Description

本発明は、トイレルーム内に設置された手洗い器に取り付けられる水はね防止具に関し、例えば、水洗トイレの水タンク上部に設けられた手洗い器に装着することにより、手洗いの際に手洗い器の周囲に水が飛散するのを防止する水はね防止具に関する。 The present invention relates to a water splash prevention device attached to a hand-washer installed in a toilet room, for example, by attaching it to a hand-washer provided above a water tank of a water-washing toilet, The present invention relates to a water splash prevention device for preventing water from splashing around.

近年、住宅用トイレなどにおいては、水洗トイレの給水タンク上部や、トイレルーム内の側壁、サイドカウンター等に手洗い器が設けられている。このような手洗い器は、通常、手洗い水が吐出する水栓と、手洗い水を流すためのボウルを備えている。ところが、トイレルーム内の手洗い器では、手洗い時に水滴が周囲に飛び散り、便座やトイレルームの床・壁、使用者の衣服などが濡れてしまうという問題があった。 In recent years, in toilets for homes, hand-washing devices are provided in the upper part of the water supply tank of the flush toilet, the side walls in the toilet room, the side counter, and the like. Such a hand-washing machine is normally provided with a faucet for discharging hand-washing water and a bowl for flowing hand-washing water. However, the hand-washing machine in the toilet room has a problem in that water drops are scattered around when washing the hand, and the toilet seat, the floor / wall of the toilet room, and the clothes of the user get wet.

そこで従来より、水はね防止具として、特許文献１のように、給水タンクの前面に蛇腹状に開閉可能な水はねガードを設けたり、特許文献２のように、手洗い器のボウル背面にガードパネルを設けたりした手洗い器が提案されている。また、特許文献３のように、ボウルを奥行きが狭く深い形状とすることにより、手洗い水の飛散を抑えた手洗い器も提案されている。 Therefore, conventionally, as a water splash prevention tool, a water splash guard that can be opened and closed like a bellows is provided on the front surface of the water supply tank as in Patent Document 1, or on the back surface of a bowl of a hand-washer as in Patent Document 2. Hand washing machines with guard panels have been proposed. In addition, as in Patent Document 3, a hand-washing machine has been proposed in which the bowl has a narrow and deep shape, thereby suppressing the scattering of hand-washing water.

しかしながら、従来の水はね防止具は、例えば、特許文献１の手洗い装置は、大掛かりな装置を別置きする構成となっており、既存のトイレに簡単に設置できるようにはなっていない。また、特許文献２の手洗い器は、側壁など背後への水はねは防止できるものの、前面側への水はねは防止できず、使用者や便座、床などへの水濡れは避けられない。特に、便座の水濡れは、次のトイレ使用者に多大な不快感を与えるため、その回避が求められる。この場合、便座を起こし便座ふたと共に立て掛けた状態としても、便座と便座ふたの間に手洗い器から飛散した水が入り込み、便座が濡れてしまうおそれがある。このため、便座の濡れを防止するには、便器側への水はね自体を抑止する必要がある。一方、特許文献３の手洗い器は、深いボウル内にて手を洗うため、ボウル外への水はねを抑えることが可能ではあるものの、給水タンク上部には形成しにくく、既存のトイレには後付けできない。 However, as for the conventional water splash prevention tool, for example, the hand-washing apparatus of Patent Document 1 has a configuration in which a large-scale apparatus is separately provided, and cannot be easily installed in an existing toilet. Moreover, although the hand-washing machine of patent document 2 can prevent the water splashing to the back, such as a side wall, it cannot prevent the water splashing to the front side, and the wetness to a user, a toilet seat, a floor, etc. cannot be avoided. . In particular, the wetness of the toilet seat gives great discomfort to the next toilet user. In this case, even when the toilet seat is raised and stood with the toilet seat lid, water scattered from the hand-washing device may enter between the toilet seat and the toilet seat lid, and the toilet seat may get wet. For this reason, in order to prevent the toilet seat from getting wet, it is necessary to suppress water splashing to the toilet side itself. On the other hand, the hand-washing machine of Patent Document 3 washes hands in a deep bowl, so that it is possible to suppress water splashing outside the bowl, but it is difficult to form on the upper part of the water supply tank. Can't be retrofitted.

本発明の目的は、手洗い時の水飛沫により、トイレルームの床や壁、使用者の衣服などが濡れてしまうのを防止でき、しかも、トイレルーム内の既存の手洗い器にも設置可能な水はね防止具を提供することにある。 The object of the present invention is to prevent the floor and walls of the toilet room and the clothes of the user from getting wet due to water splashes during hand washing, and water that can be installed in an existing hand washing machine in the toilet room.

The water splash preventing device 1 is installed in a hand-washing device 2 provided in the toilet room. As shown in FIG. 1, the water splash prevention tool 1 of the said Example is attached to the hand-washing machine 2 provided in the upper part of the water supply tank 3 of the flush toilet. The total height X of the water splash preventing tool 1 (see FIG. 3B) is higher than the depth of the bowl portion 4 (approximately about 2 to 3 times).

