Abstract

<P>PROBLEM TO BE SOLVED: To provide a trash compactor easy in operation, and setting a compacting end position of a compacting member as desired. <P>SOLUTION: In this trash compactor, an electric motor 20 is rotated normally and reversely to move the compacting member 2 to a stand-by position and a compacting position. The electric motor 20 is provided with a rotation direction control part 31 to produce normal rotation and reverse rotation by a main coil 30 and the direction of current flowing in it. As the compacting member 2 is at the stand-by position, with a start switch 45 ON, the electric motor 20 is rotated normally to move the compacting member 2 in a compacting direction. When it is moved for prescribed strokes, the rotation direction control part 31 makes reverse rotation, while without any supply of current, normal rotation is continued. When the compacting member 2 compacts trash, the electric motor 20 stops. As the current is supplied to the rotation direction control part 31, the compacting member 2 starts reverse rotation to move toward the stand-by position. <P>COPYRIGHT: (C)2004,JPO

Description

【０００１】
【発明の属する技術分野】
本発明は、主として家庭の台所で使用するゴミ圧縮機に関する。
【０００２】
【従来の技術】
家庭から種々のゴミが発生し、そのゴミの回収、処理が社会問題となっている。
このことから、家庭から発生する缶・ペットボトルなどのゴミを圧縮して容積を小さくするゴミ圧縮機が種々提案されている。
例えば、特開平７−１１２２９９号公報に、電動モータでスクリュー軸を回転することで可動板（つまり、圧縮部材）を移動し、受止板上に置いた缶を圧縮するゴミ圧縮機が開示されている。
【０００３】
【発明が解決しようとする課題】
前述の電動モータで可動板を移動するゴミ圧縮機は、その可動板の上限を検出して電動モータを停止する上限リミットスイッチと、下限を検出して電動モータを停止する下限リミットスイッチと、電動モータを逆転して可動板を下降する下降スイッチと、電動モータを正転して可動板を上昇する上昇スイッチを備え、その下降スイッチ、上昇スイッチを操作して可動板を上下に移動している。
このために、可動板を上下に移動するために２つのリミットスイッチと２つのスイッチが必要で、電気部品点数が多く、コストが高くなると共に、配線が複雑となる。
また、下降スイッチと上昇スイッチを操作するので、その操作が面倒である。
【０００４】
さらに、可動板の下限を下限リミットスイッチで検出して電動モータを停止することで下限位置に停止するので、その可動板の下限位置（つまり、圧縮終了位置）が一定である。
このために、可動板で缶を圧縮した後に、その圧縮した缶の上に新たに缶を置いて圧縮しようとすると、可動板が前述の圧縮終了位置まで下降しないから下限リミットスイッチで可動板を検出できない。このようにする場合には複数の下限リミットスイッチを設けることになる。
【０００５】
本発明は前述の課題に鑑みなされたものであり、その目的は、少ない電気部品点数で圧縮部材を移動できると共に、操作が簡単であり、しかも圧縮終了位置を任意とすることができるゴミ圧縮機を提供することである。
【０００６】
【課題を解決するための手段】
第１の発明は、機体１と、圧縮部材２と、この圧縮部材２を待機位置と圧縮位置とに亘って移動する移動装置３と、前記圧縮部材２と対向したゴミ受け部４を備え、
前記移動装置３は電動モータ２０を正回転することで圧縮部材２を圧縮位置に向けて移動し、逆回転することで圧縮部材２を待機位置に向けて移動する形態で、
前記電動モータ２０は、正回転状態と逆回転状態に切換可能で、かつ状態を切換えても回転している時には回転方向が変化せずに停止した時に回転方向が変化するモータで、
前記圧縮部材２が待機位置において起動操作することで電動モータ２０が正回転状態となると共に、通電開始し、その圧縮部材２が所定ストローク圧縮方向に移動すると逆回転状態に切換え、圧縮部材２が再び待機位置となると電動モータ２０への通電を中止するようにしたことを特徴とするゴミ圧縮機である。
【０００７】
