Description

本発明は、便器本体の後側上面に機能部を装着したベース部を固定した水洗式便器に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush toilet in which a base portion having a functional portion attached to the rear upper surface of a toilet body is fixed.

従来、水洗式便器として、例えば特許文献１に記載のように便鉢を設けた便器本体の後側上面に固定プレートをボルトとナットで固定したものが知られている。固定プレートを便器本体に固定する際、便器本体の上面から固定プレートの孔部と便器本体のネジ穴にボルトを貫通して便器本体の下面に突出させてナットで締め付け固定していた。 BACKGROUND ART Conventionally, as a flush toilet, there is known a flush toilet in which a fixing plate is fixed with bolts and nuts to the rear upper surface of a toilet body provided with a toilet bowl, as described in Patent Document 1, for example. When fixing the fixing plate to the toilet bowl body, bolts are passed through the holes of the fixing plate and the screw holes of the toilet bowl body from the upper surface of the toilet bowl body, protruding from the lower surface of the toilet bowl body, and then tightened with nuts.

そして、固定プレート上で便器本体の前方から機能部や便座を含む便座ボックスを後方にスライドさせて、便座ボックスの下面に形成した凹所を固定プレートに嵌合させ、凹所の両側部の係合凹部を固定プレートの両側部に設けた凸条と係合させて固定している。便座ボックスは便器本体の平坦な上面に固定した固定プレート上に設置されている。便座ボックスは陶器製の便器本体の凹凸や傾きの影響を受け易いため固定プレートと機能部の凹所の間にクリヤランスを設けている。 Then, the toilet seat box including the functional part and the toilet seat is slid rearward from the front of the toilet body on the fixing plate, and the recess formed in the lower surface of the toilet seat box is fitted to the fixing plate, and both sides of the recess are engaged. The mating recesses are fixed by engaging with ridges provided on both sides of the fixing plate. The toilet seat box is mounted on a fixed plate fixed to the flat upper surface of the toilet bowl body. A clearance is provided between the fixing plate and the recess of the functional part because the toilet seat box is easily affected by the unevenness and inclination of the ceramic toilet bowl body.

しかしながら、機能部を内蔵した便座ボックスは平坦な便器本体と固定プレートの上部に設置するため便座ボックスの高さが大きくなり、使用者に圧迫感を与えるおそれがあった。 However, since the toilet seat box with built-in functional parts is installed above the flat toilet bowl body and the fixing plate, the height of the toilet seat box increases, and there is a possibility that the user may feel oppressed.

本発明は、このような課題に鑑みてなされたものであって、高さを低く抑えてコンパクトに形成できる水洗式便器を提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a flush toilet that can be made compact by keeping the height low.

本発明による水洗式便器は、前部に形成された便鉢、後部上面の周縁部に設けられた周壁部、および該周壁部の内側に形成され前記周壁部に対して下方に向けて凹んだ凹部、を有する便器本体と、前記凹部に配置可能な機能部を備えたベース部と、を備え、前記便器本体と前記ベース部とは受け部を介して支持され、前記受け部は、前記周壁部よりも内側かつ前記周壁部の上面より下方で前記便器本体に配置されていることを特徴とする。
本発明によれば、機能部を備えたベース部の支持点を低い位置に設定することができ、結果として、水洗式便器の高さを低く抑えてコンパクトに構成することができる。 The flush toilet according to the present invention comprises a toilet bowl formed in the front portion, a peripheral wall portion provided on the peripheral edge portion of the rear upper surface, and a peripheral wall portion formed inside the peripheral wall portion and recessed downward with respect to the peripheral wall portion. a toilet bowl body having a recess; and a base portion having a functional portion that can be arranged in the recess, wherein the toilet bowl body and the base portion are supported via a receiving portion, and the receiving portion is attached to the peripheral wall. is arranged in the toilet bowl body inside the portion and below the upper surface of the peripheral wall portion.
ADVANTAGE OF THE INVENTION According to this invention, the support point of the base part provided with the function part can be set at a low position, and as a result, the height of the flush toilet can be suppressed low and it can be comprised compactly.

また、前記凹部が、前記便鉢の上面よりも低い領域に形成されており、前記受け部が、前記凹部内で前記便器本体に支持されていてもよい。
本発明によれば、凹部内で受け部を便器本体に支持することにより、ベース部の支持点をさらに低い位置に設定することができる。 Further, the recess may be formed in a region lower than the upper surface of the toilet bowl, and the receiving portion may be supported by the toilet body within the recess.
According to the present invention, the supporting point of the base portion can be set at a lower position by supporting the receiving portion on the toilet body within the recess.

