　また、湿度センサ２２は室内の湿度を検知するものであれば、本体６の外部に設けられてもよく、風路３以外に設けられてもよい。例えば、加湿対象空間内に設置されてもよい。また、操作手段２０に備えられ、操作手段２０が検知湿度を取得するようにしてもよい。また、加湿装置１００および操作手段２０以外の外部機器を温度センサとして機能させてもよい。 Further, the humidity sensor 22 may be provided outside the main body 6 or provided outside the air path 3 as long as it detects the humidity in the room. For example, you may install in the humidification object space. Further, the operation unit 20 may be provided so that the operation unit 20 acquires the detected humidity. Further, an external device other than the humidifying device 100 and the operation means 20 may function as a temperature sensor.
　また、熱交換換気装置へ本発明を適用する場合には、上記の例に加えて、室内吸込口と全熱交換器を連通する排気風路内に湿度センサを設置してもよい。また、非熱交換換気装置へ本発明を適用する場合には、上記の例に加えて、室内吸込口と室外吐出口を連通する排気風路内に湿度センサを設置してもよい。また、操作手段２０は、図１に示すようなリモコンではなく、本体６に備えつけられた操作スイッチであってもよい。 In addition, when the present invention is applied to a heat exchange ventilator, in addition to the above example, a humidity sensor may be installed in the exhaust air passage connecting the indoor suction port and the total heat exchanger. When the present invention is applied to a non-heat exchange ventilator, in addition to the above example, a humidity sensor may be installed in the exhaust air passage that connects the indoor suction port and the outdoor discharge port. Further, the operation means 20 may be an operation switch provided in the main body 6 instead of the remote controller as shown in FIG.
　また、温度センサ２３は加湿エレメント１７を通過する前の空気の温度を検知できればよい。したがって、温度センサ２３は、本体６の外部に設けられてもよく、風路３以外に設けられてもよい。例えば、室内循環型の加湿装置へ本発明を適用する場合は、加湿対象空間内に温度センサを設置してもよい。また、操作手段２０に温度センサを設けてもよい。また、制御部１９が、室内の温度と天井裏の温度との差を考慮した温度補正を行ってもよい。加湿装置１００および操作手段２０以外の外部機器を温度センサとして機能させてもよい。 The temperature sensor 23 only needs to be able to detect the temperature of the air before passing through the humidifying element 17. Therefore, the temperature sensor 23 may be provided outside the main body 6 or may be provided other than the air passage 3. For example, when the present invention is applied to an indoor circulation type humidifier, a temperature sensor may be installed in the humidification target space. Further, a temperature sensor may be provided in the operation means 20. Further, the control unit 19 may perform temperature correction in consideration of the difference between the indoor temperature and the ceiling temperature. An external device other than the humidifier 100 and the operation means 20 may function as a temperature sensor.
　また、熱交換換気装置へ本発明を適用する場合は、室内吸込口と全熱交換器を連通する排気風路内に設置された温度センサと、室外吸込口と全熱交換器を連通する給気風路内に設置された温度センサと、全熱交換器の熱交換効率から、加湿エレメント１７を通過する前の空気の温度を算出するようにしてもよい。また、加湿装置１００および操作手段２０以外の外部機器を温度センサとして機能させてもよい。 In addition, when the present invention is applied to a heat exchange ventilator, a temperature sensor installed in an exhaust air passage that communicates the indoor suction port and the total heat exchanger, and an air supply that communicates the outdoor suction port and the total heat exchanger. You may make it calculate the temperature of the air before passing through the humidification element 17 from the temperature sensor installed in the air wind path, and the heat exchange efficiency of a total heat exchanger. Further, an external device other than the humidifying device 100 and the operation means 20 may function as a temperature sensor.
　また、非熱交換換気装置へ本発明を適用する場合は、室外吸込口と全熱交換器を連通する給気風路内に温度センサを設置してもよいし、室外に設置してもよい。また、加湿装置１００および操作手段２０以外の外部機器を温度センサとして機能させてもよい。 In addition, when the present invention is applied to a non-heat exchange ventilator, a temperature sensor may be installed in the air supply air passage that communicates the outdoor suction port and the total heat exchanger, or may be installed outside the room. Further, an external device other than the humidifying device 100 and the operation means 20 may function as a temperature sensor.
　次に、加湿エレメント１７に給水槽７から供給された水が十分浸透して拡散した後に、給水手段１１からの給水を停止し、シロッコファン４の回転により、吸込口１から吹出口２に向かう空気流を風路３内に発生させた場合に、加湿装置１００からの加湿量と加湿エレメント１７の保水率がどのように推移するかを説明する。図２は、加湿装置１００からの加湿量と加湿エレメント１７の保水率の時間的推移を示す図である。なお、本発明の実施の形態においては、加湿装置１００を選択風量「弱」で運転する場合は、選択風量「強」に比べ半分の風量が出るものとする。 Next, after the water supplied from the water supply tank 7 has sufficiently permeated into the humidifying element 17 and diffused, the water supply from the water supply means 11 is stopped, and the sirocco fan 4 rotates to move from the suction port 1 to the blowout port 2. How the humidification amount from the humidifier 100 and the water retention rate of the humidifying element 17 change when an air flow is generated in the air passage 3 will be described. FIG. 2 is a diagram showing the temporal transition of the humidification amount from the humidifier 100 and the water retention rate of the humidifying element 17. In the embodiment of the present invention, when the humidifier 100 is operated with the selected air volume “weak”, it is assumed that the air volume is half that of the selected air volume “strong”.
　ここで、図２（ａ）のグラフは、選択風量が「強」における給水停止後の加湿エレメント１７の保水率の推移を表し、図２（ｂ）のグラフは、選択風量が「強」における給水停止後の加湿装置１００からの加湿量の推移を表している。また、図２（ｃ）のグラフは、選択風量が「弱」における給水停止後の加湿エレメント１７の保水率の推移を表し、図２（ｄ）のグラフは、選択風量が「弱」における給水停止後の加湿装置１００からの加湿量の推移を表している。なお、横軸の時間は、給水停止後、シロッコファン４の回転を開始した時刻を０としている。 Here, the graph of FIG. 2A represents the transition of the water retention rate of the humidifying element 17 after the stop of water supply when the selected air volume is “strong”, and the graph of FIG. 2B is the graph when the selected air volume is “strong”. The transition of the humidification amount from the humidifier 100 after the water supply stop is shown. Moreover, the graph of FIG.2 (c) represents transition of the water retention rate of the humidification element 17 after the water supply stop when the selected airflow is "weak", and the graph of FIG.2 (d) shows the water supply when the selected airflow is "weak". The change of the humidification amount from the humidification apparatus 100 after a stop is represented. The time on the horizontal axis is 0 when the sirocco fan 4 starts rotating after the water supply is stopped.
　まず、選択風量が「強」の場合（すなわち図２（ａ），（ｂ）の場合）の加湿エレメント１７の保水率の水位および加湿装置１００からの加湿量の推移について説明する。時刻０の時点では、加湿エレメント１７の保水率は１００％、加湿装置１００からの加湿量は最大の１００％となっている。なお、加湿量は、加湿エレメント１７の全面が湿潤している状態かつ選択風量が「強」でシロッコファン４が運転された場合の加湿量を１００％としている。 First, the water level of the humidifying element 17 and the transition of the humidification amount from the humidifier 100 when the selected air volume is “strong” (that is, in the case of FIGS. 2A and 2B) will be described. At time 0, the moisture retention rate of the humidifying element 17 is 100%, and the humidification amount from the humidifying device 100 is 100%, which is the maximum. The humidification amount is 100% when the sirocco fan 4 is operated in a state where the entire surface of the humidification element 17 is wet and the selected air volume is “strong”.
　この後、シロッコファン４の回転に伴い、加湿エレメント１７に保水された水が気化され、保水率は徐々に減少していく。しかし、加湿エレメント１７の保水率が減少しても、しばらくの間（グラフでは、給水停止から２．０［ｈｒ］までの間）、加湿エレメント１７の全面が湿潤している状態を保つため、加湿装置１００からの加湿量自体は、ほぼ１００％を維持することになる。 After this, with the rotation of the sirocco fan 4, the water retained in the humidifying element 17 is vaporized, and the water retention rate gradually decreases. However, even if the water retention rate of the humidifying element 17 decreases, in order to keep the entire surface of the humidifying element 17 wet for a while (in the graph, from the stop of water supply to 2.0 [hr]), The humidification amount itself from the humidifier 100 is maintained at almost 100%.
　その後、加湿エレメント１７に保水された水の気化がさらに進むと、加湿エレメント１７の湿潤している面積が減少し始めることで、加湿装置１００からの加湿量が落ちてくる。加湿装置１００からの加湿量が落ちることで、加湿エレメント１７の保水率の低下は鈍化することになる。その後、加湿エレメント１７に保水された水の気化がさらに進むと、最終的には、保水率が０％となり（グラフでは、給水停止から３．０［ｈｒ］の時点）、加湿エレメント１７が完全に乾燥した状態となる。 Thereafter, when the water held in the humidifying element 17 is further vaporized, the humidified area of the humidifying element 17 starts to decrease, and the amount of humidification from the humidifying device 100 decreases. When the humidification amount from the humidifying device 100 decreases, the decrease in the water retention rate of the humidifying element 17 is slowed down. Thereafter, when the vaporization of the water retained in the humidifying element 17 further proceeds, the water retention rate finally becomes 0% (in the graph, 3.0 [hr] from the stop of water supply), and the humidifying element 17 is completely It will be in a dry state.
　次に、選択風量が「弱」の場合（すなわち図２（ｃ），（ｄ）の場合）の加湿エレメント１７の保水率の推移および加湿装置１００からの加湿量の推移について説明する。時刻０の時点では、加湿エレメント１７の保水率１００％、加湿装置１００からの加湿量は、風量が「強」の半分となるため、５０％となっている。 Next, the transition of the water retention rate of the humidifying element 17 and the transition of the humidification amount from the humidifier 100 when the selected air volume is “weak” (that is, in the case of FIGS. 2C and 2D) will be described. At time 0, the moisture retention rate of the humidifying element 17 is 100%, and the humidification amount from the humidifier 100 is 50% because the air volume is half of “strong”.
　その後、シロッコファン４の回転に伴い、加湿エレメント１７に保水された水が気化され、保水率は徐々に減少していく。しかし、加湿エレメント１７の保水率が減少しても、しばらくの間（グラフでは、給水停止から４．０［ｈｒ］までの間）、加湿エレメント１７の全面が湿潤している状態を保つため、加湿装置１００からの加湿量自体は、ほぼ一定を保つことになる。 Then, with the rotation of the sirocco fan 4, the water retained in the humidifying element 17 is vaporized, and the water retention rate gradually decreases. However, even if the water retention rate of the humidifying element 17 decreases, in order to keep the entire surface of the humidifying element 17 wet for a while (in the graph, from the stop of water supply to 4.0 [hr]), The humidification amount itself from the humidifier 100 is kept substantially constant.
