Further, the supply of the sterilizing liquid is not limited to being linked to the washing operation, and the sterilizing liquid may be supplied regardless of the presence or absence of the washing operation. In this case, it is possible to provide an appropriate operation portion or the like to the toilet device 1. As a supply form of the sterilizing liquid, other various modifications can also be made.

The sterilizing liquid supply device 20 of the present embodiment and the toilet device 1 including the sterilizing liquid supply device 20 can effectively disperse the sterilizing liquid on the inner surface of the barrel portion 10 to be sterilized by the above configuration. In other words, the water diffusing portion 28 is provided with a flat surface-shaped water-dispersing surface portion 29 that faces upward, and is disposed opposite to the discharge port 25 with a gap interposed therebetween, thereby providing a spout that opens toward the lower side. The sterilizing liquid discharged from the discharge pipe 24 of the outlet 25 can be impacted. Further, the support portion 27 is provided to support the water diffusing portion 28 from the outside of the discharge tube 24. Therefore, the sterilizing liquid discharged from the discharge port 25 is caused to impinge on the water-spraying surface portion 29, and is scattered in the direction of the water-spreading surface of the water-spraying surface portion 29, and can be dispersed to a range covering substantially the entire circumference. Further, since the water-spraying portion 28 or the support portion 27 is less likely to cause a pressure loss than the other member inserted into the discharge tube, it is possible to suppress a decrease in the flow velocity and to cover a wide range of the inner surface of the barrel portion 10 to be sterilized. Effectively spread. In addition, since the sterilizing liquid that has hit the water-dispersing surface portion 29 is scattered in a droplet shape, even if ozone water or the like is used, for example, when the spray-like sterilizing liquid is sprayed, the sterilizing liquid tends to have a reduced concentration during spraying. It can suppress the decrease in its concentration.

In the present embodiment, the sterilizing liquid supply device 20 is configured to supply the sterilizing liquid to the inner surface of the barrel portion 10 to be sterilized around the peripheral wall portion. Therefore, the sterilizing liquid that has hit the water-dispersing surface portion 29 and is scattered in the direction of the water-dispersing surface can be attached to substantially the entire circumference of the inner circumferential surface portion of the barrel portion 10. Further, in the present embodiment, the discharge pipe 24 and the water-spraying portion 28 are disposed so as to be located in the peripheral wall portion of the tub portion 10 in plan view. Therefore, the sterilizing liquid supply line 23 can be made less conspicuous and easier to be piped than the discharge tube 24 and the water-spraying portion 28 are disposed at the center of the barrel portion 10, for example, in a plan view.

Furthermore, in the present embodiment, either or both of the plane orthogonal to the discharge direction of the discharge port 25 of the discharge pipe 24 and the water-dispersing surface portion 29 of the water-spraying portion 28 are provided so as to be inclined and oriented. The side of the perimeter wall opposite the premises. Therefore, with respect to the water-dispersing surface portion 29, the direction in which the discharge port 25 is discharged is in the illegal line direction, and the sterilizing liquid discharged to the water-dissipating surface portion 29 is scattered to the side opposite to the portion disposed in the barrel portion 10. . Thereby, the sterilizing liquid can be effectively dispersed on the side away from the arrangement place of the discharge pipe 24 and the water-spraying portion 28, that is, on the side of the peripheral wall portion facing the opposite side. Further, instead of such an aspect, it is also possible to set both of the surface orthogonal to the discharge direction of the discharge port 25 of the discharge pipe 24 and the water-dissipating surface portion 29 of the water-spraying portion 28 to be horizontal.

Furthermore, in the present embodiment, the discharge port 25 of the discharge pipe 24 is provided so that the sterilizing liquid impacts the portion on the side of the peripheral wall portion where the arrangement of the water-dispersing surface portion 29 of the water-spraying portion 28 is opposed. Therefore, the sterilizing liquid discharged from the water-dispersing surface portion 29 is scattered in the direction of the water-dispersing surface (radial direction) from the peripheral edge portion of the water-dispersing surface portion 29 along the direction of the surface of the water-dispersing surface portion 29, and the sterilizing liquid and the water-dissipating surface portion 29 The contact range is smaller in the circumferential direction than the portion on the side opposite to the arrangement of the location. Thereby, it is possible to effectively suppress a decrease in the flow rate of the sterilizing liquid scattered through the portion, and to effectively move away from the side where the discharge pipe 24 and the water-spraying portion 28 are disposed, that is, the side of the peripheral wall portion that is opposed to each other. Disperse the sterilizing solution. Further, instead of such a state, the discharge port 25 of the discharge pipe 24 may be changed so that the sterilizing liquid will hit the approximately central portion of the water-dissipating surface portion 29.

