<<本実施形態に係る***物吸引装置の構成>>
先ず、本実施形態に係る***物吸引装置(以下、***物吸引装置1)の構成について図1乃至図8を参照しながら説明する。 << Configuration of the waste suction device according to the present embodiment >>
First, the configuration of the excrement suction apparatus (hereinafter, excrement suction apparatus 1) according to the present embodiment will be described with reference to FIGS. 1 to 8.
先ず、本実施形態に係る***物吸引装置(以下、***物吸引装置1)の構成について図1乃至図8を参照しながら説明する。 << Configuration of the waste suction device according to the present embodiment >>
First, the configuration of the excrement suction apparatus (hereinafter, excrement suction apparatus 1) according to the present embodiment will be described with reference to FIGS. 1 to 8.
***物吸引装置1は、図1に示す外観をなしており、歩行困難な患者や寝たきりの高齢者(以下、ユーザU)の***物の処理に利用される。
The excrement suction apparatus 1 has the appearance shown in FIG. 1 and is used to process excrement of a patient who is difficult to walk or a bedridden elderly person (hereinafter, user U).
図1及び図2に示されるように、***物吸引装置1は、ユーザUが直接装着するカップ部材10、装置本体30、カップ部材10及び装置本体30を接続する吸引ホース51、洗浄水ホース52、エア返送ホース53及び信号伝送ケーブル54を備える。
As shown in FIG. 1 and FIG. 2, the excrement suction apparatus 1 has a suction hose 51 for connecting the cup member 10, the device body 30, the cup member 10 and the device body 30 directly attached by the user U, and a flush water hose 52. , An air return hose 53 and a signal transmission cable 54.
吸引ホース51は、***物吸引用のホースである。吸引ホース51の一端部(カップ部材10に接続されている側の端部)は、カップ部材10の底壁を貫通しており、カップ部材10の底壁とユーザの股間部との間の空間に臨んでいる。吸引ホース51の他端部(カップ部材10に接続されている側とは反対側の端部)は、***物収容器20に接続されている。カップ部材10が底壁にて受けた***物Dは、***物吸引装置1によって吸引される際に吸引ホース51の内部を通って***物収容器20まで搬送される。
The suction hose 51 is a hose for suctioning excrement. One end (the end on the side connected to the cup member 10) of the suction hose 51 penetrates the bottom wall of the cup member 10, and a space between the bottom wall of the cup member 10 and the crotch of the user I am facing The other end (the end opposite to the side connected to the cup member 10) of the suction hose 51 is connected to the waste container 20. The excrement D received by the cup member 10 at the bottom wall is conveyed to the excrement container 20 through the inside of the suction hose 51 when being aspirated by the excrement suction device 1.
洗浄水ホース52は、洗浄水供給用のホースである。洗浄水ホース52は、図6に示す洗浄部60から供給されてくる洗浄水の流路をなしている。洗浄水ホース52の一端部(カップ部材10に接続されている側の端部)は、カップ部材10を貫通しており、カップ部材10とユーザの股間部(具体的には、股間部中、腹側よりも背側に位置する部分)との間の空間に臨んでいる。したがって、洗浄部60から洗浄水が供給されると、洗浄水がユーザの身体中、カップ部材10があてがわれている部位、すなわち、股間部に向けて洗浄水ホース52内を流れる。そして、最終的に洗浄水ホース52の一端側開口(具体的には洗浄水用ノズル16)から噴出する。
The washing water hose 52 is a hose for washing water supply. The washing water hose 52 constitutes a flow path of the washing water supplied from the washing unit 60 shown in FIG. One end (the end on the side connected to the cup member 10) of the flush water hose 52 penetrates the cup member 10, and the cup member 10 and the crotch of the user (specifically, in the crotch) It faces the space between the part located on the back side rather than the ventral side. Therefore, when the washing water is supplied from the washing unit 60, the washing water flows in the washing water hose 52 in the body of the user toward the portion where the cup member 10 is applied, that is, the crotch. And finally, it ejects from the one end side opening (specifically, nozzle 16 for wash water) of the wash water hose 52. As shown in FIG.
なお、ユーザの身体に向けて噴出した洗浄水は、***物Dと同様、カップ部材10に受けられて吸引ホース51を通じて吸引されて***物収容器20まで搬送される。
The wash water spouted toward the user's body is received by the cup member 10 and sucked through the suction hose 51 and transported to the waste container 20 as with the excrement D.
エア返送ホース53は、空気返送用のホースである。エア返送ホース53は、吸引ホース51を通じて***物Dや洗浄水を吸引する際に、これらと一緒に吸引されたカップ部材10内の空気を再びカップ部材10内に返送するための流路をなしている。エア返送ホース53の一端部(カップ部材10に接続されている側の端部)は、カップ部材10を貫通しており、カップ部材10とユーザの股間部(具体的には、股間部中、腹側よりも背側に位置する部分)との間の空間に臨んでいる。***物Dや洗浄水と共に吸引された空気は、***物吸引装置1内部を通過した後に、空気がユーザの身体中、カップ部材10があてがわれている部位、すなわち、股間部に向けてエア返送ホース53の内部を流れる。そして、最終的にエア返送ホース53の一端側開口(具体的にはエア吹出口14)から放出される。
The air return hose 53 is a hose for air return. The air return hose 53 has a flow path for returning the air in the cup member 10 sucked together with the waste D and the washing water again into the cup member 10 when the excrement D and the washing water are sucked through the suction hose 51. ing. One end of the air return hose 53 (the end connected to the cup member 10) passes through the cup member 10, and the cup member 10 and the crotch of the user (specifically, in the crotch, It faces the space between the part located on the back side rather than the ventral side. After the air sucked with the excrement D and the wash water passes through the excrement aspiration apparatus 1, the air is directed to the area where the cup member 10 is applied in the user's body, that is, toward the crotch area. It flows inside the return hose 53. Then, the air is finally discharged from one end side opening (specifically, the air outlet 14) of the air return hose 53.
つまり、カップ部材10内の空気は、カップ部材10内部と***物吸引装置1の装置本体30内部との間で循環することになる。これにより、排便時の臭気をカップ部材10内部及び***物吸引装置1の装置本体30内部に留めておき、当該臭気が外部に漂うのを極力抑えることが可能となる。
That is, the air in the cup member 10 is circulated between the inside of the cup member 10 and the inside of the apparatus main body 30 of the excrement suction apparatus 1. Thereby, it is possible to keep the odor at the time of defecation inside the cup member 10 and the inside of the device main body 30 of the excrement suction device 1, and to minimize the drift of the odor to the outside.
また、信号伝送ケーブル54は、カップ部材10内の物体を検出する検出部としての電極部15からの検出信号を***物吸引装置1の装置本体30側に送出するための伝送路である。なお、上記の「物体」とは例えば***物である。また、本実施形態では、上記の「検出部」として電極を利用する例について説明するが、上記の「検出部」は、電極式のセンサ、静電容量式のセンサ、光学式のセンサ、熱感知式のセンサ等の各種センサのうち一種、又は複数種を組み合わせてもよい。本実施形態では、上記の「検出部」を電極により構成することにより、複数種のセンサを用いる場合よりも、コスト低減、構造の簡素化を図ることができる。
そして、電極部15からの検出信号は、信号伝送ケーブル54を介して***物吸引装置1の動作を制御するコントローラ80に入力される。 Further, thesignal transmission cable 54 is a transmission path for transmitting a detection signal from the electrode unit 15 as a detection unit for detecting an object in the cup member 10 to the apparatus main body 30 side of the excrement suction apparatus 1. In addition, said "object" is excrement, for example. Further, in the present embodiment, an example in which an electrode is used as the above-described “detection unit” will be described. However, the “detection unit” described above includes an electrode sensor, a capacitance sensor, an optical sensor, and a thermal sensor. One or more of various sensors such as a sensing sensor may be combined. In the present embodiment, by configuring the above-mentioned “detection unit” by the electrodes, cost reduction and simplification of the structure can be achieved as compared with the case of using a plurality of types of sensors.
Then, the detection signal from theelectrode unit 15 is input to the controller 80 that controls the operation of the excrement suction apparatus 1 through the signal transmission cable 54.
そして、電極部15からの検出信号は、信号伝送ケーブル54を介して***物吸引装置1の動作を制御するコントローラ80に入力される。 Further, the
Then, the detection signal from the
次に、***物吸引装置1のカップ部材10の構成、及び***物吸引装置1の動作の概要について説明する。
Next, the structure of the cup member 10 of the excretion suction apparatus 1 and the outline | summary of operation | movement of the excretion suction apparatus 1 are demonstrated.
図2に示すように、ユーザUは、***部位Eをカップ部材10でカバーした状態で、カップ部材10の上からオムツPを装着する。そして、ユーザUは、例えば仰向きや、若干上体を起こした状態で***する。すると、***物吸引装置1は、カップ部材10内の***物を検知し、***物の種類を判定する。なお、上記の***物の種類とは、便(大便)又は尿である。
As shown in FIG. 2, the user U wears the diaper P from above the cup member 10 in a state where the excretory part E is covered by the cup member 10. Then, the user U excretes, for example, in a supine position or in a state of being slightly raised. Then, the excretion suction apparatus 1 detects the excretion in the cup member 10, and determines the kind of excretion. In addition, the said kind of excretion is stool (stool) or urine.
より詳しく説明すると、図4に示されるように、カップ部材10は、ユーザUの***部位Eを覆う第1カバー部材11と、ユーザUの臀部のうち背中側に位置する部分にあてがわれる第2カバー部材12を有する。第2カバー部材12は、第1カバー部材11の後端から略垂直に立ち上がる方向に延出し、カップ部材10は側面視において略L字の外形形状をなす。
More specifically, as shown in FIG. 4, the cup member 10 is applied to the first cover member 11 covering the excretory site E of the user U, and a part of the buttocks of the user U positioned on the back side 2 has a cover member 12. The second cover member 12 extends in a direction to rise substantially vertically from the rear end of the first cover member 11, and the cup member 10 has a substantially L-shaped external shape in a side view.
第1カバー部材11は、カップ部材10内に***された***物を受ける受け面11aと、受け面11aに***物を誘導する誘導面11bを有する。そして、受け面11aと誘導面11bの周囲には、受け面11aと誘導面11bから垂直に立ち上がり、カップ部材10の装着時に人体に密着する壁部11cが形成されている。これにより、カップ部材10の装着時に、人体、受け面11a、誘導面11b及び壁部11cによる閉空間(以下、***物貯留空間)が形成される。この***物貯留空間には、ユーザの***物が一時的に溜められる。
The first cover member 11 has a receiving surface 11a for receiving excrement excreted in the cup member 10, and a guiding surface 11b for guiding the excrement to the receiving surface 11a. Then, around the receiving surface 11a and the guiding surface 11b, there is formed a wall portion 11c which stands vertically from the receiving surface 11a and the guiding surface 11b and is in close contact with the human body when the cup member 10 is attached. Thereby, at the time of mounting | wearing of the cup member 10, the closed space (following, excrement storage space) by a human body, the receiving surface 11a, the guidance surface 11b, and the wall part 11c is formed. The excrement of the user is temporarily accumulated in the excrement storage space.
図5に示されるように、第1カバー部材11の受け面11aには、複数の電極15cからなる電極部15が設けられている。この電極部15は、受け面11aの中心部に配される第1電極ペア15aと、第1電極ペア15aの周囲に配される複数(本例においては3つ)の第2電極ペア15bを有する。第1電極ペア15aと第2電極ペア15bはそれぞれ、プラス極とマイナス極の二つの電極15cの組からなり、***物が電極ペアのプラス極とマイナス極に接触している場合には、***物が導体となって、電極ペアに電流が流れる。
ここで、それぞれの電極15cには、金等の金属によるめっきを施すことにより、腐食耐性を強化することとしてよい。
なお、洗浄水と、***物とでは導電率が相違するために、電極ペアに流れる電流値の大きさに基づいて、受け面11aに***物があるか否かを判定することができる。なお、***物の検出、及び***物の種類の判定処理の詳細については後述する。 As shown in FIG. 5, anelectrode portion 15 formed of a plurality of electrodes 15 c is provided on the receiving surface 11 a of the first cover member 11. The electrode portion 15 includes a first electrode pair 15a disposed at the center of the receiving surface 11a, and a plurality of (three in this example) second electrode pairs 15b disposed around the first electrode pair 15a. Have. The first electrode pair 15a and the second electrode pair 15b each consist of a pair of two electrodes 15c of plus and minus poles, and when excrement is in contact with the plus and minus poles of the electrode pair, excretion The object becomes a conductor and current flows in the electrode pair.
Here, the corrosion resistance may be enhanced by plating each of theelectrodes 15c with a metal such as gold.
In addition, since the conductivity is different between the washing water and the excrement, it can be determined whether or not the excrement is present on the receivingsurface 11a based on the magnitude of the current value flowing to the electrode pair. The details of the detection of the excrement and the determination process of the type of the excrement will be described later.
ここで、それぞれの電極15cには、金等の金属によるめっきを施すことにより、腐食耐性を強化することとしてよい。

