It may be configured not to be provided.
　ビニールバッグ１１２の取付部１０２側の外周部には、循環装置６０から送風された空気を流入させる接続口としての流入部側接続口１１６とビニールバッグ１１２内部の空気を循環装置６０へ流出させる接続口としての流出部側接続口１１８が形成されている。流入部側接続口１１６は、ビニールバッグ１１２が膨張した際の外周形状が、後述する流入部１２０の内周形状と略同一となるように形成されている。また、流出部側接続口１１８は、ビニールバッグ１１２が膨張した際の外周形状が、後述する流出部１２２の内周形状と略同一となるように形成されている。 On the outer peripheral portion of the vinyl bag 112 on the mounting portion 102 side, an inflow portion side connection port 116 as a connection port for inflowing air blown from the circulation device 60 and a connection for discharging the air inside the vinyl bag 112 to the circulation device 60. The outflow portion side connection port 118 as a port is formed. The inflow portion side connection port 116 is formed so that the outer peripheral shape when the vinyl bag 112 is expanded is substantially the same as the inner peripheral shape of the inflow portion 120, which will be described later. Further, the outflow portion side connection port 118 is formed so that the outer peripheral shape when the vinyl bag 112 is expanded is substantially the same as the inner peripheral shape of the outflow portion 122, which will be described later.
　ビニールバッグ１１２のバッグ開口部１１２Ａの外周部には、外周に沿って輪状ゴム１１４が取り付けられている。これにより、図８に示されるように、ビニールバッグ１１２は、バッグ開口部１１２Ａの輪状ゴム１１４を、取付部１０２の装置上方側の外周部に取り付けた状態で回収容器１００の内側に配置されている。 A ring-shaped rubber 114 is attached to the outer peripheral portion of the bag opening 112A of the vinyl bag 112 along the outer peripheral portion. As a result, as shown in FIG. 8, the vinyl bag 112 is arranged inside the collection container 100 with the ring-shaped rubber 114 of the bag opening 112A attached to the outer peripheral portion of the attachment portion 102 on the upper side of the device. There is.
　収容部１０４の装置上方側（取付部１０２側）の外周部には、収容部１０４の径方向外側かつ取付部１０２側へ向けて傾斜して取り付けられると共に、両端部が開放された開口を有する略筒状に形成された流入部１２０が配置されている。 The outer peripheral portion of the accommodating portion 104 on the upper side (mounting portion 102 side) of the accommodating portion 104 is provided with an opening that is radially outward of the accommodating portion 104 and is inclined toward the mounting portion 102, and both ends are open. An inflow portion 120 formed in a substantially tubular shape is arranged.
　流入部１２０は、循環装置６０の空気吹出口６８とパイプＰＰを介して接続されており、循環装置６０からの空気が流入部１２０を介してビニールバッグ１１２の内部に流入可能に構成されている。 The inflow section 120 is connected to the air outlet 68 of the circulation device 60 via a pipe PP, and is configured so that air from the circulation device 60 can flow into the inside of the vinyl bag 112 via the inflow section 120. ..
　収容部１０４の装置上方側（取付部１０２側）の外周部には、両端部が開放された開口を有する略筒状に形成された流出部１２２が配置されている。流出部１２２は、循環装置６０の空気吸込口７０とパイプＰＰを介して接続されており、ビニールバッグ１１２の内部に流入した空気を循環装置６０へむけて流出可能に構成されている。 An outflow portion 122 formed in a substantially tubular shape having openings at both ends is arranged on the outer peripheral portion of the accommodating portion 104 on the upper side (mounting portion 102 side) of the device. The outflow portion 122 is connected to the air suction port 70 of the circulation device 60 via a pipe PP, and is configured so that the air flowing into the inside of the vinyl bag 112 can flow out toward the circulation device 60.
　次に、本実施形態の作用並びに効果について説明する。 Next, the operation and effect of this embodiment will be described.
