Description

本発明は、浴槽を洗浄する浴槽洗浄装置、および浴槽洗浄方法に関するものである。   The present invention relates to a bathtub cleaning apparatus and a bathtub cleaning method for cleaning a bathtub.

近年、微細気泡は、水処理、洗浄、化学、医療等、さまざまなプロセスに応用されている。微細気泡の中でも、特に気泡の直径が1mm以下のものは、マイクロバブルと呼ばれている。マイクロバブルを含む微細気泡は、直径が1mm以上の通常の気泡と比べて液中での浮力が小さく、長時間にわたり液中に滞留し続ける。洗浄分野では、微細気泡の気液界面に汚れが吸着する性質を応用している。特に、気泡の直径が100μm以下の微細気泡には、洗浄効果が高いとされる。   In recent years, fine bubbles have been applied to various processes such as water treatment, cleaning, chemistry, and medical treatment. Among the fine bubbles, those having a bubble diameter of 1 mm or less are called microbubbles. Fine bubbles including microbubbles have a small buoyancy in the liquid compared to normal bubbles having a diameter of 1 mm or more, and remain in the liquid for a long time. In the field of cleaning, the property of adsorbing dirt on the gas-liquid interface of fine bubbles is applied. In particular, a fine bubble having a bubble diameter of 100 μm or less has a high cleaning effect.

また、入浴後の浴槽は、水面付近に喫水線と呼ばれる汚れが付着する。これは、皮脂、ほこり、シャンプー、ボディーソープ等に起因する汚れで、汚れ付着後に放置すると、汚れが浴槽に固着し、洗浄が困難になる。そこで、微細気泡を用いて、汚れが付着した浴槽を洗浄する浴槽洗浄装置が提案されている(例えば、特許文献1参照)。   Moreover, in the bathtub after bathing, dirt called a water line adheres near the water surface. This is dirt caused by sebum, dust, shampoo, body soap, etc. If left after the dirt adheres, the dirt adheres to the bathtub and is difficult to clean. Then, the bathtub washing | cleaning apparatus which wash | cleans the bathtub to which dirt adhered using the fine bubble is proposed (for example, refer patent document 1).

特許文献1に記載の浴槽洗浄装置は、浴槽の壁面に設けられた気泡含有水流発生装置により、微細気泡を含む水流を浴槽の壁面に接触するように浴水の張られた浴槽内に発生させることで、浴槽の壁面を洗浄するものである。   The bathtub cleaning apparatus described in Patent Literature 1 generates a water flow containing fine bubbles in a bathtub in which bath water is stretched so as to come into contact with the wall surface of the bathtub by a bubble-containing water flow generator provided on the wall surface of the bathtub. In this way, the wall surface of the bathtub is washed.

Next, the operation of the cleaning apparatus according to the first embodiment will be described.
FIG. 2 is a schematic diagram showing a flowchart of cleaning according to Embodiment 1 of the present invention.
The cleaning process (S100) of the cleaning apparatus according to the first embodiment includes a first cleaning process (S10), a flow path switching process (S20), and a second cleaning process (S30). Done. The cleaning is started after the bathing is completed. At this time, cleaning is started by operating a button or the like by a person, setting a timer, or the like.

図3は、本発明の実施の形態1に係る洗浄第一工程(S10)のフローチャートを示す概略図であり、図4は、本発明の実施の形態1に係る洗浄第一工程(S10)を示す概略図であり、図5は、本発明の実施の形態1に係る洗浄第一工程(S10)における浴槽1上部からの鳥瞰を示す概略図である。
洗浄開始後、図3に示すように、洗浄第一工程(S10)では、まず、浴槽1内に水を一定時間供給する(S11)。具体的には、図4に示すように、浴槽1内の水位である水面20が入浴時に発生する喫水線23より上の位置となるように、水供給源9からの水を水流発生装置3により浴槽1内に供給する。このとき、第一吐水口2aおよび第二吐水口2bのどちらから浴槽1内に水を供給してもよい。なお、浴槽1内の水面20が喫水線23より10cm以上、上の位置となることが望ましい。また、浴槽1内に水を供給する時間は、浴槽1の形状等により決定される。
FIG. 3 is a schematic diagram showing a flowchart of the first cleaning step (S10) according to Embodiment 1 of the present invention, and FIG. 4 shows the first cleaning step (S10) according to Embodiment 1 of the present invention. FIG. 5 is a schematic diagram showing a bird's-eye view from the upper part of the bathtub 1 in the first cleaning step (S10) according to Embodiment 1 of the present invention.
After the start of cleaning, as shown in FIG. 3, in the first cleaning step (S10), first, water is supplied into the bathtub 1 for a certain period of time (S11). Specifically, as shown in FIG. 4, water from the water supply source 9 is supplied by the water flow generator 3 so that the water surface 20, which is the water level in the bathtub 1, is positioned above the water line 23 generated during bathing. Supply into the bathtub 1. At this time, water may be supplied into the bathtub 1 from either the first water outlet 2a or the second water outlet 2b. In addition, it is desirable for the water surface 20 in the bathtub 1 to be at a position 10 cm or more above the water line 23. The time for supplying water into the bathtub 1 is determined by the shape of the bathtub 1 and the like.

