging the washing water for cleaning the inside of the toilet bowl portion 12 from the discharge holes 250A and 250B in the toilet bowl portion 12. The discharge portions 252A and 252B of the present embodiment form a part of the toilet bowl main body 14. The discharge portions 252A and 252B in the other embodiments may be provided separately from the toilet bowl main body 14. The discharge units 252A and 252B of the present embodiment include a first discharge unit 252A including a first discharge hole 250A and a second discharge unit 252B including a second discharge hole 250B. The first discharge hole 250A and the second discharge hole 250B are opened on the inner peripheral surface of the toilet bowl portion 12, specifically, the inner peripheral surface of the rim portion 242. The first discharge hole 250A and the second discharge hole 250B are opened to one side in the circumferential direction. Here, "one side in the circumferential direction" is counterclockwise on the paper of FIG. 11, and is also simply referred to as "counterclockwise" below.

The discharge portions 252A and 252B of the present embodiment include a water passage 254 formed on the outer peripheral side of the toilet bowl portion 12. Each of the discharge portions 252A and 252B discharges the washing water supplied from the liquid supply passage 90 to the water passage 254 counterclockwise from the discharge holes 250A and 250B, and creates a swirling flow that swirls counterclockwise in the toilet bowl portion 12. Form. The swirling flow cleans the inner peripheral surface of the toilet bowl portion 12 and discharges the filth in the toilet bowl portion 12 through the drainage pipe line 16.

Here, in a plan view, the left-right center line Lc1 that bisects the left-right dimension Dy of the upper end opening 12a of the toilet bowl portion 12, the front-rear center line Lc2 that bisects the front-rear dimension Dx, and the left-right center line Lc1. And the intersection Pi of the front-rear center line Lc2 are assumed. 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 with respect to the inner surface portion of the upper end opening 12a of the toilet bowl portion 12. The front-rear dimension Dx refers to the maximum dimension of the front-rear direction X with respect to the inner surface portion of the upper end opening 12a of the toilet bowl portion 12. In a plan view, the first reference line Lc3 in which the left and right center lines Lc1 are rotated by 45 ° in one side (counterclockwise in the present embodiment) in the circumferential direction around the intersection Pi, and the left and right center lines Lc1 are the circumferences around the intersection Pi. Assume a second reference line Lc4 rotated 45 ° to the other side of the direction. Here, "the other side in the circumferential direction" is clockwise on the paper of FIG. 11, and is also simply referred to as "clockwise" below.

The toilet bowl portion 12 is divided into eight divided regions Da1 to Da8 by the left and right center lines Lc1, the front-rear center lines Lc2, the first reference line Lc3, and the second reference line Lc4. The eight divided regions Da1 to Da8 are separate parts of the toilet bowl portion 12 divided by each line Lc1 to Lc4 as a boundary in a plan view. Of the eight division areas Da1 to Da8, the division area on the front side (one side of the front-rear direction X in the present embodiment) adjacent to the front-rear center line Lc2 in a counterclockwise direction is defined as the first division area Da1. Of the eight division areas Da1 to Da8, the remaining division areas provided in order from the first division area Da1 in the counterclockwise direction are designated as the second to eighth division areas Da2 to Da8, respectively.

At this time, the first discharge hole 250A is provided in any of a plurality of division regions Da2 to Da5 on the side opposite to the first division region Da1 with respect to the second reference line Lc4. The first discharge hole 250A is provided in the third division region Da3 as a division region satisfying this condition. The second discharge hole 250B is provided in the sixth division region Da6 in the present embodiment. This advantage will be explained.

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 (one side in the front-rear direction in this embodiment). In this case, the range in the vertical direction is usually wider in the rear portion than in the front portion of the rim portion 242.

(C2) Here, in the present embodiment, the first discharge hole 250A is provided in the division region Da3 on the side opposite to the first division region Da1 with respect to the second reference line Lc4. Therefore, rather than providing the first discharge hole 250A in the first division region Da1 and the eighth division region Da8, it becomes easier for the strong water wash water to reach the rear portion of the rim portion 242. Along with this, even when the vertical range to be washed is wide, such as the rear side portion of the rim portion 242, the rear side portion of the rim portion 242 can be easily washed satisfactorily with washing water having a strong water force.

In order to obtain the effect described here, the first discharge hole 250A may be provided in the second division region Da2, the fourth division region Da4, and the fifth division region Da5 in addition to the third division region Da3. The position of the second discharge hole 250B is not particularly limited, and may not be necessary.

In the present embodiment, the hollow portion 322 and the partition wall portion 324 are provided at the downstream end of the toilet drainage channel 46.

The shaft core C1 of the water channel forming surface 310 is eccentric to the upper side with respect to the shaft core C2 on the outer peripheral surface of the second pipe connecting portion 304 in a specific cross section. The water channel forming surface 310 of the present embodiment is provided with a first similar surface 326 similar to a part of the outer peripheral surface of the second pipe connecting portion 304 in a specific cross section. "Similarity" as used herein means that the two mentioned are similar as a whole, even if some of them are different due to either protrusions or recesses. good. The first similar surface 326 of the present embodiment includes the inner upper surface of the water channel forming surface 310, and is provided in a range straddling the axial core C1 of the water channel forming surface 310 up and down.

The water channel forming surface 310 of the present embodiment is provided with a first dissimilar surface 328 that is dissimilar to the outer peripheral surface of the second pipe connecting portion 304 in a specific cross section. The first non-similar surface 328 of the present embodiment is provided on the inner and lower surfaces of the water channel forming surface 310, and is connected to both ends in the circumferential direction of the first similar surface 326. The first non-similar surface 328 constitutes the upper surface of the partition wall portion 324 in the present embodiment. The first dissimilar surface 328 of the present 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 portion 314. The flat surface 330 is provided at the lowest position in the water channel forming surface 310 in a specific cross section. The flat surface 330 is provided over the entire area of the linear region 318 described above in the flow direction. As used herein, the term "parallel" is not limited to geometrically exactly parallel, but also includes almost parallel.

The hollow portion 322 has a bottomed shape that opens to the downstream end surface 304a of the second pipe connecting portion 304 and becomes a dead end 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 peripheral surface of the second pipe connecting portion 304, and a second dissimilar surface 334 that is dissimilar to the outer peripheral surface.

The second dissimilar surface 334 of the present embodiment is a flat surface parallel to the horizontal plane, like the first dissimilar surface 328.

The outer peripheral wall portion 26 extends around the axis C2 with the same thickness in the circumferential range in which the first similar surface 326 is provided. The outer peripheral wall portion 26 extends around the axis C2 with the same thickness in the circumferential range in which the second similar surface 332 is provided. The partition wall portion 324 is provided with a thickness equivalent to that of the outer peripheral wall portion 26 in a specific cross section.

