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および図２に示すように、浴室換気乾燥機は、冷媒を圧縮するための圧縮機１と、通過する空気に放熱するための第一熱交換器２と、前記冷媒を膨張するための膨張機構３と、前記通過する空気から吸熱するための第二熱交換器４と、前記圧縮機１、前記第一熱交換器２、前記膨張機構３、前記第二熱交換器４という順に連結し前記冷媒を流通させるための冷媒配管５と、浴室６から空気を吸い込み、前記第二熱交換器４、前記第一熱交換器２の順に空気を流通させ、再度前記浴室６に空気を吹き出す循環送風手段７を箱状の外郭８に配置する。前記外郭８には換気送風手段９が連通ダンパー１０を介して連通される。 (Embodiment 1)
As shown in FIGS. 1 and 2, the bathroom ventilation dryer includes a compressor 1 for compressing the refrigerant, a first heat exchanger 2 for dissipating heat to the passing air, and an expansion of the refrigerant. The expansion mechanism 3, the second heat exchanger 4 for absorbing heat from the passing air, the compressor 1, the first heat exchanger 2, the expansion mechanism 3, and the second heat exchanger 4 are connected in this order. Then, air is sucked in from the refrigerant pipe 5 for circulating the refrigerant and the bathroom 6, air is circulated in the order of the second heat exchanger 4 and the first heat exchanger 2, and the air is blown out to the bathroom 6 again. Circulating air blowing means 7 is arranged in a box-shaped outer shell 8. A ventilation air blowing means 9 is communicated with the outer shell 8 via a communication damper 10.