一定時間経過後、浴槽アダプタ2からの水流の吐出先を、設置壁面と平行な方向に水流を吐出する第一吐水口2aに切り換え(S12)、第一吐水口2aから水流を吐出し、一定時間、浴槽1内の浴水に微細気泡を含んだ水流を発生させる(S13)。このとき浴槽1では、図4および図5に示すように、第一吐水口2aから水流を吐出することで、設置壁面と平行な上下左右方向に水流が吐出されるため、浴槽アダプタ2の近傍に強力な水流が形成される。なお、以下、浴槽アダプタ2の近傍に形成される強力な水流を水中水流21と称する。この水中水流21には、微細気泡発生装置5で発生させた微細気泡が含まれているため、微細気泡が浴槽アダプタ2の近傍の浴槽1の壁面(以下、近傍壁面22と称する)に作用して、当該近傍壁面22の汚れを効果的に洗浄することができる。   After a certain period of time, the discharge destination of the water flow from the bathtub adapter 2 is switched to the first water discharge port 2a that discharges the water flow in a direction parallel to the installation wall surface (S12), the water flow is discharged from the first water discharge port 2a, and is constant A water flow containing fine bubbles is generated in the bath water in the bathtub 1 for a time (S13). At this time, in the bathtub 1, as shown in FIGS. 4 and 5, the water flow is discharged in the vertical and horizontal directions parallel to the installation wall surface by discharging the water flow from the first water outlet 2 a, so that the vicinity of the bathtub adapter 2. A strong water flow is formed. Hereinafter, a strong water flow formed in the vicinity of the bathtub adapter 2 is referred to as an underwater water flow 21. Since the underwater water flow 21 contains fine bubbles generated by the fine bubble generator 5, the fine bubbles act on the wall surface of the bathtub 1 in the vicinity of the bathtub adapter 2 (hereinafter referred to as the nearby wall surface 22). Thus, the dirt on the nearby wall surface 22 can be effectively cleaned.

このとき、洗浄率を高めるために、吐出水量は、3.0L/min以上で、浴水に含まれる微細気泡の密度は、気泡径100μm以下の気泡が2000個/L以上であることが望ましい。また、浴槽1内の浴水は、微細気泡発生装置5で発生させた微細気泡で満たされるため、浴槽1の壁面全体の喫水線23の汚れが浮きあがり、喫水線23の汚れは洗浄されやすくなる。そのため、近傍壁面22の喫水線23の汚れを水中水流21により洗浄することができる。
浴槽1内の浴水に一定時間水流を発生させた後、第一吐水口2aからの水流の吐出を停止し、浴水の水流を停止させて(S14)、流路切換工程(S20)に移る。
At this time, in order to increase the cleaning rate, the discharge water amount is preferably 3.0 L / min or more, and the density of fine bubbles contained in the bath water is desirably 2000 bubbles / L or more with a bubble diameter of 100 μm or less. . Moreover, since the bath water in the bathtub 1 is filled with fine bubbles generated by the fine bubble generating device 5, dirt on the water line 23 on the entire wall surface of the bathtub 1 is lifted, and dirt on the water line 23 is easily cleaned. Therefore, dirt on the water line 23 on the nearby wall surface 22 can be washed by the underwater water flow 21.
After a water flow is generated in the bath water in the bathtub 1 for a certain time, the discharge of the water flow from the first outlet 2a is stopped, the water flow of the bath water is stopped (S14), and the flow path switching step (S20) is performed. Move.

図6は、本発明の実施の形態1に係る流路切換工程(S20)のフローチャートを示す概略図である。
図6に示すように、流路切換工程(S20)では、まず、浴槽1内の浴水を排水口6より排水する(S21)。その後、水位検知手段10により浴槽1内の水位を検知し、浴槽1内の水面20が浴槽アダプタ2より下の位置であることを検知したら、制御装置12は、浴水が浴槽1から排水されたと判断して(S22のYes)、流路切換装置7に信号を送る。そして、浴槽アダプタ2からの水流の吐出先を、設置壁面と垂直な方向に水流を吐出する第二吐水口2bに切り換え(S23)、洗浄第二工程(S30)に移る。
FIG. 6 is a schematic diagram showing a flowchart of the flow path switching step (S20) according to Embodiment 1 of the present invention.
As shown in FIG. 6, in the flow path switching step (S20), first, the bath water in the bathtub 1 is drained from the drain port 6 (S21). Then, if the water level in the bathtub 1 is detected by the water level detection means 10 and it is detected that the water surface 20 in the bathtub 1 is below the bathtub adapter 2, the control device 12 drains the bath water from the bathtub 1. (Yes in S22), a signal is sent to the flow path switching device 7. And the discharge destination of the water flow from the bathtub adapter 2 is switched to the 2nd water outlet 2b which discharges a water flow in the direction perpendicular | vertical to an installation wall surface (S23), and moves to a washing | cleaning 2nd process (S30).

