Specifically, the heating means 19 corresponds to, for example, a heater.
制御手段18は、浴室外部空間と浴室内部空間の空気の流れをコントロールし、さらに加熱手段19による加熱を調整するが、詳細は後述する。   The control means 18 controls the flow of air between the bathroom exterior space and the bathroom interior space, and further adjusts the heating by the heating means 19, which will be described in detail later.
続いて、図3を用いて、制御手段18の動作の流れについて説明する。図3は、制御手段の構成を示すブロック図である。   Next, the operation flow of the control means 18 will be described with reference to FIG. FIG. 3 is a block diagram showing the configuration of the control means.
制御手段18は、内部にCPU(Central Processing Unit)、RAM(Random Access Memory)、ROM(Read Only Memory)、及び浴室換気乾燥機1におけるステッピングモータやダンパー等の各駆動部に対応するドライバが内部バスを介して接続されている。CPUは、例えばRAMを作業領域として利用し、ROMに記憶されているプログラムを実行し、当該実行結果に基づいてドライバとデータや命令を授受することにより各駆動部の動作を制御する。制御手段18は、プログラムとして、浴室外側絶対湿度算出手段22と絶対湿度比較手段23と吸込風量変更ステッピングモータ制御手段25(以後、吸込風量変更STM制御手段)と吹出風量変更ステッピングモータ制御手段28(以後、吹出風量変更STM制御手段)と吸気ファン制御手段30と循環ファン制御手段31とを備える。   The control means 18 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and drivers corresponding to each drive unit such as a stepping motor and a damper in the bathroom ventilation dryer 1 inside. Connected via bus. For example, the CPU uses a RAM as a work area, executes a program stored in the ROM, and controls the operation of each drive unit by exchanging data and commands with the driver based on the execution result. The control means 18 includes a bathroom outside absolute humidity calculation means 22, an absolute humidity comparison means 23, a suction air amount change stepping motor control means 25 (hereinafter referred to as a suction air amount change STM control means), and a blown air amount change stepping motor control means 28 (as programs). Thereafter, a blowout air volume changing STM control means), an intake fan control means 30 and a circulation fan control means 31 are provided.
浴室外側絶対湿度算出手段22は、浴室外側湿度検知手段13と浴室外側温度検知手段14で検知した湿度及び温度から以下の算出式に基づいてそれぞれの空間毎に絶対湿度を算出する。なお、飽和水蒸気量は温度によって決められている値である。
絶対湿度(g/m3)= 飽和水蒸気量(g/m3)×湿度(%)×100・・・(式1)
絶対湿度比較手段23は、浴室外側絶対湿度算出手段22によって算出された絶対湿度に基づいて、複数の浴室外部空間それぞれの絶対湿度を比較し、最も絶対湿度が小さい浴室外部空間を求める。
The bathroom outside absolute humidity calculating means 22 calculates the absolute humidity for each space based on the following calculation formula from the humidity and temperature detected by the bathroom outside humidity detecting means 13 and the bathroom outside temperature detecting means 14. The saturated water vapor amount is a value determined by temperature.
Absolute humidity (g / m 3 ) = saturated water vapor amount (g / m 3 ) × humidity (%) × 100 (Equation 1)
The absolute humidity comparison unit 23 compares the absolute humidity of each of the plurality of bathroom exterior spaces based on the absolute humidity calculated by the bathroom outside absolute humidity calculation unit 22 to obtain the bathroom exterior space having the smallest absolute humidity.
吸込風量変更手段24は、吸込風量変更STM制御手段25と吸込風量変更STM26と吸込風量変更ダンパー16とを備える。吸込風量変更手段24は、絶対湿度比較手段23の比較結果に基づき、複数の浴室外部空間から浴室換気乾燥機1に吸込む空気の風量の割合を変更する手段である。ここで風量の割合は、0対100あるいは100対0を含む。   The suction air volume changing means 24 includes a suction air volume changing STM control means 25, a suction air volume changing STM 26, and a suction air volume changing damper 16. The suction air volume changing means 24 is a means for changing the ratio of the air volume of air sucked into the bathroom ventilation dryer 1 from a plurality of bathroom exterior spaces based on the comparison result of the absolute humidity comparison means 23. Here, the ratio of the air volume includes 0 to 100 or 100 to 0.
