A water hose connection port 123, a blower hose connection port 124 communicating with the cleaning port 134a, and a connection terminal 127 are provided.

  As shown in FIGS. 2 and 3, a connecting member 19 to which one end of the filth suction hose 16, the washing water hose 17, the blower hose 18 and the electric wiring 128 is connected is detachably attached to the connecting portion 125. . When the connecting member 19 is attached to the connecting portion 125, the filth suction hose 16 is connected to the filth suction hose connection port 122, the cleaning water hose 17 is connected to the cleaning water hose connection port 123, and air is blown to the blower hose connection port 124. The hose 18 is connected, and the electrical wiring 128 is connected to the connection terminal 127.

  Wash water is supplied from the excrement disposal apparatus 14 to the wash ports 130a and 130b via the wash water hose 17. The cleaning port 130 a is provided at a position for spraying cleaning water toward the anus of the user 3 and is used for cleaning the anus of the user 3. The cleaning port 130b is provided at a position where the cleaning water is sprayed toward the genital area of the female user 3, and is used for cleaning the genital area of the female user 3. The cleaning ports 130a and 130b are constituted by a plurality of small-hole openings (not shown), and the cleaning water supplied to the cleaning ports 130a and 130b is sprayed to a relatively wide range.

  Further, the filth suction port 130c is provided at substantially the same height as the tray surface 40a of the tray section 40, and is used for suctioning excretion water and excrement on the tray surface 40a.

  The cleaning port 134a is provided on the waist side of the anus of the buttocks 3a, for example, at a position facing the vicinity of the caudal bone, and air supplied from the blower hose connection port 124 (including air mixed with cleaning water). Is released toward the vicinity of the bone. According to this, discharge | released air flows through the clearance gap between the collar part 3a and the tray surface 40a in the direction (X direction in a figure) which goes to the filth suction port 130c via the anal vicinity.

  The tray surface 40a is provided with a sewage reservoir 50 for storing a predetermined amount of water. The sewage reservoir 50 is located at a position facing the heel part 3a of the user 3, more specifically, an area between the cleaning port 134a and the filth suction port 130c, where excreted water such as excreted urine is discharged. It is provided at a position where it tends to accumulate, for example, a position facing the vicinity of the anus. For example, the sewage reservoir 50 has a volume in which moisture below the expected amount of water (urine etc.) contained in excreta, in other words, a small amount of water such as water remaining at the time of previous washing and sweat of the user 3 is retained. It is formed in a hollow shape having a volume that does not overflow when accumulated.

  A moisture detection sensor 217 constituting moisture detection means is disposed around the sewage reservoir 50, and the moisture detection sensor 217 includes a plurality of conduction detection terminals 217a, 217b, 217c, and 217d. The resistance value between the two terminals of the detection terminals 217a to 217d is configured to be able to detect the presence or absence of moisture from the resistance value between the terminals by utilizing that the resistance value between the two terminals becomes low when the terminals conduct through the moisture. ing. These continuity detection terminals 217a to 217d are arranged at positions facing each other across the sewage reservoir 50 as shown in a top view in FIG. The number of continuity detection terminals may be any number as long as it is two or more, and the position of each continuity detection terminal is not limited to the facing position, and is arranged around the sewage reservoir 50 with an interval. Any position within the range may be used.

  According to this, since the sewage reservoir 50 is provided in the region between the continuity detection terminals 217a to 271d, the continuity detection terminals 217a to 271d are located higher than the bottom 50a of the sewage reservoir 50, and the sewage reservoir 50 If the moisture is not fully accumulated, none of the conduction detection terminals 217a to 271d conducts, and the moisture detection sensor 217 does not detect moisture. For this reason, in the case of water remaining at the time of previous washing or a small amount of water such that the user 3 sweated, the moisture detection sensor 217 does not detect moisture, and the user 3 removes the urine from the reservoir 50. The moisture is detected by the moisture detection sensor 217 only when there is an overflowing amount of moisture.

  The continuity detection terminals 217a to 271d are connected to a connection terminal 127 provided in the connection part 125 via an electric wiring (not shown), and the connection terminal 127 is connected to the electric wiring 128 as described above.

It supplies in the diaper 12 via. The deodorizer / sterilizer 207 deodorizes / sterilizes the air sucked from the excretion tank 200 and supplies the deodorized / sterilized air into the diaper 12.

  A branch pipe 144 is connected between the air pipe 143 and the air pipe 145. The branch pipe 144 branches in two directions via the air pipe 150, the two-way valve 218, the air pipe 151, and the branch pipe 170. One is connected to the wash water tank 210 via the water pipe 149, the water pump 215 and the water pipe 148, and the other is connected to the wash water hose 17 via the water pipe 152.