The effect of the above fourth device will be described.

A water channel top portion 314 of the sealed water storage unit 52 is provided inside the second pipe connection portion 304 of the second pipeline component member 300. Therefore, as compared with the case where the water channel top portion 314 is provided on the upstream side of the second pipe connecting portion 304 of the second pipeline constituent member 300, the front-rear dimension of the second pipeline constituent member 300 can be reduced, and by extension, the size of the front and rear dimensions can be reduced. The front and rear dimensions of the toilet bowl device 10 can be reduced.

The shaft core C1 of the water channel forming surface 310 is eccentric to the upper side with respect to the shaft core C2 on the outer peripheral surface of the second pipe connecting portion 304 in a specific cross section passing through the water channel top portion 314 of the water sealing storage portion 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 as compared with the case where the outer peripheral surface of the second pipe connecting portion 304 and the entire water channel forming surface 310 have similar shapes. Along with this, the outer peripheral surface of the second pipe connecting portion 304 has a shape suitable for connection with the second piping member 302, and the water flow is different from the case where the outer peripheral surface of the second pipe connecting portion 304 has a similar shape. The shape of the inner and lower surfaces of the water channel forming surface 310 can be designed so as to realize the above.

In the present embodiment, in order to realize such different ways of flowing water, a flat surface 330 parallel to the horizontal plane is provided on the inner and lower surfaces of the water channel forming surface 310. This advantage will be described in detail with reference to FIGS. 14A and 14B. FIG. 14A is a cross-sectional view of a specific cross section of the second pipeline component 300 of the first modified example as viewed from the same viewpoint as in FIG. In the second pipeline constituent member 300 of the first modification, a concave curved surface similar to the outer peripheral surface of the second pipe connecting portion 304 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 portion 314.

As shown in FIGS. 14A and 14B, the second pipeline component 300 of the first modification and the second pipeline component 300 of the first embodiment have a predetermined height in a specific cross section passing through the water channel top 314. Consider the case where the water level rises by the amount of H0. In this case, according to the present embodiment, the flow rate of water that tends to exceed the waterway top 314 can be increased as compared with the first modification. This can be understood from the fact that the area of the portion shown by the hatching in FIG. 14B is larger than that of the portion shown by the hatching in FIG. 14A. Therefore, according to the present embodiment, when the water level of the water that is about to exceed the top of the water channel 314 is low, it becomes easy to secure a large drainage flow rate. The drainage flow rate here means the flow rate of water flowing through the drainage pipe line 16.

The outer peripheral surface of the second pipe connecting portion 304 of the second pipeline constituent 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 seal member 308 arranged between the second pipe member 302 and the second pipeline component 300 is positioned in the circumferential direction as compared with the case where the outer peripheral surface of the second pipe connection portion 304 has a polygonal shape. It becomes easy to stabilize regardless. Along with this, the sealing performance of the sealing member 308 becomes stable regardless of the circumferential position. As a result, it becomes easy to secure stable sealing performance between the second piping member 302 and the second pipeline constituent member 300.

Inside the second pipe connecting portion 304, a hollow portion 322 is provided below the water channel forming surface 310 in a specific cross section. As a result, the weight can be reduced by the amount of the hollow portion 322 as compared with the case where the hollow portion 322 inside the second pipe connecting portion 304 has a solid structure. In addition to this, as compared with such a case, waste meat is suppressed in the portion around the hollow portion 322 of the second pipe connecting portion 304. Along with this, the shape of the second pipe connecting portion 304 can be stabilized by suppressing the influence of sink marks and the like caused by the waste meat.

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

Next, another feature regarding the fourth device will be described. See FIG. The water channel top portion 314 of the second pipeline component 300 is provided with a water drop portion 340 that gradually decreases toward the downstream side in the internal water channel 306. The term "gradual" as used herein 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 drop portion 340 of the present 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 portion 314. It can also be considered that the water drop portion 340 is provided so as to form a step portion between them. The water drop portion 340 of the present embodiment is formed by the downstream end surface of the second pipeline constituent member 300, and forms a corner portion 342 with the water channel top portion 314. The water drop section 340 can drop the water that gets over the top 314 of the channel by using gravity.

As a result, the water that has passed over the top of the water channel 314 is dropped in the direction Pb on the downstream side of the water drop section 340 by using gravity, so that the water can easily flow to the downstream side in the internal water channel 306 of the drainage pipe 16. Become. Along with this, the resistance of water flowing in the drainage pipe line 16 can be reduced as compared with the case where the waterway top portion 314 does not have the water drop portion 340. As a result, it becomes easier to secure the drainage flow rate.

Next, a casting molding method for the toilet bowl base will be described. See FIG. The toilet bowl base is a semi-finished product necessary for obtaining the pottery body 14 made of earthenware, and is obtained by casting molding. The toilet base 350 of the toilet body 14 includes an upper surface side portion 352 including at least a part of the upper surface portion 24 of the toilet bowl body 14, and a toilet bowl side including most of the toilet bowl portion 12 and lower than the upper surface side portion 352. It includes a portion 354. The upper surface side portion 352 and the toilet bowl side portion 354 have a shape in which the toilet bowl main body 14 is divided into upper and lower parts. The toilet bowl side portion 354 is provided with the above-mentioned toilet drainage channel 46 and the second pipe connection portion 304.

The toilet body 14 is obtained by molding the toilet base of each of the upper surface side portion 352 and the toilet bowl side portion 354 by casting molding, joining them by adhesion or the like, and then passing through a firing step. Hereinafter, a method of obtaining the toilet bowl base material of the toilet bowl side portion 354 by casting molding will be mainly described.

See FIG. 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-absorbent material such as plaster. The molds 360, 362, 364, and 366 of the present embodiment include an upper mold 360 and a lower mold 362 arranged above and below the toilet bowl base, and a front mold 364 and a rear mold 366 arranged before and after the toilet bowl base. Toilet. 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 appearance surface of the toilet bowl side portion 354.

The posterior mold 366 forms at least a part of the portion facing the rear of the toilet bowl side portion 354. The rear mold 366 includes a molding recess 370 for molding the second pipe connection portion 304 of the toilet drainage channel 46, and a molding convex portion 372 for molding the hollow portion 322. The molding recess 370 is formed on the front surface of the rear mold 366 and is recessed backward. The molding protrusion 372 protrudes forward from the bottom of the molding recess 370.

