The exhaust port 103 is provided with a wind direction varying means 1 capable of varying the wind direction of the dry air Q. The wind direction varying means 1 is composed of a vertical louver 1a that varies the wind direction in the vertical direction and a horizontal louver 1b that varies the wind direction in the horizontal direction. Further, the wind direction varying means 1 is provided with an infrared sensor 6.
The water storage tank 102 is detachably attached from the inside of the housing 100.
 更に、図2を参照すると、除湿機Jの内部には、吸込口101から室内空気Pを吸込み、排気口103から乾燥空気Qを排出する気流を発生させる送風ファン2と、この送風ファン2を回転させるファンモーター2aと、吸込口101から吸引された室内空気Pの温度を検出する温度センサー3(温度検出手段)と、室内空気Pの湿度を検出する湿度センサー4(湿度検出手段)と、室内空気Pに含まれる水分を除去して乾燥空気Qを生成する除湿手段5と、縦方向ルーバー1aを鉛直方向に可変する縦方向可変モーター1cと、横方向ルーバー1bを水平方向に可変する横方向可変モーター1dと、表面温度検出手段である赤外線センサー6と、各部を制御する制御手段である制御回路7が備えられている。 Further, referring to FIG. 2, the inside of the dehumidifier J includes a blower fan 2 that sucks room air P from the suction port 101 and generates an airflow that discharges dry air Q from the exhaust port 103, and the blower fan 2. A rotating fan motor 2a, a temperature sensor 3 (temperature detecting means) for detecting the temperature of the indoor air P sucked from the suction port 101, a humidity sensor 4 (humidity detecting means) for detecting the humidity of the indoor air P, Dehumidifying means 5 that removes moisture contained in the indoor air P to generate dry air Q, a longitudinal variable motor 1c that varies the longitudinal louver 1a in the vertical direction, and a lateral that varies the lateral louver 1b in the horizontal direction.

Examples of methods used for the dehumidifying means 5 include a method in which a heat pump circuit is configured to condense moisture in the air in an evaporator, and a desiccant method in which moisture in the air removed by the adsorbent is condensed in a heat exchanger. It is used.
The water removed from the room air P by the dehumidifying means 5 is stored in the water storage tank 102 as condensed water C, and the air from which the water has been removed becomes dry air Q.
 次に、図3を参照すると、風向可変手段1を構成する縦方向ルーバー1aは、筐体100の幅方向に延びる長方形状の開口を有し、前述した縦方向可変モーター1cの回転軸をほぼ軸として鉛直方向に可変可能に構成されている。

Further, the horizontal louvers 1b are arranged at equal intervals in the vertical louver 1a, and are pivotally supported by a collar opposite to the opening of the vertical louver 1a so as to be variable in the horizontal direction. It is configured to be linked to the drive.
Thereby, it is comprised so that a wind direction can be varied in a horizontal direction (left-right direction).
 赤外線センサー6は、縦方向ルーバー1a内に配置されたほぼ中央の横方向ルーバー1bの片面に取り付けられている。
 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Q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。
The infrared sensor 6 is attached to one surface of a substantially central lateral louver 1b disposed in the longitudinal louver 1a.
Thereby, the detection range of the surface temperature by the infrared sensor 6 becomes substantially the same as the direction of the dry air Q which is varied by the wind direction varying means 1. That is, the infrared sensor 6 can detect the surface temperature of the entire region within the range in which the wind direction varying means 1 can blow.
 この赤外線センサー6は、例えば、熱起電力効果を利用したものが用いられており、所定領域の表面から発せられる熱放射(赤外線)を受ける赤外線吸収膜6aと、赤外線吸収膜6aの温度を検出するサーミスタ6bとで構成されている(図3参照)。
 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。
The infrared sensor 6 is, for example, one that uses a thermoelectromotive force effect, and detects the temperature of the infrared absorption film 6a that receives thermal radiation (infrared rays) emitted from the surface of a predetermined region, and the temperature of the infrared absorption film 6a. And the thermistor 6b (see FIG. 3).
The infrared sensor 6 has a difference between the temperature of the heat-sensitive part of the infrared absorption film 6a that rises in temperature by absorbing thermal radiation (hot contact) and the temperature of the infrared absorption film 6a detected by the thermistor 6b (cold contact). Is converted into an electric signal such as a voltage and input to a control circuit 7 to be described later. The surface temperature of the predetermined region can be determined from the magnitude of this electrical signal.