第２の発明は、第１の発明において電動モータ２０は正回転する第１の結線と逆回転する第２の結線に切換え可能とし、
圧縮部材２が待機位置であること及び待機位置の圧縮部材２が所定ストローク圧縮方向に移動したことを検出する検出手段と、
電動モータ２０の結線を切換える結線切換手段と、
起動信号を出力する起動信号出力手段を設け、
圧縮部材２が待機位置である第１の検出信号と起動信号で電動モータ２０を第１の結線として通電し、待機位置の圧縮部材２が所定ストローク圧縮方向に移動した第２の検出信号で第２の結線に切換え、
第２の検出信号の後に第１の検出信号によって電動モータ２０への通電を中止するようにしたゴミ圧縮機である。
【０００８】
第３の発明は、第２の発明において電動モータ２０は通電することで回転する主コイル３０と回転方向を決める回転方向制御部３１を備え、この回転方向制御部３１に一方向に電流が流れると正回転、他方向に電流が流れると逆回転で、前記回転方向制御部３１は回転している時には電流が流れずに停止すると流れるもので、
起動信号で主コイル３０に通電され、
結線切換手段は起動信号と第１の検出信号で回転方向制御部３１に一方向に電流が流れる第１の結線とし、第２の検出信号で回転方向制御部３１に他方向に電流が流れる第２の結線とし、
第１の検出信号で主コイル３０への通電が中止されるようにしたゴミ圧縮機である。
【０００９】
第４の発明は、第１又は第２又は第３の発明においてゴミ受け部４は上面が開口した箱形状の第１ゴミ受け部１１と、この第１ゴミ受け部１１の上面を覆う第１位置と解放する第２位置に移動可能な第２ゴミ受け部１２を備えているゴミ圧縮機である。
【００１０】
【作　用】
第１の発明によれば、圧縮部材２が待機位置で起動操作すると電動モータ２０が正回転して圧縮方向に移動し、所定ストローク移動すると電動モータ２０は逆回転する状態となるが電動モータ２０は回転しているから正転し続ける。
そして、圧縮部材２がゴミ受け部４上のゴミを圧縮すると電動モータ２０が停止し、その電動モータ２０は直ちに逆回転して圧縮部材２は待機位置に向けて移動する。
圧縮部材２が待機位置まで移動すると電動モータ２０が停止して圧縮部材２が待機位置で停止する。
このように、圧縮部材２がゴミを圧縮して電動モータ２０が停止することで電動モータ２０が逆回転して圧縮部材２を待機位置に向けて移動するから、圧縮部材２がゴミを圧縮した位置をリミットスイッチ等で検出し、再び電動モータ２０に起動信号を入力する必要がなく、電気部品点数を少なくできると共に、操作が簡単である。
しかも、ゴミを圧縮して電動モータ２０が停止したら電動モータ２０が逆回転するから、そのゴミを圧縮した位置、つまり圧縮終了位置は任意である。
したがって、少ない電気部品点数で圧縮部材２を移動できると共に、操作が簡単であり、しかも圧縮終了位置を任意とすることができる。
【００１１】
第２の発明によれば、検出手段と、結線切換手段と、起動信号出力手段を設けることで圧縮部材２を移動できると共に、圧縮終了位置を任意にできる。
また、起動信号出力手段から起動信号を入力するだけであるから、操作が簡単である。
【００１２】
第４の発明によれば、第２ゴミ受け部１２を第２位置とすることで、第１ゴミ受け部１１のゴミを圧縮できる。
しかも、この第１ゴミ受け部１１は上面が開口した箱形状であるから、第１ゴミ受け部１１に一般ゴミを入れ、満杯となったら圧縮して容積を小さくして再び一般ゴミを入れることができる。
よって、第１ゴミ受け部１１を一般ゴミを入れるゴミ箱として利用できるし、その第１ゴミ受け部１１内の一般ゴミを何回も圧縮する時に圧縮部材２の圧縮終了位置が任意であるから効率良く圧縮できる。
また、第２ゴミ受け部１２を第１位置とすることで、その第２ゴミ受け部１２上のゴミ、例えば缶、ペットボトルなどを圧縮できる。
【００１３】
【発明の実施の形態】
図１に示すように、機体１と、この機体１に待機位置と圧縮位置とに亘って移動自在に設けた圧縮部材２と、この圧縮部材２を移動する移動装置３と、圧縮するゴミを置くゴミ受け部４でゴミ圧縮機を構成している。
【００１４】
この実施の形態では、機体１は底板１ａと天板１ｂと左右の側面板１ｃと後面板１ｄで前面に開口部１ｅを有する箱形状である。
前記圧縮部材２は上面が開口した箱形状である。この圧縮部材２は上下に移動する。
前記ゴミ受け部４は、前記開口部１ｅを開閉する扉１０に取付けた第１ゴミ受け部１１と第２ゴミ受け部１２を備えている。
前記第１ゴミ受け部１１は上面１１ａが開口した箱形状で一般ゴミの圧縮に用いられる。この第１ゴミ受け部１１は扉１０の裏面下部寄りに固着してある。
前記第２ゴミ受け部１２は第１ゴミ受け部１１の上面１１ａを覆う第１位置と解放する第２位置に亘って移動自在に取付けてある。
詳しくは、第２ゴミ受け部１２は扉１０の裏面における第１ゴミ受け部１１よりも上方寄りにヒンジ１３で上下回動自在に取付けられ、下方に回動すると第１ゴミ受け部１１の上面１１ａに接する横向姿勢、つまり第１位置となる。上方に回動すると扉１０の裏面に沿った縦向姿勢、つまり第２位置となると共に、保持手段、例えば係止片１４で保持される。１５は把手である。
前記扉１０はガイド１６で機体１に引き出し、押し込み自在に取付けられる。
【００１５】
このようであるから、第２ゴミ受け部１２を第２位置として扉１０を押し込むと図２に示すように第１ゴミ受け部１１が圧縮部材２と対向したゴミ圧縮位置となると共に、開口部１ｅが扉１０で閉じられる。
前述の状態で扉１０を引き出すことで第１ゴミ受け部１１が図１に示すように機体１の前面から突出し、その第１ゴミ受け部１１に一般ゴミを入れることができると共に、圧縮した一般ゴミを取り出しできる。
