 冷凍サイクルによって第二熱交換器34において回収した脱衣室4、およびトイレ5の熱が第一熱交換器32へ運ばれ、浴室3へ放熱されて浴室3が暖房される。さらに第一換気口開閉部26が閉、第二換気口開閉部27が閉、24時間換気口開閉部42が開にされることにより、換気風から熱の回収をする必要がない暖房運転以外の運転がおこなわれる場合、換気風が本体部分6内に導入されることなく送風機部分7から直接屋外に排気される。その結果、換気風が第一熱交換器32、第二熱交換器34通過時の圧力損失を受けずにすみ、換気時の効率が向上する。 The heat of the dressing room 4 and the toilet 5 collected in the second heat exchanger 34 by the refrigeration cycle is transferred to the first heat exchanger 32, and is radiated to the bathroom 3 to heat the bathroom 3. Furthermore, the first ventilation opening / closing part 26 is closed, the second ventilation opening / closing part 27 is closed, and the ventilation opening / closing part 42 is opened for 24 hours. When the above operation is performed, the ventilation air is directly exhausted from the blower portion 7 to the outside without being introduced into the main body portion 6. As a result, the ventilation air does not receive pressure loss when passing through the first heat exchanger 32 and the second heat exchanger 34, and the efficiency during ventilation is improved.
 また蓋45が第三送風口43から、蓋46が第四送風口44から取り外され、それぞれが第一送風口38と、第二送風口39とを塞ぐ。そして送風機部分7が180度回転されることにより、第三送風口43が第一換気口24に、第四送風口44が第二換気口25に連接されて設置される。その結果、左右どちらからでも吸込みおよび排気ができ、排気ダクトの引回し方向の自由度が高められる。 Also, the lid 45 is removed from the third air outlet 43 and the lid 46 is removed from the fourth air outlet 44, and each of them closes the first air outlet 38 and the second air outlet 39. When the blower portion 7 is rotated 180 degrees, the third ventilation port 43 is connected to the first ventilation port 24, and the fourth ventilation port 44 is connected to the second ventilation port 25. As a result, suction and exhaust can be performed from both the left and right sides, and the degree of freedom in the direction in which the exhaust duct is routed is increased.
 浴室換気口開閉部23が開、第一換気口開閉部26が開、第二換気口開閉部27が開、24時間換気口開閉部42が開にされることにより、浴室3の空気が屋外に排気される。さらに循環吸込口開閉部22が閉、浴室換気口開閉部23が開、第一換気口開閉部26が閉、第二換気口開閉部27が閉、再熱送風口開閉部30が開とされることにより、浴室3の空気が浴室換気口21から本体部分6に吸込まれる。そして浴室3の空気が第二熱交換器34、再熱送風口29、第一熱交換器32、循環送風機8、循環吹出口20の順に送風されることにより、浴室3が再熱除湿される。 The bathroom vent opening / closing unit 23 is opened, the first ventilation port opening / closing unit 26 is opened, the second ventilation port opening / closing unit 27 is opened, and the 24-hour ventilation port opening / closing unit 42 is opened. Exhausted. Furthermore, the circulation inlet opening / closing part 22 is closed, the bathroom ventilation opening / closing part 23 is opened, the first ventilation opening / closing part 26 is closed, the second ventilation opening / closing part 27 is closed, and the reheat air blowing opening / closing part 30 is opened. As a result, the air in the bathroom 3 is sucked into the main body portion 6 from the bathroom vent 21. The bathroom 3 is reheated and dehumidified by blowing air in the order of the second heat exchanger 34, the reheat air outlet 29, the first heat exchanger 32, the circulation fan 8, and the circulation outlet 20. .
