The flush water is supplied to the upper inner surface of the toilet bowl through the water conduit from the water outlet, and the inner surface of the toilet bowl is washed by the wash water flowing down while turning from the water conduit. In a Western-style toilet, the front part of the toilet bowl has a substantially arc shape in plan view, and the radius of curvature of the front part of the toilet bowl is equal to the two side parts of the toilet bowl connected to both ends of the front part. It is smaller than the radius of curvature in the longitudinal direction, and in the foremost part of the front part of the toilet bowl part, the water conduit consists of a shelf part and an upright part rising from the outer periphery of the shelf part. In the water conduit, from the water outlet to the vicinity of the foremost part, the shelf, the raised portion, and the upper end of the raised portion are inward of the toilet bowl. It is composed of a shelf return part of output is characterized in.

請求項４の洋風便器は、請求項３において、該棚返し部の下面は、導水路長手方向において略同一高さであることを特徴とするものである。 The western style toilet of claim 4 is characterized in that, in claim 3, the bottom surface of the shelf turning portion has substantially the same height in the longitudinal direction of the conduit .

請求項５の洋風便器は、請求項３において、該棚返し部の下面は、最前部近傍において便鉢部前側ほど低くなっていることを特徴とするものである。 The western style toilet of claim 5 is characterized in that, in claim 3, the lower surface of the shelf return portion is lower toward the front of the toilet bowl in the vicinity of the foremost portion .

請求項６の洋風便器は、請求項１ないし５のいずれか１項において、前記便鉢部の２つの側部のうち該吐水口が形成されていない側の側部に設けられた導水路の少なくとも一部は、前記棚部、立上部及び棚返し部とで構成されていることを特徴とするものである。
請求項７の洋風便器は、請求項１ないし６のいずれか１項において、前記便鉢部の側部は略直線状に前後方向に延在していることを特徴とするものである。 A western style toilet of claim 6 is the water channel provided in any one of claims 1 to 5 on a side portion of the two side portions of the toilet bowl portion on which the spout is not formed. At least one part is comprised by the said shelf part, an upright part, and a shelf return part, It is characterized by the above- mentioned.
A western style toilet of claim 7 is characterized in that, in any one of claims 1 to 6, a side portion of the stool portion extends in a front-rear direction in a substantially linear shape.

便鉢部の上部内面周りに導水路が形成された洋風便器にあっては、導水路の吐水口付近において水量が最も多いため、当該箇所付近で洗浄水が洋風便器の外側に飛び出し易い。また、導水路は該吐水口から前方に延在し、便鉢部の最前部よりも手前において長手方向の曲率が小さくなるため、当該箇所において大きな遠心力が加わって、洗浄水が洋風便器の外側に飛び出し易い。   In a Western style toilet with a water conduit formed around the upper inner surface of the toilet bowl, the amount of water is the largest in the vicinity of the water outlet of the water conduit, so that the wash water tends to jump out of the Western style toilet near that location. Further, the water conduit extends forward from the spout, and since the curvature in the longitudinal direction becomes smaller in front of the front part of the toilet bowl, a large centrifugal force is applied at the location, so that the washing water flows into the Western-style toilet. Easy to jump out.

本発明の洋風便器にあっては、該導水路のうち該吐水口から該最前部近傍までは、棚部と、該棚部の外周から立上する立上部と、該立上部の上端から便鉢部の内方に突出する棚返し部とで構成されている。このため、洗浄水が洋風便器の外側に飛び出ることが確実に防止される。   In the western style toilet of the present invention, from the water outlet to the vicinity of the foremost part of the water conduit, a shelf, an upright rising from the outer periphery of the shelf, and a stool from an upper end of the upright It is comprised with the shelf return part which protrudes inward of a bowl part. This reliably prevents the washing water from jumping out of the western-style toilet.

また、便鉢部の最前部にあっては、該導水路は、棚部と、該棚部の外周から立上する立上部とからなり、棚返し部が形成されていない。このため、洋風便器の上方から棚部及び立上部を目視しながら清掃することができ、清掃が容易である。   Moreover, in the foremost part of a toilet bowl part, this water conduit consists of a shelf part and the upright part which stands | starts up from the outer periphery of this shelf part, and the shelf return part is not formed. For this reason, it can clean while visually observing a shelf part and an upright part from the upper part of a Western style toilet bowl, and cleaning is easy.