第２ゴミ受け部１２を第１位置として扉１０を押し込むと図３に示すように第２ゴミ受け部１２が圧縮部材２と対向したゴミ圧縮位置となると共に、開口部１ｅが扉１０で閉じられる。
前述の状態で扉１０を引き出すことで第２ゴミ受け部１２が機体１の表面から突出し、その第２ゴミ受け部１２に缶・ペットボトルａなどを置くことができると共に、仮想線で示すように圧縮した缶・ペットボトルａなどを取り出しできる。
【００１６】
前記機体１、圧縮部材２、ゴミ受け部４は前述の形態に限ることはなく、ゴミ受け部４は圧縮部材２と対向したゴミ圧縮位置に取付けても良い。
また、圧縮部材２は上下に移動するのではなく、左右に移動するものでも良い。
【００１７】
前記移動装置３はこの実施の形態では、電動モータ２０と、この電動モータ２０で回転されるねじ杆（台形ねじ杆）２１と、圧縮部材２に固着したナット２２を備え、電動モータ２０でねじ杆２１を正・逆回転することで圧縮部材２が待機位置と圧縮位置とに亘って移動する。この実施の形態では圧縮部材２は上下に移動し上限位置が待機位置で、下降位置が圧縮位置である。
【００１８】
詳しくは、電動モータ２０で回転される第１ギヤ２３に第２ギヤ２４が噛合し、この第２ギヤ２４に設けた第１スプロケット２５とねじ杆２１に設けた第２スプロケット２６にチェーン２７が巻掛けてある。
前記ねじ杆２１は底板１ａと天板１ｂに回転自在に支承され、そのねじ杆２１の下部に筒２８が嵌合してあり、この筒２８は底板１ａに軸受２９で回転自在に支承され、後述するようにゴミが無い場合に圧縮部材２の下限を規制するストッパを構成している。
前記ねじ杆２１の下部を底板１ａに回転自在に取付け、圧縮部材２にステーを介してナット２２を吊り下げるように取付け、このナット２２にねじ杆２１の上部をねじ合するようにしても良い。
【００１９】
前記移動装置３は、電動モータ２０でナット２２を回転させる形態でも良いし、電動モータ２０でピニオンを回転し、このピニオンを圧縮部材２に取付けたラックに噛合した構成でも良い。
つまり、移動装置３は電動モータ２０を正回転することで圧縮部材２を圧縮位置に向けて移動し、逆回転することで圧縮部材２を待機位置に向けて移動する形態であれば良い。
【００２０】
次に、前記電動モータ２０を正回転、逆回転して圧縮部材２を移動制御する装置について説明する。
前記電動モータ２０は正回転状態と逆回転状態に切換可能で、かつ状態を切換えても回転している時には回転方向が変化せずに停止した時に回転方向が変化するモータである。前述の停止とは定常速度よりも低速回転の場合と完全に停止した場合を含む。
例えば、電動モータ２０は図４に示すように、正回転する第１の結線と逆回転する第２の接線に切換え可能で、その結線を切換えても電動モータ２０が回転している時には回転方向が変化せずに、電動モータ２０が停止すると回転方向が変化するコンデンサ始動電動モータである。前述の結線とは電動モータ２０の端子と電源の接続の仕方である。
【００２１】
具体的には、電動モータ２０は主コイル３０に電流が流れると回転し、回転方向制御部３１、例えば直列接続された補助コイル３２、始動スイッチ３３、コンデンサ３４に流れる電流の向きで回転方向が決定する。
前記主コイル３０は第１端子３５と第２端子３６に接続し、回転方向制御部３１は第３端子３７と第４端子３８に接続している。
そして、第３端子３７から第４端子３８に電流が流れると正回転し、第４端子３８から第３端子３７に電流が流れると逆回転する。
【００２２】
前記第１〜第４端子３５〜３８と電源３９を接続する電気回路には結線切換手段と起動信号出力手段と検出手段が設けてある。
前記結線切換手段はリレー４０、このリレー４０の第１・第２リレー接点４１，４２を備え、リレー４０に通電されない時には第１の結線、リレー４０に通電されると第２の結線に切換える。
第１の結線の時は第３端子３７から第４端子３８に向けて電流が流れて正回転し、第２の結線の時は第４端子３８から第３端子３７に向けて電流が流れて逆回転する。
前記第１・第２リレー接点４１，４２はリレー４０に通電されない時には閉（ＮＣ）、通電されると開（ＮＯ）となる常閉接点である。
図に示すリレー４０は第３リレー接点４３を備え、この第３リレー接点４３は常開接点である。
前記起動信号出力手段は電源スイッチ４４とスタートスイッチ４５である。
前記電源スイッチ４４は一度ＯＮするとＯＮし続け、ＯＦＦするとＯＦＦし続ける。
前記スタートスイッチ４５は常時ＯＦＦで、ＯＮ操作したときにのみＯＮとなる。
【００２３】
前記検出手段は、圧縮部材２が待機位置であることを検出して第１の信号を出力し、待機位置の圧縮部材２が所定ストローク圧縮方向に移動したことを検出して第２の信号を出力する。
例えば、図２に示すように機体１にリミットスイッチ４６を取付け、その可動片４６ａを圧縮部材２と対向させる。
圧縮部材２が待機位置であると可動片４６ａが押されてリミットスイッチ４６がＯＦＦし、圧縮部材２が待機位置から圧縮方向に所定ストローク移動すると可動片４６ａが元の位置に復帰してリミットスイッチ４６がＯＮする。
よって、リミットスイッチ４６がＯＮからＯＦＦとなったことで圧縮部材２が待機位置であることを検出でき、リミットスイッチ４６がＯＦＦからＯＮすることで圧縮部材２が待機位置から圧縮方向に所定ストローク移動したことを検出できる。
【００２４】
次に、作動とともに各部材の詳細を説明する。
圧縮部材２が待機位置で停止している時にはリミットスイッチ４６がＯＦＦで、電源スイッチ４４、スタートスイッチ４５はＯＦＦである。
