FIG. 1 is a diagram showing a usage state of the excrement treatment device according to the embodiment of the present invention together with a user (human body), and shows a case where the user is lying on his back (so-called supine position). FIG. 2 is a view showing a cup included in the excrement processing apparatus, where reference numeral A is a front view, reference numeral B is a side view, and reference numeral C is a top view.
As shown in FIG. 1, the excrement treatment device 10 uses the excrement from the excrement site including the anus 11A and the urinary tract 11B of the user 11, that is, urine, feces, menstrual blood and other excrement (hereinafter, for convenience). , Urine, feces, etc., or simply referred to as excrement), which is a device that sucks and processes the cup 21, which is attached to the crotch portion 11C of the user 11, and the blower hose 22, the suction hose 23, to the cup 21. It includes a wash water hose 24 and an excrement treatment unit 100 connected via an electric wiring 25.

As shown in FIGS. 1 and 2, the cup 21 has a hollow box shape in which the anus 11A and the urethral opening 11B side of the user 11 opens, and when attached to the crotch portion 11C of the user 11, the anus 11A and the urethral opening 11A and the urethral opening. It functions as a covering member that covers the excretion site including 11B. An internal space is formed in the cup 21 including a pool portion 21T in which excrement from the anus 11A, the urethral meatus 11B, and the like is collected. The cup 21 is provided with an air outlet 31, a water injection port 32, a suction port 33, and an outside air introduction port 34 (FIG. 4, which will be described later) that communicate with the internal space.
One end of the blow hose 22 is connected to the blow port 31 via the blow hose connection port 31H provided in the cup 21, and the water injection port 32 is connected to the water injection port 32 via the wash water hose connection port 32H provided in the cup 21. One end of the washing water hose 24 is connected, and one end of the suction hose 23 is connected to the suction port 33 via a suction hose connection port 33H provided in the cup 21.

The excrement treatment unit 100 includes a control unit 101, a blower unit 102, a washing water supply unit 103, a suction unit 104, a tank unit 105, an operation unit 106, and a notification unit 107. The control unit 101 functions as a computer that controls each part of the excrement processing unit 100, and controls a suction operation for sucking the excrement in the cup 21 into the excrement processing unit 100.
This suction operation appropriately includes suction, supply of wind WD composed of air flow, and supply of wash water WT composed of warm water. The blower unit 102 includes a blower and supplies the wind WD to the blower hose 22. The wash water supply unit 103 includes a liquid pump and supplies the wash water WT to the wash water hose 24. The suction unit 104 sucks excrement (indicated by reference numeral EX in FIG. 1) through the suction hose 23 by utilizing the suction force generated by the blower of the blower unit 102. A suction source different from the blower may be provided. The tank portion 105 stores the sucked excrement, is removed at an appropriate timing, and the stored excrement is discarded at the disposal site.

The operation unit 106 inputs various instructions from the user 11 and the like, and outputs the input instructions to the control unit 101. The instructions that can be input include an instruction of an automatic operation mode in which the suction operation is automatically performed, an instruction of a manual operation mode in which the suction operation is manually performed, and the like. As a method for inputting an instruction, various known methods such as operation of a hardware switch, voice input, and communication can be applied. Under the control of the control unit 101, the notification unit 107 notifies the outside of various information using known devices such as a lamp, a display panel, and a voice device.

In the cup 21, the wind WD from the excrement processing unit 100 is supplied to the air outlet 31, and the excrement in the cup 21 is pushed out toward the suction port 33. Further, by supplying the washing water WT from the excrement treatment unit 100 to the water injection port 32, a predetermined area such as the crotch portion 11C including the anus 11A and the urethral opening 11B of the user 11 is washed. Further, the suction force of the excrement treatment unit 100 acts on the suction port 33, so that the excrement in the cup 21 is collected by the excrement treatment unit 100 via the suction port 33 and the suction hose 23. In addition to the excrement, the washing water is also collected in the excrement treatment unit 100 via the suction port 33 and the suction hose 23.

Here, the lower part in FIG. 1 is the dorsal side of the user 11, the upper part is the ventral side of the user 11, reference numeral 11L indicates the foot of the user 11, reference numeral 11P indicates the pelvis of the user 11, and reference numeral 11T indicates the pelvis of the user 11. Shows the coccyx (also called the coccyx).
The cup 21 fits between both feet 11L of the user 11 and is attached to the crotch portion 11C. When attached to the crotch portion 11C, the cup 21 extends from the dorsal side to the ventral side of the user 11 and extends from the dorsal end of the cup 21 (FIG. The position indicated by the symbol P1 in 1) terminates in front of the coccyx 11T, and the ventral end (the position indicated by the reference P2 in FIG. 1) covers and terminates the urethral meatus 11B.

Therefore, the cup 21 is made more compact than the conventional sewage treatment device provided with a flat tray that widely covers the back side of the coccyx 11T, and it becomes easy to maintain the wearing state even in a posture other than the supine position. This makes it easier for the user 11 to maintain the wearing state even in a sideways posture, turning over, a posture in which the upper body is tilted up to a predetermined angle, and a posture in which the user is in a wheelchair.
In this way, the cup 21 has been made compact so that it can be easily held in a worn state in various postures, so that a user with a high degree of care (for example, a user who needs a high degree of care) who has difficulty in movement or other movements or whose understanding level is lowered. Not only users of long-term care 4 and 5) but also users with a relatively low degree of long-term care will be able to use it easily.

Further, as shown in FIG. 1, the pool portion 21T in which excrement is collected has an angle θ1 that inclines diagonally upward toward the foot when the user 11 is lying on his back, and the pool portion 21T at this angle θ1. The depth of the cup 21 is set so that the excrement does not flow into the user 11 even if the excrement is stored in the user 11. This angle θ1 is set to an angle that makes the upper body of the user 11 substantially horizontal when the upper body of the user 11 is raised to a predetermined angle (for example, an angle within the range of 30 ° to 90 °). Therefore, even if the suction hose 23 is removed, the excrement of the pool portion 21T does not flow out from the suction port 33.

