Description

【０００１】
【発明の属する技術分野】
本発明は、人体局部に向け洗浄水を噴出する衛生洗浄装置の制御に関するものである。
【０００２】
【従来の技術】
従来、この種の衛生洗浄装置を、図７、図８を用いて説明する。図７で示すように衛生洗浄装置は、使用者が着座する便座１と、瞬間的に洗浄水を加熱する加熱手段５と、各機能の操作をする操作部２と、衛生洗浄装置を制御する制御手段３と、洗浄水を人体局部に噴出するスライド式の洗浄ノズル７と、局部洗浄時に洗浄ノズル７を洗浄位置まで突出させるノズル駆動手段９で構成され、使用者が操作部２を操作することにより人体局部洗浄が開始し、加熱手段５によって加熱された洗浄水をノズル駆動手段９によって洗浄ノズル７を洗浄位置に突出させた後にノズル先端の噴出孔８から洗浄水を噴出するように構成されていた。
【０００３】
図８は洗浄ノズル７への洗浄水の供給系を示すブロック図であり、洗浄水の流量調整機能を持つ洗浄水量調整弁１０、洗浄水を瞬間的に加熱する加熱手段５、洗浄ノズル７を洗浄位置まで突出させるノズル駆動手段９及び制御手段３を備え、加熱手段５と洗浄ノズル７との間には洗浄水量調整弁１０を組み込んでいる。
【０００４】
洗浄ノズル７は傾斜した中空体であり、そのノズル先端に複数の噴出孔８を開けたものである。このため、洗浄終了時に洗浄ノズル内部に残った洗浄水を自然落下によりノズル先端の噴出孔８から排出することができる。
【０００５】
【発明が解決しようとする課題】
しかしながら、前記従来の構成では、瞬間的に加熱することにより洗浄を行う場合には少量の洗浄水で所望の洗浄力を得る必要があり、空気を強制的に混入したり、脈動により瞬間的な洗浄水の速度を上げるなど様々な工夫がなされていた。一方、洗浄水量が少量であるため洗浄開始時に、洗浄ノズルを洗浄水の水圧にて洗浄位置まで突出させることができないため、モータを用いたノズル駆動手段を設け洗浄位置まで洗浄ノズルを突出させていた。従って、衛生洗浄装置内にノズル駆動手段を実装する必要があり衛生洗浄装置自体が小型化できない、或いは、安価な流体の圧力で突出させる洗浄ノズルに比べコストアップとなるという課題を有していた。
【０００６】
また、洗浄停止時にノズル本体内部に残った洗浄水を自然落下によりノズル先端の噴出孔から排出するように構成されているが、残った洗浄水が排出されにくく、完全に排出できないので、この残った洗浄水が時間が経過すると温水から冷水になり、次回使用するときこの冷水が局部に噴出されるという課題も有していた。
【０００７】
本発明は、前記従来の課題を解決するもので、流体の圧力で突出させる洗浄ノズルを用い、洗浄ノズルが洗浄位置まで突出しないときに、洗浄水に空気混入手段からの空気を混入させさせることにより、少流量の洗浄水でも洗浄ノズルを突出させることができるので衛生洗浄装置自体が小型化でき、かつ洗浄停止時に空気混入手段を付勢することにより洗浄ノズル内に残った洗浄水を排出することのできる衛生洗浄装置を提供することを目的とする。
【０００８】
【課題を解決するための手段】
前記従来の課題を解決するために、本発明の衛生洗浄装置は、流体の圧力により洗浄ノズルを突出させ人体局部に向け洗浄水を噴出するノズル手段と、瞬間的に洗浄水を加熱する加熱手段と、洗浄ノズルの突出位置を測定するノズル位置測定手段と、洗浄水に空気を混入する空気混入手段と、装置全体を制御する制御手段とからなり、制御手段は空気混入手段の混入する空気量及び空気混入タイミングを制御することにより洗浄ノズルを突出させることと、洗浄停止時に洗浄ノズル内部に残った洗浄水を排出することとしたものである。
【０００９】
【発明の実施の形態】
請求項１に記載の発明は、流体の圧力より洗浄ノズルを突出させ人体局部に向け洗浄水を噴出するノズル手段と、瞬間的に洗浄水を加熱する加熱手段と、前記洗浄ノズルの突出位置を測定するノズル位置測定手段と、洗浄水に空気を混入する空気混入手段と、前記空気混入手段の混入する空気量及び空気混入タイミングを制御することにより前記洗浄ノズルを突出させる制御手段とから構成したもので、少水量でも洗浄ノズルを突出させることができるので、装置自体を小型化でき、かつ廉価な衛生洗浄装置を提供するものである。
【００１０】
請求項２に記載の発明は、特に請求項１に記載の衛生洗浄装置に、洗浄時間を測定する洗浄時間測定手段を設け、制御手段は、洗浄開始から所定の時間が経過しても洗浄ノズルが洗浄位置まで突出していないとき、空気混入手段を動作させ洗浄ノズルを突出させるように構成したもので、洗浄開始時に少水量でも安定した洗浄ノズルの突出を行うことが出来る。
【００１１】
請求項３に記載の発明は、特に請求項１に記載の制御手段を洗浄開始時の空気混入手段の空気量をノズル位置測定手段からの洗浄ノズル突出位置に応じて調整し、洗浄ノズルを突出させるように構成したもので、洗浄開始時に少水量でも確実に洗浄ノズルの突出を行うことが出来る。