よって、リレー４０には通電されずに第３リレー接点（常開接点）４３は開で、第１・第２リレー接点（常閉接点）４１，４２は閉（ＮＣ）であるから第３端子３７は第２リレー接点４２、スタートスイッチ４５、電源スイッチ４４を経て電源３９の一方側に接続し、第４端子３８は第１リレー接点４１を経て電源３９の他方側に接続して前述の第１の結線である。
【００２５】
前述の状態で電源スイッチ４４とスタートスイッチ４５をＯＮ、つまり起動信号を出力すると第１端子３５と第２端子３６に電流が流れると共に、第３端子３７から第４端子３８に電流が流れ、電動モータ２０が正回転して圧縮部材２が圧縮位置に向けて移動する。
所定ストローク移動するとリミットスイッチ４６がＯＮし、リレー４０に通電され、第３リレー接点４３が閉となると共に、第１・第２リレー接点４１，４２が開（ＮＯ）となる。
これによって、スタートスイッチ４５をＯＦＦしてもリレー４０の第３リレー接点４３を経て電流が流れ続ける。電動モータ２０の第３端子３７が第２リレー接点４２、第１リレー接点４１を経て電源３９の他方側に接続し、第４端子３８が第１リレー接点４１、第２リレー接点４２、第３リレー接点４３、電源スイッチ４４を経て電源３９の一方側に接続して第２の結線となる。
【００２６】
電動モータ２０が定常速度で回転しているので、遠心力で始動スイッチ３３がＯＦＦし、回転方向制御部３１に電流が流れないので、電動モータ２０は正回転のままで、圧縮部材２は圧縮位置に向けて移動し、ゴミ受け部４に置かれたゴミを圧縮開始し、ある程度まで圧縮すると圧縮部材２の移動抵抗が大きくなって電動モータ２０の回転が遅くなり、最終的に停止する。
これにより、始動スイッチ３３がＯＮして回転方向制御部３１に電流が流れ、電動モータ２０は直ちに逆回転し、圧縮部材２は待機位置に向けて移動する。
圧縮部材２が待機位置となるとリミットスイッチ４６がＯＦＦし、リレー４０に通電されなくなって第３リレー接点４３が開となって電動モータ２０が停止し、圧縮部材２が待機位置で停止する。
これと同時に第１・第２リレー接点４１，４２が閉となる。
【００２７】
このように、圧縮部材２がゴミを圧縮することで電動モータ２０の回転抵抗が大きくなり、その回転が遅くなって停止することで電動モータ２０が逆回転して圧縮部材２が待機位置に向けて移動するので、圧縮部材２がゴミ圧縮した位置であることを検出するリミットスイッチと電動モータ２０を逆回転させるためのスイッチが不要で電気部品点数を少なくできる。
【００２８】
また、電源スイッチ４４とスタートスイッチ４５をＯＮすれば良く、操作が簡単である。
【００２９】
また、圧縮部材２の圧縮終了位置を任意とすることができる。例えば、図２に示すように第１ゴミ受け部１１で一般ゴミを圧縮する際には圧縮終了位置が下方で、図３に示すように第２ゴミ受け部１２で缶、ペットボトル等を圧縮する際には圧縮終了位置が上方である。
【００３０】
図１〜図３に示す実施の形態では、第２ゴミ受け部１２を第２位置として第１ゴミ受け部１１内にゴミが収納されていない状態で圧縮部材２が下降すると図２に仮想線で示すようにナット２２が筒２８に当接する。
これによって、圧縮部材２の最下限位置を規定し、機体１が破損等しないように保護する。
【００３１】
前記電動モータ２０は図４に示すものに限ることはなく、例えば、図４におけるコンデンサ３４が無い回転方向制御部を有する分相始動電動モータなどでも良い。
前記検出手段は圧縮部材２の待機位置で作動するリミットスイッチと圧縮方向に所定ストローク移動したことで作動するリミットスイッチで構成しても良い。
前記結線切換手段は複数のスイッチを組み合わせたものでも良い。
前記起動信号出力手段は電源スイッチ４４又はスタートスイッチ４５のみでも良い。
また、検出手段の検出信号、起動信号をコントローラに入力し、そのコントローラが電動モータ２０の回転方向を制御するようにしても良い。
【００３２】
【発明の効果】
請求項１に係る発明によれば、圧縮部材２が待機位置で起動操作すると電動モータ２０が正回転して圧縮方向に移動し、所定ストローク移動すると電動モータ２０は逆回転する状態となるが電動モータ２０は回転しているから正転し続ける。
そして、圧縮部材２がゴミ受け部４上のゴミを圧縮すると電動モータ２０が停止し、その電動モータ２０は直ちに逆回転して圧縮部材２は待機位置に向けて移動する。
圧縮部材２が待機位置まで移動すると電動モータ２０が停止して圧縮部材２が待機位置で停止する。
このように、圧縮部材２がゴミを圧縮して電動モータ２０が停止することで電動モータ２０が逆回転して圧縮部材２を待機位置に向けて移動するから、圧縮部材２がゴミを圧縮した位置をリミットスイッチ等で検出し、再び電動モータ２０に起動信号を入力する必要がなく、電気部品点数を少なくできると共に、操作が簡単である。
しかも、ゴミを圧縮して電動モータ２０が停止したら電動モータ２０が逆回転するから、そのゴミを圧縮した位置、つまり圧縮終了位置は任意である。
したがって、少ない電気部品点数で圧縮部材２を移動できると共に、操作が簡単であり、しかも圧縮終了位置を任意とすることができる。
【００３３】
請求項２に係る発明によれば、検出手段と、結線切換手段と、起動信号出力手段を設けることで圧縮部材２を移動できると共に、圧縮終了位置を任意にできる。
また、起動信号出力手段から起動信号を入力するだけであるから、操作が簡単である。
【００３４】
請求項４に係る発明によれば、第２ゴミ受け部１２を第２位置とすることで、第１ゴミ受け部１１のゴミを圧縮できる。
しかも、この第１ゴミ受け部１１は上面が開口した箱形状であるから、第１ゴミ受け部１１に一般ゴミを入れ、満杯となったら圧縮して容積を小さくして再び一般ゴミを入れることができる。
