Or exhaust air that communicates between the fan and the air outlet that communicates with the fan through the exhaust duct and the circulation air passage that communicates the fan with the air outlet facing the interior of the bathroom. A damper for changing the distribution of air to the circulation air passage and the exhaust air passage, a circulation air heating means for heating the air sucked from the bathroom, and a temperature detection means for detecting the temperature of the air in the bathroom And a control board for controlling the operation of the bathroom air conditioner, and a design panel for ensuring a design property when looking up the bathroom air conditioner from the bathroom, the control board includes the main body. When driving Based on the temperature of the temperature detection unit detects, with the configuration that actuates the damper by selecting a suitable operation pattern from a plurality of operation patterns determined in advance.

これにより、浴室の温度を温度検知手段で検知して制御基板で好適なパターンを選出しダンパーを作動させることとなるので、外気の温度によって好適な循環空気の量と排気空気の量を分配し衣類等の乾燥時間を短くしたりランニングコストを低くすることができる、という効果を奏する。   As a result, the temperature of the bathroom is detected by the temperature detection means, and a suitable pattern is selected on the control board and the damper is operated.

これにより、浴室の温度を温度検知手段で検知して、制御基板で高温時のパターンを選出しダンパーを閉める側に作動させることとなるので、外気の高温時において好適な循環空気の量と排気空気の量を分配し衣類等の乾燥時間を短くしたりランニングコストを低くすることができる、という効果を奏する。   As a result, the temperature of the bathroom is detected by the temperature detection means, and the pattern at the time of high temperature is selected by the control board and is operated to the side that closes the damper. The effect is that the amount of air can be distributed to shorten the drying time of clothes and the like and to reduce the running cost.

以下、本発明の実施の形態について図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(実施の形態1)
図1に示すように、本体1の内部には風路を兼ねた例えば樹脂製のフレーム2の内部に、送風手段としてシロッコファンであるファン3およびACモータであるモータ4とを備えている。ファン3はモータ4と接続されている。
(Embodiment 1)
As shown in FIG. 1, a main body 1 is provided with a fan 3 that is a sirocco fan and a motor 4 that is an AC motor as a blowing means inside a frame 2 made of, for example, resin that also serves as an air passage. The fan 3 is connected to the motor 4.

そして、
同じく本体1の内部には、
ファン3と、浴室16内に面した本体1の底面18の吹出口19とを連通する循環風路5と、ファン3と排気ダクト(図示せず)を通して屋外(図示せず)と連通する排気口20とを連通する排気風路6と、循環風路5と排気風路6への空気すなわち循環空気21と排気空気22の量の分配を変更するダンパー7と、ファン3が吸い込んだ空気を加熱するPTCヒーターである循環風加熱手段8と、循環風加熱手段8に対してダンパー7の方向である風上側に位置し空気の温度を検知するサーミスタセンサである温度検知手段9と、ファン3に対して浴室16の方向である風上側に位置し空気の相対湿度を検知する静電容量型湿度センサである相対湿度検知手段10と、本体1の運転を制御するためのマイコン、リレー、コンデンサ等を備えた制御基板11、とを備えている。
And
Similarly, inside the main body 1,
Exhaust air communicating with the outside (not shown) through the circulation air passage 5 that communicates the fan 3 and the air outlet 19 of the bottom surface 18 of the main body 1 facing the bathroom 16, and the fan 3 and an exhaust duct (not shown). The exhaust air passage 6 that communicates with the opening 20, the damper 7 that changes the distribution of the amount of air to the circulation air passage 5 and the exhaust air passage 6, that is, the circulation air 21 and the exhaust air 22, and the air sucked by the fan 3 Circulating wind heating means 8 which is a PTC heater to be heated, temperature detection means 9 which is a thermistor sensor which is located on the windward side in the direction of the damper 7 with respect to the circulating wind heating means 8 and detects the temperature of the air, and the fan 3 Relative humidity detection means 10 that is a capacitive humidity sensor that is located on the windward side in the direction of the bathroom 16 and detects the relative humidity of air, and a microcomputer, relay, and capacitor for controlling the operation of the main body 1 Etc. Control board 11, and a city.

そして、制御基板11はフレーム2の上部に難燃樹脂製のケースを介して取り付けられている。   And the control board 11 is attached to the upper part of the flame | frame 2 through the case made from a flame-retardant resin.

そして、浴室16の湿気や入浴時のシャワーの水の飛沫が制御基板11内に浸入しないように配慮されている。   In addition, consideration is given so that moisture in the bathroom 16 and splashes of shower water during bathing do not enter the control board 11.

