For this reason, a large amount of air Y flows into the upper region of the tube cross section of the hose 1073, so that a vacuum state cannot be formed, and there is a possibility that the urination feces and the washing water Z cannot be sucked smoothly from the start end to the end of the hose 1073. .

  As a result, there is a risk that urine and washing water adhere to and accumulate on the discharge passage 1081 or the inner wall of the hose 1073 of the urine / feces processing body 1051 and cause odor.

  An object of the present invention is to provide an automatic urinary stool processing apparatus that can quickly store urinary stool and washing water in a stool storage part without accumulating in the urinary stool processing body and the hose.

According to the first aspect of the present invention, a mounting hole is formed in the center of the bed for bedding and a pipe passage is formed from the mounting hole to the end of the bedding bed. In the automatic urine processing apparatus configured to communicate with the fitted discharge pipe and to convey the urine feces to the outside of the bedding bed through the discharge pipe by the urine stool processing body, from the inside of the urine stool processing body to the end of the discharge pipe A bent portion is formed in a part of the urination stool passage leading to generate a vortex when the urine is transported , and the bent portion is formed by injecting air into the air bag .

  According to a second aspect of the present invention, in the automatic urination / feces processing apparatus according to the first aspect, the bent portion is formed in a urination / feces receiving portion of a processing unit main body in the urination / feces processing body.

  According to a third aspect of the present invention, in the automatic urination / feces processing apparatus according to the first aspect, the bent portion is formed in the middle of the discharge pipe.

  According to a fourth aspect of the present invention, in the automatic urination / feces processing apparatus according to the first aspect, the bent portion is formed in the vicinity of the starting end of the discharge pipe.

  According to a fifth aspect of the present invention, in the automatic urination / feces processing apparatus according to the first aspect, the bent portion is formed near the end of the discharge pipe.

  A sixth aspect of the present invention is the automatic urination / feces processing apparatus according to any one of the first to fifth aspects, wherein the bent portion bends the urine passageway upward.

  A seventh aspect of the present invention is the automatic urination processing apparatus according to any one of the first to fifth aspects, characterized in that the bent portion bends the urinary stool passage downward.

According to the first aspect of the present invention, when a bent portion formed by injecting air into the air bag is formed in a part of the urination passage from the inside of the automatic urination processing apparatus to the end of the discharge pipe, When the urination feces and washing water discharged into the treatment body are transported out of the bedding bed through the discharge pipe, the urination feces and washing water are blocked at the bent portion of the urination stool passage, so that the space of the urination toilet passage is increased. When suction is performed in this state, the inside of the urinary stool passage on the lower side of the dammed portion becomes a negative pressure state, and when the urine and washing water flow through the bent portion of the urination stool passage In the urinary stool and wash water at the center of the cross section of the urine passage, centrifugal force is generated by the curvature of the bent portion, and a first flow from the lower portion of the bent portion to the upper portion (or from the upper portion to the lower portion) is generated. Also, the bent part of the urination passage Since the pressure distribution is different between the upper part and the lower part, a pressure gradient force acts to generate a second flow from the upper part to the lower part (or from the lower part to the upper part) of the bent part. An eddy current will be generated. The urination feces and washing water accompanied by the vortex can be quickly discharged out of the urination passage. Further, urination feces and washing water do not adhere and accumulate in the urination passage, and it is possible to prevent odor generated from the urination passage and always use it cleanly.

  According to the second aspect of the present invention, since the bent portion is formed in the urination stool receiving portion of the processing unit main body in the urination and stool processing body, when the urination stool and the washing water are discharged into the urination and stool processing body, In this state, the space of the urine receiving part is sealed or narrowed by damming the urine and washing water, and if suction is performed in this state, the inside of the urine receiving part on the lower side of the bent part becomes a negative pressure state, In addition, the wash water is quickly transported out of the urine processing body. Furthermore, when urine and washing water flow through the bent portion of the urine receiving part, centrifugal force is generated in the urine and washing water at the central position in the tube cross section of the urine receiving part due to the curvature of the bent part. A first flow is generated from the lower part of the bent part to the upper part (or from the upper part to the lower part), and the pressure distribution force acts on the upper and lower parts of the bent part in the urination and stool receiving portion. Then, a second flow is generated from the upper part to the lower part (or from the lower part to the upper part) of the bent part, and eddy currents are generated by the first flow and the second flow. The urination feces and washing water accompanied by the vortex flow can be quickly discharged out of the urination toilet body. At this time, since the urinary stool and the wash water are sucked out with a strong suction action, there is an effect that the urine stool and the wash water do not adhere and accumulate in the urine stool processing body.