よって、第１ゴミ受け部１１を一般ゴミを入れるゴミ箱として利用できるし、その第１ゴミ受け部１１内の一般ゴミを何回も圧縮する時に圧縮部材２の圧縮終了位置が任意であるから効率良く圧縮できる。
また、第２ゴミ受け部１２を第１位置とすることで、その第２ゴミ受け部１２上のゴミ、例えば缶、ペットボトルなどを圧縮できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a garbage compressor used mainly in a home kitchen.

[Prior art]
Various garbage is generated from homes, and collection and disposal of the garbage are becoming a social problem.
For this reason, various refuse compressors have been proposed which compress refuse such as cans and PET bottles generated from homes to reduce the volume.

[Problems to be solved by the invention]
The dust compressor that moves the movable plate with the electric motor described above includes an upper limit switch that detects the upper limit of the movable plate and stops the electric motor, a lower limit switch that detects the lower limit and stops the electric motor, and an electric motor. It has a down switch that reverses the motor and lowers the movable plate, and an up switch that rotates the electric motor forward and raises the movable plate. The lower switch and the up switch are operated to move the movable plate up and down. .
For this reason, two limit switches and two switches are required to move the movable plate up and down, which increases the number of electrical components, increases the cost, and complicates the wiring.
Further, since the down switch and the up switch are operated, the operation is troublesome.
[0004]
Furthermore, since the lower limit of the movable plate is detected by the lower limit switch and the electric motor is stopped to stop at the lower limit position, the lower limit position (that is, the compression end position) of the movable plate is constant.
For this reason, after compressing the can with the movable plate, if a new can is placed on the compressed can and compression is attempted, the movable plate does not descend to the above-mentioned compression end position. Not detectable. In this case, a plurality of lower limit switches are provided.

According to a fourth invention, in the first, second or third invention, the dust receiving portion 4 is a box-shaped first dust receiving portion 11 having an open upper surface, and a first dust covering portion which covers the upper surface of the first dust receiving portion 11. This is a dust compressor including a second dust receiving portion 12 movable to a second position to be released from a position.