そして、吹出口19には、循環風の吹出方向を変更するためのルーバー12を備えている。   And the blower outlet 19 is equipped with the louver 12 for changing the blowing direction of a circulating wind.

そして、ルーバー12は図示しないルーバー駆動用ステッピングモータと接続されており、制御基板11からの指令によってルーバー駆動用ステッピングモータを駆動させることであらかじめ決められた任意の角度まで開いたり、ユーザーが角度設定を変更することで好みの方向に風向を変化させることができる。   The louver 12 is connected to a louver driving stepping motor (not shown), and the louver driving stepper motor is driven by an instruction from the control board 11 so that the louver 12 can be opened to an arbitrary angle or set by the user. By changing the wind direction can be changed to the desired direction.

また、連続的にルーバー駆動用ステッピングモータを駆動させることで循環風の吹出方向を浴室16の隅々に向くように広角に制御することができる。   In addition, by continuously driving the louver driving stepping motor, it is possible to control the blowing direction of the circulating air to a wide angle so as to face every corner of the bathroom 16.

そして、本体1の運転を行わない場合や24時間換気機能のみを使用する場合は、循環風路5を確保する必要が無いため、意匠性確保のためルーバー12を閉じておき、暖房運転や乾燥運転を行う場合は、循環風を浴室16に吹き出す方向にルーバー12が駆動する。   When the main body 1 is not operated or when only the 24-hour ventilation function is used, it is not necessary to secure the circulation air passage 5, so the louver 12 is closed to ensure the design, and the heating operation or drying is performed. When driving, the louver 12 is driven in the direction of blowing the circulating air to the bathroom 16.

また、図2に示すように、浴室16から本体1を見上げた際の意匠性を確保するための意匠パネル13を備えている。   Moreover, as shown in FIG. 2, the design panel 13 for ensuring the design property when the main body 1 is looked up from the bathroom 16 is provided.

そして、運転モードの選択は制御基板11と通信線14を介して接続されるコントローラ15を用いてユーザーが行う。コントローラ15は浴室16の入り口の壁面、例えば脱衣室17にスイッチボックスを介して取り付けられる。   The operation mode is selected by the user using the controller 15 connected to the control board 11 via the communication line 14. The controller 15 is attached to a wall surface at the entrance of the bathroom 16, for example, a dressing room 17 via a switch box.

そして、ダンパー7は図示しないダンパー駆動用ステッピングモータと接続されており、制御基板11からの指令によってダンパー駆動用ステッピングモータを駆動することで、任意の角度までダンパーを開くことができる。   The damper 7 is connected to a damper driving stepping motor (not shown), and the damper can be opened to an arbitrary angle by driving the damper driving stepping motor according to a command from the control board 11.

ダンパーを開くとは、図3に示すように、図1よりも循環風路5側に流れる風を増やすようにダンパー7を駆動させることを意味する。   Opening the damper means that the damper 7 is driven so as to increase the wind that flows closer to the circulating air path 5 than in FIG. 1, as shown in FIG. 3.

また、本体1は、先に挙げた24時間換気機能の他に複数の運転モードを持っており、例えば暖房運転を行う際は、ダンパー7を全開になるまで駆動させてファン3から送られる風を循環風路5に導き、同時に循環風加熱手段8への通電を行うことで、循環風を加熱して温風とする。   Further, the main body 1 has a plurality of operation modes in addition to the 24-hour ventilation function mentioned above. For example, when performing heating operation, the damper 7 is driven until it is fully opened and the wind sent from the fan 3 is sent. Is supplied to the circulating air passage 5 and energized to the circulating air heating means 8 at the same time, thereby heating the circulating air to warm air.

また、乾燥運転を行う際は、ファン3からの風の一部(循環風と排気風)を循環風路5へ導き循環風加熱手段8にて加熱して温風とし、同時に風の一部を排気風路6へ送ることで、乾燥対象に温風を当てて乾かしつつ、浴室16から湿気を排出する。そのため、ダンパー7は半開きの位置まで駆動する。   Further, when performing the drying operation, a part of the wind from the fan 3 (circulation wind and exhaust wind) is led to the circulation wind path 5 and heated by the circulation wind heating means 8 to be warm air, and at the same time a part of the wind Is sent to the exhaust air passage 6, and moisture is discharged from the bathroom 16 while drying by applying warm air to the object to be dried. Therefore, the damper 7 is driven to the half-open position.

