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.

  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).

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.