 本実施の形態では、赤外線センサー6は、検出する物体の表面温度の差から、洗濯物などの被乾燥物Rを見分ける為に用いる。
 図5及び図6を参照すると、制御回路7は、赤外線センサー6の検知可能領域Aを所定の大きさのます目に区切り、ます目ごとの表面温度を判断することで、被乾燥物Rの位置や乾燥の度合などを判断する。
 例えば、検知可能領域A内で塗潰されている部分Bが、他の部分より低い温度である状態が検知されている。尚、図中で濃く塗潰されている部分ほど、より低温となっている。
 そして、制御回路7は、表面温度が低い部分に洗濯物が位置すると判断し、除湿運転の際に、当該位置に効率よく除湿空気が当るように、風向可変手段1の向きやファンモーターの動きを制御する。
In the present embodiment, the infrared sensor 6 is used to distinguish a material to be dried R such as laundry from the difference in the surface temperature of the object to be detected.
Referring to FIG. 5 and FIG. 6, the control circuit 7 divides the detectable area A of the infrared sensor 6 into squares of a predetermined size, and determines the surface temperature of each eye to determine the surface of the material R to be dried. Judge position and dryness.
For example, a state in which the portion B painted in the detectable region A is at a lower temperature than the other portions is detected. In the figure, the darker the part, the lower the temperature.
Then, the control circuit 7 determines that the laundry is located in a portion where the surface temperature is low, and the direction of the wind direction varying means 1 and the movement of the fan motor are arranged so that the dehumidified air efficiently hits the position during the dehumidifying operation. To control.
 制御回路7は、操作部(図示せず)のスイッチ操作から除湿モードが選択されたことを検知した場合には、室内の湿度が最適湿度となるように、風向可変手段1を駆動して排気口103から送風可能にし、ファンモーター2aを駆動して送風ファン2を回転させ、除湿手段5を駆動する。 When the control circuit 7 detects that the dehumidifying mode is selected from the switch operation of the operation unit (not shown), the control circuit 7 drives the wind direction varying means 1 so that the indoor humidity becomes the optimum humidity, and exhausts the air. The fan 103 can be blown, the fan motor 2a is driven to rotate the blower fan 2, and the dehumidifying means 5 is driven.
 また、制御回路7は、室内の所望領域の方向に送風されるように、風向可変手段1の縦方向可変モーター1cと横方向可変モーター1dを駆動する。
 これにより、室内空気P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Qとなり、排気口103から室内に吹き出される。
Further, the control circuit 7 drives the longitudinal direction variable motor 1c and the lateral direction variable motor 1d of the wind direction varying means 1 so that the air is blown in the direction of the desired area in the room.
As a result, the indoor air P is taken into the dehumidifier housing 100 from the suction port 101, and the indoor temperature and humidity are detected by the temperature sensor 3 and the humidity sensor 4, respectively, and then dehumidified by the dehumidifying means 5 and dried. Air Q is discharged from the exhaust port 103 into the room.

 そして、この係数aと係数bは、適用ランクDx毎にそれぞれ設定された係数であり、後述するステップS14とステップS15において、除湿時間Yを算出する為に用いるものである。
Here, referring to FIG. 8, the application rank Dx is set to D1 to D5 according to the target dryness, and has a coefficient a and a coefficient b corresponding to each of them, and the operation up to the previous time. The processing after step S17, which will be described later, is obtained and applied for each condition such as the amount of the material R to be dried and the degree of ease of drying the material R to be dried.
The coefficients a and b are coefficients set for each application rank Dx, and are used to calculate the dehumidifying time Y in steps S14 and S15 described later.
 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。
 そして、図9(b)を参照すると、適用ランクDxテーブルとは、赤外線センサー6が検知した被乾燥物Rが占めるエリアの大きさ「大」「中」「小」と、被乾燥物Rの乾燥の容易度「ノーマル」「乾燥容易」で、6つの対象となる値が設定されている。
In the present embodiment, the application rank Dx is set in five stages, but if it is necessary to change the operation time of the clothes drying operation more finely, it may be set in five stages or more, and the operation time is finely set. If it is not necessary to change, the setting may be set to less than 5 levels.