【００１２】
請求項４に記載の発明は、洗浄開始時の空気混入手段の空気量を洗浄時間測定手段からの経過時間に応じて調整し、洗浄ノズルを突出させるように構成したもので、洗浄開始時に少水量でも確実に洗浄ノズルの突出を行うことが出来る。
【００１３】
請求項５に記載の発明は、洗浄停止時に空気混入手段を付勢させることにより、洗浄ノズル内の残水を確実に排出させることができ、次回衛生洗浄装置を使用するときも快適な局部洗浄を提供することができる。
【００１４】
請求項６に記載の発明は、特に請求項１〜３に記載の制御手段を、ノズル位置測定手段による洗浄ノズル突出位置が所定の位置に達した後に、空気混入手段を停止させることにより、洗浄ノズル突出後は洗浄水に空気が混入しないので使用者に快適な局部洗浄を提供することができる。
【００１５】
【実施例】
以下、本発明の実施例について図１〜図６を参照しながら説明する。
【００１６】
（実施例１）
図１は本発明の第１の実施例における衛生洗浄装置のブロック図を示すものである。また、図２は本発明の第１の実施例における洗浄開始時に空気混入手段６が洗浄開始からのノズル位置測定値と空気混入手段６が洗浄水１１に混入する空気量との関係を示すものである。ここで、本発明の衛生洗浄装置は、流体の圧力にて突出する洗浄ノズル２９、洗浄ノズル２９の位置を測定するノズル位置測定手段４、洗浄水に空気を混入する空気混入手段６、瞬間的に洗浄水１１を加熱する加熱手段５、及び空気混入手段６を制御する制御手段３０とからなり、制御手段３０は、ノズル位置測定手段４からのノズル位置測定値により洗浄水１１に空気を混入させる空気混入手段６の空気量を制御する空気量制御手段３１、空気混入手段６を動作させるタイミングを判定する空気混入動作判定手段３２、ノズル位置測定手段４からのノズル位置測定値により洗浄ノズル２９が洗浄位置まで突出したか判定する洗浄ノズル突出判定手段３３とから構成されている。
【００１７】
洗浄ノズル突出判定手段３３は、図２に示すように洗浄開始から洗浄水１１の圧力によって突出する洗浄ノズル２９をノズル位置測定手段４からのノズル位置測定値が２０ｍｍになったとき空気混入動作判定手段３２が空気混入手段６を動作させる。このとき空気量制御手段３１は混入する空気量を６００ｃｃに設定し、すでに洗浄ノズル２９の流れ込んでいる洗浄水１１を押し出すように空気を混入させる。その後、空気量制御手段３１はノズル位置測定手段４が検出するノズル位置測定値によって空気混入手段６が混入する空気量を図２に示すように設定する。例えば、ノズル位置測定手段４のノズル位置測定値が４０ｍｍの場合、空気量制御手段３１が空気混入手段６により混入する空気量を３５０ｃｃ／分と設定し空気混入手段６を制御する。ノズル位置測定手段４のノズル位置測定値が洗浄位置である１００ｍｍになるまで、図２に示す関係で空気量制御手段３１は混入する空気量を制御する。
【００１８】
その後、図２に示すように洗浄開始からのノズル位置測定値が洗浄位置である１００ｍｍになるまで空気混入手段６を動作させると、洗浄ノズル２９が洗浄位置に突出したと洗浄ノズル突出判定手段３３が判定するので、ノズル位置測定値が１００ｍｍになったとき空気混入動作判定手段３２が空気混入手段６を停止させる。
【００１９】
以上のように、本実施例においては洗浄開始時のノズル位置測定手段４のノズル位置測定値を基に、空気混入動作判定手段３２が空気混入手段６の動作を制御し、更に空気混入手段６が動作中においては、ノズル位置測定手段４のノズル位置測定値を基に洗浄ノズル突出判定手段３３は洗浄ノズル２９が洗浄位置まで突出していないと判定したとき、空気量制御手段３１が混入する空気量を制御することにより、少水量でも洗浄ノズル２９を洗浄位置まで突出させ、使用者に安定した局部洗浄を提供することができる。
【００２０】
なお、本実施例では、空気混入開始のタイミングを、ノズル位置測定値が２０ｍｍに達したとき、及び空気混入停止のタイミングをノズル位置測定値が１００ｍｍに達したときとしているが、このノズル位置測定値は使用する洗浄ノズルによりこの値は適宜選択できるものである。
【００２１】
また、ノズル位置測定値と混入する空気量をリニアに変化させているが、これに限定するものではなく、洗浄ノズルの特性に合わせて任意の混入量を設定しても良いことは言うまでもない。
【００２２】
さらに、空気混入を停止しているが、強い洗浄力が必要な際には必要な量の空気混入を行うようにしてもよい。
【００２３】
（実施例２）
