As shown in FIG. 10, the former has a tray-shaped toilet 101 made of a plastic molded product having a C-shaped side surface and an oval front surface with a concave center, and the tray-shaped toilet 101 has an opening rim. In addition to providing an elastic edge 104, a suction port 105 at the lower end, and a blow port 106 at the center,
An elliptical washing water discharge pipe 108 having small holes 107 scattered along the elastic edge 104 is provided slightly inside thereof.

[0003] The excrement is received by the tray-shaped toilet 101, and the waste is sucked by a suction hose 122 connected to the suction port 105.
The hot water supplied from the water supply hose 123 and discharged from the purified water discharge pipe 108 flows from above to wash the crotch, and the crotch is dried by the hot air supplied from the blower hose 124 and coming out of the blower opening 106.

On the other hand, the technique disclosed in Japanese Patent Publication No. 62-2535 discloses a negative pressure generating device capable of sucking both solid and liquid substances, and a suction edge which sucks the skin around a local area by the negative pressure. And a toilet provided with a nozzle for injecting washing water into the toilet, and the waste discharged in the toilet is discharged by the negative pressure generator.

[0005]

However, in the excrement disposal apparatus of this type in which the waste is sucked from the suction port of the cup unit for collecting urine and stool, the suction force is too strong to remove the cup unit from the crotch. There has been a problem in that anxiety about whether the patient is gone or hurt is given to a sick person or the like who uses it. In particular, the technique disclosed in Japanese Patent Publication No. 62-2535 uses the toilet itself by adsorbing it on the skin of the local area. Therefore, if the negative pressure of the negative pressure generator that sucks the waste is increased, the suction of the waste becomes complete. However, on the other hand, there is a risk that the prolapse and / or cavity will occur, which may have a bad effect on the human body, so that a large negative pressure cannot be obtained. The present invention has been made in view of the above, and it is an object of the present invention to provide an excrement disposal apparatus that does not cause inconvenience such as the cup unit not being able to be removed from the crotch portion even if the suction force is increased.

FIG. 8 shows a portion of the washing water jet nozzle, and shows the portions of the washing water jet nozzles 27 and 28 in an enlarged manner.
Among them, the washing water jet nozzle 27 located at the upper position is for women, and jets washing water that spreads in a fan shape in a vertical plane from the upper part of the urethral opening toward the lower part of the urethral opening. The spouting angle of the fan shape for women varies depending on the jetting pressure and jetting amount of the cleaning liquid, but is about 60 ° to 100 °. On the other hand, the washing water ejection nozzle 28 located at the lower level is for men and is directed to the anus, but ejects linearly with little or no ejection spread.

A hot water supply mechanism for ejecting washing water from the washing water ejection nozzle will be described with reference to FIG. In FIG.
The distal end of the cleaning hose 8 is connected to one of the connection ports 27b and 28b of the cleaning water jet nozzles 27 and 28 (the connection port is set in advance according to the gender of the patient to be used, and the connection port of the unused one is not shown). The back end of the washing hose 8 is connected to the washing water tank 7 at a level below the washing water level. This washing water tank 7 has a heater at the lower part and functions as a hot water tank.

An exhaust pipe 62 of a vacuum pump 6 is connected above the liquid level of the wash water in the wash water tank 7 as a supply pressure source of the wash water.
The warm water in the washing water tank 7 is discharged to the washing hose 8 by the exhaust pressure of the vacuum pump 6 given through the pump 3. That is, the vacuum pump 6 functions as a water supply pump, and causes the cleaning water stored in the cleaning water tank 7 to be jetted from the cleaning water jet nozzles 27 and 28.

In this embodiment, the on-off valve 6 is connected to the exhaust pipe 62.
An open pipe 65 is provided through the fourth pipe 4. Therefore, the on-off valve 63 is operated so that the washing water is not blown out, and the exhaust pipe 6 is operated.
2 is closed, the on-off valve 64 and the open pipe 65
The exhaust gas is exhausted through this, and the vacuum pump 6 can be driven normally. Further, the cleaning hose 8 has a second on-off valve 7.
1 is provided, and by closing the second opening / closing valve 71, the supply of the cleaning water and the pressurization in the cleaning water tank 7 can be performed.

Next, the waste suction mechanism will be described with reference to FIGS. 2, 3 and 9. The tip of the waste hose 3 is connected to the waste suction port 26, and the rear end of the waste hose 3 is connected to the waste tank 5 via a large-diameter first pinch valve 41 described later. Then, as shown in FIG. 12, a vacuum pump 6 functioning as a suction pump is connected to the waste tank 5 by a connection pipe 61.

The pinch valve unit 4 is provided with a large-diameter first pinch valve 41 interposed between the waste hose 3 and the waste tank 5 and a residual water in the waste hose 3 in the middle of the waste hose 3. And a small-diameter second pinch valve 45 for sucking through the residual water suction tube 31 from the residual water suction tube 30 interposed therebetween. In addition, the pinch valve 4
1 and 45 are configured to open and close the passages of the respective waste hoses 3 and the residual water suction tube 31 by operating the control valves 480 and 490.

