- step S2 measurement of the operation time t is started, and the process proceeds to step S3.
- step S3 the dehumidifying operation is continued for a predetermined set time (core time).
- the core time is set to 70 minutes.
- the core time is a time for drying clothes to some extent before reaching the next step.

- step S11 it is determined whether or not the operation is stopped before the dehumidifying operation time Y elapses when the user operates the operation switch. Under normal circumstances, the clothes drying operation is terminated in step S13 through step S12 for determining whether or not the remaining dehumidifying operation time Y calculated in step S9 has been reached.

Note that the initial value of the determination count is 0. In step S21, 1 point of the determination count is subtracted, the result is stored in the storage unit 7d, and the process proceeds to step S22.
- step S22 it is determined whether or not the cumulative count number of the determination count is equal to or less than a predetermined numerical value (“ ⁇ 2” in the present embodiment).

- the cumulative count may be set to a value smaller than “ ⁇ 2”.
- the determination count is subtracted by one point.
- the size of the subtracted point may be changed depending on the timing of the stop time. For example, when stopping more quickly, the point to be subtracted may be increased, and the point to be subtracted may be decreased as the dehumidifying time Y is closer.
- step S11 if the user does not stop the operation before the remaining dehumidifying time Y elapses, it is determined in step S12 whether or not the time Y calculated in step S9 is reached. To do.
- step S12 when the operation end condition is met (when the time Y has elapsed), the process proceeds to step S13, and the clothes drying operation is once ended. Thereafter, in step S14, the state is internally shifted to a standby state.
- the standby state is a state where dehumidification and air blowing are stopped.
- step S12 when the operation end condition is not met (when time Y has not elapsed), the process proceeds to step S11.
- a time limit is provided, and it is determined whether or not a predetermined time has elapsed in step S16.
- a predetermined time elapses in the standby state
- the process proceeds to step S17 to end the operation.
- This time limit is 5 hours in the present embodiment.
- the dehumidifier is in the standby state
- the operation is started again, it can be assumed that the user has confirmed the degree of drying of the laundry and has determined that the drying operation is necessary again, and when the operation is resumed before proceeding to Step S17, Step S31 is performed.
- step S31 the determination count is accumulated by one point, and the process proceeds to step S32.
- This result is stored in the storage unit 7d.
- step S32 it is determined whether or not the cumulative count number of the determination count is greater than or equal to a predetermined numerical value (“+2” in the present embodiment). That is, in the present embodiment, it is determined whether or not the user has restarted the operation twice after the remaining dehumidifying time Y has elapsed in the current and past clothes drying operations. In other words, in addition to whether or not the user intends to dry the clothes again even though he / she drove until the dehumidification time Y, erroneous determination due to erroneous input or mischief other than the user is prevented. ing.
- step S33 the application rank Dx is increased by one, and the rank to be applied at the next operation is determined.
- the determination count is reset, and the process proceeds to step S34 to perform additional clothes drying operation.
- the operation time is corrected in a direction in which the operation time is extended.
- the above control flow is summarized as follows. (1) When the user turns off the operation before the remaining dehumidifying operation time Y elapses. It is estimated that the user has determined that dehumidification is sufficient at an earlier stage than the remaining dehumidifying operation time Y that has been set. After the next operation, the remaining dehumidifying operation time Y is made shorter than this time (changed by lowering the application rank Dx). (2) When dehumidification is performed until the remaining dehumidifying operation time Y (when no additional operation is performed). It is estimated that the user has determined that the dehumidification is sufficient for the remaining dehumidifying operation time Y that has been set.
- the dehumidifying operation time Y is obtained by the coefficient obtained by determining the dehumidifying operation time Y set this time (no change in the application rank Dx).
- the timing at which the user stops driving that is, the timing at which the user operates the operation switch 8 is estimated to estimate the user's degree of dryness of the clothing.
- a dryness evaluation switch 11 as shown in FIG. 4 is provided to actively support the user. Evaluation information may also be input.

- the degree of drying of the laundry that is the object to be dried is corrected for the operation time determined by the control circuit 7 by evaluating the degree of drying of the user's clothing,
- the operation is controlled with the corrected operation time.
- the user's evaluation information input from the evaluation information input means may be stored in the storage unit 7d, and the correction amount of the driving time may be changed by the user performing repeated evaluation. Thereby, the user's satisfaction with drying is reflected as evaluation information in the operation time of the clothes drying operation, and it becomes possible to perform the drying operation of the laundry suitable for each taste.