手洗い器２は、手洗い用のボウル部４と、手洗い水が吐出する水栓５と、ボウル部４内の水を排水する排水口６を備えている。ボウル部４は、給水タンク３の上部に載置されるタンク上蓋７の上面側に凹設されている。ボウル部４の内側は、排水口６に向かって下る曲面状の斜面となっている。水栓５は、ボウル部４の使用者側から見て奥側から、ボウル部４の中心側に向かって伸びており、上方に向かって斜めに延びる導水管８を備えている。導水管８の先端には、下方に開口する吐水口９が設けられている。排水口６は、ボウル部４の中心最深部に開口形成されている。タンク上蓋７を給水タンク本体１１上に載置すると、排水口６はタンク本体１１内の空間と連通する。 The hand-washing machine 2 includes a hand-washing bowl portion 4, a faucet 5 from which hand-washing water is discharged, and a drain port 6 that drains the water in the bowl portion 4. The bowl portion 4 is recessed on the upper surface side of the tank upper lid 7 placed on the upper portion of the water supply tank 3. The inside of the bowl portion 4 is a curved slope that goes down toward the drain port 6. The faucet 5 includes a water conduit 8 that extends from the back side toward the center side of the bowl portion 4 as viewed from the user side of the bowl portion 4 and extends obliquely upward. A water outlet 9 that opens downward is provided at the tip of the water conduit 8. The drain port 6 is formed as an opening at the deepest center of the bowl portion 4. When the tank upper lid 7 is placed on the water supply tank main body 11, the drainage port 6 communicates with the space in the tank main body 11.

給水タンク本体１１の側面には、フラッシュレバー１２が取り付けられている。フラッシュレバー１２を操作すると、吐水口９から手洗水が流出する。吐水口９から流出した手洗い水は、使用者の手洗いに供された後、ボウル部４内に流れ、排水口６から給水タンク本体１１内へと排出される。給水タンク本体１１内に流入した水は、フラッシュレバー１２の操作に伴い、適宜、便器１３の洗浄に使用される。 A flash lever 12 is attached to the side surface of the water supply tank body 11. When the flash lever 12 is operated, hand wash water flows out from the water outlet 9. The hand-washing water that has flowed out from the spout 9 is supplied to the user's hand, and then flows into the bowl portion 4 and is discharged from the drain 6 into the water supply tank body 11. The water that has flowed into the water supply tank body 11 is used for washing the toilet bowl 13 as the flash lever 12 is operated.

水はね防止具１は、図１〜５に示すように、凹面状の内面を有する水受ボウル２１によって形成されている。水受ボウル２１は、手洗い器２のボウル部４と略同形の椀状となっている。水受ボウル２１には、曲面状の前壁部２１ａ・側壁部２１ｂ,２１ｃ・奥壁部２１ｄと、略平面状の底面部２１ｅが設けられている。水受ボウル２１は、合成樹脂材料を用いて一体に成型されており、前壁部２１ａと側壁部２１ｂ,２１ｃ、奥壁部２１ｄ、底面部２１ｅは、継ぎ目なく連続的に形成されている。水受ボウル２１の材料としては、例えば、透明なＰＥＴ（ポリエチレンテレフタレート）や塩化ビニル等の合成樹脂が用いられる。 As shown in FIGS. 1 to 5, the water splash preventing tool 1 is formed by a water receiving bowl 21 having a concave inner surface. The water receiving bowl 21 has a bowl shape substantially the same shape as the bowl portion 4 of the hand-washing machine 2. The water receiving bowl 21 is provided with a curved front wall portion 21a, side wall portions 21b and 21c, a back wall portion 21d, and a substantially flat bottom surface portion 21e. The water receiving bowl 21 is integrally molded using a synthetic resin material, and the front wall portion 21a, the side wall portions 21b and 21c, the back wall portion 21d, and the bottom surface portion 21e are continuously formed without a seam. As a material of the water receiving bowl 21, for example, a synthetic resin such as transparent PET (polyethylene terephthalate) or vinyl chloride is used.

奥壁部２１ｄの中央部やや下方には、水栓５が挿通される水栓孔２２が開口形成されている。水はね防止具１は、この水栓孔２２に導水管８を挿通することにより、図１に示すように、ボウル部４上に取り付けられる。水受ボウル２１の底面部２１ｅには、排水孔２３が形成されている。排水孔２３の裏面側（ボウル部４と対向する面側）には、外側に向かって突出するガイドボス２４が形成されている。 A faucet hole 22 through which the faucet 5 is inserted is formed slightly below the central portion of the rear wall portion 21d. The water splash preventing device 1 is attached on the bowl portion 4 as shown in FIG. 1 by inserting the water conduit 8 into the faucet hole 22. A drain hole 23 is formed in the bottom surface portion 21 e of the water receiving bowl 21. A guide boss 24 that protrudes outward is formed on the back side of the drain hole 23 (the side facing the bowl portion 4).

ガイドボス２４の外径は、排水口６の内径よりも小径に形成されている。ボウル部４上に水はね防止具１を取り付けると、排水孔２３は排水口６の上方に配される。その際、ガイドボス２４は排水口６内に挿入され、ガイドボス２４は排水口６内に遊嵌状態で挿入される。このように、ガイドボス２４を排水口６内に挿入すると、水はね防止具１は、水栓孔２２（導水管８が挿通）と、ガイドボス２４の２箇所で移動が規制される。従って、水はね防止具１が導水管８を中心に回転することがなく、水はね防止具１は、ボウル部４上に安定的に載置される。 The outer diameter of the guide boss 24 is smaller than the inner diameter of the drain port 6. When the water splash preventing tool 1 is attached on the bowl portion 4, the drain hole 23 is disposed above the drain port 6. At that time, the guide boss 24 is inserted into the drain port 6, and the guide boss 24 is inserted into the drain port 6 in a loosely fitted state. As described above, when the guide boss 24 is inserted into the drain outlet 6, the movement of the water splash preventing device 1 is restricted at the two positions of the faucet hole 22 (the water conduit 8 is inserted) and the guide boss 24. Therefore, the water splash preventing device 1 does not rotate around the water conduit 8, and the water splash preventing device 1 is stably placed on the bowl portion 4.