　なお、選択風量が「強」の場合に比べ、加湿装置１００からの加湿量は半分となるため加湿エレメント１７の保水率の減少割合も半分となる。その結果、加湿エレメント１７の全面が湿潤している時間も２倍程度となる。 In addition, since the humidification amount from the humidifier 100 is halved as compared with the case where the selected air volume is “strong”, the reduction rate of the water retention rate of the humidification element 17 is also halved. As a result, the time during which the entire surface of the humidifying element 17 is wet is also about twice.
　その後、加湿エレメント１７に保水された水の気化がさらに進むと、加湿エレメント１７の湿潤している面積が減少し始めることで、加湿装置１００からの加湿量が落ちてくる。加湿装置１００からの加湿量が落ちることで、加湿エレメント１７の保水率の低下は鈍化することになる。 Thereafter, when the water held in the humidifying element 17 is further vaporized, the humidified area of the humidifying element 17 starts to decrease, and the amount of humidification from the humidifying device 100 decreases. When the humidification amount from the humidifying device 100 decreases, the decrease in the water retention rate of the humidifying element 17 is slowed down.
　その後、加湿エレメント１７に保水された水の気化がさらに進むと、最終的には、保水率が０％となり（グラフでは、給水停止から６．０［ｈｒ］の時点）、加湿エレメント１７が完全に乾燥した状態となる。 Thereafter, when the vaporization of the water retained in the humidifying element 17 further proceeds, the water retention rate eventually becomes 0% (in the graph, 6.0 [hr] from the stop of water supply), and the humidifying element 17 is completely It will be in a dry state.
　次に、ユーザーが操作手段２０を操作して加湿装置１００を運転させる場合の動作の一例について説明する。図３から図８は、実施の形態１にかかる加湿装置１００の制御部１９による制御動作の一例を示すフローチャートである。 Next, an example of the operation when the user operates the operation means 20 to drive the humidifier 100 will be described. FIGS. 3 to 8 are flowcharts illustrating an example of a control operation performed by the control unit 19 of the humidifier 100 according to the first embodiment.
　なお、ユーザーが操作手段２０を介して行う加湿装置１００の運転および停止操作には、操作手段２０に備えられた運転／停止ボタン（図示せず）を直接操作して実施される場合と、操作手段２０に備えられたスケジュール機能によって自動的に実施される場合とがある。 The operation and stop operation of the humidifier 100 performed by the user via the operation means 20 are performed by directly operating an operation / stop button (not shown) provided in the operation means 20, and In some cases, it may be automatically performed by a schedule function provided in the means 20.
　また、操作手段２０に備えられたスケジュール機能における次回の運転／停止スケジュール情報は、加湿装置１００の制御部１９へ定期的に送信されるものとする。なお、以下の図面に示すステップは、制御部１９が行う判断および制御を示している。なお、運転／停止スケジュール情報を含めた各種情報は、記憶部１６に記憶される。記憶部１６は、操作手段２０に設けられていてもよい。 Further, it is assumed that the next operation / stop schedule information in the schedule function provided in the operation means 20 is periodically transmitted to the control unit 19 of the humidifier 100. Note that the steps shown in the following drawings show the judgment and control performed by the control unit 19. Various information including the operation / stop schedule information is stored in the storage unit 16. The storage unit 16 may be provided in the operation unit 20.
　加湿装置１００への電源投入後に、図３に示すステップＳ１において、「乾燥タイマー」を「乾燥完了時間」に設定する初期化が行われ、図４に示すステップＳ１１に進む。本実施の形態１では、「乾燥完了時間」が「３．０ｈｒ」に設定されている。すなわち、ステップＳ１では、「乾燥タイマー」のカウント値が、「乾燥完了時間」である「３．０ｈｒ」に設定される。 After the power supply to the humidifier 100 is turned on, initialization to set the “drying timer” to “drying completion time” is performed in step S1 shown in FIG. 3, and the process proceeds to step S11 shown in FIG. In the first embodiment, “drying completion time” is set to “3.0 hr”. That is, in step S1, the count value of the “drying timer” is set to “3.0 hr” which is the “drying completion time”.
　なお、「乾燥タイマー」が「乾燥完了時間」以上となっている場合には、加湿エレメント１７が完全に乾燥していると判断されることとなる。また、「乾燥タイマー」が「乾燥完了時間」未満となっている場合には、加湿エレメント１７が湿潤していると判断されることとなる。「乾燥タイマー」の初期値に設定される「乾燥完了時間」は、予め決定される値であるが、操作手段２０にて変更可能としてもよい。 In addition, when the “drying timer” is equal to or longer than the “drying completion time”, it is determined that the humidifying element 17 is completely dried. When the “drying timer” is less than the “drying completion time”, it is determined that the humidifying element 17 is wet. The “drying completion time” set as the initial value of the “drying timer” is a value determined in advance, but may be changed by the operation means 20.
　ステップＳ１１において、「乾燥タイマー」のカウント値が「３．０ｈｒ」以上であるか判断される。「乾燥タイマー」が「３．０ｈｒ」以上であれば（ステップＳ１１，Ｙｅｓ）、ステップＳ１２へ進む。電源投入直後であれば、ステップＳ１において「乾燥タイマー」のカウント値が「３．０ｈｒ」に設定されているので、「３．０ｈｒ」以上となり、ステップＳ１２に進む。 In step S11, it is determined whether the count value of the “drying timer” is “3.0 hr” or more. If the “drying timer” is equal to or greater than “3.0 hr” (step S11, Yes), the process proceeds to step S12. If it is immediately after the power is turned on, the count value of the “drying timer” is set to “3.0 hr” in step S1, and therefore becomes “3.0 hr” or more, and the process proceeds to step S12.
　ステップＳ１２において、停止モードに設定してから、ステップＳ１３において、給水弁９を閉じ、シロッコファン４を停止させ、ステップＳ１７に進む。以下の説明において、給水弁９を閉じ、シロッコファン４を停止する制御モードを停止モードと称し、給水弁９を閉じ、シロッコファン４を回転させる制御モードを送風モードと称し、給水弁９を開き、シロッコファン４を回転させる制御モードを加湿モードと称す。 In step S12, the stop mode is set, and in step S13, the water supply valve 9 is closed, the sirocco fan 4 is stopped, and the process proceeds to step S17. In the following description, a control mode in which the water supply valve 9 is closed and the sirocco fan 4 is stopped is referred to as a stop mode, a control mode in which the water supply valve 9 is closed and the sirocco fan 4 is rotated is referred to as a blow mode, and the water supply valve 9 is opened. The control mode for rotating the sirocco fan 4 is referred to as a humidification mode.
　ステップＳ１１において、「乾燥タイマー」が「３．０ｈｒ」未満であれば（ステップＳ１１，Ｎｏ）、ステップＳ１４へ進む。ステップＳ１４において、送風モードに設定してから、ステップＳ１５において、給水弁９を閉じ、シロッコファン４を回転させて、ステップＳ１６において、「乾燥タイマー」のカウントを実施し、ステップＳ１７へ進む。　　　 In step S11, if the “drying timer” is less than “3.0 hr” (No in step S11), the process proceeds to step S14. In step S14, the air blowing mode is set, and then in step S15, the water supply valve 9 is closed and the sirocco fan 4 is rotated. In step S16, the “drying timer” is counted, and the process proceeds to step S17. *
　なお、ステップＳ１６において、「乾燥タイマー」は選択風量に応じてカウント方法を変更する。具体的には選択風量が「強」の場合は、１秒進むごとに１秒をカウントする。また、選択風量が「弱」の場合は、選択風量「強」の場合に比べ風量が半分となり、乾燥速度も半分になるため、２秒進むごとに１秒をカウントとする。すなわち、本実施の形態１における加湿エレメント１７は、選択風量が「強」で風量一定の場合は「３．０ｈｒ」経過で、「乾燥タイマー」が「３．０ｈｒ」をカウントする。選択風量が「弱」で風量一定の場合は「６．０ｈｒ」経過で、「乾燥タイマー」が「３．０ｈｒ」をカウントする。「乾燥タイマー」は、制御装置２５によってソフトウェア的に構成されてもよいし、制御装置２５とは別個のハードウェアとして構成されてもよい。 In step S16, the “drying timer” changes the counting method according to the selected air volume. Specifically, when the selected air volume is “strong”, 1 second is counted for every 1 second. Further, when the selected air volume is “weak”, the air volume is halved and the drying speed is also halved as compared with the case where the selected air volume is “strong”. Therefore, every second, 1 second is counted. That is, in the humidifying element 17 in the first embodiment, when the selected air volume is “strong” and the air volume is constant, “3.0 hr” has elapsed and the “drying timer” counts “3.0 hr”. When the selected air volume is “weak” and the air volume is constant, “6.0 hr” has elapsed and “dry timer” counts “3.0 hr”. The “drying timer” may be configured by software by the control device 25, or may be configured as hardware separate from the control device 25.
　また、ステップＳ１４に進むことは、加湿装置１００の運転時に乾燥運転が完了していないことを意味し、加湿装置１００の停止時に「乾燥タイマー」が「乾燥完了時間」（本実施の形態では「３．０ｈｒ」）となるまで、送風モードの動作を継続させることで、加湿エレメント１７を完全に乾燥させている。 Further, proceeding to step S14 means that the drying operation is not completed during the operation of the humidifying device 100, and the “drying timer” is set to the “drying completion time” (in this embodiment, “ The humidifying element 17 is completely dried by continuing the operation in the air blowing mode until 3.0 hr ").
　ステップＳ１７において、操作手段２０によってユーザーから加湿装置１００の運転操作がされていないか判定される。加湿装置１００の運転操作がされていなかった場合は（ステップＳ１７，Ｎｏ）、ステップＳ１１に戻る。一方、加湿装置１００の運転操作がされていた場合は（ステップＳ１７，Ｙｅｓ）、図５に示すステップＳ２１に進む。 In step S17, it is determined by the operation means 20 whether the user has operated the humidifier 100. When the operation of the humidifier 100 has not been performed (No at Step S17), the process returns to Step S11. On the other hand, when the operation of the humidifier 100 has been performed (step S17, Yes), the process proceeds to step S21 shown in FIG.
　ステップＳ２１において、加湿装置１００の制御モードが送風モードに設定され、ステップＳ２２において、給水弁９は閉じたままシロッコファン４が回転される。次に、ステップＳ２３において「乾燥タイマー」のカウントを実施し、ステップＳ２４において、操作手段２０によってユーザーから加湿装置１００の停止操作がされていないか判定される。 In step S21, the control mode of the humidifier 100 is set to the air blowing mode, and in step S22, the sirocco fan 4 is rotated while the water supply valve 9 is closed. Next, the “drying timer” is counted in step S23, and in step S24, it is determined whether or not the user has stopped the humidifying device 100 by the operation means 20.
