When the second bellows component 335 is passed through the outlet 224, a gap is formed between the outlet 224 and the second bellows component 335. Condensed water or the like accumulated on the upper surface of the lid 22 flows into the cleaning water tank 20 from the gap between the outlet 224 and the second bellows component 335.

  As shown in FIGS. 4 to 6, a plurality of rib portions 225 are formed on the peripheral edge of the outlet port 224 in the lid main body 221. The plurality of rib portions 225 are each formed in a plate shape. The plurality of rib portions 225 respectively extend in the penetrating direction of the outlet port 224 on the surface (first surface) 221 a and the back surface (second surface opposite to the first surface) 221 b of the lid main body 221.

  The rib portion 225 extends in the radial direction of the outlet port 224 and extends inward in the radial direction of the outlet port 224. The radial direction of the outlet port 224 is a direction orthogonal to the tangent of the outlet port 224. In the present embodiment, a plurality of rib portions 225 are provided, and the plurality of rib portions 225 are radially arranged side by side in the circumferential direction at the periphery of the outlet port 224.

  When viewed in the circumferential direction of the outlet port 224, each of the rib portions 225 is formed in a substantially semicircular shape extending across the surface 221a and the back surface 221b of the lid main body 221, as shown in FIG. As shown in FIG. 6, the plurality of rib portions 225 are, respectively, an upper side rib 225 a (rib portion) rising upward from the surface 221 a of the lid main body 221 in the vertical direction, and a vertical direction from the back surface 221 b of the lid main body 221. And a lower side rib 225b (rib portion) rising downward. The upper side rib 225a and the lower side rib 225b are continuously formed across the outlet 224 in the lid main body 221. The upper side rib 225 a and the lower side rib 225 b guide the hand-washing side water supply pipe 33 (second bellows component 335) to the inside in the radial direction of the outlet port 224.

  Each of the plurality of rib portions 225 (upper side rib 225a and lower side rib 225b) has a curved portion which is convex inward in the radial direction of the outlet port 224, as shown in FIG. Specifically, in the present embodiment, as shown in FIG. 6, at the inner end of the outlet 224, the corners of the upper end and the lower end of the plurality of ribs 225 are the outlet It has a rounded radius (R) formed to be convex inward in the radial direction of 224. In addition, the radius (R) of the corner in the rib portion 225 may be all rounded continuously from the upper end portion to the lower end portion of the rib portion 225, and the upper end portion and / or the lower end portion Only part may be rounded (R) and the other part may be straight.

Therefore, the second bellows constituting portion 335 of the hand-washing side water supply pipe 33 contacts the rib portion 225 even if the second bellows constituting portion 335 moves, so the plate-like portion of the periphery of the outlet 224 in the lid main body 221 Hard to touch the edge of

The distance L1 between the rib portions 225 adjacent in the circumferential direction is smaller than the diameter L2 of the second bellows forming portion 335 of the hand-washing side water supply pipe 33, as shown in FIG. Specifically, in the plurality of rib portions 225 arranged radially, the distance between the adjacent rib portions 225 is L1. The outer diameter of the second bellows component 335 of the hand-washing water supply pipe 33 is L2. And as shown in FIG. 5, the space | interval L1 of the rib part 225 which adjoins is set smaller than the diameter L2 of the 2nd bellows structure part 335 of the hand-washing side water supply piping 33. As shown in FIG.
Therefore, it is suppressed that the hand-washing side water supply piping 33 is obstruct | occluded by the adjacent rib part 225, and entraps between the adjacent rib parts 225. As shown in FIG. Thereby, the hand-washing side water supply piping 33 is hard to be caught by the peripheral part of the outlet 224.

  The 2nd bellows composition part 335 of hand-washing side water supply piping 33 is formed in the shape of a bellows. The bellows-like portion of the second bellows-constituting portion 335 of the hand-washing water supply pipe 33 is less likely to be caught on the peripheral portion of the outlet port 224, and the bellows-like portion is less likely to be damaged.

The length Lb of the rib portion 225 in the penetration direction of the outlet port 224 is, as shown in FIG. 7, an adjacent mountain shape of the second bellows component 335 in a state where the second bellows component 335 is elongated in the length direction. It is longer than the interval La of the convex portions 331a. The “state in which the second bellows forming portion 335 is extended in the length direction” is a state in which the second bellows forming portion 335 is pulled to extend in the length direction when the hand-washing water supply pipe 33 is constructed. Specifically, in the present embodiment, the second bellows forming portion 335 of the hand-washing side water supply pipe 33 has a bellows structure in which mountain folding and valley folding are alternately repeated. The distance between the adjacent mountain-shaped convex portions 331 a is the distance between the mountain-folded portion and the mountain-folded portion. For example, as shown in FIG. 7, the distance between adjacent mountain-like convex portions 331 a is La. The length in the penetration direction of the outlet port 224 in the rib portion 225 is Lb. Further, as shown in FIG. 7, the length Lb of the rib portion 225 in the penetration direction of the outlet port 224 is set to be longer than the interval La between the adjacent mountain-like convex portions 331a.
Therefore, the rib portion 225 is inhibited by the adjacent mountain-shaped convex portions 331 a and is prevented from entering between the adjacent mountain-shaped convex portions 331 a in the second bellows-formed portion 335 of the hand-washing water supply pipe 33. Therefore, the second bellows constituting portion 335 of the hand-washing side water supply pipe 33 is not easily caught by the outlet port 224.

