従来、水洗便器本体に内蔵されてボウルから延びる排水管にトラップ部を連通した水洗便器として、例えば、特許文献１の内容が知られている。   Conventionally, for example, the content of Patent Document 1 is known as a flush toilet with a trap portion communicated with a drain pipe that is built in a flush toilet body and extends from a bowl.

図４に示すように、特許文献１の水洗便器５０は、図示しない便器本体のボウルから延びる排出管部５０ａに一端が固定端５５として連通されるとともに他端を自由端５１とする可動トラップ部５３を備える。可動トラップ部５３は外部排水管５２と連結するケース体５６の内部に収容され、外部排水管５２は床下に導かれる。この可動トラップ部５３の自由端５１は、自由端５１に連結された回転アーム６０によって、モータ駆動の回転軸５８によって矢印Ａで示すように上下方向に回転自在である。   As shown in FIG. 4, the flush toilet 50 of Patent Document 1 includes a movable trap portion in which one end communicates with a discharge pipe portion 50 a extending from a bowl of a toilet body (not shown) as a fixed end 55 and the other end is a free end 51. 53. The movable trap portion 53 is accommodated in a case body 56 connected to the external drain pipe 52, and the external drain pipe 52 is guided under the floor. A free end 51 of the movable trap portion 53 is rotatable in the vertical direction as indicated by an arrow A by a rotation shaft 58 driven by a motor by a rotary arm 60 connected to the free end 51.

そして、モータ駆動の回転軸５８と便器本体ボウルに給水する図示しない給水弁とを制御して、通常の溜め水時には上向き位置にある可動トラップ部５３の自由端５１を矢印Ｂで示すように反転させて傾け、矢印Ｃで示すように自由端５１から排水をオーバーフロー水として流れ出るようにするセルフクリーニング機構を備える。   Then, the motor-driven rotating shaft 58 and a water supply valve (not shown) for supplying water to the toilet bowl are controlled so that the free end 51 of the movable trap portion 53 in the upward position is reversed as indicated by an arrow B during normal reservoir water. And a self-cleaning mechanism that causes the drainage to flow out as overflow water from the free end 51 as shown by an arrow C.

セルフクリーニング機構は、可動トラップ部５３の外側部の洗浄をするために、手動スイッチによるセルフクリーニングと用便後に自動的に行う自動セルフクリーニングを選択して実施できる。   The self-cleaning mechanism can select and carry out self-cleaning by a manual switch and automatic self-cleaning automatically performed after stool in order to clean the outer portion of the movable trap portion 53.

このような水洗便器５０では、自由端５１が反転して外部排水管５２の位置まで下降するので、排出管部５０ａとケース体５６の排水口５６ａとの間に十分な落差Ｈが得られるので汚物が十分に洗い流せるため可動トラップ部５３内に浮遊残汚物がほとんど発生しない。
特開平１１−２１００５５号公報 In such a flush toilet 50, since the free end 51 is reversed and descends to the position of the external drain pipe 52, a sufficient drop H is obtained between the drain pipe portion 50a and the drain outlet 56a of the case body 56. Since the filth can be washed away sufficiently, the floating filth is hardly generated in the movable trap portion 53.
Japanese Patent Laid-Open No. 11-210055

ところが、水洗便器の後側の床面上に外部排水管が設けられる場合がある。この場合の排水動作を図５を用いて説明する。図５（ａ）に示すように、水洗便器５０のボウル５９から延びる排出管部５０ａに可動トラップ部５３の一端が固定端５５として固定され、可動トラップ部５３の自由端５１は上方で便器本体のボウル５９内に洗浄水Ｓが溜め水状態である。排水管５２ａは床面５７上に導かれる。   However, an external drain pipe may be provided on the floor surface behind the flush toilet. The draining operation in this case will be described with reference to FIG. As shown in FIG. 5A, one end of the movable trap portion 53 is fixed as a fixed end 55 to the discharge pipe portion 50a extending from the bowl 59 of the flush toilet 50, and the free end 51 of the movable trap portion 53 is above the toilet body. Wash water S is stored in the bowl 59. The drain pipe 52a is guided onto the floor surface 57.

図５（ｂ）に示すように、用便後に可動トラップ部５３の自由端５１を略水平状態にして排水する。そして、図５（ｃ）に示すように、可動トラップ部５３の自由端５１が上方に戻り、図５（ｄ）に示すように、可動トラップ部５３内が溜め水状態になる。   As shown in FIG. 5 (b), after the stool, the free end 51 of the movable trap part 53 is placed in a substantially horizontal state for draining. Then, as shown in FIG. 5 (c), the free end 51 of the movable trap portion 53 returns upward, and as shown in FIG. 5 (d), the inside of the movable trap portion 53 is in a pooled water state.

