JP-A-2017-66618

When the inventor of the present application examined the disclosed technology of Patent Document 1, it was recognized that there is room for improvement in the following points. Water such as urine may be transmitted downward on the outer peripheral wall. Under the structure of Patent Document 1, due to the influence of surface tension, water flows from the portion above the step portion of the outer peripheral wall portion to the portion below the step portion via the lower surface of the step portion. It is easy to convey. Therefore, there is a possibility that water may infiltrate into a small gap between the outer peripheral wall and the floor (hereinafter referred to as an on-floor gap). Since it is difficult to remove the water that enters the gap on the floor with a cleaning tool, it tends to remain on the floor for a long period of time. This can cause problems, and improvement is desired.

One of the objects of the present disclosure is to provide a technique capable of realizing measures against water intrusion into the gap above the floor.

One aspect of the present disclosure for solving the above-mentioned problems is a toilet bowl device. A toilet device of a certain aspect has a toilet bowl portion, a toilet bowl main body having an upper surface portion through which the upper end opening of the toilet bowl portion opens, and an outer periphery forming an external exposed surface below the outer peripheral edge portion of the upper surface portion. The wall portion, the stepped portion provided downward on the outer peripheral wall portion and formed with the lower portion on the outer side and the higher portion on the inner side, and the portion below the stepped portion on the outer peripheral wall portion are formed. It includes a lower portion that is arranged at a position that fits inside the lowest portion of the lower portion.

Hereinafter, embodiments will be described. The same components are designated by the same reference numerals, and duplicate description will be omitted. In each drawing, for convenience of explanation, components are omitted, enlarged, or reduced as appropriate. The drawings shall be viewed according to the orientation of the symbols. The shapes referred to in the present specification naturally include not only shapes that exactly match the shapes referred to, but also shapes that are deviated by an error such as a dimensional error or a manufacturing error.

(First Embodiment) Refer to FIGS. 1 to 4. Hereinafter, the positional relationship of each component will be described using three directions orthogonal to each other. This direction is the front-rear direction X, the left-right direction Y, and the up-down direction Z. The front-back direction X and the left-right direction Y are horizontal directions, and the up-down direction Z is a vertical direction. The front-back direction X and the left-right direction Y correspond to the front-back and left-right directions of a user who sits in a normal posture on a toilet seat (not shown) attached to the toilet body 12. In addition to this, the "diameter direction" and "circumferential direction" of the outer peripheral wall portion 24 will be described. The "circumferential direction" refers to a direction that orbits around the center line CL when the vertical straight line passing through the center of the outer shape formed by the outer peripheral wall portion 24 is defined as the center line CL in a plan view. The "diametrical direction" refers to a direction orthogonal to the center line CL.

The toilet device 10 includes a toilet body 12 that constitutes a Western-style toilet. In addition to this, the toilet device 10 includes a toilet seat (not shown) arranged on the upper surface portion 16 (described later) of the toilet body 12.

The toilet bowl body 12 of the present embodiment is made of earthenware. The material of the toilet bowl body 12 is not particularly limited, and may be, for example, resin or the like. The toilet bowl main body 12 of the present embodiment is a floor-standing type arranged on the floor F of the toilet room, and is fixed to the floor F by using a fixing component (not shown).

The toilet body 12 includes a toilet bowl portion 14 for receiving filth, an upper surface portion 16 through which the upper end opening of the toilet bowl portion 14 opens, and a toilet bowl drainage channel 18 connected to the bottom portion of the toilet bowl portion 14. The toilet drainage channel 18 is connected to a drainage pipe (not shown) installed in the building via a piping member (not shown). The toilet bowl drainage channel 18 includes a sealed water storage unit 22 for storing the sealed water 20. The sealing water 20 blocks the flow of air in the toilet bowl drainage channel 18.

