A water supply hose 94 is connected to the water supply mechanism 43 . The water supply mechanism 43 is arranged below from the rear of the nozzle part 41.

Air gap mechanism 5 is connected to water supply hose 94. The air gap mechanism 5 is provided upstream of the cleaning mechanism 4, and not only supplies a portion of the supplied cleaning water to the cleaning mechanism 4, but also prevents the cleaning water from flowing backward from the cleaning mechanism 4 on the downstream side. This is a mechanism for draining excess waste water of the washing water that has flowed into the air gap mechanism 5. The air gap mechanism 5 includes a main body portion 51 and an air gap lid portion 52.

As shown in FIG. 3, the main body portion 51 is constituted by a container capable of storing washing water flowing in from the upstream side. The main body portion 51 has an opening 511 , a bottom 512 , an outlet 513 , and a drain 514 . The opening 511 is formed by opening the upper part of the main body 51. The bottom 512 is a surface facing the opening 511. A step 512a is formed on the bottom portion 512. A surface extending toward the lower end of the main body portion 51 is a lower end surface 512b. An overflow surface 512c for preventing backflow is formed at a position shifted upward from the lower end surface 512b via a step 512a, that is, at a position higher than the lower end surface 512b and lower than the opening 511.

The outlet 513 is an opening connected to a water supply hose 94 that supplies cleaning water to the cleaning mechanism 4, and is provided at the bottom 512 of the main body 51. The outlet 513 is formed on the lower end surface 512b of the bottom portion 512. As shown in FIG. 3, the outlet 513 extends downward in a cylindrical shape from the lower end surface 512b. From the outlet 513, a water supply hose 94 passes under the functional section 3 and is connected to a pump (not shown).

The drain port 514 is an opening through which waste water flows, and is formed so as to be continuous with the overflow surface 512c of the bottom portion 512. The drain port 514 is an opening through which the cleaning water supplied from the upstream side is drained when it exceeds the amount of water that flows out from the outflow port 513. The drain port 514 is formed continuously from the overflow surface 512c located above the lower end surface 512b, so that when cleaning water accumulates in the main body part 51 and the water level rises, or when it flows back from the outflow port 513. In this case, the cleaning water is drained from the drain port 514 without reaching the upper end of the main body 51, thereby preventing the washing water from overflowing from the main body 51.

The air gap lid section 52 includes a first air gap lid section 521 and a second air gap lid section 522. The first air gap lid part 521 is a member that covers the opening 511 formed in the upper part of the main body part 51, and includes a first lid flat part 523 and a cleaning water supply part 524. The first lid flat portion 523 is constituted by a planar member having a contour that matches the contour of the portion of the main body portion 51 that meets the first air gap lid portion 521 .

As shown in FIG. 4, the cleaning water supply section 524 is a generally elliptical region that extends outward from the first lid flat section 523 with one end at the center of the first lid flat section 523. It is surrounded by a low side wall 524a that stands up from the flat surface part 523 of the first lid part. The side wall 524a is double formed with an outer side and an inner side, and the cleaning water supply section 524 has a flat section 525, an inlet 526, a water outlet 527, and a rectifying section 528.

The plane portion 525 is a surface of an area surrounded by the side wall 524a. A drainage slope is formed in the flat part 525 so that the second side 525b, which is closer to the center of the first lid flat part 523, is lower than the first side 525a, which is closer to the outside of the first lid flat part 523. has been done. The first side 525a is the upstream side and the second side 525b is the downstream side. The plane portion 525 is wide on the second side 525b and narrow on the first side 525a.

The inflow port 526 is provided in the first air gap lid part 521, and more specifically, is formed in the first side 525a of the wash water supply part 524. The inflow port 526 is formed in a cylindrical inflow tube portion 5260 extending downward from the first side 525a of the plane portion 525. A water supply hose 94 extending from the water supply valve 93 is attached to the inflow cylinder portion 5260, and the inflow port 526 allows cleaning water to flow toward a water spout 527 in the main body portion 51, which will be described later.

The water spout 527 is provided above the main body portion 51 and formed on the second side 525b of the first lid flat portion 523. The water spout 527 is arranged at a position away from the inlet 526 in the downstream direction. The water spout 527 has a water spout cylindrical portion 5270 (see FIG. 5) formed in a cylindrical shape that extends downward from the second side 525b in the water spouting direction to the main body portion 51. The water spouting tube portion 5270 extends in the vertical direction of the air gap mechanism 5, and the lower end of the water spouting tube portion 5270 is located within the main body portion 51. As shown by the bold line arrow in FIG. 3, the cleaning water supplied from the inlet 526 flows along the drainage slope of the flat portion 525. The water spout 527 discharges the washing water that has flowed in, as shown by the broken line arrow, toward the inside of the main body 51 through the water spout cylinder 5270 .

As shown in FIG. 5, the inner peripheral surface of the upper part of the water spout 527 that continues from the first lid flat part 523 to the water spout cylinder part 5270 is an R-shaped curved surface 527r. The water outlet 527 has a larger diameter than the inlet 526. The opening area of the water spout 527 is larger than the opening area of the inlet 526. The opening area of the water spout 527 refers to a substantially circular area excluding the rib portion 5281 of the rectifying portion 528, which will be described below. Thereby, the flow rate of the cleaning water flowing through the water spout 527 can be reduced, and splashing during water spouting can be suppressed.

