On the other hand, Figures 4 to 8a, 8b is a view for explaining the flush toilet in the present invention, the toilet to which the present invention is applied as shown in these figures, as described above, the toilet for temporarily storing the feces by the user It has a main body 20, and comprises a seat plate 21A and a cover 21B mounted on the toilet main body 20 so as to be rotatable, and water is collected at the upper edge of the toilet main body 20. A plurality of ejection holes 22a for ejecting to 22 are formed at regular intervals.

One side of the toilet body 20 includes a water supply unit for directly supplying water from the water pipe 23 to the water collecting port 22 side of the toilet body 20 to discharge the excrement from the water collecting port 22 by forced suction. At the same time, the suction unit is provided to operate to open or close the drain passage 24 through which the feces flow.

The water supply unit directly supplies water from the water pipe 23 to the water inlet 22 through the discharge pipe 25b while simultaneously providing the linking shaft 27 rotating in the casing 26 along the inlet pipe 25a. It is possible to blow out into the discharge hole (22a), the inlet pipe (25a) is equipped with a one-way valve 28 for supplying water to one side and a control valve 29 that can arbitrarily set the water supply amount.

In addition, the interlocking shaft 27 is driven at a predetermined speed by driving the second gear 33 in engagement with the first gear 31 rotated by the electrically operated motor 30 via the idle gear 32. The second inlet hole (34b) having a first inlet hole (34a) and the groove (34c) is formed in the interlocking shaft (27), leading to one communication hole (34d) to 1 , It is configured to be divided into secondary and provided to the catchment (22) side.

In addition, as shown in FIG. 7B, when the interlocking shaft 27 is continuously rotated by the driving of the motor 30, a slightly larger amount of primary than the first over the entire section of the groove 34c and the second inlet hole 34b is achieved. By supplying water secondarily, the water can be filled in the water collecting port 22 through the communication hole 34d and the discharge pipe 25b.

Thereafter, while the cam 30 continues to rotate, the piston 37 is pushed into the cylinder 36 to resist the elasticity of the spring 39, thereby blocking the drain passage 24, and at the same time, the second gear described above. Protruding bar 33a of (33) operates the touch switch 33b to stop the operation of the motor 30, so that a single use of the toilet seat is made.

Thus, the present invention can supply the minimum water directly through the water pipe 23 without the need for a separate tank, as well as by applying a predetermined suction force to the drain passage 24 in the water collecting port 22 to remove the excrement at once. Since it can be configured so that the noise and water consumption can be greatly suppressed, it is possible to block the drain passage 24 itself by the piston 37 to prevent the occurrence of odor.

The technical problem of the present invention is achieved by the technical configuration as described above, although the present invention has been described by a limited embodiment and drawings, the present invention is not limited thereto but by those skilled in the art to which the present invention pertains. Various modifications and variations are possible without departing from the spirit and technical scope of the claims to be described below.
