For this reason, when there is much quantity of a processed material, the pressure loss when passing a processed material becomes large, and the quantity of the heating air which passes a processed material decreases. Then, the amount of heated air returning to the suction port of the blower 21 of the heated air supply means 20 is smaller than the heated air discharged from the discharge port 20f, and the pressure between the discharge port 20f and the suction port of the blower 21 is reduced.

生ゴミを撹拌して、内部のゴミを順次表面に露出させるようにすれば、生ゴミの全体を乾燥させることも可能である。
しかし、この場合には、撹拌翼等を設けなければならず、ゴミを破砕する場合と同様に上述したような問題が生じる。

(冷却機構)
第7発明の乾燥減容処理装置は、第1、第2、第3、第4、第5または第6発明において、前記冷却機構は、前記処理容器を通過した前記加熱空気が供給される筒状の冷却管を備えており、該冷却管には、前記処理容器の排気口と連通された流入口が形成されており、前記冷却管内の周方向から前記加熱空気が流入するように設けられていることを特徴とする。

第2発明によれば、分配部によって、加熱空気の一部が排気機構に排出され、給気機構によって外気が循環流路に供給される。つまり、循環する加熱空気の一部が外気と置換されるので、加熱空気中の水分量を低下させることができ、乾燥効率を向上させることができる。
第3発明によれば、被処理物の量が多い場合には、被処理物における圧力損失が大きくなって被処理物を通過する加熱空気の量が少なくなるが、被処理物を通過できない加熱空気はバイパス通路を介して循環機構に排出することができる。すると、供給口から循環機構までの間の圧力損失を低減することができるので、加熱空気の流量を低減させることなく適切な乾燥処理を行うことができる。

第5発明によれば、処理容器を装置から着脱できるので、処理容器を台所のシンクなどに置いておき、生ごみ入れなどとして使用することができる。そして、ごみを入れた処理容器をそのまま装置に取り付けることができるので、ごみ処理を容易にすることができる。しかも、収容容器が受皿から取り外せるので、受皿を外した収容容器を台所のシンクなどに設置して水切りなどとして使用することができる。そして、ごみが溜まって熱処理を行う際には、収容容器を装置まで運ばなければならないが、収容容器に受皿を取り付ければ、収容容器内のごみから垂れる水等を受け止めることができるから、水などを垂らすことなく、装置まで搬送することができる。さらに、収容容器内には、破砕用の刃物などの回転物を設置していないので、生ゴミ入れによく使用する市販されている不織布やネットなどの袋を収容容器に取り付けたままで処理を行うことができる。すると、乾燥処理終了後、袋ごとゴミを取り出すことができるので、そのままゴミを廃棄することができ、処理後のゴミの処理も容易になる。
(熱交換器の配置)
第6発明によれば、排気機構が冷却機構を備えているので、装置から排出される加熱空気の温度を低下させることができる。また、流入流路を流れる空気と排気流路を流れる空気との間で熱交換ができるような構造となっているので、外部から流入する空気を、排気流路から排出される空気によって予熱することができ、熱効率を向上させることができる。さらに、処理部と冷却部との間に上記熱交換構造を設けているので、スペースを有効活用することができる。とくに、処理部と冷却部とを着脱できるようにすれば、メンテナンス性を向上させることができる。
(冷却機構)