<About mounting the cup 21>
The mounting of the cup 21 will be described.
The cup 21 is attached to the user 11 by using the supporter 111.
FIG. 3 is a diagram showing the cup 21 together with the supporter 111.
The supporter 111 is made of a cloth-like material thinner than a diaper, and when worn by the user 11, has almost the same appearance as so-called shorts (shorts) having a short inseam and a length above the knee. The supporter 111 includes a supporter main body 112 having an opening 111A through which the cup 21 is passed, an abdominal pad 113 extending from the supporter main body 112 to the side covering the lower abdomen of the user 11, and the supporter main body 112 to the user 11. A pair of side portions 114 extending to the left and right sides are integrally provided. The supporter main body 112 is formed in a substantially trapezoidal shape that gradually becomes wider from the crotch portion 11C of the user 11 toward the dorsal side, and each side portion 114 extends to the left and right from the widest portion. The tip of each side portion 114 is configured to be removable from the abdominal pad portion 113 by using a hook-and-loop fastener. The peripheral edge portion 111B of the opening 111A through which the cup 21 is passed is appropriately reinforced with a reinforcing cloth or the like.

When the cup 21 is attached to the user 11, after the cup 21 is applied to the crotch portion 11C, the supporter 111 is applied to the cup 21 from the opposite side of the crotch portion 11C (corresponding to between the legs 11L) with respect to the cup 21. Each hose connection port 31H to 33H of the cup 21 is passed through the opening 111A of the supporter 111. In this case, the peripheral edge portion 111B of the opening 111A of the supporter 111 comes into contact with the back surface of the cushion 51 that covers the opening end of the cup 21, and the cup 21 is pressed against the user 11 via the cushion 51. Next, the abdominal pad 113 of the supporter 111 is applied to the lower abdomen of the user 11, the pair of left and right side portions 114 of the supporter 111 are wound around the user 11 from the left and right, and the tip of each side 114 is wrapped around the abdomen 113. By fastening, the cup 21 is attached to the user 11. The shape and material of the supporter 111 can be changed as appropriate.

<About the cup body 41 of the cup 21>
FIG. 4 is an exploded perspective view of the cup 21.
The cup 21 has an air passage WS between a concave cup body 41 that functions as a covering portion that covers the anus 11A and the urethral opening 11B, a cushion 51 that covers the open end of the cup body 41, and a bottom 41L of the cup body 41. A partition plate 61 forming (FIG. 6 to be described later) and a sensor sheet 71 laminated on the partition plate 61 are provided.
5A and 5B are views showing a cup main body 41, where reference numeral A is a front view, reference numeral B is a side sectional view, reference numeral C is a rear view, and reference numeral D is a top view.
As shown in FIGS. 4 and 5, the cup body 41 has a plate-shaped bottom that gently curves from the ventral end P1 located on the side covering the urethral meatus 11B toward the dorsal end P2 covering the anus 11A. The 41L, the wall portion 41W rising from the periphery of the bottom portion 41L, and the flange portion 41T extending along the outer peripheral edge of the wall portion 41W are integrally provided, and are formed of, for example, a resin material.

An outside air introduction port 34 and a water injection port 32 are provided in this order in the vicinity of the ventral end of the bottom portion 41L. On the back surface of the bottom portion 41L, an eaves portion 41H (see reference numeral D in FIG. 5) protruding rearward above the outside air introduction port 34, a washing water hose connection port 32H, a suction hose connection port 33H, and a blower hose connection port 31H. Are provided in order. Further, on the inner surface of the cup body 41, a plurality of protrusions 41V that function as a support for supporting the partition plate 61 are provided at intervals.

When the inside of the cup 21 becomes negative pressure due to suction or the like, the outside air is introduced into the cup 21 by the outside air introduction port 34, and the excessive negative pressure is prevented. As a result, it is possible to avoid a situation in which the cup 21 sticks too much to the human body, and it is possible to reduce the discomfort and discomfort of the user 11. Since a plurality of outside air introduction ports 34 are provided and are provided in the vicinity of the cushion 51 that comes into contact with the human body, it becomes easy to quickly adjust the pressure at the contact point between the cushion 51 and the human body to an appropriate pressure. In this configuration, the gap between the cushion 51 and the user 11 is eliminated, and the outside air can be introduced through the outside air introduction port 34, so that the inside of the cup 21 has an appropriate negative pressure during the suction operation. All hose connection ports 31H to 33H are provided on the bottom portion 41L, and the hose connection ports 31H to 33H are arranged so as to face in the same direction. This makes it easy to attach and detach the hoses 22 to 24.

The wall portion 41W is formed in a shape in which the cup 21 is gradually deepened from the ventral end to the dorsal end. Therefore, the region on the dorsal end side of the cup 21 is the deepest and has the largest volume. In this configuration, this region is the pool portion 21T. As a result, it becomes easy to secure a space for excrement and avoid contact with the user 11.

The collar portion 41T extends in an endless manner along the outer peripheral edge of the wall portion 41W, and a fixing portion 52 of the cushion 51, which will be described later, is fixed to the collar portion 41T. The flange portion 41T also functions as a reinforcing rib that reinforces the open end of the cup body 41. The cup body 41 is also formed with an opening 41G through which a wiring lead-out portion 74 (FIG. 11 described later) or the like of the sensor sheet 71, which will be described later, is passed.

<About cushion 51>
6A and 6B are views showing a cushion 51, where reference numeral A is a front view, reference numeral B is a side view, reference numeral C is a rear view, and reference numeral D is a top view.
The cushion 51 has an annular fixing portion 52 fixed to the cup body 41 and an annular elastic portion 53 corresponding to the crotch portion 11C of the user 11, and is integrated with a material having more flexibility and elasticity than the cup body 41. Is formed in. The fixing portion 52 has a groove along the inner peripheral surface of the fixing portion 52 into which the flange portion 41T of the cup body 41 is fitted, and is fixed to the cup body 41 by fitting this groove into the collar portion 41T. NS. Since the fixing portion 52 has flexibility, the work of attaching and detaching the cushion 51 becomes easy, and the cushion 51 can be easily replaced. The cushion 51 has a plate-shaped outside air guide member 54 extending toward the front of the outside air introduction port 34 provided in the cup body 41, and an outlet of the air passage WS between the bottom portion 41L of the cup body 41 and the partition plate 61. A plate-shaped wind guide member 55 extending toward the air passage outlet 62K (FIGS. 1 and 8) is further provided.