また、図5に示されるように、第1電極ペア15aは、ユーザUの肛門に対向する位置に配することで、受け面11aで受け止めた便を検出しやすくなる。また、第1電極ペア15aの周囲に3つの第2電極ペア15bを設け、各第2電極ペア15bを第1電極ペア15aに対して略120度の角度ずつずらして配置する。これにより、ユーザUの体勢(右向きか左向きか、仰向けか上体起こしか)によらず、***物が検出されやすくなる。すなわち、ユーザUの体勢が変わると、鉛直方向に対する受け面11aの角度が変化し、受け面11aにおいて***物が置かれやすい部位が変わるが、こうした場合でも3つの第2電極ペア15bのいずれかにおいて***物を検出することが可能となる。
Further, as shown in FIG. 5, the first electrode pair 15 a is easy to detect stool received by the receiving surface 11 a by arranging the first electrode pair 15 a at a position facing the anus of the user U. In addition, three second electrode pairs 15b are provided around the first electrode pair 15a, and each second electrode pair 15b is disposed at an angle of approximately 120 degrees with respect to the first electrode pair 15a. As a result, regardless of the posture of the user U (rightward or leftward, supine or raised), excrement is easily detected. That is, when the posture of the user U changes, the angle of the receiving surface 11a with respect to the vertical direction changes, and the site where excrement tends to be placed changes in the receiving surface 11a. Even in such a case, any one of the three second electrode pairs 15b It is possible to detect excrement at
そして、上記の電極部15により***物が検出された場合に、***物吸引装置1では、洗浄処理と、***物の吸引処理の動作を開始する。以下、***物吸引装置1に設けられた、洗浄処理と吸引処理を実現する構成について説明する。

