Air conditioner

Abstract

The invention discloses an air conditioner. The air conditioner comprises a shell, a draught fan, a heat exchanger, a filter screen module and a speed measuring module. The shell is provided with an air return opening and an air outlet. The draught fan is arranged in the shell and used for blowing return air, entering the shell from the air return opening, out of the air outlet, and the heat exchanger is arranged in the shell and located on an air duct between the air return opening and the air outlet. The filter screen module is arranged in the shell, located on the side, close to the air return opening, of the heat exchanger and comprises a filter screen. The speed measuring module is arranged between the filter screen module and the heat exchanger and configured to measure the actual air speed of the return air entering the shell from the air return opening after the return air is filtered by the filter screen module. According to the air conditioner, the speed measuring module is arranged between the filter screen module and the heat exchanger and directly measures the air speed of the air filtered by the filter screen, and therefore the influence of other factors on judgment of the filth blockage condition of the filter screen is avoided, and the replacement time of the filter screen can be accurately mastered.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an air conditioner. Background technique [0002] Air conditioner filters are generally replaced according to the cycle or reminders recommended by the manufacturer. However, due to the different frequency of use and environment of different air conditioners, there are deviations in measurement and calculation, so the replacement time cannot be accurately controlled. If the replacement is too early, the filter material will be wasted. If the replacement is too late, the reliability of the unit will be reduced, the energy consumption will increase, and it will cause secondary air pollution. Contents of the invention [0003] The invention provides an air conditioner to better grasp the replacement time of the filter screen of the air conditioner. [0004] The invention provides an air conditioner, comprising: [0005] A casing, the casing is provided with an air return por...