　本実施形態に係るトイレ装置１０によれば、回収容器１００は、便座部８４に対して着脱可能に取り付けられた略筒形状の取付部１０２と全体形状が略筒状に形成されると共に取付部１０２に接続され、排泄物を収容可能な収容部１０４を備えている。このため、回収容器１００は、便座部８４に対して取り付けるだけの簡易な構成とすることができる。これにより、便座部８４側から排出され、収容部１０４に収容された排泄物を、便座部８４から回収容器１００を取り外すことにより簡便に処理することができる。 According to the toilet device 10 according to the present embodiment, the collection container 100 is formed with a substantially tubular mounting portion 102 detachably attached to the toilet seat portion 84 and a substantially tubular mounting portion as a whole. It is connected to 102 and includes a storage unit 104 capable of storing excrement. Therefore, the collection container 100 can be simply attached to the toilet seat portion 84. As a result, the excrement discharged from the toilet seat portion 84 side and stored in the storage portion 104 can be easily processed by removing the collection container 100 from the toilet seat portion 84.
　また、本実施形態に係るトイレ装置１０の収容部１０４には、その外筒部１１０の内周側に、取付部１０２へ向けて開放されたバッグ開口部１１２Ａを有するビニールバッグ１１２が配置されている。また、バッグ開口部１１２Ａ側の端部は、取付部１０２の便座部８４側の端部に取り付けられている。このため、排泄物をビニールバッグ１１２の内部に確実に収容することができる。さらに、外筒部１１０は、取付部１０２側と反対側の端部に貫通形成された孔を備えているため、回収容器１００の外筒部１１０の下端部は、装置下方側へ向けて開放されている。このため、空気が流入されたビニールバッグ１１２の膨張が回収容器１００の外筒部１１０の装置下方側端部で制限されない。これにより、排泄物をビニールバッグ１１２の内部に安定して滞留させることができる。 Further, in the accommodating portion 104 of the toilet device 10 according to the present embodiment, a vinyl bag 112 having a bag opening 112A opened toward the mounting portion 102 is arranged on the inner peripheral side of the outer cylinder portion 110. There is. Further, the end portion of the bag opening 112A side is attached to the end portion of the attachment portion 102 on the toilet seat portion 84 side. Therefore, the excrement can be reliably stored inside the vinyl bag 112. Further, since the outer cylinder portion 110 is provided with a hole formed through the end portion on the side opposite to the mounting portion 102 side, the lower end portion of the outer cylinder portion 110 of the collection container 100 is opened toward the lower side of the device. Has been done. Therefore, the expansion of the vinyl bag 112 into which the air has flowed in is not limited by the lower end of the outer cylinder 110 of the collection container 100. As a result, the excrement can be stably retained inside the vinyl bag 112.
　さらに、図９に示されるように、本実施形態に係るトイレ装置１０の収容部１０４の取付部１０２側の外周部に、収容部１０４の径方向外側かつ取付部１０２側へ向けて傾斜して取り付けられた流入部１２０を備えている。このため、流入部１２０からは、ビニールバッグ１１２の内周面を便座部８４側から底部１１２Ｂ側へ向けて螺旋状に旋回するようにビニールバッグ１１２へ空気が流入される。これにより、収容部１０４に収容された排泄物は、ビニールバッグ１１２の底部１１２Ｂ側へ滞留される。 Further, as shown in FIG. 9, the outer peripheral portion of the accommodating portion 104 of the toilet device 10 according to the present embodiment on the mounting portion 102 side is inclined outward in the radial direction of the accommodating portion 104 and toward the mounting portion 102 side. It includes an attached inflow section 120. Therefore, from the inflow portion 120, air flows into the vinyl bag 112 so as to spirally swirl the inner peripheral surface of the vinyl bag 112 from the toilet seat portion 84 side toward the bottom portion 112B side. As a result, the excrement contained in the accommodating portion 104 is retained on the bottom 112B side of the vinyl bag 112.
