【発明が解決しようとする課題】高気密サッシを用いた
住宅や、マンションは建築構造から大変に気密性が高
く、自然の通風による換気は、意識して窓などを開けな

であるＬＤＫや室は居住者の呼吸により酸素が消費され
炭酸ガスが発生する。また、喫煙や発汗、衣類からの埃
等生活行動に伴って室内の空気は汚され悪化するのでこ
れを改善するためには換気が必要である。A house or a condominium using a highly airtight sash has a very high airtightness due to its architectural structure, and ventilation by natural ventilation cannot be expected unless windows are opened with consciousness. On the other hand, in the LDK or the room, which is the living space of the resident (resident), oxygen is consumed by respiration of the resident and carbon dioxide is generated. In addition, indoor air is polluted and deteriorated with living activities such as smoking, sweating, and dust from clothes, so ventilation is necessary to improve the situation.
【０００４】居住者１人当りの必要換気風量は居住者の
活動状態によっても変化するが、２〜３０ｍ3 ／ｈが適
当とされている。多ければ換気は良好であるが、室内空
調に悪影響を及ぼす。[0004] The required ventilation air volume per occupant varies depending on the activity of the occupant, but it is considered that 2 to 30 m 3 / h is appropriate. If it is large, ventilation is good, but it has a bad effect on indoor air conditioning.
【０００５】前述のように、ＬＤＫや室などの居室を換
気するには、小風量の換気扇を設置すれば良いが、その
ようにすると外壁に穴をあけることになって外観見栄え
が悪いし、建築構造から穴をあけることができない場合
がある。[0005] As described above, in order to ventilate a living room such as an LDK or a room, it is sufficient to install a ventilation fan having a small air volume. However, if this is done, a hole is formed in the outer wall, and the appearance is poor. It may not be possible to drill holes from the building structure.
【０００６】例えば、通常居住者が２〜４人のマンショ
ンの場合には、１００ｍ3 ／ｈ未満の小風量の換気扇を
ＬＤＫや室のベランダの戸の上壁に設置すればよいが、
マンションは外壁がコンクリートであり、かつこの部分
には建屋強度上必要な鉄骨が走っており、換気扇を取付
ける穴をあけることが出来ない。For example, in the case of a condominium where two or four residents are usually present, a ventilation fan with a small air volume of less than 100 m 3 / h may be installed on the upper wall of the LDK or the veranda of the room.
In the apartment, the outer wall is made of concrete, and the steel frame required for building strength runs in this part, so it is not possible to drill holes for installing ventilation fans.
【０００７】このことから、レンジフードを居室の換気
として利用することが考えられるが、レンジフードは４
００ｍ3 ／ｈ以上の大風量であるから、居室の換気とし
て利用すると前述のように換気風量が多過ぎて室内空調
に悪影響を及ぼす。From this, it is conceivable to use the range hood for ventilation of the living room.
Since it is a large air volume of 00 m 3 / h or more, if it is used for ventilation of a living room, as described above, the ventilation air volume is too large and adversely affects indoor air conditioning.
【０００８】具体的には、レンジフードの送風機のモー
タはコンデンサ誘導電動機を用い、モータに巻込まれた
強、中、弱のコイル（巻線）のいずれかに通電すること
でモータの回転数をコントロールしてレンジフードを強
運転、中運転、弱運転に切替えている。Specifically, the motor of the blower of the range hood uses a condenser induction motor, and energizes one of strong, medium and weak coils (windings) wound on the motor to reduce the rotation speed of the motor. The range hood is switched between strong operation, medium operation and weak operation by controlling.
【０００９】一方、レンジフードの強運転時の風量は５
００〜６００ｍ3 ／ｈであり、このレンジフードの風量
を１００ｍ3 ／ｈ以下とすることはモータのコア（鉄
心）のサイズ（大きさ）から困難である。On the other hand, when the range hood is operated strongly, the air volume is 5
A 00~600m 3 / h, it is difficult from the size (magnitude) of a motor core (iron core) to the air volume of the hood and 100 m 3 / h or less.

６００ｍ3 ／ｈのレンジフードのモータの「弱」は限度
があり、通常１５０ｍ3 ／ｈに設定する事は大変困難で
ある。Further, the output of the motor is reduced by weakening the output of the motor.
Although it is conceivable that the output is set to 0 m 3 / h or less, if the output of the motor is reduced, a problem occurs in starting. In the case of a normal 100 V motor, this means that a "strong" coil (tap) rotates (starts) even if a voltage of 2 to 30 V is applied, but a "weak" coil applies a voltage of about 80 V. Otherwise, it will not rotate (start). For this reason, it is 500-
The "weakness" of a range hood motor of 600 m 3 / h has a limit, and it is usually very difficult to set it to 150 m 3 / h.

して室内空調に悪影響を及ぼすことがない。Accordingly, since the living room can be ventilated by using the exhaust duct 21 for the range hood, there is no need to make a special hole for ventilation in the building frame or to attach an exhaust duct or duct piping. In addition, since the small blower 30 dedicated to room ventilation is provided with a small airflow separately from the large blower 14 having a large airflow for the range hood, the ventilation airflow in the living room is set to a predetermined airflow, and there is no adverse effect on the indoor air conditioning.

することができる。Since the small blower 30 sucks air from the air inlet 36 of the curtain plate 35, the room ventilation is performed from a position close to the ceiling. For this reason, for example, gas such as smoke and steam that is to be exhausted and floats near the ceiling can be effectively exhausted to the outside, and the small blower 30 is constantly driven so that the smoke that overflows from the hood body 1 of the range hood during cooking can be obtained. Etc. can be discharged.