Here, FIG. 7 shows a perspective view of the cup 21 as viewed from the rear. For convenience of explanation, the portion of the supporter 111 mounted on the cup 21 including the opening 111A through which the cup 21 is passed is indicated by a chain double-dashed line. The flange portion 41T of the cup body 41 is shown by a broken line.
As described above, the supporter 111 is attached to the user 11 in a state where the opening 111A provided in the supporter main body 112 is passed through the cup 21. In this case, as shown in FIG. 7, since the peripheral edge portion 111B of the opening 111A comes into contact with the fixing portion 52 of the cushion 51, both the fixing portion 52 of the cushion 51 and the flange portion 41T of the cup body 41 are on the user 11 side. Can be pressed against. Since the flange portion 41T of the cup body 41 has a relatively rigid portion, the supporter 111 presses the entire fixed portion 52 of the cushion 51 against the user 11 with sufficient pressing pressure to eliminate the gap between the cushion 51 and the user 11. be able to. In this case, the deformation of the fixing portion 52 of the cushion 51 is suppressed by the flange portion 41T of the cup body 41, but the deformation of the elastic portion 53 of the cushion 51 is not suppressed by the flange portion 41T and is independent of the fixing portion 52 and the like. Can be transformed. Therefore, the elastic portion 53 of the cushion 51 can be deformed according to the shape of the crotch portion 11C, and the feeling of pressure on the user 11 can be easily reduced.

Further, since the gap between the cushion 51 and the user 11 can be eliminated, it becomes easy to make the inside of the cup 21 an appropriate negative pressure during the suction operation. The elastic portion 53 extends along the opening of the cup 21, and an annular cavity (see FIG. 9 described later) extending along the opening of the cup 21 is formed inside the elastic portion 53. There is. The cavity facilitates elastic deformation of the elastic portion 53, and the degree of elastic deformation of the elastic portion 53 can be adjusted by inserting another elastic member into the cavity.

<About partition plate 61>
8A and 8B are views showing a partition plate 61, where reference numeral A is a front view, reference numeral B is a side sectional view, reference numeral C is a rear view, and reference numeral D is a top view. FIG. 9 is a diagram showing the flows of the washing water WT, the wind WD, and the outside air AR in the cup 21 by arrows.
As shown in FIG. 8, the partition plate 61 has a plate-shaped partition plate main body 62 that is curved along the bottom portion 41L of the cup main body 41. The partition plate main body 62 is supported by the protrusion 41V provided on the cup main body 41, so that the air passage WS connected to the air outlet 31 between the partition plate 61 and the bottom portion 41L of the cup main body 41 (see FIG. 9). ) Is partitioned. The partition plate main body 62 is provided with an opening 62K (hereinafter, referred to as “airway outlet 62K”) that communicates with the downstream position of the air passage WS and functions as an outlet of the air passage WS, and also has a suction port 33. Is provided. The suction port 33 is located on the opposite side of the air passage outlet 62K with the excrement collecting portion 21T interposed therebetween.

The partition plate 61 is provided with a pipe portion 63 that projects from the suction port 33 toward the back surface side (corresponding to the cup body 41 side). When the partition plate main body 62 is attached to the cup main body 41, the pipe portion 63 penetrates the air passage WS and connects the suction port 33 and the suction hose connection port 33H. The suction path between the suction port 33 and the suction hose connection port 33H is partitioned from the air passage WS by the pipe portion 63, and the wind WD in the air passage WS does not directly flow into the downstream of the suction port 33.

The suction port 33 including the pipe portion 63 is provided with a plurality of blades 33A, 33B, 33C (three in this configuration) that function as crushing portions for crushing excrement passing through the suction port 33. As shown by reference numeral B in FIG. 8, these blade bodies 33A to 33C are formed in a crushing blade having a blade shape extending obliquely with respect to the axis LA of the suction port 33. These blades 33A to 33C will be further described later.

The partition plate main body 62 is provided with a pipe-shaped partition body 64 for partitioning the buffer SB (FIG. 9), which is a space having a predetermined volume, between the partition plate main body 62 and the water injection port 32 provided in the cup main body 41. Further, the partition plate main body 62 is provided with a cleaning port 65 that communicates with the buffer SB and serves as a water injection port on the downstream side, and is provided with an eaves-shaped water guide member 66 that covers the outlet of the cleaning port 65. Further, the partition plate main body 62 is also provided with an opening 62G for passing the wiring lead-out portion 74 (FIG. 11 described later) of the sensor sheet 71, which will be described later. The partition plate 61 is made of a rigid member such as a resin.

<About the flow of wind WD>
As shown in FIG. 9, the wind WD supplied to the air outlet 31 passes through the air passage WS between the partition plate 61 and the bottom 41L of the cup body 41, and the excrement collecting portion 21T from the air passage outlet 62K. Is supplied to. As shown in FIG. 9, the air passage outlet 62K is covered with a gap by the wind guide member 55 provided on the cushion 51, so that the direction of the wind WD from the air passage outlet 62K is determined by the wind guide member 55. Be changed. As shown in the figure, the wind guide member 55 covers the anus 11A and the urinary meatus 11B side of the user 11 at the air passage outlet 62K and opens to the excrement collecting portion 21T side so that the wind WD can move the wind WD to the anus 11A and the urinary meatus. The wind WD is guided to the pool portion 21T while not directly hitting the crotch portion 11C including the mouth 11B. By this wind WD, the excrement existing in the pool portion 21T can be pushed out toward the suction port 33. Since the wind guide member 55 does not directly hit the user 11, the possibility of giving the user 11 a sense of discomfort or discomfort can be reduced, and the usability can be improved.

Further, the wind guide member 55 can prevent excrement and the like from flowing into the air passage outlet 62K. In this configuration, the wind guide member 55 is integrally provided with the cushion 51 having flexibility and elasticity, and is provided at a position where the air passage outlet 62K is closed on the outlet side of the air passage outlet 62K, so that the wind WD is blown. , And functions as an opening / closing member that opens and closes the suction port 33 in response to any of suction from the suction port 33. Therefore, when the wind WD is not blown and is not sucked from the suction port 33, the air passage outlet 62K is closed and the situation where the excrement flows into the air passage outlet 62K is avoided. The wind guide member 55 may be a member independent of the cushion 51, and the design may be changed as appropriate.

