Further, in the following description, the "height direction" is the height direction of the excrement suction device 1 and corresponds to the vertical direction when the excretion suction device 1 is placed on a horizontal plane. Further, the "depth direction" is the depth direction of the excrement suction device 1, and specifically, corresponds to the longitudinal direction of the housing 31, which will be described later. Then, the side to which the suction hose 51 for sucking the excrement is attached in the "depth direction" is the front side, and the opposite side is the back side.

<< Configuration of excrement suction device according to this embodiment >>
First, the configuration of the excrement suction device (hereinafter, excrement suction device 1) according to the present embodiment will be described with reference to FIGS. 1 to 8.

The excrement suction device 1 has the appearance shown in FIG. 1 and is used for treating excrement of a patient who has difficulty walking or a bedridden elderly person (hereinafter referred to as user U).

As shown in FIGS. 1 and 2, the excrement suction device 1 includes a cup member 10 directly attached by the user U, a device main body 30, a suction hose 51 connecting the cup member 10 and the device main body 30, and a washing water hose 52. , The air return hose 53 and the signal transmission cable 54 are provided.

The suction hose 51 is a hose for sucking excrement. One end of the suction hose 51 (the end on the side connected to the cup member 10) penetrates the bottom wall of the cup member 10, and the space between the bottom wall of the cup member 10 and the crotch portion of the user. Facing. The other end of the suction hose 51 (the end opposite to the side connected to the cup member 10) is connected to the excrement container 20. The excrement D received by the cup member 10 on the bottom wall is conveyed to the excrement container 20 through the inside of the suction hose 51 when being sucked by the excrement suction device 1.

The wash water hose 52 is a hose for supplying wash water. The washing water hose 52 forms a flow path for washing water supplied from the washing unit 60 shown in FIG. One end of the wash water hose 52 (the end on the side connected to the cup member 10) penetrates the cup member 10, and the cup member 10 and the user's crotch portion (specifically, in the crotch portion). It faces the space between the part located on the dorsal side rather than the ventral side). Therefore, when the cleaning water is supplied from the cleaning unit 60, the cleaning water flows in the cleaning water hose 52 toward the portion of the user's body to which the cup member 10 is applied, that is, the crotch portion. Finally, it is ejected from the opening on one end side of the washing water hose 52 (specifically, the washing water nozzle 16).

As with the excrement D, the washing water ejected toward the user's body is received by the cup member 10, sucked through the suction hose 51, and transported to the excrement container 20.

The air return hose 53 is a hose for returning air. The air return hose 53 does not have a flow path for returning the air in the cup member 10 sucked together with the excrement D and the washing water to the cup member 10 again when the excrement D and the washing water are sucked through the suction hose 51. ing. One end of the air return hose 53 (the end on the side connected to the cup member 10) penetrates the cup member 10, and the cup member 10 and the user's crotch portion (specifically, in the crotch portion). It faces the space between the part located on the dorsal side rather than the ventral side). After the air sucked together with the excrement D and the washing water passes through the inside of the excrement suction device 1, the washing water is directed toward the part of the user's body to which the cup member 10 is applied, that is, the crotch part. It flows inside the air return hose 53. Finally, the air is discharged from the one-end side opening (specifically, the air outlet 14) of the air return hose 53.

That is, the air in the cup member 10 circulates between the inside of the cup member 10 and the inside of the device main body 30 of the excrement suction device 1. As a result, it is possible to keep the odor during defecation inside the cup member 10 and inside the device main body 30 of the excrement suction device 1 and suppress the odor from drifting to the outside as much as possible.

Further, the signal transmission cable 54 is a transmission path for transmitting a detection signal from the electrode unit 15 as a detection unit for detecting an object in the cup member 10 to the device main body 30 side of the excrement suction device 1. The above-mentioned "object" is, for example, excrement. Further, in the present embodiment, an example in which an electrode is used as the above-mentioned "detection unit" will be described, but the above-mentioned "detection unit" includes an electrode type sensor, a capacitance type sensor, an optical sensor, and heat. One type or a plurality of types of various sensors such as a sensing type sensor may be combined. In the present embodiment, by configuring the above-mentioned "detection unit" with electrodes, it is possible to reduce the cost and simplify the structure as compared with the case of using a plurality of types of sensors.
Then, the detection signal from the electrode unit 15 is input to the controller 80 that controls the operation of the excrement suction device 1 via the signal transmission cable 54.