図7は、本発明の実施の形態1に係る洗浄第二工程(S30)のフローチャートを示す概略図であり、図8は、本発明の実施の形態1に係る洗浄第二工程(S30)を示す概略図であり、図9は、本発明の実施の形態1に係る洗浄第二工程(S30)における浴槽1上部からの鳥瞰を示す概略図であり、図10は、本発明の実施の形態1に係る空中水流24の垂直方向の角度を示す概略図であり、図11は、本発明の実施の形態1に係る空中水流24の水平方向の角度を示す概略図である。   FIG. 7 is a schematic diagram showing a flowchart of the second cleaning step (S30) according to Embodiment 1 of the present invention, and FIG. 8 shows the second cleaning step (S30) according to Embodiment 1 of the present invention. FIG. 9 is a schematic view showing a bird's-eye view from the upper part of the bathtub 1 in the second cleaning step (S30) according to Embodiment 1 of the present invention, and FIG. 10 is an embodiment of the present invention. 1 is a schematic diagram showing the angle in the vertical direction of the aerial water stream 24 according to FIG. 1, and FIG. 11 is a schematic diagram showing the angle in the horizontal direction of the aerial water stream 24 according to Embodiment 1 of the present invention.

図7に示すように、洗浄第二工程(S30)では、まず、一定時間の経過を待つ(S31)。これは、(S22)において、浴槽1内の水面20が浴槽アダプタ2より下の位置であることを検知したら、制御装置12は、浴水が浴槽1から排水されたと判断しているが、実際に浴水の排水は完了していない。そのため、一定時間の経過を待って浴水の排水を完了させるためである。なお、このときの時間は、浴槽1のサイズ、形状、排水速度等から決定される。   As shown in FIG. 7, in the second cleaning step (S30), first, the passage of a fixed time is waited (S31). In (S22), when it is detected that the water surface 20 in the bathtub 1 is located below the bathtub adapter 2, the control device 12 determines that the bath water has been drained from the bathtub 1, but in practice, However, the drainage of bath water has not been completed. Therefore, the drainage of the bath water is completed after waiting for a certain period of time. In addition, the time at this time is determined from the size, shape, drainage speed, etc. of the bathtub 1.

その後、第二吐水口2bから水流を吐出し、一定時間、浴槽1内に微細気泡を含んだ水流を供給する(S32)。このとき、浴水は浴槽1から排水されており、浴槽1内に入っていないため、図8および図9に示すように、第二吐水口2bから空中に向かって水流が吐出される。そして、その水流は浴槽アダプタ2から遠方の壁面(以下、遠方壁面25と称する)に直接当たる。なお、以下、空中に吐出される水流を空中水流24と称する。   Then, a water flow is discharged from the 2nd spout 2b, and the water flow containing the fine bubble is supplied in the bathtub 1 for a fixed time (S32). At this time, since the bath water is drained from the bathtub 1 and does not enter the bathtub 1, as shown in FIGS. 8 and 9, a water flow is discharged from the second water outlet 2 b toward the air. The water flow directly hits a wall surface far from the bathtub adapter 2 (hereinafter referred to as a far wall surface 25). Hereinafter, the water flow discharged into the air is referred to as an air current 24.

ここで、浴槽洗浄装置は、第二吐水口2bから吐出する水流を上下左右方向に振動可能な機構を備えている。そして、空中水流24の振動角度は、図10および図11に示す角度で振動する。このように、第二吐水口2bから空中に吐出される空中水流24を上下左右方向に振動させることにより、遠方壁面25の広範囲を洗浄することができる。また、空中水流24には、微細気泡発生装置5で発生させた微細気泡が含まれているため、微細気泡が遠方壁面25に作用して、当該遠方壁面25の汚れを効果的に洗浄することができる。   Here, the bathtub cleaning device includes a mechanism capable of vibrating the water flow discharged from the second water discharge port 2b in the vertical and horizontal directions. And the vibration angle of the aerial water flow 24 vibrates at the angle shown in FIG. 10 and FIG. Thus, the wide area of the far wall surface 25 can be cleaned by vibrating the aerial water flow 24 discharged from the second water discharge port 2b into the air in the vertical and horizontal directions. In addition, since the aerial water flow 24 includes fine bubbles generated by the fine bubble generating device 5, the fine bubbles act on the far wall surface 25 to effectively clean the far wall surface 25. Can do.

図10に示すように、垂直方向の角度θ1およびθ2、詳しくは、浴槽アダプタ2を上下に分断する水平面に対して上向きの角度θ1、および前記水平面に対して下向きの角度θ2は、寸法L、H、H0から以下のように決まる。ここで、Lは、第二吐水口2bから第二吐水口2bと対向する浴槽1の短手側の壁面までの距離、Hは、浴槽1の底面から喫水線23までの高さ、H0は、浴槽1の底面から第二吐水口2bまでの高さである。
θ1=arctan(L/H) ・・・・・・(1)
θ2=arctan(0.05H0) ・・・・・・(2)
As shown in FIG. 10, the vertical angles θ1 and θ2, specifically, the angle θ1 upward with respect to the horizontal plane that divides the bathtub adapter 2 up and down, and the angle θ2 downward with respect to the horizontal plane are the dimension L, It is determined as follows from H and H0. Here, L is the distance from the second water outlet 2b to the short-side wall of the bathtub 1 facing the second water outlet 2b, H is the height from the bottom surface of the bathtub 1 to the water line 23, and H0 is It is the height from the bottom surface of the bathtub 1 to the second water discharge port 2b.
θ1 = arctan (L / H) (1)
θ2 = arctan (0.05H0) (2)

