Description

【０００１】
【発明の属する技術分野】
本発明は、微生物の力を利用して、生ごみの分解処理を行う生ごみ処理装置に関し、特に、家庭の台所で発生する調理屑のような生ごみの分解処理を行う生ごみ処理装置に関するものである。
【０００２】
【従来の技術】
従来から、微生物を利用して有機物及び水分を含有する汚泥を環境に影響を与えない程度に分解処理（発酵）することが行われており、このような処理を行う生ごみ処理装置が知られている。
【０００３】
この生ごみ処理装置は、例えば、生ごみ処理材を充填した生ごみ処理槽内に生ごみを投入して生ごみの分解処理運転を行うに当たり、生ごみの分解処理運転として分解処理能力が異なる複数段階の運転モードを有しており、生ごみの含水率を求め、生ごみの分解処理運転を含水率に対応した分解処理能力の運転モードで自動的に分解処理運転を行うようになっている。
【０００４】
そして、生ごみ処理材の含水率を求めるに当たっては、含水率判定用データ検出手段により生ごみ処理材に起因する含水率判定用データを求めて該データを予め設定した基準値と比較して生ごみ処理材の含水率を判定する含水率判定手段を設け、このようにして判定した生ごみ処理材の含水率に基づいて生ごみの分解処理運転を含水率に対応した分解処理能力の運転モードで自動的に分解処理運転を行うようになっていた。
【０００５】
上記含水率判定用データ検出手段はヒータと、ヒータによる加熱前とヒータによる一定時間加熱後の温度を検出するためのサーミスタとで構成してあり、この含水率判定用データ検出手段を生ごみ処理材に接するように設置し、含水率判定用データとしてヒータの加熱後と加熱前との温度差を求め、この温度差を予め設定した基準温度と比較して含水率を判定するようになっている。
【０００６】
しかしながら従来にあっては、上記含水率判定用データ検出手段の個体ばらつきとは無関係に検知を行って含水率の判定をおこない運転を制御していた。このため、含水率判定用データ検出手段の個体ばらつきが極度に大きく現れると含水率の判定が正確にできず、運転制御がうまく出来ず、生ごみ処理材が乾燥気味となったり、あるいは生ごみ処理材が水分過多となったりして生ごみの分解処理がうまく行えないことがあった。
【０００７】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、含水率判定用データ検出手段の個体ばらつきがあっても個体ばらつきを補正して含水率の判定が正確にできて、含水率に応じた適正なモードで分解処理運転ができる生ごみ処理装置を提供することを課題とするものである。
【０００８】
【課題を解決するための手段】
上記課題を解決するために本発明に係る生ごみ処理装置は、生ごみ処理材を充填した生ごみ処理槽１内に生ごみを投入して生ごみの分解処理運転を行うに当たり、生ごみの分解処理運転として分解処理能力が異なる複数段階の運転モードを有し、含水率判定用データ検出手段２により生ごみ処理材に起因する含水率判定用データを求めて該データを予め設定した基準値と比較して生ごみ処理材の含水率を判定する含水率判定手段３を設け、このようにして判定した生ごみ処理材の含水率に基づいて生ごみの分解処理運転を含水率に対応した分解処理能力の運転モードで自動的に分解処理運転を行う生ごみ処理装置において、生ごみ処理槽１に設けた生ごみを投入するための投入口７に開閉自在な蓋８を設け、蓋８の開閉がない状態で生ごみ処理能力が最も高い強運転モードが所定時間以上継続した場合に、上記含水率判定用データ検出手段２によって検出した生ごみ処理材に起因する含水率判定用データと比較する基準値を下げるように制御する補正手段４を設けて成ることを特徴とするものである。このような構成とすることで、生ごみ処理材の実際の含水率よりも低い方に判定されるように含水率判定用データが求められる傾向の個体ばらつきを有する含水率判定用データ検出手段２の場合は、必要以上に強運転モードが継続されるので、このような場合には補正手段４により基準値を下げて補正することで、含水率判定用データ検出手段２の個体ばらつきに対応でき、実際の含水率に応じた適正なモードで分解処理運転ができるものである。
【０００９】
また請求項２の生ごみ処理装置は、生ごみ処理材を充填した生ごみ処理槽１内に生ごみを投入して生ごみの分解処理運転を行うに当たり、生ごみの分解処理運転として分解処理能力が異なる複数段階の運転モードを有し、含水率判定用データ検出手段２により生ごみ処理材に起因する含水率判定用データを求めて該データを予め設定した基準値と比較して生ごみ処理材の含水率を判定する含水率判定手段３を設け、このようにして判定した生ごみ処理材の含水率に基づいて生ごみの分解処理運転を含水率に対応した分解処理能力の運転モードで自動的に分解処理運転を行う生ごみ処理装置において、生ごみの分解処理運転モードとして分解処理能力の高い順に強運転モード、標準運転モード、弱運転モードを設け、生ごみ処理槽１に設けた生ごみを投入するための投入口７に開閉自在な蓋８を設け、蓋８の開閉がない状態で弱運転モードが所定時間以上継続した場合に、上記含水率判定用データ検出手段２によって検出した生ごみ処理材に起因する含水率判定用データと比較する基準値を上げるように制御する補正手段４を設けて成ることを特徴とするものである。このような構成とすることで、生ごみ処理材の実際の含水率より高い方に判定されるように含水率判定用データが求められる傾向の個体ばらつきを有する含水率判定用データ検出手段２の場合は、必要以上に弱運転モードが継続されるので、このような場合には補正手段４により基準値を上げて補正することで、含水率判定用データ検出手段２の個体ばらつきに対応でき、実際の含水率に応じた適正なモードで分解処理運転ができるものである。
