Abstract
The invention discloses an air conditioner with filter screen cleaning prompt function and a filter screen cleaning prompt method thereof. The method comprises the following steps that: a, speed meter detects the rotating speed of an internal motor and transmitting the rotating speed signal to a main controller; a timer starts timing and transmits a time period signal ti to the main controller; b, the main controller determines and selects a corresponding equivalent time coefficient beta i according to the rotating speed signal of the internal motor, calculates an equivalent time Ti=beta i *ti, and stores the equivalent time signal; c, when the rotating speed of the internal motor is changed, the steps a and b are repeated, the equivalent time signal is stored again, and the equivalent time signals are accumulated as T=sigma beta i*ti; and d, the main controller compares the equivalent time T with the set cleaning time T0 of the system; when the T is smaller than the T0, the main controller does not act; and when the T is greater than or equal to the T0, the main controller sends signals to a user interface to remind a user of cleaning the filter screen. The air conditioner is convenient to use, and is more favorable for human health.