Casting includes the following steps. First, a step of forming a mold space 374 for molding a toilet bowl base is performed by matching a plurality of molds 360, 362, 364, and 366. After that, a step of injecting uncured mud 376 into the mold space 374 is performed. By going through this step, the mud 376 is hardened along the surface of each mold 360, 362, 364, 366, and the toilet bowl base is formed by the hardened portion of the mud 376. After that, a step of discharging the uncured mud 376 remaining inside the hardened portion of the mud is performed. After that, the steps of removing the molds 360, 362, 364, and 366 from the toilet bowl base are performed. In this step, the rear mold 366 is moved relative to the toilet bowl base in the front-rear direction, so that the molded convex portion 372 of the rear mold 366 is extracted from the hollow portion 322 of the toilet bowl base 350.

The molding recess 370 of the rear mold 366 forms a closing wall 378 that closes the internal space of the toilet drainage channel 46 from the downstream side in the toilet base 350. After the above-mentioned demolding step, the closed wall 378 of the toilet bowl base 350 is cut off with a finger, a tool, or the like while the toilet bowl base material before firing is in a soft state.

As described above, by using the rear mold 366 provided with the molding concave portion 370 and the molding convex portion 372, the toilet bowl main body 14 having the hollow portion 322 provided inside the second pipe connecting portion 304 and below the water channel forming surface 310 can be easily provided. Obtained in.

The cord-like member 504 is pulled out from the drawer hole 516 via the first cavity portion 28, the insertion hole 522, and the hollow portion 520. The cord-like member 504 is pulled out from the drawer hole 516 without passing through the second cavity 40 provided on the inner side in the horizontal direction with respect to the step portion 510.

19 and 22 are referenced. The drawer hole 516 includes an opening 526 that opens in a direction intersecting the axial direction of a part of the cord-like member 504 arranged in the drawer hole 516. The "intersecting direction" here is the horizontal direction, more specifically, the backward direction in the present embodiment. In addition to the drawer hole 516, the opening 526 of the present embodiment is continuous with the rear wall portion 520a of the hollow portion 520 and the insertion hole 522, and these are also open toward the external space. An axially intermediate portion of the cord-like member 504 can be taken in and out of the direction Pf through the opening 526 between the drawer hole 516 and the external space. This direction Pf is a direction that intersects the axial direction of a part of the cord-shaped member 504 arranged in the drawer hole 516.

The cord-shaped member 504 of the present embodiment is inserted through a 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 part of the cord-like member 504 arranged in the through hole 528.

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

The effect of the above fifth device will be described.

The cord-shaped member 504 is arranged so as to cross the position overlapping the drainage pipe line 16 in the vertical direction in the horizontal direction. Therefore, even when the accessory device 500 and the mating device 502 are arranged on the left and right sides with respect to the left and right center position Px of the toilet bowl main body 14, it is not necessary to secure the arrangement space of the cord-shaped member 504 behind the drainage pipe line 16. .. Along with this, the toilet bowl main body 14 can be brought closer to the toilet room wall portion W, and the size of the toilet bowl device 10 can be reduced. In addition to this, the drainage socket 48 can be brought as close as possible to the toilet room wall portion W, and the range of the drainage core that can be handled can be expanded accordingly.

The cord-like member 504 is arranged below the drainage pipe line 16 so as to cross a position overlapping the drainage pipe line 16 in the vertical direction. Therefore, the space for arranging the cord-shaped member 504 is not required above the drainage pipe line 16, and it can be used as the space for arranging other accessory devices of the toilet bowl device 10. In addition to this, a portion below the drainage pipe line 16 that tends to be a dead space can be utilized as an arrangement space for the cord-shaped member 504. Therefore, it is possible to contribute to the miniaturization of the toilet bowl device 10 through space saving.

The cord-like member 504 is arranged in front of the descending pipe 58 of the drainage pipe 16 so as to cross a position overlapping the descending pipe 58 in the front-rear direction X. When the drainage pipe 16 includes the down pipe 58, the front of the down pipe 58 is more likely to become a dead space. According to the present embodiment, the portion that tends to be a dead space can be utilized as the arrangement space of the cord-shaped member 504. Therefore, it is possible to contribute to further miniaturization of the toilet bowl device 10 through space saving.

(F) The drawer hole 516 is formed in the outer peripheral wall portion 26 in a range below the downward step portion 510. Consider a case where a drawer hole 516 is formed in a portion (for example, an upper portion 512) of the outer peripheral wall portion 26 that is smoothly continuous without a step in the vertical direction. Compared with this case, by hiding by the upper portion 512 of the outer peripheral wall portion 26, it becomes difficult to visually recognize the drawer hole 516 when the toilet bowl device 10 is observed from the outside. This effect is particularly effective when the drawer hole 516 is formed in the stepped portion 510 of the outer peripheral wall portion 26. Along with this, the appearance of the toilet bowl device 10 becomes neat and easy, and the design of the toilet bowl device 10 can be enhanced.

The drawer hole 516 is formed in the lower part of the outer peripheral wall portion 26. Therefore, as compared with the case where the drawer hole 516 is formed in the upper part of the outer peripheral wall portion 26, it becomes difficult for the user in the standing posture to visually recognize the drawer hole 516. Along with this, the cord-shaped member 504 that is pulled out from the drawer hole 516 can also be made difficult to see, and good design can be obtained.

An accessory member having an outer diameter larger than that of the cord-shaped member 504 may be attached to a part of the cord-shaped member 504. This accessory member is, for example, a connector when the cord-like member 504 is a hose. The accessory member is an outlet when the cord-shaped member 504 is a cable. Depending on the size of the accessory member, the accessory member may be caught in the peripheral portion of the drawer hole 516. Therefore, depending on the size of the accessory member, there may be a case where the cord-shaped member 504 cannot be inserted into the drawer hole 516 from the end portion of the cord-shaped member 504.

In this respect, the intermediate portion of the cord-shaped member 504 of the present embodiment can be taken in and out through the opening 526 of the drawer hole 516. Therefore, the cord-shaped member 504 can be arranged in the drawer hole 516 regardless of the size of the accessory member.

Consider a case where a step portion 510 is provided on the rear wall portion of the outer peripheral wall portion 26 and a drawer hole 516 is formed in the step portion 510. In this case, a space for arranging the cord-shaped member 504 drawn out from the drawer hole 516 is required between the outer peripheral wall portion 26 and the toilet room wall portion W.

In this respect, in the present embodiment, a step portion 510 is provided on the outer wall portion 30 of the outer peripheral wall portion 26, and a drawer hole 516 is formed in the step portion 510. Therefore, it is not necessary to provide the rear wall portion on the outer peripheral wall portion 26. Along with this, the range of the drainage core that can be handled by the drainage socket 48 can be expanded by the amount of the rear wall portion of the second cavity portion 40.

The drawer hole 516 is formed so as to avoid the outer surface of the upper portion 512. Therefore, when the toilet bowl device 10 is observed from the outside, the drawer hole 516 becomes more difficult to see. Along with this, the design of the toilet bowl device 10 can be further enhanced.