ここで、排水管５２ａが床面５７上に設けられるので、図５（ｂ）における便器本体の排出管部５０ａと可動トラップ部５３の自由端５１との間の落差Ｈ１は図４の状態の落差Ｈと比べて少ないため、排水時の水勢が十分得られないので可動トラップ部５３内部に浮遊残汚物Ｔが残留することがあった。   Here, since the drain pipe 52a is provided on the floor surface 57, the drop H1 between the discharge pipe portion 50a of the toilet body and the free end 51 of the movable trap portion 53 in FIG. Since it is less than the head H, a sufficient amount of water at the time of drainage cannot be obtained, so that floating residue T may remain inside the movable trap portion 53.

本発明は、このような事情に鑑みてなされたものであり、水洗便器の後方に排水管が設けられる水洗便器で、用便後にトラップ部の溜め水に残る浮遊残汚物を効率よく確実に排出することができる水洗便器の洗浄構造および洗浄方法の提供を目的としている。   The present invention has been made in view of such circumstances, and is a flush toilet in which a drain pipe is provided behind the flush toilet, and efficiently and reliably discharges floating residual matter remaining in the trap water after the stool.

以下に、本発明の実施形態を図１〜図３に基づいて説明する。   Embodiments of the present invention will be described below with reference to FIGS.

＜水洗便器の洗浄構造の構成＞
図１に示すように、本実施形態の水洗便器３０は、水洗便器本体３１に内蔵されるボウル１の底部から延びる排水管３の終端に管状のトラップ部６が連通されている。 <Configuration of flush toilet cleaning structure>
As shown in FIG. 1, in the flush toilet 30 of the present embodiment, a tubular trap portion 6 is communicated with an end of a drain pipe 3 extending from the bottom of the bowl 1 built in the flush toilet body 31.

トラップ部６は床１８上に配置される外部排水管４に連結するケース体８内に収容される。トラップ部６の一端部は排水管３に固定端として固定され他端は自由端９で、この自由端９に固定される支持部材９ａがトラップ部６の外側に対称的に配設された回転自在の一対のアーム１０ａの先端に連結される。   The trap portion 6 is accommodated in a case body 8 connected to the external drain pipe 4 disposed on the floor 18. One end of the trap portion 6 is fixed as a fixed end to the drain pipe 3 and the other end is a free end 9. A support member 9 a fixed to the free end 9 is symmetrically disposed outside the trap portion 6. It is connected to the tip of a pair of free arms 10a.

ここで、回転軸１５ａを回転する電動駆動手段１３はモータ１２と第一ギア１４と第二ギア１５ａとで構成され、図示しない便器洗浄スイッチの起動によってモータ１２を回転して第一ギア１４と第二ギア１５を駆動し、第二ギア１５の回転軸１５ａに連結する一対のアーム１０ａに回転力が伝達される。   Here, the electric drive means 13 for rotating the rotary shaft 15a is composed of a motor 12, a first gear 14, and a second gear 15a. The rotational force is transmitted to the pair of arms 10 a that drive the second gear 15 and are connected to the rotation shaft 15 a of the second gear 15.

このように、水洗便器３０の排水路は、排水管３、トラップ部６、ケース部８および外部排水管４によって形成され、回転軸１５ａを介して上下方向に回転するトラップ部６の自由端９が下方回転した状態においてトラップ部６は略水平状態である。なお、便器本体ボウル２に給水する給水弁２０を水洗便器本体３１に備える。   Thus, the drainage channel of the flush toilet 30 is formed by the drainage pipe 3, the trap part 6, the case part 8, and the external drainage pipe 4, and the free end 9 of the trap part 6 that rotates in the vertical direction via the rotating shaft 15a. The trap portion 6 is in a substantially horizontal state in a state in which is rotated downward. The flush toilet body 31 is provided with a water supply valve 20 for supplying water to the toilet body bowl 2.

トラップ部６は蛇腹状のホース７で形成され、ホース７の材質は弾力性に優れて伸縮および屈曲自在な、樹脂、ゴム等の材質が採用される。
図２、図３を用いてトラップ部６の動作を説明するが、図３において「図２における各状態との対応位置」が示されるので、図２の動作説明に図３の内容が含まれるので図３の説明は省略する。なお、トラップ部６の動作は便器洗浄スイッチを一度押すだけで図示しない内部リレー回路により図２（ａ）から図２（ｆ）まで連続的に実施される。 The trap portion 6 is formed of a bellows-like hose 7, and the material of the hose 7 is made of a material such as resin or rubber that has excellent elasticity and can be expanded and contracted and bent.
The operation of the trap unit 6 will be described with reference to FIGS. 2 and 3, but “corresponding positions with respect to the respective states in FIG. 2” are shown in FIG. 3, so the description of FIG. 2 includes the contents of FIG. 3. Therefore, the description of FIG. 3 is omitted. The operation of the trap unit 6 is continuously carried out from FIG. 2A to FIG. 2F by an internal relay circuit (not shown) only by pressing the toilet flushing switch once.

