Moreover, in FIG. 2, the display of the cover 13 is omitted.

水洗大便器１００は、洋式の水洗式大便器であり、便器本体１０と、機能部１２と、カバー１３と、を備える。以下では、前後左右は、ユーザが通常の姿勢で水洗大便器１００に着座した状態における前後左右をいうものとする。 The flush toilet 100 is a Western-style flush toilet, and includes a toilet body 10 , a functional part 12 and a cover 13 . Hereinafter, the front, rear, left, and right refer to the front, rear, left, and right when the user is seated on the flush toilet 100 in a normal posture.

便器本体１０は、例えばセラミック材料や樹脂材料から形成される。便器本体１０は、便鉢１４と、上面部１６と、便器排水路１８と、外周壁部２０と、を含む。便鉢１４は、略漏斗状の部材であり、汚物を受ける。便鉢１４の上部の内周縁は、上面部１６の下面１６ａとともに、旋回流を生成するための通水路１５を構成する。 The toilet body 10 is made of, for example, a ceramic material or a resin material. The toilet body 10 includes a toilet bowl 14 , an upper surface portion 16 , a toilet drainage channel 18 and an outer peripheral wall portion 20 . The toilet bowl 14 is a substantially funnel-shaped member and receives waste. The inner peripheral edge of the upper portion of the toilet bowl 14 constitutes, together with the lower surface 16a of the upper surface portion 16, a water passage 15 for generating a swirling flow.

便器排水路１８は、一端は便鉢１４の流出口１４ａに通じ、他端は排水管（不図示）に通じている。便鉢１４に洗浄水が供給されると、汚物は洗浄水とともに便器排水路１８内に流れ、そこから排水管に排出される。外周壁部２０は、便鉢１４の外周側や便器排水路１８を隠すよう、それらを囲む。 One end of the toilet drainage channel 18 communicates with the outflow port 14a of the toilet bowl 14, and the other end communicates with a drainage pipe (not shown). When the flush water is supplied to the toilet bowl 14, the filth flows into the toilet drain path 18 together with the flush water and is discharged from there into the drain pipe. The outer peripheral wall part 20 surrounds the outer peripheral side of the toilet bowl 14 and the toilet drainage channel 18 so as to hide them.

上面部１６は、便鉢１４の上端周縁に接続されている。上面部１６は、便鉢１４の上端周縁の形状よりも僅かに小さい略楕円形状の開口部４０を有する。この開口部４０は、便鉢１４の上方に位置する、上面部１６の上面１６ｂは平坦に形成され、便座（不図示）が閉じているときに便座が当接する当接面として機能する。また、上面部１６の上面１６ｂは、機能部１２が載置される載置面として機能する。また、上面部１６は、その内部に空洞部４６を含む。 The upper surface portion 16 is connected to the upper peripheral edge of the toilet bowl 14 . The upper surface portion 16 has an approximately elliptical opening 40 slightly smaller than the shape of the upper peripheral edge of the toilet bowl 14 . The opening 40 is located above the toilet bowl 14. The upper surface 16b of the upper surface portion 16 is formed flat and functions as a contact surface against which the toilet seat (not shown) contacts when the toilet seat is closed. Further, the upper surface 16b of the upper surface portion 16 functions as a mounting surface on which the functional portion 12 is mounted. The upper surface portion 16 also includes a cavity portion 46 therein.

機能部１２は、その一部が上面部１６に載置された状態で、便鉢１４の後方側の上部に設けられる。機能部１２は、便器本体１０に付随して用いられる電装品であり、本実施の形態では、局部を洗浄するための局部洗浄装置３４と、臀部を乾燥するための乾燥装置３６と、便鉢１４内で発生する臭気を脱臭するための脱臭装置３８とを含む。 The functional part 12 is provided on the upper part of the toilet bowl 14 on the rear side with a part thereof placed on the upper surface part 16 . The functional unit 12 is an electrical component used in conjunction with the toilet body 10. In the present embodiment, the functional unit 12 includes a private cleaning device 34 for cleaning the private region, a drying device 36 for drying the buttocks, and a toilet bowl. and a deodorizing device 38 for deodorizing odors generated within 14 .

