  In range hoods such as those described in Patent Documents 1 and 2, after most of the airflow including oil smoke and water vapor rising from below collides with the fixed hood and the current plate provided at the bottom of the movable hood, the fixed hood and movable hood It has a structure in which it is sucked from a suction port provided between the current plate and discharged to the outside. In such a structure, airflow may escape to the side of the main body, and it is required to improve the collection efficiency of oily smoke and water vapor.

  The oil smoke sucked into the intake flow passage is a phenomenon that is especially seen when the room temperature is low, but is likely to condense on the surface of the current plate. For this reason, the current plate is subjected to a surface treatment such as fluorine processing, and the current plate is easily removed to prevent dew condensation, and the surface of the current plate is easily wiped off during routine maintenance to improve the cleaning performance.

  However, the range hood is installed on the wall side (back side) of a high place, the current plate itself is large and cannot be moved, so it is difficult for the user to wipe the current plate when cleaning it. There was also a problem that it was difficult to remove.

  In addition, in the range hoods described in Patent Documents 1 and 2, a fixed hood / movable hood and a rectifying plate are used so that oil smoke or steam can be sucked in any position of the IH cooking heater or the gas stove. The opening width (the distance between the fixed hood / movable hood and the rectifying plate) of the suction port provided between the two is formed substantially uniformly. The rectifier plate on the movable hood side moves with the movement of the movable hood, but since this rectifier plate is fixed to the movable hood, the opening width of the suction port provided between the movable hood and the rectifier plate is It does not change. For this reason, when grilling fish or the like using a grill (heating means) provided in an IH cooking heater or gas stove, the grill exhaust port is normally provided on the wall side, so that oil smoke or steam discharged from the exhaust port is provided. The oil smoke and vapor that could not be sucked in from the suction port collide with the flow straightening plate and flow to the rear of the main body, so that condensation tends to occur on the flow straightening plate and the rear wall, and there is a lot of condensed water. Then, there was a drawback of dripping. In recent years, IH cooking heaters have become widespread. However, since the IH cooking heater generates heat by induction heating due to induction heating, the temperature around the IH cooking heater does not increase so much. For this reason, since the wall around the IH cooking heater cannot be heated, the temperature difference from the oily smoke and steam generated by cooking is increased, and condensation is more likely to occur on the wall surface. And in order to prevent dripping of this dew condensation water, the user had to wipe off dew condensation water and had the subject that the effort of cleaning took.

  Moreover, in the range hood provided with the drive device as disclosed in Patent Document 2, the drive motor, the pulley connected to the shaft of the drive motor, the wire wound around the pulley, and the position detection means are provided as one plate material. Since the drive device is unitized by placing it on the drive unit, when the drive motor is damaged or failed and replaced with a new drive motor, etc., the drive device unitized on the plate is removed and replaced, so the drive motor etc. However, there is a problem that the replacement work cost and the part cost are high.