Further, in this configuration, since the suction port 33 is provided on the opposite side of the air passage outlet 62K with the pool portion 21T interposed therebetween, it becomes easy to increase the flow velocity of the wind WD from the air passage outlet 62K. This also makes it easier for the excrement to be sucked into the suction port 33. In this configuration, one air outlet 31 and one suction port 33 are provided, and the suction path connecting the air port 31 to the suction port 33 has a one-pass structure, and the suction path is the partition plate 61. It is a path toward the suction port 33 along the surface of the partition plate 61 after passing through the air passage WS between the cup body and the bottom portion 41L of the cup body. As a result, the suction path can be formed at a position away from the user 11, and the excrement can be efficiently sucked while suppressing the situation where the wind WD directly hits the user 11.

<About the flow of wash water WT>
FIG. 10 is a diagram showing an XX cross section of FIG. As shown in FIG. 10, the washing water WT is supplied to a buffer SB provided between the water injection port 32 and the water guide member 66, and is discharged from the washing port 65 via the buffer SB. This buffer SB temporarily stores the washing water WT so that cold water (residual water of the washing water hose 24, etc.) immediately after supply is not immediately discharged from the washing port 65, and is mixed with hot water for washing. Water WT can be discharged from the cleaning port 65. That is, this buffer SB suppresses the temperature change of the washing water WT, and makes it easier to supply the washing water WT at an appropriate temperature.

The drainage direction of the wash water WT discharged from the wash port 65 is changed by the water guide member 66. As shown in FIGS. 9 and 10, in the water guide member 66 of the present configuration, the wash water WT flows from the urinary tract opening 11B to the anus 11A, and the wash water WT after washing flows into the excrement pool 21T. Guide the wash water WT in the direction to go. As a result, the washing water WT is sucked into the suction port 33 via the excrement collecting portion 21T after washing the excrement site including the anus 11A and the urethral opening 11B.
Since the washing water WT is guided by the water guiding member 66, only the part to be washed by the user 11 can be washed. Moreover, since the washing water WT is sucked into the suction port 33 by the water guide member 66 via the excrement collecting portion 21T, the washing water WT makes it easier to float the excrement and makes it easier to suck the excrement.

<About the flow of outside air AR>
As shown in FIG. 10, the flow direction of the outside air AR introduced into the outside air introduction port 34 is changed by the outside air guiding member 54. In this configuration, the outside air AR guides in a direction avoiding the crotch portion 111C. As a result, it is possible to avoid a situation in which the inside of the cup 21 becomes excessively negative pressure due to the introduction of outside air, avoid a situation in which the outside air AR directly hits the user 11, and suppress a situation in which the user 11 feels discomfort or discomfort due to the outside air AR. .. Further, the outside air guiding member 54 can prevent the moisture in the cup 21 from jumping out through the outside air introduction port 34.

In this configuration, the outside air guide member 54 is integrally provided with the cushion 51 having flexibility and elasticity, and is provided at a position where the outside air introduction port 34 is closed on the outlet side of the outside air introduction port 34, so that the inside of the cup 21 is provided. It functions as an opening / closing member that opens / closes the outside air introduction port 34 according to the negative pressure of. Therefore, when the pressure inside the cup 21 is not excessively negative, it is possible to sufficiently prevent the moisture in the cup 21 from jumping out through the outside air introduction port 34. The outside air guide member 54 may be a member independent of the cushion 51, and the design may be changed as appropriate.

<About the sensor sheet 71>
Next, the sensor sheet 71 will be described.
FIG. 11 is a diagram showing a sensor sheet 71.
The sensor sheet 71 is formed of a flexible sheet, and pulls out the first circuit pattern 72 that can detect moisture, the second circuit pattern 73 that can detect moisture, and the wiring connected to each of the circuit patterns 72 and 73. It is provided with a wiring lead-out portion 74. The first circuit pattern 72 and the second circuit pattern 73 are arranged at positions separated from each other, and a through hole 75 having the same size as the suction port 33 of the partition plate 61 is formed between the circuit patterns 72 and 73. ing.

The first circuit pattern 72 includes a plurality of continuity detection terminals 72A to 72J, and the resistance value between the terminals of the continuity detection terminals 72A to 72J becomes low when the terminals are electrically connected to each other via moisture. It is used to detect the presence or absence of moisture from the resistance value between each terminal. That is, the first circuit pattern 72 functions as a first detection unit that detects excrement containing water.
The second circuit pattern 73 includes a plurality of continuity detection terminals 73A to 73F, and the resistance value between the terminals of the continuity detection terminals 72A to 72J becomes low when the terminals are conducted through moisture. It is used to detect the presence or absence of moisture from the resistance value between each terminal. That is, the second circuit pattern 73 functions as a second detection unit that detects excrement containing water. Hereinafter, for convenience of explanation, the first circuit pattern 72 will be referred to as a “first detection unit”, and the second circuit pattern 73 will be referred to as a “second detection unit 73”.

The sensor sheet 71 is fixed to the surface of the partition plate 61 so that the through hole 75 and the suction port 33 overlap each other, so that the second circuit pattern 73 is formed in the excrement collecting portion 21T as shown in FIG. The first detection unit 72 is arranged in the region, and the first detection unit 72 is arranged in the region above the pool portion 21T. In other words, the second detection unit 73 is arranged in a region where excrement from the anus 11A is relatively easy to detect, and the first detection unit 72 is relatively easy to detect excrement from the urethral opening 11B side. Moreover, it is arranged in an area where excrement from the anus 11A is relatively difficult to detect.
The wiring lead-out portion 74 is pulled out to the back surface of the cup main body 41 through the openings 62G and 41G of the partition plate main body 62 and the cup main body 41, and is electrically connected to the excrement treatment unit 100 via the electric wiring 25. .. A known connector structure can be widely applied to the connection between the wiring lead-out portion 74 and the electrical wiring 25. By fixing the sensor sheet 71 and the partition plate 61, the partition plate 61 functions as a sensor plate on which a sensor for detecting excrement is arranged. By directly providing the continuity detection terminals 73A to 73F and 73A to 73F on the partition plate 61, the sensor plate may be formed by the partition plate 61 alone. The terminal arrangement of the first detection unit 72 and the second detection unit 73 is not limited to the arrangement shown in FIG. 11, and can be changed as appropriate.