The hollow portion 520 of the toilet bowl body 14 is usually a place where a mold is not arranged in casting molding, and tends to be a dead space. In the present embodiment, the cord-like member 504 is pulled out from the drawer hole 516 via the hollow portion 520. Therefore, a portion that tends to be a dead space can be utilized as an arrangement space for the cord-shaped member 504. Therefore, it is possible to contribute to the miniaturization of the toilet bowl device 10 through space saving.

Other features related to the fifth device will be described. See FIG. 24. One of the front-back direction X and the left-right direction Y is called a specific direction. The specific direction of this embodiment is the left-right direction Y. The outer peripheral wall portion 26 includes the above-mentioned outer wall portion 30 as an outer wall portion 532 facing the outside in a specific direction (horizontal direction Y in the present embodiment). The outer wall portion 532 separates the device inner space 506 and the outer space in a specific direction.

A cross section cut along a specific direction (horizontal direction Y in this embodiment) so as to pass through the drawer hole 516 is referred to as a specific cut surface. FIG. 24 shows a specific cut surface. In this specific cut surface, the downward direction along the reference surface Ps forming an angle of 60 ° with respect to the horizontal plane Ph is referred to as the reference direction Pg. The reference plane Ps becomes a plane extending downward toward the inside in a specific direction. This reference direction Pg assumes the line-of-sight direction of the user. When the reference surface Ps is in contact with the outer peripheral edge portion 510a of the step portion 510, the range inside the upper portion 512 of the outer wall portion 532 and above the reference surface Ps is hidden by the upper portion 512 of the outer wall portion 532. It means that it is placed in the same position.

At this time, the drawer 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 on this specific cut surface. It can be said that the drawer hole 516 is arranged at a position invisible from the reference direction Pg on the specific cut surface. As a result, it becomes more difficult to visually recognize the drawer hole 516 every time the toilet bowl device 10 is observed from the outside. Along with this, the design of the toilet bowl device 10 can be further enhanced.

This reference direction Pg is set based on the following concept. A side space 534 is formed between the toilet room wall portion W on the side of the toilet body 14 and the toilet body 14. The distance from the left and right center position Px of the toilet bowl body 14 to the toilet room wall portion W is usually at most 435 mm. Consider a case where an adult woman of a general physique kneels and cleans in a forward-bent posture using this side space 534 as a work space. It is assumed that the height of this adult female is 160 cm, and the viewpoint is located 40 cm (160 cm × 0.25) above the floor surface F. In this case, the position where the drawer hole 516 formed at the lower end of the outer wall portion 532 is most easily visible is when this viewpoint Vp is on the toilet room wall portion W.

Assuming that there is a viewpoint Vp here, assuming that the reference plane that passes through this viewpoint Vp and is in contact with the outer peripheral edge portion 510a of the step portion 510 is Ps', the angle θ0 of the 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 arranged at a position hidden by the upper portion 512 of the outer wall portion 532 when viewed from this viewpoint Vp. In other words, if it is inside the upper portion 512 of the outer wall portion 532 and above the reference surface Ps', the drawer hole 516 cannot be seen when an adult of a general physique cleans it. Will be.

Based on this idea, 60 ° is set as an angle that is more difficult to see than the angle θ0, and the concept set from that angle is the above-mentioned reference direction Pg. When the drawer hole 516 is arranged in an invisible position when viewed from the reference direction Pg, it can be considered that the drawer hole 516 becomes invisible when an adult with a general physique cleans it. This cleaning location is assumed to be a lateral space 534 on the side of the toilet body 14. In addition to this, the same effect can be obtained in the case of the space behind the toilet bowl main body 14, which is narrower than the lateral space 534.

In addition to this, 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 on this specific cut surface. Similarly, the lower portion 514 of the outer wall portion 523 is arranged in this specific cut surface at a position hidden by the upper portion 512 of the outer wall portion 532 as viewed from the reference direction Pg.

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

See FIGS. 19 and 26. The drawer holes 516 are individually provided on both the left and right sides with respect to the left and right center positions Px of the toilet bowl main body 14. In the present embodiment, the hollow portion 520 and the insertion hole 522 are also provided individually on the left and right sides with respect to the left and right center positions Px. When the mating device 502 is arranged at the position shown in FIG. 17, the cord-like member 504 is arranged so as to pass through the internal space of the hollow portion 520 on the right side and the insertion hole 522 in addition to the drawer hole 516 on the right side. When the mating device 502 is arranged at the position shown in FIG. 25, the cord-like member 504 is arranged so as to pass through the internal space of the hollow portion 520 on the left side and the insertion hole 522 in addition to the drawer hole 516 on the left side. In either case, the accessory device 500 remains arranged on one side (left side in the present embodiment) in the left-right direction with respect to the left-right center position Px. As a result, the cord-like member 504 can be pulled out from the space 506 in the device regardless of the arrangement position of the other 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 the flame can be prevented from entering the third arrangement space 116 accommodating 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 non-combustible material having a hardness sufficient to maintain a certain shape. As an example of this, the partition wall member 32 is constructed by using a metal such as iron, earthenware, or the like. The cushion material 176 may be constructed by using a non-combustible material. As an example of this, the cushion material 176 may be constructed by using a nonflammable fiber material such as glass wool or rock wool. At least one of the drawer hole 516, the insertion hole 522 and the through hole 528 may be closed by a nonflammable and flexible lid material. In order to realize this, the lid material may be sandwiched between the accessory device 500 and the partition wall member 32 (see the range S3 in FIG. 19). As an example of this lid material, a fiber material similar to the cushion material 176 may be used. Similar to the partition wall member 32, the portion of the accessory device 500 that sandwiches the lid material may be configured by using a non-combustible material having a hardness sufficient to maintain a certain shape.

(Second Embodiment) Refer to FIGS. 27 to 29. The toilet bowl device 10 of the present embodiment is mainly related to the above-mentioned first device. The liquid supply device 18 of the present embodiment is a tank device 402 including a tank 400. The tank device 402 includes tank units 404A and 404B provided on the liquid passage leading to the tank 400, in addition to the tank 400 for storing the liquid L supplied to the toilet bowl main body 14. The tank units 404A and 404B of the present 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 on the first liquid passage 406A that supplies liquid from the liquid supply source to the tank 400 as a liquid passage leading to the tank 400. The liquid supply source of the present embodiment is a water supply as in the first embodiment, and water is supplied as the liquid L. The valve unit 404A includes an on-off valve 408 and a first piping portion 410A constituting a downstream end portion of the first liquid passage. The on-off valve 408 is an electrically driven valve such as a solenoid valve, and can open and close the first liquid passage 406A under the control of a control unit (not shown). When the on-off valve 408 is in the valve open state, the liquid L flows into the tank 400 through the first piping portion 410A.