また、図11に示すように水平方向の角度θ3とθ4、詳しくは、浴槽アダプタ2を左右に分断する鉛直面に対して右向きの角度θ3、および前記鉛直面に対して左向きの角度θ4は、寸法D1、D2から、以下のように決まる。ここで、D1は、第二吐水口2bから浴槽1の長手側の一方の壁面までの距離、D2は、第二吐水口2bから浴槽1の長手側のもう一方の壁面までの距離である。
θ3=arctan(0.05D1) ・・・・・・(3)
θ4=arctan(0.05D2) ・・・・・・(4)
Further, as shown in FIG. 11, horizontal angles θ3 and θ4, specifically, an angle θ3 facing right with respect to the vertical plane dividing the bathtub adapter 2 to the left and right, and an angle θ4 facing left with respect to the vertical plane, From the dimensions D1 and D2, it is determined as follows. Here, D1 is the distance from the second water outlet 2b to one wall surface on the long side of the bathtub 1, and D2 is the distance from the second water outlet 2b to the other wall surface on the long side of the bathtub 1.
θ3 = arctan (0.05D1) (3)
θ4 = arctan (0.05D2) (4)

なお、洗浄率を高めるために、吐出水量は、3.0L/min以上であることが望ましい。また、洗浄第一工程(S10)と浄第二工程(S30)とでは、使用する浴槽アダプタ2の吐水口が異なり、吐出水量および吐出水圧は、水流発生装置3と水供給源9とにより、個別に調整可能および設定可能である。つまり、第一吐水口2aおよび第二吐水口2bは、それぞれ吐出水量および吐出水圧が、調整可能および設定可能である。   In order to increase the cleaning rate, the discharge water amount is desirably 3.0 L / min or more. Moreover, in the 1st washing | cleaning process (S10) and the 2nd purification process (S30), the spout of the bathtub adapter 2 to be used differs, and discharge water amount and discharge water pressure are the water flow generator 3 and the water supply source 9, Individually adjustable and configurable. That is, in the first water outlet 2a and the second water outlet 2b, the discharge water amount and the discharge water pressure can be adjusted and set, respectively.

浴槽1内に一定時間水流を吐出した後、第二吐水口2bからの水流の吐出を停止し(S33)、洗浄終了となる。   After the water flow is discharged into the bathtub 1 for a certain time, the discharge of the water flow from the second water discharge port 2b is stopped (S33), and the cleaning is completed.

空中水流24が浴槽1の壁面に当たる水圧は、水中での水流と比べて強くなるため、水中水流21よりも空中水流24の方が高い洗浄効果が得られる。また、洗浄第一工程(S10)で、浴槽1内の水面20が喫水線23より上の位置となるように水を供給して、微細気泡の効果により喫水線23の汚れを浮きあがらせているため、喫水線23の汚れは洗浄されやすい。そのため、遠方壁面25の喫水線23の汚れは空中水流24により洗浄することができる。   Since the water pressure at which the aerial water stream 24 hits the wall surface of the bathtub 1 is stronger than the underwater water stream, the aerial water stream 24 has a higher cleaning effect than the underwater water stream 21. Further, in the first cleaning step (S10), water is supplied so that the water surface 20 in the bathtub 1 is positioned above the water line 23, and dirt on the water line 23 is raised due to the effect of fine bubbles. The dirt on the water line 23 is easy to be cleaned. Therefore, the dirt on the water line 23 on the far wall 25 can be cleaned by the aerial water flow 24.

なお、本実施の形態1において、微細気泡発生装置5の微細気泡発生方式は、エジェクタ方式であることが望ましい。これは、動力を必要とせず安価であり、吸気の間欠等により、発生する気泡径を設定しやすいためである。   In the first embodiment, it is desirable that the fine bubble generation method of the fine bubble generator 5 is an ejector method. This is because it does not require power and is inexpensive, and it is easy to set the diameter of the generated bubbles by intermittent intake.

また、微細気泡の中でも、直径が1mm以下のマイクロバブルと称される気泡は、体積に対して表面積が非常に大きい特徴を有する。また、気泡の表面は疎水性のため、皮脂等の汚れを吸着する性質を有する。これらのことから、マイクロバブルを多く発生させて、汚れに接触させることで、汚染された部品等を洗浄することができる。マイクロバブルの中でも特に、直径100μm以下の気泡を多く発生させることで、高効率の洗浄を達成することができる。本実施の形態1では、このような微細気泡表面が持つ吸着作用を利用して、浴槽1の壁面等に付着する汚れを除去する。   Among the fine bubbles, bubbles called microbubbles having a diameter of 1 mm or less have a feature that the surface area is very large with respect to the volume. Further, since the surface of the bubbles is hydrophobic, it has a property of adsorbing dirt such as sebum. For these reasons, contaminated parts and the like can be cleaned by generating a large number of microbubbles and bringing them into contact with dirt. In particular, highly efficient cleaning can be achieved by generating many bubbles having a diameter of 100 μm or less among microbubbles. In the first embodiment, dirt adhering to the wall surface or the like of the bathtub 1 is removed using the adsorption action of the surface of such fine bubbles.