Next, the configuration of the cup member 10 of the excrement suction device 1 and the outline of the operation of the excrement suction device 1 will be described.

As shown in FIG. 2, the user U attaches the diaper P from above the cup member 10 with the excretion site E covered with the cup member 10. Then, the user U excretes, for example, on his back or in a state where his upper body is slightly raised. Then, the excrement suction device 1 detects the excrement in the cup member 10 and determines the type of excrement. The type of excrement described above is stool (stool) or urine.

More specifically, as shown in FIG. 4, the cup member 10 is applied to the first cover member 11 that covers the excretion portion E of the user U and the portion of the buttocks of the user U that is located on the back side. 2 It has a cover member 12. The second cover member 12 extends in a direction that rises substantially vertically from the rear end of the first cover member 11, and the cup member 10 has a substantially L-shaped external shape in a side view.

The first cover member 11 has a receiving surface 11a for receiving the excrement excreted in the cup member 10 and a guiding surface 11b for guiding the excrement to the receiving surface 11a. A wall portion 11c that rises vertically from the receiving surface 11a and the guiding surface 11b and is in close contact with the human body when the cup member 10 is attached is formed around the receiving surface 11a and the guiding surface 11b. As a result, when the cup member 10 is attached, a closed space (hereinafter, excrement storage space) is formed by the human body, the receiving surface 11a, the guiding surface 11b, and the wall portion 11c. The user's excrement is temporarily stored in this excrement storage space.

As shown in FIG. 5, the receiving surface 11a of the first cover member 11 is provided with an electrode portion 15 composed of a plurality of electrodes 15c. The electrode portion 15 includes a first electrode pair 15a arranged at the center of the receiving surface 11a and a plurality of (three in this example) second electrode pairs 15b arranged around the first electrode pair 15a. Have. The first electrode pair 15a and the second electrode pair 15b each consist of a pair of two electrodes 15c, a positive electrode and a negative electrode, and are excreted when the excrement is in contact with the positive electrode and the negative electrode of the electrode pair. An object becomes a conductor, and an electric current flows through the electrode pair.
Here, each electrode 15c may be plated with a metal such as gold to enhance corrosion resistance.
Since the conductivity of the wash water and the excrement are different, it is possible to determine whether or not there is excrement on the receiving surface 11a based on the magnitude of the current value flowing through the electrode pair. The details of the excrement detection and the excrement type determination process will be described later.

Further, as shown in FIG. 5, by arranging the first electrode pair 15a at a position facing the anus of the user U, it becomes easy to detect the stool received by the receiving surface 11a. Further, three second electrode pairs 15b are provided around the first electrode pair 15a, and each second electrode pair 15b is arranged so as to be offset by an angle of approximately 120 degrees with respect to the first electrode pair 15a. This makes it easier to detect excrement regardless of the posture of the user U (rightward or leftward, supine or upper body). That is, when the posture of the user U changes, the angle of the receiving surface 11a with respect to the vertical direction changes, and the part on the receiving surface 11a where excrement is likely to be placed changes. It becomes possible to detect excrement in.

Then, when the excrement is detected by the electrode portion 15, the excrement suction device 1 starts the operation of the cleaning process and the operation of the excrement suction process. Hereinafter, a configuration for realizing the cleaning treatment and the suction treatment provided in the excrement suction device 1 will be described.

As shown in FIG. 5, a washing water nozzle 16 is provided on the wall portion 11c, and a washing water hose 52 is connected to the washing water nozzle 16. Then, the washing water supplied from the device main body 30 side of the excrement suction device 1 via the washing water hose 52 is hung from the washing water nozzle 16 to the user U (groin, pubic area) and its surroundings (buttocks, etc.). Then, wash away the excrement adhering to the excretion site E and its surroundings.
The washing water nozzles 16 may be provided at a plurality of locations along the wall portion 11c.

Further, as shown in FIGS. 4 and 5, an excrement suction port 13 is formed in the vicinity of the connection portion with the receiving surface 11a on the guide surface 11b of the first cover member 11. A suction hose 51 for sucking excrement is connected to the excrement suction port 13.
Then, the excrement suction device 1 sucks the excrement stored in the excrement storage space to the device main body 30 side of the excrement suction device 1 through the suction hose 51, and the excrement site E of the user after excretion and the excrement site E thereof. Sprinkle wash water around the area from the wash water nozzle 16. Here, the sewage containing excrement is temporarily stored in the excrement storage space, and then in the excrement container 20 set in the excrement suction device 1 through the excrement suction port 13 and the suction hose 51. It is sucked into the excrement container 20 and stored in the excrement container 20.