さて、従来の浴室空気調和機においては、ユーザーが乾燥運転を選択した際にダンパー7が半開きの位置まで駆動し、次いでモータ4とファン3を駆動して送風を行い、送風が始まってから循環風加熱手段8に通電するが、ダンパー7の開度はあらかじめ決められた乾燥運転用の開度で固定されるため、外気の温湿度によっては必ずしも最適な開度にならないという課題があった。   Now, in the conventional bathroom air conditioner, when the user selects the drying operation, the damper 7 is driven to the half-open position, and then the motor 4 and the fan 3 are driven to blow air. Although the wind heating means 8 is energized, the opening degree of the damper 7 is fixed at a predetermined opening degree for the drying operation, so that there is a problem that the opening degree is not always optimal depending on the temperature and humidity of the outside air.

例を挙げると、外気温度が低い際は、相対湿度の高い低いに関わらず、図3のように一般的な運転条件における乾燥運転のダンパーの開度より開ける側に動かして循環風路5側に流れる風の量を多くして浴室16内の温度を高く保つことにより、より早く乾燥対象を乾かすことができる。また、外気温度が高く相対湿度も高い際は、図4のように一般的な運転条件における乾燥運転のダンパーの開度より閉める側に動かして排気風路6側に流れる風の量を多くして浴室16内の空気を早く排出させ、より早く乾燥対象を乾かすことができる。   For example, when the outside air temperature is low, regardless of whether the relative humidity is high or low, the circulation air passage 5 side is moved to the side closer to the opening of the damper of the drying operation under general operating conditions as shown in FIG. By increasing the amount of air flowing in the bathroom and keeping the temperature in the bathroom 16 high, the object to be dried can be dried more quickly. Further, when the outside air temperature is high and the relative humidity is also high, the amount of wind flowing to the exhaust air passage 6 side is increased by moving to the side closer to the opening degree of the damper of the drying operation under general operation conditions as shown in FIG. Thus, the air in the bathroom 16 can be discharged quickly, and the object to be dried can be dried more quickly.

そして、外気温度が高くても相対湿度が低い場合は、図1のように外気温度と相対湿度が共に高い場合よりも開ける側に動かして循環風路5側に流れる風の量を多くして吹出風速を上げ、より乾燥対象に強く風を当てて乾燥を促すことで、より早く乾燥対象を乾かすことができる。本発明における浴室空気調和機は、図5に示すように、乾燥運転開始時のダンパー7の制御に関して、あらかじめパラメータ化して記憶しており、乾燥運転開始時の温度と相対湿度から好適なダンパー7の開度を選択するようになっている。   When the outside air temperature is high and the relative humidity is low, as shown in FIG. 1, the amount of wind flowing toward the circulation air passage 5 is increased by moving to the side where the outside air temperature and the relative humidity are both high. The drying target can be dried more quickly by increasing the blown-out wind speed and urging the drying target with a stronger wind. As shown in FIG. 5, the bathroom air conditioner in the present invention stores parameterized parameters in advance for controlling the damper 7 at the start of the drying operation, and is suitable for the damper 7 from the temperature and relative humidity at the start of the drying operation. The opening degree is selected.

従来の浴室空気調和機においては、例のように温湿度ごとにダンパー7の開度を調整しておらず、乾燥運転を選択した際はすべて一様のダンパー7の開度の制御としていた。   In the conventional bathroom air conditioner, the opening degree of the damper 7 is not adjusted for each temperature and humidity as in the example, and when the drying operation is selected, the opening degree of the damper 7 is uniformly controlled.

ここで、外気温度が低いとは15℃未満、好ましくは10℃未満を指し、外気温度が高いとは25℃以上、好ましくは30℃以上を指す。また、相対湿度が低いとは50%未満、好ましくは45%未満を指し、相対湿度が高いとは70%以上、好ましくは75%以上を指す。また、乾燥対象とは浴室16内に設置された図示しない物干しバーに干した衣類を指す。   Here, the low outside air temperature means less than 15 ° C., preferably less than 10 ° C., and the high outside air temperature means 25 ° C. or more, preferably 30 ° C. or more. Low relative humidity refers to less than 50%, preferably less than 45%, and high relative humidity refers to 70% or more, preferably 75% or more. The object to be dried refers to clothes dried on a clothes bar (not shown) installed in the bathroom 16.