図12は、本発明の実施の形態1に係る洗浄第一工程(S10)の微細気泡を含まない水流での洗浄結果を示す概略図であり、図13は、本発明の実施の形態1に係る洗浄第一工程(S10)の微細気泡を含む水流での洗浄結果を示す概略図であり、図14は、本発明の実施の形態1に係る洗浄第二工程(S30)の微細気泡を含む水流での洗浄結果を示す概略図である。   FIG. 12 is a schematic diagram showing a cleaning result in a water flow that does not contain fine bubbles in the first cleaning step (S10) according to the first embodiment of the present invention, and FIG. 13 shows the first embodiment of the present invention. It is the schematic which shows the washing | cleaning result in the water flow containing the fine bubble of the said washing | cleaning 1st process (S10), FIG. 14 contains the fine bubble of the washing | cleaning 2nd process (S30) which concerns on Embodiment 1 of this invention. It is the schematic which shows the washing | cleaning result by a water flow.

なお、浴槽1の壁面に相当する洗浄試験片には、アクリル製人工大理石を用いた。また、汚れには、皮脂汚れを模擬して、ゼラチン1gと脂肪酸グリセリンエステル0.5gとを70度の湯水30mLに溶解させて振とうさせて発生した泡を用いた。そして、この汚れをアクリル製人工大理石の表面に0.1g塗布して、50度の恒温槽に1時間放置させて、汚れを固着させた。   An acrylic artificial marble was used for the cleaning test piece corresponding to the wall surface of the bathtub 1. For the dirt, foam generated by simulating sebum dirt and dissolving 1 g of gelatin and 0.5 g of fatty acid glycerin ester in 30 mL of 70 ° C. hot water was used. And 0.1g of this dirt was applied to the surface of the artificial marble made of acrylic, and left in a thermostatic bath at 50 degrees for 1 hour to fix the dirt.

図12および図13に示す洗浄結果は、図4および図5に示す近傍壁面22のうち、任意の位置を洗浄位置としたものであり、3つの洗浄位置での洗浄結果をそれぞれ示している。図12および図13に示すように、水流により近傍壁面22が洗浄可能であることを確認した。また、微細気泡を含む水流の方が、微細気泡を含まない水流よりも洗浄効果が高いことを確認した。   The cleaning results shown in FIGS. 12 and 13 are obtained by setting an arbitrary position in the vicinity wall surface 22 shown in FIGS. 4 and 5 as the cleaning position, and show the cleaning results at three cleaning positions, respectively. As shown in FIGS. 12 and 13, it was confirmed that the nearby wall surface 22 can be cleaned by a water flow. It was also confirmed that the water flow containing fine bubbles had a higher cleaning effect than the water flow containing no fine bubbles.

図14に示す洗浄結果は、図8および図9に示す遠方壁面25のうち、任意の位置を洗浄位置としたものであり、3つの洗浄位置での洗浄結果をそれぞれ示している。図15に示すように、空中水流24の方が、水中水流21よりも壁面に当たる水圧が強いため、より短時間で洗浄が可能であることを確認した。   The cleaning result shown in FIG. 14 is obtained by setting an arbitrary position on the far wall surface 25 shown in FIGS. 8 and 9 as the cleaning position, and shows the cleaning results at three cleaning positions, respectively. As shown in FIG. 15, it was confirmed that the aerial water flow 24 was able to be washed in a shorter time because the water pressure hitting the wall surface was stronger than the underwater water flow 21.

本実施の形態1に係る浴槽洗浄において、入浴した日は、入浴終了直後に行うことが望ましい。これは、時間が経過すると浴槽1に汚れが強固に固着してしまう場合があるためであり、入浴終了直後の汚れが固着する前であれば、汚れが落ちやすいためである。
また、家族構成の違いにより、入浴人数、年代、入浴時間等が異なり、浴槽1に付着する汚れが変化する。そのため、入浴人数、時間等が通常より少ない等の理由により、入浴後の浴槽1の壁面の汚れ付着量が軽微な場合は、洗浄第一工程の実施後に浴槽1の壁面全体が洗浄されていることが確認できれば、流路切換工程および洗浄第二工程を省略してもよい。
In the bathtub cleaning according to the first embodiment, it is desirable to perform the bathing day immediately after the bathing is completed. This is because the dirt may firmly adhere to the bathtub 1 over time, and the dirt is likely to be removed before the dirt immediately after the bathing is fixed.
In addition, the number of bathers, the age, the bathing time, and the like differ depending on the family structure, and the dirt attached to the bathtub 1 changes. Therefore, when the amount of dirt on the wall surface of the bathtub 1 after bathing is slight due to reasons such as the number of bathers, time, etc. being less than usual, the entire wall surface of the bathtub 1 is cleaned after the first cleaning step. If this can be confirmed, the flow path switching step and the second cleaning step may be omitted.