Further, as shown in FIG. 4, an air outlet 14 for blowing out air sent from the air return hose 53 is formed on the guide surface 11b. The air outlet 14 is a vent that circulates the air sucked together with the sewage through the suction hose 51 and returns it to the cup member 10. Then, after the cleaning of the excretion site E with the cleaning water is completed, the air blown out from the air outlet 14 is continued for a predetermined time, so that the excretion site E on which the cleaning water is applied and its surroundings can be dried at an early stage. ..

For example, the dust removal / deodorizing filter 23 may be a rectangular sheet-shaped filter, and the shape is not particularly limited. When the air in the excrement container 20 passes through the second suction port 20c, the component of the excrement D in the air is captured by the dust removal / deodorizing filter 23.

Further, in the upper part of the excrement container 20, a substantially oval through hole (hereinafter referred to as the first suction port 20b) is provided at the end opposite to the end where the second suction port 20c is formed. Has been done. The first suction port 20b is formed to suck the excrement D and the washing water into the excrement container 20. Further, as shown in FIG. 6, the end portion of the suction hose 51 (the end portion on the side opposite to the side connected to the cup member 10) enters the first suction port 20b.

Further, in the present embodiment, the suction hose 51 and the connector 32a can be easily inserted and removed from the excrement container 20 by opening and closing the first lid portion 32. Further, with such a configuration, when the end portion of the suction hose 51 is pulled out from the excrement container 20, it is difficult to apply an excessive force to the hose end portion. As a result, it is possible to avoid a situation in which the excrement D scatters from the opening of the hose end and contaminates the inside of the case unit 35 because an excessive force is applied to the hose end when the hose end is pulled out. Will be.

Then, when the blower 41 sucks the air in the case unit 35 with the first lid portion 32 closed and the end of the suction hose 51 reaching the inside of the excrement container 20, the inside of the excrement container 20 is depressurized. To. At this time, if the excrement D is placed on the cup member 10, the excrement D is sucked, moves in the suction hose 51, and is transported to the excrement container 20. Further, when the cleaning water is supplied from the cleaning unit 60 to the cup member 10, the cleaning water is also sucked into the excrement container 20 through the suction hose 51.

Specifically, the sucked excrement D and the washing water will drop by their own weight in the excrement container 20 when they pass through the tip opening of the end of the suction hose 51 that has entered the excrement container 20. It accumulates in the same tank. On the other hand, the air sucked together with the excrement D and the washing water is separated from the excrement D and the washing water by the excrement container 20, and is discharged to the outside of the tank from the second suction port 20c of the excrement container 20 and blower. It is sucked into 41.

The excrement container 20 is removed from the case unit 35 when a predetermined amount or more of excrement and washing water are accumulated inside the excrement container 20. That is, the excrement container 20 is removable from the case unit 35. More specifically, by opening the closed first lid portion 32, the end portion of the suction hose 51 is pulled out of the excrement container 20 and the upper end opening of the case unit 35 is opened. After that, when the excrement container 20 is lifted upward while grasping the handle 20a of the excrement container 20, the excrement container 20 can be removed from the case unit 35.

As described above, in the present embodiment, the air sucked into the excrement container 20 together with the excrement D and the washing water is the internal space of the excrement container 20 (particularly, the upper portion in the internal space). ), And is discharged out of the excrement container 20 through the second suction port 20c. Here, when the air moves in the excrement container 20, the moving speed (flow velocity) of the air becomes slower than in the case where the air moves in a general pipe or hose. This makes it easier to separate the air from the excrement D and the washing water in the excrement container 20.

Further, the air that has flowed out of the excrement container 20 from the second suction port 20c moves inside the case unit 35 and heads toward the intake port 36. Eventually, the air passes through the suction filter 37 in the case unit 35, then moves from the inside of the case unit 35 into the blower casing 43 through the intake port 36, and is sucked into the blower 41 in the blower casing 43. As described above, in the present embodiment, the second suction port 20c of the excrement container 20 and the intake port 36 of the case unit 35 have a part of the space in the case unit 35 interposed therebetween. , Separated from each other. That is, in the present embodiment, the second suction port 20c and the intake port 36 are not directly connected, and the pipe or the like connecting the second suction port 20c and the intake port 36 is not provided.