<About operation in automatic operation mode>
FIG. 12 is a flowchart showing the operation at the start of the automatic operation mode.
The control unit 101 of the excrement processing unit 100 monitors whether or not water has been excreted by determining whether or not water has been detected by either the first detection unit 72 or the second detection unit 73 (step S1). : Excretion monitoring). The control unit 101 says that when the resistance value between the terminals of the conduction detection terminals 72A to 72J of the first detection unit 72 in a predetermined combination falls within a predetermined range, the first detection unit 72 detects moisture. judge. Further, the control unit 101 detects moisture in the second detection unit 73 when the resistance value between the terminals of the conduction detection terminals 73A to 73F of the second detection unit 73 in a predetermined combination falls within a predetermined range. Judged as

If no water is detected (step S1: NO), the control unit 101 proceeds to step S9 and continues excretion monitoring. On the other hand, when water content is detected (step S1: YES), the control unit 101 makes a primary determination to specify whether or not the first detection unit 72 or the second detection unit 73 first detects water content. , The determination result is stored in a memory (not shown) (step S2). When the water content is detected, the control unit 101 immediately starts the suction operation (step S3).
As a suction operation, the control unit 101 first operates the blower of the blower unit 102, supplies the wind WD by the blower unit 102, and starts suctioning the excrement and the like in the cup 21 by the suction unit 104.

After starting the suction operation, the control unit 101 determines whether or not the predetermined time T1 has elapsed, and if it determines that the predetermined time T1 has elapsed, whether or not the second detection unit 73 has detected water. A secondary determination is performed to specify whether or not, and the determination result is stored in a memory (not shown) (step S4).
Here, the predetermined time T1 is set to a time during which the flow of the wind WD from the air outlet 31 to the suction port 33 becomes steady, and is set to, for example, 5 seconds. When the wind WD becomes steady, liquid excrement from the urethral opening 11B or the like is quickly sucked into the suction port 33.

When the result of the secondary determination is obtained, the control unit 101 sets the suction mode to the first suction mode suitable for a liquid such as urine, or a solid such as stool, based on the combination of the primary determination and the secondary determination. It is determined whether or not to set the second suction mode suitable for sucking an object (step S5).
The first suction mode is a mode that saves more energy than the second suction mode. As an example, the first suction mode is a mode in which washing water is supplied for 4 seconds and the blower is stopped after 10 seconds, and the second suction mode is an operation mode in which the same operation as the first suction mode is repeated a plurality of times. be. In this second suction mode, the washing water is intermittently supplied, so that the pressure in the cup 21 fluctuates, and the fixed stool is vibrated to facilitate suction.

FIG. 13 shows the first table data TD1 used for the mode determination in step S3. By referring to the first table data TD1, the control unit 101 determines which of the patterns P1, P2, P3, and P4 shown in FIG. 13 corresponds to the combination of the primary determination and the secondary determination, and the control unit 101 determines which of the patterns P1, P2, P3, and P4 shown in FIG. Execute the suction mode corresponding to the pattern.
According to the first table data TD1, in the primary determination, the first detection unit 72 first detects the water content (first detection unit: ON), and in the secondary determination, the second detection unit 73 does not detect the water content. (Second detection unit: OFF), corresponds to pattern P1, and is determined to be the first suction mode. Further, in the primary determination, when the first detection unit 72 first detects moisture (first detection unit: ON), and in the secondary determination, when the second detection unit 73 detects moisture (second detection unit: ON). ), Corresponds to the pattern P2, and is determined to be the first suction mode.

Further, in the primary determination, the second detection unit 73 first detects the moisture (second detection unit: ON), and in the secondary determination, the second detection unit 73 does not detect the moisture (second detection unit: OFF). ), Corresponds to the pattern P3, and is determined to be the first suction mode. Further, in the primary determination, when the second detection unit 72 first detects moisture (second detection unit: ON), and in the secondary determination, when the second detection unit 73 detects moisture (second detection unit: ON). ), Corresponds to the pattern P4, and is determined to be the second suction mode.

When the excrement is a solid substance such as stool, there is a high possibility that the second detection unit 73 first detects water in the primary determination, and the second detection unit 73 also detects water in the secondary determination. That is, it becomes easy to accurately identify whether the excrement is a fixed excrement from the anus 11A or a liquid excrement other than the anus 11A, depending on whether or not the pattern is P4.
If the type of excrement is to be specified only by the primary determination, if the first detection unit 72 detects water first, it is determined to be the first suction mode, and the second detection unit 73 detects water first. In this case, a method of determining the second suction mode can be considered.
However, in the case of this method, due to various factors such as the posture change of the user 11, the position where the urine from the urethral meatus 11B is detected by the second detection unit 73 is not the position where the urine is detected by the first detection unit 72. If it flows to, it will be determined as the second suction mode. Therefore, although the first suction mode is sufficient, the second suction mode, which consumes a lot of energy, is executed.

In this configuration, even if the second detection unit 72 first detects water, if the second detection unit 73 does not detect water in the secondary determination (corresponding to pattern P3), it is determined to be the first suction mode. Therefore, even when the urine from the urethral meatus 11B flows to the position detected by the second detection unit 73 due to various factors, the suction mode according to the type of excrement can be specified. Further, even if the excrement is from the anus 11A, even if it is a small amount or liquid excrement that is immediately sucked, it is determined as the first suction mode as the pattern P3. As a result, it is possible to avoid the situation where the second suction mode, which consumes a lot of energy, is executed even though the first suction mode is sufficient.

Returning to FIG. 12, when the control unit 101 determines that it is in the first suction mode, it shifts to step S6 and performs the suction operation in the first suction mode, while when it determines that it is in the second suction mode, it shifts to step S7. , The suction operation is performed in the second suction mode. As a result, the suction operation can be performed according to the type of excrement.
After the suction operation is completed, the control unit 101 determines that water is not detected by either the first detection unit 72 or the second detection unit 73 during the predetermined standby time T2 (step S8: YES), step S9. And monitor excretion. On the other hand, when the water content is detected by either the first detection unit 72 or the second detection unit 73 during the standby time T2 (step S8: NO), the control unit 101 proceeds to step S10. Perform continuous processing. The standby time T2 may be set to an arbitrary time, for example, 2 minutes.

FIG. 14 is a flowchart showing the operation of continuous processing.
The control unit 101 makes a primary determination to specify whether or not the first detection unit 72 or the second detection unit 73 first detects water after the previous suction operation (step S1A), and also performs the suction operation. Start (step S2A). Next, when the control unit 101 determines that a predetermined time T3 has elapsed from the start of the suction operation, the control unit 101 makes a secondary determination to specify whether or not the second detection unit 73 has detected moisture (the second detection unit 73). Step S3A). The predetermined time T3 is set to a time during which the flow of the wind WD from the air outlet 31 to the suction port 33 becomes steady, and is set to, for example, the same time as the predetermined time T1.

