A pipe 106 is connected to the COM port of the electromagnetic switching valve 78, and a branching T joint 108 is provided at the tip of the pipe 106. The holes 32 and 34 are connected.
[0018]
Next, the operation during cleaning will be described. First, the attachment tool 4 is attached to the crotch portion of the human body, and a belt member such as a band or a string (not shown) is applied to the belt recesses 16a and 18a so that the attachment tool 4 is firmly attached to the human body. Let In this state, the surface portion 36 of the wearing tool 4 is in close contact with the human body, and the water or the like inside does not leak.
[0019]
This automatic excrement disposal apparatus 2 normally operates only with the small pump 50, and the large pump 48 is turned off and is not operated. The large pump 48 is activated and the small pump 50 is powered off only when the timer, which is a cleaning operation, is ON, or only on a remote controller (not shown).
[0020]
Except at the time of cleaning, the small pump 50 is operated, and the air in the excreta tank 6 is sucked through the flexible hose 43, the joint 45, and the pipe 82 as shown in FIG. Is sent to the pipe 87 through the electromagnetic switching valve 68. Air from the pipe 87 is warmed to the same temperature as the washing water by the air pipe 60 in the washing water tank 8 and sent to the pipe 104. Then, warm air is sent from the cleaning nozzles 32 and 34 through the piping 106 via the electromagnetic switching valve 78. The air sent into the mounting device 4 is sucked from the excrement suction port 28 and the air bypass port 30, passes through the suction hose 35 and the flexible hose 37, and then passes through the excretion suction hole 40 and the air suction port 44 to the excretion tank 6. Sucked in. Thereby, the inside of the wearing tool 4 is always kept in a properly dried state.
[0021]
Moreover, the removal suction operation of the excretion 38 excreted in the processing recess 22 of the wearing tool 4 is performed periodically by a timer or at any time by remote control operation. During the cleaning operation, the small pump 50 stops, the port of the electromagnetic switching valve 68 is switched, and the large pump 48 performs suction and air supply. Due to the operation of the large pump 48, the inside of the excrement tank 6 becomes more negative pressure, and excrement is excreted together with the washing water through the excretion suction port 28, the flexible hose 35, and the excrement entrance hole 40 of the excretion tank 6. The material tank 6 is sucked and accumulated.
[0022]
At the same time, the air supply from the large pump 48 is sent to the electromagnetic switching valves 70 and 74, and the electromagnetic switching valves 70, 74 and 76 are switched from the state shown in FIG. As a result, the cleaning water in the cleaning water tank 8 is once sucked into the water supply cylinder 72, the electromagnetic switching valves 74 and 76 are brought into the state shown in FIG. 6, and the cleaning water is pushed out from the water supply cylinder 72 with a predetermined pressure. At this time, the electromagnetic switching valve 78 is switched from the state shown in FIG. As a result, the cleaning water is jetted from the cleaning nozzles 32 and 34 via the piping 98 and the flexible hoses 39 and 41 via the piping 98, the electromagnetic switching valve 76, the piping 100 and the electromagnetic switching valve 78.
[0023]
The washing nozzle 32 is for spraying washing water to wash the local part of the human body, and the washing nozzle 34 is located on the back side of the buttocks of the human body so as to flush the excrement toward the excrement suction port 28. A high-pressure jet is formed. The operation of the water supply cylinder 72 is performed an appropriate number of times, for example, about three times, and is repeated to the extent that the human body and the mounting tool 4 are reliably cleaned. Thereafter, the operation of the water supply cylinder 72 is stopped by the electromagnetic switching valve 74 and the electromagnetic switching valve 78 is switched to the state shown in FIG. 6, and a large amount of air heated by the air pipe 60 is piped 104, 106 by the large pump 48. After that, the cleaning nozzles 32 and 34 are fed into the wearing tool 4 for a predetermined time. When the above series of operations is completed, the large pump 48 is stopped and the operation is switched to the air circulation by the small pump 50 again.
[0024]
The level sensor 46 outputs a signal to a control unit (not shown) when the excrement 38 is full, and instructs to discard the excrement 38 in the excretion tank 6.
[0025]
In the automatic excrement disposal apparatus of this embodiment, the U-shaped attachment 4 is attached to and closely attached to the crotch portion of the human body, and the excrement is washed away inside. Since it is formed by, it is also good to wear. In addition, since the large pump 48 serves as a sucking and drinking pump, and the small pump 50 is used for drying at all times, it consumes less energy and can supply and suck water sufficiently when necessary. Furthermore, when washing, the washing water can be jetted vigorously by the water supply cylinder 72, the excrement can be washed away reliably, and the human body can always be kept clean.
[0026]
【The invention's effect】
The automatic excrement disposal apparatus according to the present invention has a simple configuration and allows easy mounting of the wearing tool, and the apparatus can be made small. In particular, since it is a substantially U-shaped mounting tool, even a bedridden person can easily wear it, and the suction and washing of excreta accumulated in the internal processing recess are reliably performed. Further, the wearing tool can be used for a long time, and can be used many times after being washed. And the frequency | count of attachment / detachment of the diaper which a sick person, a bedridden elderly person, etc. dislike by this can be reduced significantly.