前記換気送風手段９は通気ダクト１１を介して、洗面所１２およびトイレ１３と繋がる。乾燥運転を開始すると、前記圧縮機１が作動し、前記第一熱交換器２、前記膨張機構３、前記第二熱交換器４という順に前記冷媒が前記冷媒配管５を経由して流通する。また、前記循環送風手段７が作動し、前記浴室６から空気を吸い込み、前記第二熱交換器４、前記第一熱交換器２の順に空気を流通させ、再度前記浴室６に空気を吹き出す。このとき、前記浴室６から吸い込まれた空気は、冷媒が流通している前記第二熱交換器４、および前記第一熱交換器２を流通するときに熱交換を行なうが、前記第二熱交換器４では前記浴室６から吸い込まれた空気は吸熱され、結露し除湿される。その後前記第一熱交換器２を通過するときには放熱されるので、結果的に前記浴室６から吸い込まれた空気は、再熱除湿され再度前記浴室６に吹き出され、前記浴室６に配置された衣類１４の乾燥が促進されることになる。また乾燥運転中、前記換気送風手段９が作動し、連通ダンパー１０が所定の開度開くことにより前記浴室６から前記換気送風手段９までの風路が形成され、前記通気ダクト１１を介して前記換気送風手段９と繋がる前記洗面所１２、および前記トイレ１３と合わせて前記浴室６からも前記換気送風手段９へ空気が吸い込まれ、排気ダクト１５を経由して前記浴室６内の空気も屋外へ排出される。乾燥運転中に前記浴室６の空気を屋外に排出する目的は前記浴室６内に、前記衣類１４などから発生した臭いがこもらないようにすることであるが、その換気送風量が多くなると前記浴室６内の湿度が高くなり前記衣類１４の乾燥が阻害されるので、前記衣類１４の乾燥を促進するために、前記換気送風量は最低限になるように前記換気送風手段９の回転数、および前記連通ダンパー１０の開度は制御され作動する。乾燥運転中、前記浴室６から吸い込まれた空気は、再熱除湿され、再度前記浴室６に吹き出されるが、長時間乾燥運転を継続すると、徐々に前記浴室６内の空気の温度が上昇する。その結果、温度が高くなった空気を吸い込んで乾燥運転を行なうと、前記圧縮機１の吐出温度が高くなり、その吐出温度が前記圧縮機１の仕様（保証している）範囲を超えそうになると、前記圧縮機１を保護するために前記圧縮機１の作動を停止せざるを得なくなる。つまり、前記浴室６内の空気の温度が高くなってくる（例えば４０℃位）と前記圧縮機１を保護するために、前記圧縮機１は作動と停止を繰り返す、いわゆる間欠運転をし、結果的に前記衣類１４の乾燥にかかる時間が長くなってしまう。この前記圧縮機１の間欠運転を避けるために、前記浴室６内の空気温度を検知するための温度検知手段１６（一例としてサーミスター）を、前記浴室６から吸い込まれた空気が流通する風路で、かつ前記第二熱交換器４の上流側に設け、前記温度検知手段１６が所定の温度以上、例えば３０℃以上を検知すると、前記浴室６からの換気送風量を多くする、例えば３〜４倍にするために、前記換気送風手段９の回転数、および前記連通ダンパー１０の開度を変更して制御する。その結果、再熱除湿された空気が吹き出されることにより温度が高くなった前記浴室６内の空気は、前記連通ダンパー１０、前記換気送風手段９、および排気ダクト１５を経由して、より多く屋外に排出されるため、前記浴室６内の空気の温度上昇は抑えられ、前記圧縮機１は間欠運転をすることなく作動し、前記衣類１４の乾燥が阻害されることはなくなる。   The ventilation fan 9 is connected to a toilet 12 and a toilet 13 through a ventilation duct 11. When the drying operation is started, the compressor 1 is operated, and the refrigerant flows through the refrigerant pipe 5 in the order of the first heat exchanger 2, the expansion mechanism 3, and the second heat exchanger 4. Moreover, the said circulation ventilation means 7 act | operates, air is suck | inhaled from the said bathroom 6, air is distribute | circulated in order of the said 2nd heat exchanger 4 and the said 1st heat exchanger 2, and air is blown out to the said bathroom 6 again. At this time, the air sucked from the bathroom 6 exchanges heat when it flows through the second heat exchanger 4 and the first heat exchanger 2 through which the refrigerant flows. In the exchanger 4, the air sucked from the bathroom 6 is absorbed, dewed and dehumidified. After that, since the heat is dissipated when passing through the first heat exchanger 2, the air sucked from the bathroom 6 as a result is reheated and dehumidified and blown out again to the bathroom 6, and the clothes disposed in the bathroom 6. 14 drying will be promoted. Further, during the drying operation, the ventilation air blowing means 9 is operated, and the communication damper 10 is opened by a predetermined opening, whereby an air passage from the bathroom 6 to the ventilation air blowing means 9 is formed, and the air duct 11 passes through the ventilation duct 11. Along with the toilet 12 connected to the ventilation fan 9 and the toilet 13, air is also drawn into the ventilation fan 9 from the bathroom 6, and the air in the bathroom 6 is also discharged to the outdoors via the exhaust duct 15. Discharged. The purpose of discharging the air of the bathroom 6 to the outside during the drying operation is to prevent the smell generated from the clothing 14 and the like from being trapped in the bathroom 6, but when the ventilation air flow increases, the bathroom 6, the humidity of the garment 14 becomes high and the drying of the garment 14 is impeded. Therefore, in order to promote the drying of the garment 14, The opening degree of the communication damper 10 is controlled and operated. During the drying operation, the air sucked from the bathroom 6 is reheated and dehumidified and blown out again to the bathroom 6. If the drying operation is continued for a long time, the temperature of the air in the bathroom 6 gradually increases. . As a result, when the drying operation is performed by sucking the air whose temperature has been increased, the discharge temperature of the compressor 1 is increased, and the discharge temperature is likely to exceed the specification (guaranteed) range of the compressor 1. Then, in order to protect the compressor 1, the operation of the compressor 1 must be stopped. That is, in order to protect the compressor 1 when the temperature of the air in the bathroom 6 becomes high (for example, about 40 ° C.), the compressor 1 repeats operation and stop, so-called intermittent operation. In particular, it takes a long time to dry the clothes 14. In order to avoid this intermittent operation of the compressor 1, a temperature detection means 16 (a thermistor as an example) for detecting the air temperature in the bathroom 6 is passed through the air passage through which the air sucked from the bathroom 6 circulates. And when it is provided on the upstream side of the second heat exchanger 4 and the temperature detecting means 16 detects a predetermined temperature or higher, for example, 30 ° C. or higher, the ventilation air flow rate from the bathroom 6 is increased. In order to make it 4 times, it controls by changing the rotation speed of the ventilation ventilation means 9 and the opening degree of the communication damper 10. As a result, the amount of air in the bathroom 6 that has become high in temperature due to the reheat dehumidified air being blown out passes through the communication damper 10, the ventilation fan 9, and the exhaust duct 15. Since the air is discharged outdoors, the temperature rise of the air in the bathroom 6 is suppressed, the compressor 1 operates without intermittent operation, and the drying of the clothes 14 is not hindered.