Since the space is provided between the second suction port 20c and the intake port 36 as described above, the air that has flowed out of the excrement container 20 from the second suction port 20c is once placed in the above space. After being released, it will be sucked into the blower 41 through the intake port 36. As a result, when the blower 41 inhales the air in the excrement container 20, water (mist water derived from the excrement D and the washing water), bacteria in the excrement D, and the like are sucked together with the air, and the blower 41 is sucked. It is possible to prevent the air return hose 53 and the like from being contaminated.

As described above, the air that has come out of the excrement container 20 is once released into the case unit 35, so that the air is temporarily mixed with water, bacteria, etc. and is outside the excrement container 20. Even if it appears in the case, it is possible to store water, bacteria, etc. in the case unit 35. That is, in the present embodiment, it is possible to suppress the expansion of the contaminated portion.

Further, in the present embodiment, by making the circulation path of the excrement suction device 1 compact, the pressure loss when air flows in the device is also suppressed to a small size. As a result, the load when the blower 41 takes in air is reduced, so that the magnitude of the output (power consumption) of the blower 41 can also be suppressed. Further, since the output of the blower 41 is suppressed, an accessory device (for example, a radiator) for removing the operating heat of the blower 41 becomes unnecessary.

<< Configuration of controller 80 >>
Next, the configuration of the controller 80 as a control unit that detects the excrement excreted in the cup member 10, determines the type of excrement, and controls the operations of the blower 41 and the pump 63 according to the determination result will be described. do.

As shown in FIG. 7, the controller 80 includes a processor 81, a storage device 82, and an input / output interface 83 as hardware.

The processor 81 is hardware for executing the instruction set described in the program. Then, the processor 81 executes various arithmetic processes based on the programs and data stored in the storage device 82.

The storage device 82 includes, for example, a memory and a magnetic disk device, stores various programs and data, and also functions as a work memory of the processor 81. The storage device 82 may include an information storage medium such as a flash memory or an optical disk.

The input / output interface 83 communicates with devices such as an electrode unit 15, a blower 41, a pump 63, and an operation unit 34 connected via a signal transmission cable. The input / output interface 83 and each of the electrode unit 15, the blower 41, the pump 63, and the operation unit 34 may be connected by a dedicated communication cable.

The operation unit 34 is provided on the upper part of the device main body 30, includes a plurality of buttons and a display unit, and receives operations for executing and stopping various processes (washing, drying, suction, etc.) of the excrement suction device 1. ..

Specifically, current value data is input to the controller 80 from each of the first electrode pair 15a and the second electrode pair 15b of the electrode unit 15 via the input / output interface 83.
Further, the controller 80 sends a control signal of the blower 41 generated by the processor 81 to the blower 41 via the input / output interface 83 to control the operation of the blower 41.
Further, the controller 80 sends a control signal of the pump 63 generated by the processor 81 to the pump 63 via the input / output interface 83 to control the operation of the pump 63.
Further, the controller 80 receives the operation signal input to the operation unit 34 via the input / output interface 83, and executes processing according to the operation signal.

Further, the controller 80 may include a circuit for wireless communication. By doing so, the controller 80 can communicate with a computer such as a PC, a smartphone, or a tablet terminal through a wireless communication circuit. In such a case, the controller 80 may receive an operation signal from an external computer and operate the excrement suction device 1 based on the received operation signal. Further, the controller 80 may record data such as an operation log of the excrement suction device 1 and a measured value of the electrode unit 15 for each user, and transmit the recorded data to an external computer.
The wireless communication circuit may be provided in the operation unit 34 instead of the controller 80.

Further, as shown in FIG. 8, the controller 80 functions as a first determination unit 84 as a first determination means, a cleaning preprocessing unit 85 as a cleaning preprocessing means, and a second determination unit as a second determination means. The 86 and a cleaning processing unit 87 as a cleaning processing means are provided.

Each of the above-mentioned functions provided in the controller 80 is realized by the processor 81 of the controller 80 controlling each part of the controller 80 based on the program and the data stored in the storage device 82. The controller 80 may read the above program from a computer-readable information storage medium and acquire it, or may download and acquire the program via a communication network such as the Internet or an intranet.
Hereinafter, details of each of the above functions provided in the controller 80 will be described.