この便鉢部の２つの側部のうち吐水口が形成されていない側の側部に設けられた導水路の少なくとも一部も、前記棚部、立上部及び棚返し部とで構成されている場合、該棚返し部の上面に便座の裏面が当接することにより、便座の安定感がよくなる。   At least a part of the water conduit provided in the side portion where the water outlet is not formed among the two side portions of the toilet bowl portion is also configured by the shelf portion, the upright portion, and the shelf return portion. In this case, the back surface of the toilet seat comes into contact with the upper surface of the shelf return portion, so that the stability of the toilet seat improves.

この便鉢部の側部が略直線状に前後方向に延在している場合、導水路のうち該便鉢部側部よりも前側において長手方向のカーブが急になり、このカーブが急になる付近において洗浄水が洋風便器の外側に飛び出し易い。しかし、上記の通り吐水口から便鉢部最前部近傍にわたって棚返し部が形成されており、該カーブが急になる部分よりも前側まで棚返し部が形成されているため、導水路から洗浄水が洋風便器の外側に飛び出ることが確実に防止される。   When the side portion of the toilet bowl portion extends in the front-rear direction in a substantially straight line, the longitudinal curve becomes steep on the front side of the toilet bowl side portion of the water conduit, and this curve suddenly In the vicinity, the washing water tends to jump out of the Western-style toilet. However, as described above, the shelf turning part is formed from the outlet to the vicinity of the foremost part of the toilet bowl part, and the shelf turning part is formed to the front side rather than the part where the curve is steep, so that the washing water from the water conduit Is reliably prevented from popping out of the Western-style toilet.

この便鉢部の最前部近傍における前記立上部の内周面の平面視形状が略円弧形である場合、洗浄水が当該箇所を滑らかに走行することができ、導水路から洗浄水が洋風便器の外側に飛び出ることが確実に防止される。   When the plan view shape of the inner peripheral surface of the upright portion in the vicinity of the foremost portion of the toilet bowl portion is a substantially arc shape, the washing water can smoothly travel in the part, and the washing water from the water conduit is Western-style. Jumping out of the toilet is reliably prevented.

この棚返し部の下面が導水路長手方向において略同一高さである場合、導水路内の清掃が容易である。   When the bottom surface of the shelf return part has substantially the same height in the longitudinal direction of the conduit, cleaning of the conduit is easy.

この棚返し部の下面が最前部近傍において便鉢部前側ほど低くなっている場合、該最前部近傍において該棚返し部の下面によって導水路内の洗浄水が下向きに跳ね返されるため、導水路から洗浄水が洋風便器の外側に飛び出ることが確実に防止される。   When the lower surface of the shelf return part is lower toward the front of the toilet bowl in the vicinity of the foremost part, the wash water in the water conduit is rebounded downward by the lower surface of the shelf return part in the vicinity of the foremost part. The washing water is surely prevented from jumping out of the western style toilet.

以下、図面を参照して本発明の実施の形態を詳細に説明する。第１図は実施の形態に係る洋風便器の平面図、第２図は第１図のII−II線に沿う断面図、第３図は第１図のIII−III線に沿う断面図、第４図は第１図のIV−IV線に沿う断面図、第５図は第１図のＶ−Ｖ線に沿う断面図、第６図は第１図の洋風便器の部分的な斜視図である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a plan view of a western style toilet according to the embodiment, FIG. 2 is a sectional view taken along line II-II in FIG. 1, FIG. 3 is a sectional view taken along line III-III in FIG. 4 is a sectional view taken along line IV-IV in FIG. 1, FIG. 5 is a sectional view taken along line V-V in FIG. 1, and FIG. 6 is a partial perspective view of the western-style toilet of FIG. is there.

第１図の通り、洋風便器１の前部上面に便鉢部２が形成されている。この便鉢部２の底部に開口３が形成され、該開口３の下方に図示しないトラップ部が連なっている。該洋風便器１の上面のうち該便鉢部２よりも後方に、便座及び便蓋を取り付けるための挿通孔４、４が設けられている。洋風便器１の上面の挿通孔４、４よりも後方は、図示しないロータンクを載置する載置部５となっている。該便鉢部２の右側（第１図の上側）の側部ｓ１及び左側（第１図の下側）の側部ｓ２は略直線状に前後方向に延在しており、これら側部ｓ１、ｓ２より前側の前部ｆ及びこれら側部ｓ１、ｓ２より後ろ側の後部ｒは略円弧状に延在している。 As shown in FIG. 1, a toilet bowl 2 is formed on the upper surface of the front part of the western-style toilet 1. An opening 3 is formed at the bottom of the stool part 2, and a trap part (not shown) is continuous below the opening 3. Insertion holes 4 and 4 for attaching a toilet seat and a toilet lid are provided on the upper surface of the Western-style toilet 1 behind the toilet bowl 2. Behind the insertion holes 4 and 4 on the upper surface of the Western-style toilet 1, there is a mounting portion 5 for mounting a low tank (not shown).該便bowl portion side s 2 of the second right side s 1 and left (upper Figure 1) (the lower side of FIG. 1) extends in the longitudinal direction in a substantially linear shape, these side rear r parts s 1, s 2 from the front side of the front f and their side s 1, s 2 from the rear side extends in a substantially arcuate shape.

