Description

  The present invention relates to dirt removal of an exhaust impeller and an oil collecting mechanism by automatic cleaning of a range hood.

  Conventionally, this type of range hood is provided with an oil collecting mechanism for the purpose of collecting oily smoke, dust, and the like generated during cooking. Since the oil collecting mechanism part is contaminated with use, the performance deteriorates or oil dripping occurs from the collecting part, so it is necessary to periodically clean the oil collecting mechanism part. The same applies to the impeller provided for exhaust.

  In addition, as a means for automatically purifying the oil collecting mechanism for the purpose of reducing the time and effort of cleaning, there is a method of removing dirt by centrifugal force by attaching and rotating a drive device to the oil collecting mechanism. (For example, see Patent Document 1).

  Hereinafter, the range hood will be described with reference to FIG.

  As shown in FIG. 4, the dirty air 101 passes through a suction port 102, passes through a filter 104 disposed in front of the exhaust impeller 103, and rotates the filter 104. By providing the sensor 106 for detecting dirt, the dirt of the filter 104 is detected, the filter 104 is rotated by the driving device 105, and the dirt is removed by centrifugal force.