一方で、入浴人数が多く、入浴時間が長い等の条件によっては、浴槽1に汚れが強固に固着してしまう場合がある。そのため、洗浄力を向上させるためには、水中の微細気泡の数を多くする必要がある。しかし、水中の微細気泡が多くなりすぎると、気泡同士が合一して気泡が大きくなるため、かえって洗浄効果が低下してしまう。   On the other hand, depending on conditions such as a large number of bathers and a long bathing time, dirt may firmly adhere to the bathtub 1. Therefore, in order to improve the cleaning power, it is necessary to increase the number of fine bubbles in the water. However, if there are too many fine bubbles in the water, the bubbles are united to increase the size of the bubbles, so that the cleaning effect is reduced.

そこで本実施の形態1では、界面活性剤などの気泡同士の合一を抑制する働きを有する添加剤を浴水に添加することで、微細気泡発生装置5で発生した気泡を浴水中で安定化させて、高密度の微細気泡を発生させることができる。添加剤としては、有機系添加剤ではポリエチレングリコール等の高分子化合物等、無機系では炭酸水素ナトリウム(いわゆる、重曹またはベーキングパウダー)等がある。また、市販の入浴剤または洗浄剤を用いることもできる。入浴剤は含有成分として、無機塩類、生薬類、酵素類、有機酸類のうち、少なくとも1種類以上の添加物を含むものが望ましい。   Therefore, in the first embodiment, the bubbles generated by the fine bubble generator 5 are stabilized in the bath water by adding to the bath water an additive having a function of suppressing the coalescence of bubbles such as a surfactant. Thus, high-density fine bubbles can be generated. Examples of additives include organic compounds such as polymer compounds such as polyethylene glycol, and inorganic additives such as sodium hydrogen carbonate (so-called baking soda or baking powder). Commercially available bathing agents or cleaning agents can also be used. The bathing agent preferably contains at least one additive among inorganic salts, herbal medicines, enzymes, and organic acids as a component.

また、洗浄剤では界面活性剤を含有すること望ましい。添加剤の濃度としては、0.1ppm〜1000ppmの範囲で用いることが望ましい。これは、添加剤の濃度が低すぎると、添加剤の効果が現れず、微細気泡の数が増えないためである。また、濃度が高すぎると、洗浄後に洗浄物へ多くの添加剤成分が残留するため、すすぎに多量の水や時間が必要になるためである。なお、添加剤の添加方法としては、浴槽1に手動で添加するが、自動供給装置を浴槽1、または、水配管4の任意の箇所に設置してもよい。   Moreover, it is desirable that the detergent contains a surfactant. The concentration of the additive is desirably used in the range of 0.1 ppm to 1000 ppm. This is because if the concentration of the additive is too low, the effect of the additive does not appear and the number of fine bubbles does not increase. On the other hand, if the concentration is too high, many additive components remain in the washed product after washing, so that a large amount of water and time are required for rinsing. In addition, although it adds manually to the bathtub 1 as an addition method of an additive, you may install an automatic supply apparatus in the arbitrary locations of the bathtub 1 or the water piping 4. FIG.

添加剤を使用した場合、洗浄終了後は、手動によりシャワーで浴槽1の壁面をすすぎ、浴水を一定時間注水して、水配管4内に残る洗浄剤等の添加物を洗い流す。または、再度、浴槽1に浴水を満たし、再び洗浄工程(S100)を実施してもよい。   When the additive is used, after the cleaning is completed, the wall surface of the bathtub 1 is manually rinsed with a shower, and bath water is poured for a certain period of time to wash away additives such as a cleaning agent remaining in the water pipe 4. Alternatively, the bath 1 may be filled again with the bath water and the cleaning step (S100) may be performed again.

以上のように、本実施の形態1に係る洗浄装置は、浴槽1内の水位が喫水線23よりも上に位置する状態で、第一吐水口2aから水流を吐出し、一定時間、浴槽1内の浴水に微細気泡を含んだ水流を発生させることで、近傍壁面22の汚れを洗浄することができる。また、浴槽1内の水位が0、つまり、浴槽1内から浴水が排水されている状態で、第二吐水口2bから水流を吐出し、一定時間、浴槽1内に微細気泡を含んだ水流を供給することで、遠方壁面25の汚れを洗浄することができる。そのため、浴槽全体を均一に洗浄することができる。   As described above, the cleaning device according to the first embodiment discharges a water flow from the first water outlet 2a in a state where the water level in the bathtub 1 is located above the water line 23, and the inside of the bathtub 1 for a certain period of time. By generating a water flow containing fine bubbles in the bath water, the dirt on the nearby wall surface 22 can be washed. In addition, in the state where the water level in the bathtub 1 is 0, that is, the bath water is drained from the bathtub 1, a water flow is discharged from the second outlet 2b, and the water flow containing fine bubbles in the bathtub 1 for a certain period of time. By supplying, dirt on the far wall surface 25 can be cleaned. Therefore, the entire bathtub can be washed uniformly.