Next, when the previous suction mode is the second suction mode (step S4A: second suction mode), the control unit 101 specifies the suction mode based on the table data TD1 and identifies the suction mode, as in step S5. Perform suction operation with.
On the other hand, when the previous suction mode is the first suction mode (step S4A: first suction mode), the control unit 101 determines the frequency of urination in step S5A.

FIG. 15 shows the second table data TD2 used for determining pollakiuria. By referring to the second table data TD2, the control unit 101 determines which of the patterns P5, P6, P7, and P8 shown in FIG. 15 corresponds to the combination of the primary determination and the secondary determination, and determines which of the patterns P5, P6, P7, and P8 shown in FIG. Execute the suction mode corresponding to the pattern. In the second table data TD2, a third suction mode suitable for frequent urination is appropriately specified. This third suction mode is an operation mode in which a small amount of liquid is sucked, for example, only a blower for 10 seconds.

According to the second table data TD2, in the primary determination, the first detection unit 72 first detects the moisture (first detection unit: ON), and in the secondary determination, the second detection unit 73 does not detect the moisture. (Second detection unit: OFF), corresponds to pattern P5, and is determined to be the third suction mode. Further, in the primary determination, when the first detection unit 72 first detects moisture (first detection unit: ON), and in the secondary determination, when the second detection unit 73 detects moisture (second detection unit: ON). ), Corresponds to pattern P6, and is determined to be the third suction mode. Further, in the primary determination, the second detection unit 73 first detects the moisture (second detection unit: ON), and in the secondary determination, the second detection unit 73 does not detect the moisture (second detection unit: OFF). ), Corresponds to the pattern P7, and is determined to be the third suction mode. Further, in the primary determination, when the second detection unit 72 first detects moisture (second detection unit: ON), and in the secondary determination, when the second detection unit 73 detects moisture (second detection unit: ON). ), Corresponds to the pattern P8, and is determined to be the second suction mode.

As described above, in the primary determination, the second detection unit 73 first detects the water content, and in the secondary determination as well, only when the second detection unit 73 detects the water content, it is specified as the second suction mode that consumes a lot of energy. Other than that, it is specified as the third suction mode, which consumes less energy. As a result, in the case of frequent urination, it can be determined that the third suction mode is used.
Returning to FIG. 14, when the control unit 101 determines that it is in the third suction mode, it shifts to step S6A and performs the suction operation in the third suction mode, while when it determines that it is in the second suction mode, it shifts to step S7A. , The suction operation is performed in the second suction mode. As a result, it is possible to operate in an appropriate suction mode depending on whether or not frequent urination occurs, and it becomes easier to save energy.

After the suction operation is completed, the control unit 101 determines that water is not detected by either the first detection unit 72 or the second detection unit 73 during the predetermined standby time T4 (step S8A: YES), step S9. And monitor excretion. On the other hand, when the water content is detected by either the first detection unit 72 or the second detection unit 73 during the standby time T4 (step S8A: NO), the control unit 101 proceeds to step S10. Perform continuous processing again. The standby time T4 may be set to an arbitrary time, and is set to, for example, the same time as the standby time T2.

<About the crushed part>
Next, a plurality of blades 33A to 33C that function as crushing portions provided in the suction port 33 will be described. Hereinafter, when a plurality of blades 33A to 33C are described separately, they are referred to as the first blade 33A, the second blade 33B, and the third blade 33C.
As shown in FIG. 8, these blades 33A to 33C are arranged at equal angular intervals in the circumferential direction of the suction port 33, and are arranged from the inner peripheral surface of the suction port 33 (including the inner peripheral surface of the pipe portion 63). It is formed in a blade shape that protrudes toward the center of the suction port 33.
Reference numeral A in FIG. 16 is a diagram showing the first blade 33A together with the peripheral configuration, reference numeral B is a diagram showing the second blade 33B together with the peripheral configuration, and reference numeral C is a diagram showing the third blade 33C together with the peripheral configuration. It is a figure.

All of these blades 33A to 33C extend obliquely with respect to the axis LA of the suction port 33. More specifically, the first blade 33A and the second blade 33B, as shown by reference numerals A and B in FIG. 16, direct the excrement flowing into the suction port 33 toward the downstream side in the right-handed screw direction. It is formed in a blade shape that inclines in the direction of rotation.
On the other hand, as shown by the reference numeral C in FIG. 16, the third blade 33C is formed in a blade shape in which the excrement flowing into the suction port 33 is inclined in the direction of rotating the excrement in the left-handed screw direction toward the downstream side. Has been done. That is, the third blade 33C extends in the opposite direction of the first blade 33A and the second blade 33B with respect to the axis LA of the suction port 33.

According to this configuration, the excrement flowing into the suction port 33 can be rotated in the right-handed direction by the first blade 33A and the second blade 33B, and the excrement can be cut by the third blade 33C. can. As a result, the excrement can be threaded and the excrement can be crushed. Since the excrement can be crushed, a large stool can be crushed and easily flowed to the suction hose 23. In other words, even if the suction path connected to the suction port 33 is narrowed, the excrement is less likely to be clogged and the adhesion of the excrement can be suppressed. Further, by narrowing the suction path, the suction speed can be increased, and the cleaning effect of the suction hose 23 with the cleaning water WT can be expected. As a result, clogging of the suction path and adhesion of excrement can be suppressed, and cleaning of the suction hose 23 and the like can be facilitated.

Further, since the blades 33A to 33C can generate a vortex in the water flow of the cleaning water WT, the effect of cleaning the inner peripheral surface of the suction port 33 and the suction hose 23, that is, the effect of removing dirt can be expected. The number, shape, and position of the blades 33A to 33C may be changed as appropriate, and the configuration of each part is not limited to the above configuration.