Further, in the present embodiment, the support portion 27 supports the structure of the water diffusing portion 28 from the lower side. Therefore, compared with the case where, for example, the support portion 27 is coupled to the peripheral portion of the water-dispersing surface portion 29, it is possible to suppress the sterilizing liquid that has hit the water-spraying surface portion 29 from escaping in the form of sliding along the support portion 27, and it is possible to more effectively disperse water. The surface of the face 29 is scattered in the direction of the water surface. Further, instead of such an aspect, the support portion 27 may be modified to support the structure of the water diffusing portion 28 from the side. In this case, the support portion 27 may be connected to the outer peripheral portion of the lower end side of the water diffusing portion 28.

Furthermore, in the present embodiment, the support portion 27 is supported by the discharge tube 24. Therefore, compared with the case where the support portion 27 is supported by, for example, the body portion 10 to be sterilized or another portion of the toilet body, the discharge port 25 of the discharge pipe 24 and the water-dissipating surface portion 29 are less likely to be placed at the time of installation. Errors, etc., can effectively spread the liquid. Further, instead of this aspect, the support portion 27 may be supported by the body portion 10 or other portions of the toilet body.

Further, in the present embodiment, the water-spreading surface portion 29 of the water-spraying portion 28 is provided to be slightly rounded as viewed in a direction perpendicular to the water-spreading surface. Therefore, compared with the case where the water-spreading surface portion 29 is provided in a polygonal shape, the sterilizing liquid scattered by the peripheral edge portion of the water-dispersing surface portion 29 is likely to be substantially annular or substantially U-shaped on the inner surface of the barrel portion 10 to be sterilized. The surface of the sterilizing object is slightly rounded or slightly rounded in a plan view when it is attached in a word shape. Further, the shape viewed from the direction perpendicular to the water-spreading surface of the water-spraying surface portion 29 of the water-spraying portion 28 can be changed to a slightly rounded shape or a slightly polygonal shape instead of a slightly rounded shape. In this case, the water diffusing portion 28 may be provided in a slightly cylindrical shape or a slightly polygonal column shape in accordance with the shape of the water dissipating surface portion 29. Further, in the present embodiment, the water-spraying portion 28 is shown as a columnar shape, but it may be a thin plate or the like.

In the present embodiment, the discharge pipe 24 and the water-spraying portion 28 are disposed so as to be located inside the inner peripheral wall of the inner side of the depth of the toilet in the peripheral edge portion of the peripheral wall portion of the body portion 10 of the body to be sterilized. It is set in the depth direction of the toilet, the front side, or the side of the toilet width direction. In addition, the aspect in which the discharge tube 24 and the water-spraying portion 28 are disposed so as to be located in the peripheral wall portion of the sterilization target in a plan view is not limited to the peripheral portion of the opening of the barrel portion 10, and may be provided, for example, in the opening portion. The toilet lid 5 or the inner surface of the toilet seat 4 and the like. Further, in this manner, the discharge tube 24 and the water-spraying portion 28 may be disposed so as to be positioned in the peripheral wall portion of the sterilization target in a plan view, and may be disposed in the center of the sterilization target in plan view. Department and so on. For example, the discharge tube 24 and the water-spraying portion 28 may be disposed on the inner surface of the toilet lid 5 so as to be positioned in the center portion of the tub portion 10 in plan view. Various other modifications can be made to the arrangement of the discharge pipe 24 and the water diffusing portion 28.

In the present embodiment, the trap portion 16 of the toilet device 1 is shown as a rotary trap, but the invention is not limited thereto. For example, a siphon jet or a siphon, a siphon vortex, a neo-vortex, a wash down, or the like may be employed. In this case, as described above, when the water level is lowered, an appropriate water level variable mechanism can be provided to maintain the water level of the barrel portion 10 at a low water level LV2 lower than the water level LV1. Further, in the present embodiment, the toilet device 1 is set as a seat type toilet device, but may be a squat toilet device or a urinal.

Further, in the present embodiment, the sterilizing liquid supply device 20 is integrally incorporated into the toilet device 1 as an example, but it may be attached to the toilet device 1. In this case, if it is necessary to supply water to the sterilizing liquid supply device 20, the water supply line provided in the toilet device 1 can be appropriately branched to be connected to the water supply line 21 of the sterilizing liquid supply device 20. In the present embodiment, the sterilization target of the sterilizing liquid supply device 20 is exemplified as the tub body portion 10 of the toilet device 1, but the invention is not limited thereto. For example, the sterilizing liquid supply device 20 may be disposed on a sterilizing object surrounded by the peripheral wall portion, such as a sink provided in the tub or the sink of the washbasin, a sink in the kitchen, or a tub, laundry.