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

An example of the operation of the toilet bowl device 10 related to the tank device 402 will be described. The toilet bowl device 10 includes a float switch (not shown) for detecting whether or not the liquid level of the liquid L stored in the tank 400 exceeds the set liquid level. When the control unit determines that the liquid level in the tank 400 is equal to or lower than the set liquid level based on the detection result of the float switch, the control unit switches the on-off valve 408 from the closed state to the open state. As a result, the liquid L is supplied into the tank 400 through the first liquid passage 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, the control unit switches the on-off valve 408 from the valve open state to the valve closed state. As a result, the supply of the liquid L through the first liquid passage 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.

When the predetermined start condition is satisfied, the control unit starts driving the pump 412. This start condition is that, for example, a liquid supply start signal is input through an operation on 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 passage 406B. The control unit stops driving the pump 412 after a predetermined time has elapsed from starting the driving of the pump 412. By going through the above series of operations, a set amount of liquid L is supplied from the tank 400.

The tank 400 will be described in detail. The tank 400 is arranged at a position spaced apart from the toilet bowl portion 12 and the toilet drainage channel 46 of the toilet body 14. The shape of the toilet bowl body 14 may vary due to shrinkage due to drying in the molding process. Therefore, if the tank 400 is arranged at a position where it comes into contact with the toilet bowl portion 12 and the toilet bowl drainage channel 46 of the toilet bowl main body 14, if the shape of the toilet bowl portion 12 or the like has a large variation, the tank 400 is arranged at the target position. It can be difficult to do. 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 concealed from the outside by the outer peripheral wall portion 26 of the toilet bowl device 10, similarly to the toilet bowl portion 12 of the toilet bowl main body 14 and the toilet bowl drainage channel 46. Suppose that at least one of the toilet bowl portion 12, the toilet drainage channel 46, and the tank 400 of the toilet body 14 is covered with a dew-proof material. Even in this case, the dew-proof material can be concealed by the outer peripheral wall portion 26 of the toilet bowl device 10, and both good design and dew-proof measures can be achieved.

At least a part of the tank 400 is arranged in the first arrangement space 112 described in the first embodiment. The tank 400 includes a first storage unit 420 arranged in the first arrangement space 112. In addition to this, the tank 400 includes a second storage unit 422 arranged on at least one side in the left-right direction Y with respect to the first storage unit 420. In order to satisfy this condition, the second storage unit 422 may be arranged at a position deviated from the first arrangement space 112 in the front-rear direction X. The second storage unit 422 of the present embodiment is arranged at a position overlapping the first arrangement space 112 in the front-rear direction X in a side view. This condition is not mandatory. A storage chamber 424 for storing the liquid L is formed inside the tank 400. The storage chamber 424 is continuously formed inside the first storage unit 420 and the second storage unit 422.

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

At least a part of the first storage portion 420 is provided so as to be above the above-mentioned central position P3 of the internal water channel 306 of the drainage pipe line 16. The storage chamber 424 of the tank 400 is also provided so as to satisfy this condition. The liquid level Ls of the liquid L stored in the tank 400 is also provided so as 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 in the left-right direction Y from the first arrangement space 112. It can be said that the tank 400 is provided so as to protrude in the left-right direction Y from a portion overlapping the drainage pipe line 16 in the up-down direction Z in the rear view. The tank 400 of the present embodiment is provided so as to protrude from the first arrangement space 112 on both sides in the left-right direction Y.

The effect of the above toilet bowl device 10 will be described.

(E1) As described above, the tank 400 is arranged in the first arrangement space 112 behind the ascending pipeline 54, which tends to be a dead space. The tank 400 of the present embodiment is arranged in the first arrangement space 112 between the ascending pipe 54 and the descending pipe 58, which are particularly prone to dead space. Therefore, as in the case of (A1) described above, the size of the toilet bowl device 10 can be reduced as compared with 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 in the left-right direction Y from the first arrangement space 112. Therefore, as described above, a part of the tank 400 is arranged at a position shifted in the left-right direction Y with respect to the first arrangement space 112 which tends to be a dead space. Therefore, the capacity of the tank 400 can be increased without increasing the size of the toilet bowl device 10. In relation to such an effect, the tank 400 may project to at least one side of the first arrangement space 112.

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

(E4) The second storage unit 422 is individually arranged on both sides in the left-right direction Y with respect to the drainage pipe line 16. Therefore, the capacity of the tank 400 can be increased by the amount of the individual second storage unit 422.

Other features of the toilet bowl device 10 of the present embodiment will be described. Similar to the first embodiment, a second arrangement space 118 for arranging a part of the drainage pipe line 16 is provided below the tank 400. As a result, it is possible to realize a design in which the drainage pipe line 16 is arranged below the tank 400, as in the above-mentioned (A2). As a result, the degree of freedom regarding the arrangement position of the drainage pipe 16 is improved.

Also in this embodiment, a part of the drainage socket 48 is arranged in the second arrangement space 118 as “a part of the drainage pipe line 16”. Therefore, as in the above-mentioned (A3), the adjustment allowance for the length of the drainage socket 48 in the front-rear direction X can be increased by the amount of the second arrangement space 118, and the range of the drainage core that can be handled can be expanded.

(E5) The tank 400 of the present embodiment is mounted on the mounting portion 122 of the toilet bowl device 10 as in the first embodiment. The tank 400 is fixed to the toilet bowl main body 14 by using a screw or the like (not shown) in a state where the tank 400 is mounted on the mounting portion 122. The tank 400 is arranged at a position spaced from the floor surface F and is supported by the toilet bowl body 14. As a result, good workability can be obtained when the tank 400 is installed, as in the case of (A4) described above.

The first pipe connection portion 66 of the first pipeline component 62 is arranged above the first arrangement space 112. The first pipe connecting portion 66 is connected to a first piping member 64 (drainage socket 48 in this embodiment) provided behind the first arrangement space 112. Therefore, as in 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 the lower side of the toilet bowl main body 14. In addition to this, as in the above-mentioned (A7), the first arrangement space 112 is expanded in the front-rear direction X as compared with the case where the first pipe connection portion 66 of the drainage pipe line 16 is arranged behind the first arrangement space 112. Can be done.

(E6) The toilet bowl device 10 is configured so that the tank 400 can be taken in and out in the horizontal direction with respect to the first arrangement space 112, as in the first embodiment. As a result, similarly to the above-mentioned (A5), when the tank 400 is mounted on the mounting portion 122, it is not necessary to lift or turn the toilet bowl body 14 upside down, and good workability can be obtained.