　ステップＳ２４において、加湿装置１００の停止操作がされていた場合は（ステップＳ２４，Ｙｅｓ）、ステップＳ１１に戻る。一方、加湿装置１００の停止操作がされていなかった場合は（ステップＳ２４，Ｎｏ）、ステップＳ２５に進む。なお、ステップＳ２３における「乾燥タイマー」のカウントは、ステップＳ１６同様、選択風量に応じて、カウント方法を変更するものとする。 In step S24, when the operation of stopping the humidifier 100 has been performed (Yes in step S24), the process returns to step S11. On the other hand, when the stop operation of the humidifier 100 has not been performed (No at Step S24), the process proceeds to Step S25. Note that the counting of the “drying timer” in step S23 is changed according to the selected air volume as in step S16.
　ステップＳ２５において、送風モードになってからの時間が、一定時間である５分が経過したかを判断する。ステップＳ２５において、一定時間が経過していなかった場合は（ステップＳ２５，Ｎｏ）、ステップＳ２４の判断を繰り返す。一方、一定時間が経過している場合は（ステップＳ２５，Ｙｅｓ）、ステップＳ２６に進む。なお、ステップＳ２５での判断は、湿度センサ２２の検知値が安定するまで一定時間待つことが目的であり、加湿装置１００の設置環境によって時間は調整されるものとする。本実施の形態１では、一定時間を５分としているが、適宜変更可能としてもよく、待ち時間なし、すなわち一定時間を０としても構わない。また、ステップＳ１４からステップＳ１７を経て、最初にステップＳ２５へ進んだ場合、既に一定時間が経過している場合がある。この場合も即ステップＳ２６へ進むことになる。 In step S25, it is determined whether or not a fixed time of 5 minutes has elapsed since the air blowing mode was entered. In step S25, when the predetermined time has not elapsed (step S25, No), the determination in step S24 is repeated. On the other hand, if the predetermined time has elapsed (step S25, Yes), the process proceeds to step S26. The determination in step S25 is intended to wait for a certain period of time until the detected value of the humidity sensor 22 is stabilized, and the time is adjusted according to the installation environment of the humidifier 100. In the first embodiment, the fixed time is set to 5 minutes. However, it may be changed as appropriate, and there may be no waiting time, that is, the fixed time may be set to 0. Further, when the process proceeds from step S14 to step S17 to step S25 for the first time, a certain time may have already passed. Also in this case, the process immediately proceeds to step S26.
　ステップＳ２６において、「装置運転時の乾燥運転時間」を「０」に初期化し、図６に示すステップＳ３１に進む。 In step S26, “drying operation time during apparatus operation” is initialized to “0”, and the process proceeds to step S31 shown in FIG.
　ステップＳ３１において、「停止予定時刻までの残り時間」が、「装置運転時の乾燥運転時間」以上であるか判断される。「停止予定時刻までの残り時間」が「装置運転時の乾燥運転時間」以上であれば（ステップＳ３１，Ｙｅｓ）、ステップＳ３２へ進む。一方、「停止予定時刻までの残り時間」が「装置運転時の乾燥運転時間」未満であれば（ステップＳ３１，Ｎｏ）、ステップＳ３３へ進む。 In step S31, it is determined whether the “remaining time until the scheduled stop time” is equal to or greater than the “drying operation time during device operation”. If the “remaining time until the scheduled stop time” is equal to or greater than the “drying operation time during device operation” (step S31, Yes), the process proceeds to step S32. On the other hand, if the “remaining time until the scheduled stop time” is less than the “drying operation time during device operation” (step S31, No), the process proceeds to step S33.
　なお、ステップＳ３１において、「停止予定時刻までの残り時間」が「装置運転時の乾燥運転時間」未満であった場合、加湿装置１００が装置運転時の乾燥運転を実施中であることを意味する。また、ステップＳ２６を経て最初にステップＳ３１に到達した場合には、ステップＳ２６で「装置運転時の乾燥運転時間」を「０」に初期化しているので、ステップＳ３２に進むこととなる。 In step S31, when the “remaining time until the scheduled stop time” is less than the “drying operation time during device operation”, it means that the humidifier 100 is performing the drying operation during device operation. . In addition, when step S31 is reached first through step S26, "drying operation time during apparatus operation" is initialized to "0" in step S26, and the process proceeds to step S32.
　ステップＳ３２において、「装置運転時の乾燥運転時間」を以下の通り設定する。すなわち、選択風量が「強」の場合は、「装置運転時の乾燥運転時間」＝「適正加湿量キープ時間」－「乾燥タイマー」とする。選択風量が「弱」の場合は、「装置運転時の乾燥運転時間」＝（「適正加湿量キープ時間」－「乾燥タイマー」）×２とする。 In step S32, the “drying operation time during device operation” is set as follows. That is, when the selected air volume is “strong”, “drying operation time during device operation” = “appropriate humidification amount keeping time” − “drying timer”. When the selected air volume is “weak”, “drying operation time during device operation” = (“appropriate humidification amount keeping time” − “drying timer”) × 2.
　ここで、本実施の形態１における「適正加湿量キープ時間」は、図２（ｂ）において加湿エレメント１７が給水停止直後の加湿量を維持する「２．０ｈｒ」に設定しておく。なお、「適正加湿量キープ時間」は、停止予定時刻において加湿対象空間（室内）における湿度が適性に保つように設定されればよく、図２（ｂ）において、加湿量５０％で停止予定時刻における快適性が確保できる場合は、加湿量５０％をキープできる「２．５ｈｒ」に設定してもよい。 Here, the “appropriate humidification amount keeping time” in the first embodiment is set to “2.0 hr” in which the humidification element 17 maintains the humidification amount immediately after the water supply is stopped in FIG. The “appropriate humidification amount keeping time” may be set so that the humidity in the humidification target space (indoor) is kept appropriate at the scheduled stop time. In FIG. If the comfort level can be secured, it may be set to “2.5 hr” that can keep the humidification amount 50%.
　また、加湿モードから送風モードへ切り替わり、初めて本ステップＳ３２に入った場合、後述するステップＳ４６にて「乾燥タイマー」はクリアストップ、すなわち、０でカウント停止を経ているため、「装置運転時の乾燥運転時間」には、「適正加湿量キープ時間」が設定されていることになる。 In addition, when switching from the humidifying mode to the air blowing mode and entering this step S32 for the first time, the “drying timer” has been cleared in step S46, which will be described later, that is, the count is stopped at 0. In “operation time”, “appropriate humidification amount keeping time” is set.
　ステップＳ３３において、制御モードが加湿モードとなっているか送風モードとなっているか判断される。制御モードが加湿モードとなっていれば、図７に示すステップＳ４１へ進み、制御モードが送風モードとなっていれば、図８に示すステップＳ５１に進む。なお、図７に示すステップＳ４１からステップＳ４７までの動作は加湿モードでの動作であり、図８に示すステップＳ５１からステップＳ５７までの動作は送風モードでの動作となる。 In step S33, it is determined whether the control mode is the humidification mode or the ventilation mode. If the control mode is the humidification mode, the process proceeds to step S41 shown in FIG. 7, and if the control mode is the blow mode, the process proceeds to step S51 shown in FIG. The operation from step S41 to step S47 shown in FIG. 7 is an operation in the humidification mode, and the operation from step S51 to step S57 shown in FIG. 8 is an operation in the air blowing mode.
　まず、図７に示す加湿モードでの動作を説明する。ステップＳ４１において、「停止予定時刻までの残り時間」が、ステップＳ３２にて決定した「装置運転時の乾燥運転時間」未満になったか判断する。「停止予定時刻までの残り時間」が「装置運転時の乾燥運転時間」未満になった場合は（ステップＳ４１，Ｙｅｓ）、ステップＳ４２へ進む。一方、「停止予定時刻までの残り時間」が「装置運転時の乾燥運転時間」以上の場合は（ステップＳ４１，Ｎｏ）、ステップＳ４３へ進む。 First, the operation in the humidification mode shown in FIG. 7 will be described. In step S41, it is determined whether the “remaining time until the scheduled stop time” is less than the “drying operation time during device operation” determined in step S32. If the “remaining time until the scheduled stop time” is less than the “drying operation time during device operation” (step S41, Yes), the process proceeds to step S42. On the other hand, when the “remaining time until the scheduled stop time” is equal to or greater than the “drying operation time during operation of the apparatus” (No in step S41), the process proceeds to step S43.
　ステップＳ４２において、後述する運転可否決定テーブルを用いて、制御モードを移行して送風モードで運転してよいか否かが判断される。送風モードでの運転「不可」と判断された場合は（ステップＳ４２，Ｎｏ）、ステップＳ４３へ進む。一方、送風モードでの運転「可能」と判断された場合は（ステップＳ４２，Ｙｅｓ）、ステップＳ４４に進んで制御モードを送風モードへ切り替えた上で、ステップＳ３１へ戻る。 In step S42, it is determined whether or not it is possible to shift to the control mode and operate in the air blowing mode using an operation availability determination table described later. When it is determined that the operation in the air blowing mode is “impossible” (No at Step S42), the process proceeds to Step S43. On the other hand, when it is determined that the operation in the blow mode is “possible” (step S42, Yes), the process proceeds to step S44, the control mode is switched to the blow mode, and the process returns to step S31.
　図９は、実施の形態１にかかる加湿装置１００において用いられる運転可否決定テーブルを示す図である。運転可否決定テーブルでは、「停止予定時刻までの残り時間」と「検知湿度」と送風モードでの運転の可否とが関係づけられている。 FIG. 9 is a diagram illustrating an operation availability determination table used in the humidifier 100 according to the first embodiment. In the operation availability determination table, “remaining time until scheduled stop time”, “detected humidity”, and availability of operation in the air blowing mode are related.
　この運転可否決定テーブルを参照することで、具体的には、検知湿度が、送風モードから加湿モードへの切り替え判定に用いている第２の規定湿度である「目標湿度－５％」を下回った場合でも、「停止予定時刻までの残り時間」が短い場合（例えば３分）には、ユーザーの快適性が大きく損なわれることはないと判断し、送風モードでの運転を可能とするようにしている。 Specifically, the detected humidity falls below “target humidity −5%”, which is the second specified humidity used to determine whether to switch from the air blowing mode to the humidifying mode, by referring to this driving availability determination table. Even when the “remaining time until the scheduled stop time” is short (for example, 3 minutes), it is determined that the user's comfort will not be greatly impaired, and the operation in the air blowing mode is enabled. Yes.
　一方、「停止予定時刻までの残り時間」が長い場合（例えば、１ｈｒ）は、ユーザーの快適性を大きく損ねると判断し、「目標湿度－５％」を下回った場合は、送風モードでの運転を不可とするようにしている。 On the other hand, when the “remaining time until the scheduled stop time” is long (for example, 1 hr), it is judged that the user's comfort is greatly impaired, and when it falls below “target humidity −5%”, the operation in the air blowing mode is performed. To make it impossible.
