The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. 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 high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding 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 evaporator 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 evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the outdoor air conditioner or the indoor air conditioner.

In the above embodiment, in order to make the movement of the air guiding plate 31 more stable, guide grooves may be disposed on two opposite side walls of the housing 1, and the air guiding plate 31 is slidably engaged with the guide grooves to guide the rotation of the air guiding plate 31.
In some embodiments of the present application, the first circular arc rack 43 and the second circular arc rack 45 are connected to the movable plate 41 in a clamping manner, and compared with a connection manner using a threaded fastening connection, the connection manner using the clamping manner is simpler and more convenient.
Specifically, the movable plate 41 is provided with a first hook and a second hook, the first arc rack 43 is provided with a first clamping portion, the first clamping portion and the first hook are clamped, the second arc rack 45 is provided with a second clamping portion, and the second clamping portion and the second hook are clamped to realize clamping connection between the first arc rack 43 and the movable plate 41.
It should be noted that: the first clamping hook, the second clamping hook and the movable plate 41 are integrally formed, so that installation errors caused by secondary installation are avoided, the installation time of the indoor unit of the air conditioner is shortened, and the installation efficiency of the indoor unit of the air conditioner is improved.
In order to reduce the wind noise, the air guiding plate 31 and the movable plate 41 are both configured as a circular arc-shaped plate, and the concave surface of the circular arc-shaped plate faces the inside of the casing 1. Therefore, the direction of the cold air blown out by the fan 2 in the casing 1 changes smoothly when the cold air contacts the concave surface, and the noise generated when the outlet air collides with the air deflector 31 and the movable plate 41 is relatively small, so that the running noise of the indoor unit is reduced.
In addition, the radian of the movable plate 41 is the same as that of the front panel 100 of the casing 1, so that the movable plate 41 can be completely attached to the front panel 100 when in the retracted position, and the appearance of the air conditioning indoor unit is more attractive.
In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