実施の形態2.
以下、本実施の形態2について説明するが、実施の形態1と重複するものについては省略し、実施の形態1と同じ部分または相当する部分には同じ符号を付す。
図15は、本発明の実施の形態2に係る洗浄装置の構成を示す概略図である。
本実施の形態2では、水位検知手段10および制御装置12が、信号線11とは別の信号線202により、それぞれ演算器201に接続されている。また、制御装置12と水供給源9とは、信号線203で接続されている。
Embodiment 2. FIG.
Hereinafter, although Embodiment 2 will be described, the same elements as those in Embodiment 1 are omitted, and the same or corresponding parts as those in Embodiment 1 are denoted by the same reference numerals.
FIG. 15 is a schematic diagram showing a configuration of a cleaning apparatus according to Embodiment 2 of the present invention.
In the second embodiment, the water level detection means 10 and the control device 12 are each connected to the calculator 201 by a signal line 202 different from the signal line 11. The control device 12 and the water supply source 9 are connected by a signal line 203.

図16は、本発明の実施の形態2に係る洗浄第一工程(S40)のフローチャートを示す概略図である。なお、流路切換工程(S20)および、図示省略の洗浄第二工程(S30)は、実施の形態1と同じフローチャートである。
以下、本実施の形態2に係る洗浄装置の動作について説明する。
本実施の形態2では、水位検知手段10および演算器201を用いて浴槽1内に水を供給する(S41)。具体的には、水位検知手段10により浴槽1内の浴水の水圧等を検知して、その水圧等に基づいて、演算器201により浴槽1内の水位を計算する。そして、図4に示す浴槽1内の水面20が喫水線23より10cm以上、上となると、制御装置12は水供給源9に水供給停止を指令する。これにより、浴槽1内の水面20と喫水線23との距離を正確に自動で検知することができるため、水の供給量を削減することができる。
FIG. 16 is a schematic diagram showing a flowchart of the first cleaning step (S40) according to Embodiment 2 of the present invention. The flow path switching step (S20) and the cleaning second step (S30) (not shown) are the same flowcharts as in the first embodiment.
Hereinafter, the operation of the cleaning apparatus according to the second embodiment will be described.
In the second embodiment, water is supplied into the bathtub 1 using the water level detection means 10 and the calculator 201 (S41). Specifically, the water level detection means 10 detects the water pressure or the like of the bath water in the bathtub 1, and the calculator 201 calculates the water level in the bathtub 1 based on the water pressure or the like. And if the water surface 20 in the bathtub 1 shown in FIG. 4 becomes 10 cm or more above the draft line 23, the control apparatus 12 will command the water supply source 9 to stop water supply. Thereby, since the distance of the water surface 20 in the bathtub 1 and the water line 23 can be detected automatically correctly, the supply amount of water can be reduced.

以上より、本実施の形態2では、水位検知手段10および演算器201により浴槽1内の水位を検知することで、実施の形態1のように水位検知手段10のみに基づいて水位を検知する場合よりも、正確に浴槽1内の水位を検知することができる。   As described above, in the second embodiment, when the water level in the bathtub 1 is detected by the water level detecting means 10 and the computing unit 201, the water level is detected based only on the water level detecting means 10 as in the first embodiment. The water level in the bathtub 1 can be detected more accurately.

また、演算器201にて水位の変化を連続的に計算可能であり、排水時の浴槽1の水位の変化率を計算可能である。そのため、洗浄第二工程(S30)において、浴槽アダプタ2より下に位置する浴水の排水速度を計算することにより、その浴水の排水を完了させるためにかかる時間をより正確に計算できるため、洗浄工程の時間を短縮することができる。   Further, the calculator 201 can continuously calculate the change in the water level, and can calculate the rate of change in the water level of the bathtub 1 during drainage. Therefore, in the second cleaning step (S30), by calculating the drainage speed of the bath water located below the bathtub adapter 2, the time required to complete drainage of the bath water can be calculated more accurately. The time for the cleaning process can be shortened.

なお、本実施の形態2においても、入浴後の浴槽1の壁面の汚れ付着量が軽微な場合は、洗浄第一工程(S40)の実施後に、浴槽1の壁面全体が洗浄されていることが確認できれば、流路切換工程(S20)および洗浄第二工程(S30)を省略してもよい。また、洗浄剤または添加剤を併用してもよい。このとき、浴槽1に手動で添加するか、自動供給装置を浴槽1、または、水配管4の任意の箇所に設置してもよい。   Even in the second embodiment, when the amount of dirt attached to the wall surface of the bathtub 1 after bathing is slight, the entire wall surface of the bathtub 1 may be cleaned after the first cleaning step (S40). If it can be confirmed, the flow path switching step (S20) and the second cleaning step (S30) may be omitted. Moreover, you may use a cleaning agent or an additive together. At this time, you may add to the bathtub 1 manually, or you may install an automatic supply apparatus in the arbitrary locations of the bathtub 1 or the water piping 4. FIG.

FIG. 17 is a schematic diagram showing the configuration of the cleaning apparatus according to the third embodiment.
In the third embodiment, a storage device 301 is provided between the arithmetic unit 201 and the control device 12 and is connected to the arithmetic unit 201 and the control device 12 through a signal line 202, respectively.

