In the present application, an air conditioner performs a refrigeration cycle of an indoor unit of the air conditioner by using a compressor, a condenser, an expansion valve, and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged. The compressor compresses a refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the ambient environment through the condensation process. The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The indoor heat exchanger evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The indoor heat exchanger may achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioning indoor unit can adjust the temperature of the indoor space throughout the cycle. The outdoor unit of the air conditioning indoor unit refers to a portion of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioning indoor unit includes the indoor heat exchanger, and the expansion valve may be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an indoor heat exchanger. When the indoor heat exchanger is used as the condenser, the indoor air conditioning unit is used as a heater in a heating mode, and when the indoor heat exchanger is used as the indoor heat exchanger, the indoor air conditioning unit is used as a cooler in a cooling mode.

And the plurality of second fixing plates 150 are spaced apart along the length direction of the air guide plate 700. The plurality of auxiliary rotating shafts 170 connect the air deflector 700 with the casing 100, and further improve the stability of connection between the air deflector 700 and the casing 100.

In some embodiments, the auxiliary rotating shaft 170 is disposed coaxially with the second rotating shaft 140, and the auxiliary rotating shaft 170 is fixed to the bottom end of the corresponding second fixing plate 150. In some embodiments, the connection members 110 are also disposed between the auxiliary rotating shaft 170 and the corresponding connection plate 160, and the plurality of connection members 110 have the same structure. The friction between the auxiliary rotating shaft 170 and the corresponding connecting plate 160 is reduced, and the stability of the rotation of the air deflector 700 is improved.

Referring to fig. 10, in some embodiments, the first fresh air inlets are respectively disposed on two sides of the casing 100, and the number of the air deflectors 700 is the same as that of the first fresh air inlets and is disposed in a one-to-one correspondence manner. The structures on both sides of the housing 100 are arranged in mirror symmetry.

While embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations of the above embodiments may be made by those of ordinary skill in the art without departing from the scope of the present invention.
