Abstract

The invention provides an air conditioner indoor unit capable of reversibly supplying air and an air conditioner. The air conditioner indoor unit comprises a shell, a first air opening, a second air opening and a fan set, wherein an internal air channel is formed in the shell, one end of the internal air channel communicates with the first air opening, the other end of the internal air channel communicates with the second air opening, and the fan set is arranged in the internal air channel; the fan set comprises a first axial flow fan blade and a second axial flow fan blade, and the first axial flow fan blade is arranged close to the first air opening, and the axial direction of the first axial flow fan blade faces the first air opening; and / or the second axial flow fan blade is arranged close to the second air opening, and the axial direction of the second axial flow fan blade faces the second air opening. According to the air conditioner indoor unit, the purpose of improving the heatexchange effect in a room can be achieved whether in summer or winter, the shower-type upward air exhaust is achieved through refrigeration in summer, the carpet type downward air exhaust is achievedthrough heating in winter, airflow impact loss caused by air exhaust or air intake can be avoided or reduced, the air supply distance is improved, and remote air supply is facilitated.

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 airflow blown by the fan is often directly blown to the casing, and then blown out from the air outlet. Such airflow causes impact and energy loss of the airflow, increases...