The first determination unit 84 is a function of determining the presence or absence of excrement in the cup member 10 based on the detection result of the electrode unit 15.
For example, the first determination unit 84 determines the cup member 10 when at least one of a plurality of electrode pairs including the first electrode pair 15a and the second electrode pair 15b of the electrode unit 15 satisfies a predetermined condition. It is determined that there is excrement on the receiving surface 11a.
Here, for the above-mentioned "detection value", for example, a current value, an impedance (resistance value), an electric conductivity, an admittance, or the like may be used. Further, the above-mentioned "predetermined condition" is a condition for detecting that the electrode pair is connected by a conductor (excrement) by a "detection value". In other words, when a conductor such as excrement is in contact with the electrode pair, the "detection value" of the electrode pair satisfies the "predetermined condition". On the other hand, when the conductor such as excrement is not in contact with the electrode pair, the "detection value" does not satisfy the "predetermined condition".
For example, when a current value is used as the above-mentioned "detection value", when the current value detected by any of the electrode pairs is equal to or higher than a predetermined value, the first determination unit 84 receives the cup member 10. It is determined that there is excrement on the surface 11a. On the other hand, when the current value detected by any of the electrode pairs is less than a predetermined value, the first determination unit 84 determines that there is no excrement on the receiving surface 11a of the cup member 10.

The first determination unit 84 is mainly realized by the processor 81 of the controller 80, the storage device 82, and the input / output interface 83 as follows.

The processor 81 of the controller 80 acquires data of the current value flowing through each electrode pair of the electrode unit 15 via the input / output interface 83. Specifically, the processor 81 acquires data of the current value flowing through each of the first electrode pair 15a and the second electrode pair 15b of the electrode unit 15 via the input / output interface 83. Then, when the positive and negative electrodes of the electrode pair are connected with the excrement as a conductor, a weak current flows.

A current also flows when the positive and negative electrodes of the electrode pair are connected using the wash water as a conductor, but since the excrement has a higher salt content (more electrolyte) than the wash water, the excrement is used as a conductor. When connected, the electrical conductivity is higher, and as a result, the current value is higher. Therefore, by comparing the current value flowing through the electrode pair with an appropriate threshold value, it is possible to distinguish whether the material in contact with the electrode pair is excrement or washing water.
Specifically, the processor 81 determines that there is excrement in the cup member 10 when the current value flowing through any of the electrode pairs is equal to or higher than a predetermined threshold value. The above-mentioned predetermined threshold value is data stored in advance in the storage device 82, and may be appropriately set based on the experimental results and the like.

Further, in the above example, a detection circuit that outputs a detection signal to the controller 80 when the current value flowing through any of the electrode pairs is equal to or higher than a predetermined threshold value may be connected to each electrode pair of the electrode unit 15. .. In this case, the processor 81 determines that the discharge has been detected in the cup member 10 when the detection signal from the detection circuit is received.

In the above example, the determination is made based on the current value detected from the electrode unit 15, but if the data changes according to the conductivity of each electrode pair of the electrode unit 15, the current value can be used. Not limited to this, other data (resistance value, electrical conductivity, etc.) may be used.

Further, the first determination unit 84 detects a change in conductivity between the positive electrode (or negative electrode) of the first electrode pair 15a and the negative electrode (or positive electrode) of any of the second electrode pairs 15b. Then, the presence or absence of excrement may be determined.
Further, the first determination unit 84 determines the change in conductivity between the positive electrode (or negative electrode) of one second electrode pair 15b and the negative electrode (or positive electrode) of the adjacent second electrode pair 15b. It may be detected to determine the presence or absence of excrement.
By doing so, it becomes possible to detect excrement in a wide range in the cup member 10.

The cleaning pretreatment unit 85 is a function of causing the suction unit 40 to perform suction when it is determined by the first determination unit 84 that the cup member 10 has excrement.
For example, when the first determination unit 84 determines that the cup member 10 has excrement, the cleaning pretreatment unit 85 causes the cleaning unit 60 to supply cleaning water to the cup member 10 together with suction by the suction unit 40. ..
Further, the cleaning pretreatment unit 85 supplies the cleaning water by the cleaning unit 60, and the output of the pump 63 is set to a mode (second output mode) having a lower output than the mode (first output mode) at the time of normal cleaning. ) May be set to operate the pump 63.