風量変更STM制御手段25は、吸込風量変更STM26に対して信号を送信することで吸込風量変更ダンパー16を開閉させる。ここでは、絶対湿度比較手段23によって求められた、最も絶対湿度が小さい空気を吸込む浴室外側吸込口を開き、その他の浴室外部空間からの空気を吸込む浴室外側吸込口を閉じるように吸込風量変更STM26の制御を行う。   The air volume change STM control means 25 opens and closes the intake air volume change damper 16 by transmitting a signal to the intake air volume change STM 26. Here, the suction air volume change STM26 is determined so as to open the bathroom outside suction port for sucking air having the lowest absolute humidity and close the bathroom outside suction port for sucking air from other bathroom exterior spaces, which is obtained by the absolute humidity comparison means 23. Control.
吹出風量変更手段27は、吹出風量変更STM制御手段28と吹出風量変更STM29と吹出風量変更ダンパー17とを備える。吹出風量変更手段27は、浴室外部空間へ吹出す排気風量と浴室外側吹出口8から浴室内側に吹出す循環風量との割合を変更する。   The blown air volume changing unit 27 includes a blown air volume changing STM control unit 28, a blown air volume changing STM 29, and a blown air volume changing damper 17. The blowing air volume changing means 27 changes the ratio of the exhaust air volume that blows out to the bathroom exterior space and the circulating air volume that blows out from the bathroom outside air outlet 8 to the inside of the bathroom.
吹出風量変更STM制御手段28は、吹出風量変更STM29に対して信号を送信することで吹出風量変更ダンパー17を動作させる。また、吹出風量変更STM制御手段28は、加熱手段19を利用した乾燥処理を停止した後、浴室内側吸込口5から吸込んだ空気に対して、循環風路よりも排気風路に送風する空気を大きくするように、吹出風量変更STM29を制御する。   The blown air amount change STM control means 28 operates the blown air amount change damper 17 by transmitting a signal to the blown air amount change STM 29. Further, the blown air volume changing STM control means 28 stops the drying process using the heating means 19 and then sends the air blown to the exhaust air path rather than the circulation air path with respect to the air sucked from the bathroom inner suction port 5. The blowing air volume change STM29 is controlled so as to increase.
なお、吹出風量変更STM制御手段28は加熱手段19を利用した乾燥処理を停止後に行うのみではなく、加熱手段19を利用した乾燥処理を行う最中も、排気風路と循環風路に分配する割合を任意に変更しても良い。   The blown air amount changing STM control means 28 distributes the exhaust air flow path and the circulation air path not only after the drying process using the heating means 19 is stopped but also during the drying process using the heating means 19. The ratio may be arbitrarily changed.
吸気ファン制御手段30は、吸気ファン20の動作を制御する手段であり、例えば本体操作リモコン15からの信号に基づいて、浴室外部空間から吸込む風量の大きさを変更するために、吸気ファン20の回転数を変更する。   The intake fan control means 30 is a means for controlling the operation of the intake fan 20. For example, in order to change the amount of air sucked from the bathroom exterior space based on a signal from the main body operation remote controller 15, Change the rotation speed.
循環ファン変更手段31は、循環ファン21の動作を制御する手段であり、浴室内部空間へ送風する風量の大きさ、例えば強運転または弱運転を切り替えるために、循環ファン21の回転数を変更する。   The circulation fan changing means 31 is a means for controlling the operation of the circulation fan 21 and changes the rotation speed of the circulation fan 21 in order to switch the magnitude of the amount of air blown into the bathroom interior space, for example, strong operation or weak operation. .
次に、図4を用いて本発明に係る浴室換気乾燥機の運転動作について説明する。なお図4は、浴室換気乾燥機の動作を示すフローチャートである。ここで図4における「S」はステップを意味する。   Next, the operation of the bathroom ventilation dryer according to the present invention will be described with reference to FIG. FIG. 4 is a flowchart showing the operation of the bathroom ventilation dryer. Here, “S” in FIG. 4 means a step.
まず使用者が、例えば本体操作リモコン15を介して浴室換気乾燥機1に、運転開始の信号を送信する。   First, the user transmits an operation start signal to the bathroom ventilation dryer 1 via, for example, the main body operation remote controller 15.
