Thus, both the suction hose and the blower hose are connected to the external device and are handled as one set. For this reason, the suction hose connection port 31 and the blower hose connection port 32 are preferably provided adjacent to each other.
Moreover, in order to make it easy to discharge the excrement received by the receiving part 40 from the discharge port 50, to make the height of the base part 20 arranged under the user's buttocks as low as possible, and to prevent pressure sores, Considering that the width of the left and right sides of the base 20 is as narrow as possible so that it can be easily turned over to the left and right, these are moved up and down so that the suction hose connection port 31 is on the lower side and the blower hose connection port 32 is on the upper side. It is preferable to arrange them side by side.

  Moreover, as shown in FIGS. 3-5, the branch part 60 which divides the air supplied from the external apparatus into two in the position corresponding to the ventilation hose connection port 32 in the inside of the standing part 30 is provided. Yes. The branch portion 60 is disposed so as to be positioned above the excrement discharge pipe 51 inside the rising portion 30 (inside the space S).

The branch portion 60 includes a trunk tube 61, an inclined tube 62, a first branch tube 63, and a second branch tube 64.
The trunk pipe 61 communicates with the blower hose connection port 32 and is coaxial with the blower hose connection port 32.
Further, the inclined pipe 62 is connected to the downstream side of the trunk pipe 61, and is inclined so that its axis forms an acute angle with respect to the axis of the trunk pipe 61. Specifically, the inclined pipe 62 extends obliquely downward from the downstream end portion of the trunk pipe 61 toward the receiving portion 40.

  The first branch pipe 63 is connected to the downstream side of the inclined pipe 62, and the axis thereof is inclined so as to form an acute angle with respect to the axis of the inclined pipe 62. Specifically, the first branch pipe 63 extends obliquely downward from the downstream end of the inclined pipe 62 toward the side of the excrement discharge pipe 51.

  The second branch pipe 64 is connected to the downstream side of the inclined pipe 62 and is inclined so that its axis forms an acute angle with respect to the axis of the inclined pipe 62. Specifically, the second branch pipe 64 is directed obliquely downward from the downstream end of the inclined pipe 62 to the side of the excrement discharge pipe 51 and to the side opposite to the first branch pipe 63. It extends.

For this reason, the air supplied from the trunk pipe 61 can smoothly flow through the inclined pipe 62 to the first branch pipe 63 and the second branch pipe 64, and noise associated with the blowing is generated. It can be difficult.
Therefore, it is possible to prevent the force of the air ejected from the blower port from becoming weak and to prevent the motor on the external device side for supplying air to the excrement disposal tool 10 from being loaded.

  As shown in FIGS. 3 to 5, an air chamber 70 is provided on the opposite side of the receiving portion 40 from the rising portion 30 (the discharge port 50 and the excrement discharge pipe 51). Specifically, an air chamber 70 is provided in the space S at a position corresponding to the opposite side of the rising portion 30 with the receiving portion 40 interposed therebetween. In the present embodiment, the air chamber 70 is formed using ABS resin.

The branch portion 60 and the air chamber 70 are communicated with each other by the first blower pipe 65 and the second blower pipe 66.
Specifically, the upstream side of the first blower pipe 65 is connected to the first branch pipe 63 of the branch part 60 and communicates with the branch part 60, and the downstream side of the first blower pipe 65 is connected to the air chamber 70. It is connected to the first connection portion 71 and communicates with the air chamber 70.
The upstream side of the second blower pipe 66 is connected to the second branch pipe 64 of the branch part 60 and communicates with the branch part 60, and the downstream side of the second blower pipe 66 is the second connection of the air chamber 70. It is connected to the portion 72 and communicates with the air chamber 70.

Here, assuming that the straight line passing through the center of the excrement discharge pipe 51, the center of the receiving portion 40, and the center of the air chamber 70 is a center line, the first blower pipe 65 and the second blower pipe 66 are inside the space S. These are arranged so as to extend from the branch part 60 to the air chamber 70 through both sides of the center line.
Specifically, as shown in FIG. 7, the first blower pipe 65 is arranged along one side of the receiving portion 40 inside the space S.
Moreover, the 2nd ventilation pipe 66 is arrange | positioned inside the space S so that the other side (opposite side to the 1st ventilation pipe 65) of the receiving part 40 may be followed.

That is, the 1st ventilation pipe 65 passes the side of the receiving part 40 from the 1st branch pipe 63 of the branch part 60 inside the space S, and the rising part 30 (discharge port 50, excrement) of the receiving part 40. It reaches the side opposite to the discharge pipe 51) and is connected to the first connection portion 71 of the air chamber 70.
In addition, in the space S, the second blower pipe 66 passes from the second branch pipe 64 of the branch part 60 to the side of the receiving part 40 and on the side opposite to the first blower pipe 65 to receive the receiving part. 40 reaches the side opposite to the rising portion 30 (the discharge port 50 and the excrement discharge pipe 51) and is connected to the second connection portion 72 of the air chamber 70.

