These are for easy handling, chemical resistance,
Considering mass productivity, etc., it is made of plastic such as polypropylene resin.

One end of a pipe 14 for sucking urine and feces is attached to the bottom of the bottom cup 11c by a one-touch connection, and an intermediate portion 14a on the one end side of the pipe 14 is temporarily lifted to a position higher than the bottom cup 11c. .
An air bleeder 14b for bleeding air is provided above the high portion 14a. Water 10 can be put in the bottom cup 11c. The structure in which the part 14a in the middle of the pipe 14 is once raised is because the bottom cup 11c can sufficiently store the water 10 to facilitate urination and defecation, and the vacuum suction allows the inside of the bottom cup 11c to be easily removed. This is because when siphoning urine or feces, the siphon action surely and easily moves it to the waste tank 12 side.

The bottom cup 11c has a volume of, for example, about 150 mm and a height of 40 mm or more so that it can receive feces and the like and that it is easy to urinate and defecate with confidence. , Θ ₁ = 30 to 45 so that stool does not adhere and vacuum suction is easy

a was linked. It should be noted that it is possible to connect only the pipe 16 when it is used for women and to connect only the pipe 16a when it is used for men. If both pipes 16 and 16a are connected in advance,
It is advisable to provide a switching valve in the middle of the circuit. It should be noted that a heater may be built in the cup 11 so that the cup 11 feels slightly warm when it is applied to the human body. Further, a handle may be attached to the cup 11 in order to make the cup 11 easy to handle.

In the waste tank 12, the lid portion 12a is provided between the pipe portion 12b which can connect the pipe 14 to the central portion with one touch and the pipe portion 12b around the pipe portion 12b as shown in FIG. An inner cover portion 12c provided with a gap for vacuum suction and a suction port 12d to which the pipe 21 is connected with one touch are provided. The inner cover portion 12c is provided to prevent the waste 47 accumulated in the waste tank 12 from being sucked into the pipe 21 when vacuum suction is performed.

The pinch valves 15 and 19 are, for example, as shown in FIGS. 5 and 6, mainly composed of an outer rectangular main body 48 and a flexible opening / closing member 49 made of rubber or the like provided in the main body 48. Has become. Both ends of the opening / closing member 49 are fixed inside both ends of the main body 48, and in order to surely obtain the valve closed state, the central portion of the opening / closing member 49 has a uniform thickness and an elliptical cross section. The compressed air sent from the pipes 29, 30 connected to the side of the main body 48 via the joint 50 compresses the opening / closing member 49 in the direction of the elliptical minor axis so that the inside of the opening / closing member 49 is compressed. The passage can be closed. 5 and 6 show a state in which the passage is opened, that is, the valve is opened without applying compressed air, or conversely, vacuum suction is performed through the pipes 29 and 30.

The pipe 18 is attached to the connector 20 provided in the middle of the pipe 14, and the pipe 18 is attached to the pipe 14 immediately in front of the waste tank 12 via the pinch pipe 19 because the inside of the pipe 14 is sucked. In this case, the dirt and water in the pipe 14 are not completely sucked, and a part thereof remains as the residual water 51, so that the residual water 51 can be reliably and easily taken out. By doing so, it is hygienic and the life of the pipe 14 and the like can be extended.

It is possible to use general seat valves or ball valves instead of the pinch valves 15 and 19, but in order to prevent electric leakage, electricity is not used and dirt is not caught. The pinch valves 15 and 19 that open and close only by air pressure are optimal.

Next, the operation method and operation of the above-mentioned device will be described. First, as shown in FIG. 2, the human body 44 in a sleeping state
Put the cup 11 on the hips. Next, hand switch 41
Are operated to operate the switching valves 25 and 33, open the on-off valves 31 and 32, and from the compressed air supply source 28 into the pinch valves 15 and 19, for example, about 2 kg / cm ² regulated by the relief valve 27. Send compressed air and close the pinch valves 15 and 19 securely. Next, the on-off valve 22 is opened and the inside of the waste tank 12 is depressurized to, for example, about 400 mmHg by the action of the vacuum generator 23.

Next, with this state maintained, the switching valve 2
5 and the opening / closing valve 24a open, the upper portion of the cleaning tank 13 is regulated by a relief valve 26a, for example, about 0.2 k.
The compressed air of g / cm ² is supplied for a predetermined time, and the water 10 in the cleaning tank 13 is poured into the cup 11 through the pipe 16. At this time, since the water slightly overflows from the middle portion 14a of the pipe 14, the water 10 having a predetermined height is put in the cup 11 and is stored in a water-sealed state.

In this state, a person urinates and defecates. Then, urine and feces fall into the water in the cup 11. At this time, the bottom cup 11c of the cup 11 is filled with water, and since the inner surface is provided with an appropriate inclination, stool does not stick to the inner surface of the bottom cup 11c.

When urination and defecation are finished, the on-off valve 24 is opened,
For example, about 0.5 kg / cm ² regulated by the relief valve 26
Compressed air is supplied to the upper part of the cleaning tank 13 to eject water from the nozzle 45 or 46 to clean the hips and the female genital area. In addition, both pipes 1 are attached to the nozzles 45 and 46.
When 6, 16a are connected, a switching valve for men and women or an opening / closing valve for men can be provided in the circuit so that the women and the men can use them properly. It should be noted that by appropriately changing the pneumatic circuit and the hydraulic circuit, it is possible to separately wash the hips and the genital area.

After cleaning, the pinch valve 19 is kept closed, the switching valve 33 is actuated, and the compressed air pressing the opening / closing member 49 in the pinch valve 15 is sucked, whereby the pinch valve 15 is closed. Instantly open. Then, since the inside of the waste tank 12 is already kept in a depressurized state and the vacuum generator 27 is operating without change, the urine and feces in the cup 11 are sucked into the inside of the waste tank 12 all at once with water. To be done. Therefore, suction of this waste from the cup 11 is surely and easily performed. In addition,
If the compressed air is discharged from the pinch valve 15 to the atmosphere, it may not be sufficiently opened because the inside of the waste tank 12 has a negative pressure. When discharged, the pinch valve 15 is surely opened.

At the end of this operation, some residual water 51 remains in a part of the pipe 14. Therefore, next, after closing the pinch valve 15, the pinch valve 19 is opened to suck and take out the residual water 51 into the waste tank 12. If the waste 47 is taken into the waste tank 12, the waste tank 12 is appropriately removed and the waste 47 is thrown into the toilet.