カバー１３は、便器本体１０の後方に設置される。カバー１３は、便器本体１０の後方側を覆い隠し、水洗大便器１００の意匠性を確保する。 The cover 13 is installed behind the toilet body 10 . The cover 13 covers the rear side of the toilet body 10 and secures the design of the flush toilet 100.例文帳に追加

機能部１２は、不図示の昇降機構により、浮上する。具体的には、機能部１２は、機能部１２の少なくとも一部が上面部１６に載置している下降位置（図１（ａ）の位置）と、機能部１２が上面部１６に載置していない上昇位置（図１（ｂ）の位置）との間を昇降する。機能部１２を上昇位置に上昇させることによって、ユーザは、上面部１６の後方側を拭き掃除できる。なお、機能部１２は、ユーザが手で持ち上げることによって昇降されてもよい。 The functional part 12 is lifted by an elevating mechanism (not shown). Specifically, the functional part 12 is placed in a lowered position (position shown in FIG. 1A) where at least a part of the functional part 12 is placed on the upper surface part 16, and It moves up and down between the raised position (the position in FIG. 1(b)) where it is not. By raising the functional portion 12 to the raised position, the user can wipe the rear side of the upper surface portion 16 . Note that the functional unit 12 may be lifted and lowered by the user's hand.

図３は、便器本体１０の斜視図である。図４は、便器本体１０の上面図である。上面部１６の後方側には、下向きに凹んだ凹部２２が形成されている。凹部２２は特に、水道管などの給水源や洗浄水タンク（いずれも不図示）から便鉢１４に洗浄水を供給するための通水路４４を避けた位置に形成されている。また、凹部２２は、空洞部４６の上方を避けた位置に形成される。逆にいうと、空洞部４６は、凹部２２の下方を避けた位置に形成される。本実施の形態では、凹部２２は便鉢１４の後端部の上方に設けられ、凹部２２の下方すなわち凹部２２と便鉢１４との間には空洞部４６は存在しない。より具体的には、凹部２２の平坦な底面２８（後述）と便鉢１４との間には空洞部４６は存在しない。 FIG. 3 is a perspective view of the toilet body 10. FIG. FIG. 4 is a top view of the toilet body 10. FIG. A recess 22 recessed downward is formed on the rear side of the upper surface portion 16 . The concave portion 22 is particularly formed at a position avoiding a water passage 44 for supplying flush water to the toilet bowl 14 from a water supply source such as a water pipe or a flush water tank (neither of which is shown). Further, the concave portion 22 is formed at a position avoiding the upper side of the hollow portion 46 . Conversely, the hollow portion 46 is formed at a position avoiding the lower portion of the concave portion 22 . In the present embodiment, recess 22 is provided above the rear end of toilet bowl 14 , and cavity 46 does not exist below recess 22 , that is, between recess 22 and toilet bowl 14 . More specifically, no cavity 46 exists between the flat bottom surface 28 (described later) of the recess 22 and the toilet bowl 14 .

凹部２２は、便鉢１４の前方や側方の上面部１６の部分よりも下に凹んでいる。凹部２２は、後述の突出部１２ａが収容されるべく、突出部１２ａよりも大きく形成される。凹部２２は、本実施の形態では、開口部４０に沿うように延在している。すなわち、凹部２２は、平面視において、開口部４０に沿って僅かに湾曲している。また凹部２２は、本実施の形態では、その前方側が開口部４０に臨むように形成されている。すなわち、凹部２２は、開口部４０に連通している。凹部２２の周面のうちの前面全体が開口しているともいえる。また凹部２２は、本実施の形態では、正面視において、逆台形状を有する。 The recessed portion 22 is recessed below the portion of the upper surface portion 16 on the front and sides of the toilet bowl 14 . The concave portion 22 is formed larger than the projecting portion 12a so as to accommodate the projecting portion 12a, which will be described later. Recess 22 extends along opening 40 in the present embodiment. That is, the recess 22 is slightly curved along the opening 40 in plan view. Further, in the present embodiment, recess 22 is formed so that its front side faces opening 40 . That is, the recess 22 communicates with the opening 40 . It can be said that the entire front surface of the peripheral surface of the recess 22 is open. Further, in the present embodiment, recessed portion 22 has an inverted trapezoidal shape when viewed from the front.

凹部２２は、第１側面（右側面）２４と、第２側面（左側面）２６と、底面２８と、背面３０と、を有する。底面２８は、平坦で、左右方向に長い形状を有する。底面２８は、例えばその左右方向の長さが、便器排水路１８の左右方向の幅よりも長くなるよう形成されてもよい。また底面２８は、例えばその左右方向の長さが、開口部４０の左右方向の最大幅の１／２倍より長くなるよう形成されてもよい。 The recess 22 has a first side (right side) 24 , a second side (left side) 26 , a bottom surface 28 and a back surface 30 . The bottom surface 28 is flat and has a shape elongated in the left-right direction. The bottom surface 28 may be formed, for example, so that its length in the left-right direction is longer than the width in the left-right direction of the toilet drainage channel 18 . The bottom surface 28 may be formed, for example, so that its length in the left-right direction is longer than half the maximum width of the opening 40 in the left-right direction.