以下、本実施の形態3に係る洗浄装置の動作について説明する。
なお、本実施の形態3におけるフローチャートは、実施の形態2に係る図16と同様である。
本実施の形態3では、記憶装置301で入浴中の水位変化を記憶することにより、人が入った時の水位変化が測定できるため、汚染された浴槽1の壁面の範囲を把握することができる。そのため、浴槽1のサイズをもとに、洗浄第一工程(S40)において供給すべき水の量を正確に把握することができる。そのため、実施の形態2よりも、水供給量を削減することができる。また、入浴時の水面20の上下回数により、入浴した人数を推定でき、浴槽1に付着する汚れ量を推定することができる。そのため、洗浄時間の設定が可能となり、浴槽1を清潔に保つことができる。
Hereinafter, the operation of the cleaning apparatus according to the third embodiment will be described.
The flowchart in the third embodiment is the same as that in FIG. 16 according to the second embodiment.
In this Embodiment 3, since the water level change during bathing is memorize | stored in the memory | storage device 301, since the water level change when a person enters can be measured, the range of the wall surface of the contaminated bathtub 1 can be grasped | ascertained. . Therefore, it is possible to accurately grasp the amount of water to be supplied in the first cleaning step (S40) based on the size of the bathtub 1. Therefore, the amount of water supply can be reduced as compared with the second embodiment. Moreover, the number of people who took a bath can be estimated by the frequency | count of the up-and-down of the water surface 20 at the time of bathing, and the amount of dirt adhering to the bathtub 1 can be estimated. Therefore, the cleaning time can be set and the bathtub 1 can be kept clean.

また、入浴後の浴槽1の壁面の汚れ付着量が軽微な場合は、洗浄第一工程(S40)の実施後に、浴槽1の壁面全体が洗浄されていることが確認できれば、流路切換工程(S20)および洗浄第二工程(S30)を省略してもよい。また、洗浄剤または添加剤を併用してもよい。また、浴槽1に手動で添加するか、自動供給装置を浴槽1、または、水配管4の任意の箇所に設置してもよい。   Moreover, when the amount of dirt attached to the wall surface of the bathtub 1 after bathing is slight, if it can be confirmed that the entire wall surface of the bathtub 1 is cleaned after the first cleaning process (S40), the flow path switching process ( S20) and the second cleaning step (S30) may be omitted. Moreover, you may use a cleaning agent or an additive together. Moreover, you may add to the bathtub 1 manually, or you may install an automatic supply apparatus in the arbitrary locations of the bathtub 1 or the water piping 4. FIG.

実施の形態4.
以下、本実施の形態4について説明するが、実施の形態1〜実施の形態3と重複するものについては省略し、実施の形態1〜実施の形態3と同じ部分または相当する部分には同じ符号を付す。
図18は、本発明の実施の形態4に係る洗浄装置の構成を示す概略図である。
本実施の形態4では、水位検知手段10の代わりに、水面20の位置に加え、汚れ等を検知可能な検知装置401(例えば、超音波センサ、光電センサなど)を浴槽1に設置し、制御装置12および演算器201とそれぞれ信号線402で接続した構成である。
Embodiment 4 FIG.
Hereinafter, the fourth embodiment will be described. However, the same elements as those in the first to third embodiments are omitted, and the same or corresponding parts as those in the first to third embodiments are denoted by the same reference numerals. Is attached.
FIG. 18 is a schematic diagram showing a configuration of a cleaning apparatus according to Embodiment 4 of the present invention.
In the fourth embodiment, in place of the water level detection means 10, a detection device 401 (for example, an ultrasonic sensor, a photoelectric sensor, etc.) capable of detecting dirt and the like in addition to the position of the water surface 20 is installed in the bathtub 1 and controlled. In this configuration, the apparatus 12 and the arithmetic unit 201 are connected to each other through a signal line 402.

本実施の形態4では、水位検知手段10の代わりに、浴槽1に検知装置401を設置することで、浴槽1の水面20の変化を正確に測定できる。そのため、洗浄第二工程(S30)において、浴槽アダプタ2より下に位置する浴水の排水を正確に検知することができるため、洗浄第二工程(S30)の時間短縮が可能となる。また、浴槽1の汚れ程度が測定できるため、洗浄第一工程(S40)および洗浄第二工程(S30)の洗浄時間を、それぞれ汚れ付着量に応じて設定することができる。
なお、その他の本実施の形態4に係る洗浄装置の動作は、実施の形態3と同様である。
In the fourth embodiment, a change in the water surface 20 of the bathtub 1 can be accurately measured by installing the detection device 401 in the bathtub 1 instead of the water level detection means 10. Therefore, since the drainage of the bath water located below the bathtub adapter 2 can be accurately detected in the second cleaning step (S30), the time required for the second cleaning step (S30) can be shortened. Moreover, since the stain | pollution | contamination grade of the bathtub 1 can be measured, the washing | cleaning time of a washing | cleaning 1st process (S40) and a washing | cleaning 2nd process (S30) can be set according to each dirt adhesion amount.
The other operations of the cleaning apparatus according to the fourth embodiment are the same as those in the third embodiment.