The toilet bowl device 10 includes an outer peripheral wall portion 24 that forms an externally exposed surface below the outer peripheral edge portion 16a of the upper surface portion 16. The externally exposed surface refers to a surface exposed to the external space 26. The external space 26 as used herein refers to a space provided outside the toilet bowl body 12 when the toilet bowl body 12 is in a state before being fixed to the toilet room. The entire outer peripheral wall portion 24 of the present embodiment is provided as a part of the toilet bowl main body 12. The outer peripheral wall portion 24 is placed on the floor F and supports a load such as a toilet bowl portion 14 integrated with the outer peripheral wall portion 24.

The outer peripheral wall portion 24 of the present embodiment forms a cavity portion 28 with the toilet bowl portion 14. The cavity 28 is formed so as to extend from the front of the toilet bowl 14 to the left and right sides of the toilet bowl 14 (not shown). The outer peripheral wall portion 24 of the present embodiment is arranged at intervals with respect to the toilet bowl drainage channel 18 and surrounds the toilet bowl drainage channel 18.

The outer peripheral wall portion 24 has a front wall portion 30 provided on the front side with respect to the toilet bowl portion 14, a pair of side wall portions 32 provided on both left and right sides with respect to the toilet bowl portion 14, and a rear portion with respect to the toilet bowl portion 14. A rear wall portion 34 provided on the side is provided. The front wall portion 30 of the present embodiment is connected to the side wall portion 32 via a front bending portion 31 that is convex outward. The rear wall portion 34 of the present embodiment is connected to the side wall portion 32 via a rear bending portion 33 that is convex outward. The outer peripheral wall portion 24 of the present embodiment is provided over the entire circumference around the center line CL.

The toilet device 10 of the present embodiment includes a storage portion 36 formed inside the outer peripheral wall portion 24 behind the toilet bowl portion 14. The accommodating portion 36 is open to the upper surface portion 16 of the toilet bowl main body 12. An object (not shown) is accommodated in the accommodating portion 36. The object to be contained is, for example, a functional device including a casing and at least one internal device housed in the casing. The internal device is, for example, a local cleaning device that cleans a local part of a seated person who sits on the toilet seat.

The toilet device 10 has a step portion 40 provided downward on the outer peripheral wall portion 24, an upper portion 42 forming an upper portion from the outer peripheral edge portion 40a of the step portion 40 on the outer peripheral wall portion 24, and a step portion on the outer peripheral wall portion 24. It includes a lower portion 44 that constitutes a portion lower than the portion 40. In the present embodiment, each of the upper portion 42, the step portion 40, and the lower portion 44 is composed of a part of the toilet bowl main body 12.

The upper portion 42 of the present embodiment constitutes a portion of the outer peripheral wall portion 24 below the outer peripheral edge portion 16a of the upper surface portion 16. The upper portion 42 of the present embodiment is not provided with a portion protruding outward on the way toward the lower side. This condition is satisfied in a part of the circumferential direction range from the front end portion of the outer peripheral wall portion 24 to the rear in the present embodiment. As a result, a neat appearance can be obtained with respect to the upper portion 42 of the outer peripheral wall portion 24. In order to realize this, the upper portion 42 of the present embodiment has a shape that extends inward toward the lower side. In addition to this, in order to realize this, the upper portion 42 may have a shape extending vertically downward. That is, the upper portion 42 may be composed of a combination of a shape extending inward toward the lower side and a shape extending vertically downward.

The lower portion 44 is a portion of the outer peripheral wall portion 24 that is lower than the step portion 40 and constitutes an upper portion from the lower end 24a of the outer peripheral wall portion 24. The lower portion 44 of the present embodiment is provided so as to extend inward as it goes downward.

The step portion 40 is provided so as to have a difference in outer diameter dimension between the upper portion 42 and the lower portion 44. The step portion 40 of the present embodiment is provided at the lower portion of the outer peripheral wall portion 24, specifically, at the lower end portion of the outer peripheral wall portion 24. Let the total length of the outer peripheral wall portion 24 in the vertical direction Z be Lh (see FIG. 2). The lower part of the outer peripheral wall portion 24 means a range from the lower end position of the outer peripheral wall portion 24 to the position Pa where Lh × 0.5. The lower end portion of the outer peripheral wall portion 24 means a range from the lower end position of the outer peripheral wall portion 24 to the position Pb where Lh × 0.2.

