Description

Large air purifier for schools or academies}

The present invention relates to a large air purifier for schools or academy excellent in indoor air purification efficiency and noise suppression effect.

In general, an air purifier includes a main body having a suction port and a discharge port formed therein, and the main body includes a blower that provides a blowing force for introducing contaminated air into the main body through the suction port and discharging the purified air to the outside of the main body through the discharge port; And a filter for removing contaminants in the air introduced into the main body.

The air purifier also has a pollution level sensor such as a dust sensor or an odor sensor, and the air pollution level is measured by the pollution level sensor. When the air pollution level is large, the air cleaner increases the air volume by increasing the output of the blower, and the air pollution level When low, the output of the blower is lowered to reduce the air volume of the air cleaner.

However, as described above, the method of controlling the air volume of the air cleaner only based on the degree of air pollution may take into account that the air cleaner may generate more noise as the air volume increases, thereby causing inconvenience to the user. I'm not doing it. For example, if a large air purifier is operated in a quiet environment such as a school class, increasing the air volume of the air purifier according to the indoor air pollution level may cause the class atmosphere to become unclean due to the noise generated by the air purifier. The air purifier should be operated with the airflow significantly lowered because it can damage the students studying. As a result, the school does not sufficiently clean the air in the classroom, which does not properly utilize the performance of the high performance large air purifier. It is true.