便鉢２の上部内面周りに導水路１０が形成されている。第１図及び第６図の通り、該導水路１０のうち便鉢２後部側の右寄りの位置に、該導水路１０に洗浄水を供給するための吐水口１１が形成されている。   A water conduit 10 is formed around the upper inner surface of the toilet bowl 2. As shown in FIGS. 1 and 6, a spout 11 for supplying wash water to the water conduit 10 is formed at a position on the right side of the rear portion of the toilet bowl 2 in the water conduit 10.

該導水路１０のうち、吐水口１１から便鉢２の最前部の近傍までは、該導水路１０は上向きの棚部１０ａと、該棚部１０ａの外周から立上する立上部１０ｂと、該立上部１０ｂの上端から便鉢２の内方に突出する棚返し部１０ｃとで構成されている。   Of the water conduit 10, from the water outlet 11 to the vicinity of the foremost portion of the toilet bowl 2, the water conduit 10 has an upward shelf 10a, an upright portion 10b rising from the outer periphery of the shelf 10a, It is comprised by the shelf return part 10c which protrudes inward of the toilet bowl 2 from the upper end of the upright part 10b.

該導水路１０のうち、該便鉢２の最前部及びその下流の前部ｆ、側部ｓ２及び後部ｒにあっては、該導水路１０は該棚部１０ａと、該立上部１０ｂとで構成されている。 Among the water conduits 10, in the foremost part of the toilet bowl 2 and the front part f, the side part s 2, and the rear part r downstream thereof, the water conduit 10 includes the shelf part 10 a, the raised part 10 b, It consists of

棚部１０ａは、短手方向に水平であるか、または便鉢の内側ほど低くなっている。また、本実施の形態では、棚部１０ａは長手方向の高さが同一となっている。   The shelf 10a is horizontal in the lateral direction or is lowered toward the inside of the toilet bowl. Moreover, in this Embodiment, the height of the longitudinal direction is the same as the shelf part 10a.

このように構成された洋風便器１において、図示しないフラッシュハンドルやフラッシュスイッチが操作されると、図示しないロータンクからディストリビュータを介して洗浄水が洋風便器１の後部内に供給され、さらに吐水口１１から導水路１０内に供給される。該吐水口１１から導水路１０内に供給された洗浄水は、該導水路１０の右側の側部ｓ１、前部ｆ、左側の側部ｓ２及び後部ｒの順で、棚部１０ａの上側を走行する。これにより、便鉢２の上部内面周りに洗浄水が行き渡り、該導水路１０から旋回しながら便鉢２の内面を流下する。この流下する洗浄水によって便鉢２の内面が洗浄される。 In the Western-style toilet 1 configured as described above, when a flush handle or a flush switch (not shown) is operated, wash water is supplied from a low tank (not shown) via the distributor into the rear portion of the Western-style toilet 1 and further from the spout 11. It is supplied into the water conduit 10. The wash water supplied from the water outlet 11 into the water conduit 10 is in the order of the right side s 1 , the front f, the left side s 2, and the rear r of the water conduit 10. Drive on the upper side. Thereby, the washing water spreads around the upper inner surface of the toilet bowl 2 and flows down the inner surface of the toilet bowl 2 while turning from the water conduit 10. The inner surface of the toilet bowl 2 is washed by the flowing washing water.

ここで、洗浄水が吐水口１１から導水路１０内に供給される際、洗浄水の流れが乱れる。また、導水路１０内のうち吐水口１１付近が最も水量が多い。このため、導水路１０の吐水口１１近傍において、洗浄水は立上部１０ｂに沿って上方に流れ易い。しかしながら、当該箇所には棚返し部１０ｃが設けられているため、上方に流れる洗浄水は該棚返し部１０ｃに跳ね返されることになり、洗浄水が洋風便器１の外側に飛び出ることが防止される。   Here, when the wash water is supplied from the water outlet 11 into the water conduit 10, the flow of the wash water is disturbed. Further, the vicinity of the spout 11 in the water conduit 10 has the largest amount of water. For this reason, in the vicinity of the water discharge port 11 of the water conduit 10, the wash water easily flows upward along the upright portion 10b. However, since the shelf return part 10c is provided in the said location, the wash water which flows upward will be bounced back to this shelf return part 10c, and it will be prevented that the wash water jumps out of the western style toilet 1. .

