Description

本発明は、特に洗濯機等に使用する粉末洗剤の溶け残りを防止するとともに、高濃度洗剤液による洗剤の化学的洗浄力を有効に活用するために、予め粉末洗剤を少量の水で溶解できる高濃度の洗濯液を生成する洗剤溶解装置の構造に関するものである。   The present invention can dissolve powder detergent in a small amount of water in advance in order to prevent undissolved powder detergent used especially in washing machines and the like and to effectively use the chemical cleaning power of the detergent by the high concentration detergent solution. The present invention relates to a structure of a detergent dissolving apparatus that generates a high concentration washing liquid.

従来は、洗濯機等に使用する粉末洗剤は粉末のまま洗濯槽に投入されており、洗濯物の量に応じた洗濯水が洗濯槽に供給される過程で、ある程度溶解される。更に洗濯が開始した際のパルセータの攪拌・回転で更に溶解される。   Conventionally, a powder detergent used in a washing machine or the like is put into a washing tub as powder, and is dissolved to some extent in the process of supplying washing water according to the amount of laundry to the washing tub. Furthermore, it is further dissolved by stirring and rotating the pulsator when washing is started.

しかし、洗濯槽に供給される水が、例えば冬場の寒冷時には粉末洗剤が衣類に覆われて溶け難く、溶け残りの洗剤が付いたまま洗濯されてしまうことがある。また、粉末洗剤を多量の水で溶解するため、高濃度の洗剤液にならない。このため、衣類に付着した多目の汚れに高濃度の洗剤液を浸透させて、多目の汚れを分解するという洗浄方式を有効に活用できなかった。   However, when the water supplied to the washing tub is cold in winter, for example, the powder detergent is covered with clothes and hardly melts, and the detergent may be washed with the undissolved detergent attached. Further, since the powder detergent is dissolved in a large amount of water, it does not become a highly concentrated detergent solution. For this reason, it was not possible to effectively utilize a cleaning method in which a high-concentration detergent solution is infiltrated into multi-stains adhering to clothing to decompose multi-stains.

また、粉末洗剤を高濃度の洗剤液に生成する洗剤溶解装置としては、特開２００２−３６０９８１号公報（特許文献１）や特開２００３−０１０５９２号公報（特許文献２）、特開２００４―８２８２（特許文献３）が挙げることができる。   Moreover, as a detergent dissolution apparatus which produces | generates a powder detergent in a high concentration detergent liquid, Unexamined-Japanese-Patent No. 2002-360981 (patent document 1), Unexamined-Japanese-Patent No. 2003-010592 (patent document 2), and Unexamined-Japanese-Patent No. 2004-8282. (Patent Document 3) can be mentioned.

特開２００２−３６０９８１号公報（特許文献１）・特開２００３−０１０５９２号公報（特許文献２）及び特開２００４−８２８２公報（特許文献３）に記載された洗濯機等に搭載されている洗剤溶解装置では、洗剤溶解容器の底壁を貫通した駆動軸を設け、この駆動軸に撹拌翼が備わる。さらに、洗剤溶解容器と攪拌電動機は金属ベース板上に水平方向に並べた状態では配設し、前記攪拌電動機の駆動軸先端には駆動ピニオンを嵌着し、洗剤溶解容器の底壁の底面の上部には、軸封部材を配設するとともにその下側には駆動軸の振れを防止するための軸受を配設し、その中心に駆動軸を貫通させた反洗剤溶解部先端に従動プーリを嵌着させ、前記駆動ピニオンと従動プーリはタイミングベルトで連結されている構成が開示されている。   Detergents mounted on washing machines and the like described in JP-A-2002-360981 (Patent Document 1), JP-A-2003-010592 (Patent Document 2) and JP-A-2004-8282 (Patent Document 3) In the dissolution apparatus, a drive shaft that penetrates the bottom wall of the detergent dissolution container is provided, and the drive shaft is provided with a stirring blade. Further, the detergent dissolving container and the stirring motor are arranged in a state of being arranged horizontally on the metal base plate, and a driving pinion is fitted to the tip of the driving shaft of the stirring motor, and the bottom surface of the bottom wall of the detergent dissolving container is installed. A shaft sealing member is disposed at the upper portion, and a bearing for preventing the drive shaft from shaking is disposed below the shaft sealing member. A configuration is disclosed in which the drive pinion and the driven pulley are connected by a timing belt.