奥壁部２１ｄにはまた、２つの貫通孔２５が形成されている。貫通孔２５は、水栓孔２２の両側にそれぞれ形成されており、各貫通孔２５は、水栓孔２２から水受ボウル２１の幅方向にほぼ等間隔の位置に開口している。貫通孔２５は、水受ボウル２１を安定させるために設けられており、万一、水受ボウル２１の取付状態が安定しない場合には、図２に示すように、貫通孔２５に紐２６の一端を結びつける。そして、トイレルームの壁面などに紐２６の他端を固定することにより、水受ボウル２１の揺れ動きを抑制し、より安定的に水はね防止具１をボウル部４上に取り付けることが可能となる。 Two through holes 25 are also formed in the back wall portion 21d. The through holes 25 are respectively formed on both sides of the faucet hole 22, and each through hole 25 opens from the faucet hole 22 at substantially equal intervals in the width direction of the water receiving bowl 21. The through hole 25 is provided to stabilize the water receiving bowl 21. If the mounting state of the water receiving bowl 21 is not stable, as shown in FIG. Tie one end. And, by fixing the other end of the string 26 to the wall surface of the toilet room, etc., the swinging movement of the water receiving bowl 21 can be suppressed, and the water splash preventing tool 1 can be mounted on the bowl portion 4 more stably. Become.

水受ボウル２１には、球面状のボス（凸部）３３が複数個形成されている。ボス３３は水受ボウル２１の裏面側に突設されており、外方に向かって突出している。ボス３３は、底面部２１ｅの手前側に２個、奥側に１個設けられている。ボウル部４に水はね防止具１を取り付けると、ボス３３の頂部が、ボウル部４の水受面（内面）４ａに対向・当接し、ボウル部４と水はね防止具１との間に隙間４６が形成される。このように、水はね防止具１では、全体がボウル部４と密着せず、両者間に隙間４６が形成されるため、水はね防止具１とボウル部４との間に水が流れ込んでも、その水は支障なく排水口６に流出する。また、水はね防止具１とボウル部４との間に隙間４６が存在するため、両者間に空気が流通し、ボウル部４や水はね防止具１が容易に乾燥する。従って、ボウル部４や水はね防止具１に発生するカビやヌメリ、変色などを防止でき、掃除の手間が掛からず、衛生状態も良好に保たれる。 A plurality of spherical bosses (convex portions) 33 are formed on the water receiving bowl 21. The boss 33 protrudes from the back side of the water receiving bowl 21 and protrudes outward. Two bosses 33 are provided on the front side of the bottom surface portion 21e and one on the back side. When the water splash preventing device 1 is attached to the bowl portion 4, the top of the boss 33 faces and abuts against the water receiving surface (inner surface) 4 a of the bowl portion 4, and between the bowl portion 4 and the water splash preventing device 1. A gap 46 is formed in the gap. In this way, the water splash prevention tool 1 does not adhere to the bowl part 4 as a whole, and a gap 46 is formed between them, so that water flows between the water splash prevention tool 1 and the bowl part 4. However, the water flows out into the drain 6 without any trouble. Moreover, since the clearance gap 46 exists between the water splash prevention tool 1 and the bowl part 4, air distribute | circulates between both and the bowl part 4 and the water splash prevention tool 1 dry easily. Therefore, mold, slime, discoloration and the like generated in the bowl portion 4 and the water splash preventing device 1 can be prevented, and it does not take time for cleaning, and the hygienic state is maintained well.

水受ボウル２１にはさらに、石鹸入れ（石鹸収容部）３４が形成されている。石鹸入れ３４は、水栓孔２２の向かって右側、すなわち、奥壁部２１ｄの右端側に突設されている。石鹸入れ３４は、周壁部３５に取り囲まれた四角形状となっており、周壁部３５の内側は、石鹸を収容するための凹部３６となっている。周壁部３５の上縁部３５ａは、逆Ｕ字形に折り曲げられた曲面状に形成されており、利用者が石鹸入れ３４の上端縁にぶつかっても、利用者が不快感を抱かないようになっている。周壁部３５の手前側には、排水用のスリット３７が形成されている。凹部３６は、図５に示すように、手前側に向かって下方に傾斜しており、石鹸入れ３４内に溜まった水は、スリット３７から排出される。なお、石鹸入れ３４の形状は四角形には限定されず、円形やハート形など、意匠的な観点も含め適宜変更可能である。 The water receiving bowl 21 is further formed with a soap container (soap container) 34. The soap bowl 34 protrudes on the right side of the faucet hole 22, that is, on the right end side of the rear wall portion 21d. The soap bowl 34 has a quadrangular shape surrounded by the peripheral wall portion 35, and the inside of the peripheral wall portion 35 is a concave portion 36 for containing soap. The upper edge portion 35a of the peripheral wall portion 35 is formed in a curved shape bent in an inverted U shape, so that even if the user hits the upper edge of the soap bowl 34, the user will not feel uncomfortable. ing. A drainage slit 37 is formed on the front side of the peripheral wall portion 35. As shown in FIG. 5, the recess 36 is inclined downward toward the front side, and the water accumulated in the soap bowl 34 is discharged from the slit 37. The shape of the soap bowl 34 is not limited to a quadrangle, and can be appropriately changed including a design viewpoint such as a circle or a heart shape.