　ステップＳ４３において、湿度センサ２２の検知湿度が「目標湿度＋５％」以上であるか判断する。検知湿度が「目標湿度＋５％」未満であれば（ステップＳ４３，Ｎｏ）、ステップＳ４５へ進む。検知湿度が「目標湿度＋５％」以上であれば（ステップＳ４３，Ｙｅｓ）、ステップＳ４４において制御モードを送風モードに変更した上で、ステップＳ３１へ戻る。 In step S43, it is determined whether the humidity detected by the humidity sensor 22 is equal to or higher than “target humidity + 5%”. If the detected humidity is less than “target humidity + 5%” (No in step S43), the process proceeds to step S45. If the detected humidity is “target humidity + 5%” or more (step S43, Yes), the control mode is changed to the air blowing mode in step S44, and then the process returns to step S31.
　なお、ステップＳ４２において、送風モードでの運転が「不可」となった場合、ステップＳ４３においては、必ず検知湿度が「目標湿度＋５％未満」の判定となり、ステップＳ４５へ進むことになる。また、目標湿度はユーザーが操作手段２０によって予め設定しているものとする。 If the operation in the air blowing mode becomes “impossible” in step S42, the detected humidity is always determined to be “target humidity + less than 5%” in step S43, and the process proceeds to step S45. In addition, it is assumed that the target humidity is set in advance by the operation means 20 by the user.
　ステップＳ４５において、シロッコファン４を回転したまま、給水弁９が開かれる。これにより、給水口１０から給水槽７に水が供給される。そして、給水槽７を経て加湿エレメント１７に水が供給される。この際、シロッコファン４が回転しているため、吸込口１から吸い込まれた空気が風路３内にある加湿エレメント１７を通過し吹出口２へ流れ室内へ送風される。加湿エレメント１７を空気が通過することにより、加湿エレメント１７上の水は気化し、加湿された空気を室内へ供給することができる。すなわち、加湿モードでの運転が行われる。 In step S45, the water supply valve 9 is opened while the sirocco fan 4 is rotating. Thereby, water is supplied from the water supply port 10 to the water supply tank 7. Then, water is supplied to the humidifying element 17 through the water supply tank 7. At this time, since the sirocco fan 4 is rotating, the air sucked from the suction port 1 passes through the humidifying element 17 in the air passage 3, flows to the outlet 2, and is blown into the room. When the air passes through the humidifying element 17, the water on the humidifying element 17 is vaporized, and the humidified air can be supplied into the room. That is, the operation in the humidification mode is performed.
　なお、本実施の形態１にかかる加湿装置１００では、加湿エレメント１７に、給水手段１１から塩素を含む水道水が直接供給されることで、加湿エレメント１７上でカビおよび雑菌が発生しにくい構造となっている。また、給水手段１１の給水能力は、加湿運転時の蒸発水量の３倍程度の水量を給水し得るものとし、給水槽７の容積および給水槽７の底面に形成される孔の密度は、給水槽７からオーバーフローしないよう設計されているものとする。また、仮に給水槽７の底面が目詰まりしてオーバーフローした場合には、排水槽１２でオーバーフローした水を受容する構造とすることで、機外への漏水を防止できる。 In the humidifying device 100 according to the first embodiment, tap water containing chlorine is directly supplied from the water supply means 11 to the humidifying element 17 so that mold and bacteria are unlikely to occur on the humidifying element 17. It has become. In addition, the water supply capacity of the water supply means 11 is such that it can supply an amount of water about three times the amount of evaporated water during the humidifying operation, and the density of the holes formed in the volume of the water supply tank 7 and the bottom surface of the water supply tank 7 is It is assumed that it is designed not to overflow from the water tank 7. In addition, if the bottom surface of the water supply tank 7 is clogged and overflows, leakage of water to the outside of the machine can be prevented by adopting a structure that receives the overflowed water in the drain tank 12.
　また、加湿モード中、加湿エレメント１７で気化されなかった加湿供給水の残水は排水槽１２へ流れる。残水は、この排水槽１２の底面に形成された排水口１４から本体６に設けられた排水接続口１３を通し排水される。また、本実施の形態１にかかる加湿装置１００では、加湿エレメント１７で気化されなかった残水が、加湿エレメント１７に循環しない構造となっているので、残水が機内に留まることでカビおよび雑菌が繁殖するような不具合が発生しにくい。また、残水が再利用されないので、カルキ成分が濃縮されることもない。 Also, during the humidification mode, the remaining water of the humidified feed water that has not been vaporized by the humidification element 17 flows into the drainage tank 12. The remaining water is drained from a drain port 14 formed in the bottom surface of the drain tank 12 through a drain connection port 13 provided in the main body 6. In addition, in the humidifying device 100 according to the first embodiment, since the residual water that has not been vaporized by the humidifying element 17 is not circulated to the humidifying element 17, mold and germs are caused by the residual water remaining in the machine. It is hard to generate the trouble that breeds. In addition, since the residual water is not reused, the chalk component is not concentrated.
　ステップＳ４６において、「乾燥タイマー」がクリアストップ、すなわち、０でカウント停止とされ、ステップＳ４７へ進む。ステップＳ４７において、操作手段２０によってユーザーから加湿装置１００の停止操作がされていないか判定される。加湿装置１００の停止操作がされていた場合は（ステップＳ４７，Ｙｅｓ）、ステップＳ１１へ戻る。一方、加湿装置１００の停止操作がされていなかった場合は（ステップＳ４７，Ｎｏ）、ステップＳ３１へ戻る。 In step S46, the “drying timer” is cleared, that is, the count is stopped when 0, and the process proceeds to step S47. In step S <b> 47, it is determined whether or not the user has stopped the humidifying device 100 by the operation unit 20. When the stop operation of the humidifier 100 has been performed (step S47, Yes), the process returns to step S11. On the other hand, when the operation of stopping the humidifier 100 has not been performed (No at Step S47), the process returns to Step S31.
　次に、ステップＳ３３にて送風モードと判定された場合の動作、すなわち図８に示す送風モードでの動作を説明する。ステップＳ５１において、「停止予定時刻までの残り時間」が、ステップＳ３２で設定された「装置運転時の乾燥運転時間」未満になったか判断する。「停止予定時刻までの残り時間」が「装置運転時の乾燥運転時間」未満になった場合は（ステップＳ５１，Ｙｅｓ）、ステップＳ５３へ進む。一方、「停止予定時刻までの残り時間」が「装置運転時の乾燥運転時間」以上の場合は（ステップＳ５１，Ｎｏ）、ステップＳ５２へ進む。 Next, the operation when it is determined as the air blowing mode in step S33, that is, the operation in the air blowing mode shown in FIG. 8 will be described. In step S51, it is determined whether the “remaining time until the scheduled stop time” is less than the “drying operation time during device operation” set in step S32. If the “remaining time until the scheduled stop time” is less than the “drying operation time during device operation” (step S51, Yes), the process proceeds to step S53. On the other hand, when the “remaining time until the scheduled stop time” is equal to or longer than the “drying operation time during device operation” (No in step S51), the process proceeds to step S52.
　ステップＳ５２において、湿度センサ２２の検知湿度が、第２の規定湿度である「目標湿度－５％」未満であるか判断される。検知湿度が「目標湿度－５％」以上であれば（ステップＳ５２，Ｎｏ）、ステップＳ５３へ進む。一方、検知湿度が「目標湿度－５％」未満であれば（ステップＳ５２，Ｙｅｓ）、ステップＳ５４に進んで制御モードを加湿モードへ変更の上、ステップＳ３１に戻る。 In step S52, it is determined whether the humidity detected by the humidity sensor 22 is less than “target humidity—5%” which is the second specified humidity. If the detected humidity is “target humidity−5%” or more (step S52, No), the process proceeds to step S53. On the other hand, if the detected humidity is less than “target humidity—5%” (step S52, Yes), the process proceeds to step S54, the control mode is changed to the humidification mode, and the process returns to step S31.
　なお、第２の規定湿度「目標湿度－５％」を、第１の規定湿度「目標湿度＋５％」よりも低い湿度に設定しているのは、検知湿度が目標湿度付近で上下した場合に、制御モードが加湿モードと送風モードとに頻繁に切り替わる、いわゆるチャタリングが発生することを抑えるためである。すなわち、チャタリングの発生を抑えることができるのであれば、第１の規定湿度と第２の規定湿度の大小関係は問わない。例えば、第１の規定湿度と第２の規定湿度を同じ湿度である「目標湿度」に設定した場合には、ステップＳ４３からステップＳ４４に進む際に、加湿モードでの動作を一定の時間継続させてから送風モードに変更するか否かの判断を行うように設定すれば、チャタリングの発生を抑えることができる。 Note that the second specified humidity “target humidity −5%” is set to a lower humidity than the first specified humidity “target humidity + 5%” when the detected humidity rises and falls near the target humidity. This is to suppress the occurrence of so-called chattering in which the control mode is frequently switched between the humidification mode and the air blowing mode. That is, as long as the occurrence of chattering can be suppressed, the magnitude relationship between the first specified humidity and the second specified humidity does not matter. For example, when the first specified humidity and the second specified humidity are set to the “target humidity” that is the same humidity, the operation in the humidification mode is continued for a certain time when the process proceeds from step S43 to step S44. If it is set so as to determine whether or not to change to the air blowing mode, chattering can be suppressed.
　また、ステップＳ５３からステップＳ５４に進む際に、送風モードでの動作を一定の時間継続させてから加湿モードに変更するか否かの判断を行うように設定すれば、チャタリングの発生を抑えることができる。加湿モードおよび送風モードを継続させる一定の時間の一例には、３０分が挙げられる。 Further, when the process proceeds from step S53 to step S54, if it is set to determine whether or not to change to the humidification mode after continuing the operation in the air blowing mode for a certain time, the occurrence of chattering can be suppressed. it can. An example of the fixed time for continuing the humidification mode and the air blowing mode is 30 minutes.
　ステップＳ５３において、ステップＳ４２と同様に、図９に示す運転可否決定テーブルを用いて送風モードでの運転の可否が判断される。送風モードの運転「可能」と判断された場合は（ステップＳ５３，Ｙｅｓ）、ステップＳ５５へ進む。一方、送風モードの運転「不可」と判断された場合は（ステップＳ５３，Ｎｏ）、ステップＳ５４にて制御モードを加湿モードへ切り替えた上で、ステップＳ３１へ戻る。これらの送風モードでの運転の可否は、「停止予定時刻までの残り時間」および「検知湿度」に基づいて、ユーザーの快適性を大きく損ねるか否かを考慮の上で判断していると換言できる。 In step S53, whether or not the operation in the air blowing mode is possible is determined using the operation availability determination table shown in FIG. If it is determined that the operation in the air blowing mode is “possible” (step S53, Yes), the process proceeds to step S55. On the other hand, when it is determined that the operation in the air blowing mode is “impossible” (No in step S53), the control mode is switched to the humidification mode in step S54, and then the process returns to step S31. In other words, whether or not to operate in these ventilation modes is determined based on whether or not the user's comfort is greatly impaired based on the “time remaining until the scheduled stop time” and “detected humidity”. it can.
　なお、ステップＳ５２において、検知湿度が「目標湿度－５％」以上となった場合、ステップＳ５３においては、必ず「送風モードでの運転可能」の判定となり、ステップＳ５５へ進むことになる。 In step S52, if the detected humidity is equal to or higher than “target humidity—5%”, in step S53, it is always determined that “operation in the air blowing mode is possible”, and the process proceeds to step S55.