The step portion 40 is provided on each of the front wall portion 30 and the side wall portion 32 of the outer peripheral wall portion 24. It can be considered that the step portion 40 is provided on the outer peripheral wall portion 24 in a part of the circumferential direction range from the front end portion of the outer peripheral wall portion 24 to the rear. The step portion 40 of the present embodiment is also provided on the rear wall portion 34 of the outer peripheral wall portion 24. It can be considered that the step portion 40 of the present embodiment is provided in a range extending over the entire circumference around the center line CL of the outer peripheral wall portion 24.

See FIG. The lower portion 44 forms an above-floor gap G exposed to the external space 26 with the floor F.

The step portion 40 includes a downward lower surface 40b continuous with the outer peripheral edge portion 40a of the step portion 40, and a wall portion 40c that separates the inner space 46 and the outer space 26 inside the outer peripheral wall portion 24. On the lower surface 40b of the step portion 40, an outer low portion 48 and an inner high portion 50 are formed. As used herein, the terms "outside" and "inside" mean the outside and inside in the radial direction. The high portion 50 is provided at a position higher than the low portion 48 in the cross section cut along the radial direction.

The step portion 40 of the present embodiment includes a first slope portion 52 extending from the lowest portion 48a of the lower portion 48 to the highest portion 50a of the higher portion 50. The first slope portion 52 of the present embodiment has a flat shape in a cross section cut along the radial direction. The first slope portion 52 of the present embodiment is formed on the lower surface of a wall portion having the same thickness from the outside to the inside. The first slope portion 52 forms a corner portion that is convex downward with the upper portion 42. This corner portion constitutes a lower portion 48 of the step portion 40 and has a curved surface shape in the present embodiment.

The outer peripheral wall portion 24 of the present embodiment is provided inside the highest portion 50a of the higher portion 50 of the step portion 40, and includes a second slope portion 54 that extends downward and is continuous with the lower portion 44. The second slope portion 54 forms an upwardly concave corner portion with the first slope portion 52. This corner portion constitutes a high-level portion 50 of the step portion 40.

The lower portion 44 is arranged at a position within the lower portion 48a of the lower portion 48. The lower portion 44 does not protrude outward from the lowest portion 48a of the lower portion 48. This condition is satisfied in a cross section cut along the radial direction.

The effects of the above ingenuity will be explained. See FIG. Consider a case where water W such as urine is transmitted downward to the upper portion 42 of the outer peripheral wall portion 24. This case occurs, for example, when urinating in the toilet bowl portion 14, the droplets generated in the toilet bowl portion 14 are transmitted outward through the upper surface portion 16.

The stepped portion 40 of the present embodiment is formed with an outer lower portion 48 and an inner higher portion 50. Therefore, in the step portion 40, it becomes difficult for water W to be transmitted from the low portion 48 to the high portion 50 due to surface tension. Along with this, the water W can be easily separated downward from the lower portion 48 of the step portion 40 by its own weight. As a result, it becomes difficult for water to be transmitted from the upper portion 42 of the outer peripheral wall portion 24 to the lower portion 44 via the lower surface 40b of the step portion 40.

In addition to this, the lower portion 44 of the outer peripheral wall portion 24 is arranged at a position within the lower portion 48 of the step portion 40. Therefore, the water W separated from the lower portion 48 of the step portion 40 can be dropped to a position separated from the lower end 24a of the outer peripheral wall portion 24. As a result, it becomes easy to avoid a situation in which the water W separated from the lower portion 48 of the step portion 40 directly hits the lower portion 44.