【００１０】
また、含水率判定用データ検出手段２をヒータ５と、ヒータ５による加熱前とヒータ５による一定時間加熱後の温度を検出するためのサーミスタ６とで構成し、該含水率判定用データ検出手段２を生ごみ処理材に接するように設置し、含水率判定用データとしてヒータ５の加熱後と加熱前との温度差を求め、この温度差を予め設定した基準温度と比較して含水率を判定する含水率判定手段３を設けることが好ましい。このような構成とすることで、含水率判定用データとしてヒータ５の加熱後と加熱前との温度差を求め、この温度差を予め設定した基準温度と比較して求め、このようにして求めた含水率判定用データと基準値と比較して、例えば基準値以上である場合は高含水率と判定し、基準値に満たない場合は低含水率であると判定するというようにして含水率を判定することができるものである。
【００１２】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１３】
図２には生ごみ処理装置９の概略斜視図が示してある。ケーシング１０内に木質細片のような生ごみ処理材を構成する担体を充填した生ごみ処理槽１が内装してあり、生ごみ処理槽１内にはモータ１１により回転する撹拌手段２１が設けてある。生ごみ処理槽１の上開口はケーシング１０の上面に設けた投入口７と連通しており、投入口７には開閉自在な蓋８が設けてある。また、生ごみ処理槽１の上部に空気供給口１３が設けてあり、更に、生ごみ処理槽１には排気手段１２が設けてあり、この排気手段１２は図２に示す実施形態においては、生ごみ処理槽１の上部に設けた排気ファンを備えた排気部１４と、排気部１４に接続した排気ダクト１５と、排気ダクト１５に設けた脱臭装置１６とで構成してある。また、本発明の生ごみ処理装置９には生ごみ処理槽１の内部の温度を昇温するための加熱手段１７が設けてあり、添付図面に示す実施形態においては、生ごみ処理槽１の外面部に面状ヒータを設けて加熱手段１７とした例が示してある。また、生ごみ処理槽１には生ごみ処理槽１内の生ごみ処理材の含水率を測定するための含水率判定用データ検出手段２が設けてある。
【００１４】
図１には本発明の生ごみ処理装置９の制御ブロック図が示してある。図中２０は装置全体の動作をコントロールするための制御手段であり、また、図中３は含水率判定用データ検出手段２で計測した生ごみ処理材に起因する含水率判定用データを求めて該データを予め設定した基準値と比較して生ごみ処理材の含水率を判定する含水率判定手段であり、また、図中４は含水率判定用データと比較するための基準値を補正するための補正手段４である。
【００１５】
含水率判定用データ検出手段２は図５に示すようにケース２３内にヒータ５とサーミスタ６とを入れて充填材２４を充填して構成してあり、この含水率判定用データ検出手段２を生ごみ処理槽１の内壁面に取付けて生ごみ処理材に接触するようにしてある。そして、ヒータ５による加熱前とヒータ５による一定時間加熱後の温度をサーミスタ６により検出し、ヒータ５の加熱後と加熱前との温度差を求めて含水率判定用データとし、含水率判定手段３により上記のようにして求めた含水率判定用データである上記温度差を予め設定した基準温度と比較することで含水率を判定するようにしている。図４にはヒータ５出力と、サーミスタ出力（温度）との関係を示しており、ヒータ５の加熱後と加熱前との温度差ΔＴを基準値である温度上昇したときのしきい値Ｔｔｈと比較し、ΔＴ＞Ｔｔｈの場合には高含水率（例えば含水率６５％以上）と判定し、ΔＴ≦Ｔｔｈの場合には低含水率（例えば含水率６５％未満）と判定するようになっている。なお、上記含水率判定用データ検出手段２により生ごみ処理材に起因する含水率判定用データを求めて該データを予め設定した基準値と比較して生ごみ処理材の含水率を判定するタイミングは撹拌手段２１による一定撹拌回数毎に行われるものである。
【００１６】
生ごみ処理装置９の分解処理運転モードは強運転モード、標準運転モード、弱運転モード、最弱運転モードの４段階の運転モードがあり、上記含水率判定用データ検出手段２で計測した含水率判定用データ（上記温度差）と基準値（上記基準温度）とを比較した含水率の判定情報に基づいて制御手段２０により、強運転モード、標準運転モード、弱運転モード、最弱運転モードのいずれかを自動的に選択して運転制御するようになっている。ここで、強運転モード、標準運転モード、弱運転モードは通常の生ごみ処理の運転モードであり、また、最弱運転モードは家を留守にしている場合などのように生ごみが投入されない場合における運転モードである。そして、通常の生ごみ処理の運転モードである強運転モード、標準運転モード、弱運転モードは、例えば表１に示すような制御がされるものである。
【００１７】
【表１】

【００１８】
