Method for controlling an air cleaner
First Claim
1. A method for cleaning air regardless of initial value of air pollution in an air cleaner, comprising the steps performed in sequence of:
- a) sensing at a first time an initial value of air pollution and obtaining a first air pollution increment when the air cleaner is first powered on;
b) sensing a present value of air pollution a certain time later than said first time and obtaining a second air pollution increment;
c) obtaining a third air pollution increment from said initial value of air pollution and said present value of air pollution by subtracting said first air pollution increment from said second air pollution increment;
d) determining an air pollution grade from a plurality of air pollution grades having a plurality of blow control section set according to each of said air pollution grades by use of the third air pollution increment; and
e) controlling air blow according to a blow control section covering said third air pollution increment of said air pollution grade determined in step d).

Abstract
According to the disclosure the amount of wind for an air cleaner is controlled regardless of the initial value of the air pollution level sensed by a sensor in an air cleaner. This allows the air cleaner to efficiently perform the air cleaning regardless of the area in which the air cleaner is installed. The method for cleaning the air requires that an initial value of the air pollution is sensed. Thereafter, an air pollution grade from a plurality of air pollution grades having a plurality of blow control sections set according to each of the air pollution grades. A present value of the air pollution is then sensed. An increment of air pollution is determined from the initial value of the air pollution and the value of the air pollution sensed at a later time. Based on this increment that has been determined, the amount of air from the air cleaner is controlled depending on that increment.
