Indoor unit of air conditioner

Abstract

The invention discloses an indoor unit of an air conditioner. An air purification device is arranged at an air outlet port or an air return port of the indoor unit of the air conditioner, the air purification device comprises a first LED lamp capable of emitting UVC, a second LED lamp capable of emitting UVA and a photocatalyst filter screen, wherein the UVA can irradiate on the photocatalyst filter screen, the UVC is used for purifying bacteria, viruses and other planktonic bacteria in air, and the UVA is matched with the photocatalyst filter screen to purify harmful gases such as TVOC, formaldehyde, hydrogen sulfide in the air; the second LED lamp can rotate relative to the photocatalyst filter screen, so that the effective irradiation area of the UVA on the photocatalyst filter screen is increased, and then the purification effect of the photocatalyst filter screen on the air is improved. The air purification device can greatly improve the air purification effect under the dual effects of the UVC and the UVA.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an indoor unit of an air conditioner with a function of sterilization and purification. Background technique [0002] After the air conditioner is used for a period of time, a large amount of dust and dirt will accumulate on the filter, evaporator and air supply system, resulting in a large number of mold, bacteria, viruses and insects. When the air conditioner works again, these bacteria and insects will be destroyed It will quickly disperse into the indoor air, increasing the bacterial content of the air. Living in this environment for a long time, people are prone to dizziness, fatigue, cold and other symptoms of "air conditioning disease" and the chance of infecting various diseases, which seriously affects the health of consumers, and dirt will also reduce the efficiency of air conditioners. Heating and cooling efficiency increases energy consumption and shortens t...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, most of them use UVC or UVA alone, and UVA needs to be used in conjunction with photocatalyst filters, which has low sterilization efficiency and poor purification effect

Moreover, the irradiation angle between UVA and the photocatalyst filter screen is fixed, so that the photocatalyst filter screen cannot be effectively irradiated, and the purification effect of the photocatalyst filter screen on the air is reduced.
