Description

【0001】
【発明の属する技術分野】
本発明は水洗便器のうち、ボウル面の洗浄をポンプからの洗浄水で行うようにした水洗便器に関する。
【0002】
【従来の技術】
洗浄水をポンプを用いて供給するようにした水洗便器として、特開平6−264482号公報に開示されるものが知られている。
【0003】
特開平6−264482号公報にあっては、貯水タンク内の洗浄水をリム内を通水路とするリム部分に供給する洗浄水と大便器部分(ボウル部)に供給する洗浄水に分け、制御手段によって両方の洗浄水または一方の洗浄水を一定量だけポンプで供給することで、必要最小限の洗浄水で便器洗浄と汚物除去を行えるようにしている。
【0004】
また、従来のローシルエットの水洗便器は、洗浄水の供給方式として水道直結方式のものが多く採用されている。この水道直結式では、家屋の地理的状況によって水圧が変化するため低水圧時には水圧不足で設置不可能な場合があるし、高水圧時には、ゼット洗浄時に大流量の吐水が必要なために、バルブの開閉音が発生するという問題があった。
【0005】
【発明が解決しようとする課題】
特開平6−264482号記載の水洗便器は、大便器部分(ボウル部)洗浄途中において大便器部分のトラップが空になった状態でもトラップへ洗浄水を供給する状態(ブロー状態)が発生し、汚物排出直後の騒音が大きくなる問題があった。
【0006】
また、リム内を通水路とするためにこの通水路に洗浄水が流入して行く過程で通水路内の空気が圧縮されてリムに設けられた洗浄水吐水口から排出するときに圧搾音が発生したり、前記洗浄水吐出口を設けた部分が使用者からは死角となり清掃が容易に行えないという問題があった。
【0007】
また、サイホン水洗便器においては少ない洗浄水量でサイホン作用を早期に発生させるために大瞬間流量の洗浄水を排水路に供給する必要性があり、前記特開平6−264482号のようにポンプで供給するとすればポンプ容量が大きなものとなり、コンパクトな水洗便器を構成するのは空間的に困難である。
【0008】
そこで、本発明の目的は洗浄時に発生する音を極力低く抑え、リム部の清掃を容易に行うことができ、洗浄水を供給するためのポンプの容量が小さいポンプを採用することが可能で、コンパクト化が実現できる水洗便器を提供することである。
【0009】
【課題を解決するための手段】
上記課題を解決すべく本発明は、貯水タンクを備えるとともにボウル部に臨むリム内側面とボウル部の汚物受け面とを連続した曲面とした水洗便器であって、この便器は貯水タンク内の洗浄水を第1及び第2の流路に分け、第1の流路はゼット穴または押込洗浄水吐出口に連通させ、第2の流路はリム内側面と汚物受け面との境界部近傍に設けた吐水口に連通させ、前記第1の流路には重力で洗浄水を供給し、前記第2の流路にはポンプを介して一定圧の洗浄水を供給するようにした。
【0010】
かかる構成とすることで、またリム内を通水路とせず、直接ボウル内に吐水するために、先述したリム洗浄水吐水口からの空気圧搾音が発生しない。
【0011】
さらに、タンク内の洗浄水を重力式でゼット穴へ供給することで、洗浄途中において大便器部分のトラップが空になることがないため、前記ブロー状態が発生せず、汚物排出直後の騒音を防止することができる。
【0012】
また、水道の水圧を利用して洗浄しないために、水道からの給水は小流量で済むことになり、高圧時のバルブ給水音を最小化することができる。
【0013】
また、リム給水のみをポンプ式とすることで、ポンプ容量を低く抑えることができることにより、ポンプを小さく且つ静音に構成できるために、よりコンパクトでローシルエットな静音の水洗便器を実現することが可能である。
【0014】
前記貯水タンクとしては単一でもよいが、上下に2分割してもよい。上下に2分割した場合には、下部タンクを前記第1の流路につなげ、上部タンクを前記第2の流路につなげ、下部タンクの満水時ラインをリム上面よりも低く設定することで、放置時に下部タンク内の洗浄水がボウル面に溢れる現象(永久漏水)を防止できる。
また、貯水タンクを上下に2分割した場合には、上部タンクを介して下部タンクに給水する構造とするのが好ましい。
【0015】
【発明の実施の形態】
以下に本発明の実施の形態を添付図面に基づいて説明する。図1は本発明に係る水洗便器の平面図、図2は図1のA−A線に沿った断面図であり、水洗便器1は前方をボウル部2とし、後部に貯水タンク3を備えている。