(A) Combined with the above, it becomes easy to avoid the situation where water infiltrates the gap G on the floor, and the problem caused by the infiltration of water can be avoided. This problem is, for example, dirt, odor, corrosion, etc. caused by water in the underfloor gap G. According to the present embodiment, water can be dropped at a position distant from the underfloor gap G to the outside with respect to the floor F. At such a position, it is easier to reach a cleaning tool such as a cloth as compared with the underfloor gap G. Therefore, it can be easily removed by dropping the water W at such a position, and it becomes easy to avoid a situation where the water W remains on the floor F for a long period of time.

In addition to this, a method of using a joint material such as caulking or tape that closes the gap G on the floor can be considered in order to implement measures against water intrusion. However, when a joint material is used, it is necessary to construct the joint material after installing the toilet bowl device 10. In addition to this, regular replacement of joint materials is also required. According to the toilet bowl device 10 of the present embodiment, it is only necessary to devise the cross-sectional shape of the outer peripheral wall portion 24 in order to realize measures against water intrusion. Therefore, the labor required for the construction and replacement of the joint material can be reduced, and the labor required for measures against water intrusion can be reduced. In addition to this, since the joint material does not appear on the appearance of the toilet bowl device 10, good designability can be obtained.

The step portion 40 can be used as a handle for hanging a finger from the lower side, making it easier to carry the toilet bowl device 10. As a result, when the hand is extended downward from above the toilet bowl device 10, the fingertips of the toilet device 10 can be easily reached at the place where the hand is to be used, as compared with the case where the lower end 24a of the outer peripheral wall portion 24 is used as a hand. Along with this, it is possible to facilitate the transportation work and the installation work of the toilet bowl device 10. In particular, even when the upper portion 42 of the outer peripheral wall portion 24 does not have a portion protruding outward, the toilet device 10 can be easily carried by using the step portion 40 as a handle.

When used in such an application, it is preferable that the high position portion 50 is provided at a position where the end node portion of the finger touches when the joint portion of the finger is applied to the outer peripheral edge portion 40a of the step portion 40. The joint portion here means any of the first joint portion and the second joint portion of any of the fingers of the user, the second finger to the fifth finger. The user here assumes an adult with an average physique in the country where the toilet bowl device 10 is implemented. As a result, when a finger is hung on the step portion 40 from below so as to affix the joint portion of the finger to the outer peripheral edge portion 40a of the step portion 40, the fingertip can be applied to the higher portion 50. Therefore, the range in which the finger touches the lower surface 40b of the step portion 40 can be widened. Along with this, the load of the toilet bowl device 10 can be received in a wide range of fingers, and the toilet bowl device 10 can be stably handled in a lifted state.

(B) The lower portion 44 of the outer peripheral wall portion 24 is provided so as to extend inward as it goes downward. As a result, the lower end 24a of the outer peripheral wall portion 24 can be arranged at a position separated inward from the lower portion 48 of the step portion 40. Therefore, it is possible to further avoid the situation where the water W separated at the lower portion 48 infiltrates into the above-floor gap G.

The step portion 40 includes a first slope portion 52 that extends upward from the lower portion 48 toward the inside. Therefore, in forming the high portion 50 and the low portion 48 in the step portion 40, it is possible to make it difficult for a local change in cross-sectional shape to occur around the low portion 48 as compared with the case where a small protrusion portion (described later) is formed. .. Along with this, it becomes easier to secure the strength around the lower portion 48.

(C) The step portion 40 is provided at the lower end portion of the outer peripheral wall portion 24. Therefore, it is difficult for the user in the standing posture to visually recognize the step portion 40, and good design can be obtained.

See FIG. The toilet body 10 includes a flat floor contact surface 74 that contacts the floor F. An outer curved surface portion 76 that is continuous with the floor contact surface 74 of the toilet bowl body 10 and has a convex curved surface shape is provided on the lower edge portion of the outer peripheral surface of the lower portion 44 of the outer peripheral wall portion 24. This makes it easier to insert the cleaning tool into the underfloor gap G and remove the dirt that has entered the underfloor gap G.