  The wash water tank 210 is a tank in which wash water supplied into the diaper 12 is stored, and includes a hot water heater 211, a thermistor 212, and a float sensor (water level meter) 213. The hot water heater 211 warms the wash water in the wash water tank 210, the thermistor 212 detects the temperature of the wash water, and the float sensor (water level meter) 213 washes the wash water tank 210. It is for detecting the amount of water. Further, a water pipe 147 is connected to the bottom of the wash water tank 210, and when the drain cock (stopcock) 214 provided in the middle of the water pipe 147 is opened, the wash water in the wash water tank 210 is discharged to the outside. Is done.

  Moreover, the excrement disposal apparatus 14 is provided with the control part 220, the memory | storage part 230, and the resistance measurement part 240, and the control part 220 controls the excrement disposal apparatus 14 whole, A memory | storage part Reference numeral 230 denotes a data rewritable memory such as a flash memory, which stores programs read by the control unit 220 and executed, various data, and the like. In addition, the resistance measurement unit 240 is connected to the continuity detection terminals 217 a to 217 d of the moisture detection sensor 217, measures the resistance value between the continuity detection terminals 217 a to 217 d, and outputs the measurement result to the control unit 220.

  The excrement disposal apparatus 14 is provided with an operation panel 300 that is operated by an operator (including the user 3) to notify various information. FIG. 9 is a diagram illustrating an example of the operation panel 300. In this operation panel 300, the power switch 300a is a push-type switch for instructing the power on / off of the excrement disposal apparatus 14, and the automatic operation switch 300b is disposed on the diaper 12 regardless of the operation of the operator. On the basis of the signal from the moisture detection sensor 217, this is a push-down switch for instructing automatic execution of a series of excrement disposal steps including a suction step, a washing step, and a draining step. The operation mode lamp 300e is a manual mode in which the operation mode of the excrement disposal apparatus 14 operates according to the operation of the remote controller 302 or an automatic mode that operates based on a signal from the moisture detection sensor 217. This is a display lamp for notifying that.

  The hot water setting switch 300 c is a push-down switch for setting the temperature of the cleaning water stored in the cleaning water tank 210. The display panel 300f displays the set temperature while the warm water setting is being performed by operating the warm water setting switch 300c, and based on the detection value of the thermistor 212 other than the warm water setting. Displays the current wash water temperature. The water supply lamp 300g is a display lamp for notifying that the amount of cleaning water stored in the cleaning water tank 210 is insufficient, and the hot water lamp 300i does not reach the set temperature of the cleaning water. This is a display lamp for notifying that. The full lamp 300h is a display lamp for notifying that the amount of excrement and sewage stored in the excretion tank 200 exceeds a predetermined amount.

  The excrement disposal apparatus 14 includes a remote controller 302 for an operator (including the user 3) to operate the excrement disposal apparatus 14 at hand. FIG. 10 is a diagram illustrating an example of the remote controller 302. The remote controller 302 includes a suction button 302a for instructing the start of the suction process, a cleaning button 302b for instructing the start of the cleaning process, and a stop button 302c for instructing the end of the suction process and the cleaning process. In response to this, various instruction signals are transmitted to the control unit 220 of the excrement disposal apparatus 14 by wire or wireless.

  Next, operation | movement of this excrement disposal system 1 is demonstrated. As described above, the excrement disposal system 1 has, as operation modes, a manual mode that operates according to the operation of the remote controller 302 and an automatic mode that operates based on a signal from the moisture detection sensor 217. . This operation mode shifts to the automatic operation mode when the automatic operation switch 300b of the operation panel 300b is pressed, and shifts to the manual mode when the automatic operation switch 300b is pressed again in the automatic operation mode.

  Moreover, the control part 220 of the excrement disposal apparatus 14 is provided with the liquid level sensor 201 provided in the excretion tank 200 and the float sensor provided in the washing water tank 210 while the excrement disposal apparatus 14 is powered on. (Water level meter) 213 checks the amount stored in each tank. When the excretion tank 200 is full, the full lamp 300h is controlled to be turned on. When the cleaning water tank 210 needs to be supplied with cleaning water, the water supply lamp 300g is turned on. In addition to the control, the temperature of the cleaning water in the cleaning water tank 210 is detected by the thermistor 212, and a check process for controlling the driving of the hot water heater 211 so that the temperature of the cleaning water becomes the set temperature is appropriately executed.

  FIG. 11 is a flowchart showing the operation in the automatic operation mode.

