Description

【０００１】
【発明の属する技術分野】
本発明は、炊事場から出る野菜、魚介等の厨芥物に代表され生ごみを処理する生ごみ処理装置に関する。
【０００２】
【従来の技術】
厨芥物等の生ごみは、水分を多く含んでいるため、通常の焼却処理には不向きであり、一般に廃棄処理が厄介である。生ごみに含まれる多量の水分は、焼却効率を低下させるからである。生ごみの投棄は環境汚染の原因になる。また、生ごみの肥料等への転用もあるが、未処理の生ごみをそのまま肥料として使用することはできない。
【０００３】
【発明が解決しようとする課題】
従来、生ごみの加熱処理が提案されているが、加熱によって生じた水蒸気の外気への放出は悪臭の原因となる。そこで、脱臭処理が必要となるが、従来、触媒方式、活性炭方式等の方法がある。触媒方式では、十分な脱臭効果を得るには、２００〜４００℃の高温に触媒を保持しなければならず、しかも、触媒を通過させる風速の高速化が必要であるため、加熱が厄介であり、家庭用等には不向きである。また、水蒸気には種々の臭いが混じっているため、活性炭方式では、脱臭効果が得られない場合がある。しかも、活性炭が臭い粒子を吸収するので、その飽和が脱臭効果を低下させ、定期的に交換する必要がある。また、その他の方式として、オゾン脱臭、白金脱臭、バイオ脱臭等が提案されているが、悪臭を完璧に取り除くことが困難である。
【０００４】
そこで、本発明は、簡易な乾燥処理により生ごみの廃棄処理の容易化を実現した生ごみ処理装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明の生ごみ処理装置は、生ごみ（４）を収容する容器（２）、生ごみを加熱する加熱手段（ヒータ１４）、加熱によって生じた水蒸気（３）を前記容器外に導いて水（凝縮水６０）を凝縮させた後、空気を前記容器に帰還させる分離手段（放熱器４６、気液分離室５６）、水蒸気から凝縮、分離させた前記水を前記容器内に作用する圧力に応じて前記容器外に排出する排出手段（排水管６２）を備えて、加熱により生ごみから発生する水蒸気を循環冷却させ、空気と水とに分離、容器及び循環系統を減圧させ、かつ、容器内圧力を一定に維持し、生ごみ処理の無臭化とともに、生ごみの乾燥処理による減量化を実現し、生ごみの廃棄処理の容易化を図っている。
【０００６】
請求項１に係る本発明の生ごみ処理装置は、半円筒状の底面部を備え、生ごみ（４）を収容する容器（２）と、この容器の前記底面部に設置され、前記容器内の前記生ごみを加熱する加熱手段（ヒータ１４）と、前記容器の開口部に設置された蓋の開閉を検出する開閉センサ（１２）と、前記容器の底面部に平行に設置された回転軸にスクレーパ（２２）を取り付け、このスクレーパの最外周面を前記容器の底面部に離間させ、前記回転軸とともに回転する前記スクレーパにより、前記容器内の生ごみを攪拌する攪拌手段と、前記回転軸に回転力を付与するモータ（２４）と、前記加熱手段の加熱によって前記容器内に生じた水蒸気を前記容器外に導いて前記水蒸気から水を凝縮させて分離し、水が分離された空気を前記容器に帰還させる分離手段（放熱器４６、気液分離室５６）と、この分離手段に前記容器から前記水蒸気を流す管路に設置され、前記容器から前記水蒸気をモータの回転によって前記分離手段に導くファン（４０）と、前記分離手段で得られた前記水を前記容器内に作用する圧力に応じて前記容器外に排出する排出手段（排水管６２）と、前記容器に生じる水蒸気の温度を検出する温度検出手段（温度センサ４４）と、前記加熱手段の加熱動作、前記攪拌手段の攪拌動作、前記ファンの回転動作を制御する制御手段（制御演算装置７０）とを備え、前記制御手段は、前記開閉センサが前記蓋を閉じていることを検出したことを条件に、前記加熱手段の加熱動作及び前記攪拌手段の攪拌動作及び前記ファンの回転動作を開始させ、前記水蒸気の温度が所定温度に到達したとき、前記加熱手段の前記加熱動作を停止させ、前記加熱動作の停止の後、前記水蒸気の温度が所定温度まで低下したとき、前記攪拌手段の攪拌動作及び前記ファンの回転動作を停止させることを特徴とする。