　ステップＳ５５において、シロッコファン４を回転したまま、給水弁９が閉じられ、ステップＳ５６へ進む。なお、本ステップＳ５５にて給水弁９が閉じられたことで、給水口１０から給水槽７への給水が止まる。すなわち、加湿エレメント１７への給水が止まる。 In step S55, the water supply valve 9 is closed while the sirocco fan 4 is rotating, and the process proceeds to step S56. In addition, the water supply valve 9 is closed in this step S55, whereby the water supply from the water supply port 10 to the water supply tank 7 is stopped. That is, the water supply to the humidifying element 17 stops.
　この結果、加湿エレメント１７では気化蒸発が進むにつれ、図２に示した通りある一定時間は加湿量を維持するが、加湿エレメント１７が徐々に乾燥すると、最終的には加湿された空気が供給されなくなる。なお、本実施の形態１にかかる加湿装置１００においては、空気清浄フィルタ２１が備え付けられているため、加湿エレメント１７が完全に乾燥した状態になった後の送風モード時は、空気清浄運転を実施していると言える。 As a result, as the vaporization and evaporation proceeds in the humidifying element 17, the humidification amount is maintained for a certain period of time as shown in FIG. 2, but when the humidifying element 17 is gradually dried, the humidified air is finally supplied. Disappear. In addition, in the humidification apparatus 100 concerning this Embodiment 1, since the air purifying filter 21 is equipped, air cleaning operation is implemented at the time of the ventilation mode after the humidification element 17 will be in the completely dried state. I can say that.
　ステップＳ５６において、「乾燥タイマー」のカウントを開始し、ステップＳ５７へ進む。なお、加湿モードから送風モードへ切り替わり、初めて本ステップＳ５６に入った場合、ステップＳ４６のクリアストップを経ているため、「乾燥タイマー」は０からのカウントを開始することになる。送風モードを継続している中で、本ステップＳ５６に入った場合は、「乾燥タイマー」はカウントを継続することになる。また、ステップＳ５６における「乾燥タイマー」のカウントは、ステップＳ１６同様、選択風量に応じて、カウント方法を変更するものとする。 In step S56, the “drying timer” starts counting, and the process proceeds to step S57. In addition, when it switches from humidification mode to ventilation mode and enters this step S56 for the first time, since it has passed the clear stop of step S46, "drying timer" will start the count from 0. When the present mode is entered while the air blowing mode is continued, the “drying timer” continues counting. Further, the counting of the “drying timer” in step S56 is changed in accordance with the selected air volume as in step S16.
　ステップＳ５７において、操作手段２０によってユーザーから加湿装置１００の停止操作がされていないか判定される。加湿装置１００の停止操作がされていた場合は（ステップＳ５７，Ｙｅｓ）、ステップＳ１１へ進む。一方、加湿装置１００の停止操作がされていなかった場合は（ステップＳ５７，Ｎｏ）、ステップＳ３１へ戻る。 In step S57, it is determined by the operation means 20 whether the user has stopped the humidifying device 100. If the operation of stopping the humidifier 100 has been performed (Yes at Step S57), the process proceeds to Step S11. On the other hand, when the operation of stopping the humidifier 100 has not been performed (No at Step S57), the process returns to Step S31.
　以上のように、本実施の形態１にかかる加湿装置１００は、ステップＳ３２において、図２に示した加湿エレメント１７の特性に基づき、「適正加湿量キープ時間」を設定の上、「装置運転時の乾燥運転時間」を算出し、さらに、ステップＳ４１において、「停止予定時刻までの残り時間」が「装置運転時の乾燥運転時間」未満になった場合には、ステップＳ４２を経て、加湿モードから送風モードへの切り替えが可能となるため、加湿装置１００の停止予定時刻を待たずに乾燥運転を開始することができる。制御部１９が、送風モードにおける加湿エレメント１７の乾燥に必要な時間に基づいて、停止予定時刻前の送風モードでの運転時間と、停止予定時刻後の送風モードでの運転時間を設定するので、加湿装置１００の停止後の乾燥運転時間を極力抑制できるとともに、停止予定時刻における適正湿度も確保可能となる。 As described above, the humidifying device 100 according to the first embodiment sets the “appropriate humidification amount keeping time” based on the characteristics of the humidifying element 17 shown in FIG. In step S41, when the “remaining time until the scheduled stop time” is less than the “dry operation time during device operation”, the process proceeds to step S42 to start the humidification mode. Since it becomes possible to switch to the air blowing mode, the drying operation can be started without waiting for the scheduled stop time of the humidifier 100. Since the control unit 19 sets the operation time in the air blowing mode before the scheduled stop time and the operation time in the air blowing mode after the scheduled stop time based on the time required for drying the humidifying element 17 in the air blowing mode, The drying operation time after the humidifier 100 is stopped can be suppressed as much as possible, and the appropriate humidity at the scheduled stop time can be secured.
　また、ステップＳ４２およびステップＳ５３において、送風モードでの運転可否を「停止予定時刻までの残り時間」および「検知湿度」に基づいて判断している。これは、ユーザーの快適性を大きく損ねるか否かを考慮の上で、送風モードでの運転可否を判断していると換言できる。ここで、ユーザーの快適性を損ねると判断された場合は、乾燥運転から加湿運転に切り替えることで、ユーザーの快適性を確保する制御が可能であり、一方「停止予定時刻までの残り時間」が例えば３分と短い場合には、その後加湿運転に切り替えても室内湿度の向上は期待できず非経済的と判断し、乾燥運転を継続するようにしている。すなわち、快適性と省エネ性のバランスを保つことが可能となる。 In step S42 and step S53, whether or not the operation in the air blowing mode is possible is determined based on “remaining time until scheduled stop time” and “detected humidity”. In other words, it is determined whether or not the operation in the air blowing mode is determined in consideration of whether the user's comfort is greatly impaired. Here, if it is determined that the user's comfort is impaired, it is possible to control the user's comfort by switching from the drying operation to the humidification operation, while the “time remaining until the scheduled stop time” is For example, if it is as short as 3 minutes, it is determined that it is not economical to improve indoor humidity even after switching to the humidification operation, and the drying operation is continued. That is, it becomes possible to maintain a balance between comfort and energy saving.
　図１０は、実施の形態１にかかる加湿装置１００において用いられる運転可否決定テーブルの他の例を示す図である。ステップＳ４２およびステップＳ５３において、加湿装置１００が操作手段２０や外部機器に備えられた人感センサの情報を取得可能なように構成されていれば、ユーザーの在室／不在の情報を「検知湿度」等に関連付けた図１０に示す運転可否決定テーブルに基づいて、送風モードでの運転可否を判断するようにしてもよい。室内にユーザーが不在であれば、室内の湿度を維持する必要がないため、無駄な加湿モードでの運転を抑制して、省エネルギー化を図ることができる。 FIG. 10 is a diagram illustrating another example of the operation availability determination table used in the humidifier 100 according to the first embodiment. In step S42 and step S53, if the humidifying device 100 is configured so as to be able to acquire the information of the human sensor provided in the operation means 20 or the external device, the presence / absence information of the user is indicated as “detected humidity”. ”Or the like may be determined based on the driving availability determination table shown in FIG. If there is no user in the room, there is no need to maintain the humidity in the room. Therefore, it is possible to save energy by suppressing operation in useless humidification mode.
　また、ステップＳ１１において、「乾燥タイマー」が「乾燥完了時間」未満であった場合は、ステップＳ１４からステップＳ１６により、送風モードでの動作を可能としているため、加湿装置１００の停止時刻に乾燥運転が完了しなかった場合でも、加湿装置１００の停止中に確実に加湿エレメント１７を完全に乾燥させることが可能となり、カビおよび雑菌の繁殖、ならびに臭気の発生を抑制することができる。 In step S11, when the “drying timer” is less than the “drying completion time”, the operation in the air blowing mode is enabled by steps S14 to S16, and thus the drying operation is performed at the stop time of the humidifier 100. Even when the humidification device 100 is not completed, the humidification element 17 can be surely completely dried while the humidification device 100 is stopped, and the growth of mold and bacteria and the generation of odor can be suppressed.
　また、本実施の形態１にかかる加湿装置１００では、相対湿度により各種判定を実施してもよいし、絶対湿度により各種判定を実施してもよい。 Further, in the humidifier 100 according to the first embodiment, various determinations may be performed based on relative humidity, and various determinations may be performed based on absolute humidity.
　また、本実施の形態１にかかる加湿装置１００では、図２に示した選択風量による加湿量の変動を考慮して、ステップＳ１６、ステップＳ２３およびステップ５６にて「乾燥タイマー」のカウント方法を変更し、さらに、ステップＳ３２における「装置運転時の乾燥運転時間」の算出式を変更していたが、加湿量は「乾球湿度と湿球湿度の差分」によっても変動するため、「乾球湿度と湿球湿度の差分」に応じて、「乾燥タイマー」のカウント方法、および「装置運転時の乾燥運転時間」の算出式を変更するようにしてもよい。 Further, in the humidifying apparatus 100 according to the first embodiment, the “drying timer” counting method is changed in steps S16, S23, and 56 in consideration of the variation in the humidification amount due to the selected air volume shown in FIG. Furthermore, although the calculation formula of “dry operation time during device operation” in step S32 has been changed, the humidification amount varies depending on “difference between dry bulb humidity and wet bulb humidity”. The “drying timer” counting method and the “drying operation time during device operation” calculation formula may be changed according to the “difference between the wet bulb humidity” and the “wet bulb humidity”.
　具体的には、選択風量が「強」の場合に、加湿量が１００％となる「乾球湿度と湿球湿度の差分」が「１０℃」だった場合、選択風量が「強」かつ「乾球湿度と湿球湿度の差分」が「５℃」の場合は、加湿量が５０％となるため、「乾燥タイマー」のカウントを、２秒進むごとに１秒をカウントとし、「装置運転時の乾燥運転時間」の算出式は、「装置運転時の乾燥運転時間」＝（「適正加湿量キープ時間」－「乾燥タイマー」）×２とする。 Specifically, when the selected air volume is “strong” and the “difference between dry bulb humidity and wet bulb humidity” at which the humidification amount is 100% is “10 ° C.”, the selected air volume is “strong” and “ When the “Difference between dry bulb humidity and wet bulb humidity” is “5 ° C.”, the humidification amount is 50%. Therefore, the count of the “dry timer” is counted as 1 second every 2 seconds. The calculation formula of “drying operation time” is “drying operation time during device operation” = (“appropriate humidification amount keeping time” − “drying timer”) × 2.