蓋８を開いて投入口７から生ごみを投入すると、撹拌手段２１が駆動されて生ごみと生ごみ処理材とを撹拌混合して生ごみを生ごみ処理材内に分散させ、生ごみ処理材に生息した微生物の働きにより生ごみを分解処理（発酵処理）するものである。
【００１９】
ここで、本発明においては、図３に示すように、蓋８の開直前の分解処理運転モードが弱運転モード又は標準運転モードの場合には蓋８の開後に標準運転モードに移行し、また、蓋８の開直前の分解処理運転モードが強運転モードの場合には蓋８の開後に強運転モードに移行するように制御手段２０により制御し、その後、上記のように標準運転モードまたは強運転モードによる運転中に含水率判定用データ検出手段２により生ごみ処理材に起因する含水率判定用データを検出し、含水率判定手段３により上記含水率判定用データを予め設定した基準値と比較して生ごみ処理材の含水率を判定し、この判定情報に基づいて制御手段２０によりその含水率に応じた分解処理運転モードに移行させるように制御するものである。
【００２０】
つまり、蓋８を開くと標準運転モード又は強運転モードで運転される（図３のように強運転モード時に蓋８を開くと強運転モードで運転され、標準運転モード時や弱運転モード時や最弱運転モード時に蓋８を開くと標準運転モードで運転される）のであるが、蓋８を開いて標準運転モード又は強運転モードで運転されると、撹拌手段２１による一定撹拌回数毎に含水率判定用データ検出手段２によりヒータ５の加熱後と加熱前との温度差を求め、この温度差が基準値を越えると所定含水率（実施例では含水率６５％）以上であると判定し、このように含水率が６５％以上と判定したら標準運転モードに移行し、更に、標準運転モードに移行した後、含水率６５％以上と判定する回数が過去１６回中１１回以上あれば強運転モードに移行するように制御し、また、強運転モードに移行したのち含水率６５％以上の判定回数が過去１６回中１１回未満の場合には標準運転モードに移行し、更に、標準運転モードに移行したのち含水率６５％以上の判定回数が過去１６回中３回未満で且つ最後の含水率６５％以上の判定から一定時間（例えば４時間５０分）経過した場合には弱運転モードに移行し、更に、弱運転モードに移行したのちに一定時間（例えば７２時間）以上蓋８が閉のままの場合には最弱運転モードに移行するというような制御が制御手段２０により行われるものである。なお、上記含水率の判定は撹拌手段２１による一定撹拌回数毎に含水率判定用データ検出手段２により含水率判定用データを検知して含水率判定手段３により判定する回数をカウントし、１６回カウントすると、リセットし１７回目になると新たな１回目としてこれから再びカウントを再開し１６回カウントすると、リセットするということを繰り返しながら上記制御を行うものである。
【００２１】
ここで含水率判定用データ検出手段２には例えば含水率判定用データ検出手段２で検出する温度上昇度の個体ばらつきがあり、この個体ばらつきにより同じ含水率でも強運転モードに行きやすかったり、あるいは弱運転モードに行きやすかったりするという傾向がでる。ここで、含水率判定用データ検出手段２として温度上昇値が低い方にばらつく含水率判定用データ検出手段２を使用した場合には強運転モード時間が長く続く傾向がある。逆に含水率判定用データ検出手段２として温度上昇値が高い方にばらつく含水率判定用データ検出手段２を使用した場合には弱運転モード時間が長く続く傾向がある。
【００２２】
このため、本発明においては、蓋８の開閉がない状態で生ごみ処理能力が最も高い強運転モードが所定時間以上継続した場合に基準値を下げるように補正手段４により補正を行うものであり、例えば、基準値を０．５°下げるように補正する。一方、蓋８の開閉がない状態で弱運転モードが所定時間以上継続した場合に基準値を上げるように補正手段４により補正を行うものであり、例えば、基準値を０．５℃下げるように補正する。このように基準値を補正することで、含水率判定用データ検出手段２の温度上昇値の個体間ばらつきがあってもそれを補正して実際の含水率に応じた適正なモードで分解処理運転ができ、含水率判定用データ検出手段２の個体ばらつきに起因する水分過多や過乾燥を防ぐことができるものである。
【００２３】
ところで、上記のような生ごみ処理装置においては撹拌手段２１による一定撹拌回数毎に含水率判定用データ検出手段２によりヒータ５の加熱後と加熱前との温度差を求めるのであるが、撹拌手段２１で撹拌する際には排気ファンを運転するようになっている。上記ヒータ５と、排気ファンとはデューティ制御によりコントロールしているが、上記ヒータ５の出力と排気ファンの出力の位相（オン、オフのタイミング）が図７のように同じ場合には負荷２つ分の瞬間最大消費電力に対応する電源が必要であり、装置の大型化、コスト高になるという問題があるので、図６のようにデューティ制御によりコントロールするヒータ５の出力と排気ファンの出力の位相（オン、オフのタイミング）をずらす（例えばヒータ５の出力のオン、オフのタイミングを、排気ファンの出力のオン、オフのタイミングに対して５０％遅延させる）ことで瞬間最大消費電力を低減することができて、装置の小型化、コストダウンを図ることができるものである。
【００２４】

[0003]