図３は本発明の第２の実施例における衛生洗浄装置のブロック図である。実施例１と異なる点は、制御手段３６に、洗浄開始からの洗浄時間を測定する洗浄時間測定手段３４を設けた点である。その他の構成要素については実施例１と同様であり、説明を省略する。洗浄時間測定手段３４は、洗浄開始からの洗浄時間を測定するものである。図４は本発明の第２の実施例における洗浄開始時に空気混入手段６が動作開始からの洗浄経過時間と空気混入手段６が洗浄水１１に混入する空気量との関係を示すものである。次に、洗浄時間測定手段３４の動作を説明する。図４のように洗浄開始から洗浄時間測定手段３４は洗浄時間を測定しており、この洗浄経過時間が２秒を経過したとき空気混入動作判定手段３２が空気混入手段６を動作させる。そのとき空気量制御手段３１は混入するの空気量を６００ｃｃに設定し、洗浄開始から２秒間洗浄ノズル２９の流れ込んでいる洗浄水１１を押し出すように空気を混入させる。その後洗浄時間測定手段３４の経過時間に応じて空気量制御手段３１は混入する空気量を６００ｃｃ／分より減少させる。洗浄ノズル２９が洗浄位置に突出したと洗浄ノズル突出判定手段３３が判断したとき、空気混入手段６を停止させる。例えば図４のように洗浄時間測定手段３４の洗浄経過時間が６秒経過時、洗浄ノズル２９が洗浄位置に突出したと洗浄ノズル突出判定手段３３が判断したとき空気混入手段６を停止させる。
【００２４】
以上のように、本実施例においては洗浄開始時の洗浄時間測定手段３４の洗浄経過時間を基に、空気混入動作判定手段３２が空気混入手段６の動作を、空気量制御手段３１が混入する空気量を制御することにより、少水量でも洗浄ノズル２９を洗浄位置まで突出させることにより、使用者に安定した局部洗浄を提供することができる。
【００２５】
（実施例３）
図５は本発明の第３の実施例における衛生洗浄装置のブロック図である。実施例２と異なる点は、制御手段３７に、洗浄停止からの経過時間を測定する洗浄停止時間測定手段３５を設け、ノズル位置測定手段４や洗浄ノズル突出判定手段３３や洗浄時間測定手段３４が無い点である。その他の構成要素については実施例２と同様であり、説明を省略する。洗浄停止時間測定手段３５は、洗浄停止中の時間を測定するものであり、洗浄停止状態になってからの経過時間を測定している。また、図６は本発明の第３の実施例における洗浄停止時における空気混入手段６が動作開始からの停止経過時間と空気混入手段６が残った洗浄水１１に混入する空気量との関係を示すものである。図６のように、洗浄停止時に空気混入動作判定手段３２が洗浄ノズル２９の残った洗浄水を排出するために空気を混入する必要があると判断し、空気混入手段６を動作させる。はじめの２秒間、空気量制御手段３１は混入する空気量を少しずつ増やし、その後２秒から６秒までの間は３００ｃｃ／分の空気を混入する。これにより洗浄ノズル２９に残った洗浄水１１は洗浄ノズル２９から押し出され全て排出することになる。洗浄停止時間測定手段３５の経過時間が６秒経過したとき、空気混入動作判定手段３２は洗浄ノズル２９に残った洗浄水１１をが全て排出されたと判断し空気混入手段６を停止させる。このように洗浄停止時に空気混入手段６から洗浄水１１を押し出すように空気を混入することで、洗浄ノズル２９に残った洗浄水を全て排出することになり、使用者が次回衛生洗浄装置を使用するときに、洗浄ノズル２９に残った洗浄水が局部に噴出されることがなく、快適な局部洗浄ができる。
【００２６】
以上のように、本実施例においては洗浄停止時の空気混入手段６から洗浄ノズル２９に残った洗浄水を押し出すように空気を混入することで洗浄水を全て排出することになり、使用者が次回衛生洗浄装置を使用するときも快適な局部洗浄を提供することができる。
【００２７】
前記実施例１〜３は、洗浄水１１を瞬間式に加熱する加熱手段５について記述しているが、洗浄水１１をタンクに給水し、洗浄する前に予め洗浄水を加熱する方式についても前記実施例１〜３のようにできる。この方式の場合の効果は、少量の洗浄水で局部洗浄できるためタンクを小型化することができ、衛生洗浄装置も小型化することができる効果を有する。
【００２８】
【発明の効果】
以上のように、本発明によれば、流体の水圧で突出させる洗浄ノズルを、洗浄水と共に空気混入手段からの空気を混入させさせることにより、少水量の時でも洗浄ノズルを突出させることができる。更に洗浄停止時に洗浄ノズルに空気を混入することで残った洗浄水を排出することになり、使用者が次回衛生洗浄装置を使用するとき、局部に残った洗浄水が噴出されることなく快適な局部洗浄を提供することができる。

Therefore, it is necessary to mount the nozzle driving means in the sanitary washing device, and there is a problem that the sanitary washing device itself cannot be miniaturized, or the cost is increased as compared with a washing nozzle that is protruded by inexpensive fluid pressure. .