水受ボウル２１の上端部には、合成樹脂製のエッジカバー（カバー部材）４１が取り付けられている。図４は、エッジカバー４１の取付構造を示す説明図であり、（ａ）はその正面図、（ｂ）は（ａ）のＡ−Ａ線に沿った断面図である。エッジカバー４１は、塩化ビニルのような柔軟性のある合成樹脂にて形成されており、例えば、半透明な水色に着色されている。図４に示すように、エッジカバー４１は断面が略Ｕ字形となっており、その中央には装着溝（溝部）４２が形成されている。エッジカバー４１は、水受ボウル２１の上縁部４３を装着溝４２に挿入する形で、水受ボウル２１の上端部に装着される。なお、エッジカバー４１の透明度や色彩は、前述の「半透明／水色」には限定されず、不透明や他の色彩（例えば、赤や黄色など）とすることも可能である。 A synthetic resin edge cover (cover member) 41 is attached to the upper end of the water receiving bowl 21. 4A and 4B are explanatory views showing the mounting structure of the edge cover 41, in which FIG. 4A is a front view thereof, and FIG. 4B is a cross-sectional view taken along line AA in FIG. The edge cover 41 is formed of a flexible synthetic resin such as vinyl chloride, and is colored, for example, translucent light blue. As shown in FIG. 4, the edge cover 41 has a substantially U-shaped cross section, and a mounting groove (groove portion) 42 is formed at the center thereof. The edge cover 41 is attached to the upper end portion of the water receiving bowl 21 by inserting the upper edge portion 43 of the water receiving bowl 21 into the attachment groove 42. The transparency and color of the edge cover 41 are not limited to the above-mentioned “semi-transparent / light blue”, and may be opaque or other colors (for example, red or yellow).

水受ボウル２１の上縁部４３には、長手方向に沿って、テープ挿入孔４４が複数個形成されている。テープ挿入孔４４は、エッジカバー脱落防止用のテープ４５を取り付けるために設けられている。テープ挿入孔４４には、エッジカバー４１を上縁部４３に装着した状態でテープ４５が取り付けられる。そして、テープ４５をテープ挿入孔４４に挿入しつつエッジカバー４１に複数回巻き付けることにより、エッジカバー４１は、水受ボウル２１の上縁部４３を挟持しつつ、水受ボウル２１の上端部に固定される。なお、図４（ｂ）では、理解を容易にするため、テープ４５の厚みを誇張して示している。また、同図では、テープ４５が１回巻装されている様子が示されているが、実際は、テープ４５を複数回巻装することが好ましい。 A plurality of tape insertion holes 44 are formed in the upper edge portion 43 of the water receiving bowl 21 along the longitudinal direction. The tape insertion hole 44 is provided for attaching the tape 45 for preventing the edge cover from falling off. The tape 45 is attached to the tape insertion hole 44 in a state where the edge cover 41 is attached to the upper edge portion 43. Then, by winding the tape 45 around the edge cover 41 a plurality of times while inserting the tape 45 into the tape insertion hole 44, the edge cover 41 sandwiches the upper edge portion 43 of the water receiving bowl 21 and is attached to the upper end portion of the water receiving bowl 21. Fixed. In FIG. 4B, the thickness of the tape 45 is exaggerated for easy understanding. Moreover, although the state in which the tape 45 is wound once is shown in the figure, it is actually preferable to wind the tape 45 a plurality of times.

このような柔軟・有色のエッジカバー４１を透明な水受ボウル２１に取り付けることにより、水受ボウル２１の上端縁の存在が明確となる。このため、手洗いの際に利用者の手が上端縁にぶつからないように注意喚起することができる。また、万一、利用者が上端縁にぶつかった場合でも、エッジカバー４１が柔軟素材にて形成されているため、エッジのままの製品に比して、利用者の不快感も大幅に軽減される。さらに、板材に割れが生じた場合でも、割れ目がエッジカバー４１によって覆われ露出しないため、割れ部分に手が当たってしまうことがない。従って、当該水はね防止具１は、利用者の使用感が損なわれず、子供や高齢者でも安心して手洗いを行うことが可能となる。 By attaching such a flexible / colored edge cover 41 to the transparent water receiving bowl 21, the presence of the upper edge of the water receiving bowl 21 becomes clear. For this reason, it is possible to call attention so that the user's hand does not hit the upper edge when washing hands. In addition, even if the user hits the upper edge, the edge cover 41 is formed of a flexible material, so that the user's discomfort is greatly reduced compared to the product with the edge. The Furthermore, even when a crack occurs in the plate material, the crack is covered with the edge cover 41 and is not exposed, so that the hand does not hit the cracked portion. Therefore, the water splash preventing device 1 does not impair the user's feeling of use, and even a child or an elderly person can perform hand washing with peace of mind.

加えて、有色のエッジカバー４１は、透明な水受ボウル２１に対してデザイン上のアクセントともなる。従って、水はね防止具１の意匠的な美観も向上し、デザイン上の特徴を構成しつつ、利用者の使い勝手の向上を図ることが可能となる。 In addition, the colored edge cover 41 also serves as a design accent for the transparent water receiving bowl 21. Therefore, the design aesthetics of the water splash preventing device 1 can be improved, and the user-friendliness can be improved while configuring the design features.

