The additive charging cylinder 142 stores and stores therein the additive charged from the additive charging port 140a. The additive contained in the additive charging cylinder 142 is charged into the first duct 210 from the additive charging cylinder 142.

The additive charging cylinder 142 inputs the additive contained in the additive charging cylinder 142 into the first duct 210 in conjunction with the operation of the rotation operation of the screw member 310 by the operation lever 131 (described later). Then, the additive introduced into the first duct 210 is conveyed below the first opening 111c of the toilet body 111 by the screw member 310, whereby a predetermined amount of additive is supplied to the stool. Therefore, the additive thrown into the first duct 210 is conveyed below the first opening 111c of the toilet body 111 by the screw member 310, so that the downstream side of the first opening 111c of the toilet bowl 111a, An additive can be added (supplied) to the stool dropped from the first opening 111c of the toilet bowl 111a. In the present embodiment, the downstream side of the first opening 111c of the toilet bowl 111a is a position below the first opening 111c of the toilet bowl 111a.

After the additive is conveyed toward the lower side of the first opening 111c of the toilet body 111 by the conveying unit 300, the additive contained in the additive charging cylinder 142 is transferred to the conveying unit 300 (screw member 310). ) Is moved by its own weight into the gap between the transfer unit 300 (screw member 310) and the inside of the first duct 210 generated by the transfer. The additive that has moved into the first duct 210 is transported below the first opening 111c of the toilet body 111 by the transport unit 300 (screw member 310). In conjunction with the rotation operation of the transport unit 300, the addition of the additive from the additive charging cylinder 142 to the first duct 210 is repeated.

The additive supply unit 140 configured as described above allows the additive stored and stored in the additive charging cylinder 142 to be added in conjunction with the rotation operation of the transport unit 300 (screw member 310). It is put into the first duct 210 by its own weight. The additive introduced into the first duct 210 is moved below the first opening 111c of the toilet bowl 111a by the transport unit 300 (screw member 310) and transported by the transport unit 300 (screw member 310).

The entraining conveyance unit 420 includes a plate-like member 421, a first conveyance plate 422, and a second conveyance plate 423. Therefore, in the entraining conveyance unit 420, stool is entrained by the plate-like member 421, and the stool is conveyed downstream by the first conveyance plate 422 and the second conveyance plate 423. Since the 1st conveyance board 422 and the 2nd conveyance board 423 in the entraining conveyance part 420 incline with respect to the conveyance direction, the stool dropped from the 1st opening part 111c of the toilet bowl 111a is conveyed downstream. The conveyance force can be improved.

Further, when the user operates the operation lever 131 to convey the stool dropped from the first opening 111c of the toilet bowl 111a to the downstream side, at the same time as the amount of additive on the upstream side of the toilet body 111 The cylindrical member 411 in the restricting portion 410 and the screw member 310 partially missing are rotated. Then, the additive contained in the additive charging cylinder 142 of the additive supply unit 140 is fed into the first duct 210 in a state where the supply amount is limited. The additive moves downward due to its own weight in the first duct 210 in the additive charging cylinder 142 and is sent in conjunction with the operation of the operation lever 131. In this way, a predetermined amount of additive can be supplied to the stool in conjunction with an operation of driving the transport unit 300 (stool transport mechanism unit 120) by the operation lever 131.

In this way, the additive amount restriction unit 410 reduces the amount of the additive that enters the volume of the cylindrical member 411, thereby reducing the amount of additive (the amount of supply) supplied by the additive supply unit 140. ) Can be adjusted.