For example, when this garbage disposal apparatus performs the decomposition treatment operation of garbage by putting the garbage into the garbage treatment tank filled with the garbage treatment material, the decomposition treatment capacity differs as the garbage decomposition operation. It has a multi-stage operation mode, the moisture content of the garbage is obtained, and the decomposition treatment operation of the garbage is automatically performed in the operation mode of the decomposition treatment capacity corresponding to the moisture content.

Yes.
[0006]
Conventionally, however, the operation is controlled by performing detection regardless of the individual variation of the moisture content determination data detecting means to determine the moisture content. For this reason, if the individual variation of the moisture content determination data detection means appears extremely large, the moisture content cannot be determined accurately, the operation control cannot be performed properly, the garbage treatment material becomes dry, or the garbage In some cases, the treatment material would be excessively watery and the garbage could not be decomposed successfully.

The operation mode has a plurality of stages with different capacities, the moisture content determination data detection means 2 obtains moisture content determination data caused by the garbage treatment material, and compares the data with a preset reference value to produce garbage. The moisture content determination means 3 for determining the moisture content of the treatment material is provided, and the operation mode of the decomposition treatment capacity corresponding to the moisture content is determined based on the moisture content of the garbage treatment material thus determined. In the garbage processing device that automatically performs the decomposition treatment operation in the garbage disposal processing mode, the garbage disposal tank 1 is provided with a strong operation mode, a standard operation mode, and a weak operation mode in descending order of the decomposition treatment capability. Raw When the weak operation mode continues for a predetermined time or more without opening / closing the lid 8, the moisture content determination data detecting means 2 detects the opening 8 for opening the lid.

