Proposal of Automatic Sirocco Fan Washing System

Household chores are an essential part of daily life. Household chores include cleaning, laundry, cooking, and many others, but it is difficult to perform them every day. In particular, cleaning grease stains is often stubborn and troublesome. In addition, many ventilation fans are complicated in shape and difficult to wash. Among exhaust fans, sirocco fans are more difficult to clean than propeller fans. It takes about an hour of hard labor to scrub them with a brush, bending over at the waist. To solve this problem, we propose a system that automatically cleans the sirocco fan of a ventilation fan by simply setting it in place. The fan of the ventilation fan is soaked in water dissolved with detergent or baking soda and fixed in the bathtub, and a brush attached to the motor brushes the spaces between the fan to remove dirt. The system then takes before and after pictures of the fan before and after cleaning, and only the fan is extracted and compared to see how much dirt has been removed.
