Indoor unit of air conditioner and air conditioner

Abstract

The invention provides an indoor unit of an air conditioner and the air conditioner. The indoor unit of the air conditioner comprises an air inlet filter screen and an air conditioner panel. A transparent / non-transparent device is arranged in the area, corresponding to the air conditioner panel, of the air inlet filter screen. When the transparent / non-transparent device is in a transparent state,the dirt condition of the air inlet filter screen in the air conditioner panel can be observed through the transparent / non-transparent device. According to the indoor unit of the air conditioner and the air conditioner, the dirt accumulation condition of the inner filter screen can be visually observed through the transparent / non-transparent device arranged on the air conditioner panel, and operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioner indoor unit and an air conditioner. Background technique [0002] The air conditioner, as an adjustment device for indoor air temperature and humidity, drives the indoor air to circulate and reciprocate inside the air conditioner during normal operation, and the dirt in the air, such as dust or fibers, is intercepted by the filter of the air conditioner, so The filter screen can play a certain role in purifying the air. However, with the increase of the use time of the air conditioner, the dirt on the filter will continue to increase. On the one hand, it will block the air entering the air conditioner, reducing the air output and cooling and heating efficiency of the air conditioner; on the other hand, a large number of microorganisms will breed on the filter. Secrete various metabolites, and flow into the room with the air, causing second...

Problems solved by technology

However, this method is still an indirect detection method. The structure of the infrared detection device is complex, the cost of electronic components is high, it is always on, and it is not energy-saving, and the detection effect is related to the placement position and the infrared transmission efficiency of dust.

[0003] The above two detection methods make full use of the detection function of electrical components, but they are all indirect detection methods. When electrical components fail or dirt accumulates unevenly on the filter, the detection results will be inaccurate, and even Can not play the corresponding detection function
