Abstract

The invention provides an air conditioner indoor unit achieving reversible air supply, and an air conditioner. The air conditioner indoor unit comprises a shell body, a first air hole, a second air hole and a counter-rotating fan, wherein an inner air duct is formed inside the shell body; one end of the inner air duct is communicated with the first air hole, and the other end is communicated withthe second air hole; the counter-rotating fan is disposed inside the inner air duct; and a heat exchanger is also disposed inside the shell body, and a diversion component is also disposed between theheat exchanger and the counter-rotating fan. The air conditioner indoor unit and the air conditioner provided by the invention have the beneficial effects that a purpose of improving indoor heat exchange effects can be realized in both summer and winter; shower-type upward air discharge can be realized during refrigeration in summer, and carpet-type downward air discharge can be realized during heating in winter; unevenness of flowing of airflows between the counter-rotating fan and the heat exchanger can be reduced; an air volume can be increased; noise is reduced; and comfort felt by humanbodies indoors can be greatly improved.

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, due to the unequal axial flow area between the fan and the heat exchanger, the flow inhomogeneity of the air flow is caused, resulting in relatively large noise. [0003] Sinc...