第7発明によれば、冷却管内に供給される加熱空気を、冷却管の内面に沿って流すことができる。すると、加熱空気と冷却管との接触効率を向上させることができるから、加熱空気の冷却を効率よく行うことができる。
第8発明によれば、脱臭部によって外部に排出する前に空気を脱臭することができる。しかも、冷却機構を通過した空気を脱臭するので、安価な活性炭でも脱臭ができる。よって、脱臭部を設けても、装置の価格を抑えることができる。
本実施形態の乾燥減容処理装置は、水分を含有する被処理物を処理するための装置であって、加熱空気を被処理物に接触させることによって被処理物を乾燥して減容するものである。
なお、処理対象となる被処理物は、水分を含有するものであればとくに限定されない。被処理物には、例えば、家庭から排出される生ゴミなどを挙げることができるが、これらに限定されるものではない。
図1~図3に示すように、本実施形態の乾燥減容処理装置1は、被処理物を入れて乾燥減容処理を行うための処理容器10と、この処理容器10を内部に収容するための収容空間2hを有するケース2とを備えている。このケース2内は、処理容器10内に加熱された加熱空気を供給する加熱空気供給手段20、加熱空気を処理容器10と加熱空気供給手段20との間で循環させる循環流路、循環流路内の加熱空気を外部に排気する排気機構、および、循環流路と外部との間を連通する給気機構が設けられている。
まず、処理容器10を説明する。
処理容器10は、ケース2の収容空間2hから着脱可能に設けられた部材である。つまり、処理容器10を装置から取り出すことができるようになっている。この処理容器10は、台所のシンクなどに置いておけば、生ごみ入れなどとして使用することができる。そして、ごみを入れた処理容器10をそのまま装置に取り付けることができるので、ごみ処理を容易にすることができる。
図5に示すように、処理容器10は、筒状の収容容器11と、この収容容器11の下端に設けられた受皿12とを備えている。
また、収容容器11の底部には、脚部11cが設けられている。この脚部11cの高さはとくに限定されないが、例えば 10~20mm程度である。
また、図8に示すように、収容容器11は、市販の水切りネットなどの袋Nを取り付けることができるようになっていることが好ましい。すると、乾燥処理終了後、袋Nごとゴミを収容容器11から取り出すことができるので、そのまま廃棄することができ、処理後のゴミの処理も容易になる。
具体的には、受皿12は、その外周縁に沿って、その内底を囲むように壁部12aが設けられている。この壁部12aの高さはとくに限定されないが、収容容器11の底部の脚部11cよりも長くなるように形成されている。例えば、20~30mm程度である。また、壁部12aは、その内径が収容容器11の下端の外径よりも大きくなるように設けられている。例えば、収容容器11の下端の外径よりも20~40mm程度大きく形成されている。
そして、収容容器11を受皿12に載せれば、収容容器11の底部に設けられている脚部11cによって、受皿12に収容容器11の底部11bと受皿12の内底との間に底部隙間12hが形成される。また、壁部12aの内径が収容容器11の下端の外径よりも大きいので、収容容器11の外周面と壁部12aとの間にも側部隙間12sが形成される。
このため、収容容器11の開口11hから加熱空気を供給すると、底部11bを通過し、底部隙間12hおよび側部隙間12sを通って、受皿12の外に排出される加熱空気の流れが形成される。よって、収容容器11内に被処理物を入れておけば、被処理物に確実に加熱空気を通過させることができる。
また、上述した収容容器11の底部11bに設けられた多数の貫通孔、底部隙間12h、側部隙間12sが特許請求の範囲にいう排気口に相当する。
上述した処理容器10では、隙間形成機構として、収容容器11の底部に脚部11cを設ける場合を説明した。隙間形成機構は、収容容器11の底部11bを受皿12の内底から浮かせて、両者の間に底部隙間12hを形成することができる構造であればとくに限定されない。
例えば、以下のごとき構造を受皿12に形成して、隙間形成機構としてもよい。
かかる台座部12dを設ければ、収容容器11の底部11bを台座部12dの保持面dsに載せると、収容容器11の底部11bと受皿12の内底との間に底部隙間12hを形成することができる。また、台座部12d間の空間によって、底部隙間12hと側部隙間12sとが連通されるから、収容容器11の底部11bを通過した加熱空気を、底部隙間12hおよび側部隙間12sを通して受皿12の外に排出させることができる。