一方、当該水はね防止具１は、次のようにしてボウル部４に取り付けられる。図１に示すように、水はね防止具１は、水受ボウル２１の水栓孔２２に水栓５の導水管８を挿入する形でボウル部４に取り付けられる。この場合、水はね防止具１は、導水管８に沿って装着され、水受ボウル２１がボウル部４の底面に接触し、ガイドボス２４が排水口６内に挿入されるまで押し込まれる。そして、水受ボウル２１をボウル部４上に取り付けた後、ストッパ２７の吸盤２８を、給水タンク本体１１の側面に吸着させる。これにより、水はね防止具１は、水栓５に取り付けられる形で、ボウル部４上に安定的に固定される。なお、万一、水受ボウル２１の取付状態が安定しない場合には、前述のように、貫通孔２５に紐２６を取り付け、それをトイレルームの壁面などに固定しても良い。 On the other hand, the water splash prevention tool 1 is attached to the bowl part 4 as follows. As shown in FIG. 1, the water splash preventing device 1 is attached to the bowl portion 4 by inserting the water conduit 8 of the water tap 5 into the water tap hole 22 of the water receiving bowl 21. In this case, the water splash preventing device 1 is mounted along the water guide pipe 8 and is pushed in until the water receiving bowl 21 contacts the bottom surface of the bowl portion 4 and the guide boss 24 is inserted into the drain port 6. And after attaching the water receiving bowl 21 on the bowl part 4, the suction cup 28 of the stopper 27 is made to adsorb | suck to the side surface of the water supply tank main body 11. FIG. Thereby, the water splash prevention tool 1 is stably fixed on the bowl part 4 in the form attached to the faucet 5. If the attachment state of the water receiving bowl 21 is not stable, the string 26 may be attached to the through hole 25 and fixed to the wall surface of the toilet room as described above.

水はね防止具１をこのようにしてボウル部４に取り付けると、水受ボウル２１の裏面に形成されたボス３３がボウル部４の水受面４ａに当接する。図５は、ボス３３と水受面４ａとの当接部の構成を示す説明図である。図５に示すように、ボス３３の頂部が水受面４ａに当接すると、水受ボウル２１とボウル部４との間に隙間４６が形成される。これにより、水はね防止具１と水受面４ａとの間には、ボウル部４の仕様によらず、一定の距離（ボス３３の高さＨ）を持った間隙が確実に形成される。この場合、水受ボウル２１は、前述のように、吸盤２８によってしっかりとボウル部４上に固定されるため、水受ボウル２１がばたつかず、隙間４６も安定的に形成される。従って、水はね防止具１とボウル部４が密接しにくくなり、両者間内の水が容易に流出し、ボウル部４や水はね防止具１も汚れにくくなる。 When the water splash preventing device 1 is attached to the bowl portion 4 in this manner, the boss 33 formed on the back surface of the water receiving bowl 21 comes into contact with the water receiving surface 4 a of the bowl portion 4. FIG. 5 is an explanatory view showing a configuration of a contact portion between the boss 33 and the water receiving surface 4a. As shown in FIG. 5, when the top portion of the boss 33 contacts the water receiving surface 4 a, a gap 46 is formed between the water receiving bowl 21 and the bowl portion 4. Thereby, a gap having a certain distance (height H of the boss 33) is reliably formed between the water splash preventing device 1 and the water receiving surface 4a regardless of the specification of the bowl portion 4. . In this case, since the water receiving bowl 21 is firmly fixed on the bowl portion 4 by the suction cup 28 as described above, the water receiving bowl 21 does not flutter and the gap 46 is stably formed. Therefore, the water splash prevention tool 1 and the bowl part 4 are difficult to come into close contact with each other, and the water between the two easily flows out, and the bowl part 4 and the water splash prevention tool 1 are not easily contaminated.

なお、図１の水はね防止具１では、ガイドボス２４が排水口６に遊嵌状態で取り付けられるため、ガイドボス２４と排水口６の間には隙間が残存している。この隙間は、水受ボウル２１とボウル部４との間に生じる隙間４６と連通しており、隙間４６を流れる水も排水口６から適宜流出する。従って、水はね防止具１を取り付けた状態でも、隙間４６からの排水が阻害されず、水受ボウル２１とボウル部４との間に水が溜まってしまうことはない。 In the water splash preventing tool 1 of FIG. 1, the guide boss 24 is attached to the drain port 6 in a loosely fitted state, so that a gap remains between the guide boss 24 and the drain port 6. This gap communicates with a gap 46 formed between the water receiving bowl 21 and the bowl portion 4, and water flowing through the gap 46 also flows out from the drain port 6 as appropriate. Accordingly, even when the water splash preventing device 1 is attached, drainage from the gap 46 is not hindered, and water does not accumulate between the water receiving bowl 21 and the bowl portion 4.