また、洗浄水は略直線状の側部ｓ１内を流れた後、略円弧状の前部ｆを流れる。この前部ｆは側部ｓ１よりも長手方向の曲率半径が小さいため、該前部ｆの側部ｓ１近傍において、洗浄水に加わる遠心力が大きくなる。この遠心力のため、洗浄水は立上部１０ｂに沿って上方に流れるが、該前部ｆの側部ｓ１近傍の位置にも棚返し部１０ｃが設けられているため、該棚返し部１０ｃによって洗浄水が下方に跳ね返されることになり、これにより洗浄水が洋風便器１の外側に飛び出ることが防止される。 Further, the wash water after flowing through substantially linear in side s 1, through a substantially arcuate front f. Since this front f is the longitudinal direction of the radius of curvature is smaller than the side s 1, at the side s 1 near the front portion f, the centrifugal force exerted on the washing water increases. Therefore the centrifugal force, but the wash water flows upward along the upright portion 10b, since the shelf return part 10c in the position of the side s 1 near the front portion f is provided, shelf return part 10c As a result, the wash water is rebounded downward, thereby preventing the wash water from jumping out of the western-style toilet 1.

該洗浄水は前部ｆ内を略円弧状に滑らかに走行した後、側部ｓ２及び後部ｒ内を走行する。 The washing water travels smoothly in the front part f in a substantially arc shape, and then travels in the side part s 2 and the rear part r.

なお、導水路１０内を走行する過程において、洗浄水は徐々に導水路１０内から便鉢２の下方に流下するため、導水路１０内の水量は下流に行くに従って減量し、水勢が弱くなる。このため、便鉢２の最前部及びその下流に棚返し部１０ｃを設けなくても、洗浄水が立上部１０ｂに沿って上方に流れて洋風便器１の外側に飛び出ることはない。   In the process of traveling in the water conduit 10, the washing water gradually flows down from the water conduit 10 to the lower part of the toilet bowl 2, so that the amount of water in the water conduit 10 decreases as it goes downstream, and the water strength becomes weaker. . For this reason, even if it does not provide the shelf return part 10c in the forefront part of the toilet bowl 2 and its downstream, a wash water does not flow upward along the upright part 10b, and jumps out of the western-style toilet 1 outside.

本実施の形態の洋風便器１にあっては、導水路１０のうち便鉢２の最前部近傍よりも下流側に棚返し部１０ｃが設けられていないため、清掃時に当該部分の棚部１０ａ及び立上部１０ｂを上方から目視しながら清掃することができ、清掃が容易である。   In the Western-style toilet 1 of this Embodiment, since the shelf return part 10c is not provided in the downstream rather than the foremost part vicinity of the toilet bowl 2 in the water conduit 10, the shelf part 10a of the said part at the time of cleaning, The upright portion 10b can be cleaned while visually checking from above, and cleaning is easy.

上記実施の形態では棚返し部１０ｃを中実の板状としたが、第７、８図のように中空にしてもよい。   In the above embodiment, the shelf turning portion 10c is a solid plate, but it may be hollow as shown in FIGS.

第７図は棚返し部１０ｄを中空にした導水路１０Ａの縦断面図、第８図は該導水路１０Ａが形成された洋風便器１Ａの縦断面図である。   FIG. 7 is a longitudinal sectional view of a water conduit 10A in which the shelf turning portion 10d is hollow, and FIG. 8 is a longitudinal sectional view of a Western-style toilet 1A in which the water conduit 10A is formed.

なお、第７、８図の洋風便器１Ａにあっては、棚返し部１０ｄの下面１０ｕは長手方向にわたり同一高さになっている。このため、導水路１０Ａの清掃が容易である。   In addition, in the western style toilet 1A of FIGS. 7 and 8, the lower surface 10u of the shelf turning portion 10d has the same height in the longitudinal direction. For this reason, cleaning of the water conduit 10A is easy.