By adopting such a configuration, the moisture content determination data detection means 2 having the individual variation in the tendency for the moisture content determination data to be determined to be determined to be higher than the actual moisture content of the garbage treatment material. In this case, since the weak operation mode is continued more than necessary, in such a case, the correction means 4 can be corrected by raising the reference value to cope with the individual variation of the moisture content determination data detection means 2, The decomposition treatment operation can be performed in an appropriate mode according to the actual moisture content.
[0010]
Further, the moisture content determination data detection means 2 comprises a heater 5 and a thermistor 6 for detecting the temperature before heating by the heater 5 and after heating for a certain period of time by the heater 5, and the moisture content determination data detection means. 2 is placed in contact with the garbage treatment material, the temperature difference between after heating of the heater 5 and before heating is obtained as moisture content determination data, and the moisture content is compared with a preset reference temperature.

It is attached to the inner wall surface of the garbage processing tank 1 so as to come into contact with the garbage processing material. Then, the temperature before heating by the heater 5 and after heating for a certain time by the heater 5 is detected by the thermistor 6, the temperature difference between after heating by the heater 5 and before heating is obtained and used as moisture content determination data, and moisture content determination means 3, the moisture content is determined by comparing the temperature difference, which is the moisture content determination data obtained as described above, with a preset reference temperature. FIG. 4 shows the relationship between the heater 5 output and the thermistor output (temperature). The threshold value Tth when the temperature difference ΔT between after heating the heater 5 and before heating is increased as a reference value. In comparison, when ΔT> Tth, the water content is determined to be high (for example, a water content of 65% or more), and when ΔT ≦ Tth, the water content is determined to be low (for example, the water content is less than 65%). Yes. Timing for determining the moisture content of the garbage treatment material by obtaining the moisture content judgment data caused by the garbage treatment material by the moisture content judgment data detection means 2 and comparing the data with a preset reference value. Is performed at every fixed number of times of stirring by the stirring means 21.

The decomposition treatment operation mode of the garbage disposal device 9 has four operation modes: a strong operation mode, a standard operation mode, a weak operation mode, and a weakest operation mode, and the moisture content measured by the moisture content determination data detection means 2 described above. Based on the moisture content determination information obtained by comparing the determination data (the above temperature difference) and the reference value (the above reference temperature), the control means 20 performs the strong operation mode, the standard operation mode, the weak operation mode, and the weakest operation mode. One of them is automatically selected for operation control. Here, the strong operation mode, standard operation mode, and weak operation mode are normal garbage disposal operation modes, and the weakest operation mode is when no garbage is thrown in, such as when the house is away. It is the operation mode in. And the control as shown in Table 1 is performed, for example, in the strong operation mode, the standard operation mode, and the weak operation mode, which are normal garbage disposal operation modes.

[Table 1]

[0018]
When the lid 8 is opened and the garbage is introduced from the inlet 7, the agitation means 21 is driven to agitate and mix the garbage and the garbage treatment material to disperse the garbage in the garbage treatment material. Garbage is decomposed (fermented) by the action of microorganisms that inhabit the wood.
[0019]
Here, in the present invention, as shown in FIG. 3, when the disassembly treatment operation mode immediately before the lid 8 is opened is the weak operation mode or the standard operation mode, the operation mode is shifted to the standard operation mode after the lid 8 is opened. When the disassembly treatment operation mode immediately before opening the lid 8 is the strong operation mode, the control means 20 controls so as to shift to the strong operation mode after the lid 8 is opened, and then the standard operation mode or the strong operation mode as described above. During operation in the operation mode, the moisture content determination data detection means 2 detects moisture content determination data caused by the garbage treatment material, and the moisture content determination means 3 sets the moisture content determination data in advance as a reference value and In comparison, the moisture content of the garbage treatment material is determined, and based on this determination information, the control means 20 performs control so as to shift to the decomposition treatment operation mode corresponding to the moisture content.