特許文献１・特許文献２及び特許文献３に記載された洗剤溶解装置では、前記駆動ピニオンと従動プーリはタイミングベルトで連結されているため、（１）使用する部品点数を多く必要としている。また、（２）使用部品点数が多いため、組立てにも時間がかかっていた。さらに、（３）洗剤溶解容器に隣接して攪拌用電動機が配設されているため設置スペースを大きくとる必要があった。   In the detergent dissolving apparatuses described in Patent Literature 1, Patent Literature 2 and Patent Literature 3, since the drive pinion and the driven pulley are connected by a timing belt, (1) a large number of parts are required. Further, (2) since the number of parts used is large, it takes time to assemble. Furthermore, (3) since the electric motor for stirring is disposed adjacent to the detergent dissolution container, it is necessary to increase the installation space.

本発明は、この様な従来技術による問題に鑑みてなされたもので、その目的は（１）使用する部品点数を極力少なくし、（２）部品コストを低減するとともに、製造に関わる組立て時間が短縮化され、（３）小型化された洗剤溶解装置を提供することにある。   The present invention has been made in view of such problems of the prior art, and its purpose is (1) reducing the number of parts to be used as much as possible, (2) reducing the cost of parts, and assembling time for manufacturing. The object is to provide a shortened and (3) miniaturized detergent dissolving apparatus.

本発明は、洗剤溶解容器と、この洗剤溶解容器内に回転自在に備わる攪拌翼と、この撹拌翼を回転駆動する駆動用電動機とを有する洗剤溶解装置において、洗剤溶解容器の底から上向きに***し、駆動用電動機を保持する筒状の電動機保持筒と、この電動機保持筒の上部に設けた円筒状の封止部材保持筒とを有し、攪拌翼は電動機保持筒の外周および封止部材保持筒の外周を覆う円筒状のカバー部と、封止部材保持筒の上側を覆う天井部と、天井部に設けられ、かつ駆動用電動機の回転軸に支持される軸支持ボス部とを有し、外周側が封止部材保持筒の内側に嵌合し、内周側が軸支持ボス部側に摺接する軸封止部材を有することを特徴とする。   The present invention relates to a detergent dissolution apparatus having a detergent dissolution container, a stirring blade rotatably provided in the detergent dissolution container, and an electric motor for driving the rotation of the stirring blade. And a cylindrical motor holding cylinder for holding the driving motor, and a cylindrical sealing member holding cylinder provided on the upper part of the motor holding cylinder, and the stirring blades are arranged on the outer periphery and the sealing member of the motor holding cylinder. A cylindrical cover portion covering the outer periphery of the holding cylinder, a ceiling portion covering the upper side of the sealing member holding cylinder, and a shaft support boss portion provided on the ceiling portion and supported by the rotating shaft of the driving motor. The outer peripheral side is fitted inside the sealing member holding cylinder, and the inner peripheral side has a shaft sealing member that is in sliding contact with the shaft support boss portion side.

本発明によれば、使用する部品点数を少なくし、部品コストを低減するとともに、製造に関わる組立て時間が短縮化され、小型化された洗剤溶解装置を提供できる。   ADVANTAGE OF THE INVENTION According to this invention, while reducing the number of components to use and reducing component cost, the assembly time concerning manufacture is shortened and the detergent melter reduced in size can be provided.

以下、本発明の実施例を図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

まず、図1〜図１２に沿って洗剤溶解装置の構造から順に説明する。   First, the structure of the detergent dissolving apparatus will be described in order from FIG. 1 to FIG.