  According to the third aspect of the present invention, since the bent portion is formed in the middle of the discharge pipe, the space in the cross section of the discharge pipe is sealed or sealed by blocking the medium volume of urine feces and washing water at the bent portion. When the suction is performed in this state, the inside of the discharge pipe on the lower side of the bent portion is in a negative pressure state, and the urine feces and the washing water are quickly conveyed toward the end side of the discharge pipe. Further, when urine and washing water flow through the bent portion of the discharge pipe, centrifugal force is generated in the urine and wash water at the central position in the pipe cross section of the discharge pipe due to the curvature of the bent portion. The first flow from the top to the top (or from the top to the bottom) is generated, and the pressure distribution is different because the pressure distribution is different between the top and bottom of the bent portion of the discharge pipe. A second flow is generated in the lower portion (or from the lower portion to the upper portion), and vortex flows are generated by the first flow and the second flow. Urination feces and washing water accompanied by vortex flow can be quickly discharged out of the discharge pipe. At this time, since the urinary stool and the washing water are sucked out with a strong suction action, there is an effect that the urination stool and the washing water do not adhere and accumulate in the discharge pipe.

  According to the fourth aspect of the present invention, since the bent portion is formed in the vicinity of the starting end of the discharge pipe, the space of the pipe cross section of the discharge pipe is hermetically sealed by blocking the small volume of urine feces and washing water at the bent portion. Alternatively, if suction is performed in this state, the inside of the discharge pipe on the lower side of the bent portion is in a negative pressure state, and the urine feces and the washing water are quickly conveyed toward the end side of the discharge pipe. Further, when urine and washing water flow through the bent portion of the discharge pipe, centrifugal force is generated in the urine and wash water at the central position in the pipe cross section of the discharge pipe due to the curvature of the bent portion. The first flow from the top to the top (or from the top to the bottom) is generated, and the pressure distribution is different because the pressure distribution is different between the top and bottom of the bent portion of the discharge pipe. A second flow is generated in the lower portion (or from the lower portion to the upper portion), and vortex flows are generated by the first flow and the second flow. Urination feces and washing water accompanied by vortex flow can be quickly discharged out of the discharge pipe. At this time, since a small volume of urinary stool and washing water are sucked out with a strong suction action, there is an effect that urination stool and washing water do not adhere and accumulate in the discharge pipe.

  According to the fifth aspect of the present invention, since the bent portion is formed in the vicinity of the end of the discharge pipe, a large volume of urine stool and washing water are blocked by the bent portion, so that the space of the pipe cross section of the discharge pipe is sealed. Alternatively, if suction is performed in this state, the inside of the discharge pipe on the lower side of the bent portion is in a negative pressure state, and the urine feces and washing water are quickly conveyed toward the outside of the end of the discharge pipe. Further, when urine and washing water flow through the bent portion of the discharge pipe, centrifugal force is generated in the urine and wash water at the central position in the pipe cross section of the discharge pipe due to the curvature of the bent portion. The first flow from the top to the top (or from the top to the bottom) is generated, and the pressure distribution is different because the pressure distribution is different between the top and bottom of the bent portion of the discharge pipe. A second flow is generated in the lower portion (or from the lower portion to the upper portion), and vortex flows are generated by the first flow and the second flow. Urination feces and washing water accompanied by vortex flow can be quickly discharged out of the discharge pipe. At this time, since large-capacity urination feces and washing water are sucked out with a strong suction action, there is an effect that urination feces and washing water do not adhere and accumulate in the discharge pipe.

  According to the sixth aspect of the present invention, since the bent portion bends the urinary stool passage upward, the urinary stool passage is blocked by the ridge portion of the bent portion formed in the discharge pipe, thereby blocking the urine toilet and the washing water. If the space is sealed or narrowed and suction is performed in this state, the inside of the urinary stool passage on the lower side of the bent part is in a negative pressure state, and the urinary stool and the washing water are quickly transported toward the end side of the discharge pipe. . Furthermore, when urine and flush water flow through the bent part of the discharge pipe, centrifugal force is generated in the urine and wash water at the central position in the tube cross section of the defecation passage due to the curvature of the bent part. A first flow is generated from the lower part to the upper part, and since the pressure distribution force acts because the pressure distribution is different between the upper part and the lower part of the bent part in the defecation passage, the second flow flows from the upper part to the lower part of the bent part. And eddy currents are generated by the first flow and the second flow. The urination feces and washing water accompanied by the vortex can be quickly discharged out of the urination passage.

  According to the seventh aspect of the present invention, since the bent portion bends the urinary stool passage downward, the urinary stool passage is stored by storing the urine stool and the washing water in the valley portion of the bent portion formed in the discharge pipe. If the space is sealed or narrowed and suction is performed in this state, the inside of the urinary stool passage on the lower side of the bent part is in a negative pressure state, and the urinary stool and the washing water are quickly transported toward the end side of the discharge pipe. . Furthermore, when urine and flush water flow through the bent part of the discharge pipe, centrifugal force is generated in the urine and wash water at the central position in the tube cross section of the defecation passage due to the curvature of the bent part. A first flow is generated from the upper part to the lower part, and since the pressure distribution is different because the pressure distribution is different between the upper part and the lower part of the bent part in the defecation passage, the second flow flows from the lower part to the upper part of the bent part. And eddy currents are generated by the first flow and the second flow. The urination feces and washing water accompanied by the vortex can be quickly discharged out of the urination passage.