The control device 90 shown in FIG. 9 opens the on-off valve 71 before use, and supplies the washing water from the nozzle 27 to the storage section 2.
3 to close the bottom communication port 23a with the washing water, open the pinch valve 41 after use, and suck the dirt in the storage unit 23 composed of the washing water and excrement from the dirt suction port 23a to the dirt tank 5. Construct control means.

Next, the operation of the above configuration will be described step by step with reference to FIG. (1) Blockage of Bottom Contact Port 23a by Stored Water First, wash water is supplied into the storage unit 23 of the cup unit 2 to cause the inside of the storage unit 23 to be closed at the bottom rear end.
To the level at which is closed. This is performed as follows.

When the "start operation" button on the remote controller 10 is pressed, the pinch valves 41 and 45 are "closed" (the control valves 480 and 490 are "open"), and the first on-off valve 63 and the second on-off valve 71 are "on". The vacuum pump 6 is driven in the "open" state. Since the exhaust pressure of the vacuum pump 6 is sent to the washing water tank 7,
The pressure in the washing water tank 7 is increased, and at that pressure, the washing water (hot water) in the washing water tank 7 is discharged to the washing water jet nozzle (in this embodiment, the washing water jet for women in this embodiment). It flows out of the nozzle 27). Therefore, the washing water jet nozzle 27 functions as a water supply port for the storage unit 23 here.

When a predetermined amount of washing water accumulates in the reservoir 23 of the cup unit 2 and the bottom communication port 24 is closed by the accumulated water, the second on-off valve 71 is closed. Therefore,
By closing the second on-off valve 71, the supply of the washing water is stopped, and the inside of the washing water tank 7 is pressurized to a predetermined pressure slightly higher than before.

(2) Washing After excretion, by pressing the “washing start” button on the remote controller 10, the second opening / closing valve 71 is opened again, and the washing water (hot water ) Is sent out to the washing hose 8 and spouted vigorously from the washing water ejection nozzle 27 for women. The jetted washing water is shown in FIG.
As described in the above, warm water spreads flat and fan-shaped in a vertical plane from the upper part of the urethral opening to the lower part of the urethral opening, and the crotch is widely washed, and the woman is washed widely from the urethral opening to the anus. be able to. Therefore, compared to the type in which the washing water is allowed to flow down from above, the contaminated washing water after washing does not flow into the urethral opening, etc., and therefore, Escherichia coli etc. enter the urethral opening, etc. And the like can be prevented.

(3) Suction by Soil Hose After the above-mentioned washing, by pressing the “suction start” button of the remote controller 10, the suction of the sewage by the sewage hose 3 and the remaining water suction tube 31 that follows. Residual water suction is performed.

First, of the control valves 480 and 490,
By operating the control valve 480, the space up to the bottom communication port 23a of the storage unit 23, which is closed with the filth consisting of the filth hose 3, the washing water and the excrement, becomes a negative pressure at once, and the large negative pressure is temporarily applied to the filth. Therefore, the waste is completely sucked from the storage unit 23.

At this time, the concave chamber 22 of the cup unit is
The passage 29 of the handle 24 is continuous from the upper part of the inner surface to the lower part of the inner surface and communicates with the atmosphere. Therefore, there is no danger that the concave chamber 22 will be extremely negatively pressured when sucking dirt.
In addition, since the sick person or the like can remove the cup unit from the crotch at any time, the danger caused by suction can be completely wiped off.

Next, in order to remove residual water remaining in the waste hose 3, the control valves 480 and 490 are set to “open”, and after the degree of vacuum in the waste tank 5 is increased, the control valve 49 is opened.
0, the joint portion of the residual water suction tube 31 is opened at the bottom or lower part of the residual water suction tube 30 so that even the lowest level of residual water in the tube is closed by this. Therefore, the space up to the opening of the residual water suction pipe 30 closed with the residual water becomes a negative pressure at a stretch, and the residual water is completely removed by suction at a large negative pressure. The negative pressure generated at this time also communicates with the atmosphere through the passage 29 in the same manner as described above, thereby preventing the inner cover 2b from being attracted.

In the above embodiment, the passage is formed as an air introduction hole. However, the air introduction hole is not limited to this, and one or a plurality of holes may be provided at other portions of the cup unit. May be. Further, the check valve is not limited to the configuration of the embodiment, but may have an appropriate configuration.

[0031]

As described above, according to the present invention,
The concave chamber of the cup unit is continuous from its upper inner surface to its lower inner surface and projects from the back of the cup unit.
It communicates with the atmosphere by a letter-shaped handle. As a result, when sucking the dirt in the storage part from the dirt suction port, the danger that the concave chamber becomes extremely negative pressure can be surely avoided. In addition, the presence of the handle allows the sick person or the like to have a sense of security that he / she can remove the cup unit from the crotch at any time, thereby completely eliminating the danger.