第１側面２４および第２側面２６は、左右方向に互いに離間して設けられ、下側となるほど互いに近づくように傾斜する。第１側面２４および第２側面２６は、平坦で、比較的緩やかな傾斜面となるよう形成される。好ましくは、第１側面２４および第２側面２６は、水平面とのなす角が４５°以下になるよう形成される。本実施の形態では、底面２８は水平面と略平行であるため、第１側面２４および第２側面２６は、底面２８とのなす角が４５°以下になるよう形成される。 The first side surface 24 and the second side surface 26 are spaced apart from each other in the left-right direction, and are inclined toward each other toward the bottom. The first side surface 24 and the second side surface 26 are formed to be flat and relatively gently sloping surfaces. Preferably, the first side surface 24 and the second side surface 26 are formed so that the angle between them and the horizontal plane is 45° or less. In this embodiment, since the bottom surface 28 is substantially parallel to the horizontal plane, the first side surface 24 and the second side surface 26 are formed so that the angle between the bottom surface 28 and the bottom surface 28 is 45° or less.

背面３０は、水平面とのなす角が１０°以上９０°以下になるよう形成される。本実施の形態では、上述のように底面２８は水平面と略平行であるため、背面３０は、底面２８とのなす角が１０°以上９０°以下になるよう形成される。本実施の形態では、背面３０は、底面２８と実質的に直交するよう形成される。 The rear surface 30 is formed to form an angle of 10° or more and 90° or less with a horizontal plane. In the present embodiment, since the bottom surface 28 is substantially parallel to the horizontal plane as described above, the back surface 30 is formed so that the angle between the bottom surface 28 and the bottom surface 28 is 10° or more and 90° or less. In this embodiment, back surface 30 is formed substantially perpendicular to bottom surface 28 .

また、背面３０は、開口部４０の後端部をオフセットさせた形状を有する。具体的には、背面３０は、後方側に凸形状となるよう湾曲している。ここで、セラミック材料から便器本体１０を形成する場合、上面部１６等に空洞部４６を作るために余剰のセラミック材料を排泥する。本実施の形態では、便器本体１０の後ろ側を持ち上げて前側から余剰のセラミック材料を排泥する。このとき、上述のように背面３０は後ろ側に凸形状となるよう湾曲しているため、背面３０の後方にセラミック材料が残らない。 Further, the rear surface 30 has a shape in which the rear end portion of the opening 40 is offset. Specifically, the rear surface 30 is curved to form a convex shape toward the rear side. Here, when forming the toilet body 10 from a ceramic material, excess ceramic material is drained in order to form the cavity 46 in the upper surface 16 or the like. In this embodiment, the rear side of the toilet bowl body 10 is lifted and excess ceramic material is discharged from the front side. At this time, since the rear surface 30 is curved so as to form a convex shape to the rear side as described above, no ceramic material remains behind the rear surface 30 .

図５（ａ）、（ｂ）は、機能部１２を下方から見た斜視図である。水洗大便器１００は、細長い弾性部材３２をさらに備える。図５（ａ）は弾性部材３２が機能部１２に取り付けられた状態を示し、図５（ｂ）は弾性部材３２が取り外された状態を示す。機能部１２は、ベースプレート４２をさらに含む。ベースプレート４２は、上面部１６に載置され、局部洗浄装置３４、乾燥装置３６、および脱臭装置３８を支持する。 5A and 5B are perspective views of the functional portion 12 as seen from below. The flush toilet 100 further comprises an elongated elastic member 32 . FIG. 5(a) shows a state in which the elastic member 32 is attached to the functional portion 12, and FIG. 5(b) shows a state in which the elastic member 32 is removed. Functional portion 12 further includes a base plate 42 . A base plate 42 is placed on the top surface 16 and supports the private cleaning device 34 , the drying device 36 and the deodorizing device 38 .

機能部１２は、その前方中央部に、下向きに突出した突出部１２ａを有する。この突出部は、下向きに凹んだベースプレート４２のベース凹部４２ａと、そのベース凹部４２ａに収容された局部洗浄装置３４のノズル３４ａの先端部と、乾燥装置３６の温風吹出口３６ａと、脱臭装置３８の脱臭吸込口３８ａおよび脱臭吐出口３８ｂと、それらの後方に位置する脱臭カートリッジ３８ｃとによって構成される。 The functional part 12 has a protruding part 12a protruding downward at its front central part. The projecting portion includes a base recess 42a of a base plate 42 recessed downward, a tip of a nozzle 34a of a private cleaning device 34 accommodated in the base recess 42a, a hot air outlet 36a of a drying device 36, and a deodorizing device 38. , a deodorizing inlet 38a, a deodorizing outlet 38b, and a deodorizing cartridge 38c located behind them.