[0020]
That is, when the lid 8 is opened, it is operated in the standard operation mode or the strong operation mode (as shown in FIG. 3, when the lid 8 is opened in the strong operation mode, the operation is performed in the strong operation mode, and in the standard operation mode or the weak operation mode. When the lid 8 is opened in the weakest operation mode, the operation is performed in the standard operation mode. However, when the lid 8 is opened and the operation is performed in the standard operation mode or the strong operation mode, the water content is included at every fixed number of times of stirring by the stirring means 21. The rate difference data detection means 2 obtains the temperature difference between after heating the heater 5 and before heating, and if this temperature difference exceeds the reference value, it is determined that the moisture content is equal to or higher than a predetermined moisture content (65% moisture content in the embodiment). If the moisture content is determined to be 65% or more in this way, the mode shifts to the standard operation mode. Further, after the transition to the standard operation mode, if the number of determinations that the moisture content is 65% or more is 11 times or more in the past 16 times, it is strong. Move to operation mode If the number of determinations with a moisture content of 65% or more is less than 11 out of the past 16 after shifting to the strong operation mode, the mode is shifted to the standard operation mode, and further, the water content is transferred to the standard operation mode. When the number of determinations with a rate of 65% or more is less than 3 out of the past 16 times and when a predetermined time (for example, 4 hours and 50 minutes) has passed since the last determination with a moisture content of 65% or more, the mode shifts to a weak operation mode. When the lid 8 remains closed for a certain time (for example, 72 hours) after shifting to the weak operation mode, the control means 20 performs control such as shifting to the weakest operation mode. In addition, the determination of the moisture content is performed by counting the number of times the moisture content determination data is detected by the moisture content determination data detection unit 2 and determined by the moisture content determination unit 3 every time the number of times of stirring by the stirring unit 21 is 16 When counting is performed, the above-described control is performed while repeating the resetting when the count is reset and the count reaches the 17th time, and the count is restarted again after the count is counted for the 16th time.
[0021]
Here, the moisture content determination data detection means 2 has, for example, individual variations in the temperature rise detected by the moisture content determination data detection means 2, and this individual variation makes it easy to reach the strong operation mode even at the same moisture content, or There is a tendency to easily go to weak driving mode. Here, when the moisture content determination data detection means 2 that varies as the moisture content determination data detection means 2 has a lower temperature increase value, the strong operation mode time tends to last longer. On the contrary, when the moisture content determination data detection means 2 that varies in the higher temperature rise value is used as the moisture content determination data detection means 2, the weak operation mode time tends to last longer.
[0022]
For this reason, in the present invention, the correction means 4 performs correction so as to lower the reference value when the strong operation mode with the highest garbage disposal capacity continues for a predetermined time or longer without the lid 8 being opened or closed. For example, the reference value is corrected to be lowered by 0.5 °. On the other hand, the weak operation mode with no opening and closing of the lid 8 is intended to perform the correction by the correction means 4 so as to raise the reference value when the predetermined time or longer, for example, a reference value to decrease 0.5 ℃ to correct. By correcting the reference value in this way, even if there is an inter- individual variation in the temperature rise value of the moisture content determination data detection means 2, it is corrected and the decomposition treatment operation is performed in an appropriate mode according to the actual moisture content. It is possible to prevent excessive moisture and overdrying due to individual variation of the moisture content determination data detection means 2.
[0023]
By the way, in the garbage processing apparatus as described above, the temperature difference between after heating of the heater 5 and before heating is obtained by the moisture content determination data detection means 2 at every fixed number of times of stirring by the stirring means 21. When stirring at 21, the exhaust fan is operated. The heater 5 and the exhaust fan are controlled by duty control. When the phase of the output of the heater 5 and the output of the exhaust fan (on / off timing) is the same as shown in FIG. Therefore, there is a problem that the power supply corresponding to the instantaneous maximum power consumption of minutes is required, and the size and cost of the apparatus are increased. Therefore, the output of the heater 5 and the output of the exhaust fan controlled by duty control as shown in FIG. Reduce the instantaneous maximum power consumption by shifting the phase (ON / OFF timing) (for example, delaying the ON / OFF timing of the heater 5 output by 50% with respect to the ON / OFF timing of the exhaust fan output). Therefore, it is possible to reduce the size and cost of the apparatus.
