A pressure means and a pressurizing means for bringing into a pressurized state are connected to each other, and further, a discharge pipe is connected to a lower portion of the temporary storage tank through a valve mechanism, and this is connected to a storage tank. Things exist.

In this publicly known toilet device, when the cleaning switch is operated after the toilet is used, the cleaning water flows down the inner surface of the toilet via the cleaning pipe, and the negative pressure means is activated to create a negative pressure in the temporary storage tank. When the negative pressure state reaches a certain value, the valve mechanism on the toilet side opens, and the dirt flows into the temporary holding tank together with the wash water.

Next, when the filth flows into the temporary storage tank, the valve mechanism on the toilet side is closed, and in this state, the pressurizing means is actuated to bring the interior of the temporary storage tank into a pressurized state. When the value reaches a certain value, the valve mechanism on the storage tank side opens and the waste in the temporary storage tank flows into the storage tank through the discharge pipe, and then the valve mechanism on the storage tank side closes. There is.

[0005]

The conventional toilet device described above has the following inconveniences.

That is, since the temporary holding tank has a relatively small capacity, when the temporary holding tank is in a negative pressure state, the negative pressure means often sucks the waste in the temporary holding tank. That there is

[0007] Further, the filth sucked into the temporary storage tank is discharged to the discharge pipe in a pressurized state in the temporary storage tank, but after that, it is guided to the storage tank by natural fall, so that the discharge pipe is long. In such a case, or when there is a bent portion, there is a problem such that the flow of filth deteriorates.

The filth that has flowed into the guide pipe 11 is
The two spirally curved annular portions 11a and 11b flow down while swirling. Particularly, since the annular portions 11a and 11b are curved in the vertical direction, a strong swirling flow occurs, and this swirling flow and Due to the flow inertia that is combined with the pressurizing action, the waste material flows down vigorously and is discharged to the storage tank 10.

Intake valve 9, discharge valve 14 and gate valve 18
The opening / closing operation, the supply of pressurized air to the ventilation part 17 and the wash water tank 22, and the operation of the negative pressure means 19 are automatically controlled by an electric control circuit including a solenoid valve.

[0035]

As described above, according to the present invention, the toilet bowl and the storage tank are connected by the discharge pipe equipped with the suction valve and the guide pipe, and discharged to the connection position between the guide pipe and the storage tank. Since a valve is provided and the inside of the pipe between the suction valve and the discharge valve is put in a negative pressure state and then in a pressurized state, the action of inhaling sewage after use and the action of releasing sewage after inhalation are achieved. This can be achieved quickly and reliably, and the negative pressure inside the pipe is performed with the suction valve closed and the dirt is sucked with the sluice valve closed, so that the negative pressure means sucks the dirt. Moreover, the presence of the guide pipe has the advantage that the flow inertia can be used for discharging the waste.

In particular, according to the second aspect of the invention, it is possible to obtain a large flow inertia, and it is possible to smoothly transfer the waste from the discharge pipe to the guide pipe by the connecting pipe.

According to the third aspect of the present invention, the flow of the filth by the compressed air is effectively performed from the upstream side to the downstream side.