Then, referring to FIG. 9B, the application rank Dx table is the size “large”, “medium”, “small” of the area occupied by the dried object R detected by the infrared sensor 6 and the dried object R. Six target values are set with the ease of drying “normal” and “easy to dry”.
 尚、初めて運転する状態では、初期値D3が設定されている。また、目標乾燥度は、数値が高くなるほど、より乾燥の度合が高くなる。つまり、本例ではD5が最も運転時間が長くなるランクであり、D1が最も運転時間が短くなるランクとなっている。
 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。
It should be noted that the initial value D3 is set in the state of driving for the first time. Moreover, the degree of drying becomes higher as the numerical value becomes higher. That is, in this example, D5 is the rank with the longest operation time, and D1 is the rank with the shortest operation time.
Further, the coefficients a and b for each rank of the application rank Dx are stored in the storage unit 7d in the control circuit 7, and when the rank goes up and down by evaluation information by the user described later, The coefficients a and b are read and used for the calculation.
 また、図9(a)を参照すると、判定カウントテーブルの更新する値とは、赤外線センサー6が検知した被乾燥物Rが設けられている適用エリアの大きさ「大」「中」「小」と、被乾燥物Rの乾燥の容易度「ノーマル」「乾燥容易」で分けられている、6つパターン化された被乾燥物Rの状況(「エリア大、ノーマル」「エリア大、乾燥容易」「エリア中、ノーマル」「エリア中、乾燥容易」「エリア小、ノーマル」「エリア小、乾燥容易」)に対してカウント値が設定されている。
 そして、このカウント値は、後述するステップS41とステップS31においてカウントが変更され、このカウントに基づきステップS42~S43とステップS32~S33において、被乾燥物Rの量と被乾燥物Rの乾燥し易さの度合などの条件ごとに、図9(b)で示す適用ランクDxの変更が判断される。
Also, referring to FIG. 9A, the value to be updated in the determination count table is the size “large”, “medium”, and “small” of the application area where the object to be dried R detected by the infrared sensor 6 is provided. And the status of the object to be dried R divided into “normal” and “easy to dry” (“area large, normal”, “area large, easy to dry”). Count values are set for “area, normal”, “area, easy to dry”, “area small, normal”, “area small, easy to dry”).
The count value is changed in steps S41 and S31, which will be described later. Based on this count, in step S42 to S43 and steps S32 to S33, the amount of the object R to be dried and the object R to be dried are easily dried. A change in the application rank Dx shown in FIG. 9B is determined for each condition such as the degree of the degree.
 図7に戻ると、まず、ステップS2では、赤外線センサー6及びこの赤外線センサー6が取り付けられている風向可変手段1を駆動し、除湿空気を送風可能なエリアのます目ごとの表面温度を測定してステップS3に移行する。
 尚、赤外線センサー6の初期動作は、除湿装置5やファンモーター2aの駆動前又は駆動と同時に行ってもよい。
Returning to FIG. 7, first, in step S <b> 2, the infrared sensor 6 and the wind direction varying means 1 to which the infrared sensor 6 is attached are driven, and the surface temperature of each area where the dehumidified air can be blown is measured. Then, the process proceeds to step S3.
The initial operation of the infrared sensor 6 may be performed before or simultaneously with the driving of the dehumidifying device 5 and the fan motor 2a.
 ステップS3では、ステップS2で測定したます目ごとの表面温度から、被乾燥物Rが位置しているます目(エリア)を推定し、このます目の数m1(図6で示すBの部分(塗潰されている部分)のます目の数)をカウントして、ステップS4に移行する。被乾燥物Rが位置するます目の推定基準は、周囲のます目より温度が低い位置を対象にしてもよく、また、所定の温度以下のます目を対象にしても良い。
 尚、この被乾燥物Rが位置するます目は、除湿運転時に風向可変手段1により積極的に除湿空気を吹き付ける吹き分けエリアとなる。
In step S3, the square (area) where the material to be dried R is located is estimated from the surface temperature of each square measured in step S2, and the number m1 of this square (the portion B shown in FIG. 6 ( The number of squares of the painted portion) is counted, and the process proceeds to step S4. The estimation standard of the squares where the material to be dried R is located may be for a position where the temperature is lower than that of the surrounding squares, or may be for the squares below a predetermined temperature.