【0016】
ボウル部2は椀状をなす汚物受け面4と上縁部を構成するリム5を有し、汚物受け面4とリム5の内側面とは段差などのないスムーズな曲面で連続している。そして、上から見て死角になる箇所がないように、また、清掃の際には使い捨ての紙等を使用して簡単にリム内側面を拭き取ることができ、しかも洗浄水が外に飛び出すことがないように、リム5の内側面6は図2に示すように内方に向かってある程度オーバーハングした形状になっている。
【0017】
また汚物受け面4の中央部には排水路につながる入口7が形成され、この排水路入口7にサイホン効果を高めるためのゼット穴8が開口し、このゼット穴8につながる貯水タンク3からの第1の流路9が設けられている。
【0018】
また、貯水タンク3からは第2の流路10を構成する配管が導出され、この第2の流路10の途中にポンプ11が設けられ、更に第2の流路10の先端には前記汚物受け面4とリム5の内側面との境界部に洗浄水を吐出する吐水口12が設けられている。
【0019】
貯水タンク3には止水栓13、配管14、ボールタップ15を介して洗浄水が供給され、供給された洗浄水の一部は重力で第1の流路9を介してゼット穴8に至り、また洗浄水の他の一部はポンプ11を介して一定圧で吐水口12から吐出し、旋回流となって汚物受け面4全面に行き渡りゼット穴8からの洗浄水とともに排水路に流入する。
【0020】
図3乃至図5は別実施例に係る水洗便器を示し、図3に示す実施例は配管14の中間に分岐バルブ16を設け、この分岐バルブ16から局部洗浄器への配管17を分岐している。
【0021】
図4に示す実施例は、第1の流路9を押込洗浄水吐出口18に連通している・この押込洗浄水吐出口18から排水路に洗浄水を流入せしめることで、サイホン効果を高めることができる。
【0022】
図5に示す実施例は、第2の流路10を構成する配管を2本設け、リムの内周面に沿った2箇所から洗浄水を吐出するようにしている。このように左右に離間した2箇所から1つの旋回流を形成する方向に洗浄水を吐出することで、洗浄効果を高めることができる。
【0023】
図6は貯水タンクの別実施例を示す断面図であり、この実施例にあっては貯水タンク3を上部タンク31と下部タンク32に分割し、止水栓からの配管33の途中にはボールタップ34でオン・オフするバルブ35が設けられ、このバルブ35の部分で配管36,37に分岐し、配管36は上部タンク31の上部に接続され、配管37は下部タンク32に給水する。
また上部タンク31と下部タンク32とは配管38にて接続され、上部タンク31を溢れた洗浄水は下部タンク32内に貯留される。
【0024】
また下部タンク32内に一定量の洗浄水が溜まるとボールタップ34によってバルブ35が閉じて給水が停止する。この状態での水位はリム上面よりも低くなるように設定されており、便器放置時の漏水が有効に防止される。
【0025】
更に、上部タンク31の底面39は傾斜面となっており、この底面の最も低い箇所に配管40が接続され、この配管40の途中にポンプ41が設けられ、ポンプ41から一定圧の洗浄水がリム側に供給される。
【0026】
【発明の効果】
以上に説明したように本発明に係る水洗便器は、貯水タンク内の洗浄水をポンプを介してボウル面に供給するようにしたので、ローシルエットでしかも一定圧の洗浄水をボウル面に供給できる。
【0027】
特に、ボウル部に臨むリム内側面と汚物受け面とをスムーズに連続した形状とし、この部分に洗浄水を吐出し旋回流を形成してボウル面全面に洗浄水を行き渡らせる形状の水洗便器にあっては、洗浄水の吐出圧を水道直結型に比較して一定にすることができ、安定した旋回流を形成することができる。
【0028】
また、貯水タンクを上下に分割し、下部タンクを重力でゼット穴または押込洗浄水吐出口に洗浄水を供給する第1の流路につなげ、上部タンクをポンプを介して一定圧の洗浄水を供給する第2の流路につなげる構成とすることで、効率よく洗浄水を各流路に送り出すことができ、特に、下部タンク内の最高水位をリム上面よりも低く設定しておくことで、放置時の漏水を防止できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a flush toilet, in which flushing of a bowl surface is performed with flush water from a pump.