[0010]
[Operation]
According to the first invention, when the compression member 2 is started at the standby position, the electric motor 20 rotates forward and moves in the compression direction. When the compression member 2 moves a predetermined stroke, the electric motor 20 rotates in the reverse direction. Keeps rotating forward because it is rotating.
When the compression member 2 compresses dust on the dust receiving portion 4, the electric motor 20 stops, and the electric motor 20 immediately reversely rotates, and the compression member 2 moves toward the standby position.
When the compression member 2 moves to the standby position, the electric motor 20 stops, and the compression member 2 stops at the standby position.
As described above, since the compression member 2 compresses the dust and the electric motor 20 stops, the electric motor 20 rotates in the reverse direction and moves the compression member 2 toward the standby position, so that the compression member 2 compresses the dust. There is no need to detect the position with a limit switch or the like and input a start signal to the electric motor 20 again, so that the number of electrical components can be reduced and the operation is simple.
In addition, since the electric motor 20 rotates in the reverse direction when the dust is compressed and the electric motor 20 is stopped, the position where the dust is compressed, that is, the compression end position is arbitrary.
Therefore, the compression member 2 can be moved with a small number of electric parts, the operation is simple, and the compression end position can be set arbitrarily.
[0011]
According to the second aspect, the compression member 2 can be moved by providing the detection unit, the connection switching unit, and the activation signal output unit, and the compression end position can be set arbitrarily.
In addition, the operation is simple because only the start signal is input from the start signal output means.
[0012]
According to the fourth aspect, by setting the second dust receiving portion 12 to the second position, dust in the first dust receiving portion 11 can be compressed.
Moreover, since the first dust receiving portion 11 has a box shape with an open upper surface, general dust is put into the first dust receiving portion 11, and when the first dust receiving portion 11 becomes full, the first dust receiving portion 11 is compressed to reduce the volume and put the general dust again. Can be.
Therefore, the first dust receiving portion 11 can be used as a trash can for storing general trash, and the compression end position of the compression member 2 is arbitrary when compressing the general trash in the first dust receiving portion 11 many times. Good compression.
Further, by setting the second dust receiving portion 12 at the first position, dust on the second dust receiving portion 12, such as a can or a plastic bottle, can be compressed.

The first dust receiving portion 11 has a box shape with an open upper surface 11a and is used for compressing general dust. The first dust receiving portion 11 is fixed to a lower portion of the rear surface of the door 10.
The second dust receiving portion 12 is movably attached between a first position covering the upper surface 11a of the first dust receiving portion 11 and a second position to be released.
More specifically, the second dust receiving portion 12 is attached to the rear surface of the door 10 so as to be rotatable up and down by a hinge 13 above the first dust receiving portion 11, and when turned downward, the upper surface of the first dust receiving portion 11 is rotated. 11a, the horizontal position, that is, the first position.

Reference numeral 15 denotes a handle.
The door 10 is pulled out to the body 1 by a guide 16 and is attached so as to be able to be pushed in freely.
[0015]
Thus, when the door 10 is pushed in with the second dust receiving portion 12 being in the second position, the first dust receiving portion 11 becomes the dust compressing position facing the compressing member 2 as shown in FIG. 1e is closed by the door 10.

[0016]
The body 1, the compression member 2, and the dust receiving portion 4 are not limited to the above-described embodiments, and the dust receiving portion 4 may be mounted at a dust compression position facing the compression member 2.
Further, the compression member 2 may move right and left instead of moving up and down.
[0017]
In this embodiment, the moving device 3 includes an electric motor 20, a screw rod (trapezoidal screw rod) 21 rotated by the electric motor 20, and a nut 22 fixed to the compression member 2. By rotating the rod 21 forward and backward, the compression member 2 moves between the standby position and the compression position. In this embodiment, the compression member 2 moves up and down, the upper limit position is the standby position, and the lower position is the compression position.
[0018]
Specifically, a second gear 24 meshes with a first gear 23 rotated by the electric motor 20, and a chain 27 is formed on a first sprocket 25 provided on the second gear 24 and a second sprocket 26 provided on the screw rod 21. It is wound.
The screw rod 21 is rotatably supported by the bottom plate 1a and the top plate 1b, and a cylinder 28 is fitted to a lower portion of the screw rod 21. The cylinder 28 is rotatably supported by the bearing 29 on the bottom plate 1a. As will be described later, a stopper is provided which regulates the lower limit of the compression member 2 when there is no dust.
The lower part of the screw rod 21 may be rotatably mounted on the bottom plate 1a, the nut 22 may be mounted on the compression member 2 via a stay so as to be suspended, and the upper part of the screw rod 21 may be screwed onto the nut 22. .
[0019]
The moving device 3 may be configured such that the nut 22 is rotated by the electric motor 20, or the pinion is rotated by the electric motor 20, and the pinion is engaged with a rack attached to the compression member 2.