  Moreover, the 1st ventilation pipe 65 and the 2nd ventilation pipe 66 are formed using the material which is hard to deform | transform. In this embodiment, the 1st ventilation pipe 65 and the 2nd ventilation pipe 66 use polypropylene (PP), and are formed by blow molding. In addition, you may form the 1st ventilation pipe 65 and the 2nd ventilation pipe 66 using PET.

Here, when a rubber tube is used as the first blower pipe 65 and the second blower pipe 66, for example, when the outer member 11 and the inner member 12 are combined, they may be deformed (bent or crushed). Moreover, if the 1st ventilation pipe 65 and the 2nd ventilation pipe 66 deform | transform, it will become impossible to supply air stably to a ventilation opening. Furthermore, if either the first blower pipe 65 or the second blower pipe 66 is deformed and the air supply amount varies between them, the ejection of air from the blower port becomes unstable. .
Therefore, in the present embodiment, the first blower pipe 65 and the second blower pipe 66 are formed by using a material that is not easily deformed, so that air is stably supplied to the blower port and the air is blown out from the blower port. Is not unstable.

As shown in FIGS. 9 to 11, the air chamber 70 includes a first connection portion 71 to which the first blower pipe 65 is connected, a second connection portion 72 to which the second blower pipe 66 is connected, The first air chamber 73 communicating with the first connection portion 71, the second air chamber 74 communicating with the second connection portion 72, the opposite side of the first air chamber 73 from the first connection portion 71, and the second air chamber 74.

Yes. The first air chamber 73 communicates with the first connection portion 71, and the second air chamber 74 communicates with the second connection portion 72. The connection air chamber 75 connects the side of the first air chamber 73 opposite to the first connection portion 71 and the side of the second air chamber 74 opposite to the second connection portion 72.

Further, the inner diameter of the first air chamber 73 on the first connection portion 71 side is formed larger than the inner diameter of the first blower pipe 65 on the air chamber 70 side. Further, the first air chamber 73 is formed such that the inner diameter gradually increases from the first connection portion 71 side toward the connection air chamber 75 side, and then the inner diameter gradually decreases. .
Further, the inner diameter of the second air chamber 74 on the second connection portion 72 side is formed larger than the inner diameter of the second air blowing pipe 66 on the air chamber 70 side. Furthermore, as with the first air chamber 73, the second air chamber 74 has an inner diameter that gradually increases from the second connection portion 72 side toward the connection air chamber 75 side, and then the inner diameter gradually decreases. It is formed to become.
Thus, both the first air chamber 73 and the second air chamber 74 are made to gradually increase in inner diameter toward the connected air chamber 75 side, whereby the first air pipe 65 and the second air fan The air supplied from the pipe 66 flows smoothly toward the connection air chamber 75, and noise associated with the blowing is less likely to occur.
Moreover, the 1st air chamber 73 and the 2nd air chamber 74 are made into the symmetrical shape.
In addition, the connection air chamber 75 has an inner diameter (volume) smaller than that of the first air chamber 73 and the second air chamber 74.

Also, as shown in FIG. 10, the air chamber 70 has a central air outlet 76 that opens as a blower opening at a position facing the discharge outlet 50 and the excrement discharge pipe 51, and openings on both sides of the central air outlet 76. A first blower port 77 and a second blower port 78 are provided.
The central air outlet 76 communicates with the connection air chamber 75 of the air chamber 70, the first air outlet 77 communicates with the first air chamber 73 of the air chamber 70, and the second air outlet 78 communicates with the air chamber 70. The second air chamber 74 communicates with the second air chamber 74.
Then, the air supplied from the first blower pipe 65 and the second blower pipe 66 is merged in the air chamber 70, and is exhausted from each of the central blower port 76, the first blower port 77, and the second blower port 78. It is made to eject toward the exit 50 and the excrement discharge pipe 51 direction.

That is, the first blower pipe 65 communicates with one side of the air chamber 70, and the second blower pipe 66 communicates with the side of the air chamber 70 opposite to the communication part of the first blower pipe 65.
The central air outlet 76 is provided at a position equidistant from the communication portion of the first air pipe 65 and the second air pipe 66 in the air chamber 70, and the first air outlet 77 is the central air outlet in the air chamber 70. The second air outlet 78 is provided at a position closer to the communication part of the second air pipe 66 than the central air outlet 76 in the air chamber 70. Yes.
The portion of the air chamber 70 where the central air outlet 76 is provided has a smaller inner diameter (volume) than the portion where the first air outlet 77 and the second air outlet 78 are provided.