[0002]
[Prior art]
A flush toilet disclosed in Japanese Patent Application Laid-Open No. 6-264482 is known as a flush toilet in which flush water is supplied using a pump.
[0003]
In JP-A-6-264482, cleaning water in a water storage tank is divided into cleaning water to be supplied to a rim portion serving as a water passage in the rim and cleaning water to be supplied to a toilet bowl portion (bowl portion). By means of means, both flushing water or one flushing water is supplied by a certain amount by a pump, so that toilet flushing and waste removal can be performed with a minimum necessary flushing water.
[0004]
In addition, many conventional low-profile silhouette flush toilets employ a direct water supply system as a system for supplying flush water. In this water supply direct connection type, the water pressure changes depending on the geographical situation of the house, so it may not be possible to install due to insufficient water pressure at low water pressure, and at high water pressure, a large flow rate of water is required during jet cleaning, so the valve There is a problem that the opening and closing noise of the sound is generated.
[0005]
[Problems to be solved by the invention]
In the flush toilet described in JP-A-6-264482, a state (blowing state) occurs in which flush water is supplied to the toilet bowl portion (bowl portion) even when the toilet bowl trap is empty during the flushing process (bowl portion). There was a problem that the noise immediately after the discharge of filth increased.
[0006]
Also, in order for the washing water to flow into the rim to make it into the rim, a compression noise is generated when the air in the culm is compressed and discharged from the washing water spout provided on the rim. There is a problem that the cleaning water cannot be easily cleaned due to the occurrence of blind spots or a blind spot from the user.
[0007]
Further, in the siphon flush toilet, it is necessary to supply a large instantaneous flow of flush water to a drainage channel in order to generate a siphon action early with a small flush water amount. Then, the pump capacity becomes large, and it is spatially difficult to construct a compact flush toilet.
[0008]
Therefore, an object of the present invention is to minimize the noise generated at the time of cleaning, to easily perform cleaning of the rim portion, and to adopt a pump having a small capacity of a pump for supplying cleaning water. An object of the present invention is to provide a flush toilet that can be made compact.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention is a flush toilet having a water storage tank and a continuous curved inner surface of a rim facing a bowl portion and a filth receiving surface of the bowl portion. Water is divided into first and second flow paths, the first flow path is communicated with a jet hole or a pushing flush water discharge port, and the second flow path is near a boundary between the inner surface of the rim and the waste receiving surface. The water outlet was provided, and the first flow path was supplied with cleaning water by gravity, and the second flow path was supplied with cleaning water at a constant pressure via a pump.
[0010]
With this configuration, since the water is directly discharged into the bowl without using the water passage in the rim, the above-described air compression noise from the rim washing water discharge port does not occur.
[0011]
Further, by supplying the washing water in the tank to the jet hole by gravity, the trap in the toilet section does not become empty during the washing, so that the blow state does not occur and the noise immediately after discharging the waste is reduced. Can be prevented.
[0012]
In addition, since cleaning is not performed using the water pressure of the water supply, the water supply from the water supply requires only a small flow rate, and the valve water supply sound at high pressure can be minimized.
[0013]
In addition, since only the rim water supply is pump type, the pump capacity can be kept low, and the pump can be made small and quiet, so that a more compact and low silhouette silent flush toilet can be realized. It is.
[0014]
The water storage tank may be single or may be divided into two vertically. In the case of splitting vertically, the lower tank is connected to the first flow path, the upper tank is connected to the second flow path, and the full line of the lower tank is set lower than the upper surface of the rim, The phenomenon that the washing water in the lower tank overflows to the bowl surface during standing (permanent water leakage) can be prevented.
When the water storage tank is divided into two vertically, it is preferable to supply water to the lower tank via the upper tank.