Abstract
Description
以下、図面を参照して、本発明の実施の形態1を説明する。
図1は、本実施の形態に係る除湿機を示す外観斜視図を示す。図2は、本実施の形態に係る除湿機の内部構造の概略構成図を示す。図3は、風向可変手段の概略斜視図を示す。図4は、本実施の形態に係る除湿機の制御ブロック図を示す。図5は、本実施の形態に係る除湿機の衣類乾燥運転のときの動作を示すフローチャートを示す。
この筐体100には、内部に室内空気Aを取り込むための吸込口101と、水分が除去された乾燥空気Bを筐体100から室内へ排出する排気口103が開口している。また、筐体100の内部には、吸込口101に取り込まれた空気から除去された水分を溜める貯水タンク102が設けられる。
排気口103には、乾燥空気Bの風向を可変可能な風向可変手段1が設けられている。この風向可変手段1は、鉛直方向の風向を可変する縦方向ルーバー1aと、水平方向の風向を可変する横方向ルーバー1bによって構成されている。
貯水タンク102は、筐体100の内部から着脱可能に取り付けられている。
除湿手段5によって室内空気Aから除去された水分は、凝縮水Cとして貯水タンク102に貯留され、水分が取り除かれた空気は乾燥空気Bとなる。
これにより、縦方向(上下方向)に風向を可変可能に構成されている。
これにより、横方向(左右方向)に風向を可変可能に構成されている。
これにより、赤外線センサー6による表面温度の検出範囲は、風向可変手段1によって可変される乾燥空気Bの方向とほぼ同一となる。つまり、赤外線センサー6は、風向可変手段1が送風可能な範囲内の全領域の表面温度を検出することができる。
この赤外線センサー6は、熱放射を吸収することによって昇温する赤外線吸収膜6aの感熱部分の温度(温接点)と、サーミスタ6bによって検出される赤外線吸収膜6aの温度(冷接点)との差を電圧等の電気信号に変換し、後述する制御回路7に入力する。この電気信号の大きさから所定領域の表面温度を判別できる。
これにより、室内空気Aは、吸込口101から除湿機筐体100内に取り込まれ、温度センサー3及び湿度センサー4によりそれぞれ室内の温度と湿度が検出された後、除湿手段5により除湿されて乾燥空気Bとなり、排気口103から室内に吹き出される。
制御回路7は、各種センサーや各種スイッチからの入力と所定のアルゴリズムにより、除湿機J全体の運転を制御するものであり、入力回路7a、出力回路7b、CPU7c、記憶部7d、運転開始からの運転時間を計測する運転時間計測手段であるタイマー部7eを有する。
尚、乾燥度評価スイッチ11は、後述する動作の説明(ステップS11以降)で示すように、代わりに運転スイッチ8を用いてもよい。例えば、使用者が運転スイッチ8を操作するタイミングから、乾燥度の評価を推測するものでも良い。
更に、この制御回路7には、出力回路7bを介して、除湿機の状態を報知する表示部12、除湿装置5、ファンモーター2a、縦方向可変モーター1c、横方向可変モーター1dなどの電気部品が接続されている。
尚、以下の説明において、時間測定、湿度測定、温度測定は、それぞれ上述したタイマー部7e、湿度センサー10、温度センサー9により行われており、各種演算処理は、制御回路7により実行されるものである。
ステップS3では、所定の設定された時間(コアタイム)の間、除湿運転を継続し、コアタイムに達すると、ステップS4に移行する。尚、本実施の形態では、コアタイムは70分に設定されている。ここで、コアタイムとは、次のステップに至る前に、ある程度衣類を乾燥させるための時間である。
ステップS6では、雰囲気相対湿度(室内空気の湿度)が50%を切ったときの運転開始からの運転時間t1と、温度センサー9が検知する雰囲気温度(室内空気の温度)である検出温度Tを得て、ステップS7に移行する。そして、ステップS7では、検出温度Tと運転時間t1の積を計算して、ステップS8に移行する。
この係数Dとは、衣類乾燥運転の乾燥運転時間を変化させる変数の1つであり、実験により求められた次式により算出される。
『D=a×(T×t1)^b』(「^」は累乗を表す。)
この適用ランクDxは、目標とする乾燥度に応じてD1~D5が設定されており、それぞれに対応する係数aと係数bを有し、前回までの運転で、後述するステップS11以降の処理により求められて適用されている。
尚、本実施の形態では、適用ランクDxは5段階に設定されているが、より細かく衣類乾燥運転の運転時間を変化させる必要があれば5段階以上に設定してもよく、また、細かく運転時間を変化させる必要がなければ5段階より少ない設定にして良い。
また、適用ランクDxのランクごとの係数aおよびbは、制御回路7内の記憶部7dに記憶されており、後述の使用者による評価情報によりランクが上下した際に、適用となるランクでの係数aおよびbが読み込まれ計算に使用される。
『Y=t1×(D-T/100)』