【０００７】
このような構成とすれば、容器に収容された生ごみは加熱手段から加えられる熱により加熱される。その結果、生ごみは収縮するとともに、多量の水蒸気を発生する。この水蒸気が漏れると、悪臭の原因となる。そこで、この水蒸気を容器外に漏洩させることなく容器外に導き、冷却させることにより、水を凝縮させ、容器及び分離手段を含む循環系統を減圧させる。即ち、容器内の圧力が一定に維持される。水蒸気から凝縮した水は、容器内に作用する圧力に応じて前記容器外に排出手段を通して排出される。この結果、加熱による生ごみの熱収縮とともに加熱処理の無臭化を図って生ごみ廃棄の容易化を実現している。
この生ごみ処理装置では、前記容器内の前記生ごみを攪拌する攪拌手段（スクレーパ２２、モータ２４）を備えているので、この攪拌手段により容器内の生ごみが攪拌されて満遍なく生ごみが加熱される。
また、前記加熱手段は、前記容器から出る水蒸気の温度が所定温度に到達したとき、前記加熱動作を停止させるので、生ごみの加熱制御に循環空気温度を制御情報として活用し、生ごみの異常加熱を防止している。
この場合、前記制御手段は、前記開閉センサが前記蓋を閉じていることを検出したことを条件に、前記加熱手段の加熱動作及び前記攪拌手段の攪拌動作及び前記ファンの回転動作を開始させ、前記水蒸気の温度が所定温度に到達したとき、前記加熱手段の前記加熱動作を停止させ、前記加熱動作の停止の後、前記水蒸気の温度が所定温度まで低下したとき、前記攪拌手段の攪拌動作及び前記ファンの回転動作を停止させる。
【０００８】
請求項２に係る本発明の生ごみ処理装置は、半円筒状の底面部を備え、生ごみ（４）を収容する容器（２）と、この容器の前記底面部に設置され、前記容器内の前記生ごみを加熱する加熱手段（ヒータ１４）と、前記容器の開口部に設置された蓋の開閉を検出する開閉センサ（１２）と、前記容器の底面部に平行に設置された回転軸（１８）にスクレーパ（２２）を取り付け、このスクレーパの最外周面を前記容器の底面部に離間させ、前記回転軸とともに回転する前記スクレーパにより、前記容器内の生ごみを攪拌する攪拌手段と、前記回転軸に回転力を付与するモータ（２４）と、前記容器に生じた水蒸気（３）を前記容器外に導き、前記水蒸気から分離された空気を前記容器に戻す循環路（３６）と、この循環路に導かれた前記水蒸気を冷却し、前記水蒸気から水を凝縮させて分離させる凝縮手段（放熱器４６、気液分離室５６）と、この凝縮手段で分離させた前記水を前記容器及び前記循環路に作用する圧力に応じて前記容器外に排出する排出手段（排水管６２）と、前記凝縮手段に前記容器から前記水蒸気を流す循環路に設置され、前記容器から前記水蒸気をモータの回転によって前記分離手段に導くファン（４０）と、前記容器に生じる水蒸気の温度を検出する温度検出手段（温度センサ４４）と、前記加熱手段の加熱動作、前記攪拌手段の攪拌動作、前記ファンの回転動作を制御する制御手段（制御演算装置７０）とを備え、前記制御手段は、前記開閉センサが前記蓋を閉じていることを検出したことを条件に、前記加熱手段の加熱動作及び前記攪拌手段の攪拌動作及び前記ファンの回転動作を開始させ、前記水蒸気の温度が所定温度に到達したとき、前記加熱手段の前記加熱動作を停止させ、前記加熱動作の停止の後、前記水蒸気の温度が所定温度まで低下したとき、前記攪拌手段の攪拌動作及び前記ファンの回転動作を停止させることを特徴とする。
【０００９】
即ち、請求項２に係る本願発明では、前記分離手段を水蒸気から水を分離させる凝縮手段、凝縮手段で前記水を凝縮させた後、空気のみを前記容器側に戻す循環路に具体化している。したがって、加熱手段による加熱によって生じた水蒸気が容器から凝縮手段に導かれ、冷却により水蒸気から水が凝縮される。この凝縮手段で前記水を分離させた空気を前記容器側に循環路を通して戻すことにより、循環、冷却させて容器内の圧力を一定に維持し、水蒸気から凝縮した水は、容器内に作用する圧力に応じて前記容器外に排出手段を通して排出される。この結果、加熱処理による生ごみの収縮化とともに無臭化処理を可能にし、生ごみ廃棄の容易化を達成している。