　選択風量が「弱」で、かつ「乾球湿度と湿球湿度の差分」が「５℃」だった場合は、「乾燥タイマー」のカウントを、４秒進むごとに１秒をカウントとし、「装置運転時の乾燥運転時間」の算出式は、「装置運転時の乾燥運転時間」＝（「適正加湿量キープ時間」－「乾燥タイマー」）×４とする。 If the selected air volume is “Weak” and the “Difference between dry bulb humidity and wet bulb humidity” is “5 ° C.”, the “dry timer” counts as 1 second every 4 seconds. The calculation formula of “dry operation time during device operation” is “dry operation time during device operation” = (“appropriate humidification amount keeping time” − “dry timer”) × 4.
　また、湿球温度については、個別にセンサを設けるようにしてもよいし、温度センサ２３の検知する乾球温度と湿度センサ２２の検知する相対湿度から算出するようにしてもよい。 Also, the wet bulb temperature may be provided separately, or may be calculated from the dry bulb temperature detected by the temperature sensor 23 and the relative humidity detected by the humidity sensor 22.
　なお、乾球温度と湿球温度を計測または算出するための各種温度センサ及び湿度センサは、加湿エレメント１７の直前に配置することが望ましい。このため、ステップＳ４２、ステップＳ４３、ステップＳ５２、およびステップＳ５３の判定で用いる「室内湿度」検知用のセンサは、乾球温度と湿球温度を計測または算出するための各種センサとは、別個に設けるようにしてもよい。 It should be noted that various temperature sensors and humidity sensors for measuring or calculating the dry bulb temperature and the wet bulb temperature are preferably arranged immediately before the humidifying element 17. For this reason, the sensor for detecting “indoor humidity” used in the determinations of step S42, step S43, step S52, and step S53 is separate from various sensors for measuring or calculating the dry bulb temperature and the wet bulb temperature. You may make it provide.
　また、本実施の形態１にかかる加湿装置１００では、「停止予定時刻」を操作手段２０に備えられたスケジュール機能における次回の運転／停止スケジュール情報により設定していたが、操作手段２０のスケジュール機能でなく、過去の運転／停止履歴情報を加湿装置１００または操作手段２０が蓄積し、次回の「停止予定時刻」を推定するようにしてもよい。 Further, in the humidifying apparatus 100 according to the first embodiment, the “scheduled stop time” is set by the next operation / stop schedule information in the schedule function provided in the operation unit 20, but the schedule function of the operation unit 20 Instead, the past operation / stop history information may be accumulated by the humidifying device 100 or the operation means 20 to estimate the next “scheduled stop time”.

FIG. 11 to FIG. 13 are flowcharts illustrating an example of a control operation performed by the control unit of the humidifier according to the second embodiment. Items that are not particularly described are the same as those in the first embodiment, and the same functions and configurations are described using the same reference numerals. In addition, description of the same functions and configurations as those of the first embodiment is omitted.
　実施の形態１との相違点は、「停止予定時刻までの残り時間」が「乾燥運転準備時間」に達した場合に、加湿モードと送風モードの判定閾値を実施の形態１における第１の規定湿度である「目標湿度＋５％」を第３の規定湿度である「目標湿度＋８％」へ変更し、第２の規定湿度である「目標湿度－５％」を第４の規定湿度である「目標湿度＋２％」へ変更することにより、「装置運転時の乾燥運転時間」に到達する前に、室内湿度をユーザーの快適性が損なわれない範囲でなるべく高い「目標湿度＋２％」から「目標湿度＋８％」に上げるように制御する点にある。 The difference from the first embodiment is that when the “remaining time until the scheduled stop time” reaches the “dry operation preparation time”, the determination threshold values of the humidification mode and the air blowing mode are set as the first regulation in the first embodiment. The “target humidity + 5%” that is the humidity is changed to the “target humidity + 8%” that is the third specified humidity, and the “target humidity−5%” that is the second specified humidity is the fourth specified humidity. By changing to “target humidity + 2%”, before reaching the “drying operation time during device operation”, the indoor humidity is changed from “target humidity + 2%” as high as possible within the range that does not impair user comfort. The control is to increase the humidity to "8%".
　以下に、上記実施の形態との相違点となるステップについて説明する。図１１に示すように、ステップＳ３２において、「装置運転時の乾燥運転時間」を設定後、ステップＳ２３１において、「乾燥運転準備時間」を以下の式で設定する。すなわち、「乾燥運転準備時間」＝「装置運転時の乾燥運転時間」＋第１の規定時間に設定する。本実施の形態２において、第１の規定時間は「６０ｍｉｎ」としておく。 Hereinafter, steps that are different from the above embodiment will be described. As shown in FIG. 11, after setting “drying operation time during apparatus operation” in step S <b> 32, in step S <b> 231, “drying operation preparation time” is set by the following equation. That is, “dry operation preparation time” = “dry operation time during device operation” + first specified time. In the second embodiment, the first specified time is set to “60 min”.
　図１２に示すように、ステップＳ４３において、湿度センサ２２の検知湿度が第１の規定湿度である「目標湿度＋５％」以上であると判断されると、ステップＳ２４１へ進む。ステップＳ２４１において、「停止予定時刻までの残り時間」がステップＳ２３１にて設定された「乾燥運転準備時間」未満であるかが判断される。「停止予定時刻までの残り時間」が「乾燥運転準備時間」未満の場合（ステップＳ２４１，Ｙｅｓ）、ステップＳ２４２へ進む。一方、「停止予定時刻までの残り時間」が「乾燥運転準備時間」以上の場合（ステップＳ２４１，Ｎｏ）、ステップＳ４４にて制御モードを送風モードへ変更の上、ステップＳ３１に戻る。 As shown in FIG. 12, when it is determined in step S43 that the humidity detected by the humidity sensor 22 is equal to or higher than “target humidity + 5%” that is the first specified humidity, the process proceeds to step S241. In step S241, it is determined whether the “remaining time until the scheduled stop time” is less than the “dry operation preparation time” set in step S231. When the “remaining time until the scheduled stop time” is less than the “dry operation preparation time” (step S241, Yes), the process proceeds to step S242. On the other hand, if the “remaining time until the scheduled stop time” is equal to or greater than the “drying operation preparation time” (No in step S241), the control mode is changed to the air blowing mode in step S44, and the process returns to step S31.
　ステップＳ２４２において、湿度センサ２２の検知湿度が第３の規定湿度である「目標湿度＋８％」以上であるかが判断される。検知湿度が「目標湿度＋８％」未満の場合は（ステップＳ２４２，Ｎｏ）、ステップＳ４５へ進む。一方、検知湿度が「目標湿度＋８％」以上の場合は（ステップＳ２４２，Ｙｅｓ）、ステップＳ４４にて制御モードを送風モードへ変更の上、ステップＳ３１へ戻る。 In step S242, it is determined whether the humidity detected by the humidity sensor 22 is equal to or higher than “target humidity + 8%”, which is the third specified humidity. If the detected humidity is less than “target humidity + 8%” (step S242, No), the process proceeds to step S45. On the other hand, when the detected humidity is “target humidity + 8%” or more (step S242, Yes), the control mode is changed to the air blowing mode in step S44, and the process returns to step S31.
　図１３に示すように、ステップＳ５１において、「停止予定時刻までの残り時間」が「装置運転時の乾燥運転時間」以上であると判断されると（ステップＳ５１，Ｎｏ）、ステップＳ２５１へ進む。 As shown in FIG. 13, if it is determined in step S51 that the “remaining time until the scheduled stop time” is equal to or greater than the “drying operation time during device operation” (step S51, No), the process proceeds to step S251.
　ステップＳ２５１において、「停止予定時刻までの残り時間」がステップＳ２３１にて設定された「乾燥運転準備時間」未満であるかが判断される。「停止予定時刻までの残り時間」が「乾燥運転準備時間」未満の場合（ステップＳ２５１，Ｙｅｓ）、ステップＳ２５２へ進む。一方、「停止予定時刻までの残り時間」が「乾燥運転準備時間」以上の場合（ステップＳ２５１，Ｎｏ）、ステップＳ５２に進む。 In step S251, it is determined whether the “remaining time until the scheduled stop time” is less than the “dry operation preparation time” set in step S231. When the “remaining time until the scheduled stop time” is less than the “dry operation preparation time” (step S251, Yes), the process proceeds to step S252. On the other hand, when the “remaining time until the scheduled stop time” is equal to or greater than the “dry operation preparation time” (No in step S251), the process proceeds to step S52.
　ステップＳ２５２において、湿度センサ２２の検知湿度が第４の規定湿度である「目標湿度＋２％」未満であるかが判断される。検知湿度が「目標湿度＋２％」以上の場合は（ステップＳ２５２，Ｎｏ）、ステップＳ５２へ進む。一方、検知湿度が「目標湿度＋２％」未満の場合は（ステップＳ２５２，Ｙｅｓ）、ステップＳ５４にて制御モードを加湿モードへ変更の上、ステップＳ３１へ戻る。 In step S252, it is determined whether the humidity detected by the humidity sensor 22 is less than “target humidity + 2%”, which is the fourth specified humidity. If the detected humidity is “target humidity + 2%” or more (step S252, No), the process proceeds to step S52. On the other hand, when the detected humidity is less than “target humidity + 2%” (step S252, Yes), the control mode is changed to the humidification mode in step S54, and the process returns to step S31.
　以上のように、本実施の形態２にかかる加湿装置１００は、ステップＳ２３１にて「乾燥運転準備時間」を設定し、「停止予定時刻までの残り時間」が「乾燥運転準備時間」に到達した場合に、加湿モードと送風モードを切り替える判定閾値を切り替える。具体的には、実施の形態１における第１の規定湿度である「目標湿度＋５％」および第２の規定湿度である「目標湿度－５％」をそれぞれ第３の規定湿度である「目標湿度＋８％」および第４の規定湿度である「目標湿度＋２％」へ変更することにより、「装置運転時の乾燥運転時間」に到達する前に、予めユーザーの快適性が損なわれない範囲でなるべく高い「目標湿度＋２％」から「目標湿度＋８％」に室内湿度を上げるよう制御しているため、「装置運転時の乾燥運転」を開始後、加湿量の低下が始まった場合でも、停止予定時刻になるまで、快適性を確保できるようになる。 As described above, the humidifying apparatus 100 according to the second embodiment sets the “dry operation preparation time” in step S231, and the “remaining time until the scheduled stop time” has reached the “dry operation preparation time”. In this case, the determination threshold value for switching between the humidifying mode and the air blowing mode is switched. Specifically, “target humidity + 5%” that is the first specified humidity and “target humidity−5%” that is the second specified humidity in Embodiment 1 are respectively set to “target humidity” that is the third specified humidity. By changing to “+ 8%” and “target humidity + 2%”, which is the fourth specified humidity, before reaching the “drying operation time during device operation”, the user's comfort should not be impaired in advance. Since the room humidity is controlled to increase from the high “target humidity + 2%” to the “target humidity + 8%”, it is scheduled to stop even if the amount of humidification starts to decrease after starting “drying operation during device operation” Until the time comes, comfort can be secured.
実施の形態３.
　図１４および図１５は、実施の形態３にかかる加湿装置の制御部による制御動作の一例を示すフローチャートである。なお、特に記述しない項目については実施の形態２と同様とし、同一の機能および構成については同一の符号を用いて述べることとする。また、実施の形態２と同一の機能および構成についての説明は省略する。 Embodiment 3.
