[0002]

2. Description of the Related Art A range hood fan has a function of sucking, collecting and discharging so-called cooking waste air such as oily smoke, exhaust gas or steam generated during cooking. During operation, in addition to oil smoke and water vapor, indoor air is taken in and discharged, so that indoor dust and dirt are discharged together with cooking waste air, or residual operation after cooking is completed (to discharge odors, etc.). In the operation method or the function of keeping the range hood activated even after cooking is completed, dust or dust in the indoor air adheres to oil or the like attached to the range hood, and the hood portion of the range hood and the fan If the filter or the like is strongly contaminated and left as it is, a load will be applied to the motor, causing a failure or causing the expected performance not to be obtained (reducing the air volume). In addition, there is a case that it is not preferable in terms of aesthetics, and how to easily clean a range hood is a major theme in product development.

[0003] One of the conventional measures against dirt is to use a material for the exhaust fan that is difficult to get dirty, or to attach a grease filter or the like in front of the fan so that oil does not stick to the fan. , To some degree. However, oil stains are not only fans,
Because it sticks to the inside of the range hood, if it is left for a long time, oil stains may adhere to it, making it difficult to remove, or it may become tar-like and drop onto the range located at the bottom of the hood . Also, when cleaning the inside of the hood, it is necessary to face upward, which is a very laborious operation.