この生ごみ処理装置では、前記容器内の前記生ごみを攪拌する攪拌手段（スクレーパ２２、モータ２４）を備えているので、この攪拌手段により容器内の生ごみが攪拌されて満遍なく生ごみが加熱される。
また、前記加熱手段は、前記容器から出る水蒸気の温度が所定温度に到達したとき、前記加熱動作を停止させるので、生ごみの加熱制御に循環空気温度を制御情報として活用し、生ごみの異常加熱を防止している。
この場合、前記制御手段は、前記開閉センサが前記蓋を閉じていることを検出したことを条件に、前記加熱手段の加熱動作及び前記攪拌手段の攪拌動作及び前記ファンの回転動作を開始させ、前記水蒸気の温度が所定温度に到達したとき、前記加熱手段の前記加熱動作を停止させ、前記加熱動作の停止の後、前記水蒸気の温度が所定温度まで低下したとき、前記攪拌手段の攪拌動作及び前記ファンの回転動作を停止させる。
【００１０】
請求項１又は２記載の生ごみ処理装置において、前記排出手段は、屈曲した管体を備え、その管体の形状と重力とを以て前記水を滞留させ、前記分離手段又は前記循環路を通じて作用する圧力により、又は、水の滞留量が所定量を越えるとき、その水を排出させるトラップ（臭気トラップ６４）を備えてなることを特徴とする。即ち、排出手段側に導かれた水を悪臭防止に利用している。トラップに溜められた水は、重力作用で管路の屈曲部に溜められ、外部と循環路とを分離する機能を持つが、循環路側の圧力が高くなり、溜められている水の遮断機能を越えるとき、又は、滞留量が所定量を越えるとき、滞留している水が排出される。しかしながら、水はトラップ内で十分に冷却されるため、悪臭源になることはない。
【００１１】
請求項１又は２記載の生ごみ処理装置において、前記容器内に発生した水蒸気を強制的に前記分離手段又は前記循環路に導く圧送手段（循環用ファン４０、ファンモータ４２）を備えたことを特徴とする。即ち、圧送手段によって容器内の水蒸気を分離手段又は循環路に間断なく循環させることができ、その循環、冷却処理が行われる。
【００１２】
請求項１又は２記載の生ごみ処理装置において、前記スクレーパは、前記回転軸に放射状に取り付けられた支持腕に取り付けられ、その最外周面が前記容器の底面部に僅かに離間したことを特徴とする。即ち、スクレーパにより容器内の生ごみが攪拌されて満遍なく生ごみが加熱される。
【００１３】
請求項１又は２記載の生ごみ処理装置において、前記加熱手段は、前記生ごみの加熱温度又は前記容器内温度に応じて制御されることを特徴とする。即ち、生ごみの加熱にフィードバック制御を活用している。このような制御によって生ごみの異常加熱が防止できる。
【００１４】
請求項１又は２記載の生ごみ処理装置において、前記温度検出手段は、前記容器から前記水蒸気を取り出す送気室に設置されたことを特徴とする。
【００１５】
請求項１又は２記載の生ごみ処理装置において、前記加熱手段の動作停止後の所定時間、前記容器内の空気を前記分離手段又は前記循環路に循環させることを特徴とする。即ち、空気循環により容器内の冷却を図る。
【００１６】
請求項１又は２記載の生ごみ処理装置において、前記加熱手段の動作停止後の循環する空気の温度が所定温度に低下するまで、前記容器内の空気を前記分離手段又は前記循環路に循環させることを特徴とする。即ち、空気循環により容器内の冷却を図っており、温度を制御情報に使用しているため、信頼性のある冷却処理が可能となる。
【００１７】
【発明の実施の形態】
以下、本発明を図面に示した実施形態を参照して詳細に説明する。
【００１８】
図１は、本発明の生ごみ処理装置の一実施形態を示している。
【００１９】