Stored.

  A feature of the present invention is that a bent portion is formed in a part of the urination passage.

  That is, when the urination feces and washing water discharged from the patient P into the urination stool processing body 51 are transferred to the outside of the bedding bed 11 through the discharge pipe 103, the bent portion 150 is provided in a part of the urination stool passage. As a result, the urination feces and washing water are blocked, the water level rises, and the space above the urinary stool passage in the tube cross-sectional direction is sealed or narrowed. If suction is performed in this state, the upper space in the tube cross-section direction of the urine passage is sealed, so that the inside of the urine passage on the lower side of the dammed portion is in a negative pressure state. Water passes through the discharge passage 81, the check valve case 66, and the discharge pipe 103 of the urine / feces processing body 51 and is quickly transported toward the storage tank 300 of the excreta container D.

  Further, when the urine feces and the wash water flow through the bent portion 150 provided in the urine stool passage, the centrifugal force is applied to the urine feces and the wash water at the center position in the tube cross section of the urine stool passage due to the curvature of the bend portion 150. A first flow F1 is generated from the lower part 150b of the bent part 150 to the upper part 150a (or from the upper part 150a to the lower part 150b), and the pressure distribution is different between the upper part 150a and the lower part 150b of the bent part 150 of the urination passage. Therefore, when the pressure gradient force acts, the second flow F2 is generated from the upper part 150a to the lower part 150b (or from the lower part 150b to the upper part 150a) of the bent part 150, and the vortex flow caused by the first flow F1 and the second flow F2 F3 is generated. The urination feces and washing water with the vortex F3 can be quickly discharged out of the urination passage.

  Further, urination feces and washing water do not adhere and accumulate in the urination passage, and it is possible to prevent odor generated from the urination passage and always use it cleanly.

  The bent portion 150 is provided at one position in any position of the urination passage, but may be provided at a plurality of positions. According to such a configuration, it is possible to efficiently and reliably carry out the urination feces and the washing water in the urine passage from the start end side to the end side of the urination feces processing body 51 and the discharge pipe.

  Below, the Example which formed the bending part in a part of defecation passage is shown.

[Example 1]
In the first embodiment, an example in which the bent portion 150 is provided in the urination / feces receiving portion 82 of the urine / feces processing body 51 will be described. As described above, the urination / feces processing body 51 is formed with the urination / feces receiving portion 82 in the processing portion main body 56, and the urination / feces receiving portion 82 is provided with a discharge passage 81 for storing and discharging the urine and feces. It has been. An air bag 151 that is inflatable and expandable is disposed on the bottom 81 a on the lower side of the discharge passage 81. When the air bladder 151 is inflated, a bent portion 150 is formed in the discharge passage 81. That is, when air is injected from the air bag pump 160 through the third air pipe 161, the air bag 151 is inflated, and the space S of the discharge passage 81 is narrowed.

  Then, after the urination feces are discharged into the discharge passage 81 of the urination stool receiving part 82 and then the wash water is injected from the spray nozzle 105 to the urine stool, the urine stool and the wash water Z are inflated in the air bag 151. It will be in the state dammed up (refer FIG. 14). At this time, in the discharge passage 81, the space S of the discharge passage 81 is narrowed from the lower side to the upper side by the urination feces and washing water Z and the air bag 151 and is in a sealed state.

  Next, as shown in FIGS. 16 and 17, the discharge passage 81 is narrowed and sealed, and at the same time, the intake valve 409 is opened from the state of being evacuated by the vacuum tank 408, and the intake pipe 401 a and the exhaust pipe 103 are interposed. When sucked, the discharge passage 81 in the urine processing body 51 on the lower side of the dammed portion is in a negative pressure state, and a strong negative pressure is generated to flow the urine and washing water Z from the upper side to the lower side. Furthermore, the swirl F3 is generated in the urine and the wash water Z passing through the bent portion 150 of the discharge passage 81. That is, a centrifugal force is generated by the curvature of the bent portion 150 in the urinary stool and the washing water Z1 at the center position in the pipe cross section of the discharge passage 81, and a first flow F1 from the lower portion 150b of the bent portion 150 toward the upper portion 150a is generated. In addition, since the pressure distribution is different between the upper portion 150a and the lower portion 150b of the bent portion 150 in the discharge passage 81, the second flow F2 is generated from the upper portion 150a to the lower portion 150b of the bent portion 150, A vortex F3 due to the first flow F1 and the second flow F2 is generated. The urination feces and washing water Z accompanied with the vortex F3 are sucked out of the urine processing body 51 from the discharge port 102a through the check valve case 66, and further stored in the storage tank 300 through the discharge pipe 103 (FIG. 6). reference).