The cleaning preprocessing unit 85 is mainly realized by the processor 81 of the controller 80, the storage device 82, and the input / output interface 83 as follows.

When the processor 81 of the controller 80 determines that there is excrement in the cup member 10 by the first determination unit 84, a strong suction signal for operating the blower 41 in the strong mode is transmitted via the input / output interface 83. It is transmitted to the blower 41. Then, the blower 41 starts suction in the strong mode in response to the reception of the strong suction signal. As a result, the excrement in the cup member 10 is sucked to the excrement container 20 side through the suction hose 51.

Next, when a predetermined first time elapses from the transmission time of the strong mode operation signal, the processor 81 transmits a weak ejection signal for operating the pump 63 in the weak mode via the input / output interface 83. To transmit to. Then, the pump 63 starts the water supply from the hot water tank 62 in the weak mode in response to the reception of the weak ejection signal. As a result, the washing water is ejected from the washing water nozzle 16 toward the inside of the cup member 10 in a weak mode.
The blower 41 continues to suck in the strong mode even while the washing water is being sent from the pump 63. In this way, the washing water is ejected from the washing water nozzle 16 with a weak force, and the blower 41 sucks the washing water in the strong mode. As a result, the washing water is drawn into the excrement suction port 13, so that it is possible to prevent the unheated washing water collected in the suction hose 51 from hitting the excrement site E.

By the above treatment, the cold water accumulated in the washing water hose 52 between the hot water tank 62 and the cup member 10 can be purged (pulled out) before washing. In the following, the process of removing the cold water accumulated in the cleaning water hose 52 before cleaning by operating the blower 41 and the pump 63 in conjunction with each other is referred to as a cold water purging process.

Then, when a predetermined second time elapses after the pump 63 is operated in the weak mode, the processor 81 transmits an operation stop signal to each of the blower 41 and the pump 63 via the input / output interface 83. Then, the operation of the blower 41 and the pump 63 is stopped. The second time is set to a sufficient time, for example, to completely replace the washing water collected in the washing water hose 52.

The second determination unit 86 determines that the excrement is stool when the first determination unit 84 determines that there is excrement after the suction is executed by the cleaning pretreatment unit 85, and the first determination unit 84 determines the excrement. It is a function to determine that excrement is urine when it is determined that there is no excrement.

The reason why the second determination unit 86 determines as described above is as follows.
First, when the excrement is urine, the urine is sucked to the suction hose 51 side by the suction by the cleaning pretreatment unit 85 and the cold water purge treatment, and after the suction, the excrement is detected by the first determination unit 84. This is because it is thought that it will not be lost.
On the other hand, when the excrement is stool, the stool is heavier than the urine. This is because it is considered that the excrement is detected by the first determination unit 84 later.

The second determination unit 86 is mainly realized by the processor 81 of the controller 80, the storage device 82, and the input / output interface 83 as follows.

The processor 81 of the controller 80 acquires the current value flowing through each electrode pair of the electrode unit 15 via the input / output interface 83 after the cold water purge process is executed by the cleaning pretreatment unit 85. Then, the processor 81 determines that the excrement excreted in the cup member 10 is stool (stool) when the current value flowing through any of the electrode pairs of the electrode portions 15 is equal to or higher than a predetermined threshold value. ..
On the other hand, when the current value flowing through any of the electrode pairs of the electrode unit 15 is less than a predetermined threshold value, the processor 81 determines that the excrement excreted in the cup member 10 is urine.

The cleaning processing unit 87 is a function of operating the cleaning unit 60 in a mode according to the determination result by the second determination unit 86 to perform cleaning of the excretion site.
The cleaning processing unit 87 supplies the cleaning water by the cleaning unit 60, and the output of the pump 63 is stronger than the output mode (second output mode) in the cold water purge processing by the cleaning pretreatment unit 85 (first output). The mode) may be set to operate the pump 63.

The cleaning processing unit 87 is mainly realized by the processor 81 of the controller 80, the storage device 82, and the input / output interface 83 as follows.

When the second determination unit 86 determines that the excrement is stool (stool), the processor 81 of the controller 80 executes the cleaning process in the stool mode.
Specifically, the processor 81 performs the stool mode basic cleaning pattern C times (for example, 5 seconds) in which the blower 41 blows (suctions) for A seconds (for example, 3 seconds) and the pump 63 blows water for B seconds (for example, 5 seconds). (Times) By executing, the cleaning process in the above-mentioned stool mode is executed.
If a stop signal is input via the operation unit 34 during the execution of the cleaning process, the processor 81 may stop the cleaning process in the above-mentioned flight mode.