　また、循環装置６０と接続された補助気流流入部１０８から流入された空気は、ビニールバッグ１１２の取付部１０２側から底部１１２Ｂ側へ向けて流下し、ビニールバッグ１１２の底部１１２Ｂ側へ向けた風圧力を増加させる。これらのことから、ビニールバッグ１１２の底部１１２Ｂに滞留された排泄物をビニールバッグ１１２の取付部１０２側へ押し上げようとする力が生じないため、排泄物をビニールバッグ１１２の底部１１２Ｂに安定して滞留させることができる。 Further, the air flowing in from the auxiliary airflow inflow portion 108 connected to the circulation device 60 flows down from the attachment portion 102 side of the vinyl bag 112 toward the bottom 112B side, and the wind toward the bottom 112B side of the vinyl bag 112. Increase the pressure. From these facts, since the force for pushing the excrement accumulated in the bottom 112B of the vinyl bag 112 toward the attachment portion 102 side of the vinyl bag 112 is not generated, the excrement is stably transferred to the bottom 112B of the vinyl bag 112. Can be retained.
　収容部１０４は、その全体形状が、取付部１０２と反対側の端部の外径は、取付部１０２側端部の外径よりも大きく形成された略円錘台状に形成されている。図１０には、収容部１０４の上面から下面にかけての傾斜角（テーパ角）を変化した場合のビニールバッグ１１２の内部の空気の流速分布及び流線を数値シミュレーションした結果が示されている。図１０の左端のビニールバッグ１１２は、傾斜角が０度の場合、すなわち、回収容器１１０が円筒状に形成されている場合を示し、図１０の右端のビニールバッグ１１２は、傾斜角がθ２度（約２０度）と最も大きい場合を示す。図１０の真ん中のビニールバッグ１１２は、傾斜角がθ２度の半分のθ１度（約１０度）の場合を示す。傾斜角（テーパ角）が大きくなるにつれて、底部１１２Ｂ側の流れが安定し、装置水平方向に沿った円軌道になっていることがわかる。ビニールバッグ１１２の内周面を便座部８４側から底部１１２Ｂ側へ向けて螺旋状に旋回するように流入された空気は、ビニールバッグ１１２の底部１１２Ｂ側へ向かうにつれて、流速が低下すると共にビニールバッグ１１２の水平方向に沿った円軌道で旋回する。これらのことから、傾斜角（テーパ角）を大きくしたビニールバッグ１１２を形成することにより、その底部１１２Ｂに滞留された排泄物をビニールバッグ１１２の底部１１２Ｂに安定して滞留させることができる。 The overall shape of the accommodating portion 104 is formed in a substantially pedestal shape in which the outer diameter of the end portion on the side opposite to the mounting portion 102 is larger than the outer diameter of the end portion on the side of the mounting portion 102. FIG. 10 shows the results of numerical simulation of the flow velocity distribution and streamlines of the air inside the vinyl bag 112 when the inclination angle (taper angle) from the upper surface to the lower surface of the accommodating portion 104 is changed. The leftmost vinyl bag 112 in FIG. 10 shows a case where the inclination angle is 0 degrees, that is, the collection container 110 is formed in a cylindrical shape, and the rightmost vinyl bag 112 in FIG. 10 has an inclination angle of θ2 degrees. The largest case is shown (about 20 degrees). The vinyl bag 112 in the center of FIG. 10 shows a case where the inclination angle is θ1 degree (about 10 degrees), which is half of θ2 degrees. It can be seen that as the inclination angle (taper angle) increases, the flow on the bottom 112B side becomes stable and becomes a circular orbit along the horizontal direction of the device. The air flowing in so as to spirally swirl the inner peripheral surface of the vinyl bag 112 from the toilet seat 84 side toward the bottom 112B side decreases in flow velocity and goes toward the bottom 112B side of the vinyl bag 112, and the vinyl bag. It turns in a circular orbit along the horizontal direction of 112. From these facts, by forming the vinyl bag 112 having a large inclination angle (taper angle), the excrement accumulated in the bottom 112B of the vinyl bag 112 can be stably retained in the bottom 112B of the vinyl bag 112.