但し、第９図の通り、棚返し部１０ｄの下面１０ｕは便鉢２の最前部近傍において便鉢２の前側ほど低くなっていてもよい。この場合、棚返し部１０ｄの下流側近傍において該棚返し部１０ｄの下面１０ｕによって導水路１０Ａ内の洗浄水が下向きに跳ね返されるため、棚返し部１０ｄの下流端よりも下流側において導水路１０Ａから洗浄水が洋風便器１Ａの外側に飛び出ることが確実に防止される。   However, as shown in FIG. 9, the lower surface 10 u of the shelf return portion 10 d may be lowered toward the front side of the toilet bowl 2 in the vicinity of the foremost portion of the toilet bowl 2. In this case, since the wash water in the water conduit 10A is rebounded downward by the lower surface 10u of the shelf return part 10d in the vicinity of the downstream side of the shelf return part 10d, the water guide path 10A is provided downstream of the downstream end of the shelf return part 10d. The washing water is reliably prevented from jumping out of the western style toilet 1A.

なお、第１０図の通り、棚返し部１０ｄの下面１０ｕを棚返し部１０ｄの下流側近傍において便鉢２の前側ほど低くし、かつ該棚返し部１０ｄの最も下流側に、下面１０ｕの高さが同一である同一高さ部分１０ｅを設けてもよい。この場合、同一高さ部１０ｅにおいて洗浄水が整流となり、洗浄水が便鉢２の外側に飛び出ることが防止される。   As shown in FIG. 10, the lower surface 10u of the shelf turning portion 10d is lowered toward the front side of the toilet bowl 2 in the vicinity of the downstream side of the shelf turning portion 10d, and the height of the lower surface 10u is set on the most downstream side of the shelf turning portion 10d. The same height portion 10e having the same length may be provided. In this case, the washing water is rectified at the same height portion 10e, and the washing water is prevented from jumping out of the toilet bowl 2.

上記実施の形態では導水路の側部ｓ２に棚返し部が設けられていないが、該側部ｓ２に棚返し部が設けられてもよい。 In the above embodiments is not shelf-back portion is provided on the side s 2 of the water conduit, it may be shelf-back portion is provided on the side portion s 2.

第１１図は導水路の側部ｓ２に棚返し部が設けられた洋風便器の平面図、第１２図は第１１図のVII−VII線に沿う断面図、第１３図は第１１図のVIIIａ−VIIIａ線に沿う断面図、VIIIｂ−VIIIｂ線に沿う断面図である。 FIG. 11 is a plan view of a Western style toilet having a shelf return portion provided on the side s 2 of the water conduit, FIG. 12 is a sectional view taken along line VII-VII in FIG. 11, and FIG. It is sectional drawing in alignment with a VIIIa-VIIIa line, and sectional drawing in alignment with a VIIIb-VIIIb line.

第１１〜１３図の洋風便器１Ａは、導水路１０の側部ｓ２にも棚返し部１０ｃを設けたことの他は第１〜６図の洋風便器１と同一であり、第１〜６図と同一符号は同一部分を示している。この洋風便器１Ａは側部ｓ１、ｓ２の両方に棚返し部１０ｃが設けられているため、該棚返し部１０ｃの上面に便座の裏面が当接することにより、便座の安定感がよくなる。 Toilet stool 1A of the 11-13 figure, other also on the side s 2 of the water conduit 10 provided with the rack return part 10c is the same as toilet stool 1 of the sixth view, first to sixth The same reference numerals as those in the figure denote the same parts.

上記実施の形態は本発明の一例であり、本発明は上記実施の形態に限定されない。例えば、棚部のレベルは長手方向にわたり略水平であるが、長手方向の下流側ほど低くなっていてもよい。この場合、吐水口から導水路内に供給された洗浄水を導水路の長手方向下流側まで十分に供給することができる。なお、このように棚部のレベルを下流側ほど低くすると、棚部のレベルが同一の場合と比べて導水路内の下流側において洗浄水の水勢が強くなるが、該下流側において該棚部と便鉢の上縁部との高低差が大きくなるため、洗浄水が立上部を上って洋風便器の外側に飛び出ることは無い。   The above embodiment is an example of the present invention, and the present invention is not limited to the above embodiment. For example, the level of the shelf is substantially horizontal over the longitudinal direction, but may be lower toward the downstream side in the longitudinal direction. In this case, the washing water supplied from the water outlet into the water conduit can be sufficiently supplied to the downstream side in the longitudinal direction of the water conduit. In addition, when the level of the shelf portion is lowered as the downstream side in this way, the water flow of the washing water becomes stronger on the downstream side in the water conduit than in the case where the level of the shelf portion is the same, but the shelf portion on the downstream side. Since the difference in height between the stool and the upper edge of the toilet bowl becomes large, the washing water does not jump up to the outside of the western-style toilet.