Further, when the second determination unit 86 determines that the excrement is urine, the processor 81 executes a cleaning process in the urine mode.
Specifically, the processor 81 performs the urine mode basic cleaning pattern F times (for example, 1) in which the blower 41 blows (sucks) for D seconds (for example, 3 seconds) and the pump 63 blows water for E seconds (for example, 3 seconds). (Times) By executing, the washing process by the above urine mode is executed.
If a stop signal is input via the operation unit 34 during the execution of the cleaning process, the processor 81 may stop the cleaning process in the urine mode.

The output of the blower 41 during the cleaning process may be, for example, equal to or higher than the output in the cold water purge. For example, if the output of the blower 41 when washing stool is A, the output of the blower 41 of B when washing urine is B, and the output of the blower 41 when executing cold water purging is C, A ≧ B ≧ C may be set. Specifically, the output of the blower 41 is in three stages of strong, medium, and weak, the output of the blower 41 during stool cleaning is strong, and the output of the blower 41 during urine cleaning is medium and cold water purge. The output of the blower 41 may be set to be weak.

Further, the output of the pump 63 during the cleaning process may be set to be stronger than the output in, for example, cold water purging. Specifically, if the output of the pump 63 is in three stages of strong, medium, and weak, and the output of the pump 63 in the cold water purge is weak, the output of the pump 63 during the cleaning process is set to, for example, medium or strong. Good as it is. Further, the output of the pump 63 may be changed between the stool mode and the urine mode. For example, the output of the pump 63 in the stool mode may be stronger than the output of the pump 63 in the urine mode.

Further, in the cleaning process in the urine mode, when the elapsed time from the previous cleaning process in the urine mode is equal to or less than the predetermined frequent urination determination time, the cleaning water is not sprayed by the pump 63 and the blower 41 blows air. Only (suction) may be performed.

<< Flow of excrement processing in excrement suction device 1 >>
Next, the flow of excrement processing by the excrement suction device 1 will be described with reference to FIGS. 9 and 10.
The process shown in FIGS. 9 and 10 is mainly executed by the controller 80 controlling each part of the excrement suction device 1.

As shown in FIG. 9, the processor 81 of the controller 80 determines whether or not excrement is detected in the cup member 10 by the electrode portion 15 (S1). For example, the process of S1 is a first determination step executed by the first determination unit 84.

If no excrement is detected in S1 (S1: No), the processing of S1 is continued.
Next, when excrement is detected in S1 (S1: Yes), the processor 81 of the controller 80 executes a cold water purge process (S2).
Here, the flow of the cold water purging process will be described with reference to the flow chart of FIG. The cold water purging treatment (pre-washing treatment step) shown in FIG. 10 may be started after a predetermined time after the excrement is detected in S1.

As shown in FIG. 10, the processor 81 of the controller 80 operates the blower 41 in the strong mode to perform suction of excrement in the cup member 10 by the blower 41 (S11).
The suction by the blower 41 continues until the end of the excrement suction process. Further, the output of the blower 41 can be changed during the suction process of excrement.

Then, the processor 81 waits until the first predetermined time elapses from the start of the suction execution by the blower 41 in S11 (S12: No), and when the first predetermined time elapses (S12: Yes), the processor 81 sets the pump 63 in the weak mode. Make it work. As a result, the washing water is ejected to the cup member 10 (S13).
The supply of the washing water to the cup member 10 by the pump 63 continues until the process of S15 described later.

Then, the processor 81 waits until a second predetermined time elapses from the start of supply of the washing water to the cup member 10 by the pump 63 in S13 (S14: No), and when the second predetermined time elapses (S14: Yes). Stops the operation of the pump 63 (S15) and finishes the cold water purging process.

Here, the process returns to FIG. 9 and the explanation is continued. As shown in FIG. 9, when the cold water purging process is completed, the processor 81 of the controller 80 again determines whether or not excrement is detected in the cup member 10 by the electrode portion 15 (S3). For example, the process of S3 is a first determination step executed by the first determination unit 84.