[0006]
In addition, the cleaning water remaining in the nozzle body when the cleaning is stopped is configured to be discharged from the nozzle hole at the tip of the nozzle by natural fall. However, since the remaining cleaning water is difficult to discharge and cannot be completely discharged, the remaining cleaning water cannot be completely discharged. There is also a problem that after a lapse of time, the washing water changes from hot water to cold water, and this cold water is ejected to a local area at the next use.
[0007]

[0015]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
[0016]
(Example 1)
FIG. 1 is a block diagram showing a sanitary washing device according to a first embodiment of the present invention. FIG. 2 shows the relationship between the measured value of the nozzle position from the start of cleaning by the air mixing means 6 and the amount of air mixed into the cleaning water 11 by the air mixing means 6 at the start of cleaning in the first embodiment of the present invention. It is. Here, the sanitary washing device of the present invention includes a washing nozzle 29 protruding by the pressure of the fluid, a nozzle position measuring means 4 for measuring the position of the washing nozzle 29, an air mixing means 6 for mixing air into the washing water, A heating means 5 for heating the washing water 11 and a control means 30 for controlling the air mixing means 6. The control means 30 mixes air into the washing water 11 based on the measured nozzle position from the nozzle position measuring means 4. The air amount control means 31 for controlling the air amount of the air mixing means 6 to be caused to operate, the air mixing operation determining means 32 for determining the timing for operating the air mixing means 6, and the cleaning nozzle 29 based on the nozzle position measurement value from the nozzle position measuring means 4. And a cleaning nozzle protrusion judging means 33 for judging whether or not has protruded to the cleaning position.
