Description

【０００１】
【発明の属する技術分野】
本発明は、主に一般室内で使用するポータブルトイレに関するものである。
【０００２】
【従来の技術】
従来から、ポータブルトイレを使用する際に、便槽から溢れたり、飛び跳ねたりした汚水（小水など）が床面に零れて汚れるのを防止するために汚水受け部なるものがポータブルトイレには設けられている。例えば、特許文献１では、外容器（便器本体）の開口部周縁に溝状の小水受け桶（汚水受け部）が外容器と一体的に形成されており、便容器（便槽）から外部に漏れる小水をこの小水受け桶に溜めることができるようになっている。
【０００３】
【特許文献１】
特開平１１−２５３３５４号公報
【０００４】
【発明が解決しようとする課題】
上記従来の技術では、小水受け桶が外容器と一体的に形成されているため、小水受け桶の洗浄が面倒であった。より具体的に言うと、特許文献１に記載された上記従来の技術では、小水受け桶が外容器と一体構造となっているので、洗浄する際には、便器が配置されている場所まで洗浄剤やブラシを持っていき、その場所で小水受け桶を洗浄しなければならなかった。しかも、便器の床面に少なからず洗浄剤などが飛び散ってしまうため、小水受け桶を洗浄した後で、洗浄剤などで汚れた床面を雑巾などで拭き取らなければならなかった。
【０００５】
本発明は、斯かる実情に鑑み、汚水受け部が簡単に取り外せる構造のポータブルトイレを提供することを目的とする。さらに、本発明は、汚水受け部の洗浄が容易なポータブルトイレを提供することにある。また、汚水受け部に入らなかった場合でも、予備の汚水受けを設けて床への汚水の汚染を効率的に防止できるポータブルトイレを提供することも本発明の目的である。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、請求項１に記載の発明では、便器本体の略中央部に便槽取付孔が設けられた便器本体部と、前記便槽取付孔の周縁部から外方に形成された座面部に着脱可能に取り付けられる汚水受け部と、前記汚水受け部に着脱可能に取り付けられる便槽とを有するポータブルトイレであって、前記便器本体部は、前記座面部の外側から上方へ延びる周壁部と、前記座面部から前記汚水受け部の下方に回り込むように設けられ、上方が開放された溝構造の補助汚水受け部と、をさらに備えていることを特徴とするポータブルトイレを提供する。
【０００７】
便槽から勢いよく溢れ出たり、飛び散ってきた汚水は、汚水受け部を越えて外部へ零れてしまうこともあるが、本発明によれば、便器本体部の座面部の外側に上方へ延びる周壁部が設けられている。この座面部は汚水受け部を係止する部分でもあるので、ここを通り越すと汚水受け部に汚水が入らない場合がある。しかし、本発明では、汚水受け部（座面部）を越えてきた汚水であっても、その外側の周壁部が汚水を遮って外部へ零れるのを防止できる。しかも、この周壁部は、汚水受け部が係止する座面部の外側から上方に延びるように設けられているから、周壁部に当たった汚水は、そのまま座面部と係止する汚水受け部の係止部上面から汚水受け部へと伝っていき、汚水受け部に溜められる。
【０００８】
しかし、汚水受け部の外側壁部分から外方に延設された係止部と座面部との間に取付不具合などで隙間が生じた場合には、その隙間から汚水が床面に漏れることも考えられる。
このような予期せぬ事態であっても汚水が床面に漏れないように、本発明では、便器本体部にさらに補助汚水受け部を備えているので、そこに汚水を溜めることができるようにしている。この補助汚水受け部は、座面部から汚水受け部の下方に回り込むように設けられており、上方が開放された溝構造のものである。
【０００９】
これにより、座面部と汚水受け部の係止部との間の隙間を伝ってきた（汚水受け部の裏側に回り込んだ）汚水は、そのまま本体部の内面を伝わって溝構造の補助汚水受け部に上方から入り込んできて、補助汚水受け部の内部に溜められるので、たとえ、隙間などに汚水が入り込んでも床面にまで汚水が零れることはない。
なお、この補助汚水受け部は、汚水受け部の下方に回り込むように設けられた溝構造であるので、汚水受け部の裏面側を伝わった汚水も、汚水受け部の裏面から離れると、その下部に位置する補助汚水受け部に落ちるので、床などには汚水が飛び散らないものである。
【００１０】
従って、この補助汚水受け部は、汚水受け部の下方に回り込むように構成され、汚水受け部の裏面（下面）に伝わった汚水が雫となって落ちる位置を受けるように配設されているものであればよい。具体的な構造は、汚水受け部の裏面部の構造や、汚水の漏れ量を考慮して適宜決定すれば良い。
【００１１】
また、補助汚水受け部は、汚水受け部の下方へどれだけ回り込んでも、回り込んでさえすれば全て含まれるものであるが、溝構造の汚水受け部の下方に形成された下向きの凸部（即ち、溝構造の溝底部）の頂上部を覆う程度まで回り込んで形成されているのが望ましい。下向き凸部の部分が、主に汚水が雫となって下方に落ちる場所だからである。従って、この下向きの凸部を覆う程度まで回り込んでいない場合には、汚水受け部の係止部と座面部との隙間を流れてきた汚水が汚水受け部の下面部を伝っていき、僅かであるが凸部から床面に滴下する場合も考えられるからである。