図２（ａ）に示すように、通常時には、トラップ部６の自由端９が上方を向いた状態で、ボウル内部には自由端９の高さまで洗浄水Ｓが溜っている状態である。   As shown in FIG. 2A, in a normal state, the free end 9 of the trap portion 6 faces upward, and the cleaning water S is accumulated up to the height of the free end 9 inside the bowl.

図２（ｂ）に示すように、用便後に便器洗浄スイッチを押すとモータ１２が正転してトラップ部６が略水平状態となり自由端９が便器後方の外部排水管４の位置で停止するので汚物は溜水である洗浄水Ｓとともに外部排水管４に排出される。なお、図２（ｂ）から図２（ｆ）の状態に亘って、給水弁２０の作動により洗浄水Ｓはボウル１に連続的に供給される。   As shown in FIG. 2 (b), when the toilet flushing switch is pushed after the stool, the motor 12 rotates forward, the trap portion 6 becomes substantially horizontal, and the free end 9 stops at the position of the external drain pipe 4 behind the toilet. Therefore, the filth is discharged to the external drainage pipe 4 together with the cleaning water S that is stored water. 2B to FIG. 2F, the cleaning water S is continuously supplied to the bowl 1 by the operation of the water supply valve 20.

図２（ｃ）に示すように、モータ１２が逆転してトラップ部６の自由端９が上方向に回転する。この状態で浮遊残汚物Ｔが自由端９近傍に存在している。   As shown in FIG. 2 (c), the motor 12 reverses and the free end 9 of the trap portion 6 rotates upward. In this state, the floating residue T is present near the free end 9.

しばらくして、図２（ｄ）に示すように洗浄水Ｓが上限位置に到達して初期位置としての溜め水状態に戻る。   After a while, as shown in FIG. 2D, the cleaning water S reaches the upper limit position and returns to the accumulated water state as the initial position.

図２（ｅ）に示すように、再度自由端９を上方位置と略水平位置の中間位置まで回転して溜め水Ｓを流すことで、自由端９近傍に存在している浮遊残汚物Ｔを流し出すことができる。   As shown in FIG. 2 (e), the free end 9 is rotated again to an intermediate position between the upper position and the substantially horizontal position and the pooled water S is allowed to flow, so that the floating waste T present in the vicinity of the free end 9 is removed. Can be washed out.

その後、図２（ｆ）に示すように、再度トラップ部６の自由端９を上方に反転して洗浄水Ｓが上限位置まで溜められる。   Thereafter, as shown in FIG. 2 (f), the free end 9 of the trap portion 6 is again turned up again, and the cleaning water S is accumulated to the upper limit position.

＜水洗便器の洗浄構造の作用＞
トラップ部６を動作して浮遊残汚物Ｔを洗浄水Ｓとともに便器後方に排出したのち、再度トラップ部６の自由端９を上向きに反転して洗浄水Ｓを注入した後、自由端９を再度回転して洗浄水Ｓを流すので、このトラップ部６の二度の排出動作によって浮遊残汚物Ｔを確実に流し出すことができる。 <Operation of flush toilet cleaning structure>
After operating the trap part 6 to discharge the floating waste T together with the wash water S to the rear of the toilet, the free end 9 of the trap part 6 is turned upside down again to inject the wash water S, and then the free end 9 is again inserted. Since the cleaning water S is rotated to flow, the floating residue T can be surely discharged by the two discharging operations of the trap portion 6.

以上、本発明の実施例を図面に基づいて説明したが、具体的な構成はこの実施例に限られるものではなく本発明の要旨を逸脱しない範囲の設計変更等があっても本発明に含まれる。   The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within the scope of the present invention are included in the present invention. It is.

たとえば、トラップ部６を動作して浮遊残汚物Ｔを洗浄水Ｓとともに便器後方に流し出す動作において、トラップ部６の二度目の排出動作は一度目と同様にトラップ部６の自由端９を略水平位置近傍まで回転させてもよい。   For example, in the operation of operating the trap unit 6 to discharge the floating residual waste T together with the washing water S to the rear of the toilet bowl, the second discharging operation of the trap unit 6 is substantially the same as the first time with the free end 9 of the trap unit 6 being omitted. You may rotate to the horizontal position vicinity.

この場合、二度目のトラップ部動作におけるトラップ部６の自由端９が略水平位置に近づくほど浮遊残汚物Ｔの排出効果が向上するが使用水量も増えるので、浮遊残汚物Ｔの状況を勘案して二度目の自由端９の下方位置が設定される。   In this case, as the free end 9 of the trap section 6 in the second trap section operation approaches the substantially horizontal position, the effect of discharging the floating waste T is improved, but the amount of water used increases, so the situation of the floating waste T is taken into consideration. Thus, the lower position of the second free end 9 is set.

トラップ部動作は毎回の用便に連動する自動設定以外に手動でも動作することができる。   The trap unit can be operated manually in addition to the automatic setting linked to each flight.