このようなボウル部４では、フラッシュレバー１２を操作すると、水栓５の吐水口９から水道水が流出する。前述のように、水はね防止具１を取り付けない場合、手洗いやボウル部４からの跳ね返りにより、水滴がボウル部４から四方八方に飛び散る。これに対し、水はね防止具１を図１のようにボウル部４に装着すると、四方八方に飛散する水滴は、ボウル部４の上方まで立ち上がった水受ボウル２１に受け止められる。水受ボウル２１に受け止められた水滴は、その後、重力によって水受ボウル２１の下方に案内され、排水孔２３を介して、排水口６から給水タンク本体１１内へと排出される。 In such a bowl part 4, when the flush lever 12 is operated, tap water flows out from the water outlet 9 of the faucet 5. As described above, when the water splash preventing device 1 is not attached, water droplets are scattered from the bowl portion 4 in all directions by hand washing or rebounding from the bowl portion 4. On the other hand, when the water splash preventing device 1 is attached to the bowl portion 4 as shown in FIG. 1, water droplets scattered in all directions are received by the water receiving bowl 21 rising up above the bowl portion 4. The water droplets received by the water receiving bowl 21 are then guided to the lower side of the water receiving bowl 21 by gravity and are discharged from the drain outlet 6 into the water supply tank body 11 through the drain holes 23.

従って、本発明による水はね防止具１をボウル部４に装着することにより、手洗いの際に飛び散る水滴をボウル部４外に飛散させることなく水受ボウル２１内に回収し、排水口６へと流すことができる。このため、ボウル部４の周囲に水滴がかかることがなく、便座やトイレルームの床・壁、使用者の衣服などが濡れてしまうのを防止できる。特に、便座の倒立状態に関わらず便座への水はねを防止できるので、便座の水濡れにより、次のトイレ使用者が感じる不快感を大幅に低減することが可能となる。 Therefore, by attaching the water splash preventing device 1 according to the present invention to the bowl portion 4, water droplets scattered during hand washing are collected in the water receiving bowl 21 without splashing outside the bowl portion 4, and to the drain port 6. Can be flowed. For this reason, water drops are not applied to the periphery of the bowl portion 4, and the toilet seat, the floor / wall of the toilet room, the clothes of the user, and the like can be prevented from getting wet. In particular, water splashing on the toilet seat can be prevented regardless of the inverted state of the toilet seat, so that the discomfort felt by the next toilet user can be greatly reduced by the wetness of the toilet seat.

また、ボウル部４の汚れも防止でき、重いタンク上蓋７を取り外すことなく、トイレ清掃時も、水はね防止具１のみを洗浄すれば良く、トイレ掃除の負担軽減も図られる。さらに、当該水はね防止具１は、特別な工事や別の設備等を必要とすることなく、トイレルーム内の既存の手洗い器にも容易に設置でき、低コストにてボウル部４やトイレルームを清潔に保つことが可能となる。 Further, the bowl portion 4 can be prevented from being soiled, and only the water splash prevention tool 1 needs to be washed during toilet cleaning without removing the heavy tank upper lid 7, thereby reducing the burden of toilet cleaning. Further, the water splash prevention device 1 can be easily installed in an existing hand-washer in the toilet room without requiring special construction or other facilities, and the bowl unit 4 and the toilet can be installed at low cost. The room can be kept clean.

次に、本発明の実施例２である水はね防止具５１について説明する。図６は、本発明の実施例２である水はね防止具におけるエッジカバー固定部の構成を示す説明図である。水はね防止具５１では、エッジカバー４１を水受ボウル２１の上縁部２１ｆに装着するに当たり、実施例１のテープ４５に代えて、図７のような固定片５２を使用している。固定片５２は、概ね、幅Ｗａ１０ｍｍ×長さＬ５０ｍｍ×厚さｔ０.２ｍｍ程度の合成樹脂シートであり、上縁部２１ｆに複数個形成された固定片取付孔５３に挿入される。なお、以下の実施例では、実施例１と同様の部材、部分については同一の符号を付し、その説明は省略する。 Next, the water splash prevention tool 51 which is Example 2 of this invention is demonstrated. FIG. 6 is an explanatory diagram illustrating a configuration of an edge cover fixing portion in the water splash preventing device according to the second embodiment of the present invention. In the water splash preventing device 51, when the edge cover 41 is attached to the upper edge portion 21f of the water receiving bowl 21, a fixing piece 52 as shown in FIG. 7 is used instead of the tape 45 of the first embodiment. The fixed piece 52 is generally a synthetic resin sheet having a width Wa 10 mm × length L 50 mm × thickness t0.2 mm, and is inserted into a plurality of fixed piece attachment holes 53 formed in the upper edge portion 21f. In the following embodiments, the same members and portions as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

固定片５２は、帯状のシート片５４と、シート片５４の一端側に形成されたきのこ形状のフック部５５と、シート片５４の他端側に形成された半円形の尾端部５６とを有している。フック部５５は、半円形の頭端部５７と、固定片５２のシート片５４から幅方向に張り出す形で設けられた係止部５８とから構成されている。一方、固定片５２の他端側も半円形の尾端部５６となっている。つまり、固定片５２は両端が曲線状に形成されており、組付作業時や防止具使用時に、作業者や利用者が固定片５２によって怪我を負わないよう安全性が考慮されている。固定片５２の尾端部５６側には、３本の折り目５９ａ〜５９ｃ（第１の折り目〜第３の折り目）が付けられている。固定片５２は、各折り目５９ａ〜５９ｃに沿って折り曲げることができるようになっている。 The fixed piece 52 includes a belt-like sheet piece 54, a mushroom-shaped hook portion 55 formed on one end side of the sheet piece 54, and a semicircular tail end portion 56 formed on the other end side of the sheet piece 54. Have. The hook portion 55 includes a semicircular head end portion 57 and a locking portion 58 provided so as to protrude from the sheet piece 54 of the fixed piece 52 in the width direction. On the other hand, the other end side of the fixed piece 52 is also a semicircular tail end portion 56. That is, both ends of the fixed piece 52 are formed in a curved shape, and safety is taken into consideration so that an operator and a user are not injured by the fixed piece 52 during the assembling work or the use of the prevention tool. Three folds 59a to 59c (first to third folds) are attached to the fixed piece 52 on the tail end portion 56 side. The fixed piece 52 can be bent along the folds 59a to 59c.