  In the automatic operation mode, the control unit 220 first causes the resistance measurement unit 240 to measure the resistance value between the continuity detection terminals 217a to 217d of the moisture detection sensor 217, and based on the measured resistance value, the moisture detection sensor 217. Whether or not moisture has been detected is determined (step S1). More specifically, the control unit 220 determines whether or not the resistance value between the continuity detection terminals 217a to 217d is within a predetermined setting range Z1, and if any of the resistance values is within the setting range Z1. For example, it is determined that the moisture is detected by the moisture detection sensor 217.

  This setting range Z1 is a range that covers a resistance value that can be taken when the urine or other moisture is interposed between the terminals of the conduction detection terminals 217a to 217d. For example, the resistance value in the conduction state is non- Since it becomes lower than the resistance value in the conductive state, if the maximum resistance value in the conductive state is Y [Ω], the predetermined range may be a range of Y [Ω] or less.

  When moisture is not detected, the controller 220 repeats the process of step S1 at a predetermined cycle until moisture is detected. On the other hand, when moisture is detected, the controller 220 starts a suction process for sucking excrement such as urine excreted in the diaper 12 (step S2).

  Specifically, the control unit 220 operates the blower blower 205 and opens the two-way valve 28 to suck out the air in the excretion tank 200 and is connected to the excretion tank 200 via the filth suction hose 16. The inside of the diaper 12 is kept at a negative pressure, and the air sucked from the excretion tank 200 is supplied to the blower hose 18 through the air pipe 143, the branch pipe 144 and the air pipe 145, and the inside of the diaper 12 is washed. Air is blown into the diaper 12 through the mouth 134a. As a result, an air flow is formed in the diaper 12 from the cleaning port 134a toward the filth suction port 130c.

  Further, the control unit 220 drives the water pump 215 for a predetermined time, supplies the cleaning water stored in the cleaning water tank 210 to the position of the water pipe 148, and supplies the cleaning water through the branch pipe 170 and the two-way valve 218. The air flows into the air pipe 145, is mixed with the air flowing through the air pipe 145, and is discharged into the diaper 12 from the cleaning port 134 a. In this configuration, the cleaning ports 130a and 130b are formed in a plurality of small-hole openings, while the cleaning port 134a has a large opening area, and therefore, the conduit from the cleaning port 134a to the branch pipe 170 The pressure loss is lower than the pressure loss of the pipe line from the cleaning ports 130a and 130b to the branch pipe 170, and the wash water flows into the air pipe 145 due to this pressure loss difference and the negative pressure due to the air flowing through the air pipe 145. Because it is drawn.

  By discharging the air mixed with the washing water into the diaper 12, the excrement excreted in the diaper 12 is softened and easily flows, and the excrement is directed from the cleaning port 134a to the filth suction port 130c. 5 can be reliably sucked into the filth suction port 130c by the air flow in the X direction. The excrement sucked into the filth suction port 130 c is stored in the excretion tank 200 through the filth suction hose 16.

  In this configuration, since the sewage reservoir 50 is provided in the vicinity of the moisture detection sensor 217 provided in the tray unit 40, the moisture detection sensor 217 absorbs moisture when the amount of moisture is small enough to accumulate in the sewage reservoir 50. A malfunction that starts the suction process in response to a small amount of moisture without detection is prevented. For this reason, the suction process can be started only when the user 3 excretes a relatively large amount of water such as urine.

  After starting the suction step, the control unit 220 measures each resistance value (hereinafter referred to as “resistance value R”) between the conduction detection terminals 217a to 217d of the moisture detection sensor 217 by the resistance measurement unit 240 at a predetermined cycle. Then, it is determined whether or not the amount of change in one of the resistance values R (for example, the change rate or difference value of the measurement cycle interval) is within a predetermined setting range Z2 (step S3).

  Here, FIG. 12 is a characteristic curve diagram showing a change in the resistance value R in the suction process during excretion (feces and urine) excretion. As shown in this figure, for a period of time from the suction start time t1, since excrement is present in the vicinity of the conduction detection terminals 217a to 217d in addition to the washing water, the resistance value R becomes a relatively high value, and the time t is As the excrement is aspirated over time, the resistance value R gradually decreases, and when it reaches the time te when all excrement is aspirated, there is only wash water between the conduction detection terminals 217a to 217d. The resistance value R converges to a substantially constant value.

  The setting range Z2 is a value when there is almost no amount of change in the resistance value R. For example, when the rate of change is applied as the amount of change in the resistance value R, the setting range Z2 is around a value close to 1.0. Set to range. When determining that the amount of change in the resistance value R is within the set range Z2, the controller 220 closes the two-way valve 218 and ends the suction process (step S4).

