Abstract

The invention discloses a rotating speed control method for an air purifier, which comprises the following steps: before the air purifier is started, determining the initial particle concentration CA in a room; the T-minute maximum purification particle concentration Ci of each gear is determined; according to the initial particle concentration CA in the room, the gear of the rotating speed of a fan of the air purifier is controlled; if CAgt; if CN, the air purifier operates at the Nth gear for T minutes; if so; c1, the air purifier runs for T minutes at the first gear; if Cigt; c < gt >; if the initial particle concentration CA is equal to Ci-1, the air purifier firstly runs for ti minutes at the ith gear according to the function relation between the initial particle concentration CA and the running time ti of the ith gear, and after the running time of the ith gear reaches ti, the rotating speed of a fan of the air purifier is switched to the i-1 gear to run for T-ti minutes. Based on the initial particle concentration, the gear and the operation time of the air purifier are controlled, so that it is guaranteed that the concentration of surrounding particles is rapidly reduced without influence on the air purifier, and the purification effect is better.

Description

technical field [0001] The invention relates to the technical field of speed control of a purifier fan, in particular to a method for controlling the speed of an air purifier. Background technique [0002] The fan of the air purifier has multiple gears such as high, medium and low. The conventional fan speed control method is threshold value control, that is, the particle concentration range is set for each gear, according to the sensor configured in the air purifier to measure the particle concentration. The real-time particle concentration obtained by real-time measurement, if the real-time particle concentration is within the particle concentration range of a certain gear, then the fan speed of the air purifier is controlled to operate at this gear. [0003] However, this fan speed control method has the following disadvantages: after the air purifier is running, the concentration of surrounding particles will decrease rapidly, so the air purifier will quickly drop to a l...