As described above, in the present embodiment, the branch passage 60, the first blower pipe 65, the second blower pipe 66, and the air chamber 70 form a blower passage.
The air supplied from the external device is divided into two by a branching portion 60 provided at a position corresponding to the upper portion of the excrement discharge pipe 51.

  In addition, one of the air divided into two at the branch part 60 passes through the first blower pipe 65 disposed on the side of the receiving part 40 and reaches the side opposite to the excrement discharge pipe 51, and the other is Then, it passes through the second blower pipe 66 disposed on the side opposite to the first blower pipe 65 on the side of the receiving portion 40 and reaches the opposite side of the excrement discharge pipe 51.

  Furthermore, the air that has passed through the first blower pipe 65 and the air that has passed through the second blower pipe 66 merge in the air chamber 70 provided on the side opposite to the excrement discharge pipe 51, and then the central blower port 76. Then, the air is ejected from each of the first air outlet 77 and the second air outlet 78 toward the excrement discharge pipe 51.

  In particular, there are two air passages, a first air pipe 65 and a second air pipe 66, and there are three air outlets, a central air outlet 76, a first air outlet 77, and a second air outlet 78, By providing the air chamber 70 between them and merging the air there, air can be stably ejected from the central air outlet 76, the first air outlet 77, and the second air outlet 78.

  Further, in the air chamber 70, a first air blowing port 77 is opened between the first connection portion 71 and the central air blowing port 76, and a second air blowing port is formed between the second connection portion 72 and the central air blowing port 76. Although 78 is open, the inner diameter (volume) of the connection air chamber 75 is made smaller than the inner diameters (volume) of the first air chamber 73 and the second air chamber 74, so that the air blown out from the central air outlet 76 is the first air blower. It can be prevented from becoming weaker than the air blown from the mouth 77 or the second air blowing port 78.

Moreover, even if a gap or a crack is made in the base 20 laid under the user's buttocks due to the weight of the user, air can be prevented from leaking therefrom.
Furthermore, the passage of the air supplied from the external device is divided into two parts, the first air pipe 65 and the second air pipe 66, so that these respectively pass through both sides (positions off the center) of the receiving part 40. Therefore, the height of the receiving part 40 can be lowered correspondingly, and as a result, the height of the base 20 laid under the user's buttocks can be lowered.

Further, the central air outlet 76, the first air outlet 77, and the second air outlet 78 protrude toward the rising portion 30 from the peripheral portion opposite to the rising portion 30 (the discharge port 50 and the excrement discharge pipe 51). In order to do so, a current plate 80 is provided.
The rectifying plate 80 allows air blown from each of the central air outlet 76, the first air outlet 77, and the second air outlet 78 to flow along the surface of the receiving portion 40.
Thereby, the excrement in the receiving part 40 is made easy to float and is made easy to discharge.

Further, as shown in FIGS. 12 and 13, at the position corresponding to between the central air outlet 76 and the first air outlet 77 in the rectifying plate 80, from each of the central air outlet 76 and the first air outlet 77. A first auxiliary rectifying plate 81 that partitions the flow of the blown air is provided.
Similarly, at the position corresponding to between the central air outlet 76 and the second air outlet 78 in the rectifying plate 80, the second air that partitions the flow of air ejected from each of the central air outlet 76 and the second air outlet 78. An auxiliary rectifying plate 82 is provided.

Further, both the first auxiliary rectifying plate 81 and the second auxiliary rectifying plate 82 protrude downward (in the direction of the receiving portion 40) from the lower surface (the surface on the receiving portion 40 side) of the rectifying plate 80.
Thus, the air blown out from each of the central air outlet 76, the first air outlet 77, and the second air outlet 78 does not collide with each other, and the air flow in the receiving portion 40 is not disturbed. The excrement in the unit 40 can be effectively pushed out toward the discharge port 50 and the excrement discharge pipe 51.

Further, the upstream end portion of the branch portion 60, that is, the cross-sectional area of the trunk tube 61 is A.
Further, the cross-sectional area of the end portion on the branching portion 60 side of the first blower pipe 65 is B1, and the cross-sectional area of the end portion on the branching portion 60 side of the second blower pipe 66 is B2.
Further, the cross-sectional area of the end portion of the first blower pipe 65 on the air chamber 70 side is C1, and the cross-sectional area of the end portion of the second blower pipe 66 on the air chamber 70 side is C2.

Further, the area of the central air outlet 76 is D1, the area of the first air outlet 77 is D2, and the area of the second air outlet 78 is D3.
At this time, B1 = B2, C1 = C2, D2 = D3, and A <(B1 + B2) <(C1 + C2) <(D1 + D2 + D3) are satisfied.
That is, the 1st ventilation pipe 65 and the 2nd ventilation pipe 66 are made into a symmetrical shape, and it is made for the internal diameter of a ventilation passage to become thick gradually from an upstream to a downstream.

