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.

When the air conditioner indoor unit is in a direct blowing prevention mode in a specific use process, the first air deflector 200 guides cold air blown out from the air outlet 102 upwards to blow the cold air to the roof, so that the cold air blown out from the air outlet 102 can be prevented from blowing the cold air to a person directly, and the cold air blown to the roof sinks when being scattered on the roof, so that the cold air falls from the sky, a cold but not cold feeling is brought to people, and the use experience of a user is improved, as shown in fig. 2. When the air conditioning indoor unit operates in the comfort heating mode, the first air deflector 200 guides the hot air blown out from the air outlet 102 downward, so that the hot air is blown to the ground, that is, the hot air is raised from the ground, and thus the user's comfort requirement for "head cooling and foot cooling" can be met, as shown in fig. 3.

In some embodiments of the present application, the wind guide assembly further includes: the second air deflector 300, the second air deflector 300 is movably installed at the air outlet 102 of the shell 1; the second air deflector driving device 500, the second air deflector driving device 500 may drive the second air deflector 300 to rotate between the retracted position and the open position; when the second air guiding plate 300 is located at the retracted position, the second air guiding plate 300 can shield the air outlet 102, and the first air guiding plate driving device 20 can drive the first air guiding plate 200 to cover the front panel 101 and be located above the second air guiding plate 300; when the second air guiding plate 300 is located at the open position, the second air guiding plate 300 can open the air outlet 102 and is located below the housing 1, and the first air guiding plate driving device 20 can drive the first air guiding plate 200 to move so as to guide the air outlet of the air outlet 102 to blow out upward or downward. In a specific use process, different working modes of the air conditioning indoor unit can be realized by opening the first air deflector 200 and the second air deflector 300 or only opening the second air deflector 300, so that the modes of the air conditioning indoor unit are more diversified, as shown in fig. 1, 5 and 6.

The front panel 101 of the present application is provided with a corresponding avoiding groove 1011, so that an end of the rack 213 extends out of the front panel 101 from the avoiding groove 1011 and is connected to the first air deflector 200, and the rack 213 can be ensured to move in a direction away from the rear side wall of the housing 1 under the driving of the first gear 212.

In the embodiment where there are two sets of the first air guiding plate driving devices 20, there are two corresponding avoiding grooves 1011, as shown in fig. 1 and 11.

In some embodiments, two of the rotating arms 502 are respectively connected to two ends of the second air guiding plate 300 in the length direction, and two of the driving motors 501 are respectively used for driving the two rotating arms 502, so that the second air guiding plate 300 is more stable and reliable in the rotating process, and is not easy to be jammed.

In order to further ensure that the second air deflector 300 is more stable and reliable in the rotating process and is not easy to be jammed, the number of the rotating arms 502 may be multiple, a plurality of driving motors 501 are correspondingly arranged, the plurality of rotating arms 502 are arranged at intervals, and the distance between every two adjacent rotating arms 502 is equal.

In the above embodiment, in order to make the movement of the second wind guide plate 300 more stable, guide grooves may be disposed on two opposite sidewalls of the housing 1, and the second wind guide plate 300 is slidably engaged with the guide grooves to guide the rotation of the second wind guide plate 300.

In order to reduce the air outlet noise, the first air guiding plate 200 and the second air guiding plate 300 are both arc-shaped plates, and concave surfaces of the arc-shaped plates face the inside of the casing 1. Therefore, the direction of the air blown out by the fan 103 in the casing 1 changes smoothly when the air contacts the concave surface, and the noise generated when the air is collided with the first air deflector 200 and the second air deflector 300 is relatively small, so that the running noise of the indoor unit of the air conditioner is reduced.

In addition, the radian of the second air deflector 300 is the same as that of the front panel 101 of the casing 1, so that the second air deflector 300 can be completely attached to the front panel 101 when not extending out of the casing 1, 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 scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