また、前記ベース部は、前記機能部を設置可能に構成され、かつ、前記受け部に連結する被受け部を備えていてもよい。
本発明によれば、受け部を介してベース部を便器本体に取り付けるだけで機能部も設置されるため、施工が容易になる。 Further, the base portion may include a receiving portion that is configured to allow installation of the function portion and that is connected to the receiving portion.
According to the present invention, the functional portion can be installed simply by attaching the base portion to the toilet bowl body via the receiving portion, so construction is facilitated.

さらに、前記便器本体に前記ベース部を支持固定した状態において、前記ベース部の縁部の少なくとも一部が前記周壁部に沿って配置されていてもよい。
本発明によれば、施工が容易になる。 Furthermore, in a state in which the base portion is supported and fixed to the toilet body, at least part of the edge portion of the base portion may be arranged along the peripheral wall portion.
The present invention facilitates construction.

そして、前記凹部に、下方に向けて穴部または溝部が形成され、前記機能部が収納された前記ベース部の少なくとも一部が、前記穴部または溝部に嵌合可能に構成されていてもよい。
本発明によれば、便器本体の穴部または溝部に嵌合するベース部の内部に機能部の一部または全部が収納されているため、ベース部の上面に設置される機能部等の高さを低く設定できて圧迫感がなくコンパクトに形成できる。
また、従来は固定プレートを便器本体の上面にボルトとナットで固定する場合、便器を設置するトイレ空間が狭いと便器を下から覗き込むような姿勢で便器本体の上面に挿通したボルトにナットを締め込むため、組み付けの施工性が悪かった。しかしながら、本発明では、ベース部を穴部または溝部に嵌合可能に構成したことにより、組み付けを容易にし、施工性を向上させることができる。 A hole portion or a groove portion may be formed in the concave portion so as to extend downward, and at least a part of the base portion in which the functional portion is accommodated may be configured to be fittable in the hole portion or the groove portion. .
According to the present invention, since part or all of the functional part is housed inside the base part that fits into the hole or groove part of the toilet body, the height of the functional part, etc., installed on the upper surface of the base part can be set low and can be formed compactly without feeling oppressive.
Conventionally, when fixing the fixing plate to the upper surface of the toilet bowl with bolts and nuts, if the toilet space in which the toilet is installed is narrow, the bolts inserted through the upper surface of the toilet bowl should be attached with a nut so that the user can look into the toilet bowl from below. Because it was tightened, the workability of assembly was poor. However, in the present invention, the base portion is configured to be fittable in the hole or the groove portion, thereby facilitating assembly and improving workability.

本発明による水洗式便器によれば、便器本体の後部に設置する製品の高さを低くすることができてコンパクトに製造することができる。 According to the flush toilet bowl of the present invention, it is possible to reduce the height of the product installed in the rear part of the toilet bowl body and to manufacture it compactly.

As shown in FIG. A functional unit 3 such as a washing nozzle, a heater, and electric parts (not shown) is installed on the base plate 13 , and a shutter 21 is attached to the surface facing the toilet bowl 8 . A first projecting portion 22 that can be fitted into the first hole portion 11 and a second projecting portion 23 that can be fitted into the second hole portion 12 are formed on the lower surface of the base plate 13 so as to protrude downward. The first protruding portion 22 and the second protruding portion 23 are formed in a substantially bottomed cylindrical shape, and appropriate electric components and the like forming a part of the functional portion 3 are accommodated therein.
Therefore, in a state in which the base plate 13 is fitted in the recess 9 and the first protrusion 22 and the second protrusion 23 are fitted in the first hole 11 and the second hole 12 of the recess 9, The rest of the functional parts are installed on the upper surface of the base plate 13, but their height can be lower than that of conventional functional parts.

また、便座ユニット７において、ベースプレート１３の下面で第一突出部２２と第二突出部２３の前方には前側爪部（被受け部）２４、２５が形成されている。前側爪部２４、２５は、図６に示すように、弾性変形可能な断面略Ｌ字状で便器本体２の前側受け部１５，１６の係止開口１５ａ、１６ａにそれぞれ係合可能である。
図７及び図８において、凹部９の後方の突堤部９ａ近傍に設けた後側受け部１８にはベースプレート１３に設けた後側スライド爪部２７がスライド可能に設置されている。後側スライド爪部２７は突堤部９ａに沿って略円弧状に延びる爪部本体２７ａの中間部に爪受け部１９に係合可能な爪部２７ｂが略直角に突出して形成されている。爪部本体２７ａの一方の端部には例えば階段状の操作部２７ｃが形成され、他方の端部には弾性部材として例えばコイルばね２８が圧縮状態で他端の当接面２９との間に保持されている。また、爪部本体２７ａの下面には後側スライド爪部２７のスライド移動を規制するための係止片２７ｄが形成されている。 Further, in the toilet seat unit 7 , front claw portions (receiving portions) 24 and 25 are formed on the lower surface of the base plate 13 in front of the first projecting portion 22 and the second projecting portion 23 . As shown in FIG. 6, the front claws 24, 25 are elastically deformable and have a substantially L-shaped cross section, and can be engaged with locking openings 15a, 16a of the front receiving parts 15, 16 of the toilet body 2, respectively.
7 and 8, a rear slide claw portion 27 provided on the base plate 13 is slidably installed on a rear receiving portion 18 provided in the vicinity of the jetty portion 9a behind the recess 9. As shown in FIG. The rear slide pawl portion 27 is formed with a pawl portion 27b that can be engaged with the pawl receiving portion 19 and protrudes substantially at a right angle from an intermediate portion of a pawl portion body 27a that extends in a substantially arc shape along the jetty portion 9a. A stepped operation portion 27c, for example, is formed at one end of the claw portion main body 27a, and an elastic member, such as a coil spring 28, is formed at the other end between a contact surface 29 at the other end in a compressed state. held. A locking piece 27d for restricting the sliding movement of the rear slide claw 27 is formed on the lower surface of the claw main body 27a.