洗剤溶解容器１は、底を形成する底壁部２のほぼ中央から上向きに***する筒状の電動機保持筒３と、この電動機保持筒３の上部に設けた円筒状の封止部材保持筒４とを有する。洗剤溶解容器１、電動機保持筒３、および封止部材保持筒４は合成樹脂により一体に形成する。   The detergent dissolution container 1 includes a cylindrical electric motor holding cylinder 3 that protrudes upward from substantially the center of the bottom wall portion 2 that forms the bottom, and a cylindrical sealing member holding cylinder 4 that is provided above the electric motor holding cylinder 3. And have. The detergent dissolution container 1, the electric motor holding cylinder 3, and the sealing member holding cylinder 4 are integrally formed of synthetic resin.

電動機保持筒３は、底壁部２の外底側にも延在した下側保持筒３ａを有する。この下側保持筒３ａと電動機保持筒３には、縦方向に延在する位置決めリブ５を設ける。   The electric motor holding cylinder 3 has a lower holding cylinder 3 a that extends to the outer bottom side of the bottom wall 2. The lower holding cylinder 3a and the motor holding cylinder 3 are provided with positioning ribs 5 extending in the vertical direction.

駆動用電動機６は、下側保持筒３ａの下開口から挿入されて電動機保持筒３に保持される。   The driving motor 6 is inserted from the lower opening of the lower holding cylinder 3 a and is held by the motor holding cylinder 3.

図６に示すように駆動用電動機６には、外周に金属環７が巻かれて固定される。金属環７の両端によってスリット８が形成される。このスリット８に位置決めリブ５が挿入するように嵌るので、駆動用電動機６は位置け決めが行なわれるとともに回り止めされるように保持される。   As shown in FIG. 6, a metal ring 7 is wound around the outer periphery of the drive motor 6 and fixed. A slit 8 is formed by both ends of the metal ring 7. Since the positioning ribs 5 are inserted into the slits 8, the drive motor 6 is positioned and held so as to be prevented from rotating.

駆動用電動機６は回転軸９を有する。回転軸９には、先端に図９に示す中間リング１３が支持される。この中間リング１３は外周側に回り止め用のローレット１３ａを有する。中間リング１３は、内周側を回転軸９の外周に圧入嵌合して固定される。   The drive motor 6 has a rotating shaft 9. An intermediate ring 13 shown in FIG. 9 is supported at the tip of the rotary shaft 9. The intermediate ring 13 has a knurl 13a for preventing rotation on the outer peripheral side. The intermediate ring 13 is fixed by press-fitting the inner peripheral side to the outer periphery of the rotary shaft 9.

駆動用電動機６により回転駆動される攪拌翼１０は、合成樹脂により形成される。攪拌翼１０は、図８に示すように、電動機保持筒３の外周および封止部材保持筒４の外周を覆う円筒状のカバー部１０ａと、封止部材保持筒４の上側を覆う天井部１０ｃと、天井部１０ｃに設けられ、かつ駆動用電動機６の回転軸９に支持される軸支持ボス部１０ｂとを有する。   The stirring blade 10 that is rotationally driven by the driving motor 6 is made of synthetic resin. As shown in FIG. 8, the stirring blade 10 includes a cylindrical cover portion 10 a that covers the outer periphery of the motor holding cylinder 3 and the outer periphery of the sealing member holding cylinder 4, and a ceiling portion 10 c that covers the upper side of the sealing member holding cylinder 4. And a shaft support boss portion 10b provided on the ceiling portion 10c and supported by the rotating shaft 9 of the drive motor 6.

軸支持ボス部１０ｂは、外周に金属の軸リング１５を有する。軸リング１５は軸支持ボス部１０ｂと一体に形成される。   The shaft support boss 10b has a metal shaft ring 15 on the outer periphery. The shaft ring 15 is formed integrally with the shaft support boss portion 10b.