See FIGS. 5 and 7. In the cross section cut along the radial direction passing through the front wall portion 30, the first tangent line in contact with the outer peripheral surface of the upper portion 42 of the outer peripheral wall portion 24 and the outer peripheral surface of the lower portion 44 is defined as Lt1 with respect to the horizontal plane Ph. Let θ1 be the angle formed by the first tangent line Lt1. In the cross section cut along the radial direction passing through the side wall portion 32, the tangent line in contact with the outer peripheral surface of the upper portion 42 of the outer peripheral wall portion 24 and the outer peripheral surface of the lower portion 44 is Lt2, and the second tangent line with respect to the horizontal plane Ph. Let θ2 be the angle formed by Lt2. At this time, the angle θ1 with respect to the front wall portion 30 is smaller than the angle θ2 with respect to the side wall portion 32. As a result, in the front wall portion 30, the lower portion 44 of the outer peripheral wall portion 24 is arranged at a deep position inside the upper portion 42.

Water such as urine is more likely to fall in front of the toilet body 12 than on the side of the toilet body 12. According to the above configuration, even if water falls on the floor F in front of the toilet bowl body 12, the droplets are easily received by the upper portion 42 of the outer peripheral wall portion 24. As a result, it becomes easier to avoid the situation where the droplets infiltrate into the underfloor gap G.

(Second Embodiment) Refer to FIG. The lower surface 40b of the stepped portion 40 of the present embodiment has a flat shape on the cut surface along the radial direction. In this embodiment, the lower surface 40b is provided parallel to the horizontal plane. The stepped portion 40 of the present embodiment includes a protruding portion 56 protruding downward from the lower surface 40b of the stepped portion 40. The protrusion 56 constitutes a lower portion 48 of the step portion 40. The protrusion 56 of the present embodiment is provided on the outer peripheral edge portion 40a of the step portion 40. The protrusion 56 of the present embodiment is a ridge extending in the circumferential direction. The protrusion 56 of the present embodiment has an arc shape that is convex downward.

As a result, the high portion 50 and the low portion 48 can be formed on the step portion 40 only by partially providing the protrusion 56 on the lower surface of the step portion 40. Therefore, even if the outer diameter of the outer peripheral wall portion 24 is not increased in size, the high portion 50 and the low portion 48 can be easily formed in the step portion 40. Along with this, it is possible to realize measures against water intrusion while realizing miniaturization of the outer peripheral wall portion 24.

In addition to this, the toilet bowl device 10 of the present embodiment has a configuration corresponding to the effects described in the above-mentioned (A) to (C), and the described effects can be obtained.

See FIG. In order to obtain the same effect as that of the embodiment of FIG. 8, the protrusion 56 may be provided on the lower surface 40b of the step portion 40 at a position separated from the outer peripheral edge portion 40a. As described above, the position where the protrusion 56 is provided is not particularly limited.

(Third Embodiment) Refer to FIG. A groove 78 that opens downward is formed on the floor contact surface 74 of the present embodiment. The groove portion 78 may be continuous in an annular shape on the outer peripheral wall portion 24, for example. An inner curved surface portion 80 that is continuous with the floor contact surface 74 and has a convex curved surface shape is provided on the outer peripheral side lower edge portion of the groove portion 78. The radius of curvature of the outer curved surface portion 76 of the present embodiment is larger than the radius of curvature of the inner curved surface portion 80 in the cross section cut along the radial direction.

The floor contact surface 74 includes a continuous region 82 that is continuous in the range from the outer curved surface portion 76 to the inner curved surface portion 80. A minute gap may be formed between the continuous region 82 of the floor contact surface 74 and the floor F due to the influence of the fine unevenness of the floor contact surface 74 and the floor F. In this case, the water that has entered the underfloor gap G may enter the inside through the minute gap due to the influence of surface tension. If this amount of penetration becomes too large, stains may occur in a wide range of the floor F.