【００１２】
また、補助汚水受け部の大きさ（溝幅、溝深さ）は、汚水受け部より小さくすることができる。補助汚水受け部に溜まる汚水は、汚水受け部に溜まる汚水に比べて遥かに少ない量だからである。
【００１３】
補助汚水受け部の洗浄は、便槽と汚水受け部を取り外した後に、ティッシュや雑巾などでさっと拭き取れば十分である。何故なら、補助汚水受け部には、通常の使用では殆ど溜まることはないからである。また、雑巾などで拭き取る際にも、溜まっている汚水は少量なので、洗浄中に汚水が床面に零れることもない。
【００１４】
請求項２に記載の発明では、請求項１に記載のポータブルトイレにおいて、前記便槽は、上部が開放され、上部外周部の縁部に、外側から下方に向かう折り返し部を備え、前記汚水受け部は、前記便槽の上部縁部の外周部に沿って配設される上方が開放された溝構造を備えており、前記溝状の汚水受け部の内側壁部分の上部が、前記便槽の折り返し部の内方に入り込んで係合して前記便槽を保持する保持部を構成し、前記溝状の汚水受け部の外側壁部分の上部が外方に延設されて、前記座面部との係止部を構成している。
【００１５】
本発明のポータブルトイレは、便器本体部と汚水受け部と便槽とを備えて構成される。便器本体部は、略中央部に便槽取付孔が設けられており、この便槽取付孔の周縁部から外方に形成された座面部に汚水受け部が着脱可能に設けられ、さらに、この汚水受け部の内側縁部に便槽が着脱可能に取り付けられている。即ち、本発明のポータブルトイレは、便器本体部と汚水受け部と便槽とはそれぞれが別体で構成されており、着脱可能な便槽が着脱可能な汚水受け部を介して便器本体部の便槽取付孔に取り付けられた構成となっているのである。
【００１６】
そして、便槽は、上部が開放され、上部の外周縁部に、外側から下方に向かう折り返し部を備えて構成されている。また、汚水受け部は、便槽の上部縁部の外周部に沿って配設される上方が開放された溝構造となっており、この溝構造によって、上方から入り込んできた汚水が汚水受け内部に溜められるのである。しかも、便槽の上部縁部の外周に沿って配設されるものであるため、便槽のどの部分から汚水が溢れたり、飛び散ったりしてきても、汚水は汚水受け部に確実に溜められるのである。なお、この溝構造は、内部に入った汚水等を保持できる構造のものであれば特に限定されるものではない。
【００１７】
さらに、汚水受け部の前記溝状部分の内側壁部分（汚水受け部の便器本体内部側に位置する方の壁部分）の上部が、前記便槽の折り返し部の内方に入り込んで係合して便槽を保持する保持部を構成している。つまり、汚水受け部の内側壁部分に便槽の折り返し部を挿し入れることによって、便槽が汚水受け部に取り付けられるようになっているのである。そして、便層の上部開放部の周壁部の外側に沿って、汚水受け部の溝部が配設される構成となっている。
【００１８】
また、溝状の汚水受け部の外側壁部分（汚水受け部の便器本体外側に位置する側の壁部分）の上部が外方に延設されて、前記座面部との係止部を構成している。つまり、汚水受け部の便器本体部への取り付けは、汚水受け部の外側壁部分の係止部を便器本体部の便槽取付孔の上部に形成された座面部に係止することによってなされているのである。
【００１９】
このように構成された本発明によれば、便槽から溢れたり、飛び散った汚水（小水など）は、便槽の外周壁部の折り返し部を越えても、折り返し部の内方へ汚水受け部の内側壁部分が入り込んで取り付けられているため、汚水は折り返し部をたどって汚水受け部に溜められる。よって、汚水が床面に零れることがない。
【００２０】
溜まった汚水は、着脱可能に取り付けられた汚水受けを取り外して洗い場に持って行って洗浄すれば良いので簡単である。より詳細に言えば、便槽と汚水受けとの取り付け構造は、便槽の折り返し部を汚水受けの内側壁部分に挿し込む形式であり、汚水受けと便器本体部との取り付け構造は、汚水受けの外側壁部分と便器本体部の便槽取付孔の周縁部に形成された座面部に係止する形式であるため、便槽を上方へ持ち上げて取り外せば簡単に汚水受け部は取り外せる。よって、本発明によれば、便層を取り外した後、汚水受け部のみを簡単に取り外して洗い場に持って行って洗浄をすることができるのである。
【００２１】
しかも、汚水受け部が簡単に取り外せる着脱可能なものであるため、ポータブルトイレの便器本体部が配置された場所まで洗浄剤やブラシなどを持って行って、そこで洗浄をする必要はない。従って、従来のように汚水受け部の洗浄の際に、便器本体部が配置されている床面が汚れることもない。
【００２４】
請求項３に記載の発明は、請求項２に記載のポータブルトイレにおいて、前記汚水受け部の下面で、前記補助汚水受け部の上方には、下方に突出したリブが設けられていることを特徴とするものである。
【００２５】