Note that the first place where the material to be dried R is located is a blowing area in which dehumidified air is positively blown by the air direction varying means 1 during the dehumidifying operation.
 次に、ステップS4では、ステップS3でカウントしたます目の数m1に基づき、適用ランクDxの適用エリアを決定して、ステップS5へ移行する。つまり、このステップでは、被乾燥物Rの量をみている。ます目の数m1が多ければ多いほど、洗濯物が占めるます目のエリアが大きいことから、被乾燥物Rが多いと判断できる。
 本実施の形態では、適応エリアをます目の数に応じて「大(b≦m1)」「中(a≦m1<b)」「小(m1<a)」の3段階に分けられている(a<b)。
Next, in step S4, the application area of the application rank Dx is determined based on the number m1 of the squares counted in step S3, and the process proceeds to step S5. That is, in this step, the amount of the object to be dried R is observed. It can be judged that there are many to-be-dried objects R, since there are so many areas of the eyes which a laundry occupies, so that there are many number m1 of eyes.
In the present embodiment, the adaptation area is divided into three stages of “large (b ≦ m1)”, “medium (a ≦ m1 <b)”, and “small (m1 <a)” according to the number of eyes. (A <b).
 次に、ステップS5及びステップS6において、所定の時間、除湿運転を行う。
 本実施の形態では、除湿運転を60分間行い(ステップS6)、ステップS7に移行する。尚、この除湿運転の間に、赤外線センサー6を用いて10分おきに被乾燥物Rが位置するます目である吹き分けエリアの乾燥の度合いを計測し、乾燥と判断されたます目に、乾燥カウントを1ポイント加算する(ステップS5)。
 このます目への乾燥カウントの加算は、被乾燥物Rの乾燥度合を判断する為に用いるものであり、乾燥カウントがより多く加算されたます目ほど、当該ます目の位置にある被乾燥物Rの乾燥が進んでいると判断できる。
Next, in step S5 and step S6, the dehumidifying operation is performed for a predetermined time.
In the present embodiment, the dehumidifying operation is performed for 60 minutes (step S6), and the process proceeds to step S7. During this dehumidifying operation, the degree of drying in the blowing area, which is the first place where the material to be dried R is located, is measured every 10 minutes using the infrared sensor 6, and it is judged to be dry. One point is added to the dry count (step S5).
This addition of the dry count to the first eye is used to determine the degree of dryness of the object R to be dried. The more the dry count is added, the more the object to be dried at the position of the right eye. It can be judged that drying of R is progressing.
 ステップS7では、乾燥カウントが所定のポイント以上加算されたます目の数m2を計数して、ステップS8に移行する。本実施の形態では、2ポイント以上加算されたます目の数を計数している。つまり、乾燥が進んだ部分を計数するもので、図6(a)から図6(b)への過程で減少したBの部分のます目が対象となる。
 ステップS8では、m2/m1を計数し、所定の値以上であれば、ステップS9に移行して適用ランクDxの被乾燥物Rの乾燥容易度を「乾燥容易」に切り替えて、ステップ10に移行する。
In step S7, the number m2 of squares to which the dry count is added by a predetermined point or more is counted, and the process proceeds to step S8. In the present embodiment, the number of squares added with two or more points is counted. That is, the portion where the drying has progressed is counted, and the first portion of the portion B decreased in the process from FIG. 6A to FIG.
In step S8, m2 / m1 is counted, and if it is equal to or greater than the predetermined value, the process proceeds to step S9, the degree of dryness of the dried object R of the application rank Dx is switched to “easy to dry”, and the process proceeds to step 10. To do.
 また、m2/m1の値が、所定の値未満であれば、適用ランクDxの被乾燥物Rの乾燥容易度を「ノーマル」のままで、ステップS10に移行する。尚、本実施の形態において、8割以上の乾燥であれば「乾燥容易」と判断するように、m2/m1の判断基準値を0.8に設定してある。
 つまり、このステップS8では、干してある被乾燥物Rの乾き易さの度合を判定するステップとなっている。つまり、所定時間内に被乾燥物Rが乾いたとされるm2の数がおおくなればなるほど、乾きやすい被乾燥物Rといえる。
On the other hand, if the value of m2 / m1 is less than the predetermined value, the process proceeds to step S10 while keeping the ease of drying of the material R to be dried having the application rank Dx as “normal”. In the present embodiment, the determination reference value of m2 / m1 is set to 0.8 so that it is determined as “easy to dry” if it is 80% or more dry.