図８は、固定片５２によってエッジカバー４１を取り付ける手順を示す説明図である。ここではまず、図８（ａ）のように、固定片５２の尾端部５６を水受ボウル２１の内側から固定片取付孔５３に挿入する。次に、折り目５９ａを折り曲げた後、折り目５９ｃに沿って、尾端部５６を上縁部２１ｆを越える形で水受ボウル２１の内側に折り曲げる（図８（ｂ））。その状態で、折り目５９ａから先の尾端部５６を固定片取付孔５３に挿入する（図８（ｃ））。そして、尾端部５６が固定片取付孔５３から抜け出ないように押さえつつ、頭端部５７を引っ張り、折り目５９ｂを折り曲げる（図８（ｄ））。これにより、固定片取付孔５３に挿入された固定片５２のシート片５４が、折り目５９ａ〜５９ｃが折り曲げられた状態で、上縁部２１ｆに巻き付いて保持される。 FIG. 8 is an explanatory diagram showing a procedure for attaching the edge cover 41 with the fixing piece 52. Here, first, as shown in FIG. 8A, the tail end portion 56 of the fixed piece 52 is inserted into the fixed piece mounting hole 53 from the inside of the water receiving bowl 21. Next, after folding the fold 59a, the tail end portion 56 is folded inward of the water receiving bowl 21 along the fold 59c so as to exceed the upper edge portion 21f (FIG. 8B). In this state, the tail end portion 56 ahead of the fold 59a is inserted into the fixed piece mounting hole 53 (FIG. 8C). Then, while pressing the tail end portion 56 so as not to come out of the fixed piece mounting hole 53, the head end portion 57 is pulled to fold the fold 59b (FIG. 8D). Thereby, the sheet piece 54 of the fixed piece 52 inserted into the fixed piece attachment hole 53 is wound and held on the upper edge portion 21f in a state where the folds 59a to 59c are bent.

固定片５２を固定片取付孔５３に挿入し、上縁部２１ｆに巻き付かせた後、上縁部２１ｆにエッジカバー４１を取り付ける（図８（ｅ））。そして、エッジカバー４１を覆うように、頭端部５７を水受ボウル２１の内側から外側に巻き付け（図８（ｆ））、フック部５５を固定片取付孔５３に挿入し係合させる（図８（ｇ））。固定片取付孔５３は台形状となっており、フック部５５が入れやすく、抜けにくい形状となっている。この場合、固定片取付孔５３の上底部５３ａは、固定片５２のシート片５４よりも若干大きい寸法Ｗｕとなっている（Ｗｕ＞Ｗａ）。これに対し、下底部５３ｂの幅Ｗｄは、上底部５３ａより広いが、係止部５８の幅Ｗｋよりは小さくなっている（Ｗｄ＜Ｗｋ）。従って、フック部５５は、固定片取付孔５３に下底部５３ｂ側から斜めに挿入され、その後、孔から出た係止部５８が固定片取付孔５３の側縁５３ｃに引っ掛かり抜け止めされる。これにより、固定片５２は、エッジカバー４１の周りに巻き付いた状態で固定片取付孔５３に固定され、エッジカバー４１は、水受ボウル２１の上縁部２１ｆを挟持しつつ、水受ボウル２１の上端部に固定される。 After the fixed piece 52 is inserted into the fixed piece attachment hole 53 and wound around the upper edge portion 21f, the edge cover 41 is attached to the upper edge portion 21f (FIG. 8E). Then, the head end portion 57 is wound from the inside to the outside of the water receiving bowl 21 so as to cover the edge cover 41 (FIG. 8 (f)), and the hook portion 55 is inserted into the fixed piece mounting hole 53 and engaged (FIG. 8). 8 (g)). The fixed piece mounting hole 53 has a trapezoidal shape so that the hook portion 55 can be easily inserted and is not easily removed. In this case, the upper bottom 53a of the fixed piece mounting hole 53 has a dimension Wu that is slightly larger than the sheet piece 54 of the fixed piece 52 (Wu> Wa). In contrast, the width Wd of the lower bottom portion 53b is wider than the upper bottom portion 53a, but is smaller than the width Wk of the locking portion 58 (Wd <Wk). Accordingly, the hook portion 55 is inserted into the fixed piece mounting hole 53 obliquely from the lower bottom portion 53 b side, and thereafter, the locking portion 58 coming out of the hole is caught by the side edge 53 c of the fixed piece mounting hole 53 and is prevented from coming off. Thereby, the fixed piece 52 is fixed to the fixed piece attachment hole 53 in a state of being wrapped around the edge cover 41, and the edge cover 41 holds the upper edge portion 21 f of the water receiving bowl 21 while holding the water receiving bowl 21. It is fixed to the upper end of the.