収容容器11と受皿12は固定されていなくてもよいが、両者が固定できるようになっていれば、処理容器10を運ぶときに、受皿12を保持しなくても、収容容器11内のごみから垂れる水などを受皿12に受け止めさせることができる。しかも、収容容器11だけを持ては、受皿12も処理容器10を装置から取り出すことができる。したがって、処理容器10の運搬が容易になるし、処理容器10を装置に着脱する作業も容易になる。
しかも、収容容器11から受皿12から外し、収容容器11を台所のシンクなどに置いておけば、収容容器11を水切りなどとして使用することができる。
両者を着脱する場合において、両者を固定する機構はとくに限定されず、収容容器11と受皿12とが着脱できるようになっていればよく、例えば、以下のごとき構造をあげることができる。
図6に示すように、収容容器11の下端周囲には溝11gが設けられている。一方、受皿12の壁部12a内面には、溝11gがと係合する突起12pが設けられている。すると、収容容器11の溝11gに受皿12の突起12pを係合させれば両者を固定することができるし、溝11gから突起12pを離脱させれば分離することができる。
図1および図2に示すように、本実施形態の乾燥減容処理装置1のケース2は、略矩形をした縦型の容器であって、上部ケース2Aと、下部ケース2Bとから形成されている。
上部ケース2Aは、収容空間2hを有し、かつ、加熱空気供給手段20、循環流路が内蔵されたケースである。この上部ケース2A、加熱空気供給手段20などによって、処理部1Aが構成されている。下部ケース2Bは、後述する排気機構の冷却機構が内蔵されたケースであり、この下部ケース2B、冷却機構などによって冷却部1Bが構成されている。
そして、処理部1Aと冷却部1Bとは、冷却部1Bの上面と処理部1Aの下面とが対向するように積層されている。しかも、冷却部1Bの上面と処理部1Aの下面との間には、冷却機構によって冷却された空気を外部に排出する排気流路42、および、外部と連通された給気機構の流入流路51が形成されているが、詳細は後述する。
つぎに、処理部1Aを説明する。
処理部1Aは、上述したように、収容空間2hを有する上部ケース2Aと、このケース2Aに内蔵された加熱空気供給手段20、循環流路を備えている。
上部ケース2Aは、略矩形に形成されたケースであり、その上端に開口を有する収容空間2hを有している。この収容空間2hは、上述したように、処理容器10が収容される空間である。この収容空間2hは、処理容器10を内部に配置すると、処理容器10の外周面と収容空間2hの内側面との間に隙間30hが形成される程度の大きさに形成されているが、その理由は後述する。
上部ケース2A内において、前記収容空間2hの側方には、この収容空間2hと隔離された空間に加熱空気供給手段20が設けられている。
この加熱空気供給手段20は、例えば、ブロア(シロッコファン)などの空気を吸気口から吸引して排気口から排出する送風機21と、この送風機21の排気口と加熱空気供給通路20aとを接続する送風通路22と、この送風通路22に設けられた加熱機23とを備えている。
なお、送風機21の吸気口を配置する位置はとくに限定されないが、収容空間2hの下部に配置すると、収容空間2に供給される加熱空気が処理容器10の被処理物内を流れやすくなるので好ましい。
なお、送風通路22には、送風機21から供給される加熱空気の一部を冷却部1Bに排出する分配部30が設けられているが(図3参照)、詳細は後述する。
底部11bを通過した加熱空気は、底部隙間12hおよび側部隙間12sを通って、受皿12の外に排出される。受皿12の外に排出された加熱空気は処理容器10の外周面と収容空間2hと内側面との間に隙間30hに流入する。
すると、送風機21の吸気口が収容空間2hと連通されているので、受皿12の外に排出された加熱空気は、送風機21に吸引され、加熱機23によって加熱された後、再度収容容器11の開口11hに供給される。つまり、加熱空気は、加熱空気供給手段20と収容容器11との間を循環するのである。