Then, when excrement is detected in the cup member 10 in S3 (S3: Yes), the processor 81 of the controller 80 determines that the excrement detected in S1 is stool (stool) (S4). For example, the processing of S3 and S4 is a second determination step executed by the second determination unit 86.
In this case, the processor 81 of the controller 80 executes the cleaning process in the stool mode (S5). The cleaning process in the stool mode is executed by the cleaning processing unit 87.
Further, after the cleaning treatment is executed, the ventilation treatment is appropriately executed. Specifically, the ventilation process is executed, for example, by repeating the process of operating only the blower 41 for a predetermined time while excrement is not detected in S1 (S1: No). The output of the blower 41 in this ventilation process is set to the weak mode. The ventilation process may be stopped in the middle according to the operation received by the operation unit 34, or may be stopped according to the user's setting.

On the other hand, when no excrement is detected in the cup member 10 in S3 (S3: No) and a predetermined time has elapsed from the end of the cold water purging process and the determination time has not been exceeded (S6: No). , S3 processing is continued.
Then, when no excrement is detected in the cup member 10 in S3 (S3: No) and a predetermined time has elapsed from the end of the cold water purging process and the determination time is over (S6: Yes), the controller The processor 81 of 80 determines that the excrement detected in S1 is urine (S7). For example, the processing of S3, S6, and S7 is a second determination step executed by the second determination unit 86.
In this case, the processor 81 of the controller 80 executes the washing process and the drying process in the urine mode (S8). The cleaning process in the urine mode is executed by the cleaning processing unit 87. Further, the drying treatment is executed by operating the blower 41 for a predetermined time in a state where the supply of the washing water by the pump 63 is stopped after the washing treatment is completed.
The drying time may be the same in the stool mode and the urine mode, or the drying time in the stool mode may be longer than that in the urine mode.
The above is the flow of excrement processing executed by the excrement suction device 1.

Then, according to the excrement determination method by the excrement suction device 1 and the excrement suction device 1 described above, the excrement is feces based on the detection result of the excrement by the electrode portion 15 before and after the suction of the excrement. It is possible to accurately determine whether it is urine. As a result, it is possible to suppress erroneous determination of the type of excrement and appropriately dispose of the excrement.

Further, in the excrement suction device 1, by operating the cleaning unit 60 in a mode corresponding to the type of excrement, it is possible to execute an appropriate cleaning process according to the type of excrement.

Further, in the excrement suction device 1, the cleaning water is supplied at the time of sucking the excrement, so that the excrement can be easily sucked to the excrement container 20 side. Further, the cold water accumulated in the suction hose 51 can be discharged before cleaning the excretion site.

Further, in the excrement suction device 1, in the cold water purging, the output of the pump 63 is weaker than the output at the time of normal washing, so that the cold water accumulated in the suction hose 51 of the washing water is discharged. , It is possible to prevent cold water from being applied to the excretion site.

Further, in the excrement suction device 1, the electrode unit 15 has a plurality of electrode pairs, and when the current value flowing through at least one of the plurality of electrode pairs becomes a predetermined value or more, it is said that there is excrement. judge.
By doing so, the excrement in contact with the electrode pair of the electrode portion 15 becomes a conductor, and the excrement in contact with each electrode pair can be detected. Further, by providing the cup member 10 with a plurality of electrode pairs, excrement can be detected at a plurality of places. This makes it possible to improve the detection range rate of excrement.

Further, in the excrement suction device 1, the electrode portion 15 is provided around the first electrode pair 15a provided in the center of the receiving surface 11a for receiving the excrement in the cup member 10 and the first electrode pair 15a. It has the above-mentioned second electrode pair 15b.
By doing so, the excrement can be detected at the center of the excrement receiving surface 11a and around the center of the excrement receiving surface 11a. This makes it possible to improve the detection rate of excrement regardless of the posture of the user.

<< Other Embodiments >>
In the above embodiment, the configuration of the excrement suction device of the present invention has been described with an example. However, the above embodiment is only an example, and other embodiments are also conceivable. For example, in the above embodiment, the case unit 35 as the case portion, the excrement container 20, and the blower 41 as the suction portion are housed in one housing 31. However, the present invention is not limited to this, and the excrement container 20 and the case unit 35 may be housed inside the housing 31, while the blower 41 may be provided outside the housing 31.

Further, in the above embodiment, the case where the excrement suction device of the present invention is used to suck the excrement excreted while the user is lying down has been described as an example, but the present invention is limited to this.