In other words, the moving device 3 may be configured to move the compression member 2 toward the compression position by rotating the electric motor 20 in the forward direction, and move the compression member 2 toward the standby position by rotating the electric motor 20 in the reverse direction.
[0020]
Next, a device for controlling the movement of the compression member 2 by rotating the electric motor 20 forward and backward will be described.
The electric motor 20 is a motor that can be switched between a forward rotation state and a reverse rotation state, and the rotation direction does not change when rotating, even when the state is switched, and the rotation direction changes when stopped. The above-mentioned stop includes a case where the rotation is lower than the steady speed and a case where the rotation is completely stopped.
For example, as shown in FIG. 4, the electric motor 20 can be switched to a first tangential line which rotates in the reverse direction and a second tangential line which rotates in the reverse direction. Is a capacitor-starting electric motor whose rotation direction changes when the electric motor 20 stops without changing. The above-mentioned connection is a method of connecting the terminal of the electric motor 20 and the power supply.
[0021]
Specifically, the electric motor 20 rotates when a current flows through the main coil 30, and the rotation direction is controlled by the direction of the current flowing through the rotation direction control unit 31, for example, the auxiliary coil 32 connected in series, the start switch 33, and the capacitor 34. decide.
The main coil 30 is connected to a first terminal 35 and a second terminal 36, and the rotation direction controller 31 is connected to a third terminal 37 and a fourth terminal 38.
When a current flows from the third terminal 37 to the fourth terminal 38, the motor rotates forward, and when a current flows from the fourth terminal 38 to the third terminal 37, the motor rotates reversely.
[0022]
The electric circuit connecting the first to fourth terminals 35 to 38 and the power supply 39 is provided with connection switching means, start signal output means, and detection means.
The connection switching means includes a relay 40, and first and second relay contacts 41 and 42 of the relay 40, and switches to the first connection when the relay 40 is not energized, and to the second connection when the relay 40 is energized.
At the time of the first connection, a current flows from the third terminal 37 to the fourth terminal 38 to rotate forward, and at the time of the second connection, a current flows from the fourth terminal 38 to the third terminal 37. Reverse rotation.
The first and second relay contacts 41 and 42 are normally closed contacts that are closed (NC) when the relay 40 is not energized and open (NO) when energized.
The illustrated relay 40 has a third relay contact 43, which is a normally open contact.
The start signal output means is a power switch 44 and a start switch 45.
Once the power switch 44 is turned on, it continues to be turned on, and when it is turned off, it is kept turned off.
The start switch 45 is always OFF, and is turned ON only when an ON operation is performed.
[0023]
The detecting means outputs a first signal by detecting that the compression member 2 is at the standby position, and outputs a second signal by detecting that the compression member 2 at the standby position has moved in the predetermined stroke compression direction. Output.
For example, as shown in FIG. 2, a limit switch 46 is attached to the body 1, and its movable piece 46 a is opposed to the compression member 2.
When the compression member 2 is at the standby position, the movable piece 46a is pushed and the limit switch 46 is turned off. When the compression member 2 moves from the standby position by a predetermined stroke in the compression direction, the movable piece 46a returns to the original position and the limit switch is switched. 46 turns ON.
Therefore, it can be detected that the compression member 2 is at the standby position by turning the limit switch 46 from ON to OFF, and the compression member 2 moves by a predetermined stroke in the compression direction from the standby position by turning the limit switch 46 from OFF to ON. Can be detected.
[0024]
Next, the details of each member together with the operation will be described.
When the compression member 2 is stopped at the standby position, the limit switch 46 is off, and the power switch 44 and the start switch 45 are off.
Therefore, the third relay contact (normally open contact) 43 is open without energizing the relay 40, and the first and second relay contacts (normally closed contacts) 41 and 42 are closed (NC). 37 is connected to one side of a power source 39 via a second relay contact 42, a start switch 45, and a power switch 44, and a fourth terminal 38 is connected to the other side of the power source 39 via a first relay contact 41, and 1 connection.
[0025]
When the power switch 44 and the start switch 45 are turned on in the above-described state, that is, when a start signal is output, a current flows through the first terminal 35 and the second terminal 36, and a current flows from the third terminal 37 to the fourth terminal 38. The motor 20 rotates forward and the compression member 2 moves toward the compression position.
After a predetermined stroke, the limit switch 46 is turned on, the relay 40 is energized, the third relay contact 43 is closed, and the first and second relay contacts 41 and 42 are open (NO).
As a result, even if the start switch 45 is turned off, the current continues to flow through the third relay contact 43 of the relay 40. The third terminal 37 of the electric motor 20 is connected to the other side of the power supply 39 via the second relay contact 42 and the first relay contact 41, and the fourth terminal 38 is connected to the first relay contact 41, the second relay contact 42, the third A second connection is made by connecting to one side of the power supply 39 via the relay contact 43 and the power switch 44.