本発明では、汚水受け部の下面であって、補助汚水受け部の上方の位置に、下方（即ち、補助汚水受け部の方向）に突出したリブが設けられているから、汚水受け部の係止部と座面部との間の隙間から入り込んできた汚水が汚水受け部の下面を伝ってきても、このリブがつい立となって、このリブを伝って汚水は下方に滴下する。そして、このリブが補助汚水受け部の上方の位置にあるから、滴下した汚水はそのまま補助汚水受けで確実に受け止められる。つまり、本発明によれば、汚水が床面に漏れて汚れるのをより確実に防ぐことができるものとなる。
【００２６】
また、リブを設けることにより、このリブから確実に汚水は滴下するので、補助汚水受け部の汚水受け部への回り込みはこのリブの位置まであれば十分である。従って、本発明のように構成することで、補助汚水受け部を小型にすることが可能となる。
【００２７】
ここで、本発明におけるリブは、汚水受け部の下面から下方に突出した形状のものであれば全て含まれるものである。また、このリブは、汚水受け部の下面全周に亘って設けられている方が確実に汚水が補助汚水受け部に滴下するので好ましいが、必ずしも全周に亘って設けられていなくても良い。何故なら、補助汚水受け部にまで流れてくる汚水は少量であるため、全周に亘ってリブが設けられていなくても、ほぼ確実に汚水は補助汚水受け部に滴下するからである。
【００２８】
請求項４に記載の発明は、請求項２又は３に記載のポータブルトイレにおいて、着脱可能な便座をさらに備えて構成され、前記便座の外周部が、前記便器本体部の周壁部の内側で、前記汚水受け部の係止部の上部に載置されていることを特徴とするものである。
【００２９】
本発明によれば、便座は、その外周部が便器本体部の周壁部の内側で汚水受け部の係合部の上部に載置されているため、汚水が便座を飛び越えても、周壁部が汚水の飛散を食い止めることができる。よって、汚水が床面に飛び散ったりして汚れることがない。しかも、周壁部に当たった汚水は壁伝いに流れて行き、汚水受け部の係止部と便器本体部の座面部との間の隙間を通って補助汚水受け部に回収され、そこに溜められるので、床面に汚水が零れることはない。
【００３０】
また、便座は、一般的に上方に盛り上がった断面略逆Ｕ字形状であるため、便槽内面に衝突して跳ね上がった汚水は、便槽と連通する便座の内部空間（逆Ｕ字断面の内側の空間）を通過して便槽の外へ飛び出ることもあるが、便座の外周部が汚水受け部の係止部の上部に載置されるように構成されているため、汚水は便座の外周部の内面で閉じ込められ、外部に飛び出ることなく汚水受け部に溜められる。つまり、便槽から跳ね上がって便座の内部に入り込んだ汚水も、外部へ飛び散ることなく汚水受け部に溜められ、床面に零れることはないのである。
【００３１】
【発明の実施の形態】
以下、本発明の実施の形態を図示例と共に説明する。尚、図中、図と同一の符号を付した部分は同一物又は相当物を表わしている。図１は、本発明の一実施形態に係るポータブルトイレの全体構成を示しており、便器本体の略中央部に便槽取付孔４が設けられた便器本体部１と、便器本体部１の内部に取り付けられた便槽２と、この便槽２の上部に配置されるＯ型の便座３と、その便座３の上部から便槽２の開口部を覆うように設けられた折り畳み可能な便器蓋５と、前記便器本体部１の上面後方部から上方に延びる背もたれ部６と、背もたれ部６の前部の位置で、便器本体部１の上面両側に着脱可能に取り付けられた二つの肘掛け１１ａ，１１ｂとで主に構成されている。なお、便座３の下側には汚水受け部２０及び補助汚水受け部２１が設けられているが、図１では図面の都合上図示しておらず、詳細は別の図面と共に後述する。
【００３２】
次に、本実施形態に係るポータブルトイレの詳細構造について図２と共に説明する。便器本体部１は、その上面部の略中央部に便槽取付孔４が設けられており、この便槽取付孔４の周縁部から外方（図２において右側）に、周方向に沿った平面状の座面部２２が形成されている。さらに、座面部２２の内側（図２において左側）の縁部（即ち、便槽取付孔４の周縁部）から下方に延びた断面略Ｕ字状（上方が開放された形状）の溝構造４１を有する補助汚水受け部２１が形成されている。また、座面部２２の外側縁部には、そこから上方へ延びる周壁部２４が形成されている。そして、これら補助汚水部２１、座面部２２、並びに周壁部２４は、便器本体部１と一体成形されている。
【００３３】
便槽２は、上方が開放されており、外周の上部縁部に、外側から下方に向かう折り返し部２５が形成されており、本体部１から着脱可能な別部材として構成される。なお、図示していないが、便槽２には取り外しを容易とするための回動可能な手提げハンドルが設けられている。
【００３４】
また、汚水受け部２０は、断面略Ｕ字状（上方が開放された形状）の溝構造４３となっており、この溝構造４３の外側壁部分２８の上端部から外方に延設された係止部２３が形成されており、この係止部２３が座面部２２の上面に載置され、本体部１から着脱可能な別体部材として構成されている。
【００３５】