中間リング１３は、軸支持ボス部１０ｂの軸支持穴に圧入される。回り止め用のローレット１３ａにより、中間リング１３は軸支持ボス部１０ｂにしっかり結合される。軸支持ボス部１０ｂの外周に金属の軸リング１５が設けられているので、中間リング１３の強い圧入に耐え、より強い結合が期待できる。   The intermediate ring 13 is press-fitted into the shaft support hole of the shaft support boss 10b. The intermediate ring 13 is firmly coupled to the shaft support boss portion 10b by a knurl 13a for preventing rotation. Since the metal shaft ring 15 is provided on the outer periphery of the shaft support boss 10b, it can withstand strong press-fitting of the intermediate ring 13 and a stronger coupling can be expected.

攪拌翼１０を撹拌回転して洗剤を溶解する。洗剤溶解液の粘性が強いので、駆動用電動機６に反力が生ずる。しかし、前述したように、電動機保持筒３の位置決めリブ５と駆動用電動機６のスリット８との係合により、駆動用電動機６は回ることなく保持されるのである。また、電源と接続させるリード線１１（図７に図示）を取り付ける駆動電動機６の端子１２の方向も常に同一方向にすることが可能となる。   The detergent blade is dissolved by rotating the stirring blade 10 with stirring. Since the detergent solution has a high viscosity, a reaction force is generated in the drive motor 6. However, as described above, due to the engagement between the positioning rib 5 of the motor holding cylinder 3 and the slit 8 of the driving motor 6, the driving motor 6 is held without rotating. Further, the direction of the terminal 12 of the drive motor 6 to which the lead wire 11 (shown in FIG. 7) to be connected to the power source is attached can always be the same direction.

図６に示す軸封止部材１４は、円環状の形を有し、かつゴムで形成されている。この軸封止部材１４は、図１、図７に示すように、封止部材保持筒４に保持される。軸封止部材１４は、外周１４ａが封止部材保持筒４の内側に嵌合し、内周１４ｂが軸支持ボス部１０ｂの軸リング１５に摺接する。   The shaft sealing member 14 shown in FIG. 6 has an annular shape and is made of rubber. The shaft sealing member 14 is held by the sealing member holding cylinder 4 as shown in FIGS. As for the shaft sealing member 14, the outer periphery 14a fits inside the sealing member holding | maintenance cylinder 4, and the inner periphery 14b is slidably contacted with the shaft ring 15 of the shaft support boss | hub part 10b.

この軸封止部材１４による封止により、駆動用電動機６に洗剤溶解液が流入するのが阻止される。   The sealing by the shaft sealing member 14 prevents the detergent solution from flowing into the driving motor 6.

また、軸封止部材１４の内周１４ｂが摺接する軸リング１５は、金属で形成されているので、軸支持ボス部１０ｂに中間リング１３の圧入に耐えて外径が径大になる膨らみが抑えられる。これにより、軸封止部材１４の内周１４ｂと軸リング１５との摺接状態が変化することなく一定に保たれるので、良好な軸封が維持される。   Further, since the shaft ring 15 with which the inner periphery 14b of the shaft sealing member 14 is in sliding contact is formed of metal, the shaft support boss portion 10b has a bulge that can withstand the press-fitting of the intermediate ring 13 and the outer diameter increases. It can be suppressed. Thereby, since the sliding contact state of the inner periphery 14b of the shaft sealing member 14 and the shaft ring 15 is kept constant without changing, a good shaft seal is maintained.

また、洗剤溶解液が軸封止部材側に流れ込み難い構造になっている。   Further, the detergent solution is difficult to flow into the shaft sealing member side.

すなわち、攪拌翼１０は、電動機保持筒３の外周および封止部材保持筒４の外周をカバー部１０ａで覆うとともに封止部材保持筒４の上側を天井部１０ｃで覆っている。しかも、攪拌翼１０と電動機保持筒３との間は、狭い間隙のラビリンス構成になっている。   That is, the stirring blade 10 covers the outer periphery of the electric motor holding cylinder 3 and the outer periphery of the sealing member holding cylinder 4 with the cover part 10a and the upper side of the sealing member holding cylinder 4 with the ceiling part 10c. Moreover, a labyrinth structure with a narrow gap is provided between the stirring blade 10 and the motor holding cylinder 3.