　図９及び図１１に示されるように、収容部１０４の取付部１０２側の外周部には、両端部が開放された開口を有する略筒状に形成され、ビニールバッグ１１２の内部の空気を流出させる流出部１２２が、取り付けられている。流出部１２２は、収容部１０４の外周部に、収容部１０４の径方向外側かつ取付部１０２側へ向けて傾斜して取り付けられている。このため、流入部１２０からビニールバッグ１１２の内周面を便座部８４側から底部１１２Ｂ側へ向けて螺旋状に旋回するように流入された空気を分散させることなく、ビニールバッグ１１２の便座部８４側の空気を流出させることができる。これにより、循環装置６０とビニールバッグ１１２の間で空気を効率よく循環させることができるため、空気を循環させるための電力の使用を抑制することができる。 As shown in FIGS. 9 and 11, the outer peripheral portion of the accommodating portion 104 on the mounting portion 102 side is formed in a substantially tubular shape having openings at both ends, and the air inside the vinyl bag 112 flows out. An outflow portion 122 is attached. The outflow portion 122 is attached to the outer peripheral portion of the accommodating portion 104 so as to be inclined outward in the radial direction of the accommodating portion 104 and toward the mounting portion 102. Therefore, the toilet seat portion 84 of the vinyl bag 112 does not disperse the air that has flowed in so as to spirally swirl the inner peripheral surface of the vinyl bag 112 from the inflow portion 120 from the toilet seat portion 84 side to the bottom portion 112B side. The air on the side can be drained. As a result, air can be efficiently circulated between the circulation device 60 and the vinyl bag 112, so that the use of electric power for circulating the air can be suppressed.
　以上説明したように、本実施形態に係るトイレ装置１０によれば、回収容器１００を簡易な構成とした上で空気を循環させるための電力の使用を抑制できる。 As described above, according to the toilet device 10 according to the present embodiment, it is possible to suppress the use of electric power for circulating air after the collection container 100 has a simple configuration.
　さらに、本実施形態に係るトイレ装置１０によれば、図１２に示されるように、循環装置６０の遠心ファン６４は、一方の端部にハンドル７８を取り付けたフレキシブルシャフト８０を動力連結部７６に接続することにより、手動で駆動することができる。このため、電力を使用することなく、空気を循環させることができる。 Further, according to the toilet device 10 according to the present embodiment, as shown in FIG. 12, the centrifugal fan 64 of the circulation device 60 has a flexible shaft 80 having a handle 78 attached to one end thereof as a power connecting portion 76. By connecting, it can be driven manually. Therefore, air can be circulated without using electric power.
　また、本実施形態に係るトイレ装置１０は、図１３から図１４Ｂに示されるように、便座部８４に着座した使用者Ｐの大腿部を保持する体固定機構１２を備えている。図１３に示されるように、体固定機構１２は、アーム接続部５２を備えることにより、便座部８４に着座した使用者Ｐに対する太腿保持部４０の人体左右方向位置（装置幅方向位置）を調整可能とされている。また、図１４Ａ及び図１４Ｂに示されるように、体固定機構１２は、高さ調整部３６を備えることにより、便座部８４に着座した使用者Ｐに対する太腿保持部４０の人体上下方向位置（装置上下方向位置）を調整可能とされている。このため、便座部８４に着座した使用者Ｐの体型に合わせて大腿部ＦＥを保持板４０Ａにより保持することができ、排泄物を確実に回収容器１００の収容部１０４に排出させることができる。 Further, as shown in FIGS. 13 to 14B, the toilet device 10 according to the present embodiment includes a body fixing mechanism 12 for holding the thigh of the user P seated on the toilet seat portion 84. As shown in FIG. 13, the body fixing mechanism 12 includes the arm connecting portion 52, so that the position of the thigh holding portion 40 in the human body left-right direction (position in the device width direction) with respect to the user P seated on the toilet seat portion 84 can be determined. It is said to be adjustable. Further, as shown in FIGS. 14A and 14B, the body fixing mechanism 12 includes the height adjusting portion 36, so that the position of the thigh holding portion 40 in the vertical direction of the human body with respect to the user P seated on the toilet seat portion 84 ( The vertical position of the device) can be adjusted. Therefore, the thigh FE can be held by the holding plate 40A according to the body shape of the user P seated on the toilet seat portion 84, and the excrement can be reliably discharged to the accommodating portion 104 of the collection container 100. ..