14 and 15 are flowcharts illustrating an example of a control operation performed by the control unit of the humidifier according to the third embodiment. Items that are not particularly described are the same as those in the second embodiment, and the same functions and configurations are described using the same reference numerals. In addition, description of the same functions and configurations as those of the second embodiment is omitted.
　上記実施の形態２との相違点は、「強風量時の湿度変化率」と「弱風量時の湿度変化率」を算出し、さらに「加湿量０時の湿度変化率」を推定することで、「装置運転時の乾燥運転時間」をより長く補正可能にした点にある。以下に、上記実施の形態２との相違点となるステップについて説明する。 The difference from the second embodiment is that “humidity change rate at the time of strong air flow” and “humidity change rate at the time of weak air flow” are calculated, and further, “humidity change rate at 0 humidification amount” is estimated. The “drying operation time during operation of the apparatus” can be corrected longer. The steps that are different from the second embodiment will be described below.
　まず、図１５に示すステップＳ３６１からステップＳ３７６における「加湿量０時の湿度変化率」を推定する制御フローについて説明する。ステップＳ３６１において、「停止予定時刻までの残り時間」が、図１４に示すステップＳ２３１にて設定された「乾燥運転準備時間」以上であるかが判断される。「停止予定時刻までの残り時間」が「乾燥運転準備時間」未満の場合（ステップＳ３６１，Ｎｏ）、ステップＳ３６７へ進む。一方、「停止予定時刻までの残り時間」が「乾燥運転準備時間」以上の場合（ステップＳ３６１，Ｙｅｓ）、ステップＳ３６２にて「弱風量時の湿度変化率」をクリアし、ステップＳ３６３にて、「弱風量かつ加湿モードでの運転タイマー」をクリアし、ステップＳ３６４にて、「強風量時の湿度変化率」をクリアし、ステップＳ３６５にて「強風量かつ加湿モードでの運転タイマー」をクリアし、ステップＳ３６６にて、「加湿量０時の湿度変化率」をクリアの上、ステップＳ４１へ進む。 First, the control flow for estimating the “humidity change rate when the humidification amount is 0” in steps S361 to S376 shown in FIG. 15 will be described. In step S361, it is determined whether the “remaining time until the scheduled stop time” is equal to or greater than the “dry operation preparation time” set in step S231 shown in FIG. When the “remaining time until the scheduled stop time” is less than the “dry operation preparation time” (step S361, No), the process proceeds to step S367. On the other hand, when the “remaining time until the scheduled stop time” is equal to or greater than the “dry operation preparation time” (step S361, Yes), the “humidity change rate during weak air flow” is cleared in step S362, and in step S363, Clear “Operation timer in weak air volume and humidification mode”, clear “Humidity change rate in strong air volume” in step S364, and clear “Operation timer in high air volume and humidification mode” in step S365 In step S366, the "humidity change rate when the humidification amount is 0" is cleared, and the process proceeds to step S41.
　ステップＳ３６７において、「弱風量時の湿度変化率」が記憶されているか判断される。「弱風量時の湿度変化率」が記憶されている場合は（ステップＳ３６７，Ｙｅｓ）、ステップＳ３７１へ進む。一方、「弱風量時の湿度変化率」が記憶されていない場合は（ステップＳ３６７，Ｎｏ）、ステップＳ３６８へ進む。 In step S367, it is determined whether or not the “humidity change rate during weak air flow” is stored. When the “humidity change rate at the time of weak air flow” is stored (step S367, Yes), the process proceeds to step S371. On the other hand, when the “humidity change rate at the time of weak air flow” is not stored (step S367, No), the process proceeds to step S368.
　ステップＳ３６８において「弱風量」へ変更され、ステップＳ３６９において「弱風量かつ加湿モードでの運転タイマー」がカウントされるとともに、カウント値が規定時間（本実施の形態３においては２０分とする）以上か判断される。「弱風量かつ加湿モードでの運転タイマー」が２０分未満の場合は（ステップＳ３６９，Ｎｏ）、ステップＳ４１へ進む。一方、「弱風量かつ加湿モードでの運転タイマー」が２０分以上となった場合は（ステップＳ３６９，Ｙｅｓ）、ステップＳ３７０にて「１０分前の検知湿度」と「現在の検知湿度」との差分を「弱風量時の湿度変化率」として記憶の上、ステップＳ３７１へ進む。 In step S368, it is changed to “weak air volume”, and in step S369, “the operation timer in the weak air volume and humidification mode” is counted, and the count value is equal to or longer than a specified time (20 minutes in the third embodiment). Is judged. If the “operation timer in the weak air amount and humidification mode” is less than 20 minutes (No in step S369), the process proceeds to step S41. On the other hand, when the “operation timer in the weak air amount and humidification mode” becomes 20 minutes or more (step S369, Yes), in step S370, “detected humidity before 10 minutes” and “current detected humidity” The difference is stored as “humidity change rate during weak air flow”, and the process proceeds to step S371.
　ここで、「湿度変化率」の算出時に規定時間である「２０分前の検知湿度」ではなく「１０分前の検知湿度」を参照したのは、ステップＳ３６８にて風量が「強」から「弱」へ変更があった場合の湿度変化率が安定するまでの時間を考慮するためである。 Here, instead of “the detected humidity before 20 minutes” which is the prescribed time when calculating the “humidity change rate”, the “detected humidity before 10 minutes” was referred to in step S368 from “strong” to “ This is to take into account the time until the rate of change in humidity when the change is made to “weak”.
　ステップＳ３７１において「強風量時の湿度変化率」が記憶されているか判断される。「強風量時の湿度変化率」が記憶されている場合は（ステップＳ３７１，Ｙｅｓ）、ステップＳ４１へ進む。一方、「強風量時の湿度変化率」が記憶されていない場合は（ステップＳ３７１，Ｎｏ）、ステップＳ３７２へ進む。 In step S371, it is determined whether or not the “humidity change rate during strong air flow” is stored. If the “humidity change rate at the time of strong air flow” is stored (step S371, Yes), the process proceeds to step S41. On the other hand, when the “humidity change rate at the time of strong air flow” is not stored (step S371, No), the process proceeds to step S372.
　ステップＳ３７２において「強風量」へ変更され、ステップＳ３７３において、「強風量かつ加湿モードでの運転タイマー」がカウントされるとともに、カウント値が規定時間（本実施の形態３においては２０分とする）以上か判断される。「強風量かつ加湿モードでの運転タイマー」が２０分未満の場合は（ステップＳ３７３，Ｎｏ）、ステップＳ４１へ進む。一方、「強風量かつ加湿モードでの運転タイマー」が２０分以上となった場合は（ステップＳ３７３，Ｙｅｓ）、ステップＳ３７４にて「１０分前の検知湿度」と「現在の検知湿度」との差分を「強風量時の湿度変化率」として記憶の上、ステップＳ３７５に進む。 In step S372, it is changed to “strong air volume”. In step S373, “the operation timer in the strong air volume and humidification mode” is counted, and the count value is a specified time (20 minutes in the third embodiment). It is judged whether it is above. When the “operation timer in the strong air volume and humidification mode” is less than 20 minutes (step S373, No), the process proceeds to step S41. On the other hand, when the “operation timer in the strong air volume and humidification mode” is 20 minutes or more (step S373, Yes), in step S374, “detected humidity before 10 minutes” and “current detected humidity” The difference is stored as “humidity change rate during strong air flow”, and the process proceeds to step S375.
　ステップＳ３７５において、「加湿量０時の湿度変化率」を以下の式で推定して記憶する。「加湿量０時の湿度変化率」＝「弱風量時の湿度変化率」－（「強風量時の湿度変化率」－「弱風量時の湿度変化率」）とする。 In step S375, the “humidity change rate when the humidification amount is 0” is estimated by the following equation and stored. “Humidity change rate at 0 humidification amount” = “Humidity change rate at weak air flow” − (“Humidity change rate at high air flow” − “Humidity change rate at low air flow”).
　具体的には、「強風量時の湿度変化率」が、「１０分で＋０．５％」、「弱風量時の湿度変化率」が、「１０分で－０．５％」の場合、「加湿量０時の湿度変化率」は「１０分で－１．５％」とする。また、「強風量時の湿度変化率」が、「１０分で＋２．０％」、「弱風量時の湿度変化率」が、「１０分で＋０．５％」の場合、「加湿量０時の湿度変化率」は「１０分で－１．０％」とする。 Specifically, when the “humidity change rate during strong air flow” is “+ 0.5% in 10 minutes” and the “humidity change rate during weak air flow” is “−0.5% in 10 minutes”, The “humidity change rate when the humidification amount is 0” is “−1.5% in 10 minutes”. Further, when the “humidity change rate at the time of strong air flow” is “+ 2.0% in 10 minutes” and the “humidity change rate at the time of light air flow” is “+ 0.5% at 10 minutes”, the “humidification amount 0” The “humidity change rate” is “−1.0% in 10 minutes”.
　なお、湿度変化率は、加湿装置１００からの加湿量の他に、換気により加湿対象空間へ流入する室外空気の温湿度や給気量、換気により加湿対象空間から排出される室内空気の排気量、全熱交換器を有する換気装置においては、全熱交換器により回収される湿度分等、様々な要因により変動するが、加湿装置１００以外の上記要因に大きな変化がなければ、本発明の実施の形態のように少なくとも２つの加湿量にて、加湿装置を運転することで、「加湿量０時の湿度変化率」の推定が可能となる。 In addition to the humidification amount from the humidifier 100, the humidity change rate is the temperature and humidity of the outdoor air that flows into the humidification target space due to ventilation, the air supply amount, and the exhaust amount of indoor air that is exhausted from the humidification target space due to ventilation In a ventilator having a total heat exchanger, it fluctuates due to various factors such as the humidity recovered by the total heat exchanger, but if there is no significant change in the above factors other than the humidifier 100, the present invention is carried out. By operating the humidifier with at least two humidification amounts as in the above embodiment, it is possible to estimate the “humidity change rate when the humidification amount is 0”.
　ステップ３７５にて「加湿量０時の湿度変化率」を記憶した後に、ステップＳ３７６において、ユーザーの設定した「選択風量」へ設定される。 After storing the “humidity change rate when the humidification amount is 0” in step 375, in step S376, the “selected air volume” set by the user is set.
　図１４に示すステップＳ３３１では、「加湿量０時の湿度変化率」が記憶されているか判断される。「加湿量０時の湿度変化率」が記憶されている場合は（ステップＳ３３１，Ｙｅｓ）、ステップＳ３３２へ進む。一方、「加湿量０時の湿度変化率」が記憶されていない場合は（ステップＳ３３１，Ｎｏ）、ステップＳ３２へ進み、その後、ステップＳ３３５にて「装置運転時の乾燥運転時間」を「補正未完」に設定の上、ステップＳ２３１に進む。 In step S331 shown in FIG. 14, it is determined whether “humidity change rate when humidification amount is 0” is stored. When the “humidity change rate when the humidification amount is 0” is stored (step S331, Yes), the process proceeds to step S332. On the other hand, when the “humidity change rate when the humidification amount is 0” is not stored (No in step S331), the process proceeds to step S32, and then in step S335, “drying operation time during apparatus operation” is set to “incomplete correction”. ”And the process proceeds to step S231.