運転開始の信号を受信した制御手段18は、複数ある運転種別の中から乾燥運転であるか否かを判定する(図4:S01)。   The control means 18 that has received the operation start signal determines whether or not it is a dry operation from among a plurality of operation types (FIG. 4: S01).
ここで乾燥運転とは、浴室内部及び/または浴室内部に吊るされた衣類を乾燥させるための運転である。乾燥運転の他には、例えば入浴時の寒さ防止のための暖房運転や、入浴時の暑さを和らげる涼風運転などがある。   Here, the drying operation is an operation for drying clothes in the bathroom and / or the interior of the bathroom. In addition to the drying operation, there are, for example, a heating operation for preventing cold during bathing, and a cool air operation for reducing the heat during bathing.
乾燥運転ではない場合には、制御手段18は、例えば上述の暖房運転や涼風運転などを実施するが説明は省略する(図4:S01No)。   When it is not a dry operation, the control means 18 implements, for example, the above-described heating operation or cool air operation, but the description is omitted (FIG. 4: S01 No).
乾燥運転である場合には、制御手段18は、吸気を開始する(図4:S01Yes→S02)。ここで吸気とは、浴室外部空間の空気を浴室内部空間に吸込むために浴室外側吸込口6を開き、吸気ファン20の動作を開始することである。なお、この動作では複数の浴室外部空間から吸込む全ての浴室外側吸込口6を開く。   In the case of the dry operation, the control means 18 starts intake (FIG. 4: S01 Yes → S02). Here, the intake refers to opening the bathroom outside suction port 6 and starting the operation of the intake fan 20 in order to suck air in the bathroom exterior space into the bathroom interior space. In this operation, all the bathroom outside suction ports 6 for suction from a plurality of bathroom exterior spaces are opened.
制御手段18が吸気を開始すると、浴室外側湿度検知手段13と浴室外側温度検知手段14は、浴室外部空間の湿度及び温度を検知する(図4:S03)。この処理により、複数の浴室外部空間それぞれから吸込まれた空気の湿度及び温度を検知することができる。   When the control means 18 starts intake, the bathroom outside humidity detection means 13 and the bathroom outside temperature detection means 14 detect the humidity and temperature of the bathroom exterior space (FIG. 4: S03). By this process, it is possible to detect the humidity and temperature of the air sucked from each of the plurality of bathroom exterior spaces.
続いて、浴室外側絶対湿度算出手段22は、検知した湿度及び温度に基づいて絶対湿度を算出する(図4:S04)。浴室外側絶対湿度算出手段22は、吸込む外部空間の空気それぞれについて絶対湿度の算出を行う。   Subsequently, the bathroom outside absolute humidity calculating means 22 calculates the absolute humidity based on the detected humidity and temperature (FIG. 4: S04). The bathroom outside absolute humidity calculating means 22 calculates the absolute humidity for each air in the external space to be sucked.
絶対湿度比較手段23は、それぞれの外部空間の空気について算出された絶対湿度を比較し、最も絶対湿度が小さい外部空間の空気を決定する(図4:S05)。この後のステップにおいては最も絶対湿度が小さい外部空間の空気を乾燥運転に利用する。   The absolute humidity comparison means 23 compares the absolute humidity calculated for the air in each external space, and determines the air in the external space with the lowest absolute humidity (FIG. 4: S05). In the subsequent steps, the air in the external space having the lowest absolute humidity is used for the drying operation.
吸込風量変更STM制御手段25は、最も絶対湿度が小さい外部空間の空気を浴室内部空間に取り入れるために、最も絶対湿度が小さい外部空間を吸込む浴室外側吸込口を開き、それ以外の浴室外側吸込口を閉じる(図4:S06)。つまり吸込風量STM26を介して吸込風量変更ダンパー16を動作することで、外部から浴室換気乾燥機1内に吸込む風量の割合を変更する。ここでは、風量の割合は0対100とする。   The intake air volume changing STM control means 25 opens the bathroom outside inlet for sucking the outside space with the lowest absolute humidity and takes the air in the outside space with the lowest absolute humidity into the bathroom inside space. Is closed (FIG. 4: S06). That is, by operating the suction air volume change damper 16 via the suction air volume STM26, the ratio of the air volume sucked into the bathroom ventilation dryer 1 from the outside is changed. Here, the ratio of the air volume is 0: 100.