ベース凹部４２ａの下面を含むベースプレート４２の下面４２ｂには、概ね左右方向に延びる溝４２ｃが形成されている。溝４２ｃには、弾性部材３２が例えば両面テープにより着脱可能に取り付けられる。弾性部材３２は、例えばゴムにより形成される。溝４２ｃは、機能部１２の前縁よりも奥側（すなわち後方側）に形成される。したがって、そこに取り付けられる弾性部材３２も、機能部１２の前縁よりも奥側に設けられる。つまり、弾性部材３２は、機能部１２の前縁よりも前側に突出しないように設けられる。 A groove 42c extending generally in the horizontal direction is formed in the lower surface 42b of the base plate 42 including the lower surface of the base recess 42a. The elastic member 32 is detachably attached to the groove 42c by, for example, double-sided tape. The elastic member 32 is made of rubber, for example. The groove 42c is formed on the back side (that is, on the rear side) of the front edge of the functional portion 12. As shown in FIG. Therefore, the elastic member 32 attached there is also provided behind the front edge of the functional portion 12 . That is, the elastic member 32 is provided so as not to protrude forward beyond the front edge of the functional portion 12 .

図６（ａ）、（ｂ）は、凹部２２とその周辺を示す正面図である。図７（ａ）、（ｂ）は、凹部２２とその周辺を示す断面図である。図６（ａ）、図７（ａ）は、機能部１２が下降位置にあるときを示し、図６（ｂ）、図７（ｂ）は、機能部１２が上昇位置にあるときを示す。 6A and 6B are front views showing the recess 22 and its periphery. 7A and 7B are cross-sectional views showing the recess 22 and its surroundings. 6(a) and 7(a) show the functional portion 12 at the lowered position, and FIGS. 6(b) and 7(b) show the functional portion 12 at the raised position.

機能部１２が下降位置にあるとき、その突出部１２ａは凹部２２内に位置する。具体的には本実施の形態では、脱臭カートリッジ３８ｃが収容されている突出部１２ａの部分が、すなわち突出部１２ａの後方側が凹部２２内に位置する。 When the functional part 12 is in the lowered position, its protruding part 12a is positioned within the recess 22. As shown in FIG. Specifically, in the present embodiment, the portion of the protruding portion 12a in which the deodorizing cartridge 38c is housed, that is, the rear side of the protruding portion 12a is positioned within the recess 22. As shown in FIG.

図６（ａ）、図７（ａ）に示すように、機能部１２が下降位置にあるとき、左右方向における機能部１２と凹部２２との２つの隙間の部分には、機能部１２と凹部２２とに当接するよう弾性部材３２が設けられている。具体的には、弾性部材３２は、凹部２２の第１側面２４と、第１側面２４と左右方向で対向する突出部１２ａの第１側面（右側面）１２ｂとに当接する。同様に、弾性部材３２は、凹部２２の第２側面２６と、第２側面２６と左右方向で対向する突出部１２ａの第２側面（左側面）１２ｃとに当接する。 As shown in FIGS. 6(a) and 7(a), when the functional portion 12 is in the lowered position, the gap between the functional portion 12 and the recessed portion 22 in the left-right direction includes the functional portion 12 and the recessed portion. An elastic member 32 is provided so as to abut against 22 . Specifically, the elastic member 32 contacts the first side surface 24 of the recess 22 and the first side surface (right side surface) 12b of the projecting portion 12a facing the first side surface 24 in the left-right direction. Similarly, the elastic member 32 contacts the second side surface 26 of the recess 22 and the second side surface (left side surface) 12c of the projecting portion 12a facing the second side surface 26 in the left-right direction.

本実施の形態ではさらに、左右方向における機能部１２と凹部２２との２つの隙間の部分に設けられる弾性部材３２は、上下方向における機能部１２と凹部２２との隙間を通って連なっている。具体的には、凹部２２第１側面２４と突出部１２ａの第１側面１２ｂとの間の弾性部材３２と、凹部２２の第２側面２６と突出部１２ａの第２側面１２ｃとの間の弾性部材３２とは、凹部２２の底面２８と、底面２８と上下方向で対向する突出部１２ａの下面１２ｄとの間の隙間を通って連なっている。弾性部材３２は特に、凹部２２の底面２８と、突出部１２ａの下面１２ｄとに当接する。つまり、弾性部材３２は、正面視において、突出部１２ａと凹部２２との隙間を埋めるように設けられる。また、本実施の形態では、弾性部材３２は、凹部２２の左右方向外側の上面部１６の部分まで延びている。 Further, in the present embodiment, the elastic member 32 provided in the gap between the functional portion 12 and the recess 22 in the left-right direction is connected through the gap between the functional portion 12 and the recess 22 in the vertical direction.