　ステップＳ３３２において「装置運転時の乾燥運転時間」の補正が完了しているか判断される。補正が完了している場合は（ステップＳ３３２，Ｙｅｓ）、ステップＳ２３１へ進む。一方、補正が完了していない場合は（ステップＳ３３２，Ｎｏ）、ステップＳ３３３へ進む。 In step S332, it is determined whether or not the correction of “drying operation time during apparatus operation” has been completed. If the correction has been completed (step S332, Yes), the process proceeds to step S231. On the other hand, when the correction is not completed (step S332, No), the process proceeds to step S333.
　ステップＳ３３３において、「装置運転時の乾燥運転時間」を以下の通り補正する。まず、図２における「加湿量一定期間終了時」の湿度を「強風量時の湿度変化率」および「弱風量時の湿度変化率」を用いて、推定する。 In step S333, the “drying operation time during device operation” is corrected as follows. First, the humidity at the “end of the constant humidification amount period” in FIG. 2 is estimated using the “humidity change rate at the time of strong air flow” and “humidity change rate at the time of weak air flow”.
　なお、「加湿量一定期間終了時」とは、具体的には、図２（ａ），（ｂ）における「２．０ｈｒ」時であり、図２（ｃ），（ｄ）における「４．０ｈｒ」時である。 Note that “at the end of the constant humidification amount period” specifically means “2.0 hr” in FIGS. 2A and 2B, and “4. in FIG. 2C and FIG. 2D”. 0 hr ".
　選択風量が「強」の場合、「強風量時の計算結果」＝現在湿度＋（「装置運転時の乾燥運転時間」－現在時刻）×「強風量時の湿度変化率」と、第４の規定湿度である「目標湿度＋２％」との大小関係が比較され、「強風量時の計算結果」が「目標湿度＋２％」以上であれば、「加湿量一定期間終了時の推定湿度」＝「目標湿度＋２％」とし、「強風量時の計算結果」が「目標湿度＋２％」未満であれば、「加湿量一定期間終了時の推定湿度」＝「強風量時の計算結果」とする。 When the selected air volume is “strong”, “calculation result at the time of strong air volume” = current humidity + (“drying operation time during device operation” −current time) × “humidity change rate at high air volume” If the magnitude relationship with the target humidity “target humidity + 2%” is compared, and the “calculation result at high air flow” is equal to or greater than “target humidity + 2%”, “estimated humidity at the end of a certain period of humidification” = If “target humidity + 2%” and “calculation result at high air flow” is less than “target humidity + 2%”, “estimated humidity at the end of a certain period of humidification” = “calculation result at high air flow” .
　また、選択風量が「弱」の場合、「弱風量時の計算結果」＝現在湿度＋（「装置運転時の乾燥運転時間」－現在時刻）×「弱風量時の湿度変化率」と、第４の規定湿度である「目標湿度＋２％」との大小関係が比較され、「弱風量時の計算結果」が「目標湿度＋２％」以上であれば、「加湿量一定期間終了時の推定湿度」＝「目標湿度＋２％」とし、「弱風量時の計算結果」が「目標湿度＋２％」未満であれば、「加湿量一定期間終了時の推定湿度」＝「弱風量時の計算結果」とする。 In addition, when the selected air volume is “weak”, “calculation result at the time of weak air flow” = current humidity + (“drying operation time during operation of the device” −current time) × “humidity change rate at low air flow” 4 is compared with the “target humidity + 2%”, which is the specified humidity of No. 4, and if the “calculation result at the time of low air flow” is not less than “target humidity + 2%”, the “estimated humidity at the end of a certain period of humidification” ”=“ Target humidity + 2% ”, and“ calculation result at low air flow ”is less than“ target humidity + 2% ”,“ estimated humidity at the end of a certain period of humidification ”=“ calculation result at low air flow ” And
　次に、図２における「加湿量が減少する期間」において、検知湿度が第２の規定湿度である「目標湿度－５％」以上となる「補正時間」を算出する。なお、「加湿量が減少する期間」とは、具体的には、図２（ａ），（ｂ）における「２．０ｈｒ」から「３．０ｈｒ」の期間であり、図２（ｃ），（ｄ）における「４．０ｈｒ」から「６．０ｈｒ」の期間である。 Next, in the “period in which the humidification amount decreases” in FIG. 2, a “correction time” in which the detected humidity is equal to or higher than “target humidity—5%” that is the second specified humidity is calculated. Note that the “period in which the humidification amount decreases” is specifically a period from “2.0 hr” to “3.0 hr” in FIGS. 2A and 2B, and FIG. This is the period from “4.0 hr” to “6.0 hr” in (d).
　なお、「加湿量一定期間終了時の推定湿度」が、第２の規定湿度である「目標湿度－５％」未満の場合、「装置運転時の乾燥運転時間」の補正は実施しない。この処理は、適正湿度（ここでは第２の規定湿度である「目標湿度－５％」）を確保できない環境下で、「装置運転時の乾燥運転時間」を延長する補正を実施することで、室内湿度がさらに悪化することを回避しているとも換言できる。 Note that if the “estimated humidity at the end of a certain period of humidification” is less than the second specified humidity, “target humidity—5%”, the “drying operation time during device operation” is not corrected. This process is performed by performing a correction to extend the “drying operation time during device operation” in an environment where appropriate humidity (here, “target humidity—5%”, which is the second specified humidity) cannot be secured, In other words, the indoor humidity is prevented from further worsening.
　また、「加湿量一定期間終了時の推定湿度」が、第２の規定湿度である「目標湿度－５％」以上かつ「加湿量０時の湿度変化率」が０以上の場合は、乾燥タイマーが「乾燥完了時間」となるまでの残り時間を、新しい「装置運転時の乾燥運転時間」として更新し、ステップＳ３３４にて「装置運転時の乾燥運転時間」を「補正完了」に設定の上、ステップＳ２３１に進む。この処理は、加湿量０時においても湿度が上昇する環境下においては、加湿量０となっても適正湿度（ここでは第２の規定湿度である「目標湿度－５％」）を確保できるため、加湿装置１００の停止後の乾燥運転を省略し、消費電力を抑制可能にしているとも換言できる。 If the “estimated humidity at the end of a certain period of humidification” is equal to or higher than the “second target humidity” of “target humidity—5%” and the “humidity change rate when the humidification amount is 0” is 0 or more, the drying timer Is updated as the new “drying operation time during device operation”, and “drying operation time during device operation” is set to “correction completed” in step S334. The process proceeds to step S231. In this environment, even in the environment where the humidity increases even when the humidification amount is 0, an appropriate humidity (here, “target humidity—5%” which is the second specified humidity) can be ensured even when the humidification amount is 0. In other words, the drying operation after the humidifier 100 is stopped is omitted, and the power consumption can be suppressed.
　また、「加湿量一定期間終了時の推定湿度」が、第２の規定湿度である「目標湿度－５％」以上かつ「加湿量０時の湿度変化率」が０未満の場合は、「補正時間」＝（「目標湿度－５％」－「加湿量一定期間終了時の推定湿度」）÷「加湿量０時の湿度変化率」を算出し、「装置運転時の乾燥運転時間」＋「補正時間」を新しい「装置運転時の乾燥運転時間」として更新し、ステップＳ３３４にて「装置運転時の乾燥運転時間」を「補正完了」に設定の上、ステップＳ２３１に進む。なお、「装置運転時の乾燥運転時間」を更新する場合、乾燥タイマーが「乾燥完了時間」となるまでの残り時間を上限とするよう更新値を設定する。 In addition, if the “estimated humidity at the end of a certain period of humidification” is equal to or higher than the second target humidity “target humidity −5%” and the “humidity change rate at 0 humidification” is less than 0, "Time" = ("Target humidity-5%"-"Estimated humidity at the end of a certain period of humidification") / "Humidity change rate when the humidification amount is 0" is calculated, and "Dry operation time during device operation" + " The “correction time” is updated as a new “drying operation time during device operation”, the “drying operation time during device operation” is set to “correction completion” in step S334, and the process proceeds to step S231. When the “drying operation time during device operation” is updated, the update value is set so that the remaining time until the drying timer reaches the “drying completion time” is set as an upper limit.
　ステップＳ３３において、送風モードと判定された場合、ステップＳ３３６において、「弱風量かつ加湿モードでの運転タイマー」をクリアし、ステップＳ３３７において、「強風量かつ加湿モードでの運転タイマー」をクリアの上、ステップＳ５１に進む。一方、ステップＳ３３において、加湿モードと判定された場合、ステップＳ３６１へ進む。 If it is determined in step S33 that the air blowing mode is selected, in step S336, the “operation timer in the weak air amount and humidification mode” is cleared, and in step S337, the “operation timer in the strong air amount and humidification mode” is cleared. The process proceeds to step S51. On the other hand, when it determines with humidification mode in step S33, it progresses to step S361.
　以上のように、本実施の形態３にかかる加湿装置１００は、ステップＳ３７０において「弱風量時の湿度変化率」を算出し、ステップＳ３７４において「強風量時の湿度変化率」を算出することで、ステップＳ３７５において「加湿量０時の湿度変化率」を推定したため、ステップＳ３３３において、加湿エレメント１７の乾燥が進むにつれて、加湿量の低下が始まる期間においても、室内を適正湿度（本実施の形態３では、第２の規定湿度である「目標湿度－５％」とした）を保てる時間を推定することが可能となり、「装置運転時の乾燥運転時間」をより長く設定できるようになったため、「装置停止時の乾燥運転時間」がより短くなり、消費電力の低減に貢献できる。この制御は、推定された湿度変化率に基づいて、停止予定時刻前の送風モードでの運転時間を延長し、停止予定時刻後の送風モードでの運転時間を短縮する制御であるとも換言できる。これにより、雨の日等では「装置停止時の乾燥運転時間」を０にすることも可能となる。 As described above, the humidifying apparatus 100 according to the third embodiment calculates the “humidity change rate at the time of weak air flow” in step S370 and calculates the “humidity change rate at the time of strong air flow” in step S374. Since the “humidity change rate when the humidification amount is 0” is estimated in step S375, in step S333, as the humidification element 17 progresses in drying, the room is kept at the proper humidity (this embodiment) even during the period when the humidification amount starts to decrease. 3), it is possible to estimate the time during which the second specified humidity “target humidity—5%” can be maintained, and the “drying operation time during device operation” can be set longer. The “drying operation time when the device is stopped” is shortened, which contributes to reduction of power consumption. In other words, this control is a control for extending the operation time in the blowing mode before the scheduled stop time and shortening the operation time in the blowing mode after the scheduled stop time based on the estimated humidity change rate. Thereby, it becomes possible to set the “drying operation time when the apparatus is stopped” to 0 on a rainy day or the like.
