Description

上記課題を解決するために、空気の流れを発生させるファンと、その空気の流れの流路上であってそのファンより上流側に存在し、その空気の流れを通過させる孔を有するフィルタと、そのフィルタを回転させる電動機と、そのフィルタの周囲を囲む油分捕集部材と、そのファンとその電動機の回転を制御する制御部と、を備え、その制御部は、そのファンとその電動機とを同時に回転させることがあり、制御部は、ファンの回転数を変化させ、ファンの回転数に応じて電動機の回転数を変化させることを特徴とするレンジフードが提供される。
これによれば、ファンと同時にフィルタを回転させることにより、フィルタを回転させるための電動機が発生させる騒音やフィルタの回転による風切り音を、使用者が気にならない程度のものとすることができる。また、ファンの回転即ちレンジフードの稼働と、フィルタの回転の両方を少なくとも一時点で同時に行うことにより、フィルタへの油分の付着量が少なくなり、フィルタ表面での油分の固着化を防止することができる。また、これによれば、油分が多く付着する場合にはより強い遠心力を与えてフィルタから早く油分を飛ばしてフィルタの目詰まりを防止し、油分の付着量を低減させるとともに、レンジフードの回転速度が遅い時には必要以上にフィルタを高速で回転させることを防ぐことができる。
In order to solve the above problems, a fan that generates an air flow, a filter that exists on the upstream side of the fan on the flow path of the air flow and has a hole through which the air flow passes, and An electric motor that rotates the filter, an oil collecting member that surrounds the filter, and a control unit that controls the rotation of the fan and the electric motor. The control unit rotates the fan and the electric motor simultaneously. Ri Kotogaa to, the controller changes the rotational speed of the fan, range hood, characterized in that changing the rotational speed of the motor according to the rotation speed of the fan is provided.
According to this, by rotating the filter simultaneously with the fan, the noise generated by the electric motor for rotating the filter and the wind noise caused by the rotation of the filter can be reduced to a level that the user does not care about. Also, by performing both fan rotation, that is, operation of the range hood and filter rotation at the same time at least at one point, the amount of oil adhering to the filter is reduced, and oil adhesion on the filter surface is prevented. Can do. In addition, according to this, when a large amount of oil is attached, a stronger centrifugal force is applied to expel the oil quickly from the filter to prevent clogging of the filter, reducing the amount of oil attached, and rotating the range hood. When the speed is low, it is possible to prevent the filter from rotating at a higher speed than necessary.