そのため、ベースプレート１３を下方に押し下げて後側スライド爪部２７の爪部２７ｂを後側受け部１８の爪受け部１９のテーパ部１９ａに沿って右方にスライドさせ、コイルばね２８を圧縮させて後側スライド爪部２７を右方に移動させて上方から下方に乗り越える。すると、コイルばね２８の付勢力で後側スライド爪部２７が左方に移動して爪部２７ｂが爪受け部１９の下側で係合し、係止片２７ｄは凹部９の係止部３０に当接して係止する。
また、後側スライド爪部２７を外すには、ベースプレート１３を持ち上げながら指で操作部２７ｃを右方にスライドさせて爪部２７ｂが爪受け部１９を乗り越えることで係止を解除できる。 Therefore, the base plate 13 is pushed downward to slide the claw portion 27b of the rear slide claw portion 27 rightward along the taper portion 19a of the claw receiving portion 19 of the rear receiving portion 18, thereby compressing the coil spring 28. The rear side slide claw part 27 is moved to the right to get over from above to below. Then, the rear slide pawl portion 27 is moved leftward by the biasing force of the coil spring 28 , and the pawl portion 27 b engages with the pawl receiving portion 19 below the pawl portion 19 . abuts and locks.
To remove the rear slide claw portion 27, lift the base plate 13 and slide the operation portion 27c to the right with a finger so that the claw portion 27b climbs over the claw receiving portion 19, thereby unlocking.

図９において、便器本体２は凹部９における後側受け部１８の下方に便鉢８内を洗浄するための水をリムに供給する通水部３３が設置され、管路３４を通して洗浄水が便鉢８内に流入するようになっている。
図１０は便器本体２の上面前方に設置した便座５とその後方に設置したカバー４とを示すものである。凹部９の上部に設置された機能部３を有するベースプレート１３は前方側に延びる両側の前側先端部１３ａが凹部９の突堤部９ａの前側に位置している。その上部に設置されるカバー４には便座５の回転軸部３６が左右に突出して形成され、回転軸部３６を中心に便座５が上下方向に回動可能とされている。
カバー４の後端側の側面４ａは略円筒状に形成されており、凹部９の略円弧状の突堤部９ａに沿って突堤部９ａを囲うように配設されて、側面４ａで突堤部９ａを覆っている。カバー４を突堤部９ａに対して若干持ち上げると隙間が形成され、この隙間を通して指を挿入して後側スライド爪部２７の操作部２７ｃをスライド操作することで、爪受け部１９と後側スライド爪部２７を離脱できる。 In FIG. 9, the toilet body 2 is provided with a water passage portion 33 for supplying water to the rim for washing the inside of the toilet bowl 8 below the rear receiving portion 18 in the concave portion 9. It is designed to flow into the bowl 8 .
FIG. 10 shows the toilet seat 5 installed in front of the upper surface of the toilet body 2 and the cover 4 installed behind it. A base plate 13 having a functioning portion 3 installed in the upper portion of the recess 9 has both front end portions 13a extending forwardly located in front of the jetty portion 9a of the recess 9. As shown in FIG. A rotating shaft portion 36 of the toilet seat 5 is formed on the cover 4 installed on the upper portion thereof so as to protrude to the left and right, and the toilet seat 5 can be rotated vertically around the rotating shaft portion 36 .
The side surface 4a on the rear end side of the cover 4 is formed in a substantially cylindrical shape, and is disposed along the substantially arc-shaped jetty portion 9a of the recess 9 so as to surround the jetty portion 9a. covering the When the cover 4 is slightly lifted with respect to the jetty portion 9a, a gap is formed. By inserting a finger through this gap and operating the operation portion 27c of the rear slide claw portion 27 to slide, the claw receiving portion 19 and the rear slide can be moved.