図3及び図6に示すように、装置本体30は、その内部に***物収容器20を格納し、***物収容器20内を減圧することでカップ部材10内の***物Dを***物収容器20内に吸引する。より詳しく説明すると、装置本体30が***物収容器20内を減圧すると、これに伴って、***物収容器20に接続された吸引ホース51内、及び、吸引ホース51の末端部に連通する***物貯留空間(カップ部材10とユーザの股間部との間の空間)が減圧される。これにより、装置本体30は、カップ部材10が受けた***物Dを、吸引ホース51を通じて***物収容器20内に吸引する。このとき、装置本体30は、カップ部材10内で噴出された洗浄水、及び、カップ部材10内に返送された空気と共に***物Dを吸引する。
As shown in FIGS. 3 and 6, the device body 30 stores the excrement container 20 therein, and depressurizes the excrement container 20 to store excrement D in the cup member 10. Suction into the vessel 20. Describing in more detail, when the device body 30 reduces the pressure in the excrement container 20, the excretory fluid communicating with the inside of the suction hose 51 connected to the excrement container 20 and the end of the suction hose 51 The object storage space (the space between the cup member 10 and the crotch of the user) is depressurized. Thereby, the device main body 30 sucks the excrement D received by the cup member 10 into the excrement container 20 through the suction hose 51. At this time, the device body 30 suctions the excrement D together with the washing water jetted out in the cup member 10 and the air returned into the cup member 10.
装置本体30は、図3及び図6に示すように、ケース部としてのケースユニット35と、吸引部40と、洗浄部60とを有する。これらの各ユニットは、装置本体30のハウジング31内に収納されている。以下、***物吸引装置1の各構成機器のうち、ケースユニット35、吸引部40、洗浄部60及び***物収容器20について説明する。
The apparatus body 30 has a case unit 35 as a case unit, a suction unit 40, and a cleaning unit 60, as shown in FIGS. 3 and 6. Each of these units is housed in the housing 31 of the device body 30. Hereinafter, the case unit 35, the suction part 40, the washing part 60, and the excrement container 20 among the component devices of the excrement suction apparatus 1 will be described.
ケースユニット35は、例えば合成樹脂(一例としてABS(アクリロニトリル-ブタジエン-スチレン共重合合成樹脂))製の有底箱状の容器であり、その内部に***物収容器20を収めることが可能である。ケースユニット35は、上端に開口部を有する。すなわち、ケースユニット35内の***物収容器20は、ケースユニット35の上端の開口部から取り出すことが可能である。なお、本実施形態において、ケースユニット35は、***物収容器20全体を収容するために幾分深底となっており、***物収容器20の高さよりも若干大きい高さを有している。
The case unit 35 is, for example, a bottomed box-like container made of a synthetic resin (for example, ABS (acrylonitrile-butadiene-styrene copolymer synthetic resin) as an example), and the excrement container 20 can be accommodated therein. . The case unit 35 has an opening at the upper end. That is, the waste container 20 in the case unit 35 can be taken out from the opening at the upper end of the case unit 35. In the present embodiment, the case unit 35 has a somewhat deep bottom to accommodate the entire waste container 20, and has a height slightly larger than the height of the waste container 20. .
また、ケースユニット35は、図3に示すように、横長なハウジング31の内部のうち、奥行方向(すなわち、ハウジング31の長手方向)における手前側に位置する空間に配置されている。より詳しく説明すると、ハウジング31の上壁(ハウジング上壁31a)のうち、奥行方向の手前側に位置する部分には略方形状の開口部が設けられている。ケースユニット35は、当該開口部からハウジング31内に挿入されることで、ハウジング31の内部中、奥行方向の手前側に配置されるようになる。なお、本実施形態において、奥行方向の「手前側」とは、ケースユニット35が配置される側に対応し、「奥側」とは、ケースユニット35が配置される側とは反対側に対応する。
Further, as shown in FIG. 3, the case unit 35 is disposed in a space located on the near side in the depth direction (that is, the longitudinal direction of the housing 31) of the inside of the horizontally long housing 31. More specifically, a substantially square opening is provided in a portion of the upper wall (the housing upper wall 31a) of the housing 31 located on the front side in the depth direction. When the case unit 35 is inserted into the housing 31 from the opening, the case unit 35 is disposed inside the housing 31 on the near side in the depth direction. In the present embodiment, the “front side” in the depth direction corresponds to the side on which the case unit 35 is disposed, and the “back side” corresponds to the side opposite to the side on which the case unit 35 is disposed Do.
また、ケースユニット35が有する側壁のうち、奥行方向において奥側の端部に位置する側壁には、図3及び図6に示すように、矩形状の吸気口36が形成されている。この吸気口36は、奥側の端部に位置するケースユニット35の側壁の上側部分に設けられている。さらに、図3及び図6に示すように、ケースユニット35の内部において、吸気口36と***物収容器20との間のスペースには、吸引フィルタ37が設置されている。吸引フィルタ37は、幾分の厚みを有するパネル状の部材である。
Moreover, as shown in FIG.3 and FIG.6, the rectangular-shaped inlet port 36 is formed in the side wall located in the edge part by the side of the back in a depth direction among the side walls which case unit 35 has. The intake port 36 is provided in the upper portion of the side wall of the case unit 35 located at the rear end. Furthermore, as shown in FIG. 3 and FIG. 6, in the case unit 35, a suction filter 37 is installed in the space between the intake port 36 and the excrement container 20. The suction filter 37 is a panel-like member having a certain thickness.
そして、吸引フィルタ37は、ケースユニット35に取り付けられた状態では吸気口36を覆っている。これにより、ケースユニット35内の空気が吸気口36を通過する直前で空気中の異物等が吸引フィルタ37によって捕捉されるようになる。
The suction filter 37 covers the air inlet 36 in a state of being attached to the case unit 35. As a result, immediately before the air in the case unit 35 passes through the air inlet 36, foreign substances and the like in the air are captured by the suction filter 37.
また、図1及び図3に示すように、ケースユニット35には、ケースユニット35の上端開口を塞ぐ蓋部(以下、第1蓋部32)が取り付けられている。この第1蓋部32は、ハウジング上壁31aの一部を構成し、ヒンジ機構によって開閉自在な状態で設けられている。本実施形態では、図3に示すように、第1蓋部32において奥側に位置する端部を持ち上げることで第1蓋部32が開く。
Further, as shown in FIGS. 1 and 3, the case unit 35 is attached with a lid (hereinafter, referred to as a first lid 32) for closing the upper end opening of the case unit 35. The first lid 32 constitutes a part of the housing upper wall 31a, and is provided so as to be openable and closable by a hinge mechanism. In the present embodiment, as shown in FIG. 3, the first lid 32 is opened by lifting the end portion of the first lid 32 located on the back side.
一方、第1蓋部32が閉じた状態では、ケースユニット35の上端開口が完全に塞がれる。かかる状態においてケースユニット35内に***物収容器20が入っている場合、第1蓋部32は、ケースユニット35内の***物収容器20を上方から覆うようになる。
On the other hand, when the first lid 32 is closed, the upper end opening of the case unit 35 is completely closed. When the excrement container 20 is contained in the case unit 35 in such a state, the first lid 32 covers the excrement container 20 in the case unit 35 from above.
また、第1蓋部32において手前側に位置する端部には、吸引ホース51の端部と係合する円筒状のコネクタ32aが形成されている。そして、コネクタ32aは、第1蓋部32の裏面側(すなわちケースユニット35)にも突出している。ケースユニット35に***物収容器20を収容した状態で、第1蓋部32を閉めると、コネクタ32aの下端部が***物収容器20の第1吸引口20bの内に嵌まり込む。
これにより、カップ部材10、吸引ホース51、コネクタ32a、第1吸引口20bを通じた***物Dの吸引路が形成される。 In addition, acylindrical connector 32 a that engages with the end of the suction hose 51 is formed at the end of the first lid 32 located on the front side. The connector 32 a also protrudes on the back surface side of the first lid 32 (that is, the case unit 35). With the waste container 20 housed in the case unit 35, when the first cover 32 is closed, the lower end of the connector 32a fits into the first suction port 20b of the waste container 20.
Thereby, the suction path of the excrement D which led thecup member 10, the suction hose 51, the connector 32a, and the first suction port 20b is formed.
これにより、カップ部材10、吸引ホース51、コネクタ32a、第1吸引口20bを通じた***物Dの吸引路が形成される。 In addition, a
Thereby, the suction path of the excrement D which led the
吸引部40は、ケースユニット35を減圧するためにケースユニット35内の空気を吸引すると共に、吸引した空気を、エア返送ホース53を通じてカップ部材10内に排出(返送)する機構である。具体的には、吸引部40は、ブロア41、ブロア41を収容するケースであるブロアケーシング43を備える。ブロアケーシング43は、空気の流入側として吸気口36を介してケースユニット35と接続されている。そして、ブロアケーシング43は、空気の循環用の流出側としてエア返送ホース53と接続され、空気の排気側として排気用ホース55と接続されている。
The suction unit 40 is a mechanism that sucks the air in the case unit 35 to decompress the case unit 35 and discharges (returns) the sucked air into the cup member 10 through the air return hose 53. Specifically, the suction unit 40 includes the blower 41 and a blower casing 43 which is a case for housing the blower 41. The blower casing 43 is connected to the case unit 35 via the air inlet 36 as an air inflow side. The blower casing 43 is connected to the air return hose 53 as an outflow side for circulating air, and is connected to an exhaust hose 55 as an air exhaust side.
ブロア41は、図6に示される制御電源70からの駆動電力の供給を受けるとともに、コントローラ80により動作を制御される。
例えば、ブロア41は、出力(換言すると、単位時間における吸気量)を調整することが可能である。一例としては、ブロア41は、強モード、中モード、弱モード等の複数の出力モードで動作可能とする。そして、吸引部40の出力モードは、***物の吸引、洗浄、洗浄前の冷水パージ、換気等の処理に応じて適宜設定される。 Theblower 41 receives the supply of drive power from the control power supply 70 shown in FIG.
For example, theblower 41 can adjust the output (in other words, the intake amount per unit time). As an example, the blower 41 can operate in a plurality of output modes such as a strong mode, a medium mode, and a weak mode. And the output mode of the suction part 40 is suitably set according to processes, such as suction of excrement, washing, cold water purge before washing, ventilation.
例えば、ブロア41は、出力(換言すると、単位時間における吸気量)を調整することが可能である。一例としては、ブロア41は、強モード、中モード、弱モード等の複数の出力モードで動作可能とする。そして、吸引部40の出力モードは、***物の吸引、洗浄、洗浄前の冷水パージ、換気等の処理に応じて適宜設定される。 The
For example, the
ブロア41が動作すると、ケースユニット35内の空気が吸気口36を通じて吸引部40に吸引される。なお、本実施形態において、吸引部40は、ケースユニット35内に***物収容器20が収められている状態にあるときに限り作動することとする。
When the blower 41 operates, the air in the case unit 35 is drawn into the suction unit 40 through the air inlet 36. In the present embodiment, the suction unit 40 operates only when the excrement container 20 is stored in the case unit 35.
また、吸引部40によって吸い込まれた空気の大部分は、エア返送ホース53を通じてカップ部材10に向けて返送される。より具体的に説明すると、エア返送ホース53は、ハウジング上壁31aを貫通してハウジング31内に進入している。また、図6に示すように、エア返送ホース53の端部(カップ部材10と接続している側とは反対の端部)は、ブロアケーシング43に繋ぎ込まれている。そして、ブロア41がケースユニット35内から吸引した空気をブロアケーシング43内で排出すると、その空気は、不図示の脱臭装置を経由した後、エア返送ホース53を通じてカップ部材10に返送されるようになる。
Further, most of the air sucked by the suction unit 40 is returned to the cup member 10 through the air return hose 53. More specifically, the air return hose 53 penetrates the housing upper wall 31 a and enters the housing 31. Further, as shown in FIG. 6, the end of the air return hose 53 (the end opposite to the side connected to the cup member 10) is connected to the blower casing 43. Then, when the blower 41 discharges the air sucked from the inside of the case unit 35 in the blower casing 43, the air passes through the deodorizing device (not shown) and is then returned to the cup member 10 through the air return hose 53. Become.
なお、本実施形態では、オムツP内に空気をスムーズに返送するために、ブロア41が吸引した空気の一部を、排気用ホース55及び脱臭装置56を通じて大気に放出している。これにより、カップ部材10内からの空気吸引量とカップ部材10への空気返送量との間に差が生じ、結果として、カップ部材10内へ空気が返送され易くなっている。
In the present embodiment, in order to smoothly return the air into the diaper P, part of the air sucked by the blower 41 is discharged to the atmosphere through the exhaust hose 55 and the deodorizing device 56. As a result, a difference occurs between the amount of air suctioned from the inside of the cup member 10 and the amount of air returned to the cup member 10, and as a result, air is easily returned into the cup member 10.
洗浄部60は、洗浄水供給部に相当し、カップ部材10に洗浄水を供給する機構である。本実施形態において、洗浄部60は、温水を生成し、生成した温水を洗浄水として供給する。洗浄部60は、図6に示されるように、カートリッジタンク61、温水タンク62及びポンプ63によって構成されている。
The cleaning unit 60 corresponds to a cleaning water supply unit, and is a mechanism for supplying cleaning water to the cup member 10. In the present embodiment, the cleaning unit 60 generates hot water and supplies the generated hot water as cleaning water. As shown in FIG. 6, the cleaning unit 60 includes a cartridge tank 61, a hot water tank 62, and a pump 63.
カートリッジタンク61は、洗浄水の原水を溜めておくタンクであり、装置本体30に対して着脱自在である。具体的に説明すると、ハウジング31内において、奥側の端部に位置する部分(すなわち、ケースユニット35とは反対側に位置する端部)には、箱状の容器であるタンクケーシング38が配置されている。タンクケーシング38は、その内部にカートリッジタンク61を収めることが可能である。また、タンクケーシング38は、上端に開口端を有する。すなわち、タンクケーシング38内のカートリッジタンク61は、タンクケーシング38の上端開口から取り出すことが可能である。なお、本実施形態において、タンクケーシング38は、カートリッジタンク61全体を収容するのに十分な深さを有している。
The cartridge tank 61 is a tank for storing raw water of washing water, and is removable from the apparatus main body 30. Specifically, in the housing 31, the tank casing 38, which is a box-like container, is disposed at a portion located at the end on the back side (that is, the end located on the opposite side to the case unit 35). It is done. The tank casing 38 can accommodate the cartridge tank 61 therein. Also, the tank casing 38 has an open end at the upper end. That is, the cartridge tank 61 in the tank casing 38 can be taken out from the upper end opening of the tank casing 38. In the present embodiment, the tank casing 38 has a depth sufficient to accommodate the entire cartridge tank 61.
また、図3に示すように、タンクケーシング38には、タンクケーシング38の上端開口を塞ぐ第2蓋部33が取り付けられている。第2蓋部33は、ハウジング上壁31aの一部として構成され、ヒンジ機構によって開閉自在な状態で設けられている。本実施形態では、図3に示すように、第2蓋部33において奥側に位置する端部を持ち上げることで第2蓋部33が開く。一方、第2蓋部33が閉じた状態では、タンクケーシング38の上端開口が完全に塞がれ、タンクケーシング38内のカートリッジタンク61の上方が第2蓋部33によって覆われるようになる。
Further, as shown in FIG. 3, a second lid 33 is attached to the tank casing 38 for closing the upper end opening of the tank casing 38. The second lid 33 is configured as a part of the housing upper wall 31a, and is provided in an openable / closable state by a hinge mechanism. In the present embodiment, as shown in FIG. 3, the second lid 33 is opened by lifting the end portion of the second lid 33 located on the back side. On the other hand, when the second cover 33 is closed, the upper end opening of the tank casing 38 is completely closed, and the upper side of the cartridge tank 61 in the tank casing 38 is covered by the second cover 33.
また、カートリッジタンク61の上部には水補給用のキャップが設けられており、下部には、タンクケーシング38内に収容された際に、タンクケーシング38に給水するための弁機構が設けられている。そして、タンクケーシング38に給水された水は、一度、ポンプ63に一旦受けられた後、ポンプ63から温水タンク62に送られる。
Further, a cap for supplying water is provided at the upper portion of the cartridge tank 61, and a valve mechanism for supplying water to the tank casing 38 when accommodated in the tank casing 38 is provided at the lower portion. . The water supplied to the tank casing 38 is once received by the pump 63 and then sent from the pump 63 to the hot water tank 62.
図6に示されるように、温水タンク62は、ポンプ63から受け取った水の温度を調整(具体的には加温)して温水を生成し、その温水を洗浄水として圧送する。そして、温水タンク62が有する洗浄水の吐出口には、洗浄水ホース52の端部(カップ部材10に接続されている側とは反対側の端部)が接続されている。これにより、温水タンク62から吐出された洗浄水は、洗浄水ホース52内を流れ、最終的にカップ部材10の洗浄水用ノズル16から噴出する。
As shown in FIG. 6, the hot water tank 62 adjusts (specifically, heats) the temperature of the water received from the pump 63 to generate hot water, and pumps the hot water as washing water. The end of the cleaning water hose 52 (the end opposite to the side connected to the cup member 10) is connected to the cleaning water discharge port of the warm water tank 62. Thereby, the wash water discharged from the warm water tank 62 flows in the wash water hose 52 and finally spouts from the wash water nozzle 16 of the cup member 10.
なお、本実施形態に係るポンプ63は、洗浄水の供給量を調整することが可能であり、例えば、***物Dの種類や洗浄開始時からの経過時間に応じて適宜供給量を変更することが可能である。
In addition, the pump 63 which concerns on this embodiment can adjust the supply amount of wash water, for example, changes a supply amount suitably according to the kind of excretion D, and the elapsed time from the time of washing | cleaning start. Is possible.
***物収容器20は、吸引ホース51を通じて吸引された***物D及び洗浄水を収容する中空容器である。本実施形態に係る***物収容器20は、例えば、合成樹脂製(一例としてABS、PP、PVC製)の容器であり、図3に示すように縦長直方体形状をなしている。***物収容器20は、通常、ケースユニット35内に収められた状態で利用される。また、ケースユニット35内に***物収容器20が収められている状態では、***物収容器20の内部空間と、ケースユニット35の内部スペース(具体的には、ケースユニット35内の、***物収容器20の外側に位置する空間)が連通している。
The waste container 20 is a hollow container for containing the waste D sucked through the suction hose 51 and washing water. The excrement container 20 according to the present embodiment is, for example, a container made of synthetic resin (as an example, made of ABS, PP, PVC), and as shown in FIG. The waste container 20 is normally used in a state of being stored in the case unit 35. Further, in a state in which the excrement container 20 is stored in the case unit 35, the excrement in the internal space of the excrement container 20 and the internal space of the case unit 35 (specifically, in the case unit 35) A space located outside the container 20 is in communication.
そして、ケースユニット35内に***物収容器20が収められている状態でブロア41が作動してケースユニット35内の空気を吸引すると、***物収容器20内の空気が第2吸引口20cから排出される。そして、***物収容器20内の空気がケースユニット35内の空気と共にブロア41によって吸引されるようになる。この結果、***物収容器20内が減圧される。
Then, when the blower 41 is operated and the air in the case unit 35 is sucked in a state in which the waste container 20 is stored in the case unit 35, the air in the waste container 20 is from the second suction port 20c. Exhausted. Then, the air in the waste container 20 is sucked by the blower 41 together with the air in the case unit 35. As a result, the inside of the waste container 20 is depressurized.
なお、図6に示すように、第2吸引口20cを覆う位置に除塵・脱臭フィルタ23が取り付けられている。除塵・脱臭フィルタ23は、サイズが第2吸引口20cよりも一回り大きいフィルタである。例えば、除塵・脱臭フィルタ23は、矩形シート状のフィルタとしてもよいし、形状は特に限定されない。***物収容器20内の空気が第2吸引口20cを通過する際、当該空気中の***物Dの成分を除塵・脱臭フィルタ23によって捕捉する。
As shown in FIG. 6, the dust removal / deodorization filter 23 is attached at a position covering the second suction port 20c. The dust removal / deodorization filter 23 is a filter that is one size larger than the second suction port 20 c. For example, the dust removal / deodorization filter 23 may be a rectangular sheet-like filter, and the shape is not particularly limited. When the air in the excrement container 20 passes through the second suction port 20c, the components of the excrement D in the air are captured by the dust removal / deodorization filter 23.
また、***物収容器20の上部において、第2吸引口20cが形成されている端部とは反対側の端部には略長円状の貫通孔(以下、第1吸引口20b)が設けられている。この第1吸引口20bは、***物Dや洗浄水を***物収容器20内に吸引するために形成されたものである。また、第1吸引口20bには、図6に示すように、吸引ホース51の端部(カップ部材10に接続されている側とは反対側の端部)が入り込む。
In the upper part of the excrement container 20, a substantially oval through hole (hereinafter referred to as a first suction port 20b) is provided at the end opposite to the end where the second suction port 20c is formed. It is done. The first suction port 20 b is formed to suck the excrement D and the washing water into the excrement container 20. Further, as shown in FIG. 6, the end of the suction hose 51 (the end opposite to the side connected to the cup member 10) enters the first suction port 20b.
また、本実施形態では、第1蓋部32の開閉操作により、***物収容器20に対する吸引ホース51及びコネクタ32aの挿抜を簡単に行うことが可能としている。また、このように構成することで、吸引ホース51の端部を***物収容器20から抜く際にホース端部に過度な力が掛かり難い。この結果、ホース端部を抜く際にホース端部に過度な力が掛かるために***物Dがホース端部の開口から飛び散ってケースユニット35内を汚してしまうような事態を回避することが可能となる。
Further, in the present embodiment, the opening and closing operation of the first lid 32 makes it possible to easily insert and remove the suction hose 51 and the connector 32 a with respect to the excrement container 20. In addition, with this configuration, when the end of the suction hose 51 is removed from the waste container 20, it is difficult for an excessive force to be applied to the end of the hose. As a result, it is possible to avoid a situation where the excrement D spatters from the opening of the hose end and contaminates the inside of the case unit 35 because an excessive force is applied to the hose end when removing the hose end. It becomes.
そして、第1蓋部32が閉じて吸引ホース51の端部が***物収容器20内に至った状態でブロア41がケースユニット35内の空気を吸引すると、***物収容器20内が減圧される。この際、カップ部材10上に***物Dが載っていると、***物Dが吸引されて吸引ホース51内を移動し***物収容器20内まで搬送される。また、洗浄部60からカップ部材10に洗浄水が供給されると、洗浄水も吸引ホース51を通じて***物収容器20内へ吸引される。
Then, when the blower 41 sucks the air in the case unit 35 in a state in which the first lid 32 is closed and the end of the suction hose 51 reaches the excrement container 20, the inside of the excrement container 20 is decompressed. Ru. At this time, if the excrement D is placed on the cup member 10, the excrement D is aspirated and moved in the suction hose 51 to be transported into the excrement container 20. Further, when the washing water is supplied from the washing unit 60 to the cup member 10, the washing water is also sucked into the waste container 20 through the suction hose 51.
具体的に説明すると、吸引された***物Dや洗浄水は、***物収容器20内に入り込んでいる吸引ホース51の端部の先端開口を通過すると、***物収容器20内で自重落下して同タンク内に溜まっていく。一方、***物Dや洗浄水と共に吸引された空気は、***物収容器20で***物Dや洗浄水から分離し、***物収容器20の第2吸引口20cからタンク外へ排出されてブロア41に吸い込まれる。
Specifically, when the excreted excrement D and the flush water pass through the tip opening of the end of the suction hose 51 entering the excrement storage container 20, they fall by their own weight in the excrement storage container 20. It will collect in the same tank. On the other hand, air sucked with the excrement D and the wash water is separated from the excrement D and the wash water in the excrement storage container 20, and is discharged from the second suction port 20c of the excrement storage container 20 to the outside of the tank to be a blower. Sucked in to 41.
***物収容器20は、その内部に所定量以上の***物や洗浄水が溜まった段階でケースユニット35から取り外される。すなわち、***物収容器20は、ケースユニット35に対して着脱可能である。より詳しく説明すると、閉じた状態の第1蓋部32を開くことにより、吸引ホース51の端部が***物収容器20から抜け、ケースユニット35の上端開口が開放される。その後、***物収容器20の取っ手20aを把持しながら***物収容器20を上方に持ち上げると、***物収容器20がケースユニット35から取り外すことができる。
The excrement container 20 is removed from the case unit 35 when excrement or washing water of a predetermined amount or more is accumulated therein. That is, the excrement container 20 can be attached to and detached from the case unit 35. More specifically, by opening the first lid 32 in the closed state, the end of the suction hose 51 is removed from the waste container 20, and the upper end opening of the case unit 35 is opened. Thereafter, the waste container 20 can be removed from the case unit 35 by lifting the waste container 20 while holding the handle 20 a of the waste container 20.
以上までに説明してきたように本実施形態では、***物Dや洗浄水と共に***物収容器20内に吸引された空気は、***物収容器20の内部空間(特に、内部空間中の上方部分)を移動し、第2吸引口20cを通じて***物収容器20の外に排出される。ここで、***物収容器20内を空気が移動する場合、一般的な配管やホース内を空気が移動する場合と比較して空気の移動速度(流速)が遅くなる。これにより、***物収容器20内で空気を***物Dや洗浄水から分離させることが一層容易になる。
As described above, in the present embodiment, the air sucked into the excrement container 20 together with the excrement D and the washing water is the internal space of the excrement container 20 (in particular, the upper portion in the internal space) ) And is discharged out of the waste container 20 through the second suction port 20c. Here, when the air moves in the waste container 20, the moving speed (flow velocity) of the air is slower than in the case where the air moves in a general pipe or hose. This makes it easier to separate the air from the excrement D and the wash water in the excrement container 20.
また、第2吸引口20cから***物収容器20の外に出た空気は、ケースユニット35内を移動して吸気口36に向かう。やがて、空気は、ケースユニット35内で吸引フィルタ37を通過した後、吸気口36を通じてケースユニット35内からブロアケーシング43内に移り、ブロアケーシング43内でブロア41に吸い込まれる。このように本実施形態では、***物収容器20の第2吸引口20cとケースユニット35の吸気口36とは、これらの間にケースユニット35内の一部の空間が介在していることで、互いに隔てられている。つまり、本実施形態では、第2吸引口20cと吸気口36とが直接連結されてなく、第2吸引口20cと吸気口36との間を連結する配管等も設けられていない。
Further, the air which has flowed out of the excrement container 20 from the second suction port 20 c moves in the case unit 35 and is directed to the air inlet 36. Eventually, after passing through the suction filter 37 in the case unit 35, the air moves from the inside of the case unit 35 to the inside of the blower casing 43 through the air inlet 36 and is sucked into the blower 41 in the blower casing 43. As described above, in the present embodiment, the second suction port 20c of the excrement container 20 and the air intake port 36 of the case unit 35 have a part of the space in the case unit 35 between them. , Are separated from each other. That is, in the present embodiment, the second suction port 20c and the suction port 36 are not directly connected, and a pipe or the like connecting the second suction port 20c and the suction port 36 is not provided.
以上のように第2吸引口20cと吸気口36との間にスペースが設けられていることで、第2吸引口20cから***物収容器20の外に出た空気は、上記のスペースに一旦放出されてから吸気口36を通じてブロア41に吸引されるようになる。これにより、ブロア41が***物収容器20内の空気を吸気する際に、水分(***物Dや洗浄水に由来するミスト水)や***物D中の菌等が空気と共に吸引されてブロア41やエア返送ホース53等が汚染されてしまうのを抑制することが可能となる。
As described above, since the space is provided between the second suction port 20c and the intake port 36, the air that has flowed out of the excrement container 20 from the second suction port 20c is temporarily stored in the above space. After being discharged, the air is drawn into the blower 41 through the air inlet 36. Thereby, when the blower 41 sucks in air in the excrement container 20, water (mist water derived from the excrement D and wash water), bacteria in the excrement D, etc. are aspirated together with the air, and the blower 41 is removed. It is possible to suppress the contamination of the air return hose 53 and the like.
なお、上述したように、***物収容器20の外に出た空気は、ケースユニット35内に一旦放出されるので、空気が仮に水分や菌等が混入した状態で***物収容器20の外に出たとしても、水分や菌等をケースユニット35内に収めておくことが可能となる。つまり、本実施形態では、汚染箇所の拡大を抑えることが可能である。
Note that, as described above, the air that has come out of the excrement container 20 is temporarily released into the case unit 35, so that the air may be temporarily mixed with water, bacteria, and the like, and the outside of the excrement container 20. Even if it comes out, it is possible to store water, bacteria, etc. in the case unit 35. That is, in the present embodiment, it is possible to suppress the spread of the contaminated portion.
また、本実施形態では、***物吸引装置1の循環経路をコンパクトなものとすることで、装置内を空気が流れるときの圧損も小さく抑えられている。これにより、ブロア41が吸気する際の負荷が小さくなるので、ブロア41の出力(消費電力)の大きさも抑えられるようになる。さらに、ブロア41の出力が抑えられることで、ブロア41の作動熱を取り除くための付属機器(例えば、ラジエータ)等も不要となる。
Further, in the present embodiment, by making the circulation path of the excrement suction device 1 compact, the pressure loss when air flows in the device is also suppressed to a small value. As a result, since the load when the blower 41 takes in air is reduced, the magnitude of the output (power consumption) of the blower 41 can also be suppressed. Furthermore, by suppressing the output of the blower 41, an accessory device (for example, a radiator) or the like for removing the operation heat of the blower 41 is not necessary.