From the viewpoint of avoiding this, the smaller the horizontal dimension L1 of the continuous region 82 is, the more preferable it is. From this point of view, it is preferable that the horizontal dimension L1 of the continuous region 82 is smaller than the horizontal dimension L2 (see FIG. 5) of the step portion 40 in the cross section cut along the radial direction. In addition to this, in the cross section cut along the radial direction, the horizontal dimension L1 of the continuous region 82 is the horizontal dimension L3 of the outer curved surface portion 76 having a single radius of curvature and the inner curved surface portion 80 having a single radius of curvature. It is preferable that the value is smaller than the total value of the horizontal dimension L4. The horizontal dimension referred to here refers to a dimension along the horizontal direction. The horizontal dimension L1 of the continuous region 82 here means the dimension from the inflection point between the outer curved surface portion 76 and the continuous region 82 to the inflection point between the inner curved surface portion 80 and the continuous region 82. The horizontal dimension L1 of the continuous region 82 is preferably 0.6 mm or more from the viewpoint of ensuring the strength against a local concentrated load.

(Fourth Embodiment) Refer to FIG. The lower portion 44 of the outer peripheral wall portion 24 of the present embodiment is provided so as to extend vertically downward.

The toilet device 10 includes a fixing component 58 for fixing the toilet body 12 to the floor F. The fixed component 58 of the present embodiment has an L shape as a whole. The fixing component 58 is fixed to the floor F by the first screw member 60. A second screw member 62 penetrating the outer peripheral wall portion 24 of the toilet bowl body 12 is screwed into the fixed part 58. The toilet body 12 is fixed to the floor F via the fixing component 58 and the screw members 60 and 62, respectively.

A through hole 64 is formed in the outer peripheral wall portion 24 inside the lower portion 48 of the step portion 40. The through hole 64 allows the inner space 46 and the outer space 26 inside the outer peripheral wall portion 24 to pass through. The through hole 64 of the present embodiment functions as an insertion hole through which the object to be inserted 66 passes. The inserted object 66 here is the above-mentioned second screw member 62 in the present embodiment. The through hole 64 of the present embodiment is formed in the lower portion 44 of the outer peripheral wall portion 24 as a position satisfying this condition.

At the opening position of the through hole 64 in the outer peripheral wall portion 24, as described above, it is difficult for water W transmitted downward through the upper portion 42 of the outer peripheral wall portion 24 to be transmitted. Therefore, even when the through hole 64 is formed in the outer peripheral wall portion 24, it is easy to avoid a situation in which water W enters the inside of the outer peripheral wall portion 24 through the through hole 64.

In addition to this, the opening position of the through hole 64 in the outer peripheral wall portion 24 is a position that is hard to see as compared with the upper portion 42 of the outer peripheral wall portion 24. Therefore, even when the through hole 64 is formed in the outer peripheral wall portion 24, the through hole 64 becomes inconspicuous and good design can be obtained.

See FIG. An inner curved surface portion 80 that is continuous with the floor contact surface 74 of the outer peripheral wall portion 24 and has a convex curved surface shape is provided on the lower edge portion of the inner peripheral surface of the lower portion 44 of the present embodiment. The floor contact surface 74 includes a continuous region 82 that is continuous in the range from the outer curved surface portion 76 to the inner curved surface portion 80. The continuous region 82 of the present embodiment also satisfies the same conditions regarding the horizontal dimensions L1 to L4 as those of the first embodiment.

In addition to this, the toilet bowl device 10 of the present embodiment has a configuration corresponding to the effects described in the above-mentioned (A) and (C), and the described effects can be obtained.

(Fifth Embodiment) Refer to FIGS. 13 and 14. The toilet device 10 of the present embodiment includes an accessory part 68 attached to the toilet body 12. The accessory 68 of the present embodiment includes a casing 70 and at least one device 72 housed in the casing 70. The device 72 exerts a predetermined function attached to the toilet bowl main body 12. The device 72 is, for example, a heater, a cooler, an air purifier, a deodorizer, a light emitter, and the like. This air purifier may exert an air purifying function by releasing active species generated by plasma discharge. The accessory component 68 of the present embodiment is detachably attached to the toilet bowl body 12 via a attachment mechanism (not shown). The mounting mechanism is, for example, a screw structure, a plurality of magnets, a snap-fit structure, or the like.