この生ごみ処理装置には、密閉される容器２が設けられ、この容器２に加熱処理すべき生ごみ４が収容される。容器２は、生ごみ４を加熱する釜であり、この実施形態では、容器２の底面は半円筒を成す湾曲面で形成されているが、半球形であってもよい。この容器２には、機械的な接触に対する耐磨耗性が高く、強度、高熱酸化、生ごみ４が持つ酸、アルカリに対する耐蝕材料としてステンレス、チタン等の金属材料やセラミックス等を用いることができる。この容器２には、生ごみ４の装填又は処理後のごみを取り出すための開口部６が形成されており、この開口部６を開閉する蓋８がヒンジ１０で開閉可能に設けられている。容器２は、蓋８によって密閉状態に保持される。また、容器２の開口部６の近傍には、蓋８の開閉を検出する開閉センサとしてスイッチ１２が設けられている。なお、蓋８を自動開閉する手段として自動開閉機構を設けてもよい。
【００２０】
容器２には、その外底面部側に容器２内の生ごみ４を加熱するヒータ１４が設置されている。このヒータ１４は、例えば、ニクロム線で構成される。このヒータ１４には温度センサ１６が併設されている。また、容器２には、生ごみ４を攪拌する攪拌手段が設けられている。即ち、容器２の中央には回転軸１８が取り付けられ、この回転軸１８には複数の支持腕２０が取り付けられ、この支持腕２０の先端部にスクレーパ２２が取り付けられている。各スクレーパ２２は、回転によって生ごみ４を掻き上げるとともに、容器２の内面への生ごみ４の付着を防止する羽であって、容器２の内壁面を損傷しない程度の金属材料で構成する。そのため、スクレーパ２２の最外周面は、容器２の内壁面より僅かに離間して回転するように設定されている。各スクレーパ２２を回転させる手段としてモータ２４が設けられ、このモータ２４にスプロケットホイール２６を取り付けるとともに、回転軸１８にスプロケットホイール２８を取り付け、各スプロケットホイール２６、２８には回転伝達手段としてチェーン３０が懸け回されている。したがって、モータ２４の正逆転回転が回転軸１８に伝達され、スクレーパ２２を矢印Ｎで示す任意の方向に所定時間毎に一定の角度回転や単位回転、或いは間欠回転等の様々な回転形態を以て回転させることができる。
【００２１】
容器２の上部には、容器２内で発生する水蒸気３を外部に導く送気口３２が形成されるとともに、処理後の空気を容器２内に導く吸気口３４が形成され、送気口３２と吸気口３４との間には循環路３６が形成されている。即ち、容器２と循環路３６とは一定の密閉空間を形成している。
【００２２】
送気口３２には、吸気口３４より広い送気室３８が形成されており、この送気室３８には、圧送手段として循環用ファン４０が設置されている。この循環用ファン４０は、循環路３６外に設置されたファンモータ４２によって回転される。この循環用ファン４０の回転により、容器２内に発生した水蒸気３や空気が矢印ａ、ｂで示す方向に循環路３６に強制的に導かれる。送気室３８の壁面部には温度センサ４４が設けられ、送気室３８内に導かれた水蒸気３等の温度を検出する。
【００２３】
循環路３６には、水蒸気３が持つ熱を放熱、冷却して水を凝縮させる凝縮手段、その凝縮水を分離する分離手段としての放熱器４６が設けられている。放熱器４６は、複数の管路４８と無数の放熱フィン５０とを備えており、この実施形態では空冷式である。そこで、強制的な冷却手段として冷却用ファン５２が設けられ、この冷却用ファン５２はファンモータ５４によって高速回転する。
【００２４】
放熱器４６の出口部には、凝縮水と空気とを分離する手段として気液分離室５６が設けられている。この気液分離室５６には、分離された空気５８を容器２の吸気口３４に導く循環路３６が連結されるとともに、分離された凝縮水６０を循環路３６から外部に排出する排出手段としての排水管６２が連結されている。
【００２５】
この排水管６２には、臭気止めとして管路を屈曲させて形成した臭気トラップ６４が設けられている。即ち、臭気トラップ６４は、排水管６２の一部又は他の管路で形成され、下に凸を成す半円状の屈曲部６６と、上に凸を成す半円状の屈曲部６８を上下方向に所定間隔を設けて形成したものである。気液分離室５６からの凝縮水６０は、重力によって屈曲部６６側に屈曲部６８を越えない程度の所定量を滞留させることにより、循環路３６に作用する圧力に応じて臭気止めを構成している。したがって、凝縮水６０は、臭気トラップ６４を通して矢印ｃ方向に排出される。