[0017]
As shown in FIG. 2, the cleaning nozzle protrusion judging means 33 judges the aeration operation when the measured nozzle position from the nozzle position measuring means 4 becomes 20 mm. The means 32 operates the aeration means 6. At this time, the air amount control means 31 sets the mixed air amount to 600 cc, and mixes the air so as to push out the cleaning water 11 already flowing into the cleaning nozzle 29. Thereafter, the air amount control means 31 sets the amount of air mixed by the air mixing means 6 according to the nozzle position measurement value detected by the nozzle position measurement means 4 as shown in FIG. For example, when the nozzle position measurement value of the nozzle position measurement means 4 is 40 mm, the air amount control means 31 sets the amount of air mixed by the air mixing means 6 to 350 cc / min and controls the air mixing means 6. Until the nozzle position measurement value of the nozzle position measurement means 4 reaches the cleaning position of 100 mm, the air amount control means 31 controls the amount of air to be mixed in the relationship shown in FIG.
[0018]
Thereafter, as shown in FIG. 2, when the air mixing means 6 is operated until the measured value of the nozzle position from the start of the cleaning reaches the cleaning position of 100 mm, the cleaning nozzle protrusion judging means 33 determines that the cleaning nozzle 29 has protruded to the cleaning position. Is determined, the aeration operation determination means 32 stops the aeration means 6 when the measured nozzle position value reaches 100 mm.
[0019]
As described above, in the present embodiment, the aeration operation determining unit 32 controls the operation of the aeration unit 6 based on the nozzle position measurement value of the nozzle position measurement unit 4 at the start of cleaning. Is operating, when the cleaning nozzle protrusion determination means 33 determines that the cleaning nozzle 29 does not protrude to the cleaning position based on the nozzle position measurement value of the nozzle position measurement means 4, the air amount control means 31 By controlling the amount, the washing nozzle 29 can be protruded to the washing position even with a small amount of water, and a stable local washing can be provided to the user.
[0020]
In the present embodiment, the timing of the start of the air mixing is set when the measured value of the nozzle position reaches 20 mm, and the timing of the stop of the air mixing is set when the measured value of the nozzle position reaches 100 mm. The value can be appropriately selected depending on the cleaning nozzle used.
[0021]
In addition, the nozzle position measurement value and the amount of air to be mixed are linearly changed. However, the present invention is not limited to this, and it goes without saying that an arbitrary amount of mixing may be set in accordance with the characteristics of the cleaning nozzle.
[0022]
Further, although the air mixing is stopped, when a strong detergency is required, a necessary amount of air mixing may be performed.
[0023]
(Example 2)
FIG. 3 is a block diagram of a sanitary washing device according to a second embodiment of the present invention. The difference from the first embodiment is that the control means 36 is provided with a cleaning time measuring means 34 for measuring the cleaning time from the start of cleaning. Other components are the same as in the first embodiment, and a description thereof will be omitted. The cleaning time measuring means 34 measures the cleaning time from the start of cleaning. FIG. 4 shows the relationship between the elapsed cleaning time from the start of operation of the air mixing means 6 and the amount of air mixed into the cleaning water 11 by the air mixing means 6 at the start of cleaning in the second embodiment of the present invention. Next, the operation of the cleaning time measuring means 34 will be described. As shown in FIG. 4, the cleaning time measuring unit 34 measures the cleaning time from the start of the cleaning. When the cleaning elapsed time exceeds 2 seconds, the aeration operation determining unit 32 operates the aeration unit 6. At this time, the air amount control means 31 sets the mixed air amount to 600 cc and mixes the air so as to push out the washing water 11 flowing into the washing nozzle 29 for 2 seconds from the start of washing. Thereafter, according to the elapsed time of the cleaning time measuring means 34, the air amount control means 31 reduces the amount of air to be mixed to less than 600 cc / min. When the cleaning nozzle protrusion determination means 33 determines that the cleaning nozzle 29 has protruded to the cleaning position, the air mixing means 6 is stopped. For example, as shown in FIG. 4, when the cleaning elapsed time of the cleaning time measuring means 34 has elapsed for 6 seconds, when the cleaning nozzle protrusion determining means 33 determines that the cleaning nozzle 29 has protruded to the cleaning position, the air mixing means 6 is stopped.