第1判定部84は、電極部15の検出結果に基づいて、カップ部材10の中における***物の有無を判定する機能である。
例えば、第1判定部84は、電極部15の第1電極ペア15a、第2電極ペア15bからなる複数の電極ペアのうち少なくともいずれかの検出値が所定条件を満足する場合に、カップ部材10の受け面11aの上に***物が有ると判定する。
ここで、上記の「検出値」は例えば、電流値、インピーダンス(抵抗値)、電気伝導率、アドミタンス等を用いてよい。また、上記の「所定条件」は電極ペアが導体(***物)により接続されたことを「検出値」により検出するための条件である。換言すれば、電極ペアの上に***物等の導体が接している場合には、電極ペアの「検出値」が「所定条件」を満足することとなる。一方で、電極ペアの上に***物等の導体が接していない場合には、「検出値」が「所定条件」を満足しないこととなる。
例えば、上記の「検出値」に電流値を用いた場合には、いずれかの電極ペアで検出される電流値が所定値以上である場合に、第1判定部84は、カップ部材10の受け面11aの上に***物が有ると判定する。一方で、いずれの電極ペアで検出される電流値も所定値未満である場合に、第1判定部84は、カップ部材10の受け面11aの上に***物が無いと判定する。 Thefirst determination unit 84 has a function of determining the presence or absence of excrement in the cup member 10 based on the detection result of the electrode unit 15.
For example, when the detection value of at least one of the plurality of electrode pairs consisting of thefirst electrode pair 15a and the second electrode pair 15b of the electrode unit 15 satisfies the predetermined condition, the first determination unit 84 determines the cup member 10 It is determined that there is excrement on the receiving surface 11a of the
Here, for example, a current value, an impedance (resistance value), an electrical conductivity, an admittance, or the like may be used as the above-mentioned “detection value”. Moreover, said "predetermined conditions" are conditions for detecting that the electrode pair was connected by the conductor (excrement) by a "detection value." In other words, when a conductor such as excrement is in contact with the electrode pair, the “detected value” of the electrode pair satisfies the “predetermined condition”. On the other hand, when a conductor such as excrement is not in contact with the electrode pair, the "detection value" does not satisfy the "predetermined condition".
For example, in the case where a current value is used as the above “detection value”, thefirst determination unit 84 receives the cup member 10 when the current value detected by any of the electrode pairs is equal to or more than a predetermined value. It is determined that there is excrement on the surface 11a. On the other hand, when the current value detected by any electrode pair is less than the predetermined value, the first determination unit 84 determines that there is no excrement on the receiving surface 11 a of the cup member 10.
例えば、第1判定部84は、電極部15の第1電極ペア15a、第2電極ペア15bからなる複数の電極ペアのうち少なくともいずれかの検出値が所定条件を満足する場合に、カップ部材10の受け面11aの上に***物が有ると判定する。
ここで、上記の「検出値」は例えば、電流値、インピーダンス(抵抗値)、電気伝導率、アドミタンス等を用いてよい。また、上記の「所定条件」は電極ペアが導体(***物)により接続されたことを「検出値」により検出するための条件である。換言すれば、電極ペアの上に***物等の導体が接している場合には、電極ペアの「検出値」が「所定条件」を満足することとなる。一方で、電極ペアの上に***物等の導体が接していない場合には、「検出値」が「所定条件」を満足しないこととなる。
例えば、上記の「検出値」に電流値を用いた場合には、いずれかの電極ペアで検出される電流値が所定値以上である場合に、第1判定部84は、カップ部材10の受け面11aの上に***物が有ると判定する。一方で、いずれの電極ペアで検出される電流値も所定値未満である場合に、第1判定部84は、カップ部材10の受け面11aの上に***物が無いと判定する。 The