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

The pipe receiving portions 426A and 426B do not protrude toward the outside of the tank 400, but protrude toward the storage chamber 424 side of the tank 400. It can be said that the pipe receiving portions 426A and 426B do not protrude outward with respect to the peripheral wall portion 430 provided around the pipe receiving portions 426A and 426B of the tank 400, but protrude inward with respect to the peripheral wall portion 430.

(E7) As a result, the structure around the tank 400 and the pipe receiving portions 426A and 426B are less likely to interfere with each other as compared with the case where the pipe receiving portions 426A and 426B protrude toward the outside of the tank 400. The "structure" here is the partition member 32 in the present embodiment. Along with this, the peripheral wall portion 430 of the tank 400 can be brought closer to the structure. As a result, when the tank 400 is arranged in the vicinity of the structure, the capacity of the tank 400 can be increased.

A 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 bowl main body 14 is a wall-mounted type. The drainage pipe 16 of this modified example 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 as in the embodiment of FIG. 27. The tank 400 includes a first storage unit 420 and a second storage unit 422 (not shown), as in the modified example of FIG. 27.

Also in this example, the components described in (E1) to (E7) described above are provided, and the effects corresponding to those explanations can be obtained.

33 and 34 are shown. This modification is different from the embodiments shown in FIGS. 28 and 29 in that a plurality of tank devices 402 are provided. 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 valve unit 404A and a pump unit 404B in addition to the tank 400 (hereinafter referred to as the first tank 400A) as in the second embodiment. The second tank device 402B includes a valve unit 404A and a pump unit 404B in addition to the tank 400 (hereinafter referred to as the second tank 400B) 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 in the first cavity 28 of the toilet bowl 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 the flush water for cleaning the toilet bowl as the liquid L, and the second tank 400B stores the water for the local cleaning device as the liquid L. By supplying the washing water for cleaning the toilet bowl to the toilet bowl portion 12 of the toilet bowl main body 14, it is possible to discharge the filth in the toilet bowl portion 12 and clean the inside of the toilet bowl portion 12. The water for the local cleaning device is supplied into the toilet bowl portion 12 of the toilet bowl main body 14 via the local cleaning device.

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

The upper portion of the second tank 400B is arranged on the opposite side of the drainage pipe line 16 from the second storage portion 422 of the first tank 400A in the left-right direction Y.

Also in this example, the components described in (E1) to (E3) and (E5) to (E7) described above are provided, and the effects corresponding to those explanations can be obtained. In addition to this, when liquids L for different purposes are stored in a plurality of tanks 400, the capacity of one tank 400 can be increased by the amount arranged in the first arrangement space 112.

Specific examples of the liquid L stored in the plurality of tanks 400 are not particularly limited. For example, the liquid L for the spray device described above may be stored in any of the tanks 400. As the liquid L, in addition to the washing water supplied from the water supply, purified water obtained by purifying the washing water with a modifier such as a filter medium may be used. When purified water is used, there is an advantage that the scale component adhering to the toilet bowl body 14 can be removed by purified water. In addition to 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 portion 12 by being supplied to the inside of the toilet bowl portion 12 of the toilet bowl body 14, for example. The water for the local cleaning device may be stored in the tank 400 as hot water by preheating. As a result, it is possible to increase the flow rate of the hot water injected from the local cleaning device.

Unlike the embodiment, the pump unit 404B may supply the liquid L to the toilet bowl main body 14 via a mechanical device such as a local cleaning device or a spray device. In this case, such a mechanical device will be provided on the above-mentioned second liquid passage 406B.

(Regarding the second device) The first cavity 28 and the second cavity 40 may be provided with a rear wall portion that separates the internal space and the external space of the respective cavities 28 and 40 in the front-rear direction.

The notch 178 may not be formed at the rear end 30a of the outer side wall 30. The cutout portion 178 may be formed at a portion other than the lower end portion of the outer wall portion 30.

In order to obtain the effect of (B1) described above, the toilet bowl device 10 may be fixed in a state where the rear end portion of the outer wall portion 30 of the toilet bowl device 10 is not touched on the toilet room wall portion W. This assumes a case where there is a gap between the toilet room wall portion W and the outer wall portion 30 of the toilet bowl device 10.

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

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

See FIGS. 35 and 36. The toilet device 10 of this modified example includes a waterproof cover member 188 that covers and closes the continuous opening 186 of the toilet body 14. As a result, it is possible to prevent water or the like from entering the inside of the toilet bowl body 14 through the continuous opening 186 of the toilet bowl body 14. Along with this, it is possible to protect the electrical components 204 and the like arranged inside the toilet bowl main body 14. The cover member 188 of this modification is provided at a position aligned with the rear end portion 30a of the outer wall portion 30 of the toilet bowl body 14 in the front-rear direction X. In addition to this, the cover member 188 may be provided in front of the rear end portion 30a of the outer wall portion 30 of the toilet bowl main body 14.

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

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

In addition to this, when the wall-mounted toilet body 14 is used, a cover member that covers the internal space of the first cavity 28 from below may be used. This cover member is assumed to cover, for example, 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 modified example is composed of a cover member 190 provided separately from the toilet bowl main body 14. In this modification, a pair of cover members 190 form 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 range extending from the rear end portion 30a of the outer wall portion 30 to the front-rear direction X. The cover member 190 of this modification constitutes a part of the first cavity portion 28.

The cover member 190 is detachably fixed to the toilet bowl body 14 via a fastener 192. A plurality of fixed portions 191 for fixing the cover member 190 are provided on the toilet bowl main body 14 at intervals in the front-rear direction X. The fastener 192 of this modification is composed of a pair of hook-and-loop fasteners attached to the toilet bowl 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 body 14 so that the relative position of the cover member 190 with respect to the toilet body 14 in the front-rear direction X can be adjusted. Specific examples of the fastener 192 satisfying this condition are not particularly limited. As a specific example of this, the fastener 192 may also be composed of a combination of bolts and elongated holes, a magnet, and the like.

Thereby, the rear end portion 30a of the outer wall portion 30 formed by the cover member 190 can be brought into contact with the toilet room wall portion 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 portion W. By adjusting the position of the toilet bowl body 14 in the front-rear direction X in this way, the position of the drainage pipe line 16 can also be adjusted, and it is possible to cope with variations in the position of the drainage core in the front-rear direction X. That is, even when the outer wall portion 30 of the toilet bowl device 10 is applied to the toilet room wall portion W, it is possible to cope with the variation in the position of the drainage core by changing the position of the toilet bowl main body 14 in the front-rear direction X.

The cover member 190 may form the entire outer wall portion 30, unlike the modified example of FIG. 37. As described above, the cover member 190 may form at least a part of the outer wall portion 30.

