By appropriately setting the height position of the inflow hole and outflow hole and the size of the outflow hole, for example, wastewater containing protein (pepton) such as soapy water and sebum flowing on the floor surface of the bathroom washroom is And can be prevented from entering from the outflow hole.

  Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited thereby.

  FIGS. 1-4 show the 1st reference example comprised so that generation | occurrence | production of slime in a drain outlet may be prevented with the chemical | medical agent which is installed in the drain outlet of the washroom of a bathroom, and inhibits formation of a biofilm. 1-4, 1 is a slime prevention tool for bathrooms, and is installed at the drainage port 3 of the bathroom washing place 2 to prevent the occurrence of slime at the drainage port 3 by the agent 4 that inhibits biofilm formation. It is configured. The slime generation prevention tool 1 includes a drug (for example, the dimer 38, hereinafter simply referred to as a drug) 4 that inhibits the formation of a biofilm and a container 5 that accommodates the drug. The container 5 includes a tray 6 on which a medicine 4 is placed, which has an upper opening 6a that is circular in plan view, and a dome-shaped lid 7 that is circular in plan view and covers the upper opening 6a. Both 6 and 7 are detachably mounted by a pair of upper and lower annular engaging claws A and B. The engaging claw A protrudes inward, and the lower end portion of the lid 7 is formed by the engaging claw A. Further, the engaging claw B protrudes above the tip of the outward flange F, and the flange F forms an upper opening 6a. The lid 7 has an inflow hole 8 for clean water (for example, water not containing protein (peptone) from a clean water supply source such as a shower) flowing into the container 5, while the tray 6 5 has an outflow hole 9 for the drug solution flowing out from the inside at a position lower than the inflow hole 8. The inflow hole 8 is provided in the center of the lid 7 and has a cross shape in a plan view so that foreign matter does not easily enter the container 5. In addition, a plurality of the outflow holes 9 are formed along the circumferential direction while maintaining the same height with an appropriate interval in the vertical outer peripheral portion M of the tray 6.

  The tray 6 includes a circular outer peripheral wall M in plan view, a vertical inner peripheral wall N in a circular shape in plan view, an annular drug solution storage chamber 10 having a width L surrounded by both M and N, and an inner peripheral wall N. The medicine mounting chamber 12 is formed by the inner peripheral wall N and the bottom 11. The medicine 4 has a disk shape, and in this embodiment, the medicine 4 is higher than the inner peripheral wall N. The medicine 4 is placed in the placement chamber 12 while being lifted from the top surface of the bottom 11 by a plurality of spacers 13 provided on the top surface of the bottom 11. Further, the drug solution storage chamber 10 is formed on the inner side of the flat part 14 with an annular flat part 14 on the inner side connected to the outer peripheral wall M and at an interval of 90 ° in circumferential angle. It comprises a plurality of legs 15. Then, a predetermined length is provided vertically downward from the bottom 11 to reach the lower surface portion 15 a of the leg 15.

A plurality of holes 16 are provided at appropriate intervals in the circumferential direction. Reference numeral 17 denotes a water draining hole provided at the lowest position of the inner peripheral wall N, and a plurality of holes 17 are provided at appropriate intervals in the circumferential direction. The drain hole 17 is provided below the outflow hole 9. The sizes of the hole 16 and the drainage hole 17 provided at the boundary between the flat portion 14 and the outer peripheral wall M are set to be smaller than the size of the outflow hole 9, respectively, and more than the drainage hole 17. The hole 16 is located at a lower position.

  Thus, the drainage port 3 of the bathroom washroom 2 is attached to and detached from the net-like hair catcher 19 fitted into the drainage round hole 18 of the drainage port 2 and the upper step portion S of the drainage port 3, for example, in order from the bottom. When the lid C with a drainage hole having a rectangular shape in a plan view and having a larger area than the drainage round hole 18 is provided, the slime prevention device 1 is placed on the lid C with the drainage hole via the legs 15. Placed. In this embodiment, it is assumed that the floor surface 2a of the washing place 2 and the upper surface of the cover C with drain holes are flush with each other.

  When using the bathroom, wastewater containing soapy water and protein (peptone) such as sebum flows through the cover C with the drainage hole while flowing on the floor surface 2a of the washing place 2, and from a clean water supply source such as a shower. Clean water flows into the inflow hole 8 of the slime prevention device 1 to dissolve a part of the drug 4 and the drug solution overflowed from the drug placement chamber 12 gradually accumulates in the drug solution storage chamber 10. To go. After a while, the overflowing drug solution in the drug solution storage chamber 10 reaches the height position of the outflow hole 9, and the drug solution in the drug solution storage chamber 10 flows out from the outflow hole 9, and has a drain hole lid. C, flows through the drainage port 3 including the hair catcher 19. Therefore, the occurrence of slime adhering to the drain port 3 can be prevented.

  Once the clean water supply source such as a shower is stopped, that is, when clean water does not flow into the container 5, the clean water that has flowed into the container 5 and accumulated in the container 5 first Since a part of the drug is dissolved and the drug solution is accumulated in the drug solution storage chamber 10, the drug solution is likely to become a saturated solution, and the dissolution of the drug is stabilized. When clean water is supplied again in this state, the drug solution flows out from the outflow hole 9 in such a manner that the saturated solution is diluted and mixed with the saturated solution. Therefore, the occurrence of slime adhering to the drain port 3 can be effectively prevented.

  By the way, as described above, it has been found that the drug 4 has a property of preventing the occurrence of slime when it comes into contact with wastewater containing proteins (peptone) such as soapy water and sebum. Therefore, in this reference example, the size of the hole 16 provided at the boundary between the flat portion 14 and the outer peripheral wall M is set to be smaller than the size of the outflow hole 9, and the height of the leg 15 is set appropriately. By increasing the height position of the hole 16 from the floor surface 2a, wastewater containing protein (pepton) such as soapy water and sebum flowing on the floor surface 2a can be discharged from the hole 16 and the hole 16 as much as possible. Is prevented from entering through the outflow hole 9 at a higher position.

  Further, by providing the drain hole 17 in the inner peripheral wall N, the drug solution does not continue to contact the drug 4 in the drug loading chamber 12 in a state where the drainage does not flow into the container 5. As described above, the drug solution can be prevented from staying in the drug loading chamber 12 for a long time.