That is, in this step S8, it becomes a step which determines the degree of the ease of drying of the to-be-dried thing R dried. That is, it can be said that it becomes the to-be-dried material R which is easy to dry, so that the number of m2 with which the to-be-dried material R dries within the predetermined time increases.
 次に、ステップS10では、所定の時間(本実施の形態では、10分に設定)毎に湿度センサー10により検知される雰囲気相対湿度を判定し、あらかじめ設定された相対湿度(本例では50%以下)を検知するまで湿度検知が続けられる(ステップS11)。
 そして、予め設定された相対湿度に達すると、ステップS12に移行する。
 ステップS12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S13に移行する。そして、ステップS13では、検出温度Tと運転時間t1の積を計算して、ステップS14に移行する。
Next, in step S10, the ambient relative humidity detected by the humidity sensor 10 is determined every predetermined time (in the present embodiment, set to 10 minutes), and a preset relative humidity (50% in this example) is determined. The humidity detection is continued until the following is detected (step S11).
When the relative humidity set in advance is reached, the process proceeds to step S12.
In step S12, the operation time t1 from the start of operation when the atmospheric relative humidity (indoor air humidity) falls below 50% and the detected temperature T that is the atmospheric temperature (indoor air temperature) detected by the temperature sensor 9 are set. Then, the process proceeds to step S13. In step S13, the product of the detected temperature T and the operation time t1 is calculated, and the process proceeds to step S14.
 次に、ステップS14では、係数Dを算出してステップS15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して、ステップS15に移行する。『D=a×(T×t1)^b』(「^」は累乗を表す。)
 ここで、係数aと係数bは、S2~S9で選択した適用ランクDxに対応する値(図8)が用いられる。
Next, in step S14, the coefficient D is calculated, and the process proceeds to step S15.
The coefficient D is one of the variables that change the drying operation time of the clothes drying operation. The coefficient D is calculated by the following equation obtained through experiments, and the process proceeds to step S15. “D = a × (T × t1) ^ b” (“^” represents a power)
Here, as the coefficients a and b, values corresponding to the application rank Dx selected in S2 to S9 (FIG. 8) are used.
 次に、ステップS15において、ステップS14で求めた係数Dを用いて、残りの除湿運転時間Yを実験により求められた式『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S16に移行する。 Next, in step S15, using the coefficient D obtained in step S14, the remaining dehumidifying operation time Y is calculated by the equation “Y = t1 × (DT / 100)” obtained by experiment, and the remaining The dehumidifying operation time Y is determined, and the process proceeds to step S16.
 以降、使用者が運転を停止しなければ、残りの除湿運転時間Yが経過するまで衣類乾燥運転を行うが、ステップS16では運転時間がZに到達したか否かを判定している。運転時間Zは洗濯物の乾燥がある程度すすむ時間で実験値により設定されており、運転時間Z以降、使用者による衣類の乾燥度の評価が有効となっている。(使用者の使用形態から衣類の乾燥度の評価を得る。)
 ステップS16で運転時間がZに到達すると、ステップS17に移行する。
Thereafter, if the user does not stop the operation, the clothes drying operation is performed until the remaining dehumidifying operation time Y elapses. In step S16, it is determined whether or not the operation time has reached Z. The driving time Z is a time for drying of the laundry to some extent and is set by an experimental value. After the driving time Z, the evaluation of the dryness of the clothes by the user is effective. (Evaluation of the dryness of clothing is obtained from the usage pattern of the user.)
When the operation time reaches Z in step S16, the process proceeds to step S17.
 ここで、所定の運転時間Zの経過を条件に、ステップS17以降の処理を有効にしているが、これは、衣類乾燥運転中の運転スイッチ8の誤操作などによる運転停止を、ステップS17以降で実行する適用ランクDxを変更する為に用いる衣類の乾燥度合いに対する評価から除外する為であり、本実施の形態ではY>Zとなるように設定されている。
 例えば、ステップS16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。
Here, the processing after step S17 is validated on the condition that the predetermined operation time Z has elapsed. This is because the operation stop due to erroneous operation of the operation switch 8 during the clothes drying operation is executed after step S17. This is for excluding the evaluation of the dryness of the clothing used for changing the application rank Dx to be performed, and in the present embodiment, Y> Z is set.