（変形例）
　次に、図１５から図１８を用いて、本発明に係る微小重力空間用トイレの変形例について説明する。なお、前述した実施形態と同一構成部分については、同一番号を付してその説明を省略する。 (Modification example)
Next, a modified example of the toilet for microgravity space according to the present invention will be described with reference to FIGS. 15 to 18. The same components as those in the above-described embodiment are designated by the same numbers, and the description thereof will be omitted.
　図１５には、本実施形態に係る微小重力空間用トイレとしてのトイレ装置１３０の一例が示されている。このトイレ装置１３０では、回収容器１００に加えて、尿用の回収容器としての尿回収容器１３２が設けられている。尿回収容器１３２は、その装置後方側を形成する取付部１３４と、装置前方側を形成する収容部１０４と、を含んで構成されている。 FIG. 15 shows an example of the toilet device 130 as a toilet for a microgravity space according to the present embodiment. In the toilet device 130, in addition to the collection container 100, a urine collection container 132 as a collection container for urine is provided. The urine collection container 132 includes an attachment portion 134 forming the rear side of the device and a storage portion 104 forming the front side of the device.
　図１６に示されるように、取付部１３４は、両端部に開口を備えた略筒状に形成されている。取付部１３４の装置前方側には、全体形状が、前面と後面が開口された略円錐台状に形成された収容部が取り付けられている。収容部１０４は、その外側部分を形成する外筒部１１０と、外筒部１１０の内周面に沿って配置された袋部としてのビニールバッグ１１２（図７参照）と、を含んで構成されている。 As shown in FIG. 16, the mounting portion 134 is formed in a substantially tubular shape having openings at both ends. On the front side of the device of the mounting portion 134, a housing portion having an overall shape formed in a substantially truncated cone shape with front and rear surfaces opened is mounted. The accommodating portion 104 is configured to include an outer cylinder portion 110 forming an outer portion thereof and a vinyl bag 112 (see FIG. 7) as a bag portion arranged along the inner peripheral surface of the outer cylinder portion 110. ing.
　収容部１０４の装置後方側（取付部１３４側）の外周部には、両端部が開放された開口を有する略筒状に形成されると共に、収容部１０４の外周部に、収容部１０４の径方向外側かつ取付部１３４と反対側（装置前方側）へ向けて傾斜して取り付けられた流出部１３６が配置されている。また、流出部１３６は、循環装置６０の空気吸込口７０とパイプＰＰを介して接続されており、ビニールバッグ１１２の内部に流入した空気を循環装置６０へむけて流出可能に構成されている。 The outer peripheral portion of the accommodating portion 104 on the rear side of the device (mounting portion 134 side) is formed in a substantially tubular shape having openings at both ends, and the outer peripheral portion of the accommodating portion 104 has a diameter of the accommodating portion 104. An outflow portion 136 that is attached so as to be inclined toward the outside in the direction and the side opposite to the attachment portion 134 (the front side of the device) is arranged. Further, the outflow portion 136 is connected to the air suction port 70 of the circulation device 60 via a pipe PP, and is configured so that the air flowing into the inside of the vinyl bag 112 can flow out toward the circulation device 60.