The accessory part 68 constitutes a part of the outer peripheral wall portion 24 inside the lower portion 48. This condition is satisfied by the casing 70 of the accessory 68 in the present embodiment. The accessory component 68 of the present embodiment constitutes a lower portion 44 of the outer peripheral wall portion 24 as a portion satisfying this condition. The outer peripheral wall portion 24 is composed of the toilet bowl main body 12 and the accessory component 68.

The accessory component 68 of the present embodiment constitutes a part of each of the front wall portion 30 and the side wall portion 32 of the outer peripheral wall portion 24. The accessory component 68 can be regarded as forming a part of the outer peripheral wall portion 24 in a part of the circumferential direction range from the front end portion of the outer peripheral wall portion 24 to the rear. The accessory component 68 of the present embodiment also constitutes a part of the rear wall portion 34 of the outer peripheral wall portion 24. The accessory component 68 of the present embodiment can be regarded as forming a part of the outer peripheral wall portion 24 in the range extending over the entire circumference of the outer peripheral wall portion 24.

The stepped portion 40 of the outer peripheral wall portion 24 of the present embodiment is also provided with the first slope portion 52 and the second slope portion 54 described in the embodiment of FIG. The first slope portion 52 of the present embodiment is formed on the outer surface of a wall portion having a thickness that gradually decreases from the outside to the inside.

The accessory part 68 constitutes a part of the outer peripheral wall portion 24 inside the lower portion 48. At the position where the accessory component 68 is provided, as described above, it is difficult for the water W transmitted downward through the upper portion 42 of the outer peripheral wall portion 24 to be transmitted. Therefore, even when the accessory component 68 constitutes a part of the outer peripheral wall portion 24, it is easy to avoid a situation where the accessory component 68 becomes dirty.

The accessory part 68 constitutes a part of the outer peripheral wall portion 24. Therefore, as compared with the case where the accessory component 68 is arranged inside the outer peripheral wall portion 24, the accessory component 68 can be easily attached to and detached from the toilet bowl main body 12.

In addition to this, the position where the accessory component 68 is provided on the outer peripheral wall portion 24 is a position that is hard to see as compared with the upper portion 42 of the outer peripheral wall portion 24. Therefore, even when the outer peripheral wall portion 24 is composed of the accessory component 68, the accessory component 68 becomes inconspicuous and good design can be obtained.

In addition to this, the toilet bowl device 10 of the present embodiment has a configuration corresponding to the effects described in the above-mentioned (A) to (C), and the described effects can be obtained.

Other modifications of each component will be described.

The toilet body 12 may be fixed to a wall body rising from the floor F of the toilet room instead of the floor F of the toilet room.

A part of the upper portion 42 of the outer peripheral wall portion 24 may also be provided separately from the toilet bowl main body 12. The outer peripheral wall portion 24 does not have to include the rear wall portion 34.

The step portion 40 may be provided on the outer peripheral wall portion 24, and its specific position is not particularly limited. The step portion 40 may be provided, for example, above the outer peripheral wall portion 24, or may be provided below the outer peripheral wall portion 24 above the lower end portion of the outer peripheral wall portion 24.

When the water W in the toilet bowl portion 14 is transmitted outward through the upper surface portion 16, the water is more likely to reach the front wall portion 30 and the side wall portion 32 as compared with the rear wall portion 34 of the outer peripheral wall portion 24. Therefore, it is preferable that the step portion 40 is provided on the front wall portion 30 and the side wall portion 32 in order to take measures against the intrusion of water into the above-floor gap G. The step portion 40 does not have to be provided on the rear wall portion 34. In addition to this, the step portion 40 may be provided only on one of the pair of side wall portions 32, or may be provided only on the front wall portion 30.

The specific configuration for forming the low-level portion 48 and the high-level portion 50 in the step portion 40 is not limited to the content of the embodiment. Both the slope portions 52 and 54 and the protrusion 56 may be provided on the step portion 40.