[0024]
As described above, in the present embodiment, the operation of the air entrainment means 6 is performed by the air entrainment operation determining means 32 and the air amount control means 31 is entrained by the air entrainment operation means 32 based on the elapsed cleaning time of the cleaning time measuring means 34 at the start of cleaning. By controlling the amount of air and projecting the washing nozzle 29 to the washing position even with a small amount of water, stable local washing can be provided to the user.
[0025]
(Example 3)
FIG. 5 is a block diagram of a sanitary washing device according to a third embodiment of the present invention. The difference from the second embodiment is that the control means 37 is provided with a cleaning stop time measuring means 35 for measuring the elapsed time from the stop of the cleaning, and the nozzle position measuring means 4, the cleaning nozzle protrusion judging means 33 and the cleaning time measuring means 34 are provided. There is no point. Other components are the same as in the second embodiment, and a description thereof will be omitted. The washing stop time measuring means 35 measures the time during which washing is stopped, and measures the elapsed time after the washing is stopped. FIG. 6 shows the relationship between the time elapsed from the start of the operation of the aeration unit 6 and the amount of air mixed in the remaining cleaning water 11 with the aeration unit 6 when the cleaning is stopped in the third embodiment of the present invention. It is shown. As shown in FIG. 6, when cleaning is stopped, the air mixing operation determining means 32 determines that it is necessary to mix air in order to discharge the remaining cleaning water from the cleaning nozzle 29, and operates the air mixing means 6. During the first 2 seconds, the air amount control means 31 gradually increases the amount of air to be mixed in, and thereafter mixes 300 cc / min of air for 2 to 6 seconds. As a result, the cleaning water 11 remaining in the cleaning nozzle 29 is pushed out from the cleaning nozzle 29 and is entirely discharged. When the elapsed time of the cleaning stop time measuring means 35 has elapsed for 6 seconds, the air mixing operation determining means 32 determines that all the cleaning water 11 remaining in the cleaning nozzle 29 has been discharged, and stops the air mixing means 6. As described above, when the cleaning is stopped, the air is mixed into the air mixing means 6 so as to push out the cleaning water 11, so that all the cleaning water remaining in the cleaning nozzle 29 is discharged. When the cleaning is performed, the cleaning water remaining in the cleaning nozzle 29 is not spouted to the local area, and a comfortable local cleaning can be performed.
[0026]
As described above, in the present embodiment, all the cleaning water is discharged by mixing air from the air mixing means 6 at the time of cleaning stop so as to push out the cleaning water remaining in the cleaning nozzle 29, and the user can perform the cleaning. The comfortable local cleaning can be provided also when the next use of the sanitary cleaning device.
[0027]
The first to third embodiments describe the heating means 5 for heating the cleaning water 11 instantaneously. However, the method of supplying the cleaning water 11 to the tank and heating the cleaning water in advance before cleaning is also described. Examples 1 to 3 can be used. The effect of this method is that local cleaning can be performed with a small amount of washing water, so that the tank can be reduced in size, and the sanitary washing device can also be reduced in size.

【The invention's effect】
As described above, according to the present invention, the cleaning nozzle protruding by the hydraulic pressure of the fluid is mixed with the cleaning water and the air from the air mixing means, whereby the cleaning nozzle can be protruded even when the amount of water is small. . Furthermore, the remaining washing water is discharged by mixing air into the washing nozzle when washing is stopped, so that the next time the user uses the sanitary washing device, the washing water remaining in the local area is not jetted out and comfortable. Local cleaning can be provided.
