When pressurized air is supplied from the inlet / outlet port 34 into the cylinder 30 from this sealed state, the piston 32 laterally moves to the right in the drawing, and as shown in FIGS.
Coincides with the opening 35 and opens.

FIG. 6 is a flow chart showing the operation process of the device of the present application, in which one discharge mechanism A is connected to one outlet b of the two-way switching valve 10 which is in communication with the inlet a. A state in which a part of the other discharge mechanism B is connected to the other outlet C in the communication state is shown.

Next, the operation of one discharge mechanism A connected to one outlet b in the communicating state will be described in detail.

When the user operates a cleaning switch (not shown) as usual after using the toilet, a certain amount of pressurized air is supplied from the pressurized air supply unit 22 to the cleaning water tank 24 by the switch signal. As a result, a predetermined amount of cleaning water from the cleaning water tank 24 flows into the cleaning pipe 4 via the conduit 23, and the cleaning water is ejected from the lower surface of the cleaning pipe to flow down the inner surface of the toilet 1 to collect the filth. At the same time, it flows into one of the outlets b of the two-way switching valve 10 in the communicating state, and the intake valve 12
Stop at the position.

Further, the suction valve 12 is temporarily opened by the switch signal of the cleaning switch, and the dirt retained at the position of the suction valve 12 is instantaneously branched by the negative pressure action described later. 13 is sucked, and the suction valve 12 returns to the closed state.

When the suction valve 12 is returned to the closed state, pressurized air is supplied to the branch pipe 13 and the guide pipe 15 via the air supply unit 19 and the pipe between the suction valve 12 and the discharge valve 14 is supplied. The inside is pressurized.

When the pressurization state reaches the set value, the pressure sensor 18 detects this state, and the discharge valve 14 is temporarily opened by the detection signal, and the waste is stored in the storage tank. 11 and the discharge valve 14 returns to the closed state.

On the other hand, in the other discharge mechanism B connected to the other outlet C in the non-communication state, the sluice valve 20 is opened by the switch signal for cleaning, and as described above, the pressurization is performed. The suction valve 1 in the closed state is operated by the operation of the negative pressure means 21 utilizing the Venturi effect accompanying the supply of air.
The inside of the pipe partitioned by 2 and the discharge valve 14 is made negative pressure, and when the negative pressure state reaches a set value, the pressure sensor 18 operates, and the gate valve 20 is closed by the detection signal.

That is, as is apparent from FIG. 6, in the two-way switching valve 10, the one outlet b in the communicating state.
One discharge mechanism A connected to the other discharge mechanism B connected to the other outlet C in the non-communication state during the series of operations from inhalation to discharge of the waste, the other discharge mechanism B being negative pressure. Be put in a state.

The discharge operation state of the waste in the discharge mechanism A and the negative pressure operation in the discharge mechanism B are alternately performed each time of use, and accordingly, one outlet of the two-way switching valve 10 in the communication state. The dirt flowing down from b is instantly subjected to the negative pressure action when the intake valve 12 is opened, and the branch pipe 1 is instantaneously operated.
3 is inhaled.

The switching operation of the two-way switching valve 10 is performed by one of the discharge mechanism A, which is one of the operation signals from when the discharge valve A closes the suction valve 12 to suck the filth until the discharge of the filth. Signal associated with valve 12 closing or exhaust valve 1
4 may be performed by reversing the servomotor 9 by the signal associated with the opening or closing of the valve, but an entry signal for detecting that the user has entered the toilet room, for example, a signal associated with locking the door when entering the room. Alternatively, a detection signal for detecting entry into the room by a photoelectric switch or the like or a signal by a pressure switch installed on the floor of the toilet room or on the tread may be used.

In the above, when the filth sucked by the branch pipe 13 by the negative pressure action is transferred to the guide pipe 15, the filth is guided from the smaller diameter to the larger diameter by the connecting pipe 16, so that the filth does not get stuck. The branch pipe 13 smoothly moves to the guide pipe 15.

The filth that has flowed into the guide pipe 15 is
Two annular portions 15 that are spirally curved by the action of pressure
While flowing down while turning a and 15b, especially the annular portion 1
Since 5a is curved in the vertical direction, a strong swirling flow is generated, and this swirling flow and the pressurizing action in the pipe combine to generate a large flow inertia, and the filth flows down vigorously, It is discharged to the storage tank 10.

The opening / closing operation of the intake valve 12, the discharge valve 14 and the sluice valve 20 and the reversal operation of the two-way switching valve 10 are performed by supplying pressurized air to the air supply unit 19 and the wash water tank 24.
The operation of the negative pressure means 21 is automatically controlled by an electric control circuit including a solenoid valve.

By the way, in the above-mentioned embodiment, two discharge mechanisms are provided in parallel, and when one discharge mechanism is in operation from suction to discharge of the waste, the other discharge mechanism is set to the negative pressure state, The case where the two discharge mechanisms are relatively alternately used has been described, but in the configuration including the two discharge mechanisms, when some trouble occurs in one discharge mechanism and the discharge function of the waste material disappears, the other discharge mechanism disappears. The discharge mechanism can be used to accomplish the work of discharging the waste without any trouble.

Specifically, for example, in FIG. 6, a trouble occurs in the one discharge mechanism A connected to the one outlet b of the two-way switching valve 10 in the communicating state, so that the function of sucking or absorbing the filth is increased. When the function of supplying compressed air is disabled, or when dirt is retained, the two-way switching valve 10 is switched to the other outlet c side by the servomotor 9 or manually, and the inlet a and the outlet are connected. In addition, the automatic switching control circuit of the two-way switching valve 10 is cut off, the communication state between the inlet part a and the output part c is fixed, and
By operating the other discharging mechanism B side connected to the output portion c fixed in the communication state as follows, the discharge work of the waste can be achieved without any trouble.

That is, the sluice valve 20 is activated by the switch signal generated by the user's operation of the washing switch after the toilet is operated.
Is opened, and the inside of the pipe partitioned by the intake valve and the discharge valve 14 in the closed state is made negative pressure by the operation of the negative pressure means 21, and when the negative pressure state reaches the set value, The sluice valve 20 is closed by the operation of the pressure sensor 18, and the suction valve 12 is temporarily opened in accordance with this closing operation, so that the dirt is instantly sucked into the branch pipe 13, The same effect is performed.