低温である10℃または15℃等を第1所定温度、高温である25℃または30℃等を第2所定温度、低湿度である45%または50%等を第1所定湿度、高湿度である70%または75%等を第2所定湿度とすると、第1所定温度<第2所定温度、第1所定湿度<第2所定湿度となる。   A low temperature of 10 ° C. or 15 ° C. is the first predetermined temperature, a high temperature of 25 ° C. or 30 ° C. is the second predetermined temperature, a low humidity of 45% or 50% is the first predetermined humidity, and the high humidity. Assuming that 70% or 75% or the like is the second predetermined humidity, the first predetermined temperature <the second predetermined temperature, and the first predetermined humidity <the second predetermined humidity.

図5に示すパターンについて補足する。   It supplements about the pattern shown in FIG.

運転開始の際に、温度検知手段9により検知された温度を温度Tとし、相対湿度検知手段10により検知された相対湿度を相対湿度Hとする。   At the start of operation, the temperature detected by the temperature detection means 9 is defined as temperature T, and the relative humidity detected by the relative humidity detection means 10 is defined as relative humidity H.

「温度T<第1所定温度」である場合、ダンパー7の開度(パターン1)を所定開度(パターン2)より大きくして、循環風路5に流す空気の量を増やし、排気風路6に流す空気の量を減らす。   When “temperature T <first predetermined temperature”, the opening degree of the damper 7 (pattern 1) is made larger than the predetermined opening degree (pattern 2), the amount of air flowing through the circulation air passage 5 is increased, and the exhaust air passage Reduce the amount of air flowing to 6.

「第1所定温度≦温度T<第2所定温度」且つ「相対湿度H<第1所定湿度」である場合、ダンパー7の開度(パターン1)を所定開度(パターン2)より大きくして、循環風路5に流す空気の量を増やし、排気風路6に流す空気の量を減らす。   When “first predetermined temperature ≦ temperature T <second predetermined temperature” and “relative humidity H <first predetermined humidity”, the opening degree of the damper 7 (pattern 1) is set larger than the predetermined opening degree (pattern 2). The amount of air flowing through the circulation air passage 5 is increased, and the amount of air flowing through the exhaust air passage 6 is reduced.

「第1所定温度≦温度T<第2所定温度」且つ「第1所定湿度≦相対湿度H」である場合、ダンパー7の開度(パターン2)を所定開度(パターン2)と同程度にする。   When “first predetermined temperature ≦ temperature T <second predetermined temperature” and “first predetermined humidity ≦ relative humidity H”, the opening degree of the damper 7 (pattern 2) is set to the same degree as the predetermined opening degree (pattern 2). To do.

「第2所定温度≦温度T」且つ「相対湿度H<第1所定湿度」である場合、ダンパー7の開度(パターン2)を所定開度(パターン2)と同程度にする。   When “second predetermined temperature ≦ temperature T” and “relative humidity H <first predetermined humidity”, the opening degree of the damper 7 (pattern 2) is set to the same degree as the predetermined opening degree (pattern 2).

「第2所定温度≦温度T」且つ「第1所定湿度≦相対湿度H」である場合、ダンパー7の開度(パターン3)を所定開度(パターン2)より小さくして、排気風路6に流す空気の量を増やし、循環風路5に流す空気の量を減らす。   When “second predetermined temperature ≦ temperature T” and “first predetermined humidity ≦ relative humidity H”, the opening degree of the damper 7 (pattern 3) is made smaller than the predetermined opening degree (pattern 2), and the exhaust air passage 6 The amount of air flowing through the circulation air passage 5 is increased, and the amount of air flowing through the circulation air passage 5 is decreased.

なお、「第2所定温度≦温度T」且つ「第2所定湿度≦相対湿度H」である場合、ダンパー7の開度をパターン3より小さくしても良い。   Note that when “second predetermined temperature ≦ temperature T” and “second predetermined humidity ≦ relative humidity H”, the opening degree of the damper 7 may be smaller than that of the pattern 3.

また、「温度T<第1所定温度」且つ「相対湿度H<第1所定湿度」である場合、ダンパー7の開度をパターン1より大きくしても良い。   Further, when “temperature T <first predetermined temperature” and “relative humidity H <first predetermined humidity”, the opening degree of the damper 7 may be larger than that of the pattern 1.