これら便槽２と汚水受け部２０の便器本体部１への取り付けは、まず、便器本体部１の座面部２２に汚水受け部２０の係止部２３を上部から被せるように載置して取り付ける（係止させる）。そして、汚水受け部２０の内側壁部分２７の上部に便槽２の折り返し部２５を挿し込むと、内側壁部分２７の上部が便槽２の保持部となって便槽２をしっかりと保持して、便器本体部１へ汚水受け部２０及び便槽２の取り付けが完了する。なお、補助汚水受け部２１の内側壁部分の上端部が、汚水受け部２０の下面と当接しており、汚水受け部２０及び便槽２を下方から支えている。
【００３６】
さらに、断面略逆Ｕ字状の便座３は、その外周部が便器本体部１の周壁部２４の内側で、汚水受け部２０の係止部２３の上部に載置されている。そして、内周部の下端部は、便槽２の上部に張り出すように配設される。従って、便槽１内ではねた汚水は、便座３の内面側に入り込むと、そのまま外側に伝わって、汚水受け部２０の溝部内（溝構造４３の内側）に導かれる。
【００３７】
また、汚水受け部２０の下面には、下方に突出したリブ２６が設けられており、補助汚水受け部２１が、汚水受け部２０のリブ２６よりもやや便器本体部１内方側にまで回り込むようになっている。即ち、補助汚水受け部２１の内壁部３１の上端部は、前記リブ２６の内側部分で汚水受け部２０の下面に当接しており、汚水受け部２０の幅より補助汚水受け部２１の幅が小さく小型になっている。
【００３８】
この汚水受け部２０、及び、リブ２６は、図３〜図５に示すように、略Ｏ型で枠状外形の汚水受け部２０の下面部に全周に亘ってリブ２６が形成された構成となっている。なお、汚水受け部２０には、上方が開放した略矩形箱状の凹部３０が形成されており、手提げハンドル（図示せず）の一部を止め部４５に載置し、この凹部３０に便槽２の手提げハンドルを収納する。
【００３９】
この凹部３０は、手提げハンドルを掴む際に手指を入れ易くするために汚水受け部２０の下面より若干深く掘り下げられている。そのため、汚水受け部２０を取り外して床面に置いたときに凹部３０によって汚水受け部２０が斜めに傾いてしまうが、これを防止するために、本実施形態では、凹部３０が汚水受け部２０の下面から下方に突出した高さとほぼ同じ高さの位置まで突出する突起２９を汚水受け部２０の前方部の下面に設けている。
【００４０】
このように構成された本実施形態に係るポータブルトイレによれば、便槽２から飛び跳ねた汚水（小水など）は、便座３の下部では、図２の矢印Ａの如く便座３の内部を通って汚水受け部２０に溜められるため、床面に零れて汚れることはない。
【００４１】
また、便座３の上方に飛び出した汚水は周壁部２４で塞き止められ、矢印Ｂの如く、係止部２３と座面部２２との間の隙間を伝わって補助汚水受け部２１に溜められる。よって、便座３を越えてきた汚水でも補助汚水受け部２１に溜められ、床面に零れることはない。
【００４２】
さらに、係止部２３と座面部２２との間の隙間に入り込んだ汚水は、汚水受け部２０の下面を伝わって流れることもあるが、汚水受け部２０の下面から下方へ向かうリブ２６が設けられているから、汚水受け部２０の下面を伝って流れてきた汚水は、このリブ２６から確実に補助汚水受け部２１に滴下する。よって、確実に汚水は補助汚水受け部２１にて受け止められ、床面に汚水が漏れることはない。
【００４３】
汚水受け部２０を洗浄する場合には、便槽２を取り外してから汚水受け部２０を取り外し、洗い場まで運んで洗浄すれば良い。つまり、着脱可能な汚水受け部２０を便器本体部１から取り外して、簡単に洗うことができるのである。よって、ポータブルトイレの設置場所までブラシや洗浄剤などを持ち運んで、その場で洗浄するような面倒な作業は不要であり、ポータブルトイレの設置床面が汚水受け部２０の洗浄中に汚れてしまうこともない。
【００４４】
一方、補助汚水受け部２１は、便器本体部１と一体成形されているので、ポータブルトイレ設置場所で洗浄する必要があるが、この補助汚水受け部２１に溜まる汚水は少量であるから、ティッシュや雑巾で拭き取るだけの簡単な洗浄で済む。よって、ポータブルトイレ床面が汚れてしまうこともない。
【００４５】
【発明の効果】
以上、説明したように、本発明に係るポータブルトイレによれば、汚水受け部が簡単に取り外せ、汚水受け部の洗浄を簡単に行うことができるという優れた効果を奏し得る。しかも、汚水受け部を取り外せるため、汚水受け部を別の場所へ運んで洗浄することができる。よって、汚水受け部を洗浄する際にポータブルトイレの設置床面を汚すことがないという優れた効果を奏し得る。
【００４６】
さらに、汚水受け部を飛び越した汚水も補助汚水受け部に溜まるので、ポータブルトイレの周囲の床などを汚さない効果は、単体の汚水受け部を備えたものよりも更に効果的なものとなり、このポータブルトイレを使用する環境での清掃の手間が従来より少なく、かつ、周囲の清潔度が向上する利点もある。

BACKGROUND OF THE INVENTION
The present invention relates to a portable toilet mainly used in a general room.