For example, in the case where a current value is used as the above “detection value”, the
第1判定部84は、主にコントローラ80のプロセッサ81、記憶装置82及び入出力インターフェース83により以下のように実現される。
The first determination unit 84 is mainly realized by the processor 81, the storage device 82, and the input / output interface 83 of the controller 80 as follows.
コントローラ80のプロセッサ81は、入出力インターフェース83を介して電極部15の各電極ペアに流れる電流値のデータを取得する。具体的には、プロセッサ81は、入出力インターフェース83を介して、電極部15の第1電極ペア15a、第2電極ペア15bのそれぞれに流れる電流値のデータを取得する。そして、電極ペアのプラス極とマイナス極が***物を導体として接続されると、微弱な電流が流れる。
The processor 81 of the controller 80 acquires data of the current value flowing to each electrode pair of the electrode unit 15 through the input / output interface 83. Specifically, the processor 81 acquires data of current values flowing in the first electrode pair 15a and the second electrode pair 15b of the electrode unit 15 through the input / output interface 83. Then, when the positive and negative electrodes of the electrode pair are connected as wastes as conductors, a weak current flows.
なお、電極ペアのプラス極とマイナス極が洗浄水を導体として接続された場合にも電流が流れるが、***物は洗浄水よりも塩度が高い(電解質が多い)ため、***物を導体として接続された場合の方が、電気伝導率が高くなり、その結果電流値が大きくなる。そこで、電極ペアに流れる電流値を適切な閾値と比較することにより、電極ペアに接しているものが***物であるか洗浄水であるかを区別可能である。
具体的には、プロセッサ81は、いずれかの電極ペアに流れる電流値が所定の閾値以上である場合に、カップ部材10の中に***物があると判定する。なお、上記の所定の閾値は、記憶装置82に予め記憶されたデータであり、実験結果等に基づいて適宜設定されることとしてよい。 Although current flows even when the positive and negative electrodes of the electrode pair are connected with washing water as a conductor, the excrement is higher in salinity than the washing water (there are more electrolytes). In the case of connection, the electrical conductivity is higher, and as a result, the current value is larger. Therefore, by comparing the current value flowing in the electrode pair with an appropriate threshold value, it is possible to distinguish whether the object in contact with the electrode pair is excrement or washing water.
Specifically, theprocessor 81 determines that there is excrement in the cup member 10 when the current value flowing to any of the electrode pairs is equal to or more than a predetermined threshold value. Note that the predetermined threshold is data stored in advance in the storage device 82, and may be appropriately set based on experimental results and the like.