このため、洗剤溶解液が攪拌翼１０と電動機保持筒３との間に流れ込んでもラビリンス構成の中に溜まる空気の層に阻まれて洗剤溶解液は狭い間隙の奥深くまで流れ込むことができない。このように洗剤溶解液の流入は、狭い間隙のラビリンス構成により阻止されるので、軸封止部材１４のところに洗剤溶解液が達することは通常は生じないのである。   For this reason, even if the detergent solution flows between the stirring blade 10 and the electric motor holding cylinder 3, the detergent solution cannot flow deep into the narrow gap due to the air layer accumulated in the labyrinth structure. As described above, since the inflow of the detergent solution is blocked by the labyrinth structure having a narrow gap, the detergent solution does not normally reach the shaft sealing member 14.

図１、図６、図７に示すように、洗剤溶解容器１の下面には、電動機保持筒３に挿入保持された駆動用電動機６を下側から抑える電動機カバー１６（脱落防止兼固定部材）が取り付けられる。この電動機カバー１６は、下側保持筒３ａの外周に嵌合するように取り付けられ、洗剤溶解容器１の下面に設けたボス部１７に複数本の螺子１８を螺合して締め付けられる。   As shown in FIGS. 1, 6, and 7, on the lower surface of the detergent dissolution container 1, an electric motor cover 16 (drop-off prevention and fixing member) that holds the driving electric motor 6 inserted and held in the electric motor holding cylinder 3 from below. Is attached. The motor cover 16 is attached so as to be fitted to the outer periphery of the lower holding cylinder 3a, and is tightened by screwing a plurality of screws 18 to a boss portion 17 provided on the lower surface of the detergent dissolution container 1.

洗剤溶解容器１の下側には、図６に示すシャワーカバー１９が図１、図７に示すように取り付けられる。シャワーカバー１９は、高濃度に溶解した洗剤溶解液を洗濯槽内（図示せず）の衣類にまんべんなく散布する複数の開口部１９ａを有する。   A shower cover 19 shown in FIG. 6 is attached to the lower side of the detergent dissolution container 1 as shown in FIGS. The shower cover 19 has a plurality of openings 19a for evenly spraying the detergent solution dissolved in a high concentration on clothes in a washing tub (not shown).

洗剤溶解容器１とシャワーカバー１９は、洗剤溶解容器１の下端周縁に設けた凸部２１と、シャワーカバー１９の上端周縁に設けた凹溝２２との嵌合により合わせられる。凸部２１と凹溝２２の嵌合部には、複数本の金属線２３を介在する。この金属線２３を通電加熱することにより、合成樹脂で形成された洗剤溶解容器１とシャワーカバー１９の嵌合部が熱溶着される。   The detergent dissolution container 1 and the shower cover 19 are fitted together by fitting a convex portion 21 provided at the lower peripheral edge of the detergent dissolution container 1 and a concave groove 22 provided at the upper peripheral edge of the shower cover 19. A plurality of metal wires 23 are interposed in the fitting portion between the convex portion 21 and the concave groove 22. By electrically energizing and heating the metal wire 23, the fitting portion between the detergent dissolution container 1 and the shower cover 19 formed of synthetic resin is thermally welded.

この熱溶着により、洗剤溶解容器１とシャワーカバー１９の嵌合部は、水密が保たれた丈夫な結合となる。   By this thermal welding, the fitting portion between the detergent dissolution container 1 and the shower cover 19 becomes a strong bond with watertightness maintained.

