Abstract

The invention provides an air conditioner indoor unit with reversible air supply and an air conditioner. The air conditioner indoor unit comprises a shell, a first air opening, second air openings anda counter-rotating fan, wherein an internal air duct is formed in the shell, one end of the internal air duct communicates with the first air opening, the other end of the internal air duct communicates with the second air openings, and the counter-rotating fan is arranged in the internal air duct; the cross section of the shell is of a polygonal structure, and the second air openings are arranged at the lower part of the shell, and the second air openings are arranged on more than two sides of the shell with the polygonal structure. According to the invention, the air conditioner indoor unitcan realize cooling in summer and shower type upper air outlet, heating in winter and carpet type lower air outlet; airflow circulation area of air inlet or air outlet can be improved, the airflow non-uniformity between the counter-rotating fan and a heat exchanger can be reduced, and the noise can be reduced.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner indoor unit and an air conditioner with reversible air supply. Background technique [0002] The existing air-conditioning cabinets are mostly centrifugal cabinets or cross-flow cabinets, which have a single air supply mode. Both cold and hot air are blown out from the same air outlet, and only rely on the air guide mechanism to deflect the wind direction. If there is a long distance, in the heating mode, most of the hot air starts to float before reaching the ground, and in the cooling mode, most of the cold air begins to sink before reaching the roof, resulting in uneven temperature distribution in the room, poor user comfort, and long heat exchange time. Moreover, the air supply area (comprising the air outlet area and the air inlet area) of the indoor unit is small so that a large area of ​​air inlet cannot be realized, resulting in a l...