The rectifying portion 528 is a portion that rectifies the flow of cleaning water that flows from the upstream side toward the water spout 527 and flows down to the main body portion 51 . In the cleaning water supply section 524, there is a certain width between the inlet 526 and the spout 527, so after passing through this and flowing into the spout 527, the flow may be turbulent depending on the amount and flow rate of the cleaning water supplied. There are cases. The rectifier 528 directs the flow of cleaning water from the spout 527 toward the inside of the main body 51 in a direction that intersects the vertical flow flowing from the spout 527 to the main body 51, that is, the vertical direction is the vertical direction. Then, the flow is rectified to suppress lateral turbulence. The flow straightening section 528 is provided at the water spout 527 and includes a rib section 5281 and an expansion section 5282.

The rib portion 5281 is formed at the water spout 527. As shown in FIGS. 3 to 5, the rib portion 5281 is a thin plate-shaped portion extending from the outer circumferential side of the water spout tube portion 5270 toward the center side of the water spout 527. The rib portion 5281 is formed along the flow direction of the cleaning water flowing down from the water spout 527 to the main body portion 51 . As shown in FIG. 5, in a cross-sectional view of the air gap mechanism 5, the rib portion 5281 has a distance D between a part of the inner wall of the water spouting tube portion 5270 and the side surface of the rib portion 5281 facing this inner wall. It is formed so that it gets closer as you go towards it. The rib portion 5281 is inclined so that the space into which water is discharged becomes smaller toward the downstream side. Therefore, the cross section of the rib portion 5281 itself becomes thicker from the upstream side toward the downstream side. The rib portion 5281 has a protruding portion 5283 that protrudes upstream from the water spout 527 and extends upward beyond the outer peripheral edge of the water spout 527 .

The expansion portion 5282 is formed on the free end side of the rib portion 5281. The expanding portion 5282 is a substantially circular curved surface that expands and has an outer diameter larger than the thickness of the plate surface extending from the base end side to the free end side of the rib portion 5281. The expansion portion 5282 is formed from the upper end to the lower end of the rib portion 5281. The expansion part 5282 is not a perfect circle, and a part of the outer periphery is connected to the rib part 5281, so the outer periphery of the circle is interrupted at the part connected to the rib part 5281. The term "substantially circular" is a concept that includes any imaginable circle including interrupted parts.

The second air gap lid part 522 is a flat lid that covers the flat part 525 of the first air gap lid part 521, as shown in FIG. An edge 522a that fits between the double side walls 524a that partitions the wash water supply section 524 protrudes downward from the lower surface of the second air gap lid 522. The second air gap lid part 522 is attached to the first air gap lid part 521 by fitting between the side walls 524a. Since the side wall 524a has a height, the second air gap lid 522 can be attached to the first air gap lid 521 even if the rectifier 528 protruding upward from the water spout 527 is disposed inside.

As shown in FIG. 5, when the second air gap lid part 522 covers the washing water supply part 524, the flat part 525 of the first air gap lid part 521 and the lower surface of the second air gap lid part 522 A space S is formed between them, and cleaning water is supplied into this space S.

The drain section 6 includes a drain tray 61 and a tray lid section 62. The drainage section 6 is arranged below the drying device 92.

The drainage tray 61 is a long, shallow, open-topped container that is disposed in the functional section 3 and extends from the air gap mechanism 5 to the front end of the functional section 3 . The drain tray 61 extends along the front-rear direction of the toilet main body 10 and has a vertically long bottom surface 611 and a side wall 612 that stands up around the bottom surface 611. The rear end side of the drain tray 61 is located below the drain port 514 of the air gap mechanism 5. The front end side of the drainage tray 61 is disposed at the front end of the functional section 3 without having a side wall 612. A drainage slope is formed in the drainage tray 61. The drainage gradient is a gradient in which the rear end side is upstream and the front end side is downstream. The drain tray 61 drains waste water drained from the air gap mechanism 5. As shown in FIG. 3, the drainage tray 61 is formed with a step 613 such that the downstream side is located lower than the upstream side.

The tray cover 62 is a flat member that covers the upper opening of the drain tray 61. As shown in FIG. 3, the tray lid portion 62 covers the area from the bottom of the drain port 514 of the air gap mechanism 5 in the drain tray 61 to beyond the step 613 to the front of the step 613. The tray lid portion 62 has a step 623 formed on the front end side, and covers the front end side including the step 613 of the drain tray 61. Thereby, the height of the upper part of the drainage part 6 is formed so that the downstream side is located lower than the upstream side.

The tray lid portion 62 has locking surfaces 621 that hang down from both sides in the width direction. A locking hole 622 penetrating the locking surface 621 is formed in the center. The tray cover 62 is locked to the drain tray 61 by locking the locking hole 622 to the locking protrusion 614 protruding from the outside of the side wall 612 of the drain tray 61 .
