Abstract

The invention discloses a filter screen staining blocking detecting and reminding device. The filter screen blocking detecting device comprises a detecting circuit, an infrared transmitter and an infrared receiver which arranged in an air processor, the detecting circuit is connected with the infrared transmitter and the infrared receiver, drives the infrared transmitter to transmit infrared lightrays to a filter screen at an air inlet of the an air processor and controls the infrared receiver to receive infrared light rays reflected from the filter screen, and blocking degree of the filter screen is determined according to an intensity value of the infrared light rays received by the infrared receiver. The filter screen blocking reminding device comprises a main control unit which is connected with a reminding unit and the filter screen blocking detecting device, and the main control unit acquires the filter screen blocking degree from the filter screen blocking detecting device andtransmits the filter screen blocking degree to the reminding unit to display the blocking degree. The device can timely and reasonably remind a user to clean or replace a filter screen, so that the air process supplies clean air, the environmental sanitation is ensured, and physical fitness of the user is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a filter screen clogging detection and reminder device. Background technique [0002] With the improvement of people's quality of life, air conditioners have become a relatively common electrical appliance in people's daily life. However, after long-term use of the air conditioner, a lot of dust will accumulate in the filter screen at the air inlet, and bacteria will easily breed in the filter screen, and then blow out the wind that causes secondary pollution, affecting the health of indoor users. [0003] At present, in the industry, the reminder method for the clogging of the filter screen is: use the timer to set a fixed use cycle, and remind the user to clean or replace the filter screen each time after the timer expires. However, in actual use, this method cannot accurately, timely and reasonably remind the user to clean or replace the filter screen when the filter...