  In the illustrated example, the resistance value R converges to a substantially constant value Ra after all the excrement has been aspirated. Therefore, by detecting that the detected resistance value R has reached this value Ra, excretion is achieved. Although it seems that it is possible to detect that all objects have been aspirated, this converged value Ra is a value that varies depending on the individual sensitivity of the moisture detection sensor 217 and variations in detection sensitivity depending on the degree of deterioration. Even if the resistance value R becomes the value Ra, excrement may remain.

  As described above, in this configuration, since the timing at which the resistance value R converges to a substantially constant value is detected based on the amount of change in the resistance value R, it is possible to accurately detect the timing at which almost all the excreta has been aspirated. it can. For this reason, by completing the suction process at this timing, the suction process can be ended as soon as all the excrement is sucked, for example, compared to the conventional one in which the suction time is set to a constant value. It becomes possible to eliminate the waste of washing water and electricity.

  When the suction process is completed, the control unit 220 starts a cleaning process for cleaning each part of the user 3 (step S5). In the cleaning process, the controller 220 first operates the blower blower 205 to form an air flow in the diaper 12 from the cleaning port 134a toward the filth suction port 130c. Next, the control unit 220 starts the operation of the water pump 215, and the cleaning water stored in the cleaning water tank 210 passes through the water pipe 148, the water pipe 149, the branch pipe 170 and the cleaning water hose 17, and the cleaning port 130 a of the diaper 12. , 130b. Each part of the user 3 is cleaned by the cleaning water sprayed from the cleaning ports 130 a and 130 b, and the cleaned cleaning water is sucked from the filth suction port 130 c and stored in the excretion tank 200. In this case, the wash water stored in the wash water tank 210 is washed without causing discomfort to the user 3 because the temperature of the wash water is adjusted to an appropriate temperature by the hot water heater 211 under the control of the control unit 220. be able to.

  Then, when the preset cleaning time has elapsed since the start of the cleaning process, the control unit 220 stops the water pump 215 to end the cleaning process, and drains the cleaning water accumulated in the cleaning water hose 17. The process is started (step S6). The cleaning time is set to a time that can be sufficiently cleaned or an arbitrary time set by the user 3 or the like.

  In this water draining process, the control unit 220 opens the two-way valve 218 and operates the blower blower 205, so that a part of the exhaust air from the blower blower 205 is diverted to the branch pipe 144, the air pipe 150, and the two-way. The cleaning water hose 17 is supplied through the valve 218, the air pipe 151, the branch pipe 170, and the water pipe 152, and the cleaning water accumulated in the cleaning water hose 17 is discharged. The discharged washing water is sucked from the filth suction port 130 c and stored in the excretion tank 200. Thereby, it is possible to prevent the low-temperature water accumulated in the washing water hose 17 from being discharged toward the user 3 during the next washing process. The above is the operation in the automatic operation mode. The operation in the manual mode is different only in that the suction process, the cleaning process, and the draining process are individually started or stopped according to the operation of the remote controller 302.

  As described above, in the excrement disposal system 1, the sewage reservoir 50 is provided in the vicinity of the moisture detection sensor 217 arranged on the tray portion 40 in which the surface 40 a facing the collar portion 3 a is formed as a flat surface. Thus, it is possible to avoid the case where the moisture detection sensor 217 detects a small amount of moisture, and it is possible to detect only a relatively large amount of moisture such as urine excreted by the user 3. As a result, it is possible to avoid a malfunction in which the moisture detection sensor 217 starts the suction process in response to a small amount of moisture. In this way, by avoiding malfunctions in the suction process, it is possible to save electricity costs and cleaning water.

  Further, in this embodiment, when the excrement suction operation is started, the amount of change in the resistance value between any of the conduction detection terminals 217a to 217d disposed on the tray surface 40a facing the buttocks of the diaper 12 is approximately. By stopping the suction operation when it becomes constant, the suction operation can be stopped at the timing when all the excrement has been sucked. That is, the excrement disposal system 1 can change the aspiration time according to the type (feces or urine) and the amount of excrement, and can stop the aspiration operation at an appropriate timing after aspiration. . Accordingly, wasteful supply of cleaning water can be avoided even after the suction is completed, so that water saving of the cleaning water and saving of electricity costs can be further achieved. In this case, the cleaning water replenishment interval to the cleaning water tank 210 can be increased, the usability is improved, and the cleaning water tank 210 does not need to be enlarged, so that the excrement disposal apparatus 14 can be downsized. .

  Although one embodiment of the present invention has been described above, the present invention is not limited to this, and various design changes can be made within the scope of the present invention.
