Description

本発明は、便器のリム通水路に洗浄水を供給して便鉢を洗浄する便器洗浄装置に係り、特にリム通水路への給水方向を切り替えるように構成された便器洗浄装置に関する。   The present invention relates to a toilet bowl cleaning apparatus that supplies cleaning water to a rim water passage of a toilet bowl to wash a toilet bowl, and more particularly, to a toilet bowl cleaning apparatus configured to switch a water supply direction to a rim water passage.

洋風便器の便鉢の上縁に設けられたリム通水路に洗浄水を供給して鉢面に旋回流を形成させて鉢面を洗浄する便器洗浄装置は周知である。   A toilet cleaning device that supplies cleaning water to a rim water passage provided on an upper edge of a toilet bowl of a Western-style toilet and forms a swirling flow on the bowl surface to wash the bowl surface is well known.

従来の便器洗浄装置は、リム通水路への給水方向は一方向であり、鉢面に形成される旋回流の旋回方向は常に同一方向となっている。   In the conventional toilet flushing apparatus, the water supply direction to the rim water passage is one direction, and the swirl direction of the swirl flow formed on the bowl surface is always the same direction.

このように常に同一方向に旋回流を形成させるようにした洋風便器にあっては、鉢面に部分的に水が行き届きにくい箇所が生じ、その箇所に汚れが付着残留しがちとなる。   Thus, in a Western-style toilet device in which a swirl flow is always formed in the same direction, a portion where water is difficult to reach partially occurs on the bowl surface, and dirt tends to adhere to the portion.

このような短所を解決しようとするものとして、特開2002−302988号公報の第0018段落、図2等には、リム通水路への給水方向を絶えず交互に切り替え、右回りの水流を左回りの水流とがぶつかる位置を変化させ、鉢面を均一に洗浄する便器洗浄装置が記載されている。
特開2002−302988号公報
In order to solve such disadvantages, Japanese Patent Application Laid-Open No. 2002-302988, paragraph 0018, FIG. 2 and the like indicate that the water supply direction to the rim water passage is constantly switched alternately, and the clockwise water flow is counterclockwise. A toilet bowl cleaning device that changes the position where the water flow collides with the water flow and cleans the bowl surface uniformly is described.
JP 2002-302988 A

上記特開2002−302988号公報の便器洗浄装置にあっては、右回りの水が左回りの水とがぶつかり、このぶつかった水はそのまま便鉢のトラップ部に落下してしまうため、鉢面を周回する旋回流が殆ど形成されず、鉢面の洗浄が不十分なものとなり易い。   In the toilet cleaning device of the above-mentioned JP-A No. 2002-302988, the clockwise water collides with the counterclockwise water, and this bumped water falls into the trap part of the toilet bowl as it is. The swirling flow that circulates around is hardly formed, and the bowl surface tends to be insufficiently washed.

本発明は、鉢面を洗い残し無く極めて十分に洗浄することができる便器洗浄装置を提供することを目的とする。   An object of this invention is to provide the toilet bowl washing | cleaning apparatus which can wash | clean very sufficiently, without leaving unwashed a pot surface.

本発明(請求項1)の便器洗浄装置は、便鉢の上縁に沿って延設されたリム通水路に洗浄水を供給する便器洗浄装置において、該リム通水路に対し一方向に洗浄水を供給して便鉢内に該一方向の旋回流を形成し、次いで、該一方向への洗浄水を停止し、所定時間後に該リム通水路に対し反対方向に洗浄水を供給して便鉢内に反対方向の旋回流を形成するように構成されていることを特徴とするものである。   The toilet bowl cleaning device of the present invention (Claim 1) is a toilet cleaning apparatus for supplying cleaning water to a rim water passage extending along the upper edge of a toilet bowl. To form a swirl flow in one direction in the toilet bowl, and then stop washing water in the one direction, and after a predetermined time, supply washing water in the opposite direction to the rim water passage. It is configured to form a swirling flow in the opposite direction in the pot.