図７に示す水投入部材４８は、図１０に示すように洗剤溶解容器１の上部に設けられる。この水投入部材４８は、図１１、図１２に示すように、洗剤溶解容器１内の粉末洗剤を溶く水が注がれる溶解水注ぎ口６０を有する。溶解水注ぎ口６０は、水投入部材４８の先端側に設けられ、横方向に延びた横長形状を有する。   The water input member 48 shown in FIG. 7 is provided in the upper part of the detergent dissolution container 1 as shown in FIG. As shown in FIGS. 11 and 12, the water charging member 48 has a dissolved water spout 60 into which water for dissolving the powder detergent in the detergent dissolution container 1 is poured. The dissolved water pouring spout 60 is provided on the front end side of the water charging member 48 and has a horizontally long shape extending in the horizontal direction.

水投入部材４８の背後側には、注水管（図示せず）の接続口６１が設けられる。この接続口６１は、溶解水注ぎ口６０に連通している。水投入部材４８は、上下に合わさる二つの水投入部材片より形成される。上下に合わせ部は、前述した洗剤溶解容器とシャワーカバーと同様に金属線を用いて熱溶着する。   A connection port 61 for a water injection pipe (not shown) is provided behind the water injection member 48. The connection port 61 communicates with the dissolved water pouring port 60. The water input member 48 is formed of two water input member pieces that are aligned vertically. The upper and lower mating portions are thermally welded using a metal wire in the same manner as the detergent dissolution container and the shower cover described above.

水投入部材４８は、ネジ４９を用いて洗剤溶解容器１に着脱自在に取り付けられる。水投入部材４８の先端側が洗剤溶解容器１内に突き出るように取り付けるので、溶解する水を洗剤溶解容器１内の中央寄りに注水できる。このため、洗剤溶解容器１内の粉末洗剤に溶解水が行渡り易い。また、溶解水注ぎ口６０が横長形状になっているので、溶解水を広範囲に降り注ぐことができ、粉末洗剤の溶解が促進され易い。   The water charging member 48 is detachably attached to the detergent dissolution container 1 using screws 49. Since the tip side of the water injection member 48 is attached so as to protrude into the detergent dissolution container 1, the water to be dissolved can be poured toward the center of the detergent dissolution container 1. For this reason, the dissolved water easily reaches the powder detergent in the detergent dissolution container 1. Moreover, since the dissolved water pouring spout 60 has a horizontally long shape, the dissolved water can be poured over a wide range, and the dissolution of the powder detergent is easily promoted.

洗剤溶解液の液面２６は、図７に示すように軸封止部材１４より低くすることが望ましい。洗剤溶解液は狭い間隙の奥深くまで流れ込んでも軸封止部材１４に達しないからである。   The liquid surface 26 of the detergent solution is desirably lower than the shaft sealing member 14 as shown in FIG. This is because the detergent solution does not reach the shaft sealing member 14 even if it flows deep into the narrow gap.

攪拌翼１０の撹拌回転時には、洗剤溶解液の液面がすり鉢状液面２７になる。洗剤溶解容器１の中心部液面が低くなり、撹拌回転時には洗剤溶解液が軸封止部材１４に流れ込むようなことは生じない。   During the stirring rotation of the stirring blade 10, the liquid level of the detergent solution becomes the mortar-shaped liquid level 27. The liquid level of the central portion of the detergent dissolution container 1 is lowered, and the detergent solution does not flow into the shaft sealing member 14 during the rotation of stirring.

粉末洗剤には通常、ゼオライトと言う軟水化成分が含まれる。このゼオライトは研磨剤の役割も持っており、例えば攪拌翼１０の金属部１５とゴム製の軸封止部材１４の封止部に入り込んだ状態で回転されると、その封止部が磨耗して、漏水する場合がある。   A powder detergent usually contains a water softening component called zeolite. The zeolite also serves as an abrasive. For example, when the zeolite is rotated while entering the sealing portion of the metal portion 15 of the stirring blade 10 and the rubber shaft sealing member 14, the sealing portion is worn. May leak.

しかし、撹拌回転前に軸封止部材１４より低くかった液面２６は、撹拌回転時には中心部液面がさらに低くなるので、軸封止部材１４に洗剤溶解液が流れ込むのを皆無に抑えることができる。   However, since the liquid level 26 that was lower than the shaft sealing member 14 before the rotation of stirring is lower than that of the central portion during the rotation of stirring, the detergent solution does not flow into the shaft sealing member 14 at all. Can do.