[0002]
[Prior art]
Conventionally, when using a portable toilet, the portable toilet has been provided with a sewage receiving part to prevent spilled water (small water, etc.) overflowing or jumping from the toilet and spilling on the floor. It has been. For example, in Patent Document 1, a groove-shaped small water catcher (sewage catcher) is formed integrally with the outer container at the periphery of the opening of the outer container (toilet body main body). Small water that leaks into the water can be stored in this small water reservoir.
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 11-253354
[Problems to be solved by the invention]
In the above conventional technique, since the small water receptacle is integrally formed with the outer container, cleaning of the small water receptacle has been troublesome. More specifically, in the above-described conventional technique described in Patent Document 1, the small water receiving bowl is integrated with the outer container. I had to bring a cleaning agent and a brush, and I had to wash the small water receptacle there. In addition, since a lot of cleaning agent scatters on the floor surface of the toilet bowl, it was necessary to wipe off the floor surface that was soiled with the cleaning agent with a rag after cleaning the small water receptacle.
[0005]
In view of such circumstances, an object of the present invention is to provide a portable toilet having a structure in which a sewage receiving portion can be easily removed. Furthermore, this invention is providing the portable toilet with which washing | cleaning of a sewage receptacle part is easy. It is another object of the present invention to provide a portable toilet that can be provided with a spare sewage receiver and can effectively prevent sewage from being contaminated on the floor even if it does not enter the sewage receiver.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, in the invention described in claim 1, a toilet bowl body portion provided with a toilet bowl mounting hole at a substantially central portion of the toilet bowl body, and formed outward from a peripheral edge portion of the toilet bowl mounting hole. A portable toilet having a sewage receiving part that is detachably attached to the seat surface part and a toilet tub that is detachably attached to the sewage receiving part, wherein the toilet main body part is upward from the outside of the seat surface part. Provided is a portable toilet, further comprising: an extending peripheral wall portion; and an auxiliary sewage receiving portion having a groove structure that is provided so as to go around the sewage receiving portion from the seat surface portion and is opened upward. To do.
[0007]
The sewage that overflows or splashes vigorously from the toilet bowl may spill outside after passing through the sewage receiving part, but according to the present invention, the peripheral wall extends upward to the outside of the seat surface part of the toilet body part. Is provided. Since this seat surface part is also a part which latches a sewage receiving part, when passing through here, sewage may not enter a sewage receiving part. However, in this invention, even if it is the sewage which has passed the sewage receiving part (seat surface part), it can prevent that the outer peripheral wall part blocks | interrupts sewage and spills outside. In addition, since the peripheral wall portion is provided so as to extend upward from the outside of the seat surface portion to which the sewage receiving portion is locked, the sewage hitting the peripheral wall portion is directly engaged with the sewage receiving portion to be locked with the seat surface portion. It is transmitted from the upper surface of the stopper to the sewage receiving part and collected in the sewage receiving part.
[0008]
However, if there is a gap between the locking part and the seat surface part extending outward from the outer wall part of the sewage receiving part due to a mounting failure, etc., the sewage may leak from the gap to the floor surface. Conceivable.
In order to prevent sewage from leaking to the floor even in such an unexpected situation, in the present invention, the toilet main body is further provided with an auxiliary sewage receiving part, so that sewage can be collected therein. ing. The auxiliary sewage receiving portion is provided so as to go around from the seat surface portion to the lower side of the sewage receiving portion, and has a groove structure in which an upper portion is opened.
[0009]
As a result, the sewage that has been transmitted through the gap between the seat surface part and the locking part of the sewage receiving part (around the back side of the sewage receiving part) is directly transmitted through the inner surface of the main body part to receive the auxiliary sewage receiver of the groove structure. Since it enters the part from above and is stored inside the auxiliary sewage receiving part, even if sewage enters the gap or the like, the sewage does not spill to the floor.
In addition, since this auxiliary sewage receiving part is a groove structure provided so as to wrap around below the sewage receiving part, when the sewage transmitted along the back side of the sewage receiving part is separated from the back side of the sewage receiving part, Since it falls to the auxiliary sewage receiving part located in the sewage, the sewage is not scattered on the floor.
[0010]
Accordingly, the auxiliary sewage receiving portion is configured to wrap around the sewage receiving portion and is disposed so as to receive a position where the sewage transmitted to the back surface (lower surface) of the sewage receiving portion falls as a trap. If it is. What is necessary is just to determine a specific structure suitably in consideration of the structure of the back surface part of a sewage receiving part, and the leak amount of sewage.
[0011]
In addition, the auxiliary sewage receiving portion is included only if it wraps around below the sewage receiving portion as long as it wraps around, but the downward convex portion formed below the sewage receiving portion of the groove structure It is desirable that it is formed so as to cover the top of the groove bottom (that is, the groove bottom of the groove structure). This is because the downward convex portion is a place where sewage mainly becomes traps and falls downward. Therefore, when the sewage is not wrapped to the extent that it covers the downward convex part, the sewage flowing through the gap between the locking part of the sewage receiving part and the seat surface part travels along the lower surface part of the sewage receiving part, However, it is also conceivable that it drops from the convex portion onto the floor surface.
