Note that the counting of the “drying timer” in step S23 is changed according to the selected air volume as in step S16.
- step S25 it is determined whether or not a fixed time of 5 minutes has elapsed since the air blowing mode was entered.
- 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.
- 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.
- step S26 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.
- step S26 “drying operation time during apparatus operation” is initialized to “0”, and the process proceeds to step S31 shown in FIG.
- 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.
- 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. .
- step S31 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.
- 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%.
- step S46 the “drying timer” has been cleared in step S46, which will be described later, that is, the count is stopped at 0.
- operation time “appropriate humidification amount keeping time” is set.
- 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.
- 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.
- 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.
- the process proceeds to Step S43.
- step S44 the control mode is switched to the blow mode, and the process returns to step S31.
- FIG. 9 is a diagram illustrating an operation availability determination table used in the humidifier 100 according to the first embodiment.
- “remaining time until scheduled stop time”, “detected humidity”, and availability of operation in the air blowing mode are related.
- 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.
- target humidity ⁇ 5% the second specified humidity used to determine whether to switch from the air blowing mode to the humidifying mode.
- 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.
- step S42 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.
- 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.
- the humidifying device 100 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.
- 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.
- 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.
- 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.
- mold and germs are caused by the residual water remaining in the machine. It is hard to generate the trouble that breeds.
- the chalk component is not concentrated.
- step S46 the “drying timer” is cleared, that is, the count is stopped when 0, and the process proceeds to step S47.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- step S55 the water supply valve 9 is closed while the sirocco fan 4 is rotating, and the process proceeds to step S56.
- 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.
- 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.
- the humidification apparatus 100 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.
- step S56 the “drying timer” starts counting, and the process proceeds to step S57.
- “drying timer” will start the count from 0.
- 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.
- 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.
- the humidifying device 100 sets the “appropriate humidification amount keeping time” based on the characteristics of the humidifying element 17 shown in FIG.
- 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.
- 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.
- 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.
- 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.
- FIG. 10 is a diagram illustrating another example of the operation availability determination table used in the humidifier 100 according to the first embodiment.
- 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.
- 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.

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”.
実施の形態2.
図11から図13は、実施の形態2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1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1と同一の機能および構成についての説明は省略する。Embodiment 2.
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.

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.

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.

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.
なお、図16は、実施の形態1における制御装置25のハードウェア構成を示す図である。制御装置25は、例えばCPU(Central Processing Unit)31とメモリ32が搭載されたマイクロコンピュータ33によって実現される。マイクロコンピュータ33では、プログラムを実行することでCPU(Central Processing Unit)31が制御部19として機能する。また、ROM(Read Only Memory)やRAM(Random Access Memory)等のメモリ32が記憶部16として機能する。CPU31が実行するプログラムは、記憶部16に記憶されていてもよいし、他の記憶媒体に記憶されていてもよい。
FIG. 16 is a diagram illustrating a hardware configuration of the control device 25 according to the first embodiment. The control device 25 is realized by, for example, a microcomputer 33 on which a CPU (Central Processing Unit) 31 and a memory 32 are mounted.