【００２６】
次に、図２は、生ごみ処理の制御装置を示している。制御演算装置７０は、プログラムを実行して所定の制御を行うＣＰＵ７２、動作プログラム、データを記憶するＲＯＭ７４、演算における一時記憶を行うためのＲＡＭ７６、Ａ／Ｄ変換器７８、入力インターフェイス８０、出力インターフェイス８２等を備えている。Ａ／Ｄ変換器７８には電圧増幅器等から構成される検出回路８４が接続され、温度センサ１６、４４の検出信号がこの検出回路８４を通して加えられる。入力インターフェイス８０には、電圧増幅器等から構成される検出回路８６が接続され、スイッチ１２及び運転スイッチ８８の開閉信号がこの検出回路８６を通して加えられる。運転スイッチ８８は生ごみ処理動作を開始させるスイッチである。また、出力インターフェイス８２には駆動回路９０を介してヒータ１４、モータ２４、ファンモータ４２、５４及び表示器９２が接続されている。表示器９２はＬＥＤ、ＬＣＤ、蛍光表示器等からなる視覚的表示器、スピーカ、ブザー等の聴覚的表示器で構成することができ、必要な表示や警報を聴覚的又は視覚的に表示し、使用者に告知することができる。
【００２７】
次に、図３に示す動作フローチャートに従って動作を説明する。
【００２８】
ステップＳ１は、生ごみ処理の前段階処理及び運転開始を示している。容器２に蓋８を開いて処理すべき生ごみ４を入れ、運転スイッチ８８を投入する。蓋８の開閉は、スイッチ１２によって検出される。この検出信号は、検出回路８６を通して入力インターフェイス８０から、閉情報又は開情報としてＣＰＵ７２に加えられる。蓋８が閉じられたことをスイッチ１２が検知すると、ステップＳ２に移行する。
【００２９】
ステップＳ２では、運転スイッチ８８の投入及び蓋８の閉成を条件として乾燥処理に入る。即ち、ステップＳ２では、ヒータ１４の駆動及びその温度制御が開始され、モータ２４及びファンモータ４２、５４が動作を開始し、容器２内に発生する水蒸気３の循環及び放熱が開始される。このとき、モータ２４の回転によりスクレーパ２２が回動し、容器２内の生ごみ４の攪拌とともに容器２底面に付着する生ごみ４を掻き取る。
【００３０】
このような動作が連続的に行われると、容器２及び循環路３６内の雰囲気温度が平衡状態となり、生ごみ４から水蒸気３の発生が活発となる。即ち、水蒸気３は、循環用ファン４０によって放熱器４６に導かれて放熱、冷却され、水蒸気３は凝縮し、空気５８と凝縮水６０とに分離、生成される。即ち、生ごみ４の加熱により、水蒸気３の熱量をＱ₀とし、放熱器４６で放熱される熱量をＱ₁とすると、容器２には、両者の差である熱量（Ｑ₀−Ｑ₁）が帰還される。そして、凝縮水６０は臭気トラップ６４に滞留し、容器２側と外気に通ずる排水管６２とを遮断する。この結果、外気への臭気発散が防止される。
【００３１】
ステップＳ３では、平衡状態であった雰囲気温度が上昇に転じ、所定温度を越えたか否かを監視する。雰囲気温度が上昇した場合、生ごみ４の水分が蒸発したものと判定され（乾燥処理の完了）、ステップＳ４に移行する。
【００３２】
ステップＳ４では、乾燥処理の終了としてヒータ１４の通電を停止し、ステップＳ５に移行する。ステップＳ５は、容器２内の冷却処理ルーチンである。即ち、ファンモータ４２、５４の回転動作を継続し、空気５８の循環を通して容器２内の雰囲気温度を低下させる。この空気循環は、所定時間だけ行うか、又は、雰囲気温度が所定温度に低下するまで行う。この結果、雰囲気温度が低下することにより、容器２及び循環路３６で構成される密閉空間内の圧力を減少させることができ、蓋８の開成時に水蒸気の漏出を抑制できる。
【００３３】