Therefore, by comparing the current value flowing in the electrode pair with an appropriate threshold value, it is possible to distinguish whether the object in contact with the electrode pair is excrement or washing water.
Specifically, the
また、上記の例では、電極部15の各電極ペアに、電極ペアのいずれかに流れる電流値が所定の閾値以上である場合に検出信号をコントローラ80に出力する検出回路を接続してもよい。この場合には、プロセッサ81は、検出回路からの検出信号を受け取った場合にはカップ部材10の中に排出物が検出されたと判定する。
Further, in the above example, a detection circuit that outputs a detection signal to the controller 80 may be connected to each electrode pair of the electrode unit 15 when the current value flowing to any of the electrode pairs is equal to or greater than a predetermined threshold. . In this case, when the processor 81 receives a detection signal from the detection circuit, the processor 81 determines that the discharge has been detected in the cup member 10.
なお、上記の例では、電極部15から検出される電流値に基づいて判定を行うこととしたが、電極部15の各電極ペアの導電率に応じて変化するデータであれば、電流値に限られず、他のデータ(抵抗値、電気伝導率等)を用いてもよい。
In the above example, the determination is made based on the current value detected from the electrode unit 15. However, if the data changes according to the conductivity of each electrode pair of the electrode unit 15, the current value is used. The data is not limited, and other data (resistance value, electrical conductivity, etc.) may be used.
また、第1判定部84は、第1電極ペア15aのプラス極(又はマイナス極)と、いずれかの第2電極ペア15bのマイナス極(又はプラス極)との間の導電率の変化を検出して、***物の有無を判定してもよい。
また、第1判定部84は、1つの第2電極ペア15bのプラス極(又はマイナス極)と、隣接する第2電極ペア15bのマイナス極(又はプラス極)との間の導電率の変化を検出して、***物の有無を判定してもよい。
こうすることで、カップ部材10の中の広い範囲で***物を検知することが可能となる。 Further, thefirst determination unit 84 detects a change in conductivity between the plus pole (or minus pole) of the first electrode pair 15a and the minus pole (or plus pole) of any second electrode pair 15b. Then, the presence or absence of excrement may be determined.
In addition, thefirst determination unit 84 changes the conductivity between the plus pole (or minus pole) of one second electrode pair 15b and the minus pole (or plus pole) of the adjacent second electrode pair 15b. It may be detected to determine the presence or absence of excrement.
By this, it is possible to detect excrement in a wide range in thecup member 10.
また、第1判定部84は、1つの第2電極ペア15bのプラス極(又はマイナス極)と、隣接する第2電極ペア15bのマイナス極(又はプラス極)との間の導電率の変化を検出して、***物の有無を判定してもよい。
こうすることで、カップ部材10の中の広い範囲で***物を検知することが可能となる。 Further, the
In addition, the
By this, it is possible to detect excrement in a wide range in the
洗浄前処理部85は、第1判定部84によりカップ部材10に***物が有ると判定された場合に、吸引部40に吸引を実行させる機能である。
例えば、洗浄前処理部85は、第1判定部84によりカップ部材10に***物が有ると判定された場合に、吸引部40による吸引とともに、洗浄部60により洗浄水をカップ部材10に供給させる。
また、洗浄前処理部85は、洗浄部60による洗浄水の供給に当たり、ポンプ63の出力を、通常の洗浄時におけるモード(第1の出力モード)よりも低出力のモード(第2の出力モード)に設定して、ポンプ63を動作させることとしてよい。 The cleaningpretreatment unit 85 is a function that causes the suction unit 40 to perform suction when the first determination unit 84 determines that the cup member 10 has excrement.
For example, when thefirst determination unit 84 determines that the cup member 10 has excrement, the pre-wash processing unit 85 causes the washing unit 60 to supply the washing water to the cup member 10 along with the suction by the suction unit 40. .
In addition, when thecleaning unit 60 supplies the cleaning water by the cleaning unit 60, the output of the pump 63 is set to a mode (second output mode) that is lower than the mode (first output mode) at the time of normal cleaning. And the pump 63 may be operated.

For example, when the
In addition, when the
洗浄前処理部85は、主にコントローラ80のプロセッサ81、記憶装置82及び入出力インターフェース83により以下のように実現される。
The cleaning pretreatment unit 85 is mainly realized by the processor 81 of the controller 80, the storage device 82, and the input / output interface 83 as follows.
コントローラ80のプロセッサ81は、第1判定部84によりカップ部材10内に***物が有ると判定した場合に、ブロア41を強モードで動作させるための強吸引信号を、入出力インターフェース83を介してブロア41に伝送する。そして、ブロア41は、上記の強吸引信号の受信に応じて、強モードでの吸引を開始する。これにより、カップ部材10内の***物が吸引ホース51を通じて***物収容器20側に吸引される。
When the processor 81 of the controller 80 determines that there is excrement in the cup member 10 by the first determination unit 84, a strong suction signal for operating the blower 41 in the strong mode is transmitted through the input / output interface 83. Transmit to blower 41. Then, the blower 41 starts suction in the strong mode in response to the reception of the above-described strong suction signal. Thereby, the excrement in the cup member 10 is aspirated to the excrement container 20 side through the suction hose 51.
次に、プロセッサ81は、上記の強モード動作信号の送出時点から所定の第1時間が経過すると、ポンプ63を弱モードで動作させるための弱噴出信号を、入出力インターフェース83を介してポンプ63に伝送する。そして、ポンプ63は、上記の弱噴出信号の受信に応じて、弱モードでの温水タンク62からの送水を開始する。これにより、洗浄水用ノズル16からはカップ部材10の内部に向けて洗浄水が弱モードで噴出する。
なお、ポンプ63から洗浄水が送られている間にも、ブロア41は強モードでの吸引を継続している。このように、洗浄水用ノズル16からは弱い勢いで洗浄水を噴出させ、かつブロア41により強モードで吸引を行うようにする。これにより、洗浄水が***物吸引口13側に引き込まれるため、吸引ホース51に溜まった加温されていない洗浄水が***部位Eに当たることを抑制できる。 Next, theprocessor 81 causes the pump 63 to operate, via the input / output interface 83, a weak ejection signal for operating the pump 63 in the weak mode when a predetermined first time has elapsed from the point of time when the strong mode operation signal is sent. Transmit to Then, the pump 63 starts water supply from the hot water tank 62 in the weak mode in response to the reception of the above-mentioned weak ejection signal. As a result, the washing water is jetted from the washing water nozzle 16 toward the inside of the cup member 10 in the weak mode.
In addition, while the washing water is sent from thepump 63, the blower 41 continues the suction in the strong mode. As described above, the washing water is jetted from the washing water nozzle 16 with a weak force, and suction is performed by the blower 41 in the strong mode. As a result, since the flush water is drawn to the side of the excrement suction port 13, the unheated flush water accumulated in the suction hose 51 can be prevented from hitting the excretory site E.
なお、ポンプ63から洗浄水が送られている間にも、ブロア41は強モードでの吸引を継続している。このように、洗浄水用ノズル16からは弱い勢いで洗浄水を噴出させ、かつブロア41により強モードで吸引を行うようにする。これにより、洗浄水が***物吸引口13側に引き込まれるため、吸引ホース51に溜まった加温されていない洗浄水が***部位Eに当たることを抑制できる。 Next, the
In addition, while the washing water is sent from the
上記の処理により、洗浄前に、温水タンク62とカップ部材10の間の洗浄水ホース52に溜まった冷水をパージ(抜く)ことができる。なお、以下においては、ブロア41とポンプ63を連動して動作させることで、洗浄前の洗浄水ホース52に溜まった冷水を抜く処理を、冷水パージ処理と称する。
By the above-described process, it is possible to purge (remove) the cold water accumulated in the washing water hose 52 between the hot water tank 62 and the cup member 10 before washing. In the following, the process of removing the cold water accumulated in the wash water hose 52 before washing by operating the blower 41 and the pump 63 in conjunction with each other is referred to as a cold water purge process.
そして、プロセッサ81は、ポンプ63を弱モードで動作させてから、所定の第2時間が経過すると、入出力インターフェース83を介して、ブロア41とポンプ63のそれぞれに対して動作停止信号を伝送して、ブロア41とポンプ63の動作を停止させる。なお、上記の第2時間は、例えば洗浄水ホース52内に溜まった洗浄水を完全に入れ換えるために十分な時間とする。
Then, the processor 81 transmits an operation stop signal to each of the blower 41 and the pump 63 via the input / output interface 83 when a predetermined second time elapses after operating the pump 63 in the weak mode. The operation of the blower 41 and the pump 63 is stopped. The above second time is, for example, a time sufficient to completely replace the washing water accumulated in the washing water hose 52.
第2判定部86は、洗浄前処理部85による吸引の実行後に、第1判定部84により***物が有ると判定された場合に***物が便と判定し、第1判定部84により***物が無いと判定された場合に***物が尿と判定する機能である。
The second determination unit 86 determines that the excrement is feces when the first determination unit 84 determines that there is excrement after the suction pre-treatment unit 85 executes the aspiration, and the first determination unit 84 determines the excrement It is a function to determine excrement as urine when it is determined that there is no
第2判定部86が上記のように判定するのは、以下の理由による。
まず、***物が尿である場合には、洗浄前処理部85による吸引及び冷水パージ処理によって、尿は吸引ホース51側に吸引され、吸引後には第1判定部84による***物の検出が行われなくなると考えられるためである。
一方で、***物が便である場合には、便は尿に比べて重いため、洗浄前処理部85による吸引及び冷水パージ処理によっては、全ての便が吸引ホース51側に吸引されず、吸引後においても第1判定部84による***物の検出が行われると考えられるためである。 Thesecond determination unit 86 determines as described above for the following reasons.
First, when the excrement is urine, the urine is aspirated toward theaspiration hose 51 by suction and cold water purge processing by the cleaning pretreatment unit 85, and after suction, the first determination unit 84 detects the excrement It is believed that they will not be
On the other hand, when the excrement is stool, the stool is heavier than urine, so depending on the suction by thepre-wash processing unit 85 and the cold water purge processing, not all the stool is suctioned to the suction hose 51 side, This is because it is considered that detection of excrement by the first determination unit 84 will be performed later as well.
まず、***物が尿である場合には、洗浄前処理部85による吸引及び冷水パージ処理によって、尿は吸引ホース51側に吸引され、吸引後には第1判定部84による***物の検出が行われなくなると考えられるためである。