[0012]
Further, the size (groove width and groove depth) of the auxiliary sewage receiving part can be made smaller than that of the sewage receiving part. This is because the amount of sewage collected in the auxiliary sewage receiving part is much smaller than the sewage collected in the sewage receiving part.
[0013]
For cleaning the auxiliary sewage receiving part, it is sufficient to remove the toilet bowl and the sewage receiving part and then wipe them off with a tissue or a rag. This is because the auxiliary sewage receiving portion hardly accumulates in normal use. Also, when wiping with a rag or the like, the amount of accumulated sewage is small, so that sewage does not spill on the floor during cleaning.
[0014]
According to a second aspect of the present invention, in the portable toilet according to the first aspect of the present invention, the toilet tub is open at the top, and is provided with a folded portion that extends downward from the outside at the edge of the upper outer peripheral portion. The portion includes a groove structure that is disposed along the outer periphery of the upper edge of the toilet tub, and the upper portion of the inner wall portion of the groove-shaped sewage receiving portion is disposed on the toilet tub. A holding portion for holding the toilet tub by entering and engaging the inside of the folded portion of the fold, and an upper portion of an outer wall portion of the groove-shaped sewage receiving portion is extended outwardly to form the seat surface portion. The latching | locking part is comprised .
[0015]
The portable toilet of the present invention comprises a toilet bowl main body, a sewage receiving part, and a toilet bowl. The toilet body is provided with a stool mounting hole in a substantially central part, and a sewage receiving part is detachably provided on a seat surface part formed outward from the peripheral edge of the stool mounting hole. A toilet bowl is detachably attached to the inner edge of the sewage receiving part. That is, in the portable toilet of the present invention, the toilet bowl main body, the sewage receiving section, and the toilet tub are each configured separately, and the detachable toilet tub is attached to the toilet bowl main body via the detachable sewage receiving section. It is the structure attached to the toilet bowl attachment hole.
[0016]
And the upper part is open | released and the toilet bowl is provided with the folding | returning part which goes to the downward direction from the outer side in the outer periphery part of an upper part. In addition, the sewage receiving part has a groove structure opened along the outer periphery of the upper edge of the toilet tub, and this sewage structure allows sewage that has entered from above to enter the sewage receiving part. It is stored in. In addition, since it is arranged along the outer periphery of the upper edge of the toilet bowl, the sewage can be reliably collected in the sewage catching section no matter what part of the toilet bowl overflows or splatters. is there. The groove structure is not particularly limited as long as it has a structure capable of holding sewage and the like contained therein.
[0017]
Furthermore, the upper part of the inner wall part of the groove-shaped part of the sewage receiving part (the wall part located on the inside of the toilet main body of the sewage receiving part) enters the inside of the folded part of the toilet and engages therewith. A holding part for holding the toilet bowl. That is, the toilet tub is attached to the sewage receiving portion by inserting the folded portion of the toilet tub into the inner wall portion of the sewage receiving portion. And the groove part of a sewage receptacle part is arrange | positioned along the outer side of the surrounding wall part of the upper open part of a feces layer.
[0018]
Further, the upper portion of the outer wall portion of the groove-shaped sewage receiving portion (the wall portion on the side of the toilet body outside the sewage receiving portion) is extended outward to form a locking portion with the seat surface portion. ing. In other words, the sewage receiving part is attached to the toilet body part by engaging the engaging part of the outer wall portion of the sewage receiving part with the seat surface part formed in the upper part of the toilet bowl attaching hole of the toilet body part. It is.
[0019]
According to the present invention configured as described above, the sewage (such as small water) overflowing or splashing from the toilet tub receives the sewage inward of the turn-up portion even after the turn-up portion of the outer peripheral wall portion of the stool tub. Since the inner wall portion of the part enters and is attached, the sewage traces the folded part and is stored in the sewage receiving part. Therefore, sewage does not spill on the floor.
[0020]
The accumulated sewage can be easily removed by removing the sewage receiver attached in a detachable manner and taking it to the washing station for cleaning. More specifically, the attachment structure of the toilet tank and the sewage receptacle is a form in which the folded portion of the toilet tub is inserted into the inner wall portion of the sewage receptacle, and the attachment structure of the sewage receptacle and the toilet body portion is the sewage receptacle. Since it is a form which latches to the outer peripheral wall part and the seat surface part formed in the peripheral part of the toilet bowl attachment hole of the toilet bowl main-body part, if a toilet bowl is lifted up and removed, a sewage receptacle part can be removed easily. Therefore, according to the present invention, after removing the stool layer, only the sewage receiving part can be easily removed and brought to the washing place for washing.
[0021]
In addition, since the sewage receiving part can be easily removed and attached, it is not necessary to carry the cleaning agent or brush to the place where the toilet body part of the portable toilet is placed and wash it there. Therefore, the floor surface on which the toilet main body is disposed does not become dirty when the sewage receiving part is washed as in the prior art.
[0024]
According to a third aspect of the present invention, in the portable toilet according to the second aspect, a rib projecting downward is provided on the lower surface of the sewage receiving part and above the auxiliary sewage receiving part. It is what.
