Air conditioner indoor unit and control method thereof

Abstract

The invention discloses an air conditioner indoor unit and a control method thereof and relates to the technical field of air conditioners. Under a condition that a relatively small space is occupied,the air conditioner indoor unit can simultaneously realize an air ventilation function and a purification function; meanwhile the air conditioner indoor unit can also realize an air ventilation function only. The air conditioner indoor unit comprises an air conditioner indoor unit housing and a fresh air purifying module which is arranged inside the air conditioner indoor unit housing; the freshair purifying module comprises a fresh air channel, a purified air channel and an air guide channel; a draught fan is arranged inside the air guide channel; the air guide channel comprises a first opening and a second opening; the first opening communicates with the inside of a room through the purified air channel and communicates with the outside of the room through the fresh air channel; the second opening communicates with the inside of the room; the draught fan can rotate forwards and backwards; when the draught fan rotates forwards, the air flow inside the air guide channel flows from the first opening to the second opening; and when the draught fan rotates reversely, the air flow inside the air guide channel flows from the second opening to the first opening.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit and a control method thereof. Background technique [0002] At present, when people use the air conditioner, they need to close the doors and windows, so as to achieve a better cooling or heating effect. But after the doors and windows are closed, the indoor space forms a closed space, and there is basically no air exchange between the indoor and the outdoor. Therefore, after using the air conditioner for a long time, the indoor air will become dirty, the concentration of PM2.5 will increase, and the CO in the indoor air will 2 The concentration will also increase. [0003] In order to purify indoor dirty air and reduce the content of carbon dioxide in indoor air, some air-conditioning indoor units are designed with a fresh air purification module, which can introduce outdoor fresh air into the room to reduce indoor carbon dioxide content...

AI Technical Summary

Problems solved by technology

However, before entering the fresh air purification module, the outdoor fresh air needs to be transported from the outside to the indoor unit of the air conditioner, and then transported indoors through the fresh air purification module, resulting in a long path for the outdoor fresh air to enter the room and a large loss of outdoor fresh air. Therefore, the air intake of outdoor fresh air is small, and it is impossible to quickly reduce the content of carbon dioxide in the indoor air.