　本変形例に係るトイレ装置１３０は、図１７に示されるように、収容部１０４の取付部１３４側の外周部に、収容部１０４の径方向外側かつ取付部１０２側へ向けて傾斜して取り付けられた流入部１２０を備えている。このため、流入部１２０からは、ビニールバッグ１１２の内周面を収容部１０４側から底部１１２Ｂ側へ向けて螺旋状に旋回するようにビニールバッグ１１２へ空気が流入される。これにより、収容部１０４に収容された尿（排泄物）は、ビニールバッグ１１２の底部１１２Ｂ側へ滞留される。 As shown in FIG. 17, the toilet device 130 according to this modification is attached to the outer peripheral portion of the accommodating portion 104 on the mounting portion 134 side at an angle toward the radial outer side of the accommodating portion 104 and the mounting portion 102 side. The inflow portion 120 is provided. Therefore, from the inflow portion 120, air flows into the vinyl bag 112 so as to spirally swirl the inner peripheral surface of the vinyl bag 112 from the accommodating portion 104 side toward the bottom portion 112B side. As a result, the urine (excrement) contained in the accommodating portion 104 is retained on the bottom 112B side of the vinyl bag 112.
　また、図１８に示されるように、収容部１０４の取付部１３４側の外周部には、流出部１３６が、取り付けられている。流出部１３６は、収容部１０４の外周部に、収容部１０４の径方向外側かつ取付部１３４側と反対側へ向けて傾斜して取り付けられている。このため、流入部１２０からビニールバッグ１１２の内周面を取付部１３４側から底部１１２Ｂ側へ向けて螺旋状に旋回するように流入された空気を分散させることなく、ビニールバッグ１１２の取付部１３４側の空気を流出させることができる。これにより、循環装置６０とビニールバッグ１１２の間で空気を効率よく循環させることができるため、空気を循環させるための電力の使用を抑制できる。 Further, as shown in FIG. 18, an outflow portion 136 is attached to the outer peripheral portion of the accommodating portion 104 on the attachment portion 134 side. The outflow portion 136 is attached to the outer peripheral portion of the accommodating portion 104 so as to be inclined toward the radial outer side of the accommodating portion 104 and the side opposite to the mounting portion 134 side. Therefore, the mounting portion 134 of the vinyl bag 112 does not disperse the air that has flowed in so as to spirally swirl the inner peripheral surface of the vinyl bag 112 from the inflow portion 120 from the mounting portion 134 side to the bottom 112B side. The air on the side can be drained. As a result, air can be efficiently circulated between the circulation device 60 and the vinyl bag 112, so that the use of electric power for circulating the air can be suppressed.
　さらに、本変形例に係るトイレ装置１３０によれば、尿回収容器１３２は、取付部１３４と取付部１３４に接続され、排泄物を収容可能な収容部１０４だけの簡易な構成とすることができる。これにより、ビニールバッグ１１２に収容された尿（排泄物）を、尿回収容器１３２からビニールバッグ１１２を取り外すことで簡便に処理することができる。 Further, according to the toilet device 130 according to the present modification, the urine collection container 132 can be connected to the attachment portion 134 and the attachment portion 134, and can have a simple configuration of only the accommodating portion 104 capable of accommodating excrement. .. As a result, the urine (excrement) contained in the vinyl bag 112 can be easily processed by removing the vinyl bag 112 from the urine collection container 132.
　なお、ここでは、トイレ装置１０、１３０は、便座部８４を備えているとして説明したが、これに限らず、例えば、男性の排尿に特化したトイレ装置として便座部を設けないトイレ装置が構成されてもよい。 Although the toilet devices 10 and 130 have been described here as having the toilet seat portion 84, the present invention is not limited to this, and for example, a toilet device not provided with the toilet seat portion is configured as a toilet device specialized for male urination.