In addition to the insertion hole, the through hole 64 may function as, for example, a ventilation hole for passing an air flow. This ventilation hole becomes either an air supply path or an exhaust path of the air flow generated by the fan when the fan is arranged inside the toilet bowl device 10. This fan is incorporated in, for example, a deodorizer, a heater, a cooling machine, and the like. This fan may be incorporated into the device 72 of the accessory 68. This assumes, for example, the case where a through hole 64 is formed in the casing 70 of the accessory part 68.

The through hole 64 may be formed inside the outer peripheral wall portion 24 rather than the lower portion 48. As a position satisfying this condition, unlike the embodiment, the through hole 64 may be formed at a high position 50 of the stepped portion 40 of the outer peripheral wall portion 24.

Specific examples of the insert 66 are not particularly limited. The insert 66 may be, for example, a cord-like member that connects a device incorporated in the toilet bowl device 10 and an external device. This cord-like member is a flexible and cord-like long object. The cord-like member is, for example, a hose connected to a water stopcock as an external device, a cable connected to an external power source as an external device, or the like.

The accessory part 68 may be attached to the toilet bowl main body 12, and specific examples thereof are not particularly limited. The accessory part 68 may be the above-mentioned device 72 itself or the above-mentioned fixed part 58.

Unlike the embodiment, the accessory component 68 may form the high portion 50 of the step portion 40 inside the low portion 48.

Unlike the embodiment, the accessory component 68 may form only a part of the peripheral wall portion 24 in the circumferential direction. The accessory component 68 may constitute, for example, only the front wall portion 30 and the side wall portion 32 of the outer peripheral wall portion 24.

See FIG. The first illuminator 86A may be attached to the lower surface 40b of the step portion 40. The first illuminator 86A is arranged so as to fit above the lowest portion 48a of the lower portion 48. In addition to this, the second illuminator 86B may be attached to the lower portion 44 of the step portion 40. The illuminators 86A and 86B are LEDs and the like. Instead of the illuminators 86A and 86B described here, a sensor such as a human body detection sensor may be attached to the same location.

See FIG. In the cross section cut along the radial direction, the inward and downward directions forming an angle of 60 ° with respect to the horizontal plane Ph are referred to as the reference direction Pg. This reference direction Pg assumes the line-of-sight direction of the user. The lower portion 44 may be arranged at a position hidden by the upper portion 42 when viewed from the reference direction Pg. As a result, when the toilet bowl device 10 is observed from the outside, the lower portion 44 can be made difficult to see, and the design of the toilet bowl device 10 can be enhanced.

This reference direction Pg is set based on the following concept. A side space 90 is formed between the toilet room wall portion W on the side of the toilet body 12 and the toilet body 12. The distance from the position of the center line CL of the toilet bowl body 12 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 90 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 lower portion 44 is most easily visible is when this viewpoint Vp is on the toilet room wall portion W.

Assuming that the viewpoint Vp is here, the angle θ0 of the reference surface Ps with respect to the horizontal plane Ph, which passes through the viewpoint Vp and is in contact with the lower end of the upper portion 42, is 56. It becomes 5 °. At this time, the range above the reference plane Ps is arranged at a position hidden by the upper portion 42 when viewed from this viewpoint Vp. In other words, the area above this is placed in a position hidden by the upper portion 42 when cleaned by an adult of general physique.

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. This cleaning location is assumed to be a side space 90. In addition to this, the same effect can be obtained in the case of the space behind the toilet body 12 which is narrower than the side space 90.

The embodiments and modifications have been described in detail above. The above-described embodiments and modifications are merely specific examples. 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". However, design changes are allowed even if there is no such notation. The hatching attached to the cross section of the drawing does not limit the material of the object to which the hatching is attached.

Any combination of the above components is also valid. For example, any explanatory matter of other embodiments and modifications may be combined with the embodiment. In addition to this, any explanatory matter of the embodiment and other modified examples may be combined with the modified example. For example, the through hole 64 of the embodiment of FIG. 8 may be combined with the accessory 68 of FIG.