Washing water is supplied to the washing water tank 20 described above via a water supply unit (not shown).
Further, a drain port which is opened and closed by a float valve (not shown) is formed in the lower portion of the tank body 21. Then, the float valve is pulled up and the drainage port is opened, so that the flush water stored inside the tank body 21 flows out from the drainage port (not shown) and is supplied to the toilet 10 to wash the toilet body 11. Ru.

According to the toilet bowl cleaning device 100 of the present embodiment described above, the following effects can be obtained.
The toilet bowl cleaning apparatus 100 of the present embodiment is disposed through the flush water tank 20 having the lid portion 22 provided with the outlet port 224, and the outlet port 224, and the hand-washing side water supply pipe for extracting water from the inside of the flush water tank 20. 33, and extends in the penetrating direction of the outlet port 224 on the front surface 221a and the back surface 221b of the lid main body 221 at the peripheral edge of the outlet port 224 in the lid main body 221, The rib portion 225 is formed to guide the inside of the outlet port 224 in the radial direction.

Therefore, when the hand-washing water supply pipe 33 is disposed through the lead-out port 224, the edge of the peripheral edge of the lead-out port 224 in the lid main body 221 is contacted rather than in contact , The upper side rib 225a or the lower side rib 225b. Thereby, the hand-washing side water supply pipe 33 is guided to the inside in the radial direction of the lead-out port 224, and contact with the edge of the peripheral edge of the lead-out port 224 in the lid main body 221 is reduced. The piping 33 can be reduced.
Further, since the hand-washing side water supply pipe 33 can be prevented from being caught around the periphery of the outlet port 224, the diameter of the outlet port 224 can be made smaller corresponding to the diameter of the hand-washing side water supply pipe 33. As a result, it is possible to reduce the splashing of droplets from the inside of the flush water tank 20 and to reduce the noise emitted from the inside of the flush water tank 20.

  The rib portion 225 has a curved portion which is convex inward in the radial direction of the outlet port 224. Therefore, even if the rib portion 225 contacts the hand-washing side water supply pipe 33, the hand-washing side water supply pipe 33 contacts the curved portion of the rib portion 225, so that breakage of the hand-washing side water supply pipe 33 can be reduced.

  The rib portion 225 extends in the radial direction of the outlet port 224. Therefore, the water collected on the upper surface of the lid main body 221 of the lid portion 22 is guided along the radial direction of the outlet port 224, so that the water can easily flow into the outlet port 224.

  The rib portion 225 extends radially inward of the outlet port 224. Therefore, the rib portion 225 protrudes inward in the radial direction of the outlet port 224 more than the plate-like edge of the peripheral edge of the outlet port 224 of the lid body. Thereby, the rib 225 is contacted without contacting the plate-like edge of the peripheral edge of the outlet port 224 of the lid body. Therefore, the hand-washing side water supply pipe 33 is hard to be caught by the outlet 224.

  The distance L1 between the adjacent rib portions 225 is smaller than the diameter L2 of the hand-washing water supply pipe 33. Therefore, it is suppressed that the hand-washing side water supply piping 33 is obstruct | occluded by the adjacent rib part 225, and entraps between the adjacent rib parts 225. As shown in FIG. Thereby, the hand-washing side water supply piping 33 is hard to be caught by the peripheral part of the outlet 224.

  The 2nd bellows composition part 335 of hand-washing side water supply piping 33 is formed in the shape of a bellows. The bellows-like portion of the second bellows-constituting portion 335 of the hand-washing water supply pipe 33 is less likely to be caught on the peripheral portion of the outlet port 224, and the bellows-like portion is less likely to be damaged.

  The length La of the lead-out port 224 in the rib portion 225 in the penetration direction is equal to the distance Lb of the adjacent convex convex portions 331 a in the second bellows constituting portion 335 in a state where the second bellows constituting portion 335 is elongated in the length direction. Too long. Therefore, the rib portion 225 is inhibited by the adjacent mountain-shaped convex portions 331 a and is prevented from entering between the adjacent mountain-shaped convex portions 331 a in the second bellows-formed portion 335 of the hand-washing water supply pipe 33. Therefore, the second bellows constituting portion 335 of the hand-washing side water supply pipe 33 is not easily caught by the outlet port 224.