[0026]
Since the electric motor 20 is rotating at a steady speed, the start switch 33 is turned off by centrifugal force, and no current flows to the rotation direction control unit 31, so that the electric motor 20 remains in the normal rotation and the compression member 2 is compressed. After moving toward the position, the compression of the dust placed on the dust receiving portion 4 is started, and when the dust is compressed to a certain extent, the movement resistance of the compression member 2 increases, the rotation of the electric motor 20 is slowed, and finally stops.
As a result, the start switch 33 is turned on, a current flows through the rotation direction control unit 31, the electric motor 20 immediately rotates in the reverse direction, and the compression member 2 moves toward the standby position.
When the compression member 2 is at the standby position, the limit switch 46 is turned off, the relay 40 is not energized, the third relay contact 43 is opened, the electric motor 20 stops, and the compression member 2 stops at the standby position.
At the same time, the first and second relay contacts 41 and 42 are closed.
[0027]
As described above, the compression resistance of the electric motor 20 increases due to the compression of the dust by the compression member 2, and the rotation of the electric motor 20 is slowed and stopped. Therefore, a limit switch for detecting that the compression member 2 is in the dust-compressed position and a switch for reversely rotating the electric motor 20 are unnecessary, and the number of electric components can be reduced.
[0028]
Further, it is only necessary to turn on the power switch 44 and the start switch 45, and the operation is simple.
[0029]
Further, the compression end position of the compression member 2 can be set arbitrarily. For example, as shown in FIG. 2, when compressing general garbage in the first garbage receiving unit 11, the compression ending position is downward, and as shown in FIG. The compression end position is upward.
[0030]
In the embodiment shown in FIGS. 1 to 3, when the compression member 2 is lowered with the second dust receiving portion 12 being in the second position and dust is not stored in the first dust receiving portion 11, a virtual line shown in FIG. The nut 22 contacts the cylinder 28 as shown by.
Thus, the lowermost position of the compression member 2 is defined, and the body 1 is protected from being damaged.
[0031]
The electric motor 20 is not limited to the one shown in FIG. 4, and may be, for example, a phase-separated starting electric motor having a rotation direction control unit without the condenser 34 in FIG.
The detection means may be constituted by a limit switch that operates at a standby position of the compression member 2 and a limit switch that operates when the compression member 2 moves a predetermined stroke in the compression direction.
The connection switching means may be a combination of a plurality of switches.
The start signal output means may be only the power switch 44 or the start switch 45.
Alternatively, a detection signal and a start signal of the detection means may be input to a controller, and the controller may control the rotation direction of the electric motor 20.
[0032]
【The invention's effect】
According to the first aspect of the present invention, when the compression member 2 is activated at the standby position, the electric motor 20 rotates forward and moves in the compression direction, and when the electric motor 20 moves a predetermined stroke, the electric motor 20 rotates in the reverse direction. The motor 20 keeps rotating forward because it is rotating.
When the compression member 2 compresses dust on the dust receiving portion 4, the electric motor 20 stops, and the electric motor 20 immediately reversely rotates, and the compression member 2 moves toward the standby position.
When the compression member 2 moves to the standby position, the electric motor 20 stops, and the compression member 2 stops at the standby position.
As described above, since the compression member 2 compresses the dust and the electric motor 20 stops, the electric motor 20 rotates in the reverse direction and moves the compression member 2 toward the standby position, so that the compression member 2 compresses the dust. There is no need to detect the position with a limit switch or the like and input a start signal to the electric motor 20 again, so that the number of electrical components can be reduced and the operation is simple.
In addition, since the electric motor 20 rotates in the reverse direction when the dust is compressed and the electric motor 20 is stopped, the position where the dust is compressed, that is, the compression end position is arbitrary.
Therefore, the compression member 2 can be moved with a small number of electric parts, the operation is simple, and the compression end position can be set arbitrarily.
[0033]
According to the second aspect of the present invention, the compression member 2 can be moved and the compression end position can be set arbitrarily by providing the detection unit, the connection switching unit, and the activation signal output unit.
In addition, the operation is simple because only the start signal is input from the start signal output means.
[0034]
According to the fourth aspect of the present invention, the dust in the first dust receiving portion 11 can be compressed by setting the second dust receiving portion 12 to the second position.
Moreover, since the first dust receiving portion 11 has a box shape with an open upper surface, general dust is put into the first dust receiving portion 11, and when the first dust receiving portion 11 becomes full, the first dust receiving portion 11 is compressed to reduce the volume and put the general dust again. Can be.
Therefore, the first dust receiving portion 11 can be used as a trash can for storing general trash, and the compression end position of the compression member 2 is arbitrary when compressing the general trash in the first dust receiving portion 11 many times. Good compression.
Further, by setting the second dust receiving portion 12 at the first position, dust on the second dust receiving portion 12, such as a can or a plastic bottle, can be compressed.