洗剤溶解容器１内には、水投入部材４８の反対側の位置に溢水口７０が設けられる。この溢水口７０の下方にシャワーカバー１９の開口部１９ａが位置している。溢水口７０は図１３に示すように水投入部材４８より低い高さ位置に設けている。溢水は、溢水口７０から開口部１９ａに流する。水投入部材４８を越えて溢水は生じない。   In the detergent dissolution container 1, an overflow port 70 is provided at a position opposite to the water charging member 48. An opening 19 a of the shower cover 19 is located below the overflow port 70. As shown in FIG. 13, the overflow port 70 is provided at a lower position than the water charging member 48. The overflow flows from the overflow port 70 to the opening 19a. Overflow does not occur beyond the water input member 48.

洗剤溶解容器１には、溢水口７０側の側面に開口部５２が設けられる。開口部５２は溢水口７０、開口部１９ａに通じている。冬季に開口部５２が凍結しても、開口部５２から溢水等を排水することができる。   The detergent dissolution container 1 is provided with an opening 52 on the side surface on the overflow port 70 side. The opening 52 communicates with the overflow port 70 and the opening 19a. Even if the opening 52 is frozen in the winter, overflow water or the like can be drained from the opening 52.

洗剤溶解容器１内には、図１０に示すようにサイホン機構７１を有する。サイホン機構７１は外管７２と内管７３を有する。洗剤溶解容器１内に溜まる水位が内管７３の上端を越えると、洗剤溶解容器１の水は内管７３を下ってシャワーカバー１９内に流出する。洗剤溶解容器１の水位が下がり、外管７２の下部の吸込口が大気に開口まで流出は行なわれる。   The detergent dissolution container 1 has a siphon mechanism 71 as shown in FIG. The siphon mechanism 71 has an outer tube 72 and an inner tube 73. When the water level accumulated in the detergent dissolution container 1 exceeds the upper end of the inner pipe 73, the water in the detergent dissolution container 1 flows down the inner pipe 73 and into the shower cover 19. The water level of the detergent dissolution container 1 is lowered, and the suction port at the lower part of the outer pipe 72 is discharged to the atmosphere.

洗剤溶解容器１内で生成された洗剤溶解液は、サイホン機構７１を介してシャワーカバー１９に排出される。   The detergent solution generated in the detergent dissolution container 1 is discharged to the shower cover 19 via the siphon mechanism 71.

すなわち、撹拌翼１０の撹拌回転により、洗剤溶解液が生成されたら水投入部材４８を水を注ぐ。注水はサイホン機構７１がサイホン作用するところまで行なう。サイホン作用により、生成された洗剤溶解液は排出される。   That is, when the detergent solution is generated by the stirring rotation of the stirring blade 10, water is poured into the water charging member 48. Water injection is performed until the siphon mechanism 71 is siphoned. The generated detergent solution is discharged by siphon action.

サイホン機構７１の内管７３の上端は、溢水口７０より高さＨだけ低くなっているので、溢水口７０から排水する前にサイホン作用が発生し、生成した洗剤溶解液を全部排出することができる。   Since the upper end of the inner pipe 73 of the siphon mechanism 71 is lower than the overflow port 70 by a height H, a siphon action occurs before draining from the overflow port 70, and all the generated detergent solution can be discharged. it can.

サイホン機構７１が詰まって洗剤溶解容器１内の水位が増すと、前述した溢水口７０から逸す溢水が行なわれるので、生成した洗剤溶解液が水投入部材４８を越えて溢水したり、洗剤溶解容器１の上縁部より溢れでることがない。   When the siphon mechanism 71 is clogged and the water level in the detergent dissolving container 1 is increased, overflowing from the overflow port 70 is performed, so that the generated detergent dissolving liquid overflows the water input member 48 or the detergent dissolving container No overflow from the upper edge of 1.