第2判定部86は、主にコントローラ80のプロセッサ81、記憶装置82及び入出力インターフェース83により以下のように実現される。
The second determination unit 86 is mainly realized by the processor 81, the storage device 82, and the input / output interface 83 of the controller 80 as follows.
コントローラ80のプロセッサ81は、洗浄前処理部85による冷水パージ処理の実行後に、電極部15の各電極ペアに流れる電流値を、入出力インターフェース83を介して取得する。そして、プロセッサ81は、電極部15のいずれかの電極ペアに流れる電流値が所定の閾値以上である場合に、カップ部材10の中に***された***物が便(大便)であると判定する。
一方、プロセッサ81は、電極部15のいずれの電極ペアに流れる電流値が所定の閾値未満である場合に、カップ部材10の中に***された***物が尿であると判定する。 Theprocessor 81 of the controller 80 acquires the current value flowing through each electrode pair of the electrode unit 15 through the input / output interface 83 after the cold water purge process by the cleaning pretreatment unit 85 is performed. Then, the processor 81 determines that the excrement excreted in the cup member 10 is feces (feces) when the current value flowing to any of the electrode pairs of the electrode unit 15 is equal to or greater than a predetermined threshold value. .
On the other hand, theprocessor 81 determines that the excrement excreted in the cup member 10 is urine when the current value flowing to any of the electrode pairs of the electrode unit 15 is less than a predetermined threshold.

洗浄処理部87は、第2判定部86による判定結果に応じたモードで洗浄部60を動作させて、***部位の洗浄を実行する機能である。
洗浄処理部87は、洗浄部60による洗浄水の供給に当たり、ポンプ63の出力を、洗浄前処理部85による冷水パージ処理における出力モード(第2の出力モード)よりも強いモード(第1の出力モード)に設定して、ポンプ63を動作させることとしてよい。 Thewashing processing unit 87 is a function of operating the washing unit 60 in a mode according to the determination result by the second determination unit 86 to wash the excretory part.
When thewashing processing unit 87 supplies the washing water by the washing unit 60, the output of the pump 63 is stronger than the output mode (second output mode) in the cold water purge processing by the washing pretreatment unit 85 (first output) And the pump 63 may be operated.
洗浄処理部87は、洗浄部60による洗浄水の供給に当たり、ポンプ63の出力を、洗浄前処理部85による冷水パージ処理における出力モード(第2の出力モード)よりも強いモード(第1の出力モード)に設定して、ポンプ63を動作させることとしてよい。 The

洗浄処理部87は、主にコントローラ80のプロセッサ81、記憶装置82及び入出力インターフェース83により以下のように実現される。
The cleaning processing unit 87 is mainly realized by the processor 81 of the controller 80, the storage device 82 and the input / output interface 83 as follows.
コントローラ80のプロセッサ81は、第2判定部86により***物が便(大便)と判定した場合には、便モードによる洗浄処理を実行する。
具体的には、プロセッサ81は、ブロア41による送風(吸引)をA秒(例えば3秒)、ポンプ63による噴水をB秒(例えば5秒)実行する便モード基本洗浄パターンをC回(例えば5回)実行することで、上記の便モードによる洗浄処理を実行する。
なお、プロセッサ81は、洗浄処理の実行中に、操作部34を介して停止信号が入力された場合には、上記の便モードによる洗浄処理を停止することとしてよい。 When thesecond determination unit 86 determines that the excrement is stool (feces), the processor 81 of the controller 80 executes the cleaning process in the stool mode.
Specifically, theprocessor 81 executes the blow mode basic suction pattern C times (e.g. 5 times) in which the blower 41 performs the air blowing (suction) for A seconds (e.g. 3 seconds) and the fountain by the pump 63 B seconds (e.g. 5 seconds). The above-described stool mode washing process is performed by executing the above operation.
When the stop signal is input through theoperation unit 34 while the cleaning process is being performed, the processor 81 may stop the cleaning process in the above-described stool mode.
具体的には、プロセッサ81は、ブロア41による送風(吸引)をA秒(例えば3秒)、ポンプ63による噴水をB秒(例えば5秒)実行する便モード基本洗浄パターンをC回(例えば5回)実行することで、上記の便モードによる洗浄処理を実行する。
なお、プロセッサ81は、洗浄処理の実行中に、操作部34を介して停止信号が入力された場合には、上記の便モードによる洗浄処理を停止することとしてよい。 When the
Specifically, the
When the stop signal is input through the
また、プロセッサ81は、第2判定部86により***物が尿と判定した場合には、尿モードによる洗浄処理を実行する。
具体的には、プロセッサ81は、ブロア41による送風(吸引)をD秒(例えば3秒)、ポンプ63による噴水をE秒(例えば3秒)実行する尿モード基本洗浄パターンをF回(例えば1回)実行することで、上記の尿モードによる洗浄処理を実行する。
なお、プロセッサ81は、洗浄処理の実行中に、操作部34を介して停止信号が入力された場合には、上記の尿モードによる洗浄処理を停止することとしてよい。 In addition, when thesecond determination unit 86 determines that the excrement is urine, the processor 81 executes the cleaning process in the urine mode.
Specifically, theprocessor 81 executes the air mode basic cleaning pattern F times (e.g., 1) in which the blower 41 performs air blowing (suction) for D seconds (e.g. 3 seconds) and fountains by the pump 63 for E seconds (e.g. 3 seconds). The above-mentioned urine mode cleaning process is performed by executing the above operation.
Theprocessor 81 may stop the washing process in the above-mentioned urine mode when the stop signal is input through the operation unit 34 while the washing process is being performed.
具体的には、プロセッサ81は、ブロア41による送風(吸引)をD秒(例えば3秒)、ポンプ63による噴水をE秒(例えば3秒)実行する尿モード基本洗浄パターンをF回(例えば1回)実行することで、上記の尿モードによる洗浄処理を実行する。
なお、プロセッサ81は、洗浄処理の実行中に、操作部34を介して停止信号が入力された場合には、上記の尿モードによる洗浄処理を停止することとしてよい。 In addition, when the

The
なお、洗浄処理時におけるブロア41の出力は、例えば冷水パージにおける出力以上としてよい。例えば、大便の洗浄時のブロア41の出力をA、尿の洗浄時Bのブロア41の出力をB、冷水パージ実行時のブロア41の出力をCとすると、A≧B≧Cとしてよい。具体的には、ブロア41の出力が強、中、弱の三段階であり、大便の洗浄時のブロア41の出力を強、小便の洗浄処理時のブロア41の出力を中、冷水パージ時のブロア41の出力を弱に設定することとしてよい。
The output of the blower 41 during the cleaning process may be, for example, equal to or higher than the output in the cold water purge. For example, assuming that the output of the blower 41 at the time of washing of stool is A, the output of the blower 41 at the time of cleaning of urine B is B, and the output of the blower 41 at the time of cold water purge execution is C, ABB ≧ C. Specifically, the output of the blower 41 is three stages of strong, medium and weak, the output of the blower 41 is strong when the stool is washed, the output of the blower 41 is the middle when the urine is washed, and the cold water is purged The output of the blower 41 may be set weak.
また、洗浄処理時におけるポンプ63の出力は、例えば冷水パージにおける出力よりも強い設定を用いることとしてよい。具体的には、ポンプ63の出力が強、中、弱の三段階であり、冷水パージにおけるポンプ63の出力を弱とすると、洗浄処理時におけるポンプ63の出力は、例えば中又は強に設定することとしてよい。また、ポンプ63の出力は、便モードと尿モードとにおいて変更してもよく、例えば便モードのポンプ63の出力を、尿モードのポンプ63の出力よりも強くしてもよい。
Also, the output of the pump 63 at the time of the cleaning process may use, for example, a setting that is stronger than the output of the cold water purge. Specifically, when the output of the pump 63 is three stages of strong, medium and weak, and the output of the pump 63 in the cold water purge is weak, the output of the pump 63 at the time of cleaning processing is set to medium or strong, for example It is good. Further, the output of the pump 63 may be changed in the stool mode and the urine mode. For example, the output of the pump 63 in the stool mode may be stronger than the output of the pump 63 in the urine mode.
また、尿モードによる洗浄処理において、前回の尿モードの洗浄処理からの経過時間が所定の頻尿判定時間以下である場合には、ポンプ63による洗浄水の噴射は行わずに、ブロア41による送風(吸引)のみを行うようにしてもよい。
Further, in the cleaning process in the urine mode, when the elapsed time from the previous cleaning process in the urine mode is equal to or less than the predetermined frequent urination determination time, blowing of the cleaning water by the pump 63 is not performed. Only (suction) may be performed.

The processes shown in FIGS. 9 and 10 are mainly executed by the
図9に示されるように、コントローラ80のプロセッサ81は、電極部15により、カップ部材10内に***物が検出されたか否かを判定する(S1)。例えば、S1の処理は第1判定部84により実行される第1判定工程である。
As shown in FIG. 9, the processor 81 of the controller 80 determines whether or not excrement is detected in the cup member 10 by the electrode unit 15 (S1). For example, the process of S1 is a first determination step performed by the first determination unit 84.
S1で***物が検出されていない場合には(S1:No)、S1の処理を継続する。
次に、S1で***物が検出された場合には(S1:Yes)、コントローラ80のプロセッサ81は、冷水パージ処理を実行する(S2)。
ここで、冷水パージ処理の流れについては図10のフロー図を参照しながら説明する。なお、図10に示す冷水パージ処理(洗浄前処理工程)は、S1で***物が検出されてから所定時間後に開始することとしてよい。 If no excrement is detected in S1 (S1: No), the process of S1 is continued.
Next, when excrement is detected in S1 (S1: Yes), theprocessor 81 of the controller 80 executes cold water purge processing (S2).
Here, the flow of the cold water purge process will be described with reference to the flow diagram of FIG. The cold water purge process (pre-wash process step) shown in FIG. 10 may be started a predetermined time after the excrement is detected in S1.