For example, when the clothes drying operation is started shortly after the start of the clothes drying operation by configuring Step S16, the evaluation on the degree of drying in a state where the clothes are hardly dried may be excluded. It is possible to prevent erroneous determination and improve determination accuracy.
 次に、ステップS17以降は、使用者による衣類の乾燥度の評価を行うフローである。
 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。
Next, step S17 and subsequent steps are a flow for evaluating the dryness of clothes by the user.
In the present embodiment, the evaluation on the degree of dryness of the user's clothing is estimated by looking at the timing when the user stops driving, that is, when the user operates the operation switch 8.
 ステップS17では、使用者が運転スイッチを操作することにより、除湿運転時間Yが経過する前に運転停止されたか否かを判定する。
 本来であれば、ステップS15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S18を経て、ステップS19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S18に移行する前に運転を停止した場合には、ステップS31に移行する。
In step S17, it is determined whether or not the operation is stopped before the dehumidifying operation time Y elapses when the user operates the operation switch.
Originally, the clothes drying operation is completed in step S19 through step S18 for determining whether or not the remaining dehumidifying operation time Y calculated in step S15 has been reached.
However, when the user confirms the degree of drying of the laundry before the dehumidifying operation time Y elapses, and determines that the subsequent drying operation is unnecessary and stops the operation before proceeding to step S18, Control goes to step S31.
 ここで記憶部7dには、判定カウントを設けており、上記の通り推測する使用者の衣類の乾燥度合いに対する評価によりカウントの増減を行っている。尚、判定カウントの初期値は0としている。
 ステップS31では、S2~S9で選択した更新する設定カウントテーブルの対象の値である判定カウントの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S32に移行する。
Here, the storage unit 7d is provided with a determination count, and the count is increased or decreased by evaluating the user's clothing dryness estimated as described above. Note that the initial value of the determination count is 0.
In step S31, 1-point subtraction of the determination count that is the target value of the setting count table to be updated selected in S2 to S9 is performed, the result is stored in the storage unit 7d, and the process proceeds to step S32.
 ステップS32では、当該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」)以下であるかどうかを判定している。
 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。
In step S32, it is determined whether or not the cumulative count of the determination count is equal to or less than a predetermined numerical value (“−2” in the present embodiment).
In the present embodiment, it is determined whether the user has stopped the operation twice before the remaining dehumidifying time Y elapses in the present and past clothes drying operations. That is, in addition to whether or not the user intends to eliminate the operation until the dehumidifying time Y, erroneous determination due to erroneous input or mischief other than the user is prevented.
 その後、ステップS33に移行して、S2~S9で選択した今回の衣類乾燥運転の被乾燥物Rの状況に対応する適用ランクDxのランクを一つ下げ、次回の運転時に適用するランクを決定する。また同時に判定カウントをリセットする。
 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。
Thereafter, the process proceeds to step S33, and the rank of the application rank Dx corresponding to the condition of the object R to be dried of the current clothes drying operation selected in S2 to S9 is lowered by one, and the rank applied in the next driving is determined. . At the same time, the determination count is reset.
As described above, when the user stops the operation before the remaining dehumidifying operation time Y elapses, the dehumidifying operation time Y is corrected so as to be shortened during the subsequent operation.
 尚、本実施の形態において、ステップS32にて、判定カウントの累積カウントと数を「-2」としたが、係数Dランクを変化しやすく設定するのであれば累積カウントと数を「-1」とすればよく、また、Dランクを変化し難く設定するのであれば累積カウントと数を「-2」より小さい値に設定すればよい。
 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。
In this embodiment, the cumulative count and number of determination counts are set to “−2” in step S32. However, if the coefficient D rank is easily set, the cumulative count and number is set to “−1”. In addition, if the D rank is set to be difficult to change, the cumulative count and number may be set to a value smaller than “−2”.
Further, when the stop is performed before the remaining dehumidifying time Y, the determination count is subtracted by one point. However, 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.
 次に、ステップS17において、使用者により、残りの除湿時間Yが経過する前に運転停止されなかった場合、ステップS15にて算出された時間Yに到達するか否かを、ステップS18にて判定する。
 ステップS18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S19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S20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S18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S17に移行する。
Next, in step S17, if the user has not stopped the operation before the remaining dehumidifying time Y has elapsed, it is determined in step S18 whether or not the time Y calculated in step S15 has been reached. To do.