かかる本発明の便器洗浄装置によると、例えば鉢面に左回りの旋回流を形成するように左回り方向に洗浄水を供給し、次いでこの給水を停止し、左回りの旋回流が停止するか又は著しく弱くなってから右回り方向に洗浄水を供給して鉢面に右回りの旋回流を形成する。このように、左回りと右回りの双方の旋回流を形成すると共に、両者の給水時間帯を離隔させ、左回り旋回流と右回り旋回流とが全く又は殆どぶつからないようにしているので、いずれの旋回流も鉢面全体に十分に行き渡るようになり、鉢面を十分に洗浄することが可能となる。   According to the toilet cleaning device of the present invention, for example, the wash water is supplied counterclockwise so as to form a counterclockwise swirling flow on the bowl surface, and then this water supply is stopped, and the counterclockwise swirling flow is stopped. Alternatively, the water is supplied in the clockwise direction after it becomes extremely weak to form a clockwise swirling flow on the bowl surface. In this way, both the counterclockwise and the clockwise swirl flow are formed, and the water supply time zones of both are separated so that the counterclockwise swirl flow and the clockwise swirl flow do not collide at all. Any swirling flow is sufficiently distributed over the entire bowl surface, and the bowl surface can be sufficiently washed.

As a result, a clockwise swirling flow is formed.

鉢部2のトラップ部には、該トラップ部にサイホン排出流を誘起するための水(ジェット水)を噴出するジェットノズル5が設けられている。このトラップ部は、鉢部2の底部から斜め上方に立ち上がる上昇部と、該上昇部に連なり、下方に立ち下がる立下部とを有しており、この立下部が排水管(図示略)に連なっている。このトラップ構造自体は周知のものである。   The trap portion of the bowl portion 2 is provided with a jet nozzle 5 that ejects water (jet water) for inducing a siphon discharge flow into the trap portion. This trap part has a rising part that rises obliquely upward from the bottom of the pot part 2 and a rising part that continues to the rising part and falls downward, and this rising part is connected to a drain pipe (not shown). ing. This trap structure itself is well known.

洋風便器1の後部上面に便座ボックス6が設置されている。この便座ボックス6の後部は洋風便器1よりも若干後方に張り出し、その下側にアンダーケース7が連なっている。便座ボックス6に対し便座8及び便蓋9が起倒回動しうるように支持されている。   A toilet seat box 6 is installed on the rear upper surface of the western-style toilet 1. The rear portion of the toilet seat box 6 protrudes slightly rearward from the western-style toilet 1 and an undercase 7 is connected to the lower side thereof. The toilet seat 8 and the toilet lid 9 are supported with respect to the toilet seat box 6 so that they can be turned upside down.

トイレルームの壁面には給水管の末端が突出しており、この給水管の末端に止水栓10が取り付けられている。この止水栓10は給水ホース11を介して洋風便器1の後部に設置されたストレーナ12に接続されている。このストレーナ12を通過した水は電動弁ユニット20へ供給可能とされている。   The end of the water supply pipe protrudes from the wall surface of the toilet room, and a stop cock 10 is attached to the end of the water supply pipe. This stop cock 10 is connected to a strainer 12 installed at the rear part of the Western-style toilet 1 via a water supply hose 11. The water that has passed through the strainer 12 can be supplied to the electric valve unit 20.

電動弁ユニット20は、内部に配置された弁装置(以下、単に弁ということがある。)22a,22b,23をモータ21で駆動し、リムノズル給水配管24a,24b又はジェットノズル給水配管25へ水を供給する。   The electric valve unit 20 drives valve devices (hereinafter also simply referred to as valves) 22a, 22b, and 23, which are disposed inside, by a motor 21, and supplies water to the rim nozzle water supply pipes 24a and 24b or the jet nozzle water supply pipe 25. Supply.

なお、停電時にも便器を使用できるようにするために、モータ21の回転軸に手動式の洗浄ハンドル28が取り付けられている。この電動弁ユニット20は、便座ボックス6からアンダーケース7内に配置されている。   Note that a manual washing handle 28 is attached to the rotating shaft of the motor 21 so that the toilet can be used even during a power failure. The electric valve unit 20 is arranged from the toilet seat box 6 into the undercase 7.