そして、ステップＳ５では、容器２内の雰囲気温度が所定温度まで低下したか否かを判定し、雰囲気温度が所定温度に低下するまで、ファンモータ４２、５４の回転動作を継続し、雰囲気温度が所定温度まで低下したとき、ステップＳ６に移行する。
【００３４】
ステップＳ６では、雰囲気温度の低下に基づき、モータ２４及びファンモータ４２、５４の動作を停止した後、ステップＳ７に移行し、生ごみ４の乾燥処理及び取出し可能状態になったことを表示器９２により報知する。
【００３５】
使用者は、容器２の蓋８を開いて乾燥処理されたごみを取り出し、廃棄することができる。この場合、運転スイッチ８８の投入状態に関係なく、蓋８が開かれると、その開情報がＣＰＵ７２に加えられ、回転動作や加熱動作の総てが停止状態に保持され、高度な安全対策が施されている。
【００３６】
次に、図４は、容器２内の雰囲気温度ＣＴとヒータ１４の表面温度ＨＴの推移を示し、横軸は時間ｔ（分）、縦軸は温度Ｔ（℃）である。
【００３７】
区間ｔ_A（＝ｔ₀〜ｔ₁）は、ヒータ１４の加熱で生ごみ４中の水分が沸点に到達する前の容器２内の雰囲気温度の温度上昇を示し、この区間ｔ_Aでは、水蒸気３の発生開始による膨張圧力が増大し、その圧力により、凝縮水６０及び空気５８の一部が排水管６２を通じて外部に排出される。このとき、悪臭を放つことはない。放熱器４６で放熱されて凝縮水６０が分離された空気５８は循環路３６を通じて容器２内に帰還され、容器２内の空気と混合される。
【００３８】
区間ｔ_B（＝ｔ₁〜ｔ₂）は、生ごみ４中の水分が沸点に到達し、雰囲気温度が平衡状態になる。このとき、水蒸気３の加熱による膨張と冷却による収縮とが行われ、即ち、水蒸気３の発生及びその凝縮が連続的に進行し、外気圧と内圧とが略等しい状態となる。凝縮水６０は、再び臭気トラップ６４に滞留して排気管６２を遮断する。この結果、水蒸気３の発生が活発な温度領域では、その水蒸気３が容器２内に封じ込められ、外部への漏洩が抑制される。この結果、水蒸気３の放出により周囲環境を害することはない。
【００３９】
そして、生ごみ４中の水分が蒸発すると、容器２内の雰囲気温度は再び上昇を開始し、その雰囲気温度が所定温度ＨＯを越えるとき、ヒータ１４の通電を停止する。また、平衡温度から所定温度上昇した時点において、ヒータ１４の通電を停止させるようにしても良い。
【００４０】
また、容器２内の平衡温度から温度が上昇に転じることにより、容器２内の圧力が上昇を開始するため、ヒータ１４を停止させて圧力上昇を抑制する。所定時間ファンモータ４２、５４の動作を継続させて、容器２内の雰囲気温度を外部に放出させて冷却し、水蒸気３の圧力を低下させる。この結果、蓋８を開成したときに、外部に水蒸気３の放出を抑制できる。また、温度センサ４４によって温度を検知することにより、雰囲気温度が所定温度に低下したとき、ファンモータ４２、５４の駆動を停止させるようにしても良い。
【００４１】
【発明の効果】
以上説明したように、本発明によれば、次のような効果が得られる。
ａ．生ごみの加熱処理による乾燥処理ができるとともに、加熱によって生じた水蒸気を冷却により凝縮させ、水蒸気から水を分離し、容器内の圧力状態に応じて外部に排出するので、容器と外気とを確実に分離遮断し、悪臭の原因となる水蒸気等のガスの漏洩を防止できる。
ｂ．生ごみの加熱処理の後、十分に冷却した容器から処理ごみを取り出すことができるので、加熱処理で生じた水蒸気の漏洩を確実に低減でき、悪臭による環境汚染を防止できる。
ｃ．生ごみを熱収縮による乾燥処理されたごみは生ごみに比較して大幅に容積が小さく、その廃棄処理が容易となり、肥料等への再利用が期待できる。

BACKGROUND OF THE INVENTION
The present invention relates to a garbage processing apparatus that processes food waste, represented by vegetables such as vegetables, seafood, and the like.