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

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

The high-level region 216 and the low-level region 218 of the upper surface portion 24 of the toilet bowl body 14 may be formed with a stepped portion instead of the inclined surface 214. This step portion is provided, for example, so that the height gradually decreases toward the front.

In order to obtain the effect of (C1) described above, the position of the lower region 218 of the upper surface portion 24 of the toilet bowl 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 of the front-rear direction X overlapping the overflow edge 208 and the left-right direction Y in a plan view. In addition to this, as shown in FIG. 38B, the lower region 218 may be provided only in a part of the range in the left-right direction Y that overlaps the overflow edge 208 and the front-rear direction X in a plan view. In any case, the lower region 218 may be able to guide the water over the lower portion 208b of the overflow edge 208 to the outside of the toilet bowl body 14 without passing through the rear space 220. It is considered that the lower region 218 may be able to guide water over the lower portion 208b of the overflow edge 208 to either the front or the side of the toilet bowl body 14. In both the examples of FIGS. 38A and 38B, the high-level region 216 of the upper surface portion 24 of the toilet bowl 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. The slope of the slope 214 may differ depending on the position in the front-rear direction. For example, the slope that forms the high region 216 and the slope that forms the low region 218 may be different.

Unlike the embodiment, the inclined surface 214 may be inclined so that the intermediate 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 intermediate position of the upper surface portion 24 in the front-rear direction is at 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 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 inclined surface 214 satisfying this condition may be uniformly inclined.

The toilet seat 20 may be supported at a position other than the inclined surface 214 of the upper surface portion 24 of the toilet 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 to this, the "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.

In explaining an example in which the height difference of the upper surface portion 24 of the toilet bowl body 14 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 bowl main body 14 may be provided so as to be lowered 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 range in the vertical direction is usually wider in the front side portion than in the rear side portion of the rim portion 242.

See FIG. 39. In this case, the first division region Da1 is provided in 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 regions are sequentially provided on one side in the circumferential direction from the first divided region Da1. In this case, in order to obtain the effect of (C2) described above, in the same manner as described above, in any of the plurality of divided regions Da2 to Da5 on the side opposite to the first divided region Da1 with respect to the second reference line Lc4. It is preferable to provide the first discharge hole 250A. As a result, even when the front side portion of the rim portion 242 has a wide range in the vertical direction to be washed, the front side portion of the rim portion 242 can be easily washed well with washing water having a strong water force.

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

The shaft core C1 of the water channel forming surface 310 may be provided at the same core as the shaft core C2 of the second pipe connecting portion 304 in a specific cross section passing through the water channel top portion 314.

The shaft core C1 of the water channel forming surface 310 is eccentric upward with respect to the shaft core C2 of the second pipe connecting portion 304 in a specific cross section passing through the water channel top portion 314, and a flat surface 330 is formed on the inner and lower surfaces of the water channel forming surface 310. It is not necessary to provide. For example, an arc surface or the like that is convex upward may be provided on the inner and lower surfaces of the water channel forming surface 310.

When the flat surface 330 is provided on the inner and lower surfaces of the water channel forming surface 310, an example in which the flat surface 330 is formed by the second pipeline constituent member 300 has been described. The flat surface 330 may be formed by a member different from the second pipeline constituent member 300, for example, the second piping member 302.

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

The overflow edge 316 may be formed by the apex of an arcuate region extending in an arcuate manner toward the downstream side in the drainage pipe 16.

The water channel top 314 does not have to be provided with a water drop 340. For example, the waterway top 314 may be provided with a curved surface that continuously decreases toward the downstream side.

See FIG. 40. In this modified example, the structure around the second pipe connecting portion 304 of the second pipeline constituent member 300 is different from that of the embodiment shown in FIG. In this modified example, the second pipeline component 300 is the toilet bowl main body 14 as in the embodiment of FIG. On the other hand, the second piping member 302 is a drainage socket 48, unlike the embodiment shown in FIG.

The waterway top 314 of this modification is not provided with a linear region 318 (see FIG. 12) that extends linearly toward the downstream side. It can be considered that the downstream end of the waterway top 314 is composed of the downstream end of the ascending surface 312.

The highest point 314a of the water channel top 314 is provided on the upstream side of the drainage pipe 16 with respect to the downstream end surface 304a of the second pipe connection portion 304. Similar to the embodiment of FIG. 12, the water channel top portion 314 of this modified example is provided with a water drop portion 340 that gradually decreases toward the downstream side in the internal water channel 306. The water drop portion 340 of this modified example is provided so as to form a discontinuous height difference between the inner and lower surfaces of the second pipe connecting portion 304 and the water channel top portion 314. The water drop portion 340 of this modified example is provided inside the second pipe connecting portion 304 on the upstream side of the internal space of the descending pipe 58 of the drainage pipe 16.

As a result, the internal waterway 306 is located downstream of the highest point 314a of the waterway top 314, as compared with the case where the highest point 314a of the waterway top 314 is aligned with the downstream end surface 304a of the second pipe connection portion 304. A large space of 380 can be secured. This space 380 is formed between the second piping member 302 and the water channel top 314 on the side horizontally opposite to the water sealing 56 with respect to the water channel top 314. Therefore, it becomes easy for the water that has passed over the top portion 314 of the water channel to flow toward the downstream side in the internal water channel 306, and it becomes easy to secure a large drainage flow rate. In particular, when the inner wall surface of the second piping member 302 is located near the downstream end surface 304a of the waterway top 314, the space 380 is widened in the internal waterway 306 on the downstream side of the maximum 314a of the waterway top 314. It's hard to do. Even in such a case, the effect described here can be effectively obtained.

In addition to this, as compared with the case where the downstream end surface 304a of the second pipe connection portion 304 is arranged at the position where the downstream end surface 304a of the second pipe connection portion 304 is aligned with the highest point 314a of the water channel top portion 314, the second pipe connection portion 304 is arranged in the flow direction of the internal water channel 306. Can be lengthened. Along with this, the length of the second pipe connecting portion 304 necessary for ensuring the sealing property between the second pipe connecting portion 304 and the second pipe connecting portion 304 can be secured.

See FIG. 41. In this modified example as well, as in the modified example of FIG. 40, the water drop portion 340 is provided at the water channel top portion 314 of the second pipeline constituent member 300. In this modification, the structure of the drainage socket 48 is different from that in FIG. 40. In this modification, the drainage socket 48 includes an oblique pipeline portion 382 provided in the descending pipeline 58 and a first straight pipe portion 384 provided in the descending pipeline 58.