さらに、本発明の実施例３である水はね防止具６１について説明する。図９は、本発明の実施例３である水はね防止具６１におけるエッジカバーの取付構造を示す説明図であり、（ａ）は水受ボウル２１の内側から、（ｂ）は水受ボウル２１の外側からエッジカバーの固定部を見た状態を示している。また、図１０はエッジカバー固定部の構成を示す断面図、図１１は実施例３の水はね防止具６１にて使用される固定フック６２の構成を示す説明図である。 Furthermore, the water splash preventing tool 61 which is Example 3 of this invention is demonstrated.

The state which looked at the fixing | fixed part of the edge cover from the outer side of 21 is shown. FIG. 10 is a cross-sectional view showing the configuration of the edge cover fixing portion, and FIG. 11 is an explanatory diagram showing the configuration of the fixing hook 62 used in the water splash preventing device 61 of the third embodiment.

図９〜１１に示すように、水はね防止具６１では、図１１の固定フック６２を使用してエッジカバー４１を固定している。固定フック６２は、断面が略Ｕ字状となった合成樹脂部材であり、エッジカバー４１の外側を覆う形で水はね防止具６１に装着される。固定フック６２の一端側には係合ボス６３が突設されており、係合ボス６３は、水受ボウル２１に形成されたフック取付孔６４に挿入嵌合される。係合ボス６３は、スリット６５によって上下に分割されている。また、係合ボス６３の中央にはピン挿入孔６６が形成されている。固定フック６２の係合ボス６３の裏面側には、円形の凹部６７が設けられている。 As shown in FIGS. 9 to 11, in the water splash preventing device 61, the edge cover 41 is fixed using the fixing hook 62 of FIG. 11. The fixing hook 62 is a synthetic resin member having a substantially U-shaped cross section, and is attached to the water splash preventing device 61 so as to cover the outer side of the edge cover 41. An engaging boss 63 projects from one end of the fixed hook 62, and the engaging boss 63 is inserted and fitted into a hook mounting hole 64 formed in the water receiving bowl 21. The engagement boss 63 is divided vertically by a slit 65. A pin insertion hole 66 is formed at the center of the engagement boss 63. A circular recess 67 is provided on the back side of the engagement boss 63 of the fixed hook 62.

水はね防止具６１では、まず、水受ボウル２１の上縁部２１ｆにエッジカバー４１を取り付ける。次に、フック取付孔６４の位置に合わせて、エッジカバー４１上に固定フック６２を装着する。そして、係合ボス６３をフック取付孔６４に挿入し、固定フック６２を水受ボウル２１に固定する。その際、係合ボス６３は、その先端部を窄める形でフック取付孔６４に挿入される。フック取付孔６４に挿入された係合ボス６３は、フック取付孔６４を抜けたところでスナップフィット状に先端部が開く。これにより、係合ボス６３は水受ボウル２１に抜け止めされる。その後、係合ボス６３が閉じて水受ボウル２１から抜け出てしまうのを防止するため、ピン挿入孔６６に脱落防止ピン６８を挿入する。 In the water splash preventing device 61, first, the edge cover 41 is attached to the upper edge portion 21 f of the water receiving bowl 21. Next, the fixing hook 62 is mounted on the edge cover 41 in accordance with the position of the hook mounting hole 64. Then, the engaging boss 63 is inserted into the hook mounting hole 64, and the fixing hook 62 is fixed to the water receiving bowl 21. At that time, the engaging boss 63 is inserted into the hook mounting hole 64 in such a manner that its tip is narrowed. The engaging boss 63 inserted into the hook mounting hole 64 opens at its tip end in a snap-fit manner when it passes through the hook mounting hole 64. As a result, the engagement boss 63 is prevented from coming off the water receiving bowl 21. Thereafter, in order to prevent the engagement boss 63 from closing and coming out of the water receiving bowl 21, the drop prevention pin 68 is inserted into the pin insertion hole 66.

脱落防止ピン６８は、一端側がキノコ状の頭端部６８ａ、他端側がフランジ部６８ｂとなっている。脱落防止ピン６８は、頭端部６８ａからピン挿入孔６６に圧入気味に挿入される。そして、頭端部６８ａが凹部６７内に抜け出たところで、頭端部６８ａがピン挿入孔６６の開口縁に引っ掛かり抜け止めされる。一方、フランジ部６８ｂはピン挿入孔６６よりも大径となっており、頭端部６８ａが凹部６７内に抜け出たところで、係合ボス６３の先端部に当接するようになっている。このように、水はね防止具６１では、固定フック６２をエッジカバー４１上に嵌め込んで、係合ボス６３をフック取付孔６４に挿入し、脱落防止ピン６８を装着するだけで容易にエッジカバー４１を水受ボウル２１の上縁部２１ｆに固定することができる。 The drop-off prevention pin 68 has a mushroom-shaped head end portion 68a on one end side and a flange portion 68b on the other end side. The fall-off prevention pin 68 is inserted into the pin insertion hole 66 from the head end portion 68a in a press-fit manner. When the head end portion 68 a comes out into the recess 67, the head end portion 68 a is caught by the opening edge of the pin insertion hole 66 and is prevented from coming off. On the other hand, the flange portion 68b has a diameter larger than that of the pin insertion hole 66, and comes into contact with the distal end portion of the engagement boss 63 when the head end portion 68a comes out into the recess 67. As described above, in the water splash preventing device 61, the fixing hook 62 is fitted onto the edge cover 41, the engaging boss 63 is inserted into the hook mounting hole 64, and the drop prevention pin 68 is simply attached to the edge. The cover 41 can be fixed to the upper edge portion 21f of the water receiving bowl 21.