本体1は乾燥運転モードが選択された時点における温度検知手段9の検知温度と相対湿度検知手段10から外気温度と外気相対湿度を判定するが、本体1は24時間換気機能を備えているため、浴室16内には常に室外から空気が流入しており、浴室16内の温湿度は概ね外気温度と外気相対湿度に等しくなる。ところが、乾燥運転を行う際は、ユーザーが物干しバーに衣類を吊るす間に衣類から自然に蒸発した水分の影響により、浴室16内の相対湿度は外気相対湿度より高くなる傾向がある。そこで、相対湿度を相対湿度検知手段10の読み値より一定の値、例えば5%だけ低く判定するように制御基板11に搭載したマイコンにプログラムしておくとよい。   The main body 1 determines the outside air temperature and the outside air relative humidity from the detected temperature of the temperature detecting means 9 and the relative humidity detecting means 10 at the time when the drying operation mode is selected, but the main body 1 has a 24-hour ventilation function. Air always flows into the bathroom 16 from the outside, and the temperature and humidity in the bathroom 16 are approximately equal to the outside air temperature and the outside air relative humidity. However, when performing a drying operation, the relative humidity in the bathroom 16 tends to be higher than the relative humidity in the outside air due to the influence of moisture naturally evaporated from the clothing while the user hangs the clothing on the clothes-drying bar. Therefore, it is preferable to program the microcomputer mounted on the control board 11 so that the relative humidity is determined to be lower than the reading value of the relative humidity detection means 10 by a certain value, for example, 5%.

なお、この実施の形態1では循環風加熱手段8としてPTCヒーターを用いたが、ハロゲンヒーターやカーボンヒーターを用いてもその作用に差異を生じない。また、PTCヒーターは一定の温度に達すると急激に抵抗が上昇して温度を一定に保つ特性があるため安全性が高く、浴室空気調和機に一般的に用いられている。   In the first embodiment, a PTC heater is used as the circulating air heating means 8, but even if a halogen heater or a carbon heater is used, there is no difference in operation. In addition, since the PTC heater has a characteristic that when the temperature reaches a certain temperature, the resistance rapidly increases to keep the temperature constant, the PTC heater has high safety and is generally used in a bathroom air conditioner.

また、温度検知手段9としてサーミスタセンサを用いたが、相対湿度検知手段10に温度検知機能が付帯している場合は、相対湿度検知手段10で温度と相対湿度の両方を検知しても良い。   Further, although the thermistor sensor is used as the temperature detection means 9, when the temperature detection function is attached to the relative humidity detection means 10, both the temperature and the relative humidity may be detected by the relative humidity detection means 10.

なお、本実施の形態1でサーミスタセンサを用いたのは、本実施の形態1における浴室空気調和機については、サーミスタセンサを温度検知とPTCヒーターの過昇温度上昇防止に兼用するとともに、相対湿度検知手段10で検知した温度とサーミスタセンサで検知した温度には本発明に影響を及ぼす差が発生しなかったためである。   The thermistor sensor used in the first embodiment is the same as the bathroom air conditioner in the first embodiment, in which the thermistor sensor is used for both temperature detection and prevention of excessive temperature rise of the PTC heater and relative humidity. This is because there was no difference between the temperature detected by the detection means 10 and the temperature detected by the thermistor sensor that affects the present invention.

よって、相対湿度検知手段10の温度検知機能を使用しないことで、相対湿度検知手段10と制御基板11の間の配線を減らせる上、制御基板11に搭載したマイコンのポート数を増やさないで済むため、コストの削減効果が大いに見込める。   Therefore, by not using the temperature detection function of the relative humidity detection means 10, the wiring between the relative humidity detection means 10 and the control board 11 can be reduced and the number of microcomputer ports mounted on the control board 11 does not need to be increased. Therefore, the cost reduction effect can be greatly expected.

また、本実施の形態1では送風手段としてACモータを使用しているが、DCモータを使用しても良い。DCモータを使用した場合、ACモータと比べて一般的にモータ回転数の制御性に優れるという効果が見込める。   In the first embodiment, an AC motor is used as the air blowing means, but a DC motor may be used. When a DC motor is used, an effect that the controllability of the motor rotation speed is generally superior to that of an AC motor can be expected.

本発明にかかる浴室空気調和機は、外気の温度や湿度によって好適な循環空気の量と排気空気の量を分配し衣類等の乾燥時間を短くしたりランニングコストを低くすることができることを可能とするものであるので、浴室の乾燥を行う天井埋込型の浴室暖房換気乾燥機等として有用である。   The bathroom air conditioner according to the present invention distributes a suitable amount of circulating air and exhaust air according to the temperature and humidity of the outside air, and can shorten the drying time of clothing and the like and reduce the running cost. Therefore, it is useful as a ceiling-embedded bathroom heating / ventilating dryer for drying a bathroom.