The oblique pipeline portion 382 is provided at a position behind the first arrangement space 112 so as to overlap the first arrangement space 112 in the front-rear direction. The oblique pipeline portion 382 is provided so as to extend diagonally downward, specifically backward and downward, toward the downstream side. The cross-sectional area of the cross section orthogonal to the pipe axis direction of the inner peripheral surface of the oblique pipeline portion 382 is provided so as to gradually decrease toward the downstream side. The first straight pipe portion 384 is connected to the downstream side of the diagonal pipe portion 382, and extends vertically downward toward the downstream side. The boundary portion 386 between the oblique pipeline portion 382 and the first straight pipe portion 384 is provided at a position behind the first arrangement space 112 and overlapping the first arrangement space 112 in the front-rear direction.

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

This advantage will be explained. Consider a case where an object such as toilet paper dropped from the water drop portion 314 of the water channel top 314 is placed on the inner and lower surfaces of the diagonal pipeline portion 382. In this case, since the oblique pipeline portion 382 is provided so as to extend diagonally downward, it becomes easy for an object on the inner and lower surfaces thereof to flow to the downstream side. Therefore, as compared with the case where the second straight pipe portion 388 of the drainage socket 48 is provided in a wide range, the object dropped from the water dropping portion 314 is less likely to be clogged. At the same time, the first arrangement space 112 can be expanded in the front-rear direction as compared with the case where the drainage socket 48 does not have the oblique pipeline portion 382. Therefore, the size of the liquid supply device 18 arranged in the first arrangement space 112 can be increased.

From the viewpoint of obtaining this effect, it is preferable to satisfy the conditions described below. The maximum flow rate of the water flowing down from the water dropping unit 340 in one washing operation is called Lmax (liter / sec). The one-time cleaning operation here means an operation of supplying a predetermined amount of water from a water supply device (not shown) for cleaning the toilet bowl portion 12. The upstream end 382a of the inner and lower surfaces of the diagonal pipeline portion 382 is provided at a position where it does not hit the water flow when the water flow having the maximum flow rate Lmax flows down from the water dropping portion 314 in a parabolic shape.

In addition to this, from the viewpoint of obtaining the above-mentioned effect, it is preferable that the upstream end 382a of the diagonal pipeline portion 382 satisfies the following conditions. Specifically, the upstream end 382a of the diagonal conduit portion 382 is preferably provided within 20 mm in the horizontal direction on the downstream side of the water channel top 314 with respect to the highest point 314a of the water channel top 314, and is preferably within 10 mm. It is more preferable that it is provided within the range.

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

The partner device 502 may be arranged in the device interior space 506 of the toilet bowl device 10, unlike the embodiment. In this case, the cord-like member 504 is arranged only in the device internal space 506 and is not pulled out from the device internal space 506. The partner device 502 arranged in the device internal space 506 may be, for example, an antifreeze heater for preventing the water in the toilet drainage channel 46 from freezing, a hot water heater for heating the 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, for example, a power source such as a motor used for a local cleaning device, a deodorizing device, or the like.

Specific examples of the cord-shaped member 504 are not particularly limited. The cord-shaped member 504 may be arranged above the drainage pipe line 16 at a position overlapping the drainage pipe line 16 in the vertical direction. The drainage pipe 16 does not have to include the descending pipe 58. The cord-like member 504 does not have to be arranged in front of the descending conduit 58.

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

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

The toilet bowl body 14 does not have to include the hollow portion 520. The cord-like member 504 may be pulled out from the drawer hole 516 without passing through the hollow portion 520 of the toilet bowl body 14.

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

See FIG. 42. The partner device 502 includes a first partner device 502A and a second partner device 502B. The first partner device 502A is a water stopcock as in the embodiment of FIG. The second partner device 502B is an outlet that serves as an external power source for supplying commercial power. The other devices 502A and 502B are arranged on the other side (right side in this modification) in the left-right direction Y with respect to the left-right center position Px of the toilet bowl main body 14, as in the embodiment of FIG.

The cord-shaped member 504 includes a first cord-shaped member 504A that connects the accessory device 500 and the first partner device 502A, and a second cord-shaped member 504B that connects the accessory device 500 and the second partner device 502B. The first cord-shaped member 504A is a hose that supplies water, as in the embodiment of FIG. The second cord-shaped member 504B is a cable for transmitting electric power. The second cord-shaped member 504B supplies electric power from an outlet as the second partner device 502B to a power supply circuit (not shown) mounted on the accessory device 500. The power supply circuit supplies the power supplied from the external power supply to other accessory devices.

The plurality of cord-shaped members 504 are drawn out from the common first extraction hole 516A via the common first insertion hole 522A. Therefore, the structure of the toilet bowl device 10 can be simplified as compared with the case where the plurality of cord-shaped members 504 are pulled out from the individual drawer holes 516.

The plurality of cord-shaped members 504 are arranged so as to cross the drainage pipe line 16 and the overlapping position Pc overlapping in the vertical direction in the horizontal direction. Therefore, even when there are a plurality of cord-shaped members 504, it is not necessary to secure a space for arranging the cord-shaped members 504 behind the toilet bowl main body 14. Along with this, even when there are a plurality of cord-shaped members 504, as described above, it is possible to realize the miniaturization of the above-mentioned dimensions of the toilet bowl device 10.

As described above, the number of cord-shaped members 504 is not particularly limited. When there are a plurality of cord-shaped members 504, it is sufficient that at least one cord-shaped member 504 is arranged so as to cross a position where it overlaps the drainage pipe line 16 in the vertical direction. The plurality of cord-shaped members 504 may be pulled out from the individual drawer holes 516, unlike the modified example of FIG. 42.

See FIG. 43. The drawer hole 516 is formed on the outer peripheral wall portion 26 below the step portion 510. Specifically, the drawer hole 516 is formed in the lower portion 514 of the outer peripheral wall portion 26. The drawer hole 516 of this example is also formed in the outer peripheral wall portion 26 in a range below the step portion 510. The drawer hole 516 of this example is composed of the above-mentioned notch 178. Like the notch 178, the drawer hole 516 of the present embodiment includes an opening 526 that opens backward and downward. The cord-like member 504 is pulled out from the drawer hole 516 via the first cavity portion 28 and the second cavity portion 40. Also in this case, as in the effect of (F) described above, the drawer hole 516 becomes difficult to see when the toilet device 10 is observed from the outside because it is hidden by the upper portion 512 of the outer peripheral wall portion 26.

The embodiments and modifications have been described in detail above. The above-described embodiments and modifications are merely specific examples. The shapes referred to in the present specification naturally include shapes that are deviated from the referred shapes by an error such as a dimensional error or a manufacturing error. Many design changes such as change, addition, and deletion of components can be made in the contents of the embodiment and the modified example. In the above-described embodiment, the content capable of such a design change is emphasized by adding the notation "embodiment".