また、前記温度検知手段１６が所定の温度、例えばＴ２（後述）＝３５℃、以上を検知すると、前記循環送風手段７（例えば、遠心送風機）による循環送風量を多くする、例えば約１．５倍多くする、という構成にしてもよい。   Further, when the temperature detecting means 16 detects a predetermined temperature, for example, T2 (described later) = 35 ° C. or more, the amount of circulating air blown by the circulating air blowing means 7 (for example, centrifugal fan) is increased, for example, about 1.5. You may make it the structure of increasing twice.

また、図３に示すように、浴室換気乾燥機の動作を示すフローチャートである。   Moreover, as shown in FIG. 3, it is a flowchart which shows operation | movement of a bathroom ventilation dryer.

前記温度検知手段１６が所定の温度以上（Ｔ１＝例えば３０℃）を検知すると、前記換気送風手段９（例えば、遠心送風機）の回転数を多く、および前記連通ダンパー１０の開度を大きくして、前記浴室６からの換気送風量を多くして前記浴室６内の空気の温度上昇を抑えるが、それでもなお前記浴室６内の空気の温度が上昇し、所定の温度以上（Ｔ２＝例えば３５℃、ここでＴ２＞Ｔ１）を検知したときに、前記循環送風手段７の回転数を多くして、循環送風量を多くする。   When the temperature detection means 16 detects a temperature above a predetermined temperature (T1 = for example, 30 ° C.), the number of rotations of the ventilation blower means 9 (for example, centrifugal blower) is increased, and the opening degree of the communication damper 10 is increased. Although the ventilation air flow from the bathroom 6 is increased to suppress the temperature rise of the air in the bathroom 6, the temperature of the air in the bathroom 6 still rises and exceeds a predetermined temperature (T2 = 35 ° C., for example) When T2> T1) is detected, the rotational speed of the circulating air blowing means 7 is increased to increase the circulating air volume.

その結果、第一熱交換器２を流通する空気量が多くなり、つまり、第一熱交換器での放熱量が多くなり前記圧縮機１の吐出温度が上昇することを抑えることができるので、前記圧縮機１を保護するために前記圧縮機１を間欠運転する必要がなくなり、前記衣類１４の乾燥が阻害されることはなくなる。   As a result, the amount of air flowing through the first heat exchanger 2 increases, that is, the amount of heat dissipated in the first heat exchanger increases, and the discharge temperature of the compressor 1 can be suppressed from rising. In order to protect the compressor 1, the compressor 1 does not need to be intermittently operated, and drying of the garment 14 is not hindered.

本発明にかかる浴室換気乾燥機は、浴室温度が高くならないようにし、圧縮機を保護するために圧縮機を停止させる動作を行なわないことで、衣類乾燥時間が長くならないことを可能とするものであるので、圧縮機を搭載する乾燥機の制御方法等として有用である。   The bathroom ventilation dryer according to the present invention prevents the temperature of the bathroom from becoming high and prevents the clothes drying time from becoming long by not performing an operation of stopping the compressor in order to protect the compressor. Therefore, it is useful as a control method for a dryer equipped with a compressor.