その後、制御手段18は、最も絶対湿度が小さい空気を利用して乾燥運転を継続することで、効率よく乾燥させることが可能となる。この際、加熱手段19の運転も行うことで、乾燥時間を短縮し、さらに効率よく乾燥することができる。   Thereafter, the control means 18 can dry efficiently by continuing the drying operation using the air having the lowest absolute humidity. At this time, the heating means 19 is also operated, so that the drying time can be shortened and the drying can be performed more efficiently.
加熱手段19を用いて乾燥運転していた場合には、制御手段18は、あらかじめ決められた時間、乾燥運転を行った後、加熱手段19を使用した乾燥を終了する(図4:S07)。ただし、乾燥運転後の浴室内部空間の絶対湿度は乾燥運転前の絶対湿度に比べて上昇している。加熱手段19の停止後、浴室内部空間の温度が低下することによって、飽和水蒸気量が小さくなるため、浴室内部空間の湿度が浴室外部空間の湿度より上昇するという問題がある。つまり加熱処理終了後、一度乾いた浴室内部及び/または衣類が再度湿気を帯びるということになる。この問題を解決するために次の工程を有する。   When the drying operation is performed using the heating unit 19, the control unit 18 performs the drying operation for a predetermined time, and then ends the drying using the heating unit 19 (FIG. 4: S07). However, the absolute humidity of the bathroom interior space after the drying operation is higher than the absolute humidity before the drying operation. After the heating means 19 is stopped, the amount of saturated water vapor is reduced by the temperature of the bathroom interior space being lowered, so that the humidity of the bathroom interior space is higher than the humidity of the bathroom exterior space. In other words, after the heat treatment is finished, the interior of the bathroom once dry and / or the clothes become damp again. In order to solve this problem, the following steps are included.
吹出風量変更STM制御手段28は、浴室内側吸込口5から吸込んだ空気の誘導先を、循環風路より排気風路の方が大きくなるように、吹出風量変更ダンパー17を動作する(図4:S08)。なお、加熱手段19が停止しているので熱量ロスが発生しないため、浴室内側吸込口5から吸込んだ空気を全て排気風路に送風するように吹出風量変更ダンパーを動作させても良い。   The blown air volume change STM control means 28 operates the blown air volume change damper 17 so that the exhaust air path is larger than the circulation air path for the destination of the air sucked from the bathroom inner suction port 5 (FIG. 4 :). S08). Since the heating means 19 is stopped and no heat loss is generated, the blowout air amount changing damper may be operated so that all the air sucked from the bathroom inner suction port 5 is blown to the exhaust air passage.
この状態で制御手段18は、一定時間経過した後に運転を停止(図4:S09)し、乾燥運転を終了する。   In this state, the control means 18 stops the operation after a predetermined time has elapsed (FIG. 4: S09), and ends the drying operation.
これにより浴室内部空間が換気され、浴室内部空間の湿度が浴室外部空間の湿度と同等の値になるため、乾燥対象物の含有水分量をさらに減少させることができる。   As a result, the bathroom interior space is ventilated, and the humidity of the bathroom interior space becomes the same value as the humidity of the bathroom exterior space, so that the moisture content of the dry object can be further reduced.
以上のように、さまざまな浴室外部空間の空気環境の浴室外側絶対湿度を比較できるため、乾燥に最適な浴室外部空間の空気を浴室内部空間に吸込むことができるので、効率よく乾燥を行うことができる。   As described above, the absolute humidity outside the bathroom can be compared in the air environment of various bathroom exterior spaces, so that the air in the bathroom exterior space that is optimal for drying can be sucked into the bathroom interior space, allowing efficient drying. it can.
また、乾燥に最適な浴室外部空間の空気を浴室内部空間に吸込む風量の割合を大きくすることで、効率よく乾燥を行うことができるという効果をさらに高めることができる。   Moreover, the effect that it can dry efficiently can be further heightened by enlarging the ratio of the air volume which sucks the air of the bathroom exterior space optimal for drying into the bathroom interior space.