[0002]
[Prior art]
Garbage such as garbage is not suitable for ordinary incineration processing because it contains a lot of moisture, and disposal processing is generally troublesome. This is because a large amount of water contained in garbage reduces incineration efficiency. Garbage dumping causes environmental pollution. In addition, although there is a diversion of raw garbage to fertilizer, untreated raw garbage cannot be used as it is as fertilizer.
[0003]
[Problems to be solved by the invention]
Conventionally, heat treatment of garbage has been proposed, but the release of water vapor generated by heating to the outside air causes bad odor. Therefore, deodorizing treatment is required, but conventionally, there are methods such as a catalyst method and an activated carbon method. In the catalyst system, in order to obtain a sufficient deodorizing effect, it is necessary to keep the catalyst at a high temperature of 200 to 400 ° C., and further, it is necessary to increase the wind speed through which the catalyst passes, and thus heating is troublesome. It is not suitable for home use. Moreover, since various odors are mixed in water vapor, the activated carbon method may not provide a deodorizing effect. Moreover, since activated carbon absorbs odorous particles, its saturation reduces the deodorizing effect and needs to be replaced periodically. As other methods, ozone deodorization, platinum deodorization, bio deodorization, and the like have been proposed, but it is difficult to completely remove bad odors.
[0004]
Then, an object of this invention is to provide the garbage processing apparatus which implement | achieved the simplification of the disposal process of garbage by simple drying process.

Separation means (radiator 46, gas-liquid separation chamber 56) for returning air to the container after condensing (condensed water 60), and the pressure at which the water condensed and separated from water vapor acts in the container Correspondingly, a discharge means (drain pipe 62) for discharging to the outside of the container is provided, the water vapor generated from the garbage is circulated and cooled by heating, separated into air and water, the container and the circulation system are decompressed, and the container The internal pressure is maintained at a constant level, and the waste is not brominated, and the waste is reduced by drying, thereby facilitating the disposal of garbage.

The user can be notified.
[0027]
Next, the operation will be described according to the operation flowchart shown in FIG.
[0028]
Step S1 shows the pre-stage process and the operation start of the garbage process. The lid 8 is opened in the container 2 and the garbage 4 to be processed is put in, and the operation switch 88 is turned on. Opening / closing of the lid 8 is detected by the switch 12. This detection signal is applied from the input interface 80 through the detection circuit 86 to the CPU 72 as closing information or opening information. When the switch 12 detects that the lid 8 is closed, the process proceeds to step S2.
[0029]
In step S2, the drying process is started on condition that the operation switch 88 is turned on and the lid 8 is closed. That is, in step S2, the driving of the heater 14 and the temperature control thereof are started, the motor 24 and the fan motors 42 and 54 start operating, and the circulation and heat dissipation of the water vapor 3 generated in the container 2 is started. At this time, the scraper 22 is rotated by the rotation of the motor 24, and the garbage 4 adhering to the bottom surface of the container 2 is scraped off with the stirring of the garbage 4 in the container 2.
[0030]
When such an operation is continuously performed, the atmospheric temperature in the container 2 and the circulation path 36 becomes an equilibrium state, and the generation of water vapor 3 from the garbage 4 becomes active. That is, the water vapor 3 is guided to the radiator 46 by the circulation fan 40 to be radiated and cooled, and the water vapor 3 is condensed and separated into air 58 and condensed water 60 and generated. That is, if the amount of heat of the steam 3 is Q ₀ and the amount of heat radiated by the radiator 46 is Q ₁ by heating the garbage 4, the container 2 has a heat amount (Q ₀ -Q ₁ ) which is the difference between the two. Will be returned. The condensed water 60 stays in the odor trap 64 and shuts off the container 2 side and the drain pipe 62 communicating with the outside air. As a result, odor emission to the outside air is prevented.
[0031]
In step S3, it is monitored whether the atmospheric temperature in the equilibrium state has started to rise and has exceeded a predetermined temperature. When the atmospheric temperature rises, it is determined that the moisture in the garbage 4 has evaporated (drying process is completed), and the process proceeds to step S4.