For example, as shown in FIG. 17, a sub-spout 33G for discharging air flow or water may be provided on the inner peripheral surface of the suction port 33 (including the inner peripheral surface of the pipe portion 63). The sub-outlet 33G functions as another crushing unit that crushes the excrement passing through the suction port 33 by the discharged air flow or water. In the example shown in FIG. 17, since the sub-outlet 33G is provided at a position corresponding to the blades 33A to 33C, when excrement is caught in any of the blades 33A to 33C, the sub-outlet 33G is discharged. It is possible to eliminate the catching, and this also suppresses the clogging. The number, shape and position of the sub-outlet 33G may be changed as appropriate.

<Effects related to wind flow>
As described above, as shown in FIG. 9, the excrement treatment device 10 of the present embodiment includes a cup 21 that covers the excrement portion including the anus 11A and the urinary tract opening 11B, and the cup 21 is the bottom of the cup 21. The partition plate 61 that forms the air passage WS in 41L, the air outlet 31, and the suction port 33 are provided, and the wind WD supplied to the air passage 31 passes through the air passage WS and passes through the excrement collecting portion 21T. It is configured to go to the suction port 33 via the structure. According to this configuration, it is possible to make it difficult for the wind WD to hit the excretion site including the anus 11A and the urethral meatus 11B, and the user 11 is less likely to feel discomfort or discomfort during suction. Therefore, the usability can be improved, and it becomes easy for various users including the user 11 who has a relatively low degree of care to use it.

In this case, the partition plate 61 communicates with the air outlet 31 as an air passage WS, partitions a space passing through the crotch portion 11C of the user 11 in the excrement collecting portion 21T, and is located at the downstream end of the air passage WS. An air passage outlet 62K communicating with the excrement collecting portion 21T is provided. Thereby, with a simple configuration, it is possible to form a wind channel WS in which it is difficult to apply the wind WD to the excretion site including the anus 11A and the urethral meatus 11B.

Further, a pool portion 21T is provided on the surface of the partition plate 61 exposed to the crotch portion 11C side of the user 11, and the partition plate 61 and the sensor sheet 71 form a sensor plate, so that the excrement of the pool portion 21T can be collected. It becomes easier to detect. Further, by directly providing the continuity detection terminals 73A to 73F and 73A to 73F of the sensor sheet 71 on the partition plate 61, the partition plate 61 itself can be used as a sensor plate, which is advantageous in reducing the number of parts.

Further, since the suction port 33 has a pipe portion 63 that penetrates the air passage WS toward the pool portion 21T, the suction port 33 can be provided at a position where the excrement of the pool portion 21T can be easily sucked. Further, the position of the suction path on the downstream side including the suction port 33 can be set without being restricted by the air passage WS.
Further, since the wind guide member 55 for guiding the wind WD in the direction avoiding the predetermined region (corresponding to the crotch portion 11C) including the excretion point of the user 11 is provided at the outlet of the wind passage WS, the wind WD is also provided by this. Is less likely to hit the user 11 directly, which contributes to the improvement of usability.

Further, since the wind guide member 55 is provided on the opposite side of the suction port 33 with respect to the excrement pool portion 21T, the direction of the wind WD toward the pool portion 21T can be adjusted by the wind guide member 55. It becomes easier to suck excrement.
Further, since the outside air guiding member 54 for guiding the outside air in the direction avoiding the predetermined area (corresponding to the crotch portion 11C) including the excretion point of the user 11 is provided at the outlet of the outside air introduction port 34 provided in the cup 21. It is possible to avoid a situation in which the inside of the cup 21 becomes excessively negative pressure, and it becomes difficult for the outside air to directly hit the user 11, which contributes to the improvement of usability.

Moreover, the cup 21 of the present embodiment extends from the dorsal side to the ventral side when attached to a portion covering the excretion portion of the user 11, and the dorsal end portion (position indicated by reference numeral P1 in FIG. 1) is a coccyx 11T. Since the end is terminated in front and the ventral end (position indicated by reference numeral P2 in FIG. 1) covers the urinary meatus 11B and terminates, the cup 21 can be made compact and it is easy to hold the wearing state even in a posture other than the supine position. Become.

<Effects related to the flow of wash water WT>
In the present embodiment, as shown in FIG. 9, the washing water WT supplied to the water injection port 32 provided in the cup body 41 has an excretion point (corresponding to the crotch portion 11C) including the anus 11A and the urethral opening 11B. After washing, the excrement is sucked into the suction port 33 via the excrement pool 21T, so that the excrement portion can be sufficiently washed, and the excrement can be floated by the washing water WT to easily suck the excrement. ..

Further, since the washing water WT has a water guide member 66 that cleans the excretion portion of the user 11 and guides the washed water WT in the direction toward the pool portion 21T, the water guide member 66 provides a cleaning effect and excretion. It becomes easy to improve the suction effect of an object.
Moreover, since the buffer SB that suppresses the temperature change of the washing water WT is provided between the water injection port 32 and the water guide member 66, the temperature change of the washing water WT is suppressed and the washing water WT at an appropriate temperature is supplied. It becomes easy to make it. Further, since the washing water is intermittently supplied, the pressure in the cup 21 is fluctuated, and the fixed stool is vibrated to facilitate suction.

<Action and effect related to the shape of the cup 21>
As shown in FIG. 1, the cup 21 of the present embodiment has a thick dorsal end (position indicated by reference numeral P1 in FIG. 1) and is directed toward the ventral end (position indicated by reference numeral P2 in FIG. 1). Therefore, it becomes easy to secure a space for excrement to collect and avoid a situation where the excrement comes into contact with the user 11.
Moreover, the pool portion 21T for collecting excrement is in a substantially horizontal state when the upper body of the user 11 to which the cup 21 is attached is raised to a predetermined angle. It becomes difficult for excrement to flow to the opposite side of the user 11 in the range. As a result, even if the suction hose 23 is removed, the excrement is less likely to flow out to the outside.

<Action and effect of crushed part>
Since the suction port 33 of the cup 21 of the present embodiment is provided with blades 33A, 33B and 33C that function as crushing portions for crushing the excrement passing through the suction port 33, the suction path is clogged and the excrement adheres. It is possible to facilitate cleaning of the suction hose 23 and the like. Since clogging of the suction path can be suppressed, the suction path can be narrowed to increase the suction speed, and thereby the effect of automatically cleaning the suction hose 23 with the suction water WT can be expected.