また、加熱手段を停止後、浴室内側吸込口から浴室外部空間に吹出す風量を浴室内部空間に吹出す風量よりも大きくすることで、乾燥対象物の含有水分量をさらに減少させることができる。
また、屋外からの吸気を行うことで、さまざまな空気環境にある浴室外部空間の空気の絶対湿度を比較できるため、効率よく乾燥を行うことができるという効果をさらに高めることができる。
(変形例)
上記実施の形態においては、浴室外側湿度検知手段13と浴室外側温度検知手段14は、浴室換気乾燥機1の本体内部に設置した。この場合、吸込風量を変更した後(図4:S08)天候変化等が原因で浴室外部空間の空気の絶対湿度の大きさが変化していないかをどうかを例えば30分毎に確認してもよい。つまり再度全ての浴室外部空間それぞれの空気の湿度及び温度を検知し、前回の湿度及び温度の検知結果と変化がなければそのまま乾燥運転を継続する。また、変化があれば再度吸気開始から絶対湿度を算出する手順(図4:S04)から行い絶対湿度を比較する。
Moreover, after stopping a heating means, the moisture content of a dry target object can further be reduced by making larger the air volume which blows off from the bathroom inner suction port to bathroom exterior space than the air volume which blows off into bathroom interior space.
Moreover, since the absolute humidity of the air in the bathroom exterior space in various air environments can be compared by performing the intake from the outdoors, the effect that the drying can be performed efficiently can be further enhanced.
(Modification)
In the above embodiment, the bathroom outside humidity detection means 13 and the bathroom outside temperature detection means 14 are installed inside the main body of the bathroom ventilation dryer 1. In this case, after changing the suction air volume (FIG. 4: S08), for example, every 30 minutes, it is confirmed whether or not the absolute humidity of the air outside the bathroom has changed due to weather changes or the like. Good. That is, the humidity and temperature of the air in all the bathroom exterior spaces are detected again, and if there is no change from the previous humidity and temperature detection results, the drying operation is continued as it is. If there is a change, the absolute humidity is compared again from the procedure of calculating the absolute humidity again from the start of intake (FIG. 4: S04).
なお、浴室外側湿度検知手段13と浴室外側温度検知手段14を必ずしも浴室換気乾燥機1の本体内部に設置する必要はない。例えば吸気口9付近及び本体操作リモコン15に取り付けた場合は、浴室外側湿度検知手段13と浴室外側温度検知手段14が浴室外部空間の湿度及び温度を検知する際に、浴室外側吸込口6を開く必要がない。   The bathroom outside humidity detecting means 13 and the bathroom outside temperature detecting means 14 are not necessarily installed in the main body of the bathroom ventilation dryer 1. For example, when attached to the vicinity of the air inlet 9 and the body operation remote controller 15, the bathroom outside air inlet 6 is opened when the bathroom outside humidity detecting means 13 and the bathroom outside temperature detecting means 14 detect the humidity and temperature of the bathroom outside space. There is no need.
また、吸込風量変更手段24は、浴室外部空間から浴室換気乾燥機1に空気を吸込む際、最も絶対湿度の小さい浴室外部空間の浴室外側吸込口を開き、その他の浴室外側吸込口を閉じる制御のみだけでなく、複数の浴室外側吸込口を開くことで複数の浴室外部空間から空気を吸込む制御としても良い。つまり上記実施の形態では、複数の浴室外部空間から浴室換気乾燥機1に吸込む空気の風量の割合を0対100あるいは100対0とした。しかし省エネルギーの観点から、浴室外部空間の絶対湿度と温度から加熱手段19の使用を抑制し、例えば20対80などの風量の割合にする制御を行っても良い。   Further, the suction air volume changing means 24 opens only the bathroom outside suction port in the bathroom outside space having the lowest absolute humidity and closes the other bathroom outside suction ports when air is sucked into the bathroom ventilation dryer 1 from the bathroom outside space. Moreover, it is good also as control which sucks in air from several bathroom exterior space by opening several bathroom outer side inlets. That is, in the said embodiment, the ratio of the air volume of the air suck | inhaled into the bathroom ventilation dryer 1 from several bathroom exterior space was set to 0 to 100 or 100 to 0. However, from the viewpoint of energy saving, the use of the heating means 19 may be suppressed from the absolute humidity and temperature of the bathroom exterior space, and control may be performed so that the air volume ratio is, for example, 20 to 80.
本発明は、絶対湿度を比較し複数の浴室外部空間から空気を取り込むことができる浴室暖房装置として有用である。   INDUSTRIAL APPLICABILITY The present invention is useful as a bathroom heating device that compares absolute humidity and can take in air from a plurality of bathroom exterior spaces.