[0025]
In the present invention, a rib protruding downward (that is, in the direction of the auxiliary sewage receiving part) is provided on the lower surface of the sewage receiving part and above the auxiliary sewage receiving part. Even if the sewage that has entered from the gap between the stop portion and the seating surface has traveled along the lower surface of the sewage receiving portion, the rib is standing upright, and the sewage is dripped downward along the rib. And since this rib exists in the upper position of an auxiliary | assistant sewage receiving part, the dripped sewage can be reliably received with an auxiliary | assistant sewage receiver as it is. That is, according to this invention, it can prevent more reliably that dirty water leaks to a floor surface, and gets dirty.
[0026]
Further, since the sewage is surely dripped from the rib by providing the rib, it is sufficient that the auxiliary sewage receiving part wraps around the sewage receiving part up to the position of the rib. Therefore, by configuring as in the present invention, the auxiliary sewage receiving portion can be reduced in size.
[0027]
Here, all the ribs in the present invention are included if they have a shape protruding downward from the lower surface of the sewage receiving portion. In addition, it is preferable that the ribs are provided over the entire lower surface of the sewage receiving unit because the sewage is surely dropped on the auxiliary sewage receiving unit. However, the ribs are not necessarily provided over the entire circumference. . This is because the amount of sewage flowing to the auxiliary sewage receiving part is small, so that even if no rib is provided over the entire circumference, the sewage almost certainly drops on the auxiliary sewage receiving part.
[0028]
The invention according to claim 4 is the portable toilet according to claim 2 or 3, further comprising a removable toilet seat, the outer peripheral portion of the toilet seat is inside the peripheral wall portion of the toilet body main body, It is mounted on the upper part of the latching | locking part of the said sewage receiving part.
[0029]
According to the present invention, since the outer peripheral portion of the toilet seat is placed on the upper portion of the engaging portion of the sewage receiving portion on the inner side of the peripheral wall portion of the toilet body, the peripheral wall portion does not move even if sewage jumps over the toilet seat. It can stop the scattering of sewage. Therefore, sewage does not scatter and get dirty on the floor. Moreover, the sewage that hits the peripheral wall part flows along the wall, is collected in the auxiliary sewage receiving part through the gap between the locking part of the sewage receiving part and the seat surface part of the toilet body part, and is stored there. Therefore, sewage does not spill on the floor.
[0030]
In addition, since the toilet seat generally has a substantially inverted U-shaped section that rises upward, the sewage that collides with the inner surface of the toilet tub and jumps up is the interior space of the toilet seat that communicates with the toilet tub (with an inverted U-shaped cross section). May pass through the inner space) and jump out of the toilet bowl, but the outer periphery of the toilet seat is configured to be placed on top of the locking portion of the sewage receiving portion. It is confined on the inner surface of the outer peripheral part and is stored in the sewage receiving part without jumping out to the outside. In other words, the sewage that jumps up from the toilet and enters the toilet seat is stored in the sewage receiving portion without splashing outside and does not spill on the floor.
[0031]

In addition, although the sewage receiving part 20 and the auxiliary | assistant sewage receiving part 21 are provided in the lower side of the toilet seat 3, it is not shown in figure for convenience of drawing in FIG. 1, and details are later mentioned with another drawing.
[0032]
Next, the detailed structure of the portable toilet according to the present embodiment will be described with reference to FIG. The toilet main body 1 is provided with a toilet mounting hole 4 at a substantially central portion of the upper surface thereof, and extends outward from the peripheral edge of the toilet mounting hole 4 (right side in FIG. 2) in the circumferential direction. A planar seat surface portion 22 is formed. Further, a groove structure 41 having a substantially U-shaped cross section (a shape in which the upper part is opened) extending downward from an inner edge (left side in FIG. 2) of the seat surface portion 22 (that is, a peripheral edge of the toilet tub mounting hole 4). A supplementary sewage receiving portion 21 having the above is formed. Further, a peripheral wall portion 24 extending upward from the outer edge portion of the seat surface portion 22 is formed. And these auxiliary sewage part 21, the seat surface part 22, and the surrounding wall part 24 are integrally molded with the toilet bowl main-body part 1. FIG.
[0033]
The toilet tub 2 is open at the top, and is formed as a separate member that can be attached to and detached from the main body 1 by forming a folded portion 25 from the outside to the bottom at the upper edge of the outer periphery. Although not shown, the toilet tub 2 is provided with a rotatable hand handle for easy removal.
[0034]
Further, the sewage receiving portion 20 has a groove structure 43 having a substantially U-shaped cross section (a shape in which the upper part is opened), and extends outward from the upper end portion of the outer wall portion 28 of the groove structure 43. A locking portion 23 is formed, and the locking portion 23 is placed on the upper surface of the seating surface portion 22 and is configured as a separate member that can be detached from the main body portion 1.
[0035]
The toilet tank 2 and the sewage receiving part 20 are attached to the toilet main body 1 by first placing and attaching the locking part 23 of the sewage receiving part 20 on the seat surface part 22 of the toilet main body 1 from above. (Lock). When the folded portion 25 of the toilet tub 2 is inserted into the upper portion of the inner wall portion 27 of the sewage receiving portion 20, the upper portion of the inner wall portion 27 becomes a holding portion of the toilet tub 2 and holds the toilet tub 2 firmly. Thus, the attachment of the sewage receiving portion 20 and the toilet tub 2 to the toilet body 1 is completed. In addition, the upper end part of the inner wall part of the auxiliary | assistant sewage receiving part 21 is contact | abutting with the lower surface of the sewage receiving part 20, and supports the sewage receiving part 20 and the toilet bowl 2 from the downward direction.