Next, when excrement is detected in S1 (S1: Yes), the
Here, the flow of the cold water purge process will be described with reference to the flow diagram of FIG. The cold water purge process (pre-wash process step) shown in FIG. 10 may be started a predetermined time after the excrement is detected in S1.
図10に示されるように、コントローラ80のプロセッサ81は、強モードでブロア41を動作させて、ブロア41によるカップ部材10内の***物の吸引を実行する(S11)。
なお、ブロア41による吸引は、***物の吸引処理の最後まで継続する。また、ブロア41の出力は、***物の吸引処理の最中において変更可能である。 As shown in FIG. 10, theprocessor 81 of the controller 80 operates the blower 41 in the strong mode to perform suction of waste in the cup member 10 by the blower 41 (S11).
The suction by theblower 41 is continued until the end of the suction processing of the excrement. In addition, the output of the blower 41 can be changed during the process of suctioning excrement.
なお、ブロア41による吸引は、***物の吸引処理の最後まで継続する。また、ブロア41の出力は、***物の吸引処理の最中において変更可能である。 As shown in FIG. 10, the
The suction by the
そして、S11におけるブロア41による吸引実行の開始から第1所定時間が経過まで待機し(S12:No)、第1所定時間が経過すると(S12:Yes)、プロセッサ81は、弱モードでポンプ63を動作させる。これにより、カップ部材10に洗浄水の噴出が行われる(S13)。
なお、ポンプ63による洗浄水のカップ部材10への供給は、後述するS15の処理まで継続する。 Then, theprocessor 81 waits for the first predetermined time to elapse from the start of suction execution by the blower 41 in S11 (S12: No), and when the first predetermined time elapses (S12: Yes), the processor 81 sets the pump 63 in the weak mode. Make it work. As a result, the washing water is jetted to the cup member 10 (S13).
The supply of washing water to thecup member 10 by the pump 63 is continued until the process of S15 described later.
なお、ポンプ63による洗浄水のカップ部材10への供給は、後述するS15の処理まで継続する。 Then, the
The supply of washing water to the
そして、S13におけるポンプ63による洗浄水のカップ部材10への供給の開始から第2所定時間が経過するまで待機し(S14:No)、第2所定時間が経過すると(S14:Yes)、プロセッサ81は、ポンプ63の動作を停止して(S15)、冷水パージ処理を終える。
And it waits until the 2nd predetermined time passes from the start of supply of the washing water to cup member 10 by pump 63 in S13 (S14: No), and when the 2nd predetermined time passes (S14: Yes), processor 81 The operation of the pump 63 is stopped (S15) to complete the cold water purge process.
ここで再び図9に戻り説明を続ける。図9に示されるように、冷水パージ処理を終えると、コントローラ80のプロセッサ81は、再び電極部15により、カップ部材10内に***物が検出されたか否かを判定する(S3)。例えば、S3の処理は第1判定部84により実行される第1判定工程である。
Here, returning to FIG. 9 again, the explanation will be continued. As shown in FIG. 9, when the cold water purge process is finished, the processor 81 of the controller 80 determines again whether or not the excrement is detected in the cup member 10 by the electrode unit 15 (S3). For example, the process of S3 is a first determination step performed by the first determination unit 84.
そして、S3においてカップ部材10内に***物が検出された場合には(S3:Yes)、コントローラ80のプロセッサ81は、S1で検出した***物は便(大便)と判定する(S4)。例えば、S3、S4の処理は第2判定部86により実行される第2判定工程である。
この場合、コントローラ80のプロセッサ81は、便モードによる洗浄処理を実行する(S5)。なお、便モードによる洗浄処理は、洗浄処理部87により実行される。
また、洗浄処理を実行後に、適宜、換気処理が実行される。具体的には、換気処理は、例えば、S1において***物を検出していない間に(S1:No)、ブロア41のみを所定時間動作させる処理を繰り返すことにより実行される。この換気処理におけるブロア41の出力は、弱モードに設定される。なお、換気処理は、操作部34で受け付けた操作に応じて、途中で停止してもよいし、ユーザの設定により停止するようにしてもよい。 Then, when excrement is detected in thecup member 10 in S3 (S3: Yes), the processor 81 of the controller 80 determines that the excrement detected in S1 is stool (stool) (S4). For example, the processes of S3 and S4 are a second determination step performed by the second determination unit 86.
In this case, theprocessor 81 of the controller 80 executes the washing process in the stool mode (S5). In addition, the washing process according to the stool mode is performed by the washing processing unit 87.
In addition, after the cleaning process is performed, the ventilation process is appropriately performed. Specifically, the ventilation process is performed, for example, by repeating the process of operating only theblower 41 for a predetermined time while the excrement is not detected in S1 (S1: No). The output of the blower 41 in this ventilation process is set to the weak mode. The ventilation process may be stopped halfway according to the operation received by the operation unit 34, or may be stopped by the setting of the user.
この場合、コントローラ80のプロセッサ81は、便モードによる洗浄処理を実行する(S5)。なお、便モードによる洗浄処理は、洗浄処理部87により実行される。
また、洗浄処理を実行後に、適宜、換気処理が実行される。具体的には、換気処理は、例えば、S1において***物を検出していない間に(S1:No)、ブロア41のみを所定時間動作させる処理を繰り返すことにより実行される。この換気処理におけるブロア41の出力は、弱モードに設定される。なお、換気処理は、操作部34で受け付けた操作に応じて、途中で停止してもよいし、ユーザの設定により停止するようにしてもよい。 Then, when excrement is detected in the
In this case, the
In addition, after the cleaning process is performed, the ventilation process is appropriately performed. Specifically, the ventilation process is performed, for example, by repeating the process of operating only the
一方で、S3においてカップ部材10内に***物が検出されなかった場合であって(S3:No)、冷水パージ処理の終了から所定時間が経過し判定タイムオーバーとなっていないときには(S6:No)、S3の処理を継続する。
そして、S3においてカップ部材10内に***物が検出されなかった場合であって(S3:No)、冷水パージ処理の終了から所定時間が経過し判定タイムオーバーとなったときには(S6:Yes)、コントローラ80のプロセッサ81は、S1で検出した***物は尿と判定する(S7)。例えば、S3、S6、S7の処理は第2判定部86により実行される第2判定工程である。
この場合、コントローラ80のプロセッサ81は、尿モードによる洗浄処理及び乾燥処理を実行する(S8)。なお、尿モードによる洗浄処理は、洗浄処理部87により実行される。また、乾燥処理は、洗浄処理の完了後に、ポンプ63による洗浄水の供給を停止した状態で、ブロア41を所定時間動作させることにより実行される。
なお、便モードと尿モードにおいて乾燥時間は同じであってもよいし、便モードの乾燥時間を尿モードよりも長くしてもよい。
以上が***物吸引装置1により実行される***物の処理の流れである。 On the other hand, when no excrement is detected in thecup member 10 in S3 (S3: No), and a predetermined time has elapsed from the end of the cold water purge processing and the determination time-over has not occurred (S6: No) , Continue the process of S3.
Then, if no excrement is detected in thecup member 10 in S3 (S3: No), and a predetermined time has elapsed since the end of the cold water purge processing and the judgment time-out has occurred (S6: Yes), the controller The processor 81 of 80 determines that the excrement detected in S1 is urine (S7). For example, the processing of S3, S6, and S7 is a second determination step performed by the second determination unit 86.
In this case, theprocessor 81 of the controller 80 executes the washing process and the drying process in the urine mode (S8). The cleaning process in the urine mode is performed by the cleaning processing unit 87. The drying process is performed by operating the blower 41 for a predetermined time in a state where the supply of the washing water by the pump 63 is stopped after the completion of the washing process.
The drying time may be the same in the stool mode and the urine mode, or the drying time in the stool mode may be longer than in the urine mode.
The above is the flow of the excrement processing performed by theexcrement suction apparatus 1.
そして、S3においてカップ部材10内に***物が検出されなかった場合であって(S3:No)、冷水パージ処理の終了から所定時間が経過し判定タイムオーバーとなったときには(S6:Yes)、コントローラ80のプロセッサ81は、S1で検出した***物は尿と判定する(S7)。例えば、S3、S6、S7の処理は第2判定部86により実行される第2判定工程である。
この場合、コントローラ80のプロセッサ81は、尿モードによる洗浄処理及び乾燥処理を実行する(S8)。なお、尿モードによる洗浄処理は、洗浄処理部87により実行される。また、乾燥処理は、洗浄処理の完了後に、ポンプ63による洗浄水の供給を停止した状態で、ブロア41を所定時間動作させることにより実行される。
なお、便モードと尿モードにおいて乾燥時間は同じであってもよいし、便モードの乾燥時間を尿モードよりも長くしてもよい。

Then, if no excrement is detected in the
In this case, the
The drying time may be the same in the stool mode and the urine mode, or the drying time in the stool mode may be longer than in the urine mode.

And according to the excrement determination method by the excrement aspiration apparatus 1 and the excrement aspiration apparatus 1 described above, whether the excrement is stool based on the detection result of the excrement by the electrode unit 15 before and after the aspiration of the excrement It can accurately determine whether it is urine. Thereby, the misjudgment of the kind of excretion is suppressed, and the excretion can be processed appropriately.
また、***物吸引装置1では、***物の種類に応じたモードで洗浄部60を動作させることで、***物の種類に応じた適切な洗浄処理を実行することができる。

また、***物吸引装置1では、電極部15は、複数の電極ペアを有し、複数の電極ペアのうち少なくともいずれかを流れる電流値が所定値以上となった場合に、***物が有ると判定する。
こうすることで、電極部15の電極ペアに接する***物が導体となることで、各電極ペアに接する***物を検出することができる。また、カップ部材10に複数の電極ペアを設けることで、複数の箇所において***物を検出することができる。これにより、***物の検出範囲率を向上できる。 Further, in theexcrement suction apparatus 1, the electrode unit 15 has a plurality of electrode pairs, and if the current value flowing through at least one of the plurality of electrode pairs is equal to or more than a predetermined value, there is an excrement. judge.
By doing this, the excrement in contact with the electrode pair of theelectrode unit 15 becomes a conductor, and the excrement in contact with each electrode pair can be detected. Further, by providing a plurality of electrode pairs in the cup member 10, excrement can be detected at a plurality of places. Thereby, the detection range rate of excretion can be improved.