この電動弁ユニット20には、リムノズル用給水配管24a,24b内及びジェットノズル用給水配管25内の負圧をブレークするためのバキュームブレーカ26a,26b,27が設けられている。このバキュームブレーカ26a,26b,27は、該給水配管24a,24b又は25内に負圧が生じたときに開弁して該給水配管24a,24b又は25内を大気に連通させるよう構成されている。   The electric valve unit 20 is provided with vacuum breakers 26a, 26b, 27 for breaking negative pressures in the rim nozzle water supply pipes 24a, 24b and the jet nozzle water supply pipe 25. The vacuum breaker 26a, 26b, 27 is configured to open when a negative pressure is generated in the water supply pipe 24a, 24b, or 25, and to communicate the water supply pipe 24a, 24b, or 25 with the atmosphere. .

用便(大便)後に洋風便器1に洗浄水を供給するときには、第2,3図に示すように、まず弁22aが所定時間開弁し、リムノズル4aから水道水圧によってリム3へ洗浄水が供給され、鉢面に左回りの旋回流が形成される。次に、弁22aが閉弁して所要時間Tが経過した後、22bが所定時間開弁し、リムノズル4bから水道水圧によってリム3へ洗浄水が供給され、鉢面に右回りの旋回流が形成される。   When supplying wash water to the Western-style toilet 1 after a stool (stool), as shown in FIGS. 2 and 3, first, the valve 22a is opened for a predetermined time, and the wash water is supplied from the rim nozzle 4a to the rim 3 by tap water pressure. Thus, a counterclockwise swirling flow is formed on the bowl surface. Next, after the valve 22a is closed and the required time T elapses, the valve 22b is opened for a predetermined time. Wash water is supplied from the rim nozzle 4b to the rim 3 by tap water pressure, and a clockwise swirling flow is generated on the bowl surface. It is formed.

この弁22bの閉弁後、ある程度時間が経過した後、又は閉弁と略同時に、弁23が所定時間開弁し、ジェットノズル5から水が噴出してトラップ部にサイホンが誘起され、汚水が排水管へ排出される。その後、弁23が閉弁し、次いで弁22a,22bの一方又は双方(この実施の形態では弁22aのみ)が再度所要時間開弁し、トラップ水が貯溜される。   After a certain amount of time has elapsed after the valve 22b is closed, or substantially simultaneously with the valve closing, the valve 23 is opened for a predetermined time, water is ejected from the jet nozzle 5 and siphon is induced in the trap portion, and sewage is generated. It is discharged to the drain pipe. Thereafter, the valve 23 is closed, and then one or both of the valves 22a and 22b (only the valve 22a in this embodiment) are opened again for the required time, and trap water is stored.

なお、弁22a,22bの開弁時間は同一でもよく、異なっていてもよい。弁22aが閉弁してから弁22bが開弁するまでの待機時間Tは、左回り旋回流が停止するか又は著しく弱くなるように選定される。洗浄水量や水圧にもよるが、通常はTは2〜10秒程度、特に3〜6秒程度が好適である。   The valve opening times of the valves 22a and 22b may be the same or different. The waiting time T from when the valve 22a is closed until the valve 22b is opened is selected so that the counterclockwise swirling flow stops or becomes significantly weaker. Although it depends on the amount of washing water and the water pressure, usually T is preferably about 2 to 10 seconds, particularly about 3 to 6 seconds.

上記実施の形態では、左回りの旋回流を先に形成しているが、右回りの旋回流を先に形成してもよい。また、左回りと右回りの洗浄の後に、所定時間後、さらに再度左回り洗浄を繰り返してもよく、この再度の左回り洗浄の後に、所定時間経過後、再度の右回り洗浄を行ってもよい。   In the above embodiment, the counterclockwise swirl flow is formed first, but the clockwise swirl flow may be formed first. In addition, after a predetermined time after the counterclockwise and clockwise cleaning, the counterclockwise cleaning may be repeated again. After the counterclockwise cleaning, the counterclockwise cleaning may be performed again after the predetermined time has elapsed. Good.

上記実施の形態では左右2個のノズル24a,24bを設けているが、吐出方向切替可能な1個のノズルを設けてもよい。   In the above embodiment, the two nozzles 24a and 24b are provided on the left and right, but one nozzle capable of switching the ejection direction may be provided.

上記実施の形態では水道水圧によって洗浄水を供給しているが、ロータンクやハイタンク等の貯水でリム洗浄する場合にも本発明を適用することができる。   In the above embodiment, the cleaning water is supplied by the tap water pressure, but the present invention can also be applied to the case where the rim is cleaned by storing water such as a low tank or a high tank.