[0036]
Furthermore, the toilet seat 3 having a substantially inverted U-shaped cross section is placed on the upper portion of the locking portion 23 of the sewage receiving portion 20 inside the peripheral wall portion 24 of the toilet main body 1. And the lower end part of an inner peripheral part is arrange | positioned so that it may protrude over the upper part of the toilet bowl 2. FIG. Therefore, when the sewage splashed in the toilet tub 1 enters the inner surface side of the toilet seat 3, the sewage is transmitted to the outside as it is and is guided into the groove of the sewage receiving part 20 (inside the groove structure 43).
[0037]
Further, a rib 26 protruding downward is provided on the lower surface of the sewage receiving part 20, and the auxiliary sewage receiving part 21 wraps around to the inner side of the toilet main body 1 slightly from the rib 26 of the sewage receiving part 20. It is like that. That is, the upper end portion of the inner wall portion 31 of the auxiliary sewage receiving portion 21 is in contact with the lower surface of the sewage receiving portion 20 at the inner portion of the rib 26, and the width of the auxiliary sewage receiving portion 21 is larger than the width of the sewage receiving portion 20. It is small and small.
[0038]
As shown in FIGS. 3 to 5, the sewage receiving portion 20 and the rib 26 are configured such that the ribs 26 are formed on the entire lower surface of the sewage receiving portion 20 having a substantially O-shaped frame shape. It has become. The sewage receiving portion 20 is formed with a substantially rectangular box-shaped recess 30 that is open upward, and a part of a hand handle (not shown) is placed on the stopper 45, and the toilet 30 Stores the handbag handle of tank 2.
[0039]
The concave portion 30 is dug slightly deeper than the lower surface of the sewage receiving portion 20 in order to make it easier to insert fingers when grasping the handle. Therefore, when the sewage receiving part 20 is removed and placed on the floor, the sewage receiving part 20 is inclined obliquely by the recessed part 30. In order to prevent this, the recessed part 30 is formed in the sewage receiving part 20 in this embodiment. A protrusion 29 is provided on the lower surface of the front portion of the sewage receiving portion 20 so as to protrude to a position substantially the same as the height protruding downward from the lower surface.
[0040]
According to the portable toilet according to the present embodiment configured as described above, the sewage (such as small water) jumping from the toilet tub 2 passes through the inside of the toilet seat 3 as indicated by an arrow A in FIG. Since it is stored in the sewage receiving part 20, it does not spill on the floor and become dirty.
[0041]
Further, the sewage that has jumped out above the toilet seat 3 is blocked by the peripheral wall portion 24 and is stored in the auxiliary sewage receiving portion 21 through the gap between the locking portion 23 and the seat surface portion 22 as indicated by an arrow B. Therefore, even the sewage that has passed over the toilet seat 3 is collected in the auxiliary sewage receiving part 21 and does not spill on the floor.
[0042]
Further, the sewage that has entered the gap between the locking part 23 and the seat surface part 22 may flow along the lower surface of the sewage receiving part 20, but a rib 26 directed downward from the lower surface of the sewage receiving part 20 is provided. Therefore, the sewage flowing along the lower surface of the sewage receiving part 20 is surely dropped from the rib 26 onto the auxiliary sewage receiving part 21. Therefore, the sewage is reliably received by the auxiliary sewage receiving part 21, and the sewage does not leak to the floor surface.
[0043]
When washing the sewage receiving part 20, the sewage receiving part 20 may be removed after removing the toilet tub 2 and carried to the washing place for washing. That is, the detachable sewage receiving part 20 can be removed from the toilet body body 1 and easily washed. Therefore, the troublesome work of carrying the brush or cleaning agent to the place where the portable toilet is installed and cleaning it on the spot is unnecessary, and the floor surface where the portable toilet is installed becomes dirty during cleaning of the sewage receiving portion 20. There is nothing.
[0044]
On the other hand, since the auxiliary sewage receiving part 21 is formed integrally with the toilet body 1, it is necessary to wash at the place where the portable toilet is installed. However, since the sewage collected in the auxiliary sewage receiving part 21 is small, Simply clean with a rag. Therefore, the portable toilet floor is not contaminated.
[0045]
【The invention's effect】
As described above, according to the portable toilet according to the present invention, the sewage receiving part can be easily removed and the sewage receiving part can be easily cleaned. Moreover, since the sewage receiving part can be removed, the sewage receiving part can be carried to another place for cleaning. Therefore, it is possible to achieve an excellent effect that the floor surface of the portable toilet is not soiled when cleaning the sewage receiving portion.
[0046]
Furthermore, since the sewage that jumps over the sewage catcher collects in the auxiliary sewage catcher, the effect of not polluting the floor around the portable toilet is even more effective than that with a single sewage catcher. There is also an advantage that the time required for cleaning in an environment where a portable toilet is used is less than conventional, and the cleanliness of the surroundings is improved.