により算出し、残りの除湿運転時間Yを決定して、ステップS10に移行する。
ステップS10で運転時間がZに到達すると、ステップS11に移行する。
例えば、ステップS10が構成されていることにより、衣類乾燥運転が開始されて間もなく、誤操作により運転を停止してしまった場合、衣類がほとんど乾いていない状態での乾燥度合いに対する評価を除外することができ、誤判定の防止や判定の精度向上をすることができる。
尚、本実施の形態では、使用者が運転を停止したタイミング、つまり、使用者が運転スイッチ8を操作したタイミングを見て、使用者の衣類の乾燥度合いに対する評価を推測している。
本来であれば、ステップS9にて算出されたのこりの除湿運転時間Yに到達したか否かを判定するステップS12を経て、ステップS13にて衣類乾燥運転終了となる。
しかし使用者が、除湿運転時間Yが経過する前に、洗濯物の乾燥度合いを確認し、以降の乾燥運転は不要と判断して、ステップS12に移行する前に運転を停止した場合には、ステップS21に移行する。
ステップS21では、判定カウントの1ポイント減算を行い、その結果を記憶部7dに記憶して、ステップS22に移行する。
本実施の形態では、今回と過去の衣類乾燥運転において、使用者が残りの除湿時間Yが経過する前に、2度の運転停止を行ったかどうかを判定している。つまり、使用者が、除湿時間Yまでの運転を不要とする意思があるかどうかに加えて、誤入力や使用者以外のいたずらなどによる誤判定を防止している。
以上のように、使用者が残りの除湿運転時間Yが経過する前に運転停止を行うことにより、以降の運転時において、除湿運転時間Yは短縮される方向に補正されていく。
また、残りの除湿時間Yより前に停止した場合、判定カウントを1ポイント減算するとしたが、停止した時間のタイミングにより減算するポイントの大きさを変えても良い。例えば、より早く停止した場合、減算するポイントを大きくし、除湿時間Yに近いほど減算するポイントを小さくすると良い。
ステップS12において、運転終了条件に合致している場合(時間Yを経過した場合)、ステップS13に移行して一旦衣類乾燥運転は終了となる。その後、ステップS14において、内部的に待機状態へと移行する。尚、待機状態とは、除湿及び送風を停止した状態である。
ステップS12において、運転終了条件に合致していない場合(時間Yを経過していない場合)、ステップS11に移行する。
ここで、除湿機が待機状態であるときに、使用者が再度運転スイッチ8を押して衣類乾燥運転を開始したかどうかをステップS15において判定する。再度運転を開始したということは、使用者が洗濯物の乾燥度合いを確認し、再度乾燥運転が必要と判断したと推測でき、ステップS17に移行する前に運転を再開した場合には、ステップS31に移行する。
そして、ステップS32では、判定カウントの累積カウント数が所定数値(本実施の形態では「+2」)以上であるかどうかを判定している。
つまり、本実施の形態では、今回と過去の衣類乾燥運転において、使用者が残りの除湿時間Yが経過した後に、2度の運転再開を行ったか否かを判定している。つまり、使用者が、除湿時間Yまでの運転したのにもかかわらず、再度衣類を乾燥したいと意思があるか否かに加えて、誤入力や使用者以外のいたずらなどによる誤判定を防止している。
以上のように、使用者が待機状態中に運転再開を行うことにより、運転時間は延長される方向に補正されていく。
(1)使用者が残りの除湿運転時間Yが経過する前に運転をOFFした場合。
使用者が、設定した残りの除湿運転時間Yより早い段階で、除湿が十分と判断したと推測。次回の運転以降、今回より残りの除湿運転時間Yが短くなるようにする(適用ランクDxを下げて変化)。
(2)残りの除湿運転時間Yまで除湿を行った場合(追加運転は行わない場合)。
使用者が、設定した残りの除湿運転時間Yで除湿が十分と判断したと推測。つまり、設定通りの残りの除湿時間で問題なかったと判断。次回の運転以降も、今回設定した除湿運転時間Yを求めた係数で除湿運転時間Yを求める(適用ランクDxの変化無し)。
(3)残りの除湿運転時間Yまで除湿を行った後、使用者が追加して運転を行った場合。
使用者が、除湿が不十分と判断したと推測。次回の運転以降、今回より残りの除湿運転時間Yが長くなるようにする(適用ランクDxを上げて変化)。
尚、乾燥度評価スイッチ11で乾燥度の評価を使用者が入力する場合、上記の(1)~(3)は、それぞれ評価「乾燥しすぎ」は(1)に相当し、評価「ちょうど良い」は(2)に相当し、評価「乾燥不足」は(3)に相当する。
また、評価情報入力手段から入力された使用者の評価情報を記憶部7dに記憶し、使用者が評価を重ねることにより、運転時間の補正量を変化させてもよい。これにより使用者の乾燥に対する満足度を評価情報として衣類乾燥運転の運転時間に反映し、個々の嗜好に適した洗濯物の乾燥運転を行うことが可能となる。