 上記構成において、再熱除湿運転がおこなわれた時、温度センサ47にて浴室3の温度が検出される。浴室3の温度が規定温度以下の場合、暖房運転がおこなわれ浴室3の温度が上昇する。浴室3の温度が規定温度を超えた時、再熱除湿運転に切り換えられることにより、冷凍サイクルにおける低温時の除湿能力の低下が素早く解消され、乾燥性能が向上する。ここで規定温度とは、再熱除湿運転時で浴室3内が低温の場合に暖房運転と再熱除湿運転とを切換える浴室3の温度の閾値であり、例えば20℃である。 In the above configuration, when the reheat dehumidifying operation is performed, the temperature sensor 47 detects the temperature of the bathroom 3. When the temperature of the bathroom 3 is equal to or lower than the specified temperature, the heating operation is performed and the temperature of the bathroom 3 rises. By switching to the reheat dehumidifying operation when the temperature of the bathroom 3 exceeds the specified temperature, a decrease in the dehumidifying ability at a low temperature in the refrigeration cycle is quickly eliminated, and the drying performance is improved. Here, the specified temperature is a threshold value of the temperature of the bathroom 3 that switches between the heating operation and the reheat dehumidifying operation when the temperature in the bathroom 3 is low during the reheat dehumidifying operation, and is 20 ° C., for example.
 また、再熱除湿運転がおこなわれた時、浴室3の温度が規定温度以下の場合、第1の時間暖房運転をおこなって浴室3の温度を上昇させ、第1の時間経過後に再熱除湿運転に切り換える。このことにより、冷凍サイクルにおける低温時の除湿能力の低下が素早く解消され、乾燥性能が向上する。ここで第1の時間とは、再熱除湿運転時で浴室3内が低温の場合に暖房運転と再熱除湿運転とを切換える時間であり、例えば10分である。 Further, when the reheat dehumidifying operation is performed, if the temperature of the bathroom 3 is lower than the specified temperature, the first time heating operation is performed to increase the temperature of the bathroom 3, and the reheat dehumidifying operation is performed after the first time has elapsed. Switch to. By this, the fall of the dehumidification capability at the time of the low temperature in a refrigerating cycle is eliminated rapidly, and drying performance improves. Here, the first time is a time for switching between the heating operation and the reheat dehumidification operation when the temperature in the bathroom 3 is low during the reheat dehumidification operation, and is, for example, 10 minutes.
 また、再熱除湿運転が終了した後に第2の時間、換気送風機9が運転され、浴室換気口開閉部23が開、第一換気口開閉部26および第二換気口開閉部27が開とされる。このことにより、再熱除湿運転中に浴室3にこもった衣類などから発生する臭いが、浴室換気空調装置の運転終了後に屋外へ排出される。ここで第2の時間とは、再熱除湿運転終了後に浴室3内を換気する時間であり、例えば30分である。 Further, after the reheat dehumidifying operation is finished, the ventilation fan 9 is operated for a second time, the bathroom vent opening / closing part 23 is opened, the first ventilation opening / closing part 26 and the second ventilation opening / closing part 27 are opened. The As a result, odors generated from clothes and the like that are trapped in the bathroom 3 during the reheat dehumidifying operation are discharged to the outside after the operation of the bathroom ventilation air conditioner is completed. Here, the second time is a time for ventilating the inside of the bathroom 3 after the end of the reheat dehumidifying operation, for example, 30 minutes.
 また、再熱除湿運転が終了した後に第2の時間、換気送風機9が運転される際、浴室換気口開閉部23、第一換気口開閉部26、および第二換気口開閉部27の開度が任意に調整されるようにした。このことにより、再熱除湿運転中に浴室3にこもった衣類などから発生する臭いが浴室換気空調装置の運転終了後に効率良く屋外へ排出される。 In addition, when the ventilation fan 9 is operated for the second time after the reheat dehumidification operation is finished, the opening degree of the bathroom vent opening / closing unit 23, the first ventilation port opening / closing unit 26, and the second ventilation port opening / closing unit 27 is opened. Was adjusted arbitrarily. As a result, the odor generated from the clothes and the like that are trapped in the bathroom 3 during the reheat dehumidifying operation is efficiently discharged to the outdoors after the operation of the bathroom ventilation air conditioner is completed.