In step S18, when the operation end condition is met (when time Y has elapsed), the process proceeds to step S19, and the clothes drying operation is once ended. Thereafter, in step S20, the state is internally shifted to a standby state. The standby state is a state where dehumidification and air blowing are stopped.
In step S18, when the operation end condition is not met (when time Y has not elapsed), the process proceeds to step S17.
 この待機状態には、制限時間を設けてあり、ステップS22において所定時間を経過したかどうかを判定する。待機状態で所定時間を経過すると、ステップS23に移行して、運転を終了する。この制限時間は、本実施の形態では、5時間としている。
 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S21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S23に移行する前に運転を再開した場合には、ステップS41に移行する。
In this standby state, a time limit is provided, and it is determined whether or not a predetermined time has elapsed in step S22. When a predetermined time elapses in the standby state, the process proceeds to step S23 and the operation is terminated. This time limit is 5 hours in the present embodiment.
Here, when the dehumidifier is in the standby state, it is determined in step S21 whether the user has pressed the operation switch 8 again to start the clothes drying operation. The fact that the operation has started again means that the user has confirmed the degree of drying of the laundry and determined that the drying operation is necessary again. If the operation is resumed before proceeding to step S23, step S41 is performed. Migrate to
 ステップS41では、S2~S9で選択した更新する設定カウントテーブルの対象の値である判定カウントを1ポイント積算して、ステップS42に移行する。尚この結果は、記憶部7dに記憶される。
 そして、ステップS42では、当該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。
In step S41, the determination count which is the target value of the setting count table to be updated selected in S2 to S9 is added by one point, and the process proceeds to step S42. This result is stored in the storage unit 7d.
In step S42, it is determined whether or not the cumulative count 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.
 その後S43に移行して、S2~S9で選択した今回の衣類乾燥運転の被乾燥物Rの状況に対応する適用ランクDxを1つ上げ、次回の運転時に適用するランクを決定する。また同時に判定カウントをリセットし、ステップS44に移行して、追加の衣類乾燥運転を行う。
 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。
Thereafter, the process proceeds to S43, where the application rank Dx corresponding to the condition of the object R to be dried in the current clothes drying operation selected in S2 to S9 is increased by 1, and the rank applied in the next operation is determined. At the same time, the determination count is reset, and the process proceeds to step S44 to perform an additional clothes drying operation.
As described above, when the user restarts the operation during the standby state, the operation time is corrected in a direction in which the operation time is extended.
 以上のステップS17以降の制御フローを次の通りまとめる。
(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)。
The control flow after step S17 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. In other words, it was determined that there was no problem with the remaining dehumidification time as set. Even after the next operation, 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).
(3) After performing dehumidification until the remaining dehumidifying operation time Y, the user performs additional operation.
Presumed that the user judged that the dehumidification was insufficient. After the next operation, the remaining dehumidifying operation time Y is made longer than this time (changed by increasing the application rank Dx).
 ここで、本実施の形態においては、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、これを評価情報の入力とみなし、通常動作を行う中で運転時間の補正につながる例を説明したが、この限りでなく、図4に示すような乾燥度評価スイッチ11を設けて、使用者に積極的に評価情報を入力してもらっても良い。
 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。
Here, in the present embodiment, 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. However, the present invention is not limited to this, and a dryness evaluation switch 11 as shown in FIG. 4 is provided to actively support the user. Evaluation information may also be input.
When the user inputs a dryness evaluation using the dryness evaluation switch 11, the above-mentioned (1) to (3) correspond to the evaluation “too dry” (1), and the evaluation “just right” "Corresponds to (2), and the evaluation" insufficient drying "corresponds to (3).
 以上のように本実施の形態によれば、被乾燥物Rである洗濯物の乾燥度合いについて、使用者の衣類の乾燥度合いに対する評価により、制御回路7で決定された運転時間に対し補正をかけ、補正後の運転時間で運転を制御する。
 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。
As described above, according to the present embodiment, the degree of drying of the laundry that is the object to be dried R is corrected with respect to the operation time determined by the control circuit 7 by evaluating the degree of drying of the user's clothing.