[0032]
In step S4, energization of the heater 14 is stopped at the end of the drying process, and the process proceeds to step S5. Step S <b> 5 is a cooling processing routine in the container 2. That is, the rotation operation of the fan motors 42 and 54 is continued, and the atmospheric temperature in the container 2 is lowered through the circulation of the air 58. This air circulation is performed for a predetermined time or until the ambient temperature is lowered to a predetermined temperature. As a result, when the atmospheric temperature is lowered, the pressure in the sealed space formed by the container 2 and the circulation path 36 can be reduced, and leakage of water vapor can be suppressed when the lid 8 is opened.
[0033]
In step S5, it is determined whether or not the atmospheric temperature in the container 2 has decreased to a predetermined temperature, and the fan motors 42 and 54 are continuously rotated until the atmospheric temperature decreases to the predetermined temperature. When the temperature falls to the predetermined temperature, the process proceeds to step S6.
[0034]
In step S6, the operation of the motor 24 and the fan motors 42 and 54 is stopped based on the decrease in the ambient temperature, and then the process proceeds to step S7, where the display 92 indicates that the garbage 4 is ready for drying and removal. To inform.
[0035]
The user can open the lid 8 of the container 2 to take out the dried waste and discard it. In this case, regardless of the operating state of the operation switch 88, when the lid 8 is opened, the opening information is added to the CPU 72, and all rotation and heating operations are held in a stopped state, and advanced safety measures are taken. Has been.
[0036]
Next, FIG. 4 shows the transition of the ambient temperature CT in the container 2 and the surface temperature HT of the heater 14, where the horizontal axis is time t (minutes) and the vertical axis is temperature T (° C.).
[0037]
Interval _{_{_{t A (= t 0 ~t 1}}} ) shows the temperature increase of the ambient temperature before in the vessel 2 the moisture of garbage 4 in the heating of the heater 14 reaches the boiling point, in the section t _A, steam 3 is increased, and the condensed water 60 and a part of the air 58 are discharged to the outside through the drain pipe 62 by the pressure. At this time, no odor is emitted. The air 58 radiated by the radiator 46 and separated from the condensed water 60 is returned to the container 2 through the circulation path 36 and mixed with the air in the container 2.
[0038]
In the section t _B (= t _{1 to} t ₂ ), the moisture in the garbage 4 reaches the boiling point, and the ambient temperature is in an equilibrium state. At this time, expansion by heating of the water vapor 3 and contraction by cooling are performed, that is, generation of the water vapor 3 and its condensation proceed continuously, and the external pressure and the internal pressure become substantially equal. The condensed water 60 stays in the odor trap 64 again and blocks the exhaust pipe 62. As a result, in the temperature range where the generation of the water vapor 3 is active, the water vapor 3 is contained in the container 2 and leakage to the outside is suppressed. As a result, the surrounding environment is not harmed by the release of the water vapor 3.
[0039]
And when the water | moisture content in the garbage 4 evaporates, the atmospheric temperature in the container 2 will start rising again, and when the atmospheric temperature exceeds predetermined temperature HO, electricity supply of the heater 14 will be stopped. Further, the energization of the heater 14 may be stopped when a predetermined temperature rises from the equilibrium temperature.
[0040]
Further, since the pressure in the container 2 starts to rise when the temperature starts to rise from the equilibrium temperature in the container 2, the heater 14 is stopped to suppress the pressure rise. The operation of the fan motors 42 and 54 is continued for a predetermined time, the ambient temperature in the container 2 is discharged to the outside, and the pressure of the water vapor 3 is reduced. As a result, when the lid 8 is opened, the release of the water vapor 3 can be suppressed. Further, by detecting the temperature by the temperature sensor 44, the driving of the fan motors 42 and 54 may be stopped when the ambient temperature is lowered to a predetermined temperature.
[0041]
【The invention's effect】
As described above, according to the present invention, the following effects can be obtained.
a. In addition to being able to dry the garbage by heat treatment, water vapor generated by heating is condensed by cooling, water is separated from the water vapor, and discharged to the outside according to the pressure state in the container. It is possible to prevent leakage of gas such as water vapor that causes bad odor.
b. After the heat treatment of the garbage, the treated waste can be taken out from the sufficiently cooled container, so that leakage of water vapor generated by the heat treatment can be surely reduced and environmental pollution due to bad odor can be prevented.