Further, the blades 33A, 33B and 33C include blades 33A and 33B for rotating excrement in a predetermined direction toward the downstream side, and other blades 33A and 33B for rotating excrement in a direction opposite to the predetermined direction toward the downstream side. Since it has a blade 33C, it is possible to rotate the excrement with any of the blades 33A, 33B and 33C, and make a cut in the excrement with the other blade to thread the excrement, and efficiently crush the excrement. can.
In this case, the blades 33A and 33B are blades extending in a direction diagonally intersecting the axis LA of the suction port 33, and the other blades 33C are the blades 33A and 33A with respect to the axis LA of the suction port 33. By using a blade that extends in the opposite direction of 33B, it is possible to realize a blade that rotates the excrement as described above.

Further, since these blades 33A, 33B and 33C are provided at intervals in the circumferential direction of the suction port 33, relatively large excrement can be collected from a plurality of blades 33A, 33B and 33C among these blades 33A, 33B and 33C. At the same time, it becomes easy to crush. Further, by providing the sub-outlet 33G that functions as another crushing portion, clogging of the suction path or the like can be suppressed, and the suction path can be narrowed to facilitate the speeding up of the suction speed.

<Actions and effects of the first detection unit 72 and the second detection unit 73>
The cup 21 can detect excrement from the anus 11A, the urethral meatus 11B, etc. as a sensor for detecting excrement, and the first detection unit 72 and the second detection unit 73 are arranged at positions separated from each other. And are provided. Then, when any of the first detection unit 72 and the second detection unit 73 detects the excrement, the control unit 101 of the excrement processing unit 100 starts a suction operation, and then the first detection unit 72 and the second detection unit 72. Of the two detection units 73, the second detection unit 73, which is arranged at a position where the excrement of the anal 11A is relatively easy to detect, performs a post-suction determination process for determining whether or not the excrement is detected. When it is determined in the determination process that excrement is not detected by the second detection unit 73, the suction operation is performed in the first suction mode, and when it is determined that the excrement is detected by the second detection unit 73, the first suction mode is performed. The suction operation is performed in the second suction mode, which consumes more energy than. Thereby, the suction mode according to the type of excrement can be specified.

On the other hand, conventionally, for excrement detected by a sensor for detecting moisture, the presence or absence of odor detected by a sensor for detecting odor is used to perform a suction operation according to the type of excrement. be. In the present embodiment, it is possible to perform a suction operation according to the type of excrement without using a sensor for detecting moisture and a sensor for detecting odor. As a result, it is possible to suppress the situation of operating in the second suction mode, which consumes a lot of energy unnecessarily, and to save energy.

In addition, the control unit 101 makes a primary determination in which the detection unit that first detects excrement determines either the first detection unit 72 or the second detection unit 73, and the second detection unit 73 excretes in the primary determination. When an object is detected and the second detection unit 73 detects excrement in the secondary determination consisting of the determination process after suction, the suction operation is performed in the second suction mode, and the first detection unit 72 in the primary determination. Alternatively, if the second detection unit 73 detects the excrement and the second detection unit 73 does not detect the excrement in the secondary determination, the suction operation is performed in the first suction mode. As a result, if the second detection unit 73 detects excrement in the primary determination but the second detection unit 73 does not detect excrement in the secondary determination, it may be urine or the first suction mode. It can be regarded as inhalable excrement and energy saving can be achieved.

Since the first detection unit 72 and the second detection unit 73 detect moisture, it is advantageous in cost reduction as compared with the case of using other sensors capable of detecting excrement such as an odor sensor, and one type of sensor. Therefore, the suction operation according to the type of excrement becomes possible. The first detection unit 72 and the second detection unit 73 may detect excrement other than the configuration for detecting water content.

Further, as shown in FIG. 9, the first detection unit 72 is arranged at a position where the excrement of the urethral meatus 11B is relatively easy to detect, and the second detection unit 73 is the excrement of the anus 11A and the urethral meatus 11B. Is placed in a position where it can be detected. As a result, excrement can be detected even when the urine from the urethral meatus 11B flows to the position detected by the second detection unit 73 instead of the position detected by the first detection unit 72, and the excrement is adjusted to the urine. It becomes easier to perform suction operation.
Further, since the second detection unit 73 detects the excrement in the excrement collecting part 21T, the excrement can be reliably detected and the suction operation can be performed.

<Effects related to mounting the cup 21>
As shown in FIG. 5, the cushion 51 provided on the cup 21 has a fixing portion 52 to the cup 21 and an elastic portion 53 corresponding to the crotch portion 11C of the user 11, and the supporter 111 that attaches the cup 21 to the user 11. Has an opening 111A through which the cup 21 passes. Then, as shown in FIG. 7, the peripheral edge portion 111B of the opening 111A is brought into contact with the fixed portion 52 of the cushion 51, and the cup 21 is attached to the user 11 by the supporter 111. According to this configuration, since the elastic portion 53 of the cushion 51 is displaced independently, the feeling of pressure on the user 11 is eliminated and pain or the like does not occur. Further, since the peripheral edge portion 111B of the opening 111A of the supporter 111 is brought into contact with the fixing portion 52 of the cushion 51, it becomes easier for the user to properly hold the cup, and the opening 111A of the supporter 111 and the fixing portion 52 of the cushion 51 are brought into contact with each other. Leakage from between can be prevented.

Further, the cup 21 has a hollow box shape in which the excretion site side including the anus 11A and the urethral meatus 11B opens, has a collar portion 41T extending along the outer peripheral edge of the opening, and the fixing portion 52 of the cushion 51 has a fixed portion 52. It is formed in a shape that grips the flange portion 41T and covers the entire circumference of the opening. According to this configuration, the fixing force of the cup 21 by the supporter 111 can be increased by utilizing the rigidity of the collar portion 41T.
Further, since the elastic portion 53 of the cushion 51 has an annular cavity extending along the opening of the cup 21, the elastic portion 53 is easily elastically deformed and another elastic member is inserted into the cavity. The degree of elastic deformation can be adjusted.

It should be noted that the above-described embodiment is merely an example of one aspect of the present invention, and can be arbitrarily modified and applied without departing from the gist of the present invention.
For example, the case where the present invention is applied to the excrement treatment device 10 and the cup 21 shown in FIG. 1 has been described, but the structure and shape of each part may be appropriately changed. Further, the outside air may be blown into the cup 21. In this case, an outside air adjusting device that performs at least one of deodorization, dust removal, humidity adjustment, and the like may be provided, and the outside air that has passed through the outside air adjusting device may be supplied into the cup 21.