Here, if the inner diameter of the air passage is narrowed in the middle, the air pressure is increased at that location, but the air pressure is lowered. Thereby, the force of the air which blows off from the central ventilation port 76, the 1st ventilation port 77, and the 2nd ventilation port 78 becomes weak, and the excrement in the receiving part 40 is floated by extension, and the force to extrude becomes weak.
Moreover, if the inner diameter of the air passage is narrowed in the middle, a load is applied to the motor on the external device side for supplying air to the excrement disposal tool 10.

On the other hand, when the inner diameter of the air passage is gradually increased from the upstream side toward the downstream side, the air velocity gradually decreases, but the central air outlet 76, the first air outlet 77, and the second air blower. The force of the air ejected from the mouth 78 can be prevented from being weakened, and as a result, excrement can be floated in the receiving portion 40 and the force to be pushed out can be prevented from being weakened.
Further, when the inner diameter of the air passage is gradually increased from the upstream side toward the downstream side, it is possible to prevent a load from being applied to the motor on the external device side for supplying air to the excrement disposal tool 10.

Moreover, as shown in FIG. 14, the clearance gap between the front-end | tip of the baffle plate 80 and the surface of the receiving part 40 is set smaller than the center ventilation port 76, the 1st ventilation port 77, and the 2nd ventilation port 78. As shown in FIG. Yes.
Here, when the area of the gap formed between the tip of the current plate 80 and the surface of the receiving portion 40 is E, it is formed to satisfy E <(D1 + D2 + D3).
Thereby, although the internal diameter of a ventilation passage becomes thick gradually from the branch part 60 to the center ventilation port 76, the 1st ventilation port 77, and the 2nd ventilation port 78, it should narrow an air path finally. Thus, the speed of the air ejected toward the excrement in the receiving part 40 is increased, and as a result, the excrement in the receiving part 40 is easily floated and is easily discharged from the discharge port 50.

In the above-described embodiment, the air chamber 70 has a central air outlet 76 that opens at a position facing the excrement discharge pipe 51 and a first air outlet 77 that opens on both sides of the central air outlet 76 as air outlets. The second air outlet 78 is provided, but the present invention is not limited to this.
For example, as the air outlet, a central air outlet 76 that opens to a position facing the excrement discharge pipe 51, a first air outlet 77 and a second air outlet 78 that open on both sides of the central air outlet 76, and a first air outlet, respectively. The 3rd ventilation opening opened on the opposite side to the central ventilation opening 76 of the opening 77, and the 4th ventilation opening opened on the opposite side to the central ventilation opening 76 of the 2nd ventilation opening 78 can be provided.

That is, five air outlets may be provided side by side in the order of the third air outlet, the first air outlet 77, the central air outlet 76, the second air outlet 78, and the fourth air outlet.
Further, the central air outlet 76 communicates with the connected air chamber 75, the third air outlet and the first air outlet 77 communicate with the first air chamber 73, and the second air outlet 78 and the fourth air outlet are the second air chamber. 74 can be communicated.
And the air supplied with the 1st ventilation pipe 65 and the 2nd ventilation pipe 66 is merged in the air chamber 70, and this is made into the central ventilation port 76, the 1st ventilation port 77, the 2nd ventilation port 78, the 3rd ventilation port. And you may make it eject toward the excretion discharge pipe 51 direction from each of the 4th ventilation opening.

  Further, for example, two openings of the air outlet X and the air outlet Y are provided side by side at a position facing the excrement discharge pipe 51 in the air chamber 70. The blower port X is opened to the first blower port 77 side from the cleaning water nozzle 90, and the blower port Y is opened from the wash water nozzle 90 to the second blower port 78 side. Further, both the air blowing port X and the air blowing port Y are communicated with the connection air chamber 75. Then, the central air outlet 76 may be configured from the two openings of the air outlet X and the air outlet Y. That is, the central air outlet 76 may be configured by two or more openings.

In the above-described embodiment, A <(B1 + B2) <(C1 + C2) <(D1 + D2 + D3) is satisfied. However, A <(B1 + B2) = (C1 + C2) <(D1 + D2 + D3) may be satisfied. .
That is, about the 1st ventilation pipe 65 and the 2nd ventilation pipe 66, you may make an internal diameter equal from the edge part of these upstream sides to the edge part of a downstream side.

  For example, the receiving part 40 can be formed in a substantially U-shaped or substantially V-shaped cross section so that the height on the line connecting the excrement discharge pipe 51 and the air chamber 70 is the lowest. The first blower pipe 65 and the second blower pipe 66 pass through both sides of the line connecting the excrement discharge pipe 51 and the air chamber 70 below the receiving part 40 and from the branch part 60 to the air chamber 70. It can be formed to reach.