しかも、加熱空気を循環させているので、加熱空気を全て排気する場合に比べて、熱効率を向上させることができる。
本実施形態の乾燥減容処理装置1では、加熱空気供給手段20の加熱空気供給通路20aの排出口20fから収容容器11の開口11hを通して収容容器11内の被処理物に加熱空気を供給し、この加熱空気に被処理物を通過させるような構造を採用している。このため、被処理物の量が多い場合には、被処理物を通過するときの圧力損失が大きくなって被処理物を通過する加熱空気の量が少なくなる。すると、排出口20fから排出される加熱空気に比べて、加熱空気供給手段20の送風機21の吸引口に戻る加熱空気の量が少なくなり、排出口20fと送風機21の吸引口との間の圧力損失が大きくなり、送風機21に加わる負荷が大きくなる。この負荷を低減させるためには、被処理物を通過する加熱空気の量と対応するように、排出口20fから収容容器11に供給する加熱空気の流量を少なくするような制御をしなければならなくなり、加熱空気供給手段20の制御が複雑になる。
また、処理容器10の外周面と収容空間2hと内側面との間の隙間30hは、特許請求の範囲にいうバイパス経路の一部を構成し、この隙間30hと、処理容器10を収容空間2h内に収容した状態で蓋2aを閉じたときに蓋2aの内面と処理容器10の収容容器11の上端との間に形成される隙間とによって特許請求の範囲にいうバイパス経路が形成される。
つぎに、冷却部1Bを説明する。
冷却部1Bの下部ケース2B内には、冷却機構を形成する円筒状の空間45hが形成されている。この空間45h内には、円筒状の脱臭部47が設けられている。この脱臭部47は、内筒状の通気性を有しない材料によって形成されたケース部47aと、その内部に配置された活性炭47bとによって形成されている。
図2に示すように、脱臭部47は、その中心軸と空間45hの中心軸とが一致するように配置されている。つまり、脱臭部47のケース部47aの外面と空間45hの外殻となる下部ケース2Bの壁との間に環状の空間が形成されるように、脱臭部47は空間45h内に配設されているのである。
また、脱臭部47は、その上端は下部ケース2Bの上端に取り付けられており、その下端は下部ケース2Bの下端の内面から離間した状態となるように設けられている。
送風通路22内の加熱空気は、その一部が分配部30の分岐管32および流入管31をこの順に流れて(図3中点線矢印)、空気通路41に流入し、開口45aから空間45h内に流入する。空間45h内に流入した加熱空気は、空間45hから脱臭部47内に流入し、この脱臭部47を通過した空気は、貫通穴を通過して排気流路42内に流入する。そして、排気流路42内に流入した空気は、排気流路42内を排気口Exに向かって流れて、排気口Exを通して外部に排出されるのである。
なお、脱臭部47の脱臭剤は、活性炭に限られず、どのようなものを使用してもよく、とくに限定されない。
また、空気通路41、開口45a、円筒状の空間45hによって特許請求の範囲にいう冷却部が形成されており、この冷却部、脱臭部47、排気流路42、排気口Exによって特許請求の範囲にいう排気機構が形成されている。
上述したように、分配部30によって一部の加熱空気が冷却部1Bに排出されることにより生じる、収容空間2hから排出される加熱空気の量と収容空間2h内の処理容器10に供給される加熱空気の量との差は、給気機構によって外部から収容空間2h内に供給される空気によって補填される。この場合、外部から収容空間2h内に供給される空気をそのまま収容空間2h内に供給してもよいが、以下のような熱交換機構によって予熱してから供給されることが好ましい。
そして、壁面の一部が上部ケース2Aの壁面2cとなった一の空間を排気流路42として、この空間を形成する壁面2cに排気口Exを形成する。また、壁面の一部が上部ケース2Aの壁面2cとなった他の空間であって、排気流路42と壁面(例えば、隔壁2d)を共用する空間を給気機構の流入通路51として、この空間を形成する壁面2cに空気流入口inを形成する。そして、上部ケース2A内に、流入通路51と収容空間2hとの間を連通する連通通路52を設ける。
しかも、上記のごとき構成とすれば、熱交換構造が処理部1Aと冷却部1Bとの間に形成できるので、スペースを有効活用することができる。
